TECHNICAL FIELD

The present invention relates to a closure cap and to a method for its manufacturing, which closure cap comprises a vibration damper element, and which - mounted onto a receptacle - enables vibration damped storage of various materials as well as gas-tight closure of the receptacle, and which - in an especially preferred manner - can also be manufactured as a single piece. BACKGROUND ART

A significant part of medicinal tablets does not have sufficient solidity, consequently, after being packaged, the tablets tend to crumble, pulverize within the sealed receptacle. Strengthening tablet solidity is not a solution for this problem, as the tablets have to retain to be partable and breakable. A not negligible portion of medicinal tablets are sensitive not only to pulverization but also to moisture.

In order to eliminate the problem of abrasion, there is a known solution, that some kind of resilient material or an accordion-like vibration damper element is placed above the medicaments, which is advisably attached to other parts of the closure caps in order to avoid loss or wear thereof. There is a known solution for the storage of moisture-sensitive medicaments, where a moisture absorbing, vapor binding material is placed associated with the storage space of the medicaments through a perforation or in any other way.

Additionally, another significant problem in the case of moisture-sensitive medicaments is that although a gas-tight storage is provided by the storage receptacles during manufacturing and distribution, gas-tightness may cease by the deterioration of the material of the closure cap due to its usage.

In US 4 279 351 a closure cap having an integrated vibration damper element as well as providing a gas-tight closure and re-closure is disclosed. A disadvantage of the known solution is that it does not provide any protection against weakened re-closure due to deterioration of the material of the closure cap. In this way, the closure cap is unable to provide a gas-tight closure for a longer usage period and protection against moisture for the material stored inside of the sealed receptacle . Further disadvantage of the known solution is that it is not equipped ' with a guarantee ring to prove originality.

In DE 9412075 Ul a re-closable closure cap is disclosed, which is provided with a vibration- damper element as well as a chamber filled with moisture absorbing material. In DE 20004529 Ul a re-closable closure cap is disclosed which is fitted with a chamber filled with moisture absorbing material. A similar closure cap is disclosed in EP 0 763 477 Al . In DE 2941915 Al a re-closable closure cap is disclosed which is provided with a vibration damper element, wherein the vibration-damper element is fixed to the closure cap, but is not made of a single piece. By being mounted onto receptacles, the closure caps disclosed in the aforementioned patent documents offer solutions for the vibration damping and/or moisture-sensitivity management for the materials stored within the receptacle sealed by them, however, bear at least one of the above described disadvantages.

In the light of the known solutions described hereabove, a demand has arisen for a closure cap which is exempt from the disadvantages of the above solutions, namely it is provided wit a vibration damper element, it is re-closable and is mounted onto a receptacle to protect the material stored within the receptacle from external moisture by means of a gas-tight closure and/or by the use of vapor absorbing material, moreover it has protection against deterioration of the material of the closure cap, so as to be able to maintain its advantageous characteristics for a longer period. DESCRIPTION OF THE INVENTION

It is an object of the invention to provide a closure cap fitted with a vibration damper element and preferably producible of a single piece, and to provide a manufacturing method thereof, which closure cap is exempt from the disadvantages of prior art solutions. It is an object of the invention to provide a closure cap which, when fitted onto a receptacle, is capable of ensuring a longer-term gas-tight storage of materials stored within the receptacle.

It is a further object of the invention to provide a method which offers a suitable producing method for manufacturing a closure cap integrated with a vibration-damper element.

The objects of the invention are achieved by the closure cap according to claim 1 and by the method according to claim 14. Preferred embodiments of the invention are defined in the dependent claims. The closure cap according to the invention ensures a gas-tight storage by the application of a straining insert, and the straining insert further ensures that the gas-tight closure is maintainable for an arbitrary period of time - even after an arbitrary number of removals and replacements of the closure cap, in spite of the deterioration of the material of the closure cap. In the course of the manufacturing method of the closure cap according to the invention, the connecting part of the closure cap and the vibration-damper part are advantageously joined - upon appropriate preparations - by means of injection-molding, then the final shaping of the vibration-damper element is achieved by means of blowing.

MODES OF CARRYING OUT THE INVENTION

The closure cap fitted with the vibration-damper element and optionally producible of a single piece according to the invention was developed to provide vibration-damping and a gas-tight closure when mounted onto a receptacle, thereby providing a solution for the protection of various objects placed therein against moisture, as well as ensuring to maintain a gas-tight closure for an arbitrary period of time - typically for many years - irrespective of the deterioration of the material of the closure cap or the number of removals or replacements of the closure cap. In order to ensure the above features, the closure cap according to the invention comprises a straining insert and a sealing surface supported by the correspondingly extending cylindrical side portion of the straining insert, having a protrusion formed thereon. The straining insert further comprises a lid. By introducing the straining insert into the opening formed on the closure cap, a circular protrusion is preferably created on the sealing surface, which, when mounting the closure cap onto a receptacle, circularly tightens against the mouth of the receptacle, thereby ensuring a gas-tight closure. The lid of the straining insert covers the opening formed on the closure cap. The straining insert may preferably be produced of a material harder than that of the closure cap so as to fulfill the desired object, and has numerous ways of realization, only a few of which will be disclosed in the preferred embodiments introduced herebelow.

An embodiment produced as one piece means that the so-called connecting part of the closure cap, which is the part of the closure cap beyond the vibration-damper element, and the vibration-damper element are produced as a single piece. A two-piece embodiment of the closure cap will also be disclosed, wherein the connecting part and the vibration-damper element are formed of two separate pieces.

The closure cap according to the invention is especially suitable for receptacles used for storing medicaments, in such cases when the stored medicaments tend to crumble or pulverize, i.e. vibration-damping is relevant, and/or to be moisture-sensitive, therefore gas-tight closure and appropriate placement of vapor binding material - typically silica - is to be ensured. The vibration-damper element is capable of resilient shape variation, preferably in an accordionlike manner. The closure cap according to the invention may be produced in such a way, that perforation is made on the vibration-damper element. The vibration-damper element comprises an internal space bordered from above by a straining insert that is irremovable without destruction, which internal space is suitable to store a vapor binding material, preferably a silica material. The perforation enables that the vapor binding material is connected to the internal space of the receptacle closed by the closure cap through the perforation to ensure moisture binding as well as to absorb the moisture content of the air in the internal space of the receptacle.

In case of a closed, non-perforated embodiment of the vibration-damper element of the closure cap according to the invention, the vibration-damper element also contains an internal space. If this internal space is closed by means of a straining insert manually removable and appropriately replaceable without any destruction, then the internal space is suitable to store any kind of object, preferably a sample, an advertisement, a user's manual, or a patient information, as the storage spaces formed in the internal space of the vibration-damper element and in the internal space of the receptacle are separate spaces hermetically closed from each other.

A guarantee ring is preferably fixed to the closure cap according to the invention by means of tearable strings proving originality, said guarantee ring comprises a tab protruding when the closure cap is mounted onto the receptacle, thereby assisting a separation of the guarantee ring. The closure cap further comprises a re-closing rim suitable for snapping onto a mouth of the receptacle.

The closure cap according to the invention may be produced from one or two pieces with the same functionality. In the latter case, the straining insert plays a significant role in affixing the separate parts of the closure cap to each other, so as to ensure that the closure cap can be handled as one unit, alike the one-piece embodiment.

The preferred embodiments of the closure cap as well as the manufacturing method of the closure cap will henceforward be disclosed with reference to drawings.

In Fig. 1 a cross-sectional side view of a preferred embodiment of closure cap 10 is shown, wherein a connecting part 24 and a vibration-damper element 14 are formed of one single piece and the closure cap 10 is mounted onto a receptacle 12 by means of the connecting part 24 of the closure cap 10. The vibration-damper element 14 ensures that a stored material 28 indicated in Figure 8 and placed inside of an internal space 15 of the receptacle 12 does not crumble, pulverize and that it is made more resistant against the impacts resulting from shaking. The connecting part 24 of the closure cap 10 comprises an external cylindrical mantle part 37 and an internal cylindrical mantle part 38. The vibration-damper element 14 is attached to the internal cylindrical mantle part 38; in case of a one-piece embodiment this connection is established by melting together the connecting part 24 comprising the internal cylindrical mantle part 38 and the vibration-damper element 14. The preferred embodiment comprises a straining insert 1 1 fitting into an opening 27 indicated in Fig. 3C. The straining insert 1 1 is preferably fitted with a rim 23 formed on a lid 40, said rim 23 is an element enabling nondestructive manual removal of the straining insert 1 1. By means of the rim 23, therefore, it is possible to remove the straining insert 11 from the opening 27 and to place it therein without any destruction. Therefore, in the case of a closed construction of the vibration-damper element 14, an object 13 may be placed into internal space 32 of the vibration-damper element 14. By way of example, the object 13 may be any sample, advertisement, user's manual, patient information, or any other object.

A guarantee ring 17 shown in Fig. 1 is connected to the external cylindrical mantle part 37 of the connecting part 24 by means of tearable strings 18 ensuring genuineness, which guarantee ring 17 may be torn by means of a tab 16. In order to provide for easy tearing of the guarantee ring 17, tab 16 is protruding when mounted onto the receptacle, as it is apparent from the cross-sectional side view of the closure cap 10 depicted in Fig. 14. By means of the rim 19 being a part of the external cylindrical mantle part 37, the receptacle 12 can be re-closed even after the guarantee ring 17 has been removed. For this reason, the mouth of the receptacle 12 is provided with a protrusion 42, onto which the rim 19 snaps when the closure cap 10 is placed on the receptacle 12. The guarantee ring 17 has no role in fixing the closure cap 10 onto the receptacle 12, it only guarantees the originality of the stored material 28 indicated in Fig. 8 stored in the internal space 15 of the receptacle by means of tearable strings 12 until the guarantee ring 17 is torn off. The present embodiment is advantageously suitable for being ^• mounted onto a receptacle for storing materials 28 tending to crumble and demanding gas- tight closure. A further preferred embodiment of the closure cap 10 is shown in Fig. 2, wherein the connecting part 24 and the vibration-damper element 14 are also made of one single piece. This preferred embodiment comprises a straining insert 1 Γ. The straining insert 11 ' is produced in such a way, preferably by means of rim 26, that it can only be removed by destruction. Therefore the internal space 32 of the vibration-damper element 14, in the case of the embodiment equipped with a perforation 29 as illustrated on the tilted side view of the closure cap 10 shown in Fig. 10A, is suitable for accommodating a vapor binding material 25. In this way, this embodiment is preferably suitable for storing such a material 28 which tends to crumble and demands gas-tight closure within the internal space 15 of the receptacle 12, as the vapor binding material 25 ensures vapor binding through the perforation 29, binding all vapor appearing upon opening and closing, while continuous appearing of moisture is hindered by the gas-tight closure.

Having mounted the closure cap 10 onto the receptacle 12, straining insert 1 1 or straining insert 11 ' ensure a gas-tight closure for the stored materials 28 placed into the internal space 15 of the receptacle 12. As an impact of the circular protrusion 22 present on straining insert 11 and straining insert 11 ', an annular protrusion 21 is created on the external surface of the closure cap 10 on the sealing surface 20 of the internal cylindrical mantle part 38, creating a circular contact surface between the sealing surface 20 and the mouth of the receptacle 12. The circular contact surface ensures that if the closure cap 10 is mounted onto the mouth of the receptacle 12 no fluid can penetrate into the internal space 15 of the receptacle 12. The closure cap 10 fitted with straining insert 1 1 or straining insert 1 1 ' especially advantageously ensures gas-tight closure after an arbitrary number of removals and replacements of the closure cap 10 or after the aging of the material of the closure cap 10. As to functionality, the straining insert 1 1 " applied in the case of the two-piece closure cap 10 illustrated in Figs. 17A-19B ensures a gas-tight closure as described hereabove in addition to fixing and positioning the two separate pieces to each other.

Fig. 3 A is a three-dimensional view of an embodiment of the closure cap 10 comprising an integrated vibration-damper element. The figure shows the arrangement of the guarantee ring 17, the tag 16 facilitating its separation and the vibration-damper element 14 on the closure cap 10 from a different viewpoint than the foregoing. In Fig. 3B, the listed elements are depicted from a different viewpoint in a side view of the same embodiment. The accordionlike arrangement of the vibration-damper element 14 and the fitting of the tag 16 of the guarantee ring 17 to the external cylindrical mantle part 37 of the connecting portion 24 can be clearly observed in Figs. 3 A and 3B. Fig. 3C shows a cross-sectional side view of the same embodiment of the closure cap 10 without depicting the straining insert 1 1 or straining insert 1 1 ' . If straining insert 11 or straining insert 11 ' are not placed into the opening 27 bordered by the internal cylindrical mantle part 38 located at the top of the closure cap 10, the protrusion 21 will not appear on the sealing surface 20 of the closure cap 10, and gas-tight closure is not ensured thereby.

In Fig. 4 a cross-sectional view of an embodiment of the closure cap 10 comprising an integrated vibration-damper element 14 is shown, with a separate illustration of the straining insert 1 1. A terraced arrangement of the rim 23 ensuring non-destructive removal of the straining insert 1 1 can be clearly observed on the straining insert 1 1. It can be seen in the figure that no protrusion 21 will appear on the sealing surface 20 of the closure cap 10 without having the straining insert 1 1 placed into the opening 27. The circular protrusion 21 ensures a gas-tight pressing of the sealing surface 20 onto the mouth of the receptacle 12 in an particularly advantageous manner.

In Fig. 5 a cross-sectional view of an embodiment of the closure cap 10 comprising an integrated vibration-damper element 14 is shown in a situation, in which the straining insert 11 is placed into the opening 27 on the closure cap 10. In this case, the circular protrusion 22 located on the side of the straining insert 1 1 creates a protrusion 21 on the sealing surface 20 of the closure cap 10, which ensures a gas-tight closure when being mounted onto the receptacle 12. It is also to be noted, that the terraced arrangement of the rim 23 of the straining insert 11 fits to the edge of the opening 27.

In Fig. 6 a cross-sectional view of an embodiment of the closure cap 10 comprising an integrated vibration-damper element 14 is shown, illustrating the straining insert 1 1 separately. It is apparent that by removing the straining insert 11 , the object 13 is enabled to be introduced into the internal space 32 of the vibration-damper element 14. As the cross-sectional side view of the embodiment of the closure cap 10 integrated with a vibration-damper 14 element depicted in Fig. 7 shows, if non-destructive removal or replacement of the straining insert 11 is ensured, then storage of an object 13 placed into the internal space 32 of the vibration-damper 14 element is possible, thereby providing further options of usage for the closure cap 10. By way of example, in case of storing medicaments in the internal space of receptacle 12 closed by closure cap 10, the option of distributing medicaments without boxes - being advantageous from economic as well as environmental reasons - would be preferably enabled by storing the user's manual, patient information or any other description within the internal space 32 of the vibration-damper element 14 of the closure cap 10.

In Fig. 8 a cross-sectional view of an embodiment of the closure cap 10 comprising integrated vibration-damper element 14 is shown, mounted onto the receptacle 12, by making use of straining insert 1 1. The stored material 28 in the internal space 15 of the receptacle 12 is indicated in the figure. The stored material 28 is protected from crumbling, pulverizing as well as against physical impacts due to shaking by means of the vibration-damper element 14 by significantly constricting the moving space of the stored material 28 or by pressing down the stored material 28 not allowing any movement within the internal space 15 of the receptacle 12. The figure shows a cross-section of the closure cap 10 and the receptacle 12, wherein the tab 16 assisting the tearing away of the guarantee ring 17 and the tearable strings ensuring originality of the material stored within the internal space 15 of the receptacle 12 closed by the closure cap 10 are not depicted, but only the circular guarantee ring 17 is indicated. This figure serves to emphasize the significant functionalities of the closure cap 10 by said features and indicating the stored material 28. In Fig. 9 a cross-sectional view of an embodiment of the closure cap 10 comprising vibration- damper element 14 is shown, having the straining insert 11 removed from the opening 27 in the direction indicated by the arrow, being illustrated separately from the closure cap 10. The figure does not show the removed guarantee ring 17, nevertheless re-closure of the closure cap 10 is ensured by the snapping rim 19 irrespective of the guarantee ring 17. It is shown in the figure that by removing the straining insert 11, the object 13 placed within the internal space 32 of the vibration-damper element 14 can be removed through the opening 27 located on top of the closure cap 10. In Fig. 10A a three-dimensional view of the embodiment of the closure cap 10 comprising integrated vibration-damper element 14 is shown, indicating the perforation 29 on the lower surface of the vibration-damper element 14, said perforation 29 enabling to place a moisture absorbing material 25 into the internal space 32 of said vibration-damper element 14 . Through the perforation 29, the moisture absorbing material 25 is able to ensure dehumidification of the stored material 28 placed in the internal space 15 of the receptacle 12. The present embodiment comprising the vibration-damper element 14 equipped with the perforation 29 requires the use of a straining insert 1 . Preferably, the straining insert 1 Γ can only be removed from the opening 27 by destruction, as the moisture absorbing material 25 will properly provide its effect when it is placed in a closed space, and may only contact the stored material 28 through the perforation 29. The present embodiment can not be preferably used with straining insert 1 1 or without straining insert; placement of the moisture absorbing material 25 into an open or openable space has no significant advantage in lack of appropriate moisture control. Fig. 10B is a cross-sectional side view of the closure cap 10, without illustrating straining insert 1 1 or straining insert 11 '.

In Fig. 11 a cross-sectional side view of an embodiment of the closure cap 10 comprising an integrated vibration-damper element 14 applying straining insert 11 ' is shown, separately illustrating receptacle 12. It becomes clearly evident from the figure, that the protrusion 22 of the straining insert 1 Γ causes a protrusion 21 to appear on the sealing surface 20. By placing the closure cap 10 onto the receptacle 12, the protrusion 21 suits the inner side of the mouth of the receptacle 12 ensuring a gas-tight closure, the rim 19 snapping onto the protrusion 42 of the mouth of the receptacle 12.

In Fig. 12 a cross-sectional view of the closure cap 10 comprising an integrated vibration- damper element 14 mounted onto the receptacle 12 is shown, without representing straining insert 11 or straining insert 11 '. The connecting part 24 of the closure cap 10 is fixed to the mouth of the receptacle 12.

In Fig. 13 a cross-sectional view of an embodiment of the closure cap 10 comprising an integrated vibration-damper element 14 without representing straining insert 11 or straining insert 1 1 ' is shown, indicating the compressed state of the vibration-damper element 14 by means of a dashed line, and indicating an H difference from the non-compressed state of the vibration-damper element 14. The resilient compressibility of the vibration-damper element 14 ensures to prevent crumbling, pulverizing of the stored material 28, and increases its resistance against any physical shacking impacts.

In Fig. 14 a cross-sectional side view of an embodiment of the closure cap 10 comprising an integrated vibration-damper element 14 is shown, mounted onto the receptacle 12, illustrated without straining insert 11 or straining insert 11 '. The tag 16 inclines as an impact of the protrusion 42 of the mouth of the receptacle 12. Inclination of the tab 16 promotes easier separation of the guarantee ring 17, as a result of which the closure cap 10 becomes removable from the mouth of the receptacle 12. By means of the snapping rim 19, the closure cap 10 can be reapplied onto the mouth of the receptacle 12 even after removal of the guarantee ring 17. In Fig. 15 A, a three-dimensional drawing of an embodiment of the closure cap 10 comprising an integrated vibration-damper element 14 is shown with a closed vibration-damper element 14, and the guarantee ring 17 is depicted in Figure 15B, being separated from the closure cap 10. By removing the guarantee ring 17, the tearable strings 18 are broken into two pieces, portion 33 remains on the guarantee ring 17, while portion 34 remains on the closure cap 10. The tearable strings 18 ensure originality of the stored material 28 placed within the internal space 15 of the receptacle 12 closed by the closure cap 10.

In Fig. 16 a cross-sectional view drawing of an embodiment of the closure cap 10 is shown mounted onto the receptacle 12 comprising an integrated vibration-damper element 14, with straining insert 1 Γ and without the removed guarantee ring 17. After the removal of the guarantee ring 17, the closure cap 10 can be refixed onto the mouth of the receptacle 12, i.e. protrusion 42, by means of the remaining snapping rim 19, and a gas-tight closure is further ensured by the use of the straining insert 1 1 '. In this way, preferably, the functionality of the closure cap 10 is not altered by the removal of the guarantee ring 17, only the originality of the stored material 28 in the receptacle 12 is no longer ensured thereby. In Fig. 17A a side view drawing of a further embodiment of the closure cap 10 is shown, wherein the vibration-damper element 14 and the connecting part 24 of the closure cap 10 are formed in separate pieces. In Fig. 17B a cross-sectional side drawing of the same embodiment of the closure cap 10 is shown taken along plane A-A indicated in Fig. 17A, illustrating that in the present embodiment the separate pieces of the closure cap 10 are held together by the straining insert 1 1 ". In the present embodiment, the upper part of the vibration-damper element 14 is provided with a connecting neck portion 44 abuttingly connected to the connecting part, and being pressed against the connecting part by means of a straining insert. The straining insert 1 1 " is configured in such a way that the diameter of the top of the straining insert 1 1 " is larger than the external diameter of the side portion 39, so as to ensure that the straining insert 11 " does not slide too far into the closure cap 10, as well as to position the top of the connecting part 24 and the upmost rim of the connecting neck portion 44 of the vibration-damper element to even heights. The connection between the internal cylindrical mantle part 38 and the vibration-damper element 14 is in this case an abutting connection. In the present embodiment, a protrusion 22 of the straining insert 11 " is suitable for ensuring a gas-tight closure as in the case of the above-detailed appropriate embodiments, with the difference that the protrusion 22 in this case exerts its impact through two layers of materials (the material of the connecting neck portion 44 and the material of the internal cylindrical mantle part 38). Accordingly, the protrusion 22 of the straining insert 11 " creates protrusion 43 on the connecting neck portion 44, as a result of which the protrusion 21 is evolving on the sealing surface 20 of the internal cylindrical mantle part 38 of the connecting portion 24 in a manner similar to the impact mechanism of the one-piece cap. In Fig. 18 A a side view drawing of the two-piece embodiment of the closure cap 10 is shown, while in Fig. 18B a cross-sectional side view drawing taken along the A-A plane indicated in Fig. 18A is shown, separately representing the straining insert 1 1 ". The figures illustrate the positioning impact of the straining insert 1 1 ", as well as indicate that the use of straining insert 1 1 " ensures that the entire closure cap 10 can be handled as one unit, and the gas-tight closure is ensured in a manner as described hereabove. It is furthermore clearly evident from the figure that the straining insert 1 1 " no longer directly supports the sealing surface 20 constituting the sidewall of the opening 27, but onto the internal surface of the connecting neck portion 44 of the vibration-damper element 14.

In Fig. 19A a side view of the two-piece embodiment of the closure cap 10 is shown, while in Fig. 19B a cross-sectional side view drawing taken along plane A-A indicated in Fig. 18A is shown, and the respective separate pieces are shown separately. The figures demonstrate the order of assembly of the two-piece closure cap 10. Into the opening 27 bordered by the connecting part 24 fits the vibration-damper element 14 having a connecting neck portion 44 in its upper part. Into the opening defined by the inner surface of the connecting neck portion 44 fits the straining insert 11 " pressing the connecting neck portion 44 to the internal cylindrical mantle part 38 of the connecting portion 24. The method of manufacturing is described herebelow with regard to an especially preferred embodiment of the inventive closure cap integrated with a vibration-damper element. In the course of this method, a connecting part and a pre-form part of the vibration-damper element in its initial manufacturing phase are made from two different pieces out of materials of different viscosity. Both pieces are made of polyethylene, preferably of a low and a high density version thereof. Instead of the viscosity, these materials are characterized by their flow-indices, being inversely proportional to viscosity. The connecting portion is made of a material optimized for injection-molding process, by way of example it may be HDPE (high density polyethylene) or LDPE (low-density polyethylene), the flow-index of the applied material is typically approx. 2-50 g/lOmin. The pre-form part is preferably made of LDPE material optimized for blowing (hereinafter referred to as blow-material), nevertheless by means of injection-molding as well, the flow-index of which material is typically approx. 0,3 g/lOmin. This means that the blow-material has a higher viscosity than the injection-molding material, preferably at least by one order of magnitude. The method consists of the following steps: first, the connecting part is melted and injection- molded at an initial temperature higher than 200° C, in the course of which the applied material cools within the mold, and thereby attaining the geometry of the form-setting part of the mold. The pre-form part is also made by this process, but does not remain in the form- cavity of the mold until fully cooled, but when cooled to 110-130° C, it is removed into a form-setting cavity used for blowing in the same mold. In this mold, the partly cooled connecting part is already present in the appropriate place, the thinned rim of which is melted by the heat energy stored within the excess material formed on the pre-form part during the injection-molding process, thereby the connecting part and the pre-form part are molten together, i.e. become an integral piece. Meanwhile, a high-pressure air used in the form-setting cavity effects the yet plastic pre-form part to press into the mold forming the resilient accordion-like part; thereby an accordion-like shaped vibration-damper element is formed. The final shape of the vibration-damping element having resilient characteristics is achieved by cooling in the mold, which by melting and cooling together with the connecting part becomes an integral piece therewith. As both applied materials are preferably polyethylene, their appropriate unification is easy to be ensured.

In the course of manufacturing, both pieces of the closure cap may be colored. It is typically advisable to color the connecting part having an opal and transparent natural color. The vibration-damper may be fitted with a perforation in order to provide for appropriate applicability of the aforementioned moisture absorbing material, and the straining insert is also introduced therein.

The production process of the embodiments of the closure cap 10 integrated with the vibration-damper element 14 shall be presented with reference to additional figures. In Fig. 20A a three-dimensional drawing of the embodiment of the closure cap 10 integrated with a vibration-damper element 14 is shown, in a manufacturing state, wherein the vibration- damper element 14 had not yet attained its final form; the vibration-damper element 14 is formed from pre-form part 35. The pre-form part 35 will obtain its final shape by means of high-pressure air blow in a following step. The blowable pre-form part 35 constitutes already an integral unit with the connecting part 24 of the closure cap 10, their unification have already taken place by means of melting them together. This producing state is followed by a further forming step; however, in this phase the closure cap 10 possesses all respective characteristic features less vibration-damping. In Fig. 20B a side view drawing of the closure cap 10 is shown in the detailed state of production illustrating the blowable pre-form part 35. In Fig. 20C a cross-sectional side view drawing of the closure cap is shown without the straining insert 11, 1 , 1 1 ".

In Fig. 21 a cross sectional side view drawing of the closure cap 10 is shown, wherein the blowable pre-form part 35 is indicated by a dashed line. The final resilient form of the vibration-damper element 14 is also indicated, attainable by means of high pressure gas blow, as a result of which the pre-form part 35 takes the shape of the vibration-damper mold having been placed around it in this step. The direction of the current of the high pressure gas 36 is indicated in the figure by small arrows. For this shaping action it is not required that the closure cap 10 is in a plastic state.

Three different production phases of the closure cap 10 are demonstrated in side view in Figs. 22A-C, in bottom view in Figs. 23A-C as well as in Figs. 24A-C respective cross-sectional side views taken along plane A-A of Figs. 23A-C are shown. The connecting part 24 of the closure cap 10, as the firstly produced element can be seen in Fig. 22A, as well as the manufacturing state of the closure cap 10 in Fig. 22B, wherein the blowable pre-form part 35 is already connected, and the final state of the closure cap 10 in Fig. 22C, wherein the vibration-damper element 14 has already obtained its final shape. In Figs. 22B and C, there is demonstrated an excess material 45 placed onto the pre-form part 35, required for connecting the pre -part part 35 onto the connecting part 24 thereby, wherein the heat necessary for melting the thinned rim of the connecting part 24 is stored. In the course of the melting- together action, the pre-form part 35 with a temperature of 110-130° C is connected to the cooled connecting part 24. The above listed procession states are demonstrated in bottom view in Figs. 23A-C, and the course of procession can be followed on these figures. In Fig. 23A the connecting part 24 is shown arranged with an opening in its middle, into which opening the straining insert 1 1, 11 ',11 " can be placed, in Fig. 23B the bottom of the already connected pre-form part 35, while in Fig. 23C the lower part of the vibration-damper element 14 can be observed. Figs. 24A-C show the cross sectional side view drawings of the respective courses of processing, i.e. in Fig. 24A the initial state, in Fig. 25B the connected pre-form part 35, and in Fig. 25 C the vibration-damper element 14 with its final state can be seen.

A processing phase of the closure cap 10 is illustrated in Fig. 25 A in side view and in a cross- sectional side view taken along plane A-A of Fig. 25A in Fig. 25B, in which the connecting part 24 and the pre-form part 35 of the closure cap 10 are melted together. In Fig. 25C an enlarged view of the section encircled in Fig. 25B is shown, i.e. the thinned rim of the connecting part 24 meltable during its unification with the pre-form part, and on the pre-form part 35 the excess material 45 is depicted arranged for storing the heat sufficient for melting the thinned rim of the connecting part 24, which are connected to each other after the melting process as indicated in Fig. 25 C.

The one-piece configuration of the closure cap 10 promotes avoiding separation or loss of the vibration-damper element 14 during its use, which is often the case with separately manufactured vibration-damper elements.

The invention is of course not limited to the preferred embodiments disclosed in detail, but further variations, modifications and developments are possible within the scope defined by the claims. Beside the presented embodiments, by way of example, the application of a ring shaped straining insert is also possible, preferably equipped with a bracing, that is configured to create an all-around protrusion on the sealing surface to ensure gas-tight closure of the closure cap, however, as opposed to the presented embodiments, it only contains the ring corresponding to the all-round protrusion of the straining inserts of the presented embodiments. The thus obtained tightening-ring can be strengthened by means of an insert of any shape, for example by cross-shaped or polygon-shaped inserts, moreover a disc-shaped straining insert is preferably applicable, which is practicably a material-filled ring. An arbitrarily arranged disc- shaped ring ensures the internal space of the vibration-damper element to be a closed space, furthermore it may be fitted with any arbitrary tool to provide for non-destructive removal, or if non-destructive removal is intended to be prevented, then it may be fitted with a protection necessary therefor.

In case of a two-piece closure cap, instead of the abutting and straining-insert-positioned connection between the connecting part and the connecting neck portion, any other connection can be also imagined, where fitting is promoted by the application of appropriately arranged projections and notchings.

Further configuration possibilities of the guarantee ring and the tab facilitating its separation are also possible.
