Technical Field
[1] The present invention relates to a vessel cap for opening and closing a vessel inlet, and a vessel having the same. Background Art
[2] FIG. 1 is a sectional view of a vessel inlet in accordance with the conventional art.
[3] Generally, a beverage vessel such as lactobacillus drink, etc. is provided with a sealing member 114 attached onto a vessel inlet 102, so that contents stored in a vessel 104 can maintain a sealed state without being leaked to outside. In order to prevent the sealing member 114 from being damaged due to an external impact or contact with an object, a vessel cap 100 is disposed to cover the vessel inlet 102.
[4] The vessel cap 100 is formed in a cylindrical shape having a closed upper side. On an inner circumferential surface of the vessel cap 100, formed is a locking jaw 110 locked by a locking rib 108 formed on an outer circumferential surface of the vessel inlet 102. A handgrip 112 held by a user to pull the vessel cap 100 from the vessel inlet 102 is formed at the vessel cap 100.
[5] After detaching the vessel cap 100 from the vessel inlet 102 by pulling the handgrip
112, the sealing member 114 is partially or entirely removed or detached from the vessel inlet 102. Then, contents stored in the vessel 104 is discharged out through the vessel inlet 102.
[6] However, the conventional vessel cap has the following problems. First, after detaching the vessel cap from the vessel, the sealing member attached onto the vessel inlet for sealing has to be removed by a user's hand in a tear-away manner, or by an additional tool such as a knife. This causes inconvenience when using the vessel cap.
[7] Furthermore, when removed by a user's hand, the sealing member is not easily detached from an edge portion of the vessel inlet due to a strong adhesive force with the edge portion. Accordingly, the user has to again remove the sealing member in a tear-away manner, which may cause sanitary problems due to contact between the user's hand and the vessel inlet.

[54] Hereinafter, a vessel cap and a vessel having the same according to the present invention will be explained in more detail with reference to the attached drawings.
[55] As shown in FIG. 2, a vessel cap 2 according to the present invention comprises: a body 16 having a space therein, the body 16 being mounted to a vessel inlet 12 to which a sealing member 20 is attached and through which contents inside a vessel 10 are discharged out; a pressing plate 40 disposed in the body 16 so as to be movable in upper and lower directions; a connection portion 46 connected between an outer circumferential surface of the pressing plate 40 and an inner circumferential surface of the body 16, so that the pressing plate 40 can move in upper and lower directions; and one or more cutters 42 formed in a circumferential direction of a lower edge of the pressing plate 40, for penetrating the sealing member 20 when the pressing plate 40 is pressed, and cutting the sealing member 20 when the body 16 is rotated.
[56] The sealing member 20 for storing contents of a liquid state inside the vessel 10 by sealing the vessel inlet 12 is attached to the vessel inlet 12 through which the contents are discharged out. Preferably, the sealing member 20 is formed of material such as paper or an aluminum thin plate that can be easily removed by a knife, etc.
[57] The body 16 is formed in a cylindrical shape, and a plurality of concave-con vexed protrusions 28 for facilitating the vessel cap 2 to be rotated by a user's hand are formed on an outer circumferential surface of the body 16. A mounting portion detachably mounted to the vessel inlet 12 is formed at a lower portion of the body 16.
[58] The mounting portion serves to couple the vessel cap 2 to the vessel inlet 12 by various manners such as a screw manner or a snap manner.
[59] A skirt portion 71 for fixing the vessel cap 2 to the vessel inlet 12 so as to certify whether the vessel cap 2 has been opened or not is formed at a lower end of the body 16. When the vessel cap 2 is opened, the skirt portion 71 is torn away to be detached from the vessel inlet 12.
[60] As shown in FIGS. 3 and 5, the cutter 42 may include one or more supporting portions 54 formed at a lower edge of the pressing plate 40; a lower end portion 42c sharply formed at a lower end of the supporting portion 54, for penetrating the sealing member 20 by downwardly moving when the pressing plate 40 is pressed; and a front end portion 42a and a rear end portion 42b formed at least one of a front end and a rear end of the supporting portion 54, for cutting the sealing member in a circular shape by being rotated with a contact state to an inner circumferential surface of the vessel inlet 12 when the body 16 is rotated.
[61] Here, the cutter 42 may have any shape or sectional shape as long as the cutter 42 having been inserted into the sealing member 20 can cut the sealing member 20 in a direction (R) that the body 16 is detached from the vessel inlet 12. The cutter 42 may have various modifications.
[62] The vessel cap 2 according to the present invention may further include a cutting restriction means to restrict a cut-degree of the sealing member 20 by the cutter 42 according to rotation of the body 16 when being detached from the vessel inlet 12.
[63] Also, the vessel cap 2 according to the present invention may further comprise a locking means to allow the sealing member 20 to be partially cut by the cutter 42 and then to be automatically lifted from the vessel inlet 12 according to rotation of the body 16 when being detached from the vessel inlet 12.
[64] In the present invention, the cutting restriction means and the locking means may be variously implemented according to a coupling manner between the vessel cap and the vessel, etc. Hereinafter, the configurations will be explained in more detail with reference to the attached drawings.
[65] As shown in FIG. 3, the cutting restriction means for restricting cutting of the sealing
member 20 is provided with a non-cutting region (θn) having a certain angle based on a rotation shaft of the vessel cap 2 so that a part of the sealing member 20 detached from the vessel inlet 12 can not be cut by the cutter 42 being rotated.
[66] When an angle between the front end portion 42a and the rear end portion 42b of the cutter 42 is 'α' based on a rotation direction of the body 16, the cutting restriction means is implemented so that a rotation angle (θc) of the front end portion 42a of the cutter 42 can satisfy the following, θc<(360°-α). Here, the rotation direction of the body 16 may be defined as a direction to be detached from the vessel inlet 12.
[67] The cutter 42 may be implemented in one or plurality in number. Referring to FIG. 4, when the cutter 42 is implemented in plurality in number, the 'α' may be defined as an angle between the front end portion 42a of the first cutter 42 and the rear end portion 42b of the last cutter 42 based on the rotation direction of the body 16.
[68] The cutting restriction means may have various configurations according to a coupling manner between the body 16 and the vessel inlet 12.
[69] As shown in FIGS. 6 and 7, will be explained a screw manner between the body 16 and the vessel inlet 12, that is, a female screw portion 35, a mounting portion is formed at an inner circumferential surface of a lower end of the body 16 so as to be screw- coupled to a male screw portion 12a formed on an outer circumferential surface of the vessel inlet 12. Here, the cutter for cutting the sealing member 20 may be sharply formed only at the front end portion 42a with consideration of a rotation direction of the body 16 based on an open direction of the body 16 from the vessel inlet 12.
[70] Firstly, the cutting restriction means may be implemented so that the vessel cap 2 can be detached from the vessel inlet 12 when the body 16 is rotated by a rotation angle(θc) of the front end portion 42a of the cutter 42.
[71] That is, the female screw portion 35 screw-coupled to the male screw portion 12a of the vessel inlet 12 may be formed so as to be detached from the male screw portion 12a of the vessel inlet 12 by controlling a coupling angle with the male screw portion 12a, before a cut-out portion cut by the cutter 42 is in an angle of 360°.
[72] On the contrary, the male screw portion 12a formed at the vessel inlet 12 may be formed so as to be detached from the female screw portion 12a of the vessel inlet 12 by controlling a coupling angle with the female screw portion 35, before a cut-out portion of the female screw portion 35 screw-coupled to the male screw portion 12a cut by the cutter 42 is in an angle of 360°.
[73] Secondly, the cutting restriction means may be implemented that the female screw portion 35 may be formed so that a lower end 42c of the cutter 42 can move to an upper side of an upper surface of the sealing member 20 when the body 16 is rotated by a rotation angle (θc) of the front end portion 42a of the cutter 42 so as to detach the vessel cap 2 from the vessel inlet 12.
[74] That is, as shown in FIG. 8, the female screw portion 35 screw-coupled to the male screw portion 12a of the vessel inlet 12 may be formed so that the lower end 42c of the cutter 42 can move to an upper side of an upper surface of the sealing member 20 before a cut-out portion cut by the cutter 42 be in an angle of 360° by controlling a lifted height (H) of the body 16 by being rotated.
[75] On the contrary, the male screw portion 12a formed at the vessel inlet 12 may be formed so that the lower end 42c of the cutter 42 can move to an upper side of an upper surface of the sealing member 20 before a cut-out portion cut by the cutter 42 is in an angle of 360° by controlling a lifted height (H) of the body 16 by being rotated.
[76] Next, referring to FIG. 15, will be explained a snap manner between the body 16 and the vessel inlet 12, e.g., a case that the mounting portion is composed of a locking jaw 16a formed at an inner upper end of the body 16 and adhered to an upper end of the vessel inlet 12 having the sealing member 20 attached thereto, and a locking groove 16b formed at an inner circumferential surface of a lower end of the body 16, and locked by a locking jaw 12b formed on an outer circumferential surface of the vessel inlet 12. Here, the cutter 42 may be formed so that both the front end portion 42a and the rear end portion 42b thereof can be sharply formed so as to cut the sealing member 20, since it is not influenced by rotation of the body 16 in two directions differently from the screw manner.
[77] The cutting restriction means may be implemented to restrict a cut angle of the sealing member 20 by restricting a rotation angle of the cutter 42 by restricting a rotation angle of the body 16.
[78] Firstly, as shown in FIGS. 15 and 16, the cutting restriction means may include one or more rotation restriction protrusions 16d formed at the body 16 so as to be locked by one or more rotation angle restriction jaws 12d formed at the vessel inlet 12 in order to restrict a rotation angle of the body 16 at the vessel inlet 12 in a circumferential direction.
[79] The rotation angle restriction jaws 12d and the rotation restriction protrusions 16d may be respectively implemented in plurality in number so as to restrict a rotation angle of the body 16, and may be long formed in a circumferential direction by a certain angle based on rotation of the body 16.
[80] Here, the rotation angle restriction jaws 12d may be integrally formed with the vessel inlet 12, or may be implemented as an additional member to be combined with the skirt 71.
[81] Secondly, as shown in FIG. 17, the cutting restriction means may be implemented as one or more rotation angle restriction jaws 12c formed on an inner circumferential surface of the vessel inlet 12 so that the cutter 42 can restrict a rotation angle of the body 16 in a circumferential direction of the vessel inlet 12.
[82] Here, the cutter 42 is provided with a non-cutting region (θn) for restricting cutting of the sealing member 20 by restricting a rotation angle of the body 16. [83] Thirdly, as shown in FIG. 18, the cutting restriction means may be implemented so that a part of the sealing member 20 can not be cut by the cutter 42, or may be further provided with a member 20a attached thereto and formed of a non-cutting material. [84] Since it is preferable to lift the sealing member 20 cut by the cutter 42 when the vessel cap 2 is detached from the vessel inlet 12, the vessel cap 2 may further include a locking means. [85] The locking means may have various configurations to lift a cut-part of the sealing member 20 when the vessel cap 2 is detached from the vessel inlet 12. [86] As shown in FIG. 10, the locking means may include a rod 60 downwardly extending from the center of a lower surface of the pressing plate 40; and a locking protrusion 62 formed at the end of the rod 60, for penetrating the sealing member 20 when the pressing plate 40 is pressed, and lifting the sealing member 20 having been locked when the body 16 is detached from the vessel inlet 12. [87] The end of the rod 60 may be sharply formed so as to easily penetrate the sealing member 20. The locking protrusion 62 may be formed so as to easily bend the sealing member 20 for facilitation of locking after penetrating the sealing member 20. [88] As shown in FIGS. 11 to 14, the locking means may be implemented as a locking portion 66 formed at the end of the cutter 42, for cutting the sealing member 20 and locking the cut sealing member 20. [89] The locking portion 66 may be implemented as a supporting jaw 66a formed at the end of the cutter 42, for supporting a lower surface of the sealing member 20. [90] The supporting jaw 66a may be formed to be parallel to the surface of the sealing member 20, or may be inclined towards upside of the sealing member 20. [91] The supporting jaw 66a of the locking portion 66 may be formed to be inclined based on a rotation angle of the body 16 so that the cut sealing member 20 can be lifted up with consideration of a rotation angle of the body 16. [92] Operation of the vessel cap and the vessel having the same according to the present invention will be explained in more detail. [93] As shown in FIGS. 6, 15, etc., the vessel cap 2 of the present invention maintains a coupled state to the vessel before being used. [94] When a user is to discharge contents stored in the vessel by rotating the body 16 of the vessel cap 2, the sealing member 20 is penetrated by the cutter 42 by pressing the pressing plate 40. Then, the user rotates the body 16 of the vessel cap 2, thereby cutting a part of the sealing member 20 by the cutter 42. [95] Here, by the various cutting restriction means, the cutter 42 performs its cutting function with allowing a part of the sealing member 20 not to be cut. Referring to FIG.
8 or 20, as the user lifts up the vessel cap 2, the sealing member 20 is lifted up from the vessel inlet 12 by the locking means.
[96] The pressing plate 40, the connection portion 46, and the cutter 42 may be partially formed on an upper surface 16c of the body 16, not entirely.
[97] As shown in FIGS. 19 to 23, the pressing plate 40 may be connected to the upper surface 16c of the body 16 by the connection portion 46, thereby constituting a part of the upper surface 16c of the body 16.
[98] Here, the pressing plate 40 may be formed to have not only a circular shape but also various shapes such as a rectangular shape.
[99] Whether the pressing plate 40 includes a central portion of the upper surface 16c of the body 16 or not is determined according to the locking means. If the locking means is implemented as shown in FIGS. 19 to 21, the pressing plate 40 has to include the central portion of the upper surface 16c of the body 16.
[100] Meanwhile, when the pressing plate 40 is formed, it may be unnecessarily pressed arbitrarily, or by an impact.
[101] In order to solve this problem, the vessel cap 2 may be further provided with various configurations to prevent not only the protrusion jaw 17 protruding to an upper side of the body 16 but also the pressing plate 40 from being exposed out. As shown in FIGS. 24 to 26, the vessel cap 2 may be further provided with a supplementary cap 1 for covering the pressing plate 40.
[102] As shown in FIGS. 24 and 25, the supplementary cap 1 may be detachably coupled to the body 16 in a screw manner or in a snap manner so as to cover the pressing plate 40.
[103] As shown in FIG. 26, the supplementary cap 1 may be coupled to the body 16 in a hinge manner.
[104] The vessel cap 2 may be further provided with an outer cap (not shown) such as a child-resistant closure (CRC) for preventing a child from detaching the vessel cap 2 from the vessel by rotating the body 16 only when force is applied to the body 16.
[105] It will also be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
