Title of Invention: DRINK CONTAINER AND MOUNTING

MEMBER

Technical Field

[0001] The present invention relates to a drink container and a mounting member attached to the drink container. Background Art

[0002] When being sold, for example, in a convenience store, containers, such as drink cans and PET bottles, filled with drink are placed to stand upright on a display device put, for example, in a display case. There, the display device as described above is arranged, for example, in a sloping state so that each container may move frontward in the display case due to its own weight. When one container at a front side (in the front row) is taken out, other containers following that container move toward the front side due to their own weight.

Here, for example, a plastic flat plate is provided, because of good sliding of containers, to a part on which the containers are placed in the display device. Meanwhile, a display device in which a large number of rotatable rollers are arranged has become available in recent years (for example, refer to patent literature 1). Additionally, although containers are supplied from a back side of a display device in general, there is proposed a display device allowing containers to be supplied from a front side, and allowing a container, which has moved backward, to move to the front side again so as to be displayed (for example, refer to patent literature 2). That is, there is proposed a display device in which a container supplied from a front side makes a U-turn and returns. Furthermore, with regard to a container, there has been proposed a can having inside concave portions and vertical ribs alternately formed, in a circumferential direction, in an inner circumferential wall of an annular convex portion formed on a bottom of the can (for example, refer to patent literature 3).

[0003] An outer face of a container is provided with a mark, such as a trade name or a trademark, for differentiating a product from other products. If this mark does not face a side from which a purchaser takes out the container, the purchaser finds it difficult to identify the product, and also the product does not look good when being displayed. For this reason, it is preferable that marks on displayed containers face a predetermined direction which is, for example, a front direction or the like.

[0004] As a conventional technique described in the official gazettes, there has been proposed a display method (for example, refer to patent literature 4) in which: on an upper face of a sloping shelf plate on which containers are placed, a rod- shaped guide ridge is provided to extend in a sloping direction of the shelf plate; on a bottom portion of each container, a concave fitting portion is provided to connect a position directly under a mark to a position directly under a face opposite to a face where the mark is attached; and the container is displayed by use of this guide ridge and this concave fitting portion. In this display method, plural containers are aligned in a front-back direction by having the concave fitting portions fit to the guide ridge with each of those containers put in such a position that the mark faces frontward. As a result, the containers are displayed with the marks facing frontward. Citation List

Technical Problem

[0006] In Patent literature 4 mentioned above, by performing display of the containers with the concave fitting portions being fit to the guide ridge, the marks are reliably faced frontward. In this invention, however, a supplier of the containers is required to fit the concave fitting portions to the guide ridge every time the supplier puts the container on a display device, and this makes displaying work of the containers troublesome. Additionally, in a case where the mark is formed on only one part of each of the containers, it is feared that there may occur a display failure in which some of the containers are displayed with the marks facing backward. Additionally, in a store or the like, such as a convenience store, where a large number of drinks are sold, work of supplying the containers in a way to make the containers face the same direction is very extensive.

[0007] The main object of the present invention is to provide a drink container and the like that enable a mark thereon to face a predetermined direction even if the mark faces a random direction when the container is displayed so as to stand upright in a display device. Solution to Problem

[0008] In order to attain the object there is provided a drink container to which a present invention is applied, including: a bottom portion that has a contact portion being in contact with a placement face; and a side portion that is provided above the bottom portion and on which an identification mark for differentiating a product from other products is applied at a predetermined portion. The contact portion of the bottom portion has a first region having a first friction coefficient and a second region having a second friction coefficient larger than the first friction coefficient, the second region being provided on an opposite side to a side where the identification mark is provided.

[0009] Here, the first region and the second region are formed by application of a material giving a different friction coefficient on at least any one of the first region and the second region. In addition, the first region and the second region are formed by adhering any one of a sticker and a tape giving a different friction coefficient, to at least any one of the first region and the second region. Further, the first region and the second region are formed by giving an unevenness portion to at least the second region.

[0010] From another aspect of the present invention, there is provided a drink container to which the present invention is applied, including: a bottom portion; and a side portion that is arranged above the bottom portion and on which an identification mark is applied for differentiating a product from other products. A center of gravity of the drink container is positioned toward a side where the identification mark is provided when the bottom portion is placed on a horizontal plane.

[0011] Here, the drink container is formed so that the center of gravity may be positioned toward the side where the identification mark is provided, by additionally attaching a member. In addition, the member has larger specific gravity than that of a material forming the bottom portion and a material forming the side portion. Further, the member is attached to the bottom portion of the drink container.

[0012] From further aspect of the present invention, there is provided a drink container to which the present invention is applied, which is a drink container sliding, in a downward direction, on a sloping surface provided in a display device and being to be displayed. The drink container includes: a drink container body that has a bottom portion and a side portion on which an identification mark for differentiating a product from other products is applied, and that is to be filled with drink; and a rotation portion that rotates the drink container body so that the identification mark may face the downward direction when the drink container body slides, in the downward direction, on the sloping surface in a state where the bottom portion is in contact with the sloping surface.

[0013] Here, the rotation portion is attached to the drink container body, and is formed of a setting member setting a center of gravity of the drink container body to be positioned toward a side where the identification mark is applied. In addition, the setting member has larger specific gravity than that of a material forming the drink container body. Further, the setting member is attached to the bottom portion of the drink container body. Moreover, the bottom portion includes, at a contact portion with the sloping surface, a first region and a second region respectively having friction coefficients different from each other, and the rotation portion is formed of the first region and the second region included in the bottom portion.

[0014] In case of taking the present invention as a mounting member, the mounting member to which the present invention is applied is a mounting member mounted on a drink container having a bottom portion and a side portion that is arranged above the bottom portion and that an identification mark for differentiating a product from other products is applied thereon. The mounting member includes a main body that is to be fitted into the drink container. When the mounting member is mounted on the drink container in a state of having a predetermined positional relationship with the drink container, the mounting member causes a center of gravity of the drink container to be displaced toward a side where the identification mark is applied.

[0015] Here, the mounting member at least includes: the main body that is a tubular shape and that is fitted into any one of an upper portion of the drink container and the bottom portion; and a displacement member that displaces a center of gravity of the main body from an axial center of the main body. In addition, the displacement member is provided inside of the main body formed into the tube.

[0016] From a furthermore aspect of the present invention, there is provided a mounting member to which the present invention is applied, which is mounted on a bottom portion included in a drink container further including a side portion that is arranged above the bottom portion and on which an identification mark for differentiating a product from other products is applied. The mounting member includes: a first region having a first friction coefficient; and a second region having a second friction coefficient larger than the first friction coefficient, the first region and the second region being provided on an opposite side to a side mounted on the bottom portion.

Advantageous Effects of Invention

[0017] It is possible to provide a drink container or the like that enables the mark to face a predetermined direction even if the mark faces a random direction when the container is placed to stand upright and displayed in the display device.

[0019] Best modes for carrying out the invention will be described below in detail with reference to the accompanying drawings.

- First exemplary embodiment -

FIG. 1 (FIGs. IA and IB) is a view showing a schematic configuration of a display device according to the first exemplary embodiment of the present invention.

As shown in FIG. IA, a display device 30 according to the first exemplary embodiment includes a placement unit (placement face) 31 on which containers (drink containers) 20 with drink filled therein are placed, and guides 32 that form moving routes (transportation routes) of the containers 20, and that guide movement of the containers 20. The display device 30 also includes a regulation plate 34, a part of which is formed transparently, which is arranged along one side of the placement unit 31 and which stops movement of the containers 20. Here, each of the guides 32 is fixed to the placement unit 31 by having both ends thereof inserted into openings 33 formed in the placement unit 31. Additionally, although a can shaped as a cylinder is illustrated as an example of each of the containers 20, a container made of resin such as a so-called PET bottle, a so-called bottle can having a cap, or the like may also be used.

[0020] The display device 30 is, as shown in FIG. IB, put inside a display case 10 installed in a convenience store, a super market or the like. This display case 10 includes a case main body unit 1OA formed into a rectangular parallelepiped shape, and doors 1OB provided so as to be openable and closable with respect to this case main body unit 1OA, which form a main part of the display case 10.

Here, the display device 30 is placed on a shelf (not shown in the figure) provided to the display case 10. On this occasion, the display device 30 is placed so that the side where the regulation plate 34 is provided may be located at the side where the doors 1OB are provided. Additionally, the display device 30 is placed so that the side where the regulation plate 34 is provided may be positioned at a lower level than a side opposite to the side where the regulation plate 34 is provided. By this configuration, the placement unit 31 of the display device 30 is arranged in a downward sloping state from a back side of the display case 10 toward a front side thereof (a side of a taken- out portion) from which the containers 20 are taken out. [0021] Here, the display case 10 in the first exemplary embodiment also has a door (not shown in the figure) provided on the back side thereof, whereby the back side becomes also openable. The containers 20 are supplied to the display device 30 from this back side. That is, the display case 10 has a configuration where a supplying portion for the containers 20 is provided at the back side of the display case 10, and at the back side of the display device 30. There, the containers 20 having been supplied move (slide) on the placement unit 31 toward the doors 1OB. That is, the containers 20 move toward purchasers who purchase the containers 20. Note that, in this description, the side where the doors 1OB are provided is sometimes referred to as a front side (frontward), whereas the side opposite to the doors 1OB is sometimes referred to as a back side (backward). Additionally, a width direction (a direction orthogonal to a direction in which the containers 20 move) of the display case 10 is sometimes referred to as a lateral direction, or as a width direction.

[0022] FIG. 2 (FIGs. 2A and 2B) is a view for explaining the containers 20 according to the first exemplary embodiment.

The container 20 shown in FIG. 2A includes a bottom portion 21 formed into a disk shape, a side portion 22 upwardly extending from the outer circumference edge of the bottom portion 21 and a lid portion 24 attached on an upper part of the side portion 22, and the container 20 is formed into a cylindrical shape. Additionally, the container 20 includes an annular projecting portion 211 provided on the bottom portion 21. The annular projecting portion 211 annularly projects toward an outside of the container 20 (a direction away from the bottom portion 21). Further, the container 20 has an identification mark 23 for differentiating a product from other products, such as a product name, or a trademark. The identification mark 23 is applied on a specific portion of the side portion 22 as a part of an outer face. Furthermore, the container 20 has a weight 212 provided on the bottom portion 21. Note that the bottom portion 21 and the side portion 22 may be taken as a drink container body which is to be filled with drink. The weight 212 may be taken as a setting member that sets the center of gravity of the drink container body to be positioned toward a side where the identification mark 23 is applied.

[0023] Note that, a material of the containers 20 is not particularly restricted as long as the material is resistant to alcoholic beverages such as beer, or soft drinks such as juice. For example, a metal such as aluminum or steel, resin such as PET (polyethylene terephthalate), glass, or the like may be used.

Additionally, shapes and types of the containers 20 are also not particularly restricted. Examples of the containers 20 include so-called two-piece cans (DI cans), three-piece cans, PET bottles, glass bottles and cans with thread (so-called bottle cans).

[0024] The weight 212 is made of a material having larger specific gravity than the material (for example, aluminum) of the container 20, and the material of the weight 212 is, for example, a metal such as lead. The weight 212 is provided so as to be in contact with the inner side face of the annular projecting portion 211. Further, the weight 212 is provided at an eccentric position with respect to the center of gravity (or the center) of the container 20. Furthermore, the weight 212 is provided on the same side as the side where the identification mark 23 is provided. By this configuration, the container 20 according to the first exemplary embodiment is configured so that the center of gravity may be positioned toward the side where the identification mark 23 is provided in the case where the container 20 is placed on the horizontal plane. The weight 212 may be attached to the container 20 with, for example, adhesion.

[0025] With reference to FIG. 2B, the movement of the container 20 in the display device 30 will be explained.

The container 20 placed on the back side of the display device 30 and having started the movement toward the front side thereof rotates so that the side where the weight 212 is attached may precede, as shown with a solid line 2A, since the weight 212 is attached to the bottom portion 21. Then the container 20 continues the rotation and further moves frontward (refer to a broken line 2B). Thereafter, when the container 20 becomes in a state where the weight 212 is positioned on the front side, the rotation is stopped (refer to a broken line 2C). Since the weight 212 and the identification mark

23 are provided on the same side of the container 20 as described above, when the weight 212 is positioned on the front side, the identification mark 23 is also positioned on the front side. That is, the identification mark 23 faces the front side. Then, the container 20 further moves to the front side while keeping a state where the identification mark 23 faces frontward (refer to a broken line 2D). Therefore, the container 20 having reached the taken-out portion is to be displayed in the state where the identification mark 23 faces frontward. Note that, in FIG. 2B, the display device 30 is exemplified in which plural rotatable roll- shaped members are provided in the placement unit 31.

[0026] FIG. 3 (FIGs. 3A to 3C) shows other configurations of the container 20.

The weight 212 may be provided on the bottom portion 21 of the container 20 and outside of the annular projecting portion 211, as shown in FIG. 3 A, for example. Alternatively, the weight 212 may be attached on the side portion 22 of the container 20 as shown in FIG. 3B. Instead of them, the weight 212 may be attached on the lid portion

24 as shown in FIG. 3C. However, depending on the attachment position of the weight 212, the container 20 may be defaced in some cases. Thus, it is the most preferable that the weight 212 should be attached to the bottom portion 21 of the container 20.

By using a larger amount of the material forming the container 20 for a portion at the identification mark 23 side, the center of gravity of the container 20 may be set to be positioned toward the identification mark 23 side. However, the illustration thereof is omitted in the first exemplary embodiment. That is, by changing a shape of the container 20 without an additional member such as the weight 212, the center of gravity of the container 20 may be positioned toward the identification mark 23 side. For example, in a manufacturing process (forming process) of the container 20, the container 20 is formed with a bending processing or the like as needed, so as to use a larger amount of the material for the portion at the identification mark 23 side. In this case, since a larger amount of the material is used for the side where the identification mark 23 is provided, the center of gravity of the container 20 is set to be positioned toward the identification mark 23 side.

[0027] Note that, the attachment of the weight 212 to the container 20 is not restricted to the above configurations. For example, the weight 212 may be attached to the container 20 with a mounting member that is mounted on the container 20.

FIG. 4 (FIGs. 4A to 4C) is a view for explaining the container 20 and a mounting member.

For example, as shown in FIG. 4A, the weight 212 may be attached to a mounting member 40 that is mounted on (fits into) the container 20 at the upper portion thereof, and that covers the upper portion of the container 20. Note that the mounting member 40 includes a first tubular portion 41 that is cylindrically formed and mounted on the container 20, and a second tubular portion 43 that is arranged inside the first tubular portion 41 and also cylindrically formed, as shown in FIGs. 4A and 4B. In addition, the mounting member 40 has a lid portion 42 that is formed into a disk shape and that covers one end of the first tubular portion 41. The weight 212 is arranged between the first tubular portion 41 and the second tubular portion 43. More specifically, the weight 212 is arranged inside the first tubular portion 41. Here, the first tubular portion 41 and the lid portion 42 may be taken as a main body formed into a tube and fitting into the upper part of the container 20. The weight 212 may be taken as a displacement member that displaces the center of gravity of the main body from an axial center thereof.

[0028] The attachment of the mounting member 40 to the container 20 is performed after the identification mark 23 and the weight 212 are aligned. Specifically, as shown in FIG. 4A, the weight 212 is positioned on the side where the identification mark 23 is applied, and then the mounting member 40 is mounted on the container 20. As a result, the center of gravity of the container 20 is positioned toward the identification mark 23 side, similarly to the above configuration. More specifically, the mounting member 40 displaces the center of gravity of the container 20 toward the side where the identification mark 23 is applied, when the mounting member 40 is mounted on the container 20 with a predetermined positional relationship with the container 20.

In the first exemplary embodiment, when the mounting member 40 is mounted on the container 20, an end part of the second tubular portion 43 of the mounting member 40 bumps into the container 20 (refer to FIG. 4A). Thus, excessive entrance of the container 20 into the mounting member 40 is prevented. The mounting member 40 according to the first exemplary embodiment has space between the container 20 and the lid portion 42 (inside the tubular portion 43), in which a gift or the like may be contained. Note that, the mounting member 40 may be attached on a lower part of the container 20, as described in FIG. 4C, instead of the upper portion of the container 20.

[0029] - Second exemplary embodiment -

FIG. 5 (FIGs. 5A to 5C) is a view showing a container 20 according to the second exemplary embodiment. Here, FIG. 5A is a side view of the container 20, FIG. 5B is a view of the bottom portion 21 of the container 20, and FIG. 5C is a view for explaining the movement of the container 20.

[0030] As shown in FIGs. 5 A and 5B, the container 20 according to the second exemplary embodiment is also provided with the annular projecting portion 211. In the second exemplary embodiment, a tape T is adhered on a part of a peak portion of the annular projecting portion 211. Note that, the position where the tape T is adhered is located on a side opposite to a side where the identification mark 23 is provided. More specifically, the identification mark 23 and the tape T are arranged so that phases thereof may be shifted by 180 degrees in the circumferential direction of the container 20.

[0031] The container 20 supplied on the back side of the display device 30 rotates since the friction coefficient of the surface of the tape T is different from the friction coefficient of the other part where the tape is not provided. Specifically, the container 20 rotates while moving to the front side, since the friction force (friction resistance) between the placement unit 31 and the tape T is larger than the friction force between the placement unit 31 and the other part where the tape T is not provided. More specifically, larger resistance force from the placement unit 31 acts on the part where the tape T is provided. Accordingly, the container 20 rotates so that the part where the tape T is not provided may precede.

As a result, the container 20 that is supplied in a state shown with a solid line 5A in FIG. 5C rotates so that the side where the tape T is provided may be turned to the back side as shown with a broken line 5B, and becomes in a state shown with a broken line 5C. That is, the container 20 becomes in a state where the side on which the tape T is provided is positioned at the back side and the identification mark 23 is positioned at the front side. Then, the container 20 moves toward a position shown with a broken line 5D while keeping a state where the identification mark 23 is positioned at the front side. Thus, also in the second exemplary embodiment, the container 20 that reaches the taken-out portion is to be displayed in the state where the identification mark 23 faces the front side. [0032] In the placement unit 31, plural roll-shaped members or ball-shaped members, which are rotatable, may be provided. When the rotation of the container 20 is performed by using difference between the friction force as in the case of the second exemplary embodiment, a flat and smooth region is preferably provided on a part of the placement unit 31 (a region where the rotation of the container 20 is performed) , as shown in FIG. 5C. That is, it is preferable that the contact portion with the container 20 should be flat and smooth without roll-shaped members or the like. Specifically, for example, a plate member having a flat and smooth surface and made of vinyl chloride or formed of bakelite is preferably used. In order to prevent occurrence of scratches by the containers 20, a plate member formed of bakelite is more preferable. In the second exemplary embodiment, a region relatively difficult to slide (region having a relatively large friction coefficient) is formed on the container 20 with the tape T. Alternatively, a region relatively easy to slide (region having a relatively small friction coefficient) may be formed on the container 20 with the tape T, and thereby rotation force is applied to the container 20.

[0033] The inventors executed an experiment with the container 20 shown in FIG. 5A, and examined the rotation performance of the container 20, and the like. Note that, in this experiment, the width B of the tape T (refer to FIG. 5B) was set at approximately 2 mm, while the length L of the tape T (length along the circumferential direction of the annular projecting portion 211, refer to FIG. 5B) was set at approximately 2.5 mm. A plate made of vinyl chloride and having a dry, flat and smooth surface was provided at the contact portion with the container 20 in the placement unit 31. The sloping angle of the placement unit 31 was set at 12 degrees. Explanation of the result was given as follows. The container 20 rotated so that the side where the tape T was provided might be turned to the back side, as described above. After that, the container 20 became in the state where the identification mark 23 faced the front side as shown with the broken line 5C in FIG. 5C.

[0034] Regions having different friction force (regions having different friction coefficients) may be formed not only by the adhesion of the tape T, but also by coating, for example. In other words, the regions having the different friction force (the regions having the different friction coefficients) may be formed by application of the material that makes the regions have the different friction force. Also, for example, by giving unevenness to the container 20 with sandblasting or the like, the regions having the different friction force (the regions having the different friction coefficients) may be formed.

FIG. 6 (FIGs. 6A and 6B) is a view showing an example in which the regions having the different friction force are formed by coating. For example, a first region 211a having a first friction coefficient and a second region 21 Ib having a second friction coefficient larger than the first friction coefficient may be formed on the peak portion (an example of a contact portion being in contact with the placement unit 31) of the annular projecting portion 211 by coating, as shown in FIGs. 6A and 6B. In this configuration, the second region 21 Ib is provided on an opposite side to a side where the identification mark 23 is provided. The first region 21 Ia is positioned at a region other than the second region 21 Ib.

[0035] The above-described first and second regions 211a and 21 Ib may be formed in the manufacturing process of the container 20, for example. Here, the container 20 is transported in a state where the bottom portion 21 is the underside thereof during a drink filling process and the like, after the manufacture. That is, the container 20 is transported in a state where the bottom portion 21 is in contact with the placement face. In this case, if the above-described first and second regions 211a and 21 Ib have been formed, the container 20 may be difficult to smoothly slide, and thus the smooth transportation may be difficult in some cases. To avoid this, after forming the first and second regions 211a and 21 Ib, it is preferable that a process for adhering a sticker or the like for covering these first and second regions 211a and 21 Ib should be added. Thereby, the container 20 may smoothly move (slide) during the drink filling process and the like. Note that, this sticker is removed when the container 20 that has been filled with drink is shipped out, or when the container 20 that has been filled with drink is placed on the display device 30. In the above description, explanation has been given for two regions, that is, the first and second regions 211a and 21 Ib, formed on the container 20 as one example. Alternatively, only the second region 21 Ib may be formed.

[0036] The first and second regions 211a and 21 Ib may be formed not only directly on the container 20, but also on the mounting member 40 that is mounted on the bottom portion 21 of the container 20, as shown in FIG. 7 (FIGs. 7A and 7B) (a view for explaining the container 20 and the mounting member 40).

The mounting member 40 includes the first tubular portion 41 that is cylindrically formed and the second tubular portion 43 that is arranged inside the first tubular portion 41 and also cylindrically formed, similarly to FIGs. 4A to 4C. Further, the mounting member 40 includes the lid portion 42 formed into a disk shape and covers the one end part of the first tubular portion 41. The mounting member 40 in this configuration includes an annular projecting portion 44 provided on the lid portion 42. The annular projecting portion 44 annularly projects toward the outside of the mounting member 40 (on an opposite side to a side where the mounting member 40 is mounted on the container 20). In this configuration, the first region 21 Ia is formed on a part of the peak portion of the annular projecting portion 44, and the second region 21 Ib is formed on the other part. More specifically, the first and second regions 211a and 21 Ib are formed on the opposite side to the side where the mounting member 40 is mounted on the container 20.

[0037] FIG. 8 (FIGs. 8A and 8B) is a view showing another configuration of the mounting member 40. Here, FIG. 8A is a partial cross sectional view of the container 20 and the mounting member 40, and FIG. 8B is a view of the mounting member 40 seen from the bottom side.

In FIGs. 7A and 7B, an example has been described in which the annular projecting portion 44 is provided on the lid portion 42 of the mounting member 40. On the other hand, as shown in FIGs. 8 A and 8B, the lid portion 42 of the mounting member 40 may be formed to be flat. To a part of the lid portion 42 formed to be flat, a sticker S having a larger friction coefficient than that of the surface of the lid portion 42 and increasing friction force between the placement unit 31 and the sticker S may be adhered, for example. The mounting member 40 in these configurations is mounted on the container 20 so that the sticker S may be positioned on the opposite side to the side where the identification mark 23 is provided, as shown in FIG. 8 A. In FIGs. 8 A and 8B, an example has been described in which the friction force is increased by the sticker S. However, the friction force may be relatively decreased by the sticker S whose surface roughness is made to be smaller than that of the lid portion 42, for example. Note that the mounting member 40 in this case is mounted on the container 20 so that the sticker S may be positioned on the side where the identification mark 23 is provided.
