EMBODIMENT OF THE INVENTION Hereinafter, with reference to drawings as needed, the example of embodiment of the coaster which concerns on this invention, and a beverage can with a coaster is demonstrated.

First, an example of an embodiment of a coaster according to the present invention will be described.

(First embodiment)
A first embodiment of the present invention will be described with reference to FIGS. 1 and 2 of the drawings. FIG. 1 is a perspective plan view of a coaster 101 according to the first embodiment. FIG. 2 is a bottom perspective view of the coaster 101 according to the first embodiment.

A coaster 101 according to the first embodiment is a coaster for placing a beverage can 20 thereon, and is made of a water-absorbing material.

The beverage can 20 to be placed is, for example, a so-called two-piece can manufactured by plastically deforming aluminum to seamlessly form the body portion 22 and the bottom portion 23, and by seaming the lid portion 21. . Generally, the two-piece can has a circular bottom portion 23 that is one size smaller than the body portion 22 when viewed vertically. The beverage can 20 placed on the coaster 101 according to the first embodiment is also a two-piece can in which the bottom portion 23 has a circular shape slightly smaller than the body portion 22 when viewed from the vertical direction. The body portion 22 of the beverage can 20 has a substantially cylindrical shape, and the diameter of the body portion 22 is the maximum diameter of the beverage can 20 .

A material having water absorption is, for example, so-called coaster paper, which has high water absorption and water retention due to its low density. Coaster paper is also suitable for printing and embossing because of its high water retention.

The coaster 101 has a circular shape when viewed from the vertical direction. The outer diameter 1 of the coaster 101 is equal to or smaller than the maximum diameter of the body portion 22 of the beverage can 20 and equal to or larger than the maximum diameter of the bottom portion 23 of the beverage can 20 .

Since the outer diameter 1 of the coaster 101 is the same as or smaller than the maximum diameter of the body portion 22 of the beverage can 20 placed thereon, it can be attached to the lid portion 21 or bottom portion 23 of the beverage can 20 without bending. As will be described later, it can be stored in a container such as a blister pack that covers the lid portion 21 or the bottom portion 23 of the beverage can 20 without being bent, and can be distributed.

The coaster 101 is made of a water-absorbing material, and the outer diameter 1 is the same as or larger than the maximum diameter of the bottom portion 23 of the beverage can 20 . It travels along the portion 22 to reach the bottom portion 23 and is absorbed by the coaster 101 in contact with the bottom portion 23 in combination with capillary action due to a minute gap formed between the bottom portion 23 and the coaster 101 . It is possible to prevent water droplets from wetting the place where the beverage can 20 is placed.

(Second embodiment)
A second embodiment of the present invention will be described with reference to FIGS. 3 and 4 of the drawings. FIG. 3 is a perspective plan view of the coaster 102 according to the second embodiment. FIG. 4 is a bottom perspective view of the coaster 102 according to the second embodiment.

A coaster 102 according to the second embodiment is the same as the coaster 101 according to the first embodiment except that the double-sided tape 10 is attached to the upper surface 2 of the coaster. Here, the "upper surface" means the surface on which the beverage can 20 is placed.

The double-sided tape 10 may be, for example, a commercially available double-sided tape in which adhesive layers are provided on both sides of a base material and a separator is provided on the surface of one of the adhesive layers. The double-sided tape 10 is used to secure the bottom 23 of the beverage can 20 to the top 2 of the coaster 102 . The portion to which the double-sided tape 10 is attached may be the entire upper surface 2 of the coaster 102 or only the portion in contact with the beverage can 20 . For example, the commercially available double-sided tape 10 is cut to approximately the maximum diameter of the coaster 102 , and is attached from one end to the other end of the coaster 102 . Also, the size, shape, and position of the double-sided tape 10 attached to the coaster 102 are not particularly limited as long as it can be used to fix the bottom 23 of the beverage can 20 to the upper surface 2 of the coaster 102.

The double-sided tape 10 allows the coaster 102 to be easily attached to the bottom portion 23 of the beverage can 20, and can also be removed when the coaster 102 is discarded. In addition, since the coaster 102 remains attached to the bottom portion 23 of the beverage can 20 even when the placed beverage can 20 is lifted, the coaster 102 is removed every time the beverage can 20 is placed on the coaster 102 after being lifted. It is convenient without trouble to confirm place. Furthermore, coupled with the capillary action caused by the minute gap corresponding to the thickness of the double-sided tape 10 formed between the coaster 102 and the beverage can 20, more water droplets can be absorbed.

(Third Embodiment)
A third embodiment of the present invention will be described with reference to FIGS. 5 and 6 of the drawings. FIG. 5 is a perspective plan view of the coaster 103 according to the third embodiment. FIG. 6 is a bottom perspective view of the coaster 103 according to the third embodiment.

A coaster 103 according to the third embodiment has a bottom surface portion 4 and a peripheral wall portion 5. The peripheral wall portion 5 is formed on the outer peripheral edge of the bottom surface portion 4 so as to be inclined outward toward the top. , and other than that, it is the same as the coaster 101 according to the first embodiment. Here, "above" means above the top surface 2 of the coaster 103 when the top surface 2 is up.

By having this peripheral wall portion 5, the adhesion between the coaster 103 and the beverage can 20 is improved, and water droplets collected on the coaster 103 on which the beverage can 20 is placed are less likely to spill outside the coaster 103. In addition, since the area in close contact with the bottom portion 23 of the beverage can 20 is increased, the water droplet absorption efficiency is improved. When the coaster paper is used, the peripheral wall portion 5 improves the adhesion to the beverage can 20, so that the water retention effect of the coaster paper is further exhibited. As a method for forming the peripheral wall portion 5, for example, a flat paper is sandwiched between a male mold and a female mold by press molding, or a plurality of cuts are formed in the outer peripheral edge of a circular flat paper on the side in contact with the outer peripheral edge. A method of winding the inserted belt-shaped paper and adhering it to a circular flat paper can be mentioned. When the latter method is adopted, a circular flat paper forms the bottom portion 4 and a strip of paper forms the peripheral wall portion 5 .

When the coaster 103 has the bottom portion 4 and the peripheral wall portion 5 in this manner, the diameter of the bottom portion 4 is preferably equal to or larger than the maximum diameter of the bottom portion 23 of the beverage can 20 . This is because if the diameter is less than the maximum diameter, the bottom portion 23 of the beverage can 20 may ride on the peripheral wall portion 5 and the beverage can 20 may topple over.

(Fourth embodiment)
A fourth embodiment of the present invention will be described with reference to FIGS. 7 and 8 of the drawings. FIG. 7 is a perspective plan view of the coaster 104 according to the fourth embodiment. FIG. 8 is a bottom perspective view of the coaster 104 according to the fourth embodiment.

A coaster 104 according to the fourth embodiment is the same as the coaster 103 according to the third embodiment except that the double-sided tape 10 is attached to the upper surface 2 of the coaster.

The double-sided tape 10 is a commercially available double-sided tape having pressure-sensitive adhesive layers on both sides of a base material and a separator on the surface of one pressure-sensitive adhesive layer, as in the coaster 102 according to the second embodiment. The double-sided tape 10 is used to secure the bottom 23 of the beverage can 20 to the top 2 of the coaster 104 . The portion to which the double-sided tape 10 is attached may be the entire upper surface 2 of the coaster 104 or only the portion in contact with the beverage can 20 . As shown in FIG. 7 , in a coaster having a peripheral wall portion 5 , when the bottom surface portion 4 and the peripheral wall portion 5 are in contact with the beverage can 20 , the double-sided tape 10 extends from the bottom surface portion 4 to the peripheral wall portion 5 and extends over the coaster 104 . It is glued from one end to the other. The size, shape, and position of the double-sided tape 10 attached to the coaster 104 are not particularly limited as long as it can be used to fix the bottom portion 23 of the beverage can 20 to the top surface 2 of the coaster 104 .

The double-sided tape 10 allows the coaster 104 to be easily attached to the bottom 23 of the beverage can 20, and can also be removed when the coaster 104 is discarded. In addition, since the coaster 104 remains attached to the bottom portion 23 of the beverage can 20 even when the placed beverage can 20 is lifted, the coaster 104 is removed every time the beverage can 20 is placed on the coaster 104 after being lifted. It is convenient without trouble to confirm place. Furthermore, coupled with the capillary phenomenon caused by a minute gap corresponding to the thickness of the double-sided tape 10 formed between the coaster 104 and the beverage can 20, more water droplets can be absorbed.

Next, an example of an embodiment of a beverage can with a coaster according to the present invention will be described.

The coaster-equipped beverage according to the present invention includes, for example, the coaster according to any one of the first to fourth embodiments described above, the beverage can 20, and the container 30 in which the coaster is stored. The stored coaster is attached to the lid portion 21 of the beverage can 20. - 特許庁

Here, as an example, a beverage can 201 with a coaster attached with a coaster 104 according to the fourth embodiment will be described with reference to FIGS. 7 to 9 of the drawings. FIG. 9 is a front perspective view of an example of a coaster-equipped beverage can 201 to which a coaster 104 according to the fourth embodiment is attached.

The coaster-equipped beverage can 201 includes the coaster according to the fourth embodiment, the beverage can 20, and the container 30 in which the coaster is stored. 21 is attached.

The beverage can 20 is, for example, a two-piece can as described above, and has a circular bottom portion 23 that is one size smaller than the body portion 22 when viewed from the vertical direction. The body portion 22 of the beverage can 20 has a substantially cylindrical shape, and the diameter of the body portion 22 is the maximum diameter of the beverage can 20 . A spout (not shown) is provided in the lid portion 21 of the beverage can 20, and a rib 24 continuous along the circumferential direction is formed on the upper edge.

The container 30 in which the coaster 104 is stored is, for example, a so-called blister pack formed by thermoforming a resin film. The container 30 has a top surface portion 31 and a peripheral surface portion 32 and has a circular cap shape substantially corresponding to the beverage can 20 . An engaging portion 33 is formed at the lower end portion of the peripheral surface portion 32 so as to be integrated with the peripheral surface portion 32 . The engaging portion 33 is a portion for engaging with the beverage can 20 , protrudes toward the inside of the container 30 , and is continuously formed along the circumferential direction of the peripheral surface portion 32 .

The coaster 104 is placed on the surface of the lid portion 21 of the beverage can 20 on which the spout is formed, with the upper surface 2 of the coaster 104 facing upward, and the inner surface of the top surface portion 31 of the container 30 facing downward. The container 30 is attached to the lid portion 21 of the beverage can 20 in such a manner that the container 30 is placed over the coaster in the facing state. Further, when the container 30 is attached to the beverage can 20, the container 30 is pushed into the beverage can 20, and the engaging portion 33 of the container 30 overcomes the rib 24 on the upper edge of the beverage can 20 by elastic deformation. It engages the underside of rib 24 . In FIG. 9, the bottom portion 4 of the coaster 104 is transparent and the lid portion 21 of the beverage can 20 is visible in order to clearly show the arrangement state of the coaster 104 on the beverage can 20. However, the bottom portion of the coaster 104 is actually shown. Lid 21 is not visible unless 4 is transparent.

Note that the coaster 104 may be placed on the surface of the lid portion 21 of the beverage can 20 on which the spout is formed, with the bottom surface 3 of the coaster 104 facing upward instead of the top surface 2 . Here, the “lower surface” means the surface opposite to the surface on which the beverage can 20 is placed.

Also, a coaster 104 may be attached to the bottom portion 23 of the beverage can 20 . For example, the coaster 104 is placed under the bottom portion 23 of the beverage can 20, and the container 30 is placed over the coaster 104 with the inner surface of the top surface portion 31 of the container 30 facing upward. 23 is attached. In this case, there is a method of attaching the container 30 to the bottom portion 23 with a double-sided tape or the like having a peelable adhesive layer without providing the engaging portion 33 on the container 30 . When the coaster 104 is attached to the bottom portion 23 of the beverage can 20, the coaster 104 may be arranged with the upper surface 2 of the coaster 104 facing upward, or with the lower surface 3 of the coaster 104 facing upward. It's okay.

Since the outer diameter 1 of the coaster 104 is equal to or smaller than the maximum diameter of the body 22 of the beverage can 20 placed thereon, as shown in FIG. It is possible to store and circulate without bending in a container 30 such as a blister pack.

Preferably, the container 30 is wholly or partially transparent so that the coaster 104 can be seen.

As described above, the coaster is attached to the beverage can 20 in a state of being housed in the container 30, and the coaster can be distributed while attached to the beverage can 20 without deformation or breakage of the coaster. Therefore, for example, the present invention can be applied when a coaster is attached as a prize to a beverage can 20 sold by a vending machine.

When removing the coaster 104 from the container 30 in the example of the coaster-equipped beverage can 201 described above, the container 30 is lifted upward to disengage the engaging portion 33 from the ribs 24, and the container 30 is removed from the beverage can 20. , the coaster 104 can be removed from the container 30 .

Note that the coaster is placed regardless of whether the coaster according to any one of the first to third embodiments is attached to the beverage can 20, or whether the coaster is attached to the lid portion 21 or the bottom portion 23 of the beverage can 20. As for the orientation, the upper surface 2 of the coaster may be directed upward, or the lower surface 3 of the coaster may be directed upward.

Next, an example of how to use the coaster according to the present invention will be described.

When the coaster 101 according to the first embodiment is used, the beverage can 20 is placed on the coaster 101 so that the bottom portion 23 of the beverage can 20 does not protrude from the coaster 101 .

When the coaster 102 according to the second embodiment is used, the separator is peeled off from one adhesive layer of the double-sided tape 10 attached to the upper surface 2 of the coaster 102, and the upper surface 2 of the coaster 102 is turned upward. The coaster 102 is attached to the bottom part 23 of the beverage can 20 so that the bottom part 23 of the beverage can 20 does not protrude from the coaster 102 by .

When the coaster 103 according to the third embodiment is used, the bottom portion 4 of the coaster 103 and the bottom portion 23 of the beverage can 20 are aligned with the top surface 2 of the coaster 103 facing upward, and the beverage can 20 is placed. It is placed on the coaster 103 .

How to use the coaster 104 according to the fourth embodiment will be described with reference to FIG. 10 of the drawings. FIG. 10 is a perspective view showing an example of how the coaster 104 according to the fourth embodiment is used.

First, the separator is peeled off from one adhesive layer of the double-sided tape 10 attached to the upper surface 2 of the coaster 104 . The coaster 104 is attached to the bottom part 23 of the beverage can 20 so that the bottom part 4 of the coaster 104 and the bottom part 23 of the beverage can 20 are aligned with the upper surface 2 of the coaster 104 facing upward. By doing so, the beverage can 20 and the coaster 104 are integrated as shown in FIG.

When the beverage can 20 is cold, after a while dew condensation occurs on the body 22 of the beverage can 20, and water droplets adhering to the surface of the beverage can 20 begin to move downward. The coaster 104 is made of a water-absorbing material and has an outer diameter 1 equal to or larger than the maximum diameter of the bottom portion 23 of the beverage can 20. Therefore, water droplets adhering to the surface of the beverage can 20 travel along the body portion 22 of the beverage can 20 and reach the bottom portion. 23 and is absorbed by the coaster 104 in contact with the bottom 23 in combination with capillary action due to the minute gaps formed between the bottom 23 and the coaster 104 , so that the water droplets on the surface of the beverage can 20 move the beverage can 20 . It is possible to prevent the placed place from getting wet.

In addition, when the coaster 102 according to the second embodiment or the coaster 104 according to the fourth embodiment is used, a small amount corresponding to the thickness of the double-sided tape 10 formed between the coasters 102 and 104 and the beverage can 20 is applied. Combined with the capillary phenomenon caused by the gap, it can also absorb more water droplets.
