It is a figure explaining the center sectional view of the drinking cap of a beverage container. It is sectional drawing explaining the state which accumulated two drinking caps. (A) is a top view of a drinking cap, (b) is a bottom view of the drinking cap. It is a figure explaining the elastomer-type AR-800 series physical property table | surface of Aronkasei Co., Ltd. as a typical example of the flexible raw material which forms a drinking cap.

  FIG. 1 is a diagram for explaining a central cross-sectional view (a cross-sectional view taken along a broken line A-A ′ in FIG. 3A) of a drinking cap 1000 for a beverage container. The drinking cap 1000 of the beverage container may have the same central cross-sectional view observed from the front, back, right side, and left side.

  As shown in FIG. 1, the drinking cap 1000 includes a top plate portion 1010 having a disk-like shape whose center is a weak crown and a first inclined portion that is inclined outward and downward from the edge portion of the top plate portion 1010. And a tapered portion 1020.

  The first tapered portion 1020 may be formed so that the distance from the center is in the range of 25 mm to 29 mm, for example. As a result, the inner wall of the first tapered portion 1020 can be brought into contact with the mouth of a plastic bottle having a mouth diameter in the range of 25 mm to 29 mm.

  The drinking cap 1000 is preferably formed of a flexible material, and the inner wall of the first tapered portion 1020 that is in contact with the mouth of the plastic bottle can be in close contact with the circumferential mouth of the plastic bottle. Prevent insects, dust, garbage, etc. from entering the PET bottle.

  In addition, the drinking cap 1000 includes a hook-shaped connecting portion 1030 that continuously protrudes outward from the first tapered portion 1020. The connecting portion 1030 may be parallel to the top plate portion 1010 and is preferably formed horizontally. In addition, the drinking cap 1000 includes a second tapered portion 1040 that is formed from the outer edge of the connecting portion 1030 toward the outside and downward.

  The second tapered portion 1040 may be formed so that the distance from the center is, for example, 48 mm to 54 mm. Thereby, the inner wall of the 2nd taper part 1040 can contact | abut and respond | correspond to the opening | mouth of canned coffee, a green tea can, etc. (1st drink container) in the range whose mouth outer diameter is 48 mm thru | or 54 mm.

  The drinking cap 1000 is preferably formed of a flexible material, and the inner wall of the second tapered portion 1040 that is in contact with the mouth of canned coffee, green tea can, etc. It can adhere to the diameter and prevent insects, dust, garbage, etc. from entering the plastic bottle.

  Further, the drinking cap 1000 may include a third tapered portion 1050 that is formed further outward and downward from the second tapered portion 1040. As shown in FIG. 1, the third tapered portion 1050 can be formed such that the distance from the center is within a range of 56 mm to 62 mm, for example. Thereby, the inner wall of the 3rd taper part 1050 can contact | abut and respond | correspond to the opening | mouth of beer cans etc. (2nd drink container) in the range whose mouth outer diameter is 56 mm thru | or 62 mm.

  The drinking cap 1000 is preferably formed of a flexible material, and the inner wall of the third tapered portion 1050 that is in contact with the mouth of a beer can or the like is in close contact with a circumferential mouth outer diameter of can coffee or the like This prevents insects, dust, garbage, etc. from entering the plastic bottle. A hook-shaped connecting portion may be further provided between the second tapered portion 1040 and the third tapered portion 1050. This connecting portion may be formed horizontally in parallel with the top plate portion 1010.

  Further, as can be understood from FIG. 1, the outer wall of the first taper portion 1020 is provided with at least one overlapping convex portion 1060. Even when two drinking caps 1000 are stacked by the overlapping convex portion 1060, a space is formed between the two drinking caps 1000 that are stacked, and the two drinking caps 1000 are in close contact like a suction cup. Therefore, it can prevent adsorbing each other. One or more arbitrary numbers of the convex portions for superimposing 1060 can be provided.

  The bottom surface of the third taper portion 1050 is provided with at least one air conduction convex portion 1070. Thereby, even when the drinking cap 1000 is placed on a flat surface such as a dining table, it can be easily taken up.

  If the air conduction convex portion 1070 is not provided, if the drinking cap 1000 is formed of a flexible material, it looks like a suction cup when placed on a flat surface such as a table. It is feared that it adsorbs to the flat surface. However, since air is easily guided to the internal space formed by the drinking cap 1000 and the table by the air conduction convex portion 1070, it can be prevented from being adsorbed. Further, a groove may be formed instead of the air conduction convex portion 1070 to form an air conduction concave portion. One or more arbitrary numbers of the air conduction convex portions 1070 can be provided.

  Moreover, as shown in FIG. 1, the top plate part 1010 and the first taper part 1020 are stored in a state where the pull top steon tab of the can beverage is raised (opened state). A tab housing 1080 is formed.

  Even if the top of the can beverage is covered with the second tapered portion 1040 or the third tapered portion 1050 of the drinking cap 1000 by the pull top steon tab housing 1080, the pull top steon tab of the can beverage has no obstacle. The inner wall of the 2nd taper part 1040 or the 3rd taper part 1050 can closely_contact | adhere to the circumferential mouth external shape of a can drink appropriately.

  FIG. 2 is a cross-sectional view illustrating a state where two drinking caps 1000 are stacked. As can be understood from FIG. 2, the superposition convex portions 1060 (1) and (2) indicate that the drinking caps 1000 (1) and 1000 (2) are closely attached and adsorbed when they are stacked. Can be prevented.

Further, as shown in FIG. 2, the drinking cap 1000 made of a flexible material has a thickness (L ₁ ) of the connecting portions 1030 (1) and (2) of the first tapered portion 1020 (1 ) And (2) are preferably thicker than the thickness (L ₂ ).

  Accordingly, when the inner wall of the first tapered portion 1020 is brought into contact with the mouth of the plastic bottle, the inner wall of the first tapered portion 1020 can flexibly fit and closely adhere to the mouth of the plastic bottle. A gentle suction force can be demonstrated like a weak suction cup. Therefore, in the state where the drinking cap 1000 is attached to the plastic bottle, even when some vibration or shaking occurs, the concern that the drinking cap 1000 is easily detached can be reduced.

The thicknesses of the second tapered portion 1040 and the third tapered portion 1050 are the same as the thickness (L ₂ ) of the first tapered portion 1020, respectively. The three tapered portions 1050 can be easily and flexibly fitted to the outer edge portions of the mouth of the can beverage, and the drinking cap 1000 can be attached with a gentle adsorbing force by the close contact.

  As can be understood from the above description, the drinking cap 1000 is preferably made of a flexible material so that a gentle suction force such as a suction cup can be easily exerted. In addition, since the thickness of each of the tapered portions 1020, 1040, and 1050 is thinner than the thickness of the connecting portion 1030 and the top plate portion 1010, the overall shape of the drinking cap 1000 is maintained. However, at the contact portion with the beverage container, the beverage container is more flexibly and closely attached to the circumferential mouth shape of the beverage container and is attached thereto.

  More specifically, the inner wall of each of the tapered portions 1020, 1040, and 1050 that are in contact with the outer shape of the mouth of the beverage container during the mounting operation of the drinking cap 1000 receives a light pressing force from above and comes into contact with the beverage container. The part is closely attached so that it can be temporarily pushed outside the weak crown. After that, when the mounting operation is completed and the pressing force from above disappears, the drinking cap 1000 tries to return to the upper side of the weak crown due to the taper, while the drinking cap 1000 moves downward due to the gentle suction force like a suction cup. In order to receive the adsorption force, the beverage container is firmly attached at a position where both forces are balanced.

  Further, in the case of carbonated beverages or the like in which gas is generated from the beverage itself, the reduced pressure state of the pull top steon tub housing 1080 is eliminated in a relatively short time by the internally generated gas, and the suction force similar to a suction cup is relatively short. It will be resolved in time. Even in this case, the edge portion of the mouth outline and the inner walls of the tapered portions 1020, 1040, and 1050 are in close contact with each other, so that the drinking cap 1000 does not come off, and insects, dust, and the like are shut out. The cap function is maintained.

  FIG. 3A is a plan view of the drinking cap 1000, and FIG. 3B is a bottom view of the drinking cap 1000. 3 (a) and 3 (b), the superimposing convex portion 1060 and the air conducting convex portion 1070 are each provided with one and four typical examples, but are not limited thereto. One or more arbitrary numbers can be provided at any location. The air conduction convex portion 1070 may be a protrusion having a height of 1 mm, for example. The broken line A-A ′ shown in FIG. 3A indicates the cross-sectional position in FIG. 1.

  Moreover, FIG. 4 is a figure explaining the elastomer type | system | group AR-800 series physical property table | surface of Aronkasei Co., Ltd. as a typical example of the flexible raw material which forms the drinking cap 1000. FIG.

  In FIG. 4, it is preferable to use a material having a softening temperature of 80 ° C. to 148 ° C. because it can be applied to a hot beverage container. In FIG. 4, the hardness (instantaneous value) of about 50 to 90 is preferable from the viewpoint of achieving appropriate flexibility. Even if PP (polypropylene) is blended as appropriate, the hardness is adjusted. Good.

  In addition to the flexible material shown in FIG. 4, a soft resin material such as urethane, silicon, or other elastomer may be used. Even in this case, it is preferable that the hardness (instantaneous value) is set to about 50 to 90 by blending materials.

  Moreover, although the drinking cap 1000 shown by this embodiment is disclosing the structure provided with three taper parts as a typical example, it is not limited to this. For example, it is good also as a structure provided with two taper parts, the 1st taper part 1020 and the 3rd taper part 1050. FIG. Moreover, it is good also as a structure provided with two taper parts, the 2nd taper part 1040 and the 3rd taper part 1050. FIG. Moreover, it is not limited to a plastic bottle and a can drink, If it is a drink container corresponding to the aperture of each taper part, it can also be equipped as caps, such as a ceramic cup.

  The above-described drinking cap 1000 is not limited to the description in the embodiment, and the configuration, material, mounting method, and the like are appropriately changed within the scope of the technical idea described in the present embodiment and the obvious range. can do. Moreover, it is preferable that the drinking cap 1000 is integrally formed.
