The bottle binding tool has folded pieces (11, 12), and when the holder is attached to the bottle, the folded piece. The process of turning back is necessary. Patent Document 2 also relates to a bottle binding tool similar to Patent Document 1, and has a body binding section 2 that binds not only the bottle neck but also the body of the bottle, and the holder is used as a bottle. When mounting, a process of assembling the holder is necessary. Cited references 1 and 2 are not reference holders for binding the cans targeted by the present invention, and are only reference techniques because of differences in the shapes of the bottles and cans. It cannot be said that it has the characteristics of requiring no assembly, having a simple structure, and using a small amount of material.

  On the other hand, Patent Document 3 discloses a can holder for a single partition plate. It is recognized that the partition plate is provided with a plurality of tabs 38 around each hole 32 and the tabs fix the upper end of the can mouth. The tab 38 is formed by providing a slit 36. Since the can holder is a single partition plate, it has the characteristics of (3) no assembly required, a simple structure, and a small amount of material used. However, Patent Document 3 is a technology for packaging beverage products in a two-layer stack in a carton, and the partition plate is not provided with a finger hole, and the consumer has gathered together with the partition plate. Does not consider carrying multiple canned beverage products. For example, since the slit 36 can be a cut line, the partition plate is easily broken starting from the slit 36, so that the beverage product easily falls off the holder. Therefore, it cannot be said that (1) the consumer does not drop the beverage product from the holder while the beverage product is being carried.

  The can holder 1 is composed of a plate-like substrate 2. The plate-like substrate 2 is a single plate. The material of the plate-like substrate 2 is, for example, paper or plastic. Of these, paper is more preferable from the viewpoint of processability and disposal. The thickness of the plate-like substrate 2 is preferably 0.3 to 2.0 mm, and more preferably 0.4 to 1.5 mm.

  The perforations 3 are through holes provided in the plate-like substrate 2. The perforations 3 are preferably provided in the plate-like substrate 2 at equal intervals. On the inner peripheral edge of the perforation 3, as shown in FIG. 4, the locking pieces 4 that protrude relatively toward the center of the perforation 3 and the portions 5 sandwiched between the locking pieces are alternately arranged along the circumferential direction. Formed.

  The locking piece 4 is a portion that is substantially fitted to the lower end 12 a of the tightening portion 12 of the can lid 11. The locking piece 4 has a top edge 4 b extending in the circumferential direction of the perforation 3 and side edges 4 d extending from both ends of the top edge 4 b toward the outer periphery of the perforation 3. The shape of the top edge 4 b of the locking piece 4 is preferably a concave arc shape so as to match the outer peripheral shape of the lower end 12 a of the winding fastening portion 12. In this specification, the concave arc shape refers to an arc that swells toward the plate-like substrate 2 side. More preferably, the top edge 4b of each locking piece 4 is in contact with the same circumference R2. The diameter D2 of the circumference R2 with which the top edge 4b of the locking piece 4 contacts is preferably smaller than the outer diameter of the can lid (shown as L2 in FIG. 2). The shape of the side edge 4d of the locking piece 4 is preferably a concave arc shape.

  The angle θ of the corner 4a of the locking piece 4 is an acute angle as shown in FIG. By making the angle θ of the corner 4a of the locking piece 4 an acute angle, the can can be held strongly. The angle θ of the corner 4a of the locking piece 4 is preferably 45 ° or more and 80 ° or less, and more preferably 30 ° or more and 60 ° or less. If it is less than 45 degrees, the locking piece 4 may be deformed, and the canned beverage may fall off from the holder. If it exceeds 80 °, the force for holding the canned beverage may be insufficient, and the canned beverage may fall off from the holder. Here, the angle θ of the corner 4 a of the locking piece 4 is determined by the tangent of the top edge 4 b of the locking piece 4 passing through the corner 4 a of the locking piece 4 and the locking piece passing through the corner 4 a of the locking piece 4. 4 is an angle formed with the tangent of the side edge 4d.

  The height L1 of the locking piece 4 shown in FIG. 5 preferably has a height corresponding to 3 to 6% of the can lid outer diameter L2 of the canned beverage product 10. More preferably, it is 3 to 5%, and particularly preferably 3.5 to 4.5%. If it is less than 3%, the force for holding the canned beverage product 10 may be insufficient. If it exceeds 6%, the canned beverage product 10 may not be stably attached / detached. Here, the height L1 of the locking piece 4 is the shortest distance between the circumference R1 where the portion 5 sandwiched between the locking pieces contacts and the circumference R2 where the top edge 4b of the locking piece 4 contacts.

  The number of the locking pieces 4 is preferably 2 to 9 and more preferably 6 to 8 per hole. FIG. 4 shows a mode in which the number of the locking pieces 4 is eight as an example. If the number of the locking pieces 4 is 1 or less, the force for holding the canned beverage product 10 may be insufficient. When the number of the locking pieces 4 is 10 or more, the plate-like substrate 2 may be cracked when the canned beverage product 10 is mounted. The locking pieces 4 are preferably arranged at equal intervals in that the canned beverages 10 can be held uniformly in the circumferential direction.

  As shown in FIG. 5, the portion 5 sandwiched between the locking pieces is a portion that connects the base end portions 4c of the adjacent locking pieces 4 (4A, 4B). Here, the base end portion 4 c of the locking piece 4 is a contact point between the circumference R 1 where the portion 5 sandwiched between the locking pieces contacts and the side edge 4 d of the locking piece 4. The shape of the portion 5 sandwiched between the locking pieces is preferably a concave arc shape. More preferably, as shown in FIG. 4, it is preferable that the circumference R1 where the part 5 pinched | interposed between each locking piece contacts is the same circumference. The diameter D1 of the circumference R1 with which the portion 5 sandwiched between the locking pieces contacts is the same as the can lid outer diameter L2 or larger than the can lid outer diameter L2.

  In the can holder 1 according to the present embodiment, as shown in FIG. 4, the shape of the portion 5 sandwiched between the locking pieces on the inner peripheral edge of the perforation 3 is a shape in contact with the same circumference R <b> 1, and The top edge 4b of the stop piece 4 has an arc shape, and the center O1 of the circumference R1 where the portion 5 sandwiched between the stop pieces comes into contact with the center R1 of the circumference R2 where the top edge 4b of the stop piece 4 comes into contact. It is preferable that O2 matches. When a can (not shown) is attached to the perforations 3, the can is supported uniformly over the entire circumference of the can, and the canned beverage product 10 can be prevented from falling off the holder. A more preferable form is a shape in which the shape of the portion 5 sandwiched between the locking pieces in the inner peripheral edge of the perforation 3 is in contact with the same circumference R1, and the top edge 4b of the locking piece 4 has the same circumference R2. The center O1 of the circumference R1 in contact with the portion 5 sandwiched between the locking pieces and the circle center O2 of the circumference R2 in contact with the top edge 4b of the locking piece 4 are in agreement. Since the top edge 4b of each locking piece 4 contacts the outer periphery of a can equally, the force which supports a can becomes further equal.

  In the can holder 1 according to the present embodiment, as shown in FIG. 5, the apex of the corner 4a of the engaging piece 4A and the apex of the corner 4a of the engaging piece 4B located adjacent to the engaging piece 4A.

For example, as shown in FIG. 5, the inner peripheral edge connecting the corners 4a of the adjacent locking pieces 4A and 4B is sandwiched between the side edge 4d and the locking piece. It is the form which consists of the curve in which the part 5 continued. Since stress tends to concentrate particularly on the base end portion 4c of the locking piece 4, it is possible to prevent the breakage starting from the corners from occurring by attaching R to the base end portion 4c of the locking piece 4. .

  The plate-like substrate 2 preferably further has an annular ruled line 6 on the outer periphery of the perforations 3. The annular ruled line 6 is a recess formed by compressing the plate-like substrate 2. By forming the annular ruled line 6, the locking piece 4 can easily move up and down, and the canned beverage product 10 can be attached and detached more stably. The annular ruled line 6 is preferably concentric with the circumference R1 with which the portion 5 sandwiched between the locking pieces contacts. Further, the annular ruled line 6 is preferably formed at a position of 0 to 5 mm outward from the circumference R1 where the portion 5 sandwiched between the locking pieces contacts. More preferably, it is 1-3 mm.

  In the can holder 1 according to the present embodiment, it is preferable that the plate-like substrate 2 further includes at least two finger engagement holes 7 as shown in FIG. The finger hole 7 is a portion where the consumer puts his / her finger when carrying the beverage product. The shape of the finger engagement hole 7 is preferably such that the inner peripheral edge has no corners in order to prevent tearing starting from the corners, and is, for example, a circular shape, an elliptical shape, or a deformed shape corresponding to the finger shape.

  In the can holder 1 according to the present embodiment, as shown in FIG. 1, one of the portions 5 sandwiched between the locking pieces is disposed at a position that is the shortest distance from the finger engagement hole 7. Is preferred. When the consumer puts his finger into the finger hole 7 and lifts the beverage product, the cans act so that the cans come together to prevent the cans from falling off. The stop is easily eliminated, and the can can be removed more easily. Moreover, when a consumer puts a finger in the finger hook hole 7 and lifts the beverage product, the inner peripheral edges of the finger hook hole 7 and the perforation 3 slightly warp upward. The degree of this deformation increases particularly around the finger hole 7. For this reason, when one of the locking pieces 4 is disposed at a position that is the shortest distance from the finger engagement hole 7, the degree of deformation of the engagement piece 4 increases with deformation around the finger engagement hole 7. The locking piece 4 may come off from the lower edge 12a of the tightening portion 12 of the can lid 11, and the canned beverage product 10 may fall off.

  With reference to FIG. 2, FIG. 3, the state which bound the canned drinks 10 using the can holder 1 which concerns on this embodiment is demonstrated. When the upper end portion of the canned beverage product 10 is passed through each perforation 3, the locking piece 4 is deformed along the side wall of the can as shown in FIG. 2, and the lower edge 12 a of the tightening portion 12 of the can lid 11. To fit. Then, as shown in FIG. 3, a plurality of canned beverages 10 are bundled. When the consumer puts his finger into the finger hole 7 and lifts the beverage product, the cans repel each other and are unlikely to come off, and the canned beverage product 10 does not fall out of the holder while being carried. In FIG. 3, as an example, a configuration in which 6 pieces of 2 rows × 3 columns are bound is shown, but a desired number of canned beverages 10 can be bound by increasing or decreasing the number of perforations 3.

  Hereinafter, the present invention will be described in more detail with reference to examples, but the present invention is not construed as being limited to the examples.
