DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder for transporting beverage cans for alcoholic beverages such as soft drinks and beer, and a method for producing the same.

[0002]

2. Description of the Related Art As a device for bundling a plurality of beverage cans so that they can be carried at one time, there is a conventional holder shown in FIG. This is because a plurality of, in the example shown, six cap-shaped holding parts 11 are swelled in parallel in the vertical and horizontal directions by injection molding from a main body part of a thin plate 10 made of a synthetic resin or the like as a material. The locking portion 12 of the hand strap is formed on the main body by being positioned, and the end of the hand strap 13 is inserted into the locking portion 12.

[0003] By the way, there are some beverage cans 6 which have the same capacity but have slightly different rim diameters (for example, about 2 mm) depending on the specifications. A plurality of locking pieces 14 are provided on the peripheral wall of the holding portion 11 by cutting and raising so as to cope with the problem.

The locking piece 14 is hooked on the edge of the beverage can 6 by pressing the lower portion of the edge of the beverage can from the side, thereby locking the beverage can 6 and suspending the beverage can 6 from below. The opening width changes by the elasticity obtained by forming, and it corresponds to the drink can 6 of a different can diameter.

[0005] To attach the beverage can 6 to the holding portion 11, the beverage can 6 is inserted into the holding portion 11 while pushing the locking piece 14 outward at the side of the beverage can 6, and the holding portion 11 is held. Part 11
In order to remove the beverage can 6, the beverage can 6 is pushed downward while pushing the locking piece 14 downward while the upper end of the locking piece 14 is retained at the edge of the beverage can 6.

[0006]

Since the locking piece 14 is formed by cutting and raising the peripheral wall of the holding portion 11, a bending force is applied upward without the beverage can 6 attached, and It protrudes toward. For this reason, when the beverage can 6 is mounted, the locking piece 14 is bent in the direction in which the bending force acts, so that the beverage can 6 can be easily inserted.

However, on the contrary, the beverage can 6 is held in the holding portion.
When detaching the beverage can 11, it will be bent in the direction opposite to the direction of the bending force of the locking piece 14, and the locking piece 14 has sufficient rigidity to suspend the beverage can 6 from below. As such, it does not bend easily and requires considerable force to remove the beverage can 6.

Further, the locking piece 14 is often cut at its base due to its rigidity due to an excessive bending force applied to the base in the opposite direction when the beverage can 6 is removed, and the base is often reused. Can not.

Further, a cutout 15 causes a cutout 15, which is located at the edge of the beverage can 6. If dust or dirt enters the holding section 11 from this cutout 15, the drink can 6 is cut off.
Is soiled, which is not preferable for hygiene.

[0010] An object of the present invention is to eliminate the disadvantages of the prior art and to provide a locking piece for accommodating beverage cans of different can diameters, without requiring a large force for mounting and removing the beverage can.
It can be easily and securely attached and detached, firmly held after installation and reliable in terms of strength, and the holder can be reused, preventing contamination of the lip of the beverage can, and sanitary, integrated by injection molding An object of the present invention is to provide a holder for transporting beverage cans and the like which can be molded and easily manufactured, and a method for manufacturing the same.

[0011]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention firstly provides a structure for transporting a beverage can or the like in which a plurality of cap-shaped holding portions are continuously expanded from a thin plate-shaped main body. In the holding tool, on the inner wall of the holding portion, a locking piece having elasticity and capable of being bent from the base is formed in a gentle arc shape at the base bending portion so as to protrude substantially horizontally, and the locking piece is provided. The gist is to integrally form the main body and the holding section by injection molding, and to completely cover the upper portion of the beverage can or the like with the cap-shaped holding section.

[0012] Second, the gist of the locking piece is to slightly bend the tip end in a direction opposite to the bending direction of the bent portion at the root.

Third, the invention is characterized in that ribs, which are located on both sides of the locking piece and serve as guides in the insertion direction when inserting a beverage can or the like, protrude from the inner wall of the holding portion.

Fourth, as a method of manufacturing the holder, a cap-shaped holding portion is bulged from a thin plate-shaped main body, and a bendable locking piece is projected substantially horizontally inside the peripheral wall of the holding portion. The mold for injection-molding a carrying holder such as a beverage can is obtained by dividing the mold on the core side of the part where the locking piece is injection-molded into a portion at the tip of the peripheral wall and a forming portion of the locking piece. The mold is divided into first, second, and third molds, and the first mold located outside the front end of the peripheral wall portion of the molds on the core side at the time of demolding is divided by the length of the locking piece. And then move the adjacent second mold to a position adjacent to the first mold, and then push it outward so that the locking piece is substantially parallel to the peripheral wall. While moving the third mold to the position adjacent to the second mold,
The main point is to return the mold to the original position and return the locking piece to the original position.

According to the first aspect of the present invention, by providing the locking piece substantially horizontally, the bending direction is not particularly urged, and particularly when the beverage can is attached or detached. Does not require great power. Further, since the locking piece is integrally formed by injection molding, there is no occurrence of a deficient portion in the holding portion, and it is possible to prevent the mouth edge of the beverage can from being stained, which is sanitary.

Further, since the bent portion of the locking piece is formed in the shape of an arc, the bending force of the bent portion is increased, and not only the force when pulling out the beverage can is reduced, but also the locking piece is formed at this portion. Can be prevented from being cut, and the holder can be reused. In addition, since the arc is made gentle, it is possible to prevent the bent portion from becoming clouded due to the whitening phenomenon at the time of die cutting during manufacturing.

According to the second aspect of the present invention, in addition to the above-described operation, the locking piece is configured such that the tip end is slightly bent in a direction opposite to the bending direction of the bent portion at the base, so that the beverage can When the lip is pressed by the locking piece, the tip of the locking piece naturally faces in the direction of the lip of the beverage can, so that the locking can be reliably performed.

According to the third aspect of the present invention, in addition to the above-described operation, a rib which is located on both sides of the locking piece and serves as a guide in the insertion direction when a beverage can or the like is inserted protrudes from the inner wall of the holding portion. When the beverage can is inserted along the rib into the inside of the holding portion, it can be correctly and easily mounted at a predetermined position.

According to the fourth aspect of the present invention, when the holder is integrally formed by injection molding, even if the locking piece projects substantially horizontally inside the holding portion, the die can be connected to the die. Because it is divided at the place of the stop piece, integral molding becomes possible, and furthermore,
The hinge strength of the bent portion of the locking piece can be obtained by immediately returning to the original position after removing the divided mold. Even if the mold is moved in this manner, the time required for the movement is short, and there is no possibility that the production capacity is reduced.

[0020]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a bottom view showing a first embodiment of a carrying holder for beverage cans or the like of the present invention, FIG. 2 is a plan view of the same, FIG. 3 is a cross-sectional view taken along the line CC of FIG. A main body of the tool is shown. A plurality of, in the illustrated example, six holding parts 2 are bulged upward from the main body 1 and
The locking portion 3 of the hand-held band was bulged out from the main body 1 at an appropriate interval. The main body 1, the holding part 2, and the locking part 3 are integrally formed by injection molding.

The main body 1 is made of a synthetic resin such as polypropylene as a material, and is formed of a thin plate having a substantially U-shaped cross section having a falling portion 1a formed on the periphery thereof. A plurality of rows are formed at appropriate intervals in a row.

The holding portion 2 formed by bulging upward from the main body 1 raises a trapezoidal portion 2a in a circular cap shape from the upper surface of the main body 1, and further forms a circular protruding portion 2b on the upper surface. The rib 4 as a stopper for locking to the rim of the beverage can or the like is provided downwardly from the upper lower surface of the trapezoidal portion 2a so as to be located one inside of the peripheral wall of the holding portion 2.

The ribs 4 as stoppers are formed in a thick ring shape, and furthermore, the ribs 4 are reinforced and triangular vertical ribs 4a which abut against an edge of a beverage can or the like to prevent vertical swinging. Is located outside the rib 4 and protrudes from the trapezoidal portion 2a.

Further, the locking piece 5 is slightly upwardly directed at the lower end of the trapezoidal portion 2a, that is, at the upper end position of the falling portion 1a, and between the ribs 4 and toward the inside of the holding portion 2. Protrude almost horizontally. The locking piece 5 is formed integrally with the main body 1 and the holding portion 2 by injection molding, has elasticity, and has a base portion formed to be freely bendable as shown in FIGS.

As a result, as shown in FIG. 4, the thick annular rib 4 comes into surface contact with the inside of the rim of the beverage can 6b having a small can diameter over the entire periphery thereof, and is more reliably determined by the locking piece 5. Locked in position.

Further, even when the lip of the beverage can 6b does not contact the rib 4, or when the rib 4 is not particularly thick,
Since a triangular vertical rib 4a is integrally protruded outside the rib 4, as shown in FIG. 5, the vertical rib 4a comes into contact with the edge of the beverage can 6b having a small can diameter from an oblique upper part, The upward swing is prevented, and the locking piece 5 is locked at a predetermined position by the locking piece 5 which abuts on the lower portion of the lip to prevent the downward movement.

Further, the locking piece 5 is a bent portion 5 at the base.
a was formed in a gentle arc shape. Thereby, it is possible to prevent the bent portion 5a from becoming cloudy due to the whitening phenomenon at the time of die-cutting during manufacturing, and to obtain a good-looking product.

The locking piece 5 slightly bends the tip 5c in a direction opposite to the bending direction of the bent portion 5a at the root. As a result, the lip of the beverage can 6 is

Further, ribs 16 which are positioned on both sides of the locking piece 5 and serve as guides in the insertion direction when the beverage can 6 is inserted are provided on the inner wall of the holding portion 2 so as to protrude. This rib 16 has a vertical portion 16a on the inside.
The lower part of the rib 16 is formed at the lower end of the inclined part 16b of the rib 16 when the beverage can 6 is inserted. When the beverage can 6 is pushed upward along this inclination because it comes into contact first, it is further pushed along the vertical portion 16a and is set at a predetermined position in the holding portion 2 correctly.

The method of manufacturing the locking piece 5 is based on the injection molding as described above, but as shown in FIG. Three first, second and third portions are formed at the tip of the forming portion and the falling portion 1a.
When the molds 8 and 9 are removed from the mold, the first mold 8a on the core side is first moved downward by the length of the locking piece 5, and then the second mold 8a, 8b, and 8c. The second mold 8b is moved downward from the position A to the position B in the figure, and the third mold 8c is removed downward while pushing the locking piece 5 downward. After that, the third mold 8c is returned upward, and the locking piece 5 is pushed upward to obtain the hinge strength at the root portion, and this portion is formed into an arc-shaped bent portion 5a.

The locking portion 3 of the hand strap 7 is formed in a tunnel shape having an inverted U-shaped cross section, one end of which is closed and the other end of which is opened. The end of the band 7 is inserted.

In order to attach the beverage can 6 to the holder, the upper portion of the beverage can 6 is inserted into the trapezoidal portion 2a of the holder 2 from below.
As shown by the dashed line, the locking piece 5 is bent upward at the bent portion 5a and is in a state of being pressed against the peripheral wall of the beverage can 6,
The upper part of the locking piece 5 lifts the edge of the beverage can 6 from below.

In this case, even if the diameter of the beverage can 6 is large or small, the locking piece 5 opens freely due to its elasticity and freely changes its width, and is similarly pressed against the peripheral wall of the beverage can 6, and the upper end thereof is placed at the upper end of the beverage can. The rim of the can 6 is suspended from below. 4 and 5, in the case of the beverage can 6a having a large can diameter, the bending angle of the bent portion 5a of the locking piece 5 becomes large, and the outside of the lip of the beverage can 6a is The peripheral wall portion of the trapezoidal portion 2a abuts, and this peripheral wall portion acts as a stopper, and is held in the holding portion 2 by the peripheral wall and the locking piece 5.

On the other hand, in the case of the beverage can 6b having a small can diameter,
The angle of bending of the locking piece 5 is reduced, and the beverage can 6a
The inner side of the rim abuts against the outside of the arc-shaped rib 4, which acts as a stopper and is held in the holding portion 2 by the rib 4 and the locking piece 5.

As described above, the six beverage cans 6 are locked by the holding part 2 and the hand strap 7 is pulled up vertically to lift the main body part 1. It is carried in a suspended state. In this case, since the holding portion 2 has no missing portion, there is no possibility that dirt or dust enters the holding tool and the beverage can 6 is not stained.

To remove the beverage can 6 from the holder 2, hold the lower portion of the beverage can 6 and pull it down. 6 and is pulled down together. At this time, the locking piece 5 is pulled down while bending at the bent portion 5a, and is bent downward to the vertical position shown by the chain line inside the falling portion 1a in FIG. .

The locking piece 5 is bent upward or downward by notching 5b near the bent portion 5a of the locking piece 5.
When the beverage can 6 is formed, it can be easily bent, and can be performed with a small force. Further, after the beverage can 6 is removed, the beverage can 6 easily returns to a substantially horizontal position. And since the bending part 5a gives strength to hinge force at the time of injection molding,
Reuse after returning to a substantially horizontal position is possible.
