Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an opening device for an easy-open can container that has an easily peelable opening piece with a ring on the lid surface. The present invention relates to an opening tool that has a notched recess and a ring holding means for removably attaching a cut-off opening piece to the upper part of the tip.

[Technology background]

2. Description of the Related Art So-called easy-open cans, which have an easily removable opening piece formed on a portion of the lid surface that closes the can, are widely used for containers for soft drinks and the like.

In this type of easy-open can container, the opening is formed by pulling the tab or ring connected to the tip of the opening piece with your finger and separating the opening piece from the lid surface, but when peeling off, a certain amount of force is applied. This is not necessarily easy for young children and others, and in particular, the final stage of separation is difficult, resulting in accidental injury to the hands.

For this reason, an opening tool has been developed in which the tip of the opening tool is hooked onto the tab of the opening piece and the stress is used to separate it from the lid surface, so that even young children can easily open the opening. Since the opening piece is in contact with the upper surface of the opening piece itself from beginning to end, it becomes difficult to separate the latter half, and there is a drawback that a smooth opening operation cannot be performed.

In addition, when the opening piece is separated from the can lid, the repulsive force causes it to fly off with considerable force, potentially injuring the eyes or face.Furthermore, it is troublesome to collect the scattered opening piece, so it is left unattended, causing pollution. It is also a contributing factor.

[Purpose of invention]

In view of the above problems, the purpose of the present invention is to make it possible to reliably and safely separate the opening piece with a small force so that even young children can easily open easy-open cans of soft drinks, etc., and to simultaneously remove the opening piece. To provide an easy-open can opening tool which automatically locks and holds the can to prevent the opening piece from scattering.

[Summary of the idea]

In the present invention, the tip of the main body frame of an opening device having a gripping portion at the rear is an engaging portion that is inserted into a ring-shaped tab of a can severing piece, and the lower surface of the frame has a bulging portion that comes into contact with the lid surface of the can. and a cutout recess having a downwardly inclined surface that engages with the periphery of the can at the rear of the bulging portion, and a ring portion of the cut-off opening piece is formed above the end engagement portion of the frame. It is characterized by forming a ring holding part in the shape of a tombstone which can be hooked and held.

[Example of idea]

An embodiment of the present invention will be described below based on the drawings.

As shown in FIG. 5, the easy-open can 1 integrally has an opening piece 4 that can be separated along a tear line in a part of the lid 3 that closes the upper peripheral edge 2 slightly below. A tab or ring portion 5 for separating the opening piece is integrally formed at one end of the holder, or is connected with an eyelet or the like. Although not shown in the drawings, some easy-open cans have the ring portion 5 folded back so as to overlap the opening piece 4.

FIG. 1 shows a side view of the opening tool of the present invention for opening these easy-open can containers. Engagement part 1 inserted into opening ring part 5 of open can 1
It is formed in 3. The upper surface of the engaging part 13 is the opening piece 4
It may be formed to have a rough surface with a corrugated cross section so that it can be easily engaged with the ring 5.

On the lower surface of the frame 11, a bulge 14 is formed behind the tip engaging portion 13 and projects downward, and a cutout recess 16 having a rearwardly downwardly inclined surface 15 is formed behind the bulge 14. It has been formed.

The bulging portion 14 is provided at a position where it comes into contact with the upper surface of the can lid 3 when the can lid 3 is opened, and the downwardly inclined surface 15 is provided at a position where it engages with the peripheral edge 2 of the can 1 when the can 1 is opened. The inclined surface 15 formed on the lower surface of the frame 11 comes into contact with the edge 2 of the can 1 in the latter half of the can opening operation and becomes a pivot point for the opening tool, and the dimension between the edge 2 and the opening ring 5 is It is formed to extend a predetermined length in the front-rear direction so that it can be commonly applied to many types of easy-open cans with different types. In addition, descending slope 1
5 may be formed in a sawtooth shape. In addition, the notch recess 1
The maximum cutting depth 6 is smaller than the upright dimension of the edge 2 of the can 1. A detached opening piece 4 is provided above the tip engaging part 13 inserted into the opening ring part 5 of the can lid 3.
A ring holding part 17 in the shape of a tombstone is integrally provided to hook and engage the ring part 5.

This ring holding part 17 is the ring part 5 of the opening piece 4.
It is integrally provided so as to form a gap 17c for attaching and detaching the ring between the notch opening 17a for receiving and holding the ring, and the upper surface of the frame 11 extending in a hook shape from the top of the tip of the opening 17a. The ring portion 5 of the unsealing piece 4 inserted from the engaging portion 13 is held in the opening 17a by the locking piece 17b.

The locking piece 17b is preferably made of a material and shaped so that its tip can be bent inward and outward of the opening 17a with an appropriate pressing force. For example, when the opening tool is made of plastic, the tip of the locking piece 17b can be made gradually thinner so that the locking piece 17b can be bent with appropriate elasticity. When the locking piece 17b is made flexible in this way, the gap 17c between the tip of the locking piece 17b and the upper surface of the frame tip engagement portion 13 can be made narrower than the cross section of the ring portion 5, so that the ring can be locked. and retention becomes more reliable.

The opening tool of the present invention may be made of plastic, metal, or other relatively strong known materials. When integrally molded with plastic or the like as shown in the figure, the edge of the frame 11 from the end engaging part 13 to the grip part 12, the bulge part 14, and the edge of the descending slope 15 of the notch recess 16 are made to project outward. wide plate 18
to form. With this configuration, the mechanical strength of the frame as a whole is increased, and the engagement surface with the can is widened, so that a sense of stability in use can be obtained.

However, the main body frame of the present invention is not limited to the structure shown in the figure.
A pair of plates in which a ring engagement part 13, a bulge 14, and a notch recess 16 are formed may be integrally joined vertically at a constant interval. A structure in which they are connected in parallel via a spacer or the like may also be used.

Since the present invention is used as a can opening device particularly for young children, it is preferable that the ring engaging portion 17 be used as a mouth portion, the rear portion thereof be used as a head portion, and the entire device be formed in the shape of an animal. Incidentally, in the illustrated embodiment, the opening tool is modeled in the shape of an eagle.

When opening an easy-open can container using the opening tool of the present invention, first, hold the rear grip part 12 of the opening tool 10 and insert the tip engaging part 13 into the ring part 5 of the can opening piece. The part 5 is inserted into the opening 17a of the ring holding part 17 through between the upper surface of the engaging part 13 and the tip of the locking piece 17b. Next, when the bulging part 14 on the lower front surface of the frame is brought into contact with the closing lid 3 of the can, and the grip part 12 is rotated downward using the bulging part 14 as a fulcrum, the tip of the opening piece 4 connected to the ring 5 will be released. It is pulled upward along its edge and separated from the lid 3, and initial opening is performed. When the opening tool 10 is further rotated in the same direction, the inclined surface 16 formed at the lower part of the frame 11 comes into contact with the edge 2 of the can 1 while the opening piece 4 is being separated. Next, when the frame 11 is further rotated in the same direction using the point of contact between the inclined surface 16 and the can rim 2 as a fulcrum, the bulging portion 14 of the frame 11 rises upward from the top surface of the lid 3, and as a result, the can opening becomes impossible. The piece 4 is pulled upward together with the bulge 14, and the opening further progresses (see FIG. 3). At this point, the unsealing piece 4 is almost open, but if an unopened part remains at the end, the tip of the unsealing ring 5 is supported by the opening 17a formed in the upper part of the frame 11, and the entire frame 11 is opened. When the opening piece 4 is gently shaken from side to side, the remaining part of the opening piece 4 is completely separated from the lid 3. Opening 1 in the upper part of the frame body to which the ring part 5 is attached
Since most of the periphery of 7 is closed, the separated opening piece 4 is held in the opening 17 via the ring part 5 without flying around (phantom line in FIG. 3), and the opening piece 4 4 forward, the ring part 5 expands the gap 17c between the top surface of the frame 11 and the tip of the locking piece 17b, and the ring holding part 1
Easily removed from 7.

[Effect of idea]

In the opening tool of the present invention, in the first half of the opening operation, the top of the front of the lower cutout contacts the lid and rotates using this as a fulcrum, so that the initial separation of the opening piece is done safely and reliably, and in the second half of the opening operation Since the rotational fulcrum is moved to the point of engagement between the inclined surface of the lower cutout and the rim of the can, that is, to the rear of the top, there is no risk that the top interferes with the separation of the opening piece and makes it impossible to open the seal, and a series of The opening piece can be reliably separated by operation. Further, since the inclined surface extends in the front-rear direction, there is an advantage that it can be used in common with many types of cans having different sizes.

Furthermore, in the final stage of separation, the ring of the opening piece is securely held in the engagement part, so there is no risk of the opening piece flying off due to the force of the recoil spring, making it safe, and preventing pollution by eliminating the need to throw away the separated opening piece. It also has excellent effects.
