Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a can spout opening device provided on the upper surface of a can of beer or juice, for example.

[0002]

[Prior art]

 Generally, a can spout opening device forms a spout cutout line portion in a deformed elliptical shape on the upper surface of a can, and a cutout piece (also referred to as a pull tab) cut out by the cutout line portion is used to lift a finger ( It is also referred to as a pull top, and may be referred to as a pull top integrally with the pull tab).

As described above, in a general can spout opening device, first, the pull top that is in flat contact with the upper surface of the can is raised, and a finger is hung on the pull top to pull up the pull tab to pull out the cutout line. It is separated from the part and the spout is opened.

[0004]

[Problems to be solved by the device]

 However, in such a conventional can opening and opening device for a can, the pull top (which is integrated with the pull tab) is detached from the upper surface of the can after opening, and therefore, it must be treated as non-burnable dust.

Actually, this is troublesome and throws the pull-top on the road, or throws it out as ordinary burning garbage, which is a serious environmental problem.

[0006] On the other hand, a method has been developed in which the pull top does not come off, but hangs down from the spout and folds into the can. The spout opening device for a can of this type is a cutout opening piece of the spout. Since the cut-out piece is connected to the spout and hangs down in the can, the cut-out piece interferes with the outflow, resulting in a very poor spout and a difficult-to-drink spout. is there.

The present invention solves such drawbacks, and a pull-top opening device for a non-detachable can, which is excellent in practicality and has no influence on the outflow from the spout, because the pull top is integrated with the can. It is intended to be offered.

[0008]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

A spout cutout line portion 2 is formed on the upper surface 1 of the can, and a cutout piece 3 cut out by the cutout line portion 2 is provided with a pulling piece 4, and the pullup piece 4 is pulled up to cut out the cutout piece. In the can opening and opening device for a can in which 3 is cut out and the opening 5 is opened, a continuously connecting piece 6 is rotatably provided on the upper surface 1 of the can, and the continuously connecting piece 6 is continuously connected to the cutting piece 3. The present invention relates to a can opening and opening device for cans.

[0010]

[Action]

 For example, the unsealing procedure will be described with reference to the drawings illustrating the embodiment. The pulling piece 4 is raised from the state shown in FIGS. 2 and 4 (a) as shown in FIG. 4 (b), and then shown in FIG. 4 (c). In this way, the fingers are hooked on the pulling piece 4 to pull up, and the cutting piece 3 is cut out from the cut line portion 2.

In this state, the spout 5 opens, but as shown in FIG. 3 and FIG. 4D, the cutout piece 3 is further inserted through the connecting piece 6 centering on the pivoting portion 7 of the connecting piece 6. The cut piece 3 is moved from the position above the spout 5 while rotating while being connected to the top surface 1 of the can.

[0012]

【Example】

 In this embodiment, a pulling piece 4 provided with a finger hooking hole is attached to the tip end side (peripheral edge side) of the cutout piece 3 in a flat state so that the finger hooking hole can be freely raised.

Further, the base end side of the cutout piece 3 (the center side of the can) is fixedly connected to the tip of the continuous piece 6, and the base end of the continuous piece 6 is pivotally attached to the center of the upper surface 1 of the can so as to be rotatable. ing. In the drawing, the cutting piece 3 and the pulling piece 4 which are integrated with the connecting piece 6 and separated from the spout cutting line portion 2 are not separated from the can, and the cutting piece 3 and the pulling piece 4 are connected to each other. By rotating while being connected to the can upper surface 1 via the installation piece 6, it is rotated and retracted from the upper part of the spout 5, and the spout 5 is used as a spout for drinking or pouring from the spout 5. It is configured not to become. (In the drawing, the case of 180 ° retracting rotation is shown, but it may be structured such that it can be rotated slightly if it is retracted from the upper part of the spout 5.) The present invention is not limited to the above-mentioned embodiment, The spout opening / closing device for a can to which the present invention is applied (the construction of the spout cutout line portion 2, the cutout piece 3, and the pullout piece 4) can be designed as appropriate, and the shape of the continuous piece 6 and the continuous piece 6 The pivoting structure of the above and the connecting structure of the connecting piece 6 and the cut-out piece 3 can be appropriately designed.

[0014]

[Effect of device]

 Since the present invention is configured as described above, the cut-out pieces do not separate from the can and remain integrated even after opening, so there is no need to treat the cut-out pieces as non-burnable dust, and it is sufficient to treat them together with the can. It is possible to solve the current situation where pieces are thrown away, and moreover, by simply turning the cut-out piece through the connecting piece, it is possible to rotate and retreat from the upper part of the spout, so there is no effect on the outflow of the spout and the spout will Even when it is used as a drinking mouth, it does not give any support and can be realized with a simple structure, so it is a can opening and opening device with excellent practicality such as excellent mass productivity.
