Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a handy punch capable of forming a large number of small holes at once in a synthetic resin film such as a polyolefin film or a polyvinyl chloride film. In particular, it relates to a small punch that can safely drill a large number of small holes at once. Further, the present invention relates to a punch which is made water-permeable by making a large number of holes having a diameter of about 1 mm to 3 mm at a time in a water-impermeable synthetic resin film, and which is convenient for providing drainage performance.

[0002]

[Prior art]

 In recent years, the environmental issues surrounding us have been highlighted, especially the disposal of large amounts of garbage from our lives. On the other hand, it is also important to cherish precious earth resources and to use them effectively without waste.

At present, many purchased products, particularly vegetables and other small miscellaneous goods, are generally packaged in a bag made of a synthetic resin film such as polyethylene for convenience of carrying. The packaging bag made of the synthetic resin film is distributed and used in an extremely large amount, and is a valuable material excellent in various performances including the tensile strength. These valuable packaging bags are often discarded as garbage after bringing home the goods.

[0004] It is necessary and important to reuse this precious packaging material effectively, and a number of small holes are made in this synthetic resin film bag to make a commercially available kitchen garbage drainer net. Use as a substitute is the most effective method, and it also contributes to resources.

[0005] However, it is not easy to make many holes at once in a bag made of a synthetic resin film having excellent tensile strength and tear strength. A device for making a hole in a synthetic resin film for such a purpose has already been proposed, and a device for making a hole by pressing a large number of needles or a plate-like body having a sharp tip (see FIG. 2) can be found. There is no satisfactory product that may cause injuries due to needles or sharp projections, and some that cannot easily remove the perforated synthetic resin film from the device. .

[0006]

[Problems to be solved by the invention]

 The present inventor has conducted research on the development of a handy punch that can easily and safely and easily form a large number of small holes, and has completed the present invention.

[0007]

[Means for Solving the Problems]

 The present invention has a shallow box-shaped lid having a large number of drilling needles standing in a downward direction, and a large number of holes through which the multiple drilling needles penetrate. A piercing member comprising a piercing needle cover plate coupled to the box-shaped lid and an elastic member so as to cover the piercing needle, and a plurality of piercing needles into which the plurality of piercing needles penetrate when being engaged with the piercing member. The present invention provides a safety punch for a synthetic resin film, comprising: a perforated member having a hole; and a receiving table hinged on one side.

[0008]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail. The size of the punch of the present invention is not particularly limited.However, a hole is made in a synthetic resin film shopping bag distributed at stores for the purpose of draining kitchen garbage and preparing bags for storing kitchen waste. As a convenient box, a box-shaped box having a width of 5 cm to 10 cm, a length of 15 cm to 20 cm, and a thickness of about 2 cm to 5 cm is convenient and suitable for carrying and handling.

Next, details of the structure will be described with reference to the accompanying drawings. FIG. 1 is a side sectional view of an example of the punch of the present invention. The punch has a shallow box-shaped lid 2 having a large number of piercing needles 5 and a through hole 6 through which the plurality of piercing needles 5 penetrate. The punch is the box-shaped lid 2 and an elastic member. A drilling member 1 consisting of a drilling needle cover plate 3 connected so as to be located immediately before (in the drawing, below) the tip of the drilling needle via a conical coil 7 and a butterfly formed by the drilling member 1 and the shaft 8 And a cradle 4 having a penetrating hole 9 through which the large number of piercing needles 5 penetrate when engaged with the piercing member 1.

[0010] Instead of the conical coil spring 7, a plate-like porous synthetic resin elastic body such as a sponge may be used. Alternatively, the perforating needle cover plate 3 can be made of a metal net through which the perforating needle 5 penetrates. The drilling member 1 may be provided with a handle 11 for easy operation. When the drilling member 1 and the pedestal 4 are hinged, the drilling operation can be facilitated by disposing the bent leaf spring 10 so that the two maintain a fixed angle. In addition, as a means for hinged, the drilling member 1 and the pedestal 4 can be combined with a bending-resistant synthetic resin plate such as a polypropylene resin plate to replace the hinge. In addition, it is also possible to equip the piercing member 1 and the receiving table 4 by providing the locking members 12 and 12 'so that the punching member can be conveniently stored when the punch is not used. By attaching the cushioning rubber plate 13 to the bottom of the pedestal 4, the punch can be prevented from slipping and the drilling operation can be performed smoothly and without damaging the table surface when used on a table.

Next, in order to form a hole in the synthetic resin film, the synthetic resin film 14 to be formed is placed and sandwiched between the piercing member 1 for opening the hole and the receiving base 4, and the piercing member 1 is pressed from above. And make them bite. The synthetic resin film 14 and the piercing needle cover plate 3 come into contact with each other. When the piercing needle cover plate 3 is further pressed, the conical coil spring 7 is compressed by the pressing force. Drilling needles protrude from the through holes 6 of the plate 3 and pierce the synthetic resin film 14 to make holes as small as the number of needles at a time.

Then, when the pressing force is released, the conical coil spring 7 pushes back the piercing needle cover plate 3, and at this time, the piercing needle 5 naturally comes out of the synthetic resin film 14 at the same time. Next, the boring member 1 and the cradle 4 are opened to a certain angle and stopped by the repulsive force of the bent leaf spring 10. As is clear from the above description, during the drilling operation, the drilling needle 5 is covered with the drilling needle cover plate 3 and is not exposed, and after drilling, the drilling needle is made of an elastic member such as a conical coil spring and the drilling needle. Since the cover plate 3 can be pulled out of the synthetic resin film without any effort, the perforated film can be easily removed from the punch, and the holes can be formed safely and easily and reliably. FIG. 2 shows a known synthetic resin film drilling device.

[0013]

[Effect of the invention]

 As is clear from the above description, the punch of the present invention can easily and easily make many holes in various synthetic resin films such as polyolefin film and polyvinyl chloride film at one time, and may cause injury. Also less. Therefore, this bag is reused as a bag made of synthetic resin film, which is used in large quantities for packaging products, and is used as a drainage bag for cooking waste such as cooking waste. It is very useful for recycling as a bag, and it is also useful for reusing resources.
