Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency opener for use in opening a confectionery bag.

[0002]

2. Description of the Related Art Conventionally, in order to open a confectionery bag, the bag is opened by tearing it from a notch provided at the end of the bag, or by pulling a bag without a notch near the edge of the bag at right angles to the edge. It was done with scissors.

[0003]

[Problems to be Solved by the Invention] When opening a snack or confectionery bag at a travel destination or in a train, the bag is torn in an unexpected direction from the notch, or the notch is stretched so that it cannot be torn and cannot be opened. Can be troubled. An object of the present invention is to solve such a problem, and an object of the present invention is to provide an emergency opener capable of easily opening a bag, having excellent portability, safety, and design.

[0004]

[Means for Solving the Problems] In order to achieve the above object, the emergency opener of the present invention is a curved gap, which is a linear gap having a U-shaped curve on the surface of a card-shaped plate (1) such as a card-shaped thin plastic plate. A slit (4) is cut out thereby to form an area of a concave portion (2) and a convex portion (3) above and below the slit, and near the left and right inner ends of the slit,
A serrated cutter (5) is provided. 2. In order to achieve the above-mentioned object aesthetically and happily, the shape of the curved slit (4) on the surface of the card-shaped plate (1) according to the present invention according to the present invention is regarded as the mouth of a human or an animal, and the size and the position are determined. It is characterized in that a pattern of a person or an animal which fits the slit, and a pattern of a person or an animal whose mouth is like the slit (6) is provided by a print, a seal, a relief, or the like. 3. In order to attain the above object precisely, a protuberance (7) having a hill-like thickness or a plate-like thickness is provided on a portion of the saw blade-shaped cutter (5) of the present invention according to claim 1 or 2, and has a saw blade shape. The present invention is characterized in that the effective thickness of the blade edge of the cutter is increased, or a high-strength cutter plate is attached, thereby enhancing the performance of the saw blade cutter.

FIG. 6 is a cross-sectional view taken along the line CC of the third embodiment. FIG. 7 shows the third embodiment.
It is DD sectional drawing of. FIG. 8 is an explanatory diagram showing a state during use of the present invention. FIG. 9 is an explanatory diagram of a swelling portion of the third embodiment. FIG. 10 is an explanatory view of a raised portion when the raised portion (7) and the saw blade-shaped cutter (5) are formed of a high-strength plate and provided by bonding.

Hereinafter, the emergency opener of the present invention will be described. In the first embodiment of the present invention, (1) is a card-shaped plate. It is an ordinary credit card-sized thin plastic plate. The plate is divided into concave portions (2) in a plane direction (up and down directions in the embodiment).
A curved slit (4) having a U-shaped narrow curve is provided so as to form a portion of the convex portion (3). Before using the card, slightly shift the sides of the concave and convex portions that were on the same plane before use, open the mouth, and make the edge of the bag to be opened almost parallel to the concave and convex surfaces. It looks like it can be clipped. When inserting the bag, it has a smooth rounded curve so that it can be done smoothly without getting caught. In the vicinity of the inner end of the slit, there is provided a saw blade-shaped cutter (5) formed like a saw blade like the edge of a cellophane tape cutter. The cutting edge of the cutter is a planar saw blade acute angle or a three-dimensional acute angle (8) that forms an acute angle in both plane and cross section. The former is appropriate when the plate is cut in a thin card shape and the latter is appropriate when the plate is integrally molded. (1)-of this embodiment
(5) is formed by integral molding. Embodiment 2 of the present invention
Then, on the surface of the card-shaped plate (1) of the present invention described in the first embodiment, the shape of the curved slit (4) is regarded as the mouth of a human or animal, and the size or position of the human or animal matches the slit. The pattern (6) of a person or an animal whose slit is likened to a mouth is provided with a print, a seal, a relief, or the like. In the third embodiment of the present invention, a ridge (7) having a hill-like thickness is provided in the saw blade-shaped cutter (5) portion of the present invention described in the first or second embodiment to reduce the effective thickness of the cutter portion. Enlarging the performance of the saw blade cutter. As shown in FIG. 9, the cutting edge of the cutter has a three-dimensionally enhanced strength in the form of an inclined waveform cut off horizontally at the bottom surface. By keeping only this part thick while keeping the card-shaped plate in a thin plate shape, a three-dimensional acute angle is formed at the saw blade-shaped cutter part while securing the flexibility and thinness of the whole card. Easy and high-performance cutter function can be obtained. In the embodiment, the plane has a substantially semicircular shape so that there is no sense of incongruity, and a gentle curve rises. The structure of the swelling part is made by integrally molding the entire part including this part and the swelling part including the saw blade cutter as a separate part, pasting, heat sealing, attaching by means such as fitting, and attaching this part. Form.
As shown in FIG. 10, the protuberance (7) and the saw blade-shaped cutter (5) may be formed of a high-strength plate such as a stainless steel plate and adhered. When a high-strength plate such as a metal plate is used in (7) and (5), as shown in FIG. It is preferable from the viewpoint of safety to bend the cutting edge toward the inside of the hole. In the case where a pattern of a person or an animal is provided as in the second embodiment by providing a climax, the cuteness is increased by treating the climax as a smile. (9) is a clearance space. With the edge of the bag to be opened inserted in the curved slit,
Due to the thickness and angle of the card, a clearance space that releases the complex stress of the bag trying to break in the shape of a crank to prevent the bag from becoming cramped near the edge in the vicinity of the edge Is provided so that the edge of the bag can be easily inserted into the fixed position at the back.

Next, an example of use of the emergency opener and its operation will be described. The method of use of the present invention is to remove the bag of snacks and confectionery at a travel destination or in a train, etc., take out the present invention from a wallet or card case, etc. Open your mouth. With the edge of the bag to be opened slid into the open mouth, hold the card together with your finger, and hold the portion of the bag that begins to sever to the saw blade. Then, with the other hand, touch the edge of the bag to the blade of the cutter, pull it, make a cut in the edge of the bag, and cut the bag.

[0008]

As described above, according to the emergency opener of the present invention, it is possible to easily break the bag of snacks and confectionery when opening the bag of snacks and confectionery in places where there is no scissors, such as on a travel destination or in a train. Can provide an aesthetic image opener, in card form. Because it is a regular credit card, you can always keep it close by putting it in a wallet, card case, etc., and use it immediately when you need it. In addition, by storing the blade edge portion of the cutter inside the card, it is possible to eliminate the danger of, for example, damaging the human body while carrying the card. Easy operability, portability always close, safety that the cutting edge fits in the card,
And there is the fun of the design that combines the cuteness with the practicality that looks like a curved slit to the mouth of a person or animal. The present invention provided with the bulge (7) can further enhance the performance of the saw blade cutter as described above, and also produces a design-like fun that looks like a smile. Since the present invention has a simple structure, it can be easily produced, and the production cost can be reduced.
