DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the packaging of films such as wrap film for food packaging, cooking paper for cooking and aluminum foil.

[0002]

2. Description of the Related Art Retail products such as wrap films for food packaging, cooking paper for cooking, and films such as aluminum foil have a one-pattern fixed idea and a maker's side in their product forms and packaging containers. There are some commonalities and associated shortcomings that seem to have been created by logic. (A) The product form of the film is such that the film, which is a product, has a core of a paper cylinder having a diameter of about 3 to 4 cm.
It is wound about 0 meters. Compared to the thickness of the core tube, the thickness of the winding of the film body is thinner, and the feeling of raising the product is undeniable. (B) All paper boxes as packaging containers are made to be disposable. It is important to protect and respect resources by discarding unnecessary films each time only about 20 meters of film is used up. Being a wasteful user who goes against (C) Paper boxes as packaging containers should be
Since it is designed to be used as a cutter case, a method of attaching a saw-shaped metal band to a paper box is used. However, because the packaging container is disposable and there are restrictions on costs, the paper box itself is also poor and lacks the robustness that is rugged as a cutter case, and the cutter function is halfway and difficult to use. (D) These films are often packaged together in small drawers or storage shelves around the worktop and taken out as needed. There is a high risk of injury from hands or fingers when removing or storing the metal strip because the cutter is exposed. (E) In addition, in order to properly recycle paper boxes of packaging containers that are no longer needed, at the time of separate discharge and separate collection,
It is necessary to remove the metal band of the saw-shaped cutter from the paper box in advance, which is troublesome and hinders proper recycling.

[0003] Since the cutter function is halfway and difficult to use, some manufacturers have tried to improve the usability by devising the shape and mounting location of the cutter of the saw-shaped metal strip, but the paper box of the packaging container and the It has not escaped from the conventional idea of also using the cutter case, and it does not seem that the cutter function and safety have been effectively improved. Also, from the perspective of meeting the demands of resource conservation and recycling, the disposable method has been adopted each time,
No consideration is given to resource saving. In addition, little improvement has been made in the points that hinder the enforcement of resource recycling and separate collection, such as a foreign metal cutter being firmly fixed to a paper box. For this reason, drastic improvement must be considered first, as it breaks away from the conventional idea of using the paper box of the packaging container and the cutter case at the time of use.

[0004] Paper boxes as conventional packaging containers use opaque cardboard, and although the film capacity is indicated on the outside, for example, 15 meters or 20 meters, the state of the inside of the box in any state. You can't buy it by checking in advance to see if it fits in. In addition, it is not possible to continually use the opaque container to check how much is left on the way, and it is not possible with the conventional opaque container. I am used to the habit of doing it.

[0005] Films wound around the core tube, when used,
By being rotated together with the core tube in the packaging container, the core tube is pulled out of the packaging container. At this time, in order to make the rotation smooth, it is necessary to take structural considerations to function as a bearing for supporting the rotating shaft of the core cylinder. However, no such structural considerations have been made. Since the packaging container is disposable, it is considered that the structural processing which increases the cost is omitted. Instead, it seems that the intention was to increase the thickness of the core cylinder disproportionately to the film capacity to facilitate rotation in the packaging container.

SUMMARY OF THE INVENTION With the diversification of cooking methods in modern eating habits and the advancement of food preservation methods, films such as wrap films for food packaging, cooking paper for cooking, and aluminum foil are becoming widely used. Despite this, no drastic improvement has been made in the form of the product, the style of the packaging container, the usability of the cutter function, etc., and as a result, many users listed in the previous section. Not only is it inconvenient, but it also hinders the demands of the times to respect resources and enforce recycling. The present invention has been made in view of such an absurd situation, and brings many advantages to users and society widely, such as convenience, safety, economy, resource saving and recycling as described below. In addition to providing packaging containers for new ideas, it will also provide ideas for the market for films such as wrap film for food packaging, cooking paper for cooking, and aluminum foil to encourage radical improvements in commercialization policies.

First, the basic concept of the present invention will be described below. (A) Current packaging containers, such as wrap film for food packaging, cooking paper for cooking, and films such as aluminum foil (hereinafter referred to as films), are made on the premise of disposable, and have an added cutter function. Are also simple and crude. The source of the absurdity mentioned above is:
First, we will radically revise this stereotyped idea because it comes from a commercialization policy that combines the use of disposable packaging containers and cutter cases. (B) For this reason, we first break away from the idea of "disposable" and halfway "double use". As a cutter case, we will develop a cutter case that thoroughly studies functionality, safety, durability, and other usability, and sells standard-size film products in this set. Separately, standard-capacity film products for refilling and refilling will be sold together in thorough simple packaging. (C) The user first purchases a cutter case in which a standard-capacity film product is set. Conventionally, an initial cost is required, but a convenient and convenient cutter case that is semi-permanently usable thereafter can be repeatedly used. At the time of replenishment, the initial cost can be easily recovered because it is sufficient to purchase a refillable standard-size film product whose cost has been rationalized by simple packaging. As a matter of course, every time a purchase is made as in the past, wasteful use of paying for the disposable container is eliminated, and the trouble of disposal is eliminated. (D) The method of selling the film products in the cutter case and the film products for refilling and refilling is standardized for the structure, material and size specifications of the cutter case for each type of film in cooperation with each manufacturer. And
For film products for refilling and refilling, standardization of specifications such as size (width), capacity (length), and core tube thickness (inner diameter) has been made so that film products from any manufacturer can be refilled without any problem. It is desirable to do. The reason is that by unifying the structure, material and size specifications of the cutter case, the cost can be reduced by mass production. Also, by using the same specifications for refill and refill film products, pure quality-oriented competition between manufacturers will be promoted, and as a result, the quality level will increase.

Next, the basic concept relating to commercialization of the cutter case of the present invention described in claim 1 will be described below. (B) To ensure that the quality, function, and usability of the cutter case do not deteriorate even after repeated use over a long period of time, the structure and material should be robust and durable. (B) Applying materials and manufacturing methods capable of effective cost reduction by mass production, and pursuing a structure and part design that can simplify secondary processing such as assembly. (C) Transparent and suitable plastics are desirable as the material so that the state of the contents such as the remaining amount can always be observed from the outside of the cutter case. (D) Since films used for food or cooking are always stored, appropriate antibacterial plastics are desirable as the material. (E) Basically, by manufacturing a plurality of plastic parts in a form that is easy to injection mold, and assembling them,
In the end, all parts will be made of the same plastic material in consideration of disposal and recycling, and different materials will not be mixed except for springs and cutters that can be easily attached and detached. (F) Regardless of whether it is used or not used, the structure shall be designed with safety in mind so that hands and fingertips do not accidentally touch the cutter. (G) On both end walls inside the case, cylindrical projections having a size that fits the inner diameter of the core tube of the replenishing film are provided, and the refilling film is set therein. This cylindrical projection makes it possible to increase the capacity (length) of the supplementary film in order to constantly improve the rotation of the core cylinder in the case. (H) Taking this opportunity, it is desirable to standardize the inner diameter of the core tube of the replenishing film to, for example, 30 mm, and increase the capacity of the replenishing film to about 100 meters at a stroke. (I) Since the width of films is standardized mainly to 30 cm and 20 cm, it is desirable to standardize the size of the cutter case of the present invention in accordance with these film widths.

Next, the cutter case (reference numeral 4) of the present invention.
The structure and the shape of the assembled parts will be described below with reference to the drawings and reference numerals. (A) The overall structure is the case body (reference numeral 6) and the cutter upper lid (reference numeral 5) shown in the drawings of FIGS.
And a pair of left and right sideboards (symbol 7) for setting a film core tube (symbol 3). One of the sideboards is fixed to the case body, and the other is temporarily removable when setting the film. To do. (B) The cutter upper lid (reference numeral 5) includes a cutter upper lid body that opens and closes at the upper part of the case body (reference numeral 6), a cutter holder (reference numeral 8) that moves up and down by a spring when pressed when used, and a cutter upper lid main body. And a pair of right and left fixed guide boards (reference numeral 11) for guiding the movement of the cutter holder in the above. (C) The cutter holder (reference numeral 8) is provided with a cutter (reference numeral 9) at the lower end, and a spring (reference numeral 10) is provided above the spring for pushing up the cutter when not in use for safety. I do. (D) The cutter (reference numeral 9) has a saw-shaped knurled blade shape as shown in the enlarged view and the enlarged sectional view of FIG. 10, the tip of the blade is sharpened sharply, and the material is a book. A metal that is resistant to abrasion, durable, and maintains sharpness for an extended period of time is desirable, consistent with the objects of the invention. (E) In the conventional film product, the film wound around the core tube is extremely thin, and the feeling of raising the bottom is undeniable. For the purposes of the present invention, the film volume (length) should be sufficiently usable. The inner diameter of the core tube (reference numeral 3) is the sideboard (reference numeral 7).
It should be standardized to a size that smoothly fits the outer diameter of the bearing projections.

Next, how to use the cutter case of the present invention will be described below with reference to the drawings and reference numerals. (A) In the method of setting the film product (reference numeral 1) in the cutter case (reference numeral 4) of the present invention, first, as shown in the sectional views of FIGS. The side board (reference numeral 7) which can be opened and detached is removed, the film product (reference numeral 1) is set in the case, and the removed side board (reference numeral 7) is returned to the original position. (B) In order to use the present invention as a cutter, first, as shown in the cross-sectional view of FIG.
Is pulled out of the case, and the upper cover (reference numeral 5) of the cutter is closed. Next, the upper part of the cutter holder (reference numeral 8) may be pushed while the cutter case (reference numeral 4) is tilted and slightly pulled while pulling the leading end of the film. In addition, the tip of the film after cutting stays outside the case with the contact part between the case main body (reference numeral 6) and the cutter upper lid (reference numeral 5) kept, so it is hygienic and convenient for the next use. It is. This eliminates the inconvenience that often occurs in the conventional paper box case, in which the leading end of the film returns to the inside of the box and it is not possible to know where to take out the film at the next use.

[0011]

Advantages and effects of the present invention will be described below in comparison with conventional wrap film products. (B) It is assumed that a wrap film having a capacity of 20 meters is now sold at a market price of 200 yen, and a user has bought and used it. The purpose of the user's purchase is to use the food in the kitchen of my home for temporary storage in the refrigerator, freezing, heating in a microwave oven, etc. They invest 10 yen per meter. (B) On the other hand, the seller sells the market price of 200 yen including the purchase cost from the manufacturer and the sales margin. (C) In addition, the manufacturer's wholesale price includes manufacturing profits, sales promotion costs, logistics costs, and manufacturing costs, and the manufacturing costs include the cost of paper boxes with cutters in a significant proportion. I have. If these are all deducted from the market price of 200 yen, it is hard to imagine that the factory cost of the manufacturer's wrap film is extremely insignificant. (D) Moreover, compared to general paper box packaging containers, the packaging container for wrap film also has a cutter function, so it has a saw-shaped metal cutter and the structure of the box is complicated.
Obviously, the cost is high, and users pay for the cost, and every time they use up only 20 meters of wrap film, the cutter / carton container becomes useless and is discarded. (E) If the user uses this wrap film two times a day, the user will consume 730 meters of wrap film in one year, but at the same time, three years
This means that six paper box containers with cutters are discarded. This means that not only the individual user wastes money economically, but also the manufacturer of the product, as a result, promotes an environment that wastes waste and hinders resource recycling. The absurdity that goes against national resource conservation and recycling trends is left unchecked. (F) Therefore, the effect of the present invention is that, when viewed broadly, many of the absurdities that have been neglected as described above can be drastically eliminated.

Next, the advantages of the present invention will be described below. (A) The usability and sharpness of cutting are much better than a rough and incomplete paper box that also serves as a cutter. (B) It is made of a material with excellent quality and durability and has a robust structure, so it can be used repeatedly for a long time. (C) Regardless of whether it is used or not used, the structure is such that the blade edge of the cutter does not touch hands or fingers unless the cutter holder is disassembled independently, so it can be used safely and safely. (D) Since the case is made of a transparent material, you can check the status of the contents, such as the film capacity, before you buy it, and also check the remaining amount during use. You can use it. (E) The dedicated cutter case requires initial costs at first, but only needs to buy the replenishment film product, eliminating the wasteful cost of disposable containers as in the past. , The overall economic effect increases. (F) Every time a film is purchased, the trouble of discarding the paper box container with the cutter is eliminated, and the trouble of removing the metal of the cutter and separating and discharging each time is eliminated.
