Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a polyvinylidene chloride film and aluminum foil wound around a paper tube and housed in a container having a cutting means. and a pair of orbital-shaped perforations, and a slit in the front plate into which the tongue piece can be inserted, and when the tongue piece is completely inserted into the slit, the eyeball enters the eye socket and the rolled film forms a lively face. Regarding paper boxes with faces.

[Conventional technology]

Conventionally, wrapped films such as wrap films and aluminum foils are wound around paper tubes and stored in horizontally long paper boxes, and the required amount is unwound from the end, and cut using a cutting means such as a metal serrated blade attached to the paper box or an abrasive surface. It was cut and used.

In particular, polyvinylidene chloride-based films are thin and self-adhesive, tend to adhere to each other, and have low tear propagation strength and tear with the slightest scratch, making them difficult to handle. Therefore, various means have been proposed for improving the following performances of polyvinylidene chloride film containers.

(a) Improved cutting performance and sharpness; (b) Safety with no risk of injury due to the cutting blade; (C) Sealing performance. Since the product can be used for food even after opening, it is used unsealed from a hygienic standpoint. It is preferable that the container is kept as tightly sealed as possible even after the start.

(6) Prevention of entrainment: Polyvinylidene chloride film is thin and highly self-adhesive, which prevents the inconvenience of the cut end wrapping around the wound film and making it difficult to pull out the cut end for next use. To prevent.

(e) Preventing the paper tube from popping out: Prevents the inconvenience of the film popping out along with the paper tube when the film is pulled out forcefully.

(f) Ease of unwinding, (El　Ease of manufacturing paper boxes, etc.)

In Japanese Patent Application No. 1-315394, the present applicant proposed a method of solving all of the above problems at the same time by providing a tongue piece at the tip of the cover and providing a slit in the front plate into which the tongue piece as a cutting means could be inserted. I proposed a paper box for film.

[Problem to be solved by the invention]

The present invention further improves the above proposal, and when the required amount of the wound film is unwound and the tongue piece is inserted into the slit, it can be confirmed that the perforation for starting cutting has occurred in the wound film. To provide a paper box for a rolled film provided with a means.

[Means of problem solving]

The structure of the present invention is such that a front plate, a bottom plate, and a rear plate are sequentially connected via a ridge line, and a lid body extends from the upper end of the rear plate of an elongated box body, which is formed by fixing approximately square side plates to both sides. , in a paper box made of a rolled film in which a cover piece that overlaps with the front plate extends from the tip of the cover body, the cover piece has a shape that has the widest protrusion at a part other than both ends, and the periphery of the protrusion is arranged along the ridgeline of the paper box. At the same time, a tongue piece in which the wound film is perforated is protruded from the protruding part, a pair of perforations are provided in the upper part of the tongue piece to form an eye socket shape, and the tongue piece can be inserted into the front plate. A slit is made, the tongue piece is inserted into the slit, and a perforation is created in the center of the rolled film, so that a pair of dark eyeball-shaped colored parts previously provided on the front plate are inserted into the orbit of the cover piece. enter,
It is characterized by forming facial expressions and lively faces.

As the wound film in the present invention, a polyvinylidene chloride film wound around a paper tube, aluminum foil, or the like is preferably used.

The paper box that stores these rolled films is a horizontally long box with a rectangular front plate, bottom plate, and rear plate fixed by approximately square pieces on both sides.A lid extends from the upper end of the rear plate, and a cover extends from the end of the lid. A shape with extended pieces is common. However, the triangle
You can choose any cross-sectional shape, such as a triangle with rounded corners, a polygon, a circle, or a semi-cylindrical shape.

The cover piece is required to have a protruding shape that is widest at a portion other than both ends, preferably at the center, and the periphery of this protrusion is inclined and gradually becomes narrower. However, this inclination does not necessarily have to be provided over the entire cut end of the cover piece, and it is sufficient to provide the inclination approximately 3 to 5 cm each around the protrusion.

As the cutting means, a tongue piece is made to protrude from the above-mentioned protrusion.

The tongue piece is not particularly limited, such as a metal plate, a plastic plate, a paperboard reinforced with resin or a mixture of resin and inorganic powder, a thin ceramic plate, etc., and is a thin hard material that can be perforated in the film, preferably horizontally long perforations. Any tongue-shaped protrusion consisting of the following may be used. When using a particularly sharp material such as a metal plate, it is better to have a slightly rounded tip for safety reasons. Further, in order to smoothly insert the tongue into the slit, it is preferable that the tongue be inclined inward at the center. When providing such a tongue piece, the tongue piece may be attached to the protruding part of the cover piece using an adhesive,
In the case of a metal plate, etc., it can also be directly fixed using flattening, caulking, etc.

A pair of perforations are provided in the upper part of the tongue of the cover piece with the tongue in the center. This perforation has the appearance of an eye socket, and the tongue piece forms a tongue, forming a hollow face.

A slit is made in the front panel of the paper box. This slit is provided at a position where the tongue provided at the tip of the cover can be inserted.

Further, a pair of eye-shaped dark colored parts such as black, brown, or indigo are provided on the front plate at positions corresponding to the pair of perforations in the cover piece when the tongue piece is inserted into the slit.

Therefore, by simply opening the cover piece, unrolling the necessary amount of film, and inserting the tongue piece into the slit, the eyeball-shaped colored part of the front plate will fit into the eye socket-shaped hole in the cover piece, and it will become a simple eye socket. The shape changes to the shape of a lively face. At the same time, perforations are made in the film, and by simply pulling the box away from the film, the cut cut in the center of the film will be attached to the diagonally cut end of the cover piece. It can be guided and propagated and cut approximately perpendicular to the length of the wound film. After cutting, the tongue piece is inserted into the slit, so the lid is completely closed, resulting in a good seal and hygiene. Further, since the cut end of the film is a crack that propagates, the actual strength of the edge of the film is improved.

In particular, polyvinylidene chloride-based films have low tear propagation strength, so when cut with a conventional sawtooth that has serrations on the entire surface, the cut end becomes serrated. When using this film, this serrated cut edge can become a tear initiation point and cause it to run inadvertently if a slight force is applied.

In such cases, general consumers tend to misunderstand that the strength of the film itself is low.

As in the present invention, if the perforation made in one place is guided by the inclined cut end of the cover piece, there will be no damage to the cut, and even if an undesired force is applied, there will be no serrated recess that should propagate. Because there are no cracks, it is difficult to tear and has increased apparent strength.

[Effect]

In the present invention, the cut end of the cover piece is sloped to have a sharp tip, and a tongue made of a thin hard material is attached to the tip so as to protrude, and the top of the tongue is placed in a position to sandwich the tongue. A pair of orbital holes were made.

On the other hand, a slit is provided in the front plate into which the tongue piece can be inserted, and a dark colored part shaped like an eyeball is provided above the slit.

As a result, when the tip of the cover is inserted into the slit on the front plate, the dark eyeball enters the eye socket of the cover piece, forming a lively face, and the rolled film between the front plate and the cover piece. That a break has occurred! IBM can. The cuts or perforations made in the film can be cut at once by simply pulling the box horizontally and vertically in the direction opposite to the direction in which the film is pulled out, guided by the inclination of the cut end of the cover piece. The cut edges of the cut film have no irregularities such as sawtooth shapes (and are smooth, so even if an unexpected force is applied during use, there are no scratches or irregularities to propagate, so it is difficult to tear.

Furthermore, since the box is opened only when pulling out the film, and is always closed in other situations, there is no risk of the film being contaminated with dust, etc., making it sanitary.
