(Points of interest)
As shown in the perspective view of the conventional wrap film roll body container shown in FIG. 10 and the sectional view of the wrap film roll body container shown in FIG. The rolled body 2 is wound in a cardboard box 21 made of cardboard and the transparent resin film 20 having a width of 30 cm or 22 cm and a length of 30 m to 50 m is wound around the cardboard 21 made of cardboard. The container body 3 includes a front part 30, a bottom part 31, a rear part 32, and left and right side parts 34 and 34 that close both ends of the groove part 33 formed by the front part 30, the bottom part 31, and the rear part 32, which are set to a size that can accommodate the roll body 2. The upper lid 5 is continuously formed on the upper end edge of the rear portion 32 facing the opening 35 opened on the upper surface of the container body 3 via the rear bent portion 4, and the container body 3 front portion 30 facing the opening 35 of the upper lid 5. The nearest part beyond the edge becomes the front bent part 50, bent to the outside of the front part 30 of the container body 3, and straightly lowered by a dimension smaller than the height of the container body 3 to a predetermined width. When the wrap film 20 is used, the box-shaped container body 3 is held in one hand (not shown) when the wrap film 20 is used. Then, the roll body 2 end edge 22 accommodated in the inside is picked with a hand of the opposite side (not shown), a necessary amount is pulled out through the opening 35, and then the upper lid 5 is closed and restrained. The portion corresponding to the wrap film 20 is pressed against the film cutter 52 at the lower end of 51, cut into a tear shape, and used for packaging foods and the like.

    When the wrap film 20 roll body 2 accommodated in such a box-shaped container body 3 is pulled out with the wrap film 20 and the drawer end edge 22 facing outward, the roll body 2 itself has its axis (see FIG. 11, while rotating around, a phenomenon of jumping in various directions (up and down, front and rear, oblique, etc.) occurs as indicated by a one-dot chain arrow and a one-dot chain arc in FIG. If the opening 35 is not appropriately closed and adjusted, the roll body 2 often jumps out of the container body 3, or the film body 52 is kept floating on the bottom 31 by the pulling operation. After cutting, when the hand holding the upper lid 5 is released, the roll body 2 falls onto the bottom 31 and the wrap film 20 and the draw-out edge 22 are rewound into the container body 3, When it tries to pull out the edge 22 of the wrap film 20 again, it will be very difficult to find and pull out the edge 22 of the wrap film 20. In order to use it, it is necessary to remember a certain amount of points while failing several times (the wrap film 20 that has failed to cut is often not usable and must be discarded). As shown in FIG. 11, the edge 22 of the wrap film 20 after being cut by the film cutter 52 is brought into close contact with the outer wall surface of the front portion 30 by the pressing of the upper lid 5 front hanging piece 51 and used later. In some cases, the wrap film 20 end edge 22 is searched for and peeled off.

In order to solve such problems as the roll body 2 jumping out and the wrap film edge 22 rewinding into the container body 3, as shown in FIGS. 10 and 11, the container body 3 has an opening 35. On both or one of the upper end edge of the corresponding front portion 30 and the left and right side portions 34, 34, restraining flap portions 36, 36, 36 that are bent inward via a linear bent portion are integrally formed. It is assumed that the periphery of the roll body 2 plane shape is suppressed from the upper side, or the outer diameter dimension is set slightly smaller than the inner diameter of the paper cylinder 21 of the roll body 2 near the center of the left and right side portions 34, 34. It is assumed that the formed tongue-like portion is formed by a sewing machine hole excluding a part of the outer periphery thereof, and the user cuts and raises the left and right tongue-like portions into the container main body 3 so that the paper tube 21 Both ends There are commercially available products that are provided with pivoting tongues 37, 37 that are loosely fitted and rotatably supported. However, if the restraining flaps 36, 36, 36 are made too large. When rotating, the sliding friction is increased, which obstructs the smooth pulling operation of the wrap film edge 22, and the roll body 2 cannot be prevented from popping out if it is small. The supporting tongue pieces 37 and 37 have a drawback that if the roll body 2 has sufficient strength for pivotal attachment, the roll body 2 is prevented from rotating smoothly, and if the strength is insufficient, the roll body 2 cannot be popped out. In either case, the roll body 2 is inconvenient for taking out or mounting the roll body 2 from the container body 3, and it has not been an effective solution that can be satisfied by the user.
In the first place, as shown in FIGS. 10 and 11, the conventional roll body 2 container 1 having a rectangular cross-sectional shape is difficult to hold with one hand and is very difficult for children and women with small hands. It was difficult to use.

(Conventional technology)
In order to overcome such circumstances, for example, as in the invention described in Patent Document 1 (1) to be described later, it is possible to easily hold the container body as a shape connecting the front portion and the bottom portion with a curved surface. In addition, a “wrap film case” that can be used permanently by replacing the inner wrap film, or a horizontally long rectangle as seen in the “wrap film storage paper box” invention disclosed in Patent Document 1 (2) Between the bottom and the rear of the slab, a horizontally-long rectangular sloped plate is connected via a crease line, and the bottom rear corners of both sides of the left and right squares are cut diagonally and closely attached to the palm. And the container body as represented by the one that can reduce the amount of rewind due to the recoil when the film is cut, or the one proposed in Patent Document 1 (3). The front is empty inside the main unit As shown in “Patent storage box for roll-shaped film body” which is inclined inward so as to prevent the roll body 2 from popping out, and in Patent Document 1 (4). Such as a “wrap film storage box” that is provided with a cylindrical reinforcing portion that protrudes inward along the length direction of the inner surface upper end of the front portion of the container body 3 to prevent the roll body 2 from popping out. It is often seen.

However, either the bottom part and the front part as shown in the former patent document 1 (1) or the patent document 1 (2), or the bottom part and the rear part, or A roll container with an inclined surface or curved surface formed on either side can be easily gripped by children and women with small hands, but the bottom area is reduced, so it can be used on a table or shelf. When it was placed, it would be easy to roll over or fall over without being stable, and it would have the disadvantage that the usability deteriorates. Moreover, like what was indicated by the latter patent documents 1 (3) and the patent documents 1 (4) etc., the upper surface opening part of a container main body is made into a constricted top shape, or it is cylindrical at the upper end part of a container main body front part. In the case where the reinforcing part protrudes inward, the function of suppressing the roll-out of the roll body can be obtained, but the opening on the upper surface of the container body narrows, and the use of the wrap film drawer edge is accidentally started after opening or accidentally When it is caught in the inside of the wrap film, the wrap film edge is pulled out, so that the workability when removing and storing the roll body from the container body is greatly deteriorated. there were.

(Awareness of problems)
As described above, the containers for various wrap film rolls that have been proposed so far have polygonal cross-sections that are pentagons or more, or cross-sections that have curved surfaces in part so that they can be easily adapted to the palm. If the shape is set, the bottom area of the storage container itself will decrease, making it easier to roll over and fall, making it easier to use than conventional products in terms of placement on a table or storage shelf, and stability. In addition, the upper surface opening of the container body is reduced to prevent the accommodated roll body from popping out, or a cylindrical portion is formed at the upper end of the inner surface of the front of the container body. In such a case, the opening area of the opening on the upper surface is reduced, and the operability at the time of taking out and storing the roll body is deteriorated. In the situation that does not exist yet for the technology.

(Object of invention)
Therefore, the present invention is for a new wrap film that prevents the roll body from popping out, prevents rewinding of the drawer end edge after wrap film cutting, is easy to be gripped by a small palm, and can be stably placed. Judging from whether it is possible to develop a new container, we quickly started its development and research, and as a result of repeated trial and error over many years and many trials and experiments, this time, the wrap film finally has a new structure. The roll body container has been successfully realized, and hereinafter, the configuration thereof will be described in detail together with an embodiment representing the present invention shown in the drawings.

(Structure of the invention)
As will be clearly understood from the embodiments representing the present invention shown in the drawings, the wrap film roll body container of the present invention basically comprises the following configuration.
In other words, the front, bottom, and rear parts of the size restricted to realize a space suitable for accommodating a roll body in which a wrap film of a predetermined size is wound is closed, and both ends of the groove part formed by these are closed and used for stable stationary. Therefore, from the left and right side parts that are restricted to a rectangular shape or a rectangular shape whose bottom side length is equal to or greater than the maximum diameter of the roll body, the box is formed into a box-shaped container body having an opening portion by opening only the upper surface. From the rear upper end edge facing the opening, the upper end of the container main body facing the opening in the upper lid is formed by continuously forming an upper lid that can conceal the container main body opening by using the same edge as a rear bent portion. Folded to the outside of the front of the container body as the front bent portion at the nearest point beyond the edge, and formed into a front hanging piece that is linearly lowered by a dimension smaller than the container body height as it is and has a predetermined width, Apron While a film cutter is attached and formed over the entire lower end of the piece, the cross-sectional shape of the groove formed from the front, bottom and rear of the container body is at least near the boundary between the front and the bottom. The roll body accommodated in the groove portion is not grounded to the same bottom portion, and the suspended free end between the front hanging piece back surface and the inclined portion having a predetermined length or a curved portion having a predetermined curvature is formed. It is a wrapping film roll container that has a configuration in which the wrapping film drawing edge is restricted so as to secure a gap that separates from the front part.

    When the expression of the wrap film roll body container with this basic structure is changed and shown, the front part, the bottom part of the size restricted so as to realize a space suitable for roll body accommodation in which a predetermined size wrap film is wound, Only the upper surface from the rear part and the left and right side parts that are restricted to a rectangular shape or a rectangular shape whose bottom side length is equal to or larger than the maximum diameter of the roll body so as to close both ends of the groove portion formed by them and to be used for stable standing Is formed in a box-shaped container body having an opening as an opening, and an upper lid having a shape capable of concealing the container body opening from the rear upper end edge facing the opening as a rear bent portion. Consecutively formed, bent to the outside of the front of the container body as the front bent part at the nearest point beyond the upper edge of the front of the container body facing the opening on the top lid, and smaller than the height of the container body as it is It is formed into a front hanging piece that linearly descends by a certain dimension and has a predetermined width, and a film cutter is attached and formed over the entire lower end of the front hanging piece, while the front portion of the container body A groove section formed from the bottom portion and the rear portion, at least in the vicinity of the boundary between the front portion and the bottom portion, having a predetermined length oblique side or a curved portion having a predetermined curvature, and a roll accommodated inside the groove portion The body is not grounded to the same bottom part, and the gap between the front hanging piece back surface and the front hanging piece is restricted so as to secure a gap part that makes the hanging edge of the wrap film drawn out as the hanging free end from the front part, Regardless of the amount of wrap film drawn from the roll body, the play of the roll body in the container body is eliminated, and the position and posture of the wrap film drawing edge in the gap between the front of the container body and the back side of the front hanging piece are determined. Jisho the wrapping film roll container comprising a the configuration and made so as to ensure.

    According to the wrap film roll container of the present invention having the novel configuration as described above, in the conventional ones, there is a problem in how to store the wrap film drawer edge and handling processing, or because they dealt with them It has become a problem that the stability of the container itself is hindered, and the disadvantages such as deterioration of the operability of storing and removing the roll body in the container body have not been opened, but the front, bottom, Both ends of the groove part formed at the rear part are closed by the left and right sides restricted to a rectangular shape or a rectangular shape whose base length is equal to or greater than the maximum diameter of the roll body, and formed on a container body having an upper surface opening, and the rear upper end edge is bent back The upper lid is continuous through the section, and the nearest portion beyond the upper edge of the front portion of the upper lid is defined as the front bent portion, and is lowered to the outside of the container to be shorter than the height of the container main body. In order to prevent the roll body housed in the groove portion from being grounded to the bottom portion, the groove section formed from the front portion, the bottom portion, and the rear portion has at least the front portion and the bottom portion. A slanted side with a predetermined length or a curved part with a predetermined curvature is formed around the boundary between the front and the back of the front hanging piece. The gap should be regulated so as to be separated from the front, and the gap prevents the wrap film drawing edge from adhering to the front outer wall, and the film drawing edge from the next time onward is extracted. And the accommodated roll body is either between the oblique side having the predetermined length or the curved portion having the predetermined curvature and the rear portion, or between the oblique side having the predetermined length or the curved portions having the predetermined curvature. Crab hold So that the rotation axis of the roll body can be stably maintained when pulling out the wrap film, and the roll body can be bounced up and pulled out from the top opening as the wrap film is pulled out. In addition, it is easy to hold even a small hand of a child or a woman, and the lower ends of the left and right sides and the vicinity of the lower end surfaces are related to the shape and size of the hypotenuse of the predetermined length or the curved portion of the predetermined curvature. However, when the container bottom was firmly supported around the corners of the wrinkles and placed on a table, shelf, etc., it had not been solved so far, for example, to prevent inadvertent rollovers and falls. The excellent feature of being able to greatly improve handling in various scenes is obtained.

    In other words, a free end independent of the front end and the back side of the front drooping piece by securing a gap between the oblique side of the predetermined length or the curved portion of the predetermined curvature and the front dripping piece of the upper lid and the film cutter. In order to prevent the roll film from rotating, a slanted side with a predetermined length or a curved part with a predetermined curvature is formed at least around the boundary between the front part and the bottom part in order to prevent the wrap film from rewinding. A structure that prevents the center) from moving inside the storage container is essential, but the hypotenuse of the predetermined length or the curved portion of the predetermined curvature is effective, and the peripheral dimensions of the wrap film roll body storage container are reduced. Therefore, it can be surely grasped even by a hand of a small child or a woman, and it can be said that operability far superior to that of the conventional type can be obtained.

    In addition, the wrap film roll container that is formed with the cross-sectional shape of the groove formed from the front part, the bottom part, and the rear part of the container main body, while maintaining a right angle between the rear part and the bottom part, Only the boundary with the bottom portion is formed with a hypotenuse having a predetermined length or a curved portion with a predetermined curvature, and the above-described effects can be obtained without complicating the assembly structure and the manufacturing process.

    In addition, the cross-sectional shape of the groove formed from the front, bottom, and rear of the container body is such that a hypotenuse of a predetermined length or a curved portion of a predetermined curvature is formed between the rear and the bottom. The wrap film roll body storage container can hold the rotation center of the stored film roll body closer to the center of the storage container, and the outer peripheral surface of the film roll body has both oblique sides of the front and rear folds, a hypotenuse versus curved portion, It is balanced and held by any combination of the curved part versus the hypotenuse or both curved parts, which can prevent the film roll body from jumping and jumping more reliably, and the center of gravity of the entire container is placed near the center. Therefore, it can be more stably placed on a table or a shelf.

    Furthermore, the oblique side of the predetermined length or the curved portion of the predetermined curvature formed around the boundary between the front portion and the bottom portion of the container body is regulated so as to be arranged in a balanced manner from the center in the full length direction of the container body groove portion. The one formed in a range shorter than the total length can reduce the contact and holding area of the oblique side or curved portion to the outer peripheral surface of the film roll body, greatly increasing the contact resistance when pulling out the wrap film. This makes it possible to realize a lighter drawer operation.

    The upper lid has left and right hanging pieces formed downward at both left and right ends, respectively, so that the corresponding left side or right side can be attached to the outside, and the front part of each container body is at the end. The one that the edge is connected to the front hanging piece is that each left and right hanging piece connects the right and left ends of the upper lid and the left and right ends of the front hanging piece at a substantially right angle, so that the rigidity of the entire upper lid is increased, making it safer and easier In addition, the wrap film can be cut, and the upper lid closes the container body and opening more securely, further preventing intrusion of dust and insects, and more hygienic storage of the wrap film. Can be realized.

    In addition, the film cutter that is attached and formed over the entire length of the lower end of the front drooping piece has a cutting edge direction facing downward. Compared with this, it can be greatly simplified, more economical production can be realized and possible, and a structure advantageous for tearing the wrap film in the direction perpendicular to the front of the container body can be obtained. .

    Furthermore, the film cutter to be attached and formed over the entire length of the lower end of the front hanging piece is such that the blade edge of the film cutter is exposed to the outside when the blade edge direction faces the front of the container body. In addition to ensuring safety, the blade edge rigidity can be greatly increased when tearing the wrap film in the direction perpendicular to the front of the container body, in other words, the film. It can be said that this structure is advantageous for making the cutter thinner, lighter, and cheaper.

In implementing the present invention having the configuration as described above, the best or desirable mode will be described.
The roll body is formed by winding a resin film (wrap film) mainly intended for easy and sanitary packaging of food into a cardboard made of cardboard and laminating it. , Polyethylene terephthalate, stretched polypropylene, nylon (trade name), polyethylene, polypropylene, polyvinylidene chloride, polyvinyl alcohol, polyvinyl chloride, polymethylpentene, or a composite resin thereof. Sheets such as foil and kitchen paper can be replaced with those laminated in a cylindrical shape on a cylindrical body.

    The container body can accommodate the roll body from the opening on the upper surface, and when operated to pull out the wrap film from the roll body, the cylindrical peripheral wall surface below the center of the roll body is rotatable and stable. In order to perform the function to be able to hold, to block the front, bottom and rear of the size restricted to realize a space suitable for accommodating the roll body, and to close both ends of the groove formed by them, and for stable stationary use, From the left and right sides formed by regulating the bottom length of the roll body to be equal to or larger than the maximum diameter of the roll body, the box is of a box shape having an opening on the top surface, and at least the front and bottom portions. It must have a slanted side with a predetermined length or a curved part with a predetermined curvature around the boundary, and it must be able to be accommodated and held so that the roll body accommodated in the groove part does not come into contact with the bottom. , For example, it is of course possible external to those most things from previous consists cardboard box body as it is, and in some cases the resin sheet made of or metal sheet or resin molded products such as.

    The container body groove is a groove type surrounded by a container body front part, bottom part, rear part, left and right side parts, and at least a hypotenuse or a curved part with a predetermined curvature formed around the boundary between the front part and the bottom part.
