[Prior art]
Conventionally, wrap cases have been proposed in the form of Japanese Utility Model Publication No. 52-35219 (plastic sheet packaging paper container) and Japanese Utility Model Publication No. 55-53460 (packaging) in order to improve the drawability of the wound film. As shown in Japanese Unexamined Utility Model Publication No. 60-148243 (storage container for packaging film), the front plate of the case is formed to be narrow. No. 61-188933 (aluminum foil roll container with a drawer opening), Japanese Utility Model Application Laid-Open No. 61-193015 (a wrap film roll container with a drawer opening), and Japanese Utility Model Application Laid-Open No. 4-89934 (a wrap film take-out opening). To prevent unintentional popping out of a bent piece having a fold or a roll-shaped film JP-B-53-48193 (paper container for wound film) and JP-A-2-152650 (roll-restricted dispensing container) are also mentioned. There is also a proposal to apply a varnish.
According to the above-mentioned known example, although a tentative solution is presented for a specific problem, it is still a proposal to solve the problem all at once with respect to the film drawing property, the prevention of rewinding, and the roll-out film jumping out. It could not be denied that there were points that had not yet been evaluated, and that there were points to be solved in terms of economics in terms of robustness and manufacturing cost.
[0003]
[Problems to be solved by the invention]
The present invention improves the drawability of a roll-shaped film by forming a film holding piece and a pressing piece in a front wall portion and a folded portion of a conventional wrap carton, respectively, and prevents the film from rewinding and jumping out. Try to provide carton.
[0004]
[Means for Solving the Problems]
To specifically describe the means for solving the above problems, the wrap carton of the present invention is a carton body comprising a front wall portion, a bottom portion, a rear wall portion and both side wall portions, and a fold formed on the rear wall portion through a fold. In a lap carton with serrated teeth comprising a lid portion connected to the front wall portion, a pair of film sandwiching pieces are cut and formed above both sides of the front wall portion, and a fold portion having a fold between each cut lower end is formed on the front wall portion. A press piece protruding toward the fold portion is cut and formed at a central portion of the upper edge, and a fold portion excluding a section of the cut and formed film sandwiching piece and the press piece is formed in front. It is affixed to the inner surface of the wall portion, and the pair of film sandwiching pieces are cut and formed so as to face each other, and the cut lower end is creased between the front wall portion and the side wall portion. Not to reach, moreover, At both ends of the fold between the front wall and the folded portion, it is also preferable to cut molding the film nipping pieces such that the side edges engaging the drawer film.
[0005]
[Action]
As shown in FIGS. 3 and 4, when holding the end portion of the roll-shaped film and pulling it to a desired length, the both sides of the film are engaged with the film holding piece, and the pressing piece is inserted into the lower surface of the film. I do.
When the film is pulled out in this state, the upper edge of the lower part of the front wall and the pressing piece are in contact with the lower surface of the film, and the side edges of the film are cut off at both ends of the fold between the front wall and the folding part. The film is pulled out while touching. Since the upper edge of the front wall portion is at a low position, and the pressing piece enters the lower surface of the film immediately before being peeled off from the roll, the drawing of the film is stabilized, and the pressing piece prevents the roll from jumping out.
Further, after the film is cut, the film tends to rewind due to the impact at the time of cutting, but the film is held back by the film holding piece and the pressing piece.

【Example】
DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall development view from the front side, and FIG. 3, FIG. 3 is a sectional view taken along line AA of FIG. 3, and FIG. 6 is a sectional view taken along line BB of FIG.
[0007]
The wrapped carton shown in the drawings relates to a carton for accommodating a synthetic resin film wound in a roll shape on a paper tube for the sake of explanation. It illustrates a so-called food packaging wrap film that is drawn out from the ground and mainly used for packaging foods such as seafood, vegetables and fruits. Therefore, the present invention can be used not only for the film but also for aluminum foil, wax paper, and other roll-shaped packaging materials at home or stores.
[0008]
In FIG. 1, the carton blank of the wrapped carton of the present invention is made of rectangular cardboard, and the front wall 1, the bottom 3, the rear wall 4, and the main body side wall 13 are connected via a fold 7, and the carton main body is connected. It is a basic member to be configured. In addition, a cover part 5 and a front cover part 6 constituting a cover part are connected to the rear wall part 4 through folds 7 respectively.
Above both sides of the front wall 1, a pair of film holding pieces 8 are formed by cuts 10, and a space 7 between the lower ends 10 a of the cuts 10 is a fold 7 a between the front wall 1 and the fold 2. When the fold 7a is attached to the inner surface of the front wall 1, the fold 7a becomes the upper edge of the front wall 1 and is lower than other walls constituting the carton body.
On the other hand, at the central portion of the upper edge of the front wall 1, a pressing piece 9 protruding toward the folding section 2 is formed by a cut 11, and the folding section 2 excluding the film holding piece 8 and the pressing piece 9 is formed at the front. It is attached to the inner surface of the wall 1. The lower end 10 a of the cut 10 is provided so as not to reach the fold 18 between the front wall portion 1 and the front wall sticking piece 12.
[0009]
In addition, near the lower end 10a, which is both ends of the fold 7a between the front wall portion 1 and the folded portion 2, cut portions are formed so that both side edges of the film are engaged with the film holding pieces. Cutting in an arc shape enables a moderate engagement.
By cutting the shape of the holding piece 9 into a semicircle or an elliptical shape, a moderate resistance is given to the lower surface of the film.
The front wall part 1, the bottom part 3, the rear wall part 4, the cover lid part 5, and the front lid part 6 each have a front wall sticking piece 12 through a fold 18, and a main body side wall having a folding piece 14 through the fold 18. The part 13, the rear wall side wall part 15, the side lid part 16, and the front lid sticking piece 17 are extended.
In the drawing, 19 is a zipper wire for cutting, 21 is a cutting portion for opening, 20 is a saw-like tooth for cutting (see FIG. 2), and is attached to the front lid portion 6.
[0010]
In the assembling of the present invention, as shown in FIG. 2, the front wall 1 is set at a low position by folding the folded portion 2 inward at the fold 7a and attaching the folded portion 2 to the inner surface of the front wall 1. 8. The presser piece 9 is in a raised state. Further, the bottom part 3, the rear wall part 4, the cover lid part 5, and the front lid part 6 are sequentially folded through the fold 7, and at the same time, the rear wall side wall part 15 through the front wall sticking piece 12 attached to the back surface of the main body side wall part 13. Are laminated and attached, and the carton body is assembled.
Further, a front wall sticking piece 17 is attached to the back surface of the side lid 16 to assemble a wrap carton with a lid, and the roll film F is mounted in a fixed position. After that, the cutout portion 21 connected to the front lid portion 6 via the zipper line is overlapped and adhered to the front wall portion 1 to complete the product.
[0011]
At the time of use, if the cutting portion 21 is cut off from the zipper wire 19, the front lid portion 6 can be opened and closed freely. Therefore, the end portion of the rolled film wound as shown in FIG. When pulling out, the both side edges of the film are engaged with the film holding piece 8, and the pressing piece 9 is correctly inserted into the lower surface of the film (see FIGS. 3 and 4). Once the film has been drawn to the desired length, it will be cut with saw teeth 20 for cutting.
[0012]
The film holding piece 8 is opposed to the upper side on both sides of the front wall portion 1 by the cut 10 on the side end, and engages so as to hold the film F so that the film F can be pulled out reliably and normally, as shown in FIG. In this way, unintended rewinding of the film F can be prevented, and it is preferable that the film F is smoothly introduced and has a guiding function in the subsequent withdrawal by being formed into a semicircular arc as shown in the drawing. . Although not shown, the shape of the film holding piece 8 is not limited to the semicircular shape, but may be, for example, a trapezoidal shape. Anything having a guide function is acceptable.
[0013]
The presser piece 9 is formed by a cut 11 along the fold 7a at the center of the upper edge of the front wall portion 1. The shape of the presser piece 9 is a semi-circle, or a semi-circular arc that is rounded as a whole and is almost an ellipse. Optimally, it is in a shape.
As shown in FIG. 4, since the holding piece 9 is formed at the center of the upper edge of the front wall 1 set at a low position, the holding piece 9 is drawn out when the film F having adhesiveness and self-adhesion is pulled out. By inserting the holding piece 9 into the lower surface of the film F (see FIG. 6), the film F is peeled off from the roll in a preferable state while being pushed up from the lower surface direction.
[0014]
This proper peeling function is such that the front wall portion 1 is set at a low position and that the film holding piece 8 is held and introduced even when the roll-shaped film F is continuously used and the remaining amount of the film is reduced. And by the guide function until the final use.
Further, since the folded piece 14 extending inward through the fold 18 at the upper edge of the main body side wall portion 13 of the carton P is covered with both ends of the roll-shaped film F, the film F rolls and swings at the time of drawing. Even they have been deterred from jumping out.
[0015]
【The invention's effect】
Since the present invention has the above configuration, the following effects can be obtained.
{Circle around (1)} The film F is smoothly led out by the film holding piece 8 and has a guide function at the time of drawing out, and the rewinding of the residual film F which is likely to occur after the drawing film is cut due to the engagement resistance due to the holding together with the pressing piece 9. Can be prevented.
In particular, in the case of a wrap film for food packaging mainly made of polyvinylidene chloride or the like, because of its adhesiveness and self-adhesiveness, if it is pulled out once and then unwound without being able to make a normal cut, the entire film is incurred. The effect of preventing the rewinding of the present invention is beneficial because the wrinkles are generated and cannot be reused, resulting in waste.
{Circle around (2)} The film F to be pulled out is always pushed up from below by the holding piece 9 having a semicircular or oblong shape, so that the film is smoothly peeled off from the roll, and there is a possibility of peeling failure or oblique cutting. The film drawability is stable, and the roll can be prevented from popping out.
{Circle around (3)} In addition to the effects provided by the film holding piece 8 and the holding piece 9, the pull-out property of the film F because the front wall portion 1, which has increased strength due to inward folding of the folding portion 2, is set at a low position. Is more improved.
Moreover, since the film holding piece 8 and the holding piece 9 can be formed by the cuts 10 and 11, the existing equipment can be used as it is, and mass productivity and economic efficiency are enhanced.
