Abstract

PURPOSE:To prevent a roll core from jumping out and a wrap film from being rewound by a method wherein an inner lid formed with a cut trace by cutting a center part in an approximate U-shape along sawtooth directions is provided, and a protrusion is formed by making the tip center of an outer lid protrude while the protrusion is engaged with inside the cut trace of the inner lid when the outer lid is put on. CONSTITUTION:Approximately at the center of an inner lid 8, a cut part 11 by an approximately U-shaped cut slightly smaller than a protrusion 4 of an outer lid 3 is formed with a scored line 10 provided. At the time of use, an adhered piece 6 is peeled from the inner lid 8 while the adhered piece 6 is removed from the outer lid 3 along a scored line 5 and the outer lid 3 is opened upward, so that both scored lines are cut off to make the outer lid 3 free, resulting in free opening/closing of it. An end of a contained wrap film is drawn out along the upper face of the inner lid 3, and with the protrusion 4 pressed the wrap film is pulled along a front plate 7 and cut by a sawtooth 9 to be used.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement in a wrap film storage container, which aims to prevent the stored wrap film core from flying out and prevent the wrap film from unwinding, thereby improving handling properties. It was designed to improve hygiene.

(Prior art) When wrap film is used, if the tip of the wrap film is suddenly pulled, the roll core tends to pop out from the upper opening, and each time the wrap film is used, the roll diameter decreases and the inside of the container is pushed out. As a result of transfer, the exposed part is carelessly rewound into the container, making it necessary to search for the edge of the film when reusing it, making it inconvenient to handle. In most cases, the blade edge was pasted so that it slightly protruded forward from the front plate, and the end of the lamp film immediately after cutting was exposed to the outside to cover almost the entire surface of the front plate. (For example, Jikko 52-197
(See Publication No. 90).

(Problems to be Solved by the Invention) However, in the conventional structure described above, the problem of the roll core popping out remains unsolved.
When the leading end of the wrap film is suddenly pulled out, the core of the film often flies out from the opening.

Furthermore, if the tip of the lamp film is exposed to the extent that it covers the entire surface of the front plate, taking into account the amount of unwinding of the lamp film, it is unhygienic, resulting in wasted consumption, and the ease of use is poor, such as poor resealability. There was a flaw in the above.

(Means for Solving the Problems) The present invention solves the problems in the prior art described above, completely prevents the roll core from popping out, eliminates the unwinding of the wrap film, and improves hygiene and ease of handling. Specifically, it is housed in a rectangular box body that has a front plate, a bottom plate, a rear plate, and an outer cover that can be opened and closed in series, and has end plates that cover both left and right end faces. A wrap film storage device in which the wrapped wrap film is pulled out from the upper opening, held down by the outer lid, and cut with a saw blade attached to the front panel. In the container, a saw blade is fixed to the upper opening so that approximately half of the opening is covered from the front plate side, and the cutting edge slightly protrudes from the front plate, and the central part is approximately U-shaped in the direction of the saw blade. In addition to providing an inner lid with a notch to form a resection mark,
The present invention relates to a wrap film storage container in which a central portion of the tip of an outer cover is made to protrude to form a protrusion, and the protrusion is locked inside the cutout portion of the inner cover when the outer cover is closed.

(Function) First, open the outer lid, find the end piece of the wrap film housed in the container to take out, pinch the end piece and pull out the required length along the top surface of the inner lid, and then Cut the outer cover with a saw blade without holding it down, or push the protruding part of the outer cover through the wrap film into the cutout part of the inner cover to completely fix the wrap core, and then pull out the wrap film. Pull it in the direction along the front plate and cut it with the saw blade.

After cutting the wrap film, press the outer cover as described above or push the protruding part of the outer cover into the cut-out part of the inner cover, so that the part of the lamp film above the cut-out mark is placed on the surface of the rolled film inside the box. When pressed, self-adhesion occurs and the film is prevented from unwinding, but in addition to this, the protruding part of the outer cover, together with the tip of the wrap film on the core side, presses against the back side of the cutout part of the inner cover. By being locked, unwinding of the lamp film can be more completely prevented.

Further, when reusing the product, remove the protruding part of the outer cover from the cutout part of the inner cover, pinch the tip of the wrap film, pull out the required amount of wrap film, use it, and repeat the same operation thereafter.

(Example) Below, the specific content of the present invention will be explained based on the illustrated example. Figures 1 and 2 show a wrap film storage container made of a rectangular box. .

This storage container may be constructed using a cardboard carton blank as shown in FIG. 3, for example.

The carton blank of this example is based on the bottom plate 1,
On the - side, a rear panel 2 and an openable/closable outer panel 113 are connected via fold lines a and b, respectively, and on the other side, a front panel 7 is provided.
and an inner lid 8 are connected to each other via fold lines d and f, respectively.

Auxiliary pieces 12 are attached to the left and right ends of the bottom plate 1 via folded NIAe.
However, an end plate 13 and an insertion tongue piece 14 are connected to the left and right ends of the rear plate 2 via fold lines C and h.

Furthermore, in order to form a protrusion 4 in the outer cover 3, the protrusion 4 is formed longitudinally through the approximately central portion thereof, and the intermediate portion is directed in the opposite direction to the rear plate 2.
A curved perforation line 5 is applied, and the end opposite to the rear plate 2 with this perforation line as a border is an adhesive piece 6, and an outer cover 3 is attached.
Adhesive pieces 15 are connected to the left and right ends of the housing via ξ thin wires 16 .

On the other hand, a saw blade 9 is fixed to the inner cover 8 along the fold line f with the cutting edge slightly protruding toward the front plate 7 from the fold line f, and this blade 9 is attached near the bottom of the cutout portion 11a, which will be described later. It also plays the role of reinforcing the In addition, the inner lid 8
A sewing machine 's10 is used to form an approximately U-shaped cutout 11, which is slightly smaller in scale than the protrusion 4 of the outer lid 3, approximately at the center thereof.

Since this cutout part 11 is glued to the back surface of the protrusion part 4 of the outer M3 during assembly, it is cut off from the inner cover 8 together with the back surface of the protrusion part 4 at the same time as the outer cover 3 is first opened. The space becomes the resection trace portion 11a. Note that the cutout portion 11 serves as a reinforcing member for the protrusion 4 while remaining attached to the back side of the protrusion 4 .

Reference numeral 17 denotes adhesive pieces connected to both left and right ends of the inner lid 8 via fold lines g.

The above-mentioned carton blank is erected with the rear plate 2 and the front plate 7 along the fold lines a and d based on the bottom part 1, and the inner cover 18 and the outer cover 3 are aligned in mutually opposing directions along the fold lines f and b. 8 facing down, and after loading a roll of wrap film inside from the opening on the side, add an auxiliary piece 12 along the - fold line e, an adhesive piece 17 along the fold line g, and an adhesive piece 15 along the ξ thin line 16. , in the order of the end face plate 13 along the fold line C, overlap the openings on both the left and right end faces in the direction of closing, and finally insert the tongue piece 14 along the fold line into the inside of both the left and right ends of the front plate. , the adhesive pieces 6 of the outer cover 3 are adhered to intermittent points on the upper surface of the inner cover 8 via the adhesive 18, and the back surface of the protruding part 4 and the surface of the cut-out part 11 of the outer cover 3 are also adhered in the same manner to complete the container. is completed.

Therefore, when in use, pinch one end of the adhesive piece 6 and peel it off from the inner lid 8 before use! When the adhesive piece 6 is cut and removed from the outer lid 3 along the line 5 and the outer IE 3 is opened upward, the perforations 16 on both sides are cut out and the outer lid 3 becomes free to open and close. After that, find the end of the loaded lamp film, pull it out along the top surface of the inner lid 8, and when it reaches the required length, press the protrusion 4, or pull only the protrusion 4 from above the inner lid 8. Push the film along with the wrap film into the inside of the inner cover from the cutout portion 11a of the inner cover 8, and while pressing it against the surface of the rolled film, pull the pulled out wrap film in the direction along the front plate 7 and cut it with the saw blade 9. do.

(Effects of the Invention) As described above, the present invention involves pulling out the wrap film wound into a roll housed in a rectangular box body from the upper opening, and attaching it to the front plate side while pressing it with the outer lid. In a wrap film storage container that is used by cutting with a saw blade-like part, the upper opening is cut with a saw blade to cover approximately half of the opening from the front plate side and to make the cutting edge slightly protrude from the front plate. The blade is attached to the inner cover, and the central part is notched in a substantially U-shape in the direction of the saw blade to form a resection mark, and the center part of the tip of the outer cover is made to protrude to form a protruding part. Since the protruding part is locked inside the cutout part of the inner lid when the lid is closed, the roll core does not come out at all even when the wrap film is suddenly pulled out, and moreover, the wrap after use is fixed. The tip of the film is cut out by the protrusion 4 at the inner M8 cutout 11
As a result, there is no risk of the wrap film unwinding, and there is no need to expose the tip of the wrap film, so there is no waste, and it is hygienic and easy to handle. It has various beneficial effects.
