JP 2000-203567 A JP 2002-326627 A

  According to the wrapping film storage box described in Patent Documents 1 and 2 above, when using a wrap roll without a core (coreless wrap roll), the winding diameter of the wrap roll is small and light, and it is easy to bend. At the end of use, the pulling force when pulling out the wrap film out of the box and guiding it to the cutter is concentrated in the center of the length of the wrap roll, and this pulling force is applied to the wrap roll without the core. Therefore, there is a problem that when the wrap roll is bent and acts as a bending force, it is difficult to unwind and unwind the wrap film.

  The present invention has been devised in view of the above circumstances, and the problem is that when using a wrap roll without a core, the latter half of the wrap roll is easily bent even when it is easy to bend. An object of the present invention is to provide a wrapping film storage box that can be avoided and can be smoothly unwound and drawn out to the end.

  In order to solve the above-mentioned problems, the packaging box for packaging wrap film of the present invention includes a storage box main body that can store a wrap roll wound with a wrap film from an upper opening, and one side of the storage box main body. A lid that is connected to an edge and opens and closes the opening; a hanging piece that is connected to the front edge of the lid and overlaps the outer surface of the front wall of the storage box body when the lid closes the opening; and And a cutter for cutting a wrap film fed out of the box from the wrap roll, and a storage box for a wrap film, wherein the wrap roll is accommodated in the storage box body after being placed on the wrap roll. It has an inner lid to be placed, and the inner lid is provided with a slit through which a wrap film fed from the wrap roll is passed in the center of the width.

  According to the packaging wrap film storage box configured as described above, when the wrap film is used for the first time after the lid is opened, the wrap film fed out from the wrap roll is already peeled from the wrap roll over the entire width, and the slit of the inner lid Can be set to pass through. For this reason, the operation of drawing the wrap film out of the box from the beginning of use and guiding it to the cutter is easy, and the film can be drawn evenly over the entire width of the film. In addition, from the beginning to the end of use, the guide film functions to peel the wrap film fed from the wrap roll from the wrap roll evenly over the entire width. In particular, in the latter half of use, when the operation of drawing the wrap film out of the box and guiding it to the cutter is performed, the force concentrates on the center of the length of the wrap roll having a small winding diameter and light weight. This force acts as a bending force on the coreless wrap roll, but since the wrap film is passed through the slit of the inner lid, the force is distributed over the entire width of the wrap film, making the winding diameter small and lightweight. The resulting wrap roll does not act to bend and floats while the inner lid is placed, and at this time, it performs a guiding function to evenly remove the wrap film from the wrap roll over the entire width.

  In the wrapping film storage box having the above-described configuration, the inner lid has one end of the slit and an inner lid side end for passing the wrap film fed from the wrap roll from one side outside in the longitudinal direction into the slit. It is desirable to have a slot to tie. According to this configuration, the work can be easily performed in a short time by passing the wrap film fed from the wrap roll into the slit of the inner lid, which is suitable for mass productivity. In addition, even when the film is unexpectedly cut off during use and the film edge passes through the slit of the inner lid, the film edge is cut off from the inner lid by the slit on the inner lid. It is possible to quickly and easily restore the usable state through the slit.

  According to the wrapping film storage box of the present invention, by providing the inner lid having a slit through which the wrapping film is passed, when performing the operation of drawing the wrapping film out of the box and guiding it to the cutter, A uniform tension is applied to the entire width, and the wrap film is provided with a guide function that allows the wrap film to be fed out without causing wrinkles or unevenness. In addition, when using a wrap roll without a core, the wrap roll is easily bent. Even in the latter half of use, the pulling force when pulling out the wrap film out of the box and guiding it to the cutter is averaged over the entire width of the film, so that bending of the wrap roll without the core can be avoided. It has an excellent effect that it can be smoothly unwound to the end and delivered.

Hereinafter, a wrapping film storage box according to an embodiment of the present invention will be described with reference to the drawings.
[First Embodiment]
First, as shown in FIG.1 and FIG.2, the storage box 10 for wrap films has the storage box main-body part 11, the cover part 12, the drooping piece part 13, and the cutter 14, Furthermore, a storage box The main body 11 has an inner lid 15A with a slit for accommodating the wrap roll R and placing the wrap film F in a state where the wrap film F is passed through the slit 15a.

  The storage box main body 11, the lid 12 and the hanging piece 13 are formed by punching into a required developed shape using a paper material such as coated cardboard (550 g / m 2), for example, and the paperboard having the required developed shape is bent. And it is provided so that a horizontally long substantially prismatic sealed space may be formed using an adhesive if necessary. Similarly to the above, the inner lid 15A is formed by stamping using a paper material.

  The storage box main body 11 includes a bottom wall portion, a front wall portion, a rear wall portion, and left and right side wall portions, and is a portion that can store a wrap roll R around which a wrap film F is wound from an upper opening. The lid part 12 is connected to one side edge (upper edge of the bottom wall part) of the storage box body part 11 to open and close the opening. The hanging piece 13 is connected to the front edge of the lid 12 and overlaps the outer surface of the front wall 11a of the storage box body 11 when the lid 12 closes the opening. The left and right side wall portions are provided with restriction pieces 16 that enter into the opening of the end surface of the wrap roll R and restrict movement of the wrap roll R, such as lifting. The restricting piece 16 is a tongue-shaped portion surrounded by a perforated cut line and a fold line pressed so as to be thin, and the user presses the tongue-shaped portion with a finger to make the perforated cut line. It cut | disconnects and makes it penetrate into the end surface opening of the lap roll R.

  The cutter 14 is provided at an appropriate position and cuts the wrap film F fed out from the wrap roll R to the outside of the box. Here, the cutter 14 is formed by press-punching a metal thin plate, a plastic plate, or a paperboard, or is formed by plastic molding, and is provided at the front lower edge of the bottom wall portion of the storage box main body portion 11. ) Protruding forward.

  The inner lid 15A includes a slit 15a through which the wrap film F fed from the wrap roll R passes in the center of the width, and the wrap film F fed from the wrap roll R into the slit 15a from one side outside in the longitudinal direction. A slit 15b that connects one end of the slit 15a and the end on the inner lid side is provided.

  According to the packaging wrapping film storage box having the above configuration, when the wrapping film is used for the first time after the lid 12 is opened, the wrapping film F fed out from the wrapping roll R is already peeled from the wrapping roll R over the entire width. Since it can be set in a state where it passes through the slit 15a of the inner lid 15, it is easy to draw the wrap film F out of the box and lead it to the cutter 14 from the beginning of use, and it can be drawn evenly over the entire width of the film.

  When the manufacturer sets the wrap film F in a state where the wrap film F is passed through the slit 15a of the inner lid 15A, the inner lid 15 is separated from the storage box, so that the handling property is good, and further, the slit 15b is split at one end of the slit 15a Therefore, the wrap film F can be easily passed through the slit 15a. The wrap film storage box 10 is also applied to a case where a new wrap roll is exchanged when the wrap roll R is used up. In this case, the consumer can easily pass the wrap film F through the slit 15a.

  The inner lid 15A serves as a guide function for peeling the wrap film F fed from the wrap roll R from the wrap roll R evenly over the entire width from the beginning to the end of use. In particular, in the latter half of use, when the operation of drawing the wrap film F out of the box and guiding it to the cutter 14 is performed, the force concentrates at the center of the length of the wrap roll R having a small winding diameter and light weight. This force acts as a bending force for the wrap roll R without the core, but since the wrap film F is passed through the slit 15a of the inner lid 15, the wrap roll R having a small winding diameter and a light weight is obtained. The inner lid 15A floats without being bent, and at this time, the inner lid 15A performs a guide function of peeling the wrap film F from the wrap roll R evenly over the entire width.
