  In general, the resin wrap film as described above is used not only for wrapping food and storing in a refrigerator, but also for heating or thawing in a microwave oven when eating food. For this reason, the carton containing the wrap film may be placed on the microwave oven. In such a case, the top surface of the device becomes hot during operation of the microwave oven, so that heat is transmitted through the carton, and the surfaces of the plastic wrap films soften and stick to each other, pulling the ends. However, it causes a problem that the carton cannot be drawn out smoothly.

  The present invention has been made in view of such problems, and the purpose of the present invention is to prevent the wrap film inside from sticking even when used on a microwave oven. An object of the present invention is to provide a carton for a wrap film that can be smoothly fed out.

  In order to achieve the above object, the wrap film carton according to the present invention accommodates a resin wrap film wound in a roll on a paper tube consisting of a main body front plate, a main body bottom plate, a main body rear plate and a main body side. A carton main body, a lid upper plate continuously provided at the upper edge of the rear plate of the main body, a lid front plate continuously provided at the tip of the lid upper plate and overlapping an upper portion of the main body front plate, and a lid From the lid side that connects both ends of the upper plate and the lid front plate, an opening plate that is connected to the tip of the lid front plate via a break line and is glued to the lower part of the main body front plate, and the lid front plate In a carton for a wrap film having a saw blade member mounted on the back side near the front end of the lid front plate in a state where the blade edge portion protrudes, two side wall inner plates and a main body which are connected to the main body front plate and the main body rear plate, respectively. The side of the main body is composed of the side wall outer plate that is connected to the bottom plate. In addition, a leg piece is provided so as to sandwich the side wall outer plate on one side wall inner plate, and a slit is formed at a position corresponding to the leg piece at the boundary between the main body bottom plate and the side wall outer plate, and the two pieces are bent. When the side wall outer plate is folded and stacked from above the side wall inner plate, the leg piece passes through the slit and protrudes from the boundary between the main body bottom plate and the side wall outer plate to the lower part of the carton main body.

  The carton for wrap film of the present invention has a shape in which the leg pieces protrude downward from both ends of the main body bottom plate. However, the carton body is tilted by the leg pieces, and the bottom plate of the main body is separated from the grounding surface and a gap for heat insulation is formed, so even if the equipment gets hot while it is placed on the microwave oven, Heat is prevented from being transmitted to the film, and it is softened and does not stick to each other, so that it can always be smoothly fed out from the carton.

  And since it does not make a big change to the conventional carton form, it can be assembled using existing equipment, so despite adding a new function to prevent heat conduction from the bottom, Less equipment and development costs.

It is explanatory drawing which shows the assembly procedure following FIG. It is explanatory drawing which shows the assembly procedure following FIG. It is explanatory drawing which shows the assembly procedure following FIG. It is a perspective view shown in the state which opened the carton for wrap films of FIG.

  Next, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a perspective view showing an example of a wrap film carton according to the present invention, and this wrap film carton C is formed by assembling a blank shown in FIG. This blank is obtained by punching a paperboard used for an ordinary paper container. In the figure, the upper side and the lower side of the line AA are constituent parts of the carton body 1 and the lid body 2, respectively.

  The carton body 1 includes a horizontally long main body front plate 11, a main body bottom plate 12, and a main body rear plate 13 successively connected via a fold line. Larger side wall inner plates 14 are arranged on both sides of the main body rear plate 13. However, a side wall outer plate 15 is connected to both sides of the main body bottom plate 12 and a smaller side wall inner plate 16 is connected to both sides of the main body front plate 11 via folding lines. Further, an insertion flap 17 is continuously provided on the outer side of the side wall outer plate 15 via a fold line having cuts on both sides, and the protruding portion 15a protruding outward by bending the insertion flap 17 is formed on the side wall outer plate. It is divided by a cut in the middle of 15.

  As for the constituent parts of the lid body 2, a lid body upper plate 21 is connected to the body rear plate 13 of the carton body 1 via a fold line, and a lid body front plate 22 is further connected to the lid body top plate 21 via a fold line. An opening plate 23 is continuously connected to the lid body front plate 22 via a breaking line α in which T-shaped cuts are continuous, and lid body side plates 24 are provided on both sides of the lid body upper plate 21. Adhesive pieces 25 are connected to both sides of the lid front plate 22 via fold lines. The total width of the lid front plate 22 and the unsealing plate 23 is set to be the width of the main body front plate 11 of the carton main body 1.

  The lid front plate 22 overlaps with the upper portion of the main body front plate 11 of the carton main body 1, and the unsealing plate 23 is pasted to the lower portion of the main body front plate 11 of the carton main body 1. Then, in order to glue the unsealing plate 23 to the main body front plate 11 in a state of being easily peeled off, a plurality of adhesion points 11a are formed by circular half-cut lines in the vicinity of the main body bottom plate 12 in the main body front plate 11, and correspondingly Then, an adhesion point 23 a is formed in the opening plate 23 by a semicircular cut.

  Further, a saw blade member 3 for cutting the wrap film is attached to the back side near the front end of the lid front plate 22 with an adhesive or the like in a state where the blade edge portion protrudes from the lid front plate 22 to the opening plate 23 side. At the start of use, the cutting plate 23 glued to the lower part of the main body front plate 11 of the carton main body 1 is separated from the cover front plate 22 along the breaking line α while being peeled off from the main body front plate 11, and the cutting edge of the saw blade member 3 The portion is exposed from the lid front plate 22 (see FIG. 7).

  The blank is devised so that leg pieces protrude from both ends of the main body bottom plate 15 when assembled as a carton C. Specifically, a triangular leg piece 16 f is projected from the smaller side wall inner plate 16 so as to sandwich the side wall outer plate 15, and at the boundary between the main body bottom plate 12 and the side wall outer plate 15, A slit β is formed at the corresponding position. Here, when the side wall outer plate 15 is folded and overlapped from above the bent side wall inner plate 16, the leg piece 16f can easily pass through the slit β. A triangular rocking piece 15f as shown in the figure is formed by the incision included. A triangular hole may be formed instead of leaving such a swinging piece 15f, but if the swinging piece is used, dust does not come out when blanking.

  The oval cut region 15b formed in the side wall outer plate 15 is a means for preventing the paper tube wrapped with the wrap film from being formed with a cut line having a jumper on the way. When the cut region 15b is pushed in, the hollow portion is entered from the end of the paper tube. In order to allow the cut region 15b to be pushed in, as shown in the figure, a notch portion 16a for passage is provided in the side wall inner plate 16, and the side wall inner plate 14 as a whole is roughly Y-shaped. A push-in flap portion 14a is provided that is formed of three foldable flaps that are substantially triangular in shape with a cut line.

  The blank of FIG. 2 which consists of said structure is assembled, and the carton C for wrap films shown in FIG. 1 is created. Specifically, first, a blank is sack pasted so that the adhesion point 11a of the main body front plate 11 and the adhesion point 23a of the opening plate 23 are bonded together. And, in the filling process, after raising the blank in the sack pasted state into a rectangular tube shape, after closing one open portion, the wrap film wound in a roll shape on the paper tube is charged from the other side portion, Thereafter, the other opening is also closed.

  The assembly procedure for closing one open part and the other open part is as follows. Referring to the right side of FIG. 1, the side wall inner plate 14 and the side wall inner plate 16 are first bent in this order from the open state shown in FIG. 3 as shown in FIGS. As a result, as shown in FIG. 5, the leg pieces 16f of the side wall inner plate 16 overlap the swinging pieces 15f of the side wall outer plate 15.

  Next, after applying the paste so as to straddle both the folded side wall inner plate 14 and the side wall inner plate 16, the side wall outer plate 15 is folded so as to be overlaid thereon, and the insertion flap 17 at the tip is attached to the lid. Insert under the top plate 21 and cover as shown in FIG. At this time, the leg piece 16f of the side wall inner plate 16 passes through the slit β so as to push away the swing piece 15f of the side wall outer plate 15, and protrudes from the boundary between the main body bottom plate 12 and the side wall outer plate 15 to the lower part of the carton main body 1. To do. Further, the cutout portion 16a of the side wall inner plate 16 avoids the pushing flap portion 14a of the side wall inner plate 14, and the cut region 15b of the side wall outer plate 15 is overlapped with the pushing flap portion 14a.

  Subsequently, the adhesive piece 25 is bent and glue is applied thereon, and then the lid side plate 24 is bent and bonded thereto. Thus, by closing both open parts, the main body side part connecting both ends of the main body front plate 11, the main body bottom plate 13 and the main body rear plate 13 is formed, and both ends of the lid upper plate 21 and the lid front plate 22 are connected. A lid side portion to be connected is formed.

  The assembly process including the sack pasting process and the filling process is the same as a conventional carton without a leg piece. Therefore, the wrap film carton C shown in FIG. 1 can be assembled by using an existing apparatus as it is.

  The wrap film carton C shown in FIG. 1 has a shape in which leg pieces 16 f protrude downward from both ends of the main body bottom plate 12. For this reason, when placed on a flat place, the main body bottom plate 12 is separated from the grounding surface and a gap is formed, and even if the device is heated on the microwave oven, Heat is prevented from being transmitted, and it does not soften and stick to each other.

  The wrap film carton C is opened when in use, while the lower end of the front plate 11 of the carton main body 1 is gripped at the end of the opening plate 23 glued by the adhesion points 11a and 23a and peeled off from the main body front plate 11. It is opened by separating from the lid front plate 22 at the breaking line α and exposing the blade edge portion of the saw blade member 3 from the lid front plate 22. And the notch area | region 15b formed in the side wall outer plate 15 of both ends is each pushed in, and the removal prevention means of the paper cylinder which wound the wrap film is formed. After that, as shown in FIG. 7, the wrap film is drawn out by a desired length with the lid 2 opened, and then the carton body 1 is covered with the lid 2, and the drawn wrap film is attached by the saw blade member 3. cut out.

  Even if the carton C for wrap film is opened, the leg pieces 16f are protruded downward from both ends of the main body bottom plate 12. Accordingly, when the wrap film carton C is opened and placed on a flat surface with the main body bottom plate 12 facing down, the leg pieces 16f incline the carton main body 1 and separate the main body bottom plate 12 from the grounding surface to provide a gap. In other words, even if the device gets hot when placed on the microwave oven, heat is prevented from being transmitted to the wrap film, and it will not soften and stick to each other, so it can always be drawn out smoothly from the carton. .

  At the time of assembling the wrap film carton C, the side wall outer plate 15 is overlapped and attached to the side wall inner plate 14 and the side wall inner plate 16, and the insertion flap 17 is bent inward with respect to the side wall outer plate 15 at this time. The protrusion 15a partitioned by the side wall outer plate 15 rises elastically due to the repulsive force of the paper. Further, in a state where the adhesive piece 25 is bonded to the lid side plate 24, the upper side of the adhesive piece 25 forms a step on the inner surface of the lid side plate 24, so that when the lid 2 is put on the carton body 1, the projection The portion 15a is caught on the stepped portion, and the lid 2 is prevented from being lifted from the carton body 1.

  As mentioned above, although embodiment of this invention was described in detail, the carton for wrap films by this invention is not limited to the said embodiment at all, In the range which does not deviate from the meaning of this invention, it is various changes. It is natural that this is possible.

  For example, in the above example, the leg piece 16f protrudes from the smaller side wall inner plate 16 with the side wall outer plate 15 interposed therebetween. However, the leg piece protrudes from at least one of the side wall inner plates. And a slit may be formed at a position corresponding to the leg piece at the boundary between the main body bottom plate and the side wall outer plate.
