[Problem that the idea aims to solve] In the wrap film storage case shown in Fig. 8, the wrap film W is cut. When the cover plate 2 or the cover piece 3 is pressed in the direction of the case body 1 with your finger, as shown in Fig. 9. As shown by the solid line, the cover plate 2 covers the opening 1f, and the cover piece 3 covers the front plate 1d. The front is covered, and the wrap film W is sandwiched between the front side plate 1d and the cover piece 3, Cut by the cutting member 4. However, after this cutting process, when I let go of the case, the , due to the elasticity of the cardboard of the hinge part 2a, the hinge part The cover plate 2 is naturally lifted upward from the opening 1f, and the cover plate 2 is separated from the opening 1f. At the same time, the cover piece 3 also separates from the front plate 1d. In this way, the cover piece 3 opens forward. As a result, it is pulled out from the film roll 5 and placed in front of the front plate 1d by the adhesive material 6. The film that is held in place will be exposed. This type of wrap film W is used to wrap food, so when it is stored, It is not sanitary to leave it exposed in front of the front side plate 1d. In addition, cover plate 2 is also The case separates from the opening 1f of the main body 1, and the opening 1f is incompletely closed. The film roll 5 stored in the base body 1 is also exposed to the outside air, which is preferable for hygiene. You will be left in an uncomfortable situation.

An adhesive piece 18b is bent from the cover plate 17 and extends to the side edge of the cover piece 18. It is bent and adhered to the inner surface of the side cover piece 19.

0010 Next, a method of using the wrap film storage case will be explained. The wrap film W pulled out from the film roll 5 inside the case body 10 is It is guided to the outside through the opening 15 of the base body 10 through between the front side plate 12 and the cover piece 18. It will be done. When the desired length of wrap film W is pulled out, this wrap film Spread the W on an object to be packaged, such as a tray, in a nearly horizontal state. Then use one hand to hold the lid plate. 17 or the cover piece 18, and as shown in FIG. 3(A), the cover plate 17 15 so that the cover piece 18 overlaps the front of the front side plate 12. other hand Pull the wrap film W horizontally and lower the case in the α direction (see Figure 3 (A)). Twist. As a result, the saw blade of the cutting member 20 arranged in a V-shape causes the lap filler to be removed. The central part of the arm W is cut, creating a trigger for cutting. Just wrap film When W is pulled horizontally, the lap fift will form an almost V-shape along the saw blades lined up in a V-shape. lume W is cut. Of the wrap film W that was cut and remained on the case body side , the portion sandwiched between the front side plate 12 and the cover piece 18 is such that the cover piece 18 cannot be pressed with your fingers. As a result, the film is stuck and held by the adhesive part 21a of the film holding section 21 shown in FIG. Therefore, rewinding to the film roll 5 can be prevented.

[0011] Here, as shown in FIG. 3(A), the cover plate 17 and the cover piece 18 are connected to the case body. 10, when the cover piece 1 is closed, the protrusion 14a protruding forward from the end plate 14 Press against the inner surface of 8. As mentioned above, the cover piece 18 and the cover plate 17 are connected to each other by the side cover piece 19. Since the cover pieces 18 are connected to each other, the cover pieces 18 cannot be opened independently to the front of the front side plate 12. Rather, the protrusion 14a is located on the inner surface of the cover piece 18 due to the rigidity of the cardboard material. Press firmly. Therefore, the film cutting work is completed and the wrap film storage case is Even if you take your hand off the base, the cover plate 17 and the cover piece 18 are held together by the elasticity of the hinge part 16. The device will not be separated from the main body 10, and will remain in the closed state shown in FIG. 3(A) even during storage. The condition is maintained.

0012 Therefore, it is located between the front side plate 12 and the cover piece 18 and is held by the film holding part 21. The wrapped film is not exposed to the outside. Also, the cover plate 17 opens the Since the mouth portion 15 is maintained in a closed state, dust does not accumulate inside the case body 10. Nothing can get in there. Furthermore, as shown in FIG. 3(A), the cover piece 18 is a front plate. 12 is maintained in a stacked state in front of the front plate 12, the space between the front side plate 12 and the cover piece 18 The part of the wrap film that is not crimped by the film holding section 21 never rolls up. Furthermore, the wrap film is separated from the film holding section 21. Even if the wrap film W is caught between the front side plate 12 and the cover piece 18, Since the film is held in place, winding back onto the film roll 5 is less likely to occur. Further, when the wrap film W is further pulled out and cut after that, the lid plate 17 is Although it is necessary to separate the cover piece 18 from the case body 10, the protrusion 14a and the cover piece 1 The pressure contact force between the cover plate 17 and the cover plate 8 is sufficient to appropriately hold the cover plate 18. Excessive force is not required when opening the pieces 18 and they can be opened easily.

[0013] In the above embodiment, as shown in FIG. 3(B), the protrusion 14a formed on the end plate 14 is The upper part thereof forms an inclined part 14b that gradually projects forward. Therefore, the lid plate 17 and the cover When the cover piece 18 is closed to the case body 10, the inner surface of the cover piece 18 hits the inclined part 14b. As it closes, it is brought into pressure contact with the tip of the protrusion 14a. However, the shape of the protrusion 14a formed on the end plate 14 is as shown in FIGS. 1 to 3(B). The shape is not limited to the shape shown in each figure, for example, the semicircular shape shown in FIG. 4(A), the semicircular shape shown in FIG. ) may be approximately triangular in shape. Furthermore, as shown in FIG. 4(C), the end plate 14 A plurality of protrusions 14a and 14c may protrude from.

[0014] Next, FIG. 5 shows a part of the wrap film storage case according to the second embodiment of the present invention. An enlarged partial perspective view, FIG. 6(A) shows a state in which the cover plate, cover piece, and side cover piece are closed. Figure 6 (B) is a partial front view showing the storage case for wrap film. It is a partial front view which shows the front side plate and protrusion before a side lid piece is closed. Although Figure 5 shows only a part of the wrap film storage case, the wrap film The overall structure of the room storage case is similar to that shown in Figure 1, with a bottom plate 11, a front plate 12, a case body 10 having a back plate 13 and both end plates 14, and this case body A lid plate 17 continuous to the back plate 13 of No. 10, a cover piece 18 continuous to the lid plate 17, It has a cover plate 17 and side end plates 19 that connect both ends of the cover piece 18 to each other. Further, a cutting member 20 is provided at the leading edge of the cover piece 18, and a cutting member 20 is provided on the front edge of the front side plate 12. is provided with the same film holding section 21 as shown in FIG. 1 (not shown in FIG. 5). ing.

[0015] In this second embodiment, projections 12c are provided at both left and right ends of the front side plate 12, respectively. It is integrally formed to protrude outward. Figure 5 shows only one of the protrusions 12c. It shows. As shown in FIGS. 5 and 6(B), the protrusion 12c is located on the surface of the end plate 14. It stands out from the surface. The shape of the protrusion 12c is approximately trapezoidal, and both the upper and lower front edges of the protrusion 12c are trapezoidal. The corner portion 12d has an R shape (arc shape). FIG. 6(B) shows the cover plate 17 and cover piece 18. This shows that the side cover piece 19 is not closed. The protrusion dimension B in which the protrusion 12c protrudes laterally from the end plate 14 is as shown in FIG. 6(A). , the end plate 14 and the side lid in a state where the lid plate 17, the cover piece 18, and the side lid piece 19 are closed. It is formed to be larger than the gap dimension b between the inner surface of the piece 19 and the inner surface of the piece 19. Note that, similarly to the embodiment shown in FIG. 2, the end plate 14 is bent from the bottom plate 11. It is something. At the side end portion of the front side plate 12, there is a portion where the projection 12c is not formed. The adhesive piece 12b is extended and is bent and adhered to the inner surface of the end plate 14. It is. Further, the adhesive piece 13a continuous to the side edge of the back plate 13 is the same as the adhesive piece 12b. It is also glued on the inside. In addition, the upper edge of the front side plate 12 has a continuous bent piece 12a. This is folded and adhered to the inner surface of the front side plate 12. Sara The side cover piece 19 is bent from the cover plate 17, and the cover piece 18 is also folded from the cover plate 17. The adhesive piece 18b extending to the side end of the cover piece 18 is bent and the side edge is bent. It is adhered to the inner surface of the lid piece 19.

[0016] In this embodiment, as shown in FIG. 6(A), if the cover plate 17 and the cover piece 18 are When the side cover piece 19 is closed to the case body 10, from the side end of the front side plate 12. A protrusion 12c projecting outward from the end plate 14 comes into pressure contact with the inner surface of the side cover piece 19. mentioned above As shown, since the cover piece 18, cover plate 17, and side cover piece 19 are connected to each other, the protrusion The side cover piece 19 independently opens far away from the end plate 14 due to the pressure contact force with the end plate 12c. Rather, the protrusion 12c is located on the inner surface of the side cover piece 19 due to the rigidity of the cardboard material. Press firmly. Therefore, the film cutting work is completed and the wrap film storage case is Even if you take your hand off the base, the cover plate 17 and the cover piece 18 are held together by the elasticity of the hinge part 16. The device will not be separated from the main body 10, and will remain in the closed state shown in FIG. 6(A) even during storage. The condition is maintained.

[0017] Therefore, it is located between the front side plate 12 and the cover piece 18 and is held by the film holding part 21. The cut wrap film is not exposed to the outside. Also, the cover plate 17 Since the opening 15 is maintained in a closed state, there is no air inside the case body 10. There is no possibility of dust getting in. After that, pull out the wrap film W further and cut it. When cutting, separate the cover plate 17, cover piece 18, and side cover piece 19 from the case body 10. Although necessary, the pressing force between the protrusion 12c and the inner surface of the side cover piece 19 causes the side cover piece 19 to Since the cover plate 17, the cover piece 18, and the side cover piece 19 are held properly, Excessive force is not required when opening from the main body 10, and it can be opened easily. In addition, in the above embodiment, as shown in FIG. 6(B), the The protrusion 12c is formed at a position lower than the upper edge of the front plate 12 by the dimension H. However, the upper edge of the protrusion 12c is aligned with the upper edge of the front plate 12, so that the dimension H is reduced to zero. You can also do this. Furthermore, the shape of the protrusion 12c formed on the front side plate 12 is as shown in FIG. 5 to FIG. 6(B). For example, the shape is not limited to the shape shown in each figure, such as the semicircular shape shown in FIG. The substantially triangular shape shown in B) may also be used. Furthermore, as shown in Figure 7(C), the front plate A plurality of protrusions 12a and 12c may protrude from 12.

[0018]

[Effect of the idea]

As described above, according to the present invention, the lid plate, the cover piece, and the side lid piece are closed to the case body. When the protrusion on the end plate or the protrusion on the front plate is a cover piece or a side cover piece. The cover plate, the cover piece, and the side cover piece are held in a closed state by being pressed against them. Therefore, is it a case? When the hand is released, the hinge at the boundary between the back plate and the cover plate elastically returns, allowing the cover plate and cover to close together. It is possible to prevent the lid piece and side lid piece from opening naturally. Therefore, film cutting The film remaining between the front plate and the cover piece will not be exposed afterwards, and the case The body remains sealed. Therefore, the wrap film is kept in a sanitary condition. . Also, since the protrusion projects integrally from the end plate or front plate, for example, When making a storage case from cardboard, there may be some protrusions when cutting the end plate or front plate. This can be dealt with by leaving the shape intact. Therefore, the production of storage cases is the same as before. and is easy to manufacture.
