Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a packaging container for packaging a packaged body wound in a roll shape, for example, a resin film typified by a wrap film, paper, aluminum foil, and the like.
[0002]
[Prior art]
Conventionally, containers for wrapping various types of wrap film are known, but most of them are made of cardboard, and a container main body for storing a roll-wrapped wrap film and an integral body of the container main body. It is comprised from the cover body provided in. Moreover, generally the cutter for cut | disconnecting the wrap film pulled out from the container is attached to the back surface of the front wall of a cover body.
[0003]
When this type of container is used, the lid is lifted to expose the tip of the wrap film. And after picking and pulling the film front-end | tip part with a finger | toe, a cover body is closed and the drawn wrap film is cut | disconnected with a cutter.
[0004]
After the wrap film is cut, the tip of the wrap film remaining in the container is disposed between the front wall of the lid and the front wall of the container body, but the front wall surface of the container body is a smooth surface. Therefore, the entire film tip may be in close contact with the front wall of the container body.
[0005]
Thus, when the film front-end | tip part contact | adhered to the front wall of the container main body, it becomes difficult to pick a film front-end | tip part with a finger | toe. In particular, it is difficult for even the elderly and blind people to find the position of the film tip. Therefore, there is a problem that it takes time to draw out the wrap film.
[0006]
In order to deal with such problems, conventionally, as described in Japanese Utility Model Laid-Open No. 6-51128, Japanese Patent Application Laid-Open No. 11-59690, etc., a cut line is made on the front wall of the container body and protrudes outward. The thing which formed the protruding piece which does is proposed. The container 1 shown in FIG. 5 is an example, and it is possible to prevent the entire front end portion of the wrap film 5 from coming into close contact with the front wall 3 due to the presence of the protruding piece 4 of the front wall 3 of the container body 2. Yes.
[0007]
[Problems to be solved by the invention]
However, the protruding piece 4 formed on the front wall 3 of the container body 2 tries to return to a flat state due to the property of cardboard (generally coated cardboard) which is a material of the container 1, and is shown in FIG. Thus, it is necessary to maintain the protruding state using the rubber 6 (see Japanese Utility Model Laid-Open No. 6-51128). Attaching the rubber 6 in the manufacturing process of the container 1 takes time and increases the manufacturing cost, and it is not preferable to require the user to attach the rubber.
[0008]
This invention is made | formed in view of this situation, The objective is to provide the means for maintaining the protrusion state of the protrusion piece formed in the front wall of a container main body.
[0009]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention comprises a container main body that accommodates a packaged body such as a wrap film wound in a roll shape, and is rotatably provided from the top edge of the rear wall of the container main body. Forming a cut line that defines a protruding piece portion that becomes a protruding piece protruding outward on the front wall of the container body, and on the back surface of the protruding piece portion, A detent extending from the periphery of the protruding piece portion is provided.
[0010]
In such a configuration, when the protruding piece portion is pulled out to the outside of the container and used as a protruding piece for preventing adhesion of the entire front end portion of the wrap film or the like, the detent extends from the peripheral edge of the protruding piece. Even if the piece attempts to return inward, the detent can contact the surface of the front wall of the container body and prevent further movement.
[0011]
In addition, the front wall of the container body has a rectangular first wall body in which one long edge is connected to the bottom wall of the container body, and a second wall body that is connected to the other long edge of the first wall body. In the case where the second wall body is bent and bonded to the back surface of the first wall body, the protruding piece portion is defined by the first wall body, and the detent is covered by the protruding piece portion. It is preferable to be defined by a cut line formed in the portion of the second wall body. In this case, it is not necessary to attach the detent separately to the protruding piece, and it is only necessary to provide a cut line for the detent or protruding piece at the stage of making the container pattern.
[0012]
Further, the protruding piece portion may be provided in any part of the front wall of the container body, but it is preferable that the protruding piece part be defined in a part covered by the front wall of the lid in the closed state. This is because, when the cutter is attached to the lid side, even if there is a protruding piece at another part, the tip portion remaining immediately after cutting the packaged body such as a wrap film cannot be lifted.
[0013]
Furthermore, it is preferable that the protruding piece portion is defined in the longitudinal center portion of the front wall of the container body. If the projecting piece is provided, the package body is gripped there. Therefore, if the projecting piece is in the central portion, the position where the package body is gripped is also the center portion in the width direction of the package body, and one side This is because it is possible to suppress the occurrence of wrinkles.
[0014]
Furthermore, the present invention is particularly effective when a cutter for cutting an object to be packaged is provided at the front edge of the front wall of the lid. In such a container, the projecting piece is pressed by the front wall of the container body to return to the original position, but this can be prevented by the detent of the present invention.
[0015]

The container 10 is sealed by the opening piece, and the blade of the cutter 24 is prevented from being exposed. In use, the opening piece is removed.
[0020]
Here, the main body front wall 26 will be described in more detail with reference to FIG. The main body front wall 26 includes a rectangular first wall body 26 a having one long edge connected to the bottom wall 28 of the container body 16, and a trapezoidal first wall body 26 a connected to the first wall body 26 a by a folding line 27. The first wall body 26a is bent at a right angle with respect to the bottom wall 28, and the second wall body 26b is bent 180 degrees along the fold line 27 to form an adhesive on the back surface of the first wall body 26b. It is comprised by making it adhere | attach. In addition, the part of the code | symbol 26c is a part adhere | attached on the side wall 30 of the container main body 16. FIG. In the illustrated embodiment, the width W1 of the second wall body 26b is about one half to one half of the width W2 of the first wall body 26a.
[0021]
A substantially U-shaped cut line 32 is provided at a central portion in the longitudinal direction of the first wall 26a constituting the main body front wall 26 and covered with the lid front wall 22 in the closed state. . More specifically, the cut line 32 includes first and second cut lines 32a and 32b that extend in the vertical direction and are spaced apart from each other, and lower ends (fold lines) of the cut lines 32a and 32b. And a third cut line 32c extending in the lateral direction so as to connect each other. In the illustrated embodiment, the center portion of the third cut line 32c is curved toward the fold line 27 side. By projecting a portion (projecting piece portion) 34 ′ surrounded by the cut line 32 to the outside, a projecting piece 34 projecting outward from another region of the main body front wall 26 is formed.
[0022]
In addition, two cut lines 36a and 36b are provided in a central portion of the second wall body 26b constituting the main body front wall 26 and on the back side of the protruding piece portion 34 '. Referring also to FIG. 4, these cut lines 36 a and 36 b extend from the lower edge (free edge) of the second wall body 26 b toward the top edge (fold line) 27 of the main body front wall 26, and the top edge The closer to 27, the narrower the gap between them. Further, the interval between the lower ends of the cut lines 36a and 36b is slightly larger than the distance between the first and second cut lines 32a and 32b, and between the cut lines 36a and 36b at other positions. The cut lines 36a and 36b are formed so that the distance is smaller than the distance between the first and second cut lines 32a and 32b. Further, the top edge of the main body front wall 26 is extended from the upper ends of the cut lines 36a, 36b so that the portion 38 defined between the cut lines 36a, 36b does not restrain the movement when the protruding piece portion 34 'is pulled out. The distance D1 to 27 is made smaller than the distance D2 from the upper ends of the first and second cut lines 32a and 32b to the top edge 27.
[0023]
In addition, it is suitable for the surface of the main body front wall 26 to be provided with an adhesive layer for preventing the wrap film 14 from rewinding. The pressure-sensitive adhesive layer is formed in a portion covered by the lid front wall 22 in the closed state so that the film leading end can be detachably held immediately after the wrap film 14 is cut. In the container 10 of the illustrated embodiment, the adhesive layer is preferably provided on the central portion of the main body front wall 26, and thus on the surface of the protruding piece 34, in order to cut the wrap film 14 while pressing the central portion of the lid front wall 22. .
[0024]
In such a configuration, when the user uses the sealed container 10, first, an opening piece (not shown) is removed from the lid front wall 22, the lid 18 is opened, and the back of the main body front wall 26 is placed. A finger is inserted, and the protruding piece portion 34 'surrounded by the cut line 32 of the first wall 26a is pushed outward. Thereby, the protruding piece 34 shown in FIG. 1 is formed. At this time, the portion 38 between the cut lines 32a and 32b of the second wall body 26b bonded to the first wall body 26a is also pushed outward. As can be seen from FIG. 4, the lower corner portion 40 of the portion 38 extends laterally from the peripheral edge (ie, the cut line 32) of the protruding piece portion 34 ′. In a state in which the protruding piece portion 34 ′ is drawn out as the protruding piece 34 to the outside of the container 10, the lower corner portion 40 of the portion 38 faces the portion adjacent to the protruding piece 34 on the surface of the main body front wall 26. Become. Therefore, even when trying to return to the flat original state due to the characteristics of the coated cardboard, the lower corner portion 40 abuts on the front wall 26 of the main body and functions as a detent so that the protruding state of the protruding piece 34 is maintained. become.
[0025]
When the protruding piece 34 is in a state of protruding outward, immediately after the wrap film 14 is cut by the cutter 24, a part of the tip of the wrap film 14 is lifted from the other region of the main body front wall 26 by the protruding piece 34. Thus, the user can easily grip the wrap film 14. The third cut line 32c is curved and an upward concave portion 42 is formed at the lower edge of the protruding piece 34. The presence of the concave portion 42 makes it easier to insert a finger below the protruding piece 34. This makes it easier to hold the wrap film 14.
[0026]
At this time, since the projecting piece 34 is arranged at the center portion in the longitudinal direction of the main body front wall 26, the center portion in the width direction of the wrap film 14 is picked. This makes it difficult for the negative effects to occur.
[0027]
When the leading end of the wrap film 14 is gripped, the desired length is pulled out, and the lid 18 is closed tightly as shown in FIG. The center portion is pressed, the container 10 is twisted forward, and the wrap film 14 is cut by the cutter 24. At this time, a force toward the inside of the container acts on the protruding piece 34 via the lid front wall 22, but the protruding piece 34 is kept in the protruding state due to the presence of the detent 40.
[0028]
If such a protruding piece 34 is unnecessary, it is not necessary to push out the portion 34 ′, and if it becomes unnecessary after the protruding piece 34 is pulled out, it can be pushed back inside the container 10. Good. Once the protruding piece 34 is in the initial state, the detent 40 is in contact with the back surface of the first wall 26a, thus preventing outward protrusion.
[0029]
As mentioned above, although preferred embodiment of this invention was described in detail, it cannot be overemphasized that this invention is not limited to the said embodiment.
[0030]
For example, in the above embodiment, the cutter is attached to the front wall of the lid, but the present invention can be applied to a container in which the cutter is attached to the bottom wall of the container body. In such a case, the protruding piece does not need to be disposed at a position covered with the lid front wall 22.
[0031]
Further, the protruding piece is not limited to one place, and may be provided at a plurality of places.
[0032]
Furthermore, in the said embodiment, the cut piece is put into the 1st wall body and 2nd wall body which comprise a main body front wall, and it is made to form a protrusion piece and a detent. The formation of the cut line can be incorporated in the stage of manufacturing the paper pattern of the container, and does not increase the manufacturing cost, but is a simple method. However, a paper piece that serves as a detent is bonded separately to the back surface of the protruding piece. Is also possible.
[0033]
Further, the detent may be extended not only from the left and right sides of the projecting piece but also from the lower edge.
[0034]
Furthermore, the body to be packaged by the container according to the present invention may be not only a wrap film but also other resin films, paper, aluminum foil, and the like.
[0035]
【The invention's effect】
As described above, according to the present invention, since a part of the front end portion of the packaged body such as a wrap film is lifted from the front wall of the main body due to the presence of the protruding piece, the front end portion can be easily grasped. It can be pulled out. In particular, it is effective for situations where it is difficult to find the position of the edge of the packaged body or for the visually impaired. In addition, since the protruding piece is maintained in the protruding state by the detent, the adverse effect that the surface of the protruding piece and the surface of the other region of the front wall of the main body are flush with each other can be prevented, Easy to grip.
[0036]
In addition, when the cutter is attached to the front wall of the lid, there is an operation of pressing the front wall of the lid against the front wall of the main body together with the packaged body, so that the protruding piece tends to return to the original flat state. Since this invention has the said protrusion maintenance effect with respect to the packaging container of a type, it becomes especially effective.
