Description

  The present invention relates to an improvement of a container that accommodates a packaging film roll used for packaging foods and various articles, and in particular, facilitates an operation of drawing and cutting one end of a film unwound from a film roll to a required length outside the container. It is related with the container for packaging film rolls which can be made.

The packaging film roll is sold in a state of being housed in a rectangular parallelepiped box, and when used, after pulling one end of the film roll from the open part provided on one side of the box by the required length, the box Cut with a cutter on the body. When pulling out one end of the film roll, the dimensions of the box, the material of the inner wall, etc. are devised so that the film roll main body can be rotated in the box (for example, JP 05-229553 A).
However, the film roll is accommodated in a state of being seated on the inner bottom surface of the box, and in a state where the film winding thickness with respect to the outer peripheral surface of the core is sufficiently thick, it is difficult to rotate in the box, so it cannot be pulled out well. If it is forcibly pulled out, wrinkles and skews may occur, cutting defects may occur, and there is a waste that the part has to be discarded. In addition, when the remaining amount of the film roll is reduced, it is excessively rotated in the box and sent out excessively, or on the contrary, the desired length cannot be drawn by rewinding, or the film leading edge is adsorbed to the film roll body, etc. Drawer failure was easy to occur.
In order to solve such problems, Japanese Patent Application Laid-Open No. 2002-326628 provides a return prevention member, but the size of the box is increased to accommodate the return prevention member. There was a drawback that overfeed could not be prevented.
In addition, in the box of Saran Wrap (registered trademark), which is a product of Asahi Kasei Co., Ltd., there is a thing with a configuration that prevents the film roll from jumping out of the box by protrusions provided on both end faces in the longitudinal direction. These protrusions are merely means for preventing popping out, have no function of smoothing the rotation of the film roll, and cannot solve the above problems.
JP 05-229553 A JP 2002-326628 A

  The present invention has been made in view of the above, and prevents a packaging film roll housed in a container so as to roll freely from rotating poorly, excessively rotating, or reversely rotating. An object of the present invention is to provide a packaging film roll container that can be pulled out of the container by an arbitrary length and cut.

As described above, the invention according to claim 1 is a container that accommodates a packaging film roll including a hollow cylindrical core body and a wrap film wound around the core body in a roll shape, The container includes a box body having an open portion on one side surface, a box body provided with a lid body that is openably and closably supported at one end edge of the open portion, and disposed on both end faces of the box body. A small-diameter shaft member that freely fits into both opening portions of the accommodated packaging film roll and rotatably supports the packaging film roll, and the height position of the shaft member is the box body of the supported packaging film roll. It is set to float from the bottom of the body.
The invention of claim 2 is characterized in that, in claim 1, the shaft member is detachably attached to at least one of both end faces of the box body.
According to a third aspect of the present invention, in the first aspect, the shaft member is formed by projecting part of both end faces of the box body inward.

According to the first aspect of the present invention, the packaging film roll is supported by the shaft member as the protrusion provided on the both end surfaces in the longitudinal direction of the container in a state where the packaging film roll is rotatably lifted. It is possible to prevent the film roll from being rotated, excessively rotated, or reversely rotated, and to draw one end of the film roll out of the container by an arbitrary length and cut it. Moreover, it can prevent that a film roll rolls out of a box body during use.
According to the invention of claim 2, since the shaft member is configured to be detachable, when the user thinks that the shaft member is unnecessary, the film member is removed and the film roll is seated on the inner bottom surface of the box body. It can also be used in the state. In addition, when the film roll is taken in and out of the box, the shaft member is removed to facilitate taking in and out.
According to the invention of claim 3, since it is not necessary to use a shaft member as a separate member, the number of parts can be reduced and the cost can be reduced.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
1 (a), (b), (c), and (d) are a perspective view of a packaging film roll container according to an embodiment of the present invention in a closed state, a perspective view in an open state, a cross-sectional view of main parts, and a shaft member. It is sectional drawing which shows the state which supported the packaging film roll.
This packaging film roll container 1 includes a packaging film roll 2 including a hollow cylindrical core body 3 made of cardboard and the like, and a wrap film 4 wound around the outer periphery of the core body 3 in a roll shape. It is a container which accommodates. The container 1 includes a box body 11 made of cardboard and having an open portion 12 on one side of the four sides, and a lid body 13 that is supported at one end edge of the open portion 12 so as to be opened and closed. 10 and a small-diameter shaft member 15 that loosely fits in openings at both ends of the packaging film roll 2 disposed and accommodated on both longitudinal end faces 11a of the box body 11 and rotatably supports the packaging film roll. I have. The height position of the shaft member 15 attached to the end surface 11a is such that when the shaft member 15 supports the packaging film roll by being inserted into the openings at both ends of the core body 3, the bottom of the packaging film roll 2 is the bottom surface of the box body. It is set to always float (non-contact) from. And since the diameter of the shaft member 15 is remarkably smaller than the both-ends opening diameter of the core 3, the shaft member 15 can be supported so that the packaging film roll 2 rotates smoothly.
Therefore, even when the weight and diameter of the film roll 2 are large because the remaining amount of the wrap film 4 is large as at the start of use, there is no contact resistance with the inner bottom surface of the box body 11, so that the opening portion When the end 4 a of the wrap film 4 is pulled from the end 12 a predetermined length, the packaging film roll 2 can be easily and stably rotated in the pulling direction, pulled out by an arbitrary length, and provided at the leading edge of the lid 13. It can be easily cut by the cutter 14. At this time, there is no possibility that the portion pulled out by wrinkling, folding, or skewing of the wrap film becomes unusable due to rotation failure or reverse rotation of the packaging film roll 2. In particular, even when the remaining amount of the wrap film is reduced, excessive rotation, reverse rotation, wrinkle, folding, and skew are effectively prevented. Moreover, it can prevent that a film roll rolls out of a box body during use, and can improve usability.
The shaft member 15 is made of, for example, resin, wood, paper, or the like, and may be fixed in advance to the end surface 11a of the container made of cardboard or the like, or a hole provided in the end surface 11a as shown in FIG. On the other hand, it may be attached or detached from the outside, or may be supported so as to protrude inward and outward.

By detachably configuring the shaft member, if the user thinks that the shaft member is unnecessary, it can be removed and used with the film roll seated on the inner bottom of the box body. Convenient. In addition, when the film roll is taken in and out of the box, the shaft member is removed to facilitate taking in and out.
Further, as shown in FIG. 3, a part of cardboard constituting the end surface 11 a may be cut and raised to form a protrusion, which may be used as the shaft member 15. According to this, since it is not necessary to use the shaft member as a separate member, the number of parts can be reduced and the cost can be reduced.
Furthermore, as a mounting structure of the shaft member to the box body, as shown in FIG. 4, the part 20 including the shaft member 15 is slidably mounted in the notch 11b provided in the end surface 11a of the box body 11. It may be. The part 20 may be detachable or may be fixed in the notch 11b.
