Of these, the roll body pop-out prevention tool 10 is integrally formed of an elastic synthetic resin, and has a long plate rectangular base portion 11 extending in the width direction and a substantially C-shaped side view from the front and rear end edges thereof. A pair of pressing portions 12 and 12 that are curved outward and extend upward, respectively, and a side view that extends downward after facing toward each other from the upper end edges of the pair of pressing portions 12 and 12. It is composed of top walls 13 and 13 formed in an inverted L shape and an operation unit 14 extending upward from one end edge in the width direction of the base portion, and its weight. Is secured so that the roll body R does not float until the wrap film F is used up.

It should be noted that the top wall 13 here rotates without blurring when the wrap film F is pulled out by balancing the weight with the base portion 11 and making the cross-sectional center of gravity substantially coincide with the cross-sectional center of gravity of the roll body. It also serves as a stopper to prevent the pressing portions 12 and 12 from coming into contact with each other and further deforming when they are brought close to each other, but it is not essential.

Next, the storage box 90 is formed by bending a thick paper material, and has a box main body 91 that opens upward and a lid that extends from the rear upper end edge of the box main body 91 to openably cover the opening. It is composed of a body 92 and.

Specifically, the box body 91 is composed of a rectangular bottom plate 91a that is long in the width direction, a front wall plate 91b, a rear wall plate 91c, and side wall plates 91d / 91d that are erected from the peripheral edge of the bottom plate 91a. The lid 92 is composed of a top plate 92a formed to be one size larger than the bottom plate 91a, a front lid plate 92b extending downward from the peripheral edge thereof, and horizontal lid plates 92d and 92d.

Has been done.

The roll body R stored in the storage box 90 is composed of a winding core M and a wrap film F for food packaging wrapped around the winding core M, and is stored in the storage box 90 and then in a required amount. The wrap film F is pulled out and cut out with a saw blade 93 for use.

The storage box 90 and the roll body R housed in and used in the storage box 90 are already well known. Therefore, only the above description will be given, and details will be omitted.

The front side here is the side to which the saw blade 93 is attached with the lid body 92 closed with reference to the storage box 90, and the rear side is the side where the lid body 92 and the box body 91 are connected in series. The side, the left-right direction, or the width direction means the side orthogonal to the front and back in the horizontal direction. Further, in the roll body R or the roll body pop-out prevention tool 10, this width direction may be referred to as a length direction, and the front-rear direction may be referred to as a front-rear width. Further, the radial direction is based on the axial center of the roll body R. Further, the inside of the winding core M may be expressed as the inside of the roll body R. This also applies to the description of the following embodiments.

Next, a mode of using the roll body pop-out prevention tool 10 of the present embodiment will be described with reference to the drawings.

<How to wear>
First, the roll body R is taken out from the storage box 90 and held in one hand.

Next, grasp the roll body pop-out prevention device 10 with the other hand and apply a light force to grasp it. Then, as shown in FIG. 2 (a), the pressing portions 12 and 12 which are separated from each other in the normal state are elastically deformed, and as shown in FIG. 2 (b), the inner edge edges of the top walls 13 and 13 of each other are elastically deformed. Reach the position where

As a result, the dimension of the front-rear width of the roll body pop-out prevention tool 10 becomes smaller than the inner diameter of the winding core M of the roll body R.

In this state, the roll body pop-out prevention tool 10 is inserted into the winding core M, and when the hand held at the time of inserting the roll body pop-out prevention tool 10 is released to some extent, the pressing portions 12 and 12 are in the original state as shown in FIG. 2 (c). It is pressed against the inner peripheral wall of the winding core M in an attempt to return to. That is, the force that presses the pressing portions 12 and 12 toward the inner peripheral wall of the winding core M is the restoring force of the roll body pop-out prevention tool 10 itself that has elastic force in the present embodiment, and this is used as the urging means. It is said.

From here, the operation unit 14 is pushed in with a fingertip and arranged at a substantially central portion in the length direction of the roll body R as shown in FIG. 2 (d). All that is left is to return the roll body R to which the roll body pop-out prevention device 10 is attached to the original storage box 90.

<how to use>
The roll body R to which the roll body pop-out prevention device 10 is attached can be used in the same manner as the normal roll body R. That is, as shown in FIG. 3A, the lid 92 is opened, the tip of the wrap film F wound around the roll R is grasped, the required amount is pulled out, and the lid 92 is attached to the lower end of the closed lid 92. Just cut with the saw blade 93. Even if such work is performed, the roll body pop-out prevention tool 10 of the present embodiment is housed in the roll body R, so that the work is not hindered at all.

Further, even if the wrap film F is torn and the roll body R needs to be taken out from the storage box 90 for the repair work, the storage box 90 is tilted and the roll body R is also tilted in the same manner as in the normal work. All you have to do is take out the work, and there is no additional work to be done.

Then, when the amount of the wrap film F decreases and the weight of the roll body R becomes lighter during use in this way, the roll body usually loses the adhesive force of the wrap film F when the wrap film F is pulled out. Peeling from R is not performed well and the roll body R comes to float, and finally when the wrap film F is pulled out, a problem that the wrap film F pops out from the storage box 90 begins to occur. In the case of the roll body R equipped with the roll body pop-out prevention tool 10, a sufficient weight is always secured by the roll body pop-out prevention tool 10 to prevent lifting. Therefore, it can be used comfortably until the end without popping out as in the case of the beginning of use.

<How to take out>
When the roll body pop-out prevention tool 10 of the present invention is taken out from the roll body R which has been used and has only the winding core M. First, the storage box 90 is tilted to take out the winding core M, and the operation portion 14 of the roll body pop-out prevention tool 10 mounted inside is pushed into the back with a fingertip as shown by an arrow in FIG. 3 (b). ..

Then, the end of the roll body pop-out preventive tool 10 comes out from the opening on the opposite side of the winding core M, so grasp and grasp it. With this, as shown in FIG. 2B described in <Mounting method>, "the position where the top walls 13 and 13 of each other come into contact with each other is reached, and the dimension of the front-rear width of the roll body pop-out prevention tool 10 is the roll body R. Since it is in a state smaller than the inner diameter of the winding core M, it is sufficient to pull it out as it is.

As described above, the roll body pop-out prevention tool according to the present invention can be attached and detached by a simple operation of simply inserting it into the roll body and pulling it out.

In addition, since the entire roll is stored in the roll, it does not get in the way when the wrap film is pulled out, and even if the roll itself needs to be taken out of the storage box due to some trouble, it can be smoothly taken out. It also has the advantage that it can be taken out.

If the total length of the roll body pop-out prevention tool 10 is formed to be slightly shorter than the length of the roll body R, the operation unit 14 provided on one end side can be pressed with a fingertip as described above. When pressed, the other end comes out from the opening on the opposite side of the winding core M, so that it can be easily taken out. However, the present invention is not limited to this, and even if the other end of the roll body pop-out preventive tool is formed so short that it does not come out from the opening on the opposite side when the fingertip is pushed in until it cannot reach, for example, it is different. A rod-shaped body may be provided and used to push it into the center to attach it, or to push it to the opposite side to take it out.

Further, the operation unit 14 may be formed in an L-shape in front view so that it can be used not only for pushing but also for pulling out, and can be taken out from the inserted side.

The roll body pop-out prevention device of the present invention may be attached to the roll body before using the new wrap film, or may be performed after the roll body is felt to be lifted during use.

The storage box 90 and the roll body R housed in and used in the storage box 90 are already well known. Therefore, only the above description will be given, and details will be omitted.

The front side here is the side to which the saw blade 93 is attached with the lid body 92 closed with reference to the storage box 90, and the rear side is the side where the lid body 92 and the box body 91 are connected in series. The side, the left-right direction, or the width direction means the side orthogonal to the front and back in the horizontal direction. Further, in the roll body R or the roll body pop-out prevention tool 10, this width direction may be referred to as a length direction, and the front-rear direction may be referred to as a front-rear width. Further, the radial direction is based on the axial center of the roll body R. Further, the inside of the winding core M may be expressed as the inside of the roll body R. This also applies to the description of the following embodiments.

Next, a mode of using the roll body pop-out prevention tool 10 of the present embodiment will be described with reference to the drawings.

<How to wear>
First, the roll body R is taken out from the storage box 90 and held in one hand.

Next, grasp the roll body pop-out prevention device 10 with the other hand and apply a light force to grasp it. Then, as shown in FIG. 2 (a), the pressing portions 12 and 12 which are separated from each other in the normal state are elastically deformed, and as shown in FIG. 2 (b), the inner edge edges of the top walls 13 and 13 of each other are elastically deformed. Reach the position where

As a result, the dimension of the front-rear width of the roll body pop-out prevention tool 10 becomes smaller than the inner diameter of the winding core M of the roll body R.

In this state, the roll body pop-out prevention tool 10 is inserted into the winding core M, and when the hand held at the time of inserting the roll body pop-out prevention tool 10 is released to some extent, the pressing portions 12 and 12 are in the original state as shown in FIG. 2 (c). It is pressed against the inner peripheral wall of the winding core M in an attempt to return to. That is, the force that presses the pressing portions 12 and 12 toward the inner peripheral wall of the winding core M is the restoring force of the roll body pop-out prevention tool 10 itself that has elastic force in the present embodiment, and this is used as the urging means. It is said.

From here, the operation unit 14 is pushed in with a fingertip and arranged at a substantially central portion in the length direction of the roll body R as shown in FIG. 2 (d). All that is left is to return the roll body R to which the roll body pop-out prevention device 10 is attached to the original storage box 90.

<how to use>
The roll body R to which the roll body pop-out prevention device 10 is attached can be used in the same manner as the normal roll body R.

Since it is in a state smaller than the inner diameter of the winding core M, it is sufficient to pull it out as it is.

As described above, the roll body pop-out prevention tool according to the present invention can be attached and detached by a simple operation of simply inserting it into the roll body and pulling it out.

In addition, since the entire roll is stored in the roll, it does not get in the way when the wrap film is pulled out, and even if the roll itself needs to be taken out of the storage box due to some trouble, it can be smoothly taken out. It also has the advantage that it can be taken out.

If the total length of the roll body pop-out prevention tool 10 is formed to be slightly shorter than the length of the roll body R, the operation unit 14 provided on one end side can be pressed with a fingertip as described above. When pressed, the other end comes out from the opening on the opposite side of the winding core M, so that it can be easily taken out. However, the present invention is not limited to this, and even if the other end of the roll body pop-out preventive tool is formed so short that it does not come out from the opening on the opposite side when the fingertip is pushed in until it cannot reach, for example, it is different. A rod-shaped body may be provided and used to push it into the center to attach it, or to push it to the opposite side to take it out.
