Abstract

PURPOSE:To pull out wrapping film from its storage case, spread it out into a plane condition and cut off the film as-spread by a light force. CONSTITUTION:Wrapping film W is pulled out from its storage case body 11 through a gap between a front side plate 18 and a covering piece 15 and spread out horizontally, the covering plate 15 is pressed with the thumb of the left hand and the wrapping film W is pulled to be tensioned in the horizontal direction. In this way the wrapping film W is cut at its intermediate part in the lateral direction by the highest point C of a V-shaped saw-toothed edge formed on the side edge of the covering piece 15. The wrapping film W is thereafter further pulled horizontally to allow the cut to progress widthwise and the film is cut off with a neatly V-shaped edge. Since the wrapping film W is cut off neatly in a flatly spread condition, the film as-spread can be placed gently over an article to be wrapped.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case for wrapping a wrap film used for food packaging or the like in a cylindrical shape and storing the wrap film. The present invention relates to a wrap film storage case that can be used.

[0002]

2. Description of the Related Art FIG. 8 is a perspective view showing a conventional wrap film storage case. This conventional example is, for example, Jikken Sho 61.
-22823 and the same kind as what is indicated by it. In FIG. 8, reference numeral 1 is a case main body formed in a rectangular parallelepiped box, and a wrap film W wound in a cylindrical shape on the peripheral surface of the core is stored inside the case main body. A lid 4 that covers the opening 3 is joined to the back plate 2 of the case body 1. A cover lid piece 6 that overlaps the front side plate 5 of the case body 1 is provided at the tip of the lid body 4, and a metal cutting member 7 is attached to the tip end portion of the cover lid piece 6.
The cutting member 7 has a saw blade at its tip, and this saw blade slightly protrudes from the tip of the covering lid piece 6 and extends parallel to the bottom side 1a of the case body.

[0003]

The cutting operation of the wrap film in the conventional wrap film storage case will be described in detail. For convenience of explanation of the operation, as shown in FIG.
Stack the Cartesian coordinates XYZ on the storage case. X axis is dorsal plate 2
And the axis perpendicular to the surface of the front side plate 5, the direction from the back side plate 2 to the front side plate 5 is (+), and the direction from the front side plate 5 to the back side plate 2 is (-). The Y-axis is an axis perpendicular to the surfaces of the lateral side plates 8 and 9, and the direction from the lateral side plates 8 to 9 is (+),
The direction from the side plates 9 to 8 is (-). The Z-axis is an axis perpendicular to both the X-axis and the Y-axis, and extends from the bottom side 1a to the opening 3
(+), And the direction from the opening 3 to the bottom side 1a is (-).

The cutting operation in the conventional lap film storage case after the XYZ axes are superposed in this way will be described. First, grab the storage case with your left hand. Next, the end of the wrap film W is grasped with the right hand and pulled out in the (+) direction of the X axis in the XY plane. Next, the right hand grasps the vicinity of the A position shown in FIG. 9, and an appropriate tension T is applied in the X axis direction near the A position of the wrap film W by the force of the left hand and the right hand. Next, with the left hand, the vicinity of the position a of the storage case is lowered in the (−) direction of the Z axis, and the right hand is slightly raised in the (+) direction of the Z axis while slightly increasing the tension T. As a result, the wrap film W is cut at the portion B of the cutting member 7, and the cutting line of the film extends along the cutting member 7 in the (−) direction of the Y axis. This is a cutting operation, and the cut wrap film W is put on the food or the like placed on the plate. However, the following problems are likely to occur in this operation.

That is, where the wrap film W may be covered with food while being opened along the XY plane, the vicinity of the position a of the storage box is lowered in the Z-axis (-) direction with the above-mentioned left hand. At the same time, when the right hand is slightly raised in the Z-axis (+) direction and the tension T is slightly increased, the right hand is often lowered in the Z-axis (-) direction and raised in the Z-axis (+) direction. The motion is too large, or the amount of increase in the tension T is too large, so that the cut wrap film W cannot be kept in a state of being spread in the XY plane, and the wrap film is held by the right hand. It becomes impossible to obtain an area sufficient for W to be wrinkled or entangled and hang down to cover food or the like. The above problem is a problem to be solved by the invention.

The present invention solves the above-mentioned problems of the prior art by simply pulling the wrap film pulled out from the case body in the + X direction, which is horizontal to the case body, without extremely lifting it in the + Z direction. The present invention provides a wrap film storage case that can cleanly cut a wrap film, and prevents wrinkles from being formed on the wrap film after cutting and the film from becoming stuck and sticking.

[0007]

In order to achieve the above object, according to the present invention, a lid body that covers an opening of the case body is joined to a case body in which a wrap film wound in a cylindrical shape is accommodated. In addition, in a wrap film storage case in which a cover lid piece that overlaps with the front side plate of the case body is continuously provided at the tip of the lid body, a cutting member is attached to the tip of the cover lid piece. The intermediate portion has a projecting shape that is closer to the bottom side of the case body than both end portions.

[0008]

In this wrap film storage case, if the wrap film is pulled out from the case body and sandwiched between the front side plate of the case body and the cover lid, and the wrap film is pulled in the horizontal (X) direction with respect to the case body, A notch is formed in the central portion of the wrap film by the projecting cutting member, and when the wrap film is pulled in the + X direction as it is, the notch extends along the cutting member in the film edge direction and can be cut into a V-shape to some extent. Therefore, after cutting the wrap film,
When there is a wrinkle, it is not necessary to spread the wrinkle with both hands, and the wrap film spreads in a shape along the horizontal plane in the state of being cut. Therefore, by lowering the wrap film as it is horizontally onto an article to be packaged such as food, it is possible to cover the food with a wrap film having a sufficient area.

In FIG. 1 and FIG. 2, reference numeral 11 is a case body. The case main body 11 is formed of paper into a rectangular parallelepiped box shape, and the upper side thereof has an opening 12
Has become. A lid 14 that covers the opening is integrally joined to the upper end of the back plate 13 of the case body 11. At the front end of the lid body 14, a covering lid piece 15 and an unsealing piece 17 joined to the covering lid piece 15 by perforations 16 are provided. In addition, the side cover lid pieces 20 are provided on both ends of the lid body 14.
a and 20b are provided. As shown in FIG. 3, in the state before the case is opened, the back surface of the opening piece 17 and the front surface of the front side plate 18 of the case body 11 are bonded by the glue 19 at several spots. A wrap film W wound around a cylindrical core 22 is housed in the case body 11. The wrap film W is, for example, a vinylidene chloride-based, vinyl chloride-based, or butadiene-based synthetic resin film.

A metal cutting member 21 is attached to the back surface of the edge of the cover lid piece 15. A saw blade 21a is formed at the tip of the cutting member 21.
Protrudes from the edge of the covering lid piece 15, and the saw blade 21a is located on the back side of the unsealing piece 17 in the state shown in FIGS. The cutting member 21 has a projecting shape in which the central portion C approaches the direction of the bottom side 11a of the case body 11. That is,
In the embodiment of FIGS. 1 and 2, the central portion C of the cutting member 21 is an edge, and the cutting members located on both sides of this edge are inclined linearly with respect to the bottom side 11a of the case body 11 and extend linearly. Has become. Corresponding to this, the perforation 16 serving as the boundary between the covering lid piece 15 and the unsealing piece 17 is also formed in a protruding shape, and the covering lid piece 15 has a substantially triangular shape.

Further, as shown in an enlarged manner in FIG. 5, the front side plate 18 of the case body 11 has its upper edge portion bent inward of the case, and the bent piece 18a and the back surface of the front side plate 18 are separated from each other. It is adhered by the adhesive tape 23. As shown in FIG. 2, a cutout 18b is formed in the front side plate 18, and the adhesive tape 23 is exposed in the cutout 18b. The adhesive tape 23 exposed from the notch 18b allows the wrap film W, which is pulled out from the case body 11 and cut and remains, to be the front plate 18.
Function to hold in position. Further, the cover piece 1
The U-shaped notch 15a is made in 5 and the portion sandwiched by the notch 15a is the pressing piece 1.
It is 5b. As shown by the chain line in FIG. 5, the pressing piece 15b can be deformed inward of the covering piece 15. When the pressing piece 15b is pressed by a finger when the wrap film W is cut by the cutting member 21, the pressing piece 15b is deformed inward, and the wrap film W pulled out in front of the front side plate 18 is inside the cutout 18b. Although it is pressed against the adhesive tape 23, the rectangular coordinates XYZ are overlaid on the storage case as shown in FIGS. 1, 2, 6, and 7 for convenience of explanation of the usage. The X axis is an axis perpendicular to the surfaces of the back plate 13 and the front plate 18,
The direction from the back side plate 13 to the front side plate 18 is (+), and the direction from the front side plate 18 to the back side plate 13 is (-). The Y-axis is the axis perpendicular to the surfaces of the lateral plates 28 and 29, and
The direction from 8 to 29 is (+), and the direction from the lateral side plates 29 to 28 is (-). The Z axis is an axis perpendicular to both the X axis and the Y axis, and the direction from the bottom side 11a to the opening 12 is (+), and the direction from the opening 12 to the bottom side 11a is (-).
Is.

A method of using the storage case for the wrap film W according to the above-described embodiment after the XYZ axes are superposed in this manner will be described. When the case is opened, the opening piece 17 adhered to the front side plate 18 of the case body 11 is peeled off and separated from the covering piece 15 along the perforations 16.
When the unsealing piece 17 is removed, as shown in FIG.
The saw blade 21a of the cutting member 21 is exposed from the edge portion of No. 5. After removing the unsealing piece 17, the upper edge H of the back plate 13 of the case body 11 serves as a hinge, and the lid 14 and the covering piece 15 can be opened and closed with respect to the opening 12 of the case body 11.

After opening the case, the wrap film W wound around the core 22 is pulled out from between the front side plate 18 and the covering lid piece 15. After pulling out the wrap film W for the required length,
For example, as shown in FIG. 6, the storage case is held by the left hand and the covering piece 15 is pressed with the thumb. Alternatively, the lid 14 is pressed with the thumb. Further, the wrap film W grasps the central portion of the tip portion thereof with the right hand. Since the saw blade 21a of the cutting member 21 protruding from the edge of the covering piece 15 has a projecting shape whose center portion C is an edge, when the center portion of the wrap film W is pulled in the + X direction with the right hand, the saw blade 21a The central portion of the wrap film W is cut by the edge of the central portion C of 21a. When the wrap film W is pulled as it is, the notch advances in the direction of both edges of the film along the saw blade 21a, and the wrap film W is cut cleanly. In this way, the wrap film W can be cut simply by pulling it in the + X direction with respect to the storage case, so that the wrap film W after cutting does not have wrinkles or the films do not adhere to each other in a twisted state. Therefore, if you wrap the wrap film W after cutting with your right hand directly toward the food or items to be packaged such as trays, the wrap film W will have a substantially horizontal (XY plane) sufficient area. And is installed on the article to be packaged. The above is the method of using the storage case of the present invention.

Further, when the wrap film W is cut in the state of FIG. 6, if the pressing piece 15b formed by the notch 15a of the covering lid piece 15 is pressed with the thumb of the left hand, the pressing piece 15b is pushed to the back side thereof. The positioned wrap film W can be pressed into the notch 18b formed in the front plate 18 of the case body 11. Therefore, the wrap film W left between the cover lid piece 15 and the front plate 18 after the cutting is completed is held by the adhesive tape 23 in the notch 18b, and the wrap film W is completed after the packaging is completed. It is prevented from being rewound inside.

In the second embodiment shown in FIG. 7, the covering piece 15 and the cutting member 21 attached to the covering piece 15 are made to project in a substantially trapezoidal shape at the center thereof. In this case, the method of cutting the wrap film W is the same as that of the embodiment shown in FIG. 6, and the saw blade 21a located at the trapezoidal protrusion J is simply pulled by pulling the central part of the film in the horizontal direction. Thus, the wrap film W is cut from the central portion and cut cleanly. Further, in this second embodiment, if the front side plate 18 of the case body 11 is provided with a substantially arcuate cutout 18c, after the wrap film W is cut by a required length, the protrusion J is formed in the cutout 18c. Will be able to plug in. With this, the lid 14 when not in use
Can be prevented from opening.

In each of the illustrated embodiments, the cutting member 2 is used.
1 has a shape that is deformed at an acute angle such as a substantially triangular shape or a trapezoidal shape, but it is also possible that the cutting member 21 is formed in an arc shape and the central portion thereof projects. Further, the edge of the central portion C shown in the embodiment of FIG. 2 or the protruding portion J in the embodiment of FIG. 7 does not necessarily have to be provided at the center of the cutting member 21, and may be provided in any of the longitudinal directions of the case. It may be provided in a biased position.

[0018]

As described above, according to the present invention, since the cutting blade provided at the edge of the covering lid piece has a protruding shape, a force in the + X direction is applied to the wrap film surface pulled out from the case body to the ZY surface. In addition, even if the film surface is not lifted in the + Z direction, the central portion of the film is first cut by the protruding portion of the blade only by pulling in the + X direction, and the cut can reach both sides and be cut cleanly. Therefore, wrinkles do not occur in the film after cutting, and the films do not stick to each other while being twisted, and the wrap film after cutting spreads almost in the XY plane and it is not necessary to spread it with both hands. It becomes possible to cover the article to be packaged.
