Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a roll-shaped film pull-out tool and a roll-shaped film winder, and more particularly to a transparent thin-film polymer film or thin-film aluminum film, which is often used for packaging fresh foods. The present invention relates to a roll-shaped film draw-out tool that is rolled into a roll and is commercially available, and such a roll-shaped film winding body.

[0002]

[Prior Art]

 Today, a transparent thin film polymer film or a thin aluminum film material, which is wound into a roll, is often used as a means for packaging foods in the kitchen or supermarkets. Such a film material is packaged and shipped after a long strip is wound around a predetermined winding core for a predetermined length in a factory. The winding operation in the factory is carried out with a certain tension applied to the rolled film in order to minimize the bulk of the wound film and to prevent the wound film from wrinkling. Due to the fact that there is almost no air between the layers of the film that has been wound up, the two films are in close contact with each other.

[0003]

[Problems to be solved by the device]

 As described above, the factory-rolled and packaged roll-shaped film roll is wound so that the films are closely adhered to each other, so that the user opens the package and first uses the film. At the time, that is, when trying to pull out the rolled film from the leading edge to the outside of the package, it is extremely difficult to find the leading edge, and after finding the leading edge, the film is tried to be pulled from the portion. In this case, it is almost impossible to apply the same stress over the entire width of the film. Therefore, at the beginning of use, it is tens of centimeters from the winding end, and in some cases about 1 m is wrinkled or folded. Everybody is experiencing the fact that it has to be pulled out and that part is wasted.

Further, even when the winding tip can be pulled out almost uniformly, static electricity is generated due to peeling between the films in the case of a polymer film, and the static electricity is used to package foods and the like. It is also experienced that the film may bend and become partially adhered at the moment of doing so, and similarly, the film may not be usable. The present invention is intended to solve the above-mentioned problems of a commercially available roll-shaped film winding body, and more specifically, to ensure that the tip of the roll-shaped film winding body is not wasted at the beginning of use. The aim is to provide a drawer that can be easily pulled out. Another object of the present invention is to provide a roll-shaped film winding body having such a drawer as a separate member.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems and to achieve the object, the present invention is a rod-shaped body having a width substantially the same as the width of a film wound in a roll, the length of which is at least a part of the peripheral wall. Disclosed is a roll-shaped film pulling tool having a bondable region extending over substantially the entire length in the direction.

The rod-shaped body may be formed as a member different from the member forming the roll-shaped film, and the rod-shaped body may be formed by the core itself of the film wound in a roll shape. You may. Further, a thin film resin film layer of the same kind or the same kind as the film wound around the outer peripheral surface of the rod-shaped body is formed by means such as winding, and the bondable region is formed on the thin film resin film layer. You may do it.

The present invention further provides a cylindrical core, a rod-shaped body which is inserted into the core and has a width substantially the same as the width of the film wound around the core, and the peripheral wall of which is small. Also disclosed is a roll-shaped film winding body having at least a pulling tool having a bondable region extending over substantially the entire length thereof in a part thereof. There are no particular restrictions on the type and material of the roll-shaped film, but it is particularly effective in the case of a roll of a transparent thin-film polymer film or thin-film aluminum film that is already commercially available as described above. The present invention can also be effectively applied to a film winding body in which resin films are superposed in a double layer and a large number of bags are continuously formed in the length direction.

The bondable region may be formed in a predetermined width over at least a part of the peripheral surface portion of the rod-shaped member over substantially the entire length in the lengthwise direction of the rod-shaped member. An appropriate adhesive may be applied to the surface of the rod-shaped member. It may be applied to the surface of the rod-shaped body or a so-called double-sided adhesive tape may be adhered to the surface of the rod-shaped body. In addition, it is not necessary that all the regions of this bondable region have the same adhesiveness, and they may be formed in spots in the length direction of the rod-shaped body.

After opening the package of the roll-shaped film winding body, the user makes the drawer according to the present invention substantially parallel to the axis of the roll-shaped film winding body so that the end of the film can be easily moved. If it is recognizable, place it near the leading edge, or if the leading edge is unclear, place it at an appropriate position on the surface of the roll-shaped film, and then use either the roll film or the drawer as necessary. Rotate both properly. As a result, the adhesive component in the bondable area formed on the surface of the drawer is attached to the surface of the roll-shaped film. The adhesion is equal and occurs simultaneously over the width of the film. After that, the user can lift the leading end portion of the wound film almost at the same time by lifting the pulling tool from the roll-shaped film winding body. By moving the drawer and pulling out the film as it is, the user can cover the film on the packaged object, and the roll-shaped film winding body can be used without wasting the leading end of the film. You can start using.

Further, when a thin resin film layer is formed on the outer peripheral surface of the rod-shaped body, the thin resin film of this kind is easily charged with static electricity, and is caught by the action of the static electricity. It is possible to more easily pull out the leading end of the film that has been removed.

[0011]

[Action]

 When the film winding core itself is configured as a drawer, the film-wound core can be used as a drawer for a roll-shaped film winding body to be used next, and When the drawer is constructed as a separate member, it is packaged in the factory with the drawer inserted into the hollow part of the hollow core of the film to form a roll-shaped film roll, and in that state the market May be provided to

[0012]

【Example】

 Hereinafter, the present invention will be described in more detail based on examples. FIG. 1a shows a winding body a 1 in which a transparent thin film polymer film is wound into a roll, and is composed of a film body 1 and a winding core 2. In the figure, the leading edge portion 10 of the film is shown in a state of being floated up from the main body portion of the film that has been rolled up, but immediately after the user purchases and opens the package, the leading edge portion 10 is rolled up. The actual condition is that it is in close contact with the surface of the film body. As the winding core 2, a cardboard molded into a hollow cylinder or a resin material similarly molded is used.

FIG. 1b shows an embodiment of a drawer according to the present invention. The pull-out tool b of this embodiment is obtained by improving the winding core 2 of the winding body shown in FIG. 1a. The adhesive 4 forming the bondable region is applied over substantially the entire length in the depth direction. In the case of this embodiment, when the roll-shaped film winding body is manufactured in the factory, the core 2 to which the adhesive 4 is applied is prepared, the film is wound, and then the package is shipped. When the user finishes using the film of the wound body that he has purchased, he will have at hand a winding core having an adhesive applied to the peripheral wall surface. Then, the next film package is opened, and the above-mentioned winding core, that is, the pull-out tool b of the present invention is brought into contact with the roll surface portion of the new winding body a in a state in which their respective axial cores are aligned. Rotate the pullout tool b slightly if necessary. As a result, the adhesive 4 provided on the surface of the drawer b simultaneously adheres to the surface of the roll-shaped film 1 over the entire area in the width direction. By pulling out the pull-out tool b laterally from the package (not shown) in this state, the film can be pulled out without wasting the leading end of the film as shown in FIG. 1c.

FIG. 2 shows another embodiment of the drawer according to the present invention. The pull-out tool c is prepared especially as a pull-out tool, that is, it is made as the base material 20 of the pull-out tool by using a unique member instead of the core of the roll film. The material of the base material 20 is not particularly limited, and an appropriate material such as a paper material or a resin material having a required rigidity can be used. Further, although the cross-sectional shape is shown as a square shape in the drawing, it may be any shape such as a circle, an ellipse, and a triangle. The length of the pull-out tool c is approximately equal to or slightly longer than the lateral width of the target roll film, and at least part of the outer peripheral wall of the pull-out tool c is almost entirely in the lengthwise direction as in the embodiment shown in FIG. The adhesive layer 24 is formed. The method of using the drawer tool c is almost the same as that of the above-mentioned embodiment, and the description thereof is omitted.

FIG. 3 shows another embodiment of the present invention. In this example, the drawer c shown in FIG. 2 is inserted into the hollow portion of the winding core 2 of the film winding body a. At the manufacturing plant, a roll-shaped film winder and a drawer as shown in Fig. 2 are manufactured, the drawer is inserted into the winding core of the winder, packaged, and then shipped to the market. After the user has finished using the film, the user can take out the pull-out tool c from the winding core and use the pull-out tool c as the pull-out tool for the next winding body in the same manner as shown in FIG.

The above description merely shows the preferred embodiments of the roll-shaped film drawer and roll-shaped film winding body according to the present invention, and there are many other modifications. For example, although not particularly shown, in the case where the film core is used as a drawer, by forming the core with an elastic body such as a thin sponge attached to the surface, the film can be used as a drawer more. The function can be improved. Further, the area where the adhesive is located is not limited to a part of the outer peripheral wall of the rod-shaped member, and it may be formed on the entire surface thereof, and the adhesive to be provided does not need to be provided over the entire area in the length direction and the width direction. It will be easily understood that the object can be sufficiently achieved even if it is provided in a scattered manner such as almost both end portions and the central portion.

Further, the means for molding the bondable region may be a means for applying the adhesive itself as described above, or one side of a so-called double-sided tape may be adhered to a rod-shaped body and used as a drawer. At times, a means for exposing the bondable region to the other surface by removing substantially the film coated on the other surface can be effectively used.

Further, as described above, a thin film resin film layer can be formed on the outer peripheral surface of the rod-shaped body. In this case, the thin film resin film of this type is easily charged with static electricity. Therefore, it becomes possible to more easily pull out the front end portion of the film that has been caught by the action of the static electricity. At that time, the thin film resin film layer may be constituted by itself, or an adhesive or a double-sided tape may be applied or adhered to a part of the surface of the thin film resin film layer.

Further, a state in which a conventional roll-shaped film winding body and an independent drawer as shown in FIG. 2 are separated in the same package, that is, a state in which the drawer is not inserted in the core of the film winding body. It will be apparent that the present invention also includes a roll-shaped film winding body packaging body encapsulated in (4).
