Description

  TECHNICAL FIELD The present invention relates to a film end drawing method and a drawing tool that can easily draw out a film end closely adhered to a side surface of a roll film in which a food wrap film or the like is wound in a cylindrical shape.

  A film such as a food wrap has a plastic film having a thickness of several tens of μm wound in a cylindrical shape (hereinafter referred to as a roll film). And when the edge part of a film contacts the side surface of a roll film, a film edge part will be in contact | adherence state by the effect | action of static electricity. For this reason, it has been difficult to detect the film edge. In addition, if the end of the detected film is finally pinched and peeled off, the film tears from the pinched part and often cannot be pulled out evenly. As described above, it is very troublesome to pull out the film end portion in the close contact state from the roll film.

  On the other hand, when this type of roll film is used as a food wrap film, it is stored in a storage box provided with a cutter for cutting the roll film. Then, a necessary length is pulled out from the storage box and cut with a cutter. In such a storage box, contrivances have been made to prevent the roll film from rewinding or inadvertently jumping out so that the end of the film does not adhere to the side surface of the roll film.

  For example, in the carton for a wrap film described in Patent Document 1, an anti-rewind layer is provided on the side wall at a position where the wrap film is cut. Then, the wrap film drawn out from the box is brought into close contact with the unwinding prevention layer, thereby preventing the wrap film from unwinding.

  In the wrapping film storage box described in Patent Document 2, a high adhesion surface having high adhesion to the wrap film is formed at both ends in the length direction of the box, and the cut film is adhered to the high adhesion surface. This prevents the film from reversing and prevents the film from slipping at the beginning of cutting.

  Furthermore, in patent document 3, the folding piece etc. which support the both ends of a roll film are provided in the side surface of the longitudinal both ends of a storage box, and it prevents that a roll film inadvertently jumps out of a storage box. That is, when the roll film inadvertently jumps out of the storage box, the film end is prevented from being wound around the roll film side surface.

  On the other hand, in the instruction manual for roll film storage boxes on the market, as a countermeasure when the film edge has already adhered to the roll film, the procedure to find the film edge using cellophane tape, etc. Has been introduced.

Japanese Patent No. 2608617 Japanese Patent No. 2705899 Japanese Utility Model Publication No. 61-43702

  As exemplified in each of the above patent documents, in a conventional roll film storage box, a device for preventing the end of the drawn film from unwinding, a device for preventing the film box from inadvertently jumping out, etc. Many have been proposed. However, when this film edge has already adhered to the roll film side, the means for easily peeling off the film edge is extremely limited, and the above-mentioned cellophane tape must be relied upon. Met.

  In addition, since food film is cut with a saw-like cutter when used, if only part of the film is adhered and peeled off with cellophane tape, only the adhered part will tear from the end of the film. It often ends up. In this case, only a part of the film end that is torn is pulled out, and the remaining film end is in contact with the side surface of the roll, resulting in a delay in circulation. In such a state, it is very difficult to pull out the film end portion to the original state, and it is often the case that the use of the film is given up and discarded as it is.

  Therefore, the means to pull out the film edge that has been wound around the side of the roll film must be extremely troublesome even if adhesive tape is used, and the film edge that anyone can easily use A means of pulling out was desired.

  Therefore, the present invention has been created to solve the above-mentioned problems, and a film end portion drawing method and a drawer in which anyone can easily pull out the film end portion that has already adhered to the side surface of the roll film. The object is to provide a storage box provided with a tool or a drawer.

  In order to achieve the above-mentioned object, the first means in the present invention includes a box body 10 that houses a roll film P wound with a wrap film, and a lid 20 that is connected to the opening of the box body 10. In the method of pulling out the film end P1 in which the film end P1 in close contact with the side surface of the roll film is pulled away from the side surface of the roll film P, the entire length of the long side surface of the roll film P can be brought into contact. An adhesive member 2 to which the roll film P can be attached and detached is bonded to the flat surface portion 1A of the storage box 200 to form an end detection surface 3, and the long side surface of the roll film P taken out from the storage box 200 is detected as an end portion. The film end P1 is pressed so as to be in close contact with the surface 3, the film end P1 is adhered to the end detection surface 3, and then the roll film P is rotated to draw out the film end P1.

  The second means is provided in a storage box 200 having a box body 10 for storing a roll film P wound with a wrap film, and a lid 20 connected to an opening of the box body 10. In the drawer device 100 at the end of the film that separates the film end P1 in close contact with the side surface of the roll film P from the side surface of the roll film P, the drawer 100 can be any of the storage boxes 200 that can contact the entire length of the long side surface of the roll film P. This surface is used as an abutment body 1 and an end detection surface 3 is formed by adhering an adhesive member 2 to which a wrap film is detachably attached to a flat surface portion 1A of the corresponding contact body 1. The long side surface of the roll film P taken out is pressed against the edge detection surface 3 to adhere the film edge P1, and the roll film P is rotated to draw out the film edge P1. Located in.

  The adhesive member 2 of the third means is made of a synthetic resin having adhesiveness that is detachable from the wrap film.

  The pressure-sensitive adhesive member 2 of the fourth means is made of acrylic rubber or soft vinyl chloride, or a synthetic resin containing any part thereof is used.

  5th means WHEREIN: The said contact body 1 makes the top plate 21 which comprises the cover body 20 of the said storage box 200, or makes the side plate 22 or the bottom plate 23 which comprises the said box main body 10 solve the subject. Means for this.

  According to claim 1 of the present invention, the film end P1 is attached to the end detection surface 3 by pressing the long side surface of the roll film P so as to be in close contact with the end detection surface 3, thereby adhering the film end P1 to the end detection surface 3. Can be found very easily. In other words, the conventional idea of searching for the film end P1 from a part of the roll film P has been changed so far, and the reverse of searching for the entire film end P1 at a time by simply rotating the roll film P. The idea has succeeded in pulling out the film end P1 very easily.

  As a result, even if the cellophane tape is not used as before, anyone can easily pull out the film end P1 by simply pressing the roll film P against the end detection surface 3 and rotating it. It became possible. In addition, since the film end portion P1 is pulled out with the entire length of the film end portion P1 adhered to the end portion detection surface 3, the film end portion P1 can be partially peeled off with a cellophane tape or the like. The part was cut off from the surroundings, and there was no inconvenience that it was difficult to repair.

  And even if it is the roll film P in which the film edge part P1 is in the state which closely_contact | adhered unevenly, such as a lap | rotation delay, by pressing the longitudinal side surface of the roll film P in parallel with the edge part detection surface 3, a film edge The part P1 can be searched sequentially. Accordingly, the film end P1 that is delayed in circulation can be easily pulled out sequentially.

  The drawer 100 of the second aspect is provided in the storage box 200 for storing the roll film P, and any surface of the storage box 200 on which the entire length of the longitudinal side surface of the roll film P can contact is contacted body 1. In addition, since the end detection surface 3 is formed by adhering the adhesive member 2 to which the roll film P is detachably attached to the flat surface portion 1A of the contact body 1, the configuration of the drawer 100 itself is extremely high. It becomes a simple configuration. Therefore, the drawer device 100 of the present invention can always be installed near the roll film P. Therefore, it becomes possible to use the drawing tool 100 together with the roll film P anytime and anywhere.

  According to Claims 3 and 4, since the adhesive member 2 is made of a synthetic resin having adhesiveness that is detachable with respect to the wrap film, the film end portion P1 can be detachably attached to the adhesive member 2. Thus, the operation of detecting the film end P1 while pressing the roll film P against the end detection surface 3 is facilitated.

  According to the fifth aspect, since the main surface of the storage box 200 can be used as the contact body 1, the drawer 100 having a very simple configuration can be provided.

It is a perspective view which shows one Example of this invention. (A) to (C) are side views showing an embodiment of the drawing method of the present invention. It is a top view which shows the other edge part detection method of this invention.

  As described above, according to the present invention, the end of the film that has been wound around the side surface of the roll film can be found very easily and can be easily pulled out by anyone.

  An embodiment of the present invention will be described below. The drawing method of the present invention is carried out on a roll film P in which a long belt-like film is wound into a cylindrical shape. That is, it is a method of easily finding out and pulling out the film end P1 in close contact with the side surface of the roll film P. The material and application of the roll film P are not limited, but are particularly effective for pulling out the film end of the roll film P wrapped with a thin film such as a packaging wrap such as a food wrap film or a stretch film (see FIG. 1).

  The drawer method of the present invention uses a storage box 200 that stores a roll film P wound with a wrap film. The storage box 200 includes a box body 10 that stores the roll film P, and a lid 20 that is connected to an opening of the box body 10. In this storage box 200, the end detection surface 3 is formed by adhering the adhesive member 2 to which the roll film P is detachably attached to the flat portion 1A where the entire length of the long side surface of the roll film P can come into contact ( (See FIG. 1). The adhesive member 2 has such an adhesive force that the roll film P adhered to the end detection surface 3 can be reattached on the end detection surface 3.

  Next, the end detection surface 3 is used to find the position of the film end P1 end. That is, holding the roll film P taken out from the storage box 200, the entire length of the longitudinal side surface of the roll film P is pressed against the end detection surface 3 in parallel (see FIG. 2 (a)). Next, the roll film P is rotated little by little in the circumferential direction while pressing the roll film P (see (b) in the figure).

  When this procedure is repeated and the contact surface of the roll film P is sequentially changed, a part or the whole of the film end P1 is detected in a state where it is adhered to the end detection surface 3. For example, when a part of the film end portion P1 is found, the contact position of the roll film P is reattached, and the longitudinal portion of the film end portion P1 is adhered to the end detection surface 3.

  And after sticking the longitudinal part of the film edge part P1 to the edge part detection surface 3, when the roll film P is rotated in the direction which a film opens, the film edge part P1 adhere | attached on the edge part detection surface 3 will be a roll film. It will be in the state pulled out from the P side (refer to Drawing 2 (c)).

  Further, at the time of the detection, the entire longitudinal portion of the film end P1 is often adhered to the end detection surface 3 at a time. In this case, the film end P1 can be pulled out by a one-touch operation by simply rotating the roll film P (see FIG. 2C).

  In a state where the entire length of the film end P1 cannot be bonded to the end detection surface 3 at one time, such as when the film end P1 is cut obliquely, the film end P1 is bonded as long as possible, and the area to be drawn out is wide. It adjusts, re-sticking so that it may become, and finally it enables it to adhere | attach the whole longitudinal direction of the film edge part P1.

  When a part of the film end portion P1 is delayed, the repair work is the most difficult. Even in this case, it can be easily repaired by the following procedure. First, the film end P1 close to each end of the roll film P is detected. For this detection, the entire longitudinal side surface of the roll film P is not brought into contact with the end detection surface 3, but the roll film P is pressed laterally against the end detection surface 3 (see FIG. 3). When the roll film P is rotated in a state where only one longitudinal end of the roll film P is in contact with the end detection surface 3, the film end P1 can be easily detected.

  When each of the film ends P1 at both longitudinal ends of the roll film P is detected in such a procedure, the film end P1 leading out and the film end P1 delayed in rotation are detected separately, The film end portion P1 that is delayed in circulation is pulled out and aligned with the preceding film end portion P1. Thus, the procedure for repairing the film end portion P1 can be appropriately changed according to the state of the film end portion P1.

  The drawer 100 of the present invention is provided in a storage box 200 having a box body 10 that stores a roll film P wound with a wrap film, and a lid 20 that is connected to an opening of the box body 10. . The drawing tool 100 uses any surface of the storage box 200 with which the entire length of the longitudinal side surface of the roll film P can be contacted as the contact body 1, and the roll film P is attached to and detached from the flat portion 1 </ b> A of the contact body 1. A free adhesive member 2 is bonded to form an end detection surface 3 (see FIG. 1). And the longitudinal side surface of the roll film P taken out from the storage box 200 is pressed against the edge part detection surface 3, and the film edge part P1 is adhered. Further, the roll film P is rotated to draw out the film end P1.

  The adhesive member 2 adheres the roll film P to the flat surface portion 1A of the contact body 1 in a detachable manner. Therefore, the adhesive member 2 is used in which the side surface of the roll film P in contact with the end detection surface 3 can be re-attached on the end detection surface 3. That is, the adhesive force of the adhesive member 2 is an adhesive force that allows the roll film P to rotate while the side surface of the roll film P that is in contact with the end detection surface 3 is stuck and the film end portion is stuck. It can be used as the adhesive member 2 of the drawer 100 of the present invention.

  The adhesive member 2 uses a synthetic resin having adhesiveness that is detachable with respect to the wrap film. In particular, a synthetic resin made of acrylic rubber or soft vinyl chloride or containing any part thereof is suitable. For example, a soft vinyl chloride film or sheet is bonded to the flat portion 1A. Alternatively, an acrylic rubber solvent used as a releasable adhesive may be used as the adhesive member 2 and adhered to the flat portion 1A by spray coating or the like.

  Such a pressure-sensitive adhesive member 2 is only one example of the pressure-sensitive adhesive member 2 used in the present invention, and is not limited to a synthetic resin as long as it has an adhesive force that allows the roll film P to be detachably attached. It is also possible to change to.

  Furthermore, it becomes easier to detect the film end P1 as the area to which the adhesive member 2 is bonded increases. However, it is not always necessary to adhere to the entire surface of the flat portion 1A of the contact body 1, and the belt film P may be adhered to a narrow band shape so that the entire length of the long side surface of the roll film P can be adhered. Moreover, since the edge part detection surface 3 adhere | attaches the full length along the longitudinal direction of the film edge part P1, although the adhesion member 2 may adhere | attach the whole surface on the plane part 1A, the adhesion member 2 is many points. It is also possible to bond with a certain interval such as bonding in a shape.

  On the other hand, the drawer 100 formed in the storage box 200 can be formed by adhering the adhesive member 2 to the inner surface or the outer surface of the top plate 21 constituting the lid 20 of the storage box 200. Further, the adhesive member 2 may be formed by adhering to the inner surface or the outer surface of the side plate 22 constituting the box body 10. Further, the adhesive member 2 can be bonded to the outer surface of the bottom plate 23 constituting the box body 10. Among the surfaces that can be joined to the entire longitudinal side surface of the roll film P in the storage box 200, the only side surface that cannot be used as the drawer 100 is the inner surface of the bottom plate 23. That is, since the roll film P is accommodated on the inner side surface of the bottom plate 23, if the adhesive member 2 is bonded to this surface, the pulling operation of the roll film P is hindered.

  In the illustrated example, the top plate 21 of the lid 20 is the contact body 1 and the inner side surface 21A inside the lid 20 is the plane portion 1A (see FIG. 1). Then, the adhesive member 2 is directly attached to the inner surface 21A to form the end detection surface 3, and the lid 20 is used as the drawer 100.

  When the inner surface 21 </ b> A of the top plate 21 is the contact body 1, the drawer 100 can be used when the lid body 20 is opened. Further, since one side edge of the opened lid 20 is continuous with the opening side edge of the box body 10, the box body 10 is attached with the film end portion P 1 adhered to the adhesive member 2 of the contact body 1. The roll film P can be rotated in the direction. In this case, the lid 20 is supported with one hand, and the roll film P held with the other hand is brought into contact with the inner surface 21A.

  Note that the present invention is not limited to the illustrated example, and design changes such as the shape and dimensions of the contact body 1 and the storage box 200, and replacement of the materials of the contact body 1 and the adhesive member 2 are described in the present invention. As long as the gist of the invention is not changed, it can be freely changed.

  According to the present invention, in addition to food wraps, any wrap film such as packaging wrap can be applied to a roll fill wound in a cylindrical shape.
