Description

  The present invention relates to a roll film in which a food wrap film or the like is wound in a cylindrical shape, and a film end drawing method and a drawing tool or a drawing tool capable of easily pulling out a film edge closely attached to a side surface of the roll film. It is related with the storage box provided.

  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.

Moreover, the method etc. which affix a cloth-made gum tape on the longitudinal direction of a roll film, and peel off are also disclosed as information on the internet. According to this method, the cloth-made gum tape is applied along the longitudinal side surface of the roll film, the end of the gum tape is divided into three equal parts along the width direction, and the center part of the three-divided ends along the longitudinal direction. When the film is forcibly cut off, the film adhered to the gum tape is also cut off at the same time to form a new film edge.
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, the means for easily peeling off the film edge when the film edge has already been in close contact with the roll film side is very limited, relying on cellophane tape as described above, cloth gum tape, etc. It was unavoidable. However, since the peeling means using the cloth gum tape is a means for forcibly tearing the bonded cloth gum tape along the longitudinal direction, it requires a fingertip force, a knack, etc., and anyone can easily execute it. It was not a means.

  On the other hand, this type of roll film has not only the effect of static electricity but also the so-called van der Worth force and the slight adhesive force on the film surface that try to attract each other when the molecules of the substance approach each other. And it is known that a film edge part closely_contact | adheres to a roll film side surface. 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 is torn from the end of the film. It often ends up. In this case, only a part of the film end portion that is torn is pulled out, and the remaining film end portion is in contact with the roll side surface, 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 or cloth gum tape is used, and anyone can easily use it. There has been a desire for a means for pulling out the end of the film.

  Therefore, the present invention was created to solve the above-mentioned problems, and anyone can easily find out and pull out the film end that has already been in close contact with the side surface of the roll film. And it aims at providing the storage box provided with the drawing tool or the drawing tool.

  In order to achieve the above-mentioned object, the first means in the present invention uses a roll film P in which a long belt-like film is wound into a cylindrical shape, and the film end P1 in close contact with the side surface of the roll film is used as the roll. In the drawing method of the film end portion to be separated from the side surface of the film P, the pressure sensitive adhesive 2 to which the roll film P is detachably adhered is attached to the flat surface portion 1A in a range where the entire length of the long side surface of the roll film P can contact. The end detection surface 3 is formed, the long side surface of the roll film P is pressed so as to be in close contact with the end detection surface 3, the film end P1 is adhered to the end detection surface 3, and then the roll film P is rotated. The film end P1 is pulled out.

  The second means is used for a roll film P in which a long belt-like film is wound into a cylindrical shape, and the film end P1 that is in close contact with the side surface of the roll film P is pulled away from the side of the roll film P. In the tool 100, the pulling tool 100 is configured such that the roll film P is detachably attached to the abutting body 1 having a flat surface portion 1 </ b> A with which the entire length of the long side surface of the roll film P can abut. It is composed of an end detection surface 3 formed by adhering the adhesive 2 to be bonded, and presses the end detection surface 3 and the side surface of the roll film P in parallel to bond the film end P1; This is a drawing tool that rotates the roll film P to draw out the film end P1.

  The third means is used for a roll film P in which a long belt-like film is wound into a cylindrical shape, and includes a drawer 100 that pulls the film end P1 in close contact with the side surface of the roll film P away from the side surface of the roll film P. In the roll film storage box 200, the storage box 200 includes a box body 10 that stores the roll film P, and a lid body 20 that is swingably provided at an opening along the longitudinal direction of the box body 10. The drawing tool 100 uses the top plate 21 of the lid 20 as the contact body 1 of the drawing tool 100, and attaches the adhesive 2 to the inner side surface of the corresponding contacting body 1 so as to draw the drawer. The end detection surface 3 of the tool 100 is in a storage box configured to rotate while pressing the entire length of the longitudinal side surface of the roll film P in parallel with the end detection surface 3.

  According to the first aspect 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. Can be found very easily. That is, the idea of searching for the whole from a part of the film end P1 is changed so far, and the roll film P is simply rotated by the reverse idea of searching for the film end P1 from the entire long side surface of the roll film P. The film end P1 was successfully pulled out with a simple operation.

  As a result, 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 without using the conventional cellophane tape or cloth gum tape. Became possible. In addition, since the film end P1 is pulled out with the entire length of the film end P1 adhered to the end detection surface 3, a part of the film end P1 is removed as when partially peeled off with a cellophane tape or the like. Has been removed from the surroundings, and there is no longer any inconvenience that makes repair difficult.

  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.

  In the drawer 100 of the second aspect, the roll film P is detachably bonded to the abutment body 1 having the flat surface portion 1A on which the entire length of the longitudinal side surface of the roll film P can abut, and the flat surface portion 1A of the corresponding contact body 1. Since it is comprised with the edge part detection surface 3 formed by adhering the adhesive 2 made, it becomes a very simple structure as drawer 100 itself. Therefore, as long as it has the plane part 1A which can press the full length of the longitudinal side surface of the roll film P in parallel with the edge part detection surface 3 of the contact body 1, any member will be sufficient as the drawer 100 of this invention. It becomes possible to use as. As a result, the drawer 100 having a free shape can be provided according to the use of the roll film P.

  The storage box 200 according to claim 3 includes a box body 10 that stores the roll film P, and a lid body 20 that is swingably provided at an opening along the longitudinal direction of the box body 10. Since the end detection surface 3 is provided on the inner side surface 21A of the plate 21, the adhesive 2 on the end detection surface 3 when not in use does not interfere with normal use of the roll film P and touches the user's eyes. There is nothing. Furthermore, dust can be prevented from adhering to the end detection surface 3 when not in use and can be used cleanly.

  As described above, according to the present invention, it is possible to find various industrially useful effects such as finding out the film end portion wound around the side surface of the roll film very easily and easily pulling out the film end. .

  In the best mode of the present invention, a contact body 1 having a flat surface portion 1A in which the longitudinal side surfaces of the roll film P can be contacted in parallel, and an adhesive 2 is attached to the surface of the flat surface portion 1A of the corresponding contact body 1. The formed end detection surface 3 constitutes a film end drawing tool 100. At this time, the drawer 100 is assumed to be installed in a box body 10 that stores the roll film P, and a lid 20 that is swingably provided in an opening along the longitudinal direction of the box body 10. The top plate 21 of the lid 20 is used as the abutment body 1, the inner side surface 21A of the top plate 21 is used as the flat surface portion 1A, and the adhesive 2 is attached to the surface of the inner side surface 21A to detect the end detection surface. Let 3 be a drawer 100 on which 3 is formed. Then, the long side surface of the roll film P is pressed in parallel with the end detection surface 3 of the contact body 1 to adhere the film end P1, and the roll film P is rotated in the direction in which the film is opened to thereby remove the film end P1. The original purpose is achieved by the storage box 200 provided to be pulled out.

  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).

  In the drawing method of the present invention, first, the end detection surface 3 is formed by attaching the adhesive 2 to the flat surface portion 1A of an arbitrary member in which the entire length of the longitudinal side surface of the roll film P is freely contactable (see FIG. 1). . For the pressure-sensitive adhesive 2, it is preferable to use the pressure-sensitive adhesive 2 having a relatively weak adhesive force such 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, the entire length of the longitudinal side surface of the roll film P is pressed in parallel with the end detection surface 3 (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. Then, when a part of film edge part P1 is found, the contact position of the roll film P is reapplied and the longitudinal part of the film edge part P1 is adhere | attached on the edge part detection surface 3. FIG.

  And after bonding 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 in which the film opens, the film edge part P1 left on the edge part detection surface 3 becomes the roll film P. It will be in the state pulled out from the side (refer to FIG. 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 P1 is delayed, it was the most difficult repair work. 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 drawing tool 100 of the present invention includes a contact body 1 and an end detection surface 3 (see FIG. 1). That is, the contact body 1 uses a member having a flat portion 1A that allows the long side surface of the roll film P to contact. Further, an adhesive 2 is attached to the flat surface portion 1 </ b> A of the contact body 1 to form the end detection surface 3.

  The drawer 100 of the present invention is configured as an independent drawer 100 (see FIG. 4), a part of the storage box 200 for storing the roll film P (see FIG. 1), and a part of the table top plate. Or the like can be formed as the drawer 100.

  In the case of configuring the independent drawing tool 100, a member having the flat surface portion 1A that allows the full length of the side surface of the roll film P to be abutted becomes a target of the abutting body 1. Therefore, an article having an arbitrary shape having the flat portion 1A can be used as the contact body 1 (see FIG. 4). The material of the contact body 1 can also be arbitrarily selected, and any material that can press the side surface of the roll film P, such as paper, synthetic resin, metal, leather, and wood, may be used.

  In order to use the drawing tool 100, the contact body 1 is placed on a table or the like and pressed with the roll film P, or the roll film P is placed on the table or the like, and the drawing tool 100 is pressed from above. Use is also possible. Further, since the surface other than the flat portion 1A of the contact body 1 does not have to be flat, an appropriate process such as a handle 4 for operating the contact body 1 or an arbitrary base for fixing the contact body 1 is performed. It is also possible to apply (see FIG. 4).

  Further, when the independent drawer 100 is configured, an adhesive material such as a synthetic resin material can be used for the contact body 1. In this case, the pressure-sensitive adhesive 2 does not adhere to the flat portion 1A later, and the property of the contact body 1 itself is used as the pressure-sensitive adhesive 2.

  The flat surface portion 1 </ b> A of the contact body 1 is formed as a surface on which the entire length of the long side surface of the roll film P contacts. Therefore, it may be a flat portion 1A that is curved along the circumference of the roll film P (see FIG. 5). Moreover, the contact body 1 which presses so that a flexible plate-shaped material and a sheet | seat material may be used as the contact body 1 and the side surface of the roll film P may be wrapped may be sufficient (refer FIG. 6). As described above, the independent drawing tool 100 may be any member in which the flat portion 1A of the contact body 1 has a surface with which the entire length of the longitudinal side surface of the roll film P contacts, and the shape, material, The design of the hardness can be freely changed.

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

  For example, it can be used as the pressure-sensitive adhesive 2 by adhering a liquid, powder or the like to the adhesive surface of a cellophane tape or gum tape to weaken the adhesive force. Further, according to experiments, it has been clarified that an elastomer solvent type adhesive can be used as the adhesive 2 as the adhesive 2. In this experiment, even when an appropriate amount of this elastomer solvent-type adhesive is applied to the non-printing surface of the paper constituting the lid 20 of the storage box 200 to form the end detection surface 3, it is repeatedly used as the adhesive 2. It has been confirmed that this is possible.

  Such a pressure-sensitive adhesive 2 is only one embodiment of the pressure-sensitive adhesive 2 used in the present invention, and other adhesives or pressure-sensitive adhesives can be used as long as they have an adhesive force that allows the roll film P to be detachably attached. It is possible to change to an agent or the like.

  Furthermore, it becomes easier to detect the film end P1 as the area to which the adhesive 2 is attached becomes wider. However, it is not always necessary to adhere to the entire surface of the flat portion 1A of the abutting body 1, and it may be attached to a narrow band shape so that the entire length of the longitudinal 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 adhesive 2 may be apply | coated to the whole surface on the plane part 1A, the adhesive 2 is many points. It is also possible to adhere at a certain interval such as adhering in a shape.

  Further, the adhesive 2 is attached by means such as brushing, printing, spraying, etc., for directly attaching the adhesive 2 to the flat surface portion 1A of the contact body 1. In addition, a contact body 1 having a pressure sensitive adhesive 2 attached to a flat surface portion 1A such as a sheet or a film is separately formed, and this contact body 1 is used by being bonded to a flat surface portion 1A of another contact body 1 or the like. It is also possible.

  As an example of the storage box of the present invention, an embodiment will be described in which a part of the storage box 200 that stores the roll film P is used as the drawer 100 (see FIG. 1). The storage box 200 includes a box main body 10 that stores the roll film P, and a lid 20 that is swingably provided at an opening along the longitudinal direction of the box main body 10.

  In this case, the contact body 1 uses any side plate of the storage box 200 that contacts the longitudinal side surface of the roll film P as the contact body 1. That is, it can be selected from the top plate 21 or the side plate 22 or the bottom plate 23 of the storage box 200, or a combination thereof. Then, an adhesive 2 to which the roll film P is detachably attached is attached to the flat portion 1A of the contact body 1 to form the end detection surface 3. Further, an adhesive 2 is attached to an independent sheet-like or film-like flat part 1A to form a drawer 100, and this drawer 100 is attached to the flat part 1A of the storage box 200 to detect the end detection surface 3. It is also possible to form

  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 2 is directly attached to the inner side 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 in a state where the film end P 1 is adhered to the adhesive 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.

  As another embodiment, the bottom plate 23 can be the contact body 1 and the outer surface of the contact body 1 can be the end detection surface 3 (see FIG. 7). In this case, since the adhesive 2 is attached to the outside of the box body 10, release paper 5 or the like covering the end detection surface 3 when not in use may be attached to the end detection surface 3.

  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 2 are included in the present invention. As long as the gist of the invention is not changed, it can be freely changed.
