Description

  The present invention relates to a wrap film used for packaging foods and the like, and more particularly, to a wrap film drawer used for the withdrawal.

  A packaging wrap film used for packaging foods and the like is generally stored in a paper box as a roll of a long film wound around a paper tube. In use, the wrap film is continuously unwound from a roll and cut into a desired length using a cutting blade provided in a paper box.

  However, wrap film has the property of easily adhering to an object to be packaged, and this property is a preferable feature for hermetically wrapping, but the wrap film is locally overlapped, causing wrinkles and twisting, and is difficult to handle. It is also a drawback.

  Therefore, the wrap film is drawn out with a stick-like instrument with an adhesive that can be attached to and detached from the edge of the wrap film (see Patent Document 1). A wrap film drawing tool for pulling out the wrap film by adhering it to the edge of the wrap film stored in the wrap film storage box, the adhesive plate capable of adhering to the wrap film, and the adhesive plate in the longitudinal direction There has been disclosed a wrap film drawing tool comprising a main body portion sandwiched from both sides of a front surface and a back surface so that an edge on a long side extending along a direction protrudes (see Patent Document 2). Also, use a thin strip plate or stick with the same length as the width of the wrap film, but with a little strength. Apply a small amount of adhesive to the two ends of this plate and pull this film out of the storage box. Or, sticking the tip of the film to a stick and pulling it out (see Patent Document 3) or the same width as a wrapping film for food packaging, an adhesive material was attached to one side of a thin rectangular plate, and the wrapping film was placed on the plate Create a gap between the front of the box and the back of the wrap film outlet, push the bellows on the top of the top lid of the box to the front of the box, and shift the top lid with the blade to the gap. A plate is inserted and intimately attached, pulled out and cut in the required amount in a state where it is stretched and wrapped, and the food is packaged, and then the plate is stored again in the gap behind the drawer opening so that it can be used continuously (patent Reference 4) etc. Those of the configuration of the people has been proposed.

JP-A 63-105629 Japanese Patent No. 397537 Japanese Utility Model Publication No. 7-28840 Japanese Patent No. 3146933 JP 2000-73534 A

  However, when the conventional wrap film takeout tool is used, the following problems occur. The wrap film drawing tool needs a certain degree of adhesive force to pull out the wrap film, but it needs to be peeled off from the wrap film after packaging, and therefore the adhesive force may not be too strong. However, it is very difficult to obtain an appropriate adhesive force only by adjusting the physical properties of the adhesive. That is, if the adhesive strength of the adhesive itself is too strong, the wrap film is too strongly adhered and difficult to peel off. Further, there is a drawback that dust adheres gradually to the pressure-sensitive adhesive layer, and the adhesive force to the wrap film is lowered and unsanitary.

  In addition, as in the invention described in Patent Document 1, there is one in which a pressure-sensitive adhesive is attached to the back surface of the drawer main body with a gap, but this lacks smoothness when the wrap film is peeled off, and is messy. Otherwise, the film may be broken. Furthermore, as in the invention described in Patent Document 2, there is one in which an adhesive is attached only to both ends of the back surface of the main body, but in this state, the central portion of the wrap is floated without sticking to the drawer Therefore, the wrap film cannot be pulled out smoothly.

Therefore, the present inventors have intensively studied and found out that an adhesive seal having a micro suction disk structure is used as the adhesive material. This adhesive seal is an adhesive seal in which fine crater-like depressions are formed on the surface of the adhesion layer, and the depressions act like a sucker on the adherend. This can be obtained, for example, by using an acrylic emulsion containing a foaming agent as a raw material, mechanically stirring it to form open cells, applying the raw material to a substrate such as cloth or paper, and drying by heating. (See Patent Document 5).
Another object of the present invention is to provide a wrap film drawing tool that can smoothly pull out a wrap film from a storage box and that can be easily attached to the wrap film and easily peeled off. To do.

For this reason, the wrap film drawing tool of the present invention is formed in a bendable long plate shape, and a part of the wrap film drawing tool is brought into close contact with the drawing side edge of the packaging wrap film that is wound and stored in a storage box. The first feature of the present invention is that it is a drawing tool that pulls out the wrap to a desired length, and a silicon adhesive is applied or a silicon adhesive film is applied to the contact surface with the wrap film. Further, the second characteristic is that the Young's modulus of the contact surface with the wrap form is 1900 to 3500 MPa (Kg / mm ² ). Furthermore, a third feature is that the wrap film drawer is formed integrally with the storage box so as to be separable.

The physical meaning of adhesiveness, Young's modulus (elastic modulus), is a numerical value that represents how much deformation (strictly how difficult it is to deform) when a force is applied to itself.
Typically, the Young's modulus is iron 21000 MPa (Kg / mm ² ), aluminum 7000 MPa (Kg / mm ² ), polyethylene 76 MPa (Kg / mm ² ), rubber 0.15 MPa (Kg / mm ² ). Those having adhesiveness have a small Young's modulus, and there is no adhesiveness unless the Young's modulus is 0.1 Kg / mm ² (10 7th power dyn / cm ² ) or less.

It is a perspective view which shows the example which formed the storage box and the wrap film extraction tool integrally.

Hereinafter, embodiments of the present invention will be described in detail based on examples shown in the drawings.
As shown in FIG.1 and FIG.2, the wrapping film storage box 2 of this invention has the cutting blade 4 attached to the front-end | tip of the folding lid 2a. The attachment position of the cutting blade 4 is not particularly limited as long as the wrap film 3 is pulled out from the storage box 2 and can be cut. However, generally, when the wrap film 3 is cut, the wrap film 3 is sandwiched between the front plate 2b of the storage box 2 and the folding lid 2a overlapping the front plate 2b, and the folding lid 2a is pressed from the outside. The cutting specification is preferably employed.

  The wrap film drawer 1 made of paper material of the same quality as the storage box 2 is formed in a long plate shape that can be bent in the short direction of the storage box 2. The material of the wrap film drawer 1 is not limited to paper, but may be plastic or the like as long as it is an elastic material. Become.

Then, a slightly adhesive film 5 made of a polyester film coated with a silicone adhesive is attached to the contact surface of the wrap film drawer 1 with the wrap film 3. In this example, REPOP (trade name: manufactured by Lintec Corporation) product numbers RE503S and RE505S were used. This REPOP (trade name) is commercially available with a double-sided polylaminated high-quality paper as a release mount on a surface substrate of a 50 μm white foamed polyester film or transparent polyester film having a slightly adhesive silicon layer. The adhesive strength after 24 hours of REPOP (trade name) is 50 mN / 25 mm when the adherend is glass, 40 mN / 25 mm when polycarbonate or acrylic is used (the test conditions are a peeling speed of 300 mm / min and a peeling angle of 180 ° peel). It was done by angle peel measurement.)

In order to quantitatively know the adhesiveness of REPOP (trade name), a tensile test and a shear force test were conducted. The results are shown in Tables 1 and 2. In the table, MD and CD indicate the direction of the paper perforation, MD indicates the direction along the perforation (vertical eye), and CD indicates the direction perpendicular to the eye (horizontal eye).
(1) Tensile (measurement items: yield strength, elongation, strength at break, elongation at break, Young's modulus)
(2) Shear force (The shear force of a single sample was measured at a tensile speed of 50 mm / min.)

As can be seen from Tables 1 and 2, when the adhesive strength of the slightly adhesive film 5 is quantified by its Young's modulus, a range of 1900 to 1500 MPa (Kg / mm ² ) is preferable in consideration of errors due to the measurement atmosphere. I understand. The adhesive film 5 can be used many times in a clean state because it can be easily restored by washing with water and drying, even if the adhesive strength is reduced due to adhesion of dust or foreign matter. In addition, it may replace with sticking of the slightly adhesive film 5, and may form by apply | coating slightly adhesive silicon so that it may become the same Young's modulus. Moreover, you may give a micro suction cup process so that it may become the same Young's modulus.

  The wrap film 3 is a food packaging wrap film generally marketed in the form of a wound roll, and is made of a main material such as polyvinylidene chloride or polyethylene. This type of wrapping film has the property of adhering to or closely adhering to the packaged item, and is suitable for sealing and storing the packaged item such as food. Widely used as an industrial food packaging material.

  As shown in FIG. 2, the wrap film drawing tool 1 is formed such that a close contact surface (folded piece) can be folded by pressing, the fold line 1 b is lined, and the folded piece 1 a. A close contact surface is formed on the surface of. A slight adhesive film 5 is attached to the adhesion surface, whereby the surfaces of the wrap film 3 and the slightly adhesive film 5 are appropriately adhered to each other, and have good adhesiveness when the wrap film 3 is taken out, and is smooth. The wrap film 3 after wrapping the article to be packaged can be easily pulled off from the drawer 1.

  That is, the sticking surface is provided with a slightly sticky film 5 having a slightly sticky silicon layer, so that the drawer 1 is in close contact with the wrap film 3 and a sufficient adhesive force is given to the drawer. Does not adhere too strongly. In addition, it is possible to eliminate the disadvantage that a large amount of dust adheres to the drawer 1 and the wrap film 3 is deteriorated in retention or unsanitary. Furthermore, the lapping film 3 after lapping can be easily peeled off from the drawer 1. Moreover, especially the drawer tool 1 can adhere | attach both right-and-left both ends reliably, and can tension | pulling the pulled out wrap.

  Hereinafter, a method for wrapping dishes and the like by pulling out the wrap film 3 stored in the film storage box 2 using the wrap film drawing tool 1 will be described.

  First, as shown in FIG. 3, one surface of the wrap film drawing tool 1 is attached to the edge of the wrap film 3 on the pulling side. Next, as shown in FIGS. 4 and 5, the wrap film drawing tool 1 is pulled, the wrap film 3 is pulled out by a desired length, the dish is covered, and then the cutting blade attached to the storage box 2 is attached. Cut by 4. Finally, the wrapping film 3 is adjusted to match the shape of the dish, and lapping is completed.

  Further, as shown in FIG. 6, the wrap film drawer 1 can be prevented from being lost and can be stored in the storage place if it is adhered again to the starting end of the roll after use and is sandwiched between the folding lids 2a of the storage box 2 as it is. . In addition, it is possible to prevent the draw end of the wrap from being wound around the roll body, and it is in a state of being given a clue to be drawn out when it is used next time, which is clean and convenient. It should be noted that the wrap film drawing tool 1 can be previously placed alone in the storage box 2 together with the wrap film 3. In addition, as shown in FIG. 7, when the wrap film drawing tool 1 can be separated from the storage box 2 by the perforation line 7 and the like through the separation margin and formed integrally, the manufacturing cost can be reduced.

  According to the present invention, the film and the lap contact surface adhere to each other, but do not adhere strongly, and therefore can be peeled off very easily. In addition, the surface of the wrap film drawer that is in close contact with the wrap is formed with a slightly adhesive silicon layer, so that it adheres well when the wrap film is taken out, and the entire wrap end corner is securely held without dripping. can do. As a result, even if the drawer width is short, the wrap can be cut reliably, and the entire drawn wrap can be evenly pinched. For this reason, it becomes easy to wrap and the sharpness by a cutting blade also becomes favorable. Moreover, since the wrap and the drawing tool are not strongly bonded, but the surfaces are in close contact with each other, the wrap film after lapping can be easily peeled off from the drawing tool.

For this reason, the wrap film draw-out tool of the present invention is formed into a long plate shape, and a part of the wrap film draw-out tool is closely attached to the draw-out side edge of the packaging wrap film stored in a roll shape in the storage box. a pull-out tool to draw the lap lengths, the take-out device is substantially the same width and in the transverse direction with respect to substantially packaging wrap film to draw and can trough folding angle exhibiting an arcuate storage box for is formed to a length, with attaching a or slightly adhesive film coating the slightly adhesive adhesive to the contact surface of the pull-out device side of the wrap film, 24 hours after adhesion of the contact surface is, the adherence substance that If is the glass 50 mN / 25 mm, when the polycarbonate or acrylic 40 m N / 25 mm (test conditions, peeling rate 300 mm / min, peeling angle 180 ° peel variable angle peel measurement) is And a feature. The second feature is that the wrap film drawer is formed integrally with the storage box so as to be separable.

The physical meaning of adhesiveness, Young's modulus (elastic modulus), is a numerical value that represents how much deformation (strictly how difficult it is to deform) when a force is applied to itself. Representative Young's modulus, iron ^{2100 0 MPa (N / mm 2} ), aluminum ^{7000 0 MPa (N / mm 2} ), polyethylene 6MPa (N / ^mm 2), rubber ^{1.5 MPa (N / mm 2)} . Those having adhesiveness have small Young's modulus, and there is no adhesiveness unless the Young's modulus is 1 dyn (1 × 10 ⁻⁵ / N / mm ² ) or less.

Then, the contact surface between the wrapping film 3 of wrapping film pull-out device 1 is formed by attaching a weak adhesive film 5 made of a polyester film silicon over down adhesive has been applied. In this example, REPOP (trade name: manufactured by Lintec Corporation), product number RE503S and 505S was used. The adhesive strength after 24 hours of this REPOP (trade name) is 50 mN / 25 mm when the adherend is glass, 40 mN / 25 mm when polycarbonate or acrylic is used (the test conditions are a peeling speed of 300 mm / min, a peeling angle of 180 ° peel). This was done by measuring the variable angle peel.)

Even if the adhesive force is reduced due to adhesion of dust or foreign matter, the slightly adhesive film 5 can be easily restored by simply washing it with water and drying it, so that it can be used many times in a clean state. It is also intended to have a similar Young's modulus in place of sticking of the microporous adhesive film 5 is formed by applying a weak adhesive silicone over emissions directly. Moreover, you may give a micro suction cup process so that it may become the same Young's modulus.

That is, by providing by sticking a slightly adhesive film 5 having a slightly adhesive silicone over down layer to the contact surface, the extraction device 1 is in close contact with the wrap film 3, although sufficient adhesion is imparted to the drawer, wrap The film 3 does not adhere too strongly. In addition, it is possible to eliminate the disadvantage that a large amount of dust adheres to the drawer 1 and the wrap film 3 is deteriorated in retention or unsanitary. Furthermore, the wrap film 3 after lapping can be easily peeled off from the drawer 1. Further, the pull-out device 1, as shown in FIG. 3, the wrap film pull-out device 1, with respect to the lateral direction of the receiving box 2 substantially valley fold possible and packaging Rappufu Irumu to draw the angle exhibiting the arc Since it is formed to have substantially the same length as the horizontal width, the handleability is improved, particularly the left and right ends can be securely adhered, and the drawn wrap can be pinned.

According to the present invention, the film and the lap contact surface adhere to each other, but do not adhere strongly, and therefore can be peeled off very easily. Further, the contact surface between the lap wrap film pull-out device, by forming a weak adhesive silicone over down layer, is satisfactorily adhesive upon removal of the wrap film, reliably throughout without drips both corners of the wrap end Adhesion can be retained. As a result, even if the drawer width is short, the wrap can be reliably cut, and the entire drawn wrap can be evenly pinched. For this reason, it becomes easy to wrap and the sharpness by a cutting blade also becomes favorable. Moreover, since the wrap and the drawing tool are not strongly bonded, but the surfaces are in close contact with each other, the wrap film after lapping can be easily peeled off from the drawing tool.
