Description

  The present invention relates to a chuck made of a resin male tape and female tape, and a bag using the chuck.

  Resin chucks, also known as “poly fasteners” or “poly chucks”, consist of a resin male tape with a male strip on the tape substrate and a resin female tape with a female strip on the tape substrate. The male streak is fitted and detached from the female streak and sealed and opened. This resin chuck is easy to seal and open, and also has good air tightness or liquid tightness in the sealed state. Therefore, the resin chuck is attached to the mouth of a bag body of a resin bag, for example. It is widely used as a sealing member that realizes the hermeticity.

  As seen in, for example, Patent Document 1, a resin-made chuck elastically deforms the hook-shaped wall with respect to female strips (female protrusions) of a female tape composed of a pair of hook-shaped walls (hook portions) that are elastically deformed. It is the structure which inserts the head of the male strip (male projection) of a male tape, doing it. The resin-made chuck of Patent Document 1 proposes to provide an elastic adhesive material at the bottom of the female streak in order to firmly engage the head of the male streak with the saddle-shaped wall of the female streak. The elastic adhesive material is extruded and supplied when the female strip is extruded, or is applied to the already formed female strip later. This elastic adhesive material is composed of a synthetic rubber-based polymer as a main component and a tackifier.

JP 2006-102068 A ([0019], [0022], [0034], FIG. 2 and FIG. 3)

  The resin chuck is attached to the mouth of the bag body made of a resin film and constitutes a highly sealed bag. Thereby, the said bag isolate | separates the foodstuff accommodated, for example from the external world, and enables long-term preservation | save after that it does not mix various germs from the external world after that. However, when food is stored in the bag, there is no denying that there is a possibility that various germs are mixed. In this case, various germs are mixed when the germs attached to the mouth of the bag body touched when the food is stored in the bag touch the food. From now on, the chuck needs to be kept as clean as possible.

  Moreover, if the bag is left in the state where the chuck is opened, there is a risk that germs and the like may enter the bag from the mouth of the bag body, and the conventional chuck has no means to prevent such germs from entering. . In addition, the conventional chuck merely seals the opening of the bag body, does not have any other function, and has little added value. Therefore, in order to keep the mouth of the bag body clean and prevent the invasion of germs even if the mouth of the bag body is open, the resin chuck has an added value not found in conventional chucks. Was examined.

  As a result of the study, it consists of a resin male tape with a male strip provided on the tape base material and a resin female tape with a female strip provided on the tape base material. In the resin-made chuck that seals and opens, the functional agent that exerts a specific action on the surrounding environment is any of the tape material of the male tape, the male strip, the tape substrate of the female tape, and the resin material that forms the female strip. We have developed a chuck that mixes all or all of them. In the present invention, the chuck is attached to the mouth of a bag body made of a resin film to form a bag, or the chuck is attached to the mouth of a bag body made of nonwoven fabric to constitute a bag.

  As for the resin material which forms the male tape and female tape used for this invention, it is desirable to mix a synthetic resin elastomer. The synthetic resin elastomer is not particularly limited as long as it is an elastomer compatible with the resin material forming the male tape or the female tape. For example, when the resin material forming the male tape or the female tape is a polyolefin resin material, a polyolefin elastomer is preferable. Thus, the synthetic resin elastomer is mixed with the resin material forming the male tape and the female tape, so that the male tape and the female tape, in particular the male strip and the female strip, become flexible and can be easily attached and detached. The adhesion between the strips and female strips is also improved.

  The chuck according to the present invention provides a functional material such as an insect repellent, an acaricide, an antibacterial agent or a fragrance to the resin material mixed with a resin material or a synthetic resin elastomer for forming a male tape or a female tape. It is more preferable to mix 1 type or 2 types or more. Each of the functional agents exerts a specific action on the surrounding environment, for example, if the functional agent is an insect repellent, exhibits an insect repellent action, and imparts an insect repellent effect to the chuck and the mouth of the bag to which the chuck is attached. Thereby, the bag to which the chuck of the present invention is attached can repel pests from the chuck and keep the chuck clean, and can also prevent pests from entering the bag. In addition, if the functional agent is an anti-mite agent, it exhibits an anti-mite effect, if the functional agent is an anti-bacterial agent, it exhibits an anti-bacterial effect, and if the functional agent is a fragrance, it exerts an aroma action. Additional values such as a tick-proof effect, antibacterial effect or aroma effect can be imparted to the chuck and the bag.

  If the functional agent is in a solid or powder form, the chuck itself has the specific action and effect of the functional agent, and the range of the specific action and effect is narrow. However, if the functional agent is liquid, the functional agent is gradually released from the resin material, for example, by appropriately contacting the article or hand stored in the bag, or by evaporating the functional agent into the outside air, the specific action and The effect can be extended widely. For example, when the functional agent is an insect repellent solution and a zipper mixed with male strips of male tape and female strips is attached to the mouth of the bag body made of resin film to form a bag, gradually from male strips and female strips. The released insect repellent liquid evaporates to the outside air, forming a region where the insect repellent action is exerted in the periphery including the mouth of the bag. Thereby, a pest does not approach the periphery including the mouth of the bag body, and even if the mouth of the bag body is opened, the pest does not easily enter the bag through the mouth of the bag body.

  The functional agent is mixed with the tape base material and the male strip or female strip if the male tape or female tape, for example, is configured to integrally form the tape base and male strip or female strip, respectively. And the male strip or female strip may be mixed with at least the male strip or female strip. The male tape or female tape including the male strip or the female strip is formed of a polypropylene resin, a polyethylene resin, a polystyrene resin, or the like, similarly to a conventionally known chuck. In this case, a solid or powdery functional agent can be directly mixed with the resin material, but a liquid functional agent is difficult to mix with the resin material. Therefore, in the case of a liquid functional agent, a capsule in which the functional agent is wrapped with another resin material may be mixed with the resin material forming the chuck.

  According to the present invention, the adhesiveness of the mouth of the bag body is increased, the inside of the bag body is kept clean, and even if the mouth of the bag body is open, the presence of the functional material prevents the invasion of pests, etc. It becomes a resin chuck with added value. When the chuck comprising the tape base material of the present invention is used, the heat-sealing property of the tape to the bag body resin is enhanced, and the trouble of peeling from the bag body is eliminated. Therefore, it is possible to provide a chuck that can be applied to any bag made of resin or non-woven fabric.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a bag 3 using the chuck 1 of the present invention, FIG. 2 is a cross-sectional view of the chuck 1 used for the bag 3 of this example, and FIG. FIG. As shown in FIGS. 1 and 2, the bag 3 of this example has a tape base 111 of the male tape 11 of the chuck 1 of the present invention and a tape of the female tape 12 with respect to the opening 32 of the non-woven bag 31. With a configuration in which the base material 121 is heat-sealed or ultrasonically welded in an opposing relationship and attached, the appearance is the same as that of a conventionally known similar bag. The same applies when the bag 31 is made of a resin film.

  The chuck 1 has a configuration in which a male strip 112 provided on a tape base 111 of a male tape 11 is fitted to and detached from a female strip 122 provided on a tape base 121 of a female tape 12 to be sealed and opened. Thus, in appearance, it is not different from a conventionally known same-type bag (for example, see Patent Document 1). The characteristics of the present invention will be described with reference to this example. The base tape constituting the male tape 11 and the female tape 12 and the male strip 112 and the female strip 122 are mixed with a synthetic resin elastomer or liquid, respectively. The functional agent 2 is encapsulated and mixed.

  As shown in FIG. 3, the encapsulated liquid functional agent 2 is gradually released over a long period of time, evaporates, and exhibits a specific action widely in the surrounding environment. The functional agent 2 that is gradually released from the chuck 1 is diffused to the periphery by the engagement and disengagement of the male strip 112 and the female strip 122 of the chuck 1, and insect repellent in the surrounding environment around the chuck 1, particularly in the bag body 31. Bring effect. Further, the article stored in the bag body 31 is brought into contact with the article stored in the bag body 31 through the opened chuck 1, and the article can be protected against insects, antibacterials, mites, and the like. Next, the present invention will be described more specifically with reference to examples.

<Example 1, comparative example 1>
According to the present invention, a bag in which a chuck mixed with an antibacterial agent is attached to the mouth of the bag body in Example 1, a bag in which a normal chuck not mixed with the antibacterial agent is attached to the mouth of the bag body as Comparative Example 1, The antibacterial activity of was compared. In Example 1, a PP chuck manufactured by C-Isan Plus Co., Ltd. is used as a raw material resin, and the antibacterial agent ApizzaS AP-OK is kneaded in 1% by weight and molded again into a male tape and a female tape. Antibacterial activity was confirmed for the bag in which the chuck was attached to the mouth of a laminated plain film bag of OPP 30 μm / CPP 30 μm.

  For the bag of Comparative Example 1, a commercially available liquid beef stew with a zipper bag was purchased. This bag is a laminate of OPP 30 μm / VMCP 25 μm / L-LDPE 30 μm, in which 320 g of contents are enclosed in a 14 cm × 22 cm chuck bag. Open this bag and remove the contents from the bag into a soup dish, wipe the contents adhering to the chuck part with a tissue, and close the rest for the comparative example. did. The bag of Example 1 was also filled with beef stew from the soup plate, the contents adhering to the chuck portion were wiped with a tissue in the same procedure as in the comparative example, and then the chuck was closed. These chuck bags were left in a normal environment at a room temperature of 17 ° C to 23 ° C.

  By this method, antibacterial tests were conducted on two types of specimens, an antibacterial chuck and a normal chuck. In Comparative Example 1 of the normal chuck product, a blue mold-like product is generated from the stew residue slightly adhered to the chuck on the 6th day, and it spreads sideways along the chuck on the 8th day, and a strange odor is detected. did it. There was no change in the stew in the chuck bag.

  On the other hand, the sample using the antibacterial chuck of Example 1 had no change on day 6 and day 8, and the difference between the two products became clear.

  In food products, bags that use chucks are eaten and eaten in several batches, and the rest are eaten at a later time. Even when the chuck is closed, it is easy to generate mold and spoilage on the part that comes into contact with the outside air. However, it was proved that the use of a chuck kneaded with an antibacterial agent was extremely hygienic.

<Example 2>
4% of a cedarwood oil resin (trade name: Slope CW) that smells of a forest bath was kneaded into an L-LDPE chuck manufactured by C-Isan Plus Co., Ltd. in the same manner as in Example 1 and molded into a chuck again. Using this chuck, we made a PET / VMPET / L-LDPE laminated film chuck bag.

  Put small items such as handkerchiefs in this prototype bag, leave them for 2 days, open the chuck, and take out the handkerchief. And enjoyed the atmosphere. The same effect was confirmed on the fifth, tenth and twentieth days.

  Although the cost did not increase so much when kneading the fragrance into the chuck, it was confirmed that the released fragrance accumulated in the barrier bag and exhibited the effect. Moreover, the perfume transpiration is triggered by the influence of deformation of the chuck resin or the occurrence of friction each time the opening / closing operation is performed, and the effect is further enhanced. The use of this type of bag with a chuck can be expected to be used for gift bags, accessory storage bags for accessories, and underwear bags for travel.

<Example 3>
The bag 3 of this example is made of nylon (NY) / low density polyethylene (LDPE) laminate film on the front and nylon nonwoven fabric (NY-NWF) / low density polyethylene (LDPE) laminate film on the back. Was used. To the mouth 32 of the bag 31, as a tape base material for male and female tapes of the chuck, a 54% emulsion of piperonyl butoxide, which is an insecticide such as weevil, is added to a polyethylene elastomer (L-LDPE) with a very low density against LDPE. A zipper molded using a 20% kneaded insecticidal functional resin kneaded with 5% was ultrasonically fused to obtain a bag with a polychuck of the present invention. As a comparative example, a bag containing no insect repellent functional resin was used to open and close the chuck while being stored under high temperature and high humidity from summer to June, and there was no occurrence of weevil in the bag of the present invention. On the other hand, the weevil was found in the rice.

<Example 4>
Male tape is a low density polyethylene (LDPE) that forms male and female tapes of the chuck and 20% of the ultra low density polyethylene elastomer (L-LDPE) used in Example 3 as a synthetic resin elastomer. And female tape, in particular male strips and female strips, become flexible and easy to attach and detach, and the adhesion between the male strips and female strips is also improved. The effect of improving adhesion is recognized by flexible synthetic resin elastomers, and it is recognized that the oily substance of the functional material also functions to impart flexibility to the chuck. It was also observed in the hand tensile qualitative test.
