Abstract

[PROBLEMS] To prevent insect pests that may enter a bag during storage of rice cereals during bagging or after bagging, and at the same time suppress the occurrence of mold and the like, and keep the freshness of stored items. Provide storage bags.
A double-folded non-woven tape is sandwiched between at least both edges of both ends of a base film 10 that is laminated, and air passages 12 communicating with the outside air are secured at a plurality of locations on both edges, and the edges are formed. In the storage bag formed by heat sealing, the nonwoven fabric tape is impregnated with a solution of chili or wasabi, and the bent portion 11a of the nonwoven fabric tape is protruded into the storage bag.

Description

  The present invention prevents insect pests from entering the bag containing cereals, suppresses the occurrence of mold, etc., is effective in maintaining the freshness of cereals, and also keeps air freshness and keeps air flowing. It relates to the improvement of the bag.

  The present applicant has previously proposed a storage bag according to Utility Model Registration No. 3069083 (Patent Document 1). As shown in FIGS. 3 and 4, the storage bag has a folded nonwoven fabric tape 11 sandwiched between all edges of the two-sided film bases 10, 10 to secure an air passage 12 that communicates with the outside air. In addition, it is heat-sealed. And by having such a structure, it is effective in facilitating air venting in the bag in stacking and placing rice grains and the like, and preventing insects, foreign matter or moisture from entering the bag. there were.

  However, although the above-mentioned storage bags can prevent invading pests such as weevil from the outside, they are very rare examples when padding rice grains or after bagging. There is a possibility of getting inside.

  In order to dispel such concerns, insect-proof bags in which chili solution is kneaded into polyethylene or plastic resin as a film material have been proposed, but the effect is not certain.

  It is an object of the present invention to provide a storage bag that prevents insects from coming close to the storage bag itself and at the same time prevents the occurrence of mold and the like and prevents early damage to stored items.

  The inventor has traditionally learned to put "Chilli" and "Wasabi" into rice vines to prevent the invasion of pests such as weevil on rice grains. As a result of exploring whether it can be applied to bags, the present invention was completed.

  That is, the present invention inserts a double-folded non-woven tape on at least the edges of both ends of the double-layered base film, and secures a ventilation path that communicates with the outside air at a plurality of locations on the edges, and heats the edges on both ends. In the sealed storage bag, the nonwoven fabric tape is impregnated with a solution of chili or wasabi, and the folded portion of the nonwoven fabric tape protrudes into the storage bag. is there.

  The components of chili and wasabi impregnated in the non-woven tape act on the pests, so that the pests can approach the inside and outside of the bag and the generation of mold and the like can be suppressed.

  As the substrate film used in the present invention, a synthetic resin film is preferable. Examples of such a film include stretched polypropylene, unstretched polypropylene, vinylidene chloride coated polypropylene, high density polyethylene, low density polyethylene, polystyrene, polyethylene terephthalate, nylon, and vinylidene chloride coated nylon. Moreover, it is also possible to use a synthetic resin laminate film obtained by laminating one or two or more of non-axially stretched polypropylene, non-axially stretched linear rhodene polyethylene, or ethylene vinyl acetate copolymer resin on these synthetic resin films. . Furthermore, it is also possible to paste a decorative non-woven fabric or a vapor deposition film on the base film.

  The nonwoven fabric tape is impregnated with a solution of chili or wasabi, and the impregnation method is performed by an ordinary method such as coating or dipping.

  An example of the manufacture of the insect-proof storage bag according to the present invention is as follows. One base film is cut in half to form a two-layer base film, and chili or wasabi on both edges of the two films. A half-folded non-woven tape impregnated with the solution is sandwiched. At this time, the bent portion is directed to the inside of the film, and the tip is protruded inward from the portion to be sealed. The chili or wasabi component in this protruding portion will be allowed to act. In this state, if the two end edges are heat-sealed with a mold heat plate that has been previously made to be a ventilation path, only the missing part remains unsealed as a ventilation path communicating with the outside air. Finally, by cutting unnecessary edges, the insect-repellent freshness-keeping storage bag of the present invention can be obtained.

  Hereinafter, a preferred embodiment of the insect-repellent freshness-holding storage bag according to the present invention will be described with reference to FIGS. Note that detailed description of portions having the same configuration as the conventional example is omitted. The nonwoven fabric tape 11 is impregnated with a solution of chili or wasabi, and the nonwoven fabric tape 11 is sandwiched between all edges of the two film bases 10 and 10 so as to communicate with the outside air. It is heat-sealed after ensuring. The non-woven tape 11 has the bent portion 11a protruding inward, and the chili or wasabi component impregnated in the protruding portion acts in the bag.

  In the above configuration, when rice grains are packed from the opening, the opening edge is sealed, and the bagged rice grains are piled up in the distribution process, the air passages 12 formed at both ends of the packaging bag allow the inside of the bag to The air venting is sufficiently and easily performed without being influenced by the rice grain bags stacked up and down. Further, since the mouth of the air passage 12 is in a state of being blocked by the nonwoven fabric tape 11, the nonwoven fabric tape 11 prevents the entry of pests, foreign matters or moisture into the bag.

  When bagging rice grains, extreme care is taken to ensure that no pests or foreign substances are mixed in, but there is a risk of pests entering even during storage in the warehouse after bagging. Even in such a case, since the chili or wasabi component impregnated in the bent portion 11a protruding from the inside of the nonwoven fabric tape 11 acts in the bag, pests enter and approach the bag inside and outside the rice grain bag during storage. Can be prevented. Moreover, generation | occurrence | production of mold | fungi etc. can be suppressed simultaneously and the freshness of the stored item in a bag can also be hold | maintained.

  It is a partial front view which shows the Example of the insect-proof packaging bag by this invention.   It is an expanded sectional view which follows the AA line in FIG.   It is a partial front view which shows the conventional packaging bag.   It is an expanded sectional view which follows XX in FIG.
