Description

Fruit envelope using adhesive tape {Fruit envelope using adhesive tape}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fruit bag, and more particularly, to a fruit bag using an adhesive tape in order to facilitate the growth of young fruit and to cut off the inside of the fruit bag from the outside.

Fruit farmers use fruit cultivation methods to obtain fruit of good quality by putting fruit fruit bags on young fruits. Specifically, in the cultivation method, young fruits are selected and stored in a fruit bag, thereby suppressing the dispersion of nutrients, thereby concentrating nutrients in one fruit. The use of fruit bags prevents pesticide contamination and prevents damage from insects, birds, insects, and the like. In addition, the surface of the fruit is prevented from staining and the amount of sunshine can be adjusted to obtain fresh and high quality fruits. In order to store juveniles in a fruit bag, fruit bags have conventionally been bundled with wires, but there have been problems such as work stability and wasted manpower. In order to prevent this, a fruit bag was developed which allows the operator to easily cover the envelope.

Korean Patent No. 10-1006269, No. 10-1225095, No. 10-1421680, etc. disclose a method of joining and separating the mouths of fruit bags by using separate structures such as locks and clips. However, according to the above-mentioned patents, it is difficult to secure a space where fruit grows smoothly, which is complicated in process, is not economical, it is heavy, heavy and does not prevent foreign matter and environmental pollution, And the fruit is damaged by the structure. In order to eliminate the above problem, Applicant has proposed a fruit bag using adhesive tape in Korean Patent Application No. 2015-0006665. However, there is a difficulty in separating the release paper of the adhesive tape, and it is not decomposed into the soil, and a separate operation for recovering the release paper is required. In addition, the above application is required to reinforce the bonded portion because the strength of the bonded portion is weak.

It is an object of the present invention to provide a method and apparatus for manufacturing fruit, which is simple in manufacturing process, low in manufacturing cost, securely securing a space for growing fruits, light in weight, preventing foreign matter and environmental pollution, To provide a fruit bag which is easy to separate the release paper, is decomposed in the soil, does not recover the release paper, and increases the strength of the joint part.

The present invention provides a fruit envelope having an envelope inlet formed with front, back, and corners and having an opening for inserting a young fruit, wherein the rear surface is protruded from the front surface, and the envelope inlet And an adhesive tape is disposed on at least one of the front surface of the suture part or the front surface of the suture part where the suture part is folded, wherein the adhesive tape is composed of a release film and an adhesive layer, Is larger than the width of the adhesive layer, thereby forming a release space in which the release film is separated.

In the envelope of the present invention, the adhesive layer may be formed by sequentially laminating an envelope adhesive layer, a substrate, and a substrate adhesive layer. The envelope adhesive layer and the base material adhesive layer may be formed by applying any one of an adhesive, a synthetic resin adhesive, and a natural resin adhesive.

The release film is preferably a biodegradable film coated with at least one selected from a silicone resin, a fluororesin, a polyvinyl alcohol, a paraffin, a wax, and a Teflon dispersion. The biodegradable film may be a paper, a polyester amide, a polyester carbonate, a polybutylene succinate adipate, a polybutylene succinate, a polycaprolactone, a cellulose acetate, a bacterial cellulose, a cellulose ochitosan complex, And at least one selected from the group consisting of lactose, polyglyoxylic acid, polyglycolic acid, polyamino acid, polysaccharide, starch, and modified starch. Wherein the biodegradable film is made of at least one of a 3-hydroxybutyrate homopolymer, a 3-hydroxybutyrate / 3-hydroxyvalerate copolymer, and a 3-hydroxybutyrate / 4-hydroxybutyrate copolymer . A reducing material may be added to the release film.

According to the fruit envelope using the adhesive tape of the present invention, by using the adhesive tape having the release film which is wider than the adhesive layer, the manufacturing process is simple, the manufacturing cost is low, the space for growing the fruit is secured smoothly, And it is easy to isolate the release film. Further, the release film of the adhesive tape can be decomposed in the soil using the biodegradable material to prevent environmental pollution by the release film. Since the release film is biodegradable, a separate operation for recovering the release paper is not required. Furthermore, the adhesive tape can cover the jointed portion of the fruit bag to increase the strength of the joint portion.

Furthermore, the adhesive tape can cover the jointed portion of the fruit bag to increase the strength of the joint portion.

 1 is a perspective view of a first fruit bag 100 using an adhesive tape according to an embodiment of the present invention, as viewed from the front.

1, the first fruit bag 100 comprises a front surface 10, a rear surface 11 and an edge 12 and forms a substantially rectangular parallelepiped. Preferably, the edge 12 can be folded at least once. Particularly, the portion having the folded portion of the edge 12 more than once is called a multiple folded portion. In the drawing, the folded state is shown once. It is preferable that the folded portion of the multiple folded portion extends freely toward the center of the first fruit bag 100 and extends to the vicinity of the center. The lower end of the first fruit bag 100 is provided with a sealing portion 13 to which the rear face 11 is extended and joined and at least one drain hole 14 for discharging moisture inside is disposed. In the drawing, two drains 14 are exemplified. The drain port 14 can be in the form of a perforated opening and can be made naturally as a space formed between the seal 13 and the edge 12. Here, we have expressed a hole-shaped form.

The rear surface 11 extends from the front surface 10 and protrudes, and the protruded portions are separated on both sides around the cutting line 23. That is, a part of the rear face 11 is directly bonded to the front face 10 with respect to the cutting line 23 and the rest is bonded to the front face 10 via the adhesive tape 30 (22). The direct bonding portion 21 is bonded to the front surface 10 with an adhesive such as a paste to improve durability such that the first fruit bag 100 is not damaged or deformed by an external force. It is possible to prevent the front surface 10 and the rear surface 11 from being twisted by the direct bonding portion 21. [ The width W1 of the suture part 22 can be variously adjusted depending on the type of young fruit. The fruit juice may be apples, pears, grapes, etc., and the width W1 of the suture part 22 may be varied in consideration of the process of growing the fruit and the convenience of the work. Preferably about half of the width of the front surface 10 is preferable.

The front side 10 together with the back side 11 forms a space into which young fruit is inserted and the end of the front side 10 defines the envelope inlet 20. The portion where the cutting line 23 and the envelope inlet 20 meet is preferably provided with a tap insertion portion 24 into which a juice is inserted. That is, the nipple of the young fruit is exposed to the outside of the first fruit envelope 100 through the nipple insertion portion 24. The cut portion is rounded, polygonal or the like, but it is preferable that the cut portion 22 is rounded to match the shape of the nipple of the young fruit, as shown in the figure.

The first fruit bag 100 according to an embodiment of the present invention is not limited to a specific one, but may be any one selected from a newspaper, a paper bag such as an oil paper, a synthetic resin bag, or an envelope combined with them. In some cases, a thin layer of metal or ceramic may be attached to extend the function of the first fruit bag 100. The first fruit bag 100 can be made of a single layer, but multiple layers are preferred. In order to reinforce the rigidity of the suture part 22, a back surface of a portion corresponding to the suture part 22 may be attached to a thin plate selected from paper, synthetic resin, metal, or ceramic. The pad method can be implemented by adhesion or the like.

The adhesive tape 30 is composed of a release film 31, an adhesive layer 32 composed of a substrate adhesive layer 32a, a substrate 32b and an envelope adhesive layer 32c. As the envelope adhesive layer 32c, the base material 32b and the base material adhesive layer 32a, a conventional double-sided adhesive tape can be applied. The envelope adhesive layer 32c may be different in adhesive depending on the material of the first fruit bag 100 and the release film 31. [ That is, the type of the adhesive can be controlled depending on whether the material is paper or synthetic resin. The envelope adhesive layer 32c is not limited as long as the seal portion 22 and the front surface 10 can be adhered to each other. That is, the envelope adhesive layer 32c can be made of any known pressure sensitive adhesive and adhesive. The pressure-sensitive adhesive is a pressure-sensitive adhesive which is cured in a semi-solid state when heat-treated at a predetermined temperature and time. Specifically, the pressure-sensitive adhesive may be a pressure-sensitive adhesive mixed with an acrylic polymer, a silicone-based polymer or a urethane-based polymer, a thermosetting resin or a thermosetting resin, an ultraviolet-curing resin and a crosslinking agent, or a mixture thereof or a copolymer thereof.

The adhesive may be a synthetic resin-based adhesive or a natural resin-based adhesive. Examples of the synthetic resin system include a thermosetting resin, a thermoplastic resin, a styrene rubber, a phenol resin, and an epoxy resin. The thermosetting resin includes a urea type, melamine type, phenol type, unsaturated polyester type, epoxy type, resorcinol type, Examples of the thermoplastic resin include vinyl acetate, polyvinyl alcohol, vinyl chloride, polyvinyl acetal, acrylic, saturated polyester, polyamide, and polyethylene. The styrene rubber may be a butadiene rubber type, a nitrile rubber type, a butyl rubber type, a silicone rubber type, a chloroprene rubber type or the like, and the phenolic resin may be a vinyl type, phenol-crooprene rubber type, Epoxy system and the like. Examples of the natural resin system include starch, dextrin, glue, casein, latex, gum pulp, rosin, shellac and the like.

The base material 32b may be a material selected from paper, synthetic resin, metal, or a combination thereof. The base material 32b is a synthetic resin film, preferably polypropylene, polyethylene, polyethylene terephthalate, polylactic acid, polyamide and the like. But is not necessarily limited thereto. The base adhesive layer 32a may be different in adhesive depending on the material of the base material 32b. That is, the type of the adhesive can be controlled depending on whether the material is paper or synthetic resin. The base adhesive layer 32a may be made of the same material as the envelope adhesive layer 32c, but different materials may be applied to different adhesive strengths. As the substrate adhesive layer 32a, both of the above-mentioned pressure sensitive adhesives and adhesives can be applied.

The releasing film 31 is removed when the sealing portion 22 is attached to the adhesive tape 30. The release film 31 is preferably a biodegradable film coated with a release layer such as a silicone resin, a fluororesin, a polyvinyl alcohol, a paraffin, a wax, a Teflon dispersion or the like. (A) of the release film 31, which is larger than the width (b) of the adhesive layer 32. That is, a release space for separation is formed between the release film 31 and the front surface 10. The difference (a-b) between the widths is enough to easily peel off the release film 31 by the operator. By thus setting the release space, the operator can easily separate the release film 31 from the adhesive layer 32.

When the biodegradable film is removed and dropped to the ground, it is decomposed and does not cause environmental pollution problem. The biodegradable film may be made of a material selected from the group consisting of paper, a polyester amide, a polyester carbonate, a polybutylene succinate adipate, a polybutylene succinate, a polycaprolactone, a cellulose acetate, a bacterial cellulose, a cellulose ochitose complex, a polylactic acid, At least one selected from the group consisting of polyglyoxylic acid, polyglycolic acid, polyamino acid, polysaccharide, starch, and modified starch. Wherein the biodegradable film is made of at least one of a 3-hydroxybutyrate homopolymer, a 3-hydroxybutyrate / 3-hydroxyvalerate copolymer, and a 3-hydroxybutyrate / 4-hydroxybutyrate copolymer . In some cases, the soil can be improved by introducing a useful substance into the soil, such as reducing materials such as iron, copper, zinc, and sulfur compounds, on the release film 31.

The operator stores the fruit portion of the young fruit consisting of the nipple and the fruit in the first fruit bag 100. When the young fruit is housed, the release film 31 is removed and the suture part 22 is folded to adhere to the front face 10. At this time, since the substrate of the release film 31 is a biodegradable material, it does not contaminate the soil even if the removed release film 31 is dropped on the ground. When the suture part 22 is adhered to the front face 10, the suture part 22 seals the first fruit envelope 100 except for the nipple of the young fruit. The folded suture part 22 serves as a cover for preventing rain, foreign matter and the like from penetrating. That is, the lid prevents rain or foreign matter from penetrating into the first fruit bag 100. The conventional fruit envelope is a separate structure that closely adheres to the mouth of the fruit envelope, so that it is not possible to completely block the penetration of rain or foreign matter. This is because, if the adhesion is loosened due to the defect of the separate structure, or if the adhesion is loosened by the impact such as the wind or the like, there is a possibility that the rain or the foreign substance penetrates. However, since the lid of the present invention is covered with the rear face 11 rather than the close contact type, there is no problem that the lid is loosened originally.

On the other hand, the adhesive tape 30 according to the embodiment of the present invention is inserted into the process of manufacturing the first fruit bag 100 in a state of being wound around the winding roll in the form of a band. At this time, the band-shaped adhesive tape 30 is wound on the winding roll in a state in which the release film 31 is covered on the adhesive layer 32 continuously. A part of the strip-shaped adhesive tape 30 may be cut and attached to the first fruit bag 100, so that the process is simplified. In addition, since the release film 31 is biodegradable, there is no need to collect the release film 31, and the efficiency of the sealing operation can be increased.

FIG. 2 is a perspective view of a fruit envelope 100a in which a first fruit bag 100 using an adhesive tape according to an embodiment of the present invention is deformed, as viewed from the front. The deformed fruit envelope 100a of the first fruit envelope 100 is the same as the first fruit envelope 100 except that the adhesive tape 30a covers the junction 21 directly. Accordingly, detailed description of the overlapping portions will be omitted.

2, the deformed fruit envelope 100a is adhered in such a manner that the adhesive tape 30a covers a part of the joining portion 21. As shown in Fig. To this end, the release film 31 and the adhesive layer 32 of the first fruit envelope 100 extend onto the abutment 21. The elongated adhesive tape 30a is adhered to the joint 21 so that the deformed fruit envelope 100a keeps the shape of the fruit envelope 100a firm by an external force such as wind or worker's force. When the first fruit bag 100 is subjected to a strong external force, the front face 10 may be broken at a portion where the bonding portion 21 and the front face 10 meet. However, by extending and attaching the adhesive tape 30a, it is possible to prevent the front surface 10 from being broken at the portion where the adhesive tape 30a is stuck.

The releasing film 31 is removed when the sealing portion 22 is attached to the adhesive tape 30a. The release film 31 is preferably a biodegradable film coated with a release layer such as a silicone resin, a fluororesin, a polyvinyl alcohol, a paraffin, a wax, a Teflon dispersion or the like. (A) of the release film 31, which is larger than the width (b) of the adhesive layer 32. That is, a release space for separation is formed between the release film 31 and the front surface 10. The difference (a-b) between the widths is enough to easily peel off the release film 31 by the operator. By thus setting the release space, the operator can easily separate the release film 31 from the adhesive layer 32.

When the biodegradable film is removed and dropped to the ground, it is decomposed and does not cause environmental pollution problem. The biodegradable film may be made of a material selected from the group consisting of paper, a polyester amide, a polyester carbonate, a polybutylene succinate adipate, a polybutylene succinate, a polycaprolactone, a cellulose acetate, a bacterial cellulose, a cellulose ochitose complex, a polylactic acid, At least one selected from the group consisting of polyglyoxylic acid, polyglycolic acid, polyamino acid, polysaccharide, starch, and modified starch. Wherein the biodegradable film is made of at least one of a 3-hydroxybutyrate homopolymer, a 3-hydroxybutyrate / 3-hydroxyvalerate copolymer, and a 3-hydroxybutyrate / 4-hydroxybutyrate copolymer . In some cases, the soil can be improved by introducing a useful substance into the soil, such as reducing materials such as iron, copper, zinc, and sulfur compounds, on the release film 31.
