Do it. It is possible to protect the damage of the contents by injecting air in a packaged state provided with an air inlet as described in Republic of Korea Patent Publication 2002-0075059.

Recently, with increasing interest in health, more and more consumers are seeking to buy fresher, more eco-friendly ingredients. In addition, fresh vegetables, such as juicers and juicers, are processed directly and eaten at home. Accordingly, fresh vegetables are often purchased and stored at home, and a lot of airtight storage containers for fresh vegetables are also developed and sold. However, in the case of vegetables whose freshness is vital, it is also important to maintain freshness at the storage stage, but it is also very important to maintain freshness at the stage of cultivation in the mountain region and then transported. In general, vegetables grown in the mountains are passed to the consumer for a considerable time through the screening or packaging step, and oxidation or damage may occur in the process. In the process from the cultivation site to the consumer, the raw materials such as vegetables are initially processed and packed in units that are easy for the consumer to use, and the consumer can open and use the packaging to easily reclose and store the remaining materials. If so, the freshness in the mountains can be maintained for a long time, and consumers can conveniently use the freshness of the ingredients.

Recently, the packaging structure to maintain the freshness of the product even after opening is equipped with a zipper structure in the packaging bag sealed by heating (heating), widely used, it is used as a packaging structure for maintaining the freshness of frozen processed foods or meat processed products It is becoming. Republic of Korea Patent Registration 10-0615945 or Korean Utility Model No. 1998-026445 has a structure having a zipper on the packaging bag. This sealed package is equipped with a zipper and can be resealed in a packaging form. In addition to the simple sealing, injecting gaseous gas such as nitrogen not only protects the contents through the filling material, but also provides fresh food such as vegetables. By inhibiting oxidation it will be possible to maintain good freshness for a certain period of time.

The present invention has been made to solve the above-mentioned problems, and has a heat-adhesive portion (02) and a reclosable zipper portion (04) for heating and bonding to the inlet of the packaging bag by heating with a hot wire, injecting air therebetween Air inlet (03) is provided, the filling gas such as hydrogen or nitrogen is injected into the air inlet in the state of sealing the heat-adhesive part to suppress oxidation and protect the contents to maintain the freshness, even after opening by the user The purpose is to provide a structure of a pouch that can be sealed.

In order to solve the above problems, the double airtight packaging pouch structure having a one-way air inlet according to the present invention is an opening that can put the contents in the open state (01), the heat adhesive portion that can be heated and bonded to the heating wire (02) , Zipper section (04) that can be repeatedly opened and closed to store the pouch, one air inlet (03) between the heat-adhesive section and the zipper section, a cutout (05) between the one air inlet and the zipper section and the bottom of the packaging bag It consists of (06).

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a packaging pouch structure according to the present invention. A general packaging pouch is a structure in which the opening of the upper part is in close contact with a heating wire or is closed using a zipper to expand the structure so that the bottom surface can be erected. The double sealed pouch structure having a single air inlet according to the present invention is an upper end of the pouch inlet, an opening for placing contents in an open state (01), and a heating wire at the bottom of the opening to heat the vinyl on the front and back of the pouch. The heat-adhesive part (02) capable of melting and adhering, the pouch part (22) horizontally formed in the inner side of the front and back vinyl with the uneven structure of the male and female so that the pouch can be repeatedly opened and closed, the heat-adhesive part (02) and the zipper part (04) between the one air inlet (03), one air inlet (03) and the zipper section (04) to cut the discharge of the internal air between the inlet to allow the air to be injected from the outside horizontally Consists of a cutout portion (05) having a groove formed on one or more sides and a bottom portion (06) formed so as to support the contents by unfolding the lower portion of the packaging bag form, and opening the opening (01) of the pouch. Injecting a filling gas such as nitrogen or hydrogen into the one air inlet 03 in a sealed state by heating and sealing the heat-adhesive part 02 can be packaged to protect the contents and suppress the oxidation to maintain the freshness, when used In the cut out part (05) to take out the contents and then lock the zipper (04) can be repeatedly reclosed to keep the contents.

Figure 2 is a detailed view of the zipper portion of the packaging pouch according to the present invention. As is well known, the packaging material is used in a zipper-bag having a concave-convex portion on both sides of the packaging material and attached to the front and back sides of the bag. One side is formed of a female zipper (04a) having a concave portion (04a1) and a male zipper (04b) having a convex portion (04b1) at one side of the front and rear surfaces of the pouch, which is a plastic packaging material, and both ends thereof are coupled to each other. In this state, the extremes are coupled to each other so as not to open even when opened. The structure of the zipper bag is often used as an advantage that can be repeatedly resealed even after opening, but when the product is released, the sealing force may not be stable, so that the upper part of the zipper (outer side) is tightly melted and sealed by using a hot wire. Improves sealing stability

3 is a cross-sectional view of one air inlet of the packaging pouch according to the present invention. One air inlet 03 is composed of an air inlet portion (031) that is an inlet for injecting air and a backflow cutoff portion (032) of a membrane structure in which a portion is fixed in a planar shape with elasticity, and the backflow cutoff portion is formed by elasticity. By keeping the plane state, it maintains the closed state by the pressure of the inner air and keeps the blocked state so that the internal air does not flow out to the outside. When the air is forcibly injected from the outside, the air is injected more strongly than the pressure of the air inside the pouch. In this case, it is characterized by being able to inject air by pushing the reverse flow blocking membrane structure inward by elasticity. That is, when the air pressure inside the pouch is higher than the outside pressure, the flow of air is blocked so that the internal air does not leak out by the backflow blocker 032 and the outside air does not seep out. This prevents the loss of gas filling to preserve the contents and inhibits oxidation due to external air ingress.

Figure 4 is a cross-sectional view for explaining the use step of the packaging pouch structure according to the present invention. The contents are put in the state <a> which opened the opening part 01 of the pouch by this invention, and the upper end is sealed by melting and adhering the heating adhesive part 02 of the upper end with the heat sealing machine 10, and <b>. The air is injected into the pouch using the air injector 20 in the one air inlet 03 in a state where the upper end is sealed. The injected air can be easily obtained, such as nitrogen or hydrogen, and can be a gas that can inhibit oxidation of the contents. When the gas to be filled is sufficiently injected <c>, the shape of the pouch becomes taut due to the characteristics of the vinyl material <d>. In this state, the packaged product is distributed and shipped. Oxidation is inhibited by the filling gas inside the pouch and the contents are protected to prevent deterioration or damage during distribution. When the consumer purchases the product and tears off the package, the cutout part 05 is cut and cut in the horizontal direction, and the waste part 100 is separated from the storage part 200 containing the contents after the cutout. Already opened, the filling gas inside the pouch is lost, but can be used in the form of <f> to keep the fresh state for a certain period of time since the outside air is blocked by the zipper (04).

Figure 5 is a perspective view of the use step of the packaging pouch structure according to the present invention. Put the contents in the stand up pouch <a-1> and close the heating adhesive <b-1> to distribute and transport the products. The consumer purchases the product, locks the zipper section <c-1>, removes the disposal unit 100 after cutting, and stores the storage unit 200 containing the contents in the refrigerator. can do. In this way, in the production stage, filling gas such as nitrogen or hydrogen can be injected in the sealed state to increase the freshness of the contents, and consumers can keep the freshness for a long time even during the use process because the zipper can be stored in the remaining materials that have already been opened and used. have.

Figure 6 is a perspective view of another embodiment of the packaging pouch structure according to the present invention. Unlike the above-described embodiment, the contents of the pouch according to the present invention are packaged in two or more kinds, for example, cultivated with Chinese cabbage and radish as a bundled product, or processed a variety of vegetables and fruits for salad or green juice It is a form that can be applied when the product is contained separately. Pouch inlet-side upper end, the opening portion (01) to put the contents in the open state and the heat adhesive portion (02) for melting and bonding the vinyl on the front and back of the pouch by heating the heating wire at the bottom of the opening (01) and

The upper end portion (A) is composed of one air inlet (03) to block the discharge of the internal air at the lower end of the heat adhesive portion and to inject air from the outside. Vertically divides the space for putting contents under the upper part of the pouch into two or more spaces to closely contact each space with the close contact part 10, and horizontally cuts the upper part to form a groove at the left and right ends so as to be separated. It has a vertical cutout portion 05b composed of a cut line 05b1 and a groove which can be divided by cutting the cutout portion 05a and each space vertically to cut and separate each space. In order to store the pouch and open and close it repeatedly, a zipper part (04) horizontally formed inside the front and back vinyl with a male and female uneven structure at the top of each divided space and a bottom part formed to support the contents by unfolding the lower part of the pouch ( 06) is configured as the lower end (B). The upper end (A) is maintained until the product packaging step and distribution step, when the user opens the product is separated and discarded. The user keeps only the lower portion B by separating each space. Open the opening of the pouch (01), put the contents in each space divided into two or more in the lower end (B), and heat-adhesive (02) of the upper end (A) in a state of sealing tightly sealed, one air inlet ( Filling gas, such as nitrogen or hydrogen, is injected into 03) and the zippers 04 provided in the respective spaces of the lower ends are locked and sealed to protect the contents and to prevent oxidation. After opening, the cutout portion 05 is cut to separate each space of the lower end portion B, and the structure can be stored separately by repeatedly resealing the zipper portion 04. In this way, by dividing the space to make an incision, and filling the inside of the pouch with a filling gas to maintain freshness and sealed with a zipper for each space, to purchase fresh ingredients and use only as much as necessary, unused materials unopened In addition to maintaining freshness, there is an advantage in that various ingredients for making one food can be packaged separately in one package. For example, green vegetables such as kale, celery, and fresh vinegar, as well as cabbage, fruits, and carrots are used to make green juice. When fresh vegetables grown on farms are divided into different types and sold in one pouch, consumers can easily purchase green juice ingredients. Can be stored separately. In addition to the green juice, it is possible to construct a product by varying the division ratio of the space according to the frequency and preference of each ingredient, such as salad, various herbs, and ingredients for making kimchi. In addition, by dividing a single material by space, only the required amount can be opened and used, and unused materials can be kept unchanged and kept fresh.

Although a preferred embodiment of the double-sealed pouch structure having a single air inlet according to the present invention described above has been described, the present invention is not limited thereto, but the scope of the claims and the detailed description of the invention and the accompanying drawings are various. It is possible to perform the transformation to this also belongs to the present invention.
