Description

Technical Field

[0001] The utility model belongs to the field of soft packaging, and in particular relates to an all-round anti-oxidation soft packaging structure. Background Art

[0002] Soft packaging is a form of packaging made of flexible materials. It has the advantage of being easy to deform and is compatible with fluid items. It is often used to package fluid items. However, ordinary soft packaging only achieves physical sealing and cannot completely isolate oxygen from penetrating into the soft packaging. After the soft packaging has been placed for a long time, oxygen will penetrate into the soft packaging and oxidize the packaged items. In view of the situation where oxygen will penetrate into the soft packaging, the packaging bags of soft packaging that require oxygen isolation are usually made of materials that can isolate oxygen. However, the suction nozzle of the soft packaging still cannot isolate oxygen from penetrating. After being placed for a long time, the packaged items will still be oxidized.

[0003] In the prior art, for example, the patent document with publication number CN106742612A discloses a recyclable and reusable soft packaging bag for packaging oxidized film drying offset printing ink, wherein the soft packaging bag comprises a high barrier film and a specific structure, wherein the high barrier composite film is a high barrier multi-layer co-extruded film or pure aluminum foil or VMPET or MXD6 nylon or silicon oxide vapor-deposited film or K film or A film, which is composited with PE, PA, PET, PP, and various paper films to prevent oxygen molecules from penetrating the high barrier film and contacting the ink. However, the nozzle of the soft packaging bag cannot isolate oxygen, which still causes oxygen to penetrate into the packaging bag.

[0004] Therefore, there is an urgent need for a flexible packaging structure that is fully resistant to oxidation to solve the above problems. Summary of the invention

[0005] In view of the problems in the prior art, the utility model proposes an all-round anti-oxidation soft packaging structure.

At the same time, aluminum foil is relatively soft, has good ductility, is easy to deform, and is compatible with the characteristics of flexible packaging.

[0009] Preferably, the anti-oxidation inner plug is provided with a lower groove at a position corresponding to the outer top surface of the cover body, and the anti-oxidation inner plug is formed by the bottom and side walls of the lower groove.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 7 As shown, a fully anti-oxidation soft packaging structure comprises a sealed bag body 1 and a sealed nozzle 2 which are sealed to each other, wherein the sealed bag body 1 comprises an inner cavity formed by at least two soft films being heat-melted and sealed to each other along their edges, and the soft films comprise at least one anti-oxidation layer;

[0029] In this embodiment, the anti-oxidation layer is made of a material that prevents oxygen from penetrating.

[0030] Specifically, the anti-oxidation layer is aluminum foil. Aluminum foil has the advantage of good barrier properties. When the surface of aluminum foil is oxidized, aluminum oxide will be generated, which can effectively prevent oxygen from penetrating into the flexible packaging bag. At the same time, aluminum foil is relatively soft, has good ductility, and is easy to deform, which is compatible with the characteristics of flexible packaging.

[0031] The sealing nozzle 2 comprises a pipe fitting 22 and a sealing cover 21. A connecting wing 221 is provided at one end of the pipe fitting 22.

When the cover 211 is rotated back, the ratchet 223 presses against the claw 2131 to deform the anti-reverse hoop so that the breakpoint structure is disconnected. The anti-theft hoop component 213 is used to prevent the items in the soft package from being stolen. When the items in the soft package are stolen, the cover 213 needs to be unscrewed, and the breakpoint structure will be destroyed at this time, so that the anti-theft hoop component 213 plays an anti-theft role.

[0036] The anti-oxidation inner plug 212 extends inwardly along the tube hole 222 to the corresponding position where the soft film and the tube 22 are heat-sealed, and the surface of the anti-oxidation inner plug 212 is provided with an anti-oxidation layer, and the anti-oxidation layer of the anti-oxidation inner plug 212 is complementary to the anti-oxidation layer of the soft film, so that the inner cavity of the soft package is completely covered by the anti-oxidation layer, thereby improving the anti-oxidation property of the soft package.

[0037] In this embodiment, the diameter of the anti-oxidation inner plug 212 is adapted to the diameter of the tube hole 222, so that the inner cavity is formed into a sealed environment, thereby improving the sealing performance of the soft package.

[0038] In this embodiment, the side wall of the anti-oxidation inner plug 212 is provided with at least one convex ring, which abuts and seals against the inner wall of the tube hole 222. The convex ring or sealing ring further improves the sealing of the inner cavity, thereby improving the reliability of the sealing nozzle 2.

[0040] In this embodiment, the anti-oxidation inner plug 212 is provided with a lower groove 2121 at a position corresponding to the outer top surface of the cover body 211, and the anti-oxidation inner plug 212 is formed by the bottom and side walls of the lower groove 2121. The lower groove 2121 is used to reduce the material of the cover body 211 and reduce the production cost of the cover body 211.

[0041] In this embodiment, the sealed bag body 1 includes an inner cavity formed by three soft films that are heat-melted and sealed along their edges. One of the soft films is located at the bottom of the bag body, and its edges are heat-sealed to the edges of the other two soft films.
