Description
Technical Field
The utility model relates to a flexible container technical field especially relates to an anti-swelling inner membrane bag.
Background
The flexible container has large bearing capacity, large volume capacity and light weight, and may be used widely in transportation, packing and storage of food, grain, medicine, chemical industry, mineral product and other powder, granule and block.
The flexible freight bag used in the market generally has a double-layer structure of an inner bag and an outer bag, the inner bag is a PE film, the outer bag is a PP film, the loading capacity of the flexible freight bag is poor, the flexible freight bag is easy to expand and tear when being used for loading articles with high density, the flexible freight bag does not meet the use requirement, and aiming at the problem, the packaging form that the inner bag is provided with the lacing wire is gradually used in the domestic market.
Chinese patent document CN 202038608U discloses a formed inner lacing bar piece type flexible container, which comprises a bag body, a bag cover and a bag bottom, wherein the bag body is internally provided with inner lacing bar pieces, and the inner lacing bar pieces are longitudinally arranged at four opposite corners of the bag body, so as to improve the loading capacity. However, the structure has the disadvantages that when the density of the articles in the bag is higher, the expansion phenomenon still occurs, the occupied area is increased, and the loading capacity in a limited space is influenced; in addition, the inner bag and the outer bag of the conventional packaging bag are generally bonded together by adhesives such as glue or adhesive tapes, which can contaminate the inner bag. For the food grade or the medicine grade, which have strict requirements on the hygienic index, the articles are easy to pollute, and further the storage of the food or the medicine is influenced, and the use safety of the food or the medicine is influenced.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned technique, provide a loading capacity height prevent the interior membrane bag that expands, need not to use glue just can connect in the outer bag, effectively prevented the inflation of flexible container.
In order to realize the purpose of the utility model, the utility model adopts the technical scheme that: an anti-expansion inner film bag comprises an inner bag body arranged in an outer bag of a packaging bag, wherein the inner bag body consists of a top panel, a main body part and a bottom panel from top to bottom, the main body part is of a cuboid structure, a feed inlet is formed in the center of the top panel, and a discharge outlet is formed in the center of the bottom panel; vertical fins are arranged on the outer edge of the main body part along four side ridge lines respectively, and each fin shares one side with the corresponding side ridge of the main body part.
Further, the top panel and the bottom panel are of a quadrangular pyramid structure.
Further, the length of interior lacing wire piece equals with the height of main part, and the through-hole on each interior lacing wire piece is not less than three to along the central axis of interior lacing wire piece from top to bottom even interval distribution.
Furthermore, the top panel, the main body part, the bottom panel, the fins, the feed inlet and the discharge outlet are of a PE film integrated structure.
Furthermore, the two flashes on each side edge of the inner bag body are arranged, at least three pairs of symmetrical connecting holes are formed in each side face of the inner bag body from top to bottom, and each pair of symmetrical connecting holes are connected through a binding line, so that the anti-expansion effect is further achieved, and the three-dimensional effect is better.
Furthermore, the flash is rectangular, and the width of the flash is 5-10 cm.
Furthermore, the overlap of the inner bag body is connected to the outer bag through sewing, glue bonding is not needed, the connection strength is high through a sewing mode, and the environmental protection performance is good.
The utility model has the advantages that: the inner bag of the flexible freight bag is provided with the inner lacing bar pieces and the flanges, so that the flexible freight bag can be effectively prevented from expanding after being filled with materials, and meanwhile, the flexible freight bag has an obvious three-dimensional effect; meanwhile, the inner bag is connected with the outer bag in a sewing mode through the vertical flash, and compared with glue, the inner bag is green and environment-friendly and free of pollution, and compared with hot melting connection, the inner bag is higher in connection strength and better in three-dimensional effect.
