Description

Self-expanding non-woven cloth bag

Technical Field

The utility model relates to the field of packaging bags, in particular to a self-expanding non-woven bag.

Background

The non-woven fabric has the characteristics of moisture resistance, air permeability, flexibility, light weight, no combustion supporting, easy decomposition, no toxicity or irritation, rich color, low price, recycling and the like, is widely applied to life, and has the advantages of practicability, environmental protection and the like when being used as a manufacturing material of the handbag. However, the nonwoven fabric bag is biased to be soft as other conventional bag bodies, and is often easily unfolded incompletely in a conventional state, such as a state in which the side surface is collapsed and folded inwards. And in some cases, when the rigid state is required to be formed, the rigid effect cannot be formed, and the application range is narrow. For example, when the non-woven fabric bag needs to be used for placing products such as cakes, the inner side surface of the soft and collapsed non-woven fabric bag can contact the upper end of the cake, and therefore the attractiveness of the cake is affected.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problems, the present invention provides a self-expanding nonwoven fabric bag:

When being in the bag body shrink state, detain two handle portions in the arc recess this moment, inject the expansion of the bag body to can keep the bag body to be in the shrink state all the time. The arc-shaped groove can be used for clamping and reversing the handle part, and can also be matched with the buttocks of a human body to be used as a simple inflatable seat.

Preferably, the air bag strip sequentially comprises an elastic film material layer and a reticular metal wire layer which are fixedly bonded with each other from outside to inside, and the bottom of the arc-shaped groove is provided with a magnetic strip which forms magnetic attraction matching with the air bag strip.

Preferably, square ring off-plate surface is from last to fixed the gasbag ring that bonds to have a plurality of align to grid and intercommunication gasbag strip down, the gasbag ring is used for launching two other sides of the bag body, has improved the whole effect of launching of the bag body. In daily application, two narrower sides of the bag body are often in the state that the V-shaped is not fully expanded, the air bag ring is inflated to become firm, the two narrower sides of the bag body tend to be straight as much as possible by the arrangement of the air bag ring, and the opening degree of the bag body is improved.

Preferably, the outer edge of the square ring surface is fixedly provided with a square frame matched with the square ring surface, the inner side of the square frame is provided with a limiting hole for the air bag strip to pass through, and when the air bag strip is buckled in the arc-shaped groove, the square frame and the air bag strip form limiting matching.

Preferably, one side of the square frame, which is close to the elastic bottom bag, is provided with four mounting grooves corresponding to the side faces, four support rods movably hinged with the square frame are arranged in the mounting grooves, and the support rods and the inner plate form a top-leaning support fit. When the product is used as a seat, the support rod plays a good supporting role at the moment.

Has the advantages that: when the elastic bottom bag is filled with gas, the air bag strips are stiffened by the gas, and the connecting strips are mutually bonded with the outer surface of the bag body, so that the whole bag body is driven to automatically expand upwards and outwards in the expansion process of the air bag strips. In addition, when the article is placed in the bag body, the article can generate corresponding acting force on the elastic bottom bag to cause gas to enter the air bag strip, so that the stiffness of the air bag strip is improved, and the bag body is favorably unfolded. The elastic bottom bag has the beneficial effect of buffering and protecting articles, and has better bearing capacity for a double-layer structure. In addition, the handle part in the inflated state is more convenient for a user to grab without generating corresponding strangle marks.
