Description

Plastic bag with self-sealing function

Technical Field

The utility model relates to a wrapping bag technical field, concretely relates to plastic bag with from sealing.

Background

The self-sealing bag is also called a compact bag, a bone-sticking bag, a sealing bag and a zipper bag, and the keel bag is a plastic bag which can be repeatedly sealed and is made by blowing polyethylene (LDPE) and high-pressure linear polyethylene (LLDPE) into a film and making the bag by a hot cutting machine. The self-sealing bag can be used for the internal and external packaging of various small articles (ornaments, hardware and toys). The self-sealing bag produced by food-grade raw materials can be used for storing various small foods, tea leaves, marine products and the like, and has the advantages of moisture resistance, odor tainting resistance, water resistance, insect prevention and object scattering prevention; the valve bag can also be used for packaging clothes and other daily articles, so that the valve bag has very wide application. However, the existing self-sealing bag is easy to have an unbuckled image when in use, and the reason is mainly that the displacement is caused because the strip-shaped grooves and the convex strips of the sealing component forming the self-sealing bag are soft, and the sealing feeling of whether the bag mouth is correctly sealed in place can not be generated in the sealing process of the plastic bag, so that the problem that the grooves and the flanges are often not accurately buckled is caused, and certain inconvenience is brought to the use of the self-sealing plastic bag.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a plastic bag with self-sealing which is reasonable in structure and convenient to use.

In order to solve the above problem, the utility model adopts the following technical scheme:

the utility model provides a plastic bag with from sealing, includes the bag body to and set up the first seal assembly who is used for sealing the sack at the sack, first seal assembly is including being strip setting and first recess and the first sand grip of block each other, first recess and first sand grip are fixed respectively on the lateral wall on internal both sides of bag, first seal assembly's top still is provided with second seal assembly, second seal assembly and first seal assembly are parallel to each other and are close to each other, second seal assembly includes second recess and second sand grip, second recess and second sand grip are fixed in respectively on the lateral wall on internal both sides of bag, be provided with the breach more than one on the second sand grip, the breach is the equidistance and distributes on the second sand grip.

Preferably, the first grooves, the first convex strips, the second grooves and the second convex strips are arranged in a staggered mode, and the symmetry of the plastic seal self-sealing opening is facilitated.

Preferably, anti-slip flanges are arranged on the inner walls of the two sides in the bag opening of the bag body and above the second sealing component respectively, and the anti-slip flanges and the bag body are integrally formed, so that the smooth opening of the sealed plastic bag is facilitated.

Preferably, the anti-slip flange is provided with more than one and is arranged at equal intervals, and the anti-slip flange and the second sealing assembly are parallel to each other, so that the smooth pulling-open of the mouth of the closed plastic bag is facilitated, and the slip phenomenon is reduced.

Preferably, one side of the bag opening of the bag body is higher than the other side of the bag opening, so that the bag opening can be smoothly separated.

The utility model has the advantages that: the first sealing assembly and the second sealing assembly matched with the first sealing assembly are arranged on the bag opening of the plastic bag, and the second convex strip of the second sealing assembly is provided with more than one notch, so that when the bag opening of the plastic bag is correctly sealed, a rhythmic impact feeling can be generated when the notch on the second convex strip is clamped with the second groove, so that a user can sense the rhythmic impact feeling, and the problem that the groove and the convex strip cannot be accurately buckled due to displacement of the groove and the convex strip of the sealing assembly is solved; meanwhile, the anti-slip flange is arranged on the side wall in the bag opening, so that the slip phenomenon when the sealed bag opening is opened can be reduced, and the use convenience of the plastic bag with the self-sealing bag is improved.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master.

In the present embodiment, it should be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention; in addition, in the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin fixing manner, or a pin shaft connecting manner, which is commonly used in the prior art, and therefore, detailed description thereof is omitted in this embodiment.

As shown in fig. 1-2, a plastic bag with a self-sealing opening comprises a bag body 1 and a first sealing component 2 arranged at the opening of the bag body 1 and used for sealing the bag body 1, wherein the first sealing component 2 comprises a first groove 21 and a first protruding strip 22 which are arranged in a strip shape and can be clamped with each other, the first groove 21 and the first protruding strip 22 are respectively fixed on the side walls at the two sides in the opening of the bag body 1 in an integral forming manner, a second sealing component 3 is further arranged above the first sealing component 2, the second sealing component 3 and the first sealing component 2 are parallel to each other and close to each other, the second sealing component 3 comprises a second groove 31 and a second protruding strip 32, the second groove 31 and the second protruding strip 32 are respectively fixed on the side walls at the two sides of the opening in the bag body 1 in an integral forming manner, more than one notch 33 is arranged on the second protruding strip 32, the notches 33 are distributed on the second rib 32 at equal intervals.
