Description

The packaging bag of with closure

Technical field:

The utility model belongs to flexible package thing field, particularly a kind of packaging bag of with closure.

Background technology:

Flexible plastic cement packaging bag is used to contain solid-state and liquid article in a large number, mostly be non-returnable container greatly, also promptly in case after opening, be difficult to row sealing again, cause unspent article to get damp easily, especially be easy to water absorbing article in order to splendid attire such as tealeaves, milk powder or laundry soap powder etc.For this reason, the user opens an osculum at be everlasting packaging bag angle place, conveniently takes out or topples over article, then with a clip opening is clamped, and prevents to get damp; The inspiration that the manufacturer is subjected to creates the packaging bag that has sealed of multiple male and female groove at sack, makes after the packaging bag unpacking, can repeat encapsulation process again.This package construction is compounded with one sealed below sack hot sealing band, when breaking seal for the first time, cut off sack hot sealing band, opens sealed again and takes built-in article, and compressing sealed after the use is the resealable sack.Though this packaging bag brings moistureproof effect, but when built-in powder article were being toppled in female groove of falling into sealed, its sealed again was difficult to sealed sealing, and needing to remove totally could be sealed again, therefore only be fit to the article of some granularities of packing, have certain limitation greater than groove width.

Summary of the invention:

To be that design is a kind of applicablely repeat to open and close leak free packaging bag with cover with what contain particulate solid and powder to the purpose of this utility model.

Technical solutions of the utility model are achieved in that a kind of packaging bag of with closure, it is characterized in that being compositely fixed with the bag mouth that a band is torn diaphragm seal on the bag one side, are equipped with a lid that can repeat to open and close on the bag mouth.Because the bag mouth is located on the face of bag, do not influence hot pressing compound seal of bag two ends and loading operation, a bag mouth itself has diaphragm seal, can guarantee to produce, the tightness of transportation and storage, can utilize lid again after opening use, realize repeating the demand of sealing.

But described bag mouth and lid have the adhesion portion of a bending, bag mouth, lid and to tear diaphragm seal be a disjunctor injection mo(u)lding.Not only shaping efficiency height, and lid and bag mouth adhesion do not worry that lid loses.

Described bag mouth and lid are one of flush fit or interference fit structure.Article such as minimizing powder reseal the influence of operation to the bag mouth.

The utlity model has reasonable in design, cost is cheap relatively, easy to use, have repetition leak free characteristics, set up a bag mouth that can repeat to open and close, neither influence the article flow package, offer convenience for using again, especially be fit to packaged solid state class article, and lid and bag mouth employing rational structure fitted seal, it opens and closes the influence that is not subjected to the content product again.

Description of drawings:

Below in conjunction with concrete legend the utility model is described further:

Wherein

1-bag 2-bag mouth 21-tears diaphragm seal

22-handle 3-lid 4-adhesion portion

The specific embodiment:

See figures.1.and.2, a kind of packaging bag of with closure, be compositely fixed with one bag of mouth 2 on its bag 1 one side, disjunctor has a band to tear diaphragm seal 21 in the bag mouth 2, this is torn, and disjunctor has a handle 22 on the diaphragm seal 21, when opening for the first time, firmly mention handle 22, can will tear diaphragm seal 21 and tear off bag mouth 2.Tearing diaphragm seal 21 and both played sealing function, is again a kind of false proof means.On bag mouth 2, be equipped with a lid that can repeat to open and close 3.

As Fig. 2, but described bag mouth 2 and lid 3 have the adhesion portion 4 of a bending, bag mouth 2, lid 3 and to tear diaphragm seal 21 be a disjunctor injection mo(u)lding.Wherein bag mouth 2 is one of a flush fit or interference fit structure with lid 3, reaching sealing function, and don't is subjected to the influence of content product, and this is one of characteristics of this structure maximum.

This packaging bag can be in order to containing various solid-state article, when toing many or too much for use, can repeat to open and close lid and reach and reseal, and protection residue article are difficult for making moist.Packaging bag adds man-hour, can be at bag one side punching in advance one opening, and hot pressing then is compound goes up a bag mouth, and produces by traditional bag flow process and get final product, and the article pack is operated also the same with existing packaging bag.
