Abstract

A vacuum compression bag comprises a bag. The bag comprises bag surfaces which are peripherally hermetically combined with each other, an opening is arranged on the bag, a sealing component is arranged at the opening, a vacuum pumping nozzle is further arranged on the bag, and inner surfaces of the bag surfaces are concave-convex surfaces. The vacuum compression bag has the advantages that inner surfaces of the bag are rough contact surfaces instead of conventional smooth contact surfaces owing to the concave-convex surfaces, so that the rough inner surfaces can be in sufficient contact with articles in the bag during pumping, and air can be exhausted conveniently and can be pumped down conveniently and thoroughly; and the inner surfaces, which are in contact with the articles in the bag, of the bag are not easy to slip, the bag opening is prevented from loosening due to slipping of the bag surfaces, accordingly, air leakage is prevented, and the vacuum compression bag can be sealed advantageously when the articles are stored.

Description

A kind of vacuum compression bag

Technical field

The utility model relates to vacuum compression bag.

Background technology

Vacuum compression bag is one of common article-storage device, both can compressed bag in the volume of article, be convenient to deposit, and the article of preserving with vacuum bag are difficult for going mouldy.When vacuum compression bag uses, earlier article are put into bag, the sack sealing, then with air extractor with air extraction in the bag, wherein, the committed step that deflates and be to use, existing vacuum bag often improves the vacuum performance of vacuum compression bag from the seal aspect of the structure of the mouth of bleeding and sack.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of vacuum compression bag, improves the vacuum seal performance of vacuum compression bag from bag face structure.

The technical scheme that the utility model technical solution problem is adopted is: a kind of vacuum compression bag, comprise bag, and bag is made up of the bag face of the mutual driving fit of periphery, opening is set on the bag, opening part is provided with sealing element, also is provided with vacuum exhaust nozzle on the bag, and the inner surface of bag face is a male and fomale(M﹠F).Male and fomale(M﹠F) makes the bag inside face become coarse contact surface by common smooth contact surface, and when bleeding, coarse inside face can contact with article in the bag better, is convenient to the discharge of air.

When adopting technique scheme, further technical scheme below the utility model can also adopt or make up and adopt:

Have a plurality of projectioies on the inner surface of bag face, a plurality of projectioies make bag face inner surface become male and fomale(M﹠F).

A plurality of projectioies evenly or unevenly are distributed on the inner surface of bag face.

The bag face is a plastic film layers.Sealing element is the self-locking slide fastener.

Technique effect of the present utility model is: the bag inside face is designed to male and fomale(M﹠F), when coarse inside face carries out air extracting seal after pack, can contacts with article in the bag better, be convenient to the discharge of air, make bleed more convenient more thorough; Deposit or handling process in, contacting of article be difficult for to be slided in bag inside face and the bag, avoided loosening gas leakage of sack of sliding and causing because of the bag face, helps depositing the sealing in the process.

Description of drawings

Fig. 1 is the overall schematic of compressed bag of the present utility model.

Fig. 2 is the cross section enlarged drawing at A position among Fig. 1.

The specific embodiment

With reference to accompanying drawing 1,2.The utility model comprises bag 1, and bag 1 is made up of the bag face 2 of the mutual driving fit of periphery, and bag face 2 can adopt plastic film layers.Opening 3 is set on the bag 1, and opening 3 places are provided with sealing element 4, and sealing element 4 can adopt the self-locking slide fastener.Also be provided with vacuum exhaust nozzle 5 on the bag 1, have a plurality of protruding 21 on the inner surface of bag face 2, projection 21 makes the inside face of bag faces 2 form male and fomale(M﹠F), and projection 21 can be distributed in and form latticedly on the inner surface of bag face 2, and projection 21 also can be arranged on the surface of bag face 2 brokenly.

During use, article are put into bag 1 from opening 3, the self-locking slide fastener closes, air in the bag is taken out to the greatest extent from vacuum exhaust nozzle 5 by air extracting pump, the slit that forms between the projection 21 of bag inside face helps the discharge of bag interior air, bleed finish after, article fit tightly in bag inside face and the bag, be difficult for to slide.
