Description

Double-deck valve bag

Technical field

The utility model relates to a kind of sealing bag, and particularly a kind of valve bag, is applied to deposit and record article.

Background technology

Valve bag be a kind of need not be by the packaging bag of any instrument sealing, common have clip chain valve bag, a non-drying glue valve bag etc.In daily life, valve bag can be used for taking in msp, as nut, nail, plays anti-corrosion effect; With the valve bag that food grade materials is made, can be used for storing tea, dry fruit, rice, also can deposit frozen food, avoid moisture absorption, taint of odour; Books, clothing can also be put into wherein and preserve, there is the advantages such as protection against the tide, insect protected, also reusable.Meanwhile, valve bag is also widely used in laboratory sampling, Sample storage, transportation, has made up that rigid container weight is large, large, frangible, not portative shortcoming takes up room.

But; owing to being contained in the article of valve bag the inside, often need long preservation; particularly laboratory sample often can be preserved or long-distance transportation under the environment of low temperature, humidity; therefore, in storage and transport process, be easy to cause the loss of Item Information, cause inconvenience; as deposit food in bulk and but do not record the information such as date manufactured; particularly deposit laboratory sample, once lose the record of sampling situation and sample transportation preservation situation, sample will lose value.

Conventionally, label paper is sticked on to valve bag surface and write, or directly on valve bag, write to record Item Information with marker.But because bag softness is easy to break, plucking on valve bag labels easily comes off, and label usable area is little, cannot record in detail Item Information; And marker person's handwriting easily comes off in the environment of low temperature, humidity, and above two kinds of contents that method is write are difficult to erase, and affect valve bag repeated usage.

Utility model content

The purpose of this utility model is to have overcome the deficiencies in the prior art, provide a kind of double-deck valve bag except bag itself, also have the outer bag that can deposit a small amount of article, on Item Information can being write on, folding being put in outer bag, also other article of needs can be put in outer bag, preserve with together with article in valve bag, transportation, can not lose, simple in structure, convenient and practical.

For reaching foregoing invention, create object, the technical solution adopted in the utility model is as follows:

A kind of double-deck valve bag, comprise the bag being formed by upper and lower two layers of plastic film and the sealing line that is positioned at sack, on the plastic film outside face of the upper strata of bag, also increase one deck additional plastic film is set, the size of additional plastic film is not more than the size of the upper strata plastic film of bag, make together with the edge of additional plastic film is heat sealing at the upper strata of bag plastic film, on additional plastic film, to offer for picking and placeing the opening of label information material or little article, in the outside of bag, form the outer bag of middle opening.

As the preferred technical scheme of the present invention, the opening on additional plastic film is straight line opening.

As the further preferred technical scheme of the present invention, the aperture lines on additional plastic film approaches parallel with sealing line.

As the improvement of technique scheme, the opening part on additional plastic film is provided with adhesive tape, and adhesive tape can be pasted opening to seal.

The utility model compared with prior art, has following substantive distinguishing features and advantage:

1. the utility model simplicity of design, does not introduce loaded down with trivial details new process, is easy to make, and is applicable to printing;

2. the double-deck valve bag outer bag of the utility model opening is in centre, and folding with convenience, packs the middle-sized article such as paper into and be difficult for dropping out, as fills little article and need sealing, and available adhesive tape opening part is pasted sealing;

3. when the double-deck valve bag of the utility model is used in routine use or laboratory, the details of in-built article can be write on paper, be put in outer bag, avoid Item Information to lose.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment pair of lamina valve bag.

Fig. 2 be in Fig. 1 A to multiview drawing.

The specific embodiment

Preferred embodiment accompanying drawings of the present utility model is as follows:

embodiment mono-:

In the present embodiment, referring to Fig. 1 and Fig. 2, a kind of double-deck valve bag, comprise the bag 1 being formed by upper and lower two layers of plastic film and the sealing line 3 that is positioned at sack 2, on the plastic film outside face of the upper strata of bag 1, also increase one deck additional plastic film 4 is set, the size of additional plastic film 4 is not more than the size of the upper strata plastic film of bag 1, make together with the edge of additional plastic film 4 is heat sealing at the upper strata of bag 1 plastic film, on additional plastic film 4, offer for picking and placeing the opening 5 of label information material or little article, opening 5 on additional plastic film 4 is straight line opening, opening 5 lines on additional plastic film 4 are parallel with sealing line 3, in the outside of bag 1, form the outer bag 6 of middle opening.The present embodiment valve bag is double-decker, when article are put into valve bag, detailed Item Information material or other article that need to preserve together with article in valve bag can be put in outer bag 6, avoids losing.

embodiment bis-:

The present embodiment and embodiment mono-are basic identical, and special feature is:

In the present embodiment, opening 5 places on additional plastic film 4 are provided with adhesive tape, and adhesive tape can be pasted opening 5 to seal, and is adapted at packing small article or label in outer bag 6, avoid small article or label to lose from outer bag 6 and fall to losing.
