Abstract

The utility model relates to a structure of a packaging bag, which comprises a bag body with an internal containing space. An opening of the bag body is provided with two sealing trim strips at interval; the sealing trim strips consist of ledges and grooves, which are embedded correspondingly, and respectively and fixedly arranged at the inner surface of the opening of the bag body, and penetrate through two ends of the bag body horizontally. Due to the structure, the packaging bag has double-layer sealing protective performance, and has better sealing property.

Description

Package construction

Technical field

The utility model is relevant for a kind of package construction.

Background technology

The field that packaging bag is used is comparatively extensive and pattern is numerous, all be by two involutory bonding bags that form tool middle part accommodation space of plastic film up and down substantially, its encapsulating method is to adopt to take out in the bag gas after weighting material is packed bag into to carry out heat seal more bonding, form the leak free bag, but this packaging bag can only disposablely be used, comparatively inconvenience, and cause waste, not environmental protection; Afterwards, a kind of packaging bag with sealing strip occurred, its structure is one seal trim strip of opening part setting at bag, make sack repeatably open, seal, the weighting material that can not once use up can remake sealing and preserve, and is easy to use, but deficiency is, the sealing press strip is difficult for pressing accurate in the use, when particularly in bag, gas being arranged, make the press strip semistall easily, cause gas leakage, sealing effectiveness is not good, and further improved necessity is arranged in fact.

The utility model content

Therefore, the purpose of this utility model is to provide a kind of package construction that can effectively guarantee leak tightness.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is:

A kind of package construction, the bag that comprises the inner accommodation space of a tool, the two seals press strip is set at interval on the sack of this bag, and the sealing press strip is by forming by corresponding chimeric fin and groove, and it is surperficial and laterally run through the two ends of sack to be fixedly arranged on the internal layer of this bag sack respectively.

The inside folding in the bottom of this bag forms a folding part.

One of compacting runs through the some broken string at sack two ends above this bag two seals press strip.

On the outside face of this bag, indicate scale value.

After adopting such scheme; owing on the sack of bag, be arranged at intervals with the two seals press strip; therefore make packaging bag of the present utility model have double-ply seal protection performance; leak tightness is better; therein one seal trim strip destroyed after, also can rely on another road seal trim strip to seal, still can keep the leak tightness of packaging bag; therefore the utility model is widely used, can be in order to pack various solids, liquid or powder etc.

The specific embodiment

Extremely shown in Figure 5 as Fig. 1, be a kind of package construction of the present utility model, the bag 1 that comprises the inner accommodation space 11 of a tool, two seals press strip 2 is set on the sack of this bag 1 at interval, sealing press strip 2 is by forming with groove 22 by corresponding chimeric fin 21, and it is surperficial and laterally run through the two ends of sack to be fixedly arranged on the internal layer of this bag 1 sack respectively, and the fin 21 of sealing press strip 2 and groove 22 are can be corresponding chimeric or separate, make sack repeatably open, seal, the convenient use; And the inside folding in the bottom of this bag 1 forms a folding part 12, at the bottom of the bottom that makes bag 1 after strutting is the horizontal bag, uses the capacity that can increase the bag accommodation space.

As seen, said structure is adopted in packaging bag of the present utility model, has the double-ply sealing property, leak tightness is better, and wherein one seal trim strip if after destroyed, also can rely on another road seal trim strip to seal, the leak tightness that still can keep packaging bag, therefore the utility model is widely used, can be in order to pack various solids, liquid or powder etc., and the utility model also can indicate scale value 13 on the outside face of packaging bag bag, for splendid attire in the bag be liquid substance the time, what of bag interior ccontaining liquid the user can intuitively measure with reference to the scale value on the bag, provides bag many additional functioies easily.

In addition, the utility model is also suppressed a some broken string 14 that runs through the sack two ends as sealing off marks above above-mentioned bag 1 two seals press strip 2, open the package first and need tear off putting the outer part of broken string earlier, just can open seal trim strip 2, therefore, can whether have to judge whether this packaging bag was opened according to the part beyond this some broken string, to make things convenient for the user.

Claims

1. package construction, the bag that comprises the inner accommodation space of a tool, it is characterized in that: the two seals press strip is set on the sack of this bag at interval, the sealing press strip is by forming by corresponding chimeric fin and groove, and it is surperficial and laterally run through the two ends of sack to be fixedly arranged on the internal layer of this bag sack respectively.
