Abstract

The utility model discloses a novel packing bag, which comprises a sheet body I, a sheet body II and a first joint portion. Two lateral edges of the two sheet bodies are jointed oppositely, and the first joint portion is jointed corresponding to bottom edges and lateral edges of the two sheet bodies and is folded into the bag body. The novel packing bag further comprises a second joint portion, both top edges of the sheet body I and the sheet body II extend upwardly to form extending portions without being jointed, two opposite lateral edges of the second joint portion are respectively jointed with lateral edges of the extending portions of the sheet body I and the sheet body II, the top edge of the second joint portion is jointed with the top edge of the extending portion of the sheet body I, the bottom edge of the second joint portion is locked with the top edge of the extending portion of the sheet body II by utilizing a locking part, and the second joint portion is folded into the bag body. The novel packing bag is low in volume and large in containing space, and prolongs service life because the locking part is not easy to be damaged.

Description

A kind of novel package bag

Technical field

The utility model relates to a kind of packaging bag.

Background technology

The kind of fresh-keeping foodstuff is more and more at present, in the process of preservation, transportation, packaging bag is an indispensable part, present packaging bag mostly comprises two

lamellar bodies

10,20, with reference to shown in Figure 1, fitted mutually in the edge on its three limits respectively again and form, and the one side of will not fit is as sack 30, and use fastening such as slide fastener, article to be packaged are put into packaging bag by sack 30, yet, because the general volume of products to be packaged is bigger, space in the bag is strutted very big, easily closures such as slide fastener are damaged.

Therefore, there was a kind of package construction to produce afterwards again, with reference to shown in Figure 2, it is to set up a junction surface 60 in addition in the bottom of two lamellar bodies 40,50, relative two limits at this junction surface 60 are bonding with the bottom of lamellar body 40,50 respectively, and the two other limit is corresponding bonding with the side of lamellar body 40,50, when not using, junction surface 60 is folded to packaging bag inside, to reduce volume, saving takes up room, and when being placed into article, junction surface 60 is launched, increase accommodation space.

Yet aforementioned structure is when containing article, because the sack of packaging bag still only uses a slide fastener sealed, sealed power is bigger, when article in the bag are big, still easily slide fastener is stretched and damages to both sides, so this structure still are further improved.

In view of above-mentioned analysis, the design people studies improvement at present package construction, and this case produces thus.

The utility model content

Main purpose of the present utility model is to provide a kind of novel package bag, and its volume is little, and the splendid attire space is big, and closure is not fragile, increases the service life.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of novel package bag comprises lamellar body one, lamellar body two and first junction surface, and the dual-side of two lamellar bodies is fitted relatively, and the base of corresponding two lamellar bodies in first junction surface and side are fitted also folding in bag; Also comprise second junction surface, lamellar body one all extends upward the extension that formation is not fitted with the top margin of lamellar body two, and fit with the side of lamellar body one, lamellar body two extensions respectively in the limit, two opposite sides at second junction surface, and the top margin of top margin and lamellar body one extension is fitted, and the top margin of base and lamellar body two extensions utilizes closure sealed, and this second junction surface folding is in bag.

Above-mentioned closure is a slide fastener.

The top margin of above-mentioned lamellar body one extension also extends upward and forms portable district, and is provided with for portable grip part.

All be formed with air extractor vent on above-mentioned lamellar body one and the lamellar body two.

After adopting such scheme, the utility model extends upward the formation extension by the sack at the lamellar body one, two that has packaging bag now, and the side of another second junction surface and two extensions fitted, when in the packaging bag during article-containing, all launch at first and second junction surface, makes packaging bag form a kind of three-dimensional casing form, and the bag inner volume increases greatly, reduce the tensile force of article, prolong the service life of closure closure; And when article-containing not, first and second junction surface folding in bag,

Description of drawings

Fig. 2 is the schematic perspective view of another kind of existing packaging bag;

Scheme drawing when Fig. 3 is the utility model article-containing.

The specific embodiment

Below in conjunction with drawings and the specific embodiments the utility model is elaborated.

With reference to shown in Figure 3, be the structural representation of a kind of novel package bag of the utility model, it comprises lamellar body 1, lamellar body 22, first junction surface 3 and second junction surface 4.

Two relative applyings of side of lamellar body 1 and lamellar body 22, and all extend upward the extension 11,21 that formation does not fit in the top margin position.

The base of first junction surface, 3 corresponding lamellar bodies 1, lamellar body 22 and dual-side are fitted, and folding is identical with existing structure herein in bag, so repeat no more.

4 foldings of second junction surface are in bag, and specifically, the corresponding respectively side with extension 11,21 of its two sides is fitted, and the top margin of top margin and extension 11 is fitted, and the top margin of base and extension 21 utilizes closure sealed, and in the present embodiment, closure uses slide fastener 5.

When the utility model uses, when need article-containing 6, article 6 are put into bag by sack, and tighten up slide fastener 5, and this moment, article 6 were full with bag, and first junction surface 3 transfers expansion to by folding state, increase space in the bag, simultaneously, also launch at second junction surface 4, make the utility model become a kind of three-dimensional contouring of cuboid, easy to use, simultaneously owing to the splendid attire space increases, thereby the tensile force of 6 pairs of slide fasteners 5 of article reduces, make slide fastener 5 not fragile, increase the service life; And after taking out article 6, can be conveniently with first junction surface 3 and 4 foldings of second junction surface in bag, reduce volume, do not increase than existing structure and take up room, convenient retracted.

Carry for convenience and carrying, present embodiment also extends upward at the top margin of the extension 11 of lamellar body 1 and forms portable district 12, and the stage casing in this portable district 12 is provided with grip part 13, and the user can conveniently pass grip part 13 with hand and carry and carrying.

In the present embodiment, also be formed with air extractor vent 14 respectively on lamellar body 1 and the lamellar body 22, when article-containing 6, utilize two air extractor vents 14 to carry out air inerchange with the external world.

In sum, a kind of novel package bag of the utility model, focus on extending upward and form extension 11,21 at lamellar body one, 21,2 top margin, and at this extension 11,21 second junction surface 4 of fitting, and use slide fastener 5 that second junction surface 4 is sealed with extension 21, when containing article 6, all launch at first junction surface 3 and second junction surface 4, increases the splendid attire space of packaging bag, and the tensile force of 6 pairs of slide fasteners 5 of article reduces greatly, make slide fastener 5 not fragile, prolong its service life; And when not in use, first junction surface 3 and second junction surface 4 can be folded the back foldings in bag, and it is little to take up room, and volume is little.

Above embodiment only is explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every according to the technological thought that the utility model proposes, any change of being done on the technical scheme basis all falls within the utility model protection domain.
