Abstract

The utility model provides a single - sided opening wrapping bag, by the two plastics faces of front and back and the bag bag body that the bottom surface constituted, just seal on bag body upper portion, has at least a plastics mask to have the transparent window in the bag body. Bag body upper portion is sealed the below and is equipped with unilateral zip fastener, unsmooth strip of paper used for sealing in proper order, the bag bottom surface is integrated into one piece with the plastics face, after the fifty percent discount of the bag bottom surface internal portion of bag of court, and bag body both sides heat -seal formation banding, the inboard of two banding of the bag body is laminating department of bag bottom surface and two plastics faces, and laminating department is triangle -shaped. Unilateral zip fastener is located a plastics face, and just with another plastics face heat -seal, the expansion end of unilateral zip fastener is the stereoplasm head, and the stereoplasm head inlays on the bag body. Unsmooth strip of paper used for sealing is including setting up respectively in sand grip, the groove strip of two plastics faces of the bag body, both agree with for the rectangle or triangle -shaped agree with. The utility model discloses the convenience is torn in whole wrapping bag, and can seal once more, and bag bottom surface laminated structure makes the bag body expand the top to level simultaneously, and the third dimension is strong, clean and tidy, the standard of whole outward appearance around keeping tearing.

Description

A kind of one side opening packaging bag

Technical field

This utility model is related to packing technique field, refers in particular to a kind of one side opening packaging bag.

Background technology

At present, the plastic packaging bag containing strip of paper used for sealing is mostly upper opening, that is, need tear initiation simple tearing notch when opening packaging, Then two bags of faces are separated by both hands, more firmly rip strip of paper used for sealing, take out content.However, this simple tearing notch is easily caused and tears When position sideslip, situations such as cause bag mouth to tear to shreds, operation more bothers, and unsightly.

Content of the invention

The purpose of this utility model is for the existing state of the art, provides a kind of one side opening packaging bag, with monolateral Tear packaging bag mouth, and binding pocket bottom surface bonding structure, so that packaging bag is used and all keep apparent clean and tidy in front and back.

For reaching above-mentioned purpose, this utility model adopts the following technical scheme that

This utility model is a kind of one side opening packaging bag, the bag being made up of in front and back two plastic cover and bag bottom surface, and Bag upper seal, is sequentially provided with single-edge zipper, concavo-convex strip of paper used for sealing, described bag bottom surface and plastic cover below described bag upper seal It is formed in one, towards after the internal doubling of bag, the heat-sealing of bag both sides forms edge sealing, and the inner side of bag two edge sealing is bag bottom for bag bottom surface Face and the joint place of two plastic covers, and joint place is triangular in shape.

In such scheme, single-edge zipper is located on a plastic cover, and seals with another plastic cover.

Further, the movable end of single-edge zipper is hard head, and hard head is embedded on bag.

Further, hard head both sides are protruded.

In such scheme, concavo-convex strip of paper used for sealing includes raised line, the slot stick being respectively arranged at bag two plastic cover.

Further, raised line and slot stick agree with for rectangle or del is agreed with.

Further, in bag, at least one plastic cover has transparent window.

The beneficial effects of the utility model are:

1. monolateral tear, simple to operate, do not destroy packaging bag overall appearance；

2. concavo-convex strip of paper used for sealing makes packaging bag can be again sealed off, and is easy to secondary use；

3. strut that back pkt. bottom is smooth, third dimension is strong；

4. there is transparent window, conveniently check the state of content.

Brief description:

Accompanying drawing 1 is structural representation of the present utility model；

Accompanying drawing 2 is the structural representation of the concavo-convex strip of paper used for sealing of rectangle in this utility model；

Accompanying drawing 3 is the structural representation of the concavo-convex strip of paper used for sealing of del in this utility model.

Specific embodiment:

In order that juror can be further understood that to the purpose of this utility model, feature and function, hereby lift preferably Embodiment simultaneously coordinates schema detailed description as follows:

Refer to shown in Fig. 1, be the structural representation of the preferred embodiment for this utility model, this utility model is one kind One side opening packaging bag, the bag being made up of in front and back two plastic cover 1 and bag bottom surface 2, and bag upper seal, on described bag It is sequentially provided with single-edge zipper 3, concavo-convex strip of paper used for sealing 4, described bag bottom surface 2 and plastic cover 1 are formed in one, bag bottom surface 2 below portion's sealing Towards after the internal doubling of bag, the heat-sealing of bag both sides forms edge sealing 11, and the inner side of bag two edge sealing 11 is bag bottom surface 2 and two plastic covers 1 joint place, and joint place 10 is triangular in shape, after so that bag is strutted, bag bottom surface is in smooth state, and bag is attractive in appearance, and three-dimensional Sense is strong.

Above-mentioned single-edge zipper 3 is located on a plastic cover 1, and seals with another plastic cover 1, and the movable end of single-edge zipper 3 is Hard head 31, and hard head 31 is embedded on bag, hard head 31 both sides are protruded, when tearing single-edge zipper 3, by hard head 31 from bag Eject in body, finger catches the projection of hard head 31, tear toward opposite direction, can be by single-edge zipper 3 from bag after tearing Complete on body to shut down, or be still hung on bag by it.

As shown in Figure 2 and Figure 3, above-mentioned concavo-convex strip of paper used for sealing 4 includes raised line 41, the slot stick being respectively arranged at bag two plastic cover 1 42, raised line 41 agrees with for rectangle with slot stick 42 or del is agreed with, and two ways is nibbling of raised line 41 and slot stick 42 Close structure, raised line 41 can be made to fit with slot stick 42 with handss pressing, again seal bag mouth.

As preferred, in bag, at least one plastic cover 1 has transparent window 12, for coloured plastics material face 1 or there is figure The plastic cover 1 of case, then need reserved transparent window 12, to facilitate the state checking content at any time.

Certainly, only this utility model better embodiment illustrated above, not limits use of the present utility model with this Scope, therefore, every principle in this utility model makes equivalent change and should be included in protection domain of the present utility model.
