Abstract

The utility model discloses a plastic bag, which comprises a bag body and a closed annular string loop. A bag opening is arranged at the upper end of the bag body, folded flanging is arranged at the bag opening of the bag body, the lower edge of the folded flanging is fixedly connected with the bag body, the annular string loop penetrates an interlayer between the folded flanging and the upper end of the bag body, and the interlayer between the folded flanging and the upper end of the bag body comprises two string outlets. When articles are contained in the plastic bag, the bag opening can be contracted by drawing out two ends of the closed annular string loop from the two string outlets respectively, and the drawn string loop can serve as a string for binding the bag opening so that no other strings needs to be prepared. Since the annular string loop penetrates the interlayer between the folded flanging and the upper end of the bag body, when the bag opening is tied up, the string loop cannot slip off and the bag opening can be tied up quite firmly. The interlayer for the string loop to penetrate through is positioned at the upper end of the bag body of the plastic bag, usable space of the plastic bag cannot be wasted by using the string loop to bind the bag opening, and volume utilization rate of the plastic bag is quite high.

Description

A kind of plastic bag

[technical field]

The utility model relates to plastic product, relates in particular to a kind of plastic bag.

[background technology]

Plastic bag majority commonly used is uncovered structure, not only is not easy to tying but also be not easy to carry or carry.The plastic bag of this uncovered structure then pollutes environment as as refuse bag easily; As as storage bag, then be difficult to the internal article of adorning and properly protect.Wanting tying strictly according to the facts; Also need to prepare in addition rope; Because plastic bag sack place is easy to skid, the plastic bag of uncovered structure is difficult to prick very firmly, in order to prick more firmly; The sack rope must stay morely with the upper part, and this can waste many available spaces, plastic bag top again inevitably.

[summary of the invention]

The technical matters that the utility model will solve provides a kind of tying of being convenient to, the plastic bag that capacity utilization is high.

In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is that a kind of plastic bag comprises bag and osed top endless loop; Described bag upper end is provided with sack; Described bag is provided with folding flange at the sack place, and the lower edge of said folding flange is captiveed joint with bag, and described endless loop is through in the interlayer of folding flange and bag upper end; The interlayer position of described folding flange and bag upper end comprises 2 rope outlets.

Described bag comprises antetheca and the rear wall that is superimposed with each other.

Described antetheca and rear wall respectively comprise 1 described rope outlet, and the rope outlet of antetheca and rear wall all is positioned at the middle part of said sack.

Described rope outlet is opened in the upper end at interlayer position, is recessed breach, and front and back are penetrating, expose described endless loop.

The right ends of said endless loop is captiveed joint with bag through bonded structure or thermal welding structure.

Described 2 rope outlets lay respectively at the bag right ends.

The lower edge that described rope outlet extends to folding flange from the upper end at interlayer position is with the lower bag body position.

Width under the described bag closed state is less than the width under the endless loop closed state, under the closed state endless loop be exposed at outside the rope outlet.

Described endless loop is a dicyclo combination fake.

Described endless loop is banded endless loop.

The utility model plastic bag is after installing article; An as long as termination of from 2 rope outlets at interlayer position, extracting the closed ring fake respectively out; Just can the sack of plastic bag be tightened up, the fake of extraction can be used as the rope of tying up sack and uses, and need not to be equipped with in addition rope; The closed ring fake is through between the interlayer on folding flange and the bag, and when tying up sack, fake can slippage, can tie up very firmly; The interlayer that passes fake is positioned at the upper end of plastic bag bag, ties up sack with fake and can not waste available space, plastic bag top, and the capacity utilization of plastic bag is very high.

[specific embodiment]

To the utility model embodiment 1 shown in Figure 3, the plastics storage bag comprises bag 1 and banded osed top endless loop 2 at Fig. 1.

As depicted in figs. 1 and 2, bag 1 comprises antetheca 1a and the rear wall 1b that is superimposed with each other, and bag 1 upper end is a sack, and bag 1 is provided with inwardly folding flange 101 at the sack place, the lower edge and the bag 1 stationary heat welding of folding flange 101,105 of weld bond such as Fig. 2.

Endless loop 2 is through in the interlayer of folding flange 101 and bag 1 upper end.

Folding flange 101 has 2 rope outlets 102 with the interlayer position of bag 1 upper end, and antetheca 1a and rear wall 1b respectively have 1 rope outlet, and 2 rope outlets 102 all are positioned at the middle part of sack.

Rope outlet 102 is opened in the upper end at interlayer position, is recessed semicircle breach, and semi-round rope outlet 102 front and back are penetrating, expose endless loop 2, person's pull fake easy to use.

Endless loop 2 can be movable fully in the interlayer of folding flange 101 and bag 1 upper end, also can fix by at both ends; The right ends of present embodiment endless loop 2 (the c position among Fig. 1) is captiveed joint (also can adopt bonded structure) through the thermal welding structure with bag 1.

As shown in Figure 3; The plastics storage bag is packed into behind the article, the user if a part of from 2 rope outlets 102 at interlayer position, extracting closed ring fake 2 respectively out just can the sack of plastics storage bag be tightened up; The fake of extracting out 2 can be used as the rope of tying up sack and uses, and need not to be equipped with in addition rope; Closed ring fake 2 is through between the interlayer of folding flange 101 and bag 1 upper end, and when tying up sack, fake 2 can slippage, can tie up very firmly; The interlayer that passes fake 2 is positioned at the upper end of plastic bag bag 1, ties up sack with fake 2 and can not waste available space, plastic bag top, and the capacity utilization of plastics storage bag is very high.

The utility model embodiment 2 that Fig. 4 is extremely shown in Figure 6 and the difference of embodiment are that 2 rope outlets 102 lay respectively at the right ends of bag 1 top interlayer.Rope outlet 102 extends to the folding following position of flange 101 lower edges from the upper end at interlayer position always.The width of banded endless loop 2 under closed state is greater than the width of bag 1 under closed state, and endless loop 2 is exposed at outside the rope outlet 102 under the closed state, pull when easy to use.The endless loop 2 and the bag 1 of present embodiment do not have glued construction, are to break away from each other.Simultaneously, the endless loop 2 of present embodiment is dicyclo combination fake, is superimposed together

endless loop

201 and 202 that again can be disconnected from each other during work though dicyclo combination fake comprises at ordinary times.Here, 201 is that outer shroud and 202 is interior ring.

The plastics storage bag of embodiment 2 can be worked as embodiment 1, and is promptly as shown in Figure 3, the

endless loop

201 and 202 of combination carried out pull as 1 endless loop use tie up; Also can and open use in 202 minutes with the endless loop 201 that makes up; Promptly as shown in Figure 6, to a direction pull endless loop 201, to another direction pull endless loop 202; The sack of plastics storage bag is tightened up, and then the exposed parts of fake 201 and 202 band together as rope.
