CN202743714U - Square-bottom and high-capacity vacuum compression bag - Google Patents

Abstract

A square-bottom and high-capacity vacuum compression bag comprises a bag body, a bag bottom and a bag opening which are all made of plastic films; a sealing buckle is installed in the bag opening; the bag body is provided with an air extraction valve therein; the square-bottom and high-capacity vacuum compression bag is characterized in that the bag bottom includes a rectangular plastic film bottom piece; the rectangular plastic film bottom piece and the bag body are produced to the square bag bottom by four welding edges including a left welding edge, a right welding edge, a front welding edge and a back welding edge. The bag bottom is welded with one rectangular plastic film bottom piece, so that the bag bottom is formed in a rectangle, the volume is largely increased compared with the volume of a flat bag bottom in the prior art, and more goods can be stored; and if the compression bag is put in a sorting box, the space of the sorting box is reasonably used to reduce waste.

Description

Side's end high-capacity vacuum compressed bag

Technical field

The utility model relates to vacuum compression bag, and the end, the side of relating to high-capacity vacuum compressed bag particularly is main and box is supporting.

Background technology

The textile products such as bedding and clothing are put into plastic film bag, use again the pump extracting air, make that object is subjected to vacuum compression in the bag, reduce volume, save taking up room of storage, but existing vacuum compression bag is that plastic sheeting is made pancake, described pancake is that the both sides of two blocks of plastic sheetings are weldingly connected, bottom welding links to each other, and sack is installed seal buckle; Also can adopt the cylindrical plastic film, the bottom welding sealing, sack is installed seal buckle, after quilt, clothes etc. were put into compressed bag, expanded at the middle part, but two is flat, the goods of putting is few, put into box if vacuum compression bag is filled goods, larger space is kept at two of box, causes waste.

Summary of the invention

The purpose of this utility model is the shortcoming that exists in order to overcome prior art, provides a kind of holding freight many, reduces the space, the high-capacity vacuum compressed bag of the square end of being fully used after particularly putting into box.

The end, the utility model side technical scheme of high-capacity vacuum compressed bag is: comprise bag, the bag end and sack that plastic sheeting is made, sack is installed seal buckle, extraction valve is installed in bag, it is characterized in that described bag comprises rectangular plastic sheeting egative film in the end, rectangular plastic sheeting egative film and bag have left toe, backhand welding limit, front toe and rear toe totally 4 toes make the square bag of end.

The utility model discloses high-capacity vacuum compressed bag at the bottom of a kind of side, at the bottom of bag welding-on a rectangular plastic sheeting egative film, rectangularity at the bottom of making bag, greatly increase with phase specific volume at the bottom of the flat bag of prior art, the goods of putting is many, if put into box, the space of box is rationally utilized, cut the waste.

The end, the utility model side high-capacity vacuum compressed bag has 4 bevel welding wiring between described left and right toe and the forward and backward toe.In use the bottom is strutted, left and right toe is folding to the centre through the bevel welding wiring.

Fig. 1 is that the end, the utility model side master of high-capacity vacuum compressed bag looks scheme drawing;

The elevational schematic view of Fig. 2 side of being end high-capacity vacuum compressed bag semi-collapsed condition;

Fig. 3 is the A-A direction schematic cross-section of Fig. 1;

Fig. 4 side of being end high-capacity vacuum compressed bag is used the elevational schematic view of state;

Fig. 5 be bag at the bottom of the deployed condition elevational schematic view.

The specific embodiment

The utility model relates to high-capacity vacuum compressed bag at the bottom of a kind of side, such as Fig. 1-shown in Figure 5, comprise bag 1, the bag end 2 and sack 3 that plastic sheeting is made, sack is installed seal buckle 31, extraction valve 4 is installed in bag, it is characterized in that described bag comprises rectangular plastic sheeting egative film 5 in the end 2, rectangular plastic sheeting egative film 5 and bag have left toe 51, backhand welding limit 52, front toe 53 and rear toe 54 totally 4 toes make the square bag end.At the bottom of bag 2 welding-ons a rectangular plastic sheeting egative film 5, rectangularity at the bottom of making bag increases greatly with phase specific volume at the bottom of the flat bag of prior art, the goods of putting is many, if put into box, the space of box is rationally utilized, and cuts the waste.Described left and right toe 51,52 and forward and backward toe 53,54 between 4 bevel welding wiring 55 are arranged.In use the bottom is strutted, left and right toe 51,52 folds to the centre through bevel welding wiring 55.

Claims (2)

1. The side end high-capacity vacuum compressed bag, comprise bag (1), the bag end (2) and sack (3) that plastic sheeting is made, sack is installed seal buckle (31), extraction valve (4) is installed in bag, it is characterized in that the described bag end (2) comprises rectangular plastic sheeting egative film (5), rectangular plastic sheeting egative film (5) and bag have left toe (51), backhand welding limit (52), front toe (53) and rear toe (54) totally 4 toes make the square bag of end.
2. 2. high-capacity vacuum compressed bag at the bottom of the side as claimed in claim 1 is characterized in that between described left and right toe (51,52) and the forward and backward toe (53,54) 4 bevel welding wiring (55) being arranged.
