A kind of self-expanding plastics bag with square bottom, including the square tube shape bag body enclosed by upper bottom surface and four side walls, sealing surface is provided with the upper bottom surface parallel beneath of bag body, sealing surface and four side walls are tightly connected and form Sealed sandwich, on four inclines of bag body four pipes are connected with along the length direction of incline, the upper end of four pipes is connected with Sealed sandwich and lower end seals, and charging valve is left in the lower end of a pipe.The bag with square bottom itself can expand sizing, be easy to be set with, and be more convenient for coordinating mounting bracket to use, and suit is quickly, it is not easy to is scratched.

Description

A kind of self-expanding plastics bag with square bottom

Technical field

A kind of bag with square bottom is the utility model is related to, itself can be expanded in particular to one kind, be easy to rapid deployment to make Bag with square bottom.

Background technology

Bag with square bottom refers generally to the polybag that bottom is square, paper bag etc., has four side walls, and overall is in square tube shape, for The people of bag with square bottom one of stock size can flexibly control, very easy to use.But for large-sized bag with square bottom, it is grown Degree exceeds people's height, and width exceedes the brachium of human body two, generally requires several individuals and strutted, be then enclosed on the equipment to be packed etc. On object, it is more inconvenient to use.Especially with plastics bag with square bottom pack square objects when, because plastics soft, itself not It can be molded, in several personal stay bolt baggings, bag body is easily scratched by object corner angle.

Utility model content

The purpose of this utility model is to provide a kind of self-expanding plastics bag with square bottom, and the bag with square bottom itself can expand sizing, It is easy to be set with, is more convenient for coordinating mounting bracket to use, suit is quick, it is not easy to is scratched.

To achieve the above object, the utility model takes following technical scheme：

A kind of self-expanding plastics bag with square bottom, including the square tube shape bag body enclosed by upper bottom surface and four side walls, it is special Sign is, is provided with sealing surface in the upper bottom surface parallel beneath of bag body, the sealing surface is tightly connected and formed close with four side walls Binder layer, four pipes are connected with along the length direction of incline on four inclines of bag body, the upper end of four pipes with Sealed sandwich is connected and lower end seals, and charging valve is left in the lower end of a pipe.

Preferably, a handle is each provided with four sides top and bottom of the bag body, the handle is connected to In the side wall.

Preferably, the handle has inner sealing air, the sealing space and the pipe phase on the rib of the bag side Connection.

In above-mentioned technical proposal, inflated by charging valve to the pipe on bag body and Sealed sandwich, upper bottom surface can be made Expansion is unfolded, and makes four side wall extending longitudinallies after four pipe inflations, so whole bag body can be fully deployed.In suit, no It can scrape pulling because of plastics soft and packing material and scratch packaging bag.Handle can also inflation, can so be led to special stand Cross handle bag with square bottom is enclosed on object, save manually, improve operating efficiency, more effectively prevent a bag body breakage.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the utility model cross section structure diagram.

Embodiment

Below in conjunction with the accompanying drawings, the utility model is described further：

As depicted in figs. 1 and 2, this self-expanding plastics bag with square bottom has what is enclosed by upper bottom surface 1 and four side walls 2 Square tube shape bag body, sealing surface 6 is provided with the parallel beneath of upper bottom surface 1 of bag body, sealing surface 6 and four side walls 2 are sealedly connected on one Rise, four side walls 2 of sealing surface 6, upper bottom surface 1 and surrounding, which are surrounded, forms a Sealed sandwich 7, and air is filled with the Sealed sandwich After can expand, bag body is strutted in the horizontal direction.It is also integrally formed on four inclines of bag body to be formed with four Pipe 3, every pipe 3 all stretches along the length direction of incline, and upper port 8 is connected with Sealed sandwich 7, lower end sealing. Charging valve 5 is equipped with wherein on a pipe 3, is made up of plastic wrapper and plastic plug, plastic wrapper is connected with pipe 3, from filling Air valve 5 is inflated to pipe 3, and sealed interlayer 7 can be filled with other three pipes, can be bag body after pipe inflation In the vertical direction struts.After strutting, it is easy to worker to be set with, breakage bag body will not be drawn.

After bag body is strutted by expansion, also premise is provided to carry out suit using instrument.Only need to be in the side wall of bag body Lower both ends connect handle 4, in order that fluffy of handle is easy to be caught by support instrument, handle can be made into air bag, made inside it With sealing space, and the seal gas is connected with pipe 3, and connection handle is inflated together when so inflating.Use timberer Tool suit, it can both save manually, raising operating efficiency, more can effectively prevent a bag body breakage.

The present embodiment is the explanation conceived to the utility model and realized, is not limited, in this reality With under new design, without the technical scheme that substantially converts still in protection domain.
