Abstract

The utility model relates to an embossed valve bag, which comprises a bag body, wherein the bag body consists of an upper plastic film and a lower plastic film, and the edges of the upper plastic film and the lower plastic film are sealed by heat sealing; a round hole is formed in the middle of one plastic film and close to the top end, and a valve port is mounted on the round hole; embossing is arranged on the plastic film; the embossings are pits which are equally spaced and 0.4-0.5mm deep, and the pits are rhombus; the bottom of the plastic film is in a trapezoid shape; the bag body is a six-edge sealed bag body; the distance from the valve port to the top end of the bag body is 42-47 mm. The utility model discloses need not install the honeycomb duct additional in the bag, can realize that the heat-seal is once accomplished, improve work efficiency. Because the plastic film of the bag body is embossed, uneven textures are formed on the film surface, liquid can circulate at all positions in the bag, a flow guide pipe is not additionally arranged, and the situation that the bag body is punctured by the flow guide pipe before the liquid is contained and in the vacuumizing process is avoided.

Description

Hexagonal-seal embossed valve bag

Technical Field

The utility model relates to a hexagonal seals knurling area valve port bag belongs to wrapping bag technical field.

Background

The existing inner bag of the pressure tank is a bag body with a valve port formed by manually and thermally sealing and installing a five-edge sealing flat bag with a valve port and a flow guide pipe and then thermally sealing and sealing the opening of the bag. The bag is placed in a plastic pressure tank, a valve port is matched with a tank port to contain liquid, gas in the bag is pumped out through the valve port before the liquid is contained, meanwhile, the gas is filled between the pressure tank and an inner bag, then, the liquid with pressure is injected through the valve port, the bag body is easy to puncture the inner bag through a flow guide pipe due to the existence of the flow guide pipe in the bag during the vacuumizing process, and after the conventional six-edge sealed inner bag is filled with pressurized liquid, the bag body is easy to adhere to the tank body due to pressure when the liquid is discharged, so that the liquid is difficult to empty and drain to the greatest extent and remains in the bag, therefore, anti-sticking gloss oil needs to be coated on the surface of the inner bag, the adhesion between the bag body and the tank body is reduced, and the liquid in the bag is reduced in residue. In addition, the conventional plastic valve bag has hard stiffness and texture, and is provided with a long flow guide pipe, so that the conventional plastic valve bag is difficult to be arranged in a pressure tank, and the working efficiency is influenced.

Disclosure of Invention

An object of the utility model is to overcome the not enough of existence among the prior art, provide an emboss area valve port bag, its materials and the processing of having simplified the bag body have reduced the damage in the use, and the water conservancy diversion performance of the bag body is good, and anti-adhesion performance is good, and the compliance is good, and it is more convenient to pack.

According to the utility model provides a technical scheme: an embossed valved bag, which comprises a bag body, wherein the bag body consists of an upper plastic film and a lower plastic film, and the edges of the upper plastic film and the lower plastic film are sealed by heat sealing; a round hole is formed in the middle of one plastic film and close to the top end, and a valve port is mounted on the round hole; embossing is arranged on the plastic film.

Further, the embossings are pits that are equally spaced and 0.4-0.5mm deep.

Further, the pits are rhombus-shaped.

Further, the bottom of the plastic film is trapezoidal.

Further, the bag body is a six-edge sealed bag body.

Further, the distance from the valve port to the top end of the bag body is 42-47 mm.

Furthermore, the plastic film is a high-barrier plastic co-extrusion film, and the valve port is made of plastic.

Compared with the prior art, the utility model, have following advantage:

the utility model discloses need not install the honeycomb duct additional in the bag, can realize that the heat-seal is once accomplished, improve work efficiency. Because the plastic film of the bag body is embossed, uneven textures are formed on the film surface, liquid can circulate at all positions in the bag, a flow guide pipe is not additionally arranged, and the situation that the bag body is punctured by the flow guide pipe before the liquid is contained and in the vacuumizing process is avoided. Because the film is embossed and has bulges on the surface, the bag body can not be completely attached to the tank body after liquid with pressure is injected into the bag, and the bag body can not be adhered to the tank body when the liquid is discharged, thereby being beneficial to draining the liquid, not leaving residual liquid and not needing to coat anti-sticking gloss oil on the surface of the bag. The film through the impressed watermark processing, its feel and deflection all can become soft, are changeing when packing into jar body and get into, can improve work efficiency for it is more convenient to pack.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the embossed valved bag comprises a six-edge bag body, wherein the bag body is composed of an upper plastic film 1 and a lower plastic film 1, and the edges of the upper plastic film 1 and the lower plastic film 1 are sealed by heat sealing; a round hole is formed in the middle of one plastic film 1 close to the top end, and as shown in fig. 2, a valve port 2 is installed on the round hole; embossing is arranged on the plastic film 1.

As shown in fig. 3, the embossings are diamond-shaped dimples equally spaced about 0.5mm deep.

The bottom of the plastic film 1 is in a trapezoid shape.

Preferably, the distance from the valve port 2 to the top end of the bag body is 45 mm.

The utility model relates to an emboss and take valve port bag, it includes the bag body, the bag body is by two upper and lower rectangles through embossing processed's plastic film 1, the right angle that bag body bottom cut and get rid of two limits is trapezoidal, opens a round hole in one of them slice film apart from the middle of 45mm departments of sack, including valve port 2, earlier heat seal valve port 2 is six banding of heat seal again, forms the heat seal banding with two plastic film bonds, can accomplish emboss and take valve port inner bag.

The embossing treatment adopted on the film used by the bag body is to press rhombic small pits with equal intervals of about 0.5mm in depth on the film, so that the surface of the film has obvious concave-convex feeling. Referring to fig. 3, before containing articles, in the process of vacuumizing and discharging after canning liquid, when the embossed film is used as a bag body and two films are attached together, all parts of the two films are connected through micropores due to embossing, and the bag has good flow conductivity. And can ensure the bag body to be firm and not easy to be damaged.

The utility model discloses the bag body, after pouring into and take pressure liquid, because the bag body adopts the impressed watermark film, there is obvious arch on the bag body surface, makes the difficult adhesion of the bag body and jar body, can not cause bag interior liquid to remain because of the bag body adhesion on jar body when liquid discharge.

The utility model discloses the bag body, the jar body in-process of packing into before the use, use the impressed watermark film because of the bag body, make the stiffness of material and feel soft, change the jar body of packing into, it is more convenient to operate, and work efficiency is higher.

It is to be understood that the above embodiments are merely exemplary embodiments that have been employed to illustrate the principles of the present invention, and that the present invention is not limited thereto. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit and substance of the invention, and these modifications and improvements are also considered to be within the scope of the invention.
