Abstract

The utility model relates to a packaging bag, in particular to a cement packaging bag. The utility model provides the following technical proposal that a cement packaging bag comprises a bag body; a valve port is arranged on the upper part of the bag body; the valve port can be folded towards the inner cavity of the bag body; the valve port opening is communicated with the inner cavity of the bag body, and the openings on both ends of the bag body are provided with sewing lines; the bag body is rectangle, and the corner position on one end of the bag body is provided with an extension block which is the valve port. Based on the technical proposal, the utility model provides a cement packaging bag which has convenient machining and high strength.

Description

Cement package bags

Technical field

The utility model relates to a kind of packaging bag, particularly a kind of cement package bags.

Background technology

Cement package bags is because when cement injection, need bear the weight of certain temperature, pressure and cement, when therefore making finished product, place, the bag limit flanging that cement package bags need be had valve port, (promptly be converted into right-angled trapezium to the bag inner chamber, its valve port opening is communicated with the bag inner chamber), with special suture sealing, just can meet the requirement of cement packing industry.

The valve port place of the cement package bags that is occurred on existing market and the data all needs protruding material, should fold to the bag inner chamber by protruding material then, makes it form valve port; Yet add at present all to adopt man-hour a protruding material is made at the valve port place of cement package bags, expended time in like this and operation, improved the productive costs of manufacturer undoubtedly.

Summary of the invention

At the deficiency that prior art exists, the utility model provides a kind of cement package bags easy to process, high-intensity.

For achieving the above object, the utility model provides following technical scheme: a kind of cement package bags, include bag, described bag be provided with valve port, this valve port is folding to the bag inner chamber, the valve port opening is communicated with the bag inner chamber, and the both ends open of bag is provided with the sealing line, described bag is rectangular, and the edge of one end is provided with extension block, and this extension block is a valve port.

Bag is rectangular in this, and the edge of one end is provided with extension block, and this extension block is a valve port, promptly embody the part that valve port is a bag after being provided with like this, valve port and bag are wholely set, and have reduced the manufacturing procedure when making cement package bags like this, have reduced productive costs.

The utility model further is set to: described extension block is located at the edge on bag top, and extension block is a rectangle.

Extension block is a rectangle in this, and it is folding for convenience being provided with like this.

The utility model further is set to: an end face of described bag is provided with strengthening membrane, and described strengthening membrane is provided with a plurality of breather holes.

End face of bag is provided with strengthening membrane in this, and setting can be strengthened the intensity of cement package bags like this, makes it can bear bigger load, and it then is in order to make bag can keep ventilative that strengthening membrane is provided with a plurality of breather holes.

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

Fig. 1 is the block diagram of the utility model embodiment;

Fig. 2 is the structural representation of the utility model embodiment;

Fig. 3 is the A-A cutaway view of Fig. 2;

Fig. 4 is the I portion enlarged drawing of Fig. 3.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, a kind of cement package bags shown in Figure 4, include bag 1, described bag 1 be provided with valve port, this valve port is folding to bag 1 inner chamber 11, the valve port opening is communicated with bag 1 inner chamber 11, and the both ends open of bag 1 is provided with sealing line 2, and described bag 1 is rectangular, the edge of one end is provided with extension block 3, and this extension block 3 is a valve port.

In the utility model embodiment, described extension block 3 is located at 12 places, corner, bag 1 top, and extends 3 for rectangle, certainly, extension block 3 also can be triangle or trapezoidal, this also is feasible, and just extension block 3 rectangular meetings are more convenient folding, and adds and do not need man-hour into unnecessary excessively modification can reach this shape, so the utility model adopts the former, save production time after being provided with like this, reduced operation, reduced the productive costs of the manufacturer that knows clearly.

In the utility model embodiment, one end face of bag 1 is provided with strengthening membrane 4, here need to prove, bag 1 has two end faces, it all is feasible that strengthening membrane 4 is set on any one end face, and the strengthening membrane 4 here is a plastic film stock, and strengthening membrane 4 is provided with a plurality of breather holes 41, being provided with like this is in order to make bag 1 can keep ventilative, prevents to be provided with on the end face of bag 1 can not breathe freely behind the strengthening membrane 4 and cause the pressure in the bag 1 excessive.

Claims

1, a kind of cement package bags, include bag, described bag be provided with valve port, this valve port is folding to the bag inner chamber, the valve port opening is communicated with the bag inner chamber, and the both ends open of bag is provided with the sealing line, and it is characterized in that: described bag is rectangular, the edge of one end is provided with extension block, and this extension block is a valve port.
