Abstract
Description
Technical Field
[0001] The utility model relates to the field of valve bags, in particular to a square bottom valve bag used for cement packaging. Background Art
[0002] Valve bags, commonly known as paste-bottom bags, are internationally popular packaging bags. They are fed from the top or bottom valve port and use special filling equipment. After filling the materials, they are packed into cubes. The bags are neatly stacked and beautiful, and are environmentally friendly bags.
[0003] At present, cement is often packaged in valve bags. However, once the existing valve bags are opened, they cannot be resealed. Cement is easily exposed to the air for a long time and tends to agglomerate, which affects its reuse.
[0004] Therefore, there is an urgent need for a square bottom valve bag for cement packaging that can solve the above problems. Utility Model Content
[0005] The utility model aims to provide a square bottom valve bag for cement packaging to solve the problems existing in the above-mentioned prior art.
[0006] To achieve the above purpose, the utility model provides the following solutions:
[0007] The utility model provides a square bottom valve bag for cement packaging, comprising a bag body, a top side of the bag body is provided with a valve port, and a side portion of the valve port is provided with a secondary sealing component.
[0008] Preferably, the bottom and the top of the bag body are both square structures.
[0009] Preferably, a lining layer is provided on the inner side of the bag body.
[0010] Preferably, a first drawstring is provided on the upper outer portion of the bag body, and a second drawstring is provided below the first drawstring.
[0011] Preferably, the secondary sealing assembly comprises a pressure strip, both ends of which are connected to the pressure block via elastic bands.
[0012] Preferably, a sealing groove is provided on the inner side of the pressure strip, and the sealing groove cooperates with the pressure block.
[0013] Compared with the prior art, the utility model has achieved the following beneficial technical effects:
[0014] The utility model provides a square bottom valve bag for cement packaging, comprising a bag body, a valve port being arranged on one side of the top of the bag body, and a secondary sealing component being arranged on the side of the valve port; by arranging the secondary sealing component, when the valve bag is opened, the valve port can be sealed for the second time, so that the unused cement in the bag body can be sealed and stored, avoiding agglomeration that affects reuse. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0017] Figure 2 The utility model provides a schematic structural diagram of a secondary sealing component of a square bottom valve bag for cement packaging. DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The utility model aims to provide a square bottom valve bag for cement packaging to solve the problems existing in the prior art.
[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0021] Embodiment 1:
[0022] This embodiment provides a square bottom valve bag for cement packaging, such as Figure 1 and 2 As shown, it comprises a bag body 1 , a valve port 2 is arranged on one side of the top of the bag body 1 , and a secondary sealing component 3 is arranged on the side of the valve port 2 .
[0023] Specifically, the bottom and the top of the bag body 1 are both square structures, so that after being filled with cement, it can be packed into a cube, and the packages are neatly stacked and beautiful.
[0024] Furthermore, an inner lining layer is provided on the inner side of the bag body 1, which mainly plays an isolating role to prevent the cement from directly contacting the bag body, and can also play an effect of reducing friction to facilitate the pouring of cement.
[0025] Furthermore, a first drawstring 4 is provided on the upper outer portion of the bag body 1 , and a second drawstring 5 is provided below the first drawstring 4 . The first drawstring 4 and the second drawstring 5 are mainly for facilitating carrying and dumping.
[0026] Furthermore, the secondary sealing assembly 3 includes a pressure strip 31 , and both ends of the pressure strip 31 are connected to a pressure block 33 via an elastic band 32 .
[0027] Furthermore, a sealing groove 34 is provided on the inner side of the pressure strip 31 , and the sealing groove 34 cooperates with the pressure block 33 .
[0028] The utility model provides a square bottom valve bag for cement packaging. When secondary sealing is required, the pressing block 33 is passed around the valve port 2 so that it is located at the sealing groove 34. Due to the elastic effect of the elastic band 32, the pressing block 33 will press the valve port 2 tightly, thereby achieving sealing and avoiding agglomeration that affects reuse.
[0029] The utility model uses specific examples to illustrate the principle and implementation of the utility model. The above examples are only used to help understand the method and core idea of the utility model. At the same time, for those skilled in the art, according to the idea of the utility model, there will be changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as limiting the utility model.
