Problems solved by technology

[0003] The disadvantage of this structure is that since the filling tube and sealing cover are arranged on the bag body, there are many manufacturing steps, which consume many resources and parts, and the filling tube and sealing cover need to occupy a large space, while the filling tube and the sealing cover need to occupy a large space. The space occupied by tubes and sealing caps is difficult to use, which leads to a lot of wasted space for flexible packaging containers with filling tubes when stored and cannot be used

Embodiment 1

[0019] Such as Figure 1-4 As shown, the flexible packaging container for liquid materials in this embodiment includes a bag body 1 and a multifunctional tube. The bag body 1 has a filling port 103. The multifunctional tube is a film sleeve 2 and a film sleeve 2. The fixed end 203 is connected to the filling port of the bag body 1. In the initial state, the film sleeve 2 is located in the bag body 1. When the liquid material is filled with the bag body 1, the film sleeve 2 is squeezed into a sheet by the liquid material and the filling port It is sealed, and the film sleeve 2 is turned inside and out and extends out of the bag body 1 when it is poured.

[0020] The film sleeve 2 is composed of a first film sheet 201 and a second film sheet 202. The top of the inner side wall of the first film sheet 201 and the top of the inner side wall of the second film sheet 202 are connected together. The bottoms of the inner side walls of the second film sheet 202 are connected together to ...

Embodiment 2

[0028] Such as Figure 5 As shown, the difference between the flexible packaging container for liquid materials in this embodiment and Embodiment 1 is:

[0029] The inner wall of the film sleeve 2 is provided with a turning auxiliary pull tab 4, the rear end of the turning auxiliary pull tab 4 is connected to the outlet 204 of the film sleeve 2, and the front end of the turning auxiliary pull tab 4 is located at the filling port 104 of the bag body 1. In other words, the front end of the auxiliary turning pull tab 4 does not exceed the filling opening 104 of the bag body 1, so as to prevent the front end of the turning auxiliary pull 4 from being unintentionally pulled and causing liquid leakage.

[0030] In this way, the film sleeve 2 can be taken out quickly and conveniently by dragging the front end of the flip auxiliary pull tab 4 during dumping, and the inside and outside of the film sleeve 2 can be flipped, which is more convenient and quick to use.

[0031] The wall thickness ...

Embodiment 3

[0034] The difference between the flexible packaging container for liquid materials in this embodiment and Embodiment 1 is:

[0035] The wall thickness of the film sleeve 2 is 0.02 mm.

Abstract

The invention provides a flexible packaging container for liquid-state materials. The flexible packaging container comprises a bag body and a multifunctional pipe. A filling opening is formed in the bag body, the multifunctional pipe is a thin film sleeve, the fixed end of the thin film sleeve is connected with the filling opening of the bag body, an outlet of the thin film sleeve in an initial state stretches into the bag body, when the bag body is filled with the liquid-state materials, the thin film sleeve is extruded into a sheet by the liquid-state materials to seal the filling opening, when the liquid-state materials are poured out, the inner portion and the outer portion of the thin film sleeve are overturned, and the thin film sleeve stretches out of the bag body. Due to the arrangement of the thin film sleeve, the bag body can be filled with the liquid-state materials and automatically seal the filling opening, in necessary, the filling opening can be rapidly opened so that the liquid-state materials can be poured out, especially in the initial state and after the liquid-state materials are stored, the whole thin film sleeve is located in the bag body, the thin film sleeve cannot occupy additional space whether the bag body is not filled with the materials or the bag body is filled with the materials, the space can be more effectively utilized, the storage cost is reduced, the flexible packaging container is very convenient to use, consumed resources can be effectively reduced, the production cost is greatly reduced, and the flexible packaging container is easy to popularize.

Description

Technical field [0001] The invention relates to a flexible packaging container, more specifically to a flexible packaging container for liquid materials. Background technique [0002] At present, the flexible packaging container used to store liquid materials is usually a flexible packaging container with a filling tube. Its structure is composed of a bag body, a filling tube and a sealing cap. The bag body has an opening and the filling tube is installed in the opening of the bag body. Above, the sealing cap is installed on the filling tube. The function of the filling tube is to fill the liquid material into the bag. When in use, the liquid material is poured out of the bag through the filling tube. The sealing cover is used to seal the filling tube to prevent outside air and dust from entering the filling tube and contaminating the filling tube and the liquid materials stored in the bag. [0003] The disadvantage of this structure is that because the bag body is equipped with a...
