[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] like Figures 1-6 As shown, this utility model addresses the problem of excessively high liquid transportation costs due to the inability to replace the inner bag in current liquid transport bags. The present invention provides the following technical solution: a liquid transport bag with a replaceable inner bag, comprising an outer bag 1 and an inner bag 2 disposed inside the outer bag 1. Openings 8 are provided at corresponding positions on both the outer bag 1 and the inner bag 2. An outer bag flange 3 is installed on the outer side of the outer bag 1 at a position matching the opening 8. An inner bag flange 5 is installed on the inner side of the inner bag 2 at a position matching the opening 8. A valve flange 4 is provided on the outer bag flange 3 at a position matching the opening 8. The valve port flange 4 is provided with multiple valve port connecting screws 6 that pass through the inner bag 2 and are fixedly connected to the inner bag flange 5. The outer bag flange 3 is provided with a tear section 31 around the valve port flange 4. After the tear section 31 is broken by external force, the outer bag flange 3 portion within the area surrounding the tear section 31 separates from the outer bag flange 3 portion outside the tear section 31. By providing the tear section 31, the outer bag flange 3 can be separated, making it convenient to remove the valve port flange 4, the inner bag flange 5 and the inner bag 2 together from the outer bag 1. The outer bag 1 can be reused, thereby reducing the usage cost of the transport liquid bag.

[0026] Specifically, the shape of the opening 8 on the outer bag 1 matches the shape of the outer bag flange 3, while the shape of the opening 8 on the inner bag 2 matches the shape of the valve flange 4. Generally, the area of ​​the opening 8 on the outer bag 1 is larger than that of the opening 8 on the inner bag 2. The edge of the opening 8 on the inner bag 2 is tightly fitted to the outer bag flange 3. In this way, the edge of the opening 8 on the inner bag 2 is pressed together by the outer bag flange 3 and the inner bag flange 5, achieving a leak-proof seal. The function of the outer bag 1 is only to protect the outer bag 1, so there is no need for a sealed connection between the outer bag 1 and the outer bag flange 3. A detachable connection can also be used to facilitate the removal of the already separated outer bag flange 3 from the outer bag 1. The inner bag flange 5 is heat-fused to the inside of the inner bag 2.

[0027] In this embodiment, as Figures 1-5As shown, the outer bag flange 3 is connected and fixed with the outer bag 1 through a plurality of fixing screws 7 arranged along the edge of the outer bag flange 3, and after the outer bag flange 3 is separated from the outer bag 1, the outer bag 1 can be repeatedly used.

[0028] In use, the outer bag flange 3 is made of plastic as a whole, and the tearing part 31 is a part of the outer bag flange 3, which separates the outer bag flange 3 into two parts. The tearing part 31 can be damaged under the action of external force when the inner bag 2 needs to be replaced. This external force can be in many ways, such as cutting the tearing part 31 with a knife, or breaking the tearing part 31 by pulling force.

[0029] As shown in the following Example 1:

[0030] As shown in the following Example 1: Figures 2-3 As shown, the tearing part 31 is a thin wall 32 formed by the upper and lower end face grooves of the outer bag flange 3. When a pulling force is applied to the valve flange 4, the thin wall 32 is torn. The operation is simple, fast and direct. The thickness of the thin wall 32 can be adjusted according to the size of the pulling force. If the pulling force is not easy to tear the thin wall 32, a knife can be used to cut the thin wall 32.

[0031] As shown in the following Example 2:

[0032] As shown in the following Example 2: Figures 4-5 As shown, the tearing part 31 is a tearing strip 34 integrally formed with the outer bag flange 3. One end of the tearing strip 34 is connected with a pull ring 33. When the pull ring 33 is pulled, the tearing strip 34 and the outer bag flange 3 are torn off. After the pull ring 33 is pulled around once, the area inside and outside the tearing part 31 is split. No large force is needed. The connection between the two side edges of the tearing strip 34 and the outer bag flange 3 is very thin, so when the pull ring 33 is pulled, it is easy to be pulled up. The operation is relatively convenient.

[0033] As shown in the following Example 3:

[0034] As shown in the following Example 3: Figure 6 As shown, the tearing part 31 is formed by a V-shaped groove 35 arranged on the upper side of the outer bag flange 3. The V-shaped groove 35 is easy to process and the depth is easy to control. It is convenient to tear the bottom of the V-shaped groove 35 with force. Moreover, the V-shaped groove 35 has a guiding effect for knife cutting, which improves the convenience of operation.

[0035] In order to facilitate the outer bag flange 3 to be in an oval or long strip shape, the shape of the opening 8 matches the outer bag flange 3, which facilitates the inner bag 2 to be put into the outer bag 1 through the opening 8 of the outer bag 1.

[0036] After the inner bag 2 and valve flange 4 are pulled out of the outer bag 1 together, the remaining outer bag flange 3 is separated from the outer bag 1, exposing the opening 8 on the outer bag 1. Then, the new inner bag 2 with inner bag flange 5 is placed into the outer bag 1 through the opening 8 on the outer bag 1, unfolded and flattened, and then the new outer bag flange 3 is installed. Finally, the original valve flange 4 is installed, which can fix the inner bag 2 and the outer bag 1 together, realizing the reuse of the outer bag 1 and solving the problem that the inner bag of the current transport liquid bag cannot be replaced, resulting in excessive liquid transportation costs.

[0037] The existing inner bag flange 5 has a disc-shaped structure. When in use, the liquid bag is set vertically. Both the valve flange 4 and the inner bag flange 5 are set vertically. When the liquid is drawn from the valve flange 4, external air can easily enter the upper space of the inner bag 2, which will affect the efficiency of negative pressure liquid drawing and will also cause the liquid in the inner bag 2 to not be completely drawn out.

[0038] Therefore, in this embodiment, as Figures 7-9 As shown, the inner bag flange 5 includes a flange housing 52 and a liquid inlet 54 located at the lower end of the flange housing 52. The flange housing 52 extends vertically downward, and a liquid extraction through hole 51 corresponding to the valve port flange 4 is provided on the upper side of the flange housing 52. By setting the inner bag flange 5 in a downward extending shape, the upper part of the inner bag flange 5 is sealed, so external air is not easily allowed to enter the inner bag 2 during liquid extraction. At the same time, several small liquid inlet holes 53 are provided on the lower side wall of the flange housing 52, which can increase the speed at which liquid in the inner bag 2 enters the inner bag flange 5.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0041] In the utility model, unless another definite provision and limitation, the term "connect", "fix" and so on should do the broad sense understanding, for example, "fix" can be fixed connection, also can be detachable connection, or be integrated;Can be mechanical connection, also can be electric connection;Can be directly connected, also can be indirectly connected through the intermediate medium, can be two element inside's intercommunication or two element's mutual action relation, unless another definite limitation.For the ordinary skill in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to the specific circumstances.

[0042] In addition, the technical solutions of various embodiments of the present application can be combined with each other, but must be based on the realization of ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, also not within the protection scope required by the present application.
