[0035] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0036] In the description of this application, the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and do not require that this application must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application. The terms "connected", "connected", and "set" used in this application should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0037] Please refer to Figures 1-4. The present application provides a liquid storage bag, comprising: a liquid storage bag body 1, a sealing zipper 2, and a first gripping portion 3. A cavity 101 for holding liquid (such as breast milk, milk, water, and other liquids) is formed inside the liquid storage bag body 1. The sealing zipper 2 is provided at the opening (i.e., the milk inlet) of the cavity 101 of the liquid storage bag body 1 and is used to open and close the cavity 101. Pulling the sealing zipper 2 can connect the cavity 101 of the liquid storage bag body 1 to the outside world, and closing the sealing zipper 2 can isolate the cavity 101 from the outside world.

[0038] It should be noted that the sealing zipper 2 can also control the opening and closing degree of the cavity 101, that is, when the sealing zipper 2 is fully opened, the opening of the cavity 101 can be opened to the maximum extent, and when the sealing zipper 2 is completely closed, the opening of the cavity 101 is closed.

[0039] The first gripping portion 3 is formed by an inward depression on one side edge of the liquid storage bag body 1 in the width direction. In this way, the first gripping portion 3 serves as a gripping point for the liquid storage bag body 1, making it easier for the user to grip the liquid storage bag body 1 and providing support to prevent the liquid storage bag body 1 from sliding down. When the sealing zipper 2 is in the open state, the user can better apply force to both ends of the sealing zipper by gripping the liquid storage bag body 1 at the first gripping portion 3, so that the opening of the liquid storage bag body 1 remains open, making it easier for liquid to be injected into the cavity 101 of the liquid storage bag body 1, or to be poured out of the cavity 101 of the liquid storage bag body 1. The first gripping portion 3 is located between the sealing zipper 2 and the bottom of the liquid storage bag body 1.

[0040] As another embodiment, the number of gripping portions is two, that is, on the basis of the first gripping portion 3 being recessed inwardly on one side edge of the liquid storage bag body 1 in the width direction, the second gripping portion 8 is recessed inwardly on the other side edge of the liquid storage bag body 1 in the width direction. In this way, the second gripping portion 8 serves as another gripping point for the liquid storage bag body 1, making it convenient to grip from both sides, with more uniform force, allowing the user to apply greater gripping force, and providing stable support to prevent the liquid storage bag body 1 from sliding down. During use, the user grips the liquid storage bag body 1 through the first gripping portion 3 and the second gripping portion 8, and other operating steps are not repeated here.

[0041] In the height direction of the liquid storage bag body 1, the distance between the first gripping portion 3 and the center line of the sealing zipper 2 ranges from 18mm to 48mm, and / or the distance between the second gripping portion 8 and the center line of the sealing zipper 2 ranges from 18mm to 48mm, and the center line of the sealing zipper 2 is parallel to the cross section in the width direction of the liquid storage bag body 1. Optionally, the distance between the first gripping portion 3 and the center line of the sealing zipper 2 can be 18mm, 29mm, 30mm, 48mm, or any value between 18mm and 48mm; optionally, the distance between the second gripping portion 3 and the center line of the sealing zipper 2 can be 18mm, 29mm, 30mm, 48mm, or any value between 18mm and 48mm; the distance between the first gripping portion 3 and the center line of the sealing zipper 2, and the distance between the second gripping portion 3 and the center line of the sealing zipper 2 can be the same or different, and are not limited here.

[0042] The above distance limitation allows the first grip portion 3 and / or the second grip portion 8 to be positioned close to the opening of the cavity 101 , which is more conducive to keeping the opening open when the user grips the first grip portion 3 and / or the second grip portion 8 .

[0043] It should be noted that Figure 4 is only an example. In Figure 4, L3 is the center line of the sealing zipper 2, which is parallel to the cross-section of the liquid storage bag body 1 in the width direction; L4 is the center line of the opening of the first grip part 3 and / or the second grip part 8, which is parallel to the cross-section of the liquid storage bag body 1; H1 is the distance between the lowest point of the first grip part 3 and / or the second grip part 8 and L3; H2 is the distance between the highest point of the first grip part 3 and / or the second grip part 8 and L3; H3 is the distance between L4 and L3; H4 is the width of the sealing zipper 2 in the height direction of the liquid storage bag body 1, L5 is used to represent the line where the highest point of the first grip part 3 and / or the second grip part 8 in the height direction of the liquid storage bag body 1 (that is, the above-mentioned highest point) is located; L6 is used to represent the line where the lowest point of the first grip part 3 and / or the second grip part 8 in the height direction of the liquid storage bag body 1 (that is, the above-mentioned lowest point) is located. L3, L4, L5 and L6 are all parallel to the cross section of the liquid storage bag body in the width direction, and L3, L4, L5 and L6 are not structural lines on the liquid storage bag body 1, but lines used to indicate size (distance).

[0044] In one embodiment, the width of the liquid storage bag body 1 where the sealing zipper 2 is located is greater than the horizontal width between the first grip portion 3 and the second grip portion 8. Specifically, the liquid storage bag body 1 where the sealing zipper 2 is located is the portion of the liquid storage bag body 1 that contains the sealing zipper 2. The horizontal width between the first grip portion 3 and the second grip portion 8 can be understood as the horizontal width between the edge of the first grip portion 3 and the edge of the second grip portion 8. This embodiment facilitates opening the opening of the cavity 101 and prevents the liquid storage bag from slipping out of the hand.

[0045] Optionally, the first grip portion 3 and the second grip portion 8 are at the same height, making it easier to grip from both sides and applying force more evenly. It should be noted that the first grip portion 3 and the second grip portion 8 being at the same height means that they are opposite each other, that is, they have at least a portion of the same height. In the portion of the same height, the distance between the first grip portion 3 and the second grip portion 8 and the bottom of the liquid storage bag body 1 is equal.

[0046] Furthermore, an outwardly extending protrusion 102 is provided on an edge of one side in the width direction of the liquid storage bag body 1 (which can be the right edge or the left edge of the liquid storage bag body as shown in FIG1 ), and the protrusion 102 is communicated with the cavity 101. The first gripping portion 3 or the second gripping portion 8 on the same side as the protrusion 102 is located between the sealing zipper 2 and the protrusion 102, that is, if the protrusion 102 is located on the right edge of the liquid storage bag body 1, the first gripping portion 3 is located between the sealing zipper 2 and the protrusion 102; if the protrusion 102 is located on the left edge of the liquid storage bag body 1, the second gripping portion 8 is located between the sealing zipper 2 and the protrusion 102. Preferably, both the first gripping portion 3 and the second gripping portion 8 are located between the sealing zipper 2 and the protrusion 102, that is, regardless of which side edge the protrusion 102 is located on, the first gripping portion 3 and the second gripping portion 8 are located between the sealing zipper 2 and the protrusion 102. When in use, the protrusion 102 is torn or cut open to create an opening at the end away from the liquid storage bag body 1, and the liquid stored in the liquid storage bag, such as breast milk, can be poured out through this opening. More specifically, the protrusion 102 can be understood as a spout for pouring liquid from the liquid storage bag.

[0047] In order to reduce sudden changes in shape, in the height direction of the liquid storage bag body 1 , both ends of the protrusion 102 in the width direction are smoothly connected to the liquid storage bag body 1 .

[0048] With the horizontal line as a reference, the protrusion 102 is tilted toward the opening direction of the cavity 101 to facilitate pouring out breast milk. The inclination angle α of the protrusion 102 toward the opening direction of the cavity 101 (angle α is composed of the horizontal line L1 and the center line L2 of the protrusion 102) ranges from 0 to 35°, and can be selected as 0.01°, 5°, 10°, 15°, 16.50°, 20°, 25°, 30°, 35°, preferably 16.50°. It should be noted that in Figure 3, the cross section of the liquid storage bag body 1 is parallel to the horizontal line L1, and L1 and L2 are not structural lines on the liquid storage bag body 1, but are lines used to illustrate dimensions (angles). Preferably, the first gripping portion 3 or the second gripping portion 8 on the same side as the protrusion 102 is tilted toward the opening direction of the cavity 101, that is, if the protrusion 102 is located on the right edge of the liquid storage bag body 1, the first gripping portion 3 is tilted toward the opening direction of the cavity 101; if the protrusion 102 is located on the left edge of the liquid storage bag body 1, the second gripping portion 8 is tilted toward the opening direction of the cavity 101, which can reduce the area occupied by the protrusion 102 and the gripping portion on the same side in the height direction.

[0049] 1 and 2 , in the direction from the opening of the cavity 101 to the bottom of the liquid storage bag body 1, the first grip portion 3 and the second grip portion 8 first contract and then expand, that is, both side edges of the liquid storage bag body 1 in the width direction are recessed inward to form grooves for easier gripping. It should be noted that the structures of the liquid storage bags in Figures 1 and 2 are basically the same, the difference being the shape of the grip portions, with the opening of the grip portion in Figure 1 being larger.

[0050] In order to reduce sudden changes in shape, in the height direction of the liquid storage bag body 1 , both ends of the first gripping portion 3 and the second gripping portion 8 are smoothly connected to the liquid storage bag body 1 .

[0051] The liquid storage bag of the present application also includes: a first tear line 4 and / or a second tear line 5. The first tear line 4 is provided on the liquid storage bag body 1, and the first tear line 4 passes through the liquid storage bag body 1 along the width direction of the liquid storage bag body 1. At the same time, the first tear line 4 is located between the top of the liquid storage bag body 1 and the sealing zipper 2. The second tear line 5 is provided on the protrusion 102, and the second tear line 5 passes through the protrusion 102 along the width direction of the protrusion 102. The first tear line 4 and the second tear line 5 can be used simultaneously or separately, and there are three situations: In the first situation, the first tear line 4 is provided only on the liquid storage bag body 1. Before use, the first tear line 4 is used to prevent bacteria from entering the cavity 101. When storing breast milk, the first tear line 4 is torn open, and then the sealing zipper 2 is opened. The breast milk is injected into the cavity 101 through the opening of the cavity 101, and finally the sealing zipper is closed to achieve the purpose of sealing the breast milk. In the second situation, the second tear line 5 is provided only on the protrusion 102. When storing breast milk, unzip the sealing zipper 2 and inject breast milk through the opening of the cavity 101. When using breast milk, tear the second tear line 5 to expose the milk outlet (i.e., the end of the protrusion 102 away from the liquid storage bag body 1), and the breast milk can be poured out. The third situation: a first tear line 4 is set on the liquid storage bag body 1, and a second tear line 5 is set on the protrusion 102. When storing breast milk, tear the first tear line 4, then unzip the sealing zipper 2, inject breast milk through the opening of the cavity 101, and finally close the sealing zipper. When using breast milk, tear the second tear line 5 to expose the milk outlet, and the breast milk can be poured out. Preferably, a first notch 401 is provided at both ends of the first tear line 4, and the first notch 401 serves as a guide to prevent the liquid storage bag body 1 from being torn off when using the first tear line 4. Second notches 501 are provided at both ends of the second tear line 5 , and the second notches 501 serve as guides to prevent the liquid storage bag body 1 from being torn off-center when the second tear line 5 is used.

[0052] In this embodiment, the liquid storage bag is designed as a two-layer film, that is, the liquid storage bag body 1 includes: an inner storage layer and an outer covering layer. The inner storage layer forms a cavity 101 for holding liquid. The outer covering layer covers the inner storage layer for protection.

[0053] In this embodiment, the liquid storage bag body 1 is made of a plastic material. Specifically, the inner storage layer is made of PE (polyethylene plastic) and the outer covering layer is made of PET (polyethylene terephthalate plastic), or both the inner storage layer and the outer covering layer are made of PP (polypropylene plastic). Furthermore, the outer covering layer is made of a light-shielding material, such as a semi-transparent material or aluminum foil, to prevent the loss of nutrients in breast milk due to light exposure.

[0054] The outer wall of the outer covering is provided with graduated lines 7, arranged along the height direction, to facilitate reading the amount of breast milk used and remaining. The bottom of the liquid storage bag body 1 is provided with a horizontal base 6. When breast milk is poured into the liquid storage bag, the base 6 can stabilize the liquid storage bag body 1 on a horizontal surface due to the effect of gravity, providing support to prevent the bag body from sliding down.

[0055] Furthermore, the sealing zipper 2 is arranged on the inner wall of the outer covering layer.

[0056] It is understood from common technical knowledge that the present application may be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are merely illustrative in all respects and are not intended to be exclusive. All modifications that come within the scope of this application or are equivalent to the scope of this application are intended to be included in this application.
