[0010] Hereinafter, one embodiment of a breast milk storage bag according to the present invention will be described with reference to Figs. 1 to 7.

[0011] FIG. 1 is a plan view showing an embodiment of a breast milk storage bag. In the following description, the directions indicated by the arrows in the breast milk storage bag 1 in the state shown in FIG. 1 are defined as the up-down direction and the left-right direction (width direction).

[0012] The breast milk storage bag 1 of this embodiment is formed by placing two rectangularly cut film sheets 1A and 1B facing each other and welding their peripheral edges 1a, 1b, 1c, and 1d together (the welded portions are indicated by dots). The welding of the peripheral edges creates an internal space. An openable and closable zipper 3 is interposed between the opposing film sheets A and 1B to divide the internal space into two spaces S1 and S2.

[0013] As is generally known, the film sheets 1A and 1B have a laminated structure with a sealant layer made of polyethylene, polypropylene, or the like on the inside and a protective layer made of PET, nylon, or the like with barrier properties on the outside.

[0014] The zipper part 3 is generally known and is formed by welding a strip-shaped member 3A, which has a protrusion extending in the width direction and a recess facing the protrusion into which the protrusion fits, between two film sheets 1A, 1B. In this case, the rectangular internal space S1 partitioned by the zipper part 3 forms the breast milk receiving part 5, and the rectangular internal space S2 forms the breast milk storage part 10. In other words, the upper part of the breast milk storage bag functions as a receiving part (breast milk cup) when expressing milk by hand, and the lower part functions as a storage part (breast milk storage part) to collect and store expressed breast milk.

[0015] The breast milk storage part 10 has a function of transferring the breast milk stored inside to a baby bottle after boiling it in hot water, and the zipper part 3 is left open when expressing milk and closed during storage to prevent leakage.

[0016] The breast milk receiving portion 5 has a curved cut line 5a that can be cut to curve along the surface of the breast when placed against the breast during milking, and a tear-off portion formed on the opposing film sheets 1A, 1B so that the breast milk receiving portion 5 can be cut off along the zipper portion 3. The tear-off portion in this embodiment is constituted by a notch 1D formed on both side edges 1c, 1d of the film sheets 1A, 1B, and the breast milk receiving portion 5 is separated from the breast milk storage portion 10 from this notch 1D.

[0017] The curved cut line 5a in this embodiment is formed so as to curve upward from one end of the chuck portion 3, extend widthwise near the upper end, and reach the side edge 1d. This curved cut line 5a can be formed, for example, by subjecting the surface of the film sheets 1A, 1B to laser processing or perforation processing, and is preferably formed with multiple lines (three in this embodiment), which maintains the directionality during cutting and enables stable cutting.

[0018] The curved cut line 5a may have any curved shape as long as it does not leave a gap between the surface of the breast when the curved cut line is cut and placed against the breast during milking, and the manner in which it is curved can be modified as appropriate. The curved cut line in this embodiment is formed in a shape that allows the breast milk receiving portion 5 to cover the upper side of the breast. For this reason, the curved cut line 5a shown in Figure 1 is only an example, and it can be modified as appropriate, for example, as shown in Figure 8, such as curving upward from one end of the zipper portion 3, passing through a curved portion 5b where the angle of the upward rise becomes gradually gentler near the upper end, and extending in the width direction to the side edge 1d.

[0019] The notch 1D formed in the breast milk receiving part 5 is the part that is cut from this position after the zipper part 3 is sealed in order to express milk into the breast milk receiving part 5 and store the breast milk in the breast milk storage part 10, thereby separating the breast milk receiving part 5 from the breast milk storage part 10. In addition to the notch 1D, a cut line extending in the width direction may be formed by the above-mentioned laser processing, perforation processing, or the like.

[0020] The breast milk storage section 10 has a pouring cut line 10a along which the zipper section 3 can be cut off when pouring out the expressed (stored) breast milk. This pouring cut line 10a is the part that is cut when pouring out the breast milk stored in the breast milk storage section 10, and is formed to extend parallel to the zipper section 3 so that the zipper section 3 can be cut off.By cutting this part, an opening 10E is formed that serves as the pouring section for the stored breast milk.

[0021] Like the curved cut line 5a, the pouring cut line 10a can be formed by laser processing, perforation, or the like. The pouring cut line 10a may have a structure in which it is cut by a notch. That is, notches similar to the notches 1D may be formed on both sides of the pouring cut line 10a.

[0022] In this embodiment, the breast milk storage compartment 10 has guide welds 12 welded to form inclined sections 12a that gradually rise inward. These guide welds 12 are formed on both side edges 1c, 1d, and are formed between the opposing film sheets 1A, 1B, straddling the pouring cut line 10a. These inclined sections 12a function to guide the outflowing breast milk so that it can be poured steadily without spilling over the surrounding area when the breast milk stored in the breast milk storage compartment 10 is poured.

[0023] In this embodiment, a gauge 15 is attached to the surface of the breast milk storage unit 10, allowing the amount of expressed breast milk to be monitored. By attaching this gauge 15, it becomes possible to monitor the amount of expressed breast milk. Furthermore, in this embodiment, a bottom 17 is welded to the bottom edge 1b of the breast milk storage unit 10, making the entire bag a self-standing bag. By forming this bottom 17, the breast milk storage unit 10 can be stored in a refrigerator or freezer in a stand-up style, improving ease of handling.

[0024] Next, the manner of use and the effects of the breast milk expression and storage bag 1 will be described with reference to Figs. Initially, when expressing milk, the upper end of the breast milk expression and storage bag 1 is cut along the curved cut line 5a (Fig. 1, Fig. 2). Before being cut along the curved cut line 5a, the four corners of the breast milk receiving part 5 and breast milk storage part 10 are sealed, and electron beams or gamma rays can be used to sterilize the breast milk expression and storage bag.

[0025] In this state, the zipper part 3 is opened, the breast milk storage part 10 is grasped, and milk is expressed (by hand) in the breast milk receiving part 5. In this case, the opening 5E formed by the curved cut line 5a is curved along the surface of the breast (upper side of the breast), so it comes into close contact with the breast when expressing milk, allowing the milk to be poured into the breast milk receiving part 5 without any problems (Fig. 3).

[0026] Since the zipper part 3 is open, breast milk expressed in the breast milk receiving part 5 is stored directly in the breast milk storage part 10. At this time, the amount of breast milk expressed can be monitored using the gauge 15. After the breast milk has been stored in the breast milk storage part 10, the zipper part 3 is closed to seal the breast milk storage part 10, and the breast milk receiving part 5 is detached via the notch 1D (Fig. 4). The stored breast milk is sealed by the zipper part 3, preventing leakage. Furthermore, the breast milk storage part 10 can stand on its own using the bottom part 17, so it can be stored upright in a refrigerator or freezer.

[0027] In this case, with the breast milk receiving portion 5 separated from the notch 1D, the zipper portion 3 is folded (for example, folded twice) and a milking label 20 is attached, allowing the date of milking and other information to be written on it (Figure 5).

[0028] The breast milk storage part 10 containing the breast milk is then warmed in a hot water bath and transferred to the baby bottle 100 (Fig. 7). At this time, by cutting along the pouring cut line 10a and grasping the breast milk storage part 10 by pinching it from both sides, the opening 10E expands into an oval shape, making it easier to pour the breast milk into the mouth 100a of the baby bottle 100. During pouring, the sloping part 12a of the guide weld part 12 guides the outflowing breast milk, allowing it to be poured smoothly into the baby bottle 100 without spilling.

[0029] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be modified in various ways. In the above-described configuration, the shape and size of the film sheets 1A and 1B, the position of the zipper part 3, the configuration of the tear-off part, the shape of the curved cut line 5a, etc. can be modified as appropriate. Also, the guide welding part 12 may not be provided inside the breast milk storage part 10. [Explanation of symbols]
