[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model provides a technical solution: a liquid leakage-proof ice bag structure, comprising an outer covering layer 1, a surface protection strip 2, a side protection strip 3, a bag body 4, a non-woven fabric layer 401, an outer waterproof layer 402, an inner waterproof layer 403, a hot-pressed edge sealing 5, an inner refrigerant 6, an edge sealing covering layer 7, a sealant 8 and an inner rubber strip 9. The surface protection strip 2 is fixedly installed on the top and bottom surfaces of the outer covering layer 1, and the side protection strip 3 is fixedly installed on the side of the outer covering layer 1. The inner wall of the outer covering layer 1 is bonded to the outer surface of the bag body 4, a hot-pressed edge sealing 5 is provided on the edge of the bag body 4, an inner refrigerant 6 is provided in the bag body 4, and an edge sealing covering layer 7 is provided on the outside of the hot-pressed edge sealing 5. The end of the edge sealing covering layer 7 is connected and fixed to the surface edge of the bag body 4 by a sealant 8. An inner rubber strip 9 is fixed on the inner side of the edge sealing covering layer 7, and the inner rubber strip 9 is bonded to the outer edge of the hot-pressed edge sealing 5.

[0024] In this example, the surface protection strips 2 are symmetrically distributed on the top and bottom surfaces of the outer covering layer 1, and the surface protection strips 2 are distributed at equal intervals. The above structural design can prevent the outer covering layer 1 from directly contacting a large area with external objects, thereby reducing the wear rate.

[0025] The side protection strip 3 is arranged around the middle of the outer edge of the outer covering layer 1. The width of the side protection strip 3 is greater than 1 / 3 of the width of the outer edge of the outer covering layer 1. The above structural design enables the side protection strip 3 to shield and protect the edge of the outer covering layer 1.

[0026] The bag body 4 includes a non-woven fabric layer 401, an outer waterproof layer 402 and an inner waterproof layer 403. The outer waterproof layer 402 is fixedly installed on the outer surface of the non-woven fabric layer 401, and the inner waterproof layer 403 is fixedly installed on the inner surface of the non-woven fabric layer 401. The above structural design makes the bag body 4 have higher structural strength and stronger leak-proof effect.

[0027] The outer waterproof layer 402 and the inner waterproof layer 403 are symmetrically distributed about the non-woven fabric layer 401. The thickness of the non-woven fabric layer 401 is greater than the sum of the thicknesses of the outer waterproof layer 402 and the inner waterproof layer 403. The above structural design ensures that the bag body 4 is not easily damaged and has a strong waterproof effect.

[0028] The front view cross-section of the edge-sealing coating layer 7 is in a "匚" shape, and the thickness of the edge-sealing coating layer 7 is greater than the thickness of the outer coating layer 1. The above structural design can wrap and protect the hot-pressed edge 5 to avoid wear of the hot-pressed edge 5.

[0029] The sealant 8 is symmetrically distributed about the center of the hot-pressed edge 5. The inner side of the sealant 8 is in contact with the junction of the edge of the bag body 4 and the hot-pressed edge 5. The above structural design can position the edge-sealing coating layer 7 and seal the inner side of the edge-sealing coating layer 7 to improve the anti-leakage effect.

[0030] The center of the inner rubber strip 9 is on the same horizontal plane as the center of the hot-pressed edge 5, and the width of the inner rubber strip 9 is greater than half of the overall thickness of the hot-pressed edge 5. The above structural design can seal the central gap of the hot-pressed edge 5.

[0031] Working principle: The outer coating layer 1 is a heat-shrinkable film, which is integrally wrapped outside the bag body 4 and the edge-sealing coating layer 7 to avoid wear of the bag body 4 and the edge-sealing coating layer 7. Together with the surface protection strip 2 and the side protection strip 3, the overall service life of the device is extended;

[0032] The bag body 4 composed of the non-woven fabric layer 401, the outer waterproof layer 402 and the inner waterproof layer 403 has a greatly increased overall strength and also has a strong water-proof effect. Together with the edge-sealing coating layer 7, the sealant 8 and the inner rubber strip 9, the edge hot-pressed edge 5 is integrally protected and sealed, further improving the anti-leakage effect. This is the working principle of the anti-leakage ice bag structure.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
