Fig. 3 is a cross-sectional view at A-A in fig. 1, and shows a cold compress bag according to a different embodiment, and in fig. 3 and 4, only a part of the cross-sectional view is shown for convenience of illustration. Fig. 5 is a top view of yet another embodiment of a cold pack.

Referring to fig. 1 to 5, and mainly to fig. 1 and 2, the cold pack according to the present embodiment includes: a main body 101, and a liquid storage unit 102 is formed in the main body 101. The liquid storage unit 102 includes a plurality of liquid storage cavities 103, and the plurality of liquid storage cavities 103 are arranged in a rectangular array. A spacer 104 is provided between the liquid storage chambers 103 adjacent to each other. The liquid for cold compress of the user is stored in the liquid storage chamber 103, and the liquid for cold compress of the user is not stored in the spacer 104 so that the body 101 can be bent at the position of the spacer 104 in the case where the liquid stored in the liquid storage chamber 103 is lumpy.

The cold compress bag of this embodiment can laminate the position that needs cold compress of user in a larger area, improves the effect of cold compress. Specifically, since the main body 101 of the cold pack is provided with the liquid for cold compress of the user, even in a state where the liquid of the cold pack is frozen, the main body 101 does not freeze over a large area at least at the position of the spacer 104, and therefore, the main body 101 can be bent at the position of the spacer 104. Therefore, the cold compress bag can be adjusted to a certain extent according to the structure of the part of the user needing cold compress, so that the part of the user needing cold compress can be attached to a larger area, and the cold compress effect is improved.

In the present embodiment, the spacer 104 does not store the liquid for cold compress of the user, and it should be understood that the main function of the spacer 104 is not to store the liquid, and on the premise that a pipe (for example, a communication pipe 105 described later) must be provided for the liquid to be fed or discharged, but these pipes only serve as a function of communicating with each liquid storage chamber 103, and the liquid remaining in the pipe is very small, and cannot be used as the liquid for cold compress of the user directly.

The main body 101 of the cold pack may be formed by sealing, for example, a flexible sheet 106. The material of the sheet 106 is not particularly limited, and a known plastic material such as polyethylene can be used. The body 101 may include a pair of sheets 106 opposing each other. The shape of the flat surface of the sheet 106 is not particularly limited, and may be, for example, a substantially square shape, a rectangular shape, or an oblong shape. At least one of the pair of sheets 106 is provided with a plurality of raised portions 107 arranged in a rectangular array. The adjacent bulge portions 107 are connected by a connection portion 108 having a planar shape. The sheet 106 is sealed at its outer periphery and at the location of the connection 108. In a state where the sheets 106 are sealed, the pair of sheets 106 form the liquid storage chamber 103 in a region where the bulge portion 107 is formed, and the spacer 104 in a region where the connection portion 108 is formed. Thereby, the liquid storage chamber 103 can be easily formed. Further, since the thickness of the spacer 104 is much smaller than the thickness of the position of the liquid storage chamber 103, but is substantially the same as the thickness when the two sheets 106 are stacked, and the region is hardly present with liquid, bending can be easily performed even after the liquid freezes.

Referring to fig. 3, in the pair of sheets 106, a plurality of raised portions 107 may be formed in one sheet 106, and the other sheet 106 may be planar. Referring to fig. 4, a plurality of raised portions 107 may be formed in each of the pair of sheets 106, and the raised portions 107 may be formed at positions opposite to each other in the sealed state. The sealing method is not particularly limited, and various known sealing methods such as hot melt adhesive bonding and ultrasonic welding can be used.

The liquid stored in the liquid storage cavity 103 can be a phase change material for cold application or water. In the case of using a phase change material, for example, the liquid may be stored in the liquid storage chamber 103 in advance and then sealed, and in the case of using water as the liquid for cold application, the liquid may be stored in the liquid storage chamber 103 in advance and may be added at the time of use (described later).

With continued reference to fig. 1 and 5, the manner of the rectangular array of the liquid storage chambers 103 of the liquid storage unit 102 in the main body 101 is not particularly limited, and for example, the main body 101 may be substantially rectangular, the main body 101 may have a long side direction and a short side direction, and the main body 101 may be bent mainly in the long side direction.

Referring to fig. 5, the liquid storage chambers 103 may be arrayed only in the long side direction of the main body 101, in which case the liquid storage chambers 103 may be elongated extending in the short side direction of the main body 101, i.e., the length of the liquid storage chambers 103 in the short side direction of the main body 101 is greater than the length of the liquid storage chambers 103 in the long side direction of the main body 101. The length of the liquid storage chamber 103 in the longitudinal direction extends substantially to the edge of the main body 101 in the short side direction. By making the length of the liquid storage chamber 103 in the short side direction of the main body 101 longer than the length of the liquid storage chamber 103 in the long side direction of the main body 101, the cold pack can easily bend the main body 101 in the long side direction of the main body 101.

Referring to fig. 1, the liquid storage chambers 103 may be arrayed in the longitudinal direction and the short direction of the main body 101, respectively, and in this case, the liquid storage chambers 103 may be arranged in a lattice shape (mahjong mat shape) as a whole, and in this embodiment, the shape of the liquid storage chamber 103 may be, for example, a substantially square shape, a rectangular shape, an elliptical shape, a rectangular shape, or the like. In the case where the liquid storage chamber 103 has a rectangular, elliptical, or oblong shape, the liquid storage chamber 103 may have a longer length in the longitudinal direction of the main body 101 than in the short-side direction. The cold pack can be easily folded into the body 101 along the longitudinal direction of the main body 101.

The distance between the two liquid storage chambers 103 (the distance of the spacer 104) is determined according to the degree of bending required, and for example, when the limbs and joints (e.g., hands, feet, knee joints, ankle joints, elbow joints, etc.) of the user need to be wrapped around, the distance of the spacer 104 may be appropriately increased so that the entire body 101 can be bent into a substantially cylindrical shape. When the user needs to apply only to the forehead, the back, or the like, for example, the distance of the spacer 104 can be reduced appropriately, and the entire body 101 can be bent into a substantially curved shape so as to be able to adhere to the skin of the user.

With continued reference to fig. 1, 2, 5, in some embodiments, to reduce the cost of the cold pack, the body 101 may be provided with a fluid inlet 109, the fluid inlet 109 being in communication with the reservoir unit 102. Specifically, the entire cold pack bag can be compressed into a substantially flat shape in the initial state, and thus the weight, packaging area, and the like of the entire cold pack bag can be greatly reduced, and the cost of the cold pack bag can be greatly reduced when transportation is required. When it is necessary to use, water or the like is injected through the liquid inlet 109 of the main body 101. The liquid inlet 109 is formed, for example, at the edge of the main body 101. Specifically, since the sheet 106 forming the main body 101 is sealed in the circumferential direction to form the liquid storage unit 102 that can store liquid, an unsealed area may be reserved at one position of the edge of the sheet body, for example, in the process of sealing the edge of the outer periphery of the sheet 106 of the main body 101, whereby the liquid inlet 109 is formed at the unsealed area. The liquid inlet 109 may be sealed by a plug or a cap 110. Through setting up inlet 109, not only can use and store the cold compress bag more conveniently, can reduce the cost of cold compress bag transportation moreover. For example, when the cold pack is not needed, the water in the cold pack can be discharged through the liquid inlet 109, i.e. the cold pack can be stored, and the needed storage space is small. When the liquid storage bag is required to be used, liquid such as water is injected into the liquid storage unit 102 through the liquid inlet 109, then the liquid inlet 109 is plugged through the plug or the cover 110 and is placed in a refrigerator for freezing, and the liquid in the liquid storage unit 102 of the cold compress bag can be taken out for use after freezing.

With continued reference to fig. 1 to 5, in the case where liquid is injected into the liquid storage unit 102 of the main body 101 through the liquid inlet 109, a communication pipe 105 for communicating with the adjacent liquid storage chambers 103 may be formed in the partition 104. Specifically, a communication pipe 105 may be formed between one liquid storage chamber 103 and the partition 104 between any one of the liquid storage chambers 103 adjacent thereto. The communication duct 105 may be formed when the sheet constituting the main body 101 is sealed. For example, since the sheet 106 is sealed at the positions of the connection portions 108, when the sheet 106 is sealed at the positions of the connection portions 108, only a portion of each connection portion 108 may be sealed, while another portion of the connection portion 108 is not sealed, to form the communication pipe 105 at the unsealed position.

As described above, the adjacent bulge portions 107 are connected by the connection portion 108 having a planar shape, specifically, the connection portion 108 has a substantially rectangular shape, the length of the connection portion 108 is substantially the same as the length of the bulge portion 107, and the width of the connection portion 108 is the distance between the adjacent bulge portions 107. The intermediate position in the substantially longitudinal direction of the connection portion 108 is not sealed, and thereby a communication pipe 105 is formed at the substantially intermediate position in the longitudinal direction of the partition 104. The width of the communication pipe 105 is not particularly limited as long as the liquid can smoothly flow therethrough, and the block in the communication pipe 105 may be broken as the body 101 is bent at the position of the spacer 104 in a state where the liquid filled in the communication pipe 105 becomes a block. For example, the width of the communication pipe 105 may be 1mm or more and 3mm or less. Further, the overall thickness of the position of the communication pipe 105 and the overall thickness of the superposition of the two sheets 106 are substantially the same, but much smaller than the thickness of the region where the liquid reservoir 103 is formed. Thus, even if frozen blocks exist in the communication pipe 105, since the blocks have a very small width and a very thin thickness, the blocks can be easily broken off, and the main body 101 can be bent in the partition 104.

Further, in some embodiments, the main body 101 may be further provided with a liquid outlet 111, and the liquid outlet 111 communicates with the liquid storage unit 102. Liquid injected into the liquid storage chamber 103 of the liquid storage unit 102 via the liquid inlet 109 can be discharged from the liquid outlet 111. The liquid outlet 111 is formed, for example, at the edge of the main body 101. Specifically, since the sheet 106 forming the main body 101 is sealed in the circumferential direction to form the liquid storage unit 102 that can store liquid, in the process of sealing the edge of the outer periphery of the sheet 106 of the main body 101, for example, an unsealed area may be reserved at another position of the edge of the main body 101, whereby the liquid outlet 111 is formed at the unsealed area. The liquid outlet 111 may be closed by a plug, a cap 110, or the like. By providing the liquid outlet 111, the air in each liquid storage cavity 103 in the liquid storage unit 102 can be emptied as much as possible while liquid is fed, so that the liquid storage cavities 103 are ensured to be filled with liquid. When the liquid is formed into ice, the smoothness of the entire body 101 can be improved to some extent.

Although the example in which the communication pipe 105 is formed between one of the liquid storage chambers 103 and the partition 104 between any of the liquid storage chambers 103 adjacent thereto has been described above, the present utility model is not limited thereto, and for example, in order to further empty the air in each of the liquid storage chambers 103 in the liquid storage unit 102, a communication pipe 105 for communicating the adjacent liquid storage chamber 103 is formed in a part of the plurality of partition 104, and the communication pipe 105 is distributed such that the plurality of liquid storage chambers 103 of the liquid storage unit 102 are communicated in series from the liquid inlet 109 to the liquid outlet 111 (refer to the trajectories of the liquid inlet and the liquid outlet indicated by the center lines in fig. 1). Specifically, for example, the liquid inlet 109 communicates with one liquid storage chamber 103 also located at one edge of the main body 101. The liquid storage chambers 103 are arrayed along the long side direction and the short side direction of the main body 101, respectively. One of the liquid storage chambers 103 located at both ends in the longitudinal direction of the main body 101 communicates with the other liquid storage chamber 103 adjacent thereto in the short-side direction of the main body 101 through a communication pipe 105. Further, in addition to the liquid storage chambers 103 at both ends in the longitudinal direction of the main body 101, the other liquid storage chambers 103 are respectively communicated with the other liquid storage chamber 103 adjacent thereto in the longitudinal direction through the communication pipe 105. Thus, these communication pipes 105 are formed to extend from the liquid inlet 109 to the other end in the longitudinal direction of the main body 101, then to extend in a plurality of turns, and to be connected to the unidirectional passage of the liquid outlet 111, thereby communicating the liquid storage chambers 103 in series from the liquid inlet 109 to the liquid outlet 111. This can sequentially fill the liquid storage chambers 103, and can sufficiently empty the air in each liquid storage chamber 103.

The specific features described in the above embodiments may be combined in any manner without contradiction, and for unnecessary repetition, the present embodiment does not separately describe various possible combinations.

The above examples are only for illustrating the technical solution of the present embodiment and are not limited thereto, and any modification or equivalent substitution that does not depart from the scope of the present embodiment should be included in the technical solution of the present embodiment.
