2. The reusable ice bag mainly comprises four layers of two layers of outer plastic and two layers of inner non-woven fabric, wherein the two layers of inner non-woven fabric are filled with water-absorbing cold-storage agent, the two layers of plastic films are wrapped outside the two layers of inner non-woven fabric, and the four sides of the plastic films are firmly sealed; it is firm and durable, can be repeatedly used, but has complex structure, troublesome processing and high production cost.
3. The water-absorbing cold-storage agent is wrapped by a plastic film, the top layer of the product is bonded with the four sides of the middle layer, and at least one water inlet is arranged on one side of the product, so that the product cannot be used as an ice bag of a continuous unit.
As shown in fig. 1 to 10, the present application provides an ice pack including: a bag body 10 and a water-absorbing cold-storage agent 30.
As shown in fig. 1, 2, 9 and 10, the bag body 10 includes two envelopes 11, and the edges of the two envelopes 11 are hermetically connected and enclose a containing cavity 14. The envelope 11 is a plastic envelope, the material of the envelope 11 may be Polyethylene (PE), Polyethylene terephthalate (PET), etc., and the envelope 11 made of the above material is strong and not easy to tear, and can be used for many times. The edges of the two envelopes 11 are connected in a heat sealing mode, and the connection mode is reliable in connection and simple in structure. In addition, the ice bag can be in any shape and any size, and the shape and the size of the ice bag can be selected by a person skilled in the art according to specific situations.
As shown in fig. 1, 2, 9 and 10, the water-absorbing coolant 30 is provided in the housing chamber 14. The water-absorbing coolant 30 may be a high molecular water-absorbing resin. Specifically, the water-absorbing coolant 30 may be sodium polyacrylate high molecular water-absorbing resin, starch grafted high molecular water-absorbing resin, or cellulose grafted high molecular water-absorbing resin. The high molecular water-absorbing resin is not compatible with water and an organic solvent, and has good absorption performance and water retention capacity; the absorption capacity of the high molecular water-absorbing resin is high, can reach more than thousand times of the self weight, and has strong water retention property, and the water is not easy to lose even under the conditions of heating and pressurizing; has good stability to light, heat and acid and alkali, no toxicity and odor, and good biodegradability.
As shown in fig. 1, 2, 9 and 10, the plurality of through holes 20 are provided at the edge of the envelope 11 and extend in the circumferential direction of the envelope 11, and the area of the envelope 11 in which the through holes 20 are provided occupies one-half to two-thirds of the area of the envelope 11.
The application provides an ice bag, water gets into the inside of the bag body 10 through a plurality of through-holes 20, and the cold-storage agent 30 that absorbs water inflation makes the ice bag be the arc that the middle part is big, the edge is little. In the process of freezing the ice bags, the contact position of the adjacent ice bags is mainly the middle part of the ice bag, and the edges of the ice bags are not easy to contact; when the liquid seeped from the water absorption coolant 30 flows to the outside of the ice bags from the through holes 20, the edges of the ice bags are not easy to contact, the adjacent ice bags are not easy to produce frozen adhesion, even if frozen adhesion occurs, the connecting force between the ice bags is small, and the ice bags are easy to separate, so that the probability of being torn during the separation of the ice bags is effectively avoided, and the repeated utilization rate of the ice bags is improved. The ice bag has simple structure and easy production and manufacture, and in addition, the ice bag can be used for cold accumulation and temperature reduction or heat accumulation and heat preservation.
In one embodiment of the present application, the opening ratio of the through-hole 20 on the envelope 11 is gradually decreased in a direction from the edge of the envelope 11 to the geometric center of the envelope 11. The opening ratio is the ratio of the total area of the holes on the plate to the area of the opening area (also called effective mass transfer area), i.e., [ phi ] ═ A0/Aa: Φ -open porosity (%) A0 is the total area of the holes on the plate (m 2); aa-the area of the open area (also known as the effective mass transfer area) (m 2).
The using method of the ice bag comprises the following steps: firstly, the ice bag is put in water, the ice bag is kneaded by hands to ensure that the water-absorbing cold-storage agent 30 absorbs water and expands, when the expanding water-absorbing cold-storage agent 30 expands to a proper state, the expanded ice bag is taken out and the moisture on the surface is wiped, and then the ice bag is put in a refrigerator for cold storage or microwave oven for heat storage.
Embodiments of the ice bag are described in detail below with reference to the accompanying drawings:
example one
As shown in fig. 1 and 2, the present application provides an ice pack including: a bag body 10 and a water-absorbing cold-storage agent 30.
As shown in fig. 1 and 2, the bag body 10 includes two envelopes 11, and the edges of the two envelopes 11 are connected in a sealing manner and enclose a containing cavity 14. As shown in fig. 3, a plurality of through holes 20 are provided in one envelope 11; the aperture of the through hole 20 gradually becomes smaller in the direction from the edge of the envelope 11 to the geometric center of the envelope 11. The envelope 11 comprises an outer surface 13 and an inner surface 12, the inner surface 12 being the surface of the envelope 11 enclosing the receiving cavity 14, and the outer surface 13 being the surface of the envelope 11 remote from the receiving cavity 14. In another embodiment of the present application, as shown in fig. 4, a plurality of through holes 20 are provided on both sheets of envelopes 11.
As shown in fig. 2, the water absorbing coolant 30 is disposed in the accommodating chamber 14.
As shown in figures 3 and 4, after the ice bag absorbs water, the whole ice bag is in an arc shape with a large middle part and small edges.
When the liquid seeps out of the water absorption cold storage agent 30 and flows to the outer surface of the ice bags from the through holes, because the edges of the ice bags are not easy to contact, the condition of freezing adhesion is not easy to generate between the adjacent ice bags, even if the freezing adhesion occurs, the connecting force between the ice bags is small, and the ice bags are easy to separate, thereby effectively avoiding the probability of being torn when the ice bags are separated, and improving the repeated utilization rate of the ice bags. The contact position of adjacent ice bags is mainly the middle part of the ice bag, therefore, the ice adhesion is more easily generated near the middle part of the ice bag, therefore, the arrangement mode of the through holes is adopted, and the ice adhesion is effectively avoided under the condition of ensuring the absorption speed of the ice bag.
In one embodiment of the present application, the aperture of the through-hole 20 is tapered in a direction from the outer surface 13 of the envelope 11 to the inner surface 12 of the envelope 11, as shown in fig. 5. In the process of water absorption of the ice bag, water flows from the outer surface 13 of the envelope 11 to the inner surface 12 of the envelope 11 through the through holes 20, the larger part of the aperture of the through holes 20 is an inlet of the water, and the smaller part of the aperture of the through holes 20 is an outlet of the water; the water is easy to enter the through hole 20 due to the larger aperture of the inlet, thereby ensuring the water absorption speed of the water absorption coolant 30; in addition, because the aperture of the through hole 20 at the outlet is smaller, water separated out from the water-absorbing coolant 30 is not easy to enter the through hole 20 from the outlet, so that the separation of water is effectively avoided, and further, freezing adhesion is effectively avoided.
In one embodiment of the present application, the water absorbing coolant 30 is a polymer water absorbent resin particle, and the particle size of the polymer water absorbent resin particle includes a plurality of kinds. The smaller the particle size of the high-molecular water-absorbent resin particles, the larger the specific surface area, the higher the surface energy and the larger the adsorption capacity; therefore, the polymeric water-absorbent resin particles with the particle size larger than 60 meshes account for more than 95% of the volume of the water-absorbing cold-storage agent 30, so that the water absorption capacity of the water-absorbing cold-storage agent 30 can be improved, and the cold-storage or heat-storage capacity of the ice bag can be improved.
In one embodiment of the present application, as shown in fig. 6, the area of the capsule 11 in which the through holes 20 are provided occupies at least one-half to two-thirds of the area of the capsule 11. The area of the coating film 11 provided with the through holes 20 is S1The surface of the envelope 11 on which the through-holes 20 are provided has an area S2；K＝S1/S2K is not less than 1/2 and not more than 2/3, if the area of the through holes 20 arranged on the envelope 11 is less than half of the area of the envelope 11, the water passing area is smaller, and the time for water to enter the bag body 10 through the through holes 20 is longer, so that the water absorption time of the water absorption cold storage agent 30 is longer. If the area of the through hole 20 arranged on the envelope 11 is larger than two thirds of the area of the envelope 11, the through hole 20 is arranged close to the middle part of the ice bag, so that the ice bag is easy to freeze and adhere. In the first of this applicationIn a preferred embodiment, the area of the through holes 20 is three-fifths of the area of the envelope 11.
As shown in fig. 6, in one embodiment of the present application, the plurality of through holes 20 constitute a plurality of rings, and the plurality of rings are sequentially nested; the through holes 20 of one ring are located between two adjacent through holes 20 of the ring adjacent to the ring.
In one embodiment of the present application, as shown in fig. 7, a hydrophobic layer 40 is provided on the outer surface 13 of the envelope 11. The water can form a water drop shape on the surface of the hydrophobic layer 40, and the water drop shape water cannot stay due to the arc-shaped outer surface 13 of the ice bag after water absorption, namely the outer surface 13 of the ice bag is anhydrous, and frozen adhesion cannot be generated in the process of freezing the ice bag.
In one embodiment of the present application, the distance between the two envelopes 11 is gradually reduced along the edge of the envelope 11 to the geometric center of the envelope 11, as shown in fig. 8. The messenger holds the accommodation space at chamber 14 middle part big, and it is little to hold chamber 14 accommodation space all around, and the cold-storage agent 30's that absorbs water content at ice bag middle part is high promptly, and the cold-storage agent 30's that absorbs water content at ice bag edge is low to the middle part that makes the ice bag after absorbing water can fully be the inflation, and the radian of the surface 13 of messenger's bag body 10 is bigger, further reduces the area of contact of the ice bag of two contacts.
Example two
As shown in fig. 9 and 10, the second embodiment is substantially the same as the first embodiment, and the description of the same parts is omitted, except that: the interval between the adjacent through holes 20 is gradually increased in the direction from the edge of the envelope 11 to the geometric center of the envelope 11. I.e. the number of openings per unit area decreases gradually in the direction from the edge of the envelope 11 to the geometric centre of the envelope 11.
When the liquid seeps out of the water absorption cold storage agent 30 and flows to the outer surface of the ice bags from the through holes, because the edges of the ice bags are not easy to contact, the condition of freezing adhesion is not easy to generate between the adjacent ice bags, even if the freezing adhesion occurs, the connecting force between the ice bags is small, and the ice bags are easy to separate, thereby effectively avoiding the probability of being torn when the ice bags are separated, and improving the repeated utilization rate of the ice bags. The contact position of adjacent ice bags is mainly the middle part of the ice bag, therefore, the ice adhesion is more easily generated near the middle part of the ice bag, therefore, the arrangement mode of the through holes is adopted, and the ice adhesion is effectively avoided under the condition of ensuring the absorption speed of the ice bag.
The following examples of several ice packs were tested for the performance of the freeze-proof connection, and the results of the performance tests are shown in table 1.
The test method comprises the following steps: soaking the ice bags in water to allow water to fully enter the ice bags, absorbing water by the high-molecular water-absorbing resin for expansion, taking out the expanded ice bags to dry the water on the surface when the expansion water-absorbing cold storage agent expands to a proper state, placing the two same ice bags in a refrigerator in a contact manner, freezing for the same time, observing the adhesion condition of the two ice bags, and testing the peeling force if the two ice bags are adhered.
Example 1
An ice bag comprises two envelopes and high polymer water-absorbent resin particles, wherein the middle parts of the two envelopes are provided with through holes, and the two envelopes are plastic envelopes. The area of the coating film provided with the through holes accounts for half of the area of the coating film. The high molecular water-absorbing resin particles with the particle size of more than 60 meshes account for more than 95 percent of the volume of the water-absorbing cold-storage agent.
Example 2
An ice bag comprises two envelopes and high polymer water-absorbent resin particles, wherein the outer surfaces of the two envelopes are all provided with through holes, and the two envelopes are plastic envelopes. The high molecular water-absorbing resin particles with the particle size of more than 60 meshes account for more than 95 percent of the volume of the water-absorbing cold-storage agent.
