Abstract

The utility model relates to a cold keeping bag which has a plastic bag body whose inner part contains cold keeping powder with high molecular polymer. A check valve bag with barb weld lines is arranged at the calabash-shaped central point which is arranged at the water inlet above the bag body; the water is injected from the inlet and flows into the bag through the check valve bag; when the pasty cryogen which is combined with the cold keeping powder is arranged in the bag body by flatly lying or reversely lying, the check valve bag which is oppressed through the water pressure of the cryogen makes the bag slot closed; so the cryogen can not independently close the check valve bag to make the bag slot ooze and after the water enter the bag body, the full check effect is achieved.

Description

Cold keeping bag

The utility model is about a kind of cold-keeping bag, especially a kind of cold-keeping bag that utilizes the macromolecule water uptake polymer as cold-retaining agent.

For the subtropical climate area, temperature is generally higher, cause depositing of food difficult, need rely on making of refrigerator fully and be used for the freshness of long preservation food, avoid Yin Wendu too high and addle, yet be not that each place all has the supply of power supply or the setting of refrigerator, as the transportation of moving of marine products, when cockout or fishing, often remoter because of distance, spend the long time to arrive, so the preservation particular importance of food.Usually people are away from home no refrigerator but need keep lower temperature the time, all can be in advance prior to before going out water being congealed into ice packagedly to go in the incubator with refrigerator, insert in the incubator to reach the effect of iced storage desiring to hold the article of icing temperature again.Though yet use ice cube can temporarily keep the freshness and the ice-cold degree of food, it uses following listed shortcoming:

First, because ice cube is to utilize water, it is freezingly reduced to below 0 ℃ and congeal into ice, therefore need only one and leave freezing space, promptly can return to the state of water at short notice along with the higher temperature in the external world, both made in incubator and also can't obtain long freezing point temperature, made an addition in the incubator, very trouble and uneconomical so need often buy ice cube.

The second, when using the ice cube chilled goods, after it dissolved into water gradually along with the increase of time, as easy as rolling off a log infiltration food was interior or cause interior dirty the wetting of incubator, causes the unclean and pollution incubator of food, and its hygiene effect has problem.

For this reason, the purpose of this utility model is to propose a kind of cold-keeping bag, and it has overcome the above-mentioned shortcoming with the ice cube cold insulation, and has the long cold insulation time.

The purpose of this utility model is to realize like this, a kind of cold-keeping bag promptly is provided, it comprises a cold insulation bag and a check (non-return) valve bag, this cold insulation bag is the plastics bag-like container of a sealing, bag inside is loaded with the absorbent polymer polymer, after suction, promptly become refrigerant, and be provided with a water inlet at cold-keeping bag top center place, this check (non-return) valve bag is a saturating empty small plastic bag, its top slightly bottom center place cooperates cold insulation bag water inlet to be provided with a water inlet, and bag is as the cucurbit shape, has both sides down to extend to the bottom and central authorities have a melt run of barb; This check (non-return) valve is arranged on the cold-keeping bag inner and upper, and is fixing via the water inlet both sides and the cold-keeping bag fusion of valve bag.

Utilize the cold insulation pulvis of macromolecule water uptake polymer according to cold-keeping bag of the present utility model, meeting is expanded and is become refrigerant after adding water, therefore have when using in freezing back and directly expose to the open air in the air more than five hours, and place the time cold storage effect that to keep in the incubator more than 12 hours.

The water inlet place of cold-keeping bag of the present utility model is set to the check (non-return) valve bag that a tool cucurbit shape centre has barb, after water is poured into by the valve bag, can combine expansion with the cold insulation pulvis and form pasty state, make its molecular change big, when water keeps flat or stands upside down, can oppress the valve bag on the other hand in cold-keeping bag and make it driving fit by hydraulic pressure, so bigger refrigerant molecule promptly can't infiltrate in the valve bag of driving fit, reaches water and pours into back non-return effect fully.

Since cold-keeping bag of the present utility model water pour into the back the container of a sealing, therefore no matter freeze or the process of dissolving in neither have current lose and cause dirtyly wet, the puzzlement of contaminated food products, be a very design of safe and sanitary.

Below, will be explained in detail the utility model in conjunction with the accompanying drawings, in the accompanying drawing:

Fig. 1 is the schematic perspective view of the utility model cold-keeping bag;

Fig. 2 is the front view of the utility model cold-keeping bag;

Fig. 3 is the solid combination schematic diagram of the utility model cold-keeping bag.

Cold-keeping bag of the present utility model is to be formed by a

cold insulation bag

1 and 12 fusions of check (non-return) valve bag.Cold-keeping bag 1 is the plastics bag-like container of a sealing, and bag inside is loaded with absorbent polymer polymer 13, and it promptly becomes refrigerant after suction.Be provided with a little opening at the top center place of cold-keeping bag, the water inlet 122 when injecting for water.Check (non-return) valve bag 12 is a saturating empty small plastic bag, and its top slightly bottom center position cooperates cold insulation bag water inlet 122 places that one little opening, the water inlet when entering for water are arranged.Check (non-return) valve bag bag is as the cucurbit shape, has both sides down to extend to the bottom and central authorities have the melt run 121 of barb 1211, and the bag seam 123 of water between melt run 121 and line flowed in the cold-keeping bags.

According to above structure, check (non-return) valve bag 12 is arranged at cold insulation bag 1 inner and upper, and is fixing via water inlet 122 both sides and 1 fusion of cold insulation bag of valve bag upper limb.When it is implemented, earlier the water inlet 122 of water from cold-keeping bag 1 is injected in right amount, and the water of injection can be by the refrigerant that forms pasty state that cold insulation pulvis 13 absorbs in bag, when cold-keeping bag 1 kept flat or stands upside down, the hydraulic pressure compressing check (non-return) valve bag 12 by refrigerant can make 12 driving fits of valve bag, and the bag seam 123 at 12 bags of body melt runs of valve bag, 121 routine hooks, 1211 places is less, after compressing, definitely can't make the water infiltrate, so water promptly is closed in the bag after entering cold-keeping bag 1 inside, can not flow out.After so will adorning the cold-keeping bag 1 freezing taking-up of water again, get final product chilled food, because the relation of refrigerant, freezing cold-keeping bag 1 can be kept for a long time and not and can dissolve rapidly, makes it reach the practical and economic effect of health.
