Abstract

The utility model discloses a cushion bag with hydrogel sealed therein; both an upper sheet and a lower sheet of the cushion bag are formed by sequentially compounding a cloth, a plastic film and a non-woven fabric, wherein the cloth is made to be a bag surface, and the non-woven fabric is made to be a bag lining; hydrogel is uniformly adhered to the non-woven fabric; and the periphery of the cushion bag is sealed in a welding way, and the welding position is provided with a plastic welding strip. Once the hydrogel is heated or refrigerated, the cushion bag can store the heat or the coldness for a long period of time, so that the hydrogel which is sealed inside the cushion bag, not only can be used for heating, but also can be used for cooling down the air; moreover, the cushion bag has unique structure, and the hydrogel is very soft, so that the cushion bag is convenient and comfortable to use, is safe and durable to use and is widely applicable to different fields such as seat cushion, mattress, mouse pat, head cooling down and the like.

Description

Be sealed with the pad bag of hydrogel

Technical field

The utility model relates to daily necessities, particularly a kind of pad bag that is sealed with hydrogel.

Background technology

Heat accumulation articles for use such as existing hot-water bottle, electric blanket, it is warming to be used for pyrogenicity, enjoys the cool and can not be used for cooling, and it is made that hot-water bottle mostly is rubber, and the time will wear out slightly for a long time, need pour into hot water during use, not too convenient, electric blanket then needs to expend electric power, has potential safety hazard; Added hydrogel though have in a spot of pad bag product, structure is simple coarse too, and result of use is relatively poor, haves much room for improvement.

The utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of pad bag that is sealed with hydrogel is provided, but not only heat accumulation but also can protect cold, and it is comfortable to be easy to use, safety durable.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of pad bag that is sealed with hydrogel is provided, and two up and down of pad bag are cloth, plastic foil and nonwoven and are composited successively for three layers, and wherein cloth be a bag face, in nonwoven is bag; Evenly be stained with hydrogel on the nonwoven; The periphery of pad bag all seals by welding, and weld is added with the Plastic Welding bar.

The aforesaid pad bag that is sealed with hydrogel, the peripheral outer of pad bag is sewed with bound edge.

The above-mentioned pad bag that is sealed with hydrogel since in a single day hydrogel is heated or refrigeration after, can the long period heat accumulation or protect cool, so, it is sealed in the pad bag, it is warming both to have can be used for pyrogenicity, can be used for cooling again and enjoy the cool; And because the pad bag has particular structure, hydrogel itself is very soft, and because of a little, it is comfortable to be easy to use, and safety durable can be widely used in many aspects such as cushion, mattress, mouse pad, Head cooling.

Description of drawings

Below in conjunction with the drawings and specific embodiments structure of the present utility model and advantage are further described.

Fig. 1 is the front view of described utility model;

Fig. 2 be described utility model during not with bound edge B-B to cutaway view;

Fig. 3 is the vertical view of described utility model during not with bound edge.

The specific embodiment

Referring to Fig. 1-Fig. 3, provide a kind of pad bag that is sealed with hydrogel.Hydrogel is to be the gel of decentralized medium with water, can absorb and possess a large amount of water, because its energy long period heat accumulation or guarantor are cool, can be used for cold and hot conversion.This pad bag can only be that example describes with the rectangle for other shapes such as circular, ellipse, strip or tubulars also for square herein.Two up and down of pad bag, the cloth 1 that is cotton is composited for 3 three layers with plastic foil 2 and the nonwoven of PE, and wherein cloth 1 be a bag face, in nonwoven 3 is bag.The cloth here also can be other cloth, and plastic foil also can be PET or other plastic foil.Because the hydrogel water content is bigger, the effect of plastic foil 2 is that cloth 1 and hydrogel are isolated, and avoids soaking cloth 1 and causes and can't use, and can make hydrogel keep moisture simultaneously again, avoids water loss.Evenly be stained with hydrogel 4 on the nonwoven 3.The periphery of pad bag all seals by ultrasonic bonding, and weld is added with TPU Plastic Welding bar 5, or other hot melt such as PU, PE Plastic Welding bar preferably, to guarantee welding effect.Certainly, as long as can reach good welding effect, also can not add the welding bar during welding.When making the pad bag, be that three side welds that will fill up bag earlier connect sealing, the hydrogel that will be added with curing agent is again poured in the bag from opening, weld opening then, pressing pad bag again, like this, the hydrogel 4 of the moving shape of semi-fluid sticks on the nonwoven 3, when the user forced in the pad bag, hydrogel 4 was squeezed, and major part is still stayed the position that is squeezed, fraction then is pressed towards the periphery of the position that is squeezed, but, can continue to use repeatedly because the elasticity of hydrogel and the adhesive attraction of nonwoven 3 stop to push back hydrogel 4 and promptly restore to the original state.

Referring to Fig. 1, the peripheral outer of pad bag is sewed with bound edge 5, better appearance.

The foregoing description is a preferred embodiment of the present utility model, and all and the similar structure of the utility model and the equivalence of being done change, and all should belong to protection category of the present utility model.
