Description
Technical Field
The invention relates to the technical field of a warmer, in particular to a non-woven fabric inner bag for the warmer.
Background
The reaction principle of the warm patch is that the oxidation reaction speed is accelerated by using a primary battery, and chemical energy is converted into heat energy. In order to enable the temperature to last longer, the mineral material vermiculite is used for heat preservation. The bag material is special because the reaction can not occur before the use, and the bag material consists of a raw material layer, a gelatin layer and a non-woven bag. The non-woven bag is made of microporous permeable membrane, and has a conventional air-impermeable outer bag. When in use, the outer bag is removed, the inner bag (non-woven bag) is exposed in the air, and oxygen in the air enters the inner bag through the air-permeable film. The time and temperature of the exotherm are controlled by the oxygen transmission rate of the gas permeable membrane. If the oxygen permeation is too rapid, heat is given off at a moment and the skin may be scalded. If the oxygen permeation is too slow, there is nothing to do.
Disclosure of Invention
The purpose of the invention is: overcomes the defects in the prior art and provides a non-woven fabric inner bag for a warmer with moderate oxygen permeation speed.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
the utility model provides a non-woven fabrics inner bag for warm baby, includes first layer inner bag and second floor inner bag, connect through a plurality of gluing piece between first layer inner bag and the second floor in situ bag, equidistant setting between a plurality of gluing piece, the thickness of gluing piece is 1-1.5mm, the internal surface of first layer inner bag and second floor inner bag is provided with one deck thin layer respectively, it has a plurality of bleeder vents to open on the thin layer, bleeder vent on the first inner bag layer and the bleeder vent on the second floor in situ bag set up in turn.
Furthermore, the aperture of the air holes on the inner bag of the first layer is larger than that of the air holes on the inner bag of the second layer.
Further, the distance between the inner bag of the first layer and the inner bag of the second layer is 1-1.5 mm.
Furthermore, the number of the air holes in the inner bag of the first layer is smaller than that of the air holes in the inner bag of the second layer.
Further, the thickness of the first layer inner bag is 0.2-0.5 mm.
Further, the thickness of the inner bag of the second layer is 0.3-0.5 mm.
Furthermore, the first layer inner bag, the second layer inner bag and the film layer are connected through a hot melting method.
The technical scheme adopted by the invention has the beneficial effects that:
the non-woven fabric inner bag for the warmer comprises a first layer inner bag and a second layer inner bag, wherein the first layer inner bag and the second layer inner bag are connected through a plurality of adhesive blocks which are arranged at equal intervals, the thickness of each adhesive block is 1-1.5mm, a thin film layer is respectively arranged on the inner surfaces of the first layer inner bag and the second layer inner bag, a plurality of air holes are formed in the thin film layer, and the air holes in the first layer inner bag and the air holes in the second layer inner bag are alternately arranged.
