Abstract
The invention discloses a thermal bag self-heating, which comprises an airtight external bag, an internal bag. The internal bag is sealed in the external bag, which is provided with micro breather holes on surface and is internally sealed with at least one layer of slice-shaped self-heating agent; the self-heating agent is made of the following ingredients: ferrous powder, active carbon, salt, plant fibre, glutin and water. The invention resolves the problems as ash leakage, dropping and unevenness existed in the prior art, which has the advantages of flatness, good handle, long time for heating, reliable and gentle temperature, low requirements on package and simple fabrication.
Description
Technical field
The present invention relates to a kind of warm bag.
Background technology
Occurred a variety of spontaneous heating thermal bags easily in recent years, and be generally by chip and trigger the reusable spontaneous heating thermal bag of acetic acid type of crystallization heat release and be two kinds of forms of disposable spontaneous heating thermal bag of host with the iron powder.The warm bag raw material that with the iron powder is host mainly is an iron powder, heat release when utilizing ferrum generation oxidation reaction produces heat, as application number is 200410006553,03129979,200420024875,200510084177,98251120,200420029642,200410067117,98114308,97108171,02149133 Chinese patent, the raw material of above-mentioned disposable spontaneous heating thermal bag is powder or graininess, but because oxidation reaction needs airborne oxygen, all need air-vent on the inner bag, allow oxygen and iron powder react, the general pinpricks that adopt of air-vent more, the self-generating exothermal agent powder is loose in addition, easily in inner bag, move, the warm containing of making is prone to Lou ash, weigh down material, assembling injustice represents and resembles, use very inconvenient, and the pinprick aperture is bigger, the amount that oxygen enters inner bag is big, self-generating exothermal agent granule gap is full of oxygen, cause oxidation reaction speed fast, caloric value height in short-term, and shortened warm bag service time, therefore, improve above-mentioned situation, packaging material are required just high, a kind of method of solution is to use the micro-porous permeable thin film, but the price of this kind thin film is higher, causes warm bag manufacturing cost height.In addition, the gathering of self-generating exothermal agent powder easily causes amount of localized heat to assemble and forms the bag that expands, and influences result of use.
Summary of the invention
The technical problem to be solved in the present invention provide a kind of easy to use, heating is stable lasting, do not have the ash of leakage, equatorial warm bag.
The present invention solves above-mentioned technical problem by the following technical solutions: a kind of spontaneous heating thermal bag, comprise air-locked outer bag, inner bag, it is inner that inner bag is sealed in outer bag, inner bag surfaces is provided with ventilative micropore, encapsulate one deck lamellar self-generating exothermal agent at least in the inner bag, the lamellar self-generating exothermal agent is made by following raw material: iron powder, active carbon, Sal, Plant fiber, gelatin and water.
The lamellar self-generating exothermal agent is made by the raw material of following parts by weight: iron powder 40-75, active carbon 5-15, Sal 3-5, Plant fiber 10-20, gelatin 1-5, water 15-25.
Be pasted with medicament layer and/or adhesive-layer on the inner bag lateral surface, medicament layer, adhesive-layer are provided with protecting film outward.
Stack 1～6 layer lamellar self-generating exothermal agent in the inner bag.
The inner bag ventilative bag that cast film, composite membrane or non-woven fabrics with micropore or pin hole made of serving as reasons, the airtight bag that outer bag is made for polyethylene, polypropylene, polyamide, polyethylene terephthalate or aluminum-plastic composite membrane.
The preparation method of spontaneous heating thermal bag is: at first iron powder, active carbon, Sal, Plant fiber are mixed, then the water-soluble back of gelatin is added in the above-mentioned compound, after stirring, be pressed into lamellar, making the lamellar spontaneous heating stings together, the lamellar self-generating exothermal agent is encapsulated in the inner bag, then, inner bag is encapsulated in the outer bag.
The Plant fiber is cotton fiber, flaxen fiber or paper pulp fiber, and fibre length is no more than 1 centimetre, diameter and is no more than 8.
The present invention adopts and makes flaky self-generating exothermal agent, solved and leaked ash in the prior art, tenesmus, phenomenon such as not open and flat, iron powder is evenly distributed in the lamellar self-generating exothermal agent, and the multilamellar self-generating exothermal agent stacks, the slit is arranged between each layer, guarantee that iron powder contacts evenly reacting balance with oxygen, longer duration, use common pin hole breathable packaging material can not only reduce complicated production link and manually but also reduced the packaging material requirement, save cost, the warm bag of the present invention is open and flat, good hand touch, collapsible, practicality easy to carry, the persistent fever time is long, and temperature stabilization is gentle, externally packing instructions are not high, make simple.
In the lamellar self-generating exothermal agent, oxidation reaction can take place in iron powder, water and oxygen, produces heat; The effect of active carbon is an adsorption of oxygen; Sal is catalyst, accelerates the oxidation reaction of iron powder; The Plant fiber plays the effect of connection and support frame among powders such as iron powder, active carbon, Sal, in addition, fiber absorbs moisture becomes the carrier of water, can not cause material too moist because of adding moisture, and in oxidation reaction, play the effect of moisture slow release, the assurance oxidation reaction is steadily carried out, and makes warm bag longer service time; Gelatin plays the effect of gluing, molding bonded, makes iron powder, active carbon, Sal and Plant fiber's bonding, is pressed into lamellar easily, and keeps this shape in use, does not scatter.
Warm bag can be made warm pocket facing as required, warm pocket facing is that warm inner bag one side is provided with adhesive-layer or has the medicament with therapeutical effect, directly be attached to certain position of health, can carry out medical hot compress, be mainly used in expelling wind and cold, relaxing muscles and tendons to promote blood circulation, reducing swelling and alleviating pain, women's dysmenorrhoea etc., can also be used for the heating of winter or severe cold area.

The specific embodiment
The preparation method of spontaneous heating thermal bag in the foregoing description: with raw material reduced iron powder, active carbon, Sal, Plant fiber, mix, after then gelatin being sprayed on after water-soluble in the compound of iron powder, Sal, Plant fiber and activated carbon after the stirring, stirring, send into and roll the different-thickness sheet material in the tablet machine, difformity, specification are cut, struck out to size as requested, the lamellar self-generating exothermal agent is encapsulated in the inner bag, then, inner bag is encapsulated in the outer bag.
The contrast experiment: with 40g/ bag specification is example.
Experimental procedure: when 25 ℃ of room temperatures; get the warm bag of lamellar exothermic mixture and warm each bag of bag of ordinary powder material of the embodiment of the invention 1; tear outer bag; lie on the cotton towel after four layers of the doublings; is range that 100 ℃ thermometer is placed in the middle of warm bag and the towel, observes variation of temperature, per half an hour record once; until temperature rise earlier, after reduce to till 40 ℃, add up the lasting total time of heating that cools to 40 ℃ from 40 ℃ of intensifications then.
Be illustrated in figure 6 as the present invention and common warm bag heating effect comparison diagram, the present invention's (25 ℃ time) under ambient temperature conditions, when the heating maximum temperature was 68 ℃, flaky warm bag persistent fever was more than 12 hours, and the fever time of ordinary powder material is 8-9 hour.
