Abstract

The utility model relates to the structural improvement of a can daily used for carrying and storing food. The interior of the novel can body is divided into three layers, wherein, the lower layer is calcium oxide, the middle layer is a sealed plastic water bag, and the upper layer is food containing can. The three layers are respectively spaced by wire frames. A bore spine is arranged in an outward convex bulge at the inward concave bottom center of the can body. The bottom bulge is inward pushed, and the bore spine moves up and passes through the gaps of the wire frames for puncturing the water bag. The outflow water is mixed with calcium oxide for producing chemical reaction. Thus, heat is discharged for heating the food. The utility model has the advantages of safe and convenient operation, time saving and no pollution. The utility model is suitable for high altitude and ultra cold areas, cold seasons, field operations, army camps, travel picnics, etc.

Description

Automatic heating can

The utility model relates to the daily used structural development of carrying, store the food beverage can.

Existing bread and cheese can just can carry fresh-keeping and stores food, but at winter or high height above sea level, extremely frigid zones, for field man and traveller, will bring inconvenience when edible.

The purpose of this utility model is to provide a kind of external energy that need not, and self heats can efficiently.

The utility model is to realize like this.Utilize the heat-producing chemical principle of calcium oxide and water, make jar interior food obtain heating.The structure of this self-heating type can is: whole can body has an openable loam cake, and the bottom is a double bottom, and the outer bottom in lower end also can be opened, and only conduct prevents to bump at the bottom of the internal layer by mistake, and causes the usefulness of chemical reaction.When whole can was circle, enclosing cover was a unscrewing type up and down; When its when being square, enclosing cover is the riveted joint biting connecions up and down.Lower end internal layer sealed bottom is for concaving, and core has a taper acupuncture to evagination in its evagination center, bottom.Correct riveting under the bore spine outside in the sunken bottom portion, refer in bore spine is vertical.Divide three layers in the box body, calcium oxide is placed by its lower floor, and the sealed plastic water bag is placed in the middle level, and the upper strata is for depositing thing jar box, and the centre is separated by rack respectively.Food pot box profile is less than outer box.Between isolating, rack leaves the space, the passage that a large amount of water vapours overflow during as reaction.Food pot box cover middle part evagination can just in time coincide mutually with the middle protuberance of building loam cake.Like this, the food pot box just can have been located wherein.At the concavo-convex bottom of can body internal layer bore spine placed around calcium oxide, a rack is arranged thereon, rack is a little more than the bore spine tip, in the middle of the rack space is arranged, can make bore spine pass rack, one sealed plastic water bag is arranged in the rack pop-up, one rack is arranged on water bag, and holder has the food pot box above the rack.During the desire heating, only need open loam cake, but not take down, open the outer bottom in lower end again, inwardly press the bulge part that protrude the tin can bottom with hand, its inner bore spine also rises thereupon, space by in the middle of the rack between water bag and calcium oxide punctures water bag, and water is overflowed.Water and calcium oxide promptly produce chemical reaction.Along with reaction aggravation gradually, temperature build-up, plastic water bag melts, and water all flows out, and makes reaction more abundant.In short a few minutes, temperature just can rise to 200 ℃, is enough to food in the heating tank.

This heating can utilizes calcium oxide and hydrate to discharge the reaction of a large amount of heat energy, comes heat food.Reaction time is very short, does not influence normal edible after the heating.Course of reaction is finished in jar, the flames of anger, need not add non-productive operation or additional source of energy, safe in utilization, save time, facility.Especially in winter, more will demonstrate its effect.In addition, in high height above sea level anoxic area, this from heating also practicality more of can.Because of have need not comburant oxygen just, its adaptive surface also will enlarge, promptly regardless of being that army camps, field work; still tourism picnic; because of need not the additional combustion energy and material, also relative having played reduce pollute, the effect of protection environment, this will bring very big facility.Its structure can be designed to one-shot usage or repeatability use according to different needs.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is according to the section-drawing that heats can certainly that the utility model proposes.

Describe details and service condition in detail below in conjunction with Fig. 1 according to the concrete device that the utility model proposes.

This structure comprises a can body (1), loam cake (2), the concavo-convex sealed bottom of internal layer (3), bore spine (4), calcium oxide (5), plastic water bag (6), contains to isolate between food pot box (7), water bag and the calcium oxide and support to isolate between rack (8), water bag and the food pot box rack (9), bottom protection enclosing cover (10).

Open loam cake (2); but do not take down; open bottom protection enclosing cover (10) again; with the hand bulge part that inwardly protrude (3) bottom jar box (1); it is inwardly flatly advanced; at this moment because bore spine (4) rising in its bulge; pass rack (8) space, puncture sealed water bag (6), because of gravity water overflows; promptly produce chemical reaction with calcium oxide (5); and aggravation heats up gradually, and food or beverage in jar box (7) fully are heated, and opens the loam cake of a jar box (1); open the upper cover of food pot box (7) again, just edible.

Claims

1, a kind of from heating can, utilize the chemical principle of calcium oxide and aquation symphysis heat, jar interior food is heated, the loam cake (2) that it is characterized in that can body (1) is an openable, the bottom is a double bottom, it is the also openable bottom of skin (10), the jar concavo-convex bottom of internal layer, the end (3) concaves, and the centre bottom evagination, at evagination center, bottom, its (3) one bore spine (4) is arranged, bore spine corrects riveting thereon under (4), refer in bore spine (4) is vertical, divide three layers in the box, its lower floor's bore spine (4) placed around calcium oxide (5), have one to isolate support rack (8) between calcium oxide and the top water bag (6), contain on water bag (6) and top also has one to isolate support rack (8) between the food pot box (7).
