Abstract
The utility model discloses a can device capable of automatic heating or cooling, which is composed of a cylinder which can be filled with an automatic heating source or an automatic cooling source, an easy-pull opening cover and a bottom cover arranged at the bottom of the cylinder, and the cylinder is sealed and connected with the outer side of an inner cup with an easy-pull top. When the utility model is used, little water is added after the bottom cover is removed and the easy-pull opening cover is opened, reagent in an interlayer reacts, and foodstuffs or beverages in a can are sufficiently heated or cooled a few minutes later. The utility model has the advantages of easy use and very safe preservation.
Description
The utility model relates to a kind of food and drink can, is specifically related to the can of a kind of automatic heating or cooling.
When people go on business in tourism, due to limited conditions, can't heat or cool off, particularly garrison the sentry in the world of ice and snow the tinned food beverage, being laid off that the back wishes to obtain can autotermic food, and drink is cold beverage and the soldier of patrol in the South Sinkiang thirsts for having promptly.Chinese patent CN87200233 has disclosed a kind of self-heated can, and its structure is comparatively complicated, also need light temperature booster, and is not too economical and practical.Chinese patent CN86200709 has disclosed a kind of device of the can of heating automatically, two kinds of different reagent are housed, in the container when the needs canned food, with two kinds of reagent contacts, the chemical reaction heat that takes place heats can, and it causes easily in transportation and storage process and isolates invalid and heating voluntarily.Chinese patent CN87201740 has disclosed a kind of fast chilling device for easy-opened beverage can, employing absorbs the can heat with the throttling effect that cooling material expansion under the compressive state discharges, to reach cooling purpose rapidly, therefore require the withstand voltage and good sealing of easy open can, thereby increased cost and made requirement.
For this reason, the utility model provides a kind of easy to make, the automatic heating of excellent performance or the can of cooling.
Above-mentioned purpose of the present utility model realizes in the following manner: the can of a kind of automatic heating or cooling, but comprise by the outside being tightly connected and the spontaneous thermal source of filling or, and described cylinder bottom is provided with easy-to-draw unlatching lid and with the sealing bottom from the cylinder of cooling source with the interior cup of band easy-open lid.
It is characterized in that described spontaneous thermal source is selected from the compound of calcium oxide or calcium oxide and powdered carbon, the described compound that is selected from potassium nitrite and potassium nitrate or sodium nitrite and sodium nitrate from cooling source.
The utility model has the advantages that significantly, the cylinder of cup can be through cold stamping shaped easy to make, with low cost in the band.When needs are drunk, as long as open bottom, draw back easy-to-draw unlatching lid and charge into low amounts of water, the reagent in the interlayer reacts, and after a few minutes, the Foods or drinks in the can obtains sufficient heating and cooling, uses very conveniently, and preservation is also very safe.
The utility model is described in further detail below with reference to drawings and Examples.
Fig. 1: be birds-eye view of the present utility model, and
Fig. 2: for Figure 1A-A to generalized section.Embodiment 1:
As depicted in figs. 1 and 2, the cylinder 4 of the filling calcium oxide 3 that the utility model is tightly connected by the outside with the interior cup 1 of band easy-open lid 2, and described cylinder 4 is provided with easy-to-draw unlatching lid 5 and plastic bottom cover 6 constitutes.Embodiment 2:
Repeat the structure of embodiment 1, the cylinder 4 of the filling powdered carbon that the utility model is tightly connected by the outside with the interior cup 1 of band easy-open lid 2 and the compound 3 of calcium oxide, and described cylinder 4 is provided with easy-to-draw unlatching lid 5 and plastic bottom cover 6 constitutes.Embodiment 3:
Structure is identical with embodiment 1 and 2, but the filling potassium nitrite that is tightly connected by the outside and the cylinder 4 of sodium nitrate mixture 3 with the interior cup 1 of band easy-open lid 2, and described cylinder 4 is provided with easy-to-draw unlatching lid 5 and bottom 6 constitutes.
As long as remove bottom during use and open easy-to-draw unlatching lid 5, add a spot of water, the reagent in the interlayer reacts, and the food after a few minutes in the can is fully heated or is cooled off, and uses very convenient.
The foregoing description only for illustrative purposes, protection domain of the present utility model will embody in claims.
Claims (2)
1. automatic can of heating or cooling, but it is characterized in that the spontaneous thermal source of filling that is tightly connected by the outside or from the cylinder of cooling source with the interior cup of band easy-open lid, and described cylinder bottom is provided with easy-to-draw unlatching lid and bottom lid.
2. the can of automatic heating as claimed in claim 1 or cooling, it is characterized in that described automatic heating source is selected from calcium oxide or calcium oxide and powdered carbon compound, and cooling source is selected from the compound of potassium nitrite and potassium nitrate or the compound of sodium nitrite and sodium nitrate automatically.
