Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a medicine can with excellent thermal efficiency, such as a medicine can.

[Conventional technology]

Traditional medicine cans usually have rounded or flat bottoms, but when placed on a gas stove etc. and lit, the center of the gas stove has less air than the periphery. There was a tendency for the supply amount to decrease and the combustion efficiency to decrease.

Additionally, heated air evaporates from around the bottom of the medicine can along the sides of the medicine can, and this tendency is particularly noticeable in medicine cans with rounded bottoms.

[Problem that the invention attempts to solve]

This idea was developed from the viewpoint of energy saving, because when a medicine can is placed on a gas stove, etc. and ignited, the combustion efficiency tends to be lower in the center of the gas stove compared to the periphery, and the heated air is not fully utilized and evaporates. This was done in an attempt to eliminate the problem.

[Means to solve the problem]

This idea is to provide an exhaust tube inside the medicine can body with one end opening at the center of the bottom and the other end reaching inside the lid, and the lid has a plurality of exhaust holes connected to the side along the periphery of the lid. A bottom plate extending from the lower end of the circumferential side and having a hole for fitting the exhaust, etc. in the center is provided, and the lid is placed so as to keep a small distance from the periphery of the upper opening of the medicine can body, and the heated air is heated. The problem was solved by actively introducing air into the exhaust pipe, and the heated air that reached the inside of the lid from the exhaust pipe passed through the exhaust hole and flowed out through the gap between the lid and the main body of the medicine can.

[Effect]

The medicine can of this invention is provided inside the medicine can body.
Heated air is introduced into an exhaust pipe with one end opening at the center of the bottom and the other end reaching the inside of the lid, and the heated air passes through the inside of the medicine can lid and flows out from the gap between the lid and the medicine can body. This not only increases the combustion efficiency in the center of the gas stove, but also further increases the heating efficiency of the liquid contained in the medicine can body by the heated air passing through the exhaust pipe and the inner surface of the lid. It has the effect of reducing air volatilization.

〔Example〕

An embodiment of the medicine can of this invention will be described with reference to the drawings.

1 to 4 are diagrams showing the external appearance of the medicine can of this invention, in which 1 is the medicine can body, 2 is the outlet for liquid such as water stored in the medicine can body 1, and 3 is the handle. , 4
is the lid, and 5 is the knob of the lid 4. As shown in FIGS. 4 and 5, in the center of the bottom 6 of the medicine can body 1, an exhaust pipe 8 is provided which has an opening 7 in the bottom 6 and faces into the inside of the medicine can body 1. , its tip is lid 4
reaches inside. Further, on the periphery of the upper opening of the medicine can body 1, there is an upwardly facing stepped portion 9 on which the lid 4 is placed.
is formed. Furthermore, as shown in FIGS. 5 and 6, the lid 4 having the knob 5 has a circumferential side portion 11 having a downward step 10 on the lower edge, and a hole 12 for fitting the exhaust pipe 8 in the center. A bottom plate 13 extending from the circumferential side part 11 is provided, and the medicine can body 1
A downwardly facing step 10 of the lid 4 is placed on an upwardly facing step 9 provided at the periphery of the upper opening of the lid 4 to cover the main body of the medicine can. Also, the peripheral side part 11
A plurality of exhaust holes 14 are arranged in series.

Now, store an appropriate liquid such as water in the medicine can body 1,
When placed on a gas stove and ignited to heat it, the heated air rises through the exhaust pipe 8 that opens at the center of the bottom of the medicine can main body 1, so air from the gas stove and the periphery of the medicine can is sucked in and the air is heated up at the center of the gas stove. supply to,
In addition to increasing the combustion efficiency in the center of the gas stove, the high-temperature heated air rising up the exhaust stack 8 fills the inner surface of the lid 4 while heating the wall of the exhaust stack 8, and the filled high-temperature air heats the bottom plate 13 while discharging the surrounding side surface. The gap 1 between the medicine can body 1 and the lid 4 through the exhaust hole 14 of the part 11
5 and evaporates to the outside.

Also, when the vapor pressure inside the medicine can body 1 increases as heating progresses, the pressure pushes up the lid 4 and closes the gap formed between the upward step 9 and the downward step 10. Release steam to the outside.

Although the exhaust pipe 8 is illustrated as having a cylindrical shape, it is not necessarily limited to this. For example, it may have a truncated conical shape, or it may have a truncated conical shape, or it may have a truncated conical shape, or may have a truncated conical shape, or may have a cylindrical shape to increase the contact area with the liquid and increase thermal efficiency. , the wall surface of the exhaust pipe may be a so-called bellows-shaped bent surface, and the bottom plate 1
It goes without saying that 3 may be a horizontal plate instead of the illustrated funnel-shaped inclined plate.

[Effect of idea]

As described above in detail, the medicine can of this invention is provided with an exhaust pipe inside the medicine can body, one end of which opens at the center of the bottom, and the other end of which reaches the inside of the lid, and the lid has a side surface along its periphery. is provided with a circumferential side surface having a plurality of exhaust holes arranged in series, and a bottom plate extending from the lower end of the circumferential side and having a hole for fitting the exhaust pipe in the center, and the lid is connected to the upper opening circumference of the medicine can body. Because they are placed at very small intervals, when a liquid such as water is stored inside the medicine can and placed on a gas stove to ignite and heat it,
As the heated air rises through the exhaust pipe that opens at the center of the bottom of the medicine can, the air around the gas stove and the medicine can is sucked into the center of the gas stove, increasing the combustion efficiency of the central part of the gas stove and causing the exhaust pipe to open. The rising high-temperature heated air fills the inner surface of the lid while heating the wall of the exhaust stack, and the filled high-temperature air further heats the bottom plate. Therefore, the liquid contained in the medicine can is efficiently heated not only by heating from the bottom of the medicine can by the gas stove, but also by heat radiation from the exhaust pipe heated by high-temperature heated air and heat radiation from the bottom plate. Compared to conventional medicine cans, it takes less time to reach the same temperature, resulting in an energy-saving effect.
