Description

Tailless thermos bottle and preparation method thereof

Technical field

The invention relates to the technical field of an insulated container, in particular to a tailless thermos bottle and a preparation method thereof.

Background technique

The thermos bottle is also called a thermos bottle. The double-walled bottle with vacuum inside is the inner tank, and the insulated container made of the outer casing is the most common daily necessities. Thermos are widely used for storing hot water, cold drinks and medicines. The thermos consists of a liner, outer casing and additional components. The inner tank is composed of two glass bottles inside and outside. The two are connected at the mouth of the bottle, and the gap between the two bottles is vacuumed to weaken the heat convection. The surface of the glass bottle is plated with a bright silver film to reflect the infrared heat radiation. When the temperature inside the bottle is high, the heat energy of the contents is not radiated outward; when the bottle is cold, the heat outside the bottle is not radiated into the bottle. The thermos effectively controls the three heat transfer paths of conduction, heat convection and radiation. The main component that plays a role in heat preservation in the thermos bottle is the internal thermos bottle. The daily use of the thermos bottle usually has a tail pipe at the bottom, and the vacuum of the two glass bottle wall interlayers is extracted through the tail pipe, if the interlayer is Gradually inflating or damaging the sealed small tail, destroying the vacuum state of the interlayer, the thermal insulation bottle loses the insulation performance. At present, because the tail pipe of the thermos bottle protrudes outside the thermos bottle, the wall of the tail pipe is very thin, which easily leads to the special damage of the tail pipe part during transportation, assembly and use, and the tail pipe is damaged. There is no heat preservation effect of the post-insulation bile, so how to solve this problem is particularly important.

Summary of the invention

The object of the present invention is to provide a tailless thermos flask and a preparation method thereof, which can effectively solve the problems in the background art.

In order to achieve the above object, the present invention provides the following technical solution: a tailless thermos bottle, including a liner and a bladder, a first insulation layer on the outer side of the inner liner and a second insulation layer on the inner wall of the outer bladder. The gap between the inner liner and the outer bladder is provided with more than one silicone pad from top to bottom, a sponge layer is arranged at the bottom between the inner liner and the outer bladder, and a gypsum is arranged at the bottom end of the outer bladder. In the outer jacket of the outer bladder, there is a clay pot.

Further, preferably, the silica gel mat has a total of three and is disposed at intervals.

Further, preferably, a gypsum layer is provided between the inner and outer bladder mouths.

Further, preferably, a groove is provided on the outer side of the outer bladder.

The invention also discloses a preparation method of a tailless thermos bottle, the specific steps of which are as follows:

Step 1. First make a thermos liner, and apply a layer of thermal insulation material to the inner liner;

Step 2: inserting a silicone pad on the outer and outer sides of the inner liner prepared in step 1;

Step 3, then making the outer bladder, and leaving a gap between the outer bladder and the inner liner, and then vacuuming the thermos bottle, pulling out a tail tube shrinking mouth when vacuuming and sealing, and the tail tube shrinks The length of the mouth is kept within 5cm;

Step 4. When the outer casing is processed to shrink the tail pipe, the tail pipe is continuously heated in a flame of 200-350 ° C and rapidly heated, and then the tail pipe is slowly contracted to become a tail pipe of a trapezoidal structure;

Step 5, continue to raise the temperature to 550-600 ° C, so that when the tail pipe shrinks to a pore size of 20 cm, the temperature will be raised to 850 ° C, then the gypsum is melted and placed on the tail pipe mouth, and then the cooling seals the tail pipe mouth;

Step 6. Heat a layer of clay on the bottom of the outer shell and then cool it into a clay pot.

Further, preferably, the temperature is 320 ° C in the step 4.

The tailless thermos bottle obtained by the invention and the preparation method thereof, the original tail pipe is not made into a pointed shape, and a gypsum fixed seal is placed at the shrinking mouth of the tail pipe, thereby solving the tail pipe too sharp and easy to be transported In the process, the problem of the insulation effect is broken, and the ceramic clay seat is installed at the bottom to improve the safety and the internal insulation effect is improved.
