Description

Insulation bowl

Technical field

The invention relates to the technical field of heat-insulating tableware, in particular to the technical field of a heat-insulating bowl, and more particularly to a heat-insulating bowl for children.

Background technique

Tableware is a necessity in people's daily life. With the improvement of material living standards, the requirements for tableware are also higher. For example, it is necessary to have a certain insulation effect, especially for children who eat at a slower rate. Insulation is very important for children's tableware.

Items commonly used for insulation in the prior art include: thermos cups, thermos bottles; but such insulation items are usually filled with a material that is insulated between the two compartments, and then poured into the inner layer. In this way, the hot water is kept warm; but the shapes and bowls of the cups and the thermos are quite different, and the objects of the heat preservation are different, so the known cups and thermos cannot be used as a heat preservation bowl.

For example, in the patent application of the Chinese Utility Model Application No. CN94206858.0, a thermal insulation bowl is disclosed in order to solve the technical problem that the food in the bowl is cooled quickly, and a bowl is placed outside the bowl and attached to the bowl. The insulation layer and the inlet and outlet ports are composed.

In the process of realizing the present invention, the inventors have found that although the above patent gives a solution for the heat preservation of the tableware of the bowl, when the hot water is injected into the interlayer between the bowl and the bowl, the bowl is easy to heat the water. The heat is transmitted to the outside, so the heat preservation effect is poor; and when the heat preservation bowl is initially injected with hot water, when the temperature is high, it is easy to burn to the hand.

Summary of the invention

In order to solve the technical problem that the heat preservation bowl in the prior art has inconvenient to heat the set bowl, the invention provides a heat preservation bowl, which is convenient to operate in the liquid removal process, and has convenient liquid discharge, and can completely discharge the heat preservation medium.

In order to achieve the above object, the technical solution provided by the present invention includes:

The invention provides a heat preservation bowl, comprising: a food receiving portion for containing food; a heat insulating medium receiving portion, which is provided with a hollow receiving cavity for containing the heat insulating medium; and the method further comprises:

a first engaging portion located outside the food receiving portion;

a second engaging portion located inside the heat insulating medium receiving portion, the second engaging portion being disposed to cooperate with the first engaging portion such that the food receiving portion is mounted to the heat insulating medium receiving portion, in both Forming a closed area between the insulating medium; and

a hollow partition located in an outer wall of the heat insulating medium housing.

Preferably, the heat insulating medium accommodation portion includes a first component opposite to the food receiving portion and a second component detachably connected with respect to the first component, and the second component card After the first component is connected, the hollow partition is formed.

Further preferably, in the embodiment of the present invention, the inside of the hollow partition is further provided with a reinforcing rib.

In an embodiment of the invention, preferably, the first engaging portion and the second engaging portion are respectively meshing threads.

Preferably, the heat preservation bowl further comprises: a first sealing element located between the heat medium receiving portion bowl and the food receiving portion.

Preferably, the heat preservation bowl further includes: a vent hole disposed in the heat insulating medium accommodating portion and communicating with the sealed area accommodating the heat insulating medium.

Further preferably, the venting hole is disposed in a sidewall different from the hollow partition portion; and is located at the position of the heat insulating medium accommodating portion and located at the side wall of the sealing portion.

According to still further preferred embodiments of the present invention, the heat insulating bowl further includes: a handle located outside the side wall, the vent hole extending from an inner side of the side wall to the handle.

Further preferably, the heat preservation bowl further includes: a handle disposed outside the side wall, the hollow partition is U-shaped, and a top end of the hollow partition extends to the handle Location.

In an embodiment of the invention, preferably, the venting hole is located below the second engaging portion at the position of the side wall, and is adjacent to the second engaging portion.

Preferably, the heat preservation bowl further includes: a limit line located inside the heat insulating medium receiving portion.

Preferably, the heat insulating bowl further includes: a connecting portion detachably connecting the food receiving portion and the heat insulating medium receiving portion, and the connecting portion is provided with a side corresponding to the heat insulating medium receiving portion The wall is connected by a thread; the side wall of the food receiving portion is provided with a protrusion extending toward the connecting portion, and the connecting portion is provided with a retaining portion extending toward the food receiving portion.

Further preferably, in the embodiment of the present invention, the connecting portion further includes a grip portion.

With the above technical solution, at least one of the following beneficial effects can be obtained:

1. Since the hollow insulation portion is disposed in the outer wall of the heat storage medium accommodating portion, the hollow insulation portion does not dissipate heat, so the heat dissipation of the heat preservation medium is unidirectional, that is, heat is only radiated to the food side, so that the food insulation effect in the food accommodating portion is more .

2. The venting hole is arranged in the heat preservation bowl. When the temperature of the heat insulating medium in the heat insulating bowl is lowered, even if the pressure of the sealing area of the heat insulating medium changes, the atmospheric pressure difference between the sealed area of the heat insulating medium and the outside is reduced through the vent hole. This reduces the food receiving portion from being sucked on the heat insulating medium housing portion.

3. A sealing ring is further disposed between the heat insulating medium receiving portion and the food receiving portion, which can further increase the sealing performance of the heat insulating medium between the heat insulating medium receiving portion and the food receiving portion, and enhance the heat insulating effect.

Other features and advantages of the invention will be set forth in part in the description which follows. The objectives and other advantages of the invention may be realized and obtained by the structure and/or <RTIgt;
