Description

[Detailed description of the invention] (a) Field of the invention This invention is a portable device that can be used for both solid and liquid purposes to keep the solid or liquid contents stored in a heat-insulating inner container warm or cold for a long time. Regarding thermal insulation containers.

(b) Prior art If the insulating container has a small diameter injection port,
Air convection inside and outside the inner container is reduced in proportion to its diameter, improving heat retention performance.

However, if the diameter of the injection port is small, it becomes difficult to inject the liquid and clean the inside of the inner container.

For this reason, conventionally, the injection port of this type of portable heat-retaining container has been formed to an appropriate diameter that allows cleaning of the inner container and that reduces the deterioration of heat-retaining performance.
Therefore, the upper end of the inner container needed to be wider and narrower than the inner container in accordance with the diameter of the injection port, but this structure had the following problems. .

(1) Solid objects larger than the diameter of the injection port, such as fruits, canned goods, lunch boxes, etc., cannot be stored, and the device is limited to liquid use only.

(2) Because the diameter of the injection port is narrow, the inner container cannot be easily cleaned, and the shoulder near the injection port is very difficult to clean, which is not sanitary.

(3) In order to narrow the diameter of the injection port, it is necessary to fit and fix an upper member made of a separate material to the upper end of the inner container. The work of fitting and fixing is required, which increases assembly cost and lowers productivity.

(4) Because the liquid-only lid and handle protrude from the top of the main case, it is impossible to stack the products, and the packaging becomes bulky, increasing shipping costs.

(c) Purpose of the invention Therefore, this invention was developed by making the upper end opening of the inner container approximately the same size as the inner diameter of the inner container, and providing a lid body with a liquid inlet thereto to create a portable container that can be used for both solid and liquid applications. The purpose is to provide thermal containers.

(d) Structure of the invention In the portable heat-insulating container of this invention, a removable lid body is provided in the opening hole of the shoulder member that can be sealed or completely opened. A liquid inlet having a recessed step is formed in the recessed step, and a liquid exclusive lid is provided on the liquid inlet, which is screwed from the outer periphery, leaving a gap in which the recessed step can be attached and detached. When the dedicated lid is in a sealed state, its upper surface is provided at the same height or lower position as the upper surface of the lid, and a handle storage step is provided on the back side of the lid.

(e) Effects of the invention The portable heat-insulating container of this invention has many practical effects as follows.

(1) One unit can be used for keeping liquids or solids warm or cold depending on the purpose of use, making it more practical.

(2) Since the upper opening of the inner container can be completely opened, cleaning of the inner container is easy and hygienic as every corner can be thoroughly cleaned.

(3) Even when the passage of the liquid dispensing tool becomes clogged with foreign matter such as tea leaves, the foreign matter can be easily removed from inside the inner container, improving serviceability.

(4) There is no need for a separate upper member to form a narrow liquid inlet, reducing component costs and eliminating the need for fitting and fixing the upper member to the upper end of the inner container. The assembly process is simplified and assembly costs are reduced.

(5) Since the liquid-only lid is provided while leaving a gap necessary for attaching and detaching the liquid-only lid in the recessed step, the liquid-only lid can be attached and detached by inserting your fingertip into the above-mentioned gap and rotating it. It is easy to operate.

(6) Since the lid for liquids and the handle do not protrude from the upper surface of the lid that constitutes the main case, products can be stacked, and packaging is also less bulky, reducing inventory transportation costs.

(f) Example of the invention An example of the invention will be described below in detail based on the drawings.

The above-mentioned bottom member 4 communicates with the lower end of the above-mentioned inner container 6 at the lower front thereof, and is provided with a liquid spouting tool 10 that can be opened and closed for pouring out the content liquid injected into the inner container 6 to the outside. ing. Further, folding legs 11 are pivotally mounted at diagonally equal intervals on the lower end surface, and when in use, the legs are opened downward to create an insertion space for inserting a tip or the like between the installation surface and the liquid dispensing device 10 mentioned above. When stored, it is folded upward as shown by the two-dot chain line to reduce the storage size.

In the shoulder member 3, the flange portion 13 provided inwardly of the outer case 2 is forcefully fitted into the fitting groove 12 provided on the lower end surface of the outer periphery of the shoulder member 3, so that the shoulder member 3 is irremovably fixed. ing. Further, an opening hole 14 communicating with the inner container 6 described above is formed on the inner surface of the upper end, and a seal protrusion 15 that surrounds this opening hole 14 and projects upward is provided around the lid body 1.
When the inner container 6 is covered from above, it engages with the seal packing 17 provided opposite to the lid 16 and closes the inner container 6.
