Embodiment 1

[0037] Below, according to Figure 1 to Figure 7 Example 1 will be described. figure 1 Shown is a covered container 1 of the present invention. The covered container 1 is composed of: a container body 2 having a heat-insulating double-layer structure; a lower cover 4 for covering an upper opening 3 of the container body 2 ; and an upper cover 5 attached to the lower cover 4 .

[0038] The container body 2 is composed of a bottomed cylindrical outer cylinder 6 and an inner cylinder 7 accommodated inside the outer cylinder 6 . By joining the upper ends of the outer cylinder 6 and the inner cylinder 7 , it is possible to form a heat-insulating double-layer container having a vacuum layer as a heat-insulating layer between the outer cylinder 6 and the inner cylinder 7 . Further, the inner cylinder 7 of the container body 2 is provided with a waterproof portion 8 protruding inward on the upper inner peripheral surface. In addition, a male thread 9 is provided on the upper periph...

Embodiment 2

[0056] Next, other examples will be described. Wherein, the parts that are the same as those in Embodiment 1 are denoted by the same symbols, and the detailed description of these parts will be omitted.

[0057] Figure 8 Example 2 is shown. Although in Embodiment 1, the upper portion of the inner peripheral surface of the lower cover 4 is provided with engaging protrusions 16, and the engaging protrusions 16 are provided at three positions of the inner peripheral surface at equal distances from each other, but in In the second embodiment, the engaging protrusion 16 is replaced by an engaging groove 22 . In addition, although in Embodiment 1, the outer peripheral surface of the second trunk portion 20 of the upper cover 5 is provided with an engaging groove 22, and the engaging groove 22 is provided on the outer peripheral surface in a state corresponding to the engaging protrusion 16. However, in Example 2, the engaging groove 22 is replaced by an engaging protrusion 16 . ...

Abstract

The invention provides a container with a lid, which is hygienic and has high insulation. The upper and lower covers can be integrally taken out, and the pressure-reducing state in the body can be released. The container comprises a container body (2) having an opening part, a lower cover (4) connected to the container body in a threaded manner, and an upper cover (5) embedded with the lower cover. The lower cover comprises an air hole (13) which is disposed at the center of the lower cover and is communicated with the inside and outside, and elastic filler (14) which is disposed at the lower part of the lower cover and abuts against the inner surface of the container body. The upper cover is provided with air hole sealing filler (23) having an elastic sealing part (38). One end of the inner wall of the lower cover or the outer wall of the upper cover is provided with a clamping boss (16), and the other end is provided with a clamping groove (22). The receiving and clamping boss comprises an open-state receiving part (34) keeping the upper cover in an open state, and a close-state receiving part (31) keeping the upper cover in a close state. The container with a lid can keep the upper and lower cover integrally.

Description

technical field [0001] The present invention relates to a container with a lid. Background technique [0002] Conventionally, a container disclosed by, for example, Patent Document 1 is known as the above-mentioned type of covered container. The container has: a heat-retaining container main body formed with an upper opening; an inner cover that is detachably provided to close the upper opening of the heat-retaining container main body; and an outer cover that covers the upper part of the inner cover. Screw and install on the outer peripheral surface of the heat preservation container. Wherein, the inner cover is provided with an air passage connecting the inside and the outside, and the air passage is sealed by the air hole blocking packing of the upper cover. By adopting such a structure, even when the inside of the thermal insulation container is in a depressurized state, outside air can be introduced through the air hole, and the inside of the container can be returned...
