Embodiment 1

[0030] Figure 1~6 Example 1 is shown. Among them, the cover 3 is detachably installed on the upper opening 2 of the heat-retaining container main body 1 made of metal or resin, which is a container. The thermal insulation container main body 1 is provided with a stainless steel bottomed inner cylinder 5 on the inner side of a stainless steel bottomed outer cylinder 4, and joins the upper edges of these outer cylinders 4 and inner cylinders 5 to form a wide-mouthed upper opening 2. . Here, a vacuum layer 6 as a heat insulating layer is provided between the outer cylinder 4 and the inner cylinder 5, thereby forming a heat insulating double-layer container. In addition, a protrusion 7 is provided slightly below the upper opening 2 of the inner cylinder 5, and the protrusion 7 is formed in a segmental shape facing inward.

[0031] Here, the protrusion 7 includes: a first inclined portion 7A whose diameter decreases from above to downward; a vertical surface portion 7B extendin...

Embodiment 2

[0059] Figure 7 ~ Figure 8In order to show the second embodiment, the parts that are the same as those in the above-mentioned first embodiment are denoted by the same symbols, and the detailed description of the parts will be omitted. Regarding the packing 40 formed on the outer peripheral portion of the waterproof packing 13 of this embodiment, it is formed in the following shape. That is, the diameter cross-section extends substantially linearly from the upper portion 40A to the middle portion 40B, and the middle slope portion 40B is the largest diameter portion of the packing 40 . Furthermore, the cross-sectional diameter thereof decreases substantially linearly from the middle portion 40B to the lower portion 40C, thereby forming a lip shape in which the lower portion 40C is opened.

[0060] By forming the packing 40 in the above-mentioned configuration, the waterproof packing 13 of the inner cover 8 is pressed from above in the direction of the axis X by the air hole cl...

Embodiment 3

[0063] Figure 9 ~ Figure 10 In order to show the third embodiment, the parts that are the same as those in the above-mentioned first embodiment are denoted by the same symbols, and the detailed description of the parts is omitted. The packing 50 formed on the outer peripheral portion of the waterproof packing 13 of this embodiment is formed in the shape of a tongue protruding outward in the circumferential direction. Here, the outer diameter E of the packing portion is defined as the outer diameter of the tip portion of the packing portion 50 .

[0064] With the packing 50 having the above configuration, the waterproof packing 13 of the inner cover 8 is pressed from above in the direction of the axis X via the air hole closing packing 33 provided on the outer cover 9, and the packing 50 is elastically deformed as follows. . That is, along the first inclined portion 7A of the protrusion 7 , the filler 50 is elastically deformed in a diameter-reducing direction so as to be ro...

Abstract

The invention provides a beautiful and excellent container with a cover without former strict management of specifications and increase in clearance of the covers. The container with covers comprises an insulted container subject (1) with an upper opening (2), an internal cover (8) of waterproof fillers (13) contacting with the upper opening (2) and an external cover (9) provided with air-hole blocking fillers (33). The external cover is screwed in the insulated container subject, the unique air-hole blocking fillers positioned in the external cover are used to lock air holes (19) positioned in the internal cover and the internal cover is further pressed by the air-hole blocking fillers positioned in the external cover through pressing the internal cover. The air-hole blocking fillers are transformed and thus cannot be affected by dimension shift of parts appropriately. The external cover can be finally built to be jointed to the insulated container subject and there is no clearance between the external cover and the insulted container subject, so the container is improved in appearance and can be waterproof.

Description

technical field [0001] The invention relates to a plug body of a container with a cover. Background technique [0002] Conventionally, such a container with a cover is known as a container with a cover including a heat-resisting container having an opening, an inner cover provided with an elastic waterproof filler in contact with the opening, and an outer cover provided with an elastic member. The lower surface of the outer cover of the non-elastic member is in contact with the upper surface of the inner cover to press the container with the inner cover (for example, Patent Documents 1 and 2). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2011-230807 [0004] Patent Document 2: Japanese Patent No. 4756480 [0005] In the above-mentioned prior art, although the non-elastic component on the lower surface of the outer cover is in contact with the non-elastic component on the upper surface of the inner cover, the inner cover is fixed by pressing the inner cover, an...
