The partial longitudinal cross-sectional view which shows the principal part of this invention Example. The upper exploded longitudinal section of the example of the present invention.

  The portable beverage container 1 includes a container main body 1a composed of a metal inner cylinder 2 and a metal outer cylinder 3, a bottomed cylindrical body 4 mounted on the inner side of the mouth of the container main body 1a, and an outer side of the mouth of the container main body 1a. And a lid 5 that is screwed onto the lid.

As shown in FIG. 2 and FIG. 3 or FIG. 5, the inner cylinder 2 of the container main body 1a is formed into a bottomed cylindrical shape with a metal material such as stainless steel, and the inner cylinder body 2a and the inner cylinder body 2a. The inner cylinder downward inclined portion 2b that is recessed inward with the upper end of the inner cylinder facing upward, the inner cylinder minimum diameter portion 2c extending upward from the upper end of the inner cylinder lower inclination portion 2b, and the upper end of the inner cylinder minimum diameter portion 2c An inner cylinder upper inclined portion 2d that extends slightly upward and an inner cylinder vertical portion 2e that extends upward from the tip of the inner cylinder upper inclined portion 2d are integrally formed.
As shown in FIG. 5, one inward annular protrusion 6 is provided inside the inner cylinder vertical portion 2 e of the inner cylinder 2.

  As shown in FIG. 2 or 5, the outer cylinder 3 of the container main body 1 a has a bottomed cylindrical shape so as to surround the inner cylinder 2 with a space provided by a metal material such as stainless steel that is the same material as the inner cylinder 2. The outer cylinder body 3a, the outer cylinder inclined portion 3b that is recessed inwardly with the upper end of the outer cylinder body 3a facing upward, and the outer cylinder small diameter extending upward from the upper end of the outer cylinder inclined portion 3b. The part 3c and the outer cylinder mouth joint part 3d, which is further indented from the upper end of the outer cylinder small diameter part 3c and whose tip extends upward, are integrally formed.

A male screw 7 for screwing a female screw of the lid 5 described later is engraved on the outer wall of the outer cylinder small diameter portion 3c.
As shown in FIG. 2 or FIG. 5, the outer cylinder base joint part 3d of the outer cylinder 3 of the container body 1a and the upper end part of the inner cylinder vertical part 2e of the inner cylinder 2 are overlapped and welded, and the container body 1a It is a mouth, and the gap between the outer cylinder 3 and the inner cylinder 2 is evacuated.

  As shown in FIG. 3 or FIG. 5, the bottomed cylindrical body 4 includes a protruding portion 4 a at the upper portion, a hanging portion 4 c below the protruding portion of the protruding portion 4 a, and an outer annular packing 9 at the outer peripheral wall of the hanging portion. The supporting annular protrusion 4b and the bottom plate portion 4d having a plurality of drinking mouths 10 and 10 arranged in an annular shape around the inner wall at an appropriate interval are integrally formed. Yes.

As shown in FIGS. 3 and 5, an outer annular packing 9 is fitted around the annular protrusion 4 b which is the outer peripheral wall of the hanging part 4 c of the bottomed cylindrical body 4.
The outer annular packing 9 is made of an elastic material and has an annular tongue piece 9c obliquely downward on the lower outer peripheral wall and two annular projecting tongues spaced laterally upward and downward from the upper outer peripheral wall above the annular tongue piece. The pieces 9a and 9b are integrally formed.

  In the outer annular packing 9, as shown in FIG. 4, the annular tongue piece 9c is elastically deformed into the inner cylinder upper inclined portion 2d of the inner cylinder 2 in a state where the bottomed cylinder 4 is fitted in the mouth of the container body 1a. The annular projecting tongue piece 9b below the two annular projecting tongue pieces 9a and 9b jumps over the inward annular projection 6 of the inner cylinder and elastically deforms and contacts the lower inner cylinder vertical portion 2e. The annular protruding tongue piece 9a is elastically deformed and is in contact with the upper inner cylinder vertical portion 2e of the inward annular protrusion 6.

  That is, in the outer annular packing 9 made of an elastic material, as shown in FIG. 4, the outer peripheral wall of the outer annular packing excluding the annular tongue piece 9c and the two annular protruding tongue pieces 9a, 9b and the inner peripheral wall of the inner cylinder are The annular tongue piece 9c and the two annular projecting tongue pieces 9a, 9b are elastically deformed and contact the inner cylinder upper inclined portion 2d and the inner cylinder vertical portion 2e of the inner cylinder 2 without any contact. Therefore, it is more airtight and more elastic and can be removed and installed very easily.

  Further, even if the container body is tilted, the liquid in the container body 1a is blocked by the annular tongue piece 9c of the outer annular packing 9 that is elastically deformed and brought into contact with the inner cylinder upper inclined portion 2d. Even if a droplet passes between the inner cylinder upper inclined portion 2d, contact between the lower annular protruding tongue piece 9b and the inner cylinder vertical portion 2e, and further upper annular protruding tongue piece 9a and inner cylinder vertical portion 2e Leakage can be surely prevented by the contact.

As shown in FIG. 3 or 5, the lid 5 includes a lid member 11 that covers the bottomed cylindrical body 4 that covers the mouth of the container body 1 a from above, a lid cover 12 that covers the upper end of the lid member 11, The inner cylindrical packing 13 is in close contact with the inner wall surface of the protruding portion 4a of the bottom cylinder 4 or the upper portion of the hanging portion 4c.
14 is a heat insulating material.

  As shown in FIG. 3 or FIG. 5, the lid member 11 of the lid body 5 is provided with a female screw 15 that is screwed to the male screw 7 provided on the outer cylinder 3 of the container body 1a at the lower end of the inner wall. An inner annular packing 13 is stretched around the lower portion of the inner wall of the lid member 11 and is in close contact with the protruding portion 4a of the bottomed cylindrical body 4 or the inner wall of the hanging portion 4c.

  Next, in order to directly drink the beverage in the container main body 1a, if the lid 5 is screwed off from the container main body 1a, the protruding portion 4a of the bottomed cylindrical body 4 can be put on the mouth and drink. In that case, the ice put in the container main body 1a is not disturbed by the bottom plate part 4d of the bottomed cylindrical body 4 and discharged together with the beverage.
