Description

The present invention particularly relates to a portable beverage container that can be used by children, the elderly, and the like.

Conventionally, as a portable beverage container, a gap between a metal inner cylinder (also referred to as an inner bottle) and a metal outer cylinder (also referred to as an inner bottle) is evacuated between the inner cylinder and the outer cylinder. Japanese Patent Laid-Open No. 2000-14575 discloses a portable metal thermos having a structure in which the gap between the outer cylinders is approximately 1 mm and the outer diameter of the outer cylinder is 55 mm or less.

JP 2000-14575 A

However, in a metal thermos bottle which is a portable beverage container of this type, setting the gap between the inner cylinder and the outer cylinder to about 1 mm or setting the outer diameter of the outer cylinder to 55 mm or less is simply made of metal. During the manufacturing process of the thermos, there was a problem of design that competed to make a shorter gap or a smaller outer diameter, and there was a problem of lack of concreteness without a technical basis.

In addition, children and elderly people have weak gripping force, so even if they can be gripped, the outer cylinder is circular and the surface is slippery, even if water drops etc. are attached slightly to the circular surface. There was a problem that it was inconvenient to carry.
Furthermore, in order to suppress scratches and dirt on the surface of the outer cylinder, an opaque acrylic resin paint was applied, so that there was a problem that the light transmittance was low and the overall color became dull.

The present invention includes a bottomed cylindrical metal inner cylinder 2 and an outer cylinder body 3a and an outer cylinder which are coupled at the upper end of the inner cylinder 2 with a predetermined distance from the inner cylinder body 2a and the inner cylinder bottom. In the portable beverage container 1 composed of a metal outer tube 3 having a tube bottom, the outer tube body 3a of the outer tube 3 is formed into a multi-sided shape with a polygonal cross section and this multi-sided shape. Each side 3a1 is curved inward. In addition, a highly transparent acrylic resin paint is applied to the outer surface of each side 3a1 having a multi-side shape forming the outer cylinder body 3a of the cylinder 3 after polishing.

The present invention solves the conventional problems, and by strengthening the outer cylinder, it is possible even if the gap between the inner and outer cylinders is narrow and the diameter of the container itself can be reduced. . Another object of the present invention is to provide a portable beverage container that has sufficient light diffusion, high transmittance, and deep transparency.

As shown in FIG. 2, the inner cylinder 2 of the container main body 1a is formed in a bottomed cylindrical shape using a metal material such as stainless steel, and the inner cylinder body 2a and the upper end of the inner cylinder body 2a are located upward. The inner cylinder sloping portion that is recessed inwardly toward the inside, the inner cylinder minimum diameter portion that extends upward from the upper end of the inner cylinder inclination portion, and slightly expands upward from the upper end of the inner cylinder minimum diameter portion The inner cylinder vertical part is integrally formed.

On the inner side of the inner cylinder vertical portion of the inner cylinder 2, there is provided a small annular projection that allows a projection piece of a bottomed cylindrical body 4 described later to pass downward and restricts upward movement.
The thickness of the inner cylinder 2 is about 0.3 mm.

As shown in FIG. 2, the outer cylinder 3 of the container body 1 a includes a bottom part that surrounds the bottom of the inner cylinder 2 with a space from the inner cylinder 2, and an outer cylinder body part 3 a that surrounds the inner cylinder body part 2 a of the inner cylinder 2. And an outer cylinder small-diameter portion extending upward from the upper end of the outer cylinder body portion 3a so as to surround the upper portion of the inner cylinder body portion 2a of the inner cylinder 2, and the tip of the outer cylinder is further narrowed inward from the upper end of the outer cylinder small-diameter portion. A mouth joint portion extending upward is integrally formed.
The bottom part of the outer cylinder 3 and the outer cylinder body part 3a are joined as separate members with the same material, but there is no problem even if the bottom part and the outer cylinder body part 3a are formed integrally with the same member. It's not something to do.

The outer cylinder 3 of the container main body 1a is formed so that the size of the outer cylinder 3 is about 67 mm or less so that it can be easily gripped.
As shown in FIGS. 3 and 4, the outer cylinder body 3 a of the outer cylinder 3 is formed in a multi-sided shape with a polygonal cross section. Moreover, each side 3a1 of this multi-sided shape is curved toward the center of the container body 1a as shown in FIG. The number of sides 3a1 forming the outer cylinder body 3a is best when the outer cylinder 3 has a size of about 67 mm or less, with 28 to 36, particularly 32.

The thickness of the outer cylinder 3 is the same as the thickness of the inner cylinder 2 and is about 0.3 mm. The distance closest to the inner cylinder 2 of the outer cylinder body 3a is about 3.5 mm. The farthest distance is about 3.82 mm.
As shown in FIGS. 3 and 4, since the outer cylinder body 3a has a multi-sided shape, the strength against the external pressure is greatly increased compared to the circular shape, and the thickness of the outer cylinder 3 is reduced. Even if the distance from the inner cylinder 2 can be shortened, the vacuum in the gap between the inner cylinder and the outer cylinder can be maintained, and the size of the container body 1a can be reduced to about 50 mm without changing the capacity small. It can be made as small as ˜60 mm for easy gripping.

The outer cylinder body 3a is uniformly coated with a highly transparent acrylic resin coating layer d after its outer surface is polished.
As a result, the outer surface of the outer cylinder body 3a, which has been dulled with a poor reflectance as in the prior art, has a high reflectance and is clearly visible with a sparkle and is excellent in appearance. ing.
