Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a cylindrical portable liquid container.

<Prior art> Conventionally, cylindrical portable liquid containers have consisted of glass single-layer bottles or vacuum double-layer bottles surrounded by a metal exterior case, and stainless steel vacuum double-layer bottles surrounded by an outer wall of the outer bottle. However, since this type of portable liquid container has a cylindrical shape and an outer wall made of metal, it is difficult to grasp the outer wall when pouring the liquid inside the bottle. Also, it was a challenge to make sure to pour everything into the pot.

Furthermore, if the container is accidentally dropped, the outer wall will become dented, making the appearance unsightly, and in the case of stainless steel vacuum double-sided bottles, the dents will significantly reduce the heat retention effect.

<Purpose of the invention> The present invention has been made in view of the above points, and provides a portable liquid container that is comfortable to hold when dispensing liquid, is resistant to drop shocks during long-term use, and has excellent heat retention effect. There is something to do.

<Structure of the invention> According to the invention, large annular protrusions are provided at the top and bottom of the cylindrical body of the container body of the stainless steel vacuum double bottle, and surface irregularities are formed between the large annular protrusions at the top and bottom. The objective is to be achieved only with a structure in which a cylindrical body made of an elastic material is stretched.

<Embodiments of the invention> Examples of the invention will be described below with reference to the drawings.
The portable liquid container 1 includes a container body 2, an inner stopper 3 that is detachably attached to the inner periphery of the mouth of the container body 2, and a cap 4 that surrounds the inner stopper and is detachably attached to the lower end of the outer periphery of the mouth of the container body 2. It is composed of a cylindrical body 5 stretched over the central outer wall of the body of the container body 2.

The container body 2 is a vacuum double bottle with vacuum insulation between the inner bottle 6 and the outer bottle 7 made of stainless steel, and a screw for an inner stopper is carved into the inner periphery of the mouth of the inner bottle, and a screw for an inner stopper is carved into the lower end of the outer periphery of the mouth of the outer bottle. A screw for the tip is engraved. As shown in FIG. 1, the outer wall of the container body 2 is provided with an upper annular large protrusion 8 and a lower annular large protrusion 9 above and below, apart from the center of the body. An upper annular small protrusion 10 and a lower annular small protrusion 11 are provided below the lower annular large protrusion 9, respectively. A ring body 12 equipped with a locking part (not shown) for a hanging string is attached to this upper annular protrusion, and a ring body 12 that covers the bottom of the container body 2 is attached to the lower annular protrusion 11. Bottom plate 1 fitted to the protrusion
3 is installed. The maximum diameter of the bottom plate 13, which is the portion that fits into the lower annular small projection 11, is slightly smaller than or equal to the outer diameter of the lower annular large projection 9. This bottom plate 13 protects the bottom of the container body 2 from impact from falling.

The cap 4 is formed into a cylindrical shape with a bottom, has a screw carved into the inner periphery of the upper end, and is removably screwed into the cap screw at the lower end of the outer periphery of the mouth of the container body 2 in an inverted position. This tip, together with the ring body 12 described above, protects the upper part of the container body from falling impact.

The cylinder 5 is made of an elastic material such as rubber and has a hollow cylindrical shape, and as shown in FIGS. 1 and 3, its inner diameter is slightly smaller than the outer diameter of the container body 2, or are equal. The outer surface of the cylindrical body 5 is provided with a plurality of recesses 14 and protrusions 15 for preventing slipping, as shown in FIGS. 1 to 4. This cylinder 5
is inserted from the bottom of the container body 2 while its inner diameter is expanded by elastic force, and passes over the bottom plate 13 covering the lower annular small projection 11 and the lower annular large projection 9 to form the upper annular large projection 8 and the lower annular large projection 8. It is set up between 9 rooms.

<Effects of the invention> In the present invention, annular projections are provided at the upper and lower parts of the body of the outer metal container body, and a cylinder made of an elastic material with an uneven surface is stretched between the two projections. In addition, the large annular protrusion at the bottom prevents the cylinder from slipping out of the body of the container when liquid is poured out, and since the cylinder is made of elastic material, the inner diameter of the cylinder expands. It is easy to install and can be easily attached to the body of the container.

In addition, the cushioning properties of this cylindrical body do not leave any dents in the body of the container body even when the liquid container is dropped, which often occurs when carrying it outdoors, so the heat retention effect is maintained sufficiently even during long-term use. I can do it.

Furthermore, due to the elastic material and surface irregularities, when pouring liquid inside the container body, it is comfortable to hold if you hold the surface of the cylindrical body while pouring, and even if you hold the barrel of the container body with your hand and pour it, it will not slip. In particular, even if the liquid in the container body is repeatedly poured into the tip and the liquid adheres to the container body, the pouring can be performed reliably without slipping.
