Description

[Detailed Description of the Invention] This invention relates to a liquid container for containing beverages and the like.

Generally, the lower end of a liquid container is often contaminated or damaged, so it would be practically advantageous if this part could be effectively protected.

This invention provides a liquid container provided with a means for protecting the lower end, and the bottom member constituting the bottom of the container is formed to be compatible with a pot-shaped container held on the shoulder of the container. The present invention is characterized in that a protective container is provided to protect at least the bottom surface of the bottom member.

Hereinafter, this invention will be explained based on drawings showing examples.

FIG. 1 is a longitudinal sectional view of an example of a liquid container according to this invention.

In FIG. 1, this liquid container houses an inner container 3, which is a vacuum double bottle, inside an outer case 2 made of synthetic resin, metal, etc., and has a shoulder member 4 at the top and a bottom member 5 at the bottom.
, a container body 1, a stopper 6 that freely opens and closes the opening 4a provided in the shoulder member 4, and an upper cap 7, which is a pot-shaped container that also serves as a lid, and the bottom. It is equipped with a protective container 8.

The outer case 2 has a non-tapered cylindrical body, and its upper and lower ends are narrowed to have a small outer diameter, and screws are provided on the outer periphery of these parts.

A shoulder member 4 having a rib 4d is screwed onto the screw 2a at the upper end of the outer case 2 via a ring-shaped packing 9 so as to press the inner container 3.

The plug body 6 containing the heat insulating material 6d is removably attached to the shoulder member 4 by screwing the opening screw 4b of the shoulder member 4 with a screw 6a provided on its protruding portion.

In this case, when the cap is closed, the convexly curved flange 6b of the cap 6 comes into close contact with the inner surface of the trumpet opening 4c of the shoulder member 4, thereby preventing the liquid in the inner container 3 from flowing out.

Furthermore, when the cap is closed, the lower part 6c of the cap 6 fits into the opening of the inner container 3, improving the heat retention effect in that part. It may also be press-fitted into the opening 4a of the member 4.

A bottom member 5 is screwed onto the screw 2b at the lower end of the outer case 2.

The bottom member 5 is formed as a cylindrical body having a threaded portion 5a at the upper end thereof, and a cylindrical cavity portion 5b is provided in the center thereof.

The threaded portion 5a has an outer diameter approximately equal to the outer diameter of the outer case 2, and a screw provided on the inner surface of the threaded portion 5a screws into a screw 2b at the lower end of the outer case.

The outer diameter of the lower part of the threaded part 5a is slightly reduced to form a body part 5c, and a plurality of reinforcing ribs 5d are provided from the inner surface of the body part 5c to the peripheral wall of the hollow part 5b.

In addition, the outer peripheral part of the bottom of the bottom member protrudes to form a lower edge 5e.
, and when the protective container 8 is removed, only this lower edge 5e is in contact with the table surface.A trumpet-shaped catch 10 is attached to a screw provided on the inner surface of the hollow part 5b of the bottom member 5.
The holder 10 having a holder 10a is screwed onto the holder 10. The holder 10 supports the lower end of the medium container 3, and the medium container 3 is placed on the receiving seat 10a.

That is, the inner container 3, which is a vacuum double bottle, is held in a pinched state between the shoulder member 4 and the receiver 10.
A protruding strip 10b is formed on the receiving seat 10a of the container 0, and the upper cap 7, which is a lid that also serves as a lid, is removably screwed onto the shoulder member 4 of the container 0, which is in contact with the bottom of the inner container. However, the upper cap 7 prevents the opening from becoming dirty and can also be used as a stopper, and is not limited to the screw-fitting method, but can also be fitted using the so-called force-fitting method, which uses the elasticity of the material, for example. It may also be made to cover the container body.

Further, a string attachment piece 11 is provided on the socket portion 4e of the shoulder member 4, and a hanging string 13 is attached to this via a hanging ring 12. In the illustrated example, the string attachment piece 11 is provided integrally with the shoulder member 4. However, it may be manufactured separately and attached by screws or the like, or it may be provided at other positions such as the outer case 2.

The protective container 8 is screwed onto a screw provided on the outer periphery of the body 5C of the bottom member 5 so as to cover the bottom member 5.

The protective container 8 is made of various materials such as synthetic resin, metal, or an elastic material such as rubber, and is used to protect the lower end of the container body 1, with a gap between it and the lower end surface of the bottom member 5. Although it is screwed on with 8a maintained, the installation method is not necessarily limited to the screwing method, but it can be installed using other methods such as force-fitting or screwing, as in the case of the upper cap. Good too.

Like the upper cap, the protective container 8 is also formed in a shape that can be used as a pot, so it is convenient when used by a large number of people.

Further, since the upper cap 7 and the protective container 8 are formed to be compatible, it is convenient because there is no need to identify and confirm the two when reattaching them to the device body after using them.

In particular, if both are made to have the same shape and dimensions, it is economical because there are fewer types of parts.If the medium container is a vacuum double bottle like the example shown, it is vulnerable to vertical impact. Therefore, it is particularly effective to provide such a protective container 8.

FIG. 2 shows a screw 5f attached to the lower outer periphery of the cavity 5b of the bottom member 5.
An example in which the protective container 8 is attached to the bottom member 5 by providing a cylindrical screw socket 8b at the bottom of the protective container 8 and screwing the screw socket 8b into the screw 5f of the bottom member. 3 shows an example in which a rubber cushioning material 14 is provided at the lower end of the protective container 8.

The buffer material 14 is force-fitted into the protective container.

In this example, an annular rim 8c is provided at the lower end of the protective container 8, and a groove 8d is formed on the outer periphery of the base of the rim 8c.

The cushioning material 14 also has a protrusion 14a on the peripheral edge of its lower end surface.
is formed, and a groove 14b is provided on the back side of the protrusion 14a.

A projecting piece 14c having a hook-shaped cross section is provided at the upper edge of the groove 14b.

The buffer material 14 is attached to the protective container 8 by fitting the rim 8C into the groove 14b. In this case, the overhang piece 1
4c fits into the concave groove 8d of the rim, ensuring the retention of the cushioning material. If the cushioning material 14 made of such an elastic material is provided, the protective effect will be further improved, and the lower end will not close when being carried. It is preferable to make the cushioning material 14 itself removable so that it can relieve pain even if the child hits the child's head.If the cushioning material 14 itself becomes removable, it is convenient because only this material can be removed and washed if it gets dirty. Figure 4 shows a gap 8a formed between the lower end of the bottom member 5 and the bottom surface of the protective container 8.
Here is an example in which a cushion 15 made of an elastic material such as foamed resin is inserted.

Adding such cushioning will further improve impact resistance.

The liquid container according to the present invention has a protective container that protects at least the bottom of the bottom member attached to the bottom member that constitutes the bottom of the container housing the inner container. This makes it possible to effectively protect the bottom of the vessel from shocks caused by accidental contact or falls.

This protective container can be used as a pot, and is compatible with the pot-shaped container held on the shoulder of the device, so no extra care is required when putting it on after use. It has become extremely convenient in practice.
