Description

[Detailed Description of the Invention] The present invention relates to a safety device for mainly portable containers such as water bottles and, in the past, utensils.

Conventionally, when dispensing the contents inside a container, it was common to loosen or remove the stopper attached to the mouth of the container body, but this was done because it was troublesome to operate the stopper. There is provided a stopper which is provided with an on-off valve, which is operated by an operating member on the top surface of the stopper, opens the valve in the plugged trench 1, and pours out the liquid content.

However, if you forget to close the valve after use with a container equipped with the above-mentioned open/close valve stopper, and you attach the top or outer lid to the container, the container may fall over or be placed on its side while being carried. If the contents were boiling water, there was a risk of burns, etc.

The present invention was developed in view of the above circumstances, and is a safety device for containers that prevents misuse by preventing the kelp or outer lid from being attached even if the lid is attached to the container with the valve open. The purpose is to provide

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings showing embodiments thereof.

1 to 3 show a bottle according to the first embodiment of the present invention, where 1 is an exterior body, 2 is a medium bottle fixed inside the exterior body 1, and this exterior body 1 and The container body A is constituted by the medium bottle 2.

A stopper 3 equipped with an on-off valve is screwed into the mouth of the container body A.

As shown in FIG. 3, this plug 3 includes a plug cover 4, an operating member 5, a plug body 6, a valve receiver 7, a spring 8, and a seal rubber 9.
and a valve body 10.

The operating member 5 is movable in the left-right direction in FIG. 1, and has a tongue piece 5a on the left end thereof, an oblique surface 5b on the lower surface, and a recess 5c at the end of the inclined surface 5b. is formed.

The upper end of the valve body 10, which is urged upward by the spring 8, can freely come into contact with the inclined surface 5b of the operating member 5.
When the operating member 5 is moved to the left in FIG.
separates from the seal rubber 9 and opens the on-off valve (see Figure 2).
.

The upper end of the valve body 10 is fitted into the recess 5c of the operating member 5 to hold the on-off valve in an open state, and the operating member 5
The tongue piece 5a projects outward from the spout 6a.

When the container body A is tilted in this state, the liquid inside the medium bottle 2 is poured out from the lower end opening of the stopper 3 through the inside of the stopper 3 and from the spout 6a.

At this time, the tongue piece 5a has the function of guiding the flow of the liquid content and preventing drops from dripping when the container body A is stood up.

Note that the surface of the tongue piece 5a may be appropriately colored to indicate that the on-off valve is in the open state.

Reference numeral 11 denotes an outer lid, and 12 a tip. The tip 12 is placed on the shoulder of the exterior body 1 so as to cover the top surface and outer periphery of the stopper 3, and when the outer lid 11 is screwed onto the exterior body 1. The ceiling surface of the outer lid 11 presses the top surface of the top 12 to hold the top 12 so that it does not move.

When trying to attach the stopper 12 and the outer cover 11 to the outer case 1 with the on-off valve of the stopper 3 open (see Fig. 2),
The inner surface of the cup 12 comes into contact with the tongue piece 5a, and the cup 12 cannot be placed in the correct position.

Therefore, even if you try to screw the outer cover 11 onto the outer case 1,
Either they cannot be screwed together at all, or even if they are screwed together, they come off immediately.

Therefore, when the on-off valve of the stopper 3 is open, the stopper 12
and the outer cover 11 cannot be attached, and misuse can be prevented.

FIG. 4 shows a second embodiment. In the first embodiment, the lid body was composed of the top 12 and the outer lid 11, but in this embodiment, the top 12 is omitted and the upper part of the outer lid 11' is It is formed to have a small diameter so as to be close to the outlet 6a.

In this case, the tip of the tongue piece 5a hits the inner surface of the outer cover 11', and the outer cover 11' cannot be screwed onto the exterior body 1 when the on-off valve is open.

Therefore, as in the first embodiment, misuse can be prevented.

In addition to the small diameter portion of the outer lid 11/ formed all around the circumference as described above, a plurality of small diameter portions may be formed in the circumferential direction.

In both of the above embodiments, the tongue piece 5a of the operating member 5 is shown to protrude from the spout 6a, but the tongue piece 5a of the operating member 5 is not limited to this, and may protrude from any position as long as it protrudes from the circumferential surface of the stopper 3. .

The structure of the housing and on-off valve is not limited to the above, for example, the valve body 10
It may also be of the type that rotates.

As is clear from the above explanation, according to the present invention, when the on-off valve is open, a part of the lever operating member protrudes from the surface of the stopper, and this part of the operating member prevents the lid from being attached. This prevents the lid from being accidentally attached when the on-off valve is open, and there is no risk of the liquid inside spilling out, making it safe.
