Description

[Detailed description of the invention] The present invention relates to a liquid container such as a thermos or electric pond, and more specifically, a flap that opens and closes the spout (spout opening/closing lid).
This invention relates to a liquid container provided with a.

In this type of liquid container with a flap, there may be a gap between the back of the flap and the end of the spout when the flap is closed, and dust and small insects may enter the liquid injection path through this gap. was there.

In particular, in liquid containers of the type in which the liquid injection passage provided in the stopper is opened and closed by the vertical movement of the valve body (so-called one-button stopper type), the flap can be opened and closed in conjunction with the opening and closing operation of the valve body. Due to manufacturing dimensional errors of the flap opening/closing mechanism interposed between the valve body opening/closing mechanism and the flap, or errors in its mounting position, a gap is likely to be formed between the valve body opening/closing mechanism and the flap, resulting in a gap between the flap and the spout. A gap is likely to be formed between the end face of the part and the end face of the part.

In view of the above-mentioned problems, the present invention proposes that even if the liquid container is equipped with a flap opening/closing mechanism in which the flap can be opened/closed in conjunction with the valve body opening/closing mechanism, the flap and the spout will be removed when the flap is closed. The gap between the end face of the part and the end face of the part can be made as small as possible, thereby preventing dust and small insects from entering into the liquid injection passage.
The object of the present invention is to provide a liquid container that allows a relatively simple structure to reduce the gap between the lamp and the end face of the spout, and which includes a flap drive mechanism. It is guided by the upper surface of the partition plate arranged to divide the interior of the liquid groove into upper and lower parts, and is slidable back and forth. Furthermore, when the 7 lamps are closed, the 7 lamps are moved in the lid closing direction between the valve body opening/closing mechanism and the flap. This feature is characterized by the interposition of a buffer member that acts to bias the body.

The guide cylinder 23 can be stopped at two positions (valve position).

The inner circumferential surface of the guide tube 23 is provided with a deep groove 24 and an intermediate protrusion 2 in order in the circumferential direction from the upper end thereof until a predetermined depth is reached.
5. Shallow grooves 26 are formed at equal intervals.

The deep grooves 24 and the shallow grooves 26 are formed at 6 locations each, and the intermediate protrusions 25 are formed at 12 locations.

The bottom surface of the deep groove 24 is a stepless continuous surface with the inner surface of the lower portion of the guide cylinder 23, and the lower portion of the deep groove 24 is completely open.

At the lower ends of the intermediate protrusion 25 and the shallow groove 26, inclined surfaces 25a and 26a are formed which are continuous and inclined in the same direction.

The crown button 21 has an inner and outer double wall structure, with the inner wall 27 extending downward longer than the outer wall 28.

An outward facing flange 28a is formed at the lower end of the outer wall 28, and by engaging the flange 28a from below with a step 19a formed on the inner surface of the guide tube 19 at the top of the stopper unit main body 11, the crown button 21 The plug unit is prevented from being pulled out upward from the guide tube 19 of the main body.

Engagement protrusions 29, 29, etc., which are vertically movably fitted into the deep grooves 24 and shallow grooves 26 of the guide tube 23, are formed at equal intervals on the lower end of the outer peripheral surface of the inner wall 27 of the coronal button. The locking protrusions 29, 29... are formed into deep grooves 24, respectively.
．． 24... and shallow grooves 26, 26..., the crown button 21 can be slid only in the vertical direction with respect to the guide tube 23.

Further, on the lower end surface of the inner wall 27 of the coronal button, the center of the engaging protrusion 29 is formed into a "mountain", and two engaging protrusions 29 adjacent to each other are formed.
．． Saw-toothed irregularities 29a are formed in which the intermediate position between 29 is a "valley".

The rotating body 22 is provided with protrusions 30, 30, .

These protrusions 30, 30... are the deep grooves 24 of the guide tube 23.
(or shallow groove 26) and the same number and spacing (60° intervals at C locations)
The upper surface of each of the protrusions 30, 30... is an inclined surface inclined in the same direction as the inclined surfaces 25a and 26a formed at the lower ends of the intermediate protrusion 25 and the shallow groove 26 of the guide tube 23. 30a is formed.

The protrusion 30 fits into the guide tube deep groove 24 so as to be able to move up and down, but cannot fit into the guide tube shallow groove 26, so that it cannot fit into the guide tube shallow groove 26.
6, the rotating body 22 is prevented from moving upward.

This rotating body 22 is urged upward within the guide cylinder 23 by a push-up spring 31 interposed between the lower surface of the rotating body 22 and the stopper unit main body partition 160.

The upper end of the valve rod 115 is fixed to the center of the lower surface of the rotating body 22 by a screw 32, and as the rotating body 22 moves up and down, the valve body 13 moves up and down with respect to the plug unit body 11. It is supposed to be done.

When the valve body opening/closing mechanism A is operated, the flap 9 is opened/closed by a flap opening/closing mechanism B in conjunction with the operation. 34 and the cam 3
Slide pin 3 that is moved forward and backward by 4.
5, and a slider 37 interposed between the slide pin 35 and the rear end 9C of the flap 9 via an intermediate member 36.

The cam 34 formed on the outer surface of the inner wall 27 of the crown button protrudes forward (toward the flap attachment side), and in the upward movement position of the crown button 21 (FIG. 1), the cam crest pushes the slide pin 35 forward. , the pressed position of the crown button 21 (
In FIG. 5), the cam crest is located below the slide pin 35 so that the slide pin 35 can be moved backward.

The slide pin 35 penetrates the side wall of the plug unit main body 11 and is slidable only in the front-back direction.

The slider 37 is housed in a cavity 43 formed above a partition plate 41 provided in the liquid guide section 8 so as to be guided by the upper surface of the partition plate 41 and slidable in the front-rear direction.

An intermediate member 36 is interposed between the slider 37 and the slide pin 35, so that the pressing force from the slide pin 35 is transmitted to the slider 37 via the intermediate member 36.

Note that the intermediate member 36 is slidable in the front and rear directions relative to the slider 37.

The front surface of the slider 37 is in contact with the upper rear end of the 72 amplifier 9, and when the slide pin 35 abuts against the cam ridge of the cam 34, the front surface of the slider 37 resists the spring 44 and the flap 9 is pressed in the direction of closing the lid.

A concave chamber 38 is formed on the back side of the slider 37,
A buffer member 40 such as rubber or sponge having an appropriate elastic force is accommodated in the recessed chamber 38 .

The protrusion 36a formed on the front side of the intermediate member 36 is loosely fitted into the recess 38 on the back side of the slider 37, so that the front surface of the intermediate member front protrusion 36a comes into contact with the buffer member 40.

This buffer member 40 functions to absorb the clearance between the rear end 9c of the flap 9 and the cam ridge of the cam 34 when the flap is closed, thereby urging the 72 cam 9 in the direction of closing the lid. The buffer member 40 is arranged so as to be slightly compressed between the intermediate member 36 and the slider 370 when the flap is closed (when the crown button 21 is moved upward).

The elastic force of the buffer member 40 when the flap is closed is set to be greater than the elastic force of the spring 44 for opening the 72 knob, so that the back surface of the flap 9 is at the tip of the liquid guide section 8 when the flap is closed. It is adapted to be pressed against the opening edges of the opening 8a and the upper opening 8b.

In the figure, reference numeral 18 is a concave portion formed in the center of the partition wall 16 of the plug unit main body 11, and 33 is an annular packing attached to the outer periphery of the valve stem 15. As shown in FIG.
It is press-fitted into the recessed portion 18 and acts to seal the inside of the recessed portion 18 .

Therefore, during liquid injection, the liquid W flows into the upper chamber 17 above the partition wall 16.
It is designed to reliably prevent water from entering the interior.

Further, reference numeral 39 indicates a heat insulating material filled in the valve portion 14.

Next, we will explain how to use and function the liquid container of the first embodiment of the present invention shown in Figs. 1 to 5. When not injecting liquid, the crown button 21 is stopped at the upward movement position as shown in Fig. 1. If the valve body 13 is
The valve 2 is biased upward to close the valve, and in this state, the inside of the liquid container 3 is completely sealed.

In the state shown in FIG. 1, each member of the valve body opening/closing mechanism A is engaged as shown in FIG. 4A.

When dispensing liquid, the crown button 21 is pressed to open the valve body 13 and the flap 9 is opened.

That is, when the crown button 21 is pressed down, the engaging protrusion 29 pushes down the rotating body protrusion 30 as shown in FIG. Due to the engagement protrusion 29 and the lower end of the protrusion 30 contacting each other in an inclined manner, the protrusion 30 (rotating body 22) moves laterally in the direction of arrow X.

Then, when you release your hand from the crown button 21, the spring 31
The rotating body 22 tries to move upward due to the restoring force, but the upper surface (slanted surface 30a) of the protrusion 30 contacts the lower ends of the intermediate protrusion 25 and the shallow groove 26 in an inclined manner, and the protrusion 30 further moves upward. The rotating body 2 moves laterally in the direction of arrow
2 is stopped.

Therefore, in this state, the valve body 13 is maintained in the open state as shown in FIG.

On the other hand, when the crown button 21 is pushed down as described above, the cam 34 formed on the crown button 21 also moves down, allowing the slide pin 35 to retreat, and the pressing force on the flap 9 in the closing direction is released, and the spring 34 is released. The action causes the flap 9 to open (FIG. 5).

Note that when the flap 9 is opened, the upper part of the rear end 9c moves rearward, causing the slider 37, intermediate member 36, and slide pin 35 to move rearward.

Further, when closing the valve and flap after dispensing the liquid, when the crown button 21 is pressed down again, the protrusion 30 is moved downward by the engagement protrusion 29 as shown in the fourth figure.
The protrusion 30 moves laterally in the direction of the arrow Y along the lower end inclined surface 25a of the intermediate protrusion 25, and then when the crown button 21 is released, the protrusion 30 further slides laterally in the direction of the arrow Y and reaches the fourth position.
As shown in FIG. E, the valve overlaps the deep groove 24 and moves upward in the deep groove 24, returning to the state shown in FIG. 4A, that is, the closed state shown in FIG. 1.

At the same time, when the crown button 21 moves upward, the slide pin 35 is pushed forward by the cam 34, and the rear end 9c of the flap 9 is pushed forward via the intermediate member 36 and the slider 37, thereby closing the flap 9. It works like this.

When the seventh lamp 9 is closed, the buffer member 40 provided on the slider 37 is compressed.
A repulsive action occurs in the flap 7 and acts to urge the lamp 9 in the direction of closing the lid, and the back surface of the flap 9 closes the tip spout 8a and the upper opening 8b of the liquid guide part 8 in a substantially tight state. .

6 to 11 show modified examples of the mounting structure of the buffer member 40 according to the second to seventh embodiments of the present invention, respectively.

In the case of the second embodiment shown in FIG. 6, the buffer member 40 attached to the slider 37 is extended rearward until it reaches the front end of the slide pin 35, and the intermediate member 40 in the first embodiment
6 is omitted.

In the case of the third embodiment shown in FIG. 7, the buffer member 40 is attached to the front surface of the slider 37 so as to protrude toward the front side, and the front end of the buffer member 40 is brought into contact with the rear end 9C of the flap 9. I have to.

In the case of the fourth embodiment shown in FIG. 8, the buffer member 40 has an upper part 40a having a length reaching from the front end of the slide pin 35 to the rear end 9c of the flap 9, and a lower part 40a thereof.
b is held by a slider 37.

In the case of the fifth embodiment shown in FIG. 9, the buffer member 40 is attached to the rear end 9c of the flap 9.

In the case of the sixth embodiment shown in FIG. 10, a plate spring is used instead of rubber or sponge as the buffer member 40, and the plate spring 40 is attached to the rear side of the slider 37.

In the case of the seventh embodiment shown in FIG. 11, a resin spring is adopted as the buffer member 40, and the resin spring 40 is
It is integrally formed on the front side of 7.

Next, to explain the effects of the present invention, the liquid container of the present invention opens and closes the flap 9 that covers the spout 8a of the liquid guide portion 8 in conjunction with the opening and closing operation of the valve body 13 attached to the stopper unit 10. In the liquid container thus obtained, a buffer member 40 is interposed between the valve body opening/closing mechanism A and the flap 9, which acts to bias the flap 9 in the closing direction when the flap is closed. When the flap is closed, the flap 9 comes into close contact with the spout 8a, and the gap between the flap 9 and the spout 8a is almost eliminated, preventing dust and small insects from entering there. There is an effect.

In addition, in the liquid container of the present invention, the flap opening/closing mechanism B is slidable back and forth using the upper surface of the partition plate 41 disposed in the liquid guide section 8 as a guide, so that the flap opening/closing mechanism B The flap opening/closing mechanism B can also be used as a guide member for sliding back and forth, and the mounting structure of the flap opening/closing mechanism B can be simplified.
