Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to liquid containers such as thermos flasks, and more specifically, to enable liquid to be poured into the container body with the stopper attached to the stopper hole in the closed state. The present invention also relates to a liquid container in which a covering member that can be used as a lid or a liquid receiving container is attached to the top of the container body.

(Prior art) As this type of liquid container, the one shown in Fig.
Publication No. 178929). In this known liquid container, a plug body 102 is installed in a plug hole 121 of a container body 101, and a plug body 102 is provided with a liquid injection passage 127 and a valve body 141 for opening and closing the liquid injection passage 127 in a plug body 125. The upper part of 101 is removably covered with a covering member 103 which serves as a lid or a liquid receiving container. Stopper body 1
The liquid injection passage 127 in 25 has a liquid inlet 127a on the lower surface of the stopper body, and a liquid injection port 1 on the upper outer surface of the stopper body.
27b, respectively. When dispensing liquid from this known liquid container, remove the covering member 103, press down the valve operation button 145 once with the stopper 102 attached to open the valve, and in this state, open the entire liquid container. By tilting the liquid in the container main body 101, the liquid in the stopper liquid injection passage 1
27 and can be poured out from the liquid injection port 127b.

(Problem to be solved by the invention) By the way, in the known liquid container shown in FIG.
Since the liquid injection port 127b of the liquid injection passage 127 in the stopper is always open on the outer surface of the upper part of the stopper body, if the covering member 103 is left unattended, water will enter the liquid injection passage 127 from the liquid injection port 127b. There was a risk of dust and small insects getting in, and there was room for improvement in terms of hygiene.

In view of the above-mentioned problems of known liquid containers, the present invention provides a liquid container in which the liquid injection passage inside the stopper can be opened and closed by operating the valve while the stopper is in a closed state. A flap is provided to open and close the liquid injection port of the liquid injection passage to prevent dust and small insects from entering the liquid injection passage even when the covering member is removed. The purpose of this design is to make it easy to open and close the valve, and to ensure that the valve remains closed even if you forget to close the valve body by attaching a covering member.

(Means for Solving the Problems) The present invention provides a stopper that includes a liquid injection passage and a valve body for opening and closing the liquid injection passage in the stopper body, and a lid or a liquid receiving container that covers the outside of the stopper. In a liquid container equipped with a covering member such as the above, the liquid container is pivotally connected to the stopper body so as to be rotatable in an arc, and opens and closes the liquid inlet of the liquid injection passage, and when the liquid inlet is in an open position. A flap projecting upward from the upper surface of the stopper body and a knob member that can be operated from above the stopper body and can be moved horizontally within the stopper body are provided, and the upper end surface of the knob member is placed in the inlet opening position. The knob member is provided so as to be located below the uppermost end position of the flap, and further, a valve body operating part for opening and closing the valve body and a flap operating part for opening and closing the flap are integrally molded on the knob member, In addition, the flap is configured such that when the flap is in the spout open position, it is pushed down by the cover of the covering member to operate the valve body operating portion and position the valve body in the valve closed position. It is characterized by

(Function) According to the liquid container of the present invention, the flap can close off the liquid injection port of the liquid injection passage in the stopper, so even when the covering member is removed, dust does not enter the liquid injection passage inside the stopper. It can prevent the invasion of insects such as insects and small insects. Furthermore, by opening and closing a single knob member, the valve body for opening and closing the liquid injection passage and the flap for opening and closing the liquid injection port can be simultaneously opened and closed. Furthermore, if the covering member is attached even if the valve member has forgotten to close the valve member, the covering member will push down the open flap and automatically close the valve member. In addition, since the knob member is provided so that it can be moved horizontally inside the stopper body separately from the flap, even if an external object collides with the knob member, the flap will not be accidentally opened. can be prevented.

(Effect of idea) The liquid container of the present invention has the following effects.

(a) Even if a liquid injection passage is provided inside the stopper body so that liquid can be poured while the stopper is attached, the liquid injection port of the liquid injection passage can be closed off with a flap, and the covering member can be removed. Even in the closed state, it is possible to prevent dust and small insects from entering the liquid injection passage, resulting in good hygiene.

(b) Since a knob member for operating the flap is provided at a position separate from the flap that closes the liquid injection port, the flap operation is sanitary and highly safe.

(c) Even if the device is equipped with a valve body for opening and closing the liquid injection passage and a flap for opening and closing the liquid injection port, the valve body and the flap can be opened and closed simultaneously with a single knob member. , the valve body and flap can be opened and closed easily.

(d) Even if the covering member is installed without forgetting to close the valve disc, the covering member will push the valve disc up in the direction of the valve closing operation via the flap, and the valve disc will be securely closed. The valve can be maintained in a closed state (the heat retention effect is improved and the liquid does not inadvertently flow out when the liquid container is tilted).

(e) Since the knob member is provided so that it can be horizontally moved in a direction different from that of the flap which is pressed down by the cover member, even if an external object collides with the knob member due to the liquid container falling over, This can prevent the flap from being opened due to careless operation of the knob member.

(f) Since the upper end surface of the knob member is located below the uppermost position of the flap when the liquid inlet is in the open position, the knob member will not cause problems even if it is covered with the covering member. The flap can be closed without any problems.

A stopper body 25 has a male thread 26 that is screwed into the main body 25 and has a liquid injection passage 27 formed therein, and a liquid injection passage 27 inside the stopper.
a valve body 41 that opens and closes the liquid inlet 27a of the stopper, and a flap 28 that covers the liquid injection port 27b of the liquid injection passage 27 in the stopper.
and a single knob member 45 that opens and closes the valve body 41 and the flap 28 at the same time.

The liquid injection passage 27 in the stopper is configured to vertically penetrate through the stopper main body 25, and the lower surface of the stopper main body 25 serves as a liquid inlet 27a, and a spout is located on the upper surface of the stopper main body 25 at a position closer to the outer periphery. A liquid injection port 27b is formed.

The valve body 41 includes a valve portion 42 that opens and closes the liquid inlet 27a from below, and a valve rod 43 above the valve portion 42. Further, the valve body 41 is biased in the upward valve closing direction by a spring 44.

The flap 28 is connected to the liquid injection port 27b of the liquid injection passage 27.
It has a cover plate 28a having an area that completely closes the area, and a downwardly directed engagement piece 28b that engages with the flap operating portion 48 of the knob member 45, as will be described later.
The flap 28 is pivoted at its middle portion to the lower surface of the upper plate of the plug body 25 with a pin 29.
The lid plate 28a can be rotated in an arc between the horizontal closed position shown in FIG. 1 and the upwardly inclined position shown in FIG. In the closed position of the flap 28, the upper surface of the flap 28 and the upper surface of the stopper body 25 are arranged to be substantially on the same plane.

As shown in an enlarged view in FIG. 2, the knob member 45 has a knob portion 46 for operation, a valve body operation portion 47 for pushing down the valve body, and a flap operation portion 48 for opening and closing the flap. This knob member 45
The knob portion 46 in the upper part of the plug body 25 is made to protrude upward by a slight height from the guide hole 25b provided in the upper surface 25a of the plug body, and the valve body operating portion 4
7 and the flap operation part 48 are located on the lower surface side of the upper plate of the stopper body 25, and are installed so as to be slidable horizontally in the outward and outward directions.

Further, the knob member 45 has a knob portion 46
The flap 2 whose upper surface meets the opening position of the liquid inlet
It is provided so as to be located considerably below the top end position of No. 8. As will be described later, this is done by covering the upper part of the stopper with the covering members 3 and 4 while the flap 28 is in the open position of the liquid inlet.
This is to prevent the knob member 45 from causing any trouble when pressing down the knob 8.

The valve element operation part 47 of the knob member 45 is a valve stem pushing part 47 that projects downward and pushes down the upper end of the valve element valve stem 43 to maintain the valve element 41 in the open state.
a, a sloped surface 47b that rises and slopes outward adjacent to the valve stem push-down portion 47a, and a recessed portion 47c that is continuous to the upper end of the sloped surface 47b and is not pressed against the valve body. There is.

The flap operating portion 48 of the knob member 45 is formed into a concave shape into which the downward engaging piece 28b of the flap 28 can be fitted and held. This flap operation section 48
Of course, the engaging piece 28b on the flap 28 side is engaged with the flap 28 so that the flap 28 can be opened and closed by sliding the knob member 45 in the inward and outward directions. They are engaged so that the knob member 45 can be slid inwardly and outwardly by operation.

When the knob portion 46 of the knob member 45 is slid outward, the concave portion 47c of the valve body operating portion 47 is located directly above the valve body valve stem 43 as shown in FIG. When the user pulls the engaging piece 28b of the flap 28 in the direction of closing the flap and slides the knob 46 inward, the valve stem push-down portion 47a of the valve body operating portion 47 closes the valve body as shown in FIG. A flap operating section 48 is located directly above the rod 43 and is installed so as to push out the engaging piece 28b of the flap 28 in the flap opening direction. When the knob member 45 is in the outward sliding state, the valve body operating portion 47
, the valve body 41 is maintained in the upwardly movable closed state by the biasing force of the spring 44, and the cover plate 28a of the flap 28 is maintained in the horizontal closed position. There is. Furthermore, when the knob member 45 is slid inward from the closed operation position (opening operation), the upper end of the valve stem 43 is pushed downward against the spring 44 by the inclined surface 47b of the valve body operation part 47, and the final As shown in FIG. 2, the lower surface of the valve stem push-down portion 47a comes into contact with the upper end of the valve stem 43, thereby maintaining the valve body 41 in the open state, and the flap operating portion 48 allows the flap 28 to be opened. is forced to open. flap 28
In the open state (the state shown by the solid line in FIG. 2), the cover plate 28a is maintained in an upwardly lifted position. In addition, at this time, the cover plate 28
The tip of a is adapted to protrude further upward from the upper end of the knob portion 46 of the knob member 45. In this way, by making it possible to open and close the valve body 41 and the flap 28 at the same time with a single knob member 45, even if the valve body 41 and the flap 28 are provided, the opening and closing operations of the valve body 41 and the flap 28 are possible. It becomes easy.

As a covering member to be placed on the outside of the plug body 2,
In this embodiment, two inner and outer tips 3 and 4 are employed. The outer tip 3 is screwed into a male thread 54 formed on the outer surface of the bottle mouth member 15, and the inner tip 4 is installed in the outer tip 3 and pressed downward by the inner surface of the outer tip 3. has been done.
In addition, when the two inner and outer tips 3 and 4 are attached, the inner bottom surface 4 of the inner tip 4 as shown in FIG.
The height of a is set to be considerably lower than the height of the tip of the flap 28 in the open position. Kotup 3,
4 is attached, push down the tip of the cover plate 28a of the flap 28 that is open on the inner bottom surface 4a of the inner flap 4, and move the flap 28 along the chain line 2 in FIG.
It is now displaced to the position indicated by 8'. Then, the flap 28 moves from the position shown by the solid line to the position indicated by the chain line 28'.
When pushed down to the position, the engaging piece 28b of the flap slides the knob member 45 outward to the position shown by the chain line.
a is positioned outward from the upper end of the valve element valve rod 43 so that the upper end of the valve rod 43 abuts against the lower end of the inclined surface 47b of the valve element operating portion 47. When the knob member 45 slides outward to the position shown by the chain line (the upper end of the valve stem 43 is in contact with the lower end of the inclined surface 47b of the valve element operating section 47), the valve element 41 is moved upward by the spring 44. As a result, the tip of the valve stem moves upward while moving the inclined surface 47b of the valve body operating portion 47 outward, and eventually the knob member 45 automatically moves to the closed operating position. By being moved, the valve body 41 is maintained in a closed state, and the flap 28 is also maintained in a closed state. Therefore, in this liquid container, even if both the inner and outer tips 3 and 4 are attached and the user forgets to close the valve, the knob member 4 can be operated in the valve closing direction via the flap 28 to close the valve body. 41 is always maintained in a closed state. Note that if the valve body 41 remains in the open state,
The heat retaining power is reduced and when the liquid container is tilted, the liquid inside leaks to the outside through the liquid injection passage 27, but this liquid container can solve these problems. Further, in this liquid container, the knob member 45 is provided such that the upper surface of the knob portion 46 is located below the uppermost position of the flap 28 in the liquid inlet open position, and for example, Even if the liquid container is overturned with the covering members 3 and 4 removed, the knob member 45 will not touch the covering members 3 and 4.
Since the knob member 45 is provided so that it can be pushed down and horizontally moved in a direction different from that of the flap 28, even if an external object collides with the knob member 45, the flap will not open if the knob member 45 is inadvertently operated. 28 can be prevented from being opened.

The handle device 6 includes a relatively long and hollow handle member 61 that serves as a substantial handle portion, a slide member 62 that is mounted so as to be slidable in the length direction within the handle member 61, and a slide member 62 that is slidable in the length direction within the handle member 61. Pin 64 at the top end
a rocking arm 63 that is bendably connected to the rocking arm 63;
and a soft cover 69 made of rubber or the like that covers the bent portion of the handle member 61.
This handle device 6 is attached to the outer surface of the container body 1 by having the upper end of the swinging arm 63 pivotally connected to the shoulder member 13 with a pin 9, and the lower end of the handle member 61 being pivotally connected to the bottom member 14 with a pin 9A. I am wearing it. This handle device 6
When dispensing a liquid or carrying the handle by the handle, the handle device 6 is bent as shown by the chain line 6' and separated from the side of the container body 1, and when dispensing a non-liquid or carried by the hanging string device 7, the handle device 6 is bent as shown by the chain line 6'. If it is compressed into a straight line (along the side of the container body 1), it will not get in the way.

The hanging string device 7 is constructed by attaching connecting members 72, 72, which are detachable from the shoulder member 13 and the bottom member 14, respectively, to both ends of a hanging string 71 having an appropriate length. When this hanging string device 7 is attached to the container body 1, the liquid container can be carried by hanging the hanging string 71 over the shoulder, and when carried by holding the handle device 6, the hanging string device 7 can be removed. You can also leave it there.

In the liquid container of this embodiment, when replenishing liquid, the liquid receiving container (both the inner and outer tips 3 and 4) is removed and the stopper 2 is removed to open the stopper hole 21, and the liquid is poured into the container body 12 from the stopper hole 21. Just inject it. Furthermore, when dispensing the liquid in the container body 12 into a cup or the like, the knob member 45 is opened with the stopper body 2 attached (as shown in FIG. 2, the valve body 41 and the flap 28 are respectively opened). ), by grasping the handle member 6 and tilting the liquid container toward the spout (liquid filling port) 27b, the liquid in the container body 12 can be poured out from the liquid filling port 27b through the liquid filling passage 27 in the stopper. I can do it.

In this embodiment, two inner and outer tips 3 and 4 are used as the covering member, but in other embodiments, only the outer tip 3 may be used as the covering member. In that case, it goes without saying that when the outer tip 3 is attached, it is necessary to be able to close the flap 28 which is in the open position with the outer tip 3.
