Description

[Detailed description of the invention] (Industrial application field) The present invention is a non-filling type liquid container in which the liquid inside the inner container can be poured out using pressurized air from an air pump. It sometimes concerns a safety device for regulating pump operation.

(Prior Art) FIG. 5 shows a conventional pump-filling liquid container equipped with a safety device for regulating pump operation when liquid is not being filled. This conventional safety device for a pump-type liquid container includes a lock ring 71 provided at the bottom of a pump push plate 61 installed on the top of an air pump 59, and an operation knob 72 for operating the lock ring 71 that is moved horizontally. By rotating the pump push plate 61, the downward movement of the pump push plate 61 can be restricted or released. This lock ring 71 has a mounting arm 71a provided on a part thereof.
By fixing the mounting arm 71a and the operating knob 72 with screws 80, with the lip of the knob sliding hole 69 provided on the top surface of the lid body 58 being sandwiched between the upper and lower surfaces of the operating knob 72, It is attached to the lid body 58.

However, in this conventional safety device for a pump-type liquid container, the lock ring and the operating knob 72 are separate parts, and the screw 80 is required to secure the lock ring 71 and the operating knob 72, so the number of parts is reduced. In addition, there was a problem that screws had to be tightened in order to attach the lock ring 71, and the lock ring assembly work was troublesome.

In addition, the lock ring 71 used in this conventional pump injection type liquid container is constructed by molding a flat plate into an annular shape, so it is weak in terms of strength, and when the pump push plate is strongly pressed in the locked state, the lock ring 71 is There was a risk that the lock ring 71 would be deformed (deflected downward) or even damaged.

In addition, some conventional pump injection type liquid containers of this type have a structure in which a pump push plate and a lock ring that locks the pump push plate rotate together. In the case where the pump rotates with the pump, there is a problem that if the pump push plate is rotated by mistake, the lock may be released inadvertently.

(Purpose of the invention) In view of the above-mentioned problems with the safety device of the conventional pump injection type liquid container, the present invention reduces the number of parts, can be assembled with one touch, and improves strength. Another object of the present invention is to provide a safety device for a pump injection type liquid container that prevents the pump push plate from being inadvertently unlocked even if a horizontal rotational action is accidentally applied to the pump push plate. .

(Means for Achieving the Object) The present invention provides an air pump in the lid of a liquid container body housing an inner container, and blows pressurized air from the air pump into the inner container to blow air inside the inner container. A safety device for disabling pump operation when liquid is not being poured in a pump-filled liquid container that allows liquid to be poured out through a series of liquid pouring passages to the outside. A regulating lock ring is provided on the lid body,
An outer annular hanging wall and an operating knob are integrally molded on the lock ring, and the outer annular hanging wall is force-fitted to the lid so as to be horizontally rotatable, and the operating knob is assembled so as to protrude outside the lid. , a rotation regulating member is provided between the pump pushing plate and the air pump or the lid body, which releases the regulation by horizontal rotation of the operating knob, and restricts rotation of the pump pushing plate. It is characterized by the fact that it has been provided.

(Function) The safety device of the pump injection type liquid container of the present invention is as follows:
The lock ring, which has an integrally molded operation knob, is assembled to the lid by force-fitting, so there is no need for screws to assemble the lock ring, and the assembly process is simple (no need to tighten screws).
In addition, by integrally molding the outer annular hanging wall to the lock ring, the strength of the lock ring can be improved, and since the outer annular hanging wall is force-fitted to the lid body, the outer annular hanging wall is provided. Even if the lock ring is designed to improve its strength, the elasticity of the outer annular hanging wall in the inner and outer directions prevents the force-fitting operation from becoming difficult. Further, the rotation of the pump push plate is restricted by the rotation regulating member, so that even if an attempt is made to rotate the pump push plate by mistake, the pump push plate will not rotate.

(Embodiments) Some embodiments of the present invention will be explained with reference to Figs. 1 to 4. Figs. FIGS. 3 and 4 show pump-type liquid containers equipped with safety devices according to the second and third embodiments, respectively.

The pump-injection type liquid container shown in FIGS. 1 and 2 has an inner container 5 made of a vacuum double bottle housed in an outer case 4, and a dish-shaped lower opening member 6 disposed in the upper part of the outer case 4.
A lid unit 2 comprising a bellows type air pump 9 and a pump pusher plate 11 accommodated in a lid body 8 is placed on top of a liquid container main body 1 which is placed and fixed, and the liquid to be dispensed is It is constructed with a series of liquid pouring passages 10 for guiding the liquid to the outside.

The liquid spouting passage 10 includes a liquid guide pipe unit 3 formed by attaching a vertically oriented liquid pumping pipe 13 and a horizontally oriented liquid spouting pipe 14 to a stopper 12, and a distal end discharge port 14a of the liquid spouting pipe 14 below. Continuously installed pouring auxiliary pipe 15
It is made up of.

The pump push plate 11 is formed in the shape of a circular inverted container with a peripheral wall 16 of an appropriate height. The pump press plate 11 is installed so as to be able to slide vertically inside a cylindrical wall 17 formed at the upper center of the lid 8 (directly above the air pump 9). Further, this pump press plate 11 is not rotated with respect to the lid body 8 or the air pump 9. In this first embodiment,
By making the engagement piece 23 formed vertically on the inner surface of the peripheral wall 16 of the pump push plate 11 and the engagement piece 24 formed vertically on the upper surface of the air pump 9 abut against each other, the pump push plate 11 and the air pump 9 are arranged so that they do not rotate relative to each other. Incidentally, both of the engaging pieces 23 and 24 serve as rotation regulating members within the scope of the utility model registration claim.

In this pump injection type liquid container, when the pump push plate 11 is pressed, the air pump 9 contracts.
Pressurized air from the air pump 9 is blown into the inner container 5 through the air passage 20 in the stopper 12, and the pressurized air causes the liquid in the inner container 5 to pass through a series of liquid dispensing passages 10. It is designed so that it can be poured outside.

A safety device is provided within the lid 8 to disable pump operation when liquid is not being injected. A lock ring 21 is used in this safety device.

This lock ring 21 is attached to the cylindrical wall 1 of the lid body 8.
A cylinder wall portion 25 having an inner diameter slightly larger than the outer diameter of 7.
an annular upper plate portion 26 extending outward from the upper end of the cylindrical wall portion 25; and an outer annular hanging wall 27 extending obliquely downward from the outer end of the upper plate portion 26.
and an operation knob 22 that protrudes upward from the upper surface of the upper plate portion 26 are integrally formed. The inner surface of the cylindrical wall portion 25, the upper surface of the upper plate portion 26, and the outer surface of the outer annular hanging wall 27 of the lock ring 21 have substantially the same shape as the back side of the lid body 8. Further, in the outer annular hanging wall 27, there are a plurality of narrow notch grooves 28, 28, 28, 28, etc. (for example, 8 ~10 pieces) are formed. This cutout groove 28 is provided so that the outer annular hanging wall 27 can be easily bent when the lock ring 21 is assembled to the back side of the lid body, as will be described later.

A knob sliding hole 19 is formed in the upper plate part 18 of the lid body 8 to allow the operating knob 22 of the lock ring 21 to slide in the horizontal rotation direction while protruding above the lid upper plate part 18. There is.

Further, on the inner surface of the outer peripheral wall 31 of the lid body 8, a plurality of (three in this embodiment) small protrusions 32, 32, 32 integrally protrude inward at equal intervals in the circumferential direction. It is formed. Each of these small protrusions 32,
32, 32 are for supporting the lock ring 21 from below, and each of the small protrusions 32, 3
2, 32 are located at the same height as the lower edge 27a of the outer annular hanging wall 27 of the lock ring 21 when the upper surface of the lock ring 21 is in contact with the back surface of the lid 8, and the small protrusions 32, 32, The diameter of an imaginary circle passing through each inner end of each of the small protrusions 32, 32, 32 is the outer annular hanging wall 27.
The diameter of the lower end edge 27a is set to be slightly smaller than that of the lower end edge 27a.

This lock ring 21 is attached to the back side of the lid 8 by force fitting. That is, when the lock ring 21 is strongly pressed from the back side of the lid body 8 with the operating knob 22 positioned directly below the knob sliding hole 19, the lower part of the outer annular hanging wall 27 of the lock ring 21 After the outer surface abuts against the small protrusions 32, 32, 32 on the lid body side, the outer annular hanging wall 27 is bent inward so that its lower edge 27a climbs over each of the small protrusions 32, 32, 32. It comes to be assembled while being placed on the upper surface of each of the small protrusions 32, 32, 32. At this time, the operating knob 22 is made to protrude upward through the knob sliding hole 19, and by operating the operating knob 22 in the horizontal rotation direction within the range of the knob sliding hole 19, the lock ring 21 is moved inside the lid body 8. It is designed so that it can be rotated in the horizontal direction while being supported by each of the small protrusions 32, 32, 32.

On the outer surface of the lower end of the peripheral wall 16 of the pump pusher plate 11, a plurality (for example, eight) outward protrusions 30, 30, . . . are formed at predetermined equal intervals in the circumferential direction. Each of these outward protrusions 30, 30...
In the extended state of the air pump 9, the cylindrical wall 17 of the lid body 8
It is designed to abut against the bottom surface of the.

On the other hand, on the inner surface of the lower end of the cylindrical wall portion 25 of the lock ring 21, there are a plurality of (e.g. eight) inward protrusions 29, 29, spaced equally apart from the outward protrusions 30, 30, . is formed. These inward protrusions 29, 29... can be formed by rotating the lock ring 21 in the horizontal direction.
The outward protrusions 30, 30 on the side of the pump push plate 11...
It engages or disengages in the vertical direction. And each of these inward protrusions 29, 29
... is located directly below each of the outward protrusions 30, 30..., even if the pump press plate 11 is pressed, the outward protrusions 30 abut against the inward protrusions 29,
The pump push plate 11 cannot be moved downward (pump operation restricted state). Conversely, each inward protrusion 29, 2 on the lock ring 21 side is placed below each outward protrusion 30, 30... on the pump push plate 11 side.
9 is not positioned, when the pump push plate 11 is pressed, each of its outward protrusions 30, 30... can move downwardly through between the inward protrusions 29, 29...,
Therefore, pump operation becomes possible. Note that when the inward protrusion 29 on the lock ring 21 side and the outward protrusion 30 on the pump push plate 11 side are engaged in the vertical direction, a "stop" indication appears in the knob sliding hole 19, and vice versa. The inward protrusion 29 and the outward protrusion 3
0 is not engaged in the vertical direction, it is preferable that an indication of "out" appears in the knob sliding hole 19.

In addition, the pump push plate 11 does not rotate because the engagement piece 23 formed on the pump push plate 11 side and the engagement piece 24 formed on the air pump 9 side abut each other. This eliminates the problem of the lock ring 21 being unlocked due to the pump push plate 11 being rotated by mistake.

In the safety device of the second embodiment shown in FIG.
A plurality of (for example, three) cutout windows 36 are formed at equal intervals in the circumferential direction at the bottom corners of. Each cutout window 36 is formed at an angle of, for example, 30° in the circumferential direction. On the other hand, Lock Ring 2
1, an inner annular wall 38 serving as a sliding cylinder of the pump push plate 11 and a relatively short outer annular hanging wall 39 provided at a predetermined distance apart from the inner annular wall 38 are connected at the upper end and are integrated into one body. It is formed and constructed. or,
On the outer surface of the outer annular hanging wall 39 of the lock ring 21, each of the cutout windows 36 (three in total) is provided.
Outward engaging claws 40 (total of three) that can be engaged with are formed. And this lock ring 21
is pressed from above the lid body 8, and the engaging claw 40
is assembled to the lid body 8 by pressing and sliding it down along the inner surface of the recessed step 35 and engaging the engaging claw 40 with the upper edge 36a of the notch window 36. . Note that the operating knob 22 is made to protrude upward from the upper surface of the upper plate portion 18 of the lid body 8. When the lock ring 21 is rotated by pinching the operating knob 22, the locking claw 40 locks into the notch window.
It is designed to be able to rotate with respect to the lid body 8 within a range that abuts the left and right end surfaces of the lid body 6 .

In the safety device of the third embodiment shown in FIG. 4, on the outer surface of the outer annular hanging wall 47 of the lock ring 21,
Multiple pieces at equal intervals in the circumferential direction (for example, 3 pieces)
, and the outer peripheral wall 31 of the other lid body 8.
An annular shelf portion 42 is formed on the inner surface of the holder. When assembling this lock ring 21, as in the case of the first embodiment, the lock ring 21 is moved from the bottom side of the lid body 8 toward the back surface of the lid body so that the engaging pawl 41 on the side of the lock ring 21 is in an annular shape. Press until it goes over the top of the shelf 42. Further, in the safety device of this third embodiment, the lock ring 21 is connected to the air pump 9.
By abutting or releasing the abutment against the top plate 43, the pump operation is regulated or deregulated. That is, a plurality of cutouts 44 are formed on the outer circumference of the pump top plate 43 and are recessed inward at appropriate intervals in the circumferential direction, and the cutouts 44 pass through the lower end of the outer circumference of the lock ring 21 on the other hand. A plurality of inward protrusions 46 are formed corresponding to the formation position of the notch 44 with which the non-notched portions 45 of the outer circumference of the pump top plate abut, and the inward protrusions 46 are located directly below the notch 44. When the pump top plate 43 is located at 1, the pump top plate 43 can be moved downward, and when the inward protrusion 46 is located directly below the non-cutout portion 45 on the outer periphery of the pump top plate, the pump top plate 43 cannot be moved downward. I am trying to make it so that

In addition, in the pump injection type liquid containers of the second and third embodiments shown in FIGS. 3 and 4, the parts omitted from illustration and the parts omitted from explanation are the same as the pump injection type liquid containers of the first embodiment. Therefore, the first embodiment will be referred to.

(Effects of the invention) The safety device of the pump injection type liquid container of the invention has the following effects.

(1) Since the lock ring 21 with the operation knob 22 integrated therein is assembled to the lid 8 by force-fitting, there is no need for screws for assembling the lock ring 21, and the assembly work is simple. .
