Description

[Detailed Description of the Invention] This invention relates to a spout device for a liquid container such as a pot, which has a built-in manual or electric liquid dispensing pump.

Liquid containers equipped with this type of pump are generally large in size and have a large capacity, and are also tall.

The spout pipe that leads the liquid dispensed by the pump to the outside of the container has its spout opening above the front of the container. If you place a liquid receiving container such as a pot on the same plane and perform the above-mentioned pouring,
Although there is a large head difference between the spout and the liquid receiving container, there is an inconvenience that droplets that scatter on the liquid surface of the liquid receiving container scatter around and wet the tabletop.

On the other hand, if you hold the liquid receiving container in your hand and hold it near the spout while pouring, you can prevent the droplets from scattering to the surrounding area as described above, but if the content is boiling water, the hand holding the liquid receiving container There is an inconvenience that high heat is transmitted.

In addition, this type of liquid container is most frequently used as a heat insulating container for hot water, and therefore, the inconvenience that the hand holding the liquid receiving container cannot withstand the heat is the biggest drawback of this type of container.

This idea guides the dispensing inner container from the spout to the bottom of the vessel body, and provides a removable dispensing auxiliary tube that can be expanded and contracted and at least moved back and forth, and is attached and used as necessary. The liquid to be dispensed can be guided to the optimal position in the order receiving container and dispensed without the disadvantages of the conventional method.Moreover, the passage extension by the dispensing auxiliary pipe device allows the liquid to be dispensed safely and securely from the bottom of the container. To provide a safe and convenient spouting device for a liquid container that can prevent siphon dispensing and sucking out of the contents by infants without impairing the guidance of the liquid container.

Therefore, this device is equipped with a content liquid dispensing pump and a dispensing pipe that leads out the content liquid dispensed by the pump to the outside of the vessel, and the spout of the dispensing pipe opens downward above the front of the vessel body. In a liquid container that is used as a liquid container, an attachment part is provided at an appropriate place on the surface of the container, a pipe joint part that is swingable at least in the front-rear direction of the container, and a dispensing device configured to be expandable and contractable in the length direction. An auxiliary pipe is provided, and the auxiliary pipe is removably attached to the above-mentioned mounting portion on the surface of the vessel, so that the spout of the spouting pipe faces into the opening at the upper end of the spouting auxiliary pipe with a gap.

When the auxiliary spout pipe is attached to the container, it receives the liquid to be poured from the spout and guides it to the lower part of the container. The height of the liquid, etc. and the position from the container body to which it is guided can be adjusted.

The spout of the spout tube faces the upper end of the spout auxiliary tube installed, thereby ensuring that the spouted liquid flows into the spout auxiliary tube, and the spout auxiliary tube thoroughly controls the above-mentioned adjustment. Guide you to the location.

When the spout faces the upper end of the auxiliary spout pipe, the gap between them allows the spouting pressure of the liquid to be poured out and the compressed air mixed in to be released into the atmosphere, allowing the liquid to flow quietly into the auxiliary spout pipe. It allows smooth flow into the pipe and prevents suction from reaching the pipe from the auxiliary pipe.

An appropriate number of rectifying ribs 42 in the axial direction are provided on the inner surface of the opening at the lower end of the expandable tube body 39 to prevent the liquid flowing out from the opening from scattering.

In the illustrated case, the attachment member 36 is fixed to the front surface of the exterior case 3 using a fixing means such as an adhesive tape 361.

In this way, the auxiliary pouring pipe 35 is attached to the container body 1, and the pipe joint part 34
It can be freely swung in the direction of the arrow A in the figure around , and by appropriately setting the interference of the O-ring 40 in the pipe joint 34, the swiveling can be locked at any position. It is also possible to do so.

In addition, the telescopic tube body 39 is moved vertically as shown by the arrow B in the figure using the lever 43, the entire length of the auxiliary pouring tube 35 is arbitrarily adjusted, and the fit with the O-ring 41 is appropriately determined. It can be locked in any adjusted position.

FIGS. 3a and 3l) are views showing other embodiments of the auxiliary pouring pipe 35 and the pipe joint part 34.

At the upper end of the swing tube 38A whose upper end is shaped like a funnel,
A square shaft 44 is provided through the upper end, or shafts (not shown) are provided protruding from both sides of the upper end, and when the square shaft 44 is provided, both ends thereof are formed into normal cylindrical shaft parts, and the above-mentioned mounting is carried out. both ends of the shaft 44 are pivotally connected to a mounting frame 37a' instead of an arm, and
A friction engagement means (not shown) for locking the swinging tube 38A at an arbitrary swinging position is attached to the mounting frame 37a' and the swinging tube 38A.
Alternatively, a pipe joint part 34 is provided between the shaft 44, which allows the swinging tube body 38A to swing in the front-rear direction of the vessel body 1, and which can be locked at any swinging position. A set screw 41A is screwed into the telescopic tubular body 39, and the tubular body 39 is structured so that it can be slid and locked at any position on the swinging tubular body 38, and a mounting frame 37a' is attached. The upper end of the auxiliary spout 35 faces the lower part of the spout 33 by engaging with the member 36A.

Note that, in the illustrated case, the mounting member 36A is shown as being directly fixed to the exterior case 3.

FIG. 4 is a diagram showing still another embodiment, in which an arm 37a is provided at the upper end of the mounting tube 37B, and a member 36B is fixed to the front of the exterior case 3 with screws or the like.
A spherical bulge 37b is provided at the lower end of the mounting tube 37B.

A spherical portion 38b is formed at the upper end of the swinging tube 38 and is slidable while applying a moderate frictional engagement force to the outer periphery of the spherical bulging portion 37b, and both 37b and 38b are fitted together. This constitutes the pipe joint part 34.

On the other hand, the telescopic tubular body 39B has a sliding friction member 41B biased by a spring 41b held at its upper end.
B is brought into pressure contact with the outer surface of the swinging tube body 38.

In this way, when the swinging tube body 38 is attached to the vessel body 1 and its upper end is exposed to the lower surface of the spout 33, it can be swung not only in the front-rear direction of the vessel body 1 but also in any direction in the left-right direction. By appropriately setting the frictional force between the spherical bulging portion 37b and the spherical portion 38b, it is possible to lock the telescopic tube body 39B in the desired swinging position, and also to swing the telescopic tubular body 39B. Pipe body 38
It can be made into a pouring auxiliary pipe 35 that can be locked at any position on B.

43 is a knob provided on the sliding friction member 41B.

FIG. 5 shows still another embodiment, in which a bellows-shaped flexible tube body 47 is fixedly attached to the upper end of the swinging tube body 38', and a pouring auxiliary tube 35 with the bellows portion serving as the pipe joint portion 34 is shown. It is composed of
The upper end of the bellows-shaped flexible tube body 47 is attached to the arm 37a and fixed to the front of the vessel body 1, and is removably fitted and locked to the member 36B.

That is, by forming the bellows part of the bellows-like flexible tube body 47 from a material having appropriate plasticity or by forming it from a commonly used flexible pipe, the swinging tube body 38' can be moved in either the front, back, left or right direction. The bellows can also be swung and held at that swiveling position, and by making the bellows part expandable and retractable in the length direction, the expansion and contraction function of the auxiliary pouring tube 35 can be satisfied.

In this case, the previously described telescopic tube 39.3 is attached to the swing tube 38.
It goes without saying that a telescopic function may be provided by fitting 9 B or the like.

The expansion/contraction and locking functions of the ejection auxiliary pipe 35 at the expansion/contraction position can be further modified in various ways as shown in FIGS. 6 to 9.

In FIG. 6, a spring plate 48 having elasticity that extends outward is attached to the lower end of the swing tube 38, and the elastic tube 39 C
A keyway-shaped concave groove 49 extending in the length direction is provided in the
A spring plate 48 is brought into elastic contact with the bottom surface of the groove 49, and with a moderate frictional engagement force applied between the two, the telescopic tubular body 39C can be slid in its length direction.

In FIG. 7, a serrated engagement member 51 is fixedly installed in a keyway-like groove 50 of a telescoping tube 39D, and an elastic protrusion made of a spring plate 52 is protruded from the lower end of a swing tube 38. This makes it possible to engage the retaining member 51 and lock the telescopic tube body 39D in a click-stop manner, and to arbitrarily change the locking position (the telescopic length of the auxiliary pouring tube 35). .

8a, b, and c show a vertical groove 54 having an appropriate number of lateral protruding grooves 53 on the surface of the swinging tube 38E, as shown in FIG. A stepped groove 55 is provided,
A protrusion 56 protruding from the inner surface of the extensible tube body 39E is inserted into the vertical groove 5.
4 and any side protruding groove 53, or the stepped groove 55 and an arbitrary position on the stairs, the length of the auxiliary pouring pipe 35 can be adjusted. Adjust.

9a and l), a pinch clip 57 of a size that can pinch the swinging tube 38 is attached to the upper end of the extensible tube 39F, making the auxiliary pouring tube 35 expandable and retractable. The tube body 39F can be locked in any position.

Furthermore, a concave groove 58 that bulges outward in the radial direction is provided on the inner surface of the lower end opening of the extensible tube body 39F, so that when the liquid contained in the liquid container is poured out, the groove 58 that extends downward along the inside of the pouring auxiliary tube 35 is formed. This prevents a single drop from dripping from the opening of the telescoping tube 39F. By doing this, when the liquid receiving container such as a dropper is removed from below the pouring auxiliary tube 35, the table, etc. This can prevent drops from accidentally dripping onto the surface.

It goes without saying that the above embodiments can be implemented in combination with each other.

According to this idea, the auxiliary pouring tube can be attached to and detached from the container body, so if it is a liquid receiving container whose mouth can reach near the spout of the pouring tube, it can be removed and out of the way, and other liquid receiving tubes can be removed. When attached to the container, the dispensed contents can be guided to the optimal position by expanding and contracting and rocking back and forth, so no matter what kind of container it is in place, it will not spill out and will not miss the target. Can be injected.

The spout of the spouting tube faces the upper end of the spouting auxiliary tube attached to the container body, and the liquid to be poured can be reliably flowed into the spouting auxiliary tube without leaving anything behind. The gap between the spout and the upper end of the auxiliary spout pipe allows the dispensing pressure of the liquid to be poured out and compressed air mixed in to be released into the atmosphere, allowing the liquid to be poured into the auxiliary spout pipe. Since the suction action is not applied from the side of the auxiliary spout pipe to the side of the spout pipe, the liquid can be safely injected through the auxiliary spout pipe without splashing or disturbance of the liquid flow. This is achieved, and the natural outflow of the liquid content due to the siphon phenomenon through the auxiliary dispensing tube and the suction of the liquid content by infants and the like are prevented.

Furthermore, since the spout auxiliary pipe is attached to the vessel body, the passageway connection with the spout with the gap can be easily achieved without any special fitting or structure, and it can be easily applied to conventional equipment. In addition, the injection auxiliary pipe and its attachment/detachment structure are simple and can be provided at relatively low cost.
