Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pump-filling pot in which liquid in a liquid container can be poured out through a series of liquid passages to the outside by a pump device attached to the pot body.

In this type of pot, especially in a pot that employs a liquid container whose upper part has a smaller diameter than the body diameter, a relatively large volume cavity is formed between the upper small diameter part of the liquid container and the outer case. However, in conventional pump-type pots, this space is hardly utilized.

The present invention utilizes the space formed between the upper small diameter portion of the liquid container and the outer case to accommodate the tip portion of the liquid passage therein, and furthermore, the tip portion can be expanded and contracted in the horizontal direction. The object of the present invention is to provide a pump injection type pot whose overall structure is made compact by forming it into a tube.

The pump liquid injection pot of the present invention will be explained below based on the illustrated embodiment. The pump liquid injection pot of the present invention shown in FIGS. An outer case 4 accommodates an inner bottle 5 consisting of a vacuum double bottle.
A pot body 1 having a dish-shaped lower mouth member 6 placed and fixed on the upper part of the pot body 1, a lid body 2 which houses a type 9 air pump in the tongue which serves as a pump device 8 inside, a water conduit unit 11 and a telescopic tube. It is constituted by a liquid passage 10 consisting of 21.

The lid body 2 is pivotally attached to the upper part of the pot body 1 by a screw thread 3.

The medium bottle 5 has a thick body and a diameter smaller than the body diameter at the top, and the upper part of the shoulder 5a of the medium bottle 5 and the outer case 4
A relatively large-volume cavity 20 is formed between them.

A plug insertion hole 7 serving as a water supply port is formed approximately in the center of the lower mouth member 6.

Further, a hole 17 is formed in the front side of the lower eye member 6.

This hole 17 is for allowing the discharge port 14a at the tip end of the water conduit unit 11 to face downward.

The water conduit unit 11 is constructed by attaching a bottle inner tube 13 and a bottle outer tube 14 to a column 12. They communicate with each other.

The column part 12 is removably and airtightly fitted into the stopper insertion hole 7, and at this time, the bottle inner tube 13 is inserted into the medium bottle 5.

The outer bottle tube 14 is a short tube, and its tip 14c is opened downward.

Note that the tip 14a of the outer bottle tube 14 serves as a discharge port of the water conduit unit 11.

When the water conduit unit 11 is installed, its tip outlet 14a
faces downward from a hole 17 formed in the lower opening member 6.

A telescopic tube 21 is disposed below the discharge port 14a of the water unit 11 for guiding the liquid discharged from the discharge port 14a to the outside of the pot.

The expandable pipe 21 is constructed by connecting an outer pipe 22 and an inner pipe 23 in a telescopic manner, and further connecting and fixing a vertical pipe 24 above the base end 22a of the outer pipe 22.

Most of the proximal end 21a of this telescopic tube 21 is housed in a space 20 between the outer case 4 and the upper part of the shoulder 5a of the medium bottle.

In this way, the proximal end 21a of the expandable tube 21 is connected to the space 20.
By housing the pot inside, the space 20, which was hardly used in the past, can be effectively used, and the entire pot can be made compact.

The rear end of the base end 22a of the extensible outer pipe 22 is a wall surface 22c.
A connection port 25 that opens upward is formed at the base end portion 22a of the outer pipe.

The lower end of the vertical tube 24 is fixed to this connection port 25.

This vertical pipe 24 is for connecting the outer pipe 22 and the discharge port 14a of the water conduit unit 11, and the upper end of the vertical pipe 24 is hooked to the upper surface of the rim of the hole 17 of the lower mouth member 6.

In addition, when installing the water conduit unit 11, its tip outlet 1
4a faces into the upper opening of the vertical tube 24.

The tip portion 22b of the telescopic outer pipe 22 projects slightly forward from a hole 30 formed in the front surface 4a of the outer case 4.
Further, the outer pipe tip 22b is connected to the hole 30 in the outer case front surface 4a.
It is fixed to a support member 31 attached to.

The outer pipe tip 22b is opened forward from the front surface of the support member 31.

The telescopic tube inner vibe 23 has a slightly longer length than the outer pipe 22, and the tip 23b of the inner pipe 23 is exposed to the outside than the tip 22b of the outer pipe 22.

The tip 23b of the inner pipe 23 is opened downward.

Note that the inner pipe tip 23b serves as a spout for the telescopic tube 21.

The inner pipe 23 is connected to the outer pipe 22 at the inner pipe tip 23b.
A knob 26 is formed for moving the handle forward and backward.

A packing 27 is attached to the inner surface of the tip 22b of the outer pipe 22 to seal the space between the outer pipe 22 and the inner pipe 23.

When the inner pipe 23 is pushed inward as shown in FIG. It is designed to be sealed tightly.

The support member 31 attached to the front surface 4a of the outer case has an inner pipe tip 23b when the inner pipe 23 is pushed inward.
A shelf portion 32 is formed to close the opening 23c.

This shelf portion 32 is used to store the inner pipe 23 at its spout 23c.
It acts to prevent small insects and dust from entering.

When the inner pipe 23 is pulled out by pinching the knob 26, the base end 23a of the inner pipe is attached to the outer pipe 22 as shown in FIG.
Since it opens inside, it is possible to inject liquid.

. The air pump 8 housed in the lid 2 is pressed and driven by a pump operation plate 9 disposed on the top of the pump top plate.

Moreover, this air pump 8 communicates with the inside of the medium bottle 5 via a ventilation path 16 formed in the pillar portion 12 when the lid is closed.

To explain the usage and function of this pump liquid injection pot, when injecting liquid, the inner pipe 23 of the telescoping tube 21 is pulled outward by pinching the knob 26 (FIG. 2).

When the pump operation plate 9 is pressed, pressurized air from the air pump 8 is blown into the medium bottle 5 through the air passage 16 in the stopper, and the pressurized air causes the liquid W in the medium bottle to pass through the water conduit unit 11. The liquid W is primarily discharged from the distal end discharge port 14a, and the discharged liquid W passes through the vertical pipe 24 of the telescopic tube 21, the outer vibe 22, and the inner pipe 23, and is poured out from the distal end spout 23c. .

In addition, if the inner pipe 23 is pushed inward when the pot is not in use, the portion that protrudes outside the outer case 4 will become smaller, making it difficult for human bodies or other objects to collide with the protruding portion, thereby preventing the pot from tipping over. This has the effect of reducing the risk of

Next, to explain the effects of the present invention, the pump injection pot of the present invention has the following effects.

(1) The tip of the liquid passage 10 that communicates the inside and outside of the liquid container is a telescopic tube 21 that can be expanded and contracted in the horizontal direction, and the base 21a of the expandable tube 21 is connected to the outer case 4 and the small diameter above the shoulder 5a of the liquid container 5. Since it is placed in the space 20 formed between the parts,
The vacant space 20, which has been hardly used in the past
can be effectively used to make the entire pot more compact.

(2) When the telescopic tube 21 is contracted, the part that protrudes outward from the front surface of the outer case 4 becomes smaller, so the outer case can be made smaller during packaging, and the protruding part can be used to protect the human body or other objects when the pot is not in use. Objects are less likely to collide, reducing the risk of falling.
