Description

[Detailed Description of the Invention] Technical Field The present invention relates to a liquid container such as a thermos flask whose content is dispensed by a manual or electric pump;
In particular, the present invention relates to a liquid container with a hand handle and a variable spout height.

PRIOR ART This type of pump dispensing liquid container has a large capacity because it can pour liquid while it is stationary, and a hand handle to carry it has become essential. On the other hand, a convenient pump has already been proposed in which the liquid content dispensed from the pump is guided from the top to the bottom of the container at the front of the container, and the lower end of the liquid injection port can be adjusted to a height that suits the liquid receiving container. (Utility Model Application Publication No. 162955, Publication No. 183759).

The spout height is adjusted by providing a vertically moving part in the downward guide path, which complicates the structure and reduces external force resistance. If the free end of the hand handle, which is lowered toward the front of the upper body for handling the equipment, comes into contact with this vertically moving part, it is likely to break down, and even if this does not result in a failure, the structure for supporting the vertically moving part and stabilizing the position will be damaged. This will cause loosening and shorten the lifespan.

Objective: The present invention provides a hand handle with a variable spout height, which solves the above-mentioned drawbacks of the conventional method without complicating the structure or increasing costs by devising a method of providing a downward guide path for the free end of the hand handle. The purpose is to provide liquid containers.

Configuration This invention includes a liquid content pouring pump, a pouring path that guides the liquid content poured out by the pump to the outside,
In a liquid container equipped with a hand handle whose ends are pivotally supported so as to undulate back and forth on both sides of the container, the liquid container is located at the front of the container so as to guide the dispensing contents downward from the top of the container through a dispensing channel. A downward guide path having a vertically movable part for adjusting the height of the lower spout is provided with a fixed part positioned and sized to receive the free end of the hand handle when it is laid down.

Function: When the hand handle falls down, the fixed part of the downward guide path contacts and catches the free end of the hand handle, thereby preventing external forces from falling down the handle from reaching the vertically moving part.

Embodiment The embodiment shown in FIGS. 1 to 6 will be described. Reference numeral 1 denotes a liquid container body, which forms a thermos flask in which a double vacuum bottle 3 is housed inside an outer case 2. A saucer-shaped shoulder 5 having a hot water supply port 4 communicating with the upper end opening of the bottle 3 is fixed to the upper end of the outer case 2, and a lid 7 with a built-in manual air pump 6 is disposed on the shoulder 5. , is pivotally attached 8 to the rear part of the shoulder part 5 and configured to be openable and closable. The lid 7 has an operating portion 9 protruding from its front surface, a lock lever 12 pivotally connected to the lid 7 by a pin 10, and biased counterclockwise by a spring 11.

On the other hand, an operating rod 28 is provided, through which the pump 6 is inserted, and whose lower end faces the upper surface of the operating portion 23 of the valve 18. The rod 28 is urged downward by a spring 29 and supported on the upper wall of the pump 6. This is done by pressing down on the pressure plate 25, which moves the operating rod 28 downward via the spring 29, pushing down the valve 18 at its lower end, and pushing down the passage 21.
It has an open structure. Therefore, spring 29 is stronger than spring 20 which urges valve 18 upward.

By pressing down the pressure plate 25, the intake valve 26
The upper wall of the pump 6 is pushed down through the pump 6, and the air inside the pump 6 is forced into the bottle 3.
The content liquid is poured out of the container via 7 as described above. When the pressing force on the pressing plate 25 is released, the pressing plate 25, the pump upper wall, and the operating rod 28 return upward by the springs 24 and 29, and at this time, the intake valve 26 opens the intake port 27 and the atmosphere flows into the pump chamber. .

A long downward guide path B for guiding the liquid content further downward is provided in the dispensing path A near the outer surface of the container body 1 from an overhanging portion of the container body shoulder 5 on one side, and the lower end of the downward guide path B A spout portion 31 is formed at the top, which is bent so as to separate the tip spout 30 from the outer surface of the container body 1. The downward guide path B is inserted from above into the opening 32 of the beak-shaped portion 5a of the shoulder portion 5 that protrudes from one side of the container body 1, and is held detachably, and the content liquid is discharged from the discharge port 33 of the spout pipe 17. Base tube 34 intended to receive
and a vertically movable tip tube 35 which is fitted to the outer periphery of the base tube 34 so as to be movable up and down and has the spout section 31 at the lower end, and a movable tip tube 35 that covers the portion of the tip tube 35 except for the spout 30 and the upper end. A passage cover 36 is provided, and the cover 36 has a U-shaped upper half 3 in cross section.
Partially open hole 36 opened in top plate 36b of 6a
c' is the upper end flange 35a, 35 of the tip tube 35.
It is made to elastically fit into the groove 35c formed between b and move up and down integrally with the tip tube 35,
The lower half covers the spout portion 31 and serves as an operation knob 36c for adjusting the height of the spout 30.

On the outer surface of the container body 1, a fixed passage cover 37 is provided, in which the lower end of the base plate 37a is attached to the case 2 with screws 38, and the central protrusion 39 is inserted into the hole 40 of the case 2.
The downward guide path B is intended to be covered by a cover portion 37b integrally formed on the upper half of the base plate 37a. Furthermore, the upper half 36a of the passage cover 36 is inserted into the cover part 37b from below.
The base plate 3 is slidably inserted and guided.

1b is elastically engaged with the engagement unevenness 37e, the passage cover 36 and the tip tube 35 are moved and locked to arbitrary positions, and the spout 30 is adjusted to a desired height to match the liquid receiving container 42. It's meant to be stabilized. The upper end 37f of the fixed passage cover 37 is
It is fitted into and held in a cylindrical portion 5c formed on the lower surface of the beak-shaped portion 5a of the shoulder portion 5. This fixed passage cover 37
As a result, the boundary between the passage cover 36 and the base tube 34, which is displaced up and down when the height of the spout 30 is adjusted, is completely hidden, resulting in an aesthetically elegant configuration. Furthermore, the fixed passage cover 37
functions as a guide member for guiding the vertical movement of the passage cover 36 and as a member for positioning the upward movement of the spout portion 31 of the downward guide path B.
There is no need to provide a separate upward movement positioning mechanism, and the configuration can be simplified. Note that the spring 41 may be formed of a metal wire.

Of course, other methods can be used for the vertical movement structure of the tip tube 35 and its guiding method. cover 36,
37 protects the downward guide tube B from external force by covering it from beginning to end without exposing the downward guide tube B even from the mutual overlap due to the vertical movement accompanying the height adjustment of the spout 30 of the cover 36. This also prevents the operator's hands from touching it directly and causing burns or burns. In particular, the heat-resistant external force safety gap S between the covers 36, 37 and the guide path B enhances this effect.

There are U-shaped handles 4 on both sides of the shoulder 5 of the body 1.
The end portion 43a of 3 is pivotally supported by a pin 44 so as to be able to rise and fall freely. The handle 43 is laid down toward the front of the container 1 in a known manner, but when the downward guide path B is provided, the fixed passage cover 37 attached thereto
However, the free end 43a of the handle 43 is turned upside down.
Since the handle 43 is provided in such a position and size that the handle 43 is brought into contact with and received, the downward force of the handle 43 is not applied to the vertically movable portion of the downward guide path B. In this embodiment, the downward moving part on the downward guide path includes the vertically moving tip tube 35 and the movable passage cover 36 that covers it.
The free end 43b is prevented from coming into contact with the movable passage cover 36 extending from the fixed passage cover 37.

As a result, the handle 43, which is laid down forward of the vessel body 1, rotates as shown by the arrow A, centering on the point O in Figure 1, and its free end 43b moves downwardly on the structurally unstable downward guide. The vertical movement part, its support part, and position stabilizing mechanism will not be damaged or loosened.

The free end 43b of the handle 43, which is laid down forward of the container body 1, is brought into contact with the fixed passage cover 37, as shown by the phantom line in FIG.
As a result, even if the handle 43 falls forward with force due to its own weight or hooked force, the free end 43b will come into contact with the fixed passage cover 37 and will be guided downward. This prevents the passage from coming into contact with the container body 1 and causing damage or deformation.

Effects According to this invention, even if the hand handle that is pivotally supported on the side of the container falls down toward the front of the container, its free end will be in contact with the vertical movement part for adjusting the spout height of the downward guide path. Since they are not in contact with each other, no external force is applied to the unstable vertically moving parts, their support or position stabilizing means, causing damage or loosening. Moreover, this is achieved by the position and size of the fixing member when the downward guide path for the handle is provided, and does not complicate the structure or increase costs.
