Description

[Detailed description of the device] As shown in FIG. 1, for example, this device includes a pump 1 for dispensing a liquid content, and the liquid content to be dispensed is discharged from a dispensing pipe 2 by the action of the pump 1. A downward guide tube 4 that guides downward from the top of the container body 3 is passed vertically through a cover part 5 provided on the container body 3 to direct the liquid inlet 6 to a lower position, that is, to lower the pouring tube 2 to the container body 3. It opens at a sufficiently low level compared to the pouring lower which merely opens downward at the upper part, and the downward guide pipe 4 has its liquid receiving port 8 side base pipe 4a etc. partially or completely removable. This invention relates to a low-filling spout type liquid container.

The downward guide tube 4 can be easily cleaned and kept clean by attaching and detaching the whole or part thereof.

However, the waist downward guide tube 4 is handled separately from the vessel body 3 until it is dried after washing, so it is often difficult to attach it to the vessel body 3.
．． It will be forgotten.

When the lid 9 covering the upper end of the container 3 is open, whether or not the device is attached is determined by which of the lower guide tube liquid receiving port and the lower guide tube insertion port 21 faces the upper end of the container 3. In a design in which the downward guide tube to be attached and detached partially protrudes below the cover, as seen in Koshijitsu Publication No. 56-79242, it can be determined by the presence or absence of the protrusion.

However, even in that case, the state of attachment and detachment is not noticeable (and there is no big difference between them, so the guide tube 4
Even if the lid 9 is not attached, it is sometimes overlooked and the lid 9 is closed.

When the lid body 9 is closed, it is difficult to confirm whether the guide tube 4 is attached or not, and the device may be used without the guide tube 4 attached.

If the guide tube 4 is used without attaching or detaching the whole or part thereof, the dispensing contents discharged from the dispensing tube 2 will flow into the cover part 4 without being guided by the downward guide tube 4. , it flows down while dispersing to various parts.

For this reason, the area around the stationary part of the container body 3 becomes drenched with the liquid inside, and if the liquid inside is boiling water, there is a risk of burns.

In addition, if the cover part 5 is a part of the outer case 10 of the container body 3 and the guide tube 4 passes vertically between the outer case 10 of the container body 1 and the inner container 11, of course, as shown in FIG. , even if the guide tube 4 passes vertically through the cover part 5 attached to the outer surface of the vessel body 1 as shown in FIG.
A visual escape window 13 for the zero liquid level display tube 12 and a pilot lamp 14.15 provided in an electric kettle.
If the inside of the container body 3 is communicated with through an opening 16 for installing the cover part 5 or a mounting hole for attaching the cover part 5, the liquid to be poured out will also flow into the inside of the container body 3.

When the pouring content liquid flows into the container body 3, it accumulates in various parts within the container body 3 and is easily taken out, causing the outside of the container 3 to rust from the inside.

Furthermore, electric pots can damage the electric kettle and other electrical items, and there is also the risk of short circuits and leakage.

In order to solve the above-mentioned problem, this device has a downward guide tube that guides the dispensing contents discharged from the dispensing tube downward from the upper part of the container, and the entire cover is attached to a part of the cover provided on the container. In a low-filling-port type liquid container, which is partially removably connected vertically and has a liquid filling port opened at a low position, the bottom wall of the cover is partially removed (a part of the side peripheral wall is provided with a downward guide pipe). A means for confirming whether or not the downward guide tube is attached is provided to visually confirm from the outside whether or not the downward guide tube is attached when the whole or a portion is attached or detached.

Due to this structure, the means for checking the presence or absence of the downward guide tube is not only related to the use of the downward guide tube but also located in a part that can be easily observed from the outside during use, and has a unique visual effect on the normal appearance of the article. Displays whether or not it is installed.

To explain one embodiment below, FIGS. 3 to 7 show the display lever 18 that is linked to the attachment and detachment of the liquid receiving port side base tube 4a, which is the attachment and detachment part of the downward guide tube 4, and the indication lever 18. A means A for confirming whether or not the downward guide tube is attached or detached is provided with an attachment/detachment display window 19 provided in the cover part 5 so that the unattached display section 18a of the guide tube is displayed on the back side.

The cover part 5 includes a cover 5a attached to the outer surface of the container body 1,
At the upper end of the outer case 10, a beak-shaped portion 20a protrudes to one side of the container body 1 together with the spouting lower portion of the spouting pipe 2 of the mounted saucer-shaped shoulder member 20, which is vertically provided below the outer periphery and fitted into the top end of the cover 5a. The downward guide tube insertion port 21 is formed near the tip of the bottom wall 20b of the beak-shaped portion 20a.

The tip tube 4b on the liquid injection port side of the downward guide tube 4 is integrally covered with a vertically movable cover 22 that also serves as a knob, and is fitted into the cover 5a from below so as to be vertically movable, and a portion of the cover is inserted from above through the insertion port 21. It is telescopically fitted to the liquid receiving port side base tube 4a which is detachably inserted into the liquid inlet 5, thereby forming a downward guide tube 4 whose height of the liquid injection port 6 is adjustable.

The vertical movement cover 22 is guided in its vertical movement by rails 23 formed on the inner surfaces of both side walls of the cover 5a, and is provided with a click stopper 24 biased by a spring (not shown) at the inner bottom of the cover 5a. By elastic engagement with the engagement recess 25 on the back surface of 22, elastic locking is performed in stages at each height position.

A locking part 26 is also formed on the upper back side of the cover 22 to prevent the cover 22 from being pulled out from the cover 5a by engaging with the click stopper 24. When it is moved backward, the engagement with the locking part 26 is disengaged, and the cover 22 can be removed together with the liquid inlet side tip tube 4b as necessary.

The display lever 18 is designed to display whether or not the guide tube 4 is installed in conjunction with the attachment and detachment of the liquid receiving port side base tube 4a, which is normally attached and detached, of the downward guide tube 4, and its center portion is located on the inner surface of the upper end of the cover 5a. At the same time, the upper end passive part 18b faces into the insertion path from the insertion port 21 of the base tube 4a, and the lower end unattached display part 18a faces directly behind the attachment/detachment display window 19, and is biased by a spring 28. has been done.

The window 19 is equipped with a hemispherical transparent body 29 that protrudes toward the front side, and the display portion 18a is inserted into the recess 29a on the back side, so that the display portion 18a can be easily checked from outside the cover part 5. When the display section 18a is removed, the display section 18a is hardly or never seen from the outside.

As shown in FIGS. 3 and 4, when the base tube 4a is attached to the cover part 5, the display lever 18 causes the passive portion 18b to bulge out the outer periphery of the upper end of the base tube 4a. Pushed by the pushing part 30, the display part 18a rotates against the spring 28 from the imaginary line position in FIG. is the display section 18a
There will be no display.

This allows the user to confirm that the downward guide tube 4 is in a safe usable state with the base tube 4a attached.

When the base v4a is removed, the display lever 18 is rotated as shown in the imaginary line in FIG. facing into the back side recess 29a of the transparent body 29 at 19,
The display section 18a is brought into a display state that can be viewed from outside the window 19 as shown in FIG.

This allows the user to confirm that the downward guide tube 4 is in a dangerous unused state with no base tube 4a attached.

Here, the display section 18a serves as a so-called warning to inform the user of the danger of not attaching the base tube 4a and of the need to attach the base tube 4a.Due to its nature, if it is colored red, it will warn the user. can be intuitively recognized.

However, when the base tube 4a is attached, the display lever 18 does not display the display section 18 indicating that the base tube 4a is in a safe usable state.
It is also possible to display the information more actively by a, and to eliminate the display when the device is not worn.

Since the display section in this case is a safety display, the corresponding green or blue color may be used to intuitively sense safety and to notify the user that it is dangerous if there is no safety display.

Reference numeral 31 denotes a stopper detachably attached to the liquid supply port 32 at the center of the shoulder member 20, which connects the air supply passage 33 from the pump 1 to the inner container 11, and the air supply passage 33 into the inner container 11 through the air supply passage 33. It is equipped with a spouting pipe 2 that guides to the outside the content liquid that is pressurized by the air supplied to the tank and is about to be forced out.

Further, a lid body 9 is pivotally supported on the shoulder member 20, and a free end portion of the lid body 9 is elastically engaged with a locking portion 34 of the shoulder member 20.
It has a lock lever 35 that locks it in the closed state.

Reference numeral 36 is a liquid level display window provided at the base of the cover 5a attached to the container body 1.

FIGS. 8 and 9 show that the helicoidal piece 41 provided in the downward guide tube insertion port 21 and the helicoidal piece 42 on the outer periphery of the upper end of the base tube 4a are engaged to bring the base tube 4a into the installed state. Both helicoids are used to prevent the waist base tube 4a from accidentally falling off, and to seal the base tube 4a and the insertion port 21 by directly or through a seal backing 43 or the like. Only at the rotational position of the base tube 4a where the shaped pieces 41 and 42 are engaged to the end point of engagement regulated by the stopper piece 44, etc., there is a pusher that faces the passive part 18b of the indicator lever 18 and can push it. The moving part 45 is provided on the outer periphery of the upper end of the base tube 4a, and the pushing part 45 is formed by protruding a part of the outer circumferential surface of the base tube 4a in the circumferential direction.

In this case, the attachment display of the base tube 4a is performed only when the base tube 4a is in the normal attachment state in which both helicoidal pieces 41 and 42 are engaged by a predetermined amount, and when the base tube 4a is inserted into the insertion port 21. However, if the base tube 4a is not in the proper mounting state, the user is asked to confirm that it is not in the proper mounting state, thereby preventing unexpected inconveniences caused by the base tube 4a not being in the normal mounting state.

FIG. 10 shows an annular groove 51 formed on the outer periphery of the upper end of the base tube 4a by forming the passive portion 18b of the display lever 18 into a claw shape.
By elastically engaging with the base tube 4a, the base tube 4a can be locked in the installed state.

A special bulging part for pushing the passive part 18b of the display lever 18 is not provided on the outer periphery of the base tube 4a, but the base tube 4a
When inserted from the insertion opening 21, the driven part 18b is pushed back by contacting the upper slope 18c of the driven part 18b, and the display lever 18 can be smoothly rotated.

In each of the embodiments described above, the presence or absence of the downward guide tube 4 is indicated only by the presence or absence of some external display linked to its attachment, but some kind of positive display is provided for both the attachment and non-attachment indications. The waist display member that can be tilted can also be made of something other than the lever as described above.

Means A for checking whether or not the downward guide tube is installed in Figs. 11 and 12
is provided with a display slide 61 that slides up and down in conjunction with attachment and detachment of the base tube 4a, and a part of the display slide 61 is provided with a downward guide tube attachment display section 61a and an unattached display section 61b,
Both display sections 61a and 61b are switched to the attachment/detachment display window 19 for display as the base tube 4a is attached or detached.

The display slide 61 has its shaft portion 61c connected to the shoulder member beak portion 2.
Bearing portion 6 with grooves formed on the back surface of the downward peripheral wall 5b of 0a
2, and is urged upward by a spring 63.

Also, a display section 61a. 61b is provided at the lower end of the shaft portion 61c, and the attachment indicator 61a has a safe color such as green, and the unattached indicator 61b has a dangerous color such as red.

A passive piece 61d is formed at the upper end of the shaft portion 61c. When the base tube 4a is attached, a passive piece 61d is engaged with the downward staircase 64 on the outer periphery of the upper end and is pressed down.

When the passive piece 61d is not pressed down by the stepped portion 64, and therefore when the base tube 4a is not attached, the display slide 61 is in the upward movement position of the solid line due to the bias of the spring 63, and the unattached display portion is not shown to the window 19. 61b to confirm that the base tube 4a is not attached.

On the other hand, when the base tube 4a is attached, the stepped portion 64 pushes down the passive piece 61d, and the display slide 64 is moved downward against the spring 63.

As a result, the attachment display section 61a is positioned in place of the unattached display section 61b on the window 19, thereby confirming that the base tube 4a is attached.

In each of the above-mentioned embodiments, the presence or absence of the downward guide tube is displayed by some kind of display member separately provided to be linked to the attachment and detachment of the downward guide tube, whereas the confirmation of the presence or absence of the downward guide tube in FIG. Means A is intended to visually confirm a part of the base tube 4a directly through the attachment/detachment display window 19 to confirm whether or not it is attached.

A mounting display section 71 is provided at a location visible from the window 19 of the base tube 4a, and depending on whether it is visible from the window 19, it is easy to confirm whether or not the downward guide tube is attached or detached.

14 and 15, the display lever 18 as shown in FIG. 1 is provided with a switch 81 that is turned on and off in conjunction with the attachment and detachment of the base tube 4a, and the display lever 18 is guided downward on the imaginary line. When the tube is not attached, the switch 81 is turned off, and the heater 17 in the electric kettle is turned off regardless of whether the main switch 82 is turned on or off, thereby preventing heating of the contents.

As a result, even if the content liquid were to be poured out without the downward guide tube attached, the temperature would not be high, thereby avoiding danger.

The fact that heating is not performed by the heater 17 regardless of whether the main switch 82 is turned on can confirm that the downward guide tube is not attached, and can serve as a means for indicating whether or not the downward guide tube is attached.

Reference numeral 83 is a pilot lamp for indicating energization of the heater 17, which facilitates the above-mentioned confirmation.

In addition, in a liquid container of the type in which the content is dispensed by an electric pump, as shown by the dashed line in FIG. When the base tube 4a is not installed, the motor 84 can be turned off, and even if the dispensing switch 85 is turned on, the motor 84 will not operate and dispensing will not be possible.

In this case, it is possible to prevent the content liquid from being poured out without the downward guide tube being attached, which also serves as a more reliable means for confirming whether or not the downward guide tube is attached.

However, as shown in FIG. 14 by the imaginary line, the means A for checking whether or not the electrical downward guide tube is installed is composed of an attachment/detachment display window 19 and a lamp 91 provided on the back thereof. The pilot lamp 83 may be used as a normal energization indicator lamp instead of being provided as the display means A on the side circumferential wall of the cover part 5 except for the bottom wall.

In the state shown by the imaginary line in FIG. 15, the lamp 91 is turned on when the base tube 4a is not attached, and the transparent body 2 of the window 19
9 and the lamp 91 are colored in a dangerous color such as red.

The lamp 91 can be turned on and off to indicate that the downward guide tube is attached when turned on, or it can be provided with an attached indicator lamp and an unattached indicator lamp and turned on alternately.

As described above, if the presence or absence of the downward guide tube is electrically displayed, the display lever 18 in FIG. is no longer needed, and the helicoidal piece 4 of the switch 81 can be removed by attaching and detaching the base tube 4a as shown in FIG.
If the on/off operation is performed directly using the second part, the intermediary member between the base pipe 4a and the switch 81 can also be omitted.

FIG. 17 shows a circuit that turns on and off a lamp 91 using a switch 81. In addition to the lamp 91, a buzzer 92 is provided as shown by a dashed line to turn it on and off, and the main switch 82 is turned on. Nevertheless, when the downward guide tube 4 is not installed, the sound is emitted at the same time as the lamp 91 is turned on.

18 and 19, an electromagnetic stopper 101 is provided which is activated by a switch 81, and when the base tube 4a is not attached even though the main switch 82 is turned on, the stopper 101 is activated by the switch 81. The child 101a is projected as shown by the imaginary line, and prevents the pressing operation plate 102 of the pump 1 from moving downward, thereby preventing the lamp 91 from turning on and dispensing the liquid content.

20 and 21, a valve 112 is provided in the middle of the spouting pipe 2 and is normally open by the bias of a spring 111, and an electromagnet 113 that is turned on and off by a switch 81 is connected to the beak-shaped part of the shoulder member 20. 20a base, and the magnetic body operating part 112a of the valve 112 is opposed to the attraction part 113a of the electromagnet 113 within its electromagnetic attraction range, so that even though the main switch 82 is on, the base pipe 4a is When the electromagnet 113 is not attached, the switch 81 turns on the electromagnet 113, and the magnetic body operation part 112a is attracted to the attraction part 113a against the spring 111, the valve 112 is closed as shown by the imaginary line, and the lamp 91 is turned on. This is to prevent the contents from pouring out when the lamp lights up.

In each of the above-mentioned embodiments, only the case where the downward guide tube 4 is partially attached and detached, that is, the base tube 4a is attached and detached, is shown, but whether or not other parts are attached or detached or not, the presence or absence of attachment is checked whether the whole is attached or detached. This idea also applies in this case.

According to this invention, the means for checking whether or not the downward guide tube is installed is
In addition to being related to the use of the downward guide tube, it is located in a part that can be easily observed externally during use, and has a unique visual effect on the normal appearance of the product to indicate whether or not the downward guide tube is attached. To allow a user to easily and reliably confirm the presence or absence without oversight or misunderstanding.
