【発明の属する技術分野】
本発明は注出容器に関する。
【0002】
【従来の技術】
注出容器が次亜塩素酸ナトリウム等を成分とするクリーナ剤等を収容し、保管中に発生した分解ガスが容器本体の内圧を上昇させるものにあっては、注出容器の容器本体又はキャップの開栓時に内容液が注液口から自然吐出する虞がある。
【0003】
従来の注出容器として、実公平1−28033号公報の図17に記載の如く、キャップに注液口と通気口を設け、キャップの表面に沿って摺動自在に設けた栓体の中空通路を注液口に位置付ける開栓操作の途中で、該中空通路を通気口に一旦連通させて容器本体の内圧を通気口から放出するものがある。ところが、この注出容器では、栓体の中空通路に前回注液時の内容液が残留した場合、次の開栓操作で中空通路が通気口に連通したときに、容器本体の内圧により残留内容液が飛ばされる虞がある。
【0004】
実公平1−28033号公報の図1のものは、キャップに設けた注液口と通気口のそれぞれを開閉する注液開閉部と通気開閉部を備えた開閉部材をキャップの表面に沿って摺動自在に設けた。そして、開閉部材は、開栓操作により、注液開閉部で注液口を開くと同時に、通気開閉部で通気口を開き、容器本体の内圧を放出可能としている。
【0005】
【発明が解決しようとする課題】
▲1▼しかしながら、実公平1−28033号公報の図1のものは、開閉部材により注液口と通気口を同時に開くから、容器本体の内圧が通気口から放出されるだけでなく、この内圧が内容液を注液口から吐出させる虞がある。
【0006】
本発明の課題は、容器の内容液の分解等により発生した分解ガスによる、又は、容器内の温度上昇による容器内の内圧上昇により、注出容器の開栓時に内容液が注液口から自然吐出するのを防ぐことにある。
【0007】
【課題を解決するための手段】
請求項1の発明は、注液口と通気口が設けられたキャップと、キャップが設けられる容器本体とを有してなる注出容器において、注液口を開閉する注液開閉路と通気口を開閉する通気開閉路を備えた開閉手段をキャップに設け、開閉手段は、注液開閉路により注液口を閉じ状態から開こうとする開き操作の途中で、通気開閉路により通気口を閉じ状態から開くようにしたものである。

【0009】
キャップ12は容器本体11に打ち込み(ねじ込みでも可)により固定され、容器本体11の内部に連通する大径の注液口12Aと小径の通気口12Bを並置している。注液口12Aにはディップチューブ15が接続されている。
【0010】
図3に示す如く、ノズル13はノズル途中で折れ曲がるへの字状をなし、その下端部をピン16によりキャップ12に回動自在に枢着され、キャップ12の天面に設けた凹部17に納まる格納状態から、例えば90度回動せしめられる使用状態へと回動可能にされる。ノズル13は、下端外周面を円弧面又は球面の封止面18とし、この封止面18をキャップ12の円弧面又は球面の回転面19に密着状態で摺接される。キャップ12の注液口12Aと通気口12Bは回転面19に開口する。
【0011】

【0015】
(C)ノズル13を更に引き上げて例えば90度回動させた最終回動状態では、図5に示す如く、キャップ12の通気口12Bはノズル13の封止面18により閉じられ、キャップ12の注液口12Aはノズル13の注液開閉路21A(中空通路13A)により開かれる。これにより、容器本体11のスクイズにより、洗浄液をディップチューブ15経由でノズル13の注液開閉路21A(中空通路13A)から注出可能とする。
【0016】
即ち、ノズル13は、上述(a)〜(c)において注液開閉路21Aにより注液口12Aを開こうとする開き操作の途中で、通気開閉路21Bを構成する溝13Bが通気口12Bを通過する上述(b)の中間回動状態で、当該通気開閉路21Bにより通気口12Bを閉じ状態から開き、容器本体11の内圧を通気開閉路21Bから放出可能とする。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a dispensing container.
[0002]
[Prior art]
If the dispensing container contains a cleaner containing sodium hypochlorite, etc., and the decomposition gas generated during storage increases the internal pressure of the container body, the container body or cap of the dispensing container When the container is opened, the content liquid may be spontaneously discharged from the liquid inlet.
[0003]
As a conventional dispensing container, as shown in FIG. 17 of Japanese Utility Model Publication No. 1-28033, a cap is provided with a filling port and a vent, and a hollow passage of a plug body slidably provided along the surface of the cap. In the middle of the opening operation of positioning the liquid at the liquid inlet, the hollow passage is once communicated with the vent to release the internal pressure of the container body from the vent. However, in this dispensing container, if the content liquid at the time of the previous injection remains in the hollow passage of the stopper, when the hollow passage communicates with the vent hole in the next opening operation, the residual content is caused by the internal pressure of the container body. There is a risk that the liquid will be splashed.
[0004]
In FIG. 1 of Japanese Utility Model Publication No. 1-28033, an opening / closing member having a liquid injection opening / closing portion and a ventilation opening / closing portion for opening and closing a liquid injection opening and a ventilation opening provided in a cap are slid along the surface of the cap. It was provided movably. The opening / closing member opens the injection port at the liquid injection opening / closing section by opening the opening, and at the same time, opens the ventilation port at the ventilation opening / closing section to release the internal pressure of the container body.
[0005]
[Problems to be solved by the invention]
{Circle around (1)} However, in FIG. 1 of Japanese Utility Model Publication No. 1-28033, since the inlet and the vent are simultaneously opened by the opening / closing member, not only the internal pressure of the container body is released from the vent, but also the internal pressure. However, there is a concern that the liquid content may be discharged from the liquid inlet.
[0006]
An object of the present invention is to solve the problem that the content liquid spontaneously flows from the injection port when the dispensing container is opened due to a decomposition gas generated by decomposition of the content liquid in the container, or due to an increase in the internal pressure in the container due to a temperature increase in the container. The purpose is to prevent ejection.
[0007]
[Means for Solving the Problems]
The invention according to claim 1 is a pouring container comprising a cap provided with a liquid inlet and a vent, and a container body provided with the cap, wherein a liquid pouring opening / closing passage for opening and closing the liquid pouring port and a vent. The cap is provided with an opening / closing means having a ventilation opening / closing path for opening / closing the opening, and the opening / closing means closes the ventilation opening with the ventilation opening / closing path in the middle of the opening operation for opening the injection port from a closed state by the liquid injection opening / closing path. It opens from the state.

As shown in FIG. 1, the dispensing container 10 is an eyewash container, and has a flexible container main body 11, a cap 12, a nozzle 13 constituting an opening / closing means, and an eyewash cup 14. As shown in FIG. 2, the dispensing container 10 stands up by rotating the nozzle 13 with respect to the cap 12, fits the nozzle 13 into the slit 14 </ b> A of the eyewash cup 14, puts the eyewash cup 14 around the eye, and stands upright. The container body 11 is squeezed and the washing liquid is poured out of the nozzle 13 via the dip tube 15 to wash the eyes. The nozzle 13 pours the cleaning liquid from obliquely below the horizontal at an angle a (0 to 60 degrees), and receives the cleaned waste liquid in the eyewash cup 14.
[0009]
The cap 12 is fixed to the container main body 11 by driving (or screwing in), and a large-diameter liquid inlet 12A and a small-diameter vent 12B communicating with the inside of the container main body 11 are juxtaposed. A dip tube 15 is connected to the liquid inlet 12A.
[0010]
As shown in FIG. 3, the nozzle 13 has a U-shape that bends in the middle of the nozzle, and its lower end is pivotally connected to the cap 12 by a pin 16 so as to be rotatable, and fits in a recess 17 provided on the top surface of the cap 12. From the stored state, it can be turned to a use state in which it is turned, for example, 90 degrees. The nozzle 13 has an arcuate or spherical sealing surface 18 at the lower end outer peripheral surface, and the sealing surface 18 is slidably contacted with the arcuate or spherical rotating surface 19 of the cap 12 in a state of close contact. The liquid inlet 12A and the vent 12B of the cap 12 open to the rotating surface 19.
[0011]
The nozzle 13 constitutes the opening / closing means of the present invention, and includes a liquid injection opening / closing path 21A for opening / closing the liquid injection port 12A to / from the external space and a ventilation opening / closing path 21B for opening / closing the ventilation port 12B to / from the external space. The liquid injection opening / closing passage 21A is formed by a hollow passage 13A opening on the sealing surface 18 of the nozzle 13, and the ventilation opening / closing passage 21B is formed by a groove 13B provided on the outer wall of the sealing surface 18 of the nozzle 13.
[0012]
The opening / closing operation of the liquid inlet 12A and the vent 12B by the nozzle 13 is as follows.
[0013]
(A) In the stored state in which the nozzle 13 is housed in the concave portion 17 of the cap 12, the liquid inlet 12A and the vent 12B of the cap 12 are closed by the sealing surface 18 of the nozzle 13 as shown in FIG.
[0014]
(B) In an intermediate rotation state in which the nozzle 13 is pulled up from the concave portion 17 of the cap 12 and rotated, for example, 45 degrees, the liquid injection port 12A of the cap 12 is closed by the sealing surface 18 of the nozzle 13 as shown in FIG. In this state, the vent 12B of the cap 12 is opened by the ventilation opening / closing path 21B (groove 13B) of the nozzle 13 and communicates with the outside air. Therefore, the internal pressure of the container body 11 that has increased due to a temperature increase or the like is released from the ventilation opening / closing path 21B.
[0015]
(C) In the final rotation state in which the nozzle 13 is further pulled up and rotated, for example, 90 degrees, the vent 12B of the cap 12 is closed by the sealing surface 18 of the nozzle 13 as shown in FIG. The liquid port 12A is opened by a liquid injection opening / closing passage 21A (hollow passage 13A) of the nozzle 13. Thus, the squeezing of the container body 11 allows the cleaning liquid to be discharged from the liquid injection opening / closing passage 21A (hollow passage 13A) of the nozzle 13 via the dip tube 15.
[0016]
That is, during the opening operation for opening the liquid injection port 12A by the liquid injection opening / closing path 21A in the above described (a) to (c), the groove 13B constituting the ventilation opening / closing path 21B closes the ventilation port 12B. In the intermediate rotation state of (b) passing through, the ventilation opening 12B is opened from the closed state by the ventilation opening / closing path 21B, and the internal pressure of the container body 11 can be released from the ventilation opening / closing path 21B.
[0017]
According to the present embodiment, the following operations are provided.
{Circle around (1)} In the course of the operation of the liquid injection opening / closing passage 21A of the nozzle 13 to open the liquid injection opening 12A, the ventilation opening 12B is opened by the ventilation opening / closing passage 21B. When the liquid inlet 12A is opened, the internal pressure of the container body 11 has already been released from the vent 12B, and the internal pressure does not cause the content liquid to be discharged from the liquid inlet 12A. When the container body 11 in the upright posture is not squeezed, the liquid does not spontaneously come out from the liquid inlet 12A.
[0018]
(2) Since the liquid injection opening 12A and the ventilation opening 12B have separate systems for the liquid injection opening / closing passage 21A and the ventilation opening / closing passage 21B of the nozzle 13 communicating therewith, the internal pressure released from the ventilation opening 12B in the above-mentioned (1). However, there is no fear that the remaining liquid on the side of the liquid injection opening / closing passage 21A (the hollow passage 13A of the nozzle 13) will be blown.

The liquid injection opening / closing passage 41A is provided at the inlet (injection opening 32A side) of the hollow passage 33A of the nozzle 33, is formed by a small inner diameter sealing portion 42 fitted to the plug 37 of the cap 32, and is provided with a ventilation opening / closing passage 41B. Is formed by a large-diameter sealing portion 43 provided on the outer peripheral wall of the nozzle 33 and fitted to the annular projection 38A of the fitting surface 38 of the cap 32. The push-in end of the linear movement of the nozzle 33 is regulated at the position where the small inner diameter sealing portion 42 and the large outer diameter sealing portion 43 abut against the bottom of the concave portion 36, and the drawing end is the lower end of the large outer diameter sealing portion 43. The locking projection 43A is regulated at a position where it comes into contact with the annular projection 38A of the fitting surface 38. When the lower end locking projections 43A are formed at a plurality of locations, it is preferable that the lower end locking projections 43A be evenly arranged on the large outer diameter sealing portion 43 in terms of the linear movement operation of the nozzle 33 and the strength.
[0023]
The opening / closing operation of the liquid inlet 32A and the vent 32B by the nozzle 33 is as follows.
[0024]
(A) In the retracted state in which the nozzle 33 is housed in the concave portion 36 of the cap 32, as shown in FIG. 8, the liquid inlet 32A and the vent 32B of the cap 32 are connected to the liquid inlet opening / closing passage 41A of the nozzle 33 (small inner diameter sealing portion). 42), and is closed by the ventilation opening / closing path 41B (the large-diameter sealing portion 43).
[0025]
(B) In an intermediate lifting state in which the nozzle 33 is pulled up from the concave portion 36 of the cap 32, as shown in FIG. 9, the liquid inlet 32A of the cap 32 is connected to the liquid injection opening / closing passage 41A of the nozzle 33 (small inner diameter sealing portion 42). Although the closed state is maintained, the ventilation port 32B of the cap 32 is connected to the ventilation opening / closing path 41B of the nozzle 33 (the concave path 43B of the large outer diameter sealing portion 43 of the ventilation opening / closing path 41B is formed in the annular shape of the fitting surface 38 of the cap 32). (A gap passage is formed between the projection 38A and the projection 38A) and communicates with the outside air. Therefore, the internal pressure of the container body 31 that has increased due to a rise in temperature or the like is released from the ventilation opening / closing passage 41B.
[0026]
(C) In the final lifting state in which the nozzle 33 is further raised, as shown in FIG. 10, the ventilation port 32B of the cap 32 is closed by the ventilation opening / closing path 41B (the large outer diameter sealing portion 43) of the nozzle 33, and the nozzle 32 is closed. The liquid injection port 32A is opened by the liquid injection opening / closing path 41A of the nozzle 33 (the small inner diameter sealing portion 42 of the hollow path 33A). Thereby, the squeezing of the container body 31 allows the cleaning liquid to be discharged from the liquid injection opening / closing passage 41A (hollow passage 33A) of the nozzle 33 via the dip tube 35.
[0027]
That is, during the opening operation for opening the liquid injection port 32A by the liquid injection opening / closing path 41A in the above-described (a) to (c), the nozzle 33 forms the large outer diameter sealing portion 43 constituting the ventilation opening / closing path 41B. When the concave passage 43B passes through the annular convex portion 38A of the fitting surface 38 of the cap 32, the vent opening 32B is opened from the closed state by the ventilation opening / closing passage 41B, and the internal pressure of the container body 31 is increased. Can be released from the ventilation opening / closing path 41B.
[0028]
According to the present embodiment, the following operations are provided.
{Circle around (1)} While the liquid injection opening / closing passage 41A of the nozzle 33 opens the liquid injection opening 32A, the ventilation opening 32B is opened by the ventilation opening / closing passage 41B. When the liquid inlet 32A is opened, the internal pressure of the container body 31 has already been released from the vent 32B, and the internal pressure does not cause the liquid content to be discharged from the liquid inlet 32A. When the container body 11 in the upright posture is not squeezed, the liquid does not spontaneously come out from the liquid inlet 12A.
[0029]
(2) Since the liquid injection port 32A and the ventilation port 32B have separate systems for the liquid injection opening / closing path 41A and the ventilation opening / closing path 41B of the nozzle 33 communicating therewith, the internal pressure released from the ventilation port 32B in (1) above. However, there is no danger that the remaining liquid on the side of the liquid injection opening / closing passage 41A (the hollow passage 33A of the nozzle 33) is blown.
[0030]
The present invention is not limited to a cap provided with a nozzle capable of freely rotating or linearly moving, and is not limited to the use of the nozzle as opening / closing means, but includes a plug provided slidably along the surface of the cap. Can also be applied to containers that use as opening and closing means.
[0031]
In addition, the spouting container of the present invention has an upright posture and a liquid discharge port formed above, and is not limited to a squeeze container with a dip tube, and is not limited to an eyewash container.
[0032]
【The invention's effect】
As described above, according to the present invention, it is possible to prevent the content liquid from spontaneously discharging when the spout container is opened.
