Description

  The present invention relates to a liquid discharge container and a container-containing liquid cleaning agent.

In general, containers that contain liquids such as liquid detergents, herbicides, insecticides, and machine oils as content liquids, and discharge the content liquids to an application target are known.
For example, for liquid applications such as toilets, drain pipes, bathrooms, and other liquid detergents, herbicides, machine oils, etc., press the body of the container with the hand and press the contents from the discharge hole. A squeeze-type container is used to discharge the liquid. This squeeze-type container is generally known to include a container main body that contains the content liquid, and a nozzle that is provided at the mouth of the container main body and has a discharge hole.
On the other hand, a trigger spray type container or an aerosol type container is used for applications to be applied over a wide range such as liquid detergents and insecticides for glass and furniture.

  The squeeze type container has a discharge hole formed at the top of the nozzle. For this reason, the squeeze-type container is in a state in which the discharge hole is directed downward (inverted state) and discharges the content liquid by pressing the body portion of the container body, but the discharge hole is directed upward. The content liquid could not be discharged in a dry state (upright state).

  In addition, since the trigger spray type container sucks up the content liquid by the dip tube suspended in the container body, the content liquid can be discharged in the upright state, but the content liquid cannot be discharged in the inverted state. The aerosol-type container can discharge the content liquid in an upright state in which the valve for discharging the content liquid is positioned above, but when it is inverted, only the propellant is discharged and the content liquid cannot be discharged.

In response to such a problem, an oil feeder has been proposed in which an oil feeding port and a cylindrical spool that opens and closes the oil feeding port are provided at the upper and lower parts of the pipe (for example, Patent Document 1).
Also proposed is a container in which an injection pipe is provided on the side of the suction pipe, a suction port is formed at both ends of the suction pipe, a water intake port is formed on the outer side of the suction port, and suction valves are provided at both ends of the suction pipe. (For example, Patent Document 2).
Alternatively, the container main body has a flow pipe connected to the ejection path of the valve and extending toward the bottom of the container, and the pipe has a first check valve at a tip portion extending toward the bottom of the container, A second check valve is provided in the vicinity of the valve connection position, and the second check valve is closed by pressing the valve body of the second check valve against the valve seat when the container is in the normal position. There has been proposed an aerosol container having a coil spring in which the valve body is pushed up by the contents to open when the container is in an inverted state (for example, Patent Document 3).

The physical properties of the content liquid can be determined depending on the application, and can be easily discharged from the discharge hole 20 when adhering and staying on the application target and pressing the body 34 with a finger. For example, the content liquid has a viscosity at 25 ° C. of preferably 10 to 500 mPa · s, more preferably 10 to 100 mPa · s.

 Next, the usage method of the liquid discharge container 1 of this embodiment is demonstrated using FIGS. FIG. 2 is a cross-sectional view of the liquid discharge container 1 for explaining how the content liquid is discharged in an upright state, and FIG. It is sectional drawing. FIG. 4 is a cross-sectional view of the liquid discharge container 1 for explaining a state in which the content liquid is discharged with the axis O1 of the container body 3 being horizontal (horizontal state).

 First, the discharge body 2 is removed from the opening 30 and the discharge unit 10 is taken out from the container body 3. Next, an arbitrary amount of content liquid is stored in the container body 3, the discharge unit 10 is positioned in the container body 3, and the discharge body 2 is fitted into the opening 30. In this way, the liquid discharge container 1 can produce a container-containing liquid detergent containing a liquid detergent in the container body 3 and a container-containing machine oil containing machine oil in the container body 3.

  A method of using the liquid discharge container 1 in the upright state will be described with reference to FIG. When the liquid discharge container 1 containing the content liquid 90 is brought into an upright state, the first valve body 62 closes the connection portion between the first cylinder 60 and the connecting portion 66, and discharges from the first cylinder 60. Close the flow path to 40. That is, the first check valve 6 is closed. On the other hand, the second valve body 72 is positioned in contact with the inner bottom surface of the second cylinder 70 and secures a flow path from the second cylinder 70 to the flow pipe 5. That is, the second check valve 7 is opened.

  When the body 34 of the liquid discharge container 1 in the upright state is pressed to reduce the volume in the container body 3, the content liquid 90 flows into the second cylinder 70 from the second communication hole 74. From the lower end 50 of the distribution pipe 5, the distribution pipe 5 and the discharge path 40 are sequentially passed through and discharged from the discharge hole 20. At this time, since the first check valve 6 is in a closed state, the gas (air) flowing into the first cylinder 60 from the first communication hole 64 causes the first valve body 62 to move into the first cylinder. It acts so that it may press on the connection part of 60 and the connection part 66. FIG. The first valve body 62 prevents the air that has flowed into the first cylinder 60 from flowing into the discharge path 40. In this manner, the liquid discharge container 1 of the present embodiment prevents the content liquid 90 and air from being mixed in the discharge path 40 and can discharge only the content liquid 90 from the discharge hole 20 in an upright state.

 A method of using the liquid discharge container 1 in the inverted state will be described with reference to FIG. When the liquid discharge container 1 containing the content liquid 90 is inverted, the first valve body 62 secures a flow path from the first cylinder 60 to the connecting portion 66. That is, the first check valve 6 is opened. On the other hand, the second valve body 72 is located on the upper end opening 76 side of the second cylinder 70 and closes the flow path from the second cylinder 70 to the flow pipe 5. That is, the second check valve 7 is closed.

  When the body portion 3 of the container body 3 is reduced by pressing the body portion 34 of the inverted liquid discharge container 1, the content liquid 90 flows into the first cylinder 60 from the first communication hole 64, The fluid is discharged from the discharge hole 20 through the connecting portion 66 and the discharge path 40 in order. At this time, since the second check valve 7 is in the closed state, the air flowing into the second cylinder 70 from the second communication hole 74 causes the second valve body 72 to move to the upper end of the second cylinder 70. It acts to press in the direction of the opening 76. The second valve body 72 prevents air that has flowed into the second cylinder 70 from flowing through the flow pipe 5 and into the discharge path 40. Thus, the liquid discharge container 1 of the present embodiment prevents the content liquid 90 and air from being mixed in the discharge path 40 and can discharge only the content liquid 90 from the discharge hole 20 in an inverted state.

A method of using the liquid discharge container 1 in a horizontal state will be described with reference to FIG. As shown in FIG. 4, the liquid discharge container 1 containing the content liquid 90 is placed in a horizontal state so that the second check valve 7 is below the axis O1.
Here, the movable direction F1 of the first valve body 62 intersects the axis O1 and the region from the intersection P1 to the bottom surface 36 is on the same side as the second check valve 7 with respect to the axis O1. positioned. For this reason, when the liquid discharge container 1 is in a horizontal state, the movable direction F1 of the first valve body 62 is inclined downward in the vertical direction as it goes from the opening 30 to the bottom surface 36. And the 1st valve body 62 moves according to the movable direction F1, and makes the 1st non-return valve 6 a closed state. On the other hand, since the movable direction F2 of the second valve body 72 is substantially parallel to the axis O1, the flow path between the second cylinder 70 and the distribution pipe 5 is maintained even when the liquid discharge container 1 is in a horizontal state. There is no blockage. That is, the second check valve 7 is in an open state.

 When the body portion 3 of the container main body 3 is reduced by pressing the body 34 of the liquid discharge container 1 in the horizontal state, the content liquid 90 flows into the second cylinder 70 from the second communication hole 74, From the lower end 50 of the distribution pipe 5, the distribution pipe 5 and the discharge path 40 are sequentially passed through and discharged from the discharge holes 20. At this time, since the first check valve 6 is in the closed state, the air flowing into the first cylinder 60 from the first communication hole 64 communicates the first valve body 62 with the first cylinder 60. It acts so as to press against the connecting portion with the portion 66. The first valve body 62 prevents the air that has flowed into the first cylinder 60 from flowing into the discharge path 40. Thus, the liquid discharge container 1 of the present embodiment prevents the content liquid 90 and air from being mixed in the discharge path 40 and can discharge only the content liquid 90 from the discharge hole 20 in a horizontal state.

  Although the conventional liquid discharge container can discharge the content liquid in either the upright state or the inverted state, the content liquid cannot be discharged in the horizontal state. Such a conventional liquid discharge container will be described with reference to FIGS. In addition, the same code | symbol is attached | subjected to the member same as the discharge container 1 for liquid concerning one Embodiment of this invention, and the description is abbreviate | omitted.

The first cylinder 960 is formed with a first communication hole 64 that communicates the inside of the first cylinder 960 and the inside of the container body 3, and has a shape that decreases in diameter from the opening 30 toward the bottom surface 36. is there. The first cylinder 960 is configured such that the inner diameter of the connection portion with the connecting portion 66 is smaller than the diameter of the first valve body 62.
Further, the movable direction f1 of the first valve body 62 is substantially parallel to the axis O1. That is, the movable direction f1 of the first valve body 62 and the movable direction F2 of the second valve body 72 are substantially parallel.
The second check valve 7 is provided at the distal end of the flow pipe 905 by fitting the lower end 950 of the flow pipe 905 into the upper end opening 76 of the second cylinder 70.

  When the body portion 34 of the liquid discharge container 900 in an upright state is pressed, the content liquid 90 flows into the second cylinder 70 from the second communication hole 74 and enters the distribution pipe 905 from the lower end 950 of the distribution pipe 905. And the discharge path 40 in order, and are discharged from the discharge holes 20. At this time, the first valve body 62 prevents the air that has flowed into the first cylinder 960 from flowing into the discharge path 40. Thus, the liquid discharge container 900 can discharge only the content liquid 90 from the discharge hole 20 in an upright state.

 As shown in FIG. 6, when the liquid discharge container 900 containing the content liquid 90 is turned upside down, the first check valve 906 is opened and the second check valve 7 is closed. .

  When the body 34 of the inverted liquid discharge container 900 is pressed to reduce the volume in the container body 3, the content liquid 90 flows into the first cylinder 960 from the first communication hole 64, The fluid is discharged from the discharge hole 20 through the connecting portion 66 and the discharge path 40 in order. At this time, the second valve body 72 prevents the air that has flowed into the second cylinder 70 from flowing through the flow pipe 5 and into the discharge path 40. Thus, the liquid discharge container 900 can discharge only the content liquid 90 from the discharge hole 20 in an upright state.

  As shown in FIG. 7, when the liquid discharge container 900 containing the content liquid 90 is placed in a horizontal state, the first valve element 62 has a first direction because the movable direction f1 is substantially parallel to the axis O1, that is, substantially horizontal. The check valve 906 cannot be closed. In addition, since the movable direction F2 of the second valve body 72 is substantially parallel to the axis O1, that is, substantially horizontal, the second check valve 7 cannot be closed. That is, in the horizontal state, the first check valve 906 and the second check valve 7 are both opened.

 In the liquid discharge container 900 in a horizontal state, the content liquid 90 and air flow into the first cylinder 960 from the first communication hole 64, and air flows into the second cylinder 70 from the second communication hole 74. As a result, a large amount of air is present in the discharge unit 910. When the body portion 34 of the liquid discharge container 900 is pressed in this state, air preferentially flows into the discharge unit 910 from the first communication hole 64 and the second communication hole 74, so that the air is discharged from the discharge hole 20. The content liquid 90 cannot be ejected preferentially.
