  However, in the above-described conventional technology, there is room for improvement in stabilizing the ejection state such as the size of the droplets of the contents ejected from the nozzle member and the ejection range.

  Then, this invention was made | formed in view of the situation mentioned above, Comprising: The objective is to provide the spray container which can stabilize the ejection state of the content.

In order to solve the above problems, the present invention proposes the following means.
A spray container according to the present invention comprises a stem erected so as to be movable downward in an upward biased state, and a nozzle member attached to the upper end of the stem and having a nozzle hole for ejecting the contents in the container body. And by pressing the nozzle member together with the stem, the container body communicates with the inside of the stem, and the contents in the container body are ejected from the nozzle hole. A cylindrical fixed member is fixed, and a cylindrical movable member is slidably fitted to the fixed member in the container axial direction, and the movable member is pushed into the fixed member. The air between the fixed member and the movable member is pushed out, the air flows into the container body, and between the container body and the fixed member, from the fixed member side to the container body. Allow inflow of air The spray container is provided with a check valve for prohibiting reverse flow, and is disposed between the housing for accommodating the stem so as to be movable up and down, and the stem. Urging means for upwardly urging the upper portion, and a suction cylinder portion whose upper end is opened toward the inside of the housing and whose lower end is immersed in the contents in the container body, and the stem is A lower chamber communicating with the suction cylinder portion and an upper chamber communicating with the nozzle hole are partitioned along a container axial direction, and the lower chamber and the upper chamber are respectively provided in the housing. A lower communication hole and an upper communication hole that can communicate with each other are formed separately, and are fitted on the stem, and the lower communication hole can be opened and closed by expanding and contracting according to the pressure in the container body. A valve having a valve cylinder Comprising a timber, the upper communication hole, with the movement of the container axis of the stem is opened and closed by the check valve, said valve member, said lower communication by the valve cylinder body is expanded The hole is opened .

With such a feature, when the internal pressure of the container body becomes a predetermined value or more, the pressure in the lower chamber acts on the valve cylinder through the lower communication hole, and the valve cylinder is pushed outward in the radial direction. The diameter of the valve cylinder is increased. As a result, the lower communication hole is opened and the lower chamber communicates with the inside of the housing, whereby the contents in the lower chamber circulate downstream through the lower communication hole. Then, by pressing the stem together with the nozzle member while the valve cylinder is open, the upper communication hole closed by the check valve is opened, the housing communicates with the upper chamber, and the contents are transferred to the upper chamber. Flow into. Thereby, the contents are ejected from the nozzle hole.
On the other hand, when the internal pressure of the container body is reduced to less than a predetermined value, the valve body is restored (reduced in diameter), thereby closing the lower communication hole. As a result, the communication between the lower chamber and the inside of the housing is blocked, so that the flow of the contents downstream from the lower chamber is stopped. Therefore, even if the stem is operated together with the nozzle member, the contents are not ejected.
Thus, since ejection can be permitted or stopped according to the pressure in the container body, the ejection state of the contents can be stabilized. That is, since ejection is permitted only when the valve cylinder is in the open state, droplets (contents) can be ejected in a suitable spray state at a certain pressure or higher.

  In the spray container of the present invention, the valve member and the urging means may be integrally formed.

  In this case, by forming the valve member integrally with the urging means, the number of parts can be reduced and the cost can be reduced.

  According to the spray container according to the present invention, the ejection state of the contents can be stabilized.

Has been. Therefore, the biasing means 83 is configured to be elastically deformable between the bottom portion 82 and the housing 24 as the stem 22 and the valve member 25 move up and down. The urging means 83 is formed over the entire circumference of the bottom portion 82, and is in close contact with the connecting portion between the upper peripheral edge of the rib 80 and the surrounding cylinder portion 75, with respect to the urging means 83. The inside and outside are sealed.

Next, the effect | action of the spray container 1 mentioned above is demonstrated.
First, as shown in FIGS. 1 and 2, air is supplied into the container body 2 by moving the sliding cylinder 45 of the movable member 32 up and down between the outer cylinder 33 and the inner cylinder 34 of the fixed member 31. The internal pressure of the container body 2 is increased.
Specifically, in a state where the sliding cylinder 45 of the movable member 32 is inserted between the outer cylinder 33 and the inner cylinder 34, the sliding cylinder 45 is pushed downward, and the fixed member 31 and the movable member 32 The enclosed cylinder space S1 (the space below the flange portion 47 of the sliding cylinder 45, the space between the sliding cylinder 45 and the inner cylinder 34, and the space between the sliding cylinder 45 and the nozzle member 23) ). Then, the pressure in the cylinder space S <b> 1 acts on the check valve 101 through the through hole 42 formed in the inner flange portion 41 of the fixing member 31. Thereby, the check valve 101 is opened by the outer peripheral side of the check valve 101 being bent downward and deformed. It should be noted that, even though the outer circumferential surface of the inner cylinder 34 extends over the entire length in the vertical direction, a plurality of vertical grooves are formed along the circumferential direction, and a part of the sliding cylinder 45 is in sliding contact with the outer circumferential surface of the inner cylinder 34. Good.

  When the check valve 101 is opened, the cylinder space S1 and the container body 2 communicate with each other, and air flows from the cylinder space S1 into the air flow path R1. The air flowing into the air flow path R <b> 1 passes through the communication groove 81 of the housing 24, and then passes between the surrounding cylinder portion 75 of the housing 24 and the inner cylinder 34 of the fixing member 31 and is supplied into the container body 2. The Part of the air that has flowed into the air flow path R <b> 1 flows through the groove 78 of the housing 24 toward the inside in the radial direction, and is also supplied to the storage space S <b> 2 between the stem 22 and the housing 24. The The air supplied to the storage space S <b> 2 is blocked from flowing into the upper chamber 63 by the stem 22 and the check valve 101.

Further, when the sliding cylinder 45 of the movable member 32 is pushed down to the lower end position and the pressing operation of the sliding cylinder 45 is stopped, the pressurization of the cylinder space S1 by the sliding cylinder 45 is stopped, and the check valve 101 is restored and deformed. As a result, the check valve 101 is closed.
Thereafter, when the sliding cylinder 45 of the movable member 32 is pulled up, the cylinder space S1 becomes negative pressure, and the slit 48 of the sliding cylinder 45 is opened by this negative pressure. Then, outside air flows in through the slit 48, and the cylinder space S1 rises to atmospheric pressure.
And by repeating the up-and-down movement of the movable member 32, air is supplied into the container main body 2 by the piston movement by the cooperation of the fixed member 31 and the movable member 32, and the internal pressure of the container main body 2 is increased. it can.

Here, when the internal pressure of the container main body 2 increases, the contents in the container main body 2 reach the inner space of the biasing means 83 through the suction cylinder portion 26 and then the through hole 84 of the bottom portion 82 in the valve member 25. And flows into the lower chamber 62.
As shown in FIG. 3, when the internal pressure of the container body 2 further increases and exceeds a predetermined value, the pressure in the lower chamber 62 acts on the valve cylinder 68 through the lower communication hole 67, and the valve cylinder 68 Is expanded outward in the radial direction, so that the valve body 68 is expanded. As a result, the lower communication hole 67 is opened and the inside and outside of the lower chamber 62 communicate with each other, so that the contents in the lower chamber 62 are supplied into the storage space S2 through the lower communication hole 67 (see FIG. (See arrow Y1 in 3). The contents supplied to the storage space S <b> 2 are blocked from flowing to the upper chamber 63 side by the stem 22 and the check valve 101.

  Next, when the contents are ejected from the spray container 1, the movable member 32 is first lifted and removed from the fixed member 31, and the nozzle member 23 is pressed down. When the nozzle member 23 is pressed, the stem 22 and the valve member 25 move downward together with the nozzle member 23. At this time, when the upper communication hole 66 formed in the upper chamber 63 of the stem 22 moves below the check valve 101 in the vertical direction, it is opened toward the storage space S2, and the upper chamber 63 and the storage space S2 Communicate. Then, the content and air blocked by the check valve 101 and the stem 22 flow into the upper chamber 63 of the stem 22 through the upper communication hole 66 (see arrow Y2 in FIG. 3). Thereafter, the contents flowing into the stem 22 pass through the mounting cylinder 73 of the nozzle member 23 and are then ejected from the nozzle hole 23a together with air. Thereby, a droplet is ejected with the suitable spray form.

By the way, in the spray container 1 of this embodiment, air is discharged | emitted from the container main body 2 with the content by repeating ejection, and the internal pressure of the container main body 2 falls.
Here, in the present embodiment, when the internal pressure of the container main body 2 decreases to less than a predetermined value, the valve cylinder 68 is restored (reduced in diameter), so that the valve cylinder 68 comes into close contact with the stem 22 again. As a result, the lower communication hole 67 is closed, and the flow of contents between the lower chamber 62 and the storage space S2 is blocked. Therefore, even if the nozzle member 23 is operated in this state and the inside of the stem 22 (upper chamber 63) communicates with the inside of the housing 24, the contents are not ejected. In addition, in order to eject the contents again, the movable member 32 is attached to the fixed member 31 and the internal pressure of the container body 2 is increased to a predetermined value or more, so that the contents are ejected by the same action as described above. be able to.

As described above, in the present embodiment, the stem 22 is divided into the lower chamber 62 and the upper chamber 63, and the lower chamber 62 can be opened and closed by the valve body 68 according to the pressure in the container body 2. The upper chamber 63 can be opened and closed as it moves up and down.
According to this configuration, when the internal pressure of the container body 2 is equal to or greater than a predetermined value, the lower communication hole 67 is opened to allow the content to flow downstream from the lower chamber 62. In this case, when the lower communication hole 67 is opened, the stem 22 is pressed together with the nozzle member 23 to open the upper communication hole 66 of the upper chamber 63 so that the contents flow into the upper chamber 63. The contents are ejected from the nozzle hole 23a.
On the other hand, when the internal pressure of the container body 2 falls below a predetermined value, the lower communication hole 67 can be closed to stop the flow of the contents downstream from the lower chamber 62. In this case, even if the stem 22 is pressed together with the nozzle member 23, the content does not flow into the upper chamber 63, so that the content is not ejected from the nozzle hole 23a.

  Therefore, since the ejection of the contents can be allowed or stopped according to the pressure in the container body 2, the ejection state of the contents can be stabilized. That is, since ejection is permitted only when the valve cylinder 68 is in the valve open state, it is possible to eject droplets (contents) in a suitable spraying state at a certain pressure or higher.

  In the present embodiment, the valve body 68 and the biasing means 83 are integrally formed, so that the number of parts can be reduced and the cost can be reduced.

As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the concrete structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
For example, the valve body 68 and the biasing means 83 (which may be an elastic member such as a coil spring) may be formed separately.
Further, in the above-described embodiment, the configuration in which the groove portion 78 is formed in the upper end edge of the main body cylinder portion 61 in the housing 24 has been described. A through hole may be formed.
According to this configuration, the upper end edge of the main body cylinder portion 61 and the check valve 101 can be uniformly contacted over the entire circumference, so that the durability of the check valve 101 can be improved and the circulation is inhibited. No longer occurs.

  In addition, in the range which does not deviate from the meaning of this invention, it is possible to replace suitably the component in the embodiment mentioned above by the known component, and you may combine the modification mentioned above suitably.
