A check valve for introducing outside air, which blocks the inflow of outside air into the inside of the container body and allows the outside air to flow into the inside of the container body when the inside pressure of the container body becomes negative, and is upright even in an inverted state. Even in the state, a suction pipe device for sucking the liquid substance in the container body is arranged, and further, the check valve for introducing the outside air is provided with a cover so that the liquid pressure in the container body is not directly applied. The above object is achieved by providing a characteristic spray container.

[0007] The invention described in claim 2 of the present invention provides
The spray container according to claim 1, wherein the suction pipe device is mounted on the intake and supplies a liquid substance into the vertical pipe line, and a liquid supply reverse pipe interposed in an intermediate portion of the pipe. The check valve for liquid supply, which is composed of a stop valve, allows the liquid material to be sucked from the tip of the pipe in the upright state of the spray container, and the tip of the pipe when the spray container is inverted. There is provided a spray container characterized in that the liquid substance is blocked from flowing into the vertical pipe passage from the mouth side of the container body.

[0008] The invention described in claim 3 of the present invention provides:
The spray container according to claim 1, wherein the suction pipe device is a pipe that is attached to the intake and supplies a liquid substance into the vertical conduit, and the pipe has a bendable bellows portion. The present invention provides a spray container having an anchor at its tip.

In the spray container according to any one of claims 1 to 3 of the present invention, when the spray container is in the upright state, the check valve for introducing outside air does not block the inflow of outside air, and the trigger is used. When the inside of the container body is operated to have a negative pressure, outside air flows into the container body, and deformation of the container body is suppressed. When the spray container is in an inverted state, the check valve for introducing the outside air blocks the inflow of outside air, and the cover prevents the check valve for introducing the outside air from being directly applied with the hydraulic pressure in the container body. Therefore, leakage of the liquid material in this state is reliably suppressed. When the trigger is operated in this state, the liquid substance in the container body is supplied to the vertical conduit through the suction pipe device. When the pressure inside the container body becomes negative due to the operation of the trigger, the check valve for introducing outside air is opened and the outside air flows into the container body, so that the deformation of the container body is suppressed. The cover has an inner diameter of 0.1 m
Providing pores with a diameter of m to 0.8 mm, preferably 0.3 to 0.5 mm is effective for surely preventing leakage of the liquid substance and allowing the outside air to flow into the container body.

In the spray container A of the first embodiment, the liquid supply check valve 14 of the suction pipe device 27 is used.
The internal volume V (see FIG. 1) is set to be larger than the ejection amount of the liquid material (volume of the cylinder S) by one operation of the trigger 7, and thereby stable ejection is possible.

When the spray container A is in the upright state, as shown in FIG. 1, the check valve 13 for introducing outside air does not block the inflow of outside air through the outside air introducing holes 6a, 10a, and The check valves 14a and 14b are closed. When the trigger 7 is operated in this state, the piston / cylinder mechanism 12 is actuated, and the inside of the vertical pipe line 5 gradually becomes negative pressure, and the ball valve element 2 of the check valve 14a.
6a moves upward, and the liquid substance is sucked from the lower end portion of the pipe 11 and supplied to the pipe portion 10d of the intake 10 (arrow X in the figure). When the trigger 7 is further operated, the vertical conduit 5, the horizontal conduit 4, and the spin element 8 are
Also, the liquid material is ejected to the outside through the nozzle member 9. With the operation of the trigger 7, the piston member 1
When the sliding portion 15a of 5 moves rearward from the outside air introduction hole 6a, outside air flows into the container body 2 through the outside air introduction holes 6a and 10a, so that the deformation of the container body 2 is suppressed.

When the spray container A is upside down, as shown in FIG. 3, the container body 2 is passed through the outside air introduction holes 6a and 10a by the outside air introduction check valve 13 as shown in FIG.
The inflow of outside air into the inside is blocked, and the cover 13a prevents the check valve 13 for introducing outside air from being directly applied with the hydraulic pressure in the container body 2. Therefore, in this inverted state, leakage of the liquid substance from the outside air introduction hole 10a is reliably suppressed. Further, in this state, the check valves 14a and 14b are closed.

When the trigger 7 is operated in this state,
The piston / cylinder mechanism 12 operates, the inside of the vertical conduit 5 becomes negative pressure, the ball valve body 25a of the check valve 14b opens, and the liquid material is sucked from the tubular member 25 to cause intake of the intake 10. It is supplied to the pipe portion 10d (arrow Y in the figure). When the trigger is further operated, the liquid substance is ejected to the outside through the vertical pipe line 5, the horizontal pipe line 4, the spin element 8, and the nozzle member 9. When the sliding portion 15a of the piston member 15 moves rearward from the outside air introducing hole 6a in accordance with the operation of the trigger 7, the ball valve element 19b of the check valve 13 for introducing outside air opens to open the outside air introducing hole 6a. Since the outside air flows into the container body 2 through 10a, the deformation of the container body 2 is suppressed. Further, at this time, the space between the ball valve element 19b and the outside air introduction hole 10a in the outside air check valve 13 is opened only to the extent that outside air can flow in due to the negative pressure inside the container body 2. The leakage of the liquid material through the outside air introduction holes 6a and 10a can be surely suppressed.

As described above, according to the spray container A, the liquid material filled in the container body 2 can be suitably ejected regardless of whether the spray container A is upright or inverted.

Further, since the cover 13a is fitted to the outside air introduction check valve 13 so that the hydraulic pressure in the container body 2 does not directly act on the outside air introduction check valve, the container body 2 is in an inverted state. It is possible to more reliably suppress the leakage of the liquid material when the above is set.

Further, since the valve body of the check valve 13 for introducing the outside air is the ball valve body 19b, when the spray container A is in the upright state, the inflow of the outside air is not blocked, and when the spray container A is in the upright state, the outside air is blocked. A mechanism for blocking the inflow can be easily manufactured.

FIGS. 4 and 5 show a second embodiment of the spray container according to the present invention. In these figures, the symbol B indicates a spray container.

The spray container B has a suction pipe device 27 'in place of the pipe device 27 of the spray container A of the first embodiment, except that the spray container B has a suction pipe device 27'.
Since it has the same configuration as the spray container A of the embodiment, the characteristic part thereof will be described in the following description, and the parts common to the spray container A of the first embodiment will be denoted by the same reference numerals, The description is omitted.

The suction pipe device 27 'in the spray container B has the pipe portions 10d, 10e of the intake 10.
The pipe 31 has a bendable bellows portion 32 and a spherical anchor 33 attached to the tip end portion 31a. Then, the tip portion 31 of the pipe 31 is held regardless of whether the spray container C is upright or upside down.
The liquid a can always be immersed in the liquid substance in the container body 2. The tip portion 31a of the pipe 31 has the anchor 3
It is provided in a shell shape corresponding to 3. Further, a predetermined space is provided between the anchor 33 and the inner surface of the distal end opening so that the liquid material can be sucked smoothly.

In the upright state of the spray container B of the second embodiment, as shown in FIG. 4, the check valve 13 for introducing the outside air blocks the inflow of outside air through the outside air introducing hole 6a. In addition, the tip portion 3 of the pipe 31
1a is directed downward by the anchor 33. When the trigger 7 is operated in this state, the piston / cylinder mechanism 12 is activated, and the inside of the vertical pipe line 5 gradually becomes a negative pressure, and the liquid substance is sucked from the tip portion 31a of the pipe 31, and the pipe of the intake pipe 10 is taken. It is supplied to the portion 10d (arrow X in the figure). When the trigger 7 is further operated, the liquid substance is ejected to the outside through the vertical pipe line 5, the horizontal pipe line 4, the spin element 8 and the nozzle member 9. With the operation of the trigger 7, the piston member 1
When the sliding portion 15a of 5 moves rearward from the outside air introduction hole 6a, outside air flows into the container body 2 through the outside air introduction holes 6a and 10a, so that the deformation of the container body 2 is suppressed.

When the spray container B is in an inverted state, as shown in FIG. 5, the ball valve element 19b of the check valve 13 for introducing the outside air blocks the outside air introducing hole 10a, and the outside air is introduced by the cover 13a. Since the check valve is not directly applied with the liquid pressure in the container body 2, the leakage of the liquid substance from the outside air introduction hole 10a is surely suppressed, and the container body 2 through the outside air introduction holes 6a and 10a is surely suppressed. The inflow of outside air into the inside is surely blocked. Further, since the bellows portion 32 bends due to the weight of the anchor 33, the tip portion 31a of the pipe 31 is immersed in the liquid substance on the mouth side of the container body 2.

When the trigger 7 is operated in this state,
The piston / cylinder mechanism 12 operates, and the inside of the vertical pipe line 5 becomes a negative pressure, and the tip portion 31a of the pipe 31.
The liquid substance is sucked from and is supplied to the pipe portion 10d of the intake 10 (arrow Y in the figure). When the trigger is further operated, the liquid substance is ejected to the outside through the vertical pipe line 5, the horizontal pipe line 4, the spin element 8, and the nozzle member 9. As the trigger 7 is operated, the sliding portion 15a of the piston member 15 causes the outside air introduction hole 6a to move.
When moving further rearward, the ball valve body 19b of the check valve 13 for introducing the outside air opens, and the outside air flows into the container body 2 through the outside air introducing holes 6a and 10a, so that the deformation of the container body 2 is suppressed. At this time, the check valve 1 for introducing the outside air
3 between the ball valve body 19b and the outside air introduction hole 10a is opened only to the extent that the outside air can flow in due to the negative pressure in the container body 2, so that the outside air introduction hole 6a is combined with the effect of the cover. No liquid will leak through.

According to the spray container B of the present embodiment, like the spray container A of the first embodiment described above, the liquid material filled in the container body 2 can be suitably ejected in the upright state or the inverted state. You can In the spray container B,
Since the suction pipe device 27 'is composed of the pipe 31, the sprayer 3 can be mounted without any trouble even when the mouth of the container body 2 is small.

The spray container according to the present invention is not limited to the spray container of each of the above-mentioned embodiments, and its size, shape and the like can be appropriately changed without departing from the object of the present invention.

For example, instead of the cover 13a in the spray container A or B of each of the above-mentioned embodiments, a cover 13a of the form shown in FIGS. 6 (a) to 6 (d) is used as a cover provided in the check valve for introducing outside air. 'May be adopted.
