Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a container for releasing an aromatic agent such as a liquid insecticide into the atmosphere.

[Conventional technology]

A container in which a liquid fragrance is contained in a container and which is made to diffuse into the atmosphere by a suction member inserted into the container mouth is, for example, Shoujo 61-339 shown in FIG.
There is a liquid fragrance spreading container described in Japanese Patent No. 57. That is, a liquid fragrance is contained in the container 1. A sleeve 3 is fitted and inserted on the inner peripheral side of the mouth end portion 2 of the container 1, and a suction member 5 is fitted and held inside the sleeve 3. Further, the sleeve 3 is formed with some vertical slits 4 on the contact surface with the suction member 5, and the vertical slits 4 are communicated with the atmosphere inside and outside the container 1. With this structure, the fragrance in the container 1 is sucked up by the suction member 5 and is diffused into the atmosphere.

Further, the following action is obtained by providing the vertical slit 4. That is, when the temperature inside the installed room or inside the vehicle is higher than the internal temperature of the container 1,
When the internal air of the container 1 expands, aromatics are pushed up by the internal pressure of the container 1 and ejected, which continues until the pressure difference between the inside and outside of the container 1 disappears.
Therefore, this problem is solved by discharging the expanded air in the container 1 from the vertical slit 4 until the pressure difference between the inside and the outside disappears, thereby avoiding the above-mentioned waste due to the spouting of the fragrance.

[Problems to be solved by the device]

However, in the case of the liquid fragrance spreading container of FIG. 3, the problem that the fragrance leaks to the outside of the container through the vertical slits 4 when the container 1 falls over sideways during storage has not been solved.

The present invention has been made in view of the above matters, and at the same time, it is possible to eliminate the problem that the aromatic agent is unnecessarily discharged due to the pressure difference between the inside and the outside of the container, and at the same time, the aromatic agent does not leak to the outside due to sideways collapse during storage in the container, In particular, it is a technical object to provide a liquid aroma container suitable for an insecticide / aromatic agent container in which an aroma liquid causes unexpected damage by leaking out of the container like an insecticide.

[Means for Solving the Problems]

In the liquid aroma container according to the present invention, a sleeve-shaped air bleeding adjustment member 30 made of synthetic resin is fitted into the mouth end 11 of the container body 10, and a porous body fitted to the inner peripheral surface of the air bleeding adjustment member 30. A divergent member that is made of a material that can absorb liquid by capillary action
The liquid in the container body 10 is made to diffuse to the atmosphere by 40, and the first and second concave grooves 32, 33 are provided in close proximity to the inner peripheral surface of the air bleeding adjustment member 30, 32 has an opening end 32a communicating with the inside of the container body 10 at one end and a closing end 32b at the other end, and the second groove 33 has an opening end 33a for opening to the atmosphere at one end and the other end. The closed end 33b is provided in the vicinity of the closed end 32b of the first groove 32, and the closed end 32b of the first groove 32 and the second groove 3 due to the fluctuation of the internal pressure of the container body 10.
The closed end 32b of 3 is connected to and communicates with the inside of the container body 10 to the atmosphere.

[Action]

At the time of use, the cap 20 closing the mouth end 11 of the container body 10 is removed. Since the first and second recessed grooves 32, 33 provided in the air bleeding adjustment member 30 can be set to be in a communicating state or a blocking state with each other in accordance with the pressure difference between the inside and the outside of the container, the average temperature is flat. In a warm environment, the divergent member causes a calm divergence.

Further, when the pressure difference between the inside and the outside of the container becomes large, the first groove 32 and the second groove 33 are in communication with each other, so by letting the air inside the container escape to the atmosphere, the internal pressure due to the expansion of the container body 10 The liquid does not squirt through the divergent member when the pressure rises. That is, unnecessary divergence of liquid is prevented.

Further, even if the container body 10 falls sideways during divergence, the first concave groove 32 and the second concave groove 33 are always blocked, so that no liquid leaks out from here.

〔Example〕

Hereinafter, an embodiment of the liquid diffusion container according to the present invention will be described with reference to FIGS. 1 to 9.

As shown in FIGS. 1 to 5, a cap 20 is screwed on and closed at the mouth end 11 of the container body 10 containing a liquid such as an insecticide. A screw 12 with which a cap 20 is screwed is formed on an outer peripheral surface of the mouth end portion 11, and a locking end portion 13 into which a sleeve-shaped air bleeding adjustment member 30 is fitted is formed on a peripheral edge of a tip end.
The air bleeding adjustment member 30 is formed from a cylindrical inner peripheral wall portion 31, an intermediate peripheral wall portion 34 and an outer peripheral wall portion 35 in this order from the center to the outside, and the mouth end portion 11 is provided between the intermediate peripheral wall portion 34 and the outer peripheral wall portion 35. It is fitted in a gas-liquid-tight manner on the side locking end portion 13 by undercut fitting. Around the middle peripheral wall portion 34 and the outer peripheral wall portion 35, an annular lip 37 for ensuring a sealing property with the mouth end portion 13,
An annular lip 37 that ensures a tight seal with the cap 20
Are molded respectively.

Further, on the inner peripheral surface of the inner peripheral wall portion 31, a divergent member 40 formed of a rod-shaped porous body and capable of sucking up the liquid by a capillary phenomenon is fitted. This diverging member 40 is submerged in the liquid in the container body 10,
In addition, the upper tip of the figure has a length that projects outside the container. That is, the wicking action of the divergent member 40 diverges the liquid into the atmosphere to diffuse the fragrance or drug. The contact surface between the inner peripheral wall portion 31 and the diverging member 40 is configured as follows.

That is, as is apparent from the drawings starting from FIG. 2, the first and second recessed grooves 32, 33 are brought close to the inner peripheral surface of the inner peripheral wall portion 31 of the air bleeding adjusting member 30 in the axial direction in the vertical direction of the drawing. Is provided. The first groove 32 is provided in a pair (see FIG. 4) facing each other in the radial direction of the inner circumference, and has a length a in the vertical direction. One lower end in the figure is an open end 32a communicating with the inside of the container body 10, and the other upper end in the figure is a closed end 32b. Further, in the case of the second groove 33, as shown in FIGS. 2 and 5,
At a position very close to the above-mentioned first concave groove 32, a pair of opposed inner radial directions are provided. One end on the upper side of the figure is an open end 33a open to the atmosphere, and the other end on the lower side of the figure is a closed end 33b adjacent to and adjacent to the closed end 32b of the first groove 32, which is a vertical direction. Has a length b.

Next, the operation of the diffusion container of the embodiment having the above configuration will be described.

In use, the cap 20 is removed from the mouth end 11 of the container body 10. Under an environment where the internal pressure of the container body 10 and the external atmospheric pressure are equilibrated under the condition where the temperature is averaged,
The liquid insecticide in 10 is sucked up through the spreading member 40,
It is emitted into the atmosphere and is fragrant. At this time, the first and second recessed grooves 32, 33 in the air bleeding adjustment member 30 are in a position in which they are close to each other but are in an intermittent state. Therefore, the liquid insecticide does not pass through the both concave grooves 32, 33, and the airtightness between the inner peripheral wall portion 31 and the divergent member 40 is secured.

On the other hand, when the temperature outside the container body 10 rises and the temperature difference between the inside and outside increases, the container body 10 expands and the internal pressure rises. Then, this pressure causes the closed ends 32b and 33b of the first and second concave grooves 32 and 33 to come into contact with each other, and the first concave groove 32 and the second concave groove 33.
Communicate with each other. That is, the inside of the container body 10 communicates with the outside through these. By this atmospheric release, the internal air of the container body 10 escapes, and the internal and external pressures are balanced. By this action, the liquid pesticide is sucked up from the diverging member 40 in a jetted state due to the increase in the internal pressure in the container body 10, and unnecessary divergent discharge is avoided.

[Effect of device]

As described above, the liquid diverging container according to the present invention has the first and second concave grooves 32, 33 provided in the air bleeding adjustment member 30.
However, since they can be set in a communicating state or a shut-off state in correspondence with the pressure difference between the inside and the outside of the container, calm divergence is performed by the diverging member in a normal temperature environment where the temperature is average. Also, when the pressure difference between the inside and outside of the container increases,
Since the first groove 32 and the second groove 33 are in communication with each other,
By letting the air inside the container escape to the atmosphere from here, the container body
Unnecessary divergence, such as the liquid being jetted through the divergent member due to the increase in internal pressure due to the expansion of 10, is prevented.

From such an action, during divergence, even if the container body 10 falls over sideways, the liquid in the container does not leak out from the concave groove like the conventional container of this type, and as a liquid aroma container such as an insecticide. Optimal.
