Abstract

PURPOSE:To control a gas discharge quantity from a discharge port by adjusting the contracting quantity of a flow rate controlling valve by relatively turning a container main body and a lid body. CONSTITUTION:In a main body 2 of a container 1, an aromatizing agent 12, which is a liquid or solid, etc., is stored. Under a condition where a cylindrical shaped thin film 6 gives a normal cylindrical shape without any deformation, as a flow rate controlling valve 5, it is under the totally opened condition, and a volatile gas from the aromatizing agent 12, i.e., the fragrance is gradually discharged to the outside of the container, e.g., the interior of an automobile, etc., through a discharge port 4. ln this case, by turning a lid body 3, the cylindrical shaped thin film 6 can be deformed, and the flow rate controlling valve 5 can be totally closed or the inner diameter can be continuously changed without steps. Thus, the fragrance discharge quantity from the aromatizing agent 12 can be freely controlled.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a container used as an air freshener, a deodorizer, or a deodorizer placed, for example, indoors in buildings, automobiles, and the like.

<Prior Art> Conventionally, there have been known air fresheners, deodorizers, etc. in which a continuous liquid or solid fragrance is stored in a sealed container such as a bottle, and when used, the outlet is opened to release the fragrance. It is being

<Problems to be Solved by the Invention> However, in such conventional aroma devices, the opening area of the discharge port is constant, and the amount of aroma emitted from the discharge port is fixed to a constant amount. .

In addition, there are some devices in which a sliding shutter is provided at the discharge port to adjust the discharge amount, but in many cases, the airtightness of the moving and rotating parts is insufficient. Furthermore, the airtightness deteriorated due to wear during use.

For this reason, the amount of fragrance emitted may not be able to be opened, and the fragrance may be released excessively into the room, or the fragrance may leak even when not in use.
The indoor space, which should be comfortable, can instead become a place of disgust.

In view of the above-mentioned conventional circumstances, the present invention provides a container that uses a simple structure but highly airtight flow rate control mechanism to freely and reliably adjust the amount of gas released from the inside. 17.

<Means for Solving the Problems> For this reason, the present invention provides a container main body having an open top portion;
A lid body is rotatably assembled to the container body so as to cover the opening part, and has a plurality of discharge holes in its end plate, and an interior formed by the container body and the lid body. It consists of a flexible and elastic cylindrical thin film material arranged in a space, the periphery of the opening at one end is hermetically fixed to the inner wall of the container body, and the periphery of the opening at the other end is fixed to the lid. a flow rate control valve airtightly fixed to the inner wall of the body, and by relatively rotating the container body and the lid body to adjust the aperture of the flow rate control valve, gas can be discharged from the discharge hole. A container that controls the amount released. ”.

In this configuration, when the cylindrical thin film is in a normal cylindrical shape without undergoing any deformation, the flow rate control valve is fully open, and the gas inside the container is released outside the container through the discharge hole. is gradually released.

Then, when the lid is rotated in either the forward or reverse direction, the cylindrical thin film moves against the periphery of the lower end opening fixed to the container body.
Since the periphery of the upper opening fixed to the lid body rotates relatively,
The intermediate body of the cylindrical thin film is constricted to have a small diameter.

The amount of narrowing of the intermediate barrel is approximately proportional to the rotation angle of the lid, that is, the rotation angle of the upper end opening periphery, and the inner diameter of the cylindrical thin film decreases steplessly. In this case, the amount of contraction of the intermediate body portion of the cylindrical thin film can be increased until the inner diameter of the film is finally zero, that is, the film is fully opened.

Therefore, the amount of gas passing through the inner diameter portion of the cylindrical thin +1W film is regulated in an airtight state, and the amount of gas released can be freely controlled.

<Example> Next, embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, ``■'' is a cylindrical container for an air freshener, which includes a container main body 2 with an open top surface, and a container main body 2 that is freely rotatable in the circumferential direction so as to cover the top open portion 2a of the container main body 2, and that can be freely rotated at least freely. The lid body 3 is assembled so that it can be locked in position.

4 is a large number of discharge holes on the upper wall of the end plate of the lid body 3;
Reference numeral 5 denotes a flow control valve disposed in a space formed by the container body 2 and the lid 3, and the peripheral edge of the opening at one end is connected to the container body 2.
A flexible and highly elastic cylindrical thin film 6 made of, for example, a Latinx rubber film, is hermetically fixed to the inner peripheral wall of the lid body 3 and the peripheral edge of the opening at the other end is hermetically fixed to the inner peripheral wall of the lid body 3, respectively.
The inner diameter portion of the film 6 is formed to be able to expand and contract in substantially proportion to the rotation of the lid 3.

Here, the container main body 2 is a bottomed cylindrical lower structure 2.
It consists of an assembled body of A and a cylindrical upper structure 2B with upper and lower openings. In this case, the male threaded portion 2b of the upper structure 2B is airtightly fitted into the female threaded portion 2b of the lower structure 2A, and both horizontal bodies 2A; 2B are removably assembled.

Further, an annular groove 7 substantially parallel to the opening surface is formed on the outer circumferential surface of the upper end of the container body 2.

An annular groove 8 parallel to the opening edge of the lower end of the lid body 3 is also formed on the inner peripheral surface of the opening edge.

The container main body 2 and the lid 3 are connected to the annular 't' of the container main body 2.
The lower edge of the lid 3 is inserted into the annular groove 8 of the lid 3.
The container body 2 is assembled by fitting the upper end edges of the container body 2 to the container body 2, respectively.

This fitted state is such that the lid 3 and the container body 2 are relatively free to rotate and can be locked at any rotational position by the force of rubbing at the fitting portion in the annular groove. There is.

Ear portions 9 each having a circular cross section are formed at the peripheries of the openings at both ends of the cylindrical thin 11-tuff film constituting the flow rate control valve 5 .

As shown in FIG. 2, the portions near the ears 9 at both ends of the cylindrical thin film 6 are connected to the inner surface of the container body 2 and the lid 3, respectively.
curved and fitted into the annular groove lO formed on the inner surface of the
Furthermore, the C-ring 11 is press-fitted into the annular groove 10, and the C-ring 11 is airtightly fixed. In this case, since the ears 9 are formed, even if a tensile force is applied to the cylindrical thin film 6ζ, the film 6 will not fall off from the IQ shape ii410.

In the main body 2 of the container 1, a liquid or solid aromatic agent 12 is stored.

The operation of the aroma device having such a configuration will be explained.

When the cylindrical thin film 6 is in a normal cylindrical shape without any deformation, the flow rate control valve 5 is fully open, and the volatile gas from the aromatic agent 12, that is, the aroma, is released through the discharge hole 4. It is gradually released outside the container, for example into the interior of a car.

By rotating the lid 3, the cylindrical thin film 6 is deformed as follows, and the flow rate control valve 5 is fully closed, or the inner diameter is changed steplessly and continuously. The amount of fragrance emitted from the aromatic agent 12 can be adjusted arbitrarily eight times.

That is, when the lid 3 is rotated, the cylindrical thin film 6 is rotated around the lower end opening fixed to the container body 2 and around the upper end opening fixed to the lid 3, as shown in FIG. As such, the intermediate body portion of the cylindrical thin film 6 is narrowed down. Therefore, the aperture star of the intermediate body of the cylindrical thin film 6 is approximately proportional to the rotation angle of the lid 3, that is, the rotation angle of the upper O; ii opening circumference i, and the inner diameter of the intermediate body. shrinks and changes by 1. In this case, when the intermediate body is completely squeezed, the inner diameter of the film 6 becomes O, that is,
Fully open state [yotonaru] At this time, since the center of the film 6 is in close contact with each other under tension, a large airtightness is maintained.

Therefore, the amount of fragrance passing through the inside of the cylindrical thin film 6 is regulated.

In addition, as shown in FIG. 4, a mark 13 is provided on the outer peripheral surface of the container body 2, and a scale 14 is provided on the lid body 3.
It may also be provided so that the amount of contraction of the container body 2 due to the rotation f)+ is displayed.

According to this configuration, the fragrance emitted from the discharge hole 11 of the lid body 3 can be adjusted as desired.

To prevent fragrance from being excessively diffused into a room, and to make the indoor space comfortable at all times.

In this embodiment, the lid body 3 is provided in a fitted state in which it can freely rotate relative to the container body 2 and can be locked at any rotational position by the frictional force on the fitting surface, and the flow rate control valve is Although the opening degree of the lid body 3 is changed continuously, the opening degree of the lid body 3
By interposing a ratchet mechanism or the like between the container body 2 and the container body 2, the opening degree of the flow control valve 5 can be adjusted in stages by creating a fitted state in which rotation is free and reverse rotation can be prevented at a predetermined rotation position. It may be changed to .

In addition, in this embodiment, the container 1 used for the aroma device
Although described above, it can also be applied to other containers for the purpose of releasing other gases.

<Effects of the Invention> As explained above, according to the container of the present invention, by adopting a simple flow control mechanism using a flexible and highly elastic cylindrical thin film, the amount of gas released from the inside can be controlled by 8 cycles. Because it can be closed and maintain airtightness when closed, for example, containers used in air fresheners, deodorizers, and deodorizers will not release scents or chemicals excessively into the room.
, it is possible to enjoy any desired aroma and provide a moderate deodorizing effect, so it has the effect of making the indoor space comfortable at all times.
