Abstract

PURPOSE:To constitute a push button for an aerosol container employable for multiple purpose, by providing an introduction chamber having an outside insertion port in the main body of the push button, and by switching the communications with a stem and a nozzle and with the insertion port by a sliding valve. CONSTITUTION:In the main body 5 of a push button, an introduction chamber 7 communicated with a stem 4 and a nozzle 8 and having an outside insertion port 12 is provided, and a sliding valve 10 pressed by a spring 11 so as to close the outside insertion port 12 is inserted slidably into said introduction chamber 7. On the occasion of ordinary employment, the stem 4 is communicated with the nozzle 8 through the introduction chamber 7, and when the content is packed in the container 1, the sliding valve 10 is pressed to slide from the outside insertion port 12. Such a constitution enables re-packing of the content and the employment of the push button for multiple purpose.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a push button for an aerosol container, and although there have been various types of push buttons for aerosol containers in the past, all of them are only capable of spraying the contents inside the aerosol container. However, there has never been an aerosol container that allows refilling, pressure filling, etc. of the contents in the aerosol container, or connects various other adapters to enable multipurpose use.

The present invention relates to a push button for an aerosol container that can be used for multiple purposes as described above, and includes an introduction chamber in the push button body having a stem fixed to one end, which communicates with the stem and the nozzle, and has an external insertion port. A slide valve that is pressed by a spring to close the external insertion port is slidably inserted into the introduction chamber, and when this slide valve is pressed from the direction of the external insertion port, communication between the nozzle and the stem is cut off. At the same time, the external insertion port and the stem are in communication, and during normal use, the stem and nozzle are communicated through the introduction chamber, and the external insertion port is closed with a sliding valve to inject the aerosol contents. When using refill filling, pressure filling, or other appropriate adapters connected to the push button body,
By inserting the refilling stem, adapter communication pipe, etc. from the external insertion port and pressing and sliding the slide valve, the stem is communicated with the refilling stem, adapter communication pipe, etc. via the introduction chamber. It enables multi-purpose use. An embodiment of the present invention will be described below with reference to the drawings. (1) is a conventionally known aerosol container, and a mountain cup (3) is provided through an eyelet (2).
A stem (4) protrudes from the center of the holder. (5) is a push button body, which has an introduction chamber (7) formed inside through a communication port (6) that communicates with the stem (4), and has a nozzle (8) formed on one side. ) and the introduction chamber (7) are communicated through a connection port (9). (11)) is a sliding valve, which is slidably inserted into the introduction chamber (7) and located on the end face of the introduction chamber (7) in the extending direction of the stem (4).
The push button body (
5) The shape and length of the external insertion port (12) which is opened at the end is closed with one end wall (13), and the outer circumferential wall (14) is determined so as not to close the connection port (9).

(15) is an outflow groove, which is formed in the axial direction on the inner surface of the introduction chamber (7) on the opposite side from the connection port (9). (16) is a flow protrusion that protrudes from the outer periphery of the communication port (6) through an appropriate flow interval, and also communicates with the IJ (6) when the slide valve (10) is pressed down.
) shall not be closed.

With the configuration as shown above, to perform normal injection, press the top surface of the push button body (5) with your finger or the like and press the stem (4).
), the control valve inside the aerosol container (1) is opened and the contents are sprayed from the nozzle (8) through the communication port (6), introduction chamber (7), and connection port (9). be done. In this state, the external insertion port (12) is closed by the sliding valve (10), so the contents will not be spewed out, and the external insertion port (12) can be used as a normal push button. Furthermore, the push button for aerosol containers of the present invention is capable of performing refilling, pressure filling, etc., and as shown in FIG. )
Insert the valve from the external insertion port (12) and press it to open the sliding valve (
10) is pushed down, and the push button body (5) is pushed down via the communication protrusion (16), and the contents are transferred to the communication port (
6), the target aerosol container (17) is filled through the introduction chamber (7) and the outflow groove (15), and the connection port (9) is sealed by the outer peripheral wall (14) of the slide valve (10). Therefore, the contents will not be sprayed from the nozzle (8). In this case, the intended aerosol container (1
7), the target aerosol container (17) must be equipped with a control valve for refilling, and in order to use the target aerosol container (17) for pressure filling, the aerosol container (17) must be equipped with a control valve for refilling. 1) It is necessary to perform vacuum processing on the inside in advance. In this way, when performing refill filling, pressure filling, etc., there is no need to use any special adapter, etc., and the push button body (5) can be connected to the stem (4) of the aerosol container (1).
), it is possible to carry out these operations while it is attached.

Furthermore, the aerosol container push button of the present invention can be connected to an appropriate adapter (20) to expand the range of use of the aerosol container (1), and the embodiments shown in FIGS. 3 and 4 are This is related to the adapter for cleaning the bathtub, and (21) is the engagement tube, which is normally attached to the aerosol container (1).
It is formed at one end with a diameter that allows it to be detachably engaged with the mountain cup (3) of the mountain cup (3) and to be connected to the cleaning port (23) of the object to be cleaned (22) such as a bath kettle when removed from the mountain cup (3). A covering plate (24) is fixed to the other end, and a connecting part (25) is connected to the stem (4) of the aerosol container (1) on the outer surface side of the central part of the covering plate (24) and can press the stem (4). ) is formed into a cylindrical shape. This connecting part (25) is inserted into the external insertion port (12), and the engaging tube (2) is inserted into the cleaning port (23) of the object to be cleaned (22) as shown in FIG.
1) is connected and inserted, press the slide valve (]O) and the stem (4) to release the aerosol contents onto the object to be cleaned (22).
The aerosol can be injected into the inside of the object (22), and the outside diameter is such that a water hose can be connected to it, and the inside of the object (22) to be cleaned can be easily washed with water after the aerosol contents are injected. do. This adapter (20) can also be used as an overcamp for the push button body (5) as shown in FIG. 4 when not in use.

As described above, in normal use, the present invention communicates the stem and nozzle through the introduction chamber, closes the external insertion port with the sliding valve, and injects the aerosol contents, refilling the aerosol contents, pressure filling, etc. When using an appropriate adapter connected to the push button body, please use the refill stem,
By inserting the connection part of the adapter through the external insertion port and pressing and sliding the slide valve, the stem for refilling, the connection part of the adapter, etc. can be communicated with the stem of the aerosol container via the introduction chamber. , which allows for multipurpose use.
