Description

[Detailed Description of the Invention] The present invention relates to a button injection device whose purpose is to prevent mischief by young children and inadvertent ejection of an aerosol by making it impossible to press down the ejection button when an aerosol product is not in use.

Below, the drawings showing the embodiments of the present invention will be explained.
The button cap is provided with a locking protrusion 2 on the inner periphery of the lower opening 1, and the annular portion 3 is fitted into the mountain cap fastening portion 4 of the aerosol container and secured to the lower side thereof.

Further, an outer wall 21 rising from the annular portion 3 of the button cap A,
A bulging part 8 is provided on the left and right sides along the diameter direction by a horizontal connecting part 5 which is bent at the upper end and an inner wall 7 which is bent downward through an L-shaped step part 6 at the inner end thereof, and this bulging part A recessed portion 9 is provided in the diametrical direction between the buttons 8 and 8 and opened on the upper surface, and a groove 12 is provided in the central portion of the recessed portion 9 so as to leave the button member B and its connecting support piece 10 on the front wall 11. The button member B is provided integrally with the button cap A so that it can be operated elastically by an operating finger applied to the recessed portion 9.

The front side of the recessed part 9 is the injection direction opening 13, which is the nozzle 1 of the injection button B.
4 is opened, and a valve rod 17 is fitted into a center hole 16 of a shaft cylinder portion 15 which communicates with the nozzle 14.

The L-shaped step portions 6 of the bulging portion 8 are opposed along the diameter direction, and the horizontal portion 6a serves as a receiving portion for a slider C, which will be described later. A guide groove 17 is formed by notching along the horizontal part 6a, and a horizontal connecting part 5 is formed at the rear end of the guide groove 17 at the height of the upright part 6b.
The lower end of the groove 18 which is opened by cutting into the inner edge of the groove is continuously provided.

The slider C is a slightly wide plate part 19 that is hooked on the left and right edges 19a to the horizontal part 6a of the L-shaped stepped part 6, and is suspended horizontally on the upper surface of the recessed part 9 to cover the injection button B from the upper surface space. A guide convex part 20 is provided on a part of the left and right edges 19a of the bar, and the guide convex part 20 is received in the concave groove 18 and can be slid back and forth along the guide groove 17.

In order to prevent the guide protrusion 20 of the slider C from slipping out of the groove 18, the rear end of the guide groove 17 may be extended slightly rearward than the groove 18 to form a locking step.

When the guide convex portion 20 is located at the rear end of the guide groove 17, the plate portion 19 of the slider C widely covers the injection button B across the upper surface space, preventing insertion of an operating finger and making it impossible to press the injection button B. Furthermore, when the slider C is slid into the injection direction opening 13, the space above the recess 9 of the injection button B is opened to allow insertion of an operating finger, and the injection button B can be pressed down.

In addition, in the present invention, the injection button B is shown to be made of the same body as the button cap A together with the connecting support piece 10, but it may be an independent injection button, or the slider C
The shape may be changed arbitrarily.

As described above, in this invention, the injection button B located in the recessed part of the button cap is covered by the slider C that cuts across the upper surface space so that it can be opened and closed freely, and when not in use, the injection button B is protected from external impact by the slider C located on the vertical upper surface. On the other hand, when in use, the slider that moves forward opens up the space above the button, so it does not obstruct the operating fingers, and it can be operated smoothly with one hand without having to attach and detach it each time it is used or not. Furthermore, it eliminates accidents such as losing the device due to attachment and detachment, and is convenient for use and handling.

Claims (1)

[Scope of utility model registration request] An annular portion 3 that can be fitted onto the valve structure or end side of an aerosol container
Above this annular part, a bulging part 8 is provided which is integrally formed with an outer wall 21, an inner wall 7, and a horizontal connecting part 5 at the upper end connecting these on the left and right sides, sandwiching a recessed part of a constant width that reaches the diametrical end. On the upper side of the inner wall 7 of the button cap A, an L-shaped stepped part 6 that occupies the entire length and is recessed toward the horizontal connecting part by a vertical standing part 6b and a horizontal m6a is provided, and the opposing standing part 6b A recessed groove 18 that communicates with the groove 17 and the upper part of the guide groove 17 and a part of the upper edge of the groove is provided in the guide groove 17 and a part of the upper edge of the groove in substantially the same size range as the front and rear ends of the button member B located in the recessed part. A plate-shaped slider C that blocks this upper surface space is placed between the inner walls 7 on the upper surface of B so as to be slidable back and forth on the L-shaped step 6, and a guide protrusion that is biased towards the rear of the slider C and protrudes left and right is installed. A safety device for an injection button of an aerosol product, etc., in which a part 20 is received and supported in the guide groove 17.
