Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to improvements in tip-stop buttons for foam cosmetics and other aerosol products.

(Prior Art) Many tip-stop buttons themselves have been known in the past, but there is still room for improvement in that the structure tends to be complicated and that bubbles break easily.

(Problems to be solved by this invention) The object of the present invention is to provide a tip stop button with a simple structure and good foam removal.

(Means for Solving the Problems) In order to achieve the above object, the present invention installs an L-shaped push-down lever whose lower end is fixed to the button body along the spout-side outer surface and top wall of the button body, and the push-down lever The front end surface of a ring seal enclosing the valve stem neck is brought into contact with the rear end surface of the injection window hole, and the ring seal is placed on the push-down part of the push-down lever and the top wall of the button body below it before and after the operation of the button body. It is characterized by forming a depression gap in the depression part that can be opened and closed. The L-shaped push-down lever, whose lower end is fixed to the button body, can be operated with a lever using the fixed part as a fulcrum, and when the push-down lever is operated, the push-down part will close the ring seal of the valve rod within a certain amount of time corresponding to the push-down clearance. Open and close the orifice. Therefore, at the start of injection, the orifice is opened before the button body is operated, and when injection is stopped, the orifice is closed after the button body is operated, which reduces the amount of content remaining in the passage and prevents leakage. can.

Hereinafter, the drawings showing an embodiment of the present invention will be described. FIG. 1 is a perspective view of a tip stop button A, which is a combination of a button body 1 and a push lever 2. As shown in FIG.

As shown in the vertical cross-sectional view of FIG. 2, the tip stop button A to be attached to the aerosol container B is constructed by fitting the stem 4 into the vertical hole 3 of the button body 1 and pushing the entire button into the recess on the end of the valve structure. It releases substances. The button body 1 is provided with a notch 5 extending to the top wall 1b excluding the lower part 1a on the outer peripheral surface of the nozzle side, and an outer end of a horizontal hole 6 of the injection passage is opened in this, and the rear end of the valve rod 7 is inserted into the horizontal hole 6. The parts are tightly fitted to form an integral part. From the shape of tip stop button A, valve lever 7
It is desirable that the front end surface of the button be positioned within the notch 5 of the button body 1. 8 is a ring seal, valve lever 7
the orifice 9 of the neck 7a.
to open and close freely.

A mounting hole 1 is provided at the lower edge of the notch 5 through the button body 1.
0 is provided to serve as a mounting hole for a push-down lever 2, which will be described later. The push-down lever 2 has an L-shaped side surface, and as described above, the lower end 2a is inserted into the mounting hole 10 and fixed, the front part 11 is covered along the notch 5, and the push-down part 1 is fixed.
2 is provided along the top wall 1b of the button body 1.

An injection window hole 13 is opened in the front part 11 of the push-down lever 2 so that the front end of the valve rod 7 is exposed thereto, and the ring seal 8 is provided on the rear end surface of the injection window hole 13.
abut the front end surfaces of the 14 is the top wall 1 of the button body 2
A recessed portion of a predetermined depth is formed in the top wall 1b of the lower surface of the push-down part 12 in the storage gap for the push-down lever 2 provided at b. This storage gap allows the push lever itself to be operated for a certain period of time before and after the operation of the button body. Therefore, from the viewpoint of the shape of the tip stop button A, it is preferable to form a recess in the top wall 1b, but it is also possible to make the top wall 1b a flat surface and position the presser part 12 with a certain gap above it. can also be operated.

When the push-down lever 2 is operated, if the push-down part 12 is forcibly pushed down, the ring seal 8 is released from the orifice 9 within the time to fill the storage gap 14, and the orifice 9 opens before the button body 1 is operated. Then, when the button body 1 is pressed down next time, the contents are released. On the other hand, when the pressing force of the pressing part 12 is released, the button body 1 immediately moves upward and stops the release, but there is a momentary pause until the pressing lever 2 is completely restored, and during that time the orifice 9 continues to be "open". Therefore, the residual amount in the passage is reduced, and leakage from the sealed portion of the orifice 9 is eliminated.

(Effects) As is clear from the above, the present invention allows a button to be formed with a simple structure by assembling a push-down lever to a button body to which a valve rod is assembled, and the push-down lever is attached to a button body. Since the orifice is opened and closed for a predetermined time before and after the main body is operated, the contents can be efficiently released and leakage can be reliably prevented.
