"Valve actuation button for Aerosol container "

The invention relates to a valve actuation button for aerosol containers with a cavity in the lower part of the button to accommodate the dispensing valve shaft and a recess for receiving a rotatable plug, at least partially eddies between the cavity and the dispensing opening forms, so that the amount of material exiting through the dispensing opening is regulated by turning the plug.

Buttons of the type mentioned can be placed on the tubular valve stems of aerosol containers v / earth and have a line inside to a

gate Opening from which the material is dispensed in spray form. Usually these buttons are designed in such a way that the type and extent of the spray cone remain essentially the same as time progresses.

js, attempts have been made to get the buttons designed so that the amount and type of spray at the outlet is as desired by the operator can be changed. However, these older designs are very cumbersome in the majority of cases, by the usual injection molding process difficult to cut out and often by the operator been difficult to work with.

The object of the present invention is to provide extremely simple button constructions that are economical and efficient in the injection molding process suitable plastics can be made and allow fine adjustment so that the dated Button outgoing spray gel changed within fairly wide limits according to the wishes of the operator can be.

According to the invention, the characteristic feature of a valve actuating button of the type mentioned

In the embodiment according to FIGS. 1 and 2, the head consists of a body or main part 1 with a cavity 2 at the lower end _{p to} accommodate the tubular valve stem of an aerosol container. ₉ as shown for example in German patent 842 563 «, ■

In the upper part of the button there is a recess 3t and in this recess there is a rotatable plug or stopper 4 which is provided on my upper part with a pinger 5 protruding from the side. The finger sits in a sector-shaped one. Cutout in the upper part of the body “ land this cutout has a sufficient arcuate dimension to allow the pinger 5 to be waved back and forth so that aea?

Will against it the pinger 5 in the opposite sense of the word <> as indicated by arrow 13 in Fig. 1 "rotated, the line 10 causes parts of the opening 9 to gradually release j, so that correspondingly larger amounts of aerosol enter the overall line through the plug to the outlet opening can occur «By such a regulation of the position of the finger 5, the user can adjust the scope of the gas or The liquid flow to the outlet opening and thus the amount of aerosol to be dispensed from the container regulate β

In the embodiment according to FIGS. 1 and 2, the flow line is closed off at the upper end of the opening 9 the parts in the position shown in Fig. 1, wherein the line 11 is wide enough. to the outlet opening not to be blocked in any position of the finger 5 *

3 and 4 show an embodiment in which the flow line for gas or liquid is closed at the inner end of the outlet opening 12a. In this figure, the opening 9a? which of the opening 9 corresponds to _{9 arranged} coaxially with the plug 4a. The passage 10a is always in communication with the opening 9a, but the line 1ta is made relatively narrow, as shown in FIG. 3, so that its width is just about equal to the diameter of the inner end of the outlet opening 12a. In the position shown in Fig 3 ₀ of the finger 5a covers check the line 11a completely to the outlet port 12a, a maximum of S-as "· or liquid flow so that achieved by the knob. However, if the finger 5a clockwise _s moves as indicated by arrow 13a in Figure "3 * is given the over-

is l & ppung the line 11a increasingly reduced with the outlet 12a, moves to the pinger in Uhrzeigersian over the whole distance _s 9a completely whereupon the line 11a not overlapped with the discharge port 12a, and the lines 11a and 10a for gas or liquid as well as the opening at the outlet opening are closed. An execution of this kind is particularly desirable? when colors or other fast drying ₉ ~ Calling or hardening substances are to be sprayed? because by closing the outlet opening at the dispensing opening, the color in the button does not dry or harden and also does not make the button ineffective for dispensing such liquids. In other than the above-mentioned relationship, the parts of Figs. 3 and ■ 4% the same as in the embodiment of Figure "1 and 2.

The modified embodiment of the invention according to F 5 and 6 ultimately embodies the combination of the features shown in Fig. 1 through 3 4 inclusive, dean in Fig. 5 and β the opening 9b is eccentric as shown in Fig. 2 _P and the passage 10b - is brought into register with or separated from the opening 9b. At the same time the line is 1tb _? which the line configured 11a 'correspondingly narrow in Fig _Q 3 and corresponds sodaJ they also 12b to complete or close the inner end of the discharge port can 5 and 6 accordingly show a double closure of the flow conduit ₉ when the plug from the finger 5b corresponding to "Figure" is operated »

In the button of FIGS. 7 and 8, the partition wall 8e is with two openings 9c and 9cc are provided, which are spaced from each other on both sides of the axis of the plug 4c »

The Durchlai3 10c, which leads to the line 11c _? which corresponds to the line 11 of FIGS. 1 and 2, is a T-piece with the "two arms 14 and 15 _S which are to each other and to the openings 9c and 9gc. That with a position of the pinger 5c _p as shown in Fig 7 is shown, the arm 15 is in connection with the opening 9c * while it does not coincide with the opening 9c "If, however, the finger 5c is moved in the counterclockwise direction", the arm is increasingly crashed into coincidence with the opening 9c, while the arm 15 is still in communication with the opening 9cc. In this way, the arm 15 and the opening 9ce are constantly connected to one another _p gana, which is the position of the finger ₉ so that the smallest possible amount is sprayed, "G-leiehaeite. the user can increase the amount to be sprayed by the amount of overlap ^ of arm 14 vmä opening 9c. In this version, both openings 9o and 9cc are never completely closed together «

In the button shown in FIGS. 9 and 10, the opening 9d in the partition 8d is arranged eccentrically to the axis of the stopper 4d, while the passage 10d on the underside of the stopper is provided with two annees 16 and 17, the first of which is smaller than the second and both of which open into the common passage 10d, which leads to the line 11d. By turning the stopper 4d through the finger 5d of this embodiment, a smaller passage 16 can be made to coincide with the opening 9d _P so that relatively little is sprayed, while the line 17 can be brought into congruence with the opening 9d in order to spray a larger amount, as it is at the discretion of the user »

In the case of the button in FIG. 11, "12 and 13" is the partition

8e provided with a single opening 9e * while the underside of the plug 4e has a diametrically extending passage 10e? As Fig. 13 shows, the passage narrows in the longitudinal direction. When the finger 5e is in the position shown in Fig. 11, _P is the flat part of the passage 10e in register with the opening 9e ₉ and a relatively small amount of the spray to be sprayed Material is directed to the outlet opening * However, if the knob is turned clockwise, a larger part of the deep part of the passage 10e is brought into congruence with the opening 9e and a correspondingly larger part of the liquid is dispensed through the outlet opening. User can adjust the amount of au sprayed agent regulate in this way by simply rotating the plug, although it is no provision in this particular _embodiment} to the flow line by the button to shut off "

In the button shown in Figs. 14 and 15, the partition wall 8f is provided with an opening 9f corresponding to the opening 9a. This opening is coaxial with the plug 4f and at every 2 @ it in correspondence with the passage 10f ₅ of the line 11f leads? the _p as best from S ¹ Ig. 14 it can be seen that _{p is} of a tapered arc shape "When the finger 5f is in the position shown in FIG. Dispensing opening 12f, and consequently the flow line consisting of parts Hf, 10f and 9f is closed at the dispensing opening 12f. If, on the other hand, finger 5f is rotated clockwise. _? so constantly larger cavities of the tapering * curved line 11f with the discharge opening 12f are in process

dung brought ρ and a correspondingly larger flow of liquid is dispensed through the named outlet »In this way, the user can dispense as desired control simply by pressing the finger 5f «

16 and 17, the partition wall 8g is provided with two openings 9g and 9gg, the last of which is larger than the first which open into the common line 10g to the line 11g., which corresponds to the line 11 of FIGS. 1 and 2. If the finger 5g rises in the position of FIG give maximum quantity of liquid through the button ^ but the finger sense 5g egenuhrzeiger in ^& ~ moved ρ so the arm is brought from its connection with the opening 9gg _p while the arm 18 in accordance with the opening 9g comes to a substantially lower amount Direct liquid to the dispensing opening.

Which are shown in the drawing, in all embodiments of the invention _9, · the portion of the flow-line for gas or liquid within the stop ~ fen generally be referred to as Stopfendurchlaß, while the parts of the flow conduit within the
Body of the button commonly referred to as body lines xtferden «

It should be noted that in the various figures the arrow-shaped part 20 is formed by a depression in the button surface and indicates the direction in which the outlet opening points , so that the user knows how to hold the container ₉ when the button is pressed «
