MOUNTING CAPS FOR AEROSOL DISPENSER Filed Sept. 17, 1964 INVENTOR. SEI CH KITABHYASHI United States Patent O 3,270,924 MOUNTING CAPS FOR AERGSL DISPENSER Seiichi Kitabayashi 2-2246 Nishisugamo, Toshima-ku, Tokyo, Japan Filed Sept. 17, 1964, Ser. No. 397,333 Claims priority, application Japan, Sept. 19, 1963, 38/49,4tl6 1 Claim. (Cl. 222-394) The present invention is concerned with mounting caps for aerosol dispensers having a pressure container containing a liquid under pressure, a discharge valve means and a push button for operating said valve means, with said push button having an emission nozzle.
An object of the present invention is to provide yan economically produceable and especially a mass-produc tion feasi-ble sealing means for aerosol containers containing a gas dissolving liquid generally under several atmospheric pressures.
Heretofore, mounting caps for sealing .means for aerosol dispensers, regardless of whether bottles -or cans, are `made of metal plates. They are of a cup-like form having a brim at the upper edge. The cup-like portion is inserted into the mouth of a bottle or can and said cuplike portion is fixed to the container by means of enlarging sidewards the side wall lower portion of the cup mechanically for sealing -the container mouth.
Accordingly, old or known mounting caps cannot be fixed to cans or bottles without a special machine tool. Moreover, good aerosol dispenser articles often do not result from the above-mentioned mechanical work.
However, according to the present invention, not only the above-mentioned drawbacks of old mounting caps for aerosol dispenser are removed but the present invention can provide a big advantage in the mass-production of aerosol dispensers.
The effects and advanatges of the present invention will be better understood by reference to the following description taken in connection with the accompanying drawings, in which:
FIG. 1 is a vertical sectional view of a mounting cap for an aerosol dispenser according to the present invention mounted on the mouth end portion of an aerosol container and equipped with a discharge means.
FIG. 2 is a vertical sectional view of a modified form of the mounting cap for aerosol dispenser according to the present invention mounted on an aerosol container and equipped with 'a discharge means.
A mounting cap for aerosol dispenser according to the present invention comprises a disc 1 molded in a resilient synthetic resin with said disc having an annular wall member 2 pendent from lthe bottom face thereof and a tubular member 6 extending upwards at the center thereof. Said annular wall member 2 -has an outer wall face 3 for engaging an aerosol container mouth 4 lower end at the upper portion of said wall face. Said tubular member 6 is provided with a lower bore 8, communicating with the opening in said disc bottom face, and an upper bore 9, of smaller diameter than the bore 8, and closed at its upper end. A step 18 in the member 6, above the bore 8 provides an annular recess 6a, coextensive at its upper end with the closed end of the small bore 9. A plurality of side orifices 10 extend between the recess 6a and the smaller bore 9.
lCe
The mounting cap for the aerosol dispenser according to the present invention is mounted on an aerosol container 5 by inserting the annular wall member 2 in the container mouth 4. The diameter of the container mouth should be designed equally to the diameter of the annular member outer wall 3 and a little shorter than the same. The annular wall member outer wall 3 engages most solidly with the container mouth lower edge if the same edge is designed for being bent inwardly as shown in both figures. The mounting cap cannot be fixed for sealing the container mouth by a mere insertion of the mounting cap annular wall member 2 in the container mouth. However, when the container 5 is filled with a pressure gas or a liquid under pressure the container inner pressure charges in the direction of the arrow a, or in the direction for pushing out the mounting cap, as well as said pressure charges in t-he direction of the arrow b, or in the direction for holding the annular wall member 2 to the mouth edge 4. Yet, as the annular member 2 is molded in a body with the disc 1 in a resilient synthetic resin, the same member 2 bends toward the mouth edge 4 and is held solidly to the same for completing la gastight seal of the container mouth.
As described above, -a mounting cap according to the present invention is not fixed to an aerosol container by a special ymachine tool as with an old mounting cap but is fixed solidly by means of simply filling the container.
A mounting cap for an aerosol dispenser according to the present invention has a tubular member 6 molded as one body with the disc 1 and which tubular member 6 enables the structure of the discharge valve for aerosol dispenser to be very simple. 11 is a rubber ring forming a part of a discharge valve and seated in recess 6a normally closing side orifices 10 communicating with the tubular member axial bore 8. A push button 12 is mounted on the rubber ring 11 `and is provided with a lower cavity 13 facing ring 11 and an upper cavity 14 with said cavities being connected to each other and to an emission orifice 15.
When the push button 12 is pushed downwards the rubber ring 11 yields outwardly, and the side orifices 10 com municates with the emission orifice 15 for emission of aerosol pushed up by the container inner pressure.
A steel ball 16 shown in FIG. l serves as a check valve means for preventing refilling of the container through the tubular member axial bore S. And, small slits 17 are provided in the annular wall member 2 of the modified mounting cap of FIG. 2 serves for enlarging the bend of the same member at the insertion of the same in the container mouth. 7 is an eductor tube for aerosol solution.
Having thus described my invention what I claim is:
A mounting cap vfor aerosol dispensers comprising a disc of a resilient synthetic resin having an annular w-all member pendant from the bottom face of said disc and a tubular member extending from the center of the upper face of said disc, said annular wall member having an outer lwall face capable of closely engaging the lower end of the mouth of the aerosol dispenser at an inner portion of said outer wall face, said tubular member being provided with a peripheral step, an axial bore closed at one end and opening at said disc bottom face and side orifices opening above said peripheral step and in said bore adjacent the closed end of said bore, a rubber ring having a pair of ends with one end mounted on said annular step normally closing said side orices, a push button being mounted on said rubber ring other end and having an emmision orifice, inner cavities communi eating with said orice and one of said inner cavities facing said rubber ring for receiving aerosol material 5 from said side orifices when said push button is moved against said rubber ring and thereby opens said side orifices.
