Theupper end of the body'10 is, recessed and-shouldered as indicated at 13 to receive thecap. I
The bottom, of the container body- 10 has centering projections 14 whichare angularly=spaced fromone another and. support arigid syphon tube-15 in; anelevated position, in orderfro-permitv the contents of the container to enter. the lower end thereof; The top-capll isser- .ratedtaboutitsperiphery as indicated at. 16v to-providea good grip upon. the.container: and: to render the bottl e or, eont ainctattrac tive.and of. pleasing appearance I I The top cap 11 has a central depending skirt portion 1 f,7 and an upwardly-extending neck .or outwardlyrextending nipple 18 that has adepressed tconical top face 19 fla in ntwardw from a, central discharge opening. 20 adjacent the lower end of which is an internal. valveseat 21 frorn which the upper end 22f of a flexible, two-way springless valve 22' normally bulges or balloons due to the pressure of the contents, as shown in Fig. 2 tolhold s qnt nt e t ne p nding ro th pp r 's'eatin'g lend 22"of the; valve 22 is a straight cylindrical Wall that maintains ,control of the sjeating'end 22 when itis depressed fronrits seat 21. The valve is hollow and has an' annular portion 25 withescape holes 26 therein. Thisfi-ang'e portion is dished on its top surface and the upper end of'rig'id' syphontube 15 bears against its lowerasurface to hold the valve 22 within the sleeve por- I tior12:1:7-1at 'the outer periphery of the flange 25 against a 1 Qfi'aQtaperedand cylindrical internal. neck wall 28,;915 V the'cap surrounding the cylindrical valve wall 23 are a plurality of angularly-spaced guide fins 28 which guide the upper end 22 of the valve 22, when it is depressed. A vertical recess 29 extends to the seat 21 at one side of the nipple wall to carry a portion of the contents,
head from being disengaged therefrom due to the pressure of the contents. The dispensing head 33 is formed of flexible plastic and has aflexible diaphragm 34 adapted to be depressed so that its bottom face will be pressed toward or engage the depressed conical surface 19 of the nipple 18 to close ofi the space therebetween at times when the contents of the container are being dispensed to thereby minimize the loss of the contents after the flow of the contents has been discontinued.
In the center of the diaphragam 34 is an integral hollow stem 35 that depends downwardly and protrudes outwardly therefrom. This stem 35 is relatively thick and rigid and has radially extending angularly-spaced metering slots 36 on its lower end so that any of the contents passing over the valve and under the seat 21 will be metered to a central hole 37 in the stem and upwardly therethrough. These slots 36 may be varied in size and number depending upon the nature of the contents and spray form which is desired. Several heads with different slots may be economically provided. The assembler may snap over the neck and physically try the different heads to get the desired spray pattern for the given contents to be dispensed.
The outwardly protruding end of the stem 35 is sufficiently long to accommodate a spray discharge press button 38 having a downwardly curved top surface 39 i for receiving a thumb or finger by which the same is depressed. The press button sets upon and is tightly fitted to the end of the stem. The press button 38 has a side spray orifice 41 leading from a mixing chamber 42 with the central hole 37 of the stem 35. A lightening hole 43 extends into the press button 38 to reduce the weight and bulkiness of the press button 38.
The press button is small and thus press buttons with different size spray orifices and mixing chambers may be economically provided. ,By a change from one button to another, when taken with a change of one dispensing head for another, the package or container can be easily adapted for the diiferent fluids to be dispensed and the spray pattern desired. p
A decorative over-cap 44 can be fitted over the pressure button 38 and frictionally secured upon the dispensing head 33. This over-cap is a part of the package when purchased and may be retained therewith throughout its use. It prevents the accidental and inadvertent pressing of the button 38 and waste of the contents.
To dispense the contents, the over-cap 44 is removed, and the press button 38 is easily depressed with the forefinger while holding the package in the hand. This press button pushes down the stem 35 and the flexible diaphragm 34 of the dispensing head 33 so thatthe lower end of the stem 35 forces the upper end 22 of valve 22 from its seat 21 in the manner illustrated in Fig. 3, thereby permitting the contents to escape upwardly through the openings 26 of the valve, vertical recess 29, under the seat 21, through the radial metering slots 36, stem hole 37, press button chamber 42 and discharged from the button spray orifice 41. All this time there is little opportunity for the contents to accumulate under the diaphragm 34 in any great amount so as to 4 be later wasted, as the bottom face of the diaphragm will substantially close upon the conical face 19 of the nipple leaving little chamber space about the discharge opening 20 for the contents to accumulate.
Upon release of the press button 38, the diaphragm 34 is quickly returned to its initial position by the action of the internal pressure of the contents upon the valve and by the aid of small amounts of expanding propellant gas accumulated under the diaphragm so that the flow of the contents is quickly shut off and discontinued.
It should now be apparent that there has been provided a dispensing head for pressurized containers adapted for cooperation with the nipple portion of the top cap which is so formed and shaped as to permit easy deflection of the valve element to dispense the contents and a quick return of the head diaphragm to cause a sharp and quick out 01f of the flow of the contents and wherein the contents are kept confined within a small space about the nipple portion so that there is little loss of the contents after, release of the finger from the dispensing head.
It should also be apparent that there has been provided dispensing head parts for pressurized containers which are inexpensive to manufacture and which permit the use of heads with different size discharge slots and press buttons with'difierent size mixing chambers and spray orifices so that the assembler can quickly try 7 upon the container several until he gets the spray form desired.
While various changes may be made in the detailed construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.
What is claimed is:
In a pressurized container, a container assembly having an outwardly-extending nipple portion thereon, said nipple portion having a discharge opening and a seat adjacent the lower end of the discharge opening, a valve element operable in the nipple portion and normally retained against the seat by the pressure of the contents within thecontainer, said nipple portion having a depressed conical outer end face flaring outwardly from the outer end of the discharge opening, a flexible dispensing head tightly fitted upon the nipple portion and having a depressible diaphragm overlying the conical end face, said diaphragm having an integral tubular projection depending into the discharge opening of the nipple portion and through which the contents is discharged, said tubular projection being engageable with the valve element to force the valve element from its seat, upon the dispensing head being depressed, said diaphragm normally lying awayffrom the conical faceof the nipple and seated upon the conical end face when depressed to minimize the space thereunder whereby to prevent the contents from collecting under the diaphragm when the container is used and the ultimate loss thereof.
