r claim. (01.222-34'0) ThisV inventionv relates` generally tothe dispensing. ot a Huid lsuch as lotions, liquid soaps, hair oils, etc., and? particularly to a fluid dispensing device'. Y
The main object of this invention is .tofconstruct a uid dispenser which is easily attacha-ble to a container from which the lluid may be forcibly ejected in measured quantities without wasting the iluid or being untidy or unsanitary.
The second object is to construct a device in a manner consistent with modern methods of producing objects from plastic materials and also in a manner to reduce to a minimum the weight of the parts required to avoid the excessive use of the plastic material.
The third object is to construct a device of the class described wherein a positive ejection valve is employed to insure the delivery of a predetermined quantity of liquid regardless of the speed or the manner in which it is operated.
The fourth object is to provide a modied form of ejection thereby for use in connection with materials having diierent degrees of viscosity.
I accomplish these and other objects in the manner set forth in the following specification as illustrated in the accompanying drawing, in which:
Fig. 1 is a side elevation of same in place on a bottle.
Fig. 2 is a plan of Fig. 1.
Fig. 3 is a vertical section of the device taken along the line 3-3 in Fig. 2.
Fig. 4 is a section taken along the line 4-4 in Fig.
Fig. 5 is a bottom view of Fig. 3.
Fig. 6 is a view similar to Fig. 3 but showing the operating button depressed.
Fig. 7 is a plan of a modified form of the device, not especially adapted for light or fast flowing fluids such as liquid soaps, hair oils, etc., but intended for thick iiuids, creams .and hand 1otions.
Fig. 8 is a fragmentary section taken along the line 8 8 in Fig. 7.
Similar numerals refer to similar parts throughout the severalyiews.
Referring in detail to the drawing, there is shown the common form of .bottle IU having a threaded neck (not shown). On the neck of the bottle I is screwed the internally threaded neck II of my device which is provided with a somewhat aring base I2 having the hollow portion I3 for lightening purposes. The threads I4 may be of any convenient type.
A dividing wall I is provided with a central my device showing l in the cavity 33 by the bottom 35.
opening FSL which is in alinementwith the: opening in the neck of thebottle I0.
The wall I1? forms onev end.` of: the= device'above the dividir-1gl wall' I:5` while ther rounded; wall' I8 forms a secondf end wall for the space above the member I5. The sides I9` are tangent4 to: the members II and I8. A cover 20 is provided with a friction rim 2| and placed over the compartment 22 formed within the members I6, I'I and I8. The cover 20 has a cylindrical recess 23 formed at the bottom thereof which terminates in the uppermost cylindrical portion 24 of somewhat less diameter than is the portion 2'3.
In the top side of the member 20 is formed a cylindrical cavity 33 in the center of which 'is formed a tubular wall 34 which is supported v Within the tubular wall 34 is disposed a piston 36 provided vwith a sealing ring 31. The piston 36 is formed on the piston rod 38 which also guides within Ithe tubular wall 34. The lower end 39 of the prod 38 is U shaped and its upright portion 40 Jis integral with the hub 3 I On the upper end of the rod 38 is formed a cylindrical head 4I which is pressed into the cap 42 of the hollow push button 43. The push button 43 can move freely within the cylindrical cavity 33. A spring 44 of suitable compression strength is interposed between the push button 43 and the bottom 35, encircling the tubular wall 34.
It will be seen that the pressure of` the nger 45 upon the button 43 will move the button 43 to the position shown in Fig. 6, causing the piston member 32 to move downwardly as shown in Fig. 6 and permit fluid to flow between the ribs 25 into the space 24 when the bottle I0 is inverted or turned on its side. As the button 43 is released, the liquid is trapped in the cylindrical portion 24, the instant the disc 32 passes the shoulder 46 causing material to be ejected from the opening 28.
In the form of the device shown in Figs. 7 and 8, there is a slight modiiicationin which the tip 29 and the inner end 30 are omitted and the the operating pressure is stored up in the spring nger 45, so that the rebring about the ejection 44 by means of the lease of the finger will of the materials. tunity for a playful or mischievous person to use this device as a gun or spray, as it is incapable of exerting a greater force than is stored up within the spring 44 itself.
While plastics would, in most cases be prefererable, it is obvious that in many instances die casting could be employed to advantage.
While I am aware that numerous forms of uid dispensing devices have been invented in the past, I do not intend to cover all such devices broadly,
Moreover, there is no oppor-v but I do intend to cover all such forms and modifications as fall fairly Within the appended claim.
I claim:
The fluid dispensing device consisting of a threaded bottle cap having a chambered recess formed between the threaded portion thereof and the closure therefor, said closure having an inwardly opening cylinder formed therein, said cylinder having a piston normally occupying same, said cylinder having extension guides for supporting said piston when withdrawnfrom said cylinder, said closure having an opening therein through which fluids may be ejected by said piston, said closure also having an outwardly opening cylindrical cavity formed therein within which is a tubular wall communicating between the interior of said chambered recess and the atmosphere, a piston Within said tubular wall, a U shaped piston rod connecting the two pistons and extending outwardly from said tubular member, a hollow push button within said outturned cylindrical cavity having a spring therein surrounding said tubular member, said push button being secured on the outer end of said projecting piston rod.
