Application October 9, 1950, Serial No. 189,242

9 Claims. (Cl. 222183) This invention has to do with a liquid handling dispenser and it is a general object of the invention to provide a simple, practical, effective structure normally serving as a container or storage vessel for liquid and operable to dispense or deliver desired quantities of liquid when required.

The device of the present invention is similar in certain respects to the device which is the subject of my copending application entitled Sealed Fluid Container, Serial No. 189,241, filed on even date herewith, now Patent No. 2,679,336, and it is a general object of this invention to provide a structure useful in such situations as is the subject of the companion application and which may be employed broadly in the carrying out of the method which is the subject of the companion application.

A general object of this invention is to provide a construction which involves few simple, inexpensive parts that can be manufactured economically, which are easy to assemble, and which handle liquid with a minimum danger of contamination.

The structure as provided by the present invention involves a body in the form of a case, at least one portion of which is flexible and subject to being deflected or collapsed. The body has a neck and in a preferred form may be bottle-like in formation. A liquid carrier is provided in the body and is preferably a device or element made of rubber or the like closed at one end and having adischarge duct at the other end carried in the neck of the body with a portion folded back around the neck. A flow control device is provided on the assembly of the body and carrier and includes, generally, a mounting, a

valve mechanism, and a cap carried by the mounting and surrounding the said mechanism.

The valve mechanism is normally closed and is subject to being opened by the application of pressure to liquid in the carrier and the cap is initially provided as a seal of the valve mechanism and has a tip portion that is severable from the base or nozzle portion when the structure is to be made ready for use.

The various objects and features of my invention will be fully understood from the following detailed description of typical preferred forms and applications of the invention, throughout which description reference is made to the accompanying drawings, in which:

Fig. 6 is an enlarged detailed sectional view of a portion 2,715,980 Patented Aug. 23, 1955 of the structure shown in Fig. 3, being a view taken as indicated by line 6-6 on Fig. 3. Fig. 7 is a detailed transverse sectional view taken as indicated by line 77 on Fig. 6. Fig. 8 is an enlarged detailed transverse sectional view taken as indicated by line 88 on Fig. 6. Fig. 9 is a view similar to Fig. 3 showing another form of construction, and Fig. 10 is a view similar to Fig. 4, showing the construction that is illustrated in Fig. 9.

Referring, first, to the form of the invention shown in Figs. 1 to 8, inclusive, the structure of the present invention involves, generally, a body A, a liquid carrier B in the body and a flow control C on the structure formed by the assembled body and carrier.

The body A may, in practice, vary widely in form and construction and may be made to handle various quantities of liquid. In the typical case illustrated the body A is bottle-like in form and has a cylindrical side portion 10, a bottom 11 preferably concave in form, a top 12 and a neck 13 projecting up from the top 12. In accordance with the broader principles of the present invention a portion, if not all, of the body is subject to being flexed or depressed, as by the application of pressure on the exterior of the bottom. In the case illustrated it is contemplated that the side wall 10 of the body be flexible so that this portion of the body can be depressed or flexed as shown in Fig. 2 of the drawings. In practice it is desirable to form the body as a unit and it may be formed of various materials, for instance, rubber or a rubber-like composition, or it may be formed of a so-called plastic, it being essential only that the body be such as to normally maintain its shape and that a portion at least be subject to flexure so that pressure can be generated on air within the body.

The body A is provided with means for admitting air into the body and in the case illustrated it is shown provided with an air inlet opening or port located in the side wall 10 and in position where it can be closed by a finger or thumb of a hand employed to flex the body. The port 20 is shown provided with a removable seal 21 which may be a sheet of impervious material and, in practice, may be normally held in place by a pressure adhesive. When the structure is being used the seal 21 is removed and a finger or thumb of the user is employed to close the port when necessary.

An alternate or supplemental air inlet is shown provided in the structure. This air inlet is shown as involving a port 22 normally closed by a valve which freely admits air into the body but checks its exit therefrom. In the case illustrated the air port 22 is shown provided in the bottom 11 of the body and the valve that controls the port 22 is shown as a thin disc 23 of rubber, or the like, at the inner side of the bottom held by a stem 24 that projects through the port with clearance, and which is provided at the outer side of the bottom with a head 25. The valve unit formed by the disc 23, the stem 24 and the head 25 may be formed of rubber, or the like, and the parts proportioned and related so that one or more air passages 26 occurs beneath the head and around the stem to extend through the port 22. It will be apparent that when the pressure at the exterior of the bottom exceeds that within the body air will readily flow out from under the disc 23 and into the body. However, the structure checks the exit of air from the body. The valve controlled port just described may be used in place of the port 20 above described, or the structure can be provided with both ports for selective use, as circumstances require.

The carrier B is a seal-like element with a main portion 30 extending the length of the body, which main portion is closed at its lower end by a wall 31 and has an outlet duct portion 32 at its upper end engaged inor through the neck 13. The duct portion 32 has an exu tension 33 which is engaged around the exterior of the.

neck 13 and in the particular case illustrated the neck has a rib or bead 34 thereon, which bead is surrounded by the extension 33.

. The flow control C, as provided by the present invention, involves a mounting formed in the case illustrated by the base 40 and a top 41. The base 4G'is an annular part which surrounds thebeaded portion of the neck 13 so that the duct extension 33 of the carrier forms a seal between the base and the neck. In the particular case illustrated a flange 42 is formed or rolled inward on the base to engage beneath the bead 34 so that the base is maintained on the neck. a

The valve mechanism of the flow control C is shown A as involving an elongate projection 50 that projects upfor instance, a sleeve of rubber-like material surrounding the portion 53 and normally tight thereon so that it forms av closure preventing passage of liquid from the .ports 57. 'When pressure occurs on the fluid in the ports 57 the sleeve expands allowing such fluid to escape.

The sleeve-like valve is maintained in proper operating position between the enlargements 54 and 55.

The cap portion of the valve mechanism involves a tubular housing 60 that surrounds the valve mechanism just described. The base portion of the housing 60 is fitted tightly onto the enlarged portion 54 of the projection 50. A wall61 is carried by the outer end portion of .the housing 60 and carries a seal made up of a nozzle portion 70 and a' closed tip 71. The nozzle portion 70 is integral with the wall 61 which, in turn, is integral with the housing 60 and a suitable discharge or nozzle opening 73 extends through the portion 70 and is in communication with the interior of the structure formed by the housing 60 and wall .61. The tip 71 andnozzle'portion 70 are joined by a reduced part or neck 75 which, in practice, may be made weak or thin so that'the tip can be readily broken, severed, or otherwise removed from the nozzle portion. i a

As the structure is initially established the carrier' B is filled with liquid and in such manner that the liquid fills the entire interior of the structure to the sleeve valve 52. The housing-60 is applied tightly to the part 54 and thus encases the valve mechanism, the tip 71 being in place on the nozzle portion 70. The unit formed by the parts 60, 61, 70 and 71 may be a unit cast or otherwise formed of a material that is rigid or substantially rigid under normal conditions and is yet subject to being broken as at therneck 75 when sufficient pressure is ap- V plied.

When the structure is about to be used the tip 71 is removed by cutting or breaking the neck 75. The body A is then flexed or compressed, as indicated in Fig. 2, so that pressure is exerted on the liquid in the carrier, with the result thatthe liquid discharges past the valve 52 to'finally issue through the nozzle opening 73. As a result of either one or both of the ports and 22 air is admitted into the body by the consecutive operations or compressions thereof with consequent application of pressure to the liquid carrier each time the body is compressed. By forming the hose 60 and the nozzle portion 70 so that these parts are reasonably rigid the'structure serves to deliver a well defined stream, as established by the nozzle opening 73, and it is such that it can be readily wiped after use and the entire structure maintained in a neat condition.

In the form of the invention illustrated in Figs. 9 and 10 the valve mechanism is somewhat different than that first described. In this case the projection terminates at a valve seat 53 and the port 56 extends through the top 41 to the seat. A valve member 52 of the poppet type is normally held in engagement with the seat 53, as by a spring 90, and in the case illustrated the spring is shown under compression between the valve 52 and the end wall 61 on the housing 6%]. from the drawings how this valve mechanism operates to pass liquid out of the carrier each time pressure istapplied, as by inwardflexure of the body."
