DISPENSING UNIT FOR SEALED PRESSURIZED CONTAINERS This application is a continuation-in-part of copending application, Ser. No. 869,592 filed Oct. 27, 1969.

SUMMARY OF THE INVENTION A dispensing unit which includes a base for holding a plurality of scaled pressurized containers and which provides vertical support and guide posts for a common dispensing tube which extends parallel to the base and which in turn provides a plurality of penetrating points for puncturing simultaneously each of the pressurized containers, the dispensing tube being operatively associated with a single rotatable control lever which moves the same upon the support and guide posts into and out of contact with the sealed pressurized containers.

The dispensing tube is normally closed at one end and is provided at its opposite end with a valve head which includes a valve stem carried by a hose-connecting core.

GENERAL DESCRIPTION The invention will be best understood by reference to the accompanying drawing which shows the preferred form of embodiment and in which:

FIG. 1 is a perspective view of the dispensing unit;

FIG. 2 is a fragmentary detailed sectional view of the operative parts of the invention.

Referring to Fig. 1, the dispensing unit of this invention includes a base provided with a plurality of circular recesses 11 which receive and position a plurality of sealed pressurized containers 12 (shown in dotted lines).

Extending vertically from the base 10 and between the recesses 11 are a pair of rods 13. These rods may be connected to the base 10 by suitable nuts 14 which may be countersunk in the bottom wall surface of the base as indicated by Fig. l.

Embracing the rods 13 and seated upon the top wall of the base 10 are a pair of washers 15. These washers 15 act as a stop for coil springs 16 which are coiled about the rods 13 throughout one-half of their longitudinal length. Engaging the top of the coil spring 16 are stop washers 17 which are fixedly carried by the exposed ends of sleeve members 18. These sleeve members 18 are journaled through and close openings 19 and 20 formed in the dispensing tube 21. The rods 13 have their upper exposed ends threaded as at 22 and receive thereon a common connecting plate 23. The connecting plate 23 is by a pair of nuts 24 adjustably connected between the threaded ends 22 of the rods 13, as shown in Fig. 1.

Midway between the rods 13 and threadable through an opening 25 formed in the middle of the connecting plate 23, is the threaded shank 26 of a turnscrew 27. The exposed and 26' of the shank 26 of the turnscrew 27 is rounded so as to be seated in a curved depression 28 formed in a boss 29 formed on the top wall portion of the dispensing tube 21.

The dispensing tube 21 is provided on its underside with a plurality of circular collars 30, 31 and 32, each of which has open communication with the interior passage 33 of the dispensing tube 21. Positioned within the collars 30, 31 and 32 and as more particularly shown in Fig. 2, is a compressible seal 34 which encompasses a hollowed penetrating tube 35. By the tube 35 open communication is provided therethrough with the interior passage of the dispensing tube 21.

One end of the dispensing tube 21 is normally closed. The opposite end provides a dispensing valve head 36 which includes a valve passage 37 and a valve stem 38. This valve construction is of a type well known in the industry and is operative when a connecting hose is threaded upon the valve head 36, which hose provides a corresponding valve stem depressing member which opens the valve passage through the valve head 36.

In operation. a plurality of sealed pressurized containers are placed upon the base 10 within the recesses 11 provided thereby, with the dispensing tube 21 raised upwardly u n the rods 1 After the containers are thus placed upon t e base 10, the dispensing tube 21 is permitted to slide down the rods 13 until the penetrating tubes 35 engage the metallic cover of each of the sealed pressurized containers. The operator then turns the turnscrew 27, which will thread itself through its connection to the connecting plate 23 and have its curved end 26' bearing against the correspondingly formed seat 28 provided by the bushing 29 on the upper side of the dispensing tube 21, until the penetrating tubes 35 puncture the tops of the sealed containers. At this time the pressurized contents thereof will have open communication into the hollow bore 33 of the dispensing tube 21 and when a suitable hose is con nected to the valve head 36, such contents will be dispensed therefrom.

The downward movement of the dispensing tube 21 through the action of the turnscrew 27, will move the sleeve members 18 carried thereby against the coil springs 16 which embrace the rods 13, so that when the containers are emptied and the turnscrew 27 is rotated in an opposite direction, the springs 16 will raise the dispensing tube 21 out of contact with the containers 12 so that they may be readily removed.

By reason of the recesses 11 formed in the base 10 which are positioned relative to the location of the penetrating tubes 35, as provided by the underside of the dispensing tube 21, each of such penetrating tubes 35 will be centered upon the pressurized containers and will properly and simultaneously puncture all of the containers as desired.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:

l. A dispensing unit for sealed pressurized containers comprising a. a base support providing a plurality of recesses for positionably receiving a plurality of sealed containers,

b. a common dispensing tube carried by said base support in an elevated position with respect to the top of the containers,

c. means carried by said tube for penetrating the plurality of containers positioned on said base support,

d. a pair of support rods for supporting said tube in an elevated position relative to the containers positioned on said base support and over which said tube moves so that said means carried thereby will simultaneously penetrate all of the containers positioned on said base, said rods extending vertically from said base in horizontal alignment and parallel to the containers supported thereon, said rods freely joumaled through sleeves connected to and passing through said dispensing tube, with said sleeves and dispensing tube movable relative to the longitudinal length of said rods and to the top of containers mounted on said base support,

e. means for moving said tube relative to said support rods and with its penetrating means into piercing contact with said containers so as to permit passage of the pressurized contents of the containers into said dispensing tube, and

f. a dispensing valve carried by said tube through which all of the pressurized contents of the containers are valved.

2. A dispensing unit as defined by claim 1 wherein said means for moving said tube relative to said support rods comprises a turnscrew extending parallel to said support rods and having one end thereof in contact with said dispensing tube for moving said dispensing tube and said sleeves connected thereto over said supporting rods so that said means carried by said dispensing tube will simultaneously penetrate all of the containers positioned on said base support.
