Such a stopper is illustrated in Figure 6.
The squeeze bottle 46 is of smaller size than the stock bottle 40, and is provided with a restricted exteriorly screw-threaded neck 48 which is of such dimensions and proportions that it can be readily fitted into the interiorly screw-threaded neck 42 of the stock bottle 40.
Instead of the perforated disc or gasket 24 of the bottle 14, a more restricted passage or opening 50 is provided in the neck 48 of the squeeze bottle 46, whereby only a relatively small quantity of the liquid 60 can be dispensed, and this restricted opening 50 facilitates the transfer of the liquid 60 from one container to the other by reason of the alternate compressing and releasing operation previously described.
It will be evident that herein is disclosed the concept of a close system of liquid transfer through a very small opening by simple control of pressure changes within the system. Pressure increases inside the entire system and consequent expulsion of air from the squeeze-type dispensing container are effected by manual compression of theplastic resilient smaller container. Pressure decreases and returns to approximate atmospheric pressure inside the system, and resultant liquid transfer from the larger stock liquid container to the smaller plastic dispensing container are eifected by release of pressure on the resilient container, and this is especially true when the system is held in such a position so that the stock liquid container is inverted.
The fundamental principles described in the above manner of liquid transfer can be extended to a system utilizing a stock liquid container with female threads replacing the standard exteriorly threaded container, and such will eliminate the necessity of the coupling, provided of course that the neck of the flexible dispensing container is exteriorly screw-threaded so as to accommodate itself and snugly fit into the interiorly screw-threaded neck of the stock container.
As shown in Figure 7, the cap 12 of the larger bottle can be dispensed with, and the coupling 20, together with the stopper 44 used as a permanent closure element for the stock bottle 10. In that event, the coupling 20, as
shown in Figure 1, can be omitted from the kit.
I am aware that many changes may be made and numerous details of construction varied throughout a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon otherwise than as necessitated by the prior art.
I claim as my invention:
1. A coupling for stock containers and squeeze bottles whereby the latter may be refilled from the stock container, said coupling comprising a unitary tubular element interiorly and reversely screw-threaded at its ends to accommodate the correspondingly exteriorly screwthreaded necks of the respective stock and squeeze bottles, the outer end of the squeeze bottle neck having a restricted opening, said restricted opening comprising perforated disc mounted on the outer end of the squeeze bottle neck, said disc mounting comprising a liquid and airtight sealing relationship and an exteriorly screw threaded closure element for the stock bottle.
2. A method of transferring liquids from a stock bottle to a squeeze-type dispensing container, comprising connecting the bottles by a coupling, compressing the squeeze bottle to provide a pressure within the connected system and expel air from the squeeze bottle into the stock container, and thence releasing pressure on the squeeze bottle, whereby liquid is transferred from the stock bottle to the squeeze bottle by reason of a higher than atmospheric pressure in the stock bottle, and a lower than atmospheric pressure in the squeeze bottle.
3. A method as described in claim 2, wherein the coupling comprises a third element of tubular shape interiorly screw-threaded at each end to receive the necks of the stock and dispensing containers.
4. A method as described in claim 2, wherein the coupling comprises an interiorly screw-threaded neck for the stock bottle, and an exteriorly screw-threaded neck for the squeeze bottle.
5. A method as described in claim 4, wherein a restricted passageway is provided in the squeeze bottle neck.
6. A method as described in claim 4, wherein a disc having a restricted perforation therein is mounted on the outer end of the neck of the squeeze bottle.
