29, 1944. Divided and ary 16, 1941, Serial No. 2,356,755, dated August this application August 21, 1944, Serial No. 550,437
The object of this invention is to provide means for dispensing liquids, particularly those that must be kept sterile, and safeguarding the antisepsis until the separated amount of liquid is put into actual use. The present application is divisional to that from which matured Patent #2,- 356,755, granted August 29, 1944.
The device consists of the combination of three elements: first, a bottle or like container, the inner wall of its neck being provided with a discharge passage; second, a stopper to be inserted removably and rotatably into the bottle neck and formed with a discharging duct that extends from the inner to the outer end portion of the stopper and its inner outlet registering with the said discharge passage of the neck; and third, a smaller container, for instance, a phial, detachably mounted on the said stopper in communication with the outlet of the said discharging duct of the stopper. The passage from the bottle to the p-hial is closed or opened respectively by a relative rotation of the stopper.
One embodiment of the invention is illustrated by way of example in sectional elevation in the accompanying drawing.
Container I has a neck 5, and is provided with a stopper 2, formed with an eccentric duct 3, through which communication can be established at will between the interior of the container l, and an external aperture 1, and to which a phial 8 can be removably connected. The duct 3 may terminate at its lower end 6, as here shown, in the peripheral surface of the stopper registering with a recess 4, formed in the neck of the bottle, through which the duct 3 communicates with the interior of the bottle in one position of the stopper, whereas when the stopper is rotated about its axis into another position of the stopper, the inlet 6, of the duct 3, no longer registers with the recess 4, and is consequently closed in a fluid-tight manner by the internal peripheral surface of the bottle neck 5.
The external aperture 1, at the outer end of the duct 3, is provided with suitable coupling means, such as an internal screw thread, whereby the phial 8, may be mounted in fluid tight connection with the duct 3. To efiect the transfer, the stopper 2 is rotated until the inlet 8 registers with the recess 4, and the bottle is then tilted to pour the liquid from one vessel to the other through the duct. The air originally contained in the phial passes up the duct in counter-current to the liquid; for very small bottles, or for viscous liquids, it might however be necessary to provide a closable vent for the escape of this air.
The form and the positioning of phial 8, and
its joints, can be shaped in accordance with varied requirements, for instance, for the phial to be in a horizontal position during the pouring to facilitate accurate measurement, on the lateral surface of the stopper 2.
1. In a dispenser for liquids, the combination with a bottle having a neck, of a stopper rotatably inserted in and sealing said neck and formed with a discharge passage extending from the inner to the outer portion of the stopper, said neck being formed in its interior periphery with at least one discharge passage with which said passage of the stopper is registrable in one rotational position of the stopper, whereby opening and closing of the stopper passage is effected by rotation of the stopper, and a small container detachably mounted on the outer portion of the stopper in air-sealed communication with the discharge passage of the stopper.
2. In a dispenser for liquids, the combination with a bottle having a neck, of a stopper rotatably inserted in said neck and formed with a discharge passage having an inlet thereto in the peripheral face of the inner portion of the stopper and extending convergently to the stopper axis to the outer portion of the stopper, said neck being formed in its interior periphery with at least one discharge passage with which said passage of the stopper is registerable in one rotational position of the stopper, whereby opening and closing of the stopper passage is efiected by rotation of the stopper, and a small container detachably mounted on the outer portion of the stopper in air-sealed communication with the discharge passage of the stopper.
