ABSTRACT:
FIELD AND BACKGROUND OF THE INVENTION
The invention relates to a stopper-cum-metering device for the crew closure of bottles for liquids with a device for drawing up metered mounts of the product; this stopper is simple and convenient to use.
SUMMARY AND OBJECTS OF THE INVENTION
Said stopper-cum-metering device comprises a capsule with an internal thread for screwing onto the threaded neck of the bottle, which capsule forms coaxially and in one piece the cylinder of a syringe device hose plunger is worked by a rod which is graduated to allow measurement of the suction stroke of the plunger and hence of the amount of liquid drawn up.
A component internal to the capsule and positioned around the cylinder may be provided to form an annular seal that can be clamped onto the rim of the neck of the bottle by the screwing on of the capsule. Said internal component may form not only the annular seal but also, around the cylinder, an annular lip directed toward the center of the bottle; this lip is for wiping the outer surface of the cylinder during withdrawal of the capsule. Said internal component may be so shaped that it engages in the neck of the bottle when the capsule is first screwed onto the neck of the bottle. This internal component may in particular include a section capable of being forced into the neck of the bottle, being of dimensions such as to give limited interference with the internal dimension of the neck, by exploiting the elastic properties of the internal component.
The internal component that forms a lip for wiping the outer surface of the cylinder of the syringe device may include at least one hole in said lip, so that differential pressures do not develop between the outside and inside of the bottle. The shaping of the capsule and of the wiper lip may be such that the lip essentially fits an intermediate structure between the capsule and the cylinder of the syringe device; when the capsule is in its screwed position on the neck of the bottle there is contact between this structure and the wiper lip, of essentially tapering form, and the abovementioned hole is consequently closed, to ensure that liquid is not lost through said hole or holes between the intermediate structure (and hence the capsule) and said internal component that forms the seal and the wiper lip. This is especially useful when the bottle is horizontal.
