DESCRIPTION:
BRIEF SUMMARY
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is based upon PCT application Ser. No. PCT/EP 94/02149, filed Jun. 30, 1994, which claims priority from European Patent Application Serial No. 93.201.995.3, filed on Jul. 8, 1993.
The present invention relates to a childproof (child-resistant) device for holding and dispensing liquids, in particular medicines, which comprises a bottle, a cap which is irremovable from the bottleneck, said cap further being associated with a hollow cylinder extending axially to near the bottle bottom, and a reciprocating dispenser fitting within said cylinder and comprising a barrel and a plunger.
The administration of liquid medicines from a bottle normally requires that the administered amount is measured so as to agree with the prescribed amount. Well known measures are teaspoonfuls, tablespoonfuls, drops and milliliters, all of which are simply poured or taken out from the medicine bottle. Usually however, nothing prevents that the whole bottle is poured out and drunk, e.g. by children. Obviously, this problem is not limited to medicines, but also occurs with household and industrial liquids in bottles and similar containers.
A number of devices have been developed which allow a measured dose of medicine to be taken out of a bottle. Most of these are particularly designed so as to yield very accurate doses which can be selected and adjusted by the user. Less attention is usually paid to safety and the devices can often be pried open easily. Where due safety measures are provided, the resulting device is often complicated, expensive and difficult to operate. A simple and easy to handle device allowing one to take out only one single dose of medicine from a bottle at a time, is therefore felt to be an outstanding need. Abuse of major, dangerous quantities of medicine (or for that matter, of household or industrial liquids) is discouraged by requiring the user to repeat a number of uninteresting moves over and over again before such a dangerous amount can be extracted from the bottle.
The problem is solved by a device for holding and dispensing liquids such as medicines that provides precise dosages of the liquid and that comprises bottom and a bottleneck, with a hollow cylinder extending axially to near the bottle bottom and having an open upper end and a closed lower end with a central opening, and a plunger, wherein the barrel includes an upper portion having a larger diameter than the lower portion for assuring an air- and liquid-tight fit between the upper portion and the interior wall of the cylinder, and having a closed lower end with a central opening that is aligned with the central opening in the cylinder, and with the interior wall of the barrel, a graduated piston rod and a knob.
Further features and modifications as well as the advantages of the new device according to the invention will be described hereinafter in more detail, by way of example, with reference to the accompanying drawings where:
FIG. 1 shows a sectional view of a first device according to the invention;
FIG. 2 shows a sectional view of a cap with attached beaker and tear-off band; and
FIG. 3 is a sectional view of the top of a device wherein cap and cylinder are separate.
The present device (1) for holding and dispensing liquid medicines provides precise dosages of the medicine and comprises a bottle (2) for holding the liquid medicine, said bottle extending between a bottle bottom (3) and a bottleneck (4). The bottle is conveniently made out of glass or an acceptable rigid plastic such as polyethylene or polypropylene, and typically may have a capacity of 0.11.
The cap (5) is irremovably fastened to the bottleneck (4) so that it cannot be pried off. A preferred system involves mating, snap-fitting rib and groove formations at the outside of the bottleneck and the inside of the cap. This system has the advantage that it can be assembled easily and automatically and cannot reasonably be disassembled without breaking. Further, said cap (5) is associated with a hollow cylinder (6) extendin
