  • Patent number: 4781484
    Abstract: The storage and dispensing unit comprises a container, a stoppering device and an applicator device. The stoppering device comprises a sleeve wherewith it is fitted on to the container and which carries the applicator device, and a closing cap comprising an external skirt surrounding the sleeve and an internal skirt delimiting with a top a compartment for an additional product intended to be added to that contained in the container.The cap is capable of displacement in relation to the sleeve, a bead of the skirt being disengaged from a groove of the sleeve for catch engagement in another groove, the skirt sliding in a leakproof manner around a skirt of the device, and a perforator of the cap coming during this action to pierce a foil which is carried by the device and closes the compartment, for the additional product to drop to allow the additional product into the container through the openings of the applicator device. The device is usable for the storage of nail varnish.

  • Patent number: 4747719
    Abstract: A disposable, individually packaged, self-contained topical application swab is disclosed. Liquid is initially stored in the swab and then caused to saturate the absorbent end of the swab immediately prior to application, thus eliminating spills and waste. The swab includes an absorbent material such as cotton, gauze, sponge, or the like attached to one end of a hollow plastic tube of small diameter which is sealed on the same end of the tube and which is sealed on the opposite end by a rubber cap. The unit is then inserted into a thin plastic tube of the same diameter as the absorbent material used on the swab to assure correct positioning of the swab. This exterior tube is sealed on one end by a plug containing a fixed lance. The other end of the exterior tube is sealed by the rubber cap on the swab when the swab is inserted into the tube. The entire unit may then be sterilized and strip packaged.

  • Patent number: 4578055
    Abstract: A medicament applicator having a rigid, curved delivery tube provides controlled diffusion of medicament, as well as rigidity for burnishing of tissue and removal of coagulated blood, and maneuverability for reaching desired points of application within the mouth or within an incision. The tube is curved to a pre-determined shape, and has a small amount of padding at the delivery end. Diffusion of the medicament is controlled by a pressure-applied delivery system utilizing a syringe-plunger, a syringe-capsule-plunger, a squeeze bulb or similar device. Release of the pressure-applied delivery system immediately stops the flow of medicament.

  • Patent number: 4507111
    Abstract: A surgical scrub apparatus includes a liquid-containing rupturable cylindrical cartridge which is slidable within a tubular handle having two (2) hollow interior spikes projecting longitudinally from one end. The cartridge can be inserted sufficiently far to cause rupture of the cartridge by both spikes. Liquid from the ruptured cartridge flows through the hollow spikes to an applicator sponge having two (2) wide area applicator surfaces. The hollow spikes are oriented such that one is always disposed higher than the other when the applicator surfaces of the sponge are disposed substantially horizontally. The upper spike can be disposed at a position wherein the liquid pressure applied thereto is less than ambient such that the upper spike serves as a vent passage which admits air into the cartridge. The lower spike thereby serves primarily as an outflow for liquid from the cartridge and air replaces the egressing liquid through the upper spike.

  • Patent number: 4498796
    Abstract: A surgical scrub apparatus includes a liquid-containing rupturable cylindrical cartridge which is slidable within a tubular handle having at least one and preferably two hollow interior spikes projecting longitudinally from one end. The cartridge can be inserted sufficiently far to cause rupture of the cartridge by both spikes. Liquid from the ruptured cartridge flows from within the handle, preferably through the spikes, to an applicator sponge having two wide area applicator surfaces. The spikes include exterior projections which are received in respective recesses or flow passages in the applicator to facilitate distribution of liquid through the applicator to the application surfaces. The recesses are contoured as desired to aid in liquid distribution. The interior of the spikes may be coated with a non-wetting agent such as silicone to facilitate flow through the hollow spikes.

  • Patent number: 4430013
    Abstract: This invention relates to disposable swab articles and other like packages comprising an applicator package having distal ends and having a foam applicator pad and a backing member adjacent thereto. The backing member has at least one reservoir and being formed of a relatively rigid, flat sheet material and a formed material for containing the contents of the reservoir therebetween. The flat sheet material has a slit or weakened portion in the surface of the material and the slit or weakened portion is transversely disposed of the flat sheet material, so that the slit or weakened portion is ruptured upon forcing the distal ends toward each other about the slit or weakened portion. The contents of the reservoir are thereby released into the foam applicator pad upon pressure deforming the formed material containing the reservoir.

  • Patent number: 4415288
    Abstract: An improved liquid dispensing device having particular utility as a surgical scrub and/or swab unit is characterized by a cartridge which is slidable in a rigid handle and rupturably by a spike when slid within the handle to a predetermined degree. Fluid from the ruptured cartridge flows from within the handle to within a sponge through apertures which permit free flow of the dispensed fluid. The handle may be provided with longitudinally-extending slots to facilitate compression of the handle and the cartridge disposed therein. A check valve may be included in the hollow spike passage to prevent back flow of liquid from the sponge and dispensing chamber into the cartridge.
