Including Rupturable Means Or Sealed-cartridge Receiver Patents (Class 401/132)
  • Patent number: 5035348
    Abstract: A flexible fluid dispenser includes a flexible fluid-containing vessel which has a seal which seals a top wall of the vessel to a bottom wall and is shaped to concentrate in a region thereof forces resulting from pressure generated by applying a force to the dispenser. When the resulting force is sufficiently large, the weaker top or bottom wall of the vessel breaks, or opens, at the concentration region of the seal. The opening has dimensions which approximate the dimensions of the force-concentrating region of the seal.

  • Patent number: 4990012
    Abstract: In writing instruments having an ink or India ink reservoir, the reservoir should remain sealed prior to first use of the instrument. For this reason, the writing tip and the shaft containing the reservoir are delivered to the user separately. When the instrument is to be used for the first time, the writing tip is screwed into the shaft until the reservoir is pierced by the writing tip. The writing instrument of the invention enables delivery to the user in which the writing tip is already screwed into the shaft without piercing the reservoir. The writing tip has a removable separator piece which comes to rest at the front edge of the instrument shaft when the writing tip has been screwed in and thus limits the screw-in depth of the writing tip, the back end of the writing tip being maintained at a distance from the plug of the reservoir.

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: 4493574
    Abstract: A dispenser package for flowable substances of the type where the flowable product is contained within a flexible pouch adhered to a relatively stiff material and may be opened along a fault line or cut pattern scored in the relatively stiff material with one hand by folding the stiff ends toward one another into a "V" shape containing one or more dimples, pyramidal shapes or other protrusions on the fault line or fault area. The protrusions not only increase and concentrate the stress forces, so that even very tough, high barrier materials may be used in constructing the package and will rupture at the protrusions by the aforesaid folding motion, but also control both the aperture shape and flow direction of the flowable substance as it is dispensed. The ability to make the package of tough materials enables the package to contain substances under pressure which subsequently will be dispensed.

  • Patent number: 4486109
    Abstract: A toothbrush assembly having a handle, a brush assembly releaseably interconnected with one end of the handle, and a massaging device connected with a second end of the handle. The brush assembly has a cylindrical base shaped to be received in a recess in the end of the handle and has an array of bristles arranged to provide a concave brushing surface. The massaging device includes a carrier having a container of liquid positioned in an internal cavity of the carrier. The container is positioned so as to be broken and dispense its contents when an end of a toothbrush is inserted into the carrier. A porous, absorbent material forms an outer surface of the device and absorbs the liquid for application to the gums of a user.

  • 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.

  • Patent number: 4360020
    Abstract: A disposable swab for application of medicament and the like to the skin, which comprises a flat, sheetlike strip and a pad member centrally attached to at least one side of the strip. The first inner pair of fold lines is transversely positioned in the strip, with each fold line of the first pair being positioned on opposite sides of, and adjacent opposite ends of, the pad member by generally equal distances, to permit opposed terminal portions of the strip to be folded rearwardly relative to the pad. A second, outer pair of fold lines may be transversely positioned in the strip, each fold line of the second pair being positioned adjacent opposite ends of the strip by generally equal distances to permit end portions of the rearwardly folded terminal portions to be pinched by the fingers together into flat, abutting relation. Accordingly, the strip can form a structure which is generally triangular in cross section, with the base of the triangular cross section carrying the pad member.

  • Patent number: 4291697
    Abstract: A cleaning device for medical purposes is provided, comprising a sealable sponge portion which encapsulates a pressure rupturable pouch containing liquid of a cleaning, antiseptic or similar nature, the pouch being sealed within the sponge. The sponge and pouch are usually sterilized following manufacture and packaging.Just prior to use, pressure is applied to the exterior of the sponge causing the pouch to rupture. This forces the liquid ingredients to spread outwardly from the sponge interior to the surface of the sponge. A fairly uniform supply of liquid on the sponge surface is thereby made available for use.A non-woven absorbent material may be sealed inside the sponge to absorb some of the liquid when it is released from the ruptured pouch. The absorbent material also functions to distribute the liquid along the sponge and provide a more uniform supply of liquid to the sponge surface.

  • Patent number: 4243337
    Abstract: The invention relates to a fountain pen of the kind requiring an ink refill, and comprising a body with a writing head at one end thereof and defining an opening at its other end, a loading clip adapted to accommodate the ink refill and to be introduced into the body via its open end, and means for closing said open end.Such a kind of fountain pen has the advantage that, because there is no separation line along the body to remove and replace the ink refill, the body of the pen can be made of a non-circular shape if required.The invention is characterised in that the loading clip comprises a base plate defining an aperture in which a front, sealed end of the ink refill can be inserted, two strips each connected at one end to the base plate and extending substantially parallel for accommodating and holding the refill between them, and a connecting element which connects the other ends of the said strips.
