  • Patent number: 4040753
    Abstract: A brush applicator instrument is provided having a compressible reservoir and valve means for selectively establishing fluid communication between the brush and the reservoir in response to compression of the reservoir. The valve means includes an extensible ferrule shiftable away from the reservoir in response to compression of the latter to thereby establish a fluid passage between the reservoir and the applicator brush such that liquid is presented to the brush only when the reservoir is compressed. An annular, flexible wall section between the reservoir and the shiftable ferrule establishes a normally sealed relationship between the reservoir and ferrule, yet due to the flexibility of the wall permits shifting movement of the ferrule relative to the reservoir when the reservoir is compressed to establish the fluid passage.

  • Patent number: 4036228
    Abstract: An osmotic device for delivering an active agent is disclosed. The device is comprised of a wall surrounding a compartment and has a passageway through the wall for dispensing the agent. The wall is formed of a material permeable to an external fluid and substantially impermeable to agent and a gas generating means. The compartment is comprised of an active agent and a gas generating means that either exhibits an osmotic pressure gradient against the external fluid, or the means is mixed with an osmotically effective compound that exhibits an osmotic pressure gradient against the fluid. Agent is released by fluid being imbibed through the wall into the compartment at a rate controlled by the permeability of the wall and the osmotic pressure gradient across the wall, which fluid wets the means causing it to react and produce an effervescent solution containing agent that is dispensed under pressure through the passageway to the exterior of the device.

  • Patent number: 4035089
    Abstract: The mechanism for varying the diameter of a body in accordance with this invention is defined by a mechanism in which the grip area intended for expansion comprises a plurality of compressible O-ring elements supported by a cylindrical body section and spaced apart by spacer elements. A stationary end plate which may be formed by the tip portion of a writing implement, forms an abutment against which an end O-ring will be forced for compression. An axially movable adjustment member is also carried on the cylindrical body for engagement with the opposite end O-ring so that as the adjustment member is moved toward the abutment member the plurality of O-rings therebetween will be compressed so that their cross-sectional shapes will be deformed from circular to elliptical thus enlarging the overall outside diameter of the grip portion.

  • Patent number: 4035090
    Abstract: An applicator comprising a reservoir and two applicator pads for applying a liquid, semi-liquid or pasty adhesive contained in the reservoir. Each pad has a duct extending therethrough parallel to the main axis of the reservoir which is preferably tubular. A removable hollow cover is provided at each end of the reservoir, the covers enclosing the pads. Each cover has a pin projecting therefrom and extending through the duct in the pad. The pin acts as a piston in its duct when a cover is removed and replaced at one end of the reservoir, forcing adhesive through the duct at the other end of the reservoir from which the cover has been removed.The pads are of sponge or flexible porous foamed plastics, and may be of different sizes. The size of each duct and its related pin are related to the size of the associated applicator pad.

  • Patent number: 4033004
    Abstract: A bookbinding machine wherein a book comprising a plurality of sheets of paper or the like to be bound together is clamped by a clamping device at a first position and the clamping device with the book is reciprocated between the first position and a second position. In the course of reciprocation adhesive is applied to one edge surface or back of the clamped book. When the clamping device has been returned to the first position after reciprocation, a cover sheet on a supporting plate is applied onto the back of the book by raising the supporting plate, which is then moved away from below the clamping device after application of the cover sheet to the back of the book so that the book may be easily taken out of the machine from below the clamping device by gravitation or otherwise.

  • Patent number: 4033700
    Abstract: A roll-on dispenser comprises a generally tubular barrel having an open forward end and a generally tubular ball-carrying member having an open rear end which is slidably received in the chamber of the barrel. The ball-carrying member has a ball applicator rollably mounted in its forward end. The rear end of the barrel is vented to the atmosphere, and a one-way follower device is slidably disposed in the barrel chamber for forward sliding movement. A cap is adapted to be threaded on the ball-carrying member and, when screwed thereon, pulls the ball-carrying member forwardly in the barrel chamber to increase the effective volume of the chamber and create a partial vacuum or sub-atmospheric pressure therein, whereupon the atmospheric pressure in the rear end of the barrel chamber will force the one-way follower forwardly by a distance corresponding to the volume of fluent material previously dispensed.

  • Patent number: 4029422
    Abstract: A tubular container, at least partially closed at one end and having a nozzle at the other end, encloses a cylindrical valve head having an applicator brush attached to one end and a valve stem connected to the other end which extends along the axis of the container. When the applicator brush is extended to operating position, one end of the valve head seats against the inside shoulder of the nozzle, preventing liquid from leaking out. In one embodiment, in which the valve head is double-ended, a partition separates a large liquid reservoir at one end of the container from an auxiliary reservoir adjacent the nozzle. When the container is upended, the brush is retracted, engaging a valve seat in the partition, trapping liquid in the auxiliary reservoir. The disclosed embodiments include at least one liquid-pervious guide rigidly fixed inside the container wall and having a circular opening disposed to accommodate the valve stem in free moving axial relation.
