  • Patent number: 9555221
    Abstract: A tip protector for a safety catheter includes an outer member releasably engaged with the interior cavity of the catheter hub. The outer member includes a generally fixed radially outwardly projecting portion to provide a holding force, and an inner member axially shiftably received within the outer member. A needle cannula received in the inner and outer members is operable to axially shift the inner member between a distal position wherein the distal tip extends distally of the tip protector, and a proximal position wherein the distal tip is within the outer member. The holding force of the outer member to the interior wall of the catheter hub remains substantially constant irrespective of the position of the inner member between the distal and proximal positions.

    Abstract: The present invention is an airtight case comprising a base for receiving a stick-type product, a hollow cap, and a hollow plug sleeve inserted within the cap. The plug sleeve has an open end and a closed end, the closed end being a flexible bellows.This case is useful in reducing the adverse effects caused by the pressure build-up associated with sealing or airtight cases. When the cap of the present invention is placed on the base of the case the bellows expands in response to the compressing of the air located within the inner chamber of the case, thus preventing the cap from being pulled away from the base. Also, when the cap is removed, the bellows contracts and prevents the product from being pulled out of the base.

The cap has a valve member provided with a pushing piece disposed in the inner barrel thereof, and the application ball is designed to retract from the caulked front edge of the tip when the application ball is abutted against the pushing piece of the valve member in the process that the cap is engaged with the body of the applicator, whereas the application ball is designed to disengage from the pushing piece of the tip and resume contact with the caulked front edge of the tip when the cap is fully engaged with the body of the applicator.

  • Patent number: 5338123
    Abstract: A double-ended pen has a pair of elongated liquid-holding reservoirs each having a rear end, a front end having a liquid-applying tip, an intermediate portion between the ends and having at the rear end a predetermined relatively small outside diameter, and a snap-type retaining formation. An intermediate coupling sleeve has a pair of oppositely open seats each receiving a respective one of the rear ends and provided with formations for retaining the respective rear ends securely against axial displacement. The sleeve also has a pair of axially opposite ends having axially oppositely directed end surfaces each having a portion extending at an acute angle to a plane perpendicular to the axis. The sleeve ends are of a diameter greater than the outside diameter of the intermediate portions and projecting radially therepast when the respective rear ends are fitted in the seats.

  • Patent number: 5336011
    Abstract: An improved protective storage cap for a rod-shaped device or instrument, particularly a fountain pen, wherein the female threads for securing the device within the cap are disposed within an axially and rotationally moveable ring. The ring is held stationary in the cap by the axial thrust of a compression spring while the male threads of the device are being rotationally engaged with or disengaged from the female threads of the cap. The cap cannot be overtightened and thereby damaged because further rotation of the device after full engagement of the threads serves only to overcome the restraining thrust of the spring and the moveable ring simply rotates in its cap with the device. The axial freedom of the ring and spring also permit the device to enter the cap to a depth sufficient to form a snap seal between the working end of the device and a chamber recessed within the cap, whereby the tool of the device, for example the writing nib of a fountain pen, sealingly is isolated from the outside environment.

  • Patent number: 5154526
    Abstract: Protective cap for capillary writing instruments comprised of a relatively flexible outer casing and a relatively rigid inner casing. One end of the outer casing is adapted to form a substantially fluid tight seal on the body of a writing instrument. A flexible sealing means, e.g., spherical, is positioned between the inner sheath and the outer sheath so as to form a substantially fluid tight seal on the tip of a writing instrument inserted into the inner casing and placed in contact with the sealing means. In another embodiment the sealing means located between the outer casing and inner casing is eliminated and the outer casing forms a substantially fluid tight seal by directly contacting the writing instrument tip.

  • Patent number: 4759651
    Abstract: The cap for the writing instrument comprises a jacket mounted slidably on a sealing insert or sleeve which provides a sealed moisture chamber for the writing tip when the cap is on the writing instrument. Near the writing tip there is a circular bulge on the shaft of the writing instrument which enters into a sealing engagement with an interior passage of the sealing insert. On putting the cap on the writing instrument the sealing insert is pushed over the circular bulge until it contacts a contacting stop on the jacket. Then the circular bulge presses tightly into the sealing insert and it locks the jacket to the writing instrument so that the entire arrangement is kept in that position until the cap is removed. A signal slider is attached with the sealing insert which is extendable out from the end of the jacket in order to signal in its extended position the proper seating of the cap on the writing instrument. Erroneous indications of a sealed state are prevented with our invention.
