Tape and tape clip

Tape measure

A tape measure having a housing that encloses a coiled tape rule retractably mounted therein. The housing is constructed with an outer coating of a generally soft, resilient, pliant material that extends over a substantial portion of the housing. The tape measure further provides a locking button that is slidably attached to the housing and is adapted to selectively prevent the tape rule from moving with respect to the opening in the housing. The locking button generally includes a central portion that is located adjacent to the peripheral wall and at least one side portion located adjacent to a side wall of the housing. The locking button further includes an outer surface with an outer coating thereon of a relatively soft, skid-resistant material. The tape measure further provides a tape clip attached to a terminal end of the tape rule that includes a friction member made of a generally soft, non-skid material attached to a clip portion of the tape clip. The friction member is advantageously mounted to the clip portion by molding the friction member within a pair of apertures through the clip portion.

The present invention is directed toward a plunger provided for use in a nozzle assembly. The nozzle assembly includes an internal chamber with an outwardly tapered portion at one end thereof. The plunger includes a plurality of outwardly curved prongs or legs which mate with an inwardly tapered portion of the internal chamber in order to allow the piston of the injector to be released from the plunger. As a result, the plunger may be removed from the injector when the nozzle assembly is removed therefrom. This plunger may include a frangible portion so that, upon firing, a first driving member of the plunger breaks away from a second driving member of the plunger. As a result of this frangible connection, the first driving member remains lodged in a distal portion of the chamber to prevent reuse of the nozzle assembly.

Plunger for nozzle assembly

The present invention is directed toward a locking mechanism for aiding in the prevention of accidental or unintentional disengagement of the nozzle assembly from a needleless injection device. In one embodiment of the locking mechanism, a stud positioned on the nozzle assembly engages a recess in the injector to help to deter the nozzle assembly from rotating during firing of the injector. In another embodiment of the locking mechanism, a nib on the nozzle assembly engages a recess in the injector to deter the nozzle assembly from rotating during firing of the injector. A retaining element may be utilized within the injector to provide the recesses for engagement with the locking mechanisms.

Locking mechanism for nozzle assembly

An injector nozzle which has a body defining a chamber. A portion of the body has an orifice which communicates with the chamber for allowing fluid to enter into or exit from the chamber. The nozzle body includes at least one depression which is configured and dimensioned to cooperatively engage a tab member of an associated component for coupling thereto. The depression is also configured and dimensioned to positively lock the body to the associated component. The body portion which contains the depression is spaced proximally from the orifice. Also, an adapter for coupling the nozzle to a fluid container. The adapter includes a tubular member having first and second ends and a wall therebetween. The wall includes a passageway therethrough with the first end being dimensioned and configured to cooperatively engage the nozzle. The orifice of the nozzle generally aligns with the wall passageway for fluid communication therebetween. The second end of the adapter is configured and dimensioned to cooperatively engage a fluid container. These devices can be used in combination to provide a system for filling an injector with medicament.
