Device for expressing substances from a deformable tube

摘要

A device for expressing a substance from a deformable tube has a casing with a base end, a top portion opposite the base end and side wall portions intermediate the base end and the top portion. A squeezer is received in the casing. The squeezer has two opposing jaws for gripping and expressing a substance from the tube. The casing has an aperture in the top portion through which a discharge outlet of the tube is extendable. The casing also has apertures in opposing parts of the side wall portions through which the jaws can be actuated. The squeezer has a manual lever element on at least one jaw, which is attached to the jaw by a fulcrum so that manual pressure applied to the lever element about the fulcrum causes flexing of the jaw and squeezing of the tube.

主权项

1. A device for expressing a substance from a deformable tube, the deformable tube having a discharge outlet with threads, the device comprising:
a squeezer having a carrier, the squeezer having a first jaw and an opposing second jaw, the first jaw extending from a jaw proximal end connected by a first jaw leg to the carrier to a first jaw distal end, the second jaw extending from a jaw proximal end connected by a second jaw leg to the carrier to a second jaw distal end, the connection of the first jaw leg to the carrier being independent of, and spaced from, the connection of the second jaw leg to the carrier, the first and second jaws diverging from one another from the proximal to the distal ends, the jaws being adapted for contacting the tube between the jaws and for expressing the substance from the tube, the squeezer having a manual lever on at least one jaw, the manual lever extending from a lever proximal end adjacent the carrier to a lever distal end, the lever proximal end being unconnected to the carrier, the manual lever distal end being attached to the jaw distal end, the squeezer having a fulcrum at the attachment of the manual lever distal end and the jaw distal end, the squeezer having a lever space between the jaw proximal end and the manual lever proximal end, the manual lever having a free portion adjacent the lever space, the free portion being unconnected to the jaw, the manual lever being adapted for manual grasping, wherein manual pressure applied to the manual lever about the fulcrum causes flexing of the jaw and narrowing of the lever space, so as to express the substance from the tube; a hollow casing extending between a base end and a top portion, the casing having a side wall intermediate the base end and the top portion, the casing having a top aperture in the top portion, the top aperture being adapted to pass the tube discharge outlet therethrough, the top aperture having a periphery, the casing having at least one slot aperture through the side wall and extending from adjacent the base end to adjacent the top portion, the squeezer being adapted to be received in the casing, the slot aperture being adapted to receive the manual lever so as to allow manual actuation of the manual lever; and a nozzle having a longitudinal axis, the nozzle extending between a proximal intake end for attachment to the discharge outlet and a distal dispensing end for dispensing the substance, the nozzle having a base portion adjacent the intake end, the nozzle having an upper portion, the upper portion having a reduced cross section relative to the base portion, the nozzle having an internal conduit extending from the intake end to the dispensing end for delivering the substance from the intake end to the dispensing end, the nozzle being adapted for attachment to the casing top portion.
