A dispensing container having a neck with a throat opening closed by a cap having a pierceable membrane adjacent atop of the cap, the cap having a dispensing nozzle with a lumen therethrough and an overcap for enclosing the dispensing nozzle having a moveable plunger pin extending into the lumen of the nozzle and moveable therein to pierce the membrane.

Pierceable dispenser container and closure

A tube having a needle piercing membrane closing the threaded opening of a tube neck is provided with a screw-on nozzle defining cap having an internal stopper projecting into the mouth opening to the throat, the stopper sealingly engaging the perforated mouth opening and terminating adjacent the membrane.

Threaded closure for tube opening

An apparatus for applying a liquid to a surface comprising an applicator and a body member. The applicator is secured to an end of the body member, the body member defining a reservoir for housing a fluid. The body member includes a piston member for exerting a force on the fluid in the reservoir, and two channels, a first channel being in fluid communication with a channel in the applicator and a second channel being in fluid communication with an area outside the body member. The body member further including a valve for allowing fluid communication between the reservoir and either the first channel or second channel. An additional one-way valve which can be manually deactivated may be included in the second channel.

Reservoir fluid dispenser with control valve

Abrasive articles, such as finger nail files, are made by stamping a metal sheet to form a blank with a header strip having a plurality of spaced fingers depending therefrom, coating the fingers with a slurry of abrasive granules and flowable plastics material adhesive, curing the coating to anchor the abrasive particles to the fingers, vacuum depositing a thin strike coating of copper or copper alloy over the cured resin coating and then electro depositing a coating of nickel over the vacuum deposited copper. The abrasive granules are preferably aluminum oxide, the resin carrier for the granules is preferably an epoxide thermosetting resin, and the metal coatings are controlled to form thin sheaths around the resin coating leaving the peaks of the abrasive granules exposed or only covered with very thin coatings which break off or wear away when subjected to friction. The cured, abrasive particle containing resin coating is sufficiently stable to resist deterioration during the vacuum coating operation which is carried out in several sequential stages initially releasing gases in the resin coating, then melting the copper, increasing the vacuum and temperature to vaporize the copper and then depositing the vapor on the fingers forming a sheath around the resin coating.
