Abstract: A closure assembly for the dispensing of fluids from plastic containers such as pails. The closure assembly is adapted for automated insert molding attachment to container lids. The closure assembly is pre-assembled from a threaded plastic closure cap and closure body prior to insert molding. The plastic closure body has a nestable and extendable conical body web leading inward to a body neck closed by a tamper evident diaphragm seal. The conical body web leads outward to an improved radial body clamp flange and novel cylindrical body skirt. Cap bails lie radially inside and brace the body clamp flange from distortion. Once inserted and clamped into the container lid mold, only the body skirt is exposed for attachment to the container lid. Molten plastic is introduced into the mold void to form the container lid. This patent discloses optional body skirt recesses.

Abstract: The present invention is an improved plastic industrial container which may be used for packaging, shipping and dispersing a variety of liquids while protecting the contents from tampering and theft. The container is manufactured in components which include a pail body, a cover and a nestable pour spout closure. The improved container design facilitates press fit assembly of the cover to the pail in the usual manner, but which blocks tool insertion and undamaged removal of the cover. The invention specifically relates to an improved cover and closure combination which facilitates the press fit assembly of the closure to the cover but which resists tampering. The barrier molded with thin cross section with frangible elements to be easily damaged if tools are used in a prying manner on the closure wall resist tampering by restricting the clearance for tool insertion and closure removal.

Abstract: A closure for attachment to a cover having an opening presenting an upstanding rim, comprising a body having an annular top wall, said top wall merging with spaced inner and outer walls defining a depending body recess for capturing said rim, said outer wall having threads extending generally outwardly therefrom and the top wall presenting a notch; a cap having a top, said top presenting a projection disposed for alignment with said notch, an outer wall depending from said top, said outer wall having threads for engagement with the threads of said body outer wall.

The improved container design facilitates press fit assembly of the cover to the pail in the usual manner, but which blocks tool insertion and undamaged removal of the cover. The invention specifically relates to an improved cover and closure combination which facilitates the press fit assembly of the closure to the cover but which resists tampering. A molded cover sump and top plastic barrier wall closely surrounds the installed closure. The sump and barrier wall resist tampering by restricting the clearance for tool insertion and closure removal. The barrier wall is further molded in thin cross section with frangible elements to be easily damaged if tools are used in a prying manner on the closure.

Abstract: A closure for a container cover opening, said opening defined by an upstanding cylindrical wall with a beaded rim, said closure comprising a circular closure bottom, inner wall, top wall, outer skirt and outer flange presenting an annular recess for engaging said cylindrical wall and said beaded rim; a pull ring; said pull ring connected to the exterior of said top wall; said closure to be removed by inserting a finger through said pull ring and lifting said closure off said beaded rim.

Abstract: A closure for a container having an opening, comprising a baffle having at one end a surface for blocking communication with the opening, an orifice at a top end of the baffle for communicating with the opening.

Abstract: In a closure for a container having an opening presenting an upstanding circular bead, said closure comprising: a closure body presenting a spout for dispensing liquids from said container, said spout including an annular recess for releasable securement to said bead; a cap releasably securable to said spout; a lock ring frangibly connected to said cap, said lock ring aligned with said closure body, said annual recess and said bead, said lock ring frangibly breakable from said cap to lock said closure body to said container.
