Publication number: 20120000944Abstract: A dispensing closure for a squeeze-type container produces a fan-type spray in a low pressure environment. The dispensing closure includes a closure body having an upper deck and a skirt depending from the upper deck. The skirt is configured and arranged to attach to a product container, such as a squeeze-type container. A flow conduit extends from an interior of the closure body and through the upper deck to provide a flow path from an interior of the closure to an exterior of the closure. The flow conduit has an entrance orifice and an exit orifice. The flow conduit has an inner wall extending between the entrance orifice and the exit orifice. The flow conduit and the closure body are integrally formed. The flow conduit includes a tip portion with an exit orifice defining a shape to provide a fan-type spray in a low pressure environment.Type: ApplicationFiled: July 7, 2011Publication date: January 5, 2012Applicant: Polytop CorporationInventors: Sergey Romanov, Clifford Skillin, Patrick Brannon

Publication number: 20110284590Abstract: A dispensing closure has a key-hole shaped flow conduit that provides a sufficient flow restriction to prevent unwanted spurting of the product. The dispensing closure includes a closure body with an upper and lower deck, inner and outer skirt, and a flow conduit extending through the upper deck. The flow conduit includes including two or more vertically oriented walls and a bottom wall. The vertically oriented walls define a fluid trapping area and a partition wall depending downwardly from said upper deck. The bottom wall configured and arranged to be positioned along a horizontal axis. The flow conduit includes one entrance orifice having one entrance axis and an exit orifice having an exit axis. The entrance axis is stepped or offset from the exit axis whereby the flow conduit provides a non-linear flow path of product from an interior of the closure to an exterior of the closure.Type: ApplicationFiled: May 24, 2011Publication date: November 24, 2011Applicant: POLYTOP CORPORATIONInventors: Patrick J. Brannon, Clifford W. Skillin, Sergey Romanov

Patent number: 7637402Abstract: A dispensing closure for viscous fluids contains a closure body, a closure lid and a living hinge structure hingeably connecting the closure lid to the closure body. The closure body includes an upper deck, a skirt configured and arranged to mount to a product container, and a flow conduit extending through the upper deck to provide a flow path from an interior of the closure to an exterior of the closure. The flow conduit includes an entrance orifice and an exit orifice, and an inner wall extending between the entrance orifice and the exit orifice. To provide the desired flow effect, the inner wall includes at least one flow inhibitor structure, such as helically threaded flights extending at least partially inwardly from the inner wall into the flow path to define an unobstructed central flow path and a partially obstructed peripheral flow path.Type: GrantFiled: May 25, 2007Date of Patent: December 29, 2009Assignee: Polytop CorporationInventors: Sergey Romanov, Clifford Skillin, Patrick J.
