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.
