| 20120000944 | FAN ORIFICE DISPENSING CLOSURE - 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. | 01-05-2012 |
| 20110284590 | DISPENSING CLOSURE HAVING A FLOW CONDUIT WITH KEY-HOLE SHAPE - 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. | 11-24-2011 |
| 20100206916 | DISPENSING CLOSURE HAVING A FLOW CONDUIT WITH KEY-HOLE SHAPE - A dispensing closure has a flow conduit that provides a sufficient flow restriction to prevent unwanted spurting of the product when the container is initially opened. The dispensing closure includes a closure body with an upper deck and a flow conduit extending through the upper deck. The flow conduit includes an entry orifice having an entrance axis and an exit orifice having an exit axis. The entrance axis is parallel to, but not co-linear with, the exit axis to provide a non-linear flow path from an interior of the closure to the exterior of the closure. | 08-19-2010 |
| 20100065589 | DISPENSING CLOSURE WITH LATCH BACK - A closure body has a closure deck with a dispensing orifice. A lower peripheral skirt depends from the closure deck and is configured to be mounted on a container. A closure cap has an upper wall and a wall flange which depends from the upper wall. A hinge structure joins the wall flange to the lower peripheral skirt. A latch recess is defined within the lower peripheral skirt. A latch protrusion is located on the wall flange of the cap and positioned respectively positioned above the latch recess when closure cap is in a closed position. The latch protrusion and the latch recess define interfitting mating formations which engage to secure the cap to the closure body when the closure cap is in an open position. | 03-18-2010 |
| 20100065588 | DISPENSING CLOSURE HAVING A FLOW CONDUIT WITH KEY-HOLE SHAPE - A dispensing closure has a key-hole shaped flow conduit that provides a sufficient flow restriction to prevent unwanted spurting of the product when the container is initially opened. 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 outer skirt is configured to mount to a product container. The flow conduit includes including two or more vertically oriented walls and a bottom wall. The bottom wall configured and arranged to be positioned along a horizontal axis. The flow conduit includes one or more entrance orifices having one or more entrance axes 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. | 03-18-2010 |
