Patent number: 7549559Abstract: Resealable caps and tops for directional pour spout containers currently available for liquid and semi-solid products are either a spout and cap design, in which the tip is cut off to pour or squeeze out the container contents, or a non-spout, hinged top-and-bottom design, which defines a flat surface with an opening. These designs have many limitations. For example, the closure portion of a conventional spout closure can become detached, leading to production line delays, lost tips in transit, product recall at the store level, loss of shelf life and potential chocking hazards to children and pets. The non-spout hinged, top-and-bottom design does not offer the directional dispensing capabilities. This invention addresses the shortcomings of conventional caps and tops by providing a one-piece directional pour spout container cap in which the base has an upwardly directed spout and a hinged flip top cap is attached to the spout.Type: GrantFiled: July 22, 2005Date of Patent: June 23, 2009Assignee: Conroy Foods, Inc.Inventors: Leslee Ann Conroy, James Lawrence Conroy, William Patrick Conroy

Publication number: 20010030192Abstract: A dispenser package and outlet forming structure include a package wall (20) and a flap (30). Flap (30) is folded over at any desirable location of the package (10) and is adhesively attached to the package wall (20) at any predetermined location. Flap (30) is folded so that the surface of flap (30) that is adhesed to the surface of the package wall (20) is one continuous surface. When a pulling force exerted by a user exceeds the adhesion force between the package wall (20) and the flap (30), the flap (30) will break away from the package wall (20) causing a locus, fault, or score (40) to rupture. The rupturing of the locus, fault, or score (40) also causes the aperture outlet (50) to rupture thereby forming an outlet hole at a predetermined location for allowing the flowable product contents to exit the package (10).Type: ApplicationFiled: February 28, 2001Publication date: October 18, 2001Inventor: Sanford Redmond
