Publication number: 20040089678Abstract: A dispensing cap with hinged flaps for opening and closing spoon and shake apertures in the cap end wall. The flaps, which are hinged away from the perimeter of the cap, include sealing plugs for the apertures. The plugs and apertures are formed by tooling elements on the same half of a mold to maintain very precise positioning of the plugs relative to the apertures. This precise positioning of the plugs and apertures allows them to be sized to produce a very light interference or touch fit that effectively stops moisture vapor transmission into the container and sifting of product out of the container to which the cap is fitted but, desirably, has little effect on flap opening and closing force. The sealing effectiveness of the plugs and apertures enables the cap to be used without a sealing liner for the mouth of the container.Type: ApplicationFiled: November 4, 2003Publication date: May 13, 2004Inventor: Douglas S. Martin

Patent number: 6296130Abstract: Screw on caps for bottles that have an anti back off feature formed on a hinged tab of the cap engaging detent teeth below the threads on the bottle. The hinge has a unique configuration that enables the tab to snap into and hold a gripping position while avoiding temporary distortion or creep. The detent teeth are particularly suited for use with blow molded bottles and are capable of restraining a cap within a small angle of a fully tightened position to avoid any significant back off and potential leakage. In one embodiment, the anti back off feature is provided in a child resistant cap while in another embodiment this feature is provided in a simpler continuous thread cap.Type: GrantFiled: November 20, 2000Date of Patent: October 2, 2001Assignee: Weatherchem CorporationInventors: Michael J.

Patent number: 5699924Abstract: A plastic container closure has a skirt which is connected to a tamper-evidencing band by frangible bridges, all molded in a single unit. Where the closure is a cap for a container neck, there is at least one retaining means on the skirt and another on the band. The neck has two retaining means which cooperate with those on the cap to prevent upward movement of the cap without fracture of the bridges. To reduce the likelihood of unintentional fracture of the bridges, particularly during installation of the cap on the neck, plural ejection bumpers of extended arcuate lengths are located on the top edge of the band and or from the bottom edge of the skirt and the bridges are located between the bumpers. This snap lock ring functions to replace the conventional retaining means located centrally of the band. The invention is applicable to tamper-evidencing bands of closures and of push/pull closures of sports-type cap spouts.Type: GrantFiled: April 26, 1996Date of Patent: December 23, 1997Assignee: Portola Packaging, Inc.Inventors: Nicholas A.
