US Patent:

50057375, Apr 9, 1991

Filed:

Jun 29, 1989

Appl. No.:

7/374155

Inventors:

Robert D. Rohr - Elgin IL

Assignee:

Seaquist Closures - Crystal Lake IL

International Classification:

B65D 572

US Classification:

222212

Abstract:

A fluid dispensing closure is provided for use on a squeeze-type container. The closure includes a resilient dome member projecting convexly outwardly over the opening. The dome member defines at least one slit extending through the dome member. The dome member is sufficiently resilient to have a normally closed configuration in which the slit is sealed closed when the pressure inside the dome member equals the pressure outside the dome member. The dome member is sufficiently flexible to be deformed further outwardly from and relative to the normally closed configuration for opening the slit when the container is squeezed to exert a predetermined fluid pressure against the inside of the dome member whereby the fluid product can discharge from the container through the open slit.

Robert D. Rohr - Elgin IL

Assignee:

Seaquist Closures a divison of Pittway Corporation - Mukwonago WI

International Classification:

B65D 3700

US Classification:

222490

Abstract:

A dispersing closure is provided for an opening in an squeeze-type container and includes a body defining a dispensing passage for communicating between the container interior and the container exterior through a container opening. A flexible, self-sealing valve is provided with a peripheral flange, and the valve is mounted in the body for opening in response to increased container pressure. The body is of unitary construction and is molded from thermoplastic material with an upstanding peripheral wall that is subsequently deformed over the valve flange to retain the valve in the body. A preferred process for making the closure includes the steps of molding a unitary closure body with a seat for the valve flange surrounded by a peripheral wall, disposing the valve flange on the seat, and then deforming an upper portion of the wall into a generally annular configuration extending radially inwardly to overlie the seat and clamp the valve flange between the seat and the deformed portion of the wall.

Assignee:

AptarGroup, Inc. - Crystal Lake IL

International Classification:

B65D 5502

US Classification:

215237

Abstract:

A closure is provided for an opening to a container interior. The closure has a base for attachment to the container at the opening and defines a discharge aperture communicating with the opening. A lid is hingedly connected to the base for movement between a closed position occluding the aperture and an open position away from the aperture. A manually releasable latch is defined cooperatively by the base and lid to hold the lid closed. The lid has an outwardly projecting engaging member whereby the user can release the latch and apply a force to the member to lift the lid via the member.

Inventors:

Robert D. Rohr - Elgin IL
Lawrence R. Kitterman - Bradenton FL

Assignee:

Seaquist Closures - Crystal Lake IL

International Classification:

B67D 300

US Classification:

222517

Abstract:

A closure is provided for use on a container. The closure includes a body for being mounted to the container over the container opening and defines a dispensing orifice. A separate lid is mounted on the body for pivoting between a closed position and an open position. A resiliently deformable biasing member extends from the lid and has a distal end for engaging the body. Restraining walls are provided on the body for restraining the distal end of the biasing member whereby the biasing member is most stressed when the lid is at an over center position between the open and closed positions to thereby bias the lid toward one of the open and closed positions.

Assignee:

Seaquist Closures, A division of Pittway Corporation - Crystal Lake IL

International Classification:

B65D 4700

US Classification:

222482

Abstract:

A closure is provided for use on a container that has an opening communicating with the container interior. The closure includes a body for being mounted to the container over the container opening and for defining at least a first aperture communicating through the container opening with the container interior. The body includes a peripheral side wall outwardly of the first aperture. The closure includes a cover on the body for defining at least a first lid to cover the first aperture. The closure includes a first hinge for accommodating pivoting of the first lid between a closed position occluding first aperture and an open position spaced away from the first aperture and for connecting the first lid directly to another part of the cover or the body. The first lid includes a first engaging arm for engaging the body side wall when the first lid is in the open position. Either or both the first engaging arm and body side wall are resilient whereby the first lid is held in the open position by frictional engagement between the first engaging arm and the body side wall.

Appl. No.:

7/011111

Inventors:

James M. Beck - Carol Stream IL
Robert D. Rohr - Elgin IL

International Classification:

B65D 4132

US Classification:

215235

Abstract:

An anti-tamper container closure assembly includes a container having a orifice defining neck which receives a closure cap. The container has a plurality of projecting anti-rotation teeth positioned below the bottom of the closure cap and an overcap is adapted to be snapped over the closure cap, the overcap having a skirt with inner diameter projecting anti-rotation ribs which index with the container teeth to prevent rotation of the overcap. The overcap is effective to prevent opening of the orifice and is provided with frangeable connecting portions allowing a part of the overcap to be removed from the assembly to provide access to the closure cap for an opening actuation of the closure cap. The overcap skirt is provided with an inner diameter ledge which abuts a closure cap outer diameter ledge to prevent removal of the overcap skirt.

Assignee:

Owens-Illinois, Inc. - Toledo OH

International Classification:

B65D 4314

US Classification:

215235

Abstract:

A closure with a snap type hinge cap comprising a first part adapted to interengage with the open neck of a container, a second part forming a cap and an integral hinge interconnecting the first and second parts. Each of the first and second parts comprises a base wall and a peripheral skirt. A pair of hinge straps extends from the skirts and are positioned on opposite sides of the integral hinge. The radial length of the pair of hinge straps is less than the length of the arc through which the second cap part moves to and from and closed position relative to the first part such that the pair of straps stretch to function as springs. The ends of the pair of straps are attached to the skirts radially inwardly of the periphery of the skirts.
