Filed:

Feb 21, 2001

Appl. No.:

09/789471

Inventors:

Martin S. Laffey - Sylvania OH
Richard C. Sayers - Akron OH
Bradley J. Kimble - Holland OH
Gennaro R. Martire - Perrysburg OH
Wing-Kwong Keung - Perrysburg OH

International Classification:

B67D 540

US Classification:

2223831, 2223217

Abstract:

This pump dispenser has a downward tubular support providing a lead-in for a resilient closure. The closure is formed with an upwardly facing inward lead-in chamfer and spaced deep arcuate recesses in the top surface so that the wall between the recesses and the inner diameter is outwardly resilient to permit an attachment flange to stretch the wall outward and permit snap passage of the attachment flange. In this manner the closure is permanently attached to the pump body without the need for welding or separate attaching parts.

Dispensing Package Having Non-Removable And Non-Rotatable Dispensing Closure

US Patent:

Filed:

Nov 22, 2005

Appl. No.:

11/285245

Inventors:

Wing-Kwong Keung - Perrysburg OH, US

Assignee:

Rexam Healthcare Packaging Inc. - Perrysburg OH

International Classification:

B65D 39/00, B65D 41/00, B65D 43/00, B65D 47/00, B65D 51/00, B65D 49/02, B65D 17/32, B65D 41/16, B65D 41/18

US Classification:

215263, 215 28, 215237, 215317, 215321, 220268, 220780

Abstract:

A dispensing package includes a container having a neck finish with an axis, a non-circular cross section in a plane perpendicular to the axis, and at least one circumferentially extending external engagement element on the neck finish. A closure has a wall received over the container neck finish. The wall has a non-circular cross section corresponding to the non-circular cross section of the neck finish and at least one internal circumferentially extending engagement element in engagement with the external engagement element on the neck finish. The internal and/or external circumferentially extending engagement element has a shallow lead-in angle to enable press-fit of the closure onto the container neck finish and a steep back angle to retard removal of the closure from the neck finish. Rotation of the closure on the neck finish is prevented by the non-circular cross sections of the neck finish and the closure wall.

Inventors:

Wing-Kwong Keung - Perrysburg OH, US

Assignee:

Rexam Closure Systems Inc. - Perrysburg OH

International Classification:

B65D 45/16

Abstract:

A child-resistant closure includes a base, and a lid integrally molded and coupled to the base by a hinge. The lid has a latch arm resiliently extending from a periphery opposite the hinge and having oppositely extending tabs adjacent to a free end of the latch arm. The base has an external recess for receiving the latch arm and spaced ledges in the recess for engagement by the tabs to lock the lid in a closed position. The latch arm is engageable by a user to pivot the latch arm radially inwardly within the passage and release the tabs from the ledges so the lid can be pivoted toward an open position. The tabs and the ledges are recessed radially inwardly from the outer surface of the latch arm in the closed position of the lid with the tabs engaged beneath the ledges.
