Flex hinge closure with drain-back channel
First Claim
1. A closure for a receptacle having a top opening, the closure comprising:
- a base portion attachable to an upper portion of the receptacle to cover the top opening, the base portion comprising;
a dispensing aperture,a raised pour lip formed along a perimeter of the dispensing aperture,a raised rib forming a closed shape surrounding the raised pour lip, anda drain-back channel defined by a space between the raised pour lip and the raised rib, wherein the drain-back channel collects excess material dispensed via the dispensing aperture and drains the excess material back to the receptacle; and
a cap portion hingedly connected to the base portion and rotatable relative to the base portion about the hinged connection between a closed position in which the cap portion covers the dispensing aperture and an open position in which the cap portion uncovers the dispensing aperture;
wherein a first material forms an integrated inner core of the base portion, the integrated inner core comprising the raised pour lip, the raised rib surrounding the raised pour lip, and one or more features that attach the base portion to the receptacle; and
wherein a second material forms an integrated component comprising the cap portion and an outer shell of the base portion, wherein the cap portion is hingedly connected to the outer shell of the base portion.

Abstract
A flex hinge closure with a drain-back channel includes a base portion having a dispensing aperture, a raised pour lip formed along a perimeter of the dispensing aperture, a raised rib forming a closed shape surrounding the raised pour lip, and a drain-back channel defined by a space between the raised pour lip and the raised rib. The drain-back channel collects excess material dispensed via the dispensing aperture and drains the excess material back to a receptacle. The closure further includes a cap portion hingedly connected to the base portion. The cap portion rotates relative to the base portion about the hinged connection between a closed position in which the cap portion covers the dispensing aperture and an open position in which the cap portion uncovers the dispensing aperture.

13. A closure for a receptacle having a top opening, the closure comprising:
-
a base portion attachable to an upper portion of the receptacle to cover the top opening, the base portion comprising a dispensing aperture, an inner core, and an outer shell overmolded onto the inner core, wherein the outer shell is restrained from lateral motion relative to the inner core by a tongue and groove fitting between the outer shell and the inner core, and wherein the outer shell is restrained from rotation relative to the inner core by one or more locking elements geometrically integrated with the tongue and groove fitting; and a cap portion hingedly connected to the base portion by a central hinge connection and a pair of periphery hinge connections surrounding the central hinge connection, wherein the cap portion is rotatable relative to the base portion about the hinged connections between a closed position in which the cap portion covers the dispensing aperture and an open position in which the cap portion uncovers the dispensing aperture. - View Dependent Claims (14, 15, 16, 17, 18)
