Abrégé anglais


A closure for a container of the kind use to deliver milk and juice. The
closure is a two-piece
construction comprise of a lid and a base. The closure preferably has overall
dimensions that
approximate a standard unitary cap use with the same containers, so that the
closure can easily be used
with standard feeding equipment in a bottling facility. The closure has a
hinge that is formed of a post
connected by a tab to the lid, and hinge supports extending upwardly from the
closure's base. The
hinge supports include a hook and a bridge. The hook allows the tab to slide
under the hook during
assembly of the lid to the base. Once the tab is positioned between hook and
the bridge, the hook
bocks disassembly of the lid from the base. The post of the hinge assembly
fits within tunnel sections
formed by the hook and the bridge, and gripping forces applied by the hook
and/or bridge hold the lid
in an open position when contents are poured from the container.


Note : Les revendications sont présentées dans la langue officielle dans laquelle elles ont été soumises.

We Claim:
Claim 1: A closure comprising:
a base having a skirt and at least one internal thread formed on an inside
surface of the skirt, the
base having an opening;
a lid having a depending plug shaped to fit at least partially into the
opening of the base;
a hinge joining the base and the lid, the hinge comprising:
a post carried by the lid, the post being integrally connected to the lid by a
tab;
at least two post supports extending upwardly from the base, one post support
being a bridge
having a first end and a second end, each of the ends of the bridge being
integrally joined to the base,
the bridge defining a first tunnel section adapted to receive a first portion
of the post, a second post
support being a hook with a proximal end being integrally joined to the base
and the hook having a free
distal end, the hook forming a second tunnel section adapted to receive a
second portion of the post, the
first and second portions of the post being separated by a middle portion of
the post, the middle portion
being joined by the tab to the lid.
Claim 2: A closure of claim 1 further comprising:
a beveled portion on the free distal end of the hook, whereby during assembly
of the lid to the
base, the beveled portion will guide the tab under the distal end of the hook.
Claim 3: A closure of claim 1 further comprising:
a buttress formed adjacent an intersection of the proximal end of the hook and
the base, whereby the
buttress provides the hook with improved resistance to bending from upward
forces applied to an inner
surface of the hook by the second portion of the post.
Claim 4: A closure of claim 1 further comprising:
the at least one thread formed on an inside surface of the skirt being a
single helical thread adapted to
mate with a single helical thread on a bottle, whereby the closure when
installed on a bottle having a

handle will generally have a single alignment in which the direction of
opening of the lid will
correspond to the location of the handle.
Claim 5: A closure of claim 1 further comprising:
a first latch bead on the base and a second latch bead on the lid, the first
and second latch beads being
positioned to snap past one another and hold the lid in a closed position over
the opening in the base.
Claim 6: A closure of claim 1 further comprising:
the post having at least one generally axially extending external rib, the rib
being deformable when the
post is inserted into at one of the tunnel sections.
Claim 7: A closure of claim 6 wherein the post has eight generally
axially extending
external ribs, the ribs being generally equally spaced about the perimeter of
a portion of the post and
each rib having a height of about 0.003 inches.
Claim 8: A closure of claim 1 wherein the bridge and the hook have a
height that is
approximately equal to an elevation of an upper surface of the lid when the
lid is attached to the base,
and the base includes a platform from which the bridge and hook extend
upwardly, the bridge and hook
being disposed in plan view within the periphery of the closure, whereby the
hinge does not extend
either radially from the closure beyond the skirt or axially a substantial
distance beyond the lid, when
the lid is assembled to the base.
Claim 9: A closure of claim 1 wherein the skirt has a lower skirt
section and an upper skirt
section, and axially extending knurls are disposed over a major portion of an
exterior surface of the
lower skirt section, an upper portion of the skirt section being with knurls,
such that the top of the
knurls form a shoulder, and the lid having a downwardly depending lid skirt
that is shaped to fit around
an upper portion of the skirt, the lid skirt having a thickness that is
approximately equal to the depth of
at least some of the knurls.
Claim 10: A closure of claim 1 wherein the lid is made of a plastic
containing a first
11

colorant, and the base is made of a plastic containing a second colorant, and
the first and second
colorants are different.
Claim 11: A two-piece closure comprising:
a base having a skirt a thread formed on an inside surface of the skirt, the
base having an
opening;
a lid having a depending plug shaped to fit into the opening of the base;
a hinge joining the base and the lid, the hinge comprising:
a post carried by the lid, the post being integrally connected to the lid by a
tab;
a post support extending upwardly from the base, the post support being
integrally joined to the
base and defining a tunnel section adapted to receive a portion of the post,
the tab being joined to the
lid by a tab;
the hinge being disposed substantially within a space defined by a plane
corresponding to the
upper surface of the lid, and a cylinder generally corresponding to an
outermost portion of the skirt.
Claim 12: A closure of claim 11 wherein the post support is comprised of
two upwardly
extending formations, one formation being a hook having a fixed end and a free
end, and a second
formation being bridge having two fixed ends, each of the hook and bridge
defining a tunnel section
for receiving portions of the post.
Claim 13: A closure of claim 12 wherein a beveled portion is formed on
the free end of the
hook, whereby during assembly of the lid to the base, the beveled portion will
guide the tab under the
distal end of the hook during a sliding assembly of the lid to the base.
Claim 14: A closure of claim 13 wherein the tab has a width that is less
than a distance that
separates the hook and the bridge, such that when the tab slides under the
free end of the hook and is
disposed between the hook and the bridge, the hook moves in the direction of
an original position of
the hook and the free end of the hook blocks the tab and restricts disassembly
of the lid from the base.

Claim 15: A closure in accordance with claim 11 wherein the lid includes
a colorant that is
not present in the base.
Claim 16: A closure in accordance with claim 11 wherein the base has a

the perimeter of a portion
of the post and each rib having a height of about 0.003 inches.

of the skirt, the
base having an opening;
a lid having a depending plug shaped to fit at least partially into the
opening of the base;
a hinge joining the base and the lid, the hinge comprising:
a post carried by the lid, the post being integrally connected to the lid by a
tab;
at least two post supports extending upwardly from the base, one post support
being a bridge
having a first end and a second end, each of the ends of the bridge being
integrally joined to the base,
the bridge defining a first tunnel section adapted to receive a first portion
of the post, a second post
support being a hook with a proximal end being integrally joined to the base
and the hook having a free
distal end, the hook forming a second tunnel section adapted to receive a
second portion of the post, the
first and second portions of the post being separated by a middle portion of
the post, the middle portion
being joined by the tab to the lid;
the hinge being disposed substantially within a space defined by a plane
corresponding to the
upper surface of the lid, and a cylinder generally corresponding to an
