Description
FIELD OF THE INVENTION
[0001] The present invention is directed to a flip-top dispensing
closure. More particularly, the invention is directed to a flip-top
dispensing closure having a pour spout that is open at a region
where a base portion is hingedly connected to a cap portion.
BACKGROUND OF THE INVENTION
[0002] Many consumer products such as liquid laundry detergent are
packaged in containers with flip-top dispensing closures and
continue to be popular with consumers.
[0003] Typically, flip top closures have round orifices with round
plugs that seal the orifice when the top is closed and may have
pour spouts that are also round and encircle the round orifice. The
sale of such products in containers having flip-top closures has
enhanced the consumers experience in the use of many consumer
products, thus helping to increase their popularity. However, such
conventional flip-top closures can be messy to use and do not pour
well with liquids of various viscosities, especially liquids with
high viscosity.
[0004] While many consumer products come in the form of low
viscosity liquids, new forms of consumer products having higher
viscosities, such as laundry detergents in the form of gels have
also been developed. It is of increasing interest, therefore, to
develop a convenient flip-top closure for neatly and efficiently
dispensing products such as liquid laundry detergent, as well as
other more viscous flowable product forms such as gels.
[0005] Other drawbacks associated with conventional flip-top
closures are that they often drip as they typically don't have an
anti drip lip. Also, the pouring opening is limited in size in
flip-top closures having a pouring spout since the plug for sealing
the pouring opening must clear the pour spout in order for the lid
to close.
[0006] An object of the present invention to provide a flip-top
closure that neatly and efficiently dispenses products such as
liquid laundry detergent, as well as other more viscous flowable
product forms such as gels.
[0007] It is another object of the present invention to provide a
flip top closure with a pour spout that has a pour opening that is
less limited in size due to a sealing plug than current flip top
closures having a pour spout.
[0008] Other objects of the present invention will become apparent
to those skilled in the art by reference to the specification.
ADDITIONAL INFORMATION
[0009] Numerous flip-top closures have been disclosed in the patent
literature. Such closures are illustrated in Anderson U.S. Pat. No.

SUMMARY OF THE INVENTION
[0010] The objects of the present invention are achieved in a
flip-top closure having a pour spout that is less than 360.degree.
and an anti drip lip.
[0011] In a first aspect, the present invention is directed to a
flip-top closure assembly for affixing atop a neck of a container
comprising:
[0012] a) a base portion; and
[0013] b) a cap portion that is hingedly connected to the base

[0014] wherein the base portion has a peripheral skirt for
engagement with the open neck of a container, a floor extending
inwardly from atop the skirt and having an opening therein that
defines a pour opening, and a pour spout ascending from an inward
portion of the floor, wherein the spout extends only partially
around the pour opening thereby leaving a portion of the pour
opening where there is no spout and wherein the portion of the pour
opening where there is no spout being where the cap portion is
hingedly connected to the base portion, and wherein the cap portion
has an open and close position, a peripheral skirt, a ceiling
extending inwardly from atop of the skirt, and a cylindrical rim
extending downward from the ceiling, wherein the rim forms a seal
with the base portion floor when the cap is in a close
position.
[0015] In a second aspect, the present invention is directed to the
flip-top closure of the first aspect incorporated into a container
containing a flowable product.
[0016] All numerical ranges and percentages in this specification

[0017] As used herein, the term "comprising" means that a specified
material or element is present, optionally together a further
material or element, and includes including, made up of, composed
of, consisting and/or consisting essentially of.
[0018] For a more complete understanding of the above and other
features and advantages of the invention, reference should be made
to the following detailed description of preferred embodiments and
to the accompanying drawings.

[0019] FIG. 1 is a perspective view of a flip-top closure according
to the invention with the cap in a closed position.
[0020] FIG. 2 is a perspective view of a flip-top closure according
to the invention with the cap in an open position.
[0021] FIG. 3 is a cross-section view along lines 3-3 of FIG. 2 of
a flip-top closure according to the invention.
[0022] FIG. 4 is a perspective view of a container with a flip-top
closure according to the invention.
DETAILED DESCRIPTION OF THE INVENTION
[0023] Referring now particularly to the drawings, a flip-top
closure of the invention will be described with respect to a
specific embodiment.
[0024] Flip-top closure 14 includes a base portion 40 and a cap
portion 60. The base portion includes peripheral skirt 42, floor
44, and pour spout 46. Cap portion 60 includes peripheral skirt 62,
ceiling 64, and cylindrical rim 66.
[0025] Cap portion 60 is hingedly connected to base portion 40 by
mean of hinge 80. Preferably, hinge 80 is integrally formed with
base portion 40 and cap portion 60 in a unitary structure. The
illustrated living hinge is a conventional type described in U.S.
Pat. No. 5,271,536, the disclosure of which is incorporated by
reference herein. Other hinge structures may be employed, including
a snap-action hinge as described in U.S. Pat. No. 4,403,712, the
disclosure of which is incorporated by reference herein.
[0026] Floor 44 of base portion 40 extends inwardly from the top of
peripheral skirt 42. Floor 44 has an opening that defines a pour
opening 50. Pour spout 46 ascends from an inward portion of the
floor 44. Pour spout 46 is a partial pour spout meaning that spout
46 does not completely encircle the pour opening 50 in floor 44.
Accordingly, pour spout 46 has an open region 52. Open region 52 is
in the region where the cap portion 60 is hingedly connected to the
base portion 40. As a result, the pour spout 46 extends around the
edge of pour opening 50 less then 360.degree.. Preferably, the pour
spout extends around the edge of pour opening 50 less than
300.degree., and more preferably less than 270.degree., and even
more preferably less than 240.degree.. Additionally, pour spout 46
has an anti-drip lip 56. The open region 52 in spout 46 enables the
flip top closure of the present invention to have a larger pour
opening with a spout as the open region enables the cylindrical rim
66 on the cap to have enough clearance for the cap to close.
Without this opening, the size of the pour opening and spout would
be more limited as the cylindrical rim would not clear the spout in
the region where the cap portion and base portion are hinged,
thereby interfering with placing the cap in the closed
position.
[0027] Cap portion 60 is adapted to be moved between an open
position (as illustrated in FIG. 2) and a close position (as
illustrated in FIG. 1) in which the cap portion 60 is sealingly
engaged with the base portion 40. The cap portion 60 has a
peripheral skirt 62, a ceiling 64 extending inwardly from the top
of peripheral skirt 62, and a cylindrical rim 66 extending downward
from the ceiling 64. Cylindrical rim 66 is sized accordingly so
that it fits securely within pour opening 50 in floor 44, such that
the cylindrical rim 66 acts as a plug and forms a releasable seal
with floor 44. The seal is formed with the base floor 44 and is
formed inward of the pour spout 46. Accordingly, when the cap is
closed the pour spout is outward of the cylindrical rim that forms
the releasable seal with the base floor 44. Preferably, cylindrical
rim 66 is sized such that it also touches the inside surface 54 of
the pour spout 46 as cap portion 60 is moved from the open position
to the closed position. This enables the cylindrical rim 66 to
sweep the inside surface 54 of the pour spout 46, thereby cleaning
the pour spout when the cap portion 60 is moved into the closed
position.
[0028] The cap portion may have a second cylindrical rim (not
shown) extending downwardly from the ceiling 64 that is between the
cylindrical rim 66 and the peripheral skirt 62. This second rim may
be positioned so that the spout 46 fits snugly between the first
cylindrical rim 66 and the second cylindrical rim, such that it
assist in keeping the cap in the closed position. In this
embodiment, a greater lift force may be needed to open the cap.
This can be useful to prevent the bottle from opening accidentally
and spilling the contents of the bottle or making the bottle more
difficult to open as may be desired for a child-proof embodiment.
The second cylindrical rim need not be a complete cylinder, but can
simply be a clip portion that is positioned to embrace the
spout.
[0029] It will be appreciated that while the floor 44 of the base
portion is described as extending inwardly from the top if
peripheral skirt 42, the floor 44 may extend inwardly from any
portion, not necessarily the top, of peripheral skirt 42 such as
midway up peripheral skirt 42. Likewise, the ceiling 64 of the cap
portion is described as extending inwardly from the top of
peripheral skirt 62. However, the ceiling may extend inwardly from
any portion, not necessarily the top, of peripheral skirt 62.
[0030] Referring now to FIG. 4, package 10 comprises a container 12
and flip-top closure 14. Container 12 includes a container body 16
and an upper end with a cylindrical neck 18 which includes finish
20 at its upper end.
[0031] The base portion is adapted for engagement with the finish
20 of the neck of the container. The cylindrical neck 18 of
container 12 may be threaded with external thread 22 to mate with
internal thread 48 (as shown in FIG. 3) on peripheral skirt 42.
Alternatively, the flip-top closure 14 may engage the cylindrical
neck of the container by other known means such as by snap-on
means.
[0032] Base portion 40, cap portion 60 and hinge 80 are preferably
injection molded from a thermoplastic material compatible with the
container material and contents.
[0033] Container 12 and flip-top closure 14 may be mono-layer or
multi-layer and may be made of HDPE, PP, PVC, PET, POLYCARBONATE or
acrylic or nitrite base resins, and preferably contains a minimum
of 25% PCR.
[0034] It should be understood of course that the specific forms of
the invention herein illustrated and described are intended to be
representative only as certain changes may be made therein without
departing from the clear teachings of the disclosure. Accordingly,
reference should be made to the following appended claims in
determining the full scope of the invention.
