Abstract
A container cap assembly comprises an annular cap body hinged to
a lid. The cap body has a lower section with internal female
threads for cooperation with matching male threads on a container
and an annular upwardly extending flange. The lid has a downwardly
extending flange. The flanges have interlocking sealing surfaces
which extend outwardly at an acute angle to the vertical so that
the lid flange will snap over the cap body flange in the closing
mode and retain the lid in a closed and sealed position relative to
the cap body until the lid is forced upwardly.

Description
RELATED APPLICATION
[0001] This application is a continuation-in-part of application
Ser. No. 10/652,744 filed Aug. 29, 2003 entitled Container Cap
Assembly.
FIELD OF THE INVENTION
[0002] The present invention relates to a hinged cap assembly for
capping containers and particularly to large mouth containers where
a liquid tight seal is desired.
DESCRIPTION OF THE PRIOR ART
[0003] There are many known varieties and shapes of container caps
including bottle-type caps that have been and are presently in use.
The known caps differ in configuration and arrangement int hat some
are formed as just single cap members having cooperative sizes to
conform to the sizes of the containers or bottles. Some are defined
as simple snap-on caps and others are provided with internal
threads arranged to match the threaded arrangements of particular
designed containers.
[0004] Conventional snap-lid type of caps inherently do not provide
a positive seal to establish a long shelf life for liquids or
edibles stored therein. The caps are commonly formed from plastic
materials and are snapped onto the container mouth. Such bottle
caps as these are generally not provided with any type of sealing
means such as gaskets.
[0005] Threaded lids generally include gaskets, but are not handy
to use, especially for large mouth containers.
[0006] Containers and lids for storing foodstuffs and the like are
generally made of a plastic material such as polypropylene or
polyethylene polymers or copolymers. Such containers and lids are
normally fairly rigid, but may be subject to some amount of flexure
especially where the lid or cover is arranged to be peeled off of
the container mouth. Most such container/lid configurations provide
a sealing bead or rim along the upper wall of the container with a
mating channel on the lid which engages the bead as well as the
adjacent inner and outer surfaces of the container wall. Such
sealing arrangements generally require considerable effort to force
the lid onto the sealing bead during the closing procedure and
perhaps greater effort to peal the lid away from the container
during the opening process. While some lids are provided with one
or more outwardly extending tabs to accommodate a user's fingers,
the opening procedure may be quite difficult for a person suffering
from arthritis or tendinitis. In addition, the lids of such
sealable containers often become misplaced making lid replacement
difficult or impossible. See U.S. Pat. No. 4,765,506.
[0007] In some designs a separate sealing member such as an o-ring
or annular gasket is disposed between the container rim and the lid
channel to provide a more secure seal. Such designs may rely on
frictional forces to maintain the lid in place on the container or
may rely on one or more latching arms carried by the lid which
engage retention lips on the container or nut threaded onto the
container. In either case the separate sealing member, i.e., o-ring
or gasket involves not only added manufacturing costs, but is
subject to being misplaced or lost during use of the container. See
U.S. Pat. No. 5,582,314, issued to the assignee of this
application.
[0008] In addition there are closures for small mouth containers in
which a lid is connected to the cap body via a living hinge. The
lid is formed with an inner circular slot which is arranged to snap
over an upwardly extending annular flange on the cap body in the
closed position. See the digital photograph of one such closure
included in the information disclosure statement. It is not
believed that the closure would provide a satisfactory seal if
adapted to close large mouth containers and would not be easy to
open for persons suffering from arthritis or tendinitis.
[0009] There is a need for a two-piece hingeable cap assembly for
large mouth containers which is simple, relatively inexpensive to
manufacture, substantially leak proof and easy to open and
close.
SUMMARY OF THE INVENTION
[0010] The present invention comprises a container cover or lid
member hingeably mounted to a cap body that is internally threaded
so as to be readily secured to any compatible threaded neck portion
of a container. The cap body has a lower section with an inner
threaded wall, an outer wall forming a generally inwardly extending
shelf joined to an upwardly extending flange defining an annular
exterior sealing surface which tapers outwardly at an angle .theta.
with respect to the vertical and terminates in a free edge.
[0011] The lid member has a top surface and a bottom surface, a
peripheral rim or skirt and a downwardly extending flange spaced
inwardly from the skirt and defining an interior sealing surface
which tapers inwardly at an angle .lambda. with respect to the
vertical. The lid flange is arranged to snap over the cap body
flange to secure the lid member in a closed position when the lid
member is pressed downwardly with the sealing surfaces forming an
interference fit along a narrow ring circumscribing the contact
between the sealing surfaces to provide a liquid tight seal between
the lid and cap body. Preferably .lambda..noteq..theta.. The angle
.lambda. is preferably greater than X with the difference between
the angles being preferably with the range of about 2.degree. to
8.degree. depending upon the diameter of the container mouth.
[0012] In a preferred embodiment the cap body and lid member are
molded as a single piece connected together by a living hinge.
[0013] It is an object of the present invention to provide an
inexpensive, reliable and substantially leak proof hingeable
container cap assembly which does not rely on a separate gasket or
o-ring to provide the seal or a separate latch arrangement to lock
the lid to the cap body in the closed position.
[0014] It is a further object of this invention to provide a
hingeable lid/cap body for large mouth containers which is easily
opened by those suffering from arthritis or tendinitis
problems.
[0015] The construction and operation of the container cap assembly
of the present invention may be best understood by reference to the
following description taken in conjunction with the accompanying
drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
[0033] Referring more particularly to FIG. 1, there is shown a
pictorial view of a container 10 having a neck portion 11 on which
is commonly formed an external thread (not shown). It should be
readily understood that container 10 is illustrative of various
types and sizes of containers, such as bottles, jars, and the like,
that hold liquids as well as dry food products.
[0034] A container cap assembly, generally designated at 12, is
shown mounted on the container 10 and is formed from a suitable
rigid or semirigid thermoplastic material of, for example, the
polyolifin group, such as high density polyethylene, more
preferably from a polypropylene that provides some flexibility and
memory. Polypropylene is believed to be the least expensive of most
commonly used plastics for molding many consumer products and thus
advantageous from the cost standpoint. The container 10 is
illustrated as a large mouth container, for example, having a
standard diameter of 53 mm, 63 mm, 89 mm, 110 mm or 120 mm.
[0035] Referring now to the remaining figures, the container cap
assembly 12 comprises a one piece annular cap body or nut 14 formed
with a lower and upper section 16, 18, respectively, and a one
piece lid member 20. The lower cap body section is formed with
threads 16b on the interior surface 16a thereof. See FIG. 12. The
outer surface 16c of the lower section surrounds the neck of the
container, as is illustrated in FIG. 1. The lower section or wall
16 is formed with a hinge housing in the form of two spaced hubs
16d which define upwardly extending slots 16e terminating in
semicylindrical bores 16f for receiving a pair of stub axles formed
on a lid member to be described. See FIG. 14.
[0036] The upper section 18 of the cap body is in the form of an
upwardly extending flange joined to the lower section via a rib
section 19 (FIG. 12). The rib section includes a generally inwardly
extending horizontal shelf 19a and a vertically extending stub wall
19b. The flange 18 has an interior surface 18a providing
substantially unobstructed access to the interior of the container
when the lid is in the open position. The flange 18 terminates at
its upper end in a substantially flat peripheral rim 18b.
[0037] The flange 18 defines an inner sealing surface 18c which
extends downwardly from the exterior corner 18d of the rim at an
angle of .theta. degrees with respect to the vertical. A rounded
corner 18e is formed between the lower end of the sealing surface
and the web section as is shown more particularly in FIG. 12. The
bottom surface 18f of the flange forms a downwardly projecting lip
18g for sealingly engaging the top rim of the container 10. The rim
corner 18d preferably is relieved by a small radius e.g, about
0.040".
[0038] The lid member 20 has a slightly convex shaped top surface
20a, a bottom surface 20b of matching curvature and a peripheral
rim 20c, (FIGS. 3, 4, and 8). A flange 22, extending downwardly
from the rim 20c, is arranged to engage the exterior surface of the
cap body flange and provide a substantially leak proof seal between
the lid and cap body and also to releasably lock the assembly
together, as will be more fully explained in connection with FIGS.
11-13. The flange 22 is provided with an interior sealing surface
22a which is joined to a lower rounded surface 22b, terminating at
a free end 22c. The exterior surface 22d of the flange 22 is spaced
from the interior surface 20d of the depending portion of the
peripheral rim 20c as is illustrated in FIG. 13.
[0039] The sealing surface 22a of the lid flange is oriented at an
angle of .lambda. to the vertical in the unstressed condition of
the flange, i.e., when the lid is in the open position and
positioned horizontally. See FIG. 13.
[0040] A downwardly extending hinge plate 20e is formed integrally
with the lid peripheral rim and carries at it's lower end a pair of
outwardly projecting axle stubs 20f. During assembly of the lid and
cap body, the axle stubs are forced into the semicylindrical bores
16f at the end of the slots 16e in the cap body. See FIG. 14. The
slots are formed with a width slightly less than the diameter of
the axle stubs to retain the lid on the cap body. The hinge plate
includes protrusions 20g adjacent the fixed end of the axle stubs
which engage the exterior surface of the cap body lower section
when the lid is rotated to an angle of about 90.degree. from its
closed position. The protrusions tend to force the axles outwardly
as the lid is rotated past the 90.degree. angle until the lid is
positioned about parallel to the plane of the cap body, i.e., when
the lid has rotated through about 180.degree.. The lid is held in
this open position until a small force is applied to the lid to
rotate it toward its closed position.
[0041] A downwardly extending tongue 20h is positioned
diametrically opposite the hinge and is formed integrally with the
lid peripheral rim. The tongue 20h includes, at its lower end, an
outwardly extending finger engaging member 20i.
[0042] During the closing mode, the lid member is pushed downwardly
against the cap body and container causing the rounded end 22b of
the sealing flange to engage the corner 18d of the cap body flange
and flex outwardly a slight amount allowing the lid flange to
continue to move downwardly along the tapered sealing surface of
the cap body flange. The resilience of the material causes the lid
flange to flex against the tapered cap body sealing surface and
releasably lock the lid to the cap body in the position shown in
FIG. 11. This action eliminates the need for a separate latching
mechanism as required, for example, in the '314 patent. At the same
time the sealing surfaces of the two flanges form substantially a
line or narrow annular band contact 24 on or adjacent the rounded
corner 24 at the upper end of the cap body flange. See FIG. 11. It
is to be noted that a rib having s small radius adjacent the top of
the cap body sealing surface, instead of the rounded corner, would
also serve to provide an effective line seal.
[0043] The force exerted between the flange sealing surfaces along
this line contact forms a substantially liquid tight seal
preventing the contents in the container from spilling. It is to be
noted that in the event that a filled container is turned upside
down the pressure on the lower surface of the lid will increase the
pressure between the sealing surfaces to prevent leakage.
[0044] We have found that a minimum pressure of about 1.5 pounds
square inch between the sealing surfaces, with container in an
upright position, will provide the required seal while allowing the
seal to be broken and the lid opened with reasonable effort. The
container cap assembly of this invention is user friendly even to
those individuals who have limited strength in the hands as a
result of arthritis or tendinitis.
[0045] The angles .theta. and .lambda. are important in achieving
the above results. The angles .theta. and .lambda. are preferably
different with .theta. being larger than .lambda. by about .theta.
or more depending upon the size of the containers for which the
container cap assembly is designed and .lambda. can vary within the
ranges of about 14.degree. to 24.degree. and 10.degree. to
18.degree., respectively. Preferably .theta. and .lambda. are
within the ranges of about 16.degree. to 20.degree. and 12.degree.
to 16.degree., respectively. Most preferably .theta. is about
18.degree. and .lambda. is about 14.degree..
[0046] The cap body and lid are preferably injection molded from
polypropylene having a Rockwell R hardness of between about 60 and
100 and most preferably about 80. We have found that a nominal wall
thickness of 0.070" for the cap body and lid member provides
adequate strength for the assembly. We have also found that a wall
thickness t.sub.1 of about 0.045" for the neck at the upper end of
the lid flange is adequate to provide the necessary flexibility to
allow the flange 22 to flex outwardly over the rounded edge 18d of
the cap lid flange and snap into its locked position as shown in
FIG. 11 when the lid is pressed downwardly in a closing mode. The
thickness t.sub.2 of the lid flange 22 at the intersection of the
sealing surface 22a and the rounded terminal end 22b is preferably
about 0.060" to be compatible with the foregoing dimensions. The
periphery of this intersection is obviously greater than the
periphery of the adjacent section of the flange 18h (in the closed
position) to releasably secure the lid to the cap body in the
closed position. See FIG. 11.
[0047] FIGS. 9 and 10 illustrate a container cap assembly in which
the cap body is provided with integrally molded handle receiving
housings 24 located on opposite sides of the outer wall 16c. The
housings form an inner slot 24a, terminating in a semicircular
recess 24b and outer slot 24c, a handle 26, also preferably made of
polypropylene, includes a circular disk 26a mounted to each end of
the handle via a reduced diameter axle 26b. Each end of the handle
can be snapped into a respective inner slot to allow a user to
conveniently carry the container.
[0048] FIGS. 16-20 illustrate a preferred embodiment of the
invention in which a container cap assembly 12' is molded in one
piece with a living hinge 26 connecting a lid member 20' to a cap
body or nut 14'. Other than the living hinge and a modified tongue
design 20h' the cap assembly 12' is the same as the cap assembly 12
described previously. The corresponding sections of the cap body
and lid member are designated with prime numerals, e.g., the lower
cap body section is designated at 16c'.
[0049] The living hinge comprises a central section 26a and end
sections 26b with the central section functioning like an over
center spring, i.e., when the lid is rotated through a set angle
from it's closed position, say about 70.degree.-80.degree., the
central section causes the lid to rotate beyond 90.degree. and
remain in that position as is illustrated in FIG. 16. The reverse
action takes place during the closing mode except that the central
section does have sufficient spring action to close the lid.
[0050] A container cap assembly 12" is illustrated in FIG. 21,
which assembly is identical to that shown in FIGS. 16-20 except
that the lid member 20" is formed with a depressed flat top central
section 20a" to receive the bottom of a container for nesting
purposes.
