CHILD RESISTANT AND SENIOR FRIENDLY CAN LID
Abstract
The present invention is directed to a can lid that is child
resistant, and at the same time senior friendly, and can be
initially installed on a can to be removed by an adult, especially
a senior adult, and be put back on the can in the same condition
where a child could still not be able to easily remove it. The
child resistant and senior friendly can lid provided has a
replaceable can lid and a locking member, such that when a can is
initially opened, it may be readily resealed. The child resistant
and senior friendly can lid has tapered, smooth sides to make the
lid difficult to grasp and a sealing ledge on the inside surface to
grab the seam roll of the upper edge of the can. The lid sealing
ledge is relieved in two areas ninety degrees apart leaving a ridge
to maintain a seal when the lid is attached to a can. The can lid
will be flexible enough to bend for removal by seniors but
resistant to removal by children.

Description
FIELD OF THE INVENTION
[0001] This application provides a new and unique can lid for metal
cans that will be difficult for children to open but adults,
especially senior adults, will have the ability to open the lid and
replace it and reseal the container so equipped, readily and
easily. More particularly, a child resistant and senior friendly
can lid is provided having a replaceable can lid and a locking
member.
BACKGROUND OF THE INVENTION
[0002] Canning is the process of preserving a product by processing
and sealing it in an airtight metal can. Cans are typically either
two-piece or three-piece cans. In the case of a two-piece can, a
can body is formed by punching a metal plate to form a cylinder
closed at one end. The can is then filled and the open end closed
by seaming a lid to the can body during the canning process. In the
case of a three-piece can, a can body, open at both ends, is formed
by rolling and seaming a metal plate. A first end is closed by
seaming a lid to the can body. The can is then filled and the
second end closed by seaming a lid to the can body during the
canning process.
[0003] Once these cans are opened with a conventional can opener
they are difficult to reseal adequately. In some cases, individuals
do not want cans to be opened easily by children where they could
be carrying a harmful substance. Thus, there needs to be developed
a can lid that is child resistant and can be initially installed on
a can to be removed by an adult and then the child resistant lid
can be put back on the can in the same condition where a child
could still not be able remove it.
[0004] Numerous innovations for a Child Resistant Can Lid have been
provided in the prior art that are described as follows. Even
though these innovations may be suitable for the specific
individual purposes to which they address, they differ from the
present design as hereinafter contrasted. The following is a
summary of those prior art patents most relevant to this
application at hand, as well as a description outlining the
difference between the features of the Child Resistant Can Lid and
the prior art.
[0005] US Patent Application Publication No. 2006/0060578 of John
R. Church et al. describes a secure locking container and lid
assembly, including a resilient plastic container and lid, are
closed by snap-lock engagement of the lid in a locking groove in
the interior of the container mouth making it virtually impossible
to manually remove the lid without damaging the container assembly
or the product therein.
[0006] This patent describes a resilient plastic container and lid
but does not describe a lid for a can that is difficult for a child
to attempt to remove and may be easily removed and securely put
back on by an adult.
[0007] US Patent Application Publication No. 2015/0290699 of Paul
Charles Claydon describes a process for closing a metal can body,
suitable for containing an edible product, with a can lid, to
provide a metal can suitable for heating in a retort. The process
comprises: placing a metal lid over and in contact with an open end
of a metal can body; applying an inwardly directed mechanical force
to the lid such that at least a central portion of the lid is
deformed into the interior space of the metal can body; and seaming
the lid to the can body to form an airtight seal between the lid
and the can body.
[0008] This patent describes a process for closing a metal can body
but does not deal with a removable and resealable metal child
resistant can lid.
[0009] None of these previous efforts, however, provides the
benefits attendant with the Child Resistant and Senior Friendly Can
Lid. The present design achieves its intended purposes, objects and
advantages over the prior art devices through a new, useful and
unobvious combination of method steps and component elements, with
the use of a minimum number of functioning parts, at a reasonable
cost to manufacture, and by employing readily available
materials.
SUMMARY OF THE INVENTION
[0010] The principle advantage of the preferred embodiment of the
Child Resistant and Senior Friendly Can Lid is that they cannot be
easily opened in a conventional manner by a child, yet is readily
openable by adults, especially senior adults.
[0011] Another advantage of the Child Resistant and Senior Friendly
Can Lid is that the outer edge is tapered in and smooth and not
easy to grip or pry off.
[0012] Another advantage of the Child Resistant and Senior Friendly
Can Lid is that by weakening the inner surface at one hundred and
eighty degrees the material can flex upward to release the lid from
the can when pressure is applied.
[0013] Another advantage of the Child Resistant and Senior Friendly
Can Lid is that when the lid sealing ledge is relieved in the two
areas ninety degrees apart, a ridge is left there to maintain the
seal when the lid is attached to a can.
[0014] Another advantage of the Child Resistant and Senior Friendly
Can Lid is that one protrusion on the side of the lid allows a
gripping means to push up to open the can lid.
[0015] Another advantage is the material is malleable enough to
keep it tight on the can and soft enough for adults, especially
senior adults, to pull it off, thereby easily opening the resealed
can so equipped.
[0016] Another advantage is with the first alternate embodiment
having relief gripping sections one hundred and eighty degrees
apart on the edge of the lid for a tool strap to engage so that the
can lid will flex upward to release the lid from the can when
pressure is applied.
[0017] Another advantage is with a second alternate embodiment is
having a plurality of slots one hundred and eighty degrees apart on
the edge of the lid so it will flex upward to release the lid from
the can when pressure is applied.
[0018] Another advantage is with a third alternate embodiment is
the Child Resistant and Senior Friendly Can Lid will have relief
gripping locations one hundred and eighty degrees apart on the edge
of the lid.
[0019] Another advantage is with a forth alternate embodiment is
the Child Resistant and Senior Friendly Can Lid will have a
plurality of slots one hundred and eighty degrees apart on the edge
of the lid so it will flex upward.
[0020] Another advantage is with a fifth alternate embodiment of
the Child Resistant and Senior Friendly Can Lid will have a
securing unit to lock the can locking member in place.
[0021] Another advantage is with a sixth alternate embodiment of
the Child Resistant and Senior Friendly Can Lid will have a rubber
sealant coating applied to the lid inner surface, with the vacuum
sealing can locking member having the rubber sealant applied on the
inner surface
[0022] Another advantage is with a seventh alternate embodiment of
the Child Resistant and Senior Friendly Can Lid will incorporate a
threaded attachment between the lid and the vacuum sealable can
locking member.
[0023] The preferred embodiment of the Child Resistant and Senior
Friendly Can Lid will be comprised of two parts, a lid and a can
locking member. The locking inner member has an external locking
trough around the circumference with a narrow relief area. The lid
has a mating locking inner portion that engages within the trough
in the can locking member with a locking nib that when located next
to the relief area in the can be pressed upward to remove the lid.
An upper portion of an arrow shaped indicator is located on the can
lid and a lower portion of the arrow shaped indicator is located on
the can locking member.
[0024] The lid can be rotated so that the locking nib does not
align with the relief area and the can will remain locked until the
lid is again rotated until the two parts of the arrow shaped
indicator section come together. Preferably, fourteen (14)
restraining teeth on the inner lower edge of the can locking member
will be forced over and will engage under the can lip to lock the
Child Resistant and Senior Friendly Can Lid to the can. The number
of retaining teeth can be varied from 14 to 25 teeth.
[0025] The preferred embodiment of the Child Resistant and Senior
Friendly Can Lid will have tapered, smooth sides to make the lid
hard to grasp and a sealing ledge on the cap inside surface to grab
the seam roll of the upper edge of the can. The lid sealing ledge
is relieved in two areas ninety degrees apart leaving a ridge to
maintain a seal when the lid is attached to a can. The lid will
flex when it is pushed up where the indicia "PUSH UP" and the
lifting protrusion are located with a small tab located below to
make it easier for adults to remove the cap.
[0026] The first alternate embodiment of the Child Resistant and
Senior Friendly Can Lid will be comprised of three parts, the lid,
the can locking member and the securing unit. The lid has a mating
locking inner portion that engages within the trough in the can
locking member with a locking nib that when located next to the
relief area in the can be pressed upward to remove the lid. The
securing unit has fourteen wedge shaped teeth that are pressed
between the can locking member and the lid of the can to further
secure Child Resistant Can and Senior Friendly Lid to the can.
[0027] The second alternate embodiment of the Child Resistant and
Senior Friendly Can Lid will be comprised of three parts, the lid,
the can locking member and the securing unit. The fourteen
restraining teeth on the inner lower edge of the can locking member
have a thinner cross section and are longer and more flexible so
that they fully bend up under the can the can lip to lock the Child
Resistant and Senior Friendly Can Lid to the can.
[0028] The third alternate embodiment of the Child Resistant and
Senior Friendly Can Lid will have relief gripping locations one
hundred and eighty degrees apart on the edge of the lid for a strap
tool to engage on either side of the outer perimeter so that the
can lid will flex upward to release the lid from the can when an
upward pressure is applied on the strap tool and a downward
pressure is applied by the thumb against the lid.
[0029] The fourth alternate embodiment of the Child Resistant and
Senior Friendly Can Lid will have a plurality of slots one hundred
and eighty degrees apart on the edge of the lid so it will flex
upward to release the lid from the can when an upward pressure is
applied on the strap tool and a downward pressure is applied by the
thumb against the lid.
[0030] The fifth alternate embodiment of the Child Resistant and
Senior Friendly Can Lid will have a securing unit to lock the can
locking member in place.
[0031] The sixth alternate embodiment of the Child Resistant and
Senior Friendly Can Lid will have a rubber sealant coating applied
to the lid inner surface, with the vacuum sealing can locking
member having the rubber sealant applied on the inner surface of
the edge.
[0032] The seventh alternate embodiment of the Child Resistant and
Senior Friendly Can Lid will incorporate a threaded attachment
between the lid and the Vacuum sealing can locking member. The
vacuum sealing can locking member puts pressure on the rubber
sealing coating on the side and top of the can rim when the
restraining teeth are locked under the can rim. When the lid is
tightened down it puts pressure on the rubber sealing coating on
the lid and the vacuum sealing can locking member. The lid has a
bulbous area on the outer edge with a plurality gripping ribs
around the perimeter to aid in tightening down the lid. A second
set of gripping ribs are on the perimeter of the Vacuum sealing can
locking member helps in tightening the lid. A flexible locking tab
is located on one of the gripping ribs to engage with one of the
gripping ribs that can be bent upward to release the lid to rotate
and open the can. By pressing down on the lid, a partial vacuum
will be achieved within the can.
[0033] With respect to the above description then, it is to be
realized that the optimum dimensional relationships for the parts
of this application, to include variations in size, materials,
shape, form, function and manner of operation, assembly and use,
are deemed readily apparent and obvious to one skilled in the art.
All equivalent relationships to those illustrated in the drawings
and described in the specification intend to be encompassed by the
present disclosure. Therefore, the foregoing is considered as
illustrative only of the principles of the Child Resistant and
Senior Friendly Can Lid. Further, since numerous modifications and
changes will readily occur to those skilled in the art, it is not
desired to limit the design to the exact construction and operation
shown and described, and accordingly, all suitable modifications
and equivalents may be resorted to, falling within the scope of
this application.
