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

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

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
