The present invention relates to the use of magnetic lifting devices, in particular, the device which allows to move objects within a container.
Art is replete with various devices that use magnets to move various parts. One of the prior art methods is a method of testing whether a magnetic lifting device may safely lift a particular load where the magnetic lifting device is placed adjacent to the load, some or all of the magnetic elements of the magnetic lifting device are spaced such that the lifting ability of the magnetic lifting device is reduced by a predetermined amount. An attempt is then made to lift the load by a small safe distance. If this attempt is successful, the user can be sure use of the magnetic lifting device, when the lifting ability is restored, is safe.
Conveniently, the spacing is achieved by the introduction of a substantially planar member between the magnetic lifting device and the load. The planar member has a similar footprint to that of the magnetic lifting device. The planar member may be made of stainless steel. A magnetic lifting device may incorporate magnetic elements which may be spaced such that the lifting ability of the magnetic lifting device is reduced by a predictable amount, for example it may incorporate a moveable planar member.
Another prior art reference teaches a permanent magnet-type lifting device for lifting heavy steel articles or the like in which a magnetic assembly of ferrite magnets stacked to form a single unit between pole pieces of a magnetically permeable material is rotatably disposed between plural magnetic member magnetically isolated from one another. In a preferred embodiment, plural rotated assemblies are provided and are mechanically linked through a common rotation mechanism. The magnetic member have an attracting surface and an inclined portion extending toward the attracting portion.
To the extend effective, none of these devices can be used in smaller environments such as containers and boxed for holding food items and medical elements such as bandages, wipes, and the like, specially when it is uncomfortable to remove the contents by using hand and fingers.
To the extent as being effective, there is always a need for new and improved devices for moving parts within containers.
A container includes a body having inside and outside surfaces, a bottom and an open top covered by a lid in order to seal the content located or stored inside the container. The container can be used for holding potato chips and other products for human and animal consumption. A lifting device includes a platform, having a central portion and a pair of legs extending from the central portion and having magnetic elements connected thereto to engage with inside surface of the container.
A pair of metal elements of a generally rectangular or generally circular configurations and are attached to the outside surface of the container. The metal elements are held at the outside surface because the magnetic elements will prevent any movement of the metal and magnetic elements. A user can move the metal elements along the axis A thereby moving the central portion with the chips from the bottom towards the top to remove the potato chips and other products from the container without placing hand and fingers inside the container thereby avoiding any contamination, avoid any movement and any unnecessary damages to the product located inside the container.
A first alternative embodiment of the container includes a body having inside and outside surfaces, a bottom, and an open top covered by a lid. The container presents at least one track on the outside surface of the container extending from the bottom to the top. The track can be defined in the body by any mechanical means such as press formed, molded in, mechanically attached, without limiting the scope of the present invention.
The container may include a pair of the tracks. The track is used to house a metal element secured in the track and movable along the track slidable along the track to move the central portion and the pair of legs within the inside of the container to move the contents between the bottom and the top of the container. Alternatively, the track may partially extend between the bottom and the top without limiting the scope of the present invention.
A second alternative embodiment of the container presents a rectangular cross section. The container has four walls. A lifting device includes a platform of the lifting device having a central portion and a pair of legs extending from the central portion and having magnetic elements connected thereto to engage with the inside surface of the container.
An advantage of the present invention is to provide an innovative method for extracting object such as potato chips and other products from the container without placing hand and fingers inside the container thereby avoiding any contamination.
Another advantage of the present invention is to provide the innovative container with a lifting device and using magnets wherein the container is easy to manufacture.
