Abstract
A flexible, hardened material created for the added stability, rust prevention and safety for all users of propane cylinders, tanks, canisters or the like. The composition of device can vary in flexibility, hardness, color, composition, shape or size. The molding/forming of the device can include but is not limited to injection molding, rotational molding, blow molding, compression molding, transfer molding, silicone molding and vacuum thermoforming. The device can be formed from a composition which may include, but is not limited to, rubber, thermoplastics, polymers, and synthetics of various durometer. The device can be non-electrostatic and can protect against ambient ground electrostatic charges.
Claims24
A cover for a tank comprising:
- a top portion for attachment to the tank,
- the tank having a foot ring,
- the foot ring having an inside surface and an outside surface,
- the foot ring extending from a bottom portion of the tank and
- operable to support the tank on a surface,
- the cover preventing the foot ring of the tank from contacting the surface;
- and
- a slit in the top portion of the cover,
- the slit having an open top and first and second opposing concentric sides extending from the open top,
- the slit sandwiching at least a portion of the foot ring of the tank where the first side slit of the silt is disposed adjacent the inside surface and the second side of the slit is disposed adjacent the outside surface when the foot ring is disposed in the slit, wherein
- the top portion extending from an inside wall to an outside wall of the cover,
- the top portion defining at a planar upwardly facing top surface,
- the entirety of the upwardly facing top surface defining a first plane parallel with a second plane of a bottom surface of the cover.
A cover for a base of a propane cylinder comprising:
- a hoop base having an inner circular perimeter and an outer circular perimeter, the hoop base having a base surface and an upper surface opposite the base surface, the inner circular perimeter and the outer circular perimeter extending concentrically from the base surface to the upper surface;
- an inner upstand extending upwardly from the upper surface of the hoop base defining an inner upstand inner wall and an inner upstand outer wall, and defining an inner thickness;
- and
- an outer upstand extending upwardly from the upper surface of the hoop base defining an outer upstand inner wall and an outer upstand outer wall, and defining an outer thickness, wherein
- the inner upstand and the outer upstand terminate to define a planar inner upwardly facing top surface and a planar outward upwardly facing top surface, wherein a first plane is defined by at least one of (1) an entirety of an inner upwardly facing top surface of the inner upstand, between the inner upstand inner wall and the inner upstand outer wall, and (2) an entirety of an outward upwardly facing top surface, between an outer upstand inner wall and an outer upstand outer wall is parallel to the base surface;
- and
- the outer upstand inner wall and the inner upstand outer wall face each other, are concentric and are spaced apart from each other so as to define a slot therebetween, with a base of the slot defined by the upper surface of the hoop base, the slot defining a minimum width and a depth.
