Abstract
A fully removable chime or valve guard that can support the container on its top, side and bottom is provided. The removable chime or valve guard provides protection if the container is dropped on its side or top. The protection provided allows the containers to pass a drop test per 49 CFR section 178.603, so the containers can be certified per 49 CFR 178.504.
Claims18
A fully removable valve guard for supporting a cylindrical container on its top, side and bottom;
- comprising:
- (1) a top part comprises:
- a top ring having a center ring line;
- and at least two posts;
- wherein
- each post is bent twice to form top, middle, and bottom sections wherein an axis of the top section of each post and an axis of the bottom section of each post are parallel or cross at an angle of ≤5 degree;
- each post comprises a flat contact extending radially inward from a top of the bottom section;
- and
- the axes of the bottom sections of the posts are on a virtual bottom ring that is smaller than the top ring, wherein the virtual bottom ring and the top ring are concentric;
- wherein a top end of each post is attached to a bottom of the top ring along the center ring line at right angles;
- and
- the posts are evenly spaced along the center ring line;
- and
- (2) a base comprises:
- a hollow cylinder having an outer surface with an outer diameter and an inner surface with an inner diameter;
- at least two tubes being smaller than the hollow cylinder;
- and a bottom covering all or part of a bottom hollow surface of the hollow cylinder;
- wherein
- the tubes are vertically connected to a top outer surface of the hollow cylinder and are spaced horizontally;
- and axes of the tubes are parallel to an axis of the hollow cylinder;
- and
- the inner diameter of the hollow cylinder is larger than an outer diameter of the cylindrical container and the outer diameter of the hollow cylinder is smaller than a diameter of the virtual bottom ring;
- wherein the cylindrical container is optionally placed in the hollow cylinder and guarded with the flat contacts, the bottom of the base, the top ring, and the posts while the top part is connected to the base by plugging the posts into the respective tubes in the base.
