1 Claim. (Cl. 206-46) This invention relates to a new and improved shockproof package.

It has heretofore been proposed to provide a package in which a frangible article is held in a plastic tube, which is twisted tight above and below the article, strains being taken by the resiliency of the plastic tube.

It is an object of this invention to provide a package of the general character above described, which will be simpler and cheaper in construction, and more rigid in use. The invention accordingly comprises the articles hereinafter described and shown in the accompanying drawings, in which:

Fig. 1 is an exploded view;

Fig. 2 is a section of the line 2-2 of Fig. 3;

Fig. 3 is a section of the line 33 of Fig. 2;

As herein illustrated, the outer casing may be a cylindrical tube of fiber-board, which may be closed at each end by a cap 12. A plastic tube 13 which may be of a somewhat smaller diameter than the casing 10, has each end wrapped around and attached to a separate ring 14, 14a of a size to fit within casing 10.

This plastic tube is somewhat longer than the casing 10 as will be hereinafter understood. Within the casing 10 there is carried a polygonal frame, or tube, 15 of a size to fit snugly within the casing 10, and one side of this casing may be slit as shown at 16, so that it may be shipped and handled as a flat sheet.

The device is assembled by inserting the bottom ring 14 with the plastic tube attached, within the casing 10. The polygonal frame 15 is then folded about the plastic tube above the bottom ring and it is pressed down inside "ice the casing 10. The top ring 14a may now be turned until the plastic tube is brought together near the bottom to close it by the twist, as shown at 17 in Fig. 3. The package is now in position to receive the article to be packed above the twist. Thereafter the ring 14 may be inserted into the top of the casing above the top of frame 15 and twisted until the plastic tube is brought together also above the article, as shown at 18. This twisting is continued until the tube is brought under tension. It will be seen that the polygonal frame 15 serves to hold the rings 14 and 14a spaced from each other, and hence to maintain the tube under the tension resulting from the twisting. The parts are retained by friction to prevent the untwisting of the tube. The caps 11 and 12 may be then inserted over the tube, and it is ready for shipping.

From the above construction, it will be seen that all parts of this container may be made from standard parts without special forming, and hence the package itself may be made with a minimum of expense.

What I claim is:

A shock-proof container comprising a tubular member of polygonal cross section, a pair of rings having approximately the same diameter as said tubular member and each rotatably supported on an end of said member, a plastic tube member within said polygonal member having its ends extending through and down over the outside of said rings and secured thereto, the plastic tube being adapted to contain an article and being of a length to permit it being twisted together above and below the article thereby to enclose and support the same, an outer casing for supporting and holding said members in alignment, and means :closing each end of the casing.
