701,423. Collapsible tubes. WEINSTEIN. P. S., and JOUKOVSKY, S. Feb. 6, 1952, No. 3140/52. Class 66 A collapsible tube container for viscous material consists of a tubular body 1 with a closure member such as a screw on cap 5 secured by chain 6 at one end and left open at the opposite end 2 In this outer body may be placed a deformable inner container 7, the top fiap-like extensionbeing removed along the line 9 before its insertion and the end 2 of the body then closed by a temporary closing means in such manner as to keep it closed against pressure applied to eject a portion of the material through the nozzie 3 of the tube. When the container is empty a new inner container 7 may be inserted in place of the one. emptied. The outer body may be made of flexible sheet material such as plastic (e.g. polyethylene, nylon, polyvinyl chloride or polyvinyl acetate), rubber or treated fabric. The inner container may have relatively low tensile strength and be made of similar plastic material, "Cellophane" (Registered Trade Mark), or waterproofed paper or fabric. The temporary closing means may consist of a bar or rod 13 permanently attached to a flap 12 extending from one side of the bottom of the tube around which the flap and end of the tube may be wound and secured by a clamp member passing through a hole in the end of the bar, Figs. 5 and 6 (not shown), or by a separate spring clamp member 16. A different closing means consists of a resilient fork-like clip 18 which has an open-ended pivoted locking clamp at one end, Fig. 9 (not shown), or a closed locking clamp 19 having cylindical portion 20 which may be sprung into retaining notches 21 in the end of the legs of clip 18.
