Abstract

294,187. Hutt, A. C. April 20, 1927. Tubes or containers, collapsable. -Relates to collapsable containers of the kind which are provided with a stiff outer casing, in order to avoid the shapeless and unsightly appearance of the container when partially empty. In the form shown in Fig. 1, the container is of annular crosssection, having a rigid outer wall 10 and a collapsable inner wall 11, between which the material is enclosed. The inner wall is corrugated longitudinally, and can be distended outwardly towards the outer wall by means of a follower 14, in order to expel the material. A container of this form, having both walls collapsable, may be held in a stiff outer casing 19, Fig. 4, formed with a bulge 20, into which the outer wall of the container is forced when pressure is applied, so as to lock the two parts of the device together. A collapsable container 21, Fig. 5, of bellows form is provided with a deformable rib 22, which can be pressed into a groove at the upper end of a stiff outer casing 24. The container may comprise a flanged body part 25, Fig. 8, and a separate end-member 27, which can rest upon a shoulder 29 on a stiff outer casing 28. The rim of the casing is then turned over, so as to clamp the parts together. The collapsable container may be of telescopic form.
