Collapsible expansible plastic hollow articles in a latchable configuration
First Claim
1. A collapsible and expandable plastic hollow article comprising:
- a top (101) and a base (102) joined by a substantially cylindrical side wall (103) having an axis and being integral with said top and said base and an aperture (104) in the top (101), said side wall comprising a plurality of substantially circular bellows (105, 105'"'"') formed by conical sections (106,
107) integrally joined to create at least a portion of said side wall (103), the conical sections (106,
107) comprising alternating short portions (107) and long portions (106), said short portions being at a greater angle to said axis than said long portions, said short portions joining with said long portions to form alternately junctures of greater and lesser diameters, the lesser diameter junctures (108) of the long portions (106) joining with the short portions (107) being formed to create fold rings (109, 109'"'"') for the substantially circular bellows; and
connecting means for connecting a suction cup to said base, said connecting means being adapted for transferring an axially upwardly force exerted on said hollow article to said suction cup, so that in use the suction cup holds the base upon expansion of said hollow article.
