Abstract
A scuff type slipper is produced so economically that it may be disposable, yet it has excellent cushioning properties and a sole with sufficient stiffness that the heel end will not fold under when in use. The slipper is produced from third web cushioning material. This has two planar thermoplastic webs spaced apart from one another by a middle thermoplastic web in the form of a plurality of bubbles hermetically sealed to the outer webs, trapping gas in the bubbles for cushioning and imparting stiffness. A vamp portion is formed by folding over a strip of the material at the toe end and fusion bonding it along the sides to the sole of the slipper and then cutting the slipper from the strip.
Claims8
A slipper comprised of a sole portion and a vamp portion attached to the sole portion, both portions being formed of
- a material having a substantially planar thermoplastic top web and a substantially planar thermoplastic bottom web spaced apart by a thermoplastic middle web, the middle web being in the form of a plurality of bubbles bonded to the top and bottom webs so that the bubbles are hermetically sealed, trapping gas therein, the material thereby having a cushioning property from the bubbles and a stiffness property from the spaced apart top and bottom webs, said stiffness property being sufficient to prevent said sole portion from folding under in use.
A scuff slipper comprising:
- A) a sole portion with toe and heel ends and elongate side edges, the sole portion being of a material having a substantially planar thermoplastic top web and a substantially planar thermoplastic bottom web spaced apart by a thermoplastic middle web, the middle web being in the form of a plurality of bubbles bonded to the top and bottom webs so that the bubbles are hermetically sealed, trapping gas therein, the material thereby having a cushioning property from the bubbles and a stiffness property from the spaced apart top and bottom webs, said stiffness property being sufficient to prevent said sole portion from folding under in use;
- and
- B) a vamp portion attached to the toe end of the sole portion and extending part way to the heel and of the sole portion, the vamp being attached also to the side edges if the sole portion.
