  • Patent number: 6808066
    Abstract: A pouch for heated appliances protects external articles from damage from heat emitted from the appliance immediately after use. The present pouch is formed of inner and outer fabric sheets, with the inner sheet comprising a heat resistant synthetic material and the outer sheet comprising a durable material for wear resistance. A series of manufacturing steps results in all seams being disposed within the insulating volume between the two plies of material, with the two sheets being joined only along the open top or upper edge of the pouch in order to minimize heat transfer along any common seams. The permanently open top is secured by an adjustably positionable strap which secures between the handle and clip lever of the curling iron, with the open top providing ventilation for the heated appliance. External ties are provided for securing the appliance cord externally to the appliance, to avoid heat damage thereto.

  • Patent number: 6416452
    Abstract: A method of making multiwall plastic bags wherein half-width foil webs are unwound from respective rolls below a segment of a path within which a multilayer full-width web is guided. The half-width webs can be slit and unfolded or simply unfolded to form full-width single-layer webs which are combined by superimposition to form the multilayer full-width web. The latter is folded and the folded multilayer width is formed into the bags.

  • Patent number: 6110091
    Abstract: There is provided a nurser liner having a pair of removable textured tabs for mounting the nurser liner to the rim of a nurser container. The tabs have a textured surface formed by piercing and embossing with forming tools. Each tab has a plurality of pierced holes that go through the tab to form an improved surface for gripping and handling. Each tab also has a plurality of embossed areas that supplement the pierced holes to improve gripping and handling while minimizing wear to the forming tools. In addition, the tabs may have a three segment pattern such that a smooth, non-textured center portion is located between textured portions on either side of the center portion. Accordingly, the combination of pierced and embossed areas provides the gripping advantages of pierced tabs while minimizing the amount of wear caused to the forming tools.

  • Patent number: 5647832
    Abstract: An apparatus for manufacturing a liner having baffles therein for use inside of a flexible bulk container, having a frame supporting a first feed means mounted adjacent to a feed path for feeding a sheet of liner material over the feed path at a first speed. A second feed means is mounted adjacent the feed path between the first feed means and a finishing end of the feed path for feeding a length of ribbon material over the feed path adjacent the sheet of liner material at a second speed. An attachment means is mounted adjacent the feed path for attaching the fed ribbon material to the fed sheet of liner material at spaced apart intervals. A cutter is mounted adjacent the feed path and between the attachment means and the finishing end for cutting a predetermined length of liner material having first and second ends. A folder folds the cut length of liner material in half along a fold line perpendicular to the longitudinal axis of an attached length of ribbon, such that the ribbon is inside of the fold.
