Patent number: 5506019Abstract: A table cover for covering a top surface and open side areas of a table. The inventive device includes a top cover web having opposed top cover longitudinal edges thereof placable over the top surface of an associated table structure. A first side drape web is coupled to a first edge of the top cover so as to hang downwardly therefrom to cover a first open side area of the table. A second side drape web is similarly coupled to a second edge of the top cover to hang downwardly therefrom to cover a second open side area of the table. The table cover is formed by a process resulting in an inherent placement of the table cover in a folded condition for rolling into a supply roll, whereby a suitable length of the table cover can be dispensed from the roll and cut to fit a particular length of the associated table. The table cover is preferably formed of contrastingly colored webs and may additionally include a valance extending along a juncture of the first side web and the top cover web.Type: GrantFiled: September 29, 1994Date of Patent: April 9, 1996Inventors: Joseph T.

Patent number: 4744118Abstract: A fitted sheet for covering a standard crib or bed mattress. The fitted sheet is developed from a single rectangular blank of non-woven fabric material, the sides of which are folded in along parallel longitudinal fold lines to form a folded-in sheet whose width corresponds to that of the mattress for which it is intended and whose length exceeds that of the mattress to an extent necessary to define the ends of the fitted sheet. Each corner of the folded-in sheet is seamed along a diagonal line to form a triangular flap which when the sides of the folded-in sheet are folded over the sides of the mattress, then defines a right angle corner that fits against the corresponding corner of the mattress. Each end of the fitted sheet is rendered stretchable by an elastic strip whereby the fitted sheet conforms snugly to the mattress.Type: GrantFiled: May 4, 1987Date of Patent: May 17, 1988Inventor: Audrey T. Lunt

Patent number: 4704753Abstract: A fitted sheet for covering a standard crib or bed mattress, the sheet being made of synthetic plastic material having an absorbent top layer laminated to a liquid-impermeable backing film whereby when a crib or bed occupant wets the sheet, the liquid is absorbed thereby, yet the underlying mattress is maintained in a dry, sanitary condition. The fitted sheet is created from a single rectangular blank whose sides are folded in on longitudinal fold lines and whose ends are folded in on transverse fold lines, the corners of the blank being folded in on diagonal fold lines to form triangular folds that are ultrasonically sealed to the folded-in ends, thereby defining a box-like fitted sheet having reinforced right angle corners and sides and ends coextensive with those of the mattress. Each end of the fitted sheet is creased to form puckers that are joined to an elastic strip to render the end stretchable whereby the fitted sheet conforms snugly to the mattress.Type: GrantFiled: November 20, 1986Date of Patent: November 10, 1987Inventor: Audrey T.

Patent number: 4627426Abstract: A highly absorbent sheet or pad sized to and placed onto the top of an operating table is weakened longitudinally through the center to form paired separable center-joined sections for lateral removal to respective sides of a patient lying on the sheet and centered longitudinally therewith. After surgery, the absorbent pad carrying a significant mass of blood can be quickly removed from the patient by pulling with sufficient force on the opposites sides of the pad, severing the pad centrally at the weakened portion. The weight of the patient tends to maintain one section of the pad beneath that portion of the patient as the other section is torn laterally away from the one section. The pad may comprise several layers with one or more layers being weakened by thinning the sheet material or perforating the same longitudinally.Type: GrantFiled: May 17, 1985Date of Patent: December 9, 1986Assignee: American Industrial Research, In.Inventors: Jack Wegener, Raynor A.

Patent number: 4606964Abstract: A bulked web composite comprises a differentially tensioned reticulated web of elastic material bonded to at least one gatherable web whereby, upon release of the tensioning forces, the gatherable web or webs are gathered by the reticulated web with different degrees of bulking in different areas due to the different tension levels of the reticulated web. Also disclosed is a method of making a bulked web composite by the steps of: forming a reticulated web of elastic material and elongating at least portions of the web by differentially tensioning it, and bonding the differentially tensioned web to at least one gatherable web to form a composite. The composite is then relaxed whereby portions of the gatherable web are gathered by the contracted reticulated web with different degrees of bulking in different areas. Bulked web composites of such type may be employed to form disposable swim wear, towels, wash cloths, and the like.Type: GrantFiled: November 22, 1985Date of Patent: August 19, 1986Assignee: Kimberly-Clark CorporationInventor: Ronald H.

Patent number: 4596618Abstract: Disposable fitted sheets and method for making them. The sheets are formed without necessitating prior cutting by folding edges of the material and attaching the folded-over edges along diagonal lines associated with each corner. Elastic bands cooperate with each pocket to maintain the fit on the corners of the mattress. The bands are fastened in a stretched condition to the folded-over edges while the sheet is in a flat state. The process of the invention is particularly adapted to continuously forming such sheets which may be formed from a variety of inexpensive materials. Sheets of the invention are particularly useful in hospitals and nursing homes where frequent bedding changes may be needed.Type: GrantFiled: February 16, 1984Date of Patent: June 24, 1986Assignee: Kimberly-Clark CorporationInventor: Philip G.

Patent number: 4524474Abstract: An absorption pad useful for protecting a bed, furniture, or the like, includes a lower liquid impervious material layer and an upper liquid absorbent material layer laminated thereto. The liquid absorbent layer is impregnated with strings or filaments of a liquid resistant agent which does not stiffen the pad. The strings or filaments form a grid-like pattern for defining compartments between the strings over preferably the entire area of the absorption pad, thereby for limiting the spread of liquid over the pad. The layers are laminated together, and may be laminated by an adhesive. The laminating areas may be in a filament pattern corresponding to and overlapping the filament pattern of the strings of the liquid resistant agent.Type: GrantFiled: April 26, 1983Date of Patent: June 25, 1985Assignee: Duni Bila ABInventor: Sven A.
