Abstract

Abstract A fabric cover for a steam pack used as a compress to apply localized moist heat to the human body includes a sheet of flexible material adapted to at least partially enclose the steam pack and having a plurality of snap fastening devices arranged to enable either side of the sheet to be folded over and fastened together at its marginal edges to cover the pack, or alternatively to cooperate with a similar cover to enclose a larger size pack therebetween where either side of one cover may be fastened along its marginal edges to either side of the other cover. A first pair of the snap fastening devices are arranged at the marginal edges of the sheet and have male members extending from one face of the sheet and having female members axiallyaligned with and connected through the sheet to the male members extending from the opposite face of the sheet. A second pair of snap fastening devices arranged at marginal edges of the sheet have male members extending from the same side of the sheet as the foregoingmentioned female members for snapping into engagement therewith and have female members extending from the opposite side of the sheet in axial alignment with and connected through the sheet to the last-mentioned male members to snap into engagement with the first-mentioned male members, whereby the cover is reversible to eliminate unwanted time-consuming manipulations of the cover when enclosing a heated steam pack. Each snap fastening device includes a male member having a stem and a base flange adapted to engage one face of the fabric material, and a retaining ring having a plurality of axiallyextending depending prongs adapted to surround the stem of the male member with the prongs extending through holes in the base flange and through the fabric material for being retained in an in-turned annular flange at the back side of a female member.

Claim 1
Independent Claim 188 words
A cover for a steam pack, comprising: a sheet of flexible material adapted to at least partially enclose the steam pack and having a plurality of snap fastening devices, first and second ones of said devices being arranged at marginal edges of said sheet, each one of said first and second devices having a male member extending from one face of said sheet and having a female member axially aligned with and connected through said sheet to said male member and extending from the opposite face of said sheet; and third and fourth ones of said devices being arranged at marginal edges of said sheet, each one of said third and fourth devices having a male member extending from said opposite face of said sheet and adapted to snap into engagement with one of said female members of said first and second devices and having a female member extending from said one face of said sheet in axial alignment with and connected through said sheet to the last-mentioned male member and adapted to snap into engagement with one of said male members of said first and second devices.
Claim 2
Dependent Claim 188 words
A cover for a steam pack, comprising: a sheet of flexible material adapted to at least partially enclose the steam pack and having a plurality of snap fastening devices, first and second ones of said devices being arranged at marginal edges of said sheet, each one of said first and second devices having a male member extending from one face of said sheet and having a female member axially aligned with and connected through said sheet to said male member and extending from the opposite face of said sheet; and third and fourth ones of said devices being arranged at marginal edges of said sheet, each one of said third and fourth devices having a male member extending from said opposite face of said sheet and adapted to snap into engagement with one of said female members of said first and second devices and having a female member extending from said one face of said sheet in axial alignment with and connected through said sheet to the last-mentioned male member and adapted to snap into engagement with one of said male members of said first and second devices.
Claim 3
Dependent Claim 103 words
A cover according to claim 1, wherein each one of said snap fastening devices includes a male member having a stem and a base flange engaging said sheet and having a plurality of holes extending through said flange, a retaining ring having a plurality of depending prongs surrounding said stem with said prongs extending through said holes and through aligned holes in said sheet, a female member having a male-member receiving receptacle on one side thereof and having an inwardly-turned annular flange on its other side thereof for engaging the sheet and for receiving and retaining the distal end portions of said prongs.
Claim 4
Dependent Claim 59 words
A cover according to claim 2, wherein each one of the stems of the male members having an external annular recess disposed adjacent said annular member, each one of the receptacles of said female members being in the form of a tubular member having a plurality of resilient in-turned fingers for gripping one of said stems in its recess.
Claim 5
Dependent Claim 41 words
A cover according to claim 3, wherein each one of said retaining rings includes an annular member, said prongs extending from said annular member in a direction parallel to the axis of said annular member and being spaced from said axis.
