Abstract
A limited durability fastening for a garment. The garment is provided with fastening members which engage to close the fastening and the fastening members are provided with means for controlling the degradation of the closure strength of the fastening as it is opened and closed and thus the number of permissible closures of the fastening having a pre-determined closure strength. The garment is particularly useful when fitted to a foot where short life is desirable at low cost or to a garment where re-use is to be discouraged for either clinical or commercial reasons.
Claims7
A limited durability fastening for a garment comprising at least two garment elements to be fastened together with a predetermined closure strength, each garment element being provided with a fastening member which members engage to close the fastening, and means for controlling the degradation of the closure strength of the fastening as it is opened and closed and thus the number of permissible closures of the fastening having a predetermined closure strength, wherein one fastening member is an adhesive tab, the other fastening member being made of a fibrous material which degrades the contact strength of the fastening by transfer of fibrous material to the adhesive tab upon repeated make and break closure contact, and means applied to the fibrous material to control fibrous transfer of material in the area of make and break contact and thus the closure strength of the fastening, wherein said control means applied to said material is in the form of a separate filmic layer attached to said material.
A limited durability fastening for a garment comprising at least two garment elements to be fastened together with a predetermined closure strength, each garment element being provided with a fastening member which members engage to close the fastening, and means for controlling the degradation of the closure strength of the fastening as it is opened and closed and thus the number of permissible closures of the fastening having a predetermined closure strength, wherein one fastening member is an adhesive tab, the other fastening member being made of a fibrous material which degrades the contact strength of the fastening by transfer of fibrous material to the adhesive tab upon repeated make and break closure contact, and wherein the control means is applied to said fibrous material and is in the form of contrasting coloured dots so that a level of closure strength degradation of the fastening may be determined by contrasting coloured contamination of the adhesive tab.
