Abstract

Abstract A hygienic protective shield, as seat shield, protecting glove, shield for thermometers or other temperature sensing devices and shields for other instruments, which shield comprises two adjacent plastic foils, attached to each other to form a space for receiving and enclosing an object, at least two covering foils attached on each side of the two-layer plastic foils, and two stiffening plastic strips arranged to overlap th covering foils. The shield can be packed in sterile condition and remains sterile until the movement when used thereby avoiding contamination.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 318 words
An hygienic protecting shield for an object, such as a seat shield, a protecting glove, a shield for a thermometer or other temperature sensing devices, and a shield for other instruments, which shield comprises: two adjacent plastic foils at least one of which is at least the same length as the part of the object to be received in the shield; at least one covering foil arranged on the outside of each of the two plastic foils to form at least four foil layers, the covering foils being shorter than the plastic foils and further arranged thereon to expose one end of the plastic foils; means removably attaching each covering foil to the adjacent plastic foil and sealing the plastic foils to each other along a line defining an object-receiving space between the plastic foils which is a least partly cut off from the remaining parts of the plastic foils and has an opening for receiving the object at the exposed end of the plastic foils, the attaching and sealing means being spaced inwardly from at least a portion of an edge of the foils which is sufficiently close to the exposed end of the plastic foils and adapted in combination with the covering foils for facilitating a sidewise tearing of the object-receiving part of the plastic foils from the covering foils and the remainder of the plastic foils; and a stiffening strip on the exposed end of each plastic foil which overlaps the corresponding covering foil, whereby the object-receiving part of the plastic foils is covered with the covering foils and stiffening strips until the shield is used to prevent contamination thereof and, for use, the object can be inserted between the stiffening strips into the object-receiving space between the plastic foils and the stiffening strip and the end portion of the shield then grasped and easily separated to provide an hygienic foil shield about the object.
Claim 2
Dependent Claim 318 words
An hygienic protecting shield for an object, such as a seat shield, a protecting glove, a shield for a thermometer or other temperature sensing devices, and a shield for other instruments, which shield comprises: two adjacent plastic foils at least one of which is at least the same length as the part of the object to be received in the shield; at least one covering foil arranged on the outside of each of the two plastic foils to form at least four foil layers, the covering foils being shorter than the plastic foils and further arranged thereon to expose one end of the plastic foils; means removably attaching each covering foil to the adjacent plastic foil and sealing the plastic foils to each other along a line defining an object-receiving space between the plastic foils which is a least partly cut off from the remaining parts of the plastic foils and has an opening for receiving the object at the exposed end of the plastic foils, the attaching and sealing means being spaced inwardly from at least a portion of an edge of the foils which is sufficiently close to the exposed end of the plastic foils and adapted in combination with the covering foils for facilitating a sidewise tearing of the object-receiving part of the plastic foils from the covering foils and the remainder of the plastic foils; and a stiffening strip on the exposed end of each plastic foil which overlaps the corresponding covering foil, whereby the object-receiving part of the plastic foils is covered with the covering foils and stiffening strips until the shield is used to prevent contamination thereof and, for use, the object can be inserted between the stiffening strips into the object-receiving space between the plastic foils and the stiffening strip and the end portion of the shield then grasped and easily separated to provide an hygienic foil shield about the object.
Claim 3
Dependent Claim 37 words
Hygienic shield according to claim 1 characterized in that a number of hygienic shields are removably attached to each other by means of a perforation (13) along sides of the foils to form a band of shields.
Claim 4
Dependent Claim 48 words
An hygienic shield according to claim 1 further characterized in that one plastic foil is shorter than the other at the exposed end of the plastic foils and the covering foils are shorter than the shorter of the plastic foils to expose an end of both plastic foils.
Claim 5
Dependent Claim 38 words
An hygienic shield according to claim 1 further characterized by means for sealing the covering and the plastic foils to each other outside the object-receiving space and at an end opposite the exposed end of the plastic foils.
Claim 6
Dependent Claim 30 words
An hygienic shield as in claim 1 further characterized in that the stiffening strips are fixed on the respective plastic foils only at edges of the foils and stiffening strips.
Claim 7
Dependent Claim 245 words
An hygienic protecting shield for a thermometer, the shield comprising: two adjacent plastic foils at least as long as the part of the thermometer to be received in the shield; a covering paper foil arranged on the outside of each of the two plastic foils to form four foil layers, the paper covering foils being shorter than the plastic foils and further arranged thereon to expose one end of the plastic foils; a heat seal removably attaching each paper covering foil to the adjacent plastic foil and sealing the plastic foils to each other along a line for defining an object-receiving space between the plastic foils which is completely cut off from the remaining parts of the plastic foils and has an opening thereto for receiving the thermometer at the exposed end of the plastic foils, the heat seal line being spaced inwardly from a substantial portion of an edge of the foils adjacent the exposed end of the plastic foils to facilitate, in combination with the covering paper foils, sidewise tearing of the object-receiving part of the plastic foils from the paper covering foils and the remainder of the plastic foils; and a plastic stiffening strip on the exposed end of each plastic foils which overlaps the corresponding paper covering foil to prevent, in combination with the paper covering foils, contamination of the plastic foils until the thermometer is inserted in the object-receiving space and the shield torn from the remainder of the foils.
Claim 8
Dependent Claim 245 words
An hygienic protecting shield for a thermometer, the shield comprising: two adjacent plastic foils at least as long as the part of the thermometer to be received in the shield; a covering paper foil arranged on the outside of each of the two plastic foils to form four foil layers, the paper covering foils being shorter than the plastic foils and further arranged thereon to expose one end of the plastic foils; a heat seal removably attaching each paper covering foil to the adjacent plastic foil and sealing the plastic foils to each other along a line for defining an object-receiving space between the plastic foils which is completely cut off from the remaining parts of the plastic foils and has an opening thereto for receiving the thermometer at the exposed end of the plastic foils, the heat seal line being spaced inwardly from a substantial portion of an edge of the foils adjacent the exposed end of the plastic foils to facilitate, in combination with the covering paper foils, sidewise tearing of the object-receiving part of the plastic foils from the paper covering foils and the remainder of the plastic foils; and a plastic stiffening strip on the exposed end of each plastic foils which overlaps the corresponding paper covering foil to prevent, in combination with the paper covering foils, contamination of the plastic foils until the thermometer is inserted in the object-receiving space and the shield torn from the remainder of the foils.
