Abstract
Abstract A thermometer sheath in a multiple pack comprising a continuous support foil (1) of paper on which a lower and an upper plastic foil (2 and 3) are placed, whereby the plastic foils (2, 3) are welded together and the lower plastic foil (2) is releasably attached to the support foil (1) by means of a heat sealing line (4), which delimits a number of case-shaped thermometer sheaths closed at one end, which are detachable from each other and from the support foil (1), and whereby the lower plastic foil (2) is longer than the upper plastic foil (3) thus that a flap is formed at the case orifice. A stiffening strip (5) of plastic material is positioned between the upper and the lower plastic foil (2 and 3) transversally to the longitudinal direction of the case and attached to said plastic foils (2, 3) by two opposite parts (4',4") of the heat-sealing line (4), whereby the stiffening strip (5) extends beyond the end of the upper plastic foil (3).

Claim 1
Independent Claim
403 words
A cartridge like multiple pack of thermometer sheaths comprising a plurality of such sheaths having: a continuous support foil of paper with a top edge and a bottom edge, a first thin plastic foil on said support having a top edge lying adjacent and substantially parallel to the top edge of said support and a plurality of toe portions extending towards said bottom edge, a second thin plastic foil overlying said first plastic foil, said second foil having a top edge displaced from and parallel to the top edge of said first foil and a plurality of toe portions extending toward the bottom edge of said support and substantially overlying toe portions of said first foil, a plurality of heat-seal lines transverse to the top edges of foils and support which define sides between adjoining thermometer sheaths, which also extend around and join the toe portions of said toe foils, which heat seals are effective to form severable lines between adjoining sheaths and which also serve to adhere said foils to the support foil along the line defining the side edges and toe portions of the thermometer sheaths, the displacement of the top edge of said second foil relative to the top edge of said first foil being sufficient to define an opening between said foils for insertion of a thermometer, said displacement further leaving a portion of top edge of the first plastic foil extending beyond the top edge of said second foil, thereby forming a flap to facilitate insertion of said thermometer, and a plastic stiffening strip between said first and second foils below the top edge of said second foil and running substantially parallel to the top edges of said plastic foils and support, said strip being bendable and having the ability to keep said first and second foils separated, a portion of said strip extending above the top edge of said second foil and below the top edge of said first foil and a portion of said strip extending below said top edge of said second foil, said strip being sealed in place between said first and second foils by the sealing lines which seal the entire strip to said first foil and the entire portion of the strip extending below the top edge of said second foil to the second foil, said strip being effective to facilitate insertion of a thermometer into a sheath within said cartridge-like pack.

A cartridge like multiple pack of thermometer sheaths comprising a plurality of such sheaths having: a continuous support foil of paper with a top edge and a bottom edge, a first thin plastic foil on said support having a top edge lying adjacent and substantially parallel to the top edge of said support and a plurality of toe portions extending towards said bottom edge, a second thin plastic foil overlying said first plastic foil, said second foil having a top edge displaced from and parallel to the top edge of said first foil and a plurality of toe portions extending toward the bottom edge of said support and substantially overlying toe portions of said first foil, a plurality of heat-seal lines transverse to the top edges of foils and support which define sides between adjoining thermometer sheaths, which also extend around and join the toe portions of said toe foils, which heat seals are effective to form severable lines between adjoining sheaths and which also serve to adhere said foils to the support foil along the line defining the side edges and toe portions of the thermometer sheaths, the displacement of the top edge of said second foil relative to the top edge of said first foil being sufficient to define an opening between said foils for insertion of a thermometer, said displacement further leaving a portion of top edge of the first plastic foil extending beyond the top edge of said second foil, thereby forming a flap to facilitate insertion of said thermometer, and a plastic stiffening strip between said first and second foils below the top edge of said second foil and running substantially parallel to the top edges of said plastic foils and support, said strip being bendable and having the ability to keep said first and second foils separated, a portion of said strip extending above the top edge of said second foil and below the top edge of said first foil and a portion of said strip extending below said top edge of said second foil, said strip being sealed in place between said first and second foils by the sealing lines which seal the entire strip to said first foil and the entire portion of the strip extending below the top edge of said second foil to the second foil, said strip being effective to facilitate insertion of a thermometer into a sheath within said cartridge-like pack.
Claim 3
Dependent Claim
31 words
A thermometer sheath pack according to claim 1 characterized in that the profile of each sheath is such that it tightly encloses the tip of the thermometer shoulder of the thermometer.
Claim 4
Dependent Claim
25 words
A thermometer sheath pack according to claim 1 characterized in that the stiffening strip projects beyond the upper foil to about half the width thereof.
Claim 5
Dependent Claim
30 words
A thermometer sheath pack according to claim 1 characterized in that the stiffening strip extends from the upper foil to about 1/8-1/3, preferably 1/6-1/4 of the length of the flap.
