Abstract
Abstract A telescopic drinking straw in which a first elongated tubular cylinder has a second tubular cylinder slidably disposed therein. The first cylinder and the second cylinder are provided with annular flanges which retain the ends of a coil spring disposed over the cylinders. The spring forces the second cylinder vertically upward out of the first cylinder when the cap of a container in which the straw is packaged is removed, thereby making the straw available to the user for drinking of the liquid in the container. The outer cylinder of the drinking straw may also be provided with a plurality of slots at a particular point along its length. One end of the telescopic outer portion is affixed to the inner section of the straw, so that when the outer section is compressed downwardly to be packaged into a bottle, the portion containing the slots will extend outwardly and act as a spring forcing the outer telescopic section against the inner surface of the container cap. When the cap is removed, the extended portions contract inwardly, forcing the telescopic section out of the container.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
108 words
A telescopic drinking straw, comprising; a first elongated tubular cylinder, a second elongated tubular cylinder, having a diameter less than the diameter of said first cylinder, slidably disposed within said first cylinder, retaining means rigidly affixed to the exterior surfaces of said first and second cylinders, and spring means, disposed about said first and second cylinders, and secured by said retaining means, for exerting oppositely directed forces on said retaining means and said first and second cylinders so that said second cylinder is ejected from said first cylinder and the neck of the container in which the straw is packaged when the cap of the container is removed.
Claim 2
Dependent Claim
108 words
A telescopic drinking straw, comprising; a first elongated tubular cylinder, a second elongated tubular cylinder, having a diameter less than the diameter of said first cylinder, slidably disposed within said first cylinder, retaining means rigidly affixed to the exterior surfaces of said first and second cylinders, and spring means, disposed about said first and second cylinders, and secured by said retaining means, for exerting oppositely directed forces on said retaining means and said first and second cylinders so that said second cylinder is ejected from said first cylinder and the neck of the container in which the straw is packaged when the cap of the container is removed.
Claim 3
Dependent Claim
112 words
The telescopic drinking straw as recited in claim 1 further comprising abutment means rigidly affixed to the interior wall of said first cylinder at one end thereof, and wherein said second cylinder includes a first portion having a diameter substantially smaller than said first cylinder which is slidable between said abutment means, and a second portion having a diameter slightly smaller than that of said first cylinder for providing a snug fit within said first cylinder and comprising one end of said second cylinder, for engaging said abutment when said second cylinder is ejected from said first cylinder and thereby limiting the outward movement of said second cylinder from said first cylinder.
Claim 4
Dependent Claim
56 words
The telescopic drinking straw as recited in claim 2, wherein said retaining means comprises first and second annular flanges rigidly affixed to the exterior surfaces of said first and second cylinders respectively, defining a pair of annular recesses around said cylinders opening inwardly towards each other along the longitudinal axes of said first and second cylinders.
Claim 5
Dependent Claim
38 words
The telescopic drinking straw as recited in claim 3, wherein said spring means is a coil spring disposed over said first and second cylinders having its ends disposed in said first and second annular flanges on said cylinders.
Claim 6
Dependent Claim
117 words
A telescopic drinking straw, comprising; a first elongated tubular cylinder, a second elongated tubular cylinder, having a diameter smaller than that of said first cylinder, slidably disposed within said first cylinder, retaining means affixed to the exterior surface of said first cylinder at one end thereof, and spring means disposed over the end of said first cylinder so as to engage said retaining means and the bottom surface of the container in which the straw is packaged, for ejecting said first and second cylinders out of the container when the cap of the container is removed and thereby allowing said second cylinder to be manually withdrawn from said first cylinder for drinking the liquid in the container.
Claim 7
Dependent Claim
117 words
A telescopic drinking straw, comprising; a first elongated tubular cylinder, a second elongated tubular cylinder, having a diameter smaller than that of said first cylinder, slidably disposed within said first cylinder, retaining means affixed to the exterior surface of said first cylinder at one end thereof, and spring means disposed over the end of said first cylinder so as to engage said retaining means and the bottom surface of the container in which the straw is packaged, for ejecting said first and second cylinders out of the container when the cap of the container is removed and thereby allowing said second cylinder to be manually withdrawn from said first cylinder for drinking the liquid in the container.
Claim 8
Dependent Claim
114 words
The telescopic straw as recited in claim 5 further comprising abutment means affixed to the interior surface of said first cylinder at one end thereof, and wherein said second cylinder includes a first portion having a diameter substantially less than that of said first cylinder which is slidable between said abutment means, and a second portion having a diameter slightly less than that of said first cylinder for providing a snug fit within said first cylinder and comprising an end portion of said second cylinder, for engaging said abutment means when said second cylinder is withdrawn from said first cylinder and thereby limiting the outward movement of said second cylinder from said first cylinder.
Claim 9
Dependent Claim
51 words
The telescopic drinking straw as recited in claim 6, wherein said retaining means comprises an annular flange affixed to the exterior surface of said first cylinder at the Lower end thereof which defines an annular recess around said cylinder opening downwardly along the longitudinal axes of said first and second cylinders.
Claim 10
Dependent Claim
51 words
The telescopic drinking straw as recited in claim 7, wherein said spring means is a coil spring disposed over one end of said first cylinder, having one end retained in said annular flange and the other end thereof abutting the bottom surface of the container in which the straw is packaged.
Claim 11
Dependent Claim
116 words
A telescopic drinking straw, comprising; a first elongated tubular cylinder, a second elongated tubular cylinder having a diameter smaller than that of said first cylinder, slidably disposed within said first cylinder, retaining means affixed to the exterior surface of said first cylinder at a selected point thereon, and elongated, flexible spring bands formed by a plurality of elongated slots cut in said first cylinder, said bands being forced outwardly when said first cylinder is compressed downwardly over said second tubular cylinder, for ejecting said first cylinder out of the container when the cap of the container is removed and thereby allowing said first cylinder to be manually extended from the container for drinking the liquid therein.
Claim 12
Dependent Claim
116 words
A telescopic drinking straw, comprising; a first elongated tubular cylinder, a second elongated tubular cylinder having a diameter smaller than that of said first cylinder, slidably disposed within said first cylinder, retaining means affixed to the exterior surface of said first cylinder at a selected point thereon, and elongated, flexible spring bands formed by a plurality of elongated slots cut in said first cylinder, said bands being forced outwardly when said first cylinder is compressed downwardly over said second tubular cylinder, for ejecting said first cylinder out of the container when the cap of the container is removed and thereby allowing said first cylinder to be manually extended from the container for drinking the liquid therein.
Claim 13
Dependent Claim
52 words
The telescopic drinking straw as recited in claim 9, wherein said retaining means comprises an annular flange affixed to the exterior surface of said second cylinder at the lower end thereof, said flange defining an annular recess around said cylinder opening upwardly along the longitudinal axes of said first and second cylinder.
