Abstract
Abstract A protective holder adapted to be positioned proximate the circular neck of a filter-type coffee maker having bowed-in side walls. The holder includes a pair of planar portions each having a concave inner margin. These two portions are joined adjacent their respective concave inner margins and mating fasteners are fastened to these two portions so that the holder can be secured in position about the neck of the coffee maker. The radius of curvature of the joined concave inner margins is selectively chosen to be substantially larger than the radius of curvature of the circular neck of the coffee maker so that when the holder is fitted about the neck of the coffee maker, the two portions of the holder will automatically be displaced from their storage position wherein they are substantially parallel, to their use position wherein they will engage the bowed-in side walls of the coffee maker proximate the neck thereof.

A protective holder adapted to be positioned proximate the circular vertex of a filter-type coffeemaker having bowed-in side walls comprising a pair of planar surface engaging elements each including a concave inner margin, means for joining said pair of planar surface engaging elements adjacent their respective inner concave margins. the radius of curvature of said concave inner margins of said planar surface engaging elements being substantially larger than the radius of curvature of the circular vertex of the filter-type beverage maker on which it is adapted to be mounted whereby said pair of planar elements can be positioned in substantially overlapping parallel relation with the radius of curvature of the joined inner margins is equal to the radius of curvature of the inner margin of each of said planar elements and said pair of planar elements can be automatically angularly displaced away from each other about said joined inner margins into engagement with the bowed-in walls of the beverage maker when the protective holder is placed in position proximate the circular vertex of the coffeemaker and the radius of curvature of said joined marginal edges is reduced to the radius of curvature of the vertex of the coffeemaker, and fastening means for securing said protective holder in position about the circular vertex of the filter-type coffeemaker.
Claim 2
Dependent Claim
216 words
A protective holder adapted to be positioned proximate the circular vertex of a filter-type coffeemaker having bowed-in side walls comprising a pair of planar surface engaging elements each including a concave inner margin, means for joining said pair of planar surface engaging elements adjacent their respective inner concave margins. the radius of curvature of said concave inner margins of said planar surface engaging elements being substantially larger than the radius of curvature of the circular vertex of the filter-type beverage maker on which it is adapted to be mounted whereby said pair of planar elements can be positioned in substantially overlapping parallel relation with the radius of curvature of the joined inner margins is equal to the radius of curvature of the inner margin of each of said planar elements and said pair of planar elements can be automatically angularly displaced away from each other about said joined inner margins into engagement with the bowed-in walls of the beverage maker when the protective holder is placed in position proximate the circular vertex of the coffeemaker and the radius of curvature of said joined marginal edges is reduced to the radius of curvature of the vertex of the coffeemaker, and fastening means for securing said protective holder in position about the circular vertex of the filter-type coffeemaker.
Claim 3
Dependent Claim
15 words
A protective holder according to claim 1 wherein said fastening means comprises a VELCRO fastener.
Claim 4
Dependent Claim
24 words
A protective holder according to claim 2, wherein said pair of planar elements include vinyl outer layers and an intermediate layer of insulating material.
Claim 5
Dependent Claim
