Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
173 words
A removable and replaceable cover for a container such as an aerosol container having a domed roof, a circular collar having an undersurface located above said domed roof and surrounding a dispensing actuator, said cover including: a top wall, a relatively thin flexible outer sleeve depending from said top wall, a relatively thin flexible inner sleeve generally coaxial with said outer sleeve and also depending from said top wall, an inwardly projecting distortable locking flange carried by said inner sleeve and adapted to engage the undersurface of said circular collar of said container when said cover is installed on said container, at least one slit formed in said inner sleeve and extending through said locking flange to allow distortion of said locking flange, and a plurality of ribs connecting said inner and outer sleeves to transmit forces applied to said outer sleeve between said sleeves, said ribs being spaced around the periphery of said inner sleeve so as to cause distortion of said locking flange upon the transmission of forces between said sleeves.
Claim 2
Dependent Claim
173 words
A removable and replaceable cover for a container such as an aerosol container having a domed roof, a circular collar having an undersurface located above said domed roof and surrounding a dispensing actuator, said cover including: a top wall, a relatively thin flexible outer sleeve depending from said top wall, a relatively thin flexible inner sleeve generally coaxial with said outer sleeve and also depending from said top wall, an inwardly projecting distortable locking flange carried by said inner sleeve and adapted to engage the undersurface of said circular collar of said container when said cover is installed on said container, at least one slit formed in said inner sleeve and extending through said locking flange to allow distortion of said locking flange, and a plurality of ribs connecting said inner and outer sleeves to transmit forces applied to said outer sleeve between said sleeves, said ribs being spaced around the periphery of said inner sleeve so as to cause distortion of said locking flange upon the transmission of forces between said sleeves.
Claim 3
Dependent Claim
173 words
A removable and replaceable cover for a container such as an aerosol container having a domed roof, a circular collar having an undersurface located above said domed roof and surrounding a dispensing actuator, said cover including: a top wall, a relatively thin flexible outer sleeve depending from said top wall, a relatively thin flexible inner sleeve generally coaxial with said outer sleeve and also depending from said top wall, an inwardly projecting distortable locking flange carried by said inner sleeve and adapted to engage the undersurface of said circular collar of said container when said cover is installed on said container, at least one slit formed in said inner sleeve and extending through said locking flange to allow distortion of said locking flange, and a plurality of ribs connecting said inner and outer sleeves to transmit forces applied to said outer sleeve between said sleeves, said ribs being spaced around the periphery of said inner sleeve so as to cause distortion of said locking flange upon the transmission of forces between said sleeves.
Claim 4
Dependent Claim
173 words
A removable and replaceable cover for a container such as an aerosol container having a domed roof, a circular collar having an undersurface located above said domed roof and surrounding a dispensing actuator, said cover including: a top wall, a relatively thin flexible outer sleeve depending from said top wall, a relatively thin flexible inner sleeve generally coaxial with said outer sleeve and also depending from said top wall, an inwardly projecting distortable locking flange carried by said inner sleeve and adapted to engage the undersurface of said circular collar of said container when said cover is installed on said container, at least one slit formed in said inner sleeve and extending through said locking flange to allow distortion of said locking flange, and a plurality of ribs connecting said inner and outer sleeves to transmit forces applied to said outer sleeve between said sleeves, said ribs being spaced around the periphery of said inner sleeve so as to cause distortion of said locking flange upon the transmission of forces between said sleeves.
Claim 5
Dependent Claim
21 words
The cover of claim 1 in which at least a pair of said ribs are generally diametrically opposed to each other.
Claim 6
Dependent Claim
26 words
The cover of claim 2 in which two pairs of generally diameterically opposed ribs are provided with said pairs being located 90* relative to each other.
