Abstract

Abstract A resealable container is provided for storing and dispensing liquids. The container is formed in a one-piece molded construction and includes a cap covering an outlet defined by an externally threaded neck, with a frangible section coupling the cap to the neck. An outer ring is threadedly interfitted over the cap in engagement with the neck, with the outer ring having a plurality of inwardly extending slightly flexible fingers which fit around the cap to captivate the cap. The cap is forced downwardly during downward rotation of the outer ring thereby severing the cap from the neck at the frangible section.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 145 words
A resealable container for storing and dispensing liquids, said container including a neck defining a dispensing outlet and a cap covering said outlet, a frangible section coupling said cap to said neck, the improvement comprising: said cap having an outwardly extending retaining abutment and an outwardly extending bearing surface spaced downwardly from said retaining abutment; said neck carrying external threads; and an outer ring having internal threads for threaded engagement with the external threads of said neck, said outer ring having a plurality of inwardly extending slightly flexible fingers for fitting around the cap intermediate said retaining abutment and bearing surface, whereby downward rotation of said outer ring will force said outer ring against said bearing surface thereby severing the cap from the neck at the frangible section and upper rotation of said outer ring will place said fingers into engagement with said retaining abutment.
Claim 2
Dependent Claim 145 words
A resealable container for storing and dispensing liquids, said container including a neck defining a dispensing outlet and a cap covering said outlet, a frangible section coupling said cap to said neck, the improvement comprising: said cap having an outwardly extending retaining abutment and an outwardly extending bearing surface spaced downwardly from said retaining abutment; said neck carrying external threads; and an outer ring having internal threads for threaded engagement with the external threads of said neck, said outer ring having a plurality of inwardly extending slightly flexible fingers for fitting around the cap intermediate said retaining abutment and bearing surface, whereby downward rotation of said outer ring will force said outer ring against said bearing surface thereby severing the cap from the neck at the frangible section and upper rotation of said outer ring will place said fingers into engagement with said retaining abutment.
Claim 3
Dependent Claim 68 words
A resealable container as described in claim 1, said flexible fingers having an internal diameter that is smaller than the external diameter of said retaining abutment, but are sufficiently flexible to flex over the retaining abutment when the outer ring is initially threaded downwardly with respect to said neck, whereby the fingers will snap into the surface of the cap intermediate the retaining abutment and the bearing surface.
Claim 4
Dependent Claim 21 words
A resealable container as described in claim 1, said neck, cap and frangible section being formed in a one-piece molded construction.
Claim 5
Dependent Claim 56 words
A reseable container as described in claim 1, said cap including a top portion and downwardly extending sidewall portion, said sidewall portion including said retaining abutment adjacent the top portion, a main surface extending downwardly from said retaining abutment, said bearing surface located below said main surface, and said frangible section located below said bearing surface.
Claim 6
Dependent Claim 257 words
A resealable container for storing and dispending liquids, said container including a neck defining a dispensing outlet and a cap covering said outlet, a frangible section coupling said cap to said neck, the improvement comprising: said cap including a top portion and a downwardly extending sidewall portion, said sidewall portion having an outwardly extending retaining abutment adjacent between the top portion, the main surface extending downwardly from said retaining abutment, and an outwardly extending bearing surface located below said main surface; said frangible section being located below said outwardly extending bearing surface; said neck, cap and frangible section being formed in a one-piece molded construction with said neck carrying external threads; an outer ring having internal threads for threaded engagement with the external threads of said neck; said outer ring having a plurality of inwardly extending slightly flexible fingers for fitting around the cap on said main surface thereof, said flexible fingers having an internal diameter that is smaller than the external diameter of said retaining abutment, but are sufficiently flexible to flex over the retaining abutment when the outer ring is initially threaded downwardly with respect to said neck, whereby when the outer ring is intially threaded downwardly with respect to said neck the fingers will snap into said main surface and whereby downward rotation of said outer ring will force said outer ring against said bearing surface thereby severing the cap from the neck at the frangible section and upward rotation of said outer ring will place said fingers into engagement with said retaining abutment.
Claim 7
Dependent Claim 257 words
A resealable container for storing and dispending liquids, said container including a neck defining a dispensing outlet and a cap covering said outlet, a frangible section coupling said cap to said neck, the improvement comprising: said cap including a top portion and a downwardly extending sidewall portion, said sidewall portion having an outwardly extending retaining abutment adjacent between the top portion, the main surface extending downwardly from said retaining abutment, and an outwardly extending bearing surface located below said main surface; said frangible section being located below said outwardly extending bearing surface; said neck, cap and frangible section being formed in a one-piece molded construction with said neck carrying external threads; an outer ring having internal threads for threaded engagement with the external threads of said neck; said outer ring having a plurality of inwardly extending slightly flexible fingers for fitting around the cap on said main surface thereof, said flexible fingers having an internal diameter that is smaller than the external diameter of said retaining abutment, but are sufficiently flexible to flex over the retaining abutment when the outer ring is initially threaded downwardly with respect to said neck, whereby when the outer ring is intially threaded downwardly with respect to said neck the fingers will snap into said main surface and whereby downward rotation of said outer ring will force said outer ring against said bearing surface thereby severing the cap from the neck at the frangible section and upward rotation of said outer ring will place said fingers into engagement with said retaining abutment.
