Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
124 words
In combination, a thermoplastic container having a body portion, a first neck portion and a second neck portion integrally formed with said first neck portion and having an end closure on it which normally permanently seals said container, one of said first and second neck portions having fine threads on it and the other one thereof having coarse threads on it, an end cap threadedly secured to said container having a neck cavity with a finely threaded portion and a coarsely threaded portion in it for receiving said first and second neck portions, the construction being such that said second neck portion and said end closure on it are severed to provide an opening into said container when said end cap is screwed down.
Claim 2
Dependent Claim
124 words
In combination, a thermoplastic container having a body portion, a first neck portion and a second neck portion integrally formed with said first neck portion and having an end closure on it which normally permanently seals said container, one of said first and second neck portions having fine threads on it and the other one thereof having coarse threads on it, an end cap threadedly secured to said container having a neck cavity with a finely threaded portion and a coarsely threaded portion in it for receiving said first and second neck portions, the construction being such that said second neck portion and said end closure on it are severed to provide an opening into said container when said end cap is screwed down.
Claim 3
Dependent Claim
50 words
The combination of claim 1, wherein said first and said second neck portions are coupled together with a reduced diameter neck portion integrally formed therewith, said reduced diameter neck portion being severed when said end cap is screwed down to sever said second neck portion from said first neck portion.
Claim 4
Dependent Claim
60 words
The combination of claim 1, wherein said second neck portion is of a smaller diameter than said first neck portion and the portions of said neck cavity in said end cap receiving them are correspondingly sized, whereby said end cap can be threadedly secured to said container for storage and/or shipment without severing said second neck portion from said container.
Claim 5
Dependent Claim
50 words
The combination of claim 1, wherein said second neck portion upon being severed is threadedly secured and retained within said end cap, whereby said end cap can be threadedly removed from said container to permit the contents thereof to be dispensed and again threadedly affixed thereto to reseal said container.
Claim 6
Dependent Claim
75 words
The combination of claim 1, further including an annular cutting blade carried by said end cap and positioned therein to sever said second neck portion and said end closure on it when said end cap is screwed down to provide an opening in said container through which the contents thereof can be dispensed, said severed second neck portion and end closure being threadedly secured and retained within said end cap when the latter is removed.
Claim 7
Dependent Claim
115 words
The combination of claim 1, wherein said end closure comprises an inverted cone-shaped tip, said end cap having a threaded bore extending therethrough axially aligned with said neck cavity therein for receiving said end closure, an annular cutting blade carried by said end cap and positioned therein to sever said second neck portion and said end closure when said end cap is screwed down to provide an opening in said container through which the contents thereof can be dispensed, said second neck portion being threadedly secured and retained within said threaded bore, thereby sealing said container until said end cap is threadedly removed and being removed with said end cap when the latter is removed.
Claim 8
Dependent Claim
49 words
The combination of claim 6, further including an annular recessed groove outwardly of said annular cutting blade forming a sealing cavity, the top wall of said first neck portion being forcibly urged into said sealing cavity to seal said container against leakage when said end cap is screwed down.
Claim 9
Dependent Claim
63 words
The combination of claim 6, wherein said end closure is threadedly secured and retained within said end cap thereby permitting it to be removed therewith to permit the contents of said container to be placed therein or mixed with another product, the end cap to be replaced and the contents then dispensed through said cone-shaped tip by severing a portion of the latter.
