Abstract
A container comprising a container body having a neck, the neck having inner and outer surfaces and a rim extending between tops of the inner and outer surfaces, and the rim defining a circular opening. The closure has a centre panel, the closure defining an annular channel. An annular gasket is disposed in the annular channel and the annular channel receives said rim of said neck such that the annular gasket forms a seal between said rim and said closure. When the container body is closed by the closure, the difference between an inside radius of the annular channel at a channel depth of 0.2 mm and an inside radius of said rim is less than substantially 0.9 mm.

A container comprising:
- a container body having a neck, the neck having inner and outer surfaces and a rim extending between tops of the inner and outer surfaces, and the rim defining a circular opening;
- and
- a closure having a centre panel, the closure defining an annular channel, and an annular gasket disposed in the annular channel, the annular channel receiving said rim of said neck such that the annular gasket forms a seal between said rim and said closure,
- wherein, when the container body is closed by the closure, the difference between an inside radius of the annular channel at a channel depth of 0.2 mm and an inside radius of said rim is less than 0.7±0.225 mm;
- and
- wherein when the container body is closed by the closure, a portion of the annular gasket is exposed to a volume enclosed by the container body, and a radial dimension of the exposed portion is less than 1.0 ±0.225 mm.

A container comprising:
- a container body having a neck, the neck having inner and outer surfaces and a rim extending between tops of the inner and outer surfaces, and the rim defining a circular opening, and a thread on the outer surface of the neck;
- and
- a closure having a centre panel and a depending sidewall, the closure defining an annular channel between the centre panel and the sidewall, and an annular gasket disposed partially in the annular channel and partially on the inside of the sidewall for engaging with said thread, the annular channel receiving said rim of said neck such that the annular gasket forms a seal between said rim and said closure,
- wherein, when the container body is closed by the closure, an inside radius of the annular gasket is greater than an inside radius of said rim;
- and
- wherein the annular gasket extends over and engages with a thread on the outer surface of the neck thereby deforming to match the shape of the thread.
