Claims
- 1. A container defining a cavity with an opening to a neck, and having a cap releasably secured on the neck covering the opening, a liner disposed within the cavity and including an end flange by which the liner is supported from the upper end of the neck, an inner end, a liquid containing cavity at the inner end, an annular shoulder located internally and spaced from the inner end, the annular shoulder facing towards the end flange, and a sealing element comprising a head adapted to abut the annular shoulder and to form a liquid-tight seal therewith and a stem extending towards the end flange, an outer end of the stem being arranged for engagement with an underside of the cap such that when the cap is secured on the neck the head of the sealing element is held in sealing engagement with the annular shoulder, wherein said stem of said sealing element is smaller in outer diameter than said head of said sealing element, and said stem extends away from said head for engagement with an underside of the cap.
- 2. A container device for the storage and transportation of hazardous liquids, comprising:
- a container part having an exterior surface, and an interior surface defining a cavity having an opening through said exterior surface;
- a cap releasably securable to said exterior surface in covering relation to said opening of said cavity;
- a liquid containing vial removably disposed within said cavity, said vial having an inner surface, an outer surface, an upper portion engaged with said interior surface of said container part, an annular shoulder having an inner surface facing towards said upper portion and an outer surface spaced inwardly from and being free of said interior surface of said container part, and a lower portion depending from said annular shoulder; and
- a sealing element removably disposed within said vial, said sealing element having a head for contacting against and forming a liquid-tight seal with said annular shoulder of said vial, and a stem extending away from said head, said sealing element including removal means for enabling removal of said sealing element from said vial and thereby providing access to liquid contained within said vial without removal of said vial from said cavity.
- 3. A container device as claimed in claim 2, wherein
- said removal means comprises a tool-engagement recess formed in an end of said sealing element opposite said head.
- 4. A container device as claimed in claim 3, wherein
- said tool-engagement recess is conical.
- 5. A container device as claimed in claim 2, wherein
- said removal means comprises an end portion of said sealing element, said end portion being disposed at least partially above said vial and outside of said cavity.
- 6. A container device as claimed in claim 5, wherein
- said end portion of said sealing element is one piece with said stem of said sealing element.
- 7. A container device as claimed in claim 2, wherein
- said lower portion of said vial is spaced inwardly from and free of said interior surface of said container part.
- 8. A container device for the storage and transportation of hazardous liquids, comprising:
- a container part having an exterior surface, and an interior surface defining a cavity having an opening through said exterior surface;
- a cap releasably securable to said exterior surface in covering relation to said opening of said cavity;
- a liquid containing vial removably disposed within said cavity, said vial having an inner surface, an outer surface, an upper portion engaged with said interior surface of said container part, an annular shoulder having an inner surface facing towards said upper portion and an outer surface spaced inwardly from and being free of said interior surface of said container part, and a lower portion depending from said annular shoulder; and
- a sealing element removably disposed within said vial, said sealing element having a head for contacting against and forming a liquid-tight seal with said annular shoulder of said vial, a stem extending away from said head, and an end portion which is one piece with said stem and is disposed at least partially above said vial and outside of said cavity so as to constitute a sealing element removal portion.
- 9. A container device as claimed in claim 8, wherein
- said end portion of said sealing element is secured to said cap such that, upon removal of said cap from said container part, said sealing element is removed from said vial.
- 10. A container device as claimed in claim 8, wherein
- said lower portion of said vial is spaced inwardly from and free of said interior surface of said container part.
- 11. A container device as claimed in claim 8, wherein
- an outer end of said upper portion of said vial extends above said container part, and said end portion of said sealing element is removably adjoined with said outer end of said end portion of said vial.
