Abstract
A non-metallic safety filling container is formed as a hollow wall having a continuously closed inner surface, terminating at openings for venting, pouring and filling. A trigger mechanism mounted to the container simultaneously vents the container and slides a ported cylinder into position to complete a pouring path from the interior of the container through the pour spout.
Claims10
A plastic safety container having a wall with a continuously closed inner surface, comprising:
- separate openings formed in said wall for filling, venting, and pouring from said container,
- the first of said openings, used for filling said container, located on the top of said container and comprising a cylindrical upstanding tube extending into said container;
- the second of said openings, used for emptying said container, being located on the side of said container and comprising a substantially horizontal tube extending from an open end into said container;
- and
- the third of said openings, used for venting said container, forming a communicating passageway between the exterior and interior wall surfaces of said container;
- means for sealing said second of said openings,
- said sealing means slidably engaged within said second of said openings to selectively seal and unseal said second of said openings;
- means for controlling the sliding of said sealing means,
- said control means mounted to the exterior of said container;
- and
- a single shaft having two ends,
- the first of said ends attached to said seal means,
- the second of said ends attached to said control means;
- and
- means for venting said third of said openings,
- said venting means positioned within the third of said openings,
- said sealing means, said shaft said control means and said venting means being aligned in fixed spatial relationship whereby operating said control means draws said sealing means inwardly from said second of said openings to complete a pour path from the interior of said container while simultaneously operating said venting means to complete a venting passage from the interior of said container to the exterior.
In a safety container formed with an all plastic wall having a continuously closed inner surface having at least three openings formed therein, the improvement comprising:
- a cylindrical upstanding filling tube extending into said container at the first of said openings;
- a substantially horizontal pouring tube extending from an open end into said container at the second of said openings;
- a hollow cylindrical seal coaxial with and slidably engaged partially within said horizontal tube,
- said seal forming a communicating passageway whereby when said seal is drawn axially into said horizontal tube, a pour path is completed through said passageway and said pouring tube from the interior of said container to the atmosphere,
- said seal being spring-biased to rest normally in a position to interrupt said pour path;
- a shaft having two ends,
- the first of said ends integrally attached to said seal;
- a trigger,
- said trigger mounted exteriorly on said upstanding filling tube,
- the second of said shaft ends being attached to said trigger;
- and
- a selectively defeatable vent valve within the third of said openings,
- said vent valve, said trigger, said shaft, and said seal being aligned whereby drawing on said trigger to axially move said seal to complete said pour path substantially simultaneously defeats said vent valve to complete a venting path therethrough.
