Abstract

A spouted container comprises a container and a vented spout that fluidly communicates with the container. The vented spout defines a fluid passageway extending therethrough and includes a conduit housing and a cover that cooperatively form a vented chamber. The vented chamber fluidly communicates with the passageway through a pair of spaced apart vent openings presented by the conduit housing. The vented chamber also fluidly communicates with ambient through a vent opening presented by the cover. The vented spout further includes a locking valve assembly that restricts inadvertent opening of the spouted container. The assembly includes a shiftable valve that normally occludes the passageway and a trigger operably coupled to the valve for opening and closing the valve. The trigger includes a catch that holds the trigger in a locked condition when the valve is closed.

Claims14

Dependent claims

A normally-closed pour spout operable to pour fluid from a container to a receptacle, said container operable to store fluid and presenting an opening, said normally-closed pour spout comprising:

a fluid conduit operable to be removably attached to the container,
said fluid conduit including a conduit wall that forms a passageway configured to pass fluid therethrough;
and
a locking valve including a trigger shiftably attached relative to the wall and a shiftable valve element positioned relative to the wall for movement into and out of a normally closed valve position, in which the passageway is occluded,
said trigger including a trigger lever and a shiftable catch,
said trigger lever operably coupled to the valve element so that movement of the trigger lever in a valve-opening direction causes the valve element to shift out of the closed valve position,
said catch shiftable into and out of a locking condition when the valve element is in the closed valve position, wherein the catch engages the trigger lever and thereby restricts the trigger lever from moving in the valve-opening direction,
said catch having an unlocked condition where the catch is disengaged to permit movement of the trigger lever in the valve-opening direction, with movement of the catch from the locking condition to the unlocked condition requiring the catch to shift, at least in part, along a first direction and then along a nonparallel second direction before the trigger lever is permitted to move in the valve-opening direction and thereby permit shifting of the valve element out of the closed valve position,
said trigger including a first spring element that urges the catch in a direction opposite the first direction,
said trigger including a second spring element that urges the catch in a direction opposite the second direction, with the springs cooperatively biasing the catch into the locking condition.

A normally-closed pour spout operable to pour fluid from a container to a receptacle, said container operable to store fluid and presenting an opening, said normally-closed pour spout comprising:

a fluid conduit operable to be removably attached to the container,
said fluid conduit including a conduit wall that forms a passageway configured to pass fluid therethrough;
and
a locking valve including a trigger shiftably attached relative to the wall and a shiftable valve element positioned relative to the wall for movement into and out of a normally closed valve position, in which the passageway is occluded,
said trigger including a trigger lever and a shiftable catch,
said trigger lever operably coupled to the valve element so that movement of the trigger lever in a valve-opening direction causes the valve element to shift out of the closed valve position,
said catch shiftable into and out of a locking condition when the valve element is in the closed valve position, wherein the catch engages the trigger lever and thereby restricts the trigger lever from moving in the valve-opening direction,
said catch being shiftable out of the locking condition by shifting, at least in part, along a first direction and then shifting in a nonparallel second direction to permit movement of the trigger lever in the valve-opening direction and thereby shifting of the valve element out of the closed valve position,
said trigger lever being shiftably attached relative to the conduit wall,
said catch being shiftably mounted to the trigger lever so that the catch and trigger lever move together when the trigger moves in the valve-opening direction,
said catch interconnecting the conduit wall and the trigger lever in the locking condition to restrict relative movement therebetween,
said trigger including a first spring element that urges the catch in a direction opposite the first direction,
said trigger including a second spring element that urges the catch in a direction opposite the second direction, with the springs cooperatively biasing the catch into the locking condition.
