Abstract: The present invention is directed to a system and method for transferring specimen containers between detection instruments. The method may include transporting a specimen container in a locator well to a container transfer station in a first automated detection apparatus; sensing the specimen container at the container transfer station using a first sensor; transferring the specimen container from the container transfer station of the first automated microbial detection apparatus to an automated loading mechanism of a second automated microbial detection apparatus; detecting that the specimen container is positioned over the automated loading mechanism of the second automated microbial detection apparatus using a second sensor; and releasing the specimen container onto the automated loading mechanism of the second automated microbial detection apparatus.

Abstract: The present invention is directed to a system and method for establishing and/or maintaining proper alignment of a transfer mechanism. More specifically, the present invention is directed to an alignment system and method having one or more of: (a) a laser alignment device operable to providing precise locational coordinates for alignment of a robotic transfer mechanism relative to a holding structure; (b) an alignment tool for aligning a laser alignment device relative to robotic transfer mechanism; (c) lead in ramps to properly guide an individual specimen container into a holding well; and/or (d) a belt tensioning device for maintaining proper tension on one or more timing belts.

Abstract: A manually operated trigger sprayer includes a feature that limits the forward pivoting movement of the trigger. By limiting the forward pivoting movement of the trigger, the novel construction of the trigger sprayer prevents the trigger from engaging against the nozzle assembly attached to the sprayer housing of the trigger sprayer and potentially dislodging the nozzle assembly from its attachment to the trigger sprayer housing.

Abstract: The present invention pertains to the construction of a manually operated trigger sprayer in which the sprayer housing has a reduced diameter dimension liquid discharge passage to increase the velocity of liquid flow through the liquid discharge passage, and in which the nozzle assembly has a novel configuration that securely attaches the nozzle assembly to the sprayer housing to prevent the increased velocity of liquid flow through the sprayer housing liquid discharge passage from dislodging the nozzle assembly from the sprayer housing. The novel construction of the sprayer housing and the nozzle assembly includes a resilient crossbar provided on the sprayer housing that crosses over the liquid discharge passage and a pair of resilient flanges on the nozzle assembly that engage over opposite sides of the sprayer assembly crossbar and securely attaching the nozzle assembly to the sprayer housing.

Abstract: A trigger sprayer has a venting apparatus with a unique construction that is formed by the combination of a sprayer housing of the trigger sprayer and a plug seal assembled to the sprayer housing. The plug seal includes a dip tube connector, a valve seat, an annular rim seal, and a portion of the air vent baffle apparatus that are combined as one integral piece.

Abstract: A manually operated trigger sprayer is constructed with a reduced number of parts and in a novel manner in which all of the component parts of the sprayer are constructed of a plastic material. The construction of the trigger sprayer replaces the conventional metal coil spring in the pump chamber with a pair of plastic bowed springs that are integral with the piston rod and are positioned outside the pump chamber. Constructing all of the sprayer parts of a plastic material enables a cost efficient recycling of the parts, which does not require disassembling the parts to remove a metal spring.

Abstract: A manually operated trigger sprayer is constructed with a reduced number of parts and in a novel manner in which all of the component parts of the sprayer are constructed of a plastic material. The construction of the trigger sprayer replaces the conventional metal coil spring in the pump chamber with a pair of plastic springs having inverted U-shaped configurations that are integral with the piston rod and are positioned outside the pump chamber. Constructing all of the sprayer parts of a plastic material enables a cost efficient recycling of the parts, which does not require disassembling the parts to remove a metal spring.

Abstract: A closure apparatus for a bottle neck and cap increases the torque necessary to remove the cap from the bottle neck. Projections are provided on one of the bottle neck exterior and cap interior, and indentations are provided on the other of the bottle neck exterior and cap interior. When the cap is secured on the bottle neck, the projections engage in the indentations. The engagement of the projections in the indentations requires an increased torque to remove the cap from the bottle neck.

Abstract: A venting system of a manually operated trigger sprayer vents the interior of a liquid container connected to the trigger sprayer. The trigger sprayer is provided with a vent chamber that surrounds the pump chamber, and a vent piston that surrounds the pump piston. The vent piston is received in the vent chamber for reciprocating movements with the pump piston in the pump chamber. The reciprocating movement of the vent piston alternatively opens the vent chamber to the exterior environment of the trigger sprayer and thereby vents the interior of the liquid container connected to the trigger sprayer, and closes the vent chamber thereby sealing the interior of the liquid container from the exterior environment.
