Abstract

A tub-type container having a one-hand operable latch includes a tub portion with an upper edge, a front wall, a rear wall and first and second side walls, the walls integrally joined to each other. A skirt depends from a peripheral edge of at least the front wall, and a forwardly projecting flange extends from the skirt along at least a portion of the front wall. The container also has a lid including a peripheral edge and front, rear, and first and second side portions corresponding to the walls of the container, the lid provided with a skirt depending from at least the front portion of the lid. The container is provided with a handle formation integrally formed into the skirt on the front side and projecting vertically above the peripheral edge, the handle formation being pivotable from a generally vertical closed position to a rearwardly projecting open position. A latch formation disposed at a lower edge of the skirt on the front side includes a groove formation for matingly engaging the flange of the tub portion, whereby rearward pressure on the handle disengages the groove formation from the flange to release the latch.

Dependent claims

A tub-type container having a one-hand operable latch, comprising:

a tub portion with an upper edge, a front wall, a rear wall and first and second side walls, said walls integrally joined to each other;
a tub skirt depending from said upper edge of at least said front wall;
a forwardly projecting flange extending from said tub skirt along at least a portion of said front wall;
a lid including a top surface, a peripheral edge and front, rear, and first and second side portions corresponding to said walls of said tub portion and defining a lid skirt which depends from said peripheral edge;
hinge means disposed along a corresponding one of said portions of said lid and said walls of said tub portion for securing a lower edge of said lid to said tub portion;
a handle of a generally inverted U-shaped cross section integrally formed with said lid skirt and generally coextensive with said lid skirt on a front side of said handle and generally coextensive with the top surface of the lid on a rear side of said handle and projecting vertically above said peripheral edge to form a grasping surface, said handle being pivotable from a generally vertical position to a rearwardly projecting position;
latch means disposed on said lid skirt on said front portion adjacent to the front side of said handle and releasably latching said lid to said tub portion, and said latch means including a groove formation matingly engaging said flange of said tub skirt in a locked position of said latch means which corresponds to the vertical position of said handle;
said handle being arranged above said latch means so that an upwardly directed grasping force applied to said grasping surface will lift said container and maintain engagement of said latch means with said flange of said tub skirt;
wherein rearward pressure on said handle pivots said handle rearwardly and pivots said groove formation forwardly to disengage said groove formation from said flange to unlock said latch means.

A tub-type container having a one-hand operable latch comprising:

a tub portion with an upper edge, a front wall, a rear wall and first and second side walls, said walls integrally joined to each other;
a tub skirt depending from said upper edge of at least said front wall;
a forwardly projecting flange extending from said tub skirt along at least a portion of said front wall;
a lid including a top surface, a peripheral edge and front, rear, and first and second side portions corresponding to said walls of said tub portion and defining a lid skirt which depends from said peripheral edge;
hinge means disposed at said rear portion of said lid and said rear wall of said tub portion for securing a lower edge of said lid to said tub portion;
a handle of a generally inverted U-shaped cross section integrally formed into said lid skirt on a front side of said handle and integrally formed into said top surface of the lid on a rear side of said handle projecting vertically above said peripheral edge to form a grasping surface, said handle being pivotable from a generally vertical position to a rearwardly projecting position;
latch means disposed at a lower portion of said lid skirt directly below said handle on said front portion of said lid releasably latching said lid to said tub portion and including a groove formation matingly engaging said flange of said tub skirt in a locked position of said latch means which corresponds to the vertical position of said handle;
and
said handle is coextensive with said latch means on said front portion of said lid so that an upwardly directed grasping force applied to said handle will lift said container and maintain engagement of said latch means with said flange of said tub skirt;
wherein rearward pressure on said handle pivots said handle rearwardly and pivots said groove formation forwardly to disengage said groove formation from said flange to unlock said latch means.
