DETAILED DESCRIPTION OF THE INVENTION

[0033] Referring to FIG. 1, a prior art embodiment of a container for use with a nested sprayer handle is shown. Generally, a sprayer handle (not shown) may be secured between lugs 30, 50 within opening 25. However, flat panel 33 is prone to deformation, particularly downward flexure, causing undesirable dimensional changes to opening 25. Such dimensional changes to opening 25 typically cause the sprayer handle to loosen when in a stored position, and thereby result in dislodgment of the sprayer handle in shipment, retail locations, or during use.

[0034] Referring to FIGS. 2-8, a bulk container 100 according to the present invention is shown. Bulk container 100 includes side walls 110 and 112, front wall 114, rear wall 116, a bottom wall 118, and a top wall 124. The walls of bulk container 100 collectively define an interior volume of the container. In the embodiment shown, front and rear walls 114, 166 are generally planar, while side walls 110, 120 are provided with a moderate curvature. In other embodiments, each of walls 110, 112, 114, and 116 may include any combination of generally planar and generally curved walls.

[0035] In the embodiment shown, container 100 is generally symmetrical about the center plane, that is, the plane defined by the intersection of center lines 150, 152, with the exception of some features of top wall 124. In other embodiments, additional features of top surface 124 and/or other portions of container 100 may be asymmetric about the center plane to accommodate, for example, different configurations of a sprayer handle 200. It will be additionally appreciated by those of skill in the art that references to right and left in the description below may be mirrored without changing the inventive aspects of the container 100.

[0036] As shown, bulk container 100 includes a top wall 124 and a carrying handle 126. Carrying handle 126 includes a horizontal handle portion 127, front riser 128, and rear riser 130. In a typical embodiment, horizontal handle portion 127, front riser 128, and rear riser 130 of carrying handle 126 are hollow and in fluid communication with the interior volume of bulk container 100. Top wall 124 and carrying handle 126 together define a carrying handle opening 132. A threaded neck portion 120 defining an annular product opening 122 provides access to the interior volume of bulk container 100. As shown, threaded neck portion 120 is provided on front riser 128.

[0037] In various typical embodiments, container 100 is a plastic. In one preferred embodiment, container 100 is formed from extruded high density polyethylene (HDPE) having an average wall thickness of about 1.0 millimeter. In other embodiments, container 100 may be formed from any extrudable blow-molded material, such as Polypropylene (PP), nylon, Polyvinyl Chloride (PVC), and Polyethylene Terephthalate (PET), and having an average wall thickness of 0.6 to 2.0 millimeters.

[0038] In various embodiments, container 100 may have an effective internal volume of between 0.5 gallons to 5 gallons, preferably between about 1 gallon and 2.5 gallons. Particularly preferred embodiments of container 100 include an effective internal volume of about 1 gallon, 2 gallons, or 2.5 gallons. By effective internal volume it is meant the nominal storage capacity of a liquid within container 100 to a fill line that is below the level of product opening 122.

[0039] Referring now to FIGS. 3-7, the top wall 124 of container 100 is divided in to discrete areas to reduce or eliminated downward paneling or saddling of top wall 124 in response to a reduced pressure in the interior volume of a container 100. Such reduced pressure may result from evaporative product loss from within container 100, changes in temperature of the contents or environment of container 100, or withdrawal of the contents of container 100 via a sprayer handle 200 (shown in FIG. 8).

[0040] Top wall 124 may be provided with a tubular recess 146. Tubular recess 146 may be shaped to receive portions of sprayer handle 200. Tubular recess 148 includes an upwardly-protruding snap lug 148 configured to engage a corresponding recess in head 208 of sprayer handle 200. As best shown in FIGS. 5 and 7, carrying handle 126 is provided with a downwardly protruding snap lug 149 vertically opposed to snap lug 148 and configured to engage a corresponding recess in head 208 of sprayer handle 200. In a preferred embodiment, snap lugs 148, 149 are located on the center plane of the container 100 and are vertically aligned along a line parallel to vertical axis 152.

[0041] In the embodiment shown, the left side 176 of top wall 124 extends from the center plane defined by center lines 150, 152 in the direction of side wall 112. Similarly, the right side 178 of top wall 124 extends from the center plane defined by center lines 150, 152 in the direction of side 110.

[0042] Left side 176 of top wall 124 includes a generally planar surface, here shown as the flat surface or plane defined panels by 166, 174. As shown, the generally planar surface of left side 176 is slightly lower towards the rear 130 of container 100. In a typical embodiment, the generally planar surface of left side 176 is sloped downward at an angle of about 4 degrees with respect to the horizontal plane defined by center lines 150, 151.

[0043] At transition zones 168, 172, top wall 124 is provided with a raised arch 170 panel extending upwards from the plane of top wall 124 defined by panels 166, 174. In the embodiment shown, raised arch panel 170 smoothly transitions from panels 166, 174. In other embodiments, transition zone 168 may be proximate to tubular recess 146, such that the there is little or no discrete panel 166 between tubular recess 146 and raised arch panel 170. In typical embodiments, the peak height of arch 170 above the plane defined by panels 166, 174 is between about 0.2 inch to 0.5 inch. In a preferred embodiment, the peak height of arch 170 above the plane defined by panels 166, 174 is between about 0.3 inch to 0.4 inch, and in a particularly preferred embodiment is 0.345 inches.

[0044] Right side 178 of top wall 124 also includes a generally planar surface, here shown as the flat surface or plane defined by panels 140, 141. As shown, the generally planar surface of right side 178 is slightly lower towards the rear 130 of container 100. In a typical embodiment, the generally planar surface of right side 178 is sloped downward at an angle of about 4 degrees with respect to the horizontal plane defined by center lines 150, 151.

[0045] A transverse wedge 180 extends from the center plane defined by center lines 150, 152 in the direction of side 110. In various embodiments, the width of transverse wedge 180 in the direction parallel to center line 150 is between about 0.25 inch to about 2.5 inches. In a preferred embodiment, the width of transverse wedge 180 in the direction parallel to center line 150 is between about 0.7 inch to about 0.8 inch. As shown, the height of transverse wedge 180 above top wall 140/141 proximate to the center plane is approximately 0.22 inch.

[0046] In various embodiments, the maximum height of arch 170 is between about 0.1 inches to 0.4 inches higher than maximum height of transverse wedge 180 above top wall 124. In a preferred embodiment, the maximum height of arch 170 is between about 0.2 inches to 0.3 inches higher than maximum height of transverse wedge 180 above top wall 124. Generally, the maximum height of transverse wedge 180 is selected to allow nesting of grip portion 206 of sprayer handle 200 within handle opening 132 and above transverse wedge 180, as shown in FIG. 8.

[0047] In a preferred embodiment, transverse wedge 180 is positioned between panels 140, 141 such that each of panel 140, 141 have approximately the same width in the direction parallel to center line 150. In other embodiments, panel 140 may have a width greater or lesser than the width of panel 141 in the direction parallel to center line 150. In other embodiments, transverse wedge may be proximate to tubular recess 146, such that there is little or no discrete panel 140 between tubular recess 146 and raised transverse wedge 180. Alternatively, transverse wedge 180 may be positioned to the rear of container 100 and proximate to rear riser 130, such that there is little or no discrete panel 140 between rear riser 130 and transverse wedge 180.

[0048] As best shown in cross-sectional view of FIG. 7, the generally planar surface of the right side 178 defined by panels 140, 141 and the generally planar surface of the left side 176 defined by panels 166, 174 intersect at the center plane. In a preferred embodiment, panels 140 and 166 may intersect at a slight angle as shown. In another embodiment, panels 140 and 166, and the generally planar surfaces of sides 176, 178 may be co-planar.

[0049] In a preferred embodiment, sprayer handle 200 is removably secured within opening 132 by snap-fit, without provision of an adhesive, wire tie, tape, or other types of additional securement devices. In the exemplary embodiment show, sprayer handle 200 includes a bottom end 202 and a hand grip 206. Hand grip 206 may be hollow, to thereby allow storage of a connecting tube (not shown). The connecting tube may be used to removably couple sprayer handle 200 to threaded neck portion 120, to thereby facilitate spraying of the contents of container 100 via sprayer handle 200.

[0050] As best shown in FIG. 8, to snap-fit sprayer handle 200 within opening 132 of container 100, one or more lugs of container 100 are received by complementary recesses provided in sprayer handle 200. In the exemplary embodiment shown, a cylindrical lug 162 is received by lower complementary recess 204 positioned at the bottom end 202 of sprayer handle 200. Top end 208 of sprayer handle 200 further includes two upper complementary recesses (not shown) positioned on either side of top end 208 which are configured to receive lower snap lug 148 and upper snap lug 149. Accordingly, when upper recesses are engaged with snap lugs 148, 149 and lower recess is engaged with cylindrical lug 162, sprayer handle 200 will be securely positioned within opening 132 of container 100. When sprayer handle 200 is nested in opening 132 of container 100, sprayer head 208 is thereby mechanically held within opening 132 by engagement of snap lugs 148, 149 with sprayer head 208 of sprayer handle 200.

[0051] In alternate embodiments, container handle opening may be provided with recesses instead of lugs, and nested sprayer handle 200 may be provided with complementary lugs configure to snap fit into such recesses of the container handle opening. As will be appreciated by those of skill in the art, the container handle opening 132 and sprayer handle 200 may be provided with other types of complementary mechanical engagement portions to thereby allow a user to mechanically secure the sprayer handle 200 within container handle opening 132.

[0052] The three-dimensional structure of arch 170 and transverse wedge 180 of top wall 124 is configured to reduce or eliminate the deflection of top wall 124 inward and toward the internal volume of container 100, thereby minimizing flexure of handle opening 132. By reducing flexure of handle opening 132, the snap-fit tolerances provided to sprayer handle 200 are improved, thereby improving the retention of sprayer handle 200 by snap lugs 149, 148 and cylindrical lug 162, without the need for an additional securements such as a glue, adhesive, zip or wire tie, etc.
