- the exemplary tub has a base 50 ( FIG. 10 ) and a sidewall 52 extending upward from the base to a rim 54 .
- the exemplary tub is of slightly rounded rectangular planform so that, for ease of reference, the four sides are a front 56 ( FIG. 10 ), a back 58 ( FIG. 9 ), a left side/end 60 ( FIG. 10 ), and a right side/end 62 (from the point of view of the container rather than someone facing the container).
- the sidewall branches with an inner wall as a continuation of a main portion of the sidewall and an outer wall 64 extending upward from a junction therewith.
- the outer wall 64 ( FIG. 9 ) extends to a rim 66 and defines a channel 68 between the inner wall and outer wall.
- the outer wall and/or inner wall may bear features for cooperating with the closure 24 .
- these features include a wall 80 extending outward from the outer sidewall 64 to define an open-bottom slot or pocket 82 along the rear/back of the body 22 for receiving an insertion portion of the living hinge member 26 .
- These cooperating features also include detent features 86 ( FIG. 9 ) for cooperating with complementary features of the lid portion 28 .
- the sides 56 , 58 , 60 , 62 of the sidewall 52 meet at generally vertical junctions/corners of the sidewall 52 .
- the exemplary sidewall 52 has a pair of finger reliefs 72 and 74 ( FIG. 10 ) extending along the front corners. These allow gripping by the user (e.g., between thumb and forefinger).
- FIGS. 4-6 show the cover 28 in an as-molded condition.
- FIGS. 7 and 8 show the cover with the hinge insertion portion bent downward.
- the cover 28 extends upward from a lower rim 200 ( FIG. 5 ).
- the cover includes a wall portion 202 extending upward from the rim 200 to a shoulder 204 .
- a top web 206 extends across from the shoulder to enclose the cover.
- the hinge member 26 extends from the shoulder along a rear end of the lid.
- the hinge includes a reduced thickness flexible portion 220 between the shoulder 204 and an insertion portion 222 for receipt in the pocket 82 .
- the insertion portion 222 comprises a frame 230 ( FIG.
- a pawl or barb portion 250 extends from a root at the lower portion 236 to a free end 252 .
- the insertion portion 222 sticks generally straight out parallel to but offset from the web 206 upper surface.
- the pawl 250 extends back toward the flexible portion 220 .
- the pawl 250 has a proximal portion 260 ( FIG. 5 ) joining the frame and extending partially downward and inward therefrom in the as-molded condition and a distal portion 262 extending to the end 252 .
- the insertion portion 222 may be bent 90° (to the FIGS. 7 and 8 condition) about an approximate transverse axis of the portion 220 for insertion into the pocket. This transverse axis effectively forms a hinge axis when the cover is installed.
- FIG. 3A shows the hinge insertion portion 222 installed.
- FIGS. 3, 3A, and 3B reflect artifacts of computer modelling in that some features are shown overlapping due to the software's inability to model the deformations they experience.
- the free end 252 of the pawl forms an upper edge in this orientation captured beneath the underside of an outward projection 270 at the upper edge of a slightly vertically recessed portion of the outer sidewall 64 .
- An upper surface of the projection 270 abuts the edge (lower edge in installed condition) of the frame upper portion 240 . Accordingly, it can be seen that when the hinge insertion portion 222 is inserted via downward movement, the lower portion 236 initially passes between a rear end 276 of the projection 270 and a forward face of the wall 80 . Further downward movement brings the rear end 276 into contact with the adjacent face of the pawl along the proximal portion 260 .
- FIG. 3 shows an approximate hinge axis 500 .
- the hinging may be about multiple parallel instantaneous axes of rotation about the location shown depending upon the state of opening/closing.
- the hinge may be pre-bent to ease assembly.
- the hinge is bent to take an at least temporary set of 90° (the FIGS. 7 and 8 condition) so that a horizontally-oriented lid may be shifted straight downward to install, simultaneously inserting the hinge member and latching the latch. Depending on the product involved, this may be pre-filling or post-filling of the contents.
- Bending may be greater than 90° to provide the 90° set after partial relaxation when the bending moment is removed. More broadly, exemplary bending and the exemplary set are at least 60° or at least 80°.
- the backlocking of the insertion portion 222 with the projection may have one or more of several advantages. Relative to closures using a frame to mount to the tub, material consumption may be reduced in that the projection and wall 80 may involve less material than the frame. The retention of the insertion portion 222 to the tub may be stronger than the frame to the tub, thus improving child-resistance.
- FIG. 3B shows the clasp 34 as having a flower forward tab 320 for user thumb depression.
- an upward projection 324 is received in a downwardly-open channel 326 at the top end of the button 32 (shown overlapping rather than captured due to computer modeling in relaxed conditions).
- a lower end of the button 32 merges with the body sidewall. Capturing of the clasp projection 324 by the channel 326 resists inward depressing of the button 370 .
- Downward pressing of the tab 320 with sufficient force can sufficiently downwardly flex (e.g., twist or rack) sidewalls 328 of the clasp to downwardly shift the projection 324 fully out of the channel 326 or sufficiently out of the channel to allow the button 32 to be depressed, so that the channel 326 no longer blocks upward movement of the projection 324 .
- the container may be hinged open.

A latch 30 (FIG. 3B ) may be formed on the lid and frame (e.g., including abutton 32 of the frame and aclasp 34 of the lid). The latch may be a child-resistant latch. -
FIG. 3 shows theexemplary container interior 38 as containingcontents 40. In one example the contents are laundry detergent pods (e.g., liquid or gel detergent encapsulated between sheets of water-soluble outer skin). -
FIGS. 9-12 show the tub/body 22 in an as-molded condition (but after removal of molding gates, flash, and the like). The exemplary tub has a base 50 (FIG. 10 ) and asidewall 52 extending upward from the base to arim 54. The exemplary tub is of slightly rounded rectangular planform so that, for ease of reference, the four sides are a front 56 (FIG. 10 ), a back 58 (FIG. 9 ), a left side/end 60 (FIG. 10 ), and a right side/end 62 (from the point of view of the container rather than someone facing the container). Near therim 54, the sidewall branches with an inner wall as a continuation of a main portion of the sidewall and anouter wall 64 extending upward from a junction therewith. The outer wall 64 (FIG. 9 ) extends to arim 66 and defines achannel 68 between the inner wall and outer wall. - The outer wall and/or inner wall may bear features for cooperating with the
closure 24. As is discussed further below, these features include awall 80 extending outward from theouter sidewall 64 to define an open-bottom slot orpocket 82 along the rear/back of thebody 22 for receiving an insertion portion of theliving hinge member 26. These cooperating features also include detent features 86 (FIG. 9 ) for cooperating with complementary features of thelid portion 28. - The
sides sidewall 52 meet at generally vertical junctions/corners of thesidewall 52. Theexemplary sidewall 52 has a pair of finger reliefs 72 and 74 (FIG. 10 ) extending along the front corners. These allow gripping by the user (e.g., between thumb and forefinger). -
FIGS. 4-6 show thecover 28 in an as-molded condition.FIGS. 7 and 8 show the cover with the hinge insertion portion bent downward. Thecover 28 extends upward from a lower rim 200 (FIG. 5 ). In the exemplary embodiment, the cover includes awall portion 202 extending upward from therim 200 to ashoulder 204. Atop web 206 extends across from the shoulder to enclose the cover. Thehinge member 26 extends from the shoulder along a rear end of the lid. As is discussed further below, the hinge includes a reduced thicknessflexible portion 220 between theshoulder 204 and aninsertion portion 222 for receipt in thepocket 82. Theinsertion portion 222 comprises a frame 230 (FIG. 4 ) having a pair of sides orarms lower portion 236 joining the two. An opening oraperture 238 is defined between thelower portion 236, anupper portion 240, and theside portions barb portion 250 extends from a root at thelower portion 236 to afree end 252. - In the as-molded condition, the
insertion portion 222 sticks generally straight out parallel to but offset from theweb 206 upper surface. Thepawl 250 extends back toward theflexible portion 220. Thepawl 250 has a proximal portion 260 (FIG. 5 ) joining the frame and extending partially downward and inward therefrom in the as-molded condition and adistal portion 262 extending to theend 252. After molding, theinsertion portion 222 may be bent 90° (to theFIGS. 7 and 8 condition) about an approximate transverse axis of theportion 220 for insertion into the pocket. This transverse axis effectively forms a hinge axis when the cover is installed. -
FIG. 3A shows thehinge insertion portion 222 installed.FIGS. 3, 3A, and 3B reflect artifacts of computer modelling in that some features are shown overlapping due to the software's inability to model the deformations they experience. - In
FIG. 3A , thefree end 252 of the pawl forms an upper edge in this orientation captured beneath the underside of anoutward projection 270 at the upper edge of a slightly vertically recessed portion of theouter sidewall 64. An upper surface of theprojection 270 abuts the edge (lower edge in installed condition) of the frameupper portion 240. Accordingly, it can be seen that when thehinge insertion portion 222 is inserted via downward movement, thelower portion 236 initially passes between arear end 276 of theprojection 270 and a forward face of thewall 80. Further downward movement brings therear end 276 into contact with the adjacent face of the pawl along theproximal portion 260. This produces a force on the pawl flexing the pawl rearward to allow theinsertion portion 222 to pass further downward. Eventually, thefree end 252 of the pawl passes just below theprojection 270 and snaps forward captured in the notch between the underside of theprojection 270 and the outer surface of theouter sidewall 64. At this point, the lower edge of the now downwardly-directed frameupper portion 240 abuts the top surface of theprojection 270 to prevent further downward movement. In this way, the pawl becomes backlocked to prevent nondestructive removal of the lid absent manipulation from below such as with a tool.FIG. 3 shows anapproximate hinge axis 500. As noted above, the hinging may be about multiple parallel instantaneous axes of rotation about the location shown depending upon the state of opening/closing. - As noted above, the hinge may be pre-bent to ease assembly. In one example, the hinge is bent to take an at least temporary set of 90° (the
FIGS. 7 and 8 condition) so that a horizontally-oriented lid may be shifted straight downward to install, simultaneously inserting the hinge member and latching the latch. Depending on the product involved, this may be pre-filling or post-filling of the contents. - Bending may be greater than 90° to provide the 90° set after partial relaxation when the bending moment is removed. More broadly, exemplary bending and the exemplary set are at least 60° or at least 80°.
- The backlocking of the
insertion portion 222 with the projection may have one or more of several advantages. Relative to closures using a frame to mount to the tub, material consumption may be reduced in that the projection andwall 80 may involve less material than the frame. The retention of theinsertion portion 222 to the tub may be stronger than the frame to the tub, thus improving child-resistance. - To complement that child-resistance, the latching mechanism may be child-resistant.
FIG. 3B shows theclasp 34 as having a flowerforward tab 320 for user thumb depression. - Behind the tab, an
upward projection 324 is received in a downwardly-open channel 326 at the top end of the button 32 (shown overlapping rather than captured due to computer modeling in relaxed conditions). A lower end of thebutton 32 merges with the body sidewall. Capturing of theclasp projection 324 by thechannel 326 resists inward depressing of the button 370. Downward pressing of thetab 320 with sufficient force can sufficiently downwardly flex (e.g., twist or rack) sidewalls 328 of the clasp to downwardly shift theprojection 324 fully out of thechannel 326 or sufficiently out of the channel to allow thebutton 32 to be depressed, so that thechannel 326 no longer blocks upward movement of theprojection 324. Thus, with thebutton 32 depressed, the container may be hinged open. - One or more embodiments of the present invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. For example, when implemented in the modification of an existing container configuration, details of the existing configuration or its use may influence details of any particular implementation. Accordingly, other embodiments are within the scope of the following claims.
