Abstract
A waste container has a base and a lid. The lid is connected to the base by a coil spring hinge that biases the lid to an open condition. A latch mechanism includes a deformable wall section on the lid and a pivotable latch member on the base with a curved end to effect a force fit therebetween when the lid is closed and pressed downwardly. Movement of the latch disengages the base latch member from the lid wall section and starts movement of the lid in a direction to open it. Further, lid movement towards an open position is then caused by the spring hinge to fully open the lid.
Description
2~2840 7713/~1 INDOOR WASTE CONT~TN~R WITH SPRING ACTUATED LID
Field of the Invention:
The invention relates to a waste container with a lid activated by a spring and a latching mechanism to hold the lid closed.
Background of the Invention Waste containers are used for a variety of purposes, both indoors and outdoors. One typical use is in a kitchen or other indoor environment. Such a waste container for indoor use often has both a base and a lid. In many types of such containers, the lid is a separate cover piece that is removed from and replaced onto the base. In other types, the lid is hingedly connected to the base and a hand or foot operated pedal raises and lowers the lid via a mechanical connection.
While all of such containers are usually adequate for their intended purpose of storing waste in the container base, some are relatively costly and complex. For example, a container with a foot-operated pedal requires a relatively complex and expensive mechanism to raise and lower the lid. Therefore, it is desired to provide containers that are efficient from the ~-i 8Z~4~
point of view of connecting the lid to the base, and are easy to operate, easy to manufacture, and therefore of low cost.
Brief Description of the Invention The present invention relates to a waste container having a lid that is hinged to the base by a simple coil spring that biases the lid to a normally open position. A latch mechanism is provided to hold the lid in a closed position to cover the open top of the base.
The latch mechanism includes a latch pad with a hook that is pivotably mounted to the base. The lid has a rim that includes a crenelated, deformable wall section aligned with the latch pad hook. Pressing the lid downwardly against the force of the spring brings the latch hook and crenelated wall section into an engaging force fit that keeps the lid closed on the top of the base. Pressing downwardly on the latch pad disengages the hook from the crenelated wall and gives a slight movement to the lid toward an open condition. The force of the spring takes over to move the lid to its finally open position.
The container of the invention is effective in its operation and of relatively simple construction.
Objects of the Invention An object of the invention is to provide a waste container of relatively simple construction having a hinged lid.
A further object is to provide a waste container with a hinged lid including a spring that biases the lid to an open position and a latch mechanism to hold the lid closed.
Yet another object is to provide a waste container with a spring loaded lid and a latch mechanism provide by a pivotable hook on the container base that makes a force fit engagement with a part of the lid.
A further object is to provide a waste container with a spring loaded lid in which activation of a latch pad disengages a latching force fit between the container lid and its base.

Detailed Description of the Invention Referring to the drawings, as shown in Fig. 1, the container has a base 10 having the general shape of a sector of a circle. That is, the base vertical rear wall 12 is elongated and gently curved. The vertical front wall 14 is approximately a sector of a circle. The rear and front walls 12, 14 are continuous.
Container base 10 is preferably injection molded in one piece of a suitable thermoplastic material such as polyethylene, polypropylene, ABS, etc. The size of the base is selected as desired. The walls of base 10 are slightly tapered inwardly so that a number of bases can be stacked for manufacturing and shipping purposes. As seen in Fig. 1, for primarily decorative purposes, a curved depression 16 extends vertically along a part of the base front wall 14.
At the top of the base 10 is a peripheral band 20 which extends outwardly of the vertical walls 12 and 14 and completely around the top of base 10. The height of the band 20 can be of any desired size, and is usually selected for a combination of base strength and aesthetic purposes. Inward of the outer surface of band 20 is a vertical wall 24 that terminates in an upper edge 22. The band upper edge 22 is spaced inwardly from the band 20 outer surface and there is a chamfer 23 between the upper edge 22 and the band outer surface. At the lower edge of vertical wall 24 is a generally horizontal peripheral ledge 26.
The ledge 26 is spaced downwardly from the band edge 22 by an amount corresponding to the height of a peripheral lip of the lid, to be described.
2l~2s~a On the top edge of the band 20 of the base rear wall 12 are a pair of spaced upstanding generally triangular hinge mounting shoulders 28. Each shoulder 28 has a slot 29 (see Fig.
4) in its inner face for receiving a hinge pin from the lid, to be described.
In the front wall 14 portion of the band 20 is a semi-elliptical, or scalloped, seat 30 that extends inwardly of the base. Seat 30 has a reinforced curved vertical inner wall 31, reinforced vertical side walls 36 (see Fig. 2) and a bottom wall 32 that define a cavity 33 for a movable latch release pad 34.
Latch release pad 34 has a shape corresponding to that of the cavity 33. The base latch pad cavity 33 opposed vertical reinforced side walls 36, each have a hole 37 therein, as seen in Figs. 3, 5 and 6. The latch pad 34 has vertical end walls 35 from each of which extends a hinge pin 41. The latch pad hinge pins 41 fit into the holes 37 of the cavity walls 36 (see Fig.
2) . Accordingly, the latch pad 34 is pivotal up and down relative to the bottom wall 32 of the latch pad recess 33.
The container also includes a lid 50 of a shape corresponding to and somewhat smaller than the base band 20 interior peripheral vertical wall 24. Lid 50 has a flat section 52 and an extending downwardly sloping surrounding outer wall 51 that terminates in a downwardly extending peripheral rim 55. The height of lid rim 55 approximately corresponds to the depth of the base band interior vertical wall 24, that is, from the base band upper edge 23 down to the band interior surrounding horizontal ledge 26. The front part of the lid has a scallop shaped cut out 54 that corresponds to and is somewhat larger than 2182~4~
the base latch pad seat 30 inner curved wall 31. The size of the lid is such as to fit within the peripheral vertical wall 24 of base band 20 with the lower surface of its rim 55 touching the base band horizontal peripheral wall 26.
Referring to Figs. 3, the rear part of the lid 50 has a downwardly sloping section 58 that extends from the lid flat top section 52. A flat 57 extends rearwardly from the sloping section 57 and a downwardly extending skirt 56 projects from flat 57. Skirt 56 is generally perpendicular to the lid flat top section 52. As seen in Fig. 2, the flat 57 and downwardly extending skirt 56 have a length somewhat less than the spacing between the opposing inner faces of base hinge shoulder 28.
A wall 59 (see Figs. 1 and 2) projects inwardly of the lid from each end of the junction of the flat 56 and skirt 56.
The walls 59 are generally transverse to the skirt 56 and parallel to the inner faces of the base hinge mounting shoulders 28. A hinge pin 61 projects outwardly from each end wall 59 to fit into a corresponding slot 29 of the hinge mounting shoulder 28 (see Fig. 4). This permits the lid to pivot between open (Fig. 1) and closed (Fig. 2) positions. The placement of the lid hinge pins 61 relative to the slots 29 of the base hinge mounting shoulders 28 is such as to permit the bottom of lid skirt 56 to clear the top of the base band 20 as the lid opens and closes.
Lid skirt 56 has an L-shaped slot 70 near its center.
A mounting recess 72 is formed on the interior of the lid sloping section 51 and a recess 74 is formed on the interior of the base band 20. A coil spring hinge 76 has its central coil part in the short leg of lid skirt wall slot 70 and a respective end leg 72a 21828~
and 74a in each of the recesses 72 and 74 (see Fig. 7). Each spring end 72a and 74a can have a generally rectangular piece or bracket fit in the respective recess 72, 74. This stabilizes and supports the spring legs. As mounted, the coil spring 76 is of a type that exerts a force to hold the lid 50 in an open position.
The end of the latch pad 34 (see Figs. 3, 5 and 6) is formed with an integral L-shaped hook 42 that is transverse to the pad. The front end 43 of the hook has a flat surface 45 transverse to and wider than the hook. The hook flat surface 45 terminates in a downwardly tapered or curved front end 46.
The front scallop 54 of the lid peripheral rim 55 has a separate section 64 (see Fig. 1) with a crenelated, or V-shaped, wall (Figs. 3, 5 and 6) with a downwardly extending apex 66. The crenelation 64 is aligned with the latch pad 42 hook front end 45 at the center of the crenelation 64 when the lid is closed.
The lid 50 is also preferably molded in one section from any suitable thermoplastic material. The lid latch pad 34 and its integral hook 42 are also molded of any suitable thermoplastic material, such as polypropylene, which is "harder"
than the lid material, especially the material of the crenelated section 64.
Operation of the invention is as follows. The lid 50 is shipped separately from the base 10. It is assembled to the base by inserting the hinge pins 61 into the openings 29 of the base hinge mounting shoulders 28. The spring 76 is then placed 21 8284~
in lid skirt 56 opening 70 and its legs 72a and 74a placed in the respective slots 72 and 74.
When it is desired to close the container, the lid is lowered by user applying direct movement against the force of spring 76. As the lid is pressed downwardly the lid rim 55 sits within the peripheral vertical wall 24 of the base band 20. As seen in Fig. 5, the apex 66 of the lid crenelated wall section 64 engages the curved front portion 46 of the latch pad hook 42.
The engagement is a type of wedging action, or force fit. That is, the hook front end depresses or deforms the material of the lid crenelated section. This holds the lid in a closed position against the force of spring 76 and also causes the latch pad 34 to pivot slightly upwardly about its hinge pins 37 (counter clockwise in Fig. 5).
When it is desired to open the lid, the user pushes down (see Fig. 6) on the top of latch pad 34. This pivots the hook 42 and its curved flat end 46 upwardly as the latch pad 34 pivots clockwise around its hinge pins 37. Upward movement of the hook end 46 breaks (detaches) the fastening engagement between the apex 66 of the lid crenelation 64 and the sloping surface 46 of the hook. It also imparts a slight upward movement to the lid 50 to start to move it to an open position. There is then continued movement of the lid 50 by the force of spring 76 to raise it to its fully open position.
As seen, a container is provided with a base that has a pivotable lid attached by a hinge with a spring that normally holds the lid open. A latching mechanism holds the lid closed and actuation of the latching mechanism causes the lid to 2~8~
automatically assume a fully open position under force of the spring. The attachment and operation of the lid opening and closing is simple, efficient and is relatively inexpensive.

The invention relates to a waste container with a lid activated by a spring and a latching mechanism to hold the lid closed.

Detailed Description of the Invention Referring to the drawings, as shown in Fig. 1, the container has a base 10 having the general shape of a sector of a circle. That is, the base vertical rear wall 12 is elongated and gently curved. The vertical front wall 14 is approximately a sector of a circle. The rear and front walls 12, 14 are continuous.
Container base 10 is preferably injection molded in one piece of a suitable thermoplastic material such as polyethylene, polypropylene, ABS, etc. The size of the base is selected as desired. The walls of base 10 are slightly tapered inwardly so that a number of bases can be stacked for manufacturing and shipping purposes. As seen in Fig. 1, for primarily decorative purposes, a curved depression 16 extends vertically along a part of the base front wall 14.
At the top of the base 10 is a peripheral band 20 which extends outwardly of the vertical walls 12 and 14 and completely around the top of base 10. The height of the band 20 can be of any desired size, and is usually selected for a combination of base strength and aesthetic purposes. Inward of the outer surface of band 20 is a vertical wall 24 that terminates in an upper edge 22. The band upper edge 22 is spaced inwardly from the band 20 outer surface and there is a chamfer 23 between the upper edge 22 and the band outer surface. At the lower edge of vertical wall 24 is a generally horizontal peripheral ledge 26.
The ledge 26 is spaced downwardly from the band edge 22 by an amount corresponding to the height of a peripheral lip of the lid, to be described.
2l~2s~a On the top edge of the band 20 of the base rear wall 12 are a pair of spaced upstanding generally triangular hinge mounting shoulders 28. Each shoulder 28 has a slot 29 (see Fig.
4) in its inner face for receiving a hinge pin from the lid, to be described.
In the front wall 14 portion of the band 20 is a semi-elliptical, or scalloped, seat 30 that extends inwardly of the base. Seat 30 has a reinforced curved vertical inner wall 31, reinforced vertical side walls 36 (see Fig. 2) and a bottom wall 32 that define a cavity 33 for a movable latch release pad 34.
Latch release pad 34 has a shape corresponding to that of the cavity 33. The base latch pad cavity 33 opposed vertical reinforced side walls 36, each have a hole 37 therein, as seen in Figs. 3, 5 and 6. The latch pad 34 has vertical end walls 35 from each of which extends a hinge pin 41. The latch pad hinge pins 41 fit into the holes 37 of the cavity walls 36 (see Fig.
2) . Accordingly, the latch pad 34 is pivotal up and down relative to the bottom wall 32 of the latch pad recess 33.
The container also includes a lid 50 of a shape corresponding to and somewhat smaller than the base band 20 interior peripheral vertical wall 24. Lid 50 has a flat section 52 and an extending downwardly sloping surrounding outer wall 51 that terminates in a downwardly extending peripheral rim 55. The height of lid rim 55 approximately corresponds to the depth of the base band interior vertical wall 24, that is, from the base band upper edge 23 down to the band interior surrounding horizontal ledge 26. The front part of the lid has a scallop shaped cut out 54 that corresponds to and is somewhat larger than 2182~4~
the base latch pad seat 30 inner curved wall 31. The size of the lid is such as to fit within the peripheral vertical wall 24 of base band 20 with the lower surface of its rim 55 touching the base band horizontal peripheral wall 26.
Referring to Figs. 3, the rear part of the lid 50 has a downwardly sloping section 58 that extends from the lid flat top section 52. A flat 57 extends rearwardly from the sloping section 57 and a downwardly extending skirt 56 projects from flat 57. Skirt 56 is generally perpendicular to the lid flat top section 52. As seen in Fig. 2, the flat 57 and downwardly extending skirt 56 have a length somewhat less than the spacing between the opposing inner faces of base hinge shoulder 28.
A wall 59 (see Figs. 1 and 2) projects inwardly of the lid from each end of the junction of the flat 56 and skirt 56.
The walls 59 are generally transverse to the skirt 56 and parallel to the inner faces of the base hinge mounting shoulders 28. A hinge pin 61 projects outwardly from each end wall 59 to fit into a corresponding slot 29 of the hinge mounting shoulder 28 (see Fig. 4). This permits the lid to pivot between open (Fig. 1) and closed (Fig. 2) positions. The placement of the lid hinge pins 61 relative to the slots 29 of the base hinge mounting shoulders 28 is such as to permit the bottom of lid skirt 56 to clear the top of the base band 20 as the lid opens and closes.
Lid skirt 56 has an L-shaped slot 70 near its center.
A mounting recess 72 is formed on the interior of the lid sloping section 51 and a recess 74 is formed on the interior of the base band 20. A coil spring hinge 76 has its central coil part in the short leg of lid skirt wall slot 70 and a respective end leg 72a 21828~
and 74a in each of the recesses 72 and 74 (see Fig. 7). Each spring end 72a and 74a can have a generally rectangular piece or bracket fit in the respective recess 72, 74. This stabilizes and supports the spring legs. As mounted, the coil spring 76 is of a type that exerts a force to hold the lid 50 in an open position.
The end of the latch pad 34 (see Figs. 3, 5 and 6) is formed with an integral L-shaped hook 42 that is transverse to the pad. The front end 43 of the hook has a flat surface 45 transverse to and wider than the hook. The hook flat surface 45 terminates in a downwardly tapered or curved front end 46.
The front scallop 54 of the lid peripheral rim 55 has a separate section 64 (see Fig. 1) with a crenelated, or V-shaped, wall (Figs. 3, 5 and 6) with a downwardly extending apex 66. The crenelation 64 is aligned with the latch pad 42 hook front end 45 at the center of the crenelation 64 when the lid is closed.
The lid 50 is also preferably molded in one section from any suitable thermoplastic material. The lid latch pad 34 and its integral hook 42 are also molded of any suitable thermoplastic material, such as polypropylene, which is "harder"
than the lid material, especially the material of the crenelated section 64.
Operation of the invention is as follows. The lid 50 is shipped separately from the base 10. It is assembled to the base by inserting the hinge pins 61 into the openings 29 of the base hinge mounting shoulders 28. The spring 76 is then placed 21 8284~
in lid skirt 56 opening 70 and its legs 72a and 74a placed in the respective slots 72 and 74.
When it is desired to close the container, the lid is lowered by user applying direct movement against the force of spring 76. As the lid is pressed downwardly the lid rim 55 sits within the peripheral vertical wall 24 of the base band 20. As seen in Fig. 5, the apex 66 of the lid crenelated wall section 64 engages the curved front portion 46 of the latch pad hook 42.
The engagement is a type of wedging action, or force fit. That is, the hook front end depresses or deforms the material of the lid crenelated section. This holds the lid in a closed position against the force of spring 76 and also causes the latch pad 34 to pivot slightly upwardly about its hinge pins 37 (counter clockwise in Fig. 5).
When it is desired to open the lid, the user pushes down (see Fig. 6) on the top of latch pad 34. This pivots the hook 42 and its curved flat end 46 upwardly as the latch pad 34 pivots clockwise around its hinge pins 37. Upward movement of the hook end 46 breaks (detaches) the fastening engagement between the apex 66 of the lid crenelation 64 and the sloping surface 46 of the hook. It also imparts a slight upward movement to the lid 50 to start to move it to an open position. There is then continued movement of the lid 50 by the force of spring 76 to raise it to its fully open position.
As seen, a container is provided with a base that has a pivotable lid attached by a hinge with a spring that normally holds the lid open. A latching mechanism holds the lid closed and actuation of the latching mechanism causes the lid to 2~8~
automatically assume a fully open position under force of the spring. The attachment and operation of the lid opening and closing is simple, efficient and is relatively inexpensive.
