MODES FOR CARRYING OUT THE INVENTION

Referring now to Figs. 1 - 7, a first embodiment of wet wipe wall mount dispenser constructed in accordance with the teachings of the present invention is illustrated.

The dispenser includes a wall mounting bracket 10, a support lid assembly 12 and a tub assembly 14. The tub assembly 14 includes a tub 16 for holding serially connected wet wipes in wound condition and a tub cover 18 having a tethered removable tub cover lid 19. Tub cover 18 defines an opening 20 in communication with the tub interior receiving the tub cover lid 19. A restrictor plate or sheet 22 (Fig, 7} partially covers the opening 20 and defines a restricted wet wipe passageway 24 through which a topmost wipe is pulled and separated from the wipe stack in known fashion. Fig. 1 shows a wet wipe 26 projecting from the tub cover opening.

The tub cover 18 (see Fig. 7) has three slots 28 formed therein which form part of an interlock system of the wet wipe wall mount dispenser. Fig. 7 also shows ramps 31.

The support lid assembly 12 incorporates two components - a primary lid component 30 and a secondary lid component 32. Ramps 33 (see Fig. 5) on primary lid component 30 cooperate with ramps 31 to help push the tub assembly 14 away from the support lid assembly. The primary lid component incorporates stub shafts 36 which fit into two elongated slots 38 formed in flanges 40 of the wall mounting bracket. Interlock tabs 29 forming the interlock system along with slots 28 project downwardly from the top of the primary lid component 30. The secondary lid component incorporates flanges 42 defining apertures which also receive stub shafts 36. Thus, the secondary lid component is pivotally movable relative to the primary lid component (and relative to the wall mounted bracket) between an open condition (shown in Figs. 1 and 2) and a closed position shown in Fig. 3. Fig. 4 shows the secondary lid component in closed condition relative to the primary lid component and, in the absence of the tub assembly, extending downwardly to form a compact configuration with the wall mounting bracket.

When connecting the tub assembly to the support lid assembly, the tub cover lid 19 is folded backward out of the way (see Fig. 3) prior to engaging the interlock structure previously described.

The wall mounting bracket 10 includes protrusion 48 having a jam contact surface and a lower protrusion 49. The primary lid component 30 has a locking rib 50, the latter being located below slots 38 (see Figs. 5 and 6) . These structural elements cooperate to provide a hinge stop to hold the support lid assembly 90 degrees to the wall for easier installation of the tub. The protrusions 48, 49 and locking rib enable the secondary lid component to move between open and closed position and also the combined primary lid component and secondary lid component to move together with those components in closed relationship to the position shown in Fig. 4.

A curved rib 54 at the bottom of the wall mounting bracket is used to support the tub assembly and also to limit the load on the hinges and the hinge stop structure. It is also allows the option of not using a hinge stop, so that the support lid assembly would automatically collapse when the tub is removed. The arrangement shown requires the support lid assembly to be lifted before it can be pivoted to the collapsed position.

Figs . 8 - 11 show a second embodiment of the invention including a wall mounting bracket 60, a support lid assembly 62 and a tub assembly 64. In this embodiment the support lid assembly is a band 66 having mounting stub shafts 68 positioned in elongated slots 70 of the wall mounting bracke . In this instance the tub assembly 64 is supported by the band being engaged by the tub cover 72 and the two are keyed to provide a proprietary interconnection. A female key 80 is shown in Fig. 11 and a male key 82 on tub cover is shown in Fig. 8. The tub lid 74 of the tub cover assembly that is normally used to close the top of the tub when not in use can be employed rather than utilizing a secondary lid component as is the case in the first embodiment. Fig. 9 shows the tub lid 74 open and Fig. 10 shows the tub lid 74 closed.

Referring now to Figs. 12 - 18, a third embodiment of wet wipe wall mount dispenser constructed in accordance with the teachings of the present invention is illustrated.

The dispenser includes a wall mounting bracket 90, a structural assembly in the form of a support lid assembly 92 and a tub assembly. The tub assembly includes a tub (not shown) , which could be of any suitable type, for example a tub the same as or similar to tub 16 of the first embodiment of this invention described above, for holding serially connected wet wipes in wound condition and a tub cover 98 (shown in Fig. 15 only) which may have a tethered removable tub cover lid (not shown) , for example a cover lid which may have the same as or be similar to cover lid 19 of the first embodiment. Tub cover 98 defines a restricted wet wipe passageway 100 through which a topmost wipe is pulled and separated from the wipe stack in known fashion.

The tub cover 98 (see Fig. 15) has three slots 102 formed therein which form part of an interlock system of the dispenser. The interlock system is described in more detail below.

The support lid assembly 92 incorporates two components - a primary lid component 104 and a second lid component 106. The primary lid component 104 incorporates outwardly directed stub shafts 108 which fit into two elongated slots 110 formed in flanges 112 of wall mounting bracket 90. Fig. 12 illustrates only one of the pair of slots and stub shafts. Interlock tabs 114 forming the interlock system of the dispenser along with slots 102 are disposed at the distal end of a cylindrically shaped boss 116 attached to and projecting downwardly from the primary lid component 104. The boss is open at both ends, forming a primary lid component opening .

A physical characteristic {in this instance the shape) of one of said slots varies from the shapes of the other of said slots. The shapes of the interlock tabs also vary correspondingly whereby a keying function is provided by the slots and interlock tabs.

The secondary lid component 106 incorporates flanges 118 having outwardly directed stub shafts which go into slots 109 of the primary lid component 104, one of the slots 109 being shown in Fig. 12. Thus, the second lid component 106 is pivotally movable relative to the primary lid component and relative to the wall mounted bracket between an open condition (shown in Fig. 17) and a closed position shown in Figs 13 - 16. Fig. 13 shows the second lid component in closed condition relative to the primary lid component and, in the absence of the tub assembly, extending downwardly to form a compact configuration with the wall mounting bracket 90. The secondary lid component is continuously biased to closed position by a spring 119 which in this instance is a deformable spring strip of metal or plastic, for example, affixed to the primary lid component and bearing against the proximal end of the secondary lid component. Seal ring 120 of the secondary lid component and seal ring 122 of the primary lid component form a substantially air tight seal when the seal rings are fully engaged as shown in Fig. 16, for example.

Fig. 14 shows the support lid assembly in its compact configuration supported by a support base 130 which may optionally be employed to provide support for the tub. See Fig. 18. The upper end 132 of the base is inserted into an elongated opening 134 formed at the lower end of the wall mounting bracket and releasably attached in place by any suitable connector structure, for example a snap fit arrangement .

In this embodiment of the invention, there is no structure incorporated in the support lid assembly or bracket to releasably lock the support lid assembly in horizontal position. In the absence of a tub cover and tub being in operative position or the support lid assembly being held up manually, the support lid assembly will move under the influence of gravity to its vertical orientation. However, when a tub cover with tub are attached pivoting downward movement of the support lid assembly is prevented.
