DETAILED DESCRIPTION
FIGS. 1 and 2 illustrate an exemplary embodiment of a wet wipes dispenser 100. Wipes dispenser 100 includes a container 102. Located inside of container 102 is a roll of wipes 104. The role of wipes 104 has periodic perforations 140 that are used to separate individual wipes from the role of wipes. In one embodiment, the wipes are individual wipes that are folded together such that the leading wipe pulls the trailing wipe through the opening before the two wipes separate. Wipes dispenser 100 includes a cap 106 secured to container 102. Cap 106 may be secured to container 102 by any means such as, for example, a threaded connection, a welded connection, a snap-fit connection, an adhesive bonding connection or the like.
Cap 106 includes a recessed portion 132 that has an aperture 120 to allow wipes 104a to pass therethrough. In addition, recessed portion 132 has a support ledge 130. Support ledge 130 supports an annular projection 118 of a dispensing nozzle 110.
Dispensing nozzle 110 is made of a resilient material such as, for example, silicon. Dispensing nozzle 110 includes a dome 112 that has a narrow aperture or opening 114 therethrough. Opening 114 has a circular cross-section that may expand as needed to allow the wipe 104a to be pulled through the opening 114. Nozzle 110 includes a fluid retaining member 116. Fluid retaining member 116 is an annular member that has a sloped surface. In one embodiment, the sloped surface traps and holds liquid. As shown, fluid retaining member 116 is integrally molded with dome 112; however, fluid retaining member 116 may optionally be a separate part.
Wipes dispenser 100 includes a retaining ring 136. Retaining ring 136 secures dispensing nozzle 110 to cap 106. Retaining ring 136 is retained with a snap-fit connection by projection 132 on cap 106 and projection 134 on retaining ring 136.
In one embodiment, cap 106 may include a snap cover (not shown). If a snap cover is provided, a hinged member may fit in opening 204 wherein projections extending from the cover fit into apertures 206 so that the cover may rotate. On the other side of the cover would be a snap connector that would snap into slot 202 to maintain the cover in a closed position. In embodiments where no cover is used, opening 204 and slot 202 may be eliminated.
During operation, wipe 104a is pulled up through dispensing nozzle 110. As wipe 104a is pulled up through narrow opening 114 of dispensing nozzle 110, liquid is squeezed or rung out of the wipe 104a. The liquid travels along the inside of dome 112 and runs down to fluid retaining member 116. The liquid contacts a portion of the wipe 104a that is passing by fluid retaining member 116 to re-wet the wipe 104a. Thus, fluid retaining member 116 helps ensure that all of the wipe 104a is wet. In addition, fluid retaining member 116 may hold liquid for a longer period of time and help keep the wipe 104a from drying out between uses. In one embodiment, fluid retaining member 116 and the size of opening 114 combine to eliminate the need for a re-closable cover (not shown) on cap 106.
In addition, during operation when a wipe is pulled through an orifice, liquid is often expelled from the wipe in the form of a spray, especially when the wipe is pulled from the container rapidly. In one embodiment, fluid retaining member 116 prevents the expelled liquid from spraying.
FIGS. 3 and 4 respectively illustrate an alternative embodiment of a dispensing nozzle 310 and a support ring 450 for use with the dispensing nozzle 310. Dispensing nozzle 310 is made of a resilient material such as, for example, silicon. Dispensing nozzle 310 includes a dome 312 that has a narrow aperture or opening 314 therethrough. Opening 314 has a circular cross-section that may expand as needed to allow a wipe 104a (not shown) to be pulled through the opening 314. Nozzle 310 includes a fluid retaining member 316. Fluid retaining member 316 is an annular member that has a non-sloped, horizontal surface. In one embodiment, the horizontal surface 316 traps and holds liquid. As shown, fluid retaining member 316 is integrally molded with dome 312; however, fluid retaining member 316 may optionally be a separate part. Dispensing nozzle 310 has an annular projection 350 underneath the dome 312. The annular projection 350 has an upwardly extending flange 352 on an outer end in order for the nozzle 310 to be received within the support ring 450, as described below.
Support ring 450 has a rim 452 for engagement with a cap (not shown) of a wet wipes dispenser. Support ring 450 includes a central opening 454 to allow wipes 104a to pass therethrough. An annular projection 456 extends down from the rim 452 in order to support the dispensing nozzle 310 within the central opening 454. Annular projection 456 has an inner diameter D1 which is substantially equal to the outer diameter Do of the annular portion 350 of the dispensing nozzle 310 to provide a squeeze fit of the nozzle 310 within the annular projection 456. Annular projection 456 further includes a ring 458 extending inwardly from the annular projection 456 to end at an inner lip 460. Ring 458 and lip 460 form a receptacle 462 which receives the flange 352 of the nozzle 310 in a squeeze fit, helping to secure the nozzle 310 in place. Dispensing nozzle 310 may additionally or alternatively be secured to the support ring 450 by any other means such as, for example, a threaded connection, a welded connection, a snap-fit connection, an adhesive bonding connection, or the like.
As discussed above in connection with the cap 106, the supporting ring 450 may include elements for connecting to an optional snap cover (not shown).
During operation, wipe 104a is pulled up through dispensing nozzle 310. As wipe 104a is pulled up through narrow opening 314 of dispensing nozzle 310, liquid is squeezed or rung out of the wipe 104a. The liquid travels along the inside of dome 312 and runs down to fluid retaining member 316. The liquid contacts a portion of the wipe 104a that is passing by fluid retaining member 316 to re-wet the wipe 104a. Thus, fluid retaining member 316 helps ensure that all of the wipe 104a is wet. In addition, fluid retaining member 316 may hold liquid for a longer period of time and help keep the wipe 104a from drying out between uses. In one embodiment, fluid retaining member 316 and the size of opening 314 combine to eliminate the need for a re-closable cover (not shown) to be disposed over nozzle 310 and supporting ring 450.
In addition, during operation when a wipe is pulled through an orifice, liquid is often expelled from the wipe in the form of a spray, especially when the wipe is pulled from the container rapidly. In one embodiment, fluid retaining member 316 prevents the expelled liquid from spraying.
Although the nozzle embodiments 110 and 310 illustrated herein have a dome shape, other shapes are contemplated such as, for example, a conical shape. In addition, fluid retaining members 116 and 316 may have shapes that are not annular. In one exemplary embodiment, the opening of fluid retaining member 116 or 316 is a longitudinal slit. In another, the opening of fluid retaining member 116 or 316 has a star shape. Other optional shapes include polygonal openings and sinusoidal slits.
