The present invention relates to dispensers for wet wipes. More particularly, the present invention relates to dispensers for heated wet wipes. More particularly, the present invention relates to dispensers for heated baby wipes and the like.
Wet wipes have become a staple article of commerce in connection with their use for numerous cosmetic, personal and household applications, including use as baby wipes and the like. The packaging and dispensing of wet wipes has developed in numerous directions including portable dispensers, both hard and soft containers, and many dispensers which are available in different shapes, size and forms, both heated and unheated. In a number of these dispensers the accessiblity of the wipes themselves is not readily obtained, and in many of these applications, such as with various pop-up dispensers, even though these dispensers are designed and intended to be used for the individual removal of these wipes, the first available wet wipe tends to dry out, particularly when not subject to immediate use. This, in turn, eliminates the entire purpose of wet wipes, producing dryer, less comfortable and less efficient products.
In many cases these wet wipes are sold in containers, including both flexible and rigid containers, and the solvent or other liquid contained within the wet wipes is unevenly distributed in these containers. Thus, the wipes at the bottom of the container are far wetter than the wipes at the top of the container, and in fact in some cases users have tended to invert the containers and leave them in that condition for a period of time in order to more evenly distribute this liquid throughout the container.
In addition, in many of these wet wipe dispensers, and particularly the pop-up dispensers, although they are specifically designed so that with the removal of each wet wipe the next succeeding wet wipe will be pulled into a dispensing slot for subsequent removal, during use in many case the initial wet wipe will fall back into the container, thus creating inconvenience, and the need for manual manipulation in order to obtain the upper wet wipe and withdraw it into the dispensing slot.
The nature and variety of various wipe dispensers is, as mentioned above, quite extensive. Examples by the assignee of the present application include U.S. Pat. Nos. 5,647,506 and 5,542,468, which are only two of the many commercially important products which have been developed. These also include products with refillable dispensing systems, such as in U.S. Pat. No. 6,412,634, and systems which dispense continuous webs of material which are joined by perforations and are dispensed from a continuous roll such as those described in U.S. Pat. No. 6,578,731, and others.
There are also some instances in which dry wipe dispensers have been designed for downward removal of an initial wipe from a vertically disposed wipe dispenser kit. Thus, the product shown in U.S. Pat. No. 6,585,130 is mounted by means of a hook attached to an outside surface. However, the product shown in this patent is specifically designed for the dispensing of dry wipe products, and the wipes are not arranged to be separately removed through a dispensing slot. To the contrary, they are specifically arranged for grasping by the user in order to effectuate each separate removal step. Also, this device is not removably or temporarily mountable upon a surface for the ready removal of individual wipes therefrom, and in fact the bottom surface includes the slot for wipe removal and therefore could not possibly be mounted on a surface selected by the user.
In addition, there are a number of heated wipe dispensers which are known in the art in which the wipes are separately removed in an upward direction from the top of a dispenser. For example, Japanese Patent No. JP 8-11737 (see FIG. 13 of U.S. Pat. No. 6,331,696) discloses a prepackaged wet tissue warming apparatus with electrical heating elements heating the wet tissues closest to the dispensing surface so as to provide for those tissues to be heated more thoroughly than those further from the dispensing surface. The surface also includes a cover which can be opened to remove the wet tissues and means for aiding in dispensing by utilizing coil springs to exert pressure upon the plate supporting the wet tissues.
There are many other configurations of wet wipes and the like which are disposed in a heated dispenser for upward removal in the prior art. These include, for example, the aforementioned U.S. Pat. No. 6,331,696, disclosing a device for warming prepackaged pre-wetted towels including a coil spring shown in FIG. 2 thereof to aid in dispensing. Also, U.S. Pat. No. 4,694,973 uses light bulbs as the heating element therein, and U.S. Pat. No. 5,210,396 discloses a baby wipes warmer apparatus which includes a container assembly to receive a box of baby wipes and a heater assembly with an electrical heating element with preselected heating conditions.
The search has thus continued for a more convenient and efficient dispenser for wet wipes which can not only provide a free-standing dispenser which is readily usable for individual selective removal of wet wipes when mounted on a surface selected by the user, but which also maintains these wet wipes in a configuration which keeps the leading wet wipe for removal in a wet or moist condition while permitting such ready removal, and which in a preferred embodiment also provides for heating the wet wipes as they are removed from the container, which is also preferably one which can be refilled in a simple manner.

A typical container of wet wipes for use in connection with the dispenser of the present system is shown in
The first member 10 in the embodiment shown in
As can be seen in
The dispenser shown in
The lower member 2 and the upper member 4 are also connected to each other. In the embodiment shown in
As can be seen in
In a preferred embodiment, a torsion spring 20 can be affixed to the lower portion of the hinge 6 so as to pivotally urge the upper end of the hinge 6 downwardly against the upper surface of the upper member 4 such as by merely surrounding the pivot pin 22, so that the hinge 6 will cause the upper member 4 to exert pressure on the bottom surface of the container of wet wipes disposed between the upper member 4 and the lower member 2.
As can be specifically in
Although this embodiment is shown with the use of pivot pins, there are a number of other alternative assemblies which can be used to an equivalent effect. For example, in one embodiment, a flexible strap can be secured to the upper member and the lower member, allowing both pivotable movement of the upper member relative to the lower member, as well as dynamic separation between the two members. Other such assemblies are also possible.

In a preferred embodiment of the present invention, at least one heater 64 is imbedded, preferably within the first member 10, for the purpose of ensuring that the leading wet wipes, as they are individually removed from the dispenser, are not only properly moistened, but are also heated to the proper temperature. A number of such heater(s) can also be imbedded therein if desired. In general, the heaters are preferably symmetrically or asymmetrically distributed on the sides of the open area or slot 8, and may also be disposed on the upper surface 48 of the first portion 10, or on the opposing surface of first portion 10. Coiled resistance heaters are shown in
In the embodiment shown in
In another embodiment where a switch is not used, current can still be passed through heater 64 by means of a line cord when the cord is plugged into an electrical outlet regardless of whether a package is present within open area 8.

As is discussed above, the presence of a spring 20, or other such means for creating pressure on the upper member 4, can create additional downward force upon the bottom surface 86 of the package 82. It is not necessary to use a spring to accomplish this result, and the weight of the upper member 10 itself, or added weight thereto, can create the same effect. As can thus be seen in
