- The subject matter disclosed herein relates to flexible sheet dispensers and, more particularly, to a dispensing mechanism for flexible sheets.
- Flexible sheet containers are well known and are used to store and dispense a wide range of products such as baby wipes, cleaning cloths, and the like. The flexible sheet containers come in a variety of shapes and sizes and provide a convenient means to have flexible sheets, such as wipes, readily available. Certain flexible sheet containers include a large opening that enables a user to simply peel off a flexible sheet as needed. In other cases, the flexible sheet container includes an opening having a mechanism for retaining the flexible sheets. That is, as sheets are drawn through the opening, the mechanism provides some resistance. The mechanism grips a subsequent sheet as a sheet is being withdrawn. In this manner, the subsequent sheet is readily available.
- The mechanism for retaining the flexible sheets must serve a dual purpose, first, providing access to the flexible sheet container to enable retrieval of an initial sheet or perhaps a stuck sheet, while also providing resistance on the sheets being withdrawn from the flexible sheet container. At present, these mechanisms take on a variety of forms. One form includes a slit created in a top portion of the flexible sheet container. The slit is usually formed in somewhat flexible material and is sized to enable one or more fingers to access the flexible sheet container. Side portions of the slit come together to grip the flexible sheets. In some cases each side portion includes a cut-out section that forms an opening that is configured to receive the flexible sheet. In other forms, the mechanism includes first and second winged portions that are pivotally mounted on the flexible sheet container through a living hinge. The winged portions are configured to deflect inward to provide access to the containers. When a flexible sheet is withdrawn, the wing member pivots together to provide resistance. In this manner, the wing member grips subsequent sheets. Often times, each wing member includes a cut-out portion that defines an opening for receiving the flexible sheets.
- According to an embodiment of the invention, a dispenser includes a plurality of walls that define a cavity configured to receive a plurality of flexible sheets, where at least one of the plurality of walls defines a dispensing opening. A dispensing mechanism is disposed at the dispensing opening, the dispensing mechanism having a first hinged flap and a juxtaposed second hinged flap, the first hinged flap having a first hinge with first and second opposing faces, and the second hinged flap having a second hinge with first and second opposing faces. At least one of the first hinge and the second hinge having at least one protrusion that extends from a respective first opposing face to make contact with a respective second opposing face when a flexible sheet is dispensed from the cavity, the at least one protrusion limiting pivotal movement of the respective hinge in one direction.
