A sealing push-button lid for consumer wipes is disclosed. The lid may be used to seal a package of wipes for infant care, and may also be used for sealing and dispensing of one-at-a-time wipes for general cleaning purposes. The lid makes it easy for a busy person to use a single hand to pop open the lid in order to grasp and dispense the next wipe in a series of Z-folded wipes or inner-folded wipes in a preferably soft and flexible container. Containers with the push button lid may also be used with wipes that are folded in other ways. The lid is formed as one piece or two pieces, the pieces joined by a hinge that allows movement of the lid top with respect to the lid bottom. The lid is designed for easy joining and sealing to a container, preferably by a bead of hot melt adhesive or adhesive strips.

What is claimed is: 1. A plastic container lid, comprising: a plastic lid bottom, comprising a sealing portion and a latching and releasing portion adjacent the sealing portion, the latching and releasing portion flexibly joined to the sealing portion, and the lid bottom having an open central dispensing area, wherein the releasing portion comprises: a plurality of guides, each of which extends outwardly from the releasing portion toward the sealing portion and upwardly from the sealing portion, and each of which is coupled to the sealing portion; and a plastic solid lid top further comprising a catch for mating with the latching portion, the lid top hingedly and flexibly connected to the bottom portion; wherein the guides direct the lid top into releasable interaction with the lid bottom and limit the downward motion of the lid top as the plastic container lid transitions from an open configuration to a closed configuration; and wherein the flexible pivoting of the releasing portion causes the guides attached to the releasing portion to move in an upward direction towards the container lid and urge the container lid away from the container bottom, thereby initiating movement of the plastic container lid from a closed configuration to an open configuration. 2. The plastic container lid according to claim 1, wherein the lid top and bottom comprise mating seals forming at least one seal around the central dispensing area. 3. The plastic container lid according to claim 1, wherein the lid top and bottom comprise mating seals forming at least one seal around the central dispensing area, the seals comprising surfaces raised transverse to flat areas of the lid top and bottom. 4. The plastic container lid according to claim 1, wherein a raised sealing surface of the top portion fits within a raised sealing surface of the bottom area when the lid is closed. 5. The plastic container lid according to claim 1, further comprising a spring between the lid top and bottom, the spring urging apart said lid top and bottom. 6. The plastic container lid according to claim 1, wherein the catch protrudes horizontally from a vertical surface of the lid top and the latching portion protrudes horizontally from a vertical surface of the latching and releasing portion. 7. The plastic container lid according to claim 1, wherein the releasing portion further comprises a gripping portion for a thumb or a finger of a user. 8. The plastic container lid according to claim 1, wherein the lid top and bottom are formed by molding as a single piece with at least one hinge leaf connecting the lid top and bottom. 9. The plastic container lid according to claim 1, wherein the lid top and bottom are formed by molding as two separate pieces and are joined by connecting at least one hinge leaf on one of the lid top and bottom with at least one pivot on the other of the lid top and bottom. 10. The plastic container lid according to claim 1, wherein the container lid is formed by injection molding as a single piece. 11. A plastic container lid, comprising: a plastic lid bottom, comprising a sealing portion and a latching and releasing portion adjacent the sealing portion, the latching and releasing portion flexibly joined to the sealing portion, and the lid bottom having an open central dispensing area, wherein the releasing portion comprises: a plurality of guides, each of which extends outwardly from the releasing portion toward the sealing portion and upwardly from the sealing portion, and each of which is coupled to the sealing portion; a plastic solid lid top further comprising a catch for mating with the latching portion, the lid top hingedly and flexibly connected to the bottom portion; and a spring between the lid top and bottom, the spring urging apart said lid top and bottom wherein the guides direct the lid top into releasable interaction with the lid bottom and limit the downward motion of the lid top as the plastic container lid transitions from an open configuration to a closed configuration; and wherein the flexible pivoting of the releasing portion causes the guides attached to the releasing portion to move in an upward direction towards the container lid and urge the container lid away from the container bottom, thereby initiating movement of the plastic container lid from a closed configuration to an open configuration. 12. The plastic container lid according to claim 11, wherein the container lid is formed by injection molding of polypropylene as a single piece. 13. The plastic container lid according to claim 11, further comprising reliefs on at least one of the lid bottom and lid top, said reliefs in the area of the catch of the lid top and the catching and releasing portion of the lid bottom. 14.
