The present invention relates to a gum dispenser for automatically dispensing gum by the vertical lifting of a gum case. Particularly, the present invention provides a container that has a self-sealing means, accurately dispenses a piece of gum one by one, prevents the generation of container defects, and provides ease of operation and molding. Currently, in the above operation structure, an inner case receiving gum therein is fitted in a lifting shaft of an outer case to be lifted or lowered so that a piece of gum is pushed up to an upper end of the lifting shaft, and then the gum is exposed to a dispensing hole perforated in a lid, which is coupled with the inner case, one by one for a user to enjoy. The above structure, however, has a disadvantage in that if two pieces of gum are lifted to the upper end of the lifting shaft and the lifting shaft is exposed to the perforated hole of the lid, then the lifting shaft and the dispensing hole correspond to each other 1:1 so that the two pieces of gum pop out, which makes the gum difficult to catch. In addition, if the lifting shaft is molded integrally with the outer case, the lifting shaft is likely to be twisted or bent due to the thickness thereof in the cooling procedure during the molding thereof so that it is difficult to achieve a precisely standing structure. Furthermore, if the inner case is repetitively lifted or lowered in the outer case, an outer force may be applied in the lifting motion according to a vacuum state, so that smooth operation becomes impossible and longer molding time is required in the molding. In addition, in the state that the lid is sealingly coupled with the outer case and the inner case for the sealing of the container during storage or delivery thereof, a perforated lid for implementing the dispensing hole may be pressed by the lifting shaft and the container may burst. If the perforated lid is formed to be thick in order to prevent the bursting, a pulling portion to be pulled for cutting the perforated lid is likely to be cut, and implementation of the dispensing hole may fail. As a result, the present invention is aimed at resolving the above problems.
