  • Patent number: 4172540
    Abstract: A dispensing closure having a cap with an opening extending through the top of the cap and having a lid mounted on the cap so that it is capable of being moved between a closed position in which the lid closes off the opening and an open position in which the opening is exposed can be constructed so as to utilize a spring mounting the lid on the cap. One of the ends of the spring employed is secured to the cap so that the spring is incapable of being pivoted relative to the cap while the other of the ends of the spring is pivotally connected to the lid. The spring is connected to the lid at a location such that the spring has to be bent and such that the lid has to be pivoted relative to the spring in order for the lid to be moved between the noted open and closed position. The spring serves to hold the lid relative to the top of the cap so that the lid is held against movement in the open position by the spring.
