  • Package comprising push-pull closure and slit valve
    Patent number: 7874466
    Abstract: Packages for containing and dispensing consumer products comprise a push-pull closure connected to a bottle and having a dispensing opening covered by a slit valve. The combination of a push-pull closure and a slit valve results in a package that easily dispenses a liquid consumer product, while guarding against leakage of the consumer product from the package, especially during transportation and storage of the product, particularly when the package is a tottle package. The push-pull closure of the present package is simple to open and can also be easily closed with the use of only one hand, especially by pressing the closure against a flat surface, such as a shower wall or shelf.
