20080230569 | Package comprising push-pull closure and slit valve - 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. | 09-25-2008 |
20090212078 | Valve mounting assembly with slit misalignment prevention feature - A mounting system is provided for mounting a valve for accommodating the flow of fluent a substance from a supply of the fluent substance wherein the valve includes a peripheral attachment portion, an intermediate portion extending from the peripheral attachment portion, and a flexible, resilient head that extends from the intermediate portion and that has (a) a first side, (b) a second side, (c) at least one self-sealing slit through the head, (d) a laterally marginal portion adjacent the intermediate portion, and (e) confronting, openable portions along the slit to define an initially closed orifice. The mounting system includes a retention structure for engaging holding the valve and includes an abutment structure. The abutment structure is adapted to be disposed adjacent the valve intermediate portion so that the abutment structure can be engaged by the valve head first side at the laterally marginal portion of the valve head to limit movement of the laterally margin portion of the valve head in one direction. | 08-27-2009 |

20150375907 | Liquid Dispensing Device - A liquid dispensing device for allowing a user to drink liquid therefrom in a hands-free manner. The liquid dispensing device includes a container having a spring-loaded stopper therein, and further including an elongated tube having a mouthpiece thereon that extends from an end of the container. In operation, a user can fill the container with a liquid causing the spring loaded stopper to retract so that it is under tension. When the user wishes to drink the liquid, the user can bite the bite valve of the mouthpiece which enables water to be released from the container and into a tube connected to the mouthpiece. The spring pushes the stopper towards the mouthpiece and thus the liquid within the container is pushed through the tube to the mouthpiece so the user may drink therefrom. | 12-31-2015 |
20160001936 | CLOSURE ASSEMBLY FOR SQUEEZE BOTTLE COMPRISING A THERMOPLASTIC VALVE - A closure assembly includes a valve for containing a substance in a squeeze bottle, a multi-layer material for providing a valve for such a closure assembly, a method for providing such a multi-layer material and a method for providing such a closure assembly. The closure assembly includes a closure cap with a cap part and a body part, a valve arranged in the body part of the closure cap, and an induction element. The induction element is arranged in the closure cap body part for induction sealing a loop shaped peripheral section of the valve to a loop shaped attachment surface of the closure cap body part. | 01-07-2016 |
