Description

Container assembly {CONTAINER ASSEMBLY HAVING A COVER CAP PROVIDED WITH A PUMP MEMBER TO PUMP OUT AIR FROM A CONTAINER}

The present invention relates to a container assembly, and more particularly, to a container assembly having a container and a cover cap provided with a pump member for discharging air from the container.

Generally, conventional vacuum container assemblies include a container that defines a storage space and has an upper open end for access to the storage space and an upper opening defined by the upper open end. The cover cap is mounted to the upper open end of the container to close the upper opening. A separate pump member is used to withdraw air from the storage space to preserve the food stored in the container.

In a conventional vacuum vessel assembly, the pump member is usually stored separately when not in use, so it is unknown where it is placed after use. In addition, conventional vacuum vessel assemblies require the user to use both hands to exhaust air from the vessel.

It is a primary object of the present invention to provide a container assembly having a container and a cover cap provided with a pump member to evacuate air from the container and avoiding the above drawbacks encountered during the use of conventional container assemblies.

Thus, the container assembly of the present invention includes a hollow casing, cover cap, pump member, pressurizing member, first check valve, second check valve and air-inlet valve. The container defines a storage space and has an upper opening end and an upper opening defined by the upper opening end for access into the storage space. The cover cap is detachably sealed to the top open end of the container to cover the top opening. The cover cap includes a pump mounting wall portion having a “U” shaped cross section defining a pump receiving chamber, an inlet formed at the pump mounting wall portion in fluid communication with the pump receiving chamber and a pump mounting wall portion. It extends outwardly and has a valve-mounted wall portion formed with an opening in fluid communication with the storage space. The pump member is movably sealed within the pump receiving chamber and can move toward and away from the inlet to change the pressure in the pump-receiving chamber by a change in the volume of the pump-receiving chamber. The pump member has an outlet for fluid communication between the pump-receiving chamber and the atmosphere. The pressing member pushes the pump member out of the inlet. A first check valve for closing the inlet of the pump-receiving chamber is mounted on the cover cap. The inlet can be opened when the pressure in the storage space is greater than the pressure in the pump-receiving chamber, thereby allowing fluid to enter the pump-receiving chamber from the storage space. The inlet can be closed by the first check valve when the pump member moves toward the inlet by the pressurizing action of the pressure member so that the pressure in the pump-receiving chamber is greater than the pressure in the storage space. A second check valve for closing the outlet of the pump-receiving chamber is mounted on the pump member. When the pump member moves toward the inlet by the pressure action of the pressure member, when the pressure in the pump-receiving chamber is greater than atmospheric pressure, the outlet can be opened, thereby allowing fluid to enter the atmosphere from the pump-receiving chamber. do. In the case where the pump member moves away from the inlet by the pressurizing action of the pressure member so that the pressure in the pump-receiving chamber becomes lower than the pressure in the atmospheric pressure and the storage space, the outlet can be closed by the second check valve and the inlet can be opened. . An air inlet valve for closing the opening of the cover cap is mounted on the valve mounting wall portion. The air-inlet valve is manually operable to open the opening in the cover cap when desired.
