Description
- (a) Technical Field of the Invention
- The present invention generally relates to vacuum containers, and more particularly to a nozzle device for the vacuum containers.
- (b) Description of the Prior Art
- Taiwan Patent Application No. 85215045 discloses an improved structure for a vacuum bag. The vacuum bag contains a bag member which is open at one side but sealed at all other sides. The bag member has a through hole at an appropriate location on the surface of the bag member. A clip member is configured close to the open side for closing the open side air-tightly. The through hole is configured with a nozzle device. The nozzle device has a bottom seat with a circular tubular section extended out through the through hole. The outside surface of the tubular section is threaded so that a top cover having a center hole matching the tubular section could be screwed tightly on the bottom seat. The top cover is connected with a cap for closing the tubular section of the bottom seat. Within the tubular section, the bottom seat has at least a through air hole so that air in the bag member could be vacuumed out through the air hole. A circular film element is positioned inside the tubular section. The film element has a circular ring with a flexible circular film in the center, leaving at least an opening between the circular ring and the film. The film is right on top of the air hole.
- Taiwan Patent Application No. 81217008 discloses a vacuum container for preserving food freshness. The vacuum container has a cylindrical body member and a cover member for closing the body member into an airtight space. In the center of the cover member, there is a circular concave on the top surface. At the bottom of the circular concave, there is at least an air hole so that air in the body member could be pumped out. A circular film element is positioned inside the circular concave. The circular film element has a circular ring with a flexible film in the center. When a user places a pump in the circular concave and starts pumping, the pressure would lift the rim of the flexible film upward so that air in the body member could be vacuumed out. As the body member is vacuumed, another thin film is placed inside the circular concave and the atmospheric pressure pushes the circular film and thin film to close the air hole tightly and keep the body member vacuumed.
- Taiwan Patent Application No. 9221096 discloses a vacuum bag having a nozzle device. A bottom seat of the nozzle device is configured inside the vacuum bag and has a joining section extending out of a through hole of the vacuum bag. In the center of the joining section, there is an air duct whose bottom has a number of air holes. The nozzle device also contains a plug element whose one end is a plug for the air duct, and whose the other end is a flexible piece for covering up the air duct. The flexible piece has a number of air holes near and surrounding the plug. When the bag is vacuumed, the plug element's flexible piece is sucked up to allow air from the bag to pass through the air duct and the air holes. After the bag is vacuumed, a cover member forces the flexible piece plug element to extend and close tightly on the air duct.
- From the foregoing description, the nozzle devices disclosed in prior arts are complicated both in terms of structure and assembly. This is not only inconvenient to use, but also costly to manufacture.
- The primary purpose of the present invention is to provide a nozzle device for a vacuum container. The nozzle device has a molded and flexible seat member with a cover member attached. The center of the cover member has a convex section which will become a concave one when the container is vacuumed. As such, a user could easily tell whether the container is vacuumed or not.
- Additionally, as pointed objects are usually put inside a plastic bag first before being stored inside the container so that the container would not be punctured. However it is often found that the air in the plastic bag couldn't be vacuumed. The present invention provides a ventilated inner layer inside the container so that pointed objects could be placed directly inside the container without using a separate plastic bag and the container could be vacuumed completely.
- The seat member of the nozzle device is a planar disc with a protruding tubular section in the center. The cover member is attached to the top rim of the tubular section. Inside the tubular section, there is an air duct whose top end has a slot opening on the end surface with two slope surfaces at the two sides of the slot opening. The air inside the container is vacuumed through the slot opening and, when the vacuuming stops, the atmospheric pressure would force the slot opening to close. Accordingly, the present invention achieves convenient vacuuming using only a very simple structure.
- The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.
