Claims34
A vacuum valve device for a bag having a sealing cavity formed between two sheets and a through hole formed at one of said sheets, comprising:
- a valve body having an air passage and defining a first opening and a second opening, wherein said valve body is adapted for being disposed within said sealing cavity at a position that said air passage is extended through said through hole of said sheet such that said first opening of said air passage is located out of said sealing cavity while said second opening of said air passage is located within said sealing cavity;
- a valve retainer detachably coupling with said valve body for securely sandwiching said sheet between said valve body and said valve retainer around said through hole in an air-tight manner;
- and
- a valve member disposed within said air passage between said first and second openings for enabling air within said sealing cavity being sucked thereout in only one direction so as to prevent said air being returning back to said sealing cavity.
A vacuum valve kit for a bag having a sealing cavity formed between two sheets and a through hole formed at one of said sheets, comprising:
- a vacuum valve device, which is a one-way valve, comprising a valve body, having an air passage, adapted for being disposed within said sealing cavity at a position that said air passage is extended through said through hole of said sheet, a valve retainer detachably coupling with said valve body for securely sandwiching said sheet between said valve body and said valve retainer around said through hole in an air-tight manner, and a valve member disposed within said air passage for enabling air within said sealing cavity being sucked thereout in only one direction so as to prevent said air being returning back to said sealing cavity;
- and
- a hole maker which comprises a circular cutting blade having a diameter corresponding to said valve body for making said through hole on said sheet so as to enable said air passage fittingly extending through said through hole.
