Patent ID: 7540127

Claim:
A vacuum sealer, comprising: a lower body; an upper body pivotably mounted to the lower body in such a way as to engage with the lower body; a heater installed in either or both the lower body or/and the upper body, and heating and sealing a vacuum bag; a vacuum space creating member installed in either or both the lower body or/ and the upper body, and isolating an end of the vacuum bag which is evacuated from an exterior, thus creating a vacuum space; a vacuum pump coupled via a tube to an exhaust hole communicating with the vacuum space created by the vacuum space creating member; a holding part formed in the lower body, the holding part having: a first supporting part provided on one side and a first detaching part provided on another side, and a detachable member comprising a corresponding supporting part coupled to the first supporting part provided on the holding part of the lower body, and a corresponding detaching part coupled to the first detaching part provided on the holding part, wherein the vacuum space creating member is provided in the detachable member; wherein the corresponding supporting part and the corresponding detaching part of the detachable member comprise coupling parts having elasticity, locking steps coupled to the coupling parts and catch parts coupled to the locking steps; wherein the first supporting part and the first detaching part of the holding part of the lower body each comprise: respective gate parts which allow the respective locking steps of the corresponding supporting part and corresponding detaching part to be moved upwards and to be removed through upper openings of the gate parts, the upper openings having areas larger than the respective gate parts; respective locking parts which permit the passage of only the respective catch parts while preventing the upward movement of the respective locking steps of the corresponding supporting part and the corresponding detaching part by the upper openings of the locking parts having areas smaller than the respective locking steps; wherein the gate part of the first detaching part is longer than the gate part of the first supporting part, and the locking part of the first detaching part is shorter than the locking part of the supporting part; wherein the first supporting part and the corresponding supporting part are configured to couple to each other in a male-female coupling arrangement when the detachable member is installed in the holding part; and wherein the gate part of the first detaching part contacts the coupling part when the detachable member is attached to the holding part, and the locking step of the corresponding detaching part is configured for movement between the locking part of the first detaching part and the gate of part of the first detaching part, and is sized small enough to pass through the gate part when the detachable member is detached from the holding part.
