Abstract: A one-way air outlet channel is disposed inside a vacuum compression bag. The one-way air outlet channel includes an air inlet opening, a horizontal air channel, inclined air channel and vertical air channel and an air outlet opening in communication with one another in sequence. One end of the horizontal air channel is the air inlet opening in communication with a space inside the bag body, and the other end of the horizontal air channel is in communication with the inclined air channel. A bottom end of the vertical air channel is in communication with the air outlet opening, and a top end is in communication with the inclined air channel, such that at least two corner points are formed, at a location where the horizontal air channel connects the inclined air channel and at a location where the inclined air channel connects the vertical air channel.

Abstract: A suction cup, including a flat framework, a suction cup body covering the framework, a connection rod disposed on the back surface of the framework and passing through the cup body, a cup cover covering the connection rod and the cup body, and a pressing element provided on the back surface of the cup cover and in connection with the connection rod, a seal element on the adsorption surface of the cup body, and an annular protruding ring on the inner surface of the cup cover at a location corresponding to the seal element for touch pressing the inner surface of the cup body against the seal element. The invention uses rigid force transfer, and thus the force transfer is more effective. The sealing element enhances the airtightness of the suction cavity and increases the absorption force of the suction cup.

Abstract: A suction cup, including a bowl-shaped framework, a cup body covering the framework, a connecting rod on a back surface of the framework and passing through the cup body, a bowl-shaped cup cover placed on the connection rod and covering the back surface of the cup body, and an annular protruding rib placed on the periphery of the back surface of the framework, which is in direct contact with the inner surface of the cup cover for effectively transfer the pressing force to make the suction cup less likely to fall off from the supporting surface.

Abstract: This invention provides a vacuum bag, including vacuum bag (1), gas nozzle (13) on the bag (1) which can exhaust air out, inlet (11) in the upper part of vacuum bag through which items can be placed into the bag, and sealing device (12) which can seal the inlet. The invention is characterized in its outer packing part (2) which can incorporate up the bag, and tightening device (3) between the vacuum bag and outer packing part. This invention overcomes the shortage of current craft and provides a vacuum bag with reasonable structure, that is easy to use and can be stacked neatly and prevents from damage.

Abstract: A vacuum packing bag having a bag body (3), a reopenable seal and a vacuum valve (4) provided on the bag body. The bag body is formed by at least one front bag piece (1) and one back bag piece (2), and a fork-like opening (8) is formed at the top of the joint between the front bag piece and the back bag piece. A cover piece (5) is connected with the fork-like opening and has connection edges (52) and at least one movable edge (51). The connection edges are joined with corresponding edges of the front bag piece and the back bag piece at the fork-like opening, and the movable edge is joined with the upper edge of the front bag piece at the fork-like opening to form an opening (6) of the packing bag and constitute a movable seal. The vacuum packing bag has a simple design, an opening that can be sealed more quickly and conveniently for a labor-saving operation.
