BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an aerating bag, and more particularly relates to an aerating bag that can improve the air inflation efficiency of the aerating bag.

2. Description of Related Art

With reference to FIGS. 8 and 9A, a conventional aerating bag is used to inflate objects such as insoles of an air cushion shoe, pad protective covers, bike inflatable cushions or sports protectors, and has an inflatable segment 70, a vent segment 80 and a unidirectional gas nozzle 90. The inflatable segment 70 is made of an elastic material such as rubber to store air, is extrudable and has an upper membrane 71, a lower membrane 72 and a concaved segment 73. The upper membrane 71 has a front end, a rear end and a bottom. The lower membrane 72 is connected to the upper membrane 71 to form the closed inflatable 70 and has a top side and a bottom side. The top side of the lower membrane 72 is connected to the bottom of the upper membrane 71. The concaved segment 73 is formed in the upper membrane 71 between the front end and the rear end of the upper membrane 71, faces the top side of the lower membrane 72 to form a gap between the upper membrane 71 and the lower membrane 72. In addition, the concave segment 73 has a middle.

The vent segment 80 is formed on the front end of the upper membrane 71 of the inflatable segment 70, selectively communicates with the inflatable segment 70 and has an outlet 81. The outlet 81 is connected to the bottom side of the lower membrane 72 near the front end of the upper membrane 71. The unidirectional gas nozzle 90 is securely mounted in the gap between the concaved segment 73 and the lower membrane 72 at the middle of the concave segment 73 to enable the vent segment 80 to communicate with the inflatable segment 70 and has two valve slices 91, 92. The valve slices 91, 92 are included an upper valve slice 91 and a lower valve slice 92. The lower valve slice 91 is mounted between and abuts the upper valve slice 91 and the top side of the lower membrane 72. Each one of the valve slices 91, 92 has a shape, an outer periphery, a front end and a rear end. The shapes of the valve slices 91, 92 are the same, the front ends of the valve slices 91, 92 extend into the vent segment 80 and the rear ends of the valve slices 91, 92 extend into the inflatable segment 70. Furthermore, the valve slices 91, 92 are overlapped with each other at the middle of the concave segment 73 to enable the outer periphery of the upper valve slice 91 to align with the outer periphery of the lower valve slice 92.

In use, with reference to FIGS. 9A and 9B, the membranes 71, 72 of the inflatable segment 70 are respectively pressed by two fingers of a user to extrude the inflatable segment 70 to enable air that is stored in the inflatable segment 70 to flow into the vent segment 80 via the unidirectional gas nozzle 90. However, when the inflatable segment 70 is extruded by the user's fingers, the rear ends of the valve slices 91, 92 may be pressed with the deformation of the membranes 71, 72. Then, the rear ends of the valve slices 91, 92 cannot be open to enable air to flow into the vent segment 80, and this means the rear ends of the valve slices 91, 92 cannot be open to form an interval to enable air to flow into the vent segment 80 because the deformation of the membranes 71, 72 of the inflatable segment 70. Therefore, air that is stored in the inflatable segment 70 cannot be successfully flowed into the vent segment 80 when the user presses and extrudes the inflatable segment 70, and this means the user needs to press and extrude the inflatable segment 70 of the conventional aerating bag many times to achieve an air inflation effect and this will significantly reduce the air inflation efficiency of the conventional aerating bag.

Therefore, the present invention provides an aerating bag to mitigate or obviate the aforementioned problems.

The spring 22 is mounted around the rod 213 of the control valve 21 and is pressed against the pressing tab 211 and the separating board 173 to enable the holding head 215 to press against the bottom of the controlling device 20 to prevent the through hole of the separating board 173 from communicating with the outlet chamber 175. The cover 23 is made of plastic and is formed on and protrudes from the external surface of the controlling device 20 near the top of the controlling device 20 to mount in the top of the controlling device 20 to close the control valve 21.

The unidirectional gas nozzle 30 is mounted in ventilating duct 15 of the body 10 between the inflatable chamber 16 and the outlet chamber 175 of the vent segment 17 and has two valve slices 31, 32 mounted between the middle and one of the curved ends 141, 142 of the concaved segment 14. The valve slices 31, 32 include an upper valve slice 31 and a lower valve slice 32, and each one of the valve slices 31, 32 has a shape, an outer periphery, a front end and a rear end. The shapes of the valve slices 31, 32 are the same. The front ends of the valve slices 31, 32 may be rectangular and extend into the outlet chamber 175 of the vent segment 17. In addition, the front end of one of the valve slices 31, 32 is mounted over the communicating hole 121 of the lower membrane 12. The rear ends of the valve slices 31, 32 may be triangular and extend into the ventilating duct 15. Furthermore, the valve slices 31, 32 are overlapped with each other in a misalignment state to enable the front end, the rear end and the outer periphery of one of the valve slices 31, 32 to misalign with the front end, the rear end and the outer periphery of one of the other one valve slice 31, 32. In the first embodiment of the aerating bag in accordance with the present invention, the valve slices 31, 32 are mounted between the middle and the first curved end 141 of the concaved segment 14.

The connecting end of the outlet 40 is connected to the communicating hole 121 of the lower membrane 12. The inserting end of the outlet 40 is formed with the connecting end of the outlet 40.

With reference to FIG. 7, a second embodiment of an aerating bag in accordance with the present invention has similar structures substantially the same as the structures in the above-mentioned first embodiment of the aerating bag except the following features. The valve slices 31, 32 of the unidirectional gas nozzle 30′ are mounted between the middle and the second curved end 142 of the concaved segment 14.

With reference to FIGS. 4 and 5, when using the aerating bag in accordance with the present invention to fill air into an object, putting the inserting end of the outlet 40 into the object and pressing the membranes 11, 12 of the body 10 to let the air in the inflatable chamber 16 to flow into the ventilating duct 15. At the same time, the air will also enable the sealing slice 133 to close the inlet channel of the holding mount 131 to prevent the air from flowing out of the inflatable chamber 16 via the holding mount 131.

Because the valve slices 31, 32 are overlapped with each other in a misalignment state and are mounted between the middle and one of the curved ends 141 of the concaved segment 14. When the membranes 11, 12 of the body 10 is extruded by the user's fingers, the deformation of the membranes 11, 12 at the middle of the concaved segment 14 will not interfere the movement of the valve slices 31, 32. Then, the air can easily and successfully enable the air to separate the rear ends of the valve slices 31, 32 to allow the air passing through the front ends of the valve slices 31, 32. Then, the air can flow into the object via the outlet chamber 175, the communicating hole 121 of the lower membrane 12 and the outlet 40. Furthermore, after the user's fingers pressing the membranes 11, 12, the inflatable chamber 16 is set in the vacuum state and this can make the sealing slice 133 to move upwardly relative to the holding mount to allow the outside air to flow into the inflatable chamber 16 via the inlet channel and the mounting recess 135 when the user removes the fingers from the membranes 11, 12. After the above-mentioned operating cycle, the object can be inflated completely.

With reference to FIG. 6, when the object is needed to release, the user can open the cover 23 and press the pressing tab 211 of the control valve 21 downwardly to enable the holding head 215 to separate from the bottom of the separating board 173. Then, the air in the object can be flowed out of the object via the outlet 40, the outlet chamber 175, the through hole of the separating board 173 and the open top of the vent mount 171.

According to the above-mentioned features and structural relationships of the aerating bag in accordance with the present invention, first, the valve slices 31, 32 are overlapped with each other in a misalignment state to enable the front end, the rear end and the outer periphery of one of the valve slices 31, 32 to misalign with the front end, the rear end and the outer periphery of one of the other one valve slice 31, 32. Second, the valve slices 31, 32 are mounted between the middle and one of the curved ends 141, 142 of the concaved segment 14 to prevent the valve slices 31, 32 interfering from the deformation of the membranes 11, 12 at the middle of the concaved segment 14 of the body 10. Then, the air in the inflatable chamber 16 can easily and successfully enable the air to separate the rear ends of the valve slices 31, 32 to allow the air passing through the front ends of the valve slices 31, 32 and flow into an object, and this can significantly improve the air inflation efficiency of the aerating bag.
