Abstract
An inflatable toy includes a pump bladder having two one-way valves. One is used for inflation, and the other is used for deflation. A deformable bladder is connected to the pump bladder and located at a position close to the one-way valve used for deflation. The deformable bladder has another one-way valve used for deflation. The deformable bladder can be inflated by pressing the pump bladder repeatedly. The inflatable toy is a novel toy, allowing children to change the size of the inflatable toy as desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0022] Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
[0023] Referring to FIG. 1, FIG. 2 and FIG. 3, the present invention discloses an inflatable toy, comprising a plurality of one-way valves 1. The one-way valve 1 includes a housing 11, a plug 12, and a stopper 13. The housing 11 has an open room 111 therein, an opening 112 in the center of the bottom of the room 111, and a pair of perforations 113 on two corresponding sides thereof. The plug 12 is disposed in the room 111. The plug 12 includes a post portion 121 and a truncated cone portion 122 connected to one end of the post portion 121. The post portion 121 passes through the opening 112 and partially extends out of the opening 112. The post portion 121 is movable in the opening 112. The stopper 13 is connected between the two perforations 113. As shown in FIG. 3, when the pressure at the end close to the stopper 13 is greater than the pressure at the other end close to the opening 112, the plug 12 is moved in a direction facing the opening 112 to close the opening 112; conversely, when the pressure at the end close to the stopper 13 is less than the pressure at other end close to the opening 112, the plug 12 is moved in a direction facing away from the opening 112 to open the opening 112.
[0024] Referring to FIG. 4, the toy 2 includes a deformable bladder 21 and a pump bladder 22 located inside the deformable bladder 21. The deformable bladder 21 has a deformation space 211 therein. The pump bladder 22 has a pump space 221 therein. A first opening 222 is formed at one end of the pump bladder 22. A one-way valve 1 is provided at the first opening 222 for inflation, and its post portion 121 is oriented towards the outside of the toy 2. A second opening 223 is formed at the other end of the pump bladder 22. Another one-way valve 1 is provided at the second opening 223 for deflation, and its post portion 121 is oriented towards the pump space 221 of the toy 2. The outer edge of the second opening 223 communicates with the deformation space 211. The deformable bladder 21 has an accommodating portion 23 at any position thereof. A further one-way valve 1 is provided at the accommodating portion 23 for deflation, and its post portion 121 is oriented towards the outside of the toy 2.
[0025] The pump bladder 22 may be disposed inside the deformable bladder 21, but it may be not located inside the deformable bladder 21. The pump bladder 22 and the deformable bladder 21 may be two individual bladders connected to each other. The pump bladder 22 is preferably made of a material that is deformable, has low ductility and can be automatically restored to the original shape. The deformable bladder 21 is preferably made of a TPR material (Thermo-Plastic-Rubber material) with high ductility and elasticity.
[0026] Referring to FIG. 4, the toy 2 is not in an inflated state. The user's fingers 9 press the pump bladder 22 repeatedly via the deformable bladder 21. Referring to FIG. 5, when the pump bladder 22 is pressed, the air in the pump space 221 is discharged toward the deformation space 211 via the one-way valve 1 at the second opening 223 to enlarge the deformation space 211, in cooperation with the one-way check function of the one-way valve 1 of the accommodating portion 23. When the fingers 9 release the force on the pump bladder 22, the pump bladder 22 will automatically expand to be restored to its original shape. Referring to FIG. 6, when the pump bladder 22 is restored, the internal negative pressure will cause the one-way valve 1 at the first opening 222 to open and inflate the pump bladder 22, so that the pump bladder 22 is inflated again. The deformable bladder 21 can be gradually enlarged by repeating the above actions.
[0027] Referring to FIG. 7, when the inflated toy 2 is to be deflated, the post portion 121 of the one-way valve 1 located at the accommodating portion 23 is pressed to open the one-way valve 1, so that the air in the deformation space 211 is discharged to reduce the size of the toy 2. It is easy to operate the toy for young children.
[0028] FIG. 8 and FIG. 9 illustrate another embodiment of the present invention. The pump bladder 22 is connected to the deformable bladder 21. Basically, the principle of action is the same as the foregoing embodiment.
