Blowing device for balloon

Abstract

A blowing device for inflating a balloon has a hollow body having a first end and a second end and including an internal air passage through these ends. The first end is connectable with the mouth of a balloon for air to be blown into the balloon from the second end via the air passage. An air valve in the air passage is operable to block passage of air escaping from inside the balloon in a direction from the first end to the second end. Also included are a light effect generator operated by a battery, and an operating member for turning on and off the light effect generator.

1 . A blowing device for inflating a balloon, comprising:
 a hollow body having a first end and a second end and including an internal air passage through the first and second ends, the first end being connectable with a mouth of a balloon for permitting air to be blown into the balloon from the second end via the air passage;   an air valve in the air passage, the air valve being operable to block passage of air escaping from inside the balloon in a direction from the first end to the second end;   an effect generator provided at the body, the effect generator being operated by a battery; and   operating means provided at the body for turning on and off the effect generator.   
     
     
         2 . The blowing device as claimed in  claim 1 , wherein the effect generator comprises at least one of a light generator and a sound generator. 
     
     
         3 . The blowing device as claimed in  claim 1 , wherein the air valve includes a valve member arranged to be acted upon by air inside the balloon to close the air valve. 
     
     
         4 . The blowing device as claimed in  claim 3 , wherein the valve member extends across the air passage and faces the interior of the balloon for action by air inside the balloon. 
     
     
         5 . The blowing device as claimed in  claim 3 , wherein the valve member is provided at the first end of the body. 
     
     
         6 . The blowing device as claimed in  claim 2 , wherein
 the effect generator comprises a light generator which includes a light source located at or adjacent the first end of the body, and   the air valve includes a valve member extending across the first end of the body for being acted upon by air inside the balloon to close the air valve, with the light source provided behind the valve member.   
     
     
         7 . The blowing device as claimed in  claim 3 , wherein the air valve includes a valve seat provided by a part of the body. 
     
     
         8 . The blowing device as claimed in  claim 7 , wherein the valve seat has a flat-cylindrical shape and extends radially outwardly of the body for receiving the valve member. 
     
     
         9 . The blowing device as claimed in  claim 8 , wherein the valve seat comprises a flange around the first end of the body, which flange presents a right-angled step for engaging the mouth of the balloon. 
     
     
         10 . The blowing device as claimed in  claim 3 , wherein the effect generator is provided at the valve member. 
     
     
         11 . The blowing device as claimed in  claim 3 , wherein the effect generator comprises a light generator which includes a light source located at or adjacent the first end of the body, and the light source is provided at the valve member. 
     
     
         12 . The blowing device as claimed in  claim 1 , wherein the operating means includes an operating member supported for movement in the body to a closed position, resulting in closing of a power circuit of the effect generator. 
     
     
         13 . The blowing device as claimed in  claim 12 , wherein the operating member is arranged to move with a valve member of the air valve. 
     
     
         14 . The blowing device as claimed in  claim 13 , wherein the operating member is connected with the valve member for simultaneous movement. 
     
     
         15 . The blowing device as claimed in  claim 13 , wherein the operating member is arranged to move in a first direction to turn on the effect generator and to move in a second direction, opposite the first direction, to move the valve member to an open position of the air valve. 
     
     
         16 . The blowing device as claimed in  claim 12 , wherein the operating means includes an operating part arranged to move the operating member in a first direction to the closed position and in a second direction, opposite the first direction, off the closed position. 
     
     
         17 . The blowing device as claimed in  claim 1 , wherein
 the air valve is, in use, normally-closed to block passage of air escaping from inside the balloon, and   the air valve comprises a valve seat and a valve member which is arranged to engage the valve seat, thereby closing the air valve, under the action of pressurized air inside the balloon.   
     
     
         18 . The blowing device as claimed in  claim 17 , wherein the air valve is provided at the first end of the body and is operated by means of an operating member extending from the valve member to the second end of the body, the operating member being movable by a force applied at the second end to open the air valve. 
     
     
         19 . The blowing device as claimed in  claim 1 , wherein the air valve and the effect generator turn on and turn off, in a complementary manner. 
     
     
         20 . The blowing device as claimed in  claim 1 , wherein the body comprises a cylindrical tube having a central axis along which the air valve and the effect generator are provided in a co-axial arrangement.
