as required , detailed embodiments of the present invention are disclosed herein ; however , it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms . the figures are not necessarily to scale ; some features may be exaggerated or minimized to show details of particular components . therefore , specific structural and functional details disclosed herein are not to be interpreted as limiting , but merely as a representative basis for teaching one skilled in the art to variously employ the present invention . referring now to fig1 , the invention has a case 10 that contains a case barrel 12 that is used to wrap the balloon around and a case handle 14 which the user holds . the case 10 has a case opening 18 that allows the internal mechanism hook and trigger assembly 24 to retract and extend . the internal mechanism hook and trigger assembly 24 has a friendly shaped trigger 26 which the user can actuate the assembly and an internal mechanism hook slot 28 which the end of the balloon can be inserted . referring now to fig2 , the internal mechanism hook and trigger assembly 24 which includes the internal mechanism trigger 26 and the internal mechanism hook slot 28 is shown on the retracted position indicated by the direction of the arrow . fig3 shows a center line section from fig1 along the axis 3 - 3 . the case 10 includes the case barrel 12 , a handle 14 , the case trigger slot 16 , and the case opening 18 . the case trigger slot 16 allows the internal mechanism trigger 26 to slide back and forth . the end of case 10 has a case opening stop ring 20 that prevent the internal mechanism hook and trigger assembly 24 from sliding out of the case 10 . this is due to the internal mechanism stop ring 30 being located on the internal mechanism hook and trigger assembly 24 by being larger than the case opening 18 . inside case 10 includes a case spring press surface 22 that allows a friendly surface area for the spring 32 to compress against . the spring 32 is located between the internal mechanism spring press surface 42 located on the internal mechanism hook and trigger assembly 24 and the case spring press surface 22 which is included within the case 10 . the internal mechanism hook and trigger assembly 24 has an internal mechanism spring press surface 42 that will compress the spring 32 against the case spring press surface 22 as the internal mechanism trigger 26 is pulled . referring now to fig4 , this section shows a center line section from fig2 along the axis 4 - 4 . the internal mechanism hook and trigger assembly 24 which includes the internal mechanism trigger 26 and the internal mechanism hook slot 28 is shown on the retracted position indicated by the direction of the arrow . by pulling on the internal mechanism trigger 26 , the internal mechanism spring press surface 42 pushes against the spring 32 compressing it against the case spring press surface 22 . when the internal mechanism trigger 26 is released by the user , the spring 32 will expand back to its resting position as shown in fig3 . referring now to fig5 , the invention is showing an example of the potential construction and components in an exploded view . the two halves of case 10 would contain the internal mechanism hook and trigger assembly 24 and the spring 32 . the two halves of case 10 could be secured using snaps , separate fasteners , or a combination of both . fig6 through fig1 shows an example of the process used to tie a knot in a balloon using this invention . referring now to fig6 , the user will hold a balloon against the case barrel 12 which is included in case 10 putting pressure against the balloon as indicated . the user will grip the exemplary balloon neck 38 of exemplary balloon 34 and pull in the direction indicated by the arrow . referring now to fig7 , the user continues to pull on the exemplary balloon neck 38 wrapping it around the case barrel 12 and then under the exemplary balloon 34 . meanwhile , the user is still applying pressure to the exemplary balloon 34 as indicated . referring now to fig8 , the user will tuck the exemplary balloon opening 36 or the end of the balloon into the internal mechanism hook slot 28 which is included in the internal mechanism hook and trigger assembly 24 . referring now to fig9 , the internal mechanism hook and trigger assembly 24 is actuated by the user pulling the internal mechanism trigger 26 . this will retract the internal mechanism hook slot 28 indicated by the direction of the arrows . this action will pull the exemplary balloon opening 36 and exemplary balloon neck 38 tucked into the internal mechanism hook slot 28 into the case barrel 12 which created the wrapped balloon loop . not shown is the spring 32 inside the case 10 is now in a compressed state . referring now to fig1 , the exemplary balloon 34 is slid off the case barrel 12 . the exemplary balloon opening 36 and exemplary balloon neck 38 are still secured by the actuated internal mechanism hook slot 28 which is included in the internal mechanism hook and trigger assembly 24 . referring now to fig1 , the exemplary balloon 34 is pulled tight for form a knot 40 . the exemplary balloon opening 36 and exemplary balloon neck 38 are still secured by the actuated internal mechanism hook slot 28 which is included in the internal mechanism hook and trigger assembly 24 . referring now to fig1 , the user releases the internal mechanism trigger 26 which is included in the internal mechanism hook and trigger assembly 24 . the spring 32 , not shown , will push the internal mechanism hook and trigger assembly 24 back to its original position within case 10 as indicated by the direction of the arrows . referring now to fig1 , the exemplary balloon neck 38 is removed from the internal mechanism hook slot 28 which includes the balloon knot 40 . fig1 shows the final exemplary balloon 34 including the knot 40 tied in the balloon neck 38 which prevents air or water , in the case of water balloons , from exiting the exemplary balloon opening 36 .
an assembly having a mechanical process which allows a user to tie a knot in a balloon . a hook feature in the assembly will hold the end of the balloon . the neck of the balloon is wrapped around the assembly creating a loop . the hook feature is actuated by a spring loaded trigger that will pull the end of the balloon through the balloon loop which will create a knot .
