PURPOSE: To prevent the rotation and slipping-off of the accessories and to fix and fasten them without changing the structure of a container by providing a hooking device of accessories of a container with an inside sleeve, and forming this sleeve as snap rings beaten-in between helicoidal threads of the screw ring. CONSTITUTION: A container 1 has a screw ring 2 on its upper part, and the ring 2 is used for fixing the accessories composing a feed distributor 3. The feed distributor 3 has a sleeve 5, an array of parallel snap rings 6 is formed on an inner lower part of the sleeve, their cross sections are trapezoidal, and the number thereof is larger than the number of the helicoidal threads 7 of the screw ring 2. A skirt 10 extended inside the sleeve 5 is formed in order not to contact the product in the container 1 with the snap rings 6 and the threads of screw 7, and the skirt 10 is provided on an apex of the ring 2. When the snap rings 6 are beaten-in between helicoidal threads of screw 7 for fixing the feed distributor 3, the snap rings 6 are superimposed on these threads of screw and pushed therein. Whereby the rotation of the feed tool to the container can be prevented. |
