Slanted sleeve 58 facilitates insertion and retention of nozzle 60. A bore 66 is formed for the purpose. The end of the pore 66 distal to the diffuser 62 is a widening point. It has a bore 67 and a wider bore 68. The thread 70 is larger than the diameter of the pore 68. It has a slightly smaller outer diameter and essentially "zero gap" with respect to pore 67. be. For example, enlarged bore 67 is approximately 12.5 μm larger in diameter than the outer diameter of the thread.

For use with pouches with a thin skin thickness of approximately 76 μm, the bore 68 has an outer diameter of the thread 70. The diameter is approximately 76 to 100 μm wider than that of the Thread 70 has a crimped end 72 .

In operation, nozzle 60 initially has at least threads 70 within bore 68. It's like being pulled in. The helical tip 69 is retrieved into the bore 67 so that the penetrating The entry tip 71 catches the pouch by chance and does not penetrate it. after that , the lid 35 captures the pouch ears 55 and 56 in the top rim 34 and 57 is closed in such a way as to hold it tight. The nozzle 60 of the discharge port 42 is The penetrating tip 71 is twisted so as to penetrate the thin skin 76 in the tension portion 57, Pushed. The helical tip 69 thus punctures the skin 76. spiral tip The end 69 has a thin skin 76 attached to a tapered portion 77 of the nozzle 60, as shown in FIG. The pouch 52 is gradually actuated by twisting until it is properly abutted. after that , the handle 63 of the tilting lever 59 is twisted until the detents 64 and 65 are engaged. It will be done. The thrust at sliding surfaces 78 and 79 (shown in FIG. 4) The helical tip 69 is then pulled away from the pouch 42. As shown in Figures 7 and 8. As shown, the helical tip 69 is pulled towards the bore 68 and the skin 76 is It is captured between threads 70 and 75 and bore 68. Now with thin skin coated threads Portions 70 and 75 have threads further displaced by a shoulder between bore 68 and narrow pore 67. It is forced into the bore 68 until it is prevented from moving. Then, the materials A mechanical system is formed by sandwiching a thin skin 76 between the threads 70 and 75 and the bore 68. leakage from the pouch 42 due to the contraction of the thin skin edge to the tapered portion 77. be prevented from being exposed. The tightening thread 72 extends along the entire length of the threaded portion. , if high pressure is applied by the piston disk 47, it will flow very much like water. Although not completely satisfactory in the case of liquids (through troughs in the threads) to help prevent material from being forced out of the pouch through the seal area. One. However, in such a case a different arrangement would be chosen. Material inside pouch 42 The material is removed by forcing the material through the bore of the nozzle 60. 9th In the case of the serrated end shown in the figure, the relative lengths of bores 67 and 68 are Determined by the length of the teeth. Numbers in Figure 9 indicate serrated ends. 6-8, except that the section is identified by the numeral 73.

Before the sawtooth portion 74 of the sawtooth portion 73 penetrates the pouch, the sawtooth Portion 73 is retracted into bore 67 so that teeth 74 can accidentally remove the pouch when not needed. It doesn't penetrate until it catches hold.
