Description

  The present invention relates to a medicine barrel for a vapor pressure crushing agent.

  Conventionally, in a steam pressure crushing in which water vapor is generated in a short time by heat generated in a medicine and the rock or concrete is crushed by the pressure of the water vapor, a medicine cylinder for containing the medicine has been proposed (for example, Patent Document 1). reference).

  FIG. 8 is a cross-sectional view of a medicine cylinder described in Patent Document 1. As shown in FIG. 8, the medicine cylinder 100 includes a resin medicine cartridge body 101, and one end side of the medicine cylinder body 101 is shown. An igniter support protrusion 103 made of a conductive material is inserted into the through hole 102. The igniter support protrusion 103 is made of resin, and includes an insertion portion 105 that is inserted into the barrel main body 101 and a flange portion 106 that is fixed to one end of the barrel main body 101 by adhesion and welding. An igniter insertion hole 108 is formed in the center of the igniter support protrusion 103 so as to open toward the flange portion 106 and into which the igniter 107 is inserted. On the other hand, an opening 111 for filling a medicine is formed on the other end side of the medicine barrel main body 101. The opening 111 is closed with a resin cap 112 after the medicine cylinder body 101 is filled with the medicine, and thereby the sealed state of the medicine cylinder 100 is maintained.

  By the way, in recent years, there has been a demand for a medicine barrel having a simpler structure at a lower cost. However, in the case 100 of Patent Document 1, at least three parts including the case main body 101, the igniter support protrusion 103, and the cap 112 are required, and the number of parts and the number of processing steps increase. Further, since the collar portion 106 of the igniter support protrusion 103 is fixed to the barrel main body 101 by bonding and welding on one end side of the barrel main body 101, the sealing property of the fixing portion by the bonding and welding is sufficiently sufficient in the subsequent process. It was necessary to inspect, and this inspection took time and cost. In addition, on the other end side of the medicine barrel body 101, an end portion of the medicine barrel body 101 formed by blow molding is cut to provide an opening 111, and after filling the medicine from the opening 111, the cut end portion is capped. In general, the opening 111 is closed by being reused as 112. In this case, since the cut end portion has low dimensional accuracy, sufficient fitting strength and sealability cannot be obtained simply by fitting the cut end portion (cap 112) into the opening 111. For this reason, it has been necessary to fix the cap 112 to the barrel body 101 by, for example, winding a tape or the like around the cap 112 and the barrel body 101 to improve the sealing performance.
