  • a pressure ball point pen of the above third embodiment may be prepared by an apparatus in accordance with the invention in such a way that an open end of the ink reservoir containing the writing ink and having a ball point means at its opposite end is inserted into a high pressure gas chamber of the apparatus and closed by a closing plug of heat fusible material having a vertical groove for air inlet and then compressed air is supplied into the high pressure gas chamber from the supply source and subsequently into the space formed between the ink and the closing plug through the air inlet groove provided in the plug and finally the ultrasonic oscillation is transmitted through an oscillator to the plug for thermal welding with the open end of the ink reservoir thereby to provide a compressed air chamber between the ink and the end closure plug.
  • Still a further object of the invention is to provide a method of manufacturing a pressure ball point pen which comprises filling an elongated ink reservoir having at its one end a ball point means with the writing ink, closing an opposite open end of said ink reservoir by an end closure member of heat fusible material, subjecting the end closure member to an ultrasonic oscillation for welding attachment with the open end of the ink reservoir thereby to provide a compressed air chamber between the ink surface and the end closure member.
  • Yet a further object of the invention is to provide an apparatus for manufacturing a pressure ball point pen which comprises a base body, an elastic holding mass member accomodated in the base body and provided with an aperture for supporting an open end portion of elongated ink reservoir and a high pressure gas chamber, an ultrasonic oscillation means disposed in the base body in alignment with the aperture for transmitting an ultrasonic oscillation to an end closure member inserted into the open end of the ink reservoir and a path disposed above the ultrasonic oscillation means and communicating into the high pressure gas chamber.
  • FIG. 1 is a vertical view partially in sectioned of the ball point pen in accordance with the invention
  • FIG. 2 is a pictorial elevation of an end closure memher before being inserted into an open end of the ink reservoir;

  • Outer circumferential surfaces of the sealing member 22 and the closing member 24 may be applied with grease or putty to minimize a friction with an inner circumferential wall of the ink reservoir on insertion and to prevent any leakage of the compressed air from the chamber 18.
  • the support arm 16 and the airtight seal member 22 may be fixed to the inner circumferential wall of the reservoir tube 10 by a suitable bond when desired.
  • a movable plug 30 having approximately 0.2mm smaller diameter than the inner diameter of the reservoir tube 10 and less specific gravity than the writing ink in the reservoir may be floated in the ink surface to check the counter flow of the ink.
  • an elongated inner ink reservoir 32 made of steel or other suitable synthetic material is provided with a ball point 34 at its one end and the opposite end thereof is left in open.
  • the inner ink reservoir tube 32 at its proper circumferential portion is somewhat depressed inwardly to form an annular channel 36 along which an elastic annular ring 38 is encircled as best shown in FIG. 3.
  • the elastic annular ring 38 is preferably made of rubber or synthetic resin.
  • the elongated inner ink reservoir 32 is filled with the writing ink leaving the upper portion in vacant to provide a pressure chamber 40 as hereinafter described.
  • the open end of the inner ink reservoir 32 is inserted into an outer sleeve 42 of somewhat larger diameter than the outer diameter of the reservoir and having a closed bottom end and when the annular ring 38 is forced into the outer sleeve 42, an air flow from the reservoir tube is completely confined and the pressure in the pressure chamber 40 is raised to approximately two atms by sliding the inner reservoir upwardly. It will be appreciated that the annular ring 38 should be properly positioned to keep the pressure in the pressure chamber 40 at approximately two atms.
  • an open end of the outer sleeve 42 is somewhat bent inwardly to make a fixed engagement with a shoulder portion 44 of the ink reservoir.
  • the open end of the outer sleeve 42 may be provided with a threaded portion or other suitable fixing elements so that the inner reservoir 32 after the ink therein worn out may be replaced by a fresh reservoir containing the ink.
  • FIG. 5 shows another embodiment of the ball point pen according to the invention, wherein an open end of the ink reservoir 46 is closed by an airtight plug 48 of heat fusible material such as vinyl chloride and the details of closing operation will be described hereinafter.
  • the airtight plug 48 comprises a head rim 50 integrated with a stem 52 and an extended leg 54 and provided with one or more vertical groove 55 which extends from the tip of the leg 54 to the position at least across the stem 52.
  • the open end of the ink reservoir tube 46 is interiorly provided with a stepped portion 56 adapted to receive the stem 52.
  • an apparatus for manufacturing the ball point pen illustrated in FIG. 5 is constructed of a base body 58 which accomodates an elastic support member 60 having an aperture 62 for supporting an open end portion of the ink reservoir tube 46.
  • the elastic member 60 is further provided with a recess 64 which provides a high pressure chamber 66 when the elastic member 60 is united with the base body 58.
  • the base body 58 further accomodates an ultrasonic oscillator 68 disposed in alignment with the aperture 62 and one end of the ultrasonic oscillator 68 is exposed into the high pressure gas chamber 66 in opposite relation with the head rim 50 of the air-tight plug 48.
  • a pressurized air path 70 communicating at its one end into the high pressure gas chamber 66 and communicated at its opposite end with a pipe 72 connected in turn to a solenoid valve 74 and a pressure gauge 76.
  • the open end of the ink reservoir tube containing the writing ink is mounted in the aperture of the elastic support member and then the airtight plug is inserted into the open end portion so that the head rim of the airtight plug confronts with the end of the oscillator.
  • the solenoid valve is opened to supply the dehydrated air or other suitable inert gas at a suitable pressure into the high pressure gas chamber.
  • the gas is further supplied into the space formed between the ink surface and the closing plug through the vertical groove provided in the closing plug.
  • the oscillator is moved toward the head rim of the plug for compression and simultaneously an oscillation is applied thereto to transmit the oscillation to the contacting portions between the plug and the open end of the ink reservoir so that the heat is generated therebetween with fusing of the plug member.
  • the fused material is penetrated into the vertical groove of the airtight plug resulting with an intimate fixation of the closing plug with the open end of the ink reservoir thereby to provide the compressed air chamber at the end portion of the ink reservoir.
  • a compressed air of desired pressure may be sealed into the ink reservoir in a simple and effective manner for the purposes of smooth and extended writing by the user without following any leakage of the ink.
