[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cartridge-type sealant extruding container that accommodates and seals a viscous sealant, and when the sealant of the outflow pipe is opened at the time of use, the sealant can be extruded from a nozzle of the outflow pipe by an extrusion gun to a desired location. In particular, the object is to improve the outflow pipe with a nozzle provided at the top of the container.

[0002]

[Prior art]

 The cartridge type sealant extruding container has a basic structure including a cylindrical body, a canopy with an outflow pipe provided at one end of the body, and a plunger slidably fitted in an opening at the other end of the body. With. Conventionally, in the above-mentioned container, it is disclosed, for example, in Japanese Utility Model Publication No. 3-27983 that the body, the canopy, and the outflow pipe of the male screw cylinder projecting to the center of the canopy are formed integrally with each other. A canopy in which an outflow nozzle is integrally formed with a synthetic resin is attached to one end of the above, for example, Japanese Patent Publication No. 2-60585 discloses a synthetic resin fitted with a paper cylinder barrel, a metal plate canopy, and the center of the canopy. A flanged male threaded cylinder made of an outflow pipe is conventionally known as disclosed in, for example, Japanese Utility Model Laid-Open No. 60-13337.

[Problems to be solved by the device]

 The conventional cartridge type sealant extruding container as described above, in which the outflow nozzle is fixed to the canopy part provided at one end of the body part, can be used immediately after cutting and releasing the tip of the nozzle. Depending on the conditions of the above, a separate container with an outflow nozzle having a different shape is required, and if the outflow pipe itself is a male screw cylinder, various nozzles should be selectively attached to suit the usage conditions. It has the advantage that

However, when using a container provided with an externally threaded tube type outflow pipe, it is necessary to screw the nozzle in place, and when replacing the screwed nozzle with another nozzle, each screw is unscrewed. The dressing operation had to be performed, which was insufficient in terms of streamlining the gap filling work. The present invention provides a container having an externally threaded outflow nozzle capable of performing efficient work, which has the advantages of the fixed outflow nozzle and the externally threaded tubular outflow pipe.

[0005]

[Means for Solving the Problems]

 The present invention is a thermoplastic synthetic resin in which a male-threaded cylindrical portion protruding outwardly located in the center of the canopy of a sealant extruding container and communicating with the inside of the container and a tapered cylindrical portion having a continuous tip sealed to this are integrated. The present invention is directed to a cartridge type sealant extruding container having an externally threaded outflow nozzle, characterized in that an outflow nozzle made of steel is provided. Therefore, the outflow nozzle can take various mounting modes as described below depending on the conditions of the container body and the canopy.

(A) The body of the container, the canopy, and the outflow nozzle projecting from the canopy are integrally formed of thermoplastic synthetic resin. (B) The body of the container is made into a paper cylinder, and the canopy and the outflow nozzle are fitted and fixed to the open end of the paper cylinder as an integral part of the thermoplastic synthetic resin. (C) The body of the container is a paper cylinder, and the canopy connected to the open end is made of metal plate or paper plate, and the outflow nozzle made of thermoplastic synthetic resin has a flange at the lower end of the male screw cylinder, and the center of the canopy. Fit and fix in the opening. As described above, the attachment conditions of the outflow nozzle are changed according to the type of container.

(B) When a paper cylinder is used as in (C), a lining similar to the inner seal of (a) is provided on the inner surface of the paper cylinder, and a paper board top plate is used as in (C). When a lid is used, it is necessary to provide an adhered layer similar to the lining on the inner surface side and a thermoplastic synthetic resin layer on the outer surface side to reinforce the paper board while providing gas-liquid barrier property. . If a canopy made of a metal plate is fitted on the open end of the paper cylinder, the canopy rim is clamped and fixed, and if it is a thermoplastic synthetic resin canopy, the rim of the canopy is heat-deformed or fixed. A paper tube is provided with a rising peripheral wall at the outer peripheral edge of the lid and the inner edge of the paper tube is curled to fix it, or a double tubular flange extending downward from the peripheral edge of the canopy is provided. When the canopy edge is fitted and fixed, and in the case of a canopy made of paper board, a rising edge is provided on the outer peripheral edge of the canopy, and the paper tube cylinder edge is curled inward so as to cover it, and then fixed. Appropriate bonding sealing means such as heating and heating to improve the sealing performance by fusing the thermoplastic synthetic resin is adopted.

Further, when the outflow nozzle having a flange at the lower end is fitted into the central opening of the metal plate canopy as in (C), the external diameter of the threaded portion of the male screw cylinder of the outflow nozzle is set to the center of the canopy. Provide a ring-shaped projecting locking ridge with an outer diameter slightly larger than the screw outer diameter on the non-threaded cylindrical portion that is the same as or slightly larger than the inner diameter of the opening and is below the male threaded portion, and open the center opening of the canopy. The peripheral edge of the flange is sandwiched between the flange and the locking projection, and the upper surface of the flange and the lower surface of the canopy are adhered to stably and firmly bond the both.
