    摘要： A mold unit (30) defines an elongate cavity (70) and has an injection inlet port (90) for a viscous material at one end of the cavity and an injection outlet port (92) at the other end of the cavity. The mold unit includes a gas vent formed by a gap (G2) between two parts of the mold unit. The gap extends continuously or intermittently in the length direction of the the mold unit, while penetrating through the mold unit in the thickness direction such that it provides fluid communication between an interior space and an exterior space of the cavity. The gap is shaped such that, although gasses pass through, the viscous material does not pass due to fluidity resistance of the viscous material resulting from its viscosity. As a result, the gas vent acts to block leakage of the viscous material while permitting degassing of the viscous material.

    摘要： A method for transferring a viscous material from a container into a dispensing syringe having first and second ends, the second end being a discharge port smaller than the inner diameter of the main body portion, includes inserting into the syringe a plug configured to permit gas flow in only one direction to divide a chamber within the syringe into a first sub-chamber in communication with the discharge port and a second sub-chamber in communication with the first open end of the syringe. Then, a rod is inserted into the syringe from the first open end of the syringe to engage the plug, and the viscous material is extruded from the container and through the discharge port into the first sub-chamber of the syringe. While the first sub-chamber is being filled with the viscous material, the plug and the rod are moving away from the discharge port.

    摘要： A method for transferring a viscous material into a syringe that has a plug dividing a syringe interior into a first sub-chamber and a second sub-chamber, where a radial clearance exists between the plug and the syringe, includes transferring the viscous material from a container into the first sub-chamber to fill the first sub-chamber while allowing air initially present within the first sub-chamber to flow into the second sub-chamber via the radial clearance, and flowing a first volume of the viscous material into but not through the radial clearance such that the viscosity of the first volume of the viscous material and the radial clearance cooperate to block a flow of a second volume of the viscous material into the radial clearance and prevent the second volume of the viscous material from leaking from the first sub-chamber into the second sub-chamber.

    摘要： A plunger is fittable within a cylinder of a pneumatic dispenser that discharges a viscous material. The plunger has a first portion located at the front, and a second portion located at the rear. The second portion is a hollow structure and has a circumferential wall. An inner circumferential surface of this circumferential wall has a tapered surface. The circumferential wall has a thickness dimension that decreases in the axial direction moving away from the first portion. Therefore, the circumferential wall easily displaces in the radial direction, because the bending stiffness decreases in the axial direction moving away from the first portion. The first portion is a solid structure that is more rigid than the second portion. The first portion also has a partition wall surface that separates the inner chamber of the second portion from the solid section of the first portion.

    摘要： A cartridge usable in a viscous-material dispenser includes a cylinder, a plunger in the cylinder, and a plurality of ribs extending radially from an outer surface of the plunger to an inner surface of the cylinder. The ribs are circumferentially separated by a plurality of clearances, and the ribs and the clearances extend in an axial direction. Each of the plurality of clearances is defined by two adjacent ribs. The ribs and clearances are configured to allow the venting of gas through the clearances during a beginning of a cartridge filling operation and to impede the movement of the viscous material through the clearances during a remainder of the cartridge filling operation such that, at an end of the cartridge filling operation, the ribs and bodies of the viscous material in the clearances form an airtight seal between the plunger and the cylinder.

    摘要翻译： 柱塞可装配在排放粘性材料的气动分配器的气缸内。 柱塞具有位于前部的第一部分和位于后部的第二部分。 第二部分是中空结构并且具有圆周壁。 该圆周壁的内圆周表面具有锥形表面。 圆周壁具有沿轴向方向移动远离第一部分的厚度尺寸。 因此，由于弯曲刚度在远离第一部分的轴向方向上减小，所以圆周壁容易沿径向位移。 第一部分是比第二部分更刚性的固体结构。 第一部分还具有将第二部分的内室与第一部分的实心部分分开的分隔壁表面。
