摘要： A dispensing cartridge (20) in accordance with the present invention is relatively simple in configuration while minimizing leakage of the fluid (28) and eliminating problems associated with chemical attack of the O-ring (112) by the fluid (28) in the dispensing cylinder (22). The air vent (41) is configured as a tortuous path, which in a pre-staged position allows air to freely escape along the spiral path along the circumference of the plug (26). As the piston (24) contacts the fluid (28), the forward motion of piston (24) is resisted by the high backpressure created by the small effective diameter and relatively long length of the spiral path. Once the piston (24) contacts the fluid (28), the spiral plug (26) is pushed into the piston (24) closing the spiral path. By controlling the fluid flow, the amount of fluid backflow through the piston (24) is minimized if not eliminated, thus eliminating the need for an annular overflow chamber. To improve the sealing of the piston (24) within the dispensing cartridge (20), the piston (24) may be provided with one or more radially extending sealing lips (64, 66) that can be used in lieu of or in conjunction with an O-ring (112).

摘要： A dispenser (10) for manually dispensing pasty, semi-fluid products that must be applied with control and accuracy incorporates a unique integral trigger (22) and pawl (24) drive mechanism (20), in which the drive (20) is activated by a trigger (22) or actuator. A product dispensing cartridge is attached to the front of the dispenser (10) via a cartridge holding mechanism. As the trigger (22) is depressed, the pawl drive mechanism (20) engages and advances a plunger (40) into the product container, contacting and advancing a piston within the cartridge which in turn advances and expels product from a cartridge dispensing outlet. At the completion of the stroke, the trigger (22) is released and the drive mechanism (20) disengages the plunger (40), the disengagement interaction between the drive mechanism (20) and the plunger (40) causing the latter to move rearwards. A floating gripper (52), disposed on the plunger, limits the amount of this rearward movement, the effect of which is to decompress the product cartridge and thus prevent drooling after the completion of dispensation.

摘要翻译：用于手动分配糊状的半流体产品的分配器，必须以控制和精确的方式应用，其中包含独特的整体扳机和棘爪驱动机构，其中驱动器由触发器或致动器激活。产品分配盒通过盒保持机构附接到分配器的前部。当触发器被压下时，棘爪驱动机构将柱塞接合并推进到产品容器中，使柱塞内的活塞接触并前进，从而使产品从盒分配出口进入并排出。在行程完成时，触发器被释放，并且驱动机构使柱塞脱离，驱动机构和柱塞之间的脱离相互作用导致后者向后移动。设置在柱塞上的浮动夹具限制了这种向后运动的量，其效果是减压产品盒，从而在分配完成之后防止流口水。

摘要： A single dose dual fluid cartridge for use with a hand-held applicator is disclosed. With the disclosed dual fluid cartridge, a hand-held applicator may be used to dispense and mix two component end products (e.g. an adhesive). Such an ability to dispense a single dose of a two component end product is especially useful in the dental field.

摘要： A dual fluid cartridge assembly (30) is adapted to be used with a conventional caulking gun (20). The dual fluid cartridge assembly includes an outer cartridge (32), a piston seal and delivery tube (36), an upper piston seal (38) and an inner cartridge (34). The outer cartridge includes a cartridge outlet (40) for dispensing fluids and as configured to accept conventional mixing nozzles. Fluids are back-filled through the cartridge outlet into the inner cartridge and the outer cartridges. In order to prevent trapped air pockets during the filling of the fluid in the inner cartridge, one or more slots (54) are formed in a base plate (42) of the inner cartridge.

摘要： A dispensing cartridge with a vented piston (20) is disclosed. The piston (20) includes a piston shell (22) and a bleed plug (24). The arrangement of the piston shell (22) and the bleed plug (24) allows air to be vented though the piston (20) until all of the air is vented out of the dispensing cartridge. With the air vented out of the dispensing cartridge, the piston (20) self- actuates into a closed sealed position in which the bleed plug (24) forms a seal with the piston shell (22) to prevent further fluid from flowing between the two elements.

摘要： A dual fluid cartridge (20) for storing and dispensing fluids in unequal ratios is disclosed. The dual fluid cartridge (20) disclosed defines two fluid chambers (42,44) for a fluid to be held in greater amount and defines another fluid chamber (40) for a fluid to be held in lesser amount. The two fluid chambers (42,44) holding the fluid of greater amount are in fluid communication with one another through a delivery channel (46). Because of this arrangement, the dual fluid cartridge (20) is very suitable and highly effective in situations where a dual fluid cartridge is needed to store and dispense fluids of unequal ratios ( e.g. a 10:1 ratio, a 9:1 ratio, an 8:1 ratio, a 7:1 ratio etc.). With such an arrangement, the amount of space wasted in the cartridge is minimized, which maximizes the amount of fluids that can be stored in the cartridge. As a result, the total final product that can be dispensed from the dual fluid cartridge is also maximized.
