The lever operating mechanism for air-pressure utilizing hot pots referred to in the present invention that have a simple construction of lever operating mechanism, is able to raise and collapse the lever and maintain the lever raised and collapsed condition extremely easily and smoothly, and achieves superb operability and satisfactory discharge because all the operations can be carried out simply by moving the free end of the operating lever up and down with only one finger. The lever operating mechanism of the air-pressure utilizing hot pot referred to in the present invention comprises a compression process in which the free end of the operating lever is raised from the operating lever contained condition, and the operating lever, arm, and inside lever are engaged and operated in linkage to bring the bellows pump into the compressible condition, an operating lever downwards movement process in which the operating lever is operated to move downwards and the bellows pump is pressed down during this compression process, an operating lever return process for returning the operating lever, a lever sliding process where the free end of the operating lever of this operating lever return process is raised more greatly than the operating lever in the compression process and the base end side end of the operating lever compresses to slide the base end side end of the inside lever forwards, an arm moving process where the arm base end side is moved to the inwards front of the lid as the inside lever moves forwards in the lever sliding process, an arm leaving process where the arm is allowed to leave from the operating lever, an operating lever collapsing process where the operating lever is contained after this arm moving process, and a lever containing process where the operating lever support rod portion of the operating lever collapsing process comes in contact with the inside lever pin portion and the inside lever is moved backwards together with the arm and the operating lever is brought into the contained condition.
An inexpensive, readily visible indicator for liquid levels in a vacuum bottle that includes a coating of reflective material to minimize radiation heat transfer from the interior of the vacuum bottle to the exterior of the assembly. The vacuum bottle assembly includes a container receiving the vacuum bottle and a transparent or translucent window is located in the side wall of the container and in alignment with an interruption in the reflective coating. An indicator is located within the vacuum bottle and is aligned with both the windows and the interruption so as to be visible therethrough to provide an indication of the level of the liquid contained within the inner liner of the vacuum bottle.
The present invention relates to a liquid dispensing apparatus comprising a liquid container, a base and an air pressure device; the liquid container has an internal reservoir for containing the liquid and a dispensing conduit connected to a dispensing nozzle; a part of the dispensing conduit may be situated within the reservoir and is adapted to transfer the liquid from the reservoir to the dispensing nozzle; the base has a surface for holding a liquid receiver; the dispensing nozzle of the liquid container may be positioned above the surface of the base so that when the liquid receiver is situated upon the surface, the liquid from the dispensing nozzle will go into the receiver; the air pressure device is designed for creating pressurized air and is mounted in conjunction with the base; the pressurized device is connected with the internal reservoir of the liquid container, whereby upon operation of the air pressure device, pressurized air is supplied to the internal reservoir of the liquid container which causes the liquid within the reservoir to be transferred into and through the dispensing conduit and out of the dispensing nozzle.
A double-barreled syringe is provided which includes a mixing tip which is detachable after the tip is locked to the syringe body, so that the tip may be replaced by a locking cap. Locking occurs when a neck extending from the body between two shoulders is inserted into a bore in the tip (or, alternatively, the cap) and the tip is rotated so that two symmetrically opposed tabs attached to the tip are each received within a recess determined by a shoulder and a locking rib attached to the shoulder, and two diametrically opposed detents extending from the neck are each received within a recess in the bore surface.
