Abstract: A container for liquids includes a mixing cartridge extending from a gasket into the neck of the container. The mixing cartridge is asymmetrically disposed with respect to the container to allow a piercing member extending into the container from the cap of the container to be disposed in the container without piercing the cartridge in a storage position. The cartridge is pierced and the contents of the cartridge are mixed with liquid in the container by relative movement of the cartridge and the piercing member of the container so that the piercing member will extend through the cartridge both to pierce the upper and lower surfaces of the cartridge and to provide a flow-path for the contents of the cartridge into the container.

Abstract: A multi-chamber test tube which includes a first and a second matched separate elongate tubular member, means to connect the members together defining a test tube means having a dual mouth, and a stopper having a first leg and a second leg extending from the stopper body and receivable within the first and second elongate tubular member and wherein a pathway is provided from a central cavity in the body of the stopper through each of the legs and wherein a one-way valve is provided in each of the leg paths which is normally closed yet yieldable to permit flow through the leg paths in response to an elevated pressure in the cavity relative to the interior of the test tube.

Abstract: A test tube having an inner tube that allows one to insert a bar to create a dark background is described. This system is actually an ordinary or screw-capped test tube with a smaller sized test tube inverted and fused to the bottom. The design permits a thin layer of any agar medium to solidify around the inside edge of the larger tube. The colonies developed in the agar can then be easily counted by creating a dark background by inserting a dark colored rod through the opening of the inner tube.Alternatively, a permanently dark-colored inner tube can be inverted and fused to the bottom of the outer tube. In this case, it is not necessary to insert a rod to create a dark background and the enumeration of microbial colonies is as easy as the method described above.

Abstract: A sample leveling device is described, for use in high speed liquid sampling systems, which comprises an insert cup capable of being removably located inside the open end of a liquid sampling tube, the cup being so shaped that, upon full or partial inversion of the tube and cup assembly from a datum position in which the open end of the tube is uppermost, the cup receives liquid held in the tube and retains the liquid when the tube is returned to its original position. The insert cup is so shaped that when it is inserted into a sampling tube its lower closed portion is offset from the line of travel a sampling probe would follow when sampling blood from the sampling tube. It is convenient to arrange the center-line of the insert cup co-axial or near co-axial with the center-line of the sampling tube into which the insert cup will be inserted.

Abstract: A compound vessel is provided which has many decorative and functional applications. The compound vessel is formed of a transparent material and has a spheroidal main body. The main body is comprised of spheroidal inner and outer walls with an annular space defined therebetween. The annular space constitutes an outer vessel of the compound vessel and the space contained by the inner wall constitutes an inner vessel of the compound vessel. The outer and inner walls join at one extremity of the spheroidal main body of the compound vessel to close the outer vessel and form the periphery of a generally circular mouth opening into the inner vessel, the inner vessel being otherwise closed. The outer wall terminates at an opposite extremity of the spheroidal main body of the compound vessel to form the periphery of a generally circular mouth opening into the outer vessel, the outer vessel being otherwise closed.

This lower flask compartment has padded walls, and is completely sealed by means of said cup portion, whereby the denture within the compartment may be treated by shaking the flask. The other compartment is connected to the neck of the flask and may contain rinsing fluid such as mouthwash or water; or by means of the sealing "cup" enables transfer of fluid from the upper compartment to the lower compartment.

Abstract: An amusement device, such as a die agitator, includes a closed liquid tight container having opposed end portions and a partition member located therein which divides the container into first and second chambers, with the first chamber being of greater volume than the second chamber. The partition member has an opening formed therein providing communication between the chambers and liquid fills the first chamber and a portion of the second leaving an air space or bubble in the second chamber. A buoyant game piece or die provided in the first chamber is used in the play of the game. The bubble in the second chamber accomodates expansion of the liquid in the container but is trapped in the second container so that it does not enter the first chamber.
