Abstract: A dispensing system provides for the delivery of a contained substance sealed in a Dispensable Containment Vessel (DCV) into a target container, which can contain another substance. The dispensing system includes a dispensing adaptor (Dispensing System) that couples the DCV to the target container so substances can be transferred between the containers without escaping or contacting the user. When the DCV is activated from a secure conformation into a dispensing conformation, the dispensing adaptor sealably engages the target container and portions of the dispensing adaptor place stress on a barrier, which frangibly tears along defined tearing paths to form vents or flaps that are forced apart against the dispensing adaptor, allowing the contents of the DCV to enter the target container. The dispensing conformation also facilitates the efficient mixture of substances and allows them to travel between the containers to flush residual DCV contents into the target container.

Abstract: An enclosed implantable material mixing system is described herein. The system uses an enclosable vial or container into which bone cement mixture may be mixed by agitation. The bone cement mixture may be made of a combination of polymer and liquid monomer, but because of the method of agitation, e.g., shaking the vial and its contents, the ratio of the monomer-to-polymer is critical. A desirable weight ratio of the monomer-to-polymer is about 0.3 to about 1, and more preferably about 0.53 to about 0.63, and is more preferably about 0.57. The vial or container may also include a free-floating, or disassociated, agitator to aid with the mixing process. To prepare the composition, the vial and its contents may be capped and shaken until the mixture dissolves completely. The contents of the vial are then allowed to sit and undergo a solvation process at the end of which the mixture may be shaken again and then poured out for use.

Abstract: A fluid mixing system is provided to permit rapid mixing of a prestored powdered substance such as powdered milk with a liquid in which, in one embodiment, baby bottles are stacked one atop the other in fluid communication, with an internally carried stemmed disk preventing powdered contents of the upper bottle from entering the liquid carried by the lower bottle until the stemmed disk is dislodged from the aperture between the bottles, the stemmed disk falling into the lower bottle such that the mixing can occur without opening or separating the two bottles. The invention thus allows the separate storage of two pre-measured fluent materials within the same container, and to facilitate the mixing and dispensing of those materials at a later time without opening the container. The benefits of this are that the user can prepare in advance mixtures of materials which, if stored in a combined state, will sour, harden, or otherwise become unusable without mixing the two ingredients until the time of use.

The inner capsule includes an elongated pestle telescopically extended into an open ended cap including a resilient, annular skirt formed with an annular sealing lip sized for frictional, gripping engagement with the pestle to define a storage chamber therebetween for storing a liquid component of the amalgam. The inner capsule may be made by subjecting the cap to a partial vacuum, inserting a charge of such liquid component therein, and registering one end of such pestle in sealing engagement with such sealing lip. Thus, when the assembly is returned to atmospheric pressure, the partial vacuum trapped in the cap will provide for a pressure differential across the pestle drawing it into the cap to fill the space therein.

Abstract: Liquid contents such as water are stored in a heat-resisting can body having an openable section formed on an upper part thereof. Other material is stored within the can body while being separated from the liquid contents and, when the can body is heated above a predetermined temperature with the openable section opened, the separation between the stored material and the liquid is removed and the liquid can come in contact with the stored material. When the openable section is closed while the can body is heated, the stored material is kept separate from the liquid even during a sterilizing process but, when the can body is heated with the openable section opened, the separation between the stored material and the liquid is removed, and consequently the contents are mixed together. This permits the stored material to be preserved from the liquid until the contents of the can body are ready for use.

Abstract: A sugar stick is provided to stir coffee until a desired sweetness is attained.
