A leak proof safety shield/guard for a syringe is herein disclosed. The shield/guard provides for not only protection of the syringe from a damage and abuse in the storage and handling, but also protects the health care professional from contact with the used needle and any of the tissues or fluids adherent thereto. Moreover, any and all fluids that are initially contained within the syringe, or subsequently collected from a patient, are also isolated from inadvertent discharge or loss. This device achieves such objectives by providing a sealed protective guard that retains its integrity subsequent to use of the syringe. Additional enhancements to the device of this invention include a locking mechanism that prevents re-use of the syringe; and, additionally causes the syringe to be rendered physically inoperative.

The container system further includes a main component having a main container including an opening and a cavity in fluid communication with the opening, a coupling means located at the opening of the main container for receiving and fluidly coupling with the neck portion of the concentrate container, and a discharge mechanism operatively associated with the coupling means, wherein the discharge mechanism is adapted for operatively engaging the sealing means to initiate the release of the concentrate from the concentrate container into the cavity of the main container.

A dispenser for powdered, granular or related fluent materials. The dispenser includes a reservoir and an actuation mechanism that together define a housing, or enclosure. The reservoir sealingly contains a fluent material such that the contents are not easily contaminated or tampered with. User-imparted relative movement between cooperating parts of the actuation mechanism and reservoir enables a predetermined and repeatable quantity of the fluent contents to be discharged from the dispenser and onto a desired area, such as a food product. The dispenser is configured as a disposable device such that, after depletion of the fluent material contents arising out of a multiplicity of uses, it can be thrown away.

A vacuum breaker arrangement for use with a container includes body parts holding a resilient valve member captive.
