Abstract: The present invention relates to a packaging container designed to transport an inner container containing a liquid. The packaging container has at least one sealing multi-layer comprising a first water soluble film and an absorbent material. The inner layer of the packaging container is the water-soluble film that forms the boundary between the cavity that hold the inner container and the packaging container. When the liquid leaks from the inner container while in the packaging container, the liquid passes through the water-soluble film. When the liquid contacts the absorbent material, the absorbent material absorbs and immobilizes the liquid material. This immobilization prevents the liquid from escaping from the packaging container. The present invention also includes a security feature, an apparatus to identify where or whom the liquid was obtained from and/or tests to be conducted, and/or the ability to extract the liquid from the absorbent material.

Abstract: The present invention is an expanding device for supporting grinding sleeves. The device has a cylindrical member with an outer surface, an interior chamber, an expanding chamber, and a locking mechanism. The outer surface receives the grinding sleeve and has a first outer diameter of D. The interior chamber receives a rotatable shaft and has a second outer diameter of I, which is less than D. The expanding chamber comprises an expanding material that expands and contracts based upon pressure applied thereon and has a third outer diameter of H and an inner diameter of J, wherein H and J are both greater than I and less than D. The locking mechanism has an open position and a closed position and requires no hand tool to alter its position. When the locking mechanism is in the open position the locking mechanism applies a pressure P to the expanding chamber so the first outer diameter is D, the second outer diameter is I, the third outer diameter is H, and the inner diameter is J.

Abstract: The present invention relates to a packaging container designed to transport an inner container containing a liquid. The packaging container has at least one sealing multi-layer comprising a first water soluble film and an absorbent material. The inner layer of the packaging container is the water-soluble film that forms the boundary between the cavity that hold the inner container and the packaging container. When the liquid leaks from the inner container while in the packaging container, the liquid dissolves the water-soluble film. When the film is dissolved, the absorbent material is released to absorb and immobilize the liquid material. This immobilization prevents the liquid from escaping from the packaging container.
