The present invention relates to a puncturing element which allows gradual puncturing of an openable liquid seal of a relatively small liquid filled chamber, thereby facilitating gradual pouring out and mixing of the liquid from the chamber.

An apparatus for draining a container comprises a vessel with a top opening configured such that the container in an upright orientation can pass downward into the vessel through the top opening. A knife assembly mounted under the top opening has a pointed upper end with right and left blades sloping downward and laterally away from the pointed upper end. The pointed upper end and the blades are configured to cut a flap in a floor of the container when the container is lowered through the top opening and pushed downward against the knife assembly. A push member pushes the flap upward from its remaining attachment along one side thereof as the container is pushed downward. The vessel can be mounted on a stand and include vertical exterior grooves configured to engage corresponding vertical stand members to prevent rotation of the vessel with respect to the stand during use.

A bracelet or flexible band comprised of a flexible member that on one end is interconnected to a knife and on another end, is connected to a sheath that selectively receives the knife in the locking fashion. When needed, the knife is rotated within the sheath to facilitate release thereof from a lock that is integral with the sheath. Once removed from the sheath, the knife can be used for self-defense, cutting rope or cord in an emergency situation, or for general utility cutting tasks.

A can opening system and method for removing the contents of a plurality of cans. The can opening system includes a housing adapted to receive a can and shield an operator from equipment within the housing, a top clamping assembly within the housing adapted to clamp onto a top edge of the can, a bottom clamping assembly within the housing configured to clamp against a lower side of the can, a punch cutter above the top and bottom clamping assemblies for extracting and retaining a lid of the can, and a punch tip within the housing adapted to puncture a bottom of the can and dispense the remaining contents of the can. The can opening system is adapted to remove up to about 90% of contents of a can for materials having a viscosity up to about 250,000 Centipoise.

Embodiments are directed to a puncture device that is adapted to puncture an array of beverage cans with a single actuation. A pivot arm rotates relative to a base that holds the array of beverage cans. The arm may include teeth that may be advanced or pushed into the array of beverage cans when the arm is rotated, thereby forming auxiliary openings in each of the cans. The punctured cans may be removed from the device and opened by a tab at a top end. This may create a vent that allows fluid to quickly expel from the auxiliary opening.

A puncturing device for pressurized containers comprises an elongated housing member defining an elongated cavity with openings at first and second ends thereof for receiving an inverted pressurized container at the first end, the housing member including an attachment member for securing the second end of the housing member to a collection receptacle. A non-sparking puncturing member, is mounted within the housing member for piercing a nozzle-end of the pressurized container at its domed top. A counter records each action of the puncture pin. Gases and residual contents are released into the receptacle through the hollow core of the puncture pin. An auxiliary support member is mounted on the housing member for stabilizing relative movement between the housing member and the receptacle. A force-applying apparatus is mounted on the housing member for forcing the pressurized container onto the puncture pin.

A device for unstopping a stopped specimen vessel that contains a liquid specimen such as blood is equipped with a mechanism which sucks and captures particles floating around the opening of the specimen vessel and prevents contamination of the specimen. The unstopping device grips a vessel and the stopper of the opening of the vessel, and removes the stopper from the opening of the vessel by changing the relative distance between the vessel-gripping mechanism and the unstopping mechanism. The unstopping device is equipped with: suction holes for sucking therethrough the gas which is present around the opening and contains liquid or solid particles; a pipeline which is connected to the suction holes and through which the sucked gas and particles are led downstream; a suction device connected to the pipeline; and a spirally flexed pipeline part disposed between the pipeline and the suction device.

A handheld puncturing tool which may be used as a hand-operated puncturing tool for puncturing a container or opening a bottle. An individual's hand motion and action of piercing and pressing through a container with a handheld puncturing tool may be fast and easy for the individual. At one end of a handheld puncturing tool, a claw-shaped prong protrudes. And, protruding along the elongated body of a handheld puncturing tool may be a first sharp-ended tooth prong and a second sharp-ended tooth prong. With the sharp-ended prongs and the light weight of the handheld puncturing tool, an individual may easily operate the handheld puncturing tool to puncture a container and create a venting hole which directs airflow into the container, which reduces any vacuum effect potentially caused when the second sharp-ended tooth prong pierces the container.
