A system for opening a secure specimen sample bottle includes a base having a first area and a first raised hollow portion for receiving and holding the specimen sample bottle. The first raised hollow portion has a groove formed along an outer surface thereof. The system includes a cutter for cutting a first portion of the specimen sample bottle. The cutter has a handle at a first end and a second end portion that receives the first portion of the specimen sample bottle and a blade for cutting the first portion. The second end portion has a flange with a raised rail formed along an inner surface of the flange, with the raised rail being received within the groove to couple the cutter to first raised portion during performance of a cutting operation.

Improved systems and methods for cutting a can are provided. The system includes a can cutting device having a main body, a can support assembly, and a cutter. The can support assembly has a can support rotatable about a can support longitudinal axis. The can is positionable in a mounted position that holds the can body in contact with the can support at least at a cutting location. When the can is positioned in the mounted position, the can is rotatable about a can axis of rotation. When the cutting surface is in contact with the can body supported by the can support at the cutting location and the can is rotated about the can axis of rotation, the cutting surface cuts the portion of the can body at the cutting location.

A secure specimen sample bottle includes a base container for receiving a specimen. The base container has a plurality of locking protrusions formed along an inner surface of the base receptacle. A bottle includes a lock ring that has an upright spire structure that has a closed top end and the opposing open bottom end including a plurality of flexible fins that are configured to interlockingly mate with the locking protrusions so as to prevent removal of the lock ring relative to the base container upon engagement of the flexible fins to the locking protrusions. A removable cap is coupled to the lock ring.

An adjustable can opener that includes a space adjustment assembly disposed between a main body and a washer set is provided. The space adjustment assembly includes a retaining base coupled to the main body and an adjustment shifting block fitted on the retaining base. The retaining base has a stepped portion having multiple steps. The adjustment shifting block also has a stepped portion having multiple steps. Responsive to manual rotation of the adjustment shifting block, the position where one of the steps of the adjustment shifting block is in contact with a respective one of the steps of the retaining base is changed to adjust the space between a traction wheel and a cutter wheel of the can opener.

A device for cutting the foil on a bottle, including a circular shaped body that has a top end and a lower end, wherein the body includes a lip at the top end that protrudes inward such that it can rest on top of the mouth of a bottle, and a plurality of cutting elements attached to the lower end of the body on the inside, such that when the outside of the body is pressed by the hand of a user the cutting elements make contact with foil wrapped around the top end of a bottle, and where the distance from the top end of the body to the lower end is sufficient to enable the cutting elements to make contact with the foil below the bead of the bottle.

A can opener includes a pair of handles attached for pivotal movement between an open position to receive a rim of a can and a closed position to trap the rim between a cutting blade and a traction wheel. A crank having a handle is positioned on one side of the pair of handles and includes a cavity formed in the crank for housing a ratchet assembly configured to drive a traction wheel located on the opposite side of the pair of pivoting handles.

An adjustable can opener includes a space adjustment assembly disposed between a main body and a washer set. The space adjustment assembly includes a retaining base coupled to the main body and an adjustment shifting block fitted on the retaining base. The retaining base has a stepped portion consisting of at least two steps. The adjustment shifting block also has a stepped portion consisting of at least two steps. Thereby, by rotating the adjustment shifting block, the position where one of steps of the adjustment shifting block is mated with a corresponding one of the steps of the retaining base may be changed to adjust the space between a traction wheel and a cutter wheel.

A can lid cutter is a can lid cutter that cuts a lid from a can by cutting a cylindrical raised portion of the outer periphery at the upper end of the can, the can lid cutter includes: a main body having a circular recessed portion formed in a circular shape for receiving the raised portion; a blade provided in the main body to cut the raised portion; an operation portion for pressing the blade toward the raised portion in a state where the main body is mounted on the can; and a tab holder that is provided inside the circular recessed portion and holds a stay-on-tab of the can in a state where the main body is mounted on the can.
