A tube clamp may include a tube body, an abutting block, and a clamping member, and a pivot connecting portion is formed at a lateral edge of the tube body. A through hole penetrates through a lateral surface of the tube body, and each of two lateral edges of the through hole has a first locating protrude having a stepped surface. The abutting block is slidably installed in the through hole, and each of two lateral sides of the abutting block comprises a second locating protrude, and the two second locating protrudes are respectively coupled with the two first locating protrudes. The clamping member has a protruding portion and a pulling portion. Through pulling the pulling portion, the protruding portion is adapted to press the abutting block into an inner space of the tube body so as to achieve the clamping effect of the tube clamp.

A dispensing cap for a container such as a bottle or pouch. The nozzle of the cap is designed to connect a hose and the nozzle is connected to the cap base in a manner that allows the nozzle to operate like a valve. While the nozzle is in the closed position an air or liquid tight seal is made between the nozzle and cap base. While the nozzle is in the upright and open position the passage of air or liquid is allowed through the cap for the purpose of dispensing a liquid from within a container.

A temperature-controlled fluid processing system with accessory attachment mechanism includes an accessory annular ring feature a mounting surface and a tapered surface sloping toward a central axis of the ring feature and away from the mounting surface, and engaging components on the primary device, including concentric annular member and rotation plate. The annular member includes spaced apart through holes housing spring biased pins. The rotation plate surrounds the annular member, and includes one or more ramped inner surface(s). The plate is rotatable between an unattached position wherein the ramped surfaces apply no radial inward force to the spring-biased pins, and an attached position wherein each ramped surface displaces a pin inward through its corresponding through hole such that the conical tip of the spring-biased pin engages the tapered surface of the ring feature, thereby immobilizing the accessory with respect to a head unit of the fluid processing device.

A coupling device is provided for mounting onto a faucet having an externally threaded portion terminating in a free end. The device includes a pair clam-shell shaped members pivotably connected to each other to form a housing enclosing a tubular connector member having a connector at one end for connection to a hose. A pair of opposed shoes, a washer and a pressure applying member are located within the housing. An actuator lever is coupled to the clam-shells to pivot them with respect to each other into various positions. In one position the shoes are brought into engagement with the externally threaded end portion to mount the coupling device on the faucet. In another position the pressure applying member moves the tubular connector member into engagement with the washer to compress the washer between it and the free end surface of the faucet to couple the faucet to it in a fluid-tight interface.
