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.

A coupling device for mounting onto the spout of a faucet is disclosed. The device is connected or connectable to a hose and includes an elastomeric sleeve and a clamp assembly. The clamp assembly includes a housing and a pressure applying member. The housing has a cavity holding the sleeve between a back wall and the pressure applying member. The sleeve receives the externally threaded spout. The pressure applying member is movable to a closed position to compress the sleeve tightly about the spout to releasably secure the device to the faucet. The pressure applying member is also movable to an open position to release the spout from the sleeve. Also disclosed is a cap device for releasably sealing an externally threaded mouth of a bottle or other hollow vessel and making use of an elastomeric sleeve and a clamp assembly similar in many respects to the coupling device.

The present invention relates to a pail body having a pail end defining a pail opening, a lid closing the pail opening, and a clamping ring clamping the lid onto the pail end, wherein the clamping ring comprises a lever connected to the ends of a split clamping ring, which lever in a closed position clamps the split clamping ring onto the pail end, and in an open position widens the ring, and spring means connecting the lever to at least one of the ring ends, to the clamping ring, and a method for applying the clamping ring to a pail body.

An openable securing ring for holding a lid or similar closure on a container has a latch mechanism arranged to secure ends of the ring releasably together at a circumferential break. A circumferentially extending recess is provided at a radially inner portion of the latch mechanism so that the radially inner portion is of reduced axial external thickness and provides relief for stable stacking of a first container on top of a second container when the securing ring is attached to the second container. A radially inner edge of a locking lever side wall may lie radially outward of the inner diameter of one ring end to define at least part of the reduced thickness radially inner portion.

A multi-function cup having a detachable cup mouth includes a cup body having a cup mouth. The cup mouth is provided with a sealing cover device. The sealing cover device includes a cup cover, an engaging hoop, an engaging ring, and a buckle. The engaging hoop is attached to an inner wall of the engaging ring. The engaging ring has a notch. The buckle is connected with the engaging ring. Two sides of the buckle are connected with the engaging ring at two sides of the notch. The cup mouth is provided with a flange extending upward. The cup cover is mated with the flange. The buckle is buckled with the engaging ring to reduce the engaging ring for the engaging hoop to fasten the flange of the cup mouth. Because the cup is made of silicone, it is easy and convenient to place articles into the multi-function cup.

A truncated-cone-shaped container body for a truncated-cone-shaped drum for packaging has an upper edge delimiting an upper inlet mouth. The upper edge has a first folded portion projecting outwardly with respect to a lateral wall of the truncated-cone-shaped container body. The first folded portion is in one piece with the lateral wall. The first folded portion serves as a support for a lid and allows stackability of a plurality of drums one inside the other. The truncated-cone-shaped container body is made of kraft fibre. A truncated-cone-shaped packaging drum has the truncated-cone-shaped container body, a bottom, a lid, and a clamping collar for fastening the lid to the truncated-cone-shaped container body.
