Abstract: A pull-tab for an easy-to-open can container is mounted on a lid provided at an opening of a partially-open type container that contains a liquid such as a refreshing beverage. The pull-tab is fixed by a rivet at a predetermined portion of a removable portion surrounded by a score provided on the lid. A dish-like or bowl-like recessed portion is formed around the peripheral edge of a rivet insertion hole of the pull-tab. The peripheral edge of the rivet insertion hole is turned upward along the peripheral wall of the recessed portion to form a horizontally turned portion. A reinforcing edge is provided around the entire peripheral edge of the pull-tab with the exception of the distal end portion at a portion thereof at which the rivet insertion hole is provided. The length of this portion at which no reinforcing edge is provided is made smaller than the outer diameter of the recessed portion. Therefore, it is possible to efficiently prevent the pull-tab coming off the rivet when the container is opened.

Abstract: A tamper indicating closure has a hermetically sealed membrane which prevents contamination. The membrane is held within a closure cap for easy application to a container neck prior to being heat welded to the container. A disc secured to the membrane together with a pull ring serves to sever the membrane and open the sealed container. A lid functions to cover the membrane and disc until the seal is to be broken and thereafter to close the container when not in use. The only way to gain access to the contents, i.e. to the interior of the container, is by tearing the membrane. The means for tearing the membrane substantially covers the membrane except for a very thin edge portion thereof adjacent the spout of the container. This insures that tearing for the purpose of opening will substantially completely remove the membrane and also insures that access to the membrane for tampering purposes is very difficult.

Abstract: This relates to a dispensing cap including a cap body and a cover which are connected together by suitable hinges so that the cover may swing between a fully open position and a fully closed position. In association with the hinges, there is a strap which connects a bendable wall portion of the cover to the cap body. The strap, in the open position of the cover, is located on one side of hinge centers and as the cover is swung towards a closed position, the strap passes through an overcenter position where a greater length of strap is required, thus effecting bending of the cover wall portion between the hinges to provide a spring effect. In the closed position of the cover, the strap is on the other side of the hinge center and bending of the cover wall portion is held to a minimum.

Abstract: A method of sealing an open end of a plumbing drain pipe for leak testing the pipe comprises the steps of terminating the drain pipe in an open externally threaded end; and attaching a screw cap to the externally threaded end portion. The screw cap comprises a body including a cylindrical portion having internal threads for attachment to the externally threaded end portion of the drain pipe; and an end wall enclosing one end of the cylindrical portion and defining, with the cylindrical portion, a cavity. The end wall has a generally planar internal surface. A thick circular sealing disk, disposed within the cavity, has a diameter sufficient to cover the open end face of an attached pipe. An anti-friction washer is disposed between the sealing disk and the internal surface of the end wall which allows the sealing disk can rotate independently of the body; such that, as the body is threaded onto a pipe, the sealing disk does not rotate after encountering the pipe's open end face.

Abstract: A container closure of the so-called spout type comprises a female element and a male element. The female element is attachable to a flexible container wall section, and the male element is attachable to an opposite wall portion, such that a container, for instance a four sided edge sealed pouch of the giant size type, is closable by arranging the female element and the male element in a sealing engagement for forming a closure. An axially operating arrangement for providing relative axial movement between the male and female elements, for instance of the bayonet type is arranged for providing an axial or relative movement of the female and male elements, such that an axial sealing ring will be compressed. The sealing of such ring may be supplemented by the sealing effect obtained by means of the ribs and grooves of the device. As a further specific feature the seal may include bacteria killing material, for instance of the ZEOLIT-type.
