The invention relates to a method for producing a lid for closing a container, the lid reduces the risk of a user's injury when opening the container while being producible at relatively low costs. The method comprising the steps of providing a preform of the lid (10), wherein the preform of the lid (10) has opposing first and second sides (11, 12), wherein the first side (11) faces towards the inside of the container when the lid (10) is affixed to the container; forming a bead (20) in the preform of the lid (10), wherein the bead (20) extends out of said second side (12) in an axial direction from said first side (11) towards said second side (12), wherein the bead (20) comprises two radially spaced apart side wall portions (22, 24) and a bridge portion (26) connecting the side wall portions (22, 24); thinning the side wall portions (22, 24) of the bead (20) at least partially, thereby elongating the side wall portions (22, 24); forming a score line (30) in the bridge portion (26) of the bead (20) on said second side (12); and flattening the bead (20) such that the two thinned side wall portions (22, 24) collapse, thereby providing the lid (10).

The present invention relates to a metallic overcap with latches, being applied in packaging with lids, which closes and guarantees the tightness of the packaging, allowing for retamping and guaranteeing the useful life of the filled product after opening the primary cover in packaging. of different types of materials, such as: steel, aluminum, fibralate, plastic, among others.

A tab stock feeder assembly for a press includes a plurality of support elements, a plurality of rotating elements, and a number of operative elements. Each rotating element is rotatably coupled to an associated support element. Each operative element coupled to at least one of the support element or one of the rotating element and wherein each the operative element is structured to be engaged by a rotating element. The tab stock feeder assembly further includes a wear reduction assembly including a plurality of wear reducing elements. A plurality of support elements have at least one wear reduction assembly wear reducing element disposed between a rotating element and the associated support element.

The present invention relates to a testing lid for testing the stroke of a holding plate of a closure head of a can closing device for cans, in particular beverage cans, the testing lid comprising: an edge portion provided for positioning onto a can edge, in particular for additional crimping with the can edge; and an inner portion, in which one or a plurality of testing pins are arranged in a force-fitting manner, the testing pins being displaceable by the holding plate in the direction of stroke while a stroke of the holding plate is taking place. The invention additionally relates to a method of testing the stroke of a holding plate of a closure head of a can closing device for cans making use of the testing lid according to the present invention.

A sheet metal lid has a rim portion removably secured and sealed to a container and the lid includes a vent button having a top wall portion surrounded by a side wall portion and an outwardly projecting flange portion. The flange portion of the button has a short arcuate score or shear line extending substantially into the sheet metal, and additional score lines extend into the flange portion at lesser depths to protect a coating on the inner surface of the lid. A resilient sealant material may be bonded to the inner surface of the vent button, and the opposing sheet metal portions of the score line form a small gap for releasing a vacuum or pressure from the container in response to a controlled downward pressure on the top wall portion of the vent button.

A tear-off lid with a curled edge of the removal opening is formed such that before the edge is curled, a plastics layer provided as a band of low thickness and preferably only 0.1 mm thickness is applied to the collar of the lid ring. In this way, a good seal of the cut edge of the tear-off lid is produced economically and with the possibility for production at a high rate.

A pull tab crown for a bottle or other container provides an opener secured to the top of the crown. The crown has an annular skirt with an annular edge. Score lines extend from the opener assembly to the skirt. One of the score lines is curvilinear and terminates at the annular edge. A second score line has a segment that extends from the opener assembly to an endpoint substantially spaced from the bottom annular edge of the skirt.

A sealing system is for containers, in particular of the type that envisages sealing with an aluminum cap. Forming equipment of a cap or seal of weldable sealing material is for the application on the mouth of a container. The equipment includes at least one cutting device (48) of a disc or sheet of the sealing material from a web of the sealing material. The at least one cutting device (48) is arranged along the periphery of a cutting roll (30) and the cutting roll (30) is motorized so as to move the web of sealing material by traction along an operational path.

A stamping device and a multi-lane shell stamping system, wherein the stamping device is used for simultaneous stamping of multiple shells, including a plurality of stamping die sets arranged in an array. Each stamping die set includes an upper die and a lower die. The upper die is integrally formed, and the outer diameter of the upper die is larger than that of the lower die, and the bottom edge of the upper die forms a locating part for the curling of the shell to be processed. The device and system eliminates the movable locating cup, which can avoid the difficulty of mounting and dismounting the die due to the compact six-lane structure. It also adopts the method of directly increasing the diameter of the upper die, which not only avoids the mounting and dismounting of the locating cup, but also realizes the locating effect of the shell.
