A plug for use with a beverage container that can optionally be integrated into a sleeve. The sleeve can be made of a single layer of paper-based material that is embossed on one surface with protrusions that mimic the fluting of traditional single-layer corrugate. Some embodiments also have a second flat linerboard layer attached to the first embossed layer. The sleeve material can feature perforations that surround a protrusion making the plug removable from the sleeve. In addition, the flattened portion of the plug can contain a cutout portion that makes it easier for the user to grip a section of the flattened portion of the plug.

A poster tube closure includes a plug member for locating within an end of a poster tube. The plug member has a substantially planar closure surface with upper and lower faces, wherein a perimeter wall extends downwardly from the lower face for gripping the wall of a poster tube when inserted. The upper face has a frangible or weakened area arranged in use to be broken by user action to permit removal of the plug member and a visible indication of the breakage.

The hybrid plug is a single component replacement for three components, the paint plug, conventional plug and capseal in a drum closure. It is formed from a single sheet of metal and has a plug portion and a capseal portion which vary in thickness. The plug portion has a collar and an externally threaded wall with a plug gasket disposed on a plug gasket seat. The capseal portion is provided with ears and scoring to enable separation from the plug portion and with a lining on the inner wall of the capseal portion to safeguard against plug gasket failure. The capseal portion may be recessed at intervals to form dimples which hold the hybrid plug in place in an automated insertion process. The hybrid plug provides a passage for air and gases during paint curing and leak testing without necessitating removal.

A threaded plug includes a structure which extends along an axis and includes a head, a body provided with an outer thread, and a clamping flange inserted between the head and the body; wherein the head includes, along the axis, at least one first portion having an outer lateral surface which features a first profile and at least one second portion having an outer lateral surface which features a second profile which is not coincident with the first profile.

An apparatus is proposed for applying and removing protective caps (1) to and from the ends of elongate members (6). The protective cap (1) has a hard base portion (5) and a cover portion (2) of flexible, resilient material, extending from the base portion (5) and operative to cover a portion of an outer surface of the elongate member (6). The apparatus comprises: a gripping mechanism (44) operative to grip the hard base portion (5) of the protective cap (1); a drive mechanism, connected to the gripping mechanism (44), operative to move the protective cap (1) to and from the end of the elongate member (6); and a tool operative to perform at least one of the operations of (i) unfurling the cover portion to secure it to the outer surface of the elongate member, (ii) furling the cover portion to detach it from the outer surface of the elongate member.
