A container 10 for mixing and dispensing of material having a liquid receptacle 14 and a plunger 18. The receptacle 14 has a front portion 36 and the plunger 18 has a forwardly projecting sharp protrusion 42 having a shaft 72 which terminates in a sharp outer end 78, 82. Upon the plunger 18 being depressed the sharp protrusion 42 pierces a front portion 36 of the liquid receptacle 14 and the liquid in the receptacle 14 is pushed hydraulically through the front portion 36 into the main chamber 17. Thus the liquid contacts material in the main chamber 17 to form a mixture. The plunger 18 can continue to be depressed so as to break the front portion 36 of the liquid receptacle 14 away and then push the material in the main chamber 17 towards a dispensing nozzle 26. The main chamber 17 has a frangible membrane 22 at a distal end 13 thereof which is hydraulically broken by pressure applied from the material in the main chamber 17 so that the material can be dispensed from the container 10. The container 10 is particularly envisaged for use with mixing and dispensing of dental materials.

A container lid (2) can be removed from a mouth-neck section (106) of a container without the need for a tool. Following the breakage of a breakable thin-walled line (70) in a transition region (52), the breakage of a breakable thin-walled connection wall (68) in a side wall separation region (54) can be started sufficiently smoothly in the container lid (2). For this purpose, the breakable thin-walled line (70) formed in a side wall (10) in the transition region (52) is brought into a form in which at least a part thereof extends obliquely downwardly in a counterclockwise direction.

A spout for a container, wherein the spout includes a spout body and a spout counterpart. The spout body has a first zone, and the spout counterpart has a final zone. In the final position of the spout, an outlet opening arranged on the spout is open, providing a liquid communication through the spout body to and through the outlet opening. The final zone features a first subzone and a second subzone, arranged free of mutual overlap, allowing the spout to be arranged in its final position in two different configurations: a first configuration of the final position, where a reference subzone of the first zone is arranged to physically interact with the first subzone, and a second configuration of the final position, where the reference subzone is arranged to physically interact with the second subzone.

A closure for a container is provided with a top portion and a skirt depending from an outer periphery of the top portion. A generally circular rim extends downwards from the lower surface of the top portion. A liner is attached to the closure between an outer surface of the rim and an inner surface of the skirt. The liner is configured to provide a fluid tight seal for containers having varied neck dimensions and/or profiles. One or more projections extend into a space formed between the lower surface of the top portion, an inner surface of the skirt, and an outer surface of the rim, with the liner enveloping and being supported in the closure by the one or more projections.

A plastic cap, which is a highly producible one-piece type cap when molded, but becomes a two-piece type cap excellent in sealability and openability when used, and enables a small-diameter pouring opening to be formed, is provided. The plastic cap comprises: a cap body which is composed of a top plate section and a skirt section, has a pouring nozzle formed on an outer surface of the top plate section so as to surround an opening-scheduled portion, and is fitted and fixed to a container mouth; and a top lid composed of a top face, and a circumferential wall suspending from an outer peripheral edge of the top face. The top lid has, formed therein, a protrusion protruding downward from an inner surface of the top face and having an engaging portion on an outer surface thereof. The cap body has an inner plug formed therein. The inner plug is composed of an annular sidewall having an outer diameter enabling the annular sidewall to intimately contact an inner surface of the pouring nozzle; and a bottom formed at a lower part of the annular sidewall. The inner plug is formed integrally with the cap body via a breakable weakened portion at a position below a seal portion of the pouring nozzle having an inner diameter enabling the seal portion to intimately contact the inner plug. On an inner surface of the annular sidewall, an engaged portion vertically engageable with the engaging portion of the protrusion is formed.

Container closure for a container (1), the container closure having at least one receiving chamber, for receiving a substance of liquid or powdery consistency, and having a mouthpiece (5) comprising a through-opening (13), characterized in that the container closure has an adapter (2), into which a capsule (3) having the substance is interchangeably inserted, and an actuating element (6) for actuating the capsule (3), wherein the capsule (3) has a housing forming the receiving chamber, in which a perforator (7) is arranged, and the housing has two openings, wherein one opening is closed by a closure film (8) and the second opening is closed by an end region of the perforator (7), wherein the actuating element (6) is operatively connected to the end region of the perforator (7) that closes the second opening of the capsule (3), and the adapter (2), the capsule (3) and the actuating element (6) form mutually separate components.

A closure with an overcap and fitment is disclosed, wherein the overcap is removably attachable to the fitment, and wherein the fitment includes a spout and a removable inner portion that may be removed to allow contents to pass through the fitment.
