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.

The present invention is related to a cap assembly which is put over a mouth of a bottle and a method for capping of capping the cap assembly to a bottle, and includes a function that makes it possible to open an inner stopper only by operating a cap when removing the cap initially, and makes attaching thereof to the bottle easy. There are included an inner stopper 40 and a cap 50, which respectively include a male screw thread 411c and a female screw thread 541, and the inner stopper 40 and the cap 50 while a state in which they are assembled is maintained are capped to a bottle 60, and when the cap 50 is removed initially, the cap 50 is firstly rotated in a direction of closing to have a junction section 52 broken, and then the cap 50 is rotated in a direction of opening so that the lid body 42 of the inner stopper 40 is removed together with cap 50, thereby causing the inner stopper 40 also to be in a state of being opened.

A dispensing closure (40, 40A, 40B) includes a first body (54, 54A, 54B) for being located at an opening of a container (44, 44A, 44B) and having a first peripheral wall (56, 56A, 56B) and a membrane (60, 60A, 60B) that is integrally molded with the first peripheral wall (56, 56A, 56N) to initially occlude access to the interior of the container (44, 44A, 44B). The closure (40, 40A, 40B) includes a second body (55, 55A, 55B) for surrounding at least a portion of the first body (54, 55A, 55B) and defining a dispensing orifice (88, 88A, 88B). Either the first body (54, 54A, 54B) and/or the second body (55, 55A, 55B) includes means for accommodating engagement by a user to breach only a portion of the membrane (60, 60A, 60B) in a direction toward the interior of the container (44, 44A, 44B) to permit access to the interior of the container (44, 44A, 44B).

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 food package container may have an integrated spout that can be used to dispense the contents of the container into a consumer's mouth. In some examples, the food package container includes an elongated, flexible-wall container body providing a tubular chamber holding a foodstuff. The container has a spout formed by a narrowing of the container body in a region extending upwardly away from the tubular chamber. For example, spout may be bound on one side by the container body and further bound on an opposite side and on a top edge by a seal joining opposed walls of the container body together. To open the spout, a weakened line may extend laterally across the container body adjacent the top edge of the spout and longitudinally across the container body adjacent the side of the spout bound by the seal.

There is described a spout for a package having a designated pour opening and being filled with a pourable product. The spout comprises at least a collar extending along a longitudinal axis, carrying a pouring outlet at a first axial end and an inlet opening for the pourable product at a second axial end and delimiting a flow channel for the pourable product extending between the pouring outlet and the inlet opening a closing element configured to interrupt a fluidic connection between the pouring outlet and the inlet opening. The closing element is interposed between the inlet opening and the pouring outlet and is rupturably fixed to an inner surface of the collar.

A package-sealing device that includes a sealing element provided with an outlet, the walls of the outlet being in contact with each other, making it close. The package-sealing device includes a closing element, and the sealing element is made up of a flexible sheet, said sealing element being partially attached to the closing element, such that the sealing element deforms when the closing element is removed, thus defining an outlet and closing it when the walls of the outlet are in contact with each other.

A food containment and dispensing system includes a collapsible pouch forming a cavity to contain a food product. A spout fitment is coupled to the collapsible pouch and includes a spout that extends from the collapsible pouch. A spout thread extends radially from the spout. The spout thread starts at a spout rib, which defines a spout rib contact surface. A cap is in threaded engagement with the spout, and it includes a cylindrical wall. A cap thread extends radially from the cylindrical wall and terminates at a cap rib, which defines a cap rib contact surface that is in contact with the spout rib contact surface to prevent further rotation of the cap with respect to the spout.

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 structural element for a bottle closure having means for showing a first use in nominal conditions. This structural element can be made from components such as a pouring dispenser or a frame. This structural element is characterized by the use of two components which are linked such that the attachment between both disappears after the first use in nominal conditions when said structural element is mounted in the operating mode on the bottle. The first use in nominal conditions requires removing one of the components and it cannot be put back in its original position, restoring its also original attachment.
