Convenience of an ink bottle and a bottle set is improved. An ink bottle includes: a container portion that contains ink; a guiding portion that is formed in one end portion of the container portion, and includes an outflow port from which the ink in the container portion flow out; and a cover that covers at least an end portion of the container portion on the opposite side of the guiding portion.

A cap for a bottle, which comprises at least a sealing portion and a lateral portion for fastening to the bottle. The sealing portion comprises, along a direction substantially perpendicular to the lateral portion, a first region formed of unfoamed polymeric material, a second region formed of foamed polymeric material, and a third region formed of unfoamed polymeric material, the second region being positioned between the first region and the third region. The disclosure also relates to a process for manufacturing a cap made of foamed polymeric material.

The invention relates to a closure device (1) for a container (2) comprising a container opening (3), wherein the closure device (1) comprises a lid element (4) for closing the container opening (3), an inner housing (5) and a chamber (6) arranged on the lid element (4), wherein the chamber (6) is arranged at least partially in the inner housing (5), wherein the inner housing (5) has a first thread (10) which corresponds positively to a thread (10) of the container (2), wherein lid element (4) and inner housing (5) have second threads (11) corresponding positively to one another along which the lid element (4) is movable relative to the inner housing (5) from a closed position into a discharge position in which discharge position a medium stored in the chamber (6) can exit into the container (2). For the usage-advantageous further development of a closure device of the type in question, it is proposed that the first thread (10) and the second thread (11) are configured opposite to one another in such a manner that during a movement into the discharge position the chamber (6) is moved further into the inner housing (5).

An assembly of a closure with a container, for sealing of the container, comprises the container having an inner container surface defining a cavity opening to ambient through an opening, the closure comprising an upper portion and a lower portion, the lower portion having a lower lateral surface, the lower portion being adapted to be inserted into the opening of the container and two grooves provided on the lower lateral surface and adapted to receive two respective sealing members, the two grooves being separated by a predetermined distance, the two sealing members provided in the two respective grooves, the two sealing members being adapted to provide sealing between the lower lateral surface and the inner container surface, wherein the lower lateral surface, the inner container surface and the two auxiliary sealing members together define an annular space and a barrier sealant in the annular space.

An anti-spurt device, for application in a closure of a container with a cap and a ring with teeth for cutting a sealing membrane. The anti-spurt device may comprise a tube that automatically unfolds from a folded position and may be connected with the cutting ring. In the folded or loaded position, the tube may be outside of the sealing membrane and with the breakage of the membrane, it may be inserted and automatically unfolded in the inside of the container. In a second main embodiment, the need for a cutting ring and membrane may be eliminated, and the tube may be installed on a carriage held by a hook that is released with the opening of the cap.

An ink bottle includes: a container portion that contains ink; a guiding portion that is formed in one end portion of the container portion, and includes an outflow port from which the ink in the container portion flow out; and a cover that covers at least an end portion of the container portion on the opposite side of the guiding portion.

Drink containers include a liquid container and a cap assembly removably coupled to the liquid container. Cap assemblies include a switch, a trigger and seal bar. Upon actuating the trigger the seal bar slides back to form a drink outlet opening in the cap assembly. To hold the seal bar in an open state without additional external force from the user, the switch is slid from an unlocked position to a locked position, thereby keeping the drink outlet and a vent formed in the cap assembly open in order to cool down a warm beverage in the liquid container.

A spray gun and a detachable liquid reservoir releasably attached to the spray gun by engagement of mateable, non-threaded formations provided on the spray gun and the reservoir. The spray gun has an integral connector boss with a socket for reception of a connector tube of the reservoir. The boss has an external flange at the distal end and the reservoir has hook members separate from the connector tube. The hook members are co-operable with the flange when the connector tube is received in the socket to secure releasably the reservoir to the spray gun. In another arrangement, the connector tube is an interference friction-fit in the socket to secure releasably the reservoir to the spray gun. In yet another arrangement, the connector tube has bayonet lugs co-operable with bayonet grooves in the wall of the socket when the connector tube is received in the socket to secure releasably the reservoir to the spray gun. In a still further arrangement, the reservoir has an integral spout received in the socket integral with the spray gun and provided with a helical projection co-operable with the underside of a radial lug externally of the socket to secure the reservoir.

A package for pourable food products and method for moulding a polymeric opening portion to a packaging sheet material is provided. The package can include an opening portion and a weakening feature. In some embodiments, the opening portion can be made of a polymer composition. In some embodiments, the weakening feature has a thickness below 200 micrometers and is thinner than parts of the opening portion directly adjacent to said weakening feature. The polymer composition can include sodium sulphite particles. In some embodiments, the sodium sulphite particles have the following size characteristics: (i) 0% having a size above 75 micrometers, and (ii) an average size below 25 micrometers.
