A removable container for powder or liquid includes a housing, a spilling mechanism and a bypass element. The housing hangs within a bottle and is capable of storing powder within the bottle while being sealed from a precursor liquid held within the bottle. The spilling mechanism enables the powder to spill out of the housing and into the precursor liquid and the bypass element provides the precursor liquid out of the bottle without mixing with the stored powder.

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 fastener device for closing a fluid reservoir (1) formed with a neck (10) provided with outer peripheral reinforcement (11) that co-operates with the remainder of the neck to define a bottom shoulder (12). The device includes a fastener ring (2) for holding a closure member (4) on the neck (10), the fastener ring (2) including a peripheral skirt (21) engaged around the neck to below the bottom shoulder (12). The skirt (21) has fastener elements (26a, 26b) that form a contact zones (27a, 27b) suitable for potentially engaging the neck (10) below the bottom shoulder (12). The contact zones (27a, 27b) are situated at different axial heights, such that some contact zones (27a; 27b) come into operating engagement below the bottom shoulder (12), while other contact zones (27a; 27b) remain inoperative.

An improved snap-on/twist off closure which is very durable. The invention is also directed to a package comprising the closure, e.g., a bottle in combination with the closure. The closure includes an upper wall defining an opening and a cylindrical snap on pipe depending from the upper wall. The pipe includes threads designed to mate with external threads on a neck of the bottle. The threads on the pipe and threads on the neck of the bottle pass over each other when the closure is snapped onto the bottle during manufacture. The pipe includes a resistance recess and a guidance recess. The resistance recess and the guidance recess accommodate a forcing element on a shoulder of the bottle and permit unscrewing of the closure

Disclosed is an integrated liquid injection evaporation container, including a container body provided therein with a space for storing a liquid; a seal gasket configured to seal the container body from an upper end portion is provided on an upper portion of the container body, where the seal gasket is an electric material; a press cap configured to press the seal gasket tight on the container body is further provided; a first injection hole configured to inject a fluid is provided on an upper end of the container body; a second injection hole corresponding to the first injection hole is provided on the press cap. Use of the first injection hole, the second injection hole, and the seal gasket achieves the objectives of convenient liquid injection without contamination, and simple mechanical liquid injection.

A closure element of the press-twist type for closing a container comprises: a capsule having a side wall extending about an axis, and a transverse panel extending transversely to said axis, an annular seal for sealingly engaging with a mouth of the container. The annular seal is made of a PVC-free material and comprises: a side portion arranged in contact with the side wall of the capsule; a front portion extending from the side portion towards said axis; a deformability promoting element for increasing deformability of the front portion, the deformability promoting element comprising a recessed zone configured to be at least partially filled by the material forming the front portion when the front portion is pressed against an edge of the container delimiting the mouth.
