A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged; a cover portion configured to be attachable to the discharge port member and to be capable of opening and closing the discharge port; and a sealing portion formed of a contact portion between the cover portion and the discharge port member. The cover portion includes a groove structure between an outer periphery of the cover portion and the sealing portion.

A liquid storage container includes: a discharge port member including a discharge port through which liquid stored in a storage portion is discharged and a coupling portion in which a male thread portion is arranged on the outside; and a cover portion including a female thread portion on the inside and configured to be attachable to the discharge port member, the female thread portion configured to be screwed to the male thread portion, in which the male thread portion is discontinuous in the coupling portion.

The invention relates to a protective cap for a dispenser, and to a dispenser for discharging pharmaceutical and/or cosmetical liquids, wherein the dispenser has a liquid reservoir and an outlet opening through which the liquid can be discharged into a surrounding atmosphere. The protective cap comprises an outer cap and an inner element inserted therein, wherein either at least one ventilation channel, which can be closed by means of a shut-off element and provides communication between an interior of the protective cap and an external environment, is formed between the outer cap and the inner element, or the inner element closes a ventilation opening of the outer cap.

The present disclosure relates to a pilferproof cap assembly(100) for a container(10). The assembly(100) is configured to facilitate refilling and decanting of fluid in the container(10). The assembly(100) comprises a neck housing(12) and an adaptor(40). The neck housing(14) is configured to be fitted on an opening of the container(10). The neck housing(12) is provided with a linearly displaceable diaphragm(24) to define a fluid-orifice(50) for fluid flow, and an air-orifice(30) to facilitate air flow. The adaptor(40) is configured to be mounted on an operative top of the neck housing(12) and is further configured to actuate the fluid-orifice(50) and the air-orifice(30) in an operative configuration of the assembly(100). The assembly thus facilitates the refilling and decanting of fluid therefrom in a pilferproof manner.
