Abstract
Provided is an effective life indicator and a stopper including the same, and more particularly, to an effective life indicator and a stopper including the same that are capable of allowing a consumer to easily check a drinkable or usable period after opening a beverage or medicine accommodated in a container by maintaining a state in which a development material receiving section is ruptured by a pressure applied to the container when the stopper is coupled to the container and starting an operation as a development material is leaked to the outside to come in contact with a development medium member when the stopper is initially separated from the container.
Claims16
An effective life indicator configured to display a drinkable or usable time period after opening, the effective life indicator comprising:
- a development material receiving section configured to accommodate a development material;
- a development medium member configured to absorb and diffuse the development material;
- a rupture member configured to leak the development material to the outside when the rupture member ruptures the development material receiving section and is separated therefrom;
- and
- a housing configured to accommodate the development material receiving section, the development medium member, and the rupture member therein and attached to an inner side of a stopper of a container,
- wherein the rupture member ruptures the development material receiving section using a pressure applied by the container when the stopper is coupled to the container, and the development material is leaked to the outside and comes in contact with the development medium member to start an operation thereof when the stopper is initially separated from the container.
A stopper of a container comprising an effective life indicator, the effective life indicator comprising:
- a development material receiving section configured to accommodate a development material;
- a development medium member configured to absorb and diffuse the development material;
- a rupture member configured to leak the development material to the outside when the rupture member ruptures the development material receiving section and is separated therefrom;
- and
- a housing configured to accommodate the development material receiving section, the development medium member, and the rupture member therein and attached to an inner side of the stopper of the container,
- wherein the rupture member ruptures the development material receiving section using a pressure applied by the container when the stopper is coupled to the container, and the development material is leaked to the outside and comes in contact with the development medium member to start an operation thereof when the stopper is initially separated from the container, and
- the stopper comprises one or more display units configured to allow recognition of one or more of starting and termination of an operation of the effective life indicator.
