Abstract
A liquid-containing combination container includes a first container that contains a liquid, a second container that contains the first container and that has an oxygen barrier property, and an oxygen absorber that absorbs oxygen in the second container. The first container includes a container body that includes an opening portion and a stopper that closes the opening portion, the stopper has oxygen permeability.
Claims20
A liquid-containing combination container comprising:
- a first container that is a vial bottle including a glass container body that includes an opening portion and a stopper that closes the opening portion, the first container containing a liquid such that the stopper is separated from the liquid;
- a second container that contains the first container and that has an oxygen barrier property;
- and
- an oxygen absorber that absorbs oxygen in the second container,
- wherein the stopper contains silicone and has oxygen permeability, and
- wherein an oxygen permeation amount of a cutout portion of the container body is 1×10−1 (mL/(day×atm)) or more in an atmosphere at a temperature of 23° C. and a humidity of 40% RH, the cutout portion of the container body including the stopper and an around-portion around the stopper.
A container set comprising:
- a first container that is a vial bottle including a glass container body that includes an opening portion and a stopper that closes the opening portion, the first container containing a liquid such that the stopper is separated from the liquid,
- a second container that is capable of containing the first container and that has an oxygen barrier property;
- and
- an oxygen absorber that absorbs oxygen in the second container,
- wherein the stopper contains silicone and has oxygen permeability, and
- wherein an oxygen permeation amount of a cutout portion of the container body is 1×10−1 (mL/(day×atm)) or more in an atmosphere at a temperature of 23° C. and a humidity of 40% RH, the cutout portion of the container body including the stopper and an around-portion around the stopper.
A method of manufacturing a liquid-containing container, comprising:
- closing a second container that contains a first container;
- and
- adjusting an amount of oxygen in the first container,
- wherein the first container is a vial bottle including a glass container body that includes an opening portion and a stopper that closes the opening portion,
- wherein the first container contains a liquid and the stopper is separated from the liquid,
- wherein the stopper contains silicone and has oxygen permeability,
- wherein an oxygen permeation amount of a cutout portion of the container body is 1×10−1 (mL/(day×atm)) or more in an atmosphere at a temperature of 23° C. and a humidity of 40% RH, the cutout portion of the container body including the stopper and an around-portion around the stopper,
- wherein the second container has an oxygen barrier property, and
- wherein in the adjusting the amount of oxygen, oxygen in the second container is absorbed by an oxygen absorber, oxygen in the first container permeates the first container, and an oxygen concentration in the first container reduces.
