Description

  The present invention relates to a container that can prevent oxidation of a liquid such as a beverage, and an antioxidant member.

  Conventionally, a technique of adding an antioxidant to a liquid in order to prevent oxidation of the liquid such as a beverage is known (see Patent Document 1).

JP 2001-200250 A

  However, in the method described in Patent Document 1, since the liquid itself contains an antioxidant, there has been a problem that the characteristics of the liquid (taste and flavor in the case of a beverage) are greatly changed. This invention is made | formed in view of the above point, and it aims at providing the container and antioxidant member which can prevent the oxidation of a liquid, without changing the characteristic of a liquid largely.

The container of the present invention is a container that can store a liquid and has a portion containing a silicate mineral.
The container of the present invention can prevent the oxidation of the liquid by lowering the redox potential of the contained liquid by the silicate mineral. It can be inferred that the cause of this effect is the terahertz wave generated by the silicate mineral.

Examples of the container of the present invention include a container having a layer containing a silicate mineral inside or outside the container.
The layer containing a silicate mineral may be a layer made of only a silicate mineral, or may be a layer made of a silicate mineral and another component (for example, a binder). As the binder, known ones can be used as appropriate. Moreover, you may use a glaze as a binder. For the layer containing silicate mineral, for example, a slurry containing a silicate mineral powder and a binder is applied to the inside or outside of the container body (the part of the container excluding the layer containing the silicate mineral). Can be formed. As a coating method, a known method can be appropriately selected. For example, a spraying method, a dipping method, a method using a brush or a roller, or the like can be used. After applying the slurry, firing can be performed to increase the strength and adhesion of the layer.

The average particle diameter of the silicate mineral powder contained in the slurry is, for example, preferably in the range of 0.1 to 1000 μm, particularly preferably in the range of 1 to 100 μm.
The layer containing the silicate mineral may be in direct contact with the liquid contained in the container, or another member (for example, another layer) may exist between the layer and the liquid.

  In the container of the present invention, the portion excluding the layer containing silicate mineral can be formed of various materials. For example, ceramics (including ceramics), resin (eg, silicon resin, PP, PE, etc.), wood, metal, rubber, etc. can be used.

  In the container of the present invention, the layer containing the silicate mineral may be formed on the entire inner surface of the container, or only a part of the inner side (for example, only the bottom, only the side, only a part of the side, etc.) It may be formed. In the container of the present invention, the layer containing the silicate mineral may be formed on the entire outer surface of the container, or only a part of the outer side (for example, only the bottom, only the side surface, only a part of the side surface). Etc.).

  Examples of the container of the present invention include a container containing a silicate mineral inside a wall constituting the container. In this case, for example, a container can be manufactured by configuring the container shape with a mixed material containing a silicate mineral powder and a base material. As the base material, for example, ceramics (including ceramics), resin (for example, silicon resin, PP, PE, etc.), metal, rubber or the like can be used.

  Examples of the container according to the present invention include a container having a first chamber for storing a liquid and a second chamber for storing a silicate mineral. The first room and the second room may be completely separated by a partition wall or may be communicated with each other. Examples of the arrangement of the first room and the second room include the following.

  (i) The container has a double structure of an outer container and an inner container accommodated therein. The inside of the inner container is the first room, and the space between the inner container and the outer container is the second room. Further, the first room and the second room may be reversed.

  (ii) The inside of the container is partitioned into a plurality of (for example, 2, 3, 4, 5,...) small rooms by a partition wall. A part of the plurality of small rooms (one or plural) may be a first room, and a part or all of the other small rooms may be a second room.

The antioxidant member of the present invention contains a silicate mineral and is used for liquid antioxidant applications.
The antioxidant member of the present invention can reduce the oxidation-reduction potential of the liquid and prevent oxidation of the liquid by the silicate mineral. It can be inferred that the cause of this effect is the terahertz wave generated by the silicate mineral.

  Examples of the antioxidant member of the present invention include those provided with a silicate mineral (for example, silicate mineral powder) and a film surrounding the periphery thereof. As this film, for example, a film made of resin, paper, rubber, metal or the like can be used.

  Examples of the antioxidant member of the present invention include a member including a base material and a silicate mineral (for example, a silicate mineral powder) dispersed in the base material. As the base material, for example, ceramics (including ceramics), resin (for example, silicon resin, PP, PE, etc.), metal, rubber, or the like can be used. The base material is preferably porous.

  The antioxidant member of the present invention can be used, for example, in contact with a liquid (for example, by immersing the whole or a part of the antioxidant member in the liquid). In this case, the antioxidant member can be attached to a container that stores the liquid so that the liquid stored in the container is in contact with a part or all of the antioxidant member. For example, the container may be a bottle-shaped container having a lid, the antioxidant member is attached to the lid, and the antioxidant member enters the inside of the container when the lid is closed.

Moreover, the antioxidant member of the present invention can be used as a pipe or a filter, for example, by passing a liquid through the pipe or filter.
Moreover, the antioxidant member of the invention can be used by being disposed in the vicinity of the liquid in a non-contact state with the liquid, for example.
