Definitions

  • the present invention relates to a cosmetics container.
  • Patent Literature 1 Many techniques relating to a container for holding mascara have been proposed (for example, Patent Literature 1).
  • the gas existing between the outer container and the inner container also expands due to heating and may cause the connection established between the outer container and the inner container to become defective.
  • the present invention provides a cosmetics container in which an outer container and an inner container are securely connected.
  • a first invention is a cosmetics container, which is a cosmetics container having a container main body formed having an inner container inserted in the inside of an outer container; wherein on an outer surface of the inner container, a groove portion is formed having a length in the lengthwise direction of the inner container longer than a length in the direction orthogonal to the lengthwise direction; and the groove portion is configured so that when the inner container is inserted in the outer container, the groove portion passes through the outside of the container main body.
  • the groove portion formed on the outer surface of the inner container is configured to pass through the outside of the container main body, when the gas expands between the inner container and the outer container, it is discharged to the outside of the container main body. Therefore, even if the gas expands when the inner container and the outer container are connected, since the expanded gas is discharged to the outside through the groove portion, it is possible to securely connect the inner container and the outer container.
  • a second invention is the cosmetics container according to the configuration of the first invention, wherein the container main body is formed so that the distance between an inner surface of the outer container and an outer surface of the inner container becomes larger toward the bottom, and the length of the groove portion in the lengthwise direction is defined by the distance.
  • the groove portion is unnecessary. Meanwhile, when the distance is not sufficiently large, the groove portion is useful because the resistance for the gas to pass between the outer container and the inner container is large.
  • the length of the groove portion is defined by the distance between the inner surface of the outer container and the outer surface of the inner container, it is possible for the groove portion to be formed with a necessary and sufficient length.
  • a third invention is the cosmetics container according to the configuration of the second invention, wherein a width of the groove portion is configured so as to become larger toward the upper end of the inner container.
  • the outer container and the inner container are positioned at their respective upper ends. That is, at the upper ends of the outer container and the inner container, the inner surface of the outer container and the outer surface of the inner container are in contact with each other. Since the larger the distance between the inner surface of the outer container and the outer surface of the inner container, the smaller the resistance for gas to pass through, the width of the groove is sufficient even if it is narrow (even if it is small). Since the smaller the distance between the inner surface of the outer container and the outer surface of the inner container, the greater the resistance for gas to pass through, it is better that the width of the groove be wider (larger).
  • the resistance for gas to pass through increases toward the upper end of the inner container.
  • the width of the groove portion is configured to increase toward the upper end of the container, it is possible to take in the expanded gas into the groove portion and release to the outside even near the upper end of the container main body.
  • a fourth invention is the cosmetics container according to the configuration of the second invention, wherein the groove portion is configured of a first groove portion formed in a predetermined range near the upper end of the inner container and a second groove portion formed continuous to the first groove portion; the second groove portion extends to a predetermined position in the predetermined range and the width becomes larger toward the upper end of the inner container; and the width of the first groove portion is configured to be smaller than the largest width of the second groove portion.
  • the inner container and the outer container are positioned near the upper ends of the respective containers. Therefore, in order to reduce the resistance for gas to pass through in the vicinity of the upper end of the container, it is desirable that the width of the groove portion to be large, but from the viewpoint of positioning, the width of the groove portion is preferably small.
  • the groove portion functions not only as a passage through which the gas passes, but also as a buffer portion for holding the gas. In other words, since the expanded gas is retained in the groove portion, the expansion of the gas does not immediately affect the connection between the outer container and the inner container. Therefore, a large groove portion width does not necessarily need to be maintained up to the upper end.
  • the width of the groove portion is configured to increase toward the upper end in the second groove portion while the width of the first groove portion is configured to be smaller than the largest width of the second groove portion, the problem of the gas expansion impairing the connection between the outer container and the inner container is resolved while also fulfilling the request to minimize resistance for gas to pass through and the request to secure the positioning of the outer container and the inner container.
  • a fifth invention is the cosmetics container according to the configuration of any one of the first through fourth inventions, wherein the direction in which the groove portion extends has a directional component orthogonal to the lengthwise direction.
  • the expanded gas can be efficiently taken into the groove portion.
  • a sixth invention is the cosmetics container according to the configuration of any one of the first through fifth inventions, wherein the groove portion has a spiral portion formed in a spiral shape and a linear portion formed in a straight line connecting predetermined positions of the spiral portion.
  • the expanded gas can flow into the groove portion at any position in the direction orthogonal to the lengthwise direction, the expanded gas can be efficiently taken into the groove portion.
  • a seventh invention is the cosmetics container according to the configuration of any one of the first through sixth inventions, wherein the outer container and the inner container have a circular cross section in a direction orthogonal to the lengthwise direction; the inner container is made of resin; and the diameter of a predetermined range near the upper end of the outer peripheral surface of the inner container is formed to be a predetermined degree larger than the diameter of the inner peripheral surface of the outer container.
  • the diameter of the outer peripheral surface of the inner container is formed to be a predetermined degree larger than the diameter of the inner peripheral surface of the outer container. Therefore, when the inner container is inserted into the outer container, the resin inner container elastically deforms and shrinks. Then, when the insertion is completed, a force acts so that the inner container presses the outer container from the inside to the outside. As a result, the inner container is firmly connected to the outer container.
  • An eighth invention is the cosmetics container according to the configuration of any one of the first through seventh inventions, which has a cap formed by inserting an inner cap inside an outer cap; wherein on the outer surface of the inner cap, a cap groove portion is formed having a portion whose length in the lengthwise direction is longer than the length in the direction orthogonal to the lengthwise direction; and the cap groove portion is configured to pass through the outside of the cap when the inner cap is inserted into the outer cap.
  • the cap groove portion formed on the outer surface of the inner cap is configured to lead to the outside of the cap, when the inner cap and the outer cap are connected, any gas that may have expanded therebetween is discharged to the outside of the cap main body. Therefore, even if the gas expands when the inner cap and the outer cap are connected, since those effects are eliminated by the groove portion, it is possible to securely connect the inner cap and the outer cap.
  • a ninth invention is the cosmetics container according to the configuration of the eighth invention, wherein a space exists between the outer surface of the inner cap and the inner surface of the outer cap; a plurality of the cap groove portions are formed on the outer surface of the inner cap; of the plurality of cap groove portions, a portion of cap groove portions is configured to pass through the space and the outside of the cap; and the other cap groove portion is configured to pass through the space and not to the outside.
  • the inner cap and the outer cap are positioned with each other in the vicinity of their respective lower ends.
  • the lower ends of the inner cap and the outer cap serve as a boundary with the outside of the cap. For positioning, it is desirable that there is no cap groove portion at the lower end of the inner cap, but if there is no cap groove portion at all, the expanded gas cannot be released to the outside.
  • the cap groove portions since only a portion of the cap groove portions is configured to pass through both the space and the outside of the cap, it is possible to satisfy both the request for positioning and the request for discharge of expanded gas.
  • the cap groove portion that does not pass through to the outside is continuous with the cap groove portion that passes through to the outside through the space, it is possible for the expanded gas to be discharged.
