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.
- a tenth invention is the cosmetics container according to the configuration of the eighth or ninth invention, wherein the width of the cap groove portion which is configured to pass through the outside of the cap is configured to become narrow at a predetermined position near the lower end of the groove portion.
- the configuration of the tenth invention it is possible to satisfy both the function of positioning the vicinity of the lower end portion of the inner cap with the outer cap and the function of discharging the gas to the outside.

Abstract
The cosmetics container of the present invention has a container main body formed by inserting the inner container inside the outer container, wherein a groove portion is formed in the outer surface of the inner container with a length in the lengthwise direction of the inner container longer than the length in the direction orthogonal to the longitudinal direction, and the groove portion is configured to pass through to the outside of the container main body when the inner container is inserted into the outer container.
Description
- The present invention relates to a cosmetics container.
- In the manufacturing process of a cosmetics container, it is important to securely connect its parts to each other.
- Many techniques relating to a container for holding mascara have been proposed (for example, Patent Literature 1).
- In Patent Document 1, mascara is held in a bottle 2. Meanwhile, when a cosmetics container formed by arranging an inner container for holding mascara inside an outer container (hereinafter referred to as “double container”) is adopted, the outer container and the inner container need to be securely connected. For connecting the outer container and the inner container, for example, a thermoplastic resin is used as a connecting material. In this case, the melted thermoplastic resin is placed between the outer container and the inner container; however, there are times where the gas existing between the outer container and the inner container expands making it difficult to connect the outer container and the inner container. Further, even if the outer container and the inner container are successfully connected at one point to begin with, in the subsequent sterilization process, 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.
- Based on the above, 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.
- According to the configuration of the first invention, since 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.
- When the distance between the inner surface of the outer container and the outer surface of the inner container is sufficiently large, since the resistance for gas to pass between the outer container and the inner container is small, 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. In this regard, according to the configuration of the second invention, since 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.
- In a cosmetics 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). Since the distance between the inner surface of the outer container and the outer surface of the inner container is configured to increase toward the bottom, the resistance for gas to pass through increases toward the upper end of the inner container. In this regard, according to the configuration of the third invention, since 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.
- In a container in which the inner container is inserted into the outer container, 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. Here, 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. In this respect, according to the configuration of the fourth invention, since 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.
- According to the configuration of the fifth invention, since the position where the expanded gas can flow into the groove portion increases in the direction 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.
- According to the configuration of the sixth invention, since 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.
- According to the configuration of the seventh invention, 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.
- According to the configuration of the eighth invention, since 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.
- Having all the groove portions pass through both the space and the outside of the cap is desirable from the viewpoint that the resistance for gas to pass through is small. Meanwhile, with the cap in which the inner cap is inserted into the outer cap, 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. In this regard, according to the configuration of the ninth invention, 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. Here, since 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.
- A tenth invention is the cosmetics container according to the configuration of the eighth or ninth invention, wherein the width of the cap groove portion which is configured to pass through the outside of the cap is configured to become narrow at a predetermined position near the lower end of the groove portion.
- According to the configuration of the tenth invention, it is possible to satisfy both the function of positioning the vicinity of the lower end portion of the inner cap with the outer cap and the function of discharging the gas to the outside.
- According to the present invention, it is possible to provide a cosmetics container in which an outer container and an inner container are securely connected.

The cosmetics container 1 is an example of a cosmetics container, theouter container 10 is an example of an outer container, and theouter cap 30 is an example of an outer cap. In the present specification, the lengthwise direction of the cosmetics container 1 is referred to as the “lengthwise direction”. The lengthwise direction is the direction indicated by the arrow Z1 inFIG. 1 . The direction orthogonal to the lengthwise direction is referred to as the “orthogonal direction”. The orthogonal direction is the direction indicated by the arrow X1 inFIG. 1 . - An inner container 20 (see
FIG. 7 and others) is inserted inside theouter container 10 to form a container main body. An inner cap 40 (seeFIG. 18 and others) is inserted inside anouter cap 30 to form a cap (lid). Theinner container 20 is an example of an inner container, and theinner cap 40 is an example of an inner cap. - As illustrated in
FIG. 4 , when theouter cap 30 is removed from the cosmetics container 1, theinner container 20 becomes visible. As described above, theinner cap 40 is inserted inside theouter cap 30. Ahandle 42 is connected to theinner cap 40, and abrush 44 is connected to thehandle 42. Liquid cosmetics are held in theinner container 20. Liquid cosmetics are, for example, mascara. - The cosmetics container 1 is formed in a size that can be grasped and used by a user. For example, the length L1 of the cosmetics container 1 in the lengthwise direction (see
FIG. 1 ) is 119.5 millimeters (mm), and the maximum width LW1 in the orthogonal direction is 16.59 mm. The length L2 of theouter container 10 is 78 mm, and the length L3 of theouter cap 30 is 41.3 mm. - The

Theinner container 20 is configured of amain body portion 22 and a connectingportion 24. Male threading 24 a is formed on the connectingportion 24 so as to engage with ascrew 44 d (seeFIG. 19 ) of aninner cap 40. - The
main body portion 22 is configured of abase portion 22 a and anenlarged diameter portion 22 b. The outer surface of thebase portion 22 a is referred to as an outerperipheral surface 22 a 1, and the outer surface of theenlarged diameter portion 22 b is referred to as an outerperipheral surface 22 b 1. Agroove portion 22 c is formed across the outerperipheral surface 22 a 1 and the outerperipheral surface 22 b 1. Thegroove portion 22 c has a length in the lengthwise direction longer than the length in the orthogonal direction. Thegroove portion 22 c passes through ashoulder surface 24 b of the connectingportion 24. When theinner container 20 is inserted into theouter container 10 and connected to form the container main body, thegroove portion 22 c is connected to the outside of the container main body. That is, thegroove portion 22 c is open on theshoulder surface 24 b. - As illustrated in
FIG. 8 , the outer circumference of theenlarged diameter portion 22 b is formed to have a diameter d2. The diameter d2 is a predetermined degree larger than the diameter d1 of the upper end portion of the innerperipheral surface 10 b of theouter container 10. The predetermined degree is defined in a predetermined numerical range. For example, with respect to the diameter d1, the diameter d2 is larger in the numerical range of 0.2% or more and 0.7% or less. For example, the diameter d1 is 14.8 mm and the diameter d2 is 14.85 mm. - The
base portion 22 a is formed in the lengthwise direction as a curved surface having a curvature radius R2. The curvature radius R2 is smaller than the curvature radius R1 of theouter container 10 by a predetermined degree. The predetermined degree is specified in a predetermined numerical range. For example, with reference to the curvature radius R1, the curvature radius R2 is smaller in the numerical range of 0.03% or more and 0.08 or less. For example, the curvature radius R1 is 938 mm and the curvature radius R2 is 937.55 mm. - The
groove portion 22 c is configured of afirst groove portion 22 c 1 and asecond groove portion 22 c 2. Thefirst groove portion 22 c 1 and thesecond groove portion 22 c 2 are formed as a continuous integrated groove. More specifically, the recess of theenlarged diameter portion 22 b formed by thefirst groove portion 22 c 1 with respect to the outerperipheral surface 22 b 1 and the recess of the outerperipheral surface 22 b 1 and thebase portion 22 a formed by thesecond groove portion 22 c 2 with respect to the outerperipheral surface 22 a 1 are continuous and integrated. - As illustrated in
FIG. 9 , a plurality ofgroove portions 22 c (first groove portion 22 c 1 andsecond groove portion 22 c 2) are formed on the outerperipheral surface 22 a 1 of thebase portion 22 a and the outerperipheral surface 22 b 1 of theenlarged diameter portion 22 b. Specifically, fourgroove portions 22 c are formed on the outerperipheral surfaces 22 a 1 and 22 b 1 with a deviation of 90 degrees. - As illustrated in
FIGS. 10 to 13 , thefirst groove portion 22 c 1 is formed in a predetermined range near the upper end of theinner container 20.FIG. 10 is an enlarged view of thegroove portion 22 c viewed from above, andFIG. 11 is an enlarged view of thegroove portion 22 c viewed from below. In the present specification, “near the upper end” of theinner container 20 means theenlarged diameter portion 22 b. Thefirst groove portion 22 c 1 is formed in a predetermined range including the upper end of theenlarged diameter portion 22 b in the lengthwise direction. The predetermined range is, for example, aportion 22 b 1 a ofFIGS. 12 and 13 . Thefirst groove portion 22 c 1 passes through theshoulder surface 24 b. That is, thefirst groove portion 22 c 1 is open on theshoulder surface 24 b. - The
second groove portion 22 c 2 is formed continuously with thefirst groove portion 22 c 1. Thesecond groove portion 22 c 2 extends from thebase portion 22 a to a position within a predetermined range of theenlarged diameter portion 22 b. The predetermined range of theenlarged diameter portion 22 b is, for example, theportion 22 b 1 b ofFIGS. 12 and 13 . The width of thesecond groove portion 22 c 2 is formed so as to increase toward the upper end of theinner container 20. - As illustrated in
FIG. 12 , thefirst groove portion 22 c 1 is formed to have a width w1. With thesecond groove portion 22 c 2, the largest width is formed as the width w2. The width w1 is smaller than the width w2. - As illustrated in
FIG. 13 , thefirst groove portion 22 c 1 is formed with a depth e1. Thesecond groove portion 22 c 2 is formed with a depth e2 in theportion 22 b 1 b and is formed with a depth e3 in thebase portion 22 a. The depth e1 is shallower than the depth e3, and the depth e3 is shallower than the depth e2. That is, the expression of “e1<e3<e2” (Expression 1) is satisfied. - The relationship between the outer
peripheral surfaces 22 a 1 and 22 b 1 of theinner container 20 and the innerperipheral surface 10 b of theouter container 10 when theinner container 20 is inserted into theouter container 10 to form the container main body will be described while referencingFIG. 14 . The outerperipheral surface 22 a 1 is divided into outerperipheral surfaces 22 a 1 to 22 a 3 in accordance with the height from the upper end portion, and the bottom portion is designated as thebottom portion 22 a 4. Similarly, the innerperipheral surface 10 b is divided into innerperipheral surfaces 10 b 0 to 10 b 3 according to the height from the upper end portion, and the bottom portion is designated as thebottom portion 10 b 4. - The
inner container 20 and theouter container 10 are positioned with the outerperipheral surface 22 b 1 in contact with the innerperipheral surface 10 b 0. Thefirst groove portion 22 c 1 is formed on the outerperipheral surface 22 b 1. Thesecond groove portion 22 c 2 is formed over the outerperipheral surface 22 b 1 and the outerperipheral surfaces 22 a 1 and 22 a 2. Thegroove portion 22 c is formed with a length L4. - The distance between the outer

As illustrated inFIG. 15 , in the lengthwise direction, the innerperipheral surface 10 b of theouter container 10 is formed as a curved surface having a curvature radius R1, and the outerperipheral surface 22 a 1 of theinner container 20 is formed as a curved surface having a curvature radius R2. As described above, the curvature radius R2 is smaller than the curvature radius R1. Therefore, when theinner container 20 is inserted into theouter container 10, as illustrated inFIG. 16 , the upper end portions come into contact with each other, and the distance between the outerperipheral surface 22 a 1 and the innerperipheral surface 10 b increases toward the bottom. - The length L4 of the
groove portion 22 c is defined by the distance between the outerperipheral surface 22 a 1 and the innerperipheral surface 10 b. That is, when theinner container 20 is inserted into theouter container 10, since gas can pass through without experiencing significant resistance when a sufficient gap exists between the outerperipheral surface 22 a 1 and the innerperipheral surface 10 b, thegroove portion 22 c is not formed. Meanwhile, with a position where there is no sufficient gap between the outerperipheral surface 22 a 1 and the innerperipheral surface 10 b, thegroove portion 22 c is formed since significant resistance is experienced when the gas passes through or the gas is not able to pass through. Since there is a sufficient gap between the outerperipheral surface 22 a 3 and the innerperipheral surface 10 b 3 described above, thegroove portion 22 c is not formed. Meanwhile, since the gap is insufficient between the outerperipheral surface 22 a 1 and the innerperipheral surface 10 b, thegroove portion 22 c is formed. - As described above, when the
inner container 20 is connected to theouter container 10 to form the container main body, the distance between the outerperipheral surface 22 a 1 and the innerperipheral surface 10 b is smallest at the upper end thereof. In this respect, in the present embodiment, the expanded gas can be taken in by forming the width of thesecond groove portion 22 c 2 larger toward the upper end. - As illustrated in
FIG. 17 , anouter cap 30 is a lid having an open lower end. A cross section of theouter cap 30 in the orthogonal direction is formed in a circular shape. With theouter cap 30, the outer surface is referred to as an outerperipheral surface 30 a, and the inner surface is referred to as an innerperipheral surface 30 b. Theouter cap 30 is formed in a shape where the diameter increases from the lower end portion toward the top, and the upper end portion and the upper end vicinity portion are formed as a spherical surface. - As illustrated in
FIGS. 18 and 19 , aninner cap 40 has amain body portion 44 and ahandle 42 connected to themain body portion 44. Thelower end portion 44 c of theinner cap 40 is open. Ascrew 44 d is formed on the inner surface of themain body portion 44. Although the brush 44 (seeFIG. 4 ) is connected to the lower end portion of thehandle 42, thebrush 44 is omitted in the following description. - As illustrated in
FIG. 18 , acap groove portion 44 a 1 is formed on the outerperipheral surface 44 a of theinner cap 40. Thecap groove portion 44 a 1 is a groove whose length in the lengthwise direction is longer than the length in the orthogonal direction. A plurality ofcap groove portions 44 a 1 are formed, and among thecap groove portions 44 a 1, a portion of thecap groove portions 44 a 1 is continuous with the secondcap groove portion 44 a 2. Hereinafter, thecap groove portion 44 a 1 continuous with the secondcap groove portion 44 a 2 will be referred to as a “continuous cap groove portion”. When theinner cap 40 is inserted into theouter cap 30 to form the cap, the secondcap groove portion 44 a 2 is configured to lead to the outside of the cap. The width of the secondcap groove portion 44 a 2 is smaller than the width of thecap groove portion 44 a 1. - When the
inner cap 40 is inserted into theouter cap 30 to form a cap, a space exists between the outer surface of theinner cap 40 and the inner surface of theouter cap 30. As illustrated inFIG. 20 , a space S1 exists between theupper end portion 44 b of theinner cap 40 and theceiling surface 30 b 1 of theouter cap 30. The continuous cap groove portion is configured to pass through both the space S1 and the outside of the lower portion of the cap. Thecap groove portion 44 a 1 that does not form the continuous cap groove portion is configured so as to pass through the space S1 and not to the outside of the cap. - Next, the connection between the
inner container 20 and theouter container 10 will be described with reference toFIGS. 21 and 22 . First, as illustrated inFIG. 21 , the connectingresin 100 is applied to the outerperipheral surface 22 a 1 of theinner container 20. The melting point of theresin 100 is equal to or lower than the melting point of the resin forming theinner container 20. Theresin 100 is applied in a molten state. The surrounding gas expands due to the heat radiated from themolten resin 100. - Next, as illustrated in
FIG. 22 , theinner container 20 is inserted into theouter container 10. Theresin 100 spreads between the outerperipheral surface 22 a 1 of theinner container 20 and the innerperipheral surface 10 b of theouter container 10, fills the space between the outerperipheral surface 22 a 1 and the innerperipheral surface 10 b, and functions as a connecting means. As described above, since the diameter d2 of theenlarged diameter portion 22 b of theinner container 20 is larger than the diameter d1 of the upper end portion of the innerperipheral surface 10 b of theouter container 10, when theinner container 20 is inserted into theouter container 10, theenlarged diameter portion 22 b is elastically deformed and reduced, and when the insertion is completed, the innerperipheral surface 10 b of theouter container 10 is pressed from the inside. In this way, theinner container 20 is fixed inside theouter container 10. In this state, a space S2 exists between thebottom surface 10 b 4 of theinner surface 10 b of theouter container 10 and thebottom surface 22 a 4 of the outer surface of theinner container 20. - When the
inner container 20 is inserted into theouter container 10, since theresin 100 is in a molten state and radiates heat, the gas between theinner container 20 and theouter container 10 expands. When the cosmetics container 1 is manufactured under atmospheric air, the gas is air. As illustrated inFIG. 23 , the expanded gas flows into thegroove portion 22 c as indicated by arrows A1 and A2 and is discharged from between theinner container 20 and theouter container 10 as indicated by arrow A3. - Therefore, the expanded gas does not interfere with the connection between the
inner container 20 and theouter container 10. Further, even when theinner container 20 and theouter container 10 are connected and the mascara is stored inside theinner container 20 and heated for sterilization or the like, the gas existing between theouter container 10 and theinner containers 20, for example, the gas existing in the space S2 and the like, expands. However, it also flows into thegroove portion 22 c and does not affect the connection state between theouter container 10 and theinner container 20. The gas flow indicated by arrows A1 to A3 inFIG. 23 indicates the gas flow between theinner container 20 and theouter container 10; however, description of theouter container 10 is omitted inFIG. 23 . - Next, a state in which the
inner cap 40 is connected to theouter cap 30 will be described. When theinner cap 40 is inserted into theouter cap 30, themolten resin 100 is applied to the outerperipheral surface 44 a of theinner cap 40 similar to the above-mentionedinner container 20. Through this, although the gas between theinner cap 40 and theouter cap 30 expands, as illustrated inFIG. 24 , with the continuous cap groove portion, it flows into thecap groove portion 44 a 1, passes through the secondcap groove portion 44 a 2, and is released to the outside as indicated by the arrow B3. The gas that has flowed into thecap groove portions 44 a 1 other than the continuous cap groove portion flows into the space S1 as indicated by arrows B1 and B2, then flows into the continuous cap groove portion, and is also released to the outside. - Therefore, the expanded gas does not interfere with the connection between the
inner cap 40 and theouter cap 30. Further, when theinner cap 40 and theouter cap 30 are connected and heated for sterilization or the like, the gas existing between theouter cap 30 and theinner cap 40 expands, but thecap groove portion 44 a 1 also expands. Since it flows into the gas and is discharged to the outside through the continuous cap groove portion, it does not affect the connection state of theouter cap 30 and theinner cap 40. The gas flow indicated by arrows B1 to B3 inFIG. 24 indicates the gas flow between theinner cap 40 and theouter cap 30; however, the description of theouter cap 30 is omitted inFIG. 24 . - Next, the assembly process of the cosmetics container 1 will be described with reference to
FIGS. 25 and 26 . In addition, inFIG. 25 andFIG. 26 , members located inside other members are also indicated by solid lines. As illustrated inFIG. 25 , in a state where theinner container 20 is inserted into theouter container 10 and fixed, agate member 26 is connected to a connectingportion 24 of theinner container 20. Thegate member 26 has a circular cross section in the orthogonal direction. When using the cosmetics container 1, thegate member 26 comes into contact with thebrush 44 and adjusts the amount of mascara attached to thebrush 44. As illustrated inFIG. 26 , theinner cap 40 connected to theouter cap 30 engages with theinner container 20 connected to theouter container 10 to form the cosmetics container 1. - A second embodiment will be described with reference to
FIGS. 27 to 30 . Matters common to the first embodiment will be omitted, and portions different from the first embodiment will be mainly described. - As illustrated in
FIGS. 27 to 29 , with aninner container 20A of the second embodiment, a groove portion 22Ac is formed over abase portion 22 a and anenlarged diameter portion 22 b. The groove portion 22Ac becomes wider toward the upper end portion of theinner container 20A. That is, the groove portion 22Ac has the largest width at the opening in theshoulder surface 24 b. - As illustrated in
FIG. 30 , in theinner cap 40A, all thecap groove portions 44 a 1 are connected to the secondcap groove portion 44 a 2 to form a continuous cap groove portion. - A third embodiment will be described with reference to
FIG. 31 . Matters common to the first embodiment will be omitted, and portions different from the first embodiment will be mainly described. - With an
inner container 20B of the third embodiment, of a plurality ofsecond groove portions 22 c 2, a portion of thesecond groove portion 22 c 2 is continuous with afirst groove portion 22 c 1. For example, as illustrated inFIG. 31 , of the foursecond groove portions 22 c 2, only onesecond groove portion 22 c 2 is continuous with thefirst groove portion 22 c 1 to form a continuous groove portion. Gas that has flowed into thesecond groove portions 22 c 2 that do not form a continuous groove portion flows into the continuous groove portion through a space between theinner container 20B and theouter container 10 such as the space S2 (seeFIG. 22 ) and is discharged to the outside. - A fourth embodiment will be described with reference to
FIG. 32 . Matters common to the first embodiment will be omitted, and portions different from the first embodiment will be mainly described. - With an inner container 20C of the fourth embodiment, the direction in which a
second groove portion 22 c 3 extends has a component in the orthogonal direction in addition to the component in the lengthwise direction. For example, as illustrated inFIG. 32 , thesecond groove portion 22 c 3 is formed in a meandering manner. As a result, expanded gas can be quickly taken into thesecond groove portion 22 c 3 and discharged to the outside. - A fifth embodiment will be described with reference to
FIG. 33 . Matters common to the first embodiment will be omitted, and portions different from the first embodiment will be mainly described. - With an
inner container 20D of the fifth embodiment, the direction in which asecond groove portion 22 c 4 extends has a component in the orthogonal direction in addition to the component in the lengthwise direction. Specifically, thesecond groove portion 22 c 4 is configured of aspiral portion 22 c 41 formed in a spiral shape on the outerperipheral surface 22 a 1 of thebase portion 22 a and a plurality ofstraight portions 22c 42 connecting the portions of thespiral portion 22 c 41 in the orthogonal direction. As a result, expanded gas can be quickly taken into thesecond groove portion 22 c 4 and discharged to the outside. - The cosmetics container of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention.
