Abstract

A cosmetic container having a detachable structure according to an aspect of the present disclosure includes a lower case in which contents are accommodated, an upper case for opening and closing the lower case, and a connection block that is shaft-coupled to the upper case and detachably coupled to the lower case by magnetic force.

Description

    BACKGROUND 1. Field
  • One aspect of the present disclosure relates to a cosmetic container having a detachable structure for an upper case, and more particularly, to a cosmetic container having a detachable structure for an upper case, in which the upper case is naturally fastened to or released from a lower case by magnetic force so that replacement of the lower case and convenience of use can be improved.
    • 2. Description of Related Art
  • According to the trend of the modern society that has diversified rapidly, persons use cosmetics as needed regardless of sex and age. In particular, in the case of women, makeup is done using a variety of cosmetics, makeup products having various colors and makeup tools.
  • In general, makeup is largely classified into basic makeup, color (cosmetic) makeup, hair makeup, and body makeup, in which the color makeup has the purpose of decorating more beautifully after the basic makeup is finished, so the color makeup is considered as a practical makeup that is performed by taking into account aesthetic, color, and fashionable senses.
  • Various types of color cosmetics are used for the above-described color makeup, and the color cosmetics are largely classified into skin expression cosmetics such as makeup base, foundation, and powder, eye cosmetics such as eye shadow, eye liner, eyebrow, and mascara. lip cosmetics such as lipstick, lip gloss, and lip cream, and cheek-touch cosmetics and the color cosmetics are manufactured in liquid or gel form, or solid or powder form and stored and used in cosmetic containers of various shapes depending on the characteristics thereof.
  • Accordingly, it has become necessary to develop containers for various types of cosmetics depending on the purpose of use and characteristics of the cosmetics. In general, liquid or gel cosmetics are filled in a glass container or tube container and used in a way that the user puts the cosmetics on the hand or squeeze the cosmetics to apply the cosmetics onto the skin.
  • However, such a conventional cosmetic container has a problem in that it is inconvenient to use the cosmetic container and the cosmetic material is wasted because the user has to put the cosmetics on the hands and then wash the hands whenever the user uses the cosmetics.
  • In order to solve the above problems, a compact container with a built-in puff has been developed so that it is not necessary to get a cosmetic material on the hand and it is easy to carry.
  • Such conventional compact containers are disclosed in Korean Utility Model Registration No. 20-0157472 and Korean Utility Model Registration No. 20-0458647. These related arts include a cosmetic dish in which the cosmetic is stored, a lower case in which the cosmetic dish is stored, an upper case for opening and closing the lower case, and a cosmetic puff accommodated in the upper and lower cases.
  • However, since the conventional compact container has no structure in which the cosmetic dish for storing the cosmetic is separated from the lower case, it is impossible to separately refill and use the cosmetic dish when the cosmetic material is completely exhausted. Thus, there was a problem that resources are wasted and the economic burden is increased on users because the users need to repurchase the compact container.
  • Korean Patent Registration No. 10-1584512 discloses a compact container for solving such a problem. The conventional compact container includes an outer container, a refill container coupled to the inside of the outer container to receive cosmetic materials therein, a refill upper container that opens and closes the refill container, and an upper outer container that opens and closes the outer container, in which the outer container and the refill container are undercut-coupled such that the outer container and the refill container can be attached to and detached from each other. When the cosmetic material contained in the refill container is used up, the refill container can be separated from the outer container, and a new refill container can be coupled to the outer container.
  • However, the conventional compact container has a structure in which the inner container storing the cosmetics is forcibly separated from the outer container by pushing the bottom portion of the inner container exposed to the outside in order to replace the inner container from the outer container. As a result, it is difficult for a woman having relatively weak strength to separate the refill container from the outer container. In addition, when the inner container is pressed excessively by a hand, noise is generated when the inner container is separated from the outer container, and the inner container suddenly jumps up and flies away, which is inconvenient in replacement and use.

  • As described above, the lower case 10 may be assembled by combining the case body 20 with the content case 30, and the rim plate 36 of the content case 30 may cover an upper portion of the block insertion groove 26 of the case body 20, so that the connection block 50 inserted into the connection block insertion groove 26 may be released downward of the case body 20 without being released upward of the case body 20. That is, as shown in the partially enlarged view of FIG. 2, the connection block insertion groove 26 has a configuration in which lower and outer portions thereof are open, an upper portion thereof is closed, and the open outer portion has a width relatively narrower than that of an inner portion thereof.
  • The upper case 40 may open or close the content case 30 of the lower case 10 while rotating at a predetermined angle.
  • As shown in FIG. 3, a mirror 42 may be formed on the inner surface of the upper case 40 so that the user can make up while illuminating the makeup area, and a second locking projection 44 may be formed on the inner circumference of the upper case 40 so as to be engaged with the first locking protrusion 24 a of the case body 20.
  • In addition, a shaft coupling portion 46 may extend downward from the location opposite to the second locking protrusion 44 so as to be shaft-coupled to the connection block 50. The shaft coupling portion 46 may include an extension portion 46 a extending vertically from an end of the upper case 40 and a coupling portion 46 b that is formed on an end of the extension portion 46 a and shaft-coupled to the connection block 50, in which an inner surface of the extension portion 46 a may be inserted into the first upper case insertion groove 36 b of the content case 30 and a second upper case insertion groove 57 of the connection block 50, and the coupling portion 46 b may be inserted into a shaft insertion hole 52 of the connection block 50.
  • As shown in FIG. 1, the upper case 40 may be opened while rotating 180 degrees or more from the lower case 10. In the cosmetic container according to an aspect of the present disclosure, the upper case 40 and the lower case 10 may be shaft-coupled through the connection block 50, in which the shaft coupling portion 46 extending downward of the upper case 40 may be rotate in a state in which it is inserted into the shaft insertion hole 52 of the connection block 50, thus, unlike the conventional existing open structure, the upper case 40 may be horizontally opened while being completely turned over without interfering with the lower case 10.
  • The connection block 50 may be configured to connect the lower case 10 and the upper case 40, and may be shaft-coupled to the upper case 40 and detachably coupled to the lower case 10 by magnetic force. In this case, the connection block 50 may be connected to the inner side of the shaft coupling portion 46 of the upper case 40, and slidably inserted into a lower portion of the connection block insertion groove 26 of the lower case 10.
  • As shown in FIG. 2, the shaft insertion hole 52 may be formed in the lower center of the connection block 50 so that the end of the shaft coupling portion 46 of the upper case 40 may be inserted into the shaft insertion hole 52. In this case, a hinge pin crossing the shaft insertion hole 52 may be coupled to the inner portion of the shaft insertion hole 52, and preferably, the shaft coupling portion 46 may be hinge-coupled by the hinge pin. The shaft insertion hole 52 may provide a shaft coupling space between the upper case 40 and the connection block 50 as well as a shaft rotation space for the shaft coupling portion 46. Accordingly, the shaft coupling portion 46 of the upper case 40 may rotate naturally from the lower case 10 without being caught by other parts. Preferably, a portion of one surface of the connection block 50, which is exposed to the outside of the lower case 10, is curved in accordance with the surface curvature of the lower case 10 for the beauty or luxury of appearance of the cosmetic container and the continuity of the design.
  • In addition, an insertion groove 54 may be formed inside the center of the connection block 50, and a second fastening portion 58 may be inserted into the insertion groove 54. The insertion groove 54 may be formed adjacent to the rim plate 36 of the content case 30, and one surface of the insertion groove 54 adjacent to the rim plate 36 may be opened. This is to allow the magnetic force to effectively act between the first fastening portion 38 formed in the lower case 10 and the second fastening portion 58 formed in the connection block 50. In this case, preferably, the second fastening portion 58 may be formed of a magnet to attract the first fastening portion 38 by magnetic force. In the cosmetic container according to an aspect of the present disclosure, the first fastening portion 38 is described as a metal plate, and the second fastening portion 58 is described as a magnet, but the disclosure is not limited thereto. The first fastening portion 38 and the second fastening portion 58 may be interchanged, or both the first fastening portion 38 and the second fastening portion 58 may be formed of magnets.
  • Meanwhile, separation prevention protrusions 56 may protrude from both sides of the connection block 50 so as to be engaged with the separation prevention grooves 26 a of the lower case 10. That is, the connection block 50 may be slidably inserted into the lower portion of the connection block insertion groove 26 of the lower case 10, and at the same time, the separation prevention protrusions 56 of the connection block 50 may be inserted into the connection block insertion groove 26 of the lower case 10. Through the above dove-tail structure (which is a fitting type of the slide surface and refers to a structure in which a protrusion like a pigeon tail is engaged with a corresponding groove), the connection block 50 may slide only vertically without being released to the lateral side of the lower case 10. Accordingly, in a state in which the shaft coupling portion 46 of the upper case 40 and the connection block 50 are connected in a straight line, the connection block 50 may be separated from or fastened to the lower case 10 by pulling downward or pushing upward the connection block 50. In this case, both surfaces of the connection block 50 and the surface of the separation prevention protrusion 56 may serve as sliding surfaces that make contact with the connection block insertion groove 26 of the lower case 10.
  • In addition, the second upper case insertion groove 57 may be formed on one surface of the connection block 50, which is exposed to the outside of the lower case 10, so that the inner surface of the shaft coupling portion 46 of the upper case 40 may be inserted into the second upper case insertion groove 57.
  • As described above, in the cosmetic container according to an aspect of the present disclosure, the upper case 40 is rotatably shaft-coupled to the connection block 50, and the connection block 50 is coupled to the lower case 10 such that the connection block 50 can be naturally fastened to or separated from the lower case 10 by magnetic force, thereby facilitating the replacement of the lower case 10 and improving the convenience of use. In addition, the connection block 50 can be slidably inserted from the bottom of the lower case 10 and fitted with the lower case 10 in a dove-tail structure, so that the upper case 40, which is shaft-coupled to the connection block 50, can stably rotate without be rattled or shaken and cannot be easily separated from the lower case 10 when opened or closed.
  • FIGS. 4 to 7 are views illustrating use and replacement of a cosmetic container according to an aspect of the present disclosure, and a method of using and replacing the cosmetic container according to an aspect of the present disclosure will be described with reference to the drawings.

  • In order to use the cosmetic container according to an aspect of the present disclosure, as shown in FIG. 4, the button 24 exposed to one side of the lower case 10 is pressed to release the connection between the lower case 10 and the upper case 40. After that, the upper case 40 is rotated to be opened, the content case cover 60 is rotated to open the content case 30, and the cosmetic contents accommodated in the content case 30 are applied to the skin by taking the cosmetic contents using a cosmetic tool such as a puff P. After the makeup is finished, in the reverse sequence to the above, the content case cover 60 is closed, the upper case 40 is rotated to be closed, and the upper case 40 and the lower case 10 are fastened to be stored or carried.
  • Meanwhile, when all the cosmetic contents contained in the lower case 10 are used, the lower case 10 may be replaced for use.
  • As shown in FIG. 5, when all the cosmetic contents contained in the lower case 10 are exhausted, the upper case 40 is rotated from the lower case 10 so as to be opened. In this case, the upper case 40 is opened while being rotated by 180 degrees or more, so that, unlike the conventional open structure, the upper case 40 is completely turned over and positioned horizontally at the lower portion of the lower case 10, and the shaft coupling portion 46 of the upper case 40 and the connection block 50 are aligned in a straight line.
  • Thereafter, as shown in FIG. 6, the connection block 50, which is shaft-coupled to the upper case 40, is pulled downward so that the connection block 50 is separated from the lower case 10. In this case, the lower case 10 and the connection block 50, which are fastened by the magnetic force of the first fastening portion 38 and the second fastening portion 58, are separated from each other by pulling force of the user, and continuously, the connection block 50 slides in the connection block insertion groove 26 of the lower case 10 to come out of the connection block insertion groove 26.
  • Then, as shown in FIG. 7, the upper case 40 separated from the lower case 10 is slidably inserted into the connection block insertion groove 26 of a new lower case 10. In this case, the separation prevention protrusions 56 of the connection block 50 are fitted into the separation prevention grooves 26 a of the lower case 10, so that the upper case 40 can stably rotate without being rattled or shaken when opened or closed and the connection block 50 can be prevented from being separated from the case body 20.
