Description

    Technical Field
  • The present invention relates to a mixing type container that is designed to mix two types of contents stored therein, more specifically to a mixing type container that is capable of allowing a second container to be coupled to a first container so that as the second container rotates, the second container communicates with the first container to allow the content stored in the second container to communicate with the content stored in the first container, thereby mixing the contents.
    • Background Art
  • Generally, high-priced functional cosmetics exert excellent effectiveness when two different types of contents stored therein are mixedly used, but such functional contents are very unstable in properties. In this case, if a functional content is pre-mixed with a base content, the functional content may become acid and deteriorated. Therefore, the two contents are stored in a state of being separated from each other, and just before the corresponding cosmetic is used, it is desirable that they have to be mixed.
  • To do this, a product with the two contents packed in individual containers is sold, and if the product is desired to be used, the two contents are mixed with each other by a user. In the case of such a conventional product, however, the two contents are stored in the respective storage containers and carried with the user, thereby causing many inconveniences of use.
  • To solve such problems, new containers are developed to mix two contents by removing a blocking plate, while separately storing two different types of powders or solutions in a single container, if it is desired to use the powders or solutions.
  • In the case of such conventional mixing type containers, however, a structure in which the two types of contents are perfectly separated from each other may be complicated, thereby making it hard to achieve precise molding in manufacturing the containers, and further, sealing of the contents is not kept well, thereby causing a high possibility of defects in keeping and distributing products. Furthermore, the conventional containers may become bulky in volume so as to receive the two types of contents therein, and a process for filling the single container with the two types of contents may be very complicatedly carried out. In the case of most of the conventional mixing type containers, besides, a second container may be received in a first container or covered with a given structure so that a second content is not recognized at all at the outside.
    • Disclosure Technical Problem
  • Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the related art, and it is an object of the present invention to provide a mixing type container that is capable of mixing two types of contents in a simple configuration and in an easy method.
  • The technical problems to be achieved through the present invention are not limited as mentioned above, and other technical problems not mentioned herein will be obviously understood by one of ordinary skill in the art through the following description.
    • Technical Solution
  • According to an embodiment of the present invention, a mixing type container may include: a first container in which a first content is stored; and a second container in which a second content is stored, wherein the second container is coupled to one end of the first container, and one region of the second container rotates to allow another region of the second container to become inserted into the first container so that the second container communicates with the first container.
    • Advantageous Effects of Invention
  • According to embodiments of the present invention, the mixing type container is configured to allow two types of contents to be mixed together by means of simple rotation.
  • According to the present invention, further, the mixing type container is configured to allow the container storing the second content to be inserted into the first container if it is desired to mix the first content and the second content together, thereby ensuring the efficient space for receiving the second content and reducing the volume of the second container, after mixing, to thus enhance space utilization.
  • According to the present invention, furthermore, the mixing type container is configured to allow the second container to be sealed separately from the first container and then distributed, thereby preventing the second content from being deteriorated or contaminated and ensuring efficient distribution and production process.
  • According to the present invention, besides, the mixing type container is configured to allow the first container and the second container to be filled efficiently with two types of contents in a simple method, thereby enhancing production efficiency.
  • According to the present invention, moreover, the mixing type container is configured to allow the first container and the second container to be made of a transparent material so that the first content and the second content are seen on the outside and their mixing process is visually checked by a user, thereby causing lots of excitement and fun on the outer appearance thereof.
  • The effectiveness of the invention is not limited as mentioned above, and it should be understood to those skilled in the art that the effectiveness of the invention may include another effectiveness as not mentioned above from the detailed description of the present invention.

  • Referring to FIGs. 1 and 2, a mixing type container according to an embodiment of the present invention largely includes a first container 100 and a second container 200. According to the embodiment of the present invention, the first container 100 is a container in which a first content is stored and has a top 100a coupled to a cap 110 with a discharge member. For example, the first container 100 is a general bottle, but without being limited thereto, it may be freely changed in shape. For example, the first content is a liquid or gel cosmetic. According to one embodiment of the present invention, the cap 110 is provided with the discharge member such as a dropper, a pipet, a pump, and the like and replaceable with a part such as a sealing cover, and the like.
  • According to one embodiment of the present invention, the content that can be stored in the container may include cosmetics, a cream, a lotion, a skin cleaner, a shampoo, a conditioner, and a hair dye.
  • According to one embodiment of the present invention, the second container 200 is a container in which a second content is stored and detachable from the other end 100b of the first container 100, e.g., from the underside of the first container 100. According to one embodiment of the present invention, the second container 200 has the shape of a general cylinder, but without being limited thereto, it may have various shapes.
  • The second content stored in the second container 200 is different in formulation, color, ingredients, and shape from the first content. For example, the second content has the same ingredients as the first content, but it has a different color from the first content. The first content is an essence, but the second content is vitamin. The first content and the second content are desirably liquid formulations, and their types and shapes may be freely applied.
  • According to one embodiment of the present invention, the mixing type container is configured to allow the second container 200 to be coupled to the first container 100. In detail, the second container 200 is rotatably coupled to the first container 100.
  • According to one embodiment of the present invention, if the second container 200 is coupled to the first container 100, an outer cover 211 of the second container 200 is located under the first container 100. The outer cover 211 is coupled to the first container 100 to form a portion of the outer shape of the mixing type container.
  • According to one embodiment of the present invention, further, a storage container 231 storing a second content may be exposed to the outside from one end of the outer cover 211 (e.g., from the underside of the First container 100). For example, the exposed direction of the storage container 231 is opposite to the coupling direction of the second container 200.
  • According to one embodiment of the present invention, the second container 200 has a stopper 251 for sealing the second content. According to one embodiment of the present invention, if the stopper 251 is coupled to the second container 200, the second container 200 is sealed from the outside, and if the stopper 251 is separated from the second container 200, the second container 200 becomes in a state of being refillable with the second content, without being sealed from the outside.
  • According to one embodiment of the present invention, at least one region of the first container 100 and/or second container 200 is made of a transparent material. In this case, the formulations or colors of the contents stored in the first container 100 and the second container 200 can be checked immediately, and further, the process of mixing the first content and the second content can be visually checked, thereby causing lots of excitement and fun on the outer appearance of the mixing type container. If the storage container 231 in which the second content is stored is exposed to the outside from the outer cover 211, the storage container 231 is made of the transparent material to allow the second content to be checked on the outside by means of the exposed portion thereof.
  • FIG. 3 is a sectional view showing a process in which the first and second contents are mixed together by means of the rotation of a given region of the second container according to the embodiment of the present invention.
  • Referring to FIG. 3, if one region (e.g., the outer cover 211) of the second container 200 to rotate after the second container 200 has been coupled to the first container 100, another region (e.g., the storage container 231 in which the second content is stored) of the second container 200 is inserted into the first container 100 to allow the first container 100 and the second container 200 to communicate with each other, thereby mixing the first content of the first container 100 and the second content of the second container 200 together.
  • According to one embodiment of the present invention, in a process where one region of the second container 200 is inserted into the first container 100, a strong rising pressure that is generated by the movement of the second content is transferred to allow a path adapted to allow the first content and the second content to communicate with each other to be open, so that the first content and the second content are mixed together. Hereinafter, the respective components of the mixing type container will be explained in detail.
  • FIG. 4 is an exploded perspective view showing the second container of the mixing type container according to the embodiment of the present invention. FIG. 5 is a sectional view showing a state in which the second container is coupled to the first container according to the embodiment of the present invention.
  • Referring to FIGs. 4 and 5, according to one embodiment of the present invention, the second container 200 includes the outer cover 211, a guide 212, a guide cap 213, a first moving part 230, a second moving part 250, and an elastic body 240.
  • According to one embodiment of the present invention, the outer cover 211 is rotatably coupled to one end (particularly, the underside) of the first container 100. The outer cover 211 induces the first moving part 230 to move and guides the moving direction of the first moving part 230. According to one embodiment of the present invention, the first moving part 230 rotates together with the outer cover 211 if the outer cover 211 rotates, and further, the first moving part 230 is inserted into the first container 100 by a first distance by means of the guide of the outer cover 211. According to one embodiment of the present invention, the second moving part 250 moves to the inside of the first container 100 by a second distance by means of the movement of the first moving part 230 in such a way as to allow the second content to communicate with the first content.
  • The outer cover 211 is a portion of the outer shape of the first container 100 and serves as a handle so that it is grasped and then rotates. For example, after the outer cover 211 is grasped by a user, it rotates to a given angle. If the outer cover 211 rotates, the first moving part 230 is released from being locked and thus becomes movable vertically.
  • The outer cover 211 has at least one or more guide grooves 2111 on the inner peripheral surface thereof in such a way as to guide the movement of the first moving part 230 (in detail, guide protrusions 233 as will be discussed later). If the outer cover 211 rotates, the first moving part 230 rotates together with the outer cover 211 in a state where the guide protrusions 233 of the first moving part 230 are inserted into the guide grooves 2111.
  • According to one embodiment of the present invention, the rotation angle of the outer cover 211 is limited to a range between 0 and 90°.
  • According to one embodiment of the present invention, the guide 212 is a member that guides the first moving part 230 (in detail, a storage container cap 232 as will be discussed later) to move and is coupled to the outer cover 211. The guide 212 has at least one or more first openings 2121 on the outer peripheral surface thereof. For example, the first openings 2121 are linear. According to one embodiment of the present invention, the first openings 2121 insert the guide protrusions 233 of the storage container cap 232 thereinto and thus guide the guide protrusions 233 to move.
  • According to one embodiment of the present invention, the at least one or more guide grooves 2111 of the outer cover 211 are located to face the at least one or more first openings 2121 of the guide 212. According to one embodiment of the present invention, while the outer cover 211 is rotating, if the at least one or more guide grooves 2111 of the outer cover 211 are located to face the at least one or more first openings 2121 of the guide 212, the guide protrusions 233 move linearly along the guide grooves 2111 and the first openings 2121.
  • In detail, the guide protrusions 233 are inserted into the guide grooves 2111 of the outer cover 211 and rotate together with the outer cover 211, and in this case, the guide protrusions 233 are limited (in locked states) in vertical movements by means of the underside of the outer peripheral wall of the guide 212.
  • While the outer cover 211 is rotating, if the at least one or more guide grooves 2111 of the outer cover 211 are located to face the at least one or more first openings 2121 of the guide 212, the guide protrusions 233 are inserted into the first openings 2121 and move linearly along the guide grooves 2111 and the first openings 2121. That is, the guide protrusions 233 are released from the locked states to allow the first moving part 230 to move linearly.
  • The outer cover 211 rotates only to a point at which the first moving part 230 is released from being locked and does not rotate anymore to an angle over the point. If the guide protrusions 233 are inserted into the first openings 2121 during the rotation of the outer cover 211, the rotation of the outer cover 211 is stopped.
  • According to one embodiment of the present invention, the guide 212 has locking projections 2126 for restricting the rotating directions of the guide protrusions 233. The locking projections 2126 protrude downward from the underside of the outer peripheral wall of the guide 212. The locking projections 2126 serve to restrict the movements of the guide protrusions 233 to the opposite direction to one direction so that the guide protrusions 233 rotate in one direction and are thus inserted into the first openings 2121.
  • According to one embodiment of the present invention, the guide 212 is hollow so that it has a second opening 2122 on the central portion thereof. According to one embodiment of the present invention, the second opening 2122 is a space in which the stopper 251 and a piston rod 252 constituting the second moving part 250 are inserted thereinto.
  • According to one embodiment of the present invention, the guide 212 has the shape of a general ring and consists of an outer peripheral wall 2124, an inner peripheral wall 2125, and a ring-shaped space portion 2123. According to one embodiment of the present invention, the outer peripheral wall 2124 surrounds the inner peripheral wall 2125, and the ring-shaped space portion 2123 is located between the outer peripheral wall 2124 and the inner peripheral wall 2125. According to one embodiment of the present invention, at least a portion of the first moving part 230 is inserted into the ring-shaped space portion 2123. In this case, the volume of the container becomes reduced, upon the mixing of the contents, to advantageously ensure the efficient utilization of space. In the case of the conventional container for mixing two types of materials, a large space is needed to store them, respectively, and even after they have been mixed together, the volume of the container is still kept. Contrarily, in the case of the mixing type container of the present invention, the first moving part 230 is inserted into the inner space of the guide 212, thereby achieving efficient space utilization and allowing the volume of the container to become reduced after the contents have been mixed.
  • According to one embodiment of the present invention, the guide cap 213 is coupled to the inside of the guide 212. A coupling structure between the guide cap 213 and the guide 212 may be freely provided, for example, by means of grooves and protrusions. It is possible that the guide cap 213 and the guide 212 are formed integrally with each other. According to one embodiment of the present invention, the guide cap 213 is hollow so that it has an open space at the central portion thereof in such a way as to pass the second moving part 250 therethrough. According to one embodiment of the present invention, the guide cap 213 has a first seating portion 2131 for supporting one end of the elastic body 240. According to one embodiment of the present invention, at least a portion of the guide cap 213 serves as a stopper for restricting the movement of the second moving part 250.
  • According to one embodiment of the present invention, the first moving part 230 serves to store the second content and linearly moves (e.g., is inserted into) to the first container 100. The first moving part 230 is inserted into the first container 100 by the first distance by means of the rotation of the outer cover 211.
  • According to one embodiment of the present invention, the first moving part 230 consists of the storage container 231 and the storage container cap 232. The storage container 231 stores the second content. According to one embodiment of the present invention, at least one region of the storage container 231 is exposed to the outside from the outer cover 211, and if the storage container 231 is made of a transparent material, as a result, the second content can be seen on the outside.
  • According to one embodiment of the present invention, the storage container cap 232 is coupled to the storage container 231 and has the at least one or more guide protrusions 233 on the outer peripheral surface thereof in such a way as to be inserted into the first openings 2121 and thus move linearly. According to one embodiment of the present invention, the storage container cap 232 has a second seating portion 234 on at least a portion, for example, on one end thereof in such a way as to support the other end of the elastic body 240. According to one embodiment of the present invention, the storage container cap 232 has a third opening 235 on the central portion thereof in such a way as to insert the second moving part 250 thereinto.
  • According to one embodiment of the present invention, the elastic body 240 provides a primary force for moving the first moving part 230 and a secondary force for moving the second moving part 250, and the elastic body 240 is, for example, a compression coil spring.
  • According to one embodiment of the present invention, the elastic body 240 is located between the guide 212 and the first moving part 230 to provide the force for moving the first moving part 230 by the first distance. In detail, one end of the elastic body 240 is supported against the first seating portion 2131 of the guide cap 213, and the other end thereof against the second seating portion 234 of the storage container cap 232.
