Description

A container for contents that can be separated from an outer container by rotation of a decorative member

[0001] The present invention relates to a contents container, and more particularly, to a contents container in which the contents are separated from the outer container by rotation of a decorative member.

[0002] Recently, many new refill structures have been developed that allow the contents to be separated from the outer container and replaced when the contents are exhausted.

[0003] Existing refillable containers require complex fastening structures to separate the inner and outer containers for adding new contents or replacing the outer container. This can make refilling difficult for users. Furthermore, these complex fastening structures complicate the manufacturing process and increase the number of parts. This hinders efficient use and can pose environmental concerns.

[0004] Furthermore, to facilitate separation and connection between the outer and inner containers, the inner container must be manufactured to match the shape of the outer container, placing significant constraints on the shape of the inner container. These limitations limit the product diversity of existing refill containers.

[0005] Therefore, there is a need for research and development of a new refill structure that is convenient for refilling and can be applied to various types of products without restrictions on the shape of the contents.

[0006] The present invention is intended to solve the above problem, and its purpose is to provide a contents container that can separate the contents from the outer container simply by rotating a decorative member.

[0007] The technical problems of the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0008] According to an embodiment of the present invention, a contents container is provided. The contents container includes an outer container; an inner container configured to accommodate contents and be accommodated in the outer container; and a decorative member configured to be detachably coupled to the inner container so as to couple the inner container to the outer container and supported by the outer container; wherein the inner container is configured to be detachable from the outer container based on rotation of the decorative member relative to the outer container.

[0009] According to the present invention, the inner container can be separated from the outer container simply by rotating the decorative member, making the process of replacing and refilling the contents very simple and easy. Furthermore, the simple fastening structure for refilling offers the advantage of increasing manufacturing process and cost efficiency.

[0010] Furthermore, the present invention can be attached and detached from an outer container without limitation on the shape of the inner container, making it applicable to various types of containers. This increases product diversity and allows for product differentiation by flexibly adapting to product shape and use.

[0032]

[0033] Fig. 1 is a perspective view of a contents container (1) according to an embodiment of the present invention. Fig. 2 is an exploded view of a contents container (1) according to an embodiment of the present invention. In particular, Fig. 2 includes an enlarged view of a decorative member (300) described from a different angle and an enlarged view of an outer container neck (420) of an outer container (400).

[0034] Referring to FIGS. 1 and 2, the contents container (1) may include a cap (100), a pump device (200), a decorative member (300), an outer container (400), and / or an inner container (500).

[0035] In one embodiment, a pump device (200), a decorative member (300), an outer container (400), and an inner container (500) may form a container assembly (200, 300, 400, 500). The container assembly (200, 300, 400, 500) may store contents therein and discharge the contents to the outside. More specifically, contents may be accommodated in the inner container (500), and a pump device (200) may be formed on one side of the container assembly (200, 300, 400, 500) to communicate with the interior of the inner container (500) in order to discharge the contents. The pump device (200) may be shielded or exposed to the outside depending on the position of the cap (100), and may be configured to discharge contents to the outside of the container assembly (200, 300, 400, 500) depending on the user's pressure (pumping action) on the pump head (210). At this time, the contents may be cosmetics, medicines, over-the-counter drugs such as toothpaste, etc., but may include all types of substances that can be discharged by the pumping action.

[0036] As described above, the container (500) may be configured to accommodate contents. More specifically, the container (500) may include a container body (510) in which a space is formed to accommodate contents, and a container neck (520) extending from the container body (510). As illustrated in FIG. 2, the container neck (520) may have a smaller cross-sectional area than the container body (510). The container neck (520) may have an opening formed on one side to accommodate contents in the container body (510) or to accommodate at least a portion of the pump device (200). For example, as illustrated in FIG. 2, the opening may be formed on the upper side of the container neck (520). The lower portion of the container body (510) may cover the space in which the contents are accommodated to prevent the contents (500) from being discharged outside the container (500).

[0037] In one embodiment, the contents container (500) may further include a disk (not shown) that is positioned inside a space provided to receive contents and moves upwards as the contents are discharged. The disk pushes the contents upwards as the contents stored in the space are exhausted, and specifically, the disk maintains a state of close contact with the inner wall of the space, and may rise in response to a decrease in the volume of the contents within the space as the contents are discharged. A contents container (1) of this type may be referred to as an airless type. An airless type contents container (1) may be characterized by not having a separate tube for sucking the contents into the pump device (200). Meanwhile, embodiments of the present invention are not limited to the airless type, and are still applied to a type in which a tube is formed in the pump device (200).

[0038] In one embodiment, the content member (500) can be formed in various shapes without limitation, such as circular, square, oval, cylindrical, square column, and conical.

[0039] The outer container (400) may be configured to accommodate the inner container (500). That is, the inner container (500) may be configured to be accommodated inside the outer container (400). The outer container (400) may have a shape corresponding to the inner container (500). For example, as illustrated in the drawing, the inner container (500) may have a substantially cylindrical shape, and the outer container (400) may have a cylindrical shape corresponding thereto. The outer container (400) may include an outer container body (410) corresponding to the inner container body (510) and an outer container neck (420) corresponding to the inner container neck (520). That is, the outer container neck (420) may extend from the outer container body (410). The outer container neck (420) may be formed to have a smaller cross-sectional area than the outer container body (410). The outer container neck (420) may have an opening formed on one side to allow at least a portion of the pump device (200) to be inserted. An opening may be formed to allow the inner container (500) to be inserted into an end of the outer container body (410) where the outer container neck (420) is not positioned. In other words, the lower side of the outer container body (410) may be open. For example, an opening may be formed on the upper side of the outer container neck (420) and the lower side of the outer container body (410). Accordingly, the outer container (400) may be formed to be connected in the vertical direction. If only the outer container (400) and the inner container (500) are provided, the outer container (400) cannot support the inner container (500), so a separate configuration as described below is required to prevent the inner container (500) from being separated from the outer container (400) even if the inner container (500) is accommodated in the outer container (400).

[0040] The decorative member (300) may be provided to surround the outer container neck (420). The decorative member (300) may enhance the aesthetic appeal of the outer container neck (420). Furthermore, the decorative member (300) may protect the outer container neck (420). For example, as illustrated in FIG. 2, the decorative member (300) may have a donut shape with a hole formed substantially in the center, following the shape of the outer container neck (420). The decorative member (300) may be supported by the outer container (400), or may be supported by the pump member and / or the inner container (500) described below. Furthermore, the decorative member (300) may be combined with the inner container (500) described above. Accordingly, the decorative member (300) is combined with the inner container (500), and the decorative member (300) is directly or indirectly supported by the outer container (400), thereby substantially preventing the inner container (500) and the outer container (400) from being separated. This will be described in more detail in the description with reference to FIG. 3.

[0041] As described above, the pump device (200) may be configured to discharge the contents contained in the container (500) to the outside of the container (1). The pump device (200) may include a cylinder (280) positioned on the side facing the space where the contents of the container (500) are contained. When the pump head (210) of the pump device (200) is pressurized, the piston rod (260) (FIG. 3) positioned inside may move to cause the contents to move toward the pump head (210). The pump device (200) may be supported by the container (500) or by a decorative member (300). At this time, the pump device (200) is coupled to the upper side of the container (500) and may discharge the contents stored in the space to the outside by pressurization.

[0042] The above configuration is described in more detail below.

[0043] FIG. 3 is a cross-sectional view of a contents container (1) according to an embodiment of the present invention. In particular, FIG. 3 (a) illustrates that a contents container (500) is coupled to an outer container (400) of the contents container (1). FIG. 3 (b) illustrates that the contents container (500) is separated from the outer container (400) of the contents container (1).

[0044] Referring to Fig. 3, the configuration of the contents container (1) is described in more detail.

[0045] The pump device (200) may include an outwardly protruding pump head (210), a stem (230) coupled with the pump head (210) to support the pump head (210), and / or an undercap (240) supporting the stem (230). Furthermore, the pump device (200) may include a piston rod (260) accommodated in the stem (230) and / or a cylinder (280) accommodated with one end of the piston rod (260). The piston rod (260) may be supported by a container (500). The pump device (200) may include a ring portion (250) positioned between the piston rod (260) and the container neck (520).

[0046] For example, as illustrated in FIG. 3, a stem (230) may be positioned at the lower side of a pump head (210), and an under cap (240) may support the lower side of the stem (230). The under cap (240) may be supported by a cylinder (280) positioned at the lower side of the under cap (240). The cylinder (280) may include an annular rib extending radially outward, and the rib included in the cylinder (280) may be supported from the lower side by the inner body neck (520). That is, the pump device (200) may be supported by the inner body. Furthermore, a support flange (332) described later may cover the annular rib included in the cylinder (280).

[0047] The pump device (200) may include an elastic member (220) that applies elastic force to restore the pump head (210) to its original state even when pressurized. The elastic member (220) may be provided on the lower side of the pump head (210). At this time, the piston rod (260) may be provided to communicate with the inside of the pump head (210). The piston rod (260) may have a passage formed therein for allowing contents to move to the pump head (210), and an opening communicating with the passage may be formed at an end of the piston rod (260) facing the space of the inner container (500). The end of the piston rod (260) may be accommodated in a cylinder (280) included in the pump device (200). One side of the cylinder (280) may be coupled with the under cap (240). The other side of the cylinder (280) may face the space where the contents of the inner container (500) are accommodated. The internal space of the cylinder (280) may have a piston rod (260) positioned on one side and a check valve (290) positioned on the other side. At this time, a seal cap (270) may be positioned between the piston rod (260) and the cylinder (280), thereby preventing the contents from moving to the outside of the cylinder (280) due to the movement of the piston rod (260).

[0048] When the pump head (210) is pressurized, the piston rod (260) moves toward the internal space of the cylinder (280), and at this time, the check valve (290) can close the opening toward the contents (500) of the cylinder (280). The internal pressure of the cylinder (280) increases, and the contents located inside the cylinder (280) can move outward through the opening of the piston rod (260) and the pump head (210). When the pump head (210) is released from pressurization, the piston rod (260) moves again in the direction in which the internal space of the cylinder (280) expands due to the elastic force of the elastic member (220), and thereby the internal space of the cylinder (280) has a lowered pressure, and the check valve (290) moves, so that the opening toward the contents (500) of the cylinder (280) can be opened. Through the opening of the open cylinder (280), the contents can be moved into the internal space of the cylinder (280).

[0049] As previously described, the decorative member (300) may be configured to be detachably coupled to the inner container (500) so as to couple the inner container (500) to the outer container (400). The decorative member (300) may be supported by the outer container (400). Accordingly, the inner container (500) may be coupled to the outer container (400) by the decorative member (300).

[0050] At this time, the contents container (500) may be configured to be detachable from the outer container (400) based on the rotation of the decorative member (300) with respect to the outer container (400). When the contents are exhausted, the contents container (1) may be refilled with contents by replacing the contents container (500). At this time, the contents container (500) with exhausted contents may be replaced with a contents container (500) with sufficient contents to refill the contents of the contents container (1). At this time, although not illustrated in the embodiment of the present disclosure, any method in which the contents container (500) is detached when the decorative member (300) rotates with respect to the outer container (400) is considered to be included in the present invention. For example, one example may be that the contents container (500) is detached with respect to the outer container (400) by the connection of gears in accordance with the rotation of the decorative member (300).

[0051] More specifically, the inner container (500) can be released from the decorative member (300) based on the rotation of the decorative member (300). The inner container (500) can be released from the outer container (400) based on the release of the decorative member (300). In other words, the inner container (500) can be provided as a separate object from the outer container (400) if the decorative member (300) is not provided. When the release of the decorative member (300) and the inner container (500) occurs, the inner container (500) can be released from the outer container (400) since there is no means for fixing it to the outer container (400). That is, the decorative member (300) can be released from the inner container (500) by rotating relative to the outer container (400).

[0052] As described above, the outer container (400) may have an opening formed on one side spaced apart from the decorative member (300). That the inner container (500) becomes detachable from the outer container (400) based on the rotation of the decorative member (300) may mean that the inner container (500) is configured to be detachable from the outer container (400) through the opening of the outer container (400).

[0053] At this time, the decorative member (300) may include a decorative member engagement portion (331) configured to engage with the content member (500). For example, the decorative member engagement portion (331) may have a screw thread shape. The content member (500) may include a content member engagement portion (530) that protrudes from the content member neck (520) toward the decorative member (300) and engages with the decorative member engagement portion (331). For example, the content member engagement portion (530) may have a screw thread shape.

[0054] More specifically, the decorative member (300) may include an inner portion (330) positioned between the outer container neck (420) and the inner container neck (520), and an inner portion (330) from which a decorative member engagement portion (331) protrudes.

[0055] At this time, the decorative member (300) may include an outer portion (310) positioned on the outside of the outer container neck (420). The outer portion (310) may cover the outer container neck (420). The decorative member (300) may include a connecting portion (320) connecting the inner portion (330) and the outer portion (310). For example, the connecting portion (320) may connect the upper end of the inner portion (330) and the upper end of the outer portion (310). The connecting portion (320) may be configured to be supported by the outer container neck (420). In other words, this may mean that the outer container neck (420) may be inserted into the space between the inner portion (330) and the outer portion (310), and the upper end of the outer container neck (420) may extend to the connecting portion (320). While the decorative member (300) rotates, the connecting portion (320) can be supported by the upper end of the outer container neck (420). Furthermore, while the decorative member (300) rotates, the outer portion (310) and the inner portion (330) can be guided by the outer container neck (420), respectively, to guide the rotation of the decorative member (300).

[0056] At this time, the decorative member (300) may include a support flange (332) protruding from the inner side (330) toward the pump device (200). As described above, the pump device (200) is configured to pump the contents accommodated in the container (500) and may be supported by the end of the cylinder (280). Alternatively, the support flange (332) may be supported by the container (500). Accordingly, the support flange (332) may be supported by the pump device (200) to prevent movement while the decorative member (300) is rotated.

[0057] In the above, a structure in which the contents container (500) is separated according to the rotation of the decorative member (300) has been described. However, in general, while using the contents container (1), the decorative member (300) is rotated, and the contents container (500) is separated, which may cause an unexpected situation. To prevent this, the decorative member (300) may be arranged so that the decorative member (300) rotates only when it moves to a specific position.

[0058] That is, the decorative member (300) can be moved to a fixed position fixed to the inner container (500) to prevent rotation with respect to the outer container (400) and to a fixed release position spaced apart from the inner container (500) to allow rotation with respect to the outer container (400). This will be described in more detail below.

[0059] Furthermore, since the decorative member (300) and the inner container (500) are coupled while the decorative member (300) is rotated, the inner container (500) may also rotate. However, in order for the decorative member (300) to be separated from the inner container (500), the decorative member (300) may need to rotate with respect to the inner container (500) rather than together with the inner container (500). Therefore, while the decorative member (300) is rotated with respect to the outer container (400), the inner container (500) needs to be prevented from rotating. A structure for this will be described in more detail below.

[0060] Figure 4 is an exploded view of a content device (500) and a decorative member (300) according to an embodiment of the present invention.

[0061] Referring to FIGS. 2 and 4, the content member (500) can be prevented from rotating by the outer container (400) while the decorative member (300) rotates.

[0062] The outer container (400) may include an outer container guide (440) that protrudes toward the inner container (500). For example, the outer container guide (440) may have a shape like a gear tooth, as illustrated in FIG. 2. The outer container guide (440) may extend in the circumferential direction. However, although FIG. 2 illustrates that the outer container guide (440) extends in the entire circumferential direction, the present invention is not limited thereto, and the outer container guide (440) may extend in a portion of the circumferential direction. Furthermore, the outer container guide (440) may protrude from the outer container neck (420) toward the inner container body (510). The outer container guide (440) can be prevented from protruding toward the inner container (500) while the inner container (500) is coupled to the outer container (400) by the decorative member (300), but protruding beyond the inner surface of the outer container neck (420). Accordingly, the outer container guide (440) can be prevented from interfering with the movement of the inner container neck (520) while the inner container neck (520) is accommodated in the outer container neck (420) along the inner surface of the outer container neck (420).

[0063] The inner container (500) may include an inner container guide (560) that protrudes toward the outer container (400) to engage with the outer container guide (440) so as to prevent rotation with respect to the outer container (400) while the decorative member (300) is rotated to separate the inner container (500). In other words, as mentioned above, while the decorative member (300) is rotated, the inner container (500) needs to be fixed in rotational movement so as to have relative rotation with respect to the decorative member (300). For this purpose, the inner container (500) may be fixed in rotational movement with respect to the outer container (400). Furthermore, while the decorative member (300) is rotated, the inner container (500) may be slidably moved with respect to the outer container (400) so as to be moved in a direction in which it is separated through the lower opening of the outer container (400). Accordingly, the relationship between the contents (500) and the outer container (400) may be such that the contents (500) is prevented from rotating by the outer container (400) while the connection with the decorative member (300) is released, but the contents (500) can slide.

[0064] Additionally, the outer container guide (440) may be positioned on the lower side of the outer container neck (420), and thus may be spaced apart from the decorative member (300). This may be because the decorative member (300) may be supported by the upper end of the outer container neck (420).

[0065] For example, as illustrated in FIG. 4, the inner container guide (560) may have a gear tooth shape that meshes with the outer container guide (440) having a gear tooth shape. The inner container guide (560) may extend along the circumferential direction with a shorter length than the outer container guide (440). If the outer container guide (440) extends over the entire circumferential direction, even if the inner container guide (560) extends only over a part of the circumferential direction, the inner container guide (560) may be inserted into the outer container guide (440) when the inner container guide (560) has an arbitrary rotation angle.

[0066] The content guide (560) may be included in the content neck (520). More specifically, the content guide (560) may extend from the content body (510). For example, the content guide (560) may be positioned on the upper side of the content body (510), and the content engagement portion (530) may be positioned on the upper side of the content guide (560). Since the decorative member (300) is positioned on the upper side of the outer container guide (440), the decorative member engagement portion (331) may be positioned on the upper side of the outer container guide (440), and the content guide (560) that engages with the outer container guide (440) may be positioned lower than the content engagement portion (530) that engages with the decorative member engagement portion (331).

[0067] Furthermore, the decorative member (300) may include a pair of fixing protrusions (334) spaced apart from each other so that an insertion groove (335) is formed therebetween. The fixing protrusions (334) may protrude toward the inner body (510). The inner body (500) may include an insertion protrusion (550) protruding toward the insertion groove (335) so as to be inserted into the insertion groove (335). More specifically, the inner body (500) may include an inner body step portion (540) in which an inner body engagement portion (530) is formed, and the inner body step portion (540) may be formed to be stepped with respect to the inner body (500). The insertion protrusion (550) may protrude from the inner body step portion (540) toward the decorative member (300). The decorative member (300) can be positioned in a fixed position when the insertion protrusion (550) is inserted into the insertion groove (335). The decorative member (300) can be positioned in a rotatable fixed release position when the insertion protrusion (550) is moved away from the outer container (400) and the insertion protrusion (550) is disengaged from the insertion groove (335).

[0068] Figure 5 is an exploded view of an outer container (400) and a decorative member (300) according to an embodiment of the present invention.

[0069] Referring to FIG. 5, the decorative member (300) can be coupled to the outer container (400) so as to be rotatable with respect to the outer container (400). As mentioned above, the decorative member (300) can be fitted to the neck of the outer container (400).

[0070] The outer container neck (420) may include a rotation guide rib (430) protruding outward. The rotation guide rib (430) may extend in the circumferential direction of the outer container neck (420). The decorative member (300) may include a rotation guide groove (333) into which the rotation guide rib (430) is inserted. The rotation guide groove (333) may extend corresponding to the rotation guide rib (430) to accommodate the rotation guide rib (430). Accordingly, the rotation guide groove (333) may extend along the circumferential direction of the decorative member (300). The rotation guide groove (333) may be formed on a side from the outer side (310) toward the inner side (330). Accordingly, while the decorative member (300) is rotated with respect to the outer container (400), the rotation guide rib (430) is received in the rotation guide groove (333) and rotates, thereby guiding the rotation of the decorative member (300).

[0071] The rotation guide rib (430) can be coupled to the rotation guide groove (333) by a fitting connection. Accordingly, when a predetermined force or more is applied to move the decorative member (300) away from the outer container (400), the rotation guide rib (430) can be arranged to be detached from the rotation guide groove (333). Since the decorative member (300) needs to first be moved away from the outer container (400) when the inner container (500) is to be separated from the outer container (400), the rotation guide rib (430) and the rotation guide groove (333) need to be provided to enable the movement of the decorative member (300). However, when the decorative member (300) is not moved, the rotation guide rib (430) can be fitted into the rotation guide groove (333) to a degree that prevents the decorative member (300) from being accidentally moved upward.

[0072] FIG. 6 is a diagram illustrating a state of use of a content container (1) according to an embodiment of the present invention. In particular, (a) of FIG. 6 illustrates the content container (500) being separated from the outer container (400). (b) of FIG. 6 illustrates the refill container (2). (c) of FIG. 6 illustrates the refill container cap (600) being separated from the refill container (2). (d) of FIG. 6 illustrates the content container (500) of the refill container (2) being inserted into the outer container (400).

[0073] Referring to Fig. 6, the replacement of the contents container (500) that has exhausted its contents can be explained below.

[0074] By moving the decorative member (300) away from the outer container (400), the decorative member (300) can be moved from a fixed position to an unlocked position. Accordingly, the decorative member (300) can be rotated with respect to the inner container (500).

[0075] While the decorative member (300) is rotated relative to the outer container (400), the inner container (500) is released from the connection with the decorative member (300) and can be moved away from the decorative member (300). At this time, the inner container (500) is restricted from rotating relative to the outer container (400) and can only be moved in the sliding direction, so that the inner container (500) can be moved away from the decorative member (300) without being rotated relative to the decorative member (300) while the decorative member (300) is rotated.

[0076] When the combination of the decorative member (300) and the inner container (500) is released, the inner container (500) can be separated from the outer container (400) through the lower opening formed in the outer container (400).

[0077] A refill container (2) is prepared, and the refill container cap (600) can be rotated to open the contents (500) included in the refill container (2). At this time, a screw thread may be formed on the inside of the refill container cap (600) so as to be configured to engage with the contents engaging portion (530).

[0078] A new content container (500) can be accommodated in the outer container (400) through the lower opening of the outer container (400). Thereafter, the decorative container can be rotated in the opposite direction to the direction in which the content container (500) is separated, and combined with the content container (500). After the decorative container is combined with the content container (500), it can be moved downward and fixed.

[0079] As described above, the best practice embodiments have been disclosed in the drawings and specifications. While specific terminology has been used herein, it is solely for the purpose of describing the present invention and is not intended to limit the scope of the invention as defined in the claims. Therefore, those skilled in the art will understand that various modifications and equivalent embodiments are possible. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
