Description

Rotary discharge container

[0001] The present invention relates to a rotary dispensing container, and more particularly, to a rotary dispensing container configured to dispense a certain amount of contents by rotating a part of the container.

[0002] Typically, a container consists of a housing that holds the contents and a cap. The cap is opened from the housing or housing unit, and the contents are dispensed using a cosmetic tool or hands. However, this method can pose hygiene issues, as the remaining contents can become contaminated or spoiled by contaminated hands or tools. Furthermore, the cap must be separated from the housing or housing unit before the cosmetics can be used, which can be inconvenient.

[0003] Another type is a content container configured to dispense content by a dispensing member such as a dispenser. However, this method requires complex components such as a pump assembly, which increases the unit cost of the container and complicates the assembly process.

[0004] Accordingly, containers with simpler components were developed that would elevate the contents and push them toward the outlet. However, this method can lead to problems such as difficulty in controlling the amount of contents discharged, such as excessive contents discharge. Furthermore, there is a risk of residual contents remaining around the outlet, potentially leading to contamination of the area around the outlet.

[0005] The present invention is intended to solve the above problem, and provides a container for contents that can discharge a fixed amount of contents by a rotational motion and can be used hygienically because no contents remain around the discharge port.

[0006] 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.

[0007] According to an embodiment of the present invention, a contents container is provided. The contents container includes a housing unit configured to accommodate contents; and an elevating unit positioned within the housing unit and configured to move the contents, wherein the elevating unit includes a support member rotatable with respect to the housing unit; and a piston that is elevated by rotation of the support member to move the contents, and when the support member is rotated at a predetermined angle, the support member can be configured to ascend and descend.

[0008] According to the present invention, the contents can be discharged with a simple rotational motion, making it convenient to use, and the contents can be discharged in fixed quantities according to a preset rotation angle, making it easy to control the discharge amount.

[0009] The contents container according to the present invention is configured to suck back the contents stuck to the discharge port into the housing unit after quantitative discharge, thereby preventing over-discharge of the contents and enabling hygienic use as no residual contents remain around the discharge port.

[0010] The contents container according to the present invention has the advantage of being able to set the discharge amount at a time by the shape of the support protrusion, making it very easy to set the discharge amount and change the design.

[0011] The contents container according to the present invention can be composed of a single series of materials, so that it can be discharged at once without the need to separate parts, making it easy to recycle and environmentally friendly.

[0012] In order to more fully understand the drawings cited in the detailed description of the present invention, a brief description of each drawing is provided.

[0019] According to an embodiment of the present invention, a contents container is provided. The contents container includes a housing unit configured to accommodate contents; and an elevating unit positioned within the housing unit and configured to move the contents, wherein the elevating unit includes a support member rotatable with respect to the housing unit; and a piston that is elevated by rotation of the support member to move the contents, and when the support member is rotated at a predetermined angle, the support member can be configured to ascend and descend.

[0020] The contents container further includes a nozzle cap coupled to the housing unit and having a discharge port formed therein, and when the nozzle cap is rotated in a direction that raises the piston, the space between the piston and the discharge port is reduced to enable discharge of the contents, and when the support member is lowered, the space between the piston and the discharge port is increased to enable suction of the contents.

[0021] The housing unit may include a housing that accommodates a support member, the housing includes a rail projection that projects toward the support member, the support member includes a support projection that projects toward the housing, and the support projection and the rail projection may be configured to contact each other while the support member rotates as the nozzle cap rotates.

[0022] The support member can be configured to be movable to a discharge position where the end of the support projection contacts the end of the rail projection and a suction position where the end of the support projection contacts the inner lower surface of the housing.

[0023] The support member can be configured to rotate upward from a suction position to a discharge position and to rotate downward from a discharge position to a suction position.

[0024] The rail projection may include an inclined support sloped surface facing upward so as to guide rotation from a suction position to a discharge position while the support member is rotated.

[0025] The support slope surfaces may be provided in pairs on opposite sides of the end portion so that the rail projections are guided to rotate from the discharge position to the suction position while the support member rotates.

[0026] The support projection may include a rail slope surface corresponding to the support slope surface.

[0027] The rail slope surface can be in contact with the support slope surface while the support member is in the suction position.

[0028] At least one of the support projections and the rail projections may be configured to prevent idling when their centers of rotation overlap each other.

[0029] The rail projection can be positioned closer to the axis of rotation than the support projection while the support member is in the suction position.

[0030] The rail projections can be provided in a square ring shape.

[0031] The cylinder may further include a cylinder positioned between the piston and the housing to guide the upward and downward movement of the piston, the support member including a support portion from which a support projection protrudes and a screw rod extending from the support portion to penetrate the piston and engaging with the piston, and the cylinder may include an elastic projection protruding downward to elastically bias the support member toward the suction position while the support member is in the discharge position.

[0032] The elastic projection includes a fixed end and a movable free end, the free end being capable of contacting a support.

[0033] The housing may be formed with a rail groove capable of accommodating at least a portion of the support projection while the support member is in the suction position.

[0034] The contents container may be composed of a single series of materials.

[0035] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the contents described in the attached drawings.

[0039] Fig. 1 is a perspective view of a contents container (1) according to one embodiment of the present invention. Furthermore, Fig. 1(a) is a drawing showing a nozzle being rotated relative to a housing unit (H) with an overcap (100) removed. Fig. 1(b) is a drawing showing a further rotation of Fig. 1(a) such that contents (2) are moved outside the contents container (1).

[0040] Referring to Fig. 1, a contents container (1) according to one embodiment of the present invention is described.

[0041] A contents container (1) may be provided to accommodate contents (2). Here, the contents (2) may be, for example, cosmetics. Furthermore, the cosmetics described below may be liquid. Of course, the spirit of the present invention is not limited to liquid cosmetics, and the spirit of the present invention may also be applied to solid or semi-solid cosmetics, as described with reference to FIG. 5 below. However, for convenience of explanation, one embodiment of the present invention is described as being applied to a contents container (1) that accommodates liquid cosmetics.

[0042] As illustrated in Fig. 1(a), the contents container (1) may include a housing unit (H) configured to accommodate contents (2) and a nozzle cap (200) covering the housing unit (H). A discharge port (201) (Fig. 4) through which the contents (2) are moved may be formed in the nozzle cap (200). The contents container (1) may be positioned on the discharge port (201) and provided with a nozzle tip (300) for controlling discharge of the contents (2).

[0043] Despite its name, the housing unit (H) may be formed singly. However, for convenience of explanation, the following description of an embodiment of the present invention assumes and describes that the housing unit (H) includes multiple configurations.

[0044] The nozzle cap (200) can be rotatably coupled to the housing unit (H). While the nozzle cap (200) is rotated, the contents (2) can be moved through the discharge port (201) by pressing the nozzle tip (300). At this time, in order to prevent the contents (2) from remaining adjacent to the discharge port (201), it is necessary to suck a portion of the contents (2) back into the housing unit (H). Hereinafter, a contents container (1) according to one embodiment of the present invention having such an effect will be described in more detail.

[0045] Fig. 2 is an exploded view of the contents container (1) illustrated in Fig. 1. Fig. 3 is an exploded view of the housing unit (H) of the contents container (1) illustrated in Fig. 2. Fig. 4 is a cross-sectional view taken along line IV-IV' of the contents container (1) illustrated in Fig. 1. Furthermore, enlarged views of some components are illustrated in Figs. 2 and 3. Fig. 4(a) is a cross-sectional view of the over cap (100) coupled to the housing unit (H) and the support member (400) in the suction position. Fig. 4(b) is a cross-sectional view of the support member (400) in the discharge position after the over cap (100) is removed.

[0046] Referring to FIGS. 2 to 4, the detailed configuration and operation of the contents container (1) according to one embodiment of the present invention will be described.

[0047] As illustrated in FIG. 2, the contents container (1) may include a housing unit (H), a cap (C) and / or an elevating unit (L).

[0048] The housing unit (H) may be configured to accommodate contents (2) on the inside. An opening communicating with a space for accommodating the contents (2) may be formed on one side of the housing unit (H). A cap (C) may be provided to cover the opening formed in the housing unit (H). Furthermore, the cap (C) may be configured to have a discharge port (201). The space for accommodating the contents (2) formed in the housing unit (H) is communicated with the discharge port (201), so that the contents (2) can be moved from the inside of the housing unit (H) to the outside of the contents container (1) through the discharge port (201). The elevating unit (L) may be configured to elevate the contents (2) and move them toward the discharge port (201). The elevating unit (L) may be located on the inside of the housing unit (H) and configured to pressurize the contents (2).

[0049] The housing unit (H), cab (C) and / or lifting unit (L) are described in more detail below. However, for convenience of explanation, the order of explanation is cab (C), lifting unit (L), and housing unit (H).

[0050] The cap (C) may include an over cap (100), a nozzle cap (200) and / or a nozzle tip (300).

[0051] The nozzle cap (200) can be coupled to the housing unit (H) so as to directly cover the opening formed in the housing unit (H). The above-described discharge port (201) can be formed in the nozzle cap (200). The over cap (100) can be provided to cover the nozzle cap (200). Since the nozzle cap (200) is configured to directly form the discharge port (201) through which the contents (2) are discharged, it needs to be protected in order to use the contents container (1) for a long time. At this time, the lifting unit (L) can be provided so that the contents (2) are positioned within the housing unit (H) and the nozzle cap (200). In particular, the nozzle cap (200) can include a rod mounting portion (410) (210) protruding toward the housing unit (H) on the inside. The load mounting portion (410) (210) can rotate together with the support member (400) described below, and can allow the support member (400) to move up and down. This will be described in more detail in the description with reference to FIG. 4. For reference, the nozzle cap (200) may have an overall square pillar shape to make it easy to know the amount of rotation. Furthermore, the inner side may be provided with a shape corresponding to the side of a cylinder. This is because the corresponding part of the housing unit (H) that is rotatably coupled to the inner side of the nozzle cap (200) also has a cylindrical side shape, and the housing unit (H) and the nozzle cap (200) may be provided to be rotatable with respect to each other. The nozzle cap (200) may be formed of a plastic material.

[0052] The over cap (100) can protect the nozzle cap (200). Furthermore, when the over cap (100) has a transparent or translucent material, the shape and color of the nozzle cap (200) can be seen through the over cap (100), thereby enhancing the aesthetic appeal of the cap (C).

[0053] As illustrated in FIG. 4, the nozzle tip (300) can be coupled to the nozzle cap (200) and the outlet (201). The nozzle tip (300) may include a wide cross-sectional portion to cover the outlet (201), a portion provided to penetrate the outlet (201), and a portion positioned inside the outlet (201) to prevent separation of the nozzle tip (300) from the nozzle cap (200). Rather than completely sealing the outlet (201) of the nozzle cap (200), when pressure is applied to the nozzle tip (300) to cause the contents (2) to come out, the nozzle tip (300) may be deformed, and the contents (2) may move to the outside of the contents container (1) through the outlet (201), or may move to the inside of the contents container (1).

[0054] As shown in FIG. 2, the lifting unit (L) may include a support member (400) and a piston (500).

[0055] The support member (400) and the piston (500) interact with each other and can raise or lower the piston (500). In the present disclosure, the rising of the piston (500) is described as the standard. In the case of the lowering of the piston (500), the description may be understood in the opposite way. The support member (400) may be rotatably coupled to the housing unit (H). The support member (400) may be supported by the housing unit (H). The piston (500) may be rotatably coupled to the support member (400) so as to be raised or lowered by the rotation of the support member (400) in order to move the contents (2). Additionally, the support member (400) and the piston (500) may be formed of a plastic material.

[0056] The support member (400) may include a screw rod (420) having threads formed therein. The screw rod (420) may be inserted into a hollow portion of the piston (500). As illustrated in FIG. 4, the piston (500) may include an engagement portion (510) protruding toward the hollow portion. The threads of the piston (500) rod engage with the engagement portion (510), such that the engagement portion (510) of the piston (500) moves according to the rotation of the piston (500) rod, thereby allowing the piston (500) to rise. In other words, the screw rod (420) may extend from the support member (430) to penetrate the piston (500) and engage with the piston (500).

[0057] The support member (400) may include a support portion (430) having a cross-sectional area greater than the cross-sectional area of ​​the piston (500) rod, as illustrated in FIG. 2, on the lower side of the piston (500). The support portion (430) may position the piston (500) on the lower side of the piston (500), as illustrated in FIG. 4. The support portion (430) may indirectly prevent the piston (500) from being separated from the screw rod (420). Furthermore, the support portion (430) may prevent the cylinder (600) described below from being separated downward. For reference, the support portion (430) may have a circular plate shape.

[0058] The support member (400) may include a support protrusion (440) protruding from the lower side of the support portion (430). The support protrusion (440) may raise or lower the entire lifting member by interaction with the rail protrusion (710) of the housing (700) described later. The support protrusion (440) may not be circular. The support protrusion (440) may be substantially rectangular. The support protrusion (440) protrudes toward the housing unit (H) and may come into contact with the housing unit (H). The relationship between the support protrusion (440) and the rail protrusion (710) is described in more detail in the description with reference to FIG. 4.

[0059] The support member (400) may include a mounting portion (410) coupled to the nozzle cap (200) on the upper side of the piston (500) rod. The mounting portion (410) may be coupled to the nozzle cap (200) by being inserted into the rod mounting portion (410)(210) of the nozzle cap (200). As previously mentioned, the mounting portion (410) may be coupled so as to rotate together with the rod mounting portion (410)(210) while allowing for up and down movement. At this time, as illustrated in FIG. 2, the mounting portion (410) may have a cross-shaped cross section, and the rod mounting portion (410)(210) may be formed to have a hole corresponding to the mounting portion (410). Furthermore, the hole of the rod mounting portion (410)(210) may be provided to communicate with the discharge port (201).

[0060] The piston (500) may be formed hollow as previously mentioned. The piston (500) may have a substantially cylindrical shape. However, the piston (500) may be formed with a concave piston guide groove (501) toward the center so that the vertical movement is guided by the cylinder (600). The piston guide groove (501) may extend in the vertical direction. The function of the piston guide groove (501) will be described below together with the configuration of the cylinder (600).

[0061] As illustrated in FIG. 3, the housing unit (H) may include a cylinder (600), a housing (700), and / or an over-housing (800) (700). The housing (700) may accommodate the cylinder (600). The over-housing (800) (700) may cover the housing (700). The cylinder (600) may accommodate a piston (500). Furthermore, a cross-section of the inner space of the cylinder (600) may be formed to correspond to a cross-section of the piston (500), thereby guiding the up-and-down movement of the piston (500). For reference, the cylinder (600) and / or the piston (500) may be made of a plastic material. The cylinder (600) may be positioned between the piston (500) and the housing (700) to guide the up-and-down movement of the piston (500). The housing (700) may accommodate a support member (400).

[0062] The cylinder (600) may include a piston guide protrusion (601) that protrudes inwardly and extends in an up-and-down direction. The piston guide protrusion (601) may be accommodated in the piston guide groove (501) of the piston (500) mentioned above to guide the up-and-down movement of the piston (500). Furthermore, while the piston guide protrusion (601) is accommodated in the piston guide groove (501), rotation of the piston (500) relative to the cylinder (600) may be prevented. Accordingly, rotation of the piston (500) may be restricted during an upward or downward movement.

[0063] The cylinder (600) may include a cap fixing rib (610) that protrudes on the side on which the nozzle cap (200) is mounted. The nozzle cap (200) may be mounted on the cap fixing rib (610) to prevent the nozzle cap (200) from being separated from the cylinder (600).

[0064] The cylinder (600) may include a housing fixing protrusion (620). The housing fixing protrusion (620) may guide the coupling of the cylinder (600) and the housing (700) and prevent the cylinder (600) from being separated from the housing (700). At this time, the section of the cylinder (600) that is coupled to the nozzle cap (200) may have a circular cross-section, but the section of the cylinder (600) that is coupled to the housing (700) may have a square cross-section. This may be because the nozzle cap (200) may be rotatable with respect to the cylinder (600), but the cylinder (600) needs to be rotated together with the housing (700).

[0065] The cylinder (600) may include an elastic protrusion (630) protruding downward. The elastic protrusion (630) may include a free end on one side and a fixed end on the other side. That is, the elastic protrusion (630) may include a fixed end connected to an adjacent member and / or a movable free end. In this case, the free end may contact the support member (430). The elastic protrusion (630) may protrude downward from the free end. As illustrated in FIG. 4, the elastic protrusion (630) may press the support member (400) downward from the upper side of the support member (430). Accordingly, the support protrusion (440) may be pressed toward the lower inner surface of the housing (700) on which the rail protrusion (710) described below is formed. In other words, the elastic protrusion (630) can be positioned on the opposite side of the support protrusion (440) with respect to the support member (430) so as to elastically bias the support member (400) toward the suction position while the support member (400) is in the discharge position described below.

[0066] The housing (700) may include an insertion protrusion (730) protruding upward. As illustrated in FIG. 4, the insertion protrusion (730) may be inserted into the support member (400) along the rotational axis of the support member (400). However, the housing (700) may be rotatable independently of the support protrusion (440). This may be because the support member (430) inserted into the housing (700) may be a circular plate, or because the cross-section of the insertion protrusion (730) is circular.

[0067] The housing (700) may include a rail protrusion (710) that protrudes toward the support member (400). The rail protrusion (710) may protrude toward the support member (400) so as to come into contact with the support protrusion (440) while the support protrusion (440) rotates. The rail protrusion (710) may have a rectangular ring shape, as illustrated in FIG. 3. However, the present invention is not limited thereto, and the rail protrusion (710) may have a polygonal shape other than a rectangular shape, as illustrated in another embodiment illustrated in FIG. 6. Furthermore, the rail protrusion (710) may form an open curve rather than a closed curve. The same applies to the support protrusion (440). As illustrated in FIG. 4, the rail protrusion (710) may have a different size from the support member (400). This may be to allow the support member (400) to move to the discharge position and suction position described later, as described later. At this time, as illustrated in FIG. 4, the rail protrusion (710) may be positioned closer to the rotation axis than the support protrusion (440). The relationship between the rail protrusion (710) and the support protrusion (440) will be described in more detail in the related description below.

[0068] The housing (700) may be formed with a rail groove (720) that can accommodate at least a portion of the support protrusion (440) while the support member (400) is in the suction position. The rail groove (720) may be arranged such that the distance between the two closest points of the edges is greater than or equal to the distance between the two farthest points of the support protrusion (440). While the support member (400) rotates, the two farthest points of the support protrusion (440) may rotate while forming a circle whose diameter is the distance between the two points. Accordingly, the edge of the rail groove (720) may be spaced outwardly with respect to the rotational axis relative to the support protrusion (440) so as to prevent the support protrusion (440) from moving up and down by the rail groove (720). Furthermore, the rail groove (720) may correspond to the shape of the support portion (430). Accordingly, the rail groove (720) may guide the rotation of the support portion (430).

[0069] Below, the operation of the contents container (1) is described with reference to Fig. 4.

[0070] In order to use the contents container (1), the over cap (100) can be separated to expose the nozzle cap (200). The nozzle cap (200) can be rotated with respect to the housing unit (H). The nozzle cap (200) can be coupled to the support member (400) so as to rotate together with the support member (400), so that the support member (400) can be rotated according to the rotation of the nozzle cap (200). As described above, the lifting unit (L) can include the support member (400) and a piston (500) that is rotatably coupled to the support member (400). The piston (500) can be elevated according to the rotation of the support member (400). The contents (2) can be positioned above the piston (500). The contents (2) may be moved upward according to the movement of the piston (500) and may be moved outside the nozzle cap (200) by pushing the nozzle tip (300) through the discharge port (201) of the nozzle cap (200). The contents (2) moved outside the contents container (1) may be used by the user.

[0071] When the support member (400) rotates at a predetermined angle, the support member (400) may be configured to rise and then fall. When the support member (400) rises, the space between the piston (500) and the discharge port (201) decreases, allowing the contents to be discharged, and when the support member (400) descends, the space between the piston (500) and the discharge port (201) increases, allowing the contents to be sucked in. At this time, the support member (400) rotates in a direction that raises the piston (500), and the piston (500) may rise as the support member (400) rotates.

[0072] More specifically, the lifting unit (L) can be guided by the housing unit (H) to move up and down while the support member (400) rotates in the rotational direction that raises and lowers the piston (500). While the support member (400) moves up and down, the piston (500) presses the contents (2) upward, and thus, the contents (2) can easily press the nozzle tip (300) while being discharged, so that the contents (2) can be easily discharged. The lifting unit (L) can be configured to be guided by the housing unit (H) to move down while the support member (400) rotates in the rotational direction that raises and lowers the piston (500) so as to increase the volume of the space between the piston (500) and the discharge port (201). The space between the piston (500) and the discharge port (201) accommodates the contents (2), and as the volume of the space increases, negative pressure is generated, so that the contents (2) adjacent to the discharge port (201) can be sucked back into the housing unit (H). Accordingly, the contents (2) do not remain around the discharge port (201), so that the contents container (1) can be used cleanly. In more detail, as described below, when the support member (400) includes a support protrusion (440) having a support slant surface (440A), and a rail slant surface (710A) corresponding to the support slant surface (440A) is provided, the lifting unit (L) can move downward after the rotation of the support member (400) is completed. However, the idea of ​​the present invention can also be applied even when the lifting unit (L) moves downward during the rotation of the support member (400).

[0073] That is, the support member (400) can be configured to move to a discharge position where the end of the support protrusion (440) contacts the end of the rail protrusion (710). The support member (400) can be configured to be positioned closer to the lower surface of the housing (700) than the discharge position, and can be configured to move to a suction position where the end of the support protrusion (440) contacts the inner lower surface of the housing (700).

[0074] The support member (400) can be moved to the suction position and the discharge position while the support member (400) rotates at a predetermined angle, taking into account the discharge position and the suction position. More specifically, the lifting unit (L) can move upward while the support member is moved from the suction position to the discharge position. The lifting unit (L) can move downward while the support member is moved from the discharge position to the suction position. It can be understood that the support member (400) is rotated from the first discharge position to the second discharge position formed at a different angle.

[0075] At this time, the rail protrusion (710) may include an inclined support slope surface (440A) facing upward toward the end so as to guide movement from the suction position to the discharge position while the support member (400) is rotated. The support slope surfaces (440A) may be provided in pairs on opposite sides with respect to the end so as to guide movement of the rail protrusion (710) from the discharge position to the suction position while the support member (400) is rotated. The support protrusion (440) may include a rail slope surface (710A) corresponding to the support slope surface (440A).

[0076] The rail inclined surface (710A) can be in contact with the supporting inclined surface (440A) while the supporting member (400) is in the suction position. While the supporting member (400) is moved from the suction position to the discharge position, the supporting protrusion (440) can be raised so that the supporting member (400) is in contact with the rail protrusion (710). At this time, while the supporting protrusion (440) is raised, the supporting inclined surface (440A) can be pressed by the rail inclined surface (710A) and the supporting protrusion (440) can be rotated. While the supporting member (400) is moved from the discharge position to the suction position, the piston (500) can be raised by the relative motion with the supporting member (400) to continuously move the contents (2) through the discharge port (201). While the support member (400) is moved from the discharge position to the suction position, the support protrusion (440) can be rotated while the support inclined surface (440A) is supported by the rail inclined surface (710A). Accordingly, the contents (2) can be moved into the housing unit (H) through the discharge port (201). In this case, in order to achieve the intended effect, the space provided for the contents (2) to be positioned as they decrease as the piston (500) rises according to the rotation of the support member (400) and the space provided for the contents (2) to be positioned as they increase as the support member (400) is moved from the discharge position to the suction position may be larger.

[0077] In other words, while the nozzle cap (200) is rotated in one direction, the support member (400) can be rotated together with the nozzle cap (200) and moved up and down from the suction position to the discharge position and back again from the discharge position to the suction position. When the support protrusion (440) is a square annular shape and the rail protrusion (710) is a square annular shape, the above operation can be completed and performed again with a rotation of 90°. At this time, while the nozzle cap (200) is rotated from 0° to 20°, the support member (400) is moved from the suction position to the discharge position, and while the nozzle cap (200) is rotated from 20° to 70°, the support member (400) is moved from the discharge position to the suction position so that the contents (2) can be discharged, and when the nozzle cap (200) is rotated from 70° to 90°, the support member (400) can be moved from the discharge position to the suction position. More specifically, by the interaction of the support slope surface (440A) and the rail slope surface (710A) of the rail protrusion (710), after the nozzle cap (200) is rotated from 70° to 90°, the support member (400) can be moved from the discharge position to the suction position.

[0078] For the above operation, at least one of the support protrusion (440) and the rail protrusion (710) may not be circular in shape to prevent idling when their centers of rotation overlap. This is because the support protrusion (440) may be pressed by the rail protrusion (710) as the support member (400) rotates. If idling of the support protrusion (440) occurs, the support protrusion (440) may not be able to interact with the rail protrusion (710).

[0079] As mentioned above, the rail protrusion (710) may be positioned closer to the rotation axis than the support protrusion (440) while the support member (400) is in the suction position. This may be because the rail protrusion (710) may not completely correspond to the support protrusion (440) so that the support member (400) can be moved to the suction position. At this time, the distance between the two furthest points of the ends of the rail protrusion (710) may be greater than or equal to the distance between the two closest points of the ends of the support protrusion (440). Accordingly, when the support member (400) is in the suction position, the support protrusion (440) may not interact with the rail protrusion (710).

[0080] Below, embodiments different from the above embodiments are described. Commonalities with the above embodiments will be omitted as much as possible, and the description of other embodiments will focus on differences. In other words, it should be clear that any details not described in the other embodiments can be supplemented by the above embodiments.

[0081] Figure 5 is an exploded view of a contents container (1) according to another embodiment of the present invention.

[0082] Referring to FIG. 5, a nozzle cap (200) according to another embodiment of the present invention is described.

[0083] Another embodiment differs from the above embodiment in that the nozzle cap (200) includes a grinder (220-1).

[0084] The contents (2) according to another embodiment may be in a solid or semi-solid form. The grinder (220-1) may grind the contents in a solid or semi-solid form and discharge them outward.

[0085] The grinder (220-1) may be positioned adjacent to the outlet (201) extending in one direction. The grinder (220-1) may extend parallel to the outlet (201) and protrude toward the inside of the nozzle cap (200). While the contents (2) are raised by the rise of the piston (500), the contents (2) are ground by the grinder (220-1), and the ground contents (2) may be moved to the outside of the nozzle cap (200).

[0086] At this time, as described in the above embodiment, as the support member (400) moves to the suction position, the contents (2) adjacent to the discharge port (201) flow back into the housing unit (H), so that the discharge port (201) can be cleaned.

[0087] Fig. 6 is an enlarged perspective view of a support member (400) according to another embodiment of the present invention. Fig. 6(a) is a drawing illustrating a triangular support protrusion (440-2). Fig. 6(b) is a drawing illustrating a hexagonal support protrusion (440-3). Fig. 6(c) is a drawing illustrating an octagonal support protrusion (440-4).

[0088] Referring to FIG. 6, a support protrusion (440) of a support member (400) according to another embodiment of the present invention is described.

[0089] Another embodiment differs from the above embodiment in that the shapes of the support protrusions (440-2, 440-3, 440-4) are different.

[0090] The support protrusion (440) may have various shapes, not just a rectangular shape. For example, the support protrusion (440) may have a triangular shape as illustrated in FIG. 6(a), a hexagonal shape as illustrated in FIG. 6(b), or an octagonal shape as illustrated in FIG. 6(c). Furthermore, the support protrusion (440) may have other polygonal shapes, or even non-polygonal shapes. Furthermore, the rail protrusion (710) may also have various shapes.

[0091] When the shape of the support protrusions (440-2, 440-3, 440-4) changes, the movement of the support member (400) according to the rotation angle may also change.

[0092]

[0093] According to an embodiment, the contents container (1) may be formed from a single series of materials. For example, all components constituting the contents container (1) may be formed from a polypropylene (PP) series. However, the present invention is not limited to polypropylene and may be formed from various materials. Accordingly, the contents container (1) can be disposed of as a single unit without the need for separation, thereby facilitating recycling and being environmentally friendly.
