Description

Technical Field

[0001] This invention relates to cosmetic containers and cosmetics using the cosmetic containers. Background Technology

[0002] In cosmetic containers, there are known containers that have a lid that is attached to a part of the main body of the cosmetic container. These lids are fixed to the main body of the container by various methods.

[0003] For example, Patent Document 1 discloses a configuration in which a locking protrusion is provided on the lid and a corresponding annular locking recess is provided on the container body, and the two are fixed by locking together. Furthermore, Patent Document 2 discloses a configuration in which the sliding resistance between the inner cap and the container body is used to create a sense of luxury. Moreover, Patent Document 3 discloses a configuration in which magnetic force is used to attract the container body and the lid together.

[0008] Patent Document 3: Japanese Patent Application Publication No. 2020-89680

[0009] Furthermore, if the lid is not securely fixed to the main body of the cosmetic container, it may accidentally detach from the container. Additionally, strengthening the connection between the container and the lid may make assembling and disassembling the lid more difficult. Summary of the Invention

[0010] Therefore, the technical problem of the present invention is to provide a cosmetic container that can more reliably fix the lid to the body of the cosmetic container without compromising the user experience.

[0011] The present invention solves the above-mentioned technical problems by providing a cosmetic container comprising: a container body having an internal space for accommodating cosmetics; a discharge body disposed on the upper part of the container body for discharging cosmetics from inside the container body; and a cover body formed to be attached to the discharge body. The cover body includes a covering body that is inserted into the discharge body while being placed on it. The covering body has a surface along the insertion direction of the discharge body, covering at least a portion of the side surface of the discharge body, and has a protrusion extending from a surface opposite to the side surface of the inserted discharge body towards the side surface. The protrusion includes a first protrusion and a second protrusion, the first protrusion and the second protrusion being respectively disposed at different positions in the covering body within the insertion direction.

[0012] Here, the first protrusion and the second protrusion may be provided in multiple mutually separated regions in the cover, and a recess is provided between the multiple regions, which is recessed from the end of the insertion side of the discharge body toward the insertion direction.

[0013] Alternatively, multiple recesses may be formed intermittently along the circumference of the opening into which the discharge body is inserted.

[0014] Alternatively, the first protrusion may be provided along the end of the discharge body on the insertion side in the cover, and the second protrusion may be provided at a position further inward in the insertion direction than the first protrusion.

[0015] Alternatively, the first protrusion and the second protrusion may be formed to extend in a direction orthogonal to the insertion direction.

[0016] Alternatively, the first protrusion and the second protrusion may be formed at positions that do not overlap in a direction orthogonal to the insertion direction.

[0017] Alternatively, the first protrusion may be formed such that the protrusion height of the first protrusion from the inner peripheral surface of the cover is greater than the protrusion height of the second protrusion.

[0018] Alternatively, the cover may have a top wall and a peripheral wall continuously disposed therefrom, and the protrusion is disposed on the surface of the peripheral wall opposite to the side of the inserted discharge body.

[0019] Alternatively, the cover may include: an inner body having a top wall and a peripheral wall continuously disposed therefrom; and an outer body configured to cover the outer surfaces of the top wall and the peripheral wall.

[0020] Alternatively, the outer casing may have an outer peripheral wall that covers the peripheral wall of the inner casing, the outer peripheral wall being formed to protrude toward the container body side than the peripheral wall.

[0021] Alternatively, as the discharge body is inserted into the cover, at least a portion of the protrusion slides against the side of the discharge body, and when the cover is attached to the discharge body, at least a portion of the protrusion is locked at the bottom end of the discharge body.

[0022] Alternatively, as the discharge body is inserted into the cover, either the first protrusion or the second protrusion may be periodically engaged at the bottom end of the discharge body.

[0023] Moreover, the present invention is a cosmetic product comprising the cosmetic container and cosmetic material contained within the cosmetic container.

[0037] Hereinafter, embodiments of the cosmetic container of the present invention will be specifically described based on the accompanying drawings. It should be noted that the present invention is not limited to these embodiments.

[0038] <Overall composition of cosmetic container 100>

[0039] Figure 1 This is a perspective view of the cosmetic container 100 according to this embodiment. Figure 1As shown, the cosmetic container 100 of this embodiment includes: a container body 300 for containing cosmetics; a discharge body 500 disposed on the upper part of the container body 300; and a cover 700 that can be attached to cover the discharge body 500.

[0040] It should be noted that, in the following description, the upper and lower sides of the cosmetic container 100 in this embodiment are respectively based on... Figure 1 , Figure 2 The direction of the arrow shown is... Figure 1 , Figure 2 The vertical direction is defined within it.

[0041] <Container Body 300>

[0042] Figure 2 This is a partial end view showing a section of the cap 700 with the cap 700 attached to the cosmetic container 100 of this embodiment. Hereinafter, refer to... Figure 1 and Figure 2 The composition of the container body 300 is described.

[0043] The container body 300 includes: a main body 301 that can contain cosmetics; and a neck 309 that is continuously disposed from the upper end of the main body 301 and can be fitted with an exhaust body 500. The main body 301 includes: a peripheral wall 311 that is formed in a cylindrical shape; and a bottom wall 313 that is provided to cover the lower end side of the peripheral wall 311.

[0044] The neck 309 is cylindrical and is connected to the upper end of the peripheral wall 311 via a shoulder portion (described later). The neck 309 is a portion whose radial dimension is smaller than that of the main body 301. Furthermore, in this embodiment, the outer peripheral surface of the neck 309 is provided with an external thread portion 315 for assembling the discharge body 500.

[0045] A step is provided between the main body 301 and the neck 309. Specifically, a first shoulder 303 and a second shoulder 305 are provided in two sections between the main body 301 and the neck 309. The first shoulder 303 bends inward from the upper end of the peripheral wall 311, forming a generally horizontal surface. Furthermore, the first shoulder 303 is connected to a step 307, which rises from the inner end of the first shoulder 303.

[0046] Furthermore, the second shoulder 305 bends inward from the upper end of the step 307 to form a gently rising sloping surface, and is continuous with the lower end of the neck 309.

[0047] <Excreted 500>

[0048] A discharge body 500 for discharging cosmetics contained in the container body 300 is fitted at the neck 309. In this embodiment, the discharge body 500 is composed of a pump unit, which includes: a cylindrical base 53 formed to be attached to the neck 309 of the container body 300; and a pressing body 51 formed to be pressed down relative to the base 53. The pressing body 51 has a nozzle-shaped discharge port 55, and by pressing the pressing body 51 relative to the base 53, the contents of the container body 300 can be discharged from the discharge port 55.

[0049] It should be noted that the discharge body 500 in this embodiment is formed by a pump unit, but it is not limited to any pump unit as long as it has the function of discharging cosmetic contents. For example, the discharge body 500 may also be a sprayer or a cap that has a hole for discharging liquid cosmetic and is formed to seal the opening 310 of the neck 309.

[0050] <Cover 700>

[0051] In this embodiment, the cap 700 is formed to be attached to a part of the cosmetic container 100, specifically to the discharge body 500. The method of attaching the cap 700 will be described in detail later, but it is basically attached to the discharge body 500 by inserting the discharge body 500 into the cap 700.

[0052] The cover 700 of this embodiment is composed of a plurality of components that overlap in the vertical direction. Specifically, the cover 700 includes: a cover body 1, a cover discharge body 500; and an outer body 7, which is configured to cover the outer side of the cover body 1.

[0053] <Cover 1>

[0054] Figure 3 (a) is a top view of cover 1. Figure 3 (b) is the front view of the cover 1. Figure 3 (c) is a bottom view of the cover 1. Figure 3 (d) is Figure 3 (c) IIID-IIID sectional view. See below for reference. Figure 3 (a) to Figure 3 (d) describes the structure of the covering 1.

[0055] The cover 1 is formed in the shape of a cap into which the discharge body 500 can be inserted. In other words, the cover 1 can accommodate the discharge body 500. In this embodiment, the cover 1 is formed to cover at least a portion of the side of the discharge body 500 when the discharge body 500 is accommodated. More specifically, the cover 1 includes: a top wall 11; and a cylindrical peripheral wall 13, which is connected to the peripheral edge of the top wall 11 and extends downward. The top wall 11 and the peripheral wall 13 form a space portion 103 that can accommodate the discharge body 500. Furthermore, an opening 101 is provided at the end of the peripheral wall 13 on the side opposite to the top wall 11, through which the discharge body 500 can be inserted into the space portion 103.

[0056] Regarding the cover 1 of this embodiment, the inner circumferential surface of the peripheral wall 13 is formed into a cylindrical shape along the insertion direction of the discharge body 500, and the inner diameter of the cover 1 is formed to be approximately the same as the outer diameter of the base 53 of the discharge body 500. That is, the cover 1 is formed with dimensions that allow the discharge body 500 inserted into it to slide.

[0057] On the other hand, the external shape of the cover 1 is formed by four sides through the peripheral wall 13, which form a deformed rectangle when viewed from above. More specifically, the radial thickness of the peripheral wall 13 is locally different, with the thickest part forming a corner 131 that protrudes beyond the others. Thus, by forming the external shape of the cover 1 as a deformed rectangle, it is easy to retain. Furthermore, by setting the external shape of the cover 1 as a deformed rectangle, the front and back sides have different shapes, so that the front of the cosmetic container 100 can be identified even when the cover 700 is attached.

[0058] Furthermore, a groove 135 is provided on the outer peripheral surface of the peripheral wall 13, extending longitudinally and recessed inward from the outer peripheral surface. By providing multiple such grooves 135, the cover body 700 can be made lighter, and the cost of raw materials can be reduced.

[0059] <Zhoubi 15>

[0060] A peripheral wall 15 is provided at the lower end 133 of the peripheral wall 13. In this embodiment, the peripheral wall 15 is formed as a thin plate-like portion protruding downward from the lower end 133. Furthermore, the peripheral wall 15 is formed in a curved manner along the circumferential direction of the opening 101. Moreover, its inner peripheral surface is formed to be continuous with the inner peripheral surface of the peripheral wall 13 without any steps. That is, the inner peripheral surface of the peripheral wall 15 is flush with the inner peripheral surface of the peripheral wall 13.

[0061] Furthermore, a recess 17 is formed by cutting off a portion of the circumferential direction of the peripheral wall 15. That is, three recesses 17 are formed at equal intervals in the circumferential direction by interrupting the continuity of the circumferential direction of the peripheral wall 15.

[0062] In this embodiment, three peripheral walls 15 are provided at equal intervals in the circumferential direction, spaced apart from the recess 17. That is, adjacent peripheral walls 15 are positioned at an angle of 120° to each other when viewed from the center of the opening 101. In this way, by providing three peripheral walls 15 at equal intervals in the circumferential direction, the discharge body 500 can be held in three directions, and the cover 700 can be fixed more reliably.

[0063] Furthermore, by utilizing the recess 17 to interrupt the circumferential continuity of the peripheral wall 15, the peripheral wall 15 can bend radially, and the first protrusion 153 and the second protrusion 155, described later, can be used to hold the base 53 in stages.

[0064] like Figure 3 As shown in (d), the recess 17 in this embodiment is formed as a generally rectangular notch. Consequently, the shape of the peripheral wall 15 sandwiched between the recess 17 is also generally rectangular. Regarding the dimensions of the recess 17, its circumferential length L4 can be arbitrarily determined, but preferably, this length L4 is formed such that the relative ratio of L4 to L3 in the relationship between the circumferential length L4 of the recess 17 and the circumferential length L3 of the peripheral wall 15 is in the range of 1:3 to 3:1. More preferably, the length L4 is formed such that the ratio of L4 to L3 is approximately 1:1. Furthermore, the depth D1 in the insertion direction of the recess 17 can be arbitrarily determined, but preferably, this depth D1 is formed in the range of D1 ≥ W2 + W3.

[0065] By forming the recess 17 within the above range, the strength of the peripheral wall 15 can be ensured, and the discharge body 500 can be stably maintained.

[0066] It should be noted that it is preferable that the inner corner 171 of the recess 17 is not a right angle but a continuous arc. This will improve the strength of the peripheral wall 15.

[0067] Furthermore, the two corners 152 of the peripheral wall 15 are also preferably chamfered to form a rounded shape. This allows for smooth insertion of the discharge body 500. Moreover, the peripheral wall 15 is formed such that, compared to its tip side, its circumferential length L3 is longer at the root side. This widens the width of the peripheral wall 15 at the root side, further increasing its rigidity. Consequently, the insertion sensation gradually tightens as the discharge body 500 is inserted. As a result, insertion of the discharge body 500 is easy at the beginning, and it can be reliably secured after insertion.

[0068] <First convex portion 153, second convex portion 155>

[0069] Figure 4 (a) is a view showing the peripheral wall 15 of this embodiment from the inside of the opening 101. Figure 4 (b) is Figure 4 (a) IVB-IVB sectional view, Figure 4 (c) is Figure 4 (a) IVC-IVC sectional view, Figure 4 (d) is a diagram showing the peripheral wall 15 from the top 157 side. See below for reference. Figure 4 (a) ~ Figure 4 (d) provides a detailed description of the design for the protrusion located on the peripheral wall 15.

[0070] On the inner surface 151 of the peripheral wall 15, a protrusion is provided such that it protrudes toward the side 531 of the base 53 when the cover 700 is attached to the discharge body 500. This protrusion consists of a first protrusion 153 and a second protrusion 155. In this embodiment, a first protrusion 153 and a second protrusion 155 are respectively provided in the region of a peripheral wall 15 sandwiched between two adjacent recesses 17. In other words, the recesses 17 are located between the regions of the plurality of peripheral walls 15 provided with the first protrusion 153 and the second protrusion 155.

[0071] The first protrusion 153 is formed as a ridge extending along the top end 157 of the peripheral wall 15. In addition, the second protrusion 155 is formed as a ridge extending in the circumferential direction with a predetermined interval (W3) between it and the top end 157 of the peripheral wall 15.

[0072] Thus, the first protrusion 153 is located closer to the top end 157 of the peripheral wall 15 than the second protrusion 155. In other words, the first protrusion 153 and the second protrusion 155 are located at different positions in the insertion direction of the discharge body 500. It should be noted that, here, "circumferential" refers to the direction orthogonal to the direction of insertion into the discharge body 500, and "radial" refers to the radial direction of the opening 101. Furthermore, hereinafter, the insertion direction of the discharge body 500 will sometimes be simply referred to as the "insertion direction".

[0073] As described above, the first protrusion 153 and the second protrusion 155 are located at different positions in the insertion direction, but in this embodiment, a portion of them overlaps in the insertion direction. That is, the width W1 of the first protrusion 153 in the insertion direction is formed to be wider than the distance W3 between the second protrusion 155 and the top end portion 157 of the peripheral wall 15. As a result, there is a region A where a portion of the first protrusion 153 and a portion of the second protrusion 155 overlap in the insertion direction.

[0074] Thus, by having a portion of the first protrusion 153 overlap with a portion of the second protrusion 155 in the insertion direction, the phased locking from the first protrusion 153 to the second protrusion 155 will be transferred more smoothly.

[0075] In addition, the first protrusion 153 and the second protrusion 155 are respectively located at different positions in the circumferential direction.

[0076] In detail, the first protrusion 153 extends circumferentially from one side 159a of the peripheral wall 15 by a predetermined length. Similarly, the second protrusion 155 extends circumferentially from the other side 159b of the peripheral wall 15 by a predetermined length. Furthermore, the first protrusion 153 and the second protrusion 155 are formed such that they do not overlap circumferentially at their respective top ends extending from the side portions 159a and 159b of the peripheral wall 15. Thus, by ensuring that the first protrusion 153 and the second protrusion 155 do not overlap circumferentially, they can be locked onto the discharge body 500 without interfering with each other.

[0077] Furthermore, the first protrusion 153 and the second protrusion 155 are formed continuously in the circumferential direction. That is, the first protrusion 153 and the second protrusion 155 are formed continuously on the top side extending from the side portions 159a and 159b of the peripheral wall 15, respectively, without any gaps in the circumferential direction. In this way, by continuously forming the first protrusion 153 and the second protrusion 155 in the circumferential direction, the first protrusion 153 and the second protrusion 155 can be provided over a wider range. As a result, the locking and supporting effect achieved by the first protrusion 153 and the second protrusion 155 can be further improved.

[0078] Here, the circumferential length L2 of the first protrusion 153 and the circumferential length L1 of the second protrusion 155 are configured such that L1 + L2 ≤ L3 with respect to the circumferential length L3 of the peripheral wall 15.

[0079] That is, the length of the sum of the circumferential lengths of the first protrusion 153 and the second protrusion 155 is formed to be the same as or shorter than the circumferential length of the peripheral wall 15.

[0080] In this embodiment, the circumferential length L2 of the first protrusion 153 and the circumferential length L1 of the second protrusion 155 are formed to be approximately the same. Thus, by making the circumferential length L2 of the first protrusion 153 and the circumferential length L1 of the second protrusion 155 approximately the same, the first protrusion 153 can reliably lock the object, and the second protrusion 155 can reliably support it.

[0081] In this embodiment, the width W1 of the first protrusion 153 in the insertion direction and the width W2 of the second protrusion 155 are configured such that W1 < W2.

[0082] Thus, by making the width W2 of the second protrusion 155 wider than the width W1 of the first protrusion 153 in the insertion direction, the second protrusion 155 can reliably support itself even if its position shifts in the vertical direction while the first protrusion 153 is locked.

[0083] In this embodiment, the radial protrusion height H1 of the first protrusion 153 and the protrusion height H2 of the second protrusion 155 are formed such that H1 > H2.

[0084] Thus, by setting the radial protrusion height H1 of the first protrusion 153 to be higher than the protrusion height H2 of the second protrusion 155, the first protrusion 153 and the second protrusion 155 can be locked in stages onto the base 53 of the discharge body 500.

[0085] In this embodiment, the cross-sectional shape of the first protrusion 153 and the second protrusion 155 is generally mountain-shaped. Specifically, the protrusion height of the first protrusion 153 gradually decreases from its most prominent top 1531 to its inner side surface 151 or top end 157. That is, the slope 1533 is formed in a conical shape. Similarly, the slope 1553 is also formed in a conical shape such that the protrusion height of the second protrusion 155 gradually decreases from its most prominent top 1551.

[0086] Thus, with the first protrusion 153 and the second protrusion 155 having conical inclined surfaces 1533 and 1553, the locking and unlocking of the cover 700 to the container body 300 becomes smooth. It should be noted that the cross-sectional shape of the first protrusion 153 and the second protrusion 155 is not limited to this, and can also be semi-circular, semi-elliptical, triangular, quadrilateral, trapezoidal, or other polygonal shapes. However, in order to smoothly insert the discharge body 500, it is preferable that the tops 1531 and 1551 that connect with the base 53 of the discharge body 500 have rounded corners.

[0087] <Exterior body 7>

[0088] Figure 5 This is a perspective view of the cover 700 as seen from the opening 101 side. (See image below.) Figure 5 and Figure 1 As shown, the outer casing 7 includes: an outer top wall 71, configured to cover the outer side of the top wall 11 of the cover 1; and an outer peripheral wall 73, configured to cover the outer side of the peripheral wall 13 of the cover 1. Both the outer top wall 71 and the outer peripheral wall 73 are formed as plates of approximately the same thickness, thus the outer casing 7 is formed to generally follow the shape of the cover 1. Furthermore, in this embodiment, the outer casing 7 is formed to have a shape approximately the same as the container body 300.

[0089] like Figure 2 As shown, a groove-shaped recess 733 is formed circumferentially on the inner circumferential surface 731 of the outer peripheral wall 73. A protrusion 137 of the peripheral wall 13 of the cover 1 is inserted into this recess 733, thereby securing the cover 1 in a state assembled within the outer body 7. It should be noted that the method of fixing the outer body 7 to the cover 1 is not limited to this; other fixing methods, such as adhesive bonding, can also be used.

[0090] The outer peripheral wall 73 of the outer body 7 is formed to cover the entire peripheral wall 13 of the cover 1, and protrudes further toward the container body 300 than the peripheral wall 15 (see reference). Figure 5 Furthermore, in this embodiment, the cover 700 is configured such that, when attached to the discharge body 500, the lower end 735 of the outer peripheral wall 73 abuts against the first shoulder 303 of the container body 300 (see reference). Figure 2 ).

[0091] Thus, by providing the outer casing 7 to cover the outer side of the peripheral wall 13 of the casing 1, the recess 17 formed on the peripheral wall 15 of the casing 1 is not easily visible from the outside, and it also gives a clean and neat impression in terms of appearance. Moreover, since the outer peripheral wall 73 of the outer casing 7 is formed to protrude towards the container body 300 from the peripheral wall 15, in the event that the casing 700 is accidentally dropped, the peripheral wall 15 will not directly hit the ground, thus preventing damage to the peripheral wall 15.

[0092] <Assembly method for cover 700>

[0093] Figure 6 (a) to Figure 6 (e) is a diagram schematically showing the relative positional relationship between the peripheral wall 15 and the base 53 when the cover 700 is attached to the discharge body 500.

[0094] Figure 6 (a) indicates the state before the cover 700 is attached to the discharge body 500. As shown, in the state before the discharge body 500 is inserted into the cover 700, the first protrusion 153 is located radially inside the side 531 of the base 53.

[0095] Figure 6 (b) indicates the state shortly after the cap 700 is assembled, that is, the state in which the insertion of the discharge body 500 begins from the opening 101 of the cap 700. In this state, the upper end 537 of the base 53 and the corner 539 of the side surface 531 abut against the inclined surface 1533 of the first protrusion 153. Furthermore, when the discharge body 500 is inserted in this state, the peripheral wall 15 moves in the direction of arrow F1. At this time, the corner 539 of the base 53 slides towards the top 1531 of the first protrusion 153 while abutting against the inclined surface 1533 of the first protrusion 153. As a result, stress is applied to the peripheral wall 15 in the direction of arrow F2 away from the side surface 531, in the form of the first protrusion 153 being pressed against the corner 539. As a result, the peripheral wall 15 tilts radially outward and expands from its top end 157 side.

[0096] Figure 6(c) indicates a state where the discharge body 500 has been further inserted. In this state, the first protrusion 153 and the second protrusion 155 are moving toward a position opposite to the side surface 531, with the top 1531 of the first protrusion 153 abutting against the side surface 531 of the base 53 of the discharge body 500. At this time, stress is applied to the peripheral wall 15 in the direction of arrow F2 away from the side surface 531, in the form of the first protrusion 153 being pressed against the side surface 531. Furthermore, since the peripheral wall 15 has a certain degree of flexibility, it acts with a force that counteracts the stress in the direction away from the side surface 531, thereby placing the first protrusion 153 in a state where it is pressed against the side surface 531 by a certain force.

[0097] Furthermore, regarding the second protrusion 155, whose protrusion height is lower than that of the first protrusion 153, its top 1551 does not abut against the side 531 of the base 53 but forms a gap GP, and the second protrusion 155 is in a state of suspension relative to the side 531.

[0098] When from Figure 6 When the discharge body 500 is further inserted in state (c), the top 1531 of the first protrusion 153 reaches the bottom end 533 of the base 53. Furthermore, as... Figure 6 As shown in (d), when the top 1531 moves to the lower side past the bottom end 533 of the base 53, the corner 535 of the side 531 and the bottom end 533 abuts against the inclined surface 1533 of the first protrusion 153 while sliding towards the inner side 151 of the peripheral wall 15. Thus, as the corner 535 slides on the inclined surface 1533, the gap between the peripheral wall 15 and the side 531 narrows, and the top 1551 of the second protrusion 155 abuts against the side 531.

[0099] At this time, the entire peripheral wall 15 is in a state of wanting to return to the side 531, so the top 1551 of the second protrusion 155 is also pressed against the side 531 by a certain force.

[0100] exist Figure 6 In state (d), the first protrusion 153 is engaged with the corner 535 of the base 53. Furthermore, the top 1551 of the second protrusion 155 is pressed against the side 531 by a certain force and is in a state where the side 531 is held in place from three directions.

[0101] It should be noted that, in this state, such as Figure 2 As shown, the lower end 735 of the outer peripheral wall 73 of the outer casing 7 abuts against the first shoulder 303 of the container body 300. Therefore, the cover 700 will not... Figure 6The state of (d) moves further downward, but is fixed at that position. In addition, the cover 700 can be attached to the container body 300 with almost no gap between the cover 700 and the container body 300.

[0102] Furthermore, when the assembly of the discharge body 500 relative to the neck 309 is insufficient during manufacturing, the gap between the bottom end 533 of the base 53 and the second shoulder 305 of the container body 300 (see reference) Figure 2 The so-called "shoulder gap" is sometimes wider than the width intended in the design. In such cases, because the base 53 is suspended relative to its original position, even when it is in a state of suspension, the shoulder gap is wider than the width intended in the design. Figure 6 In the state of (d), the lower end 735 of the outer peripheral wall 73 sometimes does not abut against the first shoulder 303 of the container body 300.

[0103] In this situation, from Figure 6 The state of (d) is further processed by inserting the discharge body 500 into the cover body 700. Thus, as Figure 6 As shown in (e), the top 1551 of the second protrusion 155 moves to the lower side, passing over the bottom end 533 of the base 53. As a result, the corner 535 of the side 531 and the bottom end 533 slides toward the inner side 151 of the peripheral wall 15 while abutting against the inclined surface 1553 of the second protrusion 155.

[0104] Furthermore, when the lower end 735 of the outer peripheral wall 73 of the outer casing 7 abuts against the first shoulder 303 of the container body 300, the cover 700 is attached to the discharge body 500. In this state, the corner 535 is locked onto any part of the inclined surface 1553 of the second protrusion 155 by being pressed with a certain force.

[0105] From Figure 6 (d) or Figure 6 When the cover 700 is removed from the locked state (e), simply pull the cover 700 away from the container body 300. Thus, the first protrusion 153 and the second protrusion 155 sequentially emerge from... Figure 6 (d) towards Figure 6 The state of (c) or from Figure 6 (e) towards Figure 6 The state transition of (c) occurs simultaneously with the release of the locking of the cover 700 relative to the discharge body 500.

[0106] As described above, according to this embodiment, the cover 700 can be engaged with the discharge body 500 in stages by either the first protrusion 153 or the second protrusion 155, regardless of the deviation in the gap between the bottom end portion 533 of the base 53 and the second shoulder portion 305 of the container body 300. In other words, when the gap between the bottom end portion 533 of the base 53 and the second shoulder portion 305 of the container body 300 is narrow, the first protrusion 153 can be used to engage the discharge body 500; when the gap between the bottom end portion 533 and the second shoulder portion 305 is wide, the second protrusion 155 can be used for engagement.

[0107] Furthermore, by providing tapered inclined surfaces 1533 and 1553 for the first protrusion 153 and the second protrusion 155, a smooth operating feel can be obtained without any jamming during the series of operations from locking the first protrusion 153 or the second protrusion 155 to releasing it from the discharge body 500. Moreover, it avoids the impact sound of stepping over a step, as seen in comparative examples that differ from this embodiment, where locking and releasing require stepping over a certain height, thus providing a more sophisticated impression.

[0108] In the cosmetic container 100 of this embodiment, the raw materials of any one of the container body 300, the discharge body 500 and the cover 700 are not particularly limited, and synthetic resins such as polyethylene and polypropylene can be preferably used. In particular, the cover 1 having the peripheral wall 15 is preferably formed of a synthetic resin with a certain degree of flexibility.

[0109] <Variation Example 1>

[0110] Figure 7 (a) is a diagram showing the peripheral wall 1015 of modified example 1 from the inside of the opening 101. Figure 7 (b) is a side view of the peripheral wall 1015 of this modified example 1. As shown in the figure, the peripheral wall 1015 of the modified example 1 is provided such that the first protrusion 1153 and the second protrusion 1155 are spaced apart from each other by a predetermined interval in the insertion direction.

[0111] Thus, by leaving a predetermined gap between the first protrusion 1153 and the second protrusion 1155 in the insertion direction, a more reliable locking can be achieved even when there is a wider gap between the bottom end 533 of the base 53 and the second shoulder 305 of the container body 300.

[0112] Furthermore, in Modified Example 1, the peripheral wall 1015 is provided such that the first protrusion 1153 and the second protrusion 1155 are spaced apart from each other by a predetermined interval in the circumferential direction. In addition, both the first protrusion 1153 and the second protrusion 1155 are provided to be spaced apart from the side portion 1159 of the peripheral wall 1015 by a predetermined interval.

[0113] Thus, by providing a gap between the first protrusion 1153 and the second protrusion 1155 in the circumferential direction, and also providing a gap between the first protrusion 1153 and the side portion 1159 of the peripheral wall 1015, the contact portion between the first protrusion 1153 and the second protrusion 1155 and the base 53 can be reduced, and the sliding resistance between the first protrusion 1153 and the second protrusion 1155 and the base 53 when assembling the cover 700 can be reduced.

[0114] <Variation Example 2>

[0115] Figure 7 (c) is a diagram showing the peripheral wall 2015 of deformation example 2 from the inside of the opening 101. Figure 7 Figure (d) is a side view of the peripheral wall 2015 of this modified example 2. As shown, the second protrusion 2155 of the peripheral wall 2015 of modified example 2 is not a protruding strip, but its cross-sectional shape is formed as a roughly semi-circular protrusion. Three of these second protrusions 2155 are provided at predetermined intervals.

[0116] Thus, by making the second protrusion 2155 protruding and providing multiple such second protrusions 2155, the sliding resistance between the first protrusion 2153 and the second protrusion 2155 and the base 53 during assembly of the cover 700 can be reduced.

[0117] <Variation Example 3>

[0118] Figure 8 Figure (a) shows the peripheral wall 3015 of Modified Example 3 from the inside of the opening 101. The peripheral wall 3015 of Modified Example 3 does not have a recess 17, but is formed continuously in a ring shape in the circumferential direction. In this peripheral wall 3015, the first protrusion 3153 and the second protrusion 3155 are located at different positions in the insertion direction. Thus, since the lower end of the peripheral wall 3015 is flush, the possibility of breakage at the lower end is reduced, and the appearance is clean and neat; therefore, the outer casing 7 is not required.

[0119] <Variation Example 4>

[0120] Figure 8 (b) is a view showing the peripheral wall 4015 of Modified Example 4 from the inside of the opening 101. The peripheral wall 4015 of Modified Example 4 is formed to have only the first protrusion 4153. In this way, the structure is simplified, thereby reducing manufacturing costs.

[0121] <Variation Example 5>

[0122] Figure 9This is a diagram showing the cover 1700 of Modified Example 5 from the opening 101 side. The cover 1700 of Modified Example 5 is composed of a cover 110 without an outer body 7. A recess 17 is provided at the lower end of the peripheral wall 173 of the cover 110, and a first protrusion 153 and a second protrusion 155 protruding inward are provided on the peripheral wall 15 portion between the recesses 17.

[0123] The scheme of not setting the outer body 7, such as the cover 1700 of Modified Example 5, can make the cover 1700 lighter and further reduce manufacturing costs.

[0124] Various implementation methods and modifications have been described above, but of course these implementation methods and modifications can also be combined with each other to form a configuration.

[0125] Furthermore, this disclosure is not limited to any of the above-described embodiments and may be implemented in various ways without departing from the spirit of this disclosure.
