MODE FOR CARRYING OUT THE INVENTION

[0009] Hereinafter, embodiments of the cosmetic container of the present invention will be specifically described based on the drawings. Note that the present invention is not limited to these embodiments at all.

[0010] <Overall Configuration of Cosmetic Container 100> FIG. 1 is a perspective view of the cosmetic container 100 of this embodiment. As shown in FIG. 1, the cosmetic container 100 of this embodiment includes a container body 300 for storing cosmetics, a discharge body 500 provided on the upper part of the container body 300, and a lid body 700 that can be attached so as to cover the discharge body 500. In the following description, the upper side and the lower side of the cosmetic container 100 of this embodiment are respectively defined by the directions of the arrows shown in FIGS. 1 and 2, that is, the vertical directions in FIGS. 1 and 2.

[0011] <Container Body 300> FIG. 2 is a partial end view showing a state where the lid body 700 is attached to the cosmetic container 100 of the present embodiment with a part of the lid body 700 cut away. Hereinafter, the configuration of the container body 300 will be described with reference to FIGS. 1 and 2. The container body 300 includes a body portion 301 capable of accommodating cosmetics therein, and a neck portion 309 provided continuously at the upper end of the body portion 301 to which the discharge body 500 can be attached. Among these, the body portion 301 includes a peripheral wall 311 formed in a cylindrical shape and a bottom wall 313 provided so as to cover the lower end side of the peripheral wall 311.

[0012] The neck portion 309 is formed in a cylindrical shape and is provided so as to be continuous with the upper end side of the peripheral wall 311 via a shoulder portion described later. This neck portion 309 is a portion where the dimension in the radial direction is smaller than that of the body portion 301. And, a male screw portion 315 for attaching the discharge body 500 is provided on the outer peripheral surface of the neck portion 309 of the present embodiment.

[0013] A step is provided between the body portion 301 and the neck portion 309. That is, a first shoulder portion 303 and a second shoulder portion 305 are provided in two steps between the body portion 301 and the neck portion 309. Among these, the first shoulder portion 303 bends inward from the upper end portion of the peripheral wall 311 to form a substantially horizontal surface. And it is formed so as to be continuous with a step portion 307 formed so as to rise from the inner end portion of the first shoulder portion 303. Further, the second shoulder portion 305 bends inward from the upper end portion of the step portion 307 to form an inclined surface that gently rises, and is continuous with the lower end portion of the neck portion 309.

[0014] <Discharge body 500> A dispensing body 500 for dispensing the cosmetic product contained in the container body 300 is attached to the neck portion 309. The dispensing body 500 in this embodiment is composed of a pump unit comprising a cylindrical base 53 formed to be attachable to the neck portion 309 of the container body 300, and a pressing body 51 formed to be pressable down relative to the base 53. The pressing body 51 is provided with a nozzle-shaped discharge port 55, and by pressing the pressing body 51 down relative to the base 53, the contents of the container body 300 can be discharged from the discharge port 55. In this embodiment, the dispensing body 500 is formed by a pump unit, but it is not limited to such a pump unit as long as it has the function of dispensing the cosmetic contents. For example, the dispensing body 500 may be a spray, or it may be a cap with a hole that can dispense liquid cosmetic and is formed to seal the opening 310 of the neck portion 309.

[0015] <Lid 700> The lid 700 of this embodiment is formed to be attachable to a part of the cosmetic container 100, specifically to the dispensing element 500. The method of attaching the lid 700 will be described in detail later, but basically, it is attached to the dispensing element 500 by inserting the dispensing element 500 into the lid 700. The lid 700 of this embodiment is composed of multiple members stacked in the vertical direction. Specifically, the lid 700 comprises a cover body 1 that covers the discharge body 500 and an outer casing body 7 provided to cover the outer surface of the cover body 1.

[0016] <Cover 1> Figure 3(a) is a plan view of the cover 1, Figure 3(b) is a front view thereof, Figure 3(c) is a bottom view thereof, and Figure 3(d) is an IIID-IIID cross-sectional view of Figure 3(c). The configuration of the cover 1 will be described below with reference to Figures 3(a) to (d). 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 is capable of housing the discharge body 500. In this embodiment, the cover 1 is formed to cover at least a portion of the side surface of the discharge body 500 when the discharge body 500 is housed inside. More specifically, the cover 1 comprises a top wall 11 and a cylindrical peripheral wall 13 that extends downward from the peripheral edge of the top wall 11. The top wall 11 and the peripheral wall 13 form a space 103 into which the discharge body 500 can be housed. An opening 101 is provided at the end of the peripheral wall 13 opposite to the top wall 11, and the discharge body 500 can be inserted into the space 103 through this opening 101.

[0017] In this embodiment, the cover 1 has an inner circumferential surface of the peripheral wall 13 formed in a cylindrical shape along the insertion direction of the discharge body 500, and its inner diameter is formed to be approximately the same as the outer diameter of the base body 53 of the discharge body 500. In other words, the cover 1 is formed to a size that allows the discharge body 500 inserted inside to slide. On the other hand, the external shape of the cover 1 is composed of four sides formed by the peripheral walls 13, and is formed as a deformed rectangle in plan view. More specifically, the radial thickness of the peripheral walls 13 is formed to differ in parts, and the thickest part forms a corner 131 that protrudes from the other parts. By forming the external shape of the cover 1 as a deformed rectangle in this way, it becomes easier to hold. In addition, by making the external shape of the cover 1 a deformed rectangle, the shape of the front side and the back side are different, so the front of the cosmetic container 100 can be recognized even when the lid 700 is attached.

[0018] Furthermore, grooves 135 are provided on the outer surface of the peripheral wall 13, extending vertically inward from the outer surface. By providing multiple such grooves 135, the weight of the lid 700 can be reduced, and the cost of raw materials can be lowered.

[0019] <Peripheral wall 15> A peripheral wall 15 is provided at the lower end 133 of the peripheral wall 13. In this embodiment, the peripheral wall 15 is a thin plate-like portion that protrudes downward from the lower end 133. Furthermore, the peripheral wall 15 is formed in a curved shape so as to follow the circumferential direction of the opening 101. Its inner circumferential surface is formed to be continuous with the inner circumferential surface of the peripheral wall 13 without any step difference. In other words, the inner circumferential surface of the peripheral wall 15 and the inner circumferential surface of the peripheral wall 13 are aligned. Furthermore, recesses 17 are formed by cutting out a portion of the circumferential wall 15 in the circumferential direction. Specifically, three recesses 17 are formed at equal intervals in the circumferential direction, so as to interrupt the circumferential continuity of the circumferential wall 15.

[0020] In this embodiment, the peripheral wall 15 is provided in three locations at equal intervals in the circumferential direction, with the recess 17 in between. 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. By providing the peripheral wall 15 in three locations at equal intervals in the circumferential direction in this way, the discharge body 500 can be held from three directions, and the lid 700 can be fixed more securely. Furthermore, by interrupting the circumferential continuity of the peripheral wall 15 with the recess 17, the peripheral wall 15 becomes capable of bending in the radial direction, enabling the base body 53 to be held in stages by the first protrusion 153 and the second protrusion 155, which will be described later.

[0021] As shown in Figure 3(d), the recess 17 in this embodiment is formed in the shape of a roughly rectangular cutout. As a result, the shape of the peripheral wall 15 sandwiched by the recess 17 is also roughly rectangular. Regarding the dimensions of the recess 17, its length L4 in the circumferential direction can be determined arbitrarily, but it is preferable that the relative ratio of the circumferential length L4 of the recess 17 to the circumferential length L3 of the peripheral wall 15 be in the range of 1:3 to 3:1, and it is more preferable that the ratio of L4 to L3 be approximately 1:1. In addition, the depth D1 of the recess 17 in the insertion direction can be determined arbitrarily, but it is preferable that it be formed in the range of D1 ≥ W2 + W3. By forming the recess 17 within the above range, the discharge body 500 can be held stably while ensuring the strength of the peripheral wall 15.

[0022] Furthermore, the inner corner portion 171 of the recess 17 should be provided in a continuous, rounded shape rather than being perpendicular. This improves the strength of the surrounding wall 15. Furthermore, the corners 152 of the peripheral wall 15 should also be rounded to form an R-shape. This allows for smoother insertion of the discharge body 500. In addition, the peripheral wall 15 is formed such that its circumferential length L3 is longer at the base than at the tip. By forming the peripheral wall 15 wider at the base, the rigidity at the base is increased. As a result, the insertion of the discharge body 500 becomes progressively firmer. Consequently, the discharge body 500 is easy to insert at the start and can be securely fixed after insertion.

[0023] <First protrusion 153, second protrusion 155> Figure 4(a) shows the peripheral wall 15 of this embodiment as seen from the inside of the opening 101, Figure 4(b) is a cross-sectional view of IVB-IVB in Figure 4(a), Figure 4(c) is a cross-sectional view of IVC-IVC in Figure 4(a), and Figure 4(d) shows the peripheral wall 15 as seen from the tip portion 157 side. The characteristics of the protrusions provided on the peripheral wall 15 will be described in detail below with reference to Figures 4(a) to (d). The inner surface 151 of the peripheral wall 15 is provided with a protrusion that projects toward the side surface 531 of the base body 53 when the lid 700 is attached to the discharge body 500. This protrusion is composed of a first protrusion 153 and a second protrusion 155. In this embodiment, one first protrusion 153 and one second protrusion 155 are provided in a region of one peripheral wall 15 sandwiched between two adjacent recesses 17. In other words, recesses 17 are provided between multiple regions of the peripheral wall 15 where the first protrusion 153 and the second protrusion 155 are provided.

[0024] The first protrusion 153 is formed as a single protrusion that extends along the tip 157 of the peripheral wall 15. The second protrusion 155 is also formed as a single protrusion that extends along the circumferential direction, with a predetermined distance (W3) between it and the tip 157 of the peripheral wall 15. Thus, the first protrusion 153 is located closer to the tip 157 of the circumferential wall 15 than the second protrusion 155. In other words, the first protrusion 153 and the second protrusion 155 are located at different positions relative to each other in the insertion direction of the discharge body 500. Here, "circumferential direction" means the direction perpendicular to the direction in which the discharge body 500 is inserted, and "radial direction" means the radial direction in the opening 101. Furthermore, in the following, the insertion direction of the discharge body 500 may simply be referred to as the "insertion direction."

[0025] As described above, the first protrusion 153 and the second protrusion 155 are provided at different positions in the insertion direction, but in this embodiment, parts of them overlap in the insertion direction. That is, the width W1 of the first protrusion 153 in the insertion direction is wider than the distance W3 between the second protrusion 155 and the tip 157 of the peripheral wall 15. As a result, there is a region A in which parts of the first protrusion 153 and parts of the second protrusion 155 overlap in the insertion direction. In this way, the overlap of a portion of the first protrusion 153 and a portion of the second protrusion 155 in the insertion direction allows for a smoother transition in the gradual locking from the first protrusion 153 to the second protrusion 155.

[0026] Furthermore, the first protrusion 153 and the second protrusion 155 are provided at different positions in the circumferential direction. More specifically, the first protrusion 153 is provided to extend circumferentially from one side edge 159a of the peripheral wall 15 for a predetermined length. Similarly, the second protrusion 155 is provided to extend circumferentially from the other side edge 159b of the peripheral wall 15 for a predetermined length. The first protrusion 153 and the second protrusion 155 are formed so as not to overlap circumferentially at the tip ends extending from the side edges 159a and 159b of the peripheral wall 15, respectively. By forming the first protrusion 153 and the second protrusion 155 so as not to overlap circumferentially, the first protrusion 153 and the second protrusion 155 can engage with the discharge body 500 without interfering with each other.

[0027] Furthermore, the first convex portion 153 and the second convex portion 155 are formed continuously in the circumferential direction. That is, the first convex portion 153 and the second convex portion 155 are formed so as to be continuous without providing a gap in the circumferential direction at the tip side extending from the side portions 159a and 159b of the peripheral wall 15, respectively. Thus, by forming the first convex portion 153 and the second convex portion 155 continuously in the circumferential direction, the first convex portion 153 and the second convex portion 155 can be provided in a wider range. As a result, the locking and supporting effects by the first convex portion 153 and the second convex portion 155 can be further improved.

[0028] Here, the circumferential length L2 of the first convex portion 153 and the circumferential length L1 of the second convex portion 155 are formed so as to satisfy the relationship of L1 + L2 ≤ L3 with respect to the circumferential length L3 of the peripheral wall 15. That is, the length obtained by adding the circumferential lengths of the first convex portion 153 and the second convex portion 155 is formed to be the same as or shorter than the circumferential length of the peripheral wall 15.

[0029] In the present embodiment, the circumferential length L2 of the first convex portion 153 and the circumferential length L1 of the second convex portion 155 are formed to be substantially the same length as each other. Thus, by forming the circumferential length L2 of the first convex portion 153 and the circumferential length L1 of the second convex portion 155 to be substantially the same, the first convex portion 153 can reliably lock, and the second convex portion 155 can reliably support.

[0030] In the present embodiment, the width W1 of the first convex portion 153 in the insertion direction and the width W2 of the second convex portion 155 are formed to satisfy the relationship of W1 < W2. Thus, by making the width W2 of the second convex portion 155 wider than the width W1 of the first convex portion 153 in the insertion direction, even if the position is displaced in the vertical direction in the state where the first convex portion 153 is locked, the second convex portion 155 can reliably support.

[0031] The radially protruding height H1 of the first convex portion 153 and the protruding height H2 of the second convex portion 155 in the present embodiment are formed so that H1 > H2. In this way, by setting the radial projection height H1 of the first protrusion 153 higher than the projection height H2 of the second protrusion 155, the first protrusion 153 and the second protrusion 155 can be locked to the base 53 of the discharge body 500 in stages.

[0032] In this embodiment, the first protrusion 153 and the second protrusion 155 have a roughly mountain-shaped cross-section. Specifically, the first protrusion 153 is formed so that its protrusion height gradually decreases from its most protruding apex 1531 towards the inner surface 151 or tip 157. That is, the slope 1533 is formed in a tapered shape. Similarly, the slope 1553 of the second protrusion 155 is formed in a tapered shape so that its protrusion height gradually decreases from its most protruding apex 1551. In this way, the first protrusion 153 and the second protrusion 155 are provided with tapered slopes 1533 and 1553, respectively, which allows the lid 700 to be smoothly locked to and unlocked from the container body 300. The cross-sectional shape of the first protrusion 153 and the second protrusion 155 is not limited to these, and may be semicircular, semielliptical, triangular, quadrilateral, trapezoidal, or other polygonal shapes, but it is preferable that the tops 1531 and 1551 that contact the base 53 of the discharge body 500 have rounded corners to allow for smooth insertion of the discharge body 500.

[0033] <Exterior 7> Figure 5 is a perspective view of the lid 700 as seen from the opening 101 side. As shown in Figures 5 and 1, the outer casing 7 comprises an outer top wall 71 provided to cover the outside of the top wall 11 of the cover body 1, and an outer peripheral wall 73 provided to cover the outside of the peripheral wall 13 of the cover body 1. Both the outer top wall 71 and the outer peripheral wall 73 are formed in the shape of plates of approximately the same thickness, thereby forming the outer casing 7 to conform substantially to the outer shape of the cover body 1. Furthermore, the outer casing 7 in this embodiment is formed to have substantially the same outer shape as the container body 300.

[0034] As shown in Figure 2, a groove-shaped recess 733 is formed on the inner circumferential surface 731 of the outer circumferential wall 73, extending in the circumferential direction. A protrusion 137 provided on the circumferential wall 13 of the cover body 1 is inserted into this recess 733, thereby locking the cover body 1 into the outer casing 7. Note that the method of fixing the outer casing 7 to the cover body 1 is not limited to this, and other fixing methods, such as adhesive bonding, may also be used.

[0035] The outer peripheral wall 73 of the outer casing 7 covers the entire peripheral wall 13 of the cover body 1 and is formed to protrude further toward the container body 300 than the peripheral wall 15 (see Figure 5). In this embodiment, when the lid 700 is attached to the dispensing body 500, the lower end portion 735 of the outer peripheral wall 73 is formed to abut against the first shoulder portion 303 of the container body 300 (see Figure 2).

[0036] In this way, by providing the outer casing 7 so as to cover the outside of the peripheral wall 13 of the cover body 1, the recess 17 formed in the peripheral wall 15 of the cover body 1 becomes less visible from the outside, giving a neat and tidy appearance. Furthermore, since the outer peripheral wall 73 of the outer casing 7 is formed to protrude further toward the container body 300 than the peripheral wall 15, the peripheral wall 15 will not directly hit the floor or other surface if the lid 700 is accidentally dropped, thus preventing damage to the peripheral wall 15.

[0037] <How to attach lid 700> Figures 6(a) to (e) schematically show the relative positional relationship between the peripheral wall 15 and the base 53 when the lid 700 is attached to the discharge body 500. Figure 6(a) shows the state before the lid 700 is attached to the dispensing body 500. As shown in the figure, before the dispensing body 500 is inserted into the lid 700, the first protrusion 153 is located radially inward from the side surface 531 of the base body 53.

[0038] Figure 6(b) shows the state immediately after the installation of the lid 700, that is, the state when the insertion of the discharge body 500 has begun through the opening 101 of the lid 700. In this state, the corner 539 between the upper end 537 and the side surface 531 of the base body 53 is in contact with the slope 1533 of the first protrusion 153. As the insertion of the discharge body 500 continues, the peripheral wall 15 moves in the direction of arrow F1. At this time, with the corner 539 of the base body 53 in contact with the slope 1533 of the first protrusion 153, it slides toward the top 1531 of the first protrusion 153. As a result, stress is applied to the peripheral wall 15 in the direction of arrow F2, which moves away from the side surface 531, as it is pushed by the first protrusion 153 that is in contact with the corner 539. As a result, the peripheral wall 15 tilts radially outward and spreads out from the tip 157 side.

[0039] Figure 6(c) shows the state after further insertion of the discharge body 500. In this state, the first protrusion 153 and the second protrusion 155 have moved to a position facing the side surface 531, and the top 1531 of the first protrusion 153 is in contact with the side surface 531 of the base body 53 of the discharge body 500. At this time, stress is applied to the peripheral wall 15 in the direction of arrow F2, which moves away from the side surface 531 as it is pushed by the first protrusion 153 which is in contact with the side surface 531. Since the peripheral wall 15 has a certain degree of flexibility, a force acts to counteract the stress in the direction away from the side surface 531, and as a result, the first protrusion 153 is pressed against the side surface 531 with a constant force. Furthermore, the second protrusion 155, which has a lower protrusion height than the first protrusion 153, has its top 1551 not in contact with the side surface 531 of the base 53, forming a gap GP and remaining floating above the side surface 531.

[0040] As the insertion of the discharge body 500 is further advanced from the state shown in Figure 6(c), the top 1531 of the first protrusion 153 reaches the bottom end 533 of the base body 53. Then, as shown in Figure 6(d), when the top 1531 moves downward past the bottom end 533 of the base body 53, the corner 535 between the side surface 531 and the bottom end 533 slides toward the inner surface 151 of the peripheral wall 15 while abutting against the inclined surface 1533 of the first protrusion 153. In this way, as the corner 535 slides along the inclined surface 1533, the gap between the peripheral wall 15 and the side surface 531 narrows, and the top 1551 of the second protrusion 155 comes into contact with the side surface 531. At this time, the entire peripheral wall 15 is in a state where it is trying to return to the side surface 531, so the top 1551 of the second protrusion 155 is also pressed against the side surface 531 with a constant force.

[0041] In the state shown in Figure 6(d), the first protrusion 153 is locked to the corner 535 of the base 53. The top 1551 of the second protrusion 155 is pressed against the side surface 531 with a constant force, and the side surface 531 is held in place from three directions. In this state, as shown in Figure 2, the lower end portion 735 of the outer peripheral wall 73 of the outer casing 7 is in contact with the first shoulder portion 303 of the container body 300. As a result, the lid 700 is fixed in this position without moving further downward from the state shown in Figure 6(d), and the lid 700 can be attached with virtually no gap between the lid 700 and the container body 300.

[0042] Incidentally, if the discharge body 500 is not properly attached to the neck portion 309 during manufacturing, the gap between the bottom end portion 533 of the base body 53 and the second shoulder portion 305 of the container body 300 (see Figure 2), the so-called "shoulder gap," may become wider than the width intended in the design. In such cases, the base body 53 will be floating above its original position, and even in the state shown in Figure 6(d), the lower end portion 735 of the outer peripheral wall 73 may not come into contact with the first shoulder portion 303 of the container body 300.

[0043] In such cases, the insertion of the discharge body 500 into the lid 700 is further advanced from the state shown in Figure 6(d). As a result, as shown in Figure 6(e), the top 1551 of the second protrusion 155 moves downward beyond the bottom end 533 of the base 53. Consequently, the corner 535 between the side surface 531 and the bottom end 533 slides toward the inner surface 151 of the peripheral wall 15 while abutting against the slope 1553 of the second protrusion 155. Then, when the lower end portion 735 of the outer peripheral wall 73 of the outer casing 7 comes into contact with the first shoulder portion 303 of the container body 300, the lid 700 is attached to the dispensing body 500. In this state, the corner portion 535 is locked in place by being pressed with a constant force against any part of the inclined surface 1553 of the second protrusion 155.

[0044] To remove the lid 700 from the locked state shown in Figure 6(d) or Figure 6(e), simply pull the lid 700 away from the container body 300. This causes the first protrusion 153 and the second protrusion 155 to sequentially move from the state shown in Figure 6(d) to Figure 6(c), or from Figure 6(e) to Figure 6(c), and simultaneously releases the locking of the lid 700 from the discharge body 500.

[0045] As described above, with the lid 700 of this embodiment, regardless of variations in the gap between the bottom end 533 of the base 53 and the second shoulder 305 of the container body 300, the discharge body 500 can be locked in stages by either the first protrusion 153 or the second protrusion 155. In other words, when the gap between the bottom end 533 of the base 53 and the second shoulder 305 of the container body 300 is narrow, the discharge body 500 can be locked by the first protrusion 153, and when the gap between the bottom end 533 and the second shoulder 305 is wide, the discharge body 500 can be locked by the second protrusion 155.

[0046] Furthermore, since the first protrusion 153 and the second protrusion 155 are equipped with tapered slopes 1533 and 1553, a smooth and snag-free operation can be obtained during a series of operations from locking to releasing the first protrusion 153 or the second protrusion 155 and the discharge body 500. In addition, in comparative examples different from this embodiment, such as those where a step of a certain height is overcome during locking or releasing, no impact noise is generated when overcoming the step, thus giving a more premium impression.

[0047] In this embodiment, the cosmetic container 100 is not limited in terms of the material of the container body 300, the dispensing element 500, or the lid 700, but synthetic resins such as polyethylene and polypropylene can be suitably used, and in particular, the cover 1 with the peripheral wall 15 is preferably made of a synthetic resin having a certain degree of flexibility.

[0048] <Example 1> Figure 7(a) shows the peripheral wall 1015 of Modified Example 1 as seen from the inside of the opening 101, and Figure 7(b) is a side view thereof. As shown in the figures, the peripheral wall 1015 of Modified Example 1 has a first protrusion 1153 and a second protrusion 1155 provided at a predetermined distance from each other in the insertion direction. In this way, by leaving a predetermined distance between the first protrusion 1153 and the second protrusion 1155 in the insertion direction, a secure lock can be achieved even when there is a wider gap between the bottom end 533 of the base 53 and the second shoulder portion 305 of the container body 300.

[0049] Furthermore, in the modified example 1, the circumferential wall 1015 has a first protrusion 1153 and a second protrusion 1155 that are spaced apart from each other in the circumferential direction. In addition, both the first protrusion 1153 and the second protrusion 1155 are spaced apart from the side edge 1159 of the circumferential wall 1015. In this way, by providing a gap between the first protrusion 1153 and the second protrusion 1155 in the circumferential direction, and also between them and the side edge 1159 of the peripheral wall 1015, the contact portion of the first protrusion 1153 and the second protrusion 1155 with the base 53 can be reduced, thereby reducing the sliding resistance between the first protrusion 1153 and the second protrusion 1155 and the base 53 when the lid 700 is attached.

[0050] <Modification 2> Figure 7(c) shows the peripheral wall 2015 of modified example 2 as seen from the inside of the opening 101, and Figure 7(d) is a side view thereof. As shown in the figures, the peripheral wall 2015 of modified example 2 has a second protrusion 2155 which is not a single protrusion but is formed as a projection with a cross-sectional shape that is approximately semicircular. Three such second protrusions 2155 are provided at predetermined intervals from each other. In this way, by providing multiple second protrusions 2155 in a protruding shape, the sliding resistance between the first protrusions 2153 and the second protrusions 2155 and the base 53 when the lid 700 is attached can be reduced.

[0051] <Variation 3> Figure 8(a) shows the peripheral wall 3015 of Modified Example 3 as seen from the inside of the opening 101. The peripheral wall 3015 of Modified Example 3 does not have a recess 17 and is formed in an annular shape continuously in the circumferential direction. The peripheral wall 3015 has a first protrusion 3153 and a second protrusion 3155 provided at different positions in the insertion direction. In this way, the lower end of the peripheral wall 3015 is aligned, which reduces the risk of damage at the lower end and also gives a neater appearance, thus eliminating the need for an outer casing 7.

[0052] <Modification 4> Figure 8(b) shows the peripheral wall 4015 of Modified Example 4 as seen from the inside of the opening 101. The peripheral wall 4015 of Modified Example 4 is formed to have only the first protrusion 4153. By simplifying the structure in this way, manufacturing costs can be reduced.

[0053] <Modification 5> Figure 9 shows the lid 1700 according to Modification 3 as viewed from the opening 101 side. The lid 1700 of Modification 3 is composed of a cover 110 without an outer casing 7. A recess 17 is provided at the lower end of the peripheral wall 173 of the cover 110, and a first convex portion 153 and a second convex portion 155 that protrude inward are provided in the peripheral wall 15 portion between the recesses 17. In the case of the lid 1700 in the modified example 3, where the outer casing 7 is not provided, the lid 1700 can be made lighter, and manufacturing costs can be further reduced.

[0054] Now, although various embodiments and modifications have been described above, these embodiments and modifications can of course be combined to form a complete system. Furthermore, this disclosure is not limited in any way to the embodiments described above, and can be implemented in various forms without departing from the gist of this disclosure.
