The female thread portion 20a is a female thread that extends along the inner circumferential surface of the outer cylinder portion 20. The female thread portion 20a is fitted into a male thread portion 15a provided on the outer circumferential surface of the mouth cylinder portion 15. As a result, the outer cylinder portion 20 is fixed to the mouth cylinder portion 15. That is, the second main body portion 17 is fixed to the first main body portion 13.
[0034] The inner cylinder portion 21 is cylindrical in shape and protrudes downward from the outer edge of the through hole 26c in the top wall portion 26a.

This connects the inside of the first cylindrical portion 14 and the inside of the inner cylinder portion 21 via the mouth cylinder portion 15. The outer circumferential surface of the inner cylinder portion 21 is fitted into the inner circumferential surface of the mouth cylinder portion 15. This allows the inner cylinder portion 21 to liquid-tightly seal the mouth cylinder portion 15.
[0035] The pair of ribs 19 are plate-shaped and connect the inner surface of the second cylindrical portion 18 to the outer cylindrical portion 20. The plate surface of each rib 19 faces the third direction D3. Each rib 19 can increase the strength of the second main body portion 17.
[0036] The fourth cylindrical portion 35 is cylindrical and protrudes upward from the outer edge of the through hole 26c in the top wall portion 26a. In this embodiment, the fourth cylindrical portion 35 is substantially cylindrical and extends in the first direction D1. The fourth cylindrical portion 35 may also have other shapes, such as a substantially square cylinder extending in the first direction D1. The interior of the fourth cylindrical portion 35 is connected to the interior of the first cylindrical portion 14 via the through hole 26c, the inner cylindrical portion 21, and the mouth cylindrical portion 15.
[0037] The nozzle 40 shown in Figure 2 discharges liquid L to the outside. The nozzle 40 protrudes from the fourth cylindrical portion 35 toward the tip side (+D2 side), that is, toward one side in the second direction D2. In this embodiment, the nozzle 40 is substantially cylindrical with respect to the central axis J. In this embodiment, the nozzle 40 is integrally molded with the second main body portion 17 and the fourth cylindrical portion 35. The nozzle 40 and the second main body portion 17 and the fourth cylindrical portion 35 may be made of different materials. As shown in Figure 3, the nozzle 40 has a hole portion 41 and a discharge port 42.
[0038] The hole 41 is a hole that penetrates the nozzle 40 in the second direction D2. Viewed from the second direction D2, the hole 41 is approximately circular in shape with the central axis J at its center. The rear end (-D2 side) of the hole 41 is connected to the inside of the fourth cylindrical part 35. The discharge port 42 is the front end (+D2 side) of the hole 41. The discharge port 42 opens to the front side, i.e., one side in the second direction D2. The liquid L contained inside the container body 12 is discharged from the discharge port 42 via the mouth section 15, the inner section 21, the fourth cylindrical part, and the nozzle 40.
[0039] In this embodiment, the inner diameter of the discharge port 42 is set with respect to controlling the amount of liquid L in a single drop. Specifically, the inner diameter of the discharge port 42 is set such that, when the discharge port 42 is facing downwards and liquid L flows into the hole 41, the surface tension of liquid L becomes greater than the discharge force due to the weight of liquid L when the air pressure inside the container 11 is atmospheric pressure, and liquid L is not discharged from the discharge port 42. Furthermore, the inner diameter of the discharge port 42 is set such that when the air pressure inside the container 11 is greater than atmospheric pressure by a predetermined pressure, the air pressure inside the container 11 becomes greater than the surface tension of liquid L, and liquid L is discharged. The inner diameter of the discharge port 42 is preferably 2.0 mm or less, taking into account the surface tension of liquid L.
[0040] The pressure-deformable portion 36 is integrally molded onto the upper surface of the fourth cylindrical portion 35. The pressure-deformable portion 36 is elastic. When pressed from above, the pressure-deformable portion 36 elastically deforms downwards. As materials for the pressure-deformable portion 36, for example, low-density polyethylene resin (LDPE), silicone rubber, urethane rubber, styrene-based elastomer, olefin-based elastomer, polyurethane-based elastomer, and polyester-based elastomer can be used. In this embodiment, from the viewpoint of moldability and ease of pressing, it is preferable that the pressure-deformable portion 36 is made of a styrene-based elastomer, olefin-based elastomer, polyurethane-based elastomer, or polyester-based elastomer.
[0041] When the user grips the container portion 11 with the discharge port 42 facing downwards, a portion of the liquid L inside the container body 12 flows into the hole portion 41 through the mouth portion 15, the inner portion 21, and the fourth cylindrical portion 35. In this state, when the user presses the pressure deformation portion 36 and elastically deforms it, the volume inside the container portion 11 decreases. As a result, when the air pressure inside the container portion 11 becomes higher than atmospheric pressure by a predetermined amount, the liquid L is discharged from the discharge port 42 as described above. In this embodiment, the amount of volume reduction inside the container portion 11 when the pressure deformation portion 36 is pressed is approximately the same as the volume of one drop of liquid L. Therefore, the user can dispense one drop of liquid L from the discharge port 42 by pressing the pressure deformation portion 36.
[0042] Furthermore, if the liquid L is an eye drop, the capacity of the container part 11 is preferably 5 mL or more and 20 mL or less. Considering that the user holds the container part 11 with one hand, fixes it above the face, and presses the pressure deformation part 36 with their finger to dispense the liquid L, the capacity of the container part 11 is preferably within the above range.
[0043] Figure 7 is a first perspective view showing the lid 50 of this embodiment. Figure 8 is a second perspective view showing the lid 50 of this embodiment. The lid 50 shown in Figure 1 is detachably attached to the container body 12. More specifically, the lid 50 is detachably attached to the second body portion 17. As will be described later, the lid 50 can be attached to the container body 12 by sliding the lid 50 along the guide surfaces 24a and 24b from the front end (+D2 side) to the rear end (-D2 side). The lid 50 can also be removed from the container body 12 by sliding the lid 50 along the guide surfaces 24a and 24b from the rear end to the front end. The lid 50 is a substantially rectangular tube shape extending in the first direction D1. As shown in Figure 3, the lid 50 has an opening on the bottom side. The lid 50 houses a third cylindrical portion 26, a fourth cylindrical portion 35, a press-deformable portion 36, and a nozzle 40. In this embodiment, the lid 50 is made of a resin material that is injection-mold and has a flexural modulus of 800 MPa or more. Polypropylene and acrylonitrile styrene are preferably used as the materials for the lid 50. As shown in Figures 7 and 8, the lid 50 has a lid body portion 51, a third wall portion 57a, a fourth wall portion 57b, and a sealing portion 58.
[0044] As shown in Figure 3, the lid body 51 is a roughly rectangular tube extending in the first direction D1. The lid body 51 is open on the bottom. The lid body 51 houses the third cylindrical part 26, the fourth cylindrical part 35, the pressing deformation part 36, and the nozzle 40. As shown in Figure 7, the lid body 51 has a first wall 51a and a second wall 51b. The first wall 51a is the portion of the lid body 51 on one side (+D3 side) in the third direction D3. The first wall 51a is plate-shaped with its plate surface facing the third direction D3. As shown in Figure 1, when viewed from the third direction D3, the shape of the tip side (+D2 side) portion of the lower end of the first wall 51a extends linearly in the second direction D2 from the tip end towards the rear end (-D2 side), and then curves so as to be convex towards the rear end. As shown in Figure 7, the first wall portion 51a has an opposing surface 52a and a second side surface 53a. That is, the lid body portion 51 has an opposing surface 52a and a second side surface 53a.
[0045] As shown in Figure 1, the opposing surface 52a is the tip-side (+D2 side) portion of the surface facing downwards of the first wall portion 51a. The opposing surface 52a is planar and extends in the second direction D2. The opposing surface 52a faces the guide surface 24a in the first direction D1. In this embodiment, at least a portion of the opposing surface 52a is in contact with the guide surface 24a in the first direction D1.
[0046] As shown in Figure 7, the second side surface 53a is the surface facing the other side (-D3 side) of the first wall portion 51a in the third direction D3. Although not shown in the figure, the second side surface 53a is positioned on one side (+D3 side) of the third direction D3 than the first side surface 27a. The second side surface 53a faces the first side surface 27a with a gap between them in the third direction D3. The second side surface 53a is provided with two second engaging portions 55a and 55b.
[0047] In this embodiment, each second engaging portion 55a, 55b protrudes inward from the second side surface 53a in the third direction D3. More specifically, each second engaging portion 55a, 55b protrudes from the second side surface 53a to the other side (-D3 side) of the third direction D3. Each second engaging portion 55a, 55b is a projection extending in a direction perpendicular to the second direction D2. The second engaging portion 55a is positioned further forward (+D2 side) than the second engaging portion 55b. Each second engaging portion 55a, 55b is positioned spaced apart from each other in the second direction D2. As shown in Figure 6, the second engaging portion 55a is located between the first engaging portion 28a and the first engaging portion 28b. The second engaging portion 55b is positioned further back (-D2 side) than the first engaging portion 28b.
[0048] As shown in Figure 8, the second wall portion 51b is the portion of the lid body portion 51 on the other side (-D3 side) of the third direction D3. The second wall portion 51b is plate-shaped with its surface facing the third direction D3. Similar to the first wall portion 51a described above, when viewed from the third direction D3, the shape of the lower end portion of the second wall portion 51b on the leading edge side (+D2 side) extends linearly in the second direction D2 from the leading edge towards the rear end side (-D2 side), and then curves so as to be convex towards the rear end side. The second wall portion 51b has an opposing surface 52b and a second side surface 53b. That is, the lid body portion 51 has an opposing surface 52b and a second side surface 53b.
[0049] The opposing surface 52b is the tip-side (+D2 side) portion of the surface facing downwards of the second wall portion 51b. The opposing surface 52b is planar and extends in the second direction D2. Although not shown in the illustration, the opposing surface 52b faces the guide surface 24b in the first direction D1. In this embodiment, at least a portion of the opposing surface 52b is in contact with the guide surface 24b in the first direction D1. Although not shown in the illustration, when viewed from the third direction D3, the guide surfaces 24a and 24b overlap each other.
[0050] The second side surface 53b is the surface facing one side (+D3 side) of the second wall portion 51b in the third direction D3. Although not shown in the illustration, the second side surface 53b is positioned on the other side (-D3 side) of the third direction D3 than the first side surface 27b. The second side surface 53b faces the first side surface 27b with a gap in the third direction D3. Two second engaging portions 55c and 55d are provided on the second side surface 53b.
[0051] In this embodiment, each second engaging portion 55c, 55d protrudes inward from the second side surface 53b in the third direction D3. More specifically, each second engaging portion 55c, 55d protrudes from the second side surface 53b to one side (+D3 side) of the third direction D3. Each second engaging portion 55c, 55d is a projection extending in a direction perpendicular to the second direction D2. The second engaging portion 55c is positioned further forward (+D2 side) than the second engaging portion 55d. Each second engaging portion 55c, 55d is spaced apart from each other in the second direction D2. Although not shown in the illustration, the second engaging portion 55c is located between the first engaging portion 28c and the first engaging portion 28d. The second engaging portion 55d is positioned further rearward (-D2 side) than the first engaging portion 28d.
[0052] As shown in Figure 6, the second engaging portion 55a has a second engaging surface 56a facing the tip side (+D2 side). The second engaging portion 55b has a second engaging surface 56b facing the tip side. As shown in Figure 8, the second engaging portion 55c has a second engaging surface 56c facing the tip side. The second engaging portion 55d has a second engaging surface 56d facing the tip side. Therefore, in this embodiment, each of the second engaging portions 55a to 55d has a second engaging surface 56a to 56d facing the tip side, i.e., one side of the second direction D2.
[0053] As shown in Figure 6, the second engagement surface 56a faces the first engagement surface 29a in the second direction D2. The second engagement surface 56b faces the first engagement surface 29b in the second direction D2. Although not shown in the figure, the second engagement surface 56c faces the first engagement surface 29c in the second direction D2. Although not shown in the figure, the second engagement surface 56d faces the first engagement surface 29d in the second direction D2. As a result, each of the second engagement surfaces 56a to 56d faces a different first engagement surface 29a to 29d in the second direction D2. This causes the second engagement portions 55a to 55d and the first engagement portions 28a to 28d to engage with each other. When the lid 50 attempts to move toward the tip side (+D2 side) relative to the container portion 11, the second engagement surfaces 56a to 56d come into contact with the first engagement surfaces 29a to 29d in the second direction D2. This prevents the lid 50 from easily detaching from the container body 12 toward the tip side.
[0054] In this embodiment, when a user removes the lid 50 from the container body 12 to dispense the liquid L, they apply a force toward the tip side (+D2 side) of the lid 50, bringing the second engaging portions 55a to 55d into contact with the first engaging portions 28a to 28d. As a result, the first wall portion 51a and the second wall portion 51b each elastically deform outward in the third direction D3. This allows each of the second engaging portions 55a to 55d to overcome the first engaging portions 28a to 28d, thereby moving the lid 50 toward the tip side. In other words, the first engaging portions 28a to 28d and the second engaging portions 55a to 55b are engaged with each other with a force sufficient to prevent the lid 50 from coming off the container body 12, for example, when the user is carrying the container 10. Therefore, the lid 50 can be easily removed from the container body 12 by applying a force toward the tip side of the lid 50.
[0055] The first engaging portions 28a to 28d may be holes recessed inward from the first side surfaces 27a and 27b in the third direction D3. In this case, each second engaging portion 55a to 55d is located inside a different first engaging portion 28a to 28d. Therefore, the second engaging surfaces 56a to 56d face the rear end side (-D2 side) of the inner surfaces of the different first engaging portions 28a to 28d, i.e., the first engaging surfaces 29a to 29d facing the other side of the second direction D2, in the second direction D2. This prevents the lid 50 from easily detaching from the container body 12 towards the front end side (+D2 side), similar to this embodiment.
[0056] Furthermore, the second engaging portions 55a to 55d may be holes recessed outward in the third direction D3 from the second side surfaces 53a and 53b. In this case, each first engaging portion 28a to 28d is positioned inside a different second engaging portion 55a to 55d. Therefore, the second engaging surfaces 56a to 56d of the inner surfaces of the second engaging portions 55a to 55d that face the tip side (+D2 side) face the first engaging surfaces 29a to 29d of the different first engaging portions 28a to 28d in the second direction D2. This prevents the lid 50 from easily detaching from the container body 12 towards the tip side, similar to this embodiment.
[0057] As shown in Figure 6, in the first direction D1, the second engaging portions 55a and 55b are positioned between the guide surface 24a and the restricting portion 31a. Although not shown in the figure, in the first direction D1, the second engaging portions 55c and 55d are positioned between the guide surface 24b and the restricting portion 31b. As a result, in the first direction D1, the second engaging portions 55a to 55d are positioned between the guide surfaces 24a and 24b and the restricting portions 31a and 31b. When the lid 50 attempts to move upward relative to the container portion 11, the second engaging portions 55a to 55d come into contact with the restricting portions 31a and 31b in the first direction D1. Therefore, the lid 50 is prevented from coming off the container body 12 upward. Also, as described above, the dimensions of the restricting portions 31a and 31b in the third direction D3 are larger than the dimensions of the first engaging portions 28a to 28d in the third direction D3. Therefore, the lid 50 can be more effectively prevented from detaching upward from the container body 12.
[0058] As shown in Figure 7, the third wall portion 57a is plate-shaped and extends in the first direction D1 and the third direction D3. The third wall portion 57a connects to the first wall portion 51a and the second wall portion 51b. The fourth wall portion 57b is plate-shaped with its surface facing the third direction D3. The fourth wall portion 57b is positioned further forward (+D2 side) than the third wall portion 57a. The fourth wall portion 57b connects to the third wall portion 57a and the lid body portion 51. The third wall portion 57a and the fourth wall portion 57b each contribute to increasing the strength of the lid 50 in the direction perpendicular to the first direction D1.
[0059] As shown in Figure 3, the sealing portion 58 in this embodiment is columnar in shape, protruding from the third wall portion 57a toward the rear end side (-D2 side), that is, toward the other side in the second direction D2. In this embodiment, the sealing portion 58 is substantially cylindrical in shape, protruding in the second direction D2 with respect to the central axis J. When the lid 50 is attached to the container body 12, the sealing portion 58 is inserted into the inside of the nozzle 40 through the discharge port 42. At this time, the outer circumferential surface of the sealing portion 58 is in close contact with the inner circumferential surface of the hole portion 41. As a result, the sealing portion 58 liquid-tightly seals the discharge port 42, thereby suppressing leakage of liquid L from the discharge port 42.
[0060] Figure 9 is a side view showing the procedure for attaching the lid 50 to the container body 12 of this embodiment. Next, the procedure for attaching the lid 50 to the container body 12 will be described. As shown in Figure 9, first, the user moves the lid 50, which is positioned above the container portion 11, downward so that the rear ends (-D2 side) of the opposing surfaces 52a and 52b come into contact with the front ends (+D2 side) of the guide surfaces 24a and 24b. At this time, the fourth cylindrical portion 35 and the nozzle 40 are housed inside the lid body portion 51. Next, the user slides the lid 50 toward the rear end so that the opposing surfaces 52a and 52b move along the guide surfaces 24a and 24b. In other words, the user slides the lid 50 toward the rear end along the guide surfaces 24a and 24b. At this time, when each of the second engaging portions 55a to 55d comes into contact with the first engaging portions 28a to 28d, the first wall portion 51a and the second wall portion 51b each elastically deform outward in the third direction D3. As a result, each of the second engaging portions 55a to 55d overcomes the first engaging portions 28a to 28d, allowing the lid 50 to be moved towards the rear end. When the user slides the lid 50 towards the rear end until the entire surface of the lower side of the lid body portion 51 comes into contact with the entire surface of the upper side of the stepped portion 23, the lid 50 is attached to the container body 12, as shown in Figure 1.
[0061] At this time, as shown in Figure 6, the sealing portion 58 is inserted into the hole portion 41. As a result, as described above, the sealing portion 58 seals the discharge port 42 liquid-tight, thereby preventing liquid L from leaking out of the discharge port 42. The second engaging portions 55a to 55d are engaged with the first engaging portions 28a to 28d. As a result, as described above, it is possible to prevent the lid 50 from easily coming off the container body 12 towards the tip side (+D2 side). In the first direction D1, the second engaging portions 55a to 55d are positioned between the guide surfaces 24a, 24b and the restricting portions 31a, 31b. As a result, as described above, it is possible to prevent the lid 50 from coming off the container body 12 upwards.
[0062] Although not shown in the diagram, when removing the lid 50 from the container body 12, as described above, the user applies force to the lid 50 toward the tip side (+D2 side). As described above, when the second engaging parts 55a to 55d come into contact with the first engaging parts 28a to 28d, the first wall part 51a and the second wall part 51b each elastically deform outward in the third direction D3. As a result, each of the second engaging parts 55a to 55d overcomes the first engaging parts 28a to 28d, allowing the user to easily slide the lid 50 toward the tip side. After that, the user can remove the lid 50 from the container body 12 by moving the lid 50 upward relative to the container part 11.
[0063] According to this embodiment, the container 10 comprises a container body 12 that contains liquid L and extends in a first direction D1, and a container portion 11 having a nozzle 40 that protrudes to one side (+D2 side) of a second direction D2 which is inclined with respect to the first direction D1 and discharges liquid L, and a lid 50 that is detachably attached to the container body 12. The nozzle 40 has a discharge port 42 that opens towards the tip, the container body 12 has guide surfaces 24a, 24b that extend in a direction inclined with respect to the first direction D1, the lid 50 has a lid body portion 51 that houses the nozzle 40, and a sealing portion 58 that protrudes to the rear end side (-D2 side), i.e., the other side of the second direction D2, and seals the discharge port 42, and the lid body portion 51 has opposing surfaces 52a, 52b that face the guide surfaces 24a, 24b. Therefore, as described above, the discharge port 42 can be sealed by the sealing part 58 simply by sliding the lid 50 toward the rear end relative to the container part 11 while aligning the opposing surfaces 52a and 52b of the lid 50 with the guide surfaces 24a and 24b of the container body 12. Thus, since leakage of liquid L from the discharge port 42 can be suppressed by this operation alone, the operation of sealing the discharge port 42 can be simplified.
[0064] According to this embodiment, the guide surfaces 24a, 24b and the opposing surfaces 52a, 52b are each planar and extend in the second direction D2. Therefore, by sliding the lid 50 toward the rear end side (-D2 side) relative to the container portion 11 while aligning the opposing surfaces 52a, 52b of the lid 50 with the guide surfaces 24a, 24b of the container body 12, the sealing portion 58 can be brought into contact with the nozzle 40 protruding toward the front end side (+D2 side) from the front end side. This allows the sealing portion 58 to be brought into contact with the nozzle 40 more effectively than when the lid 50 is moved toward the container portion 11 in a direction different from the second direction D2. Therefore, the discharge port 42 can be sealed more effectively by the sealing portion 58, and leakage of liquid L from the discharge port 42 can be more effectively suppressed.
[0065] According to this embodiment, the sealing portion 58 is columnar in shape and protrudes from the rear end side (-D2 side), that is, to the other side in the second direction D2. It is inserted into the nozzle 40 via the discharge port 42, and the outer circumferential surface of the sealing portion 58 is in close contact with the inner circumferential surface of the nozzle 40. As described above, in this embodiment, the lid 50 is attached to the container body 12 by sliding the lid 50 towards the rear end while aligning the opposing surfaces 52a and 52b of the lid 50 with the guide surfaces 24a and 24b of the container body 12. Therefore, the sealing portion 58 protruding from the rear end can be easily inserted into the hole 41 extending in the second direction D2 via the discharge port 42 opening on the front end side (+D2 side). Thus, the work of sealing the discharge port 42 with the sealing portion 58 can be simplified.
[0066] Furthermore, in this embodiment, it is possible to prevent the sealing portion 58 from being inserted into the hole 41 of the nozzle 40 at an angle with respect to the central axis of the hole 41. As a result, the outer circumferential surface of the sealing portion 58 and the inner circumferential surface of the nozzle 40 can be brought into good contact. Consequently, the discharge port 42 can be more effectively sealed by the sealing portion 58, and leakage of liquid L from the discharge port 42 can be more effectively suppressed.
[0067] According to this embodiment, the container body 12 has first sides 27a, 27b facing a third direction D3 which intersects with the second direction D2, and the lid body 51 has first sides 27a, 27b and second sides 53a, 53b facing the third direction D3, and the first sides 27a, 27b are provided with first engaging portions 28a to 28d that protrude outward from the first sides 27a, 27b in the third direction D3, and the second side 53a and 53b are provided with second engaging portions 55a to 55d that protrude inward in the third direction D3 from the second side surfaces 53a and 53b. The first engaging portions 28a to 28b have first engaging surfaces 29a to 29d that face the rear end side (-D2 side), i.e., the other side of the second direction D2. The second engaging portions 55a to 55d have second engaging surfaces 56a to 56d that face the first engaging surfaces 29a to 29d and the second direction D2. Therefore, as described above, the second engaging portions 55a to 55d and the first engaging portions 28a to 28d are engaged with each other. Consequently, as described above, when the lid 50 attempts to move toward the front end side (+D2 side) relative to the container portion 11, the second engaging surfaces 56a to 56d come into contact with the first engaging surfaces 29a to 29d and the second direction D2. This prevents the lid 50 from easily detaching from the container body 12 towards the tip, allowing the sealing portion 58 to more effectively seal the outlet 42. Therefore, when the user carries the container 10 around, leakage of liquid L from the outlet 42 can be more effectively prevented.
[0068] In this embodiment, the first sides 27a and 27b are provided with restricting portions 31a and 31b that protrude outward in the third direction D3 from the first sides 27a and 27b, and the second sides 53a and 53b are provided with second engaging portions 55a and 55d that protrude inward in the third direction D3 from the second sides 53a and 53b. In the first direction D1, the second engaging portions 55a and 55b are positioned between the guide surfaces 24a and 24b and the restricting portions 31a and 31b. Therefore, as described above, when the lid 50 attempts to move upward relative to the container portion 11, the second engaging portions 55a to 55d come into contact with the restricting portions 31a and 31b and the first direction D1. This prevents the lid 50 from coming off upward from the container body 12, allowing the sealing portion 58 to more effectively seal the discharge port 42. Therefore, when the user carries the container 10 around, leakage of liquid L from the outlet 42 can be more effectively suppressed.
[0069] According to this embodiment, the container portion 11 is made of an injection-molded resin material, and the lid 50 is made of an injection-molded resin material having a flexural modulus of 800 MPa or more. Therefore, the strength of the sealing portion 58 can be suitably increased, and deformation of the sealing portion 58 can be suppressed even after repeated attachment and detachment of the lid 50 to the container portion 11. As a result, the discharge port 42 can be more suitably sealed by the sealing portion 58 even after repeated attachment and detachment of the lid 50 to the container body 12. Therefore, leakage of liquid L from the discharge port 42 can be more suitably suppressed.
[0070] Furthermore, in this embodiment, the strength of the lid body portion 51 can be suitably increased. As a result, deformation of the first wall portion 51a and the second wall portion 51b can be suppressed when the user carries the container 10, and the second engaging portions 55a to 55d can be suitably engaged with the first engaging portions 28a to 28d. This makes it more suitable to suppress the lid body 50 from coming off the container body 12 when the user carries the container 10, and the sealing portion 58 can more suitably seal the discharge port 42.
[0071] <Second Embodiment> Figure 10 is an enlarged cross-sectional view showing a part of the container 210 of this embodiment. In this embodiment, the sealing portion 258 is cylindrical and protrudes from the rear end side (-D2 side), that is, to the other side in the second direction D2. In the following description, components that are the same as those in the first embodiment described above are denoted by the same reference numerals, and their descriptions are omitted.
[0072] As shown in Figure 10, the lid 250 of the container 210 in this embodiment has a sealing portion 258. The sealing portion 258 in this embodiment is cylindrical and protrudes from the third wall portion 57a toward the rear end (-D2 side), that is, toward the other side in the second direction D2. In this embodiment, the sealing portion 258 is substantially cylindrical and protrudes in the second direction D2 with respect to the central axis J. The sealing portion 258 opens toward the rear end. When the lid 250 is attached to the container body 12, the nozzle 40 is inserted into the inside of the sealing portion 258. At this time, the inner circumferential surface of the sealing portion 258 is in close contact with the outer circumferential surface of the nozzle 40. As a result, the sealing portion 258 liquid-tightly seals the discharge port 42, thereby suppressing leakage of liquid L from the discharge port 42. Other configurations of the lid 250 in this embodiment are the same as other configurations of the lid 50 in the first embodiment described above. The other configurations of the container 210 in this embodiment are the same as those of the container 10 in the first embodiment described above.
[0073] According to this embodiment, the sealing portion 258 is cylindrical in shape, protruding from the rear end side (-D2 side), that is, the other side in the second direction D2, and opening to the rear end side. The nozzle 40 is inserted into the sealing portion 258, and the inner circumferential surface of the sealing portion 258 is in close contact with the outer circumferential surface of the nozzle 40. Similar to the first embodiment described above, in this embodiment, the lid 250 is attached to the container body 12 by sliding the lid 250 towards the rear end while aligning the opposing surfaces 52a and 52b of the lid 250 with the guide surfaces 24a and 24b of the container body 12. Therefore, the nozzle protruding from the front end side (+D2 side) can be easily inserted into the sealing portion 258 that opens to the rear end side. Thus, the work of sealing the discharge port 42 with the sealing portion 258 can be simplified.
[0074] Furthermore, in this embodiment, it is possible to prevent the nozzle 40 from being inserted into the sealing portion 258 at an angle with respect to the central axis of the sealing portion 258. As a result, the inner circumferential surface of the sealing portion 258 and the outer circumferential surface of the nozzle 40 can be brought into good contact. Consequently, the discharge port 42 can be more effectively sealed by the sealing portion 258, and leakage of liquid L from the discharge port 42 can be more effectively suppressed.
[0075] <Third Embodiment> Figure 11 is an enlarged cross-sectional view showing a part of the container 310 of this embodiment. In this embodiment, the sealing portion 358 is spherical and protrudes from the rear end side (-D2 side), that is, to the other side in the second direction D2. In the following description, components that are the same as those in the first embodiment described above are denoted by the same reference numerals, and their descriptions are omitted.
[0076] As shown in Figure 11, the lid 350 of the container 310 in this embodiment has a sealing portion 358. The sealing portion 358 in this embodiment is spherical and protrudes from the third wall portion 57a toward the rear end side (-D2 side), that is, toward the other side in the second direction D2. In this embodiment, the central axis J passes through the center of the sealing portion 358. The sealing portion 358 may also have other shapes, such as a cylindrical shape protruding toward the rear end side. When the lid 350 is attached to the container body 12, the sealing portion 358 is in close contact with the tip side (+D2 side) of the nozzle 40, that is, the surface facing one side in the second direction D2. As a result, the sealing portion 358 closes the discharge port 42 of the nozzle 40. Therefore, since the sealing portion 358 liquid-tightly seals the discharge port 42, leakage of liquid L from the discharge port 42 can be suppressed. The other configurations of the lid 350 in this embodiment are the same as the other configurations of the lid 50 in the first embodiment described above. The other configurations of the container 310 in this embodiment are the same as the other configurations of the container 10 in the first embodiment described above.
[0077] According to this embodiment, the sealing portion 358 is spherical and protrudes from the rear end side (-D2 side), i.e., the other side of the second direction D2, and seals the discharge port 42 from the front end side (+D2 side), i.e., one side of the second direction D2. Similar to the first embodiment described above, in this embodiment, the lid 350 is attached to the container body 12 by sliding the lid 350 towards the rear end while aligning the opposing surfaces 52a and 52b of the lid 350 with the guide surfaces 24a and 24b of the container body 12. As a result, the sealing portion 358 protruding from the rear end can be suitably brought into close contact with the discharge port 42 opening towards the front end. This allows the discharge port 42 to be sealed liquid-tightly by the sealing portion 358. Therefore, the work of sealing the discharge port 42 with the sealing portion 358 can be simplified.
[0078] Furthermore, in this embodiment, it is possible to suppress the sealing portion 358 from tilting with respect to the central axis of the hole 41 of the nozzle 40 and making close contact with the discharge port 42. Therefore, the sealing portion 358 and the discharge port 42 can be made to be in a suitable close contact.
