[0003] Japanese Unexamined Patent Publication No. 2024-28345

[0004] After the engagement is released, the lid is pressed by the biasing portion and stands up. Depending on the biasing force of the biasing portion, the lid sometimes rotates beyond a stop angle, and stops after swinging within a range including the stop angle. In some cases, the lid could not be stopped quickly at a desired stop position.

[0005] The present invention has been made in view of the above-mentioned problem, and an object of the present invention is to provide a sheet-shaped content container capable of quickly stopping a lid at a stop position while suppressing swinging of the lid.

[0006] A sheet-shaped content container according to one aspect includes: a container body that accommodates therein a laminate in which a plurality of sheet-shaped contents are laminated, and has a take-out port for the sheet-shaped contents; and a lid that is rotatably attached to the container body about a rotation shaft, and moves between a closed state of closing the take-out port and an open direction of opening the take-out port. The sheet-shaped content container includes a biasing portion that biases the lid. In the closed state, the biasing portion biases the lid to move in the open direction. In a state where the lid is opened at a predetermined angle or more, the lid is biased by the biasing portion to suppress movement of the lid in the open direction.

Figure 2 is a perspective view of the open state of the sheet-like contents container according to the embodiment. Figure 3 is an enlarged view of the engagement portion between the container body and the lid. Figure 4 is a cross-sectional view illustrating the open and closed states of the lid. Figure 5 is an enlarged view of the receiving portion and biasing portion of the container according to a modified example.

[0008] (1) Outline of Embodiments The following matters will become clear from the description in this specification and the accompanying drawings. The invention according to Embodiment 1 is a sheet-like contents container comprising: a container body having an outlet for dispensing the sheet-like contents and containing a laminate in which a plurality of sheet-like contents are stacked inside; and a lid that is rotatably attached to the container body about a pivot axis and moves in a closed state that closes the outlet and in an open direction that opens the outlet. The sheet-like contents container comprises a biasing part that biases the lid. In the closed state, the biasing part biases the lid to move in the open direction. When the lid is opened to a predetermined angle or more, the lid is biased by the biasing part to prevent it from moving in the open direction. According to this embodiment, since the biasing part biases the lid from the closed state to the open state, it is possible to assist the movement of the lid in the open direction. Furthermore, when the lid is opened beyond a predetermined angle, it is biased by the biasing part to prevent it from moving in the opening direction, thus suppressing the lid's swinging motion and making it easier to quickly stop the lid at the desired stopping position.

[0009] In a preferred embodiment, the invention according to Embodiment 2 may have the following features in the invention according to Embodiment 1. The lid has a receiving portion that is biased by the biasing portion to prevent the lid from moving in the opening direction. One of the receiving portion and the biasing portion has a protruding portion that projects toward the other of the lid and the container body and contacts the other when opened to a predetermined angle or more. According to this embodiment, since the protruding portion is biased, the entire member does not come into contact with the other, compared to a configuration in which the entire receiving portion is biased, and damage to the member can be suppressed. Furthermore, the degree of biasing can be changed by adjusting the shape and dimensions of the protrusion.

[0010] In a preferred embodiment, the invention according to embodiment 3 may have the following features in the invention according to embodiment 2: The protruding portion is tapered toward the other side. According to this embodiment, the biasing force at the beginning of the biasing process can be made small and gradually increased, and the swinging of the lid can be suppressed by applying force in stages.

[0011] In a preferred embodiment, the invention according to embodiment 4 may have the following features in the invention according to embodiment 2 or embodiment 3. The protrusions are provided in a plurality at intervals in the axial direction of the rotating shaft. According to this embodiment, by providing a plurality of protrusions spaced apart in the axial direction of the rotating shaft, biasing can be applied over a certain range extending in the axial direction, making it easier to apply force stably to the entire lid and suppressing the oscillation of the lid.

[0012] In a preferred embodiment, the invention according to embodiment 5 may have the following features in the invention according to any of embodiments 1 to 4. The lid has a receiving portion that is biased by the biasing portion to prevent the lid from moving in the opening direction. The rotating shaft is provided on one of the lid and the container body. The other of the lid and the container body is provided with a bearing portion that rotatably holds the rotating shaft. The contact points between the rotating shaft and the bearing portion are provided in pairs at intervals in the axial direction of the rotating shaft. The biasing portion and the receiving portion are arranged between the pair of contact points in the axial direction. According to this embodiment, the receiving portion can be biased by the biasing portion over a certain range extending in the axial direction of the rotating shaft, making it easier to apply force stably to the entire lid and suppressing the swaying of the lid.

[0013] In a preferred embodiment, the invention according to embodiment 6 may have the following features in the invention according to any of embodiments 1 to 5: The biasing portion is formed of an elastic material. According to this embodiment, since the biasing is performed by the elastic force of the elastic material, the force can be applied gradually. In addition, the impact when contacting the lid can be mitigated.

[0014] In a preferred embodiment, the invention according to embodiment 7 may have the following features in the invention according to any of embodiments 1 to 6. The biasing portion is folded with a first fold and a second fold along the axial direction as base points. The region of the biasing portion folded by the first fold biases the lid in the opening direction. The region of the biasing portion folded by the second fold biases the lid in the opening direction and also biases the lid to prevent it from moving in the opening direction when it is open beyond a predetermined angle. According to this embodiment, biasing to the open state and biasing to prevent movement can be achieved with a single biasing portion.

[0015] In a preferred embodiment, the invention according to embodiment 8 may have the following features in the invention according to any of embodiments 1 to 7: The predetermined angle is an angle greater than 60 degrees. If the lid is biased to suppress movement in the opening direction at an angle less than 60 degrees, the speed and momentum of the lid's movement in the opening direction will decrease, and the lid may not open to the desired angle. By biasing the lid to suppress movement in the opening direction at an angle greater than 60 degrees, it becomes easier to open the lid to the intended angle.

[0016] In a preferred embodiment, the invention according to embodiment 9 may have the following features in the invention according to any of embodiments 1 to 8. The angle at which the biasing portion begins to contact the lid may be a predetermined angle of 80 degrees or more and 90 degrees or less. By biasing the lid toward the closed state at an angle of 80 degrees or more and 90 degrees or less against the force with which the lid opens, it becomes easier to stop the lid near 90 degrees, and oscillation can be suppressed.

[0017] (2) Sheet-like Contents Container According to the Embodiment Hereinafter, the sheet-like contents container according to the embodiment (hereinafter referred to as container 1) will be described with reference to the drawings. In the following drawings, the same or similar parts are denoted by the same or similar reference numerals. However, it should be noted that the drawings are schematic and the ratios of each dimension etc. may differ from those of reality. Therefore, specific dimensions etc. should be determined by referring to the following explanation. In addition, there may be parts where the relationships and ratios of dimensions differ between drawings.

[0018] Figure 2 is a perspective view of the container 1 according to the embodiment. The perspective views of Figures 1 and 2 are viewed from the upper right side. Figure 1 shows the closed state with the lid 20 closed, and Figure 2 shows the open state with the lid 20 open. Figure 3 is an enlarged perspective view of the engagement portion between the open lid 20 and the container body 10, as viewed from the front. Figure 4 is an enlarged cross-sectional view of the engagement portion between the lid and the container body in a cross section passing through the center of the horizontal direction Y and along the vertical direction X and the vertical direction Z. Figure 4(A) shows the closed state, and Figures 4(B) and (C) show the open state. Figure 4(B) shows the state where the predetermined angle (α) is 60 degrees, and Figure 4(C) shows the state where the predetermined angle is 90 degrees.

[0019] The container 1 has an upper surface 1A, a lower surface 1B that is opposite to the upper surface 1A in the vertical direction Z, a left side surface 1C, a right side surface 1D that is opposite to the left side surface 1C in the horizontal direction Y, a front surface 1E, and a back surface 1F that is opposite to the front surface 1E in the vertical direction X. The container 1 has a vertical direction Z, which is the height direction, and horizontal directions Y and vertical directions X that extend in the planar direction and are mutually perpendicular. The vertical direction Z is the direction that extends vertically when the outlet 11 for removing sheet-like contents is positioned facing upwards. The upper side is the upper surface 1A side (outlet 11) side, and the lower side is the lower surface 1B side. The vertical direction X and horizontal direction Y are directions perpendicular to the vertical direction Z, and extend horizontally when the outlet 11 is positioned facing upwards. The vertical direction X is the depth direction in a front view. The horizontal direction Y is the left-right direction in a front view and may be the longitudinal direction of the stacked body. The vertical direction Z may be aligned with the thickness direction of the sheet-like contents.

[0020] The container 1 comprises a container body 10 that houses a laminate and has an outlet 11 for dispensing sheet-like contents, and a lid 20 that is rotatably attached to the container body 10 about a pivot axis 31 and moves in a closed state that closes the outlet 11 and in an open direction that opens the outlet 11. The laminate consists of multiple sheets of sheet-like contents stacked on top of each other. The sheet-like contents can be made of sheets such as nonwoven fabric, woven fabric, and paper, and examples include dry sheets, wet sheets (wet wipes and face masks), and masks. The wet or dry sheets may be sheets for use on the hands, face, or other parts of the body, or sheets for cleaning. In this embodiment, the sheet-like contents are wet wipes.

[0021] The laminate may be housed in the container body 10 in its laminated state, or it may be housed in the container body 10 while enclosed in a packaging body. The packaging body may be made of, for example, a plastic film. The packaging body may have a packaging opening. The packaging opening serves as an outlet for the sheet-like contents. The packaging opening may overlap the outlet 11 of the container body 10 and be covered by a lid 20.

[0022] The container body 10 may have an upper part 10A, a lower part 10B, and a wall portion 12 extending vertically Z between the upper part 10A and the lower part 10B. The upper part 10A constitutes the upper surface of the container, the lower part 10B constitutes the lower surface 1B of the container 1, and the wall portion 12 constitutes the left side 1C, right side 1D, front 1E, and back 1F of the container 1. The container body 10 has a storage space for accommodating the stacked material. The storage space is the space enclosed by the upper part 10A, the lower part 10B, and the wall portion 12.

[0023] The upper part 10A is provided with a locking mechanism 15 that locks the lid 20 in the closed position, and an operating part 16 that releases the locking state of the locking mechanism 15. The locking mechanism 15 is a claw that engages with the engaging part 23 of the lid 20 in the closed position, locking the lid 20 in the closed position. The operating part 16 is located on the upper surface 1A of the housing 1 and works in conjunction with the locking mechanism 15. When the user presses the operating part 16, the locking state of the locking mechanism 15 and the engaging part 23 is released.

[0024] An outlet 11 is provided in the upper part 10A. The outlet 11 is an opening formed in the upper part 10A and communicates with the storage space. The upper part 10A has a recess formed therein in which the biasing part 35 and the lid 20, which will be described later, are housed. The recess is recessed towards the lower part 10B. The recess has a first recess 17 that houses the plate-shaped upright part 21 of the lid 20, and a second recess 18 located on one end X1 in the vertical direction X of the container body 10 and housing the biasing part 35 and the sliding contact part 22 of the lid 20. Here, one end X1 in the vertical direction X is the side of the rotation axis 31 and is the base point side for the rotational movement of the lid 20. The other end X2 in the vertical direction X is the side of the operating part 16 and is the leading end side for the rotational movement of the lid 20.

[0025] An outlet 11 is formed in the first recess 17. A main body rib 14 is formed on the upper side along the outer edge of the first recess 17. The main body rib 14 abuts against the lid rib 24 of the lid 20 when it is closed. The second recess 18 is located at one end X1 in the vertical direction X from the first recess 17. Upper wall portions 13 are provided on both sides of the second recess 18 in the lateral direction Y, projecting upward from the second recess 18. The upper wall portions 13 are provided in pairs, spaced apart in the lateral direction Y. A rotating shaft 31 is connected to each upper wall portion 13. The rotating shaft 31 extends inward from the upper wall portion 13 in the lateral direction Y and is rotatably held by the bearing portion 32 of the lid 20.

[0026] The rotating shaft 31 may be provided on one of the lid 20 and the container body 10, and the bearing portion 32 may be provided on the other of the lid 20 and the container body 10. In this embodiment, the rotating shaft 31 is provided on the container body 10, and the bearing portion 32 is provided on the lid 20. The rotating shaft 31 may be integrated with one of the container body 10 and the lid 20, or it may be a separate part connected to one of the container body 10 and the lid 20. In this embodiment, the rotating shaft 31 is formed integrally with the container body 10 and is aligned with the lateral direction Y at one end X1 in the vertical direction of the containment body 1. The bearing portion 32 is formed integrally with the lid 20.

[0027] The lid 20 is positioned on the upper surface 1A of the container 1 and is configured to open and close the outlet 11 of the container body 10. The lid 20 is rotatably attached to the container body 10 about a pivot axis 31. In this embodiment, the lid 20 opens and closes with one end X1 in the vertical direction X as the pivot point. The lid 20 moves between a closed state, as shown in Figure 1, which closes the outlet 11, and an open state, as shown in Figure 2, which opens the outlet 11. In the closed state, the engaging portion 23 at the other end of the lid 20 in the vertical direction X engages with the locking mechanism 15 of the container body. When the user presses the operating portion 16 of the container body 10, the engagement between the locking mechanism 15 and the engaging portion 23 is released, and the lid 20 becomes movable in the opening direction. Here, the closed state is the state locked by the locking mechanism 15. Furthermore, the movement of the lid 20 in the opening direction is the movement in the direction in which the opening angle (a predetermined angle) of the lid 20 increases.

[0028] As shown in Figure 4, the lid 20 may have an upright portion 21 that stands upright on the upper side around the rotation axis 31 when opened from a closed state, and a sliding contact portion 22 that moves toward the biasing portion 35 side (the other end X2 in the vertical direction X) around the rotation axis 31 and slides against the biasing portion 35. The upright portion 21 may extend in the planar direction on the upper surface 1A. On the lower surface of the upright portion 21, a lid rib 24 is erected that contacts the main body rib 14 when the lid is closed. The sliding contact portion 22 is connected to one end of the upright portion 21 in the vertical direction X and may extend downward from the upright portion 21 when the lid is closed. The length of the sliding contact portion 22 in the lateral direction Y may be shorter than the length of the upright portion 21 in the lateral direction Y. The rotation axis 31 is inserted into both ends of the sliding contact portion 22 in the lateral direction Y, and bearing portions 32 that movably hold the rotation axis 31 are provided. The bearing portion 32 is a hole into which the rotating shaft 31 is inserted, and is located at both ends of the sliding contact portion 22 in the lateral direction Y. The sliding contact portion 22 and the bearing portion 32 are sandwiched between the rotating shaft 31 and the upper wall portion 13 in the lateral direction Y.

[0029] The container 1 of this embodiment is configured to quickly stop the lid 20 at a stopping position while suppressing the swinging of the lid 20. Next, the configuration for quickly stopping the lid 20 at a stopping position while suppressing the swinging of the lid 20 will be described in detail. The container 1 includes a biasing part 35 that biases the lid 20. The biasing part 35 engages with the container body 10 and the lid 20 respectively, and biases the lid 20 in different ways depending on the angle at which the lid 20 opens. In this embodiment, the biasing part 35 is formed separately from the container body 10 and the lid 20. However, in a modified example, the biasing part 35 may be formed integrally with the container body 10 or integrally with the lid 20.

[0030] The biasing portion 35 in this embodiment is composed of a plate-shaped elastic member having a predetermined width in the lateral direction Y. As shown in Figure 3, the biasing portion 35 is positioned in a region sandwiched between a pair of bearing portions 32 in the lateral direction Y. The length of the biasing portion 35 in the lateral direction Y is shorter than the distance between the pair of bearing portions 32. As shown in Figure 4, one end 351 of the biasing portion 35 is fixed to the lid 20, and the other end 352 of the biasing portion 35 is fixed to the container body 10. More specifically, the lid 20 has a first biasing fixing portion 29 that fixes one end 351 of the biasing portion 35. One end 351 of the biasing portion 35 is sandwiched between the lower surface of the upright portion 21 and the first biasing fixing portion 29 and fixed to the lid 20. The container body 10 has a second biasing fixing portion 19 that fixes the other end 352 of the biasing portion 35. The other end 352 of the biasing portion 35 is fixed in the second recess 18 of the container body 10 by the second biasing fixing portion 19.

[0031] Multiple folds are formed along the transverse direction Y between one end 351 and the other end 352 of the biasing portion 35. The folds are arranged from top to bottom as a first fold F1, a second fold F2, and a third fold F3. The first fold F1 and the third fold F3 are located on one end X1 in the vertical direction X of the biasing portion 35, and the second fold F2 is located on the other end X2 in the vertical direction X of the biasing portion 35. The first biasing fixing portion 29 fixes the area between the first fold F1 and the one end 351 of the biasing portion 35 to the lid 20. The second biasing fixing portion 19 fixes the area between the third fold F3 and the other end 352 of the biasing portion 35 to the container body 10. The regions folded by the first fold F1, the second fold F2, and the third fold F3 overlap each other in the closed state, but in the open state, they unfold from each fold as a base point, and the folded regions separate from each other.

[0032] Figure 4(A) shows the closed state. When the lid moves from the closed state in the opening direction (the direction in which the angle of opening of the lid increases), the biasing part 35 biases the lid 20 to move in the opening direction. More specifically, the biasing part 35 deforms to unfold with the first fold F1, second fold F2, and third fold F3 as pivot points, thereby biasing the lid 20. When the lid is slightly unfolded from the closed state (for example, rotated by less than 10 degrees), the biasing part 35 deforms to unfold with the first fold F1 and third fold F3 as pivot points, and the lid 20 moves in the opening direction around the rotation axis 31. Figure 4(B) shows the lid open to a predetermined angle of about 60 degrees. The predetermined angle is the angle between the upper surface of the upright portion 21 in the closed state and the upper surface of the upright portion 21 in the open state, as viewed from the extension of the rotation axis 31 in the axial direction. In the state shown in Figure 4(B), the biasing portion 35 unfolds with the third fold F3 as the starting point, and as the second fold F2 moves upward, it unfolds with the second fold F2 as the starting point, so that one end 351 of the biasing portion 35 biases the lower surface of the upright portion via the first fold F1.

[0033] In this embodiment, the biasing portion 35 biases the lid 20 from a closed state to an open state, thereby assisting the movement of the lid 20 in the opening direction. In the housing 1 having a locking mechanism 15, the lid 20 is biased in the opening direction by the biasing portion 35, but its movement is restricted by the locking mechanism 15. Therefore, when the locking mechanism 15 is released, the lid 20 is pressed by the biasing portion 35 and rotates around the rotation axis 31, moving in the opening direction.

[0034] When the lid 20 is opened beyond a predetermined angle, the lid 20 is biased by the biasing portion 35 to prevent it from moving further open. More specifically, as shown in Figure 4(C), as the lid 20 rotates, the sliding contact portion 22 moves toward the biasing portion 35. When opened to the predetermined angle, the sliding contact portion 22 of the lid 20 contacts the vicinity of the third fold of the biasing portion 35 and is biased by the biasing portion 35. Furthermore, as the biasing portion 35 deforms to unfold with the second fold F2 as the pivot point, the sliding contact portion 22 is biased via the third fold F3. As a result, the sliding contact portion 22 is biased by the biasing portion 35, preventing the lid 20 from moving further in the opening direction. According to this embodiment, when the lid 20 is open beyond a predetermined angle, the lid 20 is biased by the biasing part 35 to prevent it from moving in the opening direction, thereby suppressing the swinging of the lid 20 and making it easier to quickly stop the lid 20 at a desired stopping position.

[0035] Furthermore, examples of biasing mechanisms to prevent the lid 20 from moving in the opening direction include a biasing mechanism 35 that strikes the lid 20 as it moves in the opening direction to reduce its speed of movement in that direction, and a biasing mechanism 35 that strikes the lid 20 as it moves in the opening direction to restrict its movement in that direction (preventing further movement). By providing the biasing mechanism 35, it is possible to suppress the lid 20 from moving forcefully in the opening direction and to suppress the lid 20 from rotating beyond the stopping angle and swinging within a range that includes the stopping angle. In addition, by providing the biasing mechanism 35, it is possible to suppress the lid from moving forcefully in the opening direction and exceeding the stopping angle, making it easier for the lid to stop at the intended stopping position.

[0036] The lid 20 may have a receiving portion that is biased by the biasing portion 35. The receiving portion is the part that the biasing portion 35 contacts. The receiving portion of this embodiment has a first receiving portion 27 that is biased toward the opening direction when closed, and a second receiving portion 28 that is biased so as to prevent the lid 20 from moving toward the opening direction when open. The second receiving portion 28 is biased by the biasing portion 35 so as to prevent the lid 20 from moving toward the opening direction, and thus constitutes the "receiving portion" of the present invention. The first receiving portion 27 is the part that one end 351 of the biasing portion 35 contacts, and is composed of a first biasing fixing portion 29 and the lower surface of the upright portion 21. The second receiving portion 28 is the part that the portion of the biasing portion 35 near the third fold F3 contacts, and is composed of the tip of the sliding contact portion 22.

[0037] As shown in Figure 3, the contact points between the rotating shaft 31 and the bearing portion 32 may be provided in pairs, spaced apart in the axial direction of the rotating shaft 31. The biasing portion 35 and the second receiving portion 28 may be positioned between the pair of contact points in the axial direction. According to this embodiment, the biasing portion 35 can bias the second receiving portion 28 over a certain range extending in the axial direction of the rotating shaft 31, making it easier to apply stable force to the entire lid 20 and suppressing the oscillation of the lid 20.

[0038] The biasing portion 35 may be made of an elastic material. According to this embodiment, since the lid is biased by the elastic force of the elastic material, force can be applied to the lid 20 gradually. In addition, the impact when contacting the lid 20 can be mitigated. Silicone rubber can be an example of the elastic material constituting the biasing portion.

[0039] The biasing section 35 has the function of biasing the lid to move in the opening direction when it is closed, and the function of biasing the lid to prevent it from moving in the opening direction when it is open to a predetermined angle or more. The biasing section that realizes these two functions may be made up of separate members, or it may be made up of a single member as in this embodiment. The biasing section 35 that has two functions made up of a single member may be folded with a first fold F1 and a second fold F2 along the axial direction of the rotation axis 31 as the starting points. The area folded by the first fold F1 of the biasing section 35 biases the lid 20 in the opening direction, and the area folded by the second fold F2 of the biasing section may bias the lid 20 in the opening direction and prevent it from moving in the opening direction when it is open to a predetermined angle or more. According to this embodiment, biasing to the open state and biasing to prevent movement can be realized with a single biasing section 35.

[0040] The predetermined angle may be an angle greater than 60 degrees. That is, when the lid 20 is open 60 degrees or more from the closed state, the lid 20 may be biased by the biasing part 35 to prevent it from moving in the opening direction. If the lid 20 is biased to prevent it from moving in the opening direction at an angle of less than 60 degrees, the speed and momentum of the lid 20's movement in the opening direction will be reduced, and the lid 20 may not open to the desired angle. By biasing the lid 20 to prevent it from moving in the opening direction at an angle greater than 60 degrees, the lid 20 becomes easier to open to the intended angle.

[0041] The biasing portion 35 may begin to contact the lid 20, which is moving in the opening direction, when it is at a predetermined angle of 80 degrees or more and 90 degrees or less. That is, when the lid is opened less than 80 degrees from the closed state, the biasing portion 35 does not contact the second receiving portion 28, and when the lid 20 is opened 80 degrees or more and 90 degrees or less from the closed state, the biasing portion 35 may contact the second receiving portion 28. According to this embodiment, by biasing the lid 20 toward the closed state at an angle of 80 degrees or more and 90 degrees or less against the force with which the lid 20 is opening, it becomes easier to stop the lid 20 near 90 degrees, and oscillation can be suppressed.

[0042] (3) Container according to modified example Next, the container according to a modified example will be described with reference to FIG. In the following description of the modified example, the same reference numerals are used for configurations similar to those of the above-described embodiment, and the description thereof is omitted. FIG. 5 is a partially enlarged view of the container 1 with the lid opened 90 degrees (the state shown in FIG. 4(C)) viewed from the lower surface side, and is an enlarged view of the sliding contact portion 22 and the biasing portion 35.

In the above-described embodiment, the second receiving portion 28 formed by the tip end of the sliding contact portion 22 extends linearly in the lateral direction Y. The surface of the biasing portion 35 that comes into contact with the second receiving portion 28 is a flat surface with no unevenness formed thereon. Therefore, the second receiving portion 28 and the biasing portion 35 are in planar contact with each other.

[0044] In the container according to the modified example, one of the second receiving portion 28 and the biasing portion 35 has a protruding portion that protrudes toward the other of the lid body 20 and the container body 10 and comes into contact with the other when the lid body is opened at a predetermined angle or more. According to this aspect, since the protruding portion is biased, compared to a configuration in which the entire second receiving portion 28 is biased, the entire members do not come into contact with each other, and damage to the members can be suppressed. Further, by adjusting the shape and dimensions of the protrusion, the degree of biasing can be changed. In the following modified examples, the protruding portion is provided on the second receiving portion 28, but in other embodiments, it may be provided on the biasing portion 35.

[0045] The protruding portion 41 in the container 1S of modified example 1 is arranged in a band shape at a position facing the center of the biasing portion 35 in the lateral direction Y. According to this aspect, since the protruding portion 41 extends over a certain range extending in the lateral direction Y, even when a positional deviation occurs between the biasing portion 35 and the protruding portion 41 in the lateral direction Y, they can easily come into contact with each other. The length of the protruding portion 41 in the lateral direction Y may be shorter than the length of the biasing portion 35 in the lateral direction Y.

[0046] In the container 1T of modification 2, the protruding portion 42 has a tapered shape toward the other side. In the configuration where the protruding portion 42 is formed on the second receiving portion 28, the protruding portion 42 has a tapered shape toward the biasing portion 35. According to this aspect, the biasing force in the initial state of biasing can be reduced and gradually increased, so that force can be applied stepwise to suppress swinging of the lid body 20.

[0047] A plurality of protruding portions 43 of the container 1U of modification 3 and 44 of the container 1V of modification 4 are provided at intervals in the axial direction of the rotating shaft 31. According to this aspect, by providing a plurality of protruding portions spaced apart in the axial direction, biasing can be performed over a certain range extending in the axial direction, it is easy to stably apply force to the entire lid body, and swinging of the lid body 20 can be suppressed.

[0048] The interval in the lateral direction Y between adjacent protruding portions is not limited. As shown in modification 3, the protruding portions 43 may be disposed to face regions located on both lateral sides among regions obtained by dividing the biasing portion 35 into three equal parts in the lateral direction Y. The elastic member constituting the biasing portion 35 is prone to deflection at end portions in the lateral direction Y. Therefore, by disposing the protruding portions 43 to face the regions located on both lateral sides of the biasing portion 35 in the lateral direction Y, the biasing force can be more easily received.

[0049] A plurality of protruding portions 44 of the container 1V according to modification 4 may be arranged side by side in the lateral direction Y in a region straddling the center of the biasing portion 35 in the lateral direction Y. According to this aspect, since the protruding portions 44 extend over a certain range extending in the lateral direction, even when positional deviation occurs between the biasing portion 35 and the protruding portions 44 in the lateral direction, they can easily come into contact with each other.

[0050] The present invention has been described in detail above using the foregoing embodiments, but it is obvious to those skilled in the art that the present invention is not limited to the embodiments described in the present specification. The present invention can be implemented as modified and altered embodiments without departing from the spirit and scope of the present invention defined by the description of the claims. Therefore, the description of the present specification is for the purpose of illustrative explanation, and does not have any restrictive meaning with respect to the present invention.
