[0001] The present invention relates to a container with a lid.
Background Art
[0002] Some containers with lids having a lid body that opens and closes the opening of the container body by a hinge are provided with a free stop mechanism for fixing the lid body at an arbitrary angle. The free stop mechanism fixes the lid body at an arbitrary position by using, for example, the frictional force between a pin that serves as the rotation axis of the hinge and a shaft hole into which the pin is inserted. Incidentally, the compact container described in Patent Document 1 below has a free stop mechanism constituted by an O-ring made of an elastic body fixed to the shaft hole of the hinge and a pin press-fitted into the O-ring.

Summary of the Invention
Problems to be Solved by the Invention
[0004] In a free stop mechanism that uses the frictional force between a pin and a shaft hole, as the lid body is opened and closed, the contact surface between the rotation axis and the shaft hole gradually wears, making it difficult to fix the lid body at an arbitrary angle. When the pin is made of metal and either the container body or the lid body in which the shaft hole is formed is made of resin, the inner peripheral surface of the shaft hole is likely to wear. Further, in order to suppress wear of the pin and the shaft hole, a free stop mechanism that uses the frictional force generated between the outer peripheral surface of a tube made of an elastic body or the like mounted around the pin and the inner peripheral surface of the shaft hole is also conceivable.
[0005] However, when a pin is inserted through a tubular or ring-shaped elastic body as described in Patent Document 1, the elastic body is constantly squeezed between the outer surface of the rotating shaft and the inner surface of the shaft hole with a strong force. As a result, the elasticity of the elastic body deteriorates over time, and the force with which the elastic body presses the rotating shaft radially inward gradually decreases, making it difficult to fix the lid at any desired angle. Thus, in free-stop mechanisms based on a structure in which a pin is inserted through an elastic body, malfunctions due to changes over time become a problem.
[0006] Increasing the thickness (difference between outer and inner diameter) of tubular or ring-shaped elastic bodies could potentially slow down deterioration over time, but this would require more space to incorporate a free-stop mechanism in the container, making it difficult to miniaturize the container or ensure sufficient storage capacity.
[0007] Therefore, the present invention aims to provide a lidded container equipped with a free-stop mechanism that can ensure capacity while suppressing malfunctions due to frequent opening and closing operations and changes over time. [Means for solving the problem]
[0008] One aspect of the present invention for achieving the above objective is a container comprising a container body having an opening for storing contents, a hinge having a pivot axis in the left-right direction, and a lid connected via the hinge to cover the opening so as to be openable and closable, The container body and the lid are designated as the first member, and the other of the container body and the lid is designated as the second member. A pin-shaped member is provided that protrudes from the first member in the same axial direction as the rotation axis in a manner that prevents rotation, A wall surface provided on the second member that abuts against the tip of the pin-shaped member, It has, At least one of the pin-shaped member and the wall surface is formed of an elastic material, The tip of the pin-shaped member contacts the wall surface, and as the lid opens and closes, a frictional force is generated between the tip and the wall surface, causing the lid to rotate around the rotation axis so that it can be fixed in the open position. It is a container with a lid.
[0009] In the container body and the lid, the left-right, front-back, and up-down directions, which are orthogonal to each other, are defined with reference to the closed state in which the lid is closed. The rotation axis of the hinge is located on the rear end side of the first member and the second member. The first member has end protrusions that project backward at both the left and right ends of its rear end, and a central protrusion that projects backward and faces the left and right inner end faces of the end protrusions via notches that open in the vertical direction. The end projection has through holes formed coaxially with the rotation axis, connecting to the notch from the left and right outer sides. The central protrusion has recesses formed on its left and right outer end faces that extend in the same axial direction as the rotation axis, with openings on each end face. The pin-shaped member is inserted into the recess, with its tip protruding from the opening of the recess. The second member has an engaging projection at its rear end that engages with the notch, The engaging projection has a bearing recess on the end face facing the end projection into which the hinge pin is inserted, and a wall surface on the end face facing the central projection into which the tip of the pin-shaped member abuts. The pin-shaped member can also be a lidded container, which is held between the wall surface and the bottom of the recess in a compressed state in the direction of the rotation axis.
[0010] Alternatively, in the container body and the lid, the left-right, front-back, and up-down directions, which are orthogonal to each other, are based on the closed state in which the lid is closed. The first member has end protrusions that project backward at both the left and right ends of its rear end, and a central protrusion that projects backward at the center of the left and right ends of its rear end. The left and right end faces of the central protrusion face each other in the left-right direction, via a notch that opens in the vertical direction, and the right end face of the left end protrusion of the left end protrusion and the left end face of the right end protrusion, respectively. The end projection has through holes formed coaxially with the rotation axis, connecting to the notch from the left and right outer sides. The second member has an engaging projection at its rear end that engages with the notch, The engaging projection has a bearing hole formed coaxially with the rotation axis, connecting a first end face facing the end projection and a second end face facing the central projection. A wall member made of an elastic material and having the wall surface is fixed to the second end face. The pin-shaped member also serves as the pin of the hinge, and the pin-shaped member is fixed to the end projection so as not to rotate, and is rotatably inserted into the bearing hole with respect to the engaging projection, with its tip protruding from the second end face. The wall member can also be a container with a lid, in which the surface facing the second end face is the wall surface, and it is held between the tip and the central protrusion of the pin-shaped member in a compressed state in the direction of the rotation axis.
[0011] The second end face may be formed in a frame shape, and the wall member may be arranged within the frame, resulting in a container with a lid.
[0012] The container can also be made of resin, with the hinge, the container body, and the lid being detachably attached to the second member, thus forming a lidded container. In the closed state, the second member is positioned above the first member. The hinge, the container body, and the lid are made of resin. The wall member has a plate-shaped wall portion with the direction of the rotation axis as the thickness direction, and a plate-shaped base portion having a surface normalized to the vertical direction at the upper end of the wall portion. A wall insertion hole is formed on the upper surface of the second member, which connects to the frame. The container can also be a lidded container in which the wall portion is inserted into the wall insertion hole so as to be removable and placed within the frame.
[0013] In the closed state, the second member is positioned above the first member. The second member may be a container with a lid, which consists of a box-shaped top plate that is open downward and a main body that is detachable from the top plate. The elastic body is attached to the main body and is concealed by the top plate.

[0016] Embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings used in the following description, the same or similar parts may be denoted by the same reference numeral, and redundant explanations may be omitted. If a part is denoted by a reference numeral in one drawing, it may not be denoted in other drawings if it is not necessary. ===maker=== The free-stop mechanism in the lidded container according to the embodiment is based on a configuration consisting of a pin-shaped member fixed non-rotatably to either the container body or the lid, while being arranged coaxially with the rotation axis of the hinge connecting the container body and the lid, and a wall surface formed on the other side that abuts against the tip surface of the pin-shaped member. In the container according to the embodiment, the lid can be fixed to the container body at any angle using the frictional force generated between the tip surface of the pin-shaped member and the wall surface. Below, we will describe the first and second embodiments, which have the above basic configuration but differ in the specific configuration of the free-stop mechanism and the configuration of the hinge, etc. ===First Example=== Figures 1A and 1B show the external appearance of a lidded container (hereinafter sometimes referred to as "container 1") according to the first embodiment. Container 1 according to the first embodiment is a so-called "compact container," and as shown in Figure 1A, it consists of a container body 2 in which the contents such as cosmetics are stored, and a lid 3 that opens and closes the opening 21 of the container body 2 by a hinge. Figure 1A shows container 1 in the open state (hereinafter sometimes referred to as the "open state"), and Figure 1B shows container 1 in the closed state (hereinafter sometimes referred to as the "closed state").
[0017] Here, the three mutually orthogonal directions are defined as the front-to-back direction, the left-to-right direction, and the up-to-down direction, and these three directions in the container body 2 and lid 3 are defined individually based on the closed state. The front-to-back direction and the left-to-right direction are defined by assuming that the openings (21, 31) of the container body 2 and lid 3 are rectangular in shape with sides in the front-to-back and left-to-right directions, and that the container body 2 and lid 3 are connected at the rear end by a hinge having a rotation axis (hereinafter sometimes referred to as "axis 100") in the left-to-right direction. Furthermore, the up-to-down direction is defined by assuming that the bottom surface of the container body 2 is facing downwards in the closed state. Therefore, the lid 3 is a flat box shape with a top surface at the top and an open bottom. The left-to-right direction follows the left-to-right relationship when viewed from the front to the rear with the container 1 in the closed state upright with the downward direction vertically downwards, as shown in Figures 1A and 1B. Note that the vertical and horizontal directions of the lid 3 in the open state differ from the vertical and horizontal directions of the container body 2. Therefore, in the following figures, including Figures 1A and 1B, the arrows indicating the vertical, horizontal, and horizontal directions of the container body 2 are shown with solid lines, while the arrows indicating the directions of the lid 3 are shown with dashed lines.
[0018] The container body 2 is a flat, box-shaped container with a bottom, made of resin (e.g., PET). The lid 3 is a flat, box-shaped container with its top surface open downwards, and is made of the same material as the container body 2. A mirror 32 is attached to the inner top surface of the lid 3. As shown in Figure 1A, a hook 33 protruding downwards is formed at the front end of the lid 3, and a locking piece 22 that engages with the hook 33 is formed on the front end surface of the container body 2. When closed, the hook 33 and the locking piece 22 engage to prevent the lid 3 from opening unintentionally.
[0019] Figure 2 shows a diagram of container 1 disassembled into its individual parts. Figure 3A shows a perspective view of the main part of container body 2, viewed from the upper right rear. As shown in Figure 3A, narrow protrusions in the left-right direction (hereinafter sometimes referred to as "end protrusions 23a") are formed at both the left and right ends of the rear of container body 2, and a wide protrusion in the left-right direction (hereinafter sometimes referred to as "central protrusion 23b") is formed in the center. The space between the left and right end protrusions 23a and the central protrusion 23b is a notch 23c that opens vertically.
[0020] Each of the left and right end protrusions 23a has a through hole (hereinafter sometimes referred to as "axis hole 24") that connects from the left and right outer end faces 24a to the notch 23c. In addition, on both the left and right end faces 26 of the central protrusion 23b, a bottomed hole-like recess (hereinafter sometimes referred to as "fitting recess 25") that opens with the left and right direction as the depth direction is formed coaxially with the axis hole 24. The pin-shaped member 4 shown in Figure 2 is fitted into the fitting recess 25 in a tight fit state. The pin-shaped member 4 constitutes part of the free-stop mechanism and is made of an elastic material such as elastomer. Figure 3B shows the state in which the pin-shaped member 4 is fitted into the fitting recess 25, in contrast to Figure 3A. As shown in the figure, the tip 41 of the pin-shaped member 4 protrudes from the left and right end faces 26 of the central protrusion 23b. Furthermore, the tip 41 of the pin-shaped member 4 is not sharp, but is a surface perpendicular to the axis 100.
[0021] As shown in Figure 2, a protrusion (hereinafter sometimes referred to as the "engaging protrusion 34") is formed at the rear end of the lid 3, which is shaped to engage with the notch 23c of the container body 2. Furthermore, bottomed recesses (35a, 35b) that are coaxial with the shaft hole 24 are formed on both the left and right end faces (36, 37) of the engaging protrusion 34. In the following, the recesses (35a, 35b) that open on the left and right outer end faces (36, 37) of the engaging protrusion 34 will be referred to as the "shaft bearing hole 35a" if the recess 35a opens on the left and right outer end face 36, and as the recess 35b that opens on the left and right inner end face 37 if the recess 35b opens on the left and right inner end face 37.
[0022] In the container 1 of the first embodiment, the pin (hereinafter sometimes referred to as "hinge pin 5") pivotally supported by the container body 2 and the lid 3 as a hinge component is a hollow cylindrical split pin with slits 51 formed on its side surface that extend in the direction of axis 100 from the base end, which is the left and right outward end, to the tip, which is the left and right inward end. Furthermore, an axial hole 24 is formed in the end projection 23a, extending from the left and right outward direction to the notch 23c, and the hinge pin 5 is inserted through this axial hole 24, with the tip protruding from the axial hole 24 being inserted into the bearing hole 35a. This constitutes the hinge in the container 1. The free-stop mechanism in the container 1 consists of a pin-shaped member (hereinafter sometimes referred to as "stop pin 4") fitted into the fitting recess 25, and a pin receiving hole 35b into which the tip 41 of the stop pin 4 is inserted.
[0023] Figure 4 shows a view of the cross-section of the container 1 in its closed state, as seen from the rear, when it is cut by a plane that includes the axis 100 and extends in both the vertical and horizontal directions. Figure 4 corresponds to the area indicated by the dotted cylinder 101 in Figure 1B. Below, the assembly procedure of the container 1 according to the first embodiment will be explained with reference to Figures 2 to 4, and the configuration and operation of the hinge and free-stop mechanism will be explained in more detail.
[0024] The assembly procedure for container 1 begins by firmly fitting the stop pin 4 into the recess 25. Next, the engaging projection 34 of the lid 3 is engaged with the notch 35c of the container body 2 so that the shaft hole 24, the bearing hole 35a, the pin receiving hole 35b, and the recess 25 are coaxial. Note that the left and right inner surfaces 37 of the engaging projection 34 of the lid 3, which face the central projection 23b of the container body 2, are chamfered so that the lower end is tapered, as shown in the dotted circle 102 in Figure 4. As the engaging projection 34 is engaged with the notch 23c, the tips 41 of the stop pin 4 protruding from both the left and right ends of the central projection 23b are guided by the tapered surfaces of the engaging projection 34, and the stop pin 4 is squeezed between the bottom surface 27 of the recess 25 and the left and right inner end surfaces 37 of the engaging projection 34 and compressed in the axial direction 100. Then, as the tip 41 of the stop pin 4 is inserted into the pin receiving hole 35b, overcoming the tapered surface of the engaging projection 34, the stop pin 4 is squeezed between the bottom surface 38 of the pin receiving hole 35b and the bottom surface 27 of the fitting recess 25, and is compressed in the axial direction 100. As a result, the engaging projection 34 of the lid 3 engages with the notch 23c of the container body 2, and the shaft hole 24, shaft receiving hole 35a, pin receiving hole 35b, and fitting recess 25 are arranged coaxially.
[0025] Once the engaging projection 34 of the lid 3 engages with the notch 23c of the container body 2, the hinge pin 5 is inserted through the openings of the left and right outer end faces 24a of the shaft hole 24, and the tip of the hinge pin 5 is inserted into the bearing hole 35a on the lid 3 side, with the tip protruding from the openings (outlets) of the left and right inner end faces 24b. Note that the diameter of the shaft hole 24 is smaller on the outlet side than on the inlet side. Also, the diameter gradually decreases from the left and right outer directions to the inward direction near the outlet.
[0026] On the other hand, the hinge pin 5 is a split pin having a slit 51 extending in the direction of the axis 100, and an annular portion 52 is formed on its side surface that protrudes radially outward from the axis 100 and revolves around the axis 100. The annular portion 52 has a shape in which a cylinder and a frustocone are successively formed in that order from the left and right outer sides to the inside, and the outer diameter of the cylindrical portion of the frustocone portion gradually decreases toward the left and right inner sides. Furthermore, the vicinity of the opening of the bearing hole 35a in the engaging projection 34 of the lid 3 gradually decreases in diameter toward the back from the opening.
[0027] Then, as the hinge pin 5 is inserted into the bearing hole 35a while passing it through the shaft hole 24, the frustoconical portion of the annular part 52 is guided by the frustoconical inner surface shape on the exit side of the shaft hole 24, causing the area where the annular part 52 is formed to elastically deform and reduce in diameter. The entire hinge pin 5 also deforms to reduce in diameter due to the cotter pin structure. As the annular part 52 protrudes from the exit of the shaft hole 24 and the entire hinge pin 5, including the annular part 52, returns to its original diameter, deviation of the hinge pin 5 outward to the left or right relative to the shaft hole 24 is prevented.
[0028] The bearing hole 35a has a frustoconical inner surface shape that gradually narrows in diameter from the opening towards the back, and the annular portion 52 of the hinge pin 5 is positioned near the enlarged opening of the bearing hole 35a. The hinge pin 5 is supported in a loosely fitted state with respect to at least one of the shaft hole 24 and the bearing hole 35a, allowing the lid 3 to be opened and closed relative to the container body 2, thus completing the assembly of the container 1.
[0029] In the container 1 assembled as described above, the stop pin 4 is fitted into the container body 2 so as not to rotate, leaving its tip exposed in the recess 25. It is also squeezed between the bottom surface 38 of the pin receiving hole 35b and the bottom surface 27 of the recess 25 and compressed in the direction of the axis 100. Furthermore, the tip 41 of the stop pin 4 and the bottom surface 38 of the pin receiving hole 35b are in surface contact with each other. In the free-stop mechanism of the container 1, the bottom surface 38 of the pin receiving hole 35b acts as a wall, and as the lid 3 is opened and closed, a frictional force is generated between the tip 41 of the elastic stop pin 4 and this wall, fixing the lid 3 in any rotational position. Furthermore, the tip 41 of the stop pin 4 and the pin receiving hole 35b are formed in a frustoconical shape where they are in surface contact with each other. In the free-stop mechanism of the container 1 according to the first embodiment, the frictional force between the outer circumferential surface of the tip 41 of the stop pin 4 and the inner circumferential surface of the pin receiving hole 35b is also utilized, as shown by the dashed circle 103 in Figure 4.
[0030] Thus, in the free-stop mechanism of the container 1 according to the first embodiment, frictional force is generated when the tip 41 of the stop pin 4, which is made of an elastic body compressed in the direction of the axis 100, presses against the bottom surface 38 of the pin receiving hole 35b. In other words, in a conventional free-stop mechanism, the hinge pin 5 is fixed to the axis hole 24, and a thin elastic body interposed between the outer surface of the hinge pin 5 and the inner surface of the bearing hole 35a is compressed in the radial direction, whereas in the first embodiment, an elastic body having sufficient thickness in the longitudinal direction is compressed. Therefore, in the container 1 according to the first embodiment, malfunctions of the free-stop mechanism due to deterioration of the elastic body over time, which was a problem with thin elastic bodies, can be suppressed.
[0031] Furthermore, conventional free-stop mechanisms require the use of an elastic body with sufficient thickness in the radial direction to suppress deterioration over time, but this is not necessary in the container 1 according to the first embodiment. Therefore, in the container 1 according to the first embodiment, it is possible to miniaturize the hinge mechanism while ensuring the reliability of the free-stop mechanism. Miniaturization of the hinge mechanism is suitable, for example, for compact containers that require further thinning. ===Second Example=== The components (2-6, 32) constituting the container 1 according to the first embodiment can be made from resin materials, with the exception of the mirror 32 made of glass or the like, and the stop pin 4 made of an elastic material. In other words, the container 1 is easy to recycle from the standpoint of the number of types of materials used in its components. On the other hand, in order to actually recycle the container 1, it is necessary to separate the components according to the material. In the case of the container 1, it is conceivable to attach the mirror 32 to the inside of the upper surface of the lid 3 using a water-soluble adhesive or the like during assembly. This allows the mirror 32 to be separated from the lid 3 by immersing the container 1 in water or the like. However, the stop pin 4 needs to be removed after separating the container body 2 and the lid 3. Furthermore, even after separating the container body 2 and the lid 3, the stop pin 4 must be pulled out using the tip that protrudes slightly from the recess 25 as a guide. Moreover, the stop pin 4 is firmly fitted into the recess 25 to prevent it from rotating together with the opening and closing of the lid 3, making it difficult to pull out.
[0032] Furthermore, in the container 1 according to the first embodiment, the hinge pin 5, which is a pin-shaped member used in the hinge mechanism, and the stop pin 4, which is a pin-shaped member used in the free-stop mechanism, are made up of separate parts, and it was necessary to arrange a total of four pin-shaped members (4, 5) coaxially during assembly. As a result, the assembly procedure could become complicated. Therefore, as the container according to the second embodiment, a compact container is proposed that allows for easy separation of parts according to the material and can be easily assembled even if there are many parts.
[0033] Figure 5 shows the container according to the second embodiment (hereinafter sometimes referred to as "container 11") in the open state, and Figures 6A and 6B show container 11 in the closed state. As shown in Figures 5, 6A, and 6B, the up / down, left / right, and front / back directions of container 11 are defined in the same way as container 1 according to the first embodiment. The distinction between solid and dotted lines for the directions of the container body 12 and the lid 13 is also the same. Therefore, Figures 5 and 6A are perspective views of container 11 as seen from the upper left front of the container body 12, and Figure 6B is a perspective view of container 11 as seen from the lower left rear. As shown in Figures 5, 6A, and 6B, container 11 has the same basic configuration and structure as container 1 according to the first embodiment, in which the lid 13 opens and closes with a hinge with the left-right axis 100 relative to the container body 12, but the free-stop mechanism and hinge configuration are different from those of container 1.
[0034] Figures 7A and 7B show a disassembled view of the container 11 in its closed state, broken down into its individual parts. Figures 7A and 7B are perspective views of each part, viewed from the upper left front and upper right rear, respectively. As shown in Figures 7A and 7B, the container body 12 and lid 13 of the container 11 are not integrally molded products, but are each composed of two parts. The container body 12 consists of a dish member 12a and a bottom plate 12b, and the lid 13 consists of a lid body part 13a and a top plate 13b. Figure 8A shows a perspective view of the dish member 12a viewed from the lower left rear, and Figure 8B shows a perspective view of the lid body part 13a viewed from the lower left rear. The configuration and assembly procedure of the container 11 will be explained below with reference to Figures 7A to 8B.
[0035] The dish member 12a has a rectangular box-shaped inner surface and is equipped with two storage compartments 121 that open upwards. Similar to the container body 2 in the first embodiment, end protrusions 122a and a central protrusion 122b are formed at both the left and right ends and in the center of the rear end. Therefore, notches 122c that open in the vertical direction are formed between the left and right end protrusions 122a and the central protrusion 122b. An axial hole 123 is formed in the end protrusion 122a, which penetrates in the left-right direction and through which a hinge pin 14 is inserted. In this way, in the container 11, almost all of the mechanical configuration of the container body 12 is concentrated in this dish member 12a. On the inner circumferential surface of the axial hole 123, multiple protrusions 124a extending in the direction of the axis 100 are formed at equal angular intervals around the axis 100. As a result, the space between adjacent protrusions 124a around the axis 100 forms an axial groove 124b.
[0036] A hinge pin 14 is inserted through the shaft hole 123. An enlarged view of the hinge pin 14 is shown within the dashed circle 105 in Figure 7A. The hinge pin 14 is a cotter pin with a slit 141 extending axially formed on its outer circumferential surface. Here, if the left and right inward ends of the hinge pin 14 are called the tip 142a and the left and right outward ends are called the base 142b, then three ribs 143 are formed around the axis of the hinge pin 14, projecting radially outward and extending in the direction of axis 100 from the base 142b to the tip 142a. The one slit 141 and the three ribs 143 are formed at 90° angular intervals around axis 100. Furthermore, an annular portion 144 similar to that of the hinge pin 5 in the container 1 of the first embodiment is formed on the tip 142a side of the hinge pin 14. Also, the tip 142a is flat, not sharp. The bottom plate 12b is a rectangular box shape that opens upward, and has a slit (hereinafter sometimes referred to as the "rear slit 122d") that opens upward, extends downward, and continues forward on the bottom surface. The bottom plate 12b functions as the outer casing of the container body, and when the dish member 12a is assembled, it covers the outer circumference and bottom surface of the dish member, while the rear slit 122d exposes the notch 122c of the dish member 12a to the outside. The container 11 is configured to maintain a closed state using the attractive force of magnets (15a, 15b) attached to the container body 12 and the lid 13, respectively. A wide rectangular hole (hereinafter sometimes referred to as the "holder mounting hole 125") is formed on the front end of the bottom plate 12b, and a magnet holder 16 that holds the magnet on the container body 12 side (hereinafter sometimes referred to as the "lower magnet 15a") is attached to this holder mounting hole 125. With the dish member 12a assembled to the base plate 12b, when the magnet holder 16 holding the lower magnet 15a is fitted into the holder mounting hole 125, the upper surface of the lower magnet 15a comes into contact with the lower surface on the front side of the dish member 12a. Therefore, as shown in Figure 5, the lower magnet 15a is not exposed to the outside even when the unit is open.
[0037] In the free-stop mechanism of the container 11, the hinge pin 14 is configured to also function as the stop pin 4 in the container 1 according to the first embodiment. The lid 13 has a wall surface 174 that contacts the tip 142a of the hinge pin 14 fixed to the container body 12 to generate frictional force. This wall surface 174 is part of a wall member 17 made of an elastic material that is detachably attached to the lid body 13a. The wall member 17 has a rectangular plate-shaped portion (hereinafter sometimes referred to as "base portion 171") with the vertical direction as the normal and the horizontal direction as the long side, and two portions (hereinafter sometimes referred to as "wall portion 172") that form the wall surface 174 are formed on the lower surface, facing each other in the left-right direction. In addition, crank-shaped portions (hereinafter sometimes referred to as "gripping portion 173") are formed at both the left and right ends of the base portion 171, which are bent upward when viewed from the front-rear direction and then protrude outward to the left and right.
[0038] The lid 13 consists of a lid body portion 13a, which contains most of the mechanical components of the lid 13, and a top plate 13b, which is the outer casing of the lid body portion 13a. At the rear end of the lid body portion 13a, two engaging protrusions 131 are formed that engage with notches 122c formed between the left and right end protrusions 122a and the central protrusion 122b of the dish member 12a. The two engaging protrusions 131 have recesses (hereinafter sometimes referred to as "wall storage portion 133") formed on the left and right inner end faces 132a, which, when viewed from the left and right directions, have a shape consisting of a rectangle with a downward-convex semicircle at the lower end. In addition, the engaging protrusions 131 have holes (hereinafter sometimes referred to as "bearing holes 134") that penetrate from left to right and have openings into the wall storage portion 133, and these holes are formed coaxially with the semicircle at the lower end of the wall storage portion 133. Furthermore, a rectangular through-hole (hereinafter sometimes referred to as the "wall insertion hole 135") is formed at the upper end of the wall storage section 133, which connects to the upper surface of the lid body section 13a. The wall portion 172 of the wall member 17 is then inserted into the wall insertion hole 135 and positioned inside the wall storage section 133.
[0039] The lid body 13a has a frame-shaped portion (hereinafter sometimes referred to as the "mirror mounting frame 136") on its upper surface into which a rectangular, planar mirror 32 is fitted. Inside the mirror mounting frame 136, a rectangular opening (hereinafter sometimes referred to as the "mirror exposure window 137") is formed to expose the mirror surface of the mirror 32 downwards. Furthermore, a frame-shaped portion (hereinafter sometimes referred to as the "magnet mounting frame 138") is formed on the front upper surface of the lid body 13a, into which a magnet (hereinafter sometimes referred to as the "upper magnet 15b") that attracts the lower magnet 15a when the lid is closed is mounted. Therefore, as shown in Figure 5, the upper magnet 15b, like the lower magnet 15a, is not exposed to the outside even when the lid is open.
[0040] The top plate 13b is a rectangular box shape with a top surface that opens downwards, and it covers the upper part of the lid body 13a as the outer casing of the lid body 13. The rear surface of the top plate 13b has a rectangular opening (hereinafter sometimes referred to as the "coin hole 139") that connects the inside and outside. In Figures 6B and 7B, the coin hole 139 is exposed to the outside; however, to improve the aesthetic appearance of the container 11, a cover that can be detachably attached to the coin hole 139 may be provided. The use of this coin hole 139 will be described later.
[0041] The container 11, having the above configuration, can be easily assembled without the use of jigs or tools, as each part engages with the others using a well-known snap-fit mechanism. The assembly procedure for the container 11 is as follows: First, the mirror 32, the upper magnet 15b, and the wall member 17 are attached to the lid body 13a. Next, the engaging projection 131 of the lid body 13a is engaged with the notch 122c of the dish member 12a so that the shaft hole 123 and the bearing hole 134 are coaxial. In this state, the hinge pin 14 is inserted into the shaft hole 123 and then into the bearing hole 134, using the left and right outward openings as entrances. At this time, the hinge pin 14, similar to the hinge pin 5 in the first embodiment, elastically deforms to reduce in diameter at the exit of the shaft hole 123, and the tip 142a side, including the annular portion 144, protrudes from the exit of the shaft hole 123, preventing the hinge pin 14 from deviating outward to the left or right relative to the shaft hole 123. In addition, the rib 143 of the hinge pin 14 engages with the groove 124b in the shaft hole 123, preventing the hinge pin 14 from rotating relative to the dish member 12a. On the other hand, on the lid body portion 13a side, the hinge pin 14 is inserted into the bearing hole 134 in a loosely fitted state. This connects the lid body portion 13a to the dish member 12a in a rotatable manner. Next, the dish member 12a and the bottom plate 12b are integrated by ultrasonic welding or the like, and the top plate 13b is fitted onto the lid body portion 13a. Then, the magnet holder 16, which holds the lower magnet 15a, is attached to the holder mounting hole 125 of the bottom plate 12b to complete the container 11.
[0042] Figure 9 shows a view of the cross-section of the container 11 in its closed state, as seen from the rear, when the container is cut by a plane that includes the axis 100 and extends in both the vertical and horizontal directions. Figure 9 corresponds to the area indicated by the dotted cylinder 104 in Figures 6A and 6B. The structure and operation of the free-stop mechanism in the container 11 will be explained below with reference to Figures 7A to 9.
[0043] In the container 11 according to the second embodiment, a resin hinge pin 14 also serves as a stop pin, and a free-stop mechanism is realized by utilizing the frictional force between the tip 142a of the hinge pin 14 and the wall portion 172 of the wall member 17 made of an elastic material. In the container 11, the hinge pin 14 is fitted into the dish member 12a so as not to rotate, and the tip 142a has an engaging projection that protrudes from the bearing hole 134 in the wall storage portion 133. The wall portion 172 of the wall member 17 made of an elastic material is arranged in the wall storage portion 133. The left and right outer surfaces of the wall portion 172 are called wall surfaces 174, and the tip 142a of the hinge pin 14 is in contact with these wall surfaces 174. The left-right thickness t of the wall portion 172 is greater than the left-right depth d of the wall storage portion 133, and the left and right inner surfaces 175 of the wall portion 172 protrude further inward than the left and right inner surfaces 132a of the engaging projection 131, so that the wall portion 172 is sandwiched between the bottom surface 132b of the wall storage portion 133 and the left and right outer end surfaces 126 of the central projection 122b of the dish member 12a. As a result, the wall portion 172 is compressed in the axial direction 100 by the hinge pin 14. Furthermore, when the lid 13 is opened and closed, the wall portion 172 rotates relative to the hinge pin 14 and the left and right end faces 126 of the central protrusion 122b with friction. However, in the second embodiment, the periphery of the wall storage portion 133 is frame-shaped, and the wall portion 172 is arranged within this frame. This prevents the wall portion 172 from twisting or shifting position when the lid 13 is opened and closed. In other words, the container 11 can be reliably opened and closed so that the lid 13 can be fixed to the container body 12 at any rotational position.
[0044] Thus, in the free-stop mechanism of the container 11 according to the second embodiment, frictional force is generated when the wall portion 172 of the wall member 17, which is made of an elastic material compressed in the direction of the axis 100, presses against the hinge pin 14. Furthermore, the wall portion 172 can be set to a thickness sufficient to prevent malfunction of the free-stop mechanism due to deterioration of elasticity over time. In addition, since the hinge pin 14 also serves as a stop pin, the container 11 is suitable for miniaturization. In particular, it is possible to reduce the size in the left-right direction.
[0045] Furthermore, the container 11 is suitable for recycling because the wall member 17 is configured to be detachable from the lid body 13a. The specific disassembly procedure for the container is as follows: First, insert a coin or the like into the coin hole 139 of the top plate 13b, and use this coin as a lever to remove the top plate 13b from the lid body 13a. This exposes the base 171 of the wall member 17. Next, using either of the gripping parts 173 on both the left and right ends of the base 171 as a handhold, lift the wall member 17 upwards, pull the wall 172 out of the wall storage section, and remove the wall member 17 from the lid body 13a. Also, remove the mirror 32 and the upper magnet 15b, which are exposed to the outside by removing the top plate 13b. Furthermore, remove the magnet holder 16 from the bottom plate 12b, and remove the lower magnet 15a from the magnet holder 16. Thus, the container 11 can be easily disassembled into an elastic wall member 17, a glass mirror 32, metal magnets (15a, 15b), and other parts made of resin, making it suitable for recycling.
[0046] In the first embodiment, all parts of the container 11 were configured to engage with each other by snap-fitting, but the mirror 32 and magnets (15a, 15b) may be bonded with a water-soluble adhesive or the like. In this case, if the lower magnet 15a is placed on the upper surface of the dish member 12a, disassembly of the container body 12 is unnecessary. Similar to the first embodiment, if the closed state is maintained by a hook and an engaging projection, there is no need to use magnets (15a, 15b). In any case, in the second embodiment, the container 11 has a free-stop mechanism that uses the frictional force generated at the contact surface between the tip 142a of the hinge pin 14, which is a pin-shaped member, and the wall portion 172, so that the wall member 17 that makes up the wall surface 174 can be easily attached and detached. ===Other Examples=== Although the containers (1,11) according to the embodiments have been described above, it goes without saying that the present invention is not limited to the above embodiments and can be modified in various ways without departing from the spirit of the invention. Furthermore, the above embodiments have been described in detail in order to explain the present invention in an easy-to-understand manner and are not necessarily limited to those having all the configurations described. In addition, it is possible to add, delete, or replace some of the configurations of the above embodiments with other configurations. For example, in the first embodiment, the wall surface that abuts the tip 41 of the stop pin 4 was the bottom surface 38 of the pin receiving hole 35b. However, the pin receiving hole 35b may be omitted, and the left and right inner surfaces 37 of the engaging projection 34 may be made flat surfaces, and the tip 41 of the stop pin 4 may be made to abut these flat surfaces. In any case, it is sufficient that the engaging projection 34 is provided with a surface equivalent to a wall surface.
[0047] The free-stop mechanism only requires that at least one of the pin-shaped member and the wall surface be made of an elastic material. For example, in the first embodiment, a plate-shaped elastic material can be placed on the bottom surface of the pin receiving hole 35b. In the second embodiment, the container 11 had a free-stop mechanism made of a resin hinge pin 14 that also served as a stop pin and a detachable wall surface member 17 made of an elastic material, taking into consideration the ease of sorting. Naturally, if one is willing to make some sacrifices to the ease of sorting, it is easy to replace the hinge pin 14 that also serves as a stop pin with an elastic material such as an elastomer.
[0048] Furthermore, if the central projection 23b is formed facing the end projection 23a via a notch, the central projection 23b is not limited to one, but may be divided into left and right sections. That is, two central projections 23b may be formed facing each other on the left and right sides at the center of the rear end of the container body 2, and a fitting recess 25 may be formed in each of the two central projections 23b.
[0049] In the second embodiment, the hinge pin 14 was fixed to the container body 12 in a non-rotatable manner by an engagement structure between the rib 143 and the groove 124b in the shaft hole 123, but it may also be fixed in the shaft hole 123 using an adhesive or the like. For the stop pin 4 in the first embodiment, instead of inserting it into the fitting recess 25 in a forcefully fitted state, a groove 124b may be provided in the fitting recess 25 and a rib 143 may be formed around the stop pin 4, similar to the second embodiment. In any case, it is sufficient that the pin-shaped members (4,14) constituting the free-stop mechanism are fixed to either the container body (2,12) or the lid (3,13) in a non-rotatable manner.
[0050] The container 1 according to the first embodiment can be modified so that the hinge pin 5 also serves as the stop pin 4. Figures 10, 11A, and 11B show an example of an embodiment in which the hinge pin 64 also serves as the stop pin in the first embodiment (hereinafter sometimes referred to as the "first modified example"). Here, Figure 10 is an exploded perspective view showing the configuration of the container 61 according to the first modified example. Figures 11A and 11B are views of the cross-section of the container 61 in the closed state, when it is cut by a plane including the axis 100 in the vertical and horizontal directions, as seen from the rear. These figures are for explaining the free-stop mechanism in the container 61 according to the first modified example and correspond to the area indicated by the dotted cylinder 106 in Figure 10.
[0051] As shown in Figure 10, the container 61 according to the first modified example has a central projection 621 that protrudes rearward from the center of the left and right rear ends of the container body 62. In other words, in the container body 62 of the first modified example, the end projections 23a are omitted from the container body 2 of the first embodiment. Also, engaging projections 631 are formed at both the left and right ends of the rear end of the lid 63 so as to protrude downward. Therefore, when the container body 62 and the lid 63 are connected by a hinge, the central projection 621 is held in place by the left and right engaging projections 631 on the lid 63.
[0052] The left and right end faces 622 of the central projection 621 have bottomed holes (hereinafter sometimes referred to as "bearing holes 623") that are coaxial with the hinge shaft 100. In addition, the engaging projection 631 of the lid 63 has through holes (hereinafter sometimes referred to as "shaft holes 633") that connect the left and right outer end faces 632a and the left and right inner end faces 632a, and are formed coaxial with the hinge shaft 100. Furthermore, the inner surface of the shaft holes 633 has protrusions 634 that extend in the direction of the shaft 100, similar to the shaft holes 123 in the second embodiment, and grooves are formed between adjacent protrusions 634 around the shaft 100. The hinge pin 64, which also serves as a stop pin, has the same structure as the hinge pin 14 in the second embodiment. In other words, the hinge pin 64 is a cotter pin with a slit 642 formed on it, and its outer circumference has a rib 641 that protrudes radially outward and extends in the direction of the axis 100, and an annular portion 643 that protrudes radially outward and revolves around the axis 100.
[0053] Next, the free-stop mechanism in the container 61 according to the first modified example will be described with reference to Figures 11A and 11B. Note that the configuration of the free-stop mechanism differs between Figure 11A and Figure 11B. In general terms, the configuration of the hinge pin 64 and the wall surfaces (624, 651) that abut the tip 644a of the hinge pin 64 differs slightly between the free-stop mechanism shown in Figure 11A and the free-stop mechanism shown in Figure 11B.
[0054] In the free-stop mechanism shown in Figure 11A, the hinge pin 64 is made of an elastic material such as an elastomer. The hinge pin 64 is inserted through the shaft hole 633, and the region from the annular portion 643 to the tip 644a is inserted into the bearing hole 623. The inner openings on the left and right of the shaft hole 633 are smaller in diameter than the outer openings on the left and right, preventing the hinge pin 64 from deviating outward relative to the shaft hole 633. In addition, grooves 634 are formed on the inner surface of the shaft hole 633 between adjacent protrusions 633 around the shaft 100, and the ribs 641 of the hinge pin 64 engage with these grooves 634. As a result, the hinge pin 64 is unable to rotate relative to the cover 63.
[0055] The hinge pin 64 is inserted into the bearing hole 623 with its tip 644a loosely fitted, allowing it to rotate relative to the container body 62. The hinge pin 64 has its tip 644a in contact with the bottom surface 624 of the bearing hole 623 and is compressed in the direction of the axis 100, being held between the bottom surface 624 of the bearing hole 623 and the left and right inner end faces 623 of the engaging projection 631. In the free-stop mechanism of the container 61 shown in Figure 11A, the bottom surface 624 of the bearing hole 623 acts as a wall, and as the lid 63 opens and closes, a frictional force is generated between the tip 644a of the elastic hinge pin 64 and this wall, fixing the lid 63 in any rotational position.
[0056] On the other hand, in the free-stop mechanism shown in Figure 11B, the hinge pin 64 is made of resin. A disc-shaped elastic body (hereinafter sometimes referred to as "wall member 65") with thickness in the direction of the axis 100 is placed on the bottom surface 624 of the bearing hole 623. The tip 644a of the resin hinge pin 64 abuts against this wall member 65, and the wall member 65 is compressed in the direction of the axis 100 and held between the bottom surface 624 of the bearing hole 623 and the tip 644a of the hinge pin 64. Therefore, in the free-stop mechanism of the container 61 shown in Figure 11B, the surface of the wall member 65 that the tip of the hinge pin 64 abuts against becomes the wall surface 624, and as the lid 63 is opened and closed, a frictional force is generated between the tip 644a of the hinge pin 64 and this wall surface 624, fixing the lid 63 at any rotational position.
[0057] The container body 12 in the second embodiment may be a single molded product, similar to the container body 2 in the first embodiment. Furthermore, although the container 11 in the second embodiment had a top plate 13b covering the upper part of the lid body 13a, the structure and configuration are not limited to those described above, as long as the wall member 17 can be attached detachably. Figure 12A shows an example in which the lid 13 is modified from the container 11 in the second embodiment (hereinafter sometimes referred to as the "second modified example"). As shown in Figure 12A, in the lid 113 of the second modified example, the mounting structure for the wall member 17 is formed on the upper rear end side of the integrated lid 113, and the mirror 32 and upper magnet 15b are attached to the lower surface of the lid 113. Note that in the lid 113 shown in Figure 12A, the wall member 17 is exposed to the outside, so as shown in Figure 12B, a cover 114 that covers the wall member 17 may be attached detachably to the lid 113 by a snap fit or the like.
[0058] The wall member 17 does not necessarily have to have the left and right wall portions 172 integrally formed on a single base portion 171. Two wall members 17, each with a single wall portion 172, may be used.
[0059] The relative positions of the container body (2, 12, 62) and the lid (3, 13, 63) may be reversed. For example, end protrusions (23a, 122a) and central protrusions (23b, 122b) may be provided on the lid 3 side in the first embodiment or on the lid body portion 13a side in the second embodiment. Furthermore, an engaging protrusion 34 may be provided on the container body 2 in the first embodiment, or an engaging protrusion 131 and a mounting structure for the wall member 17 may be provided on the dish member 12a in the second embodiment. Similarly, in the first modified example, a central protrusion 621 may be provided on the lid 63 side and an engaging protrusion 631 may be provided on the container body side.
[0060] In the container 11 according to the second embodiment, the container body 12 was formed by integrating a dish member 12a and a bottom plate 12b by ultrasonic welding or the like, but the container body 12 may also be constructed by snap-fitting the dish member 12a into the bottom plate 12b.
[0061] The engagement structure between the container body 2 and the lid 3 in the container 1 of the first embodiment is not limited to a hook 33 and an engaging projection 22; for example, magnets (15a, 15b) may be used, as in the second embodiment. Similarly, the engagement structure between the lid 13 and the container body 12 in the container 11 of the second embodiment can be changed to a hook 33 and an engaging projection 22 instead of magnets (15a, 15b). Of course, since the closed state can be maintained by the free-stop mechanism, the engagement structure between the lid (3, 13) and the container body (2, 12) is not an essential configuration. Naturally, the present invention can also be applied to containers other than compact containers. [Explanation of symbols]
