  The hinge structure 10 of the present invention and the container 1 of the present invention using the hinge structure 10 will be described below in detail with reference to the drawings. 1 is a perspective view of a container 1 of the present invention assumed to be used as a cosmetic container, FIG. 2 is a plan view, FIG. 3 is a side view, and FIG. 4 is an enlarged plan view of a hinge structure 10 of the present invention. FIG. 5 is an enlarged sectional view of the hinge structure 10.

  1-3, the container 1 of the present invention is composed of a hinge structure 10, a container body 2, and a lid 3. The hinge structure 10, the container body 2, and the lid 3 are made of resin. The lid 2 and the lid 3 are integrally connected by the hinge structure 10. The material of the container 1 may be any material that elastically deforms the elastic deformation portion 12 of the hinge structure 10, and a resin or the like used for a general container can be used. The lid 3 is hingedly engaged with the container body 2 so as to be opened and closed by the hinge structure 10. As shown in FIG. 3, the container 1 is integrally formed with the lid 3 opened 180 ° with respect to the container body 2.

  As shown in FIG. 2, the said container main body 2 has a substantially rectangular planar shape, and the two accommodating parts 4 are formed in the inside as a space in which cosmetics are accommodated. The shape, the number, and the like of the accommodating portion 4 can be appropriately changed according to the item to be accommodated, and are not limited to the present embodiment. The container body 2 is provided with an engaging projection 5 for fixing the lid 3 in a closed state.

  The lid 3 is sized to cover and close the container body 2, and is provided with an engagement protrusion 6 that engages with the engagement protrusion 5 of the container body 2. The container 3 is fixed to the container body 2 in a state where the lid 3 is closed by getting over and engaging with the engagement protrusion 5 of the container body 2. The structure for fixing the lid 3 may be other than the engaging projection, and is not particularly limited. The structure for fixing the lid 3 may not be used.

  As shown in FIGS. 1 and 2, a resin mirror 7 is provided on the inner surface of the lid 3. When the container 1 is used as a cosmetic container, makeup can be made using the cosmetic stored in the storage section 4 of the container body 2 while looking at the resin mirror 7. Further, since the resin mirror 7 can be treated as combustible waste, when the container 1 of the present invention is discarded, it can be disposed without removing the resin mirror 7, so that the disposal can be easily performed. It is also possible to use the container 1 of the invention as a disposable container. A container not provided with the resin mirror 7 or a container provided with a mirror other than the resin mirror is also possible, and can be appropriately selected according to the use of the container 1.

  Next, the hinge structure 10 of the present invention will be described in detail. The hinge structure 10 is integrally connected to the container body 2 so that the lid 3 can be opened and closed, and is integrally formed with the container body 2 and the lid 3. As shown in FIG. 4, the hinge structure 10 includes a hinge main body 11 and two elastic deformation portions 12 provided at both ends of the hinge main body 11.

  In the container 1, the container body 2, the lid 3, and the hinge structure 10 are integrally formed with the lid 3 opened. Therefore, the hinge is based on the state in which the lid 3 is opened. The structure 10 will be described. The hinge body 11 connects the container body 2 and the hinge body 11, and as shown in FIG. 4, when the lid 3 is closed, the fold line between the container body 2 and the hinge body 11 The first broken line 13 and the lid 3 and the hinge main body 11 are connected to each other, and when the lid 3 is closed, the second bent line 14 is formed as a broken line between the lid 3 and the hinge main body 11. As shown in FIG. 4, the first fold line 13 and the second fold line 14 are provided in parallel to each other, and the planar shape of the hinge main body 11 viewed from above is as shown in FIG. The first broken line 13 and the second broken line 14 form a rectangle that forms two sides in the longitudinal direction.

  As shown in the cross-sectional view of FIG. 5, the cross-sectional shape of the hinge main body 11 is a substantially trapezoidal shape with the long side up, but when the hinge main body 11 itself opens and closes the lid 3, Since the container 1 is bent by the first fold line 13 and the second fold line 14 except for the vicinity of the connection portion with the elastic deformation portion 12, the cross section of the hinge main body portion 11 is obtained. The shape may be any shape as long as it does not hinder the bending of the container 1. The first bent line 13 and the second bent line 14 have thicknesses that function as bent lines and satisfy durability against repeated bending by opening and closing the lid 3.

  As shown in FIG. 4, the two elastic deformation portions 12 connect the container main body 2 and the elastic deformation portion 12, and close the lid 3 between the container main body 2 and the elastic deformation portion 12. When the lid 3 and the elastically deforming portion 12 are connected to each other, the lid 3 and the elastic deformation portion 12 are connected to each other by connecting the lid 3 and the elastically deformable portion 12. Each of the second bent lines 16 has a fourth bent line 16 which is bent at the end of the second bent line and extended. The third bent line 15 and the fourth bent line 16 function as bent lines, have durability against repeated bending by opening and closing the lid 3, and have strength that does not break due to elastic deformation of the elastic deformation portion 12. It is set as such thickness.

  As shown in FIG. 4, the planar shape of the elastic deformation portion 12 is substantially trapezoidal, and a short side portion of the substantially trapezoid shape becomes a connection portion with the hinge body 11, and a long side portion of the substantially trapezoid shape is an end. The planar shape of the hinge structure 10 is a shape in which a trapezoid (elastically deforming portion 12) is provided at both ends of a rectangle (hinge body portion 11). The cross-sectional shape of the elastically deforming portion 12 is a substantially trapezoidal shape with the connecting portion to the hinge main body portion 11 being the same as the hinge main body portion 11 and having a long side up, as shown in FIG. Since it has a substantially mountain shape, the cross-sectional shape changes from a substantially trapezoidal shape to a substantially mountain shape. By having such a shape, the elastic deformation portion 12 is elastically deformed when the lid 3 is opened and closed, and an elastic force is generated.

  The hinge structure 10 is connected to the container body 2 by the first broken line 13 and the two third broken lines 15, and is connected to the lid 3 by the second folded line 14 and the two fourth folded lines 16. Therefore, as shown in FIG. 6, when the lid 3 is opened and closed, the container 1 is bent at two locations.

  The container body 2 and the lid 3 respectively have inclined surfaces 8 and 9 at the connection portion with the hinge structure 10, and the first bent line 13 and the second bent line are formed at lower ends of the inclined surfaces 8 and 9. 14 is connected. The inclined surface 8 of the container body 2 is bent along the first bent line 13 and the two third bent lines 15, and the inclined surface 9 of the lid 3 is the second bent line 14 and the two fourth bent lines 16. It is bent along. In addition, the inclination angle of the inclined surfaces 8 and 9 is determined by the opening / closing angle of the lid 3 and the angle of the mountain-shaped inclination at the end of the elastic deformation portion 12, and may be vertical.

  Since the container 1 of the present invention is integrally formed with the lid 3 being opened 180 ° with respect to the container body 2, the elastically deforming portion 12 of the hinge structure 10 has the lid 3 opened. It is in an initial state, and elastic force is not acting at this time. Accordingly, when a force acts on the container 1 in the direction of closing the lid 3 from the state shown in FIGS. 1 to 3, the elastic deformation portion 12 is deformed, so that an elastic force for returning to the original shape acts. The container 1 is held in a state where the lid 3 is opened by the elastic deformation portion 12. Therefore, even when the lid 3 is not fixed by the engagement protrusions 5 and 6, the lid 3 can be held in a closed state.

  Next, the operation of the hinge structure 10 when the lid 3 is opened and closed will be described with reference to FIG. At this time, it is assumed that the container body 2 and the lid 3 are moved around the hinge structure 10.

  In the present embodiment, as shown in FIG. 3, description will be made using a form in which the lid 3 opens at 180 ° with respect to the container body 2 when the lid 3 of the container 1 is opened. In FIG. 6A, the container body 2 is connected to the left side of the hinge structure 10 and the lid 3 is connected to the right side in the state where the lid 3 is opened. From this state, in order to close the lid 3, the lid 3 is rotated to the left with the second broken line 14 as an axis, and at the same time, the container body 2 is rotated to the right with the first bent line 13 as an axis. .

  At this time, the hinge body portion 11 of the hinge structure 10 is hardly deformed (the connecting portion with the elastic deformation portion 12 is somewhat deformed). On the other hand, in the elastic deformation portion 12 of the hinge structure 10, the third broken line 15 pivots with the end portion of the first bent line 13 as a fulcrum, and the fourth bent line 16 is connected to the second bent line 14. Since the third bent line 15 and the fourth bent line 16 move so as to form a part of the surface of the cone, the elastic deformation part 12 is elastically deformed. The end portion moves upward (in the case of FIG. 6) with respect to the main body portion 11. At this time, the connecting portion between the elastic deformation portion 12 and the hinge main body portion 11 forms a broken line, and the elastic deformation portion 12 moves upward (in the case of FIG. 6) with respect to the main body portion 11. Will do.

  FIG. 6B shows the hinge structure 10 in a state in which the lid 3 is being closed (the lid 3 and the container body 2 are each rotated by 45 °). Since the deformed portion 12 is deformed so that the cross section of the end portion spreads in the horizontal direction, an elastic force is exerted on the elastic deformable portion 12 to return to the original shape (the cover 3 is opened). doing. And since the state of FIG.6 (b) is the state which the said elastic deformation part 12 deform | transformed most horizontally, when it adds to the direction which closes the said container main body 2 and the said lid | cover 3, The elastic force that the elastic deformation part 12 tries to return to its original shape acts in the direction of closing the lid 3, so that the container body 2 and the lid 3 rotate 45 ° in the direction of closing, respectively. As shown in FIG. 6C, the end of the elastic deformation portion 12 returns to its original shape, and the lid 3 is completely closed. Thus, when the lid 3 is closed, the container main body 2 and the lid 3 are rotated by 90 ° about the first fold line 13 and the second fold line 14, respectively.

  In the container 1 with the lid 3 closed as shown in FIG. 6C, when a force is applied to the lid 3 and the container body 2 in the direction of opening the lid 3, the elastic deformation portion 12 is deformed. Since the elastic force tries to return to the original shape, the elastic force acts in the direction in which the lid 3 is closed by the elastic deformation portion 12. Therefore, as long as no force is applied to the container 1 with the lid 3 closed until the state shown in FIG. 6B, the lid 3 cannot be completely opened even if an inadvertent impact is applied. Therefore, the container 1 can maintain a state in which the lid 3 is closed.

  In the container 1 with the lid 3 closed as shown in FIG. 6B, the end of the inclined surface 8 of the container body 2 and the end of the inclined surface 9 of the lid 3 are the same as those of the hinge structure 10. The elastic deformation portion 12 is in contact with the end portion of the mountain-shaped cross section. Thereby, the sealing degree of the said container 1 can be raised. As described above, since the end portions of the inclined surfaces 8 and 9 and the end portion of the elastically deforming portion 12 come into contact with each other, the tilting is performed when the lid 3 is opened as shown in FIG. The side of the end of the surface 8 and one side of the mountain of the end of the elastically deforming portion 12 are the same length and are arranged to form 90 °, and the side of the end of the inclined surface 9 The elastic deformation portion 12 has the same length as one side of the chevron and is arranged to form 90 °. The end of the inclined surface 8 of the container body 2 and the end of the inclined surface 9 of the lid 3 do not need to be in full contact with the end of the elastic deformation portion 12 of the hinge structure 10.

  When a force is applied to the container 1 in a state in which the lid 3 is closed, the container 1 is again in the state shown in FIG. 6B. From this state, the container body 2 and the lid 3 are further turned on. When a force is applied in the opening direction, the elastic deformation portion 12 returns to its original shape and position as shown in FIG. 6A, and the lid 3 is completely opened. Become. At this time, the elastic deformation portion 12 is subjected to an elastic force to return to the original shape from the middle, and the container body 2 and the lid 3 move in the opening direction.

  Since the state in which the lid 3 is opened at 180 ° with respect to the container body 2 is an initial state of the elastic deformation portion 12, unless the force is applied to the container 1 to the state shown in FIG. The container 1 can maintain a state where the lid 3 is opened at 180 ° by an elastic force. Even if a force is applied to the container 1 in a direction to open the lid 3 at 180 ° or more, the elastic force acts on the elastic deformation portion 12 to return to the original shape. Can hold the lid 3 in an open state of 180 °.

  Although the movement of the hinge structure 10 has been described on the assumption that the lid 3 and the container body 2 are rotated with respect to the hinge structure 10, when the lid 3 is actually opened, the container body 2 is In the fixed state, the lid 3 is moved in the closing direction. At this time, the elastic deformation portion 12 is deformed while the hinge structure 10 is rotated with respect to the container body 2, and the lid 3 is moved so as to be rotated with respect to the hinge structure 10. However, the movement of the lid 3 and the container body 2 with respect to the hinge structure 10 is the same as that shown in FIG.

  As described above, the hinge structure 10 of the present invention is a simple structure in which the elastic deformation portions 12 are provided at both ends of the hinge main body portion 11, and stably holds the lid 3 of the container 1 in the opened state and the closed state. It becomes possible to do. The container 1 of the present invention using the hinge structure 10 is stable in a state where the lid 3 is opened at a predetermined angle by integrally forming the hinge structure 10 with the container body 2 and the lid 3. It is also possible to reduce the manufacturing cost.

  The container 1 of the present invention can change the angle when the lid 3 is fully opened by changing the positional relationship between the hinge structure 10 and the container body 2 and the lid 3. FIG. 7 shows the container 1 when the lid 3 is fully opened at 160 ° with respect to the container body 2.

  The container 1 having a configuration in which the lid 3 is opened at 160 ° is rotated 80 ° around the first fold line 13 and the second fold line 14 from the state shown in FIG. When moved, the lid 3 can be closed. FIG. 7B shows a state in the middle of closing the lid 3, and the container body 2 and the lid 3 are rotated by 40 ° about the first broken line 13 and the second folded line 14, respectively. It is the state made to do. When the container body 2 and the lid 3 are further rotated by 40 ° about the first fold line 13 and the second fold line 14, respectively, from the state of FIG. 7 (b), as shown in FIG. 7 (c), The lid 3 is closed. In order to open the lid 3, the container body 2 and the lid 3 are rotated by 80 ° about the first broken line 13 and the second folded line 14 in the opening direction of the lid 3, respectively. After the state of (b), as shown in FIG. 7 (a), the lid 3 can be completely opened.

  In the container 1 of the present invention, the hinge structure 10, the container body 2, and the lid 3 are integrally formed with the lid 3 opened, whereby the opening angle of the lid 3 is determined. Therefore, the angle at which the lid 3 is opened can be changed by changing the angle between the container body 2 and the lid 3 when the container 1 is integrally formed. At this time, in accordance with the opening angle of the lid 3, the angles of the inclined surfaces 8, 9 of the container body 2 and the lid 3, the positional relationship between the hinge body 11 and the elastic deformation portion 12 of the hinge structure 10, By setting a mountain shape or the like at the end of the elastic deformation portion 12, the angle at which the lid 3 of the container 1 is opened can be set appropriately.

  The cross-sectional shape of the end portion of the elastic deformation portion 12 of the hinge structure 10 is a mountain on which an elastic force is applied to return to the original shape when deformed as shown in FIGS. 6B and 7B. Any shape may be used, and various shapes such as a mountain shape made of a straight line, a curved mountain shape made of a curve, a mountain shape combining a straight line and a curve, and an inverted U shape can be used.

  Although the container 1 of the present invention has been described assuming that it is used as a cosmetic container, it can also be used for other purposes. At that time, it is not necessary to integrally mold the container body 2 and the lid 3 with the hinge structure 10, and a part of the container body 2 and the lid 3 (part not connected to the hinge structure 10) is separately molded. It is also possible to attach it later as a member. For example, another member such as an intermediate dish can be attached to the accommodating portion 4 of the container body 2.
