JP 2008-297010 A

  In such a container, the lid body is closed such that the side wall provided on the lid body and the inner ring sandwich the opening of the container body. At this time, an inner ring is inserted into the inner wall of the opening in order to improve the sealing performance. For this reason, when the lid is opened and closed, the side walls and the inner ring come into contact with the opening almost simultaneously, and the lid receives a resistance force. For this reason, a large force is required to open and close the lid, and it may be difficult to open or close, or the force to push in when closing the lid may be insufficient, resulting in insufficient sealing.

  An object of the present invention is to improve the ease of opening and closing of a lid and the certainty of sealing by the lid in a container having a lid connected to the container body by a hinge.

One aspect of the present invention is a container that includes a cylindrical container body, and a lid body that is connected to the container body by a hinge and that can be opened and closed with respect to the opening of the container body. A body rib having an outer diameter larger than the outer diameter of the opening and an inner diameter larger than the inner diameter of the opening is formed on at least a part of the opening, and the opening sandwiches the opening from the inside and the outside in the closed state. An inner ring and a side wall are formed at each position, and the inner wall has a smaller inner diameter than the other part on the inner side surface, and has a lid rib that the main body rib contacts and gets over when the lid body is opened and closed. The outer diameter is smaller than the inner diameter of the main body rib, and in the closed state of the lid body, the first gap is provided between the main body rib and the lid body without contacting the main body rib when the lid body is opened and closed. When closing the lid, the body rib touches the lid rib and gets over After the opening is sealed inner ring in contact with the opening, when opening the lid, after the inner ring away from the opening, the main rib rides over the lid ribs. In addition, the portion of the side wall closer to the lid body than the lid rib on the inner side surface has an inner diameter larger than the maximum value of the outer diameter of the main body rib. A second void is present. When closing the lid, the first gap accommodates the main body rib that is pressed from the lid rib and displaced toward the inner ring before the main body rib passes over the lid rib, and the second gap closes the lid. At this time, after the main body rib passes over the lid rib, the main body rib is released from the pressed state and biased by being displaced toward the inner ring, and accommodates the main body rib displaced toward the side wall.

  Further, the main body rib may be formed at least at a position opposite to the hinge of the opening.

  Further, the force required to open and close the lid may not have two or more maximum values with respect to the progress of opening and closing.

  Further, the force required to open and close the lid may be constant for a predetermined period.

  In addition, the lid further includes a flange portion connected to the outer side surface of the side wall at a position opposite to the hinge, and the lid portion is configured so that the thickness of the distal end portion is smaller than the thickness of the connection portion with the side wall. The upper surface that is the top surface side of the body may be inclined.

  Moreover, the recess may be formed in the lower surface facing the upper surface.

  The present invention can improve the ease of opening and closing of the lid and the certainty of sealing by the lid in a container having a lid connected to the container body by a hinge.

  A container 100 according to an embodiment of the present invention will be described. The container 100 includes a cylindrical container body 101 and a lid body 111. The container body 101 and the lid body 111 are connected to each other by a hinge 121. FIG. 1 is a vertical cross-sectional view of the container 100 when the lid 111 is in a closed state by a surface passing through the central axis of the container main body 101 and the hinge 121. FIG. 2 is a top view of the container body 101 and the lid body 111 when the lid body 111 is opened at 180 °. FIG. 3 is a partially enlarged view of the longitudinal sectional view shown in FIG.

  A main body rib 102 is formed in the opening of the container main body 101. The outer diameter of the main body rib 102 is larger than the outer diameter of the opening, and the inner diameter is larger than the inner diameter of the opening.

  An inner ring 112 and a side wall 113 are formed on the lid 111. The inner ring 112 and the side wall 113 are formed at positions that sandwich the opening of the container body from the inside and the outside when the lid 111 is closed.

  A lid rib 114 is formed on the inner side surface of the side wall 113. The lid rib 114 has an inner diameter smaller than that of the other part of the inner surface of the side wall 113, and is formed at a position where the main body rib 102 contacts and climbs over when the lid 111 is opened and closed.

  The outer diameter of the inner ring 112 is smaller than the inner diameter of the main body rib 102. Therefore, as shown in FIG. 3, a gap 151 exists between the inner ring 112 and the main body rib 102 in the closed state of the lid 111.

  As for the inner surface of the side wall 113, the inner diameter of the portion on the top surface side of the lid body 111 as viewed from the lid rib 114 is larger than the outer diameter of the main body rib 102. Therefore, as shown in FIG. 3, in the closed state of the lid body 111, a gap 152 exists between this portion of the side wall 113 and the main body rib 102.

  In addition, the lid 111 is formed with a flange 115 on the opposite side of the location where the hinge 121 is connected. The flange portion 115 is formed to be connected to the side wall 113, and the upper surface thereof is connected to the outer top surface of the lid body 111 as an example. The upper surface is inclined, and the thickness of the tip portion of the flange portion 115 is smaller than the thickness of the connection portion with the side wall 113. Moreover, the recessed part 116 is formed in the lower surface side which is a surface facing the upper surface. The closing operation of the lid 111 can be performed by pushing down the upper surface of the collar portion 115 with a finger, and the opening operation can be performed by pushing up the lower surface.

  Hereinafter, how the lid 111 is opened and closed will be described. FIG. 4 is a cross-sectional view of the vicinity of the flange 115 of the container 100 in the process of opening and closing the lid 111.

  When the lid 111 is closed from the open state with the hinge 121 as an axis, first, the main body rib 102 comes into contact with the lid rib 114 as shown in FIG.

  Thereafter, as shown in FIG. 4B, the main body rib 102 is pressed and elastically deformed by the lid rib 114, and the main body rib 102 contacts the lid rib 114 as shown in FIG. 4C. And get over while sliding. Here, getting over means that the main body rib 102 exceeds the top of the lid rib 114 and the return from the deformed state is started.

  As shown in FIG. 4C, after the main body rib 102 gets over the lid rib 114, the inner ring 112 contacts the opening of the container main body 101. Thereafter, as shown in FIG. 4 (d), the inner ring 112 comes into contact with the inner side surface of the opening, is elastically deformed by receiving pressure from the opening, and is fitted while sliding, and the main body rib 102 is elastically deformed. Returns to the closed state.

  When the lid 111 is opened from the closed state with the hinge 121 as an axis, the reverse process described above is followed. That is, from the state shown in FIG. 4D, the inner ring 112 slides on the inner side surface of the opening of the container body 101 and leaves the opening (FIG. 4C), and then the body rib 102 is elastic. The lid rib 114 is overcome while being deformed ((b) of FIG. 4). Further, the main body rib 102 is detached from the lid rib 114 and is in an open state.

  Since the gap 151 exists between the inner ring 112 and the main body rib 102, the main body rib 102 does not contact the inner ring 112 in both the opening operation and the closing operation, and unnecessary interference occurs. Occurrence can be suppressed.

  Further, since the gap 152 exists between the side wall 113 and the main body rib 102, when the main body rib 102 returns from the deformed state when the closing operation is completed, it moves vigorously and within the gap 152 from the original shape. Also, it can be returned to its original shape after being displaced toward the side wall 113. Therefore, when the closing operation is completed, it is possible to obtain a feeling that the lid 111 is closed with a click, and a good sealing feeling is obtained.

  The force required for the opening / closing operation of the lid 111 will be described below. FIGS. 5A and 5B are graphs showing changes over time in the force to be applied to the flange 115 in the closing operation and the closing operation, respectively. The horizontal axis of the graph is time, and the vertical axis is the magnitude of force. This force includes the resistance force X of the main body rib 102 due to friction caused by contact between the main body rib 102 and the lid rib 114 and elastic deformation of the main body rib 102 when getting over, and the opening of the inner ring 112 and the container main body 101. The resultant force X + Y is the resultant force X + Y with the resistance force Y of the inner ring 112 caused by friction due to contact and elastic deformation of the inner ring 112. In FIG. 5, in order to make the graph easier to see, the origin of the vertical axis is shifted in the resultant force graph.

  As shown in FIGS. 5A and 5B, in both the closing operation and the opening operation, the resultant force X + Y has a substantially constant value over a certain period. This is because the period in which the main body rib 102 is in contact with the lid rib 114 and the period in which the inner ring 112 is in contact with the opening of the container main body 101 are shifted, and the period in which each resistance force is generated and its peak are dispersed. is there.

  FIG. 6 shows, for comparison, a graph in the same manner as FIG. 5 when the timing at which each resistance force is generated is changed. In FIG. 6A, the lid 111 when the overlapping period of the period in which the main body rib 102 contacts the lid rib 114 and the period in which the inner ring 112 contacts the opening of the container main body 101 is longer than that of the present embodiment. Each resistance force in the closing operation is shown, and FIG. 6B shows each resistance force in the closing operation in a short case. As shown in FIG. 6A, when the overlapping period is long, the resultant force of each resistance force has a peak, and the force required for the closing operation increases. Further, as shown in FIG. 6B, when the overlapping period is short, when two resultant peaks occur and the first peak has passed, that is, when the main body rib 102 has passed over the lid rib 114. In this case, there is a possibility that the closing operation is completed and the sealing is insufficient. Moreover, since there are two times the peak feel when the lid is closed, a good feeling cannot be obtained compared to the one time peak feeling, and there is a sense of incongruity.

  In FIG. 6C, the lid 111 when the overlapping period of the period in which the main body rib 102 contacts the lid rib 114 and the period in which the inner ring 112 contacts the opening of the container main body 101 is longer than that of the present embodiment. Each resistance force in the opening operation is shown, and FIG. 6D shows each resistance force in the opening operation in a short case. As shown in FIG. 6C, when the overlap period is long, the resultant force of each resistance force has a peak as in the closing operation, and the force required for the opening operation increases. In addition, as shown in FIG. 6D, when the overlap period is short, two resultant peaks are generated as in the closing operation, and the first peak is passed by a short impact force due to a drop or the like. In other words, the inner ring 112 is likely to be detached from the opening of the container body 101, and further, an unintended opening operation may proceed until the minimum value between the peaks, and sealing may be insufficient. is there. Moreover, since there is a peak feel when the lid is opened twice, there is a sense of incongruity compared to a single peak feel.

  The period in which the main body rib 102 contacts the lid rib 114 and the period in which the inner ring 112 contacts the opening of the container main body 101 are the sizes of the main body rib 102, the lid rib 114, the opening of the container main body 101, the gaps 151, 152, etc. It can be adjusted by designing the shape and the like as appropriate. Particularly, by providing the gaps 151 and 152, the adjustment can be suitably performed. In the present embodiment, in the closing operation, after the main body rib 102 comes into contact with the lid rib 114 and gets over the inner ring 112, the inner ring 112 contacts the opening of the container main body 101. In the opening operation, the inner ring 112 is opened. After moving away from the main body rib 102, these periods are adjusted so that the main body rib 102 gets over the lid rib 114, and the peak of each resistance force is shifted as described above so that the resultant force becomes a constant value over a certain period. . As a result, the lid 111 can be opened and closed with a force smaller than the sum of the peak values of the respective resistance forces, and can be easily used for elderly people, women, and children. In addition, an error that stops the closing operation halfway because the resultant force does not have a plurality of peaks (maximum values) or when a good sealing feeling is obtained when the closing operation is completed. In addition, it is possible to reduce unintentional opening operation such as when dropped, and to prevent the sealing from becoming insufficient.

  In addition, since the upper surface of the collar portion 115 is inclined, the correct pushing direction in which the closing operation can be performed with a small force can be guided to the user, so that the user applies a large force in the wrong direction. This can be suppressed. In addition, the concave portion 116 provided on the lower surface of the collar portion 115 causes the collar portion 115 to bend when the collar portion 115 is pushed in. Therefore, the touch can be softened and the push-in portion can be pushed in even if the pushing direction is deviated from the correct direction. Absorbing the force deviation component, it is possible to suppress an excessive force from being applied to the lid rib 114 and the like.

  The main body rib 102 and the lid rib 114 may be provided so as to engage over the entire circumference of the opening of the container main body 101 and the inner side surface of the side wall 113 of the lid body 111, respectively. Or you may provide so that it may engage only in a part among the perimeters. For example, the lid rib 114 may be provided in the vicinity of the flange portion 115, and the outer diameter of the main body rib 102 may be made larger than the outer diameter of the opening of the container main body 101 only in a portion facing the lid rib 114.

  In the closed state, the container body 101 may be sealed by fitting the entire circumference of the tip of the inner ring 112 in contact with the inner surface near the opening of the container body 101 with sufficient contact pressure. Alternatively, the degree of contact and insertion may be low, and sufficient sealing performance may not be required. The gaps 151 and 152 serve as air passages during the closing operation, and even if the container 100 is a sealed type, the increase in the internal pressure of the container 100 is suppressed when the closing operation is completed, so that the repulsive force during sealing is reduced. Can do.

  The container 100 can be integrally molded with a material having a certain rigidity, such as a resin, but the material, size, shape, etc. of the container of the present invention are not particularly limited. Examples of the contents of the container include, but are not limited to, chemicals, test pieces, foods, and the like.

  INDUSTRIAL APPLICABILITY The present invention is useful for a container having a container body and a lid that seals the opening.
