In the urging unit 5, since the urging member 53 is in a state of receiving a load in the direction of closing the second member 52 with respect to the first member 51, the urging member 53 is always second with respect to the first member 51. The member 52 is urged in the opening direction.

Next, a method of attaching the urging unit 5 to the container body 2 will be described. First, as shown in FIG. 7, the urging unit 5 is inserted from the second member 52 side through the opening 21a on the lower side of the first accommodating portion 21. When the urging unit 5 is moved upward, the lower end of the side wall facing the + Y direction of the first accommodating portion 21 comes into contact with the protrusion 51e of the first member 51, and the arm portion 51d of the first member 51 gradually becomes in contact with each other. Rotate inward. When the urging unit 5 is further moved upward, as shown in FIGS. 8 and 11, the entire protrusion 51e is housed in the second through hole 21b of the first housing part 21, and the arm part 51d is moved outward. Rotate. In this state, even if the urging unit 5 is pushed downward, the lower surface of the protrusion 51e engages with the lower surface of the second through hole 21b, and the arm portion 51d cannot rotate, so that the urging unit 5 moves downward. Can't.

In this way, the urging unit 5 is arranged in the second position. In the second position, the first shaft 51a and the second shaft 51b of the first member 51 are accommodated in the first accommodating portion 21. That is, the second axis of the urging unit 5 is accommodated in the first accommodating portion 21.

When the urging unit 5 arranged at the second position is further moved upward, the upper surface of the second through hole 21b and the protrusion 51e come into contact with each other, and the arm portion 51d of the first member 51 gradually moves inward. Rotate. When the urging unit 5 is further moved upward, as shown in FIG. 12, the entire protrusion 51e is accommodated in the first through hole 21c of the first accommodating portion 21, and the arm portion 51d rotates outward. .. Even in this state, even if the urging unit 5 is pushed downward, the lower surface of the protrusion 51e engages with the lower surface of the first through hole 21c, and the arm portion 51d cannot rotate, so that the urging unit 5 moves downward. Can't. At this time, as shown in FIG. 18A, the protrusion 51f extending in the −Y direction from the lower end of the first member 51 of the urging unit 5 engages with the inner wall 21i of the first accommodating portion 21. Therefore, the urging unit 5 cannot move upward any more.

In this way, the urging unit 5 is arranged in the first position. At the first position, the second axis of the urging unit 5 is exposed to the outside. When no force is applied, the second member 52 is opened with respect to the first member 51 by the urging force of the urging member 53.

When the urging unit 5 is arranged at the second position, the urging unit 5 is pulled out from the lower opening 21a when the user pushes the protrusion 51e through the second through hole 21b. There is a risk. Therefore, in the present embodiment, as shown in FIG. 9, by attaching the cover 6 that closes the second through hole 21b to the first accommodating portion 21, the urging unit 5 arranged at the second position can be pulled out. It is preventing.

As shown in FIGS. 10 and 12, the cover 6 has a plate-shaped main body (unsigned) and protrusions 6a at both ends of the main body in the X direction, and a barb 6b is provided at the tip of the protrusion 6a. Has been done. When the protrusion 6a is inserted into the insertion hole 21d after the urging unit 5 is arranged at the second position, the return 6b engages with the inner surface of the first accommodating portion 21, and the cover 6 is fixed. As a result, access to the protrusion 51e through the second through hole 21b is prohibited. At this time, a recess 51c is provided in the portion of the first member 51 facing the protrusion 6a, so that the protrusion 6a can escape and interference between the protrusion 6a and the first member 51 can be prevented.

The first accommodating portion 21 is provided with a protective portion 21e projecting in the + Y direction so as to surround the main body portion of the cover 6. As shown in FIGS. 10 and 11, the protruding height of the protective portion 21e is substantially the same as the thickness of the main body of the cover 6, so that it is difficult to hook a finger or a tool around the main body of the cover 6, and the cover 6 can be easily hooked. Cannot be removed.

Here, when the containers 1 with lids having different sizes are manufactured, the first member 51 and the second member 52 of the urging unit 5 can be used in common, but the size of the lid 3 is large. , It is necessary to use an urging member 53 having an urging force according to the weight. In such a case, the urging force of the urging member 53 can be distinguished by the size of the convex portion provided at the end of the arm 53c. In the urging member 53 having a certain urging force, as shown in FIGS. 4 and 5, the second convex portion 53e in the + X direction is made smaller than the first convex portion 53d in the −X direction, and another In the urging member 53 having an urging force, as shown in FIG. 6, the urging force is distinguished by making the fourth convex portion 53g in the −X direction smaller than the third convex portion 53f in the + X direction. can do. Further, as shown in FIGS. 5 and 6, the first convex portion 53d can be accommodated in the portion of the container body 2 surrounded by the first accommodating portion 21 according to the size of the container 1 with a lid. A groove 21g capable of accommodating the groove 21f or the third convex portion 53f is provided. In addition, in FIGS. 5 and 6, the side wall in the + Y direction of the first accommodating portion 21 is omitted.

As a result, when an urging member 53 having an urging force corresponding to the size of the container 1 with a lid is used, when the urging unit 5 is attached, as shown in FIGS. 5 and 6, the groove 21f is filled with the groove 21f. A third convex portion 53f is housed in the first convex portion 53d and the groove 21g, and each convex portion does not hinder the attachment of the urging unit 5. On the other hand, when an urging member 53 having an urging force that does not correspond to the size of the container 1 with a lid is used, for example, when the urging member shown in FIG. 6 is used for the container body 2 of FIG. 5, the third convex It is possible to notice that the shape portion 53f collides with the lower end of the side wall 21h, the urging unit 5 cannot be attached, and the urging member is erroneous.

(Opening and closing operation)
As the opening / closing operation of the lid body 3, first, the operation from immediately after the lid body 3 is attached to the container body 2 to the closed state will be described.

FIG. 21 is a cross-sectional view from immediately after the lid is attached to the container body to the closed state, and FIG. 21 (a) is a state immediately after the lid is attached to the container body 2 (opening angle 90 °). (B) shows a state in which the opening angle of the lid is 70 °, and FIG. (C) shows a state in which the lid is closed.

Immediately after the lid 3 is attached to the container body 2, as shown in FIG. 21A, the protrusion 23 provided on the container body 2 comes into contact with the barrier 37 provided on the lid 3, and the lid 3 The rotation is hindered. From this state, when a certain force or more is applied in the direction of closing the lid 3, the barrier 37 gradually pushes down the protrusion 23, and as shown in FIG. 21B, the lower end of the barrier 37 gets over the protrusion 23. After that, if a force exceeding the urging force of the urging unit 5 is applied in the direction of closing the lid 3, the lid 3 can be closed as shown in FIG. 21 (c). FIG. 13 shows a state in which the upper part of the container 1 with a lid with the lid 3 closed is viewed from the back.

When the lid 3 is closed, as shown in FIG. 22A, the protrusion 33 provided on the lid 3 is engaged with the engaging member 4 provided on the container body 2, and the lid 3 is closed. Is held in.

When closing the lid 3 in the open state, when the lid 3 is pushed down, the upper end of the engaging member 4 comes into contact with the vertical plate 33b of the protrusion 33, and when the lid 3 is further pushed down, the vertical plate 33b of the protrusion 33 makes contact. The side wall 4b of the engaging member 4 rotates in the −Y direction. When the lid 3 is completely closed, the protrusion 33 is fitted into the lateral groove 4c and the vertical groove 4d of the engaging member 4, the engaging member 4 is urged by the urging member 4a, and the side wall 4b rotates in the + Y direction. .. In this state, even if the lid 3 is urged in the opening direction by the urging unit 5, the lid 3 does not open because the protrusion 33 and the engaging member 4 are engaged.

When the engaging member 4 is pushed down with the lid 3 closed, the side wall 4b rotates in the −Y direction as shown in FIG. 22 (b), the engagement with the protrusion 33 is released, and the urging member 4 is urged. The urging force of the unit 5 makes it possible to rotate the lid 3 in the opening direction. When the lid 3 in the closed state is opened only by the urging force of the urging unit 5, the lower end of the barrier 37 cannot get over the protrusion, so that the lid 3 rotates at the opening angle shown in FIG. 21 (b). Stops.

(Action of packing)
Next, the action of the packing in the container with a lid of the present embodiment will be described.

When the lid 3 is closed with respect to the container body 2, the container body 2 and the lid 3 are held by the engaging mechanism with the packing 7 sandwiched between the protrusion 24 and the groove 32a. At this time, the deformed portion 7b of the packing 7 is deformed and comes into close contact with the protruding portion 24, and the space between the container body 2 and the lid 3 is sealed.

In the present embodiment, the deformed portion 7b of the packing 7 is supported from the outside by the outer wall 32b and is opened to the inside in the width direction of the groove portion 32a. Therefore, when the packing 7 is sandwiched between the groove portion 32a and the protrusion portion 24, the deformation direction of the deformed portion 7b is limited to the inside. As a result, as compared with the case where the deformation direction of the deformed portion 7b varies inward and outward, it is difficult to form a portion that is difficult to adhere between the protrusion 24 and the packing 7, and the space between the container body 2 and the lid 3 is stable. Can be sealed. Further, since the deformed portion 7b is provided on the outside of the groove portion 32a, it is easy to pinch and the packing 7 can be easily removed from the groove portion 32a. In addition, the outer wall 32b makes it possible to prevent the contained matter and its odor from leaking out of the container.

In the present embodiment, the deformed portion 7b is hollow and more easily deformed than when it is solid, so that it is possible to make it more difficult for a portion that is difficult to adhere between the protrusion 24 and the packing 7 to occur.

Further, when the deformed portion 7b is sandwiched between the protruding portions 24, the deformed portion 7b rotates around the outer portion of the deformed portion 7b supported by the outer wall 32b as a central axis. In the present embodiment, the outer wall of the deformed portion 7b is thicker than the bottom plate 7c, the inner wall 7d, and the stretched portion 7e, and is less likely to be deformed than these portions, so that the central axis of rotation of the deformed portion 7b is less likely to shake. Further, in the present embodiment, as shown in FIG. 21 (c) and the like, the protrusion 24 sandwiches the deformed portion inside the center of the deformed portion 7b in the width direction, and the deformed portion 7b is formed in the groove portion 32a. It has a width wider than the width. Therefore, the radius of rotation of the deformed portion 7b is larger than when the deformed portion 7b is sandwiched outside the center of the deformed portion 7b in the width direction and when the width of the deformed portion 7b is equal to or less than the width of the groove portion 32a. Further, the portion sandwiched between the protrusions 24 is closer to the end of the deformation portion 7b in the deformation direction (inward direction). From these facts, the deformed portion 7b can be deformed even with a smaller force than when the deformed portion 7b is sandwiched outside the center of the deformed portion 7b in the width direction, and the container body and the lid can be more stably connected to each other. The space can be sealed.

In the present embodiment, the accommodating portion 7a of the packing 7 is hollow, but since the reinforcing portion 7f is provided inside the accommodating portion 7a, it is difficult to be crushed inside the groove portion 32a. Further, the accommodating portion 7a may be solid. If the housed portion 7a is solid, the rigidity is higher than when it is hollow, so that the housed portion 7a can be easily housed in the groove portion 32a.

In the present embodiment, a tapered portion 7g is formed at the end of the accommodating portion 7a opposite to the deformed portion 7b, and the accommodating portion 7a can be more easily accommodated in the groove portion 32a.
