Embodiments for Carrying Out the Invention

[0012] Hereinafter, an embodiment of a lid-equipped container according to the present invention will be described with reference to the drawings. In the following description, the vertical direction is the direction along the axis O shown in the drawings. The radial direction is a direction orthogonal to the axis O in a plane perpendicular to the axis O, and the circumferential direction is a direction that circulates around the axis O in this plane.

[0013] As shown in Fig. 1, the covered container 1 of the present embodiment is composed of an outer container 2 (composed of an outer container body 3 and a screw member 4), an inner container 5, a tray body 6, and a lid body 7 (composed of an inner lid body 8, an outer lid body 9, and a packing 10). As shown in the figure, these members are all formed in a shape centered on the axis O. In Fig. 1, the figure shown on the right side with the axis O as the boundary shows the state where the tray body 6 is located below, and the figure shown on the left side shows the state where the tray body 6 is located above.

[0014] The outer container body 3 includes a disk-shaped bottom wall portion 3a extending in the horizontal direction and a cylindrical inner peripheral wall 3b extending upward from the outer edge portion of the bottom wall portion 3a. On the upper surface of the central portion of the bottom wall portion 3a, a cylindrical tubular wall 3c rising upward is provided. On the outer peripheral surface of the tubular wall 3c, outward vertical ribs 3d extending along the vertical direction are provided. A plurality of outward vertical ribs 3d are provided at intervals in the circumferential direction with respect to the outer peripheral surface of the tubular wall 3c (see Fig. 2(b)). And at the upper end portion of the inner peripheral wall 3b, a claw-shaped portion 3e protruding radially outward and having a claw shape is provided.

[0015] An outer peripheral wall 3f having a stepped cylindrical shape is provided on the radially outer side of the inner peripheral wall 3b. On the upper portion of the outer peripheral wall 3f, a mounting screw portion 3g having a male screw shape is provided. The mounting screw portion 3g is screwed with a mounting female screw portion 8c provided on the lid body 7 described later. The mounting screw portion 3g and the mounting female screw portion 8c in the present embodiment are right-handed screws. When the lid body 7 is rotated clockwise (tightening direction) in a plan view with respect to the outer container body 3 as shown in Fig. 2, the mounting female screw portion 8c is tightened with respect to the mounting screw portion 3g, and when rotated counterclockwise (loosening direction), the mounting female screw portion 8c is loosened with respect to the mounting screw portion 3g.

[0016] The screw member 4 has a lid-shaped cylindrical form and includes a base portion 4a that is inserted into the cylindrical wall 3c. On the inner peripheral surface of the base portion 4a, inward vertical ribs 4b extending along the vertical direction are provided. A plurality of the inward vertical ribs 4b are provided at intervals in the circumferential direction with respect to the inner peripheral surface of the base portion 4a. The inward vertical ribs 4b engage with the outward vertical ribs 3d when the base portion 4a is inserted into the cylindrical wall 3c (see Fig. 2(b)). That is, the screw member 4 is held by the cylindrical wall 3c, the base portion 4a, etc. so as not to be rotatable about the axis O and to be detachable in the vertical direction with respect to the outer container body 3. On the outer peripheral surface of the base portion 4a, a male-threaded upward screw portion 4c is provided.

[0017] On the outer peripheral surface of the base portion 4a, a lower wall 4d is provided that extends downward while curving toward the radially outer side and then extends in the horizontal direction. At the outer edge portion of the lower wall 4d, protrusions (second engaged portions 4e) protruding toward the radially outer side as shown in Fig. 2(b) are provided. A plurality of the second engaged portions 4e are provided at intervals in the circumferential direction.

[0018] The inner container 5 is located above the lower wall 4d and has an intermediate wall 5a having a space therebetween and the lower wall 4d. The intermediate wall 5a is formed in a shape that extends downward while curving radially outward from a portion located radially outside the base portion 4a and then extends horizontally. As shown in FIG. 2(b), a recess 5b is provided at the inner edge portion (the portion located radially outside the base portion 4a) of the intermediate wall 5a. The recess 5b of the present embodiment is rectangular in plan view and a plurality of (six in the present embodiment) are provided at intervals in the circumferential direction. Further, at the outer edge portion of the intermediate wall 5a, there is provided a claw-shaped portion (second engaging portion 5c) having one end connected to the outer edge portion of the intermediate wall 5a and being elastically deformable in the radial direction, and the other end formed to project radially inward. As shown in FIG. 2(b), a total of three second engaging portions 5c of the present embodiment are provided at intervals in the circumferential direction. Further, as shown in FIG. 2(b), when the inner container 5 rotates in the loosening direction with respect to the screw member 4, the second engaging portion 5c engages with the second engaged portion 4e, and when the inner container 5 rotates in the tightening direction with respect to the screw member 4, it elastically deforms radially outward when approaching the second engaged portion 4e to overcome the second engaged portion 4e and idles with respect to the second engaged portion 4e.

[0019] Further, the inner container 5 is connected to the intermediate wall 5a and, as shown in FIG. 1, extends upward along the inner peripheral surface of the inner peripheral wall 3b and then extends radially outward so as to cover the upper end portion of the inner peripheral wall 3b, and then includes a peripheral wall portion 5e that extends downward along the outer peripheral surface of the inner peripheral wall 3b. A portion of the peripheral wall portion 5e that extends downward along the outer peripheral surface of the inner peripheral wall 3b is engaged with the claw-shaped portion 3e, whereby the inner container 5 is rotatably held with respect to the outer container body 3.

[0020] The peripheral wall portion 5e includes a protrusion (first engaging portion 5f) that projects radially outward as shown in FIG. 2(a) on the outer peripheral surface at a portion that extends downward along the outer peripheral surface of the inner peripheral wall 3b. A plurality of first engaging portions 5f are provided at intervals in the circumferential direction.

[0021] As shown in Fig. 1, the tray body 6 is provided with a tray portion 6a located above the intermediate wall 5a. The tray portion 6a of the present embodiment extends horizontally radially outward from the axis O and then extends in an arc shape downward. And at the outer edge portion of the tray portion 6a, there are provided contact portions 6b that extend upward and downward respectively, can be elastically deformed radially inward, and contact the inner peripheral surface of the peripheral wall portion 5e. As will be described later, the tray portion 6a can move upward, and at this time, the contact portion 6b slides with respect to the peripheral wall portion 5e while being in contact with the inner peripheral surface of the peripheral wall portion 5e. Here, the space surrounded by the tray portion 6a, the contact portion 6b, and the peripheral wall portion 5e is referred to as the content accommodation space S. For example, gel-like or cream-like contents are accommodated in the content accommodation space S.

[0022] As shown in Fig. 3, strip-shaped flexible pieces 6c that extend downward are provided on the lower surface of the tray portion 6a. The flexible pieces 6c can be elastically deformed radially outward. In the present embodiment, a plurality (six in the present embodiment) of the flexible pieces 6c are provided at intervals in the circumferential direction around the axis O. As shown in Figs. 1 and 2(b), the flexible pieces 6c can be inserted into the recesses 5b. When the flexible pieces 6c are inserted into the recesses 5b, the flexible pieces 6c are positioned in the circumferential direction by the recesses 5b, so that the tray body 6 is rotationally locked and held with respect to the inner container 5. Also, when the tray portion 6a is positioned downward as shown in the figure on the right side with the axis O in Fig. 1 as the boundary, the flexible pieces 6c are elastically deformed radially outward and are housed in the space partitioned between the lower wall 4d and the intermediate wall 5a. That is, since the height of the space located between the lower wall 4d and the intermediate wall 5a is suppressed by the elastic deformation of the flexible pieces 6c, the vertical size of the container 1 with a lid can be reduced. And on the inner peripheral surface of the flexible pieces 6c, there are provided female threaded portions 6d for rising that are located at the central portion in the width direction of the flexible pieces 6c and are formed in a female threaded shape so as to be screwed with the male threaded rising screw portions 4c. The rising screw portions 4c and the female threaded portions 6d for rising are configured such that when the female threaded portions 6d for rising rotate in the tightening direction shown in Fig. 2 with respect to the rising screw portions 4c, the female threaded portions 6d for rising are sent upward with respect to the rising screw portions 4c.

[0023] The inner lid body 8 includes a disk-shaped top wall 8a extending in the horizontal direction. An inner peripheral wall 8b extending downward is provided at the outer edge portion of the top wall 8a. And on the inner peripheral surface of the inner peripheral wall 8b, a female screw-shaped mounting female screw portion 8c that engages with the above-described mounting screw portion 3g is provided. Further, on the outer peripheral surface of the inner peripheral wall 8b, outward vertical ribs 8d extending along the vertical direction are provided. A plurality of the outward vertical ribs 8d are provided at intervals in the circumferential direction with respect to the outer peripheral surface of the inner peripheral wall 8b.

[0024] Also, above the mounting female screw portion 8c of the inner lid body 8, as shown in Fig. 2(a), one end is connected to the inner peripheral wall 8b and is elastically deformable in the radial direction, and the other end is formed to project inward in the radial direction. It is provided with a claw-shaped portion (first engaged portion 8e). As shown in Fig. 2(a), a total of two first engaged portions 8e of the present embodiment are provided at intervals in the circumferential direction. Further, as shown in Fig. 2(a), when the inner lid body 8 rotates in the tightening direction with respect to the inner container 5, the first engaged portion 8e engages with the first engaging portion 5f. When the inner lid body 8 rotates in the loosening direction with respect to the inner container 5, when it comes into contact with the first engaging portion 5f, it elastically deforms outward in the radial direction and gets over the first engaging portion 5f, and idles with respect to the first engaging portion 5f.

[0025] The outer lid body 9 includes a disk-shaped top wall 9a extending in the horizontal direction above the top wall 8a. An outer peripheral wall 9b surrounding the inner peripheral wall 8b and extending downward is provided at the outer edge portion of the top wall 9a. On the inner peripheral surface of the outer peripheral wall 9b, inward vertical ribs 9c extending along the vertical direction are provided. A plurality of the inward vertical ribs 9c are provided at intervals in the circumferential direction with respect to the inner peripheral surface of the base portion 4a. The inward vertical ribs 9c engage with the outward vertical ribs 8d when the inner lid body 8 is inserted inside the outer lid body 9. Thereby, the inner lid body 8 is rotationally locked and held by the outer lid body 9. Further, below the inward vertical ribs 9c on the inner peripheral surface of the outer peripheral wall 9b, an engaging convex portion 9d projecting inward in the radial direction is provided. The engaging convex portion 9d engages with the lower end portion of the inner peripheral wall 8b when the inner lid body 8 is inserted inside the outer lid body 9. Thereby, the inner lid body 8 is retained against coming off by the outer lid body 9.

[0026] The packing 10 is formed in a disc shape from an elastic material and is provided on the lower surface of the top wall 8a. When the lid body 7 is rotated to the end in the tightening direction with respect to the outer container 2, the packing 10 is sandwiched between the upper end surface of the peripheral wall portion 5e and the lower surface of the top wall 8a, and closes the content accommodation space S.

[0027] When taking out the content from the container 1 with a lid having such a configuration, the lid body 7 is rotated with respect to the outer container 2 in the loosening direction shown in FIG. 2. That is, with one hand holding the outer container body 3 and the other hand grasping the outer lid body 9, the outer lid body 9 is rotated in the loosening direction. As described above, the outer lid body 9 holds the inner lid body 8 in a non-rotating state. Further, as shown in FIG. 2(a), when the inner lid body 8 rotates in the loosening direction, the first engaged portion 8e idles with respect to the first engaging portion 5f, so the inner container 5 does not rotate, and the outer lid body 9 and the inner lid body 8 rotate in the loosening direction. Then, when the screwing between the mounting screw portion 3g and the mounted screw portion 8c is released, the lid body 7 can be removed with respect to the outer container 2, so that the content accommodated in the content accommodation space S can be taken out with a hand, a spatula, or the like.

[0028] In a state where the lid body 7 is fastened to the outer container 2, the packing 10 is sandwiched between the upper end surface of the peripheral wall portion 5e and the lower surface of the top wall 8a. For this reason, when the outer lid body 9 is rotated in the loosening direction, even though the first engaged portion 8e idles with respect to the first engaging portion 5f, a rotational force in the loosening direction may be transmitted from the packing 10 to the peripheral wall portion 5e (that is, to the inner container 5). In contrast, in the present embodiment, as shown in FIG. 2(b), a second engaged portion 4e is provided on the screw member 4, and a second engaging portion 5c is provided on the inner container 5. Further, as described above, the screw member 4 is rotationally held by the outer container body 3. Therefore, when the outer lid body 9 is rotated in the loosening direction, even if a rotational force in the loosening direction is transmitted to the inner container 5, the second engaging portion 5c engages with the second engaged portion 4e and the inner container 5 is rotationally held by the outer container body 3, so that the inner container 5 does not rotate. Here, the tray body 6 is rotationally held by the inner container 5 as described above, and the screw portion 6d for raising provided on the tray body 6 as shown in FIG. 1 is screwed into the screw portion 4c for raising provided on the screw member 4. That is, even when the outer lid body 9 is rotated in the loosening direction, since the inner container 5 and the tray body 6 do not rotate, the screw portion 6d for raising does not rotate with respect to the screw portion 4c for raising, and the tray body 6 is maintained in its height state.

[0029] On the one hand, when the lid 7 is rotated with respect to the outer container 2 in the tightening direction shown in FIG. 2, the inner lid 8 rotates in the tightening direction together with the outer lid 9. In this state, as shown in FIG. 2(a), since the first engaged portion 8e engages with the first engaging portion 5f, the inner container 5 also rotates in the tightening direction together with the inner lid 8. And the saucer body 6 that is rotationally locked to the inner container 5 also rotates in the tightening direction. As described above, the screw portion 4c for lifting and the screw portion 6d to be screwed for lifting are configured such that when rotated in this direction, the screw portion 6d to be screwed for lifting is sent upward with respect to the screw portion 4c for lifting. Therefore, when the screw portion 6d to be screwed for lifting is sent upward, the saucer body 6 rises with respect to the inner container 5. Note that the rotation amount of the lid 7 with respect to the outer container 2 and the rising amount of the saucer body 6 with respect to the inner container 5 can be appropriately changed, for example, by adjusting the pitch of the screw portion 4c for lifting and the screw portion 6d to be screwed for lifting. In the present embodiment, it is set such that when the lid 7 is rotated about 20° to 30° with respect to the outer container 2, the saucer body 6 rises about 0.2 mm with respect to the inner container 5.

[0030] Note that when the lid 7 is rotated in the tightening direction with respect to the outer container 2, as shown in FIG. 2(b), since the second engaging portion 5c idles with respect to the second engaged portion 4e, the rotation of the inner container 5 in the tightening direction is not inhibited.

[0031] When the lid 7 is rotated in the tightening direction with respect to the outer container 2 in this way, the saucer body 6 gradually rises with respect to the inner container 5 (see the figure shown on the left side with the axis O in FIG. 1 as the boundary). That is, after taking out the contents stored in the content storage space S, the saucer body 6 rises every time the lid 7 is attached to the outer container 2. Therefore, even when the contents are reduced, it is not necessary to deeply insert a finger, a spatula, or the like into the inner container 5, and the contents can be easily taken out.

[0032] Also, the screw member 4 of the present embodiment is detachably held in the vertical direction with respect to the outer container body 3. Therefore, when the contained content decreases, as shown in FIG. 4, the inner container 5 that has been used is removed from the outer container body 3 (as shown in the figure, the screw member 4 and the saucer body 6 can also be removed together with the inner container 5), and a new inner container 5 can be attached to the outer container 2. That is, according to the covered container 1 of the present embodiment, even when the content decreases and a new inner container 5 is used, the outer container body 3 can be reused.

[0033] As described above, one embodiment of the present invention has been described. However, the present invention is not limited to such a specific embodiment, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims, unless otherwise particularly limited in the above description. Also, the effects in the above embodiment are merely examples of the effects resulting from the present invention, and it does not mean that the effects of the present invention are limited to the above effects.

[0034] For example, in the present embodiment, the outer container 2 is composed of the outer container body 3 and the screw member 4, so that the inner container 5 can be replaced. However, when this function is omitted, the outer container body 3 and the screw member 4 may be integrally configured. Also, the lid body 7 is not limited to being composed of the inner lid body 8 and the outer lid body 9, and a member in which the inner lid body 8 and the outer lid body 9 are integrally joined may be used.
