DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] Hereinafter, a cap and a container including the cap, which are exemplary embodiments of the present invention, will be described with reference to the drawings. However, in the following description, in order to simplify the description, the meanings of terms are defined as follows.

[0013] "Axial direction" refers to the direction in which the axis O of the cap (hereinafter simply referred to as "axis O") extends. The axis of the container is coaxial with the axis O of the cap. Furthermore, for a cap, "top" or "upper side" refers to the side on which the lid is located in the axial direction, and "bottom" or "lower side" refers to the side on which the cap body is located in the axial direction. For a container, the side on which the lid of the cap is located is referred to as "top" or "upper side," and the side on which the bottom of the container body is located is referred to as "bottom" or "lower side."

[0014] Next, the "radial direction" refers to a direction perpendicular to the axial direction. Furthermore, the "radial inner side" refers to the side closer to the axis O, and the "radial outer side" refers to the side farther from the axis O. Furthermore, the "circumferential direction" refers to the circumferential direction around the axis O.

[0015] FIG. 1 shows a schematic diagram of a container 10A according to a first embodiment of the present invention.

[0016] The container 10A includes a container body 4 having a mouth portion 4a and in which a storage space S1 for storing contents is formed, and a cap (container cap) 1A according to the first embodiment of the present invention.

[0017] In this embodiment, the container body 4 is a bottle container extending in the axial direction. In this embodiment, the container body 4 includes, along the axial direction, a mouth portion 4a, a neck portion 4b connected to the mouth portion 4a, a shoulder portion 4c connected to the neck portion 4b, a body portion 4d connected to the shoulder portion 4c, and a bottom portion 4e connected to the body portion 4d. In this embodiment, the lower end of the body portion 4d is closed by the bottom portion 4e. Inside the container body 4, a storage space S1 is formed to store a liquid as the content. The storage space S1 is connected to the outside world through an opening A1 formed at the upper end of the mouth portion 4a. The container body 4 can be, for example, a blow-molded product made of a synthetic resin.

[0018] The cap 1A includes a cap body 2 that closes an opening 4a of a container body 4, and a lid body 3 that covers the cap body 2 in a detachable manner.

[0019] The cap body 2 comprises a lower mounting tube 21 attached to the outer peripheral surface of the mouth 4a of the container body 4, a partition wall 22 that is continuous with the inner peripheral surface of the lower mounting tube 21 and closes the mouth 4a of the container body 4, and an upper mounting tube 23 that extends from the partition wall 22 toward the upper side (lid body 3) and is removably attached to the inner peripheral surface of the lid body 3 by screws.

[0020] In this embodiment, the cap body 2 has an annular protrusion 21p on the inner peripheral surface of the lower end of the lower mounting tube 21. Also, in this embodiment, the container body 4 has an annular protrusion 4p on the outer peripheral surface of the mouth portion 4a. In this embodiment, the cap body 2 is attached to the container body 4 by fitting the annular protrusion 21p into the annular protrusion 4p formed on the mouth portion 4a of the container body 4.

[0021] Additionally, in this embodiment, the cap body 2 includes a sealing tube 27 extending from the annular portion 22b of the partition wall 22 toward the container body 4. As shown in Fig. 1, when the cap body 2 is attached to the container body 4, the sealing tube 27 comes into contact with the inner circumferential surface of the mouth portion 4a of the container body 4, thereby sealing the opening A1 formed at the upper end of the mouth portion 4a of the container body 4.

[0022] The partition wall 22 comprises a bulge portion (hereinafter also referred to as the "partition wall bulge portion") 22a that bulges upward, an annular portion (hereinafter also referred to as the "partition wall annular portion") 22b that circumferentially surrounds the partition wall bulge portion 22a, a ring-shaped portion to be cut 22c that separably separates the partition wall bulge portion 22a and the partition wall annular portion 22b, an extension tube 24 that extends downward from the partition wall annular portion 22b so as to surround the portion to be cut 22c, and a plurality of shelf portions 25 that are spaced apart circumferentially of the extension tube 24 and extend radially inward from the lower end of the extension tube 24.

[0023] In this embodiment, the partition wall bulge 22a bulges upward about the axis O. In this embodiment, the partition wall bulge 22a is formed in two stages, upper and lower, with a large diameter portion 22a1 arranged on the lower side and a small diameter portion 22a2 arranged above the large diameter portion 22a1. The small diameter portion 22a2 is continuous with the large diameter portion 22a1 and has a smaller diameter than the large diameter portion 22a1. As shown in FIG. 1, the upper end of the small diameter portion 22a2 is closed.

[0024] The partition wall bulge 22a and the partition wall annular portion 22b are connected separably by the portion to be cut 22c. In this embodiment, the portion to be cut 22c is connected to the outer peripheral surface of the lower end of the partition wall bulge 22a (the outer peripheral surface of the lower end of the large diameter portion 22a1) and the radially inner end of the partition wall annular portion 22b. The lower mounting tube 21 connected to the radially outer edge of the partition wall annular portion 22b is fixed to the mouth portion 4a of the container body 4. Therefore, if the partition wall bulge 22a is pulled upward while being twisted by engaging with the retaining tube 32 of the lid body 3 as described later, the portion to be cut 22c is cut, and the partition wall bulge 22a can be separated from the partition wall annular portion 22b. As a result, an opening (through hole) A2 whose outer shape is shaped by the portion to be cut 22c is formed in the partition wall 22 of the cap body 2. In this embodiment, the portion to be cut 22c is a cuttable thin-walled portion that extends annularly in the circumferential direction around the axis O.

[0025] In this embodiment, the shelf portions 25 are arranged at intervals in the circumferential direction at the lower end of the extension tube 24 connected to the partition wall annular portion 22b, and function as a movable cage supported at one end by the extension tube 24.

[0026] In this embodiment, the base 25a of the shelf 25 connected to the extension tube 24 is formed by a hinge that can bend the shelf 25 radially inward. In this embodiment, the base 25a of the shelf 25 is formed by a thin-walled portion that is connected to the outer circumferential surface of the lower end of the extension tube 24. This allows the shelf 25 to be easily bent radially inward with the base 25a of the shelf 25 as a base point, as shown in FIG.

[0027] In this embodiment, the shelf 25 includes a bent portion 25d that is continuous with the base 25a. In this embodiment, the shelf 25 also includes a shelf body 25f that is continuous with the bent portion 25d. In this embodiment, the shelf body 25f is plate-shaped. In this embodiment, a solid object C2 can be placed on the upper surface of the shelf body 25f. The bent portion 25d is bent radially inward so that the shelf body 25f is disposed substantially horizontally at a position lower than the base 25a.

[0028] In addition, in this embodiment, the cap body 2 includes a stopper (26a) that contacts the shelf portion 25 when the shelf portion 25 is bent upward from the base portion 25a, thereby limiting the bending of the shelf portion 25. In this embodiment, the stopper (26a) is the lower end 26a of the rib 26 provided on the inner peripheral surface of the extension tube 24. In this embodiment, the rib 26 extends in the axial direction as shown in FIG. 1. As shown in FIG. 1, in this embodiment, the lower end 26a of the rib 26 is located lower than the lower end of the extension tube 24. As a result, in this embodiment, the lower end 26a of the rib 26 functions as a stopper that contacts the shelf portion 25 when the shelf portion 25 is bent toward the lid body 3 from the base portion 25a, thereby limiting the bending of the shelf portion 25. In this embodiment, the stopper (26a) contacts the upper end of the bent portion 25d of the shelf portion 25, thereby limiting the bending of the shelf portion 25.

[0029] 1, the lid 3 includes a top wall 31 disposed above the cap body 2, and a retaining tube 32 extending downward from the top wall 31 and retaining the partition wall bulge 22a of the cap body 2 to prevent it from coming off. The lid 3 can be manufactured by injection molding using a mold, using a synthetic resin as a raw material. Between the upper mounting tube 23 of the cap body 2 and the retaining tube 32 of the lid 3, a storage space S2 is formed, which is closed by the partition wall 22 of the cap body 2 and the top wall 31 of the lid 3, and which is for storing at least one solid object C2.

[0030] In this embodiment, the lid body 3 includes a mounting tube 33 that is removably attached to the outer circumferential surface of the upper mounting tube 23 of the cap body 2 by a screw. The mounting tube 33 extends from the top wall 31 toward the cap body 2 so as to surround the upper mounting tube 23 of the cap body 2. In this embodiment, a female thread 33s is formed on the inner circumferential surface of the mounting tube 33. Meanwhile, a male thread 23s is formed on the outer circumferential surface of the upper mounting tube 23 of the cap body 2. The male thread 23s can be screwed into the female thread 33s. This allows the lid body 3 to be removably attached to the cap body 2 by a screw. In this embodiment, the male thread 23s and the female thread 33s are multiple threads. That is, in this embodiment, the lid body 3 is removably attached to the outer circumferential surface of the upper mounting tube 23 of the cap body 2 by a multiple thread.

[0031] Additionally, in this embodiment, the lid 3 includes a sealing tube 37 extending downward from the top wall 31. As shown in Fig. 1, when the lid 3 is attached to the cap body 2, the sealing tube 37 comes into contact with the inner peripheral surface of the upper mounting tube 23 of the cap body 2 to seal the opening A3 formed at the upper end of the upper mounting tube 23.

[0032] The retaining tube 32 of the lid body 3 extends downward from the top wall 31. In this embodiment, the retaining tube 32 is provided so as to surround the partition wall bulge 22a when the lid body 3 is attached to the cap body 2. In this embodiment, the lid body 3 is provided with an annular protrusion 32p on the inner peripheral surface of the lower end of the retaining tube 32. In contrast, in this embodiment, the cap body 2 is provided with an annular protrusion 22p on the outer peripheral surface of the partition wall bulge 22a. In this embodiment, the cap body 2 is provided with an annular protrusion 22p on the outer peripheral surface of the large diameter portion 22a1 of the partition wall bulge 22a. In this embodiment, the partition wall bulge 22a of the cap body 2 is fitted into the annular protrusion 32p formed on the retaining tube 32 of the lid body 3, so that it is retained by the retaining tube 32 of the lid body 3 and does not come off. As a result, when the lid body 3 is pulled upward, the partition wall bulge portion 22a of the cap body 2 is pulled upward following the pulling up of the lid body 3. As a result, the portion to be cut 22c provided on the partition wall 22 of the cap body 2 can be cut.

[0033] In this embodiment, the radial outer side of the partition wall annular portion 22b of the cap body 2 is partitioned in a ring shape in the circumferential direction around the axis O by the upper mounting tube 23. On the other hand, the radial inner side of the partition wall annular portion 22b of the cap body 2 is partitioned in a ring shape in the circumferential direction around the axis O by the retaining tube 32 of the lid body 3. Furthermore, the upper side of the partition wall annular portion 22b of the cap body 2 is closed by the top wall 31 of the lid body 3. As a result, in this embodiment, an annular storage space S2 is formed between the cap body 2 and the lid body 3, in which the partition wall annular portion 22b of the cap body 2 serves as a bottom, the retaining tube 32 of the lid body 3 functions as an inner peripheral wall, the upper mounting tube 23 of the cap body 2 functions as an outer peripheral wall, and the top wall 31 of the lid body 3 functions as a top wall. As shown in FIG. 1, at least one solid object C2 can be stored in this storage space S2.

[0034] Furthermore, the bulge portion 22a provided on the partition wall 22 of the cap body 2 and the retaining tube 32 of the lid body 3 are provided with an engagement portion WS that engages the bulge portion 22a with the retaining tube 32 of the lid body 3 to cut the portion to be cut 22c when the lid body 3 is twisted in the direction of removing it from the cap body 2.

[0035] In this embodiment, the engagement portion WS is configured by a ratchet mechanism. The ratchet mechanism includes ratchet teeth 28 and a ratchet pawl 38. The ratchet mechanism allows the lid body 3 to rotate around the axis O relative to the cap body 2 in one circumferential direction, while preventing the lid body 3 from rotating in the other circumferential direction.

[0036] 2 shows the cap 1 in a cross section taken along the line XX in FIG. 1. In FIG. 2, the cap 1 is shown from above. As shown in FIG. 2, a plurality of ratchet teeth 28 are provided at intervals in the circumferential direction on the outer peripheral surface of the partition wall bulging portion 22a of the cap body 2. In detail, in this embodiment, the ratchet teeth 28 are provided on the outer peripheral surface of the small diameter portion 22a2 of the partition wall bulging portion 22a. Meanwhile, as shown in FIG. 2, a plurality of ratchet pawls 38 are provided at intervals in the circumferential direction on the inner peripheral surface of the retaining tube 32 of the lid body 3.

[0037] 2, in this embodiment, when the lid body 3 is attached to the cap body 2 by a screw, the retaining cylinder 32 of the lid body 3 rotates rightward (clockwise) around the axis O. In this case, the ratchet pawl 38 rides over the ratchet teeth 28, thereby allowing the lid body 3 to rotate freely relative to the cap body 2. This allows the lid body 3 to be attached to the cap body 2 by the screw.

[0038] In contrast, in this embodiment, when the lid body 3 is removed from the cap body 2, the retaining tube 32 of the lid body 3 rotates leftward (counterclockwise) around the axis O. In this case, the ratchet pawl 38 engages with the ratchet teeth 28, thereby allowing the partition wall bulge 22a of the cap body 2 to rotate together with the retaining tube 32 of the lid body 3. This allows the partition wall bulge 22a of the cap body 2 to be twisted in the circumferential direction relative to the partition wall annular portion 22b while the lid body 3 is being removed from the cap body 2. This twisting allows the partition wall bulge 22a of the cap body 2 to be separated from the partition wall annular portion 22b by cutting the cut portion 22c, while removing the lid body 3. The partition wall bulge 22a separated from the partition wall annular portion 22b is transferred to the lid body 3 by being held by the retaining tube 32 of the lid body 3 so as not to come off.

[0039] In FIG. 3, the shelf portion 25 of the cap 1A is shown generally from below together with the extension tube 24.

[0040] In this embodiment, the shelf portion 25 is formed in a sector shape tapered toward the axis O in a plan view as shown in FIG. 3. In this embodiment, the shelf portion 25 is arranged at four positions at intervals in the circumferential direction around the axis O. Between each of the four shelf portions 25, a cross-shaped gap G is formed as shown in FIG. 3. The gap G allows the contents contained in the container body 4 to flow. In this embodiment, the tip 25b of the shelf portion 25 is formed in an arc shape recessed toward the radially outward direction as shown in FIG. 3. However, it is sufficient that there are at least two or more shelf portions 25. In addition, the circumferential gap between the shelf portions 25 adjacent to each other in the circumferential direction can be appropriately adjusted depending on the size of the solid C2, the contents C1 contained in the container body 4, etc.

[0041] Next, an example of how to use the container 10A in Fig. 1 will be described. Here, the content C1 of the container body 4 is a liquid content related to health food (e.g., a lactic acid bacteria drink). Also, the solid C2 contained in the cap 1A is a tablet that activates the liquid content (e.g., a tablet that proliferates intestinal bacteria such as lactic acid bacteria).

[0042] As shown in Fig. 1, container 10A accommodates contents C1 in accommodation space S1 formed inside container body 4, and accommodates solid matter C2 in accommodation space S2 formed in cap 1A. When not in use, as shown in Fig. 1, accommodation space S1 and accommodation space S2 are separated by partition wall 22 of cap body 2. Therefore, content C1 and solid matter C2 do not come into contact with each other when container 10A is not in use.

[0043] When using the container 10A, the lid 3 is rotated in the direction in which the screw is removed.

[0044] 4 shows the lid body 3 in a state where it has been removed from the cap body 2. As shown in FIG. 4, when the lid body 3 is removed from the cap body 2, the partition wall bulge portion 22a of the cap body 2 is separated from the partition wall annular portion 22b together with the lid body 3. As a result, an opening A2 is formed in the cap body 2, which is formed by the radial inner edge (portion to be cut 22c) of the partition wall annular portion 22b. The opening A2 communicates the storage space S1 formed in the container body 4 with the outside world via the gap G.

[0045] On the other hand, the storage space S2 formed in the cap body 2 is expanded to the entire inside of the upper mounting tube 23 of the cap body 2 by removing the lid body 3, as shown in FIG. 4. At this time, the solid object C2 stored in the cap body 2 may fall into the inside of the extension tube 24. In contrast, according to this embodiment, as shown by the two-dot chain line in FIG. 1, the solid object C2 that has fallen into the inside of the extension tube 24 is placed on the shelf body 25f of the multiple shelves 25 and is held by the shelf 25. Therefore, even if the partition wall bulge 22a is removed from the cap body 2, the solid object C2 does not fall into the storage space S1 formed in the container body 4, as shown by the two-dot chain line in FIG. 1. According to this embodiment, after the lid body 3 is removed, the partition wall bulge 22a of the cap body 2 is moved to the lid body 3 by being held by the retaining tube 32 of the lid body 3 so as not to come off. Therefore, according to this embodiment, the partition wall bulging portion 22a separated from the partition wall annular portion 22b will not fall.

[0046] 5 shows a state in which the content C1 of the container body 4 is taken out through the cap body 2 together with the solid matter C2 contained in the cap body 2. After opening the lid 3, by tilting the container body 4 as shown in FIG. 5, the solid matter C2 can be consumed together with the content C1 through the upper attachment tube 23 of the cap body 2.

[0047] According to container 10A, when container 10A is not in use, content C1 contained in container body 4 and solid matter C2 contained in cap 1A can be stored separately from each other as shown in Fig. 1. Furthermore, according to container 10A, when it is in use, it can be easily opened by simply rotating lid body 3 as shown in Fig. 5, and content C1 and solid matter C2 can be consumed at the same time.

[0048] Therefore, according to the container 10A, it is possible to store the solid matter C2 separately from the contents C1 contained in the container body 4, and at the time of use, they can be easily taken out at the same time.

[0049] Next, an example of a method for obtaining the cap body 2 according to this embodiment will be described. In this example, the cap body 2 is manufactured by injection molding using a mold.

[0050] Fig. 6 shows a schematic diagram of the mold shape of the cap body 2 according to this embodiment together with a part of the mold. As shown in Fig. 6, the mold shape of the cap body 2 according to this embodiment is such that the shelf portions 25 are inclined radially outward as they extend downward. In other words, the mold shape of the cap body 2 is formed such that the two shelf portions 25 facing each other across the axis O have a figure eight shape (a shape that flares outward) as they extend downward.

[0051] Fig. 6 shows the mold shape of the cap body 2 with only the mold M that forms the radially outer shape of the shelf portion 25 remaining. Fig. 7 also shows an enlarged example of the operation when the shelf portion 25 of the cap body 2 is formed in the appropriate position by removing the mold M shown in Fig. 6. Fig. 8 also shows a schematic of the cap body 2 formed by removing the mold M.

[0052] For example, referring to FIG. 6, when the mold M remaining on the cap body 2 immediately after injection molding is released as shown by the arrow, the mold M can be removed from the cap body 2. At this time, the mold M pushes the shelf portion 25 downward as shown by the arrow d1 in FIG. 7, and then pushes the shelf portion 25 upward from the base portion 25a as shown by the arrow d2. In this embodiment, the base portion 25a of the shelf portion 25 is connected to the extension tube 24 by a hinge. As a result, the shelf portion 25 is bent upward from the base portion 25a. Furthermore, the cap body 2 is provided with a stopper (26a) that contacts the shelf portion 25. Therefore, the shelf portion 25 is bent upward until the bent portion 25d of the shelf portion 25 contacts the stopper (26a). As a result, by removing the mold M remaining on the cap body 2 immediately after injection molding, the cap body 2 as shown in FIG. 8 can be obtained.

[0053] Therefore, by forming the base 25a of the shelf portion 25 with a hinge as in this embodiment, when the mold M is released after injection molding, the shelf portion 25 is in a state capable of supporting the solid C2 below the partition wall bulge portion 22a, and a cap body 2 can be easily obtained in an appropriate position so that the contents C1 can flow through the gap G.

[0054] In addition, as in this embodiment, when shelf portion 25 bends upward from base portion 25a, the bending of shelf portion 25 can be restricted by contacting stopper (26a), thereby allowing shelf portion 25 to be positioned in a more appropriate position.

[0055] 9 is a schematic diagram of a container 10B according to a second embodiment of the present invention. The container 10B is provided with a cap (container cap) 1B according to the second embodiment of the present invention. In this embodiment, the same reference numerals are used for parts that are substantially the same as those in the above embodiment.

[0056] In this embodiment, the engagement portion WS is composed of a recess 29 formed on the outer peripheral surface of the partition wall bulge 22a of the cap body 2 and a protrusion 39 provided on the inner peripheral surface of the retaining tube 32 of the lid body 3. In this embodiment, the recess 29 of the cap body 2 is a key groove (guide groove) formed on the outer peripheral surface of the small diameter portion 22a2 of the partition wall bulge 22a of the cap body 2. In this embodiment, the recess 29 extends in the axial direction over the entire outer peripheral surface of the small diameter portion 22a2. In contrast, in this embodiment, the protrusion 39 of the lid body 3 is a key (guide protrusion) provided on the inner peripheral surface of the retaining tube 32 of the lid body 3. The protrusion 39 of the lid body 3 extends in the axial direction from the top wall 31 to a position above the annular protrusion 32p on the inner peripheral surface of the retaining tube 32 of the lid body 3. In this embodiment, the convex portion 39 of the lid body 3 can be fitted into the concave portion 29 of the cap body 2 by first aligning the convex portion 39 with the concave portion 29 of the cap body 2, and then inserting the lid body 3 from top to bottom using the concave portion 29 as a guide groove.

[0057] The partition wall bulge 22a of the cap body 2 can be rotated integrally with the retaining tube 32 of the lid body 3 by fitting the recess 29 of the cap body 2 into the protrusion 39 of the lid body 3. As a result, in this embodiment, as in the first embodiment, the partition wall bulge 22a of the cap body 2 can be twisted in the circumferential direction around the axis O relative to the partition wall annular portion 22b while removing the lid body 3 from the cap body 2. By this twisting, in this embodiment, as in the first embodiment, the partition wall bulge 22a of the cap body 2 can be separated from the partition wall annular portion 22b while removing the lid body 3.

[0058] On the other hand, in this embodiment, when the lid body 3 is attached to the cap body 2, the lid body 3 is attached to the cap body 2 by pushing the lid body 3 from above the cap body 2. That is, in this embodiment, the lid body 3 is attached to the cap body 2 by plugging.

[0059] In FIG. 10, the force received from the holding jig that holds the cap body 2 when the lid body 3 is plugged into the cap body 2 to obtain the cap 1B is indicated by an arrow. When the lid body 3 is plugged, as shown by the arrow in FIG. 10, a holding jig (not shown) is arranged below the cap body 2 so that an upward force acts on each of the partition wall bulge portion 22a and the partition wall annular portion 22b of the cap body 2. In this embodiment, a rotation-stopping rib 24r is provided on the cap body 2 so that the cap body 2 does not rotate in the circumferential direction around the axis O relative to the holding jig when the lid body 3 is plugged. In this embodiment, the rib 24r is provided on the outer circumferential surface of the extension tube 24. In this embodiment, the rib 24r extends in the axial direction. The rib 24r is engaged with a guide groove (not shown) formed in the holding jig to stop the cap body 2 from rotating relative to the holding jig. This allows the lid body 3 to be plugged into the cap body 2 at a more accurate position.

[0060] Next, a description will be given of an example of a method of using the container 10B in Fig. 9. In this embodiment, the content C1 of the container body 4 and the solid matter C2 contained in the cap 1B are the content C1 and the solid matter C2 of the container 10A, respectively.

[0061] As shown in FIG. 9, in container 10B, like container 10A, the contents C1 contained in the storage space S1 of the container body 4 and the solid matter C2 contained in the storage space S2 of the cap 1B are prevented from touching each other when container 10B is not in use by the partition wall 22 of the cap body 2.

[0062] When using the container 10B, the lid 3 is rotated in the direction in which the screw is removed, similarly to the container 10A.

[0063] FIG. 11 shows the lid body 3 in a state where it is removed from the cap body 2. As shown in FIG. 11, in the container 10B, similarly to the container 10A, when the lid body 3 is removed from the cap body 2, an opening A2 formed by the radial inner edge (the portion to be cut 22c) of the partition wall annular portion 22b is formed in the cap body 2. The opening A2 communicates the storage space S1 formed in the container body 4 with the outside through the gap G. Also, according to this embodiment, even if the solid C2 falls inside the extension tube 24, it is held by the multiple shelf portions 25, similarly to the container 10A. Also, according to this embodiment, similarly to the container 10A, after the lid body 3 is removed, the partition wall bulge portion 22a of the cap body 2 moves to the lid body 3. Therefore, also in this embodiment, similarly to the container 10A, the partition wall bulge portion 22a separated from the partition wall annular portion 22b does not fall.

[0064] 12 shows a state in which the contents C1 of the container body 4 are taken out through the cap body 2 together with the solid matter C2 contained in the cap body 2. Similarly to the container 10A, after opening the lid 3, by tilting the container body 4 as shown in FIG. 12, the solid matter C2 can be consumed together with the contents C1 through the upper attachment tube 23 of the cap body 2.

[0065] Similarly to container 10A, container 10B can store content C1 contained in container body 4 and solid matter C2 contained in cap 1B separately when container 10B is not in use, as shown in Fig. 9. Similarly to container 10A, container 10B can be easily opened when in use by simply rotating lid 3, as shown in Fig. 12, and content C1 and solid matter C2 can be consumed at the same time.

[0066] Therefore, similar to container 10A, container 10B allows solid matter C2 to be stored separately from content C1 contained in container body 4, and allows these to be easily removed simultaneously when in use.

[0067] Next, an example of a method for obtaining the cap body 2 according to this embodiment will be described. In this example, the cap body 2 is manufactured by injection molding using a mold, similar to the cap body 2 according to the first embodiment.

[0068] 10, for example, in the cap body 2 according to this embodiment, the shelf portion 25 has a thin portion 25c that can bend the shelf portion 25 toward the lid body 3. In this embodiment, the thin portion 25c is formed at a position between the base portion 25a of the shelf portion 25 and the tip portion 25b of the shelf portion 25, closer to the base portion 25a than the tip portion 25b. Specifically, the thin portion 25c of the shelf portion 25 is disposed between the bent portion 25d and the shelf portion main body 25f.

[0069] Fig. 13 shows a schematic diagram of the mold shape of the cap body 2 according to this embodiment together with a part of the mold. As shown in Fig. 13, the mold shape of the cap body 2 according to this embodiment is inclined radially outward as the shelf portion 25 approaches the lower side, similar to the cap body 2 according to the first embodiment. The mold shape of the cap body 2 according to this embodiment is also shaped such that the two shelf portions 25 facing each other across the axis O are in a figure of eight (a shape that widens toward the end) as they approach the lower side, similar to the mold shape of the cap body 2 according to the first embodiment.

[0070] Figure 13 shows the mold shape of the cap body 2 with only the mold M remaining, which forms the radially outer shape of the shelf portion 25. Figure 14 also shows an enlarged example of the operation when the shelf portion 25 of the cap body 2 is formed in the appropriate position by releasing the mold M shown in Figure 13.

[0071] For example, referring to FIG. 13, the mold M remaining on the cap body 2 immediately after injection molding can be removed from the cap body 2 by releasing the mold M as shown by the arrow. At this time, the mold M pushes the shelf portion 25 downward as shown by the arrow d1 in FIG. 14, and then pushes the shelf portion 25 upward from the base portion 25a as shown by the arrow d2. The cap body 2 according to this embodiment is also provided with a stopper (26a) that contacts the shelf portion 25, as in the cap body 2 according to the first embodiment. Therefore, the shelf portion 25 bends upward until the bent portion 25d contacts the stopper (26a). Here, in this embodiment, the shelf portion 25 is further pushed upward from the thin portion 25c as shown by the arrow d3 in FIG. 14. This causes the shelf portion 25 to bend upward to a state closer to horizontal. As a result, by releasing the mold M remaining on the cap body 2 immediately after injection molding, it is possible to obtain a cap body 2 with the shelf portion 25 in a state closer to horizontal.

[0072] Therefore, as in this embodiment, by further providing the shelf portion 25 with a thin-walled portion 25c that enables the shelf portion 25 to bend toward the lid body 3, by simply releasing the mold M after injection molding, the shelf portion 25 in a more horizontal state can support the solid C2 below the partition wall bulge portion 22a, and the cap body 2 can be easily obtained in an appropriate position that allows the contents C1 to flow through the gap G.

[0073] The above is an exemplary embodiment of the present invention. Therefore, the present invention is not limited to the above embodiment, and various modifications can be made within the scope of the claims. For example, in this embodiment, the stopper (26a) extends in a ring shape in the circumferential direction around the axis O, as shown in FIG. 3. However, the stopper (26a) can be provided locally in accordance with the position where the shelf portion 25 is arranged on the extension tube 24. In addition, the various configurations adopted in each of the above-mentioned embodiments can be used in combination with each other. [Explanation of symbols]
