Detailed Description
Hereinafter, modes for carrying out the present utility model will be described with reference to the drawings, but the present utility model is not limited to the modes shown in the specification and drawings.
< embodiment 1 >
The container according to embodiment 1 of the present utility model is a double container with a lid, and includes a replaceable bottomed tubular inner container, an outer container accommodating the inner container, and a lid. Fig. 1 is a perspective view of a state in which constituent elements of a container 100 according to the present embodiment are combined, and fig. 2 is an exploded view of the container 100. Fig. 3 is a perspective view showing a structure (double container) 1 including an inner container 10 and an outer container 20 in a state where a lid 40 is detached from a container 100 according to the present embodiment. Fig. 4 is a section taken along line I-I of fig. 3, and is a section taken along the direction of extension of the axis AL of the container 100. In the present specification, the term "axial direction" refers to a direction along the axis (center line) AL of the tubular inner container 10. The axial direction is the axial direction of the entire container 100, and is also the axial direction of the outer container 20. The term "radial direction" means a direction from the center of the cylindrical inner container 10 toward the peripheral surface, the term "upper" or "upper" means an opening side of the container as viewed in the axial direction, and the term "lower" or "lower" means a side opposite to the opening as viewed in the axial direction, that is, a bottom surface side of the container.
As shown in fig. 1 to 3, the container 100 according to the present embodiment is a wide-mouth container. The wide-mouth container may be a container having an opening wide enough to allow a person's finger to be inserted into the opening. For example, the inner diameter (inner diameter of the opening or maximum inner diameter) of the container may be equal to or greater than the distance from the opening position to the bottom surface in the up-down direction. The inner diameter of the container 100 (i.e., the diameter of the opening 17 of the inner container 10) may be about 30-100 mm. Therefore, in the present embodiment, the container 100 is suitable for storing contents that are used by scooping up with a finger. The contained content is preferably a content having a high viscosity to a certain extent, such as a paste, gel, or mousse, and specifically may be a sanitary daily product such as a cosmetic product such as a cleansing cream, a facial cleanser, a cosmetic cream, or a moisturizing cream, a pasty hair treatment agent, a hair styling agent, or a body care agent.
The inner container 10 is a replaceable component (replacement container). On the other hand, the outer container 20 may be a member that is continuously used even if the inner container 10 is replaced, and information such as the raw material of the content and the method of use, decoration, and the like may be applied to the outer surface of the outer container 20.
The inner container 10 may be a bottomed cylindrical shape as described above, or may have a bottom 11 and a cylindrical portion 12 connected to the bottom 11. The inner diameter and/or the outer diameter of the cylindrical portion 12 may be fixed in the up-down direction, but may be changed, for example, may be smaller or larger as it is closer to the opening 17 (as it is to the upper side). As shown in fig. 3 and 4, the connecting portion between the bottom portion 11 and the cylindrical portion 12 may be a curved surface.
The cylindrical portion 12 of the inner container 10 includes: a peripheral wall portion 12a that constitutes a main portion of the tubular portion 12 and is in contact with the content; and an annular hanging portion 12b formed radially outward of the peripheral wall portion 12a and hanging from an upper edge 12t of the tubular portion 12 in the circumferential direction. In other words, the cylindrical portion 12 is folded back to the outside over the entire upper side, and the folded back portion is an annular hanging portion 12b. The length (height) of the annular hanging portion 12b in the axial direction is preferably fixed, and the length thereof may be 5 to 30mm. The peripheral wall portion 12a and the annular hanging portion 12b of the inner container 10 are separated in the radial direction, and a gap or a pocket opening downward is formed (fig. 4).
The outer container 20 may be a substantially cylindrical shape with a bottom, or may have a bottom 21 and a cylindrical portion 22 connected to the bottom 21. The outer container 20 may have a structure without the bottom 21 as long as it can support the inner container 10. In this case, when the double container 1 in which the inner container 10 is mounted on the outer container 20 is viewed from below, the inner container 10 can be exposed.
The diameter of the cylindrical portion 22 of the outer container 20 may be fixed or may be changed in the up-down direction. In the illustrated example, the tubular portion 22 includes a tubular portion main body 22a and an upper Fang Zhoubi portion 23 (fig. 2 to 4) that forms an upper portion with respect to the tubular portion main body 22 a. The upper Fang Zhoubi part 23 is a part having an inner diameter and an outer diameter smaller than those of the tubular part main body 22a, and a stepped part is formed at a transition part between the upper Fang Zhoubi part 23 and the tubular part main body 22 a. In a state where the inner container 10 and the outer container 20 are mounted, the upper Fang Zhoubi part 23 of the outer container 20 is disposed in a gap formed between the peripheral wall part 12a and the annular hanging part 12b of the inner container 10, and an outer peripheral surface of the upper Fang Zhoubi part 23 faces an inner peripheral surface of the annular hanging part 12b (fig. 4, which will be described later).
A lid 40 (fig. 1, 2, and 4) may be attached to the double container 1 in a state where the inner container 10 is attached to the outer container 20. Thereby, the opening 17 of the inner container 10 can be closed to protect the content from the external environment. In the example shown in fig. 1, the inner container 10 is not exposed in the state where the lid 40 is attached. Therefore, by making the cover 40 and the outer container 20 identical in appearance (including material, color, pattern, etc.), or by making the difference in contrast, a highly designed and aesthetically pleasing structure can be obtained. In order to seal the container 100 more tightly, a gasket or the like may be provided inside the lid 40. The lid 40 is formed to be screwed with the male screw portion 18m formed on the outer peripheral surface of the annular suspended portion 12b of the inner container 10. However, the lid 40 may be attached to the double container 1 by a form other than screwing, for example, fitting in the up-down direction.
In the present embodiment, the inner container 10 is mounted on the outer container 20 by screwing. In other words, the inner peripheral surface of the annular suspended portion 12b of the inner container 10 and the outer peripheral surface of the outer container 20 are engaged by screw-coupling. Specifically, the internal thread portion 18f formed on the inner peripheral surface of the annular hanging portion 12b of the inner container 10 is configured to be screwed with the external thread portion 28m formed on the upper Fang Zhoubi portion 23 of the outer container 20.
When the inner container 10 is mounted on the outer container 20, first, the axis AL of the inner container 10 and the axis AL of the outer container 20 are aligned to be close to each other in the up-down direction. Thereby, the upper Fang Zhoubi portion 23 of the outer container 20 can be inserted into the gap between the peripheral wall portion 12a and the annular hanging portion 12b of the inner container 10. Further, when the female screw portion 18f formed on the inner peripheral surface of the annular suspended portion 12b of the inner container 10 is in contact with the male screw portion 28m formed on the outer peripheral surface of the upper Fang Zhoubi portion 23 of the outer container 20 in the vertical direction, the inner container 10 is rotated relative to the outer container 20. In the illustrated example, the inner container 10 is rotated clockwise with respect to the outer container 20 as viewed from above, so that both can be screwed (screwed). The female screw portion 18f of the inner container 10 and the male screw portion 28m of the outer container 20 may be configured such that the screwing of both is performed until the upper Fang Zhoubi portion 23 of the outer container 20 abuts against the lower surface of the upper edge 12t of the tubular portion 12 of the inner container 10. The direction of the relative rotation for establishing the screw engagement between the inner container 10 and the outer container 20 is not limited, and may be counterclockwise.
Since the inner container 10 and the outer container 20 are screwed (screwed), the inner container 10 is only required to be rotated along the screw thread in order to be attached to the outer container 20, and therefore the attachment operation can be reliably performed by the guide of the screw thread. In addition, when the inner container 10 is temporarily attached to the outer container 20, the inner container 10 and the outer container 20 are engaged in the entire circumferential direction, so that they are reliably fixed in the up-down direction, and the possibility of separation of the two in the up-down direction against the intention of the user can be reduced.
In addition, conventionally, a portion for forming engagement (for example, engagement by fitting) needs a fine size structure, and for example, the engagement portion needs to be formed finely in the up-down direction, the radial direction, and the circumferential direction. Therefore, when a relatively fragile material or the like is used, the engagement portion may be easily damaged during production or worn during use, and a desired card or a desired card combination may not be obtained. Further, according to the material, for example, in a material having a small elasticity or viscoelasticity, when the dimension unevenness occurs in the engagement portion, the dimension unevenness is directly reflected in the unevenness of the engagement force, and an appropriate engagement may not be obtained. For example, there are situations where the engagement is too tight to be operated by the user, or conversely where the engagement is too loose to create a sloshing of the inner container in use. In contrast, according to the present embodiment, the inner container 10 and the outer container 20 are attached by screwing, and thus, appropriate engagement is obtained regardless of the material, and the range of selection of the material for the container, particularly the material for the outer container 20, is widened. Therefore, in view of design, aesthetic properties, and the like, for example, even if the outer container 20 is formed of glass, ceramic, or the like, the engagement between the inner container 10 and the outer container 20 can be firmly configured. Therefore, even if the outer container 20 is reused, the replacement of the inner container 10 can be smoothly performed, and the inner container 10 and the outer container 20 can be prevented from being separated from each other beyond the intention of the user.
Further, in the present embodiment, a locking piece 15 (fig. 2 to 4) that can be engaged with the outer container 20 is formed on the cylindrical portion 12, more specifically, the annular hanging portion 12b of the inner container 10. As shown in fig. 2 to 4, the locking piece 15 may be a member that is at least partially cut out from the annular hanging portion 12b and movable in the radial direction. In the illustrated example, the locking piece 15 is integrally formed with the inner container 10, but the locking piece 15 may be separate from the inner container 10. The term "radially displaceable" means that a part or all of the locking piece 15 is displaced in the radial direction, and may include that a part of the locking piece 15 is displaced in the radial direction by deforming the locking piece 15, or may include that the whole locking piece 15 is displaced in the radial direction. In the illustrated example, the locking piece 15 is a cantilever spring member (fig. 3) having a fixed end 15a connected to the tubular portion 12 (more specifically, the annular hanging portion 12 b) of the inner container 10 and a free end 15b separated from the tubular portion 12 (more specifically, the annular hanging portion 12 b). The entire locking piece 15 can be elastically deformed with the fixed end 15a as a base. The extending direction extending from the fixed end 15a to the free end 15b of the locking piece 15 is a circumferential direction. Then, the locking piece 15 can be opened radially outward about the fixed end 15 a. The length of the locking piece 15, that is, the length from the fixed end 15a to the free end 15b may be 5 to 15mm.
Next, the function of the locking piece 15 will be described with reference to fig. 5A, 6B, and 6. Fig. 5A, 5B, and 6 are cross-sectional views (corresponding to the line II-II cross section in fig. 4) taken along a direction (horizontal direction) orthogonal to the axial direction of the container 100 at positions including the locking piece 15. However, fig. 5A and 5B show a state in which the cover 40 is not present, and fig. 6 shows a state in which the cover 40 is attached.
As shown in fig. 5A, the locking piece 15 is connected to the annular hanging portion 12b of the inner container 10 through a fixed end 15A in the circumferential direction. Further, a protrusion 15c protruding radially inward may be formed on the free end 15b located on the opposite side of the fixed end 15a in the circumferential direction. The area of the end face of the free end 15b becomes large due to the presence of the protrusion 15c. On the other hand, a convex portion 23p protruding radially outward is formed on the outer peripheral surface of the upper Fang Zhoubi portion 23 of the outer container 20. The projection 15c of the locking piece 15 overlaps with the convex portion 23p formed on the outer peripheral surface of the outer container 20 as viewed in the radial direction. Therefore, when the inner container 10 is rotated relative to the outer container 20, the end surface of the free end 15b of the locking piece 15 is in contact with the protruding portion 23p in the circumferential direction (fig. 5A). However, since the locking piece 15 is elastically deformable radially outward as described above, in particular, in the illustrated example, the locking piece 15 can be opened radially outward (in the direction of arrow A3) to pass over the protruding portion 23p regardless of rotation in the direction of arrow A1 (in the direction in which the inner container 10 is attached to the outer container 20) or the direction of arrow A2 (in the direction in which the inner container 10 is detached from the outer container 20).
Fig. 5B is a view showing a state in which the state in fig. 5A is rotated further in the direction of arrow A2, that is, in the direction in which the inner container 10 is disengaged from the outer container 20 by releasing the screwing of the inner container 10 and the outer container 20. As shown in fig. 5B, the locking piece 15 is elastically deformed and opened radially outward, and is positioned radially outward of the protruding portion 23p of the outer container 20. When the inner container 10 is further rotated in the direction of arrow A2 from the state of fig. 5B, the projection 15c of the locking piece 15 can pass over the convex portion 23p. Thus, in the state of fig. 5A and 5B (the state in which the lid 40 is not attached), the inner container 10 and the outer container 20 can relatively rotate. Therefore, when the inner container 10 is to be replaced, the user can detach the inner container 10 by holding the inner container 10, for example, the annular hanging portion 12b, and rotating it relative to the outer container 20.
In contrast, when the cover 40 is further attached in the state shown in fig. 5A and 5B, the operation of the locking piece 15 is different. As shown in fig. 1 and 4, the lid 40 is provided to cover the outer peripheral surface of the annular hanging portion 12b of the inner container 10. More specifically, the female screw portion 48f formed on the inner peripheral surface of the lid body 40 is screwed with the male screw portion 18m formed on the outer peripheral surface of the annular suspended portion 12b (fig. 4). The cover 40 covers the annular hanging portion 12b so as to cover the locking piece 15, and faces the locking piece 15 in the radial direction. The cover 40 is arranged radially outward of the locking piece 15 as viewed in cross section as shown in fig. 6. Therefore, when the locking piece 15 is to be displaced radially outward (in the direction of arrow A3), the displacement of the locking piece 15 is blocked by the cover 40. Due to such a restriction of displacement (deformation) in the radial direction, the projection 15c of the locking piece 15 cannot pass over the convex portion 23p formed on the outer peripheral surface of the outer container 20 in the circumferential direction. Therefore, when the inner container 10 is rotated relative to the outer container 20 in a direction in which the screwing of the inner container 10 and the outer container 20 is released, that is, in a direction in which the inner container 10 is detached from the outer container 20 (in a direction of an arrow A2), the free ends 15b of the locking pieces 15 come into contact with the protruding portions 23p in the circumferential direction. Further, the rotation of the inner container 10 in the direction of arrow A2 from the contact state is restricted, and the loosening of the screw engagement between the inner container 10 and the outer container 20 can be prevented. In this way, the locking piece 15 of the present embodiment provided in the inner container 10 can lock the outer container 20 in the circumferential direction.
The restriction of the relative rotation of the lid 40 described above means that the inner container 10 and the outer container 20 cannot be separated in a state where the lid 40 is attached. In the case of the conventional method in which the engagement between the locking piece 15 and the protruding portion 23p is not provided, the inner container 10 is detached from the outer container 20 even in the state in which the lid 40 is attached, and therefore, when the lid 40 and the inner container 10 are firmly screwed together, a phenomenon (also referred to as co-rotation) occurs in which the lid 40 and the inner container 10 are rotated together relative to the outer container 20. In this case, the user needs to remove only the lid 40 to expose the inner container 10 when using the container, but if the lid 40 and the inner container 10 are integrated and detached from the outer container 20, the opening 17 of the container 100 is not exposed, and thus the user cannot reach the content. Therefore, the cover 40 is detached from the inner container 10, and the inner container 10 is attached to the outer container 20 again, which is inconvenient. In contrast, according to the present embodiment, since the rotation of the inner container 10 with respect to the outer container 20 is restricted in the state where the lid 40 is covered, the user can use the content by removing only the lid 40 without requiring a special effort.
As shown in fig. 3 and 4, the locking piece 15 is disposed outside the range of the annular hanging portion 12b in which the male screw portion 18m is formed, more specifically, on the lower side of the range in which the male screw portion 18m is formed, as viewed from the top and bottom. This makes it possible to form the locking piece 15 without overlapping the thread, and thus the design becomes simpler. Further, the locking piece 15 is preferably disposed lower than the range of the annular hanging portion 12b in which the female screw portion 18f is formed.
The materials of the inner container 10 and the outer container 20 are not particularly limited. The material may be a resin or may be formed of other materials that are more brittle than resins, such as glass, ceramic, porcelain, etc. Alternatively, the material may be a metal or the like. However, if at least the locking piece 15 is formed of resin, elastic deformation in the radial direction is possible, so that it is preferable. The annular hanging portion 12b is preferably formed of the same resin as the locking piece 15 throughout the inner container 10, and the inner container 10 including the locking piece 15 is preferably integrally formed of the same resin. Specific examples of the resin include Polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polystyrene (PS), and polylactic acid (PLA), and among these, polypropylene (PP) is preferable. Resin may be used as the material of the outer container 20, but glass may be used because it is strong and gives a high-quality impression. In the present embodiment, even when the outer container 20 is formed of glass, a structure in which the possibility of damage is small and the inner container 10 and the outer container 20 can be appropriately engaged and disengaged can be obtained.
Fig. 7 shows the form in which the inner container 10 described above is used as a refill container 120. The refill container 120 includes an inner container 10 and a temporary lid 30. When the user replaces the inner container 10, the refill container 120 can be attached to the outer container 20 with the temporary lid 30 provided, and then the temporary lid 30 can be removed. This can prevent the content from overflowing during the process of attaching the inner container 10 to the outer container 20. Temporary lid 30 may be an aluminum film (aluminum seal) or the like that is detachably attached to upper edge 12t of inner container 10 and seals inner container 20.
< embodiment 2 >
Fig. 8 shows a state in which the lid body of the container 200 according to embodiment 2 is removed, that is, a combined body 201 of the inner container and the outer container (double container). The container 200 according to embodiment 2 has the same basic structure as the container 100 (fig. 1 to 6) according to embodiment 1. That is, the container comprises a replaceable bottomed tubular inner container 210, an outer container 220 accommodating the inner container 210, and a lid (not shown), and the inner container 210 is screwed to the outer container 220. The inner container 210 has a bottom and a cylindrical portion 212. The tubular portion 212 includes a peripheral wall portion 212a and an annular hanging portion 212b hanging from an upper edge 212t outside the peripheral wall portion 212a, and the annular hanging portion 212b is formed with a locking piece 215. In addition, the outer container 220 has a bottom 221 and a cylindrical portion 222. The upper Fang Zhoubi portion 223 of the tubular portion 222 is disposed in a gap between the peripheral wall portion 212a and the annular hanging portion 212b of the inner container 210. The inner container 210 and the outer container 220 are engaged by screwing the female screw portion of the annular hanging portion 212b of the inner container 210 and the male screw portion 223m of the upper Fang Zhoubi portion 223 of the outer container 220. However, in embodiment 2, the structure of the locking piece 215 and its periphery is different.
The locking piece 215 is formed in a range in the up-down direction in which the male screw portion 18m is formed in the annular hanging portion 212b of the inner container 210, unlike the locking piece 15 in embodiment 1. Therefore, the male screw portion 218m (screw portion formed on the outer peripheral surface of the annular hanging portion 212 b) of the inner container 210 is discontinuous in the middle of the circumferential direction, and the locking piece 215 is formed in the discontinuous portion. In this way, by forming the locking piece 215 within the range of the inner container 210 where the male screw portion 218m is formed, the length of the annular hanging portion 212b in the up-down direction can be shortened. Thus, the range of design choices can be increased, and the material of the inner container 10 can be saved.
The locking piece 215 is also a member which is cut out from the annular hanging portion 212b and can be displaced in the radial direction, similarly to the locking piece 15 (fig. 2 to 6) in embodiment 2. The locking piece 215 may be a cantilever spring member having a fixed end 215a connected to the inner container 210 (annular hanging portion 212 b) and a free end 215b separated from the inner container 210. The extending direction of the locking piece 215, that is, the extending direction extending from the fixed end 215a to the free end 215b is the circumferential direction.
In the present embodiment, the radial thickness of the locking piece 215 increases from the fixed end 215a toward the free end 215 b. The locking piece 215 is located radially inward on the fixed end 215a side, without being flush with the outer peripheral surface of the annular hanging portion 212 b. According to the shape of the locking piece 215, elastic deformation with the fixed end 215a as a base is easier.
Fig. 9 is a cross section of the container 200 according to embodiment 2 taken along a plane orthogonal to the axial direction at a position including the locking piece 215. Fig. 9 is a diagram corresponding to fig. 5A, 5B, and 6 referred to in the description of embodiment 1. As shown in fig. 9, the locking piece 215 has a protrusion 215c protruding radially inward on one side of the free end 215b, and thus the area of the end surface of the free end 215b increases. On the other hand, the outer peripheral surface of the upper Fang Zhoubi part 223 of the outer container 220 is formed with the male screw portion 228m, but the thread of the male screw portion 228m has the discontinuous portion 229. In the state shown in fig. 9, the protrusion 215c is fitted into the discontinuous portion 229 of the thread of the male screw portion 228m, and the locking piece 215 is in an unstressed state.
As described above, since the locking piece 215 is radially displaceable, more specifically, radially elastically deformable, when rotated in either one of the direction of arrow A1 (the direction in which the inner container 210 is attached to the outer container 220) and the direction of arrow A2 (the direction in which the inner container 210 is detached from the outer container 220) from the state shown in fig. 9, the locking piece 215 can be opened radially outward (the direction of arrow A3) and moved to the outside of the thread of the male screw portion 228m of the outer container 220. In particular, when the inner container 210 is relatively rotated with respect to the outer container 220 in the direction of arrow A2 in order to detach the inner container 210 from the outer container 220, the protrusion 215c of the locking piece 215 can pass over a part (the convex portion 223 p) of the male screw portion 228 m.
In contrast, in fig. 9, the position of the cover 240 in the case where the cover 240 is attached is indicated by a one-dot chain line. When the cover 240 is attached, the cover 240 is positioned radially outward of the locking piece 215, and movement of the locking piece 215 radially outward is suppressed. Therefore, when the locking piece is rotated relative to each other in the direction of arrow A2, the end surface of the free end 215b of the locking piece 215 is in contact with a part (convex portion 223 p) of the thread of the male screw portion 228m in the circumferential direction, and no more relative rotation is caused. Accordingly, in the state where the lid 240 is attached, the relative rotation in the direction in which the inner container 210 is detached from the outer container 220 (rotation in the direction of arrow A2) is restricted, that is, the outer container 220 is locked in the circumferential direction by the locking piece 215 of the inner container 210, and therefore, the inner container 210 is not locked from the outer container 220. As in embodiment 1, when the lid 240 is to be removed, the inner container 210 can be prevented from rotating relative to the outer container 220, and not only the lid 240 but also the inner container 210 can be rotated together to come off, so-called co-rotation.
Although the portion (the convex portion 223 p) where the free end 215b of the locking piece 215 abuts in the circumferential direction becomes a part of the male screw portion 228m of the outer container 220 in the illustrated example, the convex portion 223p having the same function as the 23p described in embodiment 1 may not necessarily be a part of the male screw portion 228 m. The convex portion 223p may be a portion formed in a position, shape, and size separated from the thread of the male screw portion 228, as long as the free end 215b of the locking piece 215 abuts in the circumferential direction.
In the present embodiment, as shown in fig. 8 and 9, the locking piece 215 may overlap with the thread of the male screw portion 223m of the upper Fang Zhoubi portion 223 of the outer container 220 in the vertical direction. In this case, a groove may be formed in the inner peripheral surface side of the locking piece 215 in a portion other than the projection 215c in the circumferential direction.
In the present embodiment, an opening 216 is formed in the annular hanging portion 212b of the inner container 210. The locking piece 215 is formed at an edge portion of the circumferential end portion of the opening 216. The opening 216 may extend circumferentially within a range of 1.5 times or more the circumferential length of the locking piece 215 (fig. 8). Such an opening 216 is preferable in terms of facilitating smooth screwing of the inner container 210 and the outer container 220, or in terms of manufacturing in the case of using injection molding, a casting mold, or the like.
< embodiment 3 >
Fig. 10 shows a container 300 with a lid removed, that is, a combination 301 of an inner container and an outer container (double container), according to embodiment 3. The container 300 according to embodiment 3 has the same basic structure as the container 100 (fig. 1 to 6) according to embodiment 1 and the container 200 (fig. 8 and 9) according to embodiment 2. That is, the container comprises a replaceable bottomed tubular inner container 310, an outer container 320 accommodating the inner container 310, and a lid (not shown), wherein the inner container 310 is screwed to the outer container 320. The inner container 310 has a bottom portion and a cylindrical portion 312. The tubular portion 312 has a peripheral wall portion 312a and an annular hanging portion 312b hanging from an upper edge 312t outside the peripheral wall portion 312a, and the annular hanging portion 312b is formed with a locking piece 315. In addition, the outer container 320 has a bottom 321 and a cylindrical portion 322. The upper Fang Zhoubi portion 323 of the tubular portion 322 is disposed in a gap between the peripheral wall portion 312a and the annular hanging portion 312b of the inner container 310. The inner container 310 and the outer container 320 are engaged by screwing the female screw portion of the annular hanging portion 312b of the inner container 310 and the male screw portion 328m of the upper Fang Zhoubi portion 323 of the outer container 320.
The function of the locking piece 315 in embodiment 3 is also similar to that of the locking piece 215 in embodiment 2, and the locking piece 215 locks the outer container 320 in the circumferential direction. However, in embodiment 3, the difference is that the external screw thread portion is not formed in the annular hanging portion 312b of the inner container 310, unlike embodiment 2. That is, in the present embodiment, the lid (not shown) is screwed not with the inner container 310 but with the outer container 320. Therefore, it is more preferable in view of the fact that the phenomenon of co-rotation, which may occur when the lid and the inner container 310 are firmly coupled as described in embodiment 1 and embodiment 2, is not easily generated.
The present utility model has been described above with reference to specific embodiments thereof with reference to the drawings, but these embodiments are merely provided as examples, and the present utility model is not limited to the above embodiments. Various changes, modifications, substitutions, deletions, additions, combinations, and the like may be made within the scope of the present disclosure.
