Summary of the Invention

Problems to be Solved by the Invention

[0004] Many of this type of compact container are sized to fit in one hand, and it is required to be easily opened with one hand, for example, by a one-touch operation. However, with the above conventional compact container, it is difficult to perform an opening operation with one hand, and it is necessary to perform the opening operation using both hands. Specifically, for example, while holding the container body with one hand, it is necessary to lift the lid body with the other hand to release the undercut fitting between the lid body side engaging portion and the lid closing engaging portion. Therefore, it is difficult to perform an opening operation with one hand, and there is room for improvement.

[0005] In particular, the need to use both hands to open it makes it cumbersome and inconvenient to use. Furthermore, if the undercut fit is strong, it becomes even more troublesome as it requires opening the lid by, for example, inserting your fingertips into the gap between the container body and the lid while pulling up the lid.

[0006] This invention has been made in view of these circumstances, and its purpose is to provide a compact container that can be easily opened with one hand. [Means for solving the problem]

[0007] (1) The compact container according to the present invention comprises a bottomed cylindrical container body having a circumferential wall including a front wall and a rear wall facing each other in the front-rear direction and having a storage space inside, and a toped cylindrical lid that is rotatably connected to the container body via a pivot piece positioned behind the rear wall and opens and closes the storage space, wherein the container body has a first engaging projection formed on the front wall and projecting forward, and a support portion formed on the rear wall and facing the pivot piece in the left-right direction, and the lid has an engaging piece that projects rearward and has a second engaging projection formed thereon that engages with the first engaging projection detachably from below, and the pivot piece is rotatably connected to the support portion via a shaft extending in the left-right direction, The rotating piece and the support member have a rotating hole formed in the shape of an elongated hole that is longer in the front-rear direction than the diameter of the shaft, through which the shaft is inserted in the left-right direction. The lid is assembled to move forward relative to the container body by the amount of the gap between the rotating hole and the shaft when the lid is closed relative to the container body. An elastic body is provided between the rear wall and the rotating piece that elastically deforms as the lid moves forward. The front wall has a guiding surface that guides the engaging piece forward to release the engagement between the first engaging projection and the second engaging projection as the lid moves forward, while also guiding the engaging piece upward.

[0008] In the compact container according to the present invention, a second engaging projection formed on the engaging piece of the lid engages with a first engaging projection formed on the front wall of the container body from below, so that the lid can be kept closed relative to the container body. This prevents the lid from opening unintentionally during product distribution, storage (when not in use), etc. When using the compact container, for example, the container body is held with the right hand, and the lid is pressed forward with the fingertips of the right hand. This allows the entire lid to slide relative to the container body, while the elastic body is elastically deformed by the gap between the pivot hole and the shaft. This allows the engaging piece to be guided forward to release the engagement between the first engaging projection and the second engaging projection, using the guiding surface formed on the front wall, and further guided to push the engaging piece upward.

[0009] Therefore, the lid can be flipped upward relative to the container body, allowing the lid to be opened with a single touch. Furthermore, because the lid is flipped upward, even if the lid returns to its original position backward due to the elastic restoration deformation of the elastic body when the forward sliding operation of the lid is released, it is possible to prevent the second engaging projection from re-engaging with the first engaging projection. Thus, the lid can be maintained in the flipped-up position.

[0010] As a result of the above, one-handed operation is possible with a single touch, allowing for easy opening with one hand. Therefore, the lid can be opened using the shaft and rotating piece, and tools such as applicators can be taken out of the container's storage space and used. Furthermore, since an elastic body is provided between the rear wall and the rotating piece, when the lid is flipped upward, the elastic restoration deformation of the elastic body presses the rotating piece backward, providing resistance to the rotating piece. In addition, since the elongated rotating hole rotates along with the rotation of the lid, the shaft and the rotating hole can be made to contact without any gaps. As a result, even though the rotating hole is elongated, the lid can be used while fixed at any opening angle, for example. In other words, a free-stop function can be achieved. Therefore, it is possible to make a compact container that is easy to use.

[0011] (2) The elastic body is formed in a sheet-like form of a softer material than the container body and the lid, and when the lid is closed, it is positioned in a compressed state between the rear wall and the rotating piece, and may bias the lid toward the rear by elastic restoration deformation.

[0012] In this case, since the elastic body is formed in a sheet shape, the elastic body can be provided without securing a large space between the rear wall and the rotating piece. Therefore, it can contribute to further miniaturization. Furthermore, by utilizing the elastic body, the lid can be biased toward the rear even when the lid is in the closed position, so the first engaging projection and the second engaging projection can be engaged more firmly. This makes it possible to more effectively prevent the lid from opening unintentionally.

[0013] (3) The front wall has a support surface formed thereon which is positioned in front of the first engaging projection and supports the engaging piece from below, and the guiding surface may be formed integrally with the support surface and inclined to extend upward as it faces forward.

[0014] In this case, the engaging piece of the lid can be supported from below using the support surface, thus maintaining a more stable engagement between the first and second engaging projections. Furthermore, since the guiding surface is formed to be inclined toward the support surface, the engaging piece can be guided in a more stable state, allowing the lid to be smoothly flipped upwards. [Effects of the Invention]

[0015] According to the present invention, an easy-to-open operation can be performed with one hand, and a compact container that is easy to use can be obtained.

Embodiments for Carrying Out the Invention

[0017] Hereinafter, embodiments of the compact container according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the compact container 1 of the present embodiment is a flat container having a square shape in plan view. The compact container 1 includes a bottomed cylindrical container body 2 having an accommodation space S inside, and a toped cylindrical lid body 3 that is rotatably connected to the container body 2 via a rotating piece 50 and closes the accommodation space S in an openable manner.

[0018] Although the contents of the accommodation space S of the container body 2 are not particularly limited, for example, various members related to cosmetic products are accommodated. For example, a saucer containing contents such as cosmetics such as foundation and eyeshadow may be accommodated in the accommodation space S, or various applicators may be accommodated in addition to the saucer.

[0019] As shown in FIGS. 1 and 2, in the state where the lid body 3 is closed (closed lid state), the container body 2 and the lid body 3 are arranged such that their respective central axes are located on a common axis. In the present embodiment, this common axis is referred to as the container axis O, the side of the lid body 3 along the container axis O is defined as upward, and the side of the container body 2 is defined as downward. Furthermore, in a plan view seen from the direction of the container axis O, one direction that intersects the container axis O and is orthogonal to each other is defined as the front-back direction L1, and the other direction is defined as the left-right direction L2. Furthermore, the side of the rotating piece 50 in the front-back direction L1 is defined as the rear, and the opposite side is defined as the front.

[0020] The container body 2 and the lid body 3 are formed in a square shape in plan view where the length in the front-back direction L1 and the length in the left-right direction L2 are equal as described above. However, the shapes of the container body 2 and the lid body 3 are not limited to this case, and may be appropriately changed, for example, a rectangular shape, a circular shape, an elliptical shape, a polygonal shape, etc. in plan view. The container body 2 and the lid body 3 are rotatably connected via a rotating piece 50 and a shaft body 55 described later that extends in the left-right direction L2. As a result, the lid body 3 can be opened and closed in the front-back direction L1 around the shaft body 55.

[0021] (Container body) As shown in Figures 1 to 4, the container body 2 comprises a bottom wall 10 and a peripheral wall 11 extending upward from the outer peripheral edge of the bottom wall 10, and is formed in a bottomed cylindrical shape with an upward opening, and as mentioned earlier, is formed in a square shape in plan view. The peripheral wall 11 comprises a front wall 12 and a rear wall 13 facing each other in the front-rear direction L1, and a pair of side walls 14 facing each other in the left-right direction L2.

[0022] At the upper ends of the front wall 12 and the pair of side walls 14, a stepped portion 15 is formed that extends continuously downward across the front wall 12 and the pair of side walls 14. The formation of the stepped portion 15 creates a front bulkhead 12a on the front wall 12 that protrudes upward and extends in the left-right direction L2. Furthermore, the formation of the stepped portion 15 creates a pair of side bulkheads 14a on the side walls 14 that protrude upward and extend in the front-rear direction L1 and are connected to the front bulkhead 12a. Furthermore, the upper opening edge of the front bulkhead 12a and the upper opening edges of the pair of lateral bulkheads 14a are formed flat and flush with the upper opening edge of the rear wall 13.

[0023] The front partition wall 12a, which constitutes the front wall 12, has a first engaging projection 20 that protrudes forward. As shown in Figures 4 and 5, the first engaging projection 20 is formed in the portion of the front partition wall 12a that is located in the center in the left-right direction L2. The first engaging projection 20 includes an inclined guide surface 21 that extends downward from the upper opening edge of the front partition wall 12a as it moves forward, and an engaging surface 22 that curves backward from the lower end of the guide surface 21 and then extends downward as it moves backward. The first engaging projection 20 is formed to extend along the left-right direction L2.

[0024] Furthermore, the front wall 12 has a support surface 25 that is positioned in front of the first engaging projection 20 and supports the engaging piece 45, which will be described later, from below. The support surface 25 is formed on the stepped portion 15 so as to be recessed below the upper surface of the stepped portion 15, and is also formed to be horizontally elongated along the left-right direction L2 in a plan view. In the illustrated example, the support surface 25 is formed to be horizontally elongated over almost the entire length of the front wall 12. The support surface 25 is a flat surface facing upward. A certain gap is formed in the vertical direction between the support surface 25 and the engagement surface 22 of the first engagement projection 20.

[0025] Furthermore, a guide surface 26 is formed on the front wall 12. The guide surface 26 is formed on the upper surface of the stepped portion 15 so as to be located in front of the support surface 25, and is formed integrally with the support surface 25. In a plan view, the guide surface 26 is formed along the entire length of the support surface 25, and is formed to be horizontally elongated along the left-right direction L2. Furthermore, the guide surface 26 is an inclined surface that slopes upward as it extends forward from the support surface 25. In the illustrated example, the guide surface 26 is formed such that the height of the uppermost part of the guide surface 26 is equal to or greater than the height of the lowest end of the first engagement projection 20 (the connection point between the engagement surface 22 and the inner surface of the front partition wall 12a).

[0026] The aforementioned guiding surface 26 has the function of guiding the engaging piece 45 of the lid 3 forward as the lid 3 moves forward, while simultaneously guiding the engaging piece 45 to push upward. This will be explained in detail later.

[0027] As shown in Figures 1, 3, and 4, a support piece (support part according to the present invention) 30 protruding toward the rear is formed on the rear wall 13 of the container body 2. The support pieces 30 are formed to protrude backward from portions of the rear wall 13 located on both sides in the left-right direction L2. Therefore, a pair of support pieces 30 are provided with a gap in the left-right direction L2. Of the support pieces 30, the surfaces facing each other in the left-right direction L2 are the rotatable surfaces 31 that rotatably support the rotatable piece of the lid 3.

[0028] (Lid) As shown in Figures 1 to 4, the lid 3 is formed in a square shape in plan view, corresponding to the shape of the container body 2, and is formed in a top-mounted cylindrical shape with a top wall 40 that closes the container body 2 from above, and an outer frame 41 that extends downward from the outer peripheral edge of the top wall 40.

[0029] The outer frame 41 comprises a front frame 42 positioned in front of the front bulkhead 12a, a rear frame 43 positioned behind the rear wall 13, and a side frame 44 positioned outside the pair of side bulkheads 14a in the left-right direction L2. The lower end opening edges of the front frame 42, side frame 44, and rear frame 43 are formed flat.

[0030] When the lid 3 is closed over the container body 2, the front frame 42 and the side frame 44 contact the upper surface of the stepped portion 15 of the container body 2 from above. As a result, the lid 3 is positioned vertically and overlaps the container body 2. The rear frame 43 is positioned behind the rear wall 13 of the container body 2, with a gap between them.

[0031] When the lid 3 is closed over the container body 2, a gap is formed between the upper opening edge of the front partition wall 12a and the upper opening edge of the side partition wall 14a and the top wall 40 (see Figures 1 and 2). Therefore, this gap can be effectively utilized to attach a mirror to the inner surface of the top wall 40. For the mirror, for example, a thin plate, sheet, or film-shaped mirror can be used, and it can be attached by bonding with adhesive or double-sided tape, or by other methods of fixing. Furthermore, a mirror may be provided on the inner surface of the ceiling wall 40 by methods such as depositing a metal reflective film.

[0032] An engaging piece 45 is formed at the lower end of the front frame 42, protruding downward. The engaging piece 45 is formed to contact the support surface 25 and the guide surface 26 formed on the container body 2 from above. Therefore, the engaging piece 45 is formed to extend horizontally along the left-right direction L2 in a plan view, corresponding to the support surface 25 and the guide surface 26. Furthermore, a part of the lower end surface of the engaging piece 45 is inclined to correspond to the guide surface 26. As a result, when the lid 3 is closed to the container body 2, the engaging piece 45 can make close contact with the support surface 25 and the guide surface 26 from above.

[0033] Furthermore, the engaging piece 45 has a second engaging projection 46 that protrudes toward the rear and is detachably undercut fitted to the first engaging projection 20 formed on the container body 2. The second engaging projection 46 is longer in the left-right direction L2 than the first engaging projection 20 and is formed to bulge toward the rear in a hemispherical shape when viewed in a vertical cross-section. The second engaging projection 46 engages with the engaging surface 22 of the first engaging projection 20 from below. The lid 3 is locked in the closed position by the engagement (undercut fitting) of the second engaging projection 46 with the first engaging projection 20.

[0034] A rotating piece 50 is formed on the rear portion of the top wall 40 of the lid 3, extending downward. The rotating piece 50 is integrally formed with the top wall 40 and the rear frame 43, and is formed to protrude downward from the rear frame 43. In a side view, the rotating piece 50 is formed to protrude downward in a semicircular shape. Furthermore, a pair of rotating pieces 50 are provided spaced apart in the left-right direction L2, and are positioned inward in the left-right direction L2 from the pair of support pieces 30 formed on the container body 2. As a result, each of the pair of rotating pieces 50 is positioned opposite the pair of support pieces 30 in the left-right direction L2, and is positioned adjacent to the pair of support pieces 30 in a sliding contact state. Of the rotating piece 50, the surface facing the rotating surface 31 of the support piece 30 in the left-right direction L2 is defined as the rotating surface 51 (see Figure 4).

[0035] Furthermore, connecting ribs 52 are integrally formed on the top wall 40 and the rear frame 43 (see Figure 4). The connecting ribs 52 are formed to extend in the left-right direction L2 in a plan view, and connect a pair of rotating pieces 50 in the left-right direction L2. As a result, the pair of rotating pieces 50 are integrally combined via the connecting ribs 52, and have high rigidity. Therefore, unintended displacements such as tilting in the left-right direction L2 of the pair of rotating pieces 50 are suppressed.

[0036] Each of the pair of pivot pieces 50 configured as described above is rotatably connected to a pair of support pieces 30 via a shaft 55 extending in the left-right direction L2. In the illustrated example, the shaft 55 is a cylindrical boss integrally formed on the pivoted surface 31 of the pair of support pieces 30. The shaft 55 is formed to protrude inward in the left-right direction L2 from the pivoted surface 31 of the pair of support pieces 30.

[0037] In contrast, each of the pair of rotating pieces 50 has a rotating hole 56 through which the shaft 55 is inserted in the left-right direction L2. The rotating hole 56 is formed to be recessed inward in the left-right direction L2 from the rotating surface 51 of the rotating piece 50. However, this is not limited to this case; for example, the rotating hole 56 may be formed so as to penetrate the rotating piece 50 in the left-right direction L2. The pivot hole 56 is formed at the center (semicircular center) of the pivot piece 50 and is formed in an elongated or elliptical shape that is longer in the front-rear direction L1 than the diameter of the shaft body 55. Therefore, as shown in Figures 1 and 3, a gap is formed between the shaft body 55 and the pivot hole 56.

[0038] (Elastic body) As described above, the lid 3 is assembled to move forward relative to the container body 2 by the amount of the gap between the shaft 55 and the pivot hole 56, as shown in Figures 1 and 6, when the lid is closed relative to the container body 2. As shown in Figures 1, 3, 4, and 6, an elastic body 60 is provided between the rear wall 13 of the container body 2 and the pivot piece 50 of the lid 3, which elastically deforms as the lid 3 moves forward. In the illustrated example, the elastic body 60 is formed in a sheet-like shape of a softer material than the container body 2 and the lid 3, and is provided on the rear wall 13 in the inner part of the pair of support pieces 30 in the left-right direction L2. Specifically, the elastic body 60 is made of a soft material such as elastomer and is integrally formed with the rear wall 13 by, for example, two-color molding or insert molding.

[0039] In particular, the elastic body 60 is positioned in a compressed state between the rear wall 13 and the rotating piece 50, and biases the lid 3 toward the rear by elastic restorative deformation (see Figure 1). As a result, the shaft 55 is in contact with the inner surface on the front side of the rotating hole 56, and a gap is formed on the rear side of the shaft 55. Therefore, as shown in Figure 5, it is possible to move (slide) the lid 3 toward the front by the amount of this gap.

[0040] (The effect of compact containers) Next, we will describe the case where the compact container 1 configured as described above is used. Firstly, in this compact container 1, as shown in Figure 1, the second engaging projection 46 formed on the lid 3 engages with the first engaging projection 20 formed on the container body 2 from below (undercut fitting), so that the lid 3 can be kept closed relative to the container body 2. This prevents the lid 3 from opening unintentionally during product distribution, storage (when unused), etc.

[0041] When using the compact container 1, as shown in Figure 6, for example, while gripping the container body 2 with the right hand, the lid 3 is pressed forward with the fingertips of the right hand as indicated by arrow F1. This allows the entire lid 3 to slide relative to the container body 2 while elastically deforming the elastic body 60 by the gap between the pivot hole 56 and the shaft 55. As a result, the engaging piece 45 of the lid 3 can be moved forward from the front partition wall 12a of the container body 2.

[0042] As a result, as shown in Figures 5 and 6, the guide surface 26 formed on the front wall 12 can be used to move the engaging piece 45 forward to release the engagement between the first engaging projection 20 and the second engaging projection 46, while also guiding the engaging piece 45 upward. Specifically, the sliding movement of the lid 3 facing forward allows the second engaging projection 46 to move forward together with the engaging piece 45, thereby separating the second engaging projection 46 from the engaging surface 22 of the first engaging projection 20 and releasing the engagement. Furthermore, since the engaging piece 45 can be moved along the guide surface 26, the engaging piece 45 can be pushed upward as the lid 3 faces forward slides.

[0043] Therefore, as shown in Figure 7, the lid 3 can be flipped upward relative to the container body 2 as indicated by arrow F2, and the lid 3 can be opened with a single touch. Furthermore, because the lid 3 is flipped upward, even if the lid 3 returns to its original position backward due to the elastic restoration deformation of the elastic body 60 when the sliding operation of the lid 3, which was facing forward, is released, it is possible to avoid the second engaging projection 46 re-engaging with the first engaging projection 20. Thus, the state in which the lid 3 is flipped upward can be maintained.

[0044] As a result of the above, one-handed operation is possible with a single touch, and the lid can be easily opened with one hand. Therefore, as shown in Figure 8, the lid 3 can be opened using the shaft 55 and the rotating piece 50, and an applicator or the like can be taken out of the storage space S of the container body 2 and used.

[0045] Furthermore, since an elastic body 60 is provided between the rear wall 13 and the rotating piece 50, when the lid 3 is flipped upward, the elastic restoration deformation of the elastic body 60 presses the rotating piece 50 backward, providing resistance to the rotating piece 50. At this time, the elongated rotating hole 56 also rotates along with the rotation of the lid 3, so that the shaft 55 and the rotating hole 56 can come into contact without any gaps. This allows the lid 3 to be used, for example, in a fixed position at any opening angle. In other words, a free-stop function can be achieved.

[0046] As described above, according to this embodiment, the container 1 can be easily opened with one hand, resulting in a user-friendly, compact container 1. Furthermore, since the lid 3 is opened by sliding it forward, there is no need to provide a push piece or the like on the front wall 12 of the container body 2 for opening the lid 3, nor is there a finger grip or the like on the front frame 42 of the lid 3. Therefore, the appearance can be improved, and a simple and aesthetically pleasing compact container 1 can be made.

[0047] Furthermore, since the elastic body 60 is formed in a sheet shape, it can be provided without requiring a large space between the rear wall 13 and the rotating piece 50. Therefore, it can contribute to further miniaturization. Moreover, by utilizing the elastic body 60, the lid 3 can be biased toward the rear even when the lid is in the closed position, so that the first engaging projection 20 and the second engaging projection 46 can be engaged more firmly. This makes it possible to more effectively prevent the lid 3 from opening unintentionally.

[0048] Furthermore, since the engaging piece 45 of the lid 3 can be supported from below by utilizing the support surface 25 of the container body 2, the engagement state between the first engaging projection 20 and the second engaging projection 46 can be maintained more stably. In addition, since the guiding surface 26 is formed so as to be inclined toward the support surface 25, the engaging piece 45 can be guided in a stable state, and the lid 3 can be smoothly flipped upwards.

[0049] When closing the lid 3, the elastic body 60 presses the lid 3 backward, causing the second engaging projection 46 to contact the guide surface 21 of the first engaging projection 20 from above, as shown in Figure 9. Further closing of the lid 3 as indicated by arrow F3 allows the second engaging projection 46 to be pushed downward so as to slide along the guide surface 21. This allows the second engaging projection 46 to be pushed further by closing the lid 3 so as to move over the guide surface 21, and engage with the engaging surface 22 of the first engaging projection 20 from below. Therefore, closing the lid 3 can also be easily performed.

[0050] Although embodiments of the present invention have been described above, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications are possible without departing from the spirit of the invention. Furthermore, modifications in each embodiment may be combined as appropriate. In addition, these embodiments and their modifications include, for example, those that can be easily conceived by a person skilled in the art, those that are substantially the same, and those that are equivalent.

[0051] For example, in the above embodiment, the example of the shaft 55 was described as a cylindrical boss integrally formed on a pair of support pieces 30, but it is not limited to this case. For example, a cylindrical pin formed separately from the support pieces 30 may be used as the shaft, and the support pieces 30 may be combined with the pin.

[0052] Furthermore, in the above embodiment, the example given was a case in which a shaft 55 is provided on the support piece 30 of the container body 2 and a pivot hole 56 is formed in the pivot piece 50 of the lid 3, but the invention is not limited to this case. For example, a shaft 55 may be provided on the pivot piece 50 of the lid 3 and a pivot hole 56 may be formed in the support piece 30 of the container body 2. Even in this case, the lid 3 can be slid forward by utilizing the gap formed between the shaft 55 and the pivot hole 56, so the same effect can be achieved. However, in this case, a gap is formed on the front side of the shaft 55 when the lid 3 is in the closed state. [Explanation of Symbols]

A bottomed cylindrical container body having a circumferential wall including a front wall and a rear wall facing each other in the front-rear direction, and having an internal storage space, The container body is rotatably connected to the container body via a pivot piece positioned behind the rear wall, and comprises a top-shaped cylindrical lid that opens and closes the storage space, The container body has a first engaging projection formed on the front wall and projecting forward, and a support portion formed on the rear wall and facing the rotating piece in the left-right direction, The cover has an engaging piece having a second engaging projection that protrudes rearward and engages with the first engaging projection from below in a manner that allows for detachment. The rotating piece is rotatably connected to the support portion via a shaft extending in the left-right direction, One of the rotating piece and the support member has a rotating hole formed in the shape of an elongated hole that is longer in the front-to-back direction than the diameter of the shaft, through which the shaft body is inserted in the left-to-right direction. The lid is assembled so as to be movable forward relative to the container body by the amount of the gap between the pivot hole and the shaft when the lid is closed relative to the container body. Between the rear wall and the rotating piece, an elastic body is provided that elastically deforms as the lid moves forward. The compact container is characterized in that the front wall has a guiding surface formed thereon that, as the lid moves forward, guides the engaging piece forward to release the engagement between the first engaging projection and the second engaging projection, while simultaneously guiding the engaging piece upward.

2. In the compact container according to claim 1, The elastic body is formed in the form of a sheet made of a softer material than the container body and the lid, and is positioned in a compressed state between the rear wall and the rotating piece when the lid is closed, biasing the lid toward the rear by elastic restoration deformation, in a compact container.

3. In the compact container according to claim 1 or 2, The front wall has a support surface formed therein, which is positioned forward of the first engaging projection and supports the engaging piece from below. The guide surface is integrally formed with the support surface and is inclined to extend upward as it moves forward, in a compact container.
