Description

[Technical field]

[0001] The present invention relates to an application container, in particular an application container for use with cosmetic products such as mascara. [Background technology]

[0002] For example, a known applicator container for storing cosmetics and the like comprises a container body with a neck portion standing from a body portion, a tubular striking member fixed to the inner surface of the neck portion, a cylindrical cap body with a top fitted to the outer surface of the neck portion, and an applicator attached to the lower end of an axial rod that hangs down from the top plate side of the cap body, through the inside of the striking member, and into the container body (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-138446 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, when it is necessary to use an opaque container with light-blocking properties to preserve the contents, there is a problem in that it is not possible to know the remaining amount of the contents and therefore not possible to know when to purchase a new container.

[0005] According to the present invention, in an application container having a light-shielding property as a whole, it is possible to make it possible to visually check the remaining amount of the content from the outside. Also, it is possible to easily realize the checking operation. [Means for solving the problem]

[0006] The first means comprises an inner container 20 having a neck portion 32 extending from a body portion 24 and having translucency; A cylindrical covering body 4 having light-shielding properties surrounding at least the peripheral surface of the inner container 20; and a cap 40 with an applicator, in which a cap body 42 is attached to the cover body 4 so as to be movable up and down, and a vertically long applicator 56 is suspended from inside the cap body 42 through the mouth and neck portion 32. The device is provided with an interlocking mechanism L which, in conjunction with the cap body 42, raises and lowers the inner container 20 relative to the covering body 4 in the opposite direction to the raising and lowering of the cap body 42, so that the lower portion 20a of the inner container 20 is exposed when viewed from the side during the opening operation of the cap body 42.

[0007] In this means, as shown in FIG. 1, the peripheral surface of a light-transmitting inner container is surrounded by a light-blocking cylindrical covering body 4, and a cap body 42 is attached to this covering body 4 so as to be movable up and down. 2, an interlocking mechanism L is provided which moves the cap body 42 up and down in the opposite direction to the up and down movement of the cap body 42. Due to the action of this interlocking mechanism L, the lower portion 20a of the inner container 20 is exposed when viewed from the side during the opening operation of the cap body 42. According to this structure, the remaining amount of the contents can be reliably visually confirmed through the exposed area from the side (gap G shown in FIG. 2).

[0008] the second means includes the first means, and the interlocking mechanism L screws the cap body 42 to the covering body 4 via a first screw portion n1 and screws the covering body 4 to the inner container 20 via a second screw portion n2, forming the first screw portion n1 and the second screw portion n2 as reverse screws, and forming a co-rotating means m between the cap body 42 and the inner container 20 for rotating the inner container 20 in the same direction as the cap body 42; Due to the action of the interlocking mechanism L, during the course of the operation of unscrewing the cap body 42, the lower part 20a of the inner container 20 is positioned below the cap body 42, and the lower part 20a is exposed when viewed from the side.

[0009] In this means, as shown in FIG. 1, the interlocking mechanism L is configured such that the cap body 42 is screwed to the covering body 4 via a first screw portion n1 and the covering body 4 is screwed to the inner container 20 via a second screw portion n2, the first screw portion n1 and the second screw portion n2 are formed as reverse threads, and a co-rotating means m is formed between the cap body 42 and the inner container 20 for rotating the inner container 20 in the same direction as the cap body 42. And, by the action of this interlocking mechanism L, during the course of the operation of unscrewing the cap body 42, the lower part 20a of the inner container 20 is positioned below the cap body 42, as shown in FIG. 2, so that the lower part 20a is exposed when viewed from the side. According to this structure, the exposed area G of the inner container 20 can be easily formed by unscrewing the cap body 42, so that the remaining amount of contents can be easily and visually confirmed, and the visual confirmation operation can be performed reliably by utilizing the screw means.

[0010] The third means comprises an outer container 2 having the first means or the second means, and a bottom member 14 for covering the lower surface of the inner container 20 attached detachably to the lower end of the covering body 4, and is formed so that when the cap body 42 is opened, the covering body 4 and the bottom member 14 are separated, and the inner container 20 is exposed from the gap G between the covering body 4 and the bottom member 14.

[0011] As shown in Fig. 1, this means includes an outer container 2 having a bottom member 14 detachably attached to the lower end of the covering body 4 to cover the lower surface of the inner container 20. When the cap body 42 is opened, the covering body 4 and the bottom member 14 are separated as shown in Fig. 2, and the inner container 20 is exposed from a gap G between the covering body 4 and the bottom member 14. According to this structure, the remaining amount of the contents can be visually confirmed from all directions in the radial direction of the cover 4 through the gap G, facilitating visual confirmation work.

[0012] The fourth means has the first means or the second means, and forms a pressure-welded portion 8 that prevents the inner container 20 from falling off from within the covering body 4 by pressing one surface of the inner surface of the covering body 4 or the outer surface of the inner container 20 against the other surface.

[0013] In this means, as shown in FIG. 1, a vertical protrusion 8 is formed on one of the inner surfaces of the covering body 4 or the outer surface of the inner container 20, which is pressed against the other surface, thereby forming a pressure-contact portion 8 that prevents the inner container 20 from falling off from within the covering body 4. According to this structure, the range in which the inside of the inner container 20 can be viewed from the side (the above-mentioned exposed range G) is not narrowed due to the falling off of the cover 4, and the viewing operation can be performed accurately. Effect of the Invention

[0014] According to the present invention, in an application container having a light-shielding body, the remaining amount of the content can be visually confirmed from the outside. Furthermore, the confirmation operation can be easily realized. [Brief description of the drawings]

[Diagram 3] 3A and 3B are partial views of the configuration shown in FIG. 2, in which FIG. 3A shows the structure of the portion indicated by the symbol III(A), and FIG. 3B shows the structure as viewed in the III(B)-III(B) direction. [Figure 4] FIG. 2 is an explanatory diagram of an assembly operation for the container shown in FIG. BEST MODE FOR CARRYING OUT THEINVENTION

[0016] 1 to 4 show an applicator container according to an embodiment of the present invention. This applicator container comprises a container portion 1 and an applicator-equipped cap 40. Each of these members can be formed of, for example, a synthetic resin material.

[0017] 1, the container part 1 in this embodiment is composed of an outer container 2, an inner container 20, and a filtering member 36. However, this structure can be modified as appropriate.

[0018] The outer container 2 is a light-shielding cylindrical container with a bottom. The outer container 2 of this embodiment is configured by removably attaching a bottom member 14 to the lower surface of a vertically long cover body 4, and the cover body 4 and the bottom member 14 are each made of a light-shielding material. The covering body 4 is a member that surrounds the periphery of the inner container 20, and in the illustrated example, is approximately cylindrical overall, with a short, small outer diameter cylindrical portion 4b standing upright from a long, large outer diameter cylindrical portion 4a via an upward step portion 6. A first male thread 10, which is a forward thread, is formed on the outer surface of the small outer diameter cylindrical portion 4b, and a second female thread 12, which is a reverse thread, is formed on the inner surface portion extending from the small outer diameter cylindrical portion 4b to the upper part of the large outer diameter cylindrical portion 4a. A vertical ridge 8 is provided on the inner surface of the large outer diameter cylindrical portion 4a as a pressure contact portion that is pressure-contacted with a body portion 24 of an inner container 20 described below. This pressure contact prevents the inner container 20 from falling out of the covering body 4 when the inner container 20 is completely unscrewed from the covering body 4, as shown in Fig. 2. The structure of the pressure contact portion is not limited to the vertical ridge, and any structure may be used as long as it can prevent the inner container 20 from falling out. 2, the upper side surface of the vertical protrusion 8 is formed so as to abut against a lower end portion 28a of a second male screw 28 (described later) when the inner container 20 is screwed down into the covering body 4. This abutment defines the lowest limit position for screwing down. The bottom member 14 has an annular joining ring 18 standing on the upper surface of the outer periphery of the disk-shaped outer bottom plate 16. The lower end of the cover 4 is in detachable contact with or close to the outer surface of this joining ring, and the inner surface of the joining ring 18 is non-detachably engaged with a ring receiving portion 26 of the inner container 20, which will be described later. This engagement prevents the bottom member 14 from falling off the inner container 20 when it is lowered relative to the cover 4, as shown in Figure 2. The structure of the joining ring 18 can be modified as appropriate as long as it functions as a joining part for the covering body 4 and the inner container 20. In the illustrated example, a single ring-shaped member serves both as a joining part for the covering body 4 and as a joining part for the inner container 20, but separate joining parts may be provided. In addition, the joining part does not need to be ring-shaped, and may be a joining rib that joins the covering body 4 and the inner container 20 at appropriate circumferential positions.

[0019] The inner container 20 is a light-transmitting content storage container, and in this embodiment, is formed in a cylindrical shape with a bottom that is longer than the outer container 2 . The inner container 20 can be made transparent or translucent. In the illustrated example, the inner container 20 has a body 24 extending upward from the peripheral edge of the inner bottom plate 22, and a neck opening 32 stands upright from the body 24 via a generally tapered shoulder 30. The body 24 is approximately the same height as the covering body 4, and the neck opening 32 is located above the covering body 4. However, the length and location of these parts can be changed as appropriate. The inner bottom plate 22 is formed to be thicker than the body portion 24, and a groove-shaped ring receiving portion 26 into which the joining ring 18 fits is formed on the outer circumferential surface of the inner container 20, located to the side of the inner bottom plate 22. The shape of the ring receiving portion 26 may be any shape as long as it is capable of holding the joining ring 18. In the illustrated example, when the ring receiving portion 26 is engaged with the joining ring 18, the inner bottom plate 22 is adjacent to the outer bottom plate 16, but it does not matter if they are in contact with each other.

[0020] An appropriate number (a pair in the illustrated example) of first torque transmitting engagement ribs 34 are formed over the entire cylindrical length on the outer surface of the mouth neck portion 32. However, the length and number of the first torque transmitting engagement ribs 34 can be changed as appropriate. The first torque transmitting engagement rib 34 plays a role in transmitting a rotational force from the cap body 42 to the inner container 20 by engaging (contacting in the circumferential direction) with a second torque transmitting engagement rib 52 formed on the inner surface of the guide tube portion 50 described later. The structure of the second torque transmitting engagement rib 52 will be described later. In this embodiment, the first torque transmitting engagement thread 34 and the second torque transmitting engagement thread 52 form a co-rotation means m between the cap body 42 and the inner container 20 for rotating the inner container 20 in the same direction as the cap body 42. The main function of the co-rotation means m is to restrict the relative rotation of the inner container with respect to the cap body 42 (rotation prevention). As long as this function is ensured, the co-rotation means m may have any structure.

[0021] A reverse thread (second male thread 28) that meshes with the second female thread 12 is formed on the upper end of the outer surface of the body 24, and these second male threads 28 and second female threads 12 form a second screw portion n2 for screwing the inner container 20 up and down relative to the covering body 4. As described above, the first thread portion n1 and the second thread portion n2 are formed as reverse threads. In this specification, the expression "forming the first thread portion and the second thread portion as reverse threads" includes an embodiment in which the second thread portion n2 is formed as a forward thread and the first thread portion n1 is formed as a reverse thread. Then, as the inner container 20 is screwed down relative to the covering body 4, the lower end of the covering body 4 is detached from the joining ring 18, and a gap G is formed between the lower end of the covering body 4 and the bottom member 14, as shown in Fig. 2. This causes the translucent lower part 20a of the inner container 20, shown in Fig. 4, to be exposed to the outside. Therefore, the user can visually check the remaining amount of the contents through the gap. Next, the inner container 20 is screwed upward relative to the covering body 4, thereby closing the gap G and fitting the lower end of the covering body 4 into the joining ring 18. The range in which the second male thread 28 is formed (the upper and lower ranges of the outer circumferential surface of the body portion 24) should be designed so as to ensure a sufficient gap G required for checking the remaining amount. As the inner container 20 is screwed up relative to the cover 4, the second male screw 28 provided on the inner container 20 descends from the height shown in FIG. 1 relative to the cover 4, and abuts against the upper end of the vertical protrusion 8 from one side in the circumferential direction at the lowest screw-down position shown in FIG. 2. The height of the upper end of the vertical protrusion 8 is designed so that the abutment occurs when the first female screw 48 of the cap body 42 described below is unscrewed from the first male screw 10 of the cover 4, as shown in FIG. 2. This allows the user to recognize that the lowest position of the screw operation has been reached by the tactile sensation of the abutment. Therefore, by pulling up the cap body 42 from this state, the shaft 58 of the applicator 56 described below can be pulled out from the inner container 20. The structure of the present embodiment described above can be modified as appropriate. For example, instead of screwing the inner container and cap body 42 up and down relative to the cover body 4, the structure may simply be such that the inner container and cap body 42 move linearly up and down. Furthermore, the mechanism for screwing the inner container 20 and the cap body 42 up and down relative to the covering body 4 does not have to be a screw portion, but may be, for example, a spiral groove formed on the inner and outer surfaces of the covering body 4 and a sliding contact protrusion attached to the inner container 20 and the cap body 42 so as to slide within this spiral groove.

[0022] The striking member 36 is fitted into the inner surface of the mouth and neck portion 32. The striking member 36 in the illustrated example is integrally formed from the same material (elastic material) as a whole, and a flange portion 37 attached to the upper end portion of the cylindrical wall fitted into the mouth and neck portion 32 is engaged with the upper end surface of the mouth and neck portion 32, and a tapered striking portion 38 is provided to protrude downward and inward from the longitudinal middle portion of the cylindrical wall. As shown in Fig. 3(A), an annular sealing ridge i is provided around the upper surface of the flange 37 for elastically pressing against a head 64 of an applicator 56, which will be described later. This allows the mouth and neck portion 32 of the inner container 20 to be tightly sealed in the closed state shown in Fig. 1. However, these structures can be modified as appropriate.

[0023] As shown in FIG. 1, the cap with applicator 40 comprises a cap body 42 and an applicator 56. Specifically, the cap body 42 is attached to the cover body 4 so as to be movable up and down, and the vertically long applicator 56 is suspended from inside the cap body 42, via the mouth / neck portion 32. In the illustrated example, a head portion 64 of an applicator 56 is connected to the inside of a cylindrical cap body 42 so as to be movable up and down. However, the structure can be modified as appropriate, and the cap body 42 and the applicator 56 may be connected integrally.

[0024] The cap body 42 is screwed onto the cover body 4 so as to be capable of being screwed up and down between a lower limit position P1 shown in FIG. 1 and an upper limit position P2 shown in FIG. In the illustrated example, the cap body 42 has an outer peripheral wall 46 extending from the peripheral end of the top plate 44 and a guide tube portion 50 extending concentrically downward from the underside of the top plate 44 for guiding the raising and lowering of an applicator 56 . In the illustrated example, the outer peripheral wall 46 is vertically extended from the top plate 44 to the vicinity of the upward step portion 6 of the covering body 4. A first female thread 48 (forward thread) that meshes with the first male thread 10 is provided at the lower end of the outer peripheral wall 46. The first male thread 10 and the first female thread 48 form a first screw portion n1. In the illustrated example, the guide tube portion 50 is shorter than the outer peripheral wall 46 and extends to the vicinity of the shoulder portion 30 so as to surround the mouth and neck portion 32 . Further, on the inner surface of the guide tube portion 50, a second torque transmitting engaging thread 52 that abuts against the first torque transmitting engaging thread 34 is vertically provided. In this specification, the term "engagement strip" includes both convex and concave stripes. In the illustrated example, one convex torque transmitting first engagement thread 34 is provided with two convex torque transmitting second engagement threads 52 that sandwich the engagement thread from both sides. However, one of the torque transmitting first engagement thread 34 and the torque transmitting second engagement thread 52 may be formed as an engagement convex thread, and the other may be formed as an engagement concave thread that meshes with the engagement convex thread.

[0025] A plurality of projection receiving portions 54 for engaging with locking projections 66 of a head portion 64 described below are disposed at appropriate positions on the inner surface of the guide tube portion 50 (between the two second engagement threads 52 for torque transmission in the illustrated example). By engaging the locking protrusions 66 with these protrusion receiving portions 54, when the applicator cap 40 is removed from the container portion 1, as shown in Figure 4, the head portion 64 of the applicator 56 is connected inside the cap body 42, and is arranged to support the applicator 56 hanging down from the cap body 42. It is desirable that the locking projections 66 and the projection receiving portions 54 are disposed equiangularly in the circumferential direction of the head portion 64 and the guide tube portion 50 . The height of the projection receiving portion 54 is designed so as to engage the locking projection 66 when the cap body 42 is at the upper limit position P2 shown in FIG. 3(A), the structure of the projection receiving portion 54 in this embodiment employs a pair of upper and lower projections (upper projection 54a and lower projection 54b) that sandwich the locking projection 66 from above and below in the locked state. This prevents the applicator 56 from rattling in the vertical direction relative to the cap body 42. The upper protrusion 54 a and the lower protrusion 54 b in the illustrated example are provided to gently protrude inward from the inner surface of the guide tube portion 50 . The upper protrusion 54a is formed so that the cap body 42 can easily get over the locking projection 66 when the cap body 42 is screwed up and down between the upper limit position P2 and the lower limit position P1 shown in Fig. 1 relative to the cover body 4. These structures can be modified as appropriate.

[0026] In this embodiment, the applicator 56 is formed of a head portion 64, a shaft rod 58, and an applicator portion 68, as shown in FIG. The head portion 64 is held so as to be vertically movable within the guide tube portion 50. Due to this holding, the applicator 56 is linked to the inside of the cap body 42 and hangs down from the cap body 42, as shown in FIG. In addition, the head portion 64 is placed on the flange portion 37 in the initial state shown in FIG. The head portion 64 in the illustrated example is composed of a bottom portion 64a that is integrally connected to the shaft rod 58, a corner portion 64b that spreads outwardly upward from the peripheral end of the bottom portion 64a, and a straight cylindrical head tube portion 64c that extends upward from the upper end of the corner portion 64b, and is formed as a hollow cylindrical structure with a bottom as a whole. However, the structure of the head portion 64 can be modified as appropriate. An appropriate number of locking projections 66 (a pair in the illustrated example) are provided on the outer circumferential surface of the head portion 64, and these projections are locked to the projection receiving portion 54 in the state shown in Fig. 2, thereby preventing the head portion 64 from rattling in the vertical direction. The locking projection 66 in the illustrated example is formed in a narrow trapezoid shape at the tip portion 66a side as shown in Fig. 3(A) when viewed from the side, and the tip portion 66a is formed so as to be sandwiched between the upper projection 54a and the lower projection 54b of the projection receiving portion 54. In the illustrated example, the tip portion 66a abuts against the inner surface of the guide tube portion 50. However, the structure and shape of the locking projection 66 can be appropriately changed. The shaft rod 58 is elongated, and a ring-shaped groove 62 is provided around the middle of the shaft rod 58 in the vertical direction to accommodate the tip end (inner end) of the striking portion 38 when the cap body 42 is in the upper limit position P2 shown in FIG. 2. Further, the shaft rod 58 is formed with an annular sliding portion 60 located above the annular groove 62 and in sliding contact with the inner peripheral surface of the guide tube portion 50. Therefore, the sliding contact allows the vertical movement of the shaft rod 58 to be stably guided within the guide tube portion 50. The shaft 58 contacts the entire inner surface of the striking member 36 fitted into the neck portion 32 via the annular sliding portion 60, while the head portion 64 only contacts locally at a number of points in the circumferential direction of the inner surface of the guide tube portion 50 via a number of locking projections 66. Therefore, when the cap body 42 is unscrewed from the neck portion 32 of the inner container 20, the frictional force acting between the applicator 56 and the inner container 20 is greater than the frictional force acting between the applicator 56 and the cap body 42, and the applicator 56 remains in the original position shown in FIG. 2, as described above, the locking projection 66 is locked to the projection receiving portion 54, and when the cap body 42 is lifted from this state, the applicator 56 rises together with the cap body 42 and is pulled out from the inner container 20. During this removal, the applicator part 68 passes through the rubbing portion 38, so that the applicator part 68 is rubbed, and is pulled up with an appropriate amount of the contents remaining attached to the applicator part 68.

[0027] In this embodiment, a forward thread (first thread portion n1) formed between the covering body 4 and the cap body 42, a reverse thread (second thread portion n2) formed between the covering body 4 and the inner container 20, and a co-rotating means m formed between the cap body 42 and the inner container 20 form an interlocking mechanism L that regulates the vertical movement of the inner container 20 relative to the cap body 42. The role of this interlocking mechanism L is to move the inner container 20 up and down relative to the cover body 4 in the direction opposite to the up and down movement of the cap body 42 in conjunction with the cap body 42 . "Raising and lowering in the opposite direction to the rising and lowering of the cap body 42" means that when the cap body 42 rises, the inner container 20 descends, and when the cap body 42 descends, the inner container 20 rises. Due to the action of this interlocking mechanism, during the course of unscrewing the cap body 42, the lower part 20a of the inner container 20 is positioned below the cap body 42, as shown in Fig. 2. Therefore, in this state, the lower part 20a of the inner container 20 is exposed when viewed from the side. Here, since the inner container 20 is lowered and raised in conjunction with the opening and closing of the cap body 42, the remaining amount of the inner container 20 can be checked at least every time application work is performed, and the frequency of checking the remaining amount can be increased. Therefore, the remaining amount can be adequately determined before replacing the product, and the inconvenience of running out of the remaining amount while using the product, as in the conventional technology, can be avoided. Furthermore, since no special effort or operation is required for the confirmation and the operation procedure is the same as that for conventional application containers, the confirmation work can be easily performed.

[0028] In the above configuration, when checking the remaining amount of contents, from the state shown in Fig. 1, the cover 4 is held with one hand and the cap body 42 is rotated in the opening direction with the other hand. Then, the rotational force (torque) on the cap body 42 is transmitted to the inner container 20 via the co-rotating means m. Since the first screw portion n1 and the second screw portion n2 are formed as reverse threads, the cap body 42 screws up relative to the cover 4, while the inner container 20 screws down. With this configuration, a gap G is generated between the covering body 4 and the bottom member 14 attached to the inner container 20, as shown in FIG. Therefore, the remaining amount in the inner container 20 can be visually confirmed through this gap G. Since the gap G is formed all around the circumference of the covering body 4, visual confirmation can be performed from any horizontal direction. When performing the application operation following the visual inspection operation, after the cap body 42 has been completely unscrewed from the covering body 4, as shown in FIG. 2, the cap body 42 is further pulled up and the shaft 58 of the applicator 56 is pulled out from the mouth / neck portion 32. After the application work is completed, the application part 68 and the shaft 58 of the applicator 56 are inserted into the inner container 20 as shown by the dotted line in FIG. When no coating operation is to be performed, the cap body 42 may be rotated in the closing direction from the state shown in FIG.

[0029] According to the above-mentioned configuration and operation, the interlocking mechanism L is provided for raising and lowering the cover 4 surrounding the translucent inner container 20 in the opposite direction to the raising and lowering of the cap body 42 screwed onto the mouth and neck of the inner container 20, so that the lower part 20a of the inner container 20 is exposed when viewed from the side during the process of opening the cap body 42, allowing the remaining amount of contents to be visually confirmed. In addition, the interlocking mechanism L utilizes a screw means, so that the lower part 20a of the inner container 20 can be reliably exposed. The bottom member 14 separates from the covering body 4 of the outer container 2, and the remaining amount of the contents can be visually confirmed from all radial directions of the covering body 4 through the gap G, facilitating visual confirmation work. Since the inner surface of the covering body 4 is formed with vertical ridges 8 which are pressed against the outer surface of the inner container 20, the inner container 20 will not fall out from inside the covering body 4 even when it is completely unscrewed from the covering body 4.
