Description

The present invention relates to a container with a lid.

A container with a lid, such as that described in Patent Document 1 below, has been known in the past. This container with a lid is a so-called dispensing container. This container with a lid includes a container body that contains the contents, and a lid body that is removably attached to the container body.

Patent No. 4324936

In the meantime, a configuration using a magnet is known for this type of container with lid. In this configuration, the container with lid further includes a first magnet provided on the container body, and an attraction member provided on the lid, facing the first magnet in the container axial direction and attracted to the first magnet. In this container with lid, the attraction member is attracted to the first magnet, thereby maintaining the lid attached to the container body.
However, in the case of the above-mentioned lidded container, when the lid is detached from the container body and the lid is attached to the container body, there is a risk that the lid will collide with the container body due to the attractive force of the first magnet against the suction member, resulting in a loud noise.

The present invention was made in consideration of the above-mentioned circumstances, and aims to reduce the impact that occurs between the lid and the container body when the lid is attached to the container body.

<1> A lidded container according to one embodiment of the present invention comprises a container body for accommodating contents, a lid body removably attached to the container body, a first magnet provided on either the container body or the lid body, and an attraction member provided on the other of the container body or the lid body, facing the first magnet in the container axial direction and attracted to the first magnet, wherein the container body is provided with an annular receiving surface facing the lower end surface of the lid body, and an annular protrusion provided radially inward from the receiving surface, protruding upward from the receiving surface, and covered from the radial outside by the lower end of the lid body, and a rib is provided on the inner surface of the lower end of the lid body so as to be slidable along the outer circumferential surface of the protrusion in the container axial direction , and the rib is located below the first magnet or the attraction member provided on the lid body .

The rib can slide on the outer peripheral surface of the protrusion in the container axial direction. Therefore, when the protrusion of the container body is placed inside the lower end of the lid in order to attach the lid to the container body while the lid is detached from the container body, the rib slides on the outer peripheral surface of the protrusion in the container axial direction. Therefore, when the suction member is attracted to the first magnet, the speed at which the lid moves relative to the container body can be reduced. As a result, the impact generated when the lid comes into contact with the container body can be mitigated, and the generated sound can be kept small. This can ensure, for example, a luxurious feel for the lidded container.
Furthermore, the rib is provided on the inner peripheral surface of the lower end of the lid, not on the outer peripheral surface of the protrusion. This makes it possible to make the rib less visible from the outside. As a result, the appearance of the lidded container can be improved. This can, for example, further ensure the luxurious feel of the lidded container.

<2> A lidded container according to one embodiment of the present invention comprises a container body for accommodating contents, a lid body removably attached to the container body, a first magnet provided on either the container body or the lid body, and an attraction member provided on the other of the container body or the lid body, facing the first magnet in the container axial direction and attracted to the first magnet, wherein the container body is provided with an annular receiving surface facing the lower end surface of the lid body, and an annular protrusion provided radially inward from the receiving surface, protruding upward from the receiving surface, and covered from the radial outside by the lower end of the lid body, and a rib is provided on the inner peripheral surface of the lower end of the lid body so as to be able to slide on the outer peripheral surface of the protrusion in the container axial direction, the rib is a vertical rib extending in the container axial direction, the radial size of the lower end of the rib gradually decreases as it extends downward, and in a vertical cross-sectional view of the rib, the lower edge of the rib is curved so as to protrude radially inward.

In a vertical cross-sectional view of the rib, the lower edge of the rib is curved and protrudes radially inward. Therefore, for example, in a vertical cross-sectional view of the rib, the area of the rib itself that comes into contact with the container body can be made smaller than when the lower edge of the rib is a straight line extending radially. As a result, the impact described above can be more effectively mitigated.

<3> In the lidded container according to <1> or <2> above, in a plan view of the container body, the outer peripheral surface of the protrusion is rectangular with four first corners and four first sides, and either the first magnet or the suction member is disposed at a position corresponding to the first corners, and in a plan view of the lid, the inner peripheral surface of the lower end of the lid is rectangular with four second corners and four second sides, and either the first magnet or the suction member is disposed at a position corresponding to the second corners, and the ribs may be provided on at least two of the four second sides.

Either the first magnet or the suction member is disposed at a position corresponding to the first corner. And the other of the first magnet or the suction member is disposed at a position corresponding to the second corner. And ribs are provided on at least two of the four second sides. Therefore, in a plan view of the lidded container, the positions of the first magnet and the suction member can be made different from the positions of the ribs. This allows the ribs to slide effectively on the outer peripheral surface of the protrusion.

<4> In the lidded container according to any one of <1> to <3> above, the suction member may be a second magnet that is mutually attracted to the first magnet.

The attraction member is a second magnet that attracts the first magnet to each other. In other words, the attraction member is not a magnetic material (such as some metals such as iron) that is simply attracted to the first magnet. Therefore, the first magnet and the second magnet are strongly attracted to each other, and the lid is firmly attached to the container body. In addition, when the second magnet as the attraction member is attracted to the first magnet, the first magnet is also attracted to the second magnet, making it easier to increase the speed at which the lid moves relative to the container body. Therefore, the effect of the rib reducing the movement speed of the lid is significantly effective.

The present invention can reduce the impact that occurs between the lid and the container body when the lid is attached to the container body.

1 is a vertical cross-sectional view of a container with a lid according to one embodiment of the present invention. 2 is a plan view of the container shown in FIG. 1 , in which a lid is indicated by a two-dot chain line. FIG. 3 is a cross-sectional view taken along the line III-III in FIG. 2. 4 is a cross-sectional view taken along the line IV-IV in FIG. 2.

Hereinafter, a container with lid 10 according to one embodiment of the present invention will be described with reference to FIGS.
In this embodiment, the container with lid 10 is a so-called dispensing container. The dispensing container contains, for example, a stick-shaped content such as a cosmetic (such as lipstick, lip balm, or stick eye shadow), a medicine, or a glue. However, the container with lid 10 does not have to be a dispensing container, and may be, for example, a jar container or a compact container.

As shown in FIGS. 1 to 4 , the container with lid 10 includes a container body 20 and a lid body 40 .
The container body 20 accommodates the contents. The lid body 40 is removably attached to the container body 20. The lid body 40 covers the contents.
Here, the central axes of the container body 20 and the lid body 40 are located on a common axis. Hereinafter, the common axis is referred to as the container axis O, the lid body side along the container axis O direction is referred to as the upper side (one side), and the container body side along the container axis O direction is referred to as the lower side (the other side). The direction perpendicular to the container axis O is referred to as the radial direction, and the direction going around the container axis O is referred to as the circumferential direction.

The container body 20 comprises a main body tube 21, a storage tube 22, a decorative tube 23, a sliding ring 24, a middle plate 25, and a first magnet 26.

The main body tube 21 is a bottomed tube. The main body tube 21 is a double tube. The main body tube 21 includes a first outer tube 27 and a first inner tube 28. The first outer tube 27 is a bottomed tube. The first inner tube 28 is disposed within the first outer tube 27. The first inner tube 28 is a tube that opens on both sides in the direction of the container axis O. The rotation of the first inner tube 28 relative to the first outer tube 27 is restricted, for example, by the two engaging with each other. The first inner tube 28 rotates in conjunction with the circumferential rotation of the first outer tube 27. The up and down movement of the first inner tube 28 relative to the first outer tube 27 is restricted, for example, by the two engaging with each other.

The storage tube 22 stores the contents. The storage tube 22 extends upward from the main body tube 21. The lower end of the storage tube 22 is disposed within the main body tube 21. The upper end of the storage tube 22 is located above the main body tube 21. Rotation of the storage tube 22 relative to the main body tube 21 is regulated, for example, by the two engaging with each other. The storage tube 22 rotates in conjunction with the circumferential rotation of the main body tube 21. Up and down movement of the storage tube 22 relative to the main body tube 21 is regulated, for example, by the two engaging with each other.

The decorative tube 23 covers the main tube 21 from the outside in the radial direction. The lower end of the decorative tube 23 is sandwiched between the lower end of the storage tube 22 and the main tube 21. The upper end of the decorative tube 23 covers the upper end of the storage tube 22 from the outside in the radial direction. The decorative tube 23 is double-tubular. Rotation of the decorative tube 23 relative to the main tube 21 and the storage tube 22 is not restricted. The decorative tube 23 is rotatable in the circumferential direction relative to the main tube 21 and the storage tube 22.

The sliding ring 24 prevents the housing tube 22 and the decorative tube 23 from rattling relative to each other. The sliding ring 24 is disposed between the lower end of the housing tube 22 and the lower end of the decorative tube 23. Rotation of the sliding ring 24 relative to the housing tube 22 is restricted, for example, by the two engaging with each other. On the other hand, rotation of the sliding ring 24 relative to the decorative tube 23 is not restricted. When the main tube 21 and the housing tube 22 rotate, the sliding ring 24 rotates while sliding on the inner circumferential surface of the decorative tube 23.

The inner plate 25 holds the contents. The inner plate 25 is housed in the storage tube 22. As the storage tube 22 and the decorative tube 23 rotate relative to each other, the inner plate 25 moves up and down inside the storage tube 22. The configuration for achieving this movement can be realized by a configuration used in known dispensing containers (for example, a configuration including a protrusion, a vertical groove, or a spiral groove, or a configuration including a screw shaft and in which the inner plate is screwed onto the screw shaft, etc.).

As shown in FIG. 3, in the container body 20, a first circumferential groove 29 is provided at the upper end of the first outer tube 27 of the main body tube 21. The first circumferential groove 29 opens radially inward and also opens upward. Furthermore, a first flange 30 is provided at the upper end of the first inner tube 28 of the main body tube 21. The first flange 30 is located below the upper end surface of the first inner tube 28. The first flange 30 is disposed in the first circumferential groove 29. The lower surface of the first flange 30 is supported by the lower surface of the first circumferential groove 29. The upper surface of the first flange 30 is flush with the upper end surface of the first outer tube 27.

The container body 20 is provided with an annular receiving surface 31 and an annular protrusion 32. The receiving surface 31 and the protrusion 32 are both provided on the main body tube 21.
The receiving surface 31 faces the lower end surface 40b of the lid body 40. The receiving surface 31 may be in contact with or separated from the lower end surface 40b of the lid body 40. The receiving surface 31 is formed by the upper end surface of the first outer cylinder 27 and the upper end surface of the first flange 30.
The protrusion 32 is provided on the radially inner side of the receiving surface 31. The protrusion 32 protrudes upward from the receiving surface 31. The receiving surface 31 is formed by a portion of the first inner tube 28 that is located above the first flange 30.

As shown in FIG. 2, in a plan view of the container body 20, the outer peripheral surface of the protrusion 32 is rectangular (hereinafter referred to as a first rectangular shape 33). The first rectangular shape 33 has four first corners 34 and four first sides 35. In addition, in the plan view, the inner peripheral surface of the storage tube 22 is circular.

The first magnet 26 is disposed at a position corresponding to the first corner 34. Here, the position corresponding to the first corner 34 is a position on a virtual straight line (hereinafter referred to as the first straight line L1) that passes through the container axis O and the first corner 34 in the plan view. The first magnet 26 is located on the first straight line L1.

As shown in FIG. 4, the first magnet 26 is attached to the first inner cylinder 28. The first inner cylinder 28 is provided with a first recess 36. The first recess 36 is recessed upward. The first recess 36 opens downward. The first magnet 26 is fitted into the first recess 36. The first magnet 26 is provided in the protrusion 32. In this embodiment, the upper end of the first magnet 26 is disposed within the protrusion 32. In other words, a portion of the protrusion 32 is formed by the first magnet 26.

As shown in FIG. 1, the lid body 40 is removably attached to the container body 20. The lid body 40 is cylindrical with a top. The lid body 40 is double cylindrical. The lid body 40 includes a second outer cylinder 41, a second inner cylinder 42, and a second magnet 43 (attraction member). The second outer cylinder 41 and the second inner cylinder 42 are cylindrical with a top.

The second inner cylinder 42 is disposed within the second outer cylinder 41. Rotation of the second inner cylinder 42 relative to the second outer cylinder 41 is restricted. The second inner cylinder 42 rotates in conjunction with the circumferential rotation of the second outer cylinder 41. Up-down movement of the second inner cylinder 42 relative to the second outer cylinder 41 is restricted.
Note that a known configuration may be appropriately adopted as a configuration for restricting the rotation of the second inner cylinder 42 relative to the second outer cylinder 41. Also, a known configuration may be appropriately adopted as a configuration for restricting the up and down movement of the second inner cylinder 42 relative to the second outer cylinder 41.

As shown in FIG. 3, the cover 40 has a second circumferential groove 44 at the lower end of the second outer tube 41. The second circumferential groove 44 opens radially inward and downward. Furthermore, an expanded diameter portion 45 and a second flange 46 are provided at the lower end of the second inner tube 42 of the cover 40. The expanded diameter portion 45 has a larger diameter than the portion of the second inner tube 42 located above the expanded diameter portion 45. The expanded diameter portion 45 is located at the lower end of the second inner tube 42. The second flange 46 is located at the lower end of the expanded diameter portion 45. The lower surface of the second flange 46 is flush with the lower end surface of the expanded diameter portion 45. The second flange 46 is disposed in the second circumferential groove 44. The lower surface of the second flange 46 is flush with the lower end surface of the second outer tube 41.

The inner diameter of the lower end 40a of the lid 40 is larger than the inner diameter of the portion of the lid 40 located above the lower end. The lower end 40a of the lid 40 is formed by the lower end of the second outer tube 41 and the lower end (expanded diameter portion 45) of the second inner tube 42. The inner peripheral surface of the lower end 40a of the lid 40 is formed by the expanded diameter portion 45. The lower end surface 40b of the lid 40 is formed by the lower end surface of the expanded diameter portion 45, the lower surface of the second flange 46, and the lower end surface of the second outer tube 41.

The lower end 40a of the lid 40 covers the protrusion 32 from the outside in the radial direction. The inner circumferential surface of the lower end 40a of the lid 40 is connected via a step 50 to the inner circumferential surface of a portion of the lid 40 that is located above the lower end. The step 50 and the upper end surface of the protrusion 32 face each other in the direction of the container axis O. The step 50 and the upper end surface of the protrusion 32 may be in contact or may be separated.

As shown in FIG. 2, in a plan view of the lid body 40, the inner peripheral surface of the lower end portion 40a of the lid body 40 is rectangular (hereinafter referred to as the second rectangular shape 47). The second rectangular shape 47 is similar to the first rectangular shape 33. The second rectangular shape 47 is larger than the first rectangular shape 33. The second rectangular shape 47 has four second corners 48 and four second sides 49.

2 and 4, the second magnet 43 faces the first magnet 26 in the direction of the container axis O. The second magnet 43 is disposed above the step 50. The second magnet 43 functions as an attraction member that is attracted to the first magnet 26. However, unlike a simple magnetic body (e.g., some metals such as iron), the second magnet 43 and the first magnet 26 are attracted to each other.
In this embodiment, the second magnet 43 is disposed at a position corresponding to the second corner 48. Here, the position corresponding to the second corner 48 is a position on a virtual straight line (hereinafter referred to as a second straight line L2) that passes through the container axis O and the second corner 48 in the plan view. The second magnet 43 is located on the second straight line L2.

As shown in FIG. 4, the second magnet 43 is attached to the second inner cylinder 42. The second inner cylinder 42 is provided with a second recess 51. The second recess 51 is recessed downward. The second recess 51 is open upward. The second magnet 43 is fitted into the second recess 51.

In this embodiment, as shown in Fig. 3, a rib 52 is provided on the inner peripheral surface of the lower end portion 40a of the lid 40. The rib 52 is slidable on the outer peripheral surface of the protrusion 32 in the container axis O direction. In this embodiment, the rib 52 is a vertical rib extending in the container axis O direction. The upper edge of the rib 52 is connected to the step 50. The rib 52 extends downward from the step 50.
2 , the ribs 52 are provided on at least two of the four second side portions 49. In the present embodiment, the ribs 52 are provided on all four second side portions 49. The ribs 52 are provided at the midpoints of the second side portions 49. Each rib 52 slides on the outer circumferential surface of each first side portion 35 of the protrusion 32.

The radial size of the lower end of the rib 52 gradually decreases as it goes downward. In this embodiment, in a vertical cross-sectional view of the rib 52, the lower edge 52a of the rib 52 is curved and protrudes radially inward. The radially outer end of the lower edge 52a of the rib 52 is continuous with the lower end surface 40b of the lid 40 (the lower end surface of the enlarged diameter portion 45).

As described above, according to the container with lid 10 of this embodiment, the rib 52 can slide on the outer peripheral surface of the protrusion 32 in the container axis O direction. Therefore, when the protrusion 32 of the container body 20 is disposed in the lower end portion 40a of the lid 40 in order to attach the lid 40 to the container body 20 in a state in which the lid 40 is detached from the container body 20, the rib 52 slides on the outer peripheral surface of the protrusion 32 in the container axis O direction. Therefore, when the second magnet 43 is attracted to the first magnet 26, the speed at which the lid 40 moves relative to the container body 20 can be reduced. As a result, the impact generated when the lid 40 contacts the container body 20 can be mitigated, and the generated sound can be suppressed. This can ensure, for example, a luxurious feel of the container with lid 10.
Furthermore, the rib 52 is provided on the inner peripheral surface of the lower end portion 40a of the lid body 40, not on the outer peripheral surface of the protrusion 32. This makes it possible to make the rib 52 less visible from the outside. As a result, the appearance of the lidded container 10 can be improved. This can, for example, further ensure the luxurious feel of the lidded container 10.

In a vertical cross-sectional view of the rib 52, the lower edge 52a of the rib 52 is curved and protrudes radially inward. Therefore, for example, in a vertical cross-sectional view of the rib 52, the area of contact of the rib 52 itself with the container body 20 can be made smaller than when the lower edge 52a of the rib 52 is a straight line extending radially. As a result, the impact described above can be more effectively mitigated.

The first magnet 26 is disposed at a position corresponding to the first corner 34. The second magnet 43 is disposed at a position corresponding to the second corner 48. Ribs 52 are provided on at least two of the four second sides 49. Therefore, in a plan view of the lidded container 10, the positions of the first magnet 26 and the second magnet 43 can be made different from the positions of the rib 52. This allows the rib 52 to slide effectively on the outer peripheral surface of the protrusion 32.

In this embodiment, the first magnet 26 and the second magnet 43 attract each other. Therefore, when the second magnet 43 as an attraction member is attracted to the first magnet 26, the first magnet 26 is also attracted to the second magnet 43. Therefore, compared to, for example, a case in which a magnetic body that is simply attracted to the first magnet 26 is used as the attraction member, the first magnet 26 and the second magnet 43 attract each other strongly, and the lid body 40 is firmly attached to the container body 20. In addition, the speed at which the lid body 40 moves relative to the container body 20 can be easily increased. Therefore, the effect of the rib 52 reducing the movement speed of the lid body 40 is significantly effective.

The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

The shape of the protrusion 32 and the shape of the lower end 40a of the lid 40 in a plan view do not have to be rectangular. For example, each of these shapes in a plan view may be circular.
In a vertical cross-sectional view of the rib 52, the lower end edge 52a of the rib 52 does not have to be curved. For example, the lower end edge 52a of the rib 52 may be linear and extend in the radial direction.
Although the second magnet 43 is used as the suction member attracted by the first magnet 26, the present invention is not limited to this. A magnetic material such as iron may be used as the suction member instead of the second magnet 43. In this case, it is possible to appropriately adopt a configuration in which the first magnet 26 is provided on either the container body 20 or the lid body 40, and the magnetic material as the suction member is provided on the other of the container body 20 and the lid body 40.

In addition, the components in the above embodiment may be replaced with well-known components as appropriate without departing from the spirit of the present invention, and the above-mentioned modifications may be combined as appropriate.
