Description

Technical Field

[0001] This invention relates to containers. Background Technology

[0002] It is generally known that when closing the opening of a container body, the lid is threaded onto the container body. Patent Document 1 discloses a structure that closes the opening of the container body by threading an outer lid onto the container body.

[0003] [Existing Technical Documents]

[0004] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2024-94541 Summary of the Invention

[0006] [The problem the invention aims to solve]

[0007] In a structure where the lid is threaded onto the container body to seal the opening of the container, airtightness is ensured. However, when the lid is not sealing the opening of the container body, it is completely detached from the container body. Therefore, there are issues that reduce ease of use, such as the need to ensure the proper placement of the lid and concerns about losing the lid.

[0008] The purpose of this invention is to provide a container that can improve ease of use while ensuring airtightness.

[0009] [Methods for solving the problem]

[0010] To achieve the above objectives, the container of the present invention has,

[0011] The container body has a bottom and a cylindrical first side portion, and receives and holds an object through an opening facing the bottom.

[0012] The middle cover portion is configured to allow the opening to be freely opened and closed, and

[0013] The outer cover, which has a top plate and a cylindrical second side surface, is installed on the container body to cover the middle cover when the opening is closed by the middle cover.

[0014] The first side portion has,

[0015] The cylindrical upper side surface has a threaded structure on its outer circumferential surface that engages with the threaded structure of the second side surface.

[0016] The lower side surface is continuous with the bottom side of the upper side surface.

[0017] An assembly portion, configured to be inserted into a part of the middle cover portion, spans the upper side surface portion and the lower side surface portion, extending from the opening toward the bottom side, and is formed for at least a specified length.

[0018] The middle cover portion has,

[0019] The circular plate portion, which is held inside the top plate portion of the outer cover portion, is freely rotatable in the circumferential direction, and

[0020] A tongue, which is movable in the vertical direction, is inserted into the assembly part to keep the circular plate part free to open and close the opening.

[0021] In the present invention configured as described above, the opening of the container body is sealed by the threaded engagement of the outer cover with the container body. This ensures airtightness. When the threaded engagement of the outer cover and the container body is disengaged to open the opening of the container body, the circular plate portion of the middle cover is held inside the outer cover, while the tongue portion holding the circular plate portion of the middle cover is inserted into the assembly portion of the container body. Thus, even when the opening of the container body is not sealed, the outer cover portion remains connected to the container body via the middle cover portion, and ease of use is not compromised.

[0022] Furthermore, the tongue can be structured such that it is rotatably inserted into the assembly portion relative to the first side portion via a support shaft located at the end opposite to the circular plate portion.

[0023] In this structure, the opening can be opened by opening the outer cover.

[0024] It also includes: a cylindrical component disposed within the container body portion along the inner side surface of the first side portion, and

[0025] A press-in component is configured to move within the cylindrical component along its inner surface.

[0026] The cylindrical component has an axially extending communication portion between its outer wall portion along the inner side surface of the first side portion and the inner wall portion along which the pressing component moves.

[0027] The inner wall portion has a communication structure at its end on the bottom side of the container body portion, which connects the inner region of the inner wall portion to the communication portion between that end and the bottom of the container body portion.

[0028] The connecting portion may have a structure in which an outlet is provided at the end opposite to the connecting structure to discharge the contents contained within the container body.

[0029] In this structure, the contents contained in the container body are discharged from the outlet by simply moving the pressing component along the inner side of the cylindrical component, thus allowing for hygienic use without the need for removal tools.

[0030] Alternatively, the structure could be as follows: with the discharge port covered by the circular plate portion, the outer cover portion is installed on the container body portion, thereby ensuring the airtightness of the discharge port.

[0031] This structure ensures the airtightness of the outlet.

[0032] Furthermore, the press-in component may be configured to ensure a specified airtightness between itself and the inner surface of the cylindrical component, while being movable within the cylindrical component along the inner surface of the cylindrical component.

[0033] In this structure, although the pressed-in component can move inside the cylindrical component, the airtightness between the pressed-in component and the inner surface of the cylindrical component can still be ensured.

[0034] In addition, the cylindrical component may have a retaining surface around the outlet to hold the contents discharged from the outlet.

[0035] In this structure, the contents discharged from the outlet can be temporarily held in place by the retaining surface.

[0036] Furthermore, the retaining surface may be structured such that it slopes from the periphery of the cylindrical component toward the center of the axis of the cylindrical component toward the bottom side of the container body.

[0037] In such a structure, it is easy to remove the contents held by the retaining surface.

[0038] [The effects of the invention]

[0039] According to the present invention, while ensuring airtightness, ease of use can be improved. Attached Figure Description

[0079] 60 Press-in Parts Detailed Implementation

[0080] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0081] <Overall Structure>

[0082] Figure 1 This is a diagram illustrating one embodiment of the container of the present invention, viewed from an obliquely upward angle. Figure 2 It will be from Figure 1 The diagram shows the container 1 with its outer cover 10 removed, viewed from an obliquely upward angle.

[0083] This implementation method is as follows: Figure 1 As shown, the outer cover 10 is detachably mounted on the container body 20. Furthermore, as... Figure 2 As shown, a middle cover 30 is installed on the container body 20.

[0084] The following describes each structural component.

[0085] <Outer Cover Part 10>

[0086] Figure 3 It is Figure 1 The diagram shows the outer cover 10 viewed from a slightly lower angle.

[0087] Figure 1 The outer cover 10 shown is as follows Figure 3 As shown, it has a circular top plate portion 11 and a cylindrical side plate portion 12 continuous with the periphery of the top plate portion 11. The side plate portion 12 is an example of the second side plate portion in this invention. A threaded structure 24 (see reference) is formed on the inner peripheral surface of the side plate portion 12, which is connected to the threaded structure 24 provided on the container body portion 20. Figure 4 The threaded structure 13 engages with the thread. Furthermore, on the inner circumferential surface of the side portion 12, further from the top plate portion 11 than the threaded structure 13, a plurality of inwardly protruding ribs 14 are provided. Moreover, the height of the ribs 14 is such that the circular plate portion 31 of the middle cover portion 30 can be held between the top plate portion 11 and the ribs 14 (see reference). Figure 5 The height of the top plate portion 11 and the rib 14 is greater than the thickness of the circular plate portion 31 of the middle cover portion 30.

[0088] <Container body part 20>

[0089] Figure 4 It is Figure 1 The container body 20 shown is viewed from an obliquely upward angle.

[0090] Figure 1 The container body 20 shown is as follows Figure 4 As shown, it has a circular bottom 22 and a cylindrical side portion 21 that is continuous with the periphery of the bottom 22, and an opening 23 facing the bottom 22 on the opposite side of the bottom 22.

[0091] The side portion 21 has a lower side portion 21b that is continuous with the bottom 22, and an upper side portion 21a that is continuous from the lower side portion 21b to the opposite side of the bottom 22. The outer diameter of the upper side portion 21a is the same as the inner diameter of the side portion 12 of the outer cover portion 10, and its outer circumferential surface is provided with a threaded structure 24 that engages with a threaded structure 13 formed on the inner circumferential surface of the side portion 12 of the outer cover portion 10. Thus, by engaging the threaded structure 13 of the outer cover portion 10 with the threaded structure 24 of the upper side portion 21a, the outer cover portion 10 can be installed so that it can be removed from the container body portion 20. The height of the upper side portion 21a can be the same as the height of the side portion 12 of the outer cover portion 10.

[0092] The lower side surface portion 21b is an example of the first side surface portion in this invention. The outer diameter of the lower side surface portion 21b can be the same as the outer diameter of the side surface portion 12 of the outer cover portion 10. With such a structure, as Figure 1As shown, when the outer cover 10 is installed on the container body 20, the outer peripheral surface of the side surface 12 of the outer cover 10 and the outer peripheral surface of the side surface 21 of the container body 20 can be aligned.

[0093] On the side portion 21, a recess 25 is provided on a portion in the circumferential direction. The recess 25 is an example of an assembly portion in this invention. The recess 25 is formed such that it is recessed inward from the outer periphery of the side portion 21, spanning the upper side portion 21a and the lower side portion 21b, and forms a tongue 32 (see reference) corresponding to the middle cover portion 30 from the opening 23 toward the bottom 22. Figure 5 The length of the recess 25 is specified. Furthermore, the length of the upper side surface 21a and lower side surface 21b in a continuous direction is greater than or equal to the length of the tongue 32 of the middle cover 30, and can span the entire area of ​​the side surface 21. Within the recess 25, in the region corresponding to the lower side surface 21b, there is a circumferentially recessed engagement groove 26 extending from both sides of the recess 25 to the lower side surface 21b. The engagement groove 26 has a specified length in a continuous direction between the upper side surface 21a and the lower side surface 21b. Furthermore, as an assembly part, the recess 25 is not limited to being formed by recessing inward from the outer periphery of the side surface 21. For example, it could be a cut extending from the opening 23 side of the upper side surface 21a across the lower side surface 21b for a specified length.

[0094] The container body 20 houses a containment discharge tool 40. The detailed structure of the containment discharge tool 40 will be described later.

[0095] <Middle Cover Section 30>

[0096] Figure 5 It is Figure 2 The diagram shown depicts the middle cover 30 viewed from an oblique, upward angle. Figure 6 It is Figure 2 The diagram shows the middle cover 30 viewed from a slightly lower angle.

[0097] Figure 2 The middle cover 30 shown is as follows Figure 5 and Figure 6 As shown, it has a circular plate portion 31 and a tongue portion 32.

[0098] The circular plate portion 31 is circular, and its outer diameter is almost the same as the outer diameter of the upper side portion 21a, thereby closing the opening 23 of the container body portion 20. That is, the middle cover portion 30 is configured to allow the opening 23 of the container body portion 20 to be opened and closed freely through the circular plate portion 31.

[0099] The tongue 32 is configured to extend from a portion of the periphery of the circular plate portion 31 in the direction facing the surface of the circular plate portion 31. A support shaft 33 is provided on the tongue 32 at the end opposite to the circular plate portion 31. The support shaft 33 is configured to protrude from the tongue 32 in the tangential direction to the portion where the circular plate portion 31 and the tongue 32 are connected.

[0100] The middle cover 30 thus constructed, as Figure 2 As shown, it is installed on the container body 20. At this time, the tongue 32 of the middle cover 30 enters the recess 25 of the container body 20, and the support shaft 33 provided on the tongue 32 engages with the engaging groove 26 provided on the recess 25 of the container body 20. As described above, the support shaft 33 is provided to protrude from the tongue 32 in the tangential direction to the part where the circular plate 31 connects with the tongue 32. On the other hand, the engaging groove 26 is recessed circumferentially from both sides of the recess 25 to the lower side surface portion 21b. Therefore, with the support shaft 33 engaged with the engaging groove 26, the middle cover 30 can rotate freely relative to the container body 20 about the support shaft 33. That is, the tongue 32 is rotatably inserted into the recess 25 relative to the lower side surface portion 21b via the support shaft 33. Therefore, by rotating together with the tongue 32, the opening 23 of the container body 20 can be closed, while the tongue 32 keeps the circular plate 31 free to open and close the opening 23. Furthermore, as described above, the engaging groove 26 has a specified length in the continuous direction of the upper side surface 21a and the lower side surface 21b. Therefore, the middle cover 30, relative to the container body 20, can move the length of the engaging groove 26 in the continuous vertical direction of the upper side surface 21a and the lower side surface 21b. Thus, the tongue 32 is movably inserted into the recess 25 of the container body 20 in the vertical direction. Furthermore, the circular plate 31 is sandwiched and held between the top plate 11 and the rib 14 of the outer cover 10. At this time, the circular plate 31 is only sandwiched between the top plate 11 and the rib 14 of the outer cover 10, and is therefore held in a state where it can rotate freely in the circumferential direction between the top plate 11 and the rib 14 of the outer cover 10.

[0101] <Containment Discharge Tool 40>

[0102] Figure 7 It means Figure 4 The diagram showing the detailed structure of the containment discharge tool 40 is viewed from an oblique top.

[0103] Figure 4 The container discharge tool 40 shown is as follows Figure 7 As shown, it has a cylindrical member 50 and a press-in member 60, and is installed such that the press-in member 60 is housed within the cylindrical member 50. Then, as... Figure 4 As shown, the container discharge tool 40 is installed such that it is housed within the container body 20.

[0104] <Cylindrical component 50>

[0105] Figure 8 It is Figure 7 The diagram shows the cylindrical component 50 viewed from an oblique angle. Figure 9 It is Figure 7The diagram shows the cylindrical component 50 viewed from a slightly downward angle. Figure 10 It is Figure 7 The diagram shows the cylindrical component 50 viewed from below.

[0106] Figure 7 The cylindrical component 50 shown is as follows Figures 8-10 As shown, it has a side portion 51 and a retaining portion 56.

[0107] The side portion 51 has an outer wall portion 51a and an inner wall portion 51b. Both the outer wall portion 51a and the inner wall portion 51b are cylindrical with openings at both ends. Although the outer wall portion 51a and the inner wall portion 51b have the same axial length, the outer wall portion 51a has a larger diameter than the inner wall portion 51b. The inner wall portion 51b is provided inside the outer wall portion 51a while their centers are offset from each other, thus creating a space in a portion between the outer wall portion 51a and the inner wall portion 51b, while the other parts remain integrated. A connecting portion 53 is provided in the space created between the outer wall portion 51a and the inner wall portion 51b.

[0108] On one end of the inner wall portion 51b, a communication opening 54 is provided in the region facing the communication portion 53. The communication opening 54 is an example of the communication structure in this invention, and is formed by cutting off a portion of the inner wall portion 51b. Furthermore, the shape of the communication opening 54 is not limited to the quadrilateral shown in the figure. In addition, there can be multiple communication openings 54.

[0109] A retaining portion 56 is provided on the end opposite to the end with the communication port 54 at both axial ends of the side portion 51, in a region containing the communication portion 53. The retaining portion 56 has, for example, a crescent shape and covers a portion of one end of the cylindrical member 50. The retaining portion 56 is provided in the region containing the communication portion 53, whereby a discharge port 55 is provided on the end of the communication portion 53 opposite to the communication port 54. Thus, the communication portion 53 extends axially along the cylindrical member 50 from the communication port 54 to the discharge port 55. Furthermore, the retaining portion 56 has a structure in which its upper surface is a retaining surface 56a, and a retaining surface 56a is provided around the discharge port 55. The retaining surface 56a extends from around the cylindrical member 50 where the discharge port 55 is provided toward the center of the axis of the cylindrical member 50, and slopes toward the end of the cylindrical member 50 where the communication port 54 is provided. Furthermore, a cap-like member can be used to cover the discharge port 55. At this time, the cover-like component may, for example, have a protrusion on its back side, and be installed in such a way that the protrusion fits into the outlet 55. When providing the cover-like component, it is preferable to provide a gap, such as that for the contents entering the communication portion 53 to be discharged from the outlet 55, between the outlet 55 and the retaining surface 56a. Furthermore, the number of outlets 55 is not limited to one, but may be multiple. In addition, the shape of the outlet 55 is not limited to the approximately quadrilateral shape shown in the figure, but may be various shapes such as circular, oval, and star-shaped.

[0110] Except for a portion thereof, the outer diameter of the outer wall portion 51a is smaller than the inner diameter of the container body portion 20. Therefore, as... Figure 4 As shown, the container discharge tool 40 can be housed within the container body 20. Furthermore, the inner diameters of the two ends of the inner wall portion 51b along the axial direction are identical. That is, the inner diameter is cylindrical.

[0111] <Press-in component 60>

[0112] Figure 11 It is Figure 7 The diagram shown depicts the press-in component 60 viewed from an oblique top angle. Figure 12 It is Figure 7 The figure shows the press-in component 60 viewed from the side.

[0113] Figure 7 The press-in component 60 shown is composed of an elastic component, such as... Figure 11 and Figure 12 As shown, it has a bottom 61 and a side 62.

[0114] The bottom 61 is circular.

[0115] The side portion 62 is provided along the outer periphery of the bottom portion 61. The side portion 62 is curved outward from the upper and lower ends, and the press-in member 60 is made of an elastic member, so that it can be deformed by external force, and the position of the upper and lower ends can be moved towards the center of the side portion 62.

[0116] The outer diameter of the press-in member 60 configured in this way is the same as or slightly larger than the inner diameter of the inner wall portion 51b of the cylindrical member 50. Therefore, the press-in member 60 can be installed inside the cylindrical member 50 with its side portion 62 facing the inner side of the inner wall portion 51b of the cylindrical member 50. Furthermore, the press-in member 60 is made of an elastic member. Therefore, when the outer diameter of the press-in member 60 is slightly larger than the inner diameter of the inner wall portion 51b of the cylindrical member 50, the side portion 62 deforms as follows, shifting the positions of the upper and lower ends of the side portion 62 towards the center of the side portion 62. This allows the press-in member 60 to be installed inside the cylindrical member 50.

[0117] Furthermore, as described above, the inner wall portion 51b of the cylindrical member 50 has the same inner diameter at both ends in the axial direction. That is, the inner diameter of the side portion 51 is cylindrical. Therefore, the press-in member 60 installed inside the cylindrical member 50 can move axially along the inner side of the cylindrical member 50.

[0118] <Explanation of its function when used>

[0119] The following explains how to use the container 1 as described above and its function during use.

[0120] First, it should be explained that the opening 23 of the outer cover 10 is used to open and close.

[0121] Figures 13-15 This is a perspective view taken from the side, used to illustrate the function of opening and closing the opening 23 of the outer cover 10.

[0122] When the threaded structure 13 of the outer cover 10 and the threaded structure 24 of the container body 20 are engaged, such as Figure 13 As shown, the opening 23 of the container body 20 is covered and closed by the circular plate portion 31 of the middle cover portion 30 and the outer cover portion 10. Here, as described above, the container body 20 houses a container discharge tool 40, which has a discharge port 55. Then, with the threaded structure 13 of the outer cover portion 10 and the threaded structure 24 of the container body 20 engaged, the discharge port 55 is also covered and closed by the circular plate portion 31 of the middle cover and the outer cover portion 10. Thus, the airtightness of the opening 23 and the discharge port 55 is ensured by the threaded engagement of the outer cover portion 10 and the container body 20. Furthermore, with the threaded structure 13 of the outer cover portion 10 and the threaded structure 24 of the container body 20 engaged, the opening 23 and the discharge port 55 are covered and closed by the circular plate portion 31 of the middle cover portion 30. Therefore, the airtightness of the opening 23 and the outlet 55 is also ensured by the circular plate portion 31 of the middle cover portion 30.

[0123] From this state, the outer cover 10 is rotated circumferentially, disengaging the threads of the outer cover 10 and the container body 20. Thus, as... Figure 14 As shown, relative to the container body 20, the outer cover 10 separates in the direction of disengagement from the threaded engagement of the threaded structure 13 of the outer cover 10 and the threaded structure 24 of the container body 20. Here, regarding the middle cover 30, a tongue 32 is inserted into the recess 25 provided on the side surface 21 of the container body 20, and a circular plate 31 continuous with the tongue 32 is held between the top plate 11 and the rib 14 of the outer cover 10. However, the circular plate 31 remains circumferentially rotatable between the top plate 11 and the rib 14 of the outer cover 10. Therefore, to disengage the threaded engagement of the threaded structure 13 of the outer cover 10 and the threaded structure 24 of the container body 20, the outer cover 10 can be rotated circumferentially.

[0124] Furthermore, the tongue 32 is engaged with the engaging groove 26 provided in the recess 25 via the support shaft 33 and is thus inserted into the recess 25. As described above, the engaging groove 26 has a specified length in the continuous vertical direction of the upper side surface 21a and the lower side surface 21b. Therefore, the middle cover 30, relative to the container body 20, can move the length of the engaging groove 26 in the continuous vertical direction of the upper side surface 21a and the lower side surface 21b. Therefore, when the outer cover 10 is rotated circumferentially to disengage the threads of the threaded structure 13 of the outer cover 10 and the threaded structure 24 of the container body 20, as... Figure 14 As shown, the outer cover portion 10 does not tilt relative to the container body portion 20, and separates in the direction in which the threaded structure 13 of the outer cover portion 10 and the threaded structure 24 of the container body portion 20 are disengaged. At this time, the length of the engaging groove 26 in the continuous direction of the upper side surface portion 21a and the lower side surface portion 21b is greater than or equal to the length of the upper side surface portion 21a in the continuous direction of the lower side surface portion 21b. Thus, until the threaded engagement of the threaded structure 13 of the outer cover portion 10 and the threaded structure 24 of the container body portion 20 is completely disengaged, the outer cover portion 10 does not tilt and can separate in the direction in which the threaded engagement of the threaded structure 13 of the outer cover portion 10 and the threaded structure 24 of the container body portion 20 is disengaged.

[0125] As described above, the support shaft 33 of the tongue 32 provided in the middle cover portion 30 engages with the engaging groove 26 of the container body portion 20. Therefore, after the threaded engagement of the threaded structure 13 of the outer cover portion 10 and the threaded structure 24 of the container body portion 20 is completely disengaged, as... Figure 15 As shown, the middle cover 30 can rotate relative to the container body 20 about the support shaft 33. Then, the opening 23 can be in a state where it is not closed by the middle cover 30 and the outer cover 10. In this way, the opening 23 can be opened in the same way as opening the outer cover 10.

[0126] At this time, the support shaft 33 of the tongue 32 provided in the middle cover 30 engages with the engaging groove 26 of the container body 20. Therefore, even if the opening 23 is not closed through the middle cover 30 and the outer cover 10, the outer cover 10 is still connected to the middle cover 30 and is not separated from the container body 20, so the ease of use will not be affected.

[0127] When closing the opening 23 of the container body 20, which has never been closed by the outer cover portion 10 and the middle cover portion 30, firstly, as... Figure 14As shown, the outer cover portion 10 of the retaining middle cover portion 30 faces the opening 23 of the container body portion 20. At this time, the middle cover portion 30 held by the outer cover portion 10 can also move the length of the engaging groove 26 in the continuous vertical direction of the upper side surface portion 21a and the lower side surface portion 21b relative to the container body portion 20 while the tongue 32 is inserted into the recess 25. In addition, the length of the engaging groove 26 in the continuous direction of the upper side surface portion 21a and the lower side surface portion 21b can be greater than or equal to the length of the upper side surface portion 21a in the continuous direction of the lower side surface portion 21b. As a result, the outer cover portion 10 of the retaining middle cover portion 30 is not tilted toward the opening 23 of the container body portion 20, but faces it.

[0128] Then, the outer cover 10 is rotated circumferentially. By engaging the threaded structure 13 of the outer cover 10 with the threaded structure 24 of the container body 20, the opening 23 and the outlet 55 are sealed by the circular plate portion 31 of the outer cover 10 and the middle cover 30, ensuring airtightness. At this time, as described above, the circular plate portion 31 of the middle cover 30 is positioned between the top plate portion 11 and the rib 14 of the outer cover 10, allowing for free circumferential rotation. Therefore, in order to engage the threaded structure 13 of the outer cover 10 with the threaded structure 24 of the container body 20, the outer cover 10 can be rotated circumferentially.

[0129] The following explains how to use the contents of container 1 and their function when they are taken out.

[0130] When taking out the contents contained in container 1, firstly, as described above, untie the threaded engagement of the threaded structure 13 of the outer cover 10 and the threaded structure 24 of the container body 20, so that the opening 23 is not closed by the middle cover 30 and the outer cover 10.

[0131] Then, the pressing member 60 is pressed into the bottom 22 side of the container body 20. As described above, the outer diameter of the pressing member 60 is the same as or slightly larger than the inner diameter of the inner wall portion 51b of the cylindrical member 50. Therefore, while ensuring airtightness between the side portion 62 of the pressing member 60 and the inner side surface of the inner wall portion 51b of the cylindrical member 50, the pressing member 60 moves towards the bottom 22 side of the container body 20. That is, the pressing member 60 is configured to ensure a specified airtightness between itself and the inner side surface of the cylindrical member 50, while being able to move along the inner side surface of the cylindrical member 50 within the cylindrical member 50. Therefore, when the pressing member 60 is pressed into the bottom 22 side of the container body 20 for use of the contents contained in the container 1, it is difficult for the contents contained in the container 1 to leak out between the pressing member 60 and the cylindrical member 50. Specifically, when the outer diameter of the press-in member 60 is slightly larger than the inner diameter of the inner wall portion 51b of the cylindrical member 50, the press-in member 60 is made of an elastic member. As a result, the side portion 62 deforms by shifting the positions of its upper and lower ends towards the center of the side portion 62. Then, through its restoring force, it is pressed against the inner surface of the inner wall portion 51b of the cylindrical member 50. This reliably ensures airtightness between the side portion 62 of the press-in member 60 and the inner surface of the inner wall portion 51b of the cylindrical member 50.

[0132] When the pressing member 60 moves toward the bottom 22 of the container body 20, the contents contained in the space formed between the side portion 51 of the cylindrical member 50, the bottom 22 of the container body 20, and the bottom 61 of the pressing member 60 enter the connecting portion 53 through the connecting port 54. Here, the space formed between the side portion 51 of the cylindrical member 50, the bottom 22 of the container body 20, and the bottom 61 of the pressing member 60, except for the connecting port 54, has no connection to the outside. Therefore, when the pressing member 60 moves toward the bottom 22 of the container body 20, the contents contained in the space formed between the side portion 51 of the cylindrical member 50, the bottom 22 of the container body 20, and the bottom 61 of the pressing member 60 enter the connecting portion 53 through the connecting port 54.

[0133] One end of the connecting part 53 communicates with the space formed between the side part 51 of the cylindrical component 50, the bottom 22 of the container body part 20 and the bottom 61 of the pressing part 60 through the connecting port 54, and the other end communicates with the outside of the container 1 through the discharge port 55.

[0134] Therefore, the contents that enter the connecting part 53 through the connecting port 54 are further pressed into the bottom 22 side by the pressing member 60, move toward the discharge port 55, and are discharged from the discharge port 55.

[0135] Thus, by moving the pressing member 60 along the inner side of the cylindrical member 50, the contents contained in the container 1 enter the communicating portion 53 and are discharged from the discharge port 55. Therefore, it is hygienic to use the container 1 without inserting fingers to retrieve the contents. Furthermore, no retrieval tool is needed to remove the contents from the container 1. Therefore, there is no need to hold a separate retrieval tool. Moreover, there is no need to provide a structure or space within the container 1 to hold the retrieval tool, and the container 1 does not become large.

[0136] Furthermore, by pressing the pressing member 60 into the bottom 22 side of the container body 20, the contents contained in the container 1 are discharged from the discharge port 55, thus allowing the discharge of the contents to be directly felt. Moreover, an amount corresponding to the amount of pressing into the bottom 22 side of the container body 20 of the pressing member 60 is discharged from the discharge port 55, making it easy to adjust the discharge amount of the contents. Furthermore, the remaining amount of the contents can be felt by the position of the pressing member 60.

[0137] When the contents contained in container 1 are discharged from the discharge port 55, as described above, the discharge port 55 has a retaining surface 56a around it, thereby discharging the contents discharged from the discharge port 55 onto the retaining surface 56a. Therefore, the contents discharged from the discharge port 55 can be temporarily retained on the retaining surface 56a. Furthermore, the amount of contents discharged from the discharge port 55 can be sensed by the amount of contents retained on the retaining surface 56a.

[0138] Then, the contents held on the holding surface 56a of the holding part 56 are wiped off with a finger and applied to the skin or for other uses. Here, as described above, the holding surface 56a is inclined from the periphery of the cylindrical member 50 with the outlet 55 toward the center of the axis of the cylindrical member 50 toward the end of the cylindrical member 50 with the communication port 54. Therefore, for example, when wiping the contents with a fingertip at the center side of the axis of the cylindrical member 50, it is easy to wipe off the contents held on the holding surface 56a.

[0139] Furthermore, the aforementioned container discharge tool 40 can be provided as a replacement. In this case, with the container housed within the space enclosed by the cylindrical member 50 and the pressing member 60, the end of the cylindrical member 50 located on the communication port 54 side is covered with an aluminum seal. Then, in use, the aluminum seal can be peeled off, and the container discharge tool 40 can be housed within the container body 20, thereby performing the installation.

[0140] In this way, once the containment is used up, the container 1 can be reused by simply replacing the containment discharge tool 40.

[0141] (Applicable examples)

[0142] Figure 16This is a diagram showing an applicable example of the container, and it shows the state in which the outer cover 10 and the middle cover 30 are opened.

[0143] like Figure 16 As shown, the container 1 can hold the paintbrush 5 in the space of the press-in component 60.

[0144] Then, the pressing member 60 is pressed in in the same manner as described above, thereby discharging the contents contained in the container body 20 from the discharge port 55. The contents discharged from the discharge port 55 are discharged onto the holding surface 56a, so the contents held on the holding surface 56a can be wiped off and used by the brush 5.
