Description

[Technical Field]

[0001] The present invention relates to a dispensing container. [Background technology]

[0002] There is a dispensing container in which a solid glue is stored as a solid content in a cylindrical sleeve body, and this solid glue is dispensed for use. When the solid glue dries, it hardens and becomes unusable or its quality deteriorates, so it is important that the inside of the dispensing container remains airtight when the cap body is attached.

[0003] In a dispensing container, generally, a shaft is inserted into the sleeve from its rear, the shaft is inserted into the solid glue contained inside the sleeve, and a grip for rotating the shaft is disposed at the rear of the sleeve. An airtight structure between the sleeve and the shaft is provided inside the sleeve forward of the grip (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 5-89280 Summary of the Invention [Problem to be solved by the invention]

[0005] If the airtight structure between the sleeve body and the shaft body is provided forward of the grip body, the dispensing container will be long in the axial direction as a whole. Dispensing containers are often stored in pencil cases together with writing implements, but if the dispensing container is long, it will take up a lot of space in the pencil case.

[0006] An object of the present invention is to provide a more compact dispensing container while maintaining a sufficiently airtight structure. [Means for solving the problem]

[0007] (1) In order to solve the above problem, the present invention provides a dispensing container comprising: a sleeve body having a storage cylindrical portion that stores solid contents movably in the axial direction; a shaft body that is inserted into the storage cylindrical portion from the rear side in the axial direction and rotates around its axis to drive the solid contents in the axial direction; and a grip body that is arranged on the rear side of the storage cylindrical portion and connected to the shaft body and rotates around its axis relative to the storage cylindrical portion to rotate the shaft body, wherein an airtight structure between the sleeve body and the shaft body is provided inside the grip body in the axial direction.

[0008] (2) A locking structure between the sleeve body and the shaft body may be provided inside the grip body in the axial direction.

[0009] (3) The position of the grip body in the axial direction may be restricted by sandwiching the grip body between the sleeve body and the shaft body.

[0010] (4) The outer circumferential shape of the front end of the grip body and the outer circumferential shape of the rear end of the tubular housing portion may be substantially the same.

[0011] (5) A grip front wall portion perpendicular to the axis may be provided on the front side of the grip body. [Effects of the Invention]

[0012] According to the present invention, it is possible to provide a more compact dispensing container while maintaining a sufficiently airtight structure. [Brief explanation of the drawings]

[0014] Below, we will explain a dispensing container 1 according to an embodiment of the present invention. The dispensing container 1 is a container that stores solid contents 100 therein and can dispense only the required amount of the solid contents 100 for use. Hereinafter, the side from which the solid contents 100 are dispensed will be referred to as the front, the opposite side as the rear, and the dispensing direction (front-to-back direction) as the axis Z direction. Note that the cross section of the dispensing container 1 taken in a direction perpendicular to the dispensing direction is substantially rectangular, and the axis Z passes through the center of this substantially rectangular cross section. Furthermore, in explaining each component of the dispensing container 1, when viewed in a cross section perpendicular to the axis Z, the axis Z side will be referred to as the inside and the opposite side as the outside.

[0015] Fig. 1 is a perspective view of a dispensing container 1 of an embodiment as seen obliquely from the front. Fig. 2 is an exploded perspective view of a dispensing container 1 of an embodiment as seen obliquely from the front. Fig. 3 is an exploded perspective view of a dispensing container 1 of an embodiment as seen obliquely from the rear. Fig. 4 is an XZ cross-sectional view of the dispensing container 1 of an embodiment at the center in the Y-axis direction in Fig. 1. Note that Figs. 2 and 3 omit the illustration of solid contents 100.

[0016] (solid content 100) FIG. 4 shows the solid content 100 contained in the dispensing container 1. The solid content 100, when held at its rear by the holder 40 described below, is, for example, a solid glue, and has a cross-sectional shape perpendicular to the axis Z that is not a square but is a substantially rectangular shape, and is generally a substantially rectangular parallelepiped. However, the cross-sectional shape of the solid content 100 is not limited to this, and may be, for example, a perfect circle, a substantially ellipse, a quadrilateral such as a square or a rhombus, or a polygonal shape such as a triangle or a pentagon (including so-called Reuleaux polygons). Furthermore, the solid content 100 may be, other than the solid glue, cosmetics such as foundation, lipstick, or lip balm, or solid drawing materials such as crayons.

[0017] (Dispenser 1) The dispensing container 1 is generally rectangular parallelepiped, and its cross-sectional shape perpendicular to the axis Z is approximately similar to but slightly larger than the cross-sectional shape of the solid contents 100, and it can accommodate the solid contents 100 inside. In the following description, the long side direction of the rectangular cross-section is defined as the X direction, and the short side direction is defined as the Y direction.

[0018] The dispensing container 1 comprises a sleeve body 10, a cap body 20 that is detachable from the sleeve body 10, a seal body 30 that is arranged to maintain airtightness between the sleeve body 10 and the cap body 20, a holder 40 that holds solid contents 100 (shown in Figure 4) inside the sleeve body 10, a shaft body 50 that drives the holder 40 and the solid contents 100 in the axial Z direction, and a grip body 60 that covers the rear side of the shaft body 50.

[0019] The dispensing container 1 also has a first airtight structure A (shown in Figures 4 and 5) including a seal body 30, which is provided on the front side of the dispensing container 1 between the sleeve body 10 and the cap body 20, and a second airtight structure B (shown in Figure 4) which is provided on the rear side of the dispensing container 1 between the sleeve body 10 and the shaft body 50.

[0020] (Sleeve body 10) The sleeve body 10 has a tubular housing portion 11 for housing a solid content 100, and a rear tubular portion 12 extending rearward from the tubular housing portion 11.

[0021] (Housing tube portion 11) The tubular storage portion 11 accommodates the solid contents 100 and the holder 40 that holds the solid contents 100 so that they can move in the direction of the axis Z. The tubular storage portion 11 is a rectangular tubular member having a cross section perpendicular to the axis Z that is substantially rectangular, and includes a tubular main body 13 and a cap attachment portion 14 that extends forward from the tubular main body 13.

[0022] The inner surface of the casing tube portion 11 has a substantially constant cross-section in the Z-axis direction, and in this embodiment, this shape (the shape of the inner surface of the casing tube portion 11 in a cross section perpendicular to the Z-axis) is a non-circular, substantially rectangular shape. That is, there is no step between the casing body 13 and the cap attachment portion 14 on the inner surface, and they are flush with each other. The inner surface of the casing tube portion 11 has two X-side inner surfaces facing each other on both sides in the X direction, two Y-side inner surfaces facing each other on both sides in the Y direction, and a bottom surface.

[0023] (Cylindrical body 13) The outline of the outer surface of the tubular body 13 in a cross section perpendicular to the axis Z is a substantially constant rectangle at the rear, but gradually becomes larger toward the front while remaining similar in shape to the rear. A stepped surface 13a is provided at the front end of the tubular body 13, and a cap attachment portion 14 extends forward of the stepped surface 13a.

[0024] (Cap attachment part 14) The outline of the outer surface of the cross section of the cap attachment part 14 perpendicular to the axis Z is similar to, but slightly smaller than, the front end of the tubular main body 13. The front end of the cap attachment part 14 is provided with a non-circular (rectangular in this embodiment) opening 14a through which the solid content 100 is dispensed.

[0025] The cap mounting portion 14 has two X-side outer surfaces 14X on both sides in the X direction and two Y-side outer surfaces 14Y on both sides in the Y direction. Each of the X-side outer surfaces 14X has a mounting portion-side rising protrusion 14x that extends in the Y direction and has a substantially triangular cross section in the ZX direction. Each of the Y-side outer surfaces 14Y has a mounting portion-side rising protrusion 14y that extends in the X direction and has a substantially triangular cross section in the ZY direction.

[0026] The mounting part side rising protrusion 14x and the mounting part side rising protrusion 14y have a gentle slope in which the height (distance from the outer surface of the cap mounting part 14) gradually increases from the front side to the rear side. The rear sides of the mounting part side rising protrusion 14x and the mounting part side rising protrusion 14y have a steep slope in which the height suddenly decreases from the front side to the rear side.

[0027] (Rear cylinder part 12) A circular hole is provided in the bottom surface of the cylindrical body 13, and the rear cylindrical portion 12 is connected to the outer periphery of the hole toward the rear. The rear cylindrical portion 12 has a large diameter portion 12a and a small diameter portion 12b extending rearward from the large diameter portion 12a.

[0028] A circumferentially extending annular tube-side locking rib 12c is formed on the inner surface of the rear end of the large-diameter portion 12a. A rear-facing sleeve-side engagement surface 12d is formed on the outer step between the large-diameter portion 12a and the small-diameter portion 12b. The inner surface of the small-diameter portion 12b serves as a sleeve-side airtight sealing surface 12e.

[0029] (Groove 16) Fig. 5 is an enlarged view of part A surrounded by a two-dot chain line in Fig. 4. An annular groove 16 is formed in the cylindrical body 13, extending rearward from a step surface 13a between the cylindrical body 13 and the cap attachment portion 14 along the entire circumference of the step surface 13a. The cross-sectional shape of the groove 16 shown in Fig. 5 (orthogonal to the circumferential direction in which the groove 16 extends) is approximately rectangular, but is not strictly rectangular, and the groove width D1 on the front side (opening side) is larger than the groove width D2 on the rear side (bottom side).

[0030] The groove 16 has two inner surfaces (side surfaces) facing each other and a bottom surface 16b. The two inner surfaces (side surfaces) include an inner inner surface 161 located on the inside and an outer inner surface 162 facing the inner inner surface 161 and located outside the inner inner surface 161. The inner inner surface 161 is substantially flush with the outer surface of the cap attachment portion 14.

[0031] In the cross section shown in FIG. 5, the straight line showing the outline of the inner inner surface 161 of the groove portion 16 is slightly inclined with respect to the axis Z (not shown in FIG. 5) in a direction in which the distance from the axis Z decreases toward the front (the left side in FIG. 5 decreases). The width of the seal body 30 in a direction perpendicular to the axis Z is constant. When the seal body 30 is disposed in the groove portion 16, the groove width D1 and the groove width D2 are larger than the width of the seal body in a direction perpendicular to the axis Z, and a gap of a distance d11 is formed between the inner inner surface 161 and the inner surface of the seal body 30 at the front side in the axis Z direction. Meanwhile, at the rear side in the axis Z direction, the inner surface of the seal body 30 is fitted with the inner inner surface 161.

[0032] Furthermore, the straight line defining the contour of the outer inner surface 162 of the groove 16 is slightly inclined with respect to the axis Z (not shown in FIG. 5) in a direction in which the distance from the axis Z increases toward the front (the left side rises in FIG. 5). When the seal body 30 is disposed in the groove 16, a gap of distance d12 is formed between the outer inner surface 162 and the outer surface of the seal body 30 at the front side in the direction of the axis Z, and a gap of distance d22 is formed between the outer inner surface 162 and the outer surface of the seal body 30 at the rear side in the direction of the axis Z, with d12 > d22. In other words, the gap is larger at the front side than at the rear side.

[0033] Due to this relationship, when the seal body 30 is not compressed, the inner surface of the seal body 30 fits into the inner surface of the bottom side of the groove 16 and is fixed within the groove 16, while the outer surface of the seal body 30 is not fixed. The inner surface of the seal body 30 is not fixed to the inner surface of the opening side of the groove 16. Therefore, when the seal body 30 is not compressed, the seal body 30 is fixed on the bottom side of the groove portion 16, and the seal body 30 is not fixed on the opening side of the groove portion 16.

[0034] In the embodiment, the cross-sectional shape of the seal body 30 is rectangular, and the width in the direction perpendicular to the axial Z direction is constant, so that a gap is formed between the seal body 30 and the groove portion 16, but this is not limiting, and the cross-sectional shape of the seal body does not have to be rectangular. For example, by changing the width of the seal body in the direction perpendicular to the axial Z direction or by forming ribs or steps extending in the axial Z direction in the groove portion, it is possible to create a state in which "the seal body 30 is fixed at the bottom side of the groove portion 16 when not compressed, and is not fixed at the opening side of the groove portion 16."

[0035] A rib portion 16r that protrudes forward in the direction of axis Z is provided around the entire circumference on the bottom surface 16b of the groove portion 16. The rib portion is not limited to being provided on the bottom surface 16b of the groove portion 16, and may be provided on the bottom surface of the seal body 30.

[0036] (Holding body 40) The holder 40 is a cylindrical member with a substantially rectangular cross section and a bottom, as shown in Fig. 4. The holder 40 is placed inside the cylindrical storage portion 11 while holding the rear of the solid contents 100. The cross-sectional shape of the outer surface of the holder 40, perpendicular to the axis Z, is substantially the same as the cross-sectional shape of the inner surface of the cylindrical storage portion 11. A through-threaded hole 41 is formed in the bottom, into which a shaft threaded portion 53, described below, is inserted and screwed.

[0037] (Cap body 20) The cap body 20 is a rectangular tubular member with a closed front end, and its inner surface in a cross-sectional shape perpendicular to the axis Z is approximately the same shape as the outer surface of the cap mounting portion 14, and it can be inserted into and removed from the cap mounting portion 14 in the direction of the axis Z (without relative rotation).

[0038] The cap body 20 has two cap X-side inner surfaces 20X on both sides in the X direction and two cap Y-side inner surfaces 20Y on both sides in the Y direction. Each of the cap X-side inner surfaces 20X has a cap-side rising convex portion 20x extending in the Y direction and having a substantially triangular cross section in the ZX direction. Each of the cap Y-side inner surfaces 20Y has a cap-side rising convex portion 20y extending in the X direction and having a substantially triangular cross section in the ZY direction. The cap-side rising convex portions 20x and 20y have a gentle slope in which the height (distance from the inner surface of the cap body 20) gradually increases from the rear side to the front side. The front sides of the cap-side rising convex portions 20x and 20y have a steep slope in which the height suddenly decreases from the rear side to the front side.

[0039] The cap side rising protrusions 20x and 20y are located behind the positions of the mounting part side rising protrusions 14x and 14y formed on the outer surface of the cap mounting part 14 when the cap body 20 is mounted on the cap mounting part 14, and are formed at positions where the steep slopes of the cap side rising protrusions 20x and 20y face and abut against the steep slopes of the mounting part side rising protrusions 14x and 14y.

[0040] The rear end (opening side) of cap body 20 has a double protrusion, inward and outward, around the entire outer periphery. The inner protrusion is cap abutment portion 21 that abuts against seal body 30. The outer protrusion is cap covering portion 22 that fits into notch 13b on the outside of groove portion 16.

[0041] The cap abutment portion 21 is a protrusion provided around the entire outer periphery of the cap body 20, protruding rearward in the axial Z direction. When the cap body 20 is attached to the cap attachment portion 14, the cap abutment portion 21 abuts against the planar abutment surface 31 of the seal body 30 disposed in the groove portion 16, and compresses the abutment surface 31 in the axial Z direction (the longitudinal direction of the cross section of the seal body 30).

[0042] The cap covering portion 22 surrounds the outside of the cap abutting portion 21 and protrudes further in the axial Z direction than the cap abutting portion 21. When the cap body 20 is attached to the cap attachment portion 14, the cap covering portion 22 fits into a notch 13b provided around the entire periphery on the outside of the front side of the cylindrical main body 13.

[0043] (Seal body 30) The seal body 30 is disposed inside the annular groove 16 and is an annular elastic member that is a separate component from the tubular housing 11 and the cap body 20. The material of the seal body 30 is not particularly limited as long as it is an elastic material with excellent sealing performance. For example, thermoplastic elastomers such as olefin-based, polyester-based, vinyl chloride-based, styrene-based, polyamide-based, urethane-based, and 1,2-polybutadiene-based elastomers, synthetic rubbers such as butyl rubber, and natural rubbers can be used.

[0044] The Shore A hardness of the seal body 30 is preferably A60 or less because if it is greater than A60, the repulsive force is large, making it difficult to fit the cap body 20 and easy to remove it.

[0045] The seal body 30 has a substantially rectangular cross section (perpendicular to the circumferential direction in which the seal body 30 extends) as shown in Fig. 5. The seal body 30 is disposed in the groove portion 16 so that the longitudinal direction of the rectangular cross section is parallel to the axial Z direction. The front flat surface of the seal body 30 is the abutment surface 31 that abuts against the cap abutment portion 21, and the longitudinal direction of the seal body 30 in the cross section shown in Fig. 5 is the direction in which it is compressed by the cap abutment portion 21.

[0046] The circumferential length of the inner surface of the seal body 30 before being placed in the groove 16 is longer than the circumferential length of the front side of the inner inner surface 161 of the groove 16 and shorter than the circumferential length of the rear side. Therefore, when the seal body 30 is placed in the groove 16, the seal body 30 stretches on the rear (bottom) side of the groove 16, and the inner surface of the seal body 30 fits into the inner inner surface 161 of the groove 16. On the other hand, on the front (opening) side of the groove 16, a gap is formed between the seal body 30 and the inner inner surface 161 of the groove 16.

[0047] Furthermore, the circumferential length of the outer surface of the seal body 30 is shorter than the circumferential length of the outer inner surface 162 of the groove 16, both on the front and rear sides. Therefore, when the seal body 30 is disposed in the groove 16, a gap is formed between the seal body 30 and the outer inner surface 162 of the groove 16, both on the rear and front sides of the groove 16.

[0048] Strictly speaking, a portion of the front end of the seal body 30, including the contact surface 31, slightly protrudes outside the groove portion 16, but the rest of the seal body 30 is disposed within the groove portion 16. In other words, almost the entire surface of the seal body 30, except for the contact surface 31, is disposed within the groove portion 16.

[0049] (Shaft 50) The shaft body 50 has a shaft bottom 51 that covers the rear end of the grip body 60, a shaft base 52 that extends forward from the shaft bottom 51, and a shaft screw portion 53 that extends forward from the shaft base 52 into the inside of the accommodating tube portion 11 and is screwed into the through screw hole 41 of the holding body 40.

[0050] The shaft bottom portion 51 is a rectangular plate-like member, and a shaft bottom wall portion 51a is provided on the outer periphery of the shaft bottom portion 51, extending a certain distance forward in the axial Z direction. The shaft bottom wall portion 51a covers the entire length of the two short sides of the shaft bottom portion 51 extending in the Y direction and approximately one-third of the short sides on both sides of the two long sides extending in the X direction. In other words, the shaft bottom wall portion 51a is provided on the outer periphery of the shaft bottom portion 51 except for approximately one-third of the central portions of the long sides.

[0051] The shaft base 52 protrudes forward from the center of the shaft bottom 51. The shaft base 52 is comprised of a cylindrical shaft base rear portion 52a of approximately constant diameter from rear to front, a shaft base inclined portion 52b that extends forward from the shaft base rear portion 52a, gradually reduces in diameter, and then continues to extend forward at a constant diameter from there, and a shaft base front portion 52c that is provided in front of the shaft base inclined portion 52b, has a larger diameter than the front end of the shaft base inclined portion 52b, and then gradually reduces in diameter again from there. A rear-facing shaft-side locking surface 52d is formed on a step provided on the outer surface between the shaft base inclined portion 52b and the shaft base front portion 52c.

[0052] The shaft thread portion 53 is a long, thin rod-shaped member extending from the shaft base portion 52 toward the front, and shaft body side stopper ribs 53a are formed in two places on the outer periphery of the base of the rear end of this shaft thread portion 53. The outer periphery of the shaft thread portion 53 forward of the part where the shaft body side stopper rib 53a is formed is threaded.

[0053] When the holder 40 moves rearward in the direction of axis Z due to rotation of the shaft 50, the holder-side stopper rib 42 provided on the bottom surface of the holder 40 comes into contact with the shaft-side stopper rib 53a, thereby restricting the relative rotation between the holder 40 and the shaft 50 and preventing the holder 40 from moving rearward in the direction of axis Z.

[0054] (Grip body 60) Grip body 60 is disposed on the rear side of housing tubular portion 11, outside shaft base 52 of shaft body 50. Grip body 60 comprises a grip outer tubular portion 61 having a rectangular cross section, a grip inner tubular portion 63 disposed inside grip outer tubular portion 61, and a grip front wall portion 62 covering the front end between grip outer tubular portion 61 and grip inner tubular portion 63. Shaft base 52 is disposed inside grip inner tubular portion 63.

[0055] The grip body 60 further has a grip annular convex portion 64 that protrudes toward the inner diameter from the rear end of the grip inner cylindrical portion 63, and a grip plate-shaped rib 65 that extends rearward from the rear surface of the grip front wall portion 62 along the inner surface of the grip outer cylindrical portion 61, and a grip rear end opening 66 is provided at the rear end of the grip outer cylindrical portion 61.

[0056] The shaft base 52 of the shaft body 50 is disposed inside the grip inner cylindrical portion 63, and the shaft thread portion 53 is threaded into the through-hole 41 of the holder 40 inside the tubular housing portion 11 and extends further forward to the inside of the solid contents 100 held by the holder 40. The shaft bottom portion 51 fits into the grip rear end opening 66, and the shaft bottom wall portion 51a provided on the shaft bottom portion 51 abuts against the inner surface of the grip outer cylindrical portion 61. This connects the shaft body 50 and the grip body 60 and allows them to rotate together.

[0057] 4, the front surface of the grip annular protrusion 64 of the grip body 60 abuts against the sleeve-side engagement surface 12d of the sleeve body 10, so that forward movement of the grip body 60 is restricted by the sleeve body 10. Also, the rear end surface of the grip plate-like rib 65 abuts against the front end surface of the shaft bottom wall portion 51a of the shaft body 50, so that rearward movement of the grip body 60 is restricted by the shaft body 50. In other words, by sandwiching the grip body 60 between the sleeve body 10 and the shaft body 50, the position of the grip body 60 in the direction of axis Z is restricted.

[0058] (locking structure) The front surface of the tube-side locking rib 12c of the sleeve body 10 abuts against and locks onto the shaft-side locking surface 52d of the shaft body 50. In the embodiment, this locking structure between the sleeve body 10 and the shaft body 50 is provided inside the grip body 60 in the axial Z direction. Furthermore, in the embodiment, the locking structure is provided on the radially inner side of the grip outer tube portion 61 of the grip body 60 in a cross section perpendicular to the axial Z direction. This locking structure restricts the sleeve body 10 from moving forward relative to the shaft body 50.

[0059] Furthermore, since the sleeve-side engagement surface 12d of the sleeve body 10 abuts against the front surface of the grip annular projection 64 of the grip body 60, the grip body 60 restricts rearward movement of the sleeve body 10.

[0060] Because the shaft bottom wall portion 51a of the shaft body 50 abuts against the grip plate-like rib 65 of the grip body 60, forward movement of the shaft body 50 is restricted by the grip body 60. Furthermore, in the above-mentioned locking structure, the shaft-side locking surface 52d of the shaft body 50 abuts against the front surface of the tube-side locking rib 12c of the sleeve body 10, so rearward movement of the shaft body 50 is restricted by the sleeve body 10.

[0061] As a result of the above, the positions of the grip body 60, sleeve body 10 and shaft body 50 in the direction of axis Z are fixed, and the dispensing container 1 is maintained in the assembled state shown in FIG.

[0062] (Attaching the cap body 20 to the cap attachment portion 14) When the cap body 20 is placed over the cap attachment portion 14 and slid backward, the gentle slopes of the cap-side rising protrusions 20x and 20y of the cap body 20 climb up the gentle slopes of the attachment-part-side rising protrusions 14x and 14y of the cap attachment portion 14. Once they pass this gentle slope, the cap-side rising protrusions 20x and 20y fall along the steep slopes of the attachment-part-side rising protrusions 14x and 14y, and at this time, a change occurs in the force with which the user presses the cap body into the cap attachment portion 14, providing a clicking sensation (the feeling that the cap body 20 has fitted) and simultaneously causing the cap body 20 to fit into the cap attachment portion 14.

[0063] (First airtight structure A) The dispensing container 1 of this embodiment has a first airtight structure A composed of a seal body 30, a cap abutment portion 21, and a groove portion 16. When the cap body 20 is attached to the cap attachment portion 14, in the first airtight structure A, the cap abutment portion 21 abuts against a planar abutment surface 31 of the seal body 30 arranged in the groove portion 16, compressing the abutment surface 31 in the longitudinal direction (axis Z direction).

[0064] As described above, on the inner surface side of the seal body 30, at the rear side in the axial Z direction, the inner inner surface 161 of the groove portion 16 is fitted into the inner surface of the seal body 30. As a result, the seal body 30 is held relative to the groove portion 16, i.e., the sleeve body 10.

[0065] Additionally, a rib portion 16r is provided around the entire circumference of the bottom surface 16b of the groove portion 16, protruding forward in the direction of axis Z. When the seal body 30 is placed in the groove portion 16, the rear surface of the seal body 30 comes into contact with and is pressed against the rib portion 16r. This allows the seal body 30 to be in close contact with the groove portion 16, i.e., the sleeve body 10, thereby maintaining airtightness between the seal body 30 and the sleeve body 10.

[0066] In this embodiment, the rear side (bottom surface) of the seal body 30 is flat and a rib portion 16r is provided in the groove portion 16, but unlike this embodiment, a rib portion may be provided on the seal body and the bottom surface of the groove may be flat.

[0067] Meanwhile, on the outer surface side of the seal body 30, at the front side in the axial Z direction (the opening side of the groove portion 16), a gap of distance d12 is formed between the outer inner surface 162 of the groove portion 16 and the outer surface of the seal body 30. Further, at the front side in the axial Z direction, a gap of distance d11 is formed between the inner inner surface 161 of the groove portion 16 and the inner surface of the seal body 30.

[0068] When the cap body 20 is attached to the cap attachment portion 14, the cap abutment portion 21 longitudinally compresses the abutment surface 31 of the seal body 30 arranged in the groove portion 16. At this time, the seal body 30 is not fixed on the front side (opening side) of the groove portion 16, and gaps are provided between the seal body 30 and the inner inner surface 161 and outer inner surface 162 of the groove portion 16. Therefore, the seal body 30 can be sufficiently elastically deformed in a direction perpendicular to the axial Z direction, which is the direction in which the cap body 20 is opened and closed, and the casing cylindrical portion 11 is kept airtight.

[0069] When the seal body 30 is not compressed, it is preferable that the length in the axial Z direction of the unfixed portion of the seal body 30 (the portion on the front side (opening side) of the seal body 30 that is not in contact with the sleeve body 10) is equal to or greater than the length by which the seal body 30 is compressed in the axial Z direction by the cap body 20 (the length in the axial Z direction of the seal body 30 before compression minus the distance in the axial Z direction between the rib portion 16r and the cap abutment portion 21 when the cap body 20 is attached to the cap attachment portion 14).

[0070] Unlike the embodiment, if there is no gap between the side surface of the seal body and the inner and outer inner surfaces of the groove, and the direction perpendicular to the axial Z direction is constrained by the inner and outer inner surfaces of the groove, the seal body will be less likely to deform in the direction perpendicular to the axial Z direction. In this case, a large force is required to press the seal body in the axial Z direction with the cap abutment portion. Furthermore, if the seal body is deformed with a large force, the repulsive force of the seal body will also be large.

[0071] As a result, in a riding-up fitting method, as in the embodiment, in which the cap body is attached to the cap attachment part by the cap-side riding-up convex portion riding up on the attachment-part-side riding-up convex portion, the cap body is easily detached from the cap attachment part. If the fitting force is increased to prevent detachment, the cap body cannot be easily attached or detached by hand. While it is possible to attach the cap using a screw fitting or other method instead of the riding-up fitting method, it is difficult from a design perspective to use a screw fitting to fit the non-circular cap body and the tubular accommodating part. Furthermore, using a screw fitting makes the attachment and detachment process less easy than with the riding-up fitting method as in the embodiment. Furthermore, with a screw fitting, the seal body is easily worn due to friction with the cap body, reducing the durability of the dispensing container 1.

[0072] However, according to the first airtight structure A of the embodiment, a gap is provided between the inner inner surface 161 and the outer inner surface 162 of the groove portion 16 and the seal body 30 at the front side of the groove portion 16, so that the seal body 30 can easily elastically deform in a direction perpendicular to the axial Z direction compared to when no gap is provided.

[0073] Therefore, when attaching the cap body 20, the force with which the cap abutment portion 21 presses the seal body 30 may be small. In addition, the repulsive force of the seal body 30 against the cap body 20 when the cap body 20 is attached is also weak. For this reason, the fitting force of the cap body 20 to the cap attachment portion 14 does not need to be very strong. This makes it possible to attach the cap body using a riding-up fitting method in which the cap-side riding-up convex portion 20x and the cap-side riding-up convex portion 20y on the inner surface of the cap body 20 ride up the gentle slopes of the attachment-part-side riding-up convex portion 14x and the attachment-part-side riding-up convex portion 14y of the cap attachment portion 14. As a result, the seal body 30 is not rubbed by the cap body 20, so it is less likely to wear, improving the durability of the dispensing container 1.

[0074] Furthermore, when the cap body 20 is attached to the cap attachment part 14, the steep slopes of the cap-side rising convex parts 20x and 20y and the steep slopes of the attachment part-side rising convex parts 14x and 14y are formed in positions where they abut against each other. With this configuration, the cap body 20 can be well positioned relative to the sleeve body 10 in the axial Z direction, and the cap abutment parts 21 of the cap body 20 can compress the seal body 30 in the longitudinal direction with high precision.

[0075] In the case of a dispensing container, in the case of an airtight structure in which a commonly used cap body is elastically deformed and attached to the cap attachment portion of the storage tube, if the cap body and the storage tube are not perfectly circular, it is difficult to evenly deform and tightly fit the cap body around the entire circumference, making it difficult to maintain airtightness.

[0076] However, the first airtight structure A of the embodiment is not an airtight structure formed by elastically deforming the cap body and attaching it to the cap mounting portion, but rather a structure in which the seal body 30 is placed in the groove portion 16, and the cap abutment portion 21 provided on the cap body 20 presses the seal body 30.

[0077] Therefore, even if the cap body 20 and the cylindrical storage portion 11 are not perfectly circular, sufficient airtightness can be ensured between the cap body 20 and the cylindrical storage portion 11. Therefore, as in the embodiment, the cross section of the solid content 100 can be rectangular, and the shape of the cylindrical storage portion 11 can also be rectangular.

[0078] In the past, if the contact area between the cap body and the cylindrical container was not circular, it was difficult to deform the cap body evenly around the entire circumference, making it difficult to maintain airtightness. For this reason, even if the cross section of the solid contents was square, the contact area between the cap body and the container was sometimes circular.

[0079] However, when the cross-sectional shape of the solid content is not a perfect circle, if the part of the cylindrical container that is in close contact with the cap body is made perfect circle and a solid glue with a non-perfect circle cross-section can be contained inside, the cross-sectional shape of the cylindrical container will be larger than the cross-sectional shape of the solid content. This difference is particularly noticeable when the cross-sectional shape of the solid content is not a regular polygon, but a rectangle, for example.

[0080] In contrast to this, in the dispensing container 1 of the embodiment, the shape of the tubular storage part 11 can also be made rectangular to match the shape of the solid content 100, which has a rectangular cross section. Therefore, there is no need to make the tubular storage part 11 larger than necessary compared to the solid content 100, and the dispensing container 1 does not become larger than necessary.

[0081] (Effects of the notch 13b and the cap covering portion 22) The cap covering portion 22 surrounds the outside of the cap abutting portion 21 and protrudes further in the axial Z direction than the cap abutting portion 21. When the cap body 20 is attached to the cap attachment portion 14, the cap covering portion 22 fits into a notch 13b that is provided around the entire periphery at the outermost part of the front end of the portion of the cylindrical main body 13 where the groove portion 16 is formed.

[0082] In this way, the opening of the groove 16 in which the seal 30 is disposed is covered by the cap covering portion 22, so that the seal 30 cannot be contacted from the outside, is protected from the outside, and can prevent deterioration of the seal 30. Furthermore, since the seal 30 is covered by the cap covering portion 22 and cannot be seen from the outside, it is also aesthetically pleasing.

[0083] Furthermore, because of the presence of the cap covering portion 22, even if the cap body 20 removed from the cap attachment portion 14 is placed on a desk, for example, with the rear side (opening side) facing downwards, the cap abutting portion 21 does not come into contact with the desk surface. Therefore, dust and the like are less likely to adhere to the cap abutting portion 21, reducing the risk that dust and the like will interfere with the airtightness of the seal body 30.

[0084] (Second airtight structure B) According to the embodiment, the rear cylindrical portion 12 of the sleeve body 10 is sandwiched between the grip inner cylindrical portion 63 of the grip body 60 and the shaft base portion 52 of the shaft body 50. The sleeve-side airtight surface 12e, which is the inner surface of the small diameter portion 12b of the rear cylindrical portion 12 of the sleeve body 10, is in close contact with the shaft-side airtight surface 52e, which is the outer surface of the shaft base rear portion 52a of the shaft base 52. The second airtight structure B, in which the sleeve-side airtight surface 12e and the shaft-side airtight surface 52e are in close contact with each other, ensures airtightness of the inside of the sleeve body 10 from the outside.

[0085] The sleeve body 10 has a large diameter portion 12a extending rearward in the axial Z direction from the rear end of the tubular accommodating portion 11 (rear end of the tubular main body 13), and a sleeve-side airtight forming surface 12e is located at the tubular-side locking rib 12c and the small diameter portion 12b. In other words, a second airtight structure B between the sleeve body 10 and the shaft body 50 is formed rearward in the axial Z direction from the rear end of the tubular accommodating portion 11 of the sleeve body 10, and is provided inside the grip body 60 in the axial Z direction. Furthermore, in the embodiment, the second airtight structure B is provided radially inward in a cross section of the grip outer tubular portion 61 of the grip body 60 that is perpendicular to the axial Z direction.

[0086] Therefore, in the embodiment, the second airtight structure B between the sleeve body 10 and the shaft body 50 and the above-mentioned locking structure are both formed rearward in the axial Z direction from the rear end of the tubular main body 13 of the sleeve body 10, and are provided inside the grip body 60 in the axial Z direction.

[0087] Conventionally, the locking structure and airtight structure between the sleeve body and the shaft body have been provided inside the tubular body 13 forward of the rear end of the tubular body 13 of the sleeve body 10 and forward of the grip body. In this case, the dispensing container as a whole becomes longer in the axial Z direction.

[0088] However, in the embodiment, the second airtight structure B between the sleeve body 10 and the shaft body 50, which is formed by the close contact between the sleeve side airtight surface 12e and the shaft side airtight surface 52e, is provided inside the portion in the axial Z direction where the grip body 60 is disposed. Therefore, the length of the dispensing container 1 can be shortened, and the dispensing container 1 can be made more compact than in the conventional structure without reducing the amount of solid content 100.

[0089] Furthermore, the locking structure between the sleeve body 10 and the shaft body 50 is provided inside the portion in the direction of the axis Z where the grip body 60 is located, thereby making it possible to make the dispensing container 1 even more compact.

[0090] By inserting the shaft body 50 into the rear cylindrical portion 12 of the sleeve body 10, the sleeve side airtight forming surface 12e and the shaft side airtight forming surface 52e come into close contact to form a tightly sealed structure, making it possible to realize an airtight structure with easy assembly.

[0091] (Extraction operation) From the state shown in FIG. 4, the cap body 20 is removed from the tubular housing portion 11 of the sleeve body 10, and the grip body 60 is rotated while holding the tubular housing portion 11. This causes the shaft body 50 to rotate integrally with the grip body 60. The outer shape of the holder 40 engages with the inner shape of the tubular housing portion 11 of the sleeve body 10, and the holder 40 does not rotate relative to the sleeve body 10. When the shaft body 50 rotates, the holder 40, which is threadedly engaged with the axial thread portion 53 of the shaft body 50, moves in the axial Z direction. As the holder 40 moves forward in the axial Z direction, the solid contents 100 held by the holder 40 are dispensed forward in the axial Z direction.

[0092] After the solid contents 100 are dispensed, when the grip body 60 is rotated in the opposite direction to that used for dispensing, the holding body 40 moves rearward in the axial Z direction, and the solid contents 100 are returned into the storage tube portion 11.

[0093] (Removal of the cap body 20 from the cap attachment portion 14) By holding the sleeve body 10 or the grip body 60 and pulling the cap body 20 forward, the cap body 20 can be removed from the accommodating cylindrical portion 11 of the sleeve body 10 (without relative rotation).

[0094] When the grip body is held to remove the cap body 20 from the sleeve body 10, a force is applied that moves the sleeve body 10 forward along with the cap body 20. At this time, the large diameter portion 12a of the sleeve body 10 abuts against the shaft-side locking surface 52d of the shaft body 50. The shaft-side locking surface 52d and the large diameter portion 12a abut against each other at surfaces that are approximately perpendicular to the axial Z direction, so they are structured to not easily come off. Therefore, even if the sleeve body 10 is pulled, it will not come off the shaft body 50. Furthermore, because the sleeve body and the shaft body 50, which hold the grip body 60, do not move relative to each other in the axial Z direction, the grip body 60 and the sleeve body 10 will not separate.

[0095] (Other effects of the dispensing container 1) The outer peripheral shape of the front end of grip body 60 is approximately the same as the outer peripheral shape of the rear end of tubular casing 11 of sleeve body 10. Therefore, there is no step between the rear end of tubular casing 11 of sleeve body 10 and the front end of grip body 60, so grip body 60 and sleeve body 10 are integrated, improving the aesthetic appearance of dispensing container 1.

[0096] Since the grip front wall portion 62 perpendicular to the Z-axis direction is provided on the front side of the grip body 60, foreign matter is less likely to enter the inside of the grip body 60 even when the grip body 60 is rotated.

[0097] Furthermore, the grip body 60 has excellent durability because there are no portions that are engaged with other members through deformation, such as press fitting.

[0098] The seal body 30 is preferably a separate part from the tubular housing portion 11 and the cap body 20. Unlike the embodiment, the seal body may be manufactured as an integral part with, for example, the tubular housing portion or the cap body using insert molding or two-color molding. In this case, however, the shape of the tubular housing portion or the cap body is limited, the manufacturing process becomes complicated, and manufacturing is not easy. Furthermore, when the seal body and the accommodating tube portion or the cap body are integrally molded by insert molding or two-color molding, in order to provide a gap between the inner surface of the groove portion and the seal body, it is necessary to form the gap by using the thickness of the mold, which results in a larger gap than necessary and a larger shape.

[0099] However, in the embodiment, the sealing body 30 is easy to manufacture because it is a separate part from the tubular accommodating portion 11 and the cap body 20. Furthermore, the gap between the groove portion 16 and the sealing body 30 can be made appropriately small, allowing the dispensing container 1 as a whole to have a compact shape.

[0100] Almost the entire surface of the seal body 30, except for the contact surface 31 that contacts the cap body 20, is disposed within the groove portion 16. This reduces the possibility that the user will come into contact with the seal body 30, thereby preventing deterioration of the seal body 30.

[0101] The shape of the seal body 30 is preferably symmetrical with respect to an axis perpendicular to the axis Z. This eliminates the need for directionality in the front-rear direction when assembling the seal body 30 into the groove portion 16, improving assembly efficiency.

[0102] Although the preferred embodiment of the present invention has been described above, the present invention is not limited thereto and various modifications are possible. For example, in the embodiment, the first airtight structure A is provided between the cap body 20 and the sleeve body 10 (cap mounting portion 14) which have a substantially rectangular cross section. However, the present invention is not limited thereto and may be provided between the cap body and the sleeve body (cap mounting portion) which have a cross section other than rectangular.

[0103] In addition, in the embodiment, the groove portion 16 is provided on the front side of the accommodating cylindrical portion 11, and the abutment portion 21 is provided on the cap body 20, but this is not limited to this, and an annular groove portion may be provided on the rear side of the cap body so as to open in the axial direction, and the abutment portion may be provided on the front side of the accommodating cylindrical portion.

[0104] In the embodiment, the cap covering portion 22 is provided on the cap body 20 , but is not limited to this and may be provided on the tubular housing portion 11 .

[0105] In the embodiment, in the cross section shown in Fig. 5, the contact surface 31 of the seal body 30 arranged in the groove portion 16 is flat and perpendicular to the axis Z, but the contact surface may be flat and inclined relative to the plane perpendicular to the axis Z. By making the contact surface flat and inclined, even if glue or the like adheres to the contact surface of the seal body, it is possible to prevent the cap contact portion 21 and the seal body 30 from sticking together via the glue or the like. In particular, it is preferable that the contact surface be flat and inclined rearward outward from the axis Z. The contact surface is not limited to a flat surface, but may be a curved surface.

[0106] Furthermore, the first airtight structure between the sleeve body and the cap body is not limited to the configuration of the first airtight structure A of the embodiment. For example, the cross sections of the cap body and the cap attachment part may both be circular, and the cap body may be elastically deformed and attached to the cap attachment part of the tubular accommodating part without using a seal body, thereby forming an airtight structure of a riding-up fitting type.

[0107] In the embodiment, the grip body 60 and the shaft body 50 are separate parts, but they may be connected as a single part. From the standpoint of ease of manufacturing, it is preferable to have the grip body 60 and the shaft body 50 as separate parts. [Explanation of symbols]
