Description

Technical Field

[0001] The present invention relates to a feeding container.

Background Art

[0002] There is a feeding container in which a solid paste is stored as a solid content in a cylindrical storage portion and the solid paste is fed out and used. Since the solid paste hardens when dried and becomes unusable or its quality deteriorates, it is important to maintain the airtightness inside the feeding container with the cap body attached.

[0003] As a method of attaching a cap body with airtightness maintained, there is a riding fit method in which a convex portion provided on the outer periphery of the storage portion is ridden on while the cap body is deformed. Since the attachment and detachment of the cap body are easier compared to the screw fitting method, it is widely used. When the storage portion and the cap body are cylindrical in the riding fit method, when the cap body is attached to the storage portion, the cap body deforms evenly in the circumferential direction, so the airtightness is relatively easy to maintain.

[0004] On the other hand, for example, from the viewpoint of ease of painting on corners, etc., a solid paste having a prismatic shape may be desired. When the solid paste has a prismatic shape, it is common for the storage portion and the cap body to also have a square tube shape. Further, if the feeding container as a whole has a prismatic shape, it is easy to put it into a pen case or the like and it is not easy to roll on a desk.

[0005] However, when the storage portion and the cap body have a square tube shape, when the cap body is attached to the storage portion, the cap body does not deform evenly in the circumferential direction, and sufficient airtightness cannot be obtained.

[0006] For this reason, for example, Patent Document 1 discloses a technique in which the cross-sectional shape of the solid paste is non-circular, but the contact portion between the cap body and the storage portion is circular. However, according to this technique, when storing a solid paste having a square cross-section inside and making the airtight portion with the cap body circular, the cross-sectional shape of the feeding container becomes larger than the cross-sectional shape of the solid paste.

Summary of the Invention

Problems to be Solved by the Invention

[0008] The present invention provides a dispensing container that houses solid contents therein and includes a non-circular cross-section accommodating cylinder portion and a cap body, is capable of being miniaturized while ensuring airtightness between the cap body and the accommodating cylinder portion, and is easy to attach and detach the cap body.

Means for Solving the Problems

[0009] (1) To solve the above problems, the present invention provides a dispensing container comprising: an inner non-circular cross-section accommodating cylinder portion capable of accommodating solid contents and having a cylinder portion opening through which the solid contents are dispensed provided on the front side; a cap body axially insertable and removable with respect to the accommodating cylinder portion and capable of opening and closing the cylinder portion opening; a groove portion annularly provided on one of the accommodating cylinder portion or the cap body and opening in the axial direction; and a seal body disposed in the groove portion. When the cap body is attached to the accommodating cylinder portion, the seal body abuts against a contact portion provided on the other of the accommodating cylinder portion or the cap body and is compressed in the axial direction, thereby maintaining airtightness between the cap body and the accommodating cylinder portion.

[0010] (2) The seal body may be disposed in the groove portion except for a contact surface that abuts against the other of the accommodating cylinder portion or the cap body.

[0011] (3) The longitudinal direction in a cross-section in a direction orthogonal to the circumferential direction of the seal body may be a direction in which the seal body is compressed in a state of being disposed in the groove portion.

[0012] (4) The sealing body may not be fixed at the opening side within the groove portion in a non-compressed state.

[0013] (5) The other one of the housing cylinder portion or the cap body may have a protruding portion protruding axially outward of the contact portion.

[0014] (6) The contact surface that contacts the contact portion on the sealing body may be a plane perpendicular to the axis.

[0015] (7) The contact surface that contacts the contact portion on the sealing body may be inclined with respect to the plane perpendicular to the axis.

[0016] (8) The contact surface may be inclined such that the side closer to the inner surface of the sealing body protrudes more than the side closer to the outer surface.

[0017] (9) A rib portion extending in the circumferential direction and protruding in the axial direction may be provided on the bottom surface of the sealing body or the groove portion.

[0018] (10) On the cap side surface of the cap body, a cap side riding convex portion having a cap body gentle slope on the cap opening side and a cap body steep slope on the opposite side is formed. When the cap body is mounted on the housing cylinder portion, on the cylinder portion side surface facing the cap side surface, a cylinder portion side riding convex portion having a cylinder portion gentle slope on the cylinder portion opening side and a cylinder portion steep slope on the opposite side is formed. When the cap body is mounted on the housing cylinder portion, the cap body gentle slope slides on the cylinder portion gentle slope and the cap body moves in the axial direction with respect to the housing cylinder portion. When the cap side riding convex portion gets over the cylinder portion side riding convex portion, the cap body steep slope and the cylinder portion steep slope may contact each other.

[0019] (11) The inclination angle of the cap body gentle slope with respect to the axis may be smaller than that of the cap body steep slope.

Advantages of the Invention

[0020] According to the present invention, there is provided a dispensing container that includes a receiving cylinder portion with a non-circular cross-section for accommodating solid contents therein and a cap body, and that can be miniaturized while ensuring airtightness between the cap body and the receiving cylinder portion, and is easy to attach and detach the cap body.

Embodiments for Carrying Out the Invention

[0022] (First Embodiment) Hereinafter, the feeding container 1 of the first embodiment of the present invention will be described. The feeding container 1 is a container that houses the solid content 100 therein and can feed out the solid content 100 in a required amount for use. Hereinafter, the side from which the solid content 100 is fed out will be referred to as the front, the opposite side as the rear, and the feeding direction (front-rear direction) will be described as the Z-axis direction. Note that the feeding container 1 has a substantially rectangular cross-section in a direction orthogonal to the feeding direction, and the axis Z passes through the center of the substantially rectangular cross-section. In addition, when explaining each member of the feeding container 1, when viewed in a cross-section orthogonal to the axis Z, the side on the axis Z side will be described as the inner side and the opposite side as the outer side.

[0023] FIG. 1 is a perspective view of the feeding container 1 of the first embodiment as viewed obliquely from the front. FIG. 2 is an exploded perspective view of the feeding container 1 of the first embodiment as viewed obliquely from the front. FIG. 3 is an exploded perspective view of the feeding container 1 of the first embodiment as viewed obliquely from the rear. FIG. 4 is an XZ cross-sectional view at the center in the Y-axis direction in FIG. 1 of the feeding container 1 of the first embodiment. Note that in FIGS. 2 and 3, the description of the solid content 100 is omitted.

[0024] (Solid Content 100) FIG. 4 shows the solid content 100 housed in the feeding container 1. The solid content 100 is, for example, a solid paste that has a substantially rectangular cross-section that is not square and is substantially a rectangular parallelepiped as a whole, with the rear side held by the holding body 40 described later. However, the cross-sectional shape of the solid content 100 is not limited to this, and any non-circular shape may be used, such as a substantially elliptical shape, or a quadrangular shape such as a square, rhombus, or a polygonal shape such as a triangular shape or a pentagonal shape (including the so-called polygonal shape of a rouleau). In addition, the solid content 100 may be other than solid paste, such as cosmetics such as foundation, lipstick, and lip cream, or solid drawing materials such as crayons.

[0025] Here, when the cross-sectional shape perpendicular to the axis Z of the solid content 100 is substantially rectangular, it is easier to apply the coating to the corners and the like compared to the case where the cross-sectional shape is circular. Also, compared to the case where the cross-sectional shape is square, the solid paste can be applied to the coating surface in either the direction of the wide width of the long side or the narrow width of the short side, so the coating width can be changed according to the application, and it is easy to use.

[0026] (Feeding container 1) The feeding container 1 is generally substantially rectangular parallelepiped, and the cross-sectional shape perpendicular to the axis Z is a substantially similar shape that is one size larger than the cross-sectional shape of the solid content 100, and the solid content 100 can be accommodated inside. Hereinafter, the long side direction of the rectangular cross-section will be described as the X direction, and the short side direction will be described as the Y direction.

[0027] The feeding container 1 includes a sleeve body 10, a cap body 20 detachably attached to the sleeve body 10, a seal body 30 disposed to maintain airtightness between the sleeve body 10 and the cap body 20, a holding body 40 that holds the solid content 100 (shown in FIG. 4) inside the sleeve body 10, a shaft body 50 that drives the holding body 40 and the solid content 100 in the axial direction of the axis Z, and a grip body 60 that covers the rear side of the shaft body 50. In the embodiment, the grip body 60 and the shaft body 50 are separate bodies, but they may be composed of a single part.

[0028] Further, the feeding container 1 has a first airtight structure A (shown in FIGS. 4 and 6 described later) including the seal body 30 between the sleeve body 10 and the cap body 20 provided on the front side of the feeding container 1, and a second airtight structure B (shown in FIG. 4) between the sleeve body 10 and the shaft body 50 provided on the rear side of the feeding container 1.

[0029] (Sleeve body 10) The sleeve body 10 has a housing cylinder portion 11 that houses the solid content 100, and a rear cylinder portion 12 that extends rearward from the housing cylinder portion 11.

[0030] (Housing cylinder portion 11) The housing cylinder part 11 houses the solid content 100 and the holding body 40 that holds the solid content 100 so as to be movable in the axial Z direction. The housing cylinder part 11 is a rectangular tube member with a substantially rectangular cross-sectional shape perpendicular to the axis Z, and includes a cylinder part main body 13 and a cap mounting part 14 extending forward from the cylinder part main body 13.

[0031] The inner surface of the housing cylinder part 11 has a substantially constant cross-sectional shape in the axial Z direction, and the shape of the present embodiment (the shape inside the cross-section of the housing cylinder part 11 perpendicular to the axis Z) is a non-circular substantially rectangle. That is, there is no step between the cylinder part main body 13 and the cap mounting part 14 on the inner surface, and they are flush. The inner surface of the housing cylinder part 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.

[0032] (Cylinder part main body 13) The outline of the outer surface in the cross-section of the cylinder part main body 13 perpendicular to the axis Z is a substantially constant rectangle at the rear part, but gradually becomes larger while remaining similar to the rear part as it goes forward. A stepped surface 13a is provided at the front end of the cylinder part main body 13, and the cap mounting part 14 extends forward from the stepped surface 13a.

[0033] (Cap mounting part 14) The outline of the outer surface of the cross-sectional shape of the cap mounting part 14 perpendicular to the axis Z is similar to the front end of the cylinder part main body 13, but is slightly smaller. A non-circular (rectangular in the embodiment) cylinder part opening 14a through which the solid content 100 is fed out is provided at the front end of the cap mounting part 14.

[0034] FIG. 5 is an enlarged view of the portion P surrounded by the two-dot chain line in FIG. 4. As shown in FIGS. 2, 3, and 5, the cap mounting portion 14 of the housing cylinder portion 13 has, on the outer surface, two cylinder portion side surfaces 14X on both sides in the X direction and two cylinder portion side surfaces 14Y on both sides in the Y direction. As shown in FIGS. 2, 3, and 5, on each of the cylinder portion side surfaces 14X, there is formed a cylinder portion side upward convex portion 14x having a predetermined width in the Y direction and a substantially triangular cross-sectional shape in the ZX direction. As shown in FIGS. 2 and 3, on each of the cylinder portion side surfaces 14Y, there is formed a cylinder portion side upward convex portion 14y having a predetermined width in the X direction and a substantially triangular cross-sectional shape in the ZY direction.

[0035] The cylinder portion side upward convex portion 14x and the cylinder portion side upward convex portion 14y each have a cylinder portion gentle slope 14G formed on the cylinder portion opening 14a side (front side in the figure) of the cap mounting portion 14 and a cylinder portion steep slope 14S formed on the opposite side (rear side in the figure). The cylinder portion gentle slope 14G of the cylinder portion side upward convex portion 14x is inclined at a substantially constant angle β1 with respect to the axis Z (showing a line Z' parallel to the axis Z in the figure) in the ZX cross-section as shown in FIG. 5, and the cylinder portion steep slope 14S of the cylinder portion side upward convex portion 14x is inclined at a substantially constant angle β2 with respect to the axis Z. The cylinder portion gentle slope 14G of the cylinder portion side upward convex portion 14y is inclined at a substantially constant angle β1 with respect to the axis Z in the ZY cross-section, and the cylinder portion steep slope 14S of the cylinder portion side upward convex portion 14y is inclined at a substantially constant angle β2 with respect to the axis Z. β1 < β2, and β2 preferably satisfies 15° ≤ β2 ≤ 30°.

[0036] (Rear cylinder portion 12) A circular hole is provided in the bottom surface of the cylinder portion main body 13, and the rear cylinder portion 12 is connected rearward from the outer periphery of the hole. The rear cylinder portion 12 has a large diameter portion 12a and a small diameter portion 12b extending rearward from the large diameter portion 12a.

[0037] An annular cylinder side locking rib 12c extending in the circumferential direction is formed on the inner surface of the rear end of the large diameter portion 12a. A sleeve side engaging surface 12d facing the rear side is formed on the outer step portion 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 forming surface 12e.

[0038] (Groove portion 16) FIG. 6 is an enlarged view of a portion Q surrounded by a two-dot chain line in FIG. 4. In the cylindrical body 13, an annular groove portion 16 extending over the entire circumference of the step surface 13a is formed rearward from the step surface 13a between the cylindrical body 13 and the cap mounting portion 14. The cross-sectional shape of the groove portion 16 shown in FIG. 6 (orthogonal to the circumferential direction in which the groove portion 16 extends) is substantially rectangular, but not a strict rectangle, and the groove width D1 on the front side (opening side) is larger than the groove width D2 on the rear side (bottom side).

[0039] The groove portion 16 has two inner surfaces (side surfaces) facing each other and a bottom surface 16b. The two inner surfaces (side surfaces) have an inner inner surface 161 located on the inner side 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 mounting portion 14.

[0040] In the cross-section shown in FIG. 6, the straight line indicating the contour of the inner inner surface 161 of the groove portion 16 is slightly inclined in a direction in which the distance from the axis Z (not shown in FIG. 6) decreases as going forward (the left side goes down in FIG. 6) with respect to the axis Z. The width of the seal body 30 in the direction orthogonal to the axis Z direction is constant. In a state where 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 the direction orthogonal to the axis Z direction, and a gap with a distance d11 is formed between the inner inner surface 161 and the inner surface of the seal body 30 on the front side in the axis Z direction. On the other hand, on the rear side in the axis Z direction, the inner surface of the seal body 30 is fitted with the inner inner surface 161.

[0041] Also, the straight line indicating the contour of the outer inner surface 162 of the groove portion 16 is slightly inclined in a direction in which the distance from the axis Z (not shown in FIG. 6) increases as going forward (the left side goes up in FIG. 6) with respect to the axis Z. In a state where the seal body 30 is disposed in the groove portion 16, a gap with a distance d12 is formed between the outer inner surface 162 and the outer surface of the seal body 30 on the front side in the axis Z direction, and a gap with a distance d22 is formed between the outer inner surface 162 and the outer surface of the seal body 30 on the rear side in the axis Z direction, and d12 > d22. That is, the gap is larger on the front side than on the rear side.

[0042] Due to such a relationship, in the uncompressed state, within the groove portion 16, the inner surface of the seal body 30 is fitted and fixed to the inner surface on the bottom surface side of the groove portion 16, and the outer surface of the seal body 30 is in an unfixed state. The inner surface of the seal body 30 is not fixed to the inner surface on the opening side of the groove portion 16. Therefore, in the uncompressed state, on the bottom surface side within the groove portion 16, the seal body 30 is fixed, and on the opening side within the groove portion 16, the seal body 30 is in an unfixed state.

[0043] In the embodiment, the cross-sectional shape of the seal body 30 is rectangular, and the width in the direction orthogonal to the axial Z direction is a constant width, thus forming a gap with the groove portion 16. However, it is not limited to this. The cross-sectional shape of the seal body may not be rectangular. For example, by changing the width of the seal body in the direction orthogonal to the axial Z direction, or by forming ribs or steps extending in the axial Z direction within the groove portion, the state of "in the uncompressed state, (on the bottom surface side within the groove portion 16, the seal body 30 is fixed,) on the opening side within the groove portion 16, the seal body 30 is in an unfixed state" may be formed.

[0044] On the bottom surface 16b of the groove portion 16, a rib portion 16r protruding forward in the axial Z direction is provided over the entire circumference. Note that the rib portion is not limited to the bottom surface 16b of the groove portion 16 and may be provided on the bottom surface of the seal body 30.

[0045] (Holder 40) The holder 40 is a bottomed cylindrical member with a substantially rectangular cross-section as shown in FIG. 4. The holder 40 is arranged inside the housing cylinder portion 11 while holding the rear of the solid content 100. The cross-sectional shape of the outer surface side of the holder 40 orthogonal to the axial Z is substantially the same as the cross-sectional shape of the inner surface of the housing cylinder portion 11. A through screw hole 41 is formed at the bottom, through which a shaft screw portion 53 described later is inserted and screwed.

[0046] (Cap body 20) The cap body 20 is a square tube member with a closed front end and a cap opening 20a at the rear end. In a cross-sectional shape perpendicular to the axis Z, the inner surface is substantially the same shape as the outer surface of the cap mounting portion 14 and can be inserted into and removed from the cap mounting portion 14 in the Z-axis direction (without relative rotation).

[0047] As shown in FIGS. 3 and 5, the cap body 20 has, on its inner surface, two cap side surfaces 20X on both sides in the X direction and two cap side surfaces 20Y on both sides in the Y direction. As shown in FIGS. 3 and 5, on each of the cap side surfaces 20X, a cap side upward convex portion 20x having a predetermined width in the Y direction and a substantially triangular cross-sectional shape in the ZX direction is formed. As shown in FIG. 3, on each of the cap side surfaces 20Y, a cap side upward convex portion 20y having a predetermined width in the X direction and a substantially triangular cross-sectional shape in the ZY direction is formed.

[0048] The cap side upward convex portion 20x and the cap side upward convex portion 20y each have a cap body gentle slope 20G formed on the cap opening 20a side (the rear side in the figure) and a cap body steep slope 20S formed on the opposite side (the front side in the figure). The cap body gentle slope 20G of the cap side upward convex portion 20x is inclined at a substantially constant angle α1 with respect to the axis Z (showing a line Z' parallel to the axis Z in the figure) in the ZX cross-section as shown in FIG. 5, and the cap body steep slope 20S of the cap side upward convex portion 20x is inclined at a substantially constant angle α2 with respect to the axis Z. The cap body gentle slope 20G of the cap side upward convex portion 20y is inclined at a substantially constant angle α1 with respect to the axis Z in the ZY cross-section, and the cap body steep slope 20S of the cap side upward convex portion 20y is inclined at a substantially constant angle α2 with respect to the axis Z. α1 < α2, and it is preferable that 15° ≤ α2 ≤ 30°. Also, it is preferable that α2 ≈ β2, and in the embodiment, α2 ≈ β2. In the embodiment, α1 ≈ β1, but it is not limited to this. And it is preferable that at least one of the angle α1 and the angle β1 is less than 15 degrees.

[0049] The cap-side mounting convex portions 20x and 20y are formed at positions behind the positions of the cylindrical portion-side mounting convex portions 14x and 14y formed on the outer surface of the cap mounting portion 14 when the cap body 20 is mounted on the cap mounting portion 14.

[0050] The end portion on the rear side (opening side) of the cap body 20 projects doubly inward and outward over the entire circumference of the outer periphery. The inner projecting portion is the cap contact portion 21 that contacts the seal body 30. The outer projecting portion is the cap covering portion 22 that enters the notch 13b outside the groove portion 16.

[0051] The cap contact portion 21 is a projecting portion provided to project rearward in the axial Z direction over the entire circumference of the outer periphery of the cap body 20. When the cap body 20 is mounted on the cap mounting portion 14, the cap contact portion 21 contacts the flat contact surface 31 of the seal body 30 disposed in the groove portion 16 and compresses the contact surface 31 in the axial Z direction (the longitudinal direction of the cross section of the seal body 30).

[0052] The cap covering portion 22 surrounds the outside of the cap contact portion 21 and projects longer than the cap contact portion 21 in the axial Z direction. When the cap body 20 is mounted on the cap mounting portion 14, the cap covering portion 22 enters the notch 13b provided over the entire circumference on the outer side of the front side of the cylindrical portion main body 13.

[0053] (Seal body 30) The seal body 30 is an annular elastic member disposed inside the annular groove portion 16 and is a separate component from the housing cylindrical portion 11 and the cap body 20. The material of the seal body 30 is not particularly limited as long as it is an elastic body having excellent sealing performance. For example, thermoplastic elastomers such as olefin-based, polyester-based, vinyl chloride-based, styrene-based, polyamide-based, urethane-based, 1,2-polybutadiene-based, etc., synthetic rubbers such as butyl rubber, natural rubber, etc. can be used.

[0054] The Shore A hardness of the sealing body 30 is preferably A60 or less. This is because if it is greater than A60, the repulsive force will be large, making it difficult to fit the cap body 20 and easy to come off.

[0055] The sealing body 30 has a substantially rectangular cross-sectional shape (orthogonal to the circumferential direction in which the sealing body 30 extends) as shown in FIG. 6. The sealing body 30 is arranged in the groove portion 16 such that the longitudinal direction of the rectangle in the cross-section is parallel to the axis Z direction. The front plane of the sealing body 30 is a contact surface 31 that contacts the cap contact portion 21, and the longitudinal direction of the sealing body 30 in the cross-section shown in FIG. 6 is the direction in which it is compressed by the cap contact portion 21.

[0056] The circumferential length of the inner surface of the sealing body 30 before being placed in the groove portion 16 is longer than the circumferential length of the front side of the inner inner surface 161 of the groove portion 16 and shorter than the circumferential length of the rear side. Therefore, when the sealing body 30 is arranged in the groove portion 16, on the rear (bottom) side of the groove portion 16, the sealing body 30 extends and the inner surface of the sealing body 30 fits with the inner inner surface 161 of the groove portion 16. On the other hand, on the front (opening) side of the groove portion 16, a gap is formed between the sealing body 30 and the inner inner surface 161 of the groove portion 16.

[0057] Also, the circumferential length of the outer surface of the sealing body 30 is shorter than the circumferential length of the outer inner surface 162 of the groove portion 16 both on the front side and the rear side. Therefore, when the sealing body 30 is arranged in the groove portion 16, gaps are formed between the sealing body 30 and the outer inner surface 162 of the groove portion 16 both on the rear side and the front side.

[0058] Strictly speaking, a part of the front end of the sealing body 30 including the contact surface 31 slightly protrudes outside the groove portion 16, but substantially the entire other part is arranged in the groove portion 16. That is, the surfaces of the sealing body 30 other than the contact surface 31 are arranged almost entirely in the groove portion 16.

[0059] (Shaft body 50) The shaft body 50 has a shaft bottom portion 51 that covers the rear end of the grip body 60, a shaft base portion 52 that extends forward from the shaft bottom portion 51, and a shaft screw portion 53 that extends forward from the shaft base portion 52 into the interior of the housing cylinder portion 11 and is screwed into the through screw hole 41 of the holding body 40.

[0060] The shaft bottom portion 51 is a rectangular plate-like member, and on this shaft bottom portion 51, a shaft bottom wall portion 51a that extends forward in a certain length in the shaft Z direction is provided on the outer periphery. The shaft bottom wall portion 51a covers the entire length of the two short sides of the shaft bottom portion 51 that extend in the Y direction and about 1 / 3 of the short side sides on both sides of the two long sides that extend in the X direction. That is, it is provided on the portion of the outer periphery of the shaft bottom portion 51 other than about 1 / 3 of the central portion of the long side.

[0061] The shaft base portion 52 protrudes forward from the central portion of the shaft bottom portion 51. The shaft base portion 52 includes a cylindrical shaft base rear portion 52a with a substantially constant diameter from the rear to the front, a shaft base inclined portion 52b that extends forward from the shaft base rear portion 52a and gradually decreases in diameter, and a shaft base front portion 52c that is provided on the front side of the shaft base inclined portion 52b, has a larger diameter than the front end of the shaft base inclined portion 52b, and gradually decreases in diameter from there. On the outer surface of the step portion provided between the shaft base inclined portion 52b and the shaft base front portion 52c, a rearward shaft-side locking surface 52d is formed.

[0062] The shaft screw portion 53 is an elongated rod-shaped member that extends forward from the shaft base portion 52, and shaft body side stopper ribs 53a are formed at two locations on the outer periphery of the root of the rear end of this shaft screw portion 53. The front side of the shaft screw portion 53 where the shaft body side stopper ribs 53a are formed has a threaded outer periphery.

[0063] When the holding body 40 moves rearward in the shaft Z direction due to the rotation of the shaft body 50, the holding body side stopper rib 42 provided on the bottom surface of the holding body 40 abuts against the shaft body side stopper rib 53a. As a result, the relative rotation between the holding body 40 and the shaft body 50 is restricted, and the movement of the holding body 40 toward the rear end side in the shaft Z direction is prevented.

[0064] (Grip body 60) The grip body 60 is disposed on the rear side of the housing cylinder portion 11 and outside the shaft base portion 52 of the shaft body 50. The grip body 60 includes a grip outer cylinder portion 61 having a rectangular cross section, a grip inner cylinder portion 63 disposed inside the grip outer cylinder portion 61, and a grip front wall portion 62 covering the front end between the grip outer cylinder portion 61 and the grip inner cylinder portion 63. The shaft base portion 52 is disposed inside the grip inner cylinder portion 63.

[0065] The grip body 60 further has a grip annular convex portion 64 protruding from the rear end of the grip inner cylinder portion 63 toward the inner diameter side, and a grip plate-shaped rib 65 extending rearward along the inner surface of the grip outer cylinder portion 61 from the rear surface of the grip front wall portion 62. A grip rear end opening 66 is provided at the rear end of the grip outer cylinder portion 61.

[0066] The shaft base portion 52 of the shaft body 50 is disposed inside the grip inner cylinder portion 63. The shaft screw portion 53 is screwed into the through screw hole 41 of the holding body 40 inside the housing cylinder portion 11, and further extends forward and extends into the solid content 100 held by the holding body 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 is in contact with the inner surface of the grip outer cylinder portion 61. Thereby, the shaft body 50 and the grip body 60 can rotate integrally.

[0067] As shown in FIG. 4, since the front surface of the grip annular convex portion 64 of the grip body 60 is in contact with the sleeve side engagement surface 12d of the sleeve body 10, the forward movement of the grip body 60 is restricted by the sleeve body 10. Further, since the rear end surface of the grip plate-shaped rib 65 of the grip body 60 is in contact with the front end surface of the shaft bottom wall portion 51a of the shaft body 50, the rearward movement of the grip body 60 is restricted by the shaft body 50. That is, by being sandwiched between the sleeve body 10 and the shaft body 50, the position of the grip body 60 in the axial Z direction is restricted.

[0068] Since the front surface of the cylindrical side locking rib 12c of the sleeve body 10 is in contact with the shaft side locking surface 52d of the shaft body 50, the forward movement of the shaft body 10 is restricted by the shaft body 50. Further, since the sleeve side engaging surface 12d of the sleeve body 10 is in contact with the front surface of the grip annular convex portion 64 of the grip body 60, the backward movement of the sleeve body 10 is restricted by the grip body 60.

[0069] Since the shaft bottom wall portion 51a of the shaft body 50 is in contact with the grip plate-shaped rib 65 of the grip body 60, the forward movement of the shaft body 50 is restricted by the grip body 60. Further, as described above, since the shaft side locking surface 52d of the shaft body 50 is in contact with the front surface of the cylindrical side locking rib 12c of the sleeve body 10, the backward movement of the shaft body 50 is restricted by the sleeve body 10.

[0070] From the above, the positions of the grip body 60, the sleeve body 10, and the shaft body 50 in the axial Z direction are fixed, and the feeding container 1 maintains the assembled state shown in FIG. 4.

[0071] (Attachment to the cap mounting portion 14 of the cap body 20) When the cap body 20 is placed over the cap mounting portion 14 and slid backward, as the cap body 20 slides on the cylindrical portion slope 14G while the cap body slopes 20G of the cap side rising convex portions 20x and 20y of the cap body 20 move in the axial Z direction with respect to the housing cylindrical portion 13 and climb over the cylindrical portion slope 14G.

[0072] Here, the inclination angle α1 of the cap body slope 20G with respect to the axis Z and the inclination angle β1 of the cylindrical portion slope 14G with respect to the axis Z are smaller than the inclination angle α2 of the cap body steep slope 20S with respect to the axis Z and the inclination angle β2 of the cylindrical portion steep slope 14S with respect to the axis Z. Therefore, when the cap body 20 is attached to the cap mounting portion 14, the cap body 20 can be smoothly slid with respect to the cap mounting portion 14. Further, if at least one of the angle α1 and the angle β1 is less than 15 degrees, the cap body 20 can be more smoothly slid with respect to the cap mounting portion 14.

[0073] When the vertices of the cap-side mounting convex portions 20x and 20y exceed the cylindrical portion gentle slope surface 14G, the cap-side mounting convex portions 20x and 20y drop along the cylindrical portion steep slope surface 14S of the cylindrical portion-side mounting convex portions 14x and 14y. Then, the cap body steep slope surface 20S and the cylindrical portion steep slope surface 14S come into contact with each other.

[0074] At this time, since a change occurs in the force with which the user pushes the cap body 20 into the cap mounting portion 14, a click feeling (the feeling of the cap body 20 being fitted) can be obtained, and at the same time, the cap body 20 fits with the cap mounting portion 14.

[0075] (First airtight structure A) The feeding container 1 of the embodiment has a first airtight structure A composed of a seal body 30, a cap contact portion 21, and a groove portion 16. When the cap body 20 is mounted on the cap mounting portion 14, in the first airtight structure A, the cap contact portion 21 comes into contact with the planar contact surface 31 of the seal body 30 disposed in the groove portion 16 and compresses the contact surface 31 in the longitudinal direction (axis Z direction).

[0076] As described above, on the inner surface side of the seal body 30, on the rear side in the axis Z direction, the inner inner surface 161 of the groove portion 16 is fitted with the inner surface of the seal body 30. Thereby, the seal body 30 is held with respect to the groove portion 16, that is, the sleeve body 10.

[0077] Further, on the bottom surface 16b of the groove portion 16, a rib portion 16r protruding forward in the axis Z direction over the entire circumference is provided. When the seal body 30 is disposed in the groove portion 16, the rear surface of the seal body 30 comes into contact with and is pressed by the rib portion 16r. Thereby, the seal body 30 is in close contact with the groove portion 16, that is, the sleeve body 10, and the airtightness between the seal body 30 and the sleeve body 10 is maintained.

[0078] In the embodiment, the rear side (bottom surface) of the seal body 30 is flat and the rib portion 16r is provided in the groove portion 16. However, different from the embodiment, a rib portion may be provided on the seal body and the bottom surface of the groove portion may be flat.

[0079] On one side, on the outer surface side of the seal body 30, in the front side in the axial Z direction (the opening side of the groove portion 16), a gap with a distance d12 is formed between the outer inner surface 162 of the groove portion 16 and the outer surface of the seal body 30. And, in the front side in the axial Z direction, a gap with a distance d11 is formed between the inner inner surface 161 of the groove portion 16 and the inner surface of the seal body 30.

[0080] When the cap body 20 is attached to the cap attachment portion 14, the cap contact portion 21 compresses the contact surface 31 of the seal body 30 disposed in the groove portion 16 in the longitudinal direction. At this time, in the front side (opening side) of the groove portion 16, the seal body 30 is not fixed, and gaps are provided between the inner inner surface 161 and the outer inner surface 162 of the groove portion 16 and the seal body 30. Therefore, the seal body 30 can be sufficiently elastically deformed in a direction orthogonal to the axial Z direction, which is the direction in which the cap body 20 opens and closes, and the housing cylinder portion 11 is kept in an airtight state.

[0081] In a state where the seal body 30 is not compressed, 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 does not contact the sleeve body 10) is the length by which the seal body 30 is compressed in the axial Z direction by the cap body 20 (from the length in the axial Z direction of the seal body 30 before being compressed, subtract the axial Z direction interval between the rib portion 16r and the cap contact portion 21 in a state where the cap body 20 is attached to the cap attachment portion 14). It is preferably equal to or greater than the length).

[0082] Different from the embodiment, if there is no gap between the side surface of the seal body and the inner inner surface and the outer inner surface of the groove portion, and the direction orthogonal to the axial Z direction is suppressed by the inner inner surface and the outer inner surface of the groove portion, the seal body becomes difficult to deform in the direction orthogonal to the axial Z direction. In this case, when pressing the seal body in the axial Z direction by the cap contact portion, a large force is required. Also, when deforming the seal body with a large force, the repulsive force of the seal body also becomes large.

[0083] Then, in the fitting by the climbing fitting method in which the cap-side climbing convex portion climbs over the cylinder portion-side climbing convex portion so that the cap body is attached to the cap attachment portion, the cap body is likely to come off from the cap attachment portion. If the fitting force is increased so that it does not come off, the cap body cannot be easily attached and detached by hand. Although it is conceivable to attach the cap by screw fitting or the like instead of the climbing fitting method, it is difficult in design to adopt screw fitting for the fitting between the non-circular cap body and the accommodating cylinder portion. Further, when screw fitting is used, the attachment and detachment operation is not as easy as the climbing fitting method of the embodiment. Also, in screw fitting, the sealing body is likely to be worn by rubbing against the cap body, and the durability as the feeding container 1 is reduced.

[0084] However, according to the first airtight structure A of the embodiment, since a gap is provided between the inner inner surface 161 and the outer inner surface 162 of the groove portion 16 and the sealing body 30 on the front side of the groove portion 16, the sealing body 30 can be more easily elastically deformed in a direction orthogonal to the axial direction Z compared to the case where no gap is provided.

[0085] Therefore, when attaching the cap body 20, the force for pressing the sealing body 30 by the cap contact portion 21 may be small. Also, the repulsive force of the sealing body 30 against the cap body 20 when the cap body 20 is attached is weakened. For this reason, the fitting force of the cap body 20 to the cap attachment portion 14 does not need to be so strong. Therefore, it is possible to attach the cap body using the climbing fitting method in which the cap-side climbing convex portions 20x and 20y on the inner surface of the cap body climb over the gentle slopes of the cylinder portion-side climbing convex portions 14x and 14y of the cap attachment portion 14. Then, since the sealing body 30 is not rubbed by the cap body 20, it is less likely to wear and the durability as the feeding container 1 is improved.

[0086] Further, when the cap body 20 is attached to the cap attachment portion 14, it is formed at a position where the cap body steep slopes 20S of the cap-side climbing convex portions 20x and 20y and the cylinder portion steep slopes 14S of the cylinder portion-side climbing convex portions 14x and 14y come into contact.

[0087] In this way, when the steep slope 20S of the cap body abuts against the steep slope 14S of the cylindrical portion, the positioning in the axial Z direction of the cap body 20 with respect to the housing cylindrical portion 11 is good, and the seal body 30 can be accurately compressed in the longitudinal direction by the cap abutting portion 21 of the cap body 20.

[0088] For example, different from the embodiment, when the cap body is fitted to the cap mounting portion 14 by abutting an arcuate convex portion formed on the cap body and an arcuate convex portion formed on the outer surface of the housing cylindrical portion, if the size and shape of the arcuate convex portion change slightly due to manufacturing errors or temperature changes, etc., the inclination of the tangent line at the portion where the convex portions abut with respect to the axis Z changes. Then, the fitting force of the cap body 20 with respect to the cap mounting portion 14 changes, and there is a possibility that it cannot withstand the repulsive force from the seal body 30.

[0089] However, in the embodiment, the cap body 20 and the cap mounting portion 14 are fitted by the abutment of the steep slope 20S of the cap body formed on the cap body 20 and the steep slope 14S of the cylindrical portion formed on the cap mounting portion 14. Therefore, even when the sizes and shapes of the cap body 20 and the cap mounting portion 14 change slightly, the inclination angles of these steep slopes with respect to the axis Z do not change, so the fitting force hardly changes and a constant fitting force can be maintained.

[0090] Also, when making the cap body 20 and the housing cylindrical portion 11 airtight as described above, the pressing force of the seal body 30 needs to be a predetermined amount or more. However, if the force pressing the seal body 30 is too strong, the repulsive force also becomes large, and there is a possibility that the cap body 20 comes off.

[0091] In the embodiment, the inclination angle α2 of the steep slope 20S of the cap body with respect to the axis Z and the inclination angle β2 of the steep slope 14S of the cylindrical portion with respect to the axis Z are 15° or more and 30° or less, and since the angle α2 and the angle β2 are substantially equal, the space between the cap body 20 and the housing cylindrical portion 11 can be made sufficiently airtight, and also the repulsive force is appropriate, so there is no possibility that the cap body 20 comes off.

[0092] Further, by bringing the steep slope 20S of the cap body into contact with the steep slope 14S of the cylindrical portion, the positional relationship between the cap body 20 and the housing cylindrical portion 11 can be kept constant, and it is possible to reliably prevent the cap body 20 from coming off due to the repulsion of the seal body 30. Therefore, the amount of compression of the seal body 30 can be set to the minimum necessary. As a result, since the length of the seal body 30 can also be made the minimum necessary, it leads to downsizing of the container.

[0093] In the case of an airtight structure in which a generally used cap body is elastically deformed and attached to the cap mounting portion of the housing cylindrical portion in a feeding container, if the cap body and the housing cylindrical portion are not circular, it is difficult to uniformly deform and closely attach the cap body over the entire circumferential direction, so it is difficult to maintain airtightness.

[0094] However, the first airtight structure A of the embodiment is not an airtight structure in which the cap body is elastically deformed and attached to the cap mounting portion, but a structure in which the seal body 30, the cap contact portion 21, and the seal body 30 are arranged in the groove portion 16, and the seal body 30 is pressed by the cap contact portion 21 provided on the cap body 20.

[0095] Therefore, even if the cap body 20 and the housing cylindrical portion 11 are not circular, sufficient airtightness can be ensured between the cap body 20 and the housing cylindrical portion 11. Therefore, as in the embodiment, the cross section of the solid content 100 can be rectangular, and the shape of the housing cylindrical portion 11 can also be rectangular.

[0096] Conventionally, if the contact portion between the cap body and the housing cylindrical portion is not circular, it has been difficult to uniformly deform the cap body over the entire circumferential direction, and it has been difficult to maintain airtightness. For this reason, even when the cross section of the solid content is square, the contact portion between the cap body and the housing portion may be circular.

[0097] However, when the cross-sectional shape of the solid content is non-circular, in the accommodating cylinder part, if the contact part with the cap body is circular and the solid paste with a non-circular cross-section can be accommodated inside, the cross-sectional shape of the accommodating cylinder part will become larger than the cross-sectional shape of the solid content. In particular, when the cross-sectional shape of the solid content is a rectangle or the like other than a regular polygon, the difference becomes significant.

[0098] On the other hand, for the feeding container 1 of the embodiment, in accordance with the shape of the solid content 100 with a rectangular cross-section, the shape of the accommodating cylinder part 11 can also be made rectangular. Therefore, there is no need to make the accommodating cylinder part 11 larger than necessary for the solid content 100, and the feeding container 1 will not become larger than necessary.

[0099] (Effect of notch 13b and cap covering part 22) The cap covering part 22 surrounds the outside of the cap contact part 21 and protrudes longer in the axial Z direction than the cap contact part 21. When the cap body 20 is attached to the cap attachment part 14, the cap covering part 22 enters the notch 13b provided over the entire circumference at the outermost front end of the part where the groove part 16 is formed in the cylinder part main body 13.

[0100] Then, since the opening of the groove part 16 where the seal body 30 is arranged is covered by the cap covering part 22, the seal body 30 cannot be contacted from the outside, is protected from the outside, and deterioration of the seal body 30 can be prevented. Furthermore, since the seal body 30 is covered by the cap covering part 22 and cannot be seen from the outside, it is also excellent in aesthetics.

[0101] Also, since the cap covering part 22 exists, even if the cap body 20 removed from the cap attachment part 14 is placed on, for example, a table with the rear side (opening side) facing downward, the cap contact part 21 does not touch the table. Therefore, it is difficult for dust or the like to adhere to the cap contact part 21, and the risk that the adhesion of the adhered dust or the like hinders the airtightness with the seal body 30 can be reduced.

[0102] (Second airtight structure B) According to the embodiment, the rear cylinder portion 12 of the sleeve body 10 is sandwiched between the grip inner cylinder portion 63 of the grip body 60 and the shaft base portion 52 of the shaft body 50. And the sleeve-side airtight formation surface 12e, which is the inner surface of the small-diameter portion 12b of the rear cylinder portion 12 of the sleeve body 10, and the shaft-side airtight formation surface 52e, which is the outer surface of the rear portion 52a of the shaft base portion of the shaft base portion 52, are in close contact. The second airtight structure B in which the sleeve-side airtight formation surface 12e and the shaft-side airtight formation surface 52e are in close contact ensures airtightness of the inside of the sleeve body 10 with respect to the outside.

[0103] The large-diameter portion 12a of the sleeve body 10 extends to the rear side in the axial Z direction from the rear end of the housing cylinder portion 11 (the rear end of the cylinder portion main body 13), and the sleeve-side airtight formation surface 12e is located on the cylinder-side locking rib 12c and the small-diameter portion 12b. That is, the fitting structure and the airtight structure between the sleeve body 10 and the shaft body are formed on the rear side in the axial Z direction from the rear end of the sleeve body 10.

[0104] Conventionally, the fitting structure and / or the airtight structure between the sleeve body and the shaft body were provided inside the cylinder portion main body 13 on the front side from the rear end of the cylinder portion main body 13 of the sleeve body 10 and on the front side of the grip body. In this case, the feeding container as a whole becomes longer in the axial Z direction.

[0105] However, in the embodiment, the second airtight structure B between the sleeve body 10 and the shaft body 50 due to the close contact between the sleeve-side airtight formation surface 12e and the shaft-side airtight formation surface 52e is provided inside the portion where the grip body 60 is arranged in the axial Z direction. Therefore, the length of the feeding container 1 can be shortened, and the feeding container 1 can be made compact without reducing the amount of the solid content 100 compared with the conventional structure.

[0106] By inserting the shaft body 50 from the rear cylinder portion 12 of the sleeve body 10, an airtight structure is formed by the close contact between the sleeve-side airtight formation surface 12e and the shaft-side airtight formation surface 52e, so that an airtight structure can be realized with easy assemblability.

[0107] (Feeding operation) From the state of FIG. 4, the cap body 20 is removed from the accommodating cylinder portion 11 of the sleeve body 10, and while holding the accommodating cylinder portion 11, the grip body 60 is rotated. Then, the shaft body 50 rotates integrally with the grip body 60. The outer shape of the holding body 40 engages with the inner shape of the accommodating cylinder portion 11 of the sleeve body 10, and the holding body 40 does not rotate relative to the sleeve body 10. When the shaft body 50 rotates, the holding body 40 screwed with the shaft screw portion 53 of the shaft body 50 moves in the axial Z direction. As the holding body 40 moves forward in the axial Z direction, the solid content 100 held by the holding body 40 is fed forward in the axial Z direction.

[0108] After feeding out the solid content 100, when the grip body 60 is rotated in the direction opposite to that during feeding out, the holding body 40 moves rearward in the axial Z direction, and accordingly, the solid content 100 is fed back into the accommodating cylinder portion 11.

[0109] (Removal of the cap body 20 from the cap mounting portion 14) When 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 cylinder portion 11 of the sleeve body 10 (without relative rotation).

[0110] When removing the cap body 20 from the sleeve body 10 while holding the grip body, a force is applied to move the sleeve body 10 forward together 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. Since the shaft-side locking surface 52d and the large-diameter portion 12a abut against each other on surfaces that are substantially orthogonal to each other in the axial Z direction, they have a structure that does not easily come off. Therefore, even if the sleeve body 10 is pulled, it does not detach from the shaft body 50. Also, since the sleeve body and the shaft body 50 that sandwich 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 do not separate.

[0111] (Other effects of the feeding container 1) The outer peripheral shape of the front end of the grip body 60 is substantially equal to the outer peripheral shape of the rear end of the accommodation cylinder portion 11 of the sleeve body 10. Therefore, since there is no step between the rear end of the accommodation cylinder portion 11 of the sleeve body 10 and the front end of the grip body 60, the grip body 60 and the sleeve body 10 have integrality, and the appearance of the feeding container 1 is improved.

[0112] Since a grip front wall portion 62 orthogonal to the axial direction Z is provided on the front side of the grip body 60, foreign matter is less likely to enter the grip body 60 even when the grip body 60 is rotated.

[0113] Further, since the grip body 60 has no portion engaged by deformation such as press-fitting with other members, the durability performance is excellent.

[0114] The seal body 30 is preferably a separate part from the accommodation cylinder portion 11 and the cap body 20. Different from the embodiment, insert molding or two-color molding may be used to manufacture the seal body as an integral part with, for example, the accommodation cylinder portion or the cap body. However, in this case, the shape of the accommodation cylinder portion or the cap body is limited, the manufacturing process becomes complicated, and the manufacturing is not easy. In addition, when the seal body and the accommodation cylinder 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 according to the thickness of the mold, and the gap becomes larger than necessary and the shape also becomes larger.

[0115] However, in the embodiment, since the seal body 30 is a separate part from the accommodation cylinder portion 11 and the cap body 20, the manufacturing is easy. In addition, since the gap between the groove portion 16 and the seal body 30 can be appropriately reduced, the feeding container 1 as a whole can have a compact shape.

[0116] Substantially the entire surface of the seal body 30 other than the contact surface 31 that contacts the cap body 20 is disposed within the groove portion 16. Therefore, the possibility that the user touches the seal body 30 is reduced, and deterioration of the seal body 30 can be prevented.

[0117] The shape of the seal body 30 is preferably line-symmetric with respect to an axis orthogonal to the axis Z. This eliminates the front-back directionality when assembling the seal body 30 into the groove 16, improving the assemblability.

[0118] As described above, the first embodiment of the present invention has been explained, but the present invention is not limited to this, and various modifications are possible. For example, in the embodiment, the first airtight structure A was provided between the cap body 20 and the sleeve body 10 (cap mounting portion 14) with a substantially rectangular cross-section. However, it is not limited to this, and it may be provided between the cap body and the sleeve body (cap mounting portion) with a non-circular cross-section other than rectangular.

[0119] Also, in the embodiment, the groove 16 is provided on the front side of the housing cylinder portion 11, and the cap contact portion 21 is provided on the cap body 20. However, it is not limited to this, and an annular groove may be provided so as to open axially on the rear side of the cap body, and the contact portion may be provided on the front side of the housing cylinder portion.

[0120] In the embodiment, the cap covering portion 22 is provided on the cap body 20. However, it is not limited to this, and it may be provided on the housing cylinder portion 11.

[0121] In the embodiment, the rear cylinder portion 12 extends to the rear side of the rear end of the housing cylinder portion 11, and in the direction orthogonal to the axis Z direction, the rear cylinder portion 12 is covered by the grip body 60. Different from the embodiment, by further extending the housing cylinder portion 11 to the rear side, in the direction orthogonal to the axis Z direction, the rear cylinder portion 12 may be covered by the housing cylinder portion 11, and the grip body 60 may be located on the rear side of the rear cylinder portion 12 and the housing cylinder portion 11.

[0122] In the embodiment, the seal body 30 is separate from the housing cylinder portion 11, and the form in which the seal body 30 is arranged in the groove 16 formed in the housing cylinder portion 11 has been described. However, it is not limited to this, and the seal body and the housing cylinder portion 11 may be manufactured by two-color molding.

[0123] (Second Embodiment) Figs. 7 and 8 are diagrams for explaining the shape of the seal body 30A according to the second embodiment. Fig. 7 is an enlarged view of the seal body 30A portion in a cross section perpendicular to the same axis Z as in Fig. 6, showing a state where the cap body 20 is not attached. Fig. 8 is an enlarged view of the seal body 30A portion in a cross section perpendicular to the same axis Z as in Fig. 6, showing a state where the cap body 20 is attached.

[0124] The difference between the second embodiment and the first embodiment lies in the contact surface 31A of the seal body 30A, the rear surface 32A on the side opposite to the contact surface 31A, and the shape of the bottom surface 16Ab of the groove portion 16. Since the other configurations are the same as those in the first embodiment, the description of the same parts will be omitted.

[0125] (Contact surface 31A) In the first embodiment, in the cross section shown in Fig. 6, the contact surface 31 of the seal body 30 disposed in the groove portion 16 was planar and perpendicular to the axis Z. However, in the second embodiment, the contact surface 31A of the seal body 30A is inclined such that the side closer to the inner surface of the seal body 30 protrudes forward more than the side closer to the outer surface with respect to the plane perpendicular to the axis Z.

[0126] (Rear surface 32A) Also, in the first embodiment, the rear surface on the side opposite to the contact surface 31 of the seal body 30 was planar and perpendicular to the axis Z. However, in the second embodiment, the rear surface 32A on the side opposite to the contact surface 31A of the seal body 30A is inclined such that the side closer to the inner surface of the seal body 30 protrudes rearward more than the side closer to the outer surface with respect to the plane perpendicular to the axis Z.

[0127] That is, in the cross section shown in Fig. 7, the cross section of the seal body 30 has a trapezoidal shape with a shorter length on the outer surface side and a longer length on the inner surface side.

[0128] The inclination angle γ of the contact surface 31A with respect to the plane perpendicular to the axis Z is 10° or more and 40° or less.

[0129] (Bottom surface 16b of the groove portion 16) Furthermore, in the first embodiment, the bottom surface 16b of the groove portion 16 was planar and orthogonal to the axis Z except for the portion where the rib portion 16r was provided. However, in the second embodiment, the bottom surface 16Ab of the groove portion 16 is inclined with respect to the plane orthogonal to the axis Z in accordance with the inclination of the rear surface 32A of the seal body 30A on the side closer to the inner surface of the seal body 30 than the portion where the rib portion 16r is provided.

[0130] As shown in FIG. 8, when the cap body 20 is attached to the housing cylinder portion 11, the cap contact portion 21 compresses the contact surface 31A of the seal body 30A disposed in the groove portion 16 in the longitudinal direction. At this time, also in the second embodiment as in the first embodiment, the seal body 30A can be sufficiently elastically deformed, and the housing cylinder portion 11 is kept in an airtight state.

[0131] Furthermore, according to the second embodiment, in addition to the effects of the first embodiment, it also has the following effects. For example, when the solid content 100 protrudes from the cylinder opening 14a, when the cap body 20 is opened and closed, the protruding solid content 100 may adhere to the end surface of the cap body 20. When the solid content 100 adheres to the end surface of the cap body 20, when the cap body 20 is attached, the solid content 100 attached to the end surface of the cap body 20 may adhere to the contact surface 31A of the seal body 30 as a foreign matter.

[0132] When foreign matter adheres to the contact surface 31A of the seal body 30, the confidentiality performance between the cap contact portion 21 and the contact surface 31A may be inhibited by the foreign matter. Also, when the foreign matter is an adhesive like glue, if it dries in a state of being sandwiched between the cap contact portion 21 and the contact surface 31A, the cap contact portion 21 and the contact surface 31A may be adhered, and when the cap body 20 is opened, the seal body 30 may be pulled by the cap body 20 and come off from the groove portion 16.

[0133] However, in the second embodiment, even if foreign matter adheres to the contact surface 31A of the seal body 30, when the cap body 20 is attached, the cap contact portion 21 that compresses the contact surface 31A pushes the foreign matter outward along the inclined contact surface 31A, so that the possibility of foreign matter being pinched into the airtight portion can be reduced.

[0134] Also, even if the cap contact portion 21 and the contact surface 31A are adhered with a small amount of foreign matter pinched in, the force in the axial Z direction when the cap body 20 is opened is dispersed by the inclined surface, so the seal body 30 is difficult to come off.

[0135] (Third Embodiment) FIG. 9 and FIG. 10 are diagrams for explaining the shape of the seal body 30B according to the third embodiment. FIG. 9 is an enlarged view of the seal body 30B portion in a cross section perpendicular to the axis Z similar to FIG. 6, showing a state where the cap body 20B is not attached. FIG. 10 is an enlarged view of the seal body 30B portion in a cross section perpendicular to the axis Z similar to FIG. 6, showing a state where the cap body 20B is attached.

[0136] The difference between the third embodiment and the first embodiment lies in the contact surface 31B of the seal body 30B and the shape of the rear end of the cap body 20. Since the other configurations are the same as those in the first embodiment, the description of the same parts is omitted.

[0137] (Contact Surface 31B) In the first embodiment, in the cross section shown in FIG. 6, the contact surface 31 of the seal body 30 disposed in the groove portion 16 was planar and perpendicular to the axis Z. However, in the third embodiment, the contact surface 31B of the seal body 30B is semi-circular and protrudes forward with respect to the plane perpendicular to the axis Z.

[0138] (Shape of the Rear End of the Cap Body 20) In the first embodiment, in the cross section shown in FIG. 6, at the rear (opening side) end of the cap body 20, there was a cap contact portion 21 which was a protrusion protruding rearward in the Z-axis direction over the entire circumference of the outer periphery of the cap body 20. However, in the third embodiment, as shown in FIG. 10, the cap contact portion 21B at the rear end of the cap body 20 is in a planar shape orthogonal to the Z-axis.

[0139] When the cap body 20 is attached to the housing cylinder portion 11, the rear end of the planar cap body 20 compresses, in the longitudinal direction, the semi-circular contact surface 31B protruding forward in the sealing body 30B disposed in the groove portion 16. At this time, as shown in FIG. 10, the cap contact portion 21B of the planar cap body 20 presses the contact surface 31B of the sealing body 30B which is semi-circular and protrudes forward.

[0140] In the third embodiment, although the cap contact portion 21B of the cap body 20 is planar, since the contact surface 31B of the sealing body 30B is semi-circular and protrudes forward, in the third embodiment as well as in the first embodiment, the sealing body 30B can be sufficiently elastically deformed and the housing cylinder portion 11 is kept in an airtight state.

[0141] (Fourth Embodiment) FIGS. 11 and 12 are diagrams for explaining the shape of the sealing body 30C according to the fourth embodiment. FIG. 11 is an enlarged view of the sealing body 30C portion in a cross section orthogonal to the Z-axis similar to FIG. 6, showing a state where the cap body 20C is not attached. FIG. 12 shows a state where the cap body 20C is attached.

[0142] The difference between the fourth embodiment and the third embodiment is the shape of the contact surface 31C of the sealing body 30C. Since the other configurations are the same as those in the third embodiment, the description of the same parts is omitted.

[0143] (Contact Surface 31C) In the third embodiment, the contact surface 31B of the seal body 30B is semi-circular and protrudes forward with respect to the plane orthogonal to the axis Z, and the central portion in the thickness direction of the seal body 30B protrudes the most. However, in the fourth embodiment, the contact surface 31C of the seal body 30C is arc-shaped and protrudes forward with respect to the plane orthogonal to the axis Z, but the portion closer to the outer surface in the thickness direction of the seal body 30C protrudes the most.

[0144] Also in the fourth embodiment, when the cap body 20 is attached to the housing cylinder portion 11, the cap contact portion 21C of the flat cap body 20 compresses, in the longitudinal direction, the contact surface 31C that protrudes in an arc shape forward, of the seal body 30C disposed in the groove portion 16. At this time, as shown in FIG. 10, the cap contact portion 21C of the flat cap body 20 presses the contact surface 31C of the arc-shaped seal body 30C that protrudes forward. In the fourth embodiment, the cap contact portion 21C of the cap body 20 is flat, but since the contact surface 31C of the seal body 30C is arc-shaped and protrudes forward, also in the fourth embodiment as in the third embodiment, the seal body 30C can be sufficiently elastically deformed, and the housing cylinder portion 11 is kept in an airtight state.
