Description

[Technical Field]

[0001] The present disclosure relates to a dispensing container cartridge and a dispensing container. [Background technology]

[0002] Patent Document 1 describes an applicator container that includes a cartridge that holds an applicator body and a main body to which the cartridge is detachable. The cartridge is detached from the main body after the applicator body has been used up, for example. A new cartridge can be attached to the main body without the cartridge attached.

[0003] The cartridge has a cylindrical sleeve, a cylindrical portion inserted into the sleeve, and a screw portion that moves axially inside the cylindrical portion. The cylindrical portion has an exposed portion that is exposed to the outside of the cartridge when inserted into the sleeve. The exposed portion is provided with a main body engaging portion that engages with the main body. When the cylindrical portion rotates relative to the sleeve and the screw portion, the screw portion moves axially relative to the cylindrical portion. This allows the applicator body to be advanced and retracted. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2023-141882 Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-described cartridge, the main body engaging portion is exposed. Therefore, when the cartridge is not attached to the main body, the main body engaging portion may unintentionally come into contact with a user's finger or an object. If an object or the like comes into contact with the main body engaging portion, the cylindrical portion may unintentionally rotate, causing the applicator body to be extended.

[0006] An object of the present disclosure is to provide a dispensing container cartridge and a dispensing container that can prevent the applicator body from being unintentionally dispensed by the user. [Means for solving the problem]

[0007] The dispensing container cartridge according to the present disclosure is (1) a dispensing container cartridge having an opening through which the applicator body is dispensed and removably attached to a container body. It comprises a tubular member, a moving body having a male thread formed on its outer circumferential surface and moving the applicator body toward the opening, and a screw tube having a female thread formed on its inner circumferential surface that screws into the male thread. The tubular member houses the moving body and the screw tube and is removably attached to the container body. An engaging portion that engages with an engaged portion of the container body is provided inside the tubular member. When the dispensing container cartridge is attached to the container body, the engaging portion engages with the engaged portion so that either the moving body or the screw tube and the container body can rotate synchronously.

[0008] In this dispensing container cartridge, a male screw formed on the outer surface of the moving body threads into a female screw formed on the inner surface of the screw tube. This allows the moving body to advance relative to the screw tube and move the applicator. In this dispensing container cartridge, the tubular member has an engaging portion inside the tubular member that engages with an engaged portion of the container body. By providing the engaging portion inside the tubular member, it is possible to prevent the user's fingers or other objects from unintentionally coming into contact with the engaging portion. Furthermore, when the dispensing container cartridge is attached to the container body and the engaging portion engages with the engaged portion, either the moving body or the screw tube can rotate synchronously with the container body. In other words, it is only when the engaging portion provided inside the tubular member engages with the engaged portion that either the moving body or the screw tube can rotate synchronously with the container body. Therefore, it is possible to prevent rotation of either the moving body or the screw tube when the dispensing container cartridge is not attached to the container body. This therefore prevents the user from unintentionally dispensing the applicator.

[0009] (2) In the above (1), the engaging portion may be provided on the screw barrel. Since the male screw formed on the outer surface of the movable body is screwed into the female screw formed on the inner surface of the screw barrel, the outer diameter of the screw barrel is larger than the outer diameter of the movable body. Therefore, compared to when the engaging portion is provided on the movable body, the strength of the engaging portion can be increased, making the engaging portion less likely to be damaged.

[0010] (3) In the above (2), the engaging portion may be provided on the end face of the screw barrel opposite the opening. When the dispensing container cartridge is attached to the container body, the end face of the screw barrel is brought into contact with the engaged portion, thereby allowing the engaging portion to engage with the engaged portion. This makes it easy to engage the engaging portion with the engaged portion.

[0011] (4) In any of the above (1) to (3), the screw barrel may have a wall portion that closes the internal space of the screw barrel. In this case, the wall portion closes the internal space of the screw barrel, thereby improving the airtightness of the internal space of the screw barrel. Furthermore, by providing a wall portion that closes the internal space of the screw barrel, the strength of the screw barrel can be sufficiently improved.

[0012] A dispensing container according to the present disclosure (5) includes the dispensing container cartridge according to any one of (1) to (4) above, and a container body. The container body has an outer tube member and a connecting member that rotates synchronously with the outer tube member inside the outer tube member. The connecting member has an engaged portion and an elastic portion that biases the engaged portion toward the engaging portion. The engaged portion is provided at the end of the connecting member on the engaging portion side.

[0013] The connecting member has an elastic portion that biases the engaged portion toward the engaging portion. Therefore, when the engaging portion is engaged with the engaged portion, the engaging portion approaches the engaged portion and is biased toward the engaging portion, making it easy to bring the engaging portion into close contact with the engaged portion. Because the connecting member rotates synchronously with the outer tube member, when torque is applied to the outer tube member, torque can be applied to the engaging portion via the engaged portion of the connecting member. This allows the applicator to be dispensed. [Effects of the Invention]

[0014] According to the present disclosure, it is possible to prevent the applicator body from being unintentionally extended by the user. [Brief explanation of the drawings]

[0016] Hereinafter, embodiments of a dispensing container cartridge and a dispensing container according to the present disclosure will be described with reference to the drawings. In the description of the drawings, identical or corresponding elements are designated by the same reference numerals, and duplicate explanations will be omitted as appropriate. The drawings may be partially simplified or exaggerated to facilitate understanding, and the dimensional proportions and the like are not limited to those shown in the drawings.

[0017] In the present disclosure, the term "applicator body" refers to an object that is applied to a target area. The "applicator body" may be, for example, a cosmetic or drawing material such as a crayon, a cosmetic applicator such as a puff, sponge, tip, impregnated body, or brush, or a stationery item such as a writing brush. In this embodiment, an example in which the applicator body is a cosmetic will be described.

[0018] Examples of "cosmetics" include eyeliner, eyebrow pencil, eyeshadow, lipstick, lip liner, lip gloss, concealer, dial pen, and beauty stick. "Cosmetics" may also be a stick-shaped product containing a flexible material (e.g., semi-solid, soft, jelly, mousse, or a paste containing any of these).

[0019] In each embodiment described below, the dispensing container comprises a dispensing container cartridge. The term "cartridge" refers to a replaceable part. FIG. 1 is a perspective view of a dispensing container cartridge 10 according to a first embodiment. FIG. 2 is a cross-sectional view taken along line II-II in FIG. 1. Some of the parts constituting the dispensing container cartridge 10 are cylindrical. Hereinafter, the direction in which the axis of a cylindrical part of the dispensing container cartridge 10 extends will be referred to as the "axial direction D1." In a plane perpendicular to the axis of a cylindrical part, the direction toward or away from the axis will sometimes be referred to as the "radial direction." The "radially outer" refers to the radial direction away from the axis, and the "radially inner" refers to the radial direction toward the axis. The "circumferential direction" refers to the direction along a ring centered on the axis (the direction of rotation).

[0020] Dispensing container cartridge 10 comprises a tubular member 11, a screw tube 12, a moving body 13, a piston 14, and applicator M. Tubular member 11 houses screw tube 12, moving body 13, piston 14, and applicator M. Tubular member 11 comprises a front tube 15 and a rear tube 16 connected to front tube 15. Front tube 15 is formed with an opening 15a through which applicator M is dispensed. In the following description, the direction in which applicator M moves when it is dispensed from opening 15a may be referred to as the "front," "front side," or "forward," and the direction opposite to the direction in which applicator M moves may be referred to as the "rear," "rear side," or "rear."

[0021] The front tube 15 has a tapered portion 151 located on the front side of the front tube 15, and an extending portion 152 extending rearward from the rear end of the tapered portion 151. The tapered portion 151 is exposed, and the extending portion 152 is housed in the rear tube 16. The outer diameter of the tapered portion 151 becomes smaller as it approaches the opening 15a. The outer diameter of the tapered portion 151 at the rear end is larger than the outer diameter of the extending portion 152 at the front end.

[0022] The extension portion 152 has a first portion 152a located on the front side of the extension portion 152, a third portion 152c located on the rear side of the extension portion 152, and a second portion 152b located between the first portion 152a and the third portion 152c. The first portion 152a has, for example, a cylindrical shape. The first portion 152a has a front portion with a constant outer diameter and a rear portion whose outer diameter decreases with increasing distance from the rear end of the front portion. For example, the outer diameter at the front end of the rear portion is equal to the outer diameter of the front portion. The second portion 152b has a cylindrical shape. For example, the outer diameter at the rear end of the rear portion of the first portion 152a is equal to the outer diameter of the second portion 152b.

[0023] For example, the outer diameter of the third portion 152c is smaller than the outer diameter of the second portion 152b. The extension portion 152 has an annular protrusion 152d located between the second portion 152b and the third portion 152c. The annular protrusion 152d protrudes radially outward relative to the second portion 152b and the third portion 152c. The length of the first portion 152a in the axial direction D1 is shorter than the length of the second portion 152b in the axial direction D1. The length of the second portion 152b in the axial direction D1 is shorter than the length of the third portion 152c in the axial direction D1.

[0024] The front tube 15 has a front through-hole 15b extending along the axial direction D1 and a rear through-hole 15c located rearward of the front through-hole 15b inside the front tube 15. The rear through-hole 15c is in communication with the front through-hole 15b. An opening 15a is formed at the front end of the front through-hole 15b. The rear end of the front through-hole 15b is located rearward of the front end of the third portion 152c. The rear end of the rear through-hole 15c is located at the same position as the rear end of the third portion 152c.

[0025] The rear tube 16 will be described with reference to FIGS. 2 and 3. FIG. 3 is a perspective view of the rear tube 16. The rear tube 16 has a cylindrical shape. The rear tube 16 has an exposed portion 161 that is exposed when the dispensing container cartridge 10 is attached to the container body 2 (see FIG. 7), which will be described later, an attachment portion 162 that fits inside the container body 2, and a flange portion 163 that is located between the exposed portion 161 and the attachment portion 162. The exposed portion 161 is located on the front side of the rear tube 16, and the attachment portion 162 is located on the rear side of the rear tube 16. The exposed portion 161 has a front portion 161a and a rear portion 161b that extends rearward from the rear end of the front portion 161a. The front portion 161a extends along the axial direction D1. The outer diameter of the front portion 161a is smaller than the outer diameter of the rear portion 161b.

[0026] The front portion 161a has protrusions 161c on its outer circumferential surface. For example, the front portion 161a has a plurality of (for example, three) protrusions 161c. The plurality of protrusions 161c are, for example, arranged at equal intervals along the circumferential direction of the front portion 161a. The protrusions 161c protrude from the outer circumferential surface of the front portion 161a. The protrusions 161c are provided on the rear side of the front portion 161a. For example, the protrusions 161c have a circular shape when viewed from the radial outside of the front portion 161a. For example, the protrusion amount of the protrusions 161c relative to the outer circumferential surface of the front portion 161a increases as the protrusions approach the center of the protrusions 161c.

[0027] The rear portion 161b has ribs 161d on its outer circumferential surface. The ribs 161d extend forward from the rear end of the rear portion 161b. For example, the rear portion 161b has a plurality of ribs 161d (four, for example). The plurality of ribs 161d are arranged, for example, at equal intervals along the circumferential direction of the rear portion 161b. The ribs 161d extend along the axial direction D1. The ribs 161d protrude from the outer circumferential surface of the rear portion 161b.

[0028] The flange 163 has an annular (e.g., circular) shape when viewed along the axial direction D1. The outer diameter of the flange 163 is larger than the outer diameter of the rear portion 161b and the outer diameter of the mounting portion 162. The amount by which the flange 163 protrudes from the outer peripheral surface of the rear portion 161b is larger than the amount by which the rib 161d protrudes from the outer peripheral surface of the rear portion 161b.

[0029] The mounting portion 162 is a portion that is connected to the container body 2. The mounting portion 162 has a fitting portion 162a located on the front side of the mounting portion 162, an extending portion 162b located on the rear side of the mounting portion 162, and a male screw portion 162c located between the fitting portion 162a and the extending portion 162b. An annular protrusion 152d of the front tube 15 is disposed inside the fitting portion 162a. The annular protrusion 162d is provided inside the front end portion of the fitting portion 162a. The inner diameter of the annular protrusion 162d is, for example, approximately equal to the outer diameter of the second portion 152b of the extending portion 152. With the annular protrusion 152d in contact with the annular protrusion 162d, the rear tube 16 is engaged with the front tube 15 in the axial direction D1.

[0030] The male screw portion 162c has, for example, a cylindrical portion and a male screw protruding from the outer circumferential surface of the cylindrical portion. The outer diameter of the cylindrical portion is smaller than the outer diameter of the fitting portion 162a and larger than the outer diameter of the extension portion 162b. For example, the inner diameter of the male screw portion 162c is approximately equal to the outer diameter of the third portion 152c.

[0031] For example, the insides of the extension portion 162b and the male screw portion 162c have a stepped structure. The extension portion 162b and the male screw portion 162c have, on their inner surfaces, a large-diameter portion 162e located on the front side and a small-diameter portion 162f located on the rear side. The inner diameter of the large-diameter portion 162e is larger than the inner diameter of the small-diameter portion 162f. For example, the length of the large-diameter portion 162e in the axial direction D1 is longer than the length of the third portion 152c in the axial direction D1.

[0032] The screw barrel 12 will be described with reference to Figures 2 and 4. Figure 4 is a perspective view of the screw barrel 12. The screw barrel 12 is, for example, cylindrical. The screw barrel 12 has a through-hole 12a therein that extends along the axial direction D1. The screw barrel 12 has a screw portion 121 located on the front side of the screw barrel 12, an engaging portion 122 located on the rear side of the screw barrel 12, a step portion 123 extending rearward from the rear end of the screw portion 121, and a tube portion 124 located between the step portion 123 and the engaging portion 122.

[0033] The screw portion 121 has a cylindrical shape. The screw portion 121 has a female screw 121a formed on its inner circumferential surface. The female screw 121a extends around the axis of the screw tube 12 (circumferential direction). The screw portion 121 has a slit 121b penetrating the screw portion 121 in the radial direction. The screw portion 121 has, for example, a pair of slits 121b aligned along the radial direction of the screw portion 121. The pair of slits 121b are arranged at positions sandwiching the axis of the screw portion 121. The slits 121b extend in the axial direction D1. The screw portion 121 is arranged in a rear through-hole 15c of the front tube 15. The screw portion 121 does not engage with the front tube 15 in the circumferential direction and therefore does not rotate synchronously with the front tube 15.

[0034] Threaded portion 121 has an annular recess 121c on its outer surface that extends around the axis of threaded portion 121. Annular recess 121c is disposed between slit 121b and step portion 123. Dispensing container cartridge 10 has an O-ring R that is disposed in annular recess 121c. O-ring R is disposed between third portion 152c of front tube 15 and annular recess 121c. O-ring R is made of an elastic member.

[0035] The step portion 123 is a portion that faces the third portion 152c of the front tube 15 along the axial direction D1. The step portion 123 abuts, for example, against the rear end surface of the third portion 152c. The step portion 123 has a main body portion 123a that is tubular (for example, cylindrical) and a protrusion 123b that protrudes from the outer peripheral surface of the main body portion 123a.

[0036] The outer diameter of the main body portion 123a is approximately equal to the inner diameter of the small diameter portion 162f of the rear tube 16. The protrusion 123b extends along the axial direction D1. The length of the protrusion 123b in the axial direction D1 is shorter than the length of the main body portion 123a in the axial direction D1. For example, the position of the front end of the protrusion 123b is equal to the position of the front end of the main body portion 123a. For example, the amount of protrusion 123b protruding from the main body portion 123a is smaller than the difference between the inner diameter of the large diameter portion 162e and the inner diameter of the small diameter portion 162f. The protrusion 123b cannot pass through the small diameter portion 162f, preventing the screw tube 12 from slipping out from the rear of the rear tube 16. The step portion 123 is not circumferentially engaged with the rear tube 16 and therefore does not rotate synchronously with the rear tube 16.

[0037] The outer diameter of the pipe portion 124 is smaller than the outer diameter of the main body portion 123a. The outer diameter of the pipe portion 124 is smaller than the outer diameter of the engagement portion 122. The pipe portion 124 is not in contact with the inner circumferential surface of the rear cylinder 16. The pipe portion 124 is not engaged with the rear cylinder 16, and therefore does not rotate synchronously with the rear cylinder 16.

[0038] Engagement portion 122 will be described in detail with reference to Figure 5. Figure 5 is a rear perspective view of dispensing container cartridge 10. Engagement portion 122 is provided at the rear end of screw barrel 12. In other words, engagement portion 122 is provided at the end opposite opening 15a (see Figure 2) of front barrel 15. Engagement portion 122 is provided inside tubular member 11. Engagement portion 122 is located forward of the end (rear end) of tubular member 11 opposite opening 15a. Engagement portion 122 does not protrude rearward from that end of tubular member 11. Engagement portion 122 does not engage with rear barrel 16 and therefore does not rotate synchronously with rear barrel 16.

[0039] The engaging portion 122 has an engaging protrusion 122a that receives a force that rotates the screw barrel 12. For example, the engaging portion 122 has a plurality of (for example, two) engaging protrusions 122a. The plurality of engaging protrusions 122a extend so as to surround the through-hole 12a. The engaging protrusion 122a has a first surface 122b, a second surface 122c, a third surface 122d, and a pressed surface 122e. The first surface 122b, the second surface 122c, and the third surface 122d are aligned in this order along the circumferential direction of the screw barrel 12. More specifically, when viewed from the back surface of the screw barrel 12, the first surface 122b, the second surface 122c, and the third surface 122d are aligned in this order in a clockwise direction.

[0040] For example, the first surface 122b, the second surface 122c, and the third surface 122d each form a part of a circle when viewed from the back surface of the screw barrel 12. The area of the second surface 122c is larger than the area of the first surface 122b and the area of the third surface 122d. The first surface 122b is, for example, perpendicular to the axial direction D1. The third surface 122d is, for example, perpendicular to the axial direction D1.

[0041] The second surface 122c extends from the first surface 122b along the circumferential direction of the engaging portion 122 and also extends obliquely forward. The third surface 122d is located at the end of the second surface 122c opposite to the first surface 122b. The pressed surface 122e protrudes in the axial direction D1 (rearward) from the end of the third surface 122d opposite to the second surface 122c. The pressed surface 122e extends, for example, in the radial direction and the axial direction D1 of the screw barrel 12. The pressed surface 122e is, for example, perpendicular to each of the first surface 122b and the third surface 122d. The pressed surface 122e is located between the third surface 122d of one engaging protrusion 122a and the first surface 122b of the other engaging protrusion 122a.

[0042] The moving body 13 will be described in detail with reference to FIGS. 2 and 6. FIG. 6 is a perspective view of the moving body 13. The moving body 13 is housed inside the screw barrel 12 and the front barrel 15. The outer periphery of the moving body 13 is close to the inner surfaces of the screw barrel 12 and the front barrel 15 that define the arrangement space of the moving body 13. "Close" refers to a state in which two objects are so close that they are touching. A part of the outer periphery of the moving body 13 may be in contact with a part of the inner surfaces. In this case, rattle and deformation of the moving body 13 in the arrangement space of the moving body 13 can be suppressed.

[0043] The moving body 13 is rod-shaped. The moving body 13 extends along the axial direction D1. The moving body 13 has a rod-shaped portion 13a located on the front side of the moving body 13. The rod-shaped portion 13a is arranged in the front through-hole 15b of the front tube 15. The rod-shaped portion 13a is arranged in a portion that overlaps with the third portion 152c of the front tube 15 in the axial direction D1 when the moving body 13 is at the rearmost position. The moving body 13 has a protrusion 13d that protrudes from the tip of the rod-shaped portion 13a. The outer diameter of the protrusion 13d is smaller than the outer diameter of the rod-shaped portion 13a. The moving body 13 has a protrusion 13e provided at the rear end of the moving body 13. The protrusion 13e has approximately the same shape as the protrusion 13d.

[0044] The moving body 13 has a male screw 13b extending rearward from the rod-shaped portion 13a. The male screw 13b is formed on the outer peripheral surface of the moving body 13. The male screw 13b extends around the axis of the moving body 13. The male screw 13b is threadedly engaged with the female screw 121a of the screw portion 121. When the screw tube 12 rotates relative to the moving body 13, the threading action between the male screw 13b and the female screw 121a causes the moving body 13 to move in the axial direction D1 with respect to the screw tube 12.

[0045] The movable body 13 has a groove 13c on its outer peripheral surface that extends along the axial direction D1. For example, the groove 13c extends from the front end of the rod-shaped portion 13a to the rear end of the male screw 13b. The groove 13c is recessed from the top surface of the male screw 13b toward the axis of the movable body 13. The radial length (depth) of the groove 13c is equal to the radial length (protrusion amount) of the male screw 13b, for example. A protrusion provided on the inner peripheral surface of the extension portion 152 of the front tube 15 fits into the groove 13c. The protrusion fits into the groove 13c, causing the movable body 13 to rotate synchronously with the front tube 15.

[0046] Piston 14 is disposed in front of moving body 13. Piston 14 has a generally cylindrical shape. Piston 14 has recess 14a located at the front end of piston 14. Recess 14a is recessed toward the rear. The rear end portion of applicator M is accommodated in recess 14a. Piston 14 has recess 14b located at the rear end of piston 14. Recess 14b is recessed toward the front. Protrusion 13d of moving body 13 fits into recess 14b. Piston 14 is movable in axial direction D1 relative to front tube 15. When moving body 13 moves forward, piston 14 and applicator M move forward together with moving body 13. At this time, applicator M that has moved forward is advanced from opening 15a of front tube 15.

[0047] When the dispensing container cartridge 10 is not attached to the container body 2 (described later), the screw tube 12 does not rotate synchronously with either the front tube 15 or the rear tube 16. Therefore, even if the front tube 15 or the rear tube 16, which are the parts of the dispensing container cartridge 10 that can be gripped by the user, are rotated about the axis of the dispensing container cartridge 10, the screw tube 12 does not rotate. Therefore, even if the front tube 15 or the rear tube 16 is rotated about the axis of the dispensing container cartridge 10, the screw tube 12 does not rotate relative to the moving body 13, and the moving body 13 does not move in the axial direction D1 relative to the screw tube 12. Furthermore, in the dispensing container cartridge 10, the engaging portion 122 is housed inside the tubular member 11. Therefore, the engaging portion 122 is less likely to come into contact with the user's fingers or objects. This prevents the applicator M from being dispensed through the opening 15a when the dispensing container cartridge 10 is not attached to the container body 2.

[0048] The dispensing container 1 will be described with reference to Figures 2 and 7. Figure 7 is a cross-sectional view of the dispensing container 1. The dispensing container 1 comprises a container body 2 and a dispensing container cartridge 10. The container body 2 has an outer tube member 3 and a connecting member 4. The outer tube member 3 is, for example, cylindrical. Inside the outer tube member 3, the outer tube member 3 has a front region R1 and a rear region R2 located rearward of the front region R1. The front region R1 communicates with the rear region R2. The rear portion of the dispensing container cartridge 10 is housed in the front region R1.

[0049] The outer tube member 3 has an internal female screw 3a. The female screw 3a is formed on the inner wall of the outer tube member 3 that defines the front region R1. The female screw 3a screws into a male screw portion 162c of the rear tube 16. The male screw portion 162c screws into the female screw 3a, making the tube member 11 of the dispensing container cartridge 10 detachable from the container body 2. This makes the dispensing container cartridge 10 detachable from the container body 2.

[0050] The rear region R2 accommodates the connecting member 4. The outer tubular member 3 has a groove 3b on its inner surface. For example, the outer tubular member 3 has multiple grooves 3b. More specifically, multiple grooves 3b extending in the axial direction D1 are provided on the inner wall of the outer tubular member 3 that defines the rear region R2. The multiple grooves 3b are aligned along the circumferential direction of the outer tubular member 3. The inner diameter of the outer tubular member 3 at the rear end of the rear region R2 is larger than the inner diameter of the outer tubular member 3 at the portion where the grooves 3b are provided. The outer tubular member 3 has an annular recess 3c on its inner surface. The annular recess 3c extends along the circumferential direction of the outer tubular member 3 in the rear region R2. The annular recess 3c is recessed radially outward of the outer tubular member 3.

[0051] The connecting member 4 will be described with reference to Figures 7 and 8. Figure 8 is a perspective view of the connecting member 4. The connecting member 4 extends in the axial direction D1. As an example, the connecting member 4 has a cylindrical shape. The connecting member 4 has an engaged portion 41 located on the front side of the connecting member 4, a tail plug 42 located on the rear side of the connecting member 4, and an elastic portion 43 located between the engaged portion 41 and the tail plug 42. The engaged portion 41 is provided at the end of the connecting member 4 on the engaging portion 122 side (front side).

[0052] The engaging portion 122 engages with the engaged portion 41. The engaged portion 41 has a shape corresponding to the engaging portion 122. Specifically, the engaged portion 41 has an engaged protrusion 41a that comes into contact with the engaging protrusion 122a (see FIG. 5). For example, the engaged portion 41 has a plurality of (for example, two) engaged protrusions 41a. The engaged protrusion 41a includes a fourth surface 41b that comes into contact with the first surface 122b, a fifth surface 41c that comes into contact with the second surface 122c, a sixth surface 41d that comes into contact with the third surface 122d, and a pressing surface 41e that presses the pressed surface 122e.

[0053] When viewed from the front, the sixth surface 41d, the fifth surface 41c, and the fourth surface 41b are arranged in this order clockwise. When viewed from the front, the fourth surface 41b, the fifth surface 41c, and the sixth surface 41d each form a part of a ring. The area of the fifth surface 41c is larger than the area of the fourth surface 41b and the area of the sixth surface 41d. The fourth surface 41b is, for example, perpendicular to the axial direction D1. The sixth surface 41d is, for example, perpendicular to the axial direction D1.

[0054] The fifth surface 41c extends from the fourth surface 41b along the circumferential direction of the connecting member 4 and also extends obliquely forward. The sixth surface 41d is located at the end of the fifth surface 41c opposite the fourth surface 41b. The pressing surface 41e is recessed in the axial direction D1 (rearward) from the end of the sixth surface 41d opposite the fifth surface 41c. The pressing surface 41e extends, for example, in the radial direction and the axial direction D1 of the connecting member 4. The pressing surface 41e is, for example, perpendicular to each of the fourth surface 41b and the sixth surface 41d. The pressing surface 41e is located between the sixth surface 41d of one engaged protrusion 41a and the fourth surface 41b of the other engaged protrusion 41a.

[0055] The tail plug 42 seals the opening located at the rear end of the outer tubular member 3. The tail plug 42 has, for example, a columnar portion and a flange located behind the columnar portion. The columnar portion is, for example, cylindrical, and the flange is disk-shaped. The outer diameter of the flange of the tail plug 42 is, for example, the same as the outer diameter of the outer tubular member 3. The outer diameter of the columnar portion of the tail plug 42 is, for example, the same as the inner diameter of the outer tubular member 3. The length in the axial direction D1 of the flange of the tail plug 42 is shorter than the length in the axial direction D1 of the columnar portion of the tail plug 42.

[0056] The elastic portion 43 is, for example, a spring that expands and contracts in the axial direction D1. The elastic portion 43 urges the engaged portion 41 forward. The elastic portion 43 urges the engaged portion 41 toward the engaging portion 122. The elastic portion 43 extends in a spiral shape around the axis of the connecting member 4. The elastic portion 43 has, for example, a double spiral structure.

[0057] The elastic portion 43 has a curved portion 43a and an inclined portion 43b. The curved portion 43a extends along the circumferential direction of the connecting member 4. The curved portion 43a is, for example, perpendicular to the axial direction D1. The curved portion 43a has an arc shape when viewed along the axial direction D1. The elastic portion 43 has a plurality of curved portions 43a. For example, two curved portions 43a are arranged in a cross section of the elastic portion 43 cut along a plane perpendicular to the axial direction D1. The two curved portions 43a are arranged at positions sandwiching the axis of the connecting member 4.

[0058] The elastic portion 43 has a row formed by a plurality of curved portions 43a aligned in the axial direction D1, and the number of rows is, for example, two. These two rows are arranged at positions sandwiching the axis of the connecting member 4. The inclined portions 43b are inclined with respect to both the circumferential direction of the connecting member 4 and the axial direction D1. The connecting member 4 has a plurality of inclined portions 43b. The inclined portions 43b are formed between a curved portion 43a and another curved portion 43a different from the curved portion 43a. More specifically, one end of the inclined portion 43b is connected to a curved portion 43a belonging to one of the rows. The other end of the inclined portion 43b is connected to a curved portion 43a belonging to the other row. The curved portion 43a to which one end of the inclined portion 43b is connected is located forward of the curved portion 43a to which the other end of the inclined portion 43b is connected.

[0059] The connecting member 4 has a first fitting portion 44 located between the engaged portion 41 and the elastic portion 43, a second fitting portion 45 located between the first fitting portion 44 and the elastic portion 43, a third fitting portion 46 located between the elastic portion 43 and the tail plug 42, and a fourth fitting portion 47 located between the third fitting portion 46 and the tail plug 42. The first fitting portion 44 has a cylindrical portion with an outer diameter larger than the outer diameter of the engaged portion 41 and multiple protrusions protruding from the outer peripheral surface of the cylindrical portion. Each protrusion is trapezoidal when viewed from the axial direction D1. Each protrusion fits into a groove 3b formed on the inner surface of the outer cylindrical member 3.

[0060] The outer contour of the second fitting portion 45 and the outer contour of the third fitting portion 46 each have, for example, the same shape as the outer contour of the first fitting portion 44. The protrusions on each of the second fitting portion 45 and the third fitting portion 46 fit into the groove 3b. Because the protrusions on the first fitting portion 44, the protrusions on the second fitting portion 45, and the protrusions on the third fitting portion 46 each fit into the groove 3b, the connecting member 4 rotates synchronously with the outer tube member 3. However, any one of the protrusions on the first fitting portion 44, the protrusions on the second fitting portion 45, and the protrusions on the third fitting portion 46 may fit into the groove 3b, and in this case too, the connecting member 4 can rotate synchronously with the outer tube member 3.

[0061] The fourth fitting portion 47 has a generally cylindrical shape. The fourth fitting portion 47 has an annular protrusion 47a located at the rear end of the fourth fitting portion 47. The outer diameter of the annular protrusion 47a is larger than the outer diameter of a portion of the fourth fitting portion 47 forward of the annular protrusion 47a. The annular protrusion 47a is fitted into the annular recess 3c. This allows the connecting member 4 to engage with the outer tube member 3 in the axial direction D1.

[0062] The connecting member 4 has a first reinforcing portion 48a located between the first fitting portion 44 and the second fitting portion 45, a second reinforcing portion 48b located between the third fitting portion 46 and the fourth fitting portion 47, and a third reinforcing portion 48c located between the fourth fitting portion 47 and the tail plug 42. The first reinforcing portion 48a has a cylindrical portion and a protruding portion that protrudes outward from the outer circumferential surface of the cylindrical portion. The first reinforcing portion 48a has multiple (four, for example) protruding portions. The tops of the protruding portions are located inside the outer contour of the first fitting portion 44 and the outer contour of the second fitting portion 45.

[0063] For example, the first reinforcing portion 48a has an X-shape. The second reinforcing portion 48b and the third reinforcing portion 48c have, for example, the same shape as the first reinforcing portion 48a. The apex of the protrusion of the second reinforcing portion 48b is located inside the outer contour of the third fitting portion 46 and the outer contour of the fourth fitting portion 47. The apex of the protrusion of the third reinforcing portion 48c is located inside the outer contour of the fourth fitting portion 47 and the outer contour of the tail plug 42.

[0064] The dispensing container cartridge 10 is attached to the container body 2 as follows. The rear tube 16 is inserted through the opening at the front end of the outer tube member 3. The male thread portion 162c of the rear tube 16 is threadedly engaged with the female thread 3a of the outer tube member 3. As the male thread portion 162c is threadedly engaged with the female thread 3a, the engaging portion 122 of the screw tube 12 approaches the engaged portion 41 of the connecting member 4, and the engaging portion 122 engages with the engaged portion 41. More specifically, the first surface 122b, the second surface 122c, the third surface 122d, and the pressed surface 122e of the engaging portion 122 (see FIG. 5) come into contact with the fourth surface 41b, the fifth surface 41c, the sixth surface 41d, and the pressed surface 41e of the engaged portion 41, respectively. This completes the attachment of the dispensing container cartridge 10 to the container body 2.

[0065] When the dispensing container cartridge 10 is attached to the container body 2, the engaging portion 122 of the dispensing container cartridge 10 engages with the engaged portion 41 of the container body 2 (connecting member 4) in the circumferential direction. The engaging portion 122 engages with the engaged portion 41 in the circumferential direction, so that the screw tube 12 of the dispensing container cartridge 10 can rotate synchronously in one direction with the container body 2 (outer cylinder member 3 and connecting member 4). Note that the screw tube 12 cannot rotate synchronously with the container body 2 in the opposite direction to the one direction.

[0066] The following describes dispensing container 1 when applicator M is dispensed. For example, when a user holds outer tube member 3 with one hand and pinches front tube 15 with the other hand while rotating outer tube member 3 in one direction relative to front tube 15, connecting member 4 rotates together with outer tube member 3 relative to front tube 15. When connecting member 4 rotates relative to front tube 15, screw tube 12 rotates together with connecting member 4 relative to front tube 15 and moving body 13. This relative rotation causes the screw engagement between male screw 13b and female screw 121a to work, as described above, and moves moving body 13 in axial direction D1 relative to screw tube 12. At this time, moving body 13 advances in axial direction D1 relative to screw tube 12, and applicator M is dispensed from opening 15a.

[0067] As described above, the screw tube 12 is not synchronously rotatable with the container body 2 in the opposite direction to the one direction, and therefore, even if the outer tube member 3 is rotated in the opposite direction relative to the front tube 15, the screw tube 12 does not rotate relatively. Therefore, in this embodiment, the applicator M is not pulled back rearward.

[0068] Next, the effects obtained from the dispensing container cartridge 10 and dispensing container 1 according to this embodiment will be described. In the dispensing container cartridge 10, a male screw 13b formed on the outer peripheral surface of the movable body 13 is screwed into a female screw 121a formed on the inner peripheral surface of the screw tube 12. This allows the movable body 13 to move forward relative to the screw tube 12, thereby moving the applicator M. In this dispensing container cartridge 10, the tubular member 11 has an engaging portion 122 therein that engages with the engaged portion 41 of the container body 2. Because the engaging portion 122 is provided inside the tubular member 11, it is possible to prevent the user's fingers or other objects from unintentionally coming into contact with the engaging portion 122.

[0069] Furthermore, when the dispensing container cartridge 10 is attached to the container body 2 and the engaging portion 122 engages with the engaged portion 41, the screw tube 12 becomes synchronously rotatable with the container body 2. That is, the screw tube 12 becomes synchronously rotatable with the container body 2 only when the engaging portion 122 provided inside the tubular member 11 engages with the engaged portion 41. This makes it possible to prevent the screw tube 12 from rotating when the dispensing container cartridge 10 is not attached to the container body 2. This makes it possible to prevent the user from unintentionally dispensing the applicator M.

[0070] The engaging portion 122 is provided on the screw tube 12. The male screw 13b formed on the outer peripheral surface of the movable body 13 screws into the female screw 121a formed on the inner peripheral surface of the screw tube 12, so the outer diameter of the screw tube 12 is larger than the outer diameter of the movable body 13. Therefore, compared to when the engaging portion is provided on the movable body 13, the strength of the engaging portion 122 can be increased, making the engaging portion 122 less likely to be damaged.

[0071] Engaging portion 122 is provided on the end face of screw barrel 12 opposite opening 15a of tubular member 11. When dispensing container cartridge 10 is attached to container body 2, engaging portion 122 can be engaged with engaged portion 41 by bringing the end face of screw barrel 12 into contact with engaged portion 41. Therefore, engaging portion 122 can be easily engaged with engaged portion 41.

[0072] Dispensing container 1 comprises dispensing container cartridge 10 and container body 2. Container body 2 has outer tube member 3 and connecting member 4 that rotates synchronously with outer tube member 3 inside outer tube member 3. Connecting member 4 has engaged portion 41 and elastic portion 43 that biases engaged portion 41 toward engaging portion 122. Engaged portion 41 is provided at the end of connecting member 4 on the engaging portion 122 side.

[0073] The connecting member 4 has an elastic portion 43 that urges the engaged portion 41 toward the engaging portion 122. Therefore, when engaging the engaging portion 122 with the engaged portion 41, the engaging portion 122 approaches the engaged portion 41 and the engaged portion 41 is urged toward the engaging portion 122, so that the engaging portion 122 can be easily brought into close contact with the engaged portion 41. Because the connecting member 4 rotates synchronously with the outer tube member 3, when torque is applied to the outer tube member 3, torque can be applied to the engaging portion 122 via the engaged portion 41 of the connecting member 4. This allows the applicator M to be advanced.

[0074] Next, a dispensing container cartridge and dispensing container according to a second embodiment will be described with reference to Figures 9 and 10. The configuration of the dispensing container cartridge and dispensing container according to the second embodiment is partially the same as the configuration of the dispensing container cartridge 10 and dispensing container 1 described above. Therefore, in the following, explanations that overlap with the explanations of the dispensing container cartridge 10 and dispensing container 1 will be omitted where appropriate.

[0075] Fig. 9 is a perspective view of dispensing container cartridge 10A according to the second embodiment. Fig. 10 is a cross-sectional view taken along line XX in Fig. 9. Dispensing container cartridge 10A comprises a tubular member 21, a screw tube 22, a moving body 23, a piston 24, and an applicator M. Tubular member 21 houses screw tube 22, a moving body 23, piston 24, and applicator M. Tubular member 21 comprises a front tube 25 and a rear tube 26 connected to front tube 25. Front tube 25 is formed with an opening 25a through which applicator M is dispensed.

[0076] The front tube 25 has a tapered portion 251 located on the front side of the front tube 25 and an extending portion 252 extending rearward from the rear end of the tapered portion 251. The extending portion 252 has an annular protrusion 252a protruding outward from the outer circumferential surface of the extending portion 252. The front tube 25 has a front through-hole 25b extending along the axial direction D1 and a rear through-hole 25c located rearward of the front through-hole 25b inside the front tube 25. The rear through-hole 25c communicates with the front through-hole 25b. The length of the front through-hole 25b in the axial direction D1 is longer than the length of the tapered portion 251 in the axial direction D1. The front tube 25 has a protrusion 253 protruding inward from the inner circumferential surface of the front tube 25 at the rear end of the front through-hole 25b. The front tube 25 has a pair of protrusions 253. The protrusion 253 protrudes radially inward from the front tube 25 and extends along the axial direction D1.

[0077] For example, both ends of rear tube 26 are open. Rear tube 26 is, for example, cylindrical. Rear tube 26 has an exposed portion 261 that is exposed when dispensing container cartridge 10A is attached to container body 2A (see FIG. 12), an attachment portion 262 that fits inside container body 2A, and a flange portion 263 that is located between exposed portion 261 and attachment portion 262. An annular recessed portion 261a that fits into annular protrusion 252a of front tube 25 is provided on the inner circumferential surface of exposed portion 261. Attachment portion 262 has a male threaded portion 262a that is located on the front side of attachment portion 262, and an extension portion 262b that extends rearward from the rear end of male threaded portion 262a.

[0078] The screw barrel 22 has a recess 22a extending rearward from the front end of the screw barrel 22. The screw barrel 22 has a screw portion 221 located on the front side of the screw barrel 22, an engaging portion 222 located on the rear side of the screw barrel 22, and a tube portion 223 located between the screw portion 221 and the engaging portion 222.

[0079] The screw portion 221 has a female screw 221a formed on its inner circumferential surface. The screw portion 221 is not engaged with the front tube 25, and therefore does not rotate synchronously with the front tube 25. The screw portion 221 has an annular recess on its outer circumferential surface that extends in the circumferential direction of the screw portion 221. An O-ring R is disposed in the annular recess.

[0080] The outer diameter of the tube portion 223 is larger than the outer diameter of the screw portion 221. The tube portion 223 is located rearward of the extending portion 252 of the front tube 25. The inner diameter of the portion of the recess 22a rearward of the female screw 221a is larger than the inner diameter of the female screw 221a. The screw tube 22 has a wall portion 22b that closes the internal space of the screw tube 22. The wall portion 22b is formed, for example, at the end of the screw tube 22 opposite to the opening 25a. For example, the wall portion 22b closes the internal space of the tube portion 223, and as an example, closes the rear end of the tube portion 223. The wall portion 22b defines the rear end of the recess 22a and closes the internal space of the screw tube 22.

[0081] Engaging portion 222 will be described with reference to Figures 10 and 11. Figure 11 is a rear perspective view of dispensing container cartridge 10A. Engaging portion 222 is provided at the rear end of screw barrel 22. Engaging portion 222 is provided on wall portion 22b. Engaging portion 222 is provided at the end of front barrel 25 opposite opening 25a. Engaging portion 222 is provided inside barrel member 21. Engaging portion 222 does not engage with rear barrel 26, and therefore does not rotate synchronously with rear barrel 26.

[0082] The engaging portion 222 has an engaging protrusion 222a that receives a force that rotates the screw barrel 22. For example, the engaging portion 222 has a plurality of (for example, three) engaging protrusions 222a. The engaging protrusion 222a has a first surface 222b, a second surface 222c, and a pressed surface 222d. The first surface 222b and the second surface 222c each form a part of a ring when viewed from the back surface of the screw barrel 22. The area of the second surface 222c is larger than the area of the first surface 222b. The first surface 222b is, for example, perpendicular to the axial direction D1. The first surface 222b is, for example, parallel to the wall portion 22b. The first surface 222b is located rearward of the wall portion 22b.

[0083] The second surface 222c extends from the first surface 222b along the circumferential direction of the engaging portion 222 and also extends obliquely forward. The pressed surface 222d is recessed in the axial direction D1 (forward) from an end of the first surface 222b opposite to the second surface 222c. The pressed surface 222d extends, for example, in the radial direction and axial direction D1 of the screw tube 22. The pressed surface 222d is, for example, perpendicular to each of the first surface 222b and the wall portion 22b. The second surface 222c extends from one edge of the first surface 222b in the circumferential direction of the screw tube 22, and the pressed surface 222d extends from the other edge of the first surface 222b in the circumferential direction of the screw tube 22.

[0084] The moving body 23 has a rod-shaped portion 23a, which is the front portion of the moving body 23, and a protrusion 23c connected to the tip of the rod-shaped portion 23a. The moving body 23 has a male screw 23b extending rearward from the rod-shaped portion 23a. The moving body 23 has a groove on its outer circumferential surface that extends along the axial direction D1. A protrusion 253 of the front tube 25 fits into the groove, causing the moving body 23 to rotate synchronously with the front tube 25. The piston 24 has a recess 24a recessed rearward at the front end of the piston 24, and a recess 24b recessed forward at the rear end of the piston 24.

[0085] When the dispensing container cartridge 10A is not attached to the container body 2A (described later), the screw tube 22 does not rotate synchronously with either the front tube 25 or the rear tube 26. Therefore, even if the front tube 25 or the rear tube 26 is rotated about the axis of the dispensing container cartridge 10A, the screw tube 22 does not rotate. Therefore, even if the front tube 25 or the rear tube 26 is rotated about the axis of the dispensing container cartridge 10A, the moving body 23 does not move in the axial direction D1 relative to the screw tube 22. In the dispensing container cartridge 10A, as described above, the engaging portion 222 is housed inside the tubular member 21. Therefore, the engaging portion 222 is less likely to come into contact with the user's fingers or other objects. This prevents the applicator M from being dispensed through the opening 25a when the dispensing container cartridge 10A is not attached to the container body 2A.

[0086] The dispensing container 1A will be described with reference to Figure 12. Figure 12 is a cross-sectional view of the dispensing container 1A. The dispensing container 1A comprises a container body 2A and a dispensing container cartridge 10A. The container body 2A has an outer tube member 5 and a connecting member 6. The outer tube member 5 has a front region R3 and a rear region R4 located rearward of the front region R3 within the outer tube member 5. A female screw 5a is provided on the inner wall of the outer tube member 5 that defines the front region R3. The female screw 5a screws into a male screw portion 262a of the rear tube 26. The outer tube member 5 has a groove 5b and an annular recess 5c on its inner surface.

[0087] The connecting member 6 will be described with reference to Figures 12 and 13. Figure 13 is a perspective view of the connecting member 6. The connecting member 6 extends in the axial direction D1. As an example, the connecting member 6 is rod-shaped. The connecting member 6 has an engaged portion 61 located on the front side of the connecting member 6, a tail plug 62 located on the rear side of the connecting member 6, an elastic portion 63 located between the engaged portion 61 and the tail plug 62, an extending portion 64 extending rearward from the rear end of the engaged portion 61, a first fitting portion 65 located between the extending portion 64 and the elastic portion 63, and a second fitting portion 66 located between the elastic portion 63 and the tail plug 62.

[0088] The engaged portion 61 is provided at the end of the connecting member 6 on the engaging portion 222 side (front side). The engaging portion 222 engages with the engaged portion 61. The engaged portion 61 has a shape corresponding to the engaging portion 222. Specifically, the engaged portion 61 has an engaged protrusion 61a that comes into contact with the engaging protrusion 222a (see FIG. 11). For example, the engaged portion 61 has multiple (for example, three) engaged protrusions 61a. The engaged protrusion 61a includes a third surface 61b that comes into contact with the wall portion 22b, a fourth surface 61c that comes into contact with the second surface 222c, a bottom surface 61d that comes into contact with the first surface 222b, and a pressing surface 61e that presses the pressed surface 222d. When viewed from the front, the third surface 61b and the fourth surface 61c each form a part of a ring. The area of the fourth surface 61c is larger than the area of the third surface 61b. The third surface 61b is, for example, perpendicular to the axial direction D1.

[0089] The fourth surface 61c extends from the third surface 61b along the circumferential direction of the connecting member 6 and also extends obliquely rearward. The pressing surface 61e is recessed in the axial direction D1 (rearward) from the end of the third surface 61b opposite to the fourth surface 61c. The pressing surface 61e extends, for example, in the radial direction and the axial direction D1 of the connecting member 6.

[0090] The tail plug 62 seals the opening located at the rear end of the outer tubular member 5. The tail plug 62 has, for example, a columnar portion and a flange located behind the columnar portion. The tail plug 62 has an annular protrusion 62a on the outer periphery of the columnar portion. The annular protrusion 62a is fitted into the annular recess 5c. The extension portion 64 has a rod shape (e.g., a round rod shape). The outer diameter of the extension portion 64 is smaller than the outer diameter of the engaged portion 61 and the outer diameter of the first fitting portion 65. The first fitting portion 65 has a tubular shape (e.g., a cylindrical shape). The first fitting portion 65 has a plurality of protrusions 65a on its outer circumferential surface. Each of the plurality of protrusions 65a fits into a corresponding one of the plurality of grooves 5b of the outer tubular member 5. As the protrusions 65a fit into the grooves 5b, the connecting member 6 rotates synchronously with the outer tubular member 5. The protrusion 65a is movable within the groove 5b along the axial direction D1. The engaged portion 61, the extending portion 64, and the first fitting portion 65 are movable in the axial direction D1.

[0091] The elastic portion 63 is connected to the first fitting portion 65 and the second fitting portion 66. The elastic portion 63 is, for example, a spring that expands and contracts in the axial direction D1. The elastic portion 63 urges the engaged portion 61 forward. The elastic portion 63 urges the engaged portion 61 toward the engaging portion 222. The elastic portion 63 extends spirally around the axis of the connecting member 6.

[0092] The second fitting portion 66 has a plurality of protrusions 66a. The protrusions 66a extend in the axial direction D1. The protrusions 66a protrude radially outward from the connecting member 6. Each of the plurality of protrusions 66a fits into the groove 5b. The second fitting portion 66 is connected to the tail plug 62. As the protrusions 66a fit into the groove 5b, the second fitting portion 66 and the tail plug 62 rotate synchronously with the outer cylindrical member 5.

[0093] 10, 12, and 13, the dispensing container cartridge 10A will be described when it is attached to the container body 2A. First, rear tube 26 of dispensing container cartridge 10A is inserted through the opening at the front end of outer tube member 5. Male thread portion 262a of rear tube 26 is threadedly engaged with female thread 5a of outer tube member 5. As male thread portion 262a is threadedly engaged with female thread 5a, engaging portion 222 of screw tube 22 approaches engaged portion 61 of connecting member 6, and engaging portion 222 engages with engaged portion 61. More specifically, first surface 222b, second surface 222c, wall portion 22b, and pressed surface 222d of engaging portion 222 (see FIG. 11) come into contact with bottom surface 61d, fourth surface 61c, third surface 61b, and pressing surface 61e of engaged portion 61, respectively. This completes the attachment of dispensing container cartridge 10A to container body 2A.

[0094] When the dispensing container cartridge 10A is attached to the container body 2A, the engaging portion 222 of the dispensing container cartridge 10A circumferentially engages with the engaged portion 61 of the container body 2A (connecting member 6). The engaging portion 222 engages with the engaged portion 61 circumferentially, allowing the screw tube 22 of the dispensing container cartridge 10A to rotate synchronously with the container body 2A (outer cylinder member 5 and connecting member 6).

[0095] Dispensing container 1A will be described when applicator M is being dispensed. For example, when a user holds outer tube member 5 with one hand and pinches front tube 25 with the other hand, and rotates outer tube member 5 in one direction relative to front tube 25, connecting member 6 rotates together with outer tube member 5 relative to front tube 25. When connecting member 6 rotates relative to front tube 25, screw tube 22 rotates together with connecting member 6 relative to front tube 25 and moving body 23. This relative rotation causes the screwing action between male screw 23b and female screw 221a to work, as described above, and moves moving body 23 in axial direction D1 relative to screw tube 22. At this time, moving body 23 advances in axial direction D1 relative to screw tube 22, and applicator M is dispensed from opening 25a.

[0096] Next, the effects obtained from dispensing container cartridge 10A and dispensing container 1A according to this embodiment will be described. Screw barrel 22 has wall 22b that closes the internal space of screw barrel 22. In this case, wall 22b closes the internal space of screw barrel 22, thereby improving the airtightness of the internal space of screw barrel 22. Furthermore, by providing wall 22b that closes the internal space of screw barrel 22, the strength of screw barrel 22 can be sufficiently improved. Note that, unlike dispensing container cartridge 10 described above (see FIG. 2), screw barrel 12 does not necessarily have to have a wall that closes the internal space. In other words, the internal space of screw barrel 12 may be open. In this case, there is an advantage in that the formability of screw barrel 12 can be improved.

[0097] The above describes embodiments of the dispensing container cartridge and dispensing container according to the present disclosure. However, the dispensing container cartridge and dispensing container according to the present disclosure are not limited to the above-described embodiments, and may be further modified within the scope of the gist set forth in the claims. In other words, the shape, size, material, number, and arrangement of each part of the dispensing container cartridge and dispensing container according to the present disclosure may be modified as appropriate within the scope of the above-described gist.

[0098] For example, dispensing container 1A may have a core provided inside elastic portion 63. This core may have a guide portion that moves engaged portion 61, extending portion 64, and first fitting portion 65 along axial direction D1.

[0099] In the above-described embodiment, the dispensing container 1 has been described in which the screw tube 12 has the engaging portion 122. However, the dispensing container may have the engaging portion in the movable body 13, rather than the screw tube 12. In this case, the engaging portion may be provided at the rear end of the movable body 13. The female screw that screws with the male screw 13b of the movable body 13 may be provided in a through hole of the front tube 15. The female screw may be provided only near the front end of the male screw 13b, or may be provided so as to screw with the entire male screw 13b. Furthermore, in the above-described embodiment, the dispensing container 1 has been described in which the screw tube 12 is rotatable in one direction with the container body 2, but is not rotatable in the opposite direction to the one direction, and the applicator M is not retracted backward. However, the screw tube 12 may be rotatable in both directions with the container body 2, that is, in one direction and the opposite direction to the one direction, so that the applicator M can be retracted forward and retracted backward.

[0100] In the embodiment described above, the dispensing container 1 has been described in which the tubular member 11 and the screw tube 12 are configured as separate members. However, the dispensing container 1 may have a member in which the tubular member 11 and the screw tube 12 are integrated. This member may have an opening through which the applicator M is dispensed. As an example, the dispensing container 1 may have a member in which the front tube 15 of the tubular member 11 and the screw tube 12 are integrated. This member may be configured as a separate member from the rear tube 16. This member may be formed at the front end of the member and may have an opening through which the applicator M is dispensed.
