[Figure 11] Figure 1 is a cross-sectional view of a core material dispensing container, showing the state of the core material dispensing container when the core material is being replaced. [Modes for carrying out the invention]

[0010] The following describes a core material dispensing container according to one embodiment of the present invention, with reference to the drawings.

[0011] Figure 1 is a cross-sectional view of a core material dispensing container 1 according to one embodiment of the present invention, shown from the front. The cross-sectional view is shown in the state before use, with the core material loaded. Figure 2 shows the core material dispensing container 1 from the side.

[0012] In the figure, the symbol O represents the central axis of the core material dispensing container 1. In this embodiment, "axial direction" refers to the direction extending parallel to the central axis O of the core material dispensing container 1 (hereinafter also simply referred to as "central axis O"). In this embodiment, "radial direction" refers to the direction perpendicular to the axial direction. Furthermore, in this embodiment, the side of the radial direction closer to the central axis is also called the radially inner direction, and conversely, the side farther from the central axis is also called the radially outer direction. In addition, "circumferential direction" refers to the circumferential direction around the central axis O.

[0013] Furthermore, in the present embodiment, the lower side refers to the side where the bottom 7 of the core material feeding container 1 is located. Also, in the present embodiment, the upper side refers to the side where the feeding port A of the core material feeding container 1 is located, or in other words, the side opposite to the side where the bottom 7 of the core material feeding container 1 is located.

[0014] In the present embodiment, the core material C has a non-circular cross-sectional shape (a cross-sectional shape perpendicular to the axial direction). Examples of the non-circular shape include a flat shape. In the present embodiment, the core material C has an elliptical cross-sectional shape. In FIG. 1, the core material C is shown such that the long axis of the elliptical shape extends in the left-right direction of the drawing. Also, in FIG. 2, the core material C is shown such that the short axis of the elliptical shape extends in the left-right direction of the drawing. Here, in the present embodiment, the long axis direction refers to the direction in which the long axis of the elliptical shape extends. Also, in the present embodiment, the short axis direction refers to the direction in which the short axis of the elliptical shape extends.

[0015] The core material feeding container 1 includes a middle plate 22 to which the core material C can be attached, an inner cylinder 3 in which the middle plate 22 is slidably accommodated, an outer cylinder 4 in which the inner cylinder 3 is rotatably accommodated, a shoulder member 5 removably attached to the upper end portion of the inner cylinder 3 and rotatable together with the inner cylinder 3, and a mounting member 21 fixed to the core material C. In addition, the core material feeding container 1 includes a bottom 7 to which the inner cylinder 3 is rotatably attached.

[0016] Referring to FIG. 2, the middle plate 22 includes guide protrusions 23. The inner cylinder 3 includes guide holes 3c through which the guide protrusions 23 of the middle plate 22 penetrate and slidably guide the guide protrusions 23. The outer cylinder 4 includes spiral grooves 4a in which the guide protrusions 23 of the middle plate 22 can slide.

[0017] In this embodiment, the inner cylinder 3 has a circular cross-sectional shape. The central axis of the inner cylinder 3 is arranged on the same axis as the central axis О together with the central axis of the bottom 7. The guide hole 3c is a through-hole that penetrates the inner cylinder 3 in the radial direction. Thereby, the guide projection 23 of the middle plate 22 can project outward in the radial direction of the inner cylinder 3 through the guide hole 3c. The guide hole 3c extends in the axial direction. Thereby, the middle plate 22 can be slid in the axial direction along the guide hole 3c of the inner cylinder 3. In particular, in this embodiment, the guide hole 3c is open at the lower end of the inner cylinder 3. Thereby, the middle plate 22 can be easily inserted into the inner cylinder 3 by passing the guide projection 23 through the lower end opening of the guide hole 3c into the guide hole 3c.

[0018] In addition, in this embodiment, the inner cylinder 3 is rotatably attached to the bottom 7. In this embodiment, the bottom 7 includes a bottom body 7a and an insertion cylinder 7b that extends upward from the upper end of the bottom body 7a. The insertion cylinder 7b can be inserted into the inner cylinder 3 from the lower end opening of the inner cylinder 3. In this embodiment, an annular convex portion 7d is provided on the outer peripheral surface of the insertion cylinder 7b. In this embodiment, the annular convex portion 7d extends annularly in the circumferential direction. Also, in this embodiment, an annular concave portion 3d is provided on the inner peripheral surface of the inner cylinder 3. In this embodiment, the annular concave portion 3d extends annularly in the circumferential direction. In this embodiment, the annular convex portion 7d is held so as to restrict the vertical movement with respect to the annular concave portion 3d and allow the circumferential movement. Thereby, the inner cylinder 3 can be rotated in the circumferential direction with respect to the bottom 7.

[0019] Furthermore, in this embodiment, the outer cylinder 4 also has a circular, annular cross-sectional shape. The central axis of the outer cylinder 4 is also located on the same axis as the central axis O. In this embodiment, the outer cylinder 4 is non-rotatably attached to the bottom 7. In this embodiment, the lower end of the outer cylinder 4 is provided with a plurality of fitting protrusions 4c spaced apart in the circumferential direction. Furthermore, in this embodiment, the bottom body 7a of the bottom 7 is provided with fitting recesses 7c that can be fitted with the fitting protrusions 4c of the outer cylinder 4. In this embodiment, the outer cylinder 4 is non-rotatably attached to the bottom 7 by fitting its fitting protrusions 4c into the fitting recesses 7c of the bottom 7. In other words, in this embodiment, the outer cylinder 4 is integrally attached to the bottom 7. As a result, the inner cylinder 3 can rotate inside the outer cylinder 4 relative to the outer cylinder 4 and the bottom 7.

[0020] In addition, in this embodiment, the helical groove 4a is formed on the inner circumferential surface of the outer cylinder 4. The helical groove 4a extends spirally around the central axis O in the axial direction. This allows the guide projection 23 of the inner plate 22 to slide spirally in the axial direction while rotating circumferentially along the helical groove 4a. On the other hand, the guide projection 23 of the inner plate 22 is constrained to slide in the axial direction by the guide hole 3c of the inner cylinder 3. Therefore, the inner plate 22 can move axially along the guide hole 3c by rotating the inner cylinder 3.

[0021] In addition, a shoulder member 5 is non-rotatably attached to the upper end of the inner cylinder 3. Therefore, the middle plate 22 can move axially along the guide hole 3c by rotating the shoulder member 5 in the circumferential direction.

[0022] In this embodiment, the shoulder member 5 comprises an annular flange 5a that abuts against or is close to the upper end of the inner cylinder 3, a neck 5b that extends upward from the inner circumference of the annular flange 5a, and an operating cylinder 5c that extends downward from the outer circumference of the annular flange 5a. In this embodiment, the annular flange 5a extends in an annular shape in the circumferential direction. In this embodiment, the neck 5b is a cylindrical portion that extends in the axial direction. Furthermore, in this embodiment, the operating cylinder 5c surrounds the upper end of the outer cylinder 4 from the radially outer side, thereby allowing it to be operated from the outside of the outer cylinder 4.

[0023] In this embodiment, the upper outer edge 3a of the inner cylinder 3 is configured as an annular flange portion that protrudes radially outward. In this embodiment, the inner circumferential surface of the operating cylinder 5c is provided with a retaining projection 5e that prevents the upper outer edge 3a of the inner cylinder 3 from coming off. In this embodiment, the retaining projection 5e extends annularly in the circumferential direction. In this embodiment, the upper outer edge 3a of the inner cylinder 3 is fitted and held between the annular flange 5a of the shoulder member 5 and the retaining projection 5e. As a result, the shoulder member 5 is prevented from coming off the inner cylinder 3.

[0024] In addition, in this embodiment, a plurality of notches 3e are formed on the upper outer edge 3a of the inner cylinder 3 at intervals in the circumferential direction. Furthermore, in this embodiment, a plurality of bulges 5d are formed on the shoulder member 5 at intervals in the circumferential direction. In this embodiment, the bulges 5d are fitted into the notches 3e. As a result, the shoulder member 5 is attached to the inner cylinder 3 in a way that prevents rotation. Therefore, the shoulder member 5 can be rotated together with the inner cylinder 3.

[0025] Figure 3 shows the shoulder member together with the dispensing opening member from above. Figure 4 is a cross-sectional view of XX in Figure 3. Cross-section XX is a cross-section that includes the central axis O and extends in the direction of the long axis.

[0026] The core material dispensing container 1 is further equipped with a dispensing opening A and a dispensing opening member 6 that is rotatably attached to the shoulder member 5. The dispensing opening A is a through hole through which the core material C dispensed from the core material dispensing container 1 is dispensed so as to protrude to the outside. As shown in Figure 3, in this embodiment, the planar shape (cross-sectional shape) of the dispensing opening A is non-circular, matching the cross-sectional shape of the core material C. In other words, in this embodiment, the cross-sectional shape of the dispensing opening A is elliptical, matching the cross-sectional shape of the core material C.

[0027] Referring to Figure 4, in this embodiment, the dispensing opening member 6 comprises an annular flange 6a positioned at the upper end of the neck 5b of the shoulder member 5, a nozzle portion 6b extending upward from the inner circumference of the annular flange 6a, and a mounting cylinder 6c extending downward from the lower surface of the annular flange 6a. The mounting cylinder 6c can be inserted into the neck 5b through the upper end opening of the shoulder member 5 (the upper end opening of the neck 5b). In this embodiment, an annular projection 6d is provided on the outer circumferential surface of the mounting cylinder 6c. In this embodiment, the annular projection 6d extends in an annular shape in the circumferential direction. Also in this embodiment, an annular recess 5f is provided on the inner circumferential surface of the neck 5b of the shoulder member 5. In this embodiment, the annular recess 5f extends in an annular shape in the circumferential direction. In this embodiment, the annular projection 6d is held so as to be movable in the circumferential direction relative to the annular recess 5f. This allows the dispensing opening member 6 to be rotated relative to the shoulder member 5.

[0028] Furthermore, as shown in Figure 2, for example, the inner tray 22 is equipped with a mounting portion S to which the mounting member 21 is detachably attached.

[0029] In this embodiment, the mounting member 21 comprises a connecting portion 21a positioned below the core material C, and two arm portions 21b extending upward from the connecting portion 21a and fixed to the lower end of the core material C. In this embodiment, the two arm portions 21b are integrally formed with respect to the connecting portion 21a. As shown in Figure 2, the mounting member 21 has a U-shaped cross-section in a cross-sectional view including the central axis O. The mounting member 21 is made of, for example, resin or metal. The mounting member 21 can be formed, for example, by injection molding or press working (bending). In this embodiment, as shown in Figure 2, the mounting member 21 is fixed in the direction of the short axis of the core material C. The mounting member 21 can be fixed to the core material C, for example, by the two arm portions 21b clamping the lower end of the core material C. Alternatively, the mounting member 21 can be fixed to the core material C by integrally forming the core material C with the mounting member 21 as an insert.

[0030] Furthermore, as shown in Figure 1, in this embodiment, the inner tray 22 includes a partition portion 22a positioned below the mounting member 21, and two arm portions 22b that extend upward from the partition portion 22a and clamp the lower end of the core material C.

[0031] Figure 5 shows two examples of core material C being removed. The upper right side of Figure 5 shows an unused core material C. In this figure, the mounting member 21 is fixed to the lower end of the core material C. The upper left side of Figure 5 shows a used core material C. In this figure as well, the mounting member 21 is fixed to the lower end of the core material C. Furthermore, the lower side of Figure 5 shows the state in which the mounting member 21 of the core material C is attached to the inner tray 22, viewed from above.

[0032] The mounting portion S provided on the inner plate 22 can be an intermittent portion or a recess provided on the inner plate 22. The mounting portion S allows the mounting member 21 of the core material C to be fitted into the mounting portion S, thereby allowing the mounting member 21 to be removably attached to the inner plate 22. In this embodiment, the mounting portion S is formed between two arm portions 22b provided on the inner plate 22.

[0033] As shown in the lower part of Figure 5, in this embodiment, the mounting portion S is formed by a gap formed between two arm portions 21b provided on the middle plate 22. Specifically, in this embodiment, the mounting portion S is the gap formed between the opposing side surfaces 22s of the two arm portions 22b provided on the middle plate 22. In this embodiment, when the mounting member 21 is mounted on the mounting portion S, the side surfaces 21s of the arm portions 21b provided on the mounting member 21 are in contact with or close to the side surface 22s of the arm portion 22b provided on the middle plate 22 that is opposite to the said side surface 21s. Specifically, the mounting member 21 is attached to the middle plate 22 by fitting (press-fitting) it into the gap formed between the two arm portions provided on the middle plate 22. Therefore, in this embodiment, the mounting member 21 can be removed from between the two arms 22b together with the core material C by lifting it with a force greater than the fitting force (pressure force) with the two arms 22b provided on the middle plate 22. Note that in the drawing located at the bottom of Figure 5, the mounting part S is shown to be wider than the arms 21b of the mounting member 21, creating a gap, in order to make the explanation easier to understand.

[0034] Figure 6 is a plan view of the inner tray 22 shown from above. Figure 7 is a cross-sectional view of Figure 6 at point XX. Furthermore, Figure 8 is a cross-sectional view of Figure 6 at point YY. The YY section is a cross-section that includes the central axis O and extends in the direction of the short axis. In addition, Figure 9 is a bottom view of the inner tray 22 shown from below.

[0035] Referring to Figures 6 to 8, in this embodiment, the inner tray 22 has two arms 22b extending upward from the upper end of the partition 22a. In this embodiment, the two arms 22b are positioned opposite each other across the central axis O. In this embodiment, the core material C is held between the two arms 22b of the inner tray 22. Furthermore, in this embodiment, the inner surfaces (radially inner surfaces) of the two arms 22b are provided with locking projections 22c that abut against or are close to the core material C and hold the core material C. As a result, the core material C is fixed to the inner tray 22.

[0036] In addition, the inner tray 22 has two legs 22d extending downward from the lower surface of the partition 22a. In this embodiment, the two legs 22d are positioned opposite each other across the central axis O, as shown in Figure 9. In this embodiment, the guide projection 23 is provided on the outer surface (radial outer surface) of the leg 22d.

[0037] Referring to Figure 9, in this embodiment, the partition portion 22a is a perfect circle when viewed from the bottom (plan view).

[0038] In this embodiment, the two legs 22d are formed by cutting out cylinders of the same diameter as the circular partition 22a on both sides of the central axis, as shown in Figure 9. In other words, in this embodiment, the two legs 22d have a curved shape of a circular form. In this embodiment, the two legs 22d are positioned to align with the guide projection 23 (positions aligned in the YY cross-sectional direction).

[0039] Furthermore, referring to Figure 6, in this embodiment, the two arm portions 22b are based on an elliptical cylindrical shape in which the major axis end is in contact with the circular partition portion 22a, and are formed by cutting out the cylindrical shape on both minor axis sides with respect to the central axis O. In other words, in this embodiment, the two arm portions 22b have a curved shape in the major axis portion of the ellipse. In this embodiment, the two arm portions 22b are positioned perpendicular to the position where they align with the guide projection 23 (positions where they align in the XX cross-sectional direction).

[0040] Next, we will explain an example of how to use the core material dispensing container 1, referring to the drawings.

[0041] First, we will explain an example of the operation of dispensing core material C from core material dispensing container 1, and an example of the operation of loading core material C into said core material dispensing container 1.

[0042] Figures 1 and 2 show the state before the core material dispensing container 1 is used. In this embodiment, the core material dispensing container 1 is equipped with an overcap 8. The overcap 8 is detachably attached to the neck 5b of the shoulder member 5. Therefore, in this embodiment, the user first removes the overcap 8 from the shoulder member 5.

[0043] Next, the user holds the outer cylinder 4 with one hand and uses the other hand to rotate the operating cylinder 5c of the shoulder member 5 to one side in the circumferential direction. As a result, the middle plate 22, which is constrained by the guide hole 3c of the inner cylinder 3, rotates along the helical groove 4a of the outer cylinder 4 and moves axially (up and down) inside the inner cylinder 3 along the extending direction of the guide hole 3c. In other words, the core material C rotates along the helical groove 4a relative to the outer cylinder 4 together with the middle plate 22 and moves up and down along the guide hole 3c relative to the inner cylinder 3 and shoulder member 5, thereby being fed out upward. At this time, in this embodiment, the feeding opening member 6 is rotatable relative to the shoulder member 5. This makes it possible to suppress damage to the core material C even if circumferential play occurs in the core material C. Note that the feeding opening member 6 may be assembled so as not to rotate relative to the shoulder member 5, or the feeding opening member 6 and the shoulder member 5 may be formed as one unit.

[0044] Figure 10 shows a cross-section of the core material dispensing container 1 with the core material C dispensed out. As shown in Figure 10, with the core material dispensing container 1, by rotating the shoulder member 5 to one side in the circumferential direction relative to the outer cylinder 4, the core material C, which has an elliptical cross-sectional shape, can be made to protrude from the dispensing opening A without deforming it. This allows the user to apply the core material C dispensed from the core material dispensing container 1 to the desired area.

[0045] After using the core material C, the operating cylinder 5c of the shoulder member 5 is moved in the circumferential direction, etc. The core material C is rotated to one side (i.e., the opposite side from when it is being dispensed). This causes the core material C to be retracted downwards along with the inner tray 22. This allows the core material C to be lowered and retracted towards the bottom 7. Therefore, with the core material dispensing container 1, just as during dispensing, the core material C can be retracted from the dispensing opening A and housed inside the core material dispensing container 1 without deforming the core material C. In this embodiment, the initial state shown in Figure 1 can be returned by putting the overcap 8 back on after use.

[0046] Next, we will explain an example of how to replace core material C, and an example of how to use core material C that has been removed as a result of such replacement.

[0047] Figure 11 shows a cross-sectional view of the core material dispensing container 1 when the core material C is replaced.

[0048] When replacing the core material C, the inner tray 22 is extended further upward from the state shown in Figure 10, causing the entire arm portion 22b of the inner tray 22 to protrude from the upper end of the inner cylinder 3. As a result, the mounting member 21, together with the core material C, protrudes from the upper end of the inner cylinder 3. Next, as shown in Figure 11, the shoulder member 5 is removed from the inner cylinder 3 together with the extension opening member 6. As a result, as shown in Figure 11, the mounting member 21, positioned between the two arm portions 22b, can be exposed to the outside from the upper end of the inner cylinder 3. This allows the user to grasp and pull up the arm portion 21b of the mounting member 21 that is exposed between the two arm portions 22b provided on the inner tray 22. As a result, the shortened core material C can be removed together with the mounting member 21, as shown on the left side of the drawing in Figure 5. However, according to this embodiment, after removing the shoulder member 5 together with the dispensing opening member 6, the core material C may be dispensed using the upper outer edge 3a of the inner cylinder 3 until the mounting member 21 positioned between the two arm portions 22b is exposed from the upper end of the inner cylinder 3.

[0049] The shortened core material is configured as an independent core material C equipped with a mounting member 21, as shown on the left side of the drawing in Figure 5. This allows the shortened core material C to be used further by using the mounting member 21 as a handle. Specifically, the user can apply the core material C to the desired area by using the arm portion 21b of the mounting member 21 as a holding part. In this case, since the mounting member 21 is used as a handle, the user can use the shortened core material C without getting their hands dirty.

[0050] On the other hand, a new core material C can be attached to the inner tray 22 of the core material dispensing container 1 from which the shortened core material C has been removed, as shown on the right side of the drawing in Figure 5. In this case as well, the new core material C is configured as an independent core material C equipped with a mounting member 21. This allows the user to attach the new core material C to the inner tray 22 without getting their hands dirty by using the mounting member 21 as a handle. According to this embodiment, after attaching the new core material C via the mounting member 21, the new core material C can be stored inside the core material dispensing container 1 by passing the core material C through the dispensing opening A of the dispensing opening member 6 and reattaching the shoulder member 5 to the inner cylinder 3, thereby using the shoulder member 5. This allows the new core material C to be dispensed from the core material dispensing container 1 and used again. Alternatively, according to this embodiment, after attaching a new core material C via the mounting member 21, the core material C can be housed inside the inner cylinder 3 by using the upper outer edge 3a of the inner cylinder 3, and then the shoulder member 5 can be attached to the inner cylinder 3 together with the dispensing opening member 6.

[0051] The core material dispensing container 1 uses a dispensing mechanism with a middle tray 22, an inner cylinder 3, and an outer cylinder 4, allowing for stable dispensing of the core material C. This suppresses the occurrence of core misalignment. Furthermore, with the core material dispensing container 1, the core material C can be easily replaced by simply dispensing the middle tray 22 and then setting the mounting member 21 attached to the new core material C onto the middle tray 22. In addition, with the core material dispensing container 1, the mounting member 21 can be used as a handle, preventing the user from getting their hands dirty when replacing the core material C.

[0052] In addition, with the core material dispensing container 1, since the mounting member 21 is attached to the core material C, the replaced core material C can be used as is with the mounting member 21 as a handle. This allows the core material dispensing container 1 to use up the removed core material C completely. Furthermore, in this case, since the mounting member 21 can be used as a handle, the user does not get their hands dirty when using the core material C.

[0053] Furthermore, in this embodiment, the mounting member 21 has two arm portions 21b connected via a connecting portion 21a and fixed to the core material C, and the mounting member 21 is detachably attached to a mounting portion S formed between two arm portions 22b provided on the inner plate 22. In this case, the core material C can be replaced with a simple configuration.

[0054] The above describes a core material dispensing container 1 according to one embodiment of the present invention. However, the present invention is not limited to the above embodiment and can be modified in various ways within the scope described in the claims. Examples of core material C include, but are not limited to, stick-shaped cosmetics such as eyeliner, eyebrow pencil, lipstick, and lip gloss. [Explanation of Symbols]
