Description

[Technical Field]

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

[0002] A known container for storing stick-shaped contents such as lipstick, lip balm, or stick-type glue is a dispensing container that can raise an inner tray by rotating a lower operating body, and dispense the stick-shaped contents held by the inner tray from an upper opening (see, for example, Patent Documents 1 and 2).

[0003] In this type of dispensing container, the inner tray is usually shaped like a bottomed cylinder, with a bottom wall that supports the bottom of the contents and a peripheral wall that surrounds the bottom wall and holds the lower outer peripheral surface of the contents, so that it can securely hold the rod-shaped contents. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Utility Model Application Publication No. 63-062016 [Patent Document 2] Japanese Patent Application Laid-Open No. 2013-208154 Summary of the Invention [Problem to be solved by the invention]

[0005] In this type of dispensing container, the height of the contents gradually decreases with continued use. However, once it reaches the top edge of the peripheral wall, it becomes difficult to use any more of the contents, and a relatively large amount of the contents remains inside the peripheral wall.

[0006] In view of the above, an object of the present invention is to provide a dispensing container that can reduce the amount of content that remains unused. [Means for solving the problem]

[0007] The present invention provides a movable body comprising: an outer cylinder having a threaded portion formed on its inner peripheral surface; an inner cylinder rotatably housed within the outer cylinder and having a slit formed along the axial direction; a middle plate portion slidably housed within the inner cylinder along the axial direction, the upper end of which serves as a tray for supporting contents, the tray having a through hole formed therein, and a protrusion formed on the peripheral wall portion that protrudes radially outward and can be threadedly engaged with the threaded portion of the outer cylinder through the slit of the inner cylinder; and a movable body housed within the middle plate portion slidably along the axial direction of the middle plate portion, the protrusion being protruding from the through hole of the middle plate portion and being embedded in the contents supported by the tray, and a flange portion formed radially outward from the lower end of the protrusion. The protrusion has a cylindrical peripheral wall and is formed hollow, and a communication hole is formed in the peripheral wall of the protrusion, and the content supported by the tray outside the peripheral wall of the protrusion and the content provided inside the peripheral wall of the protrusion are connected via the communication hole. It is characterized by being a dispensing container.

[0009] Also, The present invention provides a movable body comprising an outer tube having a threaded portion formed on its inner peripheral surface, an inner tube rotatably housed within the outer tube and having a slit formed along the axial direction, a middle plate portion slidably housed within the inner tube along the axial direction, the upper end of which serves as a tray for supporting contents, the tray having a through hole formed therein, and a protrusion formed on the peripheral wall portion that protrudes radially outward and can be threaded onto the threaded portion of the outer tube through the slit of the inner tube, the movable body being housed within the middle plate portion slidably along the axial direction of the middle plate portion, the protrusion being protruding from the through hole of the middle plate portion and being embedded in the contents supported by the tray, and a flange portion formed radially outward from the lower end of the protrusion, A plurality of peripheral through holes are formed around the through hole of the tray, and a plurality of peripheral protrusions are formed around the protrusion on the upper surface of the flange portion of the movable body, capable of protruding from the peripheral through holes and being embedded in the contents supported by the tray. It is characterized by being a dispensing container. .

[0010] In addition, in the dispensing container, it is preferable that the peripheral through-hole and the peripheral protrusion have an arc-shaped shape in a plan view. [Effects of the Invention]

[0011] According to the dispensing container of the present invention, the amount of content that remains unused can be reduced. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0013] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a dispensing container according to an embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 is a partial front cross-sectional view showing a dispensing container 1 according to an embodiment of the present invention with the lid removed.

[0014] As shown in Figure 1, the dispensing container 1 of this embodiment comprises an outer tube 2, an inner tube 3 rotatably housed within the outer tube 2, a middle tray portion 4 housed within the inner tube 3 so as to be slidable along the axial direction, and a movable body 5 housed within the middle tray portion 4 so as to be slidable along the axial direction of the middle tray portion 4.

[0015] The outer tube 2 is formed by fitting a cylindrical thread-forming tube 22, housed within a bottomed, cylindrical outer tube main body 21 and having a threaded portion 221 formed on its inner circumferential surface, into the outer tube main body 21. A protrusion (not shown) is formed along the axial direction on the inner circumferential surface of the outer tube main body 21, and a long groove (not shown) is formed along the axial direction on the outer circumferential surface of the thread-forming tube 22. The engagement of the protrusion and the long groove positions the thread-forming tube 22 in the rotational direction within the outer tube main body 21. By forming the outer tube main body 21 and the thread-forming tube 22 separately, they can be formed using different materials. For example, if the outer tube main body 21 is made of metal for decorative purposes, forming a threaded portion on a metal member is difficult. Therefore, combining the outer tube main body 21 with a resin thread-forming tube 22 eliminates the need to form a threaded portion on the outer tube main body 21. A filling hole 23 is formed at the bottom of the outer tube 2. The contents C to be contained in the dispensing container 1 are filled in an unsolidified state through the filling hole 23 within the dispensing container 1 so as to extend into the inner tube 3, the central tray 4 and the movable body 5, and are then solidified within the dispensing container 1. In this way, a rod-shaped content C as shown in Figure 1 can be provided within the dispensing container 1. Although the filling hole 23 is formed in the present invention, it is not an essential component in the present invention, and the filling hole 23 may be eliminated, and the raw material for the contents C may be filled into the internal space from above the dispensing container 1 (above the plane of the page in Figure 1) to provide the contents C. Alternatively, the contents C may be provided by preparing a semi-solidified raw material and forcing it into the internal space from above the dispensing container 1 and solidifying it.

[0016] The inner tube 3 is a cylindrical member with a top that is housed in the outer tube 2 so as to be slidable along the axial direction. A slit 31 is formed in the inner tube 3 along the axial direction. Furthermore, a retaining protrusion 32 that protrudes radially outward is formed on the outer peripheral surface of the inner tube 3. When the inner tube 3 is inserted into the outer tube 2, a gap is formed between the upper end of the outer tube 2 and the inner tube 3, and an annular retaining member 7 is fitted into this gap. With this retaining member 7 fitted, the retaining protrusion 32 of the inner tube 3 is engaged with the retaining member 7, preventing the inner tube 3 from coming off the outer tube 2.

[0017] The inner dish 4 has a cylindrical shape with a top and is housed in the inner tube 3 so as to be slidable along the axial direction. The upper end of the inner dish 4 (the upper side of the paper in FIG. 1 ) serves as a tray 41 for supporting the contents. A circular through-hole 411 is formed in the center of the tray 41 in a plan view, and multiple peripheral through-holes 412, each having an arc-shaped shape in a plan view, are formed around the through-hole 411. The outer peripheral surface of the peripheral wall 42 of the inner dish 4 is provided with a columnar protrusion 43 that protrudes radially outward and can be threaded onto the threaded portion 221 of the outer tube 2 through the slit 31 of the inner tube 3. Furthermore, the inner peripheral surface of the peripheral wall 42 is formed with a stopper 44 that protrudes radially inward. The presence of this stopper 44 limits the downward movement of the movable body 5 housed in the inner dish 4.

[0018] The movable body 5 is accommodated within the middle dish 4 so as to be slidable along the axial direction of the middle dish 4. The movable body 5 has a protruding portion 51 that can protrude from the through-hole 411 of the middle dish 4 and is embedded in the contents C supported by the receiving tray 41, and a flange portion 52 formed radially outward from the lower end of the protruding portion 51.

[0019] The protruding portion 51 is cylindrical and hollow with a top, and has a peripheral wall formed with a communication hole 511. The formation of the communication hole 511 allows the interior and exterior of the central dish portion 4 to communicate through the communication hole 511, and as shown in Fig. 1, it is possible to provide the contents C so that they extend from the interior to the exterior of the central dish portion 4, preventing the contents C from falling out and making them easier to hold.

[0020] A plurality of peripheral protrusions 521 are formed on the upper surface of the flange 52 around the protrusion 51. The peripheral protrusions 521 are arc-shaped in plan view, can protrude from the peripheral through-holes 412, and are embedded in the contents C supported by the tray 41. Because the peripheral protrusions 521 are arc-shaped in plan view, the contact area with the contents C when embedded in the contents C can be made larger than when they are linear, making it easier to hold the contents C.

[0021] Fig. 2 is a plan view showing the inner tray 4 and movable body 5 combined together for use in the dispensing container 1 according to an embodiment of the present invention. As shown in Fig. 2, the movable body 5 is housed in the inner tray 4 with the protruding portion 51 protruding outward from the through-hole 411 and the peripheral protruding portion 521 protruding outward from the peripheral through-hole 412. This protruding portion 51 and the multiple (five in this embodiment) peripheral protruding portions 521 that surround it in a ring shape are embedded in the contents C as shown in Fig. 1, thereby preventing the contents C from falling out and making them easier to hold. Furthermore, embedding the peripheral protruding portions 521 in the contents C prevents the contents C from tilting during use.

[0022] It should be noted that a cylindrical cap with a top can be attached to the dispensing container 1 as shown by the two-dot chain line M in FIG. 1, but this cap is omitted in FIG.

[0023] Next, a description will be given of the operation of dispensing container 1 having the above-mentioned configuration. Figure 3 is a partial front cross-sectional view showing dispensing container 1 of Figure 1 in a state where inner tray 4 has been dispensed to the uppermost position.

[0024] By rotating the outer tube 2 while holding the inner tube 3 of the dispensing container 1, the user can advance or retract the inner plate 4 from or into the inner tube 3, as shown in Figure 3. Specifically, when the outer tube 2 is rotated, the protrusion 43 of the inner plate 4 that screws into the threaded portion 221 advances or retracts in the vertical direction, and as a result, the entire inner plate 4 moves up and down. This movement allows the inner plate 4, the movable body 5, and the contents C disposed between them to extend (or retract) from the state shown in Figure 1 to the state shown in Figure 3 (or conversely, from the state shown in Figure 3 to the state shown in Figure 1).

[0025] Fig. 4 is a partial front cross-sectional view showing a state in which the movable body 5 is exposed at the tip portion of the dispensing container 1 of Fig. 3 as the contents C decrease with use. As the contents C are consumed with use, the tip portion of the movable body 5 that was buried in the contents C becomes exposed to the outside as shown in Fig. 4. At this time, because the shape of the peripheral protrusion 521 in a plan view is arc-shaped, when the peripheral protrusion 521 is exposed outside the contents C as shown in Fig. 4, it is possible to prevent the peripheral protrusion 521 from catching on and damaging the place where the contents C is to be applied (for example, the user's lips if the contents C is lip balm, or the surface of paper if the contents C is glue).

[0026] Figure 5 is a partial front cross-sectional view showing a state in which the contents C have further decreased with use from the dispensing container 1 in the state shown in Figure 4, and the movable body 5 has been pushed in. If use continues from the state shown in Figure 4, the movable body 5 is pushed into the inner tray 4 as the contents C are consumed, as shown in Figure 5. This allows the contents C remaining on the tray 41 to be kept in a state where they can be applied at all times, and prevents the contents C on the tray 41 from being left in a state where they cannot be applied, thereby reducing the amount of contents C that remains unused.

[0027] FIG. 6 is a partial front cross-sectional view showing the state in which the contents C in the dispensing container 1 in the state shown in FIG. 5 have further decreased with use, with no contents C exposed outside the inner tray 4, and the movable body 5 has been completely pushed into the inner tray 4. If use continues from the state shown in FIG. 5, the contents C on the tray 41 will eventually be gone. At this time, a small amount of contents C remains below the protrusion 51 and flange 52 of the movable body 5 (below the page in FIG. 6 ). However, this is no longer visible from outside the dispensing container 1 because the protrusion 51 of the movable body 5 blocks the through-hole 411 in the inner tray 4. This improves the appearance of the dispensing container 1 after use. The movable body 5 pushed into the inner tray 4 is prevented from being pushed further downward than the state shown in FIG. 6 by the peripheral edge of the flange 52 abutting against the stopper 44.

[0028] Figure 7 is a partial front cross-sectional view showing a state in which only the movable body has been pushed into the inner tray from the dispensing container in the state shown in Figure 5. When only the movable body 5 is pushed in as shown in Figure 7 from the state shown in Figure 5, the contents C remaining on the tray 41 are no longer supported by the protruding portion 51 and the peripheral protruding portion 521, but because the amount of contents C remaining on the tray 41 is small, they do not fall off the tray 41 and can continue to be used.

[0029] In the dispensing container 1 according to the embodiment described above, the remaining amount of contents C that remains unused is a small amount that remains below the protruding portion 51 and flange portion 52 of the movable body 5, as shown in Figure 6. This makes it possible to reduce the amount of contents C that remains and becomes unusable when the dispensing container 1 is used up.

[0030] The present invention is not limited to the above-described embodiment, and various modifications can be adopted.

[0031] For example, in the dispensing container 1 according to the embodiment described above, the outer barrel main body 21 and the thread forming barrel 22 are formed as separate bodies, but this is not a limitation of the present invention. The outer barrel 2 may also be formed as a single unit. This reduces the number of parts and reduces manufacturing costs.

[0032] Furthermore, while the dispensing container 1 according to the embodiment described above is formed with five peripheral protrusions 521 that are arc-shaped in plan view, this is not limited to this and the number of peripheral protrusions 521 may be two to four, or six or more. Furthermore, the shape of peripheral protrusions 521 is not limited to being arc-shaped in plan view, and may be rectangular in plan view. In this case, the number and shape of peripheral through-holes 412 in inner tray 4 are also changed depending on peripheral protrusions 521. [Explanation of symbols]
