Description

[Technical Field]

[0001] The present invention relates to a dispenser used to apply stick glue, lip balm, lipstick, etc., and in particular to a dispenser that allows for thin and thick application. [Background technology]

[0002] There are several types of glues used to attach papers and other items, including starch glue, which is applied to the area to be glued with fingers or a spatula, or squeezed out from a tube and applied to the area to be glued; liquid glue (water glue), which is exuded from a sponge or silicone rubber attached to the tip of a bottle-shaped container and applied to the area to be glued; and stick glue, which is a solid stick-shaped glue that is dispensed from a dispenser-type container and applied to the area to be glued.However, when quick drying and a beautiful finished application are required, stick glue is considered to be preferable as it has little moisture content, dries easily, and is less likely to cause wrinkles or unevenness in the paper or other items to be glued.

[0003] However, conventional glue stick products have a specific diameter and application width, so a single glue stick cannot be used to quickly apply to a large area or to apply to small areas without spilling over. That is, when gluing narrow areas that are smaller than the diameter and application width of the glue stick product, there is a risk of the glue spilling out and staining the surrounding area, requiring the time and effort of placing unnecessary paper or the like under the gluing area to allow for the glue to spill out or wiping off the excess glue. The spilled glue is often wasted. Furthermore, when applying the peripheral edge of the tip of a dispensed solid glue stick to a small area, the shape of the peripheral edge can become distorted. When the dispensed solid glue is returned to the container, the solid glue spilling out from the edge of the tip of the container can adhere to the outer surface of the container, soiling the container or the cap that covers the opening. It can also adhere the cap to the container, requiring force to remove the cap the next time, making it difficult to attach or remove the cap. Furthermore, when glue sticks with small diameters and application widths are used to apply glue to large areas, it takes time and effort. Meanwhile, preparing multiple sizes for different purposes requires space for carrying and storing them in a pen case, etc.

[0004] Patent Document 1 discloses a glue container for switching between wide and narrow width applications, characterized in that a coating width switching member is provided on the front outer surface of a cylindrical compressible glue container body with a closed rear end face, so that the coating width switching member can slide in a straight line in the longitudinal direction of the body, and the sliding and locking of the switching member switches the positions of the tips of the wide coating nozzle and the narrow coating nozzle at the front end of the container body, making it possible to switch the glue coating width between wide and narrow by operating the switching member with one hand.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-47795 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the technology of Patent Document 1 is for liquid glue because it is applied using a nozzle, and is not suitable for stick-shaped solid glue.

[0007] Therefore, an object of the present invention is to provide a dispensing container that allows for both thin and thick application. [Means for solving the problem]

[0008] The dispensing container of the invention of claim 1 comprises an inner tube portion having an external thread portion extending in the axial direction on its outer peripheral side surface, an inner receiving tray portion disposed within the inner tube portion and having an internal thread portion on its inner peripheral side surface, a threaded rod portion disposed within the inner tube portion and having an external thread portion extending in the axial direction on its outer peripheral side surface and screwed with the inner receiving tray portion, an outer tube portion disposed around the outer periphery of the inner tube portion, and an outer tube portion disposed between the inner tube portion and the outer tube portion and having an internal thread portion on its inner peripheral side surface and screwed with the inner tube portion, It comprises an outer receiving tray portion engaged with the outer tube portion, a bottom portion integrated with the axial base end of the threaded rod portion, and a flange portion integrated with the axial base end of the inner tube portion and interposed between the outer tube portion and the bottom portion, and a first coated solid material having a small diameter is accommodated in the inner storage space formed by the inner tube portion, the inner receiving tray portion, and the threaded rod portion, and a second coated solid material having a large diameter is accommodated in the outer storage space formed by the inner tube portion, the outer tube portion, and the outer receiving tray portion.

[0009] The inner tube has a cylindrical or rectangular tube shape extending along the axis, and has a male thread on the outer peripheral surface (outer peripheral wall surface) of its side, i.e., has grooves or protrusions spirally formed along the axial direction. Note that the spiral grooves or protrusions are not limited to being continuous spirally along the axial direction, and may be discontinuous, as long as the outer tray portion threaded thereto can move relatively along the axial direction.

[0010] The inner tray has a hole in the center through which the threaded rod is inserted, and a female screw is threaded on the inner peripheral surface (inner peripheral wall surface) forming the hole, which is screwed onto the threaded rod by a male screw threaded on the outer peripheral wall surface of the threaded rod. When the first solid material is contained in the internal storage space formed by the inner cylinder, the inner tray, and the threaded rod, the inner tray supports one axial end face (base end face, rear end face) of the first solid material.

[0011] The threaded rod is generally axially shaped, with a male thread on the outer periphery of its side, i.e., with spiral grooves and protrusions along the axial direction, and is inserted into a hole in the inner tray, into which the inner tray is screwed. The base end (rear end) of the threaded rod is integral with the bottom.

[0012] The outer tube portion is disposed around the outer periphery of the inner tube portion at a predetermined distance from the inner tube portion and has a cylindrical or rectangular tubular shape extending along the axis. The outer tube portion has an engaging portion on its inner peripheral wall surface or the like that engages with the outer tray portion, and is engaged with the outer tray portion. The engagement can be achieved by linking the movements of the outer tube portion and the outer tray portion. For example, the inner peripheral side surface of the outer tube portion and the outer peripheral side surface of the outer tray portion can be provided with projections and recesses, and the engagement between them can be achieved by fitting them together.

[0013] The outer tray has a hole in the center through which the inner tube is inserted, and a female thread is threaded on the inner peripheral surface forming the hole, which threads into a male thread on the outer peripheral surface of the inner tube to screw into the inner tube. The outer tray also has an engaging portion on its outer peripheral side that engages with the inner peripheral surface of the outer tube, thereby engaging with the outer tube. When the second solid coating material is contained in the outer storage space formed between the inner and outer tubes, the outer tray supports one axial end face (base end face, rear end face) of the second solid coating material.

[0014] The bottom portion is provided integrally with the base end (rear end) in the axial direction of the threaded rod portion, and is rotatably connected to the flange portion. The flange is integrally formed on the axial base end of the inner cylindrical portion and is interposed between the outer cylindrical portion and the bottom portion.

[0015] The inner storage space is defined by an inner tube portion, an inner tray portion, and a threaded rod portion, and is filled with and accommodates a first coated solid material that is smaller in diameter (narrower, thinner) than the second coated solid material. Examples of the first solid to be applied include a stick-shaped solid glue, lip balm, lipstick, and the like.

[0016] The outer storage space is defined by an inner tube portion, an outer tray portion, and an outer tube portion, and is filled with and accommodates a second coated solid material that is larger in diameter (narrower, thicker) than the first coated solid material. Examples of the second solid substance to be applied include a stem-shaped solid glue, lip balm, lipstick, etc., and the second solid substance to be applied may be the same as or different from the first solid substance to be applied.

[0017] The inner tube portion of the dispensing container of the invention of claim 2 has a protrusion- or groove-shaped guide portion extending in the axial direction on its inner peripheral side surface, and the inner receiving tray portion has a groove- or protrusion-shaped fitting portion on its outer peripheral side surface that fits into the guide portion. [Effects of the Invention]

[0018] According to the dispensing container of the invention of claim 1, an inner cylindrical part has an axially extending male thread on its outer peripheral side surface, and a threaded rod part has an axially extending male thread on its outer peripheral side surface, and an inner receptacle part has an inner peripheral side surface and is screwed onto the threaded rod part, disposed within the inner cylindrical part, thereby forming an inner storage space for storing a small-diameter first solid coating material between the inner cylindrical part, the inner receptacle part, and the threaded rod part. Also, an outer cylindrical part is disposed around the outer periphery of the inner cylindrical part, and an outer receptacle part has an inner peripheral side surface and is screwed onto the inner cylindrical part, and is disposed between the outer cylindrical part and the inner cylindrical part, thereby forming an outer storage space for storing a large-diameter second solid coating material between the outer cylindrical part, the outer receptacle part, and the inner cylindrical part. A bottom portion is integrated with the axial base end of the threaded rod portion, and a flange portion is integrated with the axial base end of the inner tube portion, with the flange portion being interposed between the bottom portion and the outer tube portion.

[0019] Therefore, when the bottom is rotated, the threaded rod portion integrated with the bottom rotates, and the inner tray portion threaded onto the threaded rod portion moves on the threaded rod portion along the axial direction of the threaded rod portion, so that the small-diameter first solid material contained in the inner storage space formed among the inner tube portion, the inner tray portion, and the threaded rod portion can be freely dispensed from the inner tube portion. Furthermore, when the outer tube is rotated, the outer tray, which is engaged with the outer tube and threadedly engaged with the inner tube, rotates and moves on the inner tube along the axial direction of the inner tube, thereby allowing the large-diameter second solid coating material contained in the outer accommodating space formed between the inner tube, the outer tray, and the outer tube to be freely dispensed from between the outer tube and the inner tube. Thus, the rotation of the bottom allows the small-diameter first solid to protrude from the inner cylinder, while the rotation of the outer cylinder allows the large-diameter second solid to protrude from the outer cylinder.

[0020] Therefore, by rotating only the bottom portion and moving the inner tray toward the axial tip of the threaded rod, only the small-diameter first solid object can be dispensed from the inner tube, and coating can be performed using the coating surface at the small-diameter tip of the first solid object. Alternatively, by rotating only the outer tube portion and moving the outer tray toward the axial tip of the inner tube, only the large-diameter second solid object can be dispensed from the inner and outer tubes, and coating can be performed using the coating surface at the large-diameter tip of the second solid object. Alternatively, by rotating the bottom portion and the outer tube, the small-diameter first solid object and the large-diameter second solid object can be dispensed from the inner and outer tubes, and coating can be performed by aligning the coating surface at the small-diameter tip of the first solid object and the coating surface at the large-diameter tip of the second solid object. Thus, the coating surface can be switched between a wide and a narrow coating surface, changing the shape and area of ​​the coating surface. In other words, both thin and thick coatings are possible. Furthermore, different types of solid materials can be accommodated in a small-diameter first solid material and a large-diameter second solid material, and different types of solid materials can be applied separately or simultaneously.

[0021] According to the dispensing container of claim 2, the inner tube has a protrusion- or groove-shaped guide portion extending in the axial direction on its inner peripheral surface, and the inner tray has a fitting portion on its outer peripheral surface that fits into the guide portion. The fitting portion of the inner tray fits into the guide portion of the inner tube, so that the inner tray, which is threaded onto the threaded rod, moves along the axial direction of the threaded rod while being guided by the guide portion of the inner tube. Therefore, rotation of the bottom and the threaded rod does not cause the inner tray, which is threaded onto them, to rotate itself, i.e., it can reliably move along the axial direction of the threaded rod without spinning. This provides the effect of claim 1 and is therefore easy to use. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the embodiments, the same symbols and the same reference numerals mean the same or corresponding functional parts in the embodiments, and therefore, redundant detailed explanations will be omitted here.

[0024] [Embodiment Mode] A dispensing container according to an embodiment of the present invention will be described with reference to Figures 1 to 6. The embodiment of the present invention shows an example in which the dispensing container of the present invention is applied to a glue stick container.

[0025] As shown in Figure 1, the glue stick container 1 as a dispensing container in this embodiment comprises a container body 2 made of resin (e.g., hard resin such as polypropylene) or the like and having an approximately cylindrical shape overall, and a cap 3 having a short cylindrical shape with a top made of resin (e.g., hard resin such as polypropylene) or the like and removably fitted (covered) into the opening at the tip of the container body 2, allowing the opening to be opened and closed.

[0026] As shown in Figures 1 to 6, the container body 2 comprises a cylindrical inner tube portion 11, an inner tray portion 12 arranged inside the inner tube portion 11, a threaded rod portion 13 arranged inside the inner tube portion 11 and penetrating the inner tray portion 12, a cylindrical outer tube portion 21 arranged around the outer periphery of the inner tube portion 11, an outer tray portion 22 arranged between the inner tube portion 11 and the outer tube portion 21, a bottom portion 31 integrated with one end of the threaded rod portion 13 in the axial direction, and a flange portion 41 integrated with one end of the inner tube portion 11 in the axial direction O and interposed between the outer tube portion 21 and the bottom portion 31. An inner storage space 10 in which the first solid glue S is stored is formed between the inner tube portion 11, the inner tray portion 12, and the threaded rod portion 13, and an outer storage space 20 in which the second solid glue L is stored is formed between the inner tube portion 11, the outer tube portion 21, and the outer tray portion 22.

[0027] The inner tube portion 11 is generally cylindrical, and has a male screw thread on its outer peripheral side surface (the radially outer surface, the outer peripheral wall surface), with a male thread portion 115 having a spirally formed screw groove / thread on the outer peripheral side surface. Furthermore, the inner peripheral side surface (the radially inner surface, the inner peripheral wall surface) of the inner tube portion 11 has a plurality of protrusions 116 extending in the direction of the axis O formed at predetermined intervals in the circumferential direction (in FIG. 3, four are formed at equal intervals in the circumferential direction). The protrusions 116 are rib-shaped and extend in the direction of the axis O, and fit into vertical grooves 126 formed on the outer peripheral side surface of the inner receptacle portion 12 (described later), guiding movement of the inner receptacle portion 12 in the direction of the axis O relative to the threaded rod portion 13. Furthermore, at the base end side, which is one end side in the axial direction O, of the inner tube portion 11, a flange-shaped annular protrusion 117 extending radially outward is formed on the outer peripheral side surface, and the annular protrusion 117 is fitted into an annular recess 217 formed on the inner peripheral side surface at the base end side, which is one end side in the axial direction O, of the outer tube portion 21 described later.

[0028] The inner saucer portion 12 is composed of a short cylindrical saucer portion 12a with a bottom and a short cylindrical insertion portion 12b with a hole formed in the center. A female screw is threaded on the inner peripheral side of the insertion portion 12b, and the inner peripheral side has a female screw portion 125 with a spirally formed screw groove and thread. In addition, on the outer peripheral side of the inner saucer portion 12, multiple vertical grooves 126 extending in the vertical direction (direction of the axis O) are formed at predetermined intervals in the circumferential direction (in Figure 3, four are formed at equal intervals in the circumferential direction) corresponding to the protrusions 116 formed on the inner peripheral side of the inner cylindrical portion 11. The outer shape of the cross section of the inner saucer portion 12 is approximately circular.

[0029] The inner receiving tray portion 12 engages with the inner tube portion 11 by fitting a vertical groove portion 126 formed on its outer peripheral side surface with a protrusion portion 116 formed on the inner peripheral side surface of the inner tube portion 11, and the threaded rod portion 13 is passed through a hole in the insertion portion 12b, and is threadedly engaged with the threaded rod portion 13 so as to be freely movable in the direction of its axis O by threading a female threaded portion 125 formed on the inner peripheral side surface of the insertion portion 12b with a male threaded portion 135 formed on the outer peripheral side surface of the threaded rod portion 13 described below.

[0030] The threaded rod portion 13 is axially shaped, more specifically, rod-shaped with a generally circular cross-sectional outline, and has a male screw threaded on its outer peripheral surface, with a male thread portion 135 having spiral grooves and threads formed on the outer peripheral surface. A flange-shaped annular protrusion 137 is provided at the base end of the threaded rod portion 13 in the direction of the axis O. This flange-shaped annular protrusion 137 is provided so as to protrude radially outward from the outer peripheral surface of the threaded rod portion 13. Furthermore, a bottom portion 31, which will be described later, is integrally provided at the base end side of the threaded rod portion 13 in the direction of the axis O. As will be described later, the flange-shaped annular protrusion 137 of the threaded rod portion 13 fits into an annular recess 47 formed in an annular shape along the inner peripheral side surface of a short cylindrical flange 41 integrated with the base end side of the inner cylindrical portion 11 in the axial direction O, so that the bottom portion 31 integrated with the base end side of the threaded rod portion 13 in the axial direction O is rotatably attached and fixed to the flange 41 integrated with the base end side of the inner cylindrical portion 11 in the axial direction O. The threaded rod portion 13 inserted into the central hole of the inner receptacle portion 12 inside the inner cylindrical portion 11 is located on the axial line O of the outer cylindrical portion 21 and the inner cylindrical portion 11, and protrudes toward the interior of the inner cylindrical portion 11 on the axial line O of the flange 41.

[0031] The inner receptacle portion 12 and the threaded rod portion 13 are attached to the threaded rod portion 13 by the threaded rod portion 13 being passed through a hole in the insertion portion 12b of the inner receptacle portion 12, and by threaded engagement (meshing) between the female threaded portion 125 formed on the inner side surface of the insertion portion 12b of the inner receptacle portion 12 and the male threaded portion 135 formed on the outer side surface of the threaded rod portion 13. In addition, the inner tube portion 11 and the inner saucer portion 12 are engaged by the engagement of a protrusion portion 116 protruding from the inner peripheral side surface of the inner tube portion 11 with a vertical groove portion 126 grooved in the outer peripheral side surface of the inner saucer portion 12. The shapes of the protrusions 116 and the vertical grooves 126 are not particularly limited, and for example, the protrusions 116 may be shaped to protrude from the inner peripheral surface of the inner cylindrical portion 11 toward the radial center of the inner cylindrical portion 11 and narrow (become thinner) toward the tip, and the corresponding vertical grooves 126 may also be shaped to narrow toward the bottom. The protrusions 116 have a protruding length of, for example, about 0.4 to 2 mm and a width of, for example, about 0.4 mm to 3 mm, and the vertical grooves 126 have a depth of, for example, about 0.5 to 2.5 mm and a width of, for example, about 0.5 mm to 3.5 mm.

[0032] The tip of the threaded rod portion 13 may be provided with a small diameter protrusion 13a, or may be tapered or pointed with a diameter decreasing toward the tip surface, or may have a recess with a divided tip surface. This increases the engagement force with the small diameter shaft-shaped first solid glue S housed in the inner housing space 10, and allows the first solid glue S to be stably supported even when a long amount of the first solid glue S is dispensed from the container body 2.

[0033] The outer cylinder 21 is cylindrical and has a larger diameter than the inner cylinder 11, and is disposed around the outer periphery of the inner cylinder 11 at a predetermined distance from the inner cylinder 11 so as to surround the side periphery of the inner cylinder 11. On its inner peripheral surface, a plurality of protrusions 216 extending in the direction of the axis O are formed at predetermined intervals in the circumferential direction (in FIG. 3, four protrusions are formed at equal intervals in the circumferential direction). The protrusions 216 are rib-shaped and extend in the direction of the axis O of the outer cylinder 21, and fit into vertical grooves 226 formed on the outer peripheral surface of the outer receiving tray 22, which will be described later. In addition, an annular recess 217 is formed on the inner peripheral side surface of the base end side, which is one end side of the outer tube portion 21 in the axial direction O, and the annular recess 217 is fitted into a flange-shaped annular protrusion 117 formed on the outer peripheral side surface of the base end side, which is one end side of the inner tube portion 11 in the axial direction O.

[0034] The tip of the outer tube portion 21 is thinner and has a smaller diameter than the base end, and a stepped surface corresponding to the thickness of the side surface of the cap 3 is formed, allowing the cap 3 to be fitted (externally fitted) flush with the outer tube portion 21. Furthermore, the tip of the outer tube portion 21 may be provided with a rib 2a protruding radially outward from the outer peripheral surface along the circumferential direction. As a result, when the cap 3 is fitted externally to the container body 2, the rib 2a comes into close contact with the inner peripheral surface of the cap 3, resulting in a tight fit, improving the airtightness and further preventing the solid glues S and L from drying out. Furthermore, by providing a rib (not shown) protruding radially inward along the circumferential direction on the cap 3, the rib will come into close contact with the outer peripheral surface of the outer tube portion 21 when the cap 3 is fitted externally to the container body 2, resulting in a tight fit, improving the airtightness and further preventing the solid glues S and L from drying out. Furthermore, when carrying out the present invention, vertical grooves or vertical protrusions extending in the direction of the axis O may be formed at predetermined intervals along the circumferential direction on the outer peripheral side surface of the outer cylindrical portion 21 by knurling or the like. This makes it easier to grip the outer peripheral side surface of the outer cylindrical portion 21, making it easier to rotate the outer cylindrical portion 21 and improving operability. It also makes it less likely to roll.

[0035] The outer saucer portion 22 comprises a bottomed, short-cylindrical saucer portion 22a and a short-cylindrical insertion portion 22b having a hole formed in its center. An internal thread is threaded on the inner peripheral surface of the insertion portion 22b, and the inner peripheral surface has an internal thread portion 225 with a spirally formed screw groove and threads. Furthermore, on the outer peripheral surface of the outer saucer portion 22, a plurality of vertical grooves 226 extending in the direction of the axis O are formed at predetermined intervals in the circumferential direction (four are formed at equal intervals in the circumferential direction in FIG. 3 ) corresponding to the protrusions 216 formed on the inner peripheral surface of the outer tube portion 21, and fit with the protrusions 216 of the outer tube portion 21. The outer saucer portion 22 has a circular cross-sectional outer shape, and its outer diameter is larger than that of the inner saucer portion 12.

[0036] The outer tube portion 21 and the outer receiving tray portion 22 are engaged by fitting a protrusion portion 216 formed on the inner side surface of the outer tube portion 21 with a vertical groove portion 226 formed on the outer side surface of the outer receiving tray portion 22. In addition, the inner tube portion 11 of the outer receiving tray portion 22 is passed through the hole of the insertion portion 22b, and is attached to the inner tube portion 11 by screwing together the female thread portion 225 formed on the inner side surface of the outer receiving tray portion 22 and the male thread portion 115 formed on the outer side surface of the inner tube portion 11. In other words, the outer receiving tray portion 22 engages with the outer tube portion 21 by fitting the vertical groove portion 226 formed on its outer peripheral side surface with the protrusion portion 216 formed on the inner peripheral side surface of the outer tube portion 21, and is also screwed onto the inner tube portion 11 so as to be freely movable in the direction of its axis O by threading the female screw portion 225 formed on the inner peripheral side surface with the male screw portion 115 formed on the outer peripheral side surface of the inner tube portion 11. The shapes of the protrusions 216 and the vertical grooves 226 are not particularly limited, and for example, the protrusions 216 may be shaped to protrude from the inner peripheral surface of the outer cylindrical portion 21 toward the radial center of the outer cylindrical portion 21 and narrow (become thinner) toward the tip, and the corresponding vertical grooves 226 may also be shaped to narrow toward the bottom. The protrusions 216 have, for example, a protrusion length of about 0.4 to 2 mm and a width of about 0.4 mm to 3 mm, and the vertical grooves 226 have, for example, a depth of about 0.5 to 2.5 mm and a width of about 0.5 mm to 3.5 mm.

[0037] The outer tube portion 21 and the inner tube portion 11 can rotate freely relative to each other without any rattle because the annular recess 217 formed on the base end side, which is one end side of the outer tube portion 21 in the axial direction O, is fitted with the annular protrusion 117 formed on the base end side, which is one end side of the inner tube portion 11 in the axial direction O.

[0038] Furthermore, a flange portion 41 is provided on one end side of the outer cylindrical portion 21 and the inner cylindrical portion 11 in the axis O direction. The flange 41 is formed integrally with the base end, which is one end of the inner cylindrical portion 11 in the axial direction O, and is interposed between the outer cylindrical portion 21 and the bottom portion 31. It is a short cylinder having a through-hole in the center with a diameter substantially equal to the inner diameter of the inner cylindrical portion 11. The flange 41 is formed to protrude radially outward from the base end side of the inner cylindrical portion 11 in the axial direction O, and its outer diameter is substantially equal to the outer diameter of the outer cylindrical portion 21. The flange 41 has an annular recess 47 formed on its inner circumferential surface, into which a flange-shaped annular protrusion 137 formed to protrude radially outward from the base end of the threaded rod portion 13 in the axial direction O is fitted. In addition, the base end terminal of the male threaded portion 135 of the threaded rod portion 13 is positioned a predetermined distance away from the annular protrusion 137, and the movement of the inner receiving portion 12 screwed onto the threaded rod portion 13 is stopped at a position a predetermined distance away from the annular protrusion 137, i.e., at a position where it does not touch the annular protrusion 137.

[0039] Furthermore, in the container body 2, a bottom portion 31 is provided on the opposite side of the flange portion 41 to the outer cylindrical portion 21 and inner cylindrical portion 11 side. The bottom portion 31 has a generally circular cross-sectional outer shape and a short cylindrical shape with a top, and its outer diameter is generally the same as that of the outer tube portion 21. It is formed integrally with the base end portion, which is one end portion in the axial direction of the threaded rod portion 13. Vertical grooves 31a extending vertically (in the axial direction of the axis O) are formed at predetermined intervals along the circumferential direction on the outer peripheral side surface of the bottom portion 31 by knurling or the like. This makes the outer peripheral side surface of the bottom portion 31 uneven, making it easier to pinch and grip the outer peripheral side surface of the bottom portion 31 with your fingers, making it easier to rotate the bottom portion 31 and improving operability.

[0040] The bottom portion 31 and the flange portion 41 are rotatably fixed to each other by fitting a flange-shaped annular protrusion 137 of the threaded rod portion 13, which is integrated with the bottom portion 31, into an annular recess 47 of the flange portion 41. That is, the flange-shaped annular protrusion 137 provided at the base end portion in the axial direction of the threaded rod portion 13, which is integrated with the bottom portion 31, is fitted into the annular recess 47 recessed in the inner peripheral surface of the flange portion 41, so that the bottom portion 31 and the flange portion 41 are connected to each other in a relatively anti-disconnecting state and rotatable.

[0041] In the container body 2, the outer cylinder 21, the inner cylinder 11, the flange 41, and the bottom 31 are connected and fixed so as to be rotatable relative to one another. In this embodiment, the cylinders of the inner cylinder 11 and the outer cylinder 21, the flange 41, and the bottom 31 are provided close to one another. The cap 3, the outer cylinder 21, the flange 41, and the bottom 31 all have circular cross-sectional shapes of approximately the same size and are formed in a cylindrical shape, and the outer peripheral surface of the container body 2 is flush.

[0042] In the glue stick container 1 having such a configuration, the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13 form an inner storage space 10 for storing a first axial solid glue S, and the outer tube portion 21, the outer receiving tray portion 22, and the inner tube portion 11 form an outer storage space 20 for storing another axial second solid glue L. Therefore, the shaft-shaped first solid glue S is accommodated in the inner storage space 10 defined by the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13, and the shaft-shaped second solid glue L is accommodated in the outer storage space 20 defined by the outer tube portion 21, the outer receiving tray portion 22, and the inner tube portion 11.

[0043] That is, the inner storage space 10 formed by the inner surface of the inner tube portion 11, the recess of the inner receiving tray portion 12, and the outer surface of the threaded rod portion 13, and the outer storage space 20 formed by the outer surface of the inner tube portion 11, the inner surface of the outer tube portion 21, and the recess of the outer receiving tray portion 22 are separated by the inner tube portion 11, and the inner storage space 10 formed by the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13 and the outer storage space 20 formed by the inner tube portion 11, the outer tube portion 21, and the outer receiving tray portion 22 separately store solid glues S and L.

[0044] The first solid glue S is accommodated in the inner storage space 10 and the second solid glue L is accommodated in the outer storage space 20 by, for example, preparing a cylindrical mold (not shown) that corresponds to the inner cylindrical portion 11, pouring a viscous liquid-like glue from above the cylindrical mold to fill the inner cylindrical portion 11, allowing it to cool and solidify, and then removing it from the mold. In addition, the second solid glue L is accommodated in the outer accommodation space 20 by, for example, preparing a cylindrical mold (not shown) that corresponds to the space between the outer tube portion 21 and the inner tube portion 11, pouring a viscous liquid glue from above the cylindrical mold to fill the space between the inner tube portion 11 and the outer tube portion 21, allowing it to cool and solidify, and then removing it from the mold.

[0045] At this time, the small-diameter shaft-shaped first solid glue S accommodated in the inner storage space 10 formed by the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13 has one axial end supported by the inner receiving tray portion 12, and the large-diameter shaft-shaped second solid glue L accommodated in the outer storage space 20 formed by the inner tube portion 11, the outer tube portion 21, and the outer receiving tray portion 22 has one axial end supported by the outer receiving tray portion 22. The threaded rod portion 13 is located at the axial center of the first solid glue S contained in the inner storage space 10. Furthermore, the inner tube portion 11, the first solid glue S, and the threaded rod portion 13 are located in this order from the outside to the inside in the radial direction of the tube for the second solid glue L contained in the outer storage space 20. That is, the threaded rod portion 13 is located on the inner peripheral side surface of the first solid glue S, and the inner tube portion 11 is located on the inner peripheral side surface of the second solid glue L.

[0046] Thus, the glue stick container 1 of this embodiment has a two-layer structure in which the first solid glue S is contained in the small-diameter inner storage space 10 formed by the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13, and the second solid glue L is contained in the large-diameter outer storage space 20 formed by the inner tube portion 11, the outer tube portion 21, and the outer receiving tray portion 22 and arranged around the outside of the first solid glue S, separated by the inner tube portion 11.The inner storage space 10 formed by the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13 and the outer storage space 20 formed by the inner tube portion 11, the outer tube portion 21, and the outer receiving tray portion 22 can store solid glues S and L of different diameters (thinness, thickness), and it is also possible to store solid glues S and L of different types (ingredients, formulations, etc.), i.e., different types. The solid adhesives S and L may contain a coloring agent that becomes transparent when dried, so that the applied area can be easily identified by the color of the coloring agent immediately after application.

[0047] In other words, in the glue stick container 1 of this embodiment, the inner tube portion 11 is arranged inside the outer tube portion 21, and since the inner tube portion 11 has a smaller diameter than the outer tube portion 21, the first solid glue S, which is approximately columnar (approximately cylindrical) and filled into the inner storage space 10 formed by the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13 and solidified within the inner storage space 10, has a smaller diameter (thinner) than the second solid glue L, which is approximately columnar (approximately cylindrical) and filled into the outer storage space 20 formed by the inner tube portion 11, the outer tube portion 21, and the outer receiving tray portion 22 and solidified within the outer storage space 20. In other words, the outer tube portion 21 is arranged around the outer periphery of the inner tube portion 11, and since the outer tube portion 21 has a larger diameter than the inner tube portion 11, the second solid glue L filled into the outer storage space 20 formed by the inner tube portion 11, the outer tube portion 21, and the outer receiving tray portion 22 and solidified within the outer storage space 20 has a larger diameter (thicker) than the first solid glue S filled into the inner storage space 10 formed by the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13 and solidified within the inner storage space 10.

[0048] Therefore, according to the glue stick container 1 of this embodiment, solid glues S, L of different diameters (thinness, thickness) can be stored, and as will be described later, solid glues S, L of different diameters (thinness, thickness) can be dispensed and used separately or together. Also, by having two storage spaces for the solid glues S, L, the inner storage space 10 and the outer storage space 20 formed around the outer periphery of the inner storage space 10 via the inner cylinder portion 11, it is possible to store different types of solid glues S, L separately, and therefore different types of solid glues S, L can be dispensed and used separately or together.

[0049] As described above, in the glue stick container 1 of this embodiment, a threaded rod 13 and an inner receptacle 12 screwed onto the threaded rod 13 are provided within the inner tube 11, and a bottom 31 is integrated with the base end of the threaded rod 13 in the direction of axis O. An outer tube 21 is provided around the outer periphery of the inner tube 11, and an outer receptacle 22 provided between the outer tube 21 and the inner tube 11 screw-engages with and engages with the outer tube 21. Furthermore, a flange 41 is integrated with one end of the inner tube 11 in the direction of axis O, and the flange 41 is interposed between the outer tube 21 and the bottom 31.

[0050] Therefore, when the bottom portion 31 is rotated, the threaded rod portion 13 integral with it rotates, and this rotation causes the inner receptacle portion 12, which is threadedly engaged with the threaded rod portion 13, to move on the threaded rod portion 13 along its axis O. In other words, when the bottom portion 31 is rotated in a specific direction, the threaded rod portion 13 rotates in the same direction, and this rotation causes the inner receptacle portion 12 to move on the threaded rod portion 13 in one direction along its axis O. Furthermore, when the bottom portion 31 is rotated in the reverse direction, the threaded rod portion 13 also rotates in the reverse direction, and this rotation causes the inner receptacle portion 12 to move on the threaded rod portion 13 in the opposite direction along its axis O.

[0051] Furthermore, when the outer tube portion 21 is rotated, the protrusions 216 formed on the inner peripheral side surface of the outer tube portion 21 engage with the vertical grooves 226 formed on the outer peripheral side surface of the outer tray portion 22, causing the outer tray portion 22 to rotate, and because the outer tray portion 22 is threadedly engaged with the inner tube portion 11, the outer tray portion 22 moves on the inner tube portion 11 in the direction of its axis O. In other words, when the outer tube portion 21 is rotated in a specific direction, the outer tray portion 22 rotates in the same direction, and this rotation causes the outer tray portion 22 to move in one direction along the axis O on the inner tube portion 11. Furthermore, when the outer tube portion 21 is rotated in the reverse direction, the outer tray portion 22 also rotates in the reverse direction, causing the outer tray portion 22 to move on the inner tube portion 11 in the opposite direction along the axis O.

[0052] Therefore, the small-diameter shaft-shaped first solid glue S contained in the inner storage space 10 defined by the inner cylinder 11, the inner tray 12, and the threaded rod 13 has its bottom supported by the inner tray 12, which is screwed onto the threaded rod 13. When the threaded rod 13 rotates due to the rotation of the bottom 31 integrated with the base end of the threaded rod 13 in the axial O direction, the inner tray 12 screwed onto the threaded rod 13 moves in the axial O direction relative to the threaded rod 13, and accordingly, the first solid glue S supported by the inner tray 12 moves (rises and falls) in the axial O direction. Therefore, the rotation of the bottom 31 allows the first solid glue S contained in the inner storage space 10 to be freely dispensed from the container body 2.

[0053] In addition, the large-diameter shaft-shaped second solid glue L accommodated in the outer storage space 20 defined by the inner tube 11, the outer tube 21, and the outer tray 22 has its bottom supported by the outer tray 22, and since the outer tray 22 is engaged with the outer tube 21, when the outer tray 22 rotates due to the rotation of the outer tube 21, the outer tray 22, which is screwed onto the inner tube 11, moves in the direction of the axis O relative to the inner tube 11, and accordingly, the second solid glue L supported by the outer tray 22 moves (rises and falls) in the direction of the axis O. Therefore, when the outer tube 21 rotates, the second solid glue L accommodated in the outer storage space 20 can be freely dispensed from the container body 2.

[0054] That is, when the bottom portion 31 is rotated in a specific direction, the threaded rod portion 13 formed integrally with the bottom portion 31 rotates inside the inner tube portion 11, and the inner receptacle portion 12 screwed onto the threaded rod portion 13 is guided by the protrusions 116 on the inner peripheral surface of the inner tube portion 11 in the grooves 126 on its outer peripheral surface, and moves along the axis O of the threaded rod portion 13 toward the tip of the inner tube portion 11. As a result, the small-diameter first solid glue S contained in the inner storage space 10 defined by the inner tube portion 11, the inner receptacle portion 12, and the threaded rod portion 13, and one axial end of which is supported by the inner receptacle portion 12, is pushed out from the opening at the tip of the inner tube portion 11. Therefore, the first solid glue S can be protruded from the tip of the inner tube portion 11 and used for application. Furthermore, when the bottom portion 31 is rotated in the opposite direction, the threaded rod portion 13 formed integrally with the bottom portion 31 rotates in the opposite direction inside the inner tube portion 11, and the inner receiving tray portion 12 screwed onto the threaded rod portion 13 is guided by the protrusion portion 116 on the inner peripheral surface of the inner tube portion 11 in the groove portion 126 on the outer peripheral surface of the inner receiving tray portion 12, and moves along the axis O of the threaded rod portion 13 toward the base end side of the inner tube portion 11. This allows the small-diameter first solid glue S to be retracted into the inner tube portion 11.

[0055] On the other hand, when the outer tube portion 21 is rotated in a specific direction, the outer tray portion 22, which is disposed between the outer tube portion 21 and the inner tube portion 11 and is screwed onto the inner tube portion 11 while also engaging with the outer tube portion 21, rotates, causing the outer tray portion 22, which is screwed onto the inner tube portion 11, to move toward the tip of the outer tube portion 21 along the axial line O of the inner tube portion 11. As a result, the large-diameter second solid glue L, which is accommodated in the outer accommodation space 20 defined by the inner tube portion 11, the outer tray portion 22, and the outer tube portion 21 and has one end in the axial direction supported by the outer tray portion 22, is pushed out from the opening at the tip between the inner tube portion 11 and the outer tube portion 21. Therefore, the second solid glue L can be protruded from the tip between the inner tube portion 11 and the outer tube portion 21 and used for application. Furthermore, when the outer tube portion 21 is rotated in the opposite direction, the outer receiving tray portion 22, which is disposed between the outer tube portion 21 and the inner tube portion 11 and is screwed onto the inner tube portion 11 while being engaged with the outer tube portion 21, rotates, and the outer receiving tray portion 22, which is screwed onto the inner tube portion 11, moves along the axis O of the inner tube portion 11 toward the base end side of the outer tube portion 21. As a result, the second solid glue L, which has a larger diameter, can be retracted inside between the inner tube portion 11 and the outer tube portion 21.

[0056] In this way, in the glue stick container 1 of this embodiment, the inner tube portion 11, the inner receptacle portion 12, and the threaded rod portion 13 form the inner storage space 10 for storing the small-diameter first solid glue S, and the inner tube portion 11, the outer tube portion 21, and the outer receptacle portion 22 form the outer storage space 20 for storing the large-diameter second solid glue L. When the bottom portion 31 rotates, the threaded rod portion 13 integrated with the bottom portion 31 also rotates, and the inner Since the tray portion 12 moves on the threaded rod portion 13 in the direction of its axis O, the small-diameter first solid glue S supported by the inner tray portion 12 is movable in the direction of the axis O, and further, as the outer tube portion 21 rotates, the outer tray portion 22 engaged with the outer tube portion 21 rotates, and the outer tray portion 22 screwed onto the inner tube portion 11 moves on the inner tube portion 11 in the direction of its axis O, and therefore the large-diameter second solid glue L supported by the outer tray portion 22 is movable in the direction of the axis O. Therefore, the small-diameter first solid glue S can be dispensed (protruded and retracted) from the container body 2 by rotating the bottom portion 31, and the large-diameter second solid glue L can be dispensed from the container body 2 by rotating the outer tube portion 21, so that the small-diameter first solid glue S and the large-diameter second solid glue L can be dispensed separately from the container body 2.

[0057] In other words, in the glue stick container 1 of this embodiment, when the bottom 31 is rotated, the threaded rod portion 13 inside the inner tube portion 11 rotates, allowing the inner receiving tray portion 12 that is screwed onto the threaded rod portion 13 to move freely along the outer surface of the threaded rod portion 13 in the direction of its axis O, and when the outer tube portion 21 is rotated, the outer receiving tray portion 22 that is arranged between the outer tube portion 21 and the inner tube portion 11 and engages with the outer tube portion 21 and is screwed onto the inner tube portion 11 rotates, allowing the outer receiving tray portion 22 to move freely along the outer surface of the inner tube portion 11 in the direction of its axis O, but the inner receiving tray portion 12 and the outer receiving tray portion 22 can each move up and down independently. Between the inner saucer portion 12 and the inner tube portion 11, a vertical protrusion portion 116 formed on the inner peripheral side surface of the inner tube portion 11 is fitted with a vertical groove portion 126 formed on the outer peripheral side surface of the inner saucer portion 12, so that when the bottom portion 31 is rotated, even if the threaded rod portion 13 rotates due to the rotation of the bottom portion 31, the inner saucer portion 12 itself threaded onto the threaded rod portion 13 does not rotate, and the movement of the threaded rod portion 13 in the direction of the axis O is guided by the protrusion portion 116 of the inner tube portion 11. Therefore, even if the bottom portion 31 is rotated, the inner saucer portion 12 and the inner tube portion 11 do not rotate, and therefore the outer saucer portion 22 threaded onto the outer peripheral side of the inner tube portion 11 does not rotate. Furthermore, even when the outer tube portion 21 is rotated, even if the outer receiving tray portion 22 engaged with the outer tube portion 21 rotates, the inner tube portion 11 to which the outer receiving tray portion 22 is screwed does not rotate, and naturally the inner receiving tray portion 12 inside the inner tube portion 11 does not rotate either. Therefore, the first solid glue S stored in the inner storage section 10 and the second solid glue stored in the outer storage section 20 can be freely dispensed from the tip ends of the inner tube section 11 and the outer tube section 21 independently of each other without being linked together.

[0058] Therefore, when applying glue to narrow or small areas, as shown in Figures 5(a) and 6(a), by rotating only the bottom 31, only the small-diameter (thin) first solid glue S can be dispensed from the container body 2, and only the small-diameter first solid glue S can be applied.This makes it possible to apply glue to narrow or small areas, such as right-angled corners or near straight edges, without the glue spilling out, and also makes it possible to apply glue without waste or unevenness, thereby reducing the effort and time required for applying glue. That is, when applying a thick solid glue like the second solid glue L to narrow or small areas, it can easily overflow from the area to be applied, or the edge of the top surface must be rubbed against the surface multiple times, resulting in overlapping glue on the surface and uneven application and waste, making the glue application process time-consuming and labor-intensive. By contrast, the use of the small-diameter first solid glue S makes it possible to apply glue without overflow, reduces the need to repeatedly apply the same area, and reduces the risk of missing or uneven application, allowing for efficient use of glue and facilitating application. Additionally, when applying a thick solid glue to narrow or small areas, applying it using the corners of the edge of the solid glue's tip can sometimes result in the glue overflowing from the container, soiling the container or interfering with the removal and attachment of the cap, but the use of the small-diameter first solid glue S can prevent such situations.

[0059] On the other hand, when applying glue to a wide or large area, as shown in Figures 5(c) and 6(c), by rotating the bottom 31, the small diameter (thin) first solid glue S is dispensed from the container body 2, and by rotating the outer tube 21, the large diameter (thick) second solid glue L is dispensed from the container body 2, and glue can be applied to the combined width of the small diameter (thin) first solid glue S and the large diameter (thick) second solid glue L, so that even wide or large area areas can be coated in a short time, making the application work easier. Furthermore, as shown in Figures 5(b) and 6(b), by rotating only the outer tube portion 21, it is possible to dispense only the large-diameter (thick) second solid glue L from the container body 2 and apply only the large-diameter second solid glue L. Depending on the dimensions and shape of the area to be applied, using only the large-diameter second solid glue L makes it possible to apply the glue without it spilling out, and also improves the ease of application work, allowing application to be completed in a short time.

[0060] Thus, with the glue stick container 1 according to this embodiment, the bottom 31 and / or outer tube 21 can be rotated to dispense the narrow-width first solid glue S and / or the wide-width second solid glue L from the outer tube 21 and inner tube 11 depending on the location and application of the glue, and the width of the solid glue to be applied can be changed by rotating the bottom 31 and / or outer tube 21. Because the width of the solid glue to be applied is changed by rotating the bottom 31 and / or outer tube 21, changing the width of the solid glue to be applied can be easily performed. In particular, because the flange 41 is interposed between the bottom 31 and outer tube 21, the operation of rotating the bottom 31 and outer tube 21 independently is simple and easy for the user to understand. In other words, since it is used in the same way as known stick glue containers, it is easy to understand, and by rotating the bottom 31 and / or outer tube 21, the stick-shaped solid glues S, L can be easily inserted and removed from the container body 2 with little force.

[0061] In the glue stick container 1 of this embodiment, the male thread portion 135 on the outer surface of the threaded rod portion 13 and the male thread portion 115 on the outer surface of the inner tube portion 11 have the same threading direction. In the glue stick container 1 of this embodiment, the inner tray portion 12 is threadedly engaged with the threaded rod portion 13, which is integrated with the bottom portion 31. Therefore, when the bottom portion 31 rotates, the inner tray portion 12 moves along the axis O of the threaded rod portion 13 on the threaded rod portion 13. Meanwhile, the outer tray portion 22, which is threadedly engaged with the outer surface of the inner tube portion 11, engages with the outer tube portion 21. Therefore, when the outer tube portion 21 rotates, the outer tray portion 22 moves along the axis O of the inner tube portion 11 on the inner tube portion 11. Therefore, as shown in FIG. 5, when the bottom portion 31 and the outer tube portion 21 rotate in opposite directions, the solid glues S and L are dispensed and retracted from the container body 2. That is, the second solid glue L can be dispensed from the container body 2 by rotating the outer tube 21 in the opposite direction to the rotation direction of the bottom 31 when dispensing the first solid glue S from the container body 2. Also, the dispensed second solid glue L can be retracted into the container body 2 by rotating the outer tube 21 in the opposite direction to the rotation direction of the bottom 31 when retracting the dispensed first solid glue S into the container body 2. However, when implementing the present invention, the threading directions of the male screw portion 135 on the outer peripheral surface of the threaded rod portion 13 and the male screw portion 115 on the outer peripheral surface of the inner tube 11 may be opposite to each other. In this case, the rotation direction of the bottom 31 when the first solid glue S is dispensed from the container body 2 coincides with the rotation direction of the outer tube 21 when the second solid glue L is dispensed from the container body 2, and the rotation direction of the bottom 31 when the first solid glue S is retracted into the container body 2 coincides with the rotation direction of the outer tube 21 when the second solid glue L is retracted into the container body 2.

[0062] When using the solid glues S and L, as with known devices, the cap 3 is removed from the container body 2 to open the top of the container body 2, exposing the first solid glue S and the second solid glue L, and the bottom 31 and / or the outer tube portion 21 is rotated to dispense the first solid glue S and / or the second solid glue L from the tip of the outer tube portion 21 or the inner tube portion 11 for application. The glue stick container 1 of this embodiment accommodates a first solid glue S as a small-diameter, shaft-shaped first solid to be applied in the inner storage space 10 formed by the inner tube portion 11, inner receiving tray portion 12, and threaded rod portion 13, and a second solid glue L as a large-diameter, shaft-shaped second solid to be applied in the outer storage space 20 formed by the inner tube portion 11, outer tube portion 21, and outer receiving tray portion 22. The first solid glue S and the second solid glue L are accommodated in a two-layer structure, with the inside (center side) and the outside surrounding it, and the outer peripheral side of the outer tube portion 21 of the container body 2 is grasped, and the first solid glue S or the second solid glue L, which is protruded from the tip side of the inner tube portion 11 or the outer tube portion 21 by rotating the bottom 31 or the outer tube portion 21, is applied (glued) to the surface to be applied. This glue stick container 1 is used to store and apply solid glues S and L, and compared to starch glue or liquid glue, it can apply the glue neatly in the appropriate amount. Also, like known solid glues, when not in use, the cap 3 is fitted over the container body 2, covering the solid glues S and L with the cap 3 to prevent them from drying out.

[0063] Thus, in the glue stick container 1 of this embodiment, when the bottom 31, which is rotatably attached to the flange 41 integrally formed at the base end of the inner tube 11 at the base end side of the outer tube 21, is rotated, the threaded rod 13, which protrudes toward the interior of the inner tube 11 on the axis O of the bottom 31, rotates within the inner tube 11. This causes the inner receptacle 12, which is threaded onto the threaded rod 13, to move along the axis O of the threaded rod 13. Therefore, the small-diameter first solid glue S, which is contained in the inner storage space 10 defined by the inner tube 11, inner receptacle 12, and threaded rod 13 and whose axial base end side is supported by the inner receptacle 12, can be freely dispensed (protruded and retracted) from the tip side of the inner tube 11 in the direction of the axis O. At this time, since the protrusion 116 protruding from the inner wall surface of the inner tube portion 11 and extending in the direction of the axis O is fitted into the vertical groove portion 126 grooved in the outer wall surface of the inner receptacle portion 12, the movement of the inner receptacle portion 12 in the direction of the axis O is guided by the protrusion 116 of the inner tube portion 11, so that the inner receptacle portion 12 moves (rises and falls) on the threaded rod portion 13 along the direction of the axis O while being restricted from rotating around its axis relative to the threaded rod portion 13.

[0064] That is, by rotating the bottom 31, which is rotatably attached to the flange 41 integrally formed at the base end of the inner tube 11 at the base end side of the outer tube 21, the threaded rod 13 formed integrally with the bottom 31 is rotated inside the inner tube 11, and the inner receptacle 12 screwed onto the threaded rod 13 moves along the axis O of the threaded rod 13 while being guided by the protrusions 116 of the inner tube 11 in the grooves 12 formed on its outer periphery. Thus, the small-diameter first solid glue S, which is contained in the inner storage space 10 defined by the inner tube 11, the inner receptacle 12, and the threaded rod 13 and has one end supported by the inner receptacle 12, can protrude from the opening at the tip of the inner tube 11 by rotating the bottom 31.

[0065] Furthermore, when the outer tube portion 21 is rotated, the outer tray portion 22, which is engaged with the inner peripheral surface of the outer tube portion 21 and is screwed onto the outer peripheral surface of the inner tube portion 11, rotates. As a result, the outer tray portion 22 moves along the axial direction O of the inner tube portion 11. Therefore, the large-diameter second solid glue L, which is accommodated in the outer accommodation space 20 defined by the inner tube portion 11, the outer tray portion 22, and the outer tube portion 21 and whose base end side in the axial direction is supported by the outer tray portion 22, can be freely dispensed (progressed and retracted) from the tip end side in the axial direction of the outer tube portion 21.

[0066] That is, by rotating the outer tube portion 21, the outer tray portion 22, which is disposed between the outer tube portion 21 and the inner tube portion 11 and is screwed onto the inner tube portion 11, and is also engaged with the outer tube portion 21, is rotated, so that the outer tray portion 22, which is screwed onto the inner tube portion 11, moves along the axis O of the inner tube portion 11. Therefore, by rotating the outer tube portion 21, the second solid glue L, which has a large diameter and is accommodated in the outer accommodation space 20 defined by the inner tube portion 11, the outer tray portion 22, and the outer tube portion 21 and one end of which is supported by the outer tray portion 22, can freely protrude from the opening at the tip of the outer tube portion 21.

[0067] In this way, the first solid glue S stored in the inner storage space 10 and held by the inner receiving tray 12 can be dispensed from the tip of the inner tube 11 by rotating the bottom 31 and used for application (gluing). Also, the second solid glue L stored in the outer storage space 20 and held by the outer receiving tray 22 can be dispensed from the tip of the outer tube 21 by rotating the outer tube 21 and used for application. When applying the first solid glue S or the second solid glue L, the axis O direction of the container body 2 may be aligned approximately perpendicular to the surface to be applied, and the tip surface (top surface) of the axis O direction of the first solid glue S or the second solid glue L may be placed against the surface to be applied and slid approximately parallel to the surface to apply the first solid glue S or the second solid glue L, or the axis O direction of the container body 2 may be tilted relative to the surface to be applied, and the peripheral corners of the tip surface of the axis O direction of the first solid glue S or the second solid glue L may be slid approximately parallel to the surface to be applied, to apply the first solid glue S or the second solid glue L.

[0068] Furthermore, the tip end of the spirally formed screw groove / thread of the female screw portion 135 on the outer surface of the threaded rod portion 13 is located a predetermined distance from the tip end of the threaded rod portion 13, and when the threaded rod portion 13 rotates due to the rotation of the bottom portion 31, and the inner receptacle portion 12 that is screwed to it moves along the axis O direction of the threaded rod portion 13, the movement of the inner receptacle portion 12 stops when it reaches the tip edge of the female screw portion 135, and the inner receptacle portion 12 hardly protrudes from the tip end of the inner tube portion 11 and the outer tube portion 21. Furthermore, the tip end of the spirally formed screw groove / thread of the female screw portion 115 on the outer peripheral surface of the inner tube portion 11 is located a predetermined distance from the tip of the inner tube portion 11, and when the outer receptacle portion 22 rotates due to the rotation of the outer tube portion 21, and the outer receptacle portion 22 moves along the axial line O of the inner tube portion 11 to which the outer receptacle portion 22 is screwed, the movement of the outer receptacle portion 22 ends when it reaches the tip edge of the female screw portion 115, and the outer receptacle portion 22 hardly protrudes from the tip of the inner tube portion 11 and the outer tube portion 21. As a result, even when the remaining amount of the first solid glue S or the second solid glue L becomes small and their lengths become shorter, they do not protrude too far from the tip of the inner tube portion 11 and the outer tube portion 21, so the first solid glue S or the second solid glue L is less likely to bend or break during application, allowing for smooth application.

[0069] Now, assuming that the diameter of the first solid glue S is d1, the stress of the first solid glue S is σ1, the diameter of the second solid glue L is d2, the stress of the second solid glue L is σ2, and the thickness of the peripheral wall of the inner tube portion 11 is t (see Figure 6), when the same material is used for the first solid glue S and the second solid glue L, the condition under which the stress of the first solid glue S and the second solid glue L will be the same is d2 = √2(d1 + √2t). However, since the minimum width of a commercially available narrow stick glue is, for example, 6 mm, if the diameter of the first solid glue S is d1 = 6 mm and the thickness of the peripheral wall of the inner tube portion 11 is t = 2 mm, then the diameter of the second solid glue L will be d2 = 12.5 mm according to the above formula. If the diameter d2 of the second solid glue L is 12.5 mm or more, it will be strong enough to withstand breaking. Furthermore, because the width of commercially available narrow glue sticks is, for example, about 20 mm, the external dimensions of a conventional commercially available glue stick can be kept to a similar level even when storing a two-layer structure consisting of a small-diameter first solid glue S and a large-diameter second solid glue L. Therefore, the glue stick container 1 according to this embodiment has a smart appearance, does not take up much space for storage, and can be carried around in a pencil case, pen case, etc., just like conventional commercially available glue sticks.

[0070] For example, by designing the outer tube 21 to be the same size as a conventional commercially available thick glue stick product (e.g., diameter d2 of the second solid glue L = 26 mm), and the inner tube 11 disposed inside the outer tube 21 to be the same size as a conventional thin glue stick product (e.g., diameter d1 of the first solid glue S = 13 mm), it is possible to use a single glue stick container 1 to dispense and apply only the thin first solid glue S from the inner tube 11, or to dispense and apply only the thick second solid glue L from between the inner tube 11 and the outer tube 21, or to dispense and apply both the thin first solid glue S and the thick second solid glue L to approximately the same lengths from the inner tube 11 and the outer tube 21 simultaneously. Furthermore, by using the thin first solid glue S for narrow, fine application areas, the small diameter and narrow application surface of the first solid glue S reduces the amount of glue spilling out during application, thereby reducing wasted glue. It also allows for even application to small areas and corners, preventing poor adhesion. On the other hand, for wide areas, by using both the thin first solid glue S and the thick second solid glue L, which are both dispensed at equal lengths from the inner tube portion 11 and the outer tube portion 21, it is possible to apply glue to a wide area in a short time. This makes it highly convenient. Of course, if it is about the same size as a conventional glue stick product, it will be a sleek looking glue stick container 1 that does not take up much space and is easy to carry in a pencil case, etc.

[0071] Thus, in the glue stick container 1 of this embodiment, the first solid glue S as a small-diameter, shaft-shaped first solid application material is accommodated in the inner storage space 10 formed by the inner tube 11, inner receptacle 12, and threaded rod 13, and the second solid glue L as a large-diameter, shaft-shaped second solid application material is accommodated in the outer storage space 20 formed by the inner tube 11, outer tube 21, and outer receptacle 22, and the first solid glue S and the second solid glue L can be independently dispensed from the container body 2. That is, the first solid glue S can be dispensed from the inner tube 11 by rotating the bottom 31, and the second solid glue L can be dispensed from between the inner tube 11 and outer tube 21 by rotating the outer tube 21. Therefore, depending on the area and material of the part to be coated, it is possible to use only the first solid glue S, only the second solid glue L, or both the first solid glue S and the second solid glue L at the same time, and the first solid glue S and the second solid glue L can be used appropriately.

[0072] The glue stick container 1 of this embodiment contains two layers, with the first solid glue S as the inner layer and the second solid glue L as the outer layer, and it is possible to store solid glues S and L of different types (components, formulations, etc.) in a single container. That is, different types of first solid glue S and second solid glue L can be stored. Therefore, for example, a hard first solid glue S for narrow widths can be used, and a soft or loose second solid glue L can be used. By using the hard first solid glue S for narrow widths at corners and edges of the object, it is possible to apply the glue with reduced overflow. Meanwhile, in central areas surrounded by corners and edges, large areas, and areas where overflow is not a concern, the soft second solid glue L alone or a combination of the second solid glue L and the first solid glue S can be used, allowing for quick and wide application and improving application efficiency.

[0073] As explained above, the glue stick container 1 as a dispensing container according to this embodiment comprises an inner tube 11 having a male screw 115 extending in the axial direction O on its outer circumferential side surface, an inner receiving tray 12 disposed within the inner tube 11 and having a female screw 125 on its inner circumferential side surface, a threaded rod 13 disposed within the inner tube 11 and having a male screw 135 extending in the axial direction O on its outer circumferential side surface with which the inner receiving tray 12 is screwed, an outer tube 21 disposed around the outer periphery of the inner tube 11, and an outer tube 21 disposed between the inner tube 11 and the outer tube 21 and having a female screw 225 on its inner circumferential side surface with which the inner tube 11 is screwed. Both comprise an outer receiving tray portion 22 engaged with the outer tube portion 21, a bottom portion 31 integrated with the base end of the threaded rod portion 13 in the axial direction O, and a flange portion 41 integrated with the base end of the inner tube portion 11 in the axial direction O and interposed between the outer tube portion 21 and the bottom portion 31, and a first solid glue S as a small-diameter, shaft-shaped first applied solid is accommodated in the inner storage space 10 formed between the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13, and a second solid glue L as a large-diameter, shaft-shaped second applied solid is accommodated in the outer storage space 20 formed by the inner tube portion 11, the outer tube portion 21, and the outer receiving tray portion 22.

[0074] In other words, in the stick glue container 1 as a dispensing container in this embodiment, an inner tube portion 11 has an outer peripheral side surface with an external thread portion 115 extending in the direction of the axis O, and inside the tube are arranged a threaded rod portion 13 having an outer peripheral side surface with an external thread portion 135 extending in the direction of the axis O, and an inner receiving tray portion 12 having an inner peripheral side surface with an internal thread portion 125 and screwed onto the threaded rod portion 13, thereby forming an inner storage space 10 between the inner tube portion 11, the inner receiving tray portion 12, and the threaded rod portion 13 for storing a first solid glue S as a small-diameter first application solid. An outer tube 21 is disposed around the outer periphery of the inner tube 11, and an outer tray 22 has a female thread 225 on its inner peripheral surface and is threadedly engaged with the inner tube 11, and is disposed between the outer tube 21 and the inner tube 11, forming an outer storage space 20 for storing a second solid glue L as a large-diameter second solid application material between the outer tube 21, the outer tray 22, and the inner tube 11. A bottom 31 is integrated with the axial base end of the threaded rod 13, and a flange 41 is integrated with the axial base end of the inner tube 11, with the flange 41 being interposed between the bottom 31 and the outer tube 21.

[0075] Therefore, when the bottom portion 31 is rotated, the threaded rod portion 13 integrated with the bottom portion 31 rotates, and the inner receptacle portion 12 screwed onto the threaded rod portion 13 moves along the axis O of the threaded rod portion 13. As a result, the first solid glue S as a small-diameter first applied solid material contained in the inner storage space 10 formed between the inner tube portion 11, the inner receptacle portion 12, and the threaded rod portion 13 can be freely dispensed from between the inner tube portion 11 and the threaded rod portion 13. Furthermore, when the outer tube portion 21 is rotated, the outer receiving tray portion 22, which is engaged with the outer tube portion 21 and is screwed onto the inner tube portion 11, moves along the axis O of the inner tube portion 11. As a result, the second solid glue L, which serves as a large-diameter second solid application material and is accommodated in the outer accommodating space 20 formed between the inner tube portion 11, the outer receiving tray portion 22, and the outer tube portion 21 around the outer periphery of the inner accommodating space 10, can be freely dispensed from the inner tube portion 11. In this way, by rotating the bottom 31, the first solid glue S as the first application solid material having a small diameter can freely protrude from the inner tube portion 11, while by rotating the outer tube portion 21, the second solid glue L as the second application solid material having a large diameter can freely protrude from the outer tube portion 21.

[0076] Therefore, by rotating only the bottom portion 31 and moving the inner receiving tray portion 12 toward the tip end of the threaded rod portion 13 in the direction of its axis O, only the first solid glue S as the small-diameter first solid to be applied can be dispensed from the inner tube portion 11, and application can be performed using the application surface of the small-diameter tip end of the first solid glue S. Alternatively, by rotating only the outer tube portion 21 and moving the outer receiving tray portion 22 toward the tip end of the inner tube portion 11 in the direction of its axis O, only the second solid glue L can be dispensed. The first solid glue S and the second solid glue L can be dispensed from the outer tube portion 21 and application can be performed using the application surface of the large-diameter tip of the second solid glue L, or the bottom portion 31 can be rotated and the outer tube portion 21 can be rotated, i.e., the bottom portion 31 and the outer tube portion 21 can be rotated separately, and the first solid glue S and the second solid glue L can be dispensed from the inner tube portion 11 and the outer tube portion 21 and application can be performed by combining the application surface of the small-diameter tip of the first solid glue S and the application surface of the large-diameter tip of the second solid glue L.

[0077] Thus, the glue stick container 1 as a dispensing container according to this embodiment can be switched between a wide and a narrow application surface, allowing the shape and area of ​​the application surface to be changed. In other words, it allows for both thin and thick applications. Therefore, using the small-diameter (thin) first solid glue S alone makes it possible to apply the glue to narrow or small areas without spilling over, while using the large-diameter (thick) second solid glue L alone or simultaneously (using both) the first solid glue S and the second solid glue L makes it possible to apply the glue to wide or large areas in a short time. The ability to selectively apply thin or thick glue prevents glue waste and unevenness caused by spilling over or multiple applications, and also reduces the effort and time required for application, making it highly convenient. Moreover, the solid glues S and L can be accommodated as different types of solid coating materials, and the solid glues S and L can be coated separately or simultaneously as different types of solid coating materials.

[0078] Furthermore, in the glue stick container 1 as a dispensing container of the above embodiment, the inner tube 11 has a protrusion 116 on its inner peripheral surface as a protruding guide extending in the direction of the axis O, and the inner tray 12 has a vertical groove 126 on its outer peripheral surface as a fitting that fits onto the protrusion 116. Therefore, because the protrusion 116 as a guide of the inner tube 11 and the vertical groove 126 as a fitting of the inner tray 12 are fitted together, the inner tray 12 threaded onto the threaded rod 13 moves along the axis O of the threaded rod 13 while being guided by the protrusion 116 as a guide of the inner tube 11. Therefore, when the bottom 31 and the threaded rod 13 rotate, the inner tray 12 threaded onto them does not rotate itself, i.e., it can be reliably moved along the axis O of the threaded rod 13 without spinning, resulting in excellent usability.

[0079] In the above embodiment, it was explained that a protrusion (convex portion) 216 is provided on the inner peripheral side surface of the outer tube portion 21 and a groove (concave portion) 226 is provided on the outer peripheral surface of the outer tray portion 22, and that the outer tube portion 21 and the outer tray portion 22 engage and work in an interlocking relationship when the two are fitted together. However, when implementing the present invention, the formation of the concave and convex portions (groove-shaped and protrusion-shaped) may be reversed, and a protrusion (convex portion) may be provided on the outer peripheral side surface of the outer tray portion 22 and a groove may be provided on the inner peripheral side surface of the outer tube portion 21, and that the outer tube portion 21 and the outer tray portion 22 may engage and work in an interlocking relationship when the two are fitted together. In addition, the protrusion (convex portion) 116 serving as a guide portion on the inner side surface of the inner tube portion 11 and the groove (concave portion) 126 serving as a fitting portion on the outer side surface of the inner receptacle portion 12 may have the unevenness (groove-shaped and protrusion-shaped) reversed, with the protrusion (convex portion) provided on the outer side surface of the inner receptacle portion 12 and the groove provided on the inner side surface of the inner tube portion 11.

[0080] When carrying out the present invention, the inner cylindrical portion 11 and the outer cylindrical portion 21 are not limited to cylindrical portions having a substantially circular (perfect circle) cross section, but may be cylindrical portions having an elliptical (oval) cross section, or polygonal cross sections such as triangular or rectangular, i.e., polygonal cylindrical portions having a non-circular polygonal cross section. Furthermore, the direction of the axis O refers to the up-down direction along the central axis O, the radial direction refers to the direction along a straight line perpendicular to the axis O, the circumferential direction refers to the direction going around the axis O, the longitudinal section refers to a section including the axis O, and the transverse section refers to a section perpendicular to the longitudinal section.

[0081] In the above embodiment, the dispensing container for containing glue sticks has been described as a glue stick container, which is a solid glue applicator that is applied to areas requiring adhesion. However, when implementing the present invention, the object contained in the dispensing container is not limited to a stick-shaped (rod-shaped, cylindrical, column-shaped, etc.) glue stick, and any applicable solid may be used, including stick-shaped (rod-shaped, cylindrical, column-shaped, etc.) cosmetics such as lipstick, lip balm, stick eye shadow, crayons, etc. In other words, the dispensing container of the present invention can be used as a container for containing stick-shaped (stick-shaped) lipstick, lip balm, stick eye shadow, crayons, etc. In particular, since the dispensing container contains a two-layer application solid, it is possible to apply different types of application solids separately or simultaneously. Therefore, when application solids of different colors are used, it is possible to apply the two colors separately or simultaneously. [Explanation of symbols]
