Summary of the Invention

Problems to be Solved by the Invention

[0005] Incidentally, the dispensing container described in Patent Document 2 is discarded after the contained rod-shaped contents have been used up. Therefore, from the viewpoint of resource conservation and reduction of environmental burden, there is a need for a dispensing container in which some components such as the base can be reused, and in which a used cartridge containing the used rod-shaped contents can be replaced with a new cartridge.

[0006] Furthermore, when storing rod-shaped contents in a cartridge, a method is typically used in which the molten contents are filled into an empty cartridge and then solidified. There are two such filling methods: one in which a filling nozzle is inserted through the opening from which the rod-shaped contents are dispensed and the contents are filled into the cartridge from this nozzle (hereinafter referred to as "direct filling"), and another in which a filling nozzle is inserted through an insertion opening in the bottom wall that supports the rod-shaped contents and the contents are filled into the cartridge (hereinafter referred to as "back filling"). These filling methods are selected according to the tip shape of the rod-shaped contents and the manufacturing process. The configuration of the cartridge is usually changed according to the filling method. Therefore, when changing the configuration of the cartridge according to the filling method, it is preferable to minimize the changes in the configuration in terms of cost reduction and resource conservation, and such dispensing containers are in demand.

[0007] In view of these points, the present invention aims to provide a dispensing container and a cartridge for a dispensing container that allows used cartridges to be replaced with new cartridges and minimizes the number of components that need to be changed depending on the filling method.

The inner tray may be one in which the radially inner side of the second engaging portion in the bottom wall is closed.

[0010] The inner tray may have an opening radially inward of the second engaging portion in the bottom wall.

[0011] Preferably, the shaft has a retaining portion that prevents the shaft from coming out of the rotating body.

[0012] The cartridge body has an engagement portion on the tray side and an engagement portion on the cartridge body side that engage with each other when the tray is retracted relative to the cartridge body, and the engagement portion on the tray side is connected to a weakened portion provided on the tray, and when the weakened portion breaks, it undergoes elastic deformation. The cartridge body side engagement portion becomes disengaged.The cartridge body side engaging portion is configured such that, and / or, the cartridge body side engaging portion is connected to a weakened portion provided on the cartridge body, and when the weakened portion breaks, it undergoes elastic deformation. This disengages the intermediate plate side engagement portion. It is preferable that it be configured in such a way.

[0013] Preferably, the rotating body has a restricting wall located radially outward of the elastic piece that restricts the elastic deformation of the elastic piece.

[0014] The base, the cartridge, and the rod-shaped contents are flattened in plan view, Either the base or the cartridge has an elastically deformable claw portion on the longer side which is flattened, Preferably, either the base or the cartridge has a hole that engages with the claw portion when the cartridge is mounted on the base, thereby holding the cartridge in place.

[0015] The present invention also relates to a cartridge for a dispensing container, which is mounted on a base equipped with a rotating body, and which dispenses a rod-shaped contents when the rotating body is rotated, wherein the base rotates together with the rotating body and is movable forward and backward relative to the rotating body, and is configured to include a shaft having a cylindrical portion extending along the central axis of the rotating body, a first engaging portion projecting radially outward and forming an outward claw shape connected to the cylindrical portion, and a first screw-shaped male thread provided on the outer circumferential surface of the cylindrical portion, and a bottom wall that supports the rod-shaped contents, and a middle tray having a second engaging portion located radially outward of the cylindrical portion and projecting radially inward and forming an inward claw shape connected to the bottom wall, before An elastic piece located radially outward of the cylindrical portion and extending along the central axis of the rotating body, and provided on the inner circumferential surface of the elastic piece female Having a screw-shaped second threaded portion, The rod-shaped contents and the inner tray are surrounded and mounted on the base. The cartridge body is equipped with a first engaging portion and a second engaging portion that are detachably engaged, and a first screw portion and a second screw portion that are detachably screwed together, and when the rotating body is rotated, the middle plate moves forward and backward together with the shaft body. Furthermore, the inner tray is provided with an insertion opening that penetrates the bottom wall on the radially inward side of the second engaging portion in the bottom wall, and a cylindrical portion that surrounds the insertion opening and extends from the bottom wall toward the receding side of the inner tray, and when the dispensing container cartridge is not mounted on the base, the filling nozzle can be inserted into the cylindrical portion and the insertion opening to fill the internal space of the dispensing container cartridge with the molten rod-shaped contents. It is also a cartridge for dispensing containers.

Advantages of the Invention

[0016] For the feeding container of the present invention configured as described above, when the rotating body is rotated, the middle plate moves forward and backward together with the shaft body, so that the rod-shaped content held on the middle plate can be fed out or fed into the cartridge body. Further, since the first engaging portion and the second engaging portion are detachably engaged, and the first screwing portion and the second screwing portion are detachably screwed, after the rod-shaped content is used up, the cartridge mounted on the base can be removed by separating the middle plate and the cartridge body from the shaft body, and a new cartridge can be mounted on the original base in the reverse procedure. Furthermore, the cartridge can be composed of a middle plate and a cartridge body, and the number of members to be discarded after the rod-shaped content is used up can be reduced, so that it is excellent in resource saving and reduction of environmental load. In addition, since the second engaging portion provided on the bottom wall of the middle plate is located on the outer side in the radial direction of the cylindrical portion and protrudes inward in the radial direction to form an inward claw shape, a space is created on the inner side in the radial direction of the second engaging portion on the bottom wall. That is, if an insertion port is provided on the bottom wall using the space, it becomes a middle plate for backfilling, and if the bottom wall is closed without using the space, it becomes a middle plate for direct filling. Therefore, when selecting two filling methods, only the middle plate needs to be changed, and the members to be changed according to the filling method can be minimized.

Mode for Carrying Out the Invention

[0018] Hereinafter, an embodiment of the dispensing container and the cartridge for the dispensing container (sometimes simply referred to as the cartridge in this specification) according to the present invention will be described with reference to the drawings. In the following description, the vertical direction refers to the direction along the central axis O shown in the drawings (the central axis of the rotating body 5 described below). The radial direction refers to the direction perpendicular to the central axis O in a plane perpendicular to the central axis O, and the circumferential direction refers to the direction of rotation around the central axis O in this plane.

[0019] First, let's explain the configuration of the illustrated dispensing container 1. As shown in Figures 1 and 2, the dispensing container 1 of this embodiment consists of a base 2, a cartridge 7, and a cap 11. The base 2 consists of a base body 3, a bottom cover 4, a rotating body 5, and a shaft 6, while the cartridge 7 consists of a cartridge body 8, an inner tray 9A, and a cover 10. All of these components are shaped around a central axis O, and in this embodiment, all are made of synthetic resin. Inside the cartridge 7, as shown in Figure 7, there is a rod-shaped contents C, but the rod-shaped contents C is omitted in Figures 1 and 2. The inner tray 9A is an inner tray for bag filling, as will be described later.

[0020] The base body 3 is equipped with a cylindrical lower outer peripheral wall 3a. The lower outer peripheral wall 3a, like the upper outer peripheral wall 8a of the cartridge body 8 shown in Figure 5, has a flattened shape (track shape in this embodiment) in plan view. A fitting wall 3b, which is thinner than the lower outer peripheral wall 3a, is provided at the lower end of the lower outer peripheral wall 3a. In the middle of the lower outer peripheral wall 3a in the vertical direction, in a plan view, there is an opening 3c that penetrates the lower outer peripheral wall 3a radially, as shown in Figure 2. And in the upper part of the lower outer peripheral wall 3a, in a plan view, there is a pair of holes 3d that penetrate the lower outer peripheral wall 3a radially, as shown in Figure 1.

[0021] The bottom cover 4, like the lower outer peripheral wall 3a, is shaped like a track in plan view. The outer edge of the bottom cover 4 is provided with a fitting recess 4a that fits into the fitting wall 3b. The central part of the bottom cover 4 is provided with an inner annular wall 4b that forms an annular shape.

[0022] As shown in Figures 1, 2, and 3, the rotating body 5 is provided with a cylindrical wall 5a extending along the central axis O. The cylindrical wall 5a has a circular outer surface and a polygonal inner surface (in this embodiment, two regular hexagons offset by 30° around the central axis O). The outer diameter of the cylindrical wall 5a is slightly smaller than the inner diameter of the inner annular wall 4b, and the cylindrical wall 5a is radially supported by the inner annular wall 4b. That is, the rotating body 5 is rotatably supported relative to the bottom cover 4 by the cylindrical wall 5a and the inner annular wall 4b. Above the cylindrical wall 5a, a stopper 5b is provided that protrudes radially inward. Above the stopper 5b, an annular regulating wall 5c is provided.

[0023] The rotating body 5 also includes an operating wall 5d that extends radially outward from the cylindrical wall 5a and then downward. As shown in Figure 2, the operating wall 5d is located where the opening 3c is provided, and the outer surface of the operating wall 5d is exposed to the outside through the opening 3c.

[0024] As shown in Figures 1, 2, and 4, the shaft body 6 has a cylindrical tubular portion 6a extending along the central axis O. The outer circumferential surface of the tubular portion 6a is provided with a spirally extending male screw-shaped first threaded portion 6b. The upper part of the tubular portion 6a is provided with a first engaging portion 6c that protrudes radially outward, forming an outward-facing claw shape and connecting to the tubular portion 6a. The first engaging portion 6c is elastically deformable radially inward relative to the tubular portion 6a.

[0025] The shaft 6 also has a plate-shaped retaining portion 6e that extends radially outward from the lower end of the cylindrical portion 6a. In this embodiment, the retaining portion 6e also has the function of preventing rotation relative to the inner circumferential surface of the cylindrical wall 5a. In order to provide the rotation prevention function, the retaining portion 6e in this embodiment is shaped into a regular hexagon to correspond to the shape of the inner circumferential surface of the cylindrical wall 5a. Note that the shape of the inner circumferential surface of the cylindrical wall 5a and the shape of the retaining portion 6e are not limited to a regular hexagon, but may be triangular or square. The retaining portion 6e is also shaped to be inserted inside the cylindrical wall 5a. That is, when the rotating body 5 is rotated with the retaining portion 6e inserted inside the cylindrical wall 5a, the shaft 6 rotates together with the rotating body 5. In this state, the shaft 6 can move relative to the rotating body 5 in a direction along the central axis O, but since the retaining portion 6e is larger than the stopper 5b, the shaft 6 will not come out upward relative to the rotating body 5.

[0026] As shown in Figure 5(a), the cartridge body 8 has a cylindrical upper outer peripheral wall 8a that is track-shaped in plan view. Here, the upper opening of the upper outer peripheral wall 8a is referred to as the dispensing port 8a1. A plate-shaped wall 8b extending horizontally is provided at the lower end of the upper outer peripheral wall 8a. A circular through hole 8c centered on the central axis O is provided in the center of the plate-shaped wall 8b. The plate-shaped wall 8b also has a pair of elastic pieces 8d extending longitudinally outward from the circular through hole 8c in plan view. In this embodiment, the elastic piece 8d is shaped such that one end is connected to the plate-shaped wall 8b, and from there it extends downward, then radially inward, and then further downward. The elastic piece 8d is elastically deformable so as to bend radially outward starting from the part that connects to the plate-shaped wall 8b. Furthermore, a second threaded part 8e, which is a female screw shape extending in a spiral, is provided on the inner circumferential surface of the lowest part of the elastic piece 8d.

[0027] Furthermore, the plate-like wall 8b is provided with a rectangular through-hole 8f, which is rectangular in shape in a plan view, located longitudinally outward in a plan view relative to the elastic piece 8d. Inside the rectangular through-hole 8f, a cartridge body-side engaging portion 8g is provided. In this embodiment, the cartridge body-side engaging portion 8g is shaped like a claw, as shown in Figure 5(b). The cartridge body-side engaging portion 8g is connected to the plate-like wall 8b on its longitudinally outward side and is elastically deformable radially outward. As shown in Figure 5(a), inside the rectangular through-hole 8f, a thin, narrow weakening portion 8h is provided, located in the short direction of the plate-like wall 8b and connecting the cartridge body-side engaging portion 8g and the plate-like wall 8b. The weakening portion 8h is breakable, and in the broken state, the cartridge body-side engaging portion 8g is elastically deformable. However, when the weakening portion 8h is connected to the cartridge body-side engaging portion 8g and the plate-like wall 8b, the elastic deformation of the cartridge body-side engaging portion 8g is suppressed.

[0028] Furthermore, the cartridge body 8 is provided with a cylindrical guide 8j that extends downward from the plate-shaped wall 8b. In a plan view, the longitudinal outer side of the guide 8j is provided with a claw portion 8k that is elastically deformable radially inward and has a bulge on its radially outer side. As shown in Figure 1, the radially outward bulge portion of the claw portion 8k is inserted into the hole 3d from the radially inward side. The upper surface of this bulge portion extends horizontally and engages with the upper surface of the hole 3d. The lower surface of this bulge portion is provided with an inclined surface 8m that slopes radially inward downward.

[0029] As shown in Figures 1, 2, and 6, the inner tray 9A is located radially inward of the upper outer peripheral wall 8a and has a plate-shaped bottom wall 9a that is slightly smaller than the upper outer peripheral wall 8a in plan view. The outer edge of the bottom wall 9a is provided with an inner tray outer peripheral wall 9b that extends upward along the inner peripheral surface of the upper outer peripheral wall 8a. Radially inward of the inner tray outer peripheral wall 9b is provided with a protruding wall 9c that slopes radially outward as it extends upward. Although not shown in the figures, a rod-shaped contents are provided inside the inner tray 9A and are supported from below the bottom wall 9a. The protruding wall 9c is embedded in the rod-shaped contents supported by the bottom wall 9a.

[0030] A circular insertion opening 9d is provided in the center of the bottom wall 9a, penetrating the bottom wall 9a. A cylindrical insertion tube 9e is provided on the lower surface of the bottom wall 9a, surrounding the insertion opening 9d. The insertion opening 9d and the insertion tube 9e are the parts into which a filling nozzle for forming a rod-shaped contents is inserted, as will be described later. As shown in Figure 1, a second engaging portion 9g is provided on the lower surface of the bottom wall 9a, located radially outward from the cylindrical portion 6a and protruding radially inward, forming an inward claw shape that connects to the bottom wall 9a.

[0031] Furthermore, the bottom wall 9a is provided with a tray-side engaging portion 9f on its lower surface. As shown in Figure 1, the tray-side engaging portion 9f in this embodiment is shaped like a claw and can be engaged with the cartridge body-side engaging portion 8g.

[0032] The cover 10 is provided with a cover top wall 10a that closes the dispensing opening 8a1. In this embodiment, the cover top wall 10a has a shape in which the central part extends horizontally and curves downward towards the outer edge. The outer edge of the cover top wall 10a is inserted inside the upper outer peripheral wall 8a, and the cover 10 is fitted and held in place on the cartridge body 8. The outer edge of the cover top wall 10a is also provided with a cover outer peripheral wall 10b that extends upward and whose upper end widens radially outward.

[0033] The cap 11 comprises a plate-shaped cap top wall 11a located above the cover 10, and a cap outer peripheral wall 11b extending downward from the outer edge of the cap top wall 11a, surrounding the cover outer peripheral wall 10b, the upper outer peripheral wall 8a, the lower outer peripheral wall 3a, the claw portion 8k, etc. The cap outer peripheral wall 11b is configured to be detachably fitted onto the lower outer peripheral wall 3a, and the cap 11 is held by the base body 3.

[0034] Next, the method of filling the cartridge 7 with contents by back filling will be explained with reference to Figure 7. First, the inner tray 9A is inserted into the cartridge body 8, and the cartridge body side engaging portion 8g and the inner tray side engaging portion 9f are engaged. As a result, the inner tray 9A is held in the cartridge body 8 with its bottom wall 9a close to the plate-shaped wall 8b. In this state, the weakened portion 8h shown in Figure 5(a) is connected to the cartridge body side engaging portion 8g. That is, since the cartridge body side engaging portion 8g is engaged with the inner tray side engaging portion 9f in a state where elastic deformation is suppressed, the inner tray 9A is prevented from coming out of the cartridge body 8. After fitting the cover 10 onto the cartridge body 8, the cartridge 7 is displaced to an inverted position so that the cover 10 is positioned downwards, as shown in Figure 7(a). As described above, the upper end of the outer peripheral wall 10b of the cover widens radially outward, so when the cartridge 7 is placed on a desk or the like, the cartridge 7 can be stably supported in an inverted position.

[0035] Then, the filling nozzle N is brought close to the inverted cartridge 7 from above and inserted into the insertion tube 9e and the insertion opening 9d. The molten contents are then discharged from the filling nozzle N into the internal space partitioned by the cover 10 and the upper outer peripheral wall 8a, filling this internal space. After the required amount of contents has been filled, the contents are allowed to solidify in the internal space, so that a rod-shaped contents C is formed inside the cartridge 7 as shown in Figure 7(b).

[0036] Next, the method of using the dispensing container 1 will be explained with reference to the drawings. Figures 1 and 2 show the state immediately after the cartridge 7, which has the rod-shaped contents C shown in Figure 7, is attached to the base 2 (the rod-shaped contents C are not shown). When the cartridge 7 is attached to the base 2, the claw portion 8k is engaged with the hole portion 3d, so the cartridge 7 will not come off the base 2 unintentionally. The second engaging portion 9g is located above the first engaging portion 6c and the two are in a disengaged state, while the inner tray side engaging portion 9f is engaged with the cartridge body side engaging portion 8g, so the inner tray 9A will not come out of the cartridge body 8. In this state, the first threaded portion 6b and the second threaded portion 8e are threaded together. The lower end of the elastic piece 8d is located radially inward of the regulating wall 5c, and excessive elastic deformation of the elastic piece 8d radially outward is restricted by the regulating wall 5c.

[0037] Next, after removing the cover 10 and cap 11, the rotating body 5 is rotated in a direction such that the first threaded portion 6b rises relative to the second threaded portion 8e. As described above, when the rotating body 5 is rotated, the shaft body 6 also rotates, so the shaft body 6 rises relative to the cartridge body 8 due to the engagement of the first threaded portion 6b and the second threaded portion 8e, as shown in Figure 8. As described above, the first engaging portion 6c is elastically deformable radially inward relative to the cylindrical portion 6a. Therefore, as the shaft body 6 rises, the first engaging portion 6c overcomes the second engaging portion 9g and engages with it. As a result, the inner tray 9A can be moved up and down together with the shaft body 6 in accordance with the rotation of the rotating body 5, so that the rod-shaped contents (not shown) supported by the bottom wall 9a of the inner tray 9A can be dispensed from the dispensing opening 8a1 of the cartridge body 8 and applied to the application target, and after application the rod-shaped contents can be dispensed and housed inside the cartridge body 8.

[0038] Furthermore, when the inner tray 9A is initially raised, the cartridge body-side engaging portion 8g, which engages with the inner tray-side engaging portion 9f, is also raised. As a result, the weakened portion 8h shown in Figure 5(a) breaks, and the cartridge body-side engaging portion 8g becomes elastically deformable. That is, after the weakened portion 8h breaks, when the inner tray 9A is lowered, the cartridge body-side engaging portion 8g elastically deforms and becomes disengaged from the inner tray-side engaging portion 9f (see Figure 10). Therefore, the cartridge body-side engaging portion 8g does not hinder the upward movement of the inner tray 9A.

[0039] After extending the tray 9A to the upper end of the cartridge body 8 and using up the rod-shaped contents, the used cartridge 7 can be replaced with a new cartridge 7. To replace the cartridge, as shown in Figure 9, the claw portion 8k of the used cartridge 7 attached to the base 2 is pressed radially inward. This causes the claw portion 8k to bend radially inward, releasing the engagement between the claw portion 8k and the hole portion 3d, allowing the cartridge 7 to be pulled up relative to the base 2. When the cartridge 7 is pulled up, the lower end of the elastic piece 8d rises above the regulating wall 5c, so the elastic piece 8d becomes capable of elastically deforming radially outward. Also, as described above, the first engagement portion 6c is engaged with the second engagement portion 9g, so when the cartridge 7 is pulled up, the shaft 6 is also pulled up along with the tray 9A. However, when the shaft 6 is pulled up, the retaining portion 6e engages with the stopper 5b, so the shaft 6 does not come out upward relative to the rotating body 5.

[0040] As the cartridge 7 is pulled up, the cartridge body 8 rises relative to the shaft 6 and the inner tray 9A. At this time, the first threaded portion 6b and the second threaded portion 8e are threaded together, but the elastic piece 8d elastically deforms radially outward, releasing the threading between them, thus allowing the cartridge body 8 to rise relative to the shaft 6.

[0041] As the cartridge 7 continues to be pulled up, and the cartridge body 8 comes into contact with the inner tray 9A from below, the inner tray 9A is also pulled up along with the cartridge body 8. The force at this time causes the first engaging portion 6c to elastically deform radially inward, releasing the engagement between the second engaging portion 9g and the first engaging portion 6c, and the inner tray 9A can be separated from the shaft 6 as shown in Figure 10. In other words, in the dispensing container 1 of this embodiment, the only components that are removed from the base 2 as cartridge 7 are the cartridge body 8 and the inner tray 9A. After the engagement between the second engaging portion 9g and the first engaging portion 6c is released, the shaft 6 moves downward due to its own weight.

[0042] After removing the used cartridge 7, a new cartridge 7 can be attached to the base 2 by inserting it from above the base 2. As described above, the lower surface of the claw portion 8k is provided with an inclined surface 8m that slopes radially inward toward downward. That is, when the cartridge 7 is inserted into the base body 3, the inclined surface 8m contacts the upper end surface of the lower outer peripheral wall 3a, causing the claw portion 8k to bend radially inward, so that the cartridge 7 can be attached to the base body 3 without pressing the claw portion 8k with a finger.

[0043] As described above, the dispensing container 1 of this embodiment allows the base 2 and cap 11 to be reused after the rod-shaped contents have been used, thus offering advantages over conventional dispensing containers such as those described in Patent Document 2 in terms of resource conservation and reduction of environmental impact.

[0044] In the dispensing container 1 of this embodiment, it is also possible to form rod-shaped contents by direct filling by using the inner tray 9B shown in Figure 11 instead of the inner tray 9A for back filling described above.

[0045] The inner plate 9B shown in Figure 11 has the same bottom wall 9a, outer peripheral wall 9b, protruding wall 9c, inner plate side engaging portion 9f, and second engaging portion 9g as the inner plate 9A described above, but the insertion opening 9d and insertion cylinder 9e described above have been eliminated. In other words, the radially inner side of the second engaging portion 9g is closed off in the bottom wall 9a of the inner plate 9B.

[0046] Figure 12 shows the process of filling a cartridge 7 with contents using a tray 9B by direct filling. Even when performing direct filling, the tray 9B is inserted into the cartridge body 8, and the engaging portion 8g on the cartridge body side and the engaging portion 9f on the tray side are engaged.

[0047] Then, as shown in Figure 12(a), the filling nozzle N is brought close to the upright cartridge 7 from above and inserted into the dispensing port 8a1. The molten contents are then discharged from the filling nozzle N into the internal space partitioned by the bottom wall 9a and the upper outer peripheral wall 8a, filling this internal space. After the required amount of contents has been filled, the contents are allowed to solidify in the internal space, so that a rod-shaped contents C is formed inside the cartridge 7, as shown in Figure 12(b).

[0048] Furthermore, since the shape of the second screw portion 8e and the second engaging portion 9g of the cartridge 7 using the middle tray 9B is the same as that of the cartridge 7 using the middle tray 9A, it can be mounted on the base 2 and the rod-shaped contents C can be used as described above.

[0049] The dispensing container 1 may be configured as shown in Figures 13 and 14. The dispensing container 1 shown in Figures 13 and 14 has a configuration that is generally similar to that shown in Figures 1 and 2, except that it uses an inner tray 9C instead of an inner tray 9A.

[0050] The intermediate plate 9C has the same bottom wall 9a, intermediate plate outer wall 9b, protruding wall 9c, insertion opening 9d, and intermediate plate side engaging portion 9f as the intermediate plate 9A described above, but the insertion cylinder 9e described above has been eliminated. In addition, the second engaging portion 9g has been replaced with a second engaging portion 9h. The upper part of the second engaging portion 9h connects to the lower surface of the bottom wall 9a on the radially outer side of the insertion opening 9d, extends downward from there, and then extends radially outward. The lower part of the second engaging portion 9h extends downward from the radially outward extending portion of the upper part, and its inner circumferential surface is provided with a portion that protrudes radially inward, forming an inward claw shape. Here, the lower part of the second engaging portion 9h is located on the radially outer side of the cylindrical portion 6a as shown in the figure.

[0051] The inner tray 9C is an inner tray for back filling. When filling the cartridge 7 using the inner tray 9C with contents, as shown in Figure 15, the inner tray 9C is inserted into the cartridge body 8, and the engaging part 8g on the cartridge body side and the engaging part 9f on the inner tray side are engaged. Then, the cover 10 is fitted onto the cartridge body 8, and the cartridge 7 is displaced in an inverted position so that the cover 10 is positioned downwards, as shown in the figure. Then, the filling nozzle N is brought close to the inverted cartridge 7 from above and inserted into the insertion opening 9d, and the molten contents are discharged from the filling nozzle N into the internal space partitioned by the cover 10 and the upper outer peripheral wall 8a. After that, by solidifying the contents filled in the internal space, rod-shaped contents can be provided inside the cartridge 7.

[0052] Although one embodiment of the present invention has been described above, the present invention is not limited to such specific embodiments, and unless otherwise specifically limited in the above description, various modifications and changes are possible within the scope of the spirit of the present invention as described in the claims. For example, the configurations of the embodiments described above can be added or deleted as appropriate, and the configuration of one embodiment can be provided in other embodiments. Furthermore, the effects in the embodiments described above are merely illustrative of the effects that may arise from the present invention, and do not mean that the effects of the present invention are limited to the effects described above.

[0053] For example, in the embodiment described above, the weakening portion 8h provided on the cartridge body 8 is connected to the cartridge body side engaging portion 8g, but the weakening portion may be provided on the inner tray 9A and this weakening portion may be connected to the inner tray side engaging portion 9f. Also, in the embodiment described above, the cartridge body 8 is provided with a claw portion 8k and the base body 3 is provided with a hole portion 3d, but the cartridge body 8 may be provided with a hole portion and the base body 3 may be provided with a claw portion.
