Further, in the present specification, the vertical direction means the direction along the axis O of the case body 10, the upper direction means the direction in which the solid content 2 is fed out, the lower direction means the opposite direction, and the circumferential direction means the opposite direction. The first circumferential direction means one side of the circumferential direction, the second circumferential direction means the other side of the circumferential direction, and the radial direction means the direction along a straight line orthogonal to the axis O. However, the vertical cross section means a cross section including the axis O.

The feeding container 1 according to the first embodiment of the present invention shown in FIG. 1 has a case body 10. The case body 10 has a cylindrical shape extending along the axis O, and the upper end thereof is a feeding port 10a. In the present embodiment, the feeding port 10a is inclined obliquely with respect to the plane perpendicular to the axis O, but may be perpendicular to the axis O.

The case body 10 can store the solid content 2 inside. As the solid content 2, for example, a lipstick, lip balm, cosmetics such as stick eye shadow, chemicals, stick glue, or the like that can be applied to an object to be applied can be adopted. In this embodiment, the solid content 2 is a substantially columnar lipstick. The solid content 2 means a content having a hardness sufficient to retain its shape, and includes a content having a certain degree of softness such as a semi-kneaded material. The solid contents stored in the case body 10 are exposed to the outside of the case body 10 at the feeding port 10a.

An overcap 3 that covers the feeding port 10a may be detachably attached to the case body 10. In the present embodiment, the overcap 3 has an eclipsed cylindrical shape including a peripheral wall portion 3a and a top wall portion 3b, and is configured to cover a predetermined range from the upper end including the feeding port 10a of the case body 10. ing. When attached to the case body 10, there is a vertical gap between the top wall portion 3b of the overcap 3 and the feeding port 10a, and the solid content 2 slightly protrudes from the feeding port 10a. Also, the overcap 3 can be attached to the case body 10 without touching the top wall portion 3b with the solid content 2, and the protruding portion of the solid content 2 can be protected.

As shown in FIGS. 1 and 2, inside the case body 10, the feeding member 11 is arranged so as to be movable in the vertical direction while being stopped from rotating. The feeding member 11 can slide in the vertical direction with respect to the inner peripheral surface of the case body 10.

The feeding member 11 includes a cylindrical peripheral wall portion 11a and an elastic valve 11b integrally provided at the upper end of the peripheral wall portion 11a, and is provided on the outer peripheral surface of the peripheral wall portion 11a with respect to the inner peripheral surface of the case body 10. It is slidable. Further, a pair of rib-shaped guide rail portions 10b extending in the vertical direction are provided on the inner peripheral surface of the case body 10, and the feeding member 11 is a groove extending in the vertical direction provided on the outer peripheral surface of the peripheral wall portion 11a. A pair of guided portions 11c are engaged with the corresponding guide rail portions 10b and guided in the vertical direction, so that the case body 10 is prevented from rotating in the vertical direction with respect to the inner peripheral surface of the case body 10. It is slidable.

The elastic valve 11b is a so-called slit valve that has a disk shape centered on the axis O and has a cross-shaped slit 11d extending in the radial direction from the axis O at the center thereof. The slit 11d may have a Y-shape, a single-character shape, or another shape as long as it extends in the radial direction from the central portion.

The feeding member 11 can be obtained by integral molding such as injection molding using a soft synthetic resin such as rubber, elastomer, or polyethylene as a material. It is also possible to form the feeding member 11 by assembling a plurality of members.

The solid content 2 is housed in the case body 10 between the feeding port 10a and the elastic valve 11b of the feeding member 11, and the bottom portion thereof is supported on the upper surface of the elastic valve 11b. By raising the feeding member 11 from the position shown in FIG. 1, the solid content 2 housed inside the case body 10 can be pushed up and fed out from the feeding port 10a.

As shown in FIG. 1, a cylindrical shaft member 12 centered on the axis O is arranged below the feeding member 11. The shaft member 12 is vertically prevented from coming off by fitting to the peripheral wall portion 11a of the feeding member 11 at the upper end portion having an outer peripheral surface facing the inner peripheral surface of the peripheral wall portion 11a of the feeding member 11. Further, the shaft member 12 has a flange portion 12a having an upper surface facing the lower end surface of the peripheral wall portion 11a, and the shaft member 12 is a pair of covers extending in the vertical direction provided on the outer peripheral surface of the flange portion 12a. By engaging the guide grooves 12b with the corresponding guide rail portions 10b and guiding them in the vertical direction, the guide grooves 12b can slide in the vertical direction with respect to the inner peripheral surface of the case body 10 in a non-rotating state. ing.

Instead of providing the flange portion 12a on the shaft member 12, the shaft member 12 is prevented from rotating to the feeding member 11 by connecting the shaft member 12 to the feeding member 11 via a spline portion. The member 12 may be arranged so as to be movable in the vertical direction integrally with the feeding member 11 in a state where the member 12 is prevented from rotating with respect to the case body 10.

A male screw 12c is provided on the outer peripheral surface of the shaft member 12 in a portion below the flange portion 12a over substantially the entire length. The male screw 12c is screw-coupled to a screw portion 40a provided on the operating member 13 described later. A pair of outwardly facing engaging claws 12d are provided at the lower end of the shaft member 12 at intervals in the circumferential direction, which makes it difficult for the shaft member 12 to come out upward from the screw portion 40a. The outer peripheral surface of each engaging claw portion 12d is inclined inward in the radial direction toward the lower end, and is elastically deformable inward in the radial direction. Therefore, the lower end portion of the shaft member 12 is easily inserted inside the screw portion 40a in the radial direction.

As shown in FIG. 1, the operating member 13 is connected to the case body 10 so as to be relatively rotatable in the circumferential direction. The operating member 13 has an annular grip portion 13a arranged coaxially with the case body 10 below the case body 10. The grip portion 13a has a double cylindrical shape having the same outer diameter as the case body 10.

In the present embodiment, the operating member 13 has a cylindrical engaging cylinder portion 13b protruding from the upper end of the grip portion 13a toward the inside of the case body 10, and is provided from the outer peripheral surface of the engaging cylinder portion 13b. The annular locking projection 13c provided so as to project outward in the radial direction is locked to the annular locking groove 10c provided on the inner peripheral surface of the case body 10, thereby surrounding the case body 10. It is held so that it can rotate relative to the direction.

In the state before the solid content 2 shown in FIG. 1 is unwound, the lower end portion of the shaft member 12 is located inside the grip portion 13a.

A ratchet mechanism portion 20 is provided on the radial outer side of the shaft member 12 below the feeding member 11. The ratchet mechanism unit 20 operates so as to allow the relative rotation of the operating member 13 with respect to the case body 10 in the first circumferential direction and prevent it in the second circumferential direction.

As shown in FIGS. 1 and 4, in the present embodiment, the ratchet mechanism portion 20 includes a pair of claw portions 21 provided on the side of the operating member 13 and a gear portion 22 provided on the side of the case body 10. have. Here, FIG. 4 shows a cross section taken along the line AA of FIG. 1, FIG. 5 shows a cross section taken along the line BB of FIG. 1, and FIG. 6 shows a cross section taken along the line CC of FIG. ing. In addition, in FIG. 4, FIG. 5, and FIG. 6, the shaft member 12 is shown by a two-dot chain line.

As shown in FIGS. 1, 3 and 4, the pair of claw portions 21 are supported by the leg portions 21a protruding from the upper end of the engaging cylinder portion 13b of the operating member 13, and the legs, respectively. A curved piece 21b extending in the circumferential direction from the portion 21a and a claw piece 21c extending radially outward from the tip of the curved piece 21b are integrally provided. The surface of each claw piece 21c facing away from the curved piece 21b is perpendicular to the circumferential direction. Each of the pair of claw portions 21 is elastically deformed in a direction in which the curved piece 21b uses the leg portion 21a as a fulcrum to increase the degree of curvature, so that the claw pieces 21c are radially both sides between the shaft member 12 and the case body 10. It can be elastically deformed so as to be displaced to.

On the other hand, as shown in FIG. 4, the gear portions 22 are integrally provided on a plurality (8) locking surfaces 22a integrally provided on the inner peripheral surface of the case body 10 and integrally on the inner peripheral surface of the case body 10. It has a plurality of (eight) riding surfaces 22b and the like. Each locking surface 22a engages with the claw piece 21c to lock the claw portion 21 when the operating member 13 rotates relative to the case body 10 in the second circumferential direction, whereby the operating member 13 It is configured to prevent the relative rotation of the case body 10 in the second circumferential direction. Each riding surface 22b curves and extends between two adjacent locking surfaces 22a from the radial outer portion of one locking surface 22a toward the radial inner portion of the other locking surface 22a. When the operating member 13 rotates relative to the case body 10 in the first circumferential direction, the case body of the operating member 13 is guided by guiding the claw piece 21c of the claw portion 21 so as to get over the locking surface 22a. It is configured to allow relative rotation in the first circumferential direction with respect to 10.

The number of the claw portion 21 and the locking surface 22a to the riding surface 22b provided on the ratchet mechanism portion 20 can be variously changed.

As shown in FIG. 1, the feeding container 1 of the present embodiment provides a sliding resistance between the operating member 13 and the case body 10 when the operating member 13 rotates relative to the case body 10 in the circumferential direction. It can be configured to include the sliding resistance imparting portion 30 to be imparted. As shown in FIG. 3, the sliding resistance applying portion 30 is integrally provided with the operating member 13. The sliding resistance applying portion 30 elastically contacts the inner peripheral surface of the case body 10 at the portion between the screw portion 40a and the ratchet mechanism portion 20, so that the operating member 13 is in the circumferential direction with respect to the case body 10. It is configured to impart sliding resistance between the operating member 13 and the case body 10 when it is relatively rotated.

As shown in FIGS. 1, 3 and 5, the sliding resistance applying portion 30 of the present embodiment includes a pair of pillar portions 31, a support 32, four elastic pieces 33, and four sliding protrusions 34. It is said that it has a structure.

More specifically, each of the pair of pillar portions 31 projects from the upper end of the engaging cylinder portion 13b between the shaft member 12 and the case body 10, and also functions as a pair of leg portions 21a. The pillar portion 31 and the leg portion 21a may be provided separately. The upper ends of the pair of pillars 31 are integrally connected to the support 32 located above the claws 21.

The support 32 has a cylindrical shape coaxial with the engaging cylinder portion 13b, and is arranged between the shaft member 12 and the case body 10.

Each of the four elastic pieces 33 has an elongated plate shape, and is provided at the upper end of the support 32 so as to be integrally connected at equal intervals in the circumferential direction. As shown in FIG. 3, each elastic piece 33 extends upward from the support 32 and can be elastically deformed inward in the radial direction with the support 32 as a fulcrum. The distance between the four elastic pieces 33 in the circumferential direction does not have to be equal. Further, the number of elastic pieces 33 can be variously changed.

The pillar portion 31, the support body 32, and the elastic piece 33 are arranged at intervals with respect to the inner peripheral surface of the case body 10, respectively.

The four sliding protrusions 34 are integrally provided on a surface facing the outside of the tip (upper end) of the corresponding elastic piece 33, and each protrudes radially outward from the surface. As shown in FIG. 1, each of the sliding protrusions 34 is in contact with the inner peripheral surface of the case body 10 in a state where the elastic piece 33 is elastically deformed inward in the radial direction with the support 32 as a fulcrum. .. In this way, the sliding protrusion 34 is elastically in contact with the inner peripheral surface of the case body 10, whereby when the operating member 13 rotates relative to the case body 10 in the circumferential direction, the operating member 13 A sliding resistance is provided between the case body 10 and the case body 10. The sliding resistance imparted by the sliding resistance imparting portion 30 between the operating member 13 and the case body 10 is subjected to an experiment or the like in advance in consideration of operability when the solid content 2 is fed out from the case body 10. It can be set to an appropriate value.

As shown in FIGS. 1 and 3, the operating member 13 has a screw portion 40a formed as a female screw that is screw-coupled to the male screw 12c of the shaft member 12.

As shown in FIGS. 1, 3 and 6, in the present embodiment, the screw portion 40a is integrally provided on the inner peripheral surface of the screw portion 40 integrally provided at the upper end portion of the operating member 13. .. The screwed portion 40 is configured to include four upper pillar portions 41, an upper support 42, four projecting pieces 43, and four convex portions 44. The screwing portion 40 is located between the ratchet mechanism portion 20 and the feeding member 11.

More specifically, the four upper pillar portions 41 extend upward from the support 32 between the shaft member 12 and the case body 10. The upper end of the upper pillar portion 41 is integrally connected to the upper support 42 located above the elastic piece 33. The four upper column portions 41 are arranged between two elastic pieces 33 adjacent to each other in the circumferential direction. That is, the four upper pillar portions 41 are evenly arranged in the circumferential direction. The number and arrangement of the upper pillar portions 41 can be variously changed according to the number and arrangement of the elastic pieces 33.

The upper support 42 has a cylindrical shape coaxial with the support 32. The upper support 42 is arranged between the shaft member 12 and the case body 10.

Each of the four projecting pieces 43 has a plate shape, and is provided at the upper end of the upper support 42 so as to be integrally connected at equal intervals in the circumferential direction. As shown in FIG. 3, each projecting piece 43 extends upward from the upper support 42, and is elastically deformable on both sides in the radial direction with the upper support 42 as a fulcrum. With such a configuration, when the shaft member 12 is inserted inside the screw portion 40a in the radial direction, the projecting piece 43 elastically deforms outward in the radial direction so as to expand the diameter of the screw portion 40a, so that the male screw of the shaft member 12 The 12c can be inserted all the way at once by overcoming the screw portion 40a. That is, the shaft member 12 and the screw portion 40a can be assembled by a simple operation of simply sliding the shaft member 12 downward relative to the screw portion 40a without rotating the shaft member 12 with respect to the screw portion 40a. .. Further, when the operating member 13 is formed, the projecting piece 43 is elastically deformed outward in the radial direction, so that the projection piece 43 is detached from the screw portion 40a along the axis O without rotating the mold corresponding to the screw portion 40a. Since it can be forced (that is, pulled out), the operating member 13 can be easily formed.

A screw portion 40a is provided on the inner peripheral surface of each projecting piece 43. In the present embodiment, the screw portion 40a is provided only on a part of the upper side of the projecting piece 43.

The convex portion 44 projects radially outward from the outer peripheral surface of each projecting piece 43. The convex portion 44 is configured to be slidable on the inner peripheral surface of the case body 10. As a result, the bond strength of the threaded bond between the threaded portion 40a and the male thread 12c can be increased, and the threaded bond is less likely to come off. The convex portion 44 is not an essential configuration. That is, the outer peripheral surface of the projecting piece 43 and the inner peripheral surface of the case body 10 are brought into contact with each other to suppress the deformation of the projecting piece 43 in the radial direction, and the screw portion 40a and the male screw 12c are screwed together with high strength. For example, a convex portion may be provided on the inner peripheral surface of the case body 10, or no convex portion may be provided on either the outer peripheral surface of the projecting piece 43 or the inner peripheral surface of the case body 10. You may.

The upper pillar portion 41, the upper support 42, and the four projecting pieces 43 are arranged at intervals with respect to the inner peripheral surface of the case body 10, respectively.

In the present embodiment, the overcap 3, the case body 10, the shaft member 12, and the operating member 13 are integrally formed by injection molding of a synthetic resin material, respectively.

As shown in FIG. 1, the feeding container 1 extends through the inside of the shaft member 12 to the bottom surface of the elastic valve 11b, and a hollow rod-shaped filling nozzle 16 described later can be inserted in order to penetrate the elastic valve 11b from the bottom surface side. It has a nozzle insertion path 14.

In the present embodiment, the nozzle insertion path 14 extends through the inside of the operating member 13 and the shaft member 12 to the bottom surface of the elastic valve 11b. That is, the nozzle insertion path 14 is partitioned by the inner peripheral surface of the operating member 13, the inner peripheral surface of the shaft member 12, and the bottom surface of the elastic valve 11b.

Further, in the present embodiment, the lower end of the nozzle insertion path 14 is closed by the label 15 by attaching a circular label 15 to the bottom surface of the grip portion 13a of the operating member 13.

As shown in FIG. 7, the feeding container 1 of the present embodiment having the above configuration has the overcap 3 removed from the case body 10, and the case body 10 is held by one hand or the like while being held by the other hand or the like. By gripping the gripping portion 13a of the operating member 13 and rotating it in the first circumferential direction, the operating member 13 is rotated relative to the case body 10 in the first circumferential direction, whereby the solid content 2 is placed in the case. It can be fed out from the feeding port 10a of the body 10.

That is, when the operating member 13 is rotated relative to the case body 10 in the first circumferential direction, the screw portion 40a, which is a part of the operating member 13, rotates relative to the case body 10 in the first circumferential direction. Since the shaft member 12 provided with the male screw 12c screwed to the screw portion 40a is stopped by the case body 10, when the operating member 13 is rotated relative to the case body 10 in the first circumferential direction, the screw portion is formed. Due to the screwing action of the 40a and the male screw 12c, the shaft member 12 rises integrally with the feeding member 11 with respect to the case body 10. As a result, the solid content 2 is pushed up by the ascending feeding member 11, and is fed out from the feeding port 10a to the outside of the case body 10. The amount of extension (protrusion amount) of the solid content 2 from the case body 10 can be adjusted by the amount of relative rotation of the operating member 13. Therefore, by rotating the operating member 13 relative to the case body 10 by a desired amount in the first circumferential direction, a desired amount of the solid content 2 is fed out from the feeding port 10a of the case body 10 and used. be able to.

On the other hand, when the operating member 13 is relatively rotated with respect to the case body 10 in the second circumferential direction opposite to the time when the solid content 2 is unwound, the ratchet mechanism 20 prevents the relative rotation. Therefore, even if the operating member 13 is unexpectedly operated in the direction of relative rotation with respect to the case body 10 in the second circumferential direction, the feeding member 11 supporting the lower end portion of the solid content 2 does not descend, and this This prevents the solid content 2 from being carried into the case body 10. Therefore, even when the solid content 2 having a hardness that is difficult to carry into the case body 10, such as a relatively soft lipstick, is stored, the operating member 13 suddenly makes a second with respect to the case body 10. It is possible to prevent the solid content 2 from being damaged such as losing its shape or breaking by being operated so as to rotate relative to the circumferential direction.

As shown in FIGS. 8 to 11, the feeding container 1 configured as described above can be back-filled in which the solid content 2 is filled from the bottom surface side of the feeding member 11. Back filling can be performed, for example, as follows.

First, the case body 10, the feeding member 11, the shaft member 12, and the operating member 13 are assembled so as to be in the state shown in FIG. Then, a cylindrical capsule 17 having one end closed is attached to the feeding port 10a. The capsule 17 has a cylindrical tubular wall 17a that is in close contact with the outer peripheral surface of the case body 10 at the feeding port 10a, and an end wall 17b that closes one end of the tubular wall 17a. A vertical groove 17c extending from the other end of the cylinder wall 17a toward one end is provided at one location on the inner peripheral surface of the cylinder wall 17a in the circumferential direction so that the capsule 17 can be easily removed from the feeding port 10a. There is. The end wall 17b has an inner surface that follows the shape of the tip to be given to the solid content 2.

Next, the cylindrical filling nozzle 16 is inserted into the feeding container 1 in an inverted posture with the feeding port 10a facing vertically downward. At this time, in the filling nozzle 16, the tip portion 16a is coaxial with the axis O and the tip portion 16a of the grip portion 13a is arranged in a state where the tip portion 16a capable of discharging the solid content 2 which is heated and has fluidity is arranged vertically downward. It is inserted into the nozzle insertion path 14 from the bottom surface, and the slit 11d of the elastic valve 11b is pushed open by the tip portion 16a. Then, as shown in FIG. 8, the solid content 2 is discharged with the tip portion 16a located between the elastic valve 11b and the feeding port 10a. At this time, as the solid content 2 is filled inside the case body 10, the air inside the case body 10 is between the slit 11d opened as shown in FIG. 9 and the outer peripheral surface of the filling nozzle 16. It is smoothly discharged through the gap G formed in the.

When the filling of the solid content 2 is completed, the filling nozzle 16 is pulled out from the elastic valve 11b as shown in FIG. At this time, the filling space between the elastic valve 11b and the feeding port 10a may not be completely filled with the solid content 2, and even in such a case, the feeding member 11 may be used after the solid content 2 is solidified. There is no problem in feeding out and using the solid content 2. The solid content 2 solidifies as it cools, and the tip of the solid content 2 is formed in a shape along the inner surface of the end wall 17b of the capsule 17.

When the filling nozzle 16 is pulled out from the feeding container 1, the feeding container 1 is turned upside down to be in an upright posture, the capsule 17 is removed from the feeding port 10a, and the overcap 3 is attached so as to cover the feeding port 10a. ..

As a result, the feeding container 1 provided with the ratchet mechanism portion 20 can be miniaturized, and the manufacturing cost thereof can be reduced.

Further, in the feeding container 1 of the present embodiment, since the operating member 13 has an inner peripheral surface provided with the screw portion 40a, the nozzle insertion path 14 can be efficiently provided inside the feeding container 1. Therefore, the outer diameter of the feeding container 1 can be reduced and the size can be reduced.

Further, in the feeding container 1 of the present embodiment, since the screw portion 40a is provided at the upper end portion of the operating member 13, the vertical movement distance of the shaft member 12 due to the screwing action can be efficiently obtained. Therefore, the height of the feeding container 1 can be reduced and the size can be reduced.

Also, when the solid content 2 is filled, the air in the filling space can be easily discharged through the gap G between the pushed-open slit 11d and the filling nozzle 16.

In the first embodiment described above, the feeding member 11 including the elastic valve 11b is fitted and attached to the shaft member 12, but as in the first modification shown in FIG. 12, the feeding member 11 and the feeding member 11 are attached. The shaft member 12 may be integrally formed by insert molding or two-color molding. In the example shown in FIG. 12, in order to increase the coupling strength between the feeding member 11 and the shaft member 12, the shaft member 12 has a plurality of through holes 12e provided at intervals in the circumferential direction, and the feeding member 12 has a plurality of through holes 12e. 11 has a protruding portion 11e arranged in each of the plurality of through holes 12e.

Further, in the first embodiment described above, the elastic valve 11b is provided with a slit 11d so that the elastic valve 11b can be rolled up toward the filling space when pushed by the tip portion 16a of the filling nozzle 16. It is preferable that the elastic valve 11b is easily rolled up on the side of the filling space and is hard to be rolled up on the side of the nozzle insertion path 14. Therefore, the elastic valve 11b may be configured as in the second modification shown in FIGS. 13 to 15, for example.

As shown in FIG. 13, in this modification, the elastic valve 11b is provided with a slit 11d having a cross-shaped top view extending in the radial direction from the central portion 11h, and is pushed by the filling nozzle 16 to be rolled up toward the feeding port 10a. It has a movable portion 11f that opens a slit 11d, and the thickness T1 at the outer peripheral edge 11g of the movable portion 11f is thinner than the thickness T2 at the central portion 11h of the movable portion 11f, and the outer peripheral edge 11g of the movable portion 11f is thinner. , The movable portion 11f is arranged unevenly downward with respect to the central portion 11h.

In this modification, as described above, the outer peripheral edge 11g, which is the center of rotation of the movable portion 11f when the movable portion 11f is turned, is biased downward from the central portion 11h farthest from the center of rotation. .. Therefore, when the movable portion 11f is pushed from the bottom surface side by the filling nozzle 16, the interference between the portions divided by the slits 11d in the movable portion 11f at the central portion 11h is small, and as a result, as shown in FIG. The movable portion 11f can be easily rolled up toward the filling space and easily passed through the filling nozzle 16.

Further, when the movable portion 11f is pushed from the upper surface side by the solid content 2 after the solid content 2 is filled, the portions divided by the slit 11d in the movable portion 11f have a large interference generated in the central portion 11h. As a result, as shown in FIG. 15, the movable portion 11f is unlikely to be rolled up toward the nozzle insertion path 14. Therefore, it is possible to prevent the solid content 2 from leaking from the slit 11d to the nozzle insertion path 14 side after the solid content 2 is filled.

Further, in this modification, as described above, the thickness T1 at the outer peripheral edge 11g of the movable portion 11f is thinner than the thickness T2 at the central portion 11h of the movable portion 11f, whereby the elastic valve 11b becomes thinner. The side of the filling space makes it easier to turn, and the side of the nozzle insertion path 14 makes it harder to turn. The thickness T1 at the outer peripheral edge 11g of the movable portion 11f may be set to the thickness T2 or more at the central portion 11h of the movable portion 11f.

Also in the present embodiment, as in the case of the first embodiment, the tip portion 16a of the filling nozzle 16 is inserted into the nozzle insertion path 14 from the bottom surface side of the grip portion 13a, and the sharp tip of the filling nozzle 16 is an elastic valve. It is abutted against 11b from the bottom surface side. As a result, the puncture hole 11i is formed in the elastic valve 11b, and the tip portion 16a of the filling nozzle 16 expands the puncture hole 11i to penetrate the elastic valve 11b and is arranged in the filling space.

Then, as shown in FIG. 18, the solid content 2 is discharged from the discharge port 16b, and the filling space is filled with the solid content 2. As shown in FIG. 18, the filling machine provided with the filling nozzle 16 is a syringe type, but the filling machine is not limited to this. When the filling of the solid content 2 is completed, as shown in FIG. 19, the filling nozzle 16 is pulled out from the elastic valve 11b, and the puncture hole 11i of the elastic valve 11b is closed by the elasticity of the elastic valve 11b. Subsequent steps are the same as in the case of the first embodiment.
