A side surface of the cap 8 is provided with an operating portion 64 movable in a radial direction where a locking rib is formed on an inner surface. A base of the nozzle 41 of the inner plug body 4 is provided with a locking protrusion that protrudes outward. When a force is applied from the outside to the operating section 64 of the cap 8, the locking rib reaches a position that causes interference with the locking protrusion of the nozzle 41 in the radial direction, and then, in a state where the locking protrusion and the locking rib interfere with each other, rotating the cap 8 relative to the container body 3 enables the inner plug body 4 to be removed together with the cap 8 from the mouth portion 2 of the container body 3.SELECTED DRAWING: Figure 1

Description

The present invention relates to a capped container that allows the contents to be used up to the last drop, and an inner plug that can be engaged with the container body of the container.

In recent years, awareness of the Sustainable Development Goals (SDGs) for creating a sustainable society has increased dramatically, and in the cosmetics industry, containers that allow you to use up the contents are attracting attention.

For example, Patent Document 1 proposes a configuration in which a plug is detachably fitted to the wide-mouthed opening of a tube container, allowing any cosmetic remaining in the tube to be used up to the very last drop by removing the plug.

JP 2003-104403 A

However, in the configuration of Patent Document 1, when the contents become low, the stopper is detached separately from the container opening, so when removing the stopper, there is a risk that the contents adhering to the stopper may soil the user's hands or the surface on which the stopper is placed, such as a washbasin or desk.

In view of the above, the present invention aims to provide a container that allows the contents to be used up to the last drop and that allows the inner stopper to be removed without soiling the hands or the storage area.

In order to solve the above problems, in one aspect of the present invention,
A container with a cap,
The container includes a container body having a storage section for storing contents and a mouth section that is closely attached to an upper end of the storage section;
a nozzle protruding upward and a mounting portion located below the nozzle and engaging with the mouth portion; and an inner plug body covering an upper end of the mouth portion,
The cap has an operating part on its side that is movable in the radial direction and has a locking rib formed on its inner surface,
A locking projection is provided at a base of the nozzle of the inner plug, the locking projection projecting outward.
When a force is applied from the outside to the operating portion of the cap, the locking rib reaches a position where it interferes with the locking protrusion of the nozzle in the radial direction,
The inner plug body can be removed from the mouth of the container body together with the cap by rotating the cap relative to the container body in a state in which the locking projection and the locking rib interfere with each other.
A container with a cap is provided.

In one embodiment of the container, the contents can be used up to the last drop, and the inner plug can be removed without soiling the hands or the surface where it is placed.

Below, a description will be given of an embodiment of the present invention with reference to the drawings. In the following drawings, the same components are given the same reference numerals, and duplicated explanations may be omitted.

The present invention relates to a container, an inner stopper, and a container with a cap. The container is, for example, a flexible tube container made of resin, metal film, paper, or the like. Alternatively, the container may be a self-supporting container.

The contents to be stored in the container of the present invention are preferably viscous substances that are to be used in several portions, rather than cosmetics, toothpaste, seasonings, and other single-use items. In this specification, viscous substances refer to viscous cosmetics, viscous medicines, viscous soaps, and the like, such as beauty serums, creams, hair wax, ointments, and toothpastes, which have viscosity.

First Embodiment
First, the configuration of a container according to a first embodiment of the present disclosure will be described with reference to Figures 1 to 4. Figure 1 is an exploded view of a capped container according to an embodiment of the present disclosure. Figure 2 is an enlarged cross-sectional view of a cross section of surface A in Figure 1, passing through an inner cap operating section near the mouth of a capped container according to an embodiment before disassembly. Figure 3 is an enlarged cross-sectional view of a cross section of surface B in Figure 1, passing through an inner cap lower tube near the mouth of a capped container according to an embodiment before disassembly. Figure 4 is an explanatory exploded view of an outer cap, an inner cap, and an inner stopper according to an embodiment.

Referring to Figures 1 and 2, the capped container 10 has a container 5 and a cap 8. The container (tube container) 5 has a storage section 1, a mouth section 2, and an inner plug body 4. The cap 8 has an inner cap 6 and an outer cap 7.

The container 1 contains the contents. The container 1 is, for example, a flexible container such as a tube. The mouth 2 is a wide-mouthed cylindrical ring that is tightly attached to the upper end of the container. During the distribution process after manufacture, the container 1 and the mouth (mouth member) 2 are in tight contact with each other, and the container 1 and the mouth 2 become the container body (tube container body) 3.

In this example, the storage section 1 is a tube, and in the state shown in FIG. 1, from the top, has a tube shoulder section 11, a body section 12, and a tail section 13.

When the storage section 1 is a tube, the storage section 1 is formed from a material that is soft and flexible, such as a thin resin film, a metal film (e.g., aluminum), a laminated film of a resin film and a metal film, a film in which an inorganic substance is vapor-deposited onto a resin film, synthetic rubber, paper, etc.

The storage unit 1 is not limited to a tube with a linearly closed tail 13, but may be, for example, a flexible container with a bottom, such as a cylindrical or prismatic outer shape, such as a pouch container. Alternatively, the storage unit 1 may be a double container in which a flexible inner bag is housed in a rigid container.

The mouth 2 is a cylindrical mouth member with a hole 20 formed in the center, with the upper part being the mouth tube part 21 and the lower part being the ring side shoulder part 22. A helical protrusion (screw protrusion, screw protrusion) 23 is provided on the inner peripheral surface of the mouth tube part 21.

The mouth 2 is formed, for example, from a resin that is more rigid than the container 1. The hole 20 of the wide-mouthed mouth 2 has an inner diameter large enough for a user to insert a finger and wipe off the contents.

As shown in Figures 2 and 3, the tube shoulder 11 is attached in close contact with the outside of the ring side shoulder 22 located at the bottom of the mouth 2 by insert molding, heat welding, adhesives, etc. This ensures that the container 1 and the mouth 2 are in close contact with each other, resulting in a container body 3 that cannot be separated even when the inner stopper 4 is removed.

The inner plug (nozzle inner plug) 4 is a plug member with a nozzle 41 formed on the upper side and an attachment part 45 formed on the lower side. The nozzle 41 protrudes upward, and a small hole 40 is formed at the apex through which the contents are squeezed out.

The nozzle 41 is made up of a thin nozzle 41N with a small diameter at the top, a central nozzle 41M with a larger diameter than the thin nozzle 41N at the center, and a wide nozzle 41K at the base of the bottom end. An annular fitting protrusion 42 is formed on the outer periphery of the thin nozzle 41N at the top.

Referring to Figures 2 to 4, an annular sloped piece 43 is provided on the upper surface of the central nozzle 41M so as to surround the lower end of the thin nozzle 41N. The upper surface of the annular sloped piece 43 has a wavy shape that alternates between a continuous upper end crest (peak) 431 and a lower end valley (valley) 433. A number of locking projections 44a, 44b are provided on the outer circumferential surface of the wide nozzle 41K on the base side.

In addition, the mounting portion 45 of the inner plug 4 in this embodiment has an annular closure plate 46 that extends outward from the lower end of the nozzle 41, and a tubular portion 47 that hangs down slightly inward from the edge of the lower surface of the annular closure plate 46. In addition, a helical protrusion (screw protrusion, screw protrusion) 48 is provided on the outer peripheral surface of the tubular portion 47.

As shown in Figures 2 and 3, the container 5, which is a tube container, can be engaged with a cap 8. The cap 8 has an inner cap 6 and an outer cap 7. For the sake of explanation, in Figure 4, the inner cap 6 and the outer cap 7 are shown facing in the same direction, but the center plug 4 is shown at a slightly different angle from the cap 8.

The outer cap 7 has a cylindrical shape with a top and has an outer top surface 71 and a peripheral wall 72 which is a side surface. Also, referring to FIG. 4, the outer peripheral wall 72 has a thick peripheral wall 72U on the upper side and a thin peripheral wall 72L on the lower side which is thinner on the inside than the thick peripheral wall 72U, thereby forming a peripheral wall step portion 73. A rectangular notch 74 is formed in the thin peripheral wall 72L from the lower end upward. Also, a groove-shaped vertical slit 75 is formed in the thick peripheral wall 72U from the peripheral wall step portion 73 at the lower end upward, and a horizontal slit 76 which is thinner than the vertical slit 75 is formed so as to cross the vertical slit 75.

The inner cap 6 is a cap-side engagement member that is fitted inside the outer cap 7. The inner cap 6 has an inner top surface 61, an upper tube 62, a lower tube 63, an operating part 64, and an engagement tube (inner tube) 65. A stoppering protrusion 66 is formed in the center of the underside of the inner top surface 61.

The outer tube of the inner cap 6 has an upper tube 62 on the top and a lower tube divided by a slit 60, with lower tubes 63 (63a, 63b) and operating parts 64 (64a, 64b) arranged alternately. The boundary between the lower tube 63 and the operating parts 64 is divided by the slit 60. The upper tube 62 is an area located inside the thick peripheral wall 72U when engaged with the outer cap 7. The lower tube 63 has a larger diameter than the upper tube 62, and is an area located inside the thin peripheral wall 72L when engaged with the outer cap 7. The operating part (button part) 64 has a larger diameter than the lower tube 63, and is an area that protrudes from the cutout 74 to the outer periphery when engaged with the outer cap 7.

As shown in FIG. 4, two vertically extending tube ribs (631a, 632a), (631b, 632b) are formed on the inner circumferential surface of each of the two lower tubes 63a, 63b. In addition, two vertically extending locking ribs (641a, 642a), (641b, 642b) are formed on the inner circumferential surface of each of the two operating parts 64a, 64b.

In the cap-engaged state, the locking ribs (641a, 642a), (641b, 642b) of the operating part 64 are positioned to face the locking protrusions 44a, 44b in the up-down direction as shown in FIG. 2, and in the non-operated state, the locking ribs (641a, 642a), (641b, 642b) are positioned radially outward from the locking protrusions 44a, 44b. Therefore, when the operating part 64 is in the non-operated state where it is not pressed, none of the locking ribs 641a, 642a, 641b, 642b interferes with the locking protrusions 44a, 44b.

In addition, in the cap engagement state, as shown in FIG. 3, the lower ends of the tube ribs 631b, 632b of the lower tube 63b are located above the locking projections 44a, 44b. Similarly, the lower ends of the tube ribs 631a, 632a of the lower tube 63a (see FIG. 6) are located above the locking projections 44a, 44b. Therefore, there is no interference between the tube ribs (631a, 632a), (631b, 632b) of the lower tube 63 and the locking projections 44a, 44b at any time.

Furthermore, referring to FIG. 4, a peripheral vertical rib 621 is formed on the outer peripheral surface of the upper tube 62 so as to rise from the top surface of the lower tube 63. A peripheral horizontal rib 622 that is shorter and thinner than the peripheral vertical rib 621 is provided so as to cross the peripheral vertical rib 621.

When the outer cap 7 and the inner cap 6 are engaged to form the cap 8, the outer peripheral vertical rib 621 of the inner cap 6 fits into the vertical slit 75 of the outer cap 7. At this time, the outer peripheral horizontal rib 622 fits into the horizontal slit 76. Due to this engagement, after the cap 8 is assembled, the outer cap 7 and the inner cap 6 are restricted from rotating relative to each other and are fixed so that they do not fall out in the vertical direction.

As shown in Figs. 2 to 4, an annular inner peripheral fitting protrusion 67 is formed on the inner peripheral surface of the inner tube, the engagement tube 65, and the lower end of the engagement tube 65 is a wavy bent lower end 68. When the cap 8 is engaged with the container 5, the wavy bent lower end 68 of the engagement tube 65 slides down the upper surface of the annular slope piece 43 and engages so as to fit in. Details of the engagement will be described later with reference to Fig. 6. As shown in Fig. 2, it is preferable that the wavy bent lower end 68 is inclined so that it extends further on the outer peripheral side than on the inner peripheral side.

Figure 5 is an explanatory diagram of the operation of attaching and removing the cap 8 to the container 5 of the embodiment. In the capped container 10 of the present disclosure, when attaching the cap 8, first, as shown in (1), the cap 8 is pushed into the container 5 without applying force to the operating portion 64 of the cap 8, so that the cap 8 engages with the nozzle 41 and roughly engages with the container 5.

In more detail, when the cap 8 is engaged with the container 5, when the cap 8 is pushed downward into the inner plug 4, the inner peripheral fitting protrusion (fitting portion) 67 of the engagement tube 65 of the cap 8 climbs over the outer peripheral fitting protrusion 42 (fitting portion) of the nozzle 41 and moves to the underside of the outer peripheral fitting protrusion 42, thereby riding up and fitting (snap-engagement).

When attaching the cap 8 to the container 5, if the cap 8 stops in a floating position when it is pushed down, rotate the cap 8 further relative to the container 5 as shown in attachment (2) in Figure 5.

Here, the details of the positioning (2) when attaching the cap in FIG. 5 will be explained using FIG. 5 and FIG. 6. FIG. 6 is an explanatory diagram of the operation when rotating the cap 8 relative to the container 5 when attaching the cap 8 of the embodiment. In FIG. 6, (d) is a cross-sectional view in the state (a), (e) is a cross-sectional view in the state (b), and (f) is a cross-sectional view in the state (c). Note that FIG. 6(a) to FIG. 6(c) show an excerpt of the middle plug 4 and the engaging tube 65 of the inner cap 6. Note that FIG. 6(d) to FIG. 6(f) correspond to the C-plane cross-sectional views of FIG. 2 and FIG. 3.

As shown in FIG. 5, the upper surface of the central nozzle 41M, which is the boundary between the steps of the multi-stage nozzle 41, is provided with a wavy annular slope piece 43 whose upper surface alternates between upper end peaks (peaks) 431 and lower end valleys 433 (valley bottoms). On the other hand, as shown in FIG. 4 and FIG. 6, the lower end of the engagement tube 65 of the cap 8 is a wavy bent lower end 68 that includes two wave shapes consisting of a continuous upper end valley (valley) 681 and a lower end peak (peak) 683.

When attaching the cap 8 to the container 5, the cap 8 is pushed into any position. If the cap is inserted into the position shown in FIG. 6(c), no rotation is required. However, if the cap is inserted into a position other than that shown in FIG. 6(c), a rotation, i.e., a positioning operation, is required after the insertion operation during installation.

Here, when the cap 8 is attached, the state where the cap 8 stops in a floating state corresponds to a state where the lower end crest 683 of the engagement tube 65 is not in a position to fit into the lower end valley 433 of the annular slope piece 43. For example, as shown in FIG. 6(a), when the lower end crest 683 of the wavy bent lower end 68 is located at the upper end crest 431 of the annular slope piece 43, even if the cap 8 is pushed in, the lower end of the peripheral wall 72 of the cap 8 is in a floating position relative to the upper surface of the annular closure plate 46 of the inner plug body 4. In this case, the user further rotates the cap 8. Also, in this state, the lower part of the cap 8 is in a state where the locking rib pair 641, 642 of the operating part 64 is not in a position to sandwich the locking protrusion 44 in the circumferential direction, as shown in FIG. 6(d).

As the rotation continues, as shown in Figure 6 (b), the inclined edge 682 of the wavy bent lower end 68 of the engagement tube 65 slides down the inclined upper surface 432 of the annular slope piece 43 of the nozzle 41.

As the rotation continues, the lower end crest 683 of the engagement tube 65 engages into the lower end valley 433 of the annular slope piece 43, and the upper end valley 681 engages into the upper end crest 431. At this time, as shown in Figure 6 (e) and Figure 6 (f), the lower part of the cap 8 is guided to a position where the locking rib pair 641, 642 of the operating part 64 sandwiches the locking protrusions 44a, 44b that connect with the outer circumferential surface of the wide nozzle 41K at the base of the nozzle 41 in the circumferential direction. By being guided to this position, the cap 8 becomes capable of rotating together with the inner plug 4 when the operating part 64 is pressed.

In the state shown in FIG. 6(c), the lower end of the outer peripheral wall 72 of the cap 8 is in contact with or close to the upper surface of the annular closure plate 46 of the inner plug 4, and the cap 8 is completely attached to the container 5.

As shown in FIG. 6, in this example, the wavy bent lower end 68 of the engagement tube 65 and the annular slope piece 43 of the nozzle 41 are shown as having two wave shapes composed of a continuous valley and a mountain, but the wavy bent lower end 68 and the annular slope piece 43 may be configured to have one or three or more wave shapes in the circumferential direction. The number of locking protrusions 44 may also be one or three or more, as long as there are more than one. When the wavy bent lower end 68 and the annular slope piece 43 are three or more wave shapes, the number of locking protrusions 44 at the lower end of the nozzle 41 may be three or more, which is the same number as the wave shapes, or the number of wave shapes and the number of locking protrusions may be different. Furthermore, in this example, the part that introduces the rotation is a wavy edge, but the lower end of the engagement tube 65 and the upper end of the annular slope piece 43 may be a jagged saw-like inclined edge formed by a linear slope. Alternatively, the lower end of the engagement tube 65 may not have the above-mentioned rotation introduction part and may be a straight plane.

On the other hand, when removing the cap 8 from the container 5, the cap 8 is pulled up against the container 5 as shown in FIG. 5 while grasping the peripheral wall 72 of the outer cap 7 other than the operating portion 64 protruding from the notch 75 of the cap 8. This pulling causes the inner peripheral fitting protrusion 67 of the engagement tube 65 of the cap 8 to move over the outer peripheral fitting protrusion 42 of the nozzle 41 and above the outer peripheral fitting protrusion 42, disengaging the cap 8 from the inner plug 4, and the cap 8 is removed from the container 5.

Here, whether the cap 8 rotates independently of the container 5 or together with the inner plug 4 depends on the state of the operating part 64 of the cap 8.

The engagement between the cap 8 and the inner plug 4 will be explained using Figures 7 and 8. Figure 7 is an explanatory diagram of the operation when removing the cap 8 and the inner plug 4 from the capped container 10 of the embodiment. Figure 8 is an explanatory cross-sectional diagram of the engagement between the lower part of the cap 8 and the inner plug 4 in different states of the embodiment. Figure 8 corresponds to the C-plane cross-sectional view of Figures 2 and 3.

As described above, the helical protrusion 23 is provided on the inner peripheral surface of the mouth portion 2 of the container body 3, and the helical protrusion 48 is provided on the outer peripheral surface of the tubular portion 47 of the inner stopper 4. Therefore, in a normal state of use, the helical protrusion 23 of the mouth portion 2 and the helical protrusion 48 of the inner stopper 4 engage with each other, so that the inner stopper 4 engages with the container body 3.

In FIG. 7, the helical protrusion (screw protrusion) 48 of the inner plug 4 is provided on the outer circumferential surface of the tube portion 47 at least once, and part of the helical protrusion 48 is formed double, and the details of the helical protrusion 23 of the mouth portion 2 are not shown. It is sufficient that either the helical protrusion 23, 48 provided on the mouth portion 2 or the inner plug 4 is provided at least once in the circumferential direction.

As described above, the operating portion 64 of the inner cap 6 is an elastically deformable cantilever-shaped engagement piece that protrudes outward from the lower cylinder 63, which is another area in the circumferential direction. A pair of locking ribs (641a, 642a) and (641b, 642b) are provided on the inside of the operating portions 64a and 64b. In addition, locking projections 44a and 44b are provided on the outer peripheral surface of the wide nozzle 41K at the lower end of the nozzle 41 of the middle plug 4.

When the cap 8 and the container 5 are engaged and no force is being applied to the operating part 64, as shown in FIG. 8(a), the locking rib pairs (641a, 642a) and (641b, 642b) of the operating parts 64a and 64b sandwich the locking protrusions 44a and 44b in the circumferential direction, but are in positions that do not interfere with each other in the radial direction. Therefore, in this positional relationship, the cap 8 can rotate independently of the nozzle 41, as shown in FIG. 6(d) to FIG. 6(f).

On the other hand, when the cap 8 and the container 5 are engaged, an external force is applied to the operating parts 64a and 64b, so that the pair of locking ribs (641a, 642a) and (641b, 642b) of the operating parts 64a and 64b pinch the locking protrusions 44a and 44b of the inner plug body 4 and come to a position where they interfere with each other in the radial direction, as shown in FIG. 8(b).

When the cap 8 is rotated slightly while maintaining the pressed state in FIG. 8(b), the locking ribs 641a, 641b of the operating parts 64a, 64b come into contact with the locking projections 44a, 44b of the inner plug body 4 from the side, as shown in FIG. 8(c). In this state, the rotation of the cap 8 relative to the inner plug body 4 is restricted, and the cap 8 and the inner plug body 4 can rotate together relative to the container body 3.

In this way, by rotating the inner stopper body 4 together with the cap 8 relative to the mouth portion 2 while the operating portion 64 of the cap 8 is pressed, the screw engagement between the helical protrusion 48 of the lower tubular portion 47 of the inner stopper body 4 and the helical protrusion 23 of the mouth portion 2 is released, and the cap 8 and the inner stopper body 4 can be removed together from the mouth portion 2 of the container body 3.

As shown in FIG. 8(b), the handle for rotation in this case is the outer peripheral surface of the operating portion 64 of the cap 8, which has an outer diameter larger than the outer edge of the annular closure plate 46, which is the maximum diameter of the inner stopper body 4. Therefore, when the cap 8 and inner stopper body 4 are rotated relative to the mouth 2, the torque is large and they become easier to turn. In this way, a rotational force is applied to the outer surface of the cap 8, and because the torque during rotation is large, the user can remove the inner stopper body 4 together with the cap 8 from the container body 3 with little force.

In addition, in Figs. 1 and 4, the helical protrusion 48 of the inner plug 4 and the helical protrusion 23 of the mouth portion 2 are shown as examples of single-start threads, but the helical protrusion 48 or the helical protrusion 23 may be a multiple-start thread. In the case of a multiple-start thread, the inner plug 4 can be attached and detached with fewer turns than with a single-start thread.

As shown in Figures 2 to 4, the nozzle 41 of the inner plug 4 has a multi-stage outer shape with a diameter that increases from top to bottom. As shown in Figure 8, the tube ribs 631, 632 of the lower tube 63 of the inner cap 6 are in contact with or close to the outer circumferential surface of the central nozzle 41M in the cap engagement state. This configuration prevents the cap 8 from tilting relative to the nozzle 41 when the cap 8 and inner plug 4 are rotated relative to the mouth 2 or when the cap 8 is attached to or detached from the container 5.

In addition, in Figures 8(b) and 8(c), the two operating parts 64a, 64b on the cap 8 are both shown pressed in, but simply pressing one of the operating parts 64a, 64b will cause the locking rib 641a or 641b to come into contact with the locking protrusion 44a or 44b of the inner plug body 4 from the side, so that the operation of removing the inner plug body 4 can be achieved.

Figure 9 is an explanatory diagram showing the state in which the inner plug 4 and the cap 8 have been removed from the capped container 10 of the first embodiment. Figure 5 shows the state in which the container is in use when the remaining amount of contents is low.

As described above, the cap 8 and the inner plug 4 can be removed from the mouth 2 of the container body 3 by pressing the operating portion 64 of the cap 8 and rotating the cap relative to the mouth 2.

In this way, by removing the inner stopper 4 together with the cap 8 from the container body 3, the user can insert a finger F, a cotton swab, or other object into the storage section 1 (tube) of the container body 3 as shown in FIG. 9, allowing the contents to be used to the last drop. This makes it possible to reduce the amount of the contents that are discarded after use, along with the container body 3.

In this case, as shown in Figure 9, the inner stopper body 4 can be placed with the cap 8 facing down, so that when the remaining amount is low and the contents are scooped up and used, the hand on the other side does not get dirty, and the surface where the inner stopper body 4 is temporarily placed, such as a desk or washstand, is prevented from getting dirty, which is hygienic. In this case, as shown in Figures 2 and 3, the upper surface of the outer top surface 71 of the outer cap 7 of the cap 8 is flat and its outer shape is equal to or larger than the other parts of the cap 8. Therefore, the cap 8 engaged with the inner stopper body 4 can be stably placed on a surface such as a desk.

In addition, the cap 8 and the inner plug 4 can be placed on a desk or other surface without worrying about soiling the surface, leaving both hands free. As shown in Figure 9, one hand can be used to hold the container body 3 while the other hand can be used to wipe off the contents.

As described above, in the capped container 10 of the present disclosure, when attaching or detaching the cap 8, the cap 8 is gripped at a part other than the operating part 64 and moved up and down, and rotated as necessary. On the other hand, when attaching or detaching the inner stopper 4, the cap 8 is rotated while the operating part 64 is pressed. Therefore, when removing the inner stopper 4 when there is only a little remaining, the user can easily use the cap 8 operation according to the purpose, since, in contrast to the simple capping operation during normal use, the button-like operating part 64 is pressed in addition to the cap 8 operation.

In addition, as shown in FIG. 9, the inner plug 4 can be attached and detached from the container body 3, so the container body 3 can be replaced with the inner plug 4 as a refill.

In other words, the container body 3, consisting of the storage section 1 and the mouth section 2, becomes a replaceable (removable and replaceable) refill together with the viscous substance contained therein. On the other hand, the inner stopper 4 and the cap 8 are reused after replacing the refill.

As a result, the empty container body 3 can be replaced with a new refill of the same shape, and the inner stopper body 4 and cap 8 can be reused. This reduces the amount of waste resin.

The container body 3, which can be replaced as a refill, can have the top surface of the mouth 2 covered with a film or a cover that surrounds the mouth. This allows the container body 3, which is a refill, to be distributed separately.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited to the specific embodiment, and various modifications and changes are possible within the scope of the gist of the embodiment of the present invention described in the claims.
