The lid base portion 21 and the lid opening/closing portion 22 are connected via the lid hinge portion 30 . The lid hinge portion 30 is a member that folds at its intermediate portion. The lid hinge portion 30 is deformable between a folded state and an extended state. When the lid hinge portion 30 is folded (see FIG. 3), the lid opening/closing portion 22 is arranged above the lid base portion 21 and closes the lid portion opening 23 . Further, when the lid hinge portion 30 is in the extended state (see FIGS. 2 and 4), the lid opening/closing portion 22 is arranged at a position where the lid hinge portion 30 is centered. Thereby, the lid opening 23 is opened.

<Engaging portion 40>
The lid portion 20 is engaged with the container body 10 by the engaging portion 40 . The engaging portion 40 has a male threaded portion 41 formed on the outer peripheral surface of the upper tubular portion 13 of the container body 10 and a female threaded portion 42 formed on the inner peripheral surface of the lid tubular portion 211 of the lid portion 20 . The female threaded portion 42 has a shape that can be screwed onto the male threaded portion 41 .

The lid portion 20 is placed on the upper portion of the container body 10, and is rotated clockwise as viewed from above in the direction along the central axis Cx. Thereby, the female threaded portion 42 is screwed with the male threaded portion 41 . Thereby, the lid portion 20 is engaged with the container body 10 . Further, the lid portion 20 can be separated from the container body 10 by rotating the lid portion 20 counterclockwise.

The engaging portion 40 is formed with a screw mechanism. Therefore, by rotating the lid portion 20 in the direction in which the engaging portion 40 is tightened (here, in the direction in which the right-hand thread is tightened), the lid portion 20 moves downward along the central axis Cx, in other words, the container body 10 It moves so as to approach the bottom plate portion 11 . As a result, the container main body 10 and the lid portion 20 are in close contact with each other. Note that close contact means a state in which drying of the contents S is suppressed and the odor components of the contents S are not leaked out. Close contact in the following description refers to a similar state. As a result, in the package A, foreign matter such as dust, dirt, and moisture can be prevented from entering the internal space 1S from the outer peripheral surface of the container 1 .

<Replacement container 2>
The replacement container 2 is housed in the internal space 1S of the housing container 1 . The replacement container 2 can be taken out from the internal space 1S. That is, the replacement container 2 can be replaced with respect to the storage container 1 .

The replacement container 2 has a cylindrical shape with a bottom. For example, it may have a configuration in which paper is used as a base material and a coating layer having water resistance, gas barrier properties, etc. is provided inside. Examples of water-resistant coating layers include resin layers made of polyethylene (PE), polyethylene terephthalate (PET), and the like. Moreover, an aluminum layer can be mentioned as the coating layer having a gas barrier property. That is, the layer formed inside is formed of a material that does not react with the stored articles.

Note that the replacement container 2 may be a molding of thermoplastic resin such as polypropylene (PP) or polystyrene (PS). Further, the replacement container 2 is not limited to these resins, and a wide range of resins that are easy to mold can be used. When the replacement container 2 is used to store food, at least the inner surface is made of a material that is non-toxic or substantially non-toxic to the human body. Examples of molding methods include injection molding and drawing, but are not limited to these.

As shown in FIGS. 2 and 3 , the replacement container 2 has a bottom portion 201 , a side wall portion 202 and a flange portion 203 . The side wall portion 202 has a tubular shape extending vertically. In the replacement container 2, the side wall portion 202 is formed by bending a single plate-like member into an annular shape and adhering both ends thereof. As shown in FIGS. 2, 3, etc., the side wall portion 202 has a shape that widens upward. However, it is not limited to this, and may have a uniform cross-sectional shape over the entire length, or may have a shape that narrows upward.

In the replacement container 2 , the lower portion of the side wall portion 202 is closed by the bottom portion 201 . The bottom portion 201 is fixed at a position shifted upward from the lower end portion of the side wall portion 202 (see FIG. 2). By configuring in this way, the rigidity of the bottom portion 201 can be increased. When the replacement container 2 is an integrally molded resin body, the bottom portion 201 may be connected to the lower end portion of the side wall portion 202 .

An opening 204 is formed in the upper end portion of the side wall portion 202 for taking in and out the content S accommodated therein. The opening 204 vertically faces the bottom portion 201 . The flange portion 203 extends radially outward from the upper end of the outer peripheral surface of the side wall portion 202 . That is, the flange portion 203 is arranged outside the opening 204 .

As shown in FIG. 3 , the replacement container 2 is placed inside the container body 10 , and the lid portion 20 is placed on top of the container body 10 . Then, the male threaded portion 41 and the female threaded portion 42 of the engaging portion 40 are engaged by rotating the lid portion 20 in a tightening direction. By further occupying the lid portion 20 in the tightening direction, the lid portion 20 moves downward, so that the pressing portion 215 of the lid portion 20 presses the flange portion 203 of the replacement container 2 downward. As a result, the replacement container 2 is fixed inside the container body 10 in a state in which rotation about the central axis Cx is suppressed.

<Resin sheet 205>
In the package A, the replacement container 2 is housed inside the housing container 1 so as to be replaceable. For example, after the content S housed inside the replacement container 2 is used up, it is separately replaced with an unused replacement container 2 for use. The upper end of the unused replacement container 2 is sealed with a resin sheet 205 .

The resin sheet 205 covers the opening 204 at the upper end of the side wall portion 202 and is sealed to the flange portion 203 . As the resin sheet 205, for example, a PE resin, a PE resin film, a PET resin film, or a laminate thereof, or a resin film or a laminate thereof having functions necessary for sealing such as sealability, water resistance, and gas barrier properties, is widely adopted. can do. The sealing of the resin sheet 205 to the flange portion 203 is performed, for example, by heat sealing, but a sealing method other than heat sealing may be employed.

<About the use of package A>
As shown in FIGS. 1 and 2, in the package A, the lid opening 23 is opened by lifting the opposite side of the lid opening/closing portion 22 of the lid portion 20 across the central axis Cx of the lid hinge portion 30. be At this time, the lid hinge portion 30 is maintained in an extended state.

Further, by rotating the lid opening/closing portion 22 downward about the lid hinge portion 30 with the lid portion opening 23 being opened, the lid opening/closing portion 22 is arranged above the lid base portion 21 . At this time, the ring portion 223 projecting downward from the lower surface of the top plate portion 221 of the lid opening/closing portion 22 is arranged inside the upper cylinder portion 213 of the lid base portion 21 . Thereby, the lid opening 23 is closed.

At this time, the outer peripheral surface 224 of the ring portion 223 is in close contact with the inner peripheral surface 214 of the upper cylinder portion 213 . The upper tubular portion 213 and the ring portion 223 of the lid portion 20 serve as a packing that closes the gap of the lid portion opening 23 . In this embodiment, the ring portion 223 is accommodated inside the upper cylindrical portion 213 when the lid opening/closing portion 22 is closed. However, it is not limited to this, and the ring portion 223 may be arranged outside the upper tubular portion 213 . In this case, the inner peripheral surface of the ring portion 223 is in close contact with the outer peripheral surface of the upper cylinder portion 213 .

The user lifts up the lid opening/closing part 22 to open the lid opening 23 . In this state, the user's fingers or a tool such as a spoon is inserted into the internal space 1S of the container body 10 through the lid opening 23, and the contents S stored in the replacement container 2 are taken out.

When the content S accommodated inside the replacement container 2 is running low, the user can move a tool such as a finger or a spoon along the bottom portion 201 and/or the side wall portion 202 of the replacement container 2 along the central axis Cx. is moved in the circumferential direction around the center. At this time, force is applied to the replacement container 2 in the circumferential direction around the central axis Cx. As described above, the replacement container 2 is pressed and fixed by the pressing portion 215 . Therefore, even if a circumferential force is applied to the bottom portion 201 and/or the side wall portion 202, the rotation of the replacement container 2 is suppressed. As a result, the user can easily and reliably take out the content S remaining inside the replacement container 2 even when the content S is reduced.

After the content S is taken out, the lid opening 23 is closed by rotating the lid opening/closing portion 22 downward around the lid hinge portion 30 . Thus, the opening 100 is closed by closing the lid opening 23 with the lid opening/closing portion 22 . At this time, since the upper cylindrical portion 213 and the ring portion 223 are in close contact with each other at the lid opening 23, deterioration such as drying of the contents S can be suppressed, and odor particles of the contents S can be suppressed from leaking to the outside.

When the content S inside the replacement container 2 is used up, the replacement container 2 is taken out from the internal space 1S and a new replacement container 2 is accommodated in the internal space 1S. That is, the empty replacement container 2 is replaced with an unused replacement container 2 . Next, a procedure for replacing the replacement container 2 in the package A will be described with reference to the drawings. FIG. 7 is a perspective view of the package A showing a state in which the lid portion 20 is attached and detached. FIG. 8 is a perspective view showing a state in which the used replacement container 2 is removed from the container body 10. FIG. FIG. 9 is a perspective view showing a state in which an unused replacement container 2 is attached to the container body 10. FIG.

As shown in FIG. 7, the lid portion 20 is removed from the container body 10 . By removing the lid portion 20 from the container main body 10, the replacement container 2 accommodated inside the internal space 1S of the container main body 10 can be moved upward. By lifting up the replacement container 2, the replacement container 2 is removed from the container body 10 (see FIG. 8).

Then, an unused replacement container 2 is attached. When the content S is to be used immediately or is planned to be used in the near future, the resin sheet 205 is peeled off from the flange portion 203 and removed, and then the replacement container 2 is placed inside the container body 10 ( See Figure 9). On the other hand, there are cases where the contents S are housed and stored inside the container body 10 for a long period of time. In this case, the replacement container 2 may be accommodated in the internal space 1S without peeling off the resin sheet 205 .

The replacement container 2 is placed on top of the container body 10 containing the replacement container 2, and the lid portion 20 is rotated clockwise. As a result, the male threaded portion 41 and the female threaded portion 42 of the engaging portion 40 are screwed together. By firmly tightening the engaging portion 40, the internal space 1S of the container body 10 is sealed.

Further, by tightening the engaging portion 40 firmly, the lid portion 20 moves toward the container body 10 . As a result, the pressing portion 215 of the lid portion 20 presses the upper surface of the flange portion 203 of the replacement container 2 downward. Thereby, the replacement container 2 is fixed in the internal space 1S of the storage container 1 .

As described above, in the package A, the replacement container 2 is fixed to the container 1, and the internal space 1S of the container 1 is sealed. As a result, deterioration of the content S inside the replacement container 2 due to drying or the like can be suppressed. In addition, the contents S can be accommodated and held in the internal space 1S while suppressing leakage of odor components.

If there is no plan to use the content S in the near future, it may be placed inside the container body 10 with the resin sheet 205 still attached. By maintaining the state in which the resin sheet 205 is attached in this manner, the deterioration of the contents S can be suppressed.

In the package A according to the present invention, the content S is replenished by replacing the replacement container 2 after the content S is used up. Therefore, the storage container 1 can be used for a long period of time, and the amount of consumption of members made of synthetic resin can be reduced compared to the case where the storage container 1 is discarded each time the content S runs out. As a result, the amount of synthetic resin consumed and discarded can be reduced, and the environmental load can be reduced. Moreover, by making the replacement container 2 made of paper, it is possible to further reduce the amount of synthetic resin used and the amount of waste, thereby further reducing the environmental load.

Further, for example, it is possible to combine a plurality of types of storage containers 1 having different colors, shapes, etc., and a plurality of replacement containers 2 having different contents S according to user's preference. Thereby, the user can continue to use the container 1 that he likes. Therefore, it is possible to provide the package A that matches the taste of the user. Furthermore, depending on the content S, the appearance of the container 1 may be changed. By doing so, the user can distinguish the contents S from the appearance of the container 1, so that it is possible to correctly use a plurality of types of contents S properly without opening the lid part 20 and checking. .

It should be noted that the present invention is not limited to the configuration described above, and various modifications are possible, and configurations obtained by appropriately combining technical means disclosed in different configurations are also within the technical scope of the present invention. included.

According to the present invention, by replacing only the replacement container, the container can be used for a long period of time as a container for storing contents such as hair styling products and foods.
