JP7635633B2 - Storage container and packaging - Google Patents

Description

The present invention relates to a storage container capable of storing a replacement container and a package that stores a replacement container in the storage container.

A conventional container for storing consumable contents such as hair styling products is disclosed in Patent Document 1. This container comprises a container body and a lid. This container often uses resin to prevent the contents from drying out and to prevent odor components from leaking to the outside.

Patent No. 6826748

However, with the conventional containers described above, the plastic container must be discarded each time the contents are consumed, which increases the amount of plastic discarded and may lead to an increased environmental burden.

The present invention aims to provide a storage container and packaging body that can reduce the environmental impact.

To achieve the above object, the storage container of the present invention stores a replacement container in an internal space in a replaceable manner. The storage container has a bottomed cylindrical container body with an opening at the top, an inner lid part that is attached to the opening of the container body and presses the upper end of the replacement container downward, and a lid part that closes the opening of the container body and the inner lid part in an openable and closable manner. The lid part has a pressing rib that extends downward from a surface facing the inner lid part and presses the inner lid part.

By configuring it in this way, the storage container can be reused after the contents are used up, and only the replacement container is replaced, so the amount of waste resin can be reduced compared to when the storage container is discarded. This reduces the environmental impact.

In the storage container having the above configuration, the inner lid portion is annular. This configuration makes it easy to attach the inner lid portion.

In the storage container of the above configuration, the inner lid portion has an inner lid tube portion that contacts the inner peripheral surface of the opening of the container body, and a flange portion that spreads outward from the upper end of the inner lid tube portion and contacts the upper surface of the container body. With this configuration, it is possible to seal the internal space of the storage container, and the contents can be preserved for a long period of time. This reduces the amount of waste of storage containers and replacement containers containing the contents, and reduces the environmental burden.

In the storage container of the above configuration, the inner lid portion has an inner lid tubular portion that contacts the inner circumferential surface of the opening of the container body, and a flange portion that spreads outward from the upper end of the inner lid tubular portion and contacts the container body. It has a fitting portion that fits the container body and the inner lid portion. The fitting portion has a fitting protrusion that protrudes toward the other from at least one of the inner circumferential surface of the opening and the outer circumferential surface of the inner lid portion, and a fitting recess that is formed on the side opposite to the side on which the fitting protrusion is formed on the inner circumferential surface of the opening and the outer circumferential surface of the inner lid portion, and into which the fitting protrusion can be fitted. This allows the inner lid portion to be fixed more firmly to the container body. As a result, it is possible to fix the storage container by suppressing rotation with the inner lid portion.

In the storage container having the above configuration, the inner lid portion is formed of an elastically deformable material. This makes it possible to more reliably seal the internal space.

In the storage container of the above configuration, the container body and the lid are engaged at an engagement portion, which has a male thread portion formed on the container body and a female thread portion formed on the lid that can be screwed into the male thread portion.

The packaging body of the present invention is a packaging body having any of the above-mentioned storage containers and the replacement container made of paper. It is formed by folding a blank plate made of paper and is fitted into a bottomed cylindrical container body.

The present invention provides a storage container that reduces the environmental impact.

<Package A>
1 to 3, the package A has a storage container 1 and a replacement container 2 accommodated in an internal space 1S formed inside the storage container 1. The replacement container 2 is accommodated in the internal space of the storage container 1 in a replaceable manner.

In the package A, the contents S are stored inside the replacement container 2. The contents are assumed to be, for example, a gel-like hair styling product, but are not limited to this. Examples include gel-like foods such as yogurt and jam, and lubricants such as grease. The contents S can be a wide variety of items that are used in small amounts. After the contents S of the replacement container 2 are used up, the replacement container 2 is removed from the storage container 1, and the replacement container 2 filled with the contents S, in other words, a new replacement container 2, is stored in the storage container 1. In this way, the storage container 1 can continue to be used even after the contents S are used up.

<Storage container 1>
The storage container 1 has a container body 10, a lid portion 20, and an inner lid portion 30. The lid portion 20 is detachably attached to the container body 10. In other words, the lid portion 20 closes an opening 100 of the container body, which will be described later, in an openable and closable manner. The container body 10 and the lid portion 20 may be formed of a thermoplastic resin, such as polypropylene (PP), polystyrene (PS), or polyethylene terephthalate (PET). The container body 10 and the lid portion 20 are not limited to these resins, and can widely adopt resins that are easy to mold. They may also be formed of a metal material such as a metal or an alloy. In this embodiment, the container body 10 and the lid portion 20 are configured to be formed of the same material, but are not limited thereto, and the container body 10 and the lid portion 20 may be formed of different materials.

<Container body 10>
1 to 3, the container body 10 is in the shape of a bottomed cylinder having an opening 100 at its upper portion. The container body 10 has a bottom plate portion 11, a side wall portion 12, and an upper cylinder portion 13.

The bottom plate portion 11 is disk-shaped. However, this is not limited to this, and any shape capable of supporting the lower end portion of the replacement container 2 can be widely adopted.

The side wall portion 12 is cylindrical and extends vertically around the central axis Cx. As shown in FIG. 2, the cross-sectional shape of the side wall portion 12 cut along a plane including the central axis Cx is a curved shape with the vertical middle portion bulging outward in the radial direction. However, this is not limited to this, and the cross-sectional shape may be one that expands linearly upward. A wide variety of shapes that allow the replacement container 2 to be easily attached and detached can be adopted. The bottom plate portion 11 expands radially inward from a position shifted upward from the lower end of the side wall portion 12. In other words, the lower end portion of the side wall portion 12 is shaped to match the shape of the bottom plate portion 11.

For example, the bottom plate portion 11 may be square shaped. In such a case, the side wall portion 12 has a shape in which the lower end matches the square shape. Even in this case, the upper end surface of the side wall portion 12 is annular.

The upper tube portion 13 is cylindrical and extends upward from the upper end surface of the side wall portion 12 along the central axis Cx. The outer diameter of the upper tube portion 13 is smaller than the outer diameter of the upper end of the side wall portion 12. The inner diameter of the upper tube portion 13 is the same as the inner diameter of the side wall portion 12. In other words, the inner peripheral surface of the side wall portion 12 and the inner peripheral surface of the upper tube portion 13 are smoothly connected. The outer peripheral surface of the upper tube portion 13 is formed with a male thread portion 41 of the engagement portion 40, which will be described later.

An opening 100 is formed at the upper end of the upper tube portion 13. An inner lid portion 30 is attached to the opening 100. As will be described in detail later, the opening 100 can be used as an outlet for removing the replacement container 2 placed inside after the contents S have been consumed. For this reason, the inner diameter of the opening 100 is the same as or larger than the outer diameter of the flange portion 203 of the replacement container 2.

<Cover portion 20>
The lid portion 20 is removably disposed on the upper portion of the container body 10. More specifically, the lid portion 20 is removably disposed on the upper portion of the upper tube portion 13 of the container body 10. When the lid portion 20 is attached to the upper portion of the container body 10, an upper opening 34 (described later) of the inner lid portion 30 attached to the opening 100 at the upper portion of the container body 10 is closed. When the lid portion 20 is detached from the container body 10, the upper opening 34 of the inner lid portion 30 attached to the opening 100 is closed (see FIGS. 2 and 5).

The lid portion 20 has a top plate portion 21, a lid tube portion 22, and a pressing rib 23. The top plate portion 21 is a circular plate whose center overlaps with the central axis Cx. The lid tube portion 22 extends downward from the outer edge of the top plate portion 21. The lid tube portion 22 is cylindrical and centered on the central axis Cx. A female thread portion 42 of the engagement portion 40, which will be described later, is formed on the inner peripheral surface of the lid tube portion 22.

The pressing rib 23 extends downward from the underside of the top plate 21 along the central axis Cx. As shown in FIG. 4, the pressing rib 23 is cylindrical. When the lid 20 is attached to the top of the container body 10, it comes into contact with an upper flange 32 (described later) of the inner lid 30. More specifically, the pressing rib 23 is in close contact with the inner lid 30. Note that close contact refers to a state in which the drying of the contents S is suppressed and the contents S are tight enough to prevent odor components from leaking out. In the following explanation, close contact refers to a similar state.

<Inner lid portion 30>
The inner lid portion 30 is attached to the container body 10. The inner lid portion 30 is formed of an elastically deformable material such as silicone or polyethylene. The inner lid portion 30 is cylindrical and extends in a direction along the central axis Cx. As shown in FIG. 3 and other figures, the inner lid portion 30 has an inner lid tube portion 31, an upper flange portion 32, and a lower flange portion 33. The inner lid tube portion 31 is cylindrical and has an outer diameter equal to the inner diameter of the opening 100 of the container body 10. The inner lid tube portion 31 has an upper opening 34 at its upper end.

The upper flange portion 32 is annular and expands radially outward from the upper end of the outer circumferential surface of the inner lid tube portion 31. The upper flange portion 32 is perpendicular to the central axis Cx. When the inner lid portion 30 is attached to the opening 100 of the container body 10, the upper flange portion 32 comes into contact with the upper surface 131 of the upper tube portion 13. The upper flange portion 32 comes into contact with the upper surface 131 of the upper tube portion 13, thereby positioning the inner lid portion 30 in the direction of the central axis Cx.

The lower flange portion 33 is annular and extends radially inward from the lower end of the inner lid tube portion 31. The lower flange portion 33 is perpendicular to the central axis Cx. When the inner lid portion 30 is attached to the opening 100 of the container body 10, the lower flange portion 33 comes into contact with the upper surface of the flange portion 203 of the replacement container 2.

A lower opening 35 is formed radially inside the lower flange portion 33, penetrating in a direction along the central axis Cx. The contents S contained in the replacement container 2 contained in the internal space 1S are removed through the lower opening 35. More specifically, the contents S removed from the replacement container 2 through the lower opening 35 pass through the inner lid tube portion 31 and are removed to the outside through the upper opening 34.

The inner lid portion 30 is press-fitted into the opening 100 of the container body 10. To explain further, the inner lid tube portion 31 of the inner lid portion 30 is inserted into the opening 100 while its outer circumferential surface is in contact with the inner circumferential surface of the opening 100. This increases the frictional force between the outer circumferential surface of the inner lid tube portion 31 and the inner circumferential surface of the opening 100. As a result, the inner lid portion 30 is less likely to come off the container body 10. In other words, by pushing the inner lid portion 30 into the opening 100, the lower flange portion 33 presses the flange portion 203 of the replacement container 2. As a result, the inner lid portion 30 fixes the replacement container 2 inside the container body 10 so that it does not rotate.

Also, as shown in FIG. 6, the container body 10 and the inner lid portion 30 may be fitted together by a fitting portion 50. FIG. 6 is an enlarged cross-sectional view of an example of a fitting portion 50 that fits the container body 10 and the inner lid portion 30 together. As shown on the left side of FIG. 6, the fitting portion 50 has a fitting protrusion 511 that protrudes radially inward from the inner peripheral surface of the opening 100 of the container body 10, and a fitting recess 521 that is recessed radially inward from the outer peripheral surface of the inner lid tube portion 31 of the inner lid portion 30. The inner lid portion 30 is attached to the container body 10 by fitting the fitting protrusion 511 into the fitting recess 521.

Also, as shown on the right side of FIG. 6, the fitting portion 50 may have a fitting protrusion 512 that protrudes radially outward from the outer peripheral surface of the inner lid tube portion 31 of the inner lid portion 30, and a fitting recess 522 that is recessed radially outward from the inner peripheral surface of the opening 100 of the container body 10. The inner lid portion 30 can also be attached to the container body 10 by fitting the fitting protrusion 512 into the fitting recess 522.

By using the fitting portion 50 to attach the inner lid portion 30 to the container body 10, the inner lid portion 30 becomes even less likely to come off the container body 10, and pressure on the flange portion 203 of the replacement container 2 is stabilized. This makes it possible to reliably prevent the replacement container 2 from rotating and fix it in place. The fitting portion 50 may have a fitting protrusion 511 and a fitting recess 521, or may have a fitting protrusion 512 and a fitting recess 522. It may also have all of these.

<Engagement portion 40>
The lid 20 is engaged with the container body 10 by an engagement portion 40. The engagement portion 40 has a male thread portion 41 formed on the outer peripheral surface of the upper cylindrical portion 13 of the container body 10 and a female thread portion 42 formed on the inner peripheral surface of the lid cylindrical portion 22 of the lid 20. The female thread portion 42 has a shape that allows it to be screwed into the male thread portion 41.

The lid portion 20 is placed on top of the container body 10, and the lid portion 20 is rotated in a clockwise direction when viewed from above in a direction along the central axis Cx. This causes the female thread portion 42 to screw into the male thread portion 41. This engages the lid portion 20 with the container body 10. The lid portion 20 can also be separated from the container body 10 by rotating the lid portion 20 in a counterclockwise direction.

The engagement portion 40 is formed by a screw mechanism. Therefore, by rotating the lid portion 20 in the direction in which the engagement portion 40 is tightened (here, the direction in which the right-handed screw is tightened), the lid portion 20 moves downward along the central axis Cx, in other words, so as to approach the bottom plate portion 11 of the container body 10. As a result, the pressing rib 23 formed on the underside of the top plate portion 21 of the lid portion 20 presses the upper flange portion 32 of the inner lid portion 30.

As a result, the upper flange portion 32 comes into close contact with the upper surface 131 of the upper tube portion 13 of the container body 10, and also comes into close contact with the lower surface of the pressing rib 23. In other words, the upper flange portion 32 acts as a gasket that seals the gap between the container body 10 and the lid portion 20. Also, as described above, the inner peripheral surface of the container body 10 and the outer peripheral surface of the inner lid tube portion 31 come into close contact with each other. Therefore, in the package A, by engaging the lid portion 20 with the upper portion of the container body 10, it is possible to prevent foreign matter such as dust, dirt, and moisture from entering the internal space 1S.

<Replacement container 2>
The replacement container 2 is accommodated in the internal space 1S of the storage container 1. The replacement container 2 can be removed 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 is a bottomed cylinder, and may be, for example, made of paper as a base material with an internal coating layer that has water resistance, gas barrier properties, etc. Examples of water-resistant coating layers include resin layers made of polyethylene (PE), polyethylene terephthalate (PET), etc. Examples of gas-barrier coating layers include aluminum layers. In other words, the layer formed on the inside is made of a material that does not react with the items stored therein.

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

As shown in Figures 2 and 3, the replacement container 2 has a bottom 201, a side wall 202, and a flange 203. The side wall 202 is cylindrical and extends vertically. In the replacement container 2, the side wall 202 is formed by bending a single plate-like member into a ring shape and gluing both ends. As shown in Figures 2, 3, etc., the side wall 202 has a shape that widens as it extends upward. However, it is not limited to this, and it may have a cross-sectional shape that is equal over its entire length, or may have a shape that narrows toward the top.

In the replacement container 2, the lower part of the side wall 202 is closed by the bottom 201. The bottom 201 is fixed at a position shifted upward from the lower end of the side wall 202 (see FIG. 2). This configuration can increase the rigidity of the bottom 201. If the replacement container 2 is an integrally molded resin body, the bottom 201 may be connected to the lower end of the side wall 202.

An opening 204 is formed at the upper end of the side wall portion 202 for inserting and removing the contents S stored inside. The opening 204 faces the bottom portion 201 vertically. The flange portion 203 extends radially outward from the upper end of the outer circumferential surface of the side wall portion 202. In other words, the flange portion 203 is positioned outside the opening 204.

<Resin sheet 205>
In the package A, the replacement container 2 is replaceably accommodated inside the storage container 1. For example, after the content S accommodated inside the replacement container 2 is used up, it is replaced with a separate, unused replacement container 2 and used. 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, a wide variety of resin films or laminates thereof having the functions required for sealing, such as sealing properties, water resistance, and gas barrier properties, can be used, such as PE resin and PE resin film, PET resin film, or laminates thereof. The resin sheet 205 is sealed to the flange portion 203 by, for example, heat sealing, but a sealing method other than heat sealing may also be used.

<How to use package A>
1 and 2, in the package A, the upper opening 34 of the inner lid part 30 is closed by engaging the lid part 20 with the container body 10. In addition, the upper opening 34 of the inner lid part 30 is opened by separating the lid part 20 from the container body 10 (see FIG. 5).

The package A is opened by separating the lid 20 from the container body 10. The user then inserts a finger or a tool such as a spoon (depending on the contents S) from the upper opening 34 to remove the contents S from the replacement container 2. As described above, the inner lid 30 is press-fitted or protrudingly fitted into the opening 100 of the container body 10.

Therefore, the lower end of the inner lid 30, including the lower flange 33, is kept pressed downward against the flange 203 of the replacement container 2. As a result, even when the lid 20 is removed, the replacement container 2 is pressed and fixed by the inner lid 30. Therefore, even if the user's fingers or a tool such as a spoon move along the inner circumferential surface of the side wall 202 of the replacement container 2 and a circumferential force is applied to the side wall 202, rotation of the replacement container 2 is suppressed. This allows the user to easily and reliably remove the contents S from the replacement container 2 even if there is only a small amount of the contents S remaining inside the replacement container 2.

After removing the contents S, the lid 20 is attached to the upper end of the container body 10. At this time, the pressing rib 23 of the lid 20 presses the upper flange 32 of the inner lid 30, and the upper flange 32 is pressed against the upper surface 131 of the upper tube 13 of the container body 10. This brings the container body 10 and the lid 20 into close contact. In this way, by closing the opening 100 with the lid 20, deterioration of the contents S, such as drying, can be suppressed, and odor particles in the contents S can be suppressed from leaking to the outside.

When the contents S inside the replacement container 2 are used up, the replacement container 2 is removed from the internal space 1S and a new replacement container 2 is placed in the internal space 1S. In other words, the empty replacement container 2 is replaced with an unused replacement container 2. Next, the procedure for replacing the replacement container 2 in the package A will be described with reference to the drawings. Figure 7 is a perspective view of the package showing the state in which the inner lid portion 30 is attached and detached. Figure 8 is a perspective view showing the state in which the used replacement container 2 has been removed from the container body 10. Figure 9 is a perspective view showing the state in which an unused replacement container 2 is attached to the container body 10.

As shown in FIG. 5, the lid 20 is removed from the container body 10. Then, as shown in FIG. 7, the inner lid 30 attached to the opening 100 of the container body 10 is removed. The inner lid 30 is press-fitted into the opening 100. Therefore, when removing the inner lid 30, the user inserts his/her finger or a tool such as a flathead screwdriver into the lower opening 35 and hooks it onto the underside of the lower flange 33 and pulls it up. This causes the inner lid 30 to be removed from the opening 100 while elastically deforming.

The inner lid portion 30 may be provided with a protrusion for removal. For example, a protrusion for removal may be a protrusion extending radially inward from the upper end of the inner lid tube portion 31. When the inner lid portion 30 has a protrusion for removal, the inner lid portion 30 can be removed from the container body 10 by pinching and lifting the protrusion.

By removing the inner lid portion 30 from the container body 10, the replacement container 2 housed inside the internal space 1S of the container body 10 can be moved upward. By lifting the replacement container 2 upward, the replacement container 2 can be removed from the container body 10 (see FIG. 8).

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

The inner lid 30 is pressed into the opening 100 at the top of the container body 10 in which the replacement container 2 is housed (see FIG. 7). This presses the flange 203 of the replacement container 2 against the underside of the inner lid 30. As a result, the replacement container 2 is fixed to the container body 10 (see FIG. 5). The lid 20 is then placed on top of the container body 10 and rotated clockwise, so that the male thread 41 and female thread 42 of the engagement portion 40 screw together. By firmly tightening the engagement portion 40, the pressing rib 23 of the lid 20 presses the upper flange 32 of the inner lid 30. This seals the internal space 1S of the container body 10.

In this manner, the internal space 1S of the storage container 1 is sealed. This makes it possible to prevent the contents S inside the replacement container 2 from deteriorating due to drying, etc. In addition, the contents S can be stored and maintained in the internal space 1S while preventing the leakage of odor components.

If there are no plans to use the contents S in the near future, the contents S may be placed inside the container body 10 with the resin sheet 205 still attached. In this way, by keeping the resin sheet 205 attached, deterioration of the contents S can be suppressed.

In the package A of the present invention, after the contents S are used up, the replacement container 2 is replaced to replenish the contents S. This allows the storage container 1 to be used for a long period of time, and it is possible to reduce the consumption of parts made of synthetic resin compared to the case where the storage container 1 is discarded every time the contents S is used up. This reduces the amount of synthetic resin consumed and disposed of, and reduces the environmental burden. In addition, by making the replacement container 2 out of paper, it is possible to further reduce the amount of synthetic resin used and disposed of, and further reduce the environmental burden.

For example, it is possible to combine multiple types of storage containers 1 with different colors, shapes, etc. and multiple replacement containers 2 with different contents S in advance according to the user's preferences. This allows the user to continue using a storage container 1 that he or she likes. This makes it possible to provide a package A that suits the user's preferences. Furthermore, the appearance of the storage container 1 may be changed depending on the contents S. In this way, the user can distinguish the contents S from the appearance of the storage container 1, making it possible to accurately use multiple types of contents S without opening the lid 20 to check.

The present invention is not limited to the above-mentioned configuration, and various modifications are possible. Configurations obtained by appropriately combining the technical means disclosed in different configurations are also included in the technical scope of the present invention.

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