In the state where the container is housed in the conventional container holder described above, there is a problem that it is difficult to maintain the temperature of the container because the lower surface of the container is exposed to the outside.

An object of the present invention is to solve the above-mentioned problems and to provide a container holder having excellent cold and heat retention properties of the container and a blank sheet of the container holder.

In order to solve the above problems, the present invention is a container holder for accommodating a bottomed tubular container, which is a tubular body having a bonded portion formed by bonding both ends of a wall plate. A bottom plate fitted to the lower part of the body portion is provided. The wall plate is made of single-sided corrugated cardboard, and a plurality of flutes of the single-sided corrugated cardboard are exposed on the inner surface of the wall plate. On the inner surface of the wall plate, a mounting groove formed by cutting out the core of the single-sided corrugated cardboard extends in the circumferential direction . The outer peripheral edge of the bottom plate is fitted in the mounting groove. The mounting groove is divided by a convex portion, which is a portion where the core of the single-sided corrugated cardboard is not cut off, and a concave portion formed on the outer peripheral edge portion of the bottom plate is fitted into the convex portion.

In the container holder of the present invention, when the container is housed in the body, an air layer is formed on the outer periphery of the container by the internal space of each flute of the wall plate and the space between the adjacent flutes. In addition, the lower surface of the container is covered with a bottom plate. Thereby, in the container holder of the present invention, the cold insulation property and the heat retention property of the container can be enhanced.
Further, in the container holder of the present invention, the bottom plate can be positioned above the lower end portion of the body portion. As a result, when the container holder is placed on a table or the like, a space can be formed between the bottom plate and the mounting surface, so that the cold insulation and heat retention of the lower portion of the container can be improved.

In the container holder described above, it is preferable that the bottom plate is made of single-sided corrugated cardboard, and a plurality of flutes of the single-sided corrugated cardboard are exposed on the upper surface of the bottom plate.
In this configuration, when the container is housed in the body, an air layer is formed under the container by the internal space of each flute on the bottom plate and the space between adjacent flutes, so that the cold and heat retention of the lower part of the container is maintained. Can be enhanced.

Another configuration of the present invention is a blank sheet of a container holder for accommodating a bottomed tubular container, which includes a wall plate and a bottom plate. The wall plate is a rectangular single-sided corrugated cardboard having a plurality of flutes formed on one side, and a mounting groove for attaching the bottom plate is cut off from the core of the single-sided corrugated cardboard on the one-sided side of the single-sided corrugated cardboard. The mounting groove is formed and extends in the longitudinal direction of the single-sided corrugated cardboard. The mounting groove is divided by a convex portion, which is a portion where the core of the single-sided corrugated cardboard is not cut off, and a concave portion fitted to the convex portion is formed on the outer peripheral edge portion of the bottom plate.

In the present invention, a tubular body can be formed by bending a blank sheet so that one side of the single-sided corrugated cardboard is on the inside and bonding both ends of the blank sheet.
When the container is housed in the body, an air layer is formed on the outer periphery of the container by the internal space of each flute and the space between adjacent flutes.
Further, by inserting the outer peripheral edge portion of the bottom plate into the mounting groove of the blank sheet, the bottom plate can be positioned above the lower end portion of the body portion. As a result, the lower surface of the container is covered with the bottom plate, and a space is formed between the bottom plate and the mounting surface such as a table.
As described above, the container holder using the blank sheet of the present invention can improve the cold and heat retention of the container.

With the container holder of the present invention, it is possible to improve the cold and heat retention of the container while suppressing the manufacturing cost. Further, in the blank sheet of the present invention, it is possible to suppress the manufacturing cost and to form a container holder having excellent cold and heat retention properties of the container.

Embodiments and reference examples of the present invention will be described in detail with reference to the drawings as appropriate.
In the following description, the front-back and left-right directions are set for convenience in explaining the container holder of the present embodiment and the reference example , and do not limit the configuration of the container holder.

In the reference example , as an example of the container holder of the present invention, as shown in FIG. 2, the container holder 1 in which the drinking water cup C is housed will be described.
The container holder 1 of the reference example includes a tubular body portion 10 and a bottom plate 20 fitted in the lower portion of the body portion 10. The cup C is housed in the body 10.
As shown in FIG. 1, the body portion 10 is formed by bending one wall plate 11 into a substantially cylindrical shape and bonding both ends (left and right ends) of the wall plate 11 in the longitudinal direction.

As shown in FIG. 4, the blank sheet S1 of the wall plate 11 is a rectangular flat plate extending linearly in one direction. The blank sheet S1 is a single-sided corrugated cardboard in which a core 52 is attached to the inner surface (one side) of one liner 51.
A plurality of flutes 53 extending in a direction orthogonal to the longitudinal direction (circumferential direction) of the blank sheet S1 (the lateral direction of the blank sheet S1) are arranged side by side in the core 52. That is, the core 52 is formed with a corrugated uneven surface continuous in the longitudinal direction of the blank sheet S1.
Each flute 53 of the single-sided corrugated cardboard is exposed on the inner surface of the wall plate 11, and the liner 51 of the single-sided corrugated cardboard is exposed on the outer surface of the wall plate 11.

As shown in FIG. 1, the body portion 10 is formed with a peripheral wall portion 12 in which the wall plate 11 is curved in a substantially cylindrical shape, and a bonding portion 13 in which both ends of the wall plate 11 are bonded together. .. The peripheral wall portion 12 is curved along the outer peripheral edge portion of the bottom plate 20 described later (see FIG. 3).

In the reference example , the peripheral wall portion 12 is formed by bending both sides of the wall plate 11 with the central portion in the longitudinal direction of the wall plate 11 as a base point. The central portion of the wall plate 11 in the longitudinal direction is arranged at the front end portion of the peripheral wall portion 12.

The bonding portion 13 is a portion where the inner surfaces of both ends of the wall plate 11 in the longitudinal direction are bonded to each other. The inner surfaces of both ends of the wall plate 11 are adhesive surfaces provided with adhesive means such as adhesive tape and adhesive, and the inner surface of one end of the wall plate 11 is adhered to the inner surface of the other end.
The bonding portion 13 projects rearward from the rear end portion of the peripheral wall portion 12. The bonding portion 13 is a rectangular flat plate extending in the vertical direction. A central portion of the wall plate 11 in the longitudinal direction is arranged in front of the bonding portion 13.

In the bonding portion 13, as shown in FIG. 3, the cores 52 at both ends of the wall plate 11 are engaged with each other. Specifically, each flute 53 at one end of the wall plate 11 and each flute 53 at the other end of the wall plate 11 are meshed with each other. That is, each flute 53 at the other end is inserted between the flutes 53 at one end of the wall plate 11. In this way, the uneven surfaces formed on the inner surfaces of both ends of the wall plate 11 are combined.

As shown in FIG. 4, handle holes 13a and 13a are formed at both ends of the wall plate 11. As shown in FIG. 1, when both ends of the wall plate 11 are bonded together, the two hand hook holes 13a and 13a communicate with each other.
As described above, the bonding portion 13 of the reference example is formed with the handle holes 13a and 13a penetrating in the left-right direction, and the handle 30 is formed by the bonding portion 13. The handle 30 is a portion to be gripped by hand when holding the container holder 1.

As shown in FIG. 4, mounting grooves 15 are formed linearly along the longitudinal direction of the blank sheet S1 on the inner surface of the wall plate 11. That is, the mounting groove 15 extends in a direction orthogonal to each flute 53.
The mounting groove 15 is a recess into which the outer peripheral edge portion of the bottom plate 20, which will be described later, is fitted. The groove width (width in the vertical direction) of the mounting groove 15 is formed to be substantially the same as the thickness of the bottom plate 20.
The mounting groove 15 is formed by cutting the core 52 into a constant width in the longitudinal direction. Therefore, the liner 51 is exposed at the bottom of the mounting groove 15.

The mounting groove 15 is formed in the lower part of the wall plate 11, and is arranged at a predetermined distance from the lower edge portion of the wall plate 11.
Although the distance between the mounting groove 15 and the lower edge portion of the wall plate 11 is not limited, the band-shaped core 52 between the mounting groove 15 and the lower edge portion of the wall plate 11 is relative to the liner 51. It is set so that a sufficient adhesive area can be secured.

The blank sheet S2 of the bottom plate 20 is a substantially circular flat plate. The blank sheet S2 is a single-sided corrugated cardboard having a core 52 attached to the upper surface of the liner 51.
Each flute 53 of the single-sided corrugated cardboard is exposed on the upper surface of the bottom plate 20, and the liner 51 of the single-sided corrugated cardboard is exposed on the lower surface of the bottom plate 20.
A plurality of flutes 53 extending in the front-rear direction are arranged side by side on the core 52. That is, the core 52 is formed with a concavo-convex surface having a corrugation continuous in the left-right direction.

As shown in FIG. 3, the front half of the bottom plate 20 is formed in a semicircular shape. Further, a semicircular portion and a protruding portion 21 protruding from the rear end portion of the semicircular portion toward the bonding portion 13 side (rear) are formed in the rear half of the bottom plate 20 (FIG. 4).

The width of the protruding portion 21 in the left-right direction is gradually reduced toward the bonded portion 13. The protruding portion 21 is a substantially triangular region having an end portion on the bonding portion 13 side as an apex. The left and right edges of the protrusion 21 are curved in an arc shape so as to have a concave shape toward the inside (see FIG. 4).

As shown in FIG. 1, the bottom plate 20 is fitted in the lower part of the body portion 10. Further, the outer peripheral edge portion of the bottom plate 20 is fitted into the mounting groove 15 of the wall plate 11. As a result, the bottom plate 20 is positioned above the lower end of the body 10.

When assembling the container holder 1 of the reference example , first, as shown in FIG. 4, the front end portion of the bottom plate 20 (blank sheet S2) is fitted into the central portion of the mounting groove 15 of the wall plate 11 (blank sheet S1).
If a mark indicating the central portion of the mounting groove 15 is printed on the inner surface of the wall plate 11 and a mark indicating the front end portion is printed on the bottom plate 20, the bottom plate 20 can be easily assembled to the mounting groove 15.

Then, as shown in FIG. 3, the wall plate 11 is curved in a tubular shape along the outer edge of the bottom plate 20 so that the core 52 side of the single-sided corrugated cardboard is on the inside. As a result, the entire outer edge portion of the bottom plate 20 is fitted into the mounting groove 15.
Further, when the wall plate 11 is curved along both edges of the protruding portion 21 of the bottom plate 20, both ends of the wall plate 11 overlap each other.

Further, as shown in FIG. 1, the inner surfaces of both end portions of the wall plate 11 are bonded to each other to form the bonded portion 13. At this time, the flutes 53 at both ends of the wall plate 11 are engaged with each other (see FIG. 3). Then, the handle 30 is formed on the body portion 10 by the bonding portion 13 of the wall plate 11.
In this way, the container holder 1 including the body portion 10 and the bottom plate 20 can be easily assembled.

When using the container holder 1 of the reference example , as shown in FIG. 2, the cup C is inserted into the body portion 10 through the opening on the upper side of the body portion 10. In the reference example , the heights of the body portion 10 and the bottom plate 20 are set so that the upper end portion of the cup C projects upward from the upper edge portion of the body portion 10.
When the cup C is housed in the body portion 10, the tops of the flutes 53 of the wall plate 11 come into contact with the outer peripheral surface of the cup C. Further, the top of each flute 53 (see FIG. 4) of the bottom plate 20 is in contact with the lower surface of the cup C.

In the container holder 1 as described above, as shown in FIG. 2, when the cup C is housed in the body portion 10, the outer peripheral surface and the lower surface of the cup C are covered with the wall plate 11 and the bottom plate 20. Further, an air layer is formed on the outer periphery and the lower side of the cup C by the internal space of each flute 53 of the wall plate 11 and the bottom plate 20 and the space between the adjacent flutes 53 and 53.
Therefore, in the container holder 1 of the reference example , the single-sided corrugated cardboard can be used to reduce the manufacturing cost and improve the cold and heat retention of the cup C.

The graph of FIG. 5 shows the test results of the cold insulation effect of the container holder 1 of the reference example. The temperature changes of the container holder 1 of the reference example containing the cup C, the cup C alone, and the cup C housed in the body 10 (the configuration without the bottom plate 20) were compared. With each of the above-mentioned measurement targets standing on a table, the temperature change of the beverage in the cup C in the room where the room temperature was 28 degrees was measured. In the configuration in which the body portion 10 is housed in the cup C, the lower end portion of the body portion 10 is lifted from the table by the height from the lower end portion of the body portion 10 to the bottom plate 20 in the container holder 1 of the reference example. It is standing still.
As a result, when one hour has passed, the temperature of the beverage in the cup C housed in the container holder 1 becomes about 5 degrees lower than the temperature of the beverage in the cup C alone. Further, when one hour has passed, the temperature of the beverage in the cup C housed in the container holder 1 becomes about 3 degrees lower than the temperature of the beverage in the cup C housed in the body 10.
From this, it was found that the container holder 1 of the reference example is excellent in the cold insulation property of the cup C.

Further, in the container holder 1 of the reference example , as shown in FIG. 2, the bottom plate 20 is positioned above the lower end portion of the body portion 10, and when the container holder 1 is placed on the table, the bottom plate 20 is positioned. Since a space is formed between the container and the mounting surface, it is possible to improve the cold and heat retention of the lower part of the cup C.

The container holder 1 of the reference example can be easily assembled using the blank sheets S1 and S2 shown in FIG.
When assembling the body portion 10, as shown in FIG. 3, both ends of the wall plate 11 can be smoothly overlapped while the wall plate 11 is gently curved along the edge of the protruding portion 21 of the bottom plate 20. ..

Further, when both ends of the wall plate 11 are overlapped with each other, the flutes 53 of the cores 52 and 52 at both ends of the wall plate 11 are engaged with each other, and both ends of the wall plate 11 are firmly connected.
As a result, the strength of the bonded portion 13 of the body portion 10 can be increased. Then, as shown in FIG. 2, since the strength of the handle 30 formed on the bonding portion 13 can be increased, the container holder 1 can be held stably.

Further, as shown in FIG. 3, since each flute 53 at the other end is inserted between the flutes 53 at one end of the wall plate 11, the thickness of the bonded portion 13 can be reduced.

Although the reference example of the present invention has been described above, the present invention is not limited to the above reference example and can be appropriately modified without departing from the spirit of the reference example.
In the container holder 1 of the reference example , as shown in FIG. 1, the bonding portion 13 is formed in a rectangular shape, but the shape and size of the bonding portion 13 are not limited.
For example, as shown in FIG. 6A, a configuration in which an uneven portion 13b is formed on the inner peripheral edge portion of the handle hole 13a, or as shown in FIG. 6B, two upper and lower handle holes 13a are formed in the bonding portion 13. The bonded portion 13 can be formed in consideration of the ease of gripping and the design of the handle 30, such as the configuration in which the handles 13a are formed.
Further, as shown in FIG. 6C, the bonding portion 13 may be formed small and the uneven portion 13c may be formed on the side edge portion of the bonding portion 13. Further, it is not necessary to form the handle 30 on the bonding portion 13.

In the container holder 1 of the reference example , as shown in FIG. 4, the bottom plate 20 is formed of single-sided corrugated cardboard, but the material of the bottom plate 20 is not limited, and corrugated cardboard or cardboard with liners arranged on both sides. May be used.

In the container holder 1 of the reference example , the wall plate 11 and the bottom plate 20 are formed separately, but the end portion of the bottom plate 20 may be connected to the central portion of the lower edge portion of the wall plate 11. For example, as shown in FIG. 7, when the wall plate 11 and the bottom plate 20 are cut out from one single-sided corrugated cardboard sheet, the liner 51 is left in a band shape between the wall plate 11 and the bottom plate 20. In this configuration, the bottom plate 20 can be attached to the wall plate 11 by the band portion 55 connected to the wall plate 11 and the bottom plate 20.

As shown in FIG. 8, in the embodiment of the present invention, the convex portion 16 in which the core 52 is not cut is left in the mounting groove 15, and the concave portion 26 formed in the front end portion of the outer peripheral edge portion of the bottom plate 20 is mounted. By fitting the groove 15 into the convex portion 16, the bottom plate 20 can be positioned in the circumferential direction with respect to the body portion 10 (see FIG. 1).

In the container holder 1 of the reference example , the mounting groove 15 is formed from one edge portion in the longitudinal direction of the wall plate 11 to the other edge portion, but the mounting groove 15 is formed at least in the region of the peripheral wall portion 12. It suffices if it is done.

In the container holder 1 of the reference example , the height and width of the flute 53 of the core 52 are not limited, but in consideration of cold insulation and heat retention, the width-to-height ratio of the flute 53 is 1: 1. It is preferably 0.73 or 1: 0.5. Further, the width of the flute 53 is preferably 4 to 8 mm, and the height is preferably 2 to 6 mm.
The thickness of the liner 51 and the core 52 is not limited, but the thickness of the liner 51 is 0.2 to 0.5 mm and the thickness of the core 52 is 0.2 to 0.5 mm in consideration of cold insulation and heat retention. It is preferably 0.1 to 0.5 mm. Further, the thickness of the single-sided corrugated cardboard is preferably 2 to 8 mm.

In the reference example , each flute 53 extends in a direction orthogonal to the longitudinal direction (circumferential direction) of the wall plate 11, but each flute 53 may be inclined with respect to the longitudinal direction (circumferential direction) of the wall plate 11. .. When each flute 53 is extended in a direction orthogonal to the longitudinal direction (circumferential direction) of the wall plate 11 as in the reference example, the wall plate 11 is likely to be curved into a tubular shape.

When a white liner is used for the single-sided corrugated cardboard in the container holder 1 of the reference example, the pattern and the product name can be clearly printed on the outer surface of the body portion 10. Further, the wall plate 11 and the bottom plate 20 may be waterproofed.

In the container holder 1 of the reference example , as shown in FIG. 2, the cup C for drinking water is housed in the body 10, but the bottomed tubular container housed in the body 10 is limited. It's not a thing.
