A heat insulating container in which a heat insulating space is formed between the inner surface of the side wall 11 of the tubular body 10 and the outer surface of the side wall 21 of the body portion of the paper cup body 20 in combination with the paper cup body 20 in which the ribs 25 are formed. . Then, the side wall 11 of the tubular body 10
The cut piece 13 is provided on the
By cutting out, it is possible to visually recognize information such as lottery, points, quiz answers, etc. printed on the back surface of the cut piece 13 or printed on the side wall 21 of the paper cup body 20. In this example, the side wall 11 of the tubular body 10 is provided with the cut-off piece 13 at one place, but it may be provided at a plurality of places.

The formation of the heat insulation space of the heat insulation container 1 with the hidden picture according to the present invention is performed by the horizontal ribs 24 provided on the side wall 21 of the paper cup body 20 and protruding downward and the lower portion of the tubular body 10 as shown in FIG. It is realized by the inward curl 12 formed in the. However, in the left-standing state, the side wall 11 of the tubular body 10 and the horizontal rib 24 protruding outward of the side wall 21 of the paper cup body 20 do not necessarily have to be in contact with each other.
Further, the main role of the horizontal rib 24 is to reinforce the side wall 21 of the paper cup body 20, and it is not always necessary in a container having a small internal volume. The role of the horizontal ribs 25 is to give an indication of the proper amount of hot water to be poured. In this example, the inward curl 12 is formed at the lower end of the tubular body 10 and the horizontal rib 24 is provided on the side wall 21 of the paper cup body 20, but these are not always necessary, but the paper cup body 2
By providing a space between the side wall 21 of 0 and the side wall 11 of the tubular body 10, the heat insulating effect is enhanced and the cut piece 13 is easily cut.

FIG. 2 is a blank development view of the cylindrical body of the heat insulation container 1 with a hidden picture according to the present invention. As shown in FIG. 2, the blank 10A of the tubular body 10 is made by punching a paperboard in a fan shape. The left and right ends of the blank 10A are the body sticking portion N, and the lower end portion thereof is the curl molding portion C of the inward curl 12. ing. The portion other than the curl molding portion C is a portion forming the side wall 11 of the tubular body 10. In the cylindrical blank 10A, the body attachment portions N are bonded to each other to form the inverted truncated cone-shaped cylindrical body 10. The blank 10A of the cylindrical body 10 is divided by the cut line 14. The cut-out piece 13 is provided by punching. Although the shape of the cut-out piece 13 is circular in this example, it may be a semi-circle, a triangle, a quadrangle, or a modification thereof, and is not particularly limited.

FIG. 3 and FIG. 4 are enlarged explanatory views of the blank 13 of the cutout piece 13. FIG. 3A shows an example of the cut piece 13, and the cut piece 13A is
It is provided on a side wall 11 of the cylindrical blank 10A by a score line 14. Also, in the middle of the break line 14,
The connecting portion 16 is formed. The connecting portion 16 is for holding the cut piece 13A on the side wall 11 until just before the last cut piece 13A is used, when the blank 10A of the cylindrical body is formed into the cylindrical body 10 and is incorporated in the paper cup body 20. It is preferable that the cut piece 13A has a width of about 0.3 to 1.0 mm (when the thickness of the paperboard is 0.2 to 0.5 mm) which is destroyed by a slight finger force when the cut piece 13A is used. . Generally, when tearing and cutting the paper, the pulling force in the grain direction requires more force than the pulling direction perpendicular to the grain. Therefore, this connecting portion 1
When a plurality of 6 are provided on one side of the cut line 14, the width of the connection portion 16 becomes larger as the width becomes closer to the direction of the grain shown by the arrow, and the cutting resistance of the connection portion 16 is averaged. It is preferable that the

As shown in FIG. 3B, a cutout 17 is formed at one edge of the cutout piece 13A. The notch 17 is used as a grip for cutting out the cut-out piece 13A when the cut-out piece 13 is formed, and may have a size such that a fingertip or a nail can be inserted therein, and the cutout 17 is provided at one edge of the cut-out piece 13A. Is preferred.

Further, as shown in FIG. 3C, the small bent portion 18 can be provided by the small broken line 18a instead of providing the notch 17 at one edge of the cutout piece 13A.
The small bent portion 18 is such that the lower portion of the cut-out piece 13A is easily bent, and the cut-out piece 13A can be pulled out as a whole by pulling it out.

The small broken line 18a, the break line 14,
Since all of the connecting piece 16 and the notch 17 can be formed simultaneously with the blanking process of the blank 10A, these processes do not cause a cost increase.
Further, most of the blank 10A has a blank 10A
However, the printing effect or the design effect is not significantly hindered by the processing of the cut pieces 13A.

FIG. 4-a shows another example of the cut-out piece 13, wherein the cut-out piece 13B is a cylindrical blank 10A.
It is divided by a score line 14 and a fold line 15 on the outer circumference of, and the entire circumference is not cut line 14 but a part is provided with a fold line 15 and the cut piece 13B is not completely cut off but is folded back to the outside by the fold line 15. It is possible.

As with the cut-out piece 13A, as shown in FIG.
As shown in b, a cutout 17 can be provided at one edge of the cut piece 13B, and a small bent portion 18 can be provided at one edge of the cut piece 13B as shown in FIG. 4-c.

Since all of the above-mentioned polygonal line 15, small polygonal line 18a, cut line 14, connecting piece 16 and notch 17 can be formed simultaneously with the blanking process of the blank 10A, these processes are performed. It does not cause cost increase.

As a material of the paper cup body 20 constituting the heat insulation container 1 with a hidden picture according to the present invention, a laminated body in which a polyolefin resin is laminated on at least the inner surface of paper as a base material layer is used. A cup base paper is mainly used as the paper, and its basis weight is about 150 to 450 g / m ² .
On the inner surface of the cup base paper, a polyolefin resin layer such as a low density polyethylene resin, a medium density polyethylene resin, a high density polyethylene resin, and a linear low density polyethylene resin is extrusion-coated in a range of 20 to 80 μm. This polyolefin resin layer not only prevents the contents from penetrating into the paperboard and improves the suitability for protecting the contents, but also improves the cup moldability at the bottom portion, curl portion, and body sticking portion, and improves the cover material (not shown). This also brings about the effect of improving the sealing property by heat sealing in the top curl portion. The paper cup body 20 may be a plastic cup whose main material is plastic.

On the other hand, as the material of the tubular body 10, the basis weight 2
It is possible to use cardboard, coated ball-based cardboard, etc. having a weight of 0 to 450 g / m ² . If the basis weight is less than this limit, the rigidity of the tubular body 10 becomes too low, and the bending becomes too large especially at high heat to lose sufficient heat insulating property. If it exceeds the limit, the rigidity becomes high. , Inward curl 1
No. 2 is not preferable because the workability is deteriorated and the material cost is increased.

Also, a heat insulating container 1 with a hidden picture according to the present invention
Then, when the food of the content is distributed in a chilled or frozen state, it is preferable to have water resistance. Therefore, polyethylene resin on the front surface and / or the back surface,
A polypropylene resin, a polyethylene terephthalate resin, etc. can be laminated. Further, a water resistant double coated ball which has been made water resistant at the paper making stage may be used.

Next, a method of manufacturing the heat insulation container 1 with the hidden picture according to the present invention will be described. First, a print such as a design or a display is printed on the surface of a laminate mainly composed of a paperboard for the tubular body 10 having a printing layer on the surface or in the middle, and a lottery is drawn on the back surface, particularly on the back surface of the cut piece 13. Print hidden pictures of information such as points and quiz answers. Next, the blank 10A of the tubular body 10 is created by punching in a fan shape and simultaneously processing the cut-out piece 13 as described above.

Since the front surface and the back surface of the tubular body 10, especially the back surface of the cut-out piece 13 can be preprinted on the board in a flat state before the blank 10A is punched, the degree of freedom of printing is high and the offset Not only known printing such as gravure and flexo, but also post-printing processing such as various overcoating, foil stamping and embossing can be freely performed. After printing, the cut-out piece 13 is processed as described above, but this processing does not hinder the flatness, and the function of information such as the cosmetic effect by printing, lottery, points, and quiz answers. Is kept as it is.

On the other hand, a cup-forming machine is used to form an inverted truncated cone-shaped body portion 21 from a blank 20A (not shown) for the paper cup body 20, and the lower portion of the body portion 21 is wound with a bottom plate 22 to form a bottom portion. Then, the outward curl 23 is formed at the upper open end, and then the horizontal ribs 24 and 25 protruding outward or inward are formed at a predetermined level of the body to manufacture the paper cup body 20. It is also possible to print a hidden picture of information such as a lottery, a score, a quiz answer, etc. on the body portion 21 of the paper cup main body 20 as well, particularly at a position visible when the cut-out piece 13 of the tubular body 10 is cut out.

The ribs 24 protruding outward can be processed in-line or off-line on the cup molding machine. That is, by fitting the molded paper cup body 20 into the cavity in which the horizontal ribs 24 are cut in a groove shape in advance and rotating the roller cup from the inside of the cup to the outside with the expander in the groove, the outside It is possible to form a rib that protrudes inward. In this case, the paper cup body 20 that has been processed from the cavity must be finally pulled out, but the horizontal rib 24 having a gentle upper slope is easier to pull out than the sharp one, and is superior in workability. Also,
The rib 24 can also be formed by drawing using a male and female die. The ribs 25 protruding inward are processed by fitting the molded paper cup main body into a mandrel whose ribs 25 are cut in a groove shape in advance, and rotating the rollers toward the inside from the outside of the cup in the groove while rotating. It can be formed by pressing firmly.

On the other hand, an inverted frustoconical tubular body 10 is formed from the tubular blank 10A, and an inward curl portion 12 is formed in the lower part of the tubular body 10 and stacked. Finally, the cylindrical body 10 is attached to the molded paper cup body 20 while being adhered at any point where they abut each other, so that the heat insulation container 1 with a hidden picture according to the present invention is obtained. Completed insulation container with hidden picture 1 according to the present invention
Can be stacked and supplied to users.

FIG. 5 is a plan view for explaining the state when the heat insulation container with a hidden picture 1 according to the present invention is actually used.
As a hidden picture of the insulated container 1 with a hidden picture according to the present invention,
In order to visually recognize information such as lottery, points, quiz answers, etc., first, insert the cut-out piece 13 into the notch 17 shown in FIG. In the case of the cut piece 13 shown in the drawing, first, the small bent portion 18 of the cut piece 13 is folded back along the small broken line 18a to form a knob piece, and then the knob piece is sandwiched by fingers and lifted upward. As shown in 5-a, the cut piece 13 can be cut using this as a starting point. When the broken line 15 is provided in a part of the break line 14, it can be folded back at the broken line 15 without being completely cut off, as shown in FIG. In the heat insulating container 1 with a hidden picture according to the present invention, when there is a space between the side wall 21 of the paper cup body 20 and the side wall 11 of the tubular body 10, the cut piece 13 can be easily raised with a weak force.
By cutting or folding back the cut piece 13, information such as lottery, points, quiz answers, etc. printed on the back of the cut piece 13 can be visually recognized.
