Description

[Detailed description of the invention] (Industrial application field) The invention is applicable to, for example, bottles, cans, etc.
This invention relates to container cold-proofing paper used for box-shaped synthetic resin containers for storing products such as small boxes.

(Prior art) Generally, this type of container has an opening at the top and a hole in the side wall for handling, so rainwater can be removed during transportation in cold regions or storage in a warehouse. , snow, cold wind, etc. may directly hit the products inside the container. For this reason, kraft paper,
Cold protection paper made of paper materials such as cardboard and paperboard, or
Cold protection sheets made of synthetic resin sheets such as PSP (polystyrene paper) are fitted over the openings of containers to prevent rainwater, snow, cold wind, etc. from directly hitting the products, thereby preventing contamination, freezing, and damage to the products. We are trying to prevent this and maintain the quality of our products.

(Problem to be solved by the invention) By the way, in the conventional technology, cold protection paper made of paper material is made by simply punching out cardboard into a rectangular shape and integrally forming the top part and the flap part, so it is difficult to avoid wind pressure and There is a problem in that it easily comes off from the container due to vibrations etc. during transportation.

On the other hand, a synthetic resin cold protection sheet is made up of a top surface, a flap, and a protrusion that protrudes from the flap and engages with the handle hole of the container, and has heat retention and water resistance. It has the advantage that it has excellent durability and does not easily come off from the container due to the engagement force of the protrusion, and is often used in place of conventional cold-proof paper.

However, cold weather sheets are disposable, and large amounts of cold weather sheets must be discarded every day at retail stores, but because they are made of synthetic resin, they must be disposed of as industrial waste. First, there is the problem of placing a heavy burden on retailers. Another disadvantage is that printing multicolor advertisements on synthetic resin sheets is technically expensive.

The present invention has been devised in view of the problems of the prior art described above, and it is an object of the present invention to provide a cold-proofing paper for containers that is made of paper that is easy to dispose of and that does not easily separate from the container.

(Means for Solving the Problems) The cold protection paper for containers according to the present invention configured to solve the above-mentioned problems has a rectangular top portion that is fitted into the container so as to cover the opening of the container. a flap portion integrally protruding from at least one pair of opposing side edges of the top surface portion; a pair of notches formed from each flap portion to the top surface portion; and a flap portion configured to connect the opposite ends of the pair of notches. A pair of opposing fold line portions formed parallel to each other are located on the top surface portion and the flap portion.
A band-shaped rising portion disposed from the top surface portion to each flap portion, and a band-shaped rising portion disposed between the top surface portion and each flap portion except for the band-shaped rising portion such that each flap portion can be bent with respect to the top surface portion. a pair of flap folding lines formed at the boundaries of the flap, and a pair of flap folding lines formed at the boundaries of the flap, and a pair of flap folding lines formed at the boundaries of the flap, and a pair of flap folding lines formed at the boundaries of the flap. and a rising fold line portion formed on the band-shaped rising portion and located closer to each flap than the flap fold line portion.

(Function) By bending the flap portion, a band-shaped rising portion protrudes from the outside of the flap portion, and the band-shaped rising portion engages with the handle hole portion of the container.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings.

First, FIGS. 1 to 4 show a first embodiment of the present invention. In the figure, 1 is, for example, a beer bottle A
The container 1 has a rectangular opening at the top formed by opposing front and rear walls 1A, 1B, left and right walls 1C, 1D, and a bottom (not shown). It is formed in the shape of a box with a bottom. Reference numerals 3 and 3 indicate handle holes provided in the front wall portion 1A and the rear wall portion 1B (however, the rear wall portion 1B side is not shown);
is formed into a horizontally long rectangular shape by the mouth edge 3A. On the other hand, 4 and 4 are the left wall portion 1C and the right wall portion 1D.
Other hand holes provided in the left wall section 1
(C side is not shown), and each hand hole 4 is also formed into a horizontally long rectangular shape by the mouth edge 4A. Further, reinforcing vertical ribs 5, 5, . . . are formed protruding from the inner surface of each wall portion 1A, 1B, 1C, 1D, located on both sides of the hand hole portions 3, 4 in the lateral direction ( (See Figure 4).

Next, reference numeral 11 indicates a cold-proofing paper for a container (hereinafter referred to as cold-proofing paper) of this embodiment which is fitted into the container 1, and the cold-proofing paper 11 is made by punching out a piece of cardboard. Reference numeral 12 denotes a top portion that constitutes the cold protection paper 11 and is fitted into the opening 2 of the container 1 so as to close it.
It is formed into a rectangular shape slightly smaller than the opening 2 by the flap folding line portions 20 and the top side forming portions 13, 13 at right angles.

Reference numerals 14 and 14 designate a pair of flap portions that protrude from the top surface portion 12 in the vertical direction of the plane of the paper in FIG. Part 1
5, and a pair of flap side forming portions 16, 16 formed to connect the flap tip forming portion 15 and both ends of the flap folding line portion, forming a horizontally long rectangular shape. Each flap part 14 has a handle hole 17 formed in the longitudinal direction by a notch 17A and a folding line part 17B, located approximately in the center, and also near both ends of the flap part 14. A pair of rib-fitting notches 18, 18 are formed at the position from the flap tip forming portion 15 toward the flap folding line portion 20.

Reference numerals 19, 19, 19, 19 are a pair of band-shaped rising parts located on both sides of the handle hole 17 in the length direction and provided from the top surface part 12 to each flap part 14, and each of the band-shaped rising parts 19 A pair of notches 19A, 19A formed in parallel from the surface portion 12 to the flap portion 14, and a pair of notches 19A, 19A located in the top surface portion 12 and the flap portion 14, and provided to connect opposite ends of the pair of notches 19A, 19A. Fold line part 1
9B and 19C form a belt shape with a predetermined width, and the facing fold line part 19B on one side is mountain-folded, and the facing fold line part 19C on the other side is designed to be valley-folded.

Next, 20, 20 are a pair of folded flaps formed on the boundary between the top surface section 12 and the flap section 14 so that each flap section 14 can be bent approximately 90 degrees downward relative to the top surface section 12. At the line part,
The flap fold line portions 20 are arranged in a direction perpendicular to the band-like rising portions 19, except for the portions of the band-like rising portions 19.

On the other hand, 21, 21, 21, 21 are located on the flap part 14 side of each flap folding line part 20 and are formed in each of the band-shaped rising parts 19 in parallel with the flap folding line part 20, respectively. In the line portion, each rising fold line portion 21 is connected to the flap portion 1.
When 4 is folded downward, it is interlocked and folds into a mountain.

The cold protection paper 11 of this embodiment has the above-described structure, and is manufactured by punching and embossing a cardboard base paper. Therefore, the function of the cold protection paper 11 will be explained next.

First, in order to fit the cold protection paper 11 into the opening 2 of the container 1, each flap part 14 is bent below the top part 12 via each flap folding line part 20,
Each flap part 14 can be inserted into the container 1 along each inner surface of the front wall part 1A and the rear wall part 1B.

By the way, since the band-shaped rising portion 19 provided from the top surface portion 12 to each flap portion 14 has the other side opposing fold line portion 19C formed on the flap portion 14 side, the flap portion 14 is formed around the flap portion fold line portion 20. When folded, the opposite folding line portion 19C on the other side also extends a distance L ₁ from the flap folding line portion 20.
Try to rotate with a radius of . At this time, since the band-shaped rising portion 19 is separated from the top surface portion 12 and the flap portion 14 by the notches 19A, 19A on both sides, the band-shaped rising portion 19 itself is also separated by a distance L from the opposite fold line portion 19B on one side. Try to rotate with a radius of ₂ .

However, since the distance L ₂ between the one side opposing fold line section 19B and the other side opposing fold line section 19C is longer than the distance L ₁ between the flap fold line section 20 and the other side opposing fold line section 19C. , the other side opposing fold line portion 19C
If the flap part 14 attempts to rotate together with the flap part 14, the difference between the distances _L1 and _L2 must be absorbed. Therefore, the band-shaped rising portion 19 is bent in a dogleg shape with the rising fold line portion 21 as the apex, and the band-shaped rising portion 19 is bent at the top surface portion 12.
Flap portion 14 bent at nearly 90 degrees
It will be in a state where it protrudes outside.

In this way, when the cold protection paper 11 with the band-shaped rising portions 19 protruding from the outside of the flap portion 14 is fitted so as to be slightly pushed into the container 1, each band-shaped rising portion 19 will fit into the handle hole 3 of the container 1. ，
It will engage with the upper side of the mouth rim 3A of No. 3 (the fourth
(see figure). Moreover, as shown in the figure, the tip side of the flap part 14 is inserted into the gap between the front wall part 1A (rear wall part 1B) of the container 1 and the beer bottle A, and its movement is restricted. The band-shaped rising portion 19 also does not easily come off from the handle hole 3.

On the other hand, when removing the cold protection paper 11 from the container 1, insert your finger into the handle hole 17 and lift the flap part 14 upwards.
is bent due to the flexibility of the cardboard and can be easily removed from the handle hole 3.

Alternatively, the cold-proof paper 11 may be removed by inserting fingers into the container 1 through the handle holes 4, 4 of the left wall part 1C and the right wall part 1D and pushing up the top surface part 12 of the cold-proof paper 11. good.

Next, FIG. 5 shows a second embodiment of the present invention.
Note that the same components as those of the first embodiment described above are given the same reference numerals, and their explanations will be omitted.

However, the feature of this embodiment is that flap portions 33 are provided on a pair of side edges of the rectangular top surface portion 32 constituting the cold-protecting paper 31 for containers, respectively facing the front wall portion 1A and the rear wall portion 1B of the container 1. ,33
(one not shown) at the flap fold line portions 20, 2
0, and on the other pair of side edges, side flap portions 34, 34 facing the left wall portion 1C and right wall portion 1D of the container 1, respectively, are connected via flap fold line portions 35, 35. However, each side flap portion 34 is provided with a hole 17 for a handle.

This embodiment is constructed as described above, and the cold protection paper 31 is fitted and locked to the container 1.
There is no substantial difference in the operation itself from that of the first embodiment. However, since the flaps 33, 33 and 34, 34 are provided on the four sides of the top surface 32 to surround the upper four sides of the opening 2 of the container 1, the flaps 33, 33 and 34, 34 are provided above the opening 2 and the handle holes 3, 3, 34. It is possible to reliably prevent rainwater, snow, dust, etc. from entering the container 1 from 4, 4, and the container 1
Prevents dirt and damage to the products inside.

In each of the embodiments, a pair of strip-like rising portions 19, 19 is provided from the top surface portions 12, 32 to each of the flap portions 14, 14, 33, 33. You may provide one each. Moreover, each flap part 33, 33,
A total of four strip-shaped rising portions may be provided, one each extending over the sections 34 and 34. Furthermore, the handle hole 17 is connected to the side flap portions 34, 34.
However, the present invention is not limited to this, and may also be provided on the flap portions 33, 33 side.

Furthermore, each of the examples includes cold protection paper for containers 11,
Although cardboard has been taken as an example of the material of 31, various other materials such as kraft paper, paperboard, etc., which are strong, flexible, and flammable can be used.

(Effects of the invention) The present invention is as described in detail above, and includes a band-like rising part that rises outward when the flap part is folded from the top surface part, and the band-like rising part is used to handle the container. Because it is configured to engage with the hole, it can prevent the product from coming off the container due to wind pressure or vibration during transportation, which is the case with conventional cold-protecting paper made of paper materials, and prevents products from getting dirty or being damaged. It is possible to maintain the quality of the product.

Furthermore, since the synthetic resin cold protection sheet used in the prior art can be abolished, the problem and burden of disposing of industrial waste after use can be completely eliminated.

Moreover, in order to display advertisements on synthetic resin cold weather sheets using conventional technology, a mold is required, and multicolor printing increases the cost, but with the present invention, it can be printed on paper, so it is inexpensive. It is now possible to display beautiful advertisements at a low printing cost, and cold weather paper can be used as an advertising medium.
