Description

  Inside the flat box-shaped envelope, the original three-dimensional object is stored as a flat shape by extending the rubber spring, and when the envelope is opened, the rubber spring returns to its original position. The present invention relates to an envelope set that jumps out in a three-dimensional shape.

Traditionally, toys called surprise boxes have been popular. This is because people tend to like items that are naturally cute and have intentions.
Recently, pop-out picture books have become popular. Conventionally, many greeting cards have pictures and letters printed on flat cardboard, and a message can be written in the margin, but as proposed in Patent Document 1, an envelope that gives an impression similar to a surprise box I'm starting to see sets.

JP 2006-219180 A

  The envelope set described in Patent Document 1 is surprising and impressive for the recipient. However, the planar shape is merely made to appear as if it is a three-dimensional shape by means of coloring. However, instead of using such an optical illusion, if a solid actually pops out of a flat envelope, it can give a stronger impression to the other party.

On the other hand, at the end of the year, various companies distribute free desk calendars in envelopes to customers. However, since they all have a similar appearance, there is nothing to appeal to customers. If a three-dimensional calendar pops out when you open an envelope, it can be differentiated from other companies' calendars due to its strangeness.
Also, although many Christmas and birthday cards resemble picture books that pop out, solid objects do not pop out directly from envelopes. If a three-dimensional card pops out when you try to remove it from an envelope, it will be fun and inspiring.
In view of such a point, an object of the present invention is to provide an envelope set in which a solid that can be used for applications such as a desktop calendar and a greeting card is popped out.

In order to achieve the above object, the envelope set of the present invention is a flat box-shaped envelope and an envelope set made of a container that can be transformed into either a planar shape or a three-dimensional shape, The stored object is stored in the envelope in a state in which a rubber spring provided on the inside is stretched to maintain a planar shape, and when the envelope is opened, a force to return to the original length of the rubber spring; In conjunction with this, the object to be stored changes into a three-dimensional shape and jumps out from the opened envelope.
Thereby, an unusual envelope set can be provided.

The envelope is provided with an inner bent piece on one opposite side of a rectangular plane on which the storage object is placed, and provided with an outer bent piece on the other opposite side, and on one of the outer bent pieces. An insertion groove is formed, and an insertion piece to be inserted into this insertion groove is provided on the other of the outer folding pieces, and in order to close the envelope, both inner folding pieces are bent, The folding piece is folded and overlapped, and the insertion piece is configured to be inserted into the insertion groove.
Thereby, an envelope can be prevented from opening carelessly.

The shape of the object to be stored when the rubber spring is not extended is a quadrangular prism, and the rubber spring is stretched between the vicinity of one central portion of one opposing side and the vicinity of the other central portion. A feature is that the expansion and contraction of the rubber spring is adjusted by providing a folding piece that can be folded inside between two adjacent upper and lower sides of the side surface sharing each side.
A side is a side that forms a boundary between side surfaces.
In order to make the folded piece foldable inward, in the embodiment, a valley folding curve is provided at a position that bisects the folded piece in two lines.

The square column may be a cube. This is because the cube is the most easily handled square pole.
Further, an ear piece may be provided continuously on each of the opposing sides, a rubber through hole may be provided in each ear piece, and the rubber spring may be stretched between both rubber through holes. This is because the strength is increased as compared with directly attaching a rubber spring to the side.

  The envelope set that pops out of the present invention may be used for distributing a desktop calendar or as a greeting card set.

Depending on the idea, we can provide envelope sets that can be used in various ways.
If it is used for a calendar or a greeting card, it can give a strong impression to the recipient because of its strangeness and fun.

With reference to the drawings, a pop-out envelope set (hereinafter referred to as “envelope set”) according to a preferred embodiment of the present invention will be described.
As shown in FIG. 1, an envelope set 1 is composed of a flat box-shaped envelope 2 and an object to be stored (hereinafter referred to as “inner box”) 3 stored therein.
When the envelope set 1 is distributed or the like, the inner box 3 is accommodated in the envelope 2 as shown in the lower part of FIG. When the envelope 2 is opened, the inner box 3 jumps out of the envelope 2 as shown in FIG.

  As will be described in detail later, the inner box 3 is provided with a rubber spring, and can be deformed into either a planar shape or a three-dimensional shape by expansion and contraction of the rubber spring. When housed in a flat shape. In the inner box 3, a force that tries to return to the original three-dimensional shape works in conjunction with the force of the extended rubber spring to return to the original length. The force is suppressed and the planar shape is maintained. Here, each of the envelope 2 and the inner box 3 may be made of cardboard, cardboard, or resin, and any material can be used as long as it has a hardness that can realize an envelope from which a stored item pops out.

The envelope 2 is unfolded as shown in FIG. 3 and forms a pair with the upper piece 4, the four gussets 5, the lower piece 6, the opposing pair of side pieces 7, and the lower piece 6. And a lid piece 8. Here, the pair of side pieces 7 corresponds to the inner bent piece of claim 2, and the lower piece 6 and the lid piece 8 correspond to the outer bent piece of claim 2. Further, the upper side 4 is the surface on which the address of the envelope is written, and the lower piece 6 is the back side of the envelope.
An insertion piece 9 is provided at the tip of the lid piece 8, and a pair of insertion end portions 9 a and 9 b are provided on both sides of the insertion piece 9. The lower piece 6 is provided with a pair of insertion grooves 10 (10a, 10b) at positions corresponding to the insertion end portions 9a, 9b.

  In order to store the inner box 3 inside, the inner side of the envelope 2 is unfolded face-up, and the inner box 3 deformed into a planar shape is placed on the upper piece 4. Is folded so as to overlap the inner box 3, and the lower piece 6 is folded so as to overlap the inner box 3 and the side piece 7. Subsequently, the lid piece 8 is bent so as to cover the lower piece 6, and the insertion piece end portions 9a and 9b are inserted into the back side of the lower piece 6 from the insertion grooves 10a and 10b. Thus, since it was set as the structure which inserts the insertion piece 9 in the insertion groove | channel 10, the cover piece 8 opens carelessly and the envelope 2 is not open | released. Thereby, when it is not intended, the inner box 3 accommodated can be prevented from popping out.

When the inner box 3 is not stored in the outer box 2, it has a cubic shape as shown in FIG.
FIG. 5 shows an example in which the inner box 3 is developed when one sheet is used.
In FIG. 5, the broken line means a mountain fold, and the alternate long and short dash line means a valley fold.

The inner box 3 is configured as follows. First, as shown in FIG. 5, fold lines 15a, 15b, 16, 17a, 17b, and 18 are bent on four side surfaces 11 to 14, and adhesive margin 19a is attached to the opposite side surface 14 to form a rectangular tube. To do. Here, the center of the ear piece 20 provided between the fold lines 15 a and 15 b is valley-folded, and the fold lines 15 a and 15 b are used as the overlapping side 15. Similarly, the center of the ear piece 21 provided between the fold lines 17 a and 17 b is valley-folded, and the fold lines 17 a and 17 b are used as the overlapping side 17.
The small triangular piece 22a connected to the upper side of the side surface 11 and the small piece 22b formed on the right triangular shape connected to the upper side of the side surface 14 are joined together by a glue margin 19b to form a folded piece 22. A line segment at the boundary between the small piece 22b and the adhesive margin 19b is bent by a valley fold to form a folding line 26. Other folding pieces 23, 24, 25 and folding lines 27, 28, 29 are formed in the same manner.

  The ear piece 20 connected to the opposite side 15 and the inside of the inner box 3 is provided with a rubber through hole 30 near the center of the side 15, and the ear piece 21 connected to the side 17 and the inside of the inner box 3 A rubber through hole 31 is provided near the center of the side 17. The rubber spring 32 is stretched between the rubber through holes 30 and 31.

Since the folding lines 26 to 29 have valley folds, when the folding pieces 22 to 25 are pushed toward the inside of the inner box 3 with the fingertips, the inner box 3 has a rubber as shown in FIG. The spring 32 extends, the side 16 and the side 18 approach each other, and the bottom shape of the inner box 3 becomes a rhombus.
Further, when each folded piece is pushed inward and the rubber spring 32 is extended, the side surface 11 and the side surface 14 and the side surface 12 and the side surface 13 overlap each other as shown in FIG. It has a rectangular appearance with a long side ratio of 1: 2.

  The inner box 3 in this state is stored in the envelope 2, and the insertion piece end portions 9a and 9b are inserted into the insertion grooves 10a and 10b. Thus, by sealing the envelope 2, the force of the rubber spring 32 trying to return to the original length can be suppressed, and the inner box 3 can be maintained in a planar shape. Thereby, the envelope set 1 which accommodated the inner box 3 in the inside of the envelope 2 is comprised.

  In the above configuration, when the envelope set 1 is used as a calendar, a company name or the like is printed on the front side of the upper piece 4 of the envelope 2 as shown in FIG. A calendar is printed on the side surfaces 11 to 14 of the inner box 3, and the inner box 3 is stored in the envelope 2 and distributed to customers. It is also possible to put a stamp on the upper piece 4 of the envelope 2 and mail it.

When the person who receives this calendar opens the cover piece 8 of the envelope 2, the force to return to the original length of the rubber spring 32 is released, and the planar state shown in FIG. Through such a state, it is deformed into a cubic shape as shown in FIG. Here, if the folding pieces 22 to 25 are not present, the inner box 3 is deformed in conjunction with the contraction of the rubber spring 32. As a result, there is a possibility that the inner box 3 does not become a cube but has a rectangular column shape with a rhombus bottom. However, if four folding pieces 22 to 25 are provided as in this embodiment, these folding pieces serve as stoppers and always return to a cube.
For those who were expecting a flat calendar, the box-shaped solid pops out, so it feels surprising and leaves an impression as an unusual calendar.

The above-described embodiment is merely an example, and various modifications are possible.
The envelope set of the present invention can be used for various purposes other than the use as a desktop calendar. For example, a character or design may be printed on the side of the inner box, a field for writing a handwritten message may be provided and stored in an envelope, and sent to a friend's acquaintance as a Christmas card or birthday card.

  In the above-described embodiment, the rubber spring is provided via two ear pieces. However, both ends of the rubber spring may be fixed with an adhesive or the like in the vicinity of each center of a pair of opposing sides.

Further, the number of inner boxes to be stored in the envelope is not limited to one, and a plurality of inner boxes may be stored so that small dice-shaped boxes continuously pop out.
Furthermore, the shape of the solid protruding from the envelope is not limited to a cube, and variations such as a rectangular column with a rhombus on the bottom are possible.

  The envelope set of the present invention can be adopted by manufacturers that manufacture promotional items such as calendars and greeting cards and stationery items.
