Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a bifold card that can be used as a postcard, and can also be used as various greeting cards such as Christmas cards.

(Prior art) This kind of bi-fold card is closed in a sealed manner, and inside the bi-fold, tickets, thin small items, messages, etc.
It may be sent with other contents.

However, in order to seal this type of bi-fold card, for example, if the entire bi-fold card is laminated with a heat adhesive sheet, when inserting scissors around the outer periphery of the bi-fold card to take out the contents, it is difficult to remove the contents. There is a risk of cutting. Furthermore, if the entire front and back sides of a bifold card are laminated, stamps cannot be affixed directly to the front surface of the card, so it cannot be used as a postcard.

Further, when the outer periphery of the bifold card is fixed with adhesive or staples, the sealing is likely to be incomplete, resulting in inefficiency when producing in large quantities.

(Problems to be solved by the invention) The present invention was created in view of the above points, and can be used as a postcard without the risk of cutting the contents when inserting scissors to take out the contents. Furthermore, it is an object of the present invention to provide a bi-fold card of this type that is securely sealed.

(Means for Solving the Problems) In order to achieve the above object, the bi-fold card of the present invention has one card piece 2 folded onto the other card piece 3, as shown in the embodiment of the figure. In the bi-folded card 1 which is overlapped by folding, one card piece 2
A joint surface 4 is formed along the outer peripheral edge of the card piece 2 to expose the surface of the other card piece 3, which has a larger diameter than the one card piece 2. A large number of engagement holes 5 are formed in a row in the inner part along the outer peripheral edge, and on the upper surface of one card piece 2, there is a hole that is continuous with at least the joining surface 4 and the row of engagement holes 5. The film-like adhesion layer 6 is formed in a polymeric manner.

(Function) In the above-mentioned sealed state, when the content A is inserted into the double-folded interior of the card 1, the content A is deposited on the surface of the other card piece 3 inside the engagement hole 5. The layer 6 prevents the card 1 from moving toward the outer edge. Therefore, when opening the package, even if scissors are inserted over the engagement hole 5 or between the engagement hole 5 and the joint surface 4, there is no risk of cutting the contents.

Further, since the sealing layer 6 is formed continuously on the outer circumferential joint surface 4 and the inner engagement hole 5, sealing is ensured.

(Example) Figures 1 and 2 show the bi-fold card 1 of the present invention.
FIG. 3 shows the second embodiment.

The engagement holes 5 may be arranged in a row along the outer peripheral edge of one of the card pieces 2 out of a large number of round holes as in the first embodiment, or square holes as in the second embodiment. It can be made into various shapes such as , slit shape, star shape, etc.

The adhesive layer 6 may be an adhesive layer such as a coating film or a welding layer such as a thermoplastic film, and may be formed on the entire one side of the bifold card 1 as in the first embodiment. Alternatively, the window 7 can be formed in a part as in the second embodiment. Further, the adhesive layer may be formed on both sides of the bi-fold card 1, but if the adhesive layer 6 is formed on only one side as in the first and second embodiments, the other card Since stamps can be affixed directly to the surface of piece 3 and the addressee can be written directly on it, it can be used as a postcard. Furthermore, it is desirable that the adhering layer 6 be transparent or semi-transparent, but even if it is opaque, the effect will remain the same since the engaging hole 5 will be visible because it is recessed.

The contents can be selected from a variety of thin shapes depending on the user's ideas, such as tickets, etc.
Possible items include small items, bookmarks, pressed flowers, and various messages.

(Effects) According to the sealed bi-fold card of the present invention, the contents A are stopped at the engagement hole 5 and do not move beyond that, so when the contents A are inserted and opened with scissors, the contents A are not cut. It has an unprecedented effect. Further, since the adhesion layer 6 is continuously formed on the outer peripheral joint surface 4 and the inner engagement hole 5, the sealing is ensured.
