Description

The present invention relates to an envelope that is excellent in design, easy to put an inclusion, and easy to take out.

Conventionally, envelopes are usually rectangular and plain. However, attempts have been made to appeal to the recipient of the envelope visually by decorating the envelope cover with letters or illustrations. For example, it is effective to decorate the envelope cover with letters or illustrations to make it easier for recipients of close relationships or to increase the advertising effectiveness of recipients such as direct mail. .

In addition to the illustration on the cover, an envelope for a new year's gift bag having a peripheral edge that is not a postal envelope is proposed as an envelope with a visual impact decorated by other methods (Patent Document 1). The idea is to form a pattern-shaped front plate with a rim as a material using a sheet of paper or the like, and a back plate of the same shape made of the same material as the front plate. The front plate flat part and the entire back plate flat part are bonded via an adhesive layer to form a storage chamber in the center, and an opening cutting strip is provided on the back plate in an arc shape above the storage chamber. The upper opening and the both ends of the opening cutting strip formed in an arc shape form U-shaped upper cutting strips, and the entire surface of the front and back plates positioned above the opening cutting strip is an adhesive layer. To form a whole-surface adhesive plate surface, and further, a pressure-sensitive envelope piece is adhered to the back plate via a release paper.

However, the envelope is devised substantially assuming a New Year's gift bag. In addition, according to the present invention, “if the both ends of the front plate and the back plate are slightly gripped, the entire adhesive plate and the back plate portion located below the opening cut line of the back plate are curved in opposite directions to each other. It is said that the opening of the upper opening can be performed smoothly, but in fact, if the both ends of the front and back plates are gripped slightly, the front and back plates will stick together in the same direction. It is difficult to bend and open smoothly. In addition, the space between the front and back plates forming the storage room is extremely narrow toward the sides of the storage room, that is, the bonding position between the front and back panels. When taking in and out, there is a problem that it becomes difficult to put in and out because the stationery etc. are caught in a narrow place. Moreover, since the area | region which adhere | attaches a front board and a back board becomes only the peripheral part vicinity of a front board and a back board except a storage chamber, there exists a problem that the intensity | strength as an envelope main body becomes insufficient. If the outer peripheral portion is enlarged for the purpose of ensuring the strength, there is a problem that it becomes difficult to lightly grip both side edges of the envelope and curve the front and back plates of the opening in opposite directions.

About.

The envelopes according to claims 1 to 4 are substantially parallel so that two elongated bent bodies having a substantially V-shaped cross section face each other along the left end and the right end of the storage portion, and the substantially V-shaped inner corners face each other. In particular, the folded body has sufficient elasticity that the front sheet and the back sheet are not in close contact with each other at the left and right intermediate portions, so that the front sheet and the back sheet are at the left and right intermediate portions. Separated without close contact. Therefore, it is easy to expand the opening when the enclosure is sealed and taken out.
The folded body has enough elasticity that the front sheet and the back sheet are not closely spaced apart from each other at the left and right middle parts, and a force acts in the direction of opening the substantially V-shaped inner corner, so both sides of the envelope If the edge is lightly gripped, the front sheet and the back sheet of the opening can be easily bent in opposite directions, that is, the opening can be expanded.
In addition, the elongated bent body having a substantially V-shaped cross section also serves as a guide when the inclusion is taken in and out. Therefore, it is easy to put and remove the inclusion.
Further, since the elongated bent body having a substantially V-shaped cross section is inserted along the left end and the right end of the storage portion, the distance between the front sheet and the back sheet forming the envelope body is set on both sides of the envelope body, that is, It does not become extremely narrow toward the bonding position between the front sheet and the back sheet, and does not get caught when an inclusion such as a stationery is taken in or out.
In addition, since the outer surface of the elongated bent body with a substantially V-shaped cross section is bonded to the front sheet and the back sheet, the strength can be secured without increasing the bonding area between the front sheet and the back sheet, and design freedom is achieved. The degree increases. In addition, strength can be secured without increasing the adhesion area between the front sheet and the back sheet, and the outer peripheral part does not need to be enlarged. Easy to bend in the opposite direction easily.
In addition, the elongated bent body having a substantially V-shaped cross section has a force acting in the direction in which the substantially V-shaped inner corner opens, so that the entire envelope becomes somewhat three-dimensional and excellent in design.

In the envelopes according to claims 3 and 4, the bellows body is connected to the ends of the two bent bodies on the opening side, so that the opening is easily opened. The bellows body also serves as a guide for loading and unloading the enclosed material in the vicinity of the opening of the envelope. Therefore, it is easy to put and remove the inclusion.

In the envelopes according to claims 5 and 6, a rectangular sheet having a substantially V-shaped cross section and having folded portions along the left and right ends facing the inner corners is inserted along the left and right ends of the storage portion. Therefore, in particular, the rectangular sheet has sufficient elasticity so that the front sheet and the back sheet are not in close contact with each other at the left and right intermediate portions, so that the front sheet and the back sheet are not in close contact with each other at the left and right intermediate portions. ing. Therefore, it is easy to expand the opening when the enclosure is sealed and taken out.

By gently grasping both side edges, it is possible to easily curve the front and back sheets of the opening in opposite directions, that is, to widen the opening.
In addition, the folded portion where the cross-section is substantially V-shaped and the inner corners face each other also serves as a guide for taking in and out the enclosure, so that the enclosure can be easily put in and taken out.
In addition, since a rectangular sheet having a substantially V-shaped cross section and a folded portion with the inner corners facing each other is inserted along the left end and the right end of the storage portion, the front sheet and the back sheet forming the envelope body Is not extremely narrowed toward both sides of the envelope body, that is, the bonding position between the front sheet and the back sheet, and is not caught when an infill such as a stationery is taken in and out.
In addition, since the outer surface of the rectangular sheet having a substantially V-shaped cross section and having folded portions along the right and left ends facing the inner corners is bonded to the front sheet and the back sheet, the front sheet and the back sheet The strength can be secured without increasing the outer peripheral portion of the envelope body, which is the bonding area, and the degree of freedom in design is increased. Strength can be ensured without increasing the bonding area between the front and back sheets, and the outer periphery does not need to be enlarged, making it easier to grip both sides of the envelope lightly and easily opening and closing the front and back sheets Easy to curve in the opposite direction.
In addition, since the cross-section is substantially V-shaped and the force acts in the direction in which the folded portion where the inner corners face each other is opened, the entire envelope is somewhat three-dimensional and excellent in design.

In the envelopes according to claims 7 to 8, the substantially rhomboid or substantially oval cylindrical body having a flat cross section is inserted along both ends of the storage portion. Since the back sheet has sufficient elasticity to be spaced apart from each other at the left and right intermediate portions, the front sheet and the back sheet are spaced apart from each other at the left and right intermediate portions. Therefore, it is easy to expand the opening when the enclosure is sealed and taken out.
The tubular body has sufficient elasticity that the front sheet and the back sheet are not in close contact with each other at the left and right intermediate portions, and a force acts in the opening direction of the tubular body. If grasped lightly, the front sheet and the back sheet of the opening can be easily bent in opposite directions, that is, the opening can be expanded.
In addition, the substantially rhombic or substantially elliptical cylindrical body having a flat cross section also serves as a guide for taking in and out the enclosure, so that the enclosure can be easily put in and taken out.
In addition, since a substantially rhombic or substantially elliptical cylindrical body having a flat cross section is inserted, the space between the front sheet and the back sheet forming the envelope body is on both sides of the envelope body, that is, the front sheet and the back sheet. It does not become extremely narrow toward the bonding position with the sheet, and does not get caught when taking in and out the inclusion such as a stationery.
Moreover, since the outer surface of the substantially rhombic or substantially elliptical cylindrical body having a flat cross section is bonded to the front sheet and the back sheet, the outer peripheral portion of the envelope body, which is an adhesion region between the front sheet and the back sheet, is The strength can be secured without increasing the size, and the degree of freedom in design increases. Strength can be ensured without increasing the bonding area between the front and back sheets, and the outer periphery does not need to be enlarged, making it easier to grip both sides of the envelope lightly and easily opening and closing the front and back sheets Easy to curve in the opposite direction.
In addition, since the force is applied in the opening direction of the substantially rhomboid or substantially oval cylindrical body having a flat cross section, the entire envelope becomes somewhat three-dimensional and excellent in design.
