일반적으로, 택배를 통해 물품을 배송할 때는, 물품을 택배박스에 담아 배송하거나, 합성수지재질의 봉투에 담아 배송하고 있다.Generally, when delivering goods through courier, the goods are delivered in a delivery box or in an envelope made of synthetic resin.

이중에서, 봉투는 두께가 얇은 물품을 담는데 주로 사용된다.Among these, bags are mainly used to contain thin items.

그런데, 이러한 봉투는 얇은 시트를 재단하여 접은 후, 접착하여 제조됨으로, 내부에 담겨진 물품을 효과적으로 보호하기 어려운 문제점이 있었다.However, since these bags are manufactured by cutting, folding, and gluing thin sheets, there is a problem in that it is difficult to effectively protect the items contained inside.

이러한 문제점을 해결하기 위하여, 봉투의 외측면에 통상 뽁뽁이라 불리는 에어캡을 부착하여 완충성능을 향상시킨 봉투가 개발되어 사용되고 있으나, 이러한 제품의 경우, 외관이 수려하지 못하고, 외부면에 주소 등을 기재하는 것이 불편한 문제점이 있었다.In order to solve this problem, bags with improved buffering performance have been developed and used by attaching air caps, commonly called bubble wrap, to the outer surface of the bag. However, these products do not have a nice appearance and have addresses, etc. on the outer surface. There was a problem that was inconvenient to write down.

따라서, 이러한 문제점을 해결할 수 있는 새로운 방법이 필요하게 되었다.Therefore, a new method to solve these problems has become necessary.

(10), an inner bag (20) with an inlet (21) formed on the upper side and inserted into the outer bag (10), and a cushioning member (30) attached to the outer surface of the inner bag (20). It is composed.

이를 자세히 설명하면, 상기 외부봉투(10)는 양측 둘레부와 하측둘레부가 상호 연결된 전면판(13)과 후면판(14)이 구비되며, 상기 막음편(12)은 후면판(14)의 상단에 상측으로 연장되도록 구비된다.To explain this in detail, the outer envelope 10 is provided with a front plate 13 and a back plate 14 where both side circumferences and lower circumferences are connected to each other, and the closing piece 12 is located at the top of the back plate 14. It is provided to extend upward.

상기 내부봉투(20)는 양측 둘레부와 하측둘레부가 상호 연결된 전면판(22)과 후면판(23)이 구비된 것으로, 사이즈가 상기 외부봉투(10)에 비해 작게 구성되어, 내부봉투(20)를 외부봉투(10)의 내부에 완전히 삽입할 수 있도록 구성된다.The inner envelope 20 is provided with a front plate 22 and a back plate 23 connected to each other on both sides and a lower perimeter, and is smaller in size than the outer envelope 10, so that the inner envelope 20 ) is configured to be completely inserted into the interior of the outer envelope (10).

상기 완충부재(30)는 적절한 두께와 폭을 갖는 종이재질로 구성되고 중간부가 절곡되어, 상기 내부봉투(20)의 하측 둘레부를 덮는 절곡부(31)와, 상기 절곡부(31)에서 상측으로 연장되며 상기 내부봉투(20)의 전후면에 접착고정되는 전후방 연장부(32,33)를 갖도록 구성된다.The cushioning member 30 is made of paper material with an appropriate thickness and width and is bent in the middle, forming a bent portion 31 covering the lower circumference of the inner envelope 20 and extending upward from the bent portion 31. It is configured to have front and rear extension parts (32, 33) that extend and are adhesively fixed to the front and rear surfaces of the inner envelope (20).
