본 발명은 내부가 구획된 봉지에 관한 것으로서, 보다 상세하게는 내용물을 종류별로 분리하여 담을 수 있으며, 제조도 용이한 새로운 구조의 내부가 구획된 봉지 및 그 제조방법에 관한 것이다. The present invention relates to an enclosed bag, and more particularly, to an enclosed bag and a method of manufacturing the same, which can contain contents separately by type and are easily manufactured.

흔히, 마트 등에서 물품을 구입하면, 비닐봉지에 담아 운반한다. 그런데 구입한 물품들을 종류별로 여러 장의 비닐봉지에 나눠 담지 않고 하나의 비닐봉지에 담기 때문에 비닐봉지에 담아진 물품들이 서로 섞이게 되며, 이에 따라 계란이나, 두부, 빵이나 딸기 등과 같이 깨지거나 뭉그러지기 쉬운 식품들이 다른 물품에 눌려 손상되기도 한다. Often, when goods are purchased at a mart, they are transported in plastic bags. However, because the purchased items are stored in one plastic bag instead of being divided into several plastic bags for each type, the items contained in the plastic bag are mixed with each other. As a result, eggs, tofu, bread, and strawberries are easily broken or crushed. Foods can also be damaged by being pressed by other items.

한편, 이러한 문제점을 해결하기 위해 종래에는 도 1에 도시된 바와 같이, 비닐봉지(1)의 중앙부가 길이방향으로 융착되어 봉지의 내부가 구획된 비닐봉지가 제안되기도 하였다. 그러나 이와 같이 비닐봉지의 중앙부가 융착됨에 따라 공간이 구획된 비닐봉지는 도 2에 도시된 바와 같이, 내부 공간(2,3)이 대략 ∞형상을 취하므로 비닐공지의 내부가 구획되기 전의 내부에 비해 상대적으로 좁아져서 물품을 많이 담을 수 없는 단점이 있다. 또한 융착부위가 상대적으로 취약하여 쉽게 찢어지기도 한다. 따라서 이러한 이유로 종래 내부가 구획된 비닐봉지는 상용화되지 못하였다. On the other hand, in order to solve such a problem, as shown in FIG. 1, a plastic bag in which the center portion of the plastic bag 1 is fused in the longitudinal direction and the inside of the bag is partitioned has been proposed. However, as the center of the plastic bag is fused in this way, the plastic bag divided into spaces, as shown in FIG. There is a disadvantage that can not contain a lot of goods because it is relatively narrow. Also, the welded areas are relatively fragile and easily torn. Therefore, for this reason, conventionally divided plastic bags have not been commercialized.

본 발명은 상기의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 봉지내부가 격벽에 의해 구획되어 물품을 종류별로 나눠 담을 수 있으며, 또한, 격벽에 의해 내구 공간이 구획되므로 봉지의 중앙부를 부착시켜 봉지가 구획된 경우에 비해 봉지의 구획된 공간이 넓게 확보되므로 상대적으로 많은 물품을 담을 수 있고, 하나의 필름을 절첩시켜 제조되므로 제조도 용이한 새로운 구조의 내부가 구획된 봉지 및 그 제조방법을 제공하는 것이다.The present invention is to solve the above problems, an object of the present invention is to enclose the inside of the bag is partitioned by the partition to store the goods by type, and also because the durable space is partitioned by the partition wall to attach the central portion of the bag Compared to the case where the bag is partitioned, the partitioned space of the bag is secured wider, so it can contain a relatively large number of items, and is manufactured by folding a single film. To provide.

본 발명에 따르면, 내용물을 담도록 된 봉지에 있어서, 상기 봉지(10)의 내부에는 격벽(16)이 형성되어, 봉지(10)의 내부공간이 상기 격벽(26)에 의해 구획된 것을 특징으로 하는 내부가 구획된 봉지가 제공된다. According to the present invention, in the bag containing the contents, the partition wall 16 is formed inside the bag 10, the inner space of the bag 10 is characterized in that partitioned by the partition wall 26 An enclosed bag is provided.

이하, 본 발명을 바람직한 실시예를 통해 구체적으로 설명하면 다음과 같다. Hereinafter, described in detail through the preferred embodiment of the present invention.

도 3은 본 발명의 일 실시예를 보인 사시도이고, 도 4는 그 제조과정을 보인 도면이다. 본 발명은 도시된 바와 같이, 내부공간의 좌우폭이 전후폭보다 넓게 형성된 비닐봉지로서, 그 내부에는 봉지내부를 좌우로 구획하는 격벽(26)이 형성된다. 이러한 본 발명의 제조공정을 살펴보면 다음과 같다. 3 is a perspective view showing an embodiment of the present invention, Figure 4 is a view showing the manufacturing process. As shown in the present invention, the left and right width of the inner space is a plastic bag formed wider than the front and rear width, the partition 26 is formed in the inside partitioning the inside of the bag from side to side. Looking at the manufacturing process of the present invention as follows.

먼저, 연속적으로 공급되는 합성수지필름을 적당한 간격으로 절단하여 좌우로 긴 직사각형상의 단위 필름(20)을 만든다. 이 직사각형상 필름(20)의 좌우 단부 중 일단부(21)를 필름의 중앙부분에 근접되도록 필름(20) 전면으로 접는다. 그리고 접혀진 일단부(21)를 필름에 융착시킨다. 이와 같이 하면 제1공간(12)이 형성된다. First, the synthetic resin film that is continuously supplied is cut at appropriate intervals to form a unit film 20 that is long left and right. One end 21 of the left and right ends of the rectangular film 20 is folded toward the entire surface of the film 20 so as to be close to the center of the film. Then, the folded end portion 21 is fused to the film. In this way, the first space 12 is formed.

이어서 필름의 타단부(22)를 필름(20)의 배면에 겹쳐지게 접는다. 이때 배면으로 접혀지는 타단부(22)가 필름의 전면으로 접혀진 일단부(21)와 소정량 겹쳐지도록 한다. 그리고 배면으로 접혀진 타단부(22)를 필름에 융착시킨다. 이와 같이 하면 상기 제1공간(12)과 나란하게 제2공간(14)이 형성되는데, 각각 전후로 접혀진 단부(21,22) 사이에 위치되는 필름의 중앙부분이 제1, 2공간(12,14)을 구획하는 격벽(26)이 된다. Subsequently, the other end 22 of the film is folded to overlap the back surface of the film 20. At this time, the other end portion 22 which is folded to the rear surface is overlapped with a predetermined amount by the one end portion 21 which is folded to the front of the film. And the other end 22 folded to the back is fused to a film. In this case, a second space 14 is formed in parallel with the first space 12. The central portions of the film positioned between the ends 21 and 22 folded back and forth are respectively the first and second spaces 12 and 14. It becomes the partition 26 which partitions ().

이어서 상기 격벽(26)을 전후로 겹쳐지도록 길이방향을 따라 반으로 접고, 필름의 하단부를 융착시킨다. 이와 같이 하면 상기 제1, 2공간(12,14)의 하단부가 봉해지며, 상단이 개구된 봉지(10)가 형성된다. 그리고 필요에 따라 후공정으로 봉지의 상단 중앙부를 절취하고 좌우 단부에 슬릿을 형성하여 봉지(10)의 상단 좌우측에 손잡이(18)를 형성시킨다. Next, the partition wall 26 is folded in half along the longitudinal direction so as to overlap the front and rear, and the lower end of the film is fused. In this way, lower ends of the first and second spaces 12 and 14 are sealed, and an encapsulation 10 having an upper end is formed. Then, if necessary, the upper center portion of the bag is cut in a later process, and slits are formed at left and right ends to form handles 18 at the upper left and right sides of the bag 10.

이와 같이 제조되는 본 발명에 의한 봉지는 격벽(26)에 의해 내부공간이 좌우로 배치되는 제1, 2공간(12,14)으로 구획된다. 따라서 사용자는 구입한 물품을 종류별로 제1, 2공간(12,14)에 나눠 담는다. 예를 들면 상대적으로 파손되기 쉬운 물품은 제1공간(12)에, 상대적으로 파손될 우려가 적은 물품은 제2공간(14)에 담아, 파손되지 쉬운 물품이 다른 물품에 눌리거나 부딪혀서 손상되는 것이 방지되도록 한다. The encapsulation according to the present invention manufactured as described above is partitioned into first and second spaces 12 and 14 in which internal spaces are arranged left and right by the partition wall 26. Therefore, the user divides the purchased goods into first and second spaces 12 and 14 by type. For example, a relatively fragile article is stored in the first space 12 and a relatively fragile article is stored in the second space 14 to prevent the fragile article from being damaged by being pressed or hit by another article. Be sure to

특히, 본 발명은 종래 중앙부가 부착되어 공간이 구획 형성된 봉지와 달리 내부에 격벽(26)이 형성되어 있으므로, 이 격벽(26)에 의에 구획된 제1, 2공간(12,14)이 넓게 확보되어 상대적으로 많은 물품을 담을 수 있는 장점이 있다. 특히, 격벽(26)이 전후로 접혀진 상태에서 봉지(10)의 하단이 융착되므로 봉지(10)를 펼치면 상기 격벽(26)이 펴지면서 상대적으로 제1, 2공간(12,14)이 더 넓게 확보된다. Particularly, in the present invention, since a partition 26 is formed inside, unlike a bag in which a center is attached and a space is partitioned, the first and second spaces 12 and 14 partitioned by the partition 26 are wide. There is an advantage that can be secured to hold a relatively large number of items. In particular, since the lower end of the bag 10 is fused in the state in which the partition 26 is folded back and forth, when the bag 10 is unfolded, the partition 26 is opened and the first and second spaces 12 and 14 are relatively secured. do.

경우에 따라서는 필름(20)의 좌우 양단부(21,22)를 모두 전면이나 배변으로 접어서 봉지(10)를 제조할 수도 있다. 이 경우에는 필름의 좌우 단부 중 일단부(21)를 배면으로 접고 부착하여 제1공간(12)을 형성한 다음, 필름(20)의 타단부(22)도 필름(22)의 배면으로 접는데, 이때에도 역시 제1공간(12)을 형성한 일단부(21)와 일정량 중첩되도록 필름(20)의 타단부(22)를 접고, 타단부(22)를 필름(20)에 부착시켜 제2공간(14)을 형성한다. 이와 같이 하면 먼저 접혀져서 타단부(22) 내측으로 위치되는 필름(20)의 일단부(21)가 제1, 2공간(12,14)의 격벽(26)이 된다. 이와 같이 한 후, 전술한 바와 같은 동일한 방법으로 나머지 공정을 행한다. In some cases, the bag 10 may be manufactured by folding both the left and right ends 21 and 22 of the film 20 to the front side or the bowel movement. In this case, one end 21 of the left and right ends of the film is folded and attached to form a first space 12, and then the other end 22 of the film 20 is also folded to the back of the film 22. Also, at this time, the other end 22 of the film 20 is folded so as to overlap a predetermined amount with the one end 21 which forms the first space 12, and the other end 22 is attached to the film 20 to form a second. The space 14 is formed. In this case, one end portion 21 of the film 20 that is folded first and positioned inside the other end portion 22 becomes the partition wall 26 of the first and second spaces 12 and 14. After doing so, the remaining steps are performed in the same manner as described above.

이와 같이 하면, 도 5에 도시된 바와 같이, 필름(20)의 일단부(21)가 봉지(10) 내부로 위치되므로 필름의 양단부(21,22)가 각각 전면과 배면으로 절첩된 경우와 달리 봉지(10)의 전, 후면 중 일면에만 필름의 단부가 노출되어 보인다. 필름의 단부가 노출된 봉지의 표면은 필름의 단부에 의해 요철이 형성되어 광고나 회사로그 등을 인쇄하기 다소 곤란하나, 필름의 단부가 노출되지 않은 봉지의 표면은 표면이 매끈하므로 광고나 회사로그 등을 용이하게 인쇄할 수 있다. In this case, as shown in FIG. 5, since one end 21 of the film 20 is positioned inside the bag 10, unlike the case where both ends 21 and 22 of the film are folded to the front and the rear, respectively. The ends of the film are exposed to only one surface of the front and rear surfaces of the bag 10. The surface of the bag where the end of the film is exposed is somewhat difficult to print an advertisement or company log due to irregularities formed by the end of the film. However, the surface of the bag without the end of the film is smooth, so the surface of the bag is smooth. Etc. can be easily printed.

또한, 본 발명이 과자 포장봉지에 적용될 수도 있는데, 이 경우에는 도 6에 도시된 바와 같이, 전술한 방법으로 하부가 개구된 봉지를 만들고, 제1공간(12)과 제2공간(14)에 내용물을 담은 다음, 봉지(10)의 상단부를 융착시킨다(H). 이와 같이 하면 내부가 밀봉된 포장봉지가 제조된다. In addition, the present invention can also be applied to a confectionery bag, in this case, as shown in Figure 6, by making the bag opening the lower portion by the above-described method, in the first space 12 and the second space 14 After containing the contents, the upper end of the bag 10 is fused (H). In this way, a sealed packaging bag is manufactured.

이상에서는 봉지가 합성수지필름으로 제조되는 것으로 설명하였으나, 본 발명은 종이제로도 제조가 가능하다. 또한, 봉지의 제조과정에서 단부를 부착시키는 수단으로 접착제나 접착필름이 사용될 수도 있다. In the above described as the bag is made of a synthetic resin film, the present invention can also be made of paper. In addition, an adhesive or an adhesive film may be used as a means for attaching the end portion in the manufacturing process of the bag.

이상에서와 같이 본 발명에 의하면, 봉지내부가 격벽(26)에 의해 구획되어 물품을 종류별로 나눠 담을 수 있으며, 또한, 격벽(26)에 의해 내구 공간이 제1, 2공간(12,14)으로 구획되므로 봉지의 중앙부를 부착하여 봉지가 구획된 경우에 비해 봉지의 구획된 공간이 넓게 확보되므로 상대적으로 많은 물품을 담을 수 있는 봉지가 제공된다. 특히, 격벽(26)이 전후로 겹쳐지도록 길이방향으로 접혀진 상태에서 하단부가 부착되므로 봉지의 내부를 펼치면 접혀진 격벽(26)이 펼쳐지면서 상대적으로 제1, 2공간(12,14)이 더 넓게 확보된다. As described above, according to the present invention, the inner part of the bag is partitioned by the partition wall 26 so as to divide the articles into different types, and the partition 26 has a durable space in the first and second spaces 12 and 14. Since the compartment is attached to the center portion of the bag, the compartment space of the bag is secured wider than the case where the bag is partitioned, thereby providing a bag that can hold a relatively large number of articles. In particular, since the bottom portion is attached in the longitudinally folded state so that the partition wall 26 overlaps back and forth, when the inside of the bag is unfolded, the folded partition 26 is expanded to secure the first and second spaces 12 and 14 more widely. .

또한, 본 발명은 하나의 필름을 절첩하여 제조되므로 다수 장의 필름을 부착시켜 제조하는 경우에 비해 제조가 용이한 장점이 있다. In addition, the present invention is manufactured by folding one film, there is an advantage that is easy to manufacture compared to the case of manufacturing by attaching a plurality of films.
