본 발명은 열매 재배용 봉투에 관한 것으로, 보다 상세하게는 봉투필름의 서로 열융착된 폭방향으로의 양측 가장자리의 열융착된 부분에 힘이 그 융착면을 따라 미끌어지는 방향으로 가해지도록 열융착되어 열융착된 부분이 잘 떨어지지 않게 열융착된 열매 재배용 봉투에 관한 것이다.The present invention relates to a bag for cultivating fruit, and more particularly, heat is heat-sealed so that a force is applied to the heat-sealed portions of both edges of the envelope film in the widthwise direction of the heat-sealed width of the envelope film in a sliding direction along the fusion surface thereof. The present invention relates to a bag for cultivating fruit, which is heat-sealed so that the welded parts do not fall well.

사과나 배 등과 같은 과일의 열매나 오이, 가지, 호박 등과 같은 채소의 열매는 생장기간동안 외부에 노출된 상태에서 재배되므로 각종 병충해로부터 쉽게 손상되고 그 병충해의 방제를 위한 농약에 오염될 뿐만 아니라 각 열매마다 크기나 모양이 다르게 성장된다.Fruits such as apples and pears or fruits of vegetables such as cucumbers, eggplants and pumpkins are cultivated while exposed to the outside during the growing season, so they are easily damaged from various pests and contaminated with pesticides to control the pests. Different fruits grow in size or shape.

따라서, 최근에는 과일을 규격화시키고 병충해에 의한 피해 및 농약에 의한 오염을 줄일 수 있도록 비닐제의 봉투로 열매를 감싼 후 그 봉투의 입구를 열매가 매달린 가지에 결속끈이나 결속밴드로 묶어 밀봉시켜 재배하는 기술이 사용되고 있다.Therefore, in recent years, the fruit is wrapped in a plastic bag to standardize the fruit and reduce the damage caused by pests and pesticides, and then the inlet of the bag is tied to the branch where the fruit hangs and sealed with a tie or band. The technique to say is used.

대한민국 등록특허 제10-0494531호의 등록특허공보에는 열매 재배용 봉투가 개시되어 있으며, 도 5 및 도 6은 종래의 열매 재배용 봉투를 도시한 것이다.Korean Patent Registration No. 10-0494531 discloses an envelope for cultivating a fruit, and FIGS. 5 and 6 illustrate a conventional fruit cultivation bag.

도면을 참조하면, 열매 재배용 봉투는 대략 사각형의 봉투필름(34)를 접어 서로 대향되는 폭방향의 양측 가장자리(34a,34a)와 하부의 가장자리(32)을 열융착으로 밀봉시켜 상부에 입구(31)를 갖도록 형성된 봉투이다. 즉, 열매 재배용 봉투는 소정 폭과 길이를 갖는 수지제의 봉투필름(34)을 접어 폭방향으로의 양측 가장자리(34a,34b)가 서로 결합되어 밀봉되고, 하부에서 가장자리(32)를 따라 포개진 부분이 열융착으로 밀봉되어 봉투 형상으로 형성된다.Referring to the drawings, the fruit cultivation bag is folded in a substantially rectangular envelope film 34, the two edges (34a, 34a) and the lower edge 32 of the width direction facing each other by heat sealing to seal the inlet (31) It is an envelope formed to have). That is, the bag for fruit cultivation is folded the resin envelope film 34 having a predetermined width and length, the both edges 34a and 34b in the width direction are bonded to each other and sealed, and overlapped along the edge 32 at the bottom. The portion is sealed by heat fusion and formed into an envelope shape.

종래에는 폭방향으로의 양측 가장자리(34a,34b)의 밀봉은 봉투필름(34)의 양측 가장자리(34a,34b)를 그 내면이 서로 맞닿게 서로 포개고, 그 포개진 봉투필름(24)의 폭방향의 양측 가장자리(24a,24b)가 서로 맞닿은 면이 열융착면(36)이 되도록 열융착되어 이루어진다.Conventionally, sealing of both edges 34a and 34b in the width direction overlaps both edges 34a and 34b of the envelope film 34 so that their inner surfaces abut each other, and the width direction of the overlapped envelope film 24 is increased. The sides of the edges (24a, 24b) of the contact with each other is made of heat-sealed so that the heat-sealing surface (36).

그런데, 열매가 봉투의 크기보다 크게 성장된 경우에는 봉투에는 그 봉투를 폭방향으로 잡아당기는 방향으로 힘(F)이 가해진다. 도 6을 참조하면, 종래의 열매 재배용 봉투(3)는 폭방향으로의 양측 가장자리(34a,34b)가 그 내면이 서로 맞닿은 상태에서 서로 포개져 열융착된 구조를 갖는다. 따라서, 열매의 성장으로 봉투에 폭방향으로 가해진 힘(F)은 폭방향의 양측 가장자리(34a,34b)의 열융착면(36)에 수직인 방향으로 가해진다. 이는 열융착된 폭방향의 양측 가장자리(34a,34b) 부분(33)에 폭방향으로 가해진 힘이 상기 열융착면(36)이 서로 떨어지는 방향으로 가해지는 구조이다. 즉, 상기와 같이 폭방향의 양측 가장자리(34a,34b)의 내면이 서로 맞닿아 그 맞닿은 면이 열융착면(36)이 되는 종래의 열매재배용 봉투는 열융착면 (36)에 인장응력이 가해지는 구조를 갖기 때문에 그 열융착된 부분(33)이 잘 파열되는 단점을 갖는다.By the way, when the fruit grows larger than the size of the envelope, a force F is applied to the envelope in the direction of pulling the envelope in the width direction. Referring to FIG. 6, the conventional fruit cultivation bag 3 has a structure in which both edges 34a and 34b in the width direction overlap each other in a state in which their inner surfaces are in contact with each other and heat-sealed. Therefore, the force F applied to the bag in the width direction by the growth of the fruit is applied in the direction perpendicular to the heat-sealing surface 36 of both edges 34a and 34b in the width direction. This is a structure in which the force applied in the width direction to the edge portions 33a and 34b of the heat-sealed width direction 33 is applied in the direction in which the heat-sealed surfaces 36 are separated from each other. That is, in the conventional fruit cultivation bag in which the inner surfaces of both side edges 34a and 34b in the width direction are in contact with each other and the abutted surfaces become the heat-sealed surface 36, tensile stress is applied to the heat-sealed surface 36.

도 3 및 도 4에 도시된 제2실시예에 따른 열매 재배용 봉투는 도 1 및 도 1에 도시된 제1실시예와는 실링필름이 사용되지 않은 점을 제외하고는 대동소이하다. 즉, 제2실시예에 따른 열매재배용 봉투는 제1실시예와 마찬가지로 열융착면에 열융착면이 미끌어지는 방향으로 힘이 작용되도록 봉투필름의 폭방향으로의 양측 가장자리가 결합된 것을 특징으로 한다.The fruit cultivation bag according to the second embodiment shown in FIGS. 3 and 4 is much the same except that the sealing film is not used with the first embodiment shown in FIGS. 1 and 1. That is, the envelope for fruit cultivation according to the second embodiment is characterized in that both edges in the width direction of the envelope film are coupled to each other so that the force is applied to the heat fusion surface in the sliding direction as in the first embodiment. .

도면을 참조하면, 본 발명의 제2실시예에 따른 열매 재배용 봉투(2) 또한 소정 폭과 길이를 갖는 수지제의 봉투필름(24)을 접어 폭방향으로의 양측 가장자리(24a,24b)가 서로 결합되어 밀봉되고, 하부에서 가장자리를 따라 포개진 부분(22)이 열융착으로 밀봉되어 봉투 형상으로 형성된다. 상기 열매 재배용 봉투(2)의 상부에는 오이나, 호박 등과 같은 과일이 삽입되기 위한 입구(21)이 형성된다.Referring to the drawings, the fruit cultivation bag 2 according to the second embodiment of the present invention is also folded the resin film 24 made of a resin having a predetermined width and length, both edges 24a and 24b in the width direction of each other. Joined and sealed, the overlapping portion 22 along the edge at the bottom is sealed by heat fusion to form an envelope shape. The upper portion of the fruit cultivation bag 2 is formed with an inlet 21 for inserting fruit such as cucumber or pumpkin.

상기 제2실시예에 따른 봉투필름(24)의 폭방향으로의 양측 가장자리(24a,24b)는 일측 가장자리(24a)의 내면과 타측 가장자리(24b)의 외면이 서로 맞닿게 서로 포개어지고, 서로 포개어진 봉투필름의 양측 가장자리(24a,24b)의 맞닿은 면이 서로 열융착되어 열융착면(26)이 형성된 것을 특징으로 한다.Both side edges 24a and 24b in the width direction of the envelope film 24 according to the second embodiment are stacked so that the inner surface of one edge 24a and the outer surface of the other edge 24b abut each other and overlap each other. The abutting surfaces of both edges 24a and 24b of the jin envelope film are thermally fused to each other to form a heat fusion surface 26.

상기와 같이 열융착된 제2실시예에 따른 봉투필름(24)의 폭방향의 양측 가장자리(24a,24b)가 밀봉되게 결합된 부분(23)이 봉투필름(24)의 폭방향의 양측 가장자리(24a,24b) 중 하나의 내면과 다른 하나의 외면이 서로 맞대어진 상태에서 그 맞대어진 면이 열융착된 구조를 갖기 때문에 열융착면(26)은 봉투에 폭방향으로 잡아당겨지는 방향으로 가해진 힘(F)의 방향과 나란하다. 따라서, 상기 폭방향의 양측 가장자리(24a,24b)가 밀봉되게 결합된 부분(23)은 봉투가 확장되면서 폭방향으로 잡아당겨지는 힘(F)에 의해 열융착면(26)에는 그 융착면이 미끌어지는 방향의 힘, 즉 전단응력이 걸리기 때문에 열융착면(26)은 잘 떨어지지 않게 된다.A portion 23 in which the widthwise both edges 24a and 24b of the envelope film 24 according to the second embodiment are thermally fused as described above is hermetically coupled to both edges in the width direction of the envelope film 24. The heat-sealed surface 26 is a force exerted in a direction in which the inner face is pulled in the width direction of the bag since the butted face has a heat-sealed structure when the inner face and the outer face of the other face 24a and 24b are in contact with each other. Parallel to the direction of (F). Therefore, the portion 23 to which the two edges 24a and 24b in the width direction are sealed is sealed at the heat-sealed surface 26 by a force F that is pulled in the width direction as the envelope is expanded. Since the force in the sliding direction, that is, the shear stress is applied, the heat-sealed surface 26 does not fall well.

상기와 같은 구성에 의하여 본 발명에 따른 열매 재배용 봉투는 봉투필름의 양측 가장자리가 봉투필름이 확장되는 방향으로 가해진 힘에 의해 그 융착면이 미끌어지는 방향으로 응력이 가해지도록 열융착되어 열매의 성장으로 봉투에 폭방향으로 잡아 당겨지는 힘이 가해지더라도 열융착면이 잘 떨어지지 않는 장점을 갖는다.According to the above configuration, the fruit cultivation envelope according to the present invention is heat-sealed so that the edges of both sides of the envelope film are heat-sealed so that the stress is applied in the direction in which the fusion surface is slipped by the force applied in the direction in which the envelope film is expanded. Even if a force pulled in the width direction is applied to the envelope, the heat-sealing surface does not fall well.
