Abstract

The present invention relates to a plastic bag with an aluminum binding band, wherein a roll bag having a welding band added to the vicinity of a cutting groove to cut the cutting groove so that the cutting groove can be an inlet and enabling the welding band to be formed on the opposite side of the inlet. The roll bag enables a binding aluminum foil to be attached to an outer wall of the inlet of the cutting groove. Moreover, the aluminum foil can be maintained in a state in which the aluminum foil is folded as an accordion is expanded or compressed by using strength of the aluminum foil, and can release the inlet when being unfolded so that the inlet does not need to bound additionally.

Description

알루미늄 묶음띠를 가지는 비닐봉지{Vinyl envilope with aluminium thinfilm band}Plastic bag with aluminum bundle {Vinyl envilope with aluminum thinfilm band}

본 발명은 알루미늄 묶음띠를 가지는 비닐봉지에 관한 것이다.The present invention relates to a plastic bag having an aluminum bundle.

묶음끈을 가지는 봉지는 국내실용신안등록 제20-0210377호, 국내공개특허 10-2010-0039515호와 같이 비닐봉지 입구에 끈을 삽압하여 노출된 양단을 묶어 봉지를 개페하는 과일보호용 봉투 형태로 알려졌으나, 끈을 사용하여 묶었다가 풀어야 하므로 , 묶고 푸는 과정이 필요하다.Bags with a bundle of strings are known in the form of fruit protection bags that open the bags by tying the exposed ends by inserting a string at the entrance of a plastic bag, such as Korean Utility Model Registration No. 20-0210377 and Korean Patent Publication No. 10-2010-0039515. However, it must be tied and loosened using a string, so it is necessary to tie and loosen it.

알루미뉴박을 사용하는 외장재 기술은 국내공개특허 10-2014-0141429호와 같이 알루미늄박을 외장재로 사용하는 전지용 외장재로 이는 내열성 확보 및 강도 보강용의 다층시트 형태로 한정한 기술로 비닐봉지에는 적용된 바 없다.The exterior material technology using aluminum foil is a battery exterior material that uses aluminum foil as an exterior material, as in Korea Patent Publication No. 10-2014-0141429, which is limited to the form of a multilayer sheet for securing heat resistance and reinforcing strength. none.

또한 일정 길이마다 절단한 비닐봉지를 원하는 매수로 적재한 다음 별도의 끈으로 매달아 유통하거나, 일정 길이마다 절단한 봉지를 접은 다음 종이 티슈 꺼내듯이 일매씩 케이스에 수용한 다음 입구에서 일매씩 꺼내 사용하는 방식도 알려져 있다.In addition, the plastic bags cut at a certain length may be loaded in the desired number of sheets, and then hung and distributed with separate strings, or the bags cut at certain lengths may be folded and stored in a case like a paper tissue, and then taken out one by one from the entrance. The method is also known.

롤백(Roll-bag)은 관체형 원단을 연신하여 일정 폭의 누름 타원체를 감은 원단을 풀면서 일정 길이마다 융착띠와 절단홈을 동시에 형성한 다음, 다시 일정 길이를 보빈에 감은 제품이다. 사용시에는 사용자가 일매의 롤백을 절단홈에서 분리시키면 분리된 절단홈은 입구가 되고 입구가 아닌 반대편 융착띠는 봉지 기능을 하는 막힘 기능을 한다. 이 상태에서 사용자가 분리한 비닐봉지의 입구를 벌려 원하는 내용물을 채운 다음에는 내용물의 이탈을 막기 위하여 비닐봉지 입구 양단을 서로 묶어야 한다. 때문에 내용물을 다시 꺼낼 때에는 묶음부를 다시 풀어야하는 불편함이 있다.Roll-bag is a product that stretches tubular fabric, unwinds the fabric of a pressed ellipsoid of a certain width, simultaneously forms a fusion band and a cutting groove for each predetermined length, and then winds the predetermined length to the bobbin again. In use, if the user removes a roll of rollback from the cutting groove, the separated cutting groove becomes an inlet and the opposite fusion band, not the inlet, functions as a sealing function. In this state, after opening the plastic bag separated by the user to fill the desired contents, the ends of the plastic bag openings should be tied together to prevent the contents from being separated. Because of the inconvenience to untie the bundle again when taking out the contents.

본 발명은 이를 해결하고자 하는 것으로, 본 발명의 목적은 롤백의 절단 입구에 알루미늄박을 띠상으로 부착시켜 알루미늄박의 강도를 이용하여 입구가 쉽게 닫히거나 열릴 수 있도록 하여, 별도로 묶음이 필요없는 롤백을 제공하려는 것이다.The present invention is to solve this, an object of the present invention is to attach the aluminum foil to the cutting inlet of the roll back in the form of a band so that the inlet can be easily closed or opened by using the strength of the aluminum foil, rolls do not need to bundle separately Is to provide.

이를 위한 본원발명은 절단홈 부근의 입구 인접 부위에 융착띠를 나란히 폭방향으로 부가하여 절단홈을 분리하면 절단홈 부위가 봉지의 입구가 되고, 입구 반대편은 융착띠로 막힌 비닐봉지에서,The present invention for this purpose is to add a fusion band side by side in the width direction adjacent to the cutting groove in the width direction to separate the cutting groove is the opening of the cutting groove, the opposite side of the inlet in a plastic bag clogged with fusion band,

절단홈이 분리되면 입구가 되는 입구 외측벽에 입구와 함께 접히면 묶음 기능을 하는 알루미늄박을 띠상으로 부착한 묶음이 용이한 비닐봉지를 제공한다.When the cutting groove is separated from the inlet to the entrance to the outer wall is folded to provide an easy-to-bundle plastic bag attached to the aluminum foil serving as a band in the form of a band.

본 발명은 롤백의 절단 입구에 알루미늄박을 띠상으로 부착시켜 알루미늄박의 강도를 이용하여 입구가 쉽게 닫히거나 열릴 수 있도록 하여, 별도로 묶음이 필요없는 롤백을 제공하려는 것이다.The present invention is to provide a roll-back without the need to bundle separately by attaching the aluminum foil to the cutting inlet of the roll back in a band shape so that the inlet can be easily closed or opened by using the strength of the aluminum foil.

본 발명은 알루미늄박을 비닐봉지 입구 외측벽에 부착하는 핫멜트를 사인파나 삼각파 형태로 이어지게 융착하며 접힘이 용이하고 풀림도 용이하도록 작용하여 사용성을 좋게한다.The present invention fuses the hot melt for attaching the aluminum foil to the outer wall of the plastic bag inlet in the form of a sine wave or a triangular wave, and facilitates folding and easy unwinding, thereby improving usability.

이하 본원발명의 실시예를 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

본원 발명은 절단홈(1)부근의 입구 인접 부위에 융착띠(2)를 나란히 폭방향으로 부가하여 절단홈(1)을 분리하면 절단홈(1) 부위가 봉지의 입구(3)가 되고, 입구(3) 반대편은 융착띠(2)로 막힌 비닐봉지(4)에서,According to the present invention, when the fusion band 2 is added to the inlet adjacent portion near the cutting groove 1 in the width direction to separate the cutting groove 1, the cutting groove 1 portion becomes the inlet 3 of the bag. Opposite the inlet (3) is a plastic bag (4) clogged with a fusion band (2),

절단홈(1)이 분리되면 입구가 되는 입구(3) 외측벽에 입구와 함께 접히면 묶음 기능을 하는 알루미늄박(10)을 띠상으로 부착한다.When the cutting groove 1 is separated, the aluminum foil 10 serving as a bundle is attached to the outer wall of the inlet 3, which becomes an inlet, in a band form.

본 발명에서 알루미늄박을 띠상으로 부착하는 것은 접거나 펼칠때 그 상태르르 유지하는 지탱력을 확보하기 위함이다. 사용시 단지 접기만 하면 접은 상태를 유지하도록 기능하려는 것이다.In the present invention, the aluminum foil is attached in the form of a band in order to secure the holding force of the aluminum foil when it is folded or unfolded. When you use it, you just want to fold to keep it folded.

상기, 알루미늄박(10)과 비닐봉지(4)의 입구(3) 외측면에는 핫멜트층(20)으로 융착된다. 이는 핫멜트층이 인체에 무해하고, 얇게 융착이 가능하고, 비닐봉지의 융착온도보다 용융온도가 낮아서 융착이 용이하게 때문이다. 바람직하기는 알루미늄박(10)의 이면에 용융된 핫멜트를 바른 다음 비닐봉지(4) 입구 외측벽에 눌러 붙이면 되고, 수동으로도 가능하고, 로딩 언로딩 수단과 핫멜트건 수단을 결합하면 자동화도 가능하다.The outer surface of the inlet 3 of the aluminum foil 10 and the plastic bag 4 is fused with a hot melt layer 20. This is because the hot melt layer is harmless to the human body, can be thinly fused, and is easily fused because the melting temperature is lower than that of the plastic bag. Preferably, the molten hot melt is applied to the rear surface of the aluminum foil 10, and then pressed onto the outer wall of the inlet of the plastic bag 4, which can be done manually or by combining the loading unloading means and the hot melt gun means. .

상기, 핫멜트층(20)은 접힘이 용이한 사인파나 삼각파 형으로 융착된 것이 좋다. 이는 핫멜트(20)가 폭방향으로 일정하게 융착되는 것이 아닌 지그 재그로 융착되도록 하여 넓은 면적을 융착하되 핫멜트의 양은 줄이면서, 동시에 도 3 과 같이 사인파나 삼각파형 형태로 하면 접힘이 보다 용이하고 일정한 지탱력을 제공하여 접힘과 풀림에 좋도록 기능한다.The hot melt layer 20 may be fused in a sinusoidal or triangular wave form that is easily folded. This allows the hot melt 20 to be fused with a jig zag instead of being uniformly fused in the width direction, but fusion of a large area, while reducing the amount of hot melt, while simultaneously forming a sinusoidal or triangular waveform as shown in FIG. Provides support and functions for folding and unwinding.

아울러 비닐봉지(4) 입구(3)의 일측 외면이나(도 4), 양측 외면(도 5)에 알루미늄박(10)을 핫멜트로 융착할 수 있는바, 이는 알루미늄박(10)의 두께와 폭 및 용도에 따라 선택하여 제조가능하다. 도 5 와 같이 입구(3) 양측 외면에 알루미늄박(10)을 부착하는 경우는 접힘 강도가 강한 용도로, 도 4 와 같이 일측 외면에 알루미늄박(10)을 부착하는 경우는 접힘 강도가 약한 용도로 사용하면 좋다.In addition, the aluminum foil 10 may be hot melted on the outer surface of one side of the plastic bag 4, the inlet 3 (FIG. 4), or on both sides of the outer surface (FIG. 5), which is the thickness and width of the aluminum foil 10. And selectable according to the use. When the aluminum foil 10 is attached to both outer surfaces of the inlet 3 as shown in FIG. 5, the folding strength is strong, and when the aluminum foil 10 is attached to one outer surface as shown in FIG. 4, the folding strength is weak. Good to use.
