Abstract

PURPOSE: A packing with polyester nonwoven fabrics is provided to have a laminated structure and to be used in a bottle, through which fermentation gases generated in the bottle are exhausted. CONSTITUTION: The packing has a laminated structure of a sheet of polyester nonwoven fabrics(2) with a polyethylene layer(3) over one surface thereof and a foamed sheet of polyethylene(1) in which the layer of polyethylene(3) is contact with a lower side of the foamed sheet of polyethylene(1). Such a structure is formed by compressing a long fiber of polyester using a press roller at a pressure of 70 to 80 kg/cm¬2 to form a sheet of polyester nonwoven fabrics(2) having a thickness of 0.23 to 0.36 mm, coating a layer of semi-molten polyethylene(3) to a thickness of 30 micron over a surface of the sheet of polyester nonwoven fabrics(2), thermal fusing the sheet of polyester nonwoven fabrics(2) to a foamed sheet of polyethylene using a press roller in such a manner that the coated layer of polyethylene comes to contact with a lower side of the foamed sheet of polyethylene.

Description

폴리에스터 부직포를 이용한 가스배출용 패킹과 그 제조방법 {A packing for exhausting gas using a nonwoven fabric of polyester and a manufacturing method}{A packing for exhausting gas using a nonwoven fabric of polyester and a manufacturing method}

본 발명은 후도 0.21 - 0.36㎜의 폴리에스터 부직포를 폴리에칠렌 발포시트 하부면에 열융착시켜 병 내부에서 발생되는 발효가스를 밖으로 배출시킬 수 있는 폴리에스터 부직포를 이용한 가스배출용 패킹과 그 제조방법에 관한 것이다.The present invention is a gas discharge packing using a polyester nonwoven fabric capable of discharging fermentation gas generated inside the bottle by heat-sealing a polyester nonwoven fabric having a thickness of 0.21-0.36 mm to the lower surface of the polyester foam sheet and a method for manufacturing the same. It is about.

종래에는 링형의 발포패킹의 일면에 0.3미크론 기공성 필터를 부착시켜 액체는 통과하지 못하고 발효가스만 유통되어 뚜껑상판의 중앙에 천공시킨 유통공을 통해 가스가 밖으로 배출되는 방법이 있었으나 기공성 필터의 제조비가 고가이고 뚜껑상판의 중앙유통공을 통해 이물질 투입이 가능한 단점이 있었고 이를 개선한 뚜껑상판의 내면이나 또는 패킹의 일면에 중앙에서 외관으로 통과하는 가는 홈선을 형성시켜 액체는 통과하지 못하고 발효가스만 통과하도록 하는 방법도 있었으나 이렇게 세밀한 가는 홈선을 제조시 성형온도 및 압력에 따라 가는 홈선의 크기가 일정하지 않을 뿐만 아니라 이 패킹을 뚜껑의 내면에 넣고 병개구부에 나사로서 뚜껑을 체결시 가압상태에 따라 패킹의 가는 홈선의 홈크기가 각기 상이하여 홈의 크기가 클 경우에는 내부의 액체가 누출 될수 있고 너무 작은 경우에는 발효가스가 원활하게 배출되지 못하는 폐단이 있었다.Conventionally, a 0.3 micron pore filter was attached to one surface of a ring-shaped foam packing, and liquid was not passed through the fermentation gas, and gas was discharged out through a through hole drilled in the center of the lid top plate. The manufacturing cost is high and foreign materials can be introduced through the central distribution hole of the lid top plate, and the thin groove line that passes from the center to the exterior is formed on the inner surface of the lid top plate or on the packing side, so that liquid cannot pass through the fermentation gas. Although there was a method to pass only fine grooves, the size of the grooves is not constant according to the molding temperature and pressure when manufacturing these fine grooves, and the packing is placed on the inner surface of the lid and the lid is screwed into the bottle opening. Therefore, if the groove size of the thin groove of the packing is different and the groove size is large, If parts of the liquid from leaking and be too small, there were not a closed end fermentation gas is not smoothly discharged.

본 발명은 이와같은 문제점들을 개선하고져 방사되는 폴리에스터 장섬유를 70 - 80㎏f/㎝2의 압력로울러로 압축하여 후도 0.21 - 0.36㎜의 폴리에스터 부직포로 성형시키고 이 폴리에스터 부직포의 일면에는 30미크론 두께의 반용융상태 폴리에칠렌 막으로 피막층을 이루도록 코팅시켜서 폴리에틸렌 발포시트의 하부면에 폴리에칠렌 피막층이 접하도록 폴리에스터 부직포를 압력로울러로 열융착시켜서 폴리에스터 부직포를 폴리에칠렌 피막층을 이용하여 폴리에칠렌 발포시트의 하부면에 접착시킨 후 이를 뚜껑내경과 일치되게 원형판으로 절단하여 뚜껑내부에 폴리에칠렌 발포시트가 상부면으로, 폴리에스터 부직포가 하부면이 되게 삽입시키고 병의 상부 개구부에 나사부로서 체결시키면 병 내부에서 발생되는 발효가스가 폴리에스터 부직포의 내부조직을 통해 밖으로 가스가 배출되는 것으로 도면에 의거 상세히 설명하면 다음과 같다.The present invention improves these problems and compresses the spun polyester filament with a pressure roller of 70-80 kg f / cm 2 to form a polyester nonwoven fabric of 0.21-0.36 mm even afterwards, and on one side of the polyester nonwoven fabric Coated a 30-micron-thick semi-fused polystyrene film to form a coating layer and heat-sealing the polyester nonwoven fabric with a pressure roller to contact the polyester film layer on the lower surface of the polyethylene foam sheet. After adhering to the lower surface, cut it into a circular plate to match the inner diameter of the lid, and insert the polyethylene foam sheet into the upper surface and the polyester non-woven fabric into the lower surface inside, and fasten it as a screw in the upper opening of the bottle to generate the inside Fermentation gas to be made of polyester nonwoven fabric If described in detail based on the drawings as being through the tissue gas is discharged out as follows.

3 : 폴리에칠렌 막3: polyester film

방사되는 폴리에스터 장섬유를 70 - 80㎏f/㎝2의 압력로울러로 압축하여 후도 (Thickness) 0.21 - 0.36의 폴리에스터 부직포(2)로 성형시키고 이 폴리에스터 부직포의 일면에는 30미크론 두께의 반용융상태 폴리에칠렌 막(3)으로 피막층을 이루도록 코팅시킨 후 폴리에칠렌 발포시트(1)의 하부면에 폴리에칠렌 피막층(3)이 접하도록 폴리에스터 부직포를 압력로울러로 열융착시켜서 된 것으로 이렇게 일면에 폴리에칠렌 피막층을 형성시킨 폴리에스터 부직포를 폴리에칠렌 발포시트의 상,하부면에 동시에 같이 열융착 시킬수도 있는 것이다.The spun polyester filament is compressed into a pressure roller of 70-80 kg f / cm 2 and formed into a polyester nonwoven fabric (2) with a thickness of 0.21-0.36, and 30 micron thick on one side of the polyester nonwoven fabric. After coating so as to form a coating layer with a semi-melt state polystyrene film (3), and then heat-sealed the polyester nonwoven fabric with a pressure roller to contact the polyester film layer (3) to the lower surface of the polyester foam sheet (1). The polyester non-woven fabric which has been formed may be thermally fused simultaneously to the upper and lower surfaces of the polyester foam sheet.

통상 폴리에스터 수지의 용융온도가 280℃정도이고 폴리에칠렌 수지는 260℃정도이므로 폴리에스터 부직포(2)를 이질물질에 용융온도까지 상이한 폴리에칠렌 발포시트에 직접 열융착 시킬수가 없으므로 폴리에스터 부직포의 일면에 두께가 30미크론 정도의 반용융상태 폴리에칠렌 막(3)으로 코팅시키면 두께가 얇은 반용융상태의 폴리에칠렌 막이 폴리에스테 부직포의 표면조직 사이로 침투되면서 폴리에스터 부직포의 표면에 폴리에틸렌 피막층이 형성되고 이렇게 형성된 폴리에칠렌 피막층을 폴리에칠렌 발포시트 (1)와 열융착시키면 동일 재료이므로 폴리에칠렌 발포시트의 하부면에 폴리에스터 부직포가 접착이 되는 것이다.Since the polyester resin has a melting temperature of about 280 ° C. and a polyester resin of about 260 ° C., the polyester nonwoven fabric 2 cannot be directly thermally fused to a different polyester foam sheet up to the melting temperature of the heterogeneous material, so that the thickness of one side of the polyester nonwoven fabric When coated with a 30-micron semi-molten polyester film (3), a thin semi-molten polyester film penetrates between the surface texture of the polyester nonwoven fabric to form a polyethylene film layer on the surface of the polyester nonwoven fabric, thereby forming the polyethylene film layer thus formed. When heat-sealed with the polyethylene foam sheet 1, the polyester nonwoven fabric is attached to the lower surface of the polyethylene foam sheet because it is the same material.

이렇게 70 - 80㎏f/㎝2의 압력로울러로 성형된 후도 0.21 - 0.36㎜의 폴리에스터 부직포를 폴리에칠렌 피막층을 이용하여 폴리에칠렌 발포시트의 하부면에 접착시킨 후 이를 뚜껑내경과 일치되게 원형판으로 절단하여 뚜껑내부에 폴리에칠렌 발포시트가 상부면으로, 폴리에스터 부직포가 하부면이 되게 삽입시키고 병의 상부 개구부에 나사부로서 체결시키면 병 내부에서 발생되는 발효가스가 폴리에스터 부직포의 내부조직을 통해 밖으로 가스가 배출되는 것으로 이때 폴리에스터 부직포의 후도가 0.21㎜ 이하가 되면 부직포의 두께가 얇아 가스배출이 잘 되지 않고 0.36㎜ 이상이 되면 두께가 두꺼운 부직포의 내부 조직 사이로 액체까지 유통이 되어 내부의 액체가 뚜껑밖으로 누출될 수가 있는 것이다.Even after molding into a pressure roller of 70-80 kg f / cm 2 , a 0.21-0.36 mm polyester nonwoven fabric was bonded to the lower surface of the polyethylene foam sheet by using a polyethylene coating layer and then cut into a circular plate to match the inner diameter of the lid. When the polyethylene foam sheet is inserted into the upper surface of the lid, the polyester nonwoven fabric becomes the lower surface, and is fastened as a screw part to the upper opening of the bottle, the fermentation gas generated inside the bottle flows out through the internal tissue of the polyester nonwoven fabric. At this time, if the thickness of polyester nonwoven fabric is 0.21mm or less, the thickness of the nonwoven fabric is thin and gas discharge is not good.If the thickness is more than 0.36mm, the liquid is distributed between the internal tissues of the thick nonwoven fabric and the liquid inside the lid It can leak out.

그리고 일면에 폴리에칠렌 피막층을 형성시킨 폴리에스터 부직포를 폴리에칠렌 발포시트의 상,하부면에 동시에 같이 열융착시키면 뚜껑내부에 패킹을 삽입할 때 상,하부면을 구별할 필요가 없으므로 뚜껑과 패킹의 조립공정이 신속하여 지는 것이다.And if the polyester non-woven fabric with a polyester film layer formed on one side is heat-sealed at the same time on the upper and lower surfaces of the polyethylene foam sheet, there is no need to distinguish the upper and lower surfaces when inserting the packing inside the lid, so the process of assembling the lid and packing This is losing quickly.
