Abstract
Description
본 발명은 공기배출통로가 형성되어 있으며 열봉합가능한 노즐이 설치된 진공포장지와 상기 진공포장지에 사용되는 노즐에 관한 것으로, 특히 상기 노즐은 진공포장지가 진공된 후에 진공포장지의 개봉부와 함께 열봉합되는 진공포장지에 관한 것이다.The present invention relates to a vacuum packaging paper in which an air discharge passage is formed and a heat sealable nozzle is installed, and a nozzle used in the vacuum packaging paper. In particular, the nozzle is a vacuum that is heat sealed together with an opening of the vacuum packaging paper after the vacuum packaging paper is vacuumed It is about a wrapping paper.
일반적으로 진공포장지는 내부에 음식물 등이 수납된 후 진공포장기를 사용하여 진공포장지의 내부가 진공상태로 형성되어, 음식물 등이 진공 보관하는데 사용되는 것이다.In general, the vacuum packaging paper is used to store food and the like in a vacuum state by using a vacuum packaging machine after the food or the like is stored in the vacuum packaging, the vacuum packaging paper is formed.
종래의 진공포장지에는 특허공개번호제92-0700998호이고 발명의 명칭이 "플라스틱 백을 진공봉합하는 장치"에 기재된 엠보싱이 형성된 진공포장지가 있으며, 도1에 도시되어 있다. 상기 진공포장지(21)는 내부표면에 엠보싱(25)이 형성되어, 진공포장시에 엠보싱(25)에 의하여 공기배출통로가 형성되었고, 도2에 도시된 진공포장기(20)에 의하여 진공되고 열봉합되었다.Conventional vacuum packaging papers include a vacuum packaging paper having embossing described in Patent Publication No. 92-0700998 and entitled " Apparatus for vacuum sealing a plastic bag ", which is shown in FIG. The vacuum packaging paper 21 is embossed 25 is formed on the inner surface, the air discharge passage was formed by the embossing 25 at the time of vacuum packaging, vacuum and heat by the vacuum packaging machine 20 shown in FIG. Sutured.
구체적으로, 종래의 진공포장기(20)는 베이스(32), 후드(33), 이들 사이에형성된 진공챔버(34), 상기 진공챔버(34)를 진공시키는 진공펌프(도시 안됨) 및 진공포장지(21)의 개봉부를 열봉합하는 열봉합수단(50)으로 이루어진다.Specifically, the conventional vacuum packaging machine 20 has a base 32, a hood 33, a vacuum chamber 34 formed therebetween, a vacuum pump (not shown) and a vacuum packaging paper for vacuuming the vacuum chamber 34 ( It consists of a heat sealing means 50 for heat-sealing the opening of the 21.
이러한 종래의 챔버식 진공포장기에 의하여 진공포장지(21)가 진공포장되는 경우에는, 식료품 등의 피포장물이 진공포장지(21) 내부인 수납공간에 수납되고, 상기 진공포장지(21)의 개봉부가 진공챔버(34)의 내부에 위치된 후에 상기 후드(33)가 베이스(32) 위로 하강되어, 진공포장지와 진공챔버는 밀폐된다. 그런 후에 소정의 스위치가 작동되면 진공펌프가 동작하게 되고, 상기 진공펌프의 동작에 따라 진공챔버(34)가 진공되고, 이에 따라, 진공포장지(21)의 내부도 진공이 되고, 열봉합수단(50)에 의하여 진공포장지(21)의 개봉부가 열봉합되었다. 이때 진공포장지(21)의 내부 일측면에 도1에 도시되듯이 엠보싱(25)이 형성되어 있기 때문에 상기 엠보싱(25)에 의해 진공포장지(21) 내부의 공기가 흡입되는 것이다.When the vacuum packaging paper 21 is vacuum-packed by the conventional chamber type vacuum packaging machine, a packaged object such as foodstuff is stored in a storage space inside the vacuum packaging paper 21, and the opening portion of the vacuum packaging paper 21 is vacuumed. After being placed inside the chamber 34, the hood 33 is lowered above the base 32 so that the vacuum wrapping paper and the vacuum chamber are sealed. Thereafter, when a predetermined switch is operated, the vacuum pump is operated, and the vacuum chamber 34 is vacuumed according to the operation of the vacuum pump, whereby the inside of the vacuum packaging paper 21 is also vacuumed, and the heat sealing means ( 50, the opening part of the vacuum packaging paper 21 was heat-sealed. At this time, since the embossing 25 is formed on one inner surface of the vacuum wrapping paper 21 as shown in FIG. 1, the air inside the vacuum wrapping paper 21 is sucked by the embossing 25.
그러나, 종래의 챔버식 진공포장기에 의한 진공포장에는 고가의 엠보싱이 형성된 진공포장지가 소요되는 문제점이 있었다. 또한, 종래의 진공포장지는 제조공정에서 가열된 한쌍의 롤러에 의해 엠보싱이 파열되어 불량품이 발생되기 쉬운 문제점이 있었다.However, there has been a problem in that a vacuum packaging paper with expensive embossing is required for vacuum packaging by a conventional chamber vacuum packaging machine. In addition, the conventional vacuum packaging paper has a problem that the embossing is ruptured by a pair of rollers heated in the manufacturing process, a defective product is likely to occur.
한편, 종래의 진공포장지에는 엠보싱이 형성되지 않은 진공포장지도 있었다. 이러한 진공포장지는 대개 노즐식 진공포장기에 의해 진공되고 열봉합되었다. 그러나, 종래의 노즐식 진공포장기는 진공시에 노즐이 진공포장지의 내부에 삽입되고, 진공후 열봉합시에 노즐이 진공포장지에서 분리되어야 하여, 이러한 진공과 열봉합시 노즐의 위치를 제어하기 위해 복잡한 장치가 소요되는 문제점이 있었다.그리고, 다른 형태의 노즐식 진공포장기는 노즐이 진공포장기에 삽입된 위치에서 노즐의 앞부분에 위치되는 진공포장지의 부분이 열봉합되기도 하였으나, 이 경우에는 노즐이 진공포장지의 개봉부에 위치하여 에어트랩이 발생되어 진공포장이 어렵고, 노즐의 삽입 깊이에 해당하는 만큼 진공포장지가 낭비되는 문제점이 있었다.On the other hand, the conventional vacuum packaging paper also had a vacuum packaging in which embossing was not formed. These vacuum wrappers were usually vacuumed and heat sealed by a nozzle type vacuum wrapper. However, in the conventional nozzle type vacuum packaging machine, in order to control the position of the nozzle during the vacuum and heat sealing, the nozzle is inserted into the inside of the vacuum packing paper during the vacuum and the nozzle must be separated from the vacuum packing paper during the heat sealing after the vacuum. In another type of nozzle type vacuum packaging machine, a part of the vacuum packaging paper positioned at the front of the nozzle is heat-sealed at the position where the nozzle is inserted into the vacuum packaging machine. Located in the opening of the wrapping paper is an air trap is difficult to vacuum packaging, there was a problem that the vacuum wrapping paper is wasted as much as the insertion depth of the nozzle.
상기한 종래의 문제점 등을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 진공포장지에 별도로 엠보싱이 형성될 필요가 없으며 저렴하며 효과적으로 진공되는 진공포장지를 제공하는 것이다.The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vacuum packaging paper which is inexpensive and effectively vacuumed without the need for embossing to be formed separately on the vacuum packaging paper.
또한, 본 발명의 다른 목적은 진공포장지가 진공된 후에 진공포장지의 개봉부와 함께 열봉합되는 노즐이 설치된 진공포장지를 제공하는 것이다.In addition, another object of the present invention is to provide a vacuum packaging paper provided with a nozzle that is heat-sealed together with the opening of the vacuum packaging paper after the vacuum packaging paper is vacuumed.
또한, 본 발명의 다른 목적은 국부적인 에어트랩이 발생되지 않으며 신속히 진공되는 진공포장지를 제공하는 것이다.In addition, another object of the present invention is to provide a vacuum packaging paper which does not generate a local air trap and is rapidly vacuumed.
