Description

밀폐용기용 뚜껑 조립체{A COVER ASSEMBLY FOR AIRTIGHT CONTAINER}Lid Assembly for Airtight Containers {A COVER ASSEMBLY FOR AIRTIGHT CONTAINER}

본 발명은 밀폐용기용 뚜껑 조립체에 관한 것으로; 더욱 상세하게는 냄새나 수분의 유출됨이 없이 음식물을 안전하게 담아 보관할 수 있도록 잠금기능을 적용할 수 있는『밀폐용기용 뚜껑 조립체』에 관한 것이다.The present invention relates to a lid assembly for a sealed container; More specifically, the present invention relates to a "sealing container lid assembly" to which a locking function can be applied so that food can be safely stored and stored without leakage of smell or moisture.

일반적으로 음식물을 냉장고 등에 보관하는 경우 자체의 독특한 냄새 및 수분이 유출됨으로써, 이를 방지하기 위해 밀폐용기에 음식물을 담아 보관한다. 이러한 종래 밀폐용기는 상부가 개방된 용기본체와, 이 용기본체를 개폐할 수 있도록 잠금날개가 마련된 뚜껑을 갖추고 있다. 용기본체는 합성수지를 원료로 사각 또는 원 통 형태로 사출 성형되며, 내부에 저장공간이 형성된다. 또한, 용기본체 측벽의 개방 단부는 잠금날개를 걸기 위한 걸림돌기가 돌출되게 마련된다. 그리고 잠금날개는 뚜껑의 가장자리를 따라 바깥측으로 선회 가능하게 일체로 이루어지며, 각각에는 걸림돌기에 걸릴 수 있도록 걸림턱이 마련된다. 따라서 용기본체의 상부에 뚜껑을 덮은 후 여기에 잠금날개들을 각각 아래측으로 내리누르면, 걸림턱이 용기본체의 걸림돌기에 탄성 결합되어 뚜껑이 견실하게 잠긴다. 그리고 잠금날개를 상측으로 들어올리면, 걸림턱 구속이 해제되어 뚜껑을 열 수 있다.In general, when food is stored in a refrigerator or the like, its own unique smell and moisture is leaked out, so that food is stored in an airtight container to prevent it. Such a conventional airtight container is provided with a container body with an open top and a lid provided with a lock wing to open and close the container body. The container body is injection molded in a square or cylindrical shape using synthetic resin as a raw material, and a storage space is formed therein. In addition, the open end of the side wall of the container body is provided to protrude a locking projection for engaging the locking wing. And the locking wing is made integrally rotatable outward along the edge of the lid, each is provided with a locking jaw to be caught by the engaging projection. Therefore, after covering the lid on the upper portion of the container body and pressing down the locking wings to each side, the locking jaw is elastically coupled to the locking projection of the container body to lock the lid securely. When the locking wing is lifted upward, the locking jaw restraint is released to open the lid.

그러나 종래 밀폐용기에서는 보관되는 내용물에 의해 합성수지(PP:)로 제작된 용기본체가 쉽게 변색되는 단점이 있으며, 최근에는 합성수지 특유의 환경호르몬에 대한 부정적인 이미지로 인해 제품 구매력이 떨어지고 있다. 특히, 용기본체와 뚜껑 재료는 프로필렌을 중합하여 얻는 열가소성 수지인 폴리프로필렌(polypropylene; 일명, PP라 칭함) 인데, 이것은 연성이 우수한 반면 투명도가 좋지 않다.However, in the conventional hermetically sealed container has a disadvantage that the container body made of synthetic resin (PP :) easily discolored by the contents stored, and in recent years the purchasing power of the product is falling due to the negative image of the environmental hormone unique to the synthetic resin. In particular, the container body and the lid material is a polypropylene (polypropylene; also referred to as PP) which is a thermoplastic resin obtained by polymerizing propylene, which is excellent in ductility but poor in transparency.

또한, 최근에는 환경호르몬을 유발시키지 않으면서 투명도가 우수한 트라이탄 수지를 사용하기도 한다. 이 트라이탄 수지는 미국의 세계적인 기업 이스트만 케미컬이라는 회사에서 새롭게 개발한 친환경 신소재로 환경호르몬 의심물질인 비스페놀-A(BPA)를 비롯하여 인체에 유해한 가소제를 첨가하지 않은 순수한 폴리에서트 원료를 말하는 것으로, 플라스틱과 유리의 장점(투명도)을 모두 갖추고 있어서 밀폐용기 제품에 사용되고 있다. 그러나 트라이탄 수지는 투명도는 우수한 반면 연성은 없어서 잠금날개를 갖는 뚜껑 제품에는 적용하지 못하고 있다. 즉, 반복적으로 접히면서 사용하는 "잠금날개가 일체로 마련된 뚜껑 제품"을 트라이탄 수지로 성형하는 경우 잠금날개의 스냅힌지(snap-hinge) 부분이 쉽게 파손된다.In recent years, tritan resins having excellent transparency without causing environmental hormones are also used. This tritan resin is a new eco-friendly material newly developed by the US company Eastman Chemical. It is a pure poly raw material that does not contain any harmful plasticizers, including bisphenol-A (BPA), an environmental hormone suspected substance. It has all the advantages (transparency) of plastic and glass, so it is used in airtight container products. Tritan resins, however, do not apply to lid products with locking wings due to their excellent transparency and lack of ductility. That is, when the "lid product with a lock wing is integrally formed" repeatedly used to be molded with a tritan resin, the snap-hinge portion of the lock wing is easily broken.

이로 인해, 최근에는 용기본체는 트라이탄 수지를 원료로 제작하고, 잠금날개를 갖는 뚜껑은 폴리프로필렌(PP) 수지를 원료로 제작한 제품이 출시되고 있지만; 소비자들로부터는 폴리프로필렌 수지를 재료로 만들어진 용기 뚜껑으로 인해 전체적인 제품 구매력을 잃고 있다. For this reason, in recent years, a container main body is made of a tritan resin as a raw material, and a lid having a locking wing is made of a product made of polypropylene (PP) resin as a raw material; Consumers are losing overall product purchasing power due to container lids made of polypropylene resin.

본 발명은 이러한 문제점을 해결하기 위한 것으로; 본 발명의 목적은 뚜껑 본체와 잠금날개 부위를 이종의 재료로 성형하여 일체화할 수 있도록 뚜껑 조립체의 구조를 개선하여, 제품을 다양하게 연출할 수 있으며 투명도가 우수하고 친환경 소재인 트라이탄 수지를 효과적으로 적용할 수 있는 『밀폐용기용 뚜껑 조립체』를 제공하는 것이다.The present invention is to solve this problem; An object of the present invention is to improve the structure of the lid assembly to be integrated by molding the lid body and the lock wing parts of different materials, can produce a variety of products and excellent application of tritan resin which is excellent in transparency and eco-friendly material It is to provide a "sealing container lid assembly" that can be.

또한, 본 발명의 다른 목적은 플라스틱과 유리의 장점을 모두 갖고 있는 트라이탄 신소재를 밀폐용기 뚜껑에 적용할 수 있으면서 연성이 요구되는 잠금날개를 일체화하여 잠금기능 역시 구현할 수 있는 『밀폐용기용 뚜껑 조립체』를 제공하는 것이다.In addition, another object of the present invention can be applied to a new tritan material having both the advantages of plastic and glass to the sealed container lid while integrating the lock wing that requires ductility, the "capsule assembly for sealed containers can also be implemented. It is to offer.
