Description

종이 및 플라스틱 컨테이너의 스냅 핏 구조체Snap-fit construction of paper and plastic containers

본 특허는 패키징 기술 분야에 관한 것으로, 특히 종이 및 플라스틱 컨테이너의 스냅 핏 구조체(snap-fitting structure)에 관한 것이다.This patent relates to the field of packaging technology, in particular to snap-fitting structures of paper and plastic containers.

음료 컵은 일반적으로 폴리에스터(PET), 폴리에틸렌(PE) 또는 폴리프로필렌(PP)을 원료로 사용하며, 이는 유기 용제를 첨가한 후 고온에서 가열하고 그 다음 플라스틱 몰드에서 블로우 몰딩, 압출 또는 사출 방법으로 몰딩된다. 플라스틱은 거의 분해되지 않고 재활용률이 낮기 때문에 매우 환경 친화적이지 않다. 현재 손 주머니, 우유 주머니 등과 같이 친환경 종이 재료를 사용하기 시작한 품목이 많지만, 종이 재료를 사용하여 음료 컵을 만드는 선례는 없다. 경도와 몰딩성으로 볼 때 종이 재료는 음료 컵을 만드는 데 절대적으로 사용될 수 있다. 따라서 종이를 주원료로 하여 음료 컵을 생산하는 것은 친환경적이고 안전할 뿐만 아니라 페트병보다 더 아름다운 외관을 형성하여 더 많은 사람들에게 호평을 받을 것이다. 그러나 현재 사용되는 모든 음료 컵의 커버는 컨테이너를 직접 덮고 꽉 끼지 않기 때문에 음료 또는 부유물이 넘칠 수 있으며 커버는 외력으로 쉽게 분리된다.Beverage cups generally use polyester (PET), polyethylene (PE) or polypropylene (PP) as raw material, which is heated at high temperature after adding organic solvent, and then blow molding, extrusion or injection method in plastic mold is molded with Plastic is not very environmentally friendly because it hardly decomposes and has a low recycling rate. Currently, there are many items that have started using eco-friendly paper materials, such as hand bags and milk bags, but there is no precedent for making beverage cups using paper materials. In terms of hardness and moldability, paper materials can be absolutely used to make beverage cups. Therefore, producing beverage cups using paper as the main raw material is not only eco-friendly and safe, but also forms a more beautiful appearance than plastic bottles, and will receive favorable reviews from more people. However, since the cover of all currently used beverage cups directly covers the container and is not tight, beverages or floats can overflow, and the cover is easily detached by external force.

이를 고려하여, 본 특허는 상기 문제점을 해결하기 위해 커버 본체가 쉽게 분리되지 않는 종이 및 플라스틱 컨테이너의 새로운 스냅 핏 구조체를 제공한다.In consideration of this, the present patent provides a new snap-fit structure for paper and plastic containers in which the cover body is not easily separated to solve the above problems.

종이 및 플라스틱 컨테이너의 스냅 핏 구조체가 제공된다. 종이 및 플라스틱 컨테이너는 컨테이너 및 컨테이너를 덮는 커버 본체를 포함한다. 컨테이너는 본체 및 본체의 에지 밖으로 연장되는 클램핑 부분을 포함한다. 클램핑 부분은 본체에 연결된 연결 부분 및 상기 연결 부분 밖으로 연장되는 클램프 링을 포함한다. 본체의 중심축을 따른 단면에서, 연결 부분의 윤곽선과 본체의 중심축 사이의 끼인 각도는 예각이고 클램프 링의 윤곽선은 본체의 중심축과 평행하다. 커버 본체는 커버 바닥, 커버 바닥의 에지 밖으로 연장되는 커버 벽, 및 커버 벽의 내측벽에 배열된 플랜지를 포함한다. 클램프 링의 외경은 커버 벽의 내경과 동일하다. 플랜지와 커버 바닥은 소정 간격으로 배열되고, 클램프 링은 커버 본체가 컨테이너를 덮을 때 플랜지와 커버 바닥 사이에 클램핑된다.Snap fit structures of paper and plastic containers are provided. Paper and plastic containers include a container and a cover body covering the container. The container includes a body and a clamping portion extending out of an edge of the body. The clamping portion includes a connecting portion connected to the body and a clamp ring extending out of the connecting portion. In a cross section along the central axis of the body, the included angle between the contour of the connecting portion and the central axis of the body is an acute angle and the contour of the clamp ring is parallel to the central axis of the body. The cover body includes a cover bottom, a cover wall extending out of an edge of the cover bottom, and a flange arranged on an inner wall of the cover wall. The outer diameter of the clamp ring is equal to the inner diameter of the cover wall. The flange and the cover bottom are arranged at a predetermined interval, and a clamp ring is clamped between the flange and the cover bottom when the cover body covers the container.

또한, 플랜지와 커버 벽의 자유 단부는 소정 간격으로 배열된다.Further, the flange and the free end of the cover wall are arranged at a predetermined interval.

또한 본체의 중심축을 따른 단면에서 플랜지의 윤곽선은 원호 형상이다.In addition, the outline of the flange in a cross section along the central axis of the body is an arc shape.

또한 본체의 측벽으로부터 클램프 링까지의 거리는 플랜지의 원호 높이와 같다.Also, the distance from the side wall of the body to the clamp ring is equal to the height of the arc of the flange.

또한 본체의 중심축을 따른 방향에서 클램프 링의 높이는 플랜지로부터 커버 바닥까지의 최소 거리와 동일하다.Also, the height of the clamp ring in the direction along the central axis of the body is equal to the minimum distance from the flange to the bottom of the cover.

종래 기술과 비교하여, 본 특허가 제공하는 종이 및 플라스틱 컨테이너의 스냅 핏 구조체의 컨테이너 및 커버 본체는 각각 클램핑 부분과 플랜지를 갖는다. 커버 본체가 컨테이너를 덮을 때, 클램프 링의 외경이 커버 벽의 내경과 동일하므로 클램프 링은 플랜지의 가압 상태에서 변형된다. 클램프 링이 플랜지를 넘어가면, 클램프 링은 원래 상태로 복원되거나 여전히 변형된 상태로 커버 벽에 접하고 커버 바닥과 플랜지 사이에 클램핑되어, 컨테이너와 커버 본체가 덮는 방식으로 장착되며 외력없이는 분리되지 않는다.Compared with the prior art, the container and cover body of the snap-fit structure of the paper and plastic container provided by this patent have a clamping portion and a flange, respectively. When the cover body covers the container, the outer diameter of the clamp ring is equal to the inner diameter of the cover wall, so the clamp ring is deformed under the pressing state of the flange. When the clamp ring goes over the flange, the clamp ring is restored to its original state or still in its deformed state, abuts against the cover wall and is clamped between the cover bottom and the flange, so that the container and the cover body are mounted in a covering manner, and are not separated without external force.
