Abstract

Disclosed is a closure arrangement for a can of the type which comprises a tubular body (10) having an open upper end (13) provided with a seat (16); and a plastic lid (20) comprising a sealing portion (21) and an axially breakable seal (25) formed by a lower skirt (25a) to be seated around the upper end (13) of the tubular body (10), and an upper edge (25b) internally incorporated to the sealing portion (21) by means of breakable radial bridges (26). The upper end (13) of the tubular body (10) presents a cross section contour that is substantially smaller than the largest cross section contour of the remainder of the tubular body (10), so that the contour of the lid (20) is maintained internal to said largest cross section contour of the tubular body (10), avoiding the mutual contact of the lids (20) of two adjacent cans disposed side by side. ® KIPO & WIPO 2007

Description

캔 폐쇄구조{CLOSURE ARRANGEMENT FOR CANS}Can closure structure {CLOSURE ARRANGEMENT FOR CANS}

본 발명은 금속판제의 관형 본체를 구비하고, 이 관형 본체의 하단부에는 저벽이 부착되고, 그 상단부에는 상단부 자체를 직접 변형시키거나 환형의 상벽부를 부착시킴에 의해 압입식 플라스틱 뚜껑을 착좌 지지하기 위한 시이트가 형성된 형태의 금속판재 캔을 위한 폐쇄 구조의 개량에 관한 것이다. 더욱 상세하게는, 본 발명은 식품과 같이 점진적으로 소모하는 물품을 수용하는 전술한 형태의 캔을 위한 플라스틱 뚜껑을 구비한 폐쇄 구조에 관한 것이다.The present invention includes a tubular body made of a metal plate, and a bottom wall is attached to a lower end of the tubular body, and an upper end portion thereof supports a press-fit plastic lid by directly deforming the upper end part or by attaching an annular upper wall part. The improvement of the closed structure for the metal plate can of the form in which the sheet was formed. More particularly, the present invention relates to a closed structure with a plastic lid for a can of the type described above for receiving progressively consuming articles such as food.

식품과 같은 특정의 제품은 밀봉 용기에 보관해야 하며, 상기 밀봉 용기는 시장에 출시되었을 때 외부로부터 침범된 사실이 없음을 고객에게 보여주는 명확한 시각적 표시를 구비해야 한다. 이러한 제품들은 많은 수가 점진적 소모품이므로, 용기를 최초로 개봉한 후 수용된 제품을 점진적으로 소모해 가는 동안에 용기 내를 확실하게 기밀시켜 잔존 내용물을 보호하기 위해 용기의 뚜껑을 필요한 횟수만큼 재밀폐시킬 수 있어야 한다.Certain products, such as foods, must be stored in sealed containers, which must have clear visual indications to the customer that they are not violated from the outside when placed on the market. Since these products are a number of progressive consumables, the lid of the container must be reclosed as many times as necessary to ensure that the container is tightly sealed to protect the remaining contents during the first consumption of the container after the container is first opened. .

종래 외주링 내측, 캔 본체의 상단부의 내측, 및 기밀 이중 시임 내측에 압입시키는 압입식 뚜껑을 구비한 캔이 공지되어 있다. 상기 형식의 구조에서, 내용물의 기밀은 캔의 환형 상벽이나 캔의 원통 본체 내에 제공되는 착좌 유지 시이트 내에 뚜껑을 압입시킴으로써 보장된다.Background Art Conventionally, cans are known which have a press-fit lid which presses inside the outer circumferential ring, inside the upper end of the can body, and inside the airtight double seam. In this type of construction, the airtightness of the contents is ensured by injecting the lid into the seat retaining sheet provided in the annular top wall of the can or the cylindrical body of the can.

또, 브라질 특허출원 PI 0003727-3, PI 0203950-8 및 PI 0303138-1에는 시이트 내에 착탈 가능하게 안착 및 유지되는 시일부 및 캔의 원통 본체의 상단부의 상측 및 외주부에 배치됨과 동시에 파단이 가능한 연결체에 의해 시일부에 연결된 손으로 파단 시킬 수 있는 시일을 포함하는 플라스틱 뚜껑이 제안되어 있다.In addition, the Brazilian patent applications PI 0003727-3, PI 0203950-8, and PI 0303138-1 are disposed at the upper and outer periphery of the upper end of the cylindrical body of the seal body and the can and the seal portion detachably seated and held in the sheet, and can be broken at the same time. A plastic lid comprising a seal capable of breaking with a hand connected to the seal portion by a sieve has been proposed.

상기 본 출원인에 의한 특허출원은 점진적으로 소모하는 물품을 수용하는 캔의 뚜껑에 관련된 상기한 결점을 제거하는 한편으로 개선 가능한 결점을 가지고 있다.The patent application by the applicant has the drawbacks which can be improved while eliminating the drawbacks associated with lids of cans containing progressively consuming articles.

상기 본 출원인에 의해 제안된 종래의 기술에 있어서, 뚜껑은 캔 본체의 상단부의 상측 및 외주 측에 배치되는 시일에 의해 장착되고, 상기 상단부는 캔의 관형 본체의 횡단면의 형상과 실질적으로 동일한 형상을 가진다. 따라서, 상기 뚜껑의 시일은 그 횡단면 형상의 반경 방향 외측으로 돌출배치됨으로써 인접 배치된 다른 캔의 뚜껑의 시일부와 충돌할 가능성이 있다.In the prior art proposed by the present applicant, the lid is mounted by a seal disposed on the upper side and the outer peripheral side of the upper end of the can body, the upper end having a shape substantially the same as the shape of the cross section of the tubular body of the can. Have Thus, the seal of the lid may collide with the seal portion of the lid of another can arranged adjacently by protruding radially outward of the cross-sectional shape.

충전 및 밀폐시킨 캔의 포장 작업 및 박스 또는 하대(pallet)를 이용한 수송 작업 중에 캔은 서로 접촉된 상태를 유지하고, 캔의 뚜껑은 다른 캔의 뚜껑에 충돌하여 부분적으로나 완전히 파손되는 경우가 있다.The cans remain in contact with each other during the packaging operation of filled and sealed cans and transport operations using boxes or pallets, and the lids of the cans may collide with the lids of other cans and be partially or completely broken.

상기 시일이 부분적으로 파손된 경우에도 업자나 소비자는 모두 캔의 내용물이 손상을 받은 것으로 여긴다. 일단 캔의 내용물의 품질에 대한 신뢰가 손상을 입으면 상품화를 위해 이미 포장이 완료된 제품들을 폐기처분해야 한다.Even if the seal is partially broken, both the vendor and the consumer consider the contents of the can damaged. Once confidence in the quality of the contents of the can is compromised, products that have already been packaged must be disposed of for commercialization.

공지 기술의 다른 결점은 복수의 캔을 적층 시키면 하나의 캔의 뚜껑의 시일 의 상측에 바로 위에 적층 된 다른 캔의 관형 본체의 이중 시임 된 하단부가 수용되는 것에 의해 발생한다. 이와 같은 구조에 있어서, 적층 된 캔의 상측의 캔의 중량은 이 상측 캔의 하단부가 안착 된 하측 캔의 각각의 시일의 원주부에만 가해진다. 따라서, 적층 하중은 시일 상의 특정의 제한된 뚜껑 영역 즉 시일 상에 집중된다. 또, 상기 시일은 적층 된 캔이 연직 방향에 대해 반경 방향 외측으로 이동하는 것을 방지하기 위한 스토퍼 수단(stop means)을 형성하도록, 바람직하게는 그 외주 영역 내에서, 하나의 캔 상에 적층 된 다른 캔의 관형 본체의 하단부 형상의 외측에 유지되는 소형의 상측 원형 벽 상에 결합시켜야 한다. Another drawback of the known art arises by stacking a plurality of cans in which the double seamed lower end of the tubular body of another can is stacked just above the seal of the lid of one can. In such a structure, the weight of the can on the upper side of the stacked cans is applied only to the circumference of each seal of the lower can on which the lower end of the upper can is seated. Thus, the lamination load is concentrated on certain limited lid areas on the seal, ie the seal. In addition, the seal is formed on one can, preferably within its outer periphery, to form stop means for preventing the laminated can from moving radially outward with respect to the vertical direction. It should be joined on a small upper circular wall that is held outside of the bottom shape of the tubular body of the can.

본 발명의 포괄적인 목적은 고려되는 형식의 캔을 위한, 간단하고 저비용의 구조를 가진 개량된 폐쇄 구조를 제공하는 것이다. 상기 폐쇄 구조는 캔에 인접 배치된 동일 형식의 다른 캔의 뚜껑에 접촉하지 않도록 위치된 신뢰성이 있는 템퍼 에비던트 시일을 구비함으로써 캔의 포장, 선적 및 저장 작업 중에 뚜껑의 시일의 품질을 보증하는 플라스틱 뚜껑을 이용한다.It is a general object of the present invention to provide an improved closed structure with a simple and low cost structure for a can of the type under consideration.
