Title: Contact lens package with insertion feature
Inventor: BAUMAN ROBERT C
IPC: A45C11/00
Filed: 1997-10-03
Abstract: PURPOSE: Provided is a contact lens storage container, more particularly, a storage container for contact lenses which make it easy to insert the lens into the eye. CONSTITUTION: Provided is a contact lens container comprising an integrally molded one-piece synthetic resin receptacle providing a well having a peripheral wall with a bottom portion, and a flange extending about the periphery of the upper end of well. The bottom portion has a generally concave inner surface for seating a contact lens thereon and is being relatively rigid. The peripheral wall of the well has an annular, resiliently deflectable inversion portion above the bottom portion, and it is invertible to position the bottom portion of the well above the plane of the flange. Pressing upwardly against the bottom portion of the well inverts the inversion portion of the well and dispose the bottom portion with the lens thereon above the plane of the flange. The receptacle is moved against the eye of the user to place the lens against the cornea and thereby cause the lens to seat thereon.

Abstract: 본 발명은 하천이나 저수지의 여수로(余水路) 또는 관계용수로에 설치하여 저수측(貯水側)의 수위를 항상 일정 범위 내로 유지하기 위한 자동수문에 관한 것으로서, 수위감지센서의 수위감지에 따라 압력발생장치가 가동되면서 발생된 압력이 실린더를 수축 또는 팽창시킴과 동시에 실린더로드가 수축 또는 팽창되면서 팽창된 힘에 의해 자동으로 개폐작동이 이루어지면서도 개방시 저수측의 하부에 저장된 물의 배수가 원활하게 이루어지고, 또 수문본체와 근접한 저수측 바닥에 토사나 자갈이 쌓이더라도 개폐작동이 원활하게 이루어지며, 배수를 신속하게 할 수 있음과 함께 특히 홍수시에 돌이나 나무 등이 수문본체에 충돌하여 수문본체가 파손되는 현상을 방지할 수 있는 자동수문을 제공하는 것을 과제로 한다. 
     본 발명의 자동수문은, 수로의 폭방향 양측에 소정의 간격을 두고 축조된 벽체(1)와, 각 벽체(1)의 중앙부에 직립되게 고정된 지지대(77)와, 양 지지대(77)에 중공의 사각 판 형상으로 되어 있음과 함께 수문의 본체 상단부에는 회동축(55)이 구비되며 회동축(55)의 양쪽 끝단부에는 수문을 개폐시키기 위한 유동축 장설용 연결대(88)가 구성된다. 
     연결대(88)에 구성되는 유동축(66)과 함께 지지대(77)에 장설되는 회동축(22)의 사이를 실린더(44)과 결합되는 실린더로드(33)를 장설하여 회동이 가능하도록 연결 구성되며 수문의 본체는 수로바닥과 경사상태를 이루도록 상기 벽체(1) 사이에 배치됨과 함께 수문의 본체에 구성되는 상기 회동축(55)과 수문의본체사이에는 용수의 침투 또는 이물질의 침투를 방지하여주는 회동 가능한 구조의 밀폐판(99)으로 회동 가능하게 결합되어 있는 수문본체(11)와, 수문본체(11)를 회동축(55)과 연결되어 구성된 연결결대을 중심으로 ½.⅓.⅔.¼.정도의 하단부 위치에 승강 조작하기 위하여 대각선방향으로 실린더로드(33)와 결합되는 실린더(44)가 유동축(22.66)에 의해 지지대(77)와 연결대(88)사이에 회동 가능하게 결합되고, 저수측의 수위를 감지하기 위한 수위감지센서(6)그리고 수위감지 센서와 연결되는 압력발생장치가 배관으로 실린더(44)와 연결된 구조로서, 수위감지센서의 수위 감지에 따라 실린더의 로드(33)가 신장 또는 축소되는 것에 의해 수문본체가 회동축(55)을 중심으로 회동하여 자동 개폐되는 구조이며 수문의 본체내부에는 수문이 차지하고 있는 비중을 낮추어 주기위하여 수소와 같은 비중이 가벼운 물체를 충진함에 있어서 수문에 가해지는 대기온도가 높게 올라가게 되면 수문의 내부가 팽창할 수가 있는데 이러한 문제점을 해결하기 위하여 팽창조절 자동밸브(21)를 수문의 본체 내에 구성시킨도록 된 것을 특징으로 한다. 
     본 발명의 자동수문은 수위감지센서의 수위감지에 의해 전달되는 압력발생장치의 압력에 의해 수문의 개폐작동이 자동으로 이루어지는 것임은 물론, 개방상태일 때 수문본체의 저수측 면과 수로 바닥 사이에 형성되는 배수공간을 통하여 저수측 하부의 물이 원활하게 배수되는 것이므로 자연적 정화 기능에 의하여 발생되는 퇴적물들이 하층부에 도달하는 순간 배출되게 되는 구조적 특성에 의하여 적조현상 및 녹조현상을 방지할 수 있다. 또 개방 작동시 수문본체의 하부가 배수측의 상부로 회동하는 것이므로 수문본체와 근접한 저수측 수로의 바닥에 토사나 자갈이 쌓여 있는 상태라 하더라도 개방 작동이 원활하게 이루어 진다. 또한 실린더로드와 실린더가 수로와 맞닷아 있지 않음으로 인하여 제품의 수명을 연장시킬수가 있음은 물론 수문본체의 하부로 유입되는 또는 배출하고자 하는 양 만큼 배수가 이루어지는 것이므로 배수 단면적을 극대화하여 신속한 배수를 도모할 수 있고 특히 배수시 수문본체에 돌이나 나무 등이 충돌하여 수문본체가 파손될 우려가 없는 것이다.
