연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An expandable and collapsible cooler includes: a base defining a bottom portion of the cooler; an upper rim defining an upper portion of the cooler; and a collapsible cooler wall extending between and attached to the base and the upper rim and surrounding an interior storage space of the cooler. The cooler wall includes a flexible elastomeric membrane that includes a plurality of hinge lines at which the membrane is configured to bend such that the membrane is transitional between a collapsed configuration and an expanded configuration. The cooler is transitional between an expanded configuration and a collapsed configuration by bending of the membrane along the hinge lines. Each configuration is a stable configuration of the cooler. The collapsible cooler wall includes peripheral portions thereof that nest within each other when the collapsible cooler wall is fully collapsed. The collapsible cooler wall tapers in extending from the upper rim.

The cooler of claim 1, wherein (i) each membrane includes inner and outer surfaces, each surface including upper and lower hinge faces, and(ii) each hinge line has a complementary hinge line, such that when its membrane is folded at a first hinge line associated with upper and lower hinge faces of one of the inner and outer surfaces, its membrane is also folded at a second, complementary hinge line associated with upper and lower hinge faces of the other of the inner and outer surfaces. 3. An expandable and collapsible cooler, comprising: (a) a base defining a bottom portion of the cooler;(b) an upper rim defining an upper portion of the cooler; and(c) a collapsible and expandable cooler wall extending between and attached to the base and the upper rim and surrounding an interior storage space of the cooler, the cooler wall comprising inner and outer collapsible and expandable walls that are tapered and self-supporting, each of the inner and outer walls comprising a flexible elastomeric membrane that includes a plurality of hinge lines at which the membrane is configured to bend such that the membrane is transitional between a collapsed configuration and an expanded configuration, the inner and outer collapsible and expandable walls not requiring an intermediate space to be filled with pressurized air for support;(d) wherein the cooler is transitionable between an expanded configuration for use of the cooler, and a collapsed configuration during nonuse of the cooler, by bending of each membrane of the cooler wall along the hinge lines, each of the configurations being a stable configuration of the cooler;(e) wherein the collapsible cooler wall comprises perimeter portions thereof that nest within each other when the collapsible cooler wall is fully collapsed;(f) wherein the collapsible cooler wall tapers in extending from the upper rim;(g) wherein each hinge line has upper and lower hinge faces associated therewith; and(h) wherein upper and lower hinge faces associated with a particular hinge line are configured to generally abut one another when the membrane it is defined in is folded about the particular hinge line. 4. The cooler of claim 3, wherein the collapsible cooler wall tapers inwardly in extending from the upper rim to the base, and wherein the periphery of the cooler wall proximate the upper rim is greater than the periphery of the cooler wall proximate the base. 5. The cooler of claim 3, wherein the cooler wall comprises a common bottom wall to which the collapsible inner and outer walls are joined and from which the collapsible inner and outer walls extend. 6. The cooler of claim 3, wherein the cooler wall comprises an inner collapsible wall that extends from and is attached to the upper rim, and that includes an integral bottom wall; and wherein the cooler wall comprises an outer collapsible wall that extends between and is attached to the base and the upper rim. 7. The cooler of claim 6, wherein the outer collapsible wall includes an integral bottom wall, and wherein the intermediate space defined between the outer collapsible wall and the inner collapsible wall includes the space between the bottom wall of the inner collapsible wall and the bottom wall of the outer collapsible wall. 8. The cooler of claim 3, wherein each membrane is formed of silicone rubber. 9. The cooler of claim 3, wherein each membrane includes a stiffening portion. 10.
