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, Kafe, Webinar 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.

초록
▼

A device for dispensing a dental material comprises first compartment and the second compartment formed between interconnected sheet-like layers. The compartments encapsulate a first flowable component and a second flowable component of the dental material. The device has a first seal and a second seal for sealing the first compartment and the second compartment in the device. Each seal is adapted to automatically open in consequence of forcing a component of the dental material toward the seal. The capacity of the first compartment and the second compartment relative to each other is dimensioned such that squeezing out the first component from the first compartment by compressing the first compartment causes the first seal and the second seal to open. The device preferably allows easy and quick activation for use of the stored components.

1. A device for dispensing a dental material, comprising: a first and a second compartment formed between interconnected sheet-like layers, the first compartment at an inactivated stage encapsulating a first flowable component of the dental material;the second compartment at an inactivated stage encapsulating a second flowable component of the dental material, wherein the first compartment and the second compartment are substantially air free at an inactivated stage;a reservoir for jointly holding at least parts of the first component and the second component at an activated stage;a first seal openably sealing the first compartment and the second compartment at the inactivated stage from each other;a second seal openably sealing the second compartment and the reservoir at the inactivated stage from each other;each of the first seal and the second seal being formed by the layers in a non-permanent sealing area in which the layers are interconnected such that they are disconnectable in consequence of forcing a component of the dental material between the layers;wherein the capacity of the first compartment and the second compartment relative to each other is dimensioned such that squeezing out the first component from the first compartment by compressing the first compartment causes the first seal and the second seal to open; andwherein, when the device is in the activated stage, the dental material has a predetermined desired mixing ratio of the first component and the second component, and, when the device is in the inactivated stage, the device contains a first amount of the first component in the first compartment and a second amount of the second component in the second compartment at a ratio of the amounts which is different from the desired mixing ratio;wherein the desired mixing ratio is defined by a quantity n of the first component relative to a quantity m of the second component, and wherein the first amount of the first component present in the first compartment corresponds to a quantity of about n+m and the second amount of the second component present in the second compartment corresponds to a quantity of about m. 2. The device of claim 1, wherein at least one of the layers has a bulge for providing the first compartment with a predetermined capacity, and a further bulge for providing the second compartment with a further predetermined capacity. 3. The device of claim 1, wherein the first compartment has a first capacity for the first component which is greater than a second capacity for the second compartment. 4. The device of claim 3, wherein the first capacity is greater than twice of the second capacity. 5. The device of claim 4, wherein the first capacity and the second capacity form a ratio of one of 3:1, 4:1, 5:1, 10:1 or 11:1. 6. The device of claim 1, wherein the first compartment and the second compartment are arranged within an area in a plane of the layers that matches within a circle of about 20 mm. 7. The device of claim 6, wherein the first compartment in a plane of the layers has an elliptical shape with a longer axis and a shorter axis, and wherein the second compartment is arranged in a dimension along the shorter axis of the ellipse. 8. The device of claim 7, wherein the second compartment in a plane of the layers has an elliptical shape with a longer axis and a shorter axis, with the longer axis of the ellipse of the second compartment being oriented generally in line with the shorter axis of the ellipse of the first compartment. 9. The device of claim 1, wherein the outlet is formed by an elongated channel which is formed by the layers, and wherein the channel is adapted to receive an applicator for the dental material. 10. The device of claim 1, comprising an encoding formed by a shape formed in at least one of the layers. 11. The device of claim 1, wherein, when the device is in the activated stage, the device has a dispensed amount of dental material substantially equal to the amount of the first component in the first compartment when the device is in the inactivated stage. 12. The device of claim 1, wherein, when the device is in the activated stage, a predetermined portion of the first component is present in the second compartment. 13. A method of dispensing a dental material comprising the steps of: providing a device as claimed in claim 1;compressing the first compartment and essentially not compressing the second compartment such that essentially all of the first component is displaced from the first compartment and at least part of the second component is displaced by the first component from the second compartment; andmixing at least portions of the first component and the second component in the reservoir. 14. The method of claim 13, further comprising the step of compressing the first compartment on a generally flat surface by use of a thumb or finger, and the step of rolling the thumb or finger towards the second compartment to compress the second compartment. 15. A device for dispensing a dental material, comprising: a first and a second compartment formed between interconnected sheet-like layers, the first compartment at an inactivated stage encapsulating a first flowable component of the dental material;the second compartment at an inactivated stage encapsulating a second flowable component of the dental material, wherein the first compartment and the second compartment are substantially air free at an inactivated stage;a reservoir for jointly holding at least parts of the first component and the second component at an activated stage;a first seal openably sealing the first compartment and the second compartment at the inactivated stage from each other;a second seal openably sealing the second compartment and the reservoir at the inactivated stage from each other;each of the first seal and the second seal being formed by the layers in a non-permanent sealing area in which the layers are interconnected such that they are disconnectable in consequence of forcing a component of the dental material between the layers;wherein the capacity of the first compartment and the second compartment relative to each other is dimensioned such that squeezing out the first component from the first compartment by compressing the first compartment causes the first seal and the second seal to open; andwherein, when the device is in the inactivated stage, the device contains a first amount of the first component in the first compartment and a second amount of the second component in the second compartment at a first ratio, and when the device is in the activated stage, the dental material has an activated mixing ratio of the first component and the second component that is different from the first ratio;wherein the activated mixing ratio is defined by a quantity n of the first component relative to a quantity m of the second component, and wherein the first amount of the first component present in the first compartment corresponds to a quantity of about n+m and the second amount of the second component present in the second compartment corresponds to a quantity of about m.
