Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
77 words
In a package of the type having a container for housing an article including at least one dry component, the container being adapted to maintain a specialized internal environment until opened, the improvement comprising an inner receptacle housed within the container for receiving and holding the dry component, and normally closed inlet means communicating with the inner receptacle for introducing a quantity of hydrating fluid thereto to hydrate the dry component without compromising the container internal environment.
Claim 2
Dependent Claim
77 words
In a package of the type having a container for housing an article including at least one dry component, the container being adapted to maintain a specialized internal environment until opened, the improvement comprising an inner receptacle housed within the container for receiving and holding the dry component, and normally closed inlet means communicating with the inner receptacle for introducing a quantity of hydrating fluid thereto to hydrate the dry component without compromising the container internal environment.
Claim 3
Dependent Claim
27 words
The package of claim 1 wherein the inlet means comprises septum means penetrable by a syringe needle and being self-sealing following penetration and withdrawal of such needle.
Claim 4
Dependent Claim
48 words
In a package of the type having a container for housing at least one dry component, the container being adapted to maintain a sterile internal condition while closed, the improvement which comprises means for allowing the introduction of hydrating fluid into the container without compromising internal container sterility.
Claim 5
Dependent Claim
48 words
In a package of the type having a container for housing at least one dry component, the container being adapted to maintain a sterile internal condition while closed, the improvement which comprises means for allowing the introduction of hydrating fluid into the container without compromising internal container sterility.
Claim 6
Dependent Claim
