Abstract
The field of the invention is site-specific drug delivery capsules (SSDC's). The disclosure relates to a closure member () for a substance reservoir () of an SSDC (). The SSDC () includes a retainer that provides a non-linear force resisting opening of the closure member (). The non-linear force ensures that the closure member () unseals the reservoir () only when an opening force exceeds a maximal value of the resisting force, thereby preventing premature or accidental emptying of the reservoir (). The preferred means of providing the resistive force is a rolling, elastomeric o-ring () that additionally seals the closure member () into an aperture ().
