Abstract
Abstract The present invention is an improved sealable vial for storage of materials. The vial includes a tubular body portion sealed at one end and provided with an aperture at the opposite end. The tubular body is further provided with a male spiral thread about the aperture end and a tapered section extending inward from the aperture. A sealing insert is attached to the body for positioning in either a closed position wherein it seals the aperture or an open position wherein the aperture is open. A cap fits over the sealing insert in the closed position and seals the vial. The cap includes female threads which mate with the male threads of the tubular body to secure the closure. The vial is particularly adapted for cryogenic storage of organic samples. The vial is also adaptable to other applications wherein complete sealing is required under wide temperature and pressure range conditions. The improved seals provided by the interface between the sealing insert and the tubular body prevent leakage into or out of the vial.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
71 words
An improved sealable vial compromising: a tubular body sealed at one end and having an aperture formed at the opposite end; a deformable sealing insert attached to the tubular body for mating with the tubular body in the vicinity of said aperture and forming a seal therewith; and a cap for attachment to the tubular body so as to enclose the sealing insert and secure the vial in a closed mode.
Claim 2
Dependent Claim
71 words
An improved sealable vial compromising: a tubular body sealed at one end and having an aperture formed at the opposite end; a deformable sealing insert attached to the tubular body for mating with the tubular body in the vicinity of said aperture and forming a seal therewith; and a cap for attachment to the tubular body so as to enclose the sealing insert and secure the vial in a closed mode.
Claim 3
Dependent Claim
57 words
The vial of claim 1 wherein: the tubular body is in the shape of a cylinder and said seal at one end is provided by a base wall in the shape of a segment of a hollow sphere, with the origin of the sphere situated at a point within the tube on the axis of the tube.
Claim 4
Dependent Claim
51 words
The vial of claim 1 wherein: the tubular body includes first thread means on the exterior thereof about the aperture end; and the cap includes second thread means for mating with said first thread means so as to form a seal therebetween and to secure the cap to the tubular body.
Claim 5
Dependent Claim
40 words
The vial of claim 1 wherein: the tubular body includes a tapered section extending inward from said aperture such that the interior diameter of the tube is greater at said aperture than at the opposite end of the tapered section.
Claim 6
Dependent Claim
31 words
The vial of claim 4 wherein: the sealing insert includes a frustum section adapted for mating with said tapered section of the tubular body so as to form a seal therebetween.
Claim 7
Dependent Claim
38 words
The vial of claim 5 wherein: the sealing insert further includes a wing portion extending about said frustum section for forming a seal with the edge surface of the tube wall of the tubular body about said aperture.
Claim 8
Dependent Claim
55 words
The vial of claim 1, 5 or 6 wherein: the sealing insert is atached to the tublar body by a connecting strip which permits the sealing insert to be moved to and between a closed position, whereby the sealing insert is mated with the tubular body, and an open position, whereby said aperture is unencumbered.
Claim 9
Dependent Claim
26 words
The vial of claim 1 wherein: the cap includes a central depression for forcing the sealing insert into a tight sealing abutment with the tubular body.
Claim 10
Dependent Claim
144 words
The vial of claim 6 wherein: the tubular body includes a first thread means on the exterior surface thereof about the aperture end; the cap includes second thread means on the interior thereof for mating with said first thread means so as to form a seal therebetween and thereby securing the cap to the tubular body; the cap further includes a central depression for forcing the sealing insert into a tight sealing abutment with said tapered section and said edge surface of the tube wall of the tubular body; and the sealing insert is attached to the tubular body by a flexible connecting strip which permits the sealing insert to be moved to and between a closed position, whereby the sealing insert is mated with the tubular body to form a seal about said aperture, and an open position, whereby said aperture is unencumbered.
Claim 11
Dependent Claim
82 words
In a cryogenic vial device including a threaded tube sealed at one end and having an aperture at the opposite end and a threaded cap adapted for mating with the tube, the improvement comprising: a sealing insert attached to the tube, the sealing insert being adapted to mate with the tube in the vicinity of said aperture so as to seal said aperture and the sealing insert being further adapted to be moved to an open position wherein said aperture is unencumbered.
Claim 12
Dependent Claim
82 words
In a cryogenic vial device including a threaded tube sealed at one end and having an aperture at the opposite end and a threaded cap adapted for mating with the tube, the improvement comprising: a sealing insert attached to the tube, the sealing insert being adapted to mate with the tube in the vicinity of said aperture so as to seal said aperture and the sealing insert being further adapted to be moved to an open position wherein said aperture is unencumbered.
Claim 13
Dependent Claim
36 words
The improvement of claim 10 wherein: the tube includes a tapered section extending inward from said aperture; and the sealing insert includes a frustum section for mating with said tapered section to form a seal therebetween.
Claim 14
Dependent Claim
40 words
The improvement of claim 11 wherein: the sealing insert further includes a wing portion about said frustum section, said wing portion being adapted for abutting against the edge of the tube wall about said aperture and forming a seal therewith.
Claim 15
Dependent Claim
26 words
The improved vial of claim 1 or 10 wherein: all components of the vial are constructed of materials having identical response to temperature and pressure gradients.
Claim 16
Dependent Claim
18 words
The improved vial of claim 13 wherein: a single material is used for all components of the vial.
Claim 17
Dependent Claim
11 words
The improved vial of claim 14 wherein: said material is polypropylene.
