Abstract

Closure mechanisms and seal integrity indicators for sterilization containers are provided. For example, a closure mechanism comprising at least one handle and at least two arms is provided with a sterilization container lid to apply a more uniform or evenly distributed force to a container gasket. A container body defines an inner lip on which the gasket and lid are received such that the sealing interface is recessed within the container. Further, a seal indicator may indicate whether the container is sufficiently sealed to prevent an ingress of contaminants into the container. If the container is sufficiently sealed, the seal indicator is visible, but if not, the seal indicator is not visible. Thus, the seal indicator undergoes a change in state when the sterilization container transitions from unsealed to sealed, or vice versa, such that a user may ascertain whether the container is properly sealed to maintain the container's sterility.

Claims (47)

1. A sterilization container, comprising:

a body including a first end, a second end opposite the first end, a first side extending between the first and second ends, and a second side opposite the first side and extending between the first and second ends, the body further including an open top portion;

a lid, the body and the lid together defining an interior, the lid having a closure mechanism that includes at least two arms, the at least two arms configured to protrude through the lid and the body to secure the lid to the body; and

a gasket for sealing the interior against an ingress of contaminants.

2. The sterilization container of claim 1 , further comprising:

a filter extending across the open top portion of the body from the first end to the second end and from the first side to the second side,

wherein the gasket and filter are integrally formed as a single piece gasket/filter.

3. The sterilization container of claim 1 , wherein the body defines an inner lip around an inner surface of the body within the interior of the container, the inner lip recessed vertically inward within the body.

4. The sterilization container of claim 3 , wherein the gasket is disposed on the inner lip.

5. The sterilization container of claim 3 , wherein the lid is supported by the inner lip such that the lid is recessed within the body.

6. The sterilization container of claim 5 , wherein a rim of the body extends around the inner lip and has a vertical height h over the inner lip, and

wherein at least two rim openings are defined in the rim, each rim opening configured for receipt of a distal end of one of the at least two arms.

7. The sterilization container of claim 3 , wherein the gasket is disposed on the inner lip, and

wherein the lid is configured to be supported by the inner lip such that the lid is recessed within the body with the gasket disposed between the lid and the inner lip.

8. The sterilization container of claim 7 , wherein a rim of the body extends around the inner lip and has a vertical height h over the inner lip, and

wherein at least two rim openings are defined in the rim, each rim opening configured for receipt of a distal end of one of the at least two arms.

9. The sterilization container of claim 1 , further comprising:

a seal indicator for indicating a seal state of the sterilization container, the seal indicator having a first indicator state that indicates an unsealed container state and a second indicator state that indicates a sealed container state,

wherein the seal indicator is in the first indicator state when the gasket is not compressed to seal the sterilization container against the ingress of contaminants, and

wherein the seal indicator is in the second indicator state when the gasket is compressed to seal the sterilization container against the ingress of contaminants.

10. The sterilization container of claim 9 , wherein the seal indicator is not visible in the first indicator state and is visible in the second indicator state.

11. The sterilization container of claim 9 , wherein the seal indicator is visible from an exterior of the sterilization container through an opening in the body.

12. The sterilization container of claim 1 , wherein the gasket extends about a perimeter of the body and the lid, the gasket disposed between the body and the lid.

13. The sterilization container of claim 1 , further comprising:

a safety cover that fits over a raised portion of the lid,

wherein the safety cover defines a passageway to allow a fluid to pass from an exterior of the container to the interior.

14. The sterilization container of claim 13 , wherein the passageway is a plurality of openings, wherein a first portion of the plurality of openings are defined in a top surface of the safety cover, and wherein a second portion of the plurality of openings are defined along a side surface of the safety cover.

15. The sterilization container of claim 1 , wherein at least the distal end of each has a color that contrasts with a color of the lid and a color of the body.

16. A sterilization container, comprising:

a body including a first end, a second end opposite the first end, a first side extending between the first and second ends, and a second side opposite the first side and extending between the first and second ends, the body further including an open top portion;

a lid, the body and the lid together defining an interior, the lid having a raised portion defining a plurality of vent openings;

a gasket for sealing the interior against an ingress of contaminants, the gasket disposed between the body and the lid; and

a safety cover that fits over the raised portion of the lid,

wherein the safety cover defines a passageway to allow a fluid to pass from an exterior of the container to the interior via the passageway and the plurality of vent openings.

17. The sterilization container of claim 16 , wherein the passageway is a gap defined between the safety cover and the raised portion of the lid.

18. The sterilization container of claim 16 , wherein the lid comprises a closure mechanism that includes at least two arms, the at least two arms configured to protrude through the lid and the body to secure the lid to the body, and wherein the body comprises an inner lip defined around an inner surface of the body, the lid received on the inner lip such that the lid is recessed within the body.

19. The sterilization container of claim 16 , further comprising:

a seal indicator for indicating a seal state of the sterilization container, the seal indicator having a first indicator state that indicates an unsealed container state and a second indicator state that indicates a sealed container state,

wherein the seal indicator is in the first indicator state when the gasket is not compressed to seal the sterilization container against the ingress of contaminants, and

wherein the seal indicator is in the second indicator state when the gasket is compressed to seal the sterilization container against the ingress of contaminants.

20. A sterilization container, comprising:

a body including a first end, a second end opposite the first end, a first side extending between the first and second ends, and a second side opposite the first side and extending between the first and second ends, the body further including an open top portion;

a lid, the body and lid together defining an interior;

a gasket for sealing the interior against an ingress of contaminants, the gasket disposed between the body and the lid; and

a seal indicator for indicating a seal state of the sterilization container, the seal indicator having a first indicator state that indicates an unsealed container state and a second indicator state that indicates a sealed container state,

wherein the seal indicator is in the first indicator state when the gasket is not compressed to seal the sterilization container against the ingress of contaminants, and

wherein the seal indicator is in the second indicator state when the gasket is compressed to seal the sterilization container against the ingress of contaminants.
