Abstract

A tip cap including a central body extending between a first end and a second end. The first end includes a syringe coupling and the second end can include a projection or pivot. In example embodiments, axial engagement of an end connector of a syringe with the syringe coupling self-connects the tip cap with the end connector of the syringe while rotating about the pivot. According to example embodiments, a flange extends outwardly from the central body to define a width or side-to-side dimension. In example embodiments, the minimum side-to-side dimension is about 1.25 inches.

First claim

What is claimed is:

1. A tip cap comprising:
a body extending from a first end to a second end;
a syringe connector formed at the first end, the syringe connector comprising an outer collar surrounding a male hub, the male hub comprising a recess defined therein and having a floor surface, and an inner surface of the outer collar is threaded; and
a pivot formed at the second end of the body, the pivot generally being centrally-positioned and axially aligned with the male hub so as to provide a hands-free assembly when an end connector of a syringe is forced against the syringe connector;
wherein with the pivot resting against a support surface and with the syringe connector generally positioned upright and extending in a direction away from the support surface, the end connector of the syringe is configured to be engaged with the syringe connector, thereby engaging the end connector with the threaded inner surface of the outer collar, and wherein further engagement of the end connector with the syringe connector is configured to cause a portion of the end connector to slide along the threaded inner surface of the syringe connector so as to cause rotation of the body about the pivot, thereby assembling the tip cap with the end connector of the syringe with a single end connector-to-syringe connector operation.

2. The tip cap of claim 1 , wherein the end connector of the syringe comprises at least one thread portion for engagement with the threaded inner surface of the outer collar of the syringe connector.

3. The tip cap of claim 1 , further comprising a flange extending outwardly from the body, the flange generally positioned between the first and second ends of the body.

4. The tip cap of claim 3 , wherein the flange is configured to provide a seal.

5. The tip cap of claim 1 , wherein the syringe connector is compatible with the ENFit and ISO 80369-3 design standards.

6. A tip cap comprising:
a central body extending between a first end and a second end;
a syringe coupling provided at the first end of the body, the syringe coupling comprising an outer collar having an inner surface defining a threaded surface and a male projection centrally-positioned within the outer collar;
a central projection provided at the second end of the body, the central projection generally extending in a direction substantially opposite the first end; and
a flange portion generally surrounding at least a portion of the central body and generally being positioned between the first and second ends;
wherein with the second end resting atop a support surface, an end connector of a syringe is engageable with the syringe coupling of the first end such that an outwardly-extending lug of the end connector engages with the threaded surface, such that the body is configured to rotate atop the support surface about the central projection such that the syringe coupling of the first end rotatably connects with the end connector of the syringe.

7. The tip cap of claim 6 , wherein the flange portion is substantially cylindrical and outwardly-extends from the central body so as to not pose as a choking hazard.

8. The tip cap of claim 6 , wherein the flange comprises a minimum side-to-side dimension of about 1.25 inches.

9. The tip cap of claim 6 , wherein the syringe connector is compatible with the ENFit and ISO 80369-3 design standards.

10. The tip cap of claim 6 , wherein the flange portion is configured to provide a seal.
