Description
- The present invention generally relates to a sanitary cap and a system including the sanitary cap and a sanitary hose. More specifically, the sanitary cap is for a sanitary end, includes, and also includes a base, a flange, a lip, and optionally a breathable insert.
- Sanitary caps are known in the art as products which are used to protect sanitary ends including, but not limited to, stainless steel ends on flex hoses, transfer panels, gas lines, and other ferrules. Conventional sanitary caps are formed from metals and plastics. However, there are a number of disadvantages associated with conventional sanitary caps. In particular, those conventional sanitary caps formed from metals tend to become lodged inside the sanitary ends. Conventional sanitary caps formed from plastics tend to have poor chemical tolerances such that they cannot be easily cleaned, tend to be formed using processes that are not environmentally friendly, tend to absorb moisture, and tend to fail to block particulates and bacteria from entering the sanitary ends. Accordingly, there remains an opportunity to form an improved sanitary cap.
- The present invention provides a sanitary cap and a system including the sanitary cap and a sanitary hose. The sanitary cap includes a base having a peripheral edge. The base also defines a central axis. A flange extends from the peripheral edge along the central axis. A lip spaced from the base extends from the flange inwardly toward the central axis. Additionally, the sanitary cap includes a crosslinked polyethylene foam.
- The present invention also provides a system including a sanitary hose and the sanitary cap. The sanitary hose defines a channel path and has a sanitary end. The sanitary end defines an aperture. The sanitary cap is removably disposed on the sanitary end and comprises a crosslinked polyethylene foam formed in the presence of nitrogen as a physical blowing agent, has a density of from 1 to 20 lb/ft3 at 1 atm, and is a Class VI foam according to the United States Pharmacopeia.
- The present invention further provides a sanitary cap having a base defining a central axis and at least one hole extending through the base. The base also has a peripheral edge. A flange extends from the peripheral edge along the central axis. A ledge, spaced from the base, extends from the flange towards the central axis. A breathable insert is positioned between the ledge and the base, abutting the base. The breathable insert extends over the at least one hole and is gas permeable. A lip spaced from the base extends from the flange inwardly toward the central axis.
- The sanitary cap resists lodging inside of sanitary lines, has excellent chemical tolerance, is environmentally friendly, resists absorbing moisture, and inhibits particulates and bacteria from entering into sanitary lines. The sanitary cap is therefore suitable for protecting sanitary ends on flex hoses, transfer panels, gas lines, and other ferrules.

sanitary cap 20 and asystem 22 including thesanitary cap 20. Thesanitary cap 20 has excellent usability, chemical tolerance, ease of handling, resists absorption of moisture, is environmentally friendly, inhibits movement of particulates and bacteria, and is suitable for applications including, but not limited to, protecting asanitary end 24. - The
sanitary cap 20 includes abase 26, aflange 28, and alip 30. Thebase 26 defines a central axis A and has aperipheral edge 32. In one embodiment theperipheral edge 32 defines a circular configuration about the central axis A as best shown inFIG. 1 . However, it is to be appreciated that theperipheral edge 32 may define any one of a plurality of differently shaped configurations other than a circular configuration. One example of another suitable but non-limiting configuration is a polygonal configuration. - The
flange 28 extends from theperipheral edge 32 along the central axis A as best shown inFIG. 3 . Typically, theflange 28 is disposed substantially perpendicular to thebase 26. Stated differently, theflange 28 is typically spaced from and extends substantially parallel to the central axis A. In one embodiment theflange 28 has adistal end 34 spaced from thebase 26. In this embodiment thelip 30 extends from thedistal end 34 toward the central axis A as best shown inFIGS. 3 , 7, and 12. In another embodiment theflange 28 is spaced from and extends continuously about the central axis A along theperipheral edge 32. In this embodiment theflange 28 is present 360° about the central axis A. In another embodiment thelip 30 extends continuously about the central axis A along thedistal end 34 of theflange 28. In this embodiment thelip 30 is present 360° about the central axis A. However, it is to be appreciated that neither theflange 28 nor thelip 30 are required to extend continuously about the central axis A. - Typically, the
lip 30 is spaced from thebase 26 and extends from theflange 28 inwardly toward the central axis A. In one embodiment thelip 30 extends from theflange 28 substantially parallel to thebase 26. In another embodiment thelip 30 extends to a contact surface spaced from theflange 28 toward the central axis A and tapers in thickness at the contact surface. Thelip 30 may compressably engage thesanitary end 24. Thelip 30 may also ensure formation of a seal between thesanitary cap 20 and thesanitary end 24, thereby preventing particulates and bacteria from entering into thesanitary end 24. In one embodiment the seal formed between thelip 30 and thesanitary cap 20 is a hermetic seal. In another embodiment, thelip 30 also extends from theflange 28 outwardly away from the central axis A. - In one embodiment, the
sanitary cap 20 further includes aledge 60, abreathable insert 62, and the base 26 further defines at least onehole 64 as best shown inFIGS. 13-15 . Typically, the at least onehole 64 extends through thebase 26. In one embodiment, the at least onehole 64 extends along said central axis A and through thebase 26. Theledge 60 is spaced from thebase 26 and extends from theflange 28 towards the central axis A. In one embodiment, theledge 60 extends continuously about the central axis A along theflange 28. In this embodiment theledge 60 is present 360° about the central axis A. However, it is to be appreciated that theledge 60 is not required to extend continuously about the central axis A. Thebreathable insert 62 is positioned between the base 26 and theledge 60. Theledge 60 andbase 26 removably couple thebreathable insert 62 to thesanitary cap 20. Typically, thebreathable insert 62 abuts thebase 26 and extends completely over thehole 64 thereby inhibiting solid particulates from passing through the at least onehole 64. In another embodiment, thesanitary cap 20 is a single unitary structure and is formed from materials that are gas permeable. In yet another embodiment, thesanitary cap 20 is a single unitary structure including sections that are formed from materials that are gas permeable. - Typically, the
breathable insert 62 is formed from materials which are gas permeable but that inhibit transportation of solid particulates and/or liquids. In one embodiment, thebreathable insert 62 is formed from materials which are permeable to water vapor. Examples of suitable materials which are gas permeable include, but are not limited to, polyolefins such as polypropylene and polyethylene including high-density polyethylene fibers commonly known in the art as “Tyvek”, polyvinyl acetate, polyurethanes including aromatic polyether polyurethanes, polyesters, polyamides including nylon, and other foams and/or films that are gas permeable, as recognized in the art. - The embodiment of the
sanitary cap 20 including thebreathable insert 62 is particularly suitable for use where thesanitary end 24 is sterilized and/or cleaned using steam or other vapors. Under these circumstances, thesanitary cap 20 typically forms a seal between thesanitary cap 20 and thesanitary end 24; however, water vapor trapped in thesanitary end 24 can pass through thebreathable insert 62 thereby minimizing collection of moisture within thesanitary end 24. However, thesanitary cap 20, including thebreathable insert 62, still inhibits particulates and bacteria from entering into thesanitary end 24. - The
breathable insert 62 may have one or more of the following physical properties as provided in Table 1 below and/or one or more additional properties not described below. It is also contemplated that thebreathable insert 62 may have one of the properties below but in a range that falls outside of the ranges set forth below. -
