The base and sidewall define a storage area for the ostomy appliance. The base and sidewall are formed from a first material. The cover element extends over the storage area and is formed from a second material. The second material has a higher affinity for the ostomy appliance than the affinity of the first material for the ostomy appliance. The ostomy appliance and the packaging housing are also enclosed.

Description

[Technical field]

[0001] The following description relates generally to packaging housings, and more particularly to packaging housings for adhesive ostomy appliances. [Background technology]

[0002] Adhesive appliances such as barrier rings are packaged and stored in enclosures to maintain the cleanliness and integrity of the appliance. The barrier rings are made of materials that are inherently adhesive or tacky to some degree. A typical enclosure uses a molded clamshell or clamshell-like enclosure or package to secure and hold the appliance (barrier ring). The barrier ring has a release liner on one or both sides of the barrier ring that is a protective cover when the barrier ring is stored in the enclosure.

[0003] To use the barrier ring, the housing is opened, the barrier ring is removed from the housing, the release liner is removed, and the barrier ring is stretched or otherwise contoured to the desired shape.

[0004] While current packaging configurations work well to protect the barrier within the housing, one challenge with such housings is that the user must remove the barrier from the housing prior to use and then remove the release liner from one or both sides of the barrier, which can be problematic in an ostomy care environment where the user is attempting to remove the barrier and apply it to the area around the user's stoma.

[0005] It would therefore be desirable to provide an ostomy barrier ring package that allows for easy removal of the appliance when ready for use. Desirably, such a package would reduce the handling required by the user in preparing and applying the barrier ring. Summary of the Invention

[0006] In one aspect, a packaging housing for an ostomy appliance, such as an adhesive barrier ring, includes a body having a base and an upstanding sidewall integral and continuous with the base. The upstanding sidewall has a periphery opposite the base. The base and sidewall define a storage area for the barrier ring. The base and sidewall are formed from a first material.

[0007] The cover element extends over the storage area on the sidewall periphery. The cover element is formed from a second material different from the first material. The second material has a higher affinity for the ostomy appliance, e.g., a barrier ring, than the affinity of the first material for the ostomy appliance. In this way, the ostomy appliance, e.g., a barrier ring, remains secured to the cover when the cover is removed from the body.

[0008] In one embodiment, the body further includes a seat formed therein and extending upwardly from the base. In an embodiment, the cover element is sealed to the peripheral sidewall. The sidewall may be circular in cross section.

[0009] In one embodiment, for further ease of use, the cover element may include a gripping area extending from an edge of the cover element.

[0010] In one embodiment, the body can be formed of a polymeric material such as polyethylene (PE), polyethylene terephthalate (PET), polypropylene, polyester, polyimide, polyoxymethylene, organosiloxane, or a cellulosic or paper-based material, or a combination thereof. The cover can likewise be formed of a polymeric material such as polyethylene (PE), polyethylene terephthalate (PET), polypropylene, polyester, polyimide, polyoxymethylene, organosiloxane, or a cellulosic or paper-based material, or a combination thereof. Other suitable materials will be recognized by those skilled in the art.

[0011] In another aspect, the ostomy appliance and packaging housing includes an ostomy appliance, such as a barrier ring, having a first surface and a second surface. The ostomy appliance may be formed from an adhesive material.

[0012] In an embodiment, the packaging housing includes a body having a base and an upstanding sidewall integral and continuous with the base. The body has a periphery opposite the base. The base and the sidewall define a storage area for the appliance. The base and the sidewall are formed from a first material.

[0013] The cover element is formed from a second material different from the first material. The ostomy appliance is disposed within the storage area with the first surface disposed on the base and the cover element disposed on the upright sidewall perimeter and in contact with the second surface of the ostomy appliance. The second material has a higher affinity for the ostomy appliance than the affinity of the first material for the ostomy appliance, such that the ostomy appliance, e.g., a barrier ring, remains secured to the cover when the cover is removed from the body. The cover can be sealed to the upright sidewall.

[0014] In an embodiment, the barrier can be formed from a hydrocolloid material. The barrier ring material can further include a ceramide. The packaging housing body can be formed from a polymeric material such as polyethylene (PE), polyethylene terephthalate (PET), polypropylene, polyester, polyimide, polyoxymethylene, organosiloxane, or a cellulosic or paper-based material, or a combination thereof. The cover can likewise be formed from a polymeric material such as polyethylene (PE), polyethylene terephthalate (PET), polypropylene, polyester, polyimide, polyoxymethylene, organosiloxane, or a cellulosic or paper-based material, or a combination thereof. Other suitable materials will be recognized by those skilled in the art.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] One or more embodiments are shown in the drawings and described below, with the understanding that the disclosure can be embodied in various forms, but that the disclosure is to be considered as illustrative and is not intended to be limited to any specific embodiments described or illustrated.

[0018] FIG. 1 illustrates an ostomy appliance such as a barrier ring 10. The barrier ring 10 may be formed from a pressure sensitive adhesive, such as a flexible hydrocolloid material, which may include, for example, a ceramide. The barrier ring 10 may have a first side 12, a second side 14, and an open central region 16. With reference to FIGS. 2-4, the barrier ring 10 may be packaged and stored within a packaging housing 18. In one embodiment, the housing 18 may include a base 20 and an upstanding sidewall 22 having a perimeter 24. The base 20 and the sidewall 22 may define a cup-shaped body 26 having an interior or storage region 28 in which the barrier 10 may be disposed. The base 20 may be formed with an upstanding base 30 such that the open central region 16 of the barrier ring 10 is centered about the base. The barrier ring 10 may be disposed within the housing 18 such that the first side 12 is disposed on the base 20 to define a first interface 32.

[0019] The cover element 34 may have a barrier ring facing surface 36 disposed on the second side 14 of the barrier ring 10 to define a second interface 38. The cover element 34 may extend over the sidewall perimeter 24. In embodiments, the cover 34 may be sealed to the perimeter 24 to close or seal the housing 18. The cover 34 may be formed from a flexible, pliable material, such as a film, that allows the cover 34 to be easily peeled from the housing 18. In embodiments, a portion of the edge of the cover 34 may extend beyond the perimeter 24 to form a gripping area 35.

[0020] To facilitate removal of the barrier ring 10 from the housing 18, the materials of the housing 18 and the cover 34 may be such that the cover 34 has a higher affinity for the material of the barrier ring 10 than the material of the barrier ring 10 has for the material of the housing 18. That is, the barrier ring 10 may have a higher adhesion to the cover 34 than it does to the housing 18. Thus, when the barrier ring 10 is stored in the package 18 and a user pulls the cover 34 off of the housing 18, the barrier ring 10 will be released from the housing 18 while remaining secured to the cover 34. That is, the barrier ring 10 may be released from the housing 18 and pulled away together with the cover 34. The user can then easily remove the barrier ring 10 from the cover 34 and use the ring 10.

[0021] One barrier 10 material may be a flexible hydrocolloid material that may include, for example, ceramide. Thus, in one embodiment, the body 26 may be formed from a polymeric material, such as polyethylene (PE), polyethylene terephthalate (PET), polypropylene, polyester, polyimide, polyoxymethylene, organosiloxane, or a cellulosic or paper-based material, or a combination thereof. Other suitable materials will be recognized by those of skill in the art. The cover 34 may likewise be formed from a polymeric material, such as polyethylene (PE), polyethylene terephthalate (PET), polypropylene, polyester, polyimide, polyoxymethylene, organosiloxane, or a cellulosic or paper-based material, or a combination thereof. Other suitable materials will be recognized by those of skill in the art. In such a configuration, the cover 34 may have a higher affinity for the barrier ring 10 than the body 26 has for the barrier ring 10. In this way, when the cover 34 is removed from the body 26, the barrier ring 10 may remain attached to the cover 34 for ease of handling and use by the user.
