International Classification:

F25D 23/00

US Classification:

62271, 62 85, 62474

Abstract:

A desiccant container () which comprises a generally cylindrically cross-sectioned cup, two dual-density fiberglass discs (), desiccant material (), and a cap (). The cup includes an outer annular portion, an inner tubular portion, and a bottom which connect together to define a space within. The cap () has a planar portion with an aperture for receiving the inner wall portion of the cup and is designed for receipt in the chamber to cover the opening. The cap further includes an outer annular rim portion extending transversely from the planar portion. The peripheral flange portion having tabs with an edge portion which permit the cap to cooperate with the outer wall portion having tabs with an edge portion which permit the cap to cooperate with the outer wall portion so that the cap can be retained within the chamber in one of a number of axially spaced positions to prevent shifting of, and escape of the desiccant.

International Classification:

F26B 19/00

US Classification:

34 85, 34165, 34242

Abstract:

This invention relates to a desiccant cartridge () adapted for use in a canister () of an integrated receiver/dryer or accumulator assembly of an automotive air conditioning system wherein the canister () has an offset inlet port (). The desiccant cartridge () includes a desiccant cup () having a center tube () and a desiccant cap () including a planar portion () having a recessed port area () provided with a first aperture (), or first tube (), for cooperation with a side tube () and/or the offset inlet port () of the canister (). The cap () further includes a docking piece () provided with a second aperture (), or second tube (), for cooperating with the center tube () of the cup () when the cap () is retained therein. Notably, the docking piece () is designed to cooperate with the recessed port area (), preferably via a snap fit, to define a passageway () therebetween so that gas and/or fluid can enter the canister () via the inlet port (), circulate through the desiccant cartridge (), and finally exit via an outlet port ().

Assignee:

Stanhope Products Company - Brookville OH

International Classification:

B65D 3900

US Classification:

220306

Abstract:

A container for particulate desiccant comprises a cup and a cap. The cup includes spaced inner and outer wall portions connected by a transverse web portion to define a chamber having an opening. The cap is designed for receipt in the chamber to cover the opening. In addition, the cap has a hole for receiving the inner wall portion of the cup. The outer wall portion includes a number of nib segments which are arranged into axially spaced nib groupings. The nib segments within each of the nib groupings are circumferentially spaced-apart. The cap includes an edge portion which permits the cap to be retained between axially adjacent nib groupings thus retaining the cap within the chamber in one of a number of axially spaced positions.

Assignee:

Stanhope Products Company - Brookville OH

International Classification:

F26B 2106

US Classification:

34 80

Abstract:

A container is provided for housing desiccant material therein and for facilitating fluid flow therethrough to a surrounding environment. The container comprises a cup member including a base or bottom wall member and a generally cylindrically shaped outer wall connected to the base or bottom wall member to thereby define a housing. A plurality of openings extend through the outer wall and provide communication between the housing and the surrounding environment. At least one recessed, relief portion is provided in communication with one of the openings. The recessed, relief portion has an outer diameter dimension less than the outer diameter dimension of the cup member. Accordingly, when the cup is snugly received in an associated canister or the like, a relief area is formed that defines a fluid flow channel along the interface of the cup member and canister.

International Classification:

B01D 5304

US Classification:

96135

Abstract:

A container for particulate desiccant comprises a cup and a cap. The cup includes spaced inner and outer wall portions connected by a transverse web portion to define a chamber having an opening for receiving the desiccant. The cap is designed for receipt in the chamber to cover the opening. In addition, the cap has a hole for receiving the inner wall portion of the cup. The inner wall portion includes a stepped inner surface defining an intermediate flange for preventing a canister pipe from passing completely through the inner wall portion. The inner wall portion also includes a beveled inner end surface which tapers radially inwardly in a direction toward the transverse web portion to facilitate insertion of the canister pipe into the inner wall portion. An inner wall extension portion is coaxially joined with the inner wall portion at a web side of the cup to facilitate return of dehydrated air or fluid to an air conditioning system. The canister pipe, inner wall portion and inner wall extension portion cooperate to define a return passage for the dehydrated air or fluid that passes over the desiccant in the chamber.
