Abstract
Abstract The invention contemplates a swivel-action container for a paste or the like solid or viscous product having a volatile ingredient. Swivel-action propulsion is achieved by relative rotation of an actuator part and a body part, both of which coact with a product carrier to selectively propel or repel the product via the dispensing end of the container. Full circumferentially continuous seals are achieved between the actuator and body parts, regardless of the extent of product propulsion, and a closure cap for the dispensing end of the body part has circumferentially continuous preloaded sealed engagement to the body part, upon removable snap-engaged assembly thereto. All seal actions are achieved under interference-fit conditions between molded-plastic parts having a degree of compliant deformation to assure seal integrity.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
193 words
A swivel-action dispensing container for a paste product having volatile ingredients, comprising a moldedplastic tubular container body having a cylindrical bore within a body wall and open at one end, said body having a closure-wall formation comprising a relatively thin-walled sEal sleeve concentric within the cylindrical bore and a compliant frusto-conical wall integrally connecting one end of said sleeve to said body wall, whereby said seal sleeve has a degree of compliant yieldability as to its axis orientation with respect to the bore axis, a molded-plastic actuator comprising a bearing portion rotatably received in the sleeve region of said closure wall and integrally including (a) an elongate threaded stem projecting upward with the bore and (b) an externally exposed actuating base, said bearing portion including two circumferentially continuous seal beads having slight interference-fit relation with the bore of said sleeve, a carrier threaded to said threaded portion and having a periphery in guided relation with said body bore, elongate key means coacting between said body bore and said carrier for preventing carrier rotation within said body bore, and a removable closure cap having snap-sealing engagement with the open end of said body wall.
Claim 2
Dependent Claim
193 words
A swivel-action dispensing container for a paste product having volatile ingredients, comprising a moldedplastic tubular container body having a cylindrical bore within a body wall and open at one end, said body having a closure-wall formation comprising a relatively thin-walled sEal sleeve concentric within the cylindrical bore and a compliant frusto-conical wall integrally connecting one end of said sleeve to said body wall, whereby said seal sleeve has a degree of compliant yieldability as to its axis orientation with respect to the bore axis, a molded-plastic actuator comprising a bearing portion rotatably received in the sleeve region of said closure wall and integrally including (a) an elongate threaded stem projecting upward with the bore and (b) an externally exposed actuating base, said bearing portion including two circumferentially continuous seal beads having slight interference-fit relation with the bore of said sleeve, a carrier threaded to said threaded portion and having a periphery in guided relation with said body bore, elongate key means coacting between said body bore and said carrier for preventing carrier rotation within said body bore, and a removable closure cap having snap-sealing engagement with the open end of said body wall.
Claim 3
Dependent Claim
19 words
The container of claim 1, in which said two seal beads are axially spaced and of like radial extent.
Claim 4
Dependent Claim
24 words
The container of claim 1, in which said two seal beads are axially spaced to an extent which exceeds the thickness of said sleeve.
Claim 5
Dependent Claim
40 words
The container of claim 3, in which the outer surface of said sleeve includes a plurality of angularly spaced longitudinal stiffening ribs which extend at least in axial overlap of the span of bead interference contact with the sleeve bore.
Claim 6
Dependent Claim
20 words
The container of claim 4, in which said ribs extend to the location of sleeve suspension by said frusto-conical wall.
Claim 7
Dependent Claim
33 words
The container of claim 1, in which said frustoconical wall extends upwardly and inwardly from the lower end of said body wall, said sleeve projecting downwardly in its suspension from said frusto-conical wall.
Claim 8
Dependent Claim
36 words
The container of claim 6, in which the sleevesuspension limit of said frusto-conical wall includes a circumferentially continuous radially inward retaining flange, said bearing portion of said actuator having a circumferential groove engaged to said flange.
Claim 9
Dependent Claim
55 words
The container of claim 7, in which said actuating base and said body wall have radially overlapping circumferentially continuous adjacent surface formations, the axial locations of said flange and groove being such as to assure a light axially preloaded interference contact of said adjacent surface formations for the engaged relation of said flange and groove.
Claim 10
Dependent Claim
48 words
The container of claim 8, in which said surface formations include at least one circumferentially continuous axially extending bead on the lower axial end of said body wall, the same being axially preloaded into contact with said actuating base for the engaged relation of said flange and stem.
Claim 11
Dependent Claim
29 words
The container of claim 9, in which said axially extending bead is one of two concentric radially spaced beads projecting axially into concurrent preloaded contact with said actuating base.
Claim 12
Dependent Claim
94 words
The container of claim 1, in which the outer surface of said body wall has a radially inward shoulder near the open end and a reduced neck portion extending to said open end, and a circumferentially continuous bead projecting radially outward at a location axially offset from said shoulder, said cap having a bore with an interference fit to said bead and said bore having a bead-receiving groove so spaced from the lower end of said cap that bead engagement in said groove develops a resultant axial compression of said cap against said shoulder.
Claim 13
Dependent Claim
63 words
The container of claim 11, in which the groove surface is of radial section that is arcuate about a center having a first axial offset from the open end of said cap, and in which the bead surface is of radial section that is arcuate about a center having a second axial offset from said shoulder, said first offset exceeding said second offset.
Claim 14
Dependent Claim
44 words
The container of claim 12, in which the arcuate groove radius exceeds the arcuate bead radius, and in which the extent to which said first offset exceeds said second offsEt is greater than the extent to which said groove radius exceeds said bead radius.
