In a non-limiting example, retainer ring 68 is or the polypropylene including 30% glass-filled, although any other polymer, altogether Combination of polymers, polymer etc. is also equally acceptable.In other embodiments, retainer ring 68 is metal.In addition, retainer ring 68 It can be formed transparent, translucent or semi-transparent to promote the observation to the content in cup holder 60 (Fig. 3).Other The material in embodiment, being used to form (for example, molding) retainer ring 68 may include the dyestuff for being selected to provide required color Or pigment.

Fig. 2 is returned to, capping main body 70 generally includes to promote to be filled with the feature to form completed capping 62 with 68 groups of retainer ring Portion；Promote the features of completed capping 62 and the close installation of liquid of cup holder 60 and lining 64 in the case where cooperating with retainer ring 68；With And promote the features connecting with connector 54 (for example, first linking format 74).In order to according to retainer ring 68 as described above more The relationship being fully understood by between completed capping 62 and cup holder 60, is described in detail below the character pair of capping main body 68 Portion then explains in detail the first linking format 74 and connector 54.

Capping main body 70 is shown in greater detail in Fig. 7 and (generality mentions including jet pipe 72 and the first linking format 74 And).In addition, capping main body 70 include wall 200, edge 202, skirt 204, one or more liner seal component 206 with And flange retention features portion 208.Wall 200 limit outside 210 and the inner face opposite with outside 210 (in Fig. 7 hide, but It is shown in Fig. 9 D with 212).Outside 210 can have bending or dome shape shape as shown in the figure, although other shapes and geometry knot Structure is also acceptable (for example, taper).Outside 210 extends to the first linking format 74 and jet pipe 72 from edge 202.Edge 202 protrude outward from the peripheral radial of wall 200.Skirt 204 is longitudinally projecting from edge 202.Liner seal component 206 is from skirt One or more ribs that shape portion 204 projects radially outwardly, reason clearly illustrate below.

Flange retention features portion 208 can respectively be similar to fingers or door bolt outstanding on 210 and outside 210 from the outside Lock, and be provided commonly for keeping retainer ring 68 (Fig. 2).For example, Fig. 8 A and Fig. 8 B show the retainer ring when forming completed capping 62 68 arrive the final assembling of capping main body 70.Ring 140 is slidably located on wall 200 and edge 202, and flange keeps special 208 collective effect of sign portion is to capture retainer ring 68 relative to capping main body 70.In the embodiment illustrated, in 140 He of retainer ring ring Rotation or sliding interface are established between flange retention features portion 208, to allow retainer ring 68 (anti-relative to the capping rotation of main body 70 ).Retainer ring 68 relative to capping main body 70 rotation by is provided with retainer ring 68 flange rotation limited features portion 162 and Corresponding flange in flange retention features portion 208 keeps the selectivity between features adjacent or the limitation of handover.Using this Construction, retainer ring 68 can rotate freely (vice versa) relative to capping main body 70 in the first rotational direction, until flange rotates Limited features portion 162 is contacted with one adjoining of correspondence in flange retention features portion 208；Attempting in a first direction further In the case where rotating retainer ring 68, capping main body 70 will rotate together with retainer ring 68.

The cross section diagram of the capping 62 of Fig. 8 B is shown, in final assembling of the retainer ring 68 to capping main body 70, tab 144 extend far from edge 202, and are radially spaced apart with hub 204.In each of capping engagement member 170 and skirt Interstice coverage or gap 220 are established between portion 204.Interstice coverage 220 be provided be conducive to will cover 62 be installed to glass holder 60 (scheme 2)。

More specifically, arrangement of Fig. 9 A reflection capping 62 before being installed to glass holder 60.As a reference point, lining 64 is set It sets in cup holder 60, and therefore major part is hidden in the view；The edge 66 of lining 64 is partially visible and in figure 9 a It is identified.Retainer ring 68 is rotatably arranged relative to cup holder 60 so that each of tab 144 usually with cup holder 60 Correspondence one (two therein are usually identified in Fig. 9 A) alignment in gap 130 between holder engagement member 122.Capping 62 Then it can be lowered on glass holder 60, as shown in Figure 9 B.In this regard, due in tab 144 and gap 130 (Fig. 9 A) Respective clearance alignment, therefore by each of tab 144 carrying capping engagement member 170 (Fig. 5) holder engage structure Freely pass through between part 122.Before the cam surface engagement on any part, capping 62 is substantially completely against cup holder 60 (and/or lining 64) placement, although not yet disposing and tightening completely." buckle " feels and/or sound source is in the group of following item Close: (i) liner seal component 206 (Fig. 9 A) is rapidly advanced in the open end of lining 64, so that a part of lining 64 is fast Fast ground is stretched on liner seal component 206 and is then relaxed；And (ii) 62 is rapidly fallen to be connect when capping When touching, capping body edge is along the corresponding 66/ holder edge 118 of Ground shock waves lining edge 202 (Fig. 7).Pass through the segmentation structure of retainer ring 68 It makes (that is, recess 158 and corresponding flange open 166) and further promotes " buckle " feeling or sound.If retainer ring 68 is not divided Section, then far less likely to occur buckle is felt, so that user be allowed undesirably " excessively to tighten " or capping 62 is screwed into lining In 64, and may folded liner 64 while doing so.This brief buckle feeling can allow in tactile and/or acoustically End user firmly believes that capping 62 and lining 64 are firmly attached, although capping 62 is not yet fixed to cup holder 60.

Then, retainer ring 68 can rotate (and/or vice versa) relative to cup holder 60, cover engagement member 170 to realize Engagement between holder engagement member corresponding with holder engagement member 122.For example, the broken section of Fig. 9 C illustrate with Retainer ring 68 is rotated relative to cup holder 60, between one in holder engagement member 122 and one in capping engagement member 170 Initial handover.With initial rotation, the front end 172 for covering engagement member 170 is led towards the front end of holder engagement member 122 124 To.In the placement arrangement that capping 62 as mentioned in the previous paragraph is placed in 60 top of glass holder and is installed to lining 64 (Fig. 2), capping The front end 172 of engagement member 170 is located at the vertical position along central axis A, which deviates or the engagement of " being lower than " holder The front end 124 of component 122.Therefore, further rotating with retainer ring 68, capping engagement member 170 are easily engaged in holder Component 122 " lower section " passes through.However, the further rotating relative to cup holder 60 with retainer ring 68, holder engagement member 122 The cam face 176 of cam face 128 and capping engagement member 170 directly joins.Specifically, continue to revolve with retainer ring 68 Turn, the clamping applied along central axis A is realized in the cam-like handover between holder engagement member 122 and capping engagement member 170 Power.Therefore, capping 62 and cup holder 60 are realized along the clamping movement of central axis A by the rotation of retainer ring 68, with preferably really Protect securely connection.In addition, as shown, holder engagement member 122 and capping engagement member 170 are as the partial threads easily started Optional setting can not only make the installation of capping 62 faster, but also possible cross threading can be prevented, reducing amount of paint can gather Collect and make dirty the quantity in the region of component, and keeps cleaning transfiguration easy.

Fig. 9 D is reflected in form completed reservoir 52 during capping 62 when being ultimately connected to glass holder 60, lining Edge 66 is clamped between holder edge 118 and capping edge 202, to provide hydraulic seal.Lining 64 be also stretched or It is clamped between liner seal component 206 and cup holder 60, the liquid-tight seal between capping 62 and lining 64 is further promoted to close System.Using this sealing arrangement, be arranged in the liquid in lining 64 (for example, paint) by from lining 64 along cover wall 200 Face 212 flows to jet pipe 72 (for example, when reservoir 52 is inverted from the orientation of Fig. 9 D).Individual retainer ring 68 may be movably coupled to Main body 70 is covered, and does not have to the leak path for worrying to generate paint.

In some embodiments, capping main body 70 can be formed by polymer material or plastic material, and can be molding Component.In a non-limiting example, capping main body 70 is or including polypropylene, although any other polymer, copolymer, Combination of polymer etc. is also equally acceptable.In other embodiments, capping main body 70 is metal.In addition, capping master Body 70 can be formed transparent, translucent or semi-transparent to promote the observation to the content in cup holder 60.Other The material in embodiment, being used to form (for example, molding) capping main body 70 may include being selected to provide required color Dyestuff or pigment.

Fig. 7 is returned to, the first linking format 74 (generality refers in Fig. 7) includes that platform 250, first keeps structure 252a Structure 252b is kept with second.In general, platform 250 and holding structure 252a, 252b shape at the position outside jet pipe 72 It is protruded in the outside of cover wall 200 210 or from the outside of cover wall 200 210, and is configured to be conducive to and connect jointly 76 (Fig. 2) selective connection of the second linking format of complementation of first 54 (Fig. 2) or installation.

Platform 250 terminates at or limits the guide surface 260 rotated around jet pipe 72.Such as institute best in Figure 10 A to Figure 10 C Show, the geometry of guide surface 260 can be considered as providing by the first and second undercutting or capture region 264a, what 264b was separated First guide section and the second guide section 262a, 262b.Relative to by guide surface 260 around jet pipe 72 rotation (clockwise or The direction of rotation limited counterclockwise), the first guide section 262a are circumferentially extended from the first undercutting 264a to the in the clockwise direction Two undercutting 264b, and there is the geometry for generating introduce region 266 and sloped region 268.Then, relative to side clockwise To introduce region 266 is in " front " or " upstream " of sloped region 268.Similarly, the second guide section 262b can be considered as suitable It is circumferentially extended from the second undercutting 264b to the first undercutting 264a on clockwise, and has and generate introduce region 266 and slope The geometry in region 268.

In some embodiments, guide section 262a, 262b can be substantially the same so as to the first guide section 262a with Lower description is equally applicable to the second guide section 262b.First guide section 262a is positioned to keep structure 252a corresponding with first.Draw Enter region 266 principal plane can for it is substantially flat (that is, and completely flat shape deviation within 5%) and substantially hang down Directly in (that is, and complete vertical relation deviation within 5%) central axis A.Sloped region 268 from introduce region 266 to On the extending direction of second undercutting 264b longitudinal downward tapered (upright orientation relative to Figure 10 B and Figure 10 C), thus forming portion Divide spiral-shaped.Therefore, introduce region 266 longitudinally or vertically " is higher than " sloped region 268 (relative to Figure 10 A and Figure 10 B Upright orientation), and the principal plane of sloped region 268 favours the principal plane of introduce region 266 and (and is not substantially perpendicular In central axis A).Transition wire or area 270 are limited at the point of intersection of introduce region 266 and sloped region 268, and substantially with First keeps structure 252a alignment.Transition wire 270 (and transition wire 270 associated with the second guide section 262b) is Figure 11's It is more clear in cross-sectional view obvious.

Continue to refer to figure 11, guide surface 260 can be relative to modified or inhomogenous radially-wide of central axis A Degree.It can be that circular (cylindrical for following jet pipe 72) realizes inhomogenous by the inward flange 280 of guide surface 260 Radial width, and the opposite outer edges 282 of guide surface 260 have inhomogenous shape.For example, along the first guide section 262a's The shape (top plan view relative to Figure 11) of the outer edge 282 of introduce region 266 is undercuting 264a towards slope from first There can be incremental radius on the extending direction in region 268.In addition, along sloped region 268 outer edge 282 shape at least There can be incremental radius on the extending direction of one Duan Chao second undercutting 264b.Using this optional configuration, in the second undercutting At 264b, the radial width of the first guide section sloped region 268 is greater than the radial width of the second guide section introduce region 266；Phase As, at the first undercutting 264a, the radial width of the second guide section sloped region 268 is greater than the first guide section introduce region 266 radial width.

First undercutting 264a and the second undercutting 264b can be substantially the same, and can be equally spaced around jet pipe 72. It is provided by the geometrical characteristic portion that the first undercutting 264a is generated by the enlarged drawing of Figure 12.It is consistent with above description, the first undercutting 264a The mistake for being formed in or limiting between the sloped region 268 of the second guide section 262b and the introduce region 266 of the first guide section 262a It crosses.Shoulder keeps features 290 to be limited by undercuting 264a, the front end 292 and the second guide section in the first guide section 262a Extend between the rear end 294 of 262b.The principal plane of shoulder 290 relative to introduce region 266 principal plane and relative to sloped region The principal plane in domain 268 is not parallel, and wherein shoulder 290 is above second segment sloped region 268 relative to the upright orientation of Figure 12) to Outer protrusion.

Fig. 7 and Figure 12 is generally illustrated in some embodiments, the outside for being partially project into wall 200 of guide surface 260 Reflect the inclined of the continuous shape of the outside 210 of wall 200 in 210 continuous shape (for example, dome shape shape) or in other ways Difference.The plane of the cross-sectional view of Figure 13 passes through the first undercutting 264a, and preferably reflects the optional feature portion.As shown, outer Face 210 is from platform 250 towards having continuous tilt shape (such as dome shape shape, cone shape on the extending direction at edge 202 Shape etc.).The sloped region 268 of second guide section 262b interrupts the continuous shape, wherein shape of the rear end 294 relative to outside 210 Shape is internally positioned.In other words, in some embodiments, platform 250 can be considered as prominent from the outside of wall 200 210, wherein Guide surface 260 is mainly limited by platform 250 and is partly limited by outside 210.Alternatively, and Figure 10 B and figure are referred to Between 13, capping main body 70 can be considered as including the platform 250 at least partly around jet pipe 72.Platform 250 includes or forms At least one region (for example, introduce region 266), the region are used as the top of platform 250 (relative to Figure 10 B and Figure 13 Upright orientation), and it is number of substantially flat, to limit the principal plane M of platform 250.Platform 250 further includes or is formed at least One region (for example, sloped region 268), the region have the central axis for tilting and surrounding jet pipe 72 relative to principal plane M The partial helical shape of line C rotation.Adjoin platform 250 and including the principal plane M relative to platform 250 in the outside 210 of wall 200 Inclined part (generally with 296 marks in Figure 10 B and Figure 13).The outside of dilapidated walls 200 in the partial helical shape of platform 250 210 sloping portion 296.Sloping portion 296 can limit or including dome shape, conical by its shape etc..The of partial helical shape Transition region (for example, transition wire 270 in Figure 10 A) of the one end close to principal plane M, and opposite second of partial helical shape Hold the sloping portion 296 of the outside 210 of dilapidated walls 200 in (for example, rear end 294).In some embodiments, partial helical shape Second end (for example, rear end 294) terminate at holding features, such as one in undercutting 264a, 264b.Utilize these structures It makes, the total height of capping main body 70 (and therefore covering 62 (Fig. 2)) reduces (compared with conventional lance connector format), thus Cup holder 60 (Fig. 2) is positioned closer to spray gun 32 (Fig. 1) in a manner of meeting ergonomics during use.

Fig. 7 is returned to, structure 252a is kept, 252b can be identical, so that same to being described below for the first holding structure 252a Structure 252b is kept suitable for second.First keeps structure 252a associated with the first segment 262a of guide surface 260, and wraps Include arm 300 and tab 302.Arm 300 is radially spaced with jet pipe 72, and is protruded axially upwards from wall 200.Ribs 304 is appointed Selection of land is arranged between arm 300a and wall 200, for deflection of the control arm 300 far from jet pipe 72 during use.Tab 302 from The arm 300 opposite with wall 200 radially-inwardly protrudes.

With reference to Figure 14 A, the first holding structure 252a can be considered as limiting opposite arrival end 310 and outlet end 312.Relatively In above-mentioned direction of rotation, " front " or " upstream " of the arrival end 310 in outlet end 312.The cross-sectional view of Figure 14 B and Figure 14 C also show Capture region 314 is limited by the first guide section 262a, arm 300 and tab 302 out, for receiving the second linking format 76 (Fig. 2) Character pair portion.

More specifically, the protruding portion of arm 300 limits surface of shell 320.Outside of the surface of shell 320 towards jet pipe 72 and with The outer radial of jet pipe is spaced apart.Tab 302 is radially-inwardly protruded relative to surface of shell 320, and limits engagement surface 322 With alignment surface 324.Engagement surface 322 is opened towards the first guide section 262a and with the first guide section 262a longitudinal gap.It is right Quasi- surface 324 is spaced apart towards jet pipe 72, and with the outer radial of jet pipe.Between jet pipe 72 and engagement surface 322 and spray The size of radial spacing between pipe 72 and alignment surface is corresponding with the geometrical characteristic portion of connector 54 (Fig. 2).

The geometry of first guide section 262a and engagement surface 76 is configured to be conducive to and 76 (figure of the second linking format 2) the wedge-shaped of character pair portion is engaged by locking.Referring in particular to Figure 14 C, tab 302a generally with introduce region 266 and slope Transition wire 270 between region 268 is aligned.The shape of engagement surface 322 limits wedging section 330 and optional gap section 332. It wedges section 330 to extend from arrival end 310, and is aligned or is arranged on introduce region 266 with introduce region 266.Gap Section 332 extends to outlet end 312 from wedging section 330, and is aligned or is arranged in sloped region 268 with sloped region 268 On.The intersection point of wedging section 330 and gap section 332 is generally aligned with transition wire 270.Engagement surface 322 is along wedging area The principal plane and the principal plane along gap section 332 of section 330 are non-coplanar.

Fig. 2 is returned to, the second linking format 76 is configured to as described above the selectively feature with the first linking format 74 Portion's cooperation, and it is arranged to a part of connector 54 in some embodiments.With reference to Figure 15 A to Figure 15 D, in addition to the second company It connects except format 76 (generality refers in Figure 15 A), connector 54 also typically includes tubular element 350.Tubular element 350 can wrap The features for being similar to conventional lance reservoir-adapter are included or provide, such as establishing the connection for arriving the ingress port of spray gun. In consideration of it, various forms can be presented in tubular element 350, and limit center channel 352.Access 352 is in tubular element It is open at 350 front end 354.It is conducive to be assembled into conventional (for example, screw thread) spray gun in addition, tubular element 350 is formed or is provided with The mounting characteristic portion of ingress port.For example, external screw-thread 356 can be arranged along the external of the tubular element 350 of adjacent front end 354, Be configured to and be provided with gun inlets port is threaded through screw thread handover.In this regard, the spiral shell of external screw-thread 356 It can be selected according to the associated specific thread pattern of the brand/model of spray gun used is intended with connector 54 away from, profile and spacing It selects.Other spray gun mounting characteristics portion is equally acceptable, may include or needs or may not include or need external screw-thread 356. Tubular element 350 optionally further include or limit grasp section 358.Grasping section 358, which is configured to be conducive to user, to be made Connector 54 is manipulated with conventional tool, and in some embodiments, includes or defines and be suitable for passing through what spanner easily engaged Hexagonal surface's pattern.In other embodiments, grasping section 358 can omit.

Second linking format 76 includes pedestal 360, the first locking structure 362a, the second locking structure 362b and tracing surface 364.Pedestal 360 is prominent from tubular element 350, and carries or formed locking structure 362a, 362b and tracing surface 264.Locking knot Structure 362a, locking structure 362b are configured to selectively keep structure with corresponding in holding structure 252a, 252b (Fig. 7) again Handover, and tracing surface 364 is configured to join with guide surface 260 (Fig. 7) as described below.

Pedestal 360 includes shoulder 370 and ring 372.As best seen in Figure 15 E, shoulder 370 and the combination of ring 372 are to limit Room 374, the room 374 lead to the access 352 of tubular element 350 and are configured to receive jet pipe 72 (Fig. 2).Shoulder 370 is from pipe Shape component 350 radially outwardly and downwardly extends.Ring 372 is on the direction opposite with tubular element 350 from the outer periphery of shoulder 370 It is longitudinally projecting, and terminate at tracing surface 364.In addition, ring 372 limits the cylindrical inner face 380 opposite with outside 382.Ring 372 Internal diameter (for example, the diameter limited by cylindrical inner face 380) corresponds to the outer diameter of (for example, approximate or be slightly larger than) jet pipe 72. In some embodiments, ring 372 can limit along inner face 380 or provide joint sealing surface 284, with jet pipe sealing surfaces 342 (Figure 14 B) are corresponding.The outer diameter of ring 372 can change on the extending direction towards tracing surface 364 as described below, Huo Zheke It is uniform.Anyway, select ring 372 maximum outside diameter (for example, the maximum gauge limited by outside 382) be nested in by Structure 252a is kept, in the aperture diameter that 252b (Fig. 7) is established jointly, as described below.

The geometry of the shape of tracing surface 364 with above in relation to capping guide surface 260 (Fig. 7) described in geometry knot Structure is consistent.Specifically, and Figure 15 F is referred to, tracing surface 364 can be considered as providing or generating by the first and second undercutting or capture The the first orbital segment 390a and the second orbital segment 390b that region 392a, 392b are separated.Undercut 392a, the circumferential position and shape of 392b Undercutting 264a, 264b (Fig. 7) in shape and capping main body 70 (Fig. 7) as described above is corresponding.The shape of orbital segment 390a, 390b Shape and geometry and guide section 262a as described above, 262b (Fig. 7) are corresponding.Thus, for example, orbital segment 390a, 390b It can respectively be considered as generating introduce region 394 and sloped region 396 (identifying for the first orbital segment 390a in Figure 15 F). 392a is undercut, transition position of the shape of 392b between orbital segment 390a, 390b establishes fingers or keep features 400.Example Such as, as shown in fig. 15f, the fingers 400 at the second undercutting 392b are limited in the front end 402 and first of the second orbital segment 390b Extend between the rear end 404 of orbital segment 390a.

In some embodiments, locking structure 362a, 362b are identical so as to the first locking structure 362a with Lower description is equally applicable to the second locking structure 362b.Locking structure 362a along the direction that ring 372 circumferentially extends limit with The opposite first end 420 of second end 422, such as the best finding of Figure 15 B.In addition, locking structure 362a is limited from the protruding portion of ring 372 Or the adjacent surface 424 opposite with above 426 is formed, and the guide surface 428 as most preferably identified in Figure 15 E.The shape of adjacent surface 424 Shape follows the corresponding part of tracing surface 364 or connects with the corresponding part of tracing surface 364.For example, and such as the best institute of Figure 15 F See, at first end 420, first orbital segment 390a intersection of the adjacent surface 424 among sloped region 396.From first end 420 On the direction of extension, the angled or part helix orientation of sloped region 396 is imitated or followed to the shape of adjacent surface 424；In addition, Introduce region 394 is imitated or followed to the shape of adjacent surface 424 to the substantially flat of second end 422 or the shape of plane.

With specific reference to Figure 15 C, above 426 be formed as longitudinally opposed with adjacent surface 424, to limit the height of locking structure 362a Degree.In some embodiments, 426 plane or shape change between first end 420 and second end 422 above, thus shape At locking structure 362a to provide insertion section 440, locking section 442 and optional tail portion section 444.Being inserted into section 440 includes With the principal plane of the principal plane of the corresponding region of adjacent surface 424 the upper surface of not parallel 426 so that locking structure 362a is in first end There is reduced height at 420.In other words, the height of locking structure 362a from the direction that first end 420 extends along insert Enter the increase of section 440.In some embodiments, inclined-plane can be formed in above in 426 at first end 420, and above 426 Along insertion section 440 remainder is number of substantially flat or plane, be arranged to not parallel with adjacent surface 424.Above 426 It is roughly parallel to the corresponding region along locking section 442 of adjacent surface 424, and is generated relative to ring 372 and is similar to part spiral shell (locking section 442 associated with the second locking structure 362b is identified the shape or geometry of rotation in Figure 15 A, the figure Partial helical shape is also shown).Tail portion section 444 may include adjacent surface 424 and above 426, they are towards (the figure of second end 422 It is substantially parallel on extending direction 15B).Using this construction, locking structure 362a relative to central axis A vertical position with Locking structure 362a around ring 372 rotate and change, wherein first end 420 is vertically " low relative to the upright orientation of view In " second end 422.

The best finding such as in Figure 15 B, the radial width of locking structure 362a is by the diameter between ring 372 and guide surface 428 It is limited to the distance of (relative to central axis A).In consideration of it, locking structure 362a can have relative to central axis A Variation or inhomogenous radial width.For example, the shape (top plan view relative to Figure 15 D) of guide surface 428 is from Radius that is uniform or being slightly increased can be limited on the direction that one end 420 extends, and to the tapered of second end 422 or reduce half Diameter, to form streamlined appearance.

In some embodiments, the shape of locking structure 362a is further drawn with ring 372 by insert or recess 450 Boundary, and be more exactly shaped relative to ring 372, insert or recess 450 can be formed in the ring 372 adjacent to locking structure 362a Face in and optional groove 452, as Figure 15 A is identified.Anyway, locking structure 362a, 362b surround 372 cloth of ring It sets, so that space characteristics portion is in identical direction of rotation relative to central axis A.For example, the orientation relative to Figure 15 B, often The vertical lower first end 420 of a locking structure 362a, 362b are in the clockwise direction rotatably corresponding vertical higher Second end 422 " front ".

In some embodiments, connector 54 is formed by rigid material such as stainless steel (303S31).It is contemplated that other materials Material, such as plastics.The composite material or other materials being used together with specific coating material and/or application are also acceptable.

The connection of reservoir 52 and connector 54 starts from the alignment of ring 372 Yu jet pipe 72, as shown in figure 16.In the cloth of Figure 16 In setting, connector 54 is rotatably arranged so that locking structure 362a, 362b are rotationally offset from and keeps structure 252a, 252b.So Connector 54 is directed in capping main body 70 (and/or vice versa) afterwards, wherein jet pipe 72 is nested in pedestal 360.

Under the initial assembled state of Figure 17 A and Figure 17 B, connector 54 is placed to as already identified above in capping main body 70, Wherein locking structure 362a, 362b are rotatably spaced apart with structure 252a, 252b is kept.Figure 17 C also illustrates connector 54 initial Relative to the rotation arrangement of capping main body 70 when placement.Relative to clockwise direction, the first end 420 of the first locking structure 362a In " front " of the arrival end 310 that first keeps structure 252a, and the first end 420 of the second locking structure 362b is protected second Hold " front " of the arrival end 310 of structure 252b.The radial width of the increase of locking structure 362a, 362b promotes user initial Connector 54 is placed into capping main body 70 by the rotation position shown in.Return to Figure 17 A and Figure 17 B, the tracing surface 364 of connector 54 Section against capping main body 70 guide surface 260.For example, the cross section of Figure 17 D shows the slope of the first orbital segment 390a Sloped region 268 of a part in region 396 against the first guide section 262a.Due to as described above along the guiding of capping main body 70 Section 262a, the partial helical shape of 262b and orbital segment 390a, 390b along connector 54, connector 54 and capping main body 70 it Between this initial contact state under, Figure 17 A reflect locking structure 362a, 362b be positioned vertically within keep structure 252a, 252b Each of capture region 314 (in Figure 17 A hide) " top " (orientation relative to Figure 17 A).

Then, connector 54 rotates (and/or vice versa) relative to capping main body 70, thus guiding locking structure 362a, Each of 362b and the corresponding holding structure engagement in holding structure 252a, 252b.For example, and referring to figs. 17A through figure The the first holding structure 252a and the first locking structure 362a identified in 17C, But rotary joint 54 (for example, clockwise), so that The first end 420 of first locking structure 362a is close, and then enters at the arrival end 310 of the first holding structure 252a and catch Obtain region 314.Due to connector 54 tracing surface 364 and cover main body 70 guide surface 260 between (for example, such as Figure 17 D Between the sloped region 396 of first orbital segment 390a and the sloped region 268 of the first guide section 262a) sliding handover and it is right The helical rib answered, therefore when connector 54 rotates, connector 54 is vertically lowered or drops relative to holding structure 252a, 252b It is low, so that when arrival end 310 of the first locking structure 362a close to the first holding structure 252a, the first locking structure 262a's First end 420 is aligned with the capture region 314 at arrival end 310.For example, Figure 18 A to Figure 18 C shows connector 54 relative to capping The later phases of the rotation of main body 70.As shown in the cross section of Figure 18 C, the first end 420 of the first locking structure 362a has entered First keeps the capture region 314 of structure 252a.In this regard, as noted previously, as the first end of locking structure 362a The height of capture region 314 increases at 420 height reduction and arrival end 310, and locking structure 314 is easily directed to catch It obtains in region 426, wherein the interference between the upper surface of locking structure 362a 426 and the engagement surface 322 for keeping structure tab 302 It is minimum.

Lasting rotation (and/or vice versa) with connector 54 relative to capping main body 70, each locking structure 362a, 362b frictionally and will be mechanically locked at and keep structure 252a, in 252b in corresponding one capture region 314.Figure 19 A The lock state of reservoir 52 and connector 54 is shown to Figure 19 C.The tracing surface 364 (generality refers to) of connector 54 is relative to leading It is further rotated to surface 260 and along guide surface 260, to realize locking structure 362a, 362b is keeping structure 252a, More complete engagement in correspondence one in 252b.In addition, the undercutting 392a, 392b of connector 54 undercutting with capping main body 70 264a, 264b are engaged.For example, undercuting the fingers 400 of 392b against capping in connector second in the view of Figure 19 C Main body first, which is undercut, realizes adjacent handover between the shoulder 290 of 264a.The handover prevents connector 54 relative to capping 70 mistake of main body Degree rotation (and/or vice versa), and for being stably connected with component.

The section view of Figure 19 D, which illustrates, to be fixed in the capture region 314 (generality refers to) of the first holding structure 252a First locking structure 362a, and the shape and spatial orientation that reflect locking section 442 are along the wedging imitation capture region of section 330 314 shape and spatial orientation.In the locked state, the adjacent surface 424 of locking structure 362a is against capping main body guide surface 260 introduce region 266, and the locking section 442 of the upper surface of locking structure 362a 426 is against the engagement surface of tab 302 322 wedging part 330.Guide surface 260 and engagement surface 322 and adjacent surface 424 and above 426 are along wedging section 330 Downward angle relative to the plane perpendicular to rotation axis, which is orientated, to be determined, when locking structure 362a gradually advances through trapping region When domain 314 (that is, the first end 420 of locking structure 362a is gradually advanced from the arrival end 310 of holding structure 252a), 54 quilt of connector It pulls downward on or pulls in (orientation relative to Figure 19 D) to capping main body 70, thus the liquid-tight seal between promoting member.Example It such as, in some non-limiting embodiments, can be in the inner face 380 of ring packing rib 340 (Figure 14 B) and connector 54 of jet pipe 72 Foundation sealing is waited between (Figure 15 E), between jet pipe sealing surfaces 342 (Figure 14 B) and joint sealing surface 384 (Figure 15 E).Spray Seal of tube surface 342 and joint sealing surface 384 have the complementary configured for being designed to interfere and seal when system is locked. Capture region 314 easily allows first end 420 to pass through along the expanded height of gap section 332 to outlet end 312, in order to group Dress.
