Summary of the invention

The present invention relates to a kind of be used for receiving fluids container, special construction, prevent to palm off and the non-locking device that recharges type.

Can obtain the non-feature that recharges by following structure, this structure comprises packing ring/intermediate annular member, lower valve and last valve, the glass bead between two valves, pouring nozzle and maintenance sleeve.This structure allows liquid to flow facing one direction, but forbids that liquid flows in the opposite direction.When pouring out liquid by container inverted, valve from the valve seat position separately and when attempting in bottle re-filling liquid, because valve is seated on the valve seat that has liner, stops up and enters the inlet of bottle interior.

The invention is characterized in the non-structure that recharges, it comprises the lower valve of the annular element bottom that mediates, be positioned at lower valve in-to-in glass bead, and lower valve cooperatively interact and keep glass bead one between last valve and the lower valve be held the position on valve.The combination of these two valves can prevent very effectively that liquid from entering in the bottle, tilts so that pour out content and work as bottle, when valve and glass bead produce displacement, allows liquid to flow out.When position,, make lower valve be seated on the ring-shaped valve seats of intermediate annular member because glass bead is applied to the gravity on the lower valve along vertical direction.A series of little segmentation that vertically is provided with or rib on the bottom of intermediate annular member keep lower valve to be positioned at middle position, and forbid its displacement along vertical axis.Therefore, in order to pour out liquid from bottle, the center cavity on the lower surface of hydraulic shock lower valve makes lower valve produce displacement, and lower valve produces displacement thus, and, make that going up valve leaves its position, allows the flow of liquid mistake.

The non-structure that recharges has last valve, and it is positioned at the top of intermediate annular member, and its effect is to block by valve seat to enter the inlet of bottle interior.When container inverted was poured out liquid, because the glass bead bump is gone up the lower surface of valve internal, last valve separated with intermediate annular member.

A series of sagging teeth are arranged below the lower surface of last valve, and the upwardly extending tooth that itself and another group is positioned on the lower valve cooperatively interacts, and its objective is, rotates if go up valve, and then lower valve rotates thereupon.This reason is because threaded cap when outwarding winding, the valve seat of valve, lower valve and intermediate annular member being gone up in influence and going up lower valve contacting each other, and valve can rotate.Adhesion between the valve seat will stop and produce displacement between the valve, particularly comprise sugar when liquid, and perhaps during some other materials, these materials are tending towards being bonded in valve base surface.

The non-locking device that recharges has two latch surface, when passing through the screw thread installing and locating with convenient closure member on container, avoids liquid outwards to flow.One of them latch surface constitutes by one or more sagging concentric annular elements, and it enters the upper chamber of pouring nozzle, so that stop up outlet.Another latch surface is made of the center rod member of the roof inside face of the inner cap of closure member.Enter the installation site by the spiral locking device, rod member is entered in the pouring nozzle by center cavity, the lower end of rod member becomes the cross-piece structure, and it enters in the cone-shaped cavity of valve.Rod member promotes to go up valve and is close to intermediate annular member and valve seat, therefore stops up liquid and flows out by the outlet of intermediate annular member.Another purpose of this rod member is, when closure member is outwarded winding, makes valve rotate, and this is because cross-piece enters the cone-shaped cavity of valve, makes valve along with threaded cap rotates.

Threaded cap or closure member have antitheft demonstration band or the annular element that is positioned at its downwardly depending wall below, outside, it has a series of teeth with angle that extend internally, the effect of these teeth is to allow under the condition of not destroying top cover, top cover is installed, meanwhile, after top cover is twisted away, forbid that annular element rotates.This be since the tooth that is provided be positioned at intermediate annular member below on the outer surface a series of teeth that have angle be abutted against mutually and touch.Described annular element is connected on the locking device body by a series of horizontal components or bridgeware, and described bridgeware can destroy the globality of annular element and outer cover, and when enclosing cover is outwarded winding, when annular element did not rotate, annular element was removed.This antithief display ring can be provided with two vertical incisions, and it is at a distance of 180 °, when annular element when the locking device body separates, described annular element is destroyed, and is divided into two parts.

At the top of enclosing cover is the outside with closure member of screw thread, and it is by the fixing position of inner cap of the horizontal rib of enclosing cover inboard.Horizontal rib interlocking on the outside of these ribs and inner cap.The project organization of inner cap has circle, has the surface of groove, its with outer interior surface on the surface that has groove cooperatively interact.

Owing to require closure member or top always to be screwed to the tram, so at the upper surface setting of pouring nozzle two ridges at a distance of 180 °, it matches with two similar indentations above being positioned at top inner surface with respect to pouring nozzle.Consequently ridge makes the tooth of antithief display ring be in the tram, when being screwed into for the first time with convenient top, its between the tooth of pouring nozzle, thereby when for the first time turning on the screw thread fit closure top, cause that the horizontal component or the bridgeware that connect antithief display ring and top body rupture.

Keep sleeve to constitute the outside cylinder part of the below of locking device, by buckle, bonding or will keep sleeve to be installed in the bottom of pouring nozzle by ultrasonic welding.

Have a series of angled horizontal rib or fixture at the interior cylindrical surface that keeps sleeve, it allows sleeve to slide at neck part, and be positioned the below of the outward extending circular band of neck part, therefore attempt can avoid it to take off or moving sleeve when bottle takes off sleeve as the people.On the interior cylindrical surface of sleeve, also be provided with a series of ribs that vertically are provided with, the groove that these ribs are arranged in the grooving on the bottle neck or vertically are provided with, they are in contact with one another cooperation, prevent that sleeve from rotating.

, may go wrong a little bevelled the time at container " I ", that is, lower valve " G " may break away from intermediate annular member " D ", and can recharge content in bottle " I ".In order to prevent this problem, as shown in figure 10, wherein described another project organization of lower valve 121.Intermediate annular member 120 has ring-shaped valve seats 125, and said ring-shaped valve seats 125 is meshing with each other with the ring-shaped valve seats 126 of lower valve.As first embodiment, when lower valve and intermediate annular member were alignd mutually, as shown in Figure 1, fluid impassabitity lower valve flowed in the container, because unique passage is by adjacent valve seat.Pressure from the analogue in the inside 127 of glass bead or lower valve 121 forces valve seat mutually near forming the tight seal structure thus.In addition, when container turned upside down or tilt, lower valve 121 moved up, and allowed flow of liquid by hole 128.In this embodiment, lower valve has the straight rod member 122 that extends from its lower surface downwards.Described straight rod member 122 extends through the bottom of intermediate annular member 120 downwards, and passes hole 124, and described hole 124 is arranged in the diapire 123 of intermediate annular member 120.Central authorities' rod member 122 guarantees that lower valves 121 are positioned at suitable settling position, and is positioned at the middle position of valve seat 125, and therefore, when bottle or non-when recharging closure elements inclination certain angle, valve 121 can not produce displacement.

For the user of package determines the displacement vertically of suitable work capacity and valve, in Figure 11, described a kind of additional embodiment, wherein go up valve 131 and extend upward, pass the hole 132 in the pouring nozzle 135.Valve rod 130 extends upward, and its extended distance is greater than the structure shown in fwd Fig. 6 a.Described valve rod 130 has the hole 134 that is positioned at top portion, so that hold the rod member 133 that extends from the inner top wall of screw thread closing cap downwards.When bottle is tilted, so that fluid is by valve, and when flowing out by flow orifice 136, last valve vertically moves, so that pouring nozzle 135 is passed at valve rod 130 places of extending upward, for the user provides the cue mark that can see, this moment, valve 131 was working properly.

In the project organization of another kind through modification, in order to prevent the content in the package by shaking locking device, content is entered in another package,, can satisfy above-mentioned requirements by adopting the lower valve with single annular lip 142 143 as shown in figure 12.In this project organization, lower valve 143 contacts are positioned at the annular lip 142 on the intermediate annular member 145.Described lower valve 143 has the part 140 of downward extension, the part 140 of described downward extension has and is positioned at the sidewall of below, has outward extending protrusion 144 on sidewall, and described sidewall is an enclosed construction, but, do not contact the wall 146 that intermediate annular member is extended downwards.Therefore, between lower valve 143 and intermediate annular member 141, only there is the unique contact point in flange 142 places, allows moving of lower valve not interrupted.And lower valve 143 has flexibility, so that provide enough sealings around beading or flange 142.And, can overcome because not round-formed shape of a saddle flange 142 structures of container hole.Horizontal throw between circular wall 146 and protrusion 144 can be very little, therefore between these two surfaces, under the condition that obvious contact point is not provided, can form leak free state a little.Also have, protrusion 144 can leave the another kind of state shown in the right side among Figure 12 along the downward wall 146 that extends on the intermediate annular member.Annular wall 141a below being positioned at shown in the accompanying drawing 12 and the distance that is similar between the annular surface 140a of below of valve 140 (in the left side) constitute boiler check valve, so that can be by before the valve at a large amount of contents, valve must vertically mobile preset distance.Therefore height according to sidewall 147 can change this distance, and before liquid flows out, lower valve is with respect to intermediate annular member 141, the predetermined distance of vertically lifting off a seat, and this predetermined distance is provided by the length of sidewall 147.This predetermined distance can make to greatest extent that to recharge closure elements effective, and prevents from by rocking or other devices container to be recharged.

A kind of improved boiler check valve can be arranged on the lower valve, thereby guarantees to form between lower valve and intermediate annular member sealing fully.Shown in Figure 13 a and 13b, on intermediate annular member 151, be provided with annular block piece 152, it is used in combination with the flexible sealing tabs 153 that approaches.Sealing tabs 153 provides first hermetically-sealed construction between intermediate annular member 151 and valve 150.As second hermetically-sealed construction, block piece 152 can be positioned on the intermediate annular member, and extends upward thus, is in contact with one another with the following annular surface 155 of valve 150.In addition, the block piece 154 that extends can be arranged on the outward flange of annular valve 150 downwards, shown in Figure 13 b.At assembly process, if pressure forces liquid to pass through boiler check valve, the compression of block piece on the intermediate annular member 151 or the restriction of the block piece on valve 150 sealing tabs 153 perhaps helps the sealing that keeps suitable.

Non-ly recharge another problem that closure member need consider and fully be tightened onto on the pouring nozzle for this, rotate when stopping, particularly when needs are considered independent element machining tolerance, need install suitable sealing this when bottle cap.Adopt embodiment shown in Figure 14, can eliminate potential leakage hidden danger.

As shown in figure 14, non-ly recharge the bending features that closure member has permission, the roof of flexible inner cap 160 has above-mentioned bending features, and above-mentioned roof is K/UP a little, so that exert pressure to outstanding last valve 162 by rod member 161.Valve 162 has flexible annular surface 163a on this, shown in left side among Figure 14, and residing state before its expression threaded cap is exerted pressure downwards.Therefore the upwardly extending wall 164a contact of intermediate annular member annular surface 163a, when threaded together lid 160 moves down, causes the annular surface K/UP.Annular surface 163b in the right side of Figure 14 part represents that it is after fully threaded together is covered, with the mutual pressure fitted of wall 164b of the intermediate annular member of being out of shape a little.Sidewall 164b by surperficial 163a and intermediate annular member or 160 distortion of the roof of lid, valve 162 bendings in permissions, although in the manufacturing course of processing small tolerance, still can guarantee to provide sufficient sealing.

In order to provide additional or another kind of antitheft indicating device, sealing arrangement 170 is leaned on mutually with the lip 172 of pouring out of pouring nozzle 174 to the non-closure member that recharges.Described inner sealing device 170 has pulling-on piece 171, and in order to remove circular seal dish or packing ring 170, the user can peel off this pulling-on piece 171.In addition, described pulling-on piece 171 can be provided with the hole 173 that is positioned at middle position, and the rod member of the threaded cap of extension enters valve 176 so that allow downwards, and exerts pressure on last valve 176, described in fwd embodiment.Inner sealing device 170 is poured out lip 172 contact pouring nozzles 174 along annular, and is thereon bonding by induction bonding or similar means.Therefore, when using for the first time,, before distributing content, must remove inner sealing device 170 on the lip 174 pouring out in order to indicate the anti-joyride device that has in the inside of container formerly.As shown in figure 16, in order between pouring nozzle 181 and threaded cap 180, to provide sufficient sealing, be provided with flexible flange 182 at the upper surface of pouring nozzle 181, so that between threaded cap inner top wall 183 and pouring nozzle 181, form suitable hermetically-sealed construction.Described flange 182 provides sufficient sealing between pouring nozzle and closure member, therefore the hermetically-sealed construction of this easy bending can guarantee there is not unrestrained content between closure member 180 and pouring nozzle 181, and content can not enter threaded portion therebetween yet.Liquid contents in this threaded portion finally distributes along the outside of container, and this is the situation of least wishing.Flange 182 can be molded in upwardly extending position, and in the assembling course of processing, by the assembling axle, perhaps by closure member is screwed on the pouring nozzle, can make flange 182 bendings, as shown in figure 16.The application force that screw thread moves is arranged on the pouring nozzle closure member, applies sufficient pressure thus, makes flange 182 bendings, and, between the inner bottom surface 183 of pouring nozzle 181 and threaded cap 180, constitute sealing fully.After the enclosing cover of outwarding winding, flange 182 returns its upwardly extending angle position, constitutes thus and pours out lip.

In non-another problem that exists in the antitheft indicating device of closure member that recharges is under the heating environment condition, can remove the non-valve that recharges.Because keep sleeve, perhaps valve self is made by thermoplastic resin material, is enough to make it to be easy to generate distortion by heating, so that take out these elements from container neck.Under normal environmental conditions, when container neck takes off sleeve, cause the maintenance sleeve fragmentation of making by thermoplastic resin material, indicate container stolen thus.But, under the condition of heating material, for the user, take out valve from container without any antitheft indication.Another structure that prevents this phenomenon is to keep on the sleeve 190, perhaps indicate printing ink or other chemical substances in its outer setting heat, therefore, if keep sleeve to be placed under the heating environment condition, can see suitable warning or other cue marks 191, as shown in figure 17.Therefore, if container neck is heated to predetermined temperature,, can observe antitheft indication by " personation " mode or other the colored mandatory signs that adopts temperature sensitive ink to write.This will warn the user, and closure member is stolen before this, and its content does not guarantee.

Another kind prevents container heating and to remove the non-means that recharge closure member from container be that horizontal surface 53 along the intermediate annular member " D " shown in Fig. 5 a applies the thermal resistance adhesives.Such adhesives can prevent to remove intermediate annular member by the non-closure member that recharges is immersed in the hot water from bottle.After applying this adhesives, remove intermediate annular member, will cause intermediate annular member the damage that can see to occur, provide antitheft indication for content thus.

18 go through a kind of unlatching barrier structure with reference to the accompanying drawings, wherein container 200 is provided with block piece 203, and described block piece 203 control ratchets 205 are with respect to the position between the ratchet 202 of container neck.Can see that from accompanying drawing 18 block piece 206 is set directly at closure member 201 bottom margins, its direct contact block piece 203, therefore block piece 203 does not hinder the closure member rotation and opens, but, when block piece 203 and 206 is in contact with one another, prevent that closure member 201 from continuing to rotate with the sun.The correct position of ratchet 205 and 207 between the ratchet on the container neck 202.Ratchet 205 is positioned on the inside face of antitheft index strip 207, and for the first time from container 200 dismounting closure members 201 time, antitheft index strip 207 breaks.In the process that closure member is installed, because block piece 203 and 206 prevents that closure member 201 is rotated further on container threads 204, hermetically-sealed construction is provided, as Figure 19 and shown in Figure 14, it is sagging that feature 160a is positioned at the roof below of closure member 201, and fill in the inside of the neck and the pouring nozzle 39a of container 200.This plug formula sealing will be worked in the altitude range of blocking junction member, so that guarantee that closure member after can not being rotated further, can prevent that equally the content in the container from outwards scattering.

Accompanying drawing 19 depicted in greater detail the hermetically-sealed construction that combines of pouring nozzle and bottle cap, open barrier structure, in accompanying drawing 19a, the stopper seal of describing 211 is sagging from the roof downside of closure member 210, and is pressed against on the sidewall of the pouring nozzle that combines with bottle cap.Described the another kind of form of this sealing member in Figure 19 b and 19c, the beading 212 that wherein extends internally contacts with the sidewall outside face topmost of container pouring nozzle and bottle cap integrated structure.In Figure 19 c, outward extending beading 213 contact closure member sidewalls inside face topmost.These different embodiment can guarantee to constitute sufficient hermetically-sealed construction between closure member and container or pouring nozzle, and by opening barrier element, can both guarantee effectively along any possible version of whole length range in the vertical direction.

In accompanying drawing 19d, 19e, 19f, 19g, described other and opened the version of barrier structure.In accompanying drawing 19d depicted in greater detail in the outside of container neck, perhaps in the non-details that recharges the projection 214 that is provided with on the pouring nozzle assembly below the lower edge of closure member 210.The sagging projection 215 that is mated is arranged on the lower edge of closure member 210, so that contacting container or the non-unlatching that recharges on the pouring nozzle assembly stop projection, thereby prevents that closure member 210 is rotated further.In addition, in accompanying drawing 19e, projection 217 or 216 can be arranged on the inner wall edge of assembly or closure member.The rib that vertically is provided with that is positioned at closure member 210 bottoms contact similar projection and the block piece 217 on the bottom that is arranged on container neck with projection 216, thereby prevents closure member rotation along clockwise direction on container.In accompanying drawing 19f, similarly projection or block piece 219 are set at closure member in-to-in upper limb, and its position is positioned at the top of screw thread, and the element of label 15 expressions has also been described this structure in accompanying drawing 3.These are contact block piece 218 similarly, and perhaps the element shown in Fig. 4 37 is positioned near the mouth of container or pouring nozzle assembly, in case the mutual adjacent contact of these block pieces, it prevents that closure member from rotating on container.At last, accompanying drawing 19g depicted in greater detail in the inside of closure member screw thread 222 is set, wherein screw thread 222 has blunt end portion 221.The closure member perfect thread is tightened on the container, and described blunt end portion 221 docks with barrier element 220, and described barrier element 220 is positioned at the below of the matching thread of container neck or pouring nozzle assembly.Cooperation projection or retaining means on container or closure member can have the angle of turning back, so that directly do not form 90 ° of angles, that is, with respect to the inwall that connects projection, these projections or block piece angle separately is less than 90 °.This structure causes cooperating projection to be pulled in together, because the angle of mutually opposed block piece, they clamp mutually, and the control barrier effect is arranged.It is excessive that all these embodiment can prevent effectively that the tooth of container and pouring nozzle assembly or closure member or ratchet from rotating, perhaps dislocation.

At last, with reference to accompanying drawing 20, inner cap 231 and enclosing cover 230 can be assembled in second step of separating, so that comprising the inner cap of antitheft indicating ring 232 can be mounted, and can not occur foregoing owing to cover in enclosing cover is installed in advance, and the destroyed this phenomenon of antitheft indication spoke sheet that produces.At first make inner cap 231, and it is installed on the container, so that antitheft index strip 232 is stayed the top of continuous beading 237.Before enclosing cover is installed, improved inner cap is installed on pouring nozzle or the neck, when screwing inner cap 231, eliminate any disturbing factor between the ratchet of the antitheft index strip that cooperates.As described above, after screwing inner cap 231, enclosing cover 230 is snapped onto on the inner cap 231, force the antitheft index strip of inner cap to move down, and cross over beading 237, perhaps cross ratchet.Outer rib 233 and 234 engages with the beading 235 and 236 that extends internally, and makes enclosing cover cover in remaining on.This project organization allows inner cap is connected in the easier fragmentation of spoke sheet of antitheft index strip, and this is needs noted earlier, because this structure prevents the spoke sheet because the inner cap spiral is screwed on the container, and destroyed in advance.Ratchet must stop or the pivoting friction of antitheft index strip beading by the retainer belt of vessel port and pouring nozzle mutually.
