Description

The hermetically-sealed construction of vessel port

Technical field:

The present invention relates to a kind of hermetically-sealed construction of vessel port, particularly a pressure part utilizes a compression leg and at least one pushing portion axially to push an elastic body downwards, so that this elastic body axial compression and radial dilatation, and then the seal of vessel structure of increase sealing effectiveness.

Background technology:

The market sale for convenience of beverages such as general spirits and grape grape drinks, usually with the bottle of glass or ceramic as container.In the bottling process, drinks is distilled into hot wine earlier, then injects a bottle with pressure condition in high; Traditionally, the compressing of one bottle stopper can be filled in the bottleneck of the bottle of filling wine during bottling, to seal its bottleneck.At this moment, fill the barometric pressure of pressing in the bottle of wine in fact greater than external environment.In addition, structurally, the external diameter of this bottle stopper must be designed to be slightly larger than the internal diameter of bottleneck at least.Whereby, after this bottle stopper axially inserts this bottleneck, just can guarantee the mutual driving fit of inwall of the outer wall and the bottleneck of this bottle stopper, and this bottle stopper be resisted press in high in this bottle and can not be deviate from,, not allow drinks acid bad or influence its content so that preserve drinks for a long time.Yet, in the process of bottling, insert bottle stopper in the bottleneck and be not easy, particularly contain in the bottle in push outward high and press, this causes bottle stopper not remain in the bottleneck firm always location.

Traditionally, bottle stopper is made by the cork with pore.When the envelope bottle, even the interior pressure of bottle is too high, the cork of bottle stopper itself also can pass through the suitable hold-off pressure of pore, and therefore the bottle stopper of being made by cork can be considered the structure-improved of a kind of bottle stopper and bottleneck closed intensity.Yet in order to make bottle stopper and bottleneck tight joint, the external diameter design of bottle stopper is greater than the interior neck of bottleneck, but this causes bottle stopper to be difficult to inject in the bottleneck in the bottling process.In addition, the cracked easily or fracture of moist and shabby cork is so that be difficult to cork by taking out in the bottleneck.

Another bottle stopper structure commonly used, as the U.S. the 6th, 536, No. 618 " bottle stopper (Bottle Plug) ", Japanese 2003-522080 number " expanding bottle stopper (Expansion Bottle Plug) " and No. 02/36450 patents of invention such as " expanding bottle stopper (Expansion Bottle Plug) " of PCT, it discloses a bottle stopper and has comprised a body, a compression leg and an elastic body, and this body has a depressed part and several enlarged portion.This compression leg has an inserted link, can axially insert downwards in the depressed part of this body, and force this enlarged portion radially outward to be expanded.This elastic body has a depressed part, and it is used for holding at least the enlarged portion of this body.Be used for when bottle envelope at this bottle stopper, at first axially press down this compression leg, force the enlarged portion of this body radially outward to be expanded with the axial pressing action of the inserted link that utilizes this compression leg.Then, related this elastomeric perisporium that forces of the enlarged portion of this body is radially outward expanded, and closely is connected to a bottle, thereby finishes the action of envelope bottle.In addition, this elastic body is made by elastic body materials such as (elastomer), is used for replacing cork, the shortcoming that the cork normal off splits when avoiding uncork.

But, in envelope bottle process, still there is following other problem in above-mentioned bottle stopper on reality is used, for example: though the axial pressing action of the enlarged portion of inserted link that above-mentioned bottle stopper can be by this compression leg and body causes this elastomeric perisporium radial dilatation, this inserted link and enlarged portion in fact only can cause this elastic body to form limited radial dilatation degree (1).Therefore, under radial dilatation degree condition of limited, the bottle stopper of single specification only can be applicable to the bottle that bottleneck bore specification is extremely approximate, so that limit the Applicable scope of the bottle stopper that has dwindled single specification relatively.In other words, maker can only make the bottle stopper of all size by continuous die sinking, just can be applicable to the bottle of various bore specifications.Like this, not only reduce the Applicable scope of bottle stopper relatively, and also can cause increasing die sinking and production cost.(2), in addition, at present commercially available bottle mostly is glass material greatly and makes by the blowing mode.But the bottle of blowing inevitably forms the micro-pits portion at least one place usually at the bottleneck inwall, so that the actual bore value of bottleneck inwall is greater than default bore value.Therefore, under the limited prerequisite of the radial dilatation nargin of above-mentioned bottle stopper, even maker according to the bottle stopper of the customized corresponding specification of default bore specification of bottleneck, the untrue situation of envelope bottle still may take place in it, thereby increases the return of goods rate of bottle stopper on foot.

The bottle stopper structure commonly used that other is relevant, also can be with reference to the U.S. the 2nd, 021, No. 259 " bottle sealing member (Bottle Closure) ", the 2nd, 718, No. 974 " expanding bottle stopper (Expansion Stopper) ", the 3rd, 430, No. 777 " the tool total head is made the thief-proof bottle cap (Pilferproof Cap with IntergralPressure Actuated Sealing Means) of dynamic sealing device ", the 3rd, 638, No. 821 " Bottle ﹠ Can; the hermetically-sealed construction of container (Closure for Bottles and Similar Containers) ", the 3rd, 926, No. 329 " Plastic bottle plug of the bubble drinks bottle of tool enlarged portion (Stopper of Plastics Having an Expansible Portion forBottles for Sparkling Wines and the Like) ", the 4th, 902, No. 270 " centrifugal body (Centrifuge Tube) ", the 5th, 722, No. 548 " Cork as a stopper of wine bottle (Cork Stopper for Bottles ofWine) ", the 5th, 732, No. 837 " can reduce the pressure release glass bottle hermetically-sealed construction (Vented Vial Closure Member for Freeze-Drying which MimimizesContamination of Freeze-Dried Products) that the lyophilisation inclusion is polluted ", disclose No. 2004/0112856 " bottle stopper (Bottle Stopper) ", Britain the 2nd, 190, No. 072 " sealing arrangement of champagne bottle (Closing Devicefor Bottles of Champagne and the Like) ", France the 2nd, 572, No. 719 " can repeat to seal the bottle stopper of use; the bottle stopper of carbonated beverage bottle (Resealing Stopper; Particularly forGassy Beverages) particularly ", No. 2004/522660 " bottle stopper (Bottle Stopper) " of Japan, European Union No. 1377506 " bottle stopper (Bottle Stopper) " and No. 02/083515 patents such as " bottle stopper (BottleStopper) " of PCT, it roughly all comprises similar assemblies such as a compression leg and an elastic body, and be by axially pressing down the action of this compression leg, and the inserted link bottom of causing this compression leg radially outward pushes this elastomeric perisporium, this elastomeric perisporium is radially outward expanded, to seal the bottleneck of a bottle.But under this elastomeric axial length unmodified situation, in fact this compression leg can only cause this elastic body to produce limited radial dilatation degree.Therefore, above-mentioned patent has previous described shortcoming equally, for example: reduce bottle stopper Applicable scope relatively, and cause increasing die sinking and production cost, and the untrue situation of envelope bottle may take place, thereby increase the return of goods rate of bottle stopper on foot.

Another bottle stopper structure commonly used, as No. 327412 " structural improvement of bottle stopper " the novel patent in Taiwan, it discloses a bottle stopper and has comprised a body of rod, and upwards wears an elastic body, a block, a packing ring and a bottle cap successively by this body of rod, and the outside face in this bottle cap articulates a pull piece at last.By axially pulling this pull piece downwards,, make the bottom of this body of rod axially upwards oppress this elastic body and radially outward expand axially upwards to spur the bottom of this body of rod.Whereby, under the situation that this elastomeric axial length is compressed, this elastic body will produce bigger radial dilatation degree, to increase the fiduciary level of envelope bottle.Yet the envelope bottle action of above-mentioned bottle stopper realizes by axially pulling this pull piece downwards, but commercially available business-like full automaticity bottle capper can only carry out axial pressing action usually.Simultaneously, this pull piece is set on this bottle cap, also makes this bottle cap can't be additionally in conjunction with the required decorative cover of various bottles.So even this bottle stopper has preferable envelope bottle effect, but the restriction that the pull piece of this bottle stopper causes volume production envelope bottle and uses is unfortunate very.

Another bottle stopper structure commonly used, as No. 409703 " adjustable bottle stopper device " the novel patent in Taiwan, it discloses a bottle stopper and has from top to bottom comprised a knob, an elastic body and an adjusting lever successively.The bottom of this knob has the groove that is spirally connected, and the top of this adjusting lever has an outside thread.When this bottle stopper places the bottle mouth position of a bottle, by rotating this knob, this adjusting lever is axially moved up, then the bottom of this adjusting lever is axially upwards oppressed this elastic body and is radially outward expanded.Whereby, under the situation that this elastomeric axial length is compressed, this elastic body also can produce bigger radial dilatation degree, to increase the fiduciary level of envelope bottle.Yet the envelope bottle action of above-mentioned bottle stopper realizes by rotating this knob, but commercially available business-like full automaticity bottle capper can only carry out axial pressing action usually.In addition, in rotation during this knob, because the bottom of this adjusting lever is not resisted against the inwall of this bottleneck really, so this knob and adjusting lever form idle running in fact easily, so that seal and bottle fall flat.In addition, this bottle stopper lacks the clip location structure, can't guarantee that this bottle stopper maintains suitable spiral lockup state.Simultaneously,, then may cause this elastic body excessively to oppress the bottleneck of this bottle, thereby cause breaking of this bottleneck, and then the incised wound user be arranged or reduce the anxiety of sealing the bottle yield if user or full automaticity bottle capper platform excessively rotate this knob.

For these reasons, all there are some shortcomings of using in above-mentioned various bottle stoppers commonly used, therefore still are necessary further to improve the hermetically-sealed construction of said vesse opening really.

Summary of the invention:

Main purpose of the present invention is to overcome the above-mentioned defective that exists in the prior art, a kind of hermetically-sealed construction of vessel port is provided, wherein a pressure part utilizes a compression leg axially to push an elastic body downwards, make this elastic body axial compression and radial dilatation, to increase elastomeric radial dilatation degree, make the present invention have the effect that improves sealing effectiveness.

Secondary objective of the present invention provides a kind of hermetically-sealed construction of vessel port, wherein a pressure part utilizes a compression leg and at least one pushing portion axially to push an elastic body downwards, make this elastic body axial compression and radial dilatation, to increase elastomeric radial dilatation degree, make the present invention have the effect that improves sealing effectiveness.

Another purpose of the present invention provides a kind of hermetically-sealed construction of vessel port, wherein a pressure part utilizes a compression leg axially to push an elastic body downwards, make this elastic body axial compression and radial dilatation, and this pressure part utilizes the corresponding clip at least one location division at least one lock part of a pedestal, to guarantee to keep the state of this elastomeric axial compression and radial dilatation, to make the present invention have the effect of guaranteeing airtight quality.

According to the hermetically-sealed construction of vessel port of the present invention, it comprises a pressure part, a pedestal and an elastic body.This pressure part is provided with a compression leg and at least one location division.This pedestal is provided with a top support lugn, a central siphon, an end support lugn and at least one lock part.This elastic body can be sheathed on outside the central siphon of this pedestal, and between this top support lugn and end support lugn.The compression leg of this pressure part produces axial compression and radial dilatation to cause this elastic body, thereby seals a container in order to axially to push this elastic body downwards.Simultaneously, the location division of this pressure part is used for the lock part of corresponding this pedestal of clip, to guarantee to keep the state of this elastomeric axial compression and radial dilatation.

As mentioned above, the hermetically-sealed construction of vessel port commonly used causes this elastomeric perisporium radially outward to expand, to seal the bottleneck of a bottle just by axially pressing down the action of this compression leg.But, under this elastomeric axial length unmodified situation, this compression leg in fact only can cause this elastic body to produce limited radial dilatation degree, the hermetically-sealed construction of vessel port of the present invention by the compression leg of pressure part in order to axially to push this elastic body downwards, causing this elastic body to produce axial compression and radial dilatation, thereby seal a container.Simultaneously, the location division of this pressure part is used for the lock part of corresponding this pedestal of clip, to guarantee to keep the state of this elastomeric axial compression and radial dilatation.

Therefore, compare with the hermetically-sealed construction of vessel port commonly used, the hermetically-sealed construction of vessel port of the present invention can increase this elastomeric radial dilatation degree really relatively, and then improves sealing effectiveness, guarantees airtight quality, increases Applicable scope and reduces the die sinking cost.

As Fig. 1, Fig. 2 and shown in Figure 3, the pressure part 10 of first embodiment of the invention comprises compression leg 11 and at least two pushing portions 12.This compression leg 11 and pushing portion 12 are utilized by inertia materials such as plastics that injection molding method is prefabricated respectively to form.This compression leg 11 is essentially down bowl-type, and it is provided with an axial inner face 110, an inserted link 111, at least one card base 112 and at least one hook portion 113.This axial inner face 110 is positioned at the side of this compression leg 11 near this pushing portion 12.This inserted link 111 is axially to be extended downwards by the midway location of this axial inner face 110 to form, and this card base 112 is that the axial end portion by this inserted link 111 axially extends to form downwards, and this card base 112 forms equidistant symmetric offset spread mutually.113 side faces by this card base 112 of this hook portion extend radially outwardly and form.The upper axial end of this hook portion 113 forms a clamping face a, and its relative essence is perpendicular to the outer peripheral face of this card base 112, and the lower axial end of this hook portion 113 forms one and separates door bolt face b, and its relative actual tilt is in the outer peripheral face of this card base 112.This card base 112 and hook portion 113 are the location division of this compression leg 11, and it is used for carrying out the elasticity location.

In addition, as Fig. 1, Fig. 2 and shown in Figure 3, the cell cube of this pushing portion 12 is respectively equipped with at least one axial bottom surface 120, at least one extending pin 121 and at least two lands 122,123.This axial bottom surface 120 is positioned at the side of this pushing portion 12 near this elastic body 30, and this extending pin 121 is convexly set in the side of this pushing portion 12 near this compression leg 11, and this extending pin 121 is essentially arc sheet.This land the 122, the 123rd is selected from cooresponding snapping head and snap groove, or the analog structure of other corresponding combination.This land 122,123 is used at least two cell cubes of this pushing portion 12 are combined into one, and forms an axis hole 124 jointly.

As Fig. 1, Fig. 2 and shown in Figure 3, the pedestal 20 of first embodiment of the invention is utilized by inertia materials such as plastics that injection molding method is prefabricated to form.In the axial direction, this pedestal 20 from top to bottom is provided with a top support lugn 21, a central siphon 22 and an end support lugn 23 successively.The outside dimension of this top support lugn 21 is at least greater than the bore (as Fig. 4) of this bottle 40, can avoid like this that this pedestal 20 is whole in use to be absorbed in this bottle 40.This top support lugn 21 forms an axis hole 210 and several annular distances 211 in addition.This axis hole 210 is positioned at the midway location of this top support lugn 21, and this axis hole 210 at least axially is arranged with the inside that extends to this central siphon 22 downwards, makes this central siphon 22 form hollows, and the bottom of this axis hole 210 is then sealed by this end support lugn 23 simultaneously.211 of this annular distances equidistantly be located on this axis hole 210 around, and the shape of this annular distance 211 is corresponding to the extending pin 121 of this pushing portion 12, promptly this annular distance 211 is essentially arc.

In addition, as Fig. 1, Fig. 2 and shown in Figure 3, the outer peripheral face of this central siphon 22 is used for sheathed these at least two pushing portions 12 and elastic body 30, and its inside is hollow and is communicated to this axis hole 210.The inner peripheral surface of this central siphon 22 is arranged with at least one door bolt portion 221, at least one lock part 222 and at least one guide groove 223 separated, for the hook portion 113 selectivity clips of this compression leg 11.This central siphon 22 axially on, this axial location of separating door bolt portion 221 is relatively higher than the axial location of this lock part 222, and this separates door bolt portion 221 and lock part 222 is preferably through hole, it can be communicated with the inside and outside side face of this central siphon 22.This separates door bolt portion 221 and lock part 222 to this guide groove 223 in order to axial connection, and the degree of depth that radially is arranged with of this guide groove 223 radially is arranged with the degree of depth less than what this separated door bolt portion 221 and lock part 222.

In addition, as Fig. 1, Fig. 2 and shown in Figure 3, this end support lugn 23 is a plectane body, and its outside dimension is at least less than the bore (Fig. 4) of this bottle 40, so that this central siphon 22 and end support lugn 23 essence embed in this bottle 40.When central siphon 22 sheathed these at least two pushing portions 12 of this pedestal 20 and elastic body 30, this end support lugn 23 also can support this pushing portion 12 and elastic body 30, to prevent these at least two pushing portions 12 and elastic body 30 these pedestals 20 of disengaging and to fall in this bottle 40.

As Fig. 1, Fig. 2 and shown in Figure 3, the elastic body 30 of first embodiment of the invention is made by elastic material, for example thermoplastic elastomer (thermoplastic elastomer), rubber (rubber), polyurethane (PU), polyolefin (polyolefin) and other macromolecular material etc.The outside dimension essence of this elastic body 30 approaches the bore (Fig. 4) of this bottle 40, but these elastic body 30 essence embed in this bottle 40 like this.In addition, this elastic body 30 is provided with an axis hole 31, one an axial end face 32 and an axial bottom surface 33.When preliminary assembling, the elasticity that this elastic body 30 can utilization itself is crossed the end support lugn 23 of this pedestal 20, and utilizes this axis hole 31 to be sheathed on outside the central siphon 22 of this pedestal 20.This axial end face 32 is positioned at the side of this elastic body 30 near this pushing portion 12.This axial bottom surface 33 is positioned at the side of this elastic body 30 near the end support lugn 23 of this pedestal 20.

As shown in Figure 3, when finishing assembling, the compression leg 11 of this pressure part 10 and pushing portion 12 and pedestal 20 and elastic body 30 common formation one hermetically-sealed constructions.Before the sealing structure was not used to seal this bottle 40 as yet, this compression leg 11, pushing portion 12 and elastic body 30 are in separated latch mode.At this moment, in the axis hole 210 of the top support lugn 21 of inserted link 111 these pedestals 20 of insertion of this compression leg 11.The hook portion 113 temporary transient clips of this inserted link 111 are in the door bolt portion 221 that separates of this central siphon 22, and the clamping face a clip of this hook portion 113 this separate the hole wall of door bolt portion 221, axially move up to prevent this hook portion 113, and then avoid this compression leg 11 axially upwards to break away from this pedestal 20.Axial bottom surface 120 easy fits of this pushing portion 12 amplexiform axial end face 32 in this elastic body 30.The extending pin 121 of this pushing portion 12 passes the annular distance 211 of this top support lugn 21, and faces the axial inner face 110 of this compression leg 11.33 supports that are subjected to this end support lugn 23 in the axial bottom surface of this elastic body 30.

As Fig. 3, Fig. 4 and shown in Figure 5, when the sealing structure is used to seal this bottle 40, one user or a full automaticity bottle capper (not illustrating) apply an axial suppressing action power to this compression leg 11, this compression leg 11 is axially moved down, and the axial inner face 110 of this compression leg 11 push the extending pin 121 of this pushing portion 12.At this moment, this pushing portion 12 axially moves down, and therefore this axial bottom surface 120 will be tight against the axial end face 32 of this elastic body 30.Because the axial bottom surface 33 of this elastic body 30 is subjected to the support of this end support lugn 23, making this axial bottom surface 33 to produce moves axially, therefore cause this elastic body 30 to be forced to form axial compression, and its outer peripheral face produce expansion radially outward by this axial end face 32.Because axial compression take place in this elastic body 30, reduce axial overall length, therefore can increase considerably the radial dilatation nargin of this elastic body 30, so help improving sealing fiduciary level between the bottleneck inwall of sealing structure and this bottle 40.It should be noted that because the present invention is an axial pressing action by this compression leg 11 to seal this bottle 40 that the therefore axially press seal bottle mode down of the full automaticity bottle capper that is particularly suitable for using always is so be applicable to the process of volume production envelope bottle.In addition, according to product demand (for example bottle), the axial end face of this compression leg 11 (not indicating) also can be used in conjunction with a decorative cover (not illustrating), and the present invention can further increase the visual effect and the value added of product whereby.

Then, as Fig. 4 and shown in Figure 5, by when separating latch mode and change over lockup state, the hook portion 113 of the inserted link 111 of this compression leg 11 utilizes this dip plane b to break away from the door bolt portion 221 that separates of this central siphon 22 easily, and axially move down along this guide groove 223, until clip till this lock part 222.At this moment, the hole wall of this lock part 222 of clamping face a clip of this hook portion 113 axially moves up to prevent this hook portion 113, and then keeps lockup state, to guarantee sealing effectiveness.

As Figure 6 and Figure 7, when the sealing structure was extracted by this bottle 40, the user can help this bottle 40 on the other hand, and another hand rotates the compression leg 11 of this pressure part 10.At this moment, this hook portion 113 is rotated synchronously, and utilizes this dip plane b to break away from the lock part 222 of this central siphon 22 easily, causes in card base 112 resilient radial of this compression leg 11 and contracts, until these hook portion 113 temporary transient this lock part 222 and guide grooves 223 of breaking away from.Whereby, this elastic body 30 formation footpath synchronously inwardly contracts and axially replys length, and by the axial bottom surfaces 120 that this axial end face 32 axially upwards promotes this pushing portion 12, returns back to former position to axial of separating latch mode gradually until this pushing portion 12 and compression leg 11.Then, this elastic body 30 axially increase reply length during, if the user still continues to rotate this compression leg 11, then this hook portion 113 can be absorbed in arbitrary adjacent this guide groove 223 once more, and then axially is moved upward to and snaps in arbitrary adjacent this and separate till the door bolt portion 221.Like this, the sealing structure is promptly finished and is separated the door bolt action, and can be for being recycled and reused for this bottle 40 of sealing.

The present invention will be in other embodiment of the hermetically-sealed construction of hereinafter describing vessel port, and wherein partly member is identical with the hermetically-sealed construction of the vessel port of first embodiment, so same section employing same reference numerals, and its structure and function are given unnecessary details no longer in detail.
