Packing with sealing area

Technical field

The present invention relates to have the packing of sealing area, the sealing zone comprises and packs rigidly connected lid and cross the seal cap that lid and relative lid maintain, both respectively comprise the opening of emitting that can accurately aim at lid and seal cap, seal cap comprise can with emit the closed region that opening is accurately aimed at.

Background technology

From a kind of as can be known such packing of DE 197 06 112 C2.In being described to the known package of beverage can especially, this has such problem, promptly after filled drink jar and crimping engage cover, the fluid that is filled in the beverage can may arrive between lid and the seal cap, and this is because there is not the opening in the sealing lid before applying seal cap.The other problem of this known package also is: in fact can not clean the lid that is polluted before applying seal cap and make the material of having packed not be subjected to the pollution of stain remover or dust, and be difficult to arrange the intelligible tamper-evident enclosed construction of end user, especially be difficult to not increase any parts and arrange such structure.Such packing is particularly suitable for dumpable or flowable product.

Summary of the invention

The purpose of this invention is to provide packing so that this packing of can and apply lid and with after-applied seal cap after, the product of can not arrive between lid and the seal cap.Another object of the present invention is: lid seals when guaranteeing to clean after filling and package, and the production of guaranteeing tamper-evident enclosed construction.

Based on the packing of the above-mentioned type, can realize this purpose according to the present invention by this way: by the opening of emitting in the packing element sealing lid, the sealing element can be rendered as state that packing element partially opens at least so that packing is emitted.

As the part situation in the can flow liquid process, to pack excessive can when preventing from the process of crimping engage cover, to hold back any air or gas, in present embodiment according to the present invention, seal by packing element because emit opening, can't arrive lid by emitting opening so can guarantee fluid.

Do not have the fluid can be after applying seal cap between lid and seal cap, thereby can avoid all problems relevant with health.Under the situation that adopts pourable products, the present invention is particularly favourable, because the product particle that is interfered without any the avidity that may cause seal cap between lid and seal cap.

Can have any shape of wanting with packing bonded assembly lid.Important aspect is that shape is chosen to seal cap can move with respect to lid.Under the situation that adopts the Long Circle packing, oblong lid is suitable, wherein makes seal cap be lateral to the lid displacement.Consider that a large amount of beverage cans as packing are round, when with packing bonded assembly lid be that circle is favourable.This can reverse to expose or to seal seal cap with respect to lid and emits opening.

This is why to advise seal cap is held in rotating reason in another development form.

Seal cap can be fixed on the lid with holding device.For this purpose, independent connecting panel (web) just is enough to arrange there the function of seal cap.Yet, when sealing area comprises the seal cap that is overlapped in whole lid, be favourable.This can assist in ensuring that seal cap stability especially, and can be provided for arranging that many possibilities of seal cap are to arrange various functions there.

In configuration aspects, especially under the situation of dome, when lid and seal cap respectively comprise that off-centre is emitted opening, be particularly favourable.

When will harder material being used for seal cap and lid, when the emitting opening and surround this sealing area of emitting opening and be associated of lid, be favourable,

When the closed region of seal cap is associated with the sealing area that surrounds this closed region is favourable.The sealing zone can be arranged on lid and the seal cap.It can be between lid and seal cap or with the layout of lid and/or seal cap all-in-one-piece mode.

Be favourable when sealing area comprises sealing member.Sealing member in this case should not be understood that independently sealing member, but should be understood that it is the zone of generation special seal effect of special arrangement of lid or seal cap.

Even when mentioning sealing area within the scope of the present invention, do not get rid of yet and whole lid or whole seal cap can be provided with Chengdu and make to realize desired sealing by material with sealing characteristics.

One special embodiment is arranged on the lifting mechanism that acts between lid and the seal cap, and when reversing seal cap, this lifting mechanism causes removing the sealing function of the sealing area between lid and the seal cap.

When packing element is flexible, be favourable.This with regard to allowing because the overvoltage in the packing or owing to the pretension that is applied in being connected between seal cap and the lid produces distortion.If elastic seal cap arrives the opening below in the seal cap, then elastic seal cap can stretch into such opening.This can help to clamp packing element or utilize seal cap to act on the packing element.

Although in the lid emit opening and packing element aspect their shaping almost without any restriction, when packing element in another development form of the present invention with respect to packing with cap shape form to outer lug and be favourable when comprising at least one flange that radially projects into the outside.

For example when being provided for opening the handle of packing element, be proved to be favourable to the structure of outer lug.When handle is rigidly connected in packing element or be integrally formed in the seal cap, be favourable.After seal cap is torqued into open position, press to the outside to the opening of emitting that the cap of outer lug passes in the seal cap, can more easily catch the handle that is used to open packing element by this cap.

When packing element comprises predetermined fracture location, then be convenient to packing element is transferred to the state that partially opens at least.Can be arranged to packing element and only partly open, perhaps predetermined breaking portion also can allow packing element to open fully.

At handle integrally formed with seal cap and especially be arranged as in the shaped portion of seal cap and the twist process at seal cap with situation that packing element cooperates under, it also is favourable that predetermined fracture location is set.As a result, in the time of in the twist process of seal cap, packing element can be transferred to the state that partially opens at least, particularly can shift with predetermined fracture location.

Handle also can be used as punching tool and remains in the seal cap with movable manner.In order to open packing element, need after reversing seal cap, push punching tool downwards to open position, can be by this punching tool and seal cap is cut off partially or completely according to the structure of its blade.

Packing element can be fixed on the inboard or the outside with flange.

The mode that is received in the borderline region with opening between two flanges of packing element in the lid also can obtain advantageous embodiments.This structure is that favourable reason is, on the one hand, the packing element mode of rigidity especially is arranged on the lid, and on the other hand, in the detent position of this structure lower seal cap, top one in two flanges can be used as the closed region that sealing member surrounds seal cap.Such hermetically-sealed construction is followed such advantage, promptly also has closely between sealing member and the lid in this case to be connected.

When seal cap comprises in the closed region when being used for admitting the depression of packing element at least in part, then this is particularly favourable at packing element under the situation of outer lug with the form of cap.In the sealing element is received in position in the depression of seal cap at least in part, can in the twist process of seal cap, especially easily destroy packing element to open.

Seal cap can be made by such material: this material helps surrounding sealing member and the closed region that emits opening to arrange with seal cap all-in-one-piece mode.

Seal cap also can all be fixed in sealing member and closed region that opening is emitted in encirclement.In this case, when sealing member partly is embedded in the depression of seal cap, be particularly favourable.

When packing element is particularly favourable when the open mode maintenance is connected with lid, this is that such emitting together is being particularly disadvantageous from the beverage can of beverage can beverage directly because can prevent cut sealing member part like this emits with the content of packing.

In the present embodiment advantageously, packing element utilizes pretension to project in the packing after opening, and does not cause any interference in the process thereby can not emit in packing.

The mode of suggestion to substitute or to add up, in the motion process of seal cap with respect to lid, packing element cooperates with holding device on being fixed on seal cap.This allows but the cut-out or the cut-off parts of packing element are remained on the seal cap, makes it can not fall into packing and can not fall into environment Anywhere.Holding device can be before cutting off packing element at least a portion of clamping packing element or packing element, even if in cutting-off process, keep it and preferably after it is cut off, also can keep it.

When being latched on the described seal cap after packing element is being opened is favourable.By this way, the cut-off parts of packing element or packing element will be suspended on the seal cap rigidly, and it is held in the mode that is hitched as far as possible there.

Lifting mechanism comprises latching cam that is arranged on lid or the seal cap and the locking depression that is arranged on the parts that correspondingly are associated, and the locking depression that latching cam and association join is determined two positions of seal cap by their geometry, on these two positions, aspect is two and emits opening and be that the closed region of seal cap is aimed at the opening of emitting in the lid on the other hand.This structure not only can guarantee seal cap with respect to the motion process of lid in the essential lifting of seal cap, and can determine two control positioies of seal cap simultaneously, open fully a position and in the another location complete closed thereby guarantee to be packaged in.

In order especially to be convenient to packing is emitted when adopting fluid, or in order to accelerate the process of emitting, second opening is set in another embodiment of the present invention, this second opening is sealed by preferably elastomeric second packing element.When packing element being destroyed, this second opening is just as vent openings.

When with second aperture arrangement in the lid with emit opening relative basically to sector region (sector) in the time be favourable for venting process.By this way, can in the process that packing is emitted, particularly advantageously allow air to flow into.

In order to open the packing element that is used for second opening, be favourable when seal cap is provided with when the open position of seal cap pierces through second packing element and opens its projection.

Is particularly favourable when seal cap is included in detent position when sealing another sealing area of second packing element.Usually second packing element that is used as breather in the process that fluid is emitted is opened after it is by opening and thereby permission fluid outflow.Preferably be arranged as this another sealing area of a leak free and especially when the sealing beverage can, allow the opened packing element of sealing.

The various possibilities of opening packing element can be arranged.The possibility of the drift that maybe can be pressed into except the described handle that can extract out, also can there be on even keel to cut off the possibility of packing element.For this purpose, the suggestion seal cap comprises blade.

One simple embodiment is arranged in to emit arranges blade in the opening.When packing element enters when emitting opening, available blade cuts off it.The content of packing then, seal cap rotated backward once more slightly, so can flow out by emitting opening.

In actual treatment, confirm, when being favourable during tip arrangement in another opening at seal cap packing.As a result, can the function and the functional separation of emitting the packing content thing of a sealing member part will be cut off.

It is slotted hole that one simple embodiment is arranged to above-mentioned another opening.This makes the packing element of aiming at slotted hole enter opening and to open packing element by the motion of seal cap with respect to lid.

When in packing, transporting such as containing CO ₂The pressure fluid of beverage and so on the time, produce the pressure of some crust through regular meeting.When the closed region at the detent position back seal cap of seal cap was pressed against on the sealing member, the sealing member of arranging in the mode of less stable can bear such pressure.

Can realize being fixed in the blade of seal cap like this joins in the particularly simple association of one between the sealing member: in the motion process of seal cap with respect to lid, a part that has the sealing member of pretension projects in the opening of seal cap.Here, sealing member can be endowed pretension by special distortion, and perhaps exerting pressure against sealing member by seal cap is in the state that has pretension in sealing member projects into the opening of seal cap.

When this part of the sealing member that has pretension is takeoff in the opening of a position, especially seal cap in the motion process of seal cap with respect to lid with sending the sound is particularly favourable.The sealing part with " thump " sound jump in the opening, it is cut off by the motion of seal cap with respect to lid subsequently.Aud. snl. also can be realized like this: sealing member is jumped in the depression in the seal cap, and thereby preferably indicates the ad-hoc location of lid with respect to seal cap in the mode of sending the sound.

For the ease of at desired location cutting sealing part, be arranged to packing element and comprise and be used for the circumferential weakened part that cooperates with blade.

When opened sealing member formation lid and the sealing area between the seal cap is further favourable.Must be noted that in this respect, even if after a part of removing sealing member, also stay the leakproofing material that the sealing part is opened in enough being used to, to guarantee the abundant sealing between lid and the seal cap.

For the cut part of the sealing member that prevents loss, seal cap can comprise the opening that has lid.Like this, this lid is formed for admitting the cavity of at least a portion of sealing member.This lid can arrange integratedly with seal cap, or can be used as additional parts and be connected with seal cap.The opening that preferably can be arranged to have blade comprises lid.Especially have in packing under the high-voltage situation, can prevent like this that the sealing member of aiming at the opening in the seal cap oneself from opening or open and the fluid spilling goes out in uncontrolled mode, perhaps the part of sealing member ejects under the accelerating action of pressure.

Especially when being provided for cutting off the special opening of sealing member, advantageously the aperture arrangement of emitting in sealing member and the seal cap is become sealing member not pierce through to emit opening.

Provide the function of opening sealing member and function that packing emitted for lid hydrodynamic reciprocating sealing cap with correct order in order to ensure green phase, suggestion only can be moved seal cap along a direction with respect to lid.

Known in practice when the distance that emit between opening and another opening be favourable less than the diameter of sealing member.This makes seal cap can be placed on any position of wanting on the lid.

When seal cap comprises that the embossed portion timesharing that is used for information can be provided for advertisement or about the special possibility of the information of the condition of package encapsulation.

When seal cap is made by multi-component material, be favourable then to production.This allows for the connection seal cap and lid provides particularly solid material, then can require other material character to sealing area.

Therefore an advantageous embodiments is arranged to seal cap and is comprised the metal framework that has plastic insertion piece.

Do not need packing element flexible for many embodiment.Then, when the packing element deformable then be favourable to be positioned to when the seal cap.This permission is supported packing element at closed state with seal cap.

In this respect, preferably be arranged to packing element and comprise the framework that is sealed on the seal cap.
