Description

Packaging for foodstuff with seal cover cap

The present invention relates to have the packing that is used for food of resalable seal cover cap.Or rather, the packing that the present invention relates to comprises:

Container extends to the upper surface with opening along center shaft from the bottom, container has the peripheral surface of close opening;

Sealing system, it comprises the framework on the peripheral surface that is fixed on container, and is hinged on the lid that can move between open position and off position on the framework, the wherein said opening that covers closed container on off position; And at off position:

At least one contacts the container/frame frame sealing area that constitutes by the ring-type between the peripheral surface of framework and container; And

At least one by the lid with framework between ring-type contact the framework/lid sealing area that constitutes.

Such packing has user friendly sealing system, and can be used in food, for example holds Powdered, graininess or laminar food.In the example of baby milk, diaphragm seal is hedged off from the outer world milk powder fully, and must remove when using first, and milk powder remains in the container by sealing of lid then.

Document FR2747107A1 discloses the example of a kind of packaging for foodstuff of this type, and its lid is hinged on the framework that covers container top by elastic hinge.Document US 2006/0219652A1 discloses another and has had the example of the packaging for foodstuff of folding lid downwards, it has the articulation piece that the obstruction lid contacts with container and framework on the position relative with diameter, and the following locking member that can insert thumb.

Yet, can not always cover lid hermetically, at least can not with compare by the sealing that barrier film provided.Thereby after using first, when packing is placed temporarily the not time spent, have between lid and the framework even the very incomplete sealing of slight clearance, also can make fine particle-or under extreme weather conditions, under tropicalization, even small insect-contact with article.

Therefore, the purpose of this invention is to provide the packing of Reclosable, it can provide better protection for the article in the packing when the each lid of lid is tight.

In order to achieve this end, the invention provides the packing of the above-mentioned type, it is characterized in that, at described off position, contact the additional seal zone that forms at least one container/lid by lid with ring-type between the peripheral surface of container, this additional seal zone is between the opening and described container/frame frame and framework/lid sealing area of container.

In this way, may create a kind of packing that after opening first, can protect article again during cover lid fully.Except lid/frame seal contacts formed estrangement and framework/seal of vessel contacts the formed estrangement, lid also is favourable with the formed estrangement that contacts near the peripheral surface of opening part container.Equally, because the before nearest estrangement of lid and the formed sealing of the contact of the peripheral surface of container and article is consistent, when lid covers, avoided the interior article of framework and container to contact.Naturally, provide each ring-type contact by the continuum around packing (continuum), and term " sealing " should be understood to the integraty of splendid attire thing in the container.Under existing conditions, the sealing area of packing can not allow tiny insect enter between container and the seal cover cap, and this barrier action is applied to have the insect (for example lice psocid of larval phase) of the obvious characteristic of size about the 75-100 micron.

According to another feature, when lid was positioned at off position, each sealing area had the surface of plano-convex combination on cross-sectional plane, and this can stop the particle or the insect that have above 50 micron-scales to enter container.This between the surface very narrow contact type (if not point-like), can avoid indeterminate leak free to form, and reduce the user and operate the required strength of lid.

According to another feature, framework has the inside face that brings to few two annular surface, and this annular surface is used for contacting with the peripheral surface of container, and two mating surfacess are towards different directions, and defines two independent sealing areas.Thereby the cover frame frame is easy to cooperate with container, and allows certain tolerance in the manufacturing of container and framework.

According to another feature, lid has at least one Connection Element, and this attaching parts has two and is used for the annular surface that contacts with framework, and these two surfaces are towards different directions, to define two independent sealing areas.This makes lid be easy to cover on framework, and makes the certain tolerance of permission in the manufacturing of framework and lid.

According to another feature, the peripheral surface of container has lug, and when lid was positioned at its off position, this lug was between framework and described additional seal zone.Thereby container and framework and appear at arbitrary limit of lug like this with the contact area of lid preferably have on the surface portion of different gradients, and especially when covering when rising, framework can remain on the container.

According to another feature, the peripheral surface of container has the annular recessed portion of close opening, and frame cover and has following extending part outwardly from lid on described recess, this time extending part has certain distance apart from the peripheral surface of container, exists sealing ring to contact except terminal with container.The end of following extending part is the thickness of attenuate, thereby when lid is positioned at described off position, contacts with the sealing annular of container in the formation of the outside of described recess.The restriction of the sealing contact between framework and the container impels framework/cap assemblies to be assembled on the container, and container is preferably made by the technological process of the manufacture method that is different from framework/cap assemblies (as injection moulding) (as extrusion blow).

According to another feature, the following extending part of framework has outside face, and lid has sidewall, and this sidewall links to each other continuously with described outside face when off position.Therefore do not have the hand that framework/cap assemblies is met the user in the junction of lid.The smooth exterior surface facial contour of framework/cap assemblies can produce by outward flange and the butt joint between the frame outer that is formed by sidewall.This lid also preferably provides the additional space (especially height) of relative framework, thereby holds one or more article in the space that lid is defined.

According to another feature, lid comprises inward flange and outward flange, and inward flange has free terminal, and when lid was positioned at its described off position, the lid free terminal was pressed on the peripheral surface of container, to form described additional seal zone.Inward flange can have for example free terminal of inner inclination.Thereby when lid was depressed into off position, the end of inward flange slided smoothly along the peripheral surface of container.This set also has the centrally aligned effect, makes to seal accurately round opening when lid is closed.

According to another feature, lid has first annular groove that is formed between inward flange and the outward flange, and second annular groove that is separated by the outside annular projection and first annular groove, when lid is positioned at its off position, by the outside contact of annular projection formation framework/lid sealing area on the framework.This set guarantees to keep certain clearance in the middle of two sealing areas, at utmost reduce the quantity of making the required plastic material of lid simultaneously.

According to another feature, container is made by the extrusion blow moulding, and is the S type near the lateral cross section of opening, and the lower end of S type is corresponding to the zone that contacts with the following junction of framework.Thereby framework is shelved on the container by interface, and this interface separates from the sealing surfaces zone, guarantees not run through being used to.In addition, wipe surfaces is formed at the edge of vessel port, in the upper end of S.

According to another feature, lid comprises that the fastener that is oppositely arranged with articulation piece, framework have the outside cavity of radial face, and when lid was positioned at off position, fastener was bonded in this cavity, thus make cover shown in off position locking.Can not pass through the lock function of lid like this, and the junction and the framework that are implemented between these two elements keep sealing contact, thereby lid can be placed at outside this junction.

According to another feature, use the detouchable barrier film that described opening is sealed, when lid was closed, this barrier film tegmentum covered, and when lid was closed, this barrier film had at least one limit away from framework and lid.Barrier film can easily be removed like this.This barrier film is not preferably compressed by framework and/or lid.Because framework and lid have certain distance apart from the edge of opening, can also weld a measurer more simply.Especially, framework is positioned on the low plane of ratio open.

Other characteristics of the present invention and advantage in the description process that provides by means of non-limiting instance with reference to accompanying drawing below, become more clear, wherein:

Fig. 1 is that the lid that illustrates is in the closed position by the cutaway view according to the top of packing of the present invention;

Fig. 5 is the complete transparent view of the described packing of Fig. 1; And

Fig. 6 is the transparent view according to the top of packing of the present invention.

Identical Reference numeral is represented same or analogous element among the different figure.

With reference to Fig. 1 and 5, packing 1 comprises container 2 and sealing system 3.One end of container 2 relative base portions or bottom 20 has opening, and can be the arbitrary shape that it will be appreciated by those skilled in the art that, as cylindrical, taper, parallelepiped-shaped, waist shape etc.The annular sidewall P of container 2 extends to the top that is defined as upper limb 200 along vertical center axis Z.Defined by edge 200 by the periphery 22 wide openings 21 that surround.Periphery 22 can be from opening 21 downward simple crustal inclination, and is visual as the non-limiting example of Fig. 1, perhaps can be and the corresponding to horizontal surface in the plane of opening 21.

The cross section that container 2 is vertical with center shaft Z can be the basic rectangle with fillet.In the example depicted in fig. 5, some changes along center shaft Z in this cross section, and forming the waist shape of arresting easily, but these variations are limited to the vertical intensity of guaranteeing to pack when stacking.Take for convenience and hold, again, be connected to 150 in the cross section is preferably and arrive the rectangle of 130mm * 105 to 125mm.Height from the bottom to the end face is preferably between 130 to 170mm, with the normal volume of the box that is provided for holding baby milk.Therefore, the opening 21 of dark relatively container must be enough wide, to avoid near the trouble of taking out milk powder the bottom 20 of container 2.In addition, this wide opening 21 allows with the measurer D that takes out milk powder.

Because this basic rectangular cross sectional shape, as shown in Figure 6, the periphery 22 of the opening of container 2 can be considered as having the first long limit 22a, the relative second long limit 22b, and the first and second minor face 22c, the 22d that connect long limit.

Do not imply any restriction, container 2 can be moulded plastic components by single hot blow and make.These plastics are preferably multi-layer composition and constitute efficient oxygen barrier, and being used for the product as milk powder, yet container is certainly made especially metal or stratum board by other material.

With regard to milk powder, as shown in Figure 1, the opening 21 of container 2 is by barrier film 23 sealings, and this barrier film is along periphery 22 sealings.Therefore milk powder is stored in the container 2 with state in working order, and up to using for the first time, this moment, barrier film 23 was removed.

Can be clear that more that as Fig. 2 container 2 has neck 24 between the upper limb 200 of its annular wall 22 and middle top 25.Be formed with annular recessed portion 26 on this neck 24, thereby annular wall 22 is S-shaped on the cross section in opening 21 zones.Will introduce as the back, the appearance of this neck 24 matches with framework, and this framework is the part of sealing system 3.

With reference to Fig. 1 and 2, sealing system 3 comprises: at first be framework 31 and be dome-type lid 32 substantially.Framework 31 is fixedly mounted in around the neck 24 of container 2.Framework 31 is fixed on this position of container 2 non-dismountablely, and is fastening as adopting card to join, yet also can adopt bonding or welding to fix.In the nonrestrictive example shown in Fig. 1 and 2, framework 31 is joined in the annular recessed portion 26 that is fixed on neck 24 by card.Card is herein joined the periphery surface of fixing cyclic lug 33 by framework 31 against neck 24, promptly on downward surperficial 26a, on the outstanding limit of ring-type 300 times, realize by radially inner engagement.In case be installed on the neck 24, framework 31 is at least according to the translation along the Z axle at this moment, and surperficial 26a and last upper process and the lower process that forms of the relative 26b of showing by container 2 come fixing with respect to container 2.

In cross section shown in Figure 2, surperficial 26b is positioned at the lower end of the S of annular wall 22.For fear of between the surperficial 26b of container 2 and framework 31, producing statically indeterminate system, the preferred blowing-by of the contact of generation.In order to limit the zone of this contact, framework 31 can have edge 34, and its free terminal defines the unique surface that contacts with surperficial 26b.

In described embodiment, and do not imply any qualification, the annular container/framework between the free terminal of surperficial 26a and annular projection 33 contacts to the plano-convex type, and can define a sealing area.Annular recessed portion 26 is had the framework 31 that allows with lid 32 structures that are tightly connected by top and covers.

Remove and cover 32 be connected, framework 31 has bottom with neck 24 and separates at interval a following extending part E, exists sealing ring to contact C1 except terminal with container 2.This ring-type contact C1 is the contact that belongs to the convex surface of the smooth lip-deep framework 31 of the cardinal principle of container 2, as shown in Figure 2.Two narrow ring-type mating surfacess that define the framework 31 of container/frame frame sealing area are different directions in the example shown.The end of following extending part E can have the thickness of attenuate, thereby when lid 32 is positioned at described off position, sealing ring contact C1 is formed with container 2 contact.

Be provided at one or more container/frame frame sealing areas at neck 24 places; and at least one framework of bonded assembly/lid sealing area between the

element

31,32 of sealing system; when meaning the off position that is positioned on the framework 31 when lid 32, fine particle or small insect can not enter opening 21.Formed sealing ring contact C2 in distance container 2 a distance, for example the protuberance or the recess of the lid 32 that contacts at corresponding site with framework 31.

As illustrated in Figures 5 and 6, the following extending part E of framework 31 has visual outside face.Lid 32 has sidewall 32b, and this sidewall and this outside face keep continuity substantially when off position.Do not imply any qualification, at least one framework/lid sealing area can place distance extending part E a distance down.Special blocking device 4 shown in Fig. 2 and 6 can cooperate with sealing system 3.For example, this device 4 can be arranged on the outside of framework 31, adjoins extending part E down.

Between the opening of container 2 and above-mentioned sealing area, also has the auxiliary seal zone.Therefore, lid 32 can have circular element between edge 200 and framework 31, for example be attached to the inward flange S1 or the O type circle that covers on 32, and with the outside face formation direct contact C3 of neck 24.Sealing estrangement is near as far as possible from the opening of container 2, by the outside of the zone of auxiliary seal effectively direct contact to packing 1, makes article obtain better protection.The free terminal of inward flange S1 can for example be circle or oblique, makes milder the contacting of formation between the outside face of inward flange S1 and neck 24 when descending with box lunch lid 32.Preferably but do not constitute among the embodiment of qualification, when lid 32 was positioned at off position, the surface of plano-convex contact all appearred in each sealing area on the cross section.Shown in Fig. 1-4, the zone that constitutes sealing contact C1, C2, C3 all is an elastic variable.The generation in each annular seal zone can not reduce the comfort feature that covers 32 operations.

Major part in these sealing areas, all preferred, be to realize by applying power with cardinal principle radial component.

In an illustrated embodiment, framework 31 and lid 32 are hinged each other by attaching parts, this attaching parts allows cover 32 and moves relative to framework 31, and moves between the off position of open position that the opening shown in Fig. 3-4 and 6 21 is easy to enter and the 32 covering openings 21 of the lid shown in Fig. 1-2 and 5 relative to container 2.Its result forms reclosable packing, when so each use is packed, can operate its lid 32, for example when preparing beverage.

Attaching parts herein is an articulation piece 35, and its pivotal axis is vertical with center shaft Z.This is near the first long limit 22a of the periphery 22 in the example shown in Figure 6.Blocking device 4 can be provided with respect to articulation piece 35, near long limit 22b.In an illustrated embodiment, it is the plastics articulation piece 35 that is made of fold line, thus cover 32 and framework 31 can make one.Therefore, these elements of sealing system 3 can for example be made one by injection mo(u)lding in mould, as polypropylene.Yet articulation piece 35 is certainly made the fabricate block of two discrete items, and can use being connected of any suitable type between framework 31 and lid 32.In less preferred embodiment, framework/lid attachments can omit.

Come the attaching parts between framework 31 and the lid 32 now with reference to Fig. 2,4 and 6, and the lock of combination describes in detail.

As shown in Figure 2, and close place vertical substantially with annular projection 33, framework 31 has direct annular projection 36 towards the first groove g1, and it is defined at covers on 32, between inward flange S1 and sidewall 32b.This groove g1 is a ring-type, and narrower, and the average radial gap is less than 3 or 4mm.Groove 37 separates the sidewall 38 of annular projection 33 with framework 31.Near the attaching parts of lid 32, this sidewall 38 has defined the neighboring of framework 31, and the neighboring weak point that this neighboring can for example be defined than 31 times extending part E of framework perhaps equates.At off position, one or more Connection Element J of lid 32 just in time put into this groove 37.

With reference to Fig. 2, Connection Element J is a ring-type, and with inward flange S 1 parallel.(Jint Jext) towards different directions, thereby defines two independent sealing areas to the two ring-type bearing surfaces that herein contact with framework 31 between framework and lid.One of them bearing surface Jext can for example be made of the radially outer ring-type convex tendon among the embodiment shown in Fig. 2 and 4.The bearing surface Jint of another radial inward is defined by the contacts side surfaces between the smooth wall of near the nonreentrant surface that forms Connection Element J terminal and the cardinal principle that defines groove 37.In the embodiment shown in Fig. 2 and 4, this is the wall of the substantially flat that adjoins with annular projection 36.

The second groove g2 is defined in and covers on 32, between the sidewall 32b of Connection Element J and lid 32.This second groove g2 cooperates with the sidewall 38 of framework 31.The last end of sidewall 38 can converge with the transverse wall of groove g2.

As illustrated in fig. 1 and 2, sidewall 32b and inward flange S1 and form the arm of a Y shape on the plane above the opening 21, converge apart from transverse wall 32a a distance on vertical cross-section.

To cover 32 airtight lockings in order making, to have retainer 39 the relative edge of articulation piece 35, this retainer is for example for having the plate of a tooth or several teeth or at least one hook.These retainers 39 can protrude downwards, for example are parallel to attaching parts J, and can cover the little angular zone of the sidewall 38 of framework 31, with rib 40 point toothings that are formed on framework 31 outsides.

As shown in Figure 6, framework 31 herein has the cavity 41 of radial outward, and when lid 32 was positioned at its off position, retainer 39 meshed in this cavity.Cavity 41 can be communicated with the partial groove in the sidewall 38 of following extending part E, and defines the window that holds of the convex tendon that is used for respective shapes.Like this, the rectangular window shown in Fig. 6 can hold the convex tendon B of the inner general rectangular that forms of check plate.In case convex tendon B blocks in cavity and joins fasteningly, covers just locked.Locking realizes by promoting limit 42 with the lid all-in-one-piece on retainer 39 and in the first groove g1 adjacent areas with the release action.For release, the user is with pulling this lifting limit 42, thereby convex tendon B is pulled out its engage position.

With reference to Fig. 1,5 and 6, the retainer 39 of lid 32 can be provided with the jamproof system before using first.It can be that an end is used to point the detouchable band of catching 43.This band must shift out, thereby convex tendon B can be shifted out from itself and rib 40 position engaged.Therefore, as long as be appreciated that with 43 and remain on the position that retainer 39 is provided with, lid 32 just can not be from framework 31 separation.

The recycling and taking place under the following situation of packing 1: after whole sealing system 3 and locking and

antijamming feature

39,43 injection mo(u)ldings, the result be form one can be at off position and the single components that lid 32 disposes, make and cover 32 and be closed in downwards on the framework 31.Locking is supported this assembly with

antijamming feature

39,43 in this configuration.

The sealing system 3 of Huo Deing can be joined fastening easily be installed in (it at first is filled and uses diaphragm seal) on the container 2 by for example card then.Packing 1 then just can sell.Any attempt strikes the trial of holding packing with the hand all can destroy a breakable connection at least, therefore can easily be found by the customer usually.

When using first, the user can take apart from lid 32 and be with 43, and operation edge 42 is with its release.When packing 1 is closed after use once more, promptly be buckled in downwards on the container by covering 32, pin with regard to automatically joining to be fastened on the rib 40 by retainer 39 cards.Subsequently, in ensuing use, the user applies once more simply to upward pressure to and promotes on the downside on limit 42, just retainer 39 can be removed.

With reference to Fig. 1,5 and 6, measurer 100 is arranged on and covers 32 inside, and it can be hemispheric, and has certain height (for example between 2 to 5mm).Transverse wall 32a thereby higher than inward flange S 1.One or more parts, the measurer D during particularly as packing splendid attire milk powder, thereby can after being fixed on one or more joint elements 50, leave in the inner space.In an illustrated embodiment, between the transverse wall 32a of the inner space that is used to deposit measurer D when the opening 21 of container 2 and lid are closed.

Measurer D can be packaged in the sack at first, and be placed in the packing 1 diaphragm seal 23 with cover between 32, for sale.No matter the wall or lid 32 the wall that are framework 31 can not invade in the inner space of opening below 21 of container 2, so do not have from framework 31 or cover 32 pressure that are applied on the barrier film 23 that covers this opening 21.

Measurer D comprises the cup that links to each other with handle.The size of measurer, particularly length make it can be placed in the encapsulation position of framework 31.For the container 2 of circle, the length of measurer D certainly must be littler than the internal diameter of framework 31.

For fear of the various contacts that may destroy food, on the transverse wall 32a of lid 32, have independent taking and hold the zone, this zone is between two parties towards the centre, so that hold measurer D between the far-end of cup and handle.

With reference to Fig. 1 and 5, lid 32 can have with Fig. 1 in the corresponding symmetrical plane in cross section that uses.This symmetrical plane can comprise center shaft Z, and it passes the center of articulation piece 35, and passes the center on limit 42.Such plane also can separate two fasteners 50, to be used to fasten measurer, as shown in Figure 6.

Obviously; the above embodiments can not constitute qualification by any way; as to constituting sealing system 3 and locking and jamproof system or being used for the various distortion of geometric configuration of parts of the stop part 50 of glass D, all be possible, and do not depart from protection scope of the present invention.
