Description

Take off the tangible lid of back vestige

Technical field

The present invention relates to the lid of taking off back vestige obvious (tamper-evident) that a kind of container is used, this container comprises edge of opening, this edge of opening particularly is provided with the flange that forms with the cover plate that covers the upper container opening basically along the upper container aperture distribution; With the lid edge, this lid edge extends downward container from cover plate basically; And comprising locking piece at least in some position, this locking piece clamps the below of edge of opening, particularly can separate with lid definitely can make lid leave container with the feather edge end at lid edge.

Background technology

Such lid is disclosed among the US5002198A.Corresponding cover plate is arranged on the edge of opening from above, and the covering container opening.This cover plate connects from the lid edge that cover plate extends vertically downward.The lid edge is basically tangentially in abutting connection with container edge that curl or flange, and locking piece is from its free end projection, and end at edge of opening below, clamp basically simultaneously this edge of opening below.

For to take off the back vestige obviously or pry open tangible mode from the container relief cap, a part lid edge, particularly feather edge end are opened with locking piece is separated.After this, lid can be got rid of from container.Marginal end portion is separated definitely and can be guaranteed basically from the lid remainder with locking piece, even lid is motionless or when being again placed on the container, people can find also whether lid is removed by another user, perhaps prepares at least to remove.So just allow to detect any manual operation or any attempt of prying open or opening container.For example, such lid can prevent that cell therefor is opened, and contents are subjected to indescribable influence, is perhaps partly taken out, and container seals once more and needn't open the container that can confirm from the outside then.

But, in above-mentioned lid, there is a kind of possibility, be that manual operation occurs on the locking piece, so that locking piece can produce radially outwardly elasticity depart from up to locking piece no longer the grip containers edge below, even under the situation of not separating definitely in the feather edge end, lid also can discharge from container.In addition, vertically extending lid edge only can produce slight elasticity to be departed from, so that lid is when being placed on the container, locking piece must have sizable elasticity so that it can radially outward be departed from fully in the edge of opening zone of outwards curling.This sizable elasticity of locking piece allows to remove lid corresponding manually operate in: because the relatively large elasticity of locking piece self, its can be by crooked more easily, and lid can be removed from container then.

Summary of the invention

Therefore, the objective of the invention is the improvement of taking off the tangible lid of back vestige mentioned when this paper begun, lid is safe for the possible manual operation of locking piece like this, and this locking piece is removed lid in simply constructed mode, on the other hand, guarantee the closure function of lid.

Purpose of the present invention realizes by the feature of claim 1.

Particularly, the invention is characterized in and cover the edge, and locking piece is designed to lock-in edge and distributes on the circumferencial direction of lid basically from downward, the outward-dipping extension of cover plate.

By use around lock-in edge, can not laterally appear between the lid edge of lock-in edge and diagonally extending, for example, the joint below container edge discharges lock-in edge thus.By lid edge tilt ground downwards and stretch out, the lid edge also can flexibly depart from when lid is placed on the container, so that lock-in edge and lid edge can flexibly depart from when lid is placed on the container, so elasticity can not exist only in the zone of locking piece basically.

And, because the cause at the lid edge of diagonally extending,, cover under the situation at edge in operation simultaneously not for lid can be removed from container, lock-in edge can not form the distribution of perpendicular accordingly.On the contrary, tilt distribution by the lid edge, even it also can remain on certain bevelled position during the abutting cap edge internally in corresponding lock-in edge, move down the son of uncapping in situation without any visible trace so that may make it move past edge of opening hardly.

Like this according to the present invention just simply mode improve lid taking off back vestige palpability.Simultaneously, take off under the situation of back vestige palpability or leak tightness not reducing lid, by just realizing easily lid is placed on the container at lid edge or lock-in edge distribution elasticity.

According to the present invention, corresponding cover plate may have different shapes.On the other hand, cover plate corresponds essentially to the shape of vessel port along the geometric configuration of edge of opening.On the other hand, in the outside of edge of opening, for example, cover plate can be any other mode to interior curve, fold or the distortion of container, perhaps, also may correspondingly produce distortion away from container.The simple cover plate that is easy to make is the plane basically.Then, cover plate is placed on the container edge, and covers the entire container opening, thereby avoids external action, simultaneously the contents in the airtight container.

For example, for the ease of handling lid so that it leaves container, cover plate can comprise the edge projection that distributes in a circumferential direction, and lid edge projection perpendicular projects upwards.

The lid edge can direct connection plane cover plate or and adjoining edge projection.

With the direct coupled simple case of edge projection in, the lid edge comprises it being the upper marginal end portion of inverted U basically, the edge projection is inserted U type opening and also is fixed in this.The degree of depth of U type opening corresponds essentially to the vertical length of edge projection.Like this, the edge projection utilizes the corresponding U type leg of upper marginal end portion clamped at dual-side, for example, can be fixed on the both sides by gummed, heat-sealing and alternate manner.

The lid edge also can be equably from the top obliquely downwards and extend outwardly into the bottom.But, to cover the edge and be convenient to or improve fixing and sealing simultaneously in order to utilize, the lid edge on top comprises at least one upper edge and a lower edge portion between acies portion and its bottom, and they tilt to stretch out from cover plate respectively, and the middle edge portion by perpendicular connects then.This middle edge end can be specially adapted to from outside close edge of opening, so that lid itself can be installed on the container securely, also can be retained in the there even marginal end portion is left definitely.

This diagonally extending of staged basically at lid edge can make lid produce effect attractive in appearance on the optics, and lid can be easy to clamped more and is fixed on the container.

The lower edge portion of having mentioned above will be designed to it in such connection can be vertically extending between the bottom at lower edge portion and lid edge basically.Will produce the space between lower marginal end portion and wall of container like this, so that produce the manually-operated space of possibility, this wall of container is smaller under the situation of lower marginal end portion diagonally extending.

The extension of middle edge portion and lower marginal end portion perpendicular also can replace with some diagonally extending of these parts, and these parts are outward-dipping with the angle of inclination less than upper and lower edge part.

For the optical appearance and the manufacturing process of lid, further consider that the leaning angle of upper and lower edge part and/or centre are preferably identical with the leaning angle of lower marginal end portion.

Lower marginal end portion stable and therefore be equal to lock-in edge stable can have by design at least two-layer, the lower marginal end portion of promptly outer and internal layer and producing.Therefore, this lower marginal end portion has the rigidity of enhancing, on the one hand, has increased the operation easier of removing lid, on the other hand, has reinforced the intensity of lock-in edge.

In simple embodiment, lock-in edge can be designed to the extension of internal layer.In the case, for be clamped in the respective openings edge below, lock-in edge can be extended to container in the extension of internal layer simply.

This lock-in edge can directly be given prominence to the extension as internal layer in the zone of lower marginal end portion.But this internal layer also can extend to lower edge portion at least in part, and the corresponding leaning angle of this edge part is used for crooked internal layer, so lock-in edge deflection wall of container.

In the case, the leaning angle of lower edge portion can continue in lock-in edge equally, so that lid extends to container when fixing and being clamped in below the edge of opening with being inclined upwardly.

Point out: be used for offset from cover edge and lock-in edge and therefore lid be fixed in elasticity distribution on the container to lid edge and lock-in edge according to of the present invention.Only when lid was fixed on the container, lock-in edge is flexibly outward radial bending preferably.So at least with respectively from the outstanding lock-in edge part correlation of lower edge portion or lower marginal end portion.

As much as possible little for the free end and the space between the wall of container that guarantee lock-in edge, increase the operation easier of lock-in edge simultaneously, fixedly the time, lock-in edge can be provided with at its free end and be arranged essentially parallel to the cut end that wall of container extends at lid.Fixedly the time, this cut end also can be directly in abutting connection with wall of container at lid.The corresponding extension at cut end edge has increased the complexity of expansion, and thus at the free end of edge of opening by lock-in edge.

For uncover, the remainder of lower marginal end portion and lock-in edge and lid to determine to separate be necessary.In order to realize this separation in simple mode, tear device is from lid edge projection.A more than tear device also can distribute.For example, tear device can be roughly from lid edge-perpendicular projection, so that its side direction clamp cap edge easily can be used in the lid that separates appropriate section then.Tear device also can extend on the extension at lid edge in its bottom.

In order to utilize tear device to isolate in lower marginal end portion, in the zone of tear device,, in the lid edge, can form the auxiliary member of tearing of perpendicular particularly at the front edge of tearing on the direction with reliable and controlled way.If tear device is clamped then, move to and tear direction, at first cover the edge and isolated along the vertical auxiliary member of tearing, further realize basically the corresponding part at separate cover edge in a circumferential direction subsequently.

Tearing auxiliary member and can have different designs like this.Usually, it is designed to material decay line.This material decay line can be to make material attenuation or perforation etc.

Also in order to allow with corresponding part simple and the further separate cover of controlled way edge, even after separating this part, do not damage the outward appearance of lid simultaneously yet, in a circumferential direction the edge separation auxiliary member of Yan Shening can with lid edge at interval, its bottom in be approximately perpendicular to and tear auxiliary member and form, so that tear device moves to tearing direction, isolate tear auxiliary member after, the separation that further realizes covering the corresponding part in edge along the edge separation auxiliary member.

The edge separation auxiliary member can be designed to and tear the auxiliary member identical materials and weaken line.

Even in order under this connection, to guarantee to have the corresponding separated portions of covering the edge, lid is positioned on the container and utilizes and covers the edge and lid is retained in remain possible on the edge of opening, and the edge separation auxiliary member can be set to the ratio open edge and be close to the bottom of covering the edge more when lid is positioned on the container.So just guarantee after corresponding part is ripped, can keep enough parts of covering the edge its is extended downwards on edge of opening basically, might replace lid and lid is retained on the container reliably.

For lid, can use various materials in fact.Lid can be fully or is to be made by plastic material partly.So just can guarantee to small part be transparent or semi-translucent.This situation is specially adapted to cover plate.Therefore, the contents in the container are appreciiables.Basically the lid that is formed by one or more ply of papers causes being easy to making and reclaiming lid.And such ply of paper is easy to stay the marking that glass interior contents were used or were used to indicate in advertisement.

If the placement lid, because cover plate is to be used for protecting the infiltration that the contents that are included in container exempt from does not need material, but also the leakage of contents in the protection container, in the cover plate zone, the leak free plastic tab is arranged on its bottom end side at least.In addition, plastic tab for example comprises in container under the situation of liquid, can prevent that the ply of paper of lid, particularly cover plate are by soaked with liquid with may be subjected to optically influence.

Certainly lid or its one of them parts also may not be only to be made of a ply of paper, but by what interconnect, particularly stacked ply of paper constitutes.Point out: this structure is to be made of two-layer in the zone of lower marginal end portion at least, and wherein internal layer forms lock-in edge.Here, corresponding layer also can be a ply of paper.

In order be respectively to preserve the lid of closed container or after it was made, lid can pile up to deposit and can not pile up to be deposited in simple mode.

But this stackability and can not stackability, for example by covering the edge, the internal diameter of its bottom is realized greater than the external diameter of upper marginal end portion at least.Corresponding relation between internal diameter and the external diameter can also appear at lower marginal end portion, but may downward zone up to the lower edge portion that improves the lid stackability.

Because piling up lid so that pile up the end, for example by corresponding automated installation when complicated lid can not fixedly block, so lock-in edge just can be designed to pile up retainer, this piles up retainer from the outside, particularly when piling up lid from top in abutting connection with upper marginal end portion.

Tear direction 29 if tear device 27 moves to, cover so in the zone of front edge 28 that edge 6 just begins the tear device 27 on tearing direction 29 and break.In the extension at front edge 28 or other edge of itself, tear auxiliary member 30 and form material at lid in the edge 6 and weaken line 31.Its perpendicular extends upwardly to edge of opening 4.Edge separation auxiliary member 32 is at circumferencial direction 9 and also tearing on the direction 29 perpendicular to tearing auxiliary member 30 and extending.It also can be designed to material and weaken line.

By mobile tear device 27 to tearing direction 29, the bottom at lid edge 6 along edge separation auxiliary member 32 with lock-in edge 10 separated opening as locking piece 7 so that lid 1 can leave container 2, can be referring to Fig. 6 b and 7.

Corresponding part by the separate cover edge is to remove lid 1, and people can obtain pointing out the container 2 with lid 1 to be used, and perhaps is at least to attempt to remove earlier lid 1 from container 2.It is obvious so just to make lid take off the back vestige, just as the attempt of opening can be done, and can be detected by another user.

In Fig. 2, the details among Fig. 1 " X " amplification shows.Parts identical in all accompanying drawings all are denoted by like references, and part is only mentioned in a relevant width of cloth accompanying drawing.

Container 2 is provided with in the upper end of wall of container 24 to the edge of opening 4 of upper process.The cover plate 5 of lid 1 is arranged on its top side with bottom side 33.In the zone of edge of opening, cover plate 5 comprises the edge projection 11 that perpendicular projects upwards.Along this edge projection and bottom side 33, leak free plastic tab 34 is applied on the cover plate 5.The remainder of cover plate 5 and lid 1 can be formed by one or several ply of papers 38 in addition.Replace a ply of paper, two ply of papers particularly by stacked connection, correspondingly can also use one or several ply of boards etc.

The lid edge 6 of lid 1 connects cover plate 5 by its edge projection 11.Lid edge 6 is from cover plate 5 downward and outward-dipping extensions.

Lid edge 6 comprises upper marginal end portion 12.Upper marginal end portion 12 is roughly inverted U.Edge projection 11 is inserted in the corresponding U type opening 13, and is fixed between the corresponding U type leg.

On top after the acies portion 12, lid edge 6 also comprises upper edge 15, middle edge portion 17, lower edge portion 16 and lower marginal end portion 8.Upper and

lower edge part

15 and 16 stretches out with the angle of inclination with respect to container 2.Middle edge portion 17 and lower marginal end portion 8 are inclined upwardly less, and can perpendicular extend, referring to Fig. 6 a to 7.

The upper edge 15 at lid edge 6, middle edge portion 17, lower edge portion 16 and lower marginal end portion 8 form the ladder basically at the lid edge that extends to its lower end 14.

The corresponding leaning angle of upper edge 15, middle edge portion 17, lower edge portion 16 and lower marginal end portion 8 as shown in Figure 3, referring to

reference number

18,19,20 and 21.

About upper and

lower edge part

15 and 16 bevelled

angles

20 and 21, and middle edge portion 17 and lower marginal end portion 8 bevelled angles 18,19, they may be identical, also can be referring to Fig. 4 a to 7.In another embodiment, referring to Fig. 3, angle of inclination the 20, the 21st, different, particularly angle of inclination 21 is greater than angle of inclination 20.

Different angles of inclination is respectively that the vertical and corresponding respective angles between outward-dipping by respective edges portion produces.

In the zone of middle edge portion 17, edge separation auxiliary member 32 can be seen below edge of opening 4.It with the distance of the bottom 14 at lid edge 6 than shorter with the distance of the bottom side of edge of opening 4.Even so just guarantee that part lid edge 6 is separated along edge separation auxiliary member 32, lid 1 also can be positioned on the container 2, and also is possible by its inboard with lid edge 6 on the edge of opening 4 in abutting connection with lid is retained in correspondingly.

Lower marginal end portion 8 is designed to basically by outer 22 and the bilayer formed of internal layer 23, also referring to Fig. 3.This double-decker by folding or crooked outer extension as internal layer to outer field inside with in lower marginal end portion 8 zones, produce corresponding connection of double-ply at least.As for other parts, internal layer 23 is continuities of outer 22.Internal layer 23 extends to lower edge portion 16 with angle of inclination 21, and correspondingly inwardly and extends to cover plate 5 with being inclined upwardly.Internal layer lower edge portion 16 with extend to wall of container 24 basically after the remainder at lid edge 6 separates, form lock-in edge 10 thus as locking piece 7.Lock-in edge 10 is extended around entire container 2 on circumferencial direction 9.

The free end of lock-in edge 10 be clamped in edge of opening 4 below, and when lid 1 is placed on the container 2, be in close proximity to the outside of wall of container 24, perhaps it can be in abutting connection with wall of container.

Referring to Fig. 3, can in the outside of wall of container 24, realize the butt joint (abutment) of the free end 25 of lock-in edge 10, so that after lid 1 correspondingly is placed on the container 2, free end 25 can be further by in abutting connection with wall of container 24 bendings to edge of opening 4, thereby improve 1 the palpability of unliding.The degree that departs from realization under this connection will make the free end slit 39 between coupling opening edge 4 and the wall of container 24 at least in part basically.

When lid 1 was placed on the container 2, lid edge 6 can be at least with lower marginal end portion 8, lower edge portion 16 and middle edge portion 17 and the outwards expansion of lock-in edge 10 resilient radial ground, so that it can be passed along edge of opening 4.In case free end 25 arrives the bottom side of edge of opening 4, because the elastic reaction of lid edge 6 and lock-in edge 10, it just is pressed towards wall of container 24, particularly is pressed in the edge of opening 4 and the gap opening 39 between the wall of container 24 of projection.

In Fig. 4 a to 4c, demonstration be that corresponding lid 1 is placed on the different step on the container 2.In these steps, particularly can see departing from of lock-in edge.

In the lid 1 according to Fig. 4 a to 4c, the angle of inclination that particularly can see upper and lower edge part and middle edge portion and lower marginal end portion is respectively identical, and middle edge portion and lower marginal end portion perpendicular are extended.

And, can see that in Fig. 4 a to 4c lid 1 in the zone of acies portion 12 on top is positioned at the structure on its outside.This structure is by the many impressions that distribute on circumferencial direction 9 respectively and the formation that raises.

In Fig. 3, particularly can also see the external diameter 36 of the internal diameter 35 of lower marginal end portion 8 greater than upper marginal end portion 12.So just allow to pile up at least two lids 1, so that the upper marginal end portion 12 of following lid is inserted in the top lid up to the bottom side of lock-in edge 10, also can be referring to Fig. 5.Lock-in edge 10 forms in according to the embodiment of Fig. 3 piles up retainer 37 at least, this pile up retainer 37 from top and stay down the upper marginal end portion 8 of lid 2 from the outside basically on.

In according to embodiment shown in Figure 5, lower marginal end portion 8 and upper marginal end portion 12 perpendicular are extended, so that the lid that piles up distributes successively and can accurately assemble, below lid be inserted in the upper cover, up to it roughly with the bottom 14 of upper cover till the upper edge 15.

In Fig. 6 a and 6b and Fig. 7, demonstration be another embodiment of tear device 27.In Fig. 6 b, the separable portion at lid edge 6 is separated to small part.

This situation is equally applicable to Fig. 7, and in the present embodiment, tear device 27 can not form the separating part that covers edge 6 basically, but is arranged in abutting connection with tear line 30 by part lid edge 6.

About the respective shapes of the cross section of container and same lid, be noted that they can be circular, avette, oval-shaped, foursquare and rectangle etc.In having the embodiment at turning, circular edge is favourable.

And, should be noted that not only lid 1 can be placed on the container 2 owing to cover the elastic reaction of edge 6 and corresponding lock-in edge 10.And container 24 has elasticity respectively at least in part in the zone of edge of opening 4 or wall of container 24 usually, so that container also can produce elastic deformation when lid is placed.

In embodiment, should be noted that the corresponding angle of inclination of lock-in edge 10 is identical with the angle of

inclination

20,21 of upper and lower sloping

edge portion

15,16 basically according to Fig. 4 a to 7.Here, corresponding angle of

inclination

20,21 is also substantially the same, and

other edge part

12,17,8 does not tilt, and perpendicular is extended.

In the embodiment according to Fig. 4 a to 7, another difference just is that cover plate 5 extends radially outwardly into the bottom of upper edge 15 basically, and the outline of showing edge of opening 4 greatly finishes.Will produce improved sealing effectiveness by cover plate 5 like this.And, compare with Fig. 4 c, between lid edge 6 and edge of opening 4, have less slit, for example see Fig. 2.

In the embodiment according to Fig. 4 a to 7, the free end 25 that has shown lock-in edge 10 especially is how to engage gap opening 39 between wall of container and the edge of opening 4.
