Description

Tamper-Evidence Cover {TAMPER-EVIDENT LID}

FIELD OF THE INVENTION The present invention relates to a tamper-evidence cover for a container, comprising a container comprising an opening edge along a periphery of the upper container opening and especially widening to substantially cover the upper container opening, and essentially downward from the lid portion to the container. And a locking element clamped under the opening edge, at least in some locations, which can be clearly separated from the lid, in particular with the lower edge region of the lid edge for removing the lid from the container. will be.

Such a cover is known from US patent US-A-5002198. The corresponding lid portion is located on the opening edge from above and covers the container opening. This cover portion is connected to a cover edge extending vertically downward from the cover portion. The lid edge is adjacent adjacent to the container edge which is inherently curled or widened, and the locking element protrudes from its free end and ends below the opening edge which is essentially clamped down.

In order to separate the lid from the container in a tamper- or break-open-avid fashion, the lid edge portion and in particular the lower edge end region are separated together with the locking element. As a result, the lid can be removed from the container. Clear separation of the edge end zone with the locking element from the rest of the cover ensures that it is possible to find out whether the cover has already been removed or at least ready for removal by another person, even if the cover is intact or repositioned. Do it. This allows you to break open or attempt to open any operation or container. Such a lid, for example, opens the corresponding container, prevents the contents from being somewhat influenced or partially taken out, and prevents the opening of the container from closing again invisibly from the outside.

In the above-described lid, however, the locking element can be manipulated so that the lid can be flexed radially outward so that the locking element no longer clamps below the vessel edge and the lid is separated from the vessel without a clear separation of the lower edge end region. have. In addition, since the vertically extending cover edges can only bend slightly resiliently, the locking element has a correspondingly high elasticity when the cover is positioned above the container so that it can sufficiently bend radially outward in the outwardly curled opening edge region. have. The relatively high resilience of this locking element allows for a corresponding operation for removing the cover so that the cover can be bent outward more easily due to this relatively high elasticity of the locking element so that the cover can be subsequently removed from the container. do.

Since the object of the present invention is to improve the tamper-evidence cover of the type mentioned earlier, it is safe for possible operation of the locking element for removing the cover in a structurally simple manner, while ensuring the closing function of the cover. .

This object is achieved by the features of claim 1.

The invention is in particular characterized by a locking element which is made as a cover edge extending essentially inclined downwardly outward from the cover part and a locking edge extending in the circumferential direction of the cover.

By the use of an enclosed lock edge, it comes from the side between the lock edge and the inclined elongated lid edge, for example there is no possibility of separating the lock edge from the engagement below the container edge. By extending the cover edge inclined downward outwards, the cover edge can also be elastically bent when the cover is covered, so that not only the cover edge but also the locking edge can be flexed when the cover is covered and the elasticity is essentially a locking element It only exists in the realm.

In addition, with the inclined elongated lid edge, the corresponding locking edge cannot be made essentially vertically aligned without manipulating the lid edge to somehow remove it. Instead, the tilted arrangement of the cover edges ensures that the corresponding locking edge is held in a constant tilted position even when adjacent to the inside of the cover edge, thus moving past the opening edge to remove the cover without any visible trace. It is almost impossible to let it.

This increases the tamper-evidence of the cover according to the invention in a simple manner. At the same time, positioning on the lid over the container is facilitated by the distribution of resilience on the lid edge and the locking edge without reducing tamper-evidence or the firmness of the lid.

According to the invention, it is possible for the corresponding lid portion to have various forms. On the one hand the geometrical shape of the lid portion along the opening edge essentially corresponds to the shape of the container opening. On the other hand, the lid portion outside the opening edge is, for example, curved and it is possible to clamp or otherwise deform into the interior of the container, or correspondingly away from the container. Simple cover parts that are easy to manufacture may be essentially planar. The lid is then placed on the container edge to cover all of the container openings to ensure the same for external influences and at the same time to seal the contents of the container.

For example, the lid portion may comprise an edge flange that is circumferential and protrudes essentially vertically to facilitate handling of the lid to remove it from the container.

The lid edge can be connected directly to the flat lid portion or to the edge flange.

In a simple example of direct connection with the edge flange, the cover edge comprises an inverted U-shaped upper edge end region, an edge flange inserted into and fixed to the U-shaped opening. The depth of the U-shaped opening can essentially correspond to the longitudinal length of the edge flange. In this way, the edge flange can be clamped by the U-shaped leg of the corresponding upper edge end region and fixed to it, for example by gluing, heat sealing or otherwise.

The lid edge is likely to extend evenly from the top to the bottom end inclined downward outward. However, in order to facilitate or improve the sealing at the same time while covering with the lid edge, the lid edge extends outwardly from the lid portion between the upper edge end region and its lower end, respectively, and extends outwardly by an essentially vertical middle edge region. It may comprise at least one upper and one lower edge zone connected. This intermediate edge end region can in particular be adjacent to the opening edge from the outside, so that the lid itself can be securely seated on the container and can be fixed there even if the edge end region is clearly separated.

This inherently stepped extension of the lid edge becomes a visually advantageous appearance with respect to the lid, and the lid can be clamped more easily and placed over the container.

The already mentioned lower edge end region can be made with this connection so that it extends essentially vertically between the lower edge region and the lower end of the lid edge. This makes the space between the lower edge end zone and the container wall smaller than in the case of the inclined extension of this lower edge end zone, so there is less maneuverable space.

The essentially vertical extensions of the middle edge region and the lower edge end region may be replaced by certain inclined extensions of this region, which extend inclined outwardly with a smaller inclination angle than the upper and lower edge regions.

It is further contemplated that for the visual appearance and manufacture of the cover it is advantageous that the inclination angles of the upper and lower edge zones and / or the lower edge end zones of the intermediate end zone are equal.

Stabilization of the lower edge end region and equal stabilization of the locking edge can be obtained by making the lower edge end region of at least two layers, namely the outer and inner layers. As such, this lower edge end region has increased rigidity on the one hand which complicates the operation of removing the lid and on the other hand reinforces the locking edge.

In a simple embodiment, the locking edge can be made as an extension of the inner layer. In this case, the extension of the inner layer simply extends in the direction of the container to clamp under the corresponding opening edge.

The locking edge may project directly as an extension of the inner layer in the lower edge end zone region. However, there is a possibility that this inner layer extends at least partially into the lower edge region and the corresponding inclination angle of this edge region causes the inner layer and the locking edge to bend towards the container wall.

In this case, the angle of inclination of the lower edge zone equally follows the locking edge, so if covered, it extends obliquely upwards towards the container wall and clamps below the opening edge.

According to the invention the elasticity of bending the lid edge and the locking edge and also the elasticity for covering the lid over the container are distributed to the lid edge and the locking edge. It is an advantage that the locking edge can be elastically bent radially outward when the lid is just covered on the container. It is respectively associated with a locking edge portion protruding from at least the lower edge region or the lower edge end region.

In order to ensure the space between the free end of the locking edge and the container wall as small as possible and at the same time complicate the manipulation of the locking edge, it has an end edge of the cut which extends essentially parallel to the container wall at the free end when covered. Can be. This end edge of the cut can also be directly adjacent to the vessel wall when covered. Corresponding extensions of the end edges of the cuts complicate the diffusion and passing of the free ends of the locking edges at the opening edges.

To open the lid, clear separation of the lower edge end region and the locking edge from the rest of the lid is required. In order to be able to do this in a simple way, the tearing device can protrude from the lid edge. It is also possible to arrange more than one tearing device. The tearing device, for example, protrudes approximately vertically from the cover edge, so that it can be easily clamped to the side of the cover edge and can be used to separate the corresponding part of the cover. The tearing device may also extend from its lower end to an extension of the lid edge.

In order to allow tearing in the tearing device area and in the tearing direction, especially at its front edge, in a manner secured and controlled by the tearing device in the lower edge end region, an essentially vertical tearing lead can be formed at the lid edge. When the tearing device is caught and moved in the tearing direction, the lid edge first tears along the vertical tear aid line, and then subsequent separation of the corresponding portion of the lid edge is essentially circumferential.

Such tear tear lines can have a variety of structures. Usually, it is made as a material weakening line. Such material weakening line can be made thinner, perforated, etc.

In order to allow removal of the corresponding part of the cover edge in a simple and controlled manner and at the same time not to damage the appearance of the cover even after this part has been removed, the circumferentially extended edge tearing extension line is separated from its lower end. It is formed essentially perpendicular to the tear auxiliary line on the spaced lid edge. This auxiliary line crosses the vertical tearing line, so that when the tearing device is moved in the tearing direction, subsequent separation of the corresponding portion of the cover edge after the tearing line is torn along the edge tearing line.

Edge tearing lines can be made as material weakening lines similar to tearing lines.

In order to make it possible to cover the lid over the container and the correspondingly separated part of the lid edge in this connection, and to secure the lid from the opening edge to the lid edge, the edge tearing support line is provided with the opening edge when the lid is covered on the vessel. May be arranged closer to the lower end of the lid edge. This ensures that a sufficient portion of the lid edge remains after the corresponding portion has been torn, extending essentially beyond the opening edge to replace the lid in the container and allow for secure fastening of the lid.

As the cover, essentially various materials can be considered. The cover can be made entirely or partially of plastic material. It may be at least partially transparent or translucent. This is especially applicable to the cover part. Thus, the contents of the container can be seen visually. Covers that are easy to make and easy to recycle may come from covers that are essentially made of one or more layers of paper. In addition, such paper layers can be easily printed for advertising purposes or to give an indication of the contents of the cup.

When covered, the cover portion prevents the contents contained in the container from not only infiltrating unwanted materials but also from leakage of the container contents, so that at least in the cover portion region liquid-tight plastic foil can be applied to its bottom side. Such plastic foil additionally prevents the paper layer of the lid and in particular the lid portion from being submerged in liquid and somehow visually affected, for example in the case of liquid contained in a container.

It is of course possible that the cover or one of its parts consists of connected, especially laminated paper layers, not just one paper layer. It has already been pointed out that the structure consists of two layers, at least in the region of the lower edge end region, and the inner layer forms a locking edge. Here, the corresponding layer may be a paper layer.

To store the lid in a simple manner to close the container or after its manufacture, the lid may or may not be stacked, respectively.

Such stackability and non-stackability can be achieved, for example, by the inner diameter of the lid edge where the lid edge is at least at its lower end than the outer diameter of the upper edge end region. The corresponding relationship between the inner diameter and the outer diameter is also present for the lower edge end region and can go down to the lower edge region region to possibly improve the stackability of the cover.

The locking edges are secured from the outside to the upper edge end region from the outside, especially if the lids are stacked, so that the lids are stacked, for example, when such an end layer is complicated by corresponding automatic operation. It can be made as an adjacent stack stop element.

FIG. 6B is a view showing the cover partially torn open according to FIG. 6A.

1 shows a side view of a partial cross section of an embodiment of a lid 1 according to the invention.

The container 2 has a container upper opening 3 surrounded by an opening edge 4 that is widened outward, as also seen in the other figures. At the lower end, a portion of the bottom surface is inserted and held inside the container 2 and sealed by the end section of the container wall 24 bent inward in a known manner.

The lid 1 is located at the top of the container. The cover comprises an essentially planar cover portion 5 lying in a sealed manner on the opening edge 4 from above. The lid 1 also has a lid edge 6 extending from the lid portion 5 inclined downwardly outward. The lid edge 6 extends along the opening edge 4 in the circumferential direction 9 around the container. In the lid edge 6, particularly at the lower end 14, a tearing device 27 is arranged, as shown in FIG. 2. The user can grasp this and move it in the circumferential direction 9 around the container 2 along the original tearing direction 29, which is shown in FIGS. 6 a, b and 7.

When the tearing device 27 is moved in the tearing direction 29, the lid edge 6 begins to split in the tearing direction 29 in the area of the front edge 28 of the tearing device 27. At this extension of the front edge 28 or at the edge itself, a tear auxiliary line 30 is formed at the cover edge 6 as a material weakening line 31. It originally extends vertically upwards towards the opening edge 4. In the circumferential direction 9 and the tearing direction 29 perpendicular to the tearing auxiliary line 30, the edge tearing auxiliary line 32 extends. It is also made as a material weakening line.

By moving the tearing device 27 in the tearing direction 29, the bottom of the lid edge 6 is separated with the locking edge 10 as the locking element 7 along the tearing support line 32, FIG. 6. As shown in b and FIG. 7, the lid 1 can be separated from the container 2.

By separating the part corresponding to the lid edge for removing the lid 1, an indication can be obtained that the vessel 2 has already been used or has at least the first attempt to remove the lid from the vessel 2. have. This makes the lid tamper-evident so that such opening attempts cannot be made and can be detected by other users.

In FIG. 2, the detail code | symbol "X" of FIG. 1 is expanded and shown. The same parts are always denoted by the same reference numerals in all the drawings and some refer only to the relationship with one drawing.

The vessel 2 has an opening edge 4 widened outward on the top of the vessel wall 24. The cover part 5 of the cover 1 is located at the top thereof along with the bottom side 33. The opening edge region comprises an edge flange 11 which projects so that the lid part 5 is originally vertically upwards. Along the edge flange as well as the bottom side 33, a liquid tight plastic foil 34 is applied to the cover part 5. The lid portion 5 as well as the remaining portion of the lid is formed of one or more paper layers 38. Instead of one paper layer, in particular two paper layers joined by lamination may similarly be used for one or more cardboard layers and the like.

The lid edge 6 of the lid 1 is joined to the lid portion 5 via its edge flange 11. This cover edge 6 extends from the cover part 5 which is inclined downwardly outward.

The lid edge 6 comprises an upper edge end cross section 12. It originally has an inverted U-shape. The edge flange 11 is inserted into the corresponding U-opening 13 and fixed between the corresponding U-shaped leg portions.

The lid edge 6 comprises an upper edge portion 15, a middle edge portion 17, a lower edge portion 16 and a lower edge end 8, according to the upper edge end region 12. The upper and lower edge portions 15, 16 extend outwardly at an angle to the container 2. The middle edge portion 17 and the lower edge end portion 8 are inclined inclined outwardly and extend essentially vertically as shown in FIGS. 7 a to 7.

Corresponding edge portions 15, 17 and 8 of the lid edge 6 make approximately the step extension of the lid edge at its lower end 14.

The angle corresponding to the inclination of the upper edge portion 15, the middle edge portion 17, the lower edge 16 and the lower edge end 8 are shown in FIG. 3 as reference numerals 18, 19, 20 and 21.

Regarding the inclination angles 20, 21 of the upper and lower edge portions 15, 16, the angles 18, 19 of the middle edge portion 17 and the lower edge end portion 8, as well as those of FIGS. As shown, they are likely to be identical. In another embodiment, as shown in FIG. 3, the inclination angles 20, 21 are different and in particular the inclination angle 21 may be greater than the inclination angle 20.

The other tilt angles are each obtained from the corresponding angles between the vertical lines and the corresponding outer slopes of the corresponding edge portions.

In the area of the middle edge 17, an edge tearing auxiliary line 32 can be seen under the opening edge 4. It is aligned at a distance closer to the lower end 14 of the lid edge 6 than to the bottom side of the opening edge 4. Although part of the lid edge 6 is separated along the edge tearing support line 32, the lid 1 may still be located above the container and by its adjacency corresponding to the retention of the lid at the opening edge 4. It is ensured that it may be located inside the corresponding lid edge 6.

The lower edge end 8 consists essentially of two layers, the outer layer 22 and the inner layer 23, as shown in FIG. 3. This two-layer structure folds or bends the extension of the outer layer into the inner layer, thereby making the corresponding connection of both layers in the inner surface of the outer layer and at least in the region of the lower edge end 8. According to another part, the inner layer 23 is a continuation of the outer layer 22. The inner layer 23 extends to the lower edge portion 16 at an inclined angle 21 and correspondingly inclined upwardly inwards towards the lid portion 5. The inner layer extends along the lower edge portion 16, which is originally separated from the rest of the lid edge 6 towards the container wall 24, and forms a locking edge 10 as a locking element 7 next to it. The locking edge 10 extends around the entire container 2 in the circumferential direction 9.

The free end of the locking edge 10 is clamped below the opening edge 4 and is in close contact with the outside of the container wall 24 when the cover 1 is located in the container 2 or is installed adjacent to the container wall. Are arranged.

As shown in FIG. 3, on the outside of the container wall 14, the free end 25 adjacency of the locking edge on the cover is affected and positioned correspondingly above the cover 1 above the container 2. The free end 25 further bends the proximal portion of the vessel wall 24 towards the opening edge 4 to increase the tamper-evidence of the lid 1. Since the bending can be effected with this connection, the free end essentially leaves at least partly a gap 39 between the opening edge 4 and the container wall 24.

When the lid 1 is positioned above the container 2, the lid edge 6 is elastically radially outward, at least in the lower edge end region 8, the lower edge region 16 and the locking edge 10 as well as in the middle. As it extends to the edge region 17, it can pass along the opening end 4. As soon as the free end 25 touches the bottom side of the opening edge 4, the opening edge 4 and the container are particularly wide towards the container wall 24 due to the elasticity of the lid edge 6 and the locking edge 10. Pressure is applied into the gap opening 39 between the walls 24.

4 a to c show the various stages in which the corresponding lid 1 is placed in the container 2. At this stage, in particular the bending of the locking edge can be seen.

In the lid 1 according to FIGS. 4 a-c, the inclination angles of the upper and lower edge regions, as well as the middle and lower edge end regions, are the same as the original vertically extending middle and lower edge end regions, respectively. It can be seen that.

In addition, the structure of the cover 1 outside the area of the upper edge end region 12 can be seen in FIGS. This structure is formed of a plurality of recessed portions and high portions arranged in the circumferential direction 9, respectively.

In Fig. 3, two lids 2 are depicted stacked one above the other. In accordance with the corresponding details, references are made in other shapes as well as corresponding descriptions.

In FIG. 3, it can be seen in particular that the inner diameter 35 of the lower edge end region 8 is larger than the outer diameter 36 of the upper edge end region 12. As shown in FIG. 5, this stacks two covers 2 to allow at least the upper edge end region 12 of the lower cover to be inserted into the top cover along the bottom side of the locking edge 10. The locking edge 10 forms a lamination stop element 37 which stops on the upper edge end region 8 of the lower cover 2, from above it and from its original outside, according to at least FIG. 3.

In the embodiment according to FIG. 5, the covers, in which the lower edge end zones 8 and the upper edge end zones 12 extend essentially vertically, are arranged one by one so as to fit precisely and the lower covers at the lower end 14 of the upper cover. It is inserted into the top cover until it is almost adjacent to the upper edge zone 15.

In addition to FIG. 7, a and b of FIG. 6 show another embodiment of the tearing device 27. In b of FIG. 6, the detachable part of the lid edge 6 is already at least partly separated.

In this embodiment the tearing device 27 is similarly applied to FIG. 7 by being arranged by a portion of the lid edge 6 adjacent to the perforation line 30, rather than being formed as a separate part of the lid edge 6.

It should also be pointed out that with regard to the container cross section and equivalent to the corresponding shape of the lid, these may be round, oval, square, rectangular or similar shapes. In one aspect of the embodiment, a circular edge is advantageous.

It should also be pointed out that it is possible for the lid 1 to be positioned above the container 2 as well as due to the elasticity of the lid edge 6 and the corresponding locking edge 10. Usually, the container 2 is at least partially resilient in the opening edge 4 or in the area of the container wall 24 so that the container can also be elastically deformed when the lid is positioned.

In the embodiment according to FIGS. 4 a to 7, it should be noted that the corresponding inclination angle of the locking edge 10 is essentially the same as the inclination angles 20, 21 from the upper and lower inclined edge regions 15, 16. do. Here, the corresponding angles of inclination 20, 21 are also essentially the same, while the other edge regions 12, 17, 8 are not inclined and extend essentially vertically.

In the embodiment according to FIGS. 4 a-7, the covering part 5 essentially extends radially outwardly to the lower end of the upper edge zone 15 and ends approximately with the outer contour of the opening edge 4. There is another difference. This ends in the lid part 5 in an improved seal of the container 2. In addition, a small gap remains between the lid edge 6 and the opening edge 4, for example, as shown in FIG. 2 compared to c of FIG. 4.

In the embodiment of FIGS. 4 a to 7, it is shown in particular how the free end 25 of the locking edge 10 fits the gap opening 39 between the container wall and the opening edge 4.
