Description

The invention relates to an unauthorized exposure indicator cover for a container having a neckline extending around the upper neck of the container and, in particular, flanged, having a closure element substantially covering the upper neck of the container, and an edge extending substantially downward from the closure element to the container and having, at least in some positions, a latch that grips the lower neck edge and which can be completely separated from the lid, in particular with the lower end of its edge to remove the specified cover from the container.

Such a cover is known from US-A-5002198. The closure element of the lid is placed on the neck edge at the top, so that it closes the container neck. This element is connected to the edge of the lid extending vertically downward from it. The edge of the lid essentially tangentially adjoins butt to the curved or flanged edge of the container, and the latch protrudes from its end and ends under the neck edge, essentially capturing it from the bottom.

To disconnect the lid from the container, indicating unauthorized exposure or breaking, part of its edge, namely its lower end part, is separated together with the lock. Then the lid can be removed from the container. The complete separation of the end part of the edge with the latch from the rest of the lid, essentially, makes it possible to establish the fact of removing or at least preparing to remove the lid by another user, even if the lid is still in place or is again placed there. This allows you to establish the fact of any manipulation made over the lid, or any attempt to hack or open.

Thanks to such a lid, for example, opening the corresponding container, any effect on its contents or its partial removal with the subsequent closing of the container should not go unnoticed.

However, in the lid described above, it is possible to manipulate the latch by flexibly bending it outward in the radial direction so that it ceases to grab from the bottom of the container and the lid can be detached from the container without separating the end of the lower edge. In addition, the vertically extending edge of the lid can only be bent slightly elastically, so that in order to be able to install the lid on the container, the latch must have a correspondingly high elasticity, allowing it to be sufficiently bent radially outward in the region of the outwardly threaded edge. Such a relatively high intrinsic elasticity of the retainer allows appropriate manipulations to remove the cover, because due to the specified elasticity of the latch it is easier to bend it out with the subsequent possible removal of the lid from the container.

Therefore, the object of the invention is to improve the cover indicator of unauthorized exposure described above, so that it is structurally protected from possible manipulation of the latch to remove the cover with, on the other hand, its closing function.

This problem is solved in accordance with the characteristics of paragraph 1 of the claims.

The lid in accordance with the present invention is particularly characterized in that its edge is essentially inclined downward and outward from the closing element, and the latch is made in the form of a fixing edge extending in the circumferential direction of the lid, between the upper end part of the edge of this lid and its at the lower edge are at least one upper and one lower parts, which extend each obliquely and outward from the closure element and which are connected by a substantially vertical intermediate part.

When using a circular locking edge, there is no possibility of lateral insertion between the locking edge and the protruding oblique edge of the lid, for example, to bring the locking edge out of interaction with the lower part of the container edge. Due to the inlet of the lid edge inclined downward and outward, this edge can also be elastically bent when the lid is installed, so that both the fixing edge and the edge of the lid are elastically bent, and thus, the elastic interaction essentially takes place not only in the region retainer.

In addition, if the edge of the lid extends obliquely when trying to remove it from the container, the corresponding locking edge cannot be brought into a substantially vertical position without simultaneously manipulating the edge of the lid. On the contrary, due to the inclined placement of the edge of the lid, the corresponding locking edge is held with some inclination even when it is joined end-to-end with the edge of the lid from the inside, so that it is almost impossible to move relative to the neck edge to remove the lid without any visible traces.

Thus, the ability of the lid to indicate unauthorized exposure to it in accordance with the invention is increased without complicating the design. At the same time, due to the distribution of elastic forces along the edge of the lid and the fixing edge, it is easier to place the lid on the container without reducing the density of its fit or the ability to indicate unauthorized exposure.

According to the invention, the closure element of the lid may have various shapes. On the one hand, the geometric shape of the closure element along the neckline corresponds to the shape of the container neck. Alternatively, on the outside of the neckline, the closure element may, for example, be bent, bent, or deformed in any way in the direction of the container’s internal cavity, or may be deformed accordingly from the container. A simple lid closure element, which is also easy to manufacture, can be substantially flat. Being placed on the edge of the container, it completely closes its neck to protect it from external influences and at the same time seal its contents.

To facilitate, for example, work with the lid and to remove it from the container, the closure element may have an edge fold extending in the circumferential direction and directed substantially vertically upward from it.

The edge of the lid can be directly attached to the specified flat closing element or edge fold.

In a simple embodiment of the invention, the edge of the lid for direct attachment to the edge fold has, for example, an upper end part made essentially in the form of an inverted letter U, into the opening of which the said fold is inserted and fixed there. The depth of the U-shaped opening may substantially correspond to the vertical length of the edge fold. Thus, it is clamped on both sides by the corresponding U-shaped extensions of the upper end part of the specified edge and can, for example, be attached to them by gluing, hot sealing or other methods.

The specified edge of the lid can evenly extend from the upper edge of the lid to the bottom with a slope down and out. However, to facilitate installation of the cover while creating a seal between its edge and the neckline, at least one upper part and one lower part can be located between the upper end part of the edge and its lower edge, which protrude obliquely each outward from the closure element and which then connected by a substantially vertical intermediate part. The latter may be particularly designed to abut against the neck edge so that the lid itself can be securely placed on the container and held there even after the end portion of the edge has been completely removed.

Such a substantially stepwise inclined inlet of the edge of the lid gives it a winning appearance, and the lid itself becomes more convenient to grip and mount on the container.

In this regard, the aforementioned lower end part of the edge of the lid can be made so that it extends essentially vertically between the lower part of this edge and its lower end. As a result of this, the gap formed between the lower end part of the edge and the container wall is inferior to the gap that can be formed by the indicated part deflected outward, which leads to a narrowing of the corresponding space for possible manipulations.

Essentially, the vertical intermediate and lower end parts of the edge can be given a certain inclination to the outside, the angle of which is inferior to the angle of inclination of the upper and lower parts.

To optimize the appearance and production technology of the lid in a preferred embodiment of the invention, the angles of inclination of the upper and lower parts and / or the intermediate and lower terminal parts are equal.

Stabilization of the lower end part, as well as the fixing edge, can be obtained by performing at least the specified part of two layers, internal and external. As a result of this, the lower end part has increased rigidity, which, on the one hand, complicates the possible manipulations above it when removing the cover, and, on the other hand, strengthens the fixing edge.

In a simple embodiment of the invention, the locking edge can be made as a continuation of the inner layer. In this case, it is a simple continuation of the inner layer in the direction of the container to capture the corresponding neckline from the bottom.

The locking edge may be a direct continuation of the inner layer in the region of the lower end portion of the edge. However, the inner layer can also extend at least partially towards the lower part of the edge, and the corresponding angle of inclination of this part can serve to deflect the inner layer and, accordingly, the fixing edge in the direction of the container wall.

In this case, the angle of inclination of the lower part of the edge may coincide with the angle of inclination of the fixing edge, so that when the lid is placed on the container and captures the neckline from below, the locking edge extends obliquely upward towards the container wall.

It is indicated above that in accordance with the invention, the elastic forces arising when the edge of the lid and the fixing edge are folded when the lid is placed on the container are distributed over these edges. In a preferred embodiment of the invention, when the lid is placed on the container, the locking edge elastically bends radially outward. This applies to at least a part of the fixing edge protruding respectively from the lower part or the lower end part.

In order to minimize the space between the free edge of the fixing edge and the container wall and at the same time make it difficult to manipulate the fixing edge, the latter can have a cutting edge on its free edge, running essentially parallel to the container wall when the lid is placed on the container. The end edge of the slice may also abut against the container wall when placing the lid on the container. The corresponding position of the end edge of the shear complicates the stretching and passage of the free edge of the locking edge through the neck edge.

To open the cover, it is necessary to completely separate the lower end part and the locking edge from the rest of the cover. For the convenience of this action, a tear-off device may protrude from the edge of the lid. You can place several of these devices. The tear-off device can, for example, protrude almost perpendicularly from the edge of the lid, so that it can be easily grabbed on the side of the specified edge, and then used to separate the corresponding part of the lid. The tear-off device may also be a continuation of the edge of the lid at its lower edge.

In order to make the tear-off with the aid of said device in the lower end part safe and controllable, a substantially vertical auxiliary tearing aid may be formed in the region of this device and in particular in its frontal edge in the tear-off direction in the edge of the lid. If then the tear-off device is captured and moved in the tear-off direction, then the lid edge is torn off first along the vertical auxiliary device, and subsequently, the corresponding part of the lid edge is further separated, essentially in the circumferential direction.

Auxiliary bursting device may have various designs. In general, it is made in the form of a line weakening the material. Such a line may be thinning of the material, perforation, etc.

To further remove the corresponding part of the edge of the lid in a simple and manageable way, without affecting the appearance of the lid, essentially perpendicular to the auxiliary tensile device in the edge of the cover, an edge auxiliary tear-off device can be formed at some distance from its lower edge and extend in the circumferential direction. The edge tear-off accessory intersects the auxiliary tear-off device in the perpendicular direction, so that when the tear-off device is moved in the separation direction after the destruction of the auxiliary tear-off device, the corresponding part of the lid edge is further separated along the edge auxiliary tear-off device.

The edge tear-off aid may be in the form of a material-weakening line, similar to the tear-off assist.

In this regard, in order to ensure that the lid can be placed on the container and held with its edge on the neck edge and after separating the corresponding part of the lid edge, the edge tear-off device can be placed so that when the lid is mounted on the container, it is closer to the lower edge the edges of the lid, not the neck edge. Moreover, after tearing off the corresponding part of the edge of the lid, a significant part of it still remains and essentially passes along the neckline down, so that it is possible to replace the lid and keep it securely held on the container.

A variety of materials are available for the lid. The cover may be fully or partially made of plastic. The material, in particular the material of the closure element, may be at least partially transparent or translucent. Thus, the contents of the container becomes visible. The lid can easily be manufactured and recycled, which is explained by the fact that the lid is essentially made of one or more paper layers. In addition, printed text with advertisements or indicating the contents of the container is easily applied to the paper layer.

When the lid is installed, the lid closure element must not only protect the contents of the container from undesirable substances penetrating into it, but also protect against leakage of the container contents at least in the region of the closure element, therefore, a liquid-tight plastic film can be applied to the back of the lid. If, for example, there is liquid in the container, such a plastic film further prevents the absorption of liquid into the paper layer of the lid and a corresponding change in the appearance of the lid.

It is also possible that the cover, or one of its parts, consists not only of one paper layer, but has interconnected and, in particular, laminated paper layers. It has already been pointed out that at least in the region of the extremity of the lower edge, its structure consists of two layers, of which the inner layer forms a fixing edge. Here, the corresponding layer may also be paper.

For convenient storage of the lids during their production or in the process of closing the containers, the lid can be stacked and unstacked.

The possibility of stacking the lid unstacking can be achieved when, for example, the inner diameter of the edge of the lid, at least from the side of its lower edge, is larger than the internal diameter of the upper end part of this edge. To improve the stackability of the covers, an appropriate ratio between the inner diameter and the outer diameter can be established for the lower end part of the edge, possibly up to the region of the lower part of the edge.

In order to prevent the covers from getting stuck, being inserted one into the other, which may make it difficult to stack them, for example, in automatic mode, a locking edge can be used as a stopper when stacking, abutting the upper end part of the edge from the outside and, in features on top.

figa is a side view with a partial lateral section of a variant of the cover made in accordance with the invention, with a tear-off device;

Fig.6b illustrates the lid shown in Fig.6A, in a partially torn and open state, and

Fig. 7 illustrates yet another embodiment of a closure made in accordance with the invention with a tear-off device of a different shape.

figure 1 is a side view with a partial longitudinal section of a variant of the cover 1, made in accordance with the invention, on a bowl-shaped container 2.

The container 2 has an upper neck 3 (see also other drawings) surrounded by a flanged neck edge 4. A bottom is inserted from the lower edge of the container 2, which is held therein with a seal, essentially the end of the container wall 24, curved inward.

The lid 1 is placed on top of the container 2 and contains a substantially flat closing element 5 lying on the edge 4 and sealing it on top. The lid 1 also has an edge 6 protruding downward and outward from the element 5. The edge 6 extends around the container along the edge 4 in the circumferential direction 9. At the edge 6, namely at its lower edge 14 (see also figure 2) there is a tear-off device 27. It can be captured by the user and moved along the tear-off direction 29 (Fig. 1), essentially in the 9-direction around the container 2 (see also Figs. 6a, 6b and 7).

If the device 27 is moved in the direction 29, then the edge 6 will begin to collapse in this direction in the region of the front edge 28 of the device 27. In the edge 6, as an extension of the edge 28 or a separate edge, an auxiliary tensile device 30 is formed in the form of a material-weakening line 31. It passes, essentially vertically upward to the edge 4. Perpendicular to the device 30 in the direction 9, as well as in the direction 29 there is an auxiliary edge tear-off device 32. It is also made in the form of a material weakening NII.

By moving the device 27 in the direction 29, the lower part of the edge 6 is separated along the fixture 32 together with the locking edge 10 acting as the retainer 7, so that the lid 1 can be removed from the container 2 (see also Fig.6b and 7).

The separation of the corresponding part of the lid edge to remove the lid 1 is an indication of the fact of using the container 2 with the lid 1, or at least attempts to remove it from it. This fact gives the cover the function of an indicator of unauthorized exposure, as after trying to open it, it cannot be returned to its original state, and such an attempt can also be detected by another user.

In Fig. 2, part X of Fig. 1 is shown on an enlarged scale. The same reference numbers in all the drawings always have the same designations and are only partially mentioned in connection with one drawing.

The edge 4 of the container 2 is flanged outward on the upper edge of the wall 24. The element 5 of the lid 1 with its bottom side 33 is placed on the upper side of the wall 24. In the region of the edge of this neck element 5 has an edge fold 11, essentially protruding vertically upward. A plastic film 34 is impervious to the fluid along the side 33 and along the side 33. The element 5, as well as the rest of the lid 1, can be formed from one or more paper layers 38. Instead of one paper layer, two such layers can be used. especially bonded as a laminate, respectively one or more layers of cardboard or the like.

The edge 6 of the lid 1 is connected to the element 5 by means of a fold 11. This edge 6 extends from the element 5 at an inclination downward and outward.

The edge 6 has an upper end part 12, which is made in the form of an inverted letter U. A fold 11 is inserted into the corresponding U-shaped opening 13, which is fixed here with the corresponding U-shaped extensions.

The edge 6 has an upper end part 12, an upper part 15, an intermediate part 17, a lower part 16 and a lower end part 8. Parts 15, 16 protrude outward at an angle to the container 2. Part 17 and part 8 protrude outward at a smaller angle and can also protrude essentially vertically (see figa - 7).

Parts 15, 17, 16 and 8 of the edge 6 give it an almost incremental expansion in the direction of the edge 14.

The corresponding angles of inclination of part 15, part 17, part 16 and part 8 are illustrated in FIG. 3 (see keys 18, 19, 20 and 21).

The angles 20 and 21 of parts 15 and 16 may be equal (see also Figs. 4a - 7), as well as the angles 18 and 19 of parts 17 and 8. In another embodiment of the invention (see also Fig. 3), angles 20 and 21 are unequal , and in particular, the angle 21 may be larger than the angle 20.

Each of these angles is formed by a vertical and a corresponding edge part protruding obliquely outward.

In the region of the part 17 below the edge 4, a fixture 32 can be observed, the distance from which to the lower edge 14 of the edge 6 is inferior to the distance from the fixture 32 to the bottom of the edge 4. As a result, even with a partial separation of the edge 6 along the fixture 32, the cover 1 can continue to be on container 2 and, accordingly, it can be held on the edge 4 adjacent to the inner side of the edge 6.

Part 8 is essentially made up of two layers, an outer layer 22 and an inner layer 23 (see also FIG. 3). This two-layer structure is obtained by bending inwardly the extension of the outer layer to obtain an inner layer and correspondingly connecting both layers at least in the region of part 8. In other cases, layer 23 is a continuation of layer 22. Layer 23 extends to part 16 at an angle of 21 and accordingly extends inward and upward inclined to the element 5. The inner layer essentially follows the part 16 separately from the rest of the edge 6 and is directed to the wall 24, so that it forms the edge 10, functioning as a retainer 7. The edge 10 runs around the entire eynera 2 in the direction 9.

The free edge of the edge 10 captures the bottom edge 4 and when placing the lid 1 on the container 2 is placed next to the outer side of the wall 24 or, if necessary, end-to-end with the container wall.

The free edge 25 (see FIG. 3) of the edge 10 can adjoin the outer side of the wall 24, so that after the lid 1 is properly placed on the container 2, it continues to deviate relative to the edge 4 due to its adjacency to the wall 24, which increases the ability of the lid 1 to be indicated unauthorized exposure. In this regard, such a deviation can lead, at least, to a partial interaction of the edge 25 with a gap 39 formed between the edge 4 and the wall 24.

When the lid 1 is placed on the container 2, the edge 6 can be elastically radially expanded outward by at least its parts 8, 16 and 17, as well as by the edge 10, so that the latter can extend along edge 4. When edge 25 reaches the lower side of edge 4 due to the elasticity of the edge 6 and edge 10, it is pressed against the wall 24, namely, in the gap 39 between the flanged edge 4 and the wall 24.

Figures 4a-4c illustrate the various steps of placing the corresponding lid 1 on the container 2. At these stages, it is possible to track in particular the deflection of the edge 10.

On figa-4C, you can especially see that on the cover 1, the angles of inclination of the upper and lower edge parts, as well as the intermediate edge part and the lower end edge part, respectively, are the same, with the last two parts essentially extending vertically.

In addition, FIGS. 4a-4c show in particular the structure of the outer side of the lid 1 in the region of part 12. This structure is formed by recesses and elevations, respectively located in direction 9.

Figure 3 illustrates two stacked lids 1 with the placement of one above the other. When describing the relevant details, references are made to other drawings and related descriptions.

Figure 3, in particular, shows that the inner diameter 35 of part 8 exceeds the outer diameter 36 of part 12. This allows you to stack two covers 2 at least so that part 12 of the lower cover is inserted into the upper cover on the bottom side of its edge 10 ( see also FIG. 5). The edge 10 forms, at least in the embodiment of the invention according to FIG. 3, a stopper 37, when stacked, resting on top and, essentially, externally, on part 12 of the lower cover 1.

In the embodiment of the invention in accordance with FIG. 5, part 8 and part 12 are essentially vertically arranged so that the stacked covers are precisely placed one on top of the other, with the bottom cover inserted into the top cover approximately until the edge 14 of the top cover is joined to part 15.

6a and 6b, as well as in FIG. 7, other embodiments of the device 27 are illustrated. In FIG. 6b, the detachable portion of the edge 6 is already at least partially separated.

The same applies to the embodiment of the device 27 illustrated in FIG. 7, which is essentially not formed as a separate part of the edge 6, but is a part adjacent to the line 30.

The cross sections of the container and their corresponding lids can be round, oval, elliptical, square, rectangular, etc. In embodiments of the invention, rounded edges are preferably used with ribs.

In addition, the placement of the lid 1 on the container 2 can be achieved not only due to the elasticity of the edge 6 and, respectively, of the edge 10. Typically, the container 2 itself is at least partially elastic in the region of the edge 4 or the wall 24, so that when the lid is placed on it can also be elastically deformed.

In the embodiments of the invention in accordance with FIGS. 4a-7, the corresponding angle of inclination of the edge 10 is essentially equal to the angle 20, 21, formed respectively by parts 15, 16. The corresponding angles 20, 21 are also essentially equal, because other parts 12, 17, 8 are not inclined and essentially extend vertically.

The embodiments of FIGS. 4a-7 have another difference in that the element 5 extends substantially radially and outward to the lower edge of the part 15 and approximately terminates at the outer contour of the edge 4, thereby the element 5 densifies the container better 2. In addition, in this case, the gap between the edge 6 and the edge 4 is smaller (for example, see Fig. 2 in comparison with Fig. 4c).

In embodiments of the invention in accordance with figa-7 in particular shows the interaction of the edge 25 of the edge 10 with a gap 39 between the wall 24 and the edge 4.
