Description

Description of the invention

The invention relates to a lid for a container, the manipulation of which cannot be concealed, the container 2 having an opening with a rim around the top opening of the container and in particular contacting a flange of a part of the lid, which essentially closes the top opening of the container, and the edge of the lid passes, essentially , down from this part of the lid to the container and has, at least in some positions, a locking member that engages below the edge of the opening and can be separated from the lid together with the lower end of the edge of the lid to remove the lid from the container. 70 Such a cover is described in (Ш5-А-5002198). The corresponding part of the cover is placed on the edge of the hole from above and this hole is closed. This part of the cover is connected to the edge of the cover, directed vertically downwards. The edge of the cover is essentially tangentially adjacent to the closed or flanged edge of the container, and the locking element protrudes from its free end and ends below the edge of the opening, engaging below this edge.

For covert or destructive removal of the lid from the container, this part of the edge of the lid and in particular the part 72 of the lower end of the edge is separated together with the locking element, after which the lid can be removed from the container.

The separation of the end of the rim, together with the locking element, from the rest of the lid ensures that even if the lid is left in place or replaced, it will be easy to tell if the lid has been removed or prepared to do so by another user. This allows detection of any tampering or attempts to break or open the container. Such a lid can, for example, prevent the opening of the container, manipulation of the contents or removal of part of the contents of the container with subsequent closure and detect such manipulations from the outside without opening the container.

The object of the invention is a structurally simple improvement of the lid, the manipulation of which cannot be hidden, of the above type, which protects against possible manipulations with the locking element for the purpose of removing the lid and ensures further use of the lid to close the container. with

This problem is solved by the means defined in clause 1 of the Formula of the invention. heh)

The invention, in particular, is characterized by the fact that the extension of the edge of the lid is directed, in fact, downwards and outwards from the part of the lid, and the locking element is designed as an engaging edge passing in the direction around the lid.

The use of a surrounding engaging edge eliminates the possibility of side access between the engaging edge and the inclined extension of the lid edge, for example, to release the engaging edge from engagement below the edge of the container. Due to the downward and outward deflection of the lid edge extension, this edge can be resiliently deflected when the lid is installed in place, causing the engaging edge and the lid edge to be resiliently deflected when the lid is installed, with no resilience near the locking element. --

Furthermore, with an inclined extension of the lid edge, the corresponding engaging edge cannot be brought into an essentially vertical position without simultaneously manipulating the lid edge for possible removal of the lid.

Out of the container. Instead, the bevel of the lid edge holds the corresponding engaging edge in a certain inclined position, even though it abuts the lid edge from the inside, making it almost impossible to slide it past the edge of the lid removal opening without visible consequences.

According to the invention, this makes it easier to detect tampering with the lid. At the same time, the installation of the lid on the container is ensured by the distribution of elasticity on the edge of the lid and the engaging edge without reducing the ability to detect manipulations and the tightness of the lid. According to the invention, part of the cover can have any shape. On the one hand, the geometric shape of this part lying along the edge of the opening essentially corresponds to the shape of the opening of the container. On the other hand, from the outside edge of the opening, the part of the lid can be bent, warped or otherwise deformed towards the inside of the container, or correspondingly deformed towards the outside of the container. A simple part of the lid, which is easy to manufacture, can be essentially flat. In this case, it rests on the edge of the container and closes the opening of the container, protecting against external interference and tightly closing the contents of the container. c To facilitate handling of the lid when removing it from the container, a portion of the lid may have a flange on the edge which passes in a circumferential direction and, in fact, vertically protrudes upwards. - The edge of the lid can be directly attached to the flat part or to the flange of the lid. Fig. 20 In a simple example of a direct connection with a cover flange, the cover edge has the upper end part of the edge in the form of an inverted letter OO, and the edge flange is inserted into the gap Ш and fixed in it. The depth of the U gap can correspond to the vertical length of the edge flange. Thus, the flange of the edge is covered on both sides by the corresponding sides О of the upper edge and can be fastened to them, for example, by gluing, heat welding or in some other way. 29 The edge of the lid may extend evenly from the upper end to the lower end, deflected downward and outward. However, in order to facilitate or improve the installation and sealing of the lid edge, the edge between the upper end portion of the edge and the lower end may have at least one upper and one lower edge portion, each of which deviates outwardly from the lid portion and connects with the other substantially , the vertical intermediate part of the edge. This intermediate part of the edge can serve, in particular, to adhere to the edge 60 of the opening from the outside, thanks to which the lid can be securely installed on the container and held on it even when the end part of the edge is completely detached.

This essentially stepped angled extension of the lid edge creates an optically attractive lid appearance, and the lid itself can be easily gripped and placed on the container.

The above-mentioned lower end part of the edge in this connection can essentially vertically extend between the bottom edge part and the lower end of the cover edge. Thanks to this, the gap between the lower end part of the edge and the wall of the container is smaller compared to the variant of the inclined extension of the lower end part of the edge and leaves less space for possible manipulations.

This essentially vertical extension of the intermediate part of the edge and the lower end part of the edge can also be replaced by a somewhat inclined extension of these parts, which extend outwards with a smaller angle of inclination than the upper and lower parts of the edges.

For the appearance and manufacture of the lid, it is advisable that the angles of inclination of the upper and lower parts of the edge and/or the intermediate and lower end parts of the edge are the same.

Stabilization of the end part of the lower edge and, therefore, stabilization of the leading edge require 7/0 Manufacturing of at least the lower end part of the edge in two layers - outer and inner. This increases the rigidity of the lower end part of the edge and, on the one hand, complicates the actions of removing the cover, but, on the other hand, strengthens the engaging edge.

In a simple embodiment, the engaging edge can be an extension of the inner layer. In this case, it simply extends as an extension of the inner layer to the clutch container below the corresponding 7/5 edge of the opening.

The engaging edge may extend directly as an extension of the inner layer near the lower end of the edge. In another embodiment, this inner layer extends at least partially to a part of the lower edge so that, due to the proper angle of inclination of this part of the edge, it serves to deflect the inner layer and thus the engaging edge towards the wall of the container.

In this case, the angle of inclination of the part of the lower edge may continue in the engaging edge, and therefore the latter continues with an inclination upwards to the wall of the container when the lid is installed, and engages below the edge of the opening.

As already noted, according to the invention, the elasticity required to deflect the lid edge and the engaging edge and, therefore, to install the lid on the container, is distributed between the lid edge and the engaging edge. high school

Only when the lid is mounted on the container is it advantageous for the engaging edge to have the ability to elastically deflect outward. This applies to at least the portion of the engaging edge that projects from the lower edge portion (8) or the lower end edge portion, respectively.

In order for the gap between the free end of the hooking edge and the container wall to be as small as possible to complicate manipulations with the hooking edge, this edge can have a terminal cutting edge on its free end, which extends parallel to the wall and can be directly adjacent to the container wall when the cover is installed. The corresponding extension of the end edge of the cut makes it difficult to extend and pass the free io) end of the hook edge to the edge of the hole. "-

To open the cover, it is necessary to completely separate the lower end part of the edge and the engaging edge from the rest of the cover. To simplify this operation, a rupture device can protrude from the edge of the lid. There can be M several such devices. This device may, for example, project approximately perpendicularly from the edge of the lid in such a way that it can be easily grasped from the side of the edge of the lid and then used to separate the corresponding part of the lid. The tear device may also extend as an extension of the edge of the cap at its lower end.

In order to ensure a controlled and safe tear in the tender end of the edge, a bursting device near this device and, in particular, on the front face in the direction of the tear, can be formed, - in essence, a vertical, auxiliary tear in the edge of the lid. If the tear device is grasped and moved in the direction of the tear, the lid edge is first torn along the auxiliary tear, followed by subsequent separation of the corresponding portion of the lid edge in an essentially circumferential direction.

Such an auxiliary tear can have a different form. In general, its purpose is to create a line of weakening of the material, which can be provided by its thinning, perforation, etc. To ensure further controlled and safe separation of the corresponding part of the lid edge without damaging the appearance of the lid, after removal of this part, an auxiliary tear-off means may be formed, which extends in a circumferential direction, essentially perpendicular to the auxiliary tear, in - the edge of the lid at some distance from its lower end. This auxiliary means intersects the perpendicular auxiliary tear, due to which, when advancing the tearing device in the direction of the tear after tearing 1 auxiliary tear, further separation of the corresponding part of the edge of the lid occurs along this layer of the auxiliary tearing means.

The edge tear-off aid can be made as a material weakening line similar to the tear-off aid.

In this regard, in order to make it possible, even with the separated part of the lid edge, to place the lid on the container and secure the lid with its edge on the opening edge, the edge separation aid may (F) be arranged closer to the lower end of the lid edge than to the opening edge, when the cover is installed.

Thanks to this, after tearing off the corresponding part, a part of the edge of the lid remains, sufficient to extend over the edge of the opening downwards and to enable the replacement of the lid and the reliable fastening of the lid to the container.

The cover can be made of various materials, in particular, be made entirely or partially of plastic. It can be at least partially transparent or translucent. This applies, in particular, to the part of the lid. The contents of the container are visible. To facilitate manufacturing and recycling, the lid can be made from one or more layers of paper. Advertising text 65 or information about the contents of the container may be printed on the paper layer.

Since, when the lid is installed, the lid portion must protect the contents of the container from ingress of unwanted substances as well as leakage from the container, at least in the bottom area of the lid portion, a liquid-tight plastic foil may be applied. Such a foil, in addition, repels the percolation of the liquid contained in the container to the paper layer of the lid and, in particular, the part of the lid, and prevents the deterioration of the external

I look

The cover or one of its parts can consist not only of a layer of paper, but of interconnected and, in particular, laminated layers of paper. As already noted, at least in the area of the lower end part of the edge, two layers are used, and the lower layer forms the engaging edge.

To facilitate storage of the lid for closing the container or after its manufacture, it can be 7/0 Made stackable or non-stackable.

This fit can be achieved by making the inner diameter of the lid edge at least at the lower end larger than the outer diameter of the upper end of the edge. A suitable ratio between the inner and outer diameters can also be provided for the lower end part of the edge and for the lower part of the lower edge to achieve the above suitability.

In order to prevent the lids from sticking together in a stack when it is assembled, for example by an automatic machine, the engaging edge can be made as a limiting element of the stack, which adjoins the upper end part of the edge from the outside and, in particular, from above, when the lids are stacked.

Next, one of the embodiments of the invention is considered with reference to the drawings, in which:

Fig. 7 - another embodiment of the lid according to the invention with a rupture device of a different shape. Fig. 1 contains a partial cross-sectional side view of an embodiment of the lid 1 according to the invention on a cup-shaped container. io)

The container 2 has an upper opening 3 surrounded by an edge 6 flanged outward. At the lower end, the bottom "- part is inserted into the container 2 and is held there, tightly closing the end part of the wall 24 of the container, bent inwards, in the usual way. with

The cover 1 rests on the container 2. The cover has, in fact, a flat covering part 5, which lies on the edge 4 of the opening, tightly closing it from above. The cover 1 also has a cover edge 6 which extends from the cover part 5 with a downward and outward deflection. The edge 6 of the cover passes along the form 4 of the opening in the direction 9 around the container. On the edge b of the cover, in particular, at the lower end 14 (see also Fig. 2), a tearing device 27 is provided. The user can grasp it and push it in the direction 29 of tearing, in fact, in a circumferential direction " 9 around the container 2 (see Fig. .ba, 66, 7). z c If you advance the tearing device 27 in the direction of tearing 29, the edge 6 of the cover begins to tear in the area of the front edge 29 of the tearing device 27 in the direction 29 of tearing. In the continuation of this front edge 28 or the edge itself, an auxiliary tear 30 is formed in the form of a line 31 of material weakening in the edge b of the cover. It extends, in fact, vertically upwards to the edge of the 4 hole. Perpendicular to the auxiliary tear ZO in the circumferential direction 9 and in the direction 29 of tearing, the auxiliary means 32 of the edge separation runs, made as a line of weakening of the material.

When advancing the tearing device 27 in the direction 29 of tearing, the lower part of the edge b of the lid ko is separated along the line of the auxiliary means 32 of the edge separation together with the engaging edge of the opening 10 as a closing element 7, due to which the lid 1 can be removed from the container 2 (see Fig. ba, 7).

The removal of the corresponding part of the edge 6 of the lid to remove the lid 1 is an indicator that the container 2 with the lid 71 has already been in use, or that at least a first attempt has been made to remove the lid 1 from the container 2. This makes tampering with the lid obvious, since the consequences opening attempts are irreversible.

Figure 2 shows an enlarged view of detail "X" of Figure 1 (with designations common to all Figures).

The container 2 has an opening edge 4 flanged outwardly at the upper end of the wall 24 of the container. Part 5 of the cover 1 rests on its upper part with the bottom part 33. In the area of this edge of the opening, part 5 of the cover has

GF) flange 11 of the edge, which extends, in fact, vertically upwards. Along this flange 11, as well as the bottom

F of part 33 on part 5 of the cover is superimposed a liquid-proof plastic foil 34. In another version, part 5 of the cover and the rest of the cover 1 can be made of one or more layers 38 of paper. Instead of one layer, two layers of paper can also be used, in particular, connected by lamination, or, accordingly, one or more layers of cardboard, etc.

The edge 6 of the cover 1 is connected to the part 5 of the cover by the flange 11 of the edge. This edge 6 of the cover extends from part 5 of the edge with an inclination downward and outward.

The edge 6 of the cover has the upper end part of the edge 12 in the shape of an inverted letter O. The flange 11 of the edge 65 is located in the gap 13 of the letter | and secured between the respective parties.

The edge 6 of the cover has, in addition to the upper end part 12 of the edge, the upper part of the edge 15, an intermediate part

17 edges, the lower part of 16 edges and the lower end part of 8 edges. The upper and lower parts 15, 16 of the edge extend outward with an inclination relative to the container 2. The intermediate part 17 of the edge and the lower end part 8 of the edge have a smaller inclination outward and can extend essentially vertically (Fig. 7, 8).

The corresponding parts 15, 17, 16, 8 of the edge b of the cover form a relatively stepped extension of the lower end 14 of the edge of the cover.

Corresponding angles of inclination of the upper part of the 15 edge, the intermediate part of the 17 edge, the lower part of the 16 edge

The edges of the lower end part 8 are shown in Fig. 3 (and marked 18, 19, 20, 21).

The angles 20, 21 of the inclination of the upper and lower parts 15, 16 of the edge can be the same (Fig. 4a - 7), as well as the angles 7/0. 18, 19 of the intermediate part 17 and the lower end part 8 of the edge. In another embodiment (Fig. 3), the angles 20, 21 of the inclination are different, in particular, the angle 21 can be greater than the angle 20.

Different angles of inclination are determined by the corresponding angle between the vertical and the corresponding outward deviation of the corresponding part of the edge.

Near the intermediate part 17 of the edge under the edge 4 of the opening there is an auxiliary means 32 of the separation of the edge. 75. It is located closer to the lower end of the edge 14 of the cover than to the bottom of the edge 4 of the hole. Due to this, even if part of the lid edge 6 is separated along the line of the edge separation aid 32, the lid 1 can be installed on the container 2 and, accordingly, the lid can be held on the edge 4 of the opening by abutting the corresponding inner side of the lid edge 6.

The lower end bottom part 8 of the edge is made of two layers - the outer layer 22 and the inner layer 23 (Fig. 3). Such construction is due to the folding or bending of the continuation of the outer layer as the inner part of the outer layer and the corresponding connection of both layers at least in the area of the final lower part of the 8 edge. The inner layer 23 is a continuation of the outer layer 22. The inner layer 23 continues to the lower part 16 of the edge at the angle of inclination 21 and extends inwards and upwards to the part 5 of the cover. The inner layer from the lower part 16 of the edge separately from the rest of the edge b of the lid extends to the sov wall 24 of the container and forms a catch edge 10 on the locking element 7. The catch edge 10 covers the entire container around the circumference. at

The free end of the engaging edge 10 engages below the edge 4 of the opening and passes near the outer side of the wall 24 of the container when the lid 1 is installed on the container 2, or abuts the wall of the container.

Adhesion of the free end 25 (Fig. 3) of the hooking edge 10 to the outer side of the wall 24 of the container can be realized in such a way that after the appropriate application of the cover 1 on the container 2, the free end 25 is deflected through contact with the wall 24 of the container to the edge 4 of the opening for in order to make the handling of the lid 1 more visible io) This deviation can be made such that the free end at least partially enters the gap 39 between the edge 4 of the opening and the wall 24 of the container.

When the cover 1 rests on the container 2, the edge b of the cover can elastically deflect radially outward c z5 at least together with the lower end part 8 of the edge, the lower part 16 of the edge and the intermediate part c o 17, as well as the engaging edge 10, which as a result can pass along the edge 4 holes. As soon as the free end 25 reaches the bottom side of the edge 4 of the opening, it is pressed against the wall 24 of the container and, in particular, enters the gap 39 between the flanged edge 4 of the opening and the wall 25 of the container due to the elasticity of the edge 6 of the cover and the engaging edge 10.

Fig. 4a - 4c illustrate different stages of installation of the corresponding cover 1 on the container 2. On them, you can see from c different deviations of the hooking edge.

In Fig. 4a - 4c, in cover 1, the angles of inclination of the upper and lower parts of the edge, as well as the intermediate part and the lower end part of the edge are the same, and the intermediate part and the lower end part of the edge extend vertically.

In Fig. 4a - 4c, you can see the structure of the outer side of the cover 1 in the area of the upper end part 12 of the edge. This structure is formed by a set of depressions and protrusions formed in the circumferential direction 9.

Figure 3 shows two covers 2, stacked one on top of the other. The designation and description correspond to those given in other Figs. - In particular, in Fig. 3 it can be seen that the inner diameter 35 of the lower end part 8 of the edge is larger than the outer diameter 36 of the upper end part 12 of the edge. This allows you to stack two covers 2 on top of each other 1 in such a way that the upper end part 12 of the edge of the lower cover enters the upper cover to the bottom side sl of the engaging edge 10 (Fig. 5). The engaging edge 10 forms (at least in the embodiment of Fig. 3) a limiting element 37 of the stack, which rests on the lower end part 8 of the edge of the lower cover 2 from above and from the outside.

In the embodiment of Fig. 5, the lower end part 8 and the upper end part 12 of the edge extend essentially Vertically, and therefore the stacked covers exactly fit one another and the lower cover enters the upper until it almost rests on the lower end 14 of the upper cover with the upper part of 15 edges.

GF) Fig.ba, 65, 7 illustrate another embodiment of the breaking device 27. In Fig.bb, the separating part of the edge 6t of the cover is shown at least partially separated.

In the embodiment in Fig. 7, the breaking device 27 is not a separate part of the formwork b of the cover, but is a part of the formwork 6b of the cover, adjacent to the line ZO of the break.

The cross-sectional shape of the container and, accordingly, the lid can be round, oval, elliptical, square, rectangular, etc. Forms with corners have rounded edges.

It should be noted that the installation of the cover 1 on the container 2 is made possible not only by the elasticity of the edge 6 of the cover and, accordingly, the engaging edge 10. Usually, the container 2 is at least partially elastic in the area of the edge 65 4 of the opening or the wall 24 and can undergo elastic information during the installation of the cover.

It should be noted that in the embodiments illustrated in Fig. 4a - 7, the angle of inclination of the engaging edge 10 is essentially the same as the angle 20, 21 of the inclination of the upper and lower inclined parts 15, 16 of the edge. Here, the corners 20, 21 are essentially the same, and the other parts 12, 17, 8 of the edge are not inclined and extend essentially vertically.

In the embodiments illustrated in Fig. 4a-7, part 5 of the cover extends, in fact, to the lower end of the upper part 15 of the edge radially outward and ends approximately at the outer contour of the edge 4 of the opening. This improves the tightness of closing the container 2 with part 5 of the lid. In addition, the gap between the edge 6 of the cover and the edge 4 of the opening (Fig. 2) is reduced compared to Fig. 4c.

In the embodiments illustrated in Fig. 4a-7, it is possible to see how the free end 25 of the engaging edge 10 enters the gap 39 between the container wall and the edge 4 of the opening.
