Abstract

On a traditional pivoting-hinged lid (1) comprised of a lower element (2) and a cap (3), in one of these elements, a recessed handle is provided (32). The recessed handle (32) is covered by an integrity warranty (4). The integrity warranty (4) is configured as a plate (44), and theoretical breaking hasps (5) are formed at its lateral ends (43), which almost open on the edge area of the recessed handle (32). The theoretical breaking hasps (5) thus extend crosswise in the direction of travel of the pivoting-hinged lid in this area. Thus, very short integrity warranty elements can be obtained, which do not pivot and leave the locked state in the warranty position, and without breakage of the theoretical breaking hasps (5). <0}

Description

Swivel hinged lid with integrity assurance element

The present invention relates to a pivotally hinged integral cover consisting of two elements, namely a lower element having a circular shell wall and a bottom surface, which is intersected by an exhaust opening and a connected cap. to it integrally by means of a pivoting hinge with an envelope wall and a cover surface, whereby on an element of the cover there is provided a integrity guarantee element via bridges of theoretical rupture, which has a first molded means while, on the second element, there is a second molded means, so that, in the warranty position of the cover, the locking means are engaged with one another; with the other, and the locking link can be separated only by destroying the theoretical break bridges.

The hinged integral hinged lids have long been provided with integrity assurance elements to ensure that the containers are not opened by the consumer prior to purchase and are first tested when possible to replace the containers in the shelves. As a result, for a long time, elements of guarantee of integrity have been known which make the guarantee situation easily recognizable.

Initially, as a guarantee of integrity, warranty strips were first used which are configured in a circular manner around the entire cover. This principle, which stems from screwed-on covers, has caused problems for pivoting hinge covers especially during assembly. In particular when closing, the guarantee strips have often been destroyed as the guarantee strips deform after demolding and, during the closing procedure, reach the pivoting path of the cap and are thus destroyed. This problem has been recognized and so guarantee strips have been configured so that they are shorter, ie they extend as far as the half-circumference. Moreover, in this configuration, there is still a high percentage of waste since the guarantee strips always deform even when the strips are relatively small, and the circumference is reduced. Alternatively, the warranty strips, contrary to what was previously customary, were formed on the bottom member of the hinged lid hinged to the cap, and the proportion of waste was reduced. A typical example of such a hinged lid is presented in WO 93/00271.

Manufacturers of plastic lids are increasingly confronted with price pressure. In particular, in order to cope with rising raw material prices, there has always been an attempt to reduce the share of materials. One possibility has arisen so far, namely by configuring the guarantee strips so that they are always smaller. Finally, the warranty strips have been reduced to such a size that they almost represent a label or seal, covering the recessed handle that is formed in the casing wall of the cap or in the casing wall of the casing. lower element. As a result, the contact angle of the integrity guarantee element is then really low. As soon as the contact angle is almost less than 90 °, the integrity guarantee element can pivot slightly around its connection points, namely the theoretical breaking bridges, by means of which the locking means can be made to disengage on the guarantee element d integrity and on a cover member, so that the cover can be opened without destroying the integrity guarantee element or the theoretical breaking bridges. Thus, the limits of narrowing of the contact angle of the integrity guarantee element seem to be reached or exceeded.

In a variant, solutions are known on the market in which the integrity guarantee element consists of one or two lateral tongues, which are formed on a cover element by means of the theoretical rupture bridges while, on the other part of the hinge-hinged lid there is a corresponding pin which passes through the side tongues in the position of guarantee and, to ensure safety, this pin is thickened by heat treatment or welded with the pin, such so that an opening of the lid is possible only when the theoretical breaking bridges have been destroyed. This solution is certainly safe, but the assembly is particularly tedious and expensive, and the additional costs clearly exceed the economy in materials.

The object of the present invention is therefore to modify an integral hinged hinged lid according to the preamble of claim 1, so that an integrity guarantee element is maintained with a small contact angle and in a safe manner and can only be opened during a simultaneous destruction of the theoretical rupture bridges.

This object is solved by a hinged integral hinged lid having the features of claim 1.

Other advantageous embodiments of the subject of the invention follow from the preceding claims and their meaning and effects are explained in the following description with reference to the accompanying drawings.

On these drawings:

FIG. 2 is an identical view after the first opening and therefore the removal of the integrity guarantee element,

FIG. 5 again shows a diametral partial section of a cover in the guarantee position, in which the locking of the integrity guarantee element is configured in another way, and

Figure 6 shows the solution in a partial perspective view. The integrally pivoted hinged cover shown here is shown in detail only with reference to the configuration of the integrity guarantee element of interest here, while the other elements of the hinged hinged lid are only shown in simplified form.

The pivotally hinged lid 1 consists of two elements integrally connected to each other, namely the lower element 2 and the cap 3 movably and pivotally connected by means of a hinge. The configuration of the pivoting hinge is not at all relevant here and can not be seen in the drawing since, traditionally, the hinge is precisely diametrically opposite to the integrity guarantee element. The pivot hinge can be configured as a single hinge film or a click hinge. The configuration of the lower element 2 and the cap 3 is shown, for example, in FIG. 3, whereby here, again, each element which does not play a role in the invention is represented only symbolically or is not represented at all.

The lower member 2 is constituted, as usual, by a circular casing wall 20, which is insulated at the upper end by a bottom wall 21. In the bottom wall 21 is formed so that centralized or eccentric an evacuation opening 22. The lower element 2 isolates the container to the discharge opening 22 on which rests the hinged lid pivot 1. For fixing purposes, on the inner face of the wall circular casing 20 of the lower member 2 is for example an internal thread or, as represented symbolically, a number of Maintenance bosses 23. Also traditionally existing sealing means are not shown in the drawings to simplify matters.

Above the lower element 2 is the cap 3, in the closed state of the lid. Furthermore, it comprises an envelope wall 30, which is isolated by a covering surface 31, on which are traditionally affixed sealing means which are not shown here, which cooperate with the discharge opening 22. These sealing means are present on the discharge opening in the form of a hollow pin meshing with a socket or a sealing pin penetrating into the discharge opening.

In one of the two pivotally hinged lid members 2, 3 is traditionally formed a recessed handle 32. In the example shown here, the recessed handle 32 is formed in the casing wall 30 of the cap 3. The handle recessed 32 is fully visible in Figure 2, since here the integrity guarantee element is omitted, which traditionally covers the recessed handle 32 to a large extent or completely. The integrity guarantee element is globally indicated by the numeral 4. In the embodiment shown here, it is in the form of a seal or a label. In the embodiment according to Figure 1, the integrity guarantee element is made in the form of a virtually square plate and is adapted to the shape of the recessed handle 32. The integrity guarantee element therefore has an upper edge 41 which extends naturally projecting and corresponds quite to the curvature of the lid, and a lower edge, which is configured in the same way. In addition, the element of Integrity guarantee 4, which is here configured in the form of a plate 44, has two lateral boundaries 43 which follow almost the contour of the recessed handle 32.

The integrity guarantee element can naturally have different configurations. In particular, the plate 44 may be smaller, larger or have a size identical to that of the recessed handle. If one affixes, as so far, the connection of the integrity guarantee element 4 along the lower edge 42, one can clear without problem this element. However, it is essential for the invention and particularly simple, surprisingly, to achieve the connection of the integrity guarantee element 4 by means of theoretical break bridges 5, which are arranged along the lateral delimitation 43. As a result, the theoretical rupture bridges are substantially transverse to the opening movements in this zone. The opening movement of the cap 3 in the area of the integrity guarantee element is almost an axial displacement while the theoretical breaking bridges 5 are arranged in a radial orientation. Naturally, it is not important that the theoretical break bridges can extend only almost radially, but it is essential that they extend transversely to the direction of movement, whereby it is possible to maintain an inclination compared to the axial direction of about 45 degrees. For such a solution to be possible, the integrity guarantee element 4 or the plate 44 must be separated by such a distance from the lid element to which it is connected as an element of the tool. injection can find a place behind. This can be done very simply in that the plate 44, as shown here, is directly formed on the recessed handle 32. In this way, the integrity guarantee element 4 does not need to protrude a lot relative to the casing wall 20 of the lower element. 30 or the cap 3.

In the example shown here according to FIG. 1, the integrity guarantee element is arranged so that it extends above the separation plane T between the cap 3 and the lower element 1 of the lid hinged hinge. While here, the integrity guarantee element 4 is connected to the cap via the theoretical breaking points 5 and the plate 44 has, as part of the guarantee of integrity, an opening 45. as the first locking means, the second locking means comprises a latch 46 which meshes with shape in the first locking means 45 according to the configuration of the aperture. In order to open the lid, the thumb is placed in the recessed handle 32, and the integrity guarantee element is thus gripped by the rear and pivotally broken.

Moreover, a simple upward pivoting makes it possible to open the lid and thus simultaneously destroy the integrity guarantee element. Consequently, the theoretical break bridges are almost configured in the form of pyramids or in a triangular fundamental form in the figure, whereby the base or an edge of the triangle bites on an element of guarantee of integrity while the tops of the bridges of theoretical rupture resembling a triangle in terms of plotting bite on each wall of envelope on which is formed the element of guarantee of integrity, the example shown here is therefore the cap 3. This can be achieved in a particularly advantageous manner in that the plate 44, as integrity assurance element 4, almost follows the contours of the recessed handle 32, and the slot between the plate 44 and the edge of the recessed handle 32 5. In order to guarantee that thieves can not unlock the integrity guarantee element without destroying the theoretical rupture bridges, on the lower element 2 a bulge 6 is formed which surrounds the protruding element of the integrity guarantee element 4, so that a rearward gripping is made impossible.

Whereas, as mentioned above, in this embodiment, the integrity guarantee element 4 is formed on the cap and that it partially covers the lower element 2 above the separation plane (T), of course, it is also possible to configure a hinged hinged lid so that the recessed handle is substantially affixed in the lower member 2 and the integrity guarantee element is formed on the lower member 2 via theoretical breaking points 5 and extends in the region of the cap 3 partly above the separation plane (T). In this case, of course, the second locking element 46 must be formed on the cap 3. Instead of what has been described previously, namely the first locking means 45 is an aperture and the second locking means on the other The cover element is a lock, it is of course also possible that the first blocking means 45 is only a notch on the rear face of the plate 44, while, parallel, the lock is limited to a rib with a sharp edge which meshes into the notch on sharp edge on the back side of the element of guarantee of integrity. In particular, in hinged hinged lids having a relatively large diameter, this solution can be considered when the strength of the material is sufficient to form a corresponding sharp-edged notch in the plate 44. This should be relatively deep so that, in larger covers, it is possible to achieve a sufficient pivoting trajectory, which makes it impossible to voluntarily release the security element.

As shown in FIGS. 5 and 6, it is not mandatory for the integrity assurance element 4 to cover an element of the lid element on which the integrity guarantee element is not formed. . This can be done in such a way that a first locking element is affixed to the rear face of the integrity guarantee element, such as for example a sharp-edged cleat, while on the lower element 2 of the lid 1, there is a second locking member 46, which is here in the form of a hook extending in the area of the cap upwards. This hook 46 can also be embedded in the element of guarantee of integrity, which supposes that the first locking element is again an opening 45.

In particular in closures having a smaller diameter, however, the version with an aperture as the first locking means and a latch or hook as the second locking means and the proven solution. With the optimum configuration, the lock is preferably applied so that it extends at least almost with its upper edge to the height of the bottom surface 21. The variants described here of the locking means serve simply as an example and are in no way limiting. In addition to the advantages mentioned, the solution as represented in FIGS. 1 to 4 has the advantage that the connection points of the theoretical break bridges can be dimensioned so as to be very small, and it is therefore possible to establish clear separation points, which virtually prevent any possible injury in the form of tearing of the skin.
