EP2341003B1 - Packaging with child safety mechanism - Google Patents

Description

The invention relates to a packaging according to the preamble of claim 1. The packaging consists essentially of a preferably made of a blank basic body, in the cavity of a carrier is slidably mounted. The carrier may, for example, be a blister carrier for holding at least one blister or a carrier for other objects. Such blisters are used, for example, for packaging pharmaceutical products, such as tablets or capsules, and have been known and used for a long time. Packaging with withdrawable blister carriers are known and familiar to the person skilled in the art under the term "slide packaging". The pusher box has child-proof locking means to ensure that children are unable or unwilling to open it.

A slider package is for example from the WO 2006/068602 A1 known. The packaging shown therein has a basic body made of a blank, in the cavity of which a blister carrier or another insert is arranged so as to be displaceable in a limited manner. As a securing means for parental control, the packaging on the main body blank-hinged locking portions, which form a hollow profile in the finished, parallelepiped-shaped body, which serves as a stop for a arranged on the blister carrier locking tab. The child safety (or blocking position) can be canceled by pressure on a button-like tab, which is arranged on an upper side of the hollow body and is defined by a circular cutting line. The complicated design of the child safety means that the packaging is relatively difficult to produce. Another disadvantage is that the cost of materials is quite large. Another disadvantage of this cardboard packaging, which is exclusively by cutting, Folding and gluing operations is made, is that it is less stable and soon shows signs of wear in multiple use. Also with regard to parental control, the packaging can not meet higher requirements. Thus, it has been shown that the packaging of children can be opened relatively easily. Because of the predetermined by the button-like tab opening the top can be easily torn and then the blister can be removed.

It is therefore an object of the present invention to avoid the disadvantages of the known and in particular to provide a package that meets the one hand, high standards of parental control and on the other hand is inexpensive and easy to produce.

These objects are achieved with a package having the features of claim 1. The carrier has a resiliently hinged to a base portion latching tongue. A housing wall of the main body has a latching shoulder, wherein the latching shoulder cooperates to create a latching connection in the rest position or blocking position with the latching tongue. The latching tongue may have a front edge which is supported or can be supported on the rat shoulder and thus effects a tension-resistant locking in the rest position. The securing means are preferably designed such that, for example, after the first opening or creating the removal position when the carrier is pushed back into the base body, it can be latched into the base body. Attempts a user to pull the latched carrier (rest position) from the body, so the latching tongue abuts the locking shoulder, whereby the withdrawal of the carrier is prevented from the rest position. Only after the user through targeted force the engagement between locking tongue and Retracting shoulder picks up, the carrier can be pulled out. The movement takes place in a longitudinal direction.

The carrier may be configured as a blister carrier, wherein one or more blisters may be attached to the base portion. Base section and latching tongue can be formed from a single blank of cardboard or paperboard laminate. At least one blister can lie flat on the base portion and be secured thereto or attached thereto. The base portion may extend approximately plane-parallel to a ground plane. The term "blister" is understood below to mean a packaging unit which contains a base film provided with at least one receptacle for receiving packaged goods and a pressure-sensitive cover film covering the receptacles. To remove the packaged goods this is pushed through the cover sheet, which consists for example of aluminum. Simple blisters are also known as "blister strips".

In a first embodiment, the latching shoulder may be arranged on an upper side opposite to the carrier and preferably extending substantially plane-parallel to a ground plane. Of course, the top does not have to be aligned exactly plane-parallel to the ground plane. The top can also be inclined to the ground level. It is also conceivable that individual wall sections of the upper side can have a curvature. Furthermore, the top may consist of several wall sections with different distances to the ground level.

Alternatively, it would also be conceivable to provide the latching shoulder on a housing wall, which protrudes from the floor level. In this case, the locking shoulder could be a longitudinally extending hereafter referred to as the "longitudinal side wall" designated housing wall.

In a preferred embodiment, the locking shoulder may be formed by a step in the housing wall. The step can form a transition between two housing wall sections. This stage can be arranged on the aforementioned upper side or possibly on the longitudinal side wall of the main body. Such a step can be materially connected to the adjacent housing wall sections. Folding or gluing operations to form a locking stop are not required. The step is thus to some extent integrated in the housing wall and can be created by appropriate shaping of a sheet material. The step forms with the adjacent housing wall sections a contiguous profile contour with a constant or variable wall thickness.

In a further embodiment, the main body or the hollow body of the main body may have a latching tongue receiving area for receiving the latching tongue in the rest position. A carrier receiving region can connect to the latching tongue receiving region in the direction of the opening, wherein the latching shoulder lies in the transition region between latching tongue receiving region and carrier receiving region. In a blister package, the carrier receiving area may be a cup receiving area in which the wells of the blister may be received.

It can be advantageous if the opening receiving area adjoining the support receiving area for receiving a preferably U-forming deflection of the carrier, wherein a housing wall portion associated with the end region is increased relative to a housing wall portion associated with the cup receiving area. The end wall of the associated housing wall section can be approximately plane-parallel to the ground plane. The deflection can be formed by a joint strip adjoining the base section and a further section, wherein the further section has a free end-side edge.

The housing wall section assigned to the carrier receiving area and a housing wall section assigned to the latching tongue receiving area can extend approximately plane-parallel to the floor plane. The distance between the respective levels determines the Rastschulterhöhe. In this way, a step-like construction of the housing wall can be created particularly easily.

The carrier may consist of a single blank of cardboard or paperboard laminate. For special packaging solutions but also plastic materials would be conceivable.

The base portion and the latching tongue may be separated by fold lines. Between the base portion and locking tongue a hinge strip can be arranged. At least in the rest position base section, hinge strip and locking tongue can define a U-shape in a side view. Such a blank is particularly simple and inexpensive to produce.

An advantageous child safety can be created if the housing wall in the latching tongue receiving area for releasing the latching connection by elastic deformation and without further weakening is pressed inwards. With such a configuration can also be ensured that the package can not be destroyed or at least very difficult of children to circumvent the child safety.

The main body may have longitudinal side walls extending in the direction of displacement or longitudinal direction, wherein the boundary the sliding movement when pulling out of the carrier, the side walls may have a taper, which form a stop for the latching tongue and / or other blocking means. This taper can form a locking shoulder to give the stop.

Alternatively or additionally, each laterally hinged locking segments can connect to the base portion, which can be hit when pulling the carrier to the taper or to the locking shoulders. The blocking segments can be arranged so resiliently on the base portion that they are preferably frictionally retracted when pulling out of the carrier on the side walls of the body. As a blocking agent but also on the base portion formed and lying on the same plane surface locking means come into question.

In a particularly preferred embodiment, the base body may be formed in two parts. The two-part body can consist of a bottom part and a molded part. Depending on the configuration of the securing and, if appropriate, blocking means, the packaging insert must be inserted before the assembly of the basic body (that is to say before the molded part is fastened to the bottom part). Of course, however, variants are also conceivable in which the packaging insert is inserted into the cavity of the cavity only after assembly of the base body and is latched thereto. Such a two-part design of the body could also be advantageous for conventional child-resistant packaging without the previously described locking shoulder.

The bottom part can be formed by a lying in a ground plane, flat, planar component. Such a component is particularly easy to produce. Another advantage of a such sheet-like component is that this is particularly easy connected to the second component of the body (molding) and preferably glued.

It may be particularly advantageous if the cavity is predetermined only by shaping of the molded part. The molded part may be a component produced by a casting or forming process, in particular by an injection molding, thermoforming or blow molding process, preferably made of plastic. Particularly preferably, the molding is made of a non-transparent plastic to optimize the parental control. Thus, a relatively rigid one-piece component is created. Because compared to folding cartons made of cardboard, no fold lines or lines of weakness are to be provided, at least with regard to the shaping, so that the packaging is characterized by a comparatively high stability. The molded part has the advantage that relatively complicated outer and inner contours for the main body are possible.

The molding may have a trough-like configuration for defining the cavity, which is surrounded by an edge portion. Such a configuration could be made particularly simple and inexpensive by means of deep drawing.

The molded part can have a surface section lying flat on the bottom part, which at least partially forms an adhesive or sealing surface for connecting the bottom part to the molded part. In this way, a peripheral edge fixation can be created. For the attachment of the two components in particular adhesives such as hot melt adhesives or so-called hot-melts are suitable. In question, however, also known to those skilled in the term "seal" known attachment method (eg Wärmesieglung, ultrasonic sealing). Of the Edge portion of the molding can be provided for this purpose with a sealing layer which can be activated by exposure to heat or ultrasonic vibrations, so that a weld or surface adhesion (adhesion) takes place.

The aforementioned advantages can also be achieved by other securing means for child safety. A slider package containing a consisting of paper, cardboard or a cardboard laminate bottom part in combination with a molded part made of plastic, which was preferably created by an injection molding or deep drawing process, so could also be the subject of an invention on its own.

In a further embodiment, finally, the frontal opening of the base body can be closed by a tear-off closure predetermined by predetermined tear lines. After the tearing off of the closure, the aforementioned opening is formed. Such a closure has the advantage that the packaging content is protected relatively reliably against external influences. Another advantage of the closure solution is that after the first tearing of the closure of the original state is no longer producible and thus a guarantee function is ensured.

It may be particularly advantageous if the closure comprises both parts of the bottom part and of the molded part.

In the region of the frontal opening and / or in the end region, in each case a recess for facilitating the detection of the carrier can be arranged in the top side and / or in the side opposite the top side, whereby the handling of the packaging is facilitated. The recess can be separated by a separable, before the first opening of the package, be predetermined by predetermined ripples tongue locked. The desired tear lines associated with the tongue can be part of the predetermined tear lines which separate the closure from the rest of the main body. The tongue can therefore be formed on the closure and tear off the closure together with this can be separated from the rest of the package. The tongue can be predetermined, for example, by a semicircular desired tear line.

FIG. 1 shows a designated 1 package for packaging a (not shown) blister. The package 1 contains a basic body 2 which predetermines a cavity. The basic body has a trough-like configuration which essentially forms the cavity in which a blister carrier or another carrier is received or can be received. This tub is surrounded by a rim portion 24 to which a flat, designated 5 bottom part is attached. A bottom plane in which the bottom part 5 extends flat is indicated by B.

At the edge portion 24 close to side walls 23, 27, which protrude from the ground plane B. The side walls contain two longitudinal side walls 23 extending in the longitudinal direction A and two transverse side walls 27, which are opposite one another. The side walls finally merge into a housing wall forming the upper side 7, which is characterized by a step-like configuration.

As FIG. 2 shows, the packaging 1 consists essentially of three components, namely from the bottom part 5, a molded part 6 and from the blister carrier 3, on which a blister 4 is attached. Of course, the carrier 3 could also be used for other purposes, attaching a blister is not mandatory. The blister carrier 3 is made of a single blank and includes a base portion 13, on which folded on the two opposite end faces inwardly Connect U-forming ends. At the front end, the base portion 13 is adjoined by a hinge strip 28, which is connected more or less vertically to the base portion and to which another portion 29, which runs approximately parallel to the base portion, adjoins. In the area of the rear end face, a latching tongue labeled 11 can be seen. This latching tongue 11 cooperates with a latching shoulder 10 associated with the molded part for creating a childproof lock. The exact mode of action and the constructive structure of the parental control are described below with reference to FIG. 3 and particularly FIG. 5 seen.

The packaging 1 has a closure 8, which is an integral part of the packaging. The closure 8 is arranged at the front end of the aforesaid end region and can be torn off from the remaining packaging by attaching predetermined tear lines 25.

For the first opening of the package, the user must first press a tongue 26, after which the closure 8 can be separated without much effort. A severed closure is in FIG. 3 denoted by 8 '. Such an engagement on the tongue is indicated by a curved arrow. Before the blister carrier can be pulled out of the base body through the opening 12, the parental control of the packaging must be released. This is done by pressure on the body in the region of the rear housing wall portion 16. This is off FIG. 4 recognizable. The pressurization area is indicated by a gray-colored circular area and the direction of displacement is indicated by the arrow A. A complete withdrawal of the carrier 3 is prevented by the locking shoulders 14 in the molded part 6, which with the locking segments 15 (FIG. FIG. 2 ) interact with the carrier.

The exact structure and operation of the packaging shows a longitudinal section through the packaging ( FIG. 5 ). The upper side of the housing has a, opposite the adjacent housing wall sections 16 and 18 recessed middle wall portion 17. This results in a step-like configuration of the housing wall, which divides the cavity into three areas: a predetermined by the housing wall portion 16 locking tab receiving portion 20, a predetermined by the housing wall portion 17 carrier receiving portion 21 and a predetermined by the housing wall portion 18 end portion 22 (FIGS. FIG. 5 ).

The folded-in latching tongue 11 is biased due to the material-related resilience and pushes upwards. This can ensure that the front edge of the latching tongue 11 is in engagement with the latching shoulder 10. As a result of this interaction between latching tongue 11 and latching shoulder 10, the blister carrier 3 is tension-proofly mounted in the base body with respect to the A-direction. By applying a compressive force F, the housing wall section 18 and thus also the latching tongue 11 can be pressed downwards, whereby the engagement can be canceled and the blister carrier 3 can then be pulled out in the A direction.

Out FIG. 5 is also clearly visible that the molding 6 has a trough-like configuration, which is surrounded by the edge portion 24. Evidently, the individual housing sections 16, 17, 18 extend plane-parallel to the ground plane B. At the end associated with the opening end is approximately a U-forming deflection 9. On the other end face is the latching tongue 11. The molding 6 is a through a deep drawing method or blow molding (English "blow molding") preferably made of a film material, relatively thin-walled plastic component (eg PE, PA, PVC or PPE).

The FIGS. 6 and 7 each show plan views of the molded part 6 and on the bottom part 5. The individual, transversely to the longitudinal direction A extending gradations in the top wall forming the housing wall are clearly visible.

In FIG. 7 is a border represented by a continuous dashed line recognizable. This outer edge forms an adhesive or sealing surface for fastening the molded part 6 on the bottom part 5. The desired tear line, which runs in the bottom part 5, is indicated at 31.

As shown in the illustration of the blister carrier according to FIG. 8 shows, are on the same front side as the latching tongue 11, but arranged laterally designated 15 locking segments.

How out FIG. 9 proceeding, the blister carrier 3 on which a (not shown here) blister 4 is attached, can be made from a single blank of cardboard or cardboard laminate. In FIG. 9 are predetermined tear lines (eg perforation lines) represented by dashed lines; Fold lines are shown by dash-dotted lines. The present blister carrier 3 differs from the blister carrier according to the preceding Figures 2 and 3 only in that it is adapted for a different blister arrangement. Specifically, the blister carrier 3 is provided for a "20-blister" or two "10-blister". The base section has twenty fuse segments 30 assigned to the push-through regions of the blister or blisters, which are each predetermined by circular predetermined tear lines. The fuse segments can also be omitted or removal from the blister cups can also be ensured by other means.

The laterally arranged blocking segments 15 are separated by folding lines 34 running in the longitudinal direction A from the base section and can be folded inwards. The fold lines can be predetermined in particular by rolled lines. The base portion 13 and the latching tongue 11 are separated by a hinge strip 19 formed by fold lines 32, 33. From the illustration according to FIG. 9 is clearly seen that the base portion 13 is widened in the rear, the latching tongue 11 facing region, which can be practically ruled out that the blister carrier can be completely pulled out of the package. Theoretically, it would also be conceivable to connect the fold lines 34, which specify the articulation for the blocking segments 15, directly or flush to the side edge.

FIG. 10 shows a further embodiment of the package, in which the locking means are not arranged in the region of the top, but in the region of the transverse sides. Specifically shows FIG. 10 Each longitudinal side wall 23 has a predetermined by a taper locking shoulder 10 which predetermine a stop for the locking tongues 11 of the blister carrier 3 in the rest position. The present embodiment also differs from the preceding embodiment in that the blister carrier 3 can also be inserted only after the assembly of the base body 2 and locked with this.
