Description

The invention relates to a container construction and relates to the measure that a container wall is flexible and is provided with a notch or line of weakness which, if bent, leads to breakage, thereby creating a To create an opening for the container access.

The container construction according to the invention is primarily for use in the pharmaceutical industry as Containers for pharmaceutical compositions have been developed and used and will be described below with reference thereto and illustrated, however, the advantageous properties of the invention can be found in many different applications come.

In the pharmaceutical field, the goods are often packaged according to their dosage, for example with one or two Capsules per packaging unit, and not in large quantities, like this that a more precise monitoring of the temporal distribution of the

Drug consumption is effected and sustained. Such packaging units must be relatively cheap so their use is justified.

In certain areas of drug packaging, it may be desirable not just to reduce packaging costs as much as possible to keep low, but also to simplify the opening process of the pack as much as possible without the protection of the content and the control of the distribution suffer as a result. In other areas of pharmaceutical Administration, however, it may be desirable to have packaging available that is not only economical, protective for the contents and suitable for properly controlled dosing, but also in which the opening process of the packaging is sufficiently difficult that this provides protection given to the curiosity of young children.

The invention is based on the object of creating a container construction which meets the specified requirements well, which is therefore sufficiently economical to allow the packaging of small units or doses and thus to enable precise control of the removal, which also includes the contents effectively protects against physical as well as chemical damage and with which the degree of ease or difficulty with which the packaging can be opened can also be preselected. According to the invention, it is assumed that a container wall is flexible and is provided with a score line along which a break occurs when bent _{3 in} order to create an opening into the interior of the packaging. In particular, the invention is characterized by two flexible, opposing sheet pieces, by connecting means which connect the two sheet pieces to one another along a closed circumference, the enclosed area within this closed circumference for inserting a content

has no lanyard, and by a score line on the enclosed area of one of the surface pieces, which is sufficiently breakable to withstand a bending of the surface pieces along the score line these break through, creating the trapped Area to access the content is open.

The invention is described below using an exemplary embodiment with reference to the drawing. It demonstrate:

Figure 1 is a perspective view from below of a strip of packs that represent a container construction according to the invention, showing the internal structure thereof files have broken off;

FIG. 2 shows a section in a plane 2-2 in FIG. 1 _f in the reverse position of the strip;

FIG. 3 shows a section in a plane 3 - 3 in FIG. 2;

FIG. 4 shows, on an enlarged scale, a partial section corresponding to FIG. 3, one in FIG. 3 in the right half of the picture The dot-dashed area 4 during an early phase of the opening processj and

FIG. 5 is a perspective view of the underside of an individual pack in a later phase of the opening process.

As can be seen from Figure 1, contains a long packaging strip 10 a plurality of individual packs 11 arranged side by side in a row and with one another are releasably connected.

The packaging strip 10 can automatically consist of two elongated flat material strips 12 and 13, such as metal sheets or foils, which are arranged opposite one another and connected to one another in a suitable manner will.

The strips of material 12 and 13 can be preformed to a certain extent be, for example, the (according to Pig * 1) upper sheet 13 at regular intervals with an upwardly extending and downwardly opening depression or bulge 15 or be provided with any other shape that holds a content. The upwardly protruding bulges 15 can, for example be of the type referred to in packaging technology as bubbles.

The other material strip 12 on the underside (according to FIG. 1) can have certain score lines, cuts or lines of weakness be preformed »For example, at a mutual distance along the strip of material 12, for example on its underside, a plurality of score lines 16, cuts or lines of weakness may be arranged, all parallel to one another across the The entire width of the strip of material 12 run · The strip of material 12 is thus divided by the various score lines 16 into a plurality of generally rectangular surface pieces 17, each of which lies opposite under one of the indentations 15 holding the content.

In the exemplary embodiment described, the material strips 12 and 13 have the same or the same limits laterally the same extent, with the indentations 15 holding the contents all closer to a pair of the coincident ones lateral longitudinal edges of the material strips 12 and 13 are arranged than on the other pair of the lateral longitudinal edges (Figure 3). More specifically, the side edges 18 and 19 of the lower one fall Material strip 12 each with one of the lateral

Edges 20 and 21 of the upper strip of material 13 together; and the upwardly (downwardly in Pig. 3) projections or the contents holding bulges 15 are closer to the edges 18 and 20 than arranged on the edges 19 and 21.

Generally in the middle of each sheet piece 17 is spaced between the respective adjacent two transverse score lines or lines of weakness 16, a score line or line of weakness 22 arranged, which expediently runs in a U-shape, each U-shaped notch or weakening line 22 contains a final, more or less arcuate base piece 23, which extends generally in the longitudinal direction of the material strips 12 and 13 extends and in the vicinity of the lateral edge 19 of the material strip 12 at an inwardly directed distance from this Edge runs · The base piece 23 of the score line is thus in the transverse direction of the packaging strip 10 at a distance of the closest bulge 15 holding the content. Each base piece 23 may be generally straight or arcuate which depends on the desired degree of difficulty of opening the resulting package, how even more clearly is set out "

From the opposite ends of each base piece 23, which are spaced inwardly from the adjacent score lines 16 dividing the material strips, two leg score lines 24 formed by the U-shaped score lines or lines of weakness 22 extend generally parallel to one another near the associated bulge 15 in the direction of the side edge 18, just before they end. The leg score lines 24 can be extensions from the opposite ends of the score line base piece 23 ₉ to which gede is connected via a connecting or corner score line 25, which has a larger or smaller radius of curvature according to the desired degree of difficulty of opening, as will be described in more detail .

409818/0263

Each pack 11 can therefore be used as between two parallel Kerboder Lines of weakness 16 are thought to run with the (According to Pig, 1) upper surface piece 27, which is essentially congruent and arranged opposite one of the lower ones Elächenstüeke is 17. Each of the top patches 27 is with one of the bulges 15 holding the contents, while each lower surface piece 17 with the score lines from the Base piece 23 and the leg score lines 24 may be provided. The surface pieces 17 and 27 of each pack 11 thus run generally parallel to one another and with their end faces facing one another, with the exception of the bulges 15 ″ for connection of the edge areas of the packs 11 are the upper and lower sheet pieces 17 and 27 by means of connecting means such as glue, Shermo closure, high-frequency welding or the like «connected to one another. In particular, there is provided an interlayer joint seal 28 of closed, generally rectangular shape, which serves the Jlächenstücke 17 and 27 in their to hold opposite position.

In practice it has proven to be useful to use the upper one and make the lower strip of material 12 and 13, respectively, from semi-rigid polyvinyl chloride about Θ.25 mm (0.01 ") thick. However, other materials with the required properties can also be used.

In use, a single pack 11 can be removed from the packaging strip 10 can be removed by breaking along one of the notch or weakening lines 16. See the notch or Lines of weakness 16 extend to the side edges of the sheet metal or foil 12, the outermost pack 11 can be separated from the rest of the packaging strip 10 can be easily separated by manual pull »

Then only the superimposed layers of the planar pieces 17 and 27 need to be bent along the score line in the area of their base piece 23 _e This can be done in this way.

40981 8/0263 / 7.

leads to the fact that the end part of the pack 11 on the right in FIG from the position according to Pig. 3 bent into the position shown in FIG will. The surface piece 27 is bent to a bend 30 (Pig, 5) and the remaining material 31 (Pig. 3) along the · The base piece 23 is broken as a result, as shown in FIG. 4 shown is. There are two edges 32 and 33 along the earlier base piece 23 of the score line. The edge 32 of the torn apart base piece 23 can be grasped with the fingers or by inserting a fingernail »by a further separation around the corner score lines 25 and effect along the thigh score lines 24 au and out of the intermediate Material to form a tab 35 (Fig. 5). The tab 35 gives access to the bulges 15 for a convenient removal of the contents indicated by dash-dotted lines in Fig. 2 and 3 "

By choosing the depth of the cuts or grooves that make up the base area 23 of the score line or line of weakness, the thickness of the remaining uncut material, the brittleness or Breakability of the surface piece 17 and the radius of curvature of the corner score lines 25 can determine the degree of ease or difficulty that should occur when the pack is opened can be predetermined as desired.

The strips of material 12 and 13 are indicated as being preferably made of plastic, but other suitable ones can also be used Material used to achieve the desired protective properties and the level of difficulty in opening. For example, the material, its thickness and the properties of the notch or weakening lines can be selected in this way be that several bending movements back and forth are required to get the desired break along the score line

The invention thus provides a container structure that is extremely simple in construction, durable, protective and reliable is in use and economically in mass, manufacturing process can be generated.
