BRIEF SUMMARY
BACKGROUND
1. Field of the Invention
The field of the present invention relates generally to packs for pourable products, and more particularly to such packs that consist of an inner container surrounded by a separable supporting jacket.
2. Discussion of Related Art
This invention relates to a pack for pourable products, such as liquids or free-flowing fine granules or the like, which consists of an inner thin-walled blown plastic container intended to hold the product and of a base- and cover-free supporting jacket with an upper supporting edge which surrounds the blown plastic container and bears against it in the in-use position of the pack, the blown plastic container preferably being provided with an upper bearing shoulder for resting on the supporting edge of the supporting jacket and comprising a recess. The supporting jacket is provided with laps which are designed to fold at least locally into the recess and to serve as fixing elements for the supporting jacket and which form a carrying handle, detent means being provided for the folded laps.
One such pack is known from applicants' DE 39 21 258 A1. In this known pack, the blown plastic container can be made by blow molding from a blow-moldable plastic so that the plastic content of the pack can be kept very small. The pack is made sufficiently stable by the supporting jacket of paper, cardboard, corrugated paper or a similar material. The handling properties are guaranteed by the recess in the container and the corresponding opening in the supporting jacket. In addition, optimal support of the plastic container is achieved via the upper supporting edge of the container on which the bearing shoulder of the blown plastic container rests in use. The two parts of the pack (blown plastic container and supporting jacket) are formed by the laps of the supporting jacket which are designed to be folded into the recess and which, folded together, also form the carrying handle of the pack.
With this known pack, it is readily possible by virtue of the design of the laps to join the two parts of the pack to one another and also to separate them from one another so that they may be separately recycled. After emptying the pack, the user may separate the two parts of the pack from one another and dispose of them separately. In particular, the outer supporting jacket of the pack may be disposed of as wastepaper. Although this known pack is thus very user- and recycling-friendly, it still has disadvantages. In the known pack, the connection between the two parts of the pack in its in-use state is still not entirely safe, as is necessary particularly when the pack is completely full.
SUMMARY OF THE INVENTION
Accordingly, an object of the invention is to provide a solution in which the connection between the inner and outer parts of the pack would be improved without any effect on the handling properties of the pack.
In a pack of the type mentioned above, the solution provided by the invention is characterized in that the detent means are in the form of cams which are integrally formed on at least one end of the handle laps of the supporting jacket, and with which a ramp-like projection formed on the plastic container is associated in the pivoting range of the recess.
This construction maintains the good handling properties of the pack and, at the same time, provides for a safe connection between the two parts of the pack, the blown plastic container and the surrounding supporting jacket. This is achieved by the combination of the cams on the handle laps, which form the detent means, and the ramp-like projection on the plastic container. At the same time, the presence of the ramp-like projection avoids a thin zone in the blown plastic container so that the other wall regions of the container are not unnecessarily overdimensioned.
In one advantageous embodiment of the invention, the ramp-like projection is in the form of a run-up ramp adapted to the pivoting range of the associated cam of the handle lap. This embodiment further improves the handling properties of
