Packaging with a cover and at least one container enclosed by this

The invention relates to a package and, in particular, to a package with one folded from a blank and at least one shell enclosing the container.

It is generally required to form a package. den by placing a Einwiekler in the shape of a tubular Sheath around at least one container, for example a scha1enförraigeη container, is provided, such as this in the case of food products intended for the consumer, such as oils, fats, ice cream and like, can be used. The containers used are often with a removable lid or closure equipped with a circumferential flange running downwards, which lies outside the body part of the container when the lid or closure is in the closed position. takes.

Containers - with the exception of those with a rectangular top - with an outwardly protruding edge or flange have hitherto been introduced into a tubular casing by making cutouts or openings in the

409845/0377

Sidewalls of the envelope have been provided through which the rim or flange protrudes. The width of the envelope is usually somewhat narrower than the corresponding maximum width of the edge or flange _r so that the container is held firmly and securely in place, but it is also possible to move or remove the container from the envelope without opening and tearing it.

For this purpose, the invention provides a packaging with an open-ended casing and at least one container a body part and a downwardly directed circumferential flange located outside the body part before, wherein the envelope from a one-piece blank along fold lines to form a top wall, two opposing side walls and a bottom wall folded and along overlapping edges is fixed to form a tubular envelope and retaining tongues extending upwardly from the side walls on each side of the envelope and between the circumference and the body part of the container to fix the container lie within the envelope.

The upward-facing retaining tabs make for a more positive one Fixation of the container within the envelope to form a package that is safer and more theft-proof is than previously proposed packaging. In addition, the envelope can be used to form a package with containers Substantially rectangular top can be used as the tongues hold the container within the envelope and it is not necessary that part of the rim or flange of the container be passed through openings in the side walls protrudes.

To facilitate erecting the envelope around the container to form a package, the base can be any Tongue preferably run parallel to the top wall and can

a broken erecting fold line running parallel to the top wall in each side wall with the base of the Tongues curse and be interrupted by them. A combination of folding the envelope along the fold lines, which connect the side walls to the top wall, and allows along the interrupted erecting fold lines it that the tongues between the peripheral flange and the body part without tension of the shell or formation any unwanted creases can be inserted.

Depending on the height of the circumferential flange and depending on the distance with which this is arranged outside the body part of the container, can the uppermost edges of the tongues are spaced below the underside of the top wall for erecting to facilitate the sheath without adversely affecting the holding effect of the tongues. This training enables it that in the vicinity of the retaining tongues cover flaps are separated from the side walls and with the top wall lie in one plane and interrupt the fold lines connecting the side walls with the top wall and with regard to their shape correspond to that of the upper part of the container and are provided above the same. The lid flaps can not only change the appearance of the top improve the packaging, but also take care of it in an advantageous manner to a certain extent a crush or pressure protection on the circumferential flange. this applies in particular if the peripheral flange protrudes outwards from the side walls of the casing.

If the packaging contains only a single container, the length of the top wall of the envelope can of the top of the container so that the top of the container is completely covered. To optimize Depending on the material requirements, the remaining walls of the shell can be somewhat narrower or shorter. Should this be desired, so the material requirement can be further reduced by

the length of the top wall of the envelope is less than that of the top of the container is made. If a recessed cap is provided for the container extension tabs may be folded down from the top wall and substantially toward the top wall have parallel free edges which frictionally contact the surface of the recessed closure cap. The closure flaps can also have side edges which correspond to the substantially vertical edges of the touch the recessed cap by rubbing it. The closure tabs form useful grip options for fingers to lift the package;

In the following, embodiments of the invention are further developed described in detail with reference to the schematic drawings; in this shows:

Upper wall 5, two opposing side walls 6 and a bottom wall 7 divided. An adhesive flap 8 is provided along a fold line 9 on the bottom wall 7.

In the side walls 6, interrupted erect fold lines 10 parallel to the fold lines 2 and 3 are provided, which meet on incisions 11, which are located between the Erecting fold lines 10 and the corresponding fold lines 2 and 3 extend. Parts of the incisions 11 form one another opposite side edges of holding tongues 12, the base of these holding tongues with the straightening fold lines lie in a line. The remaining parts of the incisions form opposing edges 13 of openings 14 each with an edge 15, each of the upper edge of the Holding tongues 12 forms. Cover flaps 16 are from the side walls 6 in the area between the incisions 11 for interruption of the fold lines 2 and 3 separated, the free edges 17 of the cover 16 the remaining edges of the openings 14 form.

FIG. 2 shows a package which is formed using the casing produced from the blank of FIG. 1, which in turn is erected all around a container 18, which is also in view by means of a closure lid Upper part formed by rounded corners has a downwardly directed circumferential flange 19, which is spaced outside the body of the container is arranged, as can be seen in particular from FIG. The retaining tongues lie between the circumferential flange 19 and the body of the container for fixing the container in the shell, the upper edges 15 of the holding tongues 12 with Distance below the underside of the top wall 5 are provided. As a result of the rounding of the corners of the upper part of the closure lid the width of the top wall is slightly smaller than the maximum width of the closure lid, so as to Sheath to give a tight fit around the container with the result that the flange 19 is slightly outside

the side walls 6 protrudes. The cover flaps 16, which are separated from the side walls, are above the Upper part of the closure lid, the edges 17 of the lid flaps 16 to a certain extent for pressure resistance ensure that the risk of damage to this part of the side walls 6 of the Sheath protruding peripheral flange 19 is reduced.

Figure 3 shows one of the side walls 6 in a partially upright position. To take the in the left part of the In the position shown in FIG. 3, the side wall has been folded along the two fold lines 2 and 10, so that the retaining tongue 12 engages under the peripheral flange 19. To completely unfold the side wall, it is folded further along the fold lines 2 and 10, to be precise of arrow A until the side wall touches the adhesive flap 8 and is glued to it.

In the embodiment of Figures 1 to 3, the interrupted Fold lines 10 are required so that the casing is erected without the formation of undesirable crease lines in the casing can be. The Faitlinien 10 can be omitted where the depth of the circumferential flange, the distance between the upper Edges 15 of the retaining tongues below the underside of the top wall 5 and the type of material of the envelope allow this.

According to FIG. 7, a package can contain more than one container; the package of Figure 7 contains two containers. The packaging corresponds essentially to that of Figures 1 to 3, with a retaining tongue in each of the Side walls 6a for each container 18 is provided.

Figure 4 shows an alternative embodiment in which the length of the sleeve is shorter than that of the top of the container and in which the side walls of the container and also the edges of the circumferential flange 119 almost completely run straight across the length B, that of the width

the envelope is spanned. As before, there extend from the side walls 106 of the shell separate (not visible) Holding tongues up between the peripheral flange 119 and the body part of the container 118..

The closure lid of the container 119 has a central wall 120 which extends under the upper edge 121 of the closure lid is deepened, from which edge the peripheral flange 119 extends downwards. Essentially vertical Side walls 122 connect the recessed wall 120 to the edge 121. Extension tabs 123 that extend over fold lines connect to the top wall 105 of the sleeve, extend towards the recessed wall 120 and stand with it as well as with the substantially vertical ones Sidewalls 122 rubbing into contact. The rubbing touch of the extension straps not only supports the correct positioning of the 'casing in its predetermined position on the container, but also provides two surfaces, which can conveniently be gripped between a thumb and a finger of a hand to carry a package.

Figures 5 and 6 show a package comprising a single container with a substantially rectangular peripheral flange 219, with arcuate corners 225 as shown in Figure 5, where the top wall 205 of the shell is partially cut away is. The top wall 205 completely covers the top of the container, and each of the side walls 206 is with two upstanding retaining tongues are fitted between the downwardly directed peripheral flange 219 and the body of the container. The retaining tabs are provided with one end of each tab against the rounded corner of the peripheral flange comes to rest, with each tongue sliding the envelope relative to the container in opposite directions Directions. Since the top of the container has straight sides, the width of the over wall between / fold lines 202 and 203 corresponds essentially to the
