Pouring element for a package and composite package having such a pouring element

Abstract

A pouring element for a package having a base body, a polyhedrally formed flange which is designed for joining to a package sleeve and whose joining faces converge in face abutments, as well as a pouring element for a package, in which the package sleeve is correspondingly joined to the pouring element. Provision is made for receiving areas to be formed in the area of the face abutments for the fold line of the package sleeve ears, in order to prevent the package from becoming damaged during the joining process between the pouring element and the package sleeve and during the folding of the package sleeve ears and hence keep it leak-tight.

A pouring element for a package comprising a base body, a polyhedrally formed flange which is designed for joining to a package sleeve, wherein joining faces of the flange converge in face abutments, wherein receiving areas are formed in an area of the face abutments for a fold line of package sleeve ears, wherein the receiving areas are formed as roundings of the face abutments, and wherein the receiving areas are further defined as a space between the roundings and the package sleeve ears that are configured to receive packaging sleeve material when the package sleeve ears are folded.

2. The pouring element according to claim 1, wherein wing-like material projections are formed in the area of the face abutments.

3. The pouring element according to claim 1, wherein at least one material rib is formed on the joining faces of the flange.

4. The pouring element according to claim 1, wherein the flange of the base body is in a shape of a truncated pyramid.

5. The pouring element according to claim 1, wherein the base body has a rectangular base plate.

6. The pouring element according to claim 5, wherein the base plate is square.

7. The pouring element according to claim 5, wherein the base plate forms an overlap locally with respect to the flange.

8. The pouring element according to claim 1, wherein the base body has a pouring neck.

9. The pouring element according to claim 8, wherein the pouring neck is initially sealed with a screw cap.

10. The pouring element according to claim 8, wherein the base body is closed below the pouring neck by means of a retaining wall and has a circumferential weakening zone.

11. The pouring element according to claim 10, wherein a barrier film abuts on the retaining wall.

12. The pouring element according to claim 10, wherein a handle is integrally formed on the retaining wall, so that the retaining wall can be removed by manually pulling on the handle.

13. The pouring element according to claim 10, wherein a cutting element is arranged in the pouring neck, so that the retaining wall can at least partly be cut open in an area of the weakening zone.

14. The pouring element according to claim 1, wherein the pouring element is a composite package for liquid foods with a polyhedrally formed gable area and the folded package sleeve ears, wherein the gable area can be correspondingly joined to the polyhedrally formed flange.

DESCRIPTION OF THE INVENTION

(11) FIG. 1 shows a preferred exemplary embodiment of a pouring element according to the invention in a perspective illustration at an angle from above. The pouring element in the illustrated and in this respect preferred exemplary embodiment has a base body 1 and a screw cap 2. The screw cap 2 fits on a pouring neck 3 (easily identifiable in FIG. 3A) which forms a part of the base body 1.

(12) The base body 1 has a circumferential, polyhedrally formed flange 4 as a truncated pyramid. The flange 4 and the pouring neck 3 project in opposing directions from a square base plate 5 of the base body 1 and together form the actual base body 1.

(13) FIG. 2 shows a complete composite package P according to the invention with a polyhedrally formed gable area 6, here in the shape of a truncated pyramid. When forming the top area, the pouring element is joined to the package sleeve and the gable area 6 is formed by corresponding folds. The package sleeve ears 7, which are produced when the tapered gable area 6 is formed and consist of “excess” package sleeve material, are folded down over a fold line 8 until they abut on the gable surfaces of the gable area 6 and can consequently be durably attached.

(14) The screw cap 2 is removed in the illustration in FIGS. 3A-3C, but it essentially corresponds to the one in FIG. 1. The polyhedrally formed flange 4 and in particular its joining surfaces 9 correspond to the gable surfaces of the polyhedrally formed gable area 6 of the composite package Pin shape and position. The join parts therefore lie parallel to one another. The joining surfaces 9 converge in face abutments 10; these correspond here to (imaginary) truncated pyramid edges. The joining surfaces 9 have material ribs 11 which strengthen the flange 4 mechanically and also provide sufficient material for the joining process.

(15) Wing-like material projections 12 are likewise integrally formed in the face abutments 10, so that sufficient material is provided at the desired place for the joining process. The additional material in particular improves the sealing of the upper section of the package sleeve ear 7.

(16) It can also be identified that the underside of the pouring neck 3 in its original state is sealed by a retaining wall 15. This is joined to the base body 1 via a weakening zone 16. A cutting element 22 at the bottom of a cutting ring 21 cuts through the weakening zone 16 when the screw cap is unscrewed for the first time and in this way exposes the opening for pouring through the pouring neck 3. In order to guarantee a sufficient shelf life and preserve the flavour of the filled product, a barrier film 19 is applied on the inside of the base plate 5 and retaining wall 15.

(17) FIG. 4 shows a partly complete composite package, in which the pouring element is already joined to the package sleeve, but in the gable area 6 the package sleeve ears 7 have still not been folded down over the fold lines 8. The forming fold line 8 is illustrated here as a prepared crease in the package sleeve.

(18) FIG. 5A shows a functional drawing of the folding process which can be seen in a horizontally cut detail view through the flange 4 and the package sleeve ears 7 in the area of the face abutments 10 of the joining surfaces 9. The face abutments 10 in the illustrated and in this respect preferred exemplary embodiment are formed as positive roundings 13 of the flange 4 and form between their periphery and the package sleeve a receiving area 14 for the fold line 8 of the package sleeve ear 7. The deformation movements of the folding around the fold line 8 are indicated by the movement arrows. The possibility of giving away and receiving package sleeve material in the area of the fold line 8 into the receiving area 14 results in lower mechanical loads and in this way prevents damage. As shown in FIG. 5B, the receiving areas 14 may also be formed as bevels 17 of the face abutments 10. As shown in FIG. 5C, the receiving areas 14 may also be formed as pockets 18 of the face abutments 10.
