Container with improved stability and pour spout

Abstract

A drinking device having a conical frustum shaped body sealed at its bottom, a foldable spout and an inward partial closure. The drinking device is preferably bio-degradable and its spout is re-sealable. The drinking device may also have protrusions for standing.

Claims

1. A reclosable container with a spout, comprising: a body in a conical frustum shape with a closed bottom and an open top; a first portion of an upper end of the conical frustum folded inward along a curved spout crease to partially but not completely close an upper end of the conical frustum and to form reinforcing arcs supporting a spout opposite the curved spout crease; wherein the spout is folded along a curved closing crease opposite the curved spout crease and sealed to completely close the upper end of the conical frustum, a tip of the spout extending beyond a side of the container body near the spout crease.

2. The recloseable container of claim 1, wherein the conical frustum shape tapers so that a circumference of the closed bottom is greater than a circumference near the open top.

3. The recloseable container of claim 1 wherein the body is formed of paperboard.

4. The recloseable container of claim 1, filled with a liquid material.

5. The recloseable container of claim 1, filled with a pourable solid material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(10) Referring to the Figures, wherein like numerals indicate like or corresponding features or parts throughout the several views the improved container is described. Referring to FIG. 1 shows the inside plan view of the stock material, which may be common milk carton material such as 300-330 gsm poly coated SBS paperboard or similar material 13. Also, shown in FIG. 1 are the fold lines required to manufacture the embodiment with integral body and top seal after the material has been folded into the preferred conical shape and sealed along the overlapping edges 6 (Ref. FIG. 3). Dashed line 1-1 indicates the first inward fold lines, 2-2 indicates the second inward fold line.

(11) Referring to FIG. 2 which shows the plan exterior view 14 of the stock material 13 showing the over-lapping side seal areas 6 and the optional fold line 4 for the integral, Pull Tab. Also shown is the area for the seal 5 to the bottom component (not shown), and the relative position of not less than three optional protrusions 3 for enhanced stability.

(12) Referring to FIG. 3 the front view having been formed from the stock material 13 into a conical frustum and sealed along the side 6 and FIG. 4 the side view of the same conical form showing the curved profile angle A.

(13) Referring to FIGS. 5 and 6 the container is shown after the first inward fold (1-1) has been completed (Ref. FIG. 1). FIG. 5 is a section view of the view shown in FIG. 6 and includes a sectioned view of one of many possible bottom closures commonly known in the art 10.

(14) Referring to FIG. 7. FIG. 7 is a partial enlarged oblique downward detailed view of the container after the first inward fold (1-1) has been completed (Ref. FIG. 1). In this view the pour spout area 9 is shown. Also shown are the areas where the material of the first fold is sealed 8 to the stock material 13.

(15) Referring to FIGS. 8 and 9 the container is shown after the second inward fold (2-2) has been completed. The fold is also sealed to the stock material 13.
