CA2060191A1 - Pallet container - Google Patents

Abstract

ABSTRACT OF THE DISCLOSURE
The invention relates to a large volume pallet container with base pallet (100), inner plastic container (12) and outer supporting casing (30). These pallet containers are usually very solidly built with stable heavy frame structures. An economical, lightweight construction with easily disposable individual components is desirable, particularly for non-returnable containers. To obtain a lightweight pallet container which nevertheless possesses the stiffness and strength needed to counteract the tendency to bulge when filled, the invention proposes that the upper rim of the thin-walled plastic inner container (12) be interlocked with the pulp casing, which consists of rolled kraft paper, by means of an overlapping flanged ring (46).
The bottom of the pulp casing (30) is inserted in a circular groove (74) in the surface of the plastic pallet (100) and is thereby mixed in the radial direction as well.

Claims (9)

Amended Claim (in the International Office on 10 October 1991 (10.10.91);
the original claims 1 to 7 replaced by amended claim 1;
claims 8 to 15 renumbered to be 7 to 14;
remaining claims unchanged)

1. A palette container with a lower palette, with an inner plastic container with a filler opening and a base removal valve arranged thereon and with an outer reinforcing casing that lies closely against the plastic container and encloses this, characterized in that the upper peripheral area of the plastic container (12) is connected by force and/or shaped fit with the upper edge of the reinforcing casing (14) and a yielding or flexing of the thin-walled container (12) in a radial direction outwards or inwards is prevented, and the lower edge (76) of the reinforcing material (14) is inserted into a circular groove (74 that is formed in the surface of the palette (10), and is in a similar way configured so as to be fixed in a radial direction.

2. Pallet container according to claim 1, wherein the upper peripheral area (44) of the plastic container (12) bears a vertically erect, peripheral flange ring (82) which extends axially and is fastened, for example by means of screws (94) or rivets, to the inner wall or upper edge (50) of the reinforcing jacket (30, 14) (Fig. 8).

3. Pallet container according to one of the foregoing claims 1 and 2, wherein the reinforcing jacket (14) is fastened to the pallet (10) by means of angular hooks (84) spread at equal intervals on the periphery, so that their upper hook part (86) fits into corresponding depressions (88) of the lower part of the cardboard jacket (30), or cover a transverse metal bar of the grid jacket (24), whereas their lower outer angles (90) are attached by appropriate fastening means such as screws (92) onto the upper surface of the pallet (10).

4. Pallet container according to one of the foregoing claims 1, 2 and 3, wherein the reinforcing jacket (14) is made in form of a grid jacket (24) with vertical and horizontal metal bars (Fig. 2).

5. Pallet container according to one of the foregoing claims 1 through 4, wherein the reinforcing jacket (14) consists of fibre tube or kraftliner made up of a number of kraft paper sheets wound and glued together (Fig. 3, 12, 13).

6. Pallet container according to claim 5, wherein the cardboard jacket (30) bears a number of windows (32) (for example, holes) located one above the other and serving for visually inspecting the level of material in the plastic container (12) (Fig. 3, 12, 13).

7. Pallet container according to one of the foregoing claims 1 through 6, wherein the comparatively thin-walled plastic container (12) and the superimposed reinforcing jacket (14), viewed in cross section, have on each straight side of the pallet (10) a sector (16) with straight walls (18) and in every corner area of the pallet (10), a sector (20) with circular walls (22).

8. Pallet container according to claim 7, wherein every sector (16) with straight walls (18) is less or equal to 45°, preferably between 35° and 10°, and every sector (20) with circular walls (22) is equal or larger than 45°, preferably between 55° and 80° (Fig. 1).

9. Pallet container according to one of the foregoing claims 1 through 6, wherein the comparatively thin-walled plastic container (12) and the superimposed reinforcing jacket (14), viewed in cross section, have on every straight side of the pallet (10) a sector (16') of ? 60° with walls bulging slightly outward (18'), and a sector (20') of ? 30° with comparatively strongly curved circular walls (22') (Fig. 13).
