Abstract

A stackable, collapsible container for flowable materials. The container utilizes an outer container and a flexible inner liner retained by a base, a top and a plurality of support poles. The support poles are retained in a plurality of holes in the base provided with a plurality of wedges to secure the holes against lateral movement. Providing wedges within tapered holes facilitates the compression molding of the depth of holes required for adequately supporting the support poles.

Claims

1. A pole securement system comprising:

(a) a receiver comprising;

(i) a main wall facing a cavity having a bottom, a top, a depth and a width, wherein said depth of said cavity is at least twice as long as said width of said cavity;

(ii) a first sidewall coupled to said main wall, wherein said first sidewall is wider near said top of said cavity than near said bottom of said cavity;

(iii) a second sidewall coupled to said main wall, wherein said second sidewall is wider near said top of said cavity than near bottom of said cavity;

(b) a pole provided within said cavity, wherein said pole is in contact with said main wall, wherein said pole is not in contact with said first sidewall and wherein said pole is not in contact with said second sidewall.

2. The stackable collapsible container of claim 1, wherein said main wall is between three millimeters and thirty millimeters thick.

3. The stackable collapsible container of claim 1, wherein said first sidewall is secured to said main wall at an angle between forty-five and one hundred degrees.

4. The stackable collapsible container of claim 1, further comprising:

(a) a wall face facing said cavity;

(b) a third sidewall coupled to said wall face, wherein said third sidewall is wider near said top of said cavity than near said bottom of said cavity; and

(c) a fourth sidewall coupled to said wall face, wherein said fourth sidewall is wider near said top of said cavity than near said bottom of said cavity.

5. The stackable collapsible container of claim 1, further comprising a pallet provided around said receiver.

6. The stackable collapsible container of claim 5, further comprising a supplemental receiver provided in said pallet, said supplemental receiver comprising:

(a) a second main wall facing a second cavity, having a bottom, a top, a depth and a width wherein said depth of said second cavity is at least twice as long as said width of said second cavity;

(b) a third sidewall coupled to said second main wall, wherein said third sidewall is wider near said top of said second cavity than near said bottom; and

(c) a fourth sidewall coupled to said second main wall, wherein said fourth sidewall is wider near said top of said second cavity than near said bottom.

7. A pole securement system comprising:

(a) a wall defining a cavity;

(b) a first wedge coupled to said wall;

(c) a second wedge coupled to said wall;

(d) a pole provided within said cavity; and

(e) wherein said pole is in contact with said first wedge and said second wedge.

8. The pole securement system of claim 7, wherein said first wedge and said second wedge taper toward a bottom of said cavity.

9. The pole securement system of claim 7, wherein said first wedge is secured to said wall along a first distance and extends toward an axial center of said cavity a second distance, wherein said first distance is greater than said second distance.

10. The pole securement system of claim 9, wherein said first distance is at least twice as great as said second distance.

11. The pole securement system of claim 7, wherein said first distance is greater than a diameter of said cavity.

12. The pole securement system of claim 7, further comprising a third wedge coupled to said wall and a fourth wedge coupled to said wall.

13. The pole securement system of claim 7, further comprising a buttress coupled to an exterior surface of said wall.

14. The pole securement system of claim 7, further comprising a base coupled to said wall, wherein said base defines a drain.

15. The pole securement system of claim 7, further comprising a pallet coupled to said wall.

16. A storage system comprising:

(a) a pallet defining a hole having a wall;

(b) a first wedge coupled to said wall;

(c) a second wedge coupled to said wall; and

(d) a pole releasably secured at least partially within said hole by said first wedge and said second wedge.

17. The storage system of claim 16, wherein said hole is at least five centimeters deep and less than fifty centimeters deep.

18. The storage system of claim 16, wherein said hole has a diameter and a depth, wherein said diameter is less than said depth.

19. The storage system of claim 16, further comprising a buttress coupled to said wall on an exterior portion of said wall opposite said first wedge.

20. The storage system of claim 16, further comprising a flexible bag secured on said pallet, the flexible bag having a capacity of at least one hundred liters.
