An article (600) is provided which includes a body (500) having an interior volume (100), and hook (124) and loop (125) features which, when pressed closed in at least one locations (130, 131) location, creates a dynamic hammock dam (132) that retains a fill material (140) that has been inserted int
An article (600) is provided which includes a body (500) having an interior volume (100), and hook (124) and loop (125) features which, when pressed closed in at least one locations (130, 131) location, creates a dynamic hammock dam (132) that retains a fill material (140) that has been inserted into the interior volume. The strength of the hammock dam increases with outward pressure (141) applied on the closure by the fill material. The article is preferably equipped with a large mouth opening (110) which allows rapid filling or emptying of the fill material from the internal volume.

1. An article, comprising: a body having first and second opposing walls and housing an interior volume;a particulate filler disposed in said interior volume;a dam disposed on an interior surface of said first wall; anda releasable fastener having a first component disposed on a first surface of said dam, and a second component disposed on an interior surface of said second wall opposing said dam; wherein said article is transformable between a first state in which said first and second components of said releasable fastener are spaced apart from each other such that said interior volume is in open communication with the environment external to the article by way of a channel which terminates in an external opening, and a second state in which said first and second components of said releasable fastener are releasably engaged to each other such that said interior volume is closed off from the environment external to said body, wherein said first and second opposing walls are adjoined to each other along a peripheral seam, and wherein said first component of said releasable fastener includes a first portion disposed on said first surface of said dam, and a second portion disposed in said channel adjacent to said external opening. 2. The article of claim 1, wherein said article is transformable between said first and second states by applying force in a direction perpendicular to said first surface of said dam. 3. The article of claim 1, wherein said releasable fastener is a hook-and-loop fastener. 4. The article of claim 1, wherein said channel has a longitudinal axis, and wherein said first surface of said dam extends along said longitudinal axis. 5. The article of claim 4, wherein said dam forms a region that is open on a single side which faces away from said opening to the external environment. 6. The article of claim 5, wherein the dynamic internal pressure from the fill material increases the bond between the first and second components of the releasable fastener when the article is in the second state through shearing bond strength. 7. The article of claim 1, wherein said channel has a longitudinal axis, and wherein said dam is concave in the direction of a vector extending from said interior volume to said channel. 8. The article of claim 5, wherein said channel has a longitudinal axis, and wherein said dam is U-shaped in a cross-section taken in a plane containing said longitudinal axis and perpendicular to said first surface of said dam. 9. The article of claim 1, wherein said first and second portions of said first component of said releasable fastener releasably engage said second component of said releasable fastener when said article is in said second state. 10. The article of claim 1, further comprising a first protective rim which is disposed about the periphery of said first and second opposing walls. 11. The article of claim 1, further comprising a second protective rim which is disposed about the periphery of said opening. 12. The article of claim 1, wherein said article is an ellipsoid or a parallel-piped. 13. The article of claim 1, further comprising: a handle which extends from said body. 14. The article of claim 1, further comprising a portion of webbing which extends about a peripheral surface of said device. 15. The article of claim 1, wherein said article is a parallel-piped, and further comprising a portion of webbing which extends diagonally across a parallelogram on the surface of said device. 16. A method for creating a weighted article, comprising: providing an article having (a) first and second opposing walls and housing an interior volume, (b) a dam disposed on an interior surface of said first wall; and (c) a releasable fastener having a first component disposed on a first surface of said dam, and a second component disposed on an interior surface of said second wall opposing said dam, wherein said article is transformable between a first state in which said first and second components of said releasable fastener are spaced apart from each other such that said interior volume is in open communication with the environment external to the article by way of a channel which terminates in an external opening, and a second state in which said first and second components of said releasable fastener are releasably engaged to each other such that said interior volume is closed off from the environment external to said body, and wherein said first component of said releasable fastener includes a first portion disposed on said first surface of said dam, and a second portion disposed in said channel adjacent to said external opening;positioning the article in the first state;adding a particulate filler to the internal volume by way of the channel and opening; andtransforming the article to the second state. 17. The method of claim 16, wherein said first and second opposing walls are adjoined to each other along a peripheral seam. 18. An article, comprising: a body having first and second opposing walls and housing an interior volume;a particulate filler disposed in said interior volume;a dam disposed on an interior surface of said first wall; anda releasable fastener having a first component disposed on a first surface of said dam, and a second component disposed on an interior surface of said second wall opposing said dam; wherein said article is an ellipsoid and is transformable between a first state in which said first and second components of said releasable fastener are spaced apart from each other such that said interior volume is in open communication with the environment external to the article by way of a channel which terminates in an external opening, and a second state in which said first and second components of said releasable fastener are releasably engaged to each other such that said interior volume is closed off from the environment external to said body, wherein said first component of said releasable fastener includes a first portion disposed on said first surface of said dam, and a second portion disposed in said channel adjacent to said external opening. 19. The article of claim 18, wherein said first and second opposing walls are adjoined to each other along a peripheral seam. 20. The article of claim 18, wherein said channel has a longitudinal axis, wherein said first surface of said dam extends along said longitudinal axis, wherein said dam forms a region that is open on a single side which faces away from said opening to the external environment, and wherein said dam is U-shaped in a cross-section taken in a plane containing said longitudinal axis and perpendicular to said first surface of said dam.
