摘要:
A hanging storage system comprising a resealable evacuable bag and a hanging device attached to the bag. The hanging device is designed to attach to a portion of the bag in a manner such that a vacuum inside the evacuated bag can be maintained while the bag is hanging, e.g., in a closet. More specifically, the hanging device comprises first and second parts that couple together, the first part being disposed inside the bag and the second part being disposed outside the bag, with a portion of a thin flexible bag wall being disposed between the coupled first and second parts.
摘要:
A method of inflating a dunnage bag in a box including the steps of inflating the dunnage bag; with one or more sensors, monitoring deflection of at least two surfaces of the box while inflating the dunnage bag; upon detecting through monitoring that deflection of either of at least two surfaces reaches a corresponding preseleted threshold, automatically terminating inflating of the box.
摘要:
There is described an improved inflatable package comprising outer deformable walls defining at least one fluid-tight chamber therebetween, and a one-way valve disposed within the chamber, to be in fluid communication therewith, the valve permitting the ingress of fluid into the chamber, and preventing the egress of fluid therefrom, the valve including a primary duct and at least one flow channel intersecting the primary duct at an angle to place the primary duct in fluid communication with the interior of the chamber.
摘要:
A water container comprises a bag body formed of a flexible material and a stopper means formed of a synthetic thin resin film. The stopper means is in the tubular form provided with a water inlet opening and a valve opening as well as a belt-like sealing on a portion except for the openings, and is attached into the bag body in such a manner that the inlet opening is open on the bag body and other portion is located within the bag body.The valve opening is smaller in size than the inlet opening, and is positioned on a line extending from at least a portion of the sealing.
摘要:
A valve bag having an upper bottom with a valve and a lower bottom symmetrically folded in a manner where the bottoms lie atop the central bag portion in a side-by-side and parallel manner is provided.
摘要:
A bag of tubular form comprising at least two plies of molecularly oriented plastic film, laminated together with their directions of orientation angularly disposed to each other and to the longitudinal direction thereof, said bag having at each end thereof one surface overlapping an oppositely disposed surface, a pair of oppositely disposed gussets interposed between said surfaces, said gussets extending at said bag ends into the overlap areas between said oppositely disposed surfaces, at least one bag end including all of said overlapping portions being folded over and adhered to the oppositely disposed surface, the bag in the preferred embodiment being closed at both ends and being provided with a valve sleeve for filling.
摘要:
A blasting shot hole stemming bag to be filled with a noncompressible fluid and having a self-closing valve. The valve is formed of overlying strips of vinyl heat sealed along predetermined lines to provide a narrowed valve passage. The bag is fabricated of different thickness or different degrees of flexibility of the plastic vinyl or similar material and has heat seal lines forming the permanently closed end as well as the narrowed filler valve between the bag side walls, and additional heat seal lines restricting the bag top to a small mouth leading to the valve, the valve and valve passage being located within the bag and spaced substantially from the bag mouth to prevent objects from contacting the valve and accidentally opening it. By fabricating the bags so that opposite sides are of the material having the different degrees of flexibility, when filled with the fluid the more flexible bag side is pulled to a greater degree both longitudinally and laterally being evidenced by a pronounced direction of the side and end seams, with the attendant advantage that the bag material at the valve end of the bag is pulled downwardly in a very positive manner to provide a protective shield for the valve to preclude inadvertant opening of the valve during tamping into the shot hole. The bag material is further possessed of a stretchable characteristic enabling the bags to be elongated to reduce their cross-sectional dimension to facilitate their being placed into irregular size shot holes which may result from use of worn drill bits. Multiple bags, each with its valve, may be simultaneously formed by overlying suitable plastic strips and sheets, and forming heat seals along predetermined lines. Individual bags may be torn from the composite sheet by tearing along certain heat seal lines.
