A 3D storage bag includes opposing flexible plastic front and back panels, the two opposite lateral sides of each of the flexible plastic front and back panels each having a first segment and second and third segments respectively extended from the top and bottom ends of the first segment, the first segments of the two opposite lateral sides of the flexible plastic front and back panels being respectively sealed together, a flexible plastic top panel bonded to the flexible plastic back panel and the second segments of the two opposite lateral sides of the flexible plastic front and back panels and defining with the flexible plastic front panel an opening, a flexible plastic bottom panel bonded to the bottom sides of the flexible plastic front and back panels and the third segments of their two opposite lateral sides of the flexible plastic front and back panels, and a fastening tape for closing/opening the opening.
(a) Field of the Invention
The present invention relates to storage bags and more particularly, to a 3D storage bag, which has a 3-dimensional storage chamber defined therein for storing big storage items.
(b) Description of the Prior Art:
Collapsible storage bags may be used in houses for storing clothes, quilt and other storage items. People may use a collapsible storage bag for carrying clothes while traveling. Further, a collapsible storage bag may be provided with an exhaust valve so that a vacuum cleaner or air-suction apparatus can be used to draw air out of the collapsible storage bag, reducing the storage size and facilitating carrying or long period storage. Commercial inexpensive collapsible storage bags commonly comprise a bag body made by sealing two rectangular flexible plastic sheet members together, and a fastening tap bonded to the bag body for closing/opening an opening in one side of the bag body. The storage space defined in the bag body is a narrow space, not convenient for arrangement of storage items. This narrow space has a limited dimensional, not practical for storing big storage items, such as heavy coat or quilt.
SUMMARY OF THE INVENTIONThe present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a 3D storage bag, which is made by a flexible plastic sheet material and defining therein a three-dimensional storage space for storing storage items and provided with a fastening tape for closing/opening an opening thereof and an exhaust valve for exhaust of internal air to keep the storage items in a substantially vacuum status, maintaining the quality of storage items.
To achieve this and other objects of the present invention, a 3D storage bag comprises opposing flexible plastic front panel and flexible plastic back panel each having a top side, a bottom side and two opposite lateral sides, the two opposite lateral sides of each of the flexible plastic front panel and flexible plastic back panel each having a first segment, a second segment extended from a top end of the first segment and a third segment extended from a bottom end of the first segment, the first segments of the two opposite lateral sides of the flexible plastic front panel and the flexible plastic back panel being respectively sealed together; a flexible plastic top panel having three of four sides thereof respectively bonded to a top side of the flexible plastic back panel and the second segments of the two opposite lateral sides of the flexible plastic front panel and flexible plastic back panel and the other one of the four sides in proximity to and spaced from the top side of the flexible plastic front panel by an opening; a flexible plastic bottom panel having four sides thereof respectively bonded to the bottom sides of the flexible plastic front panel and the flexible plastic back panel and the third segments of the two opposite lateral sides of the flexible plastic front panel and the flexible plastic back panel; a fastening tape adapted for closing/opening the opening between the flexible plastic front panel and the flexible plastic top panel, the fastening tape comprising a male fastening tape member fixedly fastened to an inner face of the flexible plastic top panel and a female fastening tape member fixedly to an inner face of the flexible plastic front panel and fastenable with the male fastening tape; and an exhaust valve bonded to the flexible plastic front panel and adapted for exhaust of air out of the 3D storage bag.
Thus, subject to the aforesaid arrangement, the flexible plastic front panel, the flexible plastic back panel, the flexible plastic top panel, the flexible plastic bottom panel, the fastening tape and the exhaust valve are assembled together, forming a 3D storage bag having a predetermined length, width and height for storing storage items in a good order, facilitating access to storage items.
Further, a vacuum cleaner or air-suction apparatus may be used and attached to the exhaust valve to draw air out of the 3D storage bag, keeping storage items in a vacuum status. Further, a hanger may be bonded to the 3D storage bag for hanging storage items inside the 3D storage bag and hanging the 3D storage bag on a support.
Referring to
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
