Expandable document bag
An expandable document bag comprises a boxing casing; the box casing having a lower plate; a left lateral plate and a right lateral plate; an interior of the box casing being formed with a receiving space; each of the left lateral plate and right lateral plate having an inserting post; the lower plate being elastic; and the lower plate having two sliding slots at positions corresponding to the two inserting posts, each sliding slot being capable of receiving a respective inserting post; the inserting posts being slidable within the sliding slots. The lower plate is elastic and thus is expandable so as to adjust a size of the receiving space. The box casing is installed with at least one receiving bag for receiving documents or other objects.
The present invention relates to document bags, and particular to a expandable document bag, wherein by the interactions of the sliding slots of the lower plate and the inserting posts of the right lateral plate and left lateral plate, the space of the box casing is expandable and reducible. Thus the documents are restored in a proper space.
BACKGROUND OF THE INVENTIONIn the prior art, the document receiving bag is mainly made by plastic material. The bag is a box with an upper cover. The left, right and lower surfaces of the box are bent and are elastic. When more documents are received within the box casing, the front and rear sides of the box casing will expand for receiving more documents, and then the upper cover covers upon an opening of the bag.
The prior art expands for receiving more objects therein by expanding bending portions thereof. Thus, the expansion extent is finite. If too many documents are received, the bag will deform. If the bag is in a deforming state, it will be destroyed. Maybe the user carries more document bags to receive more documents, but this will increase the cost and make inconvenience to the users.
SUMMARY OF THE INVENTIONAccordingly, the primary object of the present invention is to provide an expandable document bag, wherein by the interactions of the sliding slots of the lower plate and the inserting posts of the right lateral plate and left lateral plate, the space of the box casing is expandable and reducible. Thus the documents are restored in a proper space.
To achieve above objects, the present invention provides an expandable document bag. The expandable document bag comprises a boxing casing; the box casing having a lower plate; a left lateral plate and a right lateral plate; an interior of the box casing being formed with a receiving space; each of the left lateral plate and right lateral plate having an inserting post; the lower plate being elastic; and the lower plate having two sliding slots at positions corresponding to the two inserting posts, each sliding slot being capable of receiving a respective inserting post; the inserting posts being slidable within the sliding slots. The lower plate is elastic and thus is expandable so as to adjust a size of the receiving space. The box casing is installed with at least one receiving bag for receiving documents or other objects.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
BRIEF DESCRIPTION OF THE DRAWINGS
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
The present invention is related to an expandable document bag, wherein the expandable document bag comprises a box casing 1. The box casing 1 is formed by a bottom plate 10, an upper cover 11, a left lateral plate 12, a right lateral plate 13 and a lower plate 14. The upper cover 11, left lateral plate 12 and right lateral plate 13 are connected by a slightly compressible bending portion 15 and the bottom plate 10. Each of the left lateral plate 12 and the right lateral plate 13 has one inserting post 16 thereon.
The lower cover 14 is formed with two sliding slots 17 corresponding to the two inserting posts 16. A plurality of receiving bags 18 are formed on the bottom plate 10 at an inner side of the box casing 1. The receiving bags 18 serves to receiving smaller documents and related materials. By opening and closing the box casing 1 by using upper cover 11, objects in the receiving bags can be taken out.
Referencing to
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
Claims
