Abstract

An outer sleeve 10 has an opening 14 with a latch 16 adjacent it. An inner container 20 provided with depression 24 can be slid into it. The outer container including the latches is formed of a resilient plastic sheet which can be folded 11, 13 and glued 12 into a tube having a lens shaped cross section. The latch operates by folding into the sleeves interior and engaging with the recess of the inner container. A weakened of perforated line 18 surrounds the latch to allow it to be torn off the rest of the sleeve and release the inner container. The sleeve may have an opening with an associated latch at each end and the container can have a corresponding recess at each end. Ideally one of the fold lines extends into both latches. Other cross sectional shapes such as tubular, square, oval, circular and rhombus are possible. Ideally the latches are rectangular extensions projecting from a rectangular net for the sleeve. There may be a notch 19 to assist location of the tear line 18.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. I is an isometric view of one embodiment of an outer box of a flexible plastic packaging box; and FIG. 2 is an isometric view of an inner box of the flexible plastic packaging box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Many aspects of the disclosure can be better understood in the following embodiments with reference to the accompanying drawings.

Referring to FIGS. 1 and 2, an embodiment of a flexible plastic packaging box includes an outer box 10 and an inner box 20.

The outer box 10 is a substantially spindle-shaped hollow body. In the illustrated embodiment, a flexible plastic sheet is bent to a substantially spindle-shaped hollow body and forms a first bending portion 11, and then opposite ends of the flexible plastic sheet are adhered to each other and cooperatively form an adhesion portion 12 and a second bending portion 13 opposite to the first bending portion lit the outer box 10 is finally made by the flexible plastic sheet. It should be pointed out that the outer box 10 may be integrally molded instead. The outer box 10 defines a cavity (not labeled) with a first opening 14 and a second opening 15 defining in opposite ends of the outer box 10. The cavity is configured to receive the inner box 20.

The outer box 10 further includes a first latching sheet 16 and a second latching sheet 17. The first latching sheet 16 and the second latching sheet 17 may bend to be received in the cavity. The first latching sheet 16 is adjacent to the first opening 14, and the second latching sheet 17 is adjacent to the second opening 15. In the illustrated embodiment, the first latching sheet 16 is substantially rectangular and extends from an edge of the first opening 14, the second latching sheet 17 is substantially rectangular and extends from an edge of the second opening 15, the first latching sheet 16 and the second latching sheet 17 are adjacent to the first bending portion 11.

It is to be understood that the first latching sheet 16 and the second latching sheet 17 can be used singly, fixed in the first opening 14 or the second opening 15 respectively.

The outer box 10 defines a tear line 18 and an indentation 19. The tear line 18 is located surrounding the first latching sheet 16 and extends from the first opening 14. The indentation 19 is defined in an end of the tear line 18 adjacent to the first opening 14.

The inner box 20 defines a first latching depression 22 and a second opening 24.

The first latching sheet 16 and the second latching sheet 17 are latched in the first latching depression 22 and the second latching depression 24 respectively. In the illustrated embodiment, the inner box 20 is made by bending a flexible sheet, and opposite ends of the flexible sheet abuts each other to form substantially a spindle-shaped tube.

To assemble the flexible plastic box 100, the inner box 20 is inserted into the cavity, the first latching sheet 16 is bent to be received in the cavity and latched in the first latching depression 22. The second latching sheet 17 is bent to be received in the cavity and latched in the second latching depression 24, such that the inner box 20 is securely received in the cavity of the outer box 10.

When the inner box 20 is to be detached from the out box 10, the outer box 10 is torn open along the tear line 18 to release the first latching sheet 16 from the outer box 10 and the first latching depression 22, then the inner box 20 may be taken out of the out box 10 from the first opening 14. Therefore, The flexible plastic packaging box may be easily assembled and disassembled.

It should be pointed out that cross-section of the outer box 10 is not limited to be substantially spindle-shaped, may be substantially circular, square, oval, or rhombus. The number of first latching sheets 16 and the number of second latching sheets 17 are all not limited to be only one, can also be more than one, correspondingly numbers of the first latching depression 22 and the second latching depression 24 are changed.

Furthermore, the outer box 10 may only define a first opening 14 on an end of the outer box 10, the other end of the outer box 10 may be obturated, correspondingly, the inner box 20 may only define the first latching depression 22.

It should be emphasized that the above-described embodiments of the present invention, particularly, any preferred embodiments, are merely possible examples of implementations, merely set forth for a clear understanding of the principles of the invention.

Many variations and modifications may be made to the above-described embodiment(s) of the invention without departing substantially from the spirit and principles of the invention.

All such modifications and variations are intended to be included herein within the scope of this disclosure and the present invention and protected by the following claims.
