TH23987U - Box for packaging liquids - Google Patents

Abstract

The liquid packaging box consists of an outer box body made of folded cardboard, forming a rectangular shape with side sections one, two, a front body, a back body, and a bottom support base. The liquid container is a transparent plastic bag with its top connected to a flap assembly. The flap is made of folded cardboard forming an isosceles trapezoid shape. Improvements have been made to the lower center edges of the four side walls of the flap, which are fitted into slots one, two, three, and four on the outer box body. This ensures a tight seal between the first, second, third, and fourth seams of the outer box body and the four side walls of the flap. Similarly, the four flaps of the flap are tightly sealed against the inner wall of the outer box body.

Claims (1)

1. The box for holding liquids consists of an outer body (1) made of a sheet of paper folded into a rectangular shape with side sections one (2), side section two (3), front body (4), and back body (5) joined together by a fold line (6). The bottom seams of side section one (2), side section two (3), front body (4), and back body (5) are joined together by a fold line (6) to the bottom support base. The top edge of side section one (2) is joined together by a fold line (6) to the first ridge (7), which is an isosceles trapezoid with its side edges tilted toward each other. The top edge of side section two (3) is joined together by a fold line (6) to the second ridge (10), which is an isosceles trapezoid with its side edges tilted toward each other. The upper edge of the anterior body section (4) is folded by a crease (6) to the third articulated section (12), which is an isosceles trapezoid with its side edges tilted inward. The upper edge of the posterior body section (5) is folded by a crease (6) to the fourth articulated section (14), which is an isosceles trapezoid with its side edges tilted inward. The lower middle of the first lateral section (2) is the first viewing window (16), and the lower middle of the second lateral section (3) is the second viewing window. The first viewing window (16) and the second viewing window are used to provide a view of the amount of liquid contained within the outer box body (1). The liquid bag (17) is installed on the inside top of the outer box body (1). The liquid bag (17) is a transparent plastic bag whose body size corresponds to the size of the outer box body (1), and the top of the liquid bag (17) is connected to the flap assembly (18). The flap assembly (18), with its side edges, is sealed to the center of the box cover (9). The box cover (9) is a sheet of paper folded into an isosceles trapezoid shape with four side walls (19) angled inward. The top edges of the four side walls (19) are folded together by a crease (20) with the top flap (21) which has a center area. It is a circular opening for fitting into the middle section of the lid assembly (18), with the following characteristics: the middle of the lower edge of the first interlocking section (7) is the first slot (8) for fitting into the box cover (9); the middle of the lower edge of the second interlocking section (10) is the second slot (11) for fitting into the box cover (9); the middle of the lower edge of the third interlocking section (12) is the third slot (13) for fitting into the box cover (9); the middle of the lower edge of the fourth interlocking section (14) is the fourth slot (15) for fitting into the box cover (9); the middle of the lower edge of the four side walls (19) of the box cover (9) is a flap (22) for fitting into the first slot (8), the second slot (11), the third slot (13), and the fourth slot (15) of the outer box body (1), where the contact surface between the first interlocking section (1) The second (10), third (12) and fourth (14) seams of the outer body of the box (1) and the four side walls (19) of the box cover (9) are tightly sealed together, and the contact surfaces between the four flaps (22) of the box cover (9) and the inner wall of the outer body of the box (1) are also tightly sealed together.
