JPS58193248A - Paper box in which leaked powder is prevented - Google Patents

Abstract

A carton formed from board or a similar material, primarily intended for detergent powder. The carton is erected by folding from a blank, the particular feature being that powder tightness and efficient use of board are achieved by arranging for the closure to be formed by sandwiching a plain flap hinged to a side panel between a moulded flap, also hinged to a side panel and a moulded flap hinged to an end panel.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dust proof I paper box formed from paperboard or the like, and a spread material pattern for the dust leak proof 1F paper box.

DE 2260766 relates to a paper box in which one of the two flaps hinged to the sideboard is molded along the longitudinal section of the sideboard in close proximity to the hinge engagement line. It is.

The mold has to be made into a sealed part, so it is similar to deep drawing and has the disadvantage that the hardness of the paperboard makes it difficult to hold if it is made of paper. . 2 which is bent into this first flap which is said one flap;
In the area of the molding where two dustproof flaps are wasted, they must then be cut away. The outer flap is
The disadvantage is that the molding corresponding to the flap must be made in the opposite direction, which adds complexity to the process.

We have now achieved the above-mentioned West German published patent number 2 in terms of wet powder prevention.
It has now been discovered how to assemble a foldable powder-proof paper box that is at least equivalent to the wet-powder-proof +L paper box described in No. 260,766.

Accordingly, the present invention provides a powder-proof paper box having a powder-proof seal formed by two flaps which are at least partially overlapping and hinged to the side paperboard, and two powder-proof flaps. In this case, two flaps 12.13 hinged to one of the two side paperboards 2.3 are each attached to the pattern line 1.
4.15, dust-proof flaps 16.17 are each formed with the impression lines 20.21, and the remaining flaps 6.7 are respectively formed with said impression lines 14.20.15.
21 and between the flap 12 and the dustproof flap 16 and between the flap 13 and the dustproof flap 1.
To provide a paper box for preventing wet powder, which is characterized by the presence of 7 types of darkness.

Preferably, the marking line in one or two of the two flaps 12.13 hinged to said sideboard is such that the free end of said flap is aligned with the hinged end 61 of said flap.
(The molding line for the powder-proof flap 16.17, which is shaped like a bulge when viewed from above, is the shape of the swollen end of the flap 12.13.) The part of the flap that is directly below the powder protection I

Therefore, between said molding lines, dustproof flaps 16.1

! Sandwiching one of the unremoved flaps 6.7, 1. With respect to this arrangement, 1. Two flaps hinged to the side paperboard, 1. It is sufficient that the powder-proof flap is short enough to overlap only the minimum amount of powder. Additionally, the mold lines described above can be relatively easily added to a dust proof paper box pattern.

According to a further aspect of the invention, □ a dustproof flap is hingedly engaged to a corresponding endboard along the entire length of the corresponding endboard; Conveniently, it is obtained around the mold line. This offset ensures that the two flaps lie flat, one on top of the other and on the anti-powder flap between the fold line and the impression line.

In FIG. 1, reference numeral 1 denotes a pattern of the unfolded material for a folding and assembling wet powder-proof paper box according to the present invention. The unfolded material pattern for a fold-assembled wet powder-proof paper box has two side paperboards 2 and 3 and two end paperboards 4 and 5. At the top and bottom, the flap 6.7 is hinged to the sideboard 2 around the fold line 8.9. Around the fold line 10.11 two flaps 12.13 are hinged to the sideboard 3;
The flaps 12.13 are 5 along the mold line 14.15.
− Moulded. The outer portions of the flaps 12 and 13 that extend beyond the impression line 10 or 11 are impressiond in the rearward direction.

The two endboards 4 and 5 each have two dustproof flaps 16.
17, 26, and 27 are attached. These powder-proof flats 1 are connected through fold lines 18.1B and 28.2B 1) τ
It is hinged to the corresponding endboard. Regarding the fold lines, fold lines 18 and 28 are extensions of fold line 10, and fold lines 1 and 29 are extensions of fold line 11.

The above-mentioned fold lines 18, 19, 28, 29 each form a molding extending from the outer edge of the dust protection flap 16, 17, 26, 27 at right angles to the fold lines and in the center of the flap. It ends at line 20.2L30.31. These die lines 20.21.30.31 extend slightly beyond each fold line and are additional die lines extending in the same direction as each corresponding fold line but somewhat offset from each corresponding fold line. Continuing as 22.23.32.33. The end paperboard 5 is hinged with an adhesive flap 34 and can be connected to the side paperboard 2 by means of the adhesive flap 34.

FIG. 2 is a cross-sectional view through a fully assembled and sealed dust proof paper box according to the present invention. The cross section is cut perpendicularly through the two side paperboards 2 and 3. The seal of the powder-proof paper box according to the invention is formed as follows: The deepest overlap is formed by folding in the flaps 16, 17 at the top and bottom. Then the flaps 6 and 7 that are not molded are molded at the molding line 20.22
and 21.23 along with the deeper molded part of the anti-powder flap 16.17, lying on F. The depth of the impression is such that it accommodates approximately one-half the thickness of the un-embolded flap described above. The remaining flap 12.13 is then folded over the unshaped part of the dust protection flap 16.17. And the molded part along the molding line 14.15 is a flap 6.7 which is not molded.
-1 and rests on a somewhat unshaped flap 6.7.

A powder-proof 11-inch paper box according to the present invention, which is substantially prevented from getting wet powder, is assembled from the paper pattern of this design h1.
