The present invention relates to a packaging blank and a package.

More specifically, the invention relates to blanks according to the preamble of the appended claims 5 and 7 as well as blanks according to the preamble of claims 2 and 8.

U.S. Pat. No. 3,770,185 discloses the use of a blank consisting of, for example, hardboard coated on both sides with paraffin or polyethylene to form a unitary beverage-containing or pull-on bottle with a brush cover that encloses a whistle device. forming a tear strip. The tear strip is formed by two different groove lines on the outer surface of the wall forming the ridge cover, and the whistle 15 is formed by a closed loop-shaped groove line formed on the inner surface of the same wall below the different groove lines and in the pile. The groove lines are cut to a substantially overlapping depth (namely, 40-75% of the wall thickness) on opposite sides of the wall forming the ridge cover 20. The divergent groove lines extend from the yia edge of the sealing rib of the closure, initially close to each other and then parallel across one of the sealing sub-panels of the brush cover closure directly to one of the inner, blocking sub-panels of the closure. The adjacent portions of the different groove lines are substantially tangential to the end portions in a curved recess formed at the opposite edge of the sealing sub-panel, which recess facilitates the consumer to grip the tear strip 30. The purpose of this structure is that when the tear strip is drawn, the silky layer of material of the groove lines with different lines separates from the end wall together with the entire thickness of the wall inside the groove line forming the closed loop.

35 However, the strip does not tear reliably as intended. The first reason is that it depends on the tearing of the hard cardboard coating at the bottom of the curved recess, which may not happen. Another reason is that the shape of the recess attaches more strongly and supports the re-expansion strip of the parenun at its edges than its center, whereby it tears from the center of the parenun rather than from the edges from which it is to be torn. The third reason is that although the different groove lines extend to the edge of the rib, such a feature does not indicate very well to the consumer where the rib should be gripped and does not form a very good start to the tearing operation.

According to a first aspect of the present invention, there is provided a blank for forming a fluid-containing blank and having a whistle hole at the edge of said blank which encapsulates a re-strip of strip bounded by two slit lines extending at said edge. across one region of said blank, which is the outer surface of said carton but not the other surface thereof, wherein in the abutment of said two slit lines there is a 20 slit loop penetrating the second surface 13-pi of said second surface, although not the surface of said one surface. , and a third incision line extending adjacent the edge of said edge region blank from the region of said incision line of said two incision lines to the region of the second incision line, penetrating said second surface but not said one surface.

According to another aspect of the invention, there is provided a fluid-containing article formed of a sheet material having a whistle-30 perforated strip in the edge region which encapsulates a tear strip bounded by two slit lines extending across said edge region and tunk the outer surface of the sheet material, but not the inner surface of the sheet, wherein said two slit lines comprise a loop of 35 slits penetrating said second surface, although not said single surface, and a third 3 91232 slit extending near the edge of said edge region adjacent said two incision lines from the region of one incision line to the region of the other incision line, penetrating through said inner surface but not through said outer surface.

These two aspects of the invention promote the proper tearing of the material itself, especially at the beginning of the tearing of the tear strip material.

According to a third aspect of the present invention, there is provided a blank for forming a fluid-containing TOlk having a tear strip formed in its first edge region and bounded by two lines of weakness extending transversely to said edge region. A recess in the blank edge of the region to be sealed against said first edge region, the inner boundary of said recess being a straight line extending along said second edge region, the dimensions of said recess along said second edge region and the si-20 position is such that it extends in a closed column from at least one corresponding area of said lines of weakness to another.

According to a fourth aspect of the present invention, there is provided a fluid-containing case formed of a sheet material having a tear strip formed in a first edge region of a tongue bounded by two lines of weakness extending transversely to said edge region; a recess in the blank edge sealed against said first edge region, the first and second edge regions being directed outwardly in the same direction, the inner boundary of said recess being a straight line extending along said second edge region, and said at least one recess 35 from one corresponding area to another of said lines of attenuation.

Two aspects of the invention of the invention also promote proper tearing, in particular tearing of the tear strip across its entire width.

In order that the invention may be clearly understood and implemented, reference will now be made, by way of example, to the accompanying drawings.

Figure 1 shows a plan view of the outer surface of the paperboard in a blank intended to form a liquid-containing bend.

Figure 2 shows a plan view of the inner surface of the blank board.

Figure 3 shows a perspective view of the folds on one side.

Figure 4 shows a vertical view of the folds on the other side.

With reference to the drawings, the blank 1 is intended to produce a brush-covered folding label containing, for example, milk or orange juice. The blank consists of cardboard, each side of which is coated on each with a permeable layer of thermoplastic. The blank has four and groove lines 2 which divide the blank into five panels 11-15, of which panel 15 is an angle sealing panel. The groove lines 3 perpendicular to the groove lines 2 divide the row formed by the panels 11-15 into a row of flat bottom bracket cups 21-25, a row of paddle panels 31-35, a row of blocking yias closure panels 41-45 and a row of sealing panels 51. Other score lines 4 take care that the packaging machine can be folded in a flat ridge of the alasulun and yiasulun and consumer 30 can be folded out yiasulun ridge of the nose. Alternatively, the consumer may use a whistle blower instead of a cam, which is in the region of the edge of the tdlk. This device encloses a tear strip 5 which is in the middle of the sub-panels 42 and 52 and which is bounded by two slit lines 6 extending into the groove lines 3 across the sub-panel 52 into the sub-panel 42. The slit lines 6 penetrate the outer surface of the blank board. through the plastic layer, but their penetration ends close to the plastic layer that forms the inner surface of the blank board. A circular incision 7 is formed in the inner surface of the paperboard of the sub-panel 42. It penetrates through the plastic layer of the inner surface of the paperboard 5, but ends close to the plastic layer of the outer surface of the paperboard. It is located between lines 6. Two notches 8 are formed in the free edge of the sub-panel 52, leading to lines 6. At the bottom of the notches 8 there is a third notch line 9 extending from one notch to another along the lines 3, i.e. across the width of the tear strip 5. This line 9 penetrates through the plastic layer of the inner surface of the board, but ends close to the plastic layer of the outer surface of the board. The 8 sides of the Kum-mank notch are polished. In the middle of the free edge 15 of the sub-panel 54, a recess 10 is formed, the sides of which are rounded corresponding to the outer sides of the notches 8 and the bottom of which is straight and parallel to the line 9.

After the TOlk bottom closure is folded as well as heat and pressure sealed, filled with liquid, and its top-20 closure is folded as well as heat and pressure sealed, its shape is as shown in Figures 3 and 4. Tålldin is a line 9 at the height of the bottom of the recess 10 and the curved sides of the recess 10 are aligned with respect to the curved outer sides of the notches 8. Therefore, when the consumer grips the strip 5 protruding above the bottom of the recess 10 and pulls a part thereof away from the sealing rib 51-55, the line 9 and the fact that the whole part of the strip 5 above the line 9 remains unsealed with respect to the sub-panel 54 that the tearing of the strip 5 begins along the entire width of the strip 30 5 in the middle of the carton of the strip 5 at the height of the line 9. As the pulling of the strip 5 is continued, the cardboard tears down the entire width of the strip 5 between the lines 6 until the plug of material surrounded by the circle 7 is pulled out with the strip 5, so that a whistle hole is formed in the sub-panel 35 42.
