Definitions

the present invention relates to an envelope for packaging products, in particular foodstuffs such as for example portions of processed cheese, this envelope comprising a precut sheet of tearable packaging material and a tear-off member comprising a tongue. free and a tear strip welded to the sheet of packaging material to allow to tear the latter along the outer edge of this strip.
It also relates to a method of manufacturing an envelope for packaging products, in particular foodstuffs such as for example portions of processed cheese, this method consisting in equipping a precut sheet with tearable packaging material, a tear-off member comprising a free tongue and a tear-off strip welded to the sheet of packaging material.
the packaging of certain products is usually carried out by means of a sheet of tearable packaging material such as heat-sealable aluminum fitted with a tear strip welded to the surface of the packaging material and provided with a free tab enabling the strip to be grasped and to initiate the tearing of the material.
a sheet of tearable packaging material such as heat-sealable aluminum fitted with a tear strip welded to the surface of the packaging material and provided with a free tab enabling the strip to be grasped and to initiate the tearing of the material.
the present invention proposes to overcome these drawbacks by producing an envelope provided with a tear-off member allowing the complete opening of the envelope on two of its sides, the cutting of this tear-off member being carried out without falls, and its installation can be carried out in an extremely simple manner.
the envelope according to the invention is characterized in that the tear strip consists of a V-shaped element cut from a piece in a strip of a first material resistant to tearing, this element being welded over its entire length, to the inner surface of the packaging material, and in that the free tongue is constituted by an end section of a rectilinear tab cut from a strip of a second tear-resistant material, this tab being arranged so that one of its longitudinal edges coincides with the axis of the V-shaped element formed by the tear strip and that its two ends are positioned on either side of a branches of the V-shaped element, the free tongue of the tearing member being constituted by an end section of the tab disposed outside the V, and projecting beyond the edge of the precut sheet, at at least two welding points being provided respectively on either side of this branch to fix the tab on the inner surface of the packaging material.
the two branches of the V-shaped element are arranged flat on one side of the packaged product along two edges of this product.
These two branches each have a free end section, bent at a right angle, the point of the V-shaped element being placed flat on one side of the product to be packaged, along two edges of this product, and the two bent sections being arranged on one or two faces of the product, perpendicular to the first face, along two edges of this product.
the tear strip is arranged in such a way that the V-shaped element is welded to the inner surface of the one of the square faces, along two adjacent sides of this square, and that the rectilinear tab has an edge aligned on the diagonal of this square passing through the tip of the V-shaped element
the tear strip is arranged in such a way that the V-shaped element is welded to the interior surface of one of the triangular faces, the along two of its sides, and that the rectilinear tab has an edge aligned with the bisector of the angle formed by the V-shaped element
the first tear-resistant material and the second tear-resistant material are different in nature.
the method of manufacturing such an envelope is characterized in that a V-shaped element is cut from a strip of a first tear-resistant material which is welded over its entire length to the sheet of material.
packaging in that a rectilinear tab is cut from a strip of a second tear-resistant material which is arranged in such a way that one of its longitudinal edges coincides with the axis of the element in V-shaped, and that its ends are positioned on either side of one of the branches of the V-shaped element, and in that this tab is welded to the sheet of packaging material in au at least two points respectively arranged on either side of this branch of the V-shaped element, an end section of the tab extending beyond the edge of the precut sheet to form the free tongue of the tearing member .
the strip of the first tear-resistant material preferably has a width equal to the opening of the V-shaped element and is moved in the direction of the V axis, the strip of the second tear-resistant material tearing having a width equal to the length of the rectilinear leg and being displaced pependicularly with respect to the first and perpendicular to the axis of this rectilinear leg.
the envelope described comprises a sheet 10 precut in a tearable packaging material such as for example a heat-sealable aluminum and a tear-off member 11 partially welded to the inner heat-sealable surface of the sheet 10.
the member tear essentially consists of a free tongue 12, not welded to the sheet 10 and a tear strip welded to this sheet.
the tear strip consists of a V-shaped element 13 and a straight tab 14.
the V-shaped element 13 is cut from a strip 15 of a first tear-resistant material, which moves in the direction of arrow A or in the opposite direction.
the rectilinear tab 14 is cut from a strip 16 of a second tear-resistant material, which moves in the direction of arrow B, or in the opposite direction, perpendicular to the direction of movement of the strip 15.
This embodiment of the lifting member has several advantages. First of all the cutting of a V-shaped element 13, the opening of which corresponds to the width of the strip 15, makes it possible to perform this cutting without any fall, except that obtained at the start of the strip . cutting the tab in a strip whose width corresponds to the length of the tab, also prevents any fall during the operation.
the cutting of the V-shaped element 13 and the rectilinear tab 14 in two different bands 15, respectively 16, makes it possible to use, as required, identical or different materials for the production of the two main components of the 'lifting unit.
the two materials can differ by their color, their mechanical characteristics or their nature for reasons of cost price.
the displacement of the two bands 15 and 16 in two directions perpendicular laires makes the cutting and positioning of the element 13 and the tab 14 particularly easy.
the V-shaped element 13 is fully welded to the inner surface of the sheet 10.
the rectilinear tab 14 is welded to this sheet at at least two points, and preferably two zones 17 and 18 (hatched in FIG. 1 ) arranged on either side of one of the branches of the element 13.
This tab is positioned in such a way that one of its edges coincides with the longitudinal axis D of the V-shaped element 13 , that is to say that this edge passes exactly through the tip of this V.
the product to be packaged is a triangular portion of melted cheese whose shape is represented by the triangle 19.
the two branches of the V-shaped element 13 are arranged along the two straight sides of the triangular surface of the product 19. At their free end, these two branches end in two bent sections 20 and 21 (see fig. 2), arranged along two edges 22 and 23 of the rear face 24 of the triangular portion shown.
the free tongue 12 protrudes by a fold 25 folded over one of the sides of the triangular portion.
the opening is carried out in the following manner: the user grasps the free tongue 12, opens the fold 25 and pulls the tongue upwards relative to the upper surface 26 of the triangular portion.
This traction has the effect of initiating the tearing of the packaging at the tip 27 of the upper surface 26, this tearing then propagating along the lateral edges 29 and 30 and then along the edges 22 and 23.
the surface 26 and then the face 24 of the triangular portion are completely free, which allows the folding of the rectangular surfaces of the envelope corresponding to the sides 31 and 32 of the triangular portion. Therefore, the triangular portion is completely cleared without any residue remaining caught in the corners of the envelope.
the description and the drawings relate to the packaging of a triangular portion of a product such as for example a portion of processed cheese. It is obvious that the same principle could be applied to a product with a rectangular shape whose upper surface is rectangular or square. In this case, the opening angle of the V-shaped element is 90 ° and the branches of this element are arranged along two adjacent sides of the rectangular or square surface.
