Definitions
- the invention relates to a tubular bag with a tubular pouch body and lid, and optionally floor, especially standing or standing floor.
- Tubular bags of the type in question are well known and are used for storage, storage and transport of liquid, pasty, powdery, free-flowing and solid contents substances. They are characterized by low weight, easy formability and printability. In addition, they can be easily and environmentally friendly disposed of with appropriate choice of materials. Above all, they can be folded after emptying to a minimum volume and bring in the disposal path.
- a general problem is the opening behavior of such tubular bags or tubular bag packaging.
- the opening of such packaging is carried out by tearing the packaging, which is usually provided for this purpose an attack on a sealed seam in order to pull them apart for the purpose of opening.
- the seal should break open.
- the opening of the packaging is relatively aimless and uncontrolled, so that the packaging content is spilled, which often leads to loss of the packaged goods, especially in liquid or free-flowing ingredients.
- the interior of the tubular pouch is generally very difficult to access, since torn or stagnant packaging sections are in the way and make access to the inside of the tubular pouch, for example by means of a spoon, more difficult.
- Another opening variant provides for the use of scissors, by means of which an upper portion of the closed tubular bag is separated and removed, so that the contents of the tubular bag is accessible.
- this variant makes it possible to cleanly separate a tubular bag section which closes the tubular bag, it raises the problem that scissors always have to be at hand.
- the core of the present invention thus consists in that the tubular pouch body, which is generally cylindrical in shape, is formed by fin-seal, wherein at least one material weakening extends from the free longitudinal edge of the fin-seal over the circumference of the tubular pouch body in that, if necessary, the tubular bag along this material weakening is apparent, in particular over the entire cross section of the tubular bag body or tubular bag.
- the tubular bag is therefore not opened by removing the lid and / or the bottom, but by dividing the tubular bag body.
- the material weakening is close to the lid of the tubular bag, so that after opening of the tubular bag, the contents thereof remain securely and easily accessible in the part of the tubular bag body comprising the bottom,
- the opening of the tubular bag is made by gripping the and exerting tension on the fin-seal in the area of material weakening, so that the material weakening either is broken only over a peripheral portion or preferably over the entire circumference of the tubular pouch body.
- the weakening of the material is preferably a continuously extending embossing line which is interrupted in the manner of a perforation. Finished material weakening lines can be easily formed, in particular embossed, in the materials commonly used today, in particular laminates which are preferably used here. With respect to the materials preferably used here, reference is made to claim 8.
- a particularly preferred embodiment of the invention is characterized in that two spaced from each other in the axial distance, each extending over the circumference of the tubular pouch body material weakenings, in particular stamping lines are provided which define a tear strip between them, which begins at the free edge of the fin-seals.
- the weakening of the material preferably follows a cut formed on the free edge of the fin-seal. This incision may be formed as a pointed notch.
- the lid and / or the bottom is sealed or glued to the tubular bag body in a conventional manner.
- the tubular pouch body is made of a laminate, in particular Alur ⁇ inium-Larninat, with at least one seal and optionally at least one barrier layer.
- the barrier layer is preferably made of SiO 2 , AlO 1 , ethylvinyl alcohol or a metal foil.
- the stability and stability of the tubular bag may be advantageous for the stability and stability of the tubular bag to form the lid and / or the bottom in each case relatively stiff, preferably as a deep-drawn shell with sealable or adhesive edges.
- the floor can also be made of a laminate and formed with a V or W-fold, which also provides the required dimensional stability and stability.
- the lid and / or bottom are essentially made of the same materials as the tubular pouch body.
- Lid and / or bottom can also be provided as an injection molded part. Ultimately, this depends on the required stability, the size of the packaging and the packaging content.
- lid, bottom and tubular bag body is made to claim 11.
- cover, bottom and tubular bag body made of a material which is sterilizable.
- Tubular bag explained with reference to the accompanying drawings.
- the tubular bag is formed in the manner of a cylindrical box and provided in the accompanying drawing with the reference numeral 10. It comprises a cylindrical tubular pouch body 11 and cover 12.
- a bottom is not shown in the accompanying drawing.
- the bottom can preferably be designed in the same way as the cover 12, namely flat shell-shaped with a peripheral edge 13, which is sealable with the tubular bag body 11 at the front. The sealing takes place between the front-side inner edge of the tubular pouch body 11 and the outer surface of the peripheral edge 13 of the lid 12 or of an equally formed bottom.
- the tubular bag body 11 is made of a rectangular laminate, wherein the free longitudinal edges are connected to a so-called five-seal 14, namely sealed. Starting from the free longitudinal edge 15 of the fin-seals 14 two axially spaced material weakenings in the form of stamping lines 16, 17 are formed, which extend over the circumference of the tubular bag body 11 such that, if necessary, the tubular bag 10 along these stamping lines 16, 17th apparently. These stamping lines 16, 17 define therebetween a tear strip extending over the circumference of the tubular bag body 11.
- this strip is located near the cover 12, so that upon opening the tubular bag 11 by exerting tension on the tear strip 18 in the direction of the arrow 19 substantially only the uppermost part of the tubular pouch body 11 together with the Cover 12 is removed.
- the section of the tubular pouch body 11 that surrounds the bottom thus remains largely intact.
- the opened bag is presented to the consumer as if only the cover 12 had been removed.
- the material weakening or embossing lines 16, 17 respectively adjoin an incision formed on the free edge 15 of the fin 14, which in the illustrated embodiment is in the form of a pointed notch 20.
- the tearing of the embossed lines in the circumferential direction is predetermined and facilitated.
- the cross-section of the tubular pouch body 11 may be circular as in the illustrated embodiment. However, it is also conceivable to provide a triangular, polygonal, oval or the like. Cross-section. Of course, then cover and / or floor must be adjusted accordingly.
- the tubular pouch body preferably consists of a laminate.
- Lid and bottom can be made of the same material.
- the lid, bottom and / or tubular pouch body have a thickness in the range from 50 ⁇ to 500 ⁇ , in particular 80 ⁇ to 400 ⁇ , preferably 100 ⁇ to 350 ⁇ .
- the tubular pouch body can be torn along the stamping lines 16, 17 in a particularly controlled manner.
- a unidirectionally stretched film the molecule chains forming the film are aligned and arranged substantially parallel in the stretching direction.
- a cleavability of the stretched material parallel to the direction of stretching relative to an angled direction is preferred, so that an oblique tearing by the aligned molecular chains is made much more difficult to impossible.
- splitting or tearing of such a film parallel to the stretching direction no molecular chains are cut.
