Definitions
- the present invention relates to a package having a package backside and a package front associated therewith to form a packaging space enclosed by the package.
- One side of the packaging back side and the front side of the packaging has, as a tear-open side, a tear-open region with which the packaging can be opened.
- Such packaging in particular those which are formed exclusively by direct connection of a front packaging with a package back, are very well suited for space-saving packaging flat packaged goods, such as flat electronic components, decals for scrapbooks or applied to flat substrates drugs or area-shaped drugs. But other, physical packaging goods with significant dimensions in three mutually orthogonal directions in space may be packaged in such packaging.
- a package having a package backside and a package front associated therewith to form a packaging space enclosed by the package, one side of the package back side and the package front side having a tear open portion having a smaller area than the tear side and in the plane of extension of the tear-off side adjacent to tear-side packaging material at at least two linearly independent edges and which in the unopened packaging state is separable by force from the outside at least in sections to form a packaging opening which detects the packaging space from the adjacent tear-side packaging material, the tear-open side this is formed at least in the tear region of film material.
- the tear-open area has a smaller surface area than the tear-off side itself ensures that when the package is opened there is always a portion of the packaging which is unimpaired by the opening process and on which the packaging can be held during opening.
- the tear-open area adjoins at least two sides of packaging material of the tear-open side outside the tear-open area, care must be taken that even with the packaging open, a pocket-like residual packaging space remains which, although no longer closed, is suitable for the packaged goods also at the set open packaging, so that the packaged goods when opening the packaging does not threaten to get lost.
- the tear-open side is formed of film material at least in the tear-open region, it can be ensured that the force required for opening, in particular tearing, of the packaging by at least sectionally separating the tear-open region from the remaining packaging material of the tear-open side is not excessively high.
- the film material may preferably be a film laminate constructed of at least two laminate layers.
- the film laminate may have a barrier layer, such as of metal or a metal oxide or of EVOH, SiO 2 and the like.
- a barrier layer such as of metal or a metal oxide or of EVOH, SiO 2 and the like.
- the film laminate is preferably metallized, for example by sputtering or vacuum vapor deposition.
- the film laminate may have at least one film stretched in at least one direction, so that this stretched film, preferably a uniaxially stretched film, defines by its stretching direction a crack guiding direction along which a crack preferably propagates in the stretched film and thus in the film laminate. Then, if the uniaxially stretched film in the film laminate is to impose on the rest of the film laminate the crack propagation direction predetermined by its stretching direction, it is advantageous to make the uniaxially stretched film, or a totality of uniaxially stretched films in the film laminate, thicker than each individual remaining layer of the film laminate , particularly preferably thicker form than the entirety of all other layers of the film laminate.
- the film laminate may have a polyester film, such as polyethylene terephthalate, for example, to impart some dimensional stability to the film.
- At least one uniaxially stretched film is for example a film of oriented polypropylene or oriented polyamide in question.
- the film laminate may have a layer with a color or print order and a layer of a cover lacquer.
- the film laminate can particularly preferably have on one of its outer sides a layer of sealable material, for example of sealable polyethylene or another thermoplastic material, in order to be able to simply and securely connect the front and the back of the packaging by sealing.
- sealable material for example of sealable polyethylene or another thermoplastic material
- the tear-open area is designed so that it projects beyond the packaged goods in all directions.
- the tear-open region can essentially correspond to a complete wall of the packaging space, that is to say essentially one of the packaging sides from the front of the packaging and the back of the packaging, minus any edge seams.
- the packaged goods can be completely exposed after opening the packaging.
- the tear-open area in the unopened packaging state may be surrounded on four sides by the tear-side packaging material.
- a particularly simple tearing of the packaging at the tear-open region with little effort can be achieved by the tearing-off side also being formed, at least in sections, by film material in the immediate vicinity of the tear-open region. Then, in fact, a defined tear-off distance can be introduced into the foil material by appropriate manipulation of the foil material. As a manipulation, for example, perforation, in particular laser perforation, embossing, partial slitting or even the use of unidirectionally stretched films in question.
- the tear-open side is preferably formed essentially completely from film material.
- the manufacture of the package can be further simplified and the overall weight of the package can be further reduced by forming both the front of the package and the back of the package substantially entirely of sheet material.
- the side of the packaging which does not serve as a tear-open side is formed essentially of rigid packaging material, for example of deep-drawn plastic material, compared to film material. This can be contoured in a suitable manner to accommodate the product to be packaged.
- the tear-open area is torn off from the tear-open, so that the tear-open area after making an opening as access into the packaging space during removal of the packaged goods does not interfere further.
- the tear-open region preferably at its beginning, has a grip tab.
- the grip tab when viewing the package in the plane of the tear-open side, is surrounded on all sides by packaging material on the tear-open side. In that case, in addition, if the grip tab is additionally arranged in the plane of extent of the tear-open side, the grip tab does not protrude beyond the edge of the packaging, so that it is exposed to less undesired external influences.
- the grip tab is to be regarded as being surrounded on all sides by packaging material of the tear-open side when viewing the package in the plane of the tear-off side, even though the grip tab is not completely located in the plane of the tear-open side, but in one in the tear-off side Level of the tear-up side deformed or deformed imaginary state is surrounded on all sides by packaging material of the tear-open side.
- the tangential plane at the respectively adjacent point of the tear-open side should be considered the plane of the tear-open side in the sense of the present application.
- the tear-open region runs along a predetermined tear-open path in a tear-open direction from a tear-open region beginning, preferably from the grip flap, to a tear-open region end.
- the tear-open region along the tear-open direction is shorter than the package at the attachment location of the tear-open region in the tear-open direction.
- the tear area may be striped, i. with a significantly smaller width extension compared to the longitudinal extension (in the tear-open direction) of the tear-open region, wherein the width extension is in turn smaller than the unidirectional dimension of the package at the application location of the tear-open region.
- gripping tab as such is tangible, preferably the tear with a material weakening about the tear side penetrating cut line provided, which defines the grip tab and / or through which the handle particularly easy from the Material Association of the tear is leachable.
- the gripping tab is preferably provided for ease of gripping in an area of the package in which the tear-open side is not connected to the other side of the package, to prevent material weakening such as embossing, scribing caused by the formation of the gripping tab , in particular penetration, which creates an unintentional access to the packaging space on the tear-open side, it can be provided that a material weakening, in particular penetration, produced by the formation of the grip tab is separated from the packaging space. In particular, this separation is such that the weakening of material produced by the formation of the grip tab does not violate the integrity of the wrapping of the packaging space.
- the separation of the weakening of the tear-off side generated by the formation of the grip tab from the packaging space can be realized in a particularly simple manner by the tear-open side being in each case aligned with the other side Front side of the packaging and the back of the packaging along a release region is detachably connected, which is at least partially located between the grip tab and the packaging space.
- the release region can extend over the region of the tear-open side, in which the grip tab and, in particular, the material weakening intended for its formation is provided. Then, the handle latch can be releasably connected to the other side of the packaging and only be detached from it for opening.
- the above-mentioned release region is preferably formed by a detachable, so-called “peelable” seal.
- a detachable, so-called “peelable” seal preferably the outer surface of the tear-open side pointing towards the respective other side from the front of the packaging and the back of the packaging and / or the outer surface of the respective other packaging side facing the tear-side from the front of the packaging and the back of the packaging are provided with a corresponding sealable outer layer.
- This can be provided on at least one of the said sides, preferably on both, even only pattern-like, preferably only in those places where it is actually needed for a sealed joint. As a result, a load of packaged goods by ingredients of the sealable layer with almost certain probability be avoided.
- the packaging front side and the packaging rear side are connected to each other at least in sections, preferably completely non-detachably along an edge surrounding the packaging space, and are particularly preferably connected by sealing.
- the preferred permanent connection ensures that the contents of the package can only be accessed or made accessible through the predetermined opening location, ie the tear-open area.
- the packaging can be gripped by one hand, while with the other hand, the packaging, such as after grasping the grip tab, is torn open.
- the holding section is provided in the tearing direction before a tear-open area beginning, in particular in front of the grip tab.
- the front side of the packaging from a different material than the packaging back, also from different film materials, in particular film laminates.
- FIG. 1 an embodiment of a package according to the invention is generally designated 10.
- the packaging 10 has a tear-side designed as packaging front side 12, which with an equal in the viewing direction of FIG. 1 behind packaging rear side 13 (see FIG. 2 ) is preferably connected by an insoluble seal in the sealing area 14 between the outer edge 10a of the package 10 and the Um chargedsrand indicated by dashed line 16 of the packaging space 18 formed between the packaging front side 12 and the packaging rear side 13.
- the front packaging side 12 and the rear packaging side 16 can be permanently sealed to one another while the two packaging sides 12 and 13 are not connected to one another in the region of the packaging space 18.
- dashed line 20 is a viewing direction of the FIGS. 1 and 2 shown thin packaged 22, such as a photo, decal or trained as a thin leaflet drug that is received in the packaging space 18 behind the front of the package 12, but before the packaging rear side 13.
- the packaging space 18 can, as in FIG. 1 and 2 at its upper left corner, have a bulge 18a, which can serve to form a grip tab 24, since there the grip tab forming packaging material is not connected to the back of the package and thus can be easily folded or folded out of the plane of extension of Aufr detailedseite out.
- the packaging front side 12 designed as a tear-open side can be provided with a curvilinear penetration 26, for instance in the form of a cut or a punching, so that the grip tab 24 is located around the end 26a and 26b of the penetration 26 in the plane of extension of the front side of the packaging 12 Bending axis B from the extension surface of the front packaging side 12 is bendable out to grip the grip tab 24 easier.
- the gripping tab 24 preferably forms an initial portion of a tear open area 28 which extends along the tear direction A.
- the extent of the tear region 28 transversely to the tear direction A is indicated by the dotted lines 30 and 32. These tear-leading lines 30 and 32 define a tear-open path 34.
- the tear-guiding lines 30 and 32 preferably begin at the end points 26a and 26b of the penetration 26 introduced into the packaging front side 12 to form the grip tab 24, which can serve as tear-in aid due to their notch effect.
- the rissshuntden lines 32 may by a material weakening, such as a perforation, in particular laser perforation, which preferably does not completely penetrate the packaging front side 12 to protect the packaged 22 from external influences in the thickness direction, by other material weakenings, such as material removal, embossing and the like or by a longitudinal the risswden lines 30 and 32 extending unidirectional stretching a lead in the tear-side designed as packaging front 12.
- a material weakening such as a perforation, in particular laser perforation
- the tear-open region 28 can end in the region of the packaging space 18 at its longitudinal end opposite the grip tab 24 or, moreover, can reach into the sealing region 14 or even as far as the edge 10a of the packaging 10.
- the tear-open area 28 is surrounded on four sides by the packaging front side 12 of packaging material (foil laminate) of the front side 12 of the packaging which is designed as a tear-open side.
- a sealing area 36 is preferably provided in which the inside surface of the package front 12 and the inside surface of the package back 13 are detachably connected to each other by sealing are.
- the portion 36 of a releasable seal advantageously extends transversely to the tear direction A in the plane of extension of the tear-off side (packaging front 12), preferably at least across the width of the tear-open region 28, more preferably beyond the width of the bulge 18a of the packaging space 18, such that the bulge 18a is separated from the packaging space 18 by the region 36 of the releasable seal.
- the area of a releasable seal 36 may extend in a direction orthogonal to the tear direction A also over the entire width of the package 10, if this is advantageous for manufacturing reasons.
- FIG. 2 is the packaging 10 of FIG. 1 shown in the opened packaging state.
- the tear-open region 28 was gripped on the gripping tab 24 while the package 10 was held with the other hand on the holding region 14a, and along the tear direction A by external force, in particular by tearing, separated from the surrounding packaging material of the packaging front side 12 formed as a tear-open side.
- the opening edges 38, which are preferably integrally connected to the penetration 26, have become and 40 which, together with the penetration 26, form an opening 42 of the package.
- the tear-open region 28 is shown only partially in a folded-away state away from the opening 42.
- the opened package 10 can advantageously be folded about a virtual buckling axis K passing through the opening 42 substantially along its longitudinal direction, so that the flat packaged article 22 is easily accessible from the remainder pocket 44, which remains through the remainder of the now open packaging space 18 remaining on the package 10 is formed, can be removed.
- the tear-open region 28 could easily be peeled off from the packaging rear side 13, without fear of destroying the tear-open region even before opening the packaging 10.
