Description

The invention relates to a sales blister pack for a roll with wound tape comprising a plate-shaped base with flat front and back, a fixed to the base, protruding on its front hood-like blister molding and the roll of tape in a through the base and the Form part formed blister space is held captive. Such, also referred to as blister card packaging usually has a hanging hole to hang the package on hooks or rods of a sales stand and darzubieten. The blister cards are a wrapping means for flat strip material wound on rolls such as in particular adhesive tapes, insulating tapes, sealing tapes or the like. The roll of tape is safely housed in the mostly transparent blister molding for storing, shipping, presenting and selling. Suitably, the blister molding forms the band against external influences, in particular against contact and contamination protective closed hood, which is usually made of plastic, but also of cardboard or cardboard. Depending on the type, the hood is connected to the base of the packaging by sealing, clamping, stapling or gluing. The base card is mostly made of cardboard or cardboard, printed with product and advertising information and coated with lacquer. The invention also relates to blank parts for producing a packaging according to the invention.

Usually, the blister pack for using the tape is opened by releasing and separating the blister mold from the base wall. The tape is withdrawn from the open roll or placed in a special, specially designed for this purpose dispenser. However, a roll blister packaging is also known, in which the roll bears against a base wall in a flat position and in a blister ring is housed ( DE 9012783 ). This blister hood is molded with a dispensing channel that must be cut open with scissors to use the packaging as a tape dispenser. The preparation of such a package is expensive, since a special plastic hood with mold section for the tape issue is finished. The flat position of the roll of tape on the blister card not only hinders the rotation of the roll but also limits the area for printing. To open the dispensing section, a cutting tool must be used as a tool. Use and handling of the known packaging also remain unsatisfactory, since the tape when rolling can be performed only through the output section of the blister hood and the tape to be applied must be separated with a pair of scissors.

In contrast, the invention has the object to provide a reel blister pack with integrated Abrollereinrichtung, the packaging should be easy and inexpensive to produce and use and handling of the package as a tape dispenser particularly convenient, universal and obvious.

The object of the invention is achieved in conjunction with the features of the aforementioned Blisterverpackung characterized in that the tape roll for unwinding of the tape in the blister space in relation to the base front-upright position is rotatably held, that in the base a passage is formed through which gripping the outer tape take-up end and having it unwound out of the tape into the area in front of the base-back side, and providing on the base at least one separating element for separating outwardly drawn roll tape. The invention provides a tape roll blister package which forms a complete roll-off device with all the associated elements. The front side of the packaging is associated with the packaging function, wherein the role is secured in the blister molding and expediently housed completely enclosed outside. The back of the package are essential functions of the unwinding device. In addition, the upright position of the roller in the blister molding contributes to the proper maneuverability for rotating the tape roll. Since the passage is arranged in the base wall, it can be easily designed. At least one separating element arranged at the base has the advantage that the tape can be separated from the roll or the packaging without any auxiliary means. As a result of the invention arranged Base passage, the tape enters a guide at the back of the package. This favors the attachment of the tape to an object by means of the dispenser package according to the invention. In addition, the packaging with ribbon roll or blister molding in an upright position and with protruding card sections can be particularly convenient for performing the Abroller function capture and handle. Also available on the packaging for printing with advertising / product information suitable areas.

In a particularly advantageous and preferred embodiment, the base passage is closed and openable to release the tape take-up in the open state to the outside. It is achieved in conjunction with a closed hood, that the role is protected on all sides from external influences. Suitably, the openable base passage is provided with an opening element, which is preferably formed by a separable material part. Such a separation part is advantageously a tear-open part, which can be formed expediently in particular in the form of a tear-off part or strip detectable on at least one tab, in particular on a base made of cardboard, cardboard, or the like. But it is also the formation of a Ausbrechteils z. B. on a base plate made of plastic into consideration.

The base passage expediently has a deflection / control element which deflects the roller belt out of the passage when it is pulled out. It forms a guiding and handling aid for attaching the tape to an object to be provided with it. For this function, an edge or an edge of the through opening is already quite easily suitable.

Suitably, the separating element, preferably with a simple knife-like separating edge, provided in the extension direction of the roller belt extending over the deflecting guide element behind the latter on a projecting from the blister molding base portion. In a particularly advantageous and preferred embodiment, the separating element is at the same time arranged and configured as a pressing element for controlling the adhesive side of a single-sided coated adhesive tape to an object to be provided with it. A particularly suitable arrangement according to the invention for this purpose is that the separating element in the region of a preferably made of two material layers formed base edge is formed, which is designed as a support / support edge to set up the package for applying tape to an object and lead. The dispenser blister package according to the invention is not limited to use with an adhesive tape roll. Thus, in the packaging rolls with tack-free tapes, z. As paper tapes, foil tapes or textile tapes are used. However, the packaging according to the invention is particularly preferably and advantageously provided for an adhesive film roll. The tapes may be single-sided or double-sided, optionally with the intermediate layer of a release tape, adhesive coated.

The dispenser blister pack according to the invention can be provided on the back of the pack, preferably in the region of a base section projecting from the blister molding, in a simple manner with a depositing device. This takes after tape separation, the roller belt in the region of the beginning of the tape for releasable friction and / or adhesive fixing on the packaging. Suitably, the storage device is formed by a storage surface, which adheres the adhesive tape tape and a detachable adhesive. Advantageously, the support surface is formed by a non-stick coating such that the desired adhesion / release function for the tape without destroying the same and the coating is achieved. The coating is advantageously carried out particularly heat-resistant, so that the blister molding can be connected by sealing without affecting the shelf with particular double-layered base. This is important if the seal contact heat is applied to the back of the card.

In a preferred embodiment of a band side of the withdrawn from the base passage roller belt is associated with the separating element of the blister base, while the other opposite hinge side is associated with a storage device on the base for releasable adhesive bond with the roller belt.

In a particular and preferred embodiment of the invention, the Blisterbasis from the front and the back forming sections preferably from cardboard, cardboard od. Like. Double-layered joined together. A particular embodiment is that formed in the front side portion of a tape dispensing opening of the passage and in the rear side portion delimited by lines of weakness tear-off are. Accordingly, blank parts according to the invention for producing a package according to the invention are provided such that a first blank part is formed, which forms the front side portion of the packaging base with the blister space associated cut or punched dispensing opening, and that a second blank portion is formed, the rear side portion of the packaging base with the formed by material weakening material part separable, wherein the two blank parts are provided and tailored so that covered in the packaging base double-layer assembly of the blank parts, the separable material part covers the discharge opening or releases after separation.

The two-ply base gives this particular rigidity and kink resistance. The tear-open part covers the discharge opening for closing the passage or releases it after tearing open. In this embodiment, the blister base is expedient and advantageous od by a single blank of cardboard, cardboard or the like. Formed with the formed by a first blank portion front side portion and formed by a second blank portion rear side double-layered around one of the two sections to form the Base is folded together hinged fold line, wherein the two sections are preferably fixed together by gluing.

A preferred embodiment consists in that the separating element of the blister base is preferably formed by a preferably glued fixed by cutting element in the form of a knife blade around which the blank is folded in a transition region between the front side portion and rear side portion. At least in this transition region, a tear-open part delimited by weakening lines is formed which at least partially covers the release element or releases it after it has been torn open. Advantageously, the cutting element has a separating edge which at least substantially coincides with an inwardly folding fold line over which the front side portion and the rear side portion of the base are hinged together. The blank placed around the separating element with the tear-open part in this state excludes any risk of injury at a cutting edge of the separating element. In another design, the separating edge may terminate with an outer edge of the base.

Furthermore, a particularly advantageous and preferred embodiment of the invention is that in the front side portion of the two-ply blank a tape dispensing opening of the base passage is formed and that the tearing around the partition tearing piece integrally with a below the base rear side section extending below the discharge opening, this covering Separate tear-off is. The tearing element formed thereby covers the cutting element in the open state and closes the dispensing opening, while after tearing it releases both the cutting element and the dispensing opening. Conveniently, the tear-open element is punched with a tear-open tab on both the front-side section and the back-side section, so that the tear-open element can be conveniently grasped on both sides of the package for separation.

In a preferred embodiment, the base dispensing opening and the separating part covering it for closure are arranged so that the roll of tape engages with its base-side apex in the dispensing opening. The role is then when rolling on edges of the discharge opening, so that a special guide-bearing for the coreless, therefore only circumferentially held, also largely unwound tape roll is provided.

It is expedient to use a blister molding made of plastic, which is usually a transparent hood molded from PVC, PET or the like, sealed to the base wall by contact heat. The front side portion forming the base front side is then coated with sealing wax at least in the attachment area of the blister molding. Advantageously, the rear side portion forming the base rear side is also coated with a lacquer.

the punching blank made of cardboard of the blister pack according to FIGS. 1 to 6.

From Fig. 1 to 6, the structure of a sales blister pack 1 according to the invention, the base 2 is double-layered, can be seen. The packaging 1 comprises the double-layered plate-shaped base 2 with a flat front side 21 and flat rear side 22, a transparent blister molding part 3 made of PVC fastened to the front side 21 on flange edges 32 by means of a sealed welded connection or the like and one in this blister molding part 3 Captive and rotatably held roller 4 with roller body 42 and wound thereon adhesive tape 41, which is adhesive coated on the in-winding flat side 413 in the winding. The package 1 is provided with an openable passage 5 in the base 2, which is provided in the central region of the blister space 31. The passage 5 is formed by a tape discharge port 51 punched out at the front side 21 and an opening member 61 in the back surface 22. In Figures 1, 5 and 6, the passage 5 is shown in the closed state, wherein the Opening member 61, the discharge opening 51 covers to the outside and completely closes.

The discharge opening 51 has a square shape with an edge dimension, which is only slightly larger than the width of the z. B. 20 mm wide roll 4 and the flat strip 41 is. Thus comes the role 4 with its lower apex 43 in the discharge opening 51 to lie. The dispensing opening 51 forms an enclosure, on the transverse edges 511 of which the roll 4 is rollable to sit, so that it is mounted only peripherally. Depending on the roll diameter, the dimensioning of the opening 51 is adapted in other embodiments.

The package 1 is provided on a base portion 23 projecting from the blister cap 3 on one side with a separator-cutting member 7 integrated with the double-layered base 2. The cutting element 7 is formed by a flat-shaped knife blade with a cutting edge 71 separating and stuck between the front side portion 210 and the rear side portion 220 in a flat position. In this case, an inventive blank 20 shown in FIG. 7, from which the base 2 is formed, is folded around the separating edge 71 in the region between the front side section 210 and the rear side section 220, which coincides with an inwardly folding fold line 26. Incidentally, the front side portion 210 and the rear side portion 220 are hinged to each other with an outwardly folding fold line 25. A tearing part 62 covering the cutting element 7 and lying around it is formed integrally with the tearing part 61 which extends on the base rear side 22 to below the dispensing opening 51 and covers it. This results in a strip-shaped tear and tear-off 6, which, as shown in Fig. 1, 5 and 6, in the open state, the cutting element 7 covers and the discharge opening 51 closes. When the tear-open element 6 is torn off, the cutting element 7 in the exemplary embodiment forms a web which traverses the tear-open opening. For example, it is also possible that the cutting element not at its ends, but above the tape to stick to the inner surface of the front side portion. The tearing element 6 then extends only into the edge region of the base 2.

As can be seen from FIGS. 2 to 4, the dispensing opening 51 and the cutting element 7 are released after the tearing element 6 has been torn open and torn off. The band 41 of the roller 4 has at the outer winding end, ie at the free beginning of the tape on a handle 414 formed by a paper strip. By manipulation of the opening 51, the tape roll 4 can be rotated so far that the grip 414 comes to lie in the discharge opening 51 and can be detected by hand. As shown in Fig. 2 with a first guide track 401, the tape 41 is guided to roll with its outer tack-free side 412 around the one transverse edge 511 of the discharge opening 51, wherein the tape 41 is removed at an acute angle α from the roller 4. This transverse edge 511, together with its adjoining edge side, forms an edge 521. An acute angle α also arises when the band 41 has been unwound to the reel body 42. With such angles α is achieved in cooperation with the roller 4, which engages in the blister chamber 31 centrally disposed opening 51, a particularly good rolling function.

In the course 401, the band 41 is placed on the separating edge 71. The cutting element 7 forms with the separating edge 71 at the same time a pressing and control. Thus, the band 41 can be pulled off the roller 4 in the course 401 by the blade or the separating edge 71 engaging at a flat obtuse angle β on the band 41 in the course 401. As shown in FIG. 2, the adhesive tape 41 can be guided in this way and attached in a targeted manner to an object 9 to be provided with the adhesive tape. The pressing / separating edge 71 of the cutting element 7 forms a tool of the blister pack 1, with which the band 41 can be deposited and pressed directly on the surface of the object 9 to be bonded to the tape adhesive side 413. This is done in cooperation with the remaining after separation of the tear strip 6 fold edge 251 at the fold line 25, which is placed for direct tape application to the object 9 at an angle β. This is a relatively large angular range in which the angle β remains sufficiently flat without belt separation. This allows a very simple and convenient way of handling the blister unwinder according to the invention with only one hand. In order to cut through the band by means of the separating edge 71, the knife of the cutting element 7 is brought at a steep angle γ to the strip surface. This is shown in FIG.

Another possibility, however, is to pull the adhesive tape 41 over the deflecting / guiding element 52, which is formed by the edge 521, without bearing on the packaging rear side 22 out of the dispensing opening 51 and to attach it to an object. In any case, the tape is cut to cut a portion around the cutting edge 71 of the cutting element 7 at a steeper angle than in the application.

In the region of a base portion 24 which protrudes on the other hood side, a storage device 8 is formed on the packaging rear side 22. This is formed by a storage surface 81, which has been applied in the form of an anti-adhesive layer on the package back 22. On the shelf 81, the strip beginning 416 of the roller 41 is stored after the separation of a piece of tape. This is shown in Fig. 4. In this case, the belt 41 is discharged with tangent 402 tangentially from the roller 4. The adhesive side 413 of the band 41 adheres to the layer and can be detached from it residue-free, sticky. Thus, the dispenser package 1 is available for further unwinding of tape 41 with a defined, clean and ready held adhesive tape beginning available.

Further details of the construction and the design of the packaging 1 according to the invention with double-layered blister card in the exemplary embodiment will be explained with reference to FIG. 7. The blank 20 made of cardboard or cardboard shown there is divided in half into the two rectangular congruent sections 210, 220. In Fig. 7, the blank 20 is to be seen with the surface that comes to rest on the package 1 outside. Accordingly, the outwardly folding fold line 25 can be seen, over which the front side portion 210 and the rear side portion 220 are hinged to each other. Along the imaginary center line 201 of the blank 20, starting from the one transverse or narrow side of the blank 20, a hanger hole 11, the depositing surface 81, the tear strip 6, the discharge opening 51 and a hanger hole 12 are formed. The shelf 81, the tear strip 6 and the dispensing opening 51 are aligned along the center line 201. The tear strip 6 extends for the most part in the rear side portion 220 and with a substantially smaller part a piece beyond the fold line 25 in the front side portion 210. Im Area of the shelf 81 facing the end of the tear strip 6, the tear-open portion 61 extends for the Opening 51. The other end portion of the tear strip 6 forms in the region of the fold line 25 in the sections 210, 220, the tear-open part 62.

In the embodiment, the tear strip 6 is formed by a perforation 63 with Gegenritzung. This is produced by staggered perforation or scribe lines 631, 632. The scribe lines 631 lie on the top and outside of the blank 20 seen in FIG. 7, while the scribe lines 632 are attached to the other surface side of the blank 20. The scribe lines 631 and 632 delimit the rectangular tear strip 6 lengthwise.

At the narrow ends of the tear strip 6 narrow sections 64 are punched out, protrude into the tabs 65, which can be lifted out of the blanking surface and form handles for tearing and tearing of the strip 6. Of course, the tear strip 6 is dimensioned so that it completely releases the opening 51 which it covers in the packaging 1 after it has been torn off.

The tear strip 6 has at least on the back 22 of the package 1 on a bandwidth corresponding width. The opening formed in the region of the fold line 25, 26 is sufficiently large after the strip 6 has been torn open and torn off in order to place the strip with its band width around the edge 71 of the cutting element 7. Incidentally, in the rear side portion 22, the flat space formed by severing the tear strip 6 forms a flat channel adapted to the bandwidth 60, in which the band extending to the cutting element 7 is particularly guided.

The surface of the blank 20 shown on the outside of the package 1, shown in FIG. 7, provides a relatively large area which is printed with advertising and / or product information. To make the package 1, this outer surface is painted. The front side portion 210 is coated with a sealing lacquer, while the other blank half, namely the rear side portion 220 is coated with a heat-resistant lacquer which is solid during sealing operations. Before the two blank sections 210, 220 are folded onto one another, the bottom surface of the blank 20 is provided with a gluing, which is expediently applied in the form of adhesive strips or cords in the region of the edges of the blank 20. After folding around the fold line 25, the two sections 210, 220 then joined together by gluing firmly and undetachably. The sections 210, 220 come to lie flat against one another with the pressure-free and lacquer-free inner / lower surface of the blank 20, with the blade element 7 being made sufficiently flat. In FIGS. 1 to 4, for purposes of illustration only, a gap which does not actually arise can be seen between the folded-together sections 210, 220. The hanger holes 11, 12 are congruent to each other. The sealing of the base 2 with the blister cap 3, which is filled with the roller 4, takes place by contact heat applied from the rear side 22. The blister cap 3 is given a shape that is adapted to the roll shape in diameter and width.
