Definitions

  • the invention relates to an adhesive piece comprising a carrier strip divided into a central strip and two edge strips with an application of a pressure-sensitive adhesive on its underside and with protective films placed on the adhesive application on the edge strips.
  • Adhesive tapes have been known in many embodiments for decades. Adhesive tapes are commercially available in lengths of a few decimeters or a few meters. There are also pieces of adhesive with a length of the order of 10 or 15 cm. The adhesive pieces are sold in these short lengths, or the user cuts an adhesive tape to the length desired by him for the adhesive piece. Adhesive tapes and pieces are used, among other things, to prepare and seal boxes so that they can be sent as a package by post. In recent times, efforts have been made not only to use fabrics once and then throw them away, but to use them twice and, if possible, more than twice. This results from the idea of avoiding rubbish and protecting the environment. People will become more economical again.
  • Cardboard boxes are suitable for repeated use, in particular if they consist of a stable cardboard and this was not or hardly damaged when it was first used as a cardboard box and when it was first shipped as a package. Adhesive tapes are required to produce a new box from an old box. Adhesive tapes are therefore becoming increasingly important.
  • tabs start from the outer edges of the outer strips. These can easily be grasped with two fingers. This makes it easier to remove the protective film.
  • one part of the box is swiveled by 90 °, so that one part of the box then forms the front and the other part of the box, for example the right side of a box.
  • the abutting end faces of the two cardboard parts with the adhesive piece run along a quarter circle after the pivoting of the one cardboard part by 90 °.
  • the center of this quarter circle lies on the inside on the inside wall of the two cardboard parts or on their inside edge.
  • This quarter circle has a length of «2 ⁇ r. r is the thickness of the cardboard parts.
  • an inventive design which allows the adhesive piece not to stretch to the limit of its tensile strength even after said pivoting of the one cardboard part by 90 °, it maintains its tight fit and does not deform the end faces of the cardboard parts become.
  • This embodiment is characterized in that the median strip has at least one corrugation. The curl can be pulled apart and thus leads to the desired stretch.
  • the protective films prevent the adhesive piece from sticking immediately when it is first placed on a piece of cardboard, even if it is not yet in its intended position.
  • the protective films give the user time to push the adhesive piece back and forth until it is in the desired position. So that it remains in this desired position, the user must press the adhesive piece with the finger of one hand. This is annoying.
  • the invention provides an expedient embodiment which makes this pressing unnecessary. It is characterized in that at least one protective film has a cutout that passes through its inner and outer strips. This means that the adhesive application is exposed here. Through the cutout it can be on the cardboard part or the like Chen be pressed. This gives the adhesive piece an initial hold that is sufficiently firm for the first handling.
  • a large number of pieces of adhesive are strung together to form a practically endless adhesive tape. It is therefore within the scope of the invention to provide an endless adhesive tape or a few centimeters, for example about 7 cm or about 15 cm, long adhesive piece with the above-mentioned features.
  • 1 is a plan view of an embodiment of the adhesive piece
  • FIGS. 1 and 2 show the perspective illustration of an application of the embodiment of the adhesive piece shown in FIGS. 1 and 2,
  • FIGS. 3 and 4 shows the perspective illustration of a further application of this embodiment.
  • 7 shows a partial top view of an application of the embodiment of the adhesive piece shown in FIGS. 3 and 4 and
  • Fig. 8 is a partial perspective view of the application shown in Fig. 7.
  • FIG. 1 shows the adhesive piece 12 with its left edge strip 14, the central strip 16 and the right edge strip 18.
  • the undersides of the two edge strips 14 and 18 are coated with an adhesive application 20.
  • 2 also shows the two protective films 22 adhering to and covering the adhesive application 20.
  • Each protective film consists of an inner strip 24 and an outer strip 26. These are connected to one another along the fold lines 28.
  • the inner strips 24 adhere to the adhesive application 20 and cover it.
  • the protective films are folded by 180 ° along the fold lines 28.
  • the outer strips 26 run outwards and end in the tabs 30.
  • the tabs are 30 square or rectangular pieces with rounded corners. The representation as arrows is intended to symbolize that the tabs 30 are pulled outwards in the direction of the arrows when in use.
  • FIG. 4 contains only this reference number 32.
  • the remaining parts have the reference numerals drawn in FIG. 2.
  • Figures 1 and 3 also show the cutout 34. It is a cutout in the inner strip 24 and outer strip 26 of a protective film 22. These cutouts lie one above the other, form the cutout 34 and thus allow free access to the application of adhesive at this point 20.
  • the median strip 16 can also contain two corrugations. Just- if necessary, the inner and outer strips 24, 26 of the right protective film 22 can also be left out to form a further cutout 34.
  • Fig. 5 shows the part of a carton 36 with a cover part 38. This is to be glued to the other cover part.
  • the adhesive piece 12 shown in FIGS. 1 and 2 is glued onto the cover part 38.
  • the adhesive application 20 located there comes into contact with the cover part 38 and fixes the adhesive piece 12.
  • the user pulls on the left in FIGS. 1 and 2 Drawn tab 30. With that, he pulls off the protective film 22.
  • the result is the image shown in FIG. 5.
  • FIG. 6 shows a carton 36 with two cover parts 38 and a visible narrow side 40. This and the invisible bottom are glued and connected to one another by adhesive pieces 12. Each time an adhesive piece 12 is pressed on with one half and fixed to the cutout 34, and the protective film 22 is pulled off. The other half of the adhesive piece 12 is then pressed on, and the second protective film 22 is pulled off at its tab 30.
  • FIGS. 7 and 8 show an application of the embodiment having the corrugation 32 and shown in FIGS. 3 and 4.
  • Two cardboard parts 42, which in the final state enclose an angle of 90 °, are to be glued to one another. For this purpose, they are placed in one plane as shown in FIG. 7.
  • An adhesive piece 12 having a corrugation 32 is placed and glued onto it.
  • FIGS. 7 and 8 shown position in which they enclose an angle of 90 °. They swivel around the inner edges of their abutting end faces. Their outer edges move away from each other. The resulting elongation of the adhesive piece 12 is absorbed by the corrugation 32. This means that the edge strips 14 and 16 adhering to the two cardboard parts 42 can maintain their position.
  • This application shown in FIGS. 7 and 8 occurs, inter alia, when the Karrton 36 shown in FIG. 6 is produced from a blank or from a cardboard box that has already been used and then turned over.

Abstract

Une bande adhésive comprend une bande centrale et deux bandes marginales sur la face inférieure desquelles est appliqué un adhésif qui est recouvert par deux feuilles de protection repliées sur 180° aux bords intérieurs des bandes marginales, de manière à former une bande intérieure et une bande extérieure. Des languettes sont assujetties aux bandes extérieures et permettent de tirer aisément les feuilles de protection même lorsque la bande adhésive est déjà posée sur les pièces à réunir. Dans un deuxième mode de réalisation, la bande centrale est ondulée. Les ondulations absorbent des étirements causés par le pivotement des deux pièces que l'on veut coller.
