Thermoformed insert for a box, especially rigid cardboard, for packing and storing a narrow film reel

The innovation concerns a deep pull insert from one molded plastic film, ir a roughly box-shaped Lower part of a box provided with a hinged lid, in particular a rigid cardboard box that is square, preferably square Basic form, for packing and storing a z.3. with prerecorded film provided with the film reel, with respect to the shape of the room in plan and height to the box interior adapted insert on the four outer edges of its end face for example the box height corresponding downwards, connected at the corners has side walls and with one from the front pulled-down (molded) circular bobbin chamber is provided which has an annular collar-like peripheral wall which at least one, but preferably two in a diagonal axis of the insert opposing molded handle recesses having.

In the known design, the bobbin insert chamber is dimensioned to be much smaller in diameter than an edge length of the insert, which is square in plan. The bottom of the bobbin chamber and the annular end face of the insert surrounding the insert chamber are smooth. The handle recesses in the annular collar-like peripheral wall extend from the end face of the insert to the bottom of the bobbin insert chamber. The VfandstMrke of the use is in all areas almost paper-thin. The insert is loosely placed in the box

The deep pulling attachment ^{y R of} the '!

Due to the grooves provided in the front of the insert, the entire edge area of the insert is stabilized and thus withstands considerable beep stresses. The durability and Eorr-resistance contributes to permanent and roughened appearance and thus comes to the wishes of customers in high ^M ass entpepen.

An expedient design of the deep-drawn insert provides that the four edge regions of the end face ^{H of the} insert are provided with bead-like edge strips formed from the end face. The edge strip supports the good appearance and particularly helps to stabilize the basic shape in the edge areas.

Another feature of the innovation is that the centering pin is formed from the bottom of the bobbin insert chamber is. In this way, an absolutely tight centering pin is created in a space-saving manner. The centering pin should If possible, one that corresponds to the Spulenoffnunp, preferably tapered fit obtained. The slope of the cone is very slight. The soul receives an exact one on such a journal Position that does not allow any sliding movements. The lifting of the coil from the pin is nevertheless easy.

The innovation also provides that the bobbin insert chamber has a diameter that is almost as large as the edge length of the square insert. In doing so, according to a training for the snule entrance chamber of the next to the four cross winds of the mission in the j \ antenna areas of the

Front side provided bead-like edge strips be tangent. A reel insert chamber that is optimally large in relation to the outer shape of the rigid cardboard box is thus created. Through the special training features provided for in accordance with the innovation but the rigidity and strength of the inlaid is guaranteed. In this case, stay in the four from the front Corners of the especially square plan are almost triangular Fields received as stabilization surfaces, the outside are limited by the edge strips above the cross winds.

The feature that the ring collar-like peripheral wall also contributes to the stabilization of the entire insert the bobbin insert chamber provided a handle recesses have a depth corresponding to approximately half the coil height. The lower part remains due to these grip recesses of lesser depth the annular collar-like peripheral wall of the chamber without any weakening notch. The current depth of the handle recess is sufficient for the reliable detection of the respective overhead coil end wall. When in a known manner diagonally or diametrically The gripping of the bobbin when it is removed is particularly important in the area of the insert corners and insertion can easily be carried out and in this case the spool can also be easily lifted off the centering pin.

To stabilize the i

Rigid cardboard box has the feature /, according to which the thermoformed insert is glued in the box base. In some cases, a bottom side of the bobbin insert chamber on the Gluing on the bottom of the box is sufficient.

A more advantageous pestilence is characterized in that the deep-drawn insert on its crosswinds to the Glued to the corresponding side winds of the box base

is. The side walls of the deep-drawn insert and the corresponding The side walls of the bottom part of the box stabilize each other. This type of attachment for use is used in connection with such hinged lids attached to the lower part, the ones on the long sides and the sweeter outer side have stiff side walls.

There is an advantageous further development of the innovation in that the deep-drawn insert in its side walls with for Adhesive uptake of certain pressed-in! in particular is provided with longitudinal beads. These longitudinal beads are pressed in from the outside, so that the open side of the groove Is facing side walls of the box base. A sufficient amount of the adhesive can be accommodated in these longitudinal sinks will. As a result, the surface areas of the side walls lying above and below the beads can be close to one another bring. This rules out the fact that there are gaps between the side walls of the insert and the bottom part of the box are undesirable for various reasons. A plurality of such longitudinal sieves can be provided one above the other.

One that takes particular account of the young appearance Embodiment of the innovation is that in a deep-drawn insert for a box-shaped box base, the three side walls connected to one another and one with the lid has connected foldable side wall, when used only the side walls adjacent to the fixed box side walls which have lip ridges intended to receive adhesive. On the fourth side wall of the insert, which is adjacent to the foldable side wall of the box base, is located no bead. This side wall is smooth. This different design of the side walls also ensures the correct one Assembly of deep-drawn insert and box base. Tn As a rule, the clearing of the bobbin chamber with writing

A particularly stable shape of the deep sieve insert is achieved if it is made from a polystyrene film. The V.'andstä'rke the polystyrene film about 0.7 ^Γ> nm should be. It is also provided that the polystyrene film has a tensile strength of around 370 kr / sqm and a tension of around 700 k? 7 sqm.

The centering pin has a corresponding to the screw opening, preferably tapered fit.

Between the centering pin and the collar-like peripheral wall 16, the bottom 18 of the bobbin insert chamber has molded and / or molded-in stiffening corrugations or bead-like impressions 20 on. Instead of these characteristics or in addition to them, several concentric to the centering pin can be used. annular grooves can be provided, which are also formed from the material of the floor.

The end face 13 of the insert is provided with stiffening recesses or formations in the edge area. These are expediently provided as bead-like edge strips 21 directly in the edge region of the end face.

The bobbin insert chamber 15 has a dimensioned almost as large as the edge length of the square insert Diameter. The dimensions are coordinated so that the Spuleneinlarekammer from the next to the four side walls of use in the p'.anten areas of the front side bead-like edge strips 21 is affected.

The handle recesses 17 are given the size shown in FIG. 1. The depth of these recesses should correspond to about half the height of the spool, so that the annular collar- like peripheral wall lf> remains unaffected in the lower half.

The deep-drawn insert is preferably glued into the lower part of the box, a particularly useful type of attachment is made of pin. 4 can be seen.

The adjacent side wall of the deep-drawn ointment remains flat and looks smooth. A large quantity of adhesive was poured into the L / In " ¹ S sic! 'En 22. v.'ir <". This amount of adhesive required for secure gluing is thus stored in the longitudinal beads. The areas of the side walls of the deep-drawn insert that adjoin the longitudinal beads. and the box base can remain pressed tightly together. No gap formation is thus caused by the adhesive layer. The longitudinal beads can consist of spaced sections in the longitudinal direction. A plurality of longitudinal beads 22 can also be arranged one above the other at a vertical distance.
