description the embodiments

The embodiments are exemplified on a thermoformed thermoformed pack described. Floor parts by cold forming or by injection molding are made, are also used as a base.

• – Ein erstes Aufnahmevolumen für das anzuwendende Produkt,
• – ein zweites Aufnahmevolumen für einen Energiespeicher, und
• – ein drittes Aufnahmevolumen für eine Startersubstanz zur Aktivierung des Energiespeichers.

All embodiments have in common that three receiving volumes are provided in the package:

• A first volume for the product to be used,
• - A second storage volume for an energy storage, and
• - A third recording volume for a starter substance to activate the energy storage.

Picture 1 shows a packaging 1.0 in full section and in plan view. In picture 2 is the packaging 1.0 without the product to be used. Figure 3 shows the activation of the packaging. Picture 4 shows the packaging after opening.

The packaging consists of a common packaging element 1.0 with a middle part of a thermoformed thermoforming film 1.1 , which is sealable on both sides. It is a circumferential, cup-like depression 1.1.1 pronounced, which receives an energy storage SE1 in the form of a heat releasable activatable chemical substance such as sodium acetate trihydrate, which emits a certain amount of heat, for example, in an exothermic reaction, which is initiated by activation of a starter substance. The starter substance is a leaf spring 1.9 , which releases the pulse energy to initiate the exothermic reaction in the energy storage with slight compressive stress. The bowl 1.1.1 for the energy storage SE1 is designed so that it shows a reversal of its shape in the central area and so another cup-like depression 1.1.2 for receiving a product SA1 forms.

Both cups are so from the common thermoforming film 1.1 educated. The bowl 1.1.2 for the product SA1 protrudes into the bowl only in the area h1 1.1.1 into it, leaving the bowl 1.1.1 is embedded in the energy storage SE1 in its predominant area.

The bowl 1.1.1 stands with another one cup-like depression 1.1.1 for receiving the leaf spring 1.9 in connection. The connection between the cup 1.1.1 for the energy storage SE1 and the cup 1.1.3 for the leaf spring 1.9 is designed so that both cups form a unit, the leaf spring 1.9 but by a constriction it is fixed so far that its location on the cup 1.1.3 remains limited.

The bowl 1.1.1 for the energy storage SE1 is with a cover foil 1.2 , which is preferably applied by sealing, tightly closed.

The bowl 1.1.2 for the product SA1 is with a cover foil 1.3 , preferably by sealing in the area 1.3.1 peelbar closed. The cover sheet 1.3 is designed so that it is at appropriate subareas over the interface 1.3.1 of ground foil 1.1 and cover sheet 1.3 in the form of a peel-bag 1.3.2 protrudes.

To activate the packaging is on the thermoforming film 1.1 and the cover sheet 1.2 in the area of the cup 1.1.3 Pressure on the leaf spring 1.9 exerted (Figure 3), which releases a stimulation energy. This triggers a continuous reaction in the energy storage SE1, whereby heat is released. This transfers over the thermoforming foil 1.1 on the product SA1. After sufficient warming of the product SA1 can over the Peelasche 1.3.2 the cover sheet 1.3 from the bowl 1.1.2 removed (Fig. 4) and the product SA1 is used.

Figure 5 shows a second embodiment, a package 3.0 , It is essentially identical to the packaging 1.0 , Only the striking differences are described:

The bottom shape BF of the cup 6.1.1 corresponds essentially to the negative of the outer shape AF of the cup 6.1.3 , The bowls are covered with a cover 6.2 peelable, preferably closed by sealing flat. The bowls 6.1.1 and 6.1.2 are additionally surrounded by a circumferential seal SF, which in this area a non-detachable connection between the bottom foil 6.1 and cover sheet 6.2 manufactures. Between bowl 6.1.1 with his extension cup 6.1.2 and the bowl 6.1.3 for the application substance are perpendicular to the outer edge of the package, two perforations or embossing lines as bending edges BL1 and BL2. The bowls 6.1.1 and 6.1.3 are arranged so that their imaginary center axes M1 and M2 are at the same distance from an imaginary symmetry line SY between the two bending lines BL1 and BL2. If only one perforation line is congruent with the symmetry line SY. The bowls 6.1.1 and 6.1.3 are also on an imaginary common line LG perpendicular to the symmetry line SY. For later detachment of the cover film 6.2 over the bowl 6.1.3 for the product SA5 is an area 6.5 seal-free and in the direction of the free end of the package by a cutting line SL in the cover sheet 6.2 or divided by a perforation. At a suitable point is in the direction of the outer edge of the packaging 6.0 a cut or a form punching 6.6 attached, which allows the fixing of the kinked packaging.

Figure 18 shows the cut of the receiving element. Figure 1 shows the receiving element before gluing or sealing. Figure 20 shows the elements of the pack in perspective. Figure 21 shows the sixth embodiment when folding the receiving element. Figure 22 shows the packaging 8.0 after folding and fixing the receiving element.

The packaging 8.0 includes a receiving element 8.1 , For example, a blank of cardboard or composite materials, for receiving and fixing the position of the first packaging element 8.2 for receiving the energy store SE6 and the second packaging element 8.3 for receiving the product SA6.

The first packaging element 8.2 to accommodate the energy storage SE6 consists of a one-sided sealable, thermoplastic deformed bottom foil 8.2.1 , This is a cup 8.2.1.1 for receiving the energy store SE6, which is extended by a cup 8.2.1.2 for receiving a leaf spring 8.9 pronounced, according to the first embodiment. The bottom shape BF2 of the cup of the first packaging element 8.2 substantially corresponds to the negative of the outer shape AF2 of the cup of the second packaging element 8.3 for the product SA6.

The second packaging element 8.3 consists of a thermoplastic deformed bottom foil 8.3.1 and a cover sheet preferably applied by sealing 8.3.2 , A seal-free area that acts as a peel lash 8.3.3 can be used, facilitates the removal of the cover sheet 8.3.2 to use the product SA6. The second packaging element 8.3 can also be constructed as a commercial Abbrechpackung.

The cut 8.1 for receiving the two packaging elements 8.2 and 8.3 is constructed in the form of a book cover with internal pockets T1 and T2. In the simplest case, a rectangular blank Z serves as the basic element whose end regions E1 and E2 are folded inwardly about folding edges F1 and F2 so that after sealing or gluing in the regions B1, B2, B3, B4 the pockets T1 and T2 arise. Here, the inwardly-placed sections E1 and E2 of the blank Z leave uncovered a region B5, so that it can be used in the region B6 as a card back which is delimited by the folding edges FK1 and FK2 running at right angles to the outer edge.

The inside part of the pocket T1 is in the area 8.1.1 in the form of the two connected bowls 8.2.1.1 and 8.2.1.2 recessed so that the first packaging element 8.2 can be inserted into the pocket T1 with inwardly facing cups. The inside part of the pocket T2 is in the area 8.1.2 in the form of the cup of the second packaging element 8.3 spared.

For easier removal of the second packaging element 8.3 is the recess 8.1.2 designed to the final contour EK1 in the area B7 open. Another withdrawal of the outer contour in the area 8.1.3 facilitates the insertion and removal of the second packaging element 8.3 ,

This situation can eg by a glue flap 8.4 be fixed.

To use the packaging, the adhesive flap is first 8.4 solved and activated the packaging in the manner already described. Re-fixing over the adhesive flap provides intimate contact of the wells of the two packaging elements of the thermoformed packages 8.2 and 8.3 so that the resulting heat is transferred to the product SE6. After heat transfer, the thermoformed pack 8.3 The product can now be removed after opening the thermoformed pack 8.3 be used.

The Packaging according to The application examples shown are in the majority of cases Use intended as a one-time use of the product. As the energy storage reset to its storage state by supplying energy can be, is the packaging depending on the design of the packaging element Also suitable for repeated use. The described embodiments use a leaf spring as a starter substance, other commercially available starter substances or starter elements such as e.g. Spiral springs are also usable.
