Definitions
- the invention relates to an easy-to-open, sealingly closable packaging with the features of the preamble of claim 1.
- Packaging of this type is known in different embodiments and for different packaging goods.
- the lower part is usually formed from a plastic film or a plastic composite film and has an edge flange lying in the connection plane, on which the flat or profiled cover part lies.
- This can be made of metal coated with heat sealing material, especially Aluminum foil or consist of a plastic film or a plastic / metal composite film.
- the cover part In many packages, the cover part must be peeled off as a whole from the edge flange of the lower part. This is complex and requires skill and strength. Frequently, the cover film tears, so that the cover part cannot be reliably separated from the lower part without difficulty. Problems also exist to the extent that the adhesive force meets the requirements for reliable sealing and at the same time must have sufficient easy peelability of the cover part.
- Pre-weakened cover parts have therefore also been provided, in which a tear-open area is limited by the line of weakness, to which a grip tab is assigned. In these cases, the connection adhesive force can only be selected from the point of view of a secure seal, since the packaging is opened by tearing open the cover part along the weakening line. However, there is a problem here with the assignment and arrangement of the grip tab in relation to the tear area delimited by the line of weakness.
- the invention is suitable for both single-chamber and multi-chamber packaging.
- a separate grip tab can be assigned to each chamber and formed from the lid material.
- the arrangement is particularly advantageous according to the teaching of Claim 2 trained.
- This development ensures that when the weakening line delimiting the handle section is initially broken in, tearing of the cover part is avoided. If this is done in accordance with the teaching of claim 3, the handle tab can thus be exposed without the opening or opening of the filling chamber area of the packaging thereby being opened. So you can prepare the opening process and still open the packaging for the first time at any later time.
- This measure has the further particular advantage that the floor can be designed to facilitate the opening process in a special way according to the teaching of claim 6.
- the packaging consists of a lower part 120 with edge flange 121 and one with the edge flange e.g. by sealingly connected cover part 122, which can be flat or profiled.
- the cover part 122 can consist, for example, of a metal foil, such as aluminum foil 130a (FIG. 5) provided with a sealable layer 130b, the aluminum foil being provided with a weakening line 137 which delimits a tear-open area.
- the lower part has several chambers which are separated from one another by webs 134.
- the upper side of the webs lies in the sealing plane of the edge flange, the cover part 130 being connected to the lower part in a sealing manner by sealing regions along the edge flange and along the upper sides of the webs.
- the invention is also suitable for a lower part with only one chamber to be filled with filling material.
- a tear area is delimited for each chamber by line of weakness 137, 138 at 139.
- Each tear-open area has a grip section 140, 140a, 140b formed from the material of the cover part, which extends beyond an adjacent web 134 and is delimited by a separate weakening line 141, which extends into the weakening line 138 e.g. of the tear-open part 132.
- the line of weakness is broken by finger pressure on the grip tab, whereupon the tear-open part can be separated from the relevant chamber by means of the grip tab.
- the area of intersection between the handle tab and the top of the web is designed with a lower adhesive force with respect to the sealing connection, so that the cover film peels off when it is opened from the top of the web in the area of the handle tab.
- the lower part has a web 135 completely surrounding the grip section 140, the upper side of which lies in the connection plane and is connected via a connection or sealing line 136 is sealingly and firmly connected to the cover part 130.
- the grip tab 140 is delimited by a dividing line, which can have interruptions, or by a weakening line 141, which according to FIG. 4 can be caused to break in by finger pressure.
- the weakening line 141 merges into the weakening line 138 of the adjacent tear-open area 132, delimiting a connecting section.
- grip tab 140 and associated tear-open area 132 each on opposite sides of a web, for example web 134.
- the one in itself 4 a closed web 134, 136 around the handle tab 140 has a bottom which hermetically seals this area from the filling chamber area of the packaging.
- the bottom is profiled with a shoulder 143 as shown in FIG. 4 and in such a way that when pressure is applied to the handle tab 140, the line of weakness 141 tears and the handle tab 140 is automatically erected into a position that can be detected easily.
- the weakening line 141 breaks in on one side of the web 135.
- the adjacent part of the cover 130 remains firmly connected to the lower part via the sealing line 136. A danger that the score line 137 of the adjacent tear-open part 131 will collapse is thus completely eliminated.
- the exemplary embodiments described with reference to the figures mentioned above can of course also be used optionally in a packaging which has only one filling chamber.
- the adhesive force is reduced in the narrowly limited intersection area between the grip tab or connection part and the web . This can be done, for example, in the manner shown in FIGS. 6 and 7.
- the web 117 is constricted in the area of intersection from the sealing width 117a to the web 116 with the sealing width 116a, as indicated at 115.
- the film 111 of the cover part consisting of the layers 112, 113 can be at the same temperature and pressure as in the other areas 117a with the narrower one Area 116a connected by heat sealing.
- the reduction in width results in a lower adhesive force, so that in this area when opening the cover film peels off from the lower part 110, which can also consist, for example, of a metal film, in particular aluminum film 112 coated with sealing material 113.
- the sealing adhesive force can be correspondingly reduced in the region 142 by a reduced sealing temperature and / or by a reduced sealing pressure and / or a shortened sealing time.
