Description

The invention relates to a blank for manufacture a packaging with a rigid outer shell and flexible inner lining. GB-PS 7 19 608 is a cut of a Pack with inner lining known in which the opposite side walls have to be supplemented by a plate-shaped rigid base part so that a usable pack is created. This, after completion, three-dimensional pack can be used for Store it and do not fold it flat for shipping once it has been assembled Consumers of the packaging and efficient storage of the not yet filled packaging take place, these must be delivered cut to size and at the place of use d. H. be assembled on the filling machine. However, this is increasing undesirable because the assembly of the pack blank at the filling location for the user such packaging material results in a considerable additional expense.

In contrast, it is the object of the invention to provide a package blank of the type described at the outset create, which enables the production of a pack, which also in the finished state until filling Can be folded flat and can be transported and stored at least as space-savingly as the Blanks themselves while they are unfolded, filled and filled without additional effort can be locked.

According to the invention, this object is achieved in that several rigid warid parts lying flat next to one another are provided, which are connected to one another via fold lines and can be folded over to form a tubular envelope around these fold lines then running in the direction of the longitudinal axis of the envelope and with subsequent mutual gluing of the free longitudinal edges of the wall parts are that a wall portion having at its upper edge an on this edge protruding and extending over the entire width of the lay-flat envelope formed by the Umklappvorgang tear strip with a prepared tear line, that a tubular bottom-sealed lining in the flat zusammenge- laid-over state and at one of the Wall parts is fastened so that their longitudinal fold lines extending in the longitudinal direction of the hose extend parallel to the fold lines of the wall parts and their closed ones

Bottom opposite opening extends with its edge up to the level of the tear strip and that on the Inner surfaces of the tear-off strip and the other wall parts KJebstoffaufgabe are applied over which of the tear strip adjacent edge portion 5 of the lining and the lining itself after Forming the outer shell can also be connected to these shell parts.

The pack blank designed in this way enables the production of a finished pack with a rigid outer shell and flexible inner liner which, after completion, can be folded completely flat until it is filled is, can be straightened up solely by loading the side edges in opposite directions and then after after closing it is held in the erect state by the filling. In addition, this Cutting of the opening area of the inner lining in contact with a tear-off strip used for opening be closed in a controlled manner while opening the inner liner can be done in this way by removing the tear strip. Of the Tear strip preferably has a portion protruding beyond the edge of the liner opening with a hanging opening. The portion of the extension protruding from the edge of the liner opening can also be designed as a handle for the packaging.

The packaging blank is normally designed without a rigid casing bottom, so that the Lining is exposed on the bottom side between the shell side walls. If necessary, but can also to the lower ends of the wall parts end closure flaps, one of which is an end closure flap compared to the one wall part has a smaller width and can be folded over a fold line with this wall part is connected, with two further end flaps connecting to the end flap on both sides, each of which with one wall part as well as with the other wall parts via a fold line is connected, and from these fold lines at the two ends of each further end closure flap two additional fold lines in the wall parts on both sides of the fold lines in between converge towards each other and end at a distance from each other. This training the End closure flaps lead to an additional bottom part that comes with the packaging after completion of the packaging the Seitenwändtn is collapsible, so that the advantage of the small footprint of the unfilled Packaging is retained during shipping and storage.

An expedient development results from the fact that the tear-off strip sits on an extension which is connected to the Warid part by a fold line. This way the packaging can be used after the first time can be conveniently closed again. Advantageously, the wall part is also included Tear-off strip opposite wall part of the folded outer shell with a cut free Provide a tab for inserting the folded extension after removing the tear-off strip. the The lining of the package blank can be in the area of its closed lower end opposite the Wall parts of the outer shell, it is also recommended that the sealed bottom of the lining t> 5 neighboring sub-arteries of the folded Outer shell opposite wall parts to shape curved downwards so that the pack can also be set up securely on a base after it has been unfolded

In Fig. 1 there is shown a cardboard blank that has been cut and scored and opposing side walls 1 and 2 which lie next to one another and are united along a notched fold line 3. One Fastening flap 4 is notched with the opposite side of the main wall 2 along a side Articulation line 5 articulated. The side walls 1 and 2 expediently have the same length and width, see above that when they are fastened to one another in a tubular shape by means of the fastening flap 4, a sleeve with form two walls.

The main wall 1 has a fixed molded extension 6 which protrudes upward from it and is limited by a dividing line 7, with the help of which it can be torn off from the main wall 1.

The pack is provided with a tubular liner 8, which in the embodiment shown with a longitudinal rib closure 9 and a bottom closure 10 is formed. For the Lining can use different materials

be det, like ζ. B. non-fibrous layers, films or composite webs where one Barrier layer made of plastic material is drawn or stacked on paper or foil. Such Lining materials are normally heat sealable so that both the longitudinal and the bottom hems can easily be made by the application of heat and pressure. Essentially the fold-flat liner has opposing major walls with a width approximately equal to the width corresponds to the main cardboard walls 1 and 2. In the illustrated embodiment, the length is the Lining in such a way that its bottom seal 10 coincides with the lowermost edges of the main walls 1 and 2, but at its upper end the opening of the lining protrudes over the upper edge ti of the main wall 2 to cover the extension 6 when the cardboard structure is formed into a tube.

The cardboard blank and liner can be easily assembled into a collapsed, fold-flat package construction using such devices as are widely available in the industry. Thus, the cardboard blanks can be seen in the direction of arrow A in FIG. I while the liner is being applied to the advancing blank in the manner shown in FIG. Dots of glue 12 and 13 have been previously applied to the inner surface of the main wall 2 so that the lining adheres thereto. Similar dots of glue 14 and 15 are applied to the inside of the main wall 1 and a horizontal adhesive strip 16 is applied to the inside surface of the tear strip 6. When the cardboard blank with the lining placed on the main wall 2 continues its movement in the direction of the arrow A , the fastening flap 4 is folded inwards in order to cover the adjacent edge of the lining. Glue is then applied to the exposed surface of the fastening flap, whereupon the main panel 1 is folded inwardly along its fold line 3, thereby forming the main panel 1 and

to put on and fasten before the lining, whereby the side edge of the main wall 1 is attached by adhesive to the fastening flap 4, so that on this Way the in F i g. 3 is formed of the collapsed, flat-folded package construction shown in FIG. In In this state, the packs are sent to the packer for erection. Filling and sealing sent. When folded flat, the packs can easily be placed in loading containers for transport and packaged for storage that will take up a minimum of space.

In the hands of the packer, the flat-folded packs can be easily erected by applying an inward pressure against the opposite side edges of the cardboard sleeve formed by the folding lines 3 and 5, as indicated by the arrows B. This pressure is used to widen the opening of the lining, since it is attached to the main walls 1 and 2 as well as to the tear-off strip 6 with adhesive. Alternatively, the opposing walls of the package can be expanded by holding their opposing side edges in a substantially fixed position and contacting the end edge of the extension 6 with a tab or similar device 17 which translates the extension transversely to thereby open the opening To open the lining, the uppermost canoe of the lining 8 preferably ends shortly before the uppermost edge of the extension 6 to form an end edge on the extension 6 that can be touched with the tab 17 or another bending device , which is used to expand the main walls I and 2 relative to each other and to open the Ausklcidungsöffiuing to the filler.

ίο When the liner opening is open, the The contents of the pack can be filled using conventional filling devices of the type before depends on the content with which the pack is to be filled. Commercially available at most standing fillers will fill the packs with expanded liner openings and while they are are usually held in a slide or other package holding device, indivi a funnel moves past, which dei in the oil Pack enters and a predetermined amount de; Content there. Such a filling funnel may be rotatably or pivotably arranged to enter the opening of each package it expediently moves over a short distance with the pack while it is vorwärtsbe is moved away.

After the contents have been picked up, the package is conveyed to an ITi sealing mechanism which Liner opening closes and seals. How it ir

5, the opening of the liner are expediently closed by heat by placing them between heated pressure rollers 18 and Ii that work together to form the opposite side edges of the lining opening tion to each other and seal them with heat zi to thereby the in this way formed end closure 20 to effectively attach to the extension 6 Pappver.

As can be seen in Figure 6, there causes; Contracting and closing the opposite lowering sides of the lining opening that the

the content tending to flex the opposing major walls outward and thereby the To push the lower edges of the main walls 1 and 2 apart, creating a lower part, au that the pack can stand. Since the main walls are bent towards the outside, their lower edges tend to be arch relative to a flat support surface upwards zi, so that the bottom edges of the main walls 1 unc 2 Avoid line contact with the support surface In order to compensate for this irregularity, the lower edges 21 and 22 of the main walls in the manner shown in FIG. I. and 2 be bent outwards, this curve shape would serve to deflect the walls to compensate and thus a substantially linienför shaped contact between the lower edges of the walls and the counter, the shelf or the like, on which the packs stand with their ends.

It should also be noted that it is important that the glue dots 13 and 15 above the lower edge of the liner at a considerable distance to be ordered. When the package is full and the main walls of both the liner and the body are in place If this surrounding sleeve is expanded outward, the bottom seal of the liner tends to sag to automatically fold upwards to compensate for the expansion taking place. This state is shown in FIG. f

and Fig. 8, where it can be seen that the bottom closure of the liner folds up when the opposite walls of the pack are expanded. As a result, it is useful if the Adhesive dots 13 and 15 are arranged at a distance upwards that is sufficient to make them natural To allow expansion of the otherwise flat lining.

In the hands of the end user, the pack can be easily opened to reveal its contents emptied by simply tearing off the tear strip 6 along its dividing line 7. This Tear-off process, which is shown in FIG. 7 is shown, is used to automatically open the liner that the The opening edge of the lining on the tear strip 6 in the area of the end closure 20 is effective is attached, while the main walls of the liner are attached to the main walls 1 and 2 of the cardboard sleeve in will. Such a strip of extra soft material is used when it is over the top edge! 1 of the main wall 2 is folded to keep the flap part 27 in the closed folded position, the ends of the

Liner 8 are clamped therebetween.

F i g. Figures 12-14 show yet another embodiment of the invention in which the package is provided with a flat, substantially rectangular bottom. In this case, the main wall sections are la

to and 26 on opposite sides of the main wall 1, on which the inner lining when lying flat Outer shell blank is glued on in advance, hinged along fold lines 33 and 34, üie main wall sections 2a and 26 can overlap each other and one Form longitudinal closure 35 when the structure is assembled into a tube. An end closure flap 36 is along the lower end of the main wall 1 hinged to a fold line 37 and with a snap tab

9 shows a modification of the invention in which the tear-off strip 6 is widened to form a protruding tab 23 with an opening 24 therein, by means of which the pack can be conveniently hung on a hook or a pen for exhibition purposes can. Optionally and as shown in FIG. 10, the tear-off strip 6 can be expanded by one Carrying handle 25 with a finger grip opening 26 therein by means of which the package is conveniently carried can be. Such a construction is particularly suitable for relatively large packages.

Fig. 11 shows a further modification of the invention in which the extension of the upper end of the Main wall 1 is made in two parts, the extension having an inner flap part 27 which is hinged to the main wall 1 along a fold line 28, while an outer extension part 29 with the inner part is connected by a dividing line 30. In

Liner 8 is adhesively attached to the outer extension member 29 so that the liner is opened when the outer extension part is torn off along its parting line 30. The inner The flap part will remain behind, however, and thereby form a reclosing flap with which the upper The end of the liner can be folded over the upper edge 11 of the main wall 1 if the inner The flap part 27 is folded over along the fold line 28 which coincides with the edge 11 If desired, a deflectable tongue can be used

31 to accommodate the flap edge in the main wall 2 can be provided to the free edge of the Cap 27 to receive when it is folded over. Optionally, the hinge line 28 can have a strip

32 made of extra soft material, such as. B. thin aluminum sheet, be covered, which both at the Main wall 1 and attached to the flap part 27 on opposite sides of the hinge line 28 35 provided. It will also be noted that diC End closure cap 36 is centrally spaced relative to main wall 1 where end closure flaps 39 and 40 are provided which lie on opposite sides of the end closure flap 36. The flaps 39 and 40 are divided by fold lines 33a and 34a, the formed in the extension of the fold lines 33 and 34 and the flaps in inner parts 39a and 40a, which are hinged to the main wall 1, and in outer parts 396 and 406, which are hinged to the lower edges of the main wall sections 2a and 26, respectively are. It will also be noted that pairs of inclined fold or score lines 41, 42 and 43, 44 of the opposite ends of the flaps 39 and 40 to fold lines 33 and 34, respectively, upwards and inwards run through the main walls.

J5 It should be understandable that when the blank initially formed into a tube to form the collapsed package structure which inner and outer flap parts 39a, 396 and 40a, 406 extend relative to one another along fold lines 33a and 33a, respectively. 34a fold. In the hands of the packer, however, the end flaps can easily be erected to form a square bottom for the pack. For this purpose, the flap sections 39a, 396 and 40a, 406 are common along their Joint lines on the main walls folded inwards, these lines being an extension of the fold line 37 get lost. At the same time, the adjacent portions of the main wall 1 and the composite main wall 2a, 26 fold along the inclined score lines 41, 42 and 43, 44, thereby simultaneously removing the portions of the main walls that lie between score lines 41, 43 and 42, 44 lie, bend, whereupon the end flap 36 can be folded in, while the flap 38 between the side edges of the Flap parts 396 and 406 and the composite main wall 2a and 26 is inserted so that the Construction is brought into the erected state shown in FIGS. 13 and 14. Then it can Filling and sealing the liner in the above described manner.
