Description

The subject of the invention is a container and a tray it has to manufacture this container.

Packaging containers having two are known welds crossing each other, of which at least less one forms a butt joint in which the packaging material is connected by the surface with the inner sides facing each other. Ko¬ Preferably, containers of this type are made of tape we material with a thermoplastic coating, at how the longitudinal edges of the tape are held together by the bond longitudinal to form a pipe which will be filled afterwards the packaged material is subjected to pressure tapping on each other flat and welding along narrow zones perpendicular to the pipe axis and is divided into individual containers. Containers may be subject to further transmission operations shape and are separated from the pipe by means of cutters in the welding zones.

Tape of packaging material for manufacture of this type of packaging containers it consists of a backing layer covered with at least less on the one side it is meant to create inside of the packaging container, coating with a thermoplastic material such as polythene.

The tape is usually stored in the form of rolls, and the shape of the tube is given to it during the process manufacturing the packaging by corresponding it curl up and connect the longitudinal edges with the pine tree with longitudinal joints.

Packages o the so-called cushion shape, if the jaws Welding flats and seals the pipe in the same way my welding plane; you can also disable face single quad-shaped packages bricks, which are obtained when barking welding seals compress the pipe in such a way that two the following welds are performed one by one for the other at an angle. You can also turn off after welding or in combination with them, operations shaping the shape in such a way that the bottom part of the pipe will be given the shape of a parallelepiped with a quart roma walls parallel to each other and two cover walls placed opposite each other, formed by the crushing of the poles ry with the simultaneous formation of biceps triangular ears at the corners of a parallelogram packaging.

The packages of the type described above are opened by cutting or cutting off small parts ka, as a result of which the contents of the package become available; can also be predicted in the net weak places near the packaging, for example weld corners or ribs that allow relatively easy to tear if the material is wrapped has weakening perforation.

Use of a knife, scissors or other tools other aids to open the fire Forging is not convenient because these items its kind are not always available. Easy to tear Other weaknesses in packaging also have the disadvantage of the walls 85 1403 packages are weakened perforation intended to burst, etc. as a result of which they may occur accidental tears during transport or manipulation of packaging containers.

It is also known to be used for opening bursting thread wrapped in a fuel or in the packing seam by means of which The package can be opened by cutting.

Such tearing threads are used in the known art packages, but only in those cases in whose packages are made of separate ones pieces of fabric, the threads breaking they are inserted separately into each piece of paper the packaging material before it is disposed of not the shape of the packaging. Difficulties in introducing tear thread for packaging containers manufactured from a tape coiled in a tube rely on the fact that the tear thread is cut in it the time when pipe sections separated by sections are separated cross welds from the remainder of the pipe, it means that the burst thread is not available from outside of the package when the package is to be left Open.

The object of the invention is to avoid these disadvantages carriers. The object of the invention is to develop a packaging container made of a tape rolled into a tube in which the thread or tape is torn Wajaca is available from the outside, and elaboration tapes for the manufacture of this container, supplies nej, in the bursting elements.

This task was achieved according to the invention of this way the container made of tape was overlaid thermoplastic material in which longitudinal edges of the tape are connected longitudinal a weld to form a pipe which is filled the material that is intended to be the contents of the packaging n, the pipe being shaped by successive flattening and welding along narrow zones perpendicular to the pipe axis, it is divided into individual packages which can be to be subjected to subsequent transmitting operations shape and separating from the pipe by cutting into the zone the profession of welding.

Tape of packaging material for manufacture The container according to the invention consists of the value of a pliable backing having at least one side coated with a layer of thermo material plastic. The essence of the invention lies in the fact that tearing threads are attached to the layer thermoplastic tape according to repeated pattern whose position on the ribbon is determined so that the bursting threads in the finished package are located directly below the welds.

The subject of the invention is illustrated in, for example, the embodiment in the drawing in which fig. 1 shows a diagram of the device to be converted tapes of packaging material in packaging o oval-shaped, fig. 2 - device for converting the web of packaging material in packages with the shape of a parallelepiped, half shown schematically, Fig. 3 - other devices to convert the tape into the packaging material bathtub in packages with a parallel shape of the wall, Fig. 4 - tape of packaging material from applied burst thread fig. 5 - tape ma- 85 140 4 packaging material with a continuous thread attached tearing Fig. 6 - tape having a different design wife bursting thread, fig. 7 - tape about more another arrangement of the breaking thread, fig. 8 - tape tear-thread packing material in the form of a loop, Fig. 9a - a large thread breaking when enlarged, Fig. 9b - a multi-thread tear in a large magnification, Fig. 9c - tear strip large magnification, fig. 10 - packaging ! 0 not parallelepiped with breaking thread, fig. 11 - four-sided packaging with a tearing thread, fig 12 - tear-thread packet in the form of those of the ring loops, fig. 13 - first phase the operation of opening the package shown in Fig. 10 and Fig. 14 the further phase of the operation opens of the four-sided packaging shown in Fig. 10.

In Figures 1, 2 and 3, three different devices are shown manufacturing of packaging from a tape transformed into pipes with which they can be according to the exclusion The present invention preferably produces packaging containers tubs with tearing thread.

1 is a schematic representation of the device for the production of four-sided packaging, including feed roller 1 from which it unwinds there is a flat material tape 2. The tape passes by a control roller 4, by means of which the tape is bent in such a way that it makes a movement downwards.

'Then a tape is broadcast, using u- the shaping row 6 is in the form of a pipe 9, the bottom of which is loose edges are connected by a weld seam oblong.

Thermoplastic coating during welding the tape is heated to accelerate joining and the layers of the heated material are terraced face to face squeezed together so that Chinese melting of myiaitephrials teirimoiplasityciz- 40 years. This longitudinal connection is made with the device 8; then shape it When the pipe 9 is filled, it is filled with the material intended for packaging through the filling tube niajaca 10, the outlet of which is inside 45 dives 9. With help not shown in the picture The welding jaws are then pinched and welded along narrow perpendiculars to the axis • pipes of the welding zones that are relative to each other arranged at an angle, thanks to which it obtains 50 series of 12 packages in the shape of a tetrahedron.

Then the packs of 12 sts are separated tetrahedron for tube and packed in 13 boxes for distribution.

In the machine schematically shown in Fig. 2 55 for packing, parallel sided packages 3 are produced as previously described, with what the web of packaging material 2 is from wrapped from feed roller 1, it then proceeds by the control roller 4, whereupon the strip 2 is a hundred rolled in tube 9 using the device 6 shaping. As previously described are connected, using the device to weld jacego 9, overlapping edges of tape 2 for pieces longitudinal weld of the pipe. The material that 65 is going to fill the packaging is delivered - \ 5 connected to the inside of the cart through the inlet pipe jaca 10. Then, with the help of not shown in drawing of the welding equipment, the pipe is split in sections with distant weld zones 11, while the lower parts of the tube have been joined by welding are separated for give them the shape of parallelograms 3, which are separated from the pipe 9. Their triple bisectors the ears are then folded in towards side or bottom walls of the packaging, so that an object with the shape of a parallel is obtained nu without any clearly protruding parts.

With the packaging machine shown in Figure 3, similar parallelepipeds are produced packaging 3 and, as was the case with the previous of the packing machines described above, tape 2 tape the packaging material is unwound from the cylinder feeder 1. However, in a packing machine according to fig. 3 the web is folded twice behind with guide surfaces 7. Double the folded ribbon is passed over a roll or over the air guide 4, larger diameter, changes direction of movement. The tube gets flattened cross section, it is welded along its edge using the longitudinal device welding, and the material to be filled packing nothing is delivered directly before joining the edges by heat-sealing through the filling tube 10.

To facilitate subsequent packaging production van, the web of packaging material has an exclusion crumple pattern 14 for easy crease.

The shape is given as in a baking machine of the forging according to Fig. 2, by flattening the lower parts of the pipe 9 in such a way that at the corners of packaging, triangular biceps have formed ears. After separating the finished package 3 from of the pipe 9, the triangular ears are curved in a harnessed manner as described and attached to the side walls and bottom packaging. When making a pipe with the packaging machine shown in fig. 3 the longitudinal edges of the tape 2 are joined together He does not weld himself to the overlay, but a joint is formed by touching the two internal surfaces which causes the pipe to be welded longitudinally it will look like an external rib on the packaging container 3 made with with this machine. As can be seen from fig. 3, the manufactured parallelepiped object possesses width greater than height and opposite to what takes place in the packing machine According to Fig. 2, individual packages are excluded from the run from the machine according to Fig. 3 with their longitudinal axis on transverse to the longitudinal axis of the tape.

Transverse welds of the pipe 9 in the packaging according to Fig. 3 are longitudinal joints and packaging containers, while the longitudinal seam of the pipe 9 is positioned at the halfway point top wall of the container is packed wego 3 and passes through two-sided triangles ears placed on the upper surface of the container packaging cords. This means that the ribs are served in, which are located on the upper surface of of the packaging produced according to Fig. 3 is the case longitudinal seam of the packaging material tape, 85 140 6 while the corresponding ribs on the welds on the upper of the wall surface of the packaging made of 2 is the transverse joint of the pipe z , the packaging material.

Packaging containers according to the invention can can be manufactured with packaging machines shown in Figs. 1-3 by assuming that a thread the tearing material will be attached to the tape of the mat the packaging material from the following and about it. It is assumed that the material is ribbon the packaging is fed with a sterilizer important feed mechanism, as a result of which printed text on the ribbon of the packaging material the pattern of the streaks used for ease when making the folds, and the threads also break ce are placed in the places intended on finished package and tearing threads they are placed directly under the joint that is going to cut open with this thread.

Figures 4 to 8 show sections of the webbing tape the packaging material used in the above description used packaging machines for manufacturing packaging containers. Tapes of material packaging marked with 2 have the patterns of the strips 14 for ease of shaping here a tube made of tape 2. As already before said tape should move to the front in a rhythm according to this pattern, in order to wande fesztailtiu and reading the threads tearing that could be performed in the correct half lying down.

Tape stretch of packaging material that corresponds to one package, fits the room between two consecutive lines 20 (dot - dash - dot) that define this section of tape 2, which will be located on the between the transverse joints of the pipe. The tube was formed on the Z tape will be after flattening and execution of welds cut along line 20. A pattern of 14 streaks *> run is also shown with dot - dash lines ^ ka - dot, and this part of the pattern from which it intends get to make the binocular triangular ears of the container intended for places to be emptied nanny is marked with 24. As shown in Fig. 4, the web of the wrapping material is bathtub 2 has tearing threads 21 which are folded double zone and attached at a pro-angle straight to the longitudinal axis of the tape directly below weld and separation zone marked with line 20 on 50 tapes. The tearing thread 21 runs through its own two main parallel parts 23 in half forward tapes up to point 24 or beyond, then when part 22 of the breaking thread 21 forms the loop is placed outside the left bank 55 g of the tape. That part of the breaking thread 21, which she is embodied on the inner side of the shore of the tape is attached to this side of the tape, with which you intend to create inside the container packaging and which is the coated layer 60 of a thermoplastic material such as polythene.

Preferably, the tear thread 21 has also a coating made of thermoplastic material, which is heated to soften before fixing the 'breaking thread' for this purpose, «That the breaking thread adheres with great force ad-7 hesion to the tape of packaging material when it is pressed against it.

Another variation of the z tape is shown in Fig. 5 the bursting cap is attached, the sash no packaging material is similar to of the tape shown in Fig. 4. However, the thread breaks there is a continuous thread 21 in FIG. 5, which in some in cases, it is facilitated by its automatic re-attaching knitting. In this way, a fastening is possible the bursting thread 21 according to fig. 5 using devices to carry out ni / tiki which develops nit ke 21 and puts it on tape 2, heats the thread and seals it to the inside of tape 2. This the device is placed on the side and comes closer each time it comes to the marked zone line .20 to form loop 22 outside ext the outer edge of the tape and then it is guided in the transverse direction of the belt to point 24, tooth two parallel threads were placed directly moderately under the joint.

The disadvantage of the method according to Fig. 5 is a loss the number of thread as the tear thread 21 has been folded along the strip 2 in its longitudinal direction, along the between successive tear zones it cannot be used. A further disadvantage is tear thread impossible to remove 21 after tearing the package open. The other side advantage is to prevent thread breakage without tearing the packaging at the same time.

Another type of tape of packaging material is shown in Fig. 6; tear thread 21 is continuous thread and is secured with folds together with their parallel sections 23 directly under weld and separating zone marked with line 20, however, care must be taken that the folds pass through beyond point 24 for the package to be opened these by tearing it exactly at the top of the triangle long ears. If the tear thread is at confirmed according to what is shown in Fig. 6, there is not such a large thread loss because this part of the bursting thread 21, located at the outside of the tape edge of the packaging material 2, it can be used as a grip when opening wound to the packaging container.

Packing material tapes, such as polyethylene shown in Figs. 4, 5 and 6 are intended for use in the packaging machines according to FIG. 2, this means or in machines with transverse welds the tube formed are placed at the top of the container packaging; is thus provided. that part of this weld has been opened by tearing not when opening the package, but as far as shank of the triangular ear.

The same type of thread fastening tears A connector as shown in Figs. 4, 5 and 6 can be used you on the tapes of packaging material that are to be converted into packaging in machines for packing according to FIG. 1, that is to say on the package quadrilateral. However, in this case, it is not no packaging material the pattern of prazków 14; however, it is understandable with the bursting threads 21, which are attached to tapes must be placed directly underneath this zone in which one intends to create a zone transverse welds of the pipe. (5 140 8 Figures 7 and 8 show a different type of material web packaging 2, which is intended to be used for use in packaging machines of the description type with reference to Fig. 3. As above-mentioned nanny, containers are made on these machines packaging with a longitudinal axis directed along the transversely to the longitudinal direction of the tube; upper village the end of the packaging container with a rib the welds should be opened by tearing at and opening the package will be placed on the tape have 2 along its longitudinal edge, incl left edge fall.

The bursting thread 21 with one part 23 is located directly below the zone separated by and welding of a pipe made of tape 2, under time when the other part of the 25th breaking thread 21 is placed on the outside of the edge of the tape in the joint shown in Fig. 7. Tape 2 is folded underneath in a packing machine along the middle line and both sides of tape 2 are joined by a weld seam oblong with internal surfaces facing each other, while part 23 of thread 21 • will be placed directly inside the longitudinal weld of the pipe, under the time when part 25 of thread 21 will be placed on outside the longitudinal weld of the pipe. However, these Czech those of the bursting thread that are placed inside between parts 23 and 25, will be placed lengthwise the pipe joint.

When the webbing of the packaging material remains converted into four-sided packaging, lot 25 The bursting thread will form freely separated end of thread accessible from the outside of the package, on the and part of the 23 thread will be placed exactly not inside the joint that will be cut avoiding the upper end surface of the packaging through one upper triangular top ear ear ear. When you grab part of the 25th thread by hand and pulls it upwards, the joining joint above part of the 23 thread is torn and formed 40 hole, through which the packaging can be emptied the content in it.

Another variant is shown in Fig. 8 tape of packaging material in which the thread tearing 21 is in the form of circles that can be 45 connected on one edge of the tape with the packaging material vat; part 23 of this ring thread roz¬ rival 21 is placed inside the edge tape and is attached to the inner pocket top strips of packaging material, 50 times when the other part of the breaking thread 21 is placed on the outside edge of the webbing packaging 2.

The bursting filter is thus positioned that its front part will be placed in the 55 near the zone marked with line 20, along which the pipe formed from the tape will be transversely welded and cut off. A formation was formed when the package was opened from the tape of the packaging material 2 pulls for the ring thread 21, which becomes 60 pulled top edge of the container joint of the packaging up to the top of the ear triangular it creates an emptying hole packaging with the contents in it.

A thread can be used as a breaking thread 65 of textile or of a plastic such as re has a relatively small extension, for example z polyester. Due to the absorption of the thread fluids textile are less suitable for threads bursting and more desirable thread of two plastic.

Polyester and other materials of similar character strength and elongation properties basically they have the fusibility point altogether higher than the melting point at e.g. polytene clade, which is the most used the material the cover the tape the material the packaging it is difficult to connect via hot welding with a bursting thread of polyester polirtene coated string.

To enable the joining of the breaking thread shown in Fig. 9a by hot welding with plastic coating packaging material cover the thread beforehand tearing 30 coating 31 easier to melt poly- this all or from a material called hotmelt which is a mixture of thermoplastic materials distinguished by lurking very big grip in the top in good condition. Such material may, for example, make up I give it with a mixture of polyolefillin and waxes that they are mixed in such a state that gives mate rial with the desired melting point. Coating no 30 threads may be made by dipping her in a bath made of polyolefin or hotmelite pcidgrzamego to the melting point, adJbo too otherwise by dipping in a polyethylene solution discharged in toluene all or other suitable a solvent which evaporates during drying the thread is submerged, leaving a thin coating materials.

(It has been found that the gang is important to ensure high adhesion between the tearing thread and packaging material, because in otherwise it would be easy to pull the nifka out of packaging malterial without opening the packaging nia. High adhesion strength is achieved when when the contact area of the welding between the thread and the ribbon of tanning material is suitable no big. Split has been found to be advantageous lazing niltki on a large number of thin threads, from which each has a (plastic) coating for example polytene or hotmelt.

Fig. 9b shows this loosely intertwined multi-strand breaking line 32 flattened by squeeze. When pressing the line to the fabric tape or the packaging, after having previously warmed it up, to activate the shell material, it remains so flattened that a wide upper contact between the line and the webbing and the strap this is a strong adhesion. Because each individual Connect the bursting line 32 along Fig. 9 is coated with a readily melting material polyolefin or hotimelt, each existing the waxy canal is welded when squeezing the bursting tape, thanks to which The breaking line has no saturation properties. IN continue to ensure that the thread is tearing It won't absorb liquids, it's preferable cutting off the bursting line with a hot knife, which he fuses the ends of the individual threads together and that the way the ends of the breaking lines are sealed 15140 nione. The multi-thread 32 line also has the advantage of that, unlike single threads, no cuts into fingers when the line is pulled by hand tearing open to open the package.

Another variation of the bursting element is the front shown in Fig. 9c. This element is a strip 33; preferably coated with a readily melting coating 34 for easy-to-make and durable connections. The tear strip has the advantage that it is uniform and without waxy tubules, which should be sealed to prevent absorption no liquids. The tear strip also has a function Let it have a large contact surface thanks to which it can be fastened with great force to the tape of the packaging material with the help of hot welding. On the other hand, a belt burst 33 sometimes gives poorer burst results it is harder to tear the package.

It has been found that in some cases It is preferable to use a breaking thread p like this small diameter so that it is smaller than the thickness bala plastic shell in the area welding area to be opened through burst. It was found that the bursting thread was like this the selected diameter will be cut by the plastic material in welding area so that the inside of the often a coating will remain in the torn joint plastic on both sides of the joint.

If the tear thread is too thick in relation to towards the thickness of the plastic coating w weld zone, some parts of the fibrous material which always attach to the plastic shell plastic where the paper is packaging material, are pushed to the side sides, which means that the opening spot looks like less preferably with broken paper fibers and hanging edges of the plastic.

What has been said above cannot be a problem, however used for all types of fusible materials 40 Kowam and all kinds of threads to tear jacych. It has been found, however, they can for example by means of a multilayer bursting 21 years tear off the connection point without breaking it, probably due to the tearing thread 45 due to its flattening ability, it was accepted have aama in the right way in the burst zone a shape that prevents unnecessary shots foam packing material.

It was previously mentioned that the multi-yl rope was the rival has some advantages, however that there is a risk of liquid being absorbed by the line, if the hairline of the line is not on your own sealed in a certain way. Besides the above mentioned single-thread coating, or the entire line with plastic, you can also splicing threads% low-temperature plastic the melting temperature, for example, of polytene, together with with higher temperature plastic threads melting curve, for example polyester. 60 Plastic with low melting temperature will melt in the breaking thread and flow out around the passage of the breaking thread through the connection ^ water-free and will create a weld seam of the pipe. On ffi the effect of sealing one side of the tubules in »u huddled in this area and seals on the other side pipes that may have remained in the weld caused by the transition at this point of the breaking cable, wear is thus ensured fully tight passage of the breaking line. This is basic condition for the use of packaging baths according to the invention for sterilized materials important.

The flat tear strip shown in Fig. 9c does not it must necessarily be made of a homogeneous texture plastic; it can also be spotted or cut a hangover from more threads. Some of these threads it may be low-temperature plastic fusible nature, or these threads may be coated treated with the described method, coating of the material synthetic material with a relatively low melting temperature good.

In cases where due to construction or the stiffness of the packaging material, it is difficult to completely eliminate the channels leading to leaks in the longitudinal joint around the line in which the line passes through this joint, the can apply locally around one edge today the tape, at the point where the bursting thread passes, plastic sealing coat o low melting point or from hotmelt.

In Fig. 10, a parallelglass container is shown packaging unit produced on a baking machine of the forging according to FIG. 2, for the execution of which Tasime of Vedic packaging material was used lug fig. 4. As can be seen from fig. 10, the surface of the 43 moun- tains the cover of the packaging container has a joint 40 that extends across the surfaces covers 43 and triangular lugs 42 which are located on opposite sides of the cover surface 43. Weld or weld rib 40 is double the transverse welds of the pipe 9 from which the container is wrapped the new one has been made; in place 44 transverse The joint 40 guarantees that the vision joint 41. Yes as before, the burst thread is marked by 21 and that part of the tearing thread 21 which is attached to a tape of packaging material g 2 shown in Fig. 4 is indicated by 23.

As shown in Fig. 10, the tear thread 21 is shown its parallel sections 23 are placed directly under the weld rib 40 and available from the outside, the loop 22 of the tearing thread of the container the packaging material protrudes through the longitudinal seam 41 directly below the transverse seam 40. For the run, so that during the shaping of the pipe, parallelepiped eagle, freely protruding loop 22 of the breaking thread 21 did not break between the welding jaws during the execution transverse weld 40, it is desirable to bend as shown in Fig. 10, loops 22 at the edge of the tape towards that side of the packaging material, which is to form the outer surface of the package loops 22 to the edge of the mat of the packaging material easily breakable seam in such a position that the loops are prevented introducing it into the welding zone. In here In the example shown, loop 22 of the burst thread 21 is oblique in the opposite direction to weld 40, which can be easily done on a tape the packaging material according to Fig. 4, if 85140 12 the loop will be bent with the help of a pro ¬ tect rails or guide rollers; you should be careful to loop 22 for forward motion Forward tapes reheat automatically in in the opposite direction to the conveyor belt.

As can be seen in Fig. 10, the parallel sections 23 ns bursting line 21 are arranged so that they pass beyond the corner of 24 triangular ears 42, which is evident also combined in Fig. 4, where the corresponding point 24 io is marked with an arrow. The tearing thread may be very flattened if it is shaped like a the clade shown in Fig. 9b. It was found that both time channels that form leaks do not occur in the longitudinal seam, despite the fact that the thread tears Wajaca goes through it.

In Fig. 11 a fourth pack is shown wall with thread bursting 21. As before quadrilateral packing shown in Fig. 11 may be substantially made of tape 4, but it is not required that the ribbon has 14 fold line pattern; packaging takes on au¬ automatic tetrahedron shape, if transverse the welds 40 of the pipe are positioned with respect to each other at an angle. Four-sided packaging has also the longitudinal weld of the pipe 41; as in the case of in the case shown in Fig. 10, longitudinal welds and the transverse tubes 41 and 40 cross at point 44.

The loop of the breaking thread 21 passes through the joint ine longitudinal 41 directly under point 44, then i.e. directly below the transverse weld 40, and in parallel, offsets 23 of the bursting thread 21 are welds located below the transverse zebra 40 and goes all the way to point 24, where this point corresponds to point 24 in Fig. 4. In this case, towards the loop 22 of the tearing thread 21 is extended from the cross-weld zone 40. The loop 22 can naturally bend as shown in Fig. 10 on the edge of the tape and attach it to the outside the surface of the package, however it is not 40 shown in Fig. 11.

Tear thread 21 packages according to fig. 10 and 11 can also be arranged as shown in Figs. 5 and 6, but the principle is the same as in Figs in the packages in Figs. 10 and 11, 45 from the packaging tape shown in Figure 4.

In Fig. 12, a parallel- made on a packaging machine Figure 3, from a strip of packaging material according to fig. 8. From fig. 12 it can be seen that the package is 50 parallelogram 'and with on the top cover 32 a bad seal or a weld seam is visible on 41 through the lid and through adjacent to it triangular biceps ears 42, - up to their tops. On this package, v 55 in contrast to the packaging shown in 10, a rib or weld 41, which is shown in FIG it goes through the cover 43 is the longitudinal weld of the pipe, from which the packaging container was made, while the welds that divide these pipes towards with transverse, they are located on opposite walls on the packaging container and are marked by 40. Because in the packing container according to Fig. 12, all longitudinal and short joints river pipes result from interconnecting 65 net sides of the material, the welds converge in 85140 13 common point and therefore does not arise the so-called intersection of the joints (corresponding to the point angle 44 in Fig. 10.) In the packaging container according to Fig. 12 a ring thread is attached to the tape rival as shown in fig. 8, part 23 the bursting thread that is attached to the tape, is located below the welded zebra 41, which is the longitudinal seam of the pipe from which it is fired the forging is done. Breaking thread 21 it is so positioned at the edge of the cloth tape or packaging that goes straight to the middle of the of the transverse weld 40 of the pipe and thus to the shank of triangular ears 42. When the thread breaks the tray will be torn out, the weld 41 will crack along parts 23 and the packing container can be created after lifting the triangular ears 42 i widening the gap formed in the weld 41, creating a hole through which you can empty the container with its contents dear.

You can use it in the production of packaging also made of tape of woolen packing material long fig. 7. Then we get instead of loops to pull the torn thread formed by part of the thread wajaca 21, free hanging thread part rival which, as previously described, belongs to in this case, lead from the area of the weld longitudinal, that is, it must be folded over the edge tape today.

Figures 13 and 14 show how the container is opened a packaging member made according to Fig. 10; after tap dancing when opening other types of poetry packaging containers is similar, and from this therefore no detailed description is needed this When the packaging container is to be opened made according to fig. 10 to get to his content, you should first of all raise your ears 42 up, so that they practically lie on the half top cover 43 of the packing container.

Then the loop 22 attached should be released to the lid 43 of the packaging container with a the power of an easily broken joint. Then connect carry up peitle 22, bursting 21, as shown in Fig. 13, an arrow and then a thread the bursting 21 will intersect the weld 40 near point 45 sections of 23 threads> rozryiwiajaiciej <placed under sipoiina 40. If in the next sequence it will be pulling the tear-off cable, the weld 40 will stop Newly open to the whole length up to the corner 24 triple ear 42, then throw it away fired embarrassing 21.

An opening is formed in the packaging container can be widened by lightly pressing on the sides of the container near the triangular base ear 42, with the triangular and adjacent ear parts of the torn weld 40 and the lid 43 of the container Together, the packaging material forms the environment the diamond-shaped opening 46, which is shown in Fig. 14v To facilitate the formation of this rhombus it is advisable to have an ideal emptying hole the lid 43 of the packaging had a positive embossed on it knot lines 47 which come off one side it is easy to create the opening for emptying, and the other 14 on the other side they stiffen this emptying opening as well as the surroundings 46 of the opening to be formed the diamond hole did not collapse and did not narrow which could cause the contents to splatter side of the container.

The solutions presented here are aimed at only an example of the subject invention and therefore within an idea of the invention can be changed and about the construction of packaging, as well as their appearance and composition material i. patterns of use of thread tearing jacej. 1S
