Description

Dustproof packaging.

The present invention refers to a dust-tight container according to the generic term of the Claim 1.

These containers are in shape parallelepiped, particularly for powdered detergents, from decades ago in the market These packages are also used for spillable foods, such as breadcrumbs, cornflakes or similar.

To delimit one of these containers, particularly of those containers, formed from a call "Wrap-Around trimming" (envelope trimming), particularly used for chunk products, for example, for detergent tablets. In addition, the pills to be packed are placed stacked, for example, on an area of the base of a folding cutout and then the cutout is unfolded for closure of the container and for coating the product in pieces, wrap almost around the product, and close the container. One of these packages have to be particularly non-watertight powder.

In contrast, in the package according to gender, such and as it is known, for example, thanks to the FR-A-2 233 235, first a packaging area, which only remains open even on one side and then it is filled with the spillable product, after which the last side is closed, and therefore the entire package. Such effect, a tubular shape can first be designed from the trim and then close the base. Then the stuffing and finally the lid would close. However, in principle it is also possible, for example, to close a front face last after filling.

The present invention is based on the objective of improve a container of the class cited initially with respect to its handling.

This objective is met, in accordance with the invention, by means of the characteristic properties of the Claim 1.

The packaging according to the invention improves stability and dust tightness.

In addition, the package advantageously obtains a shape, in which the lid and base are octagonal and present, according to container body, eight surfaces. This preferably entails the fact that the front surfaces can be designed more thin through a form of ashlar. This converts for another part to the container, advantageously, in more manageable, because these containers, particularly for detergents or cleaning powders, They have a size, which can be held with one hand from the side of the shelf. This is, however, easier with the package, because the frontal lateral zone, which now consists of a face front and two adjacent additional lateral regions, follow better, by arched, the rounded shape of a gripping hand, it is thinner in the frontal lateral zone and particularly more nice, because it is less noticeably angular to grab. This It is particularly favorable for women, since they they have, on average, somewhat smaller hands than men.

For the transport of the container, for example, of an establishment to a home, such a container is put in In most cases, in a shopping bag, a bag of transport or similar. One of these bags is held and transported then usually in a somewhat oscillating manner with one hand. Also, for known reasons it can happen again and again, that the Bag hit along with the contents on the carrier's leg. He packaging is also more pleasant in this regard, because by means of refraction of the edges corresponding to the octagonal shape of the surfaces of the base and the lid the edges cease to be so Angled and collide less unpleasantly. The edges Angled rectangles can produce, in contrast, bruises. In the package the respective area is also softened corner, since no tetrahedral angled shape is designed with right angles, but in the area of the octagonal shape it develop flattened corner areas with partially angles obtuse The expression "obtuse angle", which represents geometrically an angle greater than 90º, can be taken, by consequently literally also in the connection of things described, as regards the risk of injuries.

Additionally, the container can be handled also better, even in an additional aspect. Since they exist eight perpendicular edges and surfaces, the container is much more Stable to stack, particularly also to place on pallets, not being the largest necessary occupied space, but being able to be even smaller, essentially in the corners. However, yes had to keep the same volume in regard to a reduced octagonal shape at the corners relative to a shape rectangular, one would have to provide a corresponding Higher volume height. In fact, these containers are not filled, however, to the top, particularly conditioned by the filling technique, so that it is possible to modify the state of filled inside the container without the least difficulty, without having to change the height of the container itself, that is, the measure external Also in this respect nothing has to be modified, favorably, in the container, considering storage. In Germany, the filling status must be planned within the DIN 55540

A preferred embodiment of the package provides that the additional lateral regions narrow, with respect to the width of the front faces, on chamfered surfaces. This means, therefore, that in fact they only bevel essentially the edges with respect to a form of ashlar, that is, in each case, a vertical border is replaced by two edges not very widely separated from each other. This also improves particularly the manageability and stackability of the container. The Additional lateral regions are in the tubular form preferably closed at angles of approximately 135º with respect to the front faces adjacent to them and to the face back and to the front face. They form, therefore, in their corners and edge areas with these adjacent faces an obtuse angle relatively large Regarding the sillar shape of a container usual and / or with respect to the rectangular shape of the surface of the lid and the surface of the base of a usual container, the additional side surfaces cut the perpendicular edges, therefore, diagonally an angle of approximately 45 °.

A following improvement of the invention provides that, in the additional lateral regions, the tabs against dust in the direction of the lid and / or the base connect through fold lines, which extend into the folding cut-out, in each case, between two cover tabs and / or two tabs of the base. This measure guarantees, particularly also in these areas, the dust tightness of the container according to the invention. Additionally or alternatively this could be originated or helped, if necessary, also by proper clipping of the cover tabs and / or tabs of the base remaining.

For this purpose, according to an improvement preferably provides that the tabs against dust and tabs of the lid and / or base are mutually adjacent, essentially without gaps, in the flat folding cutout.

Dust tabs can prolong particularly the additional lateral regions in its extension longitudinal in a straight line or diagonally.

As already specified, they can also consider the other tabs on the cover and the base of the octagonal shape of the lid or base. However, they can also take into account the need for space and the trimming of dust tabs of additional lateral regions, staying in part preferably these additional tabs against dust and sticking without gaps between them. A mode of Preferred execution of the package according to the invention provides for such effect, that the tabs of the lid and / or the base of the faces Extreme designs are essentially T-shaped, considering the need surface of the tabs against dust. Other additional preferred design of the package according to the invention provides, that the tabs of the lid and / or the base of the face Rear and / or front face are designed, considering the need for surface of the tabs against dust, by way of serif, wider in its boundary region with respect to the face posterior and / or frontal face, that is, in the vicinity of its lines of fold, that in a zone configured in the form of tongue more thin towards its free end.

The folding cutout is preferably glued on a junction region for the formation of the tubular form. Such effect can preferably be provided with an adhesive tab, which disposed particularly along a fold line in a free edge of an additional lateral region of the anterior face or later. The package according to the invention is then glued, by consequently, by lateral joint before filling, preferably covering an adhesive tongue and a lateral region additional for bonding, preferably in such a way, that a shock edge of the junction region is in an area of a perpendicular edge of the container. Naturally they can also provide, however, other glued, particularly also in the rear face area. However, gluing should be done preferably, so that the joint also damages the Less possible handling of the container.

Other refinement of the packaging according to the invention provides, that an easy-open band is inserted into the cutout folding, which runs essentially parallel to the lid. The container it can then be filled and sealed and opened, to then, to the conscience of a consumer, pulling the cord easy opener and, consequently, unsealing the package evidently. The lid is also particularly easy to grasp from below in the area of the easy open strip, to open it, for example, with the tips of the fingers or with the nails. For an opening simplified, the easy-open band is preferably limited by weakening lines of the material. To grab the band easy to open, a grip tongue can be arranged at one end. This grip tab is preferably designed very comfortably large, to enable a safe and easy grip. The grip tab could be designed in particular approximately the size of the thumbnail.

A further refinement of this invention provides, that a folding flap area, in which the cover remains attached to the back side, be free of the band easy open. In this way, a cover is therefore produced folding easy to open and close again, preferably regarding a lid to detach completely, in principle also possible naturally.

A refinement foresees that the internal framework protrudes above the course of the easy-opening band in the direction of the lid and remain intact of the easy band. This has two advantages. Since the internal frame stands out for over the easy band and runs a certain distance from the lid surface, the lid can be resealed so more secure, placing it during the new closure almost above the part of the internal frame that stands out. Not to harm in addition to the folding procedure, it can be provided, round the internal frame according to the rotating path of a lid folding Since the internal framework also remains free of the easy band, the internal frame also guarantees in this area an additional tightness. Particularly with the lid closed again a kind of labyrinth seal.

The internal frame may be a partial area of the folding cutout of the complete container, so that the container according to the invention, it is formed in almost two layers from a unique folding cutout in important areas. Folding cutout It may also consist of two independent parties with own folding cutouts for an outer wrap and for a internal frame In each of these two cases, it is foreseen preferably, that the internal frame is attached to the shape tubular.

Another improvement of the invention suggests, that for the new closure of the lid a joint can be provided by ratchet, which can be arranged particularly in the area of the lid separated from the flap hinge. The fold hinge could preferably be arranged on the back side of the container, while the new closure takes place, as a consequence, preferably in the area of the front face. Additional or alternatively, these closing mechanisms could be provided without However, also in the lateral zone.

The package according to the invention has preferably a transport handle for transport, preferably in the lid area. This transport handle it could also be formed by additional zones of the own folding cutout. However, it is preferably provided to couple a Band-shaped carrying handle, that is, a type of handle, with its ends in upper areas of the front faces. A mango Transportation of this type can be designed by saving material, from cost-effective and durable way, for example, from a plastic band This plastic band can, for example, rivet to the front faces tightly to dust. Of course, different possibilities of formation of a transport handle of this type.

The package is preferably manufactured in essence, of cardboard and / or cardboard. At least part of the package It can also be made of corrugated cardboard. Particularly an internal frame is preferably made of corrugated cardboard, preferably running the ridges of the cardboard waves wavy vertically in the mounted container, so that also this undulation further increases the stackability of the container. A wave of this corrugated cardboard can present, by For example, a wave height and / or a half wavelength of approximately 1 mm This entails, on the one hand, stability a very high and avoids, on the other hand, a too large expense of material, particularly from an internal framework, which starts with costs of the internal volume of the container. However, they can also clearly conceive other undulations with other dimensions of various ways

Figure 1 shows an example of execution of a package according to the invention for a powder product in a perspective view.

In the representation of Figure 1 you can distinguish a cover 1, a front face 2 and an extreme face 3 of the container The lid 1 and, correspondingly, the base does not distinguishable have an octahedral surface shape or octagonal. The body or wrapper of the container extended between the lid 1 and the base must therefore be designed as an octagon and it comprises, therefore, in addition to a front face 2, a face back not distinguishable and two extreme faces 3, in addition to even additional lateral regions 4, from which they can be distinguished two in the representation of Figure 1. These lateral regions additional 4 recognizable are located between the front face 2 and a respective extreme face 3.

Compared to a form of ashlar, the perpendicular edges of the body or container wrap they are almost cut by additional lateral regions 4, forming the additional lateral regions 4 with the front face 2 and the extreme faces 3, as well as with the back face not distinguishable, in each case, an angle of 135 °. Expressed from another so, the cited edges of a sillar shape are cut and / or broken by these additional lateral regions 4 almost diagonally at an angle of 45º. Since the additional lateral regions 4 are they design relatively thin, compared to the front face 2 and the back face and the front faces 3, the lateral regions Additional 4 appear as chamfered from the mentioned edges perpendicular to a sillar shape.

The lid 1 of the container is formed and closed by the cover tabs. A tongue can be distinguished from the cover 5 of the front face 2, a tongue of the cover 6 of the face back and two tabs of the cover 7 of the end faces 3.

In addition, in Figure 1 it can be recognized that an easy-open band 8, limited by two lines of weakening of the material 9, runs parallel to the cover 1.

Figure 2 shows the front view of the container according to Figure 1. In Figure 2 can be distinguished particularly the front face 2 and the lateral regions additional 4 adjacent to it, as well as the easy-open band 8.

If the easy-open band 8 is broken, a folding lid for opening the container, which consists of the true surface of lid 1 and upper areas 2a, 3a and 4a of the front face 2, of the additional lateral regions 4 and of the 3 extreme faces adjacent to it, extending to the line upper weakening of material 9 of the easy-to-open band 8.

Figure 3 shows the rear view of the package according to Figure 1. In Figure 3 can be distinguished, therefore, particularly the back side 10 of the container and the additional lateral regions adjacent to it. They can the extremes of the easy-opening band 8, of the that one of the ends is designed as a grip tongue 11 about the size of a finger nail. These extremes of the easy band 8 extend only within regions additional sides 4 adjacent to the rear face 10, while that the rear face 10 of the easy-opening band 8 remains totally free. Depending on the rigidity of the material of the material used for the container, a folding hinge is formed as a leaf hinge during the uncovering of the folding lid of the container in the area of the rear face 10 at the height of the band openable 8. For the formation of the container is preferably used A carton. A first uncovering of the cardboard can therefore lead to the formation of the fold hinge in the form of folds and fold lines, which simplifies a new uncover and a New lid closure. To achieve a folding flap area cleanly defined, the packaging material may weaken previously in the desired area of the back face and, eventually, parts of the additional lateral regions, or elaborate in another way, for example, by grooving.

Figures 4 and 5 show the extreme faces 3 of container 1, as well as additional lateral regions 4 adjacent to these.

Figures 6 and 7 show the top view of the lid 1 of the container according to Figure 1 and / or the base 12 of the container. In Figure 7 it can be particularly distinguished that the base 12 is formed by the tabs of the base 13 to 15 according to the tabs of the lid 5 to 7.

Figure 8 shows a perspective view of a modified embodiment of the package according to Figure 1. In this exemplary embodiment, the package has additionally received a handle 16 as a transport handle, which is articulated with its ends in the area of the end faces 3, for example, through of rivets or the like.

In all other aspects, the compliant container Figure 8 corresponds to the package according to Figure 1. The views of Figures 9 to 14 correspond to the views of the Figures 2 to 7. The same elements are designated with the same indicators than in the cited figures.

Figure 15 shows a top view of a folding cutout for the formation of a container according to the Figure 1. The same elements are also designated with the same Indicators represented in Figure 1.

On the other hand, in Figure 15 you can recognize, that for the improvement and / or guarantee of the tightness to container powder also the intermediate lateral areas 4 have dust tabs 18, which extend between the tabs of the lid 5 to 7 and in the corners make up the lid 1. These dust tabs 18 are not distinguished in Figure 1 in the finished container, because they are under the tabs of the lid 5 to 7 and are fully covered by them. They are arranged correspondingly dust tabs 18 also in the side of the base in the additional lateral regions, which extend between the tabs of the base 13 to 15.

So that the tabs on the lid 5 to 7 and the base tabs 13 to 15 limit each other, relatively without gaps, and nevertheless, the tabs can be formed and / or placed against dust 18, in the exemplary embodiment of Figure 15, the cover tabs 7 of the end faces 3 and the tabs of the base 15 of the end faces 3 are designed essentially in shape of T. This is achieved, after all, by recesses, which present these tabs of the cover 7 and tabs of the base 15 in favor of the tabs against dust 18, which prolong the additional lateral regions 4 essentially straight ahead up and down.

Apart from this, in the cut according to the Figure 15, on the right edge of the representation of Figure 15, an additional 1.9 adhesive tab can be distinguished, which for the formation of a tubular shape from the cutout can stick to the additional lateral region 4 fully to the left. Also this adhesive tongue 19 has tabs against the powder 18 at its ends. The adhesive tongue 19 is designed also, in all other aspects, essentially congruent, in additional lateral region 4.

From the cut according to Figure 15, preferably forms only the outer envelope of a container according to Figure 1. Particularly, for the reinforcement of this outer shell and / or outer shell can be used a internal frame, as exemplified in Figure 16 in a top view and according to the cutout according to Figure 15. This internal frame 20 has zones 2 ', 3', 4 'and 10', which are adapt in their dimensions to the corresponding zones 2, 3, 4, 10 of the cutout according to Figure 15. One of the 3 'end faces of the trimming of the internal frame 20 is formed by gluing two zones 3 'ends during the formation of a tubular shape.

Such a cutout for an internal frame 20 it can, in principle, also be fixed in one piece in addition to the cut according to Figure 15, so that then a tubular shape with internal frame could be formed and outer wrap essentially by double winding This full cut. However, a two-way design is preferred pieces like the one in Figures 15 and 16.

Regarding Figures 15 and 16, it should be noted in addition, that in the cut-out according to Figure 15, in the area of the back face 10 suggests a type of line of weakening or die cutting 21, which is arranged approximately at height of the easy-opening band 8 and already defines a hinge zone of blades for a flip top. The internal frame 20 does not present no easy band and also remains intact by the band easy cutter 8 according to Figure 15. The extension vertical of zones 2 ', 3'; 4 ', 10' of internal frame 20 se calculates, so that it corresponds essentially roughly to vertical extension of zones 2, 3, 4, 10 in the cutout according to Figure 15. This means that these areas of the frame internal 20 protrude above the height of the easy band 8. If the easy-opening band 8 is broken in the finished container and, of this mode, a flip top, highly flip top is created along with the flip-off areas of the lid 2a, 3a, 4a, sections are released upper inner frame 20 during lid uncovering folding and protrude particularly from the extreme faces 3 and the front face 2 of the container. The internal framework can, by consequently, enclose and maintain the product, in case of maximum filling of the container, when the folding lid is open, and, at the same time, the internal framework can serve as a guide and sealing element, in the sense of a labyrinth seal, for the flip top.

Figure 17 shows the inside face of the cutout according to Figure 15 in a diagonal view. The same elements are designated with the same indicators as in Figure 15. By reasons of clarity, in this Figure 17 they are not designated, however, All zones

From a position like this, as it is represented in Figure 17, that is, with the inner face facing up and with the outer face down, resting on a type of lower position, the folding cutout is folded, that is, by a side, for storage and stacking for provision and eventually also for feeding a machine packaging, on the other hand, although also during the formation of a container according to Figure 1, then also filling this container, during its formation, directly after a certain folding step, before closing it finally. You enter in greater detail in the folding procedures cited in relationship with Figures 21 to 28. In the folding procedures according to Figures 21 and 28, however, another Execution example of a folding cut-out, as described more in depth in relation to Figures 18 and 20. These procedures of folding must be carried out, however, in all others aspects, exactly the same as with the folding trim according to Figures 15 and 17. The folding cut-out according to Figures 15 and 17 produces a final container, which corresponds to the external drawing of Figure 1.

The folding cutout according to Figures 18 and 20 produces a container, which, in principle, looks exactly like of Figure 1, although in detail it corresponds to the representation according to Figure 28. As can be recognized in a comparison of Figures 1 and 28, the respective cover design (and, correspondingly, the design of the base) is something modified. This is caused by the somewhat modified design of the dust tabs 18 of the additional lateral regions 4 and by sorting something different, resulting from this, from the cover tabs 5 to 7 and / or base tabs 13 to 15 according to the cut-out of Figures 18 and 20, which enters Now in greater detail.

Figures 18 and 20 show a second example Execution of a cutout for the outer wrap of a container according to Figure 28. This cut corresponds, in principle, to the trimming according to Figures 15 and 17. Consequently, they are used again the same indicators for the designation of the same pieces.

Figure 19 shows the cutout for a frame internal 20, which corresponds even exactly to the compliant trimming to Figure 16, because the cuts conform to Figures 18 and 20, on the one hand, and 15 and 17, on the other hand, only differ somewhat in the design of the cover and the design of the base, so that the respective internal framework 20 remain completely without prejudice by these. Also in Figure 19 they are used, by consequently, the same indicators as in Figure 16.

The cut according to Figures 18 and 20 presents, with respect to the cutout according to Figures 15 and 17, only modified tabs against dust 18 of the regions additional sides 4, which do not continue to extend the additional lateral regions 4 essentially straight ahead up and down, but in a diagonal position.

For the placement of these tabs against the powder 18, the tabs of the lid 7 and the tabs of the base 15 resulting from this, they are also designed essentially in the form of T, although with a narrowing running diagonally, essentially trapezoidal, towards the corresponding extreme face 3, and not, as in Figure 15, by a more rounded recess. The tabs of the lid 5, 6 and the tabs of the base 13, 14 do not they are designed more essentially rectangular, as in Figure 15, but they narrow, in each case, towards their free ends and they also have in their area adjacent to the front face 2 and / or the back side 10 widenings by way of serif 22.

As previously announced, with the Figures 21 to 28 are depicted and the folding steps are described and / or series of folds with the use of the cut according to the Figures 18 and 20 and the internal frame according to Figure 19.

As previously suggested, there are two folding procedures, that is, a procedure of folding for the preparation of the folding cutout for a storage and stacking and / or for trimming feed to a packaging machine and a second folding procedure to the formation of a finished container with a filling of the container during the folding procedure between two consecutive steps of creased.

In Figures 21 to 28, for the same elements the same indicators are used as in the Figures above, although, particularly in Figures 21-28, they use, in each case, only so few indicators, for reasons of clarity, as they are absolutely accurate for the explanation of respective folding step.

Figures 21 and 22 show the folding cutout according to Figure 20, that is, with its inner face up, in two folding steps for the origin of the folded state for the storage and stacking of this folding cutout according to the Figure 22

         \ newpage
      

As shown in Figure 21, as effect, they are arranged and / or folded highly, first, on the one hand, the rear wall 10 with an additional lateral region 4 adjacent thereto and with the vertical and / or highly folded adhesive tongue 19 and, also, on the other side of the folding cutout they have and / or fold highly, on the other hand, an extreme face 3 and a lateral region additional 4 adjacent to it. The front face 2 remains with the additional lateral regions adjacent to it 4 and a face Extreme 3 additionally flat in a lower position.

The clipping areas, arranged more or less high first in Figure 21, then fold towards down and inward over the area that remains flat on the lower position, so that all the clipping gets together a flat shape on both sides, in which it can be stacked. By way of similar, the inner frame 20 according to Figure 19 bends flat on both sides and in a stackable manner, as can be recognized in Figure 23.

From Figure 24 begins the representation and explanation of the second folding procedure cited, that is, for the preparation of a finished container. Such effect, first a tubular shape is configured, as it is represented in Figure 24, from the cut according to the Figure 20, sticking adhesive tab 19 to one side of the cutout with the additional lateral region 4 on the other side of the cutout. In addition, the lid area and the base area are still open. For the formation of the tubular form according to Figure 22, the clipping is first carried temporarily from its position of storage according to Figure 22 back to the folded state approximately according to Figure 21.

In Figure 25 the base 12 zone is closed. The tabs of the base 15 of the end faces 3 are already folded in while the base tabs 13 and 14 of the front face 2 and the back face 10 are still closed, according to which the tabs on the base stick together others for the durable closure of the base 12. Also the tabs against the dust 18 on the side of the base are already folded inwards in Figure 25 and can no longer be distinguished under the base tabs 15.

In Figure 26, the base is closed and the Finished container up to that point is placed on the base, so that this cannot continue to be recognized in the representation of the Figure 26. The area of the lid 1 is still open, so that in this folding situation the filling of the container with product through the open face of the lid 1. Then the lid is also closed. To that end, in the representation of Figure 26 the dust tabs 18 are they are already folded inwards while the tabs of The lid 5 to 7 are still in their open position.

In Figure 27, the area of the lid 1 is already additionally closed, the tabs of the cover 7 folded in and unable to continue recognizing the dust tabs 18. The tabs on cover 5 and 6 are They are still in the open position. In the representation of Figure 28, the container is now filled and completely closed. Particularly, now also the tabs of the lid 5 and 6 are closed and the tabs on the lid stick together others.

For the opening of the container and for the extraction of the product now you have to grab the easy-open band 8 to the grip tab 11 and pull and tear along all your length. In this way, the flip-up lid then originates. described, which can be opened by means of the flap 21. This is shown in Figure 29. The upper part of the internal frame 20 then protrudes from the opening thus released. Is possible a new closing of the folding lid. The frame part internal 20 protruding can ensure, in case of flip top closed, the necessary friction closure, to keep the lid folding in its closed position. However, it can happen through the elasticity of the material used in the area of the hinge of foils, that the flip top always open something. To ensure a better new closure, it can therefore be planned in addition, provide for ratchet joints, particularly in the area of the front face 2 and / or in the area of the faces extreme 3, being able to refer these locations also additionally or alternatively to the corresponding zone 2 'and 3' of the internal framework 20.
