Description

Technical field

The invention relates to a packaging element for protecting a Object in a rigid or semi-rigid container polygonal cross section against impacts.

By rethinking in the field of packaging ecological considerations must be common for hitherto Packaging designs a new solution can be found. Of the Transport of relatively compact, heavy objects with complicated outer geometry, such as B. with connection flanges and actuators equipped fittings, requires special precautions to protect the items against mechanical damage caused by impact are caused. In particular, the one straight or oblique fall dangerous.

The item must also prevent slipping in the package be protected, as otherwise not predetermined locations can be taken into account when interpreting the Packaging was not taken into account.

State of the art

So far, objects of the type mentioned above have become stiff or semi-rigid containers, which are then packed e.g. B. were filled with foam flakes. In addition, one Packaging method applied, in which the item in  a negative form, e.g. B. made of foam, is inserted before it is packed in the container.

There are concerns about the continued use of such techniques regarding environmental sustainability and the desire for one Recycling versus. With a waiver of so far The materials used must therefore be searched for new solutions become.

It is also common to see the item in the container to determine in its position that spacers, for. B. multilayer cardboard blocks, between the object and the wall of the container. The elasticity of this However, spacers are usually very small and an impact can only be mitigated to a small extent. Deform the spacers even under load, so is hers Recovery is usually poor. Another Shock is the object of increased acceleration forces exposed. Therefore, these spacers are for those at risk of impact Objects cannot be used. They are also for different Sizes of an object a variety of corresponding Keep spacers ready.

Another type of packaging is that the Space between the object and the wall of the Stuffed with crumpled paper. Here a certain elasticity is created, the effort is but high. In addition, the crumpled paper with special technical features that relate to the Impact costs. For example, the paper must be damp be repellent so as not to become soft after prolonged storage become and lose tension. The adaptation to different sizes of the object takes place at the Stuff the gaps. That has a high Material consumption resulting in small objects, which  packed in containers standardized for several sizes become.

Presentation of the invention

The object of the invention is to provide a packaging element for Protection of an object in a rigid or semi-rigid To create a container with a polygonal cross section against impacts, which avoids the disadvantages mentioned above.

The object is achieved with the teaching described in claim 1 solved. The subclaims name advantageous refinements the teaching of the invention.

That according to claim 1 from a multiple folded template Packaging element formed has one of the material and elasticity depending on the type of folding. The through the spring travel provided by the spring parts reduces the abrupt deceleration of the object when struck. The acceleration forces to which the object is exposed consequently decrease. The packaging element is closed capable of regeneration and therefore not only protects once.

An adaptation to different gaps is by several Types of folding the packaging element in a simple manner given because the spring parts are folded several times. The vote of the material is mainly taking into account the Forces occurring during transportation. Preferably the folding should be done by hand, but also simple technical aids can be used. Sheet metal, paper or paper-like materials come as materials Material, e.g. B. cardboard, corrugated cardboard or laminates in question.

The packaging element can be used both to cushion impacts with a vertical component also serve as cushioning of bumps with a horizontal component.  

A packaging element according to claim 2 is preferably used for Cushioning of vertical shocks. It will be between the Object and the cover of the container stuck. For It can cushion impacts with horizontal components between the object and a side wall of the container be put.

The development according to claim 3 discloses a Packaging element for special protection against horizontal Bumps with two sides of the object Spring elements. Both spring elements spring in the same Direction. By arranging two crosswise Packaging elements is a horizontal all-round protection of the Given object. The packaging element can also be used a packaging element for vertical protection work together.

The packaging element according to claim 4 combines the vertical protection with protection in a horizontal Direction through the design of three spring elements. Two Spring elements enclose the object laterally and one is located above.

In claims 5 to 7 are template forms for production of the claimed packaging elements. The Training according to claim 5 comes with a strip-shaped Template for the production of a packaging element with vertical protection.

A packaging element according to claim 6 can be from a Fold the H-shaped template with each of the four legs of the H an initially vertical spring part results. The two each Spring parts on each long side of the H form one Spring element, which are folded and an object Include on the side.  

A packaging element according to claim 7 for achieving a horizontal and vertical protection is one Template can be produced. The template has the shape of an H, where however between the two long sides with two legs each a fifth and sixth leg is attached. The four outer legs become horizontal spring parts the two middle spring parts are folded and folded folded into vertical spring parts. It thus arises three spring elements.

With the development according to claim 8 is a residual cushion effect achieved by the elasticity of the material itself. After folding the spring element, the corrugated cardboard springs in itself further together, reducing the acceleration forces can be further reduced. Folding the strip vertically to the direction of the corrugation increases the stiffness of the spring parts. Embossed folds on the strip make folding easier.

With the training according to claim 9, the travel of the Spring elements through several folds of the spring parts enlarged and thus acceleration forces on the object reduced. However, not all possible folds need to be made be made. Rather, it is conceivable to Adapting the size of the object to dispensing with folds, here in particular the last fold.

If according to the training according to claim 10, the two Touch spring parts on at least one fold before the Spring parts are pressed flat together, this stiffens Measure the packaging element. Physically increased thereby the spring rate of the packaging element and that mutually supporting the spring parts before their complete Pressing together corresponds to a progressive one Spring behavior.  

In order to expand the area of application of the packaging element, it is designed in accordance with the further development according to claim 11, that it's easy for different distances between the object and the wall of the container can be used. In particular, this is the last one Section provided, which erected to the rigid element becomes. The last section set up is by the Edge area folded parts stabilized so that it is a U-shaped profile adopts. So that the two folded Do not kink parts under the load, grasp insert them into recesses on the penultimate section. The last section preferably has folds at the edge distance the slots of the before last section to facilitate the Buckling on.

The packaging element according to the training according to claim 12 completely and completely covers the object in the container offers additional protection against dirt. The The middle section corresponds in length and width to Inner dimensions of the container.

The packaging elements are particularly suitable for the arrangement above the object in the container. You can therefore as Head part of a multi-part packaging can be viewed. Because of of compression under load, they are only in as a foot part suitable in special cases, since the object is then no longer remains spatially fixed in the container. To the area of application expand and a suitability both as headboard and as Manufacture foot part, give the training according to Claims 13 to 15 solutions for fixing the object in a packaging element.

The training according to claim 13 improves the adaptation of the middle part with curved contact surfaces of the packaging object. The middle section points to this Longitudinal cuts, which are over the first kink  extend beyond the first fold. This will make the increase in length caused by the curvature balanced when the object dips into the middle part. The packaging element must be arranged so that the direction of the Longitudinal sections with the main direction of curvature of the contact surfaces of the item matches.

In another way, the object is by a claim 14 further developed packaging element stabilized. Here the middle part has recesses into which the Object protrudes. This will cause it to slide sideways prevented.

In the training according to claim 15 can be from the Fold out the middle section that stops the object in its Limit freedom of movement and keep him in the container determine spatially.

In claim 16 is a suitable as a foot part packaging element described. For objects with curves, in particular shut-off valves with flange connections is a Packaging element of advantage, which is due to the rounding adjusts, but still moving the object lengthways avoids the rounding. Through the longitudinal cuts in the The item is partially immersed in the packaging element and the individual strips line up with the curve. In the packaging element remains unchanged in the environment and the other bands leave a paragraph, which is an obstacle to shifting. Like the one above described packaging element is a material such as Sheet metal, paper or paper-like material, e.g. B. carton, Corrugated cardboard or laminates for making this Packaging element. Corrugated cardboard should preferably be used come, which is to be folded perpendicular to the direction of the corrugation.  

When the object is deflected into an elastic head part the packaging lifts the object from the foot part, but falls back again and is within the foot part again of the incised area. The situation before and after the shock doesn't have to be the same. The foot section fixes the Subject also elsewhere.

The training according to claim 17 leads to an improvement the adaptation of the packaging element to the curve of the Object and stabilizes the object more advantageously Wise.

Ways of Carrying Out the Invention

To be too high, for example with a shut-off valve Avoid applying force to the actuator and protecting the spindle with the spindle nut becomes a Packaging element according to claims 1 to 8 between the Shut-off valve and the lid or a wall of the container set. Because the one provided by the packaging element Deformation path, here referred to as spring travel, is large a reduction in the acceleration forces achieved. The Accelerating forces on the object can be reduced to one Tenths of the original value.

The packaging element shown in Fig. 1 consists of a multiple folded template in the form of a strip ( 1 ). The width b of the strip ( 1 ) corresponds to the width of the container into which an object is to be packed. The strip ( 1 ) consists of a central part ( 2 ) of length l, from the opposite sides of which the legs ( 3 and 4 ) extend. The leg ( 3 ) consists of four sections ( 3 a, 3 b, 3 c, 3 d), as well as the leg ( 4 ) from the sections ( 4 a, 4 b, 4 c, 4 d), which are shown by dashed lines Fold lines are delimited against each other. The first sections ( 3 a, 4 a) are longer than half the length l and therefore, before they rest on the middle part, meet the edges ( 3 a / 3 b) and ( 4 a / 4 b) when folding over to each other.

The sections ( 3 b, 3 c), as well as the sections ( 4 b, 4 c), are either as long as the first sections ( 3 a, 4 a) or shorter. The last sections ( 3 d, 4 d) are the shortest because they are intended for different functions. The penultimate sections ( 3 c, 4 c) are each provided with two slots ( 5 a, 5 b, 6 a, 6 b), the width of which is greater than the thickness of the template. They extend over a length which corresponds to their distance from the edge of the sections ( 3 c, 4 c), away from the last fold line and parallel to the edge. The last sections ( 3 d, 4 d) are cut on the fold line to the penultimate section ( 3 c, 4 c) to the slots ( 5 a, 5 b, 6 a, 6 b) from the edge so that wings ( 7 a, 7 b, 8 a, 8 b) arise. In the extension of the slots ( 5 a, 5 b, 6 a, 6 b) folding lines are provided which facilitate the folding of the wings ( 7 a, 7 b, 8 a, 8 b).

In FIG. 2, a packaging element is shown in the folded state. From the sections ( 3 a, 3 b, 3 c) and the sections ( 4 a, 4 b, 4 c) spring parts have been created by folding in an alternating direction along the fold lines. The two spring parts together form a spring element which, starting from the central part ( 2 ), extends away from the object to be packaged. The sections ( 3 a, 4 a) meet at the folds to form the sections ( 3 b, 4 b) and form a first stop of the spring travel when the spring parts are deflected under load. The last sections ( 3 d, 4 d) overlap. This type of folding of the template is the smallest practical design of the packaging element.

Further types of folding for adapting the element to objects or containers of different sizes are shown in the following FIGS. 3 and 4. If the last sections ( 3 d, 4 d) are folded over, this means an enlargement of the spring part, ie a larger distance can be bridged between the object and the container. The folds between the sections ( 3 c, 3 d; 4 c, 4 d) can also meet. A further enlargement is achieved by setting up the last sections ( 3 d, 4 d) perpendicular to the central part ( 2 ). In order to stabilize the position of the sections ( 3 d, 4 d), the wings ( 7 a, 7 b, 8 a, 8 b) are folded in until they fit into the slots ( 5 a, 5 b, 6 a , 6 b) can intervene. The sections ( 3 d, 4 d) are supported with their backs against each other.

Another packaging element, which consists of the elements described above, is shown in FIG. 5. Here, spring elements ( 10 , 11 ) are attached to two opposite sides of a rectangular central part ( 9 ). The template for the production of this packaging element is designed in the form of a large H. The spring elements ( 10 , 11 ) are folded as described above and then bent outwards at the connection to the central part ( 9 ). The middle part ( 9 ) is either shorter in its width (b ') or its length ( 1 ') than the corresponding size of the container. This is necessary to provide suspension travel. The width of the packaging element can be adapted to the respective container by means of a kink on the middle part ( 9 ). The object protrudes into the packaging element with one end and the spring elements ( 10 , 11 ) secure this end against lateral impacts. If another packaging element is placed crosswise, all-round protection can be achieved.

Horizontal and vertical protection is provided by a packaging element which can be folded into a shape shown in FIG. 7 from a template shown in FIG. 6. Starting from the template shown in Fig. 5, the middle part ( 9 ) is also provided with legs, which when folded together result in a vertically acting spring element ( 12 ) in the middle part ( 9 ). This packaging element can also be combined with the aforementioned. In the simplest way, a universally usable, reusable packaging element is created.

Another packaging element, which is particularly suitable for fittings with flange connections, is shown in FIGS. 8 to 10. The template shown in Fig. 8 consists of four sections ( 14-17 ) which are divided by fold lines. In the middle sections ( 15 , 16 ), longitudinal cuts ( 13 a, 13 b, 13 c) have been made, some of which still extend into the areas ( 14 , 17 ). This creates several bands ( 18 , 19 , 20 ). If the template is made of corrugated cardboard, the undulating lower layer ( 21 ) must run in the direction indicated. The folded packaging element has the shape of an M, as shown in FIG. 9. The opening angle α of the sections ( 15 , 16 ) set up to inclined surfaces is advantageously more than 90 °.

If, as shown in Fig. 10, a cylindrical object is placed, the loaded bands ( 22 ) lie against the object, whereas the unloaded bands ( 23 ) remain unchanged and form a side stop. Due to the longitudinal cuts ( 13 a, 13 b, 13 c) extending beyond the folds, the straps ( 18 , 19 , 20 ) are lengthened and the object dips deeper into the packaging element. After the compression of the packaging element by the accelerated object, the object falls back into the foot part of the packaging.

Special developments of the packaging element shown in Fig. 1 for stabilizing the object by the packaging element in its position in the container are shown in Figs. 11 to 14. In Fig. 11, the central part is provided with longitudinal cuts ( 24 a, 24 b, 24 c), which extend beyond the first kink to the folds ( 3 a, 4 a). In FIG. 12, the middle part (2) is provided with recesses (25 a, 25 b) is provided, in which the article at least partially extends. In Figs. 13 and 14 are from the center portion stops (26 a, 26 b, 27 a, 27 b, c 27, d 27) can be opened, which include the object partially and prevent it from moving over them. For elongated contact surfaces of the object, e.g. B. hand lever in fittings, the embodiment shown in Fig. 13 is particularly suitable. The hand lever lies between the two stops ( 26 a, 26 b) and can therefore only move in the direction of its longitudinal axis. Lateral evasion is prevented by the stops ( 26 a, 26 b). For round contact surfaces, e.g.

B. handwheels or actuators in fittings, the embodiment shown in Fig. 14 are particularly suitable. The handwheel lies between the circular stops ( 27 a, 27 b, 27 c, 27 d) and is prevented by them from moving sideways.

Industrial applicability

The packaging elements according to the invention are suitable for Pack heavy items, e.g. B. fittings, or part-turn actuators in semi-rigid containers, such as B. Cardboard box. The packaging elements can be used for different objects having spatial dimensions are used are and can be adapted to the respective requirements become.
