Padding for an item to be wrapped

Description

[0001] The invention relates to a cushioning part for cushioning an object to be packaged in an outer carton.

[0002] Such cushioning parts are generally known in the prior art. The cushioning parts typically consist of at least one basic element, which is constructed as follows: It consists of a base body in the form of a downwardly open half-tube and at least two hump-shaped support elements, which are inserted on the outside of the half-tube, visibly facing each other there, and project upwards on the outside of the base body with a height H beyond the high point on the inside of the downwardly open half-tube. The opposing surfaces of the hump-shaped support elements and their transition to one another on the outside of the downwardly open half-tube are shaped such that together they form an upwardly open channel section.The entire upholstery part, in particular each of the basic elements, is made in one piece from a recycled paper fiber material with an average wall thickness; see the applicant's website.

[0003] The invention is based on the object of developing such a known cushioning part and a packaging with an outer carton and with the said cushioning part in such a way that the rigidity of the cushioning part is increased in a direction transverse to its longitudinal axis.

[0004] This object is achieved for the claimed upholstery part by the subject matter of claim 1. Accordingly, the low point on the inside of the upwardly open channel section is spaced by the distance h, with h > being the simple wall thickness of the upholstery part or the base element, from the high point H1 on the inside of the downwardly open half-tube.

[0005] The claimed design of the distance h offers the advantage that it significantly increases the rigidity of the base element and, if applicable, also that of the cushioning part, particularly in a direction transverse to its longitudinal axis L. Furthermore, the cushioning part according to the invention is not more expensive than Styrofoam, but unlike Styrofoam, it is recyclable because it is made from waste paper.

[0006] According to a first embodiment of the invention, this rigidity is particularly good or high when the distance h is greater than or equal to twice the wall thickness. At the same time, it is preferable to ensure that the distance h is not chosen to be greater than the height H, to ensure that the transition between the opposing support elements does not exceed the height H of the support elements themselves above the highest point H1.

[0007] Such a basic element according to the invention can in principle be of any desired length, wherein the length is preferably adapted to the length of the object to be packaged.

[0008] The terms "bottom" and "top" and accordingly the terms "bottom" and "top" refer to the Figure 1 and 2 shown arrangements of the upholstered part or the basic element in the room. What is Fig. 1 can be seen in a top view of the base element, forms its upper side. From the underside of the base element, Fig. 1 only a few areas are visible, as far as they can be seen through the cut-open hollow support elements. Fig. 2 shows the underside of the upholstery part Fig. 1 .

[0009] The above-mentioned object of the invention is further achieved by a packaging for the object to be packaged, said packaging comprising an outer carton and at least one cushioning element according to the invention inserted into the bottom of the outer carton on an inner side thereof for defining and delimiting a receiving space for the object to be packaged within the outer carton. The advantages of this solution to the problem correspond to those mentioned above with reference to the claimed cushioning element.

[0012] The invention is described in detail below with reference to the figures mentioned in the form of exemplary embodiments. In all figures, technical elements are designated by the same reference numerals.

[0013] Figure 1shows the cushioning part 100' according to the invention for cushioning an object to be packaged in an outer carton, wherein the cushioning part here consists of only one base element 100. The base element has a base body in the form of a downwardly open half-tube 110, on the outside of which hump-shaped support elements 120 are attached, which are arranged opposite one another in pairs and which project upwards beyond the downwardly open half-tube 110. Between the respectively opposing surfaces 122 of the hump-shaped support elements 120, a transition 130 is formed, which, together with the opposing surfaces 122 of the support elements 120, forms an upwardly open channel section. Along the longitudinal axis L of the downwardly open half-tube, a plurality of these pairs of support elements are arranged next to one another at preferably equidistant intervals a. The entire Figure 1The upholstery part shown, ie here the one basic element 100, is made in one piece from a waste paper fiber material with an average wall thickness W. In Figure 1 The total width GB and the total length GL of the cushion part of the base element are also shown. Finally, the low point T can also be seen on the inside of the upwardly open channel section 140. The viewing directions or views of the wide side, the long side, and the top side are marked with the arrows AB, AL, and A0.

[0014] Finally, it can be seen that the support elements 120 are each designed as hollow bodies, and that the wall of the bottom-opening half-tube is perforated in the area of ​​the hollow support elements, so that the bottom-opening half-tube and the support elements define a common hollow space 112 that is open downwards and is delimited by remaining, unperforated wall sections 114 of the bottom-opening half-tube, which are arranged opposite one another in pairs. The hollow body design offers the advantage of weight savings and stackability of the basic elements.

[0015] Figure 2 shows the basic element in its first embodiment according to Figure 1in a perspective view from below. After the formation of the hollow support elements 120, only the said wall sections 114 remain of the original half-pipe. The individual wall sections 114 are arranged in pairs opposite one another and are spaced apart in the longitudinal direction by the said transitions 130 of the opposing support elements 120. In addition to the wall thickness W, Figure 2 also a high point H1 can be seen on the inside of the half-pipe 110. In the "normal view" according to Figure 1 the high point H1 represents the vertex; when viewing the bottom side according to Figure 2 The vertex H1 logically symbolizes a low point of the upwardly open half-pipe 110.

[0016] Figure 3 illustrates once again in its center a top view of the Figure 1known basic element 100. The view to the left shows a section through the basic element at point III-III. To the right of the top view is the view of the right end of the basic element. Above the top view, a section through the basic element along the longitudinal axis L can be seen. This sectional view shows not only the aforementioned high point H1, which corresponds to the apex on the inside of the downwardly open half-tube 110, but also the low point T of the upwardly open channel section 140. Furthermore, a vertical distance h between the high point H1 and the low point T is illustrated. According to the invention, this distance is greater than one times the wall thickness W, preferably it is chosen to be greater than or equal to twice the wall thickness W, in order to sufficiently stabilize the cushioning part in a direction transverse to its longitudinal axis L for possible impact loads.In addition to the vertical distance h, the total height GH of the base element and the height H of the individual support elements above the high point H1 are also illustrated. Finally, the aforementioned sectional view shows the distance a between adjacent pairs of the hump-shaped support elements in the longitudinal direction L of the base element 100.

[0017] Figure 4 Finally, FIG. 1 illustrates a second exemplary embodiment of the base element 100 according to the invention or the cushion element 100', which differs from the previously shown first exemplary embodiment in that a filling element 150 can be formed above the transition 130 between the opposing support elements 120. This filling element 150 typically connects the two opposing support elements to one another. Alternatively or additionally, such a filling element can also be formed on the underside of the base element between visibly opposing wall sections.

[0018] The formation of the filling elements 150 advantageously further stiffens the base element in a direction transverse to the longitudinal axis L. The filling elements 150 are advantageously also formed as hollow bodies with a wall thickness W, and at the same time, the transition 130, which serves as the base of the filling element, is typically also perforated. The filling element is typically formed integrally with the base body and the support elements, with the same average wall thickness w, from the same recycled paper fiber material. When formed as hollow bodies and in the shape of a truncated pyramid, the filling elements 150 enable easy stacking of the base element 100.

[0019] Figure 4 shows the filling element 150 in the form of a bulge 152. In the form of this bulge, the filling element protrudes beyond the outside of the downwardly open half-pipe. Alternatively, it can also be realized in the form of a dent 154, as in Figure 8 shown. As a dent, it projects into the cavity 112 spanned by the downwardly open half-pipe 110. The bulges 152 and the dents 154 can be formed alternately in the longitudinal direction L of the downwardly open half-pipe 110; see also Figure 8 Unlike in the Figure 4 and 8 As shown, the filling element 150 can also be formed with a smooth, ie edge-free transition to the support elements and / or the transitions 130.

[0020] The filling elements 150 on the upper side of the base element 110 between the paired projecting support elements and / or the filling elements on the underside of the base element between the paired opposing wall sections, not shown in the figures, can also be arranged alternately in the longitudinal direction of the base body 100.

[0021] Figure 5shows the second embodiment of the basic element 150 according to the invention according to Figure 4 from underneath.

[0022] Figure 6 shows that Figure 4 known basic element in a cross-sectional view, cut in the plane VI-VI. The Figure 3 already known dimensions, such as h as the vertical distance between the high point H1 on the inside of the half-pipe 110 and the low point T on the top side of the transitions 130, the height H of the individual support elements 120 above the high points H1 as well as the total height GH of the base element 100 are for the Figure 4 and 6 The second embodiment shown is identical. In addition, the Figure 6The height HF of the filling element 150 above the transition 130 is illustrated. The filling element 150 is also manufactured with the average wall thickness W. The following preferably, but not necessarily, applies to the height HF: h + HF ≤ HD h. Optionally, the filling elements can project beyond the support elements.

[0023] Figure 7 illustrates a third embodiment of the cushioning part 100' according to the invention, in which a plurality of, for example, three basic elements 100 are arranged parallel to one another. The entire cushioning part 100' is made in one piece from the said waste paper fiber material. The filling elements 150 are here, as in the second embodiment according to the Figure 4 - 6 each realized in the form of a bulge 152, wherein the bulge protrudes beyond the outside of the downwardly open half-pipe. Figure 7In the third embodiment shown, it is also worth mentioning that the basic elements each stand on the ground with their downwardly open half-tubes and abut each other with their long sides. Figure 7 The arrow AL shows the view of the long side of one of the basic elements 100.

[0024] Figure 8 illustrates a fourth embodiment of the cushion part 100' according to the invention, in the form of a base element, wherein the filling elements 150 between the support elements 120 are alternately realized in the form of a bulge 152 and a dent 154. This design of the filling elements also means an increase in the rigidity of the cushion part in a direction transverse to the longitudinal axis L.

[0025] For all embodiments of the cushion part according to the invention and the basic element according to the invention, it is the case that its outer dimensions are preferably cut in a cuboid shape, as shown, for example, in the Figure 1 shown.

[0026] Figure 9 illustrates a fifth embodiment of the cushion part 100` according to the invention, wherein two basic elements 100 are connected to each other at a predetermined angle, here for example 90°, to form the corner element 160. In Figure 9The two connected base elements 100 are shown standing on their wall sections 114. Alternatively, the corner element could also be formed by connecting the two base elements 100 lying on their longitudinal sides. Purely theoretically, a third alternative would also be to connect the two base elements 100 at the end faces of their respective downwardly open half-tubes.

[0027] Figure 10 illustrates a packaging 200 for, for example, a rectangular object 210. The packaging according to the invention comprises a cuboid-shaped outer carton 220 and at least one cushioning part 100' inserted on its inside on its bottom, according to the present invention. The cushioning part on the edges of the outer carton defines and delimits a receiving space 230 for preferably precisely receiving the object 210 to be packaged within the outer carton 220. Figure 10 shows that the cushioning elements 100' according to the invention, or the base elements 100 according to the invention, are used in various embodiments for packaging the object 210. Thus, they are inserted in the form of the aforementioned corner elements 160 in the four corners of the outer carton 220, and on the long sides they can be used either as a single base element or in multiple parallel arrangements of individual base elements, depending on the outline of the object to be packaged.

[0028] The Figure 10 A third embodiment of the cushion part 110` according to the invention, which is also installed and in which three basic elements with parallel longitudinal axes are connected to one another, is shown in Figure 11in a modified form with four parallel basic elements, shown enlarged. In this sixth exemplary embodiment of the upholstery part according to the invention, the basic elements 100 are arranged parallel to one another on their longitudinal sides or on their support points. They are then connected to one another either by their opposite wall elements 114 or by their opposite support elements 120. In this respect, it represents an alternative to the Figure 7 known embodiment of the cushion part 100', in which the basic elements 100, which are also arranged in parallel, are connected to one another there with their longitudinal sides facing one another, as mentioned.

[0029] Figure 12shows a seventh exemplary embodiment of the cushion part 100' according to the invention, or base element 100, in which two support elements 120 adjacent in the longitudinal direction L are connected to one another on the same side of the half-tube 110 via a rib element 170, and wherein the rib element 170 extends a short distance into the upwardly open channel 140. Preferably, the rib elements 170 are formed in the longitudinal direction L of the base element 100 alternating between two left-side and two right-side support elements 120. The terms right-side and left-side refer to the direction of the longitudinal axis L, as in Figure 12 shown.

[0030] In this seventh embodiment of the base element according to the invention, the two support elements 120 together with the rib element 170 arranged between them form a hollow space. The rib elements 170 are also preferably tapered upwards, so that the Figure 12 The basic element shown is advantageously stackable.

[0031] Figure 13 illustrates the seventh embodiment according to Figure 12 with a view from below. Here you can see that in the first embodiments according to the Figure 1 - 4 existing wall sections 114 of the original downwardly open half-pipe 110 are no longer present at the locations of the support elements 170. Rather, the rib elements 170 in the width direction can also be interpreted as the original wall elements 114 turned upwards. Figure 12 and 13In the seventh exemplary embodiment shown, the support elements 170 each protrude, for example, only to the middle of the upwardly open channel section 140. The support rib element 170 protruding on the top side into the upwardly open channel section 140 can also be opposed by a rib element 170' on the underside in the width direction. This rib element 170' on the underside typically also protrudes only halfway into the half-tube 110 in the width direction and then merges into the rib element 170 on the top side. The rib element 170' can be interpreted as a special form of the design of the original wall section 114. The rib elements 170' are preferably tapered towards the bottom, so that the base element can also be stacked with these rib elements 170'.

[0032] Finally, it should be mentioned that the rib elements 170 on the upper side and the rib elements 170` on the lower side of the base element 100 can be arranged alternately in the longitudinal direction thereof, as shown in the Figure 12 and 13 shown.

[0033] Fig. 14shows an eighth exemplary embodiment of the upholstery part according to the invention, in which at least some, preferably all, of the support elements 120 arranged opposite one another in pairs are aligned and arranged in a V-shape at an acute angle α to the longitudinal axis of the strip-shaped upholstery part. The transition regions 130 and, if applicable, also the filling elements 150 are preferably also V-shaped. If a plurality of support elements 120 arranged opposite one another in pairs are arranged adjacently in the longitudinal direction L on the strip-shaped upholstery part, their V-shaped alignment preferably, but not necessarily, points in the same direction. The same also applies to the V-shaped transition regions 130 and filling pieces 150. An alignment in the same direction offers the advantage that the support elements 120 can then be arranged closer together, for example, overlapping or nested.

[0034] Fig. 15shows the eighth embodiment of the cushion part according to the invention according to Fig. 14 in detail. Due to the V-shaped arrangement of the support elements 120 as well as the transitions 130 and, if applicable, also the filling elements 150, an occurring force F, such as would be exerted upon the strip-shaped cushioning part transversely to its longitudinal direction if the packaged object were dropped, is advantageously not transmitted directly to the packaged object. Instead, the V-shaped support elements 120 form a predetermined crumple zone, which at least largely absorbs the acting forces through its own deformations in the bending area and in the interior of the cushioning part. Advantageously, no damage is then caused to the packaged object. List of reference symbols
