The honeycomb structure" or honeycomb material, referred to in the specification and claims and shown in the drawings, is made up of a plurality of open-ended cells which may be of any desired size and shape, for example, hexagonal, circular, ova], or rectangular. Such structure may be formed of any desired material, for example, paper, cloth, metal, or the like. However, since all or a portion of the structure must be compressed into accordion shape to act as a resilient cushion, it has been found preferable to construct the structure of paper or paperboard.
The paper honeycomb structure may be produced by superimposing sheets of paper upon each other until a thick stack is formed, each sheet of this stack being held to the one above it, by adhesive or other means, along spaced and generally parallel lines, with the lines on one side of each sheet between the lines on the other side of said sheet. it will be seen that the distance between such lines determines the cell size. By cutting this stack either at a right angle (Figure l) or at an oblique angle (Figure 1a) across the lines holding the sheet together, pieces may be obtained of a length corresponding to the desired thickness of the honeycomb structure to be used for the pads shown in the various figures. The thickness of the pad may be varied and is dependent upon several factors, such as size, weight and the use to which it will be put. These pieces are then expanded into the shape and form shown in Figures 1 and la. it will be understood that the cell wall thickness depends on the weight of paper used. Since the honeycomb structure varies with both the cell wall thickness and cell size, these may be varied to meet practically any requirements. Where additional rigidity or strength is required or where the pad is used in places where it will be subjected to high humidity or moisture, which softens and weakens the paper, the paper may be impregnated or coated with resin, sulphur, metal or similar products. This may be done prior to the forming of the paper into the honeycomb structure or after. it has also been found that greater resiliency can be imparted to the compressed structure if the paper or honeycomb material is impregnated with resin before placing it under compression.
Where the honeycomb structure is to be made of other materials, for example, cloth or metal, other known methods may be used to construct the desired structure. It will be understood that the honeycomb material it self and the method of manufacturing it are well known and are therefore not specifically claimed herein.
Referring more particularly to the drawings there are shown in Figures 1 and la pieces of honeycomb material constructed as heretofore described. This material is made up of walls 21 which form a plurality of open ended cells 22. Such material is placed in a press with the plates resting against each face of the material. The uniform application of pressure to the top plate causes the walls of the cells to assume an accordion shape, such shape occurring first at the top of the walls and moving gradually down the walls as long as the pressure is applied. It is possible merely by controlling the pressure to obtain the accordion shape for any depth desired. The depth of the accordion shaped cushion is dependcut on the weight of paper used for the structure and also on the pressure applied. Figures 2 to 5, inclusive, illustrate the effects achieved by so compressing the honeycomb. Figure 2 shows the piece of honeycomb of Figure 1 after the walls have been compressed to their full depth. Figures 3 and 4 illustrate the same results on a full pad, the pad of Figure 3 having facing sheets 23. While such facing sheet is not essential, it serves in some cases to hold the honeycomb in expanded form and give it additional rigidity and strength. Figure 4a illustrates a portion of a pad in which the honeycomb of Figure la has been so compressed. Figure 5 shows a pad similar to that of Figure 3 but with the walls compressed for only a portion of their depth, so that there remains beneath the accordion shaped honeycomb a portion of the honeycomb which is still in its original condition. The accordion shaped portion is designated as 21a and the portion under it still in its original condition as 21b.
Since the compressed accordion shaped honeycomb (Figure 2) is resilient and springy and the honeycomb in its original condition (Figure l) is strong and rigid, it will be seen that it is possible to form a pad which possesses the features and characteristics of both. In other words, where the demand is for only a cushion or cushion effect, the pad of Figures 3, 4 or 4a may be used, but where such cushion must be further protected and reinforced, the pad of Figure 5 will efiiciently serve the purpose, as will be evident from the drawings and supporting description which follows.
Figures 6 and 7 show a pad, similar to that of Figure 5, which is ideally suited for shipping fragile products. This is made up of honeycomb material with the walls compressed for only a portion of their depth. In addition the pad has been scored across the corners along lines 24 with a V-shaped die, so that the corners can be turned in at right angles to the center portion of the pad. If such center portion conforms in size to a product being packaged, it will be seen that the turned in corners serve to protect such product not only on the end faces but also on the other sides. It is clearly shown in Figure 7 how a pair of these pads may be employed as a support for shipping a small radio. If the radio and end pads are slipped into a carton of proper size, the radio is firmly held in position away from all sides of the carton. This prevents it from moving in any direction and eliminates the necessity for the corrugated board members which are usually bent into various forms and placed around such products when they are shipped. In addition to the supporting effect the accordion shaped honeycomb acts as a cushion to absorb all shocks or knocks which the package may receive during shipment. Furthermore, the facing sheet 23, which comes in contact with the radio or other product held between the pads, may be of suflicient softness so as not to mar or scratch the surface of the product.
Figure 8 shows a modification of the pad of Figure 6, which is likewise particularly adapted for shipping fragile products. This is made up of a honeycomb structurehaving walls 21, open ended cells 22 and a facing sheet 23. This sheet and the honeycomb structure beneath it are cut along the lines 25 to a depth approximately equal to half the thickness of the honeycomb. Such cuts define a rectangular shape correspond ing generally to the end of the small radio shown in Figure 12. It will be understood that the cut-out portion may be of any shape necessary to receive any other type of product being shipped. In addition to the cuts 25 there are diagonal cuts 26 made in each corner of the rectangle. Thereafter a die having beveled corners is placed over the cut-out portion and pressure is applied, which results in the picture frame effect shown in Figure 8. Referring to Figures 9 and 10 it will be seen that the central portion 23a is uniformly depressed to the desired depth and that the flaps 23b slope in from the plane of the facing sheet 23 to the plane of the depressed portion 23a. This particular construction is particularly useful where the product to be shipped has a delicate finish which might be marred by coming in contact with the honeycomb material itself. It will be seen that the flaps 23b serve to protect the corners of the product, whereas the depressed portion 23a protects the flat side of the product.
Figure 11 shows a modified form of pad in which the cuts 25 are made as they were in the case of the pad of Figure 8, but the cuts 26 and flaps 23b are omitted. The die used in this instance has square corners instead of the beveled corners on the die used for the other pad. Therefore when pressure is applied the central portion 23a is depressed, exposing the honeycomb structure between the plane of the facing sheet and the plane of the depressed portion.
In the pads illustrated in Figures 8 to 11, inclusive, it will be noted that such depressed portion forms an ideal recess to receive the product being shipped. It has been found that the application of pressure to the cut-out portion 23a results in compressing the honeycomb structure so that the walls directly beneath the cut-out portion assume the accordion shape shown in Figures 10 and 11. As in the case of the pad of Figure 5, such accordion shape extends only for a portion (21a) of the thickness of the pad so that there remains beneath such accordion shaped honeycomb a portion (21b) which is still in its original condition. Thus the honeycomb structure beneath the cut-out portion retains in part not only the rigidity and strength characteristic of such material but also has the resiliency and springiness resulting from the accordion shaped cushion formed beneath the cut-out portion.
It will be seen from Figure 12 that a pair of the pads similar to the form shown in Figure 8 likewise make an ideal support for shipping a small radio. In this case the pads are placed over each end of the radio and the pads and radio are then slipped into a container or carton 27 of suitable size. The radio is thus firmly and securely held in position and is cushioned against any jars or shocks which may occur during shipping. It will be noted that the flaps 23b prevent the rounded corners of the radio from coming in contact with the honeycomb structure itself so that there is no danger of such honeycomb structure scratching or marring the finish of the radio.
One product which has been found most difficult to ship because of its fragile nature is the electric meter made up of a metal base and a glass shell, which houses a delicate mechanism. The general configuration of said meters is shown in Figure 17, the glass shell being designated as 28 and the metal base as 29. Referring to Figures 13 to 17 inclusive it will be seen how the pad of the present invention may be adapted for packaging such product. A rectangular piece of honeycomb material provided with facing sheets 23, shown in Figure 14, is cut along the lines 30 to a depth approximately half the thickness of the honeycomb structure. The narrow strips 230 of the facing sheet between these lines 30 and the honeycomb beneath as shown in Figure 15, to the proper depth to receive the base edge of the meter. Thereafter the opposite side of the honeycomb structure is cut along lines 31 to the full depth of the honeycomb structure without, however, cutting the top facing sheet 23. This results in a series of rectangular pads 32 which are hinged to gether merely by the top facing sheet, as shown in Figures l3 and 16. The depressed portion of this pad serves as a recess to receive the metal base of the electric meter so that a pair of electric meters can be rolled up face to face in this pad in the manner shown in Figures 16 and 17. This rolled up pad can then be placed in a container or be properly wrapped and tied or taped to complete the package. It has been found that electric meters so supported by a pad of the present invention can be dropped from a considerable height on a concrete floor without breaking or damaging them. Again, as in the case of the radio, the depressed portion serves as a recess to hold the meters in place while the accordion shaped honeycomb under such depressed portion acts as a resilient cushion to absorb any shocks im parted to the package.
A modified form of construction likewise for packaging such meters is shown in Figures l8, l9 and 20. In this case a pad, similar to that shown in Figure 14, is likewise cut along lines 30 and the strip 23c between such lines is depressed. Thereafter the pad is scored along lines 33 with a V-shaped die so that the pad assumes the configuration shown in Figure 19. By using a pad so scored it is possible to roll up a pair of meters into a package having a fiat and smooth outside face, such as that shown in Figure 20. A corrugated sheet may be slipped into each end and it is then necessary only to tie or tape up the package without additional wrapping or container as called for in the construction shown in Figure 16.
The honeycomb structure illustrated in the drawings other than Figures 1a and 4a was made by cutting the stacked sheets at right angles across the spaced and parallel adhesive lines and then expanding the cut-E piece. Such structure with the faces disposed normal to the cells has great strength and rigidity. On the other hand Figure 1a shows the effect created when the stacked sheets are cut at an oblique angle across the adhesive lines. When this structure is compressed, as shown in Figure 4a, the same accordion shaped folds are obtained, but the folds overlap slightly. This tends toward a better cushioning effect and gives a larger exposed area on each face. It may be stated generally that as the angle of the cells from normal is increased, the strength and rigidity is decreased and the cushioning effect is increased. This allows a greater cushioning effect from the same weight of paper.
The pads and the particular products supported or packaged in such pads, illustrated in the drawings and heretofore described, may be taken as representative of the many variations and modifications which are possible within the principle of the invention. It will be seen that the honeycomb material may be compressed into accordion shape to form a pad having a resilient cushion over all or a portion of the pad, and may be compressed into accordion shape for any thickness to provide a completely resilient cushion or a resilient cushion backed by a rigid honeycomb structure; that the pad may be cut to any desired size and thickness; that the pad may be cut, scored and shaped to be fitted around a product being packaged; and such pad may be provided with a recess to receive a product, such recessed portion being cushioned.
Where a heavier product with a greater impact is being shipped, the pad compressed for a portion of the depth will usually be more suitable since it furnishes a cushion effect and a greater resistance effect. On the other hand the lighter more fragile product with less impact should such strips are depressed,
in Figures 3, 4 and 4a in most cases be packed with a pad compressed for the full depth since this provides a greater cushion efiect and a lesser resistance effect. In all cases the pad must be selected to satisfy the particular requirements for the product and the conditions under which it must be shipped. Although the pad of the present invention may be used in conjunction with a container, for example in packaging a product in the manner shown in Figure 12, it will be understood that in some instances the pad may be appropriately scored and folded so that no extra container is necessary, for example in packaging a product in the manner shown in Figure 20.
It has been further found that pads of the type shown possess sufiicient resiliency and strength that they be used in place of or as a supplement to the springs in upholstered chairs, automobile seats and the like. In any cases where it is necessary to minimize or reduce shock or jarring, the pads of the present invention will prove most useful.
Since certain changes may be made in the above product and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
It is also to be understood that the following claims are intended to cover all the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
