Patented Aug. 19, 1941 UNITED STATES PATENT OFFICE PACKING George T. Henderson, Sandusky, Ohio, assignor to The Binde & Bauch Paper Compansn Sandusky, Ohio, a corporation of Ohio Application April 8, 1940, Serial N0. 328,552 V ICI. 206-46) 3 Claims.
This invention relates to a reinforced packing case for packaging and shipping various articles of commerce and particularly intended for use in the furniture trade, whereby a corrugated board carton may be employed for packing such pieces of furniture er articles in the box in some definite and fixed position. F01 instance, the piece of furniture or article may be so located in the case that all finished surfaces are fr-ee from contact with the sides cf the case, and such articles as need to be supported off I;he bottom and cut of contact with the Walls and top cf the case may be so supported. Davenports, chairs, and tables are some examples cf such pieces although these articles are merely exemplary since the invention is applicable to various other articles cf furniture. The we ight cannot be allowed t rest on the 1egs because of possib-ility of damage to the legs and to the furniture frame generally, and also because concentration of Weight on the corrugated board a1: four small spots is undesirable. Various expedientg are now employed to fores'tall this danger; for example one common means is to use a wood frame or saddle er other built-in structure cf wood er fiberboard under the frame; or very thick pads cf corrugated board a-re bui1t up from the bottom of the case 110 the cross bars of the furniture to take the weight off the legs, and so on. One cf the chief disadvantages lies in the fact that these prior deviceg are not sufficiently flexible to be used for a. variety of different; articles. Furthermore some previous methods require a difiereno size bcix for each different sized article. Y
This invention aims to provide an interior support especially adapted to be used in 1arge as wel1 as sma1l cases, particularly those made cf corrugated board or similar materials, to avoid the difficulties outlined above. The invention is also particularly applicable as a top and bottom strengthening element in such packing cases, either With or without another such support intermediate the height of the case.
An example of a preferred embodiment of the invention is illustrated in the drawing and described in detail below, it being understood that the invention may be used in other forms applying the same principles, all within the scope cf the claims.
In the drawing:
Fig. 1 is a perspective view of a case 1:0 Which the invention is applied, the outside being partly broken away 120 Show the interior better;
Fig. 2 is a transverse vertical section on plane 2-2 cf Fig. 1, showing a davenport in dotted lines therein; and
Fig. 3 is an enlarged vertical section on plane 33 of Fig. 2 omitting the davenport.
The case shown in Fig. 1 is one suitable f0r a davenport II, shown in dotted lines in Fig. 2 only, and comprises a corrugated board structure I2 having a top closu-re conventionally shown aus consisting of inner part laps I3 at the ends and outer abutting half laps I4 at the sides, the joint of which may be taped according to th-e present practice, although the tape i-s not shown. The bottom closure is also conventional, and may conveniently be a repetition cf the top.
My invention is shown applied 8;s a supporting brace at; 20 and as a top brace at 2I. The members are attached the Same way in both instances, and could be cf identical construction, although in the present embodimeni; slight difierences are illustrated between 20 and 2I. Crresponding reference characters, distinguished .by primes, are used for corresponding parts. End bars 22 and 25 are placed horizontally and edge up in corresponding inner and outer positions agatinst Walls such as the ends 23 of the case I2. The inner bar-s 22' have slats 24 fastenecl to their upper edges at appropriate spacing, a.s many slats being used as may be needed, anal the length being enough 1:0 make a snug fit in the case. When the brace i-s in place the outer bars or clamps 25 are applied outside the respective end Walls, opposite the inner bars 22, and. fastened by screws 26 which pass through the end Walls into the bars, Fig. 3. The screws are sei; up tight enough to pinch the corrugated board material cf the ends 23, as shown in Fig. 3. The arrangement is the same at both ends. Although wood is illustrated as the preferable material for my improved brace other materials of construction, such a.s metal and bolts, are within the purview of the invention.
By reason of the clamping action, forces applied to the brace' in any directi0 n are distributed over a wide area of the case wall both inside and cutside, and a tight and extensive frictional hold 1s given, Which is aided by the shouldering effect on the corrugated board be1ow the clamplng bars, in addition to some support by the screw shafts throueh the Wall 23.
A davenport II is indicated in dotted lines in Fig. 2 showing how such an article is placed With its frame 30 supported on the brace 2I'I, which is spaced at a height from the bottom of the case I 2 to clear the feet from the bottvom. A chair er other article could be packed in similar manner.
of course islacing the supports et suitab1e height. It will be understood by those skilled in the art that to hold such article entireiy clear of the Gase Walls the furniture could be secured to the s1ats 24 by screws 0r bolts iiito the underside 01 the furniture.
When place-d at the top of tne case es 21, at the proper height 170 bring the slats 24 at the closing leve1* of the t0p, the brace strengthens the top and. safeguards tops of large span from bing broken in, as may occur when other freight is piled thereon. sufficient to use only one s1at 24' at the top instead of two, in which event the immer and. outer bars 22' and 25 Will be mskterially sherter', for
example the length of the cerresponding lower pieces 22 and 25. If consirlered necessary, a brace, inverted, may be used ina similar manner 120 offer protection I01 the bottom cf the case.
By my invention one size of carton can be used to packe variety o1 difierent si zes 01 articles, thus reducing the numoer of differergtsizes cf cartons that must be carried in stank by th8 -shipper 01 manufacturer. A still iurther advantege is that the strips 25 011 the 0utside 0f the box provide excellenthandles making it unnecessary to cut hand hqiesin-the box, apply metel er rope handles 01 the like, and tha/t L-y such handles the support during carrying Qiflfl handling is transmittecl -directly 130 the article rather than through the Walls of the cqntainer. v
Inasmuch as the top brace f2 1 srts the clos ure laps, such brace niakes -it possible 130 cement the 1aps I3,E shut insteed of using-tape er special stitching:mechines, whieh are ex e ensive than the i.is'e cf edhesive. In additien, adhesive sealing results in a much more rigid box top b-ecause the inner andouter laps arte bondeci together over extensive areas, whereas when sealed W'1th tape er stitching there is a certain amount cf weaJving er- Wrackin 0f the box top resulting from movement between the immer and outer laps.
lt Will be seen irom the foregeing tha-t I have invented a packing-cievice which is adapted te be used in corrugated beard am} like ca1tons of all sizes, and is .particularly advantageeus in lauge size cases, which requires 110 modifxcation. ef ordinary carton shapes; Which cgmbines strength,
simplicity, ch zipness ease of application and great stvength;v Which distributes tl1e lcad anal es avoids concentrated stresses; which can readily be removed and .re-used; Whih may easily be made with simple tools; requires 210 sp'ecial skill for its assembly; may b e made in a variety of detailed shapesarid sizes; and. w'nich presents F01" this situation it is usuaily other benefits and advantages as Will be apparent to those skilled in the art.
