K R A L C P R PACKING CUSHION Filed March 7, 1933 INVENTOR Ffzfymond F. Clark ATTRNEY Patented May 1, 1934 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to a packing cushion top of the fruit between the upper layer and the cover and held against the fruit under pressure, and there is a serious objection to any cushion which damages the top layer of fruit, more particularly since this is the exposed layer when the such as used in the packing of apples and other fruit for holding the fruit against movement in the container, while also applicable to the pack- 5 ing of furniture or other merchandise where it is desirable to protect a surface during shipment or handling and prevent it from becoming marred.
One object of the invention is to afford a packing cushion that will not injure or scratch the surface of the fruit or other article which it is designed to hold and protect.
Another purpose of the invention is to afford a packing cushion that can be manufactured at a minimum cost and which will not absorb moisture as readily or to the same extent as cushions of the conventional types.
An additional purpose of the invention is to provide a packing cushion that includes a filler of maximum volume and resiliency and which has a greater capacity for filling a given space and holding packed fruit against movement in baskets or'barrels than cushions heretofore employed for this purpose.
To these ends, the invention consists in the construction shown in the accompanying drawing, and which will be described hereinafter, the novel features being pointed out in the claims following the specification.
In the drawing:
Fig. 1 is a plan view of a packing cushion made in accordance with the invention, and
Fig. 2 is a sectional view on line 22 of Fig. 1.
Referring more particularly to the drawing, in which like reference characters refer to the same parts throughout the views, the structure in one embodiment comprises an envelope preferably of paper made in two parts including a main body portion 1, the ends of which are suitably lapped or folded over the filler, and a cover or top portion 2 that is pasted or otherwise secured to the overlapped ends of the body portion 1. The construction of the envelope is shown in Patent No. 1,251,964, and the present invention has to do with the character of the filling material inside the envelope and the way in which it cooperates therewith.
Heretofore such cushions have been made generally by utilizing wood excelsior or similar material as a filler. This has a number of objections, foremost among which is its tendency to scratch or mark the surface of a thin skinned piece of fruit against which it is contacting, or a highly finished surface of furniture.
These cushions are used largely in the packing of apples and other fruit, being positioned on basket or container is opened, and any such damage to the fruit neces able loss to the packer.
sarily results in consider- Another objection to the use of wood excelsior lies in its readiness to absorb moisture from fruit so that when a package is left in storage, the cushion becomes damp and causes a certain amount of decay of the fruit.
In the present invention, the filler 3 consists of loose paper particles,
preferably in the form of elongated narrow strips of shredded newspapers or other similar paper stock that is sufiiciently thin, light weight, and purpose. able resiliency which otherwise suitable for the Such a paper filler possesses considerdoes not decrease as the paper dries and ages, whereas where cushions are made with a wood excelsior filler, the resiliency of the cushion lessens as the wood excelsior dries, and thus its efliciency as a packing medium is reduced.
of the paper particles to break through the envelope or to scratch or otherwise injure the articles with which they come in contact, and it possesses little tendency to absorb moisture from fruit.
The invention is illustrated in connection with a circular cushion such as used for the packaging of apples in baskets or barrels, but may be applied to cushions of square or other conformation,
or to other shapes whe re used for packaging furniture and other articles, and it is intended that this application cover any modifications or departures coming within the intent of the improvement or the scope of the following claim.
A packing cushion comprising an envelope of readily yieldable paper which entirely surrounds and completely encloses a filler, said filler consisting of elongated narrow strips of shredded newspapers occupying the interior of the envelope and contacting at all portions of the inner surface of the latter.
