SHOCK RESISTANT CONTAINER John Kearsley M. Harrison, Gainesville, Va.
Application June 24, 1947, Serial No. 756,662
8 Claims This invention relates to containers and particularly to nonmetallic containers of the type used for the packaging of liquids such as oils or foodstuff.
In the design of containers made of plastic, paper or other nonmetallic material the principal problems presented are the maintenance of an adequate cost margin over metal containers together with the attainment of such objectives as mechanical strength, adequate resistance against leakage of liquid from the container, adequate resistance against leakage of moisture into the container, and ease of access to the container contents.
Toward the attainment of the foregoing objectives much effort has been expended and many forms of paper containers are now available in competition with metal containers of like capacity. With the advent of new liquid-proof plastic materials, the problem of leakage through the walls of nonmetallic containers has been to a large extent solved. However, the problem of mechanical strength has not been heretofore solved in any inexpensive manner which is consistent with commercial requirements regarding resistance to leakage at the seams between the end closures and the remainder of the container.
It is therefore an object of this invention to provide a nonmetallic container for the Shipment and storage of liquid materials which is characterized by a simple and inexpensive type of construction which is very resistant to mechanical shock and which wholly prevents outleakage of the contents of the container and inleakage to those contents while affording a closure which may be easily broken when desired to gain access to the contents of the container.
It is contemplated, according to this invention, to provide a nonmetallic container having an end structure characterized by a flexible portion and a rigid portion ccacting to provide adequate seals and high resistance to rupture-incident to rough handling or other mechanical strain.
Other objects and advantages of the invention will be apparent upon consideration of the following detailed description of a preferred embodiment thereof in conjunction with the annexed drawings wherein:
Figure 1 is a view in vertical section of one end of a cylindrical container constructed in accord ance with the teachings of the present invention; and
Figure 2 is a view partially in vertical section and partially in elevation illustrating one of the steps in an assembly of a container of the type shown in Figure 1.
Now referring to Figure l in greater detail, the container consists of a cylindrical body portion III of which only the upper portion is shown in the drawing. It is contemplated that the lower or unshown end of the container will be provided With a closure either of the type shown in conjunction with the top closure in Figure l, or of some other type known to the art.
The upper closure for the body portion I 8, which is shown in Figure 1, is comprised of a flexible disc I I of laminated parchment, cellophane, or the like having an integral annular flange I2 extending toward the end of the container, a rigid closure disc I3 and a rigid cover disc [4.
The flexible closure disc II has an over-all area in excess of the cross sectional area of the container body at the plane arb indicated in the drawing, so that the disc I'! may flex in response to pressure differences thereacross. The disc I! is inserted in the cylindrical body IS in the manner shown in Figure 2. An annular zone It adjacent the end of the cylindrical body I0 is coated with a suitable adhesive and then the disc I I is forced through a dye l5 by a plunger I6 and is pushed to the position indicated in Figure 1. The plunger deforms the marginal portions of the disc II to form the flange l2 and likewise displaces the adhesive to form an annular sealing fillet at Ii, see Figure 1. It should be noted that the end of the plunger I6 is convex so that the portion of the disc II which extends across the container body will have an area slightly in excess of the cross sectional area of the body.
From the foregoing it can be seen that the disc I l is held in position by the adhesive and is put into position as the first step in effecting the endclosure. After the disc II has been placed in position a rigid closure disc I3 is inserted and this disc is wedged in overlying relation to the flange I2 of the disc II. The disc I3 is slightly frusto conical and is inserted with its face of minimum diameter extending inwardly toward the center of the container. As it is pushed into place its margin exerts a wedging action on the flange i2 and serves to supplement the adhesive in holding that flange against the wall of the container. After the disc I3 is in position, the end of the container is spun over at I8 to hold the disc I3 in position. In View of the fact that forcing the disc I4 in position might create sufficient air pressure to rupture the disc II, disc I3 is provided with a vent aperture at l9 so that air trapped between the discs I l and I3 during the insertion of the disc I 3 is permitted to escape.
After the disc I3 has been placed in position and the spun over portions l8 have been formed, a waterproof cover disc I4 is wedged in position overlying the disc I3 and is held marginally by the spun over portion 58. The disc I4 is impregnated with a waterproofing material and forms with the spun over portions I 8 a very tight flt at annular zone 20. This fit, together with the waterproofing character of the disc 14, prevents contamination of the contents of the container by in-leaking water. Out-leakage of the contents of the container is prevented by the disc I! and the sealing fillet [7. If the container is dropped or otherwise subjected to rough handling, the gas trapped in the space between the flexible disc H and the rigid disc I3 is compressed momentarily to act as a resilient cushion preventing permanent displacement of the rigid parts of the end closure and protecting the container against shock damage.
l/Vhile the invention has been described with respect to but a single embodiment thereof, it is apparent that various changes and modifications of the construction are possible within the scope of the invention as defined by the appended claims.
