ARA/0L0 J, Mg COLAN A TTOIZNEY United States Patent 3,300,120 CONTAINER Arnold J. McColgan, Pointe Claire, Quebec, Canada, as-
signor to W.'Ralston & Co. (Canada) Ltd., Montreal, Quebec, Canada, a corporation of Canada Filed Apr. 2, 1965, Ser. No. 445,136 2 Claims. (Cl. 229-55) This invention relates to a container and in particular a container made of a thermoplastic material.
In containers of this type, it is desirable to hang the container on a nail or peg, in order to properly display the same. This is particularly true when the container is made of a transparent thermoplastic material, such as polyethylene resin, polypropylene resin or other materials of similar type.
When a container is made of such thermoplastic material, and an opening is placed within the container to hang the same upon a nail or peg, the shear strength of the material of which the container is composed is generally not suflicient to support the same. Thus, a container made conventionally will tear if placed upon such a support.
In the container of this invention, the structure surrounding the opening therewithin is so made that a reinforced area is produced adjacent the opening which is of sufiicient strength to resist the shear produced by the hanging of the'bag. Also, the reinforcement means are integral with the bag so that the entire bag can be manufactured in one operation.
In an alternative modification of this invention, openings and reinforcing structures are produced at the top and bottom of the container so that the container may be hung either in normal or in inverted position.
The foregoing constitutes a brief description of the instant invention and the objects and advantages thereof.
Other objects and advantages of this invention will become apparent by a reading of this specification.
The invention will be further described by reference to the accompanying drawings which represent the best modes known to the inventor of carrying out his invention.
In this connection, however, the reader is cautioned to note that the specific forms of this invention as set forth in this specification, are for illustrative purposes and purposes for example only. Various changes and modifications could obviously be made within the spirit and scope of this invention.
FIGURE 1 is a perspective view of one form of a container made in accordance with this invention with the container hung in position upon a projecting member.
FIGURE 2 is a side view of the form of container shown in FIGURE 1 before the sealably connected portions thereof have been sealed to one another.
FIGURE 3 is a cross sectional view of acontainer similar to that shown in FIGURE 2 but with the scalable portions sealably connected to one another.
FIGURE 4 is a perspective view of the tubular material of which the body portion of the container of this invention is composed.
FIGURE 5 is a diagrammatic side view of an alternative form of the container of this invention prior to sealing the sealable portions thereof.
FIGURE 6 is a perspectivie view, partly in section, of the alternative form of the container of this invention.
Now referring to principal form of this invention as shown in FIGS. l-3, the container 11 of this invention ICC is made of a tubular thermoplastic material (preferably polyethylene resin or polypropylene resin). Container 11 is formed with a hollow body 12 having a front face 13 and a rear face 14. A transversely extending top portion 15 extends across body 12 and a transversely extending bottom portion 16 also extends across body 12. Along portion 16 front face 13 and rear face 14 are heat-sealed to one another. Along top portion 15, front face 13 and rear face 14 are intervened by inturned doubled portion 17. Portion 17 and faces 13 and 14 are heat sealed to one another along top portion 15.
Top portion 15 is also provided with an opening 18 approximately centrally located therewithin. Opening 18 is used to hang container 11 by means of a peg or nail 19 (FIG. 1).
In the alternative structure shown in FIGS. 5 and 6 container 11a is formed with a body 12a, having a front face 13a and a rear face 14a. A transverse extending top portion 15a and a transverse extending bottom portion 16a are also provided upon body 1211. A firstinturned doubled portion 17a intervenes front face 13a and rear face 14a along portion 15a and a second doubled inturned portion 18a intervenes front face 13a and rear face 14a along portion 16a. Front face 13a, rear face 14a and first intervening portion 17a are heat sealed to one another along portion 15a, while front face 13a, rear face 14a and second intervening portion 18a are heat sealed to one another along portion 16a. Between portion 16a and 15a front face 13a and rear face 14a are joined to one another laterally but are spaced from one another at points intermediate the sides.
A first opening 19a is provided within portion 15a and a second opening 20a is provided within portion 16a.
With the foregoing specific description, the operation of this invention may now be explained.
Turning first to the principal form of this invention as set forth in FIGS. 1-3, the container 11 is hung upon a peg 19 as shown in FIG. 1, peg 19 passing through opening 18. The strength of portion 15 is such that the shear produced by the weight of the bag will not cause a tearing of the material about opening 18.
In the alternative form of this invention shown in FIGS. 5 and 6, the bag may be hung upon peg 19, either through opening 19a or through opening 20a.
The foregoing sets forth the manner in which the objects of this invention are achieved.
What is claimed is:
1. An integral container of thermoplastic material comprising a tubular hollow body having a front face and a rear face therewithin, a transversely extending top portion and a transversely extending heat sealed closed bottom portion upon said body, an inturned doubled portion within said top portion intervening said front face and said rear face, said front face, rear face and intervening doubled portion being heat sealably connected to one another, said heat sealably connected portion provided with an opening therewithin, so that said container may be hung upon a nail or peg and subjected to a shearing force without tearing the portion adjacent said opening.
2. An integral container of thermoplastic material comprising a tubular hollow body having a front face and a rear face, a transversely extending top portion and a transversely extending bottom portion upon said body, a first inturned transverse doubled portion within said top portion intervening said front face and said rear face, a second inturned doubled portion within said bot- 3,300,120 3 4 tom portion intervening said front face and said rear 7 References Cited bythe Examiner face, said front face, rear face and intervening doubled UNITED STATES PATENTS portion within each of the respective portions of said container being heat sealably connected to one another, 2,690,253 9/1954 Francois 20645-33 each of said heat sealably connected portions being also 5 2,971,874 2/1961 0.3mm 22955 provided with an opening therewithin, so that said con- 31479O3 9/1964 Llpschutz et 229 55 tainer may be hung upon a nail or peg either in upright or upside-down position and subjected to a shearing force GEORGE RALSTON Primary Examiner Without tearing the portions adjacent each of said DAVID M.
