PLURAL WALLED CONTAINER Filed Jan. 7, 1959 United States Patent O 3058624 PLURAL WALLED CONTAINER Edward B. Westlake, Jr., 307 Lincoln Ave., Havertown, Pa. Filed Jan. 7, 1959, Ser. N0. 785,437 1 Claim. (C1. 222-107) This invention relates 'co a container for liquids and more particnlarly relates to a plural-walled container for storing special types o-f liquids.
Certain types of liquids, such as various acids, are required to be stored and transported in plural-walled coutainers in order to minimize the danger of accidents in their handling. A problern in the fabrication of such containers has been the difficulty of producing a satisfactory joint or connection between such a plural-walled coutainer and an access tube 01' spout, which is fluid-tight, and is simple and inexpensive to form.
The present invention provides such a fluid-tight leakproof joint between a double envelope of a container and an access tube or spout. The tube is formed with a flange which is located between the two walls of the envelope, and the flange and walls are subsequently fused by an indnction heating process.
-It is, accordingly, an object of the present invention to provide a novel method for sealing a pouring tube to a double-walled container.
Another object is to provide a novel container structure cornprising a double-walled envelope and an access tube fastened thereto in such a manner as to provide a fluidtight eonnection to both Walls.
Other objects and advantages reside in the construction of parts, the combination thereof, the method of manufacture and the mode of operation, as Will become more apparent frorn the following description.
In the drawings, FIGURE 1 is a perspective view, partly broken away, showing the double-walled container f the present invention, including an access tube attaehed thereto, positioned within an outer container for transportation and storage.
FIGURE 2 is an enlarged fragmentary sectional view, showing the structure of the double envelope and the aecess tnbe in assembled relation, and the heating elements in proper position for fusing the two together.
FIGURE 3 is a sectional view showing the doublewalled container and the access tube integral therewith after the fusing operation has taken p1ace.
Referring now to FIGURE 1 of the drawings, a doublewalled container .10 having an access tube 12 attached thereto is shown positioned within a carton 14, such as a corrugated carton. Both the container and the tube 12 may be made from sorne suitable plastic material resistant to corrosion caused by the fluid being stored, but capable of fusing under application -of an appropriate amount of heat energy. Polyethylene has been found acceptable to the trade for shipping sulphurie aeid.
The carton 14 is provided with end flaps 16 to enable the container 10 to be sealed within the carton for transportation and storage. A d-ouble-walled container 10 is commonly required in the storage of fluids which are inherently dangerons, such as sulphuric acid, and where safety considerations are of prime importance. Both the inner and outer Walls cf the container are fused together along the line 18, so that the only passage from the interior cf the container is provided by the tube 12.
ice
Due to the dangerous character of the fluid to be stored within the container, it is especially important that the connection between the tube and the two walls of the container be absolutely fluid-tight. One means 0f accomplishing this is to fuse the tube and the two walls cf the container together. The manner in which this is accomplished in the present invention is illustrated in FIG- URE 2.
The tube 12 is provided, at the end which engages the container, with a flange 20 which is positioned between the inner Wall 22 and the outer Wall 24 of the double envelope. This flange 20 is integral with the tube 12. The flange may be formed from a portion of the tube flared irito the flange. It will be seen that both walls 22 and 24 are provided with apertures to provide access to the interior of the container by the tube 12. The aperture 26 in the inner wall 22 is of the same size and configuration as the bore of the tube, while the aperture 28 in the outer wall 24 is cf the same size and configuraden as the -outside of the tube 12 t0 permit said tube to extend through the outer wall 24 of the container.
A pair of metallic heating elements 30 and 32 are positioned on opposite sides cf the inner and outer Walls 22 and 24. These elements are cf the same general size and shape as the flange 20 and are provided with apertures which correspond in size to the apertures in the Walls adjacent which the elements 30 and 32 are positioned.
An alternating magnetic field is then applied to the elements 30 and 32 by an induction coil or by any other well known manner to cause said elements to become heated to a high temperature sufl1cient to fuse the tnbe 12 and flange 20 to the inner and outer Walls 22 and 24. This results in the structure shown in FIGURE 3, in whieh the tube 12 is in efiect integral with the walls 22 and 24 of the container 10.
After the fusing process has been completed, the beating elements 30 and 32 are removed from the walls 22 and 24 and the container may be closed by fusing the walls together in a well known manner along a line, such as is shown at 18 in FIGURE 1. -It is thns seen that by a simple, inexpensive and eifective method, a novel leakproof Container of dou-ble-walled construction and having an access tnbe integral therewith has been formed. The outer end of the tube 12 is provided with a sealing plug 12a fused to the walls of the tube 12. Before pouring out contents of the envelope or bag, the end of the tube 12 is out to eliminate the plug to open the tnbe.
Although the preferred embodiment 015 the device has been described, it will be understood that within the purview of this invention various changes may be made in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
