Filed April 9, 1941 METHOD OF MAKING TUBULAR CASINGS FOR SHIPPING CONTAINERS Patented Apr. ll, 1944 UNITED STATES PATENT OFFICE 'METHOD OF MAKING TUBULAR CASINGS FOR SHIPPING CONTAINERS George Kress, Green Bay, Wis. Application April 9, 1941, Serial No. 387,600
6 Claims.
This invention relates to a casing and container and a method of making the same.
An object of the invention is to provide a strong tubular container and a simple inexpensive method of making the same from corrugated material and liner sheets.
Another object is to provide a container of cor: rugated material equipped with inner and outer liner sheets, the sheets being of a different material than the corrugated material. Another object is to provide a tubular casing of corrugated material with liner sheets secured to the inside and outside surfaces of the casing, the liner sheets being tightly secured to the extending surface of each of the ribs of the corrugated material. Still another object is to provide in a casing of corrugated material equipped with liner sheets on the inside and outside thereof, an overlapping of the liner sheets with the opposite sides of each of the sheets secured together in overlapping relation and with the overlapping portions of the inner liner being disposed in a different portion of the casing than the overlapping portions of the outside liner. Yet another object of the invention is to provide a method for making a tubular casing wherein a substantially straight sheet of corrugated material has a liner secured to one side thereof and the corrugated sheet with the liner attached is thereafter formed into a tubular casing and a secondary liner applied to the other side of the corrugated sheet.
A further object of the invention is to make a container of corrugated material with the ribs of the corrugations extending longitudinally with respect to the body of the container and with inner and outer liners wrapped transversely around the body of, the container and secured thereto. Another object is to provide a closure member for the container, the member including a corrugated sheet equipped with a depending annular peripheral flange and to provide a band and peripheral flaps on the sheet to form the flange. Still another object is to provide a tubular casing of corrugated cardboard which is open at both ends and is equipped with closure members adapted to be removably attached to the open ends of the casing to cover the same.
Other objects and advantages will appear from the following specification and drawing in which- Figure 1 is a side elevational view of the container; Fig. 2 is a vertical sectional view of the container taken along the line 2-2 of Fig. 1; Fig. 3 is a vertical sectional view partly broken away of the tubular casing or body of the container mounted on a mandrel, the view being taken along the line 3-3 of Fig. 2; Fig. 4 is a transverse sectional view of the tubular casing mounted on a mandrel, the view being taken along the line 4-4 of Fig. 3; Fig. 5 is a fragmentary detail sectional view of the upper portion of the container and Fig. 6 is a fragmentary detail transverse sectional view showing the wall of the container.
In the construction of containers and the like from corrugated materials such as corrugated cardboard considerable difliculty has always been encountered in attempting to provide a curved or rounded wall of the corrugated material. Corrugated cardboard, in order to be effective and satisfactory for most purposes, should be provided with a liner of cardboard or similar material on both sides of the corrugated sheet. In preparing corrugated sheets of cardboard, the liners are usually secured to the sheet immediately after it is subjected to the corrugating rolls. The resulting product is a straight sheet of corrugated material with a cardboard liner on either side thereof. Such a product cannot be successfully used in making containers which are provided with rounded and curved surfaces since in order to bend the sheet to an arcuate form it is necessary to either crush the corrugations or release one or both of the liner sheets from the material.
Efforts to make tubular containers from corrugated cardboard by forming the corrugated sheet into a tubular casing before the liners are applied have been similarly unsuccessful. When the liners are attempted to be applied it is found that the ribs of the corrugations are not in alignment and it is difiicult, even impossible, to attach the liners to each of the ribs. Thus, if it were attempted to attach liners to such a tubular casing of corrugated material, the liners could not be brought into contact and engagement with the extending surfaces of each of the ribs without great difiiculty and the use of expensive equipment and operations.
In the present invention, a container of tubular or curved or arcuate form may be made of corrugated board and by following the simple steps set forth the corrugated material may be provided with liners which are tightly secured to each of the ribs on both sides of the corrugated material.
The general steps of the present invention include the providing of a substantially straight sheet of corrugated cardboard or the like, adhesively securing a liner sheet to one side of the corrugated sheet, forming the corrugated sheet with the liner attached into a tubular casing and applying a second liner to the other side of the corrugated sheet.
In the specific embodiment of the invention described herein, a container I is equipped with a tubular casing or body portion II and with upper and lower closure members or covers I2 and I3. The wall of the tubular casing as seen particularly in Fig. 6, includes a sheet 01 corrugated material I4 and an inner liner I5 and an outer liner IS. The liner I5 is adhesively secured to the corrugated sheet I4 at the extending surfaces I! of the ribs of the corrugated sheet. Similarly the liner I6 is adhesively secured to the outwardly extending surfaces I8 of the ribs of the corrugated sheet.
The corrugated sheet l4 may be made of cardboard or any other suitable material such, for example, as synthetic products such as those sold under the trade name Masonite but referred herein to corrugated board. I intend to include cardboard and other suitable materials which may be made into corrugated sheets.
The liners I5 and I6 are preferably made of sheets of hard surfaced cardboard and are normally lighter than the corrugated sheet. If desired, paper or other suitabl material can be used for the liner sheets.
In making the tubular casing or body portion ll of the container, a sheet of corrugated material I4 is secured to the liner I6. The corrugated sheet I 4 is preferably substantially straight and may be attached to th liner sheet by adhesive, the adhesive being applied to each of the extending surfaces I8 of the ribs of the corrugations or to the surface of the liner I6. The adhesive is permitted to dry to form a tight bond. The inner liner I5 is placed around a suitable mandrel 20, the mandrel being of a diameter equal to the desired inside diameter of the container. The liner I5 is somewhat wider than the corrugated sheet l4 and extends entirely around the mandrel I6 with the opposing sides of the liner l5 overlapping at 2|. The overlapping portion of the liner I5 is adhesively secured to the other side of the liner sheet. Adhesive may then be applied to the outside surface of the inner liner l5 and the corrugated sheet applied to the liner or to the inwardly extending surfaces I! of the ribs of the corruated sheet.
The corrugated sheet is wound around the mandrel in tubular form with the extending surfaces I'! of the sheet l4 being brought into engagement with the outside of the inner liner I5. The outer liner I6 is of a greater width than the corrugated sheet I4 so that when the sheet I4 is formed around the mandrel 20 the portion I9 of the outer liner I6 is adhesively secured to the opposing side of the liner. If desired, the overlapping portions of the inner and outer liners may be disposed on opposite sides of the tubular casing. When the adhesive has dried the tubular casing is complete and may be removed from the mandrel 20.
The closure members I2 and I3 are identical in construction and may be easily and readily made. In the making of the colsure member a cardboard strip 22 is formed into an endless band. A sheet of corrugated material 23 equipped with inner and outer liners 24 and 25 respectivel is placed across one of the open ends of the band. The sheet 23 is of such a size that the periphery thereof extend beyond th band by a distance substantiall equal to the depth of the band. The sheet 23 with the liners attached thereto may then be cut away at the portions 28, these portions preferably being of V-shape. The space v notches in the sheet 23 thus provide spaced peripheral flaps 21 in the sheet. The flaps 21 are turned downwardly along the outside of the band 22 and adhesively secured thereto. If it is desired to permanently attach on or both of the closure members to the tubular casing, the inside of the band 22 may be coated with a layer of adhesive and thereby attached to the outside of the casing.
In the tubular casting II, the ribs of the corrugations are disposed longitudinally with respect to the casing and the liners are wrapped transversely about the corrugated body portion with the ends of the liners disposed in overlapping relation. Preferably, the liner sheets as shown are wound around the corrugated body portion in a direction substantially normal to the axis thereof. With this construction, a maximum strength is provided by the ribs while the liners are tightly secured against removal from the corrugated sheet. By applying the outer liner to the corrugated sheet before it is formed into a tubular casing, a tight adhesive bond is formed by the ,liner and the extending surface of each of the ribs of the corrugation. When the corrugated sheet is thereafter bent the attachment of the ribs to the outer liner maintains the ribs in alignment with each other during the bending operation. Accordingly when the inner liner is to be adhesively secured to the corrugated sheet it may readily be brought into engagement with the inwardly extending surfaces of each of the ribs. 35
This feature is extremely important since, if the ribs are out of alignment by even a few thousands of an inch, a good adhesive bond will not be obtained with all of the ribs. Moreover, with this construction, the outer liner is very tightly secured to the corrugated sheet and any weakness in the adhesive bond which should appear is more likely to be present in the inner liner where it is least important.
The tubular casing II as shown, is cylindrical in shape but may if desired be of oval, elliptical or other shape. By referring herein to the corrugated board as being straight when the outer liner is attached thereto I mean that a line drawn through the extending surfaces on one side of each of the ribs of the corrugations is substantially straight.
While there are shown and described certain embodiments of the invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is intended to claim all novelty inherent in the invention as broadly as permissible, in view of the prior art.
