T. P. M GLYNN CONTAINER FORMING Filed May 8, 1964 Aug. 1, 1967 I! J" i H 4 3 17 :1
INVENTOR ATTORNEYS United States Patent 3,333,515 CONTAINER FORMING ThomasP. McGlynn, Short Hills, N.J:, assignorto Continental Can Company, Inc., New. York, N.Y., acorporation of New York Filed May 8, 1964, Ser. No. 366,035 4 Claims. (CI. 93-36) This invention-relates in general'to new and'useful improvements in the manufacture of containers, and more particularly to the formation of container blanks which are formed from coatedorlaminated material.
This invention particularly relates-to the manufacture of paper cups which are intended for use as hot drink cups and which are insulated by the application of a plastic foam to the paper. In the past, cups have been formed'of a plastic foam-paper laminate. However, the side seams of such cups have been defective in that the plastic foam does not sufliciently securely bond to the paper. On the other hand, when the'required paper-to paper bond is obtained, it is necessary to remove the plastic foam from one edge of the cup blank. This is a wasteful operation both as to time and material.
In view of the foregoing, it is the primary object of this invention to provide a novel method of forming container blanks from-coated or laminated web material wherein an edge portion of the web material is left uncovered and the container-blanks are so formed from the web material wherein the uncovered paper web forms one end'of the container blank and thereby permitsthe formation of a lapped paper to paper seam when a container body is formed from the blank It will be readily apparent that the method set forth in the above object is-a-highly desirable one. However, it will be apparent that it would be more desirable to have the web material of a greater width and a plurality of With the'above and other objects in. view that will. hereinafter appear, the nature of the invention will be.
more-clearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawing.
In the drawing:
FIGURE 1 is a plan view of alaminatedweb in .accordance with this invention with a plurality of arcuate container blanks outlined thereon.
FIGURE 2 is an end view of the laminated web of FIGURE 2 and shows the specific cross section thereof- FIGURE 3 is a' plan view of one of the blanks after from the blank of FIGURE 3.
' partof this invention. The foamed plastic web 12 may container blanks formed at onetime. Accordingly, itis another object of this invention to form container blanks in pairs from a coated paper web wherein the covering on the paper is of a lesserwidth than the paper web leaving narrow edge portions alongopposite sides of the paper web which are uncovered, andthe container blanks are formed in pairs in endtoend relation extending entirely across the covered web so that each container blank of a pair of container blanks is provided with one edge or end thereof which is free of the covering material.
It has been pointed out above that this invention particularly relates to the manufacture of cups. The average cup is of a tapered configuration so that the cups may be readily internested for shipment, storage and dispensing. As a result, the blank for forming the cup body is of an arcuate configuration so that when it is wrapped into the desired configuration, it will have a generally conical shape. Due to the curvature of such blanks, unless the blanks are properly cut from web material, there will be undue loss of the Web material. It is, therefore, another object of this invention to form arcuate blanks for cup bodies and like tapered container bodies from a continuous web with a minimum waste material, the body blanks being formed in pairs with the two body blanks of each pair being reversely arranged so as to be of a generally S-shape arrangement and with the remote ends of the blanks of each pair being parallel so that a pair of blanks will extend entirely across a web from which the blanks are formed.
A further object of this invention is to provide a novel method of forming arcuate blanks for tapered container bodies from a paper-plastic foam laminate in a manner wherein there is a minimum waste of material and each resultant blank is so constructed whereby a paper-topaper seam may be provided.
be formed of any suitable plastic which may be. readily foamed to provide insulating qualities and which is COrn-. patible with food products or other products'to be stored within a container to be formed from the. web 10. Itis to be noted from FIGURES l and.2 that the foamed plastic web 12 is of a lesser width than the paper web 11; It is also to be noted that the foamed plastic web 12 is centered with respect to the paper web 11" so that the laminated web 10 is provided with margins .13 and 14 of paper only. In the forming of container body blanks from the laminated web 10, it will be'seen that the margins 13 and 14 are advantageously utilized.
Reference is now made to FIGURE 3 wherein there is illustrated a container body blank, such as a blank for forming a cup, which is generally referred to by the numeral 15 and which is particularly adapted for the formation of a tapered container body. The blank 15 is arcuate in outline and includes a pair of curved, concentric side edges 16 and 17 of which the side edge 17 is of a greater radius than the side edge 16. The blank 15 includes a pair of end edges 18 and 19 which are of straight line configuration and which are disposed in generally converging relation. The blank 15 is provided with an end portion 20 which is formed solely of paper and the remainder of the blank 15 is of a laminated construction in accordance with the construction of the Web from which the blank 15 is formed.
Referring once again to FIGURE 1, it will be seen that when two of the blanks 15 are disposed in end-toend relation with the edges 19 of the two blanks in abutting relation, the two blanks form a generally S-shaped pattern and the end edges 18 are in aparallel relation. By placing the pair of blanks 15 on the web 10 in a manner wherein the end edges 18 thereof are parallel to the edges of the web 10, and by making the web 10 ;of a Width equal to the spacing of the end edges 18, it will be seen that the end edges 18 of the pair of blanks 15 register with the side edges of the web 10. In this manner, a pair of blanks 15 may be formed from the laminated web 10 without any waste whatsoever at the ends of the pair of blanks 15.
It will also be apparent that the pairs of blanks 15 may be disposed in closely nesting relation so as to minimize the waste web between adjacent pairs of blanks 15.
of the web 10, the uncoated margins 13 and 14 ofthe paper web 11 automatically form the uncoated end portions 20 of the blanks 15. Therefore, there is no problem of obtaining the proper coverage of the paper web portion of each blank 15 with the foamed plastic.
It is to be noted that although the blanks 15 of each pair of blanks are disposed in reversely facing direction, the blanks of each pair of blanks are identical.
After the blanks 15 have been suitably cut from the Web 10 by means of any suitable die cutting apparatus, adhesive is applied to the paper web portion of each blank at one end thereof and the blank is shaped into a tubular form with the end portion 20 overlapping the opposite end of the associated blank and being suitably adhesively secured thereto by means of adhesive 21, as is clearly shown in FIGURES and 6. If desired, a oertain amount of the adhesive will be provided for disposition between the opposite ends of the foamed plastic web portion of the blank 15 so that in the resultant container body a seal between the opposed end edges of the foamed plastic web portion will be obtained. This adhesive is referred to by the numeral 22.
It will be readily apparent that after the cup or container body illustrated in FIGURE 5 has been formed, further operations may be performed thereon, as is necessary, to form a completed container in the normal manner. The illustrated cup body is generally referred to by the numeral 23.
It is to be understood that while this invention is primarily directed to the formation of container bodies from V a laminated web, the principals of the invention may apply equally as well to coated webs wherein the coat ing material is of a type wherein the desired side seam bond cannot be obtained. Furthermore, while the principals of this invention apply primarily to the formation of blanks intended for generally conical container bodies, it will be readily apparent that the broad principals of the invention will apply equally as well to blanks for forming cylindrical container bodies. Such blanks would be formed in pairs in opposed end to end relation so that the remote ends of a pair of blanks would have uncoated portions;
Although only a preferred embodiment of the invention has been specifically illustrated and described herein, it is to be understood that other modifications may be made therein within the spirit and scope of this invention, as defined by the appended claims.
