Description

June 11, 1957 D. G. MAGILL DUAL PURPOSE PULL STRIP Filed May 5, 1955 ATTORNEYS United States Patent DUAL PURPOSE PULL STRIP Donald G. Magill, Great Neck, N. Y., assignor to American Can Company, New York, N. Y., a corporation of New Jersey Application May 5, 1955, Serial No. 506,259
7 Claims. (Cl. 22951) The present invention relates to fibre containers havingpull strips for opening them and has particular reference to such a strip which also serves as a means for protecting an exposed fibrous portion or edge of the con tainer.
In packaging certain products in fibre containers having interiorly exposed raw edges, such as score lines and lapped side seam edges, considerable difficfilty is often I experienced in preventing ingredientsof the product from seeping through these raw edges into the fibre material of which the containers are made. Volatile, oily, greasy or liquid ingredients if permitted to seep into the fibre material weakens the container and often causes its failure as a container. Such containers also are often difiicuit to open without the aid of a tool such as a knife or the like to cut through the fibre material.
An object of the instant invention is the provision in a fibre container for products of the above suggested nature, of a pull strip which serves a dual purpose of protecting a raw exposed edge in the container and also serves as a means for easily opening the container to gain access to its contents.
Another object is the provision of such a dual purpose pull strip which may be readily and economically applied to a composite container, i. e. a container having a fibre body and metal end closures.
Another object is the provision of such a dual purpose pull strip which is inexpensive and which may be economically and easily attached to the containers during their manufacture without interfering with subsequent manufacturing operations.
Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.
Referring to the drawings:
Figure 1 is a perspective view of a composite fibremetal container embodying the instant invention, parts being broken away;
Figs. 2 and 3 are enlarged sectional views respectively taken substantially along planes indicated by the lines 22 and 3 -3 in Fig. 1, parts being broken away;
Fig. 4 is a perspective view similar to Fig. 1 and showing a modified form of the invention; 7
Figs. 5 and 6 are enlarged sectional views respectively taken substantially along planes indicated by the lines 55 and 6-6 in Fig. 4, parts being broken away;

Fig. 8 is a perspective view of the upper end of a container similar to that shown in Fig. 1 and illustrating a further modified form of the invention;
Patented June 11, 1957 Fig. 9 is an enlarged sectional view as taken substantially along a plane indicated by the lines 9-9 in Fig. 8; and
Fig. 10 is a fragmentary sectional view taken substantially along'the line 10-10 in Fig. 9.
As a preferred or exemplary embodiment of the instant invention Figs. 1, 2 and 3 of the drawings illustrate a composite container for products such as biscuit dough, pie dough, frozen citrus concentrates and the like products. Such a composite container preferably comprises a fibre material body 21 and sheet metal top and bottom closure members 22 made from tin plate, black iron or the like sheet material and secured to the body in suitable end seams 23.
The fibre body 21 preferably is made from a one-piece fiat blank formed into cylindrical shape to produce a tubular cylindrical body having opposing marginal edge or lap portions 24, 25 overlapped and secured together by adhesive 26 to produce a lap side seam 27 which holds the body together. The inner and outer surfaces of the body 21 preferably'are protected by a gasproof, moistureproof, waterproof and greaseproof coating material such as a metal foil (tin or aluminum), a microcrystalline wax, plastics as Saran (polyvinylidine chloride), Mylar (oriented polyester resin) or other suitable materials. However the inner and outer laps or marginal edge portions 24, 25 of the side seam 27 terminate in raw edges 29 (Figs. 2 and 3).
In order to protect the raw edge 29 of the inner lap 24 against seepage thereinto of the container contents, this edge is covered or enclosed in a narrow strip or tape 31 of high tensile strength, such for example as oil and moisture resistant regenerated cellulose (cellophane) material. The tape 31 is adhesively secured to the raw edge 29 and to the immediately adjacent marginal portions thereof on both sides of the fibre material as best shown in Fig. 3. The tape 31 extends the full length of the edge 29 on the inner lap 24. Adjacent the top end of the container the tape 31 is bent outwardly back on itself and extends transversely of the side seam 27 between the inner and outer laps 24, 25, and terminating beyond the seam and on the outside of the container, in a tail or pull tab 33 where it is clear of the seam during the formation of the seam in the manufacture of the container.
While the container is in use as a holder of a product, the tape 31 shields and thus protects the inner raw edge 29 of the side seam 27. When it is desired to open the container to release the product a pull on the tab 33 in a direction toward and thence along the side seam tears the seam across to the inner raw edge 29 and then tears the seam longitudinally along. the inner raw edge for the full length of the container body thus opening the body. During this scam tearing action the tape 31 is also torn off the inner raw edge 29 but this is intended since the protection of the raw edge is no longer needed. Thus the tape 31 serves the dual purpose of protecting the inner raw edge of the side seam 27 while required and also acts as a means of opening the container to gain access to its contents.
. As a modified form of the invention Figs. 4, 5, 6 and 7 illustrate a strip or tape 35 similar to the tape 31 of the preferred form of the invention, with the tape 35 applied t 3 I. notch which is so located as to be incorporated in the end seam 23 of the container so as to avoid direct communication therethrough between the interior and the x er o -Mme ntaine Ihebott m fthe o h-P e erably is located so as; to; provide for ,the; incorporation of the tape 35 in the end seam 23 in such a manner that it .canbe readilypulledout, :ht i r r i Hence while the filledcontainen {is in use the-tapen35 overlapping, the side seam;27;protectsthe1innen raw edge 29 ;of the seam against; permeation {by the contents of the container-and whenthecontainerlis tohe opened, a puli on .the tab ,37 withdraws the tape fljom the enchseam 23 and tears thecontainer body longitudinally. along the side e m pe the b dy to expose itsrec t n Thus as, inthe preferred form, ofithe initentiongrthe -.tape 35 er es-th am du -purp se.
In another modified form of the invention as illustrated in P125118. fiend 1.0, a. tape tlt mi to th p of the preferred form, is utilized-to. coverand protect an annular raw edged score line 42; which preferably extends entirely around thebody21 adjacent its :upper; end- .The score li ne:42 is formed inthe inside'surface of the. con tainer body. The tape 41 overlaps and extends along the score. line and, is adhesively' secured to the inner surface of the body, At the side seam, 27 one .end of-the tape covers the aforesaidraw edge 29 of the inner. lap24 so as to'entirelycover the score line 42 at this edge. The other or opposite end of the tape 41extends it between the innerand outer laps 24, 25 of the-seam as shown in Figs..9 and 10 and projects andterminatesoutsidethe body in a pull tab 43.
Hence while the container is in use prior to opening, the tape 41 overlapping and shielding the score line 42 protects theraw edges of the score line against ingress of the container contentsand when the. container is to be opened, apull on the tab 43 readily tears the body 21 transversely acrossthesideseam 27 and circumferentially along the score line 42 to completely sever the top end of the container from the body 21 so as to facilitate access to the contents of the container. Thus as in the preferred form of the invention the tape41 serves the dual purpose of protecting the described raw edges of the body and score line and also serving to open the body by a severing operation. 7
.It is thought that the invention and many of its attendant ,advantages will be understood. from the, foregoing description, and it will be apparent thatwarious changes maybe madein the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or'sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.
