Zen 214 United States Patent 2,828,061 END CLOSURE non A MULTI-SIDED CARTON Hans Zerlin, Dusseldorf, Germany, assignor to Jagenberg- Werke Akt.-Ges., Dusseldorf, Germany Application March 29, 1954, Serial No. 419,441 Claims priority, application Germany May 26, 1953 2 Claims. (Cl. 229-43) The present invention relates to the art of containers.
More particularly, this invention relates to an oil tight container of paper, cardboard or the like carton forming material.
Still more particularly, this invention relates to a polygonal container made of suitable carton forming material that is to receive oil or similarly thinly fluent material, and which container is provided with inserted end closures at one or both ends.
Containers for thinly fluent materials are already known, which are usually manufactured by erecting a generally rectangular blank into a tubular body form with the inner side of the body provided with a moisture proof coating and with the upper and/ or lower opening of the container body closed by a closure member preferably made of the same material as the container body. These end closure members correspond in shape to the cross sectional form of the container and are provided at their edges with flanges which will be erected while the closure member is inserted into the open end of the container body to thereby bear against the inner surface of the body at its edges and to be folded down about the external edges of the body so as to enclose the edges in U-shaped formation and to be subsequently compressed to a tight closure about the edges.
In order to provide a liquid or oil tight container of this material, corner staying or sealing presents particular diliiculties. For this reason the closure member blanks are formed so that the flanges along the opposite sides thereof are interconnected at their corners with large and substantially triangular shaped sections so that when the flanges are set ,up these sections connect adjacent flanges of the closure members when the closure is inserted into the carton. Although this arrangement will to a certain extent provide a closed edge at the flanges and therefore a closure that is sufficiently tight for certain goods, it will result in a multiple overlapping of the relatively heavy blank material in the region of the corners of the container. This multiple overlapping tends to form channels or tunnels which will not be closed by any binding agent coated on the inner side of the closure member, since the layer of the binding agent is too thin with respect to the thickness of the material of the closure member blank; Additionally the tunnels will further provide escape channels for seepage and which tunnels due to the thickness of the blank material cannot be closed in the compressing operation applied to the closure member in the securing thereof to the container body.
The present invention, therefore, has for an' object to provide a container that is oil tight, that is, leakproof and which eliminates the aforementioned difliculties.
The invention consists in forming the closure member from a blank which is provided with flange forming portions for association internally and externally of the container body and which flange forming portions are formed by cutting out the blank at the corners in com- 2,828,061 Patented Mar. 25, 195% 'ice bination with a leaf of metal foil which only partly or totally covers the inner corner recesses of the closure member blank so that in setting up the flanges and inserting the closure member the portions of the leaf of foil that cover or extend between the corners of adjacent inner flanges on the blank apply themselves around the edges formed by the erected inner flanges. In connectionwith the invention, the corner recesses or cut outs at the corners of the blank are inwardly limited by the prolongations of the embossed or creased lines or grooves which define the plane of the closure member and the leaf of foil is associated with that side of the closure member facing the interior of the container.
In accordance with the invention, the closure member blank with the corner recesses assumes the function of stiffening the cross sections of the container and for covering and protecting the leaf of foil, while the leaf of foil effects a perfect 'seal or tightness at the internal corners of the container.
Utilizing the arrangement of the invention, overlappings of relatively stiff or thick blank materials at the corners of the c onta'iner are eliminated and the thinness of the leaf of foil ensures an effective sealing of the internal corners and encompasses the edges formed by two adjacent inner flanges. Due to the insignificant thickness resulting from any overlapping portions of the foilleaf any tunnels or channels appearing therein will be entirely filled up by a layer of binding material or agent that has been applied to the lower or inner surface ofthe leaf of foil. t j Furthermore, the provision of the foil leaf in association with a closure member blank having completely cut out corners .will reduce the pressure required in securing the closure to the containenparticularly at the corners thereof, so that the closure can. be securely bonded to the container body without any risk of deforming the container material and thus eliminating any necessity to utilize the highpressing power previously used when the closure blank itself was provided with covering portions at the corners of the flanges or flaps and which cover portions had to be folded and refolded to fit within the container and thus provided the multiple overlappings of blank materials.
, A furtheradvantage of a container in accordance with the invention. consists in the loose superimposition of the surfaces, corresponding to the cross sectional shape of the opening of the container body, of the blank part with the corner recesses on the one hand and of the leaf of foil on the other hand; that is, the foil and container closure blank are not connected together in the major area of the closure. This process presents the advantage, in contradistinction to providing laminated foil materials, that the slight tensile strength of the leaf of foil can follow, free from tension or strain, any deformation of the blank part during insertion of the closure member without beingsubjected to any particular strain that might damage the foil.
t In addition, in accordance with the invention, the blank portions that form the closure member and the leaf of foil are both provided on their sides directed toward the to each other by the inserting and compressing tools will and 8 and introduction of the thus set up closure consisting of combined blank 2 and foil 3 into the container body 1, as shown in Figure 4, the sections or 10' of the leaf of foil that cover the corner recesses 9 of the closure blank 2 will take the form of outwardly buckled web portions 10''. In the subsequent inserting movement these web portions will embrace the edges of the set up closure blank between the internal side of the container body 1 and the flanges 7 of the closure member 2 and flanges 7 of the foil leaf. The combined closure member 2 and foil 3 inserted into the container body down 'to the score line 6 will be completed by folding down flanges 8 around the edges of the container body 1, as shown in Figure 5, and the foil flanges 7' that underlie the flanges 8 are adhesively secured thereto under the action of heat and pressure established by the conventional reciprocable sealing tools. In this operation layer 12 becomes plastic and connects the flanges 7 and 8 of the blank 2 with the flange forming portion of the leaf of foil 3 and the coating layer 11. The coating =1ayer 11 is also secured to the coating layer 13 on the interior of the container body and to the exterior of the container body in that portion crossing the top edge of the container and underlying the flange 8. As previously described, since the flanges 8 of the container closure blank are longer than flanges 7 the adjacent edges of flanges 8 will meet at the exterior corners of the container to form a tight external corner closure. Further, the flanges 7 will provide rigidity in the transverse direction on the interior of the container, and the web portions 10" will securely seal the interior corners of the container since the thinness of the leaf of foil will perrnit adequate compressing of foil into the corners with any channels or tunnels formed therein being filled and sealed by the adhesive layer 11 which becomes soft during the process of sealing.
It is to be pointed out that this invention comprehends the superimposition of a closure blank having free flange forming portions extending from each side over a foil element that at least extends between adjacent side edges of the adjacent flange forming portions and inserting the superimposed blank and foil element or elements into the open end of the container to fold up the flange forming portions and wedge or compress the foil into the inner corners of the container to seal these inner corners.
It is to be further understood that this invention is not to be limited to an arrangement in which a complete leaf of foil underlies the entire closure blank since an effective corner seal will result from the provision of a leaf of foil underlying the corner recesses of the blank part, as at 9, and at least extending partially along the under surfaces of blank forming portions 7 and 8.
What is claimed is:
1. In a leakproof container of paper, cardboard or like canton forming material, a body including side walls and a rim, said side walls defining a multi-cornered construction, a closure for at least one end of the body including a main closure panel having free flanges extending therefrom, said flanges corresponding in number and transverse extent to the number and transverse extent of the side walls of the body and being substantially at right angles to the main panel and extending away therefrom a distance at least sutficient to be opposed to the inner surfaces of the side walls so that the main panel lies inwardly of the rim of the body, a lining sheet arranged interiorly of the main closure panel and including uninterrupted perimetrical portions secured to the flanges and the adjacent inner surfaces of the side walls, and said perimetrical portions including web portions in the interior corners of the body embracing only the adjacent inner edges of the flanges at each inner corner and extending axially of the container only between the corners formed by adjacent inner flanges and the respective interior corners of the container.
2. A leakproof container as claimed in claim 1 in which said lining sheet is a foil lining sheet and includes a main body portion underlying the main panel of the closure and free of positive connection thereto.
