United States Patent C) CONTAINER 1 Application August 24, 1955; Serial No. 530,294 11 Claims. (Cl. 229-14 This inventionrelates to'a container of the type commonly manufactured from paperboard and covered with sheet-1mater1al, for. example, paper. The paper coveringis intendedrto improvethe external appearance of the-boxand usually hasa-glossy, surface, and'isin'many cases decorated with an ornamental-design; Moreparticularly, itis concerned witha double' walled container'of the typedescribed, wherein a portion-ofethe covering material is utilized to hold the double walls of 'the contain'er'in a fixed relationship.-

Certain double walled :containers of I the: typev described above are commonly used, for example, for the packags 1ng.:of cosmetics, and are typically formed in :three'rparts,

and .the cover. The box is a-baseisectioncomprising a bottom and side-walls, and-is openat thetop; Theiwalls of the base-rare usually, but--not necessarily,- 'rath'emlowas compared tortheroverallt height of-thercontainer. The neck is a sectioncomprising sidewalls, :andfit telescopeswithin the base and within the cover. The cover.is'si1ni1ar'- tothe base-in construction-except that its walls "are'usu'all y', but not necessarily,-.higher than the walls 'ofZ'the-base'. The neck forms the. inner wall of the double-walledvcom:

tainerand the walls .of the base and cover'together form' the outer wall.

While the container described herei ..=isirectangular, having four walls, it should be- 1 quite apparent :that' 'the invention is equally applicable 1o.containers- 0f circular orother configurations.

Whencovering a container .of the=type described-with:

paper or other.sheet-materiahtthe procedure 'cornmonlyz' used is. tocover the sections of the-container separatel-yz For-example,--the base orcover*-is placed on --ar'1- adhe-'- sively coated side of a :sheet of =paper-and-the #sheet-"of paper is -then-tfolded up oventhe sides of the base or cover. The neck is covered :by a strip of sheet: material which .is adhesive Ion its inside;

The base is :thenadhe-v' sively 'coated'on theinner side-of-the wall,:..or the neck: is -adhesively coated onthe outside,--the base-wand neck are then assembled and the adhesivecoatingsetsto keep them'together as a permanent-siftproofunit.-

When assemblin g the cover on such 1 a container; it I is r necessary that thecover slide-'readily.over the outside 0f the neck. The box or base, on the other hand, beingpermanently assembled with the neck,---is' constructed with a much smaller clearanceso that theneckfits witliin it-rrio're tightly than :within theouver.-

It is desirablethat -the finished box have no edge or projec-tiomat the par-tingi line -=between the cover and the' 'base. In' other Words,-

the "outside surfaces of the =cover 'and base Should' be aligned. Since the cover must be made withgreater clear ance-for'the -r1eck and the base;'it has'beerr'a commonpractice to make the base of thicker material than the' cover and :neck zso that the outer surface 'ofthe base 'will be in line :with the outersurface of the cover after' the box is assembled. The =gre'aternthickness-of the base-material is'not necessary from the standpoint of strength buf only fon'thesake of app'earancera An object of the present invention is to providea-com tainer of the type described, in which-the paper covering also serves to holdthe base and neck-sections togetheras a siftproof unit.

Another object is to provide a container ofthe type described, which is improved from" the standpoint-of= economy of-material.

Another object is to provide -a-me thodof manufac'--- turinga containerof the type described, which-method is. improved both fromthe standpoint of economy: ofmaterial and fro the standpoint of the number of-opera-" tions required to completethe container.

The foregoing objects are attained,inthepreferredembodiment described 'herein, .by assemblinguncovered conventional neck and'ba'se structures of the type-dc scribed so that the neckis telescopedonly part way. into the base. A covering .of-sheet material suchas paper is th'en"adhesive1y,attached to the partly: assembled neck and base, using. the procedures. common in the art for covering the base alone. Thisleaves a portion-of thesheetmaterial :just'abovethe edge of the base v v hich=is not attached 'to either the base or the neck. The neck isthen moved all the way into completetelescoping rela--' tion with the-base, the unattached'portion of the covering? materialdbeingthereby drawn within the base to-forna; a;- foldbetweenthe walls'of the-neck and -the=base.-- This-= fold provides increased thickness of the ledgeat the upper endlofthebase'wall so that the outer surfaces of the-- covera'ndbase are aligned without the use of thickerhiaterial for the base, as in-the prior art structures, ;wit-h res'u'lt'ant'economy. The coveringof she'et material com-- pletely seals the baseto the neck, providing: asiftproof unit.

Figs: 1- 8 Referring now specifically'to" the drawing, there are shown 'in"Fig. l, the parts "required 'to 'producethe' lco'fnple'tecontainer"ofFigs."5 and '8." These 'part's"include*a the" neck-2 and-anothersheet 5 of-coveringmaterial;

which in "the fir'iishe'd container will enclose -the' cover While tlie 'cover ing material is typically" paper, it may alternatively be cloth, or other suitable sheet material? Fig. 8 is a"pers'pective view showing -thecompleted 1 The neck 2 is illustrated as being of the type known in the trade as a rim neck, comprising four walls formed from a single piece of paperboard by scoring and folding, and joined at one corner by means of an adhesive paper strip or by a peeled lap joint.

The invention is also applicable to other types of neck structures, including a full neck having a bottom in addition to the four walls.

Thefirst step in the manufacture of the container is to move the neck 2 into a position where it is partly telescoped within the base l, as shown in Fig. 2. It should be emphasized that the neck 2 is not moved against the bottom of the base 1 at this time, but that a substantial space is left between the bottom of the neck 2 and the base 1. Since there is substantial lateral clearance between the neck 2 and base 1, the parts must be held in these positions by external means, for example, by means of blocks between the lower edge of the neck 2 and the inside bottom of the base 1.

The cover sheet 4 is then folded over the assembled base 1 and neck 2, as shown in Fig. 3, in a manner generally similar to the methods commonly used when covering a base alone. The cover sheet 4 is generally crossshaped, with a central section adapted to cover the bottom of the base 1 and arms adapted to extend up the sides of the assembled base 1 and neck 2. Note that a portion 4a of the sheet material just above the upper edge of the base 1 extends smoothly over from the outer surface of the base 1 to the outer surface of the neck 2. The sheet material 4 is provided on its inner surface with an adhesive coating, so that when it is assembled as shown in Fig. 3, it sticks to the base 1 and neck 2. The portion 4a, however, is not stuck.

In a concurrent operation, the sheet 5 of decorative material is assembled over the cover 3.

As shown in Fig. 3, the sheets 4 and 5 have their ends projecting beyond the edges of the neck 2 and the cover 3. The next step is shown in Fig. 4 and consists in folding these ends over the edges of the neck 2 and the cover 3. This is a common step, well known in the art.

The next step is to move the neck 2 downwardly against the bottom of the base 1, to the position shown in Fig. 5. During this movement, the portion 4a of the sheet material is carried around the upper edge of the base 1 and forms a fold with an adjacent portion 41; of the sheet material, that fold being located between the inner surface of the wall of the base 1 and the outer surface of the wall of the neck 2.

If desired, a somewhat neater appearance of the finished container may be achieved by placing a block within the neck at this time, and pressing the sides of the base and neck assembly against that block, thereby firmly adhering the portions 4a and 4b of the sheet 4 to the base 1 and neck 2, respectively.

Note that because of the folds 4a, 4b, the wall of the base 1 is located farther out from the neck 2 than would otherwise be the case, thus providing a wider ledge at the top of the base 1 than would be obtained with separate cover sheets on the neck 2 and the base 1. That is to say, the presence of the fold between the portions 4a and 4b of the sheet 4 itself increases the spacing between the neck 2 and the base 1.

The container is now ready for assembly of the cover 3 thereon, as shown in Fig. 5. The dimensions are selected so that the neck 2 fits tightly into the cover 3, i. e., with sufficient friction to hold the assembly together.

The sheet 4 of covering material need not necessarily be decorative in the sense that it carries any ornamental pattern, but may simply be a sheet of plain paper designed to improve the appearance of the box as compared to the appearance of a box of uncovered paperboard.

The sheet 4 not only serves its function of improving the appearance of the box, but also provides a siftproof seal between the neck 2 and the base 1, so that powdered or granular material within the container cannot leak out.

Figs. 6 and 7 In the containers of this general type which have been known in the prior art, it has been difficult to provide coordinated registering decorative patterns on the outside of the neck 2 and the outside of the base 1. In a box constructed in accordance with the present invention, such coordination of the decorations on the neck and base is simple.

Fig. 6 shows the appearance of one of the walls of a neck and base, when assembled as shown in Fig. 4. The sheet material 4 is provided with a decorative pattern, shown by way of illustration as comprising three letters 6, consisting of upper portions 6a and lower portions 6b, these portions being spaced apart by blanks corresponding to the fold portions 4a and 4b of the sheet. When the neck and base sections are finally telescoped together, in the position of Figs. 5 and 7, the two spaced portions of the letters are brought together so that the two decorative patterns are coordinated. Since the two patterns are on the same sheet of paper, they are not subject to misalignment due to unequal shrinkage of the paper or mishandling of the separate sheets of paper during assembly.

The operations described above may be carried out by hand or by automatic or semi-automatic machines.

Various modifications of the box structures illustrated may be employed. For example, the box could have a flanged bottom or top, known in the trade as an extended bottom or top; the outer walls might taper inwardly toward the bottom; or the cover might have a domed top.

While certain preferred embodiments of the invention have been illustrated and described herein, other modifications thereof will readily occur to those skilled in the art, and it is therefore intended that the invention be defined by the appended claims.

What is claimed is:

l. The method of manufacturing a container covered with sheet material, comprising placing an inner telescoping container section partly within an outer telescoping container section, so that the sections overlap, applying an adhesive surface of a sheet of material smoothly across the adjoining portions of theouter surfaces of the partly telescoped sections with the portion of the sheet facing the inner section near the edge of the outer section spaced from said inner section, thereafter moving the inner section farther into the outer section so as to carry said spaced portion of the sheet around the edge of said outer section and into contact with the inner surface of the outer section, said portion of the sheet then cooperating with an adjacent portion of the sheet adhering to the inner section to form a fold in the sheet between the sections and to hold said sections firmly in a fixed relationship determined by the double thickness of the sheet material forming said fold.

2. The method of manufacturing a container as defined in claim 1, in which said outer section has an end wall and said farther movement of the inner section brings its end against said end wall.

3. The method of manufacturing a container as defined in claim 1, in which said sheet material has spaced decorative patterns which are brought into cooperative relation when said spacing portions are moved to form said inner fold.

4. The method of manufacturing a container as defined in claim 1, including the further step of pressing said outer and inner sections firmly together.

5. The method of manufacturing a container covered with sheet material, comprising placing an inner telescoping tubular container section partly within an outer telescoping container section having an end wall, so that the sections overlap, applying an adhesive surface of a sheet of material smoothly across the adjoining portions of the outer surfaces of the partly telescoped sections with the portion of the sheet facing the inner section near the edge of the outer section spaced from said inner section, thereafter moving the inner section farther into the outer section and against said end wall, so as to carry said spaced portion of the sheet around the edge of said outer section and into contact with the inner surface of the outer section, said portion of the sheet then cooperating with an adjacent portion of the sheet adhering to the inner section to form a fold in the sheet between the sections and to hold said sections firmly in a fixed relationship determined by the double thickness of the sheet material forming said fold, covering a second outer telescoping container section having a second end wall with a sheet of decorative material, said second section having a clearance over said inner section substantially equal to said spaced relationship so that the second section may serve as a removable cover, and placing said covered section over said inner section so that the outer surfaces of said outer sections are aligned.

6. A container comprising a double wall including inner and outer layers of paperboard, the inner layer projecting beyond an edge of the outer layer, and a covering of sheet material for said wall, said covering comprising a first portion adhesively attached to the outer side of the innermost layer adjacent said edge of the outer layer and extending between said inner and outer layers, and a second portion forming a fold with said first portion and adhesively attached to the inner side of the outer layer adjacent said edge and to said edge, said portions cooperating to hold said layers firmly in a fixed relationship determined by the double thickness of the sheet material forming said fold.

7. A container as defined in claim 6, in which said sheet material comprises a third portion adhesively attached to the outer side of the outer layer adjacent said edge, said first and third portions having registering decorative designs formed thereon.

8. A container as defined in claim 6, comprising a cover including a top and side wall means adapted to telescope over said projecting portion of the innermost layer to a position in alignment with and abutting said outer layer.

9. The method of making a double-walled container covered with sheet material, comprising placing two container wall sections in overlapping relation, applying a sheet of adhesively coated material smoothly across the adjoining portions of the overlapped sections so that a first portion of said sheet material adheres to the outer surface of the overlapping section, a second portion adheres to the outer surface of the overlapped section, and an intervening portion between said first and second portions is spaced from both said sections, and thereafter moving the wall sections relatively to one another in a direction to increase the overlap, thereby carrying said intervening portion of the sheet around the edge of the outer section and into contact with the inner surface of the outer section, said intervening portion of the sheet then cooperating with said second portion of the sheet to form a fold in the sheet between the sections.

10. A container comprising a base section and a neck section, said neck section being telescoped within said base section with its upper end projecting therefrom, and a covering of decorative sheet material for the telescoped walls of said neck and base sections, said covering comprising a first portion adhesively attached to the outer side of said upper end of the neck section and extending between the neck section and the margin of the base section, a second portion forming a first reverse fold with said first portion and adhesively attached to the inner side of the base section adjacent its edge, a third portion forming a second reverse fold with said second portion at said edge and attached to the outer side of said base section, said portions cooperating to hold said neck and base sections firmly in a fixed spaced relationship determined by the double thickness of the sheet material forming said first reverse fold.

11. A container as defined in claim 10, comprising a cover section telescoped over said neck section, said cover and neck sections having a clearance between them substantially equal to said spaced relationship, so that the outer surfaces of said cover and base sections are aligned.
