The binding, the frame member and the sheet of transparent material are also preferably secured togetherby an adhesive such as cement which will work through the thread needle holes in the binding andmake a solid uniform combination structure of binding, Celluloid and wire. The arrangement of the stitches very close to the wire form and the cementing of 'the binding, the Celluloid and the wire form results in a firmer, tighter non-slipping form in the binder and provides a stiff construction for reinforcing the transparent walls and for main n the same in their true original shape, whether the receptacle is cylindrical or any non-circular or poly onal form.

Transparent walls 4 are fitted within and secured'to a bottomsection comprising an opaque bottom It of well seasoned cardboard or other suitable material and an upstanding rim [5 of shrinkable material such as single ply or laminated cardboard or analogous material such as wood veneer. The upstanding band l5 which is arranged exteriorly of the transparent walls is secured to the peripheraledge of the bottom l4 preferably by cement or other adhesive material and the bottom I4 and the upstanding band or rim are covered with decorativepaper It or other suitable material such as cloth. In the construction of the bottom sectionv the opaque bottom is die-cut to the desired shape and the material forming the rim or upstanding band is cut to exact length to fit snugly around the edge of the bottom. .The opaque bottom I is of a diameter slightly greater than the body and extends slightly beyond the outer face of the bottom binding l0, and this in conjunction with the outer portion of the binding Ill offsets the band l5 from the plane of the flexible transparent walls 4 of the body portion prior to the shrinking of the band on the body portion, and the upper edge of the outer portion of the lower binding It forms a shoulder exteriorly of the transparent wall 4, so that when the band I5 is shrunk on the body portion the band will engage said shoulder of the lower binding In and interlock the band with the body' portion of the container. The paper or veneer band is of such construction and consistency as to shrink considerably when allowed to dry after being'wet. One edge of the rimtaken to keep all measurements constant so that when the wire-formed side wall is inserted in the bottom section it will fit accurately and tightly against the wet side of the bottom, so that as the upstanding band ll starts to dry and to shrink it closes tightly around the inserted wire form. This shrinkage of the projecting portion of the rim against the transparent wall, in addition to securely clamping the opaque bottom to the wire bottom form so that no cement is really required to hold' the side wall firmly and securely in the bottom section, also fills in and closes the space between the transparent side wall and the inner face of the projecting portion of the upstanding rim making a smooth connection between the transparent wall and the bottom section and materially enhancing the appearance of the container.

The wire for the transparent wall is cut to the exact length and formed to the desired shape before the ends of the wire are welded together and the wire forms are always constant for each size of container. In applying the Celluloid or other transparent sheet to the forms or frame members! and 8 one end and one edge of the transparent sheet is properly arranged on one of the wire forms and the stitching of the binding to the transparent sheet and wire form is commenced. This stitching is continued until the entire form has been covered and a suitable overlap of the binding stitched chat the point of closure. The necessary lap for joining 0r cementing the seam andjolning the transparent side wall is then in proper position for cementing. Itis necessary and desirable tolwait until the stitching has been applied to at least one edge before cementing the overlapped edges of the sheet because the stitching close to the wire form or peripheral frame member produces a constant tension on the transparent sheeting. This is done to obtain a straight and true shape without wrinkling the side wall when, stitched.

-mented. This method produces a taut, tight and true shape side wall without wrinkles or other imperfections whlch'would mark the appearance "and affect the saleability of the merchandise.

forming band is in contact with the edge of the bottom and consequently after it has been wet with glue containing water it cannot shrink because it cannot compress the stiff well-cured bottom piece 14.. The portion of the upstanding rim above the bottom piece shrinks considerably and such shrinkage when complete produces a decided and definite .inward pitch to the upwardly projecting portion of the rim from the bottom piece to the top edge of the band and this shrinkage is utilized for interlocking the band with the upper edge of the outer portion of the lower binding ill and firmly and securely fastening the transparent walls to the bottom of the container. Soon after the band is wet with glue and moisture in the assembly of the bottom section and the application of the decorative pap'er or other material and before the bottom section has started to shrink permanently or materially the wire reinforced side wall is inserted and at the same time glued with strong cement to the bottom and part way up the side wall. Care is The other wire form or peripheral frame member is then stitched in a similar mannerand the seam or overlap of the ends of the transparent sheet is then cemented together making a strong, tight and true form or shape of the Celluloid or other transparent sheeting.

If additional strength isdesired then a very strong combination of binding, thread, transparent side wall and wire peripheral frame member is formed by applying cement with suitable solvents tothe' binding at the point of stitching as heretofore explained... The cement which enters the binding where it is perforated by the needle not only forms a solid bond between the transparent sheeting, thread and binding with the wire frame member but it also closes any rupture in the transparent sheeting where the same is pierced by the needle and thereby making the sheeting even stronger at this point than anywhere else in the side wall.

The time required for maximum shrinking of the bottom band or rim l5 varies with weather conditions and the type and quality of decorative covering employed. Usually, however, shrinkage is practically complete at the end of 26 hours and the container is ready to ship.

The cover is made in "substantially the same manner as the bottom section except that shrinkage of the side band or rim ll on the top.

wall or die-cut piece ll of opaque material is not necessary for construction purposes. The rim i1 and the opaque top wall I. are covered with suitable decorative material I! and the cover is designed to have a loose fit on the transparentside wall I,- but should it be desired to permanently secure the top wall to the transparent side wall the rim I! may be shrunk on the transparent side wall in the same manneras the rim of the botton section. The permanently attached top wall' or cover is designedto be employed where access to a container is provided at some other point ,and by some other means such as an opening in ripheral frame members of the form of the container, a sheet of thin flexible transparent material impervious to liquid secured to theupper and lower frame members to form a body por-' tion, and a bottomsection composed of an opaque bottom and an upstanding rim having a definite inward pitch and shrunk on the lower end of the body portion, said body portion and rim having cooperating means for interlocking the rim withthe body portion.

2. A container including a body portion comprising upper and lower frame members of the form of the container, a sheet of transparent material stretched on the upper and lower frame members sufllciently to take up all slack, ,a-binding securing the transparent sheet to eachof the frame members and tensioning the said sheet and forming an exterior shoulder at the lower end of the body portion, said frame members maintaining the container in its original shape at all times, and a bottom section having an upstanding rim receiving the lower end-of the body portlon and shrunk on the same in intimate frictional engagement with the transparent sheet andinterlocking relationwith the exterior shoul- 3 der of the binding of the lower frame member.

- tensioning the same sufficiently to take up all y i 3. The method-of making a cylindrical container which. consists in stretching upon separate and independent upper and lower rigid circular ring-like forms a thin sheet of flexible material havi-ngjthe' characteristic of Celluloid and impervious to liquid, securing the sheet of material to the outer peripheries of said formsand slack and'eliminate wrinkles thus providing a closed cylindrical side wall structure, arrangingagainst the lower end of the body portion a disklike bottom section having an upstanding rim of shrinkable liquid absorbent material fitting closely against the exterior of the lower rigid form and in a moist condition and containing an adhesive, and allowing the-moist rim to shrink and firmly engage the lower rigid form and side wall structure thus deforming the latter inwardly above the lower circular form and forming an interlocking connectionbetween the rim and the body portion for" permanently securing the bottom section to said body portion.
