The present invention relates to an improved twee container par icularly adapted for the liquids such as lubricating oil, and principal obj-eat the provision of a discontainer produced from a preformed film peliicle of a rzcateriai such as transparent '"ioplestic rubber hydrochloride having mar-- edges laminated to it and an exterior member provided with a. plurality of through the contents of the inhe!" c cider may be observed.

further object of the invention is to produce a display container which is of simple construction of economic manufacture by a method which involves securing an criflced paper board body-imparting member to an inner preformed continuous him of transparent thermoplastic rubber hydrochloride sheet material and heatsealihg together extensions of the rubber hydrochloride film beyond the paper board member, the sealed extensions being folded over and secured the exterior surface or the paper board member.

Another object of this invention is to provide novel reehforcement to prevent undue distortion of a container in its service.

These and other objects will be evident upon a consideration of the following description or a preferred embodiment of the invention and by reference to the accompanying drawings, in c ue -:3}

"l is a perspective view of a finished package constructed in accordance with the invention and provided with a central reinforcing band.

it has been recognized as desirable to package liquid products such as lubricating oil in flexible lac-aw paper board bodydmparting retypes of containers heretoicre for this purpose. in addition to the flexible container to be r. tht, it is sirabie that the container vie iiiity of 1"" contents. in accordance with the ihv i tion a suitable container providing for visibility is produced from a preformed film or pellicle of a material such as transparent thermoplastic rubber hydrochloride, a sheet of paper, orificed relatively rigid bodyurhparting reinforcing member constructed oi a material such as paper board. The fibre board is preferably scored and embossed with strengthening ribs to stiffen such material, especially around openings.

As shown in Fig. l, a blank for the production of the improved container is produced by local hating on orlficed sheet of paper it to a con tinuous sheet of transparent rubber hydrochloride 5 l. A product on the market which may be employed for the inner cellicle is known at Pliofilm. This thin thermoplastic rubber hydrochloride sheet may be laminated to the paper by application of a suitable adhesive to the latter and then bringing the two webs together under pressure. A suitable laminating adhesive may be produced by dissolving chlorinated rubber in a solvent, or other well known adhesives can be employed as required.

To the resulting laminated sheet is fabricated an external sheet of paper board it. This paper board is provided with longitudinally extending orifices it which provide visibility of the product within thefinished container, it being understood that the paper ill also is oriflced to provide openings in registration with the openings as may be seen in Figs. 2 and 3.

The paper board body-imparting reinforcing member it is of smaller dimensions than the laminated sheet of paper and Pliofilm to provide relatively large end extensions and relatively short side extensions M and I5, respectively.

Preferably, the member I! is embossed about the openings it so as to impart rigidity to the package. Also, the paper board is suitably scored to provide for comer folds.

A first step in the formation of a container from the blanks includes folding the combined rubber hydrochloride, paper, and paper board reinforcing member into the rectangular shape shown in Fig. 4. In this shape the end extensions ll of the paper and Pliofllm come together in the manner shown in Fig. 2 with the rubber hydrochloride side of these extensions in face= to-face relation. It will be noted that the ex= eely employed e ecessity for containers rather than in metallic or other rigid be tensions project beyond the paper board. Eeat and pressure are applied to the paper sides of the extensions II to cause the inner layers of rubber hydrochloride to become heat-sealed into a unitary longitudinally extending seam. This seam then is folded over in the manner shown in Fig. 3 and adhesively secured to one of the adjacent ends 'of the paper board reinforcing member on the exterior surface thereof. The resulting combined tube has the shape and construction shown in Fig. 4. The completed longitudinal seam is provided with a continuous Pliofllm-to-Pliofilm contact and extends to the outside of and beyond the paper board reinforcing member. The extended seam is interlocked with the reinforcing member by attachment to its exterior surface to provide a strong construction and protection for the longitudinal seam.

After formation of the tube in this manner, the tube may be flattened along diagonal lines and shipped to a consumer in such condition. When ready for use, the collapsed tube then is squared and one end is formed in the manner shown in Figs. 5 and 6. That is, opposite sides of the extensions 14 are brought together so that pressure then are applied to the exterior or paper side of the resulting upwardly-extending lip it to provide a unitary seal of a liquid-proof nature. In this manner the extensions it provide an end closure and the end is completed by refolding the lip It over adjacent the end of the container and then folding the extensions I! over on top of the lip as shown in Fig..7. The refolded portions then are secured together and secured to the end of the container by the use of a thermoplastic adhesive.

The container then is filled with a liquid and the unclosed end is sealed in the manner shown in Figs. 5 and 6 to complete the formation of the container.

To provide for an intermediate bracing of the container a band II is folded about the center of the paper board reinforcing member and its overlapping ends are adhesively or otherwise secured together to provide a continuous reinforcing It will be noted that the'structure described is of the package may be observed through the openings It and these openings may be of any In some instances changes in the II may be provided by adhesively securing marginal extensions of paper to the paper board body-imparting reinforcing member.
