9 Claims. (01. 229-31) This invention relates to containers preferably body shell 2 of paper tubing protectively lined, of paper, fiber, or similar material, adaptable or internally coated with a coating 3 preferably for either solids or liquids, and to be easily sealed of thermoplastic and liquid-resistant character hermetically. In forms of construction such as like Bakelite or other synthetic resin, and has hereinafter described, the container is amply end walls 4, 5 of cardboard or fiber board in the strong and rugged as against injury in handling ends of said body 2.

This hole V, or holes, is, or are, located 5 I e container 1 here illustrated comprises a at that end of the tube section destined to become The bottoms 4 are, preferably, made in the form of cardboard discs having applied facings of Cellophane 6 on one side, of larger diameter;

or saidbottoms may be produced from two or three-ply strip paper or fiber'glued together with a cover of Cellophane suitably adhered to one side thereof. In practice the cardboard discs 4 1 and applied, relatively larger diameter, Cellophane facings 6 are suitably treated to effect fianging of said facings around the discs 4, as indicated at I.

In applying the bottom 4 to the tube section 2,

the former is heated to a temperature of from 230 to 250 Fahrenheit and suitably forced into the lower body section end, which at this time is plain and open like the upper end, as shown in Fig. II. This heating of the bottom 4 is done in order that as said bottom enters the section 2 and is forced into the section 2, theheat transmitted shall sufficiently soften the coating 3'to permit its being pushed forward by the bottom 4 to form a surrounding concaved head or definite fillet 9 of the coating substance. This fillet 9 constitutes, by impervious adherence to the-"Cellophanef covering 6 of the bottom 4, a leak-proof sealing-juncture between the container wall and its bottom end. 'In order to mechanically reinforce the parts 2 and 4 when united as just de scribed, the end of the former may preferably be suitably spun over and inwardly as indicated at In, so as to not only strengthen the bottom of the container I, but also to overlap and form a supplemental sealing juncture with the flanged edge I of the "Cellophane facing 6, in a manner obvious from the foregoing description relating to formation of the sealing-juncture fillet 9. forcing the bottom 4 into position in the tube section 2, some of the'coating 8 is left between the *Cellophane" flange 1 and the inside of said section, constituting a further sealing-juncture.

The container I is now ready for filling with a.

measured quantity of liquid H, such as an oil for example, to a level below the vent hole V,

whereupon the top end closure or cover 5 is applied and forced in,in the same manner as explained in connection with the bottom 4. The closure 5, shown separately in Fig. IV, consists of a cardboard disc having a Cellophane facing 6 flanged at 'l as before set forth; but this top disc is, preferably, formed with a concentric V groove l6 which, when the closure 5 is applied, extends from its underside well towards the exposed upper surface as indicated-at l1, whereby the inner central portion 8 can be readily removed by a suitable cutting implement applied to the part II, in an obvious manner.

It is to be particularly noted that as the closure 5 is forced into closure-position as shown in Fig.

III, it not only forms a sealing-juncture fillet [9 corresponding with the bottom fillet 9, but during its passage inwardly over the vent hole V it will force out or evacuate substantially all air inter- GS vening the top of the liquid H and the underside of said cover. Furthermore, it is to be remarked that if a suitable exhausting means be applied to the vent hole V during application of the closure 5, a non-pressure sealing of the con- 7 tainer I can be effectively accomplished, while said closure is being forced home. Still further, it will be understood that the central portion -8 of end wall 5 may be removed without cutting through the Cellophane facing 6, for

76 the purpose of inspecting the liquid content H if desired, and may be reinserted to protect said facing from damage or fracture; whereas, when it is desired to empty out the liquid II, the Cllopane facing 6 below the portion 8 can also be removed by a suitable implement, and the content poured out, or otherwise discharged from the container I. Also, after the closure 5 is applied, the upper edge of the container I may be spun over inwards at 20 as and for the .purpose explained in connection with its bottom end 4.

In the modified form of construction shown in Fig. V, the cover closure 5a is made of the same material as the container body 2 and flanged circumferentially at 2| for stiffening purposes, but in all other respects said modification corresponds with the description of Figs. I-IV; similar refer ence characters being applied with the exponent a to obviate repetitive description.

It is further to be understood the outside of the container body 2, as well as the outer surface of the bottom and closure members 4, 5, may preferably be waxed or otherwise treated to render them waterproof and moisture resistant.

Incidentally, it is to be understood that the M Cellophane facings 6, 6 may be dispensed with, and the closure and bottom pieces 4, 5 formed of thermoplastically coated material, with corresponding formation of the leak-proof sealingjunctures 9 and I9, without departing from the fundamentals of this invention.

Obviously, the container body 2 may have an applied liner of .Cellophane in the form .of a tube and the bottom and top discs 4, 5 coated with a thermoplastic, and inserted in the container as hereinbefore described, with corresponding formation of the leaf-proof sealing-junctures with said Cellophane lining. Also, both the bottom and top pieces 4, 5 may be provided with removable inner portions 8; or said discs may be made in the form of annulae or without the removable inner portions 8. In inserting the bottom 4 or the top 5 into the body 2, heat may of course be applied around the ends of the latter to soften its thermoplastic coating 3, rather than to said ends 4 and 5. i

The container I particularly illustrated in Fig. VI resembles-that of Figs. I-IV in having a paper body shell 2 internally coated with thermoplastic 3, preferably of moisture, oil, and air-proof character, affording an impervious lining. The inserted end walls or bottom and top discs 4, 5 have each a facing 6, on one side and around its peripheral edge, of moisture, oil, and air-proof sheet material that is preferably translucent or transparent,-such as Cellophane or the like, for example,-affording impervious linings, Either or each end wall 4, 5 is formed, during manufacture, with an aperture .I8 for which a snugfitting plug-like closure 8b (Figs. VII and VIII) is provided, preferably of the same material as the rest of the end wall 4 or 5. Thus it is un necessary to out an end wall 4 or 5 in order to remove the cover portion 8b, asdescribed in connection with Figs. I-IV. Only a comparatively small amount of adhesive 22 is required for securing the facing 6 to an annular disc 4 or 5. The closures 8b are preferably not secured to the facings 6. The adhesive 22 may beapplied over just the right areas by suitable annular means, assuring against the presence of adhesive between the closures 8b and the linings 6.

In the use of the containers I (especially for oils or other liquids), the plugs or covers 8b are readily removed with the aid of a knife-blade or the like, permitting the contents to be looked through (if permeable to light) by holding the container up to the light. To facilitate removal, each plug or cover 81) may have achampfer or bevelled undercut in its edge as indicated at 23 in Figs. VII and VIII, so as to afford .a convenient hold for a finger-nail or a thin edge of any sort. After inspection of the container contents, plug(s) or cover(s) 8b can then be replaced to protect the facing(s) 6 over the window(s) formed by the opening(s) l8. The covers 8?) are also useful to sustain the linings 6 against pressure of heavy substances in the container; but they are capable of yielding to allow some expansion or contraction of air in the container I, for example, and would be blownout by internal pressure sufficient to rupture the linings 6, far below the point of dangerously high pressure.

The container I particularly illustrated in Fig. IX differs from that in Fig. VI in that the body shell 2 has internal annular shoulders adjacent its ends, shown as formed by inward offsets rolled or otherwise formed in the shell wall. These shoulders 25 provide seats for the edges of the bottom and top ends 4, 5, and afford greater area and strength for the cementitious joints 9 and I9. Accordingly, the spinning over of the body-shell ends as preferably resorted to in the constructions of Figs. I-VIII is not shown in Fig. IX,--although it might, of course, be used in this construction if desired. In manufacture, also, the shoulders 25 are advantageous to prevent the ends 4, 5 from being pushed into the shell 2 too far.

Iii Figs. VI-DI, various parts and features are marked with the same reference-numerals as in Figs. I-V' (with an added letter, where such distinction appears desirable) as a means of dispensing with repetitive description.

From the foregoing description, it is thought the merits and advantages of the invention will be fully appreciated, and while specific embodiments thereof have been minutely explained, the

same are not to be taken as conclusive, inashaving a thermoplastic inner coating and an orifice near one end through its wall; push-in much as modifications in details will suggest themselves to those conversant with the art. Accordingly, it is intended to hereby include all such variations of the invention as fairly come within the scope of the following claims.

Having thus described my invention, I claim: 1. A container comprising a tubular body shell faced ends; and inward retroversions of the tubular body extremities reinforcing the container ends.

4'. A container consisting of a tubular body portion having a thermoplastic lining, push-in ends facedwith a transparent covering adapted when inserted to form definite sealing fillet juncture between the body portion lining and said ends, and means providing sight apertures through the container for inspection of its content.

5. A container consisting of a tubular body portion having a thermoplastic lining, push-in ends faced with sheet Cellophane or the like adapted for fusible definite fillet union with the lining, and a removable section in one end affording access to the Cellophane facing.

6. A container consisting of a tubular body portion having a thermoplastic lining, push-in disc ends covered with sheet Cellophane or the like on their inner surfaces and adapted for fused definite fillet union with the lining, each said end having an opening therein normally-closed by saidcovering, and a plug removably engaging in each opening.

7. The combination of claim 6 wherein the removable plug is provided with an arcual tapering section for aiding in its removal from the container end.

8. As an article of manufacture a push-in end of the type described for paper containers and the like, said end having an opening therein, an

internal covering of transparent material for said end, and a plug removably engaged in the opening for exposing the transparent covering.

9. A container for liquids comprising a tubular body of paper or fiber having a thermoplastic inner lining, push-in ends'of cardboard with inner facings of sheet Cellophane flanged outwardlythereabout, said ends, when forced into place, displacing part of the body lining to form inner leak-,proof definite sealing fillet junctures between the body wall lining and Cellophanefaced ends; and inward retroversions of the tubular body extremities reinforcing the container ends; one of said ends including a readily removable section to afford access to its Cello phane" facing.
