2 Claims.
The invention relates to new and useful improvements in a fiber container and more particularly to a means for closing and sealing the same.
An object of the invention is to provide a fiber 5 shoulder and ensure a tight sealing of the disk to container having a filling opening which is the body welladapted to be closed and sealed by a fiber plug. The closure disk 4 is provided w a openin "A further object of the invention is to provide .9 therethrouehs ted n the p ning is an a fiber container of the above type wherein the I eyelet Ill pre b y of metal, alt oug it may he filling opening isv defined by an eyelet which is 'made of other rigid material The eyelet has a rigidly attached to the end closure member. flange ly ctin the outer face of the A further object of the invention is to prodisk, and a flange l2 preferably formed by rivetvide a closure means of the above type wherein ing to snu y engage t e inner face 0f the disk. the fiber plug is cup-shaped and provided with a e disk at e ate ed e p o f t e flange for limiting the extent to which the plug op is a ped b tween t ese flan es H and can be inserted in the eyelet for closing the conand this makes a y tight a d Connection t i between the eyelet and the disk. If desired, a A still further object is to provide a closure sealing material could be placed between the edge plug of the above type wherein the closed end of Of the Opening d the y let for ensuring a very the plug extends into the container beyond the tight s end of the eyelet and wherein means is provided This Opening through the eyelet may be utilized for expanding the closed end and holding it in its for t e filling f the container. For most p odexpanded condition for sealing the container. uots the opening may be ad pa atively These and th bject 111 in part be obvious, small. After the container has been filled with and will in part be hereinafter more fully disthe p then the Opening through the eyelet closed. is closed by a fiber plug [3. This fiber plug is In the drawing, which shows by way of illuscup-shaped and is provided with a flange l4, t t one embodiment f t invention, which limits the extent to which the plug can Figure 1 is a view partly in id elevation and be inserted in the eyelet. The lower or closed partly in vertical section showing a container end of the p projects inwardly a Short disto which the improved closure means is applied. ta e b y d t flange Located in t s cup- Figure 2 is aplan view of the sam shaped plug is a concave convex metal plate 15. Figure 8 is a view on an enlarged scale thr When it is desired to close and seal the container, a portion of the closure disk and the eyelet the p is p b y ated W h a suitable admounted therein and providing a fillin opening hesive and then inserted in the eyelet. After the for the container. plug has been firmly seated with the flange 15 Figure 4 is a vertical sectional View through the against the flange ll f the y t en a tool fiber plug for closing and sealing the opening may be i s d in the p s a d the tal p at inthe eyelet. l5 pressed upon and forced to a fiat position, as Figure 5 shows the plug inserted in the eyelet 0 s w n Fi This plate is a mpa v ly and the inner end of the plu expanded for l kthin plate and can be deformed into the position ing the plug in place and sealing the container. shown in Fig. 5 with comparatively little pres- In the drawing there is illustrated a fiber consu s straighteningr out of e p ate 5 will tainer consisting of a body portion I which may pand the inner end of the p u be made by spirally winding, convolutely Winding The plate is dimensioned relative to the openor in any other suitable way. The body wall is ing u h t e y t so that when the p u is provided with an inwardly projecting bead 2 p d d the peripheral portion it of the p forming a shoulder 3 on which a closure disk 4 is will be f t y larger d t t a the p nmounted. After the disk is placed, then the upper ing through t t, and this a p h s tw end of the body wall is turned inwardly over the functions In t e fi place, it w hold t e p disk as indicated at 5. As a means for firmly sefirmly Seated in the y d in the Second curing the disk to the body portion of the cona e, t w cause the p t be d aw nto tight tainer, a metal ring 6 rolled into a bead 1 at the sealing contact with the eyelet and thus ensure lower side thereof and into a bead 8 at the upper an hermetic sealing of the container. side thereof is placed on the container. The head 56 The container described above is very rigid and 1 is nested in the bead formed in the body wall and the bead 8 is placed at the inturned edge of the body wall, and preferably bears against the disk. This will firmly clamp the disk against the is very tightly sealed, and therefore is especially adapted for paints and similar liquid products. The end disk 4 is attached to the container by the manufacturer of the container and the final closing of the container which occurs after the product is placed in the container is of such a simple structure that it can be readily applied and tightly sealed by unskilled operators.
While a sealing material has been described as used in connection'with the eyelet, and an adhesive used in connection with the plug, it will be understood that for certain uses of the con-' tainer the sealing material and adhesive may be omitted. The eyelet is mechanically secured to the container end and the closure plug is mechanically secured to the eyelet for closing the container. While the plug is described as made of fiber material, it will be understood that any kind of material may be used such as metal, rubber, or .the like, but it is essential that the material used shall be capable of being expanded for the securing of the plug to the eyelet without rupturing the material.
It is obvious thatmany changesin the details of construction may be made without departing from the spirit of the invention as setforth in the appended claims.
I claim:
,1. A fiber container having anend closure disk provided with an opening therethroug h, an eyelet secured to said disk in this opening, a cup-shaped plug adapted to be placed in said eyelet for closing and sealing the container, said plug having a flange at its outer end for limiting the extent to which the plug is inserted in the eyelet, said plug being dimensioned so as to project into the container beyond the eyelet, and means disposed within said plug for expanding the inner end portion of the plug projecting beyond the eyelet to a diameter larger than the diameter of the eyelet for firmly attaching the plug to the eyelet and sealing the container.
2. A fiber container having an end closure disk provided with an opening therethrough, an eyelet secured to said disk in said opening with the flanges of the eyelet overlying the inner and outer faces of the disk, a sealing material disposed between the eyelet and the disk, a cup-shaped plug adapted to be placed in the eyelet for closing the container, said plug having a flange at its outer end, for limiting the extent to which the plug is inserted in the eyelet, said plug being dimensioned so as to project into the container beyond the eyelet, an adhesive sealing material disposed between the plug and eyelet for sealing the same and means disposed within the plug for expanding the inner end portion of the plug projecting beyond the eyelet to a diameter larger than the inner diameter of the eyelet for firmly drawing the plug into contact with the eyelet and sealing the container.
