2 Claims.

- being such that after the container has been opened, the closure can be used as a cover for the container.

One object of the invention is to provide a novel closure which can be readily applied to the container body for sealing the container under vacuum conditions when the container is to be vacuum packed.

Another object of the invention is to provide a novel closure which is so constructed that when the filled container is in the vacuum chamber, the final sealing of the container under vacuum conditions can be accomplished simply by forcing the closure member firmly against the open top of the container body.

Further objects of the invention are to provide various novel features relating to containers of this type which will be more fully hereinafter set forth and then pointed out in the appended claims.

In the drawings:

Fig. 1 is asectional view showing a sealed container embodying my invention.

Fig. 2 is a sectional view of the cap portion of the closure.

Fig. 3 is a sectional view of the band portion of the container.

Fig. 4 is a view illustrating the cap portion and band portion of the closure assembled ready to be applied to the container for sealing the latter.

Fig. 5 is a side view of the sealed container.

Fig. 6 is a sectional view similar to Fig. 1 but showing the tear strip removed and the container opened.

Fig. 7 is a sectional view similar to Fig. 1 but showing a modified form of the invention.

In the drawings the container body is indicated at I, and it may have any suitable or usual shape except that it is provided at its upper open end with an exterior head 2 and also with a, downwardly facing exterior shoulder 3 below the bead. The container herein shown is one having a neck portion 4, the bead 2 and downwardly facing shoulder 3 being formed on the neck portion. The exterior surface 5 of the neck between the bead 2 and the shoulder 3 tapers outwardly slightly from the bead to the shoulder so that the exterior diameter of the neck at the shoulder 3 is slightly larger than it is immediately below the bead 2.

The sealing closure for the container comprises a cap member 5 and a band member I, both of these preferably being made of sheet metal. The cap 6 is shown as formed with an annular groove 8 adapted to fit over the top edge of the neck 4 and adapted to receive a gasket or sealing compound 9 which engages the top edge of the neck to m'ake'a tight joint.

The cap member 6 is also provided with a depending skirt portion ID, the lower edge of which is preferably rolled into a bead I I for the purpose cf eliminating a raw edge. The band member 1 is initially made in cylindrical form and of a size to fit snugly with the skirt ID of the cap member 6. The lower end of the band member is formed with an interior bead I2. this being provided for by rolling the edge of the band member over as indicated in the drawings. Said memthe closure are assembled and united together before they are applied to the container body. These two elements are connected by inserting the upper end of the band member. I into the skirt Ill of the cap member and then beading two members together near the upper edge of the band member. One way in which this can be accomplished is to operate on the assembled cap member and band member with a beading machine which will roll a bead I5 into the skirt Ill and upper end of the band member. As shown in Figs. 1 and 4 this bead I5 is an outwardly bulging bead which provides an annular groove It on the interior of the band. In forming the outwardly bulging bead I5 the band member I and skirt 6 are deformed so as to provide an interior annular rib I! on the inside of the band directly below the groove I6.

Where the band element and cap member are beaded together in this way the bead will be so formed that when the closure member is applied to the body member, the groove It will register with the exterior head 2 on the container body, and the interior rib or bead I! will lie directly underneath said exterior bead 2. The band is also of such dimension that when the closure is applied to the container body, the interior bead I2 at the bottom of the band member will fit snugly underneath the downwardly facing shoulder 3.

swung back into a closed position as shown in full lines Fig. 6, and when this is done, the interior bead I! or [5a will again snap over the bead 2 of the container, thereby looking or holding the cover in its closed relation.

I claim:

A container comprising a container body having an open top and provided with an exterior head at its top edge and also provided with an exterior downwardly facing shoulder below said bead, the exterior diameter of the container body immediately above the downwardly facing shoulder being slightly greater than at said exterior bead, and a closure for said open top which comprises both a cap member -and a band member, the latter encircling the upper portion of the container body and having its upper edge adjacent the top edge of the container body, said cap member having a depending skirt and the upper end of the band member'being inserted into said skirt and being beaded thereto in a manner to form an interior bead on the band member which underlies the exterior bead at the top of the container body, said band member also being provided with an interior bead at its lower edge which underlies said downwardly facing shoulder, the lower portion of the band member being held in a slightly stretched condition by the larger diameter of the container immediately above said downwardly facing shoulder whereby the interior bead at the lower edge of the band member is held in firm engagement;

with said downwardly facing shoulder, said band member having two spaced score lines forming between them a tear strip which can be torn out outwardlyslightly from the exterior bead to said shoulder, and a closure for said open top which comprises a cap member and a band member, the latter encircling the upper portion of the container body, said cap member having a depending skirt and the upper end of the band member being inserted into said skirt and being beaded thereto in a manner to form an interior head on the band member which underlies the exterior head at the top of the container body, said band member having at its lower edge an interior bead which underlies said downwardly facing shoulder and also having two spaced score lines between the said two interior beads forming between them a tear strip which can be torn out for opening the container, the portion of the band below the score lines being in a slightly stretched condition due to the increased exterior diameter of the container body resulting from the tapered shape whereby said lower portion of the band is held to the container body by a tight friction fit.
