2 Claims.

This invention relates to containers of that type comprising a body member and a removable end member which, after the container has been lled, is sealed to the container body with a hermetic seal and which is so constructed that the container may be opened for the discharge of its contents by tearing out a circumferential tear strip, thereby permitting the 'end member to be removed, said end member being constructed so that it can be again replaced on the container body with a friction flt.

One of the objects of the present invention is provide a novel container of the type in which the body member is made of vitreous materials such as glass, or plastics, or some other suitable non-metallic material, while the removable end member is made of sheet metal.

In order to give an understanding of the invention, I have illustrated in the drawings some selected embodiment thereof which will now be described, after which the novel features willbe pointed out in the appended claims.

Fig. 9 Lis a fragmentary sectional view showing my invention as applied to a container having walls of paper or bre.

Fig. 10 is a side view of Fig. 9.

Fig. 11 is a sectional view illustrating the container in Fig. 9 after it has been opened.

Fig. 12 is a fragmentary sectional view of a different embodiment of the invention.

In my improved container shown in Fig. 1, the body member 3 having the side walls 4 and bottom 5 may be made from glass or plastics or any other suitable non-metallic material. member 6 is made of sheet metal and itis formed with a depending vertical wall 'I which tits within the upper end of the body 3 with a friction t.

In order to provide for sealing the end member 6 to the body 3 when the container is ilrst filled, I propose to employ a metal band 8 which encircles the upper endof the body 3 and is permanently secured thereto. This band B is initially provided with a laterally extending sealing ange 9 and the end member 6 is also initially provided at its periphery with a sealing ange I0, as shown in Fig. 3.

After the container has been l1ed,.the'end member 6 is assembled with the body 3 by inserting the depending wall 1 into the open top of the body 3 and positioning the sealing flange I0 thereon against the sealing ange 9 of the band 8. These two sealing flanges are then rolled together in the usual way to form the lock seam II and thereby the end member 6 is secured to the body 3.

'I'he body member 3 is shown as having a downwardly-facing circumferential shoulder I2 and the lower edge of the band 8 is bent inwardly into engagement with said shoulder as shown at I3, thereby locking or anchoring the band 8 to the container body 3. The cover member or end member 6 is formed to present the annular portion I9 which extends outwardly from the upper edge of the wall 1 and overlies and forms a tight joint with the top edge 20 of the body member.

If desired, a suitable gasket or packing I4 may be employed between said portion I9 of the end member 6 and the top edge 20 of the body wall 4, thereby to hermetically seal the container.

The band '8 is formed with two circumferential lines of weakness or score lines I5 and I6 which form between them a tear strip Il that can be torn out of the band when the container is to be opened. This tear strip will be provided with the usual projecting tab I8 to which a key may be applied for tearingthe tear strip from the band 8 as usual in cans or containers that are opened by removing a tear strip from the wall of the container.

The lower line of weakness I6 is situated below the top edge 20 of the container body, and the upper line of weakness I5 is situated no lower than the bottom face of the annular portion I9. When the tear strip Il has been torn out of the band 8, the latter will be divided into an upper portion which is seamed to the cover member 6 by the lock seam Il, and a lower portion which The end remains anchored to the body member. The removal of the tear strip exposes not only the upper edge portion of the body member but also the sealing gasket I4, and after the tear strip has been removed the cover may be lifted from the container by forcing a suitable implement into the space between the annular portion i8 of the end member 8 and the top edge 28 of the container body which is occupied by the gasket or packing strip il. In this way, the end member can be readily pried oi! from the body portion.

Because of the fact that the end member has the depending wall 1 which ilts within the open end of the body with a friction fit, the end member or cover member 6 is a replaceable cover which can be replaced on the container body, and when so replaced it will have a tight ilt therewith.

There is thus provided an hermetically sealed .container having the body portion made of glass,

plastics or some other non-metallic material and which is provided with a replaceable sheet metal cover member of the plug type which when replaced has a friction t with the body.

Some containers of this type. and especially containers of the gallon or 1/-gallon size which are used for packaging paint, are frequently provided with a bail by which they can be carried. Such a bail is shown in Figs. l and 2 of the drawings and this may be provided for by securing suitable ears 2i to the band 8 on the opposite sides thereof and connecting the ends 22 of a bail 28 with said ears in a well-known way.

The use of the band 8 therefore makes it possible noiI only to use a container having a body member of glass or plastic or other non-metallic material but it also provides means by which the container can be opened by removing a tear strip in the usual way, and a container in which the cover member has a friction fit with the upper end of the body member when said cover is replaced theron. The use of the band 8 also makes it possible to equip the container with the carrying bail 23.

'Ihe band 8 will have sufllcient frictional engagement with the exterior of the body member 8 so that said band will retain its place on the body after the tear strip I1 has been remove'd.

In Fig. 6, there is shown a slightly different embodiment of the invention in which the upper edge of the wall 4 of the container body is formed with a rabbet 24 and the end member 8a is formed with the two annular stepped portions 25, 26 one of which rests on the bottom wall of the rabbet 24 and the other of which rests on the top edge of the body. In this embodiment of the invention, the packing gasket 20a is interposed between the bottom face of the rabbet 2l and the step 25. The peripheral edge of the end member 8a is secured to the band 8 by means of the lock seam Il as in the other embodiments of the invention, and said band is provided with the two lines of weakness I5, il which form between them the tear strip i1 as above described with reference .to Figs. 1 and 2.

Figs. 7 and 8 show a construction in which the upper end of the body member 8 has ,afband 8b thereon similar to the band 8 in Fig. 1 'and in which the end member 6b is seamed to the upper edge of the band by means of the lock seam IIb,

In the embodiment shown in Figs. 'I and 8, however, the lines of weakness which are indicated at lib and lib do not extend entirely about the band 8b so that when the tear strip IIb isftoln out of the band, there will be lc'ft a 'portion 21 which connects the can end with the cardboard, etc. In this embodiment, the side wall ofthe container body is indicated at 4c and as stated above. it may be made of nbre, cardboard or some other paper-like product. The upper edge portion of the side wall 4c is folded over on the outside of said side wall as shownat 88 and then is folded or bent inwardly and upwardly as indicated at 8| so that the portion 8l is located between the fold 88 and the wall 4c of the container body. Surroimding the folded portion 88, 8| of the container body is a metal band 8c to the upper edge of which the end member 8c is ,seamed by means of the lock seam llc. said' end member 8c being preferably made of sheet metal. This end member te is made vwith the depending circumferential wall 1c which fits within the open end of thebody and the cover is also madewith an annular portion llc which rests on the top edge of the body.

The band 8c is made with the two lines of y weakness or score lines llc and I8c forming between them a tear strip llc similar to the tear strip I'l in Fig. 1 and which can be tom'from the band when the container is to be opened.

In the construction shown in Fig. 10, the tear strip llc does not extend entirely around the band but is constructed so that when the tear strip is removed from the band, there will be left a portion 21e constituting a hinge for the end member when the container is to be opened as shown in Fig. l1. One end of the tear strip llc is provided with the usual tab I8c which can be engaged by a key or other implement for tear ing the strip from the can.

The lower edge of the band 8c is bent inwardly as shown at lic to engage the under side of the folded portion 80, 3i, thereby to retain the band on the container.

The three-ply formation atl the upper edge of the body together with the band 8c provides a container with a relatively stiif rim at its upper end so that after the container has been opened, the end member 8c can be replaced on the container body with a friction ilt and will quite eil'ectively seal the container again, notwithstanding the fact that the container body is made of paper or fibre.

In Fig. 12, I have illustrated a different embodiment of the invention in which the upper edge of the wall ld of the body is folded out' wardly and back on itself as shown at 38d and then is folded outwardly and upwardly as shown at Sid, the fold 3Id having less vertical dimension than the fold 88d. Surrounding the upper edge of the can body is a sheet metal band 8d to the upper edge of which the end member 6d is seamed by means of the lock seam lid. This end member 8d is formed with the vertical wall 1d that fits snugly within the upper end of the container body. 'Ihe band 8d is provided with the two lines of weakness or score lines ld and ltd which form between them the tear strip Ild that is adapted to be torn out of the band when the container is to be opened.

In this embodiment of the invention, not only is the lower edge Ild of the band bent around underneath the shoulder formed lby the folded portions 30d and 31d, but said band may have its upper portion offset with relation to the lower portion thereby to form the shoulder 33 that engages the top edge of the fold 3 I d.

I claim:

1. A container comprising a body member having a downwardly facing circumferential shoulder on its exterior surface adjacent to its upper edge, a band of sheet metal encircling the portion of the body above said shoulder, the lower edge of said band being bent inwardly to engage said shoulder, a cover member separate from said band and having its peripheral edge seamed to the upper edge of the band, said cover member having a depending annular wall that frictionally ts within the-upper open end of the body member and further having an annular portion extending outwardly from the upper edge of said depending wall and overlying the top edge of the body portion, said band having two circumferential lines of weakness forming between them a tear strip which when torn out divides the band into an upper portion that remains seamed to the peripheral edge of the cover member and a lower portion which remains anchored to the body member, whereby the cover member is free to be lifted to open the container, the lower line of weakness being situated below the top edge of the container body and the upper line of weakness being situated no lower than the lower face of said annular portionL said cover member being replaceable on the body member to occupy the same position it occupied before the tear strip was removed, the friction nt between the depending annular wall of the replaced cover member and the interior face of the body member forming a tight joint.

2. A container comprising a body member of glass having a downwardly facing shoulder on its exterior adjacent to its upper edge, a band of sheet metal encircling the portion of the body above said shoulder, the lower edge of said band being bent inwardly to engage said shoulder, a

cover member of sheet metal separate from said band and having its peripheral edge seamed to the upper edge of the band, said cover member also having an annular portion which overles the top edge of the body member and further having an annular wall depending from the vinner edge of said annular portion, which wall frictionally ts within the upper open end of the body member, a sealing gasket situated between said annular portion and the top edge of the body member for hermetically sealing the container, said band having two circumferential lines of weakness forming between them a tear strip which extends nearly but not entirely around the band, the portion of band between the ends of the tear strip constituting a hinge portion for the cover member, the lower line of weakness being situated below the top-edge of the container body and the upper line of weakness being situated opposite the lower face of said annular portion, said tear strip having a tab by which it may be torn from the band thereby exposing the upper edge portion of the body member and said gasket to permit a suitable implement to be forced between said annular portion of the cover and the top edge of the body member for prying the cover member free from the body member.
