ATTACHING MEANS FOR CONTAINER HEADS Filed June 30, 1931 ATT'OR N EY MYQM Patented Feb. 27, 1934 UNITED STATES PATENT OFFICE 1,948,920 ATTACHING MEANS FOR CONTAINER means 2 Claims.

This invention relates broadly to sheet metal containers and more particularly to a pail or can and means for attaching a cover thereto, the type of container to which the invention is best adapted being that in which a curled edge is provided at the top of the container body, such as that shown in my PatentNo. 1,593,638, dated July 27, 1926.

A primary object of the invention is to provide top or head attaching means for a container such as that used for paint and the like by means of which the cover may be secured in closing relation to the container and which when removed permits the top of head to fit on the pail for the purpose of keeping the contents free from air.

In carrying out these objects, the invention is susceptible of a wide range of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention; there 2 being shown in the drawing for illustrative purposes a preferred and practical form, in which:

Figure 1 is a perspective view of the upper portion of a pail equipped with this improvement;

Fig. 2 is a top plan view; and

Fig. 3 is a detail sectional view.

In the accompanying drawing a pail 1 is shown having a closed bottom and an open top. The body portion of this pail is provided near its upper end with an outwardly extending hollow rib or corrugation 2 and extending circumferentially therearound. Above the corrugation 2 the upper end of the pail is formed with an outwardly extending curved flange 3 having its lower edge folded inwardly to form a lip 4.

A sealing gasket 5 is mounted on the curved top portion of the flange 3 which provides a seat for the curved sealing member or flange 7 of the top or head 6 as shown clearly in Fig. 3.

Adapted to be fitted over the down curved flange 7 of the top 6 is an attachingring 10 constructed of resilient metal which enables the ring to be cammed over the rounded top surface of the flange '7 and to snap under the shoulder s .of the flange 3 when the cover is applied to the pail. It is to be understood that this attaching member 10 is assembled with the cover before the latter is applied to the pail.

A plurality of perforated lugs 12 are integrally formed with the down curved flange 11 of the attaching ring 10. When the cover is applied to the pail these lugs 12 assume the position shown in Fig. 3. Each lug has an aperture 13 and said lugs are designed to coact with a small nail, or other pointed tool which is inserted through the opening in the lug and swung about the crest of the flange 11 as a fulcrum to disengage the inwardly curved edge of the flange 11 from the shoulder 8 of the flange 3 and thereby effect removal of the cover from the pail.

It will thus be seen that when the attaching ring 10 is assembled on the top 6 with the-gasket 5 in position to engage the curved portion of flange 3 the forcing down or camming of the ring 10 over the flange 3 will compress the gasket and hermetically seal the container. This ing 65 ring which takes the place of the ordinary ring seal which latter has to be broken to be removed, is opened by means of the tool as above set forth and without breakage and when the top is taken off the attaching ring 10 may be separated therefrom and the top reinserted to protect the con-- tents of the container.

Without further description it is thought that the features and advantages of the invention will be readily apparent to those skilled in the art, and it will, of course, be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention or its scope as claimed.

I claim:

1. A container body having at its top an outwardly and downwardly curved flange with its edge presenting a shoulder spaced from the container, an outwardly bulged rib formed in said container and positioned adjacent the top thereof, the walls of said rib being at an angle with respect to each other, a top for said container body having a depressed portion to fit into the open top of said container body and having a curved flange overlying the body flange, a gasket 90 between said flanges, a transversely curved sealing ring shaped to fit over said top flange and having an inwardly curved flange engageable beneath the shoulder of the container flange and bent to lie within the space defined by the shoul-. 95 der and container when assembled, said 'ring flange having a plurality of lugs bent to friction ally engage the upper angular portion of said rib and thence extended inwardly, and each of said lugs having an aperture, a wall of which is alined with the lower angular portion of said rib whereby upon insertion of a tool within the aperture for outward bending of said lug, said lower angular portion will function as a fulcrum for said 1% tool.

2. A container body having at its top an outwardly and downwardly curved flange with its edge presenting a shoulder spaced from the con-- tainer, an outwardly bulged rib formed in said no by the shoulder and container when assembled, said ring'fiange having a plurality of lugs bent to frictionally engage the upper portion of said rib for normally holding said flange closely to said shoulder.
