March 1, 1932. J. E. GUNTER SLIP TOP CONTAINER AND PROCESS THEREFOR Filed May 16, 1927 2 Sheets$heet 2 INVENTOR W' A TTORNE Y Patented Mar. 1, 1932 UNITED STA JAMES E. GUNTER, .OF BALTIMORE, MARYLAND SLIP TOP CONTAINER Ann rRocEss THEREFOR Application filed May 16,
My invention relates to a new and useful slip top container and the process of closing the same, and it relates particularly to aslip top container in which the edge of the cap is curled tightly against the wall of the con tainer after the cap is appliedv to the container.
The objects of my inventionare to make such a closure that may be easily applied and removed, and that will hold securely after applying and that will form a reasonably tight seal after once being opened. Another object of my invention is to provide a self contained opener, which also aids in securing the tight hold the cover has upon the container, which will not be in the way of or hinder the efl'ective use of the closing tools.
A further object is the provision of a process for the purposes stated, in which the sealing curl may be tightly curled upon a retaining and an uncurling ring, and by which, upon the uncurling of the sealing curl, the container may be opened without the necessity of the use of pressure upon, or the exposure to the operative of, sharp edges.
Other objects and advantages of the invention will be brought out more fully from the following description and the accompany ing drawings which disclose several preferred embodimentsthereof. v

but not necessarily made of metal.
The container may be of any desired shape,
and it .may be only slightly flared at the mouth, as shown in Figure 6, or it may have an inwardly directed'groove or shoulder on it, as in Figures 1 to 5 inclusive, or it may have an outwardly directed ridge, as in Fig ure 7 or the top of the container may be enlarged, as in Figures 8 and 9. In allthese figures, except Figure 6, a definite shoulder 3 is shown, under which the curled edge 5 on the depending wall 4: on the cap is curled, or

A gasket may be used, as at 11, in Figures 3, 6 and 9.
The container is preferably assembled as shown in Figure'Q, and upon the lower edge of the cap being curled in further, and pressed tightly .upon'or against the container wall, it hugs the container wall tightly, whether there be a shoulder on the wall or not, and' it is quite diificult to remove the cap; When it is desired to remove the cap, the handle of the ring is grasped, and preferably pulled upwardly and outwardly, away from the axis of the container, and thereby the curled edge of the cap is uncurled, and the cap wall is pulled away from the container wall, as shown in Figure 5. The cap may then be readily pushed up with ones thumbs without cutting them and without danger of spilling the contents. The cap may be replaced on the container to keep the contents of the container, and a nearly air tight seal is obtained. Upon once opening the container, it cannot be closed without detecting that opening.
This cap may be applied at the can factory and then the other end would be sealed on by the packer, at his factory.
As many changes might be made in the above arrangements and as many variations may be made without departing from the scope of the invention, it is intended that all features herein described or shown in the accompanying drawings shall be interpreted as illustrative, and that the invention be limited only by the following claims.
I claim 1. The process of closing a container which consists in positioning upon an open end of a container a cap having a wall with an outwardly curled lower edge, providing ,a removable member in said curled edge, re .movably securing said cap in clamping posi tion by further curling said edge tightly around saidremovable member and inwardly and tightlyagainst said container.
2. The process of closing a container which consists in'positi-oning upon an open end of a container a cap having a wall with an outwardly curled lower edge, providing a'removable member in said curled edge with a projecting handle, removably securing said cap in clamping position by further curling said edge tightly around said removable member and inwardly and tightly against said container.
3. The process of closing container which consists in positioning upon an open end of a container a cap having a wall with an outwardly curled lower edge, providing in said curled edge a removable member with ahandle projecting from between said curled edge and cap wall, andbeing thinned where it projects, removably securing said cap in clamping position by further curling said edge tightly around said removable member and inwardly and tightly against said container.
4. In combination, a container, a cap thereon having a depending wall with an outward ly curled lower edge surrounding one end of the container, said curled edge being adapted to be forced inwardly and tightly .against the'container wall, and means to'positively uncurl said curl, and thereby to loosen said cap upon the container.
5;" In combination, a container, a cap thereon having a depending wall with an outwardly curled lower edge surrounding one end of the container, said curled edgebeing adapted to be forced inwardly and tightly against the container wall and means in said curled edge to positively uncurl the same.
6. In combination, a container, a cap thereon having-a depending wall with an outwardly curled continuous lower edge surrounding one end of the container, said curled edge being adapted to be forced inwardly and tightly against the container wall and a ring in said curl with a projecting handle.

In combination, a container, a cap thereon having a depending wall with an outwardly curled continuous lower edge surrounding one end of the container, said curled edge being adapted to be forced inwardly and tightly against the container wall and a ring in said curl with a projecting handle, said projecting handle being thinned where it projects from said curl.
-8; In combination, acontainer, a cap thereon having a depending wall with an outwardly curled lower edge surrounding one end of the container, a removable ring in said curl with a projecting handle whereby to remove said ring said curled edge being adapted to be curledtightly upon said ring and at thesame time to be forced inwardly and tightly against the container wall.
9. In combination, a container, a cap thereon having a depending wall with an outwardly curled lower edge, a ring in said curled edge, said curled edge and ring tightly surrounding said container and thereby holding said cap upon the container, said ring being adapted to be removed from said curled edge and thereby to partially positively uncurl said curled edge.
10. In combination, a container, a cap thereon having a depending wall with an outwardly curled lower edge,-a ring in said curled edge having a handle projecting from said curled edge. said curled edge and ring tightly surrounding said container and thereby holding said cap upon the container, said ring being adapted to be removed from said curled edge and thereby to partially positively uncurl said curled edge.
11. In combination, a container, a cap thereon having a depending wall with a continuous outwardly curled lower edge, a ring in said curled edge having a handle projecting from the curled edge, said handle having a thinned section where it projects, whereby the curling of said edge is not obstructed by said handle, said curled edge and ring tightly surrounding said container and thereby holding said cap upon the container, said ring being adapted to be removed from said curled edge and thereby to partially uncurl said curled edge.
12. In combination, a container, a cap thereon having a depending wall with an outwardly curled lower edge surrounding one end of the container, a ring in said curled edge, said curled edge being adapted to be curled tightly upon said ring and inwardly and tightly against the container Wall, said ring being adapted to be removed from said curled edge and upon its removalto partially positively uncurl the same.
13. A slip cap container comprising a container and a removable and replaceable cap, the lower edge of said cap being turned outwardly, upwardly and then inwardly to form a bead compressed against the wall of the container and means to pry open said bead and thereby to decrease the hold thereof on the container wall.
