1 Claim.

This invention relates to new and useful improvements in a closure means for containers and more particularly to a closure means wherein a cap is secured to the container for sealin the same by means of a removable sealing band. An object of the invention is to provide a closure cap for a container which is hlngedly attached to the container and wherein the cap is held in sealed engagement with the container by a removable sealing band.

A further object of the invention is to provide a closure cap of the above type wherein the cap at one side thereof is integrally connected to a retaining collar adapted to be permanently secured to the container.

In the drawings:

Figure 1 is a vertical sectional container sealed by the improved closure means;

Figure 2 is a similar view showing the sealing band removed and the closure cap moved to open position on its hinged connection to the retaining collar which is permanently attached to the container.

Figure 3 is a sectional view of the closure caP and retaining collar before it is applied to the container. I

Figure 4 is a view partly in section and partly in side elevation showing the closure band before it is applied to the container.

Figure 5 is a plan view of a portion of the sealing band showing the connected ends.

The container to which the improved closure means is applied may be of any desired construction. It is essential that the container shall have an open mouth which is to be spanned and closed by the closure cap and that said open mouth shall be surrounded by a sealing lip and that the container adjacent the sealing lip shall be provided with a'shoulder under which the lower edge of the sealing band can be spun for holding the closure cap in tight sealed contact with the lip of the container. The container as illustrated is intended to represent a molded container body. The container body is indicated at I. The mouth of the container is indicated at 2. The lip surrounding the mouth is indicated at 3. The shoulder underneath which the sealing band is spun is indicated at 4. These parts may be of any desired shape and construction.

The means for closing the container includes a closure cap and a retaining collar which are hingedly connected together. The collar is intended to be permanently secured to the container and serves as a means whereby the closure cap is hingedly connected to the container. This view through a 2 closure cap and retaining collar are preferably formed from a single metal blank by a drawing operation.

The cap in Figure 3 is indicated at 5 and the retaining collar is indicated at 6. During the drawing operation the blank is provided with a depending skirt 'l and a central depending portion 8. Between the skirt and depending portion is an inverted channel 9 in which the sealing gasket is placed. The skirt is cut or sheared along a line it parallel with the raw edges of the skirt. This shearing line does not extend all the way around the skirt. One end of the shearing line terminates at the point ii and the other at the point i2. This leaves an integral portion i3 connecting the collar and the cap.

The closure cap formed in the manner described and shown in Figure 3 is placed on the container with the sealing gasket in contact with the container lip 25. The lower portion of the retaining collar 6 is spun beneath the shoulder on the container as indicated at it. This permanently attaches the retaining collar to the closure. However, the line of shearing extends almost completely around the skirt; and connecting of the collar to the container does not necessarily tightly seal the container.

The sealing of the container is accomplished by the attaching of a removable sealing band 55. This sealing band is of the usual character. It consist-s of a cylindrical portion i6 with an inturned upper edge portion ii. The ends of the bands are connected by a lug i8 through a slot in a tongue it. This holds the ends of the band in firm contact with each other. After the sealing band has been placed on top of the cap then the lower edge of the band is spun underneath the shoulder on the container as indicated at 20, in Figure 1 of the drawings. This sealing band will draw the closure cap into tight sealing contact with the lip of the container. When it is de-= sired to open the container the tongue i9 and the holding lug iii are lifted and the ends released so that the band can be removed. After the sealing band has been removed then the closure cap 5 can be swung to open position about the hinge i3 which joins the same to the retaining collar 5. The closure can can be returned to closed posi-- tion and will efiectively cover the container so as to protect the contents thereof. This forms a very eflicient closure and reclosure for the container.

It will be noted that the closure cap where the top joins the skirt 1 has a bead formed therein which greatly facilitates the lifting of the cap.

It is obvious that many changes in the details of construction and the shaping of the parts may be made without departing from the spirit of the invention as set forth in the appended claim.

I claim:

Closure for a container body comprising a closure cap including a top portion and 8, depending skirt, said skirt being slit along a line parallel with the lower edge thereof, said slit terminating so that the ends thereof are spaced to form an integral hinge between the upper and lower portions of the skirt, the lower portion of the skirt being adapted to be permanently attached to the container so that the top portion of the closure cap can swing freely on the hinged connection to open and closed positions, a sealing gasket carried by said cap, and an independent split band having the ends thereof detachably joined, said band being shaped so as to overlie said cap at the upper edge thereof and so as to be secured to the container at the lower edge thereof and operating to hold the cap in sealed 6 engagement with the container body.
