Patented Dec. 15, 1931 PATENT OFFICE navrn 310011,01* BERKELEY, CALIFORNIA CONTAINER Application led" December 3, 1928. Serial No. 323,303.

My invention relates to containers and is especially concerned with containers of the type disclosed in my previous patent, Number 1,459,277 issued June 19, 1923, and en- ,5 titled Closures for containers. In containers of this type, in which a receptacle is provided and is equipped with a closure embedded in a sealing substance such as paraflin, it is sometimes difficult to ensure that the l paraffin will properly embed and secure the closure and receptacle together. And it is also sometimes difficult to remove the closure when it is desired to gain access to the contents of the container.

, I6 It is therefore an lobject of my invention to provide a container in which the sealing material is properly disposed with respect to the receptacle and the closure.

Another object of my invention is to provide means for facilitating the opening of such. containers.`

An additional object is to improve in general containers of this type.

The foregoing and other objects are at tained in the embodiment of the invention shown in thevdrawin s, in which Figure 1 is a plan o a container constructed in accordance with my-invention.

Figure 2 isa transverse section on the line 2-2 of Figure 1. l

' Figure 3 is likewise a transverse section of a portion of my container, the closure being shown in dislodged position.

Figure 4 is a partial side elevation of a slightly modified form of the container of my invention.

constructed of earthenware or glassware.

In its preferred form, the container of my invention, referably includes a shouldered receptacle aving a. mouth provided with. a closure which is embedded in a sealing substance adhering to both sides of the closure as well as to the interior of the receptacle and which is adapted to be dislodged from closed position upon exure of a portion of the edge of the receptacle.

As disclosed in the provide a receptacle 6 having upwardly flaring sides terminating in a mouth 7. yWith upwardly flaring contour.

drawings, bI preferably the type shown in Figure 2, the receptacle is conveniently made of impregnated paper disposed in a suitable form andshaped at its upper end to provide a shoulder 8 having an To provide a closure for the mouth of the receptacle, I p0- sition a disc 9 across the mouth of the container and preferably locate it adjacent the shoulder 8. Thedisc is conveniently made of paper or other similar material and is per- 00' forated, as at 11, well within the confines of the disc. After the substance 12 to be packed has been placed in the container, the closing disc 9 is suitably positioned and a sealing material such as melted paraffin 18 ispoured 65 upon the disc'9 and flows thru the perfora- A tions 11 to embed the disc completely.

In order to provide an outlet for air which might otherwise remain entrapped, in addition to the perforations 1l I preferably ro-l 70 vide perforations 14 on the periphery o the disc so that the disc may be termed notched. These perforations lying at the edge provide an exit for the air within the container and permit the melted sealing substance to adhere not only to the disc but also to the interior walls'of the receptacle. The fact that the walls of the shoulder 8 are upwardly flaring permits the sealing substance to become interposed between them and the disc and 80 precludes the possibility of any air becomino' entrapped therebetween.

In order to afford a convenient means for opening the container after it has once been sealed as described above, Ipreferably mark v the upper edge 15 of the receptacle with Figure 5' shows in cross section a container bounding lines 16 defining limited portions thereof. The marks may be simply imprinted upon the material of the rece tacle or they can be perforations or weakene por- 9 tions. extending partially therethru. Furthermore, I turn the material of the receptacle upon itself to afford. an inturned edge 17 which not only reinforces the mouth of the receptacle but provides what is in effect a lever extending below the closure 9. When I desire to open the sealed container of my invention, I preferabl iex one of the marked portions between the lines 16 either after additionally weakening it by a cut along thel lo lines or, if the perforations are suiiiciently deep, by simply tearing the material along the marks and deforming the upper edge 15 outwardly. This results in the inturned 5 portion 17 moving upwardly against the lower side of the closure 9, and dislod 'ng it from sealed position, as is indicated in igure 3. In this fashion there is provided a very simple and effective way for opening an otherwise tightly sealed container.

"In Figure 4 is disclosed a slight modificaf flaring surface. ubstantially seated upon the shoulder is a closurel disc 28 embedded in a sealing substance 29 such as paraiiin which, due to the coniiguration of the shoulder 27, is easily enabled tol iow between the lower face of the closure 28 and the flaring surface 3o of the shoulder 27 and not only provides a firm bond therebetween but also insures that any air which vmight otherwise be entrapped is totally displaced through marginal perforations 31 in the disc.

35 It is to be understood that I do not limit myself to the form of the container shown and. described herein, as the invention, as set forth in the following claims may be embodied in a plurality of forms. i

I claim:

1. A container comprising a `receptacle having a mouth, a -perforate disc disposed in said mouth, the erforations in said disc being disposed at t e periphery thereof, and a sealirg substance encompassing said disc.

, 2. container comprisin a receptacle having a mouth, a peripheral y notcheddisc forming a closure for said mouth, and a sealing substance embedding said closure.

notched disc having a plurality of perforations therein, and means for confining iexure of said edge to a limited portion thereof to dislodge said closure.

6, A container comprising a receptacle having a mouth, a closure for said mouth, and an inturnededge on said receptacle; said edge being adapted to be fulcrumed adjacent said mouth to serve as a lever for dislodging said closure.

y 7. A container comprising a receptacle having a mouth, a closure seated in said mouth, and an inturned edge on said receptacle partially underlying said closure; said',k

edge being adapted to be fulcrumed adjacent said mouth to dislodge said closure.

. 8. A container comprising a receptacle having a mouth, a closure for said mouth, a sealing substance encompassing said closure, and an .inturned edge on said receptacle; said edge being adapted to be fulcrumed adjacent said mouth to serve as a lever for dislodging said closure.

In testimony whereof, I have hereunto set my hand.
