Specication of Letters Iratent.v Patented Sept. 1de, i920.

lapplication led August 28, 1919. Serial No. 320,466.

Be it known that l, DAvro BLooM, a citizen of the United States, and a resident of Berkeley, in the county of Alameda and State of California, have invented a new and Improved Receptacle-Closure, of which the following is a full, clear, and exact description.

This invention relates to a receptacle closure and aims to provide such a device which may be manufactured with a minimum of expense and yet produce an absolutelyairtight closure.

A further object of this invention is the provision of a receptacle closure which may be readily sealed by any one without the practice of any degree of skill, and by means of which the spoiling of the contents of the receptacle will be prevented.

Another object of the invention is the construction of a receptacle closure which, al-

though sealed in such a manner as to be air tight, may be opened instantly.

A still furtherobject of the invention is "the construction of a receptacle closure which, after having once been opened so as to break the air-tight seal provided by such lclosure, is still capable of being used to close the receptacle so it will be almost air tight and so that the closure may be readily used r as a lid for the receptacle.

It is a well appreciated fact that quite a number of receptacle closures lhave been devised which are absolutely air tight, so that any danger of the spoiling of the contents is eliminated. These closures for the most part, however, have proved undesirable, for the reason that it is diiiicult to open the receptacle after the same has once been sealed without the aid of a special instrument.

Further, devices have been constructed which may readily be applied to a receptacle for the purpose of sealingl the same but which have proved ineffective for the reason that an air-tight seal is not produced.

No provision has been made on any of these receptacles for thefurnishing of a liuA with which to close the mouth of the receptacle after the original seal has been removed.

For this reason, as aforestated, l have constructed a receptacle closure which may be readily applied, and once applied will always remain in position Without the slightest danger of the loosening of the seal,

and by means of which an absolutely airtight closure is provided. v

Further, my improved closure may be removed almost instantly without the aid of any special instrument.

Finally, the closure incorporates certain construction by means of which a lid is provided for closing the opened portion of the receptacle so that no danger of dirt entering the same exists. l

Reference is had to the attached sheet of drawings which illustrates one practical embodiment of my inventiomand in which- Figure 1 is a side elevation of areceptacle showing my closure partly in section applied thereto;

Fig. 2 is a sectional side view taken through both receptacle and closure as illustrated in Fig. i;

Fig. 3 is a. view similar to Fig. 2, but showing the adaptability of the closure to function as a lid for thc receptacle after the main seal has been broken;

Fig. 4- is a plan view of the main portion of the closure or seal;

Fig. 5 is a sectional view of a modified form ofclosure or seal; and

Fig. G illustrates my closure as applied to a metal receptacle.

In all these views like reference numerals designate similar parts, and the reference numeral l indicates a receptacle in the form of an ordinary jelly glass which is provided adjacent its upper edge with a bead 2, the outer surface of the portion of the glass between the body l of the receptacle and the bead 2 being preferably roughened, as indicated by the reference numeral 3, for a purpose hereinafter more fully specified.

Associated with the upper and side faces of the bead 2 is a rim, including a horizontally-extending portion 4 and a flange 5 depending at right angles from the firstnamed portion, the flange being adapted to extend downwardly to a point in approximately the same plane as that in which the roughened surface 3 terminates.

A closure, including a disk 6 of any suitable materiahwith which there is preferably associated a pull cord. 7, for a purpose hereinafter specified, has pasted to its underside a circular sheet of material 8 which has qualities which render it impervious to both air and moisture. in this connection it is to be noted that the disk 6 is of slightly less circumference than the inner face of the bead 2, so that when the closure is applied to the upper end of a receptacle a slight space exists between the upper edge of the bead 2 and the edge of the disk 6, for a purpose hereinafter more fully specified..

T he sheet of material 8 is turned downwardly around the bead 2, and the rim, including the horizontally extending portion 4 and depending flange 5, is then. applied over the bead so that the sheet of material S is interposed between such rimk and the bead 2.

#A shoulder 9 is provided along the inner face of the receptacle 1 and slightlybelow the upper edge of the same, for a purpose hereinafter specified, and a sealing compound 10, such as paraflin, is caused to iill in the space between the rim and the outer face of the body 1 and to engage the roughenedvsurface 3, -Wllereby any danger of its becoming loosened is efectually guarded against.

Referring now to the structure illustrated in Figs. l, 2, 3 and 4, it Will be seen that in practice my receptacle closure is used as follows: The receptacle 1 is lled with a mix- 4 ture it is adapted to contain. The closure,

including the disk 6 and sheet of material 8,

i' is then placed over the open end of the receptacle and the rim applied thereto.

The receptacle is now preferably inverted,

so as to cause any air Within the same to risepto the closed end of the receptacle, and the space between the rim and outer surface of the receptacle is filled Withzny suitable material 10 Which serves to. provide an airtight closure at all points between the rim and the receptacle. Upon the receptacle being returned to its original position, it will be seen that the air Within of the same, particularly if such contentsis a preservelike substance,4 will be trapped and a partial vacuum Will be found to exist between the upper surface of the contents and the closure.

rlhe receptacle may now be stored away Without any fear of the spoiling of its contents, but ivhen it is desired to open the saine, it be accomplished by taking a pin, knife, or any suitable instrument, and piercing the sheet 'of material 8 at a point between the bead 2 and the outer edge of the disk 6 andl by running such instrument around the outer edge of the disk to'en'tirevly separate the same and the underlying portion of ma* terial 8 from the'receptacle, so as, to render the contents of the same readily accessible.

as an almost` air-tight seal. to adequately 1 the contents- Will be seen that this may readilyy disk 6 may be,

protect the remainder of the' contents of the*-y receptacle.

Referring now more particularly to the Preferably the upper face ofthe disk is provided with a central depression 11, which will serve as a housingfor the pull cord 7 when the same is laid flush against the upper surface of the disk 6, as in storage. In this connection it is to be noted that the pull cord 7 is shown in the form of a loop and that the same extends through the disk 6A 'and the ends of the same .extend in d1ametrically opposite Adirections between the sheet of material 8 and the under surface of the disk 6. It is to be understood, however, that I might readily substitute any convenient form of pull for the cord illustrated, which I have merely shown for the sake of convenience.

Referring now, finally to the structure illustrated in Fig. 6, it will be seen that this form is merely an adaptation for a metal or paper receptacle, and that a closure, includ-l ing a disk 6 and sheet of material 8v is provided, together with a rim for closing the same, but thatthe provision of a shoulder 9 on the inner face of the receptacle for receiving the disk 6 must necessarily result in the forming of a groove 12 in the outer face of the same', which groove is convenient-ly adapted to insure choring of the sealing medium 10.

Obviously, any number of modifications and substances of material might well be resorted to Without in the least departing from the scope of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
