BERNARD F. ROEHRIG, OF PASADENA, CALIFORNIA.

JAR SEAL AND METHOD OF APPLYING THE SAME.

Application filed December 14, 1918. Serial No. 266,685.

T 0 all 'aihom it may concern Be it known that I, BERNARD F. RoEHRIc,.

a citizen of the United States, and a resident of the city of Pasadena, county of Los Angeles,.and State of California, have invented certain new and useful Improvements in J arSeals and Methods of Applying the Same, of which the following a specification.

My 'nvention relates to improvements in jar seals and methods of applying the same,

and has for its object the provision of an improved construction and method of this character, whereby jars or other receptacles containing materlal which it is desired to protect from contact with the atmosphere, may be quickly and efiiciently sealed.

Otherobjects will appear hereinafter.

The invention consists in the j ai seal and method of applying the same hereinafter described and claimed.

The invention will be best understood by reference to the accompanyin drawings forming a part of this specifica ion, and in which, v

Fig. 1, is a sectional view illustrating an adhesive supplying pad as used,

Fig. 2, a top plan view of the moisture applying pad, as used, and

Fig. 3, a side view, illustratin a ar in position for effecting the final sea ing, thereof, and alsoi such a jar finally sealed and closed.

The construction illustrated comprises an ordinary jar 4, provided with a removable screw top 5, such as an ordinary glass or porcelain jar for containing cold cream or the like, which has enough consistency to prevent flow thereof. The seal consists of a disc 6 of gelatinous material, such as ordinary gelatine paper, secured over the mouth of the jar and enclosed and protected by the removable cover cap 5, as shown.

The preferred method of applying the sealing disc 6 consists in providing an adhesive supplying pad 7 of felt or similar porous material, said pad being impregnated or saturated with an adhesive, such as a mixture of glue and gelatine, when in aheated state. This pad is arranged in a tray 8, partially filled with water and positioned over a burner 9, whereby the same may be maintained in heated condition. In such condition the adhesive pad 7 will be constantly maintained in a softened and moist condition, in which condition it readily and I quickly serves its purpose. l also provide another pad 10, of felt, which is moistened with water, and on this pad are arranged a plurality of the discs 6, as indicated in Fig. 2, said discs being thus moistened by the water in pad 6 before their application to the jars. Another pad 11, of dry felt, is also provided and arranged in immediate proximity to the pads 7 and 10, when I am ready to proceed with the sealing -opera-, tions. To effect the sealing of a jar, the same is applied to the pad 7, as indicated in Fig. 1, being pressed slightly into said pad and turned so as to apply the adhesive thoroughly to the edges of the mouth of the jar. Then the jar, still in inverted position, is applied at once to one of the moistened discs 6, which will adhere to the edges of the mouth of the jar, whereupon the jar, still in inverted position, is at once applied to the pad 11 and slight downward pressure exerted on said jar, which causes perfect and continuous contact of the sealing disc with the edges of the jar and thus a perfect seal. A closure cap 5 is then applied to the jar, when the sealing and closure thereof is complete.

In this manner and by this means, a perfecthermetic seal may be provided for jars or other receptacles, such as cosmetic receptacles, preserve or jelly jars o-r glasses, and the like. When it is desired to remove the contents, the seal 6 may be broken with the finger or removed with a knife having little or no strength ofv its own. By means of the method set forth, the sealing of jars containing nonflowing material may be readily and quickly effected. While the material in the jar is of a flowing nature, the method outlined above cannot be employed, but it is .obvious that adhesive sealing discs may be readily applied to the jars in upright posi tions. The moisture supplied to the sealing discs by the pad 10 before their application to the jars softens and permits slight stretching of the same in the application, and the drying thereof causes shrinkage which stretches the sealing discs tightly and smoothly over the mouth of the jar and also serves as a test to determine whether or not the adhesion is perfect and continuous.

While I have illustrated and described the preferred form of seal and method of applying the same. these are capable of variation and modification without departing from the spirit of the invention. 1,

, of procedure set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention, whatv I claim as new and desire to secure by Letters Patent is 1. The method of sealing receptacles which consists in providing an adhesive supplying pad; a water moistened pad and a dry pad arranging one or more sealing members on said moistened pad; and applying the edges of the mouth of said'receptacle to said adhesive supplying pad, then to one of said sealing members and then to said dry pad, substantially as described.

2. The method of sealing receptacles which. consists in providing an adhesive supplying pad of felt,- a water moistened pad of felt, and a dry pad of felt; arranging one or more sealing members on said moistened pad; and applying the edges of the mouth of said receptacle to said adhesive supplying pad, then to one of said sealing members and then to said dry pad, substantially as described.

- ,3. The method of sealing receptacles which consists in providing an adhesive supplying heated pad; a water moistened pad and a dry pad; arranging one or more sealing members on said moistened pad; and applying the edges of the mouth of said receptacle to said adhesive supplying pad, t en to one of said sealing members and then to said dry pad, substantially as described.

4. The method of sealing receptacles which consists-in providing an adhesive supplying heated pad of felt, a water moistenedpad of felt, and a dry pad of felt; arranging one or more sealing members on said moistened pad; and applying the edges of the mouth of said receptacle to said adhesive supplying pad, then to one of said sealing members and then to said dry pad, substantially as described. v

5. The method. of sealing receptacles which consists in providing a pad of felt saturated with adhesive material and immersed in a hot water bath, a water moistened pad of felt and a dry pad of felt; arranging a plurality of sealing members on said moistened pad and applying the edges of the mouth of said receptacle to said adhesive supplying pad, then to one of said sealing members and then to said dry pad, substantially as described.

6. The method of sealing receptacles which consists in providing an adhesive supplying pad and a water moistened pad;

arranging one or more sealing members on said moistened pad and applying the edges ofthe mouth of said receptacle to said ad- -which consists in providing a supplying padcontaining hot adhesive and a water molstened pad; arranging one or more members on said moistened pad; applying the edges of the mouth of said receptacle to said adhesive supplying pad',and then to one of said sealing members, substantially asdescribed.

8. The method of sealing receptacles which consists in applying a hotplasticadhesive substance of a congealable material to the edges, of the mouth thereof; and then applying a semi-fusible sealing member containing similar congealed material to said adhesive substance to form a bond therei adhesive containing a particular congealable substance to the edges of the mouth thereof; and then applying a fusible sealing member containin similar congealedsubstance to said adhesive substance to form a bond therewith, substantially as described.

10. The method of sealing receptacles which consists in applying a mixture of hot gelatine and adhesive to the edges of the mouth thereof; and then applying a sealing member coated with congealed gelatin to said mixture to form a bond therewith, substantially as described.

11.-The method of sealing receptacles which consists in applying a hot mixture of adhesive substance containing congealable gelatin to the edges of the mouth thereof; and then applying a congealed gelatine sealing member which forms a bond with said adhesive substance, substantially as de-- stance fused therewith and forming a hermetical closure, substantially as described.

In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.
