JAR 0R BOTTLE CLOSURE.

SPECIFICATION forming part of Letters Fatent No. 742,652, dated October 27, 1903.

Application filed May 18, 1903. erial No. 157.640.

To all whom it may concern.-

Be it known that I, JAMES HIRST, a citizen of the United States, residing at Vineland, Cumberland county, New Jersey, have invented certain Improvements in Jar or Bottle Closures, of which the following is a specification.

My invention relates to jar or bottle stoppers; and it consists of an improved form of paper disk stopper or sealing-cap of the character usually employed in connection with milk-bottles for the purpose of making a temporary air and liquid tight closure.

My invention is fully shown in the accompanying drawings, in which- Figure 1 is a sectional view of the improved sealing-cap forming the subject of my invention shown as applied to a bottle. Fig. 2 is a perspective view of the cap 1; and

proximately to the size of a shouldered recess in the inner wall of the bottle-neck. These caps or disks are pressed into place by spitable means and engage the inner wall of the In this position the caps make quite a tight fit, and it is usually a difficult matter to remove the same. Numerous means have been suggested and provided for accomplishing this result. Such means usually comprised the combination with the stopper of an extra element designed to serve as a projection or handle to be grasped by the thumb and finger, whereby the cap might be removed in a comparatively easy manner. Such seals or stopper, however, having the additional element noted are more expensive than their value warrants. Hence the use of the ordinary plain flat disk has not been superseded to any great extent. My invention provides means for removing the cap integral with such cap, which means do not add to the expense of the same and consist in forming a projection within and from the material of which the cap is composed, which projection may be grasped by the thumb and finger to accomplish the removal of the cap.

In the preferred form of structure embody- 7 shown in Fig. Figs. 3, 4, 5, and .6 are views illustrate ing modified structures embodying my inven (No modeld ing my invention, as illustrated in Figs. 1 and 2, 1 represents the main or fiat portion of the disk, fitting the shouldered recess 2 of the bottle 3. Extending above the main flat portion of the cap is a projection 4, preferably disposed in the center of the cap and which may or may not have a contracted neck portion. By grasping this projection with the thumb and finger the disk or cap 1 is contracted toward the center, causing the edges opposite the thumb and finger to leave the shouldered recess, and the cap is thereby rendered readily removable. At the same time the initial compression of the walls of the projection4 will effect more or less compres-- sion of the air between the surface of theliquid in the bottle and the under surface of the cap, and such compression of the air will tend to lift the cap at the center and assist in the removal of the same.

In the modification shown in Figs. 3 and 6 the projection 4 comprises walls of the material which have been brought together or compressed, as shown, and this form provides simply an engaging means for the thumb and finger and affords no compressing efiect upon the air within the bottle.

In Fig. 4=Ihave shown a form of cap or disk in which a bulbous projection 4 is provided with a contracted neck portion 5.

In Fig. 5 I have shown a form of disk in which the projection 4 bunching up the central portion of the material of which the cap or disk is composed.

Having thus described my invention, I

claim and desire to secure by Letters Patcut- 1. As a new article of manufacture, a jar or bottle closure comprising a sealing-disk having an integral projection struck up from the material'of which the disk is composed, said projection being discontinued some distance from the edges of said disk.

2. Asa new article of manufacture, a jar or bottle closure comprising a sealing-disk having an integral projection struck up from the material of which the disk is composed, and confined to the central portion of the disk. I 3. As a new article of manufacture, a jar or bottle closure comprising a sealing-disk having a bulbous projection struck up from the material of which the disk is composed.

is made by simply 4. As a new article of manufacture, a jar or bottle closure comprising a sealing-disk having a fiat portion of circular shape adapted to fit within a recess in the neck of a bottle and having an integral, struck up, bulbous member projecting from the upper surface of the same. v

5. As a new article of manufacture, a jar or bottle closure composed ofan integral member of pasteboard or paper of circular shape adapted to fit within the recess of a bottleneck and having an integral hollow bulbous projection struck up from the surface of the disk, said projection serving as a handle for the finger and thumb in removing said disk. I

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

JAMES HIRST.
