J., assigner to Owens-Illinois Glass Company, a corporation of hio Application November 25, 1939, Serial No. 306,105
(Cl. 21S-40) 1 Claim.
The present invention relates to improvements in liners for closures of the type employed in sealing bottles, Jars and like containers, and has for an object, the provision of means for preventing warpage of the liners such as frequently occurs while they are in storage as an integral part of the closures and at other times. l
Liners which are used commercially are formed of cork, cork composition and in some instances are produced from other compositions. which in sheet form, have a strong tendency to warp, this being due to the fact that such materials absorb and release moisture as atmospheric conditions vary. thereby causing alternate shrinkage and expansion of the material. This condition has been found to prevail with every type of cork or cork composition liner that has been available to date.
An object of the present invention is the provision of a liner, or sealing disk which may be formed of cork, cork composition, etc., and retain the advantages incident to the use of such material without the disadvantages arising from warpage or curling of the material. To this end the invention consists simply in forming a number of slits in that surface of the liner which is bonded to the closure. This procedure has proved conclusively to be the solution of the warpage problem and invariably prevents'warpage of the liners and separation thereof from the closures.
Other objects will be in part apparent and in Fig. 4y is a sectional view taken substantially along the line 4 4 of Fig. 3.
Fig. 5 is a plan view of a liner illustrating another method of slitting one face to prevent warpage.
Fig. 6 is a sectional view taken lsubstantially along the line 6 6 of Fig. 5.
My improved liner or sealing disk is illustrated in commotion with a molded bottle cap I0 or closure, including a circular top Il and depending attaching iange l2. 'Ihe preferred form of the liner I3 (Figs. 2, 3, and 4) consists of a disklike sheet I4 of cork, cork composition or other suitable composition and a facing disk I5 which may be formed of tin-foil, oil paper or like material. In this form of the invention, the upper face of the liner which is bonded to the closure by means of an adhesive, is provided with a sexies of parallel slits I6 which may extend approximately half way through the cork disk, the slits opening at their ends through the periphery of said disk. These slits (Fig. 4) separate the inner face of the disk into parallel ribs and evidently provide means for compensating for expansion and construction of the liner as a whole.
of composition material, one ilat face of the` liner being attached to theinterior of the closure, the liner having said one flat face provided with a series oi slits, the ends of which open through the periphery of the liner, said slits being of a depth equal to approximately one-half the thickness of the sheet and a facing sheet attached to `t-he other iiat face of said liner.
