BOTTLE CLOSURE DISK.
Application ined July 3o, i925. serial No. 147,092.
This invention relates to a .closure commonly known as a cap or stopper of the circular disk t-ype for milk analogous liquid containers in which the disk is of slightly greater diameter than the opening in the mouth of the bottle so that when forced into the opening it will be automatically held in place by frictional engagement of its periphery with the walls of said opening.
These disks are usually made of sti' paper or equivalent comparatively inexpensive material treated with paraiiine or similar substance toy render it impervious to moisture and the main object of the present invention is to provide a disk of this character with means whereby a peripheral por- -tion thereof may be opened circumferentially or spil-ally in such manner as to permit the discharge of the liquid from the container through the opening without displacing the remaining portions of the closure from the mouth of the container and at the same time to allow the mo-vable portion to be closed after each opening-to protect the contents of the container from dust and other foreign matter.
One of the specific objects is to score the disk along inwardly convergent lines from the periphery in such manner that the intervening portion may be easily separated along one line from the main body and folded spirally and circumferentially along the other line to form a` corresponding opening for the discharge ofthe liquid therethrough thereby forming what may be termed a closure which will without tions of the bottle.
Other objects and uses relating to specific parts of the device will be brought out in the following description.
In the drawings:
Figures l and 2 are top plans of a bottle closure embodying the various features of my invention with the movable section closed in Figure lv and partially open in Figure 2.
Figure 3 is an edge closure.
Figure 4 is an inverted plan of the same disk.
Figures 5 and 6 are enlarged sectional may be openedand closed at displacing the remaining' porclosure from the mouth of the view of the same bottles and relatively. small supplemental views taken respectively on lines B-B and A' Figure l.
As illustrated, the closure consists of a comparatively thin circular disk -1- of paper card board on equivalent more or less laminated fibrous material of two or more ply coated or impregnated with paraiiine or rsimilar material to render it impervious to moisture, the diameter of the disk being 'slightly larger than the opening inthe mouth of the bottle so that when forced into the opening it will be self-retaining by friction of its periphery with the walls of the opening. c
The opposite faces of the disk are cut at -2- and -2- along offset lines, preferably converging inwardly from the periplr ery toward the center 0f the disk, said cut lines being in this instance radial and at a slight angle to each other so that they may lie in more or less juXta-position but still in offset relation, the disk of each cut being equal to at least half and preferably slightly greater than half the thickness 0f the disk so as to form an intervening connecting web 3- in the plane of cleavage of the layers toA permit the inner and outer halves of the web to be easilyk separated or pried apart by the finger nail or other implement adapted for that purpose.
. The main body of the disk -l-Q is pro-'i vided with a concave recess or depression* -4* in its upper face extendingA laterally from the cut line -2 preferably near the outer end thereof -to permit the entrance of the finger nail to the bottom of the cut line whereby the web -3- may be split along a medial plane thereby forming a radial division or slit from the center to the circumference of the disk and permitting the adjacent portion of said disk at one side of the slit tobe sprung or turned upwardly in a spiral or circumferential direction as shown in Figure 2 and thereby to form an opening 5 through which the contents of the container may be discharged.
In order to facilitate this opening movement of the peripheral portion of the disk at one side of the slit, said disk is provided with an additional radial score 5- eX- tending from the center to the circumference at an acute angle with the cu't lines and. -2- but at a greater angle' than the angle between the thereby forming a. supplemental closure seed rst named "c'it lines tion -1- which is integrally united to the main body along` the score line -5- and is adapted to be deflected upwardly and circumferentially along the score line -5- when the web -3- is split along a medial plane as previously explained to form the discharge opening 5- extending in, wardly trom the periphery o'l the disk.
The score -5- extends only part way through the thickness .et the disk but is ot sullicient depth to render the adjacent portion oi the main Vbody along said line ilexible or beudable to facilitate the .opening of the supplemental closure section -lwhen its opposite edge is detached from the main body.
It is, of course, understood that when the circular .disk .is pressed or forced into the opening in the mouth of the bottle or .other containers the supplemental Closure section -l-- remains integrally united along the cut lines -2`, #-2- and 5* until it is desired to discharge the contents o'l' the bottle at which time the linger nail may be inserted into the recess or depression eiand against the adjacent .edge of the section -lwith suiicient lorce to split the web 3- between the score lines -2- and -2- thereby detaching the adjacent edge of the section -1- from the main body and permitting the entire section -lto be turn-ed upwardly in a spiral or circumferen? tial direction with reference to the circumference oi' the disk to form the opening through which the contents of the container may be discharged.
It the contents are only partially discharged -throngh said opening the remainder may be protected against the entrance of dust or other foreign matter by simply closing the free edge of the section -1- against .the corresponding edge of the main body.
When the web 3 is split along aine `dial plane from one cut line -,2- to the other cut line -2-, the 'free edge of the secton -l.- and adjacent edge ot the main body become rabbeted so that when a section ,-1- is closed its free edge overlaps upon the adjacent .edge of the main Abody, the ledge "wat the rabbeted edge ori the main body consists et a stop for limiting the inward movement of `the free edge ot the section -1- and also ,cooperates .with said free edge to form a closer fitting joint than would be possible it' the cut lines -Q- and -M were in the same plane, it being understood that when the web lis slit in the manner described, the section lmay be opened and closed as oliten as may be desired with the assurance that when closed it will protect the contents ot the bottle against the entrance ot external matter.
It will be observed ,that this disk including the cut lines -Qfand 2- and -5 and also the depression -lma:7 be termed or stamped trom the larger sheets in a s'ngie operation and that aside trom the cut lines -;2, -2- and -5- and depression lithe opposite Ylaces are smooth and parallel and that the entire disk is without entra projections or other removing means and, thereiore, the disks may be stacked liet-wise one upon the other in compact relation and easily displaced one by one by any suitable mechanism when applying them to bottles and that when applied to said bottles th y iorm air and dust tight joints therewith and are impervious to moisture unt-il it is desired to use the contents ol the bottle at which time the seal at the web 3 may be broken to permit the opening ci' the section -lwhen it is desired to discharge the whole or a part ot the contents of the container.
Vlhat I claim is:
A bottle cap comprising ,a circular disk ot paper board having opposite Ylaces thereof cut along different radial lines iii-om the center to the periphery ot and substantially halt' i Yay through the thickness ot the disk at relatively small angle Ato each other, said dsl; being scored along a dillerent radial line 'from the center to the periphery of the `j diskiat a greater angle to `both ct the cut `lines than the angle between said cut lines to allow the portion of the dish between the cuts and score lines to be opened spirally i'roin the periphery inwardly about said score line and thereby to form a triangular opening gradually diminishing in circumterentialfwi lth 'from the periphery to the center .ot the disk.
In witness whereof I have hereunto set my hand this 27th day ,ot' July, 1925.
PHILIP Gr. FRANKLIN.
