Application August 27, 1956, SerialNo. 606,422
4'Cl3imS. (Cl. 222-4215) My invention relates to containers and closure members therefor, and particularly to a container" that'has a closure membery telescopically related thereto.
More specifically, my invention comprises a closure member that is adapted to be applied to a standard container such as a standard glass jar, whichclosure inember is'made of transparent iie'xib'le material so thatitwill slidably engage the body portion o'f the jar or' similar container with a gripping engagement due to the nexibility of the material; The exible material is preferably a'plastic that is of such' a character that it has sufficient resiliency to grip the wall'portion of the container'with which the closure member is associated, the character of the plastic material at present preferred being clear acrylic resin.' Preferably the closure member isV integrally molded, although if found desirable, the body portion and the end w'all thereof may be made of separate pieces' suitably secured together in a well known manner by. adhesive or heating, depending upon thecharacter of the plastic material used.
It is an important purpose of my invention to provide acontai'ner and lclosure member that are sorelated that when'the' closure member is in' one of its .limitingfp'ositions it will hold the closure member in sealingengagement with the container, while, when it is in the other limiting position in which the closure member iseXtended endwise beyond the container, the contents oftheicontainer can be poured or otherwise -passedV into the `extended closure member so that the contents will thus become accessible through a suitable opening provided therefor in the closure member.
The closure member is telescopicallyl related tothe container, which, in its standard form, is open at one end thereof, the closure member having a closed end Wall and a cylindrical side wall that extends from the closed end wall and'h-as an access opening therein that is in the form of a wide gapvextending from adjacent the closed end wall to the open en'd'iof the closure member. It is al purpose'fofmy inventionA toprovide means'gonsaid cylindrical-sidewall that-slidably engages thej cylindrical bodyfportion of thejar orsimilar container, and which isv loca-ted adjacentftheopen vend of the closure member, that grippingly engages-me'lcont-ainer.' Containers of the character with which my closure member is used usually have a' flange' and gasket' l'olding'ne'ans ther"e`n`adja cent the open end thereof and have a convex wall portion at the periphery of the closed end wall where the closed end wall joins the side wall of the container.
The means that grippingly engages the side wall of the container that is on the closure member is of such a character that it is adapted to engage or snap around said convexly curved end wall to hold the gasket that is provided on the gasket holding means on the jar in engagement with the closed end wall of the closure member to seal the container. In order that this ycan be accompl-ished, a new type of sealing means is provided in the form of a gasket that is annular in character and which projects endwise beyond the open end of the jar or' similar container when it is in place so that the com pressible gasket member will engage the closed end wall of the closure member to provide the seal between the closed member andthe container, and the open end of the closure member is provided with resilient means to assure that the gripping means will firmly engage said convex wall portion.
Other objects and advantages of my invention will ap" pearv as the description of the drawings proceeds. I desirel to have it understood, however, that I do not intend to limit myself to the particular details shown or described, except as defined in the claims.
In the drawings:
Fig. 1 is a vertical sectional'view through the container and closure member made in accordance with my invention, in container sealing position.
Fig. 2 is a similar view showing the closure member moved out of closing position.
Fig. 3 is a side elevation ofthe closure memberv partly bro-ken away.
Fig. 4f is a section taken on the line 4 4 of Fig'.` 3.
Fig. 5 is a fragmentary/' longitudinal sectional View through the container and the closure member in an extended position, and
Fig. 6 is a fragmentary section, on an enlarged scale, taken substantially on the line 6 -6 of Fig. 4.
Referring in detail to the drawings, the container to which my invention is applied -is a standard glass jar having the cylindrical `side wall portion 6, a closed end wall 7,l an open mouthS, an annular ilange 9 and gasket retainingmeans 10 adjacent thek mouth or open end 8 thereof. As is customary in containers of this character, lthe end wall 7 has a peripheral convexly curved portion 11, that joins it with the side wall 6.
In carrying outy my invention I provide thecontainer with a compressible annular gasket member 12 adjacent the'mouth 8 thereof, which' is provided with an annular groove thatreceives the retainingmeans 10 and which has inclined wall portions 13 and 14 that are of a conical character and which terminate in an apex or edge portion 15 to thus project the portion 16 of said gasket beyond the end edge 8 of' the container.` Said compressible gasket member 12 also seats against the flange 9, and preferably has an annular lip 26 overlapping the end edge of'the open mouth 8 to provide aseal between said gasket-12 and the container.
My improved closurel member is provided with an end wall l-17 and al sidewallV 18. The side wall 18 is cylindrical-5in; character and joins the end wall 1 7 slightly inwardly from theperipheral edge 19 thereof, to thus provide a narrow ange on the closed end of the closure member.V The cylindrical wallportion 13 extends .only partial-,lyv around the container to which it is applied, havingedge portions 2t) that extendlongitudinally of said sidewwally portion 18 andl are widely spacedvfrom each otherfto provide a wide gap 21 between said edges, whereby an accessopening iseprovided into the c losure memberfwhen it is .extended beyond: the mofuth S of the container, full access thereto being obtained when it is moved to the limiting position extended beyond said mouth 8, as shown in Fig. 5. The end wall 17 and the cylindrical side wall portion 1S are preferably made of a unitary piece of molded plastic material, such as clear acrylic resin, although any clear plastic that is of such a character `that the wall portions 1S can flex outwardly from the position shown in Fig. l to that shown in Fig. 2 can be used. The open end edge of the closure member is provided adjacent thereto with a plurality of inwardly extending projections 22, which are also preferably molded integrally with the wall portion 18. Said projections are preferably located adjacent each of the edges 20 and at a point midway between the edges 20, as shown in Fig. 4, so as to provide a three point engagement of the closure member with the container.
When the parts are in the position shown in Fig. 1 the resiliency of the closure member will cause the projections 2.2. to grip the convex peripheral wall 11 of the end walls 7 and the closure member is of such length that when such engagement between the projections 22 and the convex wal-l portion 11 occurs the gasket member 12 will be compressed between the flange 9 and the end wall i7, and the peripheral edge of the mouth S and said end wall, thus sealing the contents of the container against access of air, moisture, or foreign matter thereto. Preferably a spring wire Z7 is mounted in a groove 28 and extends circumferentially of the side wall 18 at its open end edge 29 to guard against spreading of the wall portion 1S and assure that gripping engagement of the projections 22 with the convex end wall portion 11 will be maintained. The spring wire 27 is preferably retained in the groove 23 by applying heat and pressure to the material of the side wall 18 at its peripheral edge 29 to form retaining beads 3l) at spaced intervals along said edge.
When the closure member is moved from the position shown in Fig. 1 into a position such that the projections 22 engage the cylindrical wall portion 6 of the container, the wall portion 18 will 'oe sprung slightly outwardly, as shown in Fig. 2, and this outwardly sprung position of the wall portion 13 will continue until the projections 22 pass along the wall portion 23 of the container, whereupon the projections will seat in the annular recess 24 adjacent the ilange 9, as shown in Fig. 5.
One of the uses of the container is illustrated in Fig. 5, in which various objects 25 stored in the container have been allowed to roll or flow outwardly into the extended closure member so that these can be reached through the access opening 21 and a desired article removed therefrom. While fastening elements are shown as being the contents of the container in Fig. 5, any suitable small parts, or any suitable loose, or even uid material, can be stored in the container and can be made accessible by extending the closure member endwise, as shown in Fig. 5, and sealed within the container against leakage by moving the closure member to the sealing position shown in Fig. 1. The closure member can be moved between the position shown in Fig. 1 and that shown in Fig. 5, and vice versa, by merely pushing on the ange 19 or the end wall 17 with the fingers of the hand in which the container and closure member are being held, thus leaving the other hand free to remove material, such as the articles 2S, from the extended closure member, which, when in its extended position, forms a tray-like holding means for the articles that are poured or owed into the same from the container by suitably tilting the container slightly upwardly relative to the closure member with the closure member in its extended position.
What I claim is:
1. The combination with a container having a cylindrical body portion open at one end thereof having a flange and gasket holding means adjacent said open end and an end wall having a convexly curved peripheral portion, of a closure member telescopically related to said container open at one end thereof having a closed end wall and a cylindrical side wall extending from said closed .4 end wall of said closure member, an annular gasket mounted on said gasket holding means and projecting endwise beyond the open end of said container and means on said cylindrical side wall engaging said convexly curved end wall portion to hold said gasket in sealing engagement with the end wall of said closure member, said cylindrical side wall having an access opening therein.
