Definitions

  • a multl-part and dlstortable seal construction employ- 215/52. 220/245 ing a biased center wall and sealing wall arrangement which, upon the application and release of pressure to I 56]
  • This invention relates to containers and container closures in which the closures are formed from distortablc materials of construction. More particularly, the invention concerns distortable, reusable, plastic container closures for open-mouthed containers and further contemplates a closure arrangement that is quickly and easily operable and which assures a reliable hermetic seal.
  • Plastic food storage containers have been available for many years and have generally employed a bowl, cylinder, pitcher or similarly shaped vessel and a separate closure or lid made of a relatively flexible material.
  • the closures have normally been of several types, one of which includes an inverted peripheral groove that is placed upon the top edge or rim of a container wall and is pressed onto or expanded over that edge to form a hermetic seal between the two parts.
  • Another typical closure is the two-position type which may be flexed to either of two fixed positions. In one of these positions, the closure may be easily fitted over the rim or within the open-mouth of a container, and then when flexed to the second position, its peripheral portions are forced into tight locking contact with the rim or inside container wall.
  • closures have been quite satisfactory in operation and construction. It should be noted, however, that each is not wholly satisfactory from a plurality of diversified points of view.
  • the closure having the inverted peripheral groove has had to be stretched over or pressed onto the container rim normally by finger pressure applied at successively adjacent points along the top groove defining wall.
  • This may be a time-consuming and laborious procedure, especially if the closure is as tight fitting as is required to obtain a hermetic seal.
  • stress concentrations are increased to such a degree that stress cracking may result.
  • lids of this type are susceptible to warpage due to the inordinate internal stresses and in this warped condition, placement of the lid on a container is made more difficult and sometimes even impossible.
  • the two-position closure may also require some dexterity if it is to be accurately locked in position.
  • the peripheral edge of the closure must be maintained in close association with the top edge of the container as the top wall of the closure is flexed to its locking position. As might be expected, this, in some instances, necessitates that the closure be simultaneously held at the edges and flexed at the center.
  • toggle-action closures may also require dexterity in their proper assemblage with suitable closures.
  • the toggle action lids include hinged areas that necessarily have been weakened and are therefore more susceptible to failure. These also present numerous molding difficulties which tend to limit the materials of construction from which they may be manufactured. And, of course, like the tightly stretched closure mentioned above, extreme stresses are created in the sealed position and this ac celerates stress cracking of the closure. Further, if a roll-type toggle is employed, it is not uncommon for the seal between the closure and container to be lost if items are placed on top of the closure so that the weight of such items depresses the dome-like central area thereof. It should also be apparent that such closures also have a tendency to turn inside-out, thus requiring that the user reinvert the closure before any further attempt is made to seal the container.
  • the expandible cork-like closures are also deficient in several respects, especially where large openmouthed containers are concerned.
  • the construction of such closures besides employing complicated mechanical manipulative devices also neces sarily decrease the usablevvolume in where they are used because of their bulk.
  • the plug type closures lack versatility and, of course, are somewhat unreliable in their sealing action.
  • This invention provides a sealing closure that is, in all respects, representative of a composite incorporating the good features of those mentioned above, and in addition, is more simple in its mode of operation.
  • the construction more fully described hereinbelow enables the user to apply the closure of this invention to any of several types of containers simply by an application of pressure to the approximate center of the closure main wall.
  • this closure is of a multi-pieced construction and includes a finger operable plunger that is adapted to transmit pressure to the approximate center of the main wall.
  • This new closure further includes several distinctive constructional features which enhance its applicability for use in a food storage capavity as well as in other related fields. Among these is a biased, corrugated, fluted or similar center main wall arrangement that effectively and easily enables the contraction and recovery of the center main wall peripheral. edge to a relaxed or asmolded posiltion. This edge, of course, includes as an integral part a sealing wall portion which functions to produce a sealed relationship between closure and container, thus preserving and physically retaining the contained materials therein.
  • the invention also encompasess variable construction parameters affecting the' efficient operability of such closures: Therefore, the construction described in detail below has'as its principle objectives to minimize both internal stresses within the closure and the force required to properly-assemble a closure and container, while at the same time to maximize the sealing pressure between the closure and container and the lateral contraction of the closure sealing wall portion per unit of applied force.
  • FIG. I is a top view of a closure construction incorporating the concepts of this invention.
  • FIG. 2 is an enlarged cross-section of the closure and a partial cross-section of a pitcher, the closure crosssection being taken along line 2-2 in FIG. 3 and showing the closure in sealing relationship with the container;
  • FIG. 3 is a bottom view of the closure as is depicted in FIG. 1;
  • FIG. 4 is a partial cross-section of a typical closure of this invention and of another container.
  • FIG. 5 is a partial cross-section of a pitcher adapted to accommodate the closure of this invention.
  • the closure member of this invention is composed of a plurality of separate parts which function together in the operation of the closure. These include a radially biased, fluted or corrugated center main wall 14 having a centrally positioned substantially planar area 16 in the center surface wall and an upwardly extended side wall 26; a closure top wall 12 having an integral substantially centered bushing-like guide 13; and a plunger l5.
  • the biased or corrugated areas are composed of a plurality of upstanding tapered ridges 18, more fully described hereinafter, which emanate from the substantially planar area 16 and terminate at the peripheral edge 24 of the center main wall 14.
  • the closure center main wall 14 is preferably formed from a distortable thermoplastic, for example, low density polyethylene; however, high density polyethylene, polypropylene, polyolefin blends or similar materials, even light gage metals may be suitably employed using the inventive concept.
  • a distortable thermoplastic for example, low density polyethylene; however, high density polyethylene, polypropylene, polyolefin blends or similar materials, even light gage metals may be suitably employed using the inventive concept.
  • the open-mouthed containers 20 (FIGS. 2 and 4) with which these closures are primarily intended for use, are also generally formed from the same or similar materials. It should be pointed out, however, that such closures may well be adapted for use with containers of a diversified range of materials such as glass, metal, etc.
  • FIGS. 2 and 4 Upon continued reference to FIGS. 2 and 4, it can be seen that at the peripheral edge 24 of the center main wall, there is an integral upwardly extended side wall 26.
  • the outer portion 28 of wall 26 is adapted for mating engagement with the inner area of the projecting wall 30 which forms the open mouth in container or pitcher 10. This engagement, of course, creates the hermetic seal spoken of and thus produces a highly desirable storage container especially suited for the storage of foodstuffs and/or liquids.
  • closure embodiments include an outwardly protruding bead 32 which extends around the periphery of outer portion 28 of wall 26 which bead presses against the container walls in sealing relationship with them.
  • FIG. 2 further shows a circumferential ledge 34 which is intended to act as a bottom stop member for the closure 10.
  • the ledge is produced by downwardly directed inwardly sloping portion 36 of the pitcher wall 21. This terminates after a relatively short inward progression and the normal inner wall contour is resumed. This ledge tends to assist the user in the proper orientation of the closure on the container; however, as is evident from FIG. 4, containers of other configurations may similarly employ this closure member.
  • this type of closure may be used to chase a diminishing amount of foodstuff or liquid down into the container. This operation would minimize the amount of air trapped in contact with the remaining foodstuff in the container and thereby lengthen the time of preservation of the remaining contents.
  • a small interrupted bead 23 partially extends around the inside of wall 21, adjacent the upper edge 27 of the pitcher.
  • This bead functions as an upper stop or position indicator so that the user may accurately reposition the closure 10 immediately below this bead.
  • the closure will not contact the wall 21 in the area of pour spout 25. Therefore, the closure 10 will remain securely engaged with the pitcher, yet pour spout 25 will be open to the container interior enabling the easy discharge of fluids or the like while the closure is so attached.
  • a tapered venting slot 17 is provided on the inside surface of wall 30 approximately opposite pour spout 25 so that when the closure is positioned in its elevated position, air may be bled into the pitcher at that point.
  • a tapered venting slot 17 is provided on the inside surface of wall 30 approximately opposite pour spout 25 so that when the closure is positioned in its elevated position, air may be bled into the pitcher at that point.
  • sealing will be effected all around the pitcher 20 between protruding bead 32 and wall 21.
  • the locally distortable closure member is contractably and distensibly constructed so that the wall 26 will be displacible with the peripheral edge 24 of biased center main wall 14.
  • the resiliency and elastic memory of the particular materials of construction must be considered and, in particular, the center main wall shape should be carefully constructed to take advantage of the physical characteristics of the materials employed. Therefore, the radially extending biased center main wall 14 which extends between the center portion or substantially planar area 16 to a peripheral terminus 24 is of considerable importance to the invention.
  • the biased center main wall 14 tends to collapse upon itself upon the application of pressure to center portion 16. This collapse substantially uniformly displaces the peripheral terminus 24 inwardly and thus draws the wall 26 inwardly.
  • the biased, corrugated, fluted or plaited center main wall 14 includes, therefore, a plurality of upwardly and outwardly tapered ridges 18.
  • the upper portion 38 of these ridges are angularly directed with respect to planar area 16 and therefore their respective peripheral terminus portions 24 lie plane removed from that of area 16.
  • the bottom portions 40 of these plaits lie in a substantially parallel plane approximate to that of area 16 when the closure is in a relaxed or as-molded condition.
  • even the bottom portions 40 will be at least slightly angularly directed toward the container center; such being the result of oversizing which assures a proper seal between the components.
  • the corrugation height at its peripheral terminus 24, i.e., the point of connection to the integral upwardly extended side wall 26, is such that the uppermost flute portion 38 is approximately opposite or above the protruding head 32.
  • the application of pressure to the centrally positioned substantially planar area 16 will cause sufficient inward lateral displacement of the side wall 26 such that the closure slips easily onto the container.
  • the side wall 26 also includes a plurality of inwardly and upwardly disposed projections 29 which are integrally molded at spaced points around the wall. These projections 29 terminate at points adjacent the upper edge 35 of the wall and below the inwardly directed undercut 37 that is formed at the upper edge.
  • the socket 39 framed by wall 4] projects upwardly from the planar area 16 such that it cooperates with the plunger as is described hercinbelow.
  • the closure top wall 12 includes a conically disposed upper wall 38 in the approximate center of which there is positioned the bushing-like guide 13. This guide extends above the upper wall 38 and is aligned with the socket 39.
  • a peripherally disposed depending skirt 40 is positioned adjacent the outermost periphery of upper wall 38 so as to create a lip 42 around the periphery thereof. This lip then is positioned between the undercut 32 and terminal points of projections 29 and is securely held therebetween by these elements.
  • the plunger 15 is, of course, received in the bushinglike guide 13 for axial movement therein and is further received by the socket 39.
  • the socket further includes a plurality of inwardly extending ribs 44 which pressingly engage the plunger and secure it in the socket and to the center main wall 14.
  • plunger 15 also includes a ledge area 47 intermediate ofits extremities which ledge area is adapted to engage with the undersurface of wall 38 adjacent bushing 13 and to thereby function as a stop to arrest the upward movement of the plunger and center main wall 14.
  • the upper portion of guide 13 also includes a finger-grippable flange 45 above which the plunger is adapted. to protrude.
  • the guide may be gripped between the finger digits below flange 45 while the plunger is depressed with the thumb, creating the axial pressure spoken of.
  • one prime objective of this invention is to. optimize forces for applying closures, sealing pressures and stresses but at the same time, to obtain a maximum of sealing pressure using minimum force and creating minimum stresses. Therefore, analysis of the relationships between the applied axial force (pushdown pressure), the lateral contraction or displacement of the side wall 26, the stresses within the closure, and the sealing pressure becomes significant and a discussion of thee may be found in US. Ser. No. 8,228 and 67,340, filed on Feb. 3, 1970, and Aug. 27, 1970, respectively.
  • a sleeve and plunger might be suitably inserted and retained within the bushinglike guide in such manner as to permit elimination of the socket 39.
  • the plunger might be made integral with the center main wall 14 thereby reducing the number of separate parts included in the construction.
  • the closures of this invention tend to experience a lateral displacement within the conical, corrugated or fluted area 18 as pressure is applied to the planar area 16.
  • the conical corrugated construction accentuates this displacement as the flutes fold upon themselves in an accordion-like fashion. This, then, similarly tends to draw the side wall 26 inwardly, thereby facilitating entry of the central surface wall area 14 into the open-mouth end of the container or pitcher 20.
  • the resilient closure material After insertion and upon release of the applied pressure, the resilient closure material attempts to assume its relaxed orientation and thus expands the side wall 26 against the inner portion of the container wall to hermetically seal the container. To remove the closure, it is only necessary to similarly depress the plunger 15 to remove the closure from the pitcher or container.
  • a center main wall including a biased area radially emanating from a central portion thereof to a pcripheral terminus, said center main wall being adapted for the application of pressure to the ap-' proximate center thereof in such manner that said biased area tends to collapse upon itself and substantially uniformly displace said peripheral terminus until said closure is easily positionable in an open-mouthed container;
  • integral extended sealing means positioned around said peripheral terminus of the center main wall, said sealing means being displaceable in like manner with said peripheral terminus such that at least a portion of said sealing means is closely engageable with and scalable against the walls of anopenmouthed container due to there'siliericy and elastic memory of said closure upon the discontinuance of applied pressure to said center main wall; c.
  • closure top wall interconnected with said integral extended sealing means and said center main wall, said closure top wall further including an integral and substantially centered upstanding bushing-like guide terminating at its upper extremity in a finger grippable flange; and, an axially movable plunger positioned in said guide in such manner asto have a portion thereof exposed above said flange so that pressure applied to the plunger is transmitted to the approximate center of said center main wall.
  • a container and a removable closure member in combination a container and a removable closure member according to claim 1 wherein said container includes a projecting wall construction forming the open mouth thereof and including therein a pouring spout and venting slot approximately opposite one another, said projecting wall construction being so that said removable closure is engageable with and scalable thereagainst below said spout and slot and is engageable and sealable with portions of said wall at positions proximate said spout and slot so that with the removable closure in the latter mentioned positions the container contents may be easily poured therefrom.
