Definitions

  • a combined salt and pepper shaker comprises a container body provided with a central partition, a sliding cap, and a cantilevered body.
  • the sliding cap extends beyond the upper side wall of the container body at one end thereby forming a space therebetween.
  • the free end of a spring extends upwardly and outwardly beyond the upper side wall of the container body and is disposed in the space between the container and the sliding cap. More specifically the apertures associated with one of two compartments are normally unobstructed.
  • the known dispenser permits unobstructed access to one of the compartments of the container. Furthermore, it is not provided any mechanism for preventing, or even inhibiting, the entry of moisture, heat or other contaminants into the container.
  • US-A-2 187 735 discloses a self-closing dispenser according to the prior art portion of Claims 1-3.
  • a container dispenser comprises a body extending upwardly as neck upon which is frictionally fit a flange section. An opening in a breast of the flange section receives a separate nozzle which is joined thereto by a double seam connection.
  • a sliding closure member is disposed over the nozzle.
  • a separate coil spring is interposed in the space between the nozzle and one end of the sliding closure.
  • the sliding closure terminates in a peripheral skirt, the lower edge of which is bent outwardly in a curl.
  • the dispenser is not made out of plastic, nor is disclosed the resilient means as a unitary molding.
  • the container dispenser is characterized by a multiplicity of parts and complexity of assembly. This complexity arises from the fact that the dispenser requires an entire gamut of separate members which have to be assembled together.
  • the known container dispenser is also fatally deficient in its ability to prevent leakage, seepage or entrapment of the contents of the container and to protect the contents from ambient humidity and heat. Air, heat, and moisture may readily enter the container and compromise its contents at the point of frictional retention of flange section on body neck and double seam connection.
  • the curled lower edge is spaced more than a minimal distance above double seam, thus providing an additional point of entry for damaging properties.
  • Each of the points of frictional retention also allows for entrapment of the container contents between the various members, thereby detracting from the longevity and operability of the union of the respective parts.
  • the object of the present invention is to provide a self-closing dispenser without the above deficiencies and showing a real simplicity of its parts.
  • the sealing plate of the dispenser according to the invention may be formed integral with the neck, thereby reducing even further the number of separate elements required.
  • the leaf spring is formed as a unitary plastic member with either the neck, the sealing plate, or the cap of the dispenser, thereby eliminating the cost, the difficult assembly and structural deficiencies associated with a separate member.
  • FIGS. 1-4 depict a container 20 with a cap 22 operatively associated therewith.
  • Cap 22 comprises an upper surface and a depending skirt.
  • Several apertures 24 extend through the upper surface of the cap 22 for discharging or dispensing the contents of the container.
  • Container 20 is executed in plastic, and is substantially rectangular, when viewed in horizontal cross-section. Talcum powder, flour, condiments, or other powdery substances might be stored within the container 20.
  • a first arcuate shoulder 26 is formed at one side of the upper end of the container, and a second, identical shoulder 28 is formed at the opposite side.
  • One side wall 32 projects upwardly above the shoulder 28.
  • a horizontally extending sealing plate 34 as shown in FIGS. 3 and 4, extends across the mouth at the upper end of the neck and seals same.
  • Several apertures 36 extend through plate 34. However, apertures 36 are normally not aligned with apertures 24, as suggested by the dotted lines in FIG. 4, but normally overlie the continuous sections of plate 34.
  • End wall 38 of the neck extends between side walls 30, 32 to complete the neck on one side, and a second end wall (not shown) completes the neck on the opposite end.
  • a resilient, integrally formed leaf spring 46 is molded with the neck, or is otherwise secured thereto. One end of spring 46 extends away from end wall 38 in cantilever fashion, as shown in FIG. 3.
  • a first groove 48 and a second groove 50 are separated by land 52 defined in side wall 30 of the neck, as shown in FIGS. 3-4.
  • grooves 54 and 56, separated by land 58 are defined in side wall 32.
  • Inwardly projecting tongues 60 and 62 in one wall of the skirt of the cap 22 fit into grooves 48, 50, while inwardly projecting tongues 64, 66 in the opposite wall of the skirt of cap 22 fit into grooves 54, 56.
  • the tongues fit securely into the grooves, so that the lower edges of the skirt of the cap are drawn toward shoulders 26, 28 of the container 20, and the underside of cap 22 presses against plate 34 seated on the neck of the container.
  • the self-closing dispenser shown in FIGS. 1-4 functions in the following manner.
  • the container 20 is seated in an upright position, and cap 22 is biased by leaf spring 46 to its closed, sealed position.
  • the apertures 24 in cap 22 are not aligned with the apertures 36 in plate 34 so that the contents of the container cannot be dispensed, nor can moisture readily enter the interior of the container to degrade the contents.
  • the cap presses snugly against plate 34 so that . material cannot be trapped therebetween.
  • FIGS. 5-7 illustrate a first alternative embodiment of the self-closing dispenser.
  • a cap 70 is seated upon the neck 72 of a container 74, only a fragment of the container being shown.
  • Several apertures 76 extend clearly through the cap, and similarly, apertures 78 extend clearly through the plate 80 located at the upper end of the neck.
  • Plate 80 may be a separate member, or plate 80 may be integrally molded with the neck of the container.
  • a leaf spring 82 is integrally molded with the neck of the container, and the spring normally biases the cap 70 to its closed position wherein the apertures 76 and 78 are out of alignment, as shown in FIG. 6, by exerting a force against the skirt of the cap.
  • a first groove 84 is formed on the neck of the container 74, and a second groove 86 is formed parallel thereto.
  • a land 88 separates the two grooves.
  • Tongues 90, 92 project inwardly from the cap and fit snugly into the grooves 84, 86.
  • Land 94 is situated between the tongues, and rides along land 88 on the neck of the container.
  • An identical pattern of grooves and lands is formed on the opposite side of the neck (not shown). The tongues and grooves draw the cap 70 snugly against the sealing plate and force the skirt of the cap to travel parallel to, but spaced from the arcuate shoulders 96, 97 of the container.
  • FIGS. 5 and 6 show the cap 70 in its normal, closed position wherein apertures 76 are positioned over solid or unbroken sections of plate 80 and out of alignment with apertures 78.
  • the contents of container 74 cannot be dispensed or discharged, and moisture cannot enter the container.
  • Spring 82 presses against the skirt of cap 70 to maintain this closed, sealed relationship.
  • the user When the user wishes to dispense some, or all, of the contents of the container, he presses his thumb against the cap with sufficient force to compress and overcome the bias of spring 82 and shift the cap leftward, as shown in FIG. 7.
  • the tongues and grooves defined between the neck 72 of the container and the cap 70 enable the cap to slide relative to shoulders 96, 97 until the apertures 76 and 78 are aligned.
  • the contents of the container can then be discharged by inverting the container, shaking and/or squeezing same.
  • the spring 82 restores the cap to its normal, sealed position.
  • FIGS. 8 and 9 depict another manner of forming the resilient member, such as a plastic cantilevered leaf spring, that biases the cap into its home position atop the container.
  • leaf spring 46 is integrally molded with the neck of the container and plate 34 is molded apart from the neck of the container.
  • leaf spring 82 and disc 80 in the first alternate embodiment of FIGS. 5-7. In both instances, the plate fits within and seals off the upper end of the container.
  • FIGS. 8 and 9 employs a unique sealing plate indicated generally by reference numeral 98.
  • the plate 98 which is a unitary plastic molding, comprises a horizontal plate 100, depending flanges 102, 104, 106, 108, and a leaf spring 110.
  • the flanges are press fit within the opening, or mouth, at the upper end of the neck 112 of the container 114, and the cap 116 fits thereover.
  • At least one aperture 118 extends clear through the cap, and at least one aperture 120 extends through the plate.
  • the spring 110 extends into a cavity defined between the neck of the container and the skirt of the cap to normally bias the cap 116 to a closed position, whereby apertures 118, 120 are out of alignment.
  • a first groove 122 is formed in one wall of neck 112, and a second, identical groove 124 is formed in the opposite wall.
  • a tongue 126 formed on one interior wall of cap 116 fits within groove 122, and a second tongue 128 fits within groove 124. The tongues and grooves draw the cap 116 down toward, but spaced from, shoulders 130, 132 formed at the intersection of the neck and body of container 114.
  • the cap 116 is normally biased by spring 110 into its normal, closed position, as shown in FIG. 8.
  • the cap In response to the application of manual pressure by the user, such as by pressing his thumb against the cap 116, the cap is shifted until apertures 118,120 are in alignment. The container is then inverted and the contents are discharged.
  • the spring 110 Upon releasing the manual pressure, the spring 110 automatically returns the cap to its normal, closed position.
  • FIG. 10 depicts another alternative embodiment of the self-closing dispenser.
  • the preferred embodiment of FIGS. 1-4 and the first alternative embodiment of FIGS. 5-7 utilize a leaf spring molded integrally with the neck of the container
  • the second alternative embodiment of FIGS. 8-9 utilizes a sealing plate with an integrally molded spring
  • the embodiment of FIG. 10 relies upon a pair of leaf springs molded integrally with the cap. More specifically, the cap 148 has a-first leaf spring 150 and a second, oppositely acting leaf spring 152 molded in its interior. The free ends of the resilient springs 150, 152 engage opposite side walls of the neck 154 of the container 156.
  • the springs cooperate to center the cap 148 relative to the container, so that apertures 158 in the cap will normally be out of alignment with the apertures 160 in the plate 162 situated atop the neck of the container.
  • the two springs insure that the cap can be shifted with equal ease by a right-handed person, or a left- handed person, and still, automatically, return to a closed position.
  • FIG. 11 shows, on a greatly enlarged scale, the relationship between an aperture 158 in cap 148 and an aperture 160 in plate 162. The apertures are shown in alignment, and the aperture 160 is larger than the aperture in the cap to facilitate dispensing.

Abstract

Un distributeur à femeture automatique comprend un couvercle (70) ayant des ouvertures (76), un récipient (74) avec un goulot (72), une plaque de fermeture (80) montée sur le goulot, et des ouvertures (78) dans la plaque de fermeture (80). Des éléments élastiques, tels qu'un ressort à lames en plastique (82) ou des tampons spongieux sont intégralement formés avec le couvercle (70) et/ou le goulot (72) du récipient, ou fixés entre ceux-ci. Des languettes (90, 92) et des rainures (84, 86) coopérantes séparées par des intervalles (88, 94) sont définies entre la surface intérieure du couvercle (70) et la surface extérieure du goulot (72) pour adapter étroitement le couvercle (70) contre la plaque de fermeture. Les éléments élastiques empêchent normalement l'alignement des ouvertures du couvercle avec les ouvertures de la plaque de fermeture (80). Les ouvertures (76) sont alignées lorsque l'on exerce une pression manuelle sur le couvercle (70) pour distribuer le contenu du récipient (70). Lorsque la pression manuelle est relâchée, les éléments élastiques déplacent automatiquement les ouvertures (76) hors d'alignement et ferment ainsi le distributeur.
