Definitions

  • the present invention relates to child resistant closures for containers having medicinals or other dangerous materials therein and, in particular, to such a container having a bipositional latch which allows adults of limited dexterity to easily open the container in one configuration and which provides a substantial amount of resistance to adolescents in opening the container when in the other configuration.
  • a hinge is provided which allows a closure member for the container to be molded separately from the remainder of the container, yet which prevents easy removal of the closure member from the hinge side when the closure member is closed. This allows a separately molded closure member to be easily mated with the container when the closure member is in an open position thereof.
  • the container include a hinge for connecting the lid to the body of the container that is also difficult for a child to manipulate and, thereby, open the container from the rear thereof.
  • the lid is also a need in the industry for the lid to be able to be removed from the container when in the open configuration thereof such that the lid can be individually molded from the container. This allows one standard size lid to be manufactured for multiple sized containers or vials at a substantial savings in molding expense.
  • such a hinge hold the lid in at least one predetermined open position such that the lid will not flop freely back into a closed position, thereby making manipulation of the vial difficult. It is also desirable to be able to provide covers or shields for both the latch and hinge to further prevent tampering with these structures by children using their teeth. In addition, the region between the container lid and body other than at the latch and hinge is preferably also protected from children prying apart the lid from the body in this region. Finally, it is desirable in some instances to be able to provide a tamper indicating mechanism on the container which indicates that the lid has been previously opened. This is especially true of pharmaceuticals that are sold over the counter in order to alleviate concerns that the drugs therein have been poisoned.
  • the objects of the present invention are: to provide a container having a closure member and a latch for the closure member which is alternatively adjustable to an easy opening configuration or to a child resistant configuration; to provide such a latch that, when in the child resistant configuration thereof, is relatively inaccessible to a child's teeth?
  • the latch mechanism includes a bipositional and resilient tang or tongue with an outward projecting tooth on a distal end thereof and with an opposite end thereof connected to either the container body or the closure member and with the opposite of the container body or closure member including a bar behind which the tooth flexibly passes upon closing of the closure member such that the tooth is resiliently biased to remain in such position until manipulated by a person opening the container; to provide such a latch wherein the person opening the latch must both push radially against the resiliency of the tongue while pulling upwardly on the closure member thereby requiring to open the closure member; to provide such a latch wherein the degree to resistance provided by the latch member to opening is a function of the support provided directly behind the tongue in conjunction with the flexibility of the tongue; to provide such a container having a hinge thereon which allows rotation of the closure member relative to the container body when the closure member is in an open position thereof; to provide such a hinge including a spaced but generally tangentially extending bar-like structure on a first of

  • FIGs. 1 through 21 illustrate a first container in accordance with the present invention, generally designated by the reference numeral 1.
  • the container 1 includes a container body 3, a closure member 4, a hinge mechanism 5 rotatably connecting the closure member 4 to the container body 3 and a latch mechanism 6 for securing the closure member 4 in a closed configuration to the container body 3.
  • the container body 3 of the illustrated embodiment is a vial-like structure having a generally cylindrical side wall 10 and a bottom wall 11 secured to the side wall 10.
  • The includes inwardly projecting beads 12 such that multiple container bodies 3 with the closure members thereof in an open position can be stacked together and such that the beads 12 allow the stacked or nested container bodies 3 to be removed from one another, as the beads 12 function to prevent a vacuum from being formed between adjacent container bodies 3.
  • a vial-like structure has been shown herein as the container body 3, it is foreseen that the container body could be many different structures such as a squeeze tube, liquid dispensing bottles, including pour and squirt liquid dispensers, aerosol cans, blow molded bottles and the like.
  • the container body could essentially be only an attachment ring for mounting on a retention ring of a glass bottle, a mechanical structure having a lid, such as a copy machine or the like.
  • the present invention can be utilized with a wide variety of devices wherein it is advantageous to protect such a device from being easily opened by children and yet wherein it is desirable for adults of limited dexterity to be able to open the device.
  • a first portion 15 of the latch mechanism 6 and a first portion 16 of the hinge mechanism 5 are fixedly attached to the container body 3.
  • a second portion 17 of the latch mechanism 6 and a second portion 18 of the hinge mechanism 5 are attached to the closure member 4.
  • the latch mechanism first portion 15 comprises a radially outwardly projecting carrier 20 and a tang or thereof by a hinge 22.
  • the terms “upper”, “lower”, “front”, “back” and the like refer to the direction provided in the description of the drawings and, in particular, "front” is to the left in Fig. 4.
  • the distal part of the tongue 21 is thicker or wider than the attached part thereof.
  • the distal half of the tongue 21 includes a rectangularly shaped recess 24.
  • the recess 24 opens radially outward when the latch mechanism 6 is in a hard to open configiuration thereof, such as seen in Fig. 7.
  • the tongue 21 also has a back surface 26 which is opposite the recess 24 and which is generally planar.
  • the carrier 20 includes a mating surface 27 which partly abuts against the tongue back surface 26 when the tongue 21 is in the hard to open configuration thereof.
  • the mating surface 27 extends from near the tongue hinge 22 to near the lower edge of the recess 24.
  • the extension of the mating surface 27 is important in determining how easy or how hard the latch mechanism 6 is to open. It is noted that unless the hinge 22 is designed to have limited flexibility, the position of the hinge 32 must be below the top of the mating surface 27 such that the tongue 21 will abut against the surface 27 at full extension of the hinge 22 and provide a backstop for the lower part of the tongue 21, while the tongue upper or distal end 29 is being biased backwards.
  • a relatively small elongate channel 28 On the most outward side of the recess 24 is a relatively small elongate channel 28. Also extending from near the recess 24 to near the distal end 29 of the tongue is a slanted cam surface 30. It is noted that the tongue 21 5 wherein the tongue 21 is rotated on the hinge 22 such tha the back surface 26 does not engage the mating surface 27.
  • the tongue 21 is constructed of a relatively resilient but bendable material if sufficient force is applied thereto.
  • the tongue 21, when in the hard to open configuration thereof, is bendable at the upper end thereof about an upper edge 32 of the mating surface 27. There is a radius or curved surface extending back from the upper edge 32 about which the tongue 21 bends.
  • the degree of the radius and the placement of the edge 32 relative to the recess 24 also regulate the degree of difficulty in opening the latch mechanism 6 when in the hard to open configuration.
  • the latch mechanism 6 becomes harder to open because it is harder than to ben3 the tongue distal end 29 rearward so as to clear the latch mechanism second portion 17 and allow the closure member 4 to be opened.
  • the lower side of the recess 24 has associated therewith a bar-like structure 31 that extends across the front of the tongue.
  • the structure 31 functions as a lower projection and further limits the ease of opening of the latch mechanism 6.
  • the structure 31 prevents a user from simultaneously pushing inward on the tongue 21 and upward on the latch mechanism second portion 17.
  • the structure 31 may be not included if it is desirable to have an easy open latch of this type, such as on a lunch box.
  • the upper end of the tongue 21 is as a fulcrum for such bending.
  • the mating surface 27 cooperatively prevents a user from depressing the tongue 21 from beneath the recess 24 such that the user must push against the tongue 21 above the recess 24.
  • this requires at least two manual operations to be applied to open the container 1 in addition to requiring the container 1 to be held, since a user cannot push upward on the closure member 4 with the same finger or thumb being used to depress the tongue 4.
  • the latch mechanism second portion 17 is fixedly secured to the closure member 4 and extends radially outward therefrom.
  • the closure member 4 of the illustrated embodiment comprises a cap or lid 33 having a circumferential side wall 34 and a top 35.
  • a bottom edge 36 of the wall 34 seats in a corresponding recess 38 in the top of the container body 3.
  • the recess 38 has an outer wall or ridge 39 that extends somewhat above the bottom of the closure member 4 when in the closed configuration thereof so as to prevent a child from placing his or her teeth under the closure member 4 and prying it upward.
  • This feature could also be provided by providing a reverse draft or a bead and groove mating between the surface of the container body 3 and closure member 4.
  • the latch mechanism second portion 17 comprises a wedge or tetrahedral-shaped projection 40 extending outwardly from the closure member 4.
  • the projection 40 has an aperture 41 extending from top to bottom therethrough (when in the closed position) and defining an opening for receiving the tongue 21.
  • a bar 43 forms the radially opposite triangularly shaped sections 44 and 45 of the projection 40.
  • the aperture 41 is sufficiently wide to receive the distal end of the tongue 21.
  • the cam surface 30 of the tongue 21 defining a tooth-like structure engages the lower side of the bar 43, thereby pushing the distal end of the tongue 21 inwardly and bending same backwards over the mating surface 27 until the recess 24 clears the bar 43.
  • the distal end of the tongue 21 resiliently springs forward and the recess 24 snugly receives the bar 43 which is essentially shaped identical to the recess 24.
  • the bar 43 thereafter interferingly restricts removal of the tongue 21 from the aperture 41 and, in particular, prevents the tongue distal end 29 from passing through the aperture 41 unless the tongue 21 is bent substantially rearward.
  • the bar-43 includes a radially outward projecting bead 47 which extends past the tongue 21 and recess 24 thereof.
  • the bead 47 provides a fingerhold for a user to urge the closure member 4 upwardly when the opposite hand of the user is being utilized to push the upper end of the tongue 21 backwardly so that the bar 43 is free to clear the recess 24. In this manner, the closure member 4 can be opened.
  • the bar 43 also has a centrally located and upwardly projecting hemisphere or bump 49 thereon which is positioned so as to interferingly mate with the channel 28 of the configuration thereof and when the closure member 4 is in the closed position thereof, such as is shown in Fig. 7 so as to further interfere with opening of the latch mechanism 6 when in the hard to open configuration thereof.
  • the hinge mechanism first portion 16 includes a pair of triangularly shaped and outwardly projecting stubs 51 and 52 joined by a bar 53.
  • the bar 53 has a circular cross-section and is continuous between the stubs 51 and 52.
  • the bar could have other cross-sections including bumps, slots or the like or that the bar could be formed by discontinuous and spaced sections such as nipples extending outwardly from the stubs 51 and 52.
  • the bar 53 is positioned close to the top of the container body 3 and is spaced from the container side wall 10 and aligned such that, if the bar 53 were next to the container side wall 10 that same would be tangential thereto.
  • a stub wall 55 projects outwardly from the side wall 10 toward the bar 53 and in conjunction with the bar 53 56 therebetween.
  • the aperture 56 is sized so as to relatively snugly receive a mating portion of the hinge mechanism 6 as will be discussed below.
  • the hinge member second portion 18 can best be seen in Figs.
  • the hinge member second portion 18 comprises a semi-circular sleeve 58 sized and shaped to be received on and rotate about the bar 53.
  • the sleeve 58 is preferably resilient and has an inner diameter slightly smaller than that of the bar 53 such that the sleeve 58 tightly grips the bar 53.
  • the sleeve 58 is supported by a depending wall 59 extending outwardly and downwardly from the rear of the closure member 4. Extending outwardly from the closure member 4 on either side of the depending wall 59 are also a pair of struts 60 and 61 from which also depend a pair of ears 62 and 63 on the inner sides thereof.
  • the semi-circular sleeve 58 and the ears 63 is defined a centrally located and circular channel 64 sized to be received about the bar 53.
  • a pair of apertures 65 on either side of the sleeve 58 are positioned so as to allow the sleeve 58 to be positioned over the bar 53.
  • the sleeve 58 is somewhat resilient and the apertures 65 are readily biased to a more open position during assembly of this structure such that the bar 53 is forced between the apertures 65 and into the channel 64. It is noted that the configuration and geometry of the structure is such that the bar 53 may be placed in or taken from the channel 64 only when the closure member 4 is in an open configuration thereof.
  • FIG. 19 Shown in Figs. 19 through 21 are various views of the closure member 4 in different states of opening. It is noted that the position of the stubs 51 and 52 is such that the outer and upper edges 66 thereof are positioned so as to selectively engage the struts 60 and 61 respectively of the hinge mechanism s oo .i portion 18, as can be seen in Fig.
  • the edges 66 engage the struts 60 and 61 in such a manner that it requires exertion of a small degree of force on the top of the closure member 4 in order to close the closure member 4 past the position shown in Fig. 21.
  • the closure member 4 is held open until the user desires to close it at which time the user, while holding the contaitrtr 1 L ⁇ one hand, may use a finger of that hand to push downwardly on the closure member 4 thus pushing the edge 66 past the struts 60 and 61 for a "snap- like" closure.
  • Figs. 22 through 24 is a first modified embodiment except in the design of the hinge mechanism 71 thereof.
  • the modified container 70 includes a container body 73 and a closure member 74 connected by th hinge mechanism 71.
  • the hinge mechanism 71 is in some ways similar to the hinge mechanism 5 of the previous embodiment except that a hexagonal shaped bar 76 extends between supporting struts 77 that extend from the container body 73
  • the closure member 74 includes a depending wall 7 with a semi-circular sleeve 80.
  • the interior surface 81 of the sleeve 80 is also hexagonal in shape and similar in siz and configuration to the bar 76 so as to be snugly received thereabout.
  • the sleeve 80 is sufficiently resilient so as to be rotatable about the bar 76 when pressure is applied t the closure member 74, but when the projections of the bar 76 align with the valleys of the sleeve 80, the sleeve 80 tends to hold that position and, therefore, keep the closur member 74 in such a fixed position until such time as pressure is applied again to the closure member 74 by a use to overcome the resistace to turning thereby provided. Illustrated in Figs.

  • the resilient member 100 includes a tooth 101 extending outwardly therefrom. Positioned behind the member 100 is a stub wall 102 with an upper outer radius forcing the member 100. The wall 102 is shaped , and positioned such that the member 100 must be braced to bend back over the wall 102 in order fo the tooth 101 to clear the front of a tab 103.
  • the closure member 91 includes the rectangular tab 103 extendin outwardly therefrom so as to be positioned over the resilient member 100 when the closure member 91 is in a closed position thereof.
  • the tab 103 includes an aperture 104 defining a bar 105 at the outermost side thereof. When in the closed position of the closure member 91, the resilient member 100 is positioned so that the tooth 101 is positioned over the bar 105.
  • FIG. 28 through 30 is a third modified embodiment of a container according to the present inventio and generally designated by the reference numeral 112.
  • the container 112 includes a container body 113 and a lid or closure member 114.
  • the container 112 is similar in many respects to the container 1 of a previously described embodiments will be described in detail rather than repeating many of the common details therebetween.
  • the container 112 includes a latch mechanism 116 and a hinge mechanism 117.
  • the shield 122 functions to prevent children from using their teeth to bite off the top of the latch member 118 and thereby adds an extra degree of child resistance to the container 112.
  • the latch mechanism 116 of the present embodiment also differs from the previou embodiment in that the bar 120 is effectively flush with th most radially exterior surface of the latch member 118 when the latch member II? is in the hard to open position thereof. Effectively, this means that the bar 120 is not accessible to a user to pry the closure member 114 upwardly when the latch member 118 is pushed back sufficiently far for the recess 119 to clear the bar 120. Consequently, shoulders or ears 124 and 125 are provided on t i closure member 114 that allow gripping by the user for prying the released from the bar 120.
  • a further modification of the present embodiment over the first embodiment is in the hinge mechanism 117.
  • the hinge mechanism 117 of the present embodiment is otherwise similar to the hinge mechanism of the first embodiment except that a. shield 127 is provided to extend over the rearward portion of the hinge mechanism 117.
  • the shield 127 provides a smooth exterior surface to a child trying to use their teeth to .damage the hinge mechanism 117 and there y .ine the container 112. This provides a further degree of child resistance to the container 112.
  • Figs. 31 and 32 illustrate a fourth modified container of the present invention generally designated by the reference numeral 130.
  • the container 130 includes a body 131 and a closure member 132 which are connected together by latch mechanism 133.
  • the container 130 is quite similar to the container 1 of the first embodiment described except that tamper indicating means such as tamper guard 134 is provided.
  • the latch mechanism includes a resilient member 135 having an upper tooth 136 which is swingable between easy open and easy to close positions once the container 130 is initially open.
  • the closure member 132 has an outwardly extending bar 137 which is manually received by a recess 138 of the resilient member 135.
  • the tamper guard 134 is an enclosure which is shaped to fit about the distal portion of the resilient member 135 and, in particular, the tooth 136.
  • the tamper guard 134 is frangibly connected to the closure member 132 such that it may be removed by a user tamper guard 134, the container 130 cannot be opened as the tamper guard 134 interferes with the user's ability to push the tooth 136 backwardly so as to clear the bar 137. Once the tamper guard 134 is broken away, the tooth 136 can be pushed by a user so as to clear the bar 137 at which time the closure member 132 can be raised. It is noted that the operation of pushing the resilient member 135 and raising the closure member 132 must be accomplished simultaneously and normally requires the use of both hands. It is to be understood that while certain forms of the present invention have been illustrated and described herein, it is not to be limited to the specific forms or arrangement of parts described and shown.

Abstract

Un récipient (1) est muni d'un élément de fermeture à charnière (4) doté d'un loquet (6) assurant que cet élément est en position de fermeture. Ce loquet existe en deux versions: soit le loquet est conçu "pour résister aux enfants" et il est très difficile pour des adolescents d'ouvrir le récipient (1), soit il est d'une "ouverture facile" et les personnes ayant un tant soit peu d'habileté manuelle ouvriront relativement facilement l'élément d'ouverture (4). Le loquet (6) est doté d'une languette à deux positions (21) fixée par une charnière soit au récipient, soit à l'élément de fermeture. La languette (21) comporte des charnières convenant pour les deux versions et, dans le cas de la version pour adultes, demande pratiquement le recours des deux mains et au degré élevé d'habileté pour actionner l'élément d'ouverture (4). Différents autres mécanismes servent à empêcher les adolescents de manipuler le récipient et à signaler toute manipulation. L'élément de fermeture (4) est rattaché par une charnière au récipient. La charnière comporte un axe (53) fixé soit au récipient (1) soit à l'élément de fermeture (4), et un manchon semi-circulaire (58) qui tourne autour de cet axe (53) et qui est fixé au côté opposé du récipient (1) ou de l'élément de fermeture (4).
