Definitions

  • the present invention relates to retractable spout assemblies for use in dispensing pourable material from a container.
  • the invention also relates to containers equipped with such novel retractable spout assemblies.
  • Retractable spout assemblies are known for application to the neck of bottles in order to facilitate the dispensing of the bottle's contents. Examples of such known retractable spout assemblies are described in my prior U.S. Patent Nos. 6,026,994 and 6,976,610, the contents of which are hereby incorporated by reference.
  • the spout In the case of cans, the spout is typically inserted towards one of the end walls and the pour direction is towards that end wall.
  • legacy machinery is unable to guarantee that the spout mechanism is inserted in any given orientation. If the spout orientation is incorrect then not only is pouring difficult but the air return path back into the can may not work and drainage of fluid from around the spout may not work. The problem does not arise in the case of bottles, which are symmetrical so that one pour direction is as good and handy as any other.
  • the present embodiments may address the shortcomings of the known configurations by providing a spout assembly which can be used with can-type containers as well as bottle-type containers and which include additional features for enhancing pourability of fluids from the container as well as fluid sealing prior to and following use, and providing pour directionality.
  • the housing is configured with an inner tube and an outer tube, the outer tube for mounting on the neck and the inner tube for holding the spout, the tubes arranged such that when fixedly received within the neck of the bottle, compression of the housing by the neck is not transferred from the outer tube to the inner tube, thereby to allow free movement of the spout from the retracted position to the extended position, irrespective of a level of compression of the outer tube by the neck.
  • FIGs. 4 - 6 illustrate a can-type spout assembly according to the present embodiments in side view ( Figure 4), exploded view ( Figure 5) and cross sectional view (Figure 6);
  • FIGs. 7 and 8 are side ( Figure 7) and isometric ( Figure 8) views of a can-type spout assembly of the present embodiments with attached cap covering the spout in a retracted position;
  • FIG. 9 illustrates the cap portion of an embodiment of the spout assembly according to the present embodiments.
  • FIG. 11 is a simplified schematic diagram illustrating an embodiment of the spout assembly with a one-way ball valve.
  • Retractable spout assemblies for use in bottle or can-type containers may include a membrane for sealing the container and holding the spout in a retracted position using mechanical force transmitted using a ring extending from a separately secured cap.
  • the retractable spout is rotatable even in the retracted position when covered by a cap, to achieve an alignment that provides correct pouring.
  • Legacy machinery for positioning the cap is unable to guarantee a specific direction when placing the caps and spout assemblies on the containers.
  • the spout may include a one-way valve and may also be pivotally mounted for tilting.
  • Container spouts capable of extending outward when the container cap is opened are known in the art. Such spouts are described in previously filed applications to the present inventor. While continuing to develop various spout configurations for specific uses, the present inventor has identified several spout features that are beneficial for use with cans and bottles and provide added functionality and advantages when used therewith.
  • Housing 26 is of cylindrical configuration and includes an outer wall 27 surrounding spout 22 and spring 28 and a mounting member 30 externally encompassing wall 27.
  • Mounting member 30 includes a cylindrical flange 32 which is configured with a circular recess 34 capable of receiving an edge of a wall at the opening of a can.
  • spout assembly 20 can include an air return passageway which forms a part of the spout and is movable therewith.
  • Bottom end 29 of spout 22 includes radially projecting flange or flanges 42 which limit the outward movement of spout 22 with respect to a shoulder 43 of housing 26, and also act as a seal to prevent leakage from the container as container contents are dispensed via spout 22.
  • Housing 26 also includes a cage-like structure 50 at a bottom end thereof for keeping the inlets and outlets clear and thus enabling air flowing into the can through conduit 40 to flow in when the contents are poured from can 10.
  • a cage-like structure ensures that air can enter the can from the sides of housing 26 as well as bottom thereby ensuring that an air intake path is not blocked when the can is tilted for pouring in any direction. Since the air return passageway is part of the spout, the air conduit serving as the passageway is very short to allow the spout to retract into the relatively short housing. Air bubbles that enter the housing during pouring must evacuate from the housing as fast as possible, to allow continuous outflow of liquid. A cage structure allows such bubbles to escape from the side and maintain continuous flow.
  • FIGS 2a-b illustrate a spout assembly 60 which utilizes a single use mechanism in the form of a pull tab 61 (numbers identical to those above illustrate similar components).
  • Pull tab 61 includes a membrane 62 which is co-fabricated with housing 26 and a pull ring 64 which is co-formed with membrane 62. Instead of being co-formed the membrane may equally well be attached subsequently. Pulling of pull ring 64 upwards tears membrane 62 away from housing 26 to leave an opening through which spout 22 can extend outward.
  • Membrane 62 may also serve to maintain spout 22 within the housing and compressed against spring 28.
  • Membrane 62 is preferably weakened at the interface with housing 26 so as to facilitate tearing.
  • a capping machine holds the bottle at the neck and pushes what is effectively a two-part cap onto the bottle.
  • the cap may be removed to reveal the membrane, and the membrane provides the two-fold function of showing that the bottle is unused and retains pressure inside.
  • the structure as illustrated holds the bottle from the outside, as opposed to prior art systems that hold on the inside.
  • the membrane is very thin but is required to hold the spout against the mechanical force of the spring.
  • the ring 70 thus reaches down from the cap to the membrane and mechanically holds the membrane in position against the pressure of the spout and the spring and of the gas in the bottle.
  • FIG. 3 is a simplified diagram illustrating a mechanism for tilting a spout according to an embodiment of the present invention.
  • a configuration in which the spout tilts towards the side opposite the air return passageway is advantageous since a user may pour in a direction of the tilt, thereby positioning the air return passageway following extension provides an advantage.
  • Such a configuration positions the air return passageway opposite the pouring direction and above the largest air space in the container.
  • One approach for enabling directional spout tilting following spout extension is shown in Figure 3.
  • the spout assemblies of the present embodiments may include a spring for urging the spout outward when the cap and/or tab are removed.
  • a spring may be positioned under the spout and as such may be placed in the flow path of the liquid.
  • the spout assemblies of the present embodiments may also be designed so that the spring is not in the flow path of the liquid. That is to say the spring may be positioned around the external surface of the spout, thus maintaining the flow path clear of the spring. The clear flow path may thus facilitate use with non refillable systems and incorporation of a one way valve into the spout.
  • the spout may include an external flange or lip for containing the top end of the spring. The bottom end of the spring may be seated against the top of the housing.
  • can-type containers typically include a circular opening through the top wall of the container. Since in such containers the walls are fabricated from a thin layer of material such as a metal or polymer, engagement between a spout assembly and the wall requires an annular flange configured for engaging the opening in the thin wall of the can.
  • pouring from cans requires offset spout placement and a large bore spout in order to facilitate air inflow into the container.
  • the spout has a preferred pouring direction but the spout is placed on the can after pouring using legacy machinery that is unable to guarantee the orientation of the spout.
  • FIGS 4-9 illustrate a spout assembly which is referred to herein as spout assembly 110 or assembly 110.
  • Assembly 110 may be used with a can type container which is filled with a pourable material, such as liquid beverage, lubricating oil, a pourable particulate material such as sugar, salt, etc.
  • a pourable material such as liquid beverage, lubricating oil, a pourable particulate material such as sugar, salt, etc.
  • Can-type container e.g. tin can, jerry can
  • end wall In a conventional container, it is necessary to puncture a hole through the end wall in order to dispense the contents of the container.
  • Such containers are typically used with a material which is totally consumed at one time (e.g. car oil), and as such, are not typically re-sealable.
  • Assembly 110 includes a housing 112 which is cylindrical and includes an outer wall 114 defining a lumen 116.
  • a spring 118 (see Figure 6) is disposed within lumen 116 and is trapped between a lock ring 120 and a spout 122.
  • Spout 122 may for example be fabricated from two telescoping spout tubes, a lower spout tube 124 which includes an annular thickening 126 which serves to limit the outward extension of spout tube 124 against lumen 118, and an upper spout tube 128 which is fitted within spout tube 124 and similarly includes an annular thickening 130 for limiting extension thereof against spout tube 124.
  • spring 118 which engages a top portion of spout tube 128, forces spout 118 to extend outward from housing 112 until telescoping spout tubes 124 and 128 extend to a position where thickenings 126 and 130 engage their stop points. Compression of spout 122 inward telescopically retracts tubes 124 and 128 and compresses spring 118.
  • Housing 112 further includes an air passageway 133 which extends through housing 112.
  • Air passageway 133 is preferably fixed with respect to the housing and is displaced (angularly) at a fixed angle of 120-180 degrees from the pouring direction of pouring tip 131.
  • Housing 112 further includes an annular flange 132 which is configured with a circumferential recess 134 capable of receiving an edge of a wall at the opening of a can 135 (shown in Figure 10). Recess 134 can be further sealed against the opening of a can by radial outward force applied to housing 112 and recess 134 via cap 139 described hereinbelow.
  • At least two triangular- shaped wings 137 reinforce the flange 132-housing 112 connection.
  • the circumference of recess 134 is slightly smaller than the opening of the intended can to enable press fitting of assembly 110 within the can manually or via automated assembly.
  • Wall 136 of flange 132 extends upwards to surround a top surface of housing 112 to form a circular gutter 140 around opening 138 of lumen 116.
  • Gutter 140 can function in capturing dripping from spout 122.
  • Assembly 110 may also include a cap 139 which fits within gutter 140 (shown in Figures 7-9).
  • Cap includes several tabs 142 (Figure 9) for engaging respective slots 144 (see Figure 5) in wall 136.
  • Tabs 142 may secure cap 139 to housing 112 and also enable cap 139 to apply a rotational force to housing 112.
  • Cap 139 serves two functions, trapping retracted spout 122 within lumen 116 under the force of spring 118, and enabling rotation of assembly 110 within an opening in a can, so as to align the pour direction to be towards the closest wall of the can.
  • cap 139 includes a handle 146 which can be pulled up to enable rotation of cap 139 and attached housing 112 against an opening in the can.
  • To rotate assembly 110 a user simply flips up handle 146 such that it is perpendicular to cap 139, and rotates it in a clockwise or counterclockwise direction.
  • the opening in a can is off center.
  • a spout fitted to the can may require to be used in a specific orientation of pouring. Since the present assembly 110 can be press fitted into a can opening at any orientation of pouring tip 131, since legacy equipment is unable to guarantee an orientation, a mechanism is provided to enable a user to rotate assembly 110 upon opening such that pouring tip 131 points in the correct direction. Since spout 122 is covered by cap 139, a user cannot initially determine the correct direction. Hence cap 139 may include a marking 150, for example an arrow, to enable the user to rotate assembly 110 until pouring tip 131 points in the right direction.
  • Spout assembly 110 may typically be fitted to a can 135 after filling, or supplied as a container accessory in which case a user can fit spout assembly 110 within an opening in the can.
  • Spout assembly 110 can be fitted to a can without cap 139.
  • Cap 139 can be designed to apply radial outward pressure on housing 112 and specifically recess 134 to further seal housing 112 against the opening of a can when the cap is applied.
  • cap 139 retains spout 122 in its retracted position as shown in Figures 7-8.
  • handle 146 is deployed to rotate assembly 110 to the correct orientation as indicated by marking 150 and cap 139 is removed to allow spout 122 to extend outward under the force of spring 118, thereby permitting dispensing of the container contents via spout 122.
  • cap 139 is pressed against spout 122 to force it to its retracted position within the container and cap 139 is fixed in position against housing 112.
  • the spout assembly 110 described herein may utilize a cap 139 to secure spout 122 in a retracted position within housing 112 and to seal can 135.
  • cap 139 seals against housing 112
  • use of a cap 139 alone to both seal and secure spout 122 in the retracted position is not enough.
  • the space formed between cap 139 and the opening of spout 122 may be filled with fluid during shipping and handling of the container although this space is sealed by cap 39. In some cases, additional sealing is required, for example to maintain pressurized gas inside the container.
  • housing 112 can be covered by a single use membrane (enclosing cap 139) which can be pulled off or ripped prior to use.
  • the spout assembly of the present embodiments may also be designed such that spring 118 is not in the flow path of the liquid. That is to say the spring is not positioned around the external surface of the spout, thus maintaining the flow path clear of the spring.
  • Such an arrangement may facilitate use with non-refillable systems and allow for incorporation of a one way valve into the spout.
  • the spout preferably includes an external flange or lip for containing the top end of the spring. The bottom end of the spring may be seated against the top of the housing.
  • FIG. 11 shows how, in an additional embodiment, a one-way valve can be built into the mechanism to prevent surreptitious refilling of the container.
  • a ball valve 150 may be provided as the one-way valve to prevent refilling.
  • a ball 152 travels up and down a track or tube 154, blocking the track 154 when lowered. When pouring, the ball 152 reaches upper end 156 of the tube 154, freeing a restriction in the base 158 of the tube. When attempting to refill, the ball falls towards the base 158 of the tube and closes the restriction, thus preventing refill.
  • valves are known with bottles and cans but there is an additional problem if the spout is a jump-type spout in that the spout can be pulled out altogether and bypassed.
  • a solution is to make the neck of either the spout or the bottle thin enough to break.
  • the prior art spout is a two-part spout which unfolds, and is collapsible, so that it is not possible to insert a one-way valve.
  • a jump spout does not fold and therefore can fit the valve in the spout.
