Definitions
- the invention relates to liquid containers and particularly to squeeze-type containers having means to dispense the liquid product when squeezed.
- Applicant's own United States Patent 4,324,249 is believed to represent the most pertinent art.
- This patent discloses a liquid dispenser comprising a squeeze bottle with an opening formed in the underside of the squeeze bottle, a chamber defining an air pocket in an upper portion of the chamber, a liquid passageway connecting a lower portion of the chamber with the interior of the bottle and a liquid outlet connecting the air pocket to the external atmosphere.
- the liquid outlet structure shown in the patent is located at the bottom of or below the squeeze bottle when the latter is oriented with the opening in the squeeze bottle at the underside of the squeeze bottle.
- the squeeze bottle structure of applicant's prior patent is best adapted to liquids of relatively low viscosity.
- a sidewall dispensing device adapted to dispense liquids of relatively high as well as low viscosity.
- United States 3,157,319 to Schwienbacher discloses another bottom dispensing device f6r dispensing an easily dripping liquid.
- the Schwienbacher device comprises a resiliently deformable container with a discharge opening arranged in the bottom of the container, a hood associated with the bottom of the container, with an opening for allowing liquid in the interior of the container to flow past the bottom of the hood into the interior of the hood, and an outlet tube extending from an air space in the hood through the bottom of the container.
- the present invention is based on an appreciation of the fact that, in a liquid container having a structure defining a chamber within the container and an outlet providing communication between an air space in the chamber and the exterior of the container, it is not necessary to provide an outlet at the bottom or beneath the container but that, on the contrary, the outlet can be provided through a sidewall of the container in order to enable the discharge or outflow of the liquid, or in some cases the vapor of the liquid, from the chamber through the sidewall of the container.
- liquid consumer products for example, liquid soap
- a container which can be operated to discharge the product laterally from the container and at a position which can readily be visually observed by the user of the container.
- the air pocket chamber is disposed opposite the bottom wall and is surrounded by liquid.
- a sidewall forms part of the air pocket chamber.
- the air pocket chamber is formed by a tubular structure inserted through an opening in the sidewall.
- Container 20 Protruding outwardly and upwardly through the sidewall 40 and sealed thereto is an outlet passage in the form of a conduit 30 with the inlet end 34 of the outlet conduit 30 serving to enclose and communicate with the upper end of the inner container 32.
- the body of container 20 is substantially sealed apart from the outlet conduit 30.
- Container 20 may be formed entirely of a compressible material or as illustrated in Fig. 1 may be essentially rigid except for a compressible portion 42.
- a cap 44 may be used to close the outer discharge opening 45 of outlet 30 if desired.
- any liquid, whether in the outer container 20 or inner container 32 will not escape or drip from the outlet conduit 30 so long as the container 20 is not compressed or otherwise disturbed and even in the presence of relatively wide variation in the environmental temperature or atmospheric pressure.
- the cap 44 is thus not necessary to prevent escape or dripping of the fluid under normal operation conditions of temperature and atmospheric pressure changes.
- Outlet conduit can be made as large as required to suit the nature and liquid and operating conditions to prevent run-out or dripping.
- the pressure P in the space V-2 above the liquid level must be increased by some suitable means.
- this pressure increase can be achieved merely by squeezing.
- a compressible portion 42 can be compressed to achieve the same effect. No lifting of the bottle is required in either case.
- the volume V-1 between the liquid level 36 and the discharge outlet 45 can be arranged so as to withstand risk of drip, leakage, or the like, and without requiring the use of a cap 44 over the discharge opening 45.
- FIG. 2 A modification of the Fig. 1 embodiment is illustrated in Fig. 2 in which container 50 is formed with a flexible sidewall 52, a cap 54 for filling the container with the desired liquid product 57, an inner container 56 and innerconnected outlet 58 with suitable holes 68 or other openings to allow free transmission between the liquid in outer container 50 and inner container 56.
- Container 50 is furthermore formed in its lower portion with a confining structure 62 so as to provide, in effect, a constricting well around the bottom of inner container 56 to facilitate emptying the product once it is near empty.
- a confining structure 62 so as to provide, in effect, a constricting well around the bottom of inner container 56 to facilitate emptying the product once it is near empty.
- FIG. 3 and 4 Another practical embodiment is diagrammatically illustrated in Figs. 3 and 4 in which there is shown a flexible wall container 70 with a top cap 72 for filling the container and with the internally-formed sloping bottom wall 74 to facilitate final emptying of the contents of container 70.
- Another inner formed vertical wall structure 76 spans the container internally and in conjunction with a suitably formed outer sidewall structure 78 establishes the space V-1 in Fig. 3.
- Wall structure 76 is also placed so as to assist in employing the container particularly when near empty. Openings 80, slots or the like are provided to communicate the liquid 82 in the outer container 70 with the liquid 84 below volume V-1 in Fig. 3.
- a schematically-illustrated, flip-type closure 86 is arranged to pivot on the side of container 70 and when closed and not in use to rest against the wall 78.
- the flip-type closure 86 is raised as in Fig. 3 the outside atmosphere is communicated with the space V-1 in Fig. 3 through channel 88.
- This container is made by locating the flip-type closure 86 in the mold and forming the container 70 around it.
- the level of liquid 84 below space V-1 will rise and as sufficient pressure is applied, the fluid will be discharged through channel 88 in whatever quantity is desired.
- the sloping wall 74 and barrier wall 76 will enhance discharge of essentially all of the contents of the container.
- atmospheric air will be drawn back into the container 70 through channel 88, will bubble through liquid 82, all of which takes place rapidly enabling the user to restore the closure 86 to its nested position.
- Figs. 5-10 are next described all of which are noted as being basically related to a third embodiment of the invention in which the container is designed to be filled with the container in what might be referred to as a vertical position and to be discharged with the container rotated 90 degrees to what can be referred to as a side dispensing position.
- a further characteristic of those forms of the invention illustrated in Figs. 5-10 is that a cap, valve, discharge. conduit and air chamber structure are all designed such that they can be formed as an integral unit separate and apart from the outer container for installation either at the factory of by the consumer.
- the air chamber and discharge structure are formed as part of the conatiner structure and are thus fixed in position at the time of manufacture.
- a flexible wall container 90 during filling utilizes a removable cap- discharge structure 92 such that the liquid 94 can be admitted through the opening 96.
- Structure 92 includes the cap 98 and on this a schematically illustrated flip-type closure 100 which communicates with a tube 102.
- Tube 102 in use, as in Fig. 6 establishes the volume V-1 and communicates with the channel 104 in closure 100.
- Fig. 5 As best seen in Fig.
- the lower intake end of tube 102 is raised a predetermined distance above the sloping wall 106 such that the liquid 94 in container 90 seeks a predetermined level in the space 110 below volume V-1 allowing discharge of the liquid 108 through channel 104 when closure 100 is open and the compressible walls of container 90 are compressed with the sloping wall 106 facilitating emptying of the content.
- a flexible wall container 120 in Figs. 7 and 8 with Fig. 7 representing a filling position and Fig. 8 an operating dispensing position.
- tube 122 forming part of the cap, closure and outlet structure 124 is made flexible and is positioned by means of an internally-formed guide baffle 126. Structure 124 thus can be entirely removed (as illustrated by a somewhat similar embodiment in Fig.
- the container is then brought to the position shown in Fig. 8 adapted for dispensing through the sidewall 144 through channel 142 of closure 140 with the sloping wall 148 facilitating emptying of the contents of container 120.
- Figs. 9 and 10 illustrate a further variation in which the flexible wall container 160 is filled with the liquid contents 162 and the container is sealed by means of the removable cap 164.
- Cap 164 can be a snap-on cap, puncture-type cap, or the like.
- the structure 166 comprising a snap-on cap 168, a schematically illustrated flip-type closure 170, and a discharge outlet tube 172 with the structure 166 being mounted in use as illustrated in Fig. 10 and with the container 160 resting on bottom wall 174 for discharge through sidewall 176.
- the lower end of tube 172 is raised above bottom wall 174 as illustrated in Fig.
- a flexible walled container 200 uses a removable cap 202 for purposes of being filled with liquid 204.
- An inner bell-type container 206 either has its lower open end raised above the bottom wall 208 or as intended to be illustrated in Fig. 11 is provided with suitable openings 210 so as to communicate the liquid 204 in the outer container 200 with the liquid 212 confined in the inner container 206.
- An adjustable outlet tube 220 mounts in a surrounding outlet structure 222 sealed to container 200. Tube 220 can be raised and lowered in the liquid bath 212 within the inner container 206.
- tube 220 In use, positioning of tube 220 effectively controls the level at which liquid enters tube 220 and thus allows the amount of squeeze required on the flexible wall container 200 to be correlated with the position of tube 220. Furthermore, accommodation to temperature variations can be made simply by adjusting the position of tube 220 in or out dependent on whether the temperature is increasing or decreasing. Additionally, by adding graduations on tube 220, as indicated in Fig. 11, container 200 can be designed as.a unit dispensing system for a given pressure change.
- Fig. 12 like Fig. 3, illustrates a construction in which the container 225 is effectively pinched during molding along pinch lines 226, 227 in the manner in which handles are formed on plastic bottles and so as to form the internal air pocket space V-1 utilizing the outer sidewall 230 as part of the air pocket chamber.
- an outlet 235 is formed and which may receive a cap, not shown, in addition to the filling cap 236.
- Fig. 12 thus represents an extremely simple sidewall dispensing construction according to the invention.
- any of the outlet arrangements could be arranged with appropriate orifices so as to induce a spray effect with selected liquids such as perfumes, deodorizers, and the like, if desired.
- the invention containers can also be squeezed when suspended.
- each of the embodiments provides the inner air space V-1 with the level of the liquid below space V-1 being controlled by the partial vacuum V-2 established in all embodiments with the container sealed except for the outlet.
- the sidewall outlet in any of the several forms described can thus be open but nevertheless with appropriate design will not drip or leak in spite of wide variations in temperature so long as the container is not disturbed.
- All embodiments furthermore provide the advantage of inherently guiding any excess fluid back into the space below the volume V-1 whenever the compression is released by the user. Thus, there is in effect a self-cleaning action each time the container is employed.
- a cap is not essential to permit filling of the container. Liquid could be inserted through an opening during manufacture which is then sealed or the container could be filled in an inverted position, or any other position, the opening sealed and the container then righted.
- the discharge structure can be mounted within the container so as to minimize leakage and also the fact that any of the illustrated sidewall discharge arrangements can be substantially varied in size so as to accommodate to either small or wide temperature variations according to the specific design of the practical embodiment utilizing the invention.
- the various embodiments readily lend themselves to being made in a variety of shapes by high production techniques and are adapted to be transported without leakage and over long distances between the point of manufacture and the point of sale and with a range of liquids of varying viscosity.
- the air pocket chambers are formed within the container and are adapted to being formed as relatively thin wall chambers and with minimum use of material.
- thepresent invention provides a liquid dispenser having a container for containing a liquid reservoir and a dispensing chamber within the container, the dispensing chamber having an outlet through the sidewall of the container.
- the present invention provides a liquid dispenser which when operable comprises a container holding a body of liquid surmounted by a first air body at partial vacuum pressure, a re-entrant outlet in a sidewall of the container extending into the container towards the floor thereof, said outlet holding a portion of said liquid body surmounted by a second air body at atmospheric pressure, wherein the container is at least partially resiliently-deformable to enable variation of the partial-vacuum pressure of the first air body whereby to dispense liquid from the outlet.
