Description

TECHNICAL FIELD

The present invention relates generally to the field of containers that store and dispense liquids and, more particularly, to a liquid dispenser system.

BACKGROUND OF THE INVENTION

Modern cleaning systems frequently employ a liquid solvent or agent to help remove stains, sanitize spill areas, remove odors, and/or a number of other functions in addition to removing dirt, soil, and/or debris. The liquid agents employed in cleaning often deteriorate when exposed to the atmosphere. However, common, cost-efficient agent dispensers, such as the common spray bottle, for example, do not effectively reduce intermingling with the atmosphere outside the dispenser. And typical systems that sequester a liquid agent from atmospheric contact are relatively costly to produce, fill, and use.
Additionally, typical condiment dispensers suffer from the same shortcomings. For example, common mustard dispensers allow a relatively high degree of atmospheric exposure with each use, hastening the deterioration of the mustard, resulting in unnecessary waste.
Therefore, there is a need for a liquid dispenser system and/or method that addresses at least some of the problems and disadvantages associated with conventional systems and methods.

In the illustrated embodiment, stalk 212 couples to intake pod 214, disposed at the end of stalk 212 distal to head base 202. In the illustrated embodiment, Intake pod 214 includes ports 216, feet 218 and bottom 220. Generally, ports 216 are configured to permit liquid to pass into intake pod 214 (and into stalk 212). Feet 218 are configured as protrusions from the body of intake pod 214, and are generally configured to prevent bottom 220 from flush contact with a surface or bladder. As such, in one embodiment, bottom 220 also includes a port 216 (not visible in the illustrated perspective).
In one embodiment, head assembly 200 is configured according to the following approximate dimensions:


	spray trigger length:	3.00″
	nozzle length:	0.75″
	head base length:	3.50″
	head base height:	3.00″
	head cap height:	0.50″
	stalk diameter:	0.25″
	stalk length:	10.0″
	intake pod diameter:	0.38″
	intake pod height:	0.50″

Accordingly, as shown, in response to mechanical displacement of trigger 206 (by a user, for example), liquid surrounding intake pod 214 is drawn into ports 216, up through stalk 212 and passes out of nozzle 204. One skilled in the art will recognize similarities with conventional spray bottle operation. In one embodiment, head assembly 200 is coupled to a bladder and bottle as described below.
FIG. 3 is a block diagram illustrating a system 300 comprising a bladder and bottle, such as bladder 106 and bottle 108 of FIG. 1, for example. In the illustrated embodiment, system 300 includes a head cap 310. Head cap 310 is an otherwise conventional screw cap and comprises a plurality of threads 312.

Ports 344 allow communication between the atmosphere inside bottle 340 and the atmosphere outside bottle 340. As such, one skilled in the art will understand that a gap 346 will exist between bladder 330 and the inside wall of bottle 340. Gap 346 will decrease as bladder 330 fills with liquid, and will increase as liquid is removed from bladder 330. Ports 344, by allowing open communication with the outside atmosphere, preventing bottle 340 from collapsing under pressure and/or vacuum.
As such, when coupled with a head assembly, such as head assembly 200 of FIG. 2, for example, system 300 provides a sealed bladder to hold liquid. Configured according to the embodiments disclosed herein, the bottle provides some protection for the relatively weaker bladder, without also exposing the liquid in the bladder to open communication with the atmosphere to the same extent as prior art systems.
In one embodiment, system 300 is configured according to the following approximate dimensions:


	seal cap bottom diameter:	1.50″
	seal cap top diameter:	1.00″
	bladder neck diameter:	2.00″

In the embodiment illustrated in FIG. 3, a seal cap couples the bladder to the bottle, and a head cap envelopes the bulk of the seal cap, coupling the head assembly to the bladder/bottle. In and alternate embodiment, the seal cap is configured as a dual screw cap, as illustrated in FIG. 4.
FIG. 4 is a block diagram illustrating a system 300 comprising a bladder and bottle, such as bladder 106 and bottle 108 of FIG. 1, for example. In the illustrated embodiment, system 400 includes a head cap 410. Head cap 410 is an otherwise conventional screw cap and comprises a plurality of threads 412. Head cap 410 also includes an orifice 414. In the illustrated embodiment, orifice 414 is a circular orifice and is configured to correspond to a neck or bladder orifice, described below. Head cap 410 couples to a seal cap 420.
In the illustrated embodiment, seal cap 420 is a dual screw cap, configured with external threads 424 and internal threads 426. External threads 422 couple to threads 412 of head cap 410. Seal cap 420 also includes an orifice 424. In the illustrated embodiment, orifice 424 is a circular orifice and is configured to correspond to orifice 414. Seal cap 420 couples a bladder 430 to a bottle 440.
Bladder 430 is an otherwise conventional bladder and is configured to store liquid. In the illustrated embodiment, bladder 430 is disposed within a bottle 440. Bottle 440 is an otherwise conventional bottle and is configured to receive bladder 430. Bottle 340 includes body 442, neck 444 and ports 450. Generally neck 444 defines an orifice roughly corresponding to orifice 414 and orifice 424. Neck 444 includes external threads 446. External threads 446 couple to internal threads 426.
As illustrated, seal cap 420 is configured to fold and hold an open end of bladder 430 over neck 444, coupling together external threads 446 and internal threads 426, thereby coupling bladder 430 to bottle 440. Ports 450 allow communication between the atmosphere inside bottle 440 and the atmosphere outside bottle 440. Ports 450, by allowing open communication with the outside atmosphere, preventing bottle 440 from collapsing under pressure and/or vacuum.
As such, when coupled with a head assembly, such as head assembly 200 of FIG. 2, for example, system 400 provides a sealed bladder to hold liquid. Configured according to the embodiments disclosed herein, the bottle provides some protection for the relatively weaker bladder, without also exposing the liquid in the bladder to open communication with the atmosphere to the same extent as prior art systems.
FIG. 5 is a block diagram illustrating an alternate embodiment. System 500 includes a bladder 520 disposed within a bottle 530. Bladder 520 is an otherwise conventional bladder, modified as described above. Bottle 530 includes ports 532 and is an otherwise conventional bottle, modified as described above.
In the illustrated embodiment, system 500 includes a modified head assembly. Specifically, system 500 includes pop top cap 502. Pop top cap 502 includes a pop-top closure 504 coupled to a port 506. Pop-top closure 504 is an otherwise conventional pop-top closure, configured to allow liquid to pass through the closure when in a open position, and to restrict liquid flow when in a closed position. Port 506 couples pop top cap 502 to a seal cap 510.
In the illustrated embodiment, seal cap 510 is configured to couple bladder 520 to bottle 530 in a similar fashion as seal cap 320 of FIG. 3. Seal cap 510 includes one-way valve 512. In the illustrated embodiment, one-way valve 512 is a multiple flap valve. One skilled in the art will understand that other one-way valves can also be employed.
In the illustrated embodiment, system 500 does not include a stalk or spray assembly. Instead, pop-top closure 504 functions as a nozzle, and liquid is removed from system 500 though squeezing bottle 530. As such, in one embodiment, bottle 530 is constructed with a semi-rigid material, which allows a general form that protects the bladder 520 from tearing, but allows for some deformation caused by squeezing.
Squeezing bottle 530 puts pressure on bladder 520, which forces liquid through one way valve 512, out pop-top closure 504. System 500 is preferably configured to dispense condiments, soap, or other liquids generally too viscous to dispense through a spray mechanism. Thus, the bladder/bottle combination of system 500 stores liquid with reduced exposure to the outside atmosphere, reducing degradation of the liquid stored in system 500.
Accordingly, the disclosed embodiments provide numerous advantages over other methods and systems. For example, the disclosed embodiments provide a flexible bladder that contains liquid in a dispersal system with reduced exposure to the outside atmosphere. The reduced exposure to the outside atmosphere can extend the useful life of the liquid stored in the bladder, by reducing deterioration.
The disclosed embodiments also allow the bottle to be filled normally, without requiring the bladder to be changed with each refill. The disclosed bladder can also be configured to fit inside standard sized bottles, modified as described above. Further, because the bladder generally contains only liquid, and reduces in size as the liquid is dispensed, the stalk and other pumping mechanisms are always primed, resulting in improved ease of use.
Example liquids suitable for storage and dispensing using the disclosed embodiments include: disinfectant, carpet cleaner, stain cleaner, soybean oil, ketchup, mustard, mayonnaise, salad dressing and other condiments, and other suitable liquids. This list is illustrative only and in no way limiting.
One skilled in the art will appreciate that variations of the above-disclosed and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Additionally, various presently unforeseen or unanticipated alternatives, modifications, variations or improvements therein may be subsequently made by those skilled in the art, which are also intended to be encompassed by the following claims.
