Abstract
The invention relates to a liquid spray bottle with manual air pump for spraying an aerosol mist of cooking oil, salad dressing or other liquids. The bottle has a removable base that enables the user to: clean the tubular bottle interior with conventional dishwashing equipment; and to place whole spices and whole garlic cloves within the bottle to infuse flavours into the liquids to be sprayed.
The removable base also serves as a "sacrificial" means to prevent shattering of the internally pressurised bottle when internal pressure is excessively high or when the bottle is accidentally dropped. The removable base with sealing gasket will leak liquid rather than allow internal pressure to exceed the capacity of the bottle. The base will also shatter and leak thereby absorbing impact rather than permitting the bottle to explode. A removable base also eliminates the stability problem caused when the bottom of a blow moulded bottle bulges under pressure since the separate base can be manufactured with any thickness required to maintain a flat configuration independent of the tubular bottle body.

Description
OIL SPRAY PUMP WITH REMOVABLE BASE
TECHNICAL FIELD
The invention relates a liquid spray bottle with removable bottom and manual air pump for spraying an aerosol mist of cooking oil, salad dressing or other liquids.
BACKGROUND OF THE ART
In order to spray liquids in an aerosol form, the prior art includes several types of manually actuated pressurized spray pumps. In many applications, it is preferable to draw in small amounts of liquid by vacuum through a siphon tube into a one-way valued chamber within the pump. A piston reciprocating in the chamber is used to 1o manually compress the liquid and aerosol mist is sprayed in an intermittent series of bursts. By using this type of spray pump the bottle and liquid within the bottle itself is not pressurized but merely serves as a reservoir from which small amounts of liquid are drawn into the pumping chamber. Examples of such spray pumps are shown in U.S. Patent No. 5,947,340 to Arnold et al. and U.S. Patent No.
4,941,595 to Montaner et al.
In some cases however it is preferable to pressurize the container or bottle holding the liquid and achieve a relatively continuous flow of aerosol at higher pressures.
For example, enclosed metal pressurized containers are used for prepackaging and application of spray paint and other aerosols. The bases of these metal containers 2o however is usually convex inwardly to resist the internal pressure and prevent the base of the container from distorting and destabilizing the container on a flat surface.
Recently, plastic bottles have been produced with manually operable pumps which produce a pressurized liquid within the plastic bottle. The bottles can be repeatedly filled and reused. Manual pumps are disposed within the removable cap to pressurize a volume of air above the contained liquid. Liquid is then forced under pressure through a siphon tube to a manually depressed spray nozzle. The advantage of this system is to provide a more continuous reservoir of pressurized liquid for spraying oils or salad dressings in kitchen applications in a reusable, hygienic, and inexpensive form. The flow of aerosol is more reliable and avoids the variation in pressure and orientation caused by manually operated spray pumps associated with non-pressurized bottles.
Difficulties have been encountered however when plastic bottles are used for containing pressurized liquids. The most economical manner of producing a plastic bottle is by blow moulding. In this manufacturing method, the base of the bottle to along with sides and open mouth are produced in a single rapid operation.
When thin walled blow-molded bottles are pressurized however, the internal pressure causes a flat base to distort and bulge outward. As a result, flat bottomed blow moulded bottles are not suitable for internal pressurization since they become unstable on flat surfaces. This problem is commonly addressed by producing 1s outstanding legs on the blow-molded bottle base or by providing separate sleeve at the base into which the bottle is fitted.
When conventional bottles are used for culinary applications such as storing oil or salad dressing, the cleaning of the bottles is extremely difficult and involves labour and manually washing the internal chamber of the bottle with a brush. Since the 20 interior of a bottle is not commonly visible, it is very difficult to determine whether a bottle has been properly cleaned. In addition, washing closed-end bottles in common dishwashers or other mechanized means produce very unsatisfactory results.
The plastic material, which is suitable for blow moulding is very flexible heat 2s sensitive plastic which distorts severely when heated. Placing heat sensitive blow molded bottles in the hot spray of a conventional dishwasher often results in distortion and irreversible damage to a blow moulded body.

When thin walled blow-molded bottles are pressurized however, the internal pressure causes a flat base to distort and bulge outward.

The plastic material, which is suitable for blow moulding is very flexible heat 2s sensitive plastic which distorts severely when heated. Placing heat sensitive blow molded bottles in the hot spray of a conventional dishwasher often results in distortion and irreversible damage to a blow moulded body.
The uncontrolled pumping of air into one-piece blow molded bottles as well presents the risk of over pressurizing the contents and causing the bottles to explode. Excessively high internal pressure or accidental dropping of the bottle when pressurized can cause shattering of glass or brittle plastic bottles if they are used for such an application. As a result therefore, for safety reasons internally pressurized spray bottles are generally constructed of soft deformable blow moulded plastic. For durability and ease of cleaning as well as for aesthetic reasons it may be preferable to construct such pressurized bottles from harder more heat durable plastics. Due to the risk of injury from exploding or shattering the bottles, to these materials have not been commonly used for pressurized bottles especially where they are subjected to uncontrolled use and abuse in kitchens, restaurants or households.
It is an object of the invention to produce an internally pressurized aerosol spray bottle that can be easily cleaned using conventional dishwashing equipment.
It is a further object of the invention to produce an internally pressurized liquid spray bottle that can be safely used by unskilled consumers and in high traffic kitchen areas without the risk of shattering and personal injury when excessively high internal pressure is present or when the bottle is accidentally dropped.
It is also an object of the invention to enable use of more attractive, durable and 2o higher strength plastics in producing liquid spray bottles to improve performance and avoid the stability problem caused when blow moulded bottles are subjected to internal pressure and bulge at their bases.
Further objects of the invention will be apparent from review of the disclosure and description of the invention below.

BRIEF DESCRIPTION OF THE DRAWINGS
In order that the invention may be readily understood, one preferred embodiment of the invention will be described by way of example, with reference to the accompanying drawings wherein:
Figure 1 shows an exploded perspective view of the tubular bottle body with open bottom and removable base.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Figure 1 illustrates a preferred embodiment of a liquid spray bottle having a tubular body 1 with an open top mouth 2 and an open bottom 3. In the embodiment 1o illustrated the open top 2 and open bottom 3 each include external threads to co-act with mating threads in the cap 4 and base 5 to contain the internal pressure.
The base 5 includes a flexible gasket 6 to resiliently seal the bottom 3 edge of the tubular body 1. The removable cap 4 includes an integral spray nozzle 7, which is provided with liquid under pressure through a liquid siphon tube 8.
After the base 5 has been secured to the tubular body 1, the bottle is partially filled with liquid such as oil which is to be produced in an aerosol. The siphon tube followed by the pump chamber 9 is secured to the mouth 2 by screwing on the cap 4.
In the embodiment illustrated a piston 10 with a sliding seal 11 on the inserted end 2o is inserted into the elongate annular pump chamber 9. Air is manually pressurized within the pump chamber 9 by applying downward pressure to the dome 12. A
one-way flapper valve (not shown) under the nozzle 7 opens inwardly to permit pressurized air to pass from the pump chamber 9 through the flapper valve and enter the interior of the tubular body 1 through the central bore 13. Withdrawal of the piston 10 upwardly causes the flapper valve to close and a slit 14 between the piston 10 and the seal 11 to open thereby allowing air to pass from the atmosphere and refill the pump chamber 1. Reciprocal movement of the piston 10 and opening and closing of the slit 14 and flapper valve (not shown) under the nozzle 7, incrementally pressurizes the air volume above the volume of liquid within the interior of the bottle body 1.
In the embodiment shown the tubular body 1 is substantially cylindrical with an outer wall of uniform thickness. It will be understood however that the invention is not limited to any particular shape of tubular body 1. The open ended tubular body 1 can be injection molded rather than blow molded. As a result, there is a much greater freedom in choice of the material used and the wall thickness is completely to independent of the base 5 thickness. Since the base 5 is separately manufactured, it preferably has a thickness greater than the body wall thickness in order to eliminate distortion under pressure. In this manner, separately manufacturing the tubular body 1 and base 5 eliminates instability caused by bulging of the basis of blow moulded bottles for example.
The tubular body 1 and base 5 preferably are formed of durable rigid injection moulded plastic. Polycarbonate produces a relatively rigid bottle with an aesthetically pleasing glass-like appearance. Polypropylene however is much less expensive and can be produced in volumes more economically than polycarbonate.
The base 5 is also preferably made of a frangible material in order that the base 5 is 2o sacrificed and fractures or shatters prior to the bottle body 1 when excessive pressure is applied internally or when the bottle is accidentally dropped. If the bottle contains liquid when it is dropped, the base 5 will most likely receive the impact and shatter preferably. The structural resilience of the tubular body 1 is much higher than a relatively open base 5. The lateral sides of the base 5 are more easily broken since they are outwardly exposed and are relatively thin compared to the walls of the tubular body 1 and the base bottom wall. As a result, on experiencing impact or excessive internal pressure the lateral thin walls of the base S will preferably shatter and permit controlled expulsion of the pressurized contents.
In order that the invention may be readily understood, one preferred embodiment of the invention will be described by way of example, with reference to the accompanying drawings wherein:
Figure 1 shows an exploded perspective view of the tubular bottle body with open bottom and removable base.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Figure 1 illustrates a preferred embodiment of a liquid spray bottle having a tubular body 1 with an open top mouth 2 and an open bottom 3. In the embodiment 1o illustrated the open top 2 and open bottom 3 each include external threads to co-act with mating threads in the cap 4 and base 5 to contain the internal pressure.
The base 5 includes a flexible gasket 6 to resiliently seal the bottom 3 edge of the tubular body 1. The removable cap 4 includes an integral spray nozzle 7, which is provided with liquid under pressure through a liquid siphon tube 8.
After the base 5 has been secured to the tubular body 1, the bottle is partially filled with liquid such as oil which is to be produced in an aerosol. The siphon tube followed by the pump chamber 9 is secured to the mouth 2 by screwing on the cap 4.
In the embodiment illustrated a piston 10 with a sliding seal 11 on the inserted end 2o is inserted into the elongate annular pump chamber 9. Air is manually pressurized within the pump chamber 9 by applying downward pressure to the dome 12. A
one-way flapper valve (not shown) under the nozzle 7 opens inwardly to permit pressurized air to pass from the pump chamber 9 through the flapper valve and enter the interior of the tubular body 1 through the central bore 13. Withdrawal of the piston 10 upwardly causes the flapper valve to close and a slit 14 between the piston 10 and the seal 11 to open thereby allowing air to pass from the atmosphere and refill the pump chamber 1. Reciprocal movement of the piston 10 and opening and closing of the slit 14 and flapper valve (not shown) under the nozzle 7, incrementally pressurizes the air volume above the volume of liquid within the interior of the bottle body 1.
In the embodiment shown the tubular body 1 is substantially cylindrical with an outer wall of uniform thickness. It will be understood however that the invention is not limited to any particular shape of tubular body 1. The open ended tubular body 1 can be injection molded rather than blow molded. As a result, there is a much greater freedom in choice of the material used and the wall thickness is completely to independent of the base 5 thickness. Since the base 5 is separately manufactured, it preferably has a thickness greater than the body wall thickness in order to eliminate distortion under pressure. In this manner, separately manufacturing the tubular body 1 and base 5 eliminates instability caused by bulging of the basis of blow moulded bottles for example.
The tubular body 1 and base 5 preferably are formed of durable rigid injection moulded plastic. Polycarbonate produces a relatively rigid bottle with an aesthetically pleasing glass-like appearance. Polypropylene however is much less expensive and can be produced in volumes more economically than polycarbonate.
The base 5 is also preferably made of a frangible material in order that the base 5 is 2o sacrificed and fractures or shatters prior to the bottle body 1 when excessive pressure is applied internally or when the bottle is accidentally dropped. If the bottle contains liquid when it is dropped, the base 5 will most likely receive the impact and shatter preferably. The structural resilience of the tubular body 1 is much higher than a relatively open base 5. The lateral sides of the base 5 are more easily broken since they are outwardly exposed and are relatively thin compared to the walls of the tubular body 1 and the base bottom wall. As a result, on experiencing impact or excessive internal pressure the lateral thin walls of the base S will preferably shatter and permit controlled expulsion of the pressurized contents.
Shattering or cracking of the complete tubular body 1 is avoided along with the risk of personal injury associated.
It will also be apparent that the tubular body 1 when the base 5 has been removed can have significant advantage in simplifying and improving the cleaning of the bottle especially when exposed to water spray flowing through the body 1 within a conventional dishwashing process. The interior of the bottle can be easily inspected to ensure that proper cleaning has occurred.
As well the removable base S enables cooks to produce infused flavours in oils or to decoratively include large ingredients such a whole garlic cloves, hot peppers, bay 1o leaves, pepper corns etc. within the interior of a transparent or translucent bottle.
To avoid plugging of the siphon tube 8 with smaller particles of spices etc, the open bottle bottom can be used to insert packages of prepared spices wrapped in cheese cloth or filter paper. Such alternatives are impractical since a closed bottled with a relatively small mouth is extremely difficult to use inserting large objects through the small mouth and removing the objects afterwards. The open tubular body 1 enables various large ingredients or packages to be immersed in the liquid contents.
Insertion and removal of such large objects is extremely simple with a removable base 5 in contrast to a conventional bottle.
Although the above description and accompanying drawings relate to a specific 2o preferred embodiment as presently contemplated by the inventor, it will be understood that the invention in its broad aspect includes mechanical and functional equivalents of the elements described and illustrated.
