A hand held spray can comprising a fluid chamber containing a first fluid, a pumping lever and an interchangeable capsule containing a second fluid. The capsule is provided in a receptacle in the spray can, the first fluid is pumped from the fluid chamber upon activation of the pumping lever by a user, and the second fluid is released from the capsule upon the same activation of the pumping lever, the first and second fluids mix in a mixing chamber and then the mixed fluids are sprayed out through a nozzle in the spray can.

Description

Spray can with interchangeable capsule
Field of the invention
The invention concerns spray cans for household use, and more specifically, a spray can with interchangeable capsules, as set out by the preamble of claim 1.
Background of the invention
Many products which are used in households today consist mainly of water, with relatively few additives. The additives depends on the utilization of the product, and can be such as soap, detergent and even products for cooking such as vinegar, butter in liquid form, oils, etc.
In order to reduce the cost of transporting products containing for a large part water out to the end customer, and to reduce the physical storage size of everyday household products, the applicant has devised the present invention. The present invention will therefore play a significant role in making a private household more environmentally sustainable.
Summary of the invention
The invention is set forth and characterized in the main claim, while the dependent claims describe other characteristics of the invention.
It is thus provided a hand held spray can comprising a fluid chamber containing a first fluid, a pumping lever and an interchangeable capsule containing a second fluid. The capsule is provided in a receptacle in the spray can, the first fluid is pumped from the fluid chamber upon activation of the pumping lever by a user, and the second fluid is released from the capsule upon the same activation of the pumping lever, the first and second fluids mix in a mixing chamber and then the mixed fluids are sprayed out through a nozzle in the spray can.
In one embodiment the receptacle is rotatably connected to the spray can. Brief description of the drawings
These and other characteristics of the invention will become clear from the following description of preferential forms of embodiment, given as non-restrictive examples, with reference to the attached schematic drawings, wherein:
Figure 1 shows a spray can where a capsule of concentrate is inserted.
Figure 2 shows a spray can with a concentrate container, valves and tubes.
Figure 3 is a schematic drawing of the valves and the mixing chamber.
Detailed description of a preferential embodiment
The following description may use terms such as "horizontal", "vertical", "lateral", "back and forth", "up and down", "upper", "lower", "inner", "outer", "forward", "rear", etc. These terms generally refer to the views and orientations as shown in the drawings and that are associated with a normal use of the invention. The terms are used for the reader's convenience only and shall not be limiting.
Figure 1 shows a hand held spray can 1 with a compartment 2 for containing water, and a receptacle 3 for receiving a separate capsule 4 or ampoule containing a concentrate, preferably a fluid, to be mixed with the water upon performing a pumping action with the lever 5. In figure 1, the sequence of inserting the capsule into the receptacle is shown, from a) to d). In a) the receptacle is in an empty, open, inactive state. In b) and c) a capsule is inserted into the receptacle, and in d) the receptacle with the capsule is rotated around a pivot point 19 into the spray can, upon which the spray can is ready to use. As the capsule 4 in the receptacle 3 is rotated into the spray can 1, a nozzle or equivalent connection means connects to the capsule 4, allowing the concentrate to be transported from the capsule 4 into the spray can 1.
If there is no capsule 4 present in the receptacle 3 when the receptacle is in the closed, active position (i.e. in the state shown in d)), the spray can 1 is still able to spray water or whichever liquid is filled in the main compartment 2. A range of capsules with different content can be utilized. The capsules can for example contain various concentrated liquids, for example dishwasher soap, concentrated detergents for use in a household, products to be used when cooking, etc. The capsules (and the content) can be changed depending on the utilization. When a capsule is not inserted in the spray can, the spray can still be utilized for spraying water or whichever liquid is contained in the main compartment of the spray can, making it easy and efficient to clean the nozzle, tubes and other interior of the spray can, to minimize the risk of mixing a first and a second concentrate from a first and second capsule inserted in the spray can.
The capsule is leak tight in an inactive state, such as when stored away, and is activated once it is placed in the receptacle of the spray can. The capsule can for example have a silicon gasket, as is commonly known in the art, which prevents the concentrate from leaking from the capsule when not in use.
Water is refilled in the can in ways commonly known in the art, i.e. through a separate opening 6 which can be sealed with a lid or equivalent means. The opening 6 is preferably positioned and adapted to ease refilling from a water tap, and can be refilled without removing the capsule with concentrate.
Figure 2 shows another embodiment of the invention. Some of the features in figure 2 are also shown in figure 3. When a container 15 with concentrate 11 is inserted in a container holder 12, a nozzle or similar means provides access from the container through a restrictor 9 and valves 7b,c or back-flow check valves, and into a mixing chamber 8. The container 15 can also be provided with sealing means 7c such as a one way valve, or a back- flow check valve, depending on the content of the container 15.
The valve 7a in connection with the mixing chamber 8 prevents leakage from the mixing chamber. The valves 7a,b prevents mixing of the content from two different containers. The concentrate in the container is pumped into the mixing chamber when a lever 16 on the spray can is activated or pressed. An activation of the lever 16 provides a vacuum which brings the concentrate 11 from the container 15 into the mixing chamber 8 through among others valves 7b, c, a restrictor 9 and tube 10a. As the lever 16 of the spray can is pressed, water 14 is also pumped from the main compartment through a tube 13 and into the mixing chamber 8 through a one way valve 7a or a back-flow check valve. This ensures that the water in the main compartment is not contaminated with liquid from the mixing chamber. Water 14 and concentrate 11 is mixed in the mixing chamber 8, and a final mix consisting of the correct amount of concentrate 1 and water 14 exits the spray can through a nozzle 17. The nozzle 17 is preferably equipped with different settings for different nozzle spray patterns, as is commonly known in the art, to better adapt to the desired application of the product.
Figure 3 shows a schematic drawing of the principles from figure 2. The mixing chamber 8 is a compartment which works after the principles of a static mixing chamber, also known as a vortex mixing chamber, where two or more fluids are mixed through turbulence in the fluid current. This ensures an efficient mixing of the fluids as they are transported through the mixing chamber 8, without experiencing a significant drop in pressure. The fluids (i.e. the water and the concentrate) leave the mixing chamber as one homogeneous fluid through a tube 18 to the nozzle of the spray can.
