Description

Valved dosing packing with dosing chamber and refilling storage chamber

Field of the invention

The present invention relates to a valved packaging meant to store and distribute liquids in predetermined amounts (doses) and make the dilution of small amounts of the product possible for use in the packing itself.

Background of the invention

In the BR PI9203929 document, issued on 08/10/1992, the construction of the packing flask style is taught, it is designed to distribute a determined dose of its content, meant mainly for laundry softener, starch, disinfectant, sterilizer, shampoos and medicines. The device that makes the doses is formed by the element that closes the flask. It is closed in its superior part by an articulated lid, when the lid is opened and the flask is pressed the liquid content is expelled into the conformed cavity in the closing element as to fill the mentioned cavity, whose volume corresponds to the wanted dose of liquid.

With the ceasing of the pressure caused by the expelling of the liquid, the air penetrates into the flask by the discharge opening reestablishing the original format of the flask.

This construction presents some limitations in its application in reference to the measurement of different amounts of the content, restricting it to the amount determined by the small volume of the closing device. Besides such construction does not predict, nor allow the configuration of a storage space for the dose and/or the dilution of the portion of the product

The technique herein is already known by the patent application BR PI0002444 issued on 01/08/2002 to the same titleholder of this patent, a container for the transport and storage of a liquid substance to be divided into portions and diluted in a chamber of the same recipient. The packaging construction presented by the above mentioned document aims at the manipulation of products in large amounts as in the case of cleaning products for hospitals, schools and similar facilities. The use of the packing is neither economically viable nor adequate for dermatological, hygiene or personal care products. The present technique does not forecast a domestic usage for the packaging that allows product savings through the dilution of the product in the same packaging. Such dilution results in product saving that is many times advised by the manufacturer in view of the product concentration rate unnecessary for the end use which is the case of shampoos, detergents, liquid soap and laundry softeners.

The stowage of substances for personal and domestic usage for later dilution in packaging designed according to the already known concepts would represent a packaging price increase. The simple adjustment of a chamber for dilution of the content would result in a too large and expensive package that after the last dose would be discarded.

Therefore the mere transposition of the known techniques would not result in an economically viable product. Object of the invention

The present patent aims at overcoming the previously mentioned technical limitations and the attainment of a container with a new concept and technical effects. It is related to the construction of a packaging for the transportation and commercialization of products of personal and domestic use. It is forecasted for divisions into portions and dilution or even for mixing with some other product that allows the dosage and dilution of the product within a measuring and blending chamber apart from the recipient of the concentrated product.

The objective of the present invention is a packaging for the transportation and commercialization of products of personal and domestic use with a device that incorporates system of valves for the release of the product and control of air input for the balance of the internal pressure of the packaging that makes the maintenance of a chamber with a diluted dose ready for usage possible independent from the recipient with the rest of the concentrated product. The present invention also intends to create a packaging for the transportation and commercialization of products of personal and domestic use presenting an innovative and simple construction that is achieved at a reduced and reasonable cost. The present invention also intends to create a packaging for the transportation and commercialization of products of personal and domestic use presenting the possibility of prolonged use and reutilization of the package after the product is used up. Therefore, it is designed to be recharged with the concentrated product. Disclosure of the invention To reach the mentioned objectives the present invention presents a packaging that is configured as a flask for the distribution of predetermined doses of the products for personal or domestic usage. It presents a packaging construction with a valve system in the central region of the packaging that makes the formation of a dosage and mixing chamber in the superior part of the recipient.

This chamber is placed above the discharge valve avoiding that the content of the mixing chamber interferes with the concentrated product that is stored in a recipient that constitutes the inferior part of the packaging that is attached to, but that can be released from the packaging below the valved system.

According to the present invention the recipient in the part below is rechargeable or replaced by a new one when its content is over. Still in accordance with the present invention the product recharge in the recipient below the packaging is also designed to be made by the replacement of the sachet that is placed inside the bottom recipient.

In the present construction the concentrated product is commercialized at a low cost in the form of sachet or cushion. This eliminates the need for a final packaging more elaborate and expensive consequently making the transportation, storage and distribution of the product easier and more cost effective.

Brief description of the drawing In order to allow the total understanding of the object of the present patent, the invention is described in full detail and displaying the drawings in which: FIG. 1 - Sectional view of the packaging according to the present invention in exploded condition. FIG. 2 - Sectional view with the lower recipient distinguished from the packaging built according to the present invention. FIG. 3 - Sectional view of the packaging built according to the present invention. FIG. 4 - Sectional view of the packaging built according to the present invention in exploded condition with recharge refill. FIG. 5 - Sectional view with the lower recipient distinguished from the packaging built according to the present invention with recharge refill. FIG. 6 - Sectional view of the packaging built according to the present invention with recharging refill, As we conclude from the drawings of the packaging (1) it is built in three independent sectors. A lower recipient (2) a ring shaped central valved segment (3) and a superior mixing and dosage chamber (4).

The three parts (2) (3) (4) when joined together form a flask (1) of proper dimensions for domestic handling of products such as shampoos, liquid soap, laundry softener. The variation of the final form and volume of the packaging are included in the scope of the present patent.

The ring shaped segment of the packaging (3) presents a central cylinder opening (5) of ejection where there is a one-way valve (6) placed in upward direction, for use with liquids and semi liquids, that contains in its inferior part a flexible collecting tube (7) that has to be long enough to reach the bottom of the inferior recipient (2).

The ring shaped segment (3) is screwed in its external upper extremity (27) and a closing surface (8) with a central round opening (5) that limits an internal cylindrical region (9) that must be big enough to hold a valve (6). Below the cylindrical part (9) where the valve is placed (6) the ring shaped segment presents a wider cylindrical extension (10) from which an inferior closing surface extends (11).

This wider cylindrical extension has a lateral orifice for air input (12). This air comes from a duct placed horizontally inside the ring shaped segment (3) where there is an one-way air valve (13) that interacts with the exterior environment.

This cylindrical extension (10) is screwed and receives the bottleneck (21) of the bottom recipient (2) externally screwed linking the valved ring shaped segment to the bottom recipient (2). The bottleneck (21) of the bottom recipient (2) has a small lateral opening (14) that when linked to the bottom recipient (2) with the ring shaped segment (3) must be disposed in the direction of the air opening (12) to allow the input of air into the bottom recipient to provide the internal pressure balance and the return to its original form after the expelling of the dose of the product by means of pressing and the deformation of the walls of the recipient that are built in a flexible or semi flexible material.

The small lateral opening or orifice (14) of the bottleneck (21) of the bottom recipient (2) may have the configuration of a small horizontal slot to facilitate the relative positioning of the bottom recipient (2) with the ring shaped (3) segment. The position of the small lateral opening (14) is indicated through a mark in the body of the recipient below the connection making the alignment with the orifice of the cylindrical region (10) with the lateral opening of the bottleneck easier (21).

The upper dosage and mixture chamber (4) is built by a tubular body (15) with a lower closing wall (25) dislocated from the lower extreme of the wall of the tubular body (15) presenting a central circular opening (26) for the passage of the liquid valve (6). The lower extreme of the tubular body wall has an internal screw (16) to link to the ring shaped segment (3).

The upper dosage and mixture chamber (4) presents in its upper extremity a closing wall (17) with a discharge opening (18) that has a closing lid (not shown in the figure).

The discharge opening (18) illustrated in an overview as a bottleneck may take any other form suitable for the end use it is destined as for example dosage pump for liquid soap, articulated nozzle for shampoos, screwed lid for laundry softener etc

The chamber (4) shows a certain transparence and one or more external marks of amount of concentrated product volume (22)

(doses).

In the construction shown in figures 1 , 2 and 3 the concentrated content is commercialized in the complete packaging (1) or in a recipient that corresponds to the bottom recipient (2) which will also be a refill.

In the figures 4, 5, and 6, the construction shows that the concentrated product is in a sachet (19) or cushion, which is replaceable when the product is over. In this case it is forecasted that in the place of the flexible collecting tube (7) a rigid one (20) is adopted. When the ring shaped segment (3) is joined to the bottom recipient it perforates the sachet and when the bottom recipient is pressed the concentrated product is impelled through the rigid collecting tube (20) through the one-way valve (6) into the dosage and mixing chamber.

In this conception, the bottom recipient (2) is shown in the form of a cup to hold the sachet (19) with an extension of the external surface (23) screwed in its upper extremity to be screwed in the valved ring shaped segment (3) that presents in its bottom extremity an extension in the internal surface (24) screwed. After placing or replacing the sachet (19) inside the bottom recipient in the form of cup (2), the rigid collecting tube (20) is placed at the center of the sachet (19) perforating it and then the bottom recipient (2) is screwed to the ring shaped segment (3).

The internal pressure is balanced by the air admitted by the air valve (13) that connects the bottom recipient defined internal space with the environment.

The pressure on the walls of the bottom recipient (2) closes the air valve (13) and the pressure is transferred to the liquid that is then admitted to the collecting tube (7) (20) that through the one-way liquid valve (6) moves into the dosage and mixture (4) or dilution chamber.

When the amount of concentrated product fills up the chamber (4) the pressure on the walls is released and the one-way air valve allows the air into the bottom recipient (2). The dose of the concentrated product that is in the upper chamber (4) is diluted there and used until it is over when a new process of dosage and dilution is performed.
