Definitions

  • the present invention generally relates to a dispensing closure and more particularly to a dispensing closure for a container, enabling at least one substance to be dispensed and mixed with other substance within the container.
  • a container closure which includes a capsule for storing material separate from the container for the purpose of selectively mixing the material with the contents of the container.
  • Protein powders, energy mixes, supplements or other nutritional products are examples of materials frequently used in conjunction with common food articles to promote a healthy lifestyle.
  • foods, beverage, nutritional supplements, nutraceuticals, drugs, cosmetics, and chemicals which are frequently supplied in liquid, powder, paste or other forms do not retain their stability, strength and effectiveness for long after they have been mixed, either in solution or suspension.
  • This incompatibility after mixing therefore mandates that the product be utilized relatively soon after mixture to prevent deterioration, discoloration, interactions and the like.
  • admixtures of various ingredients be done under conditions wherein it can be assured that a measured amount of one ingredient is added to a measured amount of one or more ingredients, to ensure that the desired results are obtained.
  • non-active and active substances such as activated oxygen, vitamins, minerals, herbs, nutrients or flavouring that would be desirable to be added to these desirable liquids such as water, juices or other beverages to give the consumer added benefits, particularly those useful for the health of the consumer.
  • these desirable liquids such as water, juices or other beverages to give the consumer added benefits, particularly those useful for the health of the consumer.
  • Many of the substances, however, that provide additional benefits when mixed into another liquid have short shelf lives and are likely to discolour, interact or degrade quickly when combined with liquids or other substances. Therefore, many desirable liquids are currently sold without the added beneficial ingredient.
  • One method employed to provide such results is utilizing a container having two capsules in which two ingredients may be stored separately until it is desired to mix them, at which time it is possible to establish communication between the capsules so that the separated ingredients may move from one capsules to the other.
  • dispensers containing a concentrate of soluble materials to a fixed quantity of solute, usually water, for dispensing are known in the art to provide dispensers containing a concentrate of soluble materials to a fixed quantity of solute, usually water, for dispensing.
  • the prior art teaches containers for beverages wherein the interior of the container is divided into a capsule having a basic ingredient and a capsule which can be ruptured so as to mix within the container the basic ingredient and some form of modifier, diluent or flavoring.
  • the reason for this prior art container is to provide the mixing action at the time of consumption since prior mixing would have adverse effects.
  • the basic ingredient is often not suitable for consumption by itself and requires mixing with a diluent / modifier prior to consumption.
  • U.S. Pat. No. 7, 017, 735 B2 discloses a cap for use with a container which includes a ring member.
  • a capsule extends through an opening that is substantially centered on the recess portion of a closure ring of the container.
  • a plunger is provided on an interior wall of the capsule.
  • the capsule contains a substance, such as water-dispersible liquid.
  • the container having a main chamber and a mouth stores and serves a beverage.
  • the main chamber is filled with a single strength beverage and the capsule is filled with water dispersible liquid.
  • the capsule is placed in the mouth of the container contiguous to the main chamber, with the capsule being openable to inject the water-dispersible liquid in the single strength beverage in the main chamber in response to manual manipulation of the capsule.
  • WO/2005/081732 discloses an instant drink bottle which includes a body closed by cap, with liquid and a capsule with an ingredient such as flavouring agent, a colour, a preservative, vitamin or drug.
  • the cap and capsule co-operate so that when the cap is manipulated by the user, an opening is formed in the capsule thereby releasing the ingredient into the liquid.
  • WO/2006/115506 discloses a mixing cap and method for use thereof, wherein the mixing cap is preferably pre-loaded during manufacture with a selected dry or liquid ingredient to facilitate consumer use.
  • the mixing cap has an apertured inner tube to the mouth of a bottle and an outer housing co-operatively engaged to the inner tube and slidably restricted thereover via a flange arrangement.
  • Preloaded ingredients contained within the outer housing may be introduced or discharged into the bottle by simply depressing the outer housing over the inner tube, permitting the ingredients to flow through the apertures of the inner tube and into the liquid contents of the bottle.
  • the combined ingredients and liquid within the bottle may subsequently be shaken without fear or risk of leakage or spillage.
  • WO/2006/052827 discloses a dispenser comprising a housing that has a removable tamper-proof protective cap and tamper-proof ring and is threaded to a container.
  • the container which is the main package, holds a supplemental component.
  • the housing holds the first component into a plunger-type chamber in a fully retracted position and is sealed from the supplemental component.
  • the chamber has a delivery end that is closed before use. When pushed all the way in, the chamber's delivery end becomes open and delivers the first compartment into the main package.

Description

DISPENSING CLOSURE FOR CONTAINER
FIELD OF INVENTION
The present invention generally relates to a dispensing closure and more particularly to a dispensing closure for a container, enabling at least one substance to be dispensed and mixed with other substance within the container.
BACKGROUND OF INVENTION
The concept of a container closure which includes a capsule for storing material separate from the container for the purpose of selectively mixing the material with the contents of the container is known in the art. Protein powders, energy mixes, supplements or other nutritional products are examples of materials frequently used in conjunction with common food articles to promote a healthy lifestyle. However, foods, beverage, nutritional supplements, nutraceuticals, drugs, cosmetics, and chemicals which are frequently supplied in liquid, powder, paste or other forms do not retain their stability, strength and effectiveness for long after they have been mixed, either in solution or suspension. This incompatibility after mixing therefore mandates that the product be utilized relatively soon after mixture to prevent deterioration, discoloration, interactions and the like. It is also important that admixtures of various ingredients be done under conditions wherein it can be assured that a measured amount of one ingredient is added to a measured amount of one or more ingredients, to ensure that the desired results are obtained.
Another concern involves the merchandising of certain products. Some products are, by their nature, required to be used by the consumer shortly after their manufacture and mixture as they lose certain desirable characteristics within a short period of time. Yet the product can be stored for extended periods of time if one ingredient is maintained separate from the other, and the two ingredients only mixed together to form the desired product shortly before use. In marketing such goods, it obviously is desirable that both ingredients be sold as part of the same container rather than two or more companion ingredients in separate containers be supplied to the consumer. Thus from an aesthetic as well as handling standpoint, it is desirable that just a single container be utilized for maintaining the separation of such ingredients. The use of conventional liquid containers such as plastic bottles for carrying water, juices, power drinks or other desirable liquids for human consumption is known. There are, however, several non-active and active substances such as activated oxygen, vitamins, minerals, herbs, nutrients or flavouring that would be desirable to be added to these desirable liquids such as water, juices or other beverages to give the consumer added benefits, particularly those useful for the health of the consumer. Many of the substances, however, that provide additional benefits when mixed into another liquid have short shelf lives and are likely to discolour, interact or degrade quickly when combined with liquids or other substances. Therefore, many desirable liquids are currently sold without the added beneficial ingredient.
One method employed to provide such results is utilizing a container having two capsules in which two ingredients may be stored separately until it is desired to mix them, at which time it is possible to establish communication between the capsules so that the separated ingredients may move from one capsules to the other. It is known in the art to provide dispensers containing a concentrate of soluble materials to a fixed quantity of solute, usually water, for dispensing. Thus, the prior art teaches containers for beverages wherein the interior of the container is divided into a capsule having a basic ingredient and a capsule which can be ruptured so as to mix within the container the basic ingredient and some form of modifier, diluent or flavoring. The reason for this prior art container is to provide the mixing action at the time of consumption since prior mixing would have adverse effects. The basic ingredient is often not suitable for consumption by itself and requires mixing with a diluent / modifier prior to consumption.
U.S. Pat. No. 7, 017, 735 B2 discloses a cap for use with a container which includes a ring member. A capsule extends through an opening that is substantially centered on the recess portion of a closure ring of the container. A plunger is provided on an interior wall of the capsule. The capsule contains a substance, such as water-dispersible liquid. The container having a main chamber and a mouth stores and serves a beverage. The main chamber is filled with a single strength beverage and the capsule is filled with water dispersible liquid. The capsule is placed in the mouth of the container contiguous to the main chamber, with the capsule being openable to inject the water-dispersible liquid in the single strength beverage in the main chamber in response to manual manipulation of the capsule.
WO/2005/081732 discloses an instant drink bottle which includes a body closed by cap, with liquid and a capsule with an ingredient such as flavouring agent, a colour, a preservative, vitamin or drug. The cap and capsule co-operate so that when the cap is manipulated by the user, an opening is formed in the capsule thereby releasing the ingredient into the liquid.
WO/2006/115506 discloses a mixing cap and method for use thereof, wherein the mixing cap is preferably pre-loaded during manufacture with a selected dry or liquid ingredient to facilitate consumer use. The mixing cap has an apertured inner tube to the mouth of a bottle and an outer housing co-operatively engaged to the inner tube and slidably restricted thereover via a flange arrangement. Preloaded ingredients contained within the outer housing may be introduced or discharged into the bottle by simply depressing the outer housing over the inner tube, permitting the ingredients to flow through the apertures of the inner tube and into the liquid contents of the bottle. The combined ingredients and liquid within the bottle may subsequently be shaken without fear or risk of leakage or spillage.
WO/2006/052827 discloses a dispenser comprising a housing that has a removable tamper-proof protective cap and tamper-proof ring and is threaded to a container. The container, which is the main package, holds a supplemental component. The housing holds the first component into a plunger-type chamber in a fully retracted position and is sealed from the supplemental component. The chamber has a delivery end that is closed before use. When pushed all the way in, the chamber's delivery end becomes open and delivers the first compartment into the main package.
It is known that bottled drinks with bioactive extracts are usually added with preservative to avoid microbial growth. However, adding preservative will give an unhealthy perspective. Hence, the usage of preservative can be avoided by the use of the dispensing closure of the present invention. It is also known that bioactive extracts are easily degraded in water or liquid. By using a novel dispensing closure of the present invention, the shelf live for the products will be extended.
The present invention provides a novel dispensing closure that can be conveniently used . whereby premix can be made easily prior to consumption. Accordingly, different ingredient can be kept in different storage members or vials before mixing into a drink. This will also allow on-the-spot premix, which will maintain the freshness of the beverage.
Moreover, the use of the novel dispensing closure enhances the logistics of the beverage where transportation of water can be avoided. Accordingly, the ingredients can be kept in the dispensing closure for transportation, whereas water or liquid can be sourced locally.
Furthermore, the present invention provide a novel dispensing closure that is easy to use and can be conveniently activated, in a highly sanitary manner, upon manual manipulation by consumer. The present invention uses a minimum number of parts, which renders it simple to manufacture and assemble.
