An ink container is used for supplying ink compositions to an apparatus for recording ink jets. It is comprised of an ink chamber that houses the ink and an additional support that connects to the inner wall to help support it. Additionally, there is an ink-pouring port that the ink mixture is to be poured into the chamber.
1. Technical Field
The invention is a pen container that can be attached to an inkjet recording machine. It’s also capable of supplementing the existing composition of ink.
2. Similar Art
In the related art it is known an inkjet recording device that records images or the like on a recording medium with small droplets of ink that discharge from the nozzles on a recording head that records using ink jets. The recording device that uses ink jets has an ink container such as an ink cartridge for giving ink compositions to the recording device.
As such an ink container is known, it has also been identified as an refill (pouring) type of ink container (a known as a continuous supply type ink container) where the continuous supply type of ink container is refilled with an ink mixture instead of replacing theink container. It also has an ink cartridge that is replaceable (a known as an ink cartridge) where the ink container is replaced when an ink composition in the container is greater or less than a specified amount. InJP-A-128511for instance the method of recording ink jets is described that delivers ink via an ink supply tube from a continuous-supply type ink tank to a nozzle. The ink tank comes with an ink refillable design.
In the continuous supply type ink tank described in JP-A-12-2012-148511 is an ink chamber for housing the ink composition is contained therein. In such an ink chamber, a support (such as a rib) is installed to hold the shape of the inkcontainer and to improve its strength or rigidity in some cases.
Continuous supply type ink containers, as described in JP-12-148511 are kind of container that is known as an atmosphere-open. This permits the ink chamber to be opened to the outside air. Inside the ink chamber there exists an interfacial space (gas-liquid interaction) between the air and ink.
When the ink in the ink chamber is consummated, the ink attached to the support gets dried out by getting into contact with the air present in the upper portion of the ink chamber and , consequently, it’s easy to form a thin layer. The resulting thin film can be easily peeled. The peeled film is able to form aggregates within the ink in some cases. The aggregates are then pumped to the head, resulting in the clogging of the head (nozzle).
A filter is also available to take out foreign substances, such as aggregates in the flow path of the ink container. If an ink cartridge type container that can be replaced instead of an ink refill is used even though the aggregates are captured by the filter the ink cartridge is changed before the captured aggregates cause problems for the supply of ink in a lot of cases. This means that the blockage of the filter occurred less frequently. However, the continuous supply type of ink container that is refillable with ink, has a lengthy period of time to use in comparison to the type of ink cartridge ink container, inconveniences such as ink supply failure due to the aggregates that are captured by the filter are easily apparent.
The port for pouring ink on the container for ink can be open to let ink flow into the chamber. But, the port may remain closed and the ink will not be poured in the port. In such instances the air that is present in the upper part of the ink chamber can switch from the air that is saturated state to the outside air. Particularly when the ink inside the chamber is consumed in large quantities and the proportion of air in the upper side of the ink chamber gets greater, a significant amount of the air that is not saturated is introduced into the ink chamber , and thus the ink in the ink chamber becomes rapidly dissolved. In this case the ink that’s attached to the support within the ink is quickly evaporated and thus a huge quantity of aggregates can be created.
Some features of the invention have the benefit of providing an ink container that can be used to reduce the production of aggregates.
The invention may be realized in the following forms or examples of application.
A sample of an application
According to an aspect of the invention, there is provided an ink container that is adapted to supply an ink composition to an ink jet recording device that includes a recording head for discharging the ink composition, the ink container including an ink chamber that houses the ink composition, the ink chamber including a wall defining the ink chamber and a support connected to an inner wall to support the wall and an ink port for pouring through where the ink composition is being poured into the inkchamber in which, in a use state of the container when the ink chamber is filled with the ink to a maximum of 50% of the volume thereof and the area of the support in contact with the ink composition is smaller than that of the support in contact withatmosphere.
In the ink bottle according to Application Example 1, even though the air which is not in the saturated state enters the chamber for ink, the formation of aggregates resulting from the ink bonded to the support contained in the ink is slowed down and an ink jet recording apparatus has excellent stability in discharge of the composition of ink.

What is a patent?
Granted by the government to protect an invention, patents give the inventor exclusive rights to create, use, sell and promote the invention? society gains when a innovative technology is introduced into the marketplace. These benefits may be directly realized as individuals are able to accomplish previously unattainable feats, or indirectly via the opportunities for economic growth which innovation can bring (business expansion, job creation).
Patent protection is demanded out by many universities and pharmaceutical companies to aid in their research and development. Patents can be granted for a product, process, or method of making new materials. In order to be granted protection under a patent an invention has to be innovative, novel and not be obvious to others within the same subject.
Patents recognize and give inventors a reward for commercially successful inventions. They act as a motivator for inventors to invent. Patents allow inventors and small companies to know that there is a good chance they will receive a return for their time, effort and investment in technological development. It means that they can make a living by their work.
Businesses that have the capacity to:
Secure the latest products and services;
Increase the value, appearance, and visibility of your products market
Differentiate yourself and your products from the rest.
Find business and technical information.
Avoid the risk of accidentally using third-party proprietary content or losing important information, creative outputs, or other creative output.
Patents transform the knowledge of inventors into a valuable asset which opens up new opportunities for job creation by licensing joint ventures and joint ventures.
Investors who are involved in the development and commercialization of technology may find small businesses with patent protection to be more attractive.
Patents can lead to new ideas and new inventions. These information may be eligible for protection under patents.
Patents can be used to stop untrustworthy third parties from making money through the work of inventions.
Revenues from patent-protected technology that are commercially successful can be used to finance research and development (R&D), which will improve the chances of developing better technology in the future.
Intellectual property ownership is a way to convince lenders and investors that there are genuine opportunities to market your product. One powerful patent may open the door for numerous financing options. Patents and other IP assets can be utilized as collateral or security to finance debt. You can also show investors your patent assets to boost company valuation. Forbes and others have noted that every patent could add anywhere from $500,000 to million dollars to your company’s valuation.
A well-thought-out business plan is essential for startups. It should be founded on IP and explain the way your product or service is distinctive. Additionally, investors will be impressed when you show that your IP rights are secure or in the process of becoming secure and that they are in line with your business plan.
It is important to keep an invention secret until you submit to protect it with patents. It is important to keep the invention private before filing for patent protection. Public disclosure can often make an invention and render it patent-infringing. Pre-filing disclosures, such as for investors, test-marketing, or any other business partners, must be done only following the signing of a confidentiality agreement.
There are many kinds of patents and knowing the different types is crucial to protect your invention. Utility patents cover inventions and processes that are new. Design patents cover ornamental designs. Utility patents are the best because they shield the owner from copycats and other competitors. Patents for utility are usually granted to enhance or modify existing inventions. Utility patents can also be used to cover improvements and changes to existing inventions. A process patent could cover the acts or methods of performing a specific act. But, a chemical composition will include the combination of components.
How long will a patent last? Although utility patents are valid for 20 years from the date of their earliest filing, they are able to be extended through delay at the Patent Office.

After the patent office approves your application, you will be able to do an examination of the patent number to locate the patent issued. The product you are selling will now become patented. You can also utilize the USPTO search engine. Check out the following article for more information. A patent lawyer or patent attorney can advise you on the procedure. In the US patents are issued by the US patent and trademark office as well as the United States patent and trademark office, which also reviews trademark applications.
Are you interested in finding similar patents? These are the steps:
1. Think of terms to describe your invention based on the purpose, composition and application.
Start by writing down a brief and precise description of your idea. Avoid using generic terms like “device,” “process,” and “system.” Instead, think about synonyms for the terms you initially chose. Then, note important technical terms as well as keywords.
Use the following questions to help you identify the keywords or concepts.
- What is the objective of this invention? Is it a utilitarian device or an ornamental design?
- Is inventing a method to create something or perform an action? Or is it a product or procedure?
- What is the nature and purpose of the invention? What is the physical makeup of the invention?
- What is the purpose of the invention?
- What are the terms and phrases in the field of technology used to describe an invention’s nature? A technical dictionary can help you identify the correct phrases.
2. Utilize these terms to find pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. If you are unable to locate the appropriate classification to describe your invention, look through the classification’s Schemas of classes (class schedules). You may want to consider substituting the terms you use to describe your invention if you don’t find any results in your Classification Text Search with synonyms similar to the words you used in the first step.
3. Go through 3. Go over the CPC Classification Definition to confirm the validity of the CPC classification that you have located. If the selected classification title has a blue box with the letter “D” at its left, clicking on the hyperlink will take you to the CPC classification’s description. CPC classification definitions can help determine the scope of the classification which is why you can be sure to select the most appropriate. The definitions could also contain some search tips or other recommendations which could prove useful in further research.
4. The Patents Full-Text Database and the Image Database allow you to retrieve patent documents that include the CPC classification. You can review and find the relevant patent publications by looking first at abstract and representative drawings.
5. This selection of patent publications is the best to check for connections to your idea. Be sure to read the claims and specifications. There are many patents available through contacting the patent examiner and applicant.
6. Retrieve published patent applications with the CPC classification you chose in Step 3 in the Applications Full-Text and Image Database. It is also possible to use the same strategy of searching you utilized in step 4 to limit down your results to the most relevant patent applications by looking over the abstracts and representative drawings on every page. Then, you must carefully review the patent applications that have been published with particular attention paid to the claims and the additional drawings.
7. Locate additional US patents by keywords in the PatFT or AppFT databases, searching for classification of non-U.S. patents as described below, and searching for non-patent literature disclosures of inventions using internet search engines. For example:
- Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
- Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
- European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents.
- Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
- World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
- Korean Intellectual Property Rights Information Service (KIPRIS)
- State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
- Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
- Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.
To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
