Synthetic resin containers (e.g. PET bottles) with a bottle-like shape with a tube-shaped mouth the tube-shaped trunk that has one end that is closed with the bottom, and another shoulder through which the other part of the trunk connects to the mouth. They have been widely employed as containers that hold a variety of liquids, like a seasoning including soy sauce, beverage and cosmetics product shampoo, as well as a liquid detergent.
The container of this synthetic resin can be made by blow molding a preform using pressurized water. The preform has been formed by thermoplastic resin in a bottomed tubular shape. Patent Literature 1 describes, for instance, a resin container made by using a bottomed tubular preform to biaxial stretch molding by using pressurized oxygen to stretch portions that are corresponding to the shoulder, trunk, and bottom in the axial or circular directions, and then forming a bottle form.
The shoulder of the container made of synthetic resin with the bottle shape is often a substantially conical shape that is inclined with respect to the axis of the mouth.
The biaxially stretch-blow molded resin container is characterized by an increased angle of inclination for the shoulder in relation to the axis. This means that there is an increase of draw ratio in the direction of machine of a part of the preform that corresponds with the shoulder during blow molding. Therefore, if the vessel has a shape in which the shoulder is inclined towards the axis direction of themouth, the shoulder, even having the same crystallinity is more likely to contract after molding. Especially when the container has an outline in which the shoulder is tilted at an angle higher than 120.degree. The rate of shoulder contraction after molding is greater than the axis that runs through the mouth. This may result in a decrease in the container’s size and the deformation.
To address this issue, the present disclosure was created. The present disclosure provides a synthetic resin container and an approach to making it. This prevents the decrease in size and deformation. It also allows the shoulder to be angled to an angle greater than 120.degree. relative to the jaw’s axis.
One aspect of the disclosed invention resides in a container made of synthetic resin with a bottle-shaped shape, comprising a tube-shaped mouth, a tube-shaped trunk having one end sealed by an upper and a shoulder through which a different end of the trunk isconnected to the mouth, and the shoulder is bent at an angle higher than 120.degree. relative to the axis of the mouth and the shoulder is positioned with an orientation of the crystals in a direction that is less than 1.
In the currently disclosed synthetic resin container with the above design, the mouth could be formed in a substantially cylindrical shape, the trunk could be constructed in a substantially cylindrical shape with a diameter larger than adiameter of the mouth, and the shoulder can be formed in a substantially frustoconical shape.
Polyethylene Terephthalate can be used to make the synthetic resin container described in the above-described arrangement.
Another aspect of the disclosure is the production method for the container made of synthetic resin described above. This involves supplying the preform that is formed by thermoplastic resin in a bottomed tubular shape, a liquid heated at a predetermined temperature and pressure to liquid blow mold it.
The present invention provides an artificial resin container as well as the method for making the container made of synthetic resin and both of them prevent diminution in volume and deformation by limiting the degree of shoulder contraction while still allowing the shape of the shoulder to be inclined at an angle greater than 120.degree. With respect to the axisof the mouth.Click here to view the patent on USPTO website.

What is a patent?
Patents are granted by the government to safeguard the invention. It gives the inventor the right to create, use and sell the invention. Society gains when new technology is introduced to the market. Benefits can be realized in directly, in that it allows people to accomplish previously unattainable things. Or indirectly, through the economic opportunities (business expansion and job creation) that innovation provides.
Patent protection is demanded by many pharmaceutical companies and university researchers for their research and development. Patents may cover a physical or abstract product or process , or an approach or composition of materials that are new to the area. In order to be granted protection under a patent, an invention must be useful, new, and not obvious to anyone else in the same field.
Patents are a way to honor inventors who have commercially successful inventions. They are an incentive to inventors to create. Small companies and inventors can be sure that they will earn a return on their investment in technology development via patents. They could earn a decent income from their work.
Patents are essential to companies, and they can:
Secure the latest products and services;
Improve the value, the appearance, and visibility of your products on the market;
Differentiate your business and products from the rest;
Get business and technical details.
Avoid the danger of accidentally using third-party proprietary content, or losing valuable data, original outputs, or other creative output.
Patents transform inventors’ information into a tradeable asset that opens up new possibilities for job creation and business expansion by licensing or joint ventures.
Investors who are involved in the development and commercialization of technology may find small companies with patent protection to be more attractive.
Patenting can lead to new ideas and inventions. This information could be protected by patents.
Patents can be used to prevent untrustworthy third-party companies from earning through the work of inventions.
Patent-protected technology revenues that are commercially profitable could be used to fund research and development (R&D) that will improve the chances of better technology in future.
Intellectual property ownership is a way to convince lenders and investors that there are real opportunities to market your product. Sometimes, one powerful patent could open the door to multiple financing opportunities. Patents as well as other IP assets can be utilized as collateral or security for financing debt. You may also present investors with the patents you own to increase company valuation. Forbes and others have stated that each patent could increase the value of your company by as much as $500,000 to $1 million.
A solid business plan is vital for new businesses. It must be founded on IP and demonstrate what your service or product stands out. Investors will be impressed if you have IP rights are secured or are on the verge of being secured, and they agree with your business strategy.
It is essential to protect an invention before submitting a patent application. Making an invention public before it is filed is often detrimental to its novelty and render it unpatentable. The filing of disclosures prior to filing, for example, for investors, test-marketing or other business partners, is best done after signing a confidentiality agreement.
There are a variety of patents, and understanding these is vital to safeguard your invention. Utility patents cover new techniques and machines. Design patents cover ornamental designs. Patents for utility are the most effective as they protect the owner from copycats and competition. Most often they are granted to improve or modify existing inventions. Utility patents also cover enhancements and modifications to existing inventions. A process patent will be a way to describe the actions or methods to perform a particular action. But, a chemical composition will include an amalgamation of ingredients.
What is the average length of a patent? Patents for utility last for 20 years after the earliest filing dates, but their expirations may be extended due to delays at the patent office for instance.

You’ll be able to get a better idea of what your invention should be and be better prepared to write the patent application.
How to Search for Patents
The first step in obtaining your patent is to perform the patent search. You can do a google patent search or do a USPTO search. Once the patent application is submitted, the product that is covered by the application can be called patent-pending, and you will be able to locate the patent application online on the public pair. After the patent office approves your application, you will be able do an online search for a patent number and locate the patent issued. Your product is now patentable. Alongside the USPTO search engine, you can use other search engines, such as espacenet, as detailed below. A patent lawyer or patent attorney can assist you with the procedure. In the US, patents are granted by the US patent and trademark office or the United States patent and trademark office, which also examines trademark applications.
Are you looking for similar patents? These are the steps:
1. Create a list of terms for your invention according to its function and composition or usage.
Write down a brief and precise explanation of your invention. Be sure to avoid using terms that are generic such as “device,” “process,” and “system.” Look for synonyms to the terms you initially chose. Also, keep track of crucial technical terms, as well as keywords.
To help you recognize the key words and concepts, try the questions below.
- What is the objective of the invention? Is it a utilitarian device or an ornamental design?
- Invention is a method to make something or carry out some function? Are you referring to an item?
- What is the composition of the invention? What is the physical composition of the invention?
- What is the goal of the invention
- What are the terms in the technical field and the keywords that define the nature of an invention? To assist you in finding the appropriate terms, use a technical dictionary.
2. Use these terms to search for relevant Cooperative Patent Classifications at the Classification Text Search Tool. To determine the best classification for your invention, go through the resulting classification’s class Schemes (class schedules). Think about substituting the words that you’ve used to describe your invention if you do not find any results in your Classification Text Search with synonyms such as the terms you used in Step 1.
3. Go through the CPC Classification Definition to verify the relevancy of the CPC classification that you have located. If the classification you have selected includes a blue square with the letter “D” at its left, the hyperlink will take you to the CPC description of the classification. CPC classification definitions will assist you in determining the classification’s scope so that you can choose the most appropriate. Additionally, these definitions can include research tips and other suggestions that could be helpful in further research.
4. Get patent documents using the CPC classification from the Patents Full-Text and Image Database. By focusing on abstracts and drawings that are representative, you can narrow down your search to find the relevant patent documents.
5. Use this selection of the most pertinent patent documents to examine each one in depth for any similarity to your idea. Be sure to read the claims and specifications. You may find additional patents by referring to the patent examiner and the applicant.
6. It is possible to find patent applications published in the past that fit the CPC classification you selected in Step 3. You may also employ the same method of search that you employed in step 4 to limit down your search results down to just the most relevant patents by reading the abstracts as well as the drawings for each page. Then, you must carefully review the patent applications published, paying particular attention to the claims as well as additional drawings.
7. Find other US patents by keyword searching in PatFT or AppFT databases, classification searching of non-U.S. patents as per below, and searching non-patent patent disclosures in the literature of inventions using internet search engines. Here are some examples:
- 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.
