What is a Patent for Container made of synthetic resin and the manufacturing process for it.
Search Patent for Container made of synthetic resin and the manufacturing process for it.
Containers made of plastic (e.g. PET bottles) with an elongated mouth that is shaped like a bottle and a trunk that has one end joined by an arm and the other end joined by a shoulder. They have been widely used for containers to store a variety of liquids, including cosmetic products, shampoo, beverages, shampoo and detergent.
The container of this synthetic resin can be created by blow molding a preform with pressurized water. The preform was made by thermoplastic resin and is a bottomed tubular shape. Patent Literature 1, for example, describes a syntheticresin container made by exposing a bottomed tubular preform to biaxial stretch blow molding using pressurized air to stretch the portions of the preform which correspond to the trunk, the shoulder and the bottom in the radial and axial directions into a predetermined bottle shape.
Patent Literature
Technical Issue
The shoulder of the synthetic resin container with the bottle shape is typically frustoconical, and inclined toward the mouth.
The biaxially stretch-blow molded resin container has a higher angle of inclination for the shoulder relative to axis. This implies that there’s an increase in draw ratios in the machine direction for the portion of preform that corresponds with the shoulder in blow molding. The shoulder tends to expand after molding if container’s design is too incline in relation to the direction of themouth. Particularly, when the shape of the container is an elongated shape where the shoulder is tilted at an angle higher than 120.degree. The rate of shoulder contraction after molding is higher than the axis of the mouth. This can lead to an increase in the container’s volume as well as deformation.
To address the above issue, the present disclosure was created. The present disclosure is a synthetic resin container and also the method of making it. This prevents the decrease in volume and the deformation. It also allows the shoulder to be angled to an angle greater than 120.degree. In relation to the axis of the mouth.
Solution to Problem
One aspect of the disclosed invention is a synthetic resin container that has a tube-shaped mouth as well as an elongated tubular trunk. The trunk’s opposite end is connected to the mouth via a shoulder. with respect to an orifice of the mouth and the shoulder has a crystal orientation to a machine direction of less than.
The synthetic resin container may include a mouth that is significantly cylindrical, a trunk that has a diameter greater then the mouth and a shoulder that is frustoconical.
The synthetic resin container with the above configuration may be made of polyethylene terephthalate.
Another aspect of the disclosure resides in a method for making the currently described synthetic resin container as previously described, the process includes supplying to a preform which has been made by thermoplastic resin into abottomed tubular shape, a liquid that is heated to a predetermined temperature at a predetermined pressure to create a liquid blow mold the preform.
Advantageous Effect
The present disclosure discloses a resin-based synthetic container and a method for making it. This stops the deformation and shrinkage of the shoulder and permits the shoulder to be bent to an angle higher than 120.degree. relative to the jaw’s axis.

What is a patent?
Patents are issued by the government to protect the idea. It gives the inventor the sole rights to create, use and market the idea. Society is benefited when new technologies are brought for sale. The benefits can be in directly, in that it can allow people to accomplish previously unattainable things, or indirectly by the economic benefits (business expansion and job creation) that innovation provides.
A lot of pharmaceutical companies and researchers at universities seek patent protection for their work and research. Patents are granted for the creation of a product, process or method of creating new materials. In order to be granted protection under a patent, an invention must be innovative, novel and not be obvious to other people in the same subject.
Patents give inventors a chance to be recognized for commercially successful inventions. They serve as a motivator for inventors to come up with new ideas. Patents permit inventors and small companies to know that there is a good chance they will be paid back on their time, effort and money spent on the development of technology. This means they will be able to earn a living from their work.
Businesses that have the capacity to:
Protect innovative products and services;
Increase the visibility and value of your product’s presence on the market
Your business and your products should be distinguished from the competition;
Find out about 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 effectively transform the inventor’s knowledge into a commercially tradeable asset that opens up new possibilities for job creation and business expansion through joint ventures or licensing.
Investors in the development and commercialization of technology may find small companies with patent protection to be more attractive.
Patents can spark new ideas and new inventions. The information you create may be eligible for protection under patents.
Patents are a way to stop untrustworthy third parties from making money from the invention’s efforts.
Revenues from patent-protected technology that are commercially successful can be used to fund the development of technology through research and development (R&D), which will improve the chances of developing better technology in the coming years.
Intellectual property ownership can be used to convince investors and lenders that there are genuine chances to commercialize your product. One powerful patent may lead to multiple financing opportunities. You can use patents and other IP assets as collateral or security financing. Investors may also look at your patent assets to boost the value of their company. Forbes and other publications have stated that each patent could increase the value of your company by as much as $500,000 to $1 million.
A properly-written business plan is essential for startups. It should be built on IP and demonstrate the way your product or service stands out. Investors will be also amazed if you have IP rights are secure or are in the process of becoming secure, and if they are in line with your business strategy.
It is vital to protect an invention prior to filing for patent protection. The public divulging of an invention prior to filing is often detrimental to the novelty of the invention and make it invalid. Thus, disclosures that are filed prior to filing (e.g., for test-marketing investors, test-marketing, or any other business partners) should only be filed after signing a confidentiality agreement.
There are numerous types of patents. Understanding them is crucial for protecting your invention. Utility patents protect new processes and machine creations. Design patents cover ornamental designs. Utility patents are the most beneficial because they shield the owner from copycats and competition. Frequently they are granted for alterations or improvements to existing inventions. They can also be used to enhance or modify existing inventions. A process patent will describe the methods or actions to perform a particular action. But, a chemical composition will include an amalgamation of ingredients.
What is the average length of patents? While utility patents are valid for 20 years from the date of the initial filing, they can be extended through delay in the patent office.

Are you looking for similar patents? Here are the steps:
1. Brainstorm terms that describe your invention based on the purpose, composition and use.
Write down a concise and precise description of the invention. Do not use generic terms such as “device,” “process,” and “system.” Instead, consider synonyms to the terms you chose initially. Next, note important technical terms as well as keywords.
Use the questions below to help you determine the keywords or concepts.
- What is the objective of the invention Is it a utilitarian device or an ornamental design?
- Does the invention consist of a method of creating something or performing a function? Is it an object?
- What is the purpose and composition of the invention? What is the physical constitution?
- What is the purpose of the invention?
- What are technical terms and phrases that define the characteristics of an invention? To assist you in finding the right terms, refer to a technical dictionary.
2. Utilize these terms to locate pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. If you’re not able to determine the correct classification for your invention, look through the Schemas of classes (class schedules). If you don’t get any results using the Classification Text Search, you may want to consider replacing the words that describe your invention with synonyms.
3. Go through the CPC Classification Definition for confirmation of the CPC classification you have found. If the selected classification title has a blue box with an “D” to its left, the link will lead you to a CPC classification’s description. CPC classification definitions can be used to identify the specific classification’s scope, so you are sure to select the most pertinent. These definitions may also include search tips or other suggestions that can be useful for further investigation.
4. The Patents Full-Text Database and the Image Database allow you to find patent documents that are accompanied by the CPC classification. By focusing on abstracts and illustrations, you can narrow down your search for the relevant patent documents.
5. This collection of patent publications is the best to check for similarities to your idea. Take note of the claims and specifications. You may find additional patents by referring to the patent examiner and the applicant.
6. Retrieve published patent applications with the CPC classification you picked in Step 3 from the Applications Full-Text and Image Database. It is also possible to use the same strategy of searching you used in step 4 to limit your search results to the most relevant patent applications by looking over the abstracts as well as the drawings on each page. Next, carefully examine the patent applications published and pay particular attention to the claims and additional drawings.
7. Find other US patents by keyword searching in PatFT or AppFT databases, searching for classification of non-U.S. patents as described below, and searching for non-patent patent disclosures in the literature of inventions using web search engines. 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.
