Pull ring seal system for containers
Systems and methods for storing a liquid include a container including a body portion defining an internal chamber and at least one opening in communication with the internal chamber, and an insertable plug including a plug body with two rings attached to the plug body via hinges, the insertable plug configured to be inserted into the opening so that a portion of the plug body covers a lip of the opening to restrict access through the opening to the liquid contained in the internal chamber, wherein the hinges can be deformed to raise the two rings away from the plug body. An insertable plug for a container can include a cylindrical plug body, and two rings attached to the plug body by hinges, wherein the hinges can bend to orient the rings towards or away from the plug body.
1. A system for storing a liquid, comprising:
a container including a body portion defining an internal chamber and at least one opening in communication with the internal chamber; and
an insertable plug including a plug body with two rings attached to the plug body via hinges, each hinge attached to an outside surface of an outer circumference of the plug body at a single point, the insertable plug configured to be inserted into the opening so that a portion of the plug body covers a lip of the opening to restrict access through the opening to the internal chamber,
wherein the hinges can be deformed to raise the two rings away from the plug body.
2. The system of claim 1 , wherein the plug body is configured to form an interference fit when inserted into the opening.
3. The system of claim 1 , wherein the plug body is configured to form a press fit when inserted into the opening.
4. The system of claim 1 , wherein the opening is an access spout raised from a surface of the container, an outside surface of the access spout having threads.
5. The system of claim 4 , comprising a screw top with threads that mate with the threads of the access spout.
6. The system of claim 4 , wherein the plug body has at least one groove configured to receive an O-ring therein, the O-ring sealingly engaging with the access spout.
7. The system of claim 1 , wherein the insertable plug is configured to be removed from the opening and then re-inserted into the opening.
8. A method of assembling a container, comprising the steps of:
providing a container including a body portion defining an internal chamber and at least one opening in communication with the internal chamber; and
inserting an insertable plug including a plug body with two rings attached to the plug body via hinges, each hinge attached to an outside surface of an outer circumference of the plug body at a single point, the insertable plug configured to be inserted into the opening so that a portion of the plug body covers a lip of the opening to restrict access through the opening to the internal chamber,
wherein the hinges can be deformed to raise the two rings away from the plug body.
9. The method of claim 8 , wherein inserting the plug comprises forming an interference fit between the plug body and the opening.
10. The method of claim 8 , wherein inserting the plug comprises forming a press fit between the plug body and the opening.
11. The method of claim 8 , comprising attaching a screw top over the opening and the insertable plug.
