Abstract

An easy open lid that comprises a top plate, a score line, a tongue, a rivet, a deboss, a tab, a top score line and a pull-strip. On the top plate there is a score line to surround the periphery of the tongue. But the score line does not close and remains open for a portion. Thus, an opening is formed when the tab is pulled for the tongue to rupture the score line. The open end of the tongue extends with a pull-strip that has a deboss. Similarly, there is a top score line to surround the periphery of the pull-strip. There is a tab on the top of the tongue and fixed by a rivet. When the tongue ruptures the score line to form an opening, the tab is pulled for the pull-strip to rupture the top score line.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The invention relates to an environment-friendly and user-friendly improved easy open lid.
  • 2. Description of the Prior Art
  • Easy open lid has been very popular globally. Typical easy open lids for beverage cans include Ring-Pull-Tab (RPT) type and Stay-On-Tab (SOT) type. The former type usually causes environment and recycle issues because the user litters the tab and the tongue after opening the beverage can. Therefore, developed countries very rarely use RPT type easy open lids. The latter type prevents environmental issues because the tab and the tongue stay on the top plate after the container is open and they are recyclable with the can. However, it fails to facilitate sales promotion because the tongue is pushed inside the can.
  • Currently the industry attempts to print promotional message by laser technology on the back side of the tab. This is still in experimental stage and there are many issues to resolve. For example, laser printing positioning accuracy cannot be assured in a mass production process. Thus, current SOT type easy open lids cannot be used for sales promotion. The Modified Stay on Tab (MSOT) in this invention is to overcome the above drawback and meet environmental requirements.
    • SUMMARY OF THE INVENTION
  • The objective for the invention is to design and provide an effective structure for easy open lids to solve the sales promotion issue with traditional SOT easy open lids and meet environment and recycle requirements.
  • To achieve the objective, the structure for the improved MSOT easy open lid in the invention comprises a top plate, a score line, a tongue, rivet, a deboss, a tab, a top score line and a pull-strip. The opening mechanism is lifting the tab and simultaneously rupturing the score line around the tongue, which is adopted by current SOT easy open lids. For revealing sales promotional message, the user lifts the tab further and pulls upward the pull-strip behind the tongue along the top score line. In this way, the sales promotion can be achieved because the printed message on the back side of the tongue can be easily seen.
  • The following will describe the structural characteristics, objective and benefits for the invention through illustration of an embodiment.
    • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is the top view diagram for the improved easy open lid for the invention, showing the pull-strip and the top score line in the basic structure of the invention.
  • FIG. 2 is an illustration that the tab ruptures the tongue and keeps the tongue inside the can.
  • FIG. 3 is an embodiment for the improved easy open lid for the invention that shows for sales promotion the opened tab can be further pulled backward to expose the tongue and the pull-strip out of the can.
    •  DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The easy open lids for the invention, as shown in FIG. 1, mainly comprises a top plate (1), a score line (2), a tongue (3), a rivet (4), a deboss (5), a tab (6), a top score line (7) and pull-strip (8).
  • On the top plate (1) there is a score line (2). The score line (2) surrounds the periphery of the tongue (3). But the score line (2) does not close and remains open for a portion to prevent the fall of the tongue (3) into the can after opening. The open end of the tongue (3) extends with a pull-strip (8) that has a deboss (5). Similarly, there is a top score line (7) to surround the periphery of the pull-strip (8), but not to close itself There is a tab (6) on the top of the tongue (3) and fixed by a rivet (4).
  • For opening, the space reserved by the deboss (5) facilitates the lifting of the tab (6), which allows the nose of the tab (6) to press the tongue (3) and the tongue (3) to detach from the top plate (1) along the score line (2), to form an opening hole that enables the flow of the content out of the can.
  • Please refer to FIG. 2 for the status illustration after opening. The tongue (3) is heading towards inside the can. The tab (6) is attached to the top plate (1) through the rivet (4) on the pull-strip (8). For sales promotion, after the tongue (3) is opened, the tab (6) can be lifted upward and pulled backward further to open up the pull-strip (8) along the top score line (7). FIG. 3 is a status illustration when the pull-strip (8) is opened up.
  • Please refer to FIG. 2 and FIG. 3. For the improved easy open lids in the invention, the opening mechanism is lifting the tab (6) and simultaneously rupturing the score line (2) around the tongue (3), which is adopted by current SOT easy open lids. For revealing sales promotional message, the user lifts the tab (6) further and pulls upward the pull-strip (8) behind the tongue along the top score line (7). In this way, the sales promotion can be achieved because the printed message on the back side of the tongue (3) can be easily seen. Moreover, the tongue (3) is connected to the top plate (1) through the pull-strip (8), so it is impossible to lose any parts.
  • In summary, the “MSOT” easy open lids not only solve the promotional printing issue with the traditional products by providing further lifting mechanism to reveal the promotional message printed on the back side of the tongue, but also meet the environment and recycle requirements by preventing the littering with tabs. The design is an innovation that cannot be found in publications and an application for patent is filed because this invention shall meet the patent application requirements.
  • However, the above description is only for preferred embodiments and it is emphasized hereafter that those structurally equivalent modifications based on the description and illustration for the invention shall be covered by the claims of the invention.
