Definitions

  • the inner backup tool placed inside of the plug opening would have to be split in order to get inside of the plug opening while not dislodging the plug from its position within the container sidewall. Once the split backup tool is within the plug opening, it would have to expand to a diameter approximately equal to the inside diameter of the plug. This expansion of the inner split backup tool would create gaps between its segments thereby leaving areas of the plug and container sidewall which do not get clamped together and are not sealed. Therefore, a full 360-degree seal is not formed.
  • the present invention is directed to a method for producing a sealed plastic container that includes the steps of providing a container body having an end, providing a closure member having a skirt, inserting the closure member into the container body, heating the closure member skirt and container body end, and rolling the closure member skirt top and container end inward thereby fusing the closure member to the container body.
  • the present invention is also directed to a sealed plastic container that includes a sidewall having an open end configured for receiving a closure member and a closure member having a closure panel and an annular skirt extending therefrom.
  • the closure member is positioned inside of the sidewall such that the closure member annular skirt is adjacent the sidewall open end.
  • the closure member annular skirt and the sidewall open end are rolled inward and fused together to seal the sidewall open end.
  • FIG. 1 is an enlarged fragmentary sectional view showing the container body sidewall and closure member skirt rolled over thereby sealing an open end of the container in accordance with one embodiment of the present invention
  • FIG. 2 is an enlarged fragmentary sectional view of the closure member in accordance with one embodiment of the present invention.
  • FIG. 3 is an enlarged fragmentary sectional view showing a closure member positioned within the container body in accordance with one embodiment of the present invention
  • FIG. 4B is a front sectional view showing a closure member positioned within the container body in accordance with one embodiment of the present invention.
  • FIG. 4C is a front sectional view showing a heater head positioned to apply heated air to the closure member and container body in accordance with one embodiment of the present invention
  • FIG. 4E is a front sectional view of a container body with an open end sealed by a closure member in accordance with one embodiment of the present invention.
  • an embodiment of the present invention is directed to a sealed plastic closure 10 and the method for making it.
  • the sealed plastic closure 10 is generally comprised of a container body 12 having a sidewall 14 and a closure member or plug 30 .
  • the container body sidewall 14 and closure member 30 are rolled inward.
  • the container body 10 is comprised of a sidewall 14 having an interior surface 16 , an exterior surface 18 , and two ends 22 , 24 .
  • the two ends 22 , 24 and the sidewall 14 define a storage chamber 28 adapted for storing food products and the like.
  • both ends 22 , 24 may be open and suitable for being sealed in accordance with the present invention.
  • one end 24 may be closed by an end wall 26 .
  • the sidewall 14 is generally cylindrical both internally and externally. However, it is to be understood that other, non-round cross-sectional shapes can be utilized.
  • the sidewall 14 may be formed by extrusion, injection molding, or may be convolutedly wrapped and sealed to form an overlapping side seam.
  • the sidewall 14 is made of a polypropylene material having a material thickness on the order of about 0.015 to about 0.023 inches.
  • the material used to construct the sidewall 14 may also contain additives, such as calcium carbonate and polyethylene, to increase the sidewall's 14 flexibility characteristics.
  • the closure member 30 includes a panel or wall 32 and an annular skirt 34 extending generally perpendicular therefrom.
  • the annular skirt 34 has an interior surface 36 , an exterior surface 38 , and a top edge 40 . Proximate the top edge 40 , the annular skirt 34 has an area of reduced thickness forming a thin flange 42 .
  • the thin flange 42 circumscribes the entire periphery of the annular skirt 34 .
  • the thin flange 42 is provided to help facilitate the process of sealing the closure member 30 to the sidewall 14 as will be discussed further below.
  • the closure member wall 32 and an annular skirt 34 are generally cylindrical. Again, however, other, non-round cross-sectional shapes can be utilized.
  • the closure member 30 may be formed by extrusion or injection molding.
  • the closure member 30 is made of a polypropylene material having a material thickness on the order of about 0.035 inches.
  • the thickness of the thin flange 42 is preferably on the order of about 0.010 inches.
  • the material used to construct the closure member 30 may also contain additives, such as calcium carbonate and polyethylene, to increase the closure member's 30 flexibility characteristics.
  • a closure member 30 is inserted into the container body 12 , as shown in FIG. 4A .
  • the closure member 30 is oriented within the container body sidewall 14 such that its wall portion 32 is positioned within in the sidewall and its flange portion 42 is located proximate a sidewall end 22 .
  • the closure member top edge 40 is substantially flush with the end of the sidewall 14 .
  • the thin flange 42 and sidewall end 22 are heated.
  • the thin flange 42 and sidewall end 22 are heated through the application of heated air.
  • a heater head 46 having an air distribution manifold 48 is lowered about the sidewall 14 and closure member 30 .
  • the air distribution manifold 48 has horizontally oriented orifices (not shown) through which the heated air is distributed.
  • the orifices are positioned about the air distribution manifold 48 such that the heated air flows outward in a 360-degree pattern.
  • the air distribution manifold 48 is positioned at a level such that it is vertically centered about the closure member's thin flange portion 42 .
  • the air distribution manifold 48 is positioned such that its orifices will direct the heated air toward the thin flange 42 .
  • heated air at a temperature of approximately 370 to 390 degrees Fahrenheit, is applied to the thin flange 42 .
  • the heated air is applied for approximately five to seven seconds. It will be appreciated by one skilled in the art that the air temperature and duration for which the heated air is applied can be varied. For example, if warmer air is applied, the duration will be shorter. If cooler air is applied, the duration will be longer.
  • the closure member 30 is provided with a thin flange 42 so that the material of the closure member 30 will melt faster than the material of the sidewall 14 . As further described below, this helps facilitate the process of sealing the closure member 30 to the sidewall 14 . During the heating process, the closure member 30 and sidewall 14 begin to fuse together.
