Abstract
Description
- None.
- Methods of sealing plastic components together are widely used in the packaging industry. The current methods used to seal plastic components together include ultrasonic sealing and impulse sealing. Both ultrasonic sealing and impulse sealing require that two surfaces be clamped together in order for the sealing process to occur.
- The ultrasonic sealing and impulse sealing processes have limited application when used to seal the tops of containers where a full 360-degree seal is desired. Their limited application is due to the requirement that the two surfaces must be clamped together. In order to create a seal around the periphery of a container, a container closure member or plug would have to be clamped to the container sidewall continuously around the entire periphery of the container sidewall. In order to clamp a plug to the container sidewall, an inner backup tool would have to be placed inside of the plug opening and an outer clamping tool would have to be placed outside of the container sidewall.
- 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.
- Accordingly, a need exists for a method of sealing plastic containers in which a full 360-degree seal can be 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.
- Further features of the present invention will become apparent to those skilled in the art to which the present invention relates from reading the following description with reference to the accompanying drawings, in which:

For purposes of clarity in illustrating the characteristics of the present invention, proportional relationships of the elements have not necessarily been maintained in the drawing figures.
- An embodiment of the present invention is directed to a sealed
plastic closure 10 and the method for making it. As illustrated inFIG. 1 , the sealedplastic closure 10 is generally comprised of acontainer body 12 having asidewall 14 and a closure member orplug 30. In the sealing process, thecontainer body sidewall 14 andclosure member 30 are rolled inward. - The
container body 10 is comprised of asidewall 14 having aninterior surface 16, anexterior surface 18, and twoends ends sidewall 14 define astorage chamber 28 adapted for storing food products and the like. In one embodiment, bothends - In another embodiment, one
end 24 may be closed by anend wall 26. In one embodiment, thesidewall 14 is generally cylindrical both internally and externally. However, it is to be understood that other, non-round cross-sectional shapes can be utilized. Thesidewall 14 may be formed by extrusion, injection molding, or may be convolutedly wrapped and sealed to form an overlapping side seam. Preferably, thesidewall 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 thesidewall 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 orwall 32 and anannular skirt 34 extending generally perpendicular therefrom. Theannular skirt 34 has aninterior surface 36, anexterior surface 38, and atop edge 40. Proximate thetop edge 40, theannular skirt 34 has an area of reduced thickness forming athin flange 42. Thethin flange 42 circumscribes the entire periphery of theannular skirt 34. Thethin flange 42 is provided to help facilitate the process of sealing theclosure member 30 to thesidewall 14 as will be discussed further below. In one embodiment, theclosure member wall 32 and anannular skirt 34 are generally cylindrical. Again, however, other, non-round cross-sectional shapes can be utilized. Theclosure member 30 may be formed by extrusion or injection molding. Preferably, theclosure member 30 is made of a polypropylene material having a material thickness on the order of about 0.035 inches. The thickness of thethin flange 42 is preferably on the order of about 0.010 inches. The material used to construct theclosure member 30 may also contain additives, such as calcium carbonate and polyethylene, to increase the closure member's 30 flexibility characteristics. - In the method of making a sealed
plastic container 10, aclosure member 30 is inserted into thecontainer body 12, as shown inFIG. 4A . As illustrated inFIG. 4B , theclosure member 30 is oriented within thecontainer body sidewall 14 such that itswall portion 32 is positioned within in the sidewall and itsflange portion 42 is located proximate asidewall end 22. Preferably, the closure membertop edge 40 is substantially flush with the end of thesidewall 14. - Once the
closure member 30 is properly positioned within thesidewall 14, thethin flange 42 and sidewall end 22 are heated. In one embodiment, thethin flange 42 and sidewall end 22 are heated through the application of heated air. As shown inFIG. 4C , aheater head 46 having anair distribution manifold 48 is lowered about thesidewall 14 andclosure member 30. Theair distribution manifold 48 has horizontally oriented orifices (not shown) through which the heated air is distributed. The orifices are positioned about theair distribution manifold 48 such that the heated air flows outward in a 360-degree pattern. As shown, theair distribution manifold 48 is positioned at a level such that it is vertically centered about the closure member'sthin flange portion 42. Thus, theair distribution manifold 48 is positioned such that its orifices will direct the heated air toward thethin flange 42. Once theheater head 46 is in place, heated air, at a temperature of approximately 370 to 390 degrees Fahrenheit, is applied to thethin 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. - Through conduction, a portion of the heat that is applied to the closure member's
thin flange portion 42 transfers to theadjacent sidewall end 22. When the heated air is applied, thethin flange area 42 will begin to melt and theadjacent sidewall end 22 will soften, but not totally melt. In another embodiment, heated air is applied to thesidewall exterior surface 18 rather than theclosure member flange 42. In that embodiment, a portion of the heat applied to thesidewall 14 will transfer to theclosure member flange 42. As eluded above, theclosure member 30 is provided with athin flange 42 so that the material of theclosure member 30 will melt faster than the material of thesidewall 14. As further described below, this helps facilitate the process of sealing theclosure member 30 to thesidewall 14. During the heating process, theclosure member 30 andsidewall 14 begin to fuse together. - Once the
closure member 30 andsidewall 14 are heated, they are both rolled inward to create a seal. As illustrated inFIG. 4D , adie 50 is lowered onto theclosure member 30 andsidewall 14. Thedie 50 has a profile that facilitates the rolling of theclosure member flange 42 and thesidewall 14. As shown inFIG. 4D , the outermost portion of the die 50 is an inwardly slopingwall 52 circumscribing its entire periphery. The inwardly slopingwall 52 guides thecontainer body 12 andclosure member 30 assembly into alignment with thedie 50. At its uppermost portion, the inwardly slopingwall 52 terminates in aradius 54. When theradius 54 meets the top,outer edge 20 of the sidewall, thesidewall end 22 andclosure member flange 42 begin to roll inward. This inward rolling action continues until theclosure member flange 42 is rolled around and back onto itself like seen inFIG. 1 . During this rolling action, the molten material of theclosure member flange 42 and the softened material of thesidewall end 22 fuse together due to the relatively small size of theradius 54. This fusing creates a seal between theclosure member flange 42 and thesidewall end 22 that extends around their entire 360-degree periphery.FIG. 4E shows the resulting heat-sealed container that is formed in this process. - From the foregoing, it may be seen that the sealed plastic closure and the method for producing it is particularly well suited for the proposed usages thereof. Furthermore, since certain changes may be made in the above invention without departing from the scope hereof, it is intended that all matter contained in the above description or shown in the accompanying drawing be interpreted as illustrative and not in a limiting sense. It is also to be understood that the following claims are to cover certain generic and specific features described herein.
