Definitions

• the present invention relates to tea bag packages. More specifically, the invention relates to a tea bag package for (1) storing a tea bag and (2) squeezing excess liquid from the tea bag after infusion.
• U.S. Patent No. 3,057,729 to Grant discloses a tea bag package including a string attaching a tea bag to a tab, and a pair of front and rear panels hingedly connected along their top edges and moveable along the string. After infusion, the flap can be pushed down the string so that the two flaps engage the tea bag for squeezing excess liquid from the bag.
• U.S. Patent No. 3,550,528 to O'Neill discloses a tea bag squeezer and holder including a pair of front and rear panels hingedly connected along their top edges, connected along their side edges by triangular bellows-folded gussets, and an inner liner secured to the inner faces of the panels. the bottom of the holder is open.
• U.S. Patent No. 4,726,956 to Christie discloses a tea bag cover comprising a pair of front and rear panels hingedly connected along their top edges, one of the panels being stapled to a tea bag. During use, the tea bag can be suspended on the side of a mug by one panel and excess liquid can be squeezed out of the tea bag by pressing the tea bag against the side of the mug with the other panel.
• U.S. Patent No. 3,092,242 to Irmscher discloses a tea bag squeezer including a pair of panels hingedly connected at their top edges and moveable along a string connecting the tea bag to a tab. The panels can be moved along the string to engage the tea bag and squeeze excess water therefrom.
• U.S. Patent No. 2,986,269 to Goldberg discloses a tea bag package comprising a flexible, hollow cone moveable along a string that connects a tea bag to a tab. Prior to use, the tea bag can be stored in the cone and the tab can be tucked into a pocket in the cone. After infusion, the cone can be moved to engage the tea bag and squeeze excess liquid therefrom.
• U.S. Patent No. 2,308,241 to Hogaboom discloses a pair of panels hingedly connected at their top edge, a perforated removable tab formed at the top edge of the panels, and a string connecting a tea bag to the removable tab. After infusion, the tab is removed from the panels and the panels are moved along the string to engage the tea bag and squeeze excess liquid therefrom.
• the brewmaster In the above prior art tea bag packages, the brewmaster must struggle with three separate components during infusion: a tea bag, a tab, and an envelope/squeezer. The brewmaster must maneuver these three components during infusion whether or not he wishes to employ the envelope to squeeze excess liquid from the tea bag. Also, the prior art packages are not completely sealed during storage of the tea bag and are not adequately sealed during squeezing to prevent leakage and dripping of .liquid from the sides of the tea bag and package. Rather, the prior art tea bag packages are incompletely sealed during storage of the tea bag, thereby preventing sanitary storage of the tea bag prior to use. Further, the prior art packages are only connected along their top edges during squeezing and do not extend beyond the outer periphery of the tea bag, thereby allowing liquid to leak or drip from the sides of the package during squeezing of the tea bag.
• a tea bag package where the brewmaster only has maneuver two components during infusion, the tea bag and the envelope, and if the brewmaster wishes to employ the squeezer element, a third component, a tab, is introduced after infusion by removing the tab from the envelope. It is also desirable to provide a tea bag package that is completely sealed prior to use to provide sanitary storage of the tea bag. Further, it is desirable to provide a tea bag package having sealed sides or sides that protrude outwardly from the outer periphery of the tea bag so that the package envelops the tea bag during squeezing to prevent liquid from leaking or dripping from the sides of the package and to hide the unsightly tea bag from view.
• the inventive tea bag package provides a package that is completely sealed prior to use for housing and storing a tea bag in a sanitary manner.
• the sides of the inventive package either remain sealed or extend outwardly from the tea bag's outer periphery, so that after infusion the package can be used to envelop the tea bag and squeeze excess liquid therefrom while preventing liquid from leaking or dripping from the sides of the package.
• the inventive tea bag package comprises an envelope having a top sealed by a top flap, a sealed bottom, and opening means, such as a string, for opening the bottom of the envelope to allow the tea bag housed therein to fall from the envelope.
• the top of the envelope includes a removable tab connected to the tea bag by connecting means. When the tab is removed from the envelope and pulled upward, the tea bag can be drawn back into the envelope after infusion to completely envelop the tea bag and squeeze excess liquid therefrom, if desired.
• the opening means comprises an adhesive tear strip.
• the sides and bottom of the envelope are sealed by a tear strip.
• the envelope sides are unsealed during squeezing and extend outwardly from the outer periphery of the tea bag to adequately cover the tea bag during squeezing and prevent leakage or dripping from the envelope.
• the sides of the envelope are pleated to provide more room to draw the tea bag back into the envelope after infusion.
• the top flap of the envelope serves as the removable tab.
• the package comprises a conical envelope having a sealed bottom and a removable top connected to the tea bag connecting means.
• the package includes an envelope having overlapping top and bottom flaps.
• the bottom flap is removed to open the bottom of the envelope and allow the tea bag to fall therefrom, and the top flap can be removed after infusion to allow the brewmaster to draw the tea bag back into the envelope and squeeze excess liquid therefrom, if desired.
