INFUSION PACKAGE
An infusion device includes an infusion bag containing tea. A string is attached to the bag and a cover encloses the bag. The cover is perforated at the bottom to permit the user to remove the bag from the cover. The string is also attached to a detachable tab on the cover so that the bag can be drawn back up into the cover after brewing the tea.
1. Field of the Invention
The present invention relates to infusion packages for brewing beverages from dry beverage material.
2. Brief Description of the Prior Art
Combinations of infusion packages such as tea bags and covers or envelopes therefore are known in the art. For example, U.S. Pat. No. 3,175,911 discloses an infusion device for coffee or tea which includes a bag of fibrous filter material containing an infusible substance such as tea, a detachable tag, and a string extending between the detachable tag and the bag. In one embodiment, the tag is integrally formed with, but detachable from the bag. In another embodiment, the tag is integrally formed with an envelop for the bag. The tag is perforated to permit it to be placed over the spout of a teapot as a drop catcher. Similarly, U.S. Pat. No. 5,091,197 discloses a tea bag with a squeezing device. An infusion bag containing tea is connected by a string to a tag. The string extends through a plastic cover consisting of two panels connected along a fold line with a hole in the center of the fold line to permit the string to pass through. After the tea has been brewed, the tea bag can be pulled up into the cover and squeezed before discarding the bag.
SUMMARY OF THE INVENTIONThe present invention provides an infusion device including an infusion bag comprising a water permeable material enclosing a natural product material. A string is attached to the bag and to a cover for the infusion bag. The cover includes a first side and second side. The infusion bag is enclosed within the cover and extends between the first and second sides of the cover. The cover includes a release portion for permitting a user to release the infusion bag from the cover. In addition, the cover includes a tab portion detachable from the cover. When detached the tab portion forms tab, the remaining portion of the cover forming the body of the cover. The string is attached to the tab portion, and thus to the tab.
In a presently preferred embodiment, the cover is generally rectangular and has an upper edge and a lower edge. The cover is preferably perforated proximate the lower edge of the cover to permit a user to open the cover by tearing the cover along the perforations. Preferably, the tab portion extends from the upper edge of the cover and the cover is perforated proximate the tab portion to permit a user to separate the tab from the body of the cover by tearing the cover along the perforations.
Preferably, the cover is formed from a water-resistant material.
In order to use the infusion device, a user tears the cover along the perforations at the lower edge of the cover so that the bag can be withdrawn and placed in a suitable container for brewing, such as a teapot or cup of hot water. The bag is attached to the cover by the string, and the cover can be hung over the edge of the cup or teapot. After brewing is completed, the user detached the tab from the cover by tearing along the perforations at the top of the cover, and pulls the bag up into the cover by pulling on the string, which now extends through a hole in the upper edge of the cover formed when the user detached the tab from the cover. The bag can be squeezed by squeezing the cover to remove excess fluid, and the covered, used, bag can be discarded.
Referring now to the drawings, in which like reference numerals refer to like elements in each of the several views, there are shown schematically in
In order to use the infusion device 10, a user grasps the lower edge 38 of the cover 30 and tears the cover 20 along the perforation line 40 forming a stub 42 and a lower opening 46 in the bottom of the cover 30 through which the infusion bag 20 can be removed by the user.
After the brewing has been completed, the user grasps the cover body 34 and the tab portion 36 and tears the cover 30 along the upper perforated line 44 to separate the tab portion 36 from the body 34 of the cover 30, thus forming a second or upper hole 48 in the cover 30 through which the string 50 can freely pass, such as illustrated in the schematic side elevational view of
The user now grasps the tab or tab portion 36 and pull the string 50 through the lower opening 46 and upper opening 48 in the cover 30 until the wet infusion bag 30 is drawn up into the cover 30 through the lower opening 46, such as shown in the schematic side elevational view of
It will be apparent from the foregoing that various modifications may be made in the details of the infusion device of this invention, all within the spirit and scope of the invention as defined in the appended claims
Claims
1. An infusion device comprising:
- (a) an infusion bag comprising a water permeable material enclosing a natural product material;
- (b) a string attached to the bag; and
- (c) a cover for enclosing the infusion bag, the cover including a first side and second side, the infusion bag extending between the first and second sides of the cover, the cover including a release portion for permitting a user to release the infusion bag from the cover, the cover including a tab portion detachable from the cover to form a tab portion and a body of the cover, the string being attached to the tab portion.
2. An infusion device according to claim 1, the cover being generally rectangular and having an upper edge and a lower edge, the cover being perforated proximate the lower edge of the cover to permit a user to open the cover by tearing the cover along the perforations.
3. An infusion device according to claim 2, the tab portion extending from the upper edge of the cover, the cover being perforated proximate the tab portion to permit a user to separate the tab from the body of the cover by tearing the cover along the perforations.
4. An infusion device according to claim 1 wherein the cover is formed from a water-resistant material.
