  • Publication number: 20090258114
    Abstract: A method of brewing a fresh, hot beverage in a beverage brewer (10) having a brew basket (18) for holding ingredient to be brewed and a dispensing spray head (12) for passing water onto a top surface of a layer of ingredient supported within the brew basket (18) during a dispense period of a brew cycle uses a temperature selectable dispense system having an on-demand hot water heating chamber assembly (30) with a hot water chamber (86) having a volume substantially less than the volume of beverage brewed during a single brew cycle. An electrical heating element (98) of sufficient power quickly and substantially alters the temperature of the water in the chamber during a single brew cycle and a microprocessor controller (38) for controlling the heating element in response to temperature sensors (40, 42) to control the heating element (98) to selectively change the temperature of the hot water dispensed to the brew basket (18) during a single brew cycle.

  • Patent number: 7152520
    Abstract: A tea bag press and container assembly configured for receiving a tea bag during or after brewing, which conceals the wet tea bag, collects dripping liquid, and extracts tea liquid essence by efficiently compressing the wet tea bag vertically or sidewardly. In a vertical compression embodiment, a lid has an integral press element that compresses the tea bag against a tea bag support means in the bottom of the container upon applying pressure to the lid. In a sideward compression embodiment, a flexible container retains the tea bag during sideward compression, such as between the thumb and fingers, for releasing tea liquid from the bag. The tea bag press-container assembly is designed to reduce staining and mess on saucers, tables and fabric caused by a dripping tea bag and provides efficient extraction and pouring of tea liquid into an existing beverage, or the brewing of an additional beverage.

    Abstract: The invention disclosed herein provides a way to engage a used concentrate packet such as a tea bag in a drink container in which a liquid product was made from the concentrate without removing the packet from the container and without having to directly contact the packet. Thus, one need not wet his or her fingers or anything in the area of the container, and the used packet when engaged will not interfere with drinking of the liquid product. The packet is also isolated from the interior of the drink container to inhibit further infusion or dissolving of any concentrate remaining in the packet, thereby to control the strength or concentration of the liquid product without having to remove the packet from the container. In the preferred embodiment the holder defines a compartment into which the used packet may be moved to isolate the packet from the interior of the drink container so as to inhibit further concentrating the liquid product from any concentrate in the packet.

  • Patent number: 5460844
    Abstract: A travelling two-ply web of infusion packages (11) is cut transversely by rotary cutting device (50) to form individual packages (1) which are attached to a styrene cover web (70). The packages 91) and web (70) are fed at the same speed rotary attachment device (100) comprising heated welding tips (102) cooperating with an anvil roller (90). The web (70) is fed to the attachment device at constant speed, but the packages (1) are accelerated up to the speed of the web (70) by accelerating rollers (62, 63) which grip the sealed edges of the packages. This introduces the necessary gap between successive packages. A hinge line (5) is produced in the web (70) by hinging device which facilitates folding of the cover and the package when the web carrying attached packages is cut into individual lengths.

  • Patent number: 5441752
    Abstract: The present invention is a beverage device. The beverage device comprises a beverage pack for adding flavor to a liquid, such as water. The beverage pack can be a tea bag but is not limited thereto. For instance, the beverage pack can also have coffee or mulling spices, as examples. The beverage device also comprises shield means for encapsulating the beverage pack within a bottom of a cup. The shield means is preferably connected to the beverage pack with a string. In one embodiment the shield means is collapsible from an open orientation to a closed orientation. In the open orientation the shield means provides flow channels for allowing the beverage pack to steep. In the closed orientation the flow channels are closed. Preferably the shield means comprises a first portion and a second portion. The first portion is slidably connected to the second portion to allow the shield means to be moved from the open orientation to closed orientation.

  • Patent number: 5399224
    Abstract: Tags and thread are assembled together for the manufacture of tagged articles such as infusion packets in which each tag is attached to the packet by a length of thread. The thread is held in a looped form between the tag and the packet before use. For the assembly of the tags and thread and to increase the length of thread attaching each tag, means are provided for forming a doubled-over loop that can be trapped between the tag and the packet.

  • Patent number: 5366741
    Abstract: A dual compartment infusion packet has the compartments directly secured to each other at one end of the packet and separated by a V-fold of the packet material at the other end. A suspension thread has an intermediate portion lying within the fold and end portions extending therefrom through attachment means at the other end of the packet. The end portions are displaceable in the attachment means so that when tensioned they contract the packet to squeeze out liquid held in the packet after an infusion process.

  • Patent number: 4913916
    Abstract: Disclosed is a beverage infusion device including a percolator within a gas-liquid chamber permeable to air and water containing an infusible, insoluble dry beverage substance such as coffee particles. When the beverage infusion device is repeatedly immersed in and removed from water, water enters into the gas-liquid chamber through the percolator at a point above the coffee particles, drains over and through the coffee particles and out of the gas-liquid chamber. A disposable, miniature percolator for brewing a single cup or limited number of cups of a hot beverage such as coffee is thus provided.

  • Patent number: 4826695
    Abstract: A beverage infusion device for preparing a beverage such as coffee includes a gas-liquid chamber permeable to air and water which contains an infusible, insoluble dry beverage substance containing edible, soluble food solids, such as coffee particles, and a carbon dioxide source which releases carbon dioxide when immersed in liquid, such as water. When the infusion device is immersed in water, the carbon dioxide source, preferably situated beneath the coffee particles, releases carbon dioxide. The carbon dioxide bubbles up through the coffee particles, momentarily suspending and agitating the coffee particles. Maximum contact between water and coffee particles is achieved and the edible, soluble food solids are quickly extracted from the coffee particles to form a hot beverage.Also disclosed is a beverage infusion device including a percolator within a gas-liquid chamber permeable to air and water containing an indusible, insoluble dry beverage substance such as coffee particles.
