Abstract
Description
Technical Field
[0001] This specification discloses a technology related to a beverage container with tea leaves.
Background Art
[0002] A tea bag is known as a product that can easily brew tea from tea leaves (see Patent Document 1). A tea bag is a bag body made of a material through which hot water can pass, with tea leaves enclosed therein. When brewing tea with a tea bag, after hot water is poured into a beverage container containing the tea bag, the tea bag is taken out from the beverage container at an arbitrary extraction state.

Summary of the Invention
Problems to be Solved by the Invention
[0004] When extracting tea from a tea bag multiple times, there is a problem that it is troublesome because the tea bag needs to be taken out and put into the beverage container many times.
Means for Solving the Problems
[0005] A beverage container with tea leaves according to one form disclosed in this specification includes a container body having a cylindrical shape with a side surface and a bottom surface, tea leaves, and a filter stretched inside the side surface and partitioning a space for accommodating the tea leaves between the inside of the bottom surface. The filter allows the passage of hot water and blocks the passage of the tea leaves. According to this form of beverage container with tea leaves, tea can be extracted from the tea leaves multiple times without taking in and out the tea leaves for each extraction. As a result, the hassle of taking in and out the tea leaves from the beverage container for each extraction can be eliminated.
Brief Description of the Drawings
[0006] [Figure 1] This is a cross-sectional view showing a beverage container. [Figure 2] This is a cross-sectional view showing a beverage container filled with hot or cold water. [Figure 3] This is a cross-sectional view showing a modified example of a beverage container. [Modes for carrying out the invention]
[0007] Figure 1 is a cross-sectional view showing a beverage container 100. The beverage container 100 is a beverage container with tea leaves 120. In addition to the tea leaves 120, the beverage container 100 includes a container body 110 and a filter 130.
[0008] The container body 110 of the beverage container 100 is cylindrical in shape, having sides 112 and a bottom 114. The container body 110 is made of paper. The container body 110 may also be made of synthetic resin. At least one of the outer and inner surfaces of the container body 110 may be laminated. The inner surface of the container body 110 may be provided with an aluminum foil layer.
[0009] The side surface 112 of the container body 110 is cylindrical. In this embodiment, the side surface 112 is shaped to form a part of the side surface of a cone. An opening 118 is formed at the upper end of the side surface 112. The side surface 112 may be constructed by overlapping multiple materials.
[0010] The bottom surface 114 of the container body 110 is a plate-shaped member that closes the lower end of the side surface 112. In this embodiment, the bottom surface 114 is disc-shaped.
[0011] The filter 130 of the beverage container 100 is stretched along the inside of the side 112. The filter 130 is a paper filter. The filter 130 may also be a nonwoven fabric filter. The filter 130 may also be a cloth filter made of natural fibers. The filter 130 may also be a cloth filter made of synthetic fibers.
[0012] The filter 130 partitions a space SP1 between itself and the opening 118. The filter 130 partitions a space SP2 for containing tea leaves 120 between itself and the inside of the bottom surface 114.
[0013] The tea leaves 120 in the beverage container 100 are dried plant products for brewing tea. The tea leaves 120 may be green tea, oolong tea, black tea, herbal tea, barley tea, etc. The tea leaves 120 are stored in space SP2.
[0014] Figure 2 is a cross-sectional view showing a beverage container 100 with hot water WT inside. When hot water WT is poured into space SP1, the filter 130 allows passage from space SP1 to space SP2. The filter 130 also allows hot water WT to pass from space SP2 to space SP1. The filter 130 prevents tea leaves 120 from passing from space SP2 to space SP1. Space SP2 is large enough to allow the water-soaked tea leaves 120 to move within the hot water WT.
[0015] Figure 3 is a cross-sectional view showing a modified example of a beverage container 100B. The beverage container 100B is the same as the beverage container 100, except that it is equipped with a removable lid 150 that covers the opening 118.
[0016] As described above, with the beverage containers 100 and 100B, tea can be extracted from the tea leaves 120 multiple times without having to remove and reinsert the tea leaves 120 each time. This eliminates the hassle of having to remove and reinsert the tea leaves 120 from the beverage container 100 each time.
[0017] The technology disclosed in this specification is not limited to the above-described embodiments, examples, and variations, and can be realized in various configurations without departing from the spirit thereof. For example, among the technical features in the above-described embodiments, examples, and variations, those corresponding to the technical features in each form described in the column of the outline of the invention can be appropriately replaced and combined in order to solve some or all of the above-described problems or to achieve some or all of the above-described effects. Also, technical features not described as essential in this specification can be appropriately deleted.
