Description

Technical Field

[0001] The present invention relates to a beverage bottle for extracting cold brew (drip) beverages using water (cold water or normal temperature water), and particularly to a drip beverage bottle having a dual filter structure capable of accommodating both loose tea leaves and tea bags.

Background Art

[0002] In recent years, due to the health benefits of low caffeine, rich polyphenols, and non-alcohol, the demand for cold brew (drip) tea has been rapidly expanding both at home and abroad. In luxury hotels and high-class restaurants in Europe, the United States, and Asia, the demand for non-alcoholic beverages as paired beverages with course meals is strong, and the interest in drip Japanese tea has been increasing year by year. Most conventional drip bottles are only compatible with either a filter for loose tea leaves or a filter for tea bags, and there has been no structure that can selectively switch between both extraction forms in a single bottle. In addition, there has been no product that combines a high-class feel, durability, and hygiene that can withstand use in the food service industry (hotel and restaurant tables).

Summary of the Invention

Problems to be Solved by the Invention

[0003] The present invention has been made in view of the problems of the above prior art, and aims to solve the following problems.

[0004] First, to provide a general-purpose drip bottle that can accommodate both loose tea leaves and tea bags.

[0005] Second, to maximize the extraction efficiency by having a structure that allows the tea leaves to freely move in the internal space of the bottle when using loose tea leaves.

[0006] Thirdly, the objective is to provide a structure that securely holds the tea bag in place at the bottom when using it, preventing the tea bag from moving towards the body when pouring into a glass.

[0007] Fourthly, the structure allows all parts to be divided into three sections and individually disassembled for cleaning, thereby achieving a high level of hygiene for use in food service establishments.

[0008] Fifth, by having a shape and neck specifications similar to wine bottles, it blends naturally with wine bottles on tables in high-end restaurants and hotels, and allows for sealed storage with a wine cork stopper. [Means for solving the problem]

[0009] To solve the above problems, the cold-brew beverage bottle of this invention has three parts, an upper cap, a body, and a bottom, which are detachably connected to each other by a screw-type structure.

[0010] An upper filter is positioned at the joint between the upper cap and the body, which allows the liquid to pass through while retaining the loose tea leaves. The loose tea leaves can move freely within the internal space of the body below the upper filter, increasing the contact area with water and thus improving extraction efficiency.

[0011] A lower filter is positioned at the joint between the body and the bottom, which holds the tea bag in place within the bottom while allowing only liquid to pass through. This ensures that the tea bag is stably held within the bottom, resulting in smooth pouring without the tea bag moving into the body when pouring into a glass.

[0012] The dual filter structure allows for selective use of either the upper filter for extracting loose leaf tea or the lower filter for extracting tea bags. [Effects of the Invention]

[0013] According to this invention, the following effects can be obtained.

[0014] The dual filter structure allows a single bottle to handle both loose leaf tea and tea bag brewing methods, significantly improving user convenience.

[0015] When using loose leaf tea, the upper filter holds the tea leaves in place, allowing them to move freely within the internal space of the barrel. This maximizes the contact area between the tea leaves and water, improving extraction efficiency.

[0016] When using a tea bag, the lower filter holds the tea bag in place at the bottom, preventing it from popping out of the body when pouring into a glass, allowing for a clean and beautiful pour.

[0017] The design, which adds weight to the bottom 4, prevents the bottle from floating due to buoyancy even when the liquid content decreases while using the wine cooler, thus maintaining a stable state.

[0018] The three-part screw-joint structure allows for individual disassembly and cleaning of the top cap, body, and bottom parts, making hygiene management in food service settings easy.

[0019] By using impact-resistant and transparent synthetic resin for all parts, the color and condition of the liquid contents can be visually inspected without the risk of breakage associated with glass products, making it suitable for professional use.

[0020] Because it has a shape and neck standard similar to a wine bottle, it blends naturally with wine bottles when placed alongside them in a dining setting, and it can also be sealed and stored with a wine cork. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0022] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same reference numerals are assigned to the same components, and redundant descriptions are omitted.

[0023] As shown in FIGS. 1 and 2, the water-discharging beverage bottle 1 of the present invention has a three-piece screw-threaded structure composed of an upper cap 3, a body portion 2, and a bottom portion 4. The joints between the upper cap 3 and the body portion 2 and between the body portion 2 and the bottom portion 4 are detachably screwed by an inner screw structure, and a silicone packing 5 is arranged at each joint to prevent liquid leakage.

[0024] All parts of the upper cap 3, the body portion 2, and the bottom portion 4 are made of a synthetic resin having impact resistance and transparency. Specifically, Tritan resin (manufactured by Eastman Chemical Company) having food safety (US FDA certification), BPA-free, and dishwasher-compatible characteristics or a material having equivalent characteristics can be used.

[0025] The body portion 2 has a shape that gently widens downward from the shoulder, similar to the Burgundy type of a wine bottle, and the overall height is about 300 mm. The opening of the upper cap 3 has an inner diameter (Φ20 mm) conforming to the bottle mouth standard of a wine bottle, and a wine cork can be directly attached and stored in a sealed manner.

[0026] As shown in Figures 3 and 5, an upper filter 6 is positioned at the joint between the upper cap 3 and the body 2. The upper filter 6 has a structure that allows liquid to pass through while retaining loose tea leaves, and the loose tea leaves move freely within the internal space of the body 2 below the upper filter 6. This maximizes the contact area between the tea leaves and water, resulting in efficient extraction. After extracting the loose tea leaves, the bottle can be tilted and poured into a glass, and since the tea leaves are retained by the upper filter 6, only the liquid is dispensed.

[0027] As shown in Figures 4 and 6, a lower filter 7 is positioned at the joint between the body 2 and the bottom 4. The lower filter 7 has a structure that allows only liquid to pass through while locking the tea bag inside the bottom 4. By placing the tea bag on the lower filter 7 of the bottom 4 and screwing the bottom 4 into the body 2, the tea bag is held stably inside the bottom 4 during extraction. When pouring into a glass, only the liquid flows out while the tea bag remains locked inside the bottom 4, so the tea bag does not move into the body 2, allowing for clean pouring.

[0028] When using loose leaf tea, the user screws the upper cap 3, equipped with the upper filter 6, onto the body 2. When using a tea bag, the user places the tea bag on the bottom 4, equipped with the lower filter 7, and screws it onto the body 2. This dual filter structure, which allows for the selective use of the upper filter 6 and the lower filter 7, enables two different brewing methods with a single bottle. [Examples]

[0029] The following are specific embodiments of the present invention.

[0030] In this embodiment, the total height of the cold-brew beverage bottle 1 is approximately 302 mm, and the maximum outer diameter of the body 2 is 82 mm. The inner diameter of the opening of the upper cap 3 is 20 mm, which is a dimension conforming to the standard for wine bottle necks. The diameter of the threaded portion between the upper cap 3 and the body 2 is 56 mm, and leakage is prevented via a silicone gasket 5. The height of the bottom 4 is approximately 60 mm.

[0031] The upper filter 6 has a structure in which a conical mesh filter is attached to a mounting ring with a mounting diameter of 56 mm, and the material used is stainless steel mesh or nylon mesh. When loose tea leaves are placed in the upper filter 6 and the upper cap 3 is screwed onto the body 2, the tea leaves are extracted while freely moving around in the internal space of the body 2 (volume of approximately 106.6 cm3).

[0032] The lower filter 7 is a disc-shaped perforated plate structure that fits the inner diameter (Φ80mm) of the base 4 and is fixed to the inner bottom surface of the base 4. By placing the tea bag on the lower filter 7 and screwing the base 4 into the body 2, the tea bag is stably held inside the base 4 (volume approximately 83.7 cm3).

[0033] All parts are made of Tritan resin (manufactured by Eastman Chemical Company), which is dishwasher safe, BPA-free, and FDA-approved for food safety. The bottom section 4 is made of the same material but with glass fiber reinforcement, resulting in an opaque (black) finish that provides both stability and a premium feel when placed on a table. Furthermore, the bottom section 4 is intentionally designed with added weight so that even when the liquid content decreases during wine cooler use, the bottle will not float due to buoyancy and will remain stable. [Industrial applicability]

[0034] The cold-brew beverage bottle of this invention can be widely used in food and beverage establishments such as high-end restaurants, luxury hotels, and inns to serve non-alcoholic beverages as pairings with course meals. Furthermore, for home use, its convenience in accommodating both loose leaf tea and tea bags, along with its aesthetic appeal resembling a wine bottle, makes it a product that is expected to become widely popular for use at the dinner table. Furthermore, this method can be applied not only to cold-brewed tea, but also to the extraction of various cold-brew beverages such as cold-brew coffee, herbal water, and fruit-infused water, giving it industrial applicability across the entire beverage industry.
