Abstract
Description
Technical Field
[0001] This application relates to the field of beverage bottles, and more particularly to a sealing structure for a beverage bottle and a beverage bottle. Background Technology
[0002] In the field of cold brew tea, in order to maintain the taste and flavor of cold brew tea, existing cold brew tea uses an external method for preservation and transportation. When cold brewing is required, tea bags or powders are placed in beverage bottles for easy cold brewing.
[0003] Currently, there are two methods for storing tea or powder during transportation. One method is to create a cavity inside the bottle cap and seal it to store the tea bag or powder, thus preventing the liquid inside the beverage bottle from coming into contact with the tea bag or powder and thus preventing the tea bag or powder from spoiling.
[0004] Another method involves creating an external cavity on the outside of the bottle cap, then sealing it with a resealable cap. This sealing method often uses a single-layer seal, where the bottle cap and the resealable cap are locked together by a threaded connection to seal the external cavity and prevent external liquids from entering. However, this threaded connection between the bottle cap and the resealable cap results in poor sealing. During transportation, if the external environment is very humid, moisture may enter the external cavity through the threaded connection, contaminating the tea bags or powder inside and rendering them unusable.

[0048] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0049] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component. The terms "top," "bottom," "upper," "lower," "left," "right," "front," "back," and similar expressions used in this article are for illustrative purposes only.
[0050] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0051] Embodiments of this application provide a sealing structure 100 for a beverage bottle, comprising:
[0052] The cap 110 is fitted onto the bottle body 161 at one end;
[0053] The receiving member 120 has a slot 120a at one end and a retaining ring 121 protruding outward at the other end. A sealing groove 121a is formed inside the retaining ring 121. The cover 110 engages with the slot 120a.
[0054] A sealing cap 170 is disposed on the side of the receiving member 120 away from the cover body 110 and covers the sealing groove 121a;
[0055] The placement ring 130 has a placement groove 130a inside, which is provided on the receiving member 120 or the sealing cover 170. The placement groove 130a is used to place the brewing material.
[0056] The accommodating member 120 covers the sealing cover 170 so that the placement ring 130 is located in the sealing groove 121a, thereby sealing the placement groove 130a and the sealing groove 121a.
[0057] Please refer to Figures 1-8 In this embodiment, one end of the cap 110 is threaded or snapped onto the bottle body 161 of the beverage bottle 160, which serves to seal the bottle opening and ensure that the beverage bottle 160 is completely sealed.
[0058] The receiving member 120 has a slot 120a at one end, and engages with the cover 110 through the slot 120a to achieve stable fixation inside the cover 110.
[0059] The other end of the receiving member 120 extends outward to form a fixing ring 121, and a sealing groove 121a is provided inside the fixing ring 121.
[0060] The sealing cap 170 is placed on the end of the receiving member 120 away from the cover body 110, and the sealing cap 170 covers the sealing groove 121a to form a closed sealing space.
[0061] The placement ring 130 has a placement groove 130a inside, which is used to place tea bags, tea powder or other brewing materials for cold brewing tea.
[0062] The placement ring 130 is disposed on the receiving member 120 or the sealing cover 170. After the receiving member 120 and the sealing cover 170 are engaged, the placement ring 130 is just embedded in the sealing groove 121a, so that both the fixing ring 121 and the placement ring 130 form a seal between the receiving member 120 and the sealing cover 170, thereby achieving a double-layer sealing effect and completely avoiding the influence of thread gaps on the sealing performance, resulting in a better sealing effect.
[0063] The first layer of sealing is achieved through the structural cooperation between the fixing ring 121 and the sealing cap 170, while the second layer of sealing is achieved by the placement ring 130 being embedded in the sealing groove 121a, thus achieving an internal seal. The two layers of structure are independent yet complementary, forming a double-layered seal for the brewed beverage. Even if the external environment is humid, moisture can hardly penetrate the double physical barrier, significantly reducing the risk of the brewed beverage becoming damp and spoiling.
[0064] It should be noted that the cap 110 is roughly circular in shape, with one end recessed inward and covering the bottle 161, and the other end engaged in the slot 120a of the accommodating member 120, thereby fixing the accommodating member 120.
[0065] The receiving member 120 is generally cylindrical in shape and has slots at both ends. One end is recessed inward to form a circular groove 120a (which can be changed according to the shape of the cover 110 in other embodiments) for locking the cover 110. The other end is recessed inward to form a sealing groove 121a, and its protruding part forms a retaining ring 121.
[0066] The sealing cap 170 is generally circular in shape, with one end recessed inward. The recessed side is threadedly connected to the retaining ring 121 of the receiving member 120 to cover the sealing groove 121a.
[0067] The placement ring 130 is roughly a round tube with open ends, and an open space in the middle—the placement slot 130a—is used to place brewing materials, such as tea leaves, tea bags, coffee powder, milk tea powder, etc.
[0068] In at least one embodiment of this application, the height of the placement ring 130 is denoted as a, the height of the fixing ring 121 is denoted as b, and when the sealing cover 170 is closed with the receiving member 120, the distance from the bottom wall of the sealing groove 121a to the bottom wall of the sealing cover 170 is denoted as c, satisfying the relationship: a = b = c.
[0069] Please refer to Figures 1-8 In this embodiment, since a=b=c, after the accommodating member 120 and the sealing cover 170 are closed, the fixing ring 121 and the sealing cover 170 fit together tightly. The placement ring 130 is pressed against the sealing cover 170 and the accommodating member 120, forming a sealed connection. This achieves multi-point contact and circumferential sealing, preventing moisture from entering the placement tank 130a, thereby protecting the brewing materials in the placement tank 130a.
[0070] Ensure that the retaining ring 121 and the placing ring 130 are completely filled in the sealing space, achieving precise compression and double sealing without causing compression deformation.
[0071] In at least one embodiment of this application, the placement ring 130 is disposed in the sealing groove 121a and is fixedly connected to the bottom wall of the sealing groove 121a. The placement groove 130a is formed between the placement ring 130 and the bottom wall of the sealing groove 121a, and the fixing ring 121 is coaxially arranged with the placement ring 130.
[0072] Please refer to Figures 1-8 In this embodiment, the placement ring 130 is directly fixed inside the sealing groove 121a by integral forming. The sealing groove 121a is formed by the internal space of the fixing ring 121 on the accommodating member 120, and its bottom is the bottom wall of the sealing groove 121a.
[0073] The placement ring 130 is directly set inside the sealing groove 121a and fixedly connected to the bottom wall of the sealing groove 121a. The body of the placement ring 130 extends upward from the bottom wall, and a placement groove 130a is formed between the placement ring 130 and the bottom wall of the sealing groove 121a. The placement groove 130a is used to store tea bags, powders and other brewing materials.
[0074] The fixing ring 121 and the placement ring 130 share a central axis, ensuring structural symmetry and precise fitting. This allows the sealing cover 170 to be precisely pressed onto the placement ring 130 when it is fastened, achieving structural compression and sealing.
[0075] When the sealing cap 170 is closed with the receiving part 120, the retaining ring 121 abuts against the sealing cap 170, and at the same time the placement ring 130 abuts against the sealing cap 170, achieving a double seal and avoiding the problem of poor sealing caused by threaded connection. Especially in humid transportation environment, it can effectively prevent water vapor from penetrating.
[0076] It should be further explained that when the placement ring 130 is placed in the sealing groove 121a, during the production process, after the tea leaves or powder are placed in the placement groove 130a, a layer of plastic film or aluminum film can be covered on the placement ring 130 and the fixing ring 121 to further seal them and make the sealing effect better. The plastic film completely seals the sealing groove 121a and the placement groove 130a, so that the sealing groove 121a and the placement groove 130a form a closed space to prevent moisture from entering.
[0077] Meanwhile, the placement ring 130 is connected to the bottom wall of the sealing groove 121a to form a ring-shaped reinforcing structure, which has good resistance to deformation. Even if the outer sealing cover 170 is under pressure, the pressure can be evenly transmitted to the bottom of the entire sealing groove 121a, and the internal structure is not easily damaged by point pressure.
[0078] In at least one embodiment of this application, the placement ring 130 is disposed on the bottom wall of the sealing cover 170, and the placement ring 130 and the bottom wall of the sealing cover 170 surround to form the placement groove 130a.
[0079] Please refer to Figures 1-8 In this embodiment, the placement ring 130 is integrally formed on the bottom wall of the sealing cover 170 (i.e., the inner side of the sealing cover 170, the side facing the receiving member 120), and the placement ring 130 extends vertically downward from the bottom wall of the sealing cover 170.
[0080] The placement ring 130 is arranged in a ring around a local area of the bottom wall of the sealing cap 170. The placement ring 130 and the bottom wall of the sealing cap 170 together form a placement groove 130a, which is used to store brewing materials (such as tea bags or powders).
[0081] During assembly, the sealing cap 170 and the receiving part 120 are connected by threads or snapped together, and the placement ring 130 is inserted into the sealing groove 121a in the receiving part 120. Without changing the internal structure of the receiving part 120, the placement ring 130 and the sealing groove 121a can still be nested together to form a seal.
[0082] At this time, the placement ring 130 of the sealing cap 170 abuts against the bottom wall of the sealing groove 121a of the accommodating member 120, and the fixing ring 121 of the accommodating member 120 abuts against the bottom wall of the sealing cap 170, forming a double seal. The placement ring 130 is located inside the sealing groove 121a, which allows the brewing material inside the placement groove 130a to be better sealed, preventing external moisture from entering the placement groove 130a, so as to ensure that the brewing material can be stored for a long time and maintain its integrity in various environments.
[0083] In at least one embodiment of this application, the sealing structure 100 of the beverage bottle further includes:
[0084] A fixing ring 140 is installed on the placement ring 130 and is located at the opening of the placement ring 130. The fixing ring 140 has an installation opening 140a.
[0085] The tilting guide 150 is fixed at one end to the fixing ring 140 and at the other end to the bottom wall of the placement groove 130a. The tilting guide 150 forms a tilting cavity 150a inside, and the brewing material is contained in the tilting cavity 150a.
[0086] Please refer to Figures 1-8 In this embodiment, the fixing ring 140 is installed at the opening of the placement ring 130, that is, at the outermost edge of the brewing material placement groove 130a. The fixing ring 140 is provided with an installation port 140a for installing and connecting the pouring guide 150. One end of the pouring guide 150 is connected to the fixing ring 140, and the other end is connected to the bottom wall of the placement groove 130a. The brewing material (such as tea bags or powder) is placed in the pouring chamber 150a.
[0087] Initial state: Sealed storage. The brewing material (such as tea bags or powder) is pre-filled into the pouring chamber 150a of the pouring guide 150. Both ends of the pouring guide 150 are fixed to the bottom wall of the placement groove 130a and the fixing ring 140, respectively. The whole is in a closed structure between the sealing cover 170 and the receiving part 120. The sealing cover 170 covers the top of the placement groove 130a, sealing the brewing material and preventing it from contacting air or liquid in advance to avoid deterioration.
[0088] Before use, the user removes the container 120 from the cap 110, opens the cap 110 (i.e. opens the bottle mouth of the beverage bottle 160), and then opens the sealing cap 170 to fully expose the placement slot 130a, allowing the brewing material to be released.
[0089] The user inverts the container 120 and aligns it with the mouth of the beverage bottle 160, then pours the beverage. Under the guidance of the pouring guide 150, the beverage enters the bottle 161 stably along the preset trajectory of the pouring chamber 150a. The entire flow of the beverage is controllable and directional, and will not scatter or spill onto the outside of the bottle 161 or onto the user's hand.
[0090] The pouring guide 150, with its enclosed structure and directional opening, allows the brewed ingredients to smoothly enter the bottle along a predetermined path during use, preventing uncontrolled spillage and significantly improving cleanliness and convenience.
[0091] It should be noted that the fixing ring 140 is roughly a circular plate and is fixed to the opening of the placement ring 130 by adhesive or other fixing methods. The tilting guide 150 is roughly a frustum-shaped circular structure and is roughly a bushing, made of flexible materials such as cotton, plastic, or PP.
[0092] In at least one embodiment of this application, the tilting guide 150 has a large end 151 and a small end 152, the large end 151 being fixed to the bottom wall of the placement groove 130a, and the small end 152 being fixed to the fixing ring 140.
[0093] Please refer to Figures 1-8 In this embodiment, the pouring guide 150 has a cone-shaped structure, smaller at the top and larger at the bottom, within the placement ring 130, resembling a funnel. The larger end 151 is installed on the bottom wall of the placement groove 130a (i.e., the bottom of the brewing material storage cavity) and serves as the sealing end of the pouring guide 150. The smaller end 152 is connected to the fixing ring 140 and is located at the opening of the placement groove 130a (near the outlet side), serving as the brewing material pouring end. The pouring guide 150 gradually contracts from bottom to top within the placement groove 130a to form a flow guiding cavity.
[0094] When in use, the user opens the sealing cap 170 and pours the contents into the bottle mouth by aligning the container 120 with the bottle opening. Under the guidance of gravity and the contraction shape of the guide cavity, the brewed material flows from the large end 151 to the small end 152, and then falls precisely into the bottle body 161 through the mounting port 140a at the fixing ring 140. The whole process is completed along the inside of the guide cavity, making it less prone to side leakage or scattering.
[0095] The conical structure (from the large end 151 to the small end 152) conforms to the characteristics of gravity flow, can naturally converge, and achieves precise dispensing through structural guidance, effectively avoiding problems such as powder scattering or tea bag displacement.
[0096] The flow channel is narrow but the transition is smooth, preventing granular or broken tea from accumulating or getting stuck at the outlet, ensuring a smooth pouring process.
[0097] The pouring guide 150 provides a closed downward channel to prevent users from pouring tea bags or powder directly into the bottle opening, thus avoiding splashing and spilling, and keeping the bottle opening, hands and the external environment clean and tidy.
[0098] Both the large end 151 and the small end 152 can be glued together. In another embodiment, the tilting guide 150 can adopt a structure similar to a conical bottle.
[0099] In at least one embodiment of this application, the diameter of the large end 151 is denoted as d and the diameter of the small end 152 is denoted as e, satisfying the relationship d > e > 0.
[0100] Please refer to Figures 1-8 In this embodiment, the following condition is satisfied: 2e≥d>e>0, that is, the pouring guide 150 has a tapered channel structure that gradually narrows from bottom to top. The brewing material is initially sealed in the pouring chamber 150a inside the guide. When in use, the sealing cap 170 is opened and the container 120 is aligned with the bottle mouth. The user pours the container 120. Under the action of gravity, the brewing material starts to flow from the large end 151, gradually converges to the small end 152, and finally passes through the outlet of the small end 152 and is accurately introduced into the bottle body 161 through the installation port 140a of the fixing ring 140.
[0101] Through the conical structure and the guidance of gravity and the effect of contraction and convergence, the brewed material is allowed to slide naturally down from the large opening and be precisely discharged through the small opening, resulting in a continuous, smooth and concentrated flow path.
[0102] The tapered shrinkage design effectively prevents material from accumulating at the outlet, reduces the probability of clogging, and ensures that all the contents are poured out at once. When the user inverts the container 120, the brewed material will flow out in a bundle due to the shrinkage of the flow path, and will not scatter or stick to the edge of the bottle 161.
[0103] Secondly, the sealing design of this structure is more conducive to preventing water vapor and pollution.
[0104] In at least one embodiment of this application, the large end 151 gradually shrinks towards the small end 152 to form a tilting guide surface 150b, and the tilting guide surface 150b and the axis of the placement ring 130 make an angle α, where 0 < α ≤ 15°.
[0105] Please refer to Figures 1-8 In this embodiment, the tilting guide 150 gradually tapers upward from the lower large end 151, and the inner contour surface is the tilting guide surface 150b. The tilting guide surface 150b is a tapered shape with a certain included angle α relative to the axis (usually the vertical direction) of the placement ring 130. The included angle between the tilting guide surface 150b and the axis is α, which satisfies: 0 < α ≤ 15°, that is, the tilting guide surface 150b is a gradually tapering cone angle.
[0106] When the user opens the sealing cap 170 and tilts the container 120, the brewed material slides down the tilting guide surface 150b under the action of gravity. Since the α angle is small and the tilting guide surface 150b is a gently tilting curved surface, it can form a continuous and stable guiding path, accurately guiding the brewed material into the bottle 161, controlling the material sliding speed and path, which is especially suitable for easily spilled materials such as powder and tea.
[0107] When α is in the range of 0 to 15°, a stable and smooth conical flow path can be formed, avoiding the stagnation or accumulation of particles on the inner wall of the guide cavity.
[0108] During use, users can observe that the brewed substance slides naturally along the inner wall and is accurately introduced into the bottle. If the angle is too large (>15°), the guide path is short and the brewed substance may splash out of the guide outlet. If the angle is too small (close to 0°), the guide surface is close to vertical and the flow is not smooth.
[0109] In at least one embodiment of this application, the receiving member 120 is provided with a locking protrusion 122, the locking protrusion 122 is provided on the peripheral wall of the slot 120a, and the locking protrusion 122 engages with the cover 110.
[0110] Please refer to Figures 1-8 In this embodiment, a locking protrusion 122 is provided on the peripheral wall of the slot 120a of the accommodating member 120. The protrusion is a convex structure and is a long strip of semi-cylindrical shape. The outer peripheral wall of the cover 110 engages with the locking protrusion 122 to fix it.
[0111] When the cover 110 is inserted into the receiving member 120, the engaging protrusion 122 engages with the cover 110, thereby fixing the receiving member 120 onto the cover 110. Due to the engagement of the engaging protrusion 122, it can be matched with cover 110 of different diameters. The engaging protrusion 122 is made of elastic material or rigid material. When it is made of elastic material, the degree of deformation of the engagement is greater, which can be applied to cover 110 of different sizes.
[0112] A beverage bottle 160 includes a sealing structure 100 as described in any of the above-mentioned beverage bottles;
[0113] The beverage bottle 160 also includes a bottle body 161, which is closed with a cap 110.
[0114] Please refer to Figures 1-8In this embodiment, the bottle body 161 is the main container for storing drinking liquids (such as water or cold-brewed tea), and is in the form of a conventional plastic or glass bottle. The cap 110 is detachably fitted to the bottle body 161 by means of threads, snaps, etc., to achieve bottle mouth sealing. The sealing structure 100 of the beverage bottle includes a receiving component 120, a sealing cap 170, a placement ring 130, a fixing ring 140, a pouring guide 150, etc., which are integrally fitted to the side of the cap 110 away from the bottle body 161, for sealing and storing the brewing substance, and for adding the brewing substance into the bottle body 161 to complete the brewing when needed.
[0115] The sealing structure 100 of the beverage bottle has multiple structural features such as double sealing, moisture and water resistance, and guide leakage prevention.
