Description

Technical Field

[0001] This invention relates to the field of packaging container technology, and particularly to a convenient container with a built-in sealed cavity that facilitates mixing of contents with the main substance during use. It is particularly suitable for, but not limited to, beverage preparation, food preparation, pharmaceutical formulation, chemical reagent mixing, cosmetic essences, pre-cooked meals, outdoor food, and daily chemical products. The container can be designed in various forms such as cups, bowls, jars, bottles, and boxes, including but not limited to tall cups, short cups, wide-mouthed bowls, and narrow-mouthed bottles, depending on the application scenario. Background Technology

[0002] In existing technologies, the beverage, food, and pharmaceutical industries often require the mixing of two or more separate materials before use. For example, disposable brewing cups use a filter at the bottom to encapsulate tea leaves, but this results in insufficient extraction and inconvenient cleaning. Some medicine bottles require additional tools to mix powders and solvents, which is cumbersome and poses a risk of contamination. Concentrated daily chemical or chemical products require precise measurement and mixing with a base liquid, a complex process. These existing mixing methods generally suffer from complex packaging, insufficient mixing, multiple steps, reliance on additional tools, and the tendency for components to loosen during distribution. Therefore, there is an urgent need for a new container solution that can achieve convenient, thorough, and integrated mixing. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a container with a built-in accommodating cavity and a multi-functional opening component, which can achieve convenient and thorough mixing of the contents and the main substance, and has the advantages of simple operation, reliable fixation and wide applicability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A container with a built-in accommodating cavity includes a container body (1) with an accommodating cavity (2) inside. The opening of the accommodating cavity (2) is sealed by a water-resistant sheet (3), and the water-resistant sheet (3) is connected to a tear-off component (4) via an easily detachable connecting part (5). The tear-off component (4) adopts two optimized implementation methods: In implementation method A, it is a foldable clamping stirring rod structure, which has the functions of opening, stirring and stable placement, and the end of the stirring rod can be set as a spoon-shaped structure, which also has the function of scooping; In implementation method B, it is an extended lifting tongue structure, the end of which can be fixed by being connected to the outer wall of the container through the easily detachable connecting part (5), or simply by relying on the plasticity of the material itself to adhere to the outer wall of the container.

[0005] As an optimization, the easily separable connecting part (5) is one of the following: weak adhesive layer, easy-tear line structure, point break structure, micro-perforated structure, snap-on structure or magnetic adsorption structure.

[0006] As an optimization, the container can be a beverage cup, a food can, a medicine bottle, a reagent bottle, or a daily chemical product packaging bottle. Beneficial effects

[0007] Compared with the prior art, the present invention has the following significant technical advancements and beneficial effects: 1. Fundamentally Expanded Application Scope: By broadening the protected object from a "cup" to a "container," this technical solution becomes universally applicable to multiple technical fields, including beverage preparation, food processing, pharmaceutical formulation, chemical reagent mixing, and the use of daily chemical products. It solves the common technical problem of temporarily mixing contents with the main substance in different fields. The container can flexibly adapt to different shapes, such as tall cups for beverages, wide-mouthed bowls for food, reagent bottles for medicine, and narrow-mouthed bottles for cosmetics, all while achieving the same internal containment cavity and multi-functional opening capabilities.

[0008] 2. Significantly improved functional integration and ease of use: By designing a foldable and clampable stirring rod structure, the three major functions of opening the container, mixing the contents, and stably placing the stirring tool are integrated into a single component, optimizing and simplifying the user's operation process. The integrated extended tongue structure achieves reliable fixation of the tongue before circulation and use through the easily separable connecting part (5), or achieves a fit through the plasticity of the material itself, significantly improving the convenience and reliability of the opening operation.

[0009] 3. Enhanced versatility and feasibility of the technical solution: By adopting the overarching concept of “easily separable connection part” (5), it covers a variety of specific technical means to achieve separation, such as weak bonding, mechanical weakening, and physical connection. This provides clear guidance for those skilled in the art to select the most suitable implementation method according to different container types, contents characteristics and production processes, thereby enhancing the feasibility of the technical solution in different application scenarios.

[0010] 4. Solved long-standing technical pain points: The two core structures provided by this invention effectively overcome the technical defects of the prior art, such as insufficient mixing, cumbersome operation steps, reliance on additional tools, and easy loosening of the opening parts during circulation, which can lead to sealing failure or contamination. It provides a better comprehensive technical solution.

[0011] 5. Optimized warehousing and transportation efficiency: Both embodiments of the present invention fully consider the stacking and storage requirements of containers. In Embodiment A, the foldable stirring rod (6) is tightly attached to the container opening (11) in the folded clamping state, without increasing the stacking height of the containers; in Embodiment B, the overhanging section (71) of the extended lifting tongue is fixed to the outer wall of the container through the easily separable connecting part (5) or relies on the plasticity of the material itself to fit, without any protruding structure. Both designs enable multiple containers to be stacked tightly, significantly improving the space utilization rate of warehousing and transportation and reducing logistics costs.

[0012] 6. Achieving precise measurement and on-demand preparation: In pharmaceutical, cosmetic, and chemical applications, the container (2) is pre-filled with single-dose / useful contents (such as powder, essence powder, and chemical additives). Users can use it directly after tearing off the sealing film without having to repackage or mix it themselves, thus avoiding dosage errors and ensuring product stability and safety. Especially in the pharmaceutical field, this design eliminates the risk of drug contamination during dispensing; in the cosmetic field, it ensures the freshness and effectiveness of active ingredients; and in the industrial field, it reduces direct contact between operators and chemicals.

[0013] 7. Enhanced Food Convenience and Freshness: In applications such as pre-cooked meals, outdoor food, and convenience foods, this invention enables airtight food preservation and on-the-go preparation, eliminating the need for users to carry extra utensils or tear open multiple individual packages, thus improving the convenience of outdoor dining and emergency meals. Simultaneously, dehydrated foods, due to long-term airtight preservation, effectively prevent moisture absorption and spoilage, extending their shelf life. Attached Figure Description

Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] Example 1: As Figure 1 and Figure 2 The following is an embodiment A of the present invention. This embodiment takes cup-packaged tea as an example. The container body (1) is a paper cup with a receiving cavity (2) at the bottom for storing tea leaves. The water-resistant sheet (3) is an aluminum-plastic composite film, which is heat-sealed. The tear-off part (4) is a tongue (7) integrally stamped from the water-resistant sheet (3). The free end of the tongue (7) extends about 2 cm beyond the container opening (11) and bends downward to form a hanging section (71). The end of the hanging section (71) is detachably fixed to the outer wall of the container body (1) through an easily separable connecting part (5) (in this embodiment, a coated weak adhesive layer).

[0021] When in use, the user pinches the hanging section (71) with their fingers and gently pulls it diagonally upwards. The easily separable connecting part (5) (i.e., the weak adhesive) is then peeled off, and the entire water-resistant sheet (3) can be smoothly removed to make tea in a cup.

[0022] Example 2: As Figure 3 The following is an embodiment B of the present invention. This embodiment takes a disposable beverage cup as an example. The container body (1) is a paper cup, and its bottom is formed by hot pressing to form a receiving cavity (2), which is pre-filled with coffee powder. The opening of the receiving cavity (2) is heat-sealed by a water-resistant sheet (3) made of aluminum-plastic composite film. A stirring rod (6) made of rigid PP plastic is connected to the tongue end of the water-resistant sheet (3) through an easily separable connecting part (5) (in this example, a weak adhesive structure).

[0023] The stirring rod (6) includes a stirring body (61), a folded extension (62) connected by a thin-walled plastic connector (as a folding mechanism 63), and a V-shaped clamping part (64) at the end. In use, the user pinches the clamping part (64) and pulls it upwards, breaking the heat-sealed structure and removing the water-resistant sheet (3). Then, the folded extension (62) is unfolded to be in a straight line with the stirring body (61), resulting in an extended stirring rod for stirring. When not in use, the folded extension (62) is bent and secured to the container opening (11) using the elasticity of the clamping part (64) for stable placement.

[0024] Example 3 (Preferred Heat-Sealing Structure): As a further optimization of the present invention, the water-resistant sheet (3) is fixed to the opening of the accommodating cavity (2) by a heat-sealing process. Specifically, the edge of the water-resistant sheet (3) forms an annular heat-sealing area with a width of 1-3 mm, which is tightly adhered to the inner wall of the container body (1) by heat pressing. This width range ensures sufficient sealing strength to prevent the contents from getting damp or leaking, while also ensuring a smooth feel when the user tears it open, avoiding difficulty in tearing open due to an excessively wide heat seal. Those skilled in the art can select a suitable heat-sealing width within this preferred range based on the container material, the characteristics of the contents, and the manufacturing process.

[0025] Example 4 (Non-fixed extended tongue structure): As another embodiment of the present invention, the tongue (7) is integrally formed with the water-resistant sheet (3), and its free end extends beyond the opening (11) of the container body (1) and bends downward to form a hanging section (71). The hanging section (71) adheres to the outer wall of the container body (1) solely by the plasticity of the material itself, without the need for additional fixing connections. In use, the user can directly pinch the hanging section (71) and pull it upward to remove the water-resistant sheet (3) as a whole. This structure simplifies the production process, reduces costs, and is especially suitable for materials with good plasticity such as aluminum foil.

[0026] Example 5 (Multifunctional Tableware-Style Stirring Rod): As another embodiment of the present invention, the end of the rigid stirring rod (6) is configured as a spoon-shaped structure, which enables it to perform both stirring and scooping functions. This example uses an infant formula can as an example. The container body (1) is a wide-mouth can, and the containing cavity (2) is filled with formula. After the user tears open the water-resistant sheet (3), the stirring rod (6) can be unfolded, which can be used to stir the formula or scoop the formula. This design is particularly suitable for food, pharmaceuticals, daily chemical products and other fields that require precise measurement and mixing. As a further optimization, the thickness of the spoon-shaped structure is controlled at 1-3 mm, so that it does not significantly increase the overall height of the containers when stacked in the folded and clamped state, which is convenient for stacking multiple containers and saves storage and transportation space. Those skilled in the art can select a suitable thickness within this preferred range according to the container material and stacking requirements.

[0027] Example 6 (Medicine - Precision Measurement Version): This example uses a medicine brewing bottle as an example. The main body of the container (1) is a cup body, and its bottom is provided with a receiving cavity (2), which contains a single dose of medicine powder. The opening of the receiving cavity (2) is heat-sealed by a water-resistant sheet (3). The tear-off part (4) is a tongue (7) integrally formed with the water-resistant sheet (3). The free end of the tongue (7) extends beyond the container opening (11) and bends downward to form a hanging section (71). The end of the hanging section (71) is fixed to the outer wall of the cup body through an easily separable connecting part (5). When in use, the user pinches the hanging section (71) and pulls it upward to remove the water-resistant sheet (3), and the medicine powder is exposed in the cup for use. Pour warm water into the cup, and the medicine powder mixes and dissolves with the warm water, which can be drunk directly. This structure enables precise metering of the powder, eliminating the need for users to dispense the medication themselves and avoiding dosage errors. It also ensures that the powder is sealed and moisture-proof before use, guaranteeing the stability and effectiveness of the medicine.

[0028] Example 7 (Cosmetic Products - Stirring Stick Type): This example uses an essence bottle as an example. The main body (1) of the container is a glass or plastic bottle with a receiving cavity (2) at the bottom. The receiving cavity (2) contains a single-use amount of concentrated essence powder or active ingredients. The opening of the receiving cavity (2) is heat-sealed by a water-resistant sheet (3). The tear-off part (4) is a rigid stirring stick (6). The end of the stirring stick (6) inside the bottle is set as a spoon-shaped structure. The folded extension (62) outside the bottle mouth is connected to the tongue-hanging section (71) of the water-resistant sheet (3) through an easily separable connecting part (5). The stirring stick (6) includes a stirring main body (61) and a folded extension (62) connected by a folding mechanism (63). The end of the folded extension (62) is provided with a clamping part (64). When in use, the user pinches the clamp (64) and pulls it upward to remove the water-resistant sheet (3), exposing the essence powder inside the bottle for easy use. Alternatively, the base liquid can be injected into the bottle. The stirring rod (6) can be unfolded for direct mixing, or the spoon-shaped end can be used to scoop the essence or assist in application. When not in use, the folded extension (62) can be bent and secured to the bottle opening (11) using the clamp (64) for easy placement. This structure enables precise dosage of the essence ingredients and allows for on-demand preparation, eliminating the need for users to dispense or mix the ingredients themselves. Furthermore, the stirring rod also functions as a scooping tool, enhancing ease of use.

[0029] Example 8 (Industrial Use - Chemical Additives): This example uses a chemical additive bottle as an example. The container body (1) is an HDPE plastic bottle with a accommodating cavity (2) at the bottom. The accommodating cavity (2) is pre-filled with a single-use amount of chemical additive powder or granules (such as catalysts, stabilizers, scale inhibitors, etc.). The opening of the accommodating cavity (2) is heat-sealed by a water-resistant sheet (3) made of aluminum-plastic composite film. The tear-off part (4) is a rigid stirring rod (6). The end of the stirring rod (6) is set as a spoon-shaped structure. The folded extension (62) outside the bottle mouth is connected to the tongue-hanging section (71) of the water-resistant sheet (3) through an easily separable connecting part (5). The stirring rod (6) includes a stirring body (61) and a folded extension (62) connected by a folding mechanism (63). The end of the folded extension (62) is provided with a clamping part (64). In use, the user pinches the clamp (64) and pulls it upward to remove the water-resistant sheet (3), exposing the additive powder inside the bottle for easy use. Alternatively, the user can inject solvent or base liquid into the bottle, unfold the stirring rod (6) to stir, and obtain the prepared chemical solution. This structure enables precise metering and on-demand preparation of additives, avoiding the additives from becoming damp and ineffective due to long-term exposure. It also reduces direct contact between operators and chemicals, improving operational safety.

[0030] Example 9 (Food - Pre-prepared dishes / outdoor food): This example uses a convenient food container as an example. The main body of the container (1) is a disposable paper cup, paper bowl or plastic container, with one or more accommodating cavities (2) at the bottom. The accommodating cavity (2) is pre-filled with dehydrated food for single use, including but not limited to dehydrated vegetables, freeze-dried meat, instant rice, instant soup mix, instant porridge powder, instant noodle crumbs, instant oatmeal, etc. The opening of the accommodating cavity (2) is heat-sealed by a high-temperature resistant water-resistant sheet (3) (such as OPP film or aluminum-plastic composite film). The tear-off part (4) is a rigid stirring rod (6), the end of which is set as a spoon-shaped structure, which has both stirring and scooping functions. The folded extension part (62) of the stirring rod outside the container opening is connected to the tongue-hanging section (71) of the water-resistant sheet (3) through an easily separable connecting part (5). The stirring rod (6) includes a stirring body (61) and a folding extension (62) connected by a folding mechanism (63). The end of the folding extension (62) is provided with a clamping part (64). When in use, the user pinches the clamping part (64) and pulls it upward to remove the water-resistant sheet (3). The dehydrated food is then exposed at the bottom of the container and ready to use. Water is poured into the container to brew the food, and the stirring rod (6) is unfolded to stir, thus obtaining edible soups, porridges, rice, or compound dishes. When not in use, the folding extension (62) can be bent and secured to the edge (11) of the container using the clamping part (64) for easy placement. This structure is particularly suitable for various scenarios such as pre-cooked meals, outdoor food, military rations, emergency food, instant noodles, instant soup, and self-heating food. It achieves sealed preservation of food and allows for immediate consumption. Users do not need to carry extra utensils or tear open multiple individual packages, improving the convenience of outdoor dining and emergency food. Meanwhile, the dehydrated food pre-placed in the container (2) is effectively prevented from getting damp and deteriorating due to long-term sealed storage, thus extending the shelf life of the food.

[0031] The "separable connection part" (5) described in this invention refers to a part that can separate under normal tearing force applied by the user, thereby allowing the tearing part (4) to detach from the water-resistant sheet (3), or allowing the lifting tongue (7) to separate from the outer wall of the container. Its implementation is not limited to those listed in this embodiment; any equivalent transformations made using the concept of this invention should be included within the scope of protection of this invention.
