Those skilled in the relevant technical field can reasonably determine the specific meanings of the above terms in the present utility model in combination with the specific content of the technical solution.

[0029] In order to adapt to the fast-paced life, some existing instant beverages, such as coffee or tea, etc., can use an extractor to brew beverage capsules to quickly obtain the beverage. Existing beverage capsules generally include a shell and a filter membrane. The filter membrane divides the internal space of the shell to form a mixing chamber and a liquid outlet chamber. The mixing chamber stores solid raw materials. The extractor can pierce the shell of the beverage capsule with an injection needle and extend it into the mixing chamber to inject hot water. The hot water extracts or dissolves the solid raw materials, and then the liquid passes through the filter membrane and enters the liquid outlet chamber. During this period, the extractor can pierce the shell of the beverage capsule with a liquid extraction needle and extend it into the liquid outlet chamber to discharge the beverage liquid.

[0030] In the prior art, in order to simplify the structure of the extractor, a needle plate is arranged in the liquid outlet chamber of some beverage capsules. The needle plate is moved or deformed by pressure to pierce the shell, so as to discharge the beverage liquid. Due to the need to set the needle plate, the structure of the beverage capsule is relatively complex and the production cost is relatively high.

[0031] Refer to Figures 1 to 3 , the beverage capsule of the embodiment of the present invention includes a housing 100 and a filter membrane 200. The housing 100 is provided with an accommodation chamber; the filter membrane 200 is arranged in the housing 100 and divides the accommodation chamber to form a mixing chamber 110 and a liquid outlet chamber 120. The mixing chamber 110 is used to store solid raw materials; wherein the housing 100 is provided with a thin wall portion 130 that is used to break under pressure at the shell wall corresponding to the liquid outlet chamber 120.

[0032] When the beverage capsule is in use, the extractor can pierce the shell with an injection needle and extend it into the mixing chamber 110, and then continuously inject hot water into the mixing chamber 110. The extracted or dissolved liquid can enter the liquid outlet chamber 120 through the filter membrane 200, so that the pressure in the liquid outlet chamber 120 gradually increases. When the pressure in the liquid outlet chamber 120 reaches a certain level, the thin wall portion 130 will break and the liquid in the liquid outlet chamber 120 can flow out. Thus, there is no need to set a needle plate, which simplifies the structure of the beverage capsule, makes the structure of the beverage capsule relatively simple, and the production cost is relatively low.

[0033] In the embodiment, the minimum wall thickness of the thin wall portion 130 is A, and 0.03 mm ≤ A ≤ 0.15 mm is satisfied. The above minimum wall thickness of the thin wall portion 130 can meet the requirement for the thin wall portion 130 to break when the pressure in the liquid outlet chamber 120 is normal after hot water is injected, and it is not easy for the thin wall portion 130 to break accidentally when the beverage capsule is not in use, and the use effect is good.

[0034] Specifically, in this embodiment, the minimum wall thickness A of the thin-walled portion 130 is 0.05 mm, and the use effect is good. It can be understood that the specific size of the minimum wall thickness of the thin-walled portion 130 can be appropriately adjusted according to parameters such as the shell material, the brewing pressure of the solid raw material, and the injection pressure of hot water. Those skilled in the art can specifically configure it according to actual needs. It can be understood that the minimum wall thickness of the thin-walled portion 130 can take any value between 0.03 mm and 0.15 mm.

[0035] In the embodiment, the thin-walled portion 130 is convexly arranged relative to the housing 100, so that the thin-walled portion 130 is more likely to rupture when the internal pressure in the liquid outlet chamber 120 reaches a certain level, and the use effect is more stable; and the liquid in the liquid outlet chamber 120 can flow out more smoothly.

[0036] In the embodiment, the thin-walled portion 130 is conical, and the wall thickness of the thin-walled portion 130 is the smallest at its tip, so that when the pressure in the liquid outlet chamber 120 reaches a predetermined value, the thin-walled portion 130 can rupture relatively stably, reducing the use risk caused by the housing not being able to rupture at the thin-walled portion 130, and the use effect is good.

[0037] It can be imagined that the thin-walled portion 130 can also be an outwardly convex hemispherical structure, and it can also have a similar function.

[0038] It can be imagined that the thin-walled portion 130 can also be other shapes. For example, the thin-walled portion 130 is a small piece body, that is, the thin-walled portion 130 is a small piece body structure with a relatively thin wall thickness on the housing, etc. Those skilled in the art can specifically configure it according to actual needs.

[0039] In the embodiment, the housing 100 is convexly provided with a guiding rib 140, and the thin-walled portion 130 is located beside the guiding rib 140. After the pressure in the liquid outlet chamber 120 causes the thin-walled portion 130 to rupture, the beverage liquid in the liquid outlet chamber 120 flows out through the gap formed by the rupture of the thin-walled portion 130. At this time, the possible flow path of the liquid may be relatively chaotic, which is not convenient for collecting the beverage liquid. By providing the guiding rib 140, the liquid flowing out from the liquid outlet chamber 120 can be uniformly guided by the guiding rib 140, which is convenient for the extractor to collect the flowing-out liquid.

[0040] Specifically, the guiding rib 140 is outwardly convex and conical, which is convenient for gradually converging the beverage liquid flowing out from the liquid outlet chamber 120, and the guiding effect is good. It can be understood that the shape of the guiding rib 140 can also be other shapes, such as an outwardly convex hemispherical shape, etc. Those skilled in the art can specifically configure it according to actual needs.

[0041] In the embodiment, six thin-walled portions 130 are provided and arranged in a dotted pattern, and all the thin-walled portions 130 are evenly distributed around the guide ribs 140. The above structure facilitates the liquid in the liquid outlet chamber 120 to flow out relatively quickly and evenly from the cracks of the thin-walled portions 130, and the liquid beverage flowing out from the cracks of each thin-walled portion 130 is easily guided by the guide ribs 140; at the same time, the thin-walled portions 130 are arranged in a dotted pattern so that the structural strength of other positions of the housing is basically not affected.

[0042] Specifically, two, three or more thin-walled parts 130 may be provided on the housing, and those skilled in the art may make a selection according to actual needs.

[0043] In an embodiment, a clearance groove 150 is formed on the outer side of the housing 100 , and the thin-walled portion 130 is entirely located in the clearance groove 150 , so that the thin-walled portion 130 is not easily contacted by foreign objects and caused to be accidentally damaged.

[0044] In the embodiment, a diverter plate 300 is further included. The diverter plate 300 is disposed in the housing 100 and divides the mixing chamber 110 into a water injection chamber 111 and a solid chamber 112. The water injection chamber 111 and the liquid outlet chamber 120 are disposed on opposite sides of the solid chamber 112. The diverter plate 300 is provided with a plurality of diverter channels, and the water injection chamber 111 is connected to the solid chamber 112 through the diverter channels. The extractor first injects hot water into the water injection chamber 111 through the injection needle, and then the hot water can flow into various places of the solid chamber 112 relatively evenly through the plurality of diverter channels of the diverter plate 300, so that the overall extraction effect of the hot water on the solid raw material is better.

[0045] In the embodiment, the diverter plate 300 is provided with a plurality of flow holes, the flow holes form a diverter channel, and the diameter of the flow hole is B1, which satisfies 0.3mm≤B1≤1.2mm. The above-mentioned flow holes allow the injected hot water to flow evenly into various parts of the solid chamber 112 at a relatively appropriate speed, and the use effect is better. It is understandable that the diameter of the flow hole can be any value between 0.3 mm and 1.2 mm, such as 0.4 mm, 0.8 mm, etc., and those skilled in the art can make specific selections according to product specifications.

[0046] In the embodiment, the diverter plate 300 is provided with a plurality of flow gaps, the flow gaps form a diverter channel, and the width of the flow gap is B2, satisfying 0.3mm≤B2≤1.2mm. The above-mentioned flow gaps allow the injected hot water to flow evenly into all parts of the solid chamber 112 at a relatively appropriate speed, and the use effect is better. It is understandable that the width of the flow gap can be any value between 0.3 mm and 1.2 mm, such as 0.4 mm, 0.8 mm, etc., and those skilled in the art can make specific selections according to product specifications.

[0047] Specifically, the outer shell of the beverage capsule is made of a relatively soft plastic material, and the flow diverter 300 is also made of a relatively soft plastic material. The flow diverter 300 can be connected and fixed to the outer shell by means of ultrasonic welding or hot melting. The area of the outer shell outside the thin-walled portion 130 should be able to withstand an internal pressure of 15 atmospheres.

[0048] Specifically, the filter membrane 200 can be made of materials such as non-woven fabric or filter paper.

[0049] Specifically, the outer shell of the beverage capsule includes a cup body and a sealing film. The cup body and the sealing film enclose a containing cavity. The outer periphery of the sealing film is fixedly connected to the peripheral edge of the cup mouth of the cup body. The thin-walled portion 130 is located at the bottom of the cup body.

[0050] In the description of this specification, the descriptions with reference to the terms "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
