Description

Technical Field

[0001] The utility model relates to the field of food, in particular to a beverage capsule and an extraction component. Background Art

[0002] Traditional beverage brewing methods are time-consuming and laborious. Some existing beverage brewing methods, such as coffee or tea, can pre-place solid raw materials into beverage capsules, and use commercially available capsule extraction machines for automatic brewing to quickly obtain beverages. Some existing beverage capsules include a shell and a seepage disc, the shell has a receiving cavity, the seepage disc is connected to the shell and divides the receiving cavity into a mixing chamber and a liquid outlet chamber, and the seepage disc is provided with a seepage hole, the mixing chamber is connected to the liquid outlet chamber through the seepage hole, and the mixing chamber is filled with solid raw materials. When using the capsule extraction machine and this beverage capsule to brew a beverage, the capsule extraction machine first pierces the injection needle through the shell and inserts it into the mixing chamber, and pierces the liquid extraction needle through the shell and inserts it into the liquid outlet chamber. Then the injection needle injects hot water into the mixing chamber, and the solid raw materials are extracted or dissolved in the mixing chamber. During this period, the liquid in the mixing chamber slowly enters the liquid outlet chamber through the seepage hole, which increases the pressure inside the mixing chamber. Therefore, the solid raw materials in the mixing chamber can be relatively fully extracted or dissolved, and the liquid extraction needle discharges the liquid in the liquid outlet chamber. However, in the early stage of injecting hot water into this beverage capsule, hot water can also flow into the mixing chamber through the seepage hole, so some of the hot water fails to fully extract or dissolve the solid raw materials, and the flavor and quality of the beverage still have room for improvement.

If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figures 1 to 3 , is a beverage capsule of an embodiment of the utility model, comprising a housing 100, a seepage disc 200 and a pressure relief membrane 300. The housing 100 is provided with a containing chamber; the seepage disc 200 is arranged in the housing 100 and divides the containing chamber into a mixing chamber 110 and a liquid outlet chamber 120, the seepage disc 200 is provided with a seepage hole 210, and the mixing chamber 110 can communicate with the liquid outlet chamber 120 through the seepage hole 210; the pressure relief membrane 300 is arranged in the housing 100 and separates the mixing chamber 110 from the liquid outlet chamber 120, and when the pressure of the mixing chamber 110 increases to a predetermined pressure, the pressure relief membrane 300 can rupture and make the mixing chamber 110 communicate with the liquid outlet chamber 120 through the seepage hole 210.

[0032] During the process of the injection needle injecting hot water into the mixing chamber 110, the internal pressure of the mixing chamber 110 continues to increase, and the pressure relief membrane 300 prevents the hot water from flowing into the liquid outlet chamber 120; when the internal pressure of the mixing chamber 110 increases to a predetermined pressure, the hot water injected previously has fully extracted or dissolved the solid raw materials, at which time the pressure relief membrane 300 ruptures and allows the liquid in the mixing chamber 110 to slowly flow into the liquid outlet chamber 120 and eventually be discharged, and the seepage disc 200 allows the mixing chamber 110 to maintain a relatively high internal pressure during the subsequent extraction process and maintain sufficient extraction or dissolution, so that the hot water injected into the beverage capsule can more fully extract or dissolve the solid raw materials, thereby improving the flavor and quality of the beverage.

[0033] In the embodiment, the pressure relief membrane 300 is connected to the side of the seepage pan 200 close to the mixing chamber 110. Since the pressure relief membrane 300 may generate fragments after being ruptured, the pressure relief membrane 300 is connected to the side of the seepage pan 200 close to the mixing chamber 110, and the ruptured fragments of the pressure relief membrane 300 are difficult to enter the liquid outlet chamber 120 through the seepage hole 210, thereby reducing the safety problem caused by the fragments of the pressure relief membrane 300 mixing into the beverage, and maintaining the quality and safety of the beverage.

[0034] It is conceivable that in other embodiments, the pressure relief membrane 300 may also be connected to a side of the seepage disc 200 close to the liquid outlet chamber 120 , and those skilled in the art may configure the pressure relief membrane 300 according to actual needs.

[0035] In the embodiment, the seepage plate 200 is provided with a plurality of seepage holes 210, and the pressure relief membrane 300 covers all the seepage holes 210 near the opening of the mixing chamber 110. The plurality of seepage holes 210 can speed up the speed at which the liquid in the mixing chamber 110 flows into the liquid outlet chamber 120, so that the extraction and dissolution speeds meet the use requirements, and can reduce the risk of some seepage holes 210 being blocked and affecting the flow of liquid into the liquid outlet chamber 120, and a pressure relief membrane 300 covers all the seepage holes 210, which can simplify the manufacturing difficulty of the beverage capsule.

[0036] It is conceivable that a plurality of pressure relief membranes 300 may be provided, and each pressure relief membrane 300 covers the openings of several seepage holes 210; or the pressure relief membranes 300 are provided to correspond to the number of seepage holes 210, and the pressure relief membranes 300 cover the openings of the seepage holes 210 one by one. Those skilled in the art may make specific configurations according to actual needs.

[0037] In the embodiment, the pressure relief film 300 is an aluminum tin film, which can be broken when a predetermined pressure is reached, has a simple structure, low material cost, and good food safety. It is understandable that the thickness of the pressure relief film 300 can be different according to different types of solid raw materials, so that the pressure relief film 300 can be broken when a suitable pressure is reached. It is conceivable that the pressure relief film 300 can also be a film of other materials, and those skilled in the art can specifically configure it according to actual needs, such as a plastic film or a metal film of other materials.

[0038] In the embodiment, the seepage disc 200 is provided with eighteen rows of seepage holes 210 around its central axis, and each row of seepage holes 210 includes four seepage holes 210 arranged radially along the central axis of the seepage disc 200. The above structure enables the liquid in the mixing chamber 110 to flow into the liquid outlet chamber 120 more evenly through the seepage disc 200. It is conceivable that the seepage disc 200 can also be provided with two, three or more rows of seepage holes 210 around its central axis, and each row of seepage holes 210 includes two, three or more radially arranged seepage holes 210, and those skilled in the art can make specific configurations according to actual needs.

[0039] It is conceivable that the seepage tray 200 may also be provided with two or more seepage holes 210, and the seepage holes 210 may be arranged and distributed, or may be irregularly distributed, and those skilled in the art may configure the specific configuration according to actual needs.

[0040] In the embodiment, a filter membrane 400 is further included. The filter membrane 400 is disposed in the mixing chamber 110 and divides the mixing chamber 110 into a solid chamber 111 and a liquid chamber 112. The filter membrane 400 is disposed at intervals from the seepage disc 200, and the liquid chamber 112 is disposed between the seepage disc 200 and the filter membrane 400. The filter membrane 400 is disposed so that the solid raw material cannot pass through the filter membrane 400 and contact the seepage disc 200, thereby avoiding the risk of small solid particles entering the liquid outlet chamber 120 through the seepage holes 210, and allowing the extracted or dissolved liquid to flow more smoothly from the liquid chamber 112 through the seepage holes 210 into the liquid outlet chamber 120, and retaining the residue of the solid raw material in the solid chamber 111. Specifically, the material of the filter membrane 400 can be, for example, non-woven fabric, filter paper, or nylon yarn, and those skilled in the art can configure it specifically according to actual needs.

[0041] It is understandable that, in some embodiments, the beverage capsule may not be provided with the filter membrane 400, and those skilled in the art may configure the filter membrane 400 according to actual needs.

[0042] In the embodiment, the housing 100 includes a cup body 130 and a cover film 140. The cup body 130 is provided with a receiving groove, the seepage disc 200 is installed in the receiving groove, the cover film 140 is connected to the cup body 130 and covers the notch of the receiving groove, and the cover film 140 and the cup body 130 are enclosed to form a receiving cavity. The above-mentioned beverage capsule can be produced separately during production, and the pressure relief membrane 300 can be installed on the seepage disc 200, and then the seepage disc 200 is installed in the cup body 130, and then the filter membrane 400 is installed in the cup body 130. After the solid raw material is filled, the cover film 140 can be used to seal the cup body 130 to make a beverage capsule, and the structure can be processed well.

[0043] It is conceivable that in other embodiments, the cup body 130 and the seepage disc 200 may also be integrally formed.

[0044] In the embodiment, the seepage tray 200 includes a plate body 220 and a support column 230. The seepage hole 210 is provided in the plate body 220. The outer periphery of the plate body 220 abuts against the side wall of the receiving groove. The support column 230 is connected to a side of the plate body 220 close to the liquid outlet chamber 120. One end of the support column 230 abuts against the bottom wall of the receiving groove. The above structure makes it difficult for the seepage tray 200 to shake in the housing 100. The support column 230 can support the seepage tray 200, so that when the pressure of the mixing chamber 110 is greater than that of the liquid outlet chamber 120, the seepage tray 200 can also maintain the stability of the position, so that the structural strength of the beverage capsule is better.

[0045] In the embodiment, the bottom wall of the receiving groove is provided with a positioning boss 131, and one end of the pillar portion 230 is provided with a positioning matching hole, which abuts against the positioning boss 131. The positioning boss 131 and the positioning matching hole are provided so that the installation position of the pillar portion 230 of the seepage tray 200 can be relatively accurately fixed, reducing the risk of the pillar portion 230 being offset in the installation position.

[0046] In the embodiment, the shell wall of the housing 100 is provided with at least two structural layers, and an anti-oxidation layer is provided between the structural layers, which can improve the sealing performance and structural strength of the housing 100 and provide better protection for solid raw materials. Specifically, the structural layer is made of polycarbonate, the number of structural layers can be set to two layers, three layers or more, and the anti-oxidation layer can also be set to one layer, two layers or more, and those skilled in the art can make specific configurations according to actual needs.

[0047] The utility model also discloses an extraction assembly for the beverage capsule, comprising the beverage capsule, a first extraction seat and a second extraction seat. The first extraction seat is provided with an injection needle, one end of which can pierce the beverage capsule and extend into the mixing chamber 110; the second extraction seat is provided with a liquid extraction needle, one end of which can pierce the beverage capsule and extend into the liquid outlet chamber 120. When the first extraction seat and the second extraction seat are closed, the injection needle and the liquid extraction needle can be directly inserted into the beverage capsule respectively, so as to better adapt to the use structure of the beverage capsule.

[0048] Specifically, the beverage capsule of the utility model is extracted by inserting an external injection needle and a liquid extraction needle into the capsule cup. The injection needle pierces the beverage capsule and extends into the solid chamber 111, and then hot water is injected. After the hot water extracts or dissolves the solid raw materials, it passes through the liquid chamber 112 and the seepage disc 200 and enters the liquid outlet chamber 120. The liquid extraction needle pierces the liquid outlet chamber 120 and extends into the liquid outlet chamber 120, so that the liquid flows out of the beverage capsule. The injection needle can blow air to blow the remaining liquid in the beverage capsule into the liquid outlet chamber 120 to reduce the liquid residue in the beverage capsule.

[0049] Specifically, the beverage capsule of the present invention can contain solid raw materials of coffee, tea or other types of beverages. Those skilled in the art can configure the capsule according to actual needs, which is not limited here.
