Description

Technical Field

[0001] The utility model relates to the technical field of brewing supplies, in particular to a brewing aluminum foil capsule. Background Art

[0002] With the optimization of the office environment, coffee brewing machines used with brewing capsules have begun to be widely used in homes, offices and other scenarios.

[0003] The shell of the existing brewing capsule is usually made of high temperature resistant plastic material, such as PET, PP material, etc. By storing different brewing materials (such as tea, coffee, etc.) in the storage cavity inside the shell, beverages with different flavors can be obtained during brewing.

[0004] However, plastic material is a polymer, which is composed of a long-chain molecular structure composed of repeating units, which contains many gaps and voids. These microstructures allow gas molecules to diffuse and penetrate through the structural gaps of the polymer material to a certain extent. Therefore, the brewing capsule with a plastic shell has a certain oxygen permeability, which causes the brewing material in the brewing capsule to volatilize most of the original flavor of the brewing material after a short storage period, thereby affecting the aroma and taste of the brewed beverage, and the shelf life is also relatively short.

[0005] Therefore, further improvements are needed. Utility Model Content

[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0031] First embodiment

[0032] See also Figure 1-Figure 4 The brewing aluminum foil capsule comprises a capsule body 1, the inner side of the capsule body 1 is provided with a storage cavity 11 for storing brewing materials, the upper and lower sides of the capsule body 1 are respectively provided with a water inlet 12 and a water outlet 13, the capsule body 1 is integrally formed by an aluminum foil material, the water inlet 12 is sealed and connected with an upper sealing film 2, and the upper sealing film 2 is processed and formed by an aluminum foil material. Since the capsule body 1 and the upper sealing film 2 are both made of aluminum foil, and aluminum foil is a metal material, its crystal structure makes the aluminum foil have a very tight lattice structure, the atomic arrangement of aluminum and the properties of the metal bond make the aluminum foil itself have a very good isolation effect on oxygen and other gases, and will not be oxygen-permeable, and a very thin oxide layer will be formed on the surface of the aluminum, and this oxide layer will further prevent oxygen from penetrating, reducing the overall oxygen permeability of the capsule, thereby extending the shelf life of the brewing material in the storage cavity 11.

[0033] In addition, the capsule body 1 made of aluminum foil is soft and easy to recycle, thus reducing the pollution to the environment.

[0034] Preferably, the height of the capsule body 1 is d1, 49 mm<d1<50 mm, and the overall height of the brewing aluminum foil capsule is relatively high.

[0035] Furthermore, a water dividing plate 3 is provided on the upper side of the storage chamber 11, and a lower water chamber 14 is formed between the water inlet 12 and the water dividing plate 3. The periphery of the water dividing plate 3 is tightly connected to the inner wall of the capsule body 1, and a plurality of lower water holes 31 are distributed on the water dividing plate 3. The lower water chamber 14 is connected to the storage chamber 11 through the lower water holes 31. When the aluminum foil capsule is brewed, high-pressure hot water first enters the lower water chamber 14 from the water inlet 12. Under the action of the lower water holes 31 of the water dividing plate 3, the hot water can enter the storage chamber 11 more evenly, thereby avoiding uneven brewing of the brewing material. At the same time, directly flushing high-pressure water into the storage chamber 11 will cause part of the powdered brewing material to float upward. The water dividing plate 3 can avoid the brewing material from floating upward to the brewing machine.

[0036] Furthermore, a first bending portion 151 is provided on the side wall of the capsule body 1 at a position corresponding to the water dividing sheet 3, and the water dividing sheet 3 is connected and cooperated with the inner side of the first bending portion 151. The first bending portion 151 can improve the structural strength of the capsule body 1. At the same time, the first bending portion 151 can also improve the connection strength between the capsule body 1 and the water dividing sheet 3, so that the water dividing sheet 3 is not easy to fall off.

[0037] Furthermore, a filter screen 4 is provided at the bottom of the material storage cavity 11 , and a vertical distance is formed between the filter screen 4 and the water outlet 13 . The filter screen 4 can prevent the residue of the brewing material from entering the water outlet 13 , thereby improving the drinking taste of the user.

[0038] Furthermore, an aluminum foil sheet 5 is connected to the side of the filter screen 4 facing the storage chamber 11, and the aluminum foil sheet 5 is tightly connected to the inner side of the capsule body 1. The aluminum foil sheet 5 can further improve the sealing performance of the storage chamber 11. When high-temperature water enters the storage chamber 11 and starts to brew, the pressure on the aluminum foil sheet 5 will gradually increase, and eventually the aluminum foil sheet 5 will rupture or separate from the inner side of the capsule body 1 under the action of pressure, so that the liquid can flow smoothly to the filter screen 4.

[0039] Furthermore, a filter bracket 6 is connected to the side of the filter 4 facing the water outlet 13, and the filter bracket 6 abuts against the inner side of the capsule body 1. The filter bracket 6 can improve the rigidity of the filter 4 to prevent the filter 4 from deforming and affecting its filtering effect.

[0040] Furthermore, a reinforcing rib is provided on the side of the filter bracket 6 facing the water outlet 13, and the reinforcing rib includes a plurality of annular ribs 61 arranged along the circumferential direction and a plurality of strip ribs 62 arranged along the radial direction. The strip ribs 62 and the annular ribs 61 are staggered to further improve the structural strength of the filter bracket 6.

[0041] Furthermore, the capsule body 1 is provided with a second bending portion 152 corresponding to the filter bracket 6, and the second bending portion 152 is in a step shape. The bottom position of the filter bracket 6 is tightly connected to the second bending portion 152, so that the filter bracket 6 is easier to connect and cooperate with the capsule body 1, and the capsule body 1 has a better supporting effect on the filter bracket 6.

[0042] Furthermore, a third bending portion 153 is provided at a lower position of the capsule body 1 corresponding to the second bending portion 152. The third bending portion 153 forms a continuous wave shape through continuous bending. When the capsule body 1 is subjected to greater pressure near the bottom during transportation, the third bending portion 153 can achieve a buffering effect by slightly deforming itself, thereby reducing the chance of damage to the capsule body 1.

[0043] Preferably, a fourth bending portion 154 is provided at the lower side of the capsule body 1 corresponding to the third bending portion 153. The fourth bending portion 154 is in a convex shape corresponding to the outer side of the capsule body 1. The fourth bending portion 154 can be connected and cooperated with the corresponding groove on the brewing machine to achieve the effect of quickly positioning and guiding the installation of the aluminum foil capsule and the brewing machine.

[0044] Preferably, each wave shape of the third bending portion 153 is in an arc shape.

[0045] Furthermore, an upper connecting plane 17 is provided on the capsule body 1 at a peripheral position corresponding to the water inlet 12, and the upper sealing membrane 2 is sealedly connected to the upper connecting plane 17, thereby increasing the connection area between the capsule body 1 and the upper sealing membrane 2, thereby improving the sealing performance of the connection position between the two.

[0046] The upper connecting plane 17 is extended outward in the horizontal direction, and a reinforcing ring 18 is provided on the outer side of the upper connecting plane 17 to improve the structural strength of the capsule body 1 .

[0048] See also Figure 5 , Figure 6 The difference between this embodiment and the first embodiment is that the height of the brewing aluminum foil capsule is d2, 34mm<d2<36mm, and the overall height of the capsule body 1 is relatively short.

[0049] The remaining undescribed parts are the same as those of the first embodiment and will not be repeated here.

[0050] Third embodiment

[0051] See also Figure 7 The difference between this embodiment and the first embodiment is that the bottom of each wave-shaped portion of the third bending portion 153 of the brewing aluminum foil capsule is at least partially flat.

[0052] The remaining undescribed parts are the same as those of the first embodiment and will not be repeated here.

The tearing ear 71 extends radially outward. The lower sealing film 7 can further improve the preservation effect of the brewing aluminum foil capsule. When in use, the lower sealing film 7 can automatically separate from the capsule body 1 under the action of water pressure, or the lower sealing film 7 can be torn off from the capsule body 1 by the tearing ear 71 before use.
