Abstract
Description
Technical Field
[0001] This invention relates to the technical field of brewing products, specifically to a brewing aluminum foil capsule. Background Technology
[0002] With the improvement of office environment, brewing machines that are used with capsules are also beginning to be widely equipped in homes, offices and other scenarios.
[0003] There are generally two types of spouts for brewing capsules: normally open and sealed. Brewing capsules with normally open spouts have a shorter shelf life. When high-pressure hot water enters the brewing capsule, it can be easily discharged from the spout. The spout can also be sealed to extend the shelf life of the brewing capsule. However, since the sealing film needs to be broken by the pressure of high-pressure hot water, it is easy for too much hot water in the brewing capsule to overflow into the spout, affecting the normal use of the brewing capsule. Alternatively, the user may need to puncture the sealing film by hand before use, which is both inconvenient and unhygienic.
[0004] Therefore, further improvements are needed. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a brewing aluminum foil capsule that can prevent hot water from overflowing from the inlet, is simple to operate, and is more hygienic to use.
[0006] A refillable aluminum foil capsule includes a capsule body with a storage cavity for storing refillable material on the inner side of the capsule body. The upper and lower sides of the capsule body are respectively provided with a water inlet and a water outlet. The water outlet is sealed with a lower sealing membrane. A support is provided between the storage cavity and the water outlet. The support has a protruding post on the side facing the water outlet, which can press against the lower sealing membrane to separate the lower sealing membrane from the water outlet. The protruding post extends in the direction of the water outlet.
[0007] As a specific embodiment, the capsule body has a protrusion protruding downwards at the position corresponding to the water outlet, and a lower connecting plane is provided on the side of the protrusion facing the storage cavity, and the lower sealing membrane is sealed and connected to the lower connecting plane.
[0008] As a specific embodiment, a bending buffer section is provided between the protrusion and the side wall of the capsule body, and the bending buffer section is in the shape of a continuously bent wave.
[0009] As a specific embodiment, the outer side of the convex column is provided with a number of convex teeth, which are evenly distributed along the circumference of the convex column.
[0010] As a specific embodiment, the side of the protruding tooth facing the water outlet is provided with a guide slope, which is inclined outward from bottom to top.
[0011] As a specific embodiment, the support is provided with a reinforcing rib on the side facing the water outlet. The reinforcing rib includes several radially arranged strip ribs, which intersect at the center of the bottom of the support.
[0012] As a specific embodiment, the protruding column is located at the bottom center of the bracket, and the strip ribs intersect with the protruding column.
[0013] As a specific embodiment, a filter screen is connected to the side of the support facing the storage cavity, and a sealing aluminum foil is connected to the side of the filter screen facing the storage cavity. The sealing aluminum foil is sealed to the inside of the capsule body.
[0014] As a specific solution, the water inlet is sealed with an upper sealing membrane, which is formed by processing aluminum foil.
[0015] A water divider is provided on the upper side of the storage chamber, and a lower water chamber is formed between the water inlet and the water divider. The periphery of the water divider is tightly connected to the inner wall of the capsule body.

[0026] Figure 8 This is an exploded view of the third embodiment of the present invention. Detailed Implementation
[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0028] First embodiment:
[0029] See Figures 1-5 This instant aluminum foil capsule includes a capsule body 1. The inner side of the capsule body 1 has a storage cavity 11 for storing the instant ingredients. The upper and lower sides of the capsule body 1 are respectively provided with a water inlet 12 and a water outlet 13. The water outlet 13 is sealed with a lower sealing film 2. The lower sealing film 2 can improve the sealing of the storage cavity 11, thereby improving the overall preservation effect of the aluminum foil capsule.
[0030] A support 3 is provided between the storage chamber 11 and the outlet 13. The support 3 has a protruding post 31 on the side facing the outlet 13, which can press against the lower sealing membrane 2 to separate the lower sealing membrane 2 from the outlet 13. The protruding post 31 extends towards the outlet 13. When the aluminum foil capsule is placed in the preset position of the brewing machine, the switch of the brewing machine can apply pressure to the aluminum foil capsule to slightly deform the capsule body 1, so that the outlet 13 moves towards the protruding post 31. When the protruding post 31 presses against the lower sealing membrane 2, the lower sealing membrane 2 will be punctured by the protruding post 31 or separated from the outlet 13, so that the liquid can flow out smoothly from the outlet 13.
[0031] By providing the protruding post 31, users can easily puncture the lower sealing membrane 2, thereby preventing hot water from overflowing from the inlet 12, reducing the difficulty of using the aluminum foil capsule, and making the application of the aluminum foil capsule more hygienic.
[0032] Preferably, the height of the capsule body 1 is d1, where 49mm < d1 < 50mm, and the overall height of the brewing capsule is relatively high. Furthermore, the capsule body 1 has a protrusion 14 protruding downwards at the position corresponding to the water outlet 13. The protrusion 14 has a lower connecting plane 141 on the side facing the storage cavity 11. The lower sealing membrane 2 is sealed to the lower connecting plane 141, which increases the connection area between the capsule body 1 and the lower sealing membrane 2, thereby improving the sealing performance of the connection position between the two. At the same time, compared with setting the lower sealing membrane 2 on the side of the water outlet 13 facing away from the storage cavity 11, the lower sealing membrane 2 is less likely to fall off accidentally.
[0033] Furthermore, a bending buffer portion 15 is provided between the protrusion 14 and the side wall of the capsule body 1. The bending buffer portion 15 is in the shape of a continuous bend in a wave shape. When the capsule body 1 is subjected to greater pressure at the bottom during transportation, the bending buffer portion 15 can achieve a buffering effect through slight deformation, reducing the chance of damage to the capsule body 1. At the same time, when the protrusion 14 is compressed, the bending buffer portion 15 can deform to make it easier for the outlet 13 to be pressed onto the protruding post 31, and the lower sealing film 2 can be more easily punctured or separated from the capsule body 1.
[0034] Preferably, each wave shape of the third bend 15 is an arc shape.
[0035] Furthermore, a number of protruding teeth 311 are distributed on the outer side of the protruding column portion 31. The protruding teeth 311 are evenly distributed along the circumference of the protruding column portion 31. When the protruding teeth 311 act on the lower sealing membrane 2, it is easier to puncture the lower sealing membrane 2.
[0036] Furthermore, a guide slope 312 is provided on the side of the protruding tooth 311 facing the outlet 13. The guide slope 312 is inclined outward from bottom to top, making the lower side of the protruding part 31 more pointed, and the lower sealing membrane 2 can be punctured more easily.
[0037] Furthermore, the support 3 is provided with a reinforcing rib on the side facing the outlet 13. The reinforcing rib includes several radially arranged strip ribs 32, which intersect at the bottom center of the support 3 to improve the structural strength of the support 3.
[0038] Furthermore, the protruding column 31 is located at the bottom center of the bracket 3, and the strip ribs 32 intersect with the protruding column 31 respectively, so that the protruding column 31 is not easily deformed by pressure.
[0039] Furthermore, a filter screen 4 is connected to the side of the support 3 facing the storage chamber 11. The filter screen 4 can filter and prevent the residue of the brewing material from flowing out of the outlet 13.
[0040] A sealing aluminum foil 5 is connected to the side of the filter screen 4 facing the storage chamber 11. The sealing aluminum foil 5 is sealed to the inside of the capsule body 1. The sealing aluminum foil 5 can further improve the sealing performance of the storage chamber 11. When high-temperature water enters the storage chamber 11 and begins to brew, the pressure on the sealing aluminum foil 5 will gradually increase. Eventually, it will break under the pressure or separate from the inside of the capsule body 1, allowing the liquid to flow smoothly to the filter screen 4.
[0041] Furthermore, the inlet 12 is sealed with an upper sealing membrane 6, which is formed by processing aluminum foil.
[0042] A water divider 7 is provided on the upper side of the storage chamber 11. A lower water chamber 16 is formed between the water inlet 12 and the water divider 7. The periphery of the water divider 7 is tightly connected to the inner wall of the capsule body 1. Several drain holes 71 are distributed on the water divider 7. The lower water chamber 16 is connected to the storage chamber 11 through the drain holes 71. When brewing aluminum foil capsules, high-pressure hot water first enters the lower water chamber 16 from the water inlet 12. Under the action of the drain holes 71 of the water divider 7, the hot water can enter the storage chamber 11 more evenly, avoiding uneven brewing of the brewing material. At the same time, directly pouring high-pressure water into the storage chamber 11 will cause some powdered brewing material to float upward. The water divider 7 can prevent the brewing material from floating upward into the brewing machine.
[0043] Furthermore, the lower sealing film 2 is formed by processing aluminum foil, and the capsule body 1 is integrally formed by forming aluminum foil. Since aluminum foil is a metal material, its crystal structure results in a very dense crystal lattice structure. The atomic arrangement and metallic bond properties of aluminum make the aluminum foil itself very effective in isolating gases such as oxygen, preventing oxygen from passing through. Moreover, a very thin oxide layer will form on the aluminum surface, which will further prevent oxygen from penetrating, reducing the overall oxygen permeability of the brewing capsule, thereby extending the freshness time of the brewing material in the storage chamber 11.
[0044] In addition, the aluminum foil capsule body 1 is relatively soft and easy to recycle, reducing environmental pollution. The capsule body 1 is not easily damaged when subjected to pressure from the switch of the brewing machine, allowing the protruding part 31 to act more smoothly on the lower sealing membrane 2 without affecting the normal flow of liquid from the outlet 13.
[0045] Second embodiment:
[0046] See Figure 6 , Figure 7 The difference between this embodiment and the first embodiment is that the height of the novel brewing capsule is d2, 34mm < d2 < 36mm, and the overall height of the capsule body 11 is relatively short.
[0047] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.
[0048] Third embodiment:
[0049] See Figure 8 The difference between this embodiment and the first embodiment is that the bottom of each wave shape of the third bend 15 of the instant aluminum foil capsule is at least partially planar.
[0050] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.
[0051] The above embodiments are merely preferred embodiments of the present invention, and the present invention may have other implementations. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope set forth in the claims of this application.
