Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

In the present invention, unless specified to the contrary, use of the terms of orientation such as "upper, lower, top, bottom" or the like are generally described with respect to the orientation shown in the drawings or the positional relationship of the components with respect to each other in the vertical, or gravitational direction.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1 and 2, the present invention provides a novel beverage capsule, which comprises a capsule body 1 formed with a capsule inner cavity, wherein the top end of the capsule inner cavity is closed and the bottom end is provided with a water outlet nozzle 5. Wherein, this beverage capsule includes especially the filter layer 4 set up in the capsule inner chamber, the surface interval of this filter layer 4 distributes and has a plurality of filtration pores 41, filter layer 4 separates the capsule inner chamber into the pressure boost filter chamber Q1 of top and the beverage outflow chamber Q2 of below, and beverage filler 3 is filled in pressure boost filter chamber Q1.

Wherein, the filtering holes 41 can be designed to be small-bore diameter, so that the filtering layer 4 can play a role of filtration and pressurization, and the water and the beverage filling in the capsule can be fully dissolved and extracted in the pressurizing filtering cavity Q1. The beverage filling in the pressurizing filter cavity Q1 can be more fully utilized, and the obtained beverage is more mellow.

Wherein the filter layer 4 is preferably in the form of a sheet-shaped filter sheet, and the aperture of the filter holes 41 in the filter sheet is preferably 0.3mm to 0.5mm, which is much smaller than the aperture of the filter holes in a common beverage capsule. The distribution density of the filter holes 41 is designed, so that the corresponding pressurizing and extracting requirements can be met. Of course, the filter layer 4 may be in other forms, such as a woven filter screen with 100-150 meshes, which is not illustrated here.

Referring to fig. 1, the filter layer 4 separates the pressurizing filter chamber Q1 and the beverage outflow chamber Q2, so that the outer periphery of the filter layer 4 is sealingly connected to the inner peripheral wall of the inner cavity of the capsule. Specifically, the middle portion of the filter layer 4 is raised upward with respect to the outer peripheral edge portion. Thus, under the pressurizing effect of the pressurizing filter chamber Q1, the middle part of the filter layer 4 is pressed to deform downwards and does not press the space of the beverage outflow chamber Q2 too much, so that the beverage flowing out of the beverage outflow chamber Q2 is smooth and not sudden and slow. More preferably, the filter layer 4 should be an elastic material layer capable of having an elastic restoring force and being reusable.

When the filter layer 4 is preferably a filter sheet, different pore sizes and distribution densities are designed according to different types of drinks, and the size specification of the filter sheet is also suitable for the capsule bodies 1 with different sizes, so that the filter layer 4 is manufactured and assembled independently. In the embodiment shown in fig. 1, the inner peripheral wall of the capsule cavity is formed in particular with a radially inwardly projecting annular abutment 12, the outer periphery of the filter layer 4 being supported on the abutment face of the annular abutment 12. In fig. 1, an annular downward flange is formed on the outer periphery of the filter layer 4, the downward flange abuts against the support surface, and under the action of upper pressure, the outer periphery (i.e. the downward flange) of the filter layer 4 can tightly adhere to the support surface to form a reliable annular seal.

In order to seal the capsule body 1, a sealing film 2 is arranged at the top end of the inner cavity of the capsule, and a pressurizing filter cavity Q1 is formed between the sealing film 2 and the filter layer 4. A piercing needle connected to the liquid supply system can penetrate the sealing membrane 2, which is eccentrically arranged and from which the high-pressure liquid is sprayed onto the inner wall of the capsule interior, forming a swirling flow in the capsule interior, which facilitates full contact with the beverage filling.

Correspondingly, the capsule body 1 can be formed into a cup shape with an upward opening, a peripheral flange 11 which is radially outward is formed at the cup opening part at the top end of the capsule body 1, the diameter of the sealing film 2 is larger than that of the cup opening of the inner cavity of the capsule, and the periphery of the sealing film 2 can be tightly attached to the top surface of the peripheral flange 11 through colloid and the like. Thus, the sealing film 2 can completely seal the opening of the cup body.

The capsule body 1 is assembled with an independent filter plate and then sealed by a sealing film 2. The size of the formed beverage capsule is small, for example, in the example of fig. 1, the diameter A of the cup mouth of the inner cavity of the capsule is preferably 35mm to 50mm, the height C of the pressurizing filter cavity Q1 is 30mm to 40mm, and the height difference D between the sealing membrane 2 and the bottom surface of the water outlet nozzle 5 is 40mm to 50 mm. The radial width B of the peripheral flange 11 of the capsule body 1 is 1 mm-3 mm.

The capsule body 1 is preferably formed in one piece, the spout 5 being formed integrally in the centre of the bottom of the capsule body 1, the bottom of the spout 5 being provided through with a plurality of outlet holes 51 communicating with the beverage outflow chamber Q2. The extracted beverage is collected in the beverage outflow chamber Q2 and finally flows out from the water outlet nozzle 5. For this purpose, the beverage outflow chamber Q2 is formed as a reduced diameter chamber, the diameter ratio of the filter layer 4 at the top end of the beverage outflow chamber Q2 to the spout 5 at the bottom end preferably being not less than 4, the reduced diameter chamber facilitating the collection of the beverage.

Further, faucet 5 is covered with bottom indent blind hole 52, and faucet 5 is still including setting up the kuppe 6 in bottom indent blind hole 52, and this kuppe 6 includes the center outlet port 62 of bottom and the many water conservancy diversion muscle 61 that disperse and arrange along circumference interval from the periphery of center outlet port 62, preferably 4 ~ 6, and the liquid that flows out from outlet port 51 is collected to center outlet port 62 through water conservancy diversion muscle 61 and is flowed out. The flow guiding ribs 61 play a role in guiding flow, so that the flow speed and the temperature of the beverage are continuous. The flow guiding ribs 61 are formed in the inner concave blind holes 52 to prevent external pollution. In the example of FIG. 1, the inner diameter F of the bottom recessed blind hole 52 is 5mm to 9mm, and the axial height E of the water outlet nozzle 5 is 4mm to 10 mm. In addition, the bottom of the water outlet nozzle 5 can be covered with a removable film which is removed when in use, so as to prevent external pollution from entering the inner cavity of the capsule.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention, for example, the filter layer 4 is not limited to a single layer, but also can be a plurality of layers stacked at intervals, the outer contour of the capsule body 1 can be a circular oval shape for convenience of illustration, etc., and other shapes, such modifications, etc. are included in the protection scope of the present invention.

It should be noted that the various technical features described in the above embodiments can be combined in any suitable manner without contradiction, and the invention is not described in any way for the possible combinations in order to avoid unnecessary repetition.

In addition, any combination of the various embodiments of the present invention is also possible, and the same should be considered as the disclosure of the present invention as long as it does not depart from the spirit of the present invention.
