Abstract

The present invention is a filter cup having a good venting effect, comprising a cup body and a plurality of recesses recessed in the cup body, when the user places a filter paper in the cup body and brews the coffee thereby, Due to the tension of the filter paper itself, the filter paper will lie on the inner side wall of the cup after being in contact with water, and will not lie on the inner surface of each groove, and each groove penetrates the upper and lower ends of the cup body. Therefore, the smoothing of the exhaust passages can be maintained, and the existing filter cup can be effectively improved. Because the filter paper is attached to the cup body and the one of the ribs, the corresponding exhaust passage may be blocked, so that it can be obtained. A preferred venting effect provides a filter bowl with good venting.

Description

Filter cup with good exhaust effect

The present invention relates to a filter bowl, and more particularly to a filter bowl having a good exhaust effect.

When coffee is brewed, the coffee bean powder will release gas when it comes into contact with hot water. When the air bubbles are discharged upwards and ruptured, cold air will enter the space of the air bubbles, causing uneven temperature of coffee extraction and affecting coffee quality. In the process of brewing coffee, it is necessary to have a filter bowl with good exhaust function.

As shown in FIG. 6 and FIG. 7 , the conventional filter cup includes a cup body 60 and a plurality of ribs 70 . The plurality of ribs 70 are spaced apart from the inner side wall of the cup 60 when the user puts a filter paper. When the 80 is placed in the cup 60 and the coffee bean powder is poured to brew the coffee, the filter paper 80 abuts against the plurality of ribs 70, thereby forming the filter paper 80 and the cup 60 as shown in FIG. A plurality of exhaust passages 90 are formed between the side walls, and the gas discharged from the coffee bean powder can be discharged upwardly along the plurality of exhaust passages 90 to provide a good brewing effect.

However, as shown in FIG. 8, when the existing filter cup is brewed, the filter paper 80 is easily attached to the inner side wall of the cup 60 and the plurality of ribs 70 when it is in contact with water, so that the plurality of exhaust passages 90 are too narrow. Further, the filter paper 80 may also be squeezed during the brewing process and completely affixed to the cup 60 to be connected with one of the ribs 70, so that the corresponding exhaust passage 90 may be blocked and cannot be maintained smoothly. And thus affect the exhaust effect, therefore, the existing filter cup does have its need to improve.

In order to solve the problem that the existing filter cup is easily attached to the inner side wall and the rib of the cup body, thereby causing poor exhaust effect, the present invention provides a filter cup with good exhaust effect, which is provided by a plurality of grooves. Gas, effective to improve the problems encountered in the existing filter bowl, further explained below.

The present invention is a filter cup having a good venting effect, comprising a cup body and a plurality of grooves, wherein: the cup system comprises an inner side wall; and the plurality of grooves are spaced apart from the inner side wall of the cup body on.

The above filter bowl having a good venting effect, wherein the cup has an inner side wall which is tapered from the top to the bottom.

Further, the above filter bowl having a good exhaust effect, wherein each groove has the same shape.

Preferably, the filter cup having a good venting effect, wherein the width of each groove near the top end of the cup is larger than the width near the bottom end, so that the grooves have a shape of a wide width and a narrow shape.

Preferably, the filter bowl has a good exhaust effect, wherein each groove passes through the upper and lower ends of the inner side wall.

Further, the above filter bowl having a good venting effect, wherein the plurality of grooves have different lengths.

According to the above technical feature, when the user places a filter paper in the cup body and brews the coffee through the plurality of grooves recessed in the inner side wall, the filter paper will lie on the cup body when it meets water. On the inner side wall, the filter paper does not lie on the inner surface of each groove due to the tension of the filter paper itself, and since each groove penetrates the upper and lower ends of the inner side wall, the exhaust passages can be maintained. Smooth, effective improvement of the existing filter cup is easy because the filter paper is attached to the cup body and one of the ribs, and the corresponding exhaust passage may be blocked, and the problem of unsmoothness cannot be maintained.

Preferably, since the cup has an inverted cone shape, when the coffee is brewed, the amount of the coffee bean powder near the top end is more than the position near the bottom end, so the upper layer of coffee bean powder emits more gas than the lower layer of coffee beans. The gas discharged from the powder, by the wide and narrow shape of each groove, the upper layer can be discharged more than the lower layer, so that a better exhaust effect can be obtained, thereby providing a good exhaust effect. Filter bowl.

In order to be able to understand the technical features and practical functions of the present invention in detail and can be implemented in accordance with the contents of the specification, the detailed description of the preferred embodiment is further illustrated as follows:

The present invention is a filter bowl having a good exhausting effect. The first preferred embodiment is shown in FIGS. 1 and 2, and includes a cup body 10 and a plurality of grooves 20, wherein the cup body 10 is The inverted tapered shape includes an inverted inner wall 11 which is spaced apart from the inner side wall 11 of the cup 10. As shown in FIG. 2, each groove 20 penetrates the inner wall 11 The upper and lower ends of the side wall 11 and the width D of the end of each of the grooves 20 near the top end of the cup 10 are larger than the width d of the end near the bottom end, so that the grooves 20 have an upper width and a narrow shape, and each concave The grooves 20 have the same shape.

With the above technical features, please refer to FIG. 3 and FIG. 4, when the user places a filter paper 40 in the cup 10 and brews the coffee, the filter paper 40 will lie on the water when it meets the water. On the inner side wall of the cup body 10, the filter paper 40 does not lie on the inner surface of each groove 20 due to the tension of the filter paper 40 itself, and since each groove 20 penetrates the upper and lower ends of the inner side wall 11, Therefore, the smoothness of each exhaust passage 21 can be maintained, and the existing filter cup can be effectively improved. Because the filter paper 80 is attached to the cup 60 and the one of the ribs 70, the corresponding exhaust passage 90 may be blocked. Maintain a smooth flow.

Preferably, since the cup body 10 has an inverted cone shape, when the coffee is brewed, the amount of the coffee bean powder near the top end is more than the position near the bottom end, so the upper layer of coffee bean powder emits more gas than the lower layer of coffee. The gas discharged from the soybean powder has a wide and narrow shape in each groove 20, and the upper layer can be discharged more than the lower layer, so that a better exhaust effect can be obtained, thereby providing a good row. Gas filter bowl.

A second preferred embodiment of the present invention is shown in FIG. 5, which differs from the first preferred embodiment in that the cup mouth of the cup body 10A is curved so that the cup edges at different positions have different heights. The cup body 10A has an inverted tapered inner side wall 11A. The plurality of grooves 20A are spaced apart from the inner side wall 11A. Each groove 20A does not penetrate the upper end of the inner side wall 11A, and the plurality of grooves 20A They have different lengths, and when the user brews the coffee by the cup 10A, the plurality of grooves 20A can be exhausted upward.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any one of ordinary skill in the art may use the present invention without departing from the scope of the present invention. Equivalent embodiments of the various changes or modifications made by the disclosed technical content, and without departing from the technical solutions of the present invention, are still within the scope of the technical solutions of the present invention.
