Description

[Detailed explanation of the invention] Recently, coffee packs called regular coffee, which are vacuum-packed coffee grounds containing ground coffee powder for each use, have become popular, but they require a filter to drink. do.

Therefore, there are products on the market that package the coffee pack and the filter as a set so that the filter can be easily obtained.

However, even with such products, there is the inconvenience that if hot water is not available, you will not be able to drink it immediately even if you want to.

In view of the above points, the present invention provides a portable set that includes coffee, tea, and other beverages that require filtration, a filter, and a thermos bottle for storing hot water, and has the advantage of being ready to drink when you want to drink it. This is an attempt to provide a thermos bottle with a filter.

The embodiments of the present invention will be described below based on the drawings.
2 is the main body of the thermos bottle, 2 is a stopper attached to the main body 1 of the thermos, and 3 is a cup lid that covers the stopper 2 with a space 4 formed therebetween. This is provided with a protrusion 6 on the upper outer periphery of the thermos bottle main body 1 which is threadedly engaged with a protrusion 5 provided in a spiral shape, and is attached integrally with the thermos bottle main body 1 by threading these protrusions 5 and 6 together. .

A portion of the side wall of this cup lid 3 from the bottom 9 to a position slightly below the spiral protrusion 6 is formed into an oval side wall 8.
A locking part 7 consisting of a step part 10 projecting along an elliptical contour line from a position slightly below the spiral protrusion 6 on the inner wall of the cup lid 3 is provided.

Reference numeral 11 denotes a filter, which has a shape that can be built into the space 4 between the stopper lid 2 and the cup lid 3, and is made of plastic with a circular bottom 12 and a slightly tapered circular side wall 1.
an outer vessel body 14 integrally molded with the outer vessel body 1 and the outer vessel body 1;
A container body that fits into the outer container body 14 has an elongated bottom portion 15 and a side wall 17 that is tapered on its four sides and opens so as to fit into the opening edge 16 of the outer container body 14, which are integrally molded from plastic. It consists of an inner vessel body 18, and both vessel bodies 1
There is a filtrate outlet 1 in the center of the bottom 12.15 of 4.1B.
9 is provided at the bottom of the filter 11, and a locking edge 20 having the same outline as the oval outline of the stepped part 10 is screwed into a threaded groove part 21 carved on the outer periphery of the entrance of the thermos bottle body 1. A locking cylinder 22 is provided for locking by doing so.

In addition·. The stepped portions 10 may be provided at various locations along the oval contour.

Next, to explain how to use the above-mentioned thermos bottle with a filter, which is made from outside the premises, when the filter 11 is stored in the cup lid 3, the long axis of the locking edge 20 is connected to the step provided on the cup lid 3. If the filter 11 is inserted into the cup lid 3 so as to match the long axis of the elliptical contour line 10, the entire locking edge 20 will be directed toward the bottom 9 of the cup lid 3 without being caught by the stepped portion 10. You can put it in.

When using the filter 11, place the cup lid 3 with its opening edge facing upward, as shown in Figure 7, so that the long axis of the locking edge 20 coincides with the short axis of the circular outline of the stepped portion 10. In other words, if the filter 11 is inserted into the cup lid 3 with the orientation changed by 90 degrees from the stored orientation, the portion of the locking edge 20 on the long axis side will abut against the upper end surface of the stepped portion 10 and will be locked. , filter 11 and cup lid 3
Lock it so that it is installed on the upper end side.

Therefore, by attaching a filter paper to the inner wall of the inner container body 18 of the filter 11, putting coffee powder etc. into the white of the filter paper, and pouring the hot water stored in the thermos bottle body 1 into the coffee powder etc., The filtrate is transferred to the filtrate outlet 19.
It is used by allowing more water to flow out and collecting it in the cup lid 3 for drinking.

In addition, when storing boiled coffee in the thermos bottle body 1, as shown in FIG.
are screwed together and locked so that the filter 11 is installed in the center of the thermos bottle main body 1.

Thereafter, it is used in the same manner as described above.

In this latter usage mode, various means other than screwing the bottom of the filter 11 into the thermos bottle body 1 may be employed, such as fitting the bottom part by applying pressure.

Since the present invention is constructed as described above, the equipment for drinking not only regular coffee but also black tea and other beverages that require filtration can be integrated into a thermos bottle, which can be carried anywhere and can be drunk immediately when desired. We can provide convenient thermos bottles with filters.

Moreover, it is not necessary to support the filter by hand, the filtering operation becomes easy, and it has the advantage that it can be locked to both the cup lid and the thermos bottle.
