DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermos having a filtering function for coffee, tea and the like.

[0002]

2. Description of the Related Art In order to easily drip coffee outdoors and drink, a thermos bottle in which a thermos bottle body for adding hot water, a filter, and a lid / cup is combined has been conventionally known (Japanese Utility Model Publication No. 59-59). 40903).

[0003] In the above-mentioned conventional thermos bottle, a lid serving as a lid is put on the shoulder of the main body and screwed together, and a filter is accommodated in a space between the cup and the main body.

[0004]

In the above-mentioned thermos bottle, there is a case where the dripped coffee is stored in the thermos bottle main body and taken out outdoors, or used as a normal thermos bottle without drip purpose. In these cases, since a filter is unnecessary, it is common to remove the filter and reduce the weight to carry. However, in the conventional structure, even if the filter is removed, the form in which the cup is screwed into the main body does not change, so the height of the product does not change,
Therefore, compactness could not be achieved.

[0005] On the other hand, when used outdoors in a campsite or the like, a large amount of drip liquid may be stored in a thermos bottle using a filter. However, the filter described above is a space between a cup and a main body. Since it is housed in a part, its capacity cannot be made very large. For this reason,
When trying to drip coffee or the like using the filter, there is an inconvenience that a large amount of hot water cannot be poured.

Accordingly, it is an object of the present invention to solve these problems and to reduce the size of the filter when the filter is unnecessary and to increase the capacity of the filter.

[0007]

In order to achieve the above object, the present invention relates to a thermos bottle comprising a thermos bottle body, a cup-type filter and a lid / cup, and the inside of an inner peripheral surface of an opening of the filter is provided. An outer engaging portion is provided on an outer peripheral surface of the joint portion, and a filter engaging portion is provided at an opening of the main body of the thermo bottle to engage with the inner engaging portion. The thermo bottle is provided on an inner peripheral surface of the lid / cup. A filter engagement portion of the main body and an engagement portion that engages with an outer engagement portion of the filter were provided, and the filter was mounted on the opening of the thermos bottle main body and the cup was mounted on the filter. A configuration and a configuration in which the cup is attached to the opening of the thermos main body can be selected.

The inner engaging portion of the filter and the engaging portion of the cup are formed by female threads, respectively, and the outer engaging portion of the filter and the filter engaging portion of the thermos main body are formed by male threads. Select between a form in which the filter is put on the opening of the thermos bottle body and screwed together, and a cup is put on the filter and screwed in, and a form in which the cup is put on the opening of the thermos main body and screwed. You can do it.

[0009]

In the above construction, when the filter is unnecessary, the cup is directly attached to the thermos main body. To drip with a filter, place the filter opening upward and place it on the opening of the main body, drip as usual, pour into the cup after drip and drink.

[0010] The above-mentioned filter is turned upside down to cover the opening of the main body and engage with the filter engaging portion of the shoulder. Having a depth of up to For this reason, a capacity | capacitance becomes large structurally.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a thermos bottle according to an embodiment includes a main body 1, a cup-shaped filter 2, and a lid / cup cup 3. The main body 1 has a shoulder 5 attached to a vacuum double container 4 made of stainless steel, and a stopper 7 is inserted into the container 4 through an opening 6 of the shoulder 5.
Is to be inserted.

The filter 2 is fitted downwardly from above the stopper 7 by screwing a female screw 8 provided on the inner peripheral surface of the opening thereof into a male screw 9 of the shoulder 5. A handle 11 is integrally provided on the outer peripheral surface of the filter 2. On the outer peripheral surface of the filter 2, a male screw 12 is provided at a lower part (an upper part in the state of FIG. 1) of the handle 11.

Further, a step 13 is provided below the male screw 12 and has a smaller diameter by one step. The step 13 rests on the opening 6 of the shoulder 5 (see FIG. 4). A drip hole 14 on the bottom surface (the upper end surface in the state of FIG. 1) of the filter 2
The mesh 15 is stretched (see FIG. 2).

The cup 3 covers about half of the bottom surface of the filter 2, and a female screw 16 provided on the inner peripheral surface of the opening is screwed to the male screw 12 of the filter 2. As shown in FIG. 3, the female screw 16 is provided with the male screw 9 of the shoulder 5 described above.
Also screwed. In other words, the male screw 9 of the shoulder 5
The external thread 12 of the filter 2 has the same shape. The handle 11 is provided on the outer peripheral surface of the filter 2 exposed from below the cup 3, and the handle 18 is provided on the outer peripheral surface of the cup 3.

The thermos bottle of the embodiment is as described above, and the minimum depth of the filter 2 is the depth from the upper surface of the stopper 7 to the threaded portion of the screws 8 and 9. That is, the bottom surface is in contact with the plug 7 even if it is the shallowest, and if necessary, the bottom portion is deepened as shown to further increase the capacity.

Next, how to use the above-mentioned magic bottle will be described. When the drip coffee is taken out at home, as shown in FIG. 4, the filter 2 is inverted and the step 13 is placed on the opening 6 of the shoulder body 5, and the filter 17 is attached. Then filter 1
7. Put coffee beans into 7 and pour hot water to drip inside the main body 1.

Thereafter, a stopper 7 is provided, and a cup 3
, And the cup 3 is screwed onto the shoulder body 5 and carried (see FIG. 3).

When drip outdoors, a plug 7
And carry it with the filter 2 and the cup 3 attached in two stages as shown in FIG. When drip,
Attach the filter 17 and put coffee beans into it.
Receiving the cup 3 below, pour hot water and make it drip.

When used as a normal thermos bottle, the filter 2 is removed as shown in FIG.

In the above-described embodiment, the means for mutually engaging the thermos main body 1, the filter 2 and the cup 3 uses screwing means by screws. However, the present invention is not limited to this. Appropriate engaging means can be used.

[0021]

As described above, according to the present invention, when the filter is unnecessary, the filter is removed and the cup is directly engaged with the main body, so that the height of the product can be reduced, and the product can be reduced in size and weight. .

Further, since the filter has a depth reaching at least the filter engaging portion of the shoulder from the upper surface of the stopper of the main body,
The capacity can be increased, and as a result, the amount of hot water poured during drip is convenient.

When the filter and the cup are stacked in two stages and mounted on the thermos main body, there is a portion exposed to the outside on the outer peripheral surface of the filter, and a handle can be provided on the exposed portion. This handle facilitates handling of the filter.
