Thermos cup

The present invention relates to a thermos cup, and more particularly to a locking mechanism disposed inside the lid and operating from the lid to allow the lid to maintain a circumferential cup.

A container that holds a beverage such as water for a few hours at their original temperature is a conventional item, and the beverage container is called a thermos cup. The thermos cup includes a cup body and a cup lid, and the upper end opening portion of the cup body is completely sealed by the cup lid. There are two kinds of the lids, one is a screw cap type and the other is a lid type. Among them, the cap-type thermos cup directly drinks the beverage from the opening of the cup when the cup lid is unscrewed. Such a cap-type thermos cup is not within the scope of the present discussion, so further explanation is not necessary.

The upper cover of the lid-type thermos cup is used as a fulcrum to open the upper cover of the lid, so that the upper cover can cover the drinking portion, and the upper cover can be pushed by the spring member to move in the direction of the opening, and the cup is heated. A locking mechanism is also provided to lock the upper cover in a closed state, such as the disclosed in the new domestic patents No. M452926, M455698 "Beverage Container Sealing Cap" and other known capped cups.

Since the locking mechanism of the conventional cap-type cup is conventionally provided on the peripheral wall of the cup cap, as a result, the cup cap is abruptly protruded due to the locking mechanism protruding from the peripheral wall thereof, making it difficult to maintain the circumferential integrity of the cup cap.

In addition, in order to facilitate tea making, the existing vacuum flask can also be used with a filter cup. The filter bowl rests on a flange formed radially inward from the inner wall of the cup body, And forming an interference fit with the inner wall of the cup through the elastic member protruding from the outer wall of the filter cup, so that the filter cup can be removably held in the cup body, so that the tea leaves contained in the filter cup can be immersed in hot water to produce tea. The role.

Although the filter cup can be taken out from the cup body, it is generally not done on the one hand. On the one hand, it is inconvenient. On the one hand, when the filter bowl is taken out, the tea soup will drip everywhere, so after the cup lid is unscrewed, it is directly The cup is drunk, and as a result, the tea leaves left in the filter bowl are easily drunk with the tea soup, so the tea must always be careful to avoid drinking tea at the same time.

The present invention has been made to solve the above problems, and an object thereof is to provide a heat insulating cup in which a locking mechanism can be assembled in a lid and a locking mechanism is operated from above the lid to ensure the integrity of the circumference of the lid.

The clamshell type thermos cup of the present invention comprises a cup body and a cup cover, the cup body has an opening at the upper end thereof; the cup cover comprises a lower cover body, a drinking part, an upper cover body, a sealing member and a locking mechanism The cover body is detachably assembled to the opening of the cup body; the drinking portion is disposed on the lower cover body, the bottom surface has a vent hole and an outflow hole, and the two sides are provided with a locking portion; the upper cover body is pivotally connected to the opening and closing portion a lower cover body; the sealing member is assembled to the upper cover body; the locking mechanism includes a locking member held by the compression spring to slide between the upper cover body and the sealing member, so that when the upper cover body is closed, the locking member and the drinking portion can be The locking portions are interlocked with each other, and the upper cover body is kept in a closed state under the elastic force of the compression spring, and the sealing member is sealed to close the air hole and the outflow hole; when the pressing member is pressed to move forward, the locking member can be released , the upper cover is opened.

The lower portion of the drinking portion further includes a separable gasket. The airtight contact is made with the inner wall of the opening of the cup, and the bottom surface of the gasket is provided with a plurality of filter holes.

An advantage of the present invention over conventional techniques is that the locking mechanism is assembled between the upper cover and the sealing member and the locking member is operated from above the lid so that the circumference of the lid maintains integrity because there is no locking mechanism.
