2. Description of the Related Art As a hot water bottle with a cover, Japanese Utility Model Publication 5
Nos. 2-26229 and 57-16579, Shokai 53
Prior art examples such as 148593 can be cited, all of which are made of plastic. For this reason, after the hot water is injected, the internal pressure becomes lower as the cooling is performed, which causes deformation. When the capacity is full, there is no problem. On the other hand, when the internal capacity is small at the fifth minute or the like, the upper surface serving as the air chamber is greatly deformed, and in some cases, it cannot be restored. It should have been manufactured with due consideration given to the uniformity and stability of deformation, but in reality, the above-mentioned problem has occurred.

The inventor of the present invention has previously devised a hot water bottle that can be erected and obtained registration (Japanese Utility Model 4-2042).
No. 0). Because the hot water bottle can be set up, there is no need to take up space for display at the store, it is convenient to handle in small places, and there is the effect that it is not necessary to support by hand when discharging hot water The implemented products have been well received. However, the application of this configuration to a hot water bottle with a cover has not yet been put to practical use.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and its object is to reinforce the structure of the main body, prevent thermal deformation, and reduce the amount of hot water to be deformed and restored. Regardless, it is to ensure that it is performed normally and reliably.

Another object of the present invention is to provide a hot water bottle with a cover that has a function of stably standing.

[0006]

In order to solve the above-mentioned problems, the present invention provides an uneven portion on a main body for reducing deformation of the main body due to heating and cooling, and a cover contacts the main body at an outer portion, In the inner part, a measure is taken in which a gap is kept between the cover and the main body, and the inner part is pressed and stopped by the cap.

Further, an abutment for stabilizing the flat main body in an upright state is integrally provided on an outer portion of the main body by plastic molding means, and the main body is erected to balance the load on the cover side. Means is provided to give the abutment part a tilt component for tilting to the lower surface side.

BEST MODE FOR CARRYING OUT THE INVENTION
It has a plastic body and a cover, and is similar to the above-mentioned conventional one in that the cover is fixed to the body by a plastic cap. However, in the case of the present invention, an uneven portion is provided to cope with deformation of the main body.

The uneven portion minimizes deformation of the main body due to heating and cooling, and reduces distortion of the upper and lower surfaces of the main body as a whole. It is desirable that the uneven portion has a uniform shape and structure in terms of shape and structural strength. The lower surface of the main body has a structure that can be deformed while increasing strength.

Further, the present invention is also characterized by a structure in which the cover is fixed to the main body, thereby improving the deformation resistance of the main body. That is, the cover has an arch-shaped cross-sectional shape, thereby contributing to structural reinforcement of the main body.
In order to fix the cover, only the inner part of the cover is pressed by the cap, a gap is maintained between the inner part of the cover and the main body, and the outer part is in contact with and fixed to the main body.

Although the cover is pressed by the cap at the inner part around the pouring port, the cover does not pressurize the main body due to the gap, and the pressing force by the cap is treated so as to press the main body at the outer part. Is done. For this reason, when the cap is applied to the pouring port, the cover does not press the cover against the central portion of the main body. On the other hand, if the lower side of the cover comes in contact with the main body when the cap is applied to the pouring port, there is a possibility that a sufficient force for tightening the cap may not be obtained.

In the case of the present invention, the force for tightening the cap acts directly on the cover and only on the outer part of the cover on the body. Therefore, the strength on the upper surface side of the main body is significantly increased. Further, the deformability of the main body excluding the outer portion and the stability of the deformed portion are further improved.

The primary role of the cover is to protect the user from obstructions caused by direct skin contact with the body over the top of the body, for example, low-temperature burns. In the present invention, the above role is expected from the cover as in the related art, and the present invention is characterized in that the structure is strengthened by the cover.

Further, an abutment for stabilizing the flat main body in an upright state is integrally provided on an outer portion of the main body by plastic molding means, and the main body which is erected to balance the load on the cover side is provided. It is assumed that a tilt component for tilting to the lower surface side is given to the abutment portion. Further, it is desirable that the abutment portion be grounded at, for example, three or four points, and that a portion between them be depressed to be manufactured by means such as blow molding to obtain a stable standing state. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. The illustrated hot water bottle 10 with a cover includes a hot water bottle main body 11 and a cover 21. The main body 11 has a circular flat shape and has a vertically flat shape, and a pouring port 12 is provided at the center of the upper surface so as to protrude upward, and a cap 15 is provided around the pouring port 12. One of the coupling means 13 for mounting is formed.

The main body 11 is provided with a radial groove as an uneven portion 14 for strengthening the structure of the upper surface portion and preventing deformation. See FIG. Also, the structure is strengthened on the lower surface portion, and a corrugated structure is provided as the uneven portion 16 for absorbing the deformation acting thereon. Such a shape and structure are formed when the main body 11 is molded by a blow molding method.

On the other hand, a receiving portion 17 is provided substantially all around the outer edge of the main body 11 so that the outer portion 22 of the cover 21 can be supported. Similarly, an abutment portion 18 for stabilization is provided at a position below the main body 11 when the main body 11 is erected, and the abutment portion 18 has four front, rear, left and right corners as support points 18a, 18a, 18a, 18a. In addition, a concave portion 18b is provided between them, so that an accurate abutment shape can be obtained even by a blow molding method. See FIGS. For the abutment part 18, the main body 11
In order to cope with the center of gravity of the main body 11 leaning toward the cover when the center of gravity is raised as described later, an inclination component A for tilting the main body 11 backward (that is, toward the lower surface side) is provided. See FIG.
Further, a hand 19 is provided at a position which is turned up when standing. The carrier 19 has a non-hollow structure so that heat is not applied. See FIG.

The cover 21 covering the upper surface of the main body 11 has a circular flat shape similar to the main body, and a space 23 is provided between the cover 21 and the upper surface.
And has an arch-shaped cross-sectional shape to enhance the structural strength, and only the outer portion 22 already touched contacts the receiving portion 17 of the main body 11. See FIG. Cover 2
1 has a concave portion 24 for accommodating the cap 15, and has an inner portion 25 for receiving the cap 15 in the center thereof. See FIG. 3 and FIG. The inner portion 25 is provided such that a gap 26 is maintained between the cap 15 and the main body 11 in a state where the cap 15 is fully mounted by fully tightening the screw as the coupling means 13 (FIG. 7). FIG. 7 shows that there is not only a gap 26 in the vertical direction but also a gap 27 in the inside and outside directions.

Therefore, even if the cap 15 is tightened and the packing 28 is pressed against the end of the pouring port 12, the cover 21 does not press the main body 11 at the inner part, so that the arch-shaped cross section is formed. Body 1 with cover 21 having
1 is strengthened. When the hot water in the main body is cooled, the main body 11 is also deformed, but this deformation is restored by adding the hot water. The amount of deformation of the main body 11 is the same on the upper surface and the lower surface without the cover 21, but the deformation is significantly reduced by combining the cover 21. 10 total deformation
Then, the deformation amount of the upper surface portion is 0 to 2 and the deformation amount of the lower surface portion is 10 to 8. In the figure, reference numeral 29 denotes a vent formed in the cover 21. The uneven shape of the cover 21 based on the central recess 24 improves the strength of the cover 21, whereby the tightening force of the cap 15 applied to the inner portion 25 is transferred from the outer portion 22 to the main body 11. I can tell it reliably.

[0020]

Since the present invention has the above-described structure and functions, the structure of the main body is significantly strengthened by the cover. Combined with the smooth structure of the main body, the hot water bottle can always be used comfortably without falling into an unrecoverable state. In addition, since the abutment portion of the main body is provided with an inclined component, the cover can be stably set in any state in which the cover is detached, so that the cover can be easily detached.
