Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a portable liquid container such as a portable thermos flask.

(Prior art and its problems) A cushion ring is attached to the end of a liquid container, for example, around the outer circumference of a tip that is removably screwed onto the end of the liquid container, to reduce the impact that is applied when the liquid container is dropped, and to protect the internal and It has been conventional practice to protect the outer case. However, conventional ones use cushion rings that protrude outward from the side circumferential surface of the tip to cushion the impact in the left and right direction, or cushion rings that protrude vertically from the end surface of the tip. The former had a problem in that it had no vertical cushioning effect, and the latter had no horizontal cushioning effect.

(Purpose of the invention) In view of the above, the present invention includes a cushion ring that is screwed onto the end of a liquid container and is capable of acting as a cushion against impacts in both the vertical and horizontal directions. The corner part on the outer periphery of the end surface protects the internal structure and exterior case from the shock that is applied when falling or colliding with other objects. The purpose is to provide a good portable liquid container.

(Structure of the invention) In order to achieve the above object, the present invention has cushion rings 6 and 7 attached to the corners of the outer periphery of the end surface of the tip 2 which is removably screwed onto the end of the liquid container. 6 and 7 protrude from the end surfaces and outer peripheral surfaces of the tips 2 and 3, respectively, and
A space S is provided between the outer circumferential side surface of the cushion ring 3 and the side circumferential portions of the cushion rings 6 and 7.

(Embodiment) The embodiment shown in FIG. 1 relates to a portable thermos flask, and the container body 1 includes an outer case 10, a shoulder ring 11, a lower opening member 12, a bottom member 13, and an inner bottle 14.
It is mainly composed of.

The shoulder ring 11 is screwed and fixed to the upper end of the outer case 10, and the lower mouth member 12 is supported by the shoulder ring 11 via a rubber ring member 15 for cushioning. A bottle opening 17 of a medium bottle 14 made of a vacuum double glass bottle is in contact with the lower surface of the lower opening member 12 via a rubber bottle opening packing 16. Further, the lower mouth member 12 has a beak-shaped water injection part 18, and
It has a cylindrical portion 19 extending downward. This cylindrical portion 19 has a protective cover 20 for holding the medium bottle 14.
is screwed at its upper end.

The bottom member 13 is screwed and fixed to the lower end of the outer case 10, and a cap-shaped cushion member 22 is attached to the lower end protrusion 21 of the protective cover 20 at the center of the bottom.
It has a recessed portion 23 that is held through.

A stopper 24 is removably screwed onto the lower mouth member 12, thereby closing the bottle mouth 17. As shown in FIG. 1, the stopper body 24 is provided with a water injection passage 25 that can be opened and closed even when the stopper is set in the closed state. Also, this water injection passage 25
One-touch opening/closing mechanism 27 on push button 26
It is opened and closed by a valve body 28 which is connected through the valve body 28.
This one-touch opening/closing mechanism 27 is as disclosed in Japanese Utility Model Application Publication No. 58-3134.
6 and the valve body 28, the rotary type actuating cylinder 2
9, a return spring 30, etc. are arranged. The first push of the push button 26 sets the valve body 28 to the open position and maintains it there, and the second push returns the valve body 28 to the close position. configured to be maintained.

The shoulder ring 11 is provided with a string hooking part 31, and a threaded screw 32 for screwing is formed on the outer periphery of the upper part thereof. The bottom member 3 is also provided with a string hooking part 33, and a screw 3 for screwing the bottom part is provided on the outer periphery of the lower part.
4 is formed. Both ends of a shoulder strap (not shown) are hooked to both strap hooks 31 and 33, making it convenient to carry.

The shoulder ring 11 is removably screwed onto the shoulder ring 11 using the screw 32 thereof. 35 is a screw provided on the inner periphery of the mouth of the tip 2, and is screwed into the screw 32. A cushion ring 6 made of rubber is fitted into the edge of the bottom surface 4 of the cup 2 (the edge of the outer periphery of the upper end of the liquid container). 36 and 37 are the tips 2 for fitting the cushion ring 6.
This is a fitting groove provided in the This cushion ring 6
As shown in FIG. 1, is formed in a shape that protrudes above the bottom surface (upper end surface of the liquid container) 4 by a predetermined amount Q and also protrudes laterally by a predetermined amount P from the outer circumferential side surface 8. A space S is provided between the outer circumferential side surface of the tip 2 and between the top thereof and the upper end surface of the tip 2.

A top 3, which is exactly the same as the top 2, is removably screwed onto the bottom member 3 using the screw 34 thereof. This tip 3 is the same screw 3 as above.
8. It has fitting grooves 39 and 40, and a cushion ring 7 similar to the above is fitted into the corner part of the outer periphery of the bottom surface 5 (the corner part of the outer periphery of the lower end of the liquid container). Further, the cushion ring 7 is inserted by a predetermined amount Q, P from the bottom surface (lower end surface of the liquid container) 5 and the outer circumferential side surface 9.
Similarly to the above case, a space S is provided between the protruding side circumferential portion and the outer circumferential side surface of the tip 3 and between its lower part and the lower end surface of the tip 2.

In the embodiment shown in FIG. 2, a cushion ring 6 having a slightly different shape from the cushion ring 6 of the above-mentioned embodiment is fitted onto the tip 2. In this case as well, the cushion ring 6 is fitted onto the tip 2. It is formed so that it protrudes from the bottom surface 4 and the outer circumferential side surface 8 by predetermined amounts Q and P, respectively, and a space S is provided between it and the side circumference of the tip 3. Numerals 41, 42, and 43 are fitting grooves provided in the tip 2 for fitting the cushion ring 6 thereinto. Although FIG. 2 shows the upper tip 2 and cushion ring 6, the lower tip 3 and cushion ring 7 are also of exactly the same construction. In this embodiment, the structure of the stopper 24 is slightly different from that of the above embodiment, but its basic function is the same. 44 is a heat insulating material built into the valve body 28;
45 is a seal gasket provided on the seating portion of the valve body 28.

The present invention can be configured in various ways other than those shown in the above embodiments, and can be applied to portable liquid containers other than portable thermos flasks, for example.

(Effect of the invention) The invention has a cushion ring that is shaped to protrude from the end face and the outer peripheral side of the liquid container, respectively, on each corner of the outer periphery of the tip that is removably screwed onto the end of the liquid container. Therefore, the cushion ring can exert an effective cushioning action regardless of whether the direction of the impact when the portable liquid container falls or collides with another object is in the up, down, left, or right direction. This has the effect of protecting the internal structure and the outer case.

In addition, since there is a space between the outer circumferential side of the tip and the side circumference of the cushion ring, the cushion ring will fit better in your hand when you place your hand on the corner of the tip to open or close it. Make it easier or
In addition, since the space functions as a heat insulating space, when you pick up the tip, combined with the heat insulating properties of the cushion ring itself, it also has the effect of preventing your hands from getting hot.
