考案の分野
本考案はまほうびん等液体容器の底構造、特に
液体容器を床面上に回動自在に載置し得るように
したいわゆる回転底構造に関するものである。[Detailed Description of the Invention] Field of the Invention The present invention relates to a bottom structure for liquid containers such as magic bottles, and in particular to a so-called rotating bottom structure that allows the liquid container to be rotatably placed on the floor. .
従来技術とその問題点
従来、この種の底構造に用いられる回転体とし
ては、第4図、第5図に示す2種のものが知られ
ている。即ち、第4図の場合には、回転体20の
内周部に内向きの掛止受部21を立設し、この掛
止受部21を底体下面に設けた外向きの掛止爪に
係合させるとともに、上記掛止受部21の外側に
上面に摺動溝23を有する倒U字形の厚肉部22
を設けたものである。また、第5図の場合には、
回転体24の内周部に掛止受部25を立設し、掛
止受部25の外側に凹状載置部26を形成すると
ともに、載置部26上面に摺動突起27を突設し
たものである。Prior Art and Problems Conventionally, two types of rotating bodies shown in FIGS. 4 and 5 are known as rotating bodies used in this type of bottom structure. That is, in the case of FIG. 4, an inwardly facing latch receiving part 21 is provided upright on the inner periphery of the rotary body 20, and this latch receiving part 21 is formed into an outwardly facing latch claw provided on the bottom surface of the bottom body. an inverted U-shaped thick wall portion 22 having a sliding groove 23 on the upper surface on the outside of the latch receiving portion 21;
It has been established. Also, in the case of Figure 5,
A latching receiving part 25 is provided upright on the inner peripheral part of the rotating body 24, a concave placing part 26 is formed on the outside of the latching receiving part 25, and a sliding protrusion 27 is protruded from the upper surface of the placing part 26. It is something.
上記いずれの場合も、掛止受部21,25の外
側に摺動溝23や摺動突起27が設けられている
ため、回転体20,24の径方向の厚みtが大き
くなつて断面形状が大型化し、部品重量が重くな
る欠点がある。 In any of the above cases, since the sliding grooves 23 and the sliding protrusions 27 are provided on the outside of the latching receivers 21 and 25, the radial thickness t of the rotating bodies 20 and 24 increases and the cross-sectional shape becomes smaller. The disadvantage is that it becomes larger and the weight of the parts becomes heavier.
そこで、上記回転体20,24の肉厚を薄くす
れば重量を軽減でき、材料コストも低減できる
が、反面、強度が著しく低下する欠点がある。特
に、回転体には液体容器の全重量が作用するた
め、単に肉厚を薄くしただけでは回転体が座屈し
てしまい、回転体本来の機能を損なうことにな
る。 Therefore, by reducing the thickness of the rotating bodies 20 and 24, the weight and material cost can be reduced, but on the other hand, there is a drawback that the strength is significantly reduced. In particular, since the entire weight of the liquid container acts on the rotating body, simply reducing the wall thickness will cause the rotating body to buckle, impairing its original function.

本考案はかかる従来の問題点に鑑みてなされた
もので、その目的は、回転体の断面形状を小さく

とにある。Purpose of the invention The present invention was made in view of the problems of the prior art, and its purpose is to reduce the weight of parts by reducing the cross-sectional shape of the rotating body, and to create a liquid container that does not impair the original function of the rotating body. The purpose is to provide a bottom structure.

摺動突起6が下方へ突設されている。DESCRIPTION OF EMBODIMENTS FIGS. 1 and 2 show an example in which the bottom structure of the present invention is applied to a magic bottle. A medium bottle 2 is housed inside a container body 1, and the bottom of the medium bottle 2 is The bottom body 3 tightens and supports it. On the lower surface of the bottom body 3,
An annular wall 5 having a plurality of latching claws 4 is vertically provided on the outer surface of the tip, and a plurality of sliding protrusions 6 are provided on the outside of the annular wall 5 to project downward.
一方、7は樹脂製の回転体で、この回転体7は

1とで構成されている。 On the other hand, reference numeral 7 denotes a rotating body made of resin, and as shown in FIG. , a mounting surface 9 formed on the lower surface of this vertical wall 8
, a latching receiver 10 protruding inward from the inner surface of the upper end of the vertical wall 8, and a sliding groove 1 formed on the upper end surface of the vertical wall 8.
It consists of 1.

2の割れを防止できる。 The rotating body 7 is rotatably attached to the lower surface of the bottom body 3 by forcibly engaging the hooking receiving portion 10 with the hooking pawl 4 of the bottom body 3. When the container body 1 is placed on the floor surface, the mounting surface 9 of the rotating body 7 comes into contact with the floor surface, and the sliding protrusion 6 of the bottom body 3 can freely slide on the sliding groove 11. can be rotated freely. Note that since the contact point between the sliding groove 11 and the sliding protrusion 6 and the contact point between the mounting surface 9 and the floor surface are slightly shifted in the radial direction, the container body 1 may not be roughly placed on the floor surface. Even if the bottle 2 is placed on the inside, the impact load applied to the sliding groove 11 can be absorbed by the deflection of the vertical wall 8, and the inner bottle 2 can be prevented from cracking.
上記のように、掛止受部10と摺動溝11とを
縦壁8の付近に設けたので、回転体7の径方向の

く、よつて容器本体1を床面上に載置したとき傾
くことがない。 As described above, since the latch receiving portion 10 and the sliding groove 11 are provided near the vertical wall 8, the radial thickness t of the rotating body 7 can be reduced, and the cross-sectional shape can be reduced accordingly. By the way, to reduce the cross-sectional shape,
This can be achieved by reducing the height in the vertical direction instead of reducing the thickness in the radial direction, but in this case the rotating body becomes flat and easily twists during resin molding, making it difficult to obtain flatness. On the other hand, since the present invention has a cylindrical vertical wall 8,
There is no twisting during molding, and there is no fear that the flatness will be distorted, and therefore, the container body 1 will not tilt when placed on the floor.

は、底体3側に摺動溝を設ければよい。 FIG. 3 shows another embodiment of the rotating body 7 according to the present invention, in which a plurality of sliding protrusions 12 are provided protruding from the upper end surface of the vertical wall 8 instead of the sliding grooves. In this case, a sliding groove may be provided on the bottom body 3 side.

Since it is composed of a protruding latch receiving part and a sliding groove or sliding protrusion formed on the upper part of the vertical wall, the thickness of the rotating body in the radial direction can be reduced, and the cross-sectional shape of the rotating body can be reduced. It can be made smaller and the weight of parts can be reduced. Also,
Since the vertical wall prevents the rotating body from buckling and twisting during molding, the strength and flatness of the rotating body are not impaired. Furthermore, the annular wall and sliding protrusion of the bottom body can be made to have the minimum dimensions.
