  The present invention will be described below with reference to the drawings. First, with reference to FIG.1 and FIG.2, the tube container 2 used with the kneading apparatus 1 which concerns on this invention is demonstrated. As shown in FIG. 1, the tube container 2 is sealed by a cap 3, and has a spout 2 a on one end side and a thin-walled, cylindrical (round or oval) barrel portion 2 b that accommodates an object to be kneaded 4. And an opening 2c or a seal portion 2d on the other end side, and a resin tube made of a soft resin such as PE or an aluminum tube made of soft aluminum.

  First, as shown in FIG. 1A, the tube container 2 has an opening 2c formed at the other end, and the material to be kneaded 4 is injected from the opening 2c. And in 1st Embodiment mentioned later, the tube container 2 of the state which opened the other end side and accommodated the to-be-kneaded material 4 is set to the kneading apparatus 1, kneading | mixing of this to-be-kneaded material 4 is performed, and this kneading | mixing is performed. After that, the other end side is crushed flat, and in the case of a resin tube, it is welded by heat, high frequency, etc., and in the case of an aluminum tube, as shown in FIG. A seal portion 2d is formed and sealed on the end side, and the tube container 2 is provided to the user. On the other hand, in a second embodiment to be described later, the tube container 2 in a state where the other end side is sealed in advance and the material to be kneaded 4 is accommodated is set in the kneading apparatus 1, and the material to be kneaded 4 is kneaded, After the kneading is performed, the tube container 2 is provided to the user. In the following, the tube container 2 in the state shown in FIG. 1 (a) is referred to as “first tube container 2”, and the tube container 2 in the state shown in FIG. 1 (b) is referred to as “second tube container 2”. Called.

  As shown in FIG. 1C, a screw is formed on the outer periphery of the spout 2a on one end side of the tube container 2, and a screw is also formed on the inner periphery of the cap 3, so that both screws are screwed.

Further, the cap 3 is formed with a convex portion 3a that is inserted into the spout 2a when the spout 2a is sealed, and prevents the material to be kneaded 4 from leaking during kneading. Yes.

  As shown in FIG. 2, the tube container 2 used in the present invention has three types of sizes depending on the capacity. The outer diameter is 25 mm to 50 mm, and the length is twice the outer diameter. It has been confirmed by a demonstration experiment that it is preferable to set the ratio to 3 times. As described above, the tube container 2 used in the present invention has a relatively large diameter (so-called so-called cylindrical shape) with respect to the existing tube container, which is a small diameter (for example, about 10 mm) like the existing tube container. This is because the material to be kneaded 4 containing a base such as white petrolatum having a high viscosity cannot be kneaded (that is, stirring and defoaming are not sufficiently performed). Moreover, in the tube container 2 used by this invention, it is preferable that the limit amount of the to-be-kneaded material 4 shall be half or less of a capacity | capacitance. This is because when the amount of the material to be kneaded 4 exceeds half of the capacity, sufficient kneading cannot be performed.

  Next, the basic structure of the kneading apparatus 1 according to the present invention will be described with reference to FIG. The kneading apparatus 1 includes a support 11 that is horizontally supported via an elastic body such as a spring in a housing (not shown), a revolving shaft 12 that protrudes vertically from the support 11, and the revolving shaft 12 passes therethrough. A connecting body 12a that is rotatable with respect to the supporting body 11, a rotating body 13 that is fixed to the upper part of the connecting body 12a with the centrifugal side inclined toward the revolving shaft 12 (here, inclined by 45 ° with respect to the horizontal), and a support The motor 14 fixed to the lower side of the body 11, the first gear 14a fixed to the rotating shaft of the motor 14 that penetrates the support 11, and the first gear 14a meshing with the outer periphery of the connection body 12a. A second gear 14b, a third gear 15 coaxially fixed to the upper portion of the revolving shaft 12 penetrating the rotating body 13, and a pair of fourth gears meshed with the third gear 15 and rotatable relative to the rotating body 13. 16 and 16 and fixed to the top of each fourth gear 16 and 16 coaxially. A pair of bevel gears 17, 17, a pair of rotation shafts 18, 18 that are inclined toward the revolving shaft 12 and are rotatable with respect to the inclined portion of the rotating body 13, and the bevel gears 17, 17 mesh with each rotation shaft. A pair of fifth gears 19, 19 that are coaxially fixed to the upper portions of 18, 18 and rotatable relative to the rotating body 13, and are coaxially fixed to the upper portions of the fifth gears 19, 19 to the rotating body 13. And a pair of freely rotatable container holders 20, 20.

  In the kneading apparatus 1, when the motor 14 rotates, the first gear 14a, the second gear 14b, and the connecting body 12a rotate, so that the rotating body 13 rotates around the revolution shaft 12, and the rotating body 13 When rotating, the second gear 16 meshing with the stationary first gear 15 rotates, and the bevel gear 17 and the third gear 19 rotate, whereby the container holder 20 rotates around the rotation shaft 18, and the container holder The container held inside 20 revolves on its revolving trajectory while revolving. As a result, centrifugal force acts on the material to be kneaded in the container due to the revolution of the container, the material to be kneaded is pressed against the inner wall of the container by the centrifugal force, and the material to be kneaded in the container is further rotated by the rotation of the container. Stir and knead.

  In the example shown in FIG. 3, the example in which the rotation of the motor 11 is transmitted to the rotating body 13 and the container holder 20 via a gear has been described. However, the rotation of the motor 11 is transmitted to the rotating body 13 and the container holder via a belt. 20, or a motor that directly rotates the rotation shaft 18 without providing a mechanism for transmitting the rotation of the motor 11 to the container holder 20. That is, the basic structure of the kneading apparatus 1 is “a rotating body 13 that rotates around a vertical revolution shaft 12, and a rotation shaft 18 that is provided on the centrifugal side on the rotating body 13 and that tilts toward the revolution shaft 12. A container holder 20 that rotates and revolves the container held inside the container holder 20 so that the material to be kneaded contained in the container is stirred and degassed to knead " Well-known or various known kneading apparatuses (so-called rotation / revolution mixers) can be applied.

  Next, with reference to FIG.4 and FIG.5, the characteristic structure of the kneading apparatus 1 which concerns on this invention is demonstrated. In addition, the hatching which should be attached | subjected respectively to the cross section of the spout 2a, the cap 3, and the container holder 20 in Fig.5 (a), and the cross section of the trunk | drum 2b and the container holder 20 in FIG.5 (b) is complicated to illustrate. It is omitted to avoid becoming.

  This characteristic structure is “a tube container holding mechanism for holding the tube container 2 inside the container holder 20 coaxially with the rotation shaft 18 so as to rotate together with the container holder 20”. Here, as the tube container holding mechanism, The adapter 30 is fixed by being fitted inside the bottomed cylindrical container holder 20.

  As shown in FIG. 4, the adapter 30 is molded from resin or the like and has a bottomed cylindrical shape. As shown in FIG. 5A, a hexagonal recess 30a is formed at the center of the inner bottom. The inner wall 30b has a hexagonal shape as shown in FIG. By fitting the hexagonal cap 3 into the hexagonal recess 30a, the tube container 2 rotates coaxially with the adapter 30 and the container holder 20 (that is, does not idle), so that it is coaxial with the rotation shaft 18. It is held inside the container holder 20. Further, since the inner wall 30b of the adapter 30 is formed in a hexagonal shape, the barrel portion 2b of the tube container 2 is deformed along the shape of the inner wall 30b by centrifugal force during revolution and rotation. Can be suppressed.

  In this example, three types of adapters 30 corresponding to each of the three types of tube containers 2 are prepared so that a gap between the inner wall 30b of the adapter 30 and the outer wall of the tube container 2 held inside is not generated as much as possible. An adapter 30 corresponding to the tube container 2 to be used is fitted and fixed inside the container holder 20.

  Next, the operation of the kneading apparatus 1 according to the present invention will be described. First, the first embodiment using the first tube container 2 shown in FIG. 1A will be described. As shown in FIG. 4, the adapter 30 corresponding to the tube container 2 is fitted into the container holder 20.

When the motor 11 (see FIG. 3) is rotated and the tube container 2 held inside the container holder 20 revolves on its revolving track while revolving as described above. The material to be kneaded 4 accommodated in the tube container 2 is stirred and defoamed at a position as shown in the figure and kneaded. In the first embodiment, since the other end portion of the tube container 2 is opened, the trunk portion 2b of the tube container 2 is circular from the top to the bottom. Kneading is performed. Then, after the kneading is finished, as shown in FIG. 1 (b), the opening 2c of the tube container 2 is sealed to form a seal portion 2d, which is provided to the user. In addition, the user can open the cap 4 and take out the material 4 to be kneaded from the spout 2 a, so that germs do not enter the tube container 2.

  Next, a second embodiment using the second tube container 2 shown in FIG. 1B will be described. As shown in FIG. 4, an adapter 30 corresponding to the tube container 2 is fitted inside the container holder 20. The hexagonal cap 3 screwed into the spout 2a is attached to the hexagon of the adapter 30 with the spout 2a of the tube container 2 containing the material 4 to be kneaded facing downward. When the motor 11 (see FIG. 3) is rotated by fitting in the concave portion 30a of the shape, the tube container 2 held inside the container holder 20 rotates on its revolving track while revolving as described above. Then, the material to be kneaded 4 accommodated in the tube container 2 is stirred and defoamed at a position as shown in the figure and kneaded. In the second embodiment, since the other end portion of the tube container 2 is sealed by the seal portion 2d, the body portion 2b in the vicinity of the seal portion 2d is crushed and flattened. Although the kneading conditions are inferior to those of the embodiment, necessary and sufficient kneading is performed. On the other hand, since the other end portion of the tube container 2 is sealed by the seal portion 2d, scattering of the material to be kneaded 4 during kneading is prevented. By providing to the user after the kneading is finished, it is possible to suppress oxidation and deterioration of the material to be kneaded 4 due to air contact, and the user opens the cap 4 and takes out the material 4 to be kneaded from the spout 2a. No germs enter the tube container 2.
