Description

  The present invention relates to an aerosol container shoulder cover that is attached to an aerosol container and accommodates a mounting cup of the container inside, and in particular, two kinds of contents are separately contained in one container and each content is accommodated. The present invention relates to a shoulder cover of an aerosol container having a total of two stems to be discharged.

  Conventionally, as an aerosol container for storing a two-component type hair dye or hairdressing agent, one cylindrical container in which one content is stored in one cylindrical container and the other contents are stored. A double aerosol container is known which is arranged in a pair with the container on the left and right. Such a double aerosol container is provided with a nozzle that is connected to the stem of each container and discharges the contents discharged from each stem from one dispensing cylinder. For the purpose of holding and enhancing the decorative effect, it is usual to provide a shoulder cover that covers the mounting cup of the container. In such a double aerosol container, the entire cross-sectional shape of the container is a track shape, and the outer shape of the shoulder cover is also a track shape corresponding to this, so when attaching the shoulder cover to the container, On the other hand, since it can be aligned only by confirming only the front-rear direction, it is a relatively simple operation.

  Recently, regarding such a two-liquid type aerosol container, for example, as shown in Patent Document 1, two kinds of contents are separately accommodated in one container and an aerosol container having two stems is used. Opportunities are increasing. Here, this type of container has a circular cross-sectional shape of the entire container, while the two stems have irregularly-shaped portions having a long side and a short side in the cross-sectional shape provided on the mounting cup (for example, They are arranged side by side in the shape of an ellipse or a track). For this reason, when mounting the shoulder cover, it is necessary to align the container with the container so as to avoid interference with the two stems. However, since the outer shape of the shoulder cover is circular corresponding to the container, it is not possible to align both external shapes as a clue, and the irregularly shaped part of the mounting cup and the irregularly shaped part provided on the shoulder cover Since it is necessary to match the orientation with the part corresponding to, there is a problem that it takes time to align the position at the time of wearing.

JP 2012-30886 A

  An object of the present invention is to solve such a problem, and the object of the present invention is to make positioning with respect to an aerosol container provided with two stems in one cylindrical container easier. A new shoulder cover for aerosol containers is being proposed.

The present invention is a shoulder cover for an aerosol container that has a claw portion that engages with a mounting cup of an aerosol container, and that is mounted on the container with the mounting cup inside.
The mounting cup has two stems projecting from the top wall and a cross-sectional shape of an upper part having a different shape having a long side and a short side, and a diameter that is substantially the same length as the long side. A middle cylindrical portion connected to the middle cylindrical portion, and a lower cylindrical portion having a diameter larger than that of the middle cylindrical portion and coupled to the middle cylindrical portion and engaging the claw portion,
An inner peripheral wall extending downward from the top wall is integrally connected to the top wall of the shoulder cover,
The lower end portion of the inner peripheral wall includes an annular wall that is integrally connected via a weakened portion and has an inner peripheral surface shape along the outer peripheral surface of the upper step portion,
When the shoulder cover is placed on a mounting cup, the annular wall has a lower end portion that comes into contact with the top wall at a position where the claw portion is above the lower cylindrical portion. Shoulder cover.

  It is preferable that the weakened portion is a thin wall that is thinner than the inner peripheral wall and the annular wall.

  It is preferable that the weakening part is a plurality of connecting pieces that are provided at intervals along the circumferential direction of the annular wall and that intermittently connect the inner peripheral wall and the annular wall.

  The shoulder cover of the present invention has two stems projecting from the top wall and an upper step portion having a different cross-sectional shape having a long side and a short side and a diameter substantially the same length as the long side. The ceiling wall of the shoulder cover with respect to the mounting cup comprising a middle cylindrical portion coupled to the lower cylindrical portion that has a larger diameter than the middle cylindrical portion and is coupled to the middle cylindrical portion and engages the claw portion of the shoulder cover The inner peripheral wall extending downward is integrally connected, and an annular wall having an inner peripheral surface shape along the outer peripheral surface of the upper step portion is provided at the lower end portion of the inner peripheral wall via the weakened portion. When the shoulder cover is placed on the mounting cup on the annular wall, a lower end portion is provided in which the claw portion comes into contact with the top wall at a position above the lower cylindrical portion. As a result, when the shoulder cover is placed on the aerosol container, the annular wall of the shoulder cover that comes into contact with the top wall of the upper part of the mounting cup rotates the shoulder cover so that the upper part and the annular wall are aligned. , Move down to the middle cylindrical part. That is, even if the shoulder cover is placed without worrying about the orientation of the shoulder cover, if the shoulder cover is rotated, the height of the shoulder cover will be lowered when both positions are matched. It is possible to know that the positioning of the cover has been completed. In addition, since the annular wall is integrally connected to the shoulder cover via the weakened portion, if the shoulder cover is pressed from above after the positioning is completed, the annular wall can be broken from the weakened portion. Thereby, although the annular wall for positioning is provided, the height of the shoulder cover after mounting is the same as the case where it is not provided, so that the size is not increased.

  The weakened portion is constituted by a thin wall thinner than the inner peripheral wall and the annular wall, or a plurality of connecting pieces that are provided at intervals along the circumferential direction of the annular wall and intermittently connect the inner peripheral wall and the annular wall. In this case, since the configuration of the weakened portion is simplified, the manufacturing cost is not increased.

  1 (b) and 1 (c), reference numeral 1 denotes an aerosol container (hereinafter sometimes simply referred to as “container”) to which the shoulder cover of the present invention is attached. The container 1 is a cylindrical container body 2 made of metal, for example, and the outer edge of a metal-made mounting cup 3 is fixed by tightening or the like, and two types of contents are accommodated separately inside. Has been. The container 1 also has a total of two stems 4 connected to the storage spaces for the respective contents.

  At the center of the mounting cup 3, a stem 4 protrudes from the top wall 3a, and as shown in FIG. 1 (a), an upper step 3d having a different cross-sectional shape having a long side 3b and a short side 3c. A middle cylindrical portion 3e having a diameter D1 having substantially the same length as the long side 3b and connected to the upper step portion 3d, and a lower step having a diameter D2 larger than the diameter D1 of the middle cylindrical portion 3e and connected to the middle step cylindrical portion 3e. A cylindrical portion 3f is provided. Here, the “long side” is a portion having the longest length between two opposing sides in the cross-sectional shape of the upper step portion 3d, and the “short side” is opposed in the cross-sectional shape of the upper step portion 3d. The part where the length between two sides is the shortest. That is, “an irregular shape having a long side and a short side” means a shape excluding a circular shape, and indicates, for example, a rectangular shape, a track shape, or an elliptical shape. In the present embodiment, the upper step portion 3d is formed in a track shape as shown in FIG. 1A, and the stems 4 are arranged in a line along the long side 3b. As shown in FIGS. 1B and 1C, the height of the top wall 3a with reference to the bottom of the container body 2 (not shown) is Ha, and the upper surface of the middle cylindrical portion 3e with reference to the bottom Let the height be Hb.

  Moreover, in Fig.1 (a)-(c), the code | symbol 10 shows one Embodiment of the shoulder cover of this invention. The shoulder cover 10 refers to the one that can be mounted on the container 1 with the mounting cup 3 inside, and can be directly seen from the outside as in this embodiment and used as an exterior product, as well as another cover. In general, a fixed platen that can be attached to the outside is also included. Here, the shoulder cover 10 of the present embodiment has a top wall 11 having a disk shape, and extends downward while slightly curving radially outward from the outer edge portion of the top wall 11 and the container body 2. A cylindrical outer peripheral wall 12 is provided. In the present embodiment, a track-shaped opening 13 is provided at the center of the top wall 11, and an inner peripheral wall 14 extending downward is provided at the edge of the opening 13. Further, an annular wall 16 is integrally connected to the lower end portion of the inner peripheral wall 14 via the weakened portion 15 and the inner peripheral surface thereof has a shape (track shape in the present embodiment) along the outer peripheral surface of the upper step portion 3d. Provided. 1B and FIG. 1C, the part indicated by reference numeral 16a is the lower end portion of the annular wall 16.

  The weakened portion 15 is a portion that is weaker than the inner peripheral wall 14 and the annular wall 16. For example, the weakened portion 15 may be configured as a thin wall having a smaller thickness than the inner peripheral wall 14 and the annular wall 16, or may be provided at intervals along the circumferential direction of the annular wall 16. It is also possible to configure as a plurality of connecting pieces that connect the annular wall 16 intermittently. It is also possible to integrally connect these materials by using a material having a weaker strength than the inner peripheral wall 14 and the annular wall 16, for example, by two-color molding. The configuration can be used as appropriate.

  Further, the shoulder cover 10 extends downward from the top wall 11 between the outer peripheral wall 12 and the inner peripheral wall 14, and the diameter of the inner peripheral surface thereof is substantially the same as the lower cylindrical portion 3 f of the mounting cup 3. And a claw portion 18 projecting radially inward, and a slit 19 (FIG. 1 (FIG. 1) partially cut away from the cylindrical wall 17). b)).

  In mounting the shoulder cover 10 having the above configuration on the container 1, the shoulder cover 10 is placed on the mounting cup 3 of the container 1. Here, when the directions of the container 1 and the shoulder cover 10 do not match, as shown in FIG. 1B, the lower end portion 16a of the annular wall 16 is connected to the top wall 3a (height Ha) of the upper step portion 3d. ). Further, in this state, the claw portion 18 is located above the lower cylindrical portion 3f.

  Thereafter, the shoulder cover 10 is rotated with respect to the container 1. As described above, since the claw portion 18 is located above the lower cylindrical portion 3f, the shoulder cover 10 rotates without resistance. When the orientation of the upper step portion 3d and the annular wall 16 is matched, as shown in FIGS. 2A to 2C, the annular wall 16 is fitted into the upper step portion 3d, and the lower end portion 16a thereof is a middle cylinder. It moves to the upper surface (height Hb) of the part 3e. That is, it is possible to know that the positioning of the shoulder cover 10 has been completed by reducing the height of the shoulder cover 10 by (Ha−Hb).

  After that, when the shoulder cover 10 is pressed from above, as shown in FIGS. 3A to 3C, the annular wall 16 is broken from the weakened portion 15, and the claw portion 18 of the cylindrical wall 17 is the lower cylindrical portion. The shoulder cover 10 is retained by the container 1 by being engaged with 3f. Since the annular wall 16 is connected over the entire circumference, the rigidity is high and the shoulder cover 10 is not bent or bent when the shoulder cover 10 is pressed from above. Therefore, the annular wall 16 can be reliably broken from the weakened portion 15. . In addition, the cylindrical wall 17 is provided with a slit 19, and when engaged, the cylindrical wall 17 can be bent radially outward, so that the force required for engagement does not increase that much. As described above, the annular wall 16 functions in the alignment of the shoulder cover 10. On the other hand, when the shoulder cover 10 is held in the container 1, the annular wall 16 breaks from the weakened portion 15 and enters the shoulder cover 10. Therefore, it is possible to suppress the height to the same level as when the annular wall 16 is not provided.

  After that, although not shown in the figure, a nozzle is prepared which is connected to each of the two stems 4 and has one pouring tube connected to each of them, and this nozzle is connected to the stem 4 through the opening 13 of the shoulder cover 10. To do. If the nozzle is pressed from above, two types of contents in the container 1 can be discharged simultaneously.

  According to the present invention, since it can be easily positioned with respect to an aerosol container having two stems, a new shoulder cover for an aerosol container that facilitates assembly work can be provided.
