Hereinafter, the structure and function of the plurality of reinforcing ribs 25 provided on the container body 2 will be described in detail.
The container body 2 is formed by integrally molding a neck portion 2c, a shoulder portion 2d, a trunk portion 2e, and a bottom portion 2f with resin. In the present embodiment, the container body 2 is formed of polyethylene terephthalate (PET). The manufacturing process of the container body 2 includes a preform manufacturing process by injection molding of resin and a process of manufacturing the container body 2 by blow molding the preform. The plurality of reinforcing ribs 25 are formed at the time of blow molding, and are formed on the body portion 2e of the container body 2 in a shape along the inner shape of the mold.

  The container body 2 having the body portion 2e having a substantially elliptical cross section as in the present embodiment has a lower mechanical strength (hereinafter referred to as a dent strength) that can withstand a dent against an external pressure than a cylindrical container. . In other words, in the present embodiment, the first curved wall portions 21 and 23 having a relatively large curvature intersecting the elliptical long axis, and the second curved wall portion 22 having a relatively small curvature intersecting the elliptical short axis. , 24 has a low dent strength. For this reason, when the inside of the container main body 2 has a negative pressure, the second curved wall portions 22 and 24 having a low dent strength are easier to dent than the first curved wall portions 21 and 23.

  Therefore, in the present embodiment, a plurality of reinforcing ribs 25 are provided on the second curved wall portions 22 and 24 that are easily recessed. On the other hand, the reinforcing ribs 25 are not provided on the first curved wall portions 21 and 23 having relatively high dent strength. In this way, by providing the reinforcing ribs 25 only on the second curved wall portions 22 and 24, it is possible to make the dent strength uniform for the entire container, and to eliminate the dent-prone portions when the inside becomes negative pressure. The occurrence of dents as a whole container can be suppressed. Further, the first curved wall portions 21 and 23 not provided with the reinforcing ribs 25 are assigned with a boundary for separating the mold at the time of blow molding, so that the boundary portions are not positioned on the reinforcing rib 25 and the appearance is improved. Can do.

  Moreover, in this embodiment, the intensity | strength with respect to a dent is improved more by making all the reinforcement ribs 25 incline with respect to the central axis C of the container main body 2. FIG. In the present embodiment, all the reinforcing ribs 25 are inclined with respect to the central axis C at substantially the same inclination angle. The inclination angle of the reinforcing rib 25 with respect to the central axis C is related to the strength of the body portion 2e when the reinforcing rib 25 is provided, and is preferably 5 ° to 25 °, more preferably 10 ° to 20 °. By designing the inclination angle of the reinforcing rib 25 within this range, the strength against the dent of the container body 2 can be improved, and the container body 2 is attached when the cover portion 101 of the diffuser 100 is attached to the container body 2. The buckling strength with respect to the load which acts on can be improved. For this reason, in this embodiment, the inclination angle of the reinforcing rib 25 with respect to the central axis C is designed to be about 10 °.

  In the present embodiment, all the reinforcing ribs 25 provided on the second curved wall portions 22 and 24 of the container body 2 are inclined in the same direction along the circumferential direction. For this reason, it is not necessary to align the direction of the container at the time of product shipment, and the workability can be improved accordingly, and the manufacturing cost can be reduced. Further, when all the reinforcing ribs 25 are aligned in the same direction as in the present embodiment, when the container body 2 is viewed from the direction of FIG. 1, the five curved walls 24 provided on the back side are provided. The reinforcing ribs 25 intersect with the five reinforcing ribs 25 provided on the second curved wall portion 22 on the front side. In this way, the front reinforcing rib 25 and the rear reinforcing rib 25 intersect so that the liquid absorbent core 6 disposed at the center of the container body 2 can be made difficult to see, and the aesthetic appearance of the container can be improved. .

  In particular, in the present embodiment, five reinforcing ribs 25 are provided on each of the second curved wall portions 22 and 24. Therefore, when the container body 2 is viewed from the front (or the back), the central reinforcing rib 25a is the liquid absorption core. 6 is necessarily overlapped, and an effect of making the liquid absorbent core 6 difficult to see can be expected. That is, it is desirable to provide an odd number of reinforcing ribs 25 for each of the second curved wall portions 22 and 24. In this case, if the number of the reinforcing ribs 25 is increased, the dent strength can be increased, but an appropriate number of the reinforcing ribs 25 is provided in consideration of the thickness and size of the body portion 2e of the container body 2 or design. It is desirable to provide it.

  Furthermore, in this embodiment, in order to increase the dent strength of the second curved wall portions 22 and 24 of the body portion 2e, the lower ends 26a of the plurality of peripheral walls 26 between the two adjacent reinforcing ribs 25 are placed inside the container. The peripheral wall 26 itself was made strong by bending. On the other hand, in order to secure the internal volume of the container body 2, the upper ends 26b of the peripheral walls 26 are linear without being recessed inward. Thus, by making the upper end 26b of each peripheral wall 26 linear, when attaching the diffuser 100 to the medicine container 10 in a state where an exterior film (not shown) is wound around the body 2e, the exterior film is damaged. It can also be prevented. That is, the peripheral wall 26 between two adjacent reinforcing ribs 25 has a shape that gradually flattens from the lower end 26a toward the upper end 26b.

  The present invention has been described above based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the gist of the present invention. is there.

However, the present invention is not limited to this, and the present invention can also be applied to containers having other cross sectional shapes such as an oval cross section. In any case, it is only necessary to provide the reinforcing rib 25 in a portion where the strength of the container is low, and the inclination angle and the number of the reinforcing ribs 25 may be adjusted according to the shape and size of the container.

  In the above-described embodiment, the case where the inclination angles of the plurality of reinforcing ribs 25 are substantially the same has been described. However, the present invention is not limited thereto, and the inclination angles of the plurality of reinforcing ribs 25 may be varied depending on the arrangement position. Good. For example, the inclination angle with respect to the central axis C of the reinforcing rib 25a provided at the center of the second curved wall portions 22, 24 separated from the first curved wall portions 21, 23 is maximized, and then the outer side of the reinforcing rib 25a The inclination angle of the two reinforcing ribs 25b disposed adjacent to the first reinforcing wall 25b is increased, and the inclination angle of the two reinforcing ribs 25c closest to the first curved wall portions 21 and 23 (requiring little reinforcement) is minimized. can do. Thus, by providing a difference in the inclination angle according to the arrangement position of the reinforcing rib 25, the dent strength of the entire container can be made more uniform, and a container strong against the dent can be provided.

  Further, in the above-described embodiment, the case where the plurality of reinforcing ribs 25 are provided only on the two second curved wall portions 22 and 24 has been described. For example, one reinforcing rib 25 may be provided on at least one of the first curved wall portions 21 and 23 by increasing the interval between the ribs.
