Description

  The present invention relates to a rubber stopper fixing base for a medical bottle that fixes a rubber stopper that closes the mouth of the medical bottle.

  FIG. 5 is a perspective view showing a configuration of a conventional medicinal bottle.

  In FIG. 5, 1 is a medicinal bottle for storing a medicine or medicinal solution 2 and the like, 10 is a metal base that fixes a rubber stopper (see FIG. 10) that closes the mouth of the medicinal bottle 1, and 20 is a base. 10 is a synthetic resin lid member fixed to the upper surface of the base 10 while being attached to the base 10.

  6A and 6B are diagrams showing the configuration of the conventional base 10. FIG. 6A is a plan view showing the configuration of the upper surface portion 11 of the base 10 and FIG. 6B is a perspective view of the base 10. FIG.

  As shown in FIGS. 6 (a) and 6 (b), the base 10 is composed of a disc-shaped upper surface portion 11 and a cylindrical peripheral body portion 12, and a lid member 20 is fixed to the central portion of the upper surface portion 11. The through-hole 13 is provided. A cylindrical portion that can be engaged with the through hole 13 is formed on the back side of the upper surface portion of the synthetic resin lid member 30 shown in FIG. 5. By engaging this cylindrical portion with the through hole 13, The lid member 20 is fixed to the upper part of the base 10.

  In FIG. 6A, reference numeral 14 denotes a slit line that is thinner than the other parts of the upper surface part 11 or in a cut state. The slit 14 is not continuously formed, and a continuous portion 15 having the same thickness as the other portions of the upper surface portion 11 is provided in several places, and the integrity of the upper surface portion 11 is provided by the continuous portion 15. Is maintained.

  Further, as shown in FIG. 6B, the end portion of the slit line 14 of the upper surface portion 11 is formed so as to be connected to the two slit lines 16 formed in the peripheral body portion 12.

  The base 10 configured in this manner is such that the lower end portion of the peripheral body portion is fastened and fixed to the bottle mouth in a state of being crowned on the bottle mouth of the medicinal bottle 1 closed by the rubber stopper (see FIG. 10). .

  When using the chemical solution 2 stored in the medicinal bottle 1 configured as described above, when the user removes the lid member 20 from the state shown in FIG. As shown, in the process of removing the lid member 20, the upper surface portion 11 of the base 10 is cut along the slit muscle 14, and then the peripheral trunk portion 12 is cut along the slit muscle 16. Thus, the user is stored in the medicinal bottle 1 by removing the cap 10 cut along the tearing muscles 14 and 16 from the bottle mouth and removing the rubber stopper 3 closing the bottle mouth. Chemical solution 2 can be used.

  Here, depending on the type of the drug solution 2 or drug stored in the medicinal bottle 1, it must be sterilized for a certain period of time at high pressure and high temperature in the stage of shipping (the state shown in FIG. 5). There is. The conventional medicinal bottle 1 configured as shown in FIG. 5 cannot be used for such types of chemicals and drugs.

  The reason is that, when the sterilization treatment as described above is performed on the medicinal bottle 1 having the configuration shown in FIG. 5, the continuous portion 15 shown in FIG. 6 is destroyed in the course of the sterilization treatment, This is because, as shown in FIG. 8, the portion of the upper surface portion 11 of the base 10 surrounded by the cut line 14 is lifted. That is, if the inner side of the tearing bar 14 is lifted in this way, the pressing force against the rubber stopper 3 is lowered, and it becomes impossible to secure the sealed state of the bottle mouth by the rubber stopper 3.

  The reason why such a phenomenon occurs can be considered as follows.

  FIG. 9 is a view showing a state of the upper surface portion of the base 10 in the sterilization process under high pressure and high temperature. The AA sectional view is shown in FIG. 10 (a), and the BB sectional view is shown in FIG. 10 (b).

  During the sterilization process at a high temperature, the rubber plug 3 expands due to the heat. The degree to which this rubber plug 3 expands and deforms increases as it approaches the center of the rubber plug 3 as shown in FIGS. 10 (a) and 10 (b). Therefore, in the slit muscle 14 close to the through-hole 13 shown in FIG. 9, a large level difference occurs on both sides of the slit muscle 14, and as a result, a force is applied to the continuous portion 15 sandwiched between the slit muscles 14. In addition, the continuous portion 15 is destroyed, and it is considered that the phenomenon that the portion surrounded by the cut line 14 is lifted according to the deformation of the central portion of the rubber plug 3 occurs.

  As described above, the conventional medicinal bottle 1 having the structure shown in FIG. 5 has a problem that it cannot be sterilized.

  In order to solve the above problems, the present invention is a metal disk-like upper surface portion for fixing the rubber stopper in a state where the bottle stopper is attached to the bottle opening of the medicinal bottle closed by the rubber stopper. A cap for fixing a rubber cap of a reverse-bottomed cylindrical medicine bottle consisting of a cylindrical peripheral body portion, and is made of a synthetic resin that is fixedly attached to the base at the center of the upper surface portion of the base. A through hole for fixing the lid member is provided, and a penet-shaped continuous tear line of the fountain pen including the through-hole is formed on the upper surface portion of the base, and two of the pen-shaped base part are formed. The slit muscles are respectively connected to the two slit muscles formed in the peripheral body portion, and the thickness of the base in the pen-tip-shaped slit muscle is the same as the thickness of the slit muscle in the vicinity of the through hole. To be thicker than the thickness of the rest of the muscle And it is characterized in that it is selected.

  Here, the thickness between the portion of the slit muscle in the vicinity of the through hole and the other portion of the slit muscle selected so as to be thicker than the thickness of the other portion of the slit muscle. There may be provided a connection part in which continuously changes.

  According to the present invention, it is possible to provide a cap for fixing a rubber stopper of a medicinal bottle having a configuration in which a portion surrounded by a tear line on an upper surface portion does not float during a sterilization process.

It is a perspective view which shows the structure of Example 1 of this invention. It is a perspective view of a medicinal bottle equipped with Example 1 of the present invention. It is a top view which shows the structure of the upper surface part of Example 1 of this invention. It is explanatory drawing of a structure of Example 1 of this invention.

It is explanatory drawing of the usage method of the conventional medicinal bottle. It is explanatory drawing of the conventional medicinal bottle. It is explanatory drawing of the conventional medicinal bottle. It is explanatory drawing of the conventional medicinal bottle.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing a configuration of a first embodiment of the present invention, and FIG. 2 is a perspective view showing a configuration of a medicinal bottle 1 to which the first embodiment is attached. 1 and 2, the same reference numerals as those of the conventional example described above, that is, the conventional example shown in FIGS.

  The difference between the first embodiment and the conventional example is the configuration of the tearing bar 14 formed on the upper surface portion 11 of the base 10.

  The configuration of the slit muscle 14 will be described in detail with reference to FIGS. 3 and 4.

  FIG. 3 is a plan view showing the configuration of the upper surface portion 11 of the first embodiment. XX sectional view of FIG. 3 is shown in FIG. 4A, and YY sectional view of FIG. 3 is shown in FIG. 4B.

  As shown in FIG. 3, the slit line 14 on the upper surface portion 11 of the first embodiment is a slit line formed continuously unlike the conventional example. The shape of the fountain pen is a pen nib shape including the through-hole 13. The two slit muscles 14 at the base of the nib shape are connected to the two slit muscles 16 of the peripheral trunk 12.

  Here, in FIGS. 3 and 4, reference numeral 14 a is a thin slit portion that is thinner or cut than the other portions of the upper surface portion 11, and 14 c is different from the other portions of the upper surface portion 11. Thus, it is a thick cut portion that is thin and thicker than the thin cut portion 14a. 14b is a connection part formed between the thin tear part 14a and the thick tear part 14c, and is formed so that the thickness continuously changes from the thin tear part 14a to the thick tear part 14c. .

  The reason why the shape of the slit muscle 14 is made to be a pen point is that the height difference between the two sides of the tear muscle 14 does not occur as much as possible even if the rubber plug expands and deforms during sterilization, that is, a disk. This is because the slit 14 is formed so as not to follow the concentric circle centering on the center of the upper surface portion 11. This is because the split muscles 14 are formed near the center (near the through-hole 13) where the height difference between the two sides of the slit muscles 14 is relatively small compared to the other parts even if they are along concentric circles. Further, the tearing muscle 14 in the vicinity of the through-hole 13 where the tearing muscle 14 approaches the concentric shape is increased in thickness (thick tearing portion 14c) as compared with the other portion (thinning tearing portion 14a) of the tearing muscle 14. ), Its strength is increased.

  According to the first embodiment configured as described above, even when the rubber plug 3 expands and deforms in the process of sterilization performed under high pressure and high temperature, the slit muscle 14 is not cut throughout. Therefore, in this sterilization process, the portion surrounded by the cut muscle 14 is not lifted.

  Furthermore, in this embodiment, since the connection portion 14b is provided between the thin tear portion 14a and the thick tear portion 14c, when the user removes the base 10 and uses the chemical solution 2, If the lid member 20 is removed, the upper surface portion 11 of the base 10 can be smoothly cut along the tear line 14.
