Description

The present invention relates to a container for supplying a content liquid such as a drug to a coating tool.

Conventionally, there is a type of chemical solution in which a chemical solution contained in a container is impregnated into an application tool such as a cotton swab, and the cotton swab soaked with the chemical solution is applied to the affected area to apply the chemical solution to the affected area.

As a container for such a type of chemical solution, Japanese Patent Application Laid-Open No. 2598511 (Patent Document 1) discloses a chemical solution storage container provided with a container body, a pump device equipped with a push-down head, and a cotton swab insertion recess. doing. When the push-down head of the pump device is pushed down in this chemical liquid storage container, the chemical liquid stored in the container body is discharged into the cotton swab insertion recess. At that time, if the tip of the cotton swab is inserted into the cotton swab insertion recess, the tip of the cotton swab can be impregnated with the chemical solution.

Jitsuto 2598511 Gazette

However, in the conventional chemical solution storage container, the amount of the chemical solution supplied to the cotton swab is not stable because the cotton swab is impregnated with the chemical solution while being discharged by the pump device. That is, in the conventional chemical liquid storage container, the amount of the chemical liquid discharged changes depending on the amount of force for pushing down the push-down head. Therefore, the conventional chemical solution storage container has a problem that the amount of the chemical solution applied to the affected area or the like is different each time the chemical solution is applied.

Therefore, an object of the present invention is to provide a container capable of supplying a substantially constant amount of a content solution such as a chemical solution to a coating tool such as a cotton swab.

In order to solve the above problems, the present invention has taken the following technical measures. That is, the container according to the present invention may include a bottle having a mouth portion and a cap attached to the mouth portion of the bottle. The cap is a top plate having a coating tool insertion hole, a bottomed tubular measuring cup provided at the back of the coating tool insertion hole and opening toward the coating tool insertion hole, and a lid for sealing the coating tool insertion hole. May be equipped with. Between the measuring cup and the top plate, when the bottle is turned upside down with the coating tool insertion hole sealed by the lid, the contents flow toward the top plate through the flow path on the outer peripheral surface side of the measuring cup. An inflow opening may be formed to allow the liquid to flow into the inner peripheral surface side of the measuring cup. The measuring cup may be configured to accept the tip of the coating tool inserted through the coating tool insertion hole so that the content liquid accumulated in the measuring cup soaks into the coating tool.

With such a configuration, the container can impregnate the coating tool with a substantially constant amount of the content liquid. That is, when the bottle is turned upside down with the coating tool insertion hole sealed by the lid, the content liquid contained in the bottle flows into the measuring cup from the flow path on the outer peripheral surface side of the measuring cup via the inflow opening. To do. When the top and bottom of the bottle that has been turned upside down are returned to its original position, an almost constant amount of the content liquid accumulates in the measuring cup. By opening the lid that sealed the applicator insertion hole and inserting the tip of the applicator into the measuring cup through the applicator insertion hole, a substantially constant amount of the content liquid can be impregnated into the applicator. ..

Preferably, the lid may include a guide that is inserted through the applicator insertion hole and extends toward the measuring cup. The guide portion may have a guide groove for guiding the flow of the content liquid flowing from the inflow opening to the inner peripheral surface side of the measuring cup toward the inner bottom surface side of the measuring cup. As a result, the content liquid can be guided to flow toward the inner bottom surface side of the measuring cup along the guide groove of the guide portion. Therefore, the content liquid can flow more smoothly to the inner bottom surface side of the measuring cup, and the air in the measuring cup can be positively pushed away by the force of the flow of the content liquid, so that a stable and substantially constant amount can be obtained. The content liquid can be stored in a measuring cup.

Preferably, the same number of guide grooves as the inflow opening may be arranged facing each inflow opening. As a result, the content liquid can be more smoothly guided to the inner bottom surface side of the measuring cup from each inflow opening regardless of the direction in which the container is turned upside down.

Preferably, the outer peripheral surface of the measuring cup may be roughened to reduce the liquid flow resistance as compared with the smooth surface. As a result, the flow velocity of the content liquid is less likely to decrease on the outer peripheral surface of the measuring cup, and the flow path on the outer peripheral surface side of the measuring cup flows smoothly toward the top plate. Therefore, the content liquid can be flowed more smoothly toward the inner peripheral surface side of the measuring cup, and a substantially constant amount of the content liquid can be more stably stored in the measuring cup. The rough surface processing for reducing the liquid flow resistance may be, for example, a texture processing in which a fine uneven pattern applied to the surface of the mold when molding the cap is transferred to the surface of the measuring cup.

Preferably, at least one convex portion or concave portion may be provided in the circumferential middle portion of the opening end edge of the measuring cup that forms a part of the peripheral end of the inflow opening. As a result, the convex or concave portion breaks the surface tension of the content liquid that acts to stay at the opening edge of the measuring cup at the inflow opening, making it easier for the content liquid to flow into the inner peripheral surface side of the measuring cup. it can. Therefore, the content liquid can be flowed more smoothly toward the inner peripheral surface side of the measuring cup, and a substantially constant amount of the content liquid can be more stably stored in the measuring cup.

Preferably, the measuring cup is supported by the top plate via a plurality of support ribs that are separated from each other in the circumferential direction, and an inflow opening may be provided between the adjacent support ribs. As a result, the measuring cup can be supported on the top plate via the support ribs, and the content liquid can flow from the inflow opening to the inner peripheral surface side of the measuring cup regardless of the direction in which the container is turned upside down. Can be done.

According to the container according to the present invention, a substantially constant amount of the content liquid can be supplied to the coating tool.

[Embodiment]
Hereinafter, the container according to this embodiment will be specifically described with reference to FIGS. 1 to 10. As shown in FIGS. 1 and 2, the container 1 includes a bottle 2 and a cap 3.

The bottle 2 is formed in a bottomed tubular shape, and as shown in FIG. 2, has a mouth portion 21 that opens upward in the drawing. The bottle 2 is molded from a resin material such as PET or PE. The content liquid L is contained in the bottle 2. The content solution L is, for example, a chemical solution having a medicinal effect such as anti-itching, and is applied to an affected area or the like by impregnating it with an application tool such as a cotton swab. As the content liquid L, a liquid having a relatively high viscosity can be used, or a liquid having a relatively low viscosity similar to that of water can be used. As an example of the content solution L, a chemical solution having a kinematic viscosity at 25 ° C. of 2.0 to 5.0 mm ² / s can be used. The procedure for impregnating the coating tool with the content liquid L will be described later.

The cap 3 is attached to the mouth portion 21 on the side of the bottle 2 (lower side in the drawing). The cap 3 is made of a resin material such as PP. The cap 3 includes a cap body 3A and a lid 3B. The cap body 3A includes a cylindrical tubular portion 31, a top plate 32 that covers an opening on the discharge side (upper side in the drawing) of the content liquid L of the tubular portion 31, and a measuring cup 33 arranged inside the tubular portion 31. The top plate 32 is provided with a plurality of support ribs 34 for supporting the measuring cup 33. The lid 3B includes a lid main body 35 and a guide portion 36. The lid 3B is openably and closably connected to the top plate 32 via a hinge 37, covers the top plate 32 in a closed state, and seals the coating tool insertion hole 32a. The lid 3B may be made independent of the top plate 32 without a connecting tool such as a hinge 37, and may be detachably attached to the top plate 32.

The top plate 32 has a coating tool insertion hole 32a for inserting the tip end portion of the coating tool into the inner portion. The top plate 32 has a top plate side sealing portion 32b that projects annularly from the peripheral end of the coating tool insertion hole 32a.

The measuring cup 33 is formed in a bottomed tubular shape and opens toward the coating tool insertion hole 32a. The measuring cup 33 is configured to be able to accept the tip of the coating tool inserted through the coating tool insertion hole 32a so that the content liquid L accumulated in the measuring cup 33 soaks into the coating tool. The measuring cup 33 is supported by the top plate 32 via a plurality of support ribs 34 that are separated from each other in the circumferential direction. An inflow opening 38 is provided between the top plate 32 and the measuring cup 33 between the adjacent support ribs 34, respectively. The inflow opening 38 is a content liquid that flows toward the top plate 32 through the flow path on the outer peripheral surface side of the measuring cup 33 when the bottle 2 is turned upside down with the coating tool insertion hole 32a sealed by the lid 3B. L is allowed to flow into the inner peripheral surface side of the measuring cup 33. In the present embodiment, the support ribs 34 are provided with five support ribs 34 at equal intervals in the circumferential direction. Details of the plurality of support ribs 34 and the inflow opening 38 will be described later.

As shown in FIG. 3, the measuring cup 33 has a convex portion 33a at the middle portion in the circumferential direction of the opening end edge of the measuring cup 33 which constitutes a part of the peripheral end of the inflow opening 38. The convex portion 33a destroys the surface tension of the content liquid L that tends to stay at the peripheral end of the opening of the measuring cup 33 when the content liquid L tries to pass through the inflow opening 38. As a result, the content liquid L can flow more smoothly into the inner peripheral surface side of the measuring cup 33 through the inflow opening 38. From the viewpoint of destroying the surface tension of the content liquid L, the convex portion 33a may be a concave portion in which the central portion in the circumferential direction of the opening edge of the measuring cup 33 is depressed, although not particularly shown. Further, as shown in FIG. 4, the convex portion 33a may be raised linearly so as to extend radially from the outer peripheral bottom surface portion of the measuring cup 33. In the present embodiment, the convex portion 33a is formed on the outer peripheral surface side of the opening edge edge of the measuring cup 33, but may be formed on the upper surface side of the opening edge edge of the measuring cup 33. Further, at least one convex portion 33a of each inflow opening 38 may be provided.

The outer peripheral surface of the measuring cup 33 shown in FIG. 4 is roughened to form a fine concavo-convex structure. As a result, the liquid flow resistance of the outer peripheral surface of the measuring cup 33 can be reduced as compared with the smooth surface. The rough surface processing is, for example, grain processing, which is performed at the same time as the molding of the cap 3 by injection molding. The surface roughness of the outer peripheral surface of the measuring cup 33 subjected to the rough surface processing was measured in accordance with JISB0632: 2001, and the surface roughness (Rz) (defined in) was 0.01 to 0.2 μm. Is. The lower limit of Rz is 0.01 μm, preferably 0.03 μm, more preferably 0.028 μm, and the upper limit is 0.2 μm, preferably 0.18 μm, more preferably 0.177 μm. Is. If the uneven structure can be formed on the outer peripheral surface of the measuring cup 33, the rough surface processing may be performed by, for example, plasma treatment, etching treatment, sandblasting, or polishing treatment.

By reducing the liquid flow resistance on the outer peripheral surface of the measuring cup 33 in this way, the fluidity of the content liquid L on the outer peripheral surface side of the measuring cup 33 can be improved. As a result, it is possible to suppress a decrease in the flow velocity of the content liquid L in the flow path on the outer peripheral surface side of the measuring cup 33, and the content liquid L can flow smoothly toward the top plate 32, and is more stable and substantially constant. A large amount of the content liquid L can be stored in the measuring cup 33.

The rough surface processing for reducing the liquid flow resistance is, for example, a water-repellent processing or a hydrophilic processing. Whether the liquid flow resistance is reduced by the water-repellent treatment or the hydrophilic treatment is considered to be determined depending on the material of the outer peripheral surface of the measuring cup 33, the shape of the uneven structure, the type of the content liquid L, and the like (Review of Policy, Vol 54, No. 2, (2008) "Effect of Surface Roughness on Wetting on Solid Surface"). Therefore, whether to select the water-repellent treatment or the hydrophilic treatment may be appropriately determined according to the material of the outer peripheral surface of the measuring cup 33 and the like. When the peripheral edge of the inflow opening 38 is roughened, the surface tension of the content liquid L that tends to accumulate on the front side of the inflow opening 38 when the content liquid L tries to pass through the inflow opening 38 is increased. It can also be expected to have the effect of breaking and allowing the content liquid L to flow more smoothly into the inner peripheral surface side of the measuring cup 33 through the inflow opening 38.

Further, the upper surface of the open end of the measuring cup 33 may be a smooth surface without roughening to reduce the liquid flow resistance. For example, when the liquid flow resistance is reduced by hydrophilic processing, the outer peripheral surface of the measuring cup 33 is subjected to hydrophilic processing and the upper surface of the opening edge is not subjected to hydrophilic processing, so that the upper surface of the opening end of the measuring cup 33 is not subjected to hydrophilic processing. Even if the surplus content liquid L is attached to the measuring cup 33, the surplus content liquid L can be guided to the outer peripheral surface side of the measuring cup 33, and the measuring accuracy is improved. On the other hand, when the liquid flow resistance is reduced by the water-repellent treatment, the outer peripheral surface of the measuring cup 33 is water-repellent and the upper surface of the opening end is not water-repellent, so that the measuring cup is opened from the inflow opening 38. The content liquid L easily flows into the inner peripheral surface side of 33.

The lid 3B includes a disk-shaped lid body 35 that covers the top plate 32, and a guide portion 36 that is inserted from the coating tool insertion hole 32a with the lid body 35 closed and extends toward the measuring cup 33. There is. The guide portion 36 has a guide groove 36a. The guide groove 36a guides the flow of the content liquid L flowing from the inflow opening 38 to the inner peripheral surface side of the measuring cup 33 toward the inner bottom surface side of the measuring cup 33 (see arrow X in FIG. 6). As shown in FIG. 3, the partition formed between the guide grooves 36a is formed so as to face the plurality of support ribs 34 with the lid 35 closed. Therefore, the same number of guide grooves 36a are formed as the inflow openings 38, and the guide grooves 36a are arranged so as to face each inflow opening 38.

By providing the guide portion 36 having the guide groove 36a in this way, the content liquid L is guided from each inflow opening 38 to the inner bottom surface side of the measuring cup 33 by each guide groove 36a, and the air in the measuring cup 33 is introduced. Since the content liquid L can be positively pushed away by the force of the flow, the content liquid L can be more smoothly stored in the measuring cup 33. As a result, a substantially constant amount of the content liquid L can be more stably stored in the measuring cup 33.

Further, the lid 3B has a lid-side sealing portion 39 protruding in an annular shape around the guide portion 36. As shown in FIG. 5, the outer surface of the lid-side seal portion 39 abuts on the inner surface of the top plate-side seal portion 32b with the lid 3B closed, and seals the content liquid L so as not to leak.

As described above, according to the container according to the present invention, the content liquid L contained in the bottle 2 can be smoothly flowed to the inner peripheral surface side of the measuring cup 33, and a substantially constant amount is contained in the measuring cup 33. The content liquid L can be stably stored. As a result, a substantially constant amount of the content liquid L can be supplied to the coating tool inserted into the measuring cup 33 from the coating tool insertion hole 32a.

(Modification example)
In the above-described embodiment, five support ribs 34 are provided to form five inflow openings 38, but 2 to 7 support ribs 34 may be provided to form 2 to 7 inflow openings 38, respectively. In that case, the number of guide grooves 36a of the lid 35 may be the same as the number of inflow openings 38.

In the above-described embodiment, in the flow path on the outer peripheral surface side of the measuring cup 33, in order to improve the flow of the content liquid L, the outer peripheral surface of the measuring cup 33 is roughened to reduce the liquid flow resistance. The inner peripheral surface of the mouth portion 21 that faces the outer peripheral surface of the measuring cup 33 in the radial direction may be roughened to reduce the liquid flow resistance, and the outer surface of the convex portion 33a and the support rib 34 may be subjected to the liquid flow resistance. Roughing may be performed to reduce the amount of

Although the embodiments have been described above, the present invention is not limited to the above embodiments, and various modifications can be made as long as the gist of the present invention is not deviated.

[how to use]
Next, the method of using the container 1 will be specifically described with reference to FIGS. 5 to 8.

First, as shown in FIG. 5, the user prepares a container 1 in which the content liquid L is contained in the bottle 2 and the lid 3B is closed.

Next, as shown in FIG. 6, the user flips the bottle 2 upside down. Then, as shown by the arrow X in the figure, the content liquid L contained in the bottle 2 flows out toward the top plate 32, passes through the flow path on the outer peripheral surface side of the measuring cup 33, and passes through the inflow opening 38 to the measuring cup. It flows into the inner peripheral surface side of 33. At this time, as described above, the outer peripheral surface of the measuring cup 33 is roughened to reduce the liquid flow resistance, and the convex portion 33a is provided at the opening edge of the measuring cup 33. Since the guide groove 36a for guiding the content liquid L to the inner peripheral surface side of the measuring cup 33 is provided, the content liquid L smoothly flows into the inner peripheral surface side of the measuring cup 33.

Next, as shown in FIG. 7, when the top and bottom of the bottle 2 are returned to their original positions, the content liquid L collects on the inner peripheral surface side of the measuring cup 33. Further, the content liquid L overflowing from the measuring cup 33 flows to the bottom surface side of the bottle 2 and is housed in the bottle 2. In this way, the content liquid L is stored in the entire measuring cup 34. As a result, the container 1 can stably store a substantially constant amount of the content liquid L in the measuring cup 33 for each measurement.

Finally, as shown in FIG. 8, the lid 3B is opened to open the coating tool insertion hole 32a, and the tip portion of the coating tool C is inserted through the coating tool insertion hole 32a. The measuring cup 33 is formed so that the tip portion of the coating tool C can be received, for example, the shape of the inner bottom surface side of the measuring cup 33 corresponds to the shape of the outer surface of the tip portion of the coating tool C. The content liquid L accumulated in the measuring cup 33 soaks into the coating tool C. In this way, a substantially constant amount of the content liquid L can be impregnated into the coating tool C.

The user applies the content liquid L by applying the coating tool C soaked with the content liquid L to the affected area or the like. As a result, the user can apply a substantially constant amount of the content liquid L to the affected area or the like.

[Example]
Next, regarding the quality of the ease with which the content liquid L flows into the measuring cup 33, the containers 1 according to Examples 1 to 4 were prepared and tested as follows. The container 1 according to the first to third embodiments has the same basic configuration as the container 1 of the above-described embodiment. Therefore, only the structural difference between each container 1 of Examples 1 to 3 and the container 1 of the above-described embodiment will be described below. The container 1 of the fourth embodiment is the same as the container 1 according to the above-described embodiment.

(Test 1)
[Example 1]
As shown in FIG. 9A, the container 1 of the first embodiment is composed of three support ribs 34 that support the measuring cup 33. The three support ribs 34 are configured to be spaced apart at equal intervals in the circumferential direction. Three inflow openings 37 are provided between the three support ribs 34. Further, in the above-described embodiment, the convex portion 33a is provided in the middle of the opening edge of the measuring cup 33 in the circumferential direction in each inflow opening 38, but the container 1 of the first embodiment is provided with the convex portion 33a. Absent.

[Example 2]
As shown in FIG. 9B, the container 1 of the second embodiment is composed of four support ribs 34 that support the measuring cup 33. The four support ribs 34 are configured to be spaced apart at equal intervals in the circumferential direction. Four inflow openings 38 are provided between the four support ribs 34. Further, also in the container 1 of the second embodiment, the convex portion 33a is not provided.

[Example 3]
As shown in FIG. 9C, the container 1 of the third embodiment is configured with five support ribs 34 as in the above-described embodiment. Five inflow openings 38 are provided between the five support ribs. Further, also in the container 1 of the second embodiment, the convex portion 33a is not provided.

[Example 4]
As shown in FIG. 9D, the container 1 of the fourth embodiment is provided with five support ribs 34 and five inflow openings 38, as in the above-described embodiment, and each inflow opening 38 is provided with five support ribs 34. Convex portions 33a are provided at the opening edges of the measuring cup 33, respectively.

In the container 1 of Examples 1 to 4, the container 1 is tilted in each direction of the arrows Y1, Y2, and Y3 in each drawing to reverse the container 1 and the content liquid L flowing to the inner peripheral surface side of the measuring cup 33. The ease of flow was evaluated on a three-point scale of "good," "possible," and "poor."

As shown in FIG. 10, in the container 1 of the first embodiment, when the container 1 was tilted in the direction of Y1 and turned upside down, the content liquid L flowed well toward the inner peripheral surface side of the measuring cup 33 (“good”). ). However, when the container 1 is tilted in the direction of Y2 and Y3 and the container 1 is turned upside down, the content liquid L does not flow well toward the inner peripheral surface side of the measuring cup 33, and the content liquid L accumulated in the measuring cup 33 is small. ("Bad").

In the container 1 of the second embodiment, when the container 1 was tilted in the direction of Y2 and turned upside down, it was “good”. However, when the container 1 was tilted in the directions of Y1 and Y3 and the container 1 was turned upside down, it was "defective".

As described above, in the containers 1 of Examples 1 and 2, by tilting the container 1 in a predetermined direction and turning it upside down, a substantially constant amount of the content liquid L could be stored in the measuring cup 33.

In the container 1 of Example 3, when the container 1 was tilted in the directions of Y1, Y2, and Y3 and turned upside down, it was "OK" in any of the directions.

As described above, in the container 1 of the third embodiment, the flow of the content liquid L cannot be said to be “good”, and the amount of the content liquid L that can be stored in the measuring cup 33 is small, but in any direction. Also, a substantially constant amount of the content liquid L could be stored in the measuring cup 33.

In the container 1 of Example 4, when the container 1 was tilted in the directions of Y1, Y2, and Y3 and turned upside down, it was "good" in any of the directions.

As described above, in the container 1 of the fourth embodiment, regardless of the direction in which the container 1 is tilted and turned upside down, the flow of the content liquid L is improved regardless of the direction in which the container 1 is turned upside down. Moreover, a substantially constant amount of the content liquid L could be stably stored in the measuring cup 33. Therefore, it is considered that the flow of the content liquid L can be optimized by setting the number of the support ribs 34 to 5 and providing the convex portion 33a in the container 1.

Although not particularly shown, the flow of the content liquid L was evaluated by increasing the size of the measuring cup 33 under the same conditions as in Example 4. As a result, as in Example 4, it was "good" in all directions. Therefore, even if the size of the measuring cup changes, from the viewpoint of improving the flow of the content liquid L and storing a substantially constant amount of the content liquid L in the measuring cup 33, the number of support ribs 34 is set to five. It is considered preferable to provide the convex portion 33a in the inflow opening 38.

(Test 2)
Next, a wettability test was conducted using a test piece 1 made of PET resin and a test piece 2 made of PP resin. The PET resin of the test piece 1 is a molding material for the bottle 2, and the PP resin of the test piece 2 is a molding material for the cap 3. Each of the test piece 1 and the test piece 2 has a rectangular smooth surface. The rectangular smooth surface has a width of 40 mm and a length of 55 mm. For the wettability test, a portable contact angle meter PCA-11 manufactured by Kyowa Interface Science Co., Ltd. was used, and 2 μl of a 70 wt% propylene aqueous solution (2 μl) as a standard solution was applied to each of the smooth surface of the test piece 1 and the smooth surface of the test piece 2. The content liquid L) was added dropwise, and the contact angle after 3 seconds was determined.

The surface tension of the standard solution was measured at 20 ° C. using a portable contact angle meter PCA-11 (manufactured by Kyowa Interface Science Co., Ltd.) and was 33.9 mN / m. The density of the standard solution required for measuring the surface tension of the standard solution was measured at 20 ° C. using a density hydrometer DA-650 (manufactured by Kyoto Denshi Kogyo Co., Ltd.). The viscosity of the standard solution was measured at 20 ° C. using a rotary viscometer TVE-35H (manufactured by Toki Sangyo Co., Ltd.) and was 22.7 mPa · s.

The contact angle is indicated by 0 to 180 degrees, and the wettability becomes better as the contact angle becomes smaller and worse as the contact angle becomes larger. As a result of the test, the contact angle of the test piece 1 was 39.6 degrees, and the contact angle of the test piece 2 was 54.9 degrees. As described above, it was found that the test piece 1 and the test piece 2 each have a relatively small contact angle and have good wettability even on a smooth surface. That is, when the liquid flow resistance is reduced by hydrophilic processing, the wettability can be further improved by performing hydrophilic processing such as embossing on each of the smooth surface of the test piece 1 and the smooth surface of the test piece 2. , It is considered that the liquid flow resistance can be further reduced.
