Description

Container with a lid

Technical Field

The present invention relates to a container for supplying a content liquid such as a medicine to a smearing tool.

Background

In the past, there are the following types of chemical solutions: the liquid medicine contained in the container is made to permeate into the smearing tool such as a cotton swab, and the cotton swab permeated with the liquid medicine is made to contact with the affected part to smear the liquid medicine on the affected part.

As a container for such a type of liquid medicine, japanese utility model registration No. 2598511 (patent document 1) discloses a liquid medicine storage container including a container main body, a pump device equipped with a pressing head, and a cotton bud insertion recess. In this chemical liquid container, when the pressing head of the pump device is pressed, the chemical liquid contained in the container body is discharged to the swab insertion recess. In this case, when the tip portion of the cotton bud is inserted into the cotton bud insertion recess in advance, the chemical solution can penetrate into the tip portion of the cotton bud.

However, in the conventional chemical liquid container, since the chemical liquid is allowed to permeate into the cotton swab while the chemical liquid is discharged by the pump device, the amount of the chemical liquid supplied to the cotton swab is unstable. That is, in the conventional chemical liquid container, the amount of the chemical liquid discharged varies due to an increase or decrease in the force with which the pressing head is pressed. Therefore, the conventional chemical solution storage container has the following problems: the amount of the liquid medicine applied to the affected part or the like varies every time the liquid medicine is applied.

Disclosure of Invention

Accordingly, an object of the present invention is to provide a container capable of supplying a substantially constant amount of content liquid such as a chemical liquid to an applicator such as a swab.

In order to solve the above problems, the present invention adopts the following technical means. That is, the container of the present invention may include: a body having a mouth; and a cap attached to the mouth of the body. The bottle cap may include: a top plate having a smear tool insertion hole; a bottomed cylindrical measuring cup which is provided inside the applicator insertion hole and opens toward the applicator insertion hole; and a cover sealing the smear tool insertion hole. An inflow opening may be formed between the measuring cup and the top plate, and the inflow opening may allow the content liquid flowing toward the top plate through the flow path on the outer circumferential surface side of the measuring cup to flow into the inner circumferential surface side of the measuring cup when the body is turned upside down in a state where the applicator insertion hole is sealed by the cap. The measuring cup may be configured to receive a tip end portion of the applicator inserted from the applicator insertion hole so that the content liquid stored in the measuring cup penetrates into the applicator.

According to this structure, the container can allow a substantially constant amount of the content liquid to permeate into the application tool. That is, when the body is turned upside down with the applicator insertion hole sealed by the cap, the content liquid contained in the body flows into the measuring cup from the flow path on the outer peripheral surface side of the measuring cup through the inflow opening. When the body turned upside down is restored from the upper and lower positions, a substantially constant amount of the content liquid is stored in the measuring cup. The applicator can be inserted into the measuring cup from the applicator insertion hole by opening the cover for closing the applicator insertion hole, thereby allowing a substantially constant amount of the content liquid to penetrate into the applicator.

Preferably, the cover may be provided with a guide portion inserted from the plastering tool insertion hole and extending toward the measuring cup. The guide portion may have a guide groove that guides the flow of the content liquid flowing into the inner peripheral surface side of the measuring cup from the inflow opening toward the inner bottom surface side of the measuring cup. This allows the content liquid to be guided so as to flow toward the inner bottom surface of the measuring cup along the guide groove of the guide portion. Therefore, the content liquid can be made to flow more smoothly toward the inner bottom surface side of the measuring cup, and the air in the measuring cup can be positively pushed out by the flow force of the content liquid, so that a substantially constant amount of the content liquid can be stably stored in the measuring cup.

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

Preferably, the outer peripheral surface of the measuring cup may be subjected to a rough surface treatment for reducing liquid flow resistance as compared with a smooth surface. Thus, 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 smoothly flows toward the top plate. Therefore, the content liquid can be made to flow more smoothly toward the inner peripheral surface side of the measuring cup, and a substantially constant amount of the content liquid can be stored in the measuring cup more stably. The rough surface processing for reducing the liquid flow resistance may be, for example, a cockling processing for transferring a fine uneven pattern applied to the mold surface at the time of forming the bottle cap to the measuring cup surface.

Preferably, at least one convex portion or concave portion may be provided at a circumferential middle portion of an opening end edge of the measuring cup constituting a part of a circumferential end of the inflow opening. Thus, the convex portion or the concave portion breaks the surface tension of the content liquid that is intended to remain at the opening edge of the measuring cup at the inflow opening, and the content liquid can be easily caused to flow into the inner peripheral surface side of the measuring cup. Therefore, the content liquid can be made to flow more smoothly toward the inner peripheral surface side of the measuring cup, and a substantially constant amount of the content liquid can be stored in the measuring cup more stably.

Preferably, the measuring cup may be supported by the top plate via a plurality of support ribs spaced apart in the circumferential direction, and the inflow openings are provided between the adjacent support ribs, respectively. Thus, the measuring cup can be supported by the top plate via the support rib, and the content liquid can be made to flow into the inner peripheral surface side of the measuring cup from the inflow opening regardless of the direction in which the container is turned upside down.

Effects of the invention

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

Detailed Description

[ embodiment ]

The container of the present embodiment will be specifically described below with reference to fig. 1 to 10. As shown in fig. 1 and 2, the container 1 includes a body 2 and a cap 3.

The bottle body 2 is formed in a bottomed cylindrical shape and has a mouth portion 21 opened upward in the figure as shown in fig. 2. The body 2 is formed by molding a resin material such as PET or PE. The bottle body 2 contains a content liquid L. The content liquid L is, for example, a toolMedicinal liquid with antipruritic effect can be applied to affected part by permeating into applicator such as cotton stick. As the content liquid L, a content liquid having a high viscosity can be used, and a content liquid having a low viscosity can be used to the same extent as water. As an example of the content liquid L, a liquid having a kinematic viscosity at 25 ℃ of 2.0 to 5.0mm can be used²(ii) liquid medicine per second. The procedure of impregnating the content liquid L into the applicator will be described later.

The cap 3 is attached to a mouth portion 21 on the body 2 side (lower side in the figure). The bottle cap 3 is made of a resin material such as PP. The cap 3 includes a cap body 3A and a cap 3B. The cap body 3A includes a cylindrical tube 31, a top plate 32 covering an opening on the discharge side (upper side in the drawing) of the content liquid L of the tube 31, a measuring cup 33 disposed inside the tube 31, and a plurality of support ribs 34 for supporting the measuring cup 33 on the top plate 32. The cover 3B includes a cover body 35 and a guide portion 36. The cover 3B is coupled to the top plate 32 via a hinge 37 so as to be openable and closable with respect to the top plate 32, covers the top plate 32 in a closed state, and seals the applicator insertion hole 32a. The cover 3B may be configured to be independent from the top plate 32 without using a coupling tool such as a hinge 37, and to be detachable from the top plate 32.

The top plate 32 has an applicator insertion hole 32a for inserting the front end portion of the applicator into the inside thereof. The top plate 32 has a top plate side seal portion 32b annularly protruding from the peripheral end of the smear tool insertion hole 32a.

The measuring cup 33 is formed in a bottomed cylindrical shape and opens toward the applicator insertion hole 32a. The measuring cup 33 is configured to receive the tip end portion of the applicator inserted from the applicator insertion hole 32a so that the content liquid L stored in the measuring cup 33 can permeate into the applicator. The measuring cup 33 is supported on the top plate 32 via a plurality of support ribs 34 spaced apart in the circumferential direction. Between the top plate 32 and the measuring cup 33, an inflow opening 38 is provided between the adjacent support ribs 34. When the body 2 is turned upside down with the applicator insertion hole 32a sealed by the cap 3B, the inflow opening 38 causes the content liquid L flowing toward the top plate 32 through the flow passage on the outer peripheral surface side of the measuring cup 33 to flow into the inner peripheral surface side of the measuring cup 33. In the present embodiment, 5 support ribs 34 are provided at equal intervals in the circumferential direction with respect to the support ribs 34. 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 a circumferential middle portion of an opening end edge of the measuring cup 33 constituting a part of a circumferential end of the inflow opening 38. The convex portion 33a breaks the surface tension of the content liquid L remaining at the opening peripheral end of the measuring cup 33 when the content liquid L passes through the inflow opening 38. This enables the content liquid L to flow more smoothly into the inner peripheral surface of the measuring cup 33 through the inflow opening 38. The convex portion 33a may be a concave portion that is recessed in a circumferential middle portion of the opening edge of the measuring cup 33, although not particularly shown, from the viewpoint of breaking the surface tension of the content liquid L. As shown in fig. 4, the convex portion 33a may be linearly raised so as to extend radially from the outer bottom surface 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 of the measuring cup 33, but may be formed on the upper surface side of the opening edge of the measuring cup 33. Further, at least one of the convex portions 33a of the inflow openings 38 may be provided.

The outer peripheral surface of the measuring cup 33 shown in fig. 4 is subjected to rough surface processing for forming a fine uneven structure. This can reduce the liquid flow resistance on the outer peripheral surface of the measuring cup 33 as compared with a smooth surface. The rough surface processing is, for example, a crimping processing, and is performed simultaneously with the formation of the bottle cap 3 by injection molding. Regarding the surface roughness of the outer peripheral surface of the measuring cup 33 subjected to the rough surface processing, the surface roughness is determined by JISB 0632: 2001 measured (defined) surface roughness (Rz) of 0.01 to 0.2 μm. The lower limit of Rz is 0.01. mu.m, preferably 0.03. mu.m, more preferably 0.028. mu.m, and the upper limit is 0.2. mu.m, preferably 0.18. mu.m, more preferably 0.177. mu.m. The rough surface processing may be performed by, for example, plasma treatment, etching treatment, sandblasting, polishing treatment, or the like, as long as the concave-convex structure can be formed on the outer peripheral surface of the measuring cup 33.

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, 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 can be suppressed, the content liquid L can be made to flow smoothly toward the top plate 32, and a substantially constant amount of the content liquid L can be stored in the measuring cup 33 more stably.

The rough surface processing that reduces the liquid flow resistance is, for example, hydrophobic processing or hydrophilic processing. Whether the liquid flow resistance is reduced by hydrophobic processing or hydrophilic processing may 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 (see Review of polarization, Vol54, No.2, (2008) "effect of wettability of surface roughness to solid surface"). Therefore, whether to select the hydrophobic processing or the hydrophilic processing can be appropriately determined according to the material of the outer peripheral surface of the measuring cup 33. When the peripheral edge of the inlet opening 38 is roughened, the following effects can be expected: when the content liquid L is about to pass through the inflow opening 38, the surface tension of the content liquid L which is about to accumulate in the vicinity of the inflow opening 38 is broken, and the content liquid L can be more smoothly flowed into the inner peripheral surface side of the measuring cup 33 through the inflow opening 38.

The upper surface of the open end of the measuring cup 33 may be formed to be a smooth surface without performing rough surface processing for reducing liquid flow resistance. For example, in the case where the liquid flow resistance is reduced by hydrophilic processing, the outer peripheral surface of the measuring cup 33 is subjected to hydrophilic processing without subjecting the upper surface of the opening edge to hydrophilic processing, whereby even if the excess content liquid L adheres to the upper surface of the opening end of the measuring cup 33, the excess content liquid L can be guided to the outer peripheral surface side of the measuring cup 33, and the measuring accuracy can be improved. On the other hand, when the liquid flow resistance is reduced by the water-repellent treatment, the content liquid L is easily poured from the inflow opening 38 into the inner peripheral surface side of the measuring cup 33 by performing the water-repellent treatment on the outer peripheral surface of the measuring cup 33 without performing the water-repellent treatment on the upper surface of the opening end.

The cover 3B includes: a disk-shaped cover body 35 that covers the top plate 32; and a guide portion 36 inserted from the plastering tool insertion hole 32a in a state where the cover body 35 is closed and extending toward the measuring cup 33. 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 into the inner circumferential 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 partitioning members formed between the guide grooves 36a are formed so as to face the plurality of support ribs 34, respectively, in a state where the cover 35 is closed. Therefore, the guide grooves 36a are formed in the same number as the number of the inflow openings 38, and are arranged to face the inflow openings 38, respectively.

By providing the guide portion 36 having the guide grooves 36a in this manner, the content liquid L is guided from the inflow openings 38 to the inner bottom surface side of the measuring cup 33 by the guide grooves 36a, and air in the measuring cup 33 is actively pushed out by the flow force of the content liquid L, so that the content liquid L can be stored in the measuring cup 33 more smoothly. As a result, a substantially constant amount of the content liquid L can be stored in the measuring cup 33 more stably.

The cover 3B has a cover-side seal portion 39 that protrudes annularly around the guide portion 36. As shown in fig. 5, in a state where the lid 3B is closed, the outer surface of the lid-side sealing portion 39 abuts against the inner surface of the top-plate-side sealing portion 32B, and sealing is performed so that the content liquid L does not leak.

As described above, according to the container of the present invention, the content liquid L contained in the body 2 can smoothly flow toward the inner peripheral surface side of the measuring cup 33, and a substantially constant amount of the content liquid L can be stably stored in the measuring cup 33. This enables a substantially constant amount of the content liquid L to be supplied to the applicator inserted into the measuring cup 33 from the applicator insertion hole 32a.

(modification example)

In the above embodiment, 5 support ribs 34 are provided to constitute 5 inflow openings 38, but 2 to 7 support ribs 34 may be provided to constitute 2 to 7 inflow openings 38, respectively. In this case, the number of the guide grooves 36a of the cover 35 may be the same as the number of the inflow openings 38.

In the above-described embodiment, in the flow path on the outer peripheral surface side of the measuring cup 33, the outer peripheral surface of the measuring cup 33 is subjected to the roughening process for reducing the liquid flow resistance in order to improve the flow of the content liquid L, but the inner peripheral surface of the mouth portion 21 facing the outer peripheral surface of the measuring cup 33 in the radial direction may be subjected to the roughening process for reducing the liquid flow resistance, or the outer surfaces of the convex portion 33a and the support rib 34 may be subjected to the roughening process for reducing the liquid flow resistance.

The embodiments have been described above, but the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the invention.

[ method of use ]

Next, a method of using the container 1 will be specifically described with reference to fig. 5 to 8.

First, as shown in fig. 5, the user prepares the container 1 in a state in which the content liquid L is stored in the body 2 and the lid 3B is closed.

Next, as shown in fig. 6, the user turns the body 2 upside down. Then, as shown by an arrow X in the figure, the content liquid L contained in the body 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 flows from the inflow opening 38 to the inner peripheral surface side of the measuring cup 33. At this time, as described above, the rough surface processing for reducing the liquid flow resistance is performed on the outer peripheral surface of the measuring cup 33, the convex portion 33a is provided at the opening edge end of the measuring cup 33, and the guide groove 36a for guiding the content liquid L to the inner peripheral surface side of the measuring cup 33 is provided, so that 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 body 2 is restored vertically, the content liquid L is accumulated on the inner peripheral surface side of the measuring cup 33. The content liquid L overflowing from the measuring cup 33 flows toward the bottom surface of the body 2 and is stored in the body 2. In this way, the content liquid L is stored in the entire measuring cup 34. This enables the container 1 to 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 cover 3B is opened to open the plastering tool insertion hole 32a, and the tip end portion of the plastering tool C is inserted from the plastering tool insertion hole 32a. The measuring cup 33 can receive the tip of the applicator C, and for example, the inner bottom surface of the measuring cup 33 is formed in a shape corresponding to the outer surface of the tip of the applicator C. The content liquid L stored in the measuring cup 33 penetrates into the applicator C. In this way, a substantially constant amount of the content liquid L can be infiltrated into the plastering tool C.

The user applies the content liquid L by contacting the applicator C into which the content liquid L has been infiltrated with the affected part or the like. This allows the user to apply a substantially constant amount of the content liquid L to the affected area or the like.

[ examples ]

Next, the containers 1 of examples 1 to 4 were prepared for the purpose of determining whether the ease with which the content liquid L flowed into the measuring cup 33 was good, and the following tests were performed. The basic structure of the container 1 of examples 1 to 3 is the same as that of the container 1 of the above embodiment. Therefore, only the differences in the structure between the containers 1 of examples 1 to 3 and the container 1 of the above embodiment will be described below. The container 1 of example 4 is the same as the container 1 of the above embodiment.

(test 1)

[ example 1]

As shown in fig. 9 (a), the container 1 of example 1 has 3 support ribs 34 for supporting the measuring cup 33. The 3 support ribs 34 are configured to be equally spaced apart in the circumferential direction. Between the 3

support ribs

34, 3 inflow openings 37 are provided. In the above embodiment, the convex portion 33a is provided in the middle of the opening edge of the measuring cup 33 in the circumferential direction at each inflow opening 38, but the convex portion 33a is not provided in the container 1 of example 1.

[ example 2]

As shown in fig. 9 (b), the container 1 of example 2 is provided with 4 supporting ribs 34 for supporting the measuring cups 33. The 4 support ribs 34 are configured to be equally spaced apart in the circumferential direction. Between the 4 support ribs 34, 4 inflow openings 38 are provided. In addition, the container 1 of example 2 is also not provided with the convex portion 33a.

[ example 3]

As shown in fig. 9 (c), the container 1 of example 3 has 5 support ribs 34 in the same manner as in the above-described embodiment. Between the 5 support ribs 5 inflow openings 38 are provided. In addition, the container 1 of example 3 is also not provided with the convex portion 33a.

[ example 4]

As shown in fig. 9 (d), the container 1 of example 4 is provided with 5

support ribs

34 and 5 inflow openings 38 as in the above-described embodiment, and further, a protrusion 33a is provided at each of the inflow openings 38 at the opening edge end of the measuring cup 33.

In the containers 1 of examples 1 to 4, the ease of flow of the content liquid L to the inner peripheral surface side of the measuring cup 33 was evaluated on 3 ranks "good", "ok", and "no", by tilting the container 1 in the directions of arrows Y1, Y2, and Y3 in the drawings to turn the container 1 upside down.

As shown in fig. 10, in the case where the container 1 of example 1 was tilted in the direction Y1 and turned upside down, the content liquid L flowed favorably toward the inner peripheral surface side of the measuring cup 33 ("good"). However, when the container 1 is tilted in the directions Y2 and Y3 and 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 (defective).

The container 1 of example 2 was "good" when the container 1 was tilted in the direction Y2 and turned upside down. However, if the container 1 is tilted in the Y1 and Y3 directions and turned upside down, it is "defective".

In this way, in the container 1 of examples 1 and 2, the content liquid L of a substantially constant amount can be stored in the measuring cup 33 by tilting the container 1 in a predetermined direction and turning it upside down.

In the case where the container 1 of example 3 is tilted in the directions Y1, Y2, and Y3 and turned upside down, the container 1 is "ok" in any direction.

As described above, in the container 1 of example 3, the flow of the content liquid L cannot be said to be "good", and although the amount of the content liquid L that can be accumulated in the measuring cup 33 is small, a substantially constant amount of the content liquid L can be accumulated in the measuring cup 33 in any direction.

In the case of the container 1 of example 4, the container 1 was tilted in the directions Y1, Y2, and Y3 and turned upside down, and was "good" in any direction.

As described above, in the container 1 of example 4, even when the container 1 is tilted in any direction and turned upside down, the flow of the content liquid L can be improved regardless of the direction in which the container 1 is turned upside down, and a substantially constant amount of the content liquid L can be stably stored in the measuring cup 33. Therefore, it is considered that the flow of the content liquid L can be optimized by providing the container 1 with the convex portions 33a while setting the number of the support ribs 34 to 5.

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, the film was "good" in any direction as in example 4. Therefore, even if the size of the measuring cup is changed, it is considered that it is preferable to provide 5 support ribs 34 and provide the convex portions 33a in the inflow openings 38, from the viewpoint of making the flow of the content liquid L good and accumulating a substantially constant amount of the content liquid L in the measuring cup 33.

(test 2)

Next, a wettability test was performed 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 was a molding material of the body 2, and the PP resin of the test piece 2 was a molding material of the cap 3. Each of the

test pieces

1 and 2 has a rectangular smooth surface. The rectangular smooth surface has a width of 40mm and a length of 55 mm. In the wettability test, using a portable contact angle meter PCA-11 (manufactured by Kyowa Kagaku Co., Ltd.), 2. mu.l of a 70 wt% propylene aqueous solution (content liquid L) was dropped as a standard solution onto each of the smooth surface of the test piece 1 and the smooth surface of the test piece 2, and the contact angle after 3 seconds was obtained.

The surface tension of the standard solution was measured at 20 ℃ with a portable contact angle meter PCA-11 (manufactured by Kyowa Kagaku K.K.) and found to be 33.9 mN/m. The density of the standard solution required for measuring the surface tension of the standard solution was measured at 20 ℃ using a densitometer DA-650 (manufactured by Kyoto electronics industries, Ltd.). The viscosity of the standard solution was measured at 20 ℃ using a rotary viscometer TVE-35H (manufactured by Toyobo industries Co., Ltd.) and found to be 22.7 mPas.

The contact angle is expressed by 0 to 180 degrees, and the wettability is better as the contact angle is smaller, and the wettability is worse as the contact angle is 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. Thus, it was found that the contact angles of the

test pieces

1 and 2 were small, and the wettability was good even on a smooth surface. That is, when the liquid flow resistance is reduced by hydrophilic processing, it is considered that the wettability can be further improved and the liquid flow resistance can be further reduced by subjecting the smooth surface of the test piece 1 and the smooth surface of the test piece 2 to hydrophilic processing such as drape processing, respectively.
