Patent Description:
There has been conventionally developed a type of medical solution applying container not only for storing a medical solution but also for applying the medical solution to human skin or so forth with a brush attached thereto (e.g., <CIT>).

<CIT> discloses an applicator comprising a solution container according to the preamble of claim <NUM> and which comprises an opening, and a columnar brush member formed by bundling synthetic fibers in a columnar shape. The columnar brush member is disposed at the opening of the solution container, a tip portion of the columnar brush member at an outside of the solution container has a fan shape expanding in a perpendicular lateral direction against a pillar axial lengthwise direction, and a thickness of the fan-shaped tip portion of the columnar brush member decreases in a perpendicular lengthwise direction against the pillar axial lengthwise direction toward the tip portion of the columnar brush member. The liquid applicator of the present invention has the fan-shaped tip portion so that irritation on an affected part may be decreased and a liquid tinea medicine may be applied to the affected part.

In general, such a medical solution applying container as described above includes a medical solution container body made of a material with plasticity and stores a medical solution therein. The medical solution container body is pinched or squeezed by a user when the medical solution is applied to the skin or so forth of the user. The amount of medical solution extracted from the medical solution applying container is configured to be adjusted in accordance with adjustment in level of pinching or squeezing by the user.

Specifically, when the medical solution container body is squeezed strongly, a large amount of medical solution is absorbed into the brush and is then extracted therefrom; contrarily, when the medical solution container body is squeezed lightly, a small amount of medical solution is absorbed into the brush and is then extracted therefrom.

However, such a conventional medical solution applying container has had a drawback of difficulty in adjusting the extraction amount of medical solution.

For example, a user with a relatively weak grip cannot pinch or squeeze the medical solution container body with an appropriate level of grip even if trying to adjust the extraction amount of medical solution. When the actual extraction amount of medical solution is lesser than expected, the user has to settle for the lesser amount; contrarily, when the actual extraction amount of medical solution is too much than expected, the medical solution is wasted by that much.

The present invention has been produced in view of the drawback described above. It is an object of the present invention to provide a medical solution applying container including the inside stopper.

According to the present invention, a medical solution applying container is provided according to claim <NUM> An inside stopper is attached at a lower end portion thereof to a medical solution container body for storing a medical solution. The inside stopper is provided with a brush attached to an upper end portion thereof so as to apply the medical solution. The inside stopper includes a brush inserted-and-mounted hole and a pressing-for-maintaining portion. The brush inserted-and-mounted hole is a hole to which the brush is inserted and mounted. The pressing-for-maintaining portion is provided in a lower end portion of the brush inserted-and-mounted hole. The pressing-for-maintaining portion presses a lateral periphery of the brush so as to maintain a position of the brush with respect to the inside stopper. The pressing-for-maintaining portion includes a tongue piece, and a gap is formed at the tongue piece.

The pressing-for-maintaining portion includes a plurality of tongue pieces. Besides, the plurality of tongue pieces are disposed through a plurality of gaps formed therebetween. Each of the plurality of gaps extends along the brush inserted-and-mounted hole.

Preferably, a plurality of vertical ribs are formed to extend from a surface of the lower end portion of the brush inserted-and-mounted hole to inner surfaces of the plurality of tongue pieces.

Preferably, each of the plurality of tongue pieces is provided with a hook portion directed toward the upper end portion in a contact position with the lateral periphery of the brush.

Preferably, the brush inserted-and-mounted hole is provided with a receiving portion on an upper end thereof. The receiving portion is contacted by a contact portion protruding from a middle portion of the lateral periphery of the brush.

Preferably, the brush inserted-and-mounted hole is provided with an engaging portion in a middle portion thereof. The engaging portion is engaged with the middle portion of the lateral periphery of the brush.

Preferably, the brush inserted-and-mounted hole is provided with a recessed groove on an inner surface thereof. The recessed groove extends from an opening end of the brush inserted-and-mounted hole to a lower end thereof on which the pressing-for-maintaining portion is provided.

In the inside stopper for a medical solution applying container according to the present invention, the brush inserted-and-mounted hole, to which the brush is inserted and mounted, is provided at the lower end portion thereof with the pressing-for-maintaining portion that presses the lateral periphery of the brush so as to maintain the position of the brush with respect to the inside stopper. Accordingly, depending on to what extent the lower end portion of the brush is protruded and exposed from the brush inserted-and-mounted hole to the interior of the medical solution container body in which the medical solution is stored, it is possible to adjust the amount of the medical solution permeating the lower end portion of the brush.

Consequently, the extraction amount of the medical solution can be herein easily adjusted, unlike in a conventional medical solution applying container, without necessity of adjusting the extraction amount of the medical solution depending on the level of pinching or squeezing the medical solution container body.

Referring now to the attached drawings which form a part of this original disclosure:.

An exemplary configuration of the medical solution applying container <NUM> to which the present invention is applied will be hereinafter explained with reference to drawings.

As shown in <FIG>, the medical solution applying container <NUM> is mainly composed of the medical solution container body <NUM>, the inside stopper <NUM>, the brush <NUM>, and the cap <NUM>.

As shown in <FIG>, the medical solution container body <NUM> is a closed-end tubular member having an approximately columnar shape. The medical solution container body <NUM> has an opening <NUM> provided with an inside stopper fittingly inserted portion <NUM> to which a lower end portion of the inside stopper <NUM> is fitted. Besides, the medical solution container body <NUM> is provided with a male threaded portion <NUM> on an upper end portion thereof such that the cap <NUM> is screwed thereonto.

As described above, the medical solution container body <NUM> according to the present exemplary embodiment has the approximately columnar shape; however, the shape of the medical solution container body <NUM> is not limited to this, and for instance, may be approximately prismatic or may be more complex. Besides, the material of the medical solution container body <NUM> is not particularly limited as well, and for instance, may be at least one selected from the group consisting of polypropylene (PP), polyethylene (PE), polyester (PET), and elastomer. However, polyethylene (PE) or elastomer is optimal when the medical solution applying container <NUM> is used in such a manner of dripping the medical solution from the brush <NUM>, whereas polyethylene (PE) or polyester (PET) is preferred in attempt to make a user recognize the remaining amount of the medical solution.

As shown in <FIG>, the inside stopper <NUM> is a tubular member having an approximately columnar shape and includes an inside stopper body <NUM> and a brush inserted-and-mounted hole <NUM> provided in a lengthwise center part of the inside stopper body <NUM>. Besides, the inside stopper body <NUM> is provided with an approximately circular flange <NUM> protruding from the outer periphery of an approximately middle part thereof. Moreover, the inside stopper body <NUM> is shaped such that an upper side of the flange <NUM> (a side to which the brush <NUM> is inserted and attached) has a relatively small outer diameter, whereas a lower side of the flange <NUM> (a side fitted to the medical solution container body <NUM>) has a relatively large outer diameter. It should be noted that the inside stopper body <NUM> may be shaped such that the upper side of the flange <NUM> has a relatively large outer diameter, whereas the lower side of the flange <NUM> has a relatively small outer diameter.

In the inside stopper body <NUM>, the upper side having the relatively small outer diameter is referred to as a brush attached portion <NUM>, whereas the lower side having the relatively large outer diameter is referred to as a medical solution container body attached portion <NUM>.

As described above, the inside stopper <NUM> according to the present exemplary embodiment has the approximately columnar shape; however, the shape of the inside stopper <NUM> is not limited to this, and for instance, may be approximately prismatic or may be more complex. Besides, the inside stopper <NUM> is configured to be fittingly inserted at the medical solution container body attached portion <NUM> into the inside stopper fittingly inserted portion <NUM> of the medical solution container body <NUM>; instead, the inside stopper <NUM> may be configured to be attached to the medical solution container body <NUM> such that the lower end portion of the inside stopper <NUM> is put onto the upper end portion of the medical solution container body <NUM>. Furthermore, the material of the inside stopper <NUM> is not particularly limited as well, and for instance, may be at least one selected from the group consisting of polypropylene (PP), polyethylene (PE), polyester (PET), and polybutylene terephthalate (PBT). What is required for the material of the inside stopper <NUM> is a stiffness that enables the brush <NUM> to be easily inserted into the brush inserted-and-mounted hole <NUM> and enables the medical solution container body attached portion <NUM> to be easily fittingly inserted into the inside stopper fittingly inserted portion <NUM>.

The medical solution container body attached portion <NUM> includes an inside stopper internal space <NUM>, having a greater diameter than the brush inserted-and-mounted hole <NUM>, on the inner side thereof. The inside stopper internal space <NUM> is communicated with the lower end of the brush inserted-and-mounted hole <NUM>. In the present exemplary embodiment, the brush inserted-and-mounted hole <NUM> has a circular cross section shaped to conform to the outer shape of the brush <NUM>. However, as described below, the outer shape of the brush <NUM> is not limited to be columnar, and for instance, may be prismatic; hence, the shape of the brush inserted-and-mounted hole <NUM> can be changed to conform to the outer shape of the brush <NUM>.

Besides, the brush inserted-and-mounted hole <NUM> is provided with a pressing-for-maintaining portion <NUM> protruding from the lower end portion thereof to the inside stopper internal space <NUM>. In the present exemplary embodiment, the pressing-for-maintaining portion <NUM> is composed of four tongue pieces <NUM> disposed on an approximately common imaginary circle so as to enclose the lower end portion of the brush inserted-and-mounted hole <NUM>. Moreover, the four tongue pieces <NUM> are disposed through gaps <NUM> formed therebetween. Each gap <NUM> extends along the brush inserted-and-mounted hole <NUM>.

It should be noted that the number of the tongue pieces <NUM> disposed on the approximately common imaginary circle is not limited to four and can be assumed to be, for instance, two, three, six, eight, or so forth; however, it is preferred to set the number of the tongue pieces <NUM> to be four in terms of easiness in manufacturing the inside stopper <NUM>, balance in holding the brush <NUM>, and so forth.

The four tongue pieces <NUM> are downwardly tapered to approach the center of the brush inserted-and-mounted hole <NUM>. The imaginary circle, formed by the lower ends (distal ends) of the tongue pieces <NUM>, is set to be slightly smaller than the outer shape of the brush <NUM> to be inserted and mounted to the brush inserted-and-mounted hole <NUM>. With this configuration, when the lower end of the brush <NUM> inserted into the brush inserted-and-mounted hole <NUM> reaches the pressing-for-maintaining portion <NUM>, the tongue pieces <NUM> are configured to press together the lateral periphery of the lower end portion of the brush <NUM> so as to maintain the position of the brush <NUM> with respect to the inside stopper <NUM>.

Furthermore, a plurality of vertical ribs <NUM> are provided to extend from positions, located slightly above roots <NUM> of the tongue pieces <NUM> on the inner surface of the brush inserted-and-mounted hole <NUM>, to the inner surfaces of the tongue pieces <NUM>, respectively.

As shown in <FIG>, the brush <NUM> is formed by collectively pressing a bundle of synthetic fibers having predetermined specific gravity and strength in an approximately columnar shape with a predetermined density. The medical solution L permeates the lower end portion of the brush <NUM> and is drawn to the upper end portion of the brush <NUM> by capillary action; hence, the medical solution L is configured to be applicable to a desired position on the skin or so forth by pressing the upper end of the brush <NUM> thereto.

As described above, the outer shape of the brush <NUM> according to the present exemplary embodiment has the approximately columnar shape; however, the outer shape of the brush <NUM> is not limited to this, and for instance, may be approximately prismatic or may be more complex. Besides, the material of the brush <NUM> is not particularly limited as well, and for instance, may be at least one selected from the group consisting of polyester (PET, PBT) fiber, polypropylene (PP) fiber, polyamide (PA) fiber, acrylic (PMMA) fiber, and polyacetal (POM) fiber.

As shown in <FIG>, the cap <NUM> is a member for avoiding the followings when the medical solution applying container <NUM> is stored without being used: unintended attachment of the medical solution L to an undesired object or so forth due to contact of the upper end of the brush <NUM> therewith; and unintended evaporation or so forth of the medical solution L through the upper end of the brush <NUM>.

The cap <NUM> according to the present exemplary embodiment has an approximately conical shape and includes a brush accommodation space <NUM> on the inner side thereof to accommodate the distal end portion of the brush <NUM>. Besides, the cap <NUM> is provided with a female threaded portion <NUM> on the lower end portion of the inner surface thereof to be screwed onto the male threaded portion <NUM> of the medical solution container body <NUM> (see <FIG>).

As described above, the outer shape of the cap <NUM> according to the present exemplary embodiment has the approximately conical shape; however, the outer shape of the cap <NUM> is not limited to this, and for instance, may be approximately prismatic or columnar shape, or alternatively, may be more complex. Besides, the material of the cap <NUM> is not particularly limited as well, and for instance, may be at least one selected from the group consisting of polypropylene (PP), polyethylene (PE), and acrylonitrile butadiene styrene (ABS) as long as the material is not extremely inferior in moisture-proofing performance and in stiffness for preventing reduction in torque required for opening the cap <NUM>.

Referring back to <FIG>, a procedure for assembling the medical solution applying container <NUM> according to the present exemplary embodiment will be briefly explained. The medical solution container body <NUM> is preliminarily filled up with a predetermined amount of medical solution L. Next, the medical solution container body attached portion <NUM> of the inside stopper <NUM> is fittingly inserted into the opening <NUM> of the medical solution container body <NUM>. Insertion of the inside stopper <NUM> into the medical solution container body <NUM> continues until the flange <NUM> thereof is contacted to the end surface of the opening <NUM>. Thereafter, the brush <NUM> is gradually inserted, from the lower end thereof, into the brush inserted-and-mounted hole <NUM> of the inside stopper <NUM>. Insertion of the brush <NUM> into the inside stopper <NUM> continues to a position that the outer peripheral surface of the brush <NUM> is pressed and held by the respective tongue pieces <NUM> composing the pressing-for-maintaining portion <NUM>. Finally, the cap <NUM> is set to cover the distal end portion of the brush <NUM>. In this way, assemblage of the medical solution applying container <NUM> is completed.

The procedure for assembling the medical solution applying container <NUM> is not limited to the above. For example, the brush <NUM> may be preliminarily fitted into the inside stopper <NUM>; thereafter, the medical solution container body attached portion <NUM> of the inside stopper <NUM> may be fittingly inserted into the opening <NUM> of the medical solution container body <NUM>. Alternatively, the inside stopper <NUM> may be attached to the medical solution container body <NUM>; thereafter, the medical solution container body <NUM> may be filled up with the medical solution L through the brush inserted-and-mounted hole <NUM> of the inside stopper <NUM>.

In the inside stopper <NUM> for the medical solution applying container <NUM> according to the present exemplary embodiment, the brush inserted-and-mounted hole <NUM>, to which the brush <NUM> is inserted and mounted, is provided at the lower end portion thereof with the pressing-for-maintaining portion <NUM> that presses the lateral periphery of the brush <NUM> so as to maintain the position of the brush <NUM> with respect to the inside stopper <NUM>. Accordingly, depending on to what extent the lower end portion of the brush <NUM> is protruded and exposed from the brush inserted-and-mounted hole <NUM> to the interior of the medical solution container body <NUM> in which the medical solution L is stored, it is possible to adjust the amount of the medical solution L permeating the lower end portion of the brush <NUM>.

Consequently, the extraction amount of the medical solution L can be herein easily adjusted, unlike in a conventional medical solution applying container, without necessity of adjusting the extraction amount of the medical solution L depending on the level of pinching or squeezing the medical solution container body <NUM>.

Besides, the pressing-for-maintaining portion <NUM> in the inside stopper <NUM> is composed of the plural tongue pieces <NUM> disposed through the gaps <NUM> formed therebetween. Each gap <NUM> extends along the brush inserted-and-mounted hole <NUM>. Accordingly, even when the medical solution L, stored in the medical solution container body <NUM>, reduces in amount and is thereby disabled to permeate the brush <NUM> from the lower end surface thereof, the medical solution L is enabled to permeate the brush <NUM> from the outer peripheral surface of the lower end portion thereof through the gaps <NUM>; hence, it is possible to provide the medical solution applying container <NUM> that the medical solution L, stored in the medical solution container body <NUM>, can be easily used up without being left.

Furthermore, the vertical ribs <NUM> are provided to extend from the surface of the lower end portion of the brush inserted-and-mounted hole <NUM> to the inner surfaces of the tongue pieces <NUM>, whereby each tongue piece <NUM> bends lesser at the root portion thereof (in the vicinity of the lower end portion of the brush inserted-and-mounted hole <NUM>) but bends greater at the distal end portion thereof (the lower end portion of each tongue piece <NUM>). With the configuration, even when the surface hardness is not uniform among products of the brush <NUM> because of difference in material and density among the products, a pressing-for-maintaining force acting on the brush <NUM> can be appropriately maintained.

In the exemplary embodiment described above, the pressing-for-maintaining portion <NUM> of the inside stopper <NUM> is formed by disposing the plural tongue pieces <NUM> to be aligned on the approximately common imaginary circle. Instead of this, as shown in <FIG>, the pressing-for-maintaining portion <NUM> may have a continuous approximately cylindrical shape without being divided into the tongue pieces <NUM>.

Alternatively, as shown in <FIG>, each tongue piece <NUM> may be provided with a hook portion <NUM>, directed toward the upper end portion of the brush <NUM>, in a contact position with the lateral periphery of the brush <NUM>.

With the hook portions <NUM> formed as described above, it is made possible to produce a condition that the hook portions <NUM> lightly bite into the lateral periphery of the lower end portion of the brush <NUM>. Therefore, the modification <NUM> is preferred in that when the medical solution applying container <NUM> is used by the user, occurrence of the following situation can be avoided: when the distal end portion of the brush <NUM> is pressed onto the skin or so forth, the brush <NUM> is deeply retracted into the inside stopper <NUM> without being intended by the user.

Furthermore, as shown in <FIG>, the brush <NUM> is provided with a step <NUM> on the lateral periphery of the lower end portion thereof. The step <NUM> is hooked by the hook portions <NUM> provided in the inside stopper <NUM> as shown in <FIG>. Therefore, the modification <NUM> is preferred in that it is made possible to precisely determine to what extent the brush <NUM> is fitted into the inside stopper <NUM>; simultaneously, it is made possible to more reliably avoid the situation that the brush <NUM> is deeply retracted into the inside stopper <NUM> without being intended by the user.

Alternatively, as shown in <FIG>, the brush <NUM> is provided with a contact portion <NUM> protruding from an approximately middle portion of the lateral periphery thereof, whereas the inside stopper <NUM> is provided with a receiving portion <NUM>, contacted by the contact portion <NUM>, on the upper end of the brush inserted-and-mounted hole <NUM> (the upper end surface of the brush attached portion <NUM>) as shown in <FIG>. Therefore, the modification <NUM> is preferred in that it is made possible to precisely determine to what extent the brush <NUM> is fitted into the inside stopper <NUM>; simultaneously, it is made possible to more reliably avoid the situation that the brush <NUM> is deeply retracted into the inside stopper <NUM> without being intended by the user.

Alternatively, as shown in <FIG>, the inside stopper <NUM> may be provided with an engaging portion <NUM> on a middle portion of the brush inserted-and-mounted hole <NUM> so as to be engaged with a middle portion of the lateral periphery of the brush <NUM>.

Specifically, as shown in <FIG>, it can be assumed that the inside stopper <NUM> is provided with a protruding portion inwardly protruding from the entire circumference of the middle portion of the brush inserted-and-mounted hole <NUM> as the engaging portion <NUM>, whereas the brush <NUM> is provided with a recessed portion <NUM> on the entire circumference of an approximately middle portion thereof located in correspondence to the engaging portion <NUM> so as to be engaged therewith.

Contrarily, the inside stopper <NUM> may be provided with a recessed portion on the entire circumference of the middle portion of the brush inserted-and-mounted hole <NUM> as the engaging portion <NUM>, whereas the brush <NUM> may be provided with a protruding portion protruding outward from the entire circumference of the approximately middle portion thereof located in correspondence to the engaging portion <NUM>.

Consequently, the modification <NUM> is preferred in that it is made possible to precisely determine to what extent the brush <NUM> is fitted into the inside stopper <NUM>; simultaneously, it is made possible to reliably avoid the situation that the brush <NUM> is deeply retracted into the inside stopper <NUM> without being intended by the user and a situation that the brush <NUM> is protruded from the inside stopper <NUM> to an extent not intended by the user.

Alternatively, as shown in <FIG>, the pressing-for-maintaining portion <NUM> of the inside stopper <NUM> may be provided with a plurality of protruding portions <NUM> protruding from the inner surface of the brush inserted-and-mounted hole <NUM> toward the center of the brush inserted-and-mounted hole <NUM> so as to clog in part the brush inserted-and-mounted hole <NUM>. In this case, as shown in <FIG>, the lower end portion of the brush <NUM> is shaped to be fitted to gaps between the pressing-for-maintaining portion <NUM> (the protruding portions <NUM>) and the brush inserted-and-mounted hole <NUM> without contacting the pressing-for-maintaining portion <NUM> (the protruding portions <NUM>) clogging in part the brush inserted-and-mounted hole <NUM>.

Consequently, the modification <NUM> is preferred in that it is made possible to prevent occurrence of a situation the brush <NUM> is rotated with respect to the inside stopper <NUM> without being intended by the user.

It should be noted that the following configuration may be provided as an alternative example of the modification <NUM>. As shown in <FIG>, the pressing-for-maintaining portion <NUM> may be shaped to stretch from one side to another on the inner surface of the brush inserted-and-mounted hole <NUM> so as to traverse the cross-sectional middle of the brush inserted-and-mounted hole <NUM>.

Alternatively, as shown in <FIG> and <FIG>, the tongue pieces <NUM>, composing the pressing-for-maintaining portion <NUM>, may be set to be located on the upper side in the inside stopper body <NUM>; namely, the tongue pieces <NUM> may be shifted to shorten the dimension of the brush inserted-and-mounted hole <NUM> in the up-and-down direction. For example, in the modification <NUM>, the pressing-for-maintaining portion <NUM> (the tongue pieces <NUM>) is set to be located on the upper side of the flange <NUM>.

Likewise in the inside stopper <NUM> according to the modification <NUM>, as shown in <FIG>, the brush <NUM> is gradually inserted, from the lower end thereof, into the brush inserted-and-mounted hole <NUM> of the inside stopper <NUM>. Insertion of the brush <NUM> into the inside stopper <NUM> continues to a position that the outer peripheral surface of the brush <NUM> is pressed and held by the respective tongue pieces <NUM> composing the pressing-for-maintaining portion <NUM>.

Accordingly, depending on to what extent the lower end portion of the brush <NUM> is protruded and exposed from the lower end of the brush inserted-and-mounted hole <NUM> (i.e., the lower ends of the tongue pieces <NUM>) toward the medical solution container body <NUM>, it is possible to adjust the amount of the medical solution L permeating the lower end portion of the brush <NUM>.

Alternatively, as shown in <FIG>, the inside stopper <NUM> may be provided with a plurality of recessed grooves <NUM> on the inner surface of the brush inserted-and-mounted hole <NUM>. Each recessed groove <NUM> extends in a vertical direction from the opening end of the brush inserted-and-mounted hole <NUM> (the upper side in the drawings), into which the brush <NUM> is inserted and mounted, to the bottom end (the lower end) of the brush inserted-and-mounted hole <NUM> (the lower side in the drawings) on which the tongue pieces <NUM> (the pressing-for-maintaining portion <NUM>) are provided. It should be noted that the number of the recessed grooves <NUM> may be single or plural. Moreover, each recessed groove <NUM> may be shaped straight as depicted in the drawings, or alternatively, may be shaped to be bent or curved.

When the medical solution applying container <NUM> is used after assembled, the medical solution L contained in the medical solution container body <NUM> is caused to permeate the brush <NUM> from the lower end portion thereof to the distal end thereof and is then applied to the skin or so forth. At this time, the recessed grooves <NUM> are provided to extend in the vertical direction from the opening end to the bottom end of the inner surface of the brush inserted-and-mounted hole <NUM>; hence, the external air is likely to enter the medical solution container body <NUM> through the recessed grooves <NUM>, whereby the medical solution L is enabled to permeate the brush <NUM> and reach the distal end thereof as much as possible.
