Abstract

PURPOSE:To apply a liquid to the wide affected part within a short time by opening a container to expose a coating member formed so that the thickness of the shape of the leading end surface thereof is larger than that thereof in the direction crossing one direction at a right angle and moving the leading end surface of the coating member in the orthogonal direction. CONSTITUTION:A container 5 is opened by breaking an opening means. As a result, the container main body 3 is separated into an inclined cylindrical part 3a and a horizontal cylindrical part 3b and a coating member 8 is exposed from the leading end of the inclined cylindrical part 3a. When a liquid 3 is applied to the affected part, the coating pressure of the coating member 8 is held to constant pressure by elastic springs 9, 9 so as not to apply the liquid 6 to the affected part to a necessary degree or more. Since this coating member 8 has an almost diamond shape, the thickness in one direction thereof, for example, alpha is larger than the thickness beta in the direction crossing one direction at a right angle. Therefore, when the coating member 8 is moved in the direction shown by an arrow A, the liquid 6 can be applied to the affected part over a wide range by one coating operation.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention comprises a container containing a liquid such as a disinfectant, and an applicator that is housed and held in the container and applies the liquid, and can be carried outdoors, etc. Alternatively, the present invention relates to a liquid applicator that is always kept at home and can be used to apply a liquid such as a disinfectant to an affected area by opening the container when necessary.

[Prior Art] Disinfection treatment methods used in emergencies such as external injuries or insect bites, or at home, generally involve impregnating an applicator such as absorbent cotton with a liquid such as a disinfectant in a medicine bottle, and wiping or cleaning the affected area with it. Liquid is often applied.

In addition, as a simple liquid applicator that eliminates the trouble of handling in this case, a liquid exuding applicator is provided at the mouth of a liquid container for disinfectant, etc., and this allows the liquid such as disinfectant to be applied directly to the affected area. There have been provided products that are capable of spraying these liquids, products that are equipped with a mechanism for spraying these liquids, and products that are packaged with a napkin-like application member made of nonwoven fabric or the like impregnated with these liquids.

Therefore, we have recently integrated the advantages of these conventional products and developed the 8th product as a liquid applicator that is easy to handle and hygienic.
A liquid applicator a as shown in the figure has been proposed (see Japanese Unexamined Patent Publication No. 181776/1983). It is stored in a sealed container. This container consists of a dropper part d and a container body e, which are joined at an open end f of the container body e. The container body e is composed of a large diameter part e and a narrow diameter part e2 connected to the large diameter part e, and an opening means g is formed in the narrow diameter part e (see FIG. 8(a)). This liquid applicator a uses an exposed column-shaped applicator member to unseal the container (opening means g) when necessary, and applies a liquid such as disinfectant directly to the affected area. (See FIG. 8(C)) There is also a liquid applicator 2a as shown in FIG.
30572).

This liquid applicator 2a is formed in substantially the same manner as the liquid applicator a shown in FIG. 8, but the columnar applicator member is formed longer. In order to support this long application member, a reinforcing core material i is inserted into the application member.

This reinforcing core material i is used when opening the container.

It has elasticity to the extent that it can be bent, and when applying it to the affected area with the application part k on the side of the application member excluding the tip part j,
It has enough rigidity to support the coating member.

Therefore, when necessary, this liquid applicator 2a can be used to unseal the opening means g of the container. ), and the liquid can be applied to a wide area of the affected area by applying the liquid several times.

[Problems to be Solved by the Invention] However, in the liquid applicator a as described above, the columnar applicator member is made by fixing a large number of acetylcellose long fibers into a bundle to form a columnar shape as a whole. , a porous material such as a sponge is used. Therefore, since the pillar-shaped application member has a weak stiffness and it is difficult to lengthen the exposed part, the application part mainly uses the distal end surface. ), it had to be applied over time. It is also possible to increase the diameter of the column-shaped applicator member and apply it to a wide affected area in a short time, but this increases the diameter of the container body e and therefore the overall size, making storage and storage difficult. This becomes inconvenient when carrying it outdoors.

In addition, the liquid applicator 2a made by the present applicant can apply liquid to a wide range of affected areas by applying the liquid several times, but the structure is relatively complicated and the overall length is shortened due to the length of the applicator member. There were some inconveniences such as the length of the text.

Therefore, the present invention was made in view of the above circumstances, and
To provide a liquid applicator, which has a simple structure and is approximately the same in overall length as a conventional one, and which can apply liquid to a wide affected area in a short time without getting the liquid on the fingers after opening the package. With the goal.

[Means to solve the problem]

In order to solve the above problems, the liquid applicator of the present invention includes a container that stores a liquid, and an applicator that is housed and held in the container and is capable of applying the liquid. A liquid applicator capable of applying the liquid by exposing an application member, wherein the shape of the distal end surface of the application member is such that the thickness in one direction thereof is larger than the thickness in a direction perpendicular to the one direction. It is being formed.

[Function] According to the liquid applicator configured as described above, the container is opened by breaking a predetermined portion of the container, and the thickness of the tip surface shape in one direction is greater than the thickness in the direction orthogonal to the one direction. By exposing the large applicator member and moving the exposed distal end surface of the applicator member in the orthogonal direction, the liquid can be applied to a wide affected area in a short time.

[Example] Hereinafter, an example of the present invention will be described in detail based on FIGS. 1 to 7.

FIG. 1 is a perspective view showing a liquid applicator of the present invention, FIG. 2 is a half-cut longitudinal sectional view showing the liquid applicator, and FIG. 3 is a half-cut longitudinal sectional view showing the container body of the liquid applicator in an unsealed state. FIG. 4 is a side view taken along line I'V-IV in FIG. 3. The liquid applicator l is composed of a cap part 2 made of a hard plastic material and having a substantially rhombic cross section, and a container body 3 made of a hard plastic material and having a substantially rhombic cross section. A container 5 formed by joining, and the container 5
It consists of a liquid 6 such as a disinfectant contained therein and a substantially diamond-shaped application member (hereinafter simply referred to as application member) 8 having a tip end surface 7 for applying the liquid 6. A first spring 9.9 is fixed to the cap portion 2, and a diamond-shaped plate 10 is fixed to the tip of the spring 9.9, and a hole 10a is bored in the diamond-shaped plate 10. . On the other hand, the container main body 3 is composed of an inclined cylinder part 3a having an inclined wall surface and a horizontal cylinder part 3b connected to the inclined cylinder part 3a, and an opening means 11 having a thin peripheral wall is formed in a part of the inclined cylinder part 3a.

A liquid 6 such as a disinfectant is hermetically stored in the hollow portion of the inclined cylinder portion 3a as shown in FIG. Further, the application member 8 is housed in a hollow portion of the inclined cylinder portion 3a of the container body 3, which is formed into a substantially diamond shape, as shown in the drawing. That is, the coating member 8 has its peripheral surface portion held by the inclined wall surface of the inclined cylinder portion 3a, and its base end portion supported by the diamond-shaped plate IO.

This diamond-shaped plate 10 has a hole 10a through which the liquid 6 passes, so that the liquid 6 can be smoothly supplied to the application member 8. Furthermore, when applying the liquid 6 to the affected area, The application pressure of the application member 8 is maintained at a constant pressure by the elastic spring 9.9, so that the liquid 6 is not applied to the affected area more than necessary. Also, since the coating member 8 has a substantially rhombic shape, its thickness in one direction, for example α in FIG. 4, is greater than the thickness in a direction perpendicular to the direction, for example β in FIG. The applicator member 8 is formed to be large, so when it is moved in the direction of the arrow A in FIG. 4, the liquid 6 can be applied to a wide range of the affected area in one application operation. The ratio between α and β (α/β) is preferably 3 to 1.2. If it exceeds 3, it will be difficult to open the unsealing means 11, and if it does not reach 1.2, the coating area will be small, which is undesirable. It is made of hard plastic material with low permeability. It is desirable that the cap portion 2 and the container body 3 be made of the same type of hard plastic material in order to allow ultrasonic welding. The material is injection molded using polypropylene homopolymer.
Each part is individually molded by extrusion molding, blow molding, injection blow molding, vacuum molding, etc. In addition, the container body 3 and the cap part 2 must be firmly joined to form the container 5 while the liquid 6 is contained in the hollow part of the inclined cylinder part 3a. In this case, the hard plastic material used must be of the same series. By doing so, ultrasonic welding becomes possible and a strong bond can be achieved.

In the container main body 3 of the container 5, a horizontal cylindrical portion 3b located slightly on the side opposite to the cap portion 2 from the approximate midpoint of the entire length in the longitudinal direction,
The opening means 11 is provided. This opening means 11
is the thinner part of the peripheral wall, 0.05~0.5□
The thickness is preferably set to 0.1 to 0.2 □. The shape of the unsealing means 11 is, for example, a V-shaped groove as shown in FIG. 2, and the radius of curvature of the groove bottom is made as small as possible. It is important that the unsealing means 11 is designed so that stress is concentrated on the bottom of the groove and easily breaks only when force is applied to the container body 3 from the lateral direction in a bending direction.

The container 5 is opened by grasping both sides of the unsealing means 11 with both hands, placing the thumbs of both hands on both sides of the unsealing means 11, and applying force in the bending direction to the container body 3, thereby breaking the unsealing means 11. Ru. As a result, the container main body 3 of the container is separated into an inclined cylindrical portion 3a side and a horizontal cylindrical portion 3b side, as shown in FIG. Then, the application member 8 is exposed from the tip of the inclined cylindrical portion 3a as shown in FIG. 3. That is, the applicator member 8 is located on the side of the inclined cylinder portion 3a, and the tip surface 7 thereof is exposed by about 3 to 5n+m from the unsealing means 11, so that the applicator member 8
When the approximately diamond-shaped distal end surface 7 is moved in the direction of arrow A in FIG. 4, the liquid 6 can be easily applied in a short time even to a wide affected area.
It can be dripped and wiped off.

The material of the application member 8 is preferably one that has good permeability to the liquid 6, is inert to the liquid 6, has good shape retention, has a pleasant feel when applied to the skin, and does not cause pieces of the application member to come out. For example, a material in which a large number of acetylcellulose-based long fibers are fixed into a bundle to form an elliptical columnar shape as a whole, or a porous material can be used.

In the inclined cylinder part 3a which has been unsealed by the above-mentioned unsealing means 11, the application member 8 of the liquid applicator l is in the third position.
As shown in the figure, when a force in the direction of arrow B is applied, that is, when the application state is reached, the application member 8 causes the resilient spring 9.
Pressure is applied to the liquid 6 on the left side in FIG. 3 against the spring force 9. For this reason, the liquid 6 is poured out from the hole 10a of the diamond-shaped plate IO, the liquid 6 penetrates into the application member 8, and the liquid 6 is applied to the required location with the tip surface 7 of the application member 8, dripped, and cleaned. It can be wiped.

The method for assembling the liquid applicator 1 of the present invention is to first insert the applicator member 8 into the container body 3 from the open end 4 side, then store the liquid 6, and use the elastic spring 9 with the diamond-shaped plate lo fixed to the tip. , 9 are fixed, and the cap portion 2 is joined by ultrasonic welding at the brim-like portion of the open end 4.

Next, the operation of the liquid applicator 1 having the above structure will be explained. This liquid applicator l includes a cap portion 2 and a container body 3.
The cap part 2 and the container body 3 are made of hard plastic, so that the applicator member 8 can be used during use.
Functions as a gripping part. Moreover, since the cap part 2 and the container body 3 are hard, the liquid 6 contained in the container body 3
In order to actively extrude the container body 3, the open end 4
The resilient spring 9.9 of the cap portion 2 attached to the cap part 2 functions.

That is, as shown in FIG.
While the liquid 6 in the container 5 can be pressed and supplied to the outside through the application member 8 exposed at one end inside the container body 3,
Usually, the opening means 11 acts to open the
This opening is performed by grasping the cap part 2 of the container 5 and the inclined cylinder part 3a and the horizontal cylinder part 3b of the container body 3 with both hands, and placing the five fingers of both hands on both sides of the unsealing means 11, respectively. 5 so as to bend it at the position of the opening means II.
This is done by applying force with one's fingers and tearing the thin wall of the opening means 11 from one side, thereby separating the horizontal cylindrical part 3b from the inclined cylindrical part 3a (see FIG. 5).

A part of the application member 8 is exposed on the side of the inclined cylinder part 3a from which the horizontal cylinder part 3b has been removed by opening the container 5 described above, and as shown in FIG. The distal end surface 7 formed on the surface has a shape suitable for application to a wide range of affected areas. That is, by moving the approximately diamond-shaped distal end surface 7 of the exposed portion of the applicator 8 in the direction shown in FIG. Can apply liquid. Further, since the distal end surface 7 of the applicator 8 in the E direction in FIG. 6 can serve the same role as the tip of the brush tip, the applicator can be shaped to allow application even to narrow affected areas. Then, the liquid 6 is applied to this application member 8.
Since the applicator member 8 is hermetically stored on the side of the inclined cylinder 3a where the liquid 6 is stored, the applicator 8 is moistened with the liquid 6 in this state, so the liquid 6 can be applied to the required area without any modification. Can be wiped with liquid 6.

On the other hand, when the application pressure is increased, the application member 8 moves the diamond-shaped plate 10 to the left side in FIGS. For this reason, the liquid 6 can appropriately wet the application member 8.

In addition, the tip of the horizontal cylindrical portion 3b that is separated when the package is opened is configured to be hollow (see FIGS. 2 and 3).
Since the distal end portion of the cap can be used as a cap that fits into the inclined cylinder portion 3a, it can be used multiple times (see FIG. 7).

2. In this embodiment, a case was explained in which a disinfectant was stored as the liquid 6, but the present invention is not limited to this.
The liquid stored in the container 5 of the liquid applicator 1 of the present invention is
Items used in daily life, such as cosmetic liquids and detergent liquids, can be stored as appropriate.

Effects of the Invention] As detailed above, in the liquid applicator of the present invention, at least the shape of the distal end surface of the applicator for applying an affected area is such that the thickness in one direction is the same as the thickness in the direction perpendicular to the one direction. Since the container is larger in size, if you break a part of the container, open the container, expose the applicator, and move the distal end of the applicator using the wider side, you can apply a short cut to a wide affected area. Liquid can be applied in hours. In other words, although the liquid applicator of the present invention has a simple structure and an overall length in the axial direction that is approximately the same as that of the conventional one, the liquid applicator does not adhere to the fingers after opening the package, and can be applied to a wide range of affected areas in a short time. It has the effect of being able to apply liquid.
