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 can be 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.

[Conventional technology]

Disinfection treatment methods for 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 from a medicine bottle.
This is often followed by applying a cleansing test or liquid to the affected area.

In this case, as a simple liquid applicator that eliminates the trouble of handling, a liquid exuding applicator is provided at the opening of the 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 can spray these liquids, products that are equipped with a mechanism for spraying these liquids, and products that are hermetically packaged napkin-like applicator members made of nonwoven fabric or the like impregnated with these liquids.

Therefore, recently, a liquid applicator a as shown in Fig. 8 has been considered as a liquid applicator that is easy to handle and hygienic by comprehensively integrating the advantages of these conventional products (Japanese Patent Laid-Open No. 63-181776 (see publication).
This liquid applicator a has a container b that seals and stores a liquid c such as a disinfectant solution for one-time use. This container b consists of a dropper part d and a container body e,
It is constructed by joining these at the open end f of the container body e. This container body e has a large diameter part.
Consisting of e ₁ and a narrow diameter section e ₂ connected to this, the narrow diameter section
An unsealing means g is formed in _e2 (see Fig. 8a). When necessary, this liquid applicator a unseals the opening means g of the container b (see Fig. 8B), and uses the exposed columnar applicator h to directly apply liquid b such as disinfectant to the affected area. (See Figure 8c).

There is also a liquid applicator 2a as shown in FIG. 9 by the applicant of the present application (see Japanese Patent Application No. 01-30572). This liquid applicator 2a is formed in substantially the same manner as the liquid applicator a shown in FIG. 8, but the columnar applicator h is formed longer. A reinforcing core material i is inserted into the coating member h to support the long coating member h.

This reinforcing core material i has elasticity to the extent that it can be bent when the container b is opened, and when it is applied to the affected area by the application part k on the side surface excluding the tip j of the application member h. It has enough rigidity to support.

Therefore, this liquid applicator 2a can be used as a container b when necessary.
It is possible to open the opening means g (see Figure 9B) and apply the coating to the affected area using the exposed application part k of the application member h (see Figure 9C). It is possible to apply liquid to a certain area.

[Problem to be solved by the invention]

However, in the liquid applicator a described above, the columnar applicator k is made of a cylindrical material made by fixing a large number of acetylcellose-based long fibers into a bundle, or a porous material such as a sponge. are using. Therefore, since the columnar application member h has a weak stiffness and it is difficult to lengthen the exposed part of the application member h, the distal end surface is mainly used as the application part k. As shown in c,
I had to spend a lot of time applying it. or,
Although it is possible to increase the diameter of the column-shaped applicator h and apply it to a wide affected area in a short time, 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.

Further, the liquid applicator 2a by the present applicant includes a container b.
Since the diameter of the container body e is small, the unsealing means g can be opened easily, and the liquid can be applied to a wide range of the affected area in one application. However, there were disadvantages such as the structure being relatively complicated and the overall length increasing due to the length of the coating member h.

The present invention was developed in view of the above circumstances, and has a simple structure, the overall length is approximately the same as the conventional one, and is capable of applying liquid to a wide affected area in a short time. However, it is an object of the present invention to provide a liquid applicator that makes it easy to open the container by breaking the container at a broken point.

[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. The liquid applicator is capable of applying the liquid by exposing the applicator member, and the cross-sectional shape of at least the broken part of the container is formed into a substantially elliptical shape.

[Effect]

According to the liquid applicator having the above structure, since the cross-sectional shape of the break point of the container is formed into a substantially elliptical shape, when an external force is applied to the break point to cause the break, the external force is not dispersed but concentrated at one point. The container easily ruptures and cracks occur at the point where the external force is concentrated, and the rupture progresses rapidly while the external force concentrates at the point where the container is rupturing, until the container is completely ruptured and the container is opened. I can do it.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to 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 seen from the - line direction of FIG. 2. The liquid applicator 1 includes a cap portion 2 made of hard plastic material and having a substantially diamond-shaped cross section.
and a container body 3 made of a hard plastic material and having a substantially rhombic cross section, and a container 5 formed by joining these at the open end 4 of the container body 3, and the container 5.
It consists of a liquid 6 such as a disinfectant contained therein and a substantially elliptical application member (hereinafter simply referred to as application member) 8 having a tip end surface 7 for applying the liquid 6. Resilient springs 9, 9 are fixed to the cap portion 2, and a diamond-shaped plate 10 is fixed to the tips of the resilient springs 9, 9, and a hole 10a is bored in this diamond-shaped plate 10. . On the other hand, the container body 3
consists of an inclined cylindrical part 3a with an inclined wall surface and a horizontal cylindrical part 3b connected to the inclined cylindrical part 3a, and an opening means (breakage point) 11 is formed in a part thereof by reducing the inner thickness of the peripheral wall.

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 cylindrical portion 3a of the container body 3, which is formed into a substantially oval 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 rhombic portion 10.

This diamond-shaped plate 10 has holes 10a through which the liquid 6 passes.
Since it is perforated, the liquid 6 can be smoothly supplied to the application member 8, and 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 elastic springs 9, so that the liquid 6 is not applied to the affected area more than necessary. Further, since the application member 8 has a substantially elliptical shape, α ₁ in FIG. 4 is larger than β ₂ . Therefore, when the application member 8 is moved in the direction of the arrow A in FIG. 6, the liquid 6 can be applied to a wide range of the affected area by one application action. Thus, the cap part 2 and the container body 3
is made of a hard plastic material that is inert to the liquid 6 and has 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 because they can be ultrasonically fused. Therefore, as a preferred example, a polypropylene homopolymer is used as the hard plastic material, and each part is molded by injection molding, extrusion molding, blow molding, injection blow molding, vacuum molding, or the like. Note that 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, but in this case, the hard plastic material used is the same. When made in series, ultrasonic welding becomes possible and a strong bond can be achieved.

The container body 3 of the container 5 is provided with the unsealing means 11 in a horizontal cylindrical portion 3b located slightly on the side opposite to the cap portion 2 from approximately the midpoint of its entire length in the longitudinal direction. This unsealing means 11 is a thinned portion of the peripheral wall, and has a thickness of 0.05 to 0.5 mm, preferably 0.1 to 0.2 mm.
It is provided with a thickness of The cross-sectional shape of this unsealing means 11 is approximately elliptical as shown in FIG. 4B. However, since it is difficult to form only the opening means 11 into a substantially elliptical shape in terms of the molding process of the container body 3, the cross-sectional shape of the container body 3 near both sides of the opening means 11 is as shown in FIGS. 4A and 4C. It is approximately elliptical, and the other portion is approximately diamond-shaped as described above. The elliptical shape of the unsealing means 11 preferably has a ratio of αo to βo (αo/βo) of 3 to 1.2 in FIG. 4B. If it exceeds 3, it is difficult to break the unsealing means 11, and if it does not reach 1.2, it is easy to break it, but with the application member 8 that matches the shape of this unsealing means 11, a wide area can be coated. It becomes difficult to distinguish between the surface and the surface on which a narrow area is to be coated. Moreover, the substantially elliptical shape includes an oval shape. This unsealing means 11 is
For example, a V-shaped groove as shown in FIG. 2 is used, and the radius of curvature of the groove bottom is made as small as possible. This opening means 11 is normally not susceptible to force, and only when a bending force is applied to the container body 3 from the lateral direction.
It is important to concentrate stress on the groove bottom to make it easy to break out.

Therefore, when an external force is applied to the unsealing means 11 to break it, since the cross-sectional shape of the unsealing means 11 is formed into a substantially elliptical shape, there is no part where the cross section is a straight line as in the case of a diamond-shaped case, for example, and all of the unsealing means 11 is broken. Because it is a curved line, the part of the unsealing means 11 where the external force is concentrated will break and crack, the external force will always concentrate on the part that is about to break, the break will progress rapidly, and eventually the unsealing means 11 will be completely broken. It will be opened on. On the other hand, if the cross-sectional shape of the unsealing means 11 is diamond-shaped, the external force is applied to the straight portion, so the external force is dispersed by the straight portion and difficult to concentrate at one point. Even if the unsealing means 11 breaks and cracks, the external force is difficult to concentrate on the part where the unsealing means 11 is breaking, so the breakage is difficult to proceed, and the unsealing means 1
The non-separable part 1 tends to remain and is difficult to open.

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 body 3 of the container 5 is separated into the inclined cylinder part 3a side and the horizontal cylinder part 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 application member 8
is located on the side of the inclined cylinder part 3a, and its tip surface 7 is exposed from the opening means 11 by about 3 to 5 mm,
When the approximately elliptical distal end surface 7 of the application member 8 is moved in the direction of arrow A in FIG. 6, the liquid 6 can be easily applied, dripped, and wiped in a short time even on a wide affected area. .

The material of the application member 8 has good permeability to the liquid 6;
Preferably, it is inert to the liquid 6, has good shape retention, has a pleasant feel when applied to the skin, and does not easily cause pieces of the application member to come out. For example, it is possible to use 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.

When the application member 8 of the liquid applicator 1 is applied with a force in the direction of the arrow B as shown in FIG. In this state, the application member 8 applies pressure to the liquid 6 on the left side in FIG. 3 against the spring force of the elastic springs 9, 9. Therefore, the liquid 6 is poured out from the hole 10a of the diamond-shaped plate 10, the liquid 6 penetrates into the application member 8, and the liquid 6 is applied to the required location with the distal end surface 7 of the application member 8.
Can be dripped and wiped.

The method for assembling the liquid applicator 1 of the present invention is as follows:
The applicator member 8 is inserted into the container body 3 from the open end 4 side, and then the cap part 2 houses the liquid 6 and has elastic springs 9, 9 fixed to the tip thereof with a diamond-shaped plate 10 fixed thereto.
are joined by ultrasonic welding at the flange-like part of the open end 4.

Next, the operation of the liquid applicator 1 having the above structure will be explained. This liquid applicator 1 has a cap part 2.
By constructing the cap portion 2 and the container body 3 from hard plastics, the cap portion 2 and the container body 3 are made of hard plastic.
functions as a gripping portion for the application member 8 during use. Moreover, since the cap part 2 and the container body 3 are hard, in order to actively push out the liquid 6 contained in the container body 3, the opening end 4 of the container body 3 must be
The resilient springs 9, 9 of the cap part 2 attached to the cap part 2 function. That is, as shown in FIG. 3, by pressing this application member 8 in the direction of arrow B, the liquid 6 in the inclined cylinder part 3a of the container body 3 is pressed and exposed at one end side inside the container body 3. It can be supplied to the outside through the coating member 8 that is attached to the coating member 8.

On the other hand, in order to open the container 5, the unsealing means 1
1 comes into play. Normally, this opening involves opening the cap part 2 of the container 5 and the inclined cylindrical part 3a of the container body 3.
and the horizontal cylinder part 3b with both hands, place each finger of both hands on both sides of the opening means 11, and apply force to each finger so as to bend the container body 3 at the position of the opening means 11. It is done. That is, in this opening, since the cross-sectional shape of the unsealing means 11 is formed into a substantially elliptical shape, external force is easily concentrated at one point.
This is done by tearing off the thin peripheral wall of the opening means 11 from one side, completely breaking the opening means 11, and separating the horizontal cylindrical portion 3b from the inclined cylindrical portion 3a (see FIG. 5).

Therefore, by opening the container 5 described above, the horizontal cylindrical portion 3
An application member 8 is placed on the side of the inclined cylinder portion 3a from which b is removed.
As shown in FIG. 6, the distal end surface 7 of the application member 8, which is formed in a substantially elliptical shape, has a shape suitable for application to a wide affected area. That is,
By moving the approximately elliptical distal end surface 7 of the exposed portion of the applicator 8 in the direction A in FIG. can be applied. Further, since the tip end surface 7 of the applicator member 8 in the E direction in FIG. 6 can serve the same role as the tip of the brush tip,
It has a shape that allows it to be applied even to narrow affected areas. Since the liquid 6 is hermetically stored on the side of the inclined cylinder 3a where the applicator 8 is stored,
In this state, the application member 8 is moistened with the liquid 6, so that the liquid 6 can be applied to the necessary areas as it is, and the necessary areas can be wiped with the liquid 6.

On the other hand, when the application pressure is increased, the application member 8 causes the diamond-shaped plate 10 to move against the springs of the elastic springs 9.
Since the liquid 6 moves to the left in FIGS. For this purpose, the liquid 6 can suitably moisten the application member 8.

In addition, the distal end portion of the horizontal cylinder 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 horizontal cylindrical portion 3b can be used as a cap to be fitted into the inclined cylindrical portion 3a, it can be used multiple times (see FIG. 7).

In this embodiment, a case has been described in which a disinfectant is stored as the liquid 6. However, the present invention is not limited to this, and the liquid stored in the container 5 of the liquid applicator 1 of the present invention may be a cosmetic liquid. , detergent liquid, and other items used in daily life can be stored as appropriate.

〔Effect of the invention〕

As detailed above, the liquid applicator of the present invention has
Since the cross-sectional shape of at least the rupture point of the container is formed into a substantially elliptical shape, when an external force is applied to the rupture point, the external force is not dispersed but is easily concentrated in one point, and the rupture occurs at the point where the external force is concentrated. Then cracks appeared,
Further, while the external force is concentrated on the point where the container is breaking, the breakage progresses rapidly, and the breakage point of the container is completely broken, allowing the container to be opened. In other words, the liquid applicator of the present invention has a simple structure, the overall length in the axial direction is approximately the same as that of the conventional one, and can apply liquid to a wide range of affected areas in a short time. This has the effect of making it possible to easily break the rupture point and open the container.
