Description

  The present invention relates to a flip cap type double compartment tube container and a method for producing the same, and more specifically, two components that are separated and stored in a first agent and a second agent like a hair dye and mixed at the time of use. The present invention relates to a flip cap type double compartment tube container capable of squeezing a preparation at a predetermined ratio and a method for producing the same.

  As a typical example of a two-component preparation, a hair dye composed of a first agent composed of an alkali agent and a dye intermediate and a second agent of an oxidizing agent, or a first agent and a second agent of a first adhesive component. Examples thereof include a two-component adhesive composed of an adhesive component and a second agent composed of a curing accelerator. Since the structures of the hair dye container and the two-component adhesive container are essentially the same, the hair dye container will be described below.

Hair is composed of hair epidermis or cuticle laminated in scale form, fur (cortex cortex) containing a large amount of melanin pigment, and medulla (medulla) which is a porous part of the hair center Has been.
Recently, in addition to the conventional hair dyeing of white hair to black, the use of hair dyes is also increasing because of the increasing number of people who dye black hair in various hues for the purpose of expressing individuality. A variety of hair dyes are on the market,

Hair dyes are classified into bleaching agents, permanent hair dyes, semi-permanent hair dyes, and temporary hair dyes according to the purpose of use or the maintenance period of the hair dye. It is also classified into acidic hair dyes, acidic oxidative hair dyes, and alkaline oxidative hair dyes according to the chemical characteristics of the hair dyes, and can be divided into synthetic hair dyes or natural hair dyes. A widely used hair dye is a synthetic oxidized permanent hair dye.

Acid dyes and basic dyes are temporarily adsorbed on the hair, but are decolorized over time, so oxidative dyes are mainly used as permanent hair dyes (permanent hair dyes) . Oxidative dyes are oxidized together with diamine-related compounds to develop a color and are water-soluble during hair dyeing, but become insoluble by chemical reaction over time and remain in the hair.
The oxidation dye is composed of a first agent and a second agent, the first agent is a mixture of a diamine-related compound and an alkali agent that are dye intermediates, and the second agent is composed of an oxidation agent.

The dye intermediate is colored when mixed with an oxidizing agent, but various hues can be made by mixing various kinds of dye intermediates at different ratios as described below.
・ Black: p-Phenylenediamine ・ Polybrown-Black-brown: p-Toluenediamine
・ Red: Mononitro-p-phenylenediamine
・ Poly brown: p-aminophenol
・ Yellow brown: o-aminophenol
・ Dark brown-red color: p-phenylenediamine + p-aminophenol

The alkaline agent included in the dye intermediate swells and softens the hair epidermis so that the dye can easily penetrate into the furtex, and the oxidant. Promotes action.
Typical examples of alkaline agents are ammonia and monoethyl alcohol amine. Ammonia can reduce hair damage due to its long-lasting hair dyeability and volatility, but it has the disadvantage of strong odor and irritation. On the other hand, monoethyl alcohol amine is low in scalp irritation and odorless, but is a non-volatile substance, so that it may remain on the hair and cause damage to the hair, resulting in a delay in penetration into the hair.

The oxidizing agent as the second agent develops color by decolorizing melanin, which is a natural pigment distributed in a large amount in the hair furtex (cortex), and acting on a dye intermediate to produce a dye.
As the oxidizing agent, hydrogen peroxide is usually used for the purpose of bleaching for removing melanin and decolorizing it. In the case of Orientals, if bleaching is carried out without using a hair dye intermediate, melanin is not completely removed and part of the melanin remains and is dyed into tan hair.

On the other hand, the hair coloring position is the hair quality, color, hair thickness, hair damage level, temperature, distance from hair root, hair dye application time, pH of the first agent, concentration of the second agent The amount of the first agent and the second agent and the application time are particularly important factors because they are influenced by various parameters such as the amount of the first agent and the second agent.
The hair dyes currently on the market consist of a hair dye tube container containing an intermediate dye and an alkaline agent, and a tube container containing an oxidant, and the tube container is made of resin or metal. It is.

  When hair is dyed, the hair dye as the first agent and the oxidant as the second agent must be mixed at a fixed ratio. Squeeze the appropriate amount from each tube container containing, mix evenly and place on a brush. After a certain period of time, the hair is dyed with a desired hue by the reaction of the hair dye and the oxidizing agent.

Here, the hair dye as the first agent and the oxidizing agent as the second agent are usually mixed at a volume ratio of 1: 1. If the amount of the oxidizing agent that is the second agent is mixed more than the amount of the hair dye that is the first agent, decolorization of the hair is excessively advanced by a rapid reaction, or the hair is rapidly advanced. There is a risk. On the other hand, if the amount of the oxidizing agent that is the second agent is mixed with a smaller amount than the amount of the hair dye that is the first agent, the reaction proceeds very slowly, and there is a possibility that it takes a long time for hair coloring. In either case, there is a problem that the index hue guide with the passage of time becomes meaningless, and as a result, the hair cannot be dyed to the exact desired hue.
Therefore, it is very important to mix the hair dye as the first agent and the oxidizing agent as the second agent in an accurate ratio.

However, most of the hair dyes currently on the market have been decided because the hair dye as the first agent and the oxidizing agent as the second agent are put in different containers as described above. It is not easy to mix in proportion, and there are problems that it is difficult to adjust the hair coloring time of hair and obtain the desired hair color.
As a method for solving such a problem, various double compartment tube containers have been proposed as follows.

  Korean Registered Patent No. 0,467,265 (registered on 2005.11.11), separates the existing hair dye material that was filled into the first agent and the second agent separately in one tube. It proposes a double tube for filling a hair dye, which is filled and cut off at the time of use to mix different materials. Since the inner container is housed inside the outer container and the inlet part of the inner container is in close contact with the inlet part of the outer container, there is a problem that manufacturing is difficult and uneconomical. . In particular, there is a problem that it is difficult to apply to a squeezing type soft container mainly applied to cream type contents.

  Korean Patent Publication No. 2006-0081268 (published on 2006.07.12) relates to a container in which two or more kinds of contents are filled in one container, and when used, the package is broken and the filler is mixed and discharged. It is. There is a risk of damage to the package due to external force, and it is difficult to apply to cream-type contents, especially because two or more kinds of contents must be thoroughly mixed in the container. was there.

  Korean Utility Model Registration No. 0,199,207 (2000.07.29. Registration) is that the lower end of the tube container is heat-sealed to form two compartment spaces in the tube container. A hair dye tube container is proposed in which an outlet for the hair dyes A and B is formed at one end, and a screw forming lid is fastened around the outlet. This tube container is not only inferior in handling because it is fastened with a screw cap, except that two kinds of components are housed in one double container partitioned by a partition wall, and both components can be obtained by rotating the screw cap. However, there is a problem that it is easy to cause a chemical reaction by mixing inside the cap.

  The Korean registered utility model No. 0,304,903 (2003.02.06. Registered) has a discharge hole 111 formed at the upper end and an outer periphery as shown in FIGS. 00, a neck portion 11 'in which a spiral 112 is formed, an attachment surface 12' formed on the lower side of the neck portion 11 'in which no spiral 112 is formed, and a tube body 13 in which a cream type content is filled. The inner tube 10 'having a' and the two inner tubes 10 'are attached with reference to the attachment surface 12', and an adhesive is applied on the inner side to improve the attachment properties of each inner tube 10 '. And an outer tube 20 ′ that is shrunk by heat treatment and is in close contact with and integrated with the two inner tubes 10 ′, and a cover 30 ′ that is spirally coupled to the neck portion 11 ′ with the two inner tubes 10 ′ attached thereto. The double tube container characterized by including is disclosed.

This double tube container is not only inferior in handling because it is fastened with a screw cap, but also has a problem that both components are likely to mix inside the cap due to rotation of the screw cap and cause a chemical reaction. There is a problem that the manufacturing cost is increased in that the tubes 10 'and 20' are used.
Against this backdrop, a double compartment tube container that can take out a two-component preparation at a predetermined ratio and quantitatively mix the two-component preparation, is easy to open and close, and has a simple container structure and is low in production cost. Development has been requested.

The flip cap type double compartment tube container 1 according to the first practical example of the present invention is arranged at the upper outer edge of the tube container 18 divided by the lower partition 13 into the first compartment 11 and the second compartment 12. The main body 10 to which the shoulder 15 and the neck 16 having the upper partition wall 17 are fused, and a cap that extends downward in the center and has a first discharge hole 32a and a second discharge hole 32b separated by the cap partition wall 32c. The main body 31 includes a cap 34 that is coupled to the cap main body 31 by a hinge 35 and has two protrusions 34a that simultaneously open and close the first discharge hole 32a and the second discharge hole 32b. And a flip cap 30.

Here, the lower end portion of the tube container 18 forms the sealing portion 14 by an appropriate known means such as high-frequency heat fusion, and the upper end surface of the lower partition wall 13 in the tube container 18 is the same as the lower end surface of the upper partition wall 17. The shoulder 15 and the neck 16 are joined together to form a first opening 16 a and a second opening 16 b by the upper partition wall 17.
An annular protruding jaw 16c is formed on the outer week edge portion of the neck 16 to be fastened with the annular fixing portion 33 of the flip cap 30 by forced press-fitting. In the present invention, such a fastening method by forced press-fit is adopted. Therefore, the first opening 16a and the second opening 16b of the neck 16 can be accurately matched with the first discharge hole 32a and the second discharge hole 32b of the discharge part 32, respectively, without using the screw fastening type fastening method. Become.

On the other hand, an annular fixing portion 33 having an annular jaw 33b for press-fitting and fastening with the annular protruding jaw 16c of the neck 16 is formed at the center of the cap body 31, and if necessary, for a reliable conclusion. Cutout grooves (see reference numeral 33a in FIG. 4b) can be formed at positions perpendicular to the annular fixing portion 33 of the cap body 31.
In addition, for example, by forming grooves 17b and 17a at the upper end and lower end of the upper partition 17 of the shoulder 15 and neck 16, respectively, the lower end of the cap partition 32c and the upper end of the lower partition 13 are inserted. The grooves 17b and 17a can be bonded to the lower end portion of the cap partition wall 32c and / or the upper end portion of the lower partition wall 13 instead of the upper partition wall 17. Of course, it can also be formed.

At the center lower end portion of the lid 34 of the flip cap 30, the outer week-edge inclined surface of the discharge portion 32 that protrudes and extends with the first discharge hole 32 a and the second discharge hole 32 b is in contact with the inner week edge. An annular reamer 34b is formed so as to be in close contact. In addition, two protrusions 34a are formed at corresponding positions so as to open and close the first discharge holes 32a and the second discharge holes 32b.
Here, the discharge part 32 can also be formed in the planar shape as shown in FIG. 4 instead of the form extended and protruded upward like the example shown in figure.

  The annular reamer 34b and / or the protrusion 34a may be integrally formed of an equal material such as the flip cap 30, for example, polypropylene (PP), high density polyethylene (HDPE), polyethylene terephthalate (PET), or the like. However, it is more desirable to form this part with an elastomer such as a double-injected silicone rubber for more reliable airtightness. Moreover, although the shape can also be made into the cylindrical form whose edge part is a hemispherical shape, it can also be made into a substantially conical form with the outer week inclination surface of the upper and lower narrows and the whole.

Meanwhile, the tube container 18 and the lower partition wall 13 may be made of a flexible material such as low density polyethylene (LDPE) or ethylene vinyl acetate (EVA), but may be an aluminum laminated composite resin material or an aluminum thin film material. Of course, it can also be formed.
In the illustrated example, flip grooves 31b and 34c are formed in the upper front end portion of the cap body 31 of the flip cap 30 and the lower end portion of the front surface of the lid 34, respectively. The lid 34 can be opened easily and conveniently.

  Therefore, if the user presses and squeezes the tube container 18 by hand, the first agent 21 and the second agent 22 filled in the first compartment 11 and the second compartment 12 are respectively the first 16 of the neck 16. After passing through the opening 16a and the second opening 16b, an equal amount or a predetermined proportion amount (this amount) through the first discharge hole 32a and the second discharge hole 32b of the discharge portion 32 connected to the annular fixing portion 33 of the cap body 31 (this In this case, the first discharge hole 32a and the second discharge hole 32b can be discharged at a predetermined width in advance.

In the drawing, reference numeral 31c, which has not been described, is a lid resting jaw.
FIG. 3 is a partially cutaway cross-sectional view of a flip cap type double compartment tube container 1a according to a second example of the present invention, and its basic structure is the same as that of FIGS. Since this is essentially the same as this case, only the discharge unit 32 will be described.

Since the two lines of the first discharge hole 32a and the second discharge hole 32b are kinked in a mutual spiral shape, the cream-type or gel-type first agent and second agent (drawing symbols 21 and 22 in FIG. 1 respectively) Since the discharge is performed in a mutual twist mode, mixing is easier.

Next, FIGS. 4 and 5 illustrating a perspective view and a bottom perspective view of the flip cap 30 of the flip cap type double compartment tube container according to the third example of the present invention will be described.
4 and 5 show only the flip cap 30, but the configuration of the main body 10 is essentially the same as the case of the above-described example, so the description of this is omitted.
The flip cap 30 in the third experimental example according to the present invention illustrated in FIGS. 4 and 5 has a planar shape in which the discharge portion 32 does not protrude and extend upward. Further, a lid mounting portion 31a is formed on the upper surface of the cap body 31, and the lid 34 is fastened to the lid mounting portion 31a.

As illustrated, since the cap partition wall 32c is formed in the discharge part 32, the first discharge hole 32a and the second discharge hole 32b are partitioned and formed. As described above, the lower end portion of the cap partition wall 32c is coupled to the upper partition wall (see reference numeral 17 in FIGS. 1 and 3) of the main body 10, and two protrusions 34a and an annular reamer 34b are formed on the lid 34. Is done.
Further, in order to surely help the ring fixing portion 33 of the cap body 31 to be fixed, a notch groove 33a is formed at a position perpendicular to each other. This is also as described above.
However, since the flip groove is not formed in the lid 34 and the flip groove 31b is formed only at the upper front end portion of the cap body 31, the lid 34 can be easily touched by touching it with a finger and touching it lightly upward. Can be easily opened.

  If the flip cap type double compartment tube container 1 or 1a according to the present invention is used, two dosage forms that cause a chemical reaction, such as an oxidizing agent for hair coloring, a hair coloring agent, and a two-part adhesive resin. When (Formation) is mixed and used, the predetermined mixing ratio can be easily and easily maintained, and the opening and closing operation is very simple and easy. The container is manufactured by extrusion molding with high productivity, and the flip cap, shoulder and neck can be easily joined by heat fusion after injection molding separately, so it has high productivity and easy manufacturing Economical due to the container structure.
