Description

Specification container and its application

The present invention relates to a packaging container for two kinds of materials with different properties which are mixed together only when they are used. In particular, it is used to achieve proportional mixing of one-way packaging, and it can also be used for normal pressure foaming of mousse products. Background technique

In daily life, due to the chemical properties of certain substances or other reasons, it is necessary to separate the product into two dosage forms and mix the two dosages together before use. Common products are certain hair dyes and certain binders.

For two-type hair dyes, the two dosages are usually squeezed on the comb and then combed on the hair. In this way, the problem of the quantitative proportion of the two doses of hair dye is obviously difficult to be accurately determined by visual inspection; there is also the problem of mixing, because the mixing is actually performed on the hair, and it is difficult to ensure a good effect. It is more troublesome to mix in the device M.

In order to solve the above problems, the inventor has invented a ^{/ Λ} dual-cavity mixed packaging container 〃, whose Chinese patent application number is 9 3 2 G 697 6.2. The double-cavity mixed packaging container includes a container body, an inner plug and a container lid. The container body is formed with two cavities, and the inner plug is provided with some small holes.

When the dual-cavity mixed packaging container is used, the cavity (or pipe) between the inner plug and the nozzle is actually used as the mixing cavity.

The above dual-cavity mixed packaging container has the following problems: first, it has an inner plug, which is more complicated to assemble; second, if it is used for hair dye, it is difficult to clean the mixing cavity, which will cause pollution to the dual-cavity container. Disclosure of invention

The invention proposes a double-chamber container with a simple structure, injecting an inner plug in the container body at one time, thereby solving the problem of assembly.

In addition, the present invention also proposes a double-chamber bag, a double-chamber bag made of soft glue, especially a composite film, which can be produced by hot pressing, which has the advantages of simplicity and ease of manufacture.

For some dangerous products, the present invention solves the problem by using one of two accessories: One: The container cap is designed to be composed of a cap tube and a cap plug, the cap plug functions as a container seal, and the cap tube serves as a mixing chamber. If necessary, the cover tube can be removed and washed.

τ this Second: The proportional liquid pump is installed on the container cover, that is, two sets of pumps are used to share a mixing nozzle, so that the nozzle can be easily removed and washed.

In fact, the proportional liquid pump can be designed so that the cross-sectional areas of the pistons of the two sets of pumps become a certain ratio, so as to obtain the required mixing ratio.

The dual-cavity container can also be designed so that the cross-sectional areas of the two cavities are in a certain ratio. When the two cavities are pressed at the same length at the same time, the required mixing ratio can be obtained.

Therefore, the dual-cavity container provided by the present invention is not only simple in structure and easy to manufacture, but also can obtain a certain mixture according to the required ratio, and the mixing accessories are easy to clean. Brief description of the drawings

Referring to FIG. 2, the manufacturing method of the container body of the container shown in the figure is the same as the first embodiment.

The container lid consists of a lid tube (5) and a lid plug (6). The cover tube (5) can cooperate with the nozzle part (3), The cap (6) can be inserted into the cap tube (5), and the container is sealed. When in use, the cap plug (6) is lifted out, and the channel of the cap tube (5) becomes a mixing chamber, which can be removed and washed when needed.

Example three

Referring to FIG. 3, two single-cavity containers (21) are prepared in advance by using the method of Embodiment 1 or a bottle blower, and then the two containers are bonded together to obtain a dual-cavity container;

Referring to FIG. 4, containers of different sizes are prepared by using the method of the third embodiment, and then a smaller container (22) is sleeved into a larger container (23) to obtain a double-chamber container.

The double-chamber container shown in Figures 1 to 4, the cross-sectional area of the double-chamber can be made to the required ratio.

Embodiment 4

Referring to FIG. 5, the hot stamping die is designed, and its pressing line is shown by the thick black line in FIG. 5. Overlap the two (soft rubber or) composite films and heat press with a hot stamping die, and the crimping wire is welded to the two composite films to form a hot-pressing connection (32), and surround the double-chamber bag body (31) and the bag mouth. (33)

When in use, use a hard object to peel off the hot-pressed wiring from the bag mouth, and then the materials in the double cavity can be pressed out from the bag mouth. For products that are used many times, it can be used with a spring jacket. After each use, use the spring clamp to clamp the proper position of the nozzle. ¹

The cross-sectional area of the two cavities of the double cavity bag can also be designed to meet the required proportional relationship.

The use of one or more composite films can easily make a double cavity bag, except that the pressing line of the hot stamping die needs to be changed accordingly.

Example 5

For a double-lumen container with a small diameter or a small cross-sectional area, it is convenient to squeeze the double-lumen from the end of the tube to the nozzle with a finger, and obtain a roughly accurate proportion. ,

For a double-lumen hose or a double-lumen bag with a larger diameter or a larger cross-sectional area, it may be difficult to push with one finger. Therefore, the present invention designs a quantitative push plate for use when needed.

Referring to FIG. 6, the quantitative pushing plate is a thin plate (8), and a long slit (υ) is formed on the plate, and its size is compatible with the double-chamber container flattened along the compartment (2). Protrude into the slit (9), when the sheet (8) is pushed in the direction of the nozzle (3), the material of equal length can be extruded in the double cavity, and its volume is proportional to the cross-sectional area of the double cavity, So as to achieve the purpose of mixing the contents of the two chambers in proportion.

For harder dual-chamber containers, it is generally not possible to squeeze the material by squeezing the container body. In this case, a proportional liquid pump can be used. For the proportional liquid pump, refer to the Chinese patent application) 3215052.7. The proportional liquid pump disclosed in this patent application consists of two guide pipes (10) and two sets of piston pumps. (II), the two outlet pipes (1 连接 are connected in series and connected with a mixing nozzle (13) in sequence. When the nozzle (13) is pressed, two sets of piston pumps (11) act simultaneously and reciprocate the same stroke. The output of the two sets of piston pumps (1 1) is proportional to the cross-sectional area of the two pistons, so it can be used to achieve the required mixing ratio.

The proportional liquid pump is installed on the container lid (4), and by pressing the spray head (1 3), the purpose of mixing the materials in the double cavity and spraying out can be achieved.

The mixing nozzle (1 3) can be easily removed and washed. Industrial applicability

The double-chamber container can obviously be used for one-type packaging, as long as the two materials are separately filled into each cavity and sealed. Such as hair dye, adhesive, etc., can be applied. In addition, it can also be used to achieve normal pressure foaming of mousse products.

Mousse is the Chinese transliteration of H0US S E, which means foam. It is mostly used in cosmetics.

Conventional mousses are packed in pressure tanks, filled with compressible gas, and when the valve is opened, the gas pressure is used to expand and expand to foam. Filling with propane and butane gas may cause fire or explosion.

Using a dual-chamber container, using some mousse raw materials, containing unneutralized acid groups, and mixing with other materials, made into A cavity in one cavity; the other cavity was added with carbonate or hydrogen carbonate equivalent to acid The salt and other ingredients are agent B; the human and agent B materials are divided into two material cavities of the double cavity container. When used, the two equivalents of A and B are mixed in an equal amount to emit CO and foam. The acid hydrolysis reaction is as follows:

[CO3]-+ 2 [H] ⁺ ■ → C0 _t + H _s 0

[HCOj]-+ [H ― C0 _t + HO

It is one aspect of the present invention to use a dual-chamber container to make a mousse product by using a controlled acid hydrolysis reaction to produce (: 0 ₄ foaming).

The acid or acid used must be stronger than carbonic acid, including inorganic and organic acids. In use, it must first comply with the relevant regulations and safety regulations formulated by the department to which the product belongs; second, it must be consistent with the purpose of use of the product or have no major impact.

The use in cosmetics is restricted by the relevant regulations of the cosmetics industry. Generally used in cosmetics are: hydrochloric acid, phosphoric acid, acetic acid, propionic acid, glycolic acid, lactic acid, citric acid, succinic acid, tartaric acid, thioglycolic acid, peroxyacetic acid, certain acidic surfactants and acidic resins.

Suitable carbonates, bicarbonates are mainly potassium, sodium, calcium, magnesium, and ammonium salts; and organic amine salts: mainly monoethanolamine, diethanolamine, triethanolamine, isopropanolamine, and aminomethylpropanol Bicarbonates

It should be noted that the foam density of co ₃ foam used in mousse products is higher than that of conventional mousse, but it does not affect the use. Considering the factors of safety, environmental protection and cost, the dual-cavity container is used for co _A Foaming into mousse products has its practical significance.
