Description

Small mask pack pouch containing dry biocellulose sheet in compressed form {Mini pouch containing dry biocellulose sheet with compressed form}

The present invention discloses a small mask pack pouch comprising a dried biocellulose sheet in a compressed form.

Biocellulose (Microbial Cellulose/Microfibrous Cellulose) is a polymer material produced by cultivation of strains, and fibers having a size of 20 to 50 nm with beta-1,4-glucan as a primary structure form a three-dimensional network structure. Unlike plant cellulose, the biocellulose is produced in a pure cellulose state without any lignin or hemicellulose, and is industrially developed for various uses.

Because of this structure, it has properties such as wettability, absorbency, high strength, and high elasticity, and has been applied and developed in various industries such as cosmetics, medical products, dietary fiber, acoustics, and industrial use. It is also used in medical pharmaceutical fields such as artificial skin, wound healing agents, artificial joints, artificial muscles, artificial blood vessels, and bioactive agents.

In particular, biocellulose is widely used as a mask pack in the cosmetic field.

Unlike non-woven masks or gel masks, the biocellulose mask pack is a fermented mask with an ultra-fine net structure, and is a third-generation mask pack with a structure similar to skin protein.

Currently commercially available biocellulose mask packs produce biocellulose by fermenting fermented broths such as coconut, bokbunja, and tangerine by bacteria, and then washing and sterilizing them to produce a wet-type mask pack. This bio-cellulose mask pack has the advantage that it can be used for sensitive skin due to its natural material, and it is perfectly adhered to the skin to provide sufficient moisture and supply of active ingredients. However, as it is manufactured in a wet state, it is easily contaminated by mold or bacteria, and thus a high concentration of preservative or gamma ray treatment is required.

In the case of the existing wet-type biocellulose mask pack, it is swelled to moisture or a cosmetic solution and is loosely lumped and sealed inside a hemispherical plastic container and sold. The swollen biocellulose mask pack can be lumped, but it occupies a relatively large volume, so the size of the container is bound to increase.

Korean Patent Publication No. 10-2018-0076170 discloses a method of applying chlorine dioxide (ClO ₂ ) to bio-cellulose and treating it with plasma so that long-term storage without the use of preservatives is possible. However, the chlorine dioxide is originally a bleaching agent or sterilizing and disinfecting agent, which is a substance that may cause side effects such as skin irritation, and plasma treatment also requires high cost.

In addition, Korean Patent Registration No. 10-1805171 discloses a content of manufacturing a dry biocellulose sheet, storing it in a container as shown in FIG. 3, and injecting a cosmetic emulsion to manufacture a mask sheet. When stored in a large container as shown in FIG. 3, there is a problem of an increase in cost and large volume due to the container manufacturing. In addition, the existing wet-type problem, that is, the problem of generating mold or bacteria still remains.

Republic of Korea Patent Publication No. 10-2018-0076170 (2018.07.05), Method for sterilizing biocellulose for mask pack using plasma Korean Patent Registration No. 10-1805171 (2017.11.29), Bio-cellulose paper and its manufacturing method

The Applicant has confirmed that the dried biocellulose is properly dried to have a specific moisture content, and is easily compressed into a small size when it has a specific thickness or parameter, and that the compressed state is maintained for a long period of time. In addition, it was confirmed that when a certain amount of water was added in the compressed state, it could be easily restored to its original state and used as a mask sheet.

Accordingly, the applicant of the present invention manufactures a mask sheet using dry biocellulose instead of wet biocellulose that does not require preservatives, but includes dry biocellulose in a form compressed into a small size so that it can be accommodated in a small size pouch for convenience of portability. A small mask pack pouch was prepared.

In particular, a small mask pack pouch including dry biocellulose that can be easily compressed into a small size so as to be accommodated in a small size pouch and is restored to a state that can be used in a short time when water is added was manufactured.

In addition, a mask pack pouch that allows users to participate in the process of directly manufacturing the pack was manufactured by performing the process of adding and leaving water for swelling, like conventional cup noodles, to induce fun and interest to users.

Accordingly, an object of the present invention is to provide a mask pack pouch in which a dry biocellulose sheet is embedded.

In addition, another object of the present invention is to provide a method of using the mask pack pouch and a disposable skin care kit using the same.

In order to achieve the above object, the present invention provides a small mask pack pouch including a dry biocellulose sheet in a compressed form in the inner space of the small pouch.

The moisture content of the dried biocellulose sheet is 1.5% by weight or more and less than 5% by weight.

In addition, the dry biocellulose sheet has a swelling degree of 85 to 95% by weight after 3 minutes.

In addition, the present invention provides a disposable skin care kit including the small mask pack pouch.

In addition, the present invention provides a method of using a mask pack pouch, which is used 3 minutes after adding water to the small mask pack pouch.

The small mask pack pouch in which the dry biocellulose sheet according to the present invention is embedded can eliminate the use of preservatives harmful to the skin, and has the advantage of being able to be stored in a pouch of a small volume.

These small mask pack pouches are swelled through the process of adding and leaving water and converted into a wet biocellulose sheet that can be used and attached directly to the skin, allowing the user to actively participate in the pack manufacturing and to be fresh ( fresh), it can cause fun and interest.

3 is a view showing a container in which a biocellulose sheet is embedded according to the prior art.

The present invention discloses a small mask pack pouch comprising a compressed 100% dry biocellulose sheet.

The biocellulose sheet of the present specification refers to a sheet manufactured in a shape that can be attached to the body by cutting it according to a purpose, such as a face shape or a partial patch shape.

The dry biocellulose sheet has the property of swelling and changing to a gel state when moisture is added. The microstructure of the dried biocellulose sheet may include a plurality of spaces in which the biocellulose forms a three-dimensional network structure to contain moisture or active ingredients. This may contain more moisture or active ingredients due to a denser fiber structure and a high specific surface area compared to the conventional nonwoven fabric or wet biocellulose sheet used as a mask. The swollen biocellulose sheet can be used in a wet state in close contact with the skin.

In addition, the dry biocellulose sheet has a low moisture content, so it is easy to store at room temperature and is significantly longer than other sheets during the distribution period.

The small-sized mask pack pouch according to the present invention has been prepared as a small-sized mask pack pouch that can actively utilize the advantages of dry biocellulose, such as preservative-free, excellent moisture and active ingredient absorption, room temperature storage, and long shelf life.

1 is a perspective view showing a small mask pack pouch in which a biocellulose sheet is embedded according to the present invention.

In the small mask pack pouch 20 of FIG. 1, a dried biocellulose sheet 24 compressed inside the sealed small pouch 22 is embedded. In FIG. 1 below, for convenience, it is shown as a flat cylinder (or coin type), but the biocellulose sheet aggregated after compression may have a hexahedral shape, a spherical shape, an elliptical shape, or an irregular shape.

The compressed dry biocellulose sheet 24 should be converted into a wet sheet after swelling, so that it adheres well to the skin and does not cause damage such as tearing during use.To this end, the compressed dry biocellulose sheet 24 should be at least 1.5 mm. It should be 2.7mm thick and weigh from 1g to 3g. If the thickness is too thin below the above range, the biocellulose sheet adheres too much after swelling, making it difficult to unfold when used.If the thickness is too thick, the sheet becomes too thick and there is a problem that adhesion decreases when attached to the skin. do.

In order to stably put a sheet of such thickness and weight into the small pouch 22 in a compressed form, the compressed dry biocellulose sheet 24 is preferably spherical or elliptical, and the diameter is 2.5 to 4 cm. It is more preferable to be.

On the other hand, the small pouch 22 is made of a film material such as PSP, EPS (Expanded Polystyrene), PP, etc., and is sealed through thermal bonding after inserting a biocellulose sheet with one side open. There is a cutting line about the boundary of the small pouch, and this part is cut or split to be used.

The small pouch 22 has a size of 3.0 to 7.0 cm in width and 3.5 to 7.5 cm in length.

In particular, the compressed dry biocellulose sheet 24 according to the present invention is converted into a wet biocellulose sheet that can be used and attached directly to the skin by swelling through the process of adding water and leaving the same as in the conventional cup noodle manufacturing process. , It is possible to induce freshness, fun, and interest by allowing users to directly participate in pack manufacturing.

That is, the compressed dry biocellulose sheet 24 must be able to be accommodated in the small pouch 22, and the compressed state must be maintained for a long period of time, and when a certain amount of water is added in the compressed state, it is easily restored to its original state. It should be easy to use because it adheres well to the skin. These functions and effects can be further increased through the satisfaction of certain parameters of the dry biocellulose sheet.

In the present invention, parameters of the moisture content and swelling degree are selected, and these parameters are limited.

The moisture content refers to the content of moisture remaining in the sheet. As the moisture content is lower, there is no occurrence of bacteria or viruses, and thus, a moisture content rate of less than a predetermined range may be regarded as a value indicating a dried state at a level in which no preservative is required. On the other hand, as the moisture content in the sheet decreases, the volume of the sheet decreases. With this concept, in the present invention, it is possible to manufacture and maintain the compressed form by controlling the moisture content of the compressed dry biocellulose sheet 24. In addition, the moisture content is adjusted for quick conversion when converting to a wet sheet after adding water later.

The moisture content according to the present invention is calculated by Equation 1 below.

[Equation 1]

Moisture content (% by weight) = (a-b) / a x 100

(Wherein, a is the weight of the compressed dry biocellulose sheet to be put into the small pouch, d is the weight measured after completely removing moisture by leaving the compressed dry biocellulose sheet at a drying oven temperature of 100°C for 24 hours And the moisture content is an average value using 50 samples.)

According to Equation 1 above, the compressed dry biocellulose sheet 24 according to the present invention has a moisture content of less than 5% by weight and less than 4.5% by weight, and at least 1.5% by weight for use after swelling in water, It has a value of 2% by weight or more. If the value exceeds the above range, the compressed dry biocellulose sheet 24 expands due to moisture content, making it difficult to accommodate in the small pouch 22 and increasing bacteria due to moisture may be a concern. On the contrary, if it is less than the above range, a lot of water is required for swelling, and a long time of about 7 minutes or more is required for use after swelling in water, but there is a risk of contamination before use of the wet sheet.

The compressed dry biocellulose sheet 24 is stored in a container for several days to several months to be distributed, sold, and used, and no matter how well the storage container is sealed, it may be swollen by the input moisture. The swollen biocellulose sheet expands in volume, and bacteria can be generated or proliferated by moisture. This range of moisture content is a number that can compensate for unwanted moisture input during use or storage.

After adding water to the compressed dry biocellulose sheet 24, the sheet is left to stand for 3 minutes to cause swelling of the sheet. At this time, it must have a certain degree of moisture content (ie, moisture content) for use, and this parameter can be found by measuring the swelling degree after 3 minutes. The degree of swelling can be measured by changing the weight.

After 3 minutes, the swelling rate is calculated as shown in Equation 2 below.

[Equation 2]

Swelling degree (% by weight) after 3 minutes = (d-c) / c x 100

(Wherein, c is the weight of the compressed dry biocellulose sheet added to the small pouch, d is the weight of the sheet measured after 3 minutes after adding 20 ml of water to the compressed dry biocellulose sheet, and the swelling degree is 50 This is the average value using three samples.)

The swelling degree of the compressed dry biocellulose sheet 24 according to Equation 2 after 3 minutes is 85% by weight or more, 85 to 95% by weight, 86 to 94% by weight, and 89 to 92% by weight. If the degree of swelling is less than the above range, it means that the compressed dry biocellulose sheet 24 does not swell sufficiently, and if it exceeds the above range, there is a foreign body sensation due to weight when it is attached to the skin, especially the face, and the active ingredient may flow down. Therefore, delivery of the active ingredient may not be sufficient.

On the other hand, the compressed dried biocellulose sheet 24 is stored in a container in a dry state and taken out from the container when used for use. The compressed dry biocellulose sheet 24 is manufactured in a compressed form to be put into the small pouch 22, and damage may be caused by an external force for such compression. In addition, for the purpose of promoting swelling for use, a mixing means such as a hand or a stick is used to exert a physical force such as vertical or horizontal repetitive movement after contact. In addition, the swollen wet sheet is well stretched and adhered to the face, and a process of manual manipulation is performed so that the eyes and mouth can be seated in the perforated area. At this time, the wet sheet may be damaged or torn along the perforated portion or the outer circumferential surface by the applied force. In order to prevent this, the compressed dry biocellulose sheet 24 has an appropriate level of tensile strength and elongation in dry and wet conditions.

The manufacture of the mask pack pouch 20 in which the compressed dry biocellulose sheet 24 having the above parameters is accommodated is not particularly limited in the present invention, and may be achieved by a known method of manufacturing a sheet.

The biocellulose sheet, which is a raw material of the biocellulose sheet, is obtained by fermenting a natural material, and can be produced directly or purchased and used commercially. In particular, in order to reduce costs, a residue remaining after manufacturing a mask sheet made of only biocellulose may be used.

The raw material of the bio-cellulose is not particularly limited in the present invention, and any known material that is harmless to the human body, especially used in cosmetics or medical fields without skin irritation, may be used. For example, it may be coconut pulp, watermelon, sugar cane, tropical fruit, or a pulverized product thereof, and preferably coconut pulp may be used.

As an example, the production of bio-cellulose using coconut flesh is as follows.

First, after adding microorganisms to the coconut flesh, opaque gel is obtained by static mixing culture or stirring mixing culture at 20-40°C for 5-10 days.

The microorganisms for use either or, the production efficiency is selected from acetonitrile bakteo (Acetobacter), A rayijo Away (Rhizobium) genus Agrobacterium bakteo (Agrobacterium), program also Manas in (Pseudomanas), buy Sina in (Sarcina) It is also possible to mix and cultivate several kinds of microorganisms.

Next, the opaque gel is washed and dried to form a sheet.

After the dried biocellulose sheet is cut, it is put into the small pouch 22 in the form of a lump by performing a compression process of pressing at a predetermined pressure using a hand or a mechanical device.

Preferably, the pressing process is performed by inserting a dried biocellulose sheet into a cylindrical mold and then pushing a compression mechanism, or by inserting a dried biocellulose sheet into a spherical mold and pressing the mold. It is possible. At this time, the dried biocellulose sheet is compressed and lumped by a pressing mechanism, and moisture remaining after the drying process is further removed, thereby making it possible to produce a moisture content of less than 5%. The pressing process can be performed at room temperature, and the temperature inside the mold is adjusted to 30 to 45°C in order to more easily control the moisture content. If the temperature inside the cylinder is too high, bio-cellulose sticks together and cannot be used. On the contrary, when the temperature is low, a high pressure must be applied to remove moisture, so there is a concern that damage such as tearing of the sheet may occur. At this time, the pressing time is performed briefly for 10 seconds to 2 minutes, preferably 20 seconds to 1 minute 30 seconds.

Next, after putting the compressed dry biocellulose sheet 24 in the compressed form into the small pouch 22, the opening portion is sealed to manufacture the small mask pack pouch 20.

At this time, if necessary, a gamma treatment process is performed on the small mask pack pouch 20 for sterilization.

The small mask pack pouch 20 as described above may be applied to a disposable skin care kit.

The disposable skin care kit may include only the small mask pack pouch 20 or a separate liquid or powder pouch having an active active ingredient, and may further include a quantity of water. At this time, water is excluded so that it can be properly controlled by the user, so that a kit can be manufactured.

The compact mask pack pouch 20 in which the compressed dry biocellulose sheet 24 according to the present invention is embedded can exclude the use of preservatives harmful to the skin by using the dry biocellulose sheet, and is stored in a small volume pouch There are possible advantages to this.

This small mask pack pouch 20 is swelled through a process of adding and leaving water and converted into a wet sheet that can be directly used and attached to the skin, so that the user is actively participating in the pack manufacturing and is fresh. It can induce (fresh), fun, and interest.

Looking at the table, it can be seen that the dried biocellulose sheets prepared in Examples 1 and 2 and Comparative Examples 1 and 2 have a water content of less than 4.5% and a swelling degree of 91 to 92%.

In addition, even if the moisture content is appropriate, it can be seen that in the case of the comparative example 2 sheet, the thickness of the sheet is thick and the volume of the sheet is increased, so that it is not easy to accommodate the small pouch.

As in Comparative Example 3 and Comparative Example 5, in the case of the sheet having a very low moisture content, the coin diameter was low, so that it was easy to be stored, but it can be seen that the production efficiency decreased due to the long pressing process time due to the low moisture content. In addition, due to low swelling, it is difficult to adhere to the skin or damage to the sheet occurred. In addition, in the case of the sheet of Comparative Example 4, the moisture content was high, so that the storage was not easy, but the adhesion to the skin was excellent due to the proper swelling.
