Description

  The present invention relates to a lip pack, and more particularly to a substantially sheet-like lip pack made of a gel composition having a size and shape sufficient to cover the periphery of the lip.

In recent years, a gel-like composition having self-form-retaining properties has been formed into a sheet shape without support such as a non-woven fabric and used as an external preparation.
On the other hand, eye packs or the like in which a medicinal component or a cosmetic component is blended with a sheet-like material composed of such a gel composition are known.
A pack dedicated to the lips is also known, but this lip pack is obtained by applying a plaster made of a water-soluble polymer to a support made of nonwoven fabric, and in addition, a linear break is formed on the portion that hits the mouth during use. Because it was just put in, it was difficult to talk during use, there was a sense of incongruity, and it was not satisfactory.

  Human lips are usually moisturized, and when they dry, the lips can become rough or cracked. Therefore, it has been desired among young women to keep their lips moist, and there has been a desire to develop a lip pack that does not interfere with conversation and does not make you feel that you are using it.

  As a result of intensive studies in order to solve the above problems, the present inventors have found that a simple line is formed at the center of a sheet-like material composed of a gel composition having a size and shape sufficient to cover the periphery of the lips. If a pack is formed on a lip, in which a specific opening is formed and a protruding portion protruding from a specific portion of the periphery of the opening can be locked with the lip Because it is possible to talk during use by forming the opening, and also because it can weaken the holding power of the pack because it can talk, the pack can be locked with the lip formed at the periphery of the opening with the lip It was found that the lips can be held securely and moisturize the lips without hindrance in daily life.

That is, the present invention is a lip pack comprising a gel composition having a size and shape sufficient to cover the periphery of the lips,
(1) a sheet portion formed with a substantially elliptical or substantially oval opening having a major axis substantially equal to the lateral length of the lips at the center;
(2) Out of the peripheral edge of the opening, at least a lower portion and a ridge portion projecting so as to be able to be locked with a lip from both folded portions that are bent upward and continuously bent at both ends of the lower portion. Provide the provided lip pack.

According to another aspect, the present invention provides:
(1) a blister container having a predetermined shape;
(2) A lip pack comprising a gel composition having a size and shape sufficient to cover the periphery of the lips, which is obtained by filling the blister container with a solution of the gel composition and gelling. A sheet portion formed in the center with a substantially elliptical or substantially oval opening having a major axis substantially equal to the lateral length of the lips, and at least a lower portion of the periphery of the opening. A blister container housing lip pack comprising a lip pack that includes a lip portion that protrudes so as to be able to be locked with a lip from both folded portions that are bent upward and continuously bent at both ends of the lower portion. it can.

  The lip pack according to the present invention forms a substantially oval or substantially oval opening having a major axis substantially equal to the lateral length of the lip at the center of the sheet portion, and the periphery of the opening Since the protrusion protrudes from at least the lower part and the both folded parts that are bent upward and continuously bent at both ends of the lower part so as to be locked with the lips, at the center of the seat part, Rather than simply forming a linear cut, a specific opening can be formed to allow conversation during use, and even if an opening is formed to allow such a conversation, a specific protrusion is formed. Since the part can be locked by the corresponding specific part of the lip, it can be ensured without weakening the holding power of the pack, and the lip can be moisturized without trouble in daily life.

In the present invention, the size of the lip pack is not particularly limited, and can be set as appropriate according to the user. For example, for a female adult, the shape of the sheet portion is generally lip-shaped, the length in the longitudinal direction is about 50 to 80 mm, and the length in the short direction is about 20 to 30 mm. preferable. The thickness is 0.5-5 mm, preferably 1-3 mm.
In the lip pack according to the present invention, a substantially oval or substantially oval opening having a major axis substantially equal to the lateral length of the lips is formed in the center of the sheet portion. The size of this opening depends on the size of the mouth of the user, but if the size is 30 to 70 mm in the major axis direction and 5 to 10 mm in the minor axis direction, conversation in use is particularly smooth. It is preferable because it is possible. In addition, it is preferable to set the height of the upper part in the lateral direction to be 3 to 10 mm larger than the lower part because the holding power of the lip pack can be increased.

On the other hand, this opening is disadvantageous for holding the lip pack, but at least the lower part and the both ends of the lower part of the peripheral edge are continuously bent upward and folded from both folded parts. Providing a protruding ridge portion that can be locked enables the lip pack to be securely held. In particular, when the protruding portion protrudes from the entire peripheral portion of the opening so as to be locked with the lips, the lip pack is more reliably held. This ridge may be from the middle rather than from the entire periphery of the opening.
It is preferable that the protruding portion has a protruding height of 2 to 5 mm and a width of about 2 to 4 mm so that the protruding portion can be easily and reliably locked at the lips. In particular, the lip pack is more reliably held when the tip of the ridge portion is along the upper and lower tooth rows.

The lip pack according to the present invention can be obtained by filling a gel composition solution into a blister container having a predetermined shape and gelling.
Although the gel composition which comprises the lip pack of this invention is not specifically limited, What consists of water-soluble polymer is preferable. The water-soluble polymer is not particularly limited as long as it shows a moisture content and a compressive deformation rate described later when the gel-like composition is used.
Moreover, what becomes transparent when it is set as a gel-like composition is preferable. Here, the term “transparent” means a so-called colorless and colorless state called water clear.
“Water-soluble” in the water-soluble polymer means that 1 g of the water-soluble polymer is dissolved in less than about 30 ml of water at around room temperature.

The water-soluble polymer is preferably a natural water-soluble polymer, particularly a polysaccharide. In the case of a natural water-soluble polymer, for example, a gel strength of about 60 to 100 g is suitable. The term “gel strength” as used herein means that a rheometer equipped with a 0.5 inch plunger is used to push the plunger down the surface of the water-soluble polymer gel body by 4 mm at a speed of 6 cm / min. It means the numerical value of force expressed in grams.
Specific examples of the natural water-soluble polymer include carrageenan; locust bean gum; xanthan gum; guar gum; gellan gum; tamarind seed gum;

  Moreover, you may use a synthetic | combination water-soluble polymer, and the average molecular weight in that case is about 1000-200000000, for example. Specific examples include carboxymethylcellulose; sodium carboxymethylcellulose; carboxyvinyl polymer; polyvinyl alcohol; alginic acid; grafted starch; agarose; polyglutamic acid, polyacrylic acid, alginic acid, Ernest gum, and salts and partially neutralized products thereof. .

  The water-soluble polymer can be used as one type or a mixture of two or more types. Two or more natural water-soluble polymers are preferably used in combination, and it is particularly preferable that carrageenan is contained therein.

  Carrageenan is a kind of polysaccharide called galactan which is generally extracted from a seaweed called Irish moss and contains a sulfate group, and has a kappa form, an iota form and a lambda form. Either form may be used, but it is preferred to use a copper and / or iota form, and particularly preferred to include both a copper form and an iota form. The mixing ratio (weight ratio) of carrageenan and other water-soluble polymer is preferably about 1: 0 to 1:10, for example. The ratio (weight ratio) of both the copper type and the iota type is preferably about 1:10 to 10: 1. Particularly preferred is a combination of kappa and / or iota carrageenan: locust bean gum: glucomannan, and the blending ratio (weight ratio) thereof is not particularly limited. It is.

  The water-soluble polymer is contained in an amount of about 0.1 to 10% by weight, preferably 0.3 to 5% by weight, more preferably about 0.5 to 3% by weight, based on the entire gel composition. The water-soluble polymer is preferably edible. Here, “edible” means that eating and drinking is permitted by a law that regulates food and the like.

The gel composition constituting the lip pack of the present invention is obtained by dissolving the above water-soluble polymer in water and gelling, and the water content thereof is about 30 to 95%, preferably about 40 to 85%. More preferably, it is about 50 to 80%. When the moisture content is lower than 30%, not only the compression deformation rate described later can be obtained, but also the water retention is remarkably lowered, and the skin surface is easily peeled off, and the skin surface is dried or rashed. There are inconveniences. In addition, when the moisture content exceeds 95%, the compressive deformation rate is remarkably lowered, the gel composition becomes brittle, and it cannot be sufficiently used in use. It becomes worse and easily peels off the skin.
The gel composition constituting the lip pack of the present invention has a compression deformation rate of 65 to 99%, preferably 70 to 95%, more preferably about 75 to 90%. When the compression deformation rate of the gel composition is within this range, the tensile strength and the compatibility with the undulations and wrinkles of the sticking surface are excellent.

The "compression deformation rate" here is the maximum until partial destruction of the gel structure occurs when the gel composition is compressed at a predetermined speed using a plunger that can be pressed at a constant speed. The deformation rate is expressed as a percentage. When measuring the compressive deformation rate, the gel composition is a flat sample having a predetermined thickness, for example, a thickness of about 1 to 10 mm, preferably a thickness of about 2 to 4 mm. The plunger is substantially cylindrical and has a predetermined cross-sectional area, for example, a cross-sectional area of about 0.1 to ² cm ² , preferably about 0.5 cm ^2. It is installed. As the compression test apparatus, for example, a texture meter that measures food texture, a rheometer that measures viscoelasticity, or the like can be used. The speed of the plunger at the time of measurement is about 0.01 to 0.1 mm / second, preferably about 0.05 mm / second.

The gel composition can be gelled by dissolving a water-soluble polymer in warm water of about 60 to 90 ° C. and allowing to cool to about 20 to 40 ° C. The gel composition includes medicinal ingredients (eg, licorice extract, urea, vitamin B group, vitamin C, vitamin E, popidone iodine, etc.) or cosmetic ingredients (eg, trehalose, vegetable collagen, trimethylglycine, aloe, Honey etc.) may be added, or additives usually used in the field of medicine or cosmetics, such as preservatives, bactericides, fragrances, colorants, antioxidants, etc. may be added. Furthermore, you may add the aroma oil etc. which are used for aromatherapy.
The medicinal component may be used as a granular material wrapped with a polymer film, or may be impregnated and supported on a porous polymeric granular material.

As the aroma oil, essential oil components (essential oils) generally used for aromatherapy can be used as they are. Examples of the essential oil component include those described in Wonder Cellar “84 essential oil components for aromatherapy” and Fragrance Journal. Specifically, Anise, Angelica, Benzo, Immortelle, Chamomile, Garlic, Cardamom, Galvanam, Caraway, Carrot Seed, Guayac Wood, Grapefruit, Cybless, Cedarwood, Star Anise, Sage, Geranium, Celery, Thyme, Tarragon, Terpin , Frankincense, violet, pine, parsley, fennel, black pepper, bodaiju flower, lemon, lemongrass, rosemary, laurel, shimotsukegiku, shimotsueso, cornflower, almond, arnica, fennel, enishida, watercress, gentian, ginger, plum Pear, seaweed, dandelion, chimo, chorei, capsicum, green rose, mint, ash, bullock, melissa, peach, mistletoe, eucalyptus, yokuinin, Vendor, it includes extracts from such forsythia.
