Description

  The present invention relates to the field of personal care packaging, and in particular to a container for preparing a cosmetic mask product to be applied to the skin.

  Various cosmetic masks, sheets and patches are commercially available. Often they are described as beneficial for moisturizing the skin and / or delivering skin care actives. Cosmetic masks usually consist of a woven or non-woven material moistened with a liquid personal care preparation. The mask is flexible so that it can be adjusted to the area of interest (e.g. face or neck) to which it is applied. Mask products are typically sold pre-wetted with liquid products. When applied to the skin, the skin absorbs the liquid product from the moistened mask.

  The main concern of this type of system is that the mask dries before reaching the consumer. Therefore, airtight and liquid-tight packaging are essential. Do you pack a single moistened mask in an air-tight / liquid-tight package (eg packet), or a bundle of moistened masks in an air-tight and liquid-tight reclosable container to an effective degree? It is either. One disadvantage of this type of packaging is that usually only one shape mask is supplied to the container, rather than two or more shape masks used at different parts of the body. It would be convenient for the consumer if the same container of liquid personal care preparation could be used for different shaped masks.

  Another drawback of this type of packaging is that it combines some of the ingredients of the mask with some of the preparations for liquid personal care and that it can not be separated until just before use. is there. For example, assume that the mask is impregnated with a reactive skin care agent. Subsequently, several weeks or months before using the mask, impregnating the impregnated mask with a liquid personal care preparation may adversely affect the efficacy of the active ingredient. This adverse effect may result in loss of effectiveness or loss of effectiveness before the consumer has an opportunity to benefit. Also, possibly liquid skin preparations are subject to a reduction in the stability of the preparation and other adverse effects. In these and similar cases, it would be beneficial if preparations for masks and skin care were separated until just prior to use. On the other hand, if the cosmetic mask is moistened by the consumer immediately before use, it is bothersome and wasteful. These are the cases where the mask can not be wetted in the same sealed container containing the liquid skin care preparation.

  The main object of the present invention is to provide a container system for use with a cosmetic mask, wherein the cosmetic mask can be treated with a liquid personal care preparation just prior to using the mask.

  The object of the present invention is achieved by a container system comprising a container (1) for holding a flowable product (P), a stopper (2) and a strainer (3). When the stopper is attached to the container, the strainer and the stopper define a mask chamber (4) large enough to hold one or more cosmetic masks. The container may be in the form of a bottle having a jar or a neck, both of which have an end capable of receiving a closure for sealing the reservoir and the mask chamber from the environment outside the container system. When the reservoir (1a) of the container is filled with the flowable product (P) and the container is in the standing position, the flowable product in the reservoir may or may not reach the height of the mask chamber, The mask stored in the mask chamber may or may not be moistened. Preferably, when the reservoir of the container is filled and the container is in the standing position, the flowable product in the reservoir has not reached the height of the mask chamber, or otherwise the mask stored in the mask chamber I can not dampen it. The invention comprises a kit comprising a container system as described herein and a set of cosmetic masks not exposed to the flowable product (P).

  Throughout the specification, "comprise" comprises that the element or elements are not automatically limited to those elements specifically recited and may or may not include additional elements. Means Several different features of the embodiments are described below. Certain described features may be used separately from or in combination with other described or implied features. Some of the embodiments may use only one or more of the described features.

  The container system for use with the cosmetic mask comprises a container (1), a bung (2) and a strainer (3) for holding the flowable product (P).

(Container (1) and stopper (2))
Referring to FIGS. 1A, 1B and 2, the container (1) may be in the form of a jar or bottle, in the inside of which is a reservoir (1a) for containing the flowable product (P) It is formed. In the figure, the container is a bottle with a neck (1b). The bottom of the container is shown at (1d) and the top end (or land area) of the neck is shown at (1e). The reservoir is accessed through the opening (1f) of the neck. Generally, the container may be plastic or glass, but plastic is preferred for container handling reasons.

  In the embodiment of FIG. 3, the stopper (2) comprises a side wall (2b, shown as a cylinder) and an upper end (2e). On the inner surface of the cylindrical wall there is a thread (2c). There is also a circumferential lip (2d) on the inner surface of the cylindrical wall above the plug thread. (2a) shows the internal space on the circumferential lip (2d) defined by the upper end (2e) and the cylindrical side wall (2b). In a preferred embodiment of the stopper (2), the height (2h) of the internal space is in the range of about 10 to 30 mm and the diameter (2f) in the range of 25 to 210 mm. Generally, the stopper is molded of plastic.

  The neck (1b) of the container (1) can receive the plug (2) in sealing engagement such that the opening to the reservoir is sealed from the surrounding environment (ie the environment outside the container). For example, the neck and plug may be sealed via threaded engagement, as is well known in the art. The thread (1c) of the neck of the container cooperates with the thread (2c) of the bung. There is a circumferential lip (2d) around the upper end of the plug thread (2c). Optionally, but preferably, an O-ring shaped liner (5) is provided between the circumferential lip (2d) and the flange (3e) of the strainer (3, see below).

(Strainer (3) and mask chamber (4))
Referring to FIGS. 4A and 4B, the strainer (3) comprises a cylindrical wall (3b) having an inner diameter. The tip (3e) of the strainer may be formed as a flange. When the strainer is inserted through the opening (1f) of the neck (1b) of the container (1), the flange (3e) is placed on the upper end (1e) of the container and the rest of the strainer is from the container neck Drooping downwards.

  The tip of the strainer defines an opening (3f), through which the cosmetic mask may be easily inserted into the strainer or removed from the strainer. The inner diameter of this opening may typically be in the range of 25 to 210 mm and preferably corresponds to the inner diameter (2f) of the internal space (2a) of the plug (2). The lower end (3d) of the strainer may be formed as a bowl (as shown) or may be flat or some other shape. The cylindrical wall (3b) and the bottom (3d) of the strainer define the internal space (3a) occupied by the cosmetic mask. The height (3 h) of this internal space may typically be in the range of 25 to 50 mm, but this range is only provided as a guide for typical ones, but it is beyond Good. When inserted into the container (1), the lower end of the strainer may enter the reservoir (1a).

  The strainer (3) may be integrally molded with the container (1), or separately molded as shown, and later attached to the container. The outer diameter of the cylindrical wall (3b) of the strainer is sized to fit inside the opening (1f) of the neck (1b). When the strainer is fully inserted into the neck, the flange (3e) rests on the land area (1e) of the neck. The flanges should not extend laterally beyond the land area at the end of the container. The strainer may be permanently affixed to the neck by welding or an adhesive. The temporary attachment may be a snap fit or a friction fit. Preferably, a friction fit is used. In this case, the outer diameter of the cylindrical wall (3b) of the strainer may be slightly larger than the inner diameter of the opening (1f) of the container neck. With sufficient interference between the cylindrical wall of the strainer and the neck, the strainer will not come out of the container even if the container is upside down. For example, the outer diameter of the cylindrical wall of the strainer may be 0.8 to 1.3 mm larger than the inner diameter of the neck. In order to aid this friction fit, the strainer is preferably made of plastic, and more preferably made of an elastomeric material inert to the contents of the reservoir (1a).

  When the plug (2) is screwed onto the neck (1b) of the container (1), the circumferential lip (2d) comes to compress the flange (3e) of the strainer (3) downwards. Preferably, this contact is sufficient to form a hermetic and liquid seal. However, optionally and preferably, an O-ring shaped liner (5) may be provided between the circumferential lip (2d) and the strainer flange (3e). The liner provides additional sealing integrity. Optionally, a liner may be applied to the circumferential lip of the bung.

  When the plug (2) is installed in the neck (1b), the internal space (2a) of the plug and the internal space (3a) of the strainer (3) are adjacent and from the top of the plug (2e) to the bottom of the strainer (3d) One large space or mask chamber (4) extending is created (see FIG. 1B). The first part (4a) of the mask chamber (4) is located in the container (1) and the second part (4b) of the mask chamber is located in the plug (2) but outside the container. The mask chamber is sealed from the environment outside the container. The mask chamber should be large enough to accommodate at least one cosmetic mask. Preferably, the mask is neatly rolled and / or folded before entering the strainer (see 3, mask (9) in FIG. 8), although this is not required. FIG. 5 shows a full face mask (6). FIG. 6 shows a cosmetic mask (7) for the mouth. FIG. 7 shows a cosmetic mask (8) for the eyes. These figures are for illustration only. Many other types of cosmetic masks may find use in the present invention.

  The cylindrical wall (3b) and bottom (3d) of the strainer (3) have a large number of holes (3g). The holes are such that the flowable product (P) easily flows into the mask chamber and is of sufficient size to flow out of the mask chamber, but the cosmetic mask (5) falls or is pushed into the reservoir (1a) Small enough to prevent. For example, the largest dimension of the hole may be in the range of 2 to 6 mm. The holes need not all be the same size or shape as shown in FIG. 4A.

  Preferably, when the filled container (1) is in the standing position, the reservoir so that the product in the reservoir does not reach the height of the strainer, or the mask stored in the strainer can not be moistened. The height of the flowable product (P) in (1a) is lower than the lower end (3d) of the strainer (see FIG. 1B). If the height of the product is higher than the bottom of the strainer, the cosmetic mask (5) located in the mask chamber (4) can not flow excess product back into the reservoir. By keeping the product height below the strainer, it is possible to wet the mask only when the container is not erected, i.e. when the container is tilted or upside down.

  The container if the strainer (3) is permanently attached to the container (1) (ie by single molding, welding or adhesive), or if the strainer is attached to the container before the container is filled, the container Must be filled through the strainer. In automated filling operations, problems can arise if the holes in the strainer are too small to allow the product to flow rapidly through the strainer. Therefore, in this case, the center of the bottom of the mask chamber is of sufficient size to allow the filling nozzle of the automated filling operation to pass (but at such a size that the cosmetic mask (5) falls off or is packed) There may be one hole (3p, see FIG. 4C). On the other hand, if the strainer (3) is not permanently attached to the container (1), the container may be filled in the usual way and then the mask chamber inserted. In the personal care consumer goods industry, the diameter of the filling nozzle may vary, but the hole (3p) for the filling nozzle may typically be 3 to 12 mm, preferably 5 to 10 mm, for example about 7 mm .

  Preferably, the strainer (3) has a plurality of holes (3g) along its circumferential area and clearly along its height. If there is only one hole around the bottom of the strainer, or if there is not a sufficient number of holes, for example, the product may not penetrate the entire mask if the user takes too little time to upset the container (1) unknown. Also, if there is only one opening around the bottom of the strainer, much of the surplus product in the mask chamber (4) will have to flow through the mask (5), but this process may take time . Impatient users may remove the mask from the mask chamber while the mask is still supersaturated before it has a chance of spilling excess product. On the other hand, if the strainer (3) has a plurality of holes (3g) in its circumferential area and clearly through the length of its height, the mask (5) will be uniformly faster (eg within 30 seconds, Preferably the saturated product saturates within 10 seconds, more preferably within 5 seconds, and the excess product flows out of the mask chamber faster (e.g. within 60 seconds, preferably within 30 seconds, more preferably within 10 seconds).

(how to use)
The user comprises the container system and the dry mask (6) according to the invention. The container (1) is filled with the flowable product (P). The "dry mask" may have been treated with other products but has not been exposed to the same flowable product (P) in the container or has not been treated with the same flowable product (P) Means a mask. If the container (1) is in the standing position, the flowable product (P) in the reservoir (1a) has not reached the height of the mask chamber (4). Optionally, the user may round (as in FIG. 8) and / or fold the mask. The user removes the stopper (2) from the container, places the dry mask (6) in the mask chamber (4) and closes the container (1) again. The user turns the container upside down at least until the flowable product saturates the mask. This may be, for example, as short as 1 to 3 seconds or longer, for example as long as 5 to 10 seconds. The user may return the container to a standing position and then wait at least a few seconds or minutes to be able to flush excess product back into the reservoir. The user opens the stopper and immediately removes the saturated mask, or otherwise waits for a few seconds or minutes so that excess product can drain back into the reservoir, and then removes the mask. The mask is spread and affixed to the skin. Preferably, the mask remains affixed to the user's skin for a recommended time, such as minutes or hours. After this application time, the user removes the mask from the skin and discards the mask. The stopper may be reattached to the container.

  The flowable product (P) can flow through the holes of the strainer when the container (1) is turned upside down and wet the cosmetic mask located in the strainer in a reasonably short time (eg within 30 seconds) It may be any formulation that can be Flowable products which can not pass through the holes even if the container is inverted or can not completely dampen the cosmetic mask in a reasonable time are not suitable for the present invention. Suitable flowable products (P) may contain any active ingredient. Preferably, the flowable product contains at least one skin care active, either in natural or purified form. Natural forms may, for example, be tea leaves or petals. The purified form may be an extract from tea leaf or petals or other organic material.

  The present invention provides a container system having flowable product (P) in reservoir (1a) and a set of dry cosmetic masks not exposed to flowable product (P) as described herein Including a kit comprising Multiple cosmetic masks, such as a bundle of masks, may be packaged in a single container. However, unlike the prior art, these masks are dry, not wet. Preferably, the kit according to the invention comprises a container system as described herein and at least two dry masks (e.g. 2 to 6 dry masks), preferably at least 7 dry masks. More preferably, at least 30 dry masks (i.e., at least 1 monthly supply), or any number of 2 to 60 dry masks. The container system and the set of dry masks may be packaged in a single sheath for retail sale.
