Patent Description:
Recently, interest in the cosmetics industry is running high, and it relates to the aspects that distribution networks, such as online channels, are diversified and sales performance of domestic cosmetic brands has been increased greatly in China, Asian nations, and other countries due to the Korean wave. Such emergence of the domestic cosmetics industry is called K-beauty, and is in the limelight as one of main market flows.

In connection with cosmetic technology, cosmetic containers and cosmetic manufacturing methods with improved functionality and usability together with cosmetic composition or formula including natural ingredients or functional ingredients have been developed continuously.

The cosmetic containers are containers to store a cosmetic substance or makeup tools, such as puffs, therein, and forms and structures of the cosmetic containers are as varied as kinds of cosmetics.

For example, there is a stick type cosmetic container. The stick type cosmetic container generally includes an inner container, which stores a cosmetic substance of a solid state or a semisolid state, such as lipsticks, lip glosses, sunblock sticks, and others, and an outer container for protecting the inner container storing the cosmetic substance therein.

However, in such a stick type cosmetic container, a lot of the cosmetic substance is not used and is wasted. Moreover, the conventional stick type cosmetic container has inconvenience in that a user must dig out the remainder with a cotton swab or freeze the remainder when removing the cosmetic contents.

Referring to <FIG>, a cosmetic substance <NUM> is put in a cosmetic holder <NUM>. Here, the contents located in an inner part of the cosmetic holder <NUM> is called a residual quantity <NUM>, and the residual quantity cannot be used finally.

In order to solve such a problem, several techniques have been proposed, but there is still a structural difficulty in using the entire amount of the cosmetic substance. Additionally, a stick type cosmetic container which is simple and convenient in structure to enhance productivity and usability is not yet developed.

Here, <FIG> corresponds to <FIG>, <FIG> corresponds to <FIG> and <FIG>, and <FIG> corresponds to <FIG> and <FIG>. Furthermore, <FIG> respectively show the same operational processes as <FIG>.

In the meantime, the stick type cosmetic container <NUM> according to the first preferred embodiment of the present invention (see <FIG>) and the stick type cosmetic container <NUM> according to the second preferred embodiment of the present invention (see <FIG>) are identical or similar to each other in function or configuration except the shape of an inner container upper part <NUM>, the shape of the upper surface of a first inner container <NUM>, and the shape of an upper part of a second inner container <NUM>. Therefore, hereinafter, without discrimination of the embodiments, the configuration and the operational process of the stick type cosmetic container <NUM> according to the present invention will be described, and different parts in the embodiments will be described separately.

As shown in the drawings, the stick type cosmetic container <NUM> according to the embodiment of the present invention is a container capable of exhausting the residual quantity of a cosmetic substance.

The stick type cosmetic container <NUM> includes: a handle <NUM> for controlling ascent and descent of the cosmetic substance; an inner container <NUM> joined between an outer end part <NUM> and an inner end part <NUM> of the handle <NUM> and having a first hollow part <NUM> formed therein; an inner member <NUM> joined between the inner container <NUM> and the inner end part <NUM> of the handle <NUM> to be fixed in its location; a holder <NUM> elevatable from the inside of the inner container <NUM> along a screw thread part <NUM> formed on the inner end part <NUM> of the handle; and an outer container <NUM> for covering the inner container <NUM>.

Here, the holder <NUM> includes a first inner holder <NUM> and the second inner holder <NUM>; and a second hollow part <NUM> disposed in the first inner holder <NUM> and the second inner holder <NUM> to accommodate the residual quantity of the cosmetic substance therein.

When the cosmetic substance in the first hollow part <NUM> is exhausted, the first inner holder <NUM> ascends from the second inner holder <NUM> so that the residual quantity of the cosmetic substance in the second hollow part <NUM> is exposed to the outside.

In more detail, the handle <NUM> includes the outer end part <NUM> and the inner end part <NUM>. The inner end part <NUM> of the handle has the screw thread part <NUM> in order to lift up and down the holder <NUM> out of and into the inner container <NUM> depending on rotation of the handle <NUM>, which will be described later.

The inner container <NUM> is a cylindrical member, and a lower end part <NUM> of the inner container <NUM> is inserted between the outer end part <NUM> and the inner end part <NUM> of the handle <NUM> to be joined in a relatively rotatable manner. The inner container <NUM> further includes the upper part <NUM> disposed at the upper side thereof.

The inner container <NUM> has the first hollow part <NUM> disposed therein, and the first hollow part <NUM> is a space fixed at the holder <NUM> to store the cosmetic substance of a solid state or a semisolid state therein, and serves as a space for lifting up and down the holder <NUM>.

The inner container <NUM> has a stepped jaw <NUM> disposed at the central portion of the inner face thereof. An upper end of a second inner holder <NUM> is located at an upper portion of the inner container where the stepped jaw <NUM> is formed, and the location of the upper end of the second inner holder <NUM> may be varied according to stroke. In the meantime, a protrusion part may be formed at an outer face of a lower end of the second inner holder <NUM> in a radial direction. If the upper end of the second inner holder <NUM> is at the maximum stroke, namely, in case of the normal operational state (use state) of <FIG> and in case of the final use state (residual quantity use state) of <FIG>, the protrusion part of the lower end of the second inner holder <NUM> may be combined with the stepped jaw <NUM> of the inner container <NUM>.

The inner member <NUM> is a cylindrical member, and is joined between the inner container <NUM> and the inner end part <NUM> of the handle to be fixed. An inner member upper surface part <NUM> is disposed at the upper side of the inner member <NUM> in a flange form, and an inner member lower side protrusion part <NUM> is disposed at the lower side of the inner member <NUM> to protrude outwardly in an outer circumferential direction.

The holder <NUM> includes a first inner holder <NUM> and the second inner holder <NUM>.

The first inner holder <NUM> and the second inner holder <NUM> may be operated like a single member in the normal use state, namely, in the non-use state which is the initial operational state (locked state) and in the normal use state (use state).

After that, if the cosmetic substance is exhausted, namely, if the cosmetic substance in the first hollow part <NUM> is exhausted, when the first inner holder <NUM> is lifted upwards from the second inner holder <NUM> by external force, the residual quantity of the cosmetic substance existing in the second hollow part <NUM> disposed inside the first inner holder <NUM> and the second inner holder <NUM> is exposed to the outside.

The first inner holder <NUM> includes a first inner holder outer face protrusion part <NUM> disposed at the outer face of the upper end thereof, a first inner holder intermediate protrusion part <NUM> disposed at the central part thereof, and a first inner holder lower face protrusion part <NUM> disposed at the outer face of the lower end thereof in the outer circumferential direction.

The second inner holder <NUM> includes a second inner holder upper end part <NUM> disposed at the upper side thereof, and the second inner holder upper end part <NUM> may be an inclined part or an undercut. The second inner holder upper end part <NUM> comes into contact with the inner container upper part <NUM> when the holder <NUM> is lifted up.

The second inner holder <NUM> includes a second inner holder inner face concave part <NUM> formed inwardly from the lower part of the second inner holder <NUM>.

Therefore, the first inner holder outer face protrusion part <NUM> and the second inner holder inner face concave part <NUM> may be combined with each other. Differently from the above embodiment, the first inner holder <NUM> may have a concave part and the second inner holder <NUM> may have a protrusion part such that the concave part and the protrusion part are combined with each other.

As described above, the first inner holder intermediate protrusion part <NUM> is disposed at the central part of the first inner holder <NUM>, and the inner member upper face part <NUM> is disposed at the upper side of the inner member <NUM>. The inner member upper face part <NUM> may be a stopper getting in contact with the first inner holder intermediate protrusion part <NUM> (see <FIG> and <FIG>).

When the first inner holder intermediate protrusion part <NUM> passes through the inner member upper face part <NUM> by the external force, the combination between the first inner holder outer face protrusion part <NUM> and the second inner holder inner face concave part <NUM> is released, so that the first inner holder <NUM> can ascend relative to the second inner holder <NUM> (see <FIG> and <FIG>). Therefore, the cosmetic substance existing in the second hollow part <NUM> is exposed to the outside.

In the meantime, even though the first inner holder <NUM> ascends relative to the second inner holder <NUM>, the first inner holder lower face protrusion part <NUM> is caught to the inner member upper face part <NUM> which serves as a stopper so as to prevent the first inner holder <NUM> from ascending relative to the second inner holder excessively.

Moreover, the second inner holder <NUM> has a rib disposed therein, so that the first inner holder <NUM> can move relative to the second inner holder <NUM> by a guide of the rib. For this, the first inner holder <NUM> has a cut part. Therefore, the holder can ascend and descend by such a rail guide manner.

Now, a use process of the stick type cosmetic container <NUM> according to the present invention will be described as follows. First, in the initial operational state (non-use state), the outer container <NUM> covers the outside of the handle <NUM>, and the holder <NUM> is located at the lower end (See <FIG> and <FIG>. In this state, the first inner holder <NUM> and the second inner holder <NUM> may get in contact with the inner member upper face part <NUM>.

After that, in the normal operational state (use state), the user first removes the outer container <NUM>, and then, manipulates the handle <NUM> to lift up the holder <NUM>, so that the cosmetic substance, such as a lipstick, accommodated in the holder <NUM> is exposed to the outside from the inner container <NUM>. Then, the user can apply make-up using the exposed cosmetic substance (see <FIG> and <FIG>). When the user finishes make-up, the user manipulates the handle <NUM> to lift down the holder <NUM>, and after that, combines the outer container <NUM> with the outer face of the handle <NUM>. So, the stick type cosmetic container returns to the initial operational state (non-use state).

If most of the cosmetic substance has been used and the user cannot use the cosmetic substance in the normal operational state, or if the user wants to disassemble or separate the components in order to abandon the cosmetic container, it is called the final use state (residual quantity use state). In the final use state, the user manipulates the handle <NUM> to lift up the holder <NUM> to the maximum, and when additional external force is applied, the first inner holder <NUM> and the second inner holder <NUM> which have been operated integrally are separated from each other. Therefore, when the first inner holder <NUM> is ascended from the second inner holder <NUM>, the residual quantity of the cosmetic substance existing in the second hollow part <NUM> is exposed to the outside. Therefore, the user can use the residual quantity of the cosmetic substance (see <FIG> and <FIG>).

<FIG> and <FIG> illustrate the state where the first inner holder <NUM> is ascended from the second inner holder <NUM> to the maximum.

In the meantime, in the second preferred embodiment of the present invention (see <FIG>), the inner container upper part <NUM> is disposed at the upper side of the inner container <NUM>, and the inner container upper part <NUM> has the inner member upper face part. The inner member upper face part protrudes toward the inner face of the container, that is, toward the first hollow part <NUM>. The inner container upper part <NUM> may be a stopper getting in contact with the second inner holder upper end part <NUM>.

That is, when the holder <NUM> is lifted up, the second inner holder upper end part <NUM> gets in contact with the inner container upper part <NUM> of the protruding shape, and due to the stopper structure, the second inner holder <NUM> can be prevented from being removed or protruding outwardly from the inner container <NUM>.

Moreover, in the second preferred embodiment of the present invention, an inner holder upper face concave part <NUM> may be disposed at the upper face of the first inner holder <NUM>. The inner holder upper face concave part <NUM> serves to fix the cosmetic substance, and instead of the inner holder upper face concave part <NUM> or in addition to the inner holder upper face concave part <NUM>, a protrusion type member may be disposed.

In the above description, the configuration and effects of the stick type cosmetic container <NUM> are described in an aspect of use. Hereinafter, referring to the drawings, in connection with manufacturing of the stick type cosmetic container <NUM>, especially, in relation with a filling method of the cosmetic substance, will be described. <FIG> is a view showing a stick type cosmetic container of a filling type according to a third preferred embodiment of the present invention.

As shown in the drawing, in order to fill the cosmetic container <NUM> with the cosmetic substance, there are an upper end filling method for filling the holder <NUM> with the cosmetic substance from the upper end of the cosmetic container <NUM> (see <FIG>) and a lower end filling method for filling the holder <NUM> with the cosmetic substance from the lower end of the cosmetic container <NUM> (see <FIG>).

The structures described in the first and second preferred embodiments can be all applied to the upper end filling and the lower end filling. Furthermore, the structure of the cosmetic container may be changed or components may be added according to the upper end filling and the lower end filling. For instance, as shown in <FIG>, for the lower end filling of the cosmetic substance, an inner cover <NUM> may be disposed at the upper end of the inner face of the outer container <NUM> of the cosmetic container <NUM>, and a filling holder member <NUM> may be disposed at the central part of the lower end of the handle <NUM>.

Next, <FIG> is a schematic diagram showing an operational process of the stick type cosmetic container containing a cosmetic substance. <FIG> illustrates the initial operational state (non-use state), <NUM>(b) illustrates the normal operational state (use state), and <NUM>(c) illustrates the final use state (residual quantity use state). As shown in the drawings, a cosmetic substance (f) is accommodated in the second inner container <NUM>, and if the quantity of the cosmetic substance (f) is enough, the first inner container <NUM> and the second inner container <NUM> may be lifted up and down integrally. If most of the cosmetic substance is exhausted and the residual quantity exists just in the second inner container <NUM>, the first inner container <NUM> is separated from the second inner container <NUM>, and then is lifted up relative to the second inner container <NUM> so as to expose the residual quantity of the cosmetic substance (f) to the outside.

As described above, the stick type cosmetic container <NUM> according to the present invention can exhaust the remaining amount of cosmetics without waste, and can be separated and discharged after being used completely. Moreover, the stick type cosmetic container according to the present invention has a simple and convenient structure to enhance productivity and usability.

The above description is only exemplary, and it will be understood by those skilled in the art that the invention may be embodied in other concrete forms without changing the technological scope and essential features. Therefore, the above-described embodiments should be considered only as examples in all aspects and not for purposes of limitation. For example, each component described as a single type may be realized in a distributed manner, and similarly, components that are described as being distributed may be realized in a coupled manner.

The scope of the present invention is defined by the appended claims, and encompasses all modifications or alterations derived from meanings and the scope of the appended claims.
