Description

Technical Field

[0001] The present invention relates to a rod-shaped container with a replaceable core, and more specifically, to a rod-shaped container that allows for replacement by separating the used contents from a lower drive body and attaching a new replacement container to the lower drive body. Background Technology

[0002] Typically, cosmetic containers have a structure that allows various types of cosmetics to be contained while simultaneously allowing the cosmetics to be dispensed outside the container. The structure of such cosmetic containers can vary depending on the nature of the cosmetics contained within.

[0003] As an example, when the cosmetic is a solid type that can maintain a constant shape, it can be configured as a rod-shaped cosmetic container with a support plate at the bottom to support the cosmetic, and the cosmetic can be drawn out by raising and lowering this support plate. Specifically, the rod-shaped cosmetic container can have the following structure: it includes an outer container and an inner container that are configured to rotate relative to each other. If the user holds the outer container and rotates the inner container exposed on one side of the outer container or rotates a knob for driving the inner container, the cosmetic rises with the support plate, thereby drawing the cosmetic out of the outer container.

[0004] As described above, the stick-shaped cosmetic container has the advantage that the contents do not stick to the hands and can be applied directly to the desired area, so it can be used for a wide variety of products such as lipstick, sunscreen stick, sunscreen cream, and stick foundation.

[0005] However, these rod-shaped containers need to be manufactured in various non-circular shapes to allow for coating of larger areas or to narrow and curved areas. But when the contents are non-circular, the lifting mechanism for raising and lowering the contents and the knob for rotating the lifting mechanism are integrated into one unit, and these two parts cannot be separated. Therefore, there are technical limitations to making them replaceable. Consequently, when the contents are depleted, the entire rod-shaped container must be discarded and a new one purchased, leading to increased purchase costs and resource waste.

[0006] Therefore, there is a need to develop replacement rod-shaped containers that are not limited by the shape of the contents and can be replaced and used with new containers when the contents are exhausted. Summary of the Invention

[0007] The problem the invention aims to solve The present invention is proposed to solve the above-mentioned problems. One embodiment of the present invention provides a rod-shaped container, which can be replaced by separating the container body and the lower driving body and attaching a new replacement container to the lower driving body when the contents inside the container body are completely exhausted.

[0008] The technical problems to be solved by the present invention are not limited to those mentioned above. Other technical problems not mentioned can also be clearly understood by those skilled in the art to which the present invention pertains through the following description.

[0009] means for solving problems As a technical means to solve the above-mentioned technical problems, a rod-shaped container capable of replacing the core according to an embodiment of the present invention includes: a container body, in which contents are contained, and the container body guides the contents to move up and down within the container body; a lifting member, in which the contents are contained and moved up and down; and a lower drive body, including a knob, which is engaged with the lower part of the lifting member and causes the lifting member to rotate, the knob being capable of separating and engaging with the lower part of the lifting member, so that the container body and the lower drive body can be separated and engaged with each other.

[0010] Invention Effects According to one embodiment of the present invention, when the contents inside the container body are completely exhausted, the container body and the lower drive body can be separated, and then a new replacement container filled with contents can be combined with the separated lower drive body to perform replacement.

[0011] According to one embodiment of the invention, the rod-shaped container according to the invention can be configured such that the knob and lifting member can be separated and combined, thereby enabling a replaceable structure that is not limited by the shape of the contents. For example, it can be made into a thin and flat shape or an elliptical shape, resulting in a larger coating area and ease of use.

[0012] According to one embodiment of the present invention, the rod-shaped container of the present invention allows the user to separate the container body and the lower drive body with a simple operation such as pressing the release markings formed on both sides of the lower body, thus enabling easy replacement of the contents.

[0013] According to one embodiment of the present invention, the rod-shaped container with replaceable core can also be filled from the back by opening the lower part of the lower drive body.

[0014] According to one embodiment of the present invention, the replaceable core rod-shaped container according to the present invention is made of a single series of materials such as PP (plastic) and can be disposed of as a whole without the need for separate parts, thus having the advantages of easy recycling and environmental protection.

[0015] The effects that can be obtained by the present invention are not limited to those mentioned above. Other effects not mentioned can be clearly understood by those skilled in the art to which the present invention pertains through the following description. Attached Figure Description

[0046] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0047] Figure 1 This is a perspective view illustrating a rod-shaped container capable of replacing the core according to an embodiment of the present invention. Figure 2This is an exploded perspective view showing a rod-shaped container with a replaceable core according to an embodiment of the present invention. Figure 3 This is a diagram that breaks down and illustrates in more detail the state of the rod-shaped container capable of replacing the core according to an embodiment of the invention.

[0048] Reference Figures 1 to 3 According to one embodiment, a replaceable core rod-shaped container 1000 may include: a container body 100 for guiding the contents A to move up and down within the container body 100; a lifting member 200 housed within the container body 100 and for moving the contents A up and down; and a lower drive body 300 including a knob 320 engaged with the lower part of the lifting member 200 and for rotating the lifting member 200. At this time, the knob 320 can be separated from and engaged with the lower part of the lifting member 200, allowing the container body 100 and the lower drive body 300 to be separated and engaged with each other. Therefore, the container body 100 after the contents A have been used is separated from the lower drive body 300, and a new replacement container is engaged with the lower drive body 300, allowing the user to easily perform the replacement.

[0049] According to one embodiment, the contents A can be filled inside the container body 100. For example, the rod-shaped container 1000 of the present invention can be configured to be filled with the contents A via the open upper portion of the container body 100 in a front-filling manner.

[0050] Furthermore, in this invention, the filling of the contents A can also be achieved by injecting the contents A through the through injection hole 230 formed in the lifting member 200, as described later, via a rear filling method.

[0051] Therefore, the present invention can fill the contents A into the interior of the container body 100 using both front filling and rear filling methods.

[0052] According to one embodiment, content A is a solid, semi-solid, or balm-like dosage form, which can be a dosage form that is filled in a liquid state and then solidified into a solid or semi-solid form. According to the embodiment, content A can include cosmetics, topical skin agents, pharmaceuticals, etc. For example, content A can include sunscreen, UV protectant, multi-purpose cream, moisturizer, lipstick, foundation, CC cream, contour cream, BB cream, brightening cream, etc., but is not limited to these. It can include all types of substances that are filled with liquid and solidified as described above to form a rod shape, and can be lifted and drawn out by the rod-shaped container 1000 of the present invention.

[0053] According to one embodiment, the container body 100 can be formed as circular or non-circular. The rod-shaped container of the present invention is configured such that the knob and lifting member can be separated and combined, thereby enabling a replaceable structure that is not limited by the shape of the container body 100. Therefore, the container body 100 and the contents contained therein are not limited to a circular shape and can be made into a variety of shapes. For example, the container body 100 (and / or the contents contained therein) can be made into a circular, quadrilateral, triangular, elliptical, etc., and can also be made into a horizontally long and thin shape, a flat shape, etc., resulting in a large coating area and ease of use. However, it is not limited to these forms, and various embodiments can be applied.

[0054] According to one embodiment, the container body 100 can guide the contents A contained within the container body 100 to move up and down within the container body 100. That is, the container body 100 can be formed to be hollow inside, so that the interior of the container body 100 can provide space to accommodate the contents A and space to accommodate the lifting member 200 (described later). For example, the contents A is filled into the hollow container body 100, and the lifting member 200 is attached to the lower part of the contents A inside the container body 100. The contents A is moved up and down by the lifting member 200, thereby guiding the contents A within the container body 100.

[0055] According to one embodiment, a through portion 130 is formed at a lower position of the container body 100. For example, the through portion 130 can be formed by cutting through a lower position of the container body 100 to make it completely pass through vertically. The lifting member 200 is accommodated in the through portion 130 of the container body 100 with one side of the lifting member 200 exposed. That is, the rotating guide 220 described later can be coupled with the lower part of the rotating guide 220 exposed to the lower part of the through portion 130, thereby allowing the rotating guide 220 to be coupled with the knob 320.

[0056] According to one embodiment, the width of the lower portion of the container body 100 can be made narrower than the width of the upper portion of the container body 100, allowing the lower portion of the container body 100 to be embedded and joined to the interior of the lower drive body 300 (described later). Furthermore, a receiving groove (not shown) can be formed in the lower portion of the container body 100 to accommodate a portion of the upper part of the lower drive body 300. Therefore, when the container body 100 and the lower drive body 300 are joined, a portion of the lower portion of the container body 100 inserts into the inner surface of the lower drive body 300, and a portion of the upper part of the lower drive body 300 inserts into the receiving groove of the container body 100, thereby achieving a joint without any steps between them.

[0057] According to one embodiment, at least one engaging protrusion 110 may be formed in a region of the container body 100. For example, the engaging protrusion 110 may be formed in the lower portion of the container body 100, which is formed with a width narrower than the upper portion as described above; that is, the engaging protrusion 110 may be formed at a location in the portion of the container body 100 that inserts into the inner surface of the lower drive body 300. Furthermore, a pair of engaging protrusions 110 may be formed symmetrically on the front and rear surfaces of the container body 100, respectively. This engaging protrusion 110 is embedded into the engaging groove 311 formed in the lower body 310 of the lower drive body 300 (described later), thereby enabling the container body 100 and the lower drive body 300 to be fastened together.

[0058] According to one embodiment, the container body 100 and the lower drive body 300 may include at least one disengagement protrusion 120, 312. When the container body 100 and the lower drive body 300 are engaged, if an external force is applied to the area where the disengagement protrusion is formed, the container body 100 and the lower drive body 300 can be induced to separate by interference between the disengagement protrusions.

[0059] According to one embodiment, a release protrusion 120 may be formed in a lower region of the container body 100. For example, the release protrusion 120 may be formed on both sides of the lower part of the container body 100. This release protrusion 120 is formed at a position corresponding to the release protrusion 312 formed on the lower body 310 of the lower drive body 300 (described later), thereby contacting each other when the container body 100 and the lower drive body 300 are engaged. If the user applies pressure to the release pressing mark portion 313 formed on both sides of the lower body 310 in order to separate the container body 100 and the lower drive body 300, the release protrusion 120 formed on the container body 100 and the release protrusion 312 formed on the lower body 310 will push against each other, thereby making it easy to separate the container body 100 and the lower drive body 300.

[0060] According to one embodiment, in order to facilitate the movement of the detachment protrusion 120 and the detachment protrusion 312 formed on the lower body 310 (described later), the detachment protrusion 120 may be formed with a predetermined inclination. That is, if the detachment protrusion 120 formed on the container body 100 is formed to be increasingly inclined from the top towards the bottom, then the detachment protrusion 312 formed on the lower body 310 is formed to be increasingly inclined from the bottom towards the top.

[0061] Therefore, the protrusions 120 and 312 are formed to be close to each other when in contact, rather than spaced apart, which causes interference when the separation of the container body 100 and the lower drive body 300 is implemented by the container elasticity, and they can push each other.

[0062] According to one embodiment, an outer cap 500 may be attached to the outer surface of the container body 100. In order to prevent the contents A contained inside the container body 100 from drying out due to contact with air, the outer cap 500 may be formed to cover the outer surface of the container body 100 so as to seal the container body 100 when not in use.

[0063] According to one embodiment, an inner cap 400 may be attached to the upper part of the contents A. The inner cap 400 is used to prevent the contents A from contacting air before the user's initial use, thereby keeping the contents A moist. The inner cap 400 can be removed during use.

[0064] Figure 4 The front view and cross-sectional view show the state of the rod-shaped container capable of replacing the core according to an embodiment of the present invention, viewed from the front. Figure 5 This is a cross-sectional view showing the use of a rod-shaped container capable of replacing the core according to an embodiment of the present invention.

[0065] Reference Figures 4 to 5 According to one embodiment, the lifting member 200 can be housed inside the container body 100 and can move the contents A up and down. For example, the lifting member 200 can be attached to the lower part of the contents A housed inside the container body 100, so that when the lifting member 200 is rotated by the knob 320 of the lower drive body 300 (described later), the contents A is moved up and down to bring the contents A out of the container body 100.

[0066] This lifting component 200 may include: a lifting body 210, including a content receiving portion 211 and a lifting rod 212, the content receiving portion 211 being used to support the lower part of the content A, the lifting rod 212 extending from the lower part of the content receiving portion 211 and having a thread formed along the outer peripheral surface of the lifting rod 212; and a rotating guide 220, the lifting rod 212 being received in and engaged with the rotating guide 220, the rotating guide 220 having a thread corresponding to the thread formed on the lifting rod 212, the rotating guide 220 being engaged with a knob 320 and being rotated by rotating the knob 320.

[0067] According to one embodiment, the content receiving portion 211 of the lifting body 210 can support a portion of the lower part of the content A. For example, when the content receiving portion 211 is disposed inside the container body 100, when the content A is filled into the space inside the container body 100 through the through injection hole 230 described later, the content A is filled from the inner surface of the content receiving portion 211 and solidified, thereby the content A is filled and solidified in the form of being contained inside the content receiving portion 211.

[0068] Multiple protrusions can be formed on the inner surface of the contents receiving portion 211, thereby enabling the solidified contents A to be stably fixed in the contents receiving portion 211 and preventing its separation.

[0069] According to one embodiment, a lifting rod 212 extends and is formed at the lower part of the contents receiving portion 211. A thread is formed on the outer peripheral surface of the lifting rod 212, allowing it to be received and engaged inside the rotating guide 220 (described later). When the rotating guide 220 rotates, the lifting rod 212 is guided by the thread formed on the rotating guide 220, thereby enabling lifting and lowering relative to the rotating guide 220. For example, when the thread formed on the lifting rod 212 is engaged with the thread formed on the inner surface of the rotating guide 220, if the rotating guide 220 is rotated by rotating the knob 320, the lifting rod 212 is guided by the thread formed on the inner surface of the rotating guide 220, thereby enabling lifting and lowering. Therefore, the lifting rod 212 lifts and lowers relative to the rotating guide 220 to lift and lower the lifting body 210, thereby allowing the contents A to be led out to the upper part of the container body 100.

[0070] According to one embodiment, a thread corresponding to the thread formed on the outer peripheral surface of the lifting rod 212 can be formed on the inner surface of the rotary guide 220. Furthermore, the rotary guide 220 can be hollow, allowing the lifting rod 212 to be accommodated within the inner surface of the rotary guide 220. That is, a thread is formed at a location on the hollow inner surface of the rotary guide 220.

[0071] According to one embodiment, at least one locking protrusion 221 may be formed on the outer peripheral surface of the rotary guide 220. For example, multiple locking protrusions 221 may be formed on the outer peripheral surface of the rotary guide 220, and the multiple locking protrusions 221 of the rotary guide 220 may be formed vertically to be embedded and engaged in the multiple locking grooves 321 formed on the inner peripheral surface of the knob 320 (described later) along the vertical direction.

[0072] Accordingly, with the lower part of the rotating guide 220 exposed to the lower part of the through portion 130 of the container body 100, the rotating guide 220 is engaged with the knob 320. When the rotating guide 220 and the knob 320 are engaged in the vertical direction, no interference occurs between the locking protrusion 221 and the locking groove 321, thus making engagement easy and separation easy. Therefore, with the container body 100 and the lower drive body 300 engaged, the rotating guide 220 and the knob 320 rotate as a unit, which can be used as a structure for drawing out the contents A inside the container body 100. Moreover, there is no mutual interference when separating the container body 100 and the lower drive body 300, thus achieving a structure that can be easily separated.

[0073] According to one embodiment, a hollow through-hole 230 can be formed in the lifting body 210 and the rotating guide 220. For example, a hollow through-hole 230 with the central portion completely penetrated can be formed in the lifting body 210 and the rotating guide 220.

[0074] Through this through injection hole 230, rear filling can be achieved using the space inside the container body 100.

[0075] Furthermore, after the filling is completed via the through injection hole 230, a replacement cap 331 is attached to the through injection hole 230, thereby sealing the through injection hole 230.

[0076] Figure 6 This is an enlarged perspective view showing the joint between the container body and the lower drive body according to an embodiment of the present invention.

[0077] Reference Figure 6 According to one embodiment, a lower drive body 300 may be attached to the lower part of the container body 100.

[0078] The lower drive body 300 is combined with the lower part of the container body 100 and the lower part of the lifting member 200 (specifically the rotation guide 220), so that the lifting member 200 can be rotated.

[0079] According to one embodiment, the lower drive body 300 may include a lower body 310 attached to the lower part of the container body 100.

[0080] According to one embodiment, a knob receiving space for accommodating a knob 320 and a container body receiving space for accommodating the lower part of the container body 100 can be formed on the inner side of the lower body 310. For example, the interior of the lower body 310 is hollow to accommodate the knob 320. When the container body 100 and the lower drive body 300 are combined, the lower part of the container body 100 is accommodated in the interior of the lower body 310, and the lower part of the rotation guide 220 accommodated in the container body 100 is combined with the knob 320 accommodated in the interior of the lower body 310, thereby forming a stable rod-shaped container 1000.

[0081] According to one embodiment, an opening 314 may be formed on the side of the lower body 310. For example, the lower body 310 may be formed such that both sides are completely cut off and opened, so that a portion of the knob 320 housed inside the lower body 310 is exposed to the outside through the opening 314.

[0082] Thus, when the user holds and rotates a portion of the knob 320 that is exposed to the outside through the opening 314, the lifting member 200 (specifically, the rotation guide) coupled with the knob 320 is driven to draw the contents A toward the upper part of the container body 100.

[0083] According to one embodiment, the knob 320 can be inserted and assembled through the opening 314 of the lower body 310. For example, after assembling the knob 320 through the front surface of the container, the container body 100 can be embedded and joined in the vertical direction.

[0084] According to one embodiment, the lower body 310 may include a mating groove 311 for engaging with the mating protrusion 110 of the container body 100. The mating groove 311 may be formed at a location on the inner surface of the lower body 310 (e.g., a sidewall), but its location is not limited. The mating groove 311 is formed in an inwardly recessed groove shape at a location on the lower body 310, and its shape corresponds to the shape of the aforementioned mating protrusion 110 of the container body 100. Therefore, the container body 100 and the lower drive body 300 (specifically, the lower body) can be fastened by accommodating the mating protrusion 110 of the container body 100. The number of such mating grooves 311 may be the same as the number of mating protrusions 110 formed on the container body 100.

[0085] According to one embodiment, the lower body 310 may include detachment protrusions 312 formed to correspond to the detachment protrusions 120 of the container body 100. For example, the detachment protrusions 312 may be formed on the upper sides of the inner surface of the lower body 310.

[0086] This detachment protrusion 312 can be formed at a position corresponding to the position formed by the detachment protrusion 120 formed on the aforementioned container body 100. That is, when the container body 100 and the lower drive body 300 are combined, the detachment protrusion 312 formed on the lower body 310 and the detachment protrusion 120 formed on the container body 100 are formed at a position where they are in contact with each other.

[0087] Therefore, in order to separate the container body 100 and the lower drive body 300, if the user applies pressure to the release markings 313 formed on both sides of the lower body 310 (described later), the separation of the container body 100 and the lower drive body 300 is induced by the interference of the release protrusions 120 formed on the container body 100 and the release protrusions 312 formed on the lower drive body 300.

[0088] According to one embodiment, as described above, in order to facilitate the pushing of the release protrusion 312 and the release protrusion 120 formed on the container body 100, the release protrusion 312 may be formed with a predetermined inclination. In this case, the inclination of the release protrusion 120 of the container body 100 and the inclination of the release protrusion 312 of the lower body 310 are formed to correspond to each other, and the release protrusions 120 and 312 are formed to be tightly attached to each other when they come into contact with each other, rather than being spaced apart from each other, and to push each other when the separation of the container body 100 and the lower drive body 300 is implemented by the elasticity of the container.

[0089] According to one embodiment, a release pressing mark 313 may be formed on the outer surface of the lower body 310 where the release protrusion 312 is formed. For example, the release pressing mark 313 may be formed at one position on each side of the outer surface of the lower body 310.

[0090] In this case, the release press mark 313 can indicate the part where the release protrusion 120 of the container body 100 and the release protrusion 312 of the lower body 310 abut against each other. That is, the release press mark 313 is an indicator indicating the separation position where the container body 100 and the lower drive body 300 can be separated when the user presses the release press mark 313 part.

[0091] According to one embodiment, the lower body 310 can accommodate a knob 320. The knob 320 can be embedded and accommodated inside the lower body 310 via the opening 314 of the lower body 310, so that when the lower drive body 300 is engaged with the container body 100, it can engage with the lower part of the rotation guide 220 exposed to the lower part of the through portion 130 of the container body 100.

[0092] This knob 320 can be combined with the lower part of the rotation guide 220. When the user rotates the knob 320 to one side or to the other side, the rotation guide 220 combined with the knob 320 rotates, thereby raising and lowering the lifting member 200, and thus leading the contents A to the upper part of the container body 100.

[0093] According to one embodiment, at least one locking groove 321 may be formed on the inner peripheral surface of the knob 320. For example, a portion of the inner peripheral surface of the knob 320 may be cut along the vertical direction to form a plurality of protrusions and recesses, thereby forming a plurality of locking grooves 321.

[0094] The aforementioned locking protrusion 221 of the rotary guide 220 is embedded in the plurality of locking grooves 321 along the vertical direction, thereby realizing the combination of the knob 320 and the rotary guide 220. When the knob 320 is rotated, the rotary guide 220 can rotate together with the knob 320 through the locking protrusion 221 combined with the locking groove 321.

[0095] Figure 7 This is a perspective view from another direction showing the lower part of a rod-shaped container 1000 capable of replacing the core according to an embodiment of the present invention.

[0096] Reference Figure 7 According to one embodiment, the lower drive body 300 may further include a lower cap 330 detachably attached to the lower part of the lower body 310.

[0097] The lower cap 330 can be attached to the lower part of the lower body 310. For example, the lower cap 330 can be detachably attached to the lower part of the lower body 310 so that it can be opened when performing rear filling. Therefore, when the rod-shaped container 1000 is initially manufactured, in order to perform rear filling using the internal space of the container body 100, the lower part of the lower body 310 is formed to be open. If the contents A are filled into the interior of the container body 100 through the through injection hole 230 of the lifting member 200 and the filling is completed, the lower part of the lower body 310 can be sealed by attaching the lower cap 330.

[0098] According to one embodiment, a replacement cap 331 may be disposed in the central portion of the lower cap 330. That is, the replacement cap 331 may be accommodated and attached to the inside of the through injection hole 230, and its lower part may be attached to the central portion of the lower cap 330, so that when the lower cap 330 is attached or removed from the lower body 310, the replacement cap 331 will also separate from the through injection hole 230, thereby allowing the through injection hole 230 to open.

[0099] When the lower cap 330 is attached to the lower part of the lower body 310 after the back filling is completed, a portion of this replacement cap 331 is accommodated and attached to the interior of the through injection hole 230, thereby sealing the through injection hole 230.

[0100] According to one embodiment, all components of the aforementioned rod-shaped container 1000 can be formed from a single series of materials. For example, it can be formed from plastic materials, specifically, materials such as polyethylene series, polypropylene series, PET, PE, PP, PCR, PETG, etc. However, it is not limited to this; any material can be used as long as it forms the shape of the rod-shaped container 1000 without causing the contents A to deteriorate. Therefore, the container as a whole can be recycled without separating and discarding parts, thus offering the advantages of easy recycling and environmental friendliness.

[0101] Figure 8 This is a cross-sectional view showing a replacement container according to an embodiment of the present invention.

[0102] Reference Figure 8 According to one embodiment, the replacement container 600 may include: a container body 610, in which contents A are contained, the container body 610 guiding contents A to move up and down within the container body 610; a lifting member 620, in which contents A are contained and moved up and down within the container body 610; and a replacement container cap 630, attached to the upper part of the container body 610.

[0103] According to one embodiment, the container body 610 and lifting member 620 of the replacement container 600 can be formed with the same configuration and combination structure as the aforementioned container body 100 and lifting member 200.

[0104] According to one embodiment, the replacement container cap 630 may include: an inner surface fastening portion 631, which is tightly fitted to the inner peripheral surface of the container body 610 and formed with a predetermined curvature in the inward direction to prevent the contents A from leaking to the outside during the process of filling the contents A by utilizing the rear filling method of the inner space of the container body 610; and an outer surface fastening portion 632, which is formed by bending from the inner surface fastening portion 631 toward the outer peripheral surface of the container body 610 and is tightly fitted to the outer peripheral surface of the container body 610 in a manner that surrounds a portion of the outer peripheral surface of the container body 610, so as to again prevent the contents A filled inside the container body 610 from leaking to the outside. The inner surface fastening portion 631 and the outer surface fastening portion 632 may be formed as a pair, but are not limited thereto.

[0105] Figure 9 This is a perspective view showing the replacement process of a rod-shaped container capable of replacing the core according to an embodiment of the present invention.

[0106] Reference Figure 9 According to one embodiment, the user applies pressure to the release markings 313 on both sides of the lower body 310 of the rod-shaped container 1000 after all contents A have been used up.

[0107] If the user applies pressure to the position of the release marking 313 formed on the lower drive body 300, the release protrusion 120 of the container body 100 and the release protrusion 312 of the lower body 310 push against each other, and the engagement protrusion 110 disengages from the engagement groove 311 by the container elasticity generated by the user's pressure, thereby separating the container body 100 and the lower drive body 300 vertically.

[0108] Thus, after the container body 100, which is separated from the lower drive body 300, is completely separated from the lower drive body 300, a new replacement container 600 filled with contents A is embedded and combined with the lower drive body 300.

[0109] At this time, it is preferable to adjust the position of the rotating guide 220 and the knob 320 to achieve the connection between the rotating guide 220 exposed at the lower part of the through portion 130 of the container body 100 of the replacement container 600 and the knob 320 of the lower drive body 300.

[0110] Then, by pressing the new replacement container 600 down completely, the coupling protrusion (not shown) formed on the container body 610 of the replacement container 600 is inserted into the coupling groove 311 formed on the lower body 310 of the lower drive body 300, thereby combining the container body 610 of the replacement container 600 and the lower drive body 300, thus ending the replacement of the rod-shaped container 1000.

[0111] Thus, according to the rod-shaped container 1000 of the present invention, after the container body 100 with all contents A used up is separated from the lower drive body 300, a new replacement container 600 is fastened to the lower drive body 300, thereby enabling replacement.
