Description

  The present invention relates to a replaceable container for storing and using a detachable container, and more particularly to a replaceable container for storing cosmetics, medicines, and the like.

  Use a removable container filled with cosmetics such as wax for hair care in the main body container, and after using the cosmetics, take out the inner container and discard it, A so-called refillable container is known in which a container is purchased and stored in a main body container.

  For example, Japanese Patent Laid-Open No. 2001-327325 discloses a double container including a bottomed cylindrical inner container and a bottomed cylindrical outer container that accommodates and fits the inner container so that it can be inserted and removed. ing. This double container has a maker name, a pattern, a quality label, etc. on the outer surface of the inner container. On the other hand, the outer container is transparent, and the inner container passes through the wall of the outer container. It is comprised so that a pattern can be visually recognized. If a pattern is applied to the outer surface of the outer container, the pattern may fade or peel off over a long period of use, which may impair the aesthetic appearance of the container. Such a problem can be avoided.

  There is also known a cosmetic container configured such that a detachable container does not easily come out of the main body container. For example, Japanese Patent No. 2572579 discloses a flange formed by expanding the outer diameter of the flange at the opening end of a bottomed cylindrical refill container, and the outer end of the flange being folded along the side surface of the refill container. The cosmetic container which provided the flange with a crown which consists of these in the said refilling container is disclosed. This crowned flange is fitted to the open end of the cosmetic stuffing member disposed inside the cosmetic container body, whereby the refill container can be closely attached. Moreover, the crowned flange is formed in a size that is easy for the user to grasp when taking out the refill container, thereby facilitating removal.

  Furthermore, a refillable container for the purpose of preventing withdrawal is disclosed in registered utility model No. 2588201. In the container disclosed in this gazette, a pair of tongue pieces are suspended from the lower end of the mouth portion of the inner container, a protrusion is provided on the tongue piece, and the protrusion is fitted into a notch provided on the inner surface of the outer container. By combining, the inner container is fixed to the outer container. Further, when the inner container is taken out, the inner container is easily taken out by pressing the tongue piece to release the fitting.

JP 2001-327325 A Japanese Patent No. 2572579 Registered Utility Model No. 2588201

  By the way, in the replaceable container as described above, it is preferable that the replaceable container is formed to be thin within an allowable limit range by using a relatively inexpensive raw material in consideration of being discarded after the use of the cosmetic. Thereby, the weight of the waste to be discarded can be reduced, and an environmentally friendly product can be provided. In addition, since the manufacturing cost can be reduced, cosmetics can be provided to consumers at a low price.

  However, if the replaceable container is formed in this way, its mechanical strength becomes relatively weak, and there is a problem that it is easily damaged. For example, if a design such as a pattern is applied to the outer surface of the replaceable container, the consumer may use the replaceable container alone, but in such a case, in a container with low mechanical strength, Damage or the like can easily occur due to dropping during use.

  Further, even when the replaceable container is stored and used in the main body container as originally intended, there is a risk of damage if the replaceable container unexpectedly comes out of the main body container and falls during use. On the other hand, if the replaceable container is structured so as not to be removed from the main body container in order to prevent it from coming out, replacement after using the cosmetic becomes inconvenient. This is especially inconvenient if the edges of the replaceable container must be pulled up with a finger to release the fit. This is because cosmetics or the like often adheres to the part gripped with a finger, and then the hand slips.

  Therefore, in view of the above circumstances, the present invention is environmentally friendly and prevents the replacement container from being used differently from the intended use mode, thereby reducing the risk of breakage of the replaceable container and the replaceable container. An object of the present invention is to provide a replaceable container that can be easily attached and detached.

  The replaceable container according to the present invention is exchanged by engaging a main body container composed of an outer container and an inner container, a bottomed cylindrical replaceable container detachably housed in the inner container, and the main body container. A lid that holds the possible container in an airtight manner. The inner container has a through hole, the replaceable container has a first protrusion that can be forcibly fitted into the through hole, and the outer container has a push-up means that can push up the first protrusion. Have.

  According to the above configuration, since the first protrusion of the replaceable container is forcibly fitted into the through hole of the inner container, the replaceable container can be firmly fixed to the inner container. Accordingly, it is possible to prevent the replaceable container from being accidentally pulled out during use of the refill container. On the other hand, when taking out the replaceable container, the protrusion of the replaceable container is pushed up by the push-up means provided on the outer container. Therefore, the replaceable container can be easily detached from the main body container without pulling up the upper edge of the replaceable container.

  Moreover, since a main body container is comprised from an outer container and an inner container, these can be spaced apart in a bottom part. Moreover, since the push-up means is provided in the outer container, the push-up means can be moved relative to the inner container in which the replaceable container is stored.

  Preferably, the first protrusion is formed so as to prevent the replaceable container from standing upright stably. In this way, it is very inconvenient to use the replaceable container alone, and the user is forced to use the replaceable container by storing it in the inner container. Therefore, the replaceable container is surely protected by the main body container, and a potential and effective solution such as damage prevention can be provided.

  It is useful that the shape of the tip of the first protrusion is any of an inclined surface, a spire, and a hemisphere. Further, when the outer diameter of the replaceable container is R (mm) and the outer diameter of the first protrusion is r (mm), it is preferable that the relational expression r / R ≦ 0.5 is satisfied. Further, when the outer shape of the replaceable container is R (mm) and the height of the first protrusion is h (mm), it is beneficial to satisfy the relational expression 0.04 ≦ h / R ≦ 0.5. is there. This reliably prevents the replaceable container from standing steadily independently.

  Moreover, it is preferable that the first protrusion has a bulging portion on a side surface thereof. Thereby, it is possible to easily and surely fit the first protrusion into the through hole.

  The push-up means has a second protrusion that can contact the first protrusion, and an elastic deformation portion that allows the second protrusion to move so as to push up the first protrusion. The second protrusion and the elastically deformable portion are preferably formed integrally with the outer container at the bottom of the outer container. Thereby, the 1st projection part can be pushed up reliably.

  The elastic deformation portion is opposed to the first support portion projecting from the side surface of the opening provided at the bottom portion of the outer container, the ring coupled to the first support portion, and the first support portion of the ring. It is more preferable that the second support portion protrudes from the inner surface of the ring at a position and a disk portion coupled to the second support portion, and the second protrusion is provided on the disk portion. is there.

  The disk part is supported by the first support part, the ring, and the second support part, and since these have elasticity, they can easily move in the vertical direction. In addition, since the disk portion is provided with a second protrusion that contacts the first protrusion of the replaceable container, the second protrusion can be easily moved up and down, and the replaceable container can be pushed. Raising is facilitated. Therefore, the exchangeable container can be easily taken out.

  Further, the replaceable container further includes a first rotation preventing member on the upper end side wall portion, and the inner container engages with the first rotation preventing member on the upper end inner wall portion and the replaceable container and the content. It is preferable to further have a second anti-rotation member for preventing relative rotational movement with the container. This prevents rotation of the replaceable container so that the replaceable container is securely fixed without moving in the inner container. Therefore, it is more effectively prevented that the replaceable container is unexpectedly pulled out.

  It is more preferable that both or one of the first rotation preventing member and the second rotation preventing member is a linear knurling. According to this, the exchangeable container is smoothly stored in the inner container.

  The outer container and the inner container are preferably fitted so as not to be detachable from each other. In this way, when the replaceable container is pushed up by the push-up means and removed, it is possible to prevent the inner container from coming off.

  Hereinafter, preferred embodiments of a replaceable container according to the present invention will be described with reference to the drawings. In the drawings, the same members are denoted by the same reference numerals, and redundant description is omitted. For convenience of explanation, the dimensional ratios and the like in the respective drawings are different from those of the actual replaceable container. The expression “up and down direction” in the following description indicates the direction of the arrow D as shown in the figure as appropriate, and the expression “upward” or “upward” or “upper” at the “upper end” The direction indicated by the arrow D is indicated.

  Although a side view including a partial cross section of the replaceable container shown in the present embodiment is shown in FIG. 9, for convenience of explanation, first, each component will be described below.

  The inner container of the replaceable container according to the present embodiment will be described with reference to FIGS. 1 and 2. The inner container constitutes a main body container and houses a replaceable container described later. The inner container can be made of a material such as PP (polypropylene) or PE (polyethylene). The color of the inner container may be arbitrarily selected and may be transparent, but is preferably colored and opaque. The applicant of the present application considers the design of the entire replaceable container and considers making it white.

  FIG. 1A is a side view including a partial cross section showing the inner container 3. As shown, the inner container 3 is mainly composed of an inner container jar 30. The inner container jar 30 has a substantially hemispherical shape, has a through-hole 31 at the bottom thereof, and has a knurling 35 extending linearly at the upper inner wall portion. Furthermore, the inner container jar 30 is provided with a shoulder portion 32, a leg portion 33, and a screw thread 34.

  As shown in FIGS. 2A and 2B, the through hole 31 is provided substantially at the center of the bottom of the inner container jar 30. The through-hole 31 is provided for fitting and inserting a protrusion at the bottom of the replaceable container described later. As shown in FIG. 1B, the open end of the through hole 31 is undercut to form a stepped portion 31a. The step portion 31 a is provided to ensure the fitting between the inner container 3 and the protrusion of the replaceable container and to firmly fix the replaceable container to the inner container 3. The height (undercut amount) of the stepped portion 31a can be set to about 0.3 mm, for example.

  The shoulder portion 32 has a role of positioning and fitting the inner container 3 with respect to the outer container 5. As shown in FIG. 1 (A), the shoulder portion 32 extends substantially perpendicularly from the outer surface of the inner container jar 30 and is formed to bend along the outer surface at the tip. Further, as shown in FIG. 1C, a step 32a is provided at the edge of the shoulder 32. As will be described later, the stepped portion 32 a is provided to fit the inner container 4 to the outer container 5. The height of the stepped portion 32a can be set to, for example, about 0.25 mm to 0.55 mm.

  A thread 34 is provided on the upper outer wall of the inner container jar 30. A lid, which will be described later, is screwed onto the screw thread 34, whereby the replaceable container and the cosmetics that are the contents thereof are kept airtight.

  The knurling 35 is provided on the upper inner surface of the inner container 3 as described above. Specifically, as illustrated in FIG. 2A, the knurl 35 is formed by providing a plurality of grooves 35a (72 in this embodiment) at predetermined intervals in the inner container jar 30. The groove 35a extends in the vertical direction (see FIG. 1A) and has a size that can accommodate a vertical lett provided on the outer surface of the replaceable container described later. To illustrate the size of the groove 35a, the width (the length in the direction along the inner peripheral surface of the inner container jar 30) is about 1.2 mm, and the depth (the length along the thickness direction of the inner container jar 30). Is about 0.5 mm, and the height (the length along the vertical direction of the inner container jar 30) is about 4.3 mm.

  Referring to FIGS. 1A and 2B, the leg portion 33 has a cylindrical shape and is formed integrally with the inner container jar 30. Further, a vertical lett 33 a for positioning the inner container 3 with respect to the outer container 5 is provided on the outer peripheral surface of the leg portion 33. In the present embodiment, twelve vertical letts 33a are provided, and are arranged at an angular interval of 30 ° with the center of the inner container jar 30 as the center point, as shown in FIG.

  Next, the outer container constituting the main body container will be described with reference to FIGS. 3 to 5. FIG. 3A is a side view including a partial cross section showing the outer container. As shown, the outer container 5 is mainly composed of an outer container jar 50. The outer container jar 50 is made of, for example, PP (polypropylene) or PET (polyethylene terephthalate), and has a thickness of about 1 mm at the bottom and a thickness of about 1.6 mm at the side wall. . Further, the applicant of the present application considers the jar 50 to be translucent. This is because the color of the inner container 3, for example, white color can be seen through slightly, and a unique aesthetic full of luxury can be exhibited.

  The outer container jar 50 has a recess 52a shown in detail in FIG. The recess 52 a has an annular shape along the inner peripheral surface of the outer container 5. The recess 52a is provided so that a stepped portion 32a provided on the shoulder portion 32 of the inner container 3 is fitted, and the inner container 3 and the outer container 5 are integrated by this fitting.

  Moreover, the outer container jar 50 has the gate part 53 on the bottom part 50a in the inside. Referring to FIGS. 3A and 4A, the gate portion 53 has a cylindrical shape, and a knurl 55 is provided on the inner peripheral surface thereof. As illustrated in FIG. 4A, the knurl 55 is formed by providing a plurality of grooves 55 a (36 in the present embodiment) at predetermined intervals on the inner periphery of the gate portion 53. The groove 55a extends in the vertical direction (see FIG. 3A), and has a size that can accommodate the vertical lett 33a provided on the leg portion 33 of the inner container 3 described above. Although not limited, when the size of the groove 55a is exemplified, the width (the length in the direction along the inner peripheral surface of the outer container jar 50) is about 1.5 mm, and the depth (the outer container jar 50) The length along the thickness direction) is about 1.5 mm, and the height (the length along the vertical direction of the outer container jar 50) is 5 mm.

  Further, referring to FIG. 4A, a push-up means 57 for pushing up a protrusion of a replaceable container, which will be described later, is provided at substantially the center of the bottom 50a of the outer container jar 50. Here, the push-up means 57 will be described with reference to a perspective view shown in FIG. As shown in the figure, the push-up means 57 has a push button shape that can be pushed up from the bottom. The push-up means 57 is provided integrally with the bottom portion 50a of the outer container jar 50, a first support portion 57a protruding from the side surface of the opening 50b provided in the bottom portion 50a, and a ring coupled to the first support portion. 57b, a second support portion 57c protruding from the inner surface of the ring 57b at a position facing the first support portion 57a of the ring 57b, and a disk portion 57d coupled to the second support portion 57c. The disk portion 57d is provided with a cylindrical push-up protrusion 57e.

Referring to FIG. 5, the dimensions of the first support part 57a, the ring 57b, and the second support part 57c are illustrated. The outer diameter of the outer container 5 is about 70 mm, whereas the first support part 57a The width w _a is about 2 mm, the width w _{b of the} ring 57 _b is about 1 mm, and the width w _c of the second support portion 57 _c is about 2 mm. Moreover, the thickness of these members 57a-57c is about 1 mm similarly to the thickness of the bottom part of the outer container 5. FIG. Since the first support part 57a, the ring 57b, and the second support part 57c have the shapes as described above and are provided with the dimensions as described above, they can be easily bent. As a result, the push-up protrusion 57e is easily pushed upward. That is, the first support part 57a, the ring 57b, and the second support part 57c function as elastic deformation parts, and move the push-up protrusion part 57 up and down. The upward movement of the push-up protrusion 57 pushes up the protrusion of the replaceable container, which will be described later, and allows easy replacement of the replaceable container.

  Then, the main body container comprised from the inner container 3 and the outer container 5 mentioned above is demonstrated. FIG. 6 is a side view including a partial cross section showing the main body container. As illustrated, the main body container 1 is configured by fitting an inner container jar 30 into an outer container jar 50. Here, the leg portion 33 is inserted into the gate portion 53, and the vertical lett 33a is engaged with the groove 55a. The inner container jar 30 can be easily positioned with respect to the outer container jar 50 because the number of the vertical letts 33a is 12 and the number of the grooves 53a is 36.

  Further, a stepped portion 32 a (see FIG. 1C) provided on the shoulder portion 32 is fitted in a concave portion 52 a provided on the upper end opening 52. By this fitting, the inner container jar 30 and the outer container jar 50 are reliably integrated. This integration is solid enough that the user cannot easily separate the inner container 3 and the outer container 5. For this reason, when taking out the replaceable container, the inconvenience that the inner container 3 is detached is avoided.

  Subsequently, the replaceable container of the replaceable container according to the present embodiment will be described. FIG. 7A is a side view including a partial cross-sectional view showing the replaceable container according to the present embodiment, and FIG. 7B is an enlarged cross-sectional view of the protrusion of the replaceable container. (C) is a bottom view showing a replaceable container.

  Referring to FIG. 7A, the replaceable container 7 is mainly composed of a jar 70. The jar 70 has a substantially hemispherical shape and corresponds to the inner surface shape of the inner container 3 that houses the replaceable container 7. The jar 70 includes a protrusion 73 provided on the bottom, a screw thread 74 provided on the upper outer surface, and a flange 72 provided below the screw 74.

  A vertical lett 72a extending in the vertical direction (arrow D) is provided below the flange 72. In the present embodiment, six vertical letts 72a are provided at an angular interval of 60 ° with the center of the bottom of the jar 70 as the center point (see FIG. 7C). These vertical letts 72a engage with the grooves 35a provided in the upper inner surface of the inner container 3 described above. This engagement prevents the exchangeable container 7 from rotating with respect to the inner container 3.

  The protrusion 73 is provided outside the bottom of the jar 70 as shown in FIG. 7 (A), and has a cylindrical shape as can be seen from FIGS. 7 (B) and 7 (C). The protrusion 73 is fitted and inserted into the through-hole 31 of the inner container 3 when the replaceable container 7 is stored in the inner container 3. Therefore, it is formed in a dimension that can be fitted to the through hole 31.

  Further, an annular bulging portion 73 a along the circumferential direction is provided on the outer surface of the protruding portion 73. When the replaceable container 7 is stored in the inner container 3, the bulging part 73 a is fitted with a stepped part 31 a provided on the inner side surface of the through hole 31 of the inner container 3. Thereby, the replaceable container 7 is firmly fixed with respect to the inner container 3, and therefore, the replaceable container 7 can be prevented from unexpectedly coming out of the inner container 3 or the main body container 1.

  Although not limited, when the dimensions of the protrusion 73 and the bulging portion 73a are exemplified, the outer diameter of the protrusion 73 is about 7.2 mm with respect to the opening diameter of 7.3 mm of the through hole 31. Is about 5.2 mm and the height is about 2.7 mm. As shown in FIG. 7B, the bulging portion 73a has a bulging height of about 0.1 mm and a width w of about 1 mm.

  Next, another effect produced by the protrusion 73 will be described. In this embodiment, the outer diameter (R) of the replaceable container 7 is about 58.2 mm, whereas the diameter (r) of the protrusion 73 is about 7.2 mm, and r / R ≦ 0.5 Is satisfied. Moreover, since the height (h) of the protrusion is about 2.7 mm as described above, there is also a relationship of 0.04 ≦ h / R ≦ 0.5. When formed in this way, it becomes difficult for the protrusion 73 to erect the replaceable container 7 on a desk or the like. Moreover, even if it can be erected, it tilts with a slight impact. If tilted, the replaceable container 7 rolls like an arc because only the side surface and the projection 73 are in contact with the desk surface, and does not stably stand still. For this reason, it is very inconvenient to use the replaceable container 7 alone. Therefore, the user is forced to store the replaceable container 7 in the main body container 1 and use it. Therefore, the replaceable container 7 is protected by the main body container 1 as originally intended, and the possibility of breakage or the like is reduced.

  In this embodiment, the protrusion 73 of the replaceable container is formed in a cylindrical shape. However, the shape is not limited to this shape, and a rod shape having an inclined surface at the upper end (FIG. 11A) and a rod shape having a spire at the upper end ( 11 (B)) or a rod shape having a hemisphere at the upper end (FIG. 11C). Even with such a shape, the replaceable container cannot be placed in a stable state, and thus the above-described effects are exhibited.

  In the present embodiment, the jar 70 of the replaceable container 7 is made of PP (polypropylene) and has a thickness of 0.8 mm to 1.5 mm. According to the knowledge of the present inventors, when this type of container is formed of PP (polypropylene), the wall thickness is usually 2.0 mm to 2.4 mm. That is, it can be seen that the thickness of the jar 70 of the present embodiment is thinner than that of a normal container of this type. It can be considered that this is an effect produced because it must be stored in the main body container 1 and used.

  In addition, the replaceable container 7 has a thread 71 on the upper side wall portion of the jar 70. A temporary lid (not shown) having a corresponding female screw can be screwed onto the thread 71. This temporary lid is used for sealing and protecting the cosmetic in the replaceable container 7 until the consumer stores the replaceable container 7 in the inner container 3 and uses it after the manufacture.

  Finally, the overall shape of the replaceable container according to the present embodiment will be described. FIG. 9 is a side view including a partial cross section showing a replaceable container, and shows a state in which the above-described refillable container 7 is accommodated in the main body container 1 and a lid is attached.

  Referring to FIG. 9 together with FIGS. 6 and 7A, it can be seen that the replaceable container 7 (FIG. 7A) is stored in the main body container 1 (FIG. 6). Further, the replaceable container 10 has a lid 9, which is mounted by screwing a thread 94 provided in the lid 9 with a thread 34 of the jar 30 as shown in FIG. 9. Is done. A packing 96 is attached inside the lid 9, and the jar 70 and the cosmetic material therein are hermetically held by the packing 96.

  Here, when attention is paid to the protrusion 73 provided on the bottom of the jar 70, it can be seen that the fitting is inserted into the through hole 31 at the bottom of the inner container jar 30. Further, the vertical lett 72 a provided on the side portion of the jar 70 is engaged with the groove 35 a that defines the knurled of the upper end side wall portion of the inner container jar 30. In this way, the replaceable container 7 is firmly fixed with respect to the jar 30, thereby reliably preventing the replaceable container 7 from coming out.

  When attention is paid to the push-up protrusion 57e of the outer container jar 50, it can be seen that the protrusion 57e is inserted into the cylindrical protrusion 73. For this reason, when the push-up protrusion 57e moves upward, the protrusion 73 is reliably pushed up.

  The procedure for replacing the replaceable container 7 after using the cosmetic is described as follows. That is, the disk portion 57d of the push-up means 57 is pushed with the lid 9 removed. Then, the push-up protrusion 57e moves so as to push the protrusion 73 upward, and the engagement between the protrusion 73 and the through hole 31 is released by this movement. Therefore, the replaceable container 7 can be easily removed. Next, the newly purchased replaceable container 7 is stored in the inner container jar 30 and pressed, and the protrusion 73 of the replaceable container 7 is fitted into the through hole 31 of the inner container jar 30. Next, the temporary lid attached to the replaceable container 7 at the time of purchase is removed and the lid 9 is attached. In this way, the replaceable container 10 is in a state of being used for ordinary use.

  Hereinafter, the effect which the refill container 10 by this embodiment has is demonstrated. According to the replaceable container 10 according to the present embodiment described above, the bulging portion 73 a provided in the protrusion 73 of the replaceable container 7 and the step 31 a provided in the opening end portion of the through hole 31 of the inner container 3 function. Thus, the replaceable container 7 is forcibly fitted to the inner container 3. Therefore, the replaceable container 7 can be firmly fixed to the inner container 3, and the replaceable container is prevented from unexpectedly coming out while the refill container is in use. Moreover, there is an advantage that the replaceable container 7 can be firmly fixed by a simple method of fitting the protrusion 73 and the through hole 31.

  On the other hand, when the replaceable container 7 is taken out from the main body container 1, the protrusion 73 of the replaceable container 7 is pushed up by the push-up means 57 provided on the bottom of the outer container 5. For this reason, the said container 7 can be easily removed from the main body container 1, without pulling up the upper edge part of the exchangeable container 7 with a finger | toe. Therefore, the convenience of the replaceable container 10 is improved.

  Moreover, since this protrusion 73 is formed so that the replaceable container cannot stand upright stably by itself, it is very inconvenient to use the replaceable container alone. Therefore, the user is forced to use the replaceable container 7 by storing it in the main body container 1. For this reason, the replaceable container 7 can be reliably protected by the main body container 1. Therefore, if used alone, it is possible to reduce the risk of damage or the like that is expected to occur frequently.

  Further, the push-up means 57 is provided integrally with an elastic deformation portion composed of the first support portion 57a, the ring 57b, and the second support portion 57c, and a disk portion 57d coupled to the second support portion 57c. And a push-up protrusion 57e. With this configuration, the push-up protrusion 57e can easily move up and down. The push-up protrusion 57e can act on the protrusion 73 to release the fitting between the protrusion 73 and the through hole 31 and push up the replaceable container 7. Therefore, the exchangeable container can be easily taken out.

  The interchangeable container 7 is firmly fixed without moving in the inner container 3 by the engagement of the groove 35 a defining the knurl 35 of the inner container 3 and the vertical lett 72 a of the replaceable container 7. Therefore, it is possible to more effectively prevent the replaceable container 7 from coming out unexpectedly. Further, prevention of rotation of the replaceable container 7 is also effective when the cosmetic material adhering to the inner surface of the replaceable container 7 is scraped with a finger when the cosmetic material in the replaceable container 7 is low.

  Furthermore, since both the groove 35a and the vertical lett 72a are formed along the vertical direction, the exchangeable container 7 is smoothly stored in the inner container 3.

  The outer container 5 and the inner container 3 are fixed and cannot be removed by fitting the stepped portion 32b provided in the shoulder portion 32 of the inner container 3 and the recess 52a provided in the upper end opening of the outer container 5 to each other. Has been. For this reason, both can be simply fixed to each other without using an adhesive or the like, and when the replaceable container 7 is pushed up and removed by the push-up means 57, the inner container 3 is detached. It can be surely prevented.

  Further, by forming the main body container 1 from the outer container 5 and the inner container 3, the push-up means 57 is provided at the bottom of the outer container 5, and the push-up projection 57e of the push-up means 57 is moved relative to the inner container 3. be able to. If the main body container is formed as a single unit in a bulk shape, the push-up means must be separately prepared and attached, which may cause a problem that an extra manufacturing process is required. However, according to the present invention, since the push-up means 57 can be integrally formed with the bottom 50a of the outer container 5, such a problem is solved.

  In this embodiment, the outer container is formed to be translucent and the inner container is formed to be white and opaque. However, this allows the inner container to be dimly seen through the outer container and exhibits a unique aesthetic. Is done. For this reason, the user can attach to the replaceable container and can be used for a long time. Therefore, the effect of reducing the amount of waste, which is an advantage of the replaceable container, will be permanent.

  Further, according to the above embodiment, even if the design of the appearance of the replaceable container is obsolete, the replaceable container cannot be seen because the inner container is opaque, and the appearance of the main body container depends on the appearance of the replaceable container. There is no harm. Therefore, it is possible to reversely use this and intentionally give a unique color to the replaceable container. For example, if it has a brand color (blue in the registered trademark “Dove”) that is well known to consumers like the present applicant, the replaceable container can be colored in that brand color. By doing so, the risk of consumers purchasing the wrong inner container is also reduced.

  Further, for example, when the cosmetic is a hair care wax, it is possible to match the outside of the replaceable container to various wax colors. According to this, the consumer can select the wax that suits his / her preference by looking at the color of the replaceable container.

  Furthermore, the “hard type” may be red, and the “matte type” may be green. Thereby, the effect that it can prevent that a consumer misidentifies a type can also be show | played.

  As mentioned above, although embodiment was shown and it demonstrated in detail about the refill container which concerns on this invention, this invention is not limited to the said embodiment, A various deformation | transformation is possible.

  In the above embodiment, the bulging portion 73a is formed in an annular shape, but is not limited to this as long as the protruding portion 73 can be fitted into the through hole 31. For example, it may be a hemispherical protrusion, and it goes without saying that one or a plurality of protrusions may be provided. Even if it does in this way, it is because the above-mentioned effect can be exhibited.

  Moreover, although the cylindrical shape and the rod shape are illustrated as the shape of the protruding portion 73 of the replaceable container 7, and the slope shape, the spire shape, and the spherical shape are illustrated as the shape of the tip portion of the protruding portion, the replaceable container 7 stands upright. However, the shape is not limited to these as long as the shape is prevented.

  Furthermore, the shape of the push-up protrusion 57e provided on the bottom of the outer container 5 is not limited to a cylindrical shape, and can be appropriately changed according to the shape of the protrusion 73 of the replaceable container 7. For example, when the upper end of the protrusion 73 is hemispherical, the push-up protrusion 57e can be shaped like a rod, and the tip can be shaped like a bowl that can accept the hemisphere. As a result, the push-up protrusion 57e is reliably engaged with the protrusion 73, and the protrusion 73 is reliably pushed up.

  In the present embodiment, the inner container 3 is provided with the knurl 35, and the replaceable container 7 is provided with the vertical lett 72a. However, the inner container 3 is provided with the vertical lett and the replaceable container 7 is provided with the knurled. It doesn't matter. This also prevents the exchangeable container 7 from rotating with respect to the inner container 3.

  Furthermore, the above-described dimensions and materials are merely examples, and are not limited to the descriptions, and may be appropriately changed. Needless to say, the shapes of the inner container 3, the outer container 5, and the replaceable container 7 are not limited to those illustrated, and may be selected as appropriate. In particular, the push-up means 57 is not limited to the illustrated dimensions and the like as long as the push-up protrusion 57e can move up and down easily. Furthermore, although the design in which the outer container 5 is translucent and the inner container is white is illustrated, it is needless to say that the design is not limited to such a design.

  Moreover, although the replaceable container of the replaceable container according to the present invention has been described as a so-called single-use container that is discarded after use, it is needless to say that the container can be collected and recycled.

  As described above, according to the replaceable container according to the present invention, since the first protrusion of the replaceable container is forcibly fitted into the through hole of the inner container, the replaceable container is It is firmly fixed. Therefore, it is possible to prevent the replaceable container from being accidentally pulled out during use of the refill container. On the other hand, when the replaceable container is taken out, the protrusion of the replaceable container is pushed up by the push-up means provided on the outer container, and the fitting of both is released. Therefore, the replaceable container can be easily detached from the main body container without pulling up the upper edge of the replaceable container.

  Moreover, since the first protrusion is formed so that the replaceable container cannot stand upright stably, it is very inconvenient to use the replaceable container alone. The exchangeable container must be stored in the inner container and used. For this reason, the replaceable container is reliably protected by the main body container.

  Therefore, replaceable containers are always used with the main body container even when the mechanical strength is relatively low due to consideration for the environment, even if the mechanical strength is relatively low. It will be protected.

  In other words, the present invention is environmentally friendly, prevents the use of the replaceable container from being different from the intended use, reduces the risk of breakage of the replaceable container, and allows easy replacement of the replaceable container. Providing a type container is provided.
