As shown in FIGS. 1 to 7, a container 100 according to one embodiment of the present invention includes an inner container 1 having an opening 11, an outer container 2 accommodating the inner container 1, and a ceiling covering the opening 11 of the inner container 1. It comprises a surface 3 , a stage 6 and a pushing member 7 .

The inner container 1 is a bottomed cylindrical container with an open top, and is capable of containing contents. In the present embodiment, the case of a container that discharges a fluid as the content will be described, but the container that discharges a solid as the content may also be used.

The fluid discharged by the container 100 according to this embodiment is not limited as long as it exhibits fluidity at least during discharge and can be pushed out of the container 100 through the opening 32 of the container 100 . A fluid may be a liquid, such as a liquid or liquid mixture of pure substances. Furthermore, the fluid may be, for example, a solution, a dispersion liquid such as an emulsion, or a suspension, or may be in a state called gel, slurry, paste, cream, or the like. The fluid may contain powder or may mainly contain powder. The fluid may be a mixture of the above-mentioned fluid and a gas such as nitrogen, rare gas, or air, and contained in the inner container 1 in the form of foam. Also, the fluid may be pasty or creamy with a viscosity similar to or higher than that of water.

Fluids include skin care products such as lotions, milky lotions, face creams, serums, facial cleansers, and cleansing agents, or makeup cosmetics such as basic cosmetics, foundations, makeup bases, concealers, liquid eye shadows, liquid cheeks, and liquid lip products. Personal care products (daily hygiene products) such as sunscreens, hand soaps, body soaps, hair shampoos, hair dyes, styling agents, hand creams, body creams and body lotions, fragrance products and the like.

When the contents are solids, the solids are solid cosmetics or semi-solid cosmetics such as particularly hard hair sticks, hair waxes, lipsticks, and solid beauty essences (for example, those with similar hardness to stick beauty essences). It may be a powder, bar soap, or the like. Foods such as cheese and butter may also be used.

The material constituting the container 100 is not particularly limited, but resin materials, metal materials, wooden products, and the like can be mentioned. As the resin material, for example, polyethylene (PE), polypropylene (PP), polystyrene (PS), polyethylene terephthalate (PET), polyvinyl chloride (PVC), melamine resin, epoxy resin, silicon resin, or the like can be used. . These resins may be used singly or in combination of two or more.

As shown in FIG. 4, the inner container 1 has an opening 11 at the top, a peripheral wall 12 as a side surface, and a bottom surface 13. The bottom surface 13 has a second fitting hole 15 formed in the center. , at least a pair of arc-

shaped wall surfaces

14 , 14 are erected radially outward of the second fitting hole 15 . The arc-

shaped wall surfaces

14, 14 stand upright with respect to the bottom surface 13 in a stationary state, but stand up so as to be radially operable (flexible) when a radial force is applied. A male screw 16 is formed at the upper end of the outer peripheral surface of each of the

arcuate wall surfaces

14 , 14 . Although the male screw 16 has one thread in this embodiment, it may have a plurality of threads. A support cylinder portion 25 of the outer container 2, which will be described later, is inserted into the second fitting hole 15, but there is a gap between the outer peripheral surface of the support cylinder portion 25 and the inner peripheral surfaces of the arc-

shaped wall surfaces

14, 14. formed. Further, inside the inner container 1, a stage 6 and a pushing member 7 are provided.

The outer container 2 is a bottomed cylindrical container having an opening 21 at the top, and has a peripheral wall 22 as a side surface and a bottom surface 23. A first fitting hole 24 is formed in the center of the bottom surface 23. A support tube portion 25 is erected upward from the first fitting hole 24 . By inserting the support tube portion 25 into the second fitting hole 15 of the inner container 1 , the outer container 2 accommodates the inner container 1 in a relatively rotatable manner. The opening 21 of the outer container 2 is located below the opening 11 of the inner container 1 when the inner container 1 is accommodated in the outer container 2, and the upper portion of the peripheral wall 12 of the inner container 1 is exposed from the outer container 2. ing. As a result, the user can hold the outer container 2 with one hand and the peripheral wall 12 or the top surface 3 of the inner container 1 with the other hand and relatively rotate the inner container 1 or the outer container 2. .

As shown in FIG. 6, the support cylinder part 25 has a protruding part 26 on the inner peripheral surface thereof, on which an elastic part 75 of the pushing member 7, which will be described later, is engaged. A pair of protrusions 26 are formed in this embodiment. The pushing member 7 and a shaft portion 623 of the stage 6 to be described later are inserted into the first fitting hole 24 . As shown in FIG. 7, the inner peripheral surface of the support cylinder portion 25, the inner and outer peripheral surfaces of the pushing member 7 (side surface 71), and the outer peripheral surface of the shaft portion 623 of the stage 6 have eight radial cross-sectional shapes. A rectangular positioning shape is formed. Thereby, the stage 6 and the pushing member 7 are non-rotatably fixed to the outer container 2 . The positioning shape may be a polygonal shape other than an octagonal cross-sectional shape of each member in the radial direction, such as a pentagon or hexagon, or may be a key and a key groove. Any shape may be used as long as it is non-rotatably fixed.

The stage 6 is a member that can be raised by rotating the inner container 1 or the outer container 2 and can be lowered when refilling the contents. The stage 6 has a circular gate valve 61 having an outer diameter equal to the inner diameter of the inner container 1 and a rotor 62 supporting the gate valve 61 and rotating together with the outer container 2 . The gate valve 61 and the rotating body 62 may be formed separately or may be integrally formed. The gate valve 61 may have a flat portion 611 and a peripheral wall 612 connected from the flat portion 611 and in close contact with the inner peripheral surface of the peripheral wall 12 of the inner container 1 . The sluice valve 61 and the inner peripheral surface of the peripheral wall 12 of the inner container 1 are in a state where the sluice valve 61 is stationary with respect to the inner peripheral surface of the peripheral wall 12 and when it moves upward with respect to the inner peripheral surface of the peripheral wall 12 . In this state, the contents contained in the inner container 1 are in liquid-tight contact so as not to leak below the gate valve 61 .

The rotating body 62 of the stage 6 has a truncated cylindrical shape, and has a peripheral wall 621 that is a side surface and a cylindrical shaft portion 623 erected in the center of the upper surface. A female screw 622 is formed on the inner peripheral surface of the peripheral wall 621 to engage with the male screw 16 formed on the upper end of the outer peripheral surface of the arcuate wall surfaces 14 , 14 . A ring-shaped gap 624 is formed between the peripheral wall 621 and the shaft portion 623, and from the opening at the lower end to the inside of the gap 624, the arc-shaped wall surfaces 14, 14 of the inner container 1, the support cylindrical portion 25 of the outer container 2, and the pushing member 7 is inserted. The shaft portion 623 of the rotating body 62, the arc-shaped wall surfaces 14, 14 of the inner container 1, the support cylinder portion 25 of the outer container 2, and the pushing member 7 are coaxially arranged, and the shafts of the inner container 1 and the outer container 2 are arranged coaxially. It coincides with the rotation center axis 10 . Further, as described above, the outer peripheral surface of the shaft portion 623 is formed with a positioning shape in the same manner as the inner peripheral surface of the support cylinder portion 25 and the inner and outer peripheral surfaces of the pushing member 7 (FIG. 7). . Thereby, the rotating body 62 (stage 6) is rotatably fixed to the inner container 1 and non-rotatably fixed to the outer container 2. As shown in FIG. In other words, the rotor 62 rotates integrally with the outer container 2 . That is, in the stage 6, when the rotating body 62 rotates together with the relative rotation of the outer container 2 with respect to the inner container 1, the female screw 622 and the male screw 16 of the inner container 1 are screwed together to interlock with each other. 1 so that it can move up and down.

The pushing member 7 is a member that is pushed by the user when refilling the contents, and functions as a switch that allows the stage 6 to be lowered. The pushing member 7 has a cylindrical shape with a bottom, and has a side surface 71 , a bottom surface 73 , and a third fitting hole 74 . A flange portion 72 is formed on the upper end portion of the side surface 71 and protrudes radially outward. As shown in FIGS. 3 and 6, the side surface 71 is formed with an elastic portion 75 . A pair of elastic portions 75 are formed on two opposing side surfaces 71 with one end connected to the side surface 71 and the other three end surfaces separated. In other words, the elastic portion 75 is formed in a cantilever beam shape by the end surface that is connected to the side surface 71, and is elastically deformable (FIG. 3). The elastic portion 75 is bent radially outward at the tip end of the cantilever-like elastic portion 75, and can be locked in a state where it abuts against the protruding portion 26 formed on the support cylinder portion 25 of the outer container 2. It has become. The abutting surfaces of the elastic portion 75 and the projecting portion 26 are slanted surfaces that are slanted with respect to the pressing direction. A force that pushes the distal end side of the elastic portion 75 radially inward acts due to the partial pressure due to the inclination angle.

The push-in member 7 is inserted inside the support tube portion 25 of the outer container 2, the elastic portion 75 is engaged with the protruding portion 26, and the flange portion 72 is in contact with the upper end of the support tube portion 25, whereby the support tube is pushed into the support tube. It is fixed to the part 25 . The peripheral edge of the collar portion 72 contacts and engages the inner peripheral surfaces of the arcuate wall surfaces 14, 14 (FIG. 5). The upper surface of the flange portion 72 is flush with the upper ends of the arcuate wall surfaces 14 , 14 , and the bottom surface 73 of the pushing member 7 is flush with the bottom surface 23 of the outer container 2 .

In addition, since the elastic portion 75 is in contact with the outer peripheral surface of the shaft portion 623 of the stage 6 in the state shown in FIGS. 4 and 6, the elastic portion 75 cannot be elastically deformed inward. However, when the contents are refilled, the bottom surface 73 of the push-in member 7 is pressed upward, so that the elastic portion 75 is elastically deformed to overcome the protruding portion 26 so that the locking can be released, and the push-in member 7 can move up and down. It has become. Moreover, when the elastic part 75 gets over the protruding part 26, a snapping sound is produced and a feeling of being pushed can be given to the user so that the push-in member 7 is pushed.

Also, the side surface 71 may be formed with a projection (not shown). As a result, the convex portion always abuts against the support cylinder portion 25 of the outer container 2, so that the push-in member 7 can be stopped at the pushed-in position, and the amount of movement of the push-in member 7 can be limited. Therefore, it is possible to prevent the pushing member 7 from falling off when pushed.

A shaft portion 623 of the stage 6 is inserted into the third fitting hole 74 of the pushing member 7 . Further, as described above, the inner peripheral surface and the outer peripheral surface of the pushing member 7 (side surface 71) are formed with a positioning shape similar to the inner peripheral surface of the support cylinder portion 25 and the outer peripheral surface of the shaft portion 623 ( Figure 7). Thereby, the pushing member 7 is non-rotatably fixed to the outer container 2 . In other words, the pushing member 7 rotates integrally with the outer container 2 .

The top surface 3 is a member that covers the opening 11 of the inner container 1, is detachable from the inner container 1, and has an opening 32 for discharging the contents to the outside. The top surface 3 may have a peripheral wall 31 for external fitting with the inner container 1 , or may not have the peripheral wall 31 when internally fitting with the inner container 1 . Also, the valve body 8 may be arranged in the opening 32 . In this embodiment, as the stage 6 rises, the internal pressure of the contents housed in the inner container 1 increases, causing the valve body 8 to rise and the contents to rise. and the top surface 3 to the upper surface of the top surface 3. As a result, the user can touch only the discharged amount of the contents to be used, so that the user can use the unused amount of the contents without touching it, and the contents can be hygienically stored. . When the content is a solid substance, the valve body 8 may not be provided, and the configuration of the top surface 3 can be made to correspond to the solid substance.

The container 100 may have a lid (not shown). The lid body may be, for example, a screw lid, which is screwed with a male screw formed on the outer peripheral surface of the peripheral wall 22 of the outer container 2 to cover the inner container 1, the top surface 3, and the opening 21 of the outer container 2. It may be fixed so as to cover it. The lid body is not limited to a screw lid, and may be, for example, a snap type lid.

Next, the operation of the container 100 when refilling the contents will be described with reference to FIGS. 8A to 8D, 9, and 10. FIG. 8A-8D are cross-sectional views taken along line II-II in FIG. 2 for explaining the operation of the container during refilling. 9 is a sectional view taken along line II in FIG. 2 in the same state as FIG. 8C, and FIG. 10 is a sectional view taken along line II in FIG. 2 in the same state as in FIG. 8D.

FIG. 8A shows the container 100 in use. The states shown in FIGS. 4 and 6 are assumed to be initial states. When the inner container 1 or outer container 2 is relatively rotated from the initial state shown in FIGS. received and pushed upwards. The contents are ejected onto the upper surface of the top surface 3 through the opening 32 of the top surface 3 from between the raised stage 6 and the top surface 3 by pushing up the valve body 8 . FIG. 8A shows a state in which the amount of contents inside the inner container 1 is reduced as a result of the contents being discharged onto the upper surface of the top surface 3 through the opening 32 and the discharged contents being used. .

In this state, the elastic portion 75 of the pushing member 7 is in contact with the outer peripheral surface of the shaft portion 623 of the stage 6, and therefore cannot move (bend) radially inward. Therefore, even if the bottom surface 73 of the pushing member 7 is pressed, the elastic portion 75 cannot get over the protruding portion 26, and the engagement between the elastic portion 75 and the protruding portion 26 is maintained and not released. In other words, even if the bottom surface 73 of the push-in member 7 is accidentally pressed during use, the push-in member 7 will not operate, and the user can use the container 100 safely.

FIG. 8B shows a state in which the contents housed in the container 100 have been used up. The stage 6 further rises from the state shown in FIG. 8A and reaches the rising end position inside the inner container 1 (the position where the gate valve 61 of the stage 6 contacts the top surface 3). In this state, the elastic portion 75 of the pushing member 7 is not in contact with the outer peripheral surface of the shaft portion 623 of the stage 6, so that it can move radially inward (flexible). When the pushing member 7 is pressed, a pressing force acts on the abutting surfaces of the elastic portion 75 and the protruding portion 26, and since the abutting surfaces are inclined surfaces, the elastic portion 75 is pushed inward by the partial pressure of the pressing force. elastically deformed. Therefore, the elastic portion 75 can get over the protruding portion 26, and the engagement between the elastic portion 75 and the protruding portion 26 can be released. That is, when the stage 6 has reached the upper end position in the inner container 1, when the bottom surface 73 of the pushing member 7 is pressed (upward external force F1 is applied), the pushing member 7 moves up and down. It becomes possible. Further, until the stage 6 reaches the upper end position in the inner container 1, the collar portion 72 is engaged with the inner peripheral surfaces of the arc-shaped wall surfaces 14, 14, and the female screw 622 and the male screw 16 are screwed together. is maintained. It should be noted that the rising end position of the stage 6 is not limited to the position shown in FIG. 8B, and can be a position where the stage 6 reaches a predetermined height.

FIG. 8C shows a state in which the pushing member 7 is pushed. As the elastic portion 75 climbs over the projecting portion 26 and the engagement between the elastic portion 75 and the projecting portion 26 is released, the pushing member 7 moves upward. In this state, the collar portion 72 rises and is separated from the arcuate wall surfaces 14, 14 (male screw 16), and the engagement between the collar portion 72 and the arcuate wall surfaces 14, 14 is released. This allows the arcuate wall surfaces 14, 14 to move radially inward (flexible). Also, in this state, as shown in FIG. 9, the male screw 16 and the female screw 622 are screwed together. When a downward external force F2 is applied to the stage 6, the lower sloped surface of the thread of the female screw 622 presses the upper sloped surface of the thread of the male screw 16. A partial pressure is generated and the

arcuate walls

14, 14 are actuated radially inward. Then, the arc-shaped wall surfaces 14, 14 and the male screw 16 move radially inward, and the male screw 16 and the female screw 622 are disengaged, thereby lowering the stage 6. As shown in FIG. In the present embodiment, the peripheral wall 612 of the gate valve 61 of the stage 6 is in close contact with the inner peripheral surface of the inner container 1 to provide airtightness. It remains stationary even in a separated state, and does not descend unless a downward external force F2 is applied. When applying the external force F2, the user can remove the top surface 3 and press the stage 6 directly.

FIG. 8D shows a state in which the stage 6 descends and comes into contact with the pushing member 7. FIG. After descending, the stage 6 temporarily stops at a position where it abuts against the pushing member 7 . Also, as shown in FIG. 10, the male screw 16 and the female screw 622 are screwed together. From this state, when a downward external force F2 is further applied to the stage 6, the direction of the radially outwardly inclined surface of the elastic portion 75 and the radially inwardly inclined surface of the projecting portion 26 are substantially the same. Therefore, the elastic portion 75 is elastically deformed so that it can easily get over the protruding portion 26 located on the lower side. Therefore, the elastic portion 75 and the protruding portion 26 are locked, and the container 100 can be returned to its initial state. Thereby, the contents for refilling can be filled in the inner container 1 between the stage 6 and the top surface 3, and the container 100 can be used continuously.

As described above, in the container 100 of the present embodiment, after the stage 6 reaches a predetermined height, the stage 6 is lowered, and after the top surface 3 is removed, the content is filled in the inner container 1, and the top surface 3 After the opening 11 of the inner container 1 is covered with the inner container 1 or the outer container 2 , the contents can be discharged from the opening 32 of the top surface 3 by relatively rotating the inner container 1 or the outer container 2 . A user can lower the stage 6 by a simple operation of pushing the stage 6 after pushing the pushing member 7, and can easily refill the contents for refilling into the inner container 1.例文帳に追加Also, the easily refillable container 100 allows continued use of the container 100 and reduces the amount of plastic.
