In FIG. 1, reference numeral 1 denotes a connectable bottle, in which a plastic upper bottle 10 and a lower bottle 20 are detachably connected in two upper and lower stages via a plastic connecting member 30. As shown in FIGS. 2 and 3, the upper bottle 10 is composed of a cap 13 detachably screwed to the upper bottle body 11 and the mouth 12 of the upper bottle body 11, and is the lower side of the cap 13 in the mouth 12. A ring-shaped collar portion 14 is projected in the horizontal direction to prevent the cap 13 from being over-closed. On the outer peripheral side surface of the cap 13, a large number of vertical grooves 15 for preventing slipping when the cap 13 is turned by a finger to open and close are engraved at equal intervals in the circumferential direction.
At the center of the bottom of the upper bottle body 11, a substantially columnar connecting recess 17 having a female screw portion 16 for connecting the lower bottle 20 is provided.

The lower bottle 20 has the same shape as the upper bottle 10 except for the connecting recess 17, and is detachably screwed to the mouth portion 22 of the lower bottle body 21 and the lower bottle body 21 as shown in FIGS. 4 and 5. It is composed of the combined caps 23, and a ring-shaped collar portion 24 is projected horizontally on the lower side of the cap 23 in the mouth portion 22 to prevent the cap 23 from being over-closed. .. On the outer peripheral side surface of the cap 23, a large number of vertical grooves 25 for preventing slipping when the cap 23 is turned by a finger to open and close are engraved at equal intervals in the circumferential direction.

The connecting member 30 detachably covers the cap 23 of the lower bottle 20 together with the flange portion 24, and makes the lower bottle 20 detachable from the connecting recess 17 of the upper bottle 10, and is shown in FIG. As described above, the male screw portion 31 detachably screwed with the female screw portion 16 of the upper bottle 10 has a tubular portion 32 formed on the outer peripheral side surface, and is oriented in the radial direction of the horizontal top surface 33 of the tubular portion 32. The lower side of the bent portion 34 provided is formed in a half-split shape, and by bending and returning in a valley fold along the bent portion 34, the left side portion of the connecting member 30 on the left side of the bent portion 34. The 35 and the right side portion 36 on the right side are formed so as to be openable and closable to the left and right with the bent portion 34 as an axis (see FIG. 7).
The inner space of the tubular portion 32 of the connecting member 30 is formed so as to just cover the cap 23 together with the flange portion 24. Further, on the inner circumference of the lower end portion on the left side portion 35 side and the right side portion 36 side of the tubular portion 32, four engagements are symmetrically engaged with the lower surface 26 of the flange portion 24 of the lower bottle 20. The joint portion 37 is projected toward the center of the tubular portion 32.

Next, the left side portion 35 and the right side portion 36 may be opened while the connecting member 30 is bent in a valley fold at the bent portion 34 of the top surface 33, and the connecting member 30 may be removed from the cap 23.
Since there is no male screw portion on the outer peripheral surface of the cap 23 of the lower bottle 20 and only a large number of flutes 25 for preventing slipping, it can be easily opened and closed by turning it with a finger.

According to this embodiment, since the upper bottle 10 and the lower bottle 20 are connected via a connecting member 30 that can be opened and closed in a half-split shape, a male screw portion is not provided on the outer periphery of the cap 23 of the lower bottle 20. It is possible to prevent the cap 23 from becoming difficult to open.

As shown in FIGS. 12 and 13, the connecting member 30A is extended in an L shape from the lower end of the tubular portion 32 to the outer periphery of the upper end portion of the lower bottle body 21, and is directed toward the lower bottle body 21 with fingers. A detent portion 38 may be provided that enables the connecting member 30A to detent the lower bottle 20 by pressing.
In this case, as shown in FIGS. 14 and 15, an engaging hole 39 is formed in the middle of the detent portion 38'of the connecting member 30A', and the side of the lower bottle body 21'of the corresponding lower bottle 20'. An engaging protrusion 27 that engages with the engaging hole 39 in a disengaged manner is provided at one or a plurality of locations on the peripheral surface, and the connecting member 30A'is attached to the lower bottle 20'and the engaging protrusion 27 is attached. When engaged with the engaging hole 39, the force for pressing the detent portion 38'toward the lower bottle body 21'with a finger is weak, or even when there is no pressing, the connecting member 30A'to the lower bottle 20' It may be possible to prevent the rotation of the bottle.

The side bottles 20 and 20'can be easily attached and detached.

Further, the upper bottle and the lower bottle may have different bottle heights and thicknesses. Specifically, the lower bottle body 21 of the lower bottle 20 in FIG. 1 may be thicker than the upper bottle 10 as in the lower bottle body 21-1 of the lower bottle 20-1 in FIG. Further, when the connecting member of the type shown in FIG. 13 is used, the detent portion 38-1 is made to have a long arm portion 38a as shown in the connecting member 30A-1 of FIG. 17, so that the lower bottle 20-1 having a large diameter is used. Can be used. Similarly, when the connecting member of the type shown in FIG. 15 is used, the detent portion 38-1'is made longer as the arm portion 38a'as in the connecting member 30A-1'with the engaging hole 39 in FIG. A lower bottle 20-1'having a large-diameter lower bottle body 21-1' with a protruding engaging protrusion 27 that engages with the engaging hole 39 can be used.

Even if the connecting member 30B is pulled upward, the engaging portion 37 is engaged with the flange portion 24 and the female screw portion 45 is in a state of being screwed with the male screw portion 28, so that the connecting member 30B is pulled from the cap 23. It will not come off.

The lower bottle 20B to which the connecting member 30B is attached is brought closer to the lower part of the upper bottle 10B from the side of the connecting member 30B, the lower bottle body 21B is grasped from the outside of the second outer tubular portion 43, and the upper bottle 10B is rotated. However, the male screw portion 31 of the connecting member 30B is screwed into the female screw portion 16 of the connecting recess 17, and the female screw portion 44 of the first outer tubular portion 42 is screwed to the lower outer periphery of the upper bottle body 11B. By screwing it into the portion 18, it can be fitted and detached freely. When the upper bottle 10B is rotated and screwed into the connecting member 30B, the connecting member 30B and the upper bottle 10B are brought together by pressing the second outer tubular portion 43 from the outside toward the center of the lower bottle 20B. There is no risk of rotation, and the upper bottle 10B and the lower bottle 20B can be integrally connected via the connecting member 30B easily and surely.

Between the lower outer circumference of the upper bottle body 11B and the first outer tubular portion 42, between the upper outer circumference of the lower bottle body 21B and the second lower tubular portion 43, the inner tubular portion 32B and the connecting recess 17 Since each of the spaces is in a screwed state and the engaging portion 37 is engaged with the flange portion 24, the upper bottle 10B and the lower bottle 20B are firmly connected via the connecting member 30B. Since they are connected, even if the upper bottle 10B is pulled upward with respect to the lower bottle 20B or bent in an oblique direction where the axes of the lower bottle 20B and the upper bottle 10B intersect, the connecting member 30B is connected from the connecting recess 17. The lower bottle 20B with the attachment will not come off, and only the lower bottle 20B will not come off while the connecting member 30B remains in the connecting recess 17.

On the contrary, when it is desired to separate the upper bottle 10B and the lower bottle 20B, the lower bottle 20B is grasped from the outside of the second outer tubular portion 43, and the second outer tubular portion 43 is pressed toward the center to be connected. The upper bottle 10B is rotated with respect to the lower bottle 20B in the reverse direction of the connection so that the member 30B and the upper bottle 10B do not rotate together, and the inner tubular portion 32B is screwed back from the connecting recess 17. The first outer tubular portion 42 is screwed back from the lower outer periphery of the upper bottle 10B to release the connection between the upper bottle 10B and the lower bottle 20B with the connecting member 30B.
Next, the left side portion 35B and the right side portion 36B may be opened to the left and right while bending the connecting member 30B in a valley fold at the bent portion 34 of the top surface 33, and the connecting member 30B may be removed from the upper portion of the lower bottle 20B including the cap 23.
Since there is no male screw portion on the outer peripheral surface of the cap 23 of the lower bottle 20B and only a large number of vertical grooves 25 for preventing slipping, it can be easily opened and closed by turning it with a finger.

According to this second embodiment, since the upper bottle 10B and the lower bottle 20B are connected via a connecting member 30B that can be opened and closed in a half-split shape to the left and right, a male screw portion is provided on the outer periphery of the cap 23 of the lower bottle 20B. It is not necessary to provide the cap 23, and it is possible to prevent the cap 23 from becoming difficult to open.
Further, between the lower outer circumference of the upper bottle body 11B and the first outer tubular portion 42, between the upper outer circumference of the lower bottle body 21B and the second outer tubular portion 43, the inner tubular portion 32B and the connecting recess. Since each of the 17 is in a screwed state and the engaging portion 37 is in a state of being engaged with the flange portion 24, the upper bottle 10B and the lower bottle 20B are firmly connected via the connecting member 30B. It can be connected, and it becomes difficult to separate even if an external force such as an impact is applied.

In the second embodiment, the lower bottle body is of the same type as the lower bottle body 21 of FIG. 5 without the male screw portion on the outer periphery of the upper portion, and the second outer tubular portion of the connecting member is a female screw. The upper bottle body may be of the same type as the upper bottle body 11 of FIG. 3 without the male screw portion on the lower outer periphery, and the first outer tubular portion of the connecting member may be a female screw. It may be a type without a part.
Further, the first outer tubular portion itself may be omitted, or the second outer tubular portion itself may be omitted.

Further, the upper bottle and the lower bottle may have different bottle heights and thicknesses. In this case, the first and second outer cylindrical portions have an upper and lower two-stage shape having different inner diameters, and the first outer cylinder. The inner diameter of the shaped portion may be matched with the outer diameter of the lower part of the upper bottle body, and the inner diameter of the second outer tubular portion may be matched with the outer diameter of the upper part of the lower bottle body.
For example, when the lower bottle body 21B of the lower bottle 20B in FIG. 19 is made thicker than the upper bottle 10B as in the lower bottle body 21B-1 of the lower bottle 20B-1 of FIG. 26, the connection of FIGS. 27 and 28. Like the member 30B-1, the first outer tubular portion 42 and the second outer tubular portion 43-1 have an upper and lower two-stage shape having different inner diameters, and the inner diameter of the first outer tubular portion 42 is the upper bottle body 11B. It is assumed that the inner diameter of the second outer tubular portion 43-1 is matched with the outer diameter of the upper part of the lower bottle body 21B in accordance with the outer diameter of the lower part of the bottle.
The extension portion 41-1 is formed from the outer circumference near the lower end of the inner tubular portion 32B to the outside in the radial direction, which is the farther side of the outer circumference of the upper bottle body 11B and the outer circumference of the lower bottle body 21B. It extends in a ring shape to near the outer circumference of 21B-1, and the first outer tubular portion 42 extends upward from the middle of the extension portion 41-1 and the outer circumference of the extension portion 41-1. A second outer tubular portion 43-1 extends downward from the edge. The first outer tubular portion 42 is provided with a female screw portion 44 that can be screwed with the male screw portion 18 provided on the lower outer periphery of the upper bottle body 11B, and the second outer tubular portion 43-1. Is provided with a female screw portion 45-1 that can be screwed with a male screw portion 28-1 provided on the upper outer periphery of the lower bottle body 21B-1.

As shown in FIGS. 33 and 34, the upper bottle 10C is composed of a cap 13C detachably screwed to the mouth portion (see reference numeral 12 in FIG. 3) of the upper bottle body 11C and the upper bottle body 11C, and is below the mouth portion. A ring-shaped flange portion 14 is projected on the side in the horizontal direction to prevent the cap 13C from being over-closed. On the outer peripheral side surface of the cap 13C, a large number of vertical grooves 15 for preventing slipping when the cap 13C is turned by a finger to open and close are engraved at equal intervals in the circumferential direction.

A plastic tubular cap opening tool 50 for removing the cap of the lower bottle, which will be described later, is fitted and detachably fitted to the cap 13C. Columnar engaging projections 61 and 61 as two engaging portions are projected on the top surface 60 of the cap 13C, and as shown in FIGS. 34 and 35, the corresponding portions of the cap opening tool 50 are provided. Engagement receiving holes 51, 51 as two engaging receiving portions are bored. When the cap opening tool 50 is fitted onto the cap 13C, the engaging protrusions 61 and 61 enter the engaging receiving holes 51 and 51 and engage in close contact with each other so that they cannot be easily disengaged. By picking it up with a tool and pulling it upward, the engaging protrusions 61 and 61 can be removed from the engaging receiving holes 51 and 51.
At the center of the bottom of the upper bottle body 11, a substantially columnar connecting recess 17C having a female screw portion 16C for connecting the lower bottle 20C is provided.

As shown in FIGS. 36 and 37, the lower bottle 20C is composed of a substantially tubular cap 23C that is detachably screwed into the lower bottle body 21C and the mouth portion 22C of the lower bottle body 21C. The mouth portion 22C is formed in two upper and lower stages of the upper small diameter cylinder portion 60 and the lower large diameter cylinder portion 61, and the small diameter cylinder portion 60 and the large diameter cylinder portion 61 have male screw portions 62 and 63, respectively. It is provided. The female screw portion 64 formed on the inner peripheral side of the cap 23C can be detachably screwed to the male screw portion 62 formed on the small diameter tubular portion 60. A male screw portion 65 that can be screwed with the female screw portion 16C is provided on the outer peripheral side of the cap 23C. The large-diameter tubular portion 61 and the cap 23C have the same outer diameter, and the male screw portion 63 of the large-diameter tubular portion 61 has the male screw portion 65 and the screw thread when the cap 23C is completely screwed into the small-diameter tubular portion 60. The spiral is continuous and can be screwed with the female screw portion 16C.

By picking the cap opening tool 50 with a finger and pulling it upward, the engaging protrusions 71 and 71 can be removed from the engaging receiving holes 51 and 51.
Since the cap 23C has a male screw portion 65 formed on the outer periphery, it is very difficult to remove the cap 23C by turning it with a finger as it is and trying to remove it from the mouth portion 22C. By fitting the cap opening tool 50 to the cap 23C and turning it together with the cap opening tool 50, it becomes difficult to slip and it becomes easy to remove.

Next, the operation of the above-described third embodiment will be described with reference to FIGS. 32 and 39. It is assumed that different types of contents are stored in the upper bottle 10C and the lower bottle 20C. Further, it is assumed that the cap opening tool 50 is fitted to the cap 13C of the upper bottle 10C.
The cap 23C is completely screwed into the small diameter tubular portion 60 of the mouth portion 22C of the lower bottle 20C so that the spiral of the male screw portion 65 and the spiral of the screw thread of the male screw portion 63 are continuous. Bring the lower bottle 20C closer to the connecting recess 17C of the upper bottle 10C from the side of the cap 23C, and while rotating the upper bottle 10C and the lower bottle 20C relative to each other, the cap 23C and the male screw portions 65 and 63 of the large diameter cylinder portion 61. Is screwed into the female screw portion 16C of the connecting recess 17C. As a result, the upper bottle 10C and the lower bottle 20C are integrally connected.
Even if the upper bottle 10C is pulled upward with respect to the lower bottle 20C, the cap 23C and the large-diameter cylinder portion 61 are screwed into the connecting recess 17C, so that the lower bottle 20C may come off from the connecting recess 17C. There is nothing to do.

On the contrary, when it is desired to separate the upper bottle 10C and the lower bottle 20C, the upper bottle 10C is rotated with respect to the lower bottle 20C in the reverse direction of the connection, and the cap 23C and the large diameter cylinder portion 61 are connected from the connecting recess 17C. It is screwed back to release the connection between the upper bottle 10C and the lower bottle 20C.
Next, the cap opening tool 50 fitted to the cap 13C of the upper bottle 10C is pulled upward by a finger to remove it, and is fitted to the cap 23C of the lower bottle 20C. At this time, the engaging protrusions 71 and 71 are engaged. Enter the receiving holes 51, 51 so that they engage in close contact with each other. When the cap opening tool 50 is turned by a finger, the engaging protrusions 71 and 71 are engaged with the engaging receiving holes 51 and 51, so that the cap 23C rotates together and the cap 23C is easily removed from the mouth portion 22C. be able to.
When tightening the cap 23C, after screwing it into the mouth portion 22C together with the cap opening tool 50, the cap opening tool 50 may be pulled upward with a finger to remove the cap opening tool 50 from the cap 23C.

According to the third embodiment, since the cap opening tool 50 without the male screw portion can be fitted and opened / closed to the cap 23C of the lower bottle on which the male screw portion 65 is formed, the cap 23C becomes difficult to open. You can avoid that.

In the third embodiment described above, an example in which nothing is formed on the outer peripheral side surface of the cap opening tool has been described, but similarly to the cap, a large number of anti-slip vertical grooves may be formed in the circumferential direction. good.
Further, the engaging portion provided on the cap of the upper bottle and the lower bottle and the engaging receiving portion provided on the cap opening tool are a columnar engaging protrusion and an engaging receiving hole, but the rectangular engaging protrusion. It may be an engaging receiving hole or an engaging receiving groove into which the rectangular body-shaped engaging protrusion is fitted. Further, an engaging portion may be provided on the cap side and an engaging portion may be provided on the cap opening side.
Further, the male screw portion of the large-diameter cylinder portion at the mouth of the lower bottle may be omitted.

Further, the upper bottle and the lower bottle may have different bottle heights and thicknesses. For example, when the lower bottle body 21C of the lower bottle 20C in FIG. 32 is made thicker than the upper bottle 10C as in the lower bottle body 21C-1 of the lower bottle 20C-1 in FIG. 40, a large size with a male screw portion 63 is attached. The diameter of the diameter cylinder portion 61-1 is increased, and as shown in FIG. 42, the connecting recess 17C-1 of the upper bottle 10C-1 is formed in two upper and lower stages having different inner diameters. The male screw portion 65 of the cap 23C can be detachably screwed into the female screw portion 81 formed in the small diameter portion 80 on the upper side of the connecting recess 17C-1. Then, from the middle of screwing the male screw portion 65 of the cap 23C to the female screw portion 81 of the small diameter portion 80, the female screw portion 83 formed in the lower large diameter portion 82 becomes the large diameter tubular portion 61-1. The formed male screw portion 63-1 can be detachably screwed.

The cap 23C is completely screwed into the small diameter tubular portion 60 of the mouth portion 22C of the lower bottle 20C-1 (see FIGS. 40 and 43), and the lower bottle 20C-1 is moved from the side of the cap 23C to the upper bottle 10C. Close to the connecting recess 17C-1 of -1, and while rotating the upper bottle 10C-1 and the lower bottle 20C-1 relative to each other, the cap 23C and the male screw portion 65 of the large-diameter tubular portion 61-1. , 63-1 are screwed into the small diameter portion 80 of the connecting recess 17C-1 and the female screw portions 81 and 83 of the large diameter portion 82. As a result, the upper bottle 10C-1 and the lower bottle 20C-1 are firmly and integrally connected (see FIG. 44). Even if the upper bottle 10C-1 is pulled upward with respect to the lower bottle 20C-1, the cap 23C and the large-diameter tubular portion 61-1 are screwed into the connecting recess 17C-1, so that the connecting recess 17C The lower bottle 20C-1 does not come off from -1.

In each of the above-described examples and modifications, the upper bottle, the lower bottle, the connecting member, and the cap opening tool are described as being made of plastic, but in addition to plastic, various materials such as metal and paper are used. It may be formed.

The present invention is applicable when it is desired to connect bottles with caps containing various contents such as foods such as seasonings, pharmaceuticals, machine parts, liquids, granules, and powders in two upper and lower stages.
