Hereinafter, a comparative example in comparison with the present invention will be described first, and then an embodiment of the present invention will be described.

1 is a longitudinal sectional view of a cap assembly of a comparative example.

The cap assembly 1A of the comparative example shown in Fig. 1 is composed of a cap 10 and a cap 20.

The inner cap 10 is a part that covers the inlet 31 of the bottle 30 and closes the inlet 31 thereof. The cap 20 is a part which covers the inlet 31 of the bottle 30 from above the inner cap 10 so as to cover the inner cap 10. [

1 shows a state in which the inner cap 10 is already wired to the inlet 31 of the bottle 30 so that the cap 20 is capped from the top of the inner cap 10, Indicating a state in the relationship.

The inner cap (10) has a main body (11) and a lid (12).

The main body 11 has a hollow portion 111 and a holding portion 112. The hollow portion 111 has a hollow shape having upper and lower openings communicating with the inlet 31 of the bottle 30 and the lower end portion 111a is inserted into the inlet 31 of the bottle 30 .

The holding portion 112 constituting the main body 11 has a hollow portion 111 and a lower end portion 111a inserted into the inlet 31 of the bottle 30 in cooperation with the upper end portion 32 of the bottle 30 So that the upper end 32 of the bottle 30 is gripped. The holding portion 112 is provided with a rib 112a protruding inwardly so that the rib 112a enters the concave portion 33 of the bottle 30 so that the holding portion 112 is inserted into the bottle 30 So that the upper end portion 32 is firmly attached and does not come off from the inlet 31 of the bottle 30. [

The cap 12 constituting the inner cap 10 has a lid portion 121 and a bonding portion 122. [ The lid portion 121 is a portion spreading in a plate shape above the hollow portion 111 so as to cover the hollow portion 111. [ The joining portion 122 is joined to the upper edge 111b of the hollow portion 111 for one week to close the opening of the upper end of the hollow portion 111 together with the lid portion 121. [ The main body 11 and the lid 12 constituting the inner cap 10 are one component integrally molded but the abutment portion 122 is easily broken when the lid portion 121 is pushed from above, When the joint part 122 is broken, the lid 12 becomes a part separate from the main body 11. This point will be described later.

By forming the depressed portion 121a on the upper surface of the lid portion 121 so as to secure a safety margin so that the abutment portion 122 is not inadvertently broken, the lid portion 121 is separated from the upper surface of the cap 20 The force is applied to the upper surface of the cap 20 so that the force does not reach the lid 121 even if the upper surface thereof is recessed.

The cap 20 constituting the cap assembly 1A of this comparative example has the outer skin 21, the accommodating portion 22 and the protruding portion 23.

The outer skin 21 is a hollow portion which is opened downward and covers the inner cap 10 and covers the opening 31 of the bottle 30 from above the inner cap 10. On the inner peripheral surface of the outer skin 21 is formed a female screw 211 which is screwed with a male screw 34 provided on the bottle 30. The cap 20 is attached and detached by turning.

The accommodating portion 22 is provided on the inner surface of the lid portion 121 to receive the lid portion 121 of the main body 11 and to receive the lid portion 121 of the lid portion 121, And surrounds the edge 121b.

The protruding portion 23 is a portion having a rib shape protruding inward from the inner peripheral surface of the accommodating portion 22. [ The projection 23 protrudes to a position where it interferes with the edge 121b of the lid 121 as described later.

1, after the contents are filled in the bottle 30, the lower end of the hollow portion 11 of the inner cap 10 and the lower end of the holding portion 112 The upper end 32 of the bottle 30 is bitten. That is, the inner cap 10 is wired to the bottle 30. The cap 20 is put on and rotated so that the cap is attached so that the protrusion 23 of the cap 20 shown in Fig. 1 is located just above the lid 121 of the inner cap 10 . Thereafter, shrink packaging or the like is performed, and the cap 20 is in a state in which it does not inadvertently rotate from the position shown in Fig.

Figs. 2 to 4 are diagrams showing movements at the time of opening by a consumer with respect to the comparative example shown in Fig. 1. Fig.

When the customer first tries to open the cap after handing it to the consumer in the state shown in Fig. 1, first the shrink package is removed, and then the cap 20 is further turned in the closing direction. 2 so that the edge 121b of the lid portion 121 of the inner stopper 10 interferes with the protruding portion 23 of the cap 20 The lid part 121 moves upward beyond the protruding part 23 as shown in Fig. 2, while elastically expanding the accommodating part 22. As shown in Fig. The interference between the edge 121b of the lid part 121 and the protruding part 23 of the cap 20 is released so that the receiving part 22 returns to its original shape and the protruding part 23 of the cap 20, And then returns to the lower side of the edge 121b of the lid part 121. [

When the cap 20 is further rotated in the closing direction to further move the cap 20 in the direction of the arrow A, the cap 20 presses the lid portion 121 and the joining portion 122 Destroyed. When the cap 20 is turned in the closing direction and the state shown in Fig. 3 is reached, the cap 20 is not turned in the closing direction, and the cap 20 is turned in the opening direction at this time. 4, only the lid 12 of the inner cap 10 is detached from the main body 11 and enters the receiving portion 22 of the cap 20, so that the cap 20 and the bottle 30 . Since the protrusion 23 is formed in the cap 20, the lid portion 121 is continuously held in the accommodating portion 22 of the cap 20 thereafter.

In the case of the comparative example shown in Figs. 1 to 4, the inner cap 10 can be opened by rotating the cap 20 in the one-end closing direction when the cap 20 is opened for the first time, The action is unnecessary, and thus the usability is greatly improved.

5 is a diagram showing the change in torque when the cap 20 is rotated in the one-end closing direction in the first opening of the cap 20 in the comparative example shown in Figs. 1 to 4. Fig.

The cap 20 is moved in the direction indicated by the arrow A in Fig. 2 and the edge 121b of the lid portion 121 of the inner cap 10 Of the cap 20 interfere with the protruding portion 23 of the cap 20 to expand the accommodating portion. At this time, as shown in the area (a) of Fig. 5, the force (torque) for turning the cap 20 increases. When the cap 20 is further turned in the closing direction, the lid portion 121 moves above the protruding portion 23 and the torque is temporarily lowered (region (b)). If the cap 20 is further turned in the closing direction, the cap 20 is now pressed against the lid 121 and the cap 20 is further turned in the closing direction, so that the joint 122 is broken while the torque is increased (region (c)). Thereafter, the cap 20 is not turned in the closing direction, and the cap 20 is removed by rotating the cap 20 in the opening direction at this time.

5, in the case of the cap assembly 1A of the comparative example described above, when the cap 20 is rotated in the closing direction to open the inner cap 10, There is a peak P of the torque before reaching the lid portion 121 of the motor. Therefore, a customer who is not accustomed to handling the bottle with the cap assembly 1A is mistaken for the fact that the inner cap 10 has been opened with the passage of the peak of the torque P, The cap 20 is turned in the opening direction and it is not noticed that the inner cap 10 is not opened until the cap 20 is opened. Even if the user unfamiliar with opening the cap 20 notices that the inner cap 10 is not opened, it is not noticed that the inner cap 10 is not opened unless the user goes through the area c, There is also the possibility of filing a claim.

On the basis of the above-described comparative example, the embodiment of the present invention will be described below.

6 is a longitudinal sectional view of the cap assembly of the first embodiment of the present invention.

The cap assembly 1B of the first embodiment shown in Fig. 6 is composed of a cap 40 and a cap 50. Fig.

The inner stopper 40 is a part that covers the inlet 61 of the bottle 60 and closes the inlet 61 (see FIG. 14). The cap 50 is a component that covers the inlet 61 of the bottle 60 from above the inner cap 40 to cover the inner cap 40. [

The inner cap (40) has a main body (41) and a lid (42).

The main body 41 has a hollow portion 411 and a holding portion 412. The hollow portion 411 has a hollow shape having an opening at the top and bottom which communicates with the inlet 61 of the bottle 60 and has a lower end portion 411a at the inlet 61 of the bottle 60, (See Fig. 15).

The hollow portion 411 is formed with a male screw 411c on the outer circumferential surface of the hollow portion 411 so as to surround the outer circumferential surface of the hollow portion 411 in a spiral manner and screwed into the female screw 541 of the cap 50.

The holding portion 412 constituting the main body 41 has a hollow portion 411 and a lower end portion 411a inserted into the inlet 61 of the bottle 60 in cooperation with the upper end portion 62 of the bottle 60 So that the upper part 62 of the bottle 60 is wound. A rib 412a is formed in the holding part 412. The rib 412a enters the concave part 63 (see Fig. 14) of the bottle 60, The upper end 62 of the bottle 60 is firmly attached to the bottle 60 and does not come off from the inlet 61 of the bottle 60.

The cap 42 constituting the inner cap 40 has a lid portion 421 and a bonding portion 422. [ Of these, the lid portion 421 is a portion that spreads in a plate shape from above the hollow portion 411 so as to cover the hollow portion 411. [ The joining portion 422 is joined to the upper edge 411b of the hollow portion 411 for one week to close the opening of the upper end of the hollow portion 411 together with the lid portion 421. [ The main body 41 and the lid 42 constituting the inner stopper 40 are a single component integrally molded but the abutment portion 422 is very easily broken when the lid portion 421 is pushed from above . When the joining portion 422 is broken, the lid 42 becomes a part separate from the main body 41.

A depressed portion 421a is formed on the upper surface of the lid portion 421 so as to secure a safety margin as large as possible so that the abutment portion 422 is not inadvertently broken, The force is applied to the upper surface of the cap 50 so that the force does not reach the lid portion 421 even if the upper surface thereof is recessed.

The cap 50 has an outer skin 51, a receiving portion 52, a protrusion 53, a threaded portion 54, and a hook 55 (see Fig. 7) Respectively.

The outer skin 51 has a hollow portion that is opened downward and covers the inner stopper 40 to cover a portion of the inner stopper 40 covering the inlet 61 of the bottle 60 to be.

The accommodating portion 52 is formed so as to protrude downward from the inner upper surface of the outer skin 51 and open downward so as to accommodate the lid portion 421 of the main body 41 inside thereof, And surrounds the edge 421b.

The projecting portion 53 is a portion having a rib shape protruding inward from the inner peripheral surface of the accommodating portion 52. The protrusion 53 protrudes to a position where it interferes with the edge 421b of the cover portion 421 when the cap 50 and the inner stopper 40 are assembled.

The screw engagement portion 54 has a shape protruding downward from the inner upper surface of the outer skin 51 in a cylindrical shape and opening downward. A female screw 541 is formed on the inner peripheral surface of the screw engagement portion 54 so as to be screwed with the male screw 411c formed on the outer peripheral surface of the hollow portion 411 of the inner stopper 40. That is, in the above-described comparative example, the cap 20 is opened and closed with respect to the bottle 30, but in the case of the cap assembly 1B of the first embodiment, the cap 50 is directly connected to the inner cap 40 As shown in Fig.

7 is a partially enlarged cross-sectional view of a cap constituting the cap assembly 1B of the first embodiment shown in Fig.

8 shows a part of the cap assembly 1B of the first embodiment shown in Fig. 6 in which the lid portion 42 of the inner cap 40 is accommodated in the accommodating portion 52 of the cap 50 Fig.

6 and 8, the lid portion 421 of the inner cap 40 is formed so as to protrude from the outer periphery of the receiving portion 52 of the cap 50. In the case of the cap assembly 1B of the first embodiment, (53). However, even if the outer skin 51 is slightly depressed by applying force to the outer skin 51 from above between the inner surface of the outer skin 51 and the lid portion 422, the force is applied to the lid portion 421 A hollow space is formed.

7, a hook 55 protruding inward is formed in a portion of the cap 50 just above the protruding portion 53 inside the accommodating portion 52. As shown in Fig. The hooks 55 are formed at a plurality of positions spaced apart from each other in the circumferential direction.

9 is a partially enlarged cross-sectional view showing a portion of the edge 421b of the lid portion 421 of the cross section cut horizontally of the lid portion 421 in a state in which the lid portion of the inner cap is inserted into the receiving portion of the cap.

9, on the circumferential surface 421c of the lid portion 421 of the inner stopper 40, a large number of rotation preventing protrusions 421d formed in a circumferential direction for a week are provided. The rotation preventing protrusion 421d is engaged with the hook 55 to prevent the positional relationship between the cap 50 and the inner cap 40 from deviating from the desired relationship.

Figs. 10 to 13 are explanatory views of a cap assembling method for the inner cap in the cap assembly of the first embodiment described with reference to Figs. 6 to 9. Fig.

First, as shown in FIG. 10, the inner stopper 40 is placed on the jig 70 that matches the shape of the inner stopper 40. The inner stopper 40 is provided with a rib 411e on the inner peripheral surface of the hollow portion 411. The rib 411e is inserted into a depression (not shown) of the jig 70 and prevented from rotating have.

Next, as shown in Fig. 11, the cap 50 is put on and the cap 50 is fixed. While the jig 70 is rotated in the direction of the arrow R1 as shown in Fig. 12, . Since the inner cap 40 is prevented from rotating with respect to the jig 70, the inner cap 40 is rotated together with the jig 70 so that the male thread 411c of the inner cap 40 is screwed into the screw And is screwed to the female screw 541 of the engaging portion 54. [ The edge 421b of the cover portion 421 of the inner cap 40 interferes with the protrusion 53 (see Fig. 7) formed on the inner peripheral surface of the receiving portion 52 of the cap 50, The receiving portion 52 is resiliently expanded by the lid portion 421 of the receiving portion 52. When the lid portion 421 passes over the protruding portion 53 and passes the upper surface side of the outer skin 51, Returns to its original shape. The protruding portion 53 is located below the lid portion 421 and supports the lid portion 421 even after the joint portion 422 is broken as described later so that the lid portion 421 is received As shown in Fig.

When the cover portion 421 sits on the projection portion 53, the receiving portion 52 is widened to increase the torque for rotating the jig 70. When the cover portion 421 exceeds the projection portion 53, the torque suddenly decreases . Therefore, by monitoring this torque, it is possible to detect that the lid portion 421 has crossed the protruding portion 53. Alternatively, instead of monitoring the torque, it is detected that the lid portion 421 has crossed the protruding portion 53 by the rotational angle of the jig 70 in the direction of the arrow R1 or the amount of movement in the direction of the arrow U It is also good.

It is difficult to stop the lid portion 421 just above the protrusion 53 by simply turning the jig 70 and the inner stopper 40 in the direction of the arrow R1 shown in Fig. , The lid portion 421 excessively goes up in the accommodating portion 52.

13, the jig 70 is lowered in the direction of the arrow D while rotating the jig 70 in the direction of the arrow R2 so that the lid portion 421 is brought into contact with the projecting portion 53, Lt; / RTI > When the lid portion 421 touches the protruding portion 53, the torque for rotating the jig 70 starts to increase. Therefore, by monitoring the torque, the lid portion 421 is lowered to just above the protruding portion 53 Can be detected. Alternatively, it may be detected that the lid portion 421 reaches directly above the protruding portion 53 by the rotation angle of the jig 70 in the direction of the arrow R2, the amount of descent in the direction of the arrow D, or the like.

In the cap assembly 1B of the first embodiment, the projecting portion 53 is located below the lid portion 421 by accommodating the lid portion 421 in the accommodating portion 52 through such assembling process, The cap 50 and the inner cap 40 are combined in a state in which the cap 421 is disposed at a position having an interval between the inner surface of the outer skin 51 and the inside of the accommodating portion 52. [

9, the rotation preventing protrusions 421d are engaged with the hook 55, and the inner stopper 40 is rotated by the degree of vibration at the time of transportation, as shown in Fig. 9, when the lid portion 421 is directly above the protruding portion 53. [ And the cap 50 are not inadvertently rotated and their positional relationship is maintained.

7 and 8, the hook 55 for preventing rotation is provided only at a portion directly above the protrusion 53, and is not provided at a further upper portion of the accommodating portion 52. [ This is because the cap 50 is opened together with the lid 42 of the inner cap 40 and then the cap 50 is closed again so that the rotation preventing protrusion 421d is in contact with the hook 55 When the cap 50 is closed again, the lid portion 421 is moved to the upper portion where the hook 55 is not provided, so that the cap 50 50 can be closed.

Although the jig 70 and the inner cap 40 are rotated or moved up and down in this example, the inner cap 40 is fixed, and a jig (not shown) for gripping the cap 50 is rotated or vertically moved It may be moved.

Thus, in the cap assembly 1B of the first embodiment, the inner cap 40 and the cap 50 are assembled before the wire is wound. That is, the cap assembly 1B can be manufactured by the manufacturer of the cap assembly 1B. Assembly of the inner cap 40 and the cap 50 needs to be performed under a fairly high-precision control. This assembly can be performed on the side of the maker of the cap assembly 1B because it is not necessary to impose a burden on the side of the food manufacturer to charge the contents of the bottle 30 with the technology and equipment for assembly thereof, One embodiment is also a preferred embodiment in this respect.

Next, a description will be given of a case where the cap assembly is wired to the bottle.

Figs. 14 and 15 are explanatory diagrams of a scene in which the cap assembly of the first embodiment is wired to a bottle.

The contents are filled in the bottle 60 and the cap assembly 1B is put on the flat plate 80 or the like as shown in Fig. 14 while the inner cap 40 and the cap 50 are combined . 15, the upper end portion 62 of the bottle 60 enters between the lower end portion 411a of the hollow portion 41 of the inner cap 40 and the holding portion 412, and the holding portion 412 The inner stopper 40 is firmly fixed to the inlet 61 of the bottle 60. The inner stopper 40 of the bottle 60 is fixed to the inlet 61 of the bottle 60 as shown in FIG.

After the cap assembly 1B is wound on the bottle 60, shrink wrapping is performed.

Figs. 16 and 17 are explanatory views of a scene for opening the cap first. Fig.

The consumer is handed over to the state shown in Fig.

After opening the shrink package, the consumer turns the cap 50 in the one-end closing direction. 16, the cap 50 pushes down the lid portion 42 of the inner cap 40, whereby the joint portion 421b is broken. 17, when the cap 50 is rotated in the opening direction, the cap 50 is held in the receiving portion 52 of the cap 50 while holding the lid portion 421 of the inner cap 40, Is removed. At this time, the inlet of the inner cap 40 is already opened.

8, the upper end surface 411d of the inner cap 40 which surrounds the upper opening is formed on a surface having an upward slope toward the outside. The upper face 411d of the upward slope has an effect of preventing the contents from being inadvertently dropped by improving the breaking of the contents when the bottle 60 is set up following the contents by tilting the bottle 60. [

18 is a diagram showing a change in torque when the cap 50 is rotated in the one-end closing direction in the first opening of the cap 50 in the first embodiment shown in Figs. 6 to 17. Fig. Fig. 18 is a view in comparison with Fig. 5 in the above-described comparative example.

In the case of the cap assembly 1B of the first embodiment, the peak P of the torque shown in Fig. 5 passes through when the inner cap 40 and the cap 50 are assembled, and the inner cap 40 and the cap The lid portion 421 of the inner cap 40 is located on the upper surface side of the cap 50 than the protruding portion 53 in the accommodating portion 52 of the cap 50 in a state where the cap 50 is assembled. 5 does not appear and the force (torque) for turning the cap 50 rises is that the cap 50 is held in contact with the cover portion 421 ) Is pressed. Therefore, it is not likely that the consumer who is trying to remove the cap 50 by opening the inner cap 40 misunderstands that the inner cap 40 is opened, so that the consumer is relieved and a cap assembly with good usability is realized.

Next, a cap assembly according to a second embodiment of the present invention will be described. Since the cap assembly of the second embodiment is easy to understand in comparison with the above-described comparative example, the components corresponding to the respective elements of the cap assembly 1A of the comparative example are slightly different from each other in the shape or the like, 1A to 1C (FIGS. 1 to 4), and only differences will be described.

19 is a longitudinal sectional view of a cap assembly according to a second embodiment of the present invention.

In the cap assembly 1C of the second embodiment, the cap 20 accommodates the lid portion 121 in the receiving portion 22 so that the protruding portion 23 is located below the lid portion 121, Is combined with the inner stopper (10) in a state where the portion (121) is disposed at a position with an interval between the inner surface of the outer skin (21) and the inside of the accommodating portion (22).

In order to realize this, in the case of the cap assembly 1C according to the second embodiment shown in Fig. 19, even when the lid portion 121 is accommodated above the protruding portion 23 in the accommodating portion 22, The dimensions of the accommodating portion 22 are determined so that a sufficiently wide gap is secured between the skin 21.

In order to assemble the inner cap 10 and the cap 20 in the cap assembly 1C of the second embodiment, similarly to the case of the comparative example, the inner cap 10 is filled with the contents in the bottle 30, And then the cap 20 is attached. An actual bottle 30 is used in place of the jig 70 shown in Figs. 10 to 13 in attaching the cap 20 to the worn inner cap 10, see Figs. 10 to 13 The lid portion 121 is moved to the upper surface side of the outer skin 21 beyond the protruding portion 23 in the accommodating portion 22 and then the cap 20 is rotated in the reverse direction, And the portion 121 is positioned directly above the protruding portion 23 is adopted.

19, shrink wrapping is carried out together with the bottle 30, whereby the cap 20 becomes unrotatable so that the position is fixed with respect to the inner cap 10 State.

20 and 21 are explanatory diagrams of a scene in which the cap is firstly opened in the cap assembly 1C of the second embodiment.

The hand of the consumer is handed over to the state shown in Fig.

After opening the shrink package, the consumer turns the cap 20 in the one-end closing direction. 20, the cap 20 pushes down the lid portion 12 of the inner cap 10, whereby the joint portion 121b is broken. 21, when the cap 20 is rotated in the opening direction, the cap 20 is held in the receiving portion 22 of the cap 20 while holding the lid portion 121 of the inner cap 10, Is removed. At this time, the inlet of the inner cap 10 is already opened.

In the case of the cap assembly 1C of the second embodiment as well, as in the case of the cap assembly 1B of the first embodiment described above, the peak P of the torque shown in Fig. The lid portion 121 of the inner cap 10 is inserted into the receiving portion 22 of the cap 20 while the inner cap 10 and the cap 20 are assembled together when the cap 20 is assembled, And is located on the upper surface side of the cap 20 rather than the projecting portion 23 in Fig. 5 does not appear and the force (torque) for turning the cap 20 rises is that the cap 20 is moved upward by the lid 121 ) Is pressed. Therefore, it is not likely that the consumer who is trying to remove the cap 20 by opening the inner cap 10 is mistaken for opening the inner cap 10, thereby realizing a cap assembly with good usability, which reassures the consumer.
