Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a multi-chamber container that separately stores and seals two or more kinds of contents having different properties such as cosmetics, daily necessities, chemicals, etc. and maintains the divided state even when pouring.

[0002]

[Prior art]

 Conventionally, as this kind of multi-chamber container, for example, the one described in Japanese Utility Model Laid-Open No. 1-96866 (Japanese Patent Application No. 62-191618) is known.

According to this conventional source, the neck portion of the inner container is passed through the neck portion of the outer container so that the neck portion of the outer container is projected from the mouth end of the outer container. A sterilized two-chamber container is shown.

In this two-chamber container, both containers are fixed by an inner stopper having a nozzle portion located above the mouth end of both containers so as to surround the upper part of the neck.

In addition, the fixing structure of the inner surface of the inner plug and the outer and inner containers suppresses the movement in the direction parallel to the axial center by hooking the flange portion of the outer and inner container into the recess of the inner plug which is provided in an annular shape. There is.

[0006]

[Problems to be solved by the device]

 However, in the conventional two-chamber container described above, the mouth end of each container is formed individually, but since the contents passing through the mouth end are mixed in the inner stopper, When resealed with a cap, the contents remaining in the inside plug will be in a mixed state.

Further, as described above, the combined structure of each container and the inner stopper is a structure in which the flange is hooked in the annular recess, so that both containers and the inner stopper are not positioned in the circumferential direction, and thus the cap is tightened. When the tip of the nozzle of the inner plug contacts the inner surface of the ceiling of the cap, and the turning power is transmitted from the inner surface of the ceiling to the inner plug, the inner plug is rotated and adheres to the inner surface of the inner plug as the inner plug rotates. The contents move and the contents are mixed.

Therefore, when the two kinds of contents are such that they chemically react, the conventional two-chamber container cannot be applied.

The present invention has been made in view of the above problems, and it is a first object of the present invention to provide a multi-chamber container that can be applied to contents that react by mixing without any trouble. And

In addition to the first object, a second object is to prevent changes in the mounting position of both containers and the inner stopper in the circumferential direction even if the caps are strongly tightened.

[0011]

[Means for Solving the Problems]

 In order to achieve the first object, the multi-chamber container according to claim 1 is composed of an outer container and an inner container, and the outer container and the inner container are combined by covering the necks of both containers with inner stoppers. In a multi-chamber container that is embodied and sealed by a cap attached to the outer container, the neck of the inner container is shaped such that it penetrates the inside of the neck of the outer container and projects from the mouth end of the outer container. The inner stopper, which is positioned in the circumferential direction and covers the neck, has a partition wall located parallel to the chord formed on the neck of the inner container, and the upper surface of the partition wall is flush with the nozzle tip. It is formed so that the lower part of the partition wall is in contact with the chord part.

In order to achieve the above-mentioned second object, in the multi-chamber container according to claim 2, in the multi-chamber container according to claim 1, a combination structure of a neck portion and an inner plug of the outer container is The structure is such that both are positioned in the circumferential direction by the unevenness provided in the direction parallel to the center.

[0013]

[Action]

 The operation of the multi-chamber container according to claim 1 will be described.

First, the neck portion of the inner container is circumferentially positioned so that the neck portion of the outer container penetrates the neck portion of the outer container and projects from the mouth end of the outer container. The displacement of the relative position to is prevented.

The inner stoppers on the necks of both containers have partition walls that are located parallel to the chords formed on the neck of the inner container, and the upper surfaces of the partition walls are flush with the nozzle tip. Since the lower part of the partition wall is brought into contact with the chord part, it is possible to secure a partition state in which the flow of the contents of the outer container and the inner container is suppressed to the nozzle tip position.

Therefore, when pouring out the contents, the contents passing through the mouth ends of the outer container and the inner container are not mixed in the inner stopper. Further, when resealing with the cap, the inner surface of the ceiling of the cap contacts the upper surface of the partition wall, which is the tip of the nozzle, so that the contents are not mixed between the inner stopper and the cap.

Further, since both containers are circumferentially positioned, the inner stopper and the inner container are circumferentially positioned by bringing the lower part of the partition wall into contact with the chord portion of the inner container, so that the inner container is positioned. The circumferential positioning of the outer container and the inner stopper is ensured via the.

Therefore, when the cap is strongly tightened, the tip of the nozzle of the inner plug comes into contact with the inner surface of the ceiling of the cap, and the rotation of the inner plug is prevented even if the rotational force is transmitted from the inner surface of the ceiling of the cap to the inner plug. , There is no mixing of the contents due to the rotation of the inner stopper.

The operation of the multi-chamber container according to claim 2 will be described.

The combination structure of the neck part and the inner plug of the outer container is a structure in which both of them are positioned in the circumferential direction by the unevenness provided in the direction parallel to the axis, so that the inner container is not interposed. The outer container and the inner stopper are firmly positioned in the circumferential direction, and the inner stopper can be reliably prevented from rotating even if a large turning force is transmitted from the inner surface of the ceiling of the cap to the inner stopper.

[0021]

It has a similar hollow shape, and communicates with a second chamber 18 that is inside the second body portion 15 below the second opening 19 of this shape.

The second neck portion 17 is composed of a chord portion 22 and a circular arc portion 23, and a second flange portion 20 and a second concave portion 21 are formed on the outer surface of the circular arc portion 23, and a semicircle of the second shoulder portion 16 is arranged from below. It is continuous with the shape part.

The chord portion 22 is a substantially vertical surface, and is continuous with the second shoulder portion 16 which is slightly outwardly spread downward.

<Structure of Inner Plug> As shown in FIGS. 3A and 3B, the inner plug 4 has a substantially cylindrical shape, and the upper portion of the side wall portion 24 becomes a tapered nozzle portion 25, Furthermore, the tip extends radially inward.

An annular first inward projection 26 is formed on the lower inner surface of the side wall portion 24, and a first inward groove 27 is formed above it.

A partition wall 30 is connected to the inner surface of the nozzle portion 25 so as to partition the inside of the nozzle portion 25 into a semicircular shape.

The upper surface of the partition wall 30 and the upper end surface of the nozzle portion 25 are formed at the same height, and the shape on the inner surface side is a thin plate-like eccentric plate 31 that hangs off the center.

Therefore, the radii from the side surface of the eccentric plate 31 to the inner surface of the nozzle portion 25 are different from each other on the right and left sides, and the second inner protruding portion 28 and the second inner protruding portion 28 are formed on the inner surface (180 ° range) of the longer distance. A groove 27 is formed.

The second inward protruding portion 28 and the second inward groove 27 are provided in the range of the forming height of the eccentric plate 31.

<Structure of Cap> As shown in FIG. 4, in the cap 5, an outer cylinder portion 35 having a diameter slightly smaller than the outer diameter of the first body portion 6 of the outer container 2 is hung from the outer periphery of the ceiling portion 34, An inner cylinder portion 36 having a female screw 37 is hung inside the outer cylinder portion 35.

A packing 38 having a desired thickness is attached to the inner surface of the ceiling portion 34 at the back of the inner tubular portion 36.

<Combination Structure of Outer Container and Inner Container> The above-described method of combining the constituent elements is such that the second neck portion 17 of the inner container 3 is inserted from the lower end opening of the first body portion 6 of the outer container 2, When the second neck portion 17 is aligned with the cutout portion 11 and penetrated, the second shoulder portion 16 on the side of the arc portion 23 comes into contact with the inner surface of the first shoulder portion 7.

At this time, as shown in FIG. 5, the second body portion 15 on the arc portion 23 side abuts the inner surface of the first body portion 6, and the second body portion 15 on the chord portion 22 side makes The inside of the body portion 6 is vertically partitioned.

Therefore, the first chamber 9 having a semicircular cross section is formed by the inner surface of the first body portion 6 and the outer surface of the second body portion 15 on the chord portion 22 side, and the second chamber 18 is formed by the inside of the second body portion 15. It is formed.

In the neck, the upper part of the second neck 17 extends above the first neck 8 and the second flange 20 and the second recess 21 are located above the end of the mouth.

In the opening of the outer container 2, the first opening 10 is formed by the chord portion 22 of the second neck portion 17 fitted in the cutout portion 11 and the mouth end of the first neck portion 8 in a direction opposite to the chord portion 22. It communicates with 1 room 9.

The mouth end of the second neck portion 17 is a second opening portion 19 having a semicircular diameter and communicates with the second chamber 18. Maintaining this state, the outer container 2 and the inner container 3 are solidified by covering the neck with an inner plug 4.

A state in which the inner plugs 4 are combined is shown in FIGS. 6 (a) and 6 (b).

According to this figure, the inner plug 4 is connected so as to cover the upper portion of the first neck portion 8, and the inside of the nozzle portion 25 communicates with the first opening portion 10 and the second opening portion 19, respectively. 32, a second pouring outlet 33 is formed.

In the combined state of the inner plug 4 and the first neck portion 8, the first inner protrusion 26 is fitted into the first recess 13 so that the first collar portion 12 is connected to the first inner protrusion 26 and the nozzle portion 25. The first flange 12 and the first inner groove 27 are annularly abutted so as to be sandwiched in the vertical direction by the base.

The combination state of the inner plug 4 and the second neck portion 17 is a state in which the second neck portion 17 penetrates the first neck portion 8 and the tip extends, and the outer diameter thereof is the first neck portion 8. Smaller diameter than. At the upper part of the second neck portion 17, the second inward protruding portion 28 is fitted in the second recessed portion 21 formed in the arc portion 22, so that the second collar portion 20 is vertically moved to the second inward protruding portion 28. The second semi-circular second flange portion 20 is in contact with the second inward groove 29 so that the second flange portion 20 is sandwiched by the tip of the nozzle portion 25.

In the chord portion 22, the tip of the second neck portion 17 contacts the inner surface of the partition wall 30, and the outer surface side thereof contacts the eccentric plate 31. That is, the second flange portion 20 and the second inner groove 29 are in contact with each other, and the inner surface of the partition wall 30 is in contact with the upper end of the chord portion 22 to prevent the positional deviation in the vertical direction. Further, the outer surface of the chord portion 22 is eccentric. The second neck portion 17 is not displaced in the radial direction due to the contact of the plate 31.

The outer container 2 and the inner container 3 are combined and fixed by the above-mentioned combination structure. Further, since the eccentric plate 31 is in contact with the outer surface of the string portion 22 and the tip of the string portion 22 is in contact with the inner surface of the partition wall 30, the contents filled in the first chamber 9 and the second chamber 18 are It is not mixed in parts.

In the combined structure of the first neck portion 8 and the second neck portion 17, the chord portion 22 is centrally arranged inside the first neck portion 8, and the eccentric plate 31 contacts the outer surface of the chord portion 22. Therefore, the eccentric eccentric plate 31 hangs down from the partition wall 30 at a position deviated from the inner center of the nozzle portion 25. This means that when the inner plug 4 is fitted, the second neck portion 17 and the inner plug 4 are combined. When the attaching position is not appropriate, the lower end of the eccentric plate 31 contacts the chord portion 22 and the inner plug 4 cannot be fitted properly.

Therefore, the eccentric plate 31 is configured not only to prevent the circulation of the contents but also to properly perform the combination work.

Even after other combinations, the upper end of the nozzle portion 25 of the inner plug 4 and the upper surface of the partition wall 30 are at the same height.

FIG. 7 shows a structure in which both containers 2 and 3 are fixed by the inner stopper 4, and then the spouts 32 and 33 are sealed by the cap 5.

A female screw 37 formed on the inner surface of the inner tubular portion 36 from the ceiling portion 34 of the cap 5 is fitted to the male screw 14 of the first neck portion 8 by the packing 38 attached to the inner surface of the ceiling portion 34. Each spout 32, 33 is sealed.

Since the nozzle portion 25 of the inner plug 4 and the partition wall 30 are flush with each other, the inner surface of the packing 38 abuts uniformly.

When the cap 5 is rotated after the inner surface of the packing 38 is lightly contacted with the nozzle portion 25, the inner plug 4 also tends to be rotated, but the chord portion 22 of the second neck portion 17 is generated. Since both ends of the eccentric plate 31 that is in contact with the inside of the nozzle portion 25 are continuous with the inner surface of the nozzle portion 25, the inner stopper 4 has a rotation resistance function. The shapes of the openings 10 and 19 are not displaced in the circumferential direction.

The outer cylinder portion 35 is formed to have an outer diameter close to that of the first body portion 6 when the cap 5 is fitted.

The two-chamber container 1 of this example has the combination structure as described above, and since the semicircular spouts 32 and 33 having substantially the same area are formed at the tip of the nozzle portion 25, the first body portion 6 is squeezed. Alternatively, when the container 1 is turned upside down, it is possible to take out substantially the same amount of the contents filled in the first chamber 9 and the second chamber 18.

In the resealing, when the cap 5 is put on the first neck portion 8 and tightened, the packing 38 attached to the inner surface of the ceiling comes into contact with the upper surfaces of the nozzle portion 25 and the partition wall 30, and the spouts 32, 2. 33 can be blocked.

Since the two-chamber container of the first embodiment has the above-described structure, (1) the separated openings 10 and 19 of the respective containers 2 and 3 are linked to the inner stopper 4 to inject the contents. It can be done in a divided state.

(2) The combination mechanism of the inner plugs 4 connects the inner and outer containers 2 and 3 and divides the inner plugs 4 by the partition wall 30 and the eccentric plate 31. The eccentric plate 31 is a chord of the inner container 3. Since it is in contact with the portion 22, the contents are not mixed in the inside plug 4.

(3) Since the eccentric plate 31 of the inner plug 4 hangs at a position deviating from the axial center, the structure is such that it can be assembled only at an appropriate position during a combining operation, and the assembling work is easy.

(4) Since the eccentric plate 31 is brought into contact with the chord portion 22 of the inner container 3, even when the cap 5 is tightened, the mounting position of the inner plug 4 in the circumferential direction does not change.

In the above-mentioned contents taking-out operation and the re-sealing operation of the cap 5, since the mixing of two kinds of contents is prevented, it is most suitable to be applied as a container of contents which react by mixing. A two-chamber container can be provided.

Second Embodiment A second embodiment corresponding to claim 2 provides a structure in which the circumferential positioning of the inner plug 4 with respect to the outer container 2 is not impaired.

8A and 8B show the outer container 2 of this example.

The outer container 2 of the second embodiment is different from the first embodiment only in that a vertical groove 39 is formed in the direction opposite to the first flange portion 12.

The vertical groove 39 is formed by notching the middle of the cutout portion 11 and the first flange portion 12 in the facing direction in a vertical concave shape so that the depth thereof is flush with the first concave portion 13. Is formed.

9A and 9B show the structure of the inner plug 4.

The inner plug 4 of the second embodiment is different from the first embodiment only in that the protrusion 40 is provided on the inner surface side of the side wall portion 24 in the facing direction.

The protrusion 40 is provided so as to extend from the first inward groove 27 in the direction orthogonal to the partition wall 30 to the lower portion of the first inward protruding portion 26, and the width and the degree of protrusion fit into the vertical groove 39. It has a shape that allows it.

FIG. 10 shows a state in which the inner plug 4 is fitted over the first neck portion 8 of the outer container 2.

The first inward projection 26 and the first inward groove 27 (not shown) formed on the inner side of the side wall 24 of the inner plug 4 are fitted in the same manner as in the first embodiment. There is.

In addition to this situation, the projection 40 projecting in the direction orthogonal to the partition wall 30 is fitted into the vertical groove 39 of the first neck portion 8 and its side surfaces are in contact with each other.

Therefore, the first neck 8 is fixed axially by assembling the first inward projection 26 and the first inner groove 27, and the inner stopper 4 is fixed circumferentially by the vertical groove. This is done by assembling 39 and the protrusion 40.

The assembling situation of the inner container 3 and the inner stopper 4 is the same as that of the first embodiment.

With the above-described configuration, even if the cap 5 is tightly fitted and the inner plug 4 is rotated while being pushed, the positional displacement of the inner plug 4 in the circumferential direction does not occur. Also, even if there is play in the circumferential direction in the penetrating state of the cutout portion 11 of the first neck portion 8 and the second neck portion 17, since the inner plug 4 is not fixed in combination with the second neck portion 17, the same applies. For this reason, even if a clearance is provided to facilitate the penetration of the second neck portion 17, it does not affect the positioning performance of the inner plug 4.

In order to easily fit the protrusion 40 into the vertical groove 39, the protrusion 40 is provided below the second inward protrusion portion 28, and the shape of the lower portion thereof is slightly thinner than that of the upper portion.

As in the first embodiment, when the two are combined, the eccentric plate 31 of the partition wall 30 contacts the chord portion 22 of the second neck portion 17.

Since the two-chamber container of the second embodiment has the above-mentioned structure, in addition to the effects of (1), (2) and (3) in the first embodiment, (4 ') outside Since the container 3 and the inner plug 4 are positioned in the circumferential direction by the concave and convex fitting by the vertical groove 39 and the projection 40, even if the cap 5 is strongly tightened, the change in the mounting position of the inner plug 4 in the circumferential direction is surely performed. Can be prevented.

Although the embodiment has been described above with reference to the drawings, the specific configuration is not limited to this embodiment, and the present invention can be made even if the configuration is changed or added without departing from the scope of the present invention. include.

For example, although an example of a two-chamber container is shown as a multi-chamber container, a three-chamber container having two inner containers may be used.
