A two-liquid storage container in which the container main body and the inner container are sealed by screwing them together, the lower end edge of the skirt portion of the inner container being separated from the outer peripheral wall of the container main body, and the upper lid skirt This is achieved by a container characterized in that it has an outer diameter larger than the diameter of an imaginary circle formed by the inner end of the protrusion of the upper lid skirt and is located above the upper end of the protrusion of the upper lid skirt.

The present invention will be explained in more detail below with reference to the drawings.

In the container of the present invention shown in FIG. 1, reference numeral 1 denotes a bottomed cylindrical container body made of glass, synthetic resin, etc., which has a beaded edge 1a at the opening 23 and contains a first liquid A (for example, mineral water). , juice, etc.). 2 is a bottomed inner container made of a thin metal plate made of aluminum alloy, tinplate, tin-free steel, etc., synthetic resin, or a laminate thereof, and contains a second liquid B (e.g., whiskey, brandy).

A cup-shaped liquid storage part 3 that stores liquid (shochu, etc.) and is tapered toward the bottom, a flange part 4 that extends diametrically outward from the entire periphery of the upper end of the storage part 3, and the flange It consists of a skirt part 5 extending downward from the periphery of the part 4. The accommodating part 3 is inserted into the opening 23 of the container body 1, the flange part 4 is placed on the upper end 24 of the container body 1, and the middle part of the skirt part 5 is crimped with a crimper or the like.
The container body 1 is sealed by the accommodating part 3 and the flange part 4 by bending it inward along the lower surface of the container part a (the skirt part may be formed into this shape in advance). In order to improve sealing performance, the flange portion 4 of the inner container and the container body 1 are
It is desirable that an appropriate sealing material 7 be provided between the upper end surface of the holder and the upper end surface of the holder.

In addition, instead of the sealing material 7, it is possible to use a material that does not adversely affect the aroma of the contents and is easy to unseal (peel off) when the container body 1 is opened.
Adhesives that can be used may also be used.

As shown in FIG. 2, the skirt portion 5 is preferably provided with a plurality of slits 18 extending upward from the lower end of the skirt.

This skirt portion 5, as shown in FIGS. 1 and 4,
The lower end edge 5a is separated from the outer circumferential wall of the container body 1 and protrudes outward, but since it is provided with the suline 1-18, it easily becomes elastic in the direction of the arrow X (Fig. 4) when an external force is applied. It can be transformed into.

The opening of the inner container 2 is connected to the flange of the inner container 2 by an annular sealing material 21 provided on the inner surface of the top 25 of the highly flexible upper lid 8 made of a thin metal plate such as aluminum alloy, tinplate, or tin-free steel. It is sealed by bringing it into close contact with 4.

A protrusion 9 extending downward is provided at the center of the upper lid 8, and its tip reaches near the bottom wall 3a of the accommodating portion 3.

The protrusion 9 is preferably made of a synthetic resin material, has a substantially conical shape, and needs to have high structural rigidity.

The upper cover 8 is provided with a wave-shaped ring so that it can be largely deformed when a pressing force is applied to move the protrusion 9 downward.

As shown in FIG. 3, the bottom wall 3a is provided with a planned opening part 2 surrounded by a score line 11 so that the bottom wall 3a is easily broken and an opening is formed by pushing down the protrusion 9. .

This score line 11 is a notch, that is, a thin portion that does not pass through.

13 is a recess provided inside the planned opening portion 12;
This is to ensure that the tip of the pushed-down protrusion 9 is received, to prevent lateral displacement, and to effectively break the score line.

As shown in FIG. 4, the upper lid 8 has an outer circumferential edge of its top portion 25 that extends beyond the flange portion 4 of the inner container 2, and a side wall that extends downward from the outer circumferential edge and covers the upper outer circumferential wall 1b of the container body 1. It has a skirt portion 8a that forms a skirt portion 8a. As shown in FIG. 5, the lower end edge of the skirt portion 8a is deeply bent inward at predetermined intervals to form an appropriate number of protrusions 8b.

As shown in FIG. 4, the diameter d of the virtual circle formed by the inner ends of the projections 8b, 8b, 8b when the container body 1 and the inner container 2 are sealed is the lower edge of the skirt portion of the inner container. 5
The length hl from the upper end of the skirt portion 8a to the projection 8b must be longer than the length h2 of the skirt portion 5 of the inner container 2. (Strictly speaking, 1, it is necessary that the lower edge 5a is located above the upper end of the protrusion 8b.)

As shown in FIG. 6, on the upper outer peripheral wall 1b of the container body,
A helical thread 20 is provided. The threads 20 are a plurality of threads arranged discontinuously, and the distance between the starting ends of the adjacent threads 20, 20 is equal to the center of the adjacent protrusions 8b, 8b of the skirt portion 8a of the upper lid. It corresponds to the interval between. The height position at which this screw thread 20 is installed is such that when the upper lid 8 is mounted on the container body 1 from above the inner container 2 inserted and placed on the container body 1 and rotated, the protruding portion 8b is arranged to engage the lower surface of the thread 20 to produce a threaded effect.

Note that the container body 1 may be made of ceramic or metal in addition to those made of the exemplified materials. In addition, on the inner surface of the metal container main body 1, on both the inner and outer surfaces of the metal inner container 2, and on the inner surface of the metal upper M8,
Preferably, a protective coating is applied.

An example of assembling this two-liquid inner container will be described below.

First, the first liquid A (for example, mineral water) is hot-filled into the container body 1, and then the accommodating portion 3 of the inner container is inserted into the opening 23 of the container body, and the flange portion 4 is inserted onto the upper end 24. After being placed on the container body 1, the skirt portion 5 is bent inward using a crimper along the lower surface of the beaded edge 1a to seal the opening 23 of the container body 1. Thereafter, the container body 1 is turned over, the outer surface of the inner container 2 is sterilized by the heat of the first liquid A, and after cooling, the container body 1 is erected, and the second liquid is placed in the storage part 3 of the inner container. Fill with liquid B (e.g. whiskey),
Next, place the upper M8 over the opening 23 of the container body from above the inner container 2 with the tip side of the protrusion 9 facing downward, and rotate the upper lid 8 in the same direction as the clock hands when viewed from above. By doing so, the protrusion 8b of the skirt portion and the thread 2 of the container body are
Finally, the inner container 2 is sealed by bringing the annular sealing material 21 on the inner surface of the top portion 25 of the upper lid into pressure contact with the upper surface of the flange portion 4 of the inner container.

When the upper lid 8 is mounted, the projection 8b of the upper M8 comes into contact with the lower edge 5a of the skirt 5 of the inner container 2, which has a larger diameter, and elastically deforms it in the direction of the arrow X in FIG. However, if the slit 18 is provided in the skirt portion 5 as described above, the inner container 2 can be easily deformed even if it is manufactured from a thin metal plate. Next, the upper cover 8 is rotated a little as necessary to allow the protrusion 8b to pass downward between the screw threads 20.

Furthermore, when the upper M8 is rotated as described above, the projection 8b of the upper cover 8 continues to descend while contacting the lower surface of the screw thread 20, but the annular sealing material 2 provided on the inner surface of the top portion 25 of the upper II8
1 and the upper surface of the flange portion 4 of the inner container 2 come into pressure contact, the lowering stops, and at this time, a seal between the inner container 2 and the upper lid 8 is obtained.

The two-liquid storage container is now assembled.

In this example, the first liquid A was filled by the hot filling method, but the container body and the inner container were sterilized in advance, and after sterilization, the cooled liquid was filled and sealed in a sterile atmosphere. When using an aseptic filling method, when post-sterilizing, or when using a liquid that does not require sterilization as the first liquid A (for example, whiskey,
brandy.

gin, etc.), a cold filling method can be used.

Although not shown in the figure, in order to prevent consumers from pushing the top lid of the two-component storage container downwards on the store display shelf and breaking the bottom wall of the inner container (mischief prevention), the ):
It is desirable to take appropriate measures such as covering the entire lid with a shrink film or placing a cover plate over the top lid that covers at least the center portion of the top lid.

When drinking the liquid content, if the upper I8 is covered with a shrink film or the like, first remove it, and then press down the center of the upper M8 with your finger to remove the protrusion 9.
is moved downward to break the bottom wall 3a of the inner container 2.

By this operation, the second liquid B contained in the inner container 2 flows down into the container body 1 and mixes with the first liquid A contained therein.

When the top lid is rotated in the opposite direction to the above-mentioned direction, the threaded engagement between the projection 8b of the top lid and the screw thread 20 of the container body is released.
Next, when the upper M8 is pulled up, the projection 8b catches the lower edge 5a of the skirt of the inner container and elastically deforms it in the direction opposite to the arrow X in FIG. 4, so that the flange 4 and bead 1a are The tight engagement is released and the inner container 2 can be removed together with the top cover 8 very easily.

You drink the mixed liquid directly from the container body 1, but if you want to store it again without drinking it all or change the drinking location, you can remove the upper lid 8 while holding the inner container 2 so that the accommodating part 3 of the inner container is It is placed over the container body 1 so as to be inserted into the opening 23 of the container body, and rotated in the same direction as the clock hands to screw the protrusion 8b and threaded thread 20 together to reseal the container.

As a result, close engagement is formed and maintained between the lower surface of the flange portion 4 of the inner container and the upper end 24 of the container body, and between the lower surface of the top portion 25 of the upper lid and the upper surface of the flange portion 4. The inner container will not leak even if it is knocked over or turned upside down. Furthermore, when resealing the package, the same operation as when opening the package is required.

Furthermore, when the top lid 8 is removed from the container body 1, the entire inner container 2 is also removed from the container body 1.
You can drink the whole thing without leaving any liquid inside.

For example, if liquid A is mineral water and liquid B is whiskey, you can easily make shochu with water, and if liquid A is lemon water and liquid B is shochu, you can easily make shochu with lemon water. It can be used as a tablet and can be re-stored, making it extremely convenient for portable use.

In addition, in the two-component storage container of the type shown in FIG. 8, in order to maintain liquid tightness during transportation and long-term storage, the adhesive strength between the flange portion 4 of the inner container 102 and the upper portion 11108 is increased. It is necessary to bond with a strong adhesive 130 that does not deteriorate over time, and if such an adhesive is used, the volatile components of the solvent contained in the adhesive may cause the content to deteriorate slightly. (Especially when Liquid B is whiskey, brandy, etc.)
Moreover, this tendency is strong when the adhesive is subjected to heat treatment. ) However, in the two-liquid storage container of the present invention, it is possible to completely seal the inner container and the top lid without using an adhesive, so it is effective in retaining the scent of the inner container.

In the above explanation, the planned opening portion 12 surrounded by the score line 11 was provided on the bottom wall 3a of the inner container;
If the bottom wall 3a is made of a thin (and easily breakable) material, score!i#!11 may be omitted.

In addition, the upper cover 8 excluding the protrusion 9 is not only molded from an integral thin metal plate, but also has a disk-shaped central portion 26 made of synthetic resin or a thin metal plate, as shown in FIG. an annular top portion 27 that contacts the outer peripheral portion 26a of the central portion 26; and a skirt portion 8 that extends downward from the annular top portion 27.
It is also possible to construct the annular peripheral portion 28 consisting of three parts by molding it from a metal plate or a hard synthetic resin.

Furthermore, the central portion 26 and the annular peripheral portion 28 may be integrally molded from synthetic resin. When at least the central portion is molded from synthetic resin, it may be integrally molded with the protrusion.

In addition, the inner container 2 may be formed of a single material of synthetic resin such as polyester or polyethylene polypropylene, or a multilayer structure including a synthetic resin layer with excellent gas barrier properties, or a multilayer structure of a metal foil layer and a synthetic resin layer. In this case, the bottom wall 3
If a is thin, the bottom wall 3a can be broken with the tip of a needle or a small force, so the protrusion 9 of the top cover 8 may be omitted.

Furthermore, in the container body 1 described above, the bead 1a is used to maintain the seal with the inner container 2 by mechanical engagement between the skirt portion 5 of the inner container 2 and the upper outer circumferential wall of the container body 1. However, this retention is sufficient if it is maintained until the top lid 8 is screwed onto the container body, so an adhesive that maintains strong adhesive force for only a short period of time is used in the container without adversely affecting the aroma of the liquid inside. By interposing it between the upper end 24 of the main body and the lower surface of the flange portion 4 of the inner container, it is possible to use a container main body 1 without a beaded edge 1a, and there is no need to caulk the skirt portion 5 of the inner container.

〔Example〕

Example 1 As shown in FIG. 6, the container body 1 is a bottomed cylindrical container made of glass and has a screw thread 20 on the upper outer circumferential wall.

The inner container 2 is an aluminum alloy thin plate type, and as shown in FIGS. 2 and 3, it has a cup-shaped storage portion 3, a flange portion 4 extending outward from the outer periphery of its upper end, and a flange portion 4 extending outward from the outer periphery of its upper end. It consists of a skirt part 5 that hangs down a short distance from the circumference and then extends diagonally outward, and the skirt part 5 includes:
A number of sulins (18) extending upward from the lower end are provided;
The bottom wall 3a has a planned opening portion 12 surrounded by a score line 11.
and a recess 13 is provided inside thereof.

The inner container 2 is coated with a vinyl organosol paint on both its inner and outer surfaces, and a polyester resin sealant 7 is coated on the lower surface of the flange portion 4.

The top lid 8 is made of tin plate, and as shown in FIGS. 1 and 5, a circular top portion 25 having a wave-shaped ring and a base portion of a protruding portion 9 made of polyester resin that is separately injection molded are fitted into the top lid 8. The fitting part 29, which extends downward from the entire outer edge of the top part 25 and has a longer length than the skirt part 5 of the inner container, and the lower end thereof are inwardly The inner surface is coated with a vinyl organosol paint, the outer surface is coated with a vinyl chloride-vinyl acetate copolymer paint, and the top part 2 is bent and protrudes inward.
A polyester resin sealing material 21 is placed on the inner surface of the outer periphery of 5.
is applied in a ring shape.

After filling this container body with mineral water heated to approximately 95°C, the accommodating portion 3 of the inner container described above is inserted into the opening 23 of the container body, and the flange portion 4 is placed on the upper end 24 of the container body. Opening 2 of the container body
3 was sealed, and the skirt portion 5 was bent inward using a crimper along the lower surface of the beaded edge 1a of the container body to seal the opening 23 of the container body.

Next, the container body 1 is inverted, held for about 1 minute, and then cooled with cold water to lower the liquid temperature to 30 to 40°C. After the container body 1 is stood upright, the storage part 3 of the inner container is filled with whiskey.

Then, when the above-mentioned upper lid 8 is placed over the container body 1 and the inner container 2 with the tip side of the protrusion 9 facing down and rotated in the direction of rotation of the clock hands, the upper lid protrusion 8b and the container body are rotated. The threads 20 began to screw together, and finally, the top 25 of the upper lid and the flange 4 of the inner container came into pressure contact via the sealing material 21, and the inner container 2 was sealed.

In this example, since a wave-shaped ring is provided on the top 25 of the upper lid,
It is possible to push down the protrusion 9 even with a relatively small force,
In addition, the bottom wall 3a of the inner container at the portion facing the tip of the protrusion 9
Since a concave portion 13 is provided in the bottom wall 3a and a scheduled opening portion 12 is formed by the score line 11 surrounding the concave portion 13, the bottom wall 3a
Breaking is easy and reliable.

Furthermore, by simply rotating and lifting the upper M8 in the opposite direction to the direction used when sealing, the lower edge 5a of the skirt portion of the inner container is aligned with the three protrusions 8b, 8b of the skirt portion of the upper lid.

8b, the inner container 2 can be removed from the main container body 1 together with the upper M8.

Therefore, you can drink the whiskey with water directly from the container body 1, and if there is any leftover drink, place the top lid 8 holding the inner container 2 over the opening 23 of the container body and then rotate it. Since the protrusion 8b and the screw thread 20 are screwed together with just one step, resealing can be easily performed.

Moreover, since the inner container 2 is completely removed from the container body 1, it does not get in the way when drinking the liquid content, and moreover, the liquid content in the container body 1 can be drunk without leaving any residue.

Example 2 In this example, the container body 1 and the inner container 2 used in Example 1 were used, and only the upper lid 8 had the shape shown in FIG. 7.

That is, a disk-shaped central portion 2 having a fitting portion 29 in the central portion
6 is pressure-formed from a polyester resin sheet, and the base of a separately injection-molded polyester resin protrusion 9 is fitted and locked into the cavity of the fitting part 29 in the center, while the inner and outer surfaces are chlorinated. <A ring-shaped top part 27, a skirt part 8a extending downward from the annular top part 27, and a protrusion part 8b protruding inward by bending several parts of the lower end part inward are made from a tin plate coated with a Nyl-vinyl acetate copolymer paint. An annular peripheral portion 28 was formed, and the annular top portion 27 and the outer peripheral portion 26a of the central portion were joined using a polyester resin adhesive to complete the upper M8.

Then, in the same procedure as in Example 1, the container body 1 is hot filled with mineral water, and the opening 23 is filled with the inner container 2.
After sealing, the container body 1 is inverted, the inner container 2 is sterilized and cooled with water, and then the container body 1 is stood upright, and the inner container 2 is filled with whiskey. As shown,
Place the assembled upper M8 over the inner container 2 and container body 1,
The upper lid 8 is rotated in the same direction as the clock hands to screw the protrusion 8b and the thread 20 together, and the center portion 26 is inserted between the annular top portion 27 of the annular peripheral portion 28 and the flange portion 4 of the inner container 2. The inner container 3 was sealed by pinching and holding the outer peripheral portion 26a.

In this example, since the central portion 26 of the upper lid 8 is molded from a polyester resin with excellent flexibility, less force is required to push down the protrusion 9, and therefore the inner container 26 is lower than in the first embodiment. The bottom wall 3a was easily broken.

On the other hand, since the annular peripheral edge portion 28 of the top lid 8 is formed from a gold N plate, the protrusion 8b and the thread 20 of the container body 1 can be firmly screwed together. It is reliable to maintain, and easy to open (including resealing) and reseal.

〔Effect of the invention〕

As detailed above, according to the two-liquid storage container of the present invention,
Due to the threaded engagement between the protrusion provided on the top lid and the screw thread provided on the container body, there is a gap between the inner surface of the top lid, which is a sealing surface, and the top surface of the flange of the inner container, and between the bottom surface of the flange of the inner container and the top of the container body. Since close contact can be made between the container and the end surface, the sealing performance of the entire container can be maintained reliably, and even after the container has been opened, it can be resealed easily and reliably, so the content liquid can be reliably preserved. It is especially convenient to carry when traveling.
