  The present invention relates to a capsule container that fits and hangs down at the mouth of a liquid container, a capsule in which an object to be packaged is enclosed in the capsule container, and a liquid container package with a capsule such as a PET bottle or a bottle provided with the capsule It is about.

  For example, various types of mixing containers have been proposed for storing powdered tea and drinking water separately, mixing powdered tea and drinking water at the time of eating and drinking, and providing delicious tea. .

  In the beverage mixing container of Patent Document 1, a cap body having an inner cylinder portion with a bottom lid to be inserted into the inside of a mouth portion of a PET bottle is screwed, and an element of beverage is packed in the inner cylinder portion. The cap sub-body is screwed, and during eating and drinking, the sealing ring is removed, the knob is rotated to screw the cap sub-body, and the bottom lid is pushed by the cylinder part of the cap sub-unit that descends into the inner cylinder part of the cap body. It is the structure which opens and drops the raw material of a drink.

  The beverage mixing container of Patent Document 2 is a sealed container in which powder caps are sealed with protrusions by removing the caps with protrusions facing upward, screwing the caps back onto the bottle mouths with the protrusions facing downwards It breaks the container, drops the powdered tea into the drinking water in the main body, shakes the main body, and mixes the powdered tea and the drinking water.

  The beverage mixing container of Patent Document 3 is rotated to the right while holding a cap that is non-screwed on the bottle mouth of the beverage container body during eating and drinking, and both screw portions of the cap and the bottle mouth are screwed. The cap is screwed downward, the collar member is pushed down with the cap to tear it off, and it is released from the main body. The powder tea and drinking water are mixed. The beverage mixing container of Patent Document 4 has almost the same configuration as Patent Document 3.

  Since patent document 1 accommodates the inner cylinder part of a cap main body inside the mouth part of a PET bottle, and also accommodates the cylinder part of a cap subbody inside this inner cylinder part, Since it cannot be made into the elongate accommodation space which becomes small in diameter and lengths up and down, the volume of the raw material of a drink is too small. For example, the volume of a plastic bottle is not suitable for 500 cc or more.

In each of Patent Documents 2, 3, and 4, after breaking through the enclosing container, the main body is shaken as it is to mix the powdered tea and drinking water, so that the protrusion is located in the breaking state of the enclosing container, so that the powdered tea comes out. Hard to go. After mixing powdered tea and drinking water, not only does the cap break the cap from the bottle mouth, but it is also difficult to drink without removing the cap, and it is not easy to remove the cap. Moreover, the volume of the enclosure is too small. For example, the volume of a plastic bottle is not suitable for 500 cc or more.
In Patent Document 5, the volume of the enclosure is too small. For example, the volume of a plastic bottle is not suitable for 500 cc or more. Also, it is difficult to drink.

  The present invention has been devised in view of the above-mentioned points, and can use a cap with a sealing ring that is torsionally fractured widely used at present, and is a capsule container that fits and hangs down at the mouth of a liquid container, Another object of the present invention is to provide a capsule in which an article to be packaged is enclosed in the capsule container, and a liquid container package with a capsule such as a PET bottle or a bottle provided with the capsule.

  In order to achieve the above object, the capsule container of the present invention is formed of a synthetic resin and has an opening in the lower part that communicates between the hollow part and the outside and is sealed with a lid sheet attached by heat sealing. It has an outer surface upper end portion that fits into and fits into the mouth portion of a liquid storage container such as a PET bottle or a bottle, and when the outer surface upper end portion is fitted into the mouth portion of the liquid storage container, A capsule container main body which is formed in a hollow shape having a length that hangs down to a required position inward from the mouth of the liquid container and has an engaging guide portion in the vertical direction on the outer surface portion; The capsule container body is formed of resin and is provided to be engaged and guided by the engagement guide part. The upper end of the capsule container body is placed inside a cap attached to the mouth of the capsule container body. The top And the lower end extends to a position where the opening of the capsule container main body is sealed by heat sealing and is connected by heat sealing, and the upper end is slid by applying external force to the lid sheet. And a bar to release the opening (claim 1).

  In addition, the capsule of the present invention covers the opening of the capsule container according to claim 1 with a lid sheet and heat seals to seal the opening, and connects the rolled end of the lid sheet and the lower end of the rolling bar by heat sealing. An object to be packaged such as an object to be diluted or an object to be extracted is enclosed in a hollow portion of the capsule container (Claim 2).

  Further, the capsule-equipped liquid container package of the present invention is provided at the mouth of a liquid container such as a plastic bottle or bottle that contains a solvent liquid and is sealed by attaching a cap with a sealing ring that twists and breaks the mouth. The capsule according to Item 2 is inserted, and the upper end of the outer surface of the capsule container body is retracted and fitted into the mouth, and the capsule is suspended in the liquid container (Claim 3).

  According to the capsule container having the above-described configuration, the capsule container is assembled by engaging the rolling bar with the engaging guide portion of the outer surface portion of the capsule container body, and the opening is opened by covering the opening of the capsule container with the lid sheet. The capsule having the above-described configuration can be obtained by sealing and connecting the rolled end of the lid sheet and the lower end of the rolled bar by heat sealing and enclosing the packaged object in the hollow portion of the capsule container.

  Then, the capsule having the above-described configuration is inserted into the mouth of a liquid storage container such as a plastic bottle or bottle that contains a solvent liquid and is sealed by attaching a cap with a sealing ring that twists and breaks the mouth. When the upper end of the outer surface is retracted and fitted into the mouth and the capsule is suspended in the liquid storage container, the liquid container package with a capsule having the above-described configuration can be obtained. The hollow portion of the capsule container main body can have a maximum length that hangs down to the vicinity of the bottom surface of the liquid storage container. The opening of the capsule container body is at a deep position where fingers cannot reach even if the capsule container body is short.

Therefore, the liquid container is shaken to mix the powder or liquid flowing out from the opening of the capsule container main body with the liquid in the container.

Some concentrates dilute in water, etc., and many of them lose their taste and smell over time, or decay, so a liquid container package with a capsule that stores the concentrate separately from water Is preferred. As capsules to be used for drinking, for example, green tea powder or honey, a concentrate of soft drinks, raw juice such as juice, wine, etc. are enclosed, and the liquid container is filled with water. Or about the powder etc. which melt | dissolve in water and drink, a powder can be enclosed with a capsule container and water can be stored in a liquid storage container.
However, the liquid stored in the liquid storage container is not limited to water. Moreover, the thing enclosed in a capsule is not limited to a granular material, a liquid, or food and drink.
In addition, for example, after mixing two liquids, a chemical change is promoted so that the adhesive function can be obtained only for a certain period of time.

  The capsule container and the capsule and the liquid container package with the capsule of the present invention can use a cap with a sealing ring that is torsionally fractured and is separated from the cap. By simply applying an external force to the upper end of the bar and sliding the bar, you can easily open the lid seal of the deep opening where fingers cannot reach, so the upper end of the outer surface is supported by the mouth of the liquid container. Can be sized to hang down to the bottom of the liquid storage container at the maximum, and when the capacity of the liquid storage container is large, the capacity of the capsule container can be greatly matched. It is suitable as a mixing container for storing and providing a delicious tea by mixing powdered tea and drinking water at the time of eating and drinking.

An embodiment of the present invention will be described below with reference to the drawings.
[First embodiment]

The capsule-equipped liquid container package 10 is filled with, for example, drinking water W from the mouth portion 11a of the liquid storage container 11, and the capsule 12 containing, for example, green tea powder M is inserted through the mouth portion 11a, and the upper portion of the outer surface of the capsule 12 is inserted. Is attached to the mouth portion 11a, the capsule 12 is suspended inside the liquid storage container 11, and a cap 13 with a sealing ring is attached to the mouth portion 11a. The capsule 12 is separated from the cap 13 with the sealing ring, and can have a length that hangs down to the vicinity of the bottom surface of the liquid storage container 11 at the maximum.

FIG. 2 is an assembly process diagram for explaining the capsule 12.
As shown in FIG. 2 (a), the capsule 12 includes a capsule container body 14a and a T-shaped shaped bar 14b. Here, the capsule container main body 14a and the spear bar 14b are made of PET resin in consideration of recycling. The capsule container main body 14a has a hollow portion whose horizontal section is substantially semi-cylindrical and whose upper end is closed. The lower end of the hollow portion is an opening 141. Note that the capsule 12 may be configured such that the upper end of the hollow portion is open and closed with a stopper.
The mouth portion 11 a of the liquid storage container 11 is formed such that the diameter of the inner surface upper portion 111 is, for example, 2 mm to 3 mm larger than the diameter of the inner surface lower portion 112, and the semi-cylindrical outer surface of the capsule container body 14 a is the mouth portion of the liquid storage container 11. 11a is fitted to the lower inner surface 112 of the capsule container body 14a, and the upper collar portion 148 of the outer half surface of the capsule container body 14a is fitted to the upper inner surface 111 of the mouth 11a of the liquid storage container 11. As described above, the upper portion of the outer surface of the capsule 12 is fitted into the mouth portion 11 a and the capsule 12 is suspended inside the liquid storage container 11.
The capsule 12 has an engagement guide portion 143 that is a groove having a trapezoidal cross section corresponding to the trapezoid base at the depth side at the center of the flat surface 142, and the lower end of the engagement guide portion 143 extends horizontally on the same plane. Part 144.

As shown in FIG. 2 (b), the T-shaped ruler bar 14b is formed by inserting the upper end 145a of the vertical flange portion 145 having a trapezoidal cross section from the lower end 143a of the engagement guide portion 143 of the capsule container body 14a. The lower end horizontal part 146 is stored in close contact with the thin part 144 of the capsule container body 14a so as to protrude from the upper end of the container body 14a.
Thus, the lower end surface of the capsule container main body 14a fitted with the scooping bar 14b is inclined surfaces 147 and 146a that are obtained by cutting the semi-cylinder from the flat surface 142 side obliquely downward in one plane.

FIG. 2C shows a perspective view before the capsule 12 is assembled to the liquid storage container 11. FIG.2 (d) shows the IId-IId sectional drawing in FIG.2 (c).
The capsule 12 has a configuration in which the capsule container body 14a is turned upside down and, for example, green tea powder M is filled into the hollow portion from the opening 141, and the inclined lower surface 147 is covered with a lid seal 15 having a barrier property and sealed by heat sealing. is there. The inclined upper end edge of the lid seal 15 is fixed to the inclined surface 146a of the lower end horizontal portion 146 of the T-shaped ruler bar 14b by heat sealing. Here, the lid seal 15 having a barrier property is formed by laminating a PET-G film having a heat seal property on the silica vapor deposition surface of the PET film, and the PET-G film is heat sealed to the inclined lower surface 147. PET-G is an amorphous copolyester obtained by copolymerizing terephthalic acid, ethylene glycol, and cyclohexanedimethanol, and has heat sealability.

  FIGS. 3A to 3E are explanatory diagrams of the operation of opening the capsule 12. The capsule 12 shown in FIG. 3 (a) is the same as the state shown in FIGS. 1 (a) and 2 (c). In this state, the opening 141 at the lower end of the capsule container body 14a is completely covered with the lid seal 15. Since it is closed, the drinking water W in the liquid storage container 11 cannot enter the capsule container main body 14a in FIG. That is, the drinking water W and the matcha powder M can be separated and stored.

  In FIG. 1A, when the cap 13 with a seal ring is twisted to break and remove the seal ring, the upper end of the capsule container main body 14a is retracted into the mouth portion 11a of the liquid storage container 11 and is positioned. The upper end of the bar 14b is exposed in a state of rising substantially coincident with the upper end of the mouth portion 11a.

Thus, FIGS. 3B, 3C, and 3D show a three-stage state in which the finger is placed on the upper end of the bar 14b and pushed in until it matches the upper end of the capsule container body 14a. FIG. 3E shows a perspective view corresponding to FIG.
The state shown in FIG. 3B is a state in which the lid seal 15 is peeled off from the inclined upper end of the opening 141. At this time, since the adhesion width of the lid seal 15 to the capsule container main body 14a is the largest, the peeling force is required to be the largest. be able to. As the state shifts from the state of FIG. 3B to the state of FIG. 3C to the state of FIG. 3B, the opening 141 opens widely, and the matcha tea sealed in the capsule container body 14a. The powder M easily flows out from the opening 141 and the drinking water W easily flows into the opening 141. In addition, the upper end of the bar 14b can be pushed further inward than the upper end of the capsule container main body 14a.

In this way, when the rolling bar 14b is pushed in, for example, the cap 13 is fitted again, or the mouth 11a is closed with the thumb, the liquid storage container 11 is shaken, and the drinking water W and the matcha powder M are mixed. Thus, the powdered tea M and the drinking water W are stored separately, and the powdered tea M and the drinking water W are mixed at the time of eating and drinking, so that tea with a delicious flavor can be eaten and consumed.
Since the upper end of the capsule container body 14a is retracted inward from the upper end of the liquid storage container 11, a circular space having an inner diameter of the mouth part 11a is secured in the upper part of the mouth part 11a. For this reason, at the time of eating and drinking, tea is easy to drink because an appropriate flow rate smoothly flows out of the semicircular passage in the mouth portion 11a and flows into the circular space of the mouth portion 11a.

  The capsule 22 has a capsule container main body 22a and a bar 22b. The capsule container main body 22a has a hollow part with a substantially semicircular horizontal cross section and a closed upper end. The lower end side surface of the hollow part is an opening 221, and has a trapezoidal cross section with a wide back at the center of the flat surface. It has the engagement guide part which is a groove | channel.

  The bar 22b has a trapezoidal cross-section of the flange portion inserted from the upper end of the engagement guide portion of the capsule container body 22a, and the upper end 222 of the flange portion protrudes from the upper end of the capsule container body 22a. The lower end of the lid seal 24 that is heat-sealed to the opening 221 and closes the opening 221 is bent in a U-shape, is wound around the lower end of the bar 22b, and is fixed by heat sealing on the outer surface side. Accordingly, the lid sticker 24b is slid upward and the lid seal 24 is lifted from the lower end of the lid seal 24.

In addition, the lower end of the bar 22b is made to correspond to the vicinity of the upper end of the lid seal 24, the upper end of the lid seal 24 is bent into a U shape, the lower end of the bar 22b is wound and fixed on the outer surface side by heat sealing. As described above, the lid sticker 24b can be slid downward to cover the lid seal 24 from the upper end of the lid seal 24.
The capsule-equipped liquid container package 20 is a lid that closes the opening 221 when the cap 23 with a seal ring is twisted to break and remove the seal ring and the upper end of the bar 22b is grasped and pulled out. The seal 24 is peeled off, and the matcha powder M enclosed in the capsule container main body 22a easily flows out from the opening 221 and the drinking water W easily flows into the opening 221.

In this manner, when the bar 22b is pulled out, for example, the cap 23 is fitted again or the mouth 21a is closed with the thumb, the liquid storage container 21 is shaken, and the drinking water W and the matcha powder M are mixed. Thus, the powdered tea M and the drinking water W are stored separately, and the powdered tea M and the drinking water W are mixed at the time of eating and drinking, so that tea with a delicious flavor can be eaten and consumed.
Since the upper end of the capsule container body 24a is retracted inward from the upper end of the liquid storage container 21, a circular space having an inner diameter of the mouth part 21a is secured in the upper part of the mouth part 21a. For this reason, at the time of eating and drinking, tea is easy to drink because an appropriate flow rate smoothly flows out of the semicircular passage in the mouth portion 21a and flows into the circular space of the mouth portion 21a.

The present invention is not limited to the above-described embodiment, and includes forms in which various design changes are made without departing from the scope of the invention.
