The PET bottle has good convenience that the drink can be taken immediately after removing the cap, but the cartridges disclosed in Patent Document 1 and Patent Document 2 completely block the drinking mouth. Therefore, when drinking the contents, the cartridge must be once removed from the drinking mouth, which is cumbersome and the water adhering to the tea leaves or the cartridge may sag, resulting in some inconvenience in terms of usability.
On the other hand, since the simple lantern disclosed in Patent Document 3 is designed to attach the lighting device using the screw groove on the outer periphery of the drinking mouth, the cap is different when using the plastic bottle as a simple lantern. There is a problem that a cap cannot be prepared immediately when it is necessary to store the same in a place and the same plastic bottle is to be reused as a beverage container.
The present invention provides a cartridge for a plastic bottle that can solve at least one of the aforementioned problems.

The present invention is a plastic bottle cartridge to be attached to a drinking mouth of a plastic bottle with a cap, and is provided at the upper end of the hollow cartridge main body portion inserted into the inside of the plastic bottle from the drinking mouth. A stopper portion that interferes with the drinking mouth when the cartridge main body portion is inserted into the PET bottle, and the cartridge body portion has an outer periphery that closely contacts the inner circumferential surface of the drinking mouth. A cartridge for a plastic bottle provided on the surface is provided.

The stopper portion has a function of locking the drinking bottle so that the PET bottle cartridge does not fall into the PET bottle. The shape of the stopper part is not limited to a specific one, but if it has a circular shape that is larger than the inner diameter of the drinking mouth and smaller than or equal to the outer diameter, the stopper function can be sufficiently exerted, and the cap It is not an obstacle when opening and closing. The close contact portion has a function of securing water tightness so that the contents are not spilled even when the plastic bottle is tilted, and a function of fixing the plastic bottle cartridge so as not to be detached from the plastic bottle.

The cartridge for a plastic bottle of the present invention is characterized in that the cartridge main body has a side wall in which holes for allowing the tea leaf components stored in the hollow interior to ooze into the liquid filled in the plastic bottle, The liquid can be configured to have an upper wall in which holes for allowing the liquid to flow out of the drinking mouth are formed.

This PET bottle cartridge allows tea leaf exudate to flow out from the hole in the upper wall while attached to the PET bottle, so that the drinker can drink tea leaf exudate without removing the PET bottle cartridge. it can. Since the PET bottle cartridge and the drinking mouth are watertight due to the close contact portion, even when the PET bottle is tilted during drinking, the tea leaf exudate does not spill out from other than the hole.

The cartridge for a plastic bottle of the present invention controls the light emitting means, the power supply for supplying power to the light emitting means, and the energization and the electric shielding to the light emitting means in the hollow interior where the cartridge main body is watertight. A lighting device including a magnetic switch can be provided.

This plastic bottle cartridge employs a magnetic switch so as to ensure water tightness, and can be controlled by applying a magnetic force from the outside of the plastic bottle in a state of being attached to the plastic bottle. You can enjoy changes in the refractive index and color of light by changing the type and color of the liquid that fills the PET bottle. Moreover, if a drinkable liquid is filled, the throat can be moisturized by removing the PET bottle cartridge and drinking the liquid.

If you use a cartridge for PET bottles with tea leaves stored in the cartridge body, you can easily make green tea or black tea, and you can drink it without removing the PET bottle cartridge. It can be reused as a beverage container without sacrificing convenience.
Moreover, if it uses in the aspect which accommodated the illuminating device, it can be reused as a simple lantern which utilized the outstanding design nature which a PET bottle has.

First, the structure of a tea strainer cartridge which is a first embodiment of a plastic bottle cartridge will be described with reference to FIGS. The tea strainer cartridge 10 includes a cartridge body 12 and a stopper 14. The cartridge main body 12 includes a circular upper wall 16 and a lower wall 18 and a cylindrical side wall 20, and a storage space 22 is formed in a hollow interior surrounded by these walls. The side wall 20 is vertically divided at the position of the separation line 24. The concave and convex portions 26 formed at the lower portion of the upper side wall 20 and the convex portions 28 formed at the upper portion of the lower side wall 20 are engaged with each other to connect the upper and lower side walls 20 and close the storage space 22. When the engagement between the concave portion 26 and the convex portion 28 is released, the side wall 20 is vertically separated at the position of the separation line 24, and the storage space 22 is opened.

The side wall 20 is provided with a plurality of holes 30 penetrating inward and outward. The upper wall 16 is also provided with a similar hole 32. These holes 30 and 32 are provided with the same size and interval as the tea strainer holes provided in a common teapot. The upper portion of the side wall 20 is a close contact portion 34 having a larger outer diameter than other portions. The close contact portion 34 is in close contact with the inner peripheral surface 44 of the drinking mouth 42 when the tea strainer cartridge 10 is mounted on the plastic bottle 40.

A circular stopper portion 14 is provided at the upper end of the side wall 20 so as to project in a bowl shape. The diameter of the stopper portion 14 is larger than the inner diameter of the drinking mouth 42 and smaller than the inner diameter of the cap 46. For this reason, when the tea strainer cartridge 10 is attached to the plastic bottle 40, the stopper portion 14 interferes with the drinking mouth 42, so that the tea strainer cartridge 10 does not fall into the plastic bottle 40. Further, the cap 46 can be closed even when the tea strainer cartridge 10 is mounted on the plastic bottle 40. However, if the stopper portion 14 is too thick, the cap 46 is not easily closed, so it is necessary to make it as thin as possible.

Next, a method for using the tea strainer cartridge 10 will be described with reference to FIG. The tea strainer cartridge 10 is suitable for the exudation of various tea leaves such as green tea and black tea and coarsely ground coffee beans. Here, the tea leaves 48 of green tea are filled in the storage space 22. The tea leaves 48 can be easily filled by dividing the tea strainer cartridge 10 into upper and lower parts. The tea strainer cartridge 10 filled with the tea leaves 48 is attached to a plastic bottle 40 filled with water. The water that has entered the storage space 22 through the hole 30 provided in the side wall 20 soaks the tea leaf 48, and the component exuded from the tea leaf 48 spreads into the plastic bottle 40 through the hole 30, thereby producing green tea. Depending on the type of tea leaves 48, it may be better to fill with hot water instead of water.

When you drink green tea, you can pour it into a cup, or put it directly on the drinking mouth 42 and drink it. The tea leaves 48 are blocked by the upper wall 16 of the tea strainer cartridge 10, and only green tea flows out from the holes 32. Even if the tea bottle cartridge 10 is tilted, the tea strainer cartridge 10 is not displaced or detached, and can be used to drink green tea.

Next, the structure of the LED cartridge which is 2nd Embodiment of the cartridge for PET bottles is demonstrated with reference to FIG. The LED cartridge 50 includes a cartridge main body 52 and a stopper 54 as in the tea strainer cartridge 10. Of these, the stopper portion 54 has the same structure as the stopper portion 14 of the tea strainer cartridge 10. The cartridge main body 52 includes a circular upper wall 56, a lower wall 58, and a cylindrical side wall 60, and a storage space 62 is formed on the inner side surrounded by these walls. Unlike the tea strainer cartridge 10, the upper wall 56 and the side wall 60 are not provided with holes, and the storage space 62 is formed watertight.

The storage space 62 stores an LED 64, a battery 66 as a power source of the LED 64, and a magnetic switch 68 that controls energization and power shielding from the battery 66 to the LED 64. The LED 64 is housed inside a waterproof cover 70 provided so as to protrude downward from the lower wall 58. The magnetic switch 68 is disposed so as to be the same height as the lower part of the drinking mouth 42 when the LED cartridge 50 is attached to the plastic bottle 40. Moreover, it arrange | positions in the position eccentric from the center of the cross section of the drinking mouth 42. FIG.

Next, a simple lantern using the LED cartridge 50 will be described with reference to FIGS. A simple lantern 80 is obtained by mounting an LED cartridge 50 on a plastic bottle 40. Here, a detachable tea strainer cartridge 82 is attached to the lower part of the LED cartridge 50. The tea strainer cartridge 82 can be selectively mounted when the PET bottle 40 is used not only as a simple lantern but also as a beverage container.

The magnetic switch 68 detects a change in magnetic force by a built-in magnetic sensor and performs power ON / OFF control. A magnetic lever 84 is attached to the outer periphery of the portion below the drinking mouth 42 of the PET bottle 40. The magnetic lever 84 includes an arc-shaped portion 86 and an annular portion 88, and a magnet 90 is attached to a connecting portion between the arc-shaped portion 86 and the annular portion 88. The arc-shaped portion 86 is attached so as to grip the outer periphery of the drinking mouth 42. The annular portion 88 can hold the cap 46 removed from the plastic bottle 40 by fitting. The magnetic lever 84 is rotatable about the drinking mouth 42, and the position of the magnet 90 can be changed depending on the rotation position. When the magnet 90 is near the magnetic switch 68 as shown in FIG. 7a, the magnetic switch 68 performs power-on control, and the LED is lit. When the magnetic switch 68 is away from the magnetic switch 68 as shown in FIGS. 7b and 7c, the magnetic switch 68 performs power-off control, and the LED is turned off.

The PET bottle 40 is filled with green tea that has exuded from the tea leaves 92 accommodated in the tea strainer cartridge 82, and can be used as a simple lantern 80 illuminated by the vivid green of green tea when the LED is turned on. For example, if the simple lantern 80 is placed on a bedside or the like, it is very convenient for performing simple work by illuminating the hand after the light is turned off, and the throat can be moistened with green tea.
