  Embodiments of a plastic bottle provided with a packaging bag with a replacement cap according to the present invention will be described below with reference to the accompanying drawings.

  First, the outline of the plastic bottle with a replacement cap according to the first embodiment will be described with reference to FIGS. 1 and 2. 1 and 2 are diagrams for explaining an outline of a plastic bottle with a replacement cap according to the first embodiment.

  As shown in FIG. 1, the plastic bottle 1 with a replacement cap includes a plastic bottle 10 and a packaging bag 20 with a replacement cap. The mouth part of the PET bottle 10 is sealed with a cap, and the tea powder 45 contained in the cap falls to the surface of the drinking water in the PET bottle 10 by a predetermined operation of loosening and opening the cap when drinking. The structure is mixed. The packaging bag 20 with a replacement cap includes three replacement caps that are the same as the cap described above, and is suspended from the bottle neck 13 of the plastic bottle 10. The cap attached to the plastic bottle 10 from the beginning and each of the three replacement caps contain the same powdered green tea or tea powders of different tea production areas such as Shizuoka, Uji, and Ise.

  A purchaser of such a PET bottle 10 first makes tea by dropping the tea powder 45 built in the cap into the drinking water 11 in the PET bottle 10 by a predetermined operation and mixing the tea powder and the drinking water. be able to.

  After drinking tea, as shown in FIG. 2, the purchaser cleans the plastic bottle 10 and puts drinking water 11 into the plastic bottle 10. The used cap may be used to seal the bottle opening 10a in order to rinse the inside of the PET bottle 10 at the time of washing, but may be basically disposed of.

  Then, the purchaser takes out one replacement cap from the replacement cap-containing packaging bag 20 and attaches it to the bottle port 10a of the plastic bottle 10 by screwing. As described above, the replacement cap 12 has the same structure as the cap originally attached to the plastic bottle 10. In other words, the purchaser uses the same plastic bottle 10 and selects one of the replacement caps 40 attached to the plastic bottle 10 and attaches it to the screw to make a plastic bottle with tea again. Can do. Similarly, after the first drink, the purchaser can make a plastic bottle with tea many times using the second and third replacement caps 40. The tea powder 45 contained in the replacement cap 40 is filled with the same one, the filling amount is changed so that the strength can be selected, the ones of different origins are filled, or different beverages. The powder for use may be filled.

  Originally, PET bottles were disposable. In other words, conventionally, when a purchaser purchases the second and third cups of tea using a plastic bottle, a new plastic bottle is used and the used plastic bottle is discarded.

  However, in the case of the plastic bottle 1 with a replacement cap, when the purchaser purchases up to the second and third cups of tea, the same PET bottle 10 is used for the second and subsequent cups of tea. The bottle 10 can be reused. Therefore, it is possible to reduce the disposable use of PET bottles and to have an effect on environmental measures. Also, for example, if you sell PET bottles 1 with replacement caps at a price of 300 yen, 4 cups of tea from various production areas will be as low as 75 yen per cup (currently 120 yen per cup). The tea can be provided reasonably to the purchaser. The replacement cap is not limited to the PET bottle 10 and has versatility that can be used with any PET bottle as long as it is a general standard PET bottle.

  Next, the components of the plastic bottle 1 with a replacement cap will be specifically described with reference to FIGS. FIG. 3 is a diagram illustrating the packaging bag itself of the packaging bag 20 with the replacement cap. As shown in FIG. 3, the packaging bag 30 includes three storage portions 31 to 33 and an extension portion 34, and the storage portions 31 to 33 represent the opening portion 31 a and the folded portion 31 b (representing the storage portion 31). The extension 34 has a hole 34a and a hooking hole 34b.

  The storage parts 31 to 33 are formed by combining two transparent films of a substantially rectangular shape, bonding by heat sealing or the like on the three sides of the two combined films, and not bonding the remaining one side. Keep. Thus, since the accommodating parts 31-33 are transparent bag shape, it is easy to confirm what exchange cap is contained in them. For example, by indicating the tea production area on the replacement cap itself, the purchaser can select the tea that he wants to drink next and open the bag.

  The opening 31a is the remaining side that is not bonded, and an arbitrary article corresponding to the size of the storage units 31 to 33 can be taken in and out from the opening 31a. In addition, one of the two films is formed so as to protrude from the other film on one side that is not bonded, and the protruding portion serves as a turn 31b. The folding | returning 31b has an adhesion surface, adhere | attaches with a film by closely_contact | adhering to the accommodating parts 31-33, and the opening part 31a closes. By providing such a turn 31b as the break guide portion, the purchaser can easily remove the cap. It should be noted that the replacement cap 40 is not limited to this as long as the replacement cap 40 can be easily taken out from the storage portions 31 to 33 as the break guide portion, and other structures may be used.

  The extension part 34 is an extension of the storage parts 31 to 33, and the storage parts 31 to 33 are independent of each other. However, the extension part 34 is integrated and has a shape of only a side surface portion of a substantially triangular prism. That is, each side surface has a substantially rectangular shape with one side of the boundary with the storage unit 31, a substantially rectangular shape with one side of the boundary with the storage unit 32, and a substantially rectangular shape with one side of the boundary with the storage unit 33. Are bonded to each other at two sides to maintain the shape of the side portion of the substantially triangular prism described above. Further, the upper sides of the side surfaces are bonded to each other halfway, thereby forming a hole 34a having a size smaller than the size of the upper surface of the substantially triangular prism when not bonded.

  Moreover, since the extension part 34 is an extension of the storage parts 31 to 33, it is made of a transparent film as in the case of the storage parts 31 to 33. Along with that, a sheet is sandwiched between the two films. Yes. By sandwiching the sheet, even if an external force about the weight of the replacement cap is applied to the extension portion 34, the extension portion 34 is not distorted, and as a result, the hole 34a is not deformed. This will be specifically described later.

  The extension 34 has a circular hooking hole 34b having a predetermined size at the center of each side surface portion. By passing the hooking hole 34b through a hook or the like, the packaging bag 30 or the packaging bag 20 with a replacement cap can be suspended from the hook or the like. The hooking hole 34b is provided for convenience and is not essential for the implementation of the present invention.

  Next, a packaging bag with a replacement cap in which a replacement cap is placed in the packaging bag 30 described with reference to FIG. 3 will be described with reference to FIG. FIG. 4 is a diagram illustrating a packaging bag with a replacement cap according to the first embodiment. As shown in FIG. 4, the replacement cap 40 is stored in each of the storage portions 31 to 33 of the packaging bag 30, thereby forming the replacement cap-containing packaging bag 20. Specifically, the operator opens the opening 31a of the storage units 31 to 33, inserts the replacement cap 40 from the head, and finally folds the folding 31b to close the opening 31a. Further, in order to keep the freshness of the tea powder, the sealed storage units 31 to 33 are filled with nitrogen gas. Thereby, oxidation of tea powder is prevented and the freshness of tea powder can be maintained. As described above, the replacement cap 40 has a structure in which the tea powder incorporated in the replacement cap 40 falls onto the surface of the drinking water 11 in the PET bottle 10 and is mixed by a predetermined operation of loosening and opening the replacement cap 40 when drinking. .

  Here, the replacement cap 40 will be specifically described with reference to FIGS. 5 and 6. 5 and 6 are cross-sectional views of the replacement cap. As shown in FIG. 5, the replacement cap 40 includes a cap main body 41, a pressing unit operation unit 42, a pressing unit 43, a storage container 44, and tea powder 45. In addition, the cap main body 41, the press part operation part 42, the press part 43, and the storage container 44 consist of synthetic resins, such as a polypropylene resin (PP).

  The cap body 41 has a shape in which the small diameter cylindrical portion 41b is combined with the upper portion of the large diameter cylindrical portion 41a. On the inner peripheral surface of the large-diameter cylindrical portion 41a, there is provided a screw portion 41c that is detachably screwed to the screw portion 10b on the outer periphery of the bottle port 10a of the PET bottle 10. In addition, on the inner peripheral surface of the small-diameter cylindrical portion 41b, a guide projection that fits into a guide groove included in a pressing portion 43 described later is provided in the axial direction.

  The pressing part operation part 42 has a substantially cylindrical shape with a bottom, and the upper part is open, and the lower part is a surface having a protrusion 42a at the center. A threaded portion 42b is provided on the outer peripheral surface of the protrusion 42a. The threaded portion 42b is screwed and coupled to a threaded portion 43a formed on the pressing portion 43 described later. The pressing portion operation unit 42 is attached so as to cover the small-diameter cylindrical portion 41b in the cap main body 41 and is fixed to the small-diameter cylindrical portion 41b so as not to move in the axial direction.

  The pressing portion 43 has a substantially cylindrical shape with a bottom, and one of the upper and lower surfaces is open and the other is closed. The pressing portion 43 is provided with a screw portion 43a that is screwed and coupled to the screw portion 42b formed on the protrusion 42a described above on the inner peripheral surface thereof. Further, the pressing portion 43 has a guide course that fits with the guide protrusion provided on the small-diameter cylindrical portion 41b on the outer peripheral surface thereof. Therefore, the pressing portion 43 moves downward along the guide groove by the rotation of the pressing operation portion 42 and the pressing portion 43 and the screw portion of the pressing operation portion 42 function.

  The storage container 44 includes a side surface portion 44a, a bottom surface portion 44b, a mechanical weak point portion 44c, and a rod portion 44d. The side surface portion 44a has a substantially cylindrical shape, the upper surface is open, and the bottom surface portion 44b is provided on the lower surface. The bottom surface portion 44b forms a storage space together with the side surface portion 44a. The boundary with the side surface portion 44a is a mechanical weak point portion 44c including a thin wall portion and a kerf portion except for a part thereof. The rod portion 44 d is formed integrally with the bottom surface portion 44 b, extends from the bottom surface portion 44 b to the opening on the top surface inside the storage container 44, and contacts the pressing portion 43. Therefore, the bar portion 44 d is pushed downward by the pressing portion 43 when the pressing portion 43 moves downward as the pressing operation portion 42 rotates. As a result, a force is applied to the bottom surface portion 44b, and the mechanical weak point portion 44c is destroyed.

  The inside of the storage container 44 is filled with tea powder 45, falls from the opening formed by breaking the mechanical weak point portion 44c, and mixes with the drinking water 11 in the plastic bottle 10, thereby making the tea it can.

  Specifically, referring to FIG. 6, the mechanical weak point portion 44c, which is the boundary between the side surface portion 44a and the bottom surface portion 44b, is broken by the force applied to the rod portion 44d, and as a result, the opening 46 is formed. Then, the tea powder 45 packed in the storage container 44 falls from the opening 46. In addition, even if the mechanical weak point part 44c is destroyed, the side part 44a and the bottom face part 43b are partially connected. Therefore, a part of the storage container 44 (the bottom part 44b and the bar part 44d) does not fall into the beverage container together with the tea powder 45.

  Although the specific configuration of the replacement cap 40 has been described above, the configuration of the replacement cap 40 is used as a cap that seals the mouth of a beverage container, and a beverage element packed inside by a predetermined operation is a beverage. What is necessary is just to also have a structure which falls to a container, You may comprise any structures other than the present Example 1. FIG.

  Next, how to attach the replacement cap 40 to the plastic bottle 10 will be described with reference to FIG. FIG. 7 is a view for explaining how to attach the replacement cap. As shown in FIG. 7, the operator picks up a part of the extension 34 of the replacement cap-containing packaging bag 20 with his / her thumb and forefinger and picks it up. In the conventional packaging bag, when a plurality of replacement caps are to be attached to the bottle neck 13 of the PET bottle 10, a plurality of caps cannot be picked up at once with only the thumb and forefinger. However, in the packaging bag 20 with the replacement cap according to the first embodiment, since the storage portions 31 to 33 including the plurality of replacement caps 40 are connected by the extension portion 34, if the extension portion 34 is held, the storage portions 31 to 31 are included. 33 can be put together in the hand using only the thumb and index finger.

  Then, the operator holds the replacement cap-containing packaging bag 20 while holding the replacement cap into the replacement cap while aligning the center of the hole 34 a of the replacement cap-containing packaging bag 20 with the center of the cap 12. The packaging bag 20 is lowered. Then, as soon as the head of the cap 12 passes through the extension portion 34, the hand is released from the extension portion 34. Then, the replacement cap-containing packaging bag 20 naturally descends to the bottle neck 13 and the attachment of the replacement cap 40 to the PET bottle 10 is completed.

  Specifically, after the attachment is completed, returning to FIG. 1, the storage bags 31 to 33 are suspended from the bottle neck of the plastic bottle 10 and are arranged radially at intervals of 120 degrees. In this case, it looks good geometrically, and the plastic bottles 1 with replacement caps can be arranged in a predetermined positional relationship. In a conventional packaging bag, if three storage cap-containing storage bags are to be arranged radially at intervals of 120 degrees in this way, first, they must be suspended one by one in order. After suspending all of them, their positions must be adjusted, which is cumbersome. However, since the packaging bag 20 with the replacement cap according to the first embodiment is installed and the storage bags 31 to 33 are arranged as shown in FIG.

  Returning to FIG. 7, the extension portion 34 has a certain degree of rigidity because the sheet is sandwiched between the two films as described above. As shown in FIG. 7, when part of the extension 34 is picked up and lifted, the weight of the three replacement caps is applied to the extension 34 in the packaging bag 20 with the replacement cap. As a result, the hole 34a is not deformed. However, in the first embodiment, the sheet is sandwiched between the two films, but the rigidity generated only by the shape of the extension part 34 (when the transparent part is made of only the same material as the storage parts 31 to 33). If this is sufficient, there is no need to sandwich a sheet between two separate films. In other words, in the case of a packaging bag with a replacement cap that does not have such rigidity in the extension, it may be necessary to work while forming the hole 34b with both hands, which is troublesome. However, the replacement cap-containing packaging bag 20 according to the first embodiment can be operated with one hand, and has an effect that the attaching operation is simplified as compared with the replacement cap-containing packaging bag having no extension in the extension portion.

  By the way, the cap 12 closed from the beginning at the bottle opening 10a of the plastic bottle 10 is the same as the replacement cap 40, and the tea powder built in the cap 12 is a beverage in the plastic bottle 10 by a predetermined operation of loosening and opening the cap when drinking. It consists of a structure that falls onto the water surface and is mixed. The purchaser first makes tea using the cap 12 and, after having finished drinking, takes out the replacement cap 40 from any of the storage units 31 to 33, draws water into the plastic bottle 10, Instead of the cap 12, the replacement cap 40 that has been taken out is attached. The purchaser can similarly make tea using the replacement cap 40.

  In this way, the PET bottle 10 is originally disposable, but by using the replacement cap 40, the PET bottle 10 is reused many times (at least three times), which is effective for environmental measures. be able to. Moreover, the exchange cap 40 is packed with tea powders of different tea production areas for each of the storage units 31 to 33, and can enjoy various types of tea. For example, if the price of a pet bolt 1 with a replacement cap and a packaging bag is 300 yen, 4 cups of tea from various production areas will be 75 yen per cup (currently 120 yen per cup) And can be offered cheaply. It is not always necessary to provide the PET bottle 10 and the replacement cap-containing packaging bag 20 together, and the replacement cap-containing packaging bag 20 may be provided as a single item.

  Next, the packaging bag with a replacement cap according to the second embodiment will be described with reference to FIG. FIG. 8 is a diagram illustrating a packaging bag with a replacement cap according to the second embodiment. In addition, below, only the part corresponding to the extension part 34 of the packaging bag 20 with an exchange cap concerning Example 1 is demonstrated, and description is abbreviate | omitted about the part similar to Example 1. FIG.

  As shown in FIG. 8, the extension portion 54 is an extension of the storage portions 31 to 33, and the storage portions 31 to 33 are independent of each other, but are integrated in a substantially triangular shape, Has a hole 54 a for passing through the neck of the plastic bottle 10. In addition, since the extension portion 54 is an extension of the storage portions 31 to 33, the extension portion 54 is composed of a transparent film as in the case of the storage portions 31 to 33. Along with that, a sheet is sandwiched between the two films. Yes. By sandwiching the sheet, even if an external force about the weight of the replacement cap is applied to the extension portion 54, the extension portion 54 is not distorted, and as a result, the hole portion 54a is not deformed.

  In addition, in the extension part 54 of such a shape, when comprised only with the transparent material of the same material as the accommodating parts 31-33, there exists a possibility that the hole part 54a may deform | transform depending on a material. Therefore, in the packaging bag with a replacement cap according to Example 2, the extension 54 is configured to sandwich the sheet between the two films. However, as described in the first embodiment, when the rigidity generated only by the shape of the extension portion 54 is sufficient, it is not necessary to sandwich the sheet between two separate films.

  Although the first and second embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various other embodiments are within the scope of the technical idea described in the claims. May be implemented.

  In the first embodiment, the replacement cap 40 is filled with tea powder having different production areas for each of the storage units 31 to 33. However, the present invention is not limited to this, and for example, an element of a beverage other than tea is used. It may be coffee, juice, or medicine.

  In the first and second embodiments, the replacement cap 40 is stored in each of the three storage units 31 to 33. However, the present invention is not limited to this, and may have a plurality of storage units. Any configuration may be used. For example, it may have two storage units, each storing a replacement cap.

  Moreover, in Example 1, it was set as the structure of the accommodating part which when the replacement cap 40 was radially arrange | positioned at intervals of 120 degree | times when it attached to the PET bottle 10, This invention is not limited to this. Any configuration may be used as long as it has a plurality of storage portions. For example, the configuration may be such that three storage portions are similarly provided and the three replacement caps 40 are radially arranged at intervals of 60 degrees, 150 degrees, and 150 degrees.

  Moreover, in Example 1, although the accommodating parts 31-33 shall have the opening part 31a and the folding | turning 32b in the lower side, this invention is not limited to this, The bag-like form provided with the fracture | rupture guide part Any one can be used. For example, the entire side of the storage unit may be bonded by heat sealing or the like, and a perforation may be provided at the center.

  Moreover, in Example 1, the accommodating parts 31-33 shall consist of a transparent film, However, This invention is not limited to this, From the film which has light-shielding property for antioxidant of a tea powder. It may be. In that case, since what kind of replacement cap is inside cannot be seen from the outside, the purchaser should be able to select the replacement cap, such as displaying the name of the tea production area in the storage units 31-33. Is desirable.
