Description

The present invention relates to a beverage product in which a beverage is filled in a plastic bottle (hereinafter, referred to as a beverage product in a plastic bottle). More specifically, the present invention relates to a plastic bottled beverage product that can be used in a water server.

In a conventional water server, a large bottle filled with a beverage such as mineral water is loaded, and a built-in cooler or heater heats and cools the beverage supplied from the large bottle, and hot water is discharged from the spout. It is provided to pour cold water. Such large bottles are called gallon bottles and are filled with, for example, 12 liters or, in some cases, 15 liters of beverage, and for the elderly, children and other weak people, replacing the bottle is laborious. There is a problem that it becomes a burden and is accompanied by difficulties.

Therefore, it has been proposed to use a commercially available beverage product containing a plastic bottle (generally called a PET bottle because of the material name) for a water server. In this case, in a commercially available beverage product in a plastic bottle, there is a problem that water leaks when the bottle cap is opened and then the bottle body is turned upside down and attached to the water server. Therefore, when the plastic bottle is attached to the water server, it is necessary to devise a way to prevent the beverage in the bottle from leaking.

For example, a cap with packing has been proposed in which a packing having a cross notch on the surface and a perforated bottle cap having a hole through which a beverage supply nozzle of a bottle insertion port of a water server passes are combined (Patent Document). 1). This cap with packing is sealed with a perforated cap that incorporates the packing inside instead of the bottle cap, so that even if the PET bottle is turned upside down, water will not flow out while sealing the bottle of the water server. When attached to the outlet, it allows the beverage supply nozzle to be inserted into the bottle and allows the water in the PET bottle to be supplied to the water server.

In addition, it is packed in the mouth of a plastic bottle to close the mouth, and when the plastic bottled beverage product is pushed upside down into the bottle insertion port of the water server, it is pushed into the bottle by the beverage supply nozzle to open the mouth. Has been proposed (Patent Document 2). This stopper includes a stopper that is housed in the mouth of a PET bottle and closes the mouth, a ring-shaped regulation part that regulates the movement of the stopper on the back side of the mouth (inside the bottle), and a stopper. It has a columnar connecting part that connects to the regulating part and a covering part that covers the surface of the plug part, and is a ring-shaped regulation that is inserted into the drinking spout first in the process until the plug part is attached to the spout. The gas in the PET bottle that has passed through the part is exhausted to the outside of the PET bottle through the gap between the columnar connecting parts, and when the stopper at the rear end is fitted in the drinking mouth, the drinking mouth is closed and the pet The structure is such that neither air nor beverages flow out of the bottle.

Further, it has been proposed to use a reusable dedicated cap having a valve structure (Patent Document 3). For this cap, the valve body is closed with a spring, the PET bottle is covered, and the PET bottle is attached to the water server to open the valve body with the beverage supply nozzle, and the water in the PET bottle is drained to the water server. It is configured to supply to.

However, in the case of the cap with packing described in Patent Document 1, when the packing and the perforated bottle cap are assembled, or when the PET bottle is covered with the assembled cap with packing, germs and dirt on the packing are found on the packing. There is a risk of sticking. If germs or dirt adhere to the cap with packing, germs or dirt may get mixed into the water of the water server, causing hygiene problems.

Further, also in the stopper of Patent Document 2, when the stopper is pushed into the drinking spout after opening the bottle cap, the stopper is pushed through the covering portion at the top of the stopper, and after the pushing, the covering portion is removed so that various germs are contained in the bottle. However, it is unavoidable that germs and the like may be mixed into the beverage by touching the stopper portion pushed into the bottle. Moreover, since the number of parts constituting the stopper is large and the structure is complicated, there is a problem that the cost is high.

Further, even with the special cap of Patent Document 3, when the special cap is attached after opening the bottle cap, it cannot be excluded that various germs may adhere to the server and be mixed in the server. Moreover, there is a problem that the configuration of the dedicated cap is complicated and expensive, such as using a spring.

Further, any cap or stopper has a problem that it takes time and effort to install it in place of the bottle cap and cannot be easily set on the water server and used.

The present invention is for a water server that allows the plastic bottle to be attached to the server without touching the drinking spout with the minimum simple work of turning the plastic bottle with the bottle cap upside down and inserting it into the bottle slot of the server. The purpose is to provide beverage products in plastic bottles.

In order to achieve such an object, the plastic bottled beverage product for a water server according to claim 1 closes a bottle body filled with a beverage, a bottle cap covering the drinking port of the bottle body, and an opening of the drinking port. It is provided with at least an impermeable sealing member.

Here, it is preferable that the sealing member is adhered to at least the mouth edge of the drinking spout in a loosened state or a stretched state.

Further, the sealing member is preferably a porous film that allows gas to pass through without allowing moisture to permeate.

Further, it is preferable that the seal member is provided with a fragile portion that is torn when the beverage supply nozzle at the bottle insertion port of the water server is pushed in.

According to the beverage product in a plastic bottle of the present invention, the plastic bottle can be attached to the server without touching the drinking spout at all, so that the risk of contamination with germs can be suppressed and hygienic safety can be ensured.

Moreover, according to the beverage product in a plastic bottle of the present invention, the server can be turned upside down by simply opening the bottle cap of the plastic bottle without the need to attach any other parts (such as a special cap). You can attach a plastic bottle to the server with the minimum of simple work of inserting it into the bottle slot.

Hereinafter, the configuration of the present invention will be described in detail based on the embodiments shown in the drawings.

1 to 3 show an embodiment of a beverage product in a plastic bottle for a water server according to the present invention. The beverage product 1 in a plastic bottle of this embodiment includes a bottle body 2 filled with a beverage 5, a bottle cap 3 that closes a drinking port 6 of the bottle body 2, and a sealing member 4 that seals the drinking port 6 and at least does not allow moisture to permeate. It is suitable for a water server with a weight and size that allows the bottle to be easily replaced by a weak person such as an elderly person or a child.

Plastic bottles commonly used as beverage containers are widely used in which a bottle body 2 mainly made of polyethylene terephthalate (PET) is filled with a beverage and sealed with a bottle cap 3 mainly made of polypropylene, polyethylene or the like. are doing. Since the bottle body 2 uses polyethylene terephthalate (PET) as the main material, it is generally called a PET bottle.

Examples of the plastic bottle include a sterile filling PET bottle for accommodating water, tea and the like, a pressure-resistant PET bottle for accommodating carbonated drinks, and a heat-resistant PET bottle for accommodating fruit juice beverages, hot drinks and the like.

In the bottle body 2, for example, a tubular body portion 16 whose lower end is closed by blow molding or the like, a shoulder portion 17 formed thinner than the body portion 16, and a cylindrical drinking spout 6 are continuously integrally molded. Has been done. In the present embodiment, the body portion 16 is formed in a square tubular shape and the drinking spout 6 is formed in a cylindrical shape, but the shape of the body portion 16 is arbitrary.

On the outer periphery of the spout 6, a male screw portion 7 that can be screwed with the bottle cap 3, an upper flange portion 8 formed below the male screw portion 7, and a lower flange portion 9 formed below the upper flange portion 8 are formed. And are formed. In the present embodiment, the male threaded portion 7 is continuously formed in a spiral shape, but a part thereof may be divided. Further, in the present embodiment, the upper flange portion 8 and the lower flange portion 9 are each continuously formed, but a part thereof may be divided. The lower flange portion 9 is formed to have a larger diameter than the upper flange portion 8.

As shown in FIG. 1, for example, the bottle cap 3 has a cap main body 11, an end ring 12 provided on the lower side of the cap main body 11, and a fragile portion 13 formed at the boundary between the cap main body 11 and the end ring 12. Have. That is, the cap body 11 and the end ring 12 are integrally molded via the fragile portion 13. Further, in the cap body 11, a female screw portion 14 to be screwed with the male screw portion 7 of the drinking port 6 of the bottle body 2 is formed on the inner peripheral surface of the cylinder, and the drinking port 6 of the bottle body 2 is formed inside the upper end surface. It has a ring-shaped inner lip 15 to be inserted inside, and the bottle body 2 is sealed by pressing the inner lip 15 into the inner peripheral surface side near the mouth edge 10 of the drinking spout 6 of the bottle body 2. (See Fig. 2).

As shown in FIG. 4, the bottle cap 3 is not provided with the inner lip 15, and is provided with an elastic packing 19 made of PE foamed PP sheet, PE foamed PE sheet, butyl rubber, or the like on the ceiling of the internal space. By accommodating the bottle in the surface portion, a seal structure may be formed between the bottle body 2 and the portion of the mouth edge 10 (for example, Japanese Patent Application Laid-Open No. 2015-227179). In the case of the bottle cap 3, the sealing member 4 does not receive a concentrated load except that it is sandwiched between the bottle cap 3 and the bottle body 2 at the portion of the mouth edge 10 of the drinking spout 6.

When the bottle cap 3 is turned in the opening direction from the state where the bottle cap 3 is fixed to the bottle body 2, the cap body 11 rises, while the rise of the end ring 12 is blocked by the upper flange portion 8. As a result, each connecting portion of the fragile portion 13 is cut while being stretched, and the cap body 11 is detached from the bottle body 2 with the end ring 12 remaining on the side of the bottle body 2.

Although the size of the plastic bottle is generally the same for the mouthpiece 6 (in other words, the size of the bottle cap 3 is the same), the volume of the bottle body 2 is not particularly standardized, so it is roughly the same. The current situation is that the actual volume is determined as a result of giving priority to the design, etc., even though the size is planned. On the other hand, the capacity of the plastic bottle is not limited to a specific capacity, and it is preferable that the capacity of the plastic bottle can be appropriately selected in consideration of the troublesomeness of replacement frequency and the burden of weight at the time of replacement. Therefore, as the volume of the bottle body 2, for example, 1000 ml and 2000 ml, which are generally used as beverage products in PET bottles having a relatively large capacity, are convenient for handling in the process, but are not particularly limited, for example. Relatively uncommon volumes such as 800 ml, 1500 ml and 2500 ml may be used, and in some cases larger volumes or relatively larger volumes such as 120 ml, 300 ml, 350 ml, 500 ml and 600 ml. It may be a small capacity one.

The sealing member 4 may be at least a film that does not allow moisture to permeate, and is not limited to a specific material. For example, a polypropylene (PP) film, a polyethylene (PE) film, or polyethylene or polyethylene and another film can be used. It is preferable to use a film that can be easily heat-sealed, such as a film in which polyethylene is laminated. Further, as the sealing member 4, it is preferable to use a film that allows gas to pass through without allowing the film moisture to permeate, for example, a porous film having micropores. As the porous film, for example, a porous film made of a fluororesin having fine pores (fluororesin porous film), for example, a PTFE film manufactured by Nitto Denko Co., Ltd .: trade name TEMISH (registered trademark) is used. preferable.

The adhesive portion to the sealing member 4 and the bottle cap 3 has sufficient strength so that the bottle body 2 will not be torn or peeled off due to the weight or impact of the beverage of the contents when the bottle body 2 is turned upside down or shaken. It is desired that the strength of the beverage supply nozzle 22 to be broken by the concentrated load applied by the nozzle 22 when pressed against the beverage supply nozzle 22 is compatible.

Further, as shown in FIG. 4, the seal member 4 has a fragile portion 18 that is torn by the beverage supply nozzle 22 of the bottle insertion port 21 of the water server 20 being pushed in, for example, a shallow cut such as a cross or a rhombus. A thin portion such as a notch or a circle may be provided. The fragile portions 18 such as these notches and thin-walled portions can be accurately formed by controlled processing in a factory. In addition, the bottle cap 3 isolates the bottle from the outside air not only when the seal member 4 is processed under manufacturing control and when the bottle is attached to the mouth edge 10 of the drinking spout 6 but also after the bottle is tapped. , Sanitation under factory control is maintained.

In the case of the bottle cap 3 provided with the inner lip 15 as shown in FIG. 1, the sealing member 4 is preferably adhered to the mouth edge 10 of the drinking spout 6 of the bottle body 2 with a slack. For example, the film 4 is welded to the mouth edge 10 with a bottle sealer or the like while being slightly pushed in while being addressed to the mouth edge 10. Therefore, even when the bottle cap 3 is plugged, the sealing member 4 is not pierced by the annular inner lip (inner annular edge portion) 15 inside the bottle cap 3. Further, even if the internal pressure increases during transportation, in the distribution process, or when the bottle body 2 is gripped, the air or gas accumulated in the upper part of the bottle body 2 permeates the seal member 4 to the bottle cap side. Since the internal pressure is adjusted by moving, the seal member 4 is not damaged.

Further, as shown in FIG. 4, in the case of the bottle cap 3 which is provided with the elastic packing 19 instead of the inner lip 15 to form the seal structure, the seal member 4 has a mouth edge in a tense state without slack. It may be sealed / sealed by adhering it to 10 with a heat seal or the like.

Here, as the beverage filled in the plastic bottle, for example, not only water such as mineral water and RO (reverse permeation) water and tea, but also various beverages such as coffee and black tea, fruit juice beverage and the like can be used. .. Further, when the sealing member 4 is a gas permeable film, it is possible to fill a carbonated drink. When a plastic bottle is subjected to some kind of impact or temperature change, even if the dissolved carbon dioxide gas is generated as bubbles and the internal gas pressure of the bottle body 2 changes, it permeates through the seal member 4. By eliminating the pressure difference between the inside and outside of the seal member 4, the seal member 4 is not broken.

Although not shown in detail, the water server 20 has a bottle insertion port 21 provided with a beverage supply nozzle 22 on the upper surface 23 of the housing, and the bottle insertion port 21 has a plastic bottle drinking port 6 and a shoulder portion. By charging 17, the plastic bottle is supported by the server, and the beverage supply nozzle 22 is arranged in the bottle body 2. The beverage supply nozzle 22 has a water supply hole 24, and is configured to be able to supply the beverage 5 in the bottle from the water supply hole 24 by penetrating the sealing member 4 made of a film and inserting it into the bottle body 2. ing.

As a general structure of the bottle insertion port 21, a structure in which a beverage supply nozzle 22 having a water supply hole 24 is provided on the upper surface 23 of the water server 20 can be exemplified. In such a water server 20, the beverage supply nozzle 22 is inserted into the inside from the drinking port 6 of the bottle body 2, so that the beverage 5 in the bottle flows into the water supply hole 24 by its own weight and is supplied to the water server 20. It is configured as follows. For example, in a water server, the shape around the beverage supply nozzle is formed so that the outer shape of the PET bottle fits, thereby supporting the PET bottle in the opposite direction.

In the plastic bottle configured as described above, as shown in FIGS. 1 and 2, the bottle body 2 and the bottle cap 3 are separately molded, and the sealing member 4 is placed in a state where the bottle body 2 is filled with a beverage. The bottle cap 3 is sealed by being adhered to the mouth edge 10 of the drinking port 6 and press-fitting the bottle cap 3 into the drinking port 6 of the bottle body 2. This work is called "plugging", and the end ring 12 of the bottle cap 3 gets over the upper flange portion 8 of the drinking port 6 at the time of tapping.

At this time, since the seal member 4 is adhered to the mouth edge 10 of the drinking port 6 of the bottle body 2 with a slack, the annular inner lip 15 inside the bottle cap 3 is pushed into the inside of the drinking port 6. Even if this happens, the seal member 4 will not be torn by loosening toward the inside of the bottle body 2. Further, even if the internal pressure increases during transportation, in the distribution process, or when the bottle body 2 is grasped, the air or gas accumulated in the upper part of the bottle permeates the sealing member 4 and moves to the bottle cap 3 side. Since the internal pressure is adjusted in, the seal member 4 is not damaged. Of course, even if the seal member 4 does not have gas permeability, it has slack, so that a certain pressure change is absorbed by the deformation of the seal member 4 itself.

Further, in the case of the bottle cap 3 as shown in FIG. 4, the film-shaped sealing member 4 is adhered by a heat seal or the like in a state where the film-shaped sealing member 4 is tightly stretched on the mouth edge 10 of the drinking spout 6 of the bottle body 2. And the surplus is removed as needed. For example, the sealing plate (iron) is heated, and the film-shaped sealing member 4 is thermocompression-bonded by pressing it onto the sealing target portion, that is, at least the mouth edge 10 of the drinking spout 6. In this case, the sealing plate (iron) can be thermocompression-bonded by pressing the sealing plate (iron) against the sealing target portion so that the mouth edge 10 of the drinking spout 6 of the bottle body 2 is uniformly pressured as a whole, so that the film can be applied to the sealing portion. Wrinkles are less likely to occur, and even if the seal width is narrow, the occurrence of seal defects is reduced.

Of course, the adhesive portion of the seal member 4 to the bottle cap 3 is not limited to the portion of the mouth edge 10 described above, and may be spread over a wide range over the inner peripheral surface side or the outer peripheral surface side of the mouth edge 10. For example, as shown in FIG. 1, when the sealing member 4 is adhered / welded by loosening it so as to be recessed inside the drinking spout 6, it may be adhered to the inner peripheral surface side of the drinking spout 6 or in some cases. Although not shown, the adhesive region may be expanded so as to cover the threaded portion on the outer peripheral surface side of the drinking spout 6. Above all, in the case of the bottle structure shown in FIG. 4, in which the sealing member 4 is heat-sealed on the mouth edge 10 of the drinking spout 6 without slack, the adhesive region covers the threaded portion 7 on the outer peripheral surface. It is effective to expand.

Next, mounting of the beverage product 1 in a PET bottle for a water server will be described with reference to FIG.
First, the bottle cap 3 of the beverage product 1 in a PET bottle is opened. At this time, the bottle cap of the plastic bottle can be opened for the first time. That is, the seal member 4 that covers the drinking spout 6 of the bottle body 2 is exposed for the first time and is exposed to the outside air. Therefore, the quality of the PET bottled beverage product 1 in the manufacturing process and the quality of hygiene are maintained through the distribution process until it is attached to the water server 20.

Therefore, the bottle body 2 is turned upside down and charged into the bottle insertion port 21 while facing the water supply nozzle 22 of the bottle insertion port 21 of the water server 20 so as to address the seal member 4 that closes the drinking port 6. do. At this time, since the drinking port 6 of the bottle body 2 is closed by the sealing member 4 that does not allow water to permeate, the beverage 5 in the bottle does not leak even if the bottle body 2 is turned upside down.

Then, by pushing down the bottle body 2, the beverage supply nozzle 22 of the bottle insertion port 21 of the water server 20 is relatively inserted toward the inside of the drinking port 6, so that the sealing member 4 is broken and the beverage is consumed. The supply nozzle 22 is arranged inside the bottle body 2. As a result, the beverage 5 in the bottle is supplied to the water server 20 from the beverage supply nozzle 22.

According to the present embodiment, the user simply opens the bottle cap 3 of the plastic bottle and does not need to attach any other parts (such as a special cap), and the bottle body 2 is turned upside down to make the bottle of the server 20. It requires only a minimum of simple work by inserting it into the insertion port 21. Moreover, since it can be set on the server 20 without touching the drinking port 6 of the bottle body 2 and the sealing member 4 for preventing the outflow of the beverage 5, germs do not adhere to it. As a result, it is possible to prevent the adhesion and contamination of various germs in the server 20 and in the bottle insertion port 21, and it is possible to ensure the hygienic safety of the water server.

The above-mentioned embodiment is an example of a preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, in the above-described embodiment, at least a film that does not allow moisture to permeate as the sealing member 4 is loosened or stretched without being loosened and adhered to the drinking spout 6 of the bottle body 2. However, in some cases, a sealing member (not shown) molded into an inner cap shape with a flange that fits into the drinking spout 6 may be used. In the case of the inner cap-shaped seal member, the seal member is fitted into the drinking spout 6, and the flange portion is welded to the mouth edge 10 of the drinking spout 6, whereby the inner peripheral surface of the drinking spout 6 is further welded. The drinking spout 6 can be sealed by adhering the portion in contact with the mouthpiece 6. Also, a sealing member of strength and size that allows the entire flanged inner cap, or in some cases only a portion of the bottom of the resin molded cap, to be pierced by the beverage supply nozzle 22 of the server 20, for example a film that is at least impermeable to moisture. Alternatively, it may be formed of a porous film having micropores that allow gas to pass through without allowing moisture to permeate.
