Description

  The present invention relates to a container for refilling and repeatedly using toiletries such as liquid detergents and softeners and foods such as edible oil and instant coffee, and relates to a one-touch repeated use container that can be easily refilled.

Toiletries such as liquid detergents and shampoos, and foods such as edible oils, seasonings, and instant coffee are each stored in dedicated containers that are easy to use.
The dedicated container has a solid structure and is therefore expensive, so a product with a refill container that refills only the contents is sold separately so that it can be used repeatedly when the contents are gone. There are many.

  For example, liquid detergent containers need to be weighed and taken out each time they are used, so a rigid plastic container with a nozzle at the spout is repeatedly used to make it easier to pour into a measuring cup. Used as a container. In contrast to this container, as a refilling container for replenishing the contents, a flexible container made of a flexible packaging film, a container in which a spout is formed, or a container attached with a stopper is generally used. ing.

Since the rigid container to be used repeatedly is designed to be easily poured out, considering the convenience in the refilling operation of replenishing the contents from the refilling container to the container to be used repeatedly, Not necessarily.
On the other hand, the refill container is not always in consideration of the convenience in the refilling operation, because the emphasis is on manufacturing inexpensively.

  With respect to this problem, in Patent Document 1, it is possible to open a refill container by using a nozzle provided in a container that is repeatedly used, and further hold it by hand during refilling so that the refill container is self-supporting. Refillable containers have been proposed that do not need to be.

The refill container includes a fixing member that is fixed to the refill container main body, a coupling member that is screwed to the opening of the reusable container, and a container sealing member that is disposed between the fixing member and the coupling member. In this case, the refill container is inverted and the connecting member is repeatedly screwed to the opening of the container for use.
However, since the refill container described in Patent Document 1 is screwed and connected to the opening of the reusable container, it is necessary to turn the screw during the refilling operation, which is not always convenient for the consumer. There wasn't.

Furthermore, since this refill container uses two members, a coupling member and a container sealing member, in order to couple the reusable container and the refill container, the cost of the container must be high. There was a disadvantage that it could not be obtained.
In addition, since the refill container is used by screwing it into the opening of the container to be used repeatedly, the connection between the two is reliable, but on the other hand, it is not only cumbersome to operate but also disadvantageous in terms of the cost of the plug. The fault of being was also left behind.

  In Patent Document 2, even when the content liquid is refilled from a flexible pouch container, the contents in the mouth of the bottle container (repetitively used container) can be easily and reliably regardless of the orientation of the pouch container (refill container). A container connector assembly, a pouch container spout member, and a bottle container main body cap that can inject liquid and are easy to handle have been proposed.

  This container connector assembly is a container connector assembly comprising a spout member that is liquid-tightly joined to a pouch container and a body cap that is liquid-tightly fitted to the mouth of the bottle container and guides the dispensing of the content liquid. The spout member has a spout tube for pouring and guiding content liquid, a liquid passage formed in a center line direction of the spout tube, and a thin film closing the passage, and the body cap Has a spike needle portion at the liquid dispensing portion and a liquid guide tube outside the spike needle portion, and the spike needle portion can pierce the through-hole communicating with the inside and outside of the main body cap and the thin film. It has a sharp tip, and the spout member and the main body cap can be connected in a state where the spike needle portion is located inside the spout tube and the liquid guide tube is located outside the spout tube. It is a container connector assembly

  Further, the main body cap is a main body cap that is liquid-tightly fitted to the mouth portion of the bottle container and guides the dispensing of the content liquid, and the spike needle portion and the spike needle portion are disposed in the content liquid dispensing portion. A liquid guide tube is provided on the outer side, the spike needle portion has a through hole communicating with the inside and outside of the main body cap and a sharp tip, and the liquid guide tube has a communication hole communicating with the inside and outside of the main body cap. It is a main body cap for bottle containers.

  The spike needle (opening part) of this bottle container main body cap was raised from the bottom surface of the nozzle cap, that is, it was placed at the same height as the bottom surface of the nozzle cap that became the inner and outer boundaries of the main body cap. Since the area of the communication hole that can be provided as a part is small and the cross-sectional area inside the nozzle cap is also narrow, it was frequently found that clogging occurred during repeated use.

  In Patent Document 3, a repetitive container is generally provided with a pour nozzle and an overcap covering this pour nozzle, and a pour as a repetitive container that can be replenished with simple operations. The nozzle includes an opening portion having a tip for breaking and opening the sealing member of the refill container for replenishing the contents, and the overcap includes a cylindrical side wall and a ceiling detachably configured on the side wall. Repeated use containers composed of plates have been proposed.

  According to this reusable container, when replenishing the contents, first remove the top plate to expose the nozzle cap, then invert the refill container, let the tip of the nozzle pass through the sealing member of the refill container, The refill container is opened by breaking the sealing member.

  Thus, since the refill container is opened only after contacting the tip of the nozzle, there is no need to open the refill container in advance, and there is no risk of accidentally spilling around. And most of the contents that flowed out by opening are repeatedly filled into the use container through the inside of the pouring nozzle, but the contents that partially flowed out of the pouring nozzle are also surrounded by the cylindrical side wall. Since the inside of the container for repeated use is surely filled through, there is no spillage at this time.

  However, since the dispensing nozzle of the repeated use container is arranged at the same height as the bottom surface of the nozzle cap, the lower part of which is the same as the repeated use container proposed in Patent Document 2, Since the area of the communication hole that can be provided as the opening region is small, there is a risk of clogging during repeated use.

JP 2004-99082 A Japanese Patent Laid-Open No. 9-193554 JP 2011-20742 A

  In view of the above circumstances, the present invention enables easy and reliable injection of the content liquid from the refill container to the repeated use container when refilling the content liquid from the refill container to the repeated use container, and is easy to handle. It is an object to provide a container for repeated use.

That is, the invention according to claim 1 of the present invention includes a container main body, a nozzle cap that is attached to the opening of the container main body and has a nozzle for pouring, and an overcap that covers the nozzle cap. In the repetitively used container for replenishing the contents through the nozzle cap, the nozzle cap is provided with a dispensing nozzle having a slit for air replacement at the time of refilling standing at the center thereof, and refilling the contents An opening portion for breaking and opening the sealing member of the container is disposed in the dispensing nozzle, the opening portion is disposed above the bottom surface of the nozzle cap , and the opening portion on the side of the note exit nozzle slits at the lower end, repeated use containers der characterized in that the opposite side of the slit is provided with baffle plates so as to open .

  A container for repeated use, comprising a container body, a nozzle cap attached to the opening of the container body and having a dispensing nozzle, and an overcap covering the nozzle cap, and replenishing the contents through the nozzle cap The nozzle cap is provided with a dispensing nozzle that has a slit for air replacement at the time of refilling, and is opened at the center of the nozzle cap to break and open the sealing member of the refill container that replenishes the contents. Is disposed in the dispensing nozzle so that the top plate is removed to expose the nozzle cap, and then the refill container is turned upside down to seal the refill container. The refill container can be opened by allowing the tip of the nozzle to pass through and breaking the sealing member.

Thus, since the refill container is opened only after contacting the tip of the nozzle, there is no need to open the refill container in advance, and there is no risk of accidentally spilling around.
And most of the contents that flowed out by opening are repeatedly filled into the use container through the inside of the pouring nozzle, but the contents that partially flowed out of the pouring nozzle are also surrounded by the cylindrical side wall. Since the inside of the container for repeated use is surely filled through, there is no spillage at this time.

Further, since the opening portion is disposed above the bottom surface of the nozzle cap, the bottom surface portion of the nozzle for dispensing does not close the opening portion of the bottom surface of the nozzle cap, and the opening portion can be opened even during repeated use. There is no longer any clogging.
The larger the inner diameter of the nozzle cap, the shorter the time required for refilling, but it is desirable that the inner diameter is 20 mm or less in consideration of workability during measurement.
In addition, by providing the baffle plate, it is possible to prevent excessive dispensing by adjusting the dispensing flow rate when the contents are repeatedly dispensed from the container for use (during measurement).
Further, by providing a baffle plate on the side of the slit of the nozzle cap that opens the opposite side of the slit, the replacement flow path for air in the repeated use container when refilling the contents from the refill container to the repeated use container Can be secured and the refilling speed can be increased.

The invention according to claim 2 of the present invention is the repeated use container according to claim 1, wherein the opening portion has a cylindrical shape.
Since the opening part has a cylindrical shape, the contents move in a rectified state through the cavity inside the cylinder when refilling, so it is less likely to block the air gap of the nozzle for air replacement, and the contents can be shortened in a short time. Can be refilled.

The invention according to claim 3 of the present invention is the container for repeated use according to claim 1, wherein the opening portion has a plate shape.
Since the opening part has a plate shape, it is possible to select a sharp shape at the tip with a shape that does not obstruct the movement of the contents through the cavity inside the nozzle when refilling, and the content can be selected in a short time You can refill things.

The invention according to claim 4 of the present invention is characterized in that a length for breaking and inserting the sealing member of the refill container from the tip of the opening portion is equal to or greater than the inner diameter of the cap of the refill container. It is a repeated use container of any one of 1-3.
In the state where the sealing member piece when the tip of the opening portion breaks the sealing member of the refill container remains connected to the sealing portion outside the tip of the opening portion, this member piece passes through the flow path of the contents. It happens to be blocked.
Flow with the broken sealing member by setting the length of the sealing member of the refill container to be broken and inserted from the front end of the opening portion to be equal to or larger than the inner diameter of the plug of the refill container to which the sealing member is adhered. Since the road can be prevented from being blocked, the refilling operation can be performed smoothly.

  As described above, according to the repeated use container of the present invention, when refilling the content liquid from the refill container into the repeated use container, the content liquid can be easily and quickly injected from the refill container into the used container. In addition, since it is not necessary to operate a screw or the like, it is possible to provide a reusable container that can be replenished very easily, has little clogging of contents, and is easy to handle.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an upper cross-sectional schematic view of an example of the reusable container of the present invention, FIG. 2 is a cross-sectional schematic view of the reusable container (FIG. 1) of the present invention (FIG. 1), and FIG. FIG. 4 shows a schematic top view of the bottom portion of FIG. 1) when viewed from above, and FIG.

For comparison, FIGS. 5 to 8 are explanatory views of an example of a conventional repeated use container corresponding to FIGS. 1 to 4 described above. That is, FIG. 5 is a schematic top cross-sectional view of a conventional reusable container, FIG. 6 is a schematic cross-sectional view of a conventional reusable container (FIG. 5) taken along the line aa ′, and FIG. FIG. 8 shows a schematic view seen from above, and FIG. 8 shows a schematic cross-sectional view of the upper part when the conventional container for repeated use is opened.

First, an example of an embodiment of a conventional repeated use container will be described.
The main body (11) of the repeated use container (1) is, for example, a plastic blow bottle, and a nozzle cap (12) is attached to the opening. The nozzle cap (12) has a pouring nozzle (121) upright at the center thereof. As can be seen from FIGS. 5 and 6, the pouring nozzle (121) has a substantially cylindrical shape in cross section, and the notch (12 a) is formed at a position corresponding to the bottom of the cylindrical tube. Have. The inside of this cylindrical shape is a cavity communicating with the inside of the repeated use container (1).

And the opening part (124) provided inside the pouring nozzle (121) has the shape by which the upper front-end | tip was cut off diagonally, and the front-end | tip is the sealing member (23) of the refill container mentioned later. It has a sharp shape so that it can be broken. And when using, by tilting the container (1) repeatedly, the contents are guided to the substantially cylindrical pouring nozzle (121) and poured out to the outside.
In addition, a slit (12b) is provided continuously to the notch (12a), and air is repeatedly introduced into the use container (1) through the slit (12b) at the time of pouring.

In the nozzle cap (12), the content returning flow path (122) surrounds the periphery of the pouring nozzle (121) erected at the center, and the peripheral wall (123) surrounds the periphery. . In this way, the content returning flow path (122) sandwiched between the pouring nozzle (121) and the peripheral wall (123) communicates with the slit (12b) on the downstream side.
After the contents are poured out from the dispensing nozzle (121), the contents adhering to the tip of the dispensing nozzle (121) are dropped into the contents return channel (122) and pass through the slit (12b). Return to the inside of the container (1) for repeated use.

For this reason, the content adhering to the tip of the pouring nozzle (121) is not repeatedly spilled outside the use container (1), and the surroundings are not soiled.
In addition, the height of the peripheral wall (123) is lower than that of the pouring nozzle (121) so that the peripheral wall (123) does not interfere with the pouring operation when the container (1) is repeatedly tilted to pour the contents. ing.

In addition, the repeated use container (1) shown in FIG. 5 is provided with the overcap (not shown) which covers a nozzle cap (12) via packing. This is to prevent impurities from being mixed into the inside of the container (1) repeatedly during storage.
The overcap may also have a function of preventing the contents from spilling when the container falls.
In general, the overcap usually serves as a measuring cup that measures the amount of the overcap by pouring the contents from the repeated use container (1) into the overcap.

The inner diameter of the dispensing nozzle (121) is slightly larger than the outer diameter of the plug (22) of the refill container.
For this reason, the pouring nozzle (121) can serve as a cylindrical guide member for guiding the plug (22) when the container (1) is replenished with the contents (see FIG. 8). .

In FIG. 8, the schematic of the upper cross section at the time of opening the refill container of a repeated use container (1) was shown. The refill container body is omitted from the figure.
At the time of opening, the sealing member (23) such as a film or aluminum foil attached to the outlet (22) outlet of the refill container is broken at the tip of the pouring nozzle (121). At this time, most of the content flows out into the pouring nozzle (121), but may partially flow out of the pouring nozzle (121).

  In addition, the contents may scatter around when the sealing member (23) is broken. In order to solve this problem, when the sealing member (23) is broken by configuring the height of the cylindrical side wall of the overcap higher than the tip of the pouring nozzle, the tip of the plug (22) is the side wall. Therefore, the contents flowing out from the refill container flow out into the side wall, and the entire amount can be repeatedly guided into the use container (1) without splashing.

6 is a schematic cross-sectional view taken along the line aa ′ of the bottle of FIG. 5, and FIG. 7 is a schematic view of the bottom of the bottle of FIG.
In this bottle, the cylindrical opening portion (124) with a sharp tip is held in connection with the bottom surface C of the nozzle cap (12), so that the bottom surface of the dispensing nozzle as shown in FIG. As a result, the opening area on the bottom surface of the nozzle cap closed and narrowed, and as a result, the opening area was often clogged when repeatedly used (see FIG. 7).

  Moreover, in this bottle, since the cylindrical opening part (124) exists from the bottom face (C) of the nozzle cap (12) to the inside of the pouring nozzle (121) near its tip, it is shown in FIG. Thus, the cross-sectional area inside the dispensing nozzle (121) becomes narrow, and as a result, not only clogging occurs when repeated use is repeated, but refilling often takes time (Fig. 6).

  In contrast, an example of a repeated use container according to an embodiment of the present invention will be described below with reference to FIGS.

The main body (11) of the repeated use container (1) according to the present invention is, for example, a plastic blow bottle, and a nozzle cap (12) is attached to the opening thereof. The nozzle cap (12) has a pouring nozzle (121) upright at the center thereof.
As can be seen from FIG. 1, the dispensing nozzle (121) has a substantially cylindrical cross section, and has a notch (12a) at a position corresponding to the bottom of the cylindrical shape. The inside of this cylindrical shape is a cavity communicating with the inside of the repeated use container (1).

And in the pouring nozzle (121), the opening part which breaks and opens the sealing member of the refill container which replenishes contents is arranged above the bottom face C of the nozzle cap (12), The tip has a sharp shape so that the sealing member (23) of the refill container can be broken.
Normally, the nozzle cap (12) is made of a plastic such as polyethylene resin that is integrally molded with a dispensing nozzle (121) having an opening (124) inside thereof by a method such as injection molding. Since the tip oblique portion of the opening portion (124) is covered with the dispensing nozzle (121), there is no fear of directly touching the body such as a hand or eyes.

2 is a schematic cross-sectional view taken along the line aa ′ of the bottle of FIG. 1, and FIG. 3 is a schematic view of the bottom of the bottle of FIG.
In this bottle, since the cylindrical opening part (124) with a sharp tip is held by the opening part holding tool (125) inside the pouring nozzle, as shown in FIG. 3, the pouring nozzle The bottom surface portion of the nozzle cap does not close and narrow the opening region of the bottom surface of the nozzle cap. As a result, even when repeated use is repeated, the opening region is less clogged.

  Moreover, in this bottle, since the cylindrical opening part (124) is fixed inside the dispensing nozzle (121) at a position higher than the bottom surface C of the nozzle cap (12), as shown in FIG. There are few portions where the cross-sectional area inside the dispensing nozzle (121) becomes narrow, and as a result, clogging does not occur when repeated use is repeated, and the time required for refilling can be shortened.

In the above embodiment, the case where the container for repeated use according to the present invention is a cylindrical shape in which the shape of the opening portion (124) is cut obliquely at the tip is described.
Since the opening part (124) has a cylindrical shape, the contents move in a rectified state through the cavity inside the cylinder at the time of refilling, so that the contents can be refilled in a short time.

The shape of the opening portion (124) is not limited to a cylindrical shape, and may be, for example, a plate shape. Since the opening portion has a plate-like shape, it is possible to select a sharp shape with a shape that is less likely to obstruct the flow path in which the contents move through the cavity inside the nozzle during refilling.
9 (1) shows a case where the shape of the opening (124) is a cylindrical shape, and FIG. 9 (2) shows a case where the shape of the opening (124) is a plate. The appearance of was illustrated.

  In the upper cross-sectional schematic diagram at the time of opening shown in FIG. 4, the length B for breaking and inserting the sealing member (23) of the refill container from the tip of the opening (124) is the inner diameter of the plug (22) of the refill container. By being A or more, the contents can be smoothly refilled without causing a flow path obstruction due to a fragment of the sealing member (23).

In a state where the sealing member piece when the tip of the opening portion (124) breaks the sealing member (23) of the refill container remains connected to the sealing portion in the flow channel just outside the opening portion tip. This happens that the piece of material blocks the flow of the contents.
The length (B in FIG. 4) for breaking and inserting the sealing member of the refill container from the front end of the opening portion (124) is set to the plug (22) of the refill container to which the sealing member (23) is adhered. It is possible to prevent the flow path from being blocked as described above by the broken sealing member by setting the inner diameter (A in FIG. 4) or more.

  Furthermore, in the repetitive container of the present invention, as shown in FIG. 10, there is an obstruction that the opposite side of the slit opens on the slit (12b) side of the dispensing nozzle (121) at the lower end of the opening portion (124). A plate can also be provided. By providing the baffle plate (127) at the lower end of the unsealing part (124), it is possible to prevent excessive discharge by suppressing the flow rate when the contents are repeatedly discharged from the container (usage). .

  In addition, by providing a baffle plate (127) that opens the opposite side of the slit on the slit (12b) side of the nozzle cap (12), the content flow D and the air flow E at the time of refilling are separated. Thus, when the contents are refilled from the refill container to the reusable container, the refill speed can be increased by securing a replacement flow path for the air in the reusable container.

As the refill container used for refilling the contents of the repetitive container of the present invention, a soft plastic pouch or a plastic blow bottle having a mouth and neck portion is usually used.
As a material of the pouch or bottle, a known plastic such as polyethylene terephthalate resin, polyethylene resin, or polypropylene resin is used.

And the mouth-and-neck part is used as the refill container stopper (22), and the sealing member (23) is adhered and closed to the opening. Furthermore, the cap which covers a sealing member (23) via packing is provided.
The contents are preferably liquid, and examples include toiletries such as liquid detergents and softeners, edible oils, and instant coffee.

Although it does not specifically limit as a sealing member (23) of a refilling container, The thing which is scarcely extensible and is easy to fracture | rupture is preferable. For example, it is a plastic film with poor extensibility.
Or the laminated body etc. which bonded aluminum foil, paper, a cellophane, etc. to this plastic film can also be used. The sealing member (23) can be bonded using an adhesive. It is also possible to bond by heat sealing.

  Next, a method for replenishing the contents of the blow bottle (1) as a reusable container will be described with reference to FIG.

In replenishing the contents, first, the overcap of the blow bottle (1) is opened to expose the nozzle cap (12), and the cap of the refill container is removed to expose the sealing member (23).
Then, the refill container is inverted, and the refill container is pushed in such that the outside of the plug (22) of the refill container is inserted along the inside of the dispensing nozzle (121).

Since the sealing member (23) is bonded to the tip of the plug (22) of the refill container, as the plug (22) is pushed in, the tip of the opening (124) first becomes the sealing member ( 23).
Next, with the entry of the dispensing nozzle (121), the sealing member (23) is broken by the tip of the opening portion (124).

The sealing member (23) is broken, the refill container is opened, the contents flow out of the refill container, and are accommodated in the blow bottle (1) through the extraction nozzle (121).
When the sealing member (23) is broken and the content flows out of the refill container, the tip of the plug (22) is fitted inside the pouring nozzle (121). Mostly, the inside of the blow bottle (1) is filled.
Since the contents that have partially flowed out of the dispensing nozzle are reliably filled into the inside of the use container repeatedly through the region surrounded by the cylindrical side wall, they do not spill at this time.

  The blow bottle has a content return channel (122) around the pouring nozzle (121), and a peripheral wall (123) is provided around the content return channel. The contents that have flowed out from the breaking position of (23) flow out into the region surrounded by the peripheral wall. And it fills the inside of the blow bottle (1) which is a use container repeatedly through the flow path (122) for content return in a surrounding wall. For this reason, it does not spill outside the repeated use container.

  The container of the present invention can be widely used as a container for applications requiring refilling in addition to toiletries, liquid detergents, softeners, hand soaps, and the like.
