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.

  Containers such as liquid detergents need to be weighed and taken out each time they are used, so a rigid plastic container with a spout nozzle at the spout is provided to make it easier to pour into a measuring cup. It is used as a container for repeated use. 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.

  These rigid containers that are used repeatedly are designed so that they can be easily poured out. Therefore, they do not necessarily take into account the convenience of refilling operations to replenish the contents from the refilling containers. It was.

  The refilling container can be opened using the dispensing nozzle provided in the container to be used repeatedly, and the refilling container becomes independent during refilling, so the operator does not have to hold it by hand. Refill containers have been proposed. 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. The refill container is inverted, and the coupling member is repeatedly screwed to the opening of the container for use (see Patent Document 1).

  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 is a problem in that the container sealing member may be broken during this operation and the contents may spill out.

  On the other hand, a container in which a reusable container performs a refilling operation using a dispensing nozzle has also been proposed (see Patent Documents 2 and 3). The refill containers described in Patent Document 2 and Patent Document 3 have a sealing member or a seal plate at the tip thereof, so that the contents do not spill even when inverted. On the other hand, the repeated use container is provided with a pouring nozzle at the center thereof, and a cylindrical side wall is provided so as to surround the pouring nozzle. And in the state which inverted the refill container, the extraction nozzle of a use container is repeatedly pushed in into the opening part, and a sealing member or a sealing board is fractured | ruptured and opened by this extraction nozzle front-end | tip. The contents flow out of the opening and are repeatedly stored in the container. At this time, since the pouring nozzle is surrounded by the cylindrical side wall, the contents are not spilled. Further, the refill container in the inverted state can be supported independently by the opening into which the pouring nozzle is inserted, and there is no need for the operator to assist by hand.

  By the way, the repeated use container described in Patent Documents 2 and 3 is used by pushing the pouring nozzle into the opening of the refill container and breaking the sealing member or the seal plate. When the diameter is small, the dispensing nozzle cannot be pushed in. For example, when the refill container has a small-diameter plug, it is difficult to push the pouring nozzle into the plug.

  Therefore, the present invention can be applied to a refill container having such a small-diameter opening, and an object thereof is to provide a reusable container that can be replenished without spilling the contents by a simple operation.

That is, the invention described in claim 1 is a nozzle cap that is attached to the opening of the container body and has a nozzle for pouring, and the container body with the nozzle cap is replenished with the contents from the refill container. In the nozzle cap to be used repeatedly,
The shape of the pouring nozzle is a cylinder having a slit in a part thereof, and an erecting opening portion for breaking and opening the sealing plate of the refill container is erected inside the cylindrical pouring nozzle. It is the nozzle cap characterized by having carried out.

  According to this repetitive container, when refilling the contents, first, the refill container is inverted, and the opening of the refill container is inserted through the inside of the dispensing nozzle, so that the seal plate disposed at the refill container opening is The seal plate is broken by bringing the leading end of the standing upright portion into contact. The contents in the refill container flow out from the broken portion, but the surroundings are surrounded by the cylindrical pouring nozzle, so the contents do not flow out of the cylindrical pouring nozzle.

  Thus, since the opening part of the refill container is inserted through the inside of the extraction nozzle and opened, even if it has a small-diameter plug, it can be easily opened. Moreover, since the refill container is opened only when it comes into contact with the tip of the opening stand, there is no need to open the refill container in advance, and there is no risk of accidental spilling. And most of the contents which flowed out by opening are filled into the use container repeatedly through the slit from the dispensing nozzle.

  In addition, in the case where the periphery of the pouring nozzle has a peripheral wall surrounding it, even when the contents flow out of the pouring nozzle, the region sandwiched between the pouring nozzle and the peripheral wall is used as a flow path. The container is repeatedly filled from the slit through the flow path. For this reason, it does not spill out of the container for repeated use.

  Next, the invention according to claim 2 clarifies that the opening of the refill container can be inserted into the pouring nozzle. Further, according to the third aspect of the present invention, when the opening of the refilling container is inserted into the dispensing nozzle, there is no looseness between the refilling container opening and the dispensing nozzle. These can be made independent without requiring an auxiliary operation in a state where the portion is inserted into the inside of the dispensing nozzle.

  That is, the invention described in claim 2 is the nozzle cap according to claim 1, wherein the cylindrical pouring nozzle has an inner diameter that can accommodate the opening of the refill container. The invention according to claim 3 is the nozzle cap according to claim 2, characterized in that the inner diameter of the cylindrical pouring nozzle is large enough to accommodate the opening of the refill container. is there.

The invention according to claim 4 clarifies that when the opening of the refill container is inserted into the inside of the pouring nozzle, the opening standing portion does not become an obstacle to the insertion. The nozzle cap according to any one of claims 1 to 3, further comprising a gap for inserting a wall constituting the opening of the opening between the opening upright portion and the extraction nozzle.

  The invention according to claim 5 is characterized in that a height of the pouring nozzle is the same as or higher than a height of a tip of the standing upright portion for opening. It is a nozzle cap. As described above, the seal plate abuts against the tip of the opening upright portion and breaks, and flows out from the break portion. However, in the invention according to claim 5, the nozzle is higher than the tip of the dispensing nozzle. The outflow position is an area surrounded by the dispensing nozzle, and the outflow of the contents outside the area can be prevented.

  The invention according to claim 6 is characterized in that a tip of the standing upright portion is located on the side opposite to the slit when viewed from the center of the cylindrical pouring nozzle. It is a nozzle cap in any one of -5, The invention of Claim 7 inclines so that the ridgeline of the said standing part for opening may become low toward the said slit, It is characterized by the above-mentioned. Item 7. The nozzle cap according to Item 6. According to the sixth and seventh aspects of the present invention, the contact between the seal plate and the tip of the standing upright portion is started at a position opposite to the slit, and therefore the breakage of the seal plate is also opposite to the slit. Start from the position. This broken portion gradually spreads toward the slit, resulting in the broken seal plate being moved to the slit position. And since a sealing plate is accommodated in the slit provided in the cylindrical extraction nozzle, it does not fall into the inside of a container for repeated use.

  The invention according to claim 8 clarifies this point, that is, when the seal plate of the refill container is broken, a gap that accommodates the broken seal plate is formed as the opening upright portion and the slit. The nozzle cap according to any one of claims 1 to 7, wherein the nozzle cap is between the two.

  Next, the invention according to claim 9 is the nozzle cap according to any one of claims 1 to 8, wherein a cross-sectional shape of the standing portion for opening is a cross shape.

  A tenth aspect of the present invention relates to a repeated use container equipped with the nozzle cap according to any one of the first to ninth aspects.

  According to the present invention, even if the refill container has a small-diameter opening, it can be replenished by a simple operation without spilling the contents.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional view of an essential part of a repeated use container according to the first embodiment of the present invention, and FIG. 2 is a perspective view of a nozzle cap.
FIG. 3 is for explaining the technical relationship between the nozzle cap pouring nozzle 121 and the standing upright part, FIG. 3 (a) is a cross-sectional view of the main part, and FIG. 3 (b) is required. FIG.

  In this example, the repeated use container body 11 is a plastic blow bottle, and a nozzle cap 12 is attached to the opening thereof. In addition, it is normal to cover the nozzle cap 12 with an overcap (not shown) to prevent contamination of the nozzle cap 12.

  The nozzle cap 12 has a dispensing nozzle 121 at the center thereof. As can be seen from FIG. 3A, the dispensing nozzle 121 has a cylindrical shape having a slit 121 a in a part thereof, and the inside thereof is a cavity that communicates with the inside of the container body 11 for repeated use. And by tilting the container main body 11 repeatedly, the contents are guided by the pouring nozzle 121 and poured out to the outside. In addition, when pouring, air flows into the blow bottle 11 through the slit 121a.

  The nozzle cap 12 has a content return channel 124 surrounding the pouring nozzle 121 erected at the center, and a peripheral wall 123 surrounding the periphery. In this way, the content returning flow path 124 sandwiched between the pouring nozzle 121 and the peripheral wall 123 communicates with the slit 121a downstream. 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 returning channel 124, and repeatedly through the slit 121a, inside the container body 11 to be used. Return to. For this reason, the contents adhering to the tip of the pouring nozzle 121 are not repeatedly spilled to the outside of the container body 11 and the surroundings are not soiled. In addition, the height is configured to be lower than the pouring nozzle 121 so that the peripheral wall 123 does not interfere with the pouring operation when the contents are poured by repeatedly tilting the container body 11 to be used.

  The inner diameter 121r of the dispensing nozzle 121 needs to be large enough to accommodate an opening 221 of the refill container 2 described later. In this example, the inner diameter 121r of the dispensing nozzle 121 is sufficiently larger than the outer diameter 221r of the opening 221 of the refill container 2, so that the opening 221 of the refill container 2 can be inserted with a margin.

  Next, a standing upright portion 122 is erected within the dispensing nozzle 121. In this example, the standing portion 122 for opening has a cross-shaped cross section, and the lower portion is connected to the inner wall of the cylindrical pouring nozzle 121 via the connection portion 122b. The opening upright portion 122 has a role of breaking the seal plate 222 that closes the opening portion 221 when the opening portion 221 of the refill container 2 is inserted into the pouring nozzle 121. By this breakage, the refill container 2 is opened, and the contents are repeatedly transferred from the refill container 2 to the use container 1.

  Next, in FIG. 3A, a two-dot chain line 122r indicates a circumference connecting the outer periphery of the standing upright portion 122, and between this circumference 122r and the dispensing nozzle 121, that is, the standing upright portion for opening. A sufficient gap 12 a is provided between 122 and the dispensing nozzle 121. In other words, the diameter of the circumference 122r that connects the outer periphery of the standing upright portion 122 is smaller than the inner diameter of the opening 221 of the refill container 2. For this reason, when inserting the opening part of the refilling container 2 in the inside of the pouring nozzle 121, the wall body which comprises the opening part 221 of the refilling container 2 is inserted between the standing part 122 for opening and the pouring nozzle 121 can do. Note that a connecting portion 122b is provided at the lower part of the opening upright portion 122, and the gap 12a is blocked.

Next, as can be seen from FIG. 3A, the gap 12a is widely provided in the direction in which the slit 121a is present. This is because the seal plate 222 broken by the opening upright portion 122 is accommodated in the gap 12a at this position and fixed. For this reason, in the direction in which the slit 121a exists, the gap 1
2a is preferably configured to be wider than the thickness of the seal plate 222.

  Next, as can be seen from FIG. 1 and FIG. 3B, the ridgeline 122c of the standing upright portion 122 is inclined so as to become lower toward the slit 121a. And the front-end | tip 122a is located in the opposite side to the slit 121a seeing from the center of the cylindrical pouring nozzle 121, and has a sharply sharp projection shape at this position. For this reason, when the opening part of the refill container 2 is inserted into the inside of the pouring nozzle 121, the seal plate 222 and the standing upright part 122 start to contact from the tip 122a. And since this front-end | tip 122a has a sharp-pointed protrusion shape, the force concentrates on this front-end | tip 122a, and the sealing board 222 can be fractured | ruptured easily. Thus, the breakage of the seal plate 222 starts from this position, and the breakage portion gradually spreads toward the slit 121a as the opening upright portion 122 enters, and the broken seal plate 222 rises to the position of the slit 121a. It is put away.

  Next, in this example, the height of the dispensing nozzle 121 is configured to be substantially the same as the height of the tip 122a of the standing upright portion 122 for opening. For this reason, the position where the breakage of the seal plate 222 of the refill container 2 starts is also the same as the height of the dispensing nozzle 121. And since the outflow position (namely, fracture | rupture position) is surrounded by the pouring nozzle 121, the outflow of the content which flows out from this fracture | rupture part can be prevented.

  In addition, since the dispensing nozzle 121 is provided with the slit 121a, it does not mean that there is no possibility of the contents leaking from the outflow position (breaking position) to the outside of the dispensing nozzle 121 through the slit 121a. However, since the outflow position (breaking position) is located on the side opposite to the slit 121a, there is almost no content leaking out of the pouring nozzle 121 through the slit 121a. Further, even when leaking to the outside of the pouring nozzle 121 through the slit 121 a in this way, the inside of the container 1 is repeatedly used through the pouring nozzle 121 and the content return channel 124 sandwiched between the peripheral walls 123. Therefore, there is virtually no content that spills out of the container 1 for repeated use.

  Next, FIG. 4 has shown the principal part longitudinal cross-sectional view of the refill container 2 which concerns on the 1st Embodiment of this invention. In this example, the refill container 2 is composed of a refill container main body (bag) and a spout 22 attached to the opening of the refill container, and the spout 22 is a sleeve 23 for fixing the refill container main body (bag). The sleeve 23 is sandwiched between the front film 21a and the back film 21b constituting the refill container main body (bag), and is mounted by heat sealing.

  The spigot 22 is provided with a small-diameter cylindrical opening 221 that can be inserted into the pouring nozzle 121, and a thread 22a for screwing a cap (not shown) is provided on the outer periphery thereof. Has been. And the inside of the cylindrical opening part 221 comprises the flow path through which the contents flow out from the refill container 2. A seal plate 222 is disposed in the middle of the flow path to close the flow path. Around the seal plate 222, there is provided an opening score 222a composed of a thin portion, and when the seal plate 222 is pressed by the opening standing portion 122, the opening score 222a is broken, The flow path is configured to be opened. For this reason, it is desirable that the diameter 222r of the opening score 222a is the same as or larger than the diameter of the circle 122r that connects the outer periphery of the opening standing portion 122.

  It is desirable that the opening score 222a formed of a thin portion is provided on the seal plate 222 except for a position close to the slit 121a. That is, it is desirable that the opening score 222a is not provided at a position close to the slit 121a. As described above, the opening score 222a begins to break at a position opposite to the slit 121a, and the seal plate 222 that has been broken with the entrance of the opening standing portion 122 rises and gradually shifts to the position of the slit 121a. Therefore, when the opening score 222a is provided on the entire circumference of the seal plate 222, the seal plate 222 is separated from the cylindrical opening 221 by breaking the opening score 222a over the entire circumference. There is a risk of falling into the inside of the container body 11 repeatedly used. On the other hand, when there is no opening score 222a at a position close to the slit 121a, the seal plate 222 is not separated, and therefore does not fall into the inside of the container body 11 for repeated use. Moreover, when the refill container 2 is removed after the replenishment of the contents to the repeated use container 1 is completed, the seal plate 222 can be removed together.

  Next, since it is necessary to insert the cylindrical opening 221 into the inside of the pouring nozzle 121 and insert the standing upright part 122 for opening into the cylindrical opening 221, the cylindrical opening 221 is configured. The wall body must be able to be inserted into the gap 12a between the opening upright portion 122 and the dispensing nozzle 121. In this example, the outer diameter 221r of the cylindrical opening 221 is sufficiently smaller than the inner diameter 121r of the dispensing nozzle 121. For this reason, when the opening standing part 122 is inserted into the cylindrical opening 221 and the opening score 222a is broken, a sufficient clearance is provided between the cylindrical opening 221 and the dispensing nozzle 121. Can do.

  Using the refill container 2, the contents can be replenished to the use container 1 repeatedly in the following manner. FIG. 5 is a longitudinal sectional view of an essential part showing a replenishing method.

  That is, the refill container 2 is inverted, the cylindrical opening 221 is directed downward, and the cylindrical opening 221 is repeatedly inserted into the dispensing nozzle 121 of the use container 1. At this time, the standing upright portion 122 is inserted into the cylindrical opening portion 221. In other words, the cylindrical opening 221 is repeatedly inserted into the inside of the dispensing nozzle 121 of the use container 1 such that the cylindrical opening 221 is sandwiched between the opening upright part 122 of the repeated use container 1 and the dispensing nozzle 121. To be inserted. At this time, there is sufficient clearance between the cylindrical opening 221 and the dispensing nozzle 121.

  Then, when the refill container 2 is pushed downward while the refill container 2 is maintained in an inverted state so that the opening erecting part 122 enters the cylindrical opening 221, the front end 122 a of the unraveling rising part 122. Hits the seal plate 222, breaks the opening score 222a, and opens the flow path of the refill container 2. At this time, since the leading end 122a of the standing upright portion 122 is located on the opposite side to the slit 121a, the opening score 222a also starts to break from the position opposite to the slit 121a. And since the ridgeline 122c of the standing upright part 122 is inclined so as to become lower toward the slit 121a, the broken part gradually spreads toward the slit 121a as the standing upright part 122 enters. At the same time, the broken seal plate 222 rises up and is offset so as to rotate around a position close to the slit 121a (see FIG. 5). The gap 12a is widely provided in the direction of the slit 121a, and the gap 12a at this position is formed wider than the thickness of the seal plate 222. Therefore, the rising seal plate 222 is accommodated in the gap 12a. Can be fixed. At this time, since the opening score 222a is not provided at a position close to the slit 121a, the broken seal plate 222 only rises around this position, and the cylindrical opening 221 There is no separation from.

Further, as described above, the flow path of the refill container 2 is opened from the position of the front end 122a of the opening stand 122, and the outflow starts from this position, but this outflow position (breaking position) is almost the same height. Since it is surrounded by the pouring nozzle 121 and is located on the opposite side of the slit 121a, most of the contents flowing out from the outflow position (breaking position) pass through the pouring nozzle 121. The inside of the repeated use container body 11 is replenished. Further, the contents leaking outside the pouring nozzle 121 are repeatedly replenished into the inside of the use container 1 through the contents returning flow path 124 sandwiched between the pouring nozzle 121 and the peripheral wall 123.

  The opening upright portion 122 is not limited to the one having a cross-shaped cross section, but when the opening upright portion 122 is inserted into the cylindrical opening portion 221 of the refill container 2, the opening upright portion 122 is opened. In order to reduce the contact area between the side wall 122 and the inner wall of the standing upright portion 122 and facilitate insertion thereof, it is desirable that the cross-sectional shape is a cross shape.

  Further, in the first embodiment, the height of the dispensing nozzle 121 is configured to be substantially the same as the height of the tip 122a of the unraveling stand 122, but the tip 122a of the unraveling stand 122 is formed. It may be higher. Also in this case, when the seal plate 222 is broken and opened at the front end 122a of the standing upright portion 122, the outflow position (breakage position) can be surrounded by the pouring nozzle 121.

  Next, in the first embodiment, the inner diameter 121r of the dispensing nozzle 121 is configured to be sufficiently larger than the outer diameter 221r of the cylindrical opening 221 of the refill container 2, but the second embodiment of the present invention. The nozzle cap 12 according to the embodiment has a size such that the inner diameter 121r of the dispensing nozzle 121 can accommodate the cylindrical opening 221 of the refill container 2 without any gap. FIG. 6 is a longitudinal sectional view of an essential part showing a method of replenishing the contents of the container 1 for repeated use using the nozzle cap 12.

  As can be seen from FIG. 6, when the cylindrical opening 221 is inserted into the extraction nozzle 121 according to the second embodiment, there is no looseness between the cylindrical opening 221 and the extraction nozzle 121. Therefore, the refill container 2 can be stably inverted without requiring an operator's assistance. For this reason, after refilling the refill container 2, the cylindrical opening 221 is allowed to stand in a state where it is inserted through the dispensing nozzle 121, so that the contents of the reusable container 1 can be repeatedly stored without requiring the operator's assistance. It becomes possible to replenish things.

  When the inner diameter 121r of the dispensing nozzle 121 and the outer diameter 221r of the cylindrical opening 221 of the refill container 2 are substantially the same as described above, positioning protrusions or positioning ribs are formed on the inner wall of the dispensing nozzle 121. Can be used. In this case, it is desirable to use the plug 22 of the refill container 2 having a guide groove corresponding to the positioning protrusion or the positioning rib on the outer wall of the cylindrical opening 221. In this case, when the cylindrical opening 221 is inserted through the dispensing nozzle 121, the positional relationship between the two can be uniquely determined by making the positioning protrusions and positioning ribs correspond to the guide grooves. For this reason, for example, it is possible to reliably position so that the part where the opening score 222a does not exist is close to the slit 121a.

  Of course, it is also possible to use the nozzle cap 12 provided with a guide groove on the inner wall of the dispensing nozzle 121. In this case, a positioning projection or a positioning rib corresponding to the guide groove is provided in the cylindrical opening 221. It is desirable to use the spigot 22 provided on the outer wall.

  In order to make the inner diameter 121r of the pouring nozzle 121 and the outer diameter 221r of the cylindrical opening 221 of the refilling container 2 substantially the same, a stopper-fitting type plug is used as the plug 22 of the refilling container 2. It is desirable to do. The plug 22 in FIG. 6 is a stopper fitting type plug, and has a recess 22b on the outer peripheral surface of the cylindrical opening 221 but does not have a screw 22a. For this reason, the cylindrical opening part 221 can be penetrated by the extraction nozzle 121, without producing looseness between both.

By the way, the nozzle cap 12 according to the present invention uses a thermoplastic resin such as a polyethylene resin, a polypropylene resin, a polyester resin and the like by an injection molding method.
It can be molded by one-time molding. In order to improve durability, it is desirable to use a resin material with high hardness. For example, polypropylene resin.

  Further, the spigot 22 can be formed in the same manner using an injection molding method using a thermoplastic resin such as polyethylene resin, polypropylene resin, polyester resin or the like.

  Further, as the repeated container body 11, an arbitrary container can be used instead of the plastic blow bottle.

  Further, as the refill container body, any container can be used instead of the packaging bag, but it is desirable to use a flexible packaging bag. When the refill container body is a flexible packaging bag, when the cylindrical opening 221 is inserted through the extraction nozzle 121 and left to stand, the packaging bag is naturally crushed, and the contents quickly and repeatedly move to the use container. Therefore, it is possible to replenish the used container quickly and repeatedly. As the packaging bag, a three-side seal bag, a four-side seal bag, or the like can be used. A standing pouch that is heat-sealed by sandwiching a folded bottom film between the front film 21a and the back film 21b can also be used.
