JP5424148B2 - Combination of continuous use container and refill container - Google Patents

Description

  The present invention relates to a combination of a continuous use container and a refill container for refill contents such as detergents, softeners, bleaches, bathing agents, foods, cosmetics, and medicines. The present invention relates to a combination of a continuous use container and a refill container that suitably fills the refill contents from the refill container with respect to the continuous use container having the output cylinder piece.

  Many dispensing containers are used in which a bowl-shaped dispensing tube piece for dispensing contents is projected from the upper end opening of the container body, and this type of container is accompanied by a weighing function unit. Since it is general, the price is high accordingly.

  For this reason, this type of container shall be used continuously, and the contents to be replenished shall be stored in an inexpensive refill container, and the contents stored in this refill container shall be transferred to the continuous use container. The price is reduced by an amount corresponding to the price of the storage container. In addition, the refill container is environmentally friendly by reducing the amount of resin and reducing the volume.

  When refilling the contents from the refill container to the continuous use container, the refilling of the contents is the pouring of the contents from the refill container to the continuous use container. There was a complaint that the refilling container had to be held until the pouring of the contents was completed, and the refilling operation was troublesome.

  As one of the prior arts for solving this dissatisfaction, the refill contents filled in the repeated use container provided with a transition cap in which a tubular nozzle protrudes from the container opening as shown in Japanese Patent Application Laid-Open No. 2004-099082 are provided. The refilled container stored, with a refill container main body, a bag provided along the edge of the opening of the container, and a detachable fit to the periphery of the opening of the transition cap of the repeated use container fitted into the backup ring, A phytojoint through which the nozzle is removably inserted, an opening of the refill container body that is sealed, an inner lid that is opened and closed by the nozzle inserted through the phytojoint, and an outer cover that covers the outside of the inner lid of the opening of the refill container body The thing of the structure provided is known.

  In the above-described prior art, the inner lid is opened with the phytojoint of the refilling container attached to the transition cap of the reusable container, so that there is no liquid splashing or dripping of the contents, Since the refill container is assembled and held in an inverted posture with respect to the repetitively used container, there is no need to keep holding the refill container during the refilling operation of the contents.

  However, in the above-described prior art, the inner lid that is pushed up by the nozzle to form the refilling opening of the contents has a simple flat plate structure, so the upper end opening of the nozzle that pushes up the inner lid Therefore, there has been a problem that the refilling operation of the contents from the refill container with respect to the reusable container cannot be smoothly achieved.

  That is, since the upper end opening of the nozzle is almost blocked by the inner lid, the contents to be refilled flow through both sides of the nozzle, but this passage repeatedly causes air flow from the use container to the refill container. Since it also serves as an “escape” passage, there is a problem that refilling from the refill contents and the reusable container cannot be smoothly achieved.

JP 2004-099082 A

  Therefore, the present invention was devised to solve the above-mentioned problems in the prior art, and in a combination of a continuous use container having an upright bowl-shaped pouring tube piece and a refill container containing refill contents, Refilling the contents of the refill with the technical problem of preventing the middle plug piece of the refill container side, which is pushed up by the continuous use container side to form the opening, from blocking the upper end opening of the dispensing cylinder piece The purpose is to achieve smooth operation.

The main configuration of the present invention for solving the above technical problem is:
A combination of a continuous use container assembled with a main body cap having an extraction cylinder piece standing from the bottom plate and forming a groove part, and a refill container having a container body for storing the contents for refilling,
Assembling a coupling lid on the mouthpiece of the container body of the refill container,
In this coupling lid, to provide an inner plug piece through a weakened portion on the bottom wall that closes the mouth tube portion of the refill container, and a guide tube fitted into the main body cap of the continuous use container in an inverted posture,
The inner plug piece is configured by abutting a standing portion at the upper peripheral edge of the flat plate-shaped main body,
While providing a pressing piece on the outer surface of the groove bottom wall of the extraction cylinder piece, providing a pushing wall piece on both side walls of the extraction cylinder piece,
A continuous portion of the bottom plate with the extraction cylinder piece and the pressing piece is a thin-walled portion that can be easily bent and deformed;
By the abutment of the poured cylinder piece of the continuous use container, the inner plug piece tilted and displaced in the opening direction while breaking the weakened part to form an opening,
The push-up wall piece hits the inner plug piece due to the inclination of the extraction cylinder piece by the pressing piece pressed against the opening edge of the opening, and the inner plug piece is tilted and displaced to the fully open position,
It is in.

  When the inverted refill container is pushed in while the guide cylinder is inserted into the main body cap from above, the inner stopper piece is weakened by the abutment of the continuously used container against the outlet cylinder piece against the inner stopper piece of the refill container. When the refilling container is pushed into the container for continuous use, the pushing pipe piece is pressed against the opening edge of the opening so that the entire dispensing tube piece opens the inner plug piece. Inclined in the direction, the inner plug piece is pushed up in the opening direction.

  If the pushing of the refill container into the container for further use is further promoted, the tilted displacement of the dispensing cylinder piece further advances and the push-up wall piece comes into contact with the inner plug piece, but in this state, the refill container continues to be used. As the pushing into the container progresses, the push-up wall piece comes into contact with the abutting portion of the inner plug piece and “presses” the inner plug piece in the opening direction. As a part, it tilts and displaces to the fully open posture, and opens the entire opening.

  In a state where the guide tube of the refill container is pushed into the main body cap of the continuous use container, the assembly of the refill container in the inverted posture with respect to the continuous use container is held by the fitting assembly of the guide tube with respect to the main body cap.

Since the inner plug piece is provided on the bottom wall via the weakening portion, the position of the peripheral end portion of the inner plug piece can be accurately opposed to the tip of the extraction tube piece and the push-up wall piece. At the same time, it is easy to sufficiently increase the tilting range. The inclination displacement operation of the entire extraction cylinder piece by the pressing of the pressing piece against the opening edge of the opening is smoothly and smoothly performed by the bending deformation of the thin portion.

  Another configuration of the present invention is such that, in addition to the main configuration described above, the coupling lid of the refill container is covered with a detachable stopper that is detachably assembled.

  In the case where the coupling lid is covered with a detachable stopper that can be detachably attached, it is possible to prevent the middle stopper piece from being accidentally broken and opened, and the refill container reaches the consumer. In the storage / conveyance state, the coupling lid is covered to prevent entry of dust or the like into the coupling lid, so that the refill container as a product can be handled in a sanitary manner.

  In addition to the main configuration described above, another configuration of the present invention is provided with a plurality of split grooves in the upper half portion of the guide tube.

  In the case where the upper half of the guide cylinder is provided with a plurality of split grooves, the elastic reduction of the upper half of the guide cylinder fitted into the main body cap of the continuous use container is facilitated. The fitting assembly with respect to the main body cap is achieved without difficulty.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the main configuration of the present invention, the assembly of the refill container with respect to the continuous use container in the inverted posture is held by the fitting assembly of the guide tube with respect to the main body cap, so that the work of refilling the contents takes time. It will be achieved easily and safely.

  When the inner plug piece is close to the fully open state, the push-up wall piece is in a state of “pushing” the abutting part of the inner plug piece in the opening direction. The entire area can be opened, thereby providing a large flow path for the refill contents.

Further, since the position of the peripheral end portion of the inner plug piece can be accurately opposed to the tip of the dispensing tube piece, the tilt displacement of the inner plug piece can be reliably obtained while breaking the weakened portion. Thus, a reliable refilling operation of the contents can be obtained. Since the tilt displacement operation of the entire dispensing cylinder piece is performed smoothly without difficulty, the tilt displacement operation in the opening direction of the inner plug piece can be performed smoothly.

  In the case where the coupling lid is covered with a detachable stopper that can be detachably attached, the inner stopper piece is prevented from being accidentally broken and opened, so that the safety of the refill container can be ensured, The refill container reaches the consumer's hand, in the storage / transport state, covers the coupling lid and prevents the entry of dust etc. into the coupling lid, so that the refill container as a product can be handled hygienically. This makes it possible to purchase a refill container as a product with peace of mind.

  In the case where a plurality of split grooves are provided in the upper half of the guide cylinder, the fitting assembly of the guide cylinder to the main body cap is achieved without difficulty, so it is impossible to install the refill container upside down on the continuous use container. Can be achieved smoothly.

Embodiments of the present invention will be described below with reference to the drawings.
A refill container 1 (see FIG. 1) according to the present invention is tightly attached to a container body 2 configured in a bottle shape for storing refill contents such as a detergent and a bath agent, and a mouth tube portion 3 of the container body 2. It is comprised from the coupling lid 4 assembled | attached with the undercut.

  The coupling lid 4 has an inner flange-shaped top wall 6 continuously provided from the upper end of the assembled cylinder 5 that is externally fitted to the mouth tube portion 3 of the container body 2 and is undercut coupled, and the outer cylinder is formed on the upper surface of the top wall 6. 7 and the inner cylinder 8 are erected with a space therebetween, and a hanging cylinder 9 is provided at the inner peripheral edge of the top wall 6, and a bottom wall 11 for closing the mouth tube portion 3 is connected to the hanging cylinder 9. In addition, an inner plug piece 12 is provided in the center of the bottom wall 11 via a circular weakened portion 15, with an abutting portion 14 erected on the peripheral edge of the upper surface of the disk-shaped main body portion 13. .

  A slightly thin cylindrical guide tube 16 is fitted and fixed to the inner tube 8, and a plurality of split grooves 17 are provided in the upper half of the guide tube 16 positioned above the inner tube 8. Therefore, the upper half portion of the guide cylinder 16 is easily deformed by a reduced diameter.

  The outer cylinder 7 is detachably fitted and assembled to the outer cylinder 7 in a form that covers the entire guide cylinder 16 so as to cover the entire guide cylinder 16.

  In addition, the seal cylinder piece 10 that is suspended from the lower surface of the top wall 6 and tightly fits into the mouth tube portion 3 of the container body 2 enhances the tight assembly of the coupling lid 4 to the mouth tube portion 3.

  The continuous use container 19 (see FIG. 2) in the present invention is a container cap 20 that is tightly assembled to the mouth 21 of the bottle-shaped container body 20 and is detachably screwed to the body cap 22. It has a measuring cap 34 that opens and closes.

  The main body cap 22 (see FIG. 2) includes a fitting cylinder 23 that fits tightly into the mouth portion 21 of the container body 20, a bowl-shaped extraction cylinder piece 26 that is erected on the bottom plate 24 of the fitting cylinder 23, and a fitting. The top 23 of the cylinder 23 is connected to the upper end of the cylinder 23 and has a top plate 31 in which a mounting cylinder 32 is erected, and a mounting cylinder 33 that is suspended from the outer peripheral end of the top plate 31. Forms a U-shaped groove 27.

  The bottom plate 24 has a tapered wall shape that is inclined downward to a position slightly deviated to one side, and a dispensing cylinder piece 26 is erected on the opening edge of the dispensing opening 25 opened in the center portion thereof. The lowermost part of the bottom plate 24 where the lower end of the opening side portion of the pouring cylinder piece 26 is located is a return port for the contents into the container body 20.

  Further, a pressing piece 29 having a vertical plate rib shape and having an upper end portion as an inclined surface is integrally provided on the outer surface of the groove bottom wall of the pouring cylinder piece 26. A push-up wall piece 28 is integrally provided on both groove side walls of the extraction cylinder piece 26 in a form in which both groove side walls are extended.

  A thin-walled portion 30 (see FIG. 2) which is easily bent and deformed is formed at a portion where the extraction cylinder piece 26 and the pressing piece 29 of the bottom plate 24 are connected, and the opening edge of the opening K where the pressing piece 29 is formed. Thus, the inclined displacement of the one-piece body of the extraction tube piece 26, the push-up wall piece 28, and the pressing piece 29 is performed without difficulty.

  The mounting cylinder 32 is a part for screwing and assembling the measuring cap 34, and the mounting cylinder 33 is a part for undercut coupling the main body cap 22 to the container main body 20.

  The measuring cap 34 (see FIG. 2) includes a measuring tube 35 having a top tube shape in which the lower half is inserted into the fitting tube 23 in a state assembled to the main body cap 22, and a substantially central height position of the measuring tube 35. A flange wall 36 that is provided in the shape of an outer casing from the outside, and a threaded cylinder 37 that is suspended from the peripheral end of the flange wall 36 and is screwed closely to the mounting cylinder 32.

Next, the refilling operation of the contents from the refill container 1 to the continuous use container 19 will be described.
The guide cylinder 16 of the refill container 1 that has been turned upside down by removing the stopper plug 18 is fitted and assembled into the insertion cylinder 23 of the main body cap 22 of the continuous use container 19 in the upright position with the measurement cap 34 removed (FIG. 3). See) and go.

  The assembled posture of the refill container 1 with respect to the continuous use container 19 is achieved by being guided by the insertion of the guide cylinder 16 with respect to the insertion cylinder 23. Therefore, as the insertion of the guide cylinder 16 into the insertion cylinder 23 progresses, the continuous use container 19 The force which maintains the assembly | attachment in the inverted posture of the refill container 1 with respect to is strengthened.

  In the case of the illustrated embodiment, the fitting cylinder 23 has a cylindrical structure whose diameter is reduced downward, so that the tightening force acting on the guide cylinder 16 from the fitting cylinder 23 increases as the insertion of the guide cylinder 16 into the fitting cylinder 23 proceeds. However, since the guide cylinder 16 can be deformed with a reduced diameter by the action of the dividing groove 17, the fitting assembly of the guide cylinder 16 with respect to the insertion cylinder 23 is achieved without difficulty and stably.

  With the fitting assembly of the guide cylinder 16 with respect to the insertion cylinder 23, the tip of the extraction cylinder piece 26 abuts against the abutting portion 14 of the inner plug piece 12 or the bottom wall 11 near the weakening portion 15 (see FIG. 3), and the weakening portion 15 A breaking force is applied to the surface.

  When the fitting assembly of the guide cylinder 16 with respect to the insertion cylinder 23 further proceeds, first, the inner plug piece 12 is pushed upward by the action of the pushing-up force from the dispensing cylinder piece 26, and the tilting displacement is performed while breaking the weakened portion 15. Then, the opening K starts to be formed in the bottom wall 11.

  When the assembly of the guide cylinder 16 with respect to the insertion cylinder 23 is pushed forward, the extraction cylinder piece 26 is inclined in the opening direction by the pressing force (see arrow A in FIG. 5) accompanying the pressing of the pressing piece 29 against the opening edge of the opening K. Since the inner plug piece 12 is pushed up while being displaced, the inner plug piece 12 is further tilted and displaced in the “open” direction with the rear weakened portion 15 that is not broken as the “hinge”.

  In the middle of the displacement displacement of the inner plug piece 12 in the opening direction, the portion that applies the pushing force to the inner plug piece 12 is switched from the dispensing cylinder piece 26 to the pushing wall piece 28. In exchange, the tilting displacement of the inner plug piece 12 in the opening direction proceeds rapidly.

  At the final stage of assembly of the guide cylinder 16 with respect to the insertion cylinder 23, the push-up wall piece 28 is in a state in which a pressing force is applied to the abutting portion 14 of the inner plug piece 12, so the opening angle of the inner plug piece 12 is 90 ° or more (see FIG. 4), but in this state, the push-up wall piece 28 has an opening edge of the opening K due to the inclined displacement of the extraction cylinder piece 26 due to the action of the pressing force (see arrow A in FIG. 5). 5 and receives a pressing force (see arrow B in FIG. 5), and the distance between the two pushing wall pieces 28 is changed from the two-dot chain line shown in FIG. Causes a further pressing force to be applied to the abutting portion 14, and the inner plug piece 12 is tilted and displaced in the opening direction by that amount, and the entire opening K is completely opened.

  In the case of the illustrated embodiment, the abutting portion 14 is configured in a short cylindrical piece shape having a low protruding height and is difficult to be deformed, but the structure of the abutting portion 14 is not specified as a short cylindrical piece shape, It may be composed of an elastic plate piece.

  As shown in FIG. 5, the formed opening K is not blocked by the tilted and displaced inner plug piece 12, and the entire area thereof is sufficiently opened to provide a sufficient flow path area. As a result, the contents N can be refilled quickly and smoothly.

  Since the inside of the opening K is partitioned by the extraction cylinder piece 26, the contents N pass through the opening K area portion (for example, the groove portion 27 portion) that easily flows down, and the replacement air is supplied to the other opening K. By passing through the area portion, a smooth refilling operation of the contents N can be obtained without causing “breathing”.

  In the case of the illustrated embodiment, as shown in FIG. 4, the posture of the refill container 1 with respect to the continuous use container 19 is not limited to that of the refill container 1 with respect to the fit cylinder 23 of the guide cylinder 16, but also the refill container 1. Since the outer cylinder 7 is also held by being fitted to the mounting cylinder 32 of the continuous use container 19, the assembly of the refill container 1 in the inverted posture with respect to the continuous use container 19 is more stable. Will be maintained.

  As described above, the combination of the container for continuous use and the refill container according to the present invention can form a refill opening sufficiently large, and a technique for refilling with only one opening that can be formed. As such, a wide range of usage can be expected.
