JP5541568B2 - 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 content liquid 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 cylinder piece for dispensing the content liquid 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 is to be used continuously, and the content liquid to be replenished is stored in an inexpensive refill container, and the content liquid stored in this refill container is 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 content liquid from this refill container to the continuous use container, this refilling of the content liquid will pour the content liquid from the refill container into the continuous use container. There was a complaint that the refilling container had to be held until the pouring of the contents liquid was finished, and the refilling work was troublesome.

  As one of the prior arts for solving this dissatisfaction, a refilling content liquid filled in a repeated use container provided with a transition cap in which a tubular nozzle protrudes from a container opening as shown in Japanese Patent Application Laid-Open No. 2004-099082. A refillable container that has a refillable container body and a backup ring that is provided along the edge of the opening of the container, and that is removably fitted to the periphery of the opening of the transition cap of the container that is used repeatedly. A phytojoint through which the nozzle is removably inserted, an opening of the refill container body, 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 refill container body The thing of the structure provided with is known.

  In the above prior art, the inner lid is opened with the phytojoint of the refill container attached to the transition cap of the repetitively used container, so there is no liquid splashing or dripping of the content liquid, Since the refill container is assembled and held in the 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 content liquid.

  However, in the above-described prior art, the inner lid that is pushed up by the nozzle to form the refill port of the content liquid has a simple flat plate structure, and therefore 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 content liquid from the refill container with respect to the reusable container cannot be achieved smoothly.

  In other words, since the upper end opening of the nozzle is almost closed by the inner lid, the liquid to be refilled flows 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 has been a problem that refilling from the refilled content liquid and the reusable container cannot be smoothly achieved.

JP 2004-099082 A

  Therefore, the present invention was devised to solve the above-described problems in the prior art, and in a combination of a continuous use container having a stand-up pouring cylinder piece and a refill container containing the refill content liquid, It is a technical problem to obtain a stable refilling operation and to obtain a preferable disposal state of the refilling container, and to refill the refill content liquid well and to obtain a good disposal process of the refilling container after the refilling And

The main configuration of the present invention for solving the above technical problem is:
The container body has a continuous use container with a main body cap having a pouring cylinder piece standing up and forming a pouring passage , and the refill container is assembled to the continuous use container . A combination of a refill container that allows refilling and a container for continuous use ;
The body of the casing is formed into a thin wall that can be deformed and reduced in accordance with the internal pressure reduction by the pouring of the content liquid flowing down naturally.
Providing a fitting cylinder fitted into the extraction cylinder piece of the continuous use container on the coupling lid of the refill container, and providing an inner plug for closing the fitting cylinder;
Providing an assembled ring having a pair of beam pieces extending in a protruding shape toward the center of the ring on the inner peripheral surface of the extraction tube piece;
The push-up body that pushes up and opens the inner plug of the fitting cylinder fitted and assembled at the ends of the pair of beam pieces is erected in a state having a height difference,
It is in.

  When the inverted refill container is pushed in while the fitting cylinder is inserted into the extraction cylinder piece of the continuous use container from above, the fitting cylinder is inserted into the extraction cylinder piece, so that it can be attached to the continuous use container. Assembling in the inverted posture of the refill container will be maintained, and further pushing the fitting tube into the extraction tube piece will cause the continuous use container push-up body to abut against the inner plug of the refill container, The inner plug is tilted and displaced while being pushed up to form an opening.

  When a casing that is almost full and filled with content liquid is opened in an inverted position with the mouth tube part fixed, the casing will pour out a certain amount of content liquid by its own weight without allowing outside air to enter the interior. At this time, the volume of the body part is reduced and deformed as the content liquid is poured out.

  At this time, since the refill container is maintained in the inverted posture, the combination of the continuously used container and the refill container maintains a stable self-supporting state while the volumetric deformation is progressing.

In this state, the dispensing of the content liquid proceeds, and when the volume reduction deformation of the body of the casing proceeds to some extent, the resistance generated along with the volume reduction deformation of the body of the casing temporarily causes Although the content liquid is automatically dispensed by its own weight, the external air is immediately sucked into the air bubbles from the opening, and the content liquid is continuously poured out in a breath, thereby completing the refilling of the content liquid. Let
At this time, a crushed ridge due to volume reduction deformation is attached to the body of the casing.

  In this way, the refilling of the content liquid is completed in accordance with the volume reduction deformation of the refill container due to the natural dispensing of the content liquid. Therefore, when the refilling of the content liquid is completed, the body of the refill container is reduced in volume. When the refill container is removed from the container for continuous use and discarded, the refill container is crushed from above so that it is almost completely crushed, thereby sufficiently reducing the volume.

  In another configuration of the present invention, in addition to the main configuration described above, the volume reduction deformation of the body portion of the housing is a deformation that is reduced in the vertical direction while being folded and deformed in a twisted manner.

  If the volume reduction deformation of the body of the housing is a deformation that shrinks in the vertical direction while folding and deforming in a twisted manner, it will be folded into a twist when the volume reduction deformation of the body of the housing proceeds to some extent. Deformed portions that shrink in the vertical direction while deforming come into contact with each other, and resistance to volumetric deformation in the body portion is generated. As a result, the volumetric deformation of the body of the casing and the dispensing of the content liquid are temporarily stopped, but the content liquid is immediately poured out. In this case, the volume reduction deformation of the body portion is a twist-like folding deformation, and therefore the longitudinal reduction deformation of the body portion proceeds while maintaining an upright posture.

  Another configuration of the present invention is such that, in addition to the main configuration described above, an inner plug is provided at the tip of the fitting tube.

  In the case where the inner plug is provided at the tip of the fitting tube, the inner plug can be positioned close to the opening of the fitting tube, so that the inner plug faces the push-up body. In addition to being easy, the push-up body can be opposed to the inner plug without deeply penetrating into the fitting cylinder, so that the structure of the push-up body can be simplified correspondingly.

Another configuration of the present invention, in addition to the main structure described above, the inner plug the higher lifting piece and pushed Gaité open portion, to the release position the inner plug the lower lifting piece minute parts holding the, those.

  If the push-up piece has a part that pushes up and opens the inner plug and a part that holds the inner plug in the release position, the push-up piece is pushed up by the part that the push-up piece opens and tilted and released. Since the inner plug is continuously held by the portion that holds the open posture, the flow passage area of the formed extraction channel can be stably and constantly maintained.

  In addition to the main configuration described above, another configuration of the present invention is that the inner plug is attached to the fitting cylinder with a hinge.

  In the case where the inner stopper is attached to the fitting cylinder with a hinge, the opening swing direction of the inner stopper can be regulated to be constant, so that the opening and tilting operation of the inner stopper is constant and stable. can do.

Since the present invention has the above-described configuration, the following effects can be obtained.
In the main configuration of the present invention, the volume reduction deformation of the casing due to the natural flow due to the weight of the refill content liquid is stably maintained in the inverted state of the refill container with respect to the continuous use container. In addition, the self-supporting function of the combination of the continuous use container and the refill container is stably maintained, so that refilling of the content liquid can be stably achieved without touching.

  The casing after the content liquid has been poured out is in a state in which its body has been deformed and deformed to some extent. By applying a crushing force to the casing in the vertical direction, the casing is removed. The volume can be reduced and deformed in a crushed shape in the vertical direction easily, whereby the disposal of the housing can be carried out suitably and efficiently.

  If the volume reduction deformation of the body of the housing is a deformation that shrinks in the vertical direction while folding and deforming in a twisted manner, the shrinking deformation in the vertical direction is upright because it proceeds while being deformed in a twisted manner. Progressing in a state in which the posture is maintained, thereby maintaining the upright posture stably, and the reduction deformation in the vertical direction becomes constant.

  In the case where the inner plug is provided at the distal end of the fitting cylinder, the structure of the push-up body can be simplified, so that the structure of the continuous use container can be simplified.

  If the push-up piece has a part that pushes up and opens the inner plug, and a part that holds the inner plug in the release posture, the flow passage area of the formed extraction passage is stably Since it can hold | maintain constant, the natural extraction operation | movement with a sufficient precision of the refilling content liquid can be obtained, and the reliable refilling operation | movement of a content liquid can be obtained.

  In the case where the inner plug is provided with a hinge and is assembled to the fitting cylinder, the opening inclination direction of the inner plug is constant, so that a stable and accurate opening operation can be obtained.

Embodiments of the present invention will be described below with reference to the drawings.
The refill container A (see FIG. 1) in the present invention connects the mouth tube portion 2 to the upper end of the body portion 4 having the bottom portion 5 for containing the refilling content liquid N such as a detergent or a bathing agent via the shoulder portion 3. It is comprised from the housing 1 which was installed and comprised in the shape of a bottle, and the coupling lid 20 screwed and assembled | attached to the mouth tube part 2 of this housing 1 closely. The assembly of the coupling lid 20 to the mouth tube portion 2 is not limited to screwing, but may be undercut coupling.

  The casing 1 is a biaxially stretched blow-molded product made of polypropylene resin, has a total height of 125 mm, an outer diameter of the trunk portion 4 of 70 mm, and a capacity of 300 ml. A ridge line 12 is formed, and the peripheral wall is configured by connecting adjacent ridge lines 12 with three panel walls 11 having a circular cross-sectional shape.

  Each panel wall 11 is formed with a valley-like crease line 13 that diagonally connects the upper end portion of the ridge line 12 positioned at one side end and the lower end portion of the ridge line 12 positioned at the other side end portion. These three crease lines 13 are inclined in parallel in the circumferential direction.

  Here, the three ridge lines 12 are arranged at the vertices of a regular triangle, and function as pillars with respect to a lateral force acting on the housing 1. Moreover, the peripheral wall of this trunk | drum 4 is formed so that it may reduce in diameter toward a center height position from an upper end and a lower end except for the ridgeline 12 part.

  Further, in the case 1 of the present embodiment, the inclination angle of the crease line 13 with respect to the vertical direction is about 45 °. This inclination angle can be determined as appropriate in consideration of the shape of the casing and the volume reduction deformation of the peripheral wall of the body portion 4 relating to the smooth pouring of the content liquid.

  The coupling lid 20 (refer to FIG. 1 and FIG. 2 below) is fitted from the upper end of the assembled cylinder 21 that is externally fitted to the mouth tube portion 2 of the casing 1 and is screwed together through an inner flange-shaped top wall. The cylinder 22 is constructed by standing upright, and the engagement cylinder 23 is provided on the inner periphery of the upper end opening of the engagement cylinder 22, and the engagement cylinder 23 is closely engaged with the engagement cylinder 23. An inner plug 24 for closing the cylinder 22 is assembled. The assembly of the coupling lid 20 to the mouth tube portion 2 is not limited to screwing but may be undercut.

  The assembled cylinder 21 has a linear cylindrical shape, and has a strength capable of stably holding the refill container A in the inverted posture in the state of being assembled in the inverted posture on the continuous use container B side. It has become a thing.

  In addition, the cylinder piece which is provided in a state where the assembled cylinder 21 is extended downward and is tightly fitted into the mouth tube part 2 enhances the tight assembly of the coupling lid 20 to the mouth tube part 2.

  The continuous use container B (refer to FIG. 1 and FIG. 2 hereinafter) in the present invention has a bottle-shaped container body 30 and a body cap 40 that is tightly assembled to the mouthpiece 31 of the container body 30.

  The main body cap 40 (see FIG. 2) has a fitting cylinder 41 that fits tightly into the mouthpiece 31 of the container body 30 and a dispensing cylinder piece 44, and the dispensing cylinder piece 44 is a bottom plate 42 of the fitting cylinder 41. It is constructed in a straight cylindrical shape with a split groove provided in a part of the cylinder wall over the entire height range, and is connected to the upper end of the fitting cylinder 41 in the form of an outer casing, and the mounting cylinder 45 is erected. A mounting cylinder 46 is suspended from the outer peripheral end of the top plate.

  The bottom plate 42 has a tapered wall shape that is inclined downward to a position slightly deviated to one side, and a dispensing cylinder piece 44 is erected on the opening edge of the dispensing opening 43 established in the center portion thereof. The lower end opening 43a, which is the lowest part of the bottom plate 42 where the lower end of the opening side portion of the pouring cylinder piece 44 is located, functions as a liquid return port when the continuous use container B is used. It functions as an air outlet for the air inside the container body 30 during the refilling operation.

  Further, in the interior located slightly below the extraction cylinder piece 44, a push-up body 48 that pushes up and releases the inner plug 24 provided in the fitting cylinder 22 fitted and assembled to the extraction cylinder piece 44. The refill container A is opened in the inverted position and the inner plug 24 is opened and the refilling of the content liquid N is started simply by assembling and pushing down the refill container B.

  The mounting cylinder 45 is a part for screwing and assembling a measurement cap (not shown), and the mounting cylinder 46 is a part for undercut coupling the main body cap 40 to the mouth tube 31 of the container main body 30.

Next, the refilling operation of the content liquid N from the refill container A to the continuous use container B will be described.
The fitting cylinder 22 of the refill container A in the inverted posture is fitted and assembled (see FIG. 2) to the dispensing cylinder piece 44 of the main body cap 40 of the continuous use container B in the upright posture.

  Since the assembly posture of the refill container A with respect to the continuous use container B is achieved by being guided by the fitting of the fitting cylinder 22 into the dispensing cylinder piece 44, the fitting of the fitting cylinder 22 into the dispensing cylinder piece 44 proceeds. Accordingly, the assembly of the refill container A in the inverted posture with respect to the continuous use container B is stabilized.

  When the fitting cylinder 22 is fitted and assembled to the dispensing cylinder piece 44 and further pushed in, the pushing piece 49 of the push-up body 48 hits the inner plug 24, and a pushing force is applied to the inner plug 24. It becomes like this.

  When the fitting assembly of the fitting cylinder 22 with respect to the dispensing cylinder piece 44 further proceeds, first, the inner plug 24 is pushed upward by the action of the pushing-up force from the pushing-up portion 49a of the pushing-up piece 49, and is tilted and displaced. Then, the opening K starts to be formed by further pushing.

  When the assembly of the fitting cylinder 22 with respect to the extraction cylinder piece 44 is advanced, the open-tilted inner plug 24 is supported by a holding part 49b which is a part for holding the opening posture of the push-up piece 49, and the opening K is opened. The state (see FIG. 3) is maintained.

  When the opening K is formed, the content liquid N in the casing 1 of the refill container A naturally flows down by its own weight, and is poured into the container body 30 of the continuous use container B, and the refilling operation of the content liquid N is started. However, due to the natural dispensing of the content liquid N due to its own weight, decompression occurs in the housing 1.

  When decompression occurs in the housing 1, each panel wall 11 is deformed into a depressed shape with the ridge line 12 as a column part and the crease line 13 as a crease, and absorbs the decompression. Since the body 4 is inclined in the direction, the body 4 is deformed in a reduced volume by being reduced in the vertical direction (see FIG. 3) while being deformed by being twisted.

  The twist-like folding deformation in the body portion 4 is that three ridge lines 12 are formed at equal intervals, and the panel wall 11 is equally arranged in the circumferential direction with the same size and configuration. The depression deformation in each panel wall 11 proceeds in a substantially equal state, and the body portion 4 is reduced in volume by being reduced in the vertical direction without moving sideways.

  When the volume-reducing deformation reduced in the longitudinal direction of the body part 4 proceeds, the content liquid N is caused by the contact between the folded parts of the peripheral wall of the body part 4, the reduced pressure generated in the housing 1, the flow resistance at the opening K, and the like. The dispensing of the content liquid N is temporarily stopped due to the relationship between the force to pour out the liquid and the force to prevent the dispensing of the content liquid N.

  However, the stopping of the dispensing of the content liquid N is temporary, and the size of the opening K is set large enough to facilitate the natural dispensing of the content liquid N. Then, the outside air is sucked in the form of bubbles E (see FIG. 4), and the content liquid N is continuously poured out in the form of a breath to achieve refilling of the content liquid N.

  The body 4 of the casing 1 that has been refilled with the content liquid N is in a state of being folded and deformed vertically to some extent, but when the casing 1 is crushed in the vertical direction by hand, the casing 1 The body 4 of the body is sufficiently squeezed and stably squeezed so that the bottom 5 is embedded in the hemispherical shoulder 3 while being rotated and displaced with the folded peripheral wall folded. It can be disposed of while being self-maintained (see FIG. 5).

  Preferably, when the casing 1 is crushed, the bottom 5 may be rotated about 120 °. That is, the triangular shapes of the bottom 5 and the shoulder 3 match, whereby the crushed state of the housing 1 can be maintained, and the bottom 5 is embedded in the hemispherical shoulder 3. When fully crushed, the crushed state can be further stably maintained, and a good disposal state can be obtained.

  By setting the opening K large, the content liquid N can be poured out with breathing. FIG. 6 shows a configuration example in which the size of the opening K is set using the push-up body 48. In FIG. 6, the push-up body 48 includes a push-up piece 49 composed of a push-up portion 49a and a holding portion 49b, a beam piece 50 in which the push-up piece 49 is erected, and an assembly ring 51. Then, the assembly ring 51 is engaged with the engagement rib 47 provided on the inner peripheral surface of the extraction cylinder piece 44, thereby assembling the push-up body 48 to the extraction cylinder piece 44.

  In the embodiment of the push-up body 48 shown in FIG. 6, the push-up piece 49 is provided with a push-up portion 49a having a large height and a holding portion 49b having a low height separately. The pieces 49 are offset from the central position on the opposite sides, thereby tilting and opening the inner plug 24 in a certain direction, and holding the tilted and opened inner plug 24 in an open posture.

  The beam piece 50 in which the push-up piece 49 is erected is formed in a protruding piece shape extending to the position where the push-up piece 49 is erected, so that the flat piece along the line AA in FIG. As shown in FIG. 6B which is a cross section, an opening K as large as possible is formed.

  FIG. 7 shows a combination of the inner plug 24 with the hinge 25 and the push-up piece 49. In the case of the inner plug 24 with the hinge 25, its tilting and opening direction is constant and stable. A stable opening formation of the opening K by tilting opening of the plug 24 can be obtained.

  In the illustrated embodiment, the push-up body 48 is formed separately from the extraction cylinder piece 44. However, the push-up body 48 may be formed integrally with the extraction cylinder piece 44. Is possible.

  In addition, the adjustment of the relationship between the force to flow down the content liquid N and the force to prevent the content liquid N from being poured due to the decompression deformation of the housing is performed by adjusting the size of the opening K by the lifting body 48. It is not limited to adjustment, and the point is that any means can be used as long as it can adjust the passage area of the refill passage formed between the refill container A and the continuous use container B. Is possible.

  Further, the inner plug 24 is structured to be assembled to the fitting cylinder 22, but is not limited thereto, and may be integrally formed with the fitting cylinder 22.

  As described above, the combination of the continuous use container and the refill container in the present invention can easily and stably achieve sufficient volume reduction of the refill container after the refill, and has been refilled. As a waste disposal technology for refillable containers, a wide range of usage can be expected.
