Description

Refill container pouring structure

The present invention relates to a refill container pouring structure (spout) for refilling a liquid into a container, such as liquid cosmetics, liquid detergents, liquid foods and drinks, and medicines, and more specifically, without improving the container body. The present invention relates to a refill container pouring structure that can be easily and surely refilled by being attached to a refill container.

Conventionally, it is common practice to sell only the contents for refilling detergents, shampoos and rinses, but in recent years, only cosmetics for refilling expensive liquid cosmetics have been sold. Increasing cases. In the case of expensive cosmetics, unlike cheap shampoos and rinses, there is a particularly strong demand for reliable refilling without spilling the contents so that the contents are not wasted at all.

By the way, liquid cosmetics are usually sold in containers such as bottles. However, the mouth of such containers is moderately small in order to control the discharge amount of contents to an appropriate amount for discharge. Is preferred. For this reason, the tip of the mouth of the container may be directly molded into a small diameter, but on the other hand, the filling port for filling the contents should be as wide as possible so as not to reduce the filling efficiency of the container. Is preferred. Therefore, a method of attaching an inner stopper having a small-diameter discharge port to the container port for discharge has been widely performed because it has the merit of satisfying both. The diameter of the outlet of this inner plug is determined by the viscosity of the liquid in the contents, but is generally about 3 mm to 12 mm, which is lower than that of shampoos and rinses. In some cases, the diameter is generally about 3 mm to 8 mm and tends to be smaller. Therefore, it was difficult to refill from the discharge port without removing the inner plug from the container body.

Therefore, when refilling liquid cosmetics, it is common to remove the inner stopper of the container. However, the inner plug is forcibly fitted to the container mouth so that it cannot be removed in normal use, and the removal work is complicated. In addition, there is a possibility that cosmetics remaining in the container may be accidentally spilled when the inner plug is removed.

In order to solve the above problems,

Patent Documents

1 and 2 disclose a refill container in which an inner stopper is removably attached to the mouth of the container. Although these things eliminate the troublesomeness associated with the removal of the inner plug as described above, since the inner plug is formed in a cap shape, the outer lid to be crowned from above is the container mouth portion. The design balance of the container may be lost. In addition, although the injection work is facilitated by removing the inner plug, the contents may spill out, for example, the spout of the refill container may come off the container mouth during refilling or the container may be overturned. there were. In addition, liquid cosmetics such as lotions and emulsions generally have a viscosity lower than about 6,000 mPa · s (25 ° C.), and are less viscous than shampoos and rinses. There was also a risk that the contents would spill out of the refill container before it was brought down to the container mouth.

Therefore, in

Patent Documents

3 and 4, in order to prevent spilling of contents during refilling, an inner cap (mounting cylinder) attached to the mouth of the refilling container and a container shaft with respect to the inner cap (mounting cylinder) are disclosed. There is disclosed a refill container including an outer cap (operation member) attached to be slidable in a direction, and the inner cap (mounting cylinder) provided with a seal portion for closing the spout.

However, these are intended for containers with a wide opening at the mouth of the container body at the time of refilling, such as shampoo and rinse dispenser containers. The use of was not envisaged, and it was difficult to refill without removing the inner plug. Furthermore, these containers have a complicated structure such that a member that restricts the movement of the container so that the outer cap (operation member) does not move accidentally and breaks the seal portion is necessary.

The refill container pouring structure of the present invention is attached to the main body of the refill container, and is provided with a cap 1 to be crowned on the mouth and neck of the container to be refilled and slidable in the axial direction inside the cap 1. It consists of a sliding member 2. Hereinafter, each part is explained in full detail.

As shown in FIG. 1, the cap 1 has an insertion portion 19 into which the mouth and neck of a cosmetic container can be inserted by a bottom portion 11 and a peripheral wall 12 standing from the periphery of the bottom portion 11. A lid portion 13 for sealing the upper opening 15 of the insertion portion 19 is provided so as to be openable and closable (the lid portion 13 is open in FIG. 1). In addition, a cylindrical lower peripheral wall 14 hangs down on the back surface of the bottom portion 11, and an attachment portion 141 to which the refill container main body is attached is provided so as to protrude in the lateral direction.

A spout 16 is provided in the center of the bottom 11 of the cap 1, and a peripheral wall 18 stands up in the insertion portion 19 so as to surround the peripheral edge of the spout 16. The opening of the spout 16 is closed by a seal portion 17, and the seal portion 17 is connected to the inner peripheral surface of the peripheral wall 18 by an easily breakable portion 171 formed to a thickness that can be broken by pressing. . The easily breakable portion 171 may be provided on the entire periphery of the seal portion 17, but a connection portion 172 that is thicker than the easily breakable portion 171 and is not broken by pressing may be provided on a part of the periphery of the seal portion 17. . In this embodiment, the seal portion 17 is formed in a plate shape with the same material as the other portions of the cap 1. However, the spout 16 can be reliably closed during storage, and can be broken by pressing during refilling. What is necessary is just what can be opened, for example, you may form the seal | sticker part 17 with the film-form raw material and sheet-like raw material which can be fractured | ruptured. In that case, since the seal part itself can be ruptured, it is not necessary to separately provide an easily breakable part at the periphery thereof.

A locking projection 121 is continuously provided in the circumferential direction at the lower part of the inner peripheral surface of the peripheral wall 12 of the cap 1, and a plurality of anti-slip portions 122 are provided at the outer peripheral surface of the peripheral wall 12. In the present embodiment, the lid 13 that can be opened and closed is integrally provided at the upper end of the peripheral wall 12, but the lid 13 may be a detachable member independent of the peripheral wall 12. An engaging portion 132 is suspended from the back side of the lid portion 13 and can be engaged with the inner peripheral surface of the peripheral wall 12 of the cap 1 when the lid portion 13 is closed. In addition, a pressing portion 131 projects from the center of the back side of the lid portion 13.

As shown in FIG. 2, the sliding member 2 is formed in a covered cylinder shape by a ceiling wall 21 and a peripheral wall 22 depending from the peripheral edge of the ceiling wall 21. A pouring nozzle 23 is provided so as to protrude upward from the upper surface of the top wall 21, and a pressing portion 24 is provided so as to protrude downward from the lower end of the peripheral wall 22 from the lower surface of the top wall 21. A pouring passage 25 is formed through the pouring nozzle 23 and the pressing portion 24. The dispensing nozzle 23 is formed to have an outer diameter that can be inserted into the discharge port 421 of the inner stopper of the container such as a cosmetic. However, a slight gap is provided between the outlet nozzle 23 and the inner stopper discharge port 421 to perform refilling. It is sometimes preferable to set the outer diameter so that air in the container escapes. A plurality of ridges 211 are radially provided on the top surface of the top wall 21. Furthermore, the outer peripheral surface of the peripheral wall 22 is provided with two locking grooves 221a and two locking grooves 221b in the circumferential direction. In the above description, the case where the inner plug is attached to the refilling container has been described. However, the refill container pouring structure according to the present invention is directly from the mouth even when the inner plug is removed from the mouth of the container. Further, a container having a small-diameter discharge port directly at the tip of the mouth of the container without having an inner stopper can be refilled from the discharge port. Even in these cases, it is preferable to provide a slight gap between the mouth portion (discharge port) of the refill destination container and the dispensing nozzle 23 and to set the outer diameter so that air in the container escapes during refilling.

In the above embodiment, the shape of the inner wall of the pouring nozzle 23, that is, the shape of the cross section of the pouring passage 25 is circular as shown in FIG. 2 (b), but in order to make the pouring passage 25 wider. For example, as shown in FIG. 3A, one or a plurality of vertical grooves 26 may be formed in a part of the inner wall of the dispensing nozzle 23. The cross-sectional shape of the longitudinal groove 26 is substantially semicircular in FIG. 3A, but is not limited to this, and is a polygonal cross-sectional shape having one or more apex angles, for example, FIG. 3B. The shape may be as follows. The longitudinal groove 26 may be provided in parallel to the axis of the extraction channel 25, but may be provided in a spiral shape within a range that does not hinder the extraction of the contents.

FIG. 4 is a cross-sectional view showing a state before refilling in which the sliding member 2 is attached in the cap 1. In the insertion portion 19 of the cap 1, the sliding member 2 is mounted with the dispensing nozzle 23 facing upward. As shown in the figure, the outer diameter of the peripheral wall 22 of the sliding member 2 is formed to be substantially the same as the inner diameter of the peripheral wall 12 of the cap 1, and the axial direction (vertical direction in the drawing) when not locked to each other. The sliding member 2 is formed to be slidable. FIG. 3 shows a locked state before use, in which the locking projection 121 of the cap 1 is locked in the locking groove 221 a of the sliding member 2.

In such a locked state, the lower portion of the pressing portion 24 of the sliding member 2 is inserted into the peripheral wall 18 of the cap 1, and the distal end portion 241 is in a state of annularly contacting the seal portion 17. ing. Specifically, the pressing portion 24 protrudes downward in a cylindrical shape, and the tip portion 241 is in contact with the easily breakable portion 171 on the periphery of the seal portion 17. Note that, as in this embodiment, the peripheral wall of the pressing portion 24 is formed thinner as it goes to the tip, and by making the tip portion 241 the thinnest, the pressure concentrates on the easily breakable portion 171 to ensure It is preferable because it can be broken. Further, the lid portion 13 is in a closed state, but in this state, the pressing portion 131 provided on the back surface of the lid portion 13 is in contact with the tip of the dispensing nozzle 23. As a result, the sliding member 2 is suppressed from above, and the seal portion 17 with which the tip portion 241 of the pressing portion 24 abuts is also indirectly suppressed from above by the lid portion 13. That is, the sliding member 2 is fixed and held with respect to the cap 1 by the locking of the locking groove 221a and the locking projection 121 as described above. The portion 17 is also suppressed from above, and when the user grips the refill container (especially a pouch) strongly, it is possible to prevent the seal portion 17 and the easily breakable portion 171 from breaking to the side of the dispensing path 25 due to an increase in the internal pressure of the container. . Further, when the lid 13 is closed, the sliding member 2 is in a state in which it cannot be contacted from the outside. Therefore, there is no possibility that the seal portion 17 is broken by being accidentally pushed from above, and a member that restricts the movement is also necessary. Absent.

Hereinafter, a method for refilling the contents using the refill container pouring structure according to the present invention will be described taking a cosmetic container with an inner plug as an example. The refill container pouring structure according to the present invention is attached to the mouth of the refill container 3. Further, the cosmetic container 4 to be refilled is of a type in which the contents are poured out from the discharge port 421 of the inner plug 42, and since the liquid cosmetic having a low viscosity is used as the content, the diameter of the inner plug discharge port 421 is reduced. Is formed smaller. The procedure for refilling the cosmetic container 4 is as follows. First, the refill container 3 is inverted and held with the cap 1 facing downward, and the lid 13 is opened. In this state, since the seal portion 17 is in a closed state, there is no possibility that the contents of the refill container 3 leak. Next, as shown in FIG. 5 (a), the mouth / neck portion 41 of the cosmetic container 4 to be refilled is inserted into the insertion portion 19 of the cap 1 through the opening 15, and provided in the inner plug 42 of the cosmetic container 4. The dispensing nozzle 23 is inserted into the inside plug outlet 421. In addition, unlike this embodiment, when refilling a cosmetic container with the inner plug removed, the small-diameter discharge port is directly attached to the container mouth, or directly to the front end of the container without the inner plug. In the case of refilling into a container having a discharge nozzle 23 is inserted into the discharge port.

Next, the mouth-and-neck portion 41 of the cosmetic container 4 is inserted into the insertion portion 19 until the convex strip 211 of the sliding member 2 comes into contact with the top surface of the inner stopper 42 of the cosmetic container 4. When the inner plug 42 and the protruding strip portion 211 of the sliding member 2 are in contact with each other, the mouth / neck portion 41 of the cosmetic container 4 is further pushed into the insertion portion 19 for insertion. As a result, an upward force is applied to the sliding member 2 by the mouth-and-neck portion 41. However, when the upward pressing exceeds a certain level, the locking groove 221a and the locking projection 121 are unlocked, and the sliding member 2 slides. The moving member 2 can slide further upward.

When the locking groove 221a and the locking projection 121 are unlocked, it is only the contact between the pressing portion 24 and the seal portion 17 that prevents the sliding member 2 from moving. The pressure concentrates on the contact portion of the seal portion 17. When the pressure exceeds a certain level, the periphery of the seal portion 17 is broken from the easily breakable portion 171 leaving the connection portion 172, the spout 16 is opened, and the tip 241 of the press portion 24 enters the spout 16. To do. At this time, since only the easily breakable portion 171 is broken while leaving the connecting portion 172, the seal portion 17 is pushed into the cap 1 while being connected by the connecting portion 172 as shown in FIG. In the state where the sliding member 2 is inserted deepest into the insertion portion 19, the locking projection 121 of the cap 1 is locked in the locking groove 221 b of the sliding member 2. Thereby, the obstruction | occlusion by the seal part 17 of the spout 16 is opened, and it will be in the state which can pour the content.

In the state of FIG. 5 (b), the contents are poured from the opened spout 16 into the refill destination container through the pouring path 25 of the sliding member 2 (arrow A). At this time, the contents are smoothly injected by the air in the refilling container being released, but the inner diameter of the discharge port 421 of the inner plug 42 is set so that a void for air venting is created around the pouring nozzle 23. Furthermore, since the close contact between the top wall 21 and the inner plug 42 of the sliding member 2 is hindered by the convex portion 211, a gap is generated, and air in the container can be released from the gap, so that the smoothness is smooth. Refill work can be performed. In this way, since refilling is performed in a state where the dispensing nozzle 23 is inserted into the discharge port 421 of the inner plug 42, there is no need to remove the inner plug from the container body, and the mouth of the cosmetic container during the refilling operation. There is no risk that the spout will be accidentally removed from the section and spilled.

Next, a second embodiment of the refill container pouring structure of the present invention will be described with reference to FIGS. Since the basic configuration is the same as that of the first aspect described above, differences will be described below. First, as shown in FIG. 7, in the sliding member 2 of this embodiment, the tip portion 241 of the pressing portion 24 is formed obliquely in a side view, and in this drawing, the front side protrudes downward with respect to other portions. Thus, the protruding portion 241a is formed. In the present embodiment, the front side of the pressing part 24 protrudes, but the protruding part is not limited to the front side, and the protruding part 241a may be formed to protrude from either the left or right side or the back side. . Further, in this embodiment, the tip portion 241 of the pressing portion 24 is formed so as to be inclined substantially linearly, but the tip portion 241 may be formed to be inclined in a curved line, A part or the whole may be constituted by a waveform or a peak-shaped curve, and the top of the waveform or the peak-shaped may protrude from the other part. In this way, by forming the protruding portion 241 a so that a part of the tip portion 241 of the pressing portion 24 protrudes from the other portion, the top portion of the protruding portion 241 a comes into contact with the seal portion 17. During the refilling operation, the pressure concentrates on the portion, so that the easily breakable portion 171 can be more reliably broken and the seal portion 17 can be opened.

The protruding portion 241a can be provided at an arbitrary position in the distal end portion 241 of the pressing portion 24. However, it is preferable to provide the protruding portion 241a at a position where the protruding portion 241a reliably contacts the easily breakable portion 171 during the refilling operation. In order to prevent the relative positional relationship between the projecting portion 241a and the easily breakable portion 171 from shifting due to the sliding member 2 rotating in the circumferential direction in the cap 1, the cap 1 and the sliding member 2 is preferably provided with means for preventing rotation of the sliding member 2 described later.

In the inner peripheral surface of the peripheral wall 12 of the cap 1 according to the present embodiment, as a means for preventing the rotation of the sliding member 2, a protruding portion 123 is provided so as to extend in the vertical direction. Although the position and number of the ridges 123 can be selected as appropriate, it is preferable to provide at least two as in the present embodiment.

In the sliding member 2 of the present embodiment, a concave groove 222 is provided in the outer peripheral surface of the peripheral wall 22 so as to extend in the vertical direction. The concave groove portion 222 is provided at a position corresponding to the convex strip portion 123 of the cap 1, and is formed so that the convex strip portion 123 can be inserted. As described above, by inserting the ridge 123 into the groove 222, it is possible to prevent the sliding member 2 from rotating in the circumferential direction within the cap 1.

In addition, although the cover part 13 of the cap 1 of this embodiment is provided in the upper end of the surrounding wall 12 of the cap 1 side surface, the attachment position of the cover part 13 is not limited to this, A cap like 1st embodiment 1 may be provided on the back side. *

FIG. 8A shows a state in which the sliding member 2 is inserted into the cap 1 of this embodiment and the seal portion 17 is not opened. As shown in the drawing, since the tip 241 of the pressing portion 24 is formed obliquely, the protruding portion 241a protruding downward from the other portion is in contact with the easily breakable portion 171. When the sliding member 2 is further pushed into the insertion portion 19 during the refilling operation, the pressure is concentrated on the contact portion between the protruding portion 241a of the distal end portion 241 and the easily breakable portion 171. Therefore, the rupture starts from the contact portion between the easily breakable portion 171 and the protruding portion 241a, and the seal portion 17 is in an opened state (FIG. 8b).

The cap 1 and the sliding member 2 of the refill container pouring structure according to the present invention can be formed of the same or different materials, for example, polyolefin resins such as polypropylene and polyethylene, polyethylene terephthalate, recycled polyethylene terephthalate, polyethylene It can be formed from various synthetic resins such as naphthalate, polystyrene, acrylonitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer, polycarbonate, polyamide resin (nylon, etc.), polyacetal resin (POM), acrylic resin, etc. . Moreover, there is no restriction | limiting in particular about the material of the refill container attached to the cap 1, However, Since the pouch formed with synthetic resin films, such as polyethylene, can be smoothly poured out from a thin pouring opening like the pouring nozzle 23, it is preferable.

In the present invention, the kind of liquid to be refilled in the container is not particularly limited, and various liquid products such as cosmetics, detergents, external preparations for skin, beverages, foods, medicines, stationery, inks, dyes, paints, etc., if liquid. The effects of the present invention can be utilized, but the effects of the present invention can be enjoyed particularly effectively when the contents are expensive, such as cosmetics, topical skin preparations, and medicines.
