Description

Injection filling structure for refilling container

The present invention relates to a refilling container dispensing structure (spout) for refilling a liquid cosmetic or liquid detergent, a liquid beverage, a drug, or the like into a container, and more particularly, A refill container dispensing structure that can be installed in a refill container without re-improving the container body and that is easy to refill the contents.

In the past, in general, in order to refill detergents, shampoos, and hair conditioners, only the contents are sold. However, in recent years, there has been an increase in the supply of refilling cosmetics for high-priced liquid cosmetics. Case. Moreover, in the case of high-priced cosmetics, it is different from inexpensive shampoos or hair conditioners, and it is particularly strongly required to reliably refill the contents without overflowing, so as not to cause waste of contents.

However, although the liquid cosmetic is usually placed in a container such as a bottle and sold, the mouth of such a container is preferably used for discharge, in order to appropriately control the discharge amount of the contents. It is moderately small. Therefore, although the front end of the mouth of the container is directly formed into a small diameter, on the other hand, if it is to be filled as a filling content. Preferably, the mouth is preferably widened as much as possible to avoid reducing the filling efficiency of the container. Therefore, the method of attaching the inner plug having the small-diameter discharge port to the mouth of the discharge container is advantageous in that it can satisfy both of them. Although the discharge opening of the inner plug is determined by the viscosity of the liquid of the contents, etc., it is generally about 3 mm to 12 mm, and the makeup is lower in viscosity than shampoo or moisturizer. In the case of a liquid cosmetic such as water or an emulsion, the diameter thereof is generally from about 3 mm to about 8 mm and tends to be smaller. Therefore, it is difficult to perform the refilling operation from the discharge port without removing the inner plug from the container body.

Therefore, in the case of performing refilling of the liquid cosmetic, it is generally carried out after the inner plug of the container is removed. However, the inner plug is excessively fitted to the container opening in order not to be removed during normal use, which makes the unloading operation complicated. Further, there is a fear that the cosmetics remaining in the container due to an error may be removed 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 plug is detachably attached to a mouth of a container. These containers are containers for eliminating the annoyance caused by the unloading of the inner plug as described above, but since the inner plug is formed into a cap shape, it is feared that it is capped from above. The outer cover becomes larger relative to the mouth of the container and the design of the container balances collapse. Further, although the injection operation can be easily performed by removing the inner plug, there is a fear that the injection port of the refill container may fall off from the mouth of the container during refilling, or the container may be inverted or the contents may be sprinkled. Furthermore, liquid cosmetics such as lotions or lotions are generally lower in viscosity than 6000 mPa ̇s (25 ° C), and even with shampoo or Since the hair conditioner and the like are relatively low in viscosity, the contents may be spilled from the refill container during the period in which the discharge port of the refill container is brought downward and brought to the mouth of the container.

Therefore, in Patent Documents 3 and 4, in order to prevent the sprinkling of the contents at the time of refilling, there is disclosed a refill container having an inner cap (installation cylinder) attached to the mouth of the refill container; And an outer cap (operation member) that is slidably attached to the inner cap (installation cylinder) in the axial direction, and such an inner cap (installation cylinder) is provided with a sealing portion that closes the injection port.

However, such containers are intended to be used as a container for refilling the mouth of the refilled end container body with a wide opening as in the case of a shampoo or a lotion dispenser, and such as cosmetics. It is difficult to refill the container for the use of the container with the inner plug without imagining and without removing the inner plug. Further, such containers are required to restrict the movement of the member or the like so as not to cause the outer cap (operating member) to move due to an erroneous movement to break the sealing portion, and the structure thereof is also complicated.

Hereinafter, an embodiment of the injection structure for a refill container of the present invention will be specifically described based on the drawings. Further, the present invention is not limited to such embodiments.

Fig. 1(a) is a front view of a cap portion of a dispensing structure for a refill container according to the present invention, (b) is a plan view, (c) is a central longitudinal sectional view; and Fig. 2(a) is a further embodiment of the present invention. A front view of the sliding member for the filling structure of the filling container, (b) is a plan view, and (c) is a cross-sectional view. In the figure, reference numeral 1 is a cap, 2 is a sliding member, 11 is a bottom, 12 is a peripheral wall, 13 is a lid portion, 14 is a lower peripheral wall, 15 is an opening, 16 is a spout, 17 is a sealing portion, and 18 is a peripheral wall. 19 is the insertion portion, 21 is the top wall, 22 is the peripheral wall, 23 In order to discharge the nozzle, 24 is a pressing portion, 25 is a discharge flow path, 121 is a locking projection, 122 is a sliding portion, 131 is a pressing portion, 132 is an engaging portion, 141 is a mounting portion, and 171 is a breakable portion. 172 is a connecting portion, 211 is a ridge portion, 221a is a locking groove, 221b is a locking groove, and 241 is a front end portion.

The dispensing structure for a refill container of the present invention comprises a cap 1 and a sliding member 2, the cap 1 being attached to the refill container body and covering the neck portion of the refill container, the sliding The member 2 is slidably disposed in the axial direction inside the cap 1. Hereinafter, each part will be described in detail.

As shown in Fig. 1, the cap 1 is formed by the bottom portion 11 and the peripheral wall 12 which is erected from the periphery of the bottom portion 11, to form an insertion portion 19 into which the neck portion of the cosmetic container can be inserted, and to open and close the upper end of the peripheral wall 12 freely. A lid portion 13 (closed state in which the lid portion 13 is opened in Fig. 1) for closing the upper opening 15 of the insertion portion 19 is provided. Further, on the back surface of the bottom portion 11, a cylindrical lower peripheral wall 14 is provided in a suspended state, and a mounting portion 141 for attaching the refillable container body that protrudes in the lateral direction is provided.

The bottom portion 11 of the cap 1 is provided with a spout 16 at the center thereof, and the peripheral wall 18 is erected in the insertion portion 19 so as to surround the peripheral edge portion of the spout 16 . Then, the injection port 16 can close the opening by the closing portion 17, and the closing portion 17 is connected to the peripheral wall 18 by the easily breakable portion 171 formed by the wall thickness which can be broken by pressing. Weekly. Although such a easily breakable portion 171 may be provided on the entire circumference of the sealing portion 17, a portion which is thicker than the easily breakable portion 171 and which cannot be broken by pressing may be provided in a part of the periphery of the sealing portion 17. 172. Further, in the present embodiment, the sealing portion 17 is formed into a plate shape by the same material as the other portions of the cap 1, but the filling port 16 can be reliably closed during storage and refilled. The sealing portion 17 may be formed by breaking the film by pressing. For example, the sealing portion 17 may be formed by a film-like material or a sheet-like material that can be broken. In this case, since the seal portion itself can be broken, it is not necessary to separately provide a breakable portion at the periphery thereof.

A locking protrusion 121 is protruded from the lower surface of the inner peripheral surface of the peripheral wall 12 of the cap 1 continuously in the circumferential direction, and a plurality of anti-slip portions 122 are protruded from the outer peripheral surface of the peripheral wall 12. Further, in the present embodiment, the lid portion 13 that is openable and closable is integrally provided at the upper end of the peripheral wall 12. However, the lid portion 13 may be a member that is detachable from the peripheral wall 12 independently. An engaging portion 132 is provided from the back side of the cover portion 13 so as to be engageable with the inner peripheral surface of the peripheral wall 12 of the cap 1 when the lid portion 13 is closed. Further, a pressing portion 131 is convexly provided at the center of the back side of the lid portion 13.

As shown in Fig. 2, the sliding member 2 can be formed into a lid cylinder shape by the top wall 21 and the peripheral wall 22 depending from the peripheral edge of the top wall 21. Then, the top wall 21 is provided with a discharge nozzle 23 that protrudes from above, and a pressing portion 24 that protrudes downward from the lower end of the peripheral wall 22 is provided from the lower surface of the top wall 21. The discharge flow path 25 is formed in the injection nozzle 23 and the pressing portion 24 in this manner. Although the injection nozzle 23 forms an outer diameter of the discharge port 421 that can be inserted into the inner plug of the container such as a cosmetic, it is preferable to provide a small gap between the injection nozzle 23 and the inner plug discharge port 421 to make the inside of the container. The air is set to escape when it is refilled. Further, a plurality of radiating ridge portions 211 are convexly formed on the upper surface of the top wall 21. Further, the outer peripheral surface of the peripheral wall 22 is provided with the upper and lower locking grooves 221a and the locking grooves 221b in the circumferential direction. Further, in the above description, the case where the inner plug is attached to the refill container is described. However, the refilling mechanism for the refill container of the present invention is in a state in which the inner plug is removed from the mouth of the container. It is also possible to carry out the refilling operation directly from the mouth, and it is also possible to carry out the refilling operation from the discharge port by a container having a small diameter opening at the front end of the mouth of the container without the inner plug. Even in such a case, it is preferable to provide a slight gap between the mouth portion (discharge port) of the refill end container and the discharge nozzle 23 to allow the air in the container to escape when refilling. The way is to set its outer diameter.

Further, in the above-described embodiment, the shape of the inner wall of the injection nozzle 23, that is, the shape of the cross section of the injection flow path 25 is circular as shown in Fig. 2(b), but for the sake of widerness. The outflow path 25 may, for example, form one or a plurality of longitudinal grooves 26 in a part of the inner wall of the injection nozzle 23 as shown in Fig. 3(a). Although the cross-sectional shape of the longitudinal groove 26 is substantially semicircular in FIG. 3(a), it is not limited thereto, and may be a cross-sectional shape of a polygon having one or a plurality of apex angles, for example. The shape shown in Fig. 3(b). Further, although the longitudinal grooves 26 may be arranged in parallel with respect to the axis of the injection flow path 25, they may be provided in a spiral shape as long as they do not interfere with the ejection of the contents.

Fig. 4 is a cross-sectional view showing a state in which the sliding member 2 is attached to the inside of the cap 1 before refilling. In the insertion portion 19 of the cap 1, the slide member 2 is attached in a state where the discharge nozzle 23 is directed upward. As shown in the figure, the outer diameter of the peripheral wall 22 of the sliding member 2 is formed substantially the same as the inner diameter of the peripheral wall 12 of the cap 1, and is in the axial direction in a state where it is not locked to each other (the vertical direction in the drawing) A sliding member 2 capable of sliding is formed. The third figure is the locked state before use, and the locking projection 121 of the cap 1 is in a state of being locked to the locking groove 221a of the sliding member 2.

In the 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 being in contact with the sealing portion 17 in a ring shape. Specifically, the pressing portion 24 protrudes downward in a cylindrical shape, and the distal end portion 241 is in contact with the easily breakable portion 171 along the circumference of the sealing portion 17. Further, according to the present embodiment, the peripheral wall of the pressing portion 24 is formed thinner as it comes to the distal end, and is thinner at the distal end portion 241, whereby the pressing can concentrate on the easily breakable portion 171 and can be surely It is better to resist the breakage. In addition, the lid portion 13 is in a closed state, but the pressing portion 131 provided on the back surface of the lid portion 13 in this state is in a state of abutting against the front end of the dispensing nozzle 23. As a result, the sliding member 2 is pressed from above, and the sealing portion 17 that the front end portion 241 of the pressing portion 24 abuts is also in a state of being indirectly pressed by the lid portion 13 from above. In other words, although the sliding member 2 can be fixedly held by the locking of the locking groove 221a and the locking projection 121 as described above, the cover member 13 is additionally fixed by the cover portion 13, whereby the sealing portion is fixed. 17 can also be pressed from above, and when the user strongly holds the refill container (especially a pouch), the sealing portion 17 or the easily breakable portion 171 can be prevented from being directed toward the injection according to the internal pressure of the container. The side of the flow path 25 is broken. Also, in the state of closing the lid portion 13 Since the sliding member 2 is in a state in which it cannot be contacted from the outside, there is no problem that the sealing portion 17 is broken from the upper portion due to an error, and there is no need to restrict the movement of the sealing member.

Hereinafter, a method of refilling the contents using the injection structure for a refill container of the present invention will be described by taking a cosmetic container in a state in which the inner plug is attached. The injection structure for a refill container of the present invention is attached to the mouth of the refill container 3. Further, the cosmetic container 4 of the refilling end is a type in which the contents are discharged 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 formed. Smaller. The order of refilling such a cosmetic container 4 is as follows. First, the refill container 3 is inverted and held in a state where the cap 1 is turned downward, and the lid portion 13 is opened. In this state, since the sealing portion 17 is in the closed state, the contents of the refill container 3 are not leaked. Next, as shown in Fig. 5(a), the neck portion 41 of the refilled cosmetic container 4 is inserted into the insertion portion 19 of the cap 1 from the opening 15, and the inner plug 42 is provided to the cosmetic container 4. The inner plug discharge port 421 is inserted into the injection nozzle 23. Further, unlike the present embodiment, in the case of refilling the cosmetic container in a state in which the inner plug is removed, the injection nozzle 23 is inserted into the mouth of the container, and is refilled at the mouth of the container without the inner plug. In the case where the front end portion directly has a small-diameter discharge port, the discharge nozzle 23 is inserted into the discharge port.

Next, the neck portion 41 of the cosmetic container 4 is inserted into the insertion portion 19 until the ridge portion 211 of the sliding member 2 comes into contact with the top surface of the inner plug 42 of the cosmetic container 4. Then, the inner plug 42 After the contact with the ridge portion 211 of the slide member 2, the push-in operation is performed in order to further insert the neck portion 41 of the cosmetic container 4 into the insertion portion 19. As a result, the sliding member 2 is biased upward by the mouth-and-neck portion 41. However, when the pressing in the upward direction is constant or more, the locking groove 221a and the locking projection 121 are locked. It falls off, and the sliding member 2 can slide further upward.

When the locking groove 221a and the locking projection 121 are locked off, only the contact between the pressing portion 24 and the sealing portion 17 hinders the movement of the sliding member 2, so that the pressing is concentrated on the front end portion 241 of the pressing portion 24 and the sealing. The contact portion of the portion 17. Then, when the pressing is constant or more, the sealing portion 17 leaves the contact portion 172 and breaks from the easily breakable portion 171, and the injection port 16 is opened to allow the front end portion 241 of the pressing portion 24 to enter the injection port 16. At this time, since only the easily breakable portion 171 is broken by leaving the connecting portion 172, the sealing portion 17 is directly pushed into the cap 1 in a state of being connected by the connecting portion 172 as shown in Fig. 5(b). status. In addition, in a state where the sliding member 2 is inserted at the deepest position in the insertion portion 19, the locking projection 121 of the cap 1 is locked to the locking groove 221b of the sliding member 2. Thereby, the clogging of the spout 16 by the sealing portion 17 is opened and the contents can be ejected.

In the state of Fig. 5(b), the contents are ejected from the opened injection port 16 through the injection flow path 25 of the sliding member 2 to the container at the refill end (arrow A). At this time, the contents can be smoothly injected by the escape of the air in the container of the refilling end, but the discharge port of the inner plug 42 is set around the injection nozzle 23 in order to manufacture the air gap for air leakage. The inner diameter of the 421 is further increased by the rib portion 211 due to the rib portion 211 being blocked by the rib portion 211, and the air in the container can escape from such a space. Therefore, the refilling operation can be performed smoothly. In this way, since the injection nozzle 23 is refilled while being inserted into the discharge port 421 of the inner plug 42, it is not necessary to remove the inner plug from the container body, and the injection is not caused by an error in the refilling operation. The outlet is detached from the mouth of the cosmetic container and the contents are sprinkled.

Next, a second embodiment of the injection molding structure for a refill container according to the present invention will be described with reference to Figs. 6 to 8 . Since the basic configuration is the same as the first aspect described above, the following points will be described. First, as shown in Fig. 7, the sliding member 2 of the present embodiment has an end portion 241 in which the pressing portion 24 is formed obliquely as viewed from the side, and in the figure, the front side is protruded toward the other portion. A protruding portion 241a is formed. In the present embodiment, the front side of the pressing portion 24 is in a protruding state, but the protruding portion is not limited to the front side, and the protruding portion 241a may be formed to protrude toward one of the left and right side faces or the front end of the back side. Further, in the present embodiment, the front end portion 241 of the pressing portion 24 is formed to be substantially linearly inclined, but the front end portion 241 may be formed to be curved obliquely, and may also be formed by a wave shape or a mountain shape. The curve forms part or all of the front end portion 241, and the waveform or the top of the mountain shape is more prominent than the other portions. As described above, by forming the protruding portion 241a so that a part of the front end portion 241 of the pressing portion 24 protrudes more than the other portions, the top portion of the protruding portion 241a can abut against the sealing portion 17. Then, when refilling, due to press concentration In this portion, the easily breakable portion 171 can be more reliably broken, and the sealing portion 17 can be opened.

In the end portion 241 of the pressing portion 24, the protruding portion 241a is provided at an arbitrary position, but it is preferably provided at a position where the protruding portion 241a reliably abuts against the easily breakable portion 171 when the refilling operation is performed. Further, in order to prevent the positional relationship between the protruding portion 241a and the easily breakable portion 171 from being displaced by rotating the sliding member 2 in the circumferential direction in the cap 1, it is preferable to provide the sliding member 2 to be described later. Rotation prevention means.

In the inner circumferential surface of the peripheral wall 12 of the cap 1 of the present embodiment, the ridge portion 123 is protruded so as to extend in the vertical direction as the rotation preventing means of the sliding member 2. Although the position or the number of the ridge portions 123 can be appropriately selected, as in the embodiment, it is preferable to provide at least two places.

In the sliding member 2 of the present embodiment, a groove portion 222 extending in the vertical direction is recessed in the outer peripheral surface of the peripheral wall 22. Such a groove portion 222 is provided at a position corresponding to the ridge portion 123 of the cap 1, and the ridge portion 123 is insertably formed. Thus, by the insertion of the ridge portion 123 into the groove portion 222, the rotation in the circumferential direction of the cap 1 of the sliding member 2 can be prevented.

In addition, although the cover portion 13 of the cap 1 of the present embodiment is provided at the upper end of the peripheral wall 12 on the side surface of the cap 1, the mounting position of the cover portion 13 is not limited thereto, and may be as in the first embodiment. It is generally disposed on the back side of the cap 1.

Fig. 8(a) shows a state in which the sliding member 2 is inserted into the cap 1 of the present embodiment, and the sealing portion 17 is not opened. As shown in the figure, the front end portion 241 of the pressing portion 24 is formed to be inclined, and thus the protruding portion 241a that protrudes downward from the other portion is in contact with the easily breakable portion 171. Then, when the sliding member 2 is further pushed into the insertion portion 19 during the refilling operation, the pressing is concentrated on the abutting portion of the protruding portion 241a of the distal end portion 241 and the easily breakable portion 171. Therefore, the contact portion between the easily breakable portion 171 and the protruding portion 241a is broken, and the sealing portion 17 is opened (Fig. 8(b)).

The cap 1 and the sliding member 2 of the dispensing structure for refilling containers of the present invention may be formed of the same or different materials, for example, polypropylene or polyethylene. Polyolefin resin, polyethylene terephthalate, recycled polyethylene terephthalate, polyethylene naphthalate, polystyrene, propylene Acrylic nitrile-styrene copolymer, acrylonitrile-butadiene-styrene copolymer, polycarbonate, polyamide (nylon) ), etc.), various synthetic resins such as polyacetal resin (POM) and acrylic resin. Further, the material of the refill container attached to the cap 1 is not particularly limited, but the pouch formed of a synthetic resin film such as polyethylene can be smoothly passed from a fine injection port such as the injection nozzle 23. Placed out, so good.

In the present invention, the type of the liquid to be refilled in the container is not particularly limited, and as long as it is liquid, it can be used in cosmetics or detergents, external preparations for skin, beverages, foods, medicines, stationery, inks, dyes, paints, and the like. The effects of the present invention are utilized in various liquid products, and the effects of the present invention can be particularly effectively enjoyed in contents such as high-priced cosmetics, skin external preparations, and pharmaceuticals.
