Description

Refill container injection structure

The present invention relates to a refilling container pouring structure (spout) for refilling liquids such as liquid cosmetics or liquid detergents, liquid beverages, medicines, and the like into containers, and more specifically, The present invention relates to a refill container ejection structure that can be installed in a refill container and can be refilled easily and reliably without adding improvements to the container body.

In the past, although refilling detergents, shampoos, and hair creams was generally used to sell only contents, in recent years, only refilling cosmetics have been sold for expensive liquid cosmetics. Case. In addition, in the case of high-priced cosmetics, it is different from cheap shampoos or conditioners, and it is particularly strongly required that the contents can be reliably refilled without overflowing, so as not to cause much waste of the contents.

However, liquid cosmetics are usually sold in containers such as bottles. However, the mouth of such a container is intended to be used for ejection. In order to appropriately control the amount of the content, the caliber of the cosmetic is better. It is moderately small. Therefore, although the front end of the mouth of the container may be directly formed into a small diameter, on the other hand, if it is to be filled with the content Mouth, it is preferable to widen the diameter of the mouth as much as possible to avoid reducing the filling efficiency of the container. Therefore, a method of attaching an internal stopper having a small-diameter discharge port to the mouth portion of a discharge container has the advantage of satisfying both of them, and is therefore widely popular. Although the spit of the internal plug is determined by the viscosity of the liquid in the contents, the diameter is generally about 3mm to 12mm, and the makeup is lower in viscosity than shampoo or conditioner In the case of liquid cosmetics such as water and emulsion, the caliber is generally about 3 mm to 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 refilling liquid cosmetics, it is generally performed after the inner plug of the container is removed. However, the inner tether is excessively fitted to the mouth of the container so as not to be removed during normal use, and the unloading operation becomes complicated. In addition, there is a fear that the cosmetics remaining in the container due to errors may be spilled when the inner plug is removed.

In order to solve the above problems, Patent Documents 1 and 2 disclose a refilling container in which an inner plug is detachably attached to a mouth of the container. Although these containers are containers that remove the boredom caused by the removal of the inner plug as described above, the inner plug is formed into a cap shape, so there is a fear of covering the container from above. The outer lid becomes larger than the mouth of the container, and the design of the container may collapse. In addition, although the filling operation can be facilitated by removing the inner plug, there is a fear that the refilling container's injection port may fall off from the mouth of the container during refilling, or the contents may be spilled due to the container being overturned. In addition, liquid cosmetics such as lotions and lotions generally have a lower viscosity than about 6000 mPa˙s (25 ° C), and even when used with shampoos or shampoos, Pomades and the like are also relatively low in viscosity, so there is a fear that the contents may be spilled from the refill container during the period when the injection port of the refill container is directed downward and brought to the mouth of the container.

Therefore, in Patent Documents 3 and 4, in order to prevent the contents from being spilled during refilling, there is disclosed a refilling container having an inner cap (installation tube) attached to the mouth of the refilling container; An outer cap (operation member) that is slidably attached to the inner cap (installation tube) in the axial direction, and a seal portion that closes the injection port is provided in the inner cap (installation tube).

However, these containers are intended to be a container such as a shampoo or a dispenser of a conditioner that widens the mouth of the refilled container body during refilling, and is similar to cosmetics Container-like It is difficult to refill the container without using an internal plug for the purpose of using the container with an internal plug. In addition, these containers need to be restricted in their movements, etc., so as not to cause the seal portion to be broken due to the erroneous movement of the outer cap (operation member), and the structure thereof is also complicated.

Therefore, the problem of the present invention is to overcome the shortcomings of the conventional refilling container refilling mechanism, and to provide an injection structure for a refilling container for a general liquid container, including a cosmetic container. It can be widely used with or without it, especially for refilled containers equipped with an inner plug with a small-diameter outlet. It can be placed on the neck and neck of the refilled container while maintaining the inner plug installed. And easily refill the contents.

The present invention is to solve the above-mentioned problem, and is to cover the mouth and neck of the refilled container, and can be from the mouth of the refilled container, or from the inner plug installed on the mouth of the refilled container. The refill container ejection structure for refilling the contents at the ejection outlet is characterized in that it includes a cap, which is formed by a bottom and a peripheral wall erected from a peripheral edge of the bottom to form a neck for refilling the container. And a sliding member having a top wall and a peripheral wall hanging down from a peripheral edge of the top wall, and provided in the insertion portion so as to be slidable in an axial direction, and a bottom portion of the cap is formed by The injection port closed by the rupturable sealing portion is provided with an injection nozzle which can be inserted into the mouth portion of the refilled container or the outlet of the inner plug on the top wall of the sliding member. The lower surface is provided with a pressing portion protruding downward, and an injection flow path is formed therethrough from the injection nozzle to the pressing portion, and the sliding member is pressed into the cap to make The front end of the pressing portion abutting the sealing portion abuts against the sealing portion.

The injection structure for the refill container of the present invention does not cause the contents to spill even if the refill container is turned upside down, because the mouth portion of the refill container is inserted into the cap and the sealing portion is broken. Only the contents are ejected, so that the contents can be easily and reliably refilled.

In addition, the injection structure for a refilling container of the present invention is capable of making the injection nozzle by covering the container neck with a small-diameter cosmetic plug having an internal stopper and the like. Since it is inserted into the inner plug discharge port, the contents can be easily and reliably refilled without removing the inner plug from the refilled container.

In the figure, symbol 1 is a cap, 2 is a sliding member, 11 is a bottom, 12 is a peripheral wall, 13 is a cover portion, 14 is a lower peripheral wall, 15 is an opening, 16 is an injection port, 17 is a sealing portion, and 18 is a peripheral wall. 19 is the insertion part, 21 is the top wall, 22 is the peripheral wall, 23 For the injection nozzle, 24 is the pressing part, 25 is the injection flow path, 121 is the locking protrusion, 122 is the sliding part, 131 is the pressing part, 132 is the engaging part, 141 is the mounting part, and 171 is the easily broken part. 172 is a connecting portion, 211 is a convex portion, 221a is a locking groove, 221b is a locking groove, and 241 is a front end portion.

The injection structure for a refill container according to the present invention is composed of a cap 1 and a sliding member 2. The cap 1 is installed on the body of the refill container and covers the mouth and neck of the refill container. The slide The member 2 is slidably provided in the axial direction inside the cap 1. Each section will be described in detail below.

As shown in FIG. 1, the cap 1 has a bottom portion 11 and a peripheral wall 12 standing upright from the periphery of the bottom portion 11 to form an insertion portion 19 that can be inserted into the mouth and neck of a cosmetic container. A cover portion 13 is provided to close the opening 15 on the upper portion of the insertion portion 19 (the cover portion 13 is in an opened state in the first figure). In addition, a cylindrical lower peripheral wall 14 is provided on the back surface of the bottom portion 11 in a suspended state, and a mounting portion 141 is provided which can protrude in a lateral direction and can be mounted on the refill container body.

An injection port 16 is provided at the bottom portion 11 of the cap 1, and a peripheral wall 18 is erected in the insertion portion 19 so as to surround the peripheral edge portion of the injection port 16. Then, the injection port 16 is capable of closing its opening by the closing portion 17, and such a closing portion 17 is connected to the inside of the peripheral wall 18 by a breakable portion 171 formed by a wall thickness that can be broken by pressing. Around. Although such a frangible portion 171 may be provided on the entire periphery of the sealing portion 17, a connecting portion that is thicker than the frangible portion 171 and cannot be broken by pressing may be provided on a part of the peripheral edge of the sealing portion 17. 172. In addition, in this embodiment, although the sealing portion 17 is formed into a plate shape by using the same material as that of the other parts of the cap 1, as long as it can securely close the injection port 16 during storage, and refill it, In this case, the sealing portion 17 may be cracked and broken by pressing. For example, the sealing portion 17 may be formed of 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 easily-breakable portion on its peripheral edge.

A latching protrusion 121 is continuously projected in the circumferential direction below the inner peripheral surface of the peripheral wall 12 of the cap 1, and a plurality of anti-sliding portions 122 are protruded from the peripheral surface of the peripheral wall 12. Moreover, in this embodiment, although the cover part 13 which is openable and closable is integrally provided in the upper end of the peripheral wall 12, the cover part 13 may be a detachable member independently from the peripheral wall 12. An engaging portion 132 is provided perpendicularly from the back side of such a 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. Furthermore, a pressing portion 131 is convexly provided at the center of the back side of the cover portion 13.

As shown in FIG. 2, the sliding member 2 can be formed into a cover tube shape by the top wall 21 and the peripheral wall 22 hanging down from the peripheral edge of the top wall 21. Then, a pouring nozzle 23 protruding from above is provided from the top wall 21, and a pressing portion 24 protruding further downward than the lower end of the peripheral wall 22 is provided from the lower surface of the top wall 21. A discharge flow path 25 is formed in these discharge nozzles 23 and the pressing portion 24 so as to penetrate therethrough. Although the ejection nozzle 23 is formed with an outer diameter of the ejection opening 421 that can be inserted into an inner plug of a container such as a cosmetic, it is preferable that a slight gap is provided between the ejection nozzle 23 and the inner plug ejection outlet 421 to make the inside of the container The outer diameter of the air is set in such a way that it can escape during refilling. Further, a plurality of radiating ridge portions 211 are convexly provided on the upper surface of the top wall 21. Further, the outer peripheral surface of the peripheral wall 22 is provided with two upper and lower locking grooves 221a and 221b continuously in the circumferential direction. In addition, although the case where an internal stopper is installed in the refilled container has been described above, the injection structure for a refilled container of the present invention is a state in which the internal stopper is removed from the mouth of the container. The refilling operation can also be performed directly from the mouth. Further, for a container that does not have an internal stopper and has a small-diameter discharge outlet directly at the front end of the mouth of the container, the refill operation can also be performed from the discharge outlet. Even in these cases, it is preferable that a slight gap is provided between the mouth portion (spit) of the refilled container and the injection nozzle 23 to allow the air in the container to escape during refilling. Way to set its outer diameter.

In addition, in the above embodiment, although 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 to make the injection wider For example, as shown in FIG. 3 (a), the outlet channel 25 may form one or a plurality of longitudinal grooves 26 in an inner wall of the injection nozzle 23. Although the cross-sectional shape of the longitudinal groove 26 is a substantially semicircular shape in FIG. 3 (a), it is not limited to this, and may be an example of a polygonal cross-sectional shape having one or a plurality of apex angles. The shape shown in Fig. 3 (b). Also, although the longitudinal grooves 26 may be provided 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 injection of the contents.

FIG. 4 is a cross-sectional view showing a state before the slide member 2 is mounted in the cap 1 before refilling. In the insertion portion 19 of the cap 1, the sliding member 2 is installed with the injection 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 in the state where they are not locked to each other, in the axial direction (upward and downward directions in the drawing). ) Is formed with a sliding member 2 capable of sliding. FIG. 3 shows the locked state before use, and the locking projection 121 of the cap 1 is in a state of being 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 slide member 2 is in a state of being inserted into the peripheral wall 18 of the cap 1, and the front end portion 241 thereof is in a state of abutting on the sealing portion 17 in a ring shape. Specifically, the pressing portion 24 protrudes downward in a cylindrical shape, and the front end portion 241 of the pressing portion 24 is in contact with the easily broken portion 171 along the peripheral edge of the sealing portion 17. In addition, as in this embodiment, the peripheral wall of the pressing portion 24 becomes thinner as it comes to the front end, and becomes thinner at the front end portion 241, so that the pressing can be surely concentrated on the easily broken portion 171, so that it can be surely It is better to resist rupture. In addition, although the lid portion 13 is in a closed state, 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 ejection nozzle 23. Thereby, the sliding member 2 is pressed from above, and the sealing portion 17 abutted by the front end portion 241 of the pressing portion 24 is also pressed from above by the cover portion 13 indirectly. That is, although the sliding member 2 can be fixedly held on the cap 1 by the locking grooves 221a and the locking protrusions 121 as described above, the lid member 13 is also used to fix the sealing portion. 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 broken portion 171 can be prevented from being ejected toward the container according to the internal pressure of the container. The side of the flow path is broken. In the state where the lid portion 13 is closed, Next, since the sliding member 2 is in a state where it cannot be contacted from the outside, there is no risk that the sealing portion 17 may be broken by being pressed from above due to an error, and there is no need to restrict its movement.

Hereinafter, a method for refilling the contents using the injection structure for a refill container according to the present invention will be described by taking a cosmetic container in a state where an internal stopper is installed as an example. The refill container injection structure according to the present invention is attached to the mouth portion of the refill container 3. In addition, the refilled cosmetic container 4 is a type in which the contents are injected from the spout 421 of the inner plug 42. Since the liquid container has a lower viscosity as the content, the diameter of the inner plug spout 421 is formed. Smaller. The procedure for refilling such a cosmetic container 4 is as follows. First, the refill container 3 is turned upside down and held with the cap 1 turned downward, and the lid portion 13 is opened. In this state, since the sealed portion 17 is in a closed state, there is no risk that the contents of the refill container 3 will leak out. Next, as shown in FIG. 5 (a), the mouth and neck portion 41 of the refilled cosmetic container 4 is inserted into the insertion portion 19 of the cap 1 through the opening 15, and the inner plug 42 provided in the cosmetic container 4 is inserted. The inner plug discharge port 421 is inserted into the injection nozzle 23. In addition, unlike the present embodiment, in the case of refilling a cosmetic container in a state where 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 of a container having a small-diameter discharge port directly at the front end, the 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 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 coming into contact with the protruding portion 211 of the sliding member 2, the push-in operation is performed in order to further insert the mouth and neck portion 41 of the cosmetic container 4 into the insertion portion 19. As a result, although the upward force is applied to the sliding member 2 by the mouth and neck portion 41, when the upward pressing force becomes more than a certain value, the locking of the locking groove 221a and the locking protrusion 121 will be performed. The slide member 2 falls off, and the slide member 2 can slide further upward.

When the locking grooves 221a and the locking protrusions 121 fall off, only the contact between the pressing portion 24 and the sealing portion 17 will hinder the movement of the sliding member 2. Therefore, the pressing will be concentrated on the front end portion 241 of the pressing portion 24 and the seal. The contact portion of the part 17. Then, when the pressing becomes more than a certain amount, the sealing portion 17 leaves the contact portion 172 and starts to break from the frangible portion 171, and the injection port 16 is unsealed so that the front end portion 241 of the pressing portion 24 enters the injection port 16. At this time, since the connecting portion 172 is left and only the easily breakable portion 171 is broken, the sealing portion 17 is directly pressed 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 into the deepest portion in the insertion portion 19, the locking projection 121 of the cap 1 is locked to the locking groove 221 b of the sliding member 2. Thereby, the closing of the injection port 16 by the sealing portion 17 is opened and the content can be injected.

In the state of FIG. 5 (b), the contents are ejected from the opened injection port 16 through the injection channel 25 of the sliding member 2 to the refilled container (arrow A). At this time, although the contents can be smoothly injected by the escape of air from the refilled container, an outlet of the inner plug 42 is set around the injection nozzle 23 in order to create a gap for air leakage. The inner diameter of 421, and because the top wall 21 and the inner bolt 42 of the sliding member 2 prevent the close contact by the convex portion 211, a gap occurs, and the air in the container can escape from such a gap. Therefore, the refilling operation can be performed smoothly. In this way, since the refilling is performed with the injection nozzle 23 being inserted into the spout 421 of the inner plug 42, there is no need to remove the inner plug from the container body, and at the same time, the injection is not caused by an error during the refilling operation. The outlet may fall off the mouth of the cosmetic container and spill the contents.

Next, a second embodiment of the injection structure for a refill container according to the present invention will be described with reference to FIGS. 6 to 8. Since the basic structure is the same as the first aspect described above, the differences will be described below. First, as shown in FIG. 7, the sliding member 2 according to this embodiment has a front end portion 241 of the pressing portion 24 formed obliquely in a side view. In the figure, the front side projects further downward from the other portions. A protruding portion 241a is formed. In this embodiment, although the front side of the pressing portion 24 is in a protruding state, the protrusion is not limited to the front side, and the protruding portion 241a may be formed by protruding toward one of the left and right sides or the front end of the back side. Furthermore, in this embodiment, although the front end portion 241 of the pressing portion 24 is formed to be inclined substantially linearly, the front end portion 241 may be formed to be inclined in a curved manner, 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. In this way, by forming the protruding portion 241 a so that a part of the front end portion 241 of the pressing portion 24 protrudes more than other portions, the top of such a protruding portion 241 a can abut against the sealing portion 17. When refilling, In this part, the frangible portion 171 can be broken more reliably, and the sealing portion 17 can be unsealed.

In the front end portion 241 of the pressing portion 24, although the protruding portion 241a is provided at an arbitrary position, it is preferably provided at a position where the protruding portion 241a surely abuts the easily breakable portion 171 when performing a refilling operation. In addition, in order to prevent the relative positional relationship between the protruding portion 241a and the easily broken portion 171 from being shifted by rotating the sliding member 2 in the circumferential direction in the cap 1, it is preferable to provide a sliding member 2 described later. Means of preventing rotation.

On the inner peripheral surface of the peripheral wall 12 of the cap 1 according to this embodiment, a convex portion 123 is protruded so as to extend in a vertical direction as a means for preventing rotation of the sliding member 2. Although the position or the number of the convex strip portions 123 can be appropriately selected, it is preferable to provide at least two locations as in the embodiment.

In the sliding member 2 according to this embodiment, a recessed portion 222 extending in the vertical direction is recessed on the outer peripheral surface of the peripheral wall 22. Such a recessed portion 222 is provided at a position corresponding to the protruding portion 123 of the cap 1, and the protruding portion 123 is insertably formed. In this way, by inserting the protruding portion 123 into the recessed portion 222, it is possible to prevent the rotation in the circumferential direction in the cap 1 of the sliding member 2.

In addition, although the cover portion 13 of the cap 1 of this embodiment is provided at the upper end of the peripheral wall 12 on the side of the cap 1, the mounting position of the cover portion 13 is not limited to this, and it can also be as in the first embodiment It is generally provided on the back side of the cap 1.

Fig. 8 (a) shows a state where the sliding member 2 is inserted into the cap 1 according to the embodiment and the sealing portion 17 is not opened. As shown in the figure, since the front end portion 241 of the pressing portion 24 is formed obliquely, it is in a state where it comes into contact with the easily breakable portion 171 in the protruding portion 241 a protruding further downward than the other portions. Then, when the sliding member 2 is further pushed into the insertion portion 19 during the refilling operation, the pressing is concentrated on the contact portion between the protruding portion 241 a of the front end portion 241 and the easily broken portion 171. Therefore, the seal portion 17 will be opened from the contact portion between the easily-breakable portion 171 and the protruding portion 241a (FIG. 8 (b)).

The cap 1 and the sliding member 2 of the injection structure for the refilling container of the present invention can be formed of the same or different materials, respectively. For example, the cap 1 and the sliding member 2 can be formed of polypropylene or polyethylene. Polyolefin resin, polyethylene terephthalate, recycled polyethylene terephthalate, polyethylene naphthalate, polystyrene, propylene Acrylic nitrile-styrene copolymer, acrylic nitrile-butadiene-styrene copolymer, polycarbonate, polyamide (nylon ), Etc.), various synthetic resins such as polyacetal resin (POM) and acrylic resin. In addition, although the material of the refill container mounted on the cap 1 is not particularly limited, a pouch formed of a synthetic resin film such as polyethylene can also be smoothly passed from a thin injection port such as the injection nozzle 23 Bet out good.

In the present invention, the type of the liquid to be refilled in the container is not particularly limited. As long as it is liquid, it can be used in cosmetics or detergents, skin external preparations, beverages, food, pharmaceuticals, stationery, inks, stains, paints, etc. The effects of the present invention are utilized in various liquid products, and particularly in contents such as expensive cosmetics, skin external preparations, and medicines, the effects of the present invention can be particularly effectively enjoyed.
