Description

Refill method

The present invention relates to a refilling method for refilling liquid substances such as skin lotion and emulsion from a refilling container to the present container.

In order to save the resources and reduce the price of the product, it is necessary to pack the contents from the refill container into the container. It is being changed.

As the refill container, generally a thin bottle by pouch or blow molding is used. At the time of refilling, the contents are transferred to the main container by holding the refill container so that the outlet of the refill container is positioned above the mouth of the main container and gradually increasing the inclination of the refill container. .

However, when the refill container is a pouch, the refill container itself is not stretched and its outer shape changes as the contents are discharged, so that the contents discharged from the pouch do not come off the mouth of the container. Therefore, considerable care is required for gripping the pouch, which is complicated. There is also a problem that the spout is closed carelessly due to the overlap of the films constituting the pouch. The bottle is easier to hold the container when refilling than a pouch, but because the air replacement is not performed smoothly, the contents may be discharged in a pulsating manner, which causes the contents to foam unnecessarily Cause problems.

As a method for stabilizing the discharge of the contents from the refill container, it has been proposed to provide an air replacement path at the outlet of the refill container (Patent Document 1).

On the other hand, as an opening for forming the spout in the inner stopper sealing the mouth of the container body containing the liquid, the inner stopper is engraved with a cutting groove in the shape of the spout and surrounded by the cutting groove It is known that a pull ring is provided through a support in the removal part, and the cutting groove is cut by pulling up the pull ring, and the removal part is removed together with the pull ring so that the spout is opened (Patent Document 2). It is conceivable to provide such an opening in the refill container.

However, in the conventional opening portion using a pull ring, the pulling direction of the pull ring is difficult to be determined in one direction, and depending on the pulling direction, the cutting groove is not cut and the joining portion of the pull ring and the supporting portion of the supporting column or the removing portion of the supporting column is not provided. It breaks and the spout cannot be opened.

Hereinafter, the present invention will be described in detail with reference to the drawings. In each figure, the same numerals indicate the same or equivalent components.

FIG. 1A is a perspective view of a main container 10 and a refill container 40A according to an embodiment used in the refill method of the present invention. The main container 10 includes a main container body 11 for storing the liquid material A and a lid portion 20A.

This container body 11 has a bottomed cylindrical shape and is self-supporting, and has a mouth portion 12 upward. As shown in FIG. 1B (a), the peripheral wall of the mouth portion 12 is reduced in outer diameter in two steps toward the upper end portion, and a screw is formed on each of the thin peripheral wall upper portion 13 and the large diameter peripheral wall lower portion 14. Has been.

The lid portion 20A closes the mouth portion 12 of the container body 11 so as to be freely opened and closed, and more specifically includes an inner lid 21A and an outer lid 30 as shown in FIG. The inner lid 21 A has a substantially disk shape, has a small liquid discharge hole 22 at the center, and has an annular wall 23 around it. As shown in FIG. 2B, the inner side of the annular wall 23 of the inner lid 21A and the peripheral wall upper portion 13 of the mouth portion 12 of the main container body 11 are detachably screwed together. As shown in FIG. 2C, in the state where the inner lid 21A is screwed with the peripheral wall upper portion 13 of the mouth portion 12 of the container main body 11, the outer lid 30 is formed from the outer side of the inner lid 21A to the lower portion of the peripheral wall of the mouth portion 12. 14 and screw.

In general, the inner lid that has a small hole for discharging liquid that is attached to the container body containing the liquid material is fitted into the mouth of the container body by a driving method, so it cannot be easily attached and detached. Although it is difficult to refill the container body with the liquid material, according to this container 10, the inner lid 21 A is detachably attached to the mouth portion 12 of the container body 11 by screwing. When used as a liquid material discharge container, the inner lid 21A can be screwed into the mouth portion 12 of the main body 11 to discharge an appropriate amount of the liquid material A from the small liquid discharge hole 22, and the main body 11 can be discharged. When filling the liquid material A, it is easy to remove the inner lid 21A from the mouth portion 12 and fill the liquid material A from the mouth portion 12. Therefore, this container 10 is suitable for use in refilling the liquid material A.

On the other hand, as shown in FIG. 1A (b), the refill container 40A has a bottomed cylindrical refill container body 41 and the top of the refill container body 41 outward from the center axis L1 of the refill container body 41. A projecting portion 42 for projecting a dispensing nozzle is provided. The refill container main body 41 is formed from a thin blow-formed bottle, and is a self-supporting container that maintains a constant shape regardless of the presence or absence of contents.

The dispensing nozzle forming protrusion 42 stands up from a cap 43 formed integrally with the dispensing nozzle forming protrusion 42 and is fixed to the mouth of the refill container main body 41 by the cap 43 so as not to be detachable. Yes.

The dispensing nozzle forming protrusion 42 is such that the tip of the cylindrical body 44 is closed by an easy opening portion 45A, and the central axis L2 of the cylindrical body 44 is the central axis L1 of the refill container body 41. Matches. 1D, the outer diameter of the base portion 44a of the tubular body 44 is slightly smaller than the opening diameter of the mouth portion 12 of the container body 11, and the tubular body 44 is connected to the mouth portion 12 of the container body 11. In addition, it is a size that can be inserted almost without wobbling. Further, the outer diameter of the cap 43 is slightly larger than the opening diameter of the mouth portion 12 of the container main body 11, and the cylindrical body 44 is fixed to the main body 44 by a horizontal surface 44b of a step portion provided between the cap 43 and the base portion 44a. The cap 43 can be supported by the mouth 12 when inserted into the mouth 12 of the container body 11, that is, the refill container body 41 can be supported in an inverted state on the container body 11.

As shown in FIG. 4A, the easy-opening portion 45A includes an annular breakage portion 46 formed in the tubular body 44 so that an oblique spout opens at the distal end portion of the tubular body 44, and a tubular portion more than the annular breakage portion 46. It has a power point portion that is connected to the side surface of the cylindrical body on the distal end side of the cylindrical body 44. The force point portion is a portion where force is applied with fingers when the easy-open portion 45A is opened, and is formed as a ring-shaped finger hook portion 47 in this embodiment. Here, as the degree of inclination of the opening surface of the oblique outlet with respect to the cylindrical body 44, an angle θ (FIG. 4A (FIG. 4A ( b)) is preferably 30 to 60 °.

As a more specific form of formation of the annular fracture portion 46, for example, an annular groove is formed in the cylindrical body 44, and the cylindrical body 44 is made thin at this groove portion. As a result, as shown in FIG. 4B, when the finger hooking portion 47 is pulled up in the direction of the arrow with the upper end portion of the annular breaking portion 46 as a fulcrum, the annular breaking portion 46 breaks and the easy-opening portion 45A can be easily removed. . In addition, as the cyclic | annular fracture | rupture part 46, the thin part which made the wall thickness of the cylindrical body 44 thin from the front and back along the line which should be fracture | ruptured may be formed, and a half cut etc. may be formed. In addition, as long as the easy-opening portion 45A can be removed, the thin-walled portion, the half cut, and the like that form the annular fracture portion 46 can be formed continuously or intermittently.

When the easy-opening portion 45A is removed, the pouring nozzle forming protrusion 42 becomes the pouring nozzle 48 in a state where the opening surface of the tip is inclined with respect to the central axis L2 of the pouring nozzle and is obliquely cut.

In addition, the cap 43 provided with the protrusion portion 42 for forming the dispensing nozzle can be molded separately from the refill container main body 41. In addition, the filling of the liquid material A into the refill container 40A at the time of manufacture is performed before the cap 43 is attached to the mouth of the refill container body 41 and fixed.

In the refilling method of the present invention, as shown in FIG. 1B, first, the outer lid 30 and the inner lid 21A are removed from the main body 11 of the main container 10 to open the mouth portion 12. On the other hand, a finger is placed on the finger hooking portion 47 of the refilling container 40A and pulled up to remove the easy-opening portion 45A, whereby a refilling container 40A provided with a dispensing nozzle 48 is obtained. Then, as shown in FIG. 1C, the dispensing nozzle 48 of the refill container 40A is inserted into the mouth portion 12 of the main container body 11, and as shown in FIG. 1D, the refill container main body 41 is placed on the main container body 11. In this state, the main body 11 and the refill container body 41 are self-supported and the liquid material A is refilled.

At this time, the central axis L2 of the cylindrical body 44 and the central axis L1 of the refill container main body 41 coincide with each other, the refill container main body 41 stands vertically on the main container body 11, and the base 44a of the cylindrical body. The cylindrical body 44 is formed in such a size that the cylindrical body 44 does not fluctuate at the mouth part 12 of the container body 11, and the horizontal surface 44 b of the step part of the tubular body 44 is the upper edge of the mouth part 12 of the container body 11. Therefore, even if the refill container main body 41 is not gripped, the self-supporting state is maintained. Therefore, the trouble of gripping the refill container 40A can be greatly reduced so that the liquid material does not spill during refilling.

Moreover, since the pouring nozzle 48 has an appropriate diameter and the oblique pouring port 50 is formed at the tip, the pulsation of the liquid material A is suppressed, and the refilling container main body 41 smoothly moves to the main container body 11. Be poured out. Therefore, unnecessary foaming of the liquid A can also be suppressed. For example, when the viscosity of the liquid A is 500 mPa · s to 10000 mPa · s, the inner diameter of the discharge nozzle 48 is set to 12 to 20 mm, and the effect of suppressing the pulsation of the liquid A is This is particularly noticeable when the angle θ is 40 to 50 °.

The refilling method of the present invention can be applied to various main containers having an upward mouth. For example, the refilling method of the present invention can be suitably applied to the present container having the lid portion 20B shown in FIG. 3 instead of the lid portion 20A shown in FIG.

As shown in FIG. 3 (a), the lid portion 20B is a disc-shaped medium having an annular member 24 that is fitted into the mouth portion 12 of the container body 11 and a small hole 22 for discharging liquid at the center portion. It consists of a lid 21B and an outer lid 30. The annular member 24 and the inner lid 21 B are connected by a hinge 25. Therefore, the inner lid 21 B can cover the mouth portion 12 of the container body 11 so as to be freely opened and closed. As shown in FIG. 3C, the outer lid 30 is screwed into the mouth 12 of the main container body 11 from the outside of the inner lid 21 B with the inner lid 21 B covering the mouth 12 of the main container body 11. . Therefore, according to the container having the lid portion 20B, when used as a discharge container for the liquid A, the hinge 25 is closed and the opening of the container body 11 is closed by the inner lid 21B as shown in FIG. An appropriate amount of the liquid substance A can be discharged from the liquid discharge small hole 22 so as to cover the part 12, and when the main body 11 is filled with the liquid A, the hinge 25 is opened to open the mouth 12 of the main body 11. It is easy to fill the liquid A from the mouth portion 12. Therefore, this container having the lid portion 20B is also suitable for refilling the contents.

In addition, the lid member 20B may be formed by integrally forming the annular member 24, the inner lid 21B, and the hinge 25 connecting them, and the annular member 24 and the inner lid 21B molded separately are hinges 25. It may be connected with.

The refilling method of the present invention can be carried out using various refilling containers having a self-supporting property, having a dispensing nozzle having an oblique spout formed at the tip at the top of the refilling container body. Various refill containers provided with an easy-opening portion in which such a dispensing nozzle is formed can be used.

For example, in the refill container 40B shown in FIG. 5, the base portion 44a of the cylindrical body 44 that is cylindrical in the refill container 40A shown in FIG. 4A is formed into a rectangular tube shape with rounded corners on the side edges. Is. Thereby, as shown in FIG. 1D, even if the refill container 40A is inverted on the main body 11 and the liquid A is refilled so that the mouth 12 of the main body 11 is covered with the refill container 40A, Since the outer peripheral surface of the base portion 44a of the cylindrical body 44 is only in contact with the inner wall of the mouth portion 12 of the main body 11 of the container body 11 at its side edge portion, it does not touch the inner wall of the mouth portion 12 on the entire peripheral surface. Air can be vented. In addition, the refill container 40 A can be fixed to a certain extent on the main body 11 by bringing the side edge of the base 44 a of the cylindrical body 44 into contact with or close to the inner wall of the mouth 12 of the main body 11. The same effect can be obtained even if the cross-sectional shape of the base portion 44a of the cylindrical body 44 is an ellipse or a polygon with more corners.

Further, in the refill container 40A shown in FIG. 4A, the refill container main body 41, the extraction nozzle forming protrusion 42, and the cap 43 may be integrally formed. In that case, a separate opening is provided at the bottom of the refill container main body 41, the refill container main body is filled with the liquid material from the opening at the bottom, and after the filling, the bottom opening is sealed off by heat sealing or the like. That's fine.

In the refill container of the present invention, the cylindrical body 44 has an oblique spout opening at the tip of the cylindrical body 44, like the easy-open portion 45B of the refill container 40C shown in FIG. An annular break portion 46 may be formed, and a ring-shaped finger hook portion 47 may be erected as a power point portion on the end surface 49 on the distal end side of the cylindrical body surrounded by the annular break portion 46. In the refill container 40C, as shown by an arrow in FIG. 6B, the ring break portion 46 is broken by pulling the finger hook portion 47 upward, and the easy-open portion 45B is removed as shown by a broken line.

As in the refill container 40D shown in FIG. 7, the ring-shaped finger hook portion 47 serving as a power point portion in the easy-opening portion 45C is substantially horizontal on the cylindrical body distal end side end surface 49 surrounded by the annular fracture portion 46. The upper end portion of the cylindrical body distal end side end surface 49 and the finger hook portion 47 may be coupled so as to be supported by the upper end. In the refill container 40D, as shown by an arrow in FIG. 7B, by pulling the finger hook portion 47 obliquely downward, the annular fracture portion 46 is broken, and the easy-open portion 45C is removed as indicated by a broken line. The

As in the refill container 40E shown in FIG. 8, the ring surface of the ring-shaped finger hook portion 47 serving as a power point portion in the easy-opening portion 45D is placed on the side surface portion side of the cylindrical body 44 with the rising direction of the cylindrical body 44. Even if the upper end part of the removal part 51 and the upper end part of the finger hook part 47 which are provided so as to be parallel and are surrounded by the annular fracture part 46 on the end face 49 on the tip side of the cylindrical body are connected via the belt-like connection part 52. Good.

In this way, by extending the formation position of the finger hanging portion 47 not on the removal portion 51 but on the side surface side of the cylindrical body 44, an opening operation described later can be performed between the finger hanging portion 47 and the removal portion 51. A strong shearing stress can be applied to the annular fracture portion 46 in the vicinity of the connecting portion 52 so that the annular fracture portion 46 can be easily cut.

In this case, it is preferable that the lower end portion of the ring-shaped finger-hanging portion 47 and the upper surface of the cap 43 are connected with, for example, a twig-shaped connecting portion 54a so that the lower end portion can be easily separated by hand. As a result, it is possible to prevent the finger-hanging portion 47 from being bent around during the conveyance, etc., and being accidentally opened. Note that the position where the finger hook portion 47 is locked is not limited to the upper surface of the cap 43. For example, as shown in FIG. 8C, a locking portion 54b may be provided on the base 44a of the cylindrical body.

As a method for using the refill container 40E, as shown in FIG. 8B or FIG. 8C, first, the connecting portion 54a or 54b between the finger hooking portion 47 and the upper surface of the cap 43 is torn off, and the strip-shaped connecting portion 52 is used. The finger-hanging portion 47 is caused to be reversed as shown by a broken line (arrow a), and the finger-hanging portion 47 is further pulled down to the side opposite to the position where the original finger-hanging portion 47 is disposed (arrow b). Thereby, the cyclic | annular fracture | rupture part 46 fracture | ruptures and the easy-opening part 45D is removed as shown with a dashed-two dotted line. When the ring portion is reversed and caused in this way, a lever is applied to the upper end portion of the annular fracture portion 46 in the middle of the ring portion, so that a crack is generated, and the fracture spreads from there, so that opening is facilitated.

FIG. 9A is a perspective view of a refill container 40F provided with an easy-opening portion (hereinafter also referred to as an opening structure) 45E having a more preferable structure with respect to the above-described easy-opening portion 45D, and FIG. It is XX sectional drawing of the vicinity.

Also in this unsealing structure 45E, the distal end portion of the dispensing nozzle 48 is closed by a distal end surface 49 that is inclined with respect to the central axis L2 of the dispensing nozzle 48, and the distal end surface 49 is in contact with the distal end surface 49. An annular break portion 46 formed along the outer shape of the above, a removal portion 51 surrounded by the annular break portion 46, a short strip-shaped connecting portion 52 extending so as to stand up from the upper end portion of the removal portion 51, A finger hook portion 47 extending from the connecting portion 52 to the side surface of the dispensing nozzle 48 is provided, and the finger hook portion 47 is formed with a finger hook ring 47a. The connecting portion 52 does not stand up across the removing portion 51 and the outside thereof, and the joint surface between the connecting portion 52 and the removing portion 51 is located only inside the annular fracture portion 46.

Here, the inclination of the tip surface 49 is such that the angle θ between the central portion of the tip surface 49 and the central axis L2 of the dispensing nozzle 48 is 30 to 30 as shown in FIG. For example, when the inner diameter S1 of the dispensing nozzle 48 is 15 mm, the distance S2 between the upper end portion and the lower end portion of the annular fracture portion 46 is about 13.5 mm.

On the outer surface of the removal portion 51, the direction of pulling the finger rest portion 47 when the opening structure is opened is indicated by a thick portion 53 formed in an embossed shape in an arrow shape. Such an arrow-shaped thick portion 53 reinforces the joint area between the connecting portion 52 and the removing portion 51 so that the removing portion 51 can be turned evenly left and right by the pulling force when the opening is opened. Are suitably provided from the point of allowing the removal unit 51 to propagate well and the removal unit 51 to be easily removed and presenting the opening operation to the user in an easy-to-understand manner. As a specific example of the thickness and size of the thick portion 53, for example, in the above-described opening structure in which the inner diameter S1 of the pouring nozzle 48 is about 15 mm, the wall thickness S3 of the pouring nozzle 48 is 1.3 mm, and the removal portion 51 When the thickness S4 of the portion other than the thick portion 53 is set to 0.8 mm, the thickness S5 of the thick portion 53 is set to about 1.6 mm, and the horizontal length S6 of the thick portion 53 is set to about 7 mm. . The shape of the thick portion 53 is not limited to the illustrated arrow shape, and any shape may be used as long as the pulling force at the time of opening is transmitted to the removal portion 51 so that the removal portion 51 is turned up evenly on the left and right.

The finger hooking portion 47 serving as a pulling portion hangs down along the side surface of the pouring nozzle 48. Thus, in the state where the finger-hanging portion 47 is suspended, a specific example of the length S7 from the upper end to the lower end thereof is, for example, 20 mm.

In the present embodiment, one protruding portion 55 projecting toward the central portion of the removing portion 51 is provided at the removing portion side end portion 52 a of the short band-like connecting portion 52 that connects the removing portion 51 and the finger hanging portion 47. Is provided. As a result, the thickness D1 between the finger-hanging portion side surface 52a1 and the opposite side surface 52a2 at the removal portion-side end portion 52a of the connecting portion becomes the tension portion side surface 52b1 and the opposite side surface 52b2 at the finger-mounting portion 47 side end portion 52b of the connecting portion. The area of the cross section Sa of the removal part side end 52a of the connecting part 52 is larger than the area of the cross section Sb of the pulling part side end 52b. Is getting bigger. Here, the thickness D1 between the pulling portion side surface 52a1 and the opposite side surface 52a2 at the removal portion side end portion 52a of the connecting portion 52 refers to the maximum value of the distance between these surfaces 52a1, 52a2. It is not the thickness D1 ′ of the non-formed portion of 55 but equal to the maximum thickness of the convex portion 55. Similarly, the thickness D2 between the finger hook side surface 52b1 and the opposite side surface 52b2 at the finger hook portion 47 side end 52b of the connecting portion 52 is also the maximum value of the distance between these surfaces 52b1, 52b2. The length D2 is not affected even if a groove or the like is formed on these surfaces 52b1 and 52b2. As specific examples of the thicknesses D1 and D2, for example, in the above-described opening structure in which the inner diameter S1 of the pouring nozzle 48 is about 15 mm, D1 is preferably 1.5 to 7 mm, more preferably 3.5 to 5 mm, and D2 is preferable. Is 1.5 to 5 mm and 3 to 4 mm. Here, the cross-sectional area of the connecting portion 52 refers to the area of the surface perpendicular to the extending direction of the connecting portion 52 at the corresponding portion, and more specifically, the cross section Sa of the removal portion side end portion 52a described above. Is the area in the cross section Sa perpendicular to the extending direction of the removal portion side end 52a, and the area of the transverse section Sb of the pulling portion side end 52b is perpendicular to the extending direction of the pulling portion side end 52b. This refers to the area of the cross section Sb (FIG. 9B). During the opening operation, the thickness and the cross-sectional area of the connecting portion 52 change, but the thickness and the cross-sectional area here are the cross-sectional area when no external stress is applied. Various methods can be used for measuring the thickness and cross-sectional area regardless of contact type or non-contact type. For example, a measure such as a caliper or a laser displacement meter can be used.

The opening structure 45E opens the oblique outlet 50 by the following opening operation. First, the ring-shaped finger hanging portion 47 of the unsealing structure 45E is cut off from the top surface of the cap 43, and as shown in FIG. 10, the finger hanging ring 47a of the finger hanging portion 47 is lifted with a finger (arrow a). Are bent so as to be reversed and pulled up on the removal portion 51 (arrow b), and further, the finger hook portion 47 is substantially horizontal or obliquely downward along the removal portion 51 (arrow c) so as to move away from the initial position on the connecting portion 52 side. ), The annular fracture portion 46 is cleaved to remove the removal portion 51, and the oblique spout 50 is opened.

In this unsealing operation, as shown in FIG. 11A, when the finger hanging portion 47 is separated from the cap 43 and one end of the separation is lifted in the direction of arrow a, the ring surface of the finger hanging ring 47a of the finger hanging portion 47 becomes substantially horizontal. The connecting portion 52 starts to bend at a portion where the thickness of the connecting portion 52 just above the convex portion 55 is small.

When one end of the finger hook portion 47 is further lifted, the finger hook portion 47 is inverted as shown in FIG. 11B, and the ring surface of the finger hook ring 47a is brought closer to the removing portion 51 as shown by the arrow b, the convex portion 55 is bent. The connecting portion 52 is pushed in as shown by the arrow p. As shown in FIG. 11C, the finger hooking portion 47 is further inclined along the substantially horizontal or removal portion 51 (arrow c) so as to move away from the initial position of the connecting portion 52 along the tip surface 49 of the dispensing nozzle 48. When pulled to the connecting portion 52, the connecting portion 52 has an edge on the removing portion side end portion 52a on the removing portion center side, more specifically, by the lever action with the removing portion center side base portion 55a of the convex portion 55 as a fulcrum. A strong shearing stress acts on the annular fracture portion 46a in the vicinity of the removal portion side end 52a of the 52, and the annular fracture portion 46a is easily cut. After the annular broken portion 46a is cut, the remaining annular broken portion 46 can be easily cut off. Therefore, according to the opening structure 45E, the removal portion 51 can be easily removed and the oblique spout 50 can be opened by cutting the annular fracture portion 46. Further, according to this opening operation, the bending direction of the connecting portion 52 is stabilized in one direction, so that the pulling direction of the finger hooking portion 47 can also be regulated, and the belt-like connecting portion 52 is not twisted. Therefore, it is possible to prevent the finger rest portion 47 from being cut during the opening operation. In addition, since the finger-hanging portion 47 is provided at the tip of the pouring nozzle 48 protruding from the top surface of the cap 43, the peripheral wall around the pull ring is used as in the conventional opening structure described in Patent Document 1. The pulling operation of the finger rest portion 47 is not hindered.

In the present invention, regarding the shape of the connecting portion 52, as described above, instead of providing the convex portion 55 on a part of the strip-like connecting portion 52 on the removal portion 51 side, the easy-opening portion 45F in FIG. As shown in the figure, the removal portion side end portion 52 a of the band-like connecting portion 52 may be thicker and thicker as a whole than the finger hook portion side end portion 52 b of the connecting portion 52.

Further, as shown in the easy-opening portion 45G of FIG. 13, the cross-sectional area of the connecting portion 52 is formed in a circular or elliptical shape, and the removal portion side end portion 52a of the connecting portion 52 is the pulling portion side end portion of the connecting portion 52. The diameter may be gradually increased with respect to 52b.

As shown in the easy-opening portion 45H of FIG. 14, two or more convex portions 55 in the easy-opening portion 45E shown in FIG. 9A may be arranged side by side. In addition, when providing the convex part 55 which made thickness D1 of the removal part side edge part 52a thicker than thickness D2 of the finger hook part side edge part 52b of a connection part in the connection part 52, the connection part 52 is provided. The cross-sectional area of the removal portion side end portion 52a may not necessarily be larger than the cross-sectional area of the finger-hanging portion side end portion 52b of the connecting portion 52.

Also by these easy-opening portions (opening structures) 45F, 45G, and 45H, when the finger hook portion 47 is pulled as shown in FIGS. 11A to 11C, the removal portion side end portion 52a of the connection portion 52 is located on the center side of the removal portion. Due to the lever action with the base portion as a fulcrum, a strong shearing stress acts on the annular fracture portion 46a in the vicinity of the removal portion side end portion 52a of the connecting portion 52, so that the annular fracture portion 46a can be easily cut. In view of making the connecting portion 52 difficult to kink during the opening operation, the cross-sectional area of the connecting portion 52 is rectangular as shown in FIGS. 9A and 12 rather than the circular or elliptical shape shown in FIG. It is preferable to make 52 into strip shape. By sufficiently widening the width W (FIG. 9A) of the removal portion side end portion 52a of the connecting portion, the connecting portion 52 is less likely to be twisted, so that the pulling direction of the finger hanging portion 47 can be stabilized. The width W is preferably equal to or greater than the thickness.

Further, regarding the shape of the connecting portion 52, the cross-sectional area of the connecting portion 52 is made substantially constant from the removal portion side end portion 52a to the finger hanging portion side end portion 52b of the connecting portion 52 as in the easy opening portion 45I shown in FIG. Also good. In this case, as shown in FIG. 16A, the finger hanging portion 47 is pulled up on the removal portion 51 (arrow a), and the finger hanging portion 47 is moved along the tip end surface 49 of the dispensing nozzle as shown in FIG. In the opening operation of pulling away from the position (arrow b), the boundary portion between the connecting portion 52 and the removing portion 51 is bent, but the thickness and rigidity of the connecting portion 52 are determined so that the connecting portion 52 itself is not bent. Is preferred. Also with this easy-opening portion 45I, a strong shearing stress easily acts on the annular fracture portion 46a in the vicinity of the removal portion side end portion 52a of the connecting portion 52, and the annular fracture portion 46a can be easily cut.

The easy-opening part of the present invention may have an opening structure in which the connecting part 52 between the removing part 51 and the finger hooking part 47 is provided at the lower end part in the removing part 51 as in the easy-opening part 45J shown in FIG. . In this case, the finger hooking portion 47 is inverted on the removing portion 51 and then pulled obliquely upward.

For example, as in the refill container 40G shown in FIG. 18A, the easy-opening portion 45K is provided with an annular break portion 46 so that the tip end portion of the cylindrical body 44 is obliquely cut. You may provide the opening tab 60 extended from the enclosed cylindrical body front-end | tip part side end surface 49. As shown in FIG. According to this refill container 40G, as shown in FIG. 18B, by pulling up the opening tab 60, the easy-opening portion 45K rotates with the lowest point of the annular breaking portion 46 facing the opening tab 60 as a fulcrum. A force can be applied so as to move, and the easy-open portion 45K can be easily removed.

Further, as in the refill container 40H shown in FIG. 19A, as the easy-opening portion 45L, an annular break portion 46 is provided in the cylindrical body 44 so that an oblique spout is opened at the distal end portion of the cylindrical body 44. As an alternative, there may be provided a knob 61 formed of a semi-disc-shaped curved plate-like member standing on the end face side end surface 49 of the cylindrical body surrounded by the annular fracture portion 46. As shown in FIG. 19A (b), the cross section along the cylindrical body distal end side end surface 49 of the knob 61 is curved in an inverted S shape. Therefore, when removing the easy-opening portion 45L, a finger is applied to the curved portion of the knob portion 61, and as shown in FIG. 19B, the knob is made with the central axis L3 of the cylindrical body distal end side end surface 49 as the center of torsion. The part 61 can be twisted and the easy-opening part 45L can be removed.

A refill container 40I shown in FIG. 20A is obtained by forming a knob 61 from a corrugated plate member in the refill container 40H of FIG. 19A. As shown in FIG. 20B, the refill container 40I can also be twisted to remove the easy-opening portion 45M.

In addition, in the present container and the refill container of the present invention, the above-described deformation modes can be variously combined.

For example, the easy-opening part of the present invention is not limited to being formed on the dispensing nozzle protruding from the cap.
