Description

[Technical field]

[0001] The present invention relates to a discharge container with an overcap in which an overcap is attached to a discharge container body. [Background technology]

[0002] 2. Description of the Related Art Conventionally, as a container for containing a liquid content such as perfume or lotion, a dispensing container has been known which has a container body for containing the liquid content and a dispensing device such as a pump spray attached to the mouth of the container body by means of an attachment cap.

[0003] In order to prevent the discharge tool from accidentally activating when not in use, such discharge containers are generally configured as overcapped discharge containers by attaching an overcap to the mounting cap to cover the discharge tool (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2012-250148 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the above-mentioned conventional discharge container with an overcap, a convex portion is provided on the cylindrical outer peripheral surface of the attached cap, and this convex portion is undercut-engaged with an engagement groove provided on the inner peripheral surface of the peripheral wall of the overcap, extending circumferentially around the entire circumference, thereby allowing the overcap to be freely attached and detached while being held in place against the attached cap.

[0006] However, in the above-mentioned conventional dispensing container with an overcap, a gap is provided between the inner surface of the overcap and the outer surface of the attachment cap, so when the overcap is attached to the attachment cap, the overcap rattles against the attachment cap, resulting in a reduced feel when attaching and removing the overcap.

[0007] In response to this, it is conceivable to make the inner circumferential surface of the peripheral wall of the overcap smaller and fit the entire inner circumferential surface into the outer circumferential surface of the attachment cap. However, in this configuration, it is difficult to set the inner diameter of the peripheral wall of the overcap so that an appropriate frictional resistance occurs between the overcap and the attachment cap when attaching the overcap to the attachment cap, and the frictional resistance generated between the overcap and the attachment cap becomes too large, resulting in a poor operability when attaching and detaching the overcap.

[0008] The present invention was developed to solve such problems, and its purpose is to provide a dispensing container with an overcap that can improve the operability when attaching and removing the overcap. [Means for solving the problem]

[0009] The dispensing container with an overcap of the present invention is a dispensing container having a container body for containing the liquid contents, an attachment cap attached to the mouth of the container body, and a dispensing tool supported by the attachment cap, an overcap that is cylindrical with a top and has a top wall and a cylindrical peripheral wall and is removably attached to the attachment cap to cover the dispensing tool, a convex portion provided on the outer peripheral surface of the attachment cap, and an engagement groove that extends circumferentially around the entire inner peripheral surface of the peripheral wall and with which the convex portion engages, and is characterized in that a number of vertical ribs that abut the outer peripheral surface of the attachment cap are provided at intervals in the circumferential direction on the inner peripheral surface of the peripheral wall.

[0010] In the above-mentioned configuration of the discharge container with an overcap of the present invention, it is preferable that the peripheral wall has an annular groove that opens at the lower end of the peripheral wall and extends circumferentially around the entire circumference, and that the engagement groove is provided on the inner surface of the peripheral wall in the portion where the annular groove is provided.

[0011] In the above-mentioned configuration of the discharge container with an overcap of the present invention, it is preferable that the attachment cap has an outer wall including a cylindrical lower portion having a constant outer diameter and an upper portion having a tapered shape that is integrally connected above the lower portion and has an outer diameter that gradually decreases toward the top, and that the convex portion is provided on the outer peripheral surface of the lower portion and the multiple vertical ribs abut against the outer peripheral surface of the lower portion.

[0012] In the above-mentioned configuration of the overcap-equipped discharge container of the present invention, it is preferable that a plurality of the vertical ribs are provided at equal intervals in the circumferential direction on the inner peripheral surface of the peripheral wall. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, a detailed example of a dispensing container with an overcap 1 according to an embodiment of the present invention will be described with reference to the drawings.

[0016] In the claims and this specification, the up-down direction refers to the up-down direction when the overcap-equipped discharge container 1 is in an upright position as shown in FIG.

[0017] The dispensing container with an overcap 1 according to this embodiment can be used to store liquid such as perfume, lotion, etc. The dispensing container with an overcap 1 has a dispensing container body 10 and an overcap 20.

[0018] The discharge container body 10 has a container body 11 , an attachment cap 12 and a discharge tool 13 .

[0019] The container body 11 is in the shape of a bottle having a cylindrical mouth portion 11a and a cylindrical body portion 11b with a bottom, and can accommodate the liquid content in an accommodation space (not shown) provided inside the body portion 11b. In this embodiment, the container body 11 is a blow-molded container made of synthetic resin, but is not limited thereto, and may be one formed of other materials or by other manufacturing methods, such as a glass bottle. The shape of the container body 11 is also not particularly limited as long as it has the mouth portion 11a.

[0020] The attachment cap 12 is attached to the mouth 11a of the container body 11 and supports the discharge tool 13. In this embodiment, the attachment cap 12 is made of synthetic resin. The attachment cap 12 has a cylindrical attachment tube part 12a centered on the axis O of the mouth part 11a, and an outer peripheral wall 12b that is arranged coaxially outside the attachment tube part 12a and is integrally connected to the upper end of the attachment tube part 12a at the upper end, and is attached to the mouth part 11a by screwing the attachment tube part 12a to the mouth part 11a.

[0021] In addition, the attachment cap 12 is not limited to a configuration in which the attachment tubular portion 12a is attached to the mouth portion 11a of the container body 11 by screwing the attachment tubular portion 12a into the mouth portion 11a of the container body 11, but may be configured to be attached to the mouth portion 11a by attaching the attachment tubular portion 12a to the mouth portion 11a of the container body 11 by stoppering using an undercut engagement instead of screwing.

[0022] The outer peripheral wall 12b of the mounting cap 12 includes a lower portion 12b1 having a cylindrical shape centered on the axis O and having a constant outer diameter, and an upper portion 12b2 that is integrally connected to the upper portion of the lower portion 12b1 and has a tapered shape with an outer diameter that gradually decreases toward the upper portion. The upper portion 12b2 has a tapered shape with an outer peripheral surface that is smoothly curved so as to be convex toward the radially outward direction. In addition, an annular flange portion 12c that protrudes radially outward from the lower end of the lower portion 12b1 is integrally provided at the lower end of the lower portion 12b1. The provision of the flange portion 12c increases the rigidity of the lower end of the lower portion 12b1.

[0023] The mounting cap 12 may have any other shape as long as it has a cylindrical outer circumferential surface, such as a cylindrical shape having a constant outer diameter from the top end to the bottom end.

[0024] The mounting cap 12 may be configured such that the entire surface, including the outer peripheral surface of the outer peripheral wall 12b, is provided with a coating layer by vapor deposition.

[0025] A protrusion 14 is provided on the outer peripheral surface of the attachment cap 12. In this embodiment, three protrusions 14 are integrally provided at equal intervals in the circumferential direction on the outer peripheral surface of the lower end portion of the lower part 12b1 of the outer peripheral wall 12b of the attachment cap 12, as shown in Fig. 1 and Fig. 2 .

[0026] The number of protrusions 14 provided on the outer peripheral surface of the attachment cap 12 is not limited to three and can be changed in various ways. Also, the multiple protrusions 14 are preferably arranged at equal intervals in the circumferential direction on the outer peripheral surface of the attachment cap 12, but the arrangement can be changed in various ways.

[0027] The discharge tool 13 is for discharging the liquid content contained in the container body 11 to the outside. In this embodiment, the discharge tool 13 is a spray with a pump. More specifically, as shown in FIG. 1, the discharge tool 13 has a head 13a supported by the mounting cap 12 and protruding upward from the mounting cap 12, and a pump (not shown) connected to the head 13a via a stem 13b. The discharge tool 13 is configured such that when the head 13a is pressed down toward the inside of the mounting tube portion 12a, the pump (not shown) is activated to discharge the liquid content contained in the container body 11 to the outside in a spray form from a nozzle 13c provided on the head 13a.

[0028] In addition, the discharge device 13 is not limited to the above-mentioned pump-type spray, and various configurations such as an aerosol type discharge device can be used as long as it is capable of discharging the liquid contained in the container body 11 to the outside.

[0029] The overcap 20 is a cylindrical top having a top wall 21 and a cylindrical peripheral wall 22, and is detachably attached to the attachment cap 12 to cover the dispenser 13. In this embodiment, the overcap 20 is an injection-molded product made of synthetic resin.

[0030] 3, the top wall 21 is a circular plate curved to be slightly convex upward, and the peripheral wall 22 is cylindrical about the axis O and has an inner diameter slightly larger than the outer diameter of the lower portion 12b1 of the outer peripheral wall 12b of the attachment cap 12. The overcap 20 is attached to the attachment cap 12 by covering the attachment cap 12 and the dispenser 13 so that the peripheral wall 22 is positioned outside the outer peripheral wall 12b of the attachment cap 12.

[0031] As shown in Figs. 1 and 3, an inner peripheral surface 22a of the peripheral wall 22 of the overcap 20 is provided with an engagement groove 23 extending over the entire circumference in the circumferential direction. In this embodiment, the engagement groove 23 is provided on the inner peripheral surface 22a at the lower end side of the peripheral wall 22 in correspondence with the convex portion 14 of the attachment cap 12. As shown in Fig. 1, when the overcap 20 is attached to the attachment cap 12, the convex portion 14 provided on the outer peripheral surface of the attachment cap 12 is undercut-engaged with the engagement groove 23, so that the overcap 20 is held in a state attached to the attachment cap 12, i.e., in a state where it is prevented from coming off. When the overcap 20 is pulled upward from the state shown in Fig. 1 with respect to the discharge container body 10 as shown in Fig. 5, the undercut engagement of the convex portion 14 with the engagement groove 23 is released, and the overcap 20 can be removed from the attachment cap 12.

[0032] 1 and 3, in this embodiment, the peripheral wall 22 has an annular groove 22b that opens at the lower end of the peripheral wall 22 and extends around the entire circumference in the circumferential direction. By having the annular groove 22b, the lower end portion of the peripheral wall 22 is cylindrical and has a shape that branches into an inner peripheral wall portion 22c and an outer peripheral wall portion 22d that face each other in the radial direction centered on the axis O with the annular groove 22b therebetween. The engagement groove 23 is provided on the inner peripheral surface 22a of the inner peripheral wall portion 22c, which is the portion of the peripheral wall 22 where the annular groove 22b is provided.

[0033] The peripheral wall 22 may be configured without the annular groove 22b.

[0034] In this embodiment, when the overcap 20 is attached to the attachment cap 12 and the protrusion 14 provided on the outer circumferential surface of the attachment cap 12 is engaged with the engagement groove 23 by undercutting, the lower end of the inner peripheral wall portion 22c abuts against the flange portion 12c. This suppresses the rattling in the up-down direction of the overcap 20 attached to the attachment cap 12. In addition, the outer peripheral wall portion 22d extends downward more than the inner peripheral wall portion 22c, and when the overcap 20 is attached to the attachment cap 12, the flange portion 12c is covered from the outside by the outer peripheral wall portion 22d. This makes it difficult to see the flange portion 12c and the inner peripheral wall portion 22c abutting thereon from the outside when the overcap 20 is attached to the attachment cap 12, thereby improving the aesthetic appearance of the overcapped discharge container 1.

[0035] 1, 3, and 4, a plurality of vertical ribs 30 are provided at intervals in the circumferential direction on the inner peripheral surface 22a of the peripheral wall 22 of the overcap 20. In this embodiment, three vertical ribs 30 are provided integrally with the inner peripheral surface 22a of the peripheral wall 22 of the overcap 20, arranged at equal intervals in the circumferential direction.

[0036] The three vertical ribs 30 each extend straight downward from the upper end of the peripheral wall 22, i.e., the boundary with the top wall 21, in parallel with the axis O, with their lower ends positioned below the upper portion 12b2 of the peripheral wall 12b of the mounting cap 12 and above the flange portion 12c, and their lower end portions abut against the outer peripheral surface of the lower portion 12b1. In addition, the cross section perpendicular to the axis O of each of the three vertical ribs 30 is radial, and their lower ends are inclined such that the height of their projection from the outer peripheral surface of the lower portion 12b1 gradually decreases downward.

[0037] The number of the vertical ribs 30 provided on the inner peripheral surface 22a of the peripheral wall 22 of the overcap 20 is not limited to three and can be variously changed. The multiple vertical ribs 30 are preferably arranged at equal intervals in the circumferential direction on the inner peripheral surface 22a of the peripheral wall 22, but the arrangement can be variously changed. The cross-sectional shape of the multiple vertical ribs 30 perpendicular to the axis O is not limited to a semicircular shape and can be variously changed.

[0038] In the overcapped discharge container 1 according to the present embodiment having the above-mentioned configuration, the inner diameter of the inner peripheral surface 22a of the peripheral wall 22 of the overcap 20 is slightly larger than the outer diameter of the lower portion 12b1 of the outer peripheral wall 12b of the attachment cap 12, and the peripheral wall 22 is adapted to abut against the outer peripheral surface of the outer peripheral wall 12b of the attachment cap 12 at a plurality of vertical ribs 30 provided on the inner peripheral surface 22a. With this configuration, when the overcap 20 removed from the discharge container body 10 is attached to the attachment cap 12 as shown in FIG. 5, and when the overcap 20 attached to the attachment cap 12 is removed from the attachment cap 12 as shown in FIG. 1, it is possible to generate an appropriate frictional resistance without causing rattling between the overcap 20 and the attachment cap 12. Therefore, according to the overcapped discharge container 1 according to the present embodiment, it is possible to improve the operability when attaching and detaching the overcap 20 to and from the attachment cap 12.

[0039] Furthermore, in the overcap-equipped discharge container 1 of this embodiment, the peripheral wall 22 of the overcap 20 has an annular groove 22b that opens at the lower end of the peripheral wall 22 and extends around the entire circumference in the circumferential direction, and the engagement groove 23 is provided on the inner surface 22a of the peripheral wall 22 in the portion where the annular groove 22b is provided. Therefore, when the overcap 20 is attached to or detached from the attachment cap 12, when the convex portion 14 undercut engages with the engagement groove 23 or when the undercut engagement is released, the inner peripheral wall portion 22c can be appropriately elastically deformed radially outward so as to narrow the annular groove 22b, making it easy to attach and detach the overcap 20 to and from the attachment cap 12.

[0040] Furthermore, in the discharge container with overcap 1 according to this embodiment, the outer peripheral wall 12b of the attachment cap 12 is configured to include a cylindrical lower portion 12b1 having a constant outer diameter, and an upper portion 12b2 having a tapered shape that is integrally connected to the upper portion 12b1 and has an outer diameter that gradually decreases toward the top. The protrusion 14 provided on the outer peripheral surface of the attachment cap 12 is provided on the outer peripheral surface of the lower portion 12b1, and the multiple vertical ribs 30 are abutted against the outer peripheral surface of the lower portion 12b1. As a result, as shown in FIG. 5, when the overcap 20 removed from the discharge container body 10 is attached to the attachment cap 12, the multiple vertical ribs 30 are guided by the tapered upper portion 12b2 of the outer peripheral wall 12b of the attachment cap 12 and smoothly engage with the outer peripheral surface of the lower portion 12b1, thereby further improving the operability when attaching the overcap 20 to the attachment cap 12.

[0041] Furthermore, in the overcap-equipped discharge container 1 of this embodiment, multiple vertical ribs 30 are provided at equal intervals in the circumferential direction on the inner surface 22a of the peripheral wall 22 of the overcap 20. Therefore, when the overcap 20 is attached to or detached from the attachment cap 12, the multiple vertical ribs 30 guide the overcap 20 coaxially relative to the attachment cap 12, making it even easier to attach and detach the overcap 20 to or from the attachment cap 12.

[0042] Furthermore, by configuring the outer peripheral surface of the mounting cap 12 to be coated by vapor deposition, the frictional resistance of the multiple vertical ribs 30 against the outer peripheral surface of the mounting cap 12 can be reduced, making it even easier to attach and detach the overcap 20 to and from the mounting cap 12.

[0043] The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the spirit and scope of the present invention. [Explanation of symbols]
