Description

[Technical Field]

[0001] The present invention relates to a refill container, and more particularly to a refill container in which the main part of the refill container is formed from glass. [Background technology]

[0002] A refill container is known in which a shoulder cover is rotatably disposed on the upper end surface of a cylindrical wide-mouthed first container body (container body) with a bottom, and a second container body (refill container) engaged with the shoulder cover is fitted inside the first container body (Patent Document 1). This refill container is configured so that by rotating the shoulder cover, the second container body can be locked into the first container body or released from the locked state. Patent Document 1 also lists glass as an example of a material for forming the container body (paragraph 0015). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2016-11130 Summary of the Invention [Problem to be solved by the invention]

[0004] Generally, glass containers vary widely in size, limiting the methods of fitting and sealing them. When a glass container is used as a refill container, a typical installation method is to sandwich a part of the refill container between the shoulder part and the container body, as in Patent Document 1. However, this is disadvantageous in terms of design, since it is not possible to adopt various fitting methods depending on the weight, size, etc. of the refill container.

[0005] An object of the present invention is to provide a refill container whose main body is made of glass and to which various fitting methods can be applied. [Means for solving the problem]

[0006] The first means comprises a container body 2 having a neck portion 12, a refill container (20) comprising a glass, bottomed, cylindrical content-storing container (22) with a separate inner stopper (40) attached to the mouth (30) thereof, the content-storing container (22) being disposed within the container body (2) with the inner stopper (40) detachably fitted to the mouth-neck portion (12); A lid body 70 is detachably arranged on the upper side of this refill container 20, Equipped with The inside plug 40 has an inside plug body 42 threadedly attached to the mouth portion 30 and an engaging portion 54 extending downward from the inside plug body 42, and this engaging portion 54 is detachably fitted into the mouth neck portion 12.

[0007] 1(B), a separate inner plug 40 is attached to the mouth 30 of the glass content-storing container 22, and a fitting portion 54 extends downward from the inner plug body 42 of the inner plug 40, and this fitting portion 54 is fitted into the mouth-neck portion 12 of the container body 2. The inner plug 40 is then screwed into the mouth 30 of the content-storing container 22. According to this structure, the glass content storage container body 22 is fitted to the container body 2 via the inner stopper 40, so good fitting can be achieved regardless of variations in the dimensions of the glass part. Furthermore, by unscrewing the inner plug 40 from the opening 30 of the contents-storing container body 22, it can be easily separated from the contents-storing container body 22, making it easy to separate and dispose of.

[0008] The second means includes the first means, and a gap g is provided between the outer peripheral surface of the contents-storing container body 22 and the inner peripheral surface of the container main body 2.

[0009] In this means, as shown in FIG. 1(B), a gap g is provided between the outer peripheral surface of the contents-storing container body 22 and the inner peripheral surface of the container main body 2. According to this structure, when removing the contents storage container body 22 from the container main body 2, the frictional resistance between the surfaces of both can be reduced or eliminated, making it easy to refill the refill container 20.

[0010] The third means includes the first means or the second means, and the fitting portion 54 is suspended from the outer surface of the inside plug body 42 around the neck portion 12 via a connecting portion 52 that protrudes outward from the outer surface, and is screwed onto the outer surface of the neck portion 12.

[0011] In this method, as shown in Figure 1 (B), by screwing the fitting portion 54 onto the mouth and neck portion 12, the refill container 20 can be securely fitted into the container body 2 without being affected by molding errors in the glass portion of the refill container 20, resulting in good fitting properties.

[0012] The fourth means comprises any one of the first to third means, and the fitting portion (54) is suspended from the outer surface of the inside plug body (42) via a connecting portion (52) protruding outward from the outer surface so as to follow the inner circumferential surface of the mouth / neck portion (12), and is fitted into the inner circumferential surface of the mouth / neck portion (12); An engagement groove 60 is formed on one of the opposing surfaces of the fitting portion 54 and the mouth-neck portion 12, and a locking protrusion 16 that is detachably locked into the engagement groove 60 is formed on the other, thereby achieving an undercut fit between the fitting portion 54 and the mouth-neck portion 12.

[0013] In this means, as shown in Figure 4 (B), an engagement groove 60 is formed on one of the opposing surfaces of the fitting portion 54 and the mouth / neck portion 12, and an engagement protrusion 16 that engages within the engagement groove 60 is formed on the other. This structure allows for undercut fitting to the refill container 20, which is mainly made of glass. [Effects of the Invention]

[0014] According to the present invention, although the main body of the refill container is made of glass, various fitting methods can be applied. [Brief explanation of the drawings]

[Figure 5] This is an explanatory diagram of how to use the refill container shown in Figure 4, where (A) shows the stage of lifting the refill container from the container body after removing the lid, and (B) shows the shape of the new refill container before it is placed in the container body (the shape at the distribution stage). [Figure 6] This shows a refill container according to the third embodiment of the present invention, where (A) is a half cross-sectional view from the front, and (B) is an explanatory diagram of the stage in which the refill container is lifted up from the container body after the lid is removed. BEST MODE FOR CARRYING OUT THE INVENTION

[0016] 1 to 3 show a refill container according to an embodiment of the present invention. This refill container is made up of a container body 2, a refill container 20, and a lid .

[0017] The container body 2 is cylindrical with a bottom, and has a wide-mouthed neck portion 12 that stands up from the body portion (inner cylindrical wall 6b, described later, in the illustrated example). In this embodiment, the container body 2 is formed of an outer container body 2a and an inner container body 2b, although it may be formed of a single container body. The outer container body 2a and the inner container body 2b can be made of, for example, a synthetic resin material. The outer container body 2a has an outer tubular wall 6a extending from the peripheral edge of the outer bottom wall 4a. The inner container body 2b has an inner tubular wall 6b extending from the peripheral edge of the inner bottom wall 4b, and a neck portion 12 extends upward from the upper end of the inner tubular wall 6b. A first male thread 14 is formed on the outer surface of the neck portion 12. In the illustrated example, as shown in Fig. 1(B), the opening / neck portion 12 is formed into a small outer diameter portion that is reduced in diameter relative to the inner cylindrical wall 6b via a first step portion 8. However, this form can be modified as appropriate. In this embodiment, the inner container 2b is housed in the outer container 2a with a distance between the outer bottom wall 4a and the inner bottom wall 4b, although this structure can be modified as appropriate. A first flange portion b1 protrudes outward (horizontally outward) from the upper end of the inner cylindrical wall 6b, and engages with the upper end of the outer cylindrical wall 6a. The inner container body 2b is supported within the outer container body 2a via this first flange portion b1. In this embodiment, the first step portion 8 and the upper end of the outer tubular wall 6a are located at the same height. A pair of locking protrusions 10 are attached to the corner between the first step portion 8 and the lower end of the neck portion 12, spaced apart from each other in the circumferential direction, and are formed so that an engaging protrusion 58 (described later) can be fitted between these locking protrusions 10. Additionally, a first anti-rotation means d1 is formed below the first flange b1 to prevent the outer container 2a from rotating freely relative to the inner container 2b. In the illustrated example, this first anti-rotation means d1 is formed by fitting an engaging protrusion on the outer surface of the inner container 2b into a recess formed on the inner surface of the outer container 2a. However, this structure can be modified as needed.

[0018] As shown in Fig. 1(B), the refill container 20 is formed by a contents-storing container body 22 and an inside plug 40. In the figure, "c" denotes the contents. The inside plug 40 is a separate member from the contents-storing container body 22.

[0019] The content storage container body 22 is a wide-mouthed container made of glass. This content-storing container body 22 has a thick-walled circumferential wall 26 rising from the peripheral edge of the bottom 24, and a mouth 30, which has a smaller outer diameter than the circumferential wall 26, rising above the circumferential wall 26 via a second step 28 shown in Fig. 2. This mouth 30 is located higher than the mouth / neck portion 12, as shown in Fig. 1(B). The mouth portion 30 in the illustrated example is a vertically tubular mouth portion, and a fitting recess 34, which is a large inner diameter portion, is formed on the inner surface of the upper end portion thereof. A second male thread portion 32 is formed on the outer surface of the mouth portion 30 . A thick second flange b2 projects outward from the upper end of the outer surface of the body peripheral wall 26. The content-storing container body 22 in the illustrated example is supported in a suspended state inside the container body 2, with a gap v between it and the inner bottom wall portion 4b, with the inner stopper 40 removably fitted into the mouth and neck portion 12 as described below. Furthermore, an annular gap g is formed between the outer peripheral surface of the trunk circumferential wall 26 and the inner surface of the container body 2 (in the illustrated example, the inner surface of the inner cylindrical wall 6b), as viewed from above. This makes it possible to avoid or reduce friction between the trunk circumferential wall 26 and the container body 2 when replacing the refill container 20. It is desirable that the gap g be provided over the entire height of the inner cylindrical wall 6b.

[0020] As shown in FIG. 1(B), the inside plug 40 comprises an inside plug body 42, a flange-shaped connecting portion 52 extending outward from the inside plug body 42, and a fitting portion 54 connected to the connecting portion 52. The inside plug can be made of, for example, a synthetic resin material. Although the inside plug 40 in the illustrated example is molded as a single piece, its structure can be modified as appropriate.

[0021] The inner plug body 42 is a part that is assembled to the mouth portion 30, and in the illustrated example, as shown in Figure 2, it is configured so that the mouth portion 30 is sandwiched between an inner peripheral wall 46 and an outer peripheral wall 48 that hang down from an annular top plate portion 44. However, these structures can be modified as appropriate. The upper surface of the illustrated annular top plate portion 44 is formed as a horizontal, flat annular surface. The inner peripheral wall 46 is fitted into the fitting recess 34 of the mouth portion 30 . A second female screw portion 50 that meshes with the second male screw portion 32 is formed on the inner surface of the outer peripheral wall 48 . Further, a third male thread portion 51 is formed on the outer surface of the outer peripheral wall 48 . In the illustrated example, an annular sealing means o such as an O-ring is disposed between the upper end surface of the mouth portion 30 and the annular top plate portion 44. This allows the inside plug 40 to be threadedly fitted into the contents-storing container body 22 with the O-ring interposed between the mouth portion 30 and the annular top plate portion 44. However, these structures can be modified as appropriate.

[0022] The connecting portion 52 is a portion that connects the inside plug body 42 and the fitting portion 54, and is provided extending outward from a suitable position on the outer peripheral wall 48 (the lower end portion in the illustrated example). In this embodiment, the fitting portion 54 is provided vertically from the peripheral end of a flange-shaped connecting portion 52 that projects outward from the outer surface of the outer peripheral wall 48, but the structure can be modified as appropriate. In this specification, the term "flange-shaped connecting portion" includes not only the outward flange shown in the illustrated example, but also a connecting piece protruding outward from a circumferential portion of the outer peripheral wall.

[0023] The fitting portion 54 is a fitting means for fitting to the mouth / neck portion 12, and is disposed below the inside plug body (lower and outer in the illustrated example). In this embodiment, the fitting portion 54 is suspended from an appropriate position of the connecting portion 52 (in the illustrated example, the outer peripheral end portion) along the outer surface of the mouth-neck portion 12 and is fitted into the mouth-neck portion 12. The fitting portion in this embodiment is formed in a cylindrical portion (fitting cylindrical portion), but the structure thereof can be changed as appropriate as long as the required fitting force can be exerted. By fitting the fitting portion 54 of the inner stopper 40, which is separate from the content storage container body 22, which is a glass product, into the mouth and neck portion 12, it can be fitted into the mouth and neck portion 12 using various fitting methods without being affected by the characteristics of glass (large molding errors in molded products). In this embodiment, a first female screw portion 56 that meshes with the first male screw portion 14 is formed on the inner surface of the fitting portion 54, and the neck portion 12 and the fitting portion 54 are screwed together. By screwing the fitting portion 54 and the neck portion 12 together, the refill container 20 can be securely fitted into the container body 2, providing good fit. When replacing the refill container 20, the fitting portion 54 can be easily removed from the neck portion 12 by unscrewing it. In this specification, "fitting property" means that the fitting can be performed reliably or easily without causing any looseness due to glass forming errors or the like. However, the fitting type can be changed as appropriate. For example, it can be an undercut fitting as explained in the embodiment of Figure 4 described later, or, although not shown, it can be a knurling fitting in which one or both of the opposing surfaces of the mouth / neck portion 12 and the fitting portion 54 are made into rough surfaces with high friction resistance, such as knurled uneven surfaces, and they are fitted together.

[0024] The outer surface of the fitting portion 54 is arranged so as to be exposed to the outside, and serves as a gripping surface that is gripped by a user when replacing the refill container 20, for example. That is, when replacing the refill container 20, after removing the lid body 70, the container body 2 is supported with one hand, and the outer surface of the fitting portion 54 is grasped with the other hand and rotated in the opening direction.

[0025] In this embodiment, a vertical rib-like engaging protrusion 58 that fits between the pair of locking protrusions 10 is formed on the lower part of the inner surface of the fitting portion 54 . This engaging protrusion 58 is formed as a climbing rib that can climb over one of the pair of engaging protrusions 10 by rotating the inside plug 40, and is arranged so that it fits between both engaging protrusions 10 after climbing over one of the engaging protrusions 10. The pair of locking protrusions 10 and the engaging projection 58 form a circumferential locking means S that restricts the rotation of the inside plug 40 relative to the neck portion 12 . The circumferential locking means S serves to prevent the refill container 20, which is made up of the inside plug 40 and the contents-storing container body 22, from coming off the container body 2 when the lid body 70 is removed. In other words, when the container body 2 is held in one hand and the lid body 70 is rotated in the opening direction, the resistance of the circumferential locking means S causes the content storage container body 22 to remain within the container body 2, and the third female thread portion 79 unscrews from the third male thread portion 51. According to the above configuration, the user can recognize that the engaging protrusion 58 is properly engaged between the pair of engaging protrusions 10 by the feeling (click) that is felt when the engaging protrusion 58 passes over one of the engaging protrusions 10.

[0026] In the illustrated example, as shown in Fig. 1(B), a second mark M2 indicating information about the refill container (for example, the year of manufacture of the refill container) is printed on the outer surface of the fitting portion 54. This marking will be described later.

[0027] 3(B) shows an embodiment in which the refill container 20 is distributed independently through the product distribution process. The refill container 20 in this embodiment has a sealant 66 airtightly and releasably attached to the entire upper surface of the annular top plate portion 44. This sealant 66 may be, for example, an aluminum seal. By sealing the upper surface of the inside plug body 42 with the sealant 66, a plastic cap is no longer necessary. A handle 68 extends from one end of the sealing material 66, and the sealing material 66 can be peeled off from the mouth / neck portion 12 by pulling up the handle 68.

[0028] The lid 70 is detachably disposed on the top of the refill container 20. Here, "detachable" includes not only a mode in which it can be removed from the container body or the refill container body, but also a mode in which it is connected to the top of the container body via a hinge so that it can be opened and closed, for example, although this is not shown in the figure. The lid body 70 of this embodiment is composed of a first lid body 72 which is an inner lid and a second lid body 80 which is an outer lid. However, this structure can be modified as appropriate, and they may also be formed as a single member. The first lid 72 has a first cap peripheral wall 76 that hangs down from the peripheral edge of a first top plate 74 and a fitting peripheral wall 78 that hangs down from the underside of the first top plate 74 toward the inside of the first cap peripheral wall 76. The second lid 80 has a second cap peripheral wall 84 that hangs down from the peripheral edge of a second top plate 82. The first lid 72 is fitted into the second lid 80 . Further, a second anti-rotation means d2 is formed between the first cap peripheral wall 76 and the second cap peripheral wall 84 to prevent the second cover 80 from rotating freely relative to the first cover 72. In the illustrated example, the second anti-rotation means d2 is formed by fitting a locking protrusion provided on the outer surface of the first cap peripheral wall 76 into a recess formed on the inner surface of the second cap peripheral wall 84. However, this structure can be modified as appropriate. 1(A), a first mark M1 indicating information about the refill container (for example, the year of manufacture of the container) is printed on the top surface of the second top panel 82. This first mark M1 and the above-mentioned second mark M2 can prevent reuse after renewal. A third female thread portion 79 that meshes with the third male thread portion 51 is formed on the inner surface of the fitting peripheral wall 78 . A packing p is attached to the lower surface of the first top plate 74 inside the fitting peripheral wall 78 .

[0029] In the above configuration, in the state shown in Figure 1 (B), an O-ring is sandwiched between the annular top plate portion 44 and the mouth portion 30 by the screwing of the second male thread portion 32 and the second female thread portion 50, and the screwing of the third male thread portion 51 and the third female thread portion 79 causes the annular top plate portion 44 to be pressed against the gasket p on the underside of the first top plate 74, thereby ensuring the airtightness of the refill container 20. To remove the contents, from the state shown in FIG. 1(B), it is advisable to grip the outer surface of the fitting portion 54 of the inside plug 40 or the outer surface of the container body 2 with one hand and rotate the lid 70 in the opening direction. Then, the third female thread portion 79 is unscrewed from the third male thread portion 51, and the lid body 70 is removed from the inside plug 40, thereby opening the mouth portion 30 to the outside. Then, the contents can be taken out from the mouth portion 30. When replacing the refill container 20, first, the lid body 70 is removed from the inside plug 40 from the state shown in FIG. 1(B) as described above. Then, while supporting the container body 2 with one hand, the outer surface of the fitting portion 54 is gripped and rotated in the opening direction. This causes the first female thread portion 56 to unscrew from the first male thread portion 14, and the refill container 20 can be easily removed from the container body 2. During this operation, there is a gap g between the outer surface of the glass content storage container body 22 and the inner surface of the container main body 2, so no frictional force acts between these two surfaces to oppose the rotation and rise of the content storage container body 22 during the unscrewing operation. Furthermore, in this embodiment, the contents-storing container 22 is arranged in a suspended state within the container body 2, and when the refill container 20 is removed, it does not interfere with any part of the container body 2, but is linked only to the inner plug 40. Therefore, compared to the prior art structure in which a glass refill container is fitted into the container body, the contents-storing container 22 can be removed more easily. Then, by grasping the outer surface of the fitting portion 54 of a new refill container 20 shown in Figure 3 (B) that has been prepared in advance, the content storage container body 22 of the container is inserted into the container body 2, and the fitting portion 54 is lowered while rotating onto the outer surface of the mouth and neck portion 12, the first female thread portion 56 is screwed into the first male thread portion 14, and the refill container 20 can be securely fixed to the container body 2. While holding the outer surface of the fitting portion 54 with one hand, the handle portion 68 of the sealing material 66 attached to the mouth portion 30 of the new refill container 20 can be pulled up with the other hand to remove the sealing material 66 from the mouth portion 30. Then, when the lid body 70 is attached to the inside plug 40, the state shown in FIG. 1 is restored. When the refill container 20 has been used up, the third female thread portion 79 is unscrewed from the third male thread portion 51 by holding the body peripheral wall 26 with one hand and gripping the outer surface of the fitting portion 54 with the other hand and rotating it in the opening direction. By releasing the threaded engagement in this manner, the glass content-storing container body 22 can be easily separated from the inside plug 40, and the two can be easily disposed of separately.

[0030] According to the above-described configuration and operation, the separate inner plug 40 is assembled to the mouth 30 of the glass content-storing container body 22, and the fitting portion 54 extends downward and outward from the inner plug body 42 of this inner plug 40, and this fitting portion 54 is fitted into the mouth-neck portion 12 of the container body 2, resulting in good fitability. Since the inside plug 40 is screwed onto the mouth 30 of the contents-storing container body 22, it can be easily separated from the contents-storing container body 22 by unscrewing it, making it easy to separate and dispose of. Since a gap g is provided between the outer peripheral surface of the contents-storing container body 22 and the inner peripheral surface of the container main body 2, the refilling operation of the refill container 20 is easy.

[0031] Other embodiments of the present invention will be described below, and in these descriptions, explanations of structures that are the same as those in the first embodiment will be omitted.

[0032] 4 and 5 show a refill container according to a second embodiment of the present invention. In this embodiment, the configuration of the inner plug 40 employs an undercut fit instead of the thread fit of the first embodiment as the fit form of the fitting portion 54 to the neck portion 12, and the designs of the container body 2, contents-storing container body 22, and lid 70 have been changed. For ease of explanation, the design changes of the container body 2, contents-storing container body 22, and lid 70 will be explained first.

[0033] In this embodiment, the container body 2 is formed as a single container body. The container body 2 has a cylindrical peripheral wall 6 standing upright from the peripheral edge of the bottom wall 4, and a small outer diameter opening / neck portion 12 standing upright from the upper end of the cylindrical peripheral wall 6 via a first step portion 8. Furthermore, the content storage container body 22 of this embodiment is formed in a shape in which the outer diameter of the body wall 26 is approximately the same as the outer diameter of the mouth and neck portion 12, and does not have the structure of the second flange portion b2 and second step portion 28 described in the first embodiment. Furthermore, in this embodiment, the fitting peripheral wall 78 of the configuration of the lid body 70 described in the first embodiment is omitted, and the lower ends of the first cap peripheral wall 76 and the second cap peripheral wall 84 are extended to the vicinity of the first step portion 8. A first female thread portion 56 that engages with the first male thread portion 14 is formed on the inner surface of the lower part of the first cap peripheral wall 76, so that the lower part of the first cap peripheral wall 76 is screwed onto the outer surface of the mouth / neck portion 12.

[0034] Next, in this embodiment, the structure of the fitting portion 54 of the inside plug 40 is changed. Regarding the structures of the inside plug body 42 and the connecting portion 52, the explanation in the first embodiment is cited. The fitting portion 54 in this embodiment is suspended from an appropriate position (the inner portion in the illustrated example) on the underside of the flange-shaped connecting portion 52 attached to the inside plug body 42, along the inner peripheral surface of the mouth / neck portion 12, and is fitted into said inner peripheral surface. In this embodiment, a horizontal groove-like engagement groove 60 is formed on the outer surface of the fitting portion 54, and a horizontal rib-like locking protrusion 16 is formed on the inner surface of the mouth and neck portion 12. When the fitting portion 54 is inserted and fitted into the inner surface of the mouth and neck portion 12, the locking protrusion 16 is engaged in the engagement groove 60, and is configured to provide an undercut fit. In this specification, undercut fitting simply means a fitting configuration in which an undercut (locking protrusion) protruding from one of the opposing surfaces of the mating portion 54 and the mouth portion 30, which fit together, is formed to lock into a recess (engagement groove) provided on the other. The engagement groove 60 and the locking projection 16 form a vertical locking means R. The vertical locking means R serves to prevent the refill container 20 from coming off the container body 2 when the lid body 70 is removed. When removing the refill container 20 from the container body 2, the outer peripheral wall 48 of the inside plug body 42 is simply grasped and pulled up, causing the fitting portion 54 to elastically deform inward, separating the locking ridge 16 from the engagement groove 60 and releasing the undercut fit. Therefore, the inside plug 40 can be easily removed from the container body 2 by pulling it up. Similarly, when storing the refill container 20 in the container body 2, simply insert the lower half of the contents storage container body 22 into the container body 2 and fit the fitting portion 54 onto the inner surface of the mouth and neck portion 12. Therefore, the operation of attaching and detaching the fitting portion 54 to the mouth / neck portion 12 is simplified. As shown in FIG. 4(A), a gap (deformation allowance a) is provided between the fitting portion 54 and the contents-storing container body 22 to allow deformation of the fitting portion 54. The structure of the fitting portion 54 can be modified as appropriate, and a locking ridge 16 may be formed on the outer surface of the fitting portion 54, and an engagement groove 60 may be formed on the inner surface of the neck portion 12.

[0035] 6 shows a refill container according to a third embodiment of the present invention. This embodiment is based on the structure of the second embodiment, and has a knob 62 formed on the inside plug 40 and a storage recess 18 formed on the neck portion 12 for storing the knob. In the illustrated example, the gripping portion 62 is provided hanging down from the peripheral end of the connecting portion 52. The gripping portions 62 are preferably formed at two positions symmetrical with respect to the central axis of the refill container. The storage recess 18 is formed by cutting out the mouth / neck portion 12 in accordance with the shape of the grip portion 62. However, these structures can be modified as appropriate. A finger rest 64 is formed on the outer surface of the knob 62. The finger rest 64 in the illustrated example is formed to serve as a partial screw in place of the missing portion of the first male thread portion 14 of the neck opening / closing portion 12 that was created in order to form the storage recess 18. In the above configuration, when replacing the refill container 20, after removing the lid 70, the container body 2 is grasped and pulled up with the fingers hooked on the pair of knobs 62.
