DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In each drawing, unless otherwise specified, the same or corresponding components may be denoted by the same reference numerals and the description thereof may be omitted. In addition, the drawings are schematic to facilitate understanding of the invention.

[0011] A cap structure according to an embodiment will be described. Fig. 1 is a perspective view of a container having a cap structure according to an embodiment, Fig. 2 is an exploded perspective view of a container having a cap structure according to an embodiment, and Fig. 3 is a perspective view of a container having a cap structure according to an embodiment with a lid part opened. Fig. 4 is an enlarged cross-sectional view of a main part of a container having a cap structure according to an embodiment. Fig. 5 is an explanatory view showing the position of a pouring outlet of a cap structure according to an embodiment.

[0012] As shown in FIGS. 1 to 3, the container 1 includes a container body 2 and a cap structure 3 attached to the container body 2 and having a spout 22.

[0013] The container body 2 is a container with an open top and contains the contents. As shown in FIG. 4, the container body 2 has a neck portion 4 protruding from the top, and the above-mentioned opening is formed in the neck portion 4. A male screw 5 is formed on the outer circumferential surface of the neck portion 4. In this embodiment, a cylindrical container body 2 is shown, but the shape of the container body 2 can be any shape, for example, it may be a tube-shaped container. The material of the container body 2 can be selected according to the contents, the purpose, etc., and for example, metals such as aluminum, resins, etc. can be used. As the resin, for example, polyethylene, ethylene-vinyl alcohol copolymer, polyvinylidene chloride copolymer, polyethylene terephthalate, polyamide, polyacrylonitrile, etc. can be used. The container body 2 may be a single-layer structure of the above-mentioned materials, or a laminated structure of different materials.

[0014] Furthermore, the container body 2 may be a refill container that is detachable from the cap structure 3, and after the contents have been poured out, the cap structure 3 can be removed from the empty container body 2, and the container body 2 filled with the contents can be screwed onto the cap structure 3. When the container body 2 is detachable from the cap structure 3, for example, even if the container body 2 is made of metal and the cap structure 3 is made of resin, they can be separated and disposed of at the time of disposal.

[0015] The contents dispensed by the container 1 according to this embodiment are not limited as long as they exhibit fluidity at least when dispensed and can be pushed out of the container 1 from the dispensing outlet 22 of the container 1. The contents may be liquid, for example, a liquid of a pure substance or a liquid mixture. Furthermore, the contents may be, for example, a solution, and a dispersion such as an emulsion or suspension, and may be in a state called a gel, a slurry, a paste, a cream, or the like. The contents may contain a powder, or may mainly contain a powder, or may be substantially composed of a powder or consist of a powder. The contents may also be a paste or cream having a viscosity similar to or higher than that of water.

[0016] The contents may be skin care products or basic cosmetics such as lotion, milky lotion, face cream, serum, facial cleanser, cleansing agent, etc.; makeup cosmetics such as foundation, makeup base, concealer, liquid eye shadow, liquid blush, liquid lip product, etc.; personal care products (hygienic products) such as sunscreen, hand soap, body soap, hair shampoo, hair dye, styling agent, hand cream, body cream, body lotion, etc.; fragrance products, etc.

[0017] The cap structure 3 has a fixing member 10 that can be fixed to the mouth / neck portion 4 of the container body 2, and a rotating member 20 that is attached to the fixing member 10 so as to be rotatable relative to the fixing member 10.

[0018] The fixing member 10 has an upper tube portion 12 erected on the upper surface, an inner tube portion 16 formed with a female screw 17 that screws with the male screw 5 of the mouth-neck portion 4 of the container body 2, and an outer tube portion 14 arranged concentrically with the inner tube portion 16. In other words, the mouth-neck portion 4 and the fixing member 10 are screwed together. The peripheral surface of the upper tube portion 12 and the peripheral surface of the outer tube portion 14 are formed with annular convex portions 13 and 15 that extend in the circumferential direction, respectively. The fixing member 10 has an opening 11 in the center of the upper surface that communicates with the inside of the mouth-neck portion 4 of the container body 2 (the opening of the container body 2). The opening 11 is included within the opening range of the mouth-neck portion 4. In FIG. 4, the central axis 7 of the opening 11 and the central axis of the mouth-neck portion 4 coincide with each other, but as long as the opening 11 is included in the opening range of the mouth-neck portion 4, the central axes of the two may be offset. A protrusion that is pointed toward the container body 2 side may be formed at the lower end of the opening 11. As a result, when the opening of the container body 2 is sealed (not shown), by attaching the fixing member 10 to the mouth and neck portion 4 of the container body 2, the protruding portion can break through the seal of the container body 2, making it possible to easily open the seal of the container body 2.

[0019] The rotating member 20 has a base 21 rotatably connected to the fixed member 10, and an openable and closable lid 27 connected to the base 21. The base 21 and the lid 27 may be integrally molded or may be separate members. The base 21 has a peripheral wall 25 and an inner cylinder 23 located closer to the rotation axis than the peripheral wall 25. Annular convex portions 24 and 26 extending in the circumferential direction are formed on the peripheral surface of the inner cylinder 23 (the peripheral surface facing the peripheral surface of the upper cylinder 12 of the fixed member 10) and the peripheral surface of the peripheral wall 25 (the peripheral surface facing the peripheral surface of the outer cylinder 14 of the fixed member 10). When the rotating member 20 is pressed against the fixed member 10 from above, the annular convex portions 24 and 26 of the base 21 overcome the annular convex portions 13 and 15 of the fixed member 10, respectively, and the inclined surfaces of the convex portions engage with each other, so that the fixed member 10 and the base 21 are tightly connected to each other. As a result, the rotating member 20 including the base 21 or the lid 27 is fixed to the fixed member 10 so as to be rotatable relative to the rotating direction and undetachable in a direction perpendicular to the rotating direction. In the present embodiment, an example in which an annular convex portion is formed on both the circumferential surface of the upper tube portion 12 of the fixed member 10 and the circumferential surface of the inner tube portion 23 of the base 21 is shown, but an annular convex portion may be formed on one of them and a recessed portion may be formed on the other. In addition, in the present embodiment, an example in which an annular convex portion is formed on both the circumferential surface of the outer tube portion 14 of the fixed member 10 and the circumferential surface of the peripheral wall 25 of the base 21 is shown, but an annular convex portion may be formed on one of them and a recessed portion may be formed on the other.

[0020] The rotating member 20 has, on its upper surface, a spout 22 that communicates with the inside of the mouth-neck portion 4 of the container body 2 and the opening 11 of the fixed member 10. As shown in FIG. 5(a), the spout 22 is formed at a position offset radially outward from the central axis of the base 21, and the central axis 6 of the spout 22 and the central axis 7 of the opening 11 of the fixed member 10 are in an offset positional relationship. In other words, the spout 22 is eccentric with respect to the opening 11. There is no particular restriction on the magnitude of offset (eccentric distance) of the spout 22 with respect to the opening 11, and it can be set arbitrarily depending on the size of the container body 2 and the size of the mouth-neck portion 4 of the container body 2, but it is preferable that the eccentric distance is, for example, 1.0 mm or more. When the base 21 is rotated relative to the fixed member 10 by, for example, 180 degrees in a predetermined direction, it is positioned as shown in FIG. 5(b). Since the spout 22 is formed in the arrangement described above, the user can align the spout 22 to a desired position by rotating the base 21 relative to the fixing member 10, without having to change the position of the container 1 held in the hand or increase the inclination angle of the container 1. In addition, since the spout 22 can be positioned close to the object on which the contents are placed, such as the palm of the hand, it is easy to pour the contents onto the object, improving convenience.

[0021] Furthermore, the rotating member 20 has a space 30 between itself and the upper surface of the fixed member 10 through which the contents flow. The contents pushed out from the container body 2 pass through the opening 11 of the fixed member 10, and then pass through the space 30 between the fixed member 10 and the rotating member 20, and are poured out from the spout 22. As described above, the central axis 6 of the spout 22 and the central axis 7 of the opening 11 of the fixed member 10 are misaligned, so that the contents flow in a crank shape through the space 30. This allows the contents to be poured out slowly.

[0022] The lid 27 is connected (hinged) to the base 21 via the hinge 28, and can be opened and closed with the hinge 28 as a base point. The lid 27 and the hinge 28 are preferably integrally molded. When the container 1 is not in use, the lid 27 covers the base 21 and is closed as shown in FIG. 1, and when the container 1 is in use, the lid 27 is separated from the base 21 by rotating with the hinge 28 as a base point, as shown in FIG. 3, and the spout 22 is opened by maintaining the separated state. In order to maintain the separated state of the lid 27 from the base 21, the hinge 28 may be configured to be biased in a direction in which the lid 27 moves away from the base 21. This allows the user to open and close the lid 27 with one touch, that is, by lifting the end of the lid 27 opposite the hinge 28, to form a one-touch openable and closable container 1. When closing the lid portion 27, the lid portion 27 can be locked to the base portion 21 of the rotating member 20 by placing a hand (fingers) on the upper surface side of the lid portion 27 and pressing it against the biasing force. Note that it is possible to configure the hinge 28 so that no biasing force acts on it, in which case it is necessary to rotate the lid portion 27 backward by hand. Note that when the lid portion 27 and the base portion 21 are configured as separate members, for example, the hinge 28 may be a separate member from the lid portion 27 and the base portion 21, such as a hinge pin, and the lid portion 27 and the base portion 21 may be joined by pinning or the like.

[0023] The lid 27 has an insertion portion 29 that fits into the spout 22 as a sealing means capable of sealing the spout 22. By closing the lid 27, the insertion portion 29 fits into the spout 22, and the spout 22 can be sealed. In this embodiment, an example has been shown in which the sealing means capable of sealing the spout 22 is the insertion portion 29 that fits into the spout 22, but the sealing means may be a sealing means that fits externally to the outer periphery of the spout 22. In FIG. 4, an outwardly opening inclined surface is formed on the outlet side inner periphery of the spout 22, and the structure is such that the insertion portion 29 can easily fit into the spout 22 when the lid 27 is closed. However, when the insertion portion 29 is to be externally fitted, the above-mentioned outwardly opening inclined surface is not necessary, and it is sufficient to form a tapered inclined surface on the outer periphery of the spout 22.

[0024] When lid 27 is in a state where rotating member 20 is closed, the position of spout 22 when lid 27 is opened can be guessed from the position of hinge 28, etc. However, for example, by attaching a sticker to the top surface of lid 27 at a position corresponding to the position of spout 22 or by providing a mark (logo mark or opening mark) on the top surface of lid 27 so that the position of spout 22 can be known even when lid 27 is closed, it becomes possible to adjust the position of spout 22 before opening lid 27 with a single touch.

[0025] Next, a modified example of the engagement portion between the container body 2 and the fixing member 10 will be described. FIG. 6 is an enlarged cross-sectional view of a main part showing a modified example of the engagement portion between the container body 2 and the fixing member 10 of the container 1 having the cap structure 3 according to one embodiment. In this embodiment, the container body 2 and the fixing member 10 are joined by screw joining, but as shown in FIG. 6, a fitting protrusion 8 may be provided on the outer peripheral surface of the mouth neck part 4 of the container body 2, and a fitting recess 18 may be provided on the inner peripheral surface of the inner tube part 16 of the fixing member 10, and the fitting protrusion 8 and the fitting recess 18 may be joined by non-detachable fitting. When the container body 2 and the fixing member 10 are made non-detachable, the method is not limited to the modified example shown in FIG. 6, and the fixing member 10 and the container body 2 may be joined by insert molding, which can reduce the number of assembly steps.

[0026] Next, modified examples of the fixing member 10 will be described. Fig. 7 is an enlarged cross-sectional view of a main part showing a modified example of the fixing member 10 of the cap structure 3 according to one embodiment. In this embodiment, the opening 11 of the fixing member 10 is formed at a right angle at the upper edge in a cross section including the central axis 7, but as shown in Fig. 7, an inclined portion 19 inclined toward the central axis 7 may be formed. This makes it easier to return the contents accumulated in the space 30 into the container body 2 after the container 102 has been used.

[0027] Although the embodiment has been described above, the above embodiment is presented as an example, and the present invention is not limited to the above embodiment. The above embodiment can be implemented in various other forms, and various combinations, omissions, substitutions, modifications, etc. can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.
