Description

Technical Field

[0001] This invention relates to the field of manufacturing a dispensing system including a container connected to a closure device.

[0002] Specifically, the present invention relates to the field of manufacturing closure devices or caps suitable for closing said containers (such as bottles or tubes). Background Technology

[0003] Known prior art dispensing systems include various types of caps applied to bottles or tubes (such as shampoo, shower gel, toothpaste containers, etc.).

[0004] According to existing technology, the cap for such a container is made of plastic and consists of two parts: a body adapted to be attached to the container and a second movable part in the form of a lid. The two parts are advantageously hinged to each other, and the lid typically rotates relative to the body. The two parts are preferably manufactured as a single unit, thereby defining a single entity, which is preferably obtained by molding technology.

[0005] The body of the cap is connected to the opening area or neck of the container and is provided with a dispensing hole that can be closed and / or opened by moving / rotating the cap.

[0006] Typically, the body of the cap is applied to the open end area of ​​the container by pressure or by screwing it on.

[0007] In the closed position, the cover faces and completely covers the upper surface of the body.

[0008] However, existing technological solutions have some shortcomings.

[0009] One drawback of the known technology is the amount of material used to manufacture the two parts, including the cap.

[0078] Although the invention has been described below with reference to the embodiments shown in the accompanying drawings, the invention is not limited to the embodiments described below and shown in the drawings.

[0079] Instead, the embodiments described herein and illustrated in the accompanying drawings illustrate aspects of the invention, the purpose of which is defined by the claims.

[0080] The present invention has proven particularly advantageous when applied to closure devices suitable for containing products in fluid form, such as body care products (e.g., shampoo, shower gel, toothpaste) or cosmetics (e.g., creams and similar products). More preferably, the invention has proven particularly advantageous when applied to closure devices made of plastic and obtained by molding techniques. However, it should be noted that the invention is not limited to this application. Rather, the invention can be readily used in any application requiring the use of closure devices for containers suitable for containing easily dispensable fluid products (e.g., deodorants, hair removal creams); or for pharmaceutical or veterinary products; or for cooking products (e.g., mayonnaise, sauces); and even for adhesives, etc.

[0081] The following is for reference. Figures 1 to 7 A first embodiment of the closing device 10 is described, which is also referred to herein as a cap and is implemented according to the invention; in the drawings, similar or equivalent features and / or components are identified by the same reference numerals.

[0082] Figure 1 A closure device 10 according to an embodiment of the present invention is shown, which is applied to a container 4 to form a component 1. In this figure, the closure device 10 is in its closed configuration, that is, the closure device is closed.

[0083] Figure 2 The same closing device 10 applied to container 4 in its open configuration is shown.

[0084] The container 4 shown in the figure is a generally cylindrical container used to hold, for example, bath liquid.

[0085] Container 4 is preferably made of plastic material.

[0086] Plastics suitable for this purpose are preferably composed of polypropylene (PP), polyethylene (PELLD, PELD, PEMD, PEHD) and other materials known as ABL, PBL, PCR, soft-touch resins.

[0087] However, in variant embodiments, the container may have a different shape than that indicated and / or described in the preferred embodiment and / or be made of a different material than that indicated and / or described in the preferred embodiment. The container may also be used to dispense other types of products, such as products preferably in fluid form, such as body care products (e.g., shampoo, toothpaste) or cosmetics (e.g., beauty creams).

[0088] Container 4 has a head surface 4a or neck portion at its upper end, in which an opening for filling and dispensing product is present (not visible in the figure). In the illustrated embodiment, the neck portion 4a preferably has a cylindrical shape. However, in variant embodiments, the neck portion 4a may have any other shape.

[0089] The closing device 10 is advantageously applied to the container 4 by a suitable connecting device 20 (e.g., by thread), as better described below.

[0090] However, in alternative embodiments, the cap may be connected to the container in different ways (e.g., via snap-fit ​​connectors or equivalent connectors).

[0091] For this purpose, the neck portion 4a at the upper end of the container 4 is provided with a corresponding connecting device suitable for connecting the cap 10, which is not shown in the figure.

[0092] exist Figures 3 to 6 As can be clearly seen, the cap 10 includes a body 12 and a cover 32 hinged to the body 12.

[0093] The main body 12 can be connected to the container 4, and the main body is preferably connected to the neck portion 4a of the container 4, as described above.

[0094] The main body 12 has an inner surface 14 (in Figure 6 (more clearly visible in the middle) and the outer surface 16 opposite to the inner surface 14. When the cap 10 is attached to the container 4, the inner surface 14 is adapted to face the container 4.

[0095] The main body 12 preferably also includes a through opening 18 located between the outer surface 16 and the inner surface 14 for allowing products from the container 4 to pass through.

[0096] The main body 12 is also preferably provided with a connecting device 20 for connecting to the container, and more preferably with a connecting device for connecting to the neck portion 4a of the container 4.

[0097] The connecting device 20 is preferably defined by a neck portion 22 of the body 12, which extends from the inner surface 14 of the body toward the container 4.

[0098] Preferably, the neck portion 22 has a cylindrical shape. However, in variant embodiments, the neck portion 22 may have different shapes.

[0099] The connecting device 20 preferably allows the cap 10 to be threadedly connected to the container 4. The connecting device 20 preferably includes a nut thread portion 21 formed internally at the level of the neck portion 22. The neck portion 4a of the container 4 is advantageously provided with a corresponding thread portion formed on the neck portion 4a of the container 4.

[0100] In alternative embodiments, the connecting device may be of a different type, for example by providing an appropriate undercut engagement area in the neck portion of the cap and container.

[0101] As for the cover 32, the cover is hinged to the body 12 at the level of the hinge region 33.

[0102] According to one aspect of the invention, the body 12 and the cover 32 are manufactured to be integrated with each other. Preferably, the body 12 and the cover 32 are manufactured by injection molding of plastic material so that the body and the cover are integrated with each other.

[0103] Plastics suitable for this purpose are preferably composed of polypropylene (PP) and / or polyethylene (PELLD, PELD, PEMD, PEHD).

[0104] Due to this configuration of the body 12 and the cover 32, the cover 32 can be moved, and in this case, rotated, to be positioned in a closed position relative to the body 12 (e.g., as shown in the image). Figure 1 , Figure 3 or Figure 6 (as shown) and at least one open position (e.g., as shown) Figure 2 , 4 (or as shown in 7).

[0105] The cover 32 preferably includes an inner surface 34 facing the body 12 and an outer surface 36 opposite to the inner surface 34. When the cover 32 is in its closed position, the inner surface 34 faces the body 12.

[0106] The cover 32 preferably includes a closure device 40, which is adapted to close the through opening 18 of the body 12 when the body 12 is in the closed position.

[0107] The closing device 40 preferably includes a reference element 42, which is adapted to block the through opening 18 when the body 12 is in the closed position and preferably inserted into the through opening 18.

[0108] Preferably, the shape of the cover 32 substantially matches the shape of the body 12, so that in the closed position, the cover 32 precisely overlaps the body 12 and completely covers the body.

[0109] According to one aspect of the invention, the cover 32 includes a through opening 50 formed between its outer surface 36 and its inner surface 34.

[0110] According to an advantageous aspect of the invention, the through opening 50 is shaped such that at least a portion 60 of the outer surface 16 of the body 12 is visible in the closed position of the cover 32 relative to the body 12.

[0111] Advantageously, by forming the through opening 50, the use of raw materials for producing the cover 32 and thus the cap 10 can be reduced, thereby reducing the weight of the cover and thus the cap and / or reducing production costs.

[0112] According to a preferred embodiment of the present invention, for example Figures 1 to 7 As shown, at least one portion 60 of the outer surface 16 of the body 12 is defined by a region protruding from the same outer surface 16 of the body 12, as Figure 4 , Figure 5B and Figure 6 As can be seen, when the cover 32 is in the closed position relative to the body 12, the protruding region 60 is preferably adapted to be inserted into the through opening 50 of the cover 32, such as... Figure 6 cross-sectional view and Figure 3 As shown.

[0113] Preferably, the protruding region 60 of the body 12 and the through opening 50 of the cover 32 have matching shapes, such that the shape of the protruding region 60 matches or substantially matches the shape of the through opening 50 of the cover 12. Figures 1 to 7 In the preferred embodiment shown, the protruding region 60 is substantially elliptical in shape. Obviously, in variant embodiments, some of which are described below, the shape may be different.

[0114] Advantageously, by ensuring that the protruding area 60 of the body 12 matches or substantially matches the through opening 50 of the cover 32, the desired stability of the cover 32 in the closed position above the body 12 is obtained and / or maintained.

[0115] According to an advantageous aspect of the invention, at least one portion 60 of the outer surface 16 of the body 12 and the outer surface 36 of the cover 32 are shaped such that a continuous or substantially continuous surface is formed. This is in Figure 6 This is particularly evident in the fact that the surface is smooth from the outside 36 of the cover 32 to the outside 16 of the body 12 defined by the protruding area 60, or in other words, there are no uneven parts.

[0116] Advantageously, the formation of the continuous or substantially continuous surface firstly provides the cap with a unique feature of continuity and a unified overall aesthetic.

[0117] Furthermore, preferably, the absence of varying levels on the surface minimizes the area where dust / dirt could accumulate on the cap.

[0118] According to another advantageous aspect of the invention, the thickness SP of the body 12, defined between its inner surface 14 and outer surface 16, remains constant or substantially constant along the entire length of the body, particularly at the level of the protruding region 60, as... Figure 6As shown. In other words, the protruding region 60 does not constitute an area of ​​added material for the body 12, but rather constitutes a "displacement" of material that allows the thickness of the body 12 to remain constant.

[0119] Furthermore, advantageously, the total thickness ST of the cap 10, intended to be the thickness between the inner surface 14 of the body 12 and the outer surface 36 of the cover 32, preferably has a first thickness ST1, while the total thickness ST2 of the cap 10 at the level of the through opening 50 is the same thickness SP as the thickness of the protruding area 60.

[0120] Therefore, the total thickness ST2 of the cap 10 at the level of the through opening 50 is less than the total thickness ST1 of the cap 10 outside the through opening 50.

[0121] Advantageously, compared to the total thickness of a known type of cap, the thickness of the cap according to the new solution is reduced, and therefore the material and / or weight of the cap is reduced, while the total thickness of the known type of cap is substantially constant along the entire length of the body and the cap (since the cap has no through opening, the thickness is everywhere the sum of the thicknesses of the body and the cap).

[0122] According to another aspect of the invention, the cover 32 and the body 12 are integrated into one unit, such that the hinge region 33 and the through opening 18 of the body 12 are positioned on opposite sides relative to the central axis X passing through the cap 10. Therefore, preferably, the hinge region 33 and the reference element 42 are also positioned on opposite sides relative to the central axis X passing through the cap 10.

[0123] Advantageously, when the user pushes the cover 32 to open the cap 10, the gripping area 64 of the cover 32, located on the opposite side of the hinge region 33, is near the through opening 18 and the reference element 42, such that during the pushing phase, the mechanical deformation of the cover 32 itself is limited as much as possible when the cover 32 is pushed to open the cap 10. In fact, the point of application of the opening force at the level of the gripping area 64 is close to the resistance region formed by the reference element 42, which is inserted into the through opening 18 in an interfering manner.

[0124] In a preferred embodiment, at least the body 12 is made of a transparent material. This allows the interior of the container 4 to be seen through the through opening 50 of the lid 32 and the transparent portion 60 or protruding area 60 of the body 12. The through opening 50 and the transparent portion 60 of the lid 32 define an inspection hole that allows inspection of the contents of the container 4 to assess, for example, the remaining amount of product.

[0125] In a preferred variant embodiment, the body 12 is not entirely transparent, but only a portion 60 or the protruding area 60 is transparent, thereby preferentially and advantageously achieving the inspection hole effect in any case.

[0126] Furthermore, in a preferred embodiment, the body 12 and the cover 3 are made of different colors. Advantageously, an attractive aesthetic effect can be achieved from the color contrast between the color of the body 12 as seen from the opening 50 of the cover 32 and the color of the cover 32 itself.

[0127] According to another advantageous aspect of the invention, the through opening 50 of the cap 32 is shaped to substantially define an eyelet in which at least one connecting region 70 is identified, the connecting region being adapted to allow the cap 10 in the open position to be connected to the connecting element G or hook G (see...). Figure 7 ).

[0128] Advantageously, when the cap 10 is open, simply opening the lid 32 allows for easy hanging of component 1, consisting of container 4 and cap 10, onto hook G. This is particularly useful during use of component 1, for example, when repeated dispensing of the product contained therein is desired, or for temporary positioning of component 1 before it is fully closed, such as during showering, where the product in component 1 includes shower gel or shampoo and the component can be hung on a dedicated hook G in the shower. Therefore, it is advantageous to manipulate component 1 during its use.

[0129] Preferably, the connecting area 70 consists of at least one intermediate surface 35, which engages the outer surface 36 and inner surface 34 of the through opening 50 of the cover 32, such as... Figure 4 As shown.

[0130] According to another advantageous aspect, in addition to the through opening 18 for allowing product from container 4 to pass through, body 12 also includes at least one through opening 15a, 15b formed between the outer surface 16 and the inner surface 14 of body 12, such as Figure 5C The variant embodiment is shown.

[0131] Advantageously, compared with caps known in the art, the amount of material used in producing the body 12 is reduced, and thus the amount of material used in producing the cap 910 is also reduced.

[0132] Furthermore, for example, regarding the first embodiment of the cap 10 in... Figure 5C As shown, the through opening of the body 12 can be made in any of the embodiments shown and described below (see reference). Figure 39 (Example shown).

[0133] Figures 8 to 10 A first variant embodiment of the cap 110 of the present invention is shown.

[0134] Features and / or components corresponding to or equivalent to the features and / or components of the embodiments described above are identified by the same reference numerals, and the same is true for the different variant embodiments shown and described below, wherein features and / or components corresponding to or equivalent to the features and / or components of the embodiments described above are identified by the same reference numerals.

[0135] First variant embodiment and reference Figures 1 to 7 The difference between the described embodiments is mainly due to the fact that the through opening 50 of the cover 32 and the corresponding protruding area 60 of the body 12 both have the same characteristics as the reference. Figures 1 to 7 The described embodiments have different shapes and sizes, and both the through opening and the corresponding protruding area are substantially circular rather than elliptical.

[0136] This also applies to Figures 11 to 13 The second variant embodiment of the cap 210 shown.

[0137] Figures 14 to 16 A third variant embodiment of the cap 310 of the present invention is shown.

[0138] The variant embodiments and references Figures 1 to 7 The reason for the difference in the described embodiments is that the through opening 50 of the cover 32 and the corresponding protruding area 60 of the body 12 both have the same characteristics as the reference. Figures 1 to 7 The described embodiments have different shapes and sizes, and the neck portion 22 of the body 12 also has different shapes, which are elliptical rather than cylindrical.

[0139] Figures 17 to 19 A fourth variant embodiment of the cap 410 of the present invention is shown.

[0140] The variant embodiments and references Figures 1 to 7 The reason for the difference in the described embodiments is that the through opening 50 of the cover 32 and the corresponding protruding area 60 of the body 12 both have the same characteristics as the reference. Figures 1 to 7 The described embodiments have different shapes and sizes, and the neck portion 22 also has different shapes. Both the through opening and the corresponding protruding area are generally rectangular / square, and the neck portion is also square / rectangular.

[0141] Figures 20 to 22 A fifth variant embodiment of the cap 510 of the present invention is shown.

[0142] The variant embodiments and references Figures 1 to 7 The difference between the described embodiments lies in the fact that the through opening 50 of the cover 32 and the corresponding protruding area 60 of the body 12 both have the same characteristics as the reference. Figures 1 to 7The described embodiments have different shapes and sizes, and the neck portion 22 has a different shape and is elliptical, and the reason is that the cover 32 has a reduced size relative to the body 12 located below, so that the side portions 16a, 16b of the outer surface 16 of the body 12 are still visible in the closed position.

[0143] Figures 23 to 25 A sixth variant embodiment of the cap 610 of the present invention is shown.

[0144] The variant embodiment illustrates another feature of the invention, namely, that the cover 32 is equipped with a coupling device 650 to provide another area suitable for coupling the cap 610 and the components including the container with a possible hook G.

[0145] The connecting device 650 preferably includes a curved surface portion 652 extending outward from the cover 32.

[0146] Figures 23 to 25 The embodiment of the cap 610 shown basically corresponds to Figures 14 to 16 The cap 310 shown is provided with the connecting device 650. It should be noted that any embodiment according to the present invention may be equipped with the other connecting device 650.

[0147] Furthermore, in a variant embodiment, the connecting device formed by the curved surface 652 can have any other shape suitable for this purpose.

[0148] Figures 26 to 28 A seventh variant embodiment of the cap 710 of the present invention is shown.

[0149] The variant embodiments and references Figures 1 to 7 The reason for the differences in the described embodiments is that the through opening 50 of the cover 32 has a different shape and size and the upper part 16 of the body 12 is flat, i.e., without any protruding areas.

[0150] Figures 29 to 31 An eighth variant embodiment of the cap 810 of the present invention is shown.

[0151] The variant embodiments and references Figures 1 to 7 The difference in the embodiments is that the upper part 16 of the body 12 is flat, i.e., without any protruding areas, and because the cover 32 has four openings 50a-50d, each of which is generally fan-shaped, and also because the through opening 18 of the body 12 and the reference element 42 of the cover 32 are positioned at the center of the cap 810 and preferably along the central axis X of the cap.

[0152] Figures 32 to 35 A ninth variant embodiment of the cap 910 of the present invention is shown.

[0153] The variant embodiments and references Figures 1 to 7 The main reason for the difference in the described embodiments is that the size of the body 12 is smaller than the size of the cover 32.

[0154] Advantageously, compared with caps known in the art, the amount of material used in producing the body 12 is reduced, and therefore the amount of material used in producing the cap 910 is also reduced.

[0155] In the closed position, the cover 32 is stacked on the body 12, thereby completely covering the body, and the cover 32 extends beyond the extension of the body 12 located below.

[0156] Therefore, except as described above, in the closed position of the cap 910, at least a portion of the upper surface 4b of the container 4 directly faces the corresponding portion 34a of the inner surface 34 of the cap 32, without being inserted into the body 12. Figure 35 The portion 34a is shown in component 1001 and the portion substantially corresponds to the surface 34a of the inner surface 34 outside the dashed area (which substantially corresponds to the outer perimeter of the body 12).

[0157] Figures 36 to 38 A tenth variant embodiment of the cap 1010 of the present invention is shown.

[0158] The variant embodiments and references Figures 32 to 35 The described embodiment differs primarily because the through opening 50 of the cover 32 and the corresponding protruding region 60 of the body 12 (annular fan shape rather than an elliptical shape) both have the same characteristics as the reference. Figures 32 to 35 The described embodiments have different shapes and sizes. The size of the body 12 is still smaller than the size of the cover 32. (Refer to reference...) Figures 32 to 35 Compared to the described embodiment, the dimensional difference between the cover 32 and the body 12 is smaller.

[0159] Figure 39 References are shown Figures 36 to 38 A variant embodiment of the cap 1010 of the present invention is described, wherein, in addition to a through opening 18 intended for allowing product from container 4 to pass through, the body 12 also includes at least one through opening 15a, 15b formed between the outer surface 16 and the inner surface 14 of the body 12.

[0160] Therefore, it is clear from the description provided above that the closure device, which is the subject of the present invention, enables the achievement of a predetermined purpose and, in particular, enables a reduction in the amount of material required for the production of the closure device, as well as a reduction in its weight and / or a reduction in production costs, compared to devices known in the art.

[0161] Although the invention has been described with reference to specific embodiments shown in the accompanying drawings, it should be noted that the invention is not limited to the specific embodiments shown and described herein; rather, further variations of the embodiments described herein fall within the scope of the invention as defined by the claims.
