Technical Field
[0001] The present invention relates to a receptacle comprising a container and a cap, the cap being repeatedly attached to the container for sealing the container. Background Technology
[0002] This type of container is used in many applications, including packaging for beauty products such as mascara. Various systems are known for attaching the cap to the reservoir, such as shaped threads, bayonet locks, rotating caps that engage with slots, wire hangers as clamps, eccentric handles for compression seals, or bistable snap-on caps.
[0003] The systems mentioned above are complex in shape, difficult to manufacture, or require more parts. A container is needed that allows for a simple, quick, and reliable way to attach the cap to the reservoir. Summary of the Invention
[0004] This need is met by a container according to claim 1, and particularly by a container comprising a reservoir and a cap, the cap being repeatedly attached to the reservoir for sealing the container, the cap having a channel having an opening formed therein, the reservoir having a neck for insertion into the channel along the longitudinal axis of the container via the opening of the cap, wherein the opening of the cap has an inner contour of a non-circular shape complementary to the non-circular outer contour of the neck.
[0005] The inner circumferential surface of the channel and the outer circumferential surface of the neck are formed such that an axial form fit can be produced by rotating the cap about the longitudinal axis relative to the reservoir.
[0006] Furthermore, the inner circumferential surface of the channel and the outer circumferential surface of the neck are formed such that after the cap and the neck are in a form-fit engagement, a press-fit engagement in the radial direction between the inner circumferential surface of the channel and the outer circumferential surface of the neck can be generated by rotating the cap about the longitudinal axis relative to the reservoir.
[0007] The present invention is based on the following concept: the cap and the reservoir are attached to each other in such a way that a form-fit engagement is first created in the axial direction, for example, similar to a thread, and then a press-fit engagement is created, unlike a thread, by rotating the non-circular section of the channel in the cap relative to the non-circular section of the neck of the reservoir, thereby creating the press-fit engagement in the radial direction between the inner circumferential surface of the channel and the outer circumferential surface of the neck.
[0008] Embodiments of the container are defined by the dependent claims and described in the following disclosure.
[0009] The inner contour of the cap, which is a non-circular shape, may extend along a segment of the passage or substantially the entire passage. Similarly, the outer contour of the neck, which is a non-circular shape, may extend along a segment of the neck or substantially the entire neck.
[0010] According to one embodiment, the outer circumferential surface of the neck is formed as the outer circumferential surface of a twisted non-circular element; and the inner circumferential surface of the channel is correspondingly formed as the inner circumferential surface of a twisted non-circular tube, specifically a twisted non-cylindrical tube, which is twisted such that a section of the tube in a plane perpendicular to the longitudinal axis is non-circular, allowing the cap to be attached to the neck of the reservoir. In other words, the neck has a non-circular cross-section with a constant dimension along the longitudinal axis, but the orientation of the non-circular cross-section continuously changes, such that surface points equidistant from the longitudinal axis of the neck are arranged in a spiral pattern.
[0011] According to a second aspect, a container is provided comprising a reservoir and a cap, wherein the cap is repeatedly attached to the reservoir for closing the container, the cap having a channel having an opening formed therein, and the reservoir having a neck for insertion into the channel along the longitudinal axis of the container via the opening of the cap, wherein the opening of the cap has an inner contour of a non-circular shape complementary to the non-circular outer contour of the neck.
[0012] The outer peripheral surface of the neck is formed as the outer peripheral surface of a twisted non-circular element;
[0013] Furthermore, the inner circumferential surface of the channel is correspondingly formed as the inner circumferential surface of a twisted non-circular tube, such that the cap can be attached to the neck of the reservoir by rotating the cap relative to the reservoir.
[0014] According to one embodiment, the non-circular contour of the neck and / or channel has a symmetrical circumferential shape. This circumferential shape can be mirror-symmetric, for example, it can be oval. This allows the cap to be attached to the neck from two different angular positions. Alternatively, the circumferential shape can be rotationally symmetric, for example, it can be shaped like a hyperbolic polygon, such as a triangle. This simplifies attaching the cap to the neck because it allows the cap to be placed on the neck at, for example, three different angular positions.
[0015] According to another embodiment, the inner circumferential surface of the channel and the outer circumferential surface of the neck are formed and / or configured such that by rotating the cap about the longitudinal axis relative to the reservoir, the cap is pushed toward the reservoir along the longitudinal axis. This allows the cap to be easily attached to the neck of the reservoir.
[0016] To create a press-fit engagement between the neck and the cap in the radial direction, the inner circumferential surface of the channel may have multiple concave surfaces, and the outer circumferential surface of the neck may have corresponding convex circumferential surfaces. These surfaces allow the cap to be snapped onto the neck by rotating the cap relative to the neck of the reservoir. In particular, this should only be possible in normal operation when the cap is fully attached to the neck of the reservoir.
[0017] Generally, in order to attach the cap to the reservoir and detach the cap from the reservoir relatively quickly, the outer circumferential surface of the neck can be formed as the outer circumferential surface of a non-circular element twisted 360° or less, and the inner circumferential surface of the channel can be correspondingly formed as the inner circumferential surface of a non-circular tube twisted 360° or less.
[0018] To achieve a quick-locking function—that is, to enable rapid attachment and detachment of the cap from the reservoir—the outer circumferential surface of the neck can be formed as the outer circumferential surface of a non-circular element twisted approximately 180°, and the inner circumferential surface of the channel can be correspondingly formed as the inner circumferential surface of a non-circular tube twisted approximately 180°. This allows the cap to be fully attached to the reservoir neck by rotating it approximately half a turn relative to the neck. After full attachment to the neck, a press-fit engagement can be achieved by continuing to rotate the cap 5° to 20° relative to the neck.
[0019] In order to have a smooth outer surface on the neck that can be easily cleaned, the contour of the neck along the longitudinal axis and / or circumferential direction can be continuous.
[0020] Furthermore, even smoother surfaces can be achieved if the pitch of the neck's profile along the longitudinal axis and / or circumferential direction is continuous. Specifically, the neck's profile along the longitudinal axis and / or circumferential direction can be continuous in curvature and gradient. This creates a smooth and easy-to-clean surface.
[0021] In other words, the neck can have a continuous outer periphery extension in most of the cross-sections perpendicular to the longitudinal axis, and especially in all of them. Furthermore, the outer periphery of the neck in these cross-sections can be formed by non-concentric segments.
[0022] Similarly, to facilitate easier cleaning of the inner circumferential surface of the cap's channel, the channel's profile along the longitudinal axis and / or circumferential direction can be continuous. Furthermore, for the reasons mentioned above, the pitch of the channel's profile along the longitudinal axis and / or circumferential direction can be continuous. In particular, the channel's profile along the longitudinal axis and / or circumferential direction can be continuous in curvature and gradient.
[0023] Furthermore, the inner profile of the channel can be continuous in most of the cross-sectional planes perpendicular to the longitudinal axis, and particularly in all of its cross-sectional planes perpendicular to the longitudinal axis. The inner profile of the channel in these cross-sectional planes can be formed by non-concentric segments.
[0024] According to one embodiment, the non-circular inner contour of the cap's opening and / or the non-circular outer contour of the neck are selected from the group of shape members consisting of oval, elliptical, hyperbolic, and hyperbolic triangles (i.e., triangles with rounded edges). Generally, the non-circular contours are preferably symmetrical and / or do not form any sharp edges.
[0025] According to another embodiment, in a plane transverse to the longitudinal axis of the container, the width-to-height ratio of the inner contour of the non-circular shape of the opening is selected within the range of 80-95%, depending on the diameter of the container. In other words, the minimum diameter of the contour is between 0.8 and 0.95 times the length of the longest diameter of the contour.
[0026] According to one embodiment, when the cap is attached to the neck, the inner contour of the cap and the outer contour of the neck form a clearance fit. Specifically, the inner contour of the cap is 0.5% to 2.0% larger than the outer contour of the neck. In other words, each inner diameter of the channel is 0.5% to 2.0% larger than the corresponding outer diameter of the neck.
[0027] According to one embodiment, one or more seals are arranged between the neck and the cap to seal between the neck and the cap when the cap is installed in the reservoir. The seal is preferably arranged between the inner surface of the neck and the cap, particularly the internal support structure of the cap.
[0028] In order to apply the contents of the reservoir, such as a cosmetic product, more precisely, the applicator can be positioned at the cap. In this case, a seal can be positioned between the inner surface of the neck and the support structure for the applicator.
[0029] According to one embodiment, the container further includes a securing device configured to provide at least one of an audible click and a perceptible resistance when the cap is fully attached to the neck. The securing device may include a wavy surface, particularly multiple peaks separated by multiple valleys. Alternatively or additionally, the securing device may include one or more domed protrusions. The securing device may be formed on the inner circumferential surface of the channel and the outer circumferential surface of the neck. The securing device may disrupt the overall continuity of the inner and outer circumferential surfaces, as long as they do not interfere with the attachability of the cap to the neck.
[0030] The reservoir may contain a material stored therein, wherein the material is a liquid, paste, or pourable solid material. In particular, the material may be selected from the group consisting of: beauty products, cosmetic products, cleaning products, skin care products, medical products, dental products, pharmaceutical products, adhesives, paints, and building materials. In other words, the reservoir is configured to contain at least one of the materials. Attached Figure Description

[0051] Figure 1 A container 10 with a reservoir 12 and a cap 14 is depicted. The cap 14 is repeatedly attached to the reservoir 12 to close the container 10. For attaching the cap 14 to the reservoir 12, the cap 14 has a channel 16 extending along the longitudinal axis A of the container 10, the channel 16 having an opening 16a in one of its end regions. In other words, the cap 14 has a blind hole formed therein. The reservoir 12 has a neck 18 configured to be inserted into the channel 16 via the opening 16a.
[0052] For example, through comparison Figure 3A and Figure 3B As can be seen in the cross-sectional view, channel 16 has an inner circumferential shape along the longitudinal axis, namely an inner profile 20, which is non-circular for at least a majority of the length of channel 16, wherein the majority length is at least 51%, preferably at least 80%, of the length of channel 16. This non-circular inner profile 20 varies along the longitudinal axis such that points equidistant from the longitudinal axis on the profile form a spiral 21. In other words, channel 16 has an inner circumferential surface that is formed as the inner circumferential surface of a twisted, non-circular tube.
[0053] Therefore, the neck 18 has a non-circular outer circumferential shape along the longitudinal axis, namely the outer contour 22. The outer contour 22 is complementary to the inner contour 20 so that the cap 14 can be attached to the neck 18 by rotating the cap 14 relative to the reservoir 12.
[0054] The non-circular outer contour 22 varies along the longitudinal axis, causing points equidistant from the longitudinal axis A on this contour to form a spiral 23 (see...). Figure 5B The spiral 23 has the same pitch or gradient as the spiral 21 formed by the inner contour 20. In other words, the neck 18 has an outer circumferential surface that is formed as the outer circumferential surface of a twisted, non-circular element.
[0055] As from Figure 2 and Figure 3A As can be seen, the outer contour 22 of the neck 18 has a convex outer surface 22a, and the inner contour 20 of the cap 14 in a fully attached state forms a corresponding concave surface 20a. Conversely, as in... Figure 3B As can be seen in the second cross-sectional view, the outer contour 22 of the neck 18 has a concave outer surface 22b, and the inner contour 20 of the cap 14 in a fully attached state forms a corresponding convex surface 20b.
[0056] The outer contour 22 of the neck 18 includes a surface comprising both a convex outer surface 22a and a concave outer surface 22b, wherein the relative positions of the different shapes of the outer contour 22 vary radially and axially relative to the longitudinal axis A to form a mating surface 22c that interacts with the inner contour 20 of the cap 14 for attaching the cap 14. The inner contour 20 has correspondingly shaped opposing mating surfaces 20c.
[0057] The outer contour 22 of the neck 18 and the corresponding inner contour 20 of the cap 14 allow the cap 14 to be attached to the neck 18, thereby forming a form-fit engagement in the axial direction without the presence of conventional threads.
[0058] Next, refer to Figure 4A and 4B This explains how a press-fit engagement occurs after the cap 14 is fully attached to the neck 18. When the cap 14 is fully attached to the neck 18, the outer circumferential surface of the neck 18 and the inner circumferential surface of the cap 14 face each other at a constant distance (see [link to documentation]). Figure 4ASpecifically, since the outer perimeter of the neck 18 and the inner perimeter of the cap 14 are non-circular, in this example they are oval, so the maximum outer diameter of the neck 18 matches the maximum inner diameter of the cap 14 in its angular orientation, and the minimum outer diameter of the neck 18 matches the minimum inner diameter of the cap 14 in its angular orientation. When the cap 14 is subsequently rotated further relative to the neck 18, the maximum outer diameter of the neck 18 is positioned at an angular location where the inner diameter of the cap 14 is smaller than the maximum outer diameter of the neck 18 (see...). Figure 4B Therefore, the cap 14 and the neck 18 form a press fit, wherein the force caused by the press fit is oriented approximately in the radial direction.
[0059] Figure 5A and 5B The outer contour 22 of the neck 18, i.e. the form of the mating surface 22c, is depicted. Figure 5A The diagram illustrates how the outer contour 22 would look if it were made from different oval rings 24 of varying thicknesses. A first oval ring 24A would be placed at the bottom. Next, a second identical oval ring 24B would be placed on top of the first oval ring 24A, but at an angular offset relative to the longitudinal axis A. The next oval ring 24C would be placed on top of the oval ring 24B at the same angular offset relative to the longitudinal axis A, and so on.
[0060] In order to form a continuous outer surface of the neck 18, as in Figure 5B As can be seen, the actual outer contour can thus be described as an oval ring 24 with infinitesimal thickness positioned on top of each other at a constant angular offset relative to the longitudinal axis A and to the corresponding oval rings 24 placed earlier and later. In other words, the outer contour 22 of the neck can be described as the angular position of each oval contour being controlled by a spiral 23 arranged along the longitudinal axis A of the neck 18.
[0061] Alternatively, the continuous outer surface of the neck 18 may be functionally described as an ellipsoid 22 controlled by a spiral 23 extending in the longitudinal direction A.
[0062] It should be noted that the overall shape of ring 24, and therefore profile 22, need not be oval, but may have other shapes. This results in a continuous outer surface in which points equidistant from the longitudinal axis A form a spiral 23.
[0063] The inner contour 20 of the cap 14 is formed by correspondingly shaped rings, which have an inner surface that is complementary to the outer shape of the neck 18, which is depicted by an oval ring 24.
[0064] Figures 6A to 8The structure for forming the fastening device 26 is shown, which interrupts the continuity of the outer circumferential surface of the neck 18. The fastening device 26 is formed by a plurality of parallel valleys or grooves 26a arranged at least substantially parallel to each other or parallel to each other on the inner circumferential surface of the cap 14 and a plurality of correspondingly formed ridges or peaks 26b on the outer circumferential surface of the neck 18.
[0065] The fastening device 26 is configured to provide a plurality of defined locking positions for the cap 14 relative to the neck 18, wherein each locking position provides an audible click and a perceptible resistance when the cap 14 is rotated into the locking position after it is fully attached to the neck 18.
[0066] It should be noted that only one valley or groove 26a may be provided at the inner contour 20 of the cap 14, and only one corresponding ridge or peak 26b may be formed on the outer peripheral surface of the neck 18.
[0067] In this regard, it should be noted that the fixing device 26 may include one or more valleys or troughs 26a, which are arranged at least substantially parallel to each other or parallel to each other on the inner circumferential surface of the cap 14.
[0068] It should also be noted that the fixing device 26 may include one or more ridges or peaks 26b, which are arranged at least substantially parallel to each other or parallel to each other on the outer peripheral surface of the neck 18.
[0069] It should also be noted that the fixing device 26 may be arranged at least substantially parallel to at least one of the corresponding spirals 21, 23.
[0070] exist Figure 12A An embodiment of the fastening device 26' is shown, which includes a groove or ridge extending along a portion of the neck along a helix. At least one corresponding ridge or groove is present on the inner circumferential surface of the cap 14 to form a shape-fit engagement between the cap 14 and the neck 18.
[0071] Similarly, Figure 12B Another embodiment of the fastening device 26” is shown. In this embodiment, the fastening device includes a domed protrusion 26” or a recess. Furthermore, the fastening device 26” includes a corresponding recess or domed protrusion on the inner circumferential surface of the cap 14. The domed protrusion 26” can engage with the corresponding recess to form a form-fit engagement, thereby securing the cap 14 to the neck 18.
[0072] exist Figures 8 to 9B The first embodiment of the neck 18 is shown in the figure. Figure 9AThe outer circumferential surface or outer contour 22, which is best visible from within, has an oval cross-sectional shape. The minimum diameter of this oval shape is 12.5 mm, while the maximum diameter is 13.5 mm. The measurement results may vary depending on the size of the container 10.
[0073] Generally, the ratio between the minimum diameter and the maximum diameter of the oval shape is selected in the range of 0.9 to 0.96, particularly 0.91 to 0.95, and especially 0.92 to 0.94. In particular, the ratio between the minimum diameter and the maximum diameter of the oval shape can be 0.926.
[0074] The neck 18 also has an inner circumferential surface 28, which defines an inner cross-sectional shape that is circular. The inner circumferential surface 28 defines a channel 30 that leads to a volume 32 defined by the reservoir 12. Figure 9B ( ), to store products, such as beauty products.
[0075] exist Figures 10 to 11B The second embodiment of the neck 18 is shown in the figure. Figure 11A The outer peripheral surface, which is best viewed from the center, has a cross-sectional shape that is consistent with... Figures 8 to 9B Similar to the embodiment shown, the cross-sectional shape is axisymmetric, but... Figures 8 to 9B In contrast to the embodiment shown, the cross-sectional shape has three maximum outer diameters 34. In particular, the neck 18 shown has a cross-sectional shape in the form of a hyperbolic trigon. This embodiment has the advantage that the cap 14 can be placed on the neck 18 at three different angular positions, each 120° apart from the other, making it easier to attach the cap 14 to the neck 18.
[0076] As in Figure 3A and Figure 3B As can be seen, the cap 14 also includes a support structure 36 for an applicator (not shown). This support structure 36 extends along the longitudinal axis A of the cap 14 and is partially surrounded by the inner circumferential surface of the cap. A seal 38 is located at the inner circumferential surface 28 of the neck 18. This seal 38 is configured to seal against the support structure 36 when the cap 14 is attached to the neck 18 of the reservoir 12.
[0077] When the cap 14 is attached to the neck 18, the convex portion of the mating surface 22c engages the concave portion of the opposing mating surface 20c, and similarly, the concave portion of the mating surface 22c engages the convex portion of the opposing mating surface 20c. The cap is attached to the neck 18 of the reservoir 12 by rotating the cap 14 relative to the neck 18. When the cap 14 is rotated relative to the reservoir 12, it engages the neck 18 not only with a form-fit engagement but also with a press-fit engagement in the radial direction between the inner circumferential surface of the channel 16 and the outer circumferential surface of the neck 18, thus securing the cap 14 to the reservoir 12. Using common threads would only produce a form-fit engagement in the radial direction, but not such a press-fit.
