Description

[0001] The invention relates to a vessel comprising a container and a cap, wherein the cap can be repeatedly attached to the container to close the vessel.

[0002] Such containers are used for many applications, including the packaging of beauty products such as mascara. Several systems are known for attaching the cap to the container, including profiled threads, a bayonet lock, a swivel cap combined with a snap closure, a wire clip closure, an eccentric grip for compressing a seal, or a bistable snap-on lid.

[0003] The above-mentioned systems are complex in shape, difficult to manufacture, or require multiple parts. There is a need for a container that allows for simple, quick, and reliable attachment of the cap to the container.

[0004] This need is met by a vessel according to claim 1 and in particular by a vessel comprising a container and a cap, wherein the cap can be repeatedly attached to the container for closing the vessel, the cap has a passage with an opening formed therein, the container has a neck for insertion into the passage via the opening of the cap along a longitudinal axis of the vessel, wherein the opening of the cap has a non-circular inner contour that is complementary to a non-circular outer contour of the neck, wherein an inner peripheral surface of the passage and an outer peripheral surface of the neck are shaped such that a positive engagement in the axial direction can be produced by rotating the cap relative to the container about the longitudinal axis, and wherein the inner peripheral surface of the passage and the outer peripheral surface of the neck are shaped such thatthat a press-fit engagement in the radial direction between the inner peripheral surface of the passage and the outer peripheral surface of the neck can be created by rotating the cap relative to the container about the longitudinal axis after the cap is in positive engagement with the neck.

[0005] The invention is based on the idea that the cap and the container are fastened to one another by first creating a positive engagement in the axial direction - e.g. similar to a thread - and then a press-fit engagement which - unlike a thread - is created in the radial direction between the inner peripheral surface of the passage and the outer peripheral surface of the neck by rotating a non-circular portion of the passage in the cap relative to a non-circular portion of the neck of the container.

[0006] Embodiments of the vessel are defined in the dependent claims and described in the following disclosure.

[0007] The non-circular inner contour of the cap may extend along a portion of the passage or substantially along the entire passage. Accordingly, the non-circular outer contour of the neck may extend along a portion of the neck or substantially along the entire neck.

[0008] According to one embodiment, the outer peripheral surface of the neck is formed as the outer peripheral surface of a twisted, non-circular element; and the inner peripheral surface of the passage is correspondingly formed as the inner peripheral surface of a twisted, non-circular tube, in particular a twisted, non-cylindrically shaped tube twisted such that portions of this tube are non-circular in a plane perpendicular to the longitudinal axis, so that the cap can be attached to the neck of the container. In other words, the neck has non-circular cross-sections with constant sizes along the longitudinal axis, but the orientation of the non-circular cross-sections constantly changes, so that points on the surface evenly spaced from the longitudinal axis of the neck are arranged along a spiral.

[0009] According to a second aspect, a vessel is provided comprising a container and a cap, the cap being repeatedly attachable to the container for closing the container, the cap having a passage with an opening formed therein, the container having a neck for insertion into the passage via the opening of the cap along a longitudinal axis of the vessel, the opening of the cap having a non-circularly shaped inner contour complementary to a non-circularly shaped outer contour of the neck, an outer peripheral surface of the neck being formed as an outer peripheral surface of a twisted non-circular element; and an inner peripheral surface of the passage being correspondingly formed as an inner peripheral surface of a twisted non-circular tube, such that the cap can be attached to the neck of the container by rotating the cap relative to the container.

[0010] According to one embodiment, the non-circular contour of the neck and / or the passage has a symmetrical circumferential shape. The circumferential shape can be mirror-symmetrical, e.g., oval. This allows the cap to be placed on the neck in two different angular positions. Alternatively, the circumferential shape can be rotationally symmetrical, e.g., in the shape of a hyperbolic polygon, e.g., a trigon. This simplifies the attachment of the cap to the neck, as it is possible to place the cap on the neck in, for example, three different angular positions.

[0011] According to a further embodiment, the inner peripheral surface of the passage and the outer peripheral surface of the neck are shaped and / or configured such that rotation of the cap relative to the container about the longitudinal axis forces the cap toward the container along the longitudinal axis. This allows the cap to be easily placed onto the neck of the container.

[0012] To create a radial interference fit between the container neck and the cap, the inner peripheral surface of the passage may have a plurality of concave surfaces, and the outer peripheral surface of the neck may have corresponding convex peripheral surfaces. These allow the cap to be clamped onto the neck by rotating the cap relative to the container neck. In particular, this should only be possible during regular operation when the cap is fully seated on the container neck.

[0013] In order to be able to put the cap on and remove it from the container relatively quickly, the outer peripheral surface of the neck can be designed as the outer peripheral surface of a non-circular element twisted by 360° or less and the inner peripheral surface of the passage can be designed as the inner peripheral surface of a non-circular tube twisted by 360° or less.

[0014] To provide a quick-release function, i.e., to enable the cap to be quickly attached to and removed from the container, the outer peripheral surface of the neck may be configured as the outer peripheral surface of a non-circular member rotated by 180°, and the inner peripheral surface of the passage may be configured as the inner peripheral surface of a non-circular tube rotated by 180°. In this way, the cap can be fully fitted onto the neck of the container by rotating the cap relative to the neck by approximately half a turn. The interference fit can be achieved by rotating the cap 5° to 20° relative to the neck after it has been fully fitted onto the neck.

[0015] In order to obtain a smooth outer surface of the neck that is easy to clean, the contour of the neck may be continuous along the longitudinal axis and / or the circumferential direction.

[0016] Furthermore, an even smoother surface can be achieved if the neck contour has a continuous gradient along the longitudinal axis and / or the circumferential direction. In particular, the neck contour can have a continuous curvature and gradient along the longitudinal axis and / or the circumferential direction. This creates a smooth and easy-to-clean surface.

[0017] In other words, the neck can have a continuous outer circumferential extension in a plurality of sectional planes perpendicular to the longitudinal axis, in particular in all sectional planes. Furthermore, the outer circumference of the neck can be formed by non-concentric sections in these sectional planes.

[0018] Likewise, to facilitate cleaning of the inner circumferential surface of the passage of the cap, the contour of the passage can be continuous along the longitudinal axis and / or the circumferential direction. Furthermore, for the reasons stated above, the gradient of the contour of the passage can be continuous along the longitudinal axis and / or the circumferential direction. In particular, the contour of the passage can be continuous in curvature and gradient along the longitudinal axis and / or the circumferential direction.

[0019] Furthermore, the inner contour of the passage can be continuous in a plurality of sectional planes perpendicular to the longitudinal axis, in particular in all sectional planes perpendicular to the longitudinal axis. The inner contour of the passage can be formed by non-concentric sections in these sectional planes.

[0020] According to one embodiment, the non-circular inner contour of the cap opening and / or the non-circular outer contour of the neck is selected from the group of shape elements consisting of an oval shape, an elliptical shape, a hyperbolic shape, and a hyperbolic trigon, i.e., a triangle with rounded edges. In general, the non-circular contour is preferably symmetrical and / or has no sharp edges.

[0021] According to a further embodiment, the ratio of the width to the height of the non-circular inner contour of the opening in a plane transverse to the longitudinal axis of the vessel is in the range of 80-95%, depending on the diameter of the vessel. In other words, the smallest diameter of the contour is between 0.8 and 0.95 times the longest diameter of the contour.

[0022] According to one embodiment, the inner contour of the cap and the outer contour of the neck form a clearance fit when the cap is placed on the neck. 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 passage is 0.5% to 2.0% larger than the respective outer diameter of the neck.

[0023] 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 on the container. The seal is preferably arranged between an inner surface of the neck and the cap, in particular an inner support structure of the cap. To enable more targeted application of the contents of the container, e.g., a beauty product, an applicator can be arranged on the cap. In this case, the seal can be arranged between an inner surface of the neck and a support structure for the applicator.

[0024] According to one embodiment, the vessel further comprises a securing device configured to produce at least an audible click or a tactile resistance when the cap is fully installed on the neck. This securing device may comprise a corrugated surface, in particular a plurality of protrusions separated by a plurality of depressions. Alternatively or additionally, the securing device may comprise one or more domes. The securing device may be formed on the inner peripheral surface of the passageway and the outer peripheral surface of the neck. The securing device may disrupt the general continuity of the inner and outer peripheral surfaces as long as it does not interfere with the ability of the cap to be attached to the neck.

[0025] The container can hold a material, which can be a liquid, a paste, or a pourable solid. The material can be selected, in particular, from the group of the following products: beauty products, cosmetic products, cleaning products, skin care products, medical products, dental products, pharmaceutical products, adhesives, paints, and building materials. In other words, the container is configured to accommodate at least one of the aforementioned materials.

[0027] In Fig. 1 shows a vessel 10 with a container 12 and a cap 14. The cap 14 can be repeatedly placed onto the container 12 to close the vessel 10. To secure the cap 14 to the container 12, the cap 14 has a passage 16 extending along a longitudinal axis A of the vessel 10 and having an opening 16a in one of its end regions. In other words, a blind hole is formed in the cap 14. The container 12 has a neck 18 designed to be inserted into the passage 16 via the opening 16a.

[0028] As can be seen from the comparison of the sectional views of the Fig. 3A and Fig. 3B, the passage 16 has an inner circumferential shape along the longitudinal axis, i.e., an inner contour 20 that is non-circular over at least a majority of the length of the passage 16, the majority of the length being at least 51%, preferably at least 80% of the length of the passage 16. The non-circular inner contour varies along the longitudinal axis such that points of the contour equidistant from the longitudinal axis form a spiral 21. In other words, the passage 16 has an inner circumferential surface configured as the inner circumferential surface of a twisted, non-circular tube.

[0029] Accordingly, the neck 18 has an outer peripheral shape along the longitudinal axis, i.e., an outer contour 22 that is not circular. The outer contour 22 is shaped complementarily 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 container 12.

[0030] The non-circular outer contour 22 varies along the longitudinal axis, so that points of the contour that are equidistant from the longitudinal axis A form a spiral 23 (see Fig. 5B) which has the same pitch or inclination as the spiral 21 formed by the inner contour 20. In other words, the neck 18 has an outer peripheral surface which is formed as the outer peripheral surface of a twisted, non-circular element.

[0031] As can be seen from the Fig. 2 and Fig. 3A, the outer contour 22 of the neck 18 has a convex outer surface 22a, and the inner contour 20 of the cap 14 forms a corresponding concave surface 20a in the fully fastened state. In contrast, as shown in Fig. 3B in a second 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 forms a corresponding convex surface 20b in a fully fastened state.

[0032] The outer contour 22 of the neck 18 comprises a surface including both the convex outer surface 22a and the concave outer surface 22b, wherein a relative position of the various shapes of the outer contour 22 varies both radially and axially relative to the longitudinal axis A to form an engagement surface 22c that cooperates with the inner contour 20 of the cap 14 to secure the cap 14. The inner contour 20 has a correspondingly shaped counter-engagement surface 20c.

[0033] The outer contour 22 of the neck 18 and the corresponding inner contour 20 of the cap 14 make it possible to fasten the cap 14 to the neck 18, creating a positive engagement in the axial direction without the need for a conventional thread.

[0034] The following is based on Fig. 4A and Fig. Figure 4B explains how a press-fit engagement is created after the cap 14 is fully secured to the neck 18. When the cap 14 is fully secured to the neck 18, the outer peripheral surface of the neck 18 and the inner peripheral surface of the cap 14 are opposite each other at a constant distance (see Fig. 4A). Since the outer circumference of the neck 18 and the inner circumference of the cap 14 are not circular, but oval in this example, the largest outer diameter of the neck 18 corresponds to the largest inner diameter of the cap 14 in terms of its angular orientation, and the smallest outer diameter of the neck 18 corresponds to the smallest inner diameter of the cap 14 in terms of its angular orientation. If the cap 14 is then further rotated relative to the neck 18, the largest outer diameter of the neck 18 is brought into an angular position in which the inner diameter of the cap 14 is smaller than the largest outer diameter of the neck 18 (see Fig. 4B). Therefore, the cap 14 and the neck 18 form an interference fit engagement, with the force caused by the interference fit engagement being generally directed in a radial direction.

[0035] In the Fig. 5A and Fig. 5B shows how the outer contour 22, ie the shape of the engagement surface 22c, of the neck 18 is formed. Fig. Figure 5A shows what the outer contour 22 would look like if it were made from various oval rings 24 of a specific thickness. A first oval ring 24A would be placed on the ground. Next, a second, identical oval ring 24B would be placed on the first oval ring 24A, but with an angular offset relative to the longitudinal axis A. The next oval ring 24C is placed on the oval ring 24B with the same angular offset relative to the longitudinal axis A, and so on.

[0036] In order to create a continuous outer surface of the neck 18, as in Fig. 5B, the actual outer contour can be described by superimposing oval rings 24 with an infinitesimally small thickness with a constant angular offset relative to the longitudinal axis A and the respective oval ring 24 placed before and after. In other words, the outer contour 22 of the neck can be described such that an angular position of each of the oval contours is controlled by a spiral 23 arranged along the longitudinal axis A of the neck 18.

[0037] Alternatively, the continuous outer surface of the neck 18 can be functionally described as an ellipsoid 22 controlled by a spiral 23 extending in the longitudinal direction A.

[0038] It should be noted that the general shape of the rings 24, and thus of the contour 22, does not have to be oval, but can also have other shapes. This results in a continuous outer surface whose points are equidistant from the longitudinal axis A and which form the spiral 23.

[0039] The inner contour 20 of the cap 14 is formed by correspondingly shaped rings, the inner surface of which is complementary to the outer shape of the neck 18, represented by the oval rings 24.

[0040] The Fig. 6A to 8 show a structure for forming a securing device 26 that interrupts the continuity of the outer peripheral surface of the neck 18. The securing device 26 is formed by a plurality of parallel, at least substantially parallel or parallel to each other, valleys or grooves 26a formed on the inner peripheral surface of the cap 14, and a plurality of correspondingly shaped elevations or ridges 26b formed on the outer peripheral surface of the neck 18.

[0041] The locking device 26 is configured to provide a plurality of defined locking positions for the cap 14 relative to the neck 18, each locking position producing an audible click and a tactile resistance when the cap is rotated into the locking position after the cap 14 is fully secured to the neck 18.

[0042] It should be noted that only one valley or groove 26a could be provided on the inner contour 20 of the cap 14, with only one correspondingly shaped elevation or peak 26b being formed on the outer peripheral surface of the neck 18.

[0043] In this context, it should be noted that the securing device 26 may have one or more recesses or grooves 26a arranged at least substantially parallel to one another or parallel to one another on the inner peripheral surface of the cap 14.

[0044] It should further be noted that the securing device 26 may include one or more ridges or peaks 26b arranged at least substantially parallel to one another or parallel to one another on the outer peripheral surface of the neck 18.

[0045] It should further be noted that the securing device 26 may be arranged at least substantially parallel to at least one of the respective spirals 21, 23.

[0046] In Fig. 12A illustrates an embodiment of the securing device 26' that includes a groove or protrusion extending along a majority of the neck in a spiral fashion. At least one corresponding protrusion or groove is located on the inner peripheral surface of the cap 14, forming a positive engagement between the cap 14 and the neck 18.

[0047] Similarly, Fig. 12B illustrates another embodiment of the securing device 26". In this embodiment, the securing device includes a dome 26" or recess. Further, the securing device 26" includes a corresponding recess or dome on the inner peripheral surface of the cap 14. The dome 26" is engageable with the corresponding recess to form a positive engagement for securing the cap 14 to the neck 18.

[0048] In the Fig. 8 to 9B, a first embodiment of the neck 18 is shown. As in Fig. As best seen in Figure 9A, the outer peripheral surface or outer contour 22 has an oval cross-sectional shape. While the smallest diameter of the oval shape is 12.5 mm, the largest diameter of the oval shape is 13.5 mm. The dimensions may vary depending on the size of the vessel 10.

[0049] Generally, the ratio between the smallest diameter of the oval shape and the largest diameter of the oval shape is chosen in the range of 0.9 to 0.96, especially 0.91 to 0.95, and especially 0.92 to 0.94. In particular, the ratio between the smallest diameter of the oval shape and the largest diameter of the oval shape can be 0.926.

[0050] The neck 18 also has an inner peripheral surface 28 defining an inner cross-sectional shape that is circular. The inner peripheral surface 28 defines a passage 30 leading to a volume 32 ( Fig. 9B) defined by the container 12 for storing a product, e.g. a beauty product.

[0051] In the Fig. 10 to 11 B, a second embodiment of the neck 18 is shown. As in Fig. 11A, the outer peripheral surface has a cross-sectional shape which, as in the case of the Fig. 8 to 9B - is axially symmetric, but - in contrast to the embodiment shown in the Fig. 8 to 9B—has three largest outer diameters 34. In particular, the illustrated neck 18 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 in three different angular positions, each 120° apart, which facilitates the attachment of the cap 14 to the neck 18.

[0052] As in the Fig. 3A and Fig.As can be seen in Figure 3B, the cap 14 further includes a support structure 36 for an applicator (not shown). The support structure 36 extends along the longitudinal axis A of the cap 14 and is partially enclosed by the inner peripheral surface of the cap. A seal 38 is located on the inner peripheral surface 28 of the neck 18. The seal 38 is configured to seal against the support structure 36 when the cap 14 is attached to the neck 18 of the container 12.

[0053] When the cap 14 is attached to the neck 18, the convex-shaped portion of the engagement surface 22c engages the concave-shaped portion of the mating engagement surface 20c, and the concave-shaped portion of the engagement surface 22c engages the convex-shaped portion of the mating engagement surface 20c, and by rotating the cap 14 relative to the neck 18, the cap is attached to the neck 18 of the container 12. Upon rotating the cap 14 relative to the container 12, the cap not only positively engages the neck 18, but also forms a radial interference fit between the inner peripheral surface of the passage 16 and the outer peripheral surface of the neck 18 to secure the cap 14 to the container 12. The use of a conventional thread would only result in a positive engagement in the radial direction, but not such an interference fit.
