Description

The invention relates to a container according to the features of the preamble of claim 1.

Such containers have already become known in many ways. For example, as cosmetic containers, in which a cosmetic composition is added. A user usually holds the container base in his hand and turns the container lid off or unscrews it.

From the JP 6-81954 U a container with a lid is known, which are screwed together. However, the screw is only possible until the projection of a thread rib on the container engages in a gap of a thread rib of the container lid or vice versa. Next is the state of the art on the JP-H11-152155 A . US 1,773,947 A . BE 348952 A . US 5,913,434 A and US 1,947,382 A to refer.

There is a need to form such a container with an advantageously operable closure. On this basis, the object of the invention is to specify a container with an advantageous closure.

This object is achieved in the subject matter of claim 1, wherein it is pointed out that each formed on the container lid and the BehälterUnterteil thread ribs are formed over a circumferential angle of 90 degrees or less, in the circumferential direction of the lid and the lower part at least one circumferential extent leave corresponding distance (circumferential angle β) and formed on the cover and the lower part at least two thread ribs in the circumferential counter-overlay, said further in a given in the course of a screw superimposed in Direction of the screw axis of rotation of a threaded rib of the base and a threaded rib of the lid in only one of the two superpositions complete overflow in the circumferential direction is possible and the thread ribs of the lid and the thread ribs of the lower part are vertically spaced so far from each other that they are in the circumferential angular orientation in which the screw end position is not reached, with respect to a circumferential band, which they each take in the circumferential direction of their given in the direction of the screw rotation axis extension taking into account a slope, are separated from each other.

The configuration makes it possible to twist the container lid and the container bottom to the final closure, when the parts in view of the corresponding spaces in the circumferential direction of the thread ribs in superimposition and offset in the direction of the screw axis of rotation in abutment against each other only slightly against each other. After such (only) vertical movement of the container base and the container lid in mutual contact, only a movement in the circumferential direction of the parts is to perform relative to each other, so it is no longer necessary that the parts are like a usual closing screwing (then) also move towards each other in the direction of the screw rotation axis. In this case, a defined position in Verschraubzustand between the container lid and the container base is reached because only in one of the two opposites, ie only in a defined circumferential angle position the screw is given. In the other of the two Zusammenwirkungslagen in the circumferential direction will overflow occur when screwing.

The vertically spaced the thread ribs of the lid or the lower part so that they in the circumferential angular orientation, in which the screw end position is not reached, with respect to a circumferential band, the they each take in the circumferential direction of their given in the direction of the screw rotation axis extension taking into account a slope, are separated from each other, undercutting is possible in one of the circumferential positions. But it can also take a certain increase by placing or driving on a thread rib, in the course of the rotational movement of the parts to each other when the parts are seen in such a circumferential angle of the final closure position (only) brought into superposition and then the rotational movement to achieve the closure position is carried out that in this case the thread ribs of the container lid and container base are still in superimposition or even come in the course of the rotational movement, if necessary.

Threaded ribs formed on the container lid and the container bottom may be formed over a circumferential angle of 20 ° or less. Only two threaded ribs can be formed on the container lid and on the container lower part in each case. The thread ribs of the container lid or of the container lower part are per se spaced in the direction of the screw rotation axis and can be arranged so that they do not overlap each other in this direction.

The fact that only two respective thread ribs are formed on the container lid and on the container lower part, which are spaced apart in the circumferential direction so that they extend to each other without overlap, also include a circumferential angle of less than 90 °, is a very quick rotational attachment between the Container lid and the container bottom possible. In addition, for such a container, in particular when it comes to a cosmetics container, given in the open position a favorable appearance, since the only two thread ribs, in particular the thread ribs of the container base, the most in the open state eye-catching, leaving a little technical impression. They can also be understood as decorative ribs.

It is preferred that in each case one of the thread ribs is associated with a stop section extending in the direction of the screw rotation axis. Of the Stop section can be formed directly on the thread rib. It extends apparently substantially at right angles or taking into account the pitch of the threaded rib at an obtuse angle to the threaded rib, which is associated with each. With regard to the obtuse angle, the direction in which the abutment section extends with respect to the screw rotation axis is therefore also given.

The abutment portion can also be formed with an interruption to the threaded rib, - seen in the direction of the screw-axis of rotation. It is essential in any case that the abutment portion is formed in the direction of the screw axis of rotation to a bottom of the container base towards or to a ceiling of the container lid as close to the threaded rib, to which it is assigned, that the counter-threading rib of the retracting in the circumferential direction Container lid or the container base thereby in the retraction direction when it comes to the abutment portion comes to rest, is blocked. The stop sections also allow a very precise end position in Zuschraubrichtung. Although a stop section is essentially a same end position, for example by a clamping retraction between the respective thread rib and a subpart side or cover side perpendicular to the screw axis of rotation extending, no longer belonging to the thread area or by bracing using a retraction stop, if necessary given by a lower end face of a peripheral wall of the one part, which then abuts a corresponding step of the other part, possible, but not in the high degree of highly precise provision of an end position, as is possible with a said stopper portion.

In a further detail, the container lid has a first circumferential wall extending in the direction of the screw axis of rotation and a ceiling or a delimiting section extending transversely thereto, which also extends in a rib which projects only radially inwards or radially outwards or in such a way Paragraph, possibly circumferentially only partially formed, may consist of, wherein on an inner side of the first peripheral wall, the thread ribs are formed and wherein further at least one of the thread ribs facing away from the ceiling free end edge of the first peripheral wall is assigned, while in any case other thread rib of the Ceiling is assigned. Preferably, the thread ribs of the respective part of the container lid or of the container lower part are formed as far as possible from each other in the direction of the screw axis of rotation. The actual distance dimension also depends on the extent to which the first peripheral wall and the second circumferential wall described below in the closed position in the direction of the screw rotation axis are in register with each other. In any case, it is preferred that the spacing of thread ribs of the respective same part in the direction of the screw rotation axis is greater than a width of a thread rib in this direction.

On the container lower part is further preferably a extending in the direction of the screw axis of rotation second peripheral wall and extending transversely thereto container bottom is formed, wherein on an outer side of the second peripheral wall, the thread ribs of the container bottom are formed, and further wherein one of the thread ribs of the container bottom of a Floor facing away from the free edge edge of the second peripheral wall is assigned, while at least one further thread rib of the container base is formed on the bottom side of the second peripheral wall.

The mentioned assignment means, in particular, that there is a small vertical distance between the thread rib and the associated lid or the free end edge. This vertical distance is preferably given in the range of a thickness of a thread. In particular, it is preferred that the distance in any case corresponds to a thickness of a thread.

It can also be larger, about 1.1 to 2 times or more, up to, for example, 3 times the thickness of a thread correspond.

This embodiment of the first and the second peripheral wall described here means that in screw assignment the first peripheral wall is outside and the second peripheral wall is inside. It is also the reverse design possible that in Schraubzuordnung the first peripheral wall inside and the second peripheral wall is outside. In such a case, then, the thread ribs on the container lid are formed on the outside of the first peripheral wall and on the container bottom part the thread ribs are formed on the inside of the second circumferential wall.

With respect to the first or peripheral wall, a circular cross-section is also given for the implementation of the screw. By contrast, with regard to the container bottom and the container ceiling is not necessary, even if this is preferred, given a circular floor plan. Due to the preferably possible unique circumferential angular orientation with respect to the screw threaded connection with each other coextensive circumferential walls rather such a geometric design of the container ceiling or the container bottom in terms of their floor plans is possible only in this selected peripheral angular position, based on the peripheral walls , leads to an aligned superimposition in the closed position.

With regard to the stopper portions, it is preferable that one of the stopper portions is formed on the thread cap of the container lid associated with the container lid, and / or that a stopper portion or the further stopper portion is formed on the thread rib provided on the bottom side of the second peripheral wall of the container base.

The circumferential extent of the mentioned thread ribs is preferably also significantly smaller than 90 °. The circumferential extent can be formed down to, for example, only 5 to 10 °. Preferably, a circumferential extent of a thread rib is approximately in the range of 30 to 70 °.

In particular, because of the preferably small circumferential angle formation of a thread rib, a large circumferential region, on which no thread rib is formed, is evident on the first or second circumferential wall. On the other hand, in the closed state of the container, this may cause the container lid or a corresponding area of the peripheral wall of the container lid to be slightly radially inwardly compressible to a certain extent, and conversely, this may also result if, as noted alternatively, the peripheral wall of the container lower part in the closed state is outside, this peripheral wall of the container base can then be pressed slightly radially inward.

To remedy this situation, it is provided in a further preferred embodiment that on the second peripheral wall in a circumferential gap between the thread ribs a radially projecting to the extent of a thread support portion is formed. Correspondingly, this support section could also be formed projecting radially inward on the first peripheral wall, if said further design is approximately realized.

The support section preferably does not engage in the threaded connection, but may, for example, fulfill a deflector function.

With regard to the disclosure, the ranges and / or ranges of values or multiple ranges given here, in particular with regard to the specified circumferential angles, also include all intermediate values, in particular in 1/10 increments of the respective dimension, if necessary also dimensionless. here in particular also with regard to the mentioned circumferential angles, on the one hand to delineate the stated range limits from below and / or above, alternatively or additionally but also with regard to the disclosure of one or more singular values from a respectively specified range.

The sizes of a part or of a region which can be taken from the drawing may initially have meaning with regard to a size ratio to another represented part or region of the same figure or another figure, the change mentioned in the same or with respect to the change of scale or a determinable one In particular, even if such a part or such an area is otherwise not described or mentioned in a claim. It can also have meaning as an absolute size.

Shown and described is a container 1, which consists of screw-connected parts, namely a container lid 2 and container bottom part 3.

The representation corresponds to a scale of 1: 2, but it can also be understood as a scale of 1: 1 accordingly.

The container base 3, as is further out Fig. 3 shows, has a second peripheral wall 4, which is formed to create the screw with two circumferentially separate from each other thread ribs 5 and 6. How about dating Fig. 10 results, the thread ribs 6 and 5 extend over a circumferential angle α of about 50 °. The circumferential angle α is measured starting from a central screw rotation axis A of the preferably rotationally symmetrical container lower part 3. Also the Container lid 2 is preferably formed rotationally symmetrical. It is understood that this rotational symmetry is given with the exception of the thread ribs, possibly of the support section 15 explained further below and / or designerischen specifics. A designerische special feature can be provided non-rotationally symmetrical particular from the technical aspect that, as explained, in any case preferred, in the closed state is always given the same circumference angle assignment of the container base to the container lid. The container lid can thus have, for example, a radially forming but vertically extending rib on a singular peripheral region, which in the closure state is then always in register with a rib of the container lower part that radially outwardly forms in the same sense.

At the lower lid part 3, as well as at the container lid 2, only the threaded ribs 5, 6, which are already specifically described for the container lower part, respectively, concerning the container lid 2, the threaded ribs 7 and 8 (cf. Fig. 8 and 9 ) educated.

The thread ribs 5, 6 and 7, 8 can be seen as out Fig. 10 respectively. Fig. 11 is also clear, without overlap in the direction of the screw axis of rotation A and practically opposite to each formed. In addition, between the thread ribs 5 and 6 or 7 and 8 in each case a circumferential distance corresponding to a circumferential angle β is given, cf. also about this Figures 10 and 11 which is significantly larger than the circumferential angle α and in the embodiment and preferably more than twice the circumferential angle α corresponds.

On the container lid 2 and the container base 3, as in the embodiment, only trained and in opposing thread ribs 5, 6 and 7, 8, the angle β is apparent as half of 360 ° minus twice the angle α.

The container 1 is further preferably a plastic injection-molded part, with plastic injection-molded parts in the form of the container lid 2 and the container base 3. For example, polypropylene or polyethylene as a material in question, or other suitable, especially in plastic injection processable plastic materials.

At one of the thread ribs 5 and 6, specifically at the container base 3 on the thread 5, a stop section 9 extending in the direction of the screw rotation axis A is formed, while with respect to the container lid 2 the stop section 9 is formed on the upper thread rib 7. "Upper" here means that the stopper portion 9 is formed with respect to the screw rotation axis farthest from a bottom 10 of the container 1.

The stopper portions 9 extend virtually perpendicular to the direction of extension of the respective thread ribs 5 and 6. They extend with respect to the container lid 2 in the direction of the ceiling and with respect to the container base 3 in the direction of the ground.

The second peripheral wall 4 of the container base 3 is visible on the bottom side via a paragraph 11 radially outward into a circumferential bottom wall 12 via. The paragraph 11 provides in the screwed according to Fig. 1 the visible parting line 13 between the container lid 2 and the container bottom part 3.

With regard to the abutment portions 9 mentioned above, it is also preferred that the threaded rib 5, together with the shoulder 11 for the retracting thread rib 8 of the container lid 2, form a limited opening in the direction of rotation as well as laterally in both directions of the screw rotation axis A. The width of the entry opening, ie their extension in the direction of the screw axis of rotation A preferably corresponds to the width of a related thread rib or is only slightly larger.

A same retraction opening forms the threaded rib 7 of the container lid 2 in cooperation with a right angle to the screw axis of rotation A upper side extending ceiling 14 or possibly a paragraph related thereto. In a circumferential gap between the thread ribs 5 and 6 of the container base 3 is seen in the embodiment, preferably also circumferentially, based on the said circumferential gap, a support portion 15 is formed. This makes it possible, according to a possible impressions of the first peripheral wall 16 in the closed state Fig. 2 to prevent. The support portion 15 does not otherwise engage in the locking of the parts to each other. It may be formed according to a thread rib with a slope, but it may also extend at right angles to the screw axis of rotation A.

When placing the container lid 2 and container base 3 to close the parts together, in a circumferential angular position of the parts to each other can already be achieved that the thread rib 8 of the container lid 2 in the circumferential gap between the thread rib 5 and the thread rib 6 of the container base 3 enters, as is the position of Fig. 4 would correspond. It then only requires a circa-quarter turn of the parts to each other, so that in Fig. 4 with respect to the thread rib 6 visible, pointing in the circumferential direction end face against the stopper portion 9, which is associated with the thread rib 7 of the container lid 2 is formed, moves. At the same time, the threaded rib 8 then moves against the abutment portion 9 of the lower threaded rib 5 of the container lower part 3.

But it may also be that such a circumferential displacement is given in vertical assembly of container base 2 and container lid 3, that the thread rib 8 of the container lid 2 is in a position in relation to the thread rib 5 of the container bottom part 3. Depending on the design, it may come to a certain Aufsitzen, with further movement in the direction but then separate the threads 5 and 8, and an end face 17 of the peripheral wall 16 can come into contact with the associated surface 18 of the paragraph 11 and thus the vertical assignment Determine container bottom 3 and container lid 2 for further closing.

In addition, a circumferential alignment may be provided that in screw-Verschließrichtung in the vertical collapse of the parts, the threaded rib 8 of the container lid 2 in the circumferential direction in front of the threaded rib 5 of the container base 3 is located. In such a case, the vertical installation of said surfaces 17 and 18 is then already given. The configuration may then be such that either the vertical spacing of the thread ribs 5 and 8 is such that they move over each other without touching each other or that the thread rib 8 is lifted by the thread rib 5 by a certain amount, but prevents the Threaded rib 8, the threaded rib 5 can go under. If it comes to the said lifting, then the surfaces 17 and 18 would again be somewhat spaced for this circumferential angle range.

The pitch of a thread rib 5, 6 or 7, 8, is preferably in the range of 2 ° to 4 °, more preferably 3 °.
