Description

Closure cap for a stamp and stamp therefor

Technical Field

The invention relates to a closure cap for a stamp and to a stamp for this purpose.

Background

From WO 2016/197172 a1, a stamp, in particular a frame (Stativ) stamp, is known, which comprises at least one stamp assembly and a stamping unit, wherein the stamp assembly is formed by an upper part which is formed in an arcuate manner and a lower part which has a stamp pad receiving element (kissenafnafnhemel). The stamping unit is connected in a movable manner in the lower part by means of a tilting mechanism, preferably with a slotted guide, to the upper part by means of a shaft or a journal, wherein in the rest position a text plate mounted on the stamping unit rests against an ink-impregnated stamp pad in the stamp pad receiving element. In the embossing process for producing the embossed impressions, the embossing unit with the text plate is adjusted into the embossing position via a tilting mechanism. Furthermore, a closure cap is shown, which is pushed with the narrow side onto the pressed stamp, so that the closure cap is held on a holding element on the housing of the lower part. The closure cap has a covering surface and two side walls molded on the longitudinal sides, wherein the side walls and the covering surface cover the interior of the stamp and the text plate attached to the stamping unit when the closure cap is pushed.

EP 1796909B 1 and EP 2634005B 1 disclose a closure cap made of plastic and a hand stamp, in particular a self-inking stamp. The stamp is formed here from an upper part and a lower part, wherein the upper part receives the lower part during the stamping process. In this case, the stamping unit, on which the text plate is mounted, is coupled to the upper part via a tilting mechanism in the lower part, so that the text plate mounted on the stamping unit is rotated by the tilting mechanism during the stamping process in order to produce the stamped impressions.

The closure cap is composed of a covering plate or covering surface and laterally encircling side walls, wherein the closure cap is fitted onto the hand stamp from below, i.e. from the support surface. The closure cap is connected to the shaft or shaft end (achstummel) of the stamp unit via a clamping device.

In the closure according to EP 2634005B 1, the closure is locked with the stamp unit in the pressed state of the stamp by means of a latching element, wherein the latching hooks are oriented inward in order to be able to lock with the stamp unit, in particular with a text plate carrier.

Closure systems are also known in which a fastening, in particular a snap lock, on the outer face of the stamp, in particular on the upper part of the self-inking stamp, is known, for example, from EP 0873245B 1.

For the sake of completeness, reference is made to closures in other types of seals, namely the so-called Flash seals (Flash-stamp) or Pre-colored seals (Pre-Ink-stamp), which must always be placed from below in order to close the tablet in order to prevent the Ink on the tablet from drying out. That is, if the stamp is placed too long without the closure being applied, the penetrating stamp ink will solidify, so that no further impression marks are used or only a greater part area is present.

The disadvantage of the closure described above is that, in order to release the closure, the closure can only be pulled out of the stamp with increased effort. In this case, it may happen that, as a result of the deformation of the latching hook, the latching hook breaks off or no longer returns to the initial position and therefore no longer provides a secure hold for the closure.

Disclosure of Invention

The object of the present invention is to provide a closure cap and a stamp therefor, in which the above-mentioned disadvantages are avoided and at the same time the user friendliness is increased.

This object is achieved by the invention.

The closure cap according to the invention is characterized in that two opposing actuating elements are arranged on the outer circumference of the cover cap, wherein at least one actuating element is flexibly or elastically connected to the cover cap or the side wall, wherein each actuating element has at least one latching element, in particular a latching hook, for hooking into or connecting with a latching projection in the interior or free space of the upper part of the stamp.

It is advantageous here that the closure cap can be released reliably and simply by using the actuating element, wherein at the same time a reliable retention can be ensured due to the formation of the latching hook. In this arrangement, the removal can take place without difficulty, since the user first presses the actuating element, so that the latching hook is pressed inward, and thus releases the locking with the upper part of the stamp, so that the closure cap can be removed without difficulty downward. A further advantage is that a higher holding force for the closure cap can be achieved, since the latching hook or the latching surface can be dimensioned larger, since the latching hook is moved by the actuating element for the purpose of engaging or disengaging the latching hook, so that an easy engagement and removal is possible.

The prior art solutions to date have no actuating element at all with which the locking element is moved, but rather merely plugged onto the stamp and removed. By arranging the catch element on a flexible actuating element, a preferably linear movement, in particular a path of movement, is achieved, so that the catch element of the closure cap is disengaged from the catch element on the upper part via the path of movement, so that the closure cap can subsequently be removed from the stamp without difficulty. The configuration of the latching elements, in particular the orientation of the latching hooks, can thus be realized in different ways, since the release of the latching connection is realized by the path of movement of the latching elements. Accordingly, in the specific description, different variants are described, such as the outward orientation of the latching hooks relative to one another on the closure cap, which latch into corresponding latching elements, in particular latching projections.

A configuration is advantageous in which the latching element, in particular the latching hook, projects outward, i.e. in the direction of the actuating surface of the actuating element. This makes it possible to achieve a simple design of the upper part in that a undercut (Hinterschneidung), in particular a latching edge, is required in the free space on the upper part, which can be produced simply and cost-effectively.

A further advantage is the feature for which two latching elements with outwardly directed latching hooks are arranged on the actuating element. This makes it possible to reliably hold the closure on the stamp.

The feature is advantageous for which the latching element, in particular the latching hook, is oriented parallel to the actuating surface of the actuating element. By means of the parallel orientation with respect to the actuating element, in particular the pressure surface, a stable design of the latching element can be achieved.

The feature is also advantageous for which two latching hooks are arranged on the actuating element, oriented parallel to the fastening surface, the projecting elements of which are directed opposite one another. This achieves that the pulling force is strengthened, so that the closure cap cannot fall off from the stamp due to vibrations.

The feature is advantageous for forming an intermediate space between the two latching hooks for receiving a latching projection of the stamp, in particular for receiving a latching projection mounted on the inner side of the upper part. This makes it possible to provide intermediate spaces between the projection elements for corresponding latching elements of the upper part, which are accommodated in the closure cap when it is connected to the stamp and are thus locked.

The feature is advantageous for the cover, the side walls and the flexibly actuable operating element to be formed in one piece, in particular as a single injection-molded part. This allows cost-effective production, since no assembly effort is required for producing the closure.

A feature is also advantageous for which a free space is arranged between the actuating element and the cover, in particular the bearing element, for the purpose of deflecting the pressure-loaded actuating element, in particular a latching hook arranged thereon (Ausweichen). This makes it possible, on the one hand, to mount the stamp securely on the support element and, on the other hand, to move the actuating element freely without interfering elements, in order to assemble or disassemble the closure cap without difficulty. A certain sealing can also be achieved by placing the lower part of the stamp onto the support element of the closure cap. In addition, it is achieved that the text plate, which is mounted on the stamping unit in the pressed state and which has been moved into the stamping position when the closure cap is mounted, is positioned between the support elements spaced apart from the closure cap, so that no indentations are formed in the text plate when the text plate rests against a part in the closed state. I.e. if the dial is pressed against a part or element over a longer period of time, the rubber of the dial is deformed, so that the impression quality is considerably degraded and the dial must be replaced. It is therefore important that the text panel is positioned freely when the closure is being pulled over, as is the case in the closure according to the invention. In this case, it is also possible to arrange a latching element on the support element or on the support surface for the lower part of the stamp, so that the stamp is initially placed on the support element and the lower part is latched together with the support element, so that the closure cap cannot be detached from the lower part any more, and then by adjusting the stamp into the stamping position, the latching hook of the actuating element latches onto the upper part and fixes it in the stamping position.

A further advantageous configuration is that the latching element, in particular the latching hook, is oriented in the direction of the actuating surface on the actuating element, whereby the latching hook is configured for latching in a latching projection on the inner face of the upper part of the stamp. This makes it possible for the latching hooks to point outward and thus to be introduced into the free space for the latching hooks when the closure cap is placed on the stamp and to engage in said free space, so that an invisible closure is achieved in the interior of the upper part. Furthermore, it is achieved by the outwardly oriented latching hooks that, when the actuating element is pressed, the latching hooks likewise move toward the center of the closure cap, i.e., inward, and can thus be easily released from the upper part.

A configuration is advantageous in which the actuating element is flexibly connected, in particular in a serpentine or meandering manner, to the cover and/or to the side wall by connecting webs. This makes it possible to adjust the actuating element or to deform the connecting web by means of a corresponding pressure action in order to release or to achieve the locking. In this way, a one-piece production of the closure cap with the flexible actuating element can be achieved.

A configuration is advantageous in which the two actuating elements are arranged opposite one another on the closure cap for actuation with only one hand, in particular two fingers. This is achieved in that the user can hold the stamp with one hand and simply release the closure cap with the other hand. There is therefore no risk of the hand being soiled by contact with the lettering plate, since the fingers are positioned on the outside of the closure cap, and when the closure cap is removed from the stamp, the lettering plate, in particular the stamping unit, automatically pivots back into the rest position of the stamp, in order to be able to absorb ink again from the stamp pad. Therefore, the finger is unlikely to come into contact with the letter plate provided with the stamp ink. A secure grip between the two fingers is also achieved by the oppositely disposed arrangement of the actuating elements.

A configuration is advantageous in which two opposite actuating elements are flexibly connected to the cover and/or the side wall. This makes it possible to remove or release the two latching hooks from the latching connection by simple pressing with two fingers, as a result of which a reliable release of the closure cap from the stamp can be achieved. It is therefore also possible to displace the latching hooks relative to one another by pressing when the closure is mounted on the stamp, so that the latching hooks can be pushed into the free space of the upper part of the stamp without difficulty. In order to fix the closure cap, the pressure application to the actuating element then only has to be terminated, so that the latching hook is moved outward again into its rest position and rests against the latching projection in the free space of the stamp. It is of course also possible to assemble or fix the closure without pressure, wherein the closure is positioned in such a way that the latching hook can be pushed into the free space of the stamp, so that subsequently the closure only has to be pressed against the stamp without actuating the actuating element, as a result of which the latching hook and the actuating element are correspondingly deflected or pressed inward. If the latching hook reaches the latching projection, the latching hook can be pivoted back again into its rest position, i.e. now pivoted outward, and thus latched on the latching projection.

It is therefore also possible to simply press the closure cap against the stamp or press the stamp against the closure cap, so that the stamp is also pressed, whereby the locking elements of the closure cap and of the stamp are locked in the free space of the upper part and thus the stamp is held together with the enclosed closure cap in the pressed position. The flexible design of the connecting web and the actuating element also prevents the latching hooks from being reliably deflected and from being broken off again when the closure cap is pushed on with full force.

A configuration is advantageous in which a protective bow (Schutzb gel) is arranged in the region of the actuating element, which protective bow is connected to the cover and/or the side wall. This makes it possible to prevent inadvertent opening of the stamp with the enclosed cover during transport due to the pressure of the object on one or both actuating elements. That is, the protective bow is designed such that the user now has to consciously grasp the control surfaces with the fingers in order to be able to squeeze them. The protective bow should therefore form a so-called stop to prevent undesirable pressure forces acting on the actuating element.

A configuration is also advantageous in which actuating elements in the form of actuating surfaces are formed on the side walls and the opposing actuating elements are flexibly connected to the closure cap. This provides a secure holding of the finger even with only one flexible actuating element, since the actuating surface is provided, for example, with anti-slip means, in particular grooves.

A configuration is advantageous in which a protective arch is arranged in the region of the actuating element, which protective arch is connected to the cover and/or the side wall. This prevents the enclosing cover from being easily released, for example when transporting a stamp with the enclosing cover fitted, since the protective bow protects the actuating element against involuntary forces. In this case, the protective bow is arranged in the transition region or corner region of the bottom and of the side wall of the closure. In order to avoid unintentional manipulation of the handling element, for example due to foreign objects during transport in the bag, the handling element is retracted such that the handling surface extends behind the outer faces of the side walls and the protective bow. The retracted control surface must therefore be grasped consciously by the fingers in order to operate it.

A configuration in which one or more flexible actuating elements are designed as multiple parts, in particular as a base body and a pressure plate, is advantageous.

The two components can thus be produced in a simple manner with different materials and colors. For example, the pressure plate, on which the fingers are positioned when handling the closure, may be formed of a non-slip material for reliable operation, while the closure itself is made of a cost-effective material. An important advantage is achieved if the two components, i.e. the closure cap, in particular the cover cap and the side walls, are produced in a different color than the pressure plate, wherein preferably black is used for the closure plate and red is used for the pressure plate. The user can therefore immediately recognize the position of the actuating elements or pressure plates by means of the red pressure plate and can simply and quickly actuate these actuating elements or pressure plates. As a result, the closure is also visually assigned more value (aufwetten) and therefore creates a high-quality impression.

The object of the invention is also achieved by a stamp device, wherein the closure cap is designed according to the invention and a latching projection is arranged on the upper part of the stamp for latching with a latching element on the actuating element. It is advantageous here if a closure cap is provided, the latching element of which is moved by the actuating element. In this case, the blocking element is disengaged from the corresponding blocking element on the stamp by a displacement, in particular a linear movement, of the blocking element, so that the closure cap can then be removed from the stamp without difficulty. At the same time, however, a very high holding force is achieved in the plugged state, since the latching projections of the latching elements can be designed to be correspondingly large, since they are not released by force action, in particular by pulling the stamp and the closure cap apart, but rather by moving the latching elements on the closure cap.

The feature is advantageous for which a free space is arranged between the upper part and the lower part of the stamp for introducing the latching element, in particular the latching hook of the closure. This achieves that the closure of the closure cap with the stamp is carried out on the inner side of the upper part, so that the locking element is protected by the upper part. Furthermore, the orientation of the latching projections of the latching elements can be oriented outwards or parallel to the inner side of the upper part.

A configuration in which the latching hook of the closure cap and the latching projection between the upper part and the lower part are latched in a free space is also advantageous. It is thereby possible that specially adapted latching projections can be formed or arranged on the upper part in order to achieve the required or desired holding force for the latching connection.

A configuration in which the latching element is adjustable, in particular movable, on the closure cap by means of an actuating element is also advantageous. This makes it possible for the blocking element of the closure cap to be disengaged from the blocking element on the stamp, in particular on the upper part, by actuating the actuating element in order to release the locking between the closure cap and the stamp, and for the closure cap to be subsequently pulled out of the stamp without difficulty.

The object is also achieved by a stamp, wherein a free space is arranged on the upper part, which is formed in the direction of the interior space, for receiving a latching element of the closure, wherein a corresponding latching element, in particular a latching projection, is arranged in the free space for latching with a latching element, in particular a latching hook, molded on the closure.

In this case, it is advantageous if the upper part is locked to the closure cap in the pressed state of the stamp, so that the stamp is held in the pressed state. At the same time, it is achieved that the closure cap is pressed firmly against the lower part of the stamp as a result of the restoring force acting in the stamp as a result of the spring, so that a very good seal and contamination prevention are achieved. Furthermore, the stamp with the enclosed cover fitted thereon is also reduced in size, so that for example a simpler storage in a drawer or a simple transport is possible. By using a closing cap, it is also possible to avoid unintentional pressing of the stamp during transport, which inevitably leads to contamination of the applied object with stamp ink, since the stamp is fixed in the pressed position.

Finally, a configuration is advantageous in which the actuating element of the closure cap is arranged freely accessible below the upper part when the closure cap is mounted on the stamp. This makes it possible for the user to easily access the actuating element, so that a quick and simple release of the closure cap from the stamp can be achieved.

Detailed Description

It is initially provided that identical components in different figures are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred in a meaningful manner to identical components having the same reference numerals or the same component names. The positional references selected in the description, for example upper, lower, lateral, etc., also refer to the drawings described and are to be transferred in the sense of a change of position to a new position. Individual features or combinations of features of the embodiments shown and described can also constitute independent inventive solutions per se.

Fig. 1 to 8 show a closure cap 1 for a stamp 2, in particular for a self-inking stamp 2.

The stamp 2 comprises at least one upper part 3, a lower part 4 and a stamping unit 5, wherein the stamping unit 5 is connected or coupled to the upper part 3 via a tilting mechanism 6, in particular via a runner rail 7 in the lower part 4. Furthermore, a spring element 8 for returning into a rest position 9 is arranged between the upper part 3 and the lower part 4, wherein, during the embossing process for producing an embossing impression (not shown), the embossing unit 5 with the text plate 10 fixed thereon can be adjusted via the tilting mechanism 6 into an embossing position 11 or an embossing location 11, which approximately corresponds to the transport position or storage position 11 with the encased closure 1. In the rest position 9, the text plate 10 mounted on the stamping unit 5 is oriented in the direction of the stamp pad receiving element 12 in the lower part 4, so that the text plate 10 for receiving the stamp ink rests on the stamp pad 13 impregnated with the stamp ink when the stamp pad 13 is in use. Such a structure of the stamp 2 with the corresponding components is inevitably known from the prior art, so that no further discussion is given to the interaction or functional principle. It is also known that such a stamp 2 can be provided with a closure cap 1.

According to the invention, a new type of closure 1 is now described, which can be preferably applied to a self-inking stamp 2. In principle, if the lower part or stamp pad holder of the respective pre-colored stamp or flash stamp is correspondingly designed to correspond to the closure cap 1, the closure cap 1 can also be used for so-called pre-colored stamps or flash stamps, for which purpose the free space is integrated with a latching element, in particular a latching projection, as will be explained below. Furthermore, a stamp 2 according to the invention, in particular a so-called self-inking stamp 2, is described, which is designed for using a closure cap 1, wherein the stamp 2 and the closure cap 1 can be designed for all shapes, such as circular, rectangular, square, oval. In the exemplary embodiment shown, a circular stamp 2 with a circular closure cap 1 is selected, so that in other shapes, corresponding adaptations must be made.

The closure 1 comprises at least one plate-shaped cover 14 or cover surface 14 with side walls 15 projecting in one direction and at least one internally located support element 16 for placing or erecting the lower part 4 of the stamp 2. The support elements 16 extend in the direction of the projecting side walls 15, but the height 17 of the support elements 16 is preferably smaller than the height 18 of the side walls 15. It is also possible here for the side walls 15 to be constructed at different heights.

Furthermore, at least one actuating element 19 is arranged on the outer circumference of the cover 14 and/or on the side wall 15, which actuating element is flexibly or elastically connected to the cover 14 and/or the side wall 15 and/or the support element 16. The exemplary embodiment according to fig. 3 shows two actuating elements 19, which are connected to the side wall 15 by means of flexible connecting webs 20. In this case, it is possible for the actuating element 19 to have anti-slip means on its actuating surface 21, which can be formed, for example, by grooves, markings or other materials, so that a secure finger hold is achieved.

In order to be able to connect the closure cap 1 to the stamp 2, the closure cap 1 has at least one outwardly directed latching element 22, in particular a latching hook 23, wherein the latching element 22 is arranged or molded on the actuating element 19 and extends in the same direction as the side wall 15. Preferably, at least one latching element 22, in particular a latching hook 23, is provided on each actuating element 19, wherein in the exemplary embodiment of fig. 3 the latching element 22 is formed by two latching hooks for each actuating element 19. However, it is also possible to use only one detent element 22 on one actuating element 19 and, instead of a second detent element 22, a support element (not shown) on the other actuating element 19, which support element can be arranged on the stamp or on the closure cap 1. It is also possible that only one latching element 22 is formed flexibly by the flexible actuating element 19 and the other second actuating element 19 and the latching element 22 arranged thereon are formed fixedly or rigidly, so that the latching connection can be released or established only by the flexible actuating element 19.

The actuating element 19 is preferably fastened to the cover 14 or the side wall 15 or the support element 16 by means of connecting webs 20, wherein the actuating element 19 is connected to the side wall 15 according to fig. 3. The two actuating elements 19 are held in position by preferably four connecting webs 20, wherein the connecting webs 20 are configured flexibly so as to be able to be moved or adjusted accordingly when the actuating elements 19 are subjected to pressure, wherein the actuating elements are always automatically returned into the initial position again. According to the embodiment of fig. 3, the connecting tab 20 is configured in a serpentine or zigzag shape. The material thickness for the connecting webs 20 can thus be designed to be correspondingly large, wherein the flexibility of the connecting webs 20 is nevertheless maintained. However, in order to be able to carry out such a deformation or adjustment, a free space 24 is arranged between the actuating element 19 and the cover cap 14, in particular the support element 16, for the purpose of being deflected when the actuating element 19 is subjected to pressure, i.e. when the actuating element 19 is pressed, the connecting web 20 is deformed in such a way that the actuating element 19 is moved or pressed into the free space 24 together with the molded latching element 22, so that the free space 24 is reduced, wherein after the pressure application has ended, the connecting web 20 returns again into the initial position and therefore the actuating element 19 is again positioned in the initial position.

Furthermore, it can be seen from fig. 3 that all elements, in particular the cover 14, the side walls 15 and the actuating element 19 which can be actuated flexibly via the connecting webs 20, are formed in one piece, in particular as a single injection-molded part, with the latching element 22 arranged thereon. In one working step, the closure cap 1 can therefore be produced cost-effectively without additional assembly effort, wherein ABS is preferably used as the material.

However, in order to be able to fix the closure cap 1 to the stamp 2, the stamp 2 must have a free space 25 between the upper part 3 and the lower part 4. The size, in particular the length and the width, of the free space 25 is designed to accommodate the latching element 22 and also has a corresponding latching element 26, in particular a latching projection 27, on the inside. Preferably, the upper part 4 is in this case slightly outwardly curved in the region of the free space 25, as can be seen in fig. 1 and 2, so that the free space 25 is formed only in the region of the curvature, i.e. the free space 25 is of only limited design. However, a design of the upper part 4 with a free space 25 over the entire circumference with latching projections 27 arranged or molded therein would be possible, so that the closure cap 1 can be slipped on in any desired location. The latching elements 26, in particular the latching projections 27, are preferably formed in one piece, in particular by injection molding, with the upper part 4.

The closure 1 can be fixed by placing the closure 1 flat on a flat surface 28, in particular an office desk, on which the stamp 2 is positioned above the closure 1 (see fig. 1) and subsequently placed on the closure 1, so that the lower part 3 lies flat on the support surface 16 (see fig. 2). The stamp 2 can then simply be pressed so that the latching elements 22, in particular the latching hooks 23, are pushed from below into the free spaces 25 of the upper part 3 and are correspondingly deformed or pressed back until the latching hooks 23 reach the level of the latching projections 27 and are thus returned again into the rest position, so that the latching hooks 23 latch onto the latching projections 27.

In order to release the closure cap 1, the stamp 1 must now be held in one hand, so that the actuating element 19 is pressed with the other hand, in particular with two fingers. As a result, the latching hook 23 is moved back again, so that the latching with the latching projection 27 is released and the closure 1 can be pulled down, so that the latching hook is pulled out of the free space. It should be mentioned here that, when the latching connection between latching hook 23 and latching projection 27 is released, stamp 2 is immediately adjusted into the rest position 9 by spring element 8, so that closure 1 can be removed simply.

Fig. 4 shows a further exemplary embodiment of the closure cap 1. The actuating element 19 is now connected to the bearing surface 16 via the connecting web 20.

Fig. 5 shows an embodiment in which the actuating element 19 is connected to the cover cap 14 or the cover surface 14, i.e. to the bottom of the closure cap 1, via a connecting web 20, so that, when pressure is applied to the actuating element 19, the latching element 22 is pivoted or tilted toward the center of the cover cap 14 and can thus be released from the latching connection. In contrast to the other exemplary embodiments, the detent element 22 on the actuating element 19 is not moved horizontally, but is adjusted by a rotational movement.

Fig. 6 also shows an embodiment in which a safety bow 29 is arranged, which protects the actuating element 19 against unintentional pressure loading when the stamp 1 is transported. The safety bow 29 is arranged here in the region of the bottom or cover surface 14, so that the actuating element 19 is arranged above. The safety bow 29 is connected to the side wall 15 and/or the cover 14. It is advantageous here that the actuating element 19 is not designed flush with the outer face of the safety bow 29, but that the actuating element 19 is slightly retracted, so that a finger must be positioned consciously on the retracted actuating element 19 in order to actuate it. The arrangement of the safety bow 29 has shown that, when the stamp 1 is transported in the pocket, unintentional opening due to the application of external object pressure to the actuating element 19 is avoided. In principle, the structure of fig. 6 corresponds to the embodiment according to fig. 3 with a serpentine or zigzag shaped connecting tab 20.

Fig. 7 and 8 show a further exemplary embodiment of the closure cap 2, in which the actuating element 19 is now of multi-part design, wherein the actuating element 19 is formed from a base body 30 and a pressure plate 31. The base body 30 is in turn connected to the side walls 15 or the cover 14 via flexible connecting webs 20, which are now configured to be bent, whereas the pressure plate 31 is fixed to the base body 30 of the actuating element 19. The pressure plate 31 is preferably fixed by a snap-in connection, so that during production only the pressure plate has to be pressed onto the base body 30. For this purpose, one or two parts 33 are arranged on the rear side 32, which parts 33 are inserted into corresponding latching openings 34 on the base body 30, thereby locking the pressure plate 31 to the actuating element 19. The pressure plate 31 now has an actuating surface 21, so that, when pressure is applied to the pressure plate 31, in particular to the actuating surface 21 of the pressure plate 31, the base body 31 is pressed inward or rearward, so that the latching hooks 23 projecting outward on the base body 30 are likewise displaced and thus the latching hooks 23 are disengaged when they are fastened to the stamp 1, so that the closure 1 can be removed.

In such a configuration of the actuating element 19 with the pressure plate 31, it is advantageous if the pressure plate 31, i.e. the so-called actuating button, can be produced from another material or color, so that the user can easily perceive the pressure plate 31. Fig. 8, for example, shows a representation of stamp 1 with a nested closure cap 2, in which a pressure plate 31 is shown, while the closure cap 2 itself is produced in black. The position of the pressure plate 31 for actuation can thus be seen immediately, so that the user can grasp the pressure plate 31 between two fingers in a targeted manner and apply a corresponding pressure in order to release the latching hook 23 from the stamp 1 and pull the closure cap 2 away downward.

It can also be said that the production of the closure cap 2 in multiple parts, although slightly increasing the production process or assembly, significantly increases the user comfort, since the color contrast can thus be produced in a simple manner. It is also possible for the pressure plate 31 to be provided with a marking, for example by laser engraving, which marking forms a color change during the engraving, so that the marking is well visible and shows the region of the pressure plate 31.

As can be seen from the figures, the pressure plate 31 is designed such that it covers not only the base body 30 but also the lateral connecting webs 20, so that only the pressure plate 31 and the housing of the closure cap 2 are visible to the outside. At the same time, protection against contamination is thereby achieved.

In the above-described exemplary embodiments, it is essential to realize the closure cap 2 and the associated stamp 1, wherein one or two actuating elements 19 are arranged on the closure cap 2, which are moved by the application of pressure in order to release the closure cap 2 from the stamp 1. Previous solutions of the prior art do not have an actuating element 19 of this type, but merely have to be plugged onto the stamp and removed therefrom.

The invention also discloses two further embodiments of a stamping device with a stamp and a closure that can be plugged onto the stamp, wherein a modified arrangement of the latching connection between the stamp and the closure is used or applied.

According to the invention, the closure cap is provided as before with at least one, preferably two, flexible actuating elements. The actuating element is arranged opposite one another on the closure cap, so that the closure cap can be clamped or held between two fingers of one hand, so that the stamp can be held with the other hand.

In this case, however, in order to connect the two components, i.e. the closure cap and the stamp, the closure cap is preferably laid flat on a flat surface, in particular a writing desk, and then the stamp is placed on the closure cap, in particular on a support element or a support surface, and is locked by means of a stamping process, whereas the removal or removal of the closure cap is preferably carried out in such a way that the stamp is held in one hand and the closure cap is held on two actuating elements between two fingers of the second hand, in particular the thumb and the index finger, and the latching connection is released by applying pressure to the actuating element, so that the closure cap can be pulled out of the stamp.

In this new embodiment, the structure of the base body of the closure corresponds to the previously described variant of fig. 1 to 8, in particular to the configuration of the cover surface 14, the side wall 15, the bearing surface 16, the actuating surface 19 of the connecting web 20, the safety bow 29 and the pressure plate 31, or can be configured in different variants, so that a detailed description of these components is omitted.

The embodiment variants differ in the design of the latching connection between the closure cap and the stamp. In this case, the latching elements on the actuating element are no longer directed outward, but are rotated through 90 °, so that the orientation of the latching hooks extends parallel to the actuating surface. In this case, it is possible to arrange only one latching hook or also two latching hooks and, wherein a configuration with two latching hooks and is advantageous, since the retention of the sealing cap on the stamp is improved.

The two latching hooks and the projection elements extending therefrom, i.e., the latching hooks, are oriented toward one another so as to engage with one or both latching projections on the stamp in the intermediate space formed by the two latching hooks.

It can also be said that the latching projection of the stamp, which is arranged on the inner side of the upper part, is accommodated in the intermediate space of the two latching hooks, and thus a latching connection is established. It has proven advantageous here for the detent projections to be v-shaped, so that when the closure cap is placed on the stamp, the detent hooks are pressed slightly away from one another on the actuating element of the closure cap by the v-shaped surfaces of the detent projections until they are pushed onto the detent projections and then pivot the projection elements back into the rest position, so that the detent projections are accommodated in the intermediate space, i.e. the projection elements lie on the upper side of the detent projections and fix or hold the closure cap before it is detached from the stamp.

However, in order to be able to release the closure from the stamp, one or more actuating elements on the closure must now be actuated by applying pressure. This is advantageously achieved by two fingers of one hand, so that the actuating element is pressed, i.e. moved in the direction of the center of the closure. The catch hooks arranged or molded on the actuating element therefore also move. In this case, the latching hook must be moved linearly with the actuating element for such a long time that the latching projection is pushed out of the intermediate space between the two latching hooks, so that the closure cap can be removed downward, i.e., from the stamp.

As in the exemplary embodiment of fig. 1 to 8, the removal of the closure cap from the stamp is therefore effected again by actuating the actuating element.

It is of course also possible to use a construction in which the latching hooks are not directed opposite one another, but are directed in the opposite direction, i.e. outwards. In this case, a separate detent projection is assigned to each detent hook, so that the detent projections lie flat on the upper side after the closure cap is plugged onto the stamp, and thus prevent the closure cap from falling off from the stamp. The stamp is closed with a closure cap, wherein the latching hooks (wherein only one latching hook may also be used) point outward, wherein the latching hooks are oriented parallel to the actuating surface of the actuating element.

Finally, it is pointed out in accordance with the regulations that the system 1 and its components or the structures of its constituent parts are not shown in part to scale and/or in enlargement and/or in reduction.
