Abstract

The invention relates to a protective sleeve (1,1a,1b,1c) for objects (10,10a,10b,10c), for example for packaging knives, saws, pliers or surgical instruments or the like, having a rear handle or grip region in the form of an unprotected region (15) and a front danger region (11) to be protected against gripping, which danger region can be pushed into an at least one-sided open end opening (4) of the protective sleeve (1,1a,1b,1c) and is enclosed there by a receiving space (2,3,8), wherein the protective sleeve (1,1a-1c) has at least one locking region (5) which secures the inserted object (10,10a,10,10c) against longitudinal movement in the protective sleeve and is elastically deformable by hand and can be opened.

Description

Protective sleeve for objects

Technical Field

The present invention relates to a protective sheath for an object.

Background

Such protective sheaths are provided, for example, for packaging knives, other sharp objects, such as saws, surgical instruments, and forceps, and the like. In the same way, the protective sleeve according to the invention is used for packaging and storage of splinting and stabbing weapons and for protection against injury.

It is currently known exclusively in the prior art to construct protective sleeves for such objects in such a way that a protective sleeve which is open on one side is available, with which the object to be protected can be inserted into the open end-face opening of the protective sleeve in the region to be protected against gripping.

In the case of protective sleeves for packaging knives or cleaving and puncturing weapons, it is therefore known to insert the cutting edge of the knife or cleaving and puncturing weapon through an end opening of the protective sleeve which is open on one side, in order to be able to receive the cutting edge in all possible positions in the protective region of the protective sleeve. One known application is the storage of rival and stab weapons in weapon sheaths.

However, a disadvantage of the protective sleeves known to date which are open on one side is that there is no locking against longitudinal movement. A further disadvantage is that the protective sleeves known to date likewise have only a low mechanical stability in the case of small wall thicknesses, since they have no mechanical reinforcement and the like, in particular in the insertion region. For this reason, there is also the risk that the upper insertion region of the protective sleeve is accidentally damaged in the event of insertion of an object to be protected, in particular a knife.

Due to the fact that, in the case of the known protective sleeves, there is no locking of the object to be accommodated there as protection against longitudinal movement, there is the further disadvantage that such protective sleeves cannot be hung in a vertical position at a presentation wall. There is then the risk of the object slipping out.

Although it is known in the state of the art that friction-increasing bumps or the like are mounted at the inside of a protective sleeve placed at the surface of the object to be protected, they are not sufficient when it is a heavy object which is furthermore suspended at a demonstration wall in a vertical position.

Disclosure of Invention

The invention is therefore based on the object of improving a protective sleeve of the type mentioned at the outset in such a way that it provides a longitudinal locking of the object to be accommodated as protection against longitudinal movements, it is protected against damage in the case of an object insertion, and it can be operated more easily by hand and can be produced at lower cost.

The essential feature of the invention is that the protective sleeve which is open on one side in a known manner now has at least one locking region in which one or more locking elements are arranged which interact with an associated stop surface and/or undercut on the object to be held and which is designed as an elastically deformable deformation region, it being possible in the case of its actuation to achieve that the locking elements arranged in the locking region can be brought out of engagement with associated counter-elements on the object to be held.

This results in a completely new type of support for the object to be protected in the protective sleeve. It is assumed here that the object has an area to be protected, which is configured, for example, as a blade or as a saw or as a forceps element or the like, and which is therefore completely accommodated in the protective sheath. The danger zone should be protected against external grasping, since injury or infection risks or other risks result from it.

Furthermore, a further region is to be connected to the region of the object to be protected, in which a counter-element of the object to be protected is arranged, which co-operates with an associated locking element on the side of the protective sleeve, wherein a rear region is connected to the counter-element of the object, which is a non-protective region and which is configured, for example, as a handle or a clamping thread or, more generally, a machine socket of the object to be held.

This only then results in the possibility of achieving a longitudinal locking for the object contained in the protective sleeve that can be opened by hand force.

In a preferred embodiment of the invention, it is provided that a locking element arranged in the protective sleeve at the upper free end is arranged in the elastic deformation region of the protective sleeve, so that when the protective sleeve is pressed, the locking element is disengaged from an associated counter-element at the object.

However, the invention is not limited to this, i.e. the locking element is at the free insertion end of the upper part of the protective sleeve in the locking region of the protective sleeve. It can be arranged anywhere in the region of the protective sleeve with respect to its longitudinal extent, and this applies equally to the counter-elements at the object to be held, since these counter-elements must be arranged not only in the transition region between the protective region and the non-protective region of the object, but also in the protective region itself.

When reference is made in this specification to an object to be protected in a configuration as a knife with a sharp cutting edge, the invention is not limited thereto. All objects may constitute the contents of the protective sleeve as long as they fulfil the features mentioned before and after.

In addition to the previously mentioned objects, all other objects can also be accommodated, which are associated with a packaging for the object to be protected. It is not necessary here that the object has a protective region. For example, pliers, scissors and the like may likewise be accommodated without depending on the protection of the pliers or the scissors elements.

It is important in the context of the present invention that the protective sheath provides effective protection against injury, since it is no longer readily possible to pull the object to be protected out of the protective sheath. In this case, the hand force required to actuate the locking regions, which are formed as elastically deformable deformation regions according to the invention, must be used in order to actuate the walls of the protective sleeve lying opposite one another in the deformation regions with the locking elements arranged there, i.e. the spacing between the locking elements is increased and the locking elements are thus disengaged from mating elements arranged on the object.

Obviously, the invention also protects the reversal of the movement according to the locking principle of the invention:

in accordance with the above description, it is stated that locking elements, which are arranged opposite one another and in alignment opposite one another, are arranged in the deformation region on the inside of the protective sleeve, preferably in the form of projections, ribs or other projections.

The invention is however not limited to an arrangement of locking elements aligned with each other, which are placed opposite each other. It can also be provided that such a locking element is arranged only at one side in the deformation region, while the opposite wall is smooth and free of locking elements.

The reversal of the movement according to the invention is also applicable to both embodiments, in that there are in each case outwardly directed grooves or other outwardly projecting projections in the side walls parallel to one another, and in that a projecting counter element is provided at the object to be held, which engages into the projection on the protective sleeve side and locks the object to be held there.

Likewise, the two movement embodiments (described as reversal) can likewise be arranged in one of the forms on one of the sides of the side walls of the protective sleeve in the deformation region, while on the opposite side the movement reversal of the locking element is arranged.

With the arrangement of the locking element as a projection of the protective sleeve on at least one side of the deformation region and as an inwardly directed projection on the opposite side, an insertion fixation is also achieved in such a way that the object to be held can only be pushed in a defined insertion position, but it cannot be held in an insertion position rotated by 180 degrees.

In a further development of the invention, it is provided that the end of the object, which is configured as an unprotected region and has, for example, a handle, a clamping support or the like, can additionally be closed with a protective cap. The protective sleeve is then likewise open on one side and pushed onto the end of the object to be held, i.e. onto the unprotected region, and can be locked in any desired manner with the rear open end of the protective sleeve. A plug or detent connection or a rotary connection or the like can be realized here.

A further advantage is obtained in the case of the use of a protective sleeve which can be plugged, latched or screwed onto the free and open end of the rear part of the protective sleeve, i.e. the region can be sealed, so that there is a hermetically sealed protective packaging.

The invention is not limited to the profile shape of the protective sleeve shown here in the figures and to the protective covers which may be combined therewith. The contour of the protective sleeve shown here relates in particular to an approximately rectangular, oval or polygonal contour of the protective sleeve. The invention is not limited thereto. The protective sleeve can likewise be designed as a round profile protective sleeve, wherein the profile shapes can differ from one another in different regions of the protective sleeve. For example, the protective region of the protective sleeve, into which the part of the object to be protected can be accommodated, has a comparatively different contour shape compared to the contour shape of the locking region configured as deformation region.

Furthermore, a further section of the protective sleeve can be connected to the deformation region, which is preferably arranged in the region of the end-face opening of the protective sleeve, can be profiled in any desired manner and is suitable in particular for receiving a protective sleeve to be pushed, latched or screwed onto this region.

If, for example, a circular contour region is associated with the protective cap at the deformation region, the protective cap to be inserted or screwed thereon can likewise be circularly contoured and provided with suitable threads.

Another embodiment relates to a protective sleeve made of two half-shells, which can be connected to one another along a dividing plane extending in the longitudinal direction of the object to be packaged. The two half-shells can be constructed mirror-symmetrically to one another. In a further embodiment, however, the contour of one of the half-shells can differ from the contour of the other half-shell.

The two half-shells can be completely separated from one another in the first embodiment and they are combined in this case to form a complete protective packaging by a locking connection arranged between the half-shells on the edge side.

In a further embodiment, the two half-shells can however be arranged pivotably to one another at one longitudinal side by means of one or two film hinges. To close the protective packaging, the two half-shells are then pivoted relative to one another along the pivot axes of their longitudinal sides into the closed position. The closed position is then locked and fixed by a locking device, which is located opposite the film hinge and is preferably also arranged on the edge side between the two half-shells.

All the matters and features disclosed in the attached abstract, particularly the spatial arrangements shown in the drawings, are to be understood as being essential to the invention, insofar as they are novel, individually or in any combination, with respect to the prior art.

Detailed Description

Figures 1 and 2 show the basic principle of a protective sheath that can be changed in a variety of ways. The protective case 1 according to fig. 1 is substantially formed by two side walls 2 lying opposite one another and preferably parallel to one another, which form a receiving space for an object 10 to be received between them, wherein the two side walls 2 are connected to one another at the end faces by longitudinal end walls 8 and the ends of the protective case 1 are closed by end walls 3. The protective sleeve is preferably designed as a hollow blow-molded part or as a diecast part, so that all wall parts of the protective sleeve are preferably integrally connected to one another.

In a further embodiment, however, it can be formed from parts which are additionally connected to one another. For example, the side walls 2 may be connected to the separate longitudinal end walls 8 via gluing, welding or locking methods.

The invention is not limited to protective sleeves 1 which are closed at the ends. The end wall 3 can likewise be dispensed with and it can be profiled in any desired manner.

At the side opposite to the end wall 3, the protective sleeve 1 constitutes an end opening 4, which is provided as an insertion opening for an object 10 to be inserted there.

The protective sleeve is divided into different zones. A larger and longer area of the protective sleeve is used for accommodating the object 10, more precisely the hazardous area 11 to be protected, which is thus inserted into the protective sleeve 1 via the end-face opening 4.

In a preferred embodiment, the protective sleeve 1 has a locking region 5 in the region of its end-face opening 4, in the region of which at least one locking element 9 is arranged, which interacts with an associated

counter-element

13,14 at the object 10.

In the following description of the figures it is assumed that the locking elements 9 are configured as inwardly directed projections, ribs or similar locking elements which are aligned with one another and lie opposite one another.

In the general description, however, it has been pointed out that it is sufficient to use only one single locking element 9 on a side wall, which locking element interacts with an associated counter-element 13 or 14 at the object 10.

In the case of a reversal of movement, it is also possible for the locking elements 9, which are formed in the form of cams and are formed so as to point inward and face each other in alignment, to be formed as outwardly pointing projections, wherein only one single outwardly pointing projection is sufficient, which cooperates with the associated

counter element

13,14, wherein in this case the counter element is then formed as an outwardly protruding cam on the object 10.

The locking region 5 is configured as a deformation region 31, by means of which the locking element 9 can be brought out of engagement with the counter-element 13,14 at the object 10.

As is only schematically shown in the drawing, the locking region 5, which at the same time forms the deformation region 31, is arranged in the vicinity of the open end-face opening 4. The invention is not limited thereto. The locking region 5 can likewise be arranged, for example, in the middle region of the protective sleeve 1, whereby the end opening 4 then becomes longer and the insertion region is likewise thereby formed.

Correspondingly, the locking region 12 at the object 10, corresponding to the locking region 5 of the protective sleeve 1, then likewise has to correspond to the locking region 5 which is displaced in the longitudinal direction.

Fig. 1 and 2 likewise show that, when an object 10 is accommodated in the protective sleeve 1, the right end of the protective sleeve 1 can be closed by a protective cap 6, wherein the protective cap can be releasably connected to the protective sleeve in any desired manner. It can be fixed to the protective sleeve 1 by plugging, latching, welding, gluing or screwing.

The protective cap 6 is therefore plugged, screwed or latched onto the end-face opening 4 of the protective sleeve 1 in the direction of the arrow 7.

The present invention allows the protective sleeve to be fully released in which profile configuration it is configured. Thus, the region in which the object 10 is joined with its region 11 to be protected can be contoured in a rectangular or oval or circular or polygonal shape or be configured in any other shape.

The same applies to the locking region 5, the contour of which can be designed in any desired manner and which can therefore likewise be of rectangular, polygonal, square or circular configuration.

The protective cap 6 to be plugged or latched is then adapted to the contour shape in the region of the end-face opening 4 of the protective cap 1.

Generally, the use of the protective cover 6 is not necessary. The unprotected area 15 of the object 10 to be held then protrudes from the right end of the protective sleeve 1 and does not require further protection.

This is preferred in particular in the case of packaging knives and similar objects, such as for example splinting and stabbing weapons, since the user can then inspect the knife handle and can evaluate the material of the knife handle.

The new protective sleeve likewise offers the possibility of enclosing sensitive knives and the like in the protective sleeve, the receiving end of which projects freely from the rear end of the protective sleeve. In this way, it is likewise possible to introduce the tool to be protected together with the protective sleeve into the receiving region of the machine tool or generally into the support, and to remove the protective sleeve from the object to be protected by manipulation of the deformation region 31 only when the tool is fixed in the receiving region.

The protective sleeve according to the invention thus makes it possible to fit the object to be protected in the machine receiving area.

In fig. 3, a side view of the protective casing with a knife 20 is shown, which knife has not yet been completely inserted into the protective casing 1 in the insertion direction (arrow direction 25).

The knife consists of a blade 21 which protects the area to be protected from grasping and shows the area 11 to be protected and a handle 22 which is attached to the non-protected area 15 at the blade 21 which defines the object.

The knife is therefore inserted in the direction of the arrow 25 into the front opening 4 of the protective sleeve 1, wherein in the embodiment shown the handle 22 has a bevel 23 at its front end and a finger guard 26 coupled thereto, which prevents the hand grasping the handle 22 from sliding forward onto the blade 21.

Behind the finger guard 26, an undercut 24 is arranged, which serves as a

counter element

13,14 in the sense of fig. 1 and 2.

In the region of the protective sleeve 1, in the region of the side walls lying opposite one another, there are also two centering blocks 18 lying opposite one another, the mode of operation of which is illustrated with reference to fig. 12.

Furthermore, the protective sleeve 1 is closed at the end and has a penetration protection 17, which is explained with reference to fig. 10 below.

Furthermore, a stop wall 19 is provided on the side of the deformation region 31 on the protective sleeve 1, which stop wall interacts with the inclined surface 23 on the handle 22.

The stop surface is likewise shown in fig. 1 and interacts there with an associated stop surface 30 on the object 10 to be protected, as is shown in fig. 2.

With the interaction of these two stop regions, a reliable stop restriction of the object 10 to be held in the protective sleeve 1 is thus ensured and prevented in that the object 10 to be protected is inserted too far into the protective sleeve 1 in the longitudinal direction.

The function of the stop wall will be further explained in fig. 13.

It is important in any case that the stop wall 19 is adapted to the contour of the end face of the handle 22, so that the two stop faces 19,23 lie flush against one another and high loads are transmitted.

It is clear that the adaptation is different in other cases of the object, so that the stop wall can be constructed straight and in fig. 1a straight plane 23 is indicated, which co-operates with the associated stop surface 30 of the usual object 10.

An advantage of such an arrangement of the stop wall is that the end of the protective sleeve 1 on the end side is thus reinforced and thus a delimiting or dividing of the insertion region of the protective sleeve in the direction of the deformation region 31 at the rear end of the end-face opening 4 is achieved.

On the left side of the stop wall 19, the protective sleeve 1 is therefore preferably not deformable or is constructed from a relatively non-deformable plastic material, whereas on the right side of the stop wall 19 a deformation region 31 is provided, in which the deformation region 31 is deformed by finger pressure in the direction of the arrow 33 (see fig. 4) in such a way that the two opposing locking projections 27 are moved away from one another (see arrow direction in fig. 4) and the previous locking contour 16 is deformed in the deformation region 31 into an enlarged locking contour 16', so that the two opposing locking projections 27, which are arranged flush with one another, are brought into engagement with the undercuts 24 at the handle 22 of the knife 20.

The insertion movement of the knife 20 in the case of crossing the deformation region 31 is shown in fig. 4. It is shown that the undercut 24 deforms itself in the locking region 5 by means of an insertion force in the direction of the arrow 25, and the locking contour 16, which was previously approximately rectangular, expands arcuately, as is shown in fig. 4, in order to thus move the two locking cams 27, which are situated opposite one another, away from one another and to be brought out of engagement with the undercut 24 at the handle.

Fig. 5 shows, on the contrary, the fixed insertion position of the knife 20 in the protective sleeve 1, where it can be recognized that the finger guard 26 now passes over the locking cam 27 and rests below the locking cam 27, so that the locking cam 27 rests in the region of the undercut 24 and there is thus an absolute fixing against longitudinal movement of the knife 20 in the protective sleeve 1 according to fig. 5.

In fig. 6 the locked insertion position of the knife 20 according to fig. 5 is shown. It can also be seen that the bevel 23 on the handle side is now located on the stop wall 19 on the protective sleeve side and therefore results in an effective securing against longitudinal displacement. The blade tip 28 preferably has a distance 29 from the penetrating protection 17 arranged there.

Fig. 7 now shows the mechanical deformation of the deformation zone 31 of the protective sleeve 1 in the locking zone 5.

If a pressure is applied to the protective sleeve 1 with finger pressure or mechanically on both sides in the direction of the arrow 33 against the associated faces in the deformation region 31, the previously approximately rectangular locking contour 16 becomes a convex locking contour 16', and the locking cams 27 which are situated opposite one another in the locking region 5 on the inner side of the locking contour 16 and which are arranged flush with one another in the direction of the arrow 34 in turn assume their pulled-out position according to 27'. Thus, the object to be held can be easily pulled out of the protective sheath.

Fig. 8 shows, as an example for a possible wall thickness, that the pressure of the longitudinal end walls 8 lying opposite one another must be sufficient to bulge the side walls 2 lying opposite one another in the manner according to fig. 7.

The invention is not limited thereto. Instead of applying a pressure in the direction of arrow 33, it is sufficient to apply an asymmetrical pressure, in which, for example, a pressure is applied to diametrically opposite transition edges between the longitudinal end wall 8 and the associated side wall 2.

It is also sufficient if the pressure is exerted in the direction of the arrow 33 from only one side, when the opposite side is seated on the associated stop face.

The invention is not limited to the contour shape shown here of the side wall 2 and the longitudinal end wall 8 adjoining it. The side walls can likewise be configured (at least in the deformation region 31) as an S-shaped profile in order to make possible a better bulge of the shape of the locking profile 16' according to fig. 7. Such an s-shaped contour has the advantage that a very large deformation width starting from the locking contour 16 up to the locking contour 16' can be achieved with relatively little finger pressure.

Fig. 9 shows by way of example only, that in the deformation region 31 opposing gripping grooves 32 are provided, which are likewise intended to be tactilely recognizable, i.e. the deformation region 31 can be deformed according to the form of fig. 7 by finger pressure against the two opposing gripping grooves 32 (see also fig. 11).

Fig. 10 shows a so-called penetration protection 17. It is formed by two mutually opposite and mutually connected rib regions, which are welded in the contact region and thus form a stable counter surface at the tip 28 of the cutting edge 21.

The gripping groove 32 may likewise be coated with a suitable gripping facilitating surface structure 35.

Fig. 12 furthermore shows that in the region of the protective sleeve, there can also be oppositely situated and oppositely directed centering blocks 18, which are placed on both sides on the flat side of the object to be held, in particular on the cutting edge 21, in order to thus hold the cutting edge centered in the region of the protective sleeve 1. In other embodiments, however, these centering blocks 18 can likewise be omitted or can likewise be present in multiples.

The centering block 18 can have any desired shape, and it can likewise be of rib-like design.

Fig. 13 shows the insertion position of the handle 22 into the end opening 4 of the protective sleeve 1 and generally shows the placement of the stop wall 19 on the protective sleeve side on the bevel 23 on the blade side. Thus, a secure and high load-transmitting fixation in the longitudinal direction for the object to be held is ensured.

Fig. 14a to 14g show different embodiments of the projection 27 in top view and in cross section, which are therefore marked with lower case letters a to g according to embodiments thereof.

The upper illustration is correspondingly a top view towards the respective projection 27 and the illustration below is the contour shape of the same projection.

Each projection 27a-27g preferably has a lead-in chamfer 37, via which the object 10 to be held can be easily pushed, and when it is in its locking position, an associated stop face 38, which is preferably bent or inclined, is placed at the object 10 in such a way that it can only be removed with difficulty from the block 27 beyond this stop face 38.

Furthermore, fig. 14a shows an approximately rectangular projection with a wedge-shaped contour, fig. 14b shows an oval projection with a supporting airfoil contour, fig. 14c shows a tear-drop-shaped projection in top view and likewise shows the supporting wing principle, fig. 14d shows an oval projection with a semicircular contour, fig. 14e shows a round projection likewise with the supporting wing principle, fig. 14f shows an oval projection with an oblique extension of the supporting airfoil contour and fig. 14g shows a curved projection likewise with an oblique extension of the supporting airfoil contour.

Fig. 15 shows the use of an adhesive label 36 as a fixing against pulling out and as an anti-theft protection, which serves as an operational protection measure. The sticker 36 is applied not only laterally to the end opening 4 of the protective sleeve 1 but also to the handle 22 in order to facilitate an undesired removal of the marking knife 20. If the knife 20 is pulled out, the sticker 36 is destroyed.

For the sake of simplicity, only the sticker 36 is shown as being affixed to one of the side walls 2 of the protective sleeve 1. In a further embodiment, one or more such adhesive labels 36 can likewise be applied to one or more of the longitudinal end walls 8 or at other locations.

The adhesive label 36 can likewise be configured in the form of a sleeve.

Fig. 16 to 18 show different profile shapes of the profile of the protective sheath at least in the deformation zone 31. It is also shown by means of generic fig. 1 and 2 that the contour of the protective sleeve 1 on the side of the deformation zone 31 can likewise differ from the contour in the deformation zone.

Fig. 16 therefore shows only approximately rectangular contour 16a, which is transformed into curved contour 16 a', when two opposite longitudinal end walls 8 of protective sleeve 1 in deformation region 31 are pressed together with a suitable pressing pressure.

In contrast to this, fig. 17 shows that at least the deformation region 31 can be embodied elliptically and thus forms a locking contour 16b, which can be converted into an enlarged elliptical shape of the locking contour 16 b' by finger pressure in the direction of the arrow 33.

Fig. 18 shows that the locking contour 16c is at least likewise formed by a plurality of polygonal cross sections, which are preferably symmetrically configured, and that the locking contour is converted into a locking contour 16c' shown in solid lines when pressed onto suitable opposing longitudinal end faces of this locking contour 16 c.

Fig. 19 and 20 show further examples for supporting an object in the protective sleeve 1. The protective sleeve 1a shown here is suitable for accommodating, for example, scissors, which are generally referred to as objects 10 a.

It is characteristic for this form of protective sleeve that the deformation region 31 is directly coupled to the insertion region, and that two mutually parallel and

adjacent locking projections

27a,27b are arranged in the insertion region (deformation region 31), which engage into the associated grip openings of the scissors and thus fix the scissors against being pulled out of the protective sleeve 1.

Only when the protective area is elastically deformed due to finger pressure in the direction of the arrow 33 towards the deformation area 31, the locking

projections

27a,27b arranged in pairs aligned with each other and facing each other are moved away from each other and the scissors can therefore be easily removed from the protective sleeve 1.

Furthermore, all other features described in connection with the previous fig. 1 to 18 also apply to this embodiment according to fig. 19,20 to 23.

Fig. 20 shows, as a further example, that it is not necessarily necessary to apply deformation work in the direction of the arrow 33 by hand force in the deformation region 31. It is shown that the forceps halves themselves can be pressed in the direction of the arrow 33 in the case of a supported forceps, whereby the locking cams 27, which are situated opposite one another in the middle region between the forceps halves, are pressed, whereby the protective sleeve 1 is spread open and the forceps can therefore be pulled out of the protective sleeve 1 in the case of a pressed handle.

It has already been emphasized that instead of the

projections

27,27a,27b and 27c lying opposite one another, it is also sufficient to arrange such projections only at one wall of the protective sleeve 1. The same applies in particular to the embodiments according to fig. 19 and 20.

Fig. 21 and 22 show a flat object 10c, which is designed, for example, as a medical knife, saw or, in general, as a medical instrument, which has a receiving region 39 on its rear side, with which the object 10c can be clamped in the receiving device. The same applies here, in that the object 10c has an undercut designed as a mating element 13 and which cooperates with an associated locking cam 27 in the side wall of the protective sleeve 1.

In the vertical plane of the

parts

13,27 which engage in a fixed position relative to one another, handle projections 40 which are situated opposite one another are provided in the protective sleeve 1 in the region of the side walls 2 and which project in the plane of the respective side wall 2 and, in the event of compression thereof, produce an expansion of the material of the side wall 2, so that the side wall 2 is deformed in the deformation region in the manner shown in fig. 22. The locking cam 27 on the protective sleeve side is thus disengaged from the undercut on the object side in the form of the mating element 13, and the object can be pulled out of the protective sleeve 1c with its receiving region 39.

Fig. 23 shows a section through an object 10c to be held in the region of the counter element 13.

Figures 24 to 27 show another embodiment of the protective sheath in which like parts are provided with like reference numerals.

Fig. 24 shows a perspective illustration of a first embodiment of a protective sheath, which is substantially formed from two half-shells 1d-1d that can be connected to each other in a lockable manner.

In the exemplary embodiment according to fig. 26, it is shown that the two half-shells 1d-1d are designed mirror-symmetrically.

In the exemplary embodiment according to fig. 27, it is shown that such half-shells 1e to 1f can likewise be designed non-mirror-symmetrically.

In the perspective illustration according to fig. 24, a total of two different embodiments are identified for which separate protection is required.

The first embodiment, which is referred to in connection with fig. 26 and 27 in fig. 24, relates to the fact that the two half-shells 1d-1d or 1e-1f can be completely detached from one another and are not connected to one another in the open state by means of a connecting element.

As a connecting piece for two half-shells, which therefore have a longitudinally continuous dividing surface 47, a locking connection on the edge side is provided.

This latching connection is present according to fig. 24 both at the upper longitudinal edge and at the lower longitudinal edge of the

half shells

1d,1d associated with one another.

The latching connections are arranged at a distance from one another and each latching connection is formed in this embodiment by a latching tab 41 with a latching rib pointing backwards, which engages in an associated, oppositely situated groove in which a latching web 42 is arranged, one face of which is directed obliquely, in order to be undercut by the obliquely backwards pointing latching tab.

By configuring the locking piece 41 elastically, the locking connection can be easily released by pressing towards the packaging.

The same locking connection is also formed at the lower longitudinal edge of the two half-shells.

Fig. 24 therefore shows that the two half-shells 1d-1d or 1e-1f are completely separated from one another in the unlocked state and can be connected to one another only in the region of the dividing plane 47 in a lockable manner.

However, in the example according to fig. 24, a second embodiment is also indicated, which is only illustrated graphically. It is stated here that in the region of the lower longitudinal edge 43, a film hinge 46 can be present in sections or extending over the entire longitudinal edge 43, so that the two half-shells 1d-1d or 1e-1f can be connected to one another in a pivotable manner in the region of the longitudinal edge 43 and can be pivoted to one another in the direction of the arrow 45 and can be locked to one another by the previously mentioned

locking connections

41, 42.

It is characteristic for all embodiments that the deformation zone 31 according to the invention is also present in the case of these embodiments in order to thus make easy opening of the package possible.

According to fig. 24, the

locking connection

41,42 is opened by pivoting it open in the opposite direction to the arrow direction 45, or in a further embodiment, the two half-shells are pressed against one another in the arrow direction 44, in order to bring the

locking connections

41,42 associated with one another into engagement.
