Description

The invention relates to a convertible into a frame packaging that can be converted from a packaging state into a frame state.

From the DE 10 2011 115 255 B3 a box for a puzzle is known, which consists of a lower part and a lid, each having a base plate and a plurality of inner side walls forming. On the base plate is a jigsaw frame, which has the dimensions of the puzzle assembled to the whole and consists of a plurality of frame parts arranged. The frame parts are movably arranged on the base plate and can be folded from a position projecting into the interior space into a position fixing the puzzle as a whole.

The known box has a relatively high cost of materials, since the base surface of the base plate is substantially larger than the size of the finished puzzle. Due to the large footprint, the space requirement of the box is large. This is a hindrance when stowing the box in cabinets or shelves. Finally, the possibility of folding the frame parts increases the design complexity of the known box.

The invention has for its object to provide a convertible into a frame packaging that can be produced with low material costs, has a small footprint and can be easily converted from a packaging state to a frame state.

This object is achieved by a convertible into a frame packaging with the features of the protection claim 1. Advantageous developments of the packaging according to the invention are the subject of protection claims 2 to 14.

In the packaging according to the invention, a carrier plate and a lid member are parallel to each other on the frame member in the covering arranged one above the other in the packaging state and each form a flat, ie no paragraphs having, top and bottom of the package. The base of the package is therefore determined only by the size of the support plate or the lid member. For example, if the packaging is for storage a puzzle is used, the puzzle pieces can be stored in the space between the support plate and the lid member. The packaging may also be used for other purposes, such as the storage of colored pencil images, a game board or the like.

The main technical result achievable by the invention is a material saving in the manufacture of the package, since substantially all sides of the package are formed by elements usable in the frame after the package has been converted into the frame.

The cost of materials for the production of the packaging is therefore low. The package can also be easily brought from the packaging state to the frame state and vice versa.

In the most preferred embodiment, the profile of the upper wall of the frame member abutting the upper edge of the outer wall of the frame member is formed with at least one step having upper and lower legs, the upper leg being closer to the outer wall of the frame member is as the bottom one. The arrangement of the lid member on the lower leg of the step allows the lid member to be used as one of the sides of the parallelepiped shaped package. Firstly, due to the formation of the steps in identical profile for all four sides of the frame member, a decorative element is formed which makes the frame more attractive; secondly, the step-limited recess formed thereby is used to place therein the cover member, thereby reducing the vertical size the packaging is reduced. The lid member can be received under tension in this recess, which makes it possible without the use of a holding element for fixing the lid member in the recess, which is formed by the step in the profile of the upper wall of the frame member in the packaging state.

Preferably, the thickness of the lid member is equal to the height of the step, which makes it possible to steplessly form the surface formed by the lid member and the upper wall of the frame member, which in turn simplifies the storage and unimpeded shifting of the package in the horizontal plane.

The formation of a side wall on the periphery of the back surface of the carrier plate allows effective enlargement of the interior of the package by the carrier plate is arranged in the packaging state with the front surface to the outside, whereby the spacing of the carrier plate and the lid member in the packaging state is increased by an additional distance that corresponds to the height of the side wall. In this embodiment, for the conversion of the package to the frame state, it is only necessary to turn the carrier plate with its front surface disposed on the side of the upper wall of the frame member, and the outer surface of the side wall to the inside of the lower edge of the outer wall of the frame Frame element is created.

Preferably, on the inside of each of the four outer walls of the frame member at least one support member is formed with a support surface projecting from the lower edge of the outer wall to the height of the side wall of the support plate. In this case, in the packaging state, the side wall abuts the support surface of the support member so that the front surface of the support plate is flush with the end surface of the lower edge of the outer wall of the frame member. These support elements determine the position of the support plate in the surrounding frame element at its periphery. Most preferably, an embodiment of at least two projections on each of the inner sides of the outer walls of the frame member, whereby at the same time a bending deformation of the carrier plate inserted into the frame member is prevented. For greater stability, it is preferable to arrange the position of the support plate in the frame member on the inner surface of the corners of the frame member, and to arrange at least one protrusion in the middle of each of the four sides of the frame member.

The highest practical and aesthetic value has a frame member whose upper wall on the inside has an arcuate end portion with an edge portion arranged parallel to the outer wall. The arrangement of the end surface of the edge portion of the upper wall of the frame member in a plane with the support surface of the support member allows enlargement of the contact surface of the front surface of the support plate and the elements of the inside of the frame member, which enables a more stable positioning of the support plate in the frame member as well to achieve a reliable fixation of the cover element in the case of its arrangement between the support plate and the frame member.

In a preferred embodiment, the carrier plate is semitransparent with a light-diffusely transmitting surface or completely transparent. This makes it possible to illuminate the packaging in the frame condition from behind. If the carrier plate is made completely transparent, the contents of the package can be viewed through the carrier plate, or the carrier plate can be used as a transparent protective layer in this case, when the lid member is mounted with the image mounted thereon in the frame state on the back surface of the carrier plate ,

The support plate can be formed either continuously or with a plurality of openings or with a plurality of depressions or as a rigid mesh with meshes of predetermined size, which greatly increases the range of use of the packaging. For example, the plurality of openings distributed on the entire surface of the support plate can be used for the composition of a mosaic, the parts of which presuppose the presence of openings for their attachment to the support plate. The package can also be used to assemble a 3D puzzle made on the horizontal surface of the backing plate. The apertures or recesses disposed on the entire surface of the backing plate enable the attachment of a 3D puzzle to a vertical surface, thereby creating spatial or composite models or composite representations. The apertures or recesses in the backing plate can also be used for even accommodation of any objects, such as when confectionery is placed in a confectionery box on a special base which serves as a sort of organizing element for housing. The preparation of the support plate as a rigid grid or arranged on the entire surface openings can serve to reduce their weight. This reduces the manufacturing costs of the packaging according to the invention.

Preferably, the lid and the frame member and the support plate are held in the packaging state by at least one fixing element in position.

In one embodiment, the fixing element has two cover sections arranged at a distance one above the other, each with two side edges extending at right angles to one another. The cover sections are connected in the region of the side edges by a side wall extending perpendicularly to them. The fixing elements are pushed in the packaging state on the opposite corners of the package.

The fixing element may also be designed in the form of at least two clamping brackets which hold together their elements in the packaging state.

Alternatively, the fixing element may be formed as one or more turnbuckles, which contracts the support plate and the lid member together and pass through the cavity of the packaging, which is formed between the support plate, the frame member and the lid member.

A likewise possible embodiment of the fixing element is a cardboard envelope which completely surrounds the side of the packaging formed by the lid element and in the collapsed state surrounds only the edge of the carrier plate at its circumference with a band whose width is three to twenty percent of the width of the carrier plate, i. the distance between the opposite longitudinal sides, is. Preferably, the width of the band is four to ten percent of the width of the carrier plate. When the support plate is transparent, this embodiment of the fixation element allows the view of the packaging enclosed thereby through the transparent support plate, while preserving the parallelepiped shape of the packaging.

In the case where the frame member is formed so as to enable the attachment of its outer wall to the lateral sides of the carrier plate under tension in the packaging state as well as in the frame state, there is no need to use the fixing element for fixing at least the carrier plate to the frame element. while in the case when the lid member is formed so that it can be fixed under tension of its lateral sides in the recess formed by the step in the profile of the upper wall of the frame member, the necessity of using the fixing member also for the attachment the lid member in the recess of the frame element deleted. Nevertheless, in order to achieve a higher degree of reliability of attachment of the lid member, the frame member and the carrier plate, in the packaging state, even in case of fixing the carrier plate or the lid member under tension in the frame member, a fixing member may be used.

The carrier plate preferably has a plurality of openings arranged at a distance from one another adjacent to the circumference. The frame member has projections which are formed to engage in the openings in the frame state and in the packaging state. hereby a secure hold of the frame elements is ensured both in the frame state and in the packaging state.

This secure hold can be further improved by covering the inner surface of the openings at least partially by an elastic material having a thickness which allows the projections of the frame elements to be held under tension.

In order to provide a visually appealing continuous frame, the length of the transverse limbs of the frame member between the corresponding corners of the limbs delimiting them substantially corresponds to the length of the transverse side of the support plate and the length of the longitudinal limbs of the frame member substantially between the limbs of the limbs delimiting them Length of the longitudinal side of the carrier plate.

Fig. 1 shows a perspective view of a preferred embodiment of the package 10 with spaced apart elements. The packaging 10 comprises a flat rectangular support plate 11 with a side wall 18 arranged at its circumference, a frame element 19 and a rectangular cover element 60, wherein the cover element 60 and the support plate 11 in the packaging state are spaced apart on a frame element 19 and arranged congruently one above the other and parallel to one another are, wherein the frame member 19 serves as a spacer which holds the cover member 60 and the support plate 11 at a predetermined distance from each other, without that they bear against each other in the packaging state.

The support plate 11 is made of transparent material and has two opposite longitudinal sides 13, 14 and two perpendicular thereto extending opposite transverse sides 15, 16. The carrier plate 11 has a front side 70 and a rear side 72 (see FIG Fig. 3 . 4 . 6a, 6b . 8th . 10 . 12 ), wherein the front side 70 of the support plate 11 in Fig. 1 is down and the back 72 is facing up. Alternatively, the support plate 11 may be formed either continuous and non-transparent or with a plurality of openings or as a rigid mesh with meshes of predetermined size. It is important that the carrier plate 11 be sufficiently rigid to maintain its shape during assembly with and separation from the frame member 19, and not bend in the packaging state under the action of conventional packaging. At each of the lateral sides 13, 14, 15, 16, the support plate 11 is at its rear surface 72, ie in Fig. 1 formed on the frame member 19 side facing a continuous side wall 18, wherein in a section through a parallel to the support plate 11 extending plane, the distance between the outer edges of the opposing walls 18 in its entire height is constant.

Alternatively (in Fig. 1 not shown), the wall 18 may be interrupted or formed as a single protrusions.

Between the carrier plate 11 and the lid member 60, the frame member 19 is positioned parallel to them.

The frame member 19 has longitudinal sides 23, 24 and transverse sides 25, 26, which extend at right angles to each other. The length of the longitudinal sides 23, 24 corresponds substantially to the length of the longitudinal sides 13 and 14 of the support plate 11, while the length of the transverse sides 25, 26 corresponds to the length of the transverse sides 15 and 16 of the support plate 11.

The frame member 19 has a peripheral outer wall 40 which forms the outside of the frame member 19. The outer wall 40 has a lower edge 43 and an upper edge 44, wherein in the packaging state, the support plate 11 is disposed in the frame member 19 on the side of the lower edge 43, while the cover member 60 on the side of the upper edge 44 of the upper wall 40th the frame member 19 is arranged. At the upper edge 44 is on the inside of the frame member 19, the upper wall 42 of the frame member 19, whose outer circulation along each of the longitudinal and transverse sides 23, 24, 25 and 26 of the frame member 19 is formed equal. The profile of the upper wall 42 of the frame member 19 is formed with a step 80 having an upper leg 82 and a lower leg 81 (see FIG. Fig. 3 and Fig. 4 ). The step 80 is formed at a uniform height and formed at a uniform distance from the outer wall 40 along the entire length of the longitudinal and transverse sides 23, 24, 25, 26 of the frame member 19. Beginning at the lower leg 81, the upper wall 42 extends arcuately downward, ie in the direction from the upper edge to the lower edge of the outer wall 40 of the frame member 19 with a parallel to the outer wall 40 extending edge portion 41 inwardly, the lower edge parallel extends to the lower edge of the outer wall 40 and ends above this, relative to the plane of the frame member 19, as in Fig. 3 and Fig. 4 shown. As a result, a trough-shaped depression is formed on the underside of the frame element 19. At the bottom of this trough-shaped support elements 29 are formed at regular intervals along each of the sides 23, 24, 25, 26 formed as partitions in the trough-shaped wells, the support surface 45 extends perpendicular to the outer wall 40. The support surface 45 of the support elements 29 is used in the packaging state for the arrangement of the end face of the side wall 18 of the support plate 11 thereon. The support surface 45 protrudes from the lower edge 43 of the outer wall 40 by the height of the wall 18, so that in a concern of the wall 18 on the support surface 45 of the support member 29 in the packaging state, the front surface 70 of the support plate 11 flush with the end face of the lower Rands 43 of the outer wall 40 is arranged. This allows one of the surfaces of the packaging to be replaced by the support plate 11 and the end surface of the lower edge 43 of the outer wall 40 of the frame member 19 is formed to form a flat surface without heels.

In place of in Fig. 3 shown embodiment of the support member 29 as a continuous partition in a trough-shaped recess may be formed on the back of the outer wall 40, the support member 29 as a projection with a triangular sectional area in the vertical section, the support surface 45 in a plane with the end face 47 of the inner edge portion 41 of the upper Wall 42 is located as in Fig. 4 shown. The support surface 45 extends from the inner surface of the outer wall 40 of the frame member 19 in the interior of the frame member 19 at a distance corresponding to the thickness of the side wall 18 of the support plate 11. This embodiment of the support member 29 allows a further saving of the material from which the frame member 19 consists.

As in Fig. 3 and Fig. 4 As shown in packaging, the outside of the side wall 18 of the support plate 11 is close to the lower part of the inside of the outer wall 40 of the frame member 19, wherein the lower part adjacent to the lower edge 43 of the outer wall 40. This makes it possible to fasten the outer wall 40 of the frame element 19 under tension on the lateral sides 13, 14, 15, 16 or on the side wall 18 of the carrier plate 11.

The rectangular lid member 60 is formed continuous and non-transparent with sufficient star pitch to prevent bending deformation when used as one of the sides of the package, as in FIG Fig. 1 shown to resist. Typical forces in the field of use of the packaging, for example, forces that are caused by gripping movements of the fingers of the hand when the package is gripped from two sides with your fingers. The length of the lid member 60 corresponds to the length of the step 80 of the profile of the upper wall 42 of the frame member 19 at its longitudinal sides 23, 24, corresponding to its width corresponds to the length of the step 80 at its transverse sides 25, 26. This allows the lid member 60th to be arranged on the lower leg 81 of the step 80. It is, as in Fig. 3 and Fig. 4 the thickness of the lid member 60 is equal to the height of the step 80, which makes it possible to continuously form the side of the package formed by the lid member 60 and the upper leg of the step 80, with the outwardly facing surface of the lid member 60 is arranged flush with the upper leg 82 of the step 80. Alternatively, the thickness of the lid member 60 may differ from the height of the stage 80. This difference is preferred not more than 30% of the level of level 80 (not shown). If necessary, to avoid the use of additional elements for attaching the lid member 60 to the frame member 19 according to an embodiment of the invention, the lid member 60 is adapted to be secured under tension of its lateral sides in the recess extending from the step 80 of FIG Profils the outside of the upper wall 42 of the frame member 19 is formed. According to a further embodiment of the packaging, which in Fig. 1 is illustrated, the dimension of the lid member 60 corresponds to the outer dimension of the outer wall 40 of the frame member 19. According to this embodiment of the packaging, however, the use of at least one of the below-mentioned embodiments of the fixing elements is required.

Fig. 2 shows the package 10 in opposite Fig. 1 reverse view, so that the support plate 11 is located at the top, while the lid member 60 (in Fig. 2 not shown) below. One of the possible variants, the carrier plate 11, the frame member 19 and the lid member 60 together, is in Fig. 2 in which the packaging elements are held together by two fixing elements 30, 38, which in FIG Fig. 2 are shown in a position prior to placement on the respective opposite corners of the package 10.

Each fixing element 30, 38 has two cover segments 31, 32, which are arranged one above the other in cover, and which have the shape of a right-angled triangle with a vertex 36, from which two side edges 33, 34 extend at right angles to one another. The side edges 33, 34 of the upper deck section 33 and the lower deck section 32 are interconnected by a side wall 35 extending perpendicular to the deck sections 31, 32. In the area of the hypotenuse of the cover sections 31, 32 there is no side wall. The distance between the cover sections 31, 32 corresponds to the distance between the cover element 60 and the support plate 11 in the in Fig. 2 shown packaging condition. The fixing elements 30, 38 are placed on the opposite corners of the package 10.

Besides the use of in Fig. 2 shown fixing elements 30, 38, other embodiments of the fixing elements are possible. For example, the fixing elements may be formed as two clamping brackets (not shown), which hold together the lid member 60, the frame member 19 and the support plate 11 in the packaging state. Alternatively, the above-mentioned packaging elements can be applied by adhering flat self-adhesive elements contiguous portions of the carrier plate and the frame member or the lid member and the frame member are held together (not shown). Alternatively, the fixing element may be formed as a turnbuckle, which passes in the packaging state through the cavity of the package and the support plate and the lid member at at least one point connects to each other (not shown). In addition, as stated above, instead of using the fixing members, the support plate and the lid member may be held together by the frame member by being held under tension in the frame member.

To the in Fig. 2 shown packaging 10 in the frame 100 to convert the first embodiment in Fig. 5 and Fig. 6a, Fig. 6b is shown, the lid member 60 is taken out of the recess formed in the frame member 19 by the step 80, and on the side of the lower edge 43 of the outer wall 40 of the frame member 19 on the end face 47 of the edge portion 41 of the upper wall 42 of Frame member 19 is placed, then the support plate 11 is placed on the side of the lower edge 43 of the outer wall 40 on the cover member 60, wherein the front surface 70 of the support plate 11 is applied to the cover member 60. The attachment of the support plate 11 in the frame member 19 is achieved in that the outside of the side wall 18 of the support plate 11 engages under tension with the inside of the outer wall 40 of the frame member 19, as in section in FIG Fig. 6a and Fig. 6b shown. For fixing the position of the lid member 60 between the inner edge portion 41 of the upper wall 42 and the support plate 11, protrusions may be formed on the inner side of the upper wall 42 or the outer wall 40 in the plane in which the lid member 60 is disposed (not shown) ), which prevent a lateral displacement of the lid member 60.

In Fig. 6a schematically shows a cross-section of the converted into the frame packaging at a portion of the frame member 19, wherein the inner surface of the upper wall 42 of the frame member 19 is formed as a trough and has no support member. In Fig. 6b a cross-section is shown at a portion of the frame member 19 having a support member 29 which is formed as a continuous partition wall in the above-mentioned trough, which is formed on the inside of the outer wall 42. At this portion of the frame member 19, the contact area between the frame member 19 and the lid member 60 in comparison to the portion of Fig. 6a increased.

Fig. 7 and Fig. 8 show a second embodiment of the packaging converted into the frame, the difference to the first, in Fig. 5 and 6a, 6b illustrated embodiment in that on the support members 29 pin-shaped projections 46 are formed, which extend parallel to the outer wall 40, wherein the lower end of the pins 46 is at the height of the lower edge 43 of the outer wall 40 of the frame member 19, ie in the plane passing through the lower edge 43 of the outer wall 40 parallel to the plane of the frame member 19. The pins 46 preferably protrude from the inner surface of the outer wall 40 of the frame element 19 by the thickness of the side wall 18 of the carrier plate 11.

As it is in Fig. 7 can be seen, 11 openings 50 are formed on the inside of the side wall 18 adjacent to the outer periphery of the support plate. The openings 50 are arranged so that the pins 46 engage the frame member 19 in these openings when the frame member 19 is fitted so that the inside of its outer wall 40 abuts the outside of the side wall 18, as in Fig. 8 is recognizable.

The frame member 19 can be placed so far on the peripheral portions of the support plate 11 until the end face 47 of the edge portions 41 rests on the front side 70 of the support plate 11. However, they can also be moved upwards to a certain extent, so that the cover element 60, a sheet of paper, cardboard or the like can be pushed under the end face 47 of the edge portion 41.

The openings 50 in the carrier plate 11 are arranged so that the pins 46 of the frame member 19 both in the in Fig. 8 shown position, that is, when the front surface 70 of the support plate 11 is aligned with the side of the upper wall 42 of the frame member 19, as well as in the reverse position, such as in Fig. 3 and Fig. 4 (Without the pins 46) shown, ie, in a position in which the rear surface 72 of the support plate 11 is aligned with the side of the upper wall 42 of the frame member 19, pass through them. This allows a secure attachment of the support plate 11 in the frame member 19 in both the frame and in the packaging position.

In Fig. 9 and Fig. 10 FIG. 3 shows a third embodiment of the packaging convertible into a frame 100, which is analogous to that in FIG Fig. 5 and Fig. 6a, 6b illustrated embodiment, but with the difference that the cover member 60 is disposed in the frame state on the back surface of the support plate 11. In this embodiment correspond the longitudinal and transverse dimensions of the lid member 60 the distances between the inner surfaces of the respective side walls 18 of the support plate 11. Thus, the cover member 60 can be arranged between the side walls 18 of the support plate 11 and fixed its position laterally, or alternatively, a fixture under tension between the Side walls 18 take place. When the support plate 11 is made transparent, this embodiment makes it possible to provide effective mechanical protection of the image applied to the surface of the cover member 60 abutting against the back surface 72 of the support plate 11. Alternatively, the lid member 60 may be formed by any known method, such as sticking, sticking of adhesive elements to the rim portions, and the like, in US Pat Fig. 10 be shown attached position.

Fig. 10 shows the cross section of a portion of the frame member 19 without support member. At the portion of the frame member with the support member 29, the cross section of the frame member 19 looks as in Fig. 6b ,

In Fig. 11 and Fig. 12 FIG. 4 shows a fourth embodiment of the box-to-frame package, which differs from that in FIG Fig. 7 and Fig. 8 2 differs only by the sequence of the arrangement of the elements to each other, namely according to the fourth embodiment ( Fig. 11 . Fig. 12 ), the front surface 70 of the support plate 11 at the inner edge portion 41 of the upper wall 42 of the frame member 19, while the cover member 60 is disposed adjacent to the back surface 72 of the support plate 11. The transverse dimensions of the lid member 60 are according to this embodiment designed so that the lid member 60 is fixed under tension between the pins 46 of the frame member 19 on the rear surface 72 of the support plate 11.

All parts are preferably injection-molded plastic parts that can be produced inexpensively on a large scale.
