 IMPROVEMENT IN PACKAGING FOR CAKE AND CAKE-FIXING METHOD

[1] INTRODUCTION - This descriptive report relates to a patent application for individual cake packaging and the like, for method of fixing the cake and the like to the individual packaging tray for ballerina used to apply coating on cakes and the like, for cake and the like packaged and for display packaging for cakes and the like packaged with individual packaging, belonging to the field of packaging, processes and equipment used in confectioneries, cake factories and the like, said individual packaging, method and ballerina received The arrangement for advantageously attaching the cake or the like to the tray of the individual package and the display package has been developed to provide better conditions for the storage, transport and display at the points of sale of the cakes or similar packed with the individual package.

 [2] BACKGROUND ART - The manufacture of cakes and the like on an industrial scale, carried out in the factory, confectionery and the like, is essentially comprised of the steps: dough preparation, shaping the dough appropriately, baking in a large oven capacity, remove the cake or similar from the oven, unmold, cover with grease, freeze, pack, where appropriate, refrigerate and transport to refrigerated body truck outlets.

[3] The usual individual packaging for cakes manufactured in The industrial truss usually comprises: a lower tray with lowered region relative to a projected peripheral band; a styrofoam base or plate PS that supports the plunger and is applied to the recessed region of the tray; an upper cover applied to the plunger resting on the baseplate and the tray; and a perimeter snap-in device with portions in the tray and lid that engage and secure each other, both tray and lid, made of vacuum-formed plastic.

[4] The coating operation preferably uses equipment called a ballerina, consisting of: a base; and by a turntable mounted on the base and on which the cake or the like to be covered is supported and equipment with nozzle for the coating mass. The coating operation with such packaging and equipment essentially comprises the steps of: placing the cake on a Styrofoam base plate, laying the cake and base plate on the ballerina plate, rotating the cake assembly mounted on the plate. base and apply the batter over the entire surface of the cake, remove the decorated cake set mounted on the ballerina's base plate and freeze. Thereafter, the frozen decorated cake assembly mounted on the Styrofoam baseplate is arranged in the packaging tray so that the baseplate fits into the recessed surface of the tray and the lid is applied over the frozen decorated cake arranged on the plate. base is fitted to the tray and said lid is secured to each other by the peripheral snapping device. The packaged cakes are stored in a cold room, they are removed, loaded in refrigerated truck bodies, distributors of the product. to the points of sale, where they are exposed by any means of exposure.

 [5] In the case of industrial scale production, a large quantity of packaged cakes are housed in the refrigerated truck, which is distributed to numerous points of sale. In these, the packaged cakes and the like are arranged in some display medium. This manufacturing, delivery and point-of-sale logistics is adequate, but some drawbacks can be noted.

 [6] Thus, if one or more units of packed cake, possibly at any time during manufacture and / or delivery, suffer more sudden movement or impact, the cake may move on the base plate fitted to the It often strikes the side of the lid, so that its cover in the impact region can be deformed and / or removed, rendering it useless for commercialization. This usually occurs with large quantities of packaged cake, representing high losses for the manufacturer.

 [7] Another problem with cakes and the like packaged in the above-mentioned tray and lid type packages is that, often, perhaps because of a low qualification of the workforce, the packaged cake, at some point in handling between The factory and point of sale is eventually laid upside down, causing the cake or similar to fall off the tray and fall against the lid, rendering it useless for commercialization.

[8] Another problem observed in cake manufacturing and distribution logistics relates to the conventional packaging of "vacuum forming", in which the fixing and loosening of the lid on the tray is made by a clamping device comprised of perimeter bends of suitable profiles, provided on the lid and tray, which are coupled together, providing interference closing. Thus, in the cake manufacturing line, for the closing of the package, the one who makes it has to handle the entire perimeter of the package to couple the folds. This may require inadequate time to the intended productivity of the manufacturing line, especially given that the operation is done with the packaging already containing the cake, which requires careful handling. Similar difficulties are noted by the end consumer of the product at the time of opening the package as it is required to handle the entire perimeter of the lid and tray to uncouple the folds that hold each other, remove the lid and gain access to the plunger.

[9] Another problem observed with the cake manufacturing and distribution logistics and the like is related to the storage at the place of manufacture, its transportation to the points of sale and the display of the cakes in them. On these occasions, a plurality of ready-made cakes packed in individual packages are stacked, forming several piles, which are stored in a cold room of the place of manufacture, transferred and stored in a cold room of a distribution truck and from this cold room said batteries are. moved to the point of sale display refrigerator. These batteries are relatively unstable due to inefficient support between packages. Thus, when handling these batteries, from the place of manufacture, through the truck of distribution and reaching the point of sale, these piles often suffer impacts or sudden movements that can affect them. Also, shake and / or maneuvering during transport by the refrigerated truck can also cause damage to piles of cakes packed in individual packages.

[10] Due to the possibility of compromising stacks of cake packed in individual packages during transport, such stacks have to be limited in height, resulting in under-utilization of the cold room of the delivery truck. This also results in injury to the cake maker.

[11] All of these disorders result in the loss of large quantities of the product to the detriment of the manufacturer and the end consumer. Because of this, there is an interest in overcoming these problems in the manufacture, individual packaging, storage, transportation, exposure and consumption of cakes and the like.

[12] OBJECTS OF THE INVENTION - The object of the present invention is to provide an individual pan and lid type cake package which overcomes the above-mentioned drawbacks of the prior art.

 [13] Another objective is to provide a second version of the individual packaging which aims to provide good cake packaging or the like, stability within the individual packaging and handling facilities in the cake or similar manufacturing line and to the end consumer;

 [14] Another objective is to provide packaging that in addition to meeting the above objective is simple construction and manufacturing.

[15] Another objective is to provide packaging that meets the objec- above and be of low cost.

 [16] Another objective is to provide a display package for a stack of cakes or the like packaged in the individual package which, in addition to wrapping the stack, also helps to overcome the above-mentioned prior art and other problems.

[17] Another objective is to provide a method of attaching the cake to the packaging tray.

 [18] Another objective is to provide improved ballerina equipment to perform the method.

 [19] BRIEF DESCRIPTION OF THE INVENTION - In view, therefore, of the above-mentioned problems and in order to overcome them and in order to meet the related objectives, the arrangement applied to packaging for cakes and the like, object of the present patent, has been developed. which is of a type obtained from vacuum-formed plastics and comprising: a tray receiving the cake; and a lid that is applied to the plunger and tray, both tray and lid, provided with peripheral portions of a locking device, whereby in the present arrangement the tray has the bearing surface of the plunger or the like projected relative to the peripheral insert and Said surface is provided with recessed regions in any shape, such as sparse points or continuous or discontinuous channels or recessed regions composed of channels and points or others, which are filled with cake coating mass, providing the formation of mechanical cake clamping device. or the like directly on the tray, according to the fastening method also object of the present invention, described below.

[20] The present invention also relates to a method of fixing of the cake in the tray of the package described above, comprising the fact that the said recessed regions of the tray, prior to the application of the cake on it, are filled, until spreading out, with cake coating mass, so that when If it is applied to the tray, its base rests on the coating mass and impregnation (penetration) of the cake base or similar with the coating mass occurs. Then the cake or similar set arranged on the tray is mounted on the ballerina, the coating is made, the covered cake set arranged on the tray is taken to the cold room and the cake or similar coated and the coating mass on which the cake rests. or the like and the impregnated coating mass on the base of the cake or the like is frozen and finally the lid is applied. When the cake cover and the points and / or segments of the coating mass disposed at its base and within the recessed regions of the tray, as well as the coating mass impregnated at the base of the cake or the like freeze and harden, a mechanical crimping occurs and consequent fixation of the plunger or similar on the tray, thereby completing the plunger or similar operation on the tray.

 [21] This mechanical crimping of the plunger on the tray provides clamping between parts that prevents the plunger from moving within the package, even when the assembly is abruptly moved or impacted, which can usually occur in manufacture and transportation and / or when By mistake the packaged cake is arranged upside down.

[22] This overcomes the above state of the art problem. observed in the transport of frozen packaged cakes between the place of manufacture and points of sale, thus meeting the main purpose of the arrangement.

 [23] Another advantage of the present packaging and method is the dispensing of the Styrofoam baseplate, which diminishes an item that is part of the product and any need for management of that item, such as purchase, storage and others.

 [24] Despite the facilities provided by the present packaging and method of use, it has a simple and low cost construction and fabrication meeting other disposal purposes.

[25] The present invention further comprises a second embodiment of the package comprising substantially: lower tray and frusto-conical lid both vacuum forming; and by an expanded polystyrene base disc which is supported by the tray and on which the plunger is arranged, and between the plunger and the base disc there is provided a mechanical crimping device of the type already described above, but perfected as described below; between the base disc and the lower tray there is provided a bayonet locking device; between the lower tray and the lid there is provided a quick closing device formed by bayonet fitting; and by handling tabs projected radially from the tray and lid; the lower face of the lower tray and the upper face of the lid incorporate a locking device to provide stable support for forming a stack of packages containing the cakes.

[26] The mechanical coupling device on the Styrofoam base disc, referred to above, is to provide the base disc or, optionally, Finally, the conical recess or trapezoidal section tray, which is filled until it spills out slightly, with a covering putty or other edible product on which the base of the cake is laid, which is then covered. by filling and coating dough, then the lid of the package is applied and the whole set frozen. This construction allows the plunger to be mechanically set into the base disc or tray.

 [27] Individual packaging with construction according to the second version, object of this patent, overcomes the problems of the state of the art. Thus, the attachment of the plunger to the base disc by the aforementioned mechanical crimping device provides perfect plunger stability in relation to the package, which prevents it from striking the inner surface of the plunger even when impacted or handled more frequently. intense.

 [28] On the other hand, attaching the base disc to the bottom tray by a bayonet fitting prevents the base disc bolt assembly from moving within the package.

[29] In addition, the quick closing device enables the lid to be applied to the tray without having to handle the entire perimeter of the package as with conventional cake packaging, thereby speeding closure on the cake manufacturing line. Also, the fact that the cake is perfectly stable in the lower tray as provided by the present packaging also favors faster closing, as handling can be done faster. All this overcomes the problems of the state of the art caused by the difficulty of conventional cake packaging, alluded to above.

[30] In addition, the quick closing device also facilitates and expedites the opening of the package to the end consumer of the product.

 [31] The locking device with portions provided on the bottom of the tray and on the top face of the lid ensures better support between packages arranged on top of each other, thus providing for the formation of taller and more stable piles of cakes packed with individual packages. of the present invention. This, coupled with the use of the display package containing a stack of cakes packed in individual packages, provides perfect stability and protection for the stack throughout its movement between the factory and retail outlets. In this way, the loss of cakes during transport by moving the cake within the individual package and / or compromising the stack of cakes packed in individual packages is virtually eliminated. On the other hand, the better stability and protection of the cake stack, provided by the individual and display packages, allows practically the entire space of the distribution refrigeration chamber to be used. All this favors the reduction of losses in the confection, storage, transport, distribution and exposure at the point of sale of the cakes or similar compared to the use of conventional packaging.

[32] The present invention also comprises a display package comprised of a vertical prismatic rectangular box sized to receive just a stack of cakes packed in the individual packages of the present invention; said fall xa has, on opposite side faces, respective handles and surrounding tear line, located at the level of the upper end of the individual lower package of the stack.

[33] Thus, at the point of sale, display packaging makes it easier and safer to move and display the stack of cakes packed in individual packages. All of this meets the main objectives of the present invention, which are to improve the movement of the cakes from the place of manufacture to the point of sale and to facilitate handling for the end consumer.

[34] In addition to these advantages, the present individual and display packaging present relatively simple construction and manufacture and low costs thus meeting other objects of the invention.

 [56] Optionally, the recessed region 11 has a continuous recessed circumferential channel shape of constant section 13 (fig. 3) formed in tray 2.

 [57] Optionally, the recessed region 11 has a discontinuous recessed circumferential channel shape formed by oblong channel portions 14.

 [58] Optionally, the recessed region 11 has the shape of the recessed circumferential channel formed by portions of alternating wider 15 and narrower 16 sectioned channels formed in tray 2.

 [59] The recessed regions 1 1, in any of their configurations: points 512, constant-section channel 13, discontinuous channel in the form of oblong channel portions 14, alternating wide-section 15 and narrow-channel channel 16 or otherwise, have cross-sections. - rectangular 17 (fig. 6A) composed of opposite walls 18 perpendicular to the surface of tray 2 and interconnected by bottom 19.

[60] Optionally, the section may be trapezoidal 20 (fig. 6B) with a smaller base in the plane of tray 2 and formed by opposite walls 21 oblique to the surface of tray 2 interconnected by bottom 22.

[61] Packaging 1 of such a construction provides a method of securing a plunger or the like 100 to a tray 2 (Figs. 7 to 10), carried out in the plating or similar step 100 preferably done with the aid of ballerina-type equipment 200, formed by support plate 201, rotatably mounted on a base 202 and receiving the plunger 100 and a dispensing nozzle 203 of the coating dough, equipment that is usual in factories, confectioners and others that make cakes.

 [62] Thus, the method is initially comprised in providing tray 2 and lid 3-type packaging 1 provided with locking parts 4 and tray 2 provided with the projected straight bearing support surface 5 incorporating the fastener. of the cake in tray 10 formed by the recessed regions 11 described above and said method further comprises the steps of:

 [63] 1 - Place tray 2 on ballerina support plate 201 (fig. 7) and fill the recessed regions 1 1 of tray 2 with cake batter 101 portions through nozzle 203 or the like. that they fill all of the lowered regions 11 and spread little out of them and lie on surfaces of tray 2 adjacent to such lowered regions 11;

[64] 2- Arrange the plunger 100 directly on the surface 5 of tray 2 (fig. 8) having its recessed regions 11 and surfaces adjacent to them filled and covered with portions of coating mass 101 such that base 102 of the the cake rests on such portions of coating 101 and they impregnate (penetrate) said base 102;

 [65] 3 - Carrying out the cake 100 coating operation 101 (fig. 9) by rotating the cake assembly 100 tray 2 with the aid of ballerina 200 and spreading the coating 101 over the cake 100 with the aid of the nozzle mass dispenser 203;

[66] 4 - Freeze the coated cake 100-101 disposed on the tray 2, whereby the portions of coating dough 101 contained in the recessed regions 11 tray 2 and adjacent surfaces thereon, on which the base 102 of the plunger 100 rests; and the impregnated (penetrated) coating mass 101 on said base 102 of plunger 100 also freezes, hardens and provides mechanical crimping and attachment of plunger 100 to tray 2 (fig. 10).

[67] Following such cake topping and panning operations in tray 2 are further cake making and dispensing operations, such as applying lid 3, storing in a cold room, and distributing to truck points of sale. refrigerators.

 [68] A coated cake assembly 100 packaged with package 1 of the present arrangement (Fig. 11) is therefore comprised of tray 2, coated cake 100-101 seated directly on tray 2 and fixed thereon by means of the plunger fastener in tray 10, subject to the present arrangement, and the lid 3 applied to the plated cake 100-101 and tray 2 and fixed thereto by the peripheral plug device 4. The plated cake 100-101 packaged in package 1, seated directly on tray 2 and secured therein by the clamping device 10 of the present arrangement, may be subjected to sudden movements or impacts during transport and / or inadvertently upside down without the bolt 100 move in tray 2 and tap lid 3, as is often the case with usual similar packaging.

[69] Ballerina-type equipment 200, used in conjunction with the present package 1 and which assists in carrying out the method as described above, has also been refined to adapt to said embodiment. Ballet 1. In this sense, the ballerina plate 201 has its upper support surface of tray 2 provided with recessed recesses 204 corresponding to the lowered and recessed regions of tray 2 and in which said recessed regions 11 and others are projected. on the underside of the tray 2, they engage to stabilize tray 2 on plate 201 during its rotation. The plate 201 is fitted in the space defined by the upper surface 5 and the recessed part 4 lowered relative to it of tray 2, which also favors its stabilization in the plate 201.
