[0055] The following describes the specific implementation of the present invention in more detail with reference to specific embodiments:

[0056] Please refer to Figure 1 , an embodiment of the present invention provides a decorative housing 100, which includes a decorative layer 110, an intermediate layer 120, and a base material layer 130 arranged in sequence. The side of the decorative layer 110 facing the intermediate layer 120 is closely attached to the side of the intermediate layer 120 facing the decorative layer 110, and the side of the intermediate layer 120 facing the base material layer 130 is closely attached to the side of the base material layer 130 facing the intermediate layer 120. Among them, the base material layer 130 is used to connect with or accommodate the product body, has a certain strength, and the decorative layer 110 can at least improve the aesthetics and has a certain flexibility.

[0057] The decorative housing 100 provided by the embodiment of the present invention can make the decorative layer 110 adaptively expand and deform under the influence of the intermediate layer 120 and the base material layer 130 even when there are corners on the base material layer 130 through the base material layer 130, the intermediate layer 120 and the decorative layer 110 that are tightly attached in sequence, and thus can basically completely cover one side of the base material layer 130. Based on this, the production efficiency of the decorative housing 100 can be relatively high, and it is beneficial to ensure and improve the overall aesthetics of the decorative housing 100; and the bonding areas between the base material layer 130, the intermediate layer 120 and the decorative layer 110 in sequence are sufficient and the combination is tight, so as to effectively reduce the risk of the decorative layer 110 peeling off relative to the base material layer 130.

[0058] Please refer to Figure 1 , in this embodiment, the decorative layer 110 is cloth and / or leather.

[0059] By adopting the above scheme, the decorative layer 110 can have better aesthetics and certain wear resistance, and also has better flexibility, so as to ensure that the decorative layer 110 can adaptively expand and deform under the influence of the intermediate layer 120 and the base material layer 130 even when there are corners on the base material layer 130, thereby ensuring and improving the use performance of the decorative layer 110.

[0060] In other possible implementation manners, the decorative layer 110 can also be wood chips. With such a setting, the decorative layer 110 can also have better aesthetics and certain wear resistance.

[0061] Please refer to Figure 1 , in this embodiment, the intermediate layer 120 is attached to the decorative layer 110 and / or the base material layer 130 by hot pressing and / or injection molding.

[0062] By adopting the above scheme, at least part of the intermediate layer 120 can be formed on one side of the decorative layer 110 through the hot pressing process and / or the injection molding process. At the same time, at least part of the side surface of the intermediate layer 120 facing the decorative layer 110 can be in close contact with the side surface of the decorative layer 110 facing the intermediate layer 120, so as to ensure and improve the bonding tightness between the decorative layer 110 and the intermediate layer 120, and further reduce the risk of separation and peeling between the decorative layer 110 and the intermediate layer 120; or, the intermediate layer 120 can be formed between the decorative layer 110 and the base material layer 130 through the injection molding process. At the same time, the opposite sides of the intermediate layer 120 will be in close contact with the decorative layer 110 and the base material layer 130 respectively, so as to ensure and improve the bonding tightness between the decorative layer 110 and the intermediate layer 120 and between the intermediate layer 120 and the base material layer 130, and further reduce the risk of separation and peeling between the decorative layer 110 and the intermediate layer 120, and further reduce the risk of separation and peeling between the intermediate layer 120 and the base material layer 130.

[0063] By adopting the above solution, the processing convenience and production efficiency of the decorative housing 100 can also be effectively improved to a certain extent.

[0064] Please refer to Figure 1 , in this embodiment, the base material layer 130 is formed by hot pressing and / or injection molding.

[0065] By adopting the above solution, the forming efficiency and forming precision of the base material layer 130 can be improved, so that the processing convenience and production efficiency of the decorative housing 100 can be effectively improved to a certain extent.

[0066] By adopting the above solution, the base material layer 130 can also be formed on one side of the intermediate layer 120 through a hot pressing process and / or an injection molding process. At the same time, the side surface of the base material layer 130 facing the intermediate layer 120 will be in close contact with the side surface of the intermediate layer 120 facing the base material layer 130, so that the bonding tightness between the intermediate layer 120 and the base material layer 130 can be guaranteed and improved, and further the risk of separation and peeling between the intermediate layer 120 and the base material layer 130 can be reduced.

[0067] Please refer to Figure 2 , in this embodiment, the intermediate layer 120 includes at least one sub-intermediate layer 121, and at least one sub-intermediate layer 121 is any one of a plastic layer, a rubber layer, and a silicone layer.

[0068] By adopting the above solution, the intermediate layer 120 can form a single-layer or multi-layer structure. Among them, at least one sub-intermediate layer 121 needs to be a plastic layer, a rubber layer, or a silicone layer. Based on this, it can be ensured that the intermediate layer 120 can be formed by hot pressing and / or injection molding and can be in close contact with the decorative layer 110 and the base material layer 130.

[0069] Please refer to Figure 2 , in this embodiment, the intermediate layer 120 includes at least two sub-intermediate layers 121, and the adjacent two sub-intermediate layers 121 are in close contact with each other. The sub-intermediate layer 121 is any one of a plastic layer, a rubber layer, a silicone layer, a touch screen, and a flexible circuit board, and at least one sub-intermediate layer 121 is any one of a plastic layer, a rubber layer, and a silicone layer. The number of layers of the sub-intermediate layer 121 is greater than or equal to the number of material types of the sub-intermediate layer 121.

[0070] It should be noted here that the material types of the sub-intermediate layers 121 can be partially the same or all different.

[0071] Among them, if each sub-intermediate layer 121 is any one of a plastic layer, a rubber layer, and a silicone layer, the sub-intermediate layer 121 can be formed by a hot pressing process and / or an injection molding process. Based on this, the processing of the intermediate layer 120 can be facilitated, the production efficiency can be improved, and at the same time, the bonding strength between the outermost sub-intermediate layer 121 and the decorative layer 110 and / or the substrate layer 130 can be ensured and improved, and the bonding strength between adjacent sub-intermediate layers 121 can be ensured and improved. As a result, the risk of delamination of the decorative housing 100 can be further reduced, the service performance of the decorative housing 100 can be further ensured, and the service life of the decorative housing 100 can be extended.

[0072] Among them, on the basis of ensuring that at least one sub-intermediate layer 121 is any one of a plastic layer, a rubber layer, and a silicone layer, the sub-intermediate layer 121 can also be a touch screen or a flexible circuit board. The touch screen or the flexible circuit board can be at least partially embedded in the plastic layer, the rubber layer, or the silicone layer to realize the relatively fixed bonding of the layers of the intermediate layer 120 together. Among them, the touch screen can endow the intermediate layer 120 with touch characteristics, so that the decorative housing 100 can be suitable for touch products. The setting of the flexible circuit board can realize the pre-layout of the circuit in the intermediate layer 120, so that the intermediate layer 120 can realize special functions such as temperature sensing and voice control, thereby improving the service performance of the decorative housing 100 and facilitating the cooperation with the product.

[0073] Please refer to Figure 2, in this embodiment, the sub-intermediate layer 121 is any one of a pressure-sensitive adhesive layer, a PU (Polyurethane) layer, a PP (Polypropylene) layer, a PA (Polyamide) layer, a PC (Polycarbonate) layer, a PS (Polystyrene plastic) layer, a nylon layer, a nylon 6 layer, an ABS (Acrylonitrile Butadiene Styrene plastic) layer, a PBT (polybutylene terephthalate) layer, a PVC (Polyvinyl chloride) layer, an EVA (ethylene-vinyl acetate copolymer) layer, a TPE (Thermoplastic Elastomer) layer, a TPU (Thermoplastic polyurethanes) layer, a TPR (Thermo-Plastic-Rubber material) layer, a TPV (Thermoplastic Vulcanizate) layer, a CPE (Chlorinated Polyethylene) layer, an SIS (thermoplastic elastomer) layer, a TPO (polyolefin thermoplastic elastomer) layer, a PPE (Polypheylene ether) layer, a POM (Paraformaldehyde) layer, an SBS (Styreneic Block Copolymers) layer, an SEBS (hydrogenated styrene-butadiene block copolymer) layer, a TPEE (thermoplastic polyester elastomer) layer, a SILICONE (organosilicon plastic) layer, and a film.

[0074] By adopting the above solution, on the basis of ensuring the tight fit between the intermediate layer 120 and the decorative layer 110 and the substrate layer 130, through the selection of different materials for each sub-intermediate layer 121, the intermediate layer 120 can integrate the material properties and have special and applicable use properties.

[0075] Please refer to Figure 3 , in this embodiment, the substrate layer 130 includes at least one sub-substrate layer 131, and the sub-substrate layer 131 is any one of a silicone layer, a rubber layer, and a plastic layer.

[0076] It should be noted here that when at least one sub-substrate layer 131 of the substrate layer 130 is made of silica gel, the substrate layer 130 can have high mechanical strength, good thermal stability and stable chemical properties, and can be precisely shaped as needed, thereby ensuring and improving the performance of the decorative housing 100 and extending the service life of the decorative housing 100.

[0077] When at least one sub-substrate layer 131 of the substrate layer 130 is made of rubber, the substrate layer 130 can have excellent elasticity and can be precisely shaped as needed, thereby ensuring and improving the performance of the decorative housing 100 and extending the service life of the decorative housing 100.

[0078] When at least one sub-substrate layer 131 of the substrate layer 130 is made of plastic, the substrate layer 130 can have appropriate stiffness, hardness and mechanical properties, and can be precisely shaped as needed, thereby ensuring and improving the performance of the decorative housing 100 and extending the service life of the decorative housing 100. In addition, the aesthetics of the decorative housing 100 can be optimized by coloring the plastic.

[0079] Please refer to Figure 3 , in this embodiment, the substrate layer 130 includes at least two sub-substrate layers 131, and the sub-substrate layer 131 is any one of a silica gel layer, a rubber layer and a plastic layer. Each sub-substrate layer 131 is sequentially formed by hot pressing and / or injection molding, and the adjacent two sub-substrate layers 131 are closely attached.

[0080] It should be noted here that the sub-substrate layer 131 can be formed layer by layer through a hot pressing process and / or an injection molding process. Based on this, the processing of the substrate layer 130 can be facilitated, the production efficiency can be improved, and at the same time, the bonding strength between the outermost sub-substrate layer 131 and the intermediate layer 120 can be ensured and improved, as well as the bonding strength between adjacent sub-substrate layers 131 can be ensured and improved. Thereby, the risk of delamination of the decorative housing 100 can be further reduced, the performance of the decorative housing 100 can be further ensured, and the service life of the decorative housing 100 can be extended.

[0081] Please refer to Figure 4 , in this embodiment, a functional hole 101 is provided on the decorative housing 100, and the functional hole 101 penetrates at least a part of the substrate layer 130.

[0082] It should be noted here that when the product has functional components such as a camera, a lamp, a plug-in hole, etc. that need to communicate with the outside, and the installation position of the functional component is opposite to the installation position of the decorative housing 100, a functional hole 101 can be correspondingly provided on the decorative housing 100 to ensure the realization of the function of the functional component. Thereby, the performance of the decorative housing 100 can be ensured.

[0083] Please refer to Figure 1, in this embodiment, the intermediate layer 120 is made of a low-temperature thermocompression molding material or a low-temperature injection molding material.

[0084] By adopting the above solution, during the molding process of the intermediate layer 120, the risk of damage to the decorative layer 110 in contact with the intermediate layer 120 due to the too high molding temperature of the intermediate layer 120 can be effectively reduced, thereby ensuring the service performance of the decorative housing 100.

[0085] Of course, the molding time of the intermediate layer 120 can also be compressed by compressing the thickness of the intermediate layer 120, so as to reduce the risk of damage to the decorative layer 110 in contact with the intermediate layer 120 due to the too long molding time of the intermediate layer 120, thereby ensuring the service performance of the decorative housing 100.

[0086] Please refer to Figure 1 , in this embodiment, the decorative housing 100 is any one of a watch band, a watch case, a speaker housing, a headphone case, a VR glasses case, an AR glasses case, an air purifier housing, a game controller housing, an atmosphere lamp shade, a mouse housing, a keyboard housing, a computer housing, an automotive interior, a pen barrel, a smart switch, a wireless charger housing, a camera housing, a beauty device housing, a massager housing, an e-cigarette rod, a packaging box, a toy housing.

[0087] By adopting the above solution, the aesthetics of the outer side / outer packaging of the corresponding product can be optimized through the decorative housing 100.

[0088] Please refer to Figure 4 , in this embodiment, the decorative housing 100 is a mobile phone case integrally formed or detachably connected to a mobile phone, or the decorative housing 100 is a tablet case integrally formed or detachably connected to a tablet; several mounting positions for mounting electronic components are provided on one side of the decorative housing 100 with respect to the base material layer 130, and a first functional hole that penetrates through and is used for accommodating a camera is further provided on the decorative housing 100.

[0089] By adopting the above solution, the electronic components inside the mobile phone can be dust-proofed and protected through the mobile phone case, and the mobile phone has better aesthetics; the electronic components can be limited and installed through the mounting positions on the inner side of the base material layer 130, which is convenient for the processing of the mobile phone, is conducive to improving the space utilization rate, and is conducive to the miniaturization design of the mobile phone; and the camera inside the mobile phone can also obtain external information through the first functional hole that penetrates through the base material layer 130, the intermediate layer 120 and the decorative layer 110. Thus, the service performance of the mobile phone using the decorative housing 100 can be optimized.

[0090] Similarly, by adopting the above solution, the electronic components inside the tablet can be dust-proofed and protected by the tablet case, and the tablet can have better aesthetics; the electronic components can be installed in a limited manner through the installation positions inside the base material layer 130, which is convenient for the processing of the tablet, helps to improve the space utilization rate, and is conducive to the miniaturization design of the tablet; and the first functional holes penetrating through the base material layer 130, the intermediate layer 120, and the decorative layer 110 can also facilitate the camera inside the tablet to obtain external information through the first functional holes. Therefore, the performance of the tablet using the decorative case 100 can be optimized.

[0091] Please refer to Figure 4 , in this embodiment, the decorative case 100 is a protective cover. The decorative case 100 at least partially wraps the electronic product and is adapted to the electronic product. The decorative case 100 is provided with a through second functional hole at the position corresponding to the lens of the electronic product, a through third functional hole at the position corresponding to the function button of the electronic product, and a through fourth functional hole at the position corresponding to the plug hole of the electronic product.

[0092] By adopting the above solution, a protective cover for electronic products such as mobile phones and tablets can be formed by the decorative case 100, which is more beautiful, and the electronic products such as mobile phones and tablets can be protected, and the risk of damage to the electronic products such as mobile phones and tablets due to dropping and other reasons can be effectively reduced.

[0109] Please refer to Figure 1 , an embodiment of the present invention further provides a molding process for producing the decorative housing 100, including the following steps:

[0110] Prepare the decorative layer 110: Set the decorative layer 110 and position the decorative layer 110;

[0111] Prepare the intermediate layer 120: Mold the intermediate layer 120 on one side of the decorative layer 110 by hot pressing and / or injection molding, and make the intermediate layer 120 closely adhere to the decorative layer 110;

[0112] Prepare the base material layer 130: Mold the base material layer 130 on the side of the intermediate layer 120 away from the decorative layer 110 by hot pressing and / or injection molding, and make the base material layer 130 closely adhere to the intermediate layer 120.

[0113] It should be noted here that the processing flow of the decorative housing 100 is specifically as follows: First, place the decorative layer 110, and then, on the basis of positioning the decorative layer 110, mold the intermediate layer 120 by hot pressing and / or injection molding. During the molding of the intermediate layer 120, the intermediate layer 120 will closely adhere to the decorative layer 110. At the same time, the decorative layer 110 will also adaptively expand and deform under the influence of the intermediate layer 120 to form a wrapping effect; Finally, mold the base material layer 130 on the other side of the intermediate layer 120. During the molding of the base material layer 130, the base material layer 130 will closely adhere to the intermediate layer 120. At the same time, the decorative layer 110 will further adaptively expand and deform, so that the decorative layer 110 can basically completely wrap one side of the base material layer 130 even when there are corners on the base material layer 130.

[0114] Therefore, by adopting the above solution, the decorative housing 100 can be produced by layer-by-layer molding through hot pressing and / or injection molding, and the production efficiency is relatively high; moreover, the combination between layers of the processed decorative housing 100 is very tight, and the decorative housing 100 is not prone to delamination, which can make the service performance of the decorative housing 100 relatively high and the service life relatively long; this molding process can be applied even to the decorative housing 100 with corners, and the applicable range is relatively wide.

[0115] Please refer to Figure 5 , Figure 6 , Figure 7 , in this embodiment, the steps of preparing the decorative layer 110, preparing the intermediate layer 120, and preparing the base material layer 130 are all carried out on the same lower mold 220.

[0116] It should be noted here that in the step of preparing the decorative layer 110, the decorative layer 110 is set on the lower half mold 220, and the decorative layer 110 is positioned relative to the lower half mold 220; subsequently, in the steps of preparing the intermediate layer 120 and the substrate layer 130, the relative position of the decorative layer 110 relative to the lower half mold 220 is maintained unchanged, and the intermediate layer 120 and the substrate layer 130 are formed layer by layer by hot pressing and / or injection molding.

[0117] Therefore, by adopting the above solution, during the layer-by-layer forming process, the relative position of the decorative layer 110 or the semi-formed decorative layer 110 and the intermediate layer 120 relative to the lower half mold 220 can be maintained unchanged. Based on this, it is beneficial to ensure the accuracy of the relative positions of each process during the forming of the decorative housing 100, reduce the number of repositioning times, and thus can significantly reduce the position deviation caused by multiple repositioning, thereby significantly improving the processing accuracy of the formed decorative housing 100 and increasing the production yield.

[0118] Please refer to Figure 5 、 Figure 6 、 Figure 7 In this embodiment, the steps of preparing the decorative layer 110, the intermediate layer 120, and the substrate layer 130 are carried out on a multi-station forming machine 200.

[0119] Among them, the multi-station forming machine 200 is provided with a turntable 210. The turntable 210 can be used to install at least one lower half mold 220, and the turntable 210 can drive each lower half mold 220 to pass through at least two forming stations 201 in sequence.

[0120] Among them, the multi-station forming machine 200 is provided with different upper half molds (not shown in the figure) at each forming station 201. When the lower half mold 220 moves to each forming station 201, the upper half mold corresponding to the forming station 201 can be clamped with the lower half mold 220 to form the intermediate layer 120 or the substrate layer 130.

[0121] It should be noted here that when the intermediate layer 120 only includes one sub-intermediate layer 121 and the substrate layer 130 also only includes one sub-substrate layer 131, the multi-station forming machine 200 can be provided with only two forming stations 201.

[0122] Among them, at the first forming station 201, the upper half mold corresponding to the first forming station 201 can be clamped with the lower half mold 220 to form the intermediate layer 120 by hot pressing and / or injection molding, that is, the step of preparing the intermediate layer 120 is carried out. And at the second forming station 201, the upper half mold corresponding to the second forming station 201 can be clamped with the lower half mold 220 to form the substrate layer 130 by hot pressing and / or injection molding, that is, the step of preparing the substrate layer 130 is carried out.

[0123] It should also be noted here that when the intermediate layer 120 includes at least two sub-intermediate layers 121, and / or the base material layer 130 includes at least two sub-base material layers 131, and / or an insert needs to be provided in the intermediate layer 120, and / or an insert needs to be provided in the base material layer 130, the multi-station molding machine 200 can be provided with at least three molding stations 201 according to the setting, and different processes can be performed at each molding station 201.

[0124] Therefore, by adopting the above solution, the lower half mold 220 can be driven by the turntable 210 to switch between different molding stations 201 and be clamped with different upper half molds to perform different processes, and finally the production of the decorative housing 100 can be completed on one multi-station molding machine 200. Based on this, the transfer of semi-finished products and the mold change time can be reduced, thereby significantly improving the production efficiency. Moreover, the molding parameters of the same multi-station molding machine 200 are relatively stable, which can significantly improve the stability and accuracy during the molding of the decorative housing 100, thereby improving the production yield.

[0125] Please refer to Figure 5 、 Figure 6 、 Figure 7 In this embodiment, the multi-station molding machine 200 is further provided with a cooling system 230 for cooling each lower half mold 220. The cooling system 230 includes a plurality of liquid inlet pipes and liquid outlet pipes communicated with the lower half mold 220. Optionally, the coolant flowing in the liquid inlet pipes and liquid outlet pipes can be but is not limited to water.

[0126] By adopting the above solution, during the process of layer-by-layer forming the intermediate layer 120 and the base material layer 130 by hot pressing and / or injection molding, the lower half mold 220 can be cooled by circulating the coolant along the liquid inlet pipes and liquid outlet pipes through the lower half mold 220. Based on this, the temperature borne by the decorative layer 110 can be ensured not to be too high, thereby reducing the risk of damage to the decorative layer 110 due to excessive temperature, that is, the integrity of the decorative layer 110 can be ensured and the service performance of the decorative layer 110 can be ensured.

[0127] Please refer to Figure 1 This embodiment of the present invention also provides a molding process for producing the decorative housing 100, including the following steps:

[0128] Prepare the base material layer 130: The base material layer 130 is formed by hot pressing and / or injection molding, wherein a plurality of support portions (not shown in the figure) protrude from one side of the base material layer 130;

[0129] Prepare the decorative layer 110: The decorative layer 110 is disposed on each support portion and the decorative layer 110 is positioned, wherein an interval space can be jointly enclosed among the decorative layer 110, each support portion and the base material layer 130;

[0130] Preparing the intermediate layer 120: The intermediate layer 120 is injection molded within the spaced-apart space, and both sides of the intermediate layer 120 are closely attached to the decorative layer 110 and the substrate layer 130 respectively.

[0131] Here, it should be noted that the processing flow of the decorative housing 100 is specifically as follows: First, the substrate layer 130 is formed by hot pressing and / or injection molding. The subsequent surface of the formed substrate layer 130 that faces the decorative layer 110 is convexly provided with a plurality of support portions, and the spaced-apart spaces formed between the support portions communicate with each other; Subsequently, the decorative layer 110 is placed on one side of the substrate layer 130 provided with the support portions. At this time, each support portion can support the decorative layer 110, and an spaced-apart space communicating with the outside is formed among the decorative layer 110, each support portion, and the substrate layer 130; Finally, injection molding is carried out into the spaced-apart space to form the intermediate layer 120. During the molding of the intermediate layer 120, the intermediate layer 120 will be closely attached to the decorative layer 110 and the substrate layer 130 simultaneously. At the same time, the decorative layer 110 will also adaptively expand and deform under the influence of the intermediate layer 120 to form a covering effect.

[0132] Therefore, by adopting the above solution, the decorative housing 100 can be produced with relatively high precision and high production efficiency; and the combination between the decorative layer 110, the intermediate layer 120, and the substrate layer 130 of the processed decorative housing 100 is very tight in sequence, so that the decorative housing 100 is not prone to delamination, and the decorative housing 100 has high service performance and long service life; and this molding process can be applied even to the decorative housing 100 with corners, and has a wide application range.

[0133] In addition, the above steps of preparing the substrate layer 130, preparing the decorative layer 110, and preparing the intermediate layer 120 can also be carried out in one stop on the multi-station molding machine 200.

[0134] Differently, when the substrate layer 130 only includes one sub-substrate layer 131 and the multi-station molding machine 200 is provided with two molding stations 201, at the first molding station 201, the upper half mold corresponding to the first molding station 201 can be closed with the lower half mold 220 to hot press and / or injection mold the substrate layer 130, that is, to carry out the step of preparing the substrate layer 130; while at the second molding station 201, the upper half mold corresponding to the second molding station 201 can be closed with the lower half mold 220 to hot press and / or injection mold the intermediate layer 120, that is, to carry out the step of preparing the intermediate layer 120.

[0135] Based on this, the lower mold 220 can also be driven by the turntable 210 to switch between different molding stations 201 and be clamped with different upper molds to perform different processes. Finally, the production of the decorative shell 100 is completed on a multi-station molding machine 200. Based on this, the transfer of semi-finished products and the mold change time can be reduced, thereby significantly improving the production efficiency. Moreover, the molding parameters of the same multi-station molding machine 200 are relatively stable, which can significantly improve the stability and accuracy during the molding of the decorative shell 100, thus improving the production yield.

[0136] Exemplarily, the above multi-station molding machine 200 can use a multi-station injection molding machine with the Chinese patent publication number CN105479658B or a multi-color injection molding machine with the Chinese patent publication number CN206085483U to complete two or three molding operations in one stop, enabling the decorative layer 110, the intermediate layer 120, and the substrate layer 130 to be molded in one stop. Based on this, not only is the structure of the obtained decorative shell 100 more compact, but also the production efficiency and molding accuracy of the decorative shell 100 can be ensured.

[0137] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, or improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
