Full Text | -2- COVER FOR ACCUMULATOR CONTAINERS BACKGROUND OF THE INVENTION The invention is about a cover for accumulator containers of the starter type, usually installed on motor vehicles. 5 It is known that, in the accumulators manufacture, proper containers are used, made of materials like, for example, synthetic resins based on polyvinyl chloride, polypropylene, celluloid, able to resist the action of an acid or a base, commonly called electrolyte, placed inside the container. A plurality of electrodes, consisting of metal plates, is disposed inside the 10 container and it is connected to the positive pole and the negative pole of a current generator. The container is closed at its upper opening by means of a cover that, in plan view, generally has a rectangular shape. This cover is provided with a plurality of through holes, through which the 15 electrolyte is introduced during the so called accumulator formation phase or during said accumulator recharge operation. The cover consists in practice of a main body, shaped according to the constructional and aesthetical requests of the customers. In fact, the need to customize the cover of the containers used in the 20 accumulators manufacture is more and more spread. The customers, to gain a competitive advantage towards the competitors in a technical field which has become overstocked in the last years, require the manufacturers to provide for covers which are as different as possible from the others at the point of sale or, for example, when they are offered to the main 25 car manufacturers. Therefore, the main inconvenience related to the manufacture of this component for accumulator containers is due to the fact that the manufacturers are obliged to carry out as many covers as the different requests of this sector's market are. 30 This involves the need to prepare proper manufacturin moulds for each single article, with the obvious disadvantages this means in terms of productive costs. Besides that, another inconvenience is due to the fact that, to meet the different customers demands, the manufacturer has to set up at any time a new and complete production, with the consequence that the manufacturing 35 and delivering times of the cover are inevitably prolonged. -2-A Not the least inconvenience is due to the fact that, if the manufacturer decides to maintain in stock even small quantities of different covers, he must manage a rather high number of codes, certainly greater than that generated by more standardized productions. 5 SUMMARY OF THE INVENTION The present invention intends to overcome the aforementioned inconveniences. In particular, the main object of the invention is to provide for a cover for accumulator containers which allows a higher productive standardization, 10 although supplying differentiated products to the market, able to meet the different customers needs. It is another object of the invention to reduce the costs related to the availability of moulds suitable for manufacturing any type of cover for accumulator containers. 15 It is a further object of the invention to reduce the manufacturing and delivering times of cover for accumulator containers, in order to satisfy in a quicker way the customers needs relative to the times allowed by the prior art. Said objects are obtained by a cover for containers suitable for being used in the accumulators manufacture which, according to the main claim, comprises a 20 main body for closing said container, provided with a plurality of first through holes for supplying the electrolyte, at which a shaped cap raised from the upper wall of said main body is formed, wherein said main body and said shaped cap are two separated pieces connected through joining means. Advantageously, the invention allows the manufacturer to meet the different 25 customers needs in a quicker way with respect to the prior art. More advantageously, the invention allows the manufacturers to customize the cover shape and colour according to the customers needs, without requiring to bear economic investments for manufacturing moulds dedicated for each execution. 30 Still advantageously, the invention provides for covers having rather appealing aesthetical features. Furthermore advantageously, with the invention, the costs related to the manufacture of covers for accumulator containers are reduced with respect to the prior art. 35 In fact, each manufacturing mould is composed by a first mould, of more -3- articulate design, common to the manufacture of each model, and a second less complicated mould, which is modified according to the customers requests and tastes.

DESCRIPTION OF THE INVENTION The cover of the invention is shown in FIG. 1, where it is generally indicated with numeral 1, applied to a container C used for carrying out accumulators installed, for instance, on motor vehicles. 30 One can see that the cover 1 comprises a main body 2 for closing the container C, provided with a plurality of not visible first through holes for supplying the electrolyte, being it an acid or a base, inside the container C. A shaped cap 3 is formed at the first through holes, being raised from the upper wall 2a of the main body 2. 35 According to the invention, the main body 2 and the shaped cap 3 are two -4- separated pieces connected through joining means, generally indicated with numeral 4. Moreover, on the main body 2 the positive and negative poles, generally indicated with numerals 13 and 14, are formed, used to perform the common 5 operations of accumulator charge and car electrical equipment connection. FIG8. 1, 2 and 3 show that the shaped cap 3 and the main body 2 comprise a common through hole 15 which, according to what is well known in this technical field, is used for positioning a feeler used to check the charge condition of the accumulator. 10 The cover 1 also comprises a handle 9, grasping which the user easily transports the container C. As evidenced in FiGs. 4 and 5, the joining means 4 comprise profiles, generally indicated with numeral 5, joined to the shaped cap 3, and opposite profiles, generally indicated with numeral 6, joined to the main body 2, which 15 are mutually snap coupled by pressure. More particularly, FIG. 4 shows that the profiles 5 consist of a plurality of caps 7 disposed on the lower wall 3a of the shaped cap 3. Preferably, the caps 7 form a single body with the shaped cap 3, since they are both obtained with a injection moulding process of plastic materials, but it is 20 evident that, in other executive embodiments, they could be coupled with the shaped cap through proper connection means. The opposite profiles 6 consist instead of the aforementioned first through holes, generally indicated with numeral 2b in FIG. 5, through which the electrolyte supply inside the container C takes place. 11 Therefore, the caps 7 are inserted in the through holes 2b to form the joining means 4 as a whole, when the shaped cap 3 is coupled with the main body 2. According to the preferred executive embodiment hereby described, the shaped cap 3 has a substantially T shaped plan outline 3' as shown in detail in FIGs, 1, 2 and 4. 30 Said cap is provided with a peripheral edge 3b, to be externally coupled with the perimeter of a raised edge 8, well visible in FIG. 5, and having a substantially T shaped plan outline 8' too, which is raised from the upper wall 2a of the main body 2. The first through holes 2b are obtained justatthe plane 16 delimited by the 35 raised edge 8 of the main body 2. -5- Still in FIG. 5 it is shown that the handle 9 is coupled with the main body 2 through joining means, generally indicated with numeral 10, preferably but not necessarily consisting of a through hole, not visible in the annexed drawings, obtained in each of the free ends 9a, 9b of the handle 9, in which a pin 11, 12 5 protruding from the raised edge 8 of the main body 2 is inserted. It is to be understood that, in other executive embodiments of the invention, the handle could be coupled with the main body through different fasteners but of known type per se. In further embodiments of the invention, said handle could be coupled with the 10 shaped cap instead of the main body to which said cap is then fixed. Another executive embodiment of the cover of the invention, generally indicated with numeral 100, is shown in FIG. 6, which is different from that previously described with reference to FIGs. 1 to 5 in that the joining means, generally indicated with numeral 103, comprise in this case a welding layer, 15 not visible in the drawings, made at walls, generally indicated with numeral 104 and visible in FIGs. 8 and 9 only, projecting from the lower wall 102a of the shaped cap 102 and from the upper wall 101a of the main body 101. It is evident that, in other executive embodiments of the invention, the welding layer which provides for the joining means could be made at the lower edge of 20 the shaped cap and at the upper edge of the main body. According to further executive embodiments of the invention, the joining means could comprise an adhesive layer made at the lower edge of the shaped cap and at the upper edge of the main body. Preferably but not necessarily, the joining means also 103 comprise profiles, 25 generally indicated with numeral 105, joined to the shaped cap 102, and opposite profiles, generally indicated with numeral 106, joined to the main body 101. Jusl the profiles 105 and the opposite profiles 106 define another substantial difference in the cover 100 with respect to the cover 1. 30 In fact, the profiles 105 still consist of a plurality of caps, generally indicated with numeral 107 in FIG. 6, but they are coupled with the upper wall 102a of the shaped cap 102 and thus they are externally visible. The caps 107 are inserted in the opposite profiles 106, which now consist not only of first through holes, generally indicated with numeral 101b, obtained in 35 the main body 101, butalsoofa plurality of second through holes, generally - 6 - indicated with numeral 102b, obtained in the shaped cap 102. The second through holes 102b define a longitudinal axis which substantially coincides with the longitudinal axis defined by the first through holes 101b. Therefore, the cover 100 of FIG. 6 allows the user to top up with water the 5 accumulator when the common maintenance operations have to be performed. On the other hand, the aesthetical effect provided by the cover of FIG. 1 is better, since it is lacking elements, like said caps, which interrupt the continuity of the visible surface and which have a merely technical purpose. it should be intended that, in further executive embodiments of the invention, in 10 which the shaped cap is still coupled with the main body through a welding layer, the caps could be disposed again on the lower wall of the shaped cap, providing for a combination of the embodiment of FIG, 1 with that of FIG. 6. According to the preferred executive embodiment hereby described, the welding layer consist of a heat seal but, in other embodiments, it could consist 15 of different but of known per se welding methods, for instance by ultrasounds. Another executive embodiment of the cover, generally indicated with numeral 200, is shown in FIG. 10, which is primarily different from those previously described for the particular shape of the shaped cap 202 supported by the main body 201, which is instead of the same shape. 20 Furthermore, in this case, the shaped cap 202 is composed by a first element 204, shown in the two views of FlGs. 11 and 12, which is disposed close to said main body 201, and by a second element 205, shown in FIG. 13, which is disposed to cover said first element 204. One can see that the profiles 206, consisting of the caps 207, are disposed on 25 the lower surface 204a of the first element 204, and thus they will be snap coupled with opposite profiles, not shown in the drawings, obtained in the main body 201. The joining means, generally indicated with numeral 203 and consisting of the usual welding layer, will be provided on the projecting walls 208 obtained on 30 the upper surface 204b of the first element 204 and on the corresponding projecting walls 208 obtained on the lower surface 205a of the second element 205. This constructional embodiment provides for a particularly high structural stability level of the shaped cap. 35 The projecting walls 208 of the first element 204 and the second element 205 -7- form the labyrinth along which the gases generated by the electrochemical processes which take place in each electrolytic cell during the accumulator charge are canalized, before being discharged to the outside through an outlet mouth 209 obtained on the second element 205. 5 As it is known, due to upsettings, rotations and overturnings of the accumulator, for example during its handling, part of the electrolytic liquid exits from the cells through the through holes of the main body 201. if the liquid discharged from the ceils reaches the outlet mouth 209, the efficiency condition of the accumulator could be at least partially compromised. 10 The function of the labyrinth is thus to prolong the path of the electrolyte outgoing from the cells, preventing it to reach the outlet mouth 209. This basic aspect, required by the market standards and by the rules on the matter, is connected to another undoubtedly important advantage achieved by the labyrinth of the cover 200 with respect to the embodiments described so 15 far, in particular that of FIGs. 8 and 9. In fact, in the latter executive embodiment, the coupling between the main body 101 and the shaped cap 102 takes place by welding or by gluing, generally performed at the corresponding projecting walls 104, after that the accumulator charge phase is finished. 20 However, as previously mentioned, since the electrolyte exits from the through holes 101b during the charge phase, before performing the welding process it is necessary to perfectly clean the upper surface of the main body 101 and to wait that said surface is well dry, otherwise it is impossible to carry out the operation or to perform it in a correct way. 25 On the contrary, with the embodiment of FIG, 10 and the subsequent ones, the cleaning of the upper surface of the main body 201 after the electrolyte topping up is no more needed, since said body and the shaped cap 202 are pressure- coupled. Here, the projecting walls 208 are disposed in the first element 204 and in the 30 second element 205, so that the gas discharging labyrinth is located inside the shaped cap 202 and no more between said cap and the main body, as it happens instead in the cover 100. The labyrinth communicates with the interior of the accumulator by means of the through holes obtained on the main body 201. 35 The welding or the gluing is performed on the projecting walls 208 of the first 8 204 and the second element 205, which are both integrally made of plastic material, and thus the shaped cap 202 is obtained. Said cap is then coupled with the main body 201 without performing any welding operation, that is by snap coupling the profiles 206 inside the opposite 5 profiles present in the main body 201. Therefore, the above described tricks or cleaning treatment of the upper surface of the main body 201 are no more needed. In conclusion, the embodiment of FIG. 10 has the considerable advantage of simplifying the application of the cover 200 to the container, allowing the 10 manufacturers, especially the accumulator factories, to reduce the accumulator manufacturing costs and times. Operatively, the manufacturer disposes the main body 2, 101 to close the container C and applies the handle 9,108 thereto, by the insertion of the pins, of the type indicated with numerals 11, 12 in FIG. 5, inside the through holes 15 obtained at the ends 9a, 9b and 108a, 108b of the corresponding handles 9, 108. Subsequently, the manufacturer externally couples the shaped cap 3, 102 with the main body 2,101, thus completing the preparation of the cover 1,100. On the contrary, the embodiment of FIG, 10 is different because it is required 20 at first to couple, by welding the corresponding projecting walls 208, the second element 205 with the first element 204 and thus to snap couple the first element 204 with the main body 201. Therefore, by the invention, the manufacturer could carry out the shaped cap with the specific shape and colour required by the customer, while the 25 underlying main body is produced in a standardized manner. He is thus able to customize the cover models, at the same time maintaining as uniform as possible the production, in particular of that component, more complex to manufacture, that is the main body, which is disposed to close the container. 30 So, he should merely modify the shaped cap mould, easier to manufacture, being able to meet each single customer's need anyhow. Consequently, the manufacturer reduces the costs related to the production of this kind of components, as well as the articles delivering lead time, in order to satisfy in a quicker way the needs of all the customers. 35 On the basis of the aforesaid description, it should be understood that the -9- cover of the invention achieves all the aforementioned objects and advantages. Modifications to the cover of the invention could be introduced in the executive stage, consisting for instance in a different shape of the shaped cap with 5 respect to those described and shown in the present description. Besides that, different executive embodiments of the invention could be introduced, in which the joining means are of different kind with respect to that previously described and shown, without impairing the advantage provided by the present patent. 10 All the described and cited, but not shown in the figures of the annexed drawings, embodiments, if they fall within the scope of protection of the following claims, should be intended as protected by the present patent. -10- WE CLAIM; 1) A cover (1; 100; 200) for containers (C) able to be used in the accumulators manufacture, comprising a main body (2; 101; 201) for closing said container (C), provided with a plurality of first through holes (2b; 101b) for 5 supplying the electrolyte, at which a shaped cap (3; 102; 202) raised from the upper wall (2a; 101a) of said main body (2; 101; 201) is formed, wherein said main body (2; 101; 201) and said shaped cap (3; 102; 202) are two separated pieces connected through joining means (4; 103; 203). 2} The cover (1; 100) as claimed in claim 1, wherein said joining 10 means (4; 103) comprise profiles (5; 105), joined to said shaped cap (3; 102), and opposite profiles (6; 106), joined to said main body (2; 101), which are mutually snap coupled by pressure. 3) The cover (100) as claimed in claim 1, wherein said joining means (103) comprise a welding layer, made at walls (104) projecting from said upper 15 wall (101a) of said main body (101) and from the lower wall (102a) of said shaped cap (102). 4) The cover as claimed in claim 1, wherein said joining means comprise a welding layer made at the lower edge of said shaped cap and at the upper edge of said main body. 20 5) The cover as claimed in claim 1, wherein said joining means comprise an adhesive layer made at the lower edge of said shaped cap and at the upper edge of said main body. 6) The cover (200) as claimed in claim 1, wherein said shaped cap (202) is composed by a first element (204), disposed close to said main body 25 (201), and by a second element (203), disposed to cover said first element (204). 7) The cover (200) as claimed in claim 6, wherein said joining means (203) comprise a welding layer, provided at walls (208) projecting from the upper surface (204b) of said first element (204) of said shaped cap (202) and 30 from the lower surface (205a) of said second element (205) of said shaped cap (202). 8) The cover (1) as claimed in claim 2, wherein said profiles (5) consist of a plurality of caps (7), disposed on the lower wall (3a) of said shaped cap (3). 35 9) The cover (100) as claimed in claim 2, wherein said -11- profiles (105) consist of a plurality of caps (107) which are externally coupled with the upper wall (102a) of said shaped cap (102). 10) The cover (200) as claimed in claim 6, wherein said profiles (206) consist of a plurality of caps (207) disposed on the lower surface (204a) of said 5 first element (204) of said shaped cap (202). 11) The cover (1) as claimed in claim 8, wherein said opposite profiles (6) consist of said first through holes (2b), inside which said caps (7) are inserted. 12) The cover (100) as claimed in claim 9, wherein said opposite 10 profiles (106) consist of said first through holes (101b) and of a plurality of second through holes (102b), obtained in said shaped cap (102), which define a longitudinal axis which substantially coincides with the longitudinal axis defined by said first through holes (101b) obtained in said main body (101), said caps (107) being inserted in said first (101b) and said second (102b) 15 through holes. 13) The cover (100; 200) as claimed in claim 3, wherein said welding layer consist of a heat seal. 14) The cover (1; 100; 200) as claimed in claim 1, wherein said shaped cap (3; 102; 202) has a substantially T shaped plan 20 outline (31). 15) The cover (1; 100; 200) as claimed in claim 1, wherein said shaped cap (3; 102; 202) is provided with a peripheral edge (3b) which is externally coupled with the perimeter of a raised edge (8, 108) which is raised from said upper wall (2a; 101a) of said main body (2; 101; 201). 25 16) The cover (1; 100; 200) as claimed in claim 15, wherein said raised edge (8) has a substantially T shaped plan outline (8'). 17) The cover (1; 100; 200) as claimed in claim 15, wherein said first through holes (2b; 101b) are obtained in said raised edge (8). 18) The cover (1; 100; 200) as claimed in claim 15, wherein it 30 comprises a handle (9; 108) coupled with said main body (2; 101; 201) through joining means (10). 19) The cover as claimed in claim 1, wherein it comprises a handle coupled with said main body through fastening means. 20) The cover (1; 100; 200) as claimed in claim 18, wherein said 35 joining means (10) consist of a pin (11, 12) protruding from said 12 raised edge (8), inserted in a through hole obtained in each of the free ends (9a, 9b; 108a, 108b) of said handle (9; 108). 21) The cover according to what substantially described and shown.
