Definitions
- the invention relates to a spray can, which is ergonomically designed to ensure a secure hold of the can when spraying, according to the type specified in the preamble of claim 1 and to a device for producing the spray can according to the type mentioned in the preamble of claim 11 and on a method for producing the spray can with said device according to the kind mentioned in the preamble of claim 13.
- Spray cans of this type are used in a wide variety of different ingredients, such as. B. deodorants, hairspray, shaving foam, lacquers or paints, oils, etc.
- the use of these spray cans is usually made more difficult by the fact that the fingers, which surround the cylindrical can body, do not offer sufficient hold of the can when the spray button is pressed.
- This problem cannot be easily remedied by the known solutions that are used in PET beverage bottles. With these PET bottles, additional recessed handles or recesses are attached to the jacket body of the bottle for a better hold.
- the other requirements that are placed on a PET bottle are completely different from those on a spray can that is under high pressure and contains aggressive agents. These differences can be clearly seen in the selected material and in the manufacturing process, so that new solutions have to be found for the spray can.
- spray cans are now a mass product that can only be economically produced in large quantities. That is why there are specially developed production lines on which an optimized manufacturing process takes place. This manufacturing process is so technically optimized that hardly Changes in the production of spray cans are possible without incurring additional costs. If the shape is to be modified from the known spray cans, this generally means drastic effects on the entire manufacturing process, since either an additional manufacturing process has to run on the existing machines or additional or new machines are required.
- a spray can of the type mentioned is known from utility model DE 299 10 184 U1, which has a circumferential recessed grip in the can body, which is approximately 3-4 cm from the can opening. This prevents the spray can from sliding through the fingers when the spray button is pressed, but the entire position of the spray can in the hand is quite cumbersome and unnatural. The can also becomes more difficult to hold with increasing diameter of the can body.
- the strong heel, which results from the lower recessed grip and the higher can wall, is a major disadvantage for the safety of the spray can, since the material of the spray can wall is greatly weakened in this area.
- the known spray cans from the publication DE 299 10 184 Ul, are manufactured by the optimized manufacturing process described below. First, so-called pellets or blanks are punched out of a sheet for the further process. These pellets or blanks are formed into a cylindrical hollow body by a deep-drawing process. As a rule, the process of backward hollow pressing is used. After the cylindrical hollow body has been manufactured, it is painted from the inside so that the spray can chemically withstands the aggressive ingredients and propellant gases. The cylindrical hollow body is also printed or painted from the outside. For printing from the outside, it is important to have a rotationally symmetrical object. For this reason, deformations can only be carried out after the cylindrical hollow body has been printed.
- the applied layers of paint also serve as lubricants for the subsequent deformation steps.
- the upper edge of the cylindrical Hollow body cleanly separated to ensure an exact shape for the can opening with the collar.
- the upper area of the can is formed from the cylindrical hollow body with the shoulder and with the can opening and collar. This deformation usually occurs through several manufacturing steps in a press. In this press, the cylindrical hollow bodies are made into a finished spray can without a spray system. The individual spray cans are then tied together to form a bundle and prepared for removal. Another company is usually responsible for filling the spray cans and attaching the spray systems.
- the invention is therefore based on the one hand the task of developing an easy-to-use spray can of the type mentioned in the preamble of claim 1, which is ergonomically shaped and nevertheless does not represent a safety disadvantage. This is achieved according to the invention by the measures specified in the characterizing part of claim 1, which have the following special significance.
- the spray can - in contrast to the known spray cans from the prior art - has an additional shaping area in the upper can section, which can extend over the entire shoulder area of the spray can.
- this shaping area the cross section of the spray can is configured differently from the almost circular cross section of the lower can section. This means that the different cross sections over the longitudinal extent of the spray can generally do not have a circular cross section, as in the lower can section.
- This shaping area runs seamlessly, as long as it extends over the shoulder area, into the standardized can opening. Consequently, with the spray cans according to the invention which have a standardized can opening, standardized spray systems can also be used, even if they have no cylindrical body in the shaping area.
- the spray can advantageously has a substantially constant wall thickness over the circumference of the cross section and over its height (longitudinal extension), ie the wall thickness is constant in radial and axial extension. This ensures, above all, a high level of safety for filled spray cans that are under high pressure.
- the object of the invention is, on the other hand, to show a device of the type mentioned at the outset so that the manufacture of the spray can can be ensured without significant changes in a conventional but modified manufacturing process. This is achieved according to the invention by the measures specified in the characterizing part of claim 11, which have the following special meaning.
- the matrices of the device that are used to form the upper can section are designed in accordance with the invention in such a way that the shape of the spray can can also be formed by their selected contours.
- the matrices in the various cross sections in the shaping area have circumferences of the contours that are not circular.
- the geometrically changed contours of the dies in the molding process of the upper can section also cause the shaping area to be reshaped.
- the invention is also based on the object of developing a modified method of the type already mentioned in order to economically manufacture the spray cans according to the invention in large numbers.
- the upper can section with the shoulder area and with the can opening with collar and the additional shaping area is formed by the device according to claim 11 or 12.
- no additional manufacturing process is used in comparison to conventional manufacturing processes, but rather is produced by the changed or modified manufacturing process of the spray cans 10 according to the invention.
- the known manufacturing process of conventional spray cans (from the prior art) is used as far as possible in order to influence the optimized process as little as possible.
- the spray cans according to the invention can also be produced inexpensively.
- the manufacturing process for creating the upper can section with the shaping region advantageously represents the last manufacturing process in the manufacturing process of unfilled spray cans.

- 4.1 shows a longitudinal section through a die, shown in front view, of a device for creating the upper can section with the shaping area of the spray can in a first production section; 4.2 longitudinal section through the die shown in side view from FIG. 4.1;
- FIG. 5.1 shows a comparable longitudinal section to FIG. 4.1 through a further die for a second production step, see also section V. 1 - V. 1 from FIG. 5.3;
- FIG. 5.2 shows a comparable longitudinal section to FIG. 4.2 through the die from FIG. 5.1, see also section V.2-V.2 from FIG. 5.3;
- FIG. 5.3 cross section V.3 - V.3 through the die from Fig. 5.1;
- Fig. 6.1 top view of a rotatable clamping plate as part of a device for manufacturing the upper can section with shaping area;
- FIG. 6.2 Side view of the device with the clamping plate and the punch plate with the matrices arranged.
- the spray can 10 is made of metal and has a lower and an upper can section 11, 13.
- the lower can section 11 contains a bottom 12 and an almost cylindrical can wall, so that the cross sections of the spray can 10 in the area of the lower can section 11 are circular. All cross sections in the area of the lower can section 11 are circular with the same area.
- the upper can section 13 has a shoulder area 14 and a can opening 15 with a collar 16 for a spray system that can be used.
- Previously known spray cans are also cylindrical in the upper can section 13, so that their cross sections in this area are also circular.
- the shoulder region 14 represents a transition region in which the larger cross-sectional area of the cylindrical can body tapers continuously to the smaller cross-sectional area of the can opening.
- various shoulder areas 14 are known which have a round shoulder, angled shoulder or a grooved shoulder.
- a cross section in the known shoulder areas 14 is always circular.
- Cross sections in the shaping area 17 of the spray can 10 are configured differently from the almost circular cross sections of the lower can section 11.
- FIGS. 1 to 3 show a spray can 10 which has oval cross sections in the shaping region 17 of the spray can 10.
- the V-shaped design of the spray can 10 can be seen in FIG. 1.
- the spray can 10 sliding away is significantly reduced when it is used, in particular when the spray system is operated with slippery fingers.
- the lower can section 11 has a constant circular cross section. In this area of the lower can section 11, the spray can 10 is encompassed by a clamping device 23 in a manufacturing process described in more detail below.
- the spray can 10 advantageously has a substantially constant wall thickness over the circumference of the cross section and over the height (longitudinal extent) of the spray can wall. This means that the wall thickness of the spray can 10 is essentially constant in the radial and axial dimensions. This ensures a high level of safety for the spray can 10, in particular at a high filling pressure. This is of great importance because the filling pressure is affected by external circumstances, such as Temperature fluctuations, can be strongly influenced.
- the spray can 10 must also withstand special requirements, for example if it is delivered to direct sunlight in the car.
- the circumference of the circular cross-section from the lower can section 11 be of the same size as the circumference of the different cross-section in the shaping region 17.
- This described measure has a direct influence on the desired constant wall thickness of the spray can 10.
- the surface of the different cross-sections in the shaping area 17 is oval or elliptical.
- This shape of the spray can 10 ensures ergonomic handling, while at the same time achieving maximum safety. It is advisable to do without particularly narrow radii in the circumference of the cross section in the shaping region 17.
- the area of the different cross-section in the shaping region 17 can also have any other shape and thus approach a triangle or rectangle, the corners also being realized here by the largest possible radii. Due to the freely selectable shape of the spray can 10, any other ergonomic handling of the can can be achieved with a simultaneous, pleasant appearance.
- the spray can 10 Since, as already mentioned, spray cans are now a mass product, it is expedient for the spray can 10 to have a standardized can opening 15 into which standardized spray systems can be used.
- the can opening 15 is generally circular. This is also the Collar 16 affected because it is also important for the standard spray systems.
- the spray can 10 with an applied spray system is advantageously suitable for a filling pressure between 5 and 35 bar, but in particular for a filling pressure between 10 and 20 bar or for a filling pressure between 12 and 18 bar.
- the filling pressure can be significantly above the values mentioned when the spray can 10 is exposed to strong heating.
- the metal of the spray can 10 consists of tinplate or aluminum.
- all alloys in the area of tinplate or aluminum are also included here.
- the device 20 contains one or more dies 24 for producing the upper can portion 13 with the shoulder region 14 and with the can opening 15 with the collar 16 from a cylindrical hollow body 25 with a bottom 12, the shape of the upper can section 13 being determined by the contours 30 of the die 24.
- This device 20 is used to press the spray can 10 out of a cylindrical hollow body 25a with a bottom 12.
- the contours 30 of the die 24 are designed in such a way that the different shaping area 17 of the spray can 10 can also be formed by using different cross sections in the shaping area 17 of a die 24 the circumferences 31 of the contours 30 are not circular.
- the device 20 thus also directly produces the different shaping region 17 in the upper can section 13.
- this manufacturing process consists of individual manufacturing steps, as indicated in FIGS. 6.1 and 6.2.
- a cylindrical hollow body 25a with a base 12 is attached to a clamping device 23 on the rotatable clamping plate 21 of the device 20.
- the Slidable stamp plate 22 with the dies 24 attached to it to the clamping plate 21 (see arrow 27).
- the shape of the cylindrical hollow body 25a is converted to the shape of the cylindrical hollow body 25b.
- the clamping plate 21 rotates in the direction of rotation 26 by a certain angle.
- the device 20 consequently also contains the rotatable clamping plate 21 with the clamping devices 23 and the displaceable stamping plate 22 with the receptacles for the dies 24.
- the contours 30 advantageously have circumferences 31b of the same length in the case of different cross sections in the shaping region 17 of a die 24. This achieves the special shape in the shaping area 17 of the spray can 10.
- FIGS. 4.1 and 4.2 show a first die 24a, which is attached to the device 20, in particular a displaceable stamping plate 22 is.
- This die 24a is shown in FIG. 1 as a longitudinal section through a front view, whereby the contour 30a is clearly visible.
- This die 24a is used for the first forming step of the cylindrical hollow body 25a.
- the contour 30a has an oval cross section in the opening which is open at the bottom (see different diameters in the shaping region 17). This cross section tapers towards the top and becomes circular for the can opening 15. 5.1 to 5.3 a second die is shown, which is used for the second manufacturing step of the cylindrical hollow body 25b.
- FIGS. 4.1 and 4.2 show a first die 24a, which is attached to the device 20, in particular a displaceable stamping plate 22 is.
- This die 24a is shown in FIG. 1 as a longitudinal section through a front view, whereby the contour 30a is clearly visible.
- This die 24a is used for the first forming step of the cylindrical
- the collar 16 is partially molded onto the can opening 15 by this die 24b.
- the circumference 31b of the contour 30b can be clearly seen in the cross section V.3 - V.3 from FIG. 5.3. This circumference 31b of the contour 30b is oval.
- the matrices 24a, 24b shown are only exemplary configurations and are therefore not necessarily used in the form shown in the manufacturing process for spray cans 10. However, they should represent the principle of the individual forming steps in the manufacturing process e).
- the invention is also directed to a method for manufacturing the spray can 10, in which at least the following manufacturing processes, which themselves consist of several manufacturing steps, are present:
- the device 20 according to claim 11 or 12 is used, as a result of which the different shaping area 17 of the upper can section 13 can also be formed. Consequently, this modified manufacturing method of spray can 10 is similar to the known manufacturing method of aerosols from the prior art. Only the manufacturing process e) differs in the use of the device 20 according to the invention. This does not change the optimized manufacturing process for the spray cans known from the prior art. Consequently, there are also no additional costs for the production of the spray can 10 with the shaping region 17.
- the manufacturing process a) for manufacturing an almost cylindrical hollow body 25a with the bottom 12 is achieved by an inexpensive deep-drawing method.
- the previously mentioned backward hollow pressing method should be considered here.
- the molding of the upper can section 13 with the shaping area 17 can also be achieved by a simple pressing process.
- the manufacturing process e) for creating the upper can section 13 with the shaping region 17 represents the last manufacturing process in the manufacturing process of unfilled spray cans 10. After this manufacturing process e), the spray cans created c) are bundled by a large tensioning belt and made available in stacks for transport to a filling company.
- the spray cans 10 it is advisable to design the spray cans 10 in such a way that the shape of the spray cans 10 balances each other when bundling, ie the spray cans are close together, since otherwise the bundle becomes thicker upwards or downwards and thus the hold by the tensioning strap would lose.
- the embodiment of the spray can 10 and the device 20 shown here are only exemplary implementations of the invention. However, this is not limited to this. It is understood that the illustrated forms and parts of the invention can also be present in other designs and constructions which have similar properties to those described here. There is also no distinction between a spray can and a spray can.
- Spray can lower can section, bottom, upper can section, shoulder area, can opening, collar, shaping area, device, rotatable clamping plate, displaceable stamping plate, clamping device, a die for the first manufacturing step, b die for the second manufacturing step, c die for the third manufacturing step, a cylindrical hollow body before the first manufacturing step, and cylindrical hollow body before 2.
