Definitions

  • the purpose of the present invention is to provide an easy-to-use and, at the same time, shapely, thus aesthetically appealing casting mold for the in-house production of lipsticks. It should offer the possibility of being able to control the product, i.e. the poured lipstick, well during production, in order to be able to observe and check the quality of the later product already during the initial stages of production. Such a mold should also be easy to use and clean. It should enable easy filling and also a convenient removal of the finished lipstick. The finished product should look as neat as possible, if not professional, so it should differ as little as possible from the ready-made lipsticks on the market.
  • the mold is therefore generally suitable for consumer classes who, on the one hand, have fun making a cosmetic product, in this case a lipstick, and on the other hand appreciate the money advantage that is associated with self-production compared to commercially available products.
  • the invention has for its object to provide an easy-to-use, namely easy to fill, easy to control in the filling state until the solidified lipstick is removed, which allows easy removal of the finished lipstick and overall the manufacturing steps for the manufacture of Lipstick relieved with home improvement tools.
  • the casting mold consists of two largely identical, preferably identical mold halves, which have fitting means for mutual, exact fitting contact, which touch in the assembled state on a separating surface and, on the one hand, a largely cylindrical, lipstick-shaped, open-topped Limit the mold cavity, the axis of which lies in the separating surface and, on the other hand, limit an overlying filling area, and that both mold halves are made of a transparent material.
  • the fitting means serve to match the two mold halves clearly and precisely so that they form the casting mold.
  • the two mold halves touch on a dividing surface, thereby limiting the mold cavity for the lipstick.
  • the separating surface lies on the axis of the largely cylindrical mold cavity, whereby the separation of the two mold halves from one another and the removal of the cast lipstick are particularly simplified after the production and solidification of a lipstick.
  • a filling area is located above the entrance area of the mold cavity. It serves to simplify the filling into the rather narrow mold cavity, it essentially has the function of a funnel, so it serves to make more liquid during the casting process Material can be filled in the unit of time than can actually flow through the circular inlet area into the mold cavity. In addition, the amount to be filled in does not have to be measured exactly, it can certainly be larger than is required for the actual lipstick.
  • the superfluous material remains in the filling area and solidifies together with the material that is in the mold cavity. The material in the filling area can later be cut away, for example with a sharp knife or a razor blade. It makes it easier to remove the solidified lipstick body because it can be used as a handle.
  • due to the construction only the rear end of the lipstick becomes imprecise, while the front end, which is located in the mold below, and the entire jacket are precisely cast in the selected production.
  • the manufacture of the two mold halves from a crystal-clear material, for example acrylic by injection molding makes it possible to be able to closely monitor and control the production steps during manufacture. On the one hand, it can be followed whether the mold cavity fills without bubbles, whether enough has been filled in, and later it can be observed without opening the mold whether the filled mass has already solidified. Due to the crystal-clear design, you can also see whether the casting process went well, i.e. whether streaks have formed or not.
  • the crystal-clear design gives the overall shape a special aesthetic appeal and increases the pleasure of working with this mold.
  • the fitting means can be of any design, so it is possible, for example, that protrusions protrude from one mold half on the separating surface, which engage in correspondingly adapted recesses in the other mold half or come to rest on side surfaces.
  • the two mold halves differ, if at all, only in terms of their fitting means.
  • the fitting means can be designed so that the two mold halves are completely identical.
  • different but cooperating fitting means are provided on both sides of the axis of the mold cavity lying in the separating surface. These must be in places which are fold symmetrical to the axis.
  • the two mold halves are largely cuboid, the separating surface is square, in it the mold channel is provided in the center.
  • each mold half has a footprint that is perpendicular to the axis of the mold cavity and is in the same plane as the footprint of the other mold half. This enables the two mold halves to stand upright independently and to be joined together in this state, for example when they are on a table top. Furthermore, it is possible that the mold itself stands, that is, it does not have to be held during the filling process and does not have to be supported later in the refrigerator.
  • the aforementioned production of the mold halves by injection molding ensures that the inner surfaces of the two mold channels forming the mold cavity are extremely smooth, so that the finished product, i.e. the lipstick, has the preferred, completely smooth surface, which particularly emphasizes its components and on one professionally manufactured product.
  • the separating surfaces are preferably relatively wide at the sides and downwards, so that a larger distance of several millimeters, for example 10 mm, remains between the edge of the mold channel and the side surface or standing surface of the mold.
  • This has the following advantage: If the two mold halves do not touch exactly in the area of the mold cavity, some of the cast material flows between the two parting surfaces. However, the gaps there are narrow, the liquid starting material for the lipstick is viscous. Because of the be written greater distance cools the material faster before it can run out of the mold on the side surfaces or in particular in the area of the footprint.
  • the mold for lipsticks consists of two essentially cuboidal mold halves 10, 12, which are completely identical. They are made of crystal clear acrylic by injection molding.
  • the surface facing the viewer in FIG. 1 is a separating surface 14.
  • a molded channel 16 is incorporated, which has the shape of a half, axially cut lipstick.
  • a mold cavity 18 is formed, which has a lipstick shape, that is to say is largely cylindrical.
  • the axis 20 of this body lies in the separating surface 14. This axis also forms - with the exception of the fitting means 22, 24 to be described later - a line for mirror symmetry of the mold halves 10 and 12, respectively.
  • the fitting means 22, 24 are provided at mirror-image locations to the folding symmetry line (axis 20), but the mirror image pairs are each designed differently, that is, a negative fitting means on one side is opposite a positive fitting means arranged in a mirror image on the other side.
  • a pin 22 is arranged to the right of the axis 20 and jumps forward at right angles from the separating surface 14. It is on the left side of the axis 20 assigned a correspondingly adapted blind bore 24.
  • the pin 22 and the blind bore 24 are matched to one another in such a way that, on the one hand, a precise fit is achieved in the composition of the two mold halves 10, 12 and, on the other hand, clamping is achieved, which makes it difficult to open the mold unintentionally.
  • the fitting means can also be designed in another form. If the identity of both mold halves is dispensed with, the mold half 10 shown in FIG. 1 can only have blind holes 24, for example, while the other mold half 12 has two pins 22 as shown in FIG. 2. Deviating from the exemplary embodiment shown, more than just a pair of fitting means 22, 24 can also be provided.
  • the fitting means can be arranged on the edge, project significantly less than the pin 22 shown and can also be made smaller than this.
  • the separating surface 14 is a square with an edge length of 5 cm.
  • the cuboid has a thickness of 12 mm. It is laterally delimited by side surfaces 26. Its rear surface 28 is completely flat and unprocessed. Its lower surface is referred to as the standing surface 30, it runs at right angles to the axis 20.
  • a recess 32 is machined into an upper side 31, which together with the identical recess of the other mold half 12 forms a funnel-like filling area 34, the deepest point of which is a largely circular inlet edge 36 , from which the mold cavity 18 extends downward.
  • the volume of the filling area 34 is selected such that it essentially corresponds to the volume of the mold cavity 18.
  • the mold cavity itself has a diameter of approximately 12 mm and a total depth of approximately 40 mm in its upper, largely cylindrical region.
  • the downward-pointing region of the mold cavity 18, in which the tip of the lipstick is later formed is shaped like an ellipsoid.
  • a different shape for example a slight bevel or the like - depending on the desired shape of the tip of the lipstick - can also be provided here.
  • each mold half 10, 12 has a small bevel 38, starting from the standing surface 30, which offers a separation aid with the corresponding bevel 38 of the other mold half 12. Since the bevel runs at an angle to the parting surface, a part of the two mold halves can be separated by driving an object into the closed form, in which a solidified lipstick is located. The advantage is that the separation begins in the area of the tip of the poured lipstick, so that the demolding is best there.
  • det has about 6 mm in diameter and projects about 7 mm freely.
  • the blind bore 24 is designed accordingly, but approximately 1 to 2 mm deeper.
  • Fig. 3 shows a view from above of the closed form.
  • the filling area 34 which is essentially trough-shaped, can be seen.
  • the mold cavity 18, which appears largely circular in this illustration, is located in the center and downwards. From FIG. 3 it can be seen how the material can reach and fill the mold cavity 18 below when pouring material into the filling region 34.
  • the filling area 34 serves as a depot at the end of the filling process, it holds back excess material without the risk that it can overflow laterally.
  • the front end of the pin 22 can be made slightly spherical so that it snaps into the blind bore 24 when it is inserted.
  • Other closing means for example magnets, are also possible.
