Abstract

The invention concerns a plastic part with an indication, lettering or marking, the plastic being at least semitransparent to light. According to the invention, a contour in the form of an indication, lettering or marking is provided on the rear side opposite the visible side.

Description

description

Plastic part with a display, inscription or marking

[0001] The invention relates to a plastic part with a display, inscription or marking according to the preamble of claim. 1

[0002] ads, labels or marks are usually complicated by various printing methods such. B. pad printing or screen printing, applied to plastic parts. These known printing methods require an additional operation in the production of the plastic part and thus affect considerably on production costs from. Other known methods for applying markings, such as hot embossing process, require an additional process step, thereby increasing the production costs.

[0003] It has therefore already been proposed to label the display or label as a raised or recessed contour on the visible surface of the plastic part z. B. be attached to a vacuum cleaner housing or the like. In particular for injection molded parts, this contour has already been incorporated into the tool, so that no additional work step is required here to the injection-molding. The production costs could be considerably reduced.

[0004] It has been found, however also disadvantages of this method over the prior art printing of displays, labels or markings on plastic parts. So it is for instance not be excluded that by the placement of markings and / or inscriptions on a user z. As a vacuum cleaner readily accessible and, if used in the use of the vacuum cleaner or managed support side, these labels and markings can be disturbing. In addition, it is possible that wear these labels and uses in the use of the plastic part and therefore no longer serve their purpose. In particular, raised, square or sharp-edged contours have this disadvantage. In-depth contours, it has been found that these increasing z. As synonymous with dirt and thus are becoming less visible.

[0005] It was therefore the object of the invention to provide a plastic part with a display, printing or marking, wherein no additional step is necessary for the application, the display label or marker. Even the plastic part should pose no additional risk of injury in itself. The visibility, marking the display or marking should not be impaired even after prolonged use.

[0006] The object is achieved by a plastic part having the features of claim 1. By attaching the contour on the opposite side of the rear view of the plastic part, the visible side remains smooth. The visible surface of the plastic part can therefore make good and can be maintained also awarded during use. Since the visible side remains unchanged, even the appearance of the plastic part is not adversely affected. At the same time, however, a good readability, labeling the display or marking is guaranteed. Since a user can not come up with the outline on the back of the plastic part in contact any risk of injury is excluded.

[0007] The contour may be formed recessed from the back surface of the plastic part. The contour is thereby recognize the visible side of the plastic part by an observer as bright contrasting, display label or marker.

[0008] However, it is also possible to perform the contour on the back of the plastic part sublime. Such a contour is to be seen by a viewer on the visible side of the plastic part as a dark display, inscription or marking. When using a stained plastic, the contour appear on the visible side in a more intense color than the surrounding regions.

[0009] Both in the raised and in the recessed contour can be influenced by the height of the contour visibility. The greater the difference between the contour and the surrounding surface of the back is, the better the contour of the visible side of reveals.

[0010] The invention is explained in more detail below with reference to the drawing. It shows:. FIG. 1 is a cross section through an inventive plastic part with recessed contour, Figure 2 is a cross section through an inventive plastic part with a raised contour and Figure 3 is a plastic ring with markings for a Saugkraftanzeige..

[0011] In Fig. 1 a plastic part 1 having a double mark 3 is shown. The plastic part 1 is made of a transparent plastic stained. The plastics part 1 has a visible side 2 and a side view of the opposite rear side 5 on. The mark 3 is formed by a contour 4 which is recessed from the surface of the backside. 5 Since the plastics material is thinner than in the remaining area above the recess 4, the marking 3 has an effect to an observer, from the visible side 2, brighter than the surrounding regions. The coloring of the plastic affects less intense at this point.

[0012] In Fig. 2 shows the same plastic part 1 is shown with a raised contour 6 as the mark 3. Here, the effect is the reverse of the plastic part according to Fig. 1. The mark 3 acts as seen from the visible side, a viewer darker and more intense color than the surrounding regions.

[0013] Since the contour 4 and 6 respectively located on the back of the plastic part, the surface remains smooth on the visible side 2 and can therefore be easily maintained. It is neither clogging of the depression caused by dirt particles nor the risk of injury to the raised contour to fear. Both the contour 4 and the contour 6 can already be provided during the injection molding of the plastic part. 1 Advantageously, the injection mold is provided at the Auswerfseite with a corresponding contour, ie for the plastic part of Fig. 1 with a raised contour and for the plastic part of Fig. 2 with a recessed contour.

[0014] Fig. 3 shows an application example of the invention to a vacuum cleaner. With newer models, an electronic suction power is often provided. To this end, markings are necessary to reflect the current setting. Fig. 3 shows a plastic ring 7 which is provided with appropriate markings 3. In the circular opening 8, the knob not shown here, with which the setting is carried out usually is. The ring 7 can be inserted flush into the housing of the vacuum cleaner, so that a completely smooth surface. The ring is made of-stained, lichtteildurchlässigem plastic. The marks 3, as shown in the plastic part according to Fig. 1 or the plastic part according to Fig. 2, may be formed. However, the plastic part can also be manufactured in one piece with the housing of the vacuum cleaner, so that the display for the suction power control in a single operation can be prepared together with the vacuum cleaner housing.

[0015] As mentioned above and in the display for the suction power, the markings clearly visible, can not be unreadable and can not cause any injury to a user through pollution. As an added bonus there is a good customizable, smooth and easy to clean surface.
