DE102008010085A1 - Dosing cap for closing container i.e. bottle, of package, has dead plate dividing cylinder element into two sections, where outer surface of one of sections comprises roundness depth of specific micrometer - Google Patents

Abstract

The cap (1) has a cup-like cylinder element (2) provided with a base (3) and a lateral surface (4). A circulating dead plate (5) is arranged at the lateral surface of the cylinder element and comprises a fastening unit that causes a liquid-tight, removable closing of the container with another fastening unit arranged at the container. The dead plate divides the cylinder element into a section (7) and another section, where an outer surface of the former section has a roundness depth of 0.25 to 1.5 micrometer, while the remaining surface has another roundness depth of 0.1 to 0.15 micrometer. Independent claims are also included for the following: (1) a method for producing a dosing cap (2) a method for automatic screwing of a dosing cap.

Description

The The invention relates to a molded plastic dosing for Closing one with pourable or pourable Washing or cleaning agent filled container and for measuring and dosing flowable or pourable Washing or cleaning agents from the container, the Dosing cap according to the invention optimized grip properties, in particular anti-slip properties. Further concerns The invention relates to a method for screwing on such a dosing on the container opening of a container, especially a bottle.

State of the art

Out Plastic molded dosing caps for closing a with pourable or pourable washing or detergent filled container as well for measuring and dosing flowable or pourable Washing or cleaning agents from the container are sufficient known from the prior art.

Usually Such closure caps have a cylindrical Base on, closed by a bottom, cup-like is trained. On this cylindrical body is regularly arranged an apron on which is usually a thread with which the cap screwed liquid-tight with the opening of the container can be.

One Problem with the handling of such cap is that the plastic surfaces of the cap comparatively are smooth, so they are, especially with moist or greasy Hands, often quite laboriously open leaves, especially when in the threads of the screw cap Thickened or trashed detergent or cleaning agent deposited Has.

To improve the grip properties is for example off US2005 / 0145593 a dosing with inserts of a thermoplastic elastomer (TPE) known. Due to the rubber-like TPE strips, the grip of the dosing cap can be improved in particular when unscrewing and screwing onto a corresponding bottle. However, the introduction of TPE strips into a dosing cap is technically complex and thus expensive.

Further are used to optimize the grip properties of dosing caps At the beginning, they are often referred to as anti-slip coatings applied to the surfaces in the grip area of the dosing caps. This coating must be in an additional manufacturing step be applied to the dosing. This is correspondingly expensive and therefore not desirable.

Object of the invention

task The invention therefore is a dosing of the above To provide a kind that can be produced at low cost A way to improve the grip properties as well as a secure Screwing in automatic filling systems ensured.

These Task is accomplished by a dosing with the characteristics of Claim 1 and by a method having the features of the claim 14 solved.

By introducing a first roughness depth of Ra 0.25 to 1.5 μm into the outer surface of the outward-facing portion, while the remaining surface has at least a second roughness depth of Ra 0.1 to 0.15 μm,
These surface roughnesses of the dosing cap can be produced by appropriate treatment of the shaping tool, for example by a suitable etching of the tool.

In An advantageous embodiment of the invention, the sections same first roughness depth radially on the outer Surface of the outward-facing section arranged. As a result, rotational movements of the dosing, in particular when mounting or screwing the dosing through automatic handling devices easier to detect and thus the exact positioning of the dosing improved relative to the container to be closed. Especially with transparent and smooth surfaces consists in the automatic handling of such Dosierkappen the problem that the rotational movement of the dosing when screwing on the container is difficult to optically detect. The corresponding procedure is described in more detail in the description section explained.

1 shows an embodiment of the metering cap according to the invention with radial portions of first roughness in a perspective view. The sections of first roughness 7 extend strip-shaped, radial over the ground 3 the dosing cap 1 , the cylinder element 2 as well as the apron 5 , The individual sections 7 are each spaced apart.

The outward facing section 7 has a first roughness of Ra 0.25 to 1.5 microns, while the remaining surface 4 has at least a second roughness depth of Ra 0.1 to 0.15 microns.

2 shows the off 1 known design of the dosing with radial sections first roughness in a side view.

Another alternative embodiment of the invention is shown in FIG 3 displayed. 3 shows one with product 12 filled dosing cap 1 with concentric sections of first roughness 2 , The concentric sections of first roughness are spaced apart from each other and may, inter alia, serve as Befüllmarkierung for the product to be dosed. Between the spaced-apart concentric portions of first roughness 2 are the sections of second roughness 4 arranged.

The 3 shows that the sections first roughness 7 only over the cylinder element 2 the dosing cap 1 run. However, it is also possible that the sections first roughness 7 also over the apron 5 are formed. This can be particularly beneficial if the apron 5 also as handle element for screwing on or off the dosing cap 1 should be used, leaving the surface of the apron 5 provides an anti-slip effect and thus better manageability for the user.

The first roughness section may also be circular or oval on the surface of the cylinder element 2 be positioned in what 4 is reproduced. On the opposite side of the in 4 recognizable section of first roughness 7 , lies a substantially identical section of first roughness, resulting from the 4 is not apparent. Due to the opposite arrangement, the dosing 1 For example, it can be ergonomically held and used with the thumb and forefinger of one hand.

It is also possible, by the arrangement of the sections first and second roughness 4 . 7 an information element 13 form, which is for example a text and / or a picture element. In 5 this is shown by way of example.

Method for screwing on the dosing cap

The method for automatically screwing the cap according to the invention on the container opening of a container, in particular a bottle, is described below with reference to 6 explained in more detail.

6 shows a light source 9 that a ray of light 10 emitted by the rotation axis of the rotationally symmetrical, at least partially transparent dosing 1 runs. Advantageously, the light source 9 a laser. The light beam 10 preferably has a width which is less than or equal to the distance between two adjacent sections of the same first roughness depth.

The dosing cap 1 , in the 6 is shown in the plan, each has two opposing, radially extending portions first roughness 7 on. In a first rotational position around the axis of rotation of the dosing cap 1 in the upper part of the 6 is shown, the opposing sections 7 first roughness depth of the light beam 10 is irradiated, with this each weakens, which is indicated in the figure by the decreasing line thickness, and on exit from the Dosierkappe 1 has a first intensity.

In the lower part of the 6 The configuration shown is the dosing cap 1 in a second rotational position about the axis of rotation in the opposite sections 7 not from the light beam 10 be irradiated so that it exits the dosing 1 has a second intensity which is greater than the first one. Again this is indicated by the corresponding line thickness 6 indicated.

The light beam 10 meets after exiting the dosing cap 1 on a detector 11 , which is suitable for the intensity of the light beam 10 to convert into an electrical signal.

This electrical signal can be converted into digital information for example, the signal that the first, weaker Intensity corresponds to a zero and the signal that the second, stronger intensity, is converted into a 1 (one).

When screwing on the dosing cap 1 on the container opening can be so from the number and arrangement of the sections 7 and from the sequence of electrical signals, the number of revolutions, for example by a corresponding Prozes sor, be determined.

With knowledge of the design of the thread on the dosing 1 and the container opening can thus be determined which number of revolutions of the dosing cap for a firm, liquid-tight fit of the dosing 1 on the container closure is necessary.
