SUMMARY OF THE INVENTION
It is an object of the invention to come up with a sunscreen dosing device which is easy to use, inexpensive and simple of construction.
An embodiment of the sunscreen dosing device comprises a cup with a structured elongation. The cup is defined by an upper rim, a bottom and a side wall, connection the upper rim and the bottom. The structured elongation is an integral part of the cup. Furthermore, a first ear with a through hole is an integral part of the cup. A second ear with a through hole is an integral part of the cup and formed oppositely to the first ear of the structured elongation. The second ear is an integral part of the structured elongation. A free end of the structured elongation is insertable in the through hole of the first ear or the second ear.
The advantage of the sunscreen dosing device is that it is of one piece construction and can be produced in a simple and inexpensive way. Additionally, the sunscreen dosing device is easy to handle and to store.
In addition to manually fixing or attaching the sunscreen dosing device to a body part of other devices, a free end of the structured elongation is insertable in the through hole of the first ear or the second ear.
In order to allow a fixation or attachment of the sunscreen dosing device to the body part of another device, the structured elongation has a plurality of sub-structures which are arranged periodically along a longitudinal axis of the structured elongation. Each sub-structure has a maximal width and a minimal width, wherein the maximal width is larger than a width of the though holes formed in the first ear or second ear.
The sunscreen dosing device is made from a thermoplastic elastomer or an elastomer and the sunscreen dosing device is of a one piece construction. The sunscreen dosing can be made by an injection molding process. The flexibility of the material of the sunscreen dosing device allows easy attachment other parts and avoids damage or breakage of the sunscreen dosing device.
According to a further embodiment, the sunscreen dosing device is formed with at least one radial reduction in thickness in the sidewall of the cup. The reduction in thickness and the reversible flexibility of the material of the sunscreen dosing device enable a collapsibility of the cup (reduction in height).
According to one embodiment, at least one mark for a defined amount of sunscreen is provided close to the upper rim at an inner surface of the sidewall of the cup. The advantage of the mark is a calibrated sunscreen dosing or measuring device.
It is a further object of the invention to come up with a sunscreen bottle which holds a device for measuring a defined amount of sunscreen which should be applied to a human body.
According to one possible embodiment of the invention, a sunscreen dosing device is attached by form and force fit to a body of a sunscreen bottle.
The advantage is that a measuring device for the correct amount of sunscreen is always available and ready to use.
In order to mount or attach the sunscreen dosing device to the sunscreen bottle, the sunscreen dosing device has a structured elongation. The structured elongation is flexible and can be wrapped around the body of the sunscreen bottle. For mounting purposes a free end of the structured elongation of the sunscreen dosing device is inserted into a through hole of a first ear or a second ear of a cup of the sunscreen dosing device.
In order to support or fix the sunscreen dosing device to the sunscreen bottle a plurality of sub-structures of the structured elongation are arranged periodically along a longitudinal axis of the structured elongation. Once the sunscreen dosing device is in form and force fit with the body of the sunscreen bottle one sub-structures, which has a maximal width larger than a width of the though holes of the first ear or the second ear, cooperates with the hole of the first ear or the second ear. This cooperation allows a secure fixation of the sunscreen dosing device to the body or body part of the sunscreen bottle.
The sunscreen dosing is made from a thermoplastic elastomer or an elastomer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to various embodiments, examples of which are illustrated in the accompanying drawings. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the various described embodiments. However, it will be apparent to one of ordinary skill in the art that the various described embodiments may be practiced without these specific details. In other instances, well-known methods, procedure and components, have not been described in detail so as not to unnecessarily obscure aspects of the embodiments.
FIG. 1 shows a perspective view of the sunscreen dosing device 1. The sunscreen dosing device 1 comprises a cup 2 for receiving the sunscreen and a structured elongation 3 which is integrally formed with the cup 2. The structured elongation 3 has a length L3 and a free end 6. Preferably, the sunscreen dosing device 1 is fabricated by an injection molding process from a material which exhibit a certain flexibility. The material of the dosing device 1 could be a thermoplastic elastomer or an elastomer. Thermoplastic elastomers (TPE), sometimes referred to as thermoplastic rubbers, are a class of copolymers or a physical mix of polymers (usually a plastic and a rubber) that consist of materials with both thermoplastic and elastomeric properties. While most elastomers are thermosets, thermoplastics are in contrast relatively easy to use in manufacturing, for example, by injection molding. Thermoplastic elastomers show advantages typical of both rubbery materials and plastic materials. The benefit of using thermoplastic elastomers is the ability to stretch to moderate elongations and return to its near original shape creating a longer life and better physical range than other materials. The principal difference between thermoset elastomers and thermoplastic elastomers is the type of a cross-linking bond in their structures. In fact, cross-linking is a critical structural factor which imparts high elastic properties.
FIG. 2 shows a top view of the sunscreen dosing device 1. The cup 2 of the sunscreen dosing device 1 is open at an upper rim 9 and closed at the opposite end by a bottom 10. A surrounding sidewall 11 (see FIG. 3) connects the upper rim 9 and the bottom 10. A first ear 4 and a second ear 5 formed oppositely to the first ear 4 are integral parts of the cup 2. In addition, the second ear 5 is an integral part of the structured elongation 3 and arranged opposite to the free end 6 of the structured elongation 3. Both the first ear 4 and the second ear 5 have a through hole 7 having a width W7. The structured elongation 3 has a plurality of sub-structures 8, which are arranged periodically along the longitudinal axis A of the structured elongation 3. Each sub-structure 8 has a length L8 which is smaller than the length L3 of the structured elongation 3. Each sub-structure 8 has a maximal width W3Max and a minimal width W3Min. The maximal width W3Max is larger than the width W7 of the through holes 7. With the free end 6 the structured elongation 3 can be inserted into the through hole 7 of the first ear 4 or the second ear 5. The mechanical cooperation of the portion of one of the sub-structures 8 having the maximal width W3Max with the through hole 7 of the first ear 4 or the second ear 5 enables the fixation of the sunscreen dosing device 1, for example, to a sunscreen bottle 32 (see FIG. 13).
FIG. 3 shows a side view of the sunscreen dosing device 1. The first ear 4 and the second ear 5 with the structured elongation 3 and its sub-structures 8 are flush with an upper rim 9 of the cup 2. Opposite to the upper rim 9 the cup 2 is closed by a bottom 10. The sidewall 11 is designed such that the cup 2 has a conical shape.
FIG. 4 shows a side view of a cup 2 of the sunscreen dosing device 1. The present view is on the outer surface 12O of the sidewall 11 of the cup 2 at which the first ear 4 is formed. The cup 2 has an outer diameter DO2 of the upper rim 9 and an overall height H2. The cup 2 has a structured sidewall 11. In the embodiment shown here the structured outer surface 12O of the sidewall 11 defines three distinct sections 22. The number of sections 22 should not be regarded as a limiting factor of the invention. It is clear for anybody skilled in the art that the number of sections 22 vary due to the design of the cup 2.
FIG. 5 shows a cross-sectional view of the cup 2 of the sunscreen dosing device 1 as shown in FIG. 4. The cup 2 has an inner diameter D9 at the upper rim 9. From the upper rim 9 to the bottom 10 the inner diameters are decreasing. In the embodiment shown here, an inner diameter D122 of the first section 22, following the upper rim 9, is smaller than the inner diameter D9 at the upper rim 9. An inner diameter D222 of the second section 22, following the upper rim 9, is smaller than the inner diameter D122 of the first section 22. An inner diameter D322 of the third section 22, following the upper rim 9, is smaller than the inner diameter D222 of the second section 22. An inner surface 12I of sidewall 11 of the cup 2 has a rounded shape 13 at the transition from the inner surface 12I of sidewall 11 to the bottom 10. The rounded shape 13 has the advantage that one can easily get all the sunscreen out of the cup 1. The bottom 10 of the cup 2 has a defined thickness T10.
FIG. 6 shows the construction of the sidewall 11 of the cup 2 of the sunscreen dosing device 1. The sidewall 11 which stretches from the upper rim 9 to the bottom 10 has at least one radial reduction 14 in the sidewall 11 of thickness T11. The reduction 14 supports the collapsibility of the cup 2. The at least one reduction 14 is correlated with the distinct sections 22 (see FIG. 4) of the cup 2. In the possible embodiment shown here, the cup 2 has two radial reductions 14 in the sidewall 11.
FIG. 7 shows an enlarged view of a portion of inner surface 12I of the sidewall 11 of the cup 2. At least one mark 15 is provided close to the upper rim 9 the inner surface 12I of the sidewall 11. The at least one mark 15 is stamped at the inner surface 12I of the sidewall 11. The volume unit 18, written on the inner surface 12I of the sidewall 11 should not be regarded as a limitation of the invention.
FIG. 8 shows a perspective view of one possible embodiment for using the structured elongation 3 of the sunscreen dosing device 1. The free end 6 of the structured elongation 3 is inserted from the bottom up 25 into the through hole 7 of the first ear 4 of the cup 2.
FIG. 9 shows a perspective view of one further embodiment for using the structured elongation 3 of the sunscreen dosing device 1. The free end 6 of the structured elongation 3 is inserted from above 26 into the through hole 7 of the first ear 4 of the cup 2.
FIG. 10 shows a perspective view of the embodiment shown in FIG. 9, wherein the structured elongation 3 is pulled tight. The structured elongation 3 is pulled with the free end 6 through the through hole 7 of the first ear 4. The structured elongation 3 comes close to the upper rim 9 of the cup 2, so that the sunscreen dosing device 1 can be removably fixed to an article (not shown). As shown in FIG. 2 the maximal width W3Max of a sub-structure 8 is cooperates with the smaller width W7 of the though holes 7. This cooperation holds the structured elongation 3 in place at the first ear 4.
FIG. 11 shows a perspective view of a further embodiment, wherein the structured elongation 3 is pulled tight. The structured elongation 3 is pulled with the free end 6 through the through hole 7 of the second ear 5. The structured elongation 3 comes close to the second ear 5 of the cup 2, so that the sunscreen dosing device 1 can be removably fixed to an article (not shown). As shown in FIG. 2, the maximal width W3Max of a sub-structure 8 cooperates with the smaller width W7 of the though holes 7. This cooperation holds the structured elongation 3 in place at the second ear 5.
FIG. 12 shows a perspective view of a further possible embodiment to use the structured elongation 3 of the sunscreen dosing device 1. Here the cup 2 of the sunscreen dosing device is collapsed (the height H2 of the cup 2 is reduced as compared to the height H2 of the cup 2 in the not collapsed state (see FIG. 4)). The free end 6 of the structured elongation 3 is inserted from above 26 into the through hole 7 of the first ear 4 of the cup 2.
FIG. 13 shows a perspective view of the sunscreen dosing device 1 fixed to a body 30 of a sunscreen bottle 32. Here the body 30 of the sunscreen bottle 32 is implied by a plurality of broken lines. The sunscreen dosing device 1 is attached to the body 30 of the sunscreen bottle 32 in that the collapsed cup 2 and the structured elongation 3 are in contact with the body 30 of the sunscreen bottle 32. It is noted here that the sunscreen dosing device 1 can be attached to the body 30 of the sunscreen bottle 32 as well with the cup 2 which is not collapsed. It is to be noted that the sunscreen dosing device 1 can be attached as well to the neck (not shown) of a sunscreen bottle 32. The expression body encompasses all parts of the sunscreen bottle 32.
