The subject of the utility model is a cap with cup for bottles. The cup is attached to the cap with a bayonet catch. The cap is attached to the bottle with flange joint.

There are already numerous varieties for cups that can be attached to bottles. The document with Publication Number GB2161134 describes a cup in which a nut-threaded cylinder is attached to the bottom of the cup, towards the inside. It can be screwed onto the bottle. The volume of the cup is significantly higher than that of caps which can be screwed onto bottles. The cup and the cap form a unit and they are undetachable; in this way, it is not as hygienic as if it would be if the cap would be detachable from the cup.

The document with Publication Number US4150761 is the closest solution to the utility model. This document describes a cup-cap assembly, in which the cap is detachable from the cup. The attachment of the cup and the cap is ensured by axial fins inside the cup and in the cap. If the cup fins are slid into the cap fins, a strong closing joint is implemented. The cap can be pulled out from the bottom of the cup in axial direction. The disadvantage of this solution is that the cup is hard to clean because of the fins.

With the utility model, our goal is to eliminate the disadvantages of the above described solutions, as well as their ergonomic enhancement.

- The disadvantage of the cup-cap connection described in the document with Publication Number US4150761 is that the fins of the cup and the cap are difficult to clean. To solve this problem, we propose a bayonet catch between the cup and the cap which is easier to clean, and the cap can be screwed onto and from the bottle just as well by its usage.

- We also want the remaining small amount of liquid not to drop out of the cup after usage (emptying), when the cup is turned upside down and it is attached to the cap screwed onto the bottle. We solve this problem by implementing tangential, or in case of a standing bottle, horizontal knurling on the inside surface of the cup wall, in a stripe downwards from the cup mouth as well as the corresponding stripe on the external surface of the bottle.

- It is ergonomically justifiable that the cup and the bottle can be easily held in hand. To obtain that goal, surfaces that provide good adhesion must be implemented on the external surfaces of the cup and the bottle. For this purpose, we implement knurling on the bottom of the bottle, under the drop- retardant knurling as well as on the lower third of the cup. This knurling is preferably checkered or straight.

- One of our further goals is to make the cup suitable for measuring the poured liquid, so the inside surface of the cup wall is supplied with liquid level measuring stripe.

Therefore, the utility model is a cup with cap for bottles which consists of a cap and a cup with significantly higher volume than the cap. The cap has a nut- threaded cylinder part which can be screwed onto the bottle, and a bottom part which closes the cylinder. The cup has a mouth, a bottom, a wall attaching the mouth to the bottom and a cylinder-shaped cap receiving part. The cylinder shaped cap receiving part is a cylinder which is attached to the bottom of the cup, towards the inside of the cup. Its internal diameter is bigger than the external diameter of the cap; and its external diameter is smaller than the diameter of the bottom of the cup. When assembled, the edge of the cylinder part of the cap and the cup mouth face the same direction. On the inside surface of the cup wall, there is a liquid level measuring stripe. The cap is connected to the cup with a bayonet catch in such a way that on the external surface of the cylinder part of the cap, there are two T-shaped grooves, which have a tangential groove section and an axial groove section. One of the ends of the axial groove section is opened towards the end of the bottom of the cap, the other end connects to the middle part of the tangential groove section. Two pins stick out in radial direction from the inside wall of the cap receiving part; these pins fit into the T-shaped grooves implemented on the cylinder part of the cap. The inside of the cup wall touches the bottle at the cup mouth. The cup and the bottle are supplied with drop-retardant knurling as well as knurling that ensures adhesion.

The cup is connected to the cap in the following method: place the cap, with its bottom facing the bottom of the cup, into the cap receiving part of the cup in such a way that the pins reach the tangential groove sections through the axial groove sections of the T-shaped grooves. After that, turn the cap left or right, so the pins leave the axial groove section until they clash with the end of the tangential groove section.

In an advantageous embodiment of the cup with cap for bottles according to the utility model, the drop-retardant knurling of the cup and the bottle is tangential direction knurling. The drop-retardant knurling can be found on the inside of the cup and the outer surface of the bottle, in corresponding stripes. The drop-retardant knurling of the cup can be found under the cup mouth. The drop- retardant knurling of the bottle can be found on the bottle which is encircled by the drop-retardant knurling of the cup when the cup is attached to the cap and the cap is attached to the bottle.

The above described embodiment of the utility model can be characterized in case of further advantageous implementation with the fact that the knurlings ensuring adhesion can be found on three places: on the lower third of the cup, on the bottom of the bottle as well as on the bottle, from the drop-retardant knurling towards the bottom of the bottle, in one single stripe. The knurlings providing adhesion are found on the external surfaces of the cup and bottle, and advantageously consist of knurls with axially parallel grooves or knurls of crisscross pattern.

Hereinafter, an implementation example of the utility model is presented by drawings, where

• Figure 1 shows the cross section of the assembled bottle, cap and cup

• Figure 2 shows the cap in front view

• Figure 3 is the cross-section view of the cap along line A-A as indicated on Figure 2

• Figure 4 shows the half-section of the cup from side view

• Figure 5 shows the bottle in front view

Figure 1 shows the cross-section of the assembled 15 bottle, cap and cup. The 3 cup mouth touches the side of the 15 bottle. The 14 pins, protruding to the inside of the cup from the 6 cap receiving part, are opposite to each other and they are sectioned in the middle in this cross-section. The 14 pins, as seen on Figure 1, are at the connection of the axial groove section and the 9 tangential groove section. From this position, the cup can be turned so that the ends of the 9 tangential groove sections clash with the 14 pins where they can exert a torque on the 1 cylinder part of the cap. In the state which is depicted on Figure 1 , the cap is screwed onto the 15 bottle.

Figure 2 shows the cap in front view and it can be seen that the 7 T-shaped groove consists of an 8 axial groove section, which is opened at the 2 bottom of the cap and rounded on both ends; as well as a 9 tangential groove section connecting to the 8 axial groove section.

Figure 3 shows the cross-section view of the cap along line A-A as indicated on Figure 2. On Figure 3, we can see that the 8 axial groove section and the 9 tangential groove section form a depression on the external surface of the 1 cylinder part of the cap; also there is a female thread inside the 1 cylinder part of the cap. There are two 7 T-shaped grooves; they are placed symmetrically, diametrically opposing each other.

The left side of Figure 4 shows the cross-section of an implementation example of the cup; the right side shows its view. Here, the 14 pin has circular cross section and connects to the 6 cap receiving part. The cup is depicted upside down on the image; in which orientation it can be fixed to the 15 bottle. On the left side of the figure, the 10 retardant knurling implemented at the 3 cup mouth on the inside of the 5 cup wall can be seen, as well as the 13 liquid level measuring stripe, on which, in this case, three measuring markings can be seen: at one, two and three deciliters. On the right side of the image, it can be seen that on the external surface of the 5 cup wall, from the 4 bottom of the cup until the one-third of the cup height, there are 12 knurlings ensuring adhesion.

Figure 5 shows the 15 bottle in front view, and it can be seen that the 11 drop-retardant knurling of the bottle is in the stripe of the 15 bottle where the 15 bottle can connect with the 3 cup mouth when the cup, the cap and the 15 bottle is assembled. On the 15 bottle, it also can be seen that there are two stripes of 12 knurlings ensuring adhesion: one of them is under the 11 drop-retardant knurling of the bottle and the other is on the bottom of the bottle in the stripe running along the perimeter.

In an implementation example of the cup with cap for bottles according to the utility model, the volume of the 15 bottle is one-and-a-half liters, the volume of the cup is three deciliters, the 10 drop-retardant knurling of the cup and the 11 drop-retardant knurling of the bottle is a two centimeter wide stripe at each piece; the 12 knurlings ensuring adhesion on the cup and on the 15 bottle is a ten centimeter wide stripe of knurlings of criss-cross pattern.

In an implementation example of the cup with cap for bottles according to the utility model, the volume of the 15 bottle is half liter, the volume of the cup is two deciliters, the 10 drop-retardant knurling of the cup and the 1 1 drop-retardant knurling of the bottle is a one centimeter wide stripe at each piece; the 12 knurlings ensuring adhesion on the cup and on the 15 bottle is a five centimeter wide stripe, consisting of axial knurlings.

The cup with cap for bottles according to the utility model has many technical advantages over the prior art. Thanks to the bayonet catch, the inner geometry of the cup is simpler, so it can be cleaned more easily. Thanks to the 10 and 11 drop-retardant knurlings, leftover drops do not pour out from the cup, not even if the cup is turned upside down and with its help, the cap is screwed onto the bottle. The 12 knurlings ensuring adhesion make handling of the bottle and the cup easier.
