Description

Introduction The invention relates to a device for juicing citrus fruits. In particular, the invention relates to a device for manual, convenient and safe juicing. State of the art and disadvantages Devices for manually juicing citrus fruits such as oranges or lemons are already known. They comprise a cylinder open at both ends and at least one opening on the side. When the juicer is inserted into a citrus fruit, its juice flows into the interior of the cylinder through the base and the side opening. By tilting the fruit, the juice can be poured out from the top. This process can be repeated several times, provided that not all the juice is extracted, for example, by squeezing the fruit immediately. A disadvantage of the known solutions, however, is that with repeated, staggered extraction, the juice in the cylinder comes into contact with the outside air and can thus oxidize; this particularly affects vitamin C, which is known to be present in citrus fruits but degrades over time. Furthermore, the fruit, which is usually rounded at the bottom, cannot stand upright; if it tips over, the liquid already collected in the cylinder spills out. For the same reason, the fruit should be held in the hand while squeezing; however, this quickly leads to the hand becoming wet with juice, which is undesirable. Problem of the invention and solution The invention is therefore based on the objective of providing a device and a method which avoids the disadvantages of the prior art. The invention is intended to provide a juicer that, during multiple, time-delayed uses, keeps the juice in the freshest possible state, prevents the fruit from tipping over, and prevents unwanted wetting of the hand when using the juicer. The problem is solved by a device according to claim 1. Advantageous embodiments can be found in the dependent claims, the following description, and the figures. Description The device is designed for juicing citrus fruits, particularly lemons or oranges. With appropriate adjustments to the dimensions, however, the device can also be used with larger (e.g., grapefruits) or smaller (e.g., tangerines) citrus fruits. The device comprises a cylinder open at both ends and with at least one opening on each side. The cylinder's height is, for example, 7 ± 2 cm, its diameter at the top is, for example, 25 ± 5 mm, and its wall thickness is, for example, 3 ± 1.5 mm. The device is characterized by a seal that can be inserted into the upper end of the cylinder and locks it in a liquid-tight manner. The seal separates the interior of the cylinder containing the liquid from the outside air, so that already squeezed juice stays fresh longer and does not oxidize. Furthermore, this ensures that if the fruit tips over, the juice remains in the cylinder and is not spilled. According to the invention, the device further comprises a bowl-shaped holder designed to support at least the lower third of the citrus fruit. The holder thus ensures that the fruit remains securely in an upright position during and after juicing, which helps prevent unwanted leakage of the juice contained in the cylinder. Furthermore, the fruit does not need to be held in the hand when using the device; this avoids wetting the hand with the liquid during juicing. The invention thus avoids the disadvantages known from the prior art. The invention provides a juicer which, during repeated, time-delayed use, keeps the juice in the freshest possible state, prevents the fruit from tipping over, and prevents unwanted wetting of the hand when using the juicer. Various embodiments of the invention are described in more detail below. In one embodiment, the cylinder has two opposing, slot-shaped lateral openings. The slots are particularly vertical and have a width of 1.0 ± 0.5 cm and a height of 2.5 ± 1 cm. The juice enters the interior of the cylinder through the slots, where as it accumulates. The slots cover approximately 30% of the circumference. A larger proportion of slots can weaken the mechanical stability, while a smaller proportion can result in the liquid entering too slowly. In one embodiment, the lower end of the cylinder has a rim designed to cut through the citrus fruit. This makes it easier to drive the cylinder into the interior of the citrus fruit, since the center of a citrus fruit often contains areas with a higher lignin content (core, etc.). In one embodiment, the cylinder tapers from top to bottom. This makes it easier to drive into the fruit. When the cylinder is upright, the angle to the vertical is, for example, 8 ± 5°. The difference in diameter between the top and bottom edges of the cylinder is, for example, 5 ± 2 mm, or 15 ± 5%. In a further embodiment, at least part of the upper half of the cylinder has a thread on its outer surface, making it easier to screw into the citrus fruit. The thread is preferably a coarse thread with a pitch of 20–30° and a projection of 3 ± 1 mm beyond the cylinder's outer surface. The thread also ensures that
