Description

Device, head piece for closing a bottle of the device and system comprising the device
Technical Field
The present invention relates to a head piece/cover piece for closing a bottle and a device having a head piece according to the present invention.
Background
As described below, EP 3 501 630B1 discloses a device for producing, preserving and discharging creamy food products, in particular whipped cream, and hot, foamed and sauce-like food products, which are located in an inner cavity of the device, wherein the device essentially consists of a bottle, a head part, a handling element and a gas capsule holder. In detail, the bottles are initially filled with the respective food product to be sprayed and subsequently closed with a head piece, wherein a piston sleeve for receiving a dispensing piston and a nipple for receiving a gas capsule holder are typically constructed integrally with the remainder of the head piece, wherein an outlet nozzle for targeted, specific discharge can be arranged on the dispensing piston. In this case, the food product or the medium to be sprayed is initially located in the bottle in liquid form, wherein a gas, preferably N, is introduced from a gas capsule that can be arranged in a gas capsule holder 2 O or CO 2 Is introduced into the interior of the apparatus and the pressure in the interior of the apparatus is raised so that the gas particles are dissolved in the food product. Upon dispensing or upon spraying, the dissolved gas expands. Thereby causing the food to foam or causing the food to convert to a creamy or foamy or sauce-like state.
In the case of devices for dispensing fluids that are customary on the market, the problem is that the head part is produced as a cast part at very high cost, which results in high costs in its production, or for the sake of cost reduction, is produced from plastic, wherein such a head part made from plastic is suitable for use in a dishwasher only to a limited extent due to the temperature change resistance of the plastic and becomes brittle over time, as a result of which the risk of accidents during use of the device increases due to the pressure in the interior of the device. Furthermore, such a head piece must always be redesigned and manufactured from scratch for new devices, thereby incurring high development costs.
SUMMERY OF THE UTILITY MODEL
It is therefore an object of the present invention to provide a cost-effective and modularly usable head piece for closing a bottle of a device for dispensing a fluid, wherein the head piece is preferably temperature-change resistant and also chemical resistant and is therefore designed to be dishwasher-compatible and robust.
To achieve the object, a head part is proposed. In order to close the bottle of the device for producing, preserving and discharging a creamy food product and/or soda, the head part comprises a piston sleeve and a connecting piece, wherein the piston sleeve is designed to receive the dispensing piston and the connecting piece is designed to receive the gas capsule holder, wherein a push-out plate and a piercing pin holder with a piercing pin can be arranged in the connecting piece. According to the invention, the piston sleeve and the adapter protrude from the head piece base, on which a lever bridge (hebelbrhucke) is arranged directly, which lever bridge is provided for supporting the actuating element of the device. That is to say, the rod bridge is not arranged on the connecting piece or on the piston sleeve, so that the rod bridge itself can be designed as a component with great mechanical stability. The following advantages are also obtained: in particular the bar bridge can be made as a separate component, so that it can be easily adapted to different bottles or applications.
The lever bridge preferably serves to support the actuating element for rotational movement.
The lever bridge can be connected to the dispensing piston by means of an actuating element.
A creamy food product is also to be understood as meaning in particular a sauce-like and/or foamed food product. Furthermore, the head element according to the invention may also be used in soda siphons, that is to say in particular in devices for discharging soda water. In general, the head piece according to the invention is suitable for closing a head piece of a bottle of a device for discharging or for discharging/ejecting an ejection medium.
The head part base of the head part can be used as a flexibly usable carrying element.
In a preferred embodiment, the head part base has a first recess, a second recess and a third recess, in which the piston sleeve, the nipple and the rod bridge are arranged at least in some regions. This embodiment makes it possible to manufacture the head part base, the piston sleeve, the connecting piece and the rod bridge separately from one another, so that the head part base advantageously forms a platform/foundation for a diverse design of the piston sleeve and/or the connecting piece and/or the rod bridge. In this case, it is preferred that the first recess for at least partially receiving the piston sleeve and the second recess for at least partially receiving the connecting piece are each designed as a through-opening, preferably as a through-hole, while the third recess for at least partially receiving the rod bridge is preferably designed with a rectangular or quadrangular or triangular or circular cross section, which has proven advantageous from a manufacturing point of view.
Preferably, the third recess is not designed as a through opening, which again contributes to ensuring the tightness of the device. The third recess can be designed, for example, as a blind hole, preferably as a blind hole.
In order to prevent the injection medium from accidentally flowing out of the device, in a preferred embodiment the first recess and the second recess each comprise a groove for receiving a sealing element, preferably an O-ring, wherein the first sealing element is arranged on the piston sleeve and the fifth sealing element is arranged on the nipple.
In a preferred embodiment of the invention, the piston sleeve is pressed or glued or screwed into the first recess and the nipple is pressed or glued or screwed into the second recess, which enables a particularly secure connection of the piston sleeve and the nipple to the head part base. In this case, the piston sleeve and the adapter each preferably comprise a fold region, which in the pressed-in or glued-in or screwed-in state of the piston sleeve and the adapter is arranged in each case in the region of the side of the head part base facing away from the third recess, in order to provide a further safety possibility for the connection between the piston sleeve or the adapter and the head part base.
The fold regions are each designed to be deformable in order to ensure a permanent connection.
In other words, the piston sleeve and the adapter are first inserted into the corresponding recesses and then the respective flanging regions are flanged such that the respective flanging regions bear against the head part inner surface of the head part base facing away from the third recess, so that a permanent connection between the piston sleeve and the head part base and the adapter and the head part base is ensured, as well as an additional protection against rotation.
The following advantages are obtained by this folding: a relatively small wall thickness can be used for the head part base, whereby a lower cost and a lower weight are achieved compared to the known solutions. The following advantages are also obtained: in the case of damage in a pressurized device, for example due to dropping of the device, the nipple or the piston sleeve is always still connected to the head piece base by the fold or by the form-fit formed, so that there is no uncontrolled risk to the user due to explosive detachment from the head piece base.
Alternatively or additionally, in a preferred embodiment of the head piece according to the invention, it is provided that the piston sleeve and/or the connecting piece are welded to the head piece base by means of a gas-tight, preferably low-deformation weld seam. The result is a mechanically particularly stable connection. Furthermore, sealing elements for sealing the piston sleeve or the connector piece with respect to the head piece base can be dispensed with due to the gas tightness of the weld seam. In this case, the respective weld seam can be arranged on an outer side of the head part base which, when the head part closes the bottle, points outward or away from the bottle, or the respective weld seam can be arranged on an inner side of the head part base which is opposite the outer side.
In a further preferred embodiment of the invention, the lever bridge is substantially L-shaped or branched and has a main arm and an auxiliary arm, wherein the main arm is arranged in the third recess with an end of the head part base side configured corresponding to the third recess and has a bore on the opposite end for receiving a pin for connection to the actuating element.
Preferably, the head member base side end portion of the main arm is pressed or stuck or screwed into the third recess of the head member base or is welded with the head member base.
In this case, the actuating element, which is preferably in the form of a lever or a push button, is pressed by a spring element onto the dispensing piston, as a result of which the spray medium can be dispensed from the bottle.
In a particularly preferred embodiment of the head part according to the invention, it is provided that the secondary arm is arranged in the region of the head part base and engages with its free end into a nipple recess arranged on the nipple for preventing the nipple from rotating. Thereby, a possible rotation of the adapter tube due to screwing in or out of the gas capsule holder can be avoided. The arrangement of the secondary arm in the region of the base of the head part proves to be particularly stable and space-saving here.
In a further preferred embodiment, the head part base is at least partially surrounded by the head part cover, as a result of which a more attractive, aesthetically pleasing appearance of any configuration can be achieved. Preferably, the head covering comprises openings for the passage of the piston sleeve, the nipple and the rod bridge in the region of the three recesses of the head base, so that on the one hand an unproblematic arrangement of the head covering in the region of the recesses is possible and on the other hand the head covering can be easily removed for cleaning the head covering.
In a further preferred embodiment of the invention, the head part base is designed as a deep-drawn part, preferably made of stainless steel. This yields the following advantages: the head part base forms a relatively advantageous and easily manufacturable base platform on which a plurality of different embodiments of the piston sleeve, the nipple and the rod bridge can be arranged, and a plurality of different shapes of the head part cover can also be used.
Furthermore, an apparatus for ejecting an ejection medium by means of a head member according to the invention is proposed, the apparatus comprising: a bottle openable and closable by means of a head member, the bottle forming an inner cavity for accommodating a spray medium; an actuating element, preferably in the form of a lever, for actuating the device, which is mounted on the lever bridge; a gas capsule holder received in the nipple; a dispensing nozzle arranged on the dispensing piston arranged in the piston sleeve, through which nozzle a spray medium can be ejected from the interior of the bottle when the device is actuated; and a thrust plate arranged in the nozzle and a piercing pin holder with a piercing pin.
In a preferred embodiment of the device according to the invention, a lever cover is arranged on the actuating element in order to be able to ensure, on the one hand, a large gripping surface and, on the other hand, a more attractive or aesthetically pleasing appearance, which can be designed as desired.
In a preferred embodiment of the device according to the invention, provision is additionally or alternatively made for a bottle cover to be arranged on the circumference of the bottle. This also ensures a larger grip surface and a more attractive or aesthetic appearance, which can be designed as desired.
For using the device, an exchangeable, gas-filled gas capsule can be arranged in the gas capsule holder in order to establish a fluid connection between the gas capsule and the device.
In other words, in the device it is provided that, in the operating state of the gas capsule, the gas capsule is held in the gas capsule holder and a fluid connection of the gas capsule to the device is ensured in that the gas capsule is pierced by means of a piercing unit which comprises a piercing pin and a piercing pin holder, wherein the gas capsule forms a gas reservoir, wherein the gas is almost completely transferred from the gas capsule into the device interior after the gas capsule has been pierced, so that the gas capsule can be removed from the device after piercing and shaking. In another case, the gas capsule can also be held in the device until the end, wherein no additional use is thereby made for the user, since the gas is already introduced into the inner space of the device. It is obvious that the use of the device for spraying presupposes that the spraying medium in the interior of the device is sprayed, since otherwise only gas is sprayed out.
The gas which can be used is preferably dinitrogen monoxide (N) 2 O) or nitrogen (N2) or carbon dioxide (CO) 2 ) Or argon (Ar). Correspondingly, according to the invention, a system is also proposed, which comprises a device according to the invention and a replaceable, gas-filled gas capsule, wherein the gas is nitrous oxide (N) 2 O) or nitrogen (N) 2 ) Or carbon dioxide (CO) 2 ) Or argon (Ar). Of course, the expression gas should be understood as possiblyAnd unavoidable or negligible contamination of the substrate is included therein.
In a preferred embodiment, it is provided that, in the closed state of the gas capsule, the gas has a pressure of 50bar to 200bar, wherein this pressure is dependent of course on the structural form of the gas capsule.
The gas capsule may, but need not, be fluidly connected to the apparatus and held in the gas capsule holder for a correspondingly long time. However, the gas capsule is actually removed at the latest after all the ejection medium has been ejected and/or after the device has been completely pressureless.

The non-return valve 23 interacts with the pressure-limiting valve piston 21 for the controlled discharge of gas flowing in the gas flow direction 32 via the gas channel 27 from the gas capsule 41, wherein the pressure-limiting valve piston 21 is inserted in a gas-tight manner by means of a fourth sealing element 22 and a sixth sealing element 40, see fig. 2 and 3 in more detail.
An "L-shaped" or "branch-shaped" lever bridge 18 is arranged on the head part base 8, said lever bridge comprising bores for receiving the bushing 37 and the pivot pin 17, wherein the pivot pin 17 is used for connecting the actuating element 16. Here, a recess arranged in an actuating element 16 in the form of a lever, on which a dispensing piston upper part 11 is arranged, which has an outlet nozzle 19 arranged thereon, rests on a spring element 15, so that, when the lever 16 is actuated, a pressure can be applied to the dispensing piston upper part 11 and to the spring element 15 in the form of a pressure spring, as a result of which ejection of the spray medium 5 can be achieved.
In detail, the spring element 15 is compressed by means of the lever 16, so that the upper dispensing piston part 11 is moved together with the lower dispensing piston part 12, wherein the ejection opening 20 for the ejection medium 5 is opened in the actuated state, wherein the ejection medium 5 can enter the longitudinal bore through the transverse bore and continue to flow through the ejection opening 20 out through the outlet nozzle 19, which is arranged on the upper dispensing piston part 11 via an outlet nozzle connection 33 having an outlet nozzle connection seal 34.
It is also possible to use, instead of a compression spring, a damper in the form of a rubber element which can be compressed under pressure and re-expanded in the unloaded state. This damper is finally used to close the outlet opening 20 in the same way as a pressure spring.
Fig. 4 shows in detail the respective pressing-in direction or screwing-in direction or insertion direction of the piston sleeve 35 into the first recess 48, the respective pressing-in direction or screwing-in direction or insertion direction of the rod bridge 18 into the third recess 50, and the respective pressing-in direction or screwing-in direction or insertion direction of the nipple 24 into the second recess 49 of the head part base 8, wherein it can also be clearly seen that the first recess 48 for receiving the piston sleeve 35 and the second recess 49 for receiving the nipple 24 are through openings, preferably through holes, while the third recess 50 for receiving the rod bridge 18 is designed in the form of a groove.
The piston sleeve 35 and the connecting piece 24 are preferably designed as swivel-type parts. In order to ensure a gas-tight connection, a first sealing element 13 is arranged on the piston sleeve 35, which engages in a first groove 51 of the first recess 48, and a fifth sealing element 25 is arranged on the nipple 24, which engages in a second groove 52 of the second recess 49. Since the piston sleeve 35 and the connecting piece 24 are preferably designed as swivel-type parts, the first sealing element 13 and the fifth sealing element 25 are preferably both O-rings.
It can also be clearly seen that the lever bridge 18 is designed "L-shaped" or "branched", whereby it is composed of a main arm 54 and an auxiliary arm 55. A bore 53 for receiving the bushing 37 and the pivot pin 17 for connection to the actuating element 16 is arranged in the region of the end of the main arm 54.
Fig. 5 shows the piston sleeve 35, the rod bridge 18 and the connecting piece 24 in a state of being arranged on the head piece base 8, wherein the main arm 54 is arranged in the third recess 50 with the end of the head piece base side configured corresponding to the third recess 50. The selected lever connection 46, in which the end of the main arm 54 on the head part base side is arranged in the third recess 50 of the head part base 8, is preferably crimped or glued or screwed or welded. The selected lever connection 46 ensures that even very high forces can act on the lever bridge 18 via the actuating element 16. In the case of welding, possible welding residues can be ground off after the lever bridge 18 has been arranged on the head part base 8. It can also be clearly seen that the secondary arm 55 arranged on the head piece base side engages with a free end into the socket recess 47 arranged on the socket 24 for preventing a rotation of the socket 24, whereby a possible rotation of the socket 24 out of the head piece base 8 due to screwing in and out of the gas capsule holder 29 can be avoided.
In detail, the piston sleeve 35 and the adapter 24 each also have a respective folding region 44, 45, which in the pressed-in or glued-in or screwed-in state of the piston sleeve 35 and the adapter 24 is arranged in the region of the side of the head part base 8 facing away from the third recess 50, that is to say in the region of the interior 4 of the bottle 2. Here, the folding regions 44, 45 are each formed in such a way that, after the piston sleeve 35 has been arranged in the first recess 48 and the adapter 24 in the second recess 49, a permanent connection is ensured by folding the folding regions 44, 45, for which purpose reference is also made in detail to fig. 8 and 9.
Additionally or alternatively, the piston sleeve 35 and/or the adapter 24 can also be welded to the head piece base 8 by means of a gas-tight, preferably low-deformation weld seam (not shown).
Fig. 6 and 7 show the assembly of the head part 7 according to the invention, wherein in a first step the lever bridge 18 is connected to the head part base 8 by means of a lever connection form 46 and the head part cover 10 is subsequently slipped onto the head part base 8. The head part cover 10 has three openings, namely a first opening 56, a second opening 57 and a third opening 58, in which the piston sleeve 35 can be received, the connector 24 in the second opening and the rod bridge 18 in the third opening. In detail, the head part cover 10 is initially fitted to the head part base 8 such that the stem bridge 18 protrudes from the third opening 58; and then, according to fig. 7, the piston sleeve 35 is arranged in the first recess 48 through the first opening 56 and the nipple 24 is arranged in the second recess 49 through the second opening 57. Finally, the folding regions 44, 45 are folded according to fig. 9, so that a permanent connection is ensured.
Fig. 10 shows an exploded view of a further embodiment of the head part 7 according to the invention, without the head part cover 10, wherein the lever bridge 18 is constructed approximately linearly, that is to say without the secondary arm, solely on the basis of the primary arm 54. In this case, the end of the main arm 54 opposite the bore 53 is pushed into the recess 50 of the head part base 8, which is formed in the form of a slit in this embodiment, and then welded or adhesively bonded to the head part base 8.
In this case, as can also be seen clearly in fig. 10, in a preferred embodiment at least one relief slot 59 is arranged on the head base 8 in the region of the internal thread of the head part 7. The relief slit 59 here acts as a guard or safety device to prevent the head 7 from suddenly separating from the bottle 2 when the device 1 is under pressure in an attempt to unscrew the head.
Fig. 11 also shows a ring seal 60, which is arranged in another embodiment in the head part 7 and serves to seal the threaded connection between the internal thread 9 of the head part 7 and the external thread 6 of the bottle 2.
Fig. 12 shows a side view of the assembled head part 7 or head part base 8 of the further embodiment of fig. 10, wherein the prevention of rotation of the adapter tube 24 is achieved in that a first flat portion 61 of the adapter tube 24 engages into a second flat portion 62 of the second recess 49 of the head part base 8, which flat portion corresponds to the first flat portion. In detail, the peripheral surface region of the nipple 24 has a first flat portion 61 and the second recess 49 designed to receive the nipple 24 has a corresponding second flat portion 62, see also fig. 10.
In the sectional view in fig. 13, which is shown in accordance with section linebase:Sub>A-base:Sub>A in fig. 12, the flattened area of the circumferential surface of the connecting piece 24 and the corresponding flattened area in the second recess 49, which is formed in the head piece base 8, can be seen clearly. In detail, the positive locking formed by the first flat portion 61 and the second flat portion 62 prevents a possible rotation of the nipple 24 inserted into the second recess 49, thereby achieving an anti-rotation.
