Description

This utility model relates to a disposable cup worn on a spray gun for preparing and applying paint and preserving unused or unused paint. It is known that painters using paint spray guns have to deal with difficult operations when preparing paints and transferring them from one container to another, which creates the risk of spills and loss of paint. It is also known that in connection with the growth of labor costs, all employers strive to find solutions that increase the speed of operations. In connection with the foregoing, various solutions have been developed for disposable glasses or elastic disposable bags containing paint during preparatory and painting work with the spraying of paint and varnish material. These solutions reduce the time spent cleaning equipment and reduce the use of solvent-based cleaners, which are often environmentally friendly. The closest analogue of the claimed industrial design is a disposable cup, disclosed in document EP 0987060 A, 03/22/2000, in particular, a gravity spray gun for preparing, applying and preserving paint, having a cylindrical body, a cover for closing the body, the body has the bottom with the side intersected by the opening of the air channel, the cover has an outlet for paint, which is mounted directly on the spray gun, on the wall of the bottom of the glass there is a locking device which allows, when the closing device of the air channel is open, air to enter to occupy the space of the internal volume created by the expended paint during painting, and when it is closed, close, at least in a liquid-tight manner, the opening of the air channel to form a container for paint preparation. It remains to solve the problem of unspent paint. These paint residues do not need to be stored for a long time, but used in the near future, for example, at the same facility.

It remains to find a solution for the loss of paint, which spills out of the hole due to sudden movements and turns or a sharp tilt by the painter.

The overall goal of this utility model is to address these shortcomings and create additional benefits based on its own characteristics.

To this end, the present utility model relates to a disposable cup for preparing paint and its application with a spray gun. This glass, worn on a spray gun, in particular a gravity spray gun, and having a body, for example, of a general shape of a truncated cone with a bottom in which an air outlet is made, and a lid, the outlet channel of which is mounted on an adapter that will be mounted or mounted on or mounted on a spray gun, characterized in that the glass has on one of its walls a lockable air channel device with a movable part, which, when open, allows enter the glass to fill the empty volume and, when closed, seals the air outlet, making it at least liquid tight, so as to obtain a container for preparing paint, and close the paint outlet with a second movable part, preferably identical to the first, to create containers that protect the paint from contact with air, for storing unspent paint.

A disposable cup for preparing and applying paint by spraying has the form of a container, the housing 1 of which has, for example, a conventional cylindrical shape or a truncated cone shape having a side surface 2, a bottom 3 and a cover 4.

The bottom 3 is at some distance from the lower edge due to the presence of the lower peripheral annular edge 5 in the form of an extension of the bottom 3. The lateral surface 2 protrudes to ensure stability when the glass is placed flat horizontal support. A hole 6 passes through the bottom 3, forming an air channel, which allows air intended to replace the expended ink in volume to flow and paint to flow. This hole 6 of the air passage channel may be central or different, as shown in the figures. It is proposed to equip this hole with a closing device 7 of the air channel.

The side surface 2 is made smooth and has a graduated scale 8, passing along the height of the glass in the form of successive calibrations 9, engraved, printed or made in the body of the glass. The side surface 2 may have several reinforcing ribs 10, as shown in figure 1.

On the upper side, the housing 1 is closed by a funnel-shaped lid 4, which in its central part has an outlet channel 11, slightly tapering and in the shape of a cone. The cap 4 is screwed from its bottom onto the upper part 12 of the side surface of the cup body 1, on which several consecutive ribs 13 are formed, forming a thread, for example, a burst, which takes the corresponding threaded formation of the cap 4 when screwed onto the cup body. The lid has an inwardly facing shoulder 14, as shown in FIG. 8, which supports a disk-shaped filter 15 around the circumference. The filtering part is surrounded around the perimeter by an annular connection 16 (figure 3).

The glass is put on a spray gun, preferably, but not exclusively, on a gravity spray gun 17, using a transition piece 18. This transition piece 18 can be, for example, a hollow part, wound one end or assembled or attached to a protrusion 19, for example, a threaded protrusion of the gun, and a receiving central conical outlet channel 11 of the cover 4 with a tight conical fit. Of course, you can use many other connecting means, as well as other existing or future transitional parts.

Such a connection with a tight conical fit is quite difficult to disconnect, and it is tight enough for use and the movements of the painter during operation.

Now will be considered a closing device 7 of the air channel.

The closing device 7 performs the normal function of a valve, letting in air when painting, that is, when the glass is empty, and closing the hole 6 of the air inlet channel when the glass is used as a container for preparing paint.

In the valve type closing device 7, a movable member 20 and a valve body 21 are used in which the movable member 20 is moved between a position in which the opening 6 is closed and a position in which the opening 6 is open.

Preferably, but not limited to, the movable element 20 is fixed in the valve body 21 in each of its characteristic positions, namely, in the closed position and the open position, and freely moves between these two positions when it is controlled.

For this, the hole 6 of the air passage in the bottom 3 is surrounded by a hollow cylindrical base 22, reinforced by radial ribs 23, which serves as a valve body, the height of which remains less than the height of the plane defined by the upper crest of the annular edge 5. Due to this, the glass is placed on a horizontal flat surface , maintains stability in the corresponding vertical second position for the preparation of paint.

This hollow cylindrical base 22 is the channel through which the movable part 20 moves.

In this base 22, forming a channel, when it is molded, an annular rib 24 is protruded from the inner side surface. An annular rib 24, referred to as a flap accommodating rib, provides a flip placement each time for the movable member 20 manually moved within the valve channel 22. Due to its shape, this part is called valve plug 25. This valve plug 25 allows the valve to open and close in two precise positions. The first position is the closed position, in which the tip of the plug enters the hole 6 of the channel for the passage of air in the bottom 3, so as to close it tightly, without protruding from the inside of the bottom 3, and is held in this position by jumping. The second position, called the open position of the channel, is the position in which the tip of the plug exits the hole 6 of the channel for the passage of air in the bottom 3 of the glass and is held in this position by the second popping-up ledge. These positions are shown in figures 4 and 5.

Of course, installing the plug in the above positions can be done in other ways: using screw stoppers, notches, turning a quarter of a turn, etc.

An example embodiment of the valve plug 25 is shown in perspective in FIG. 7.

In this embodiment, the valve plug 25 is a body, for example, hollow, of a conventional cylindrical shape, having at one end a disk-shaped upper end with an outer upper edge 26 having a larger diameter than the body itself and forming an upper mounting arm, and on the other end, the end surface of the lower end, ending with a final formation, closing the hole 6, made in the bottom 3, without protruding its tip from the inner side of the bottom of the glass, and making close contact with part of this hole Stia 6 for sealing.

In order for the air to enter in the open position, there is a play or clearance between the upper parts of the channel 22 and the plug 25. This backlash can be obtained by increasing the inner diameter of the upper part of the channel 22 or correspondingly decreasing the diameter of the upper part of the plug 25, or both simultaneously. In order to hold the plug 25 in a central position, on a higher part of the inner side surface of the channel 22, three or four centering longitudinal protrusions are provided, for example, in a semi-cylindrical shape, 27 of corresponding thickness.

Conversely, these centering protrusions may also be on the side surface of the plug 25.

In its lower part, the cork ends with a closing formation, for example, a tapering finger-shaped protrusion 28, the shape and size of which are selected to provide a complete liquid tight seal for opening the channel opening 6 in the depressed position when the movable part or cork in the channel is in the lower closed position.

Of course, this shape may vary depending on the shape of the hole, provided that the plug in its closed position closes this hole.

Between the two ends of the plug 25 passes a body, which is usually cylindrical in shape with a side surface having annular grooves 29 and 30, designed to populate in them an annular protruding rib 24 of the channel 22 of the valve to accommodate this rib in one or the other groove of the valve plug 25, which corresponds one of the stop positions in the open or closed position.

Obviously, the shapes can change and, in particular, be reversed without changing the overall function, that is, the protrusions can be on the side surfaces of the plug 25, and the grooves are made on the side surface of the valve channel 22.

The cork is made of plastic. The cork is full or hollow, which provides a certain degree of elasticity.

In addition, the closing finger 28 can punch or tear or punch or break through the membrane, film or a local weak or weakened point or area of the bottom side 3, which closes the hole 6 at the manufacturing stage and at first use. To this end, the finger 28 or the end formation will have a corresponding shape for this function, for example, a more conical or pointed end, or a similar or any other shape.

On the lateral side of the valve plug 25, behind its lower end, two diametrically opposite longitudinal cutouts 31 and 32 are made, extending from the lower end side in length. The length of these cutouts is such that they pass through the first groove 29, corresponding to the locking position for closing, and further beyond it, not reaching the second groove 30. The depth of the grooves 31 and 32 makes their base below the base of the first groove 29 to form an air passage under an annular protrusion 24 when the valve plug 25 is in its first pushing position, i.e., in the closed position, or when the first protrusion — the annular rib 24 — is engaged in the first groove 29.

It is clear that the stop positions for closing and opening correspond to the two main uses of the proposed glass, i.e., on the one hand, as containers for preparing paint and, on the other hand, as glasses for the paint of a spray gun, respectively.

To keep the cork in its two positions, all kinds of ratchet or clamping mechanisms or mechanisms with a snap-in are possible. In addition, simply reversing the forms in their function or position does not change the utility model.

In addition, the internal device of the end of the outlet channel 11 of the cover 4 can be made so that it includes a plug 33 of the second valve as a closing element used from time to time, thereby providing the possibility of additional use of the proposed glass, namely: protection and preservation of any quantities unspent paints specially prepared for the work performed. For this purpose, a special internal arrangement of the exhaust channel 11 is not required. Then a sufficiently fitted seal is used between the two parts, providing temporary tightness during the required storage period.

Preferably, as the second plug 25, a plug identical to plug 33 is used. Its cost is low since it is the same plastic part made by injection molding.

Preparation of paint is carried out in a glass with the valve of the air channel in a closed position, not permeable to liquids or with an opening closed by a membrane or a film or wall of a smaller thickness. For this purpose, the container, when placed on a flat horizontal surface, is in a stable position due to the protruding annular edge 5, and the painter can easily perform the preparation using a graduated scale 8, which is located on the side surface of the glass case.

In order to start painting, the painter just needs to close the glass with its lid with a filter, then put the spray gun on the outlet channel with its transitional part, which can be done with a simple and quick movement due to the conical fit, turn the spray gun with the glass mounted and move it the valve plug 25 in the open position, i.e., the protrusion pops up into the first groove, namely, into the popping groove. Thus, the painter can easily work without worrying about leakage of paint or untimely exit of paint through the upper side when the glass is tilted.

In addition to the disposable nature of the proposed glass, which gives a number of advantages, it should be noted the ease of use and time gain during preparation due to its double use and its role as a paint can for preserving unspent paint, ready for future use.

The central protrusion of the valve 22 can be closed with a closing movable valve element 20 as a cover. In this case, a covered part made as a cover, which is a central sealing part, which extends downward with a common conical shape ending in a sealing formation, for example, a finger, designed to perform this function, may be suitable. In the same way, the sealing finger tightly enters the hole 6 when this cover is in the lower position, without protruding from the bottom side of the base. Characteristic positions can be fixed due to the interaction between the grooves and the annular protrusions, as described above, or using other equivalent forms. The air passage is carried out along the longitudinal channels in the cylindrical protruding part or other equivalent means of implementation.

Figures 9-13 show other embodiments of a lockable air channel device.

Figure 9 shows an alternative embodiment of a type of plug 34, for example, screwed, the lower end of which ends with a closing finger 35 for the channel opening 6. The body of the plug 34 has a common T-shape with a cylindrical lower part 36 placed in a hollow cylindrical base 22. The body of the plug continues with a cylindrical head part 37 of a larger diameter, having an even larger part on top. The body of the plug 34 has a central inner channel 38 for the passage of air and its entry into the cup, which is closer to the lower end divided into two branches 39 and 40. The upper position corresponds to the open position of the air passage during painting work, and in the lower position, the plug provides closing of the hole in the bottom of the glass with a closing finger 35.

Holding the plug 34 in the desired position, its direction down to the closed position and locking in this position is carried out, for example, using a screw thread. To this end, a protruding external thread 41 is made on the lateral surface of the cylindrical part 36 of the plug, which engages with an internal thread 42 made on the inner side surface of the cylindrical protrusion 22. Full twisting into this protrusion corresponds to a closed position in which the plug can be held by the popping protrusions or any other means, for example, a dog. The same methods apply to the upper open position. You can use a quick closing and opening device with a quarter turn rotation or any other.

According to one feature of the utility model, when the cork is inserted, its upper tip does not protrude beyond the surface defined by the outer upper crest of the edge 5 protruding from the bottom of the glass.

Figure 10 shows another embodiment of the plug 43 with the lower closing finger 35. In this alternative, the air is admitted at least one or, preferably, two transverse channels 44 made in the base of the cylindrical receiving protrusion 22 at the bottom of the glass . As in the previous embodiment, the transition to the closed lower position is carried out by twisting, i.e., using the external thread 41 on the side surface of the cylindrical part of the body of the tube, which engages with the internal thread 42 on the inner side surface of the cylindrical protrusion or vice versa (vice versa - lat.).

An additional alternative embodiment, shown in figures 11-13, is a rotating between a closed position in which it is tilted and hidden in the thickness of the bottom wall of the glass, and an open position in which it stands upright.

The body of the movable pivoting member 45 in this additional alternative embodiment has the general form of a whistle mounted to pivot in the cavity 46 formed in the bottom wall 3 of the glass, using two transverse tides 47, for example, clamped in the corresponding opposite slots. In the longitudinal direction, this body intersects with a channel 48 for the passage of air, which in the open position goes directly to the hole 6 in the base of the cavity 46 (or next to it), which is the channel hole in the bottom wall 3 of the glass, as shown in the drawings. The body of the tilting movable element 45 consists of a linear elongated part 49 and a thickened part 50. In the lower thickened part 50, a locking and closing pin 51 is provided for closing the hole 6 in the wall 3 of the bottom of the glass in a closed tilted down position and for holding the movable rotary element 45 in this position. The height of the finger 51 is such that the tip of the latter will not protrude from the inside of the bottom, and at best it will be flush with it. The movable pivoting member 45 of this air channel closure device has a laterally protruding unit 52 that acts as a gripping means, as a pivot stopper in the open position, as shown in FIG. 12, and as a closure stopper for the nozzle outlet if it is desired to preserve paint as shown in figure 13.

The shape of the fingertip provides less resistance to work and sufficient tightness.

For placing the linear part 49 in a downward inclined position corresponding to the closed position, for example, a corresponding cavity 53 is provided, cut in the thickness of the bottom wall 3. Obviously, for this purpose, the wall 3 of the bottom should be thicker.

The height of the gripping unit 52 will remain below the value at which it could extend beyond the surface defined by the upper ridge of the annular edge 5 to ensure the stability of the glass in the position for preparing the paint.

For the body of the glass, consider using translucent and opaque materials to filter or protect against ultraviolet rays. This point is important in the case of photosensitive products.
