Description

Tubenentleerer

The invention relates to a tube emptier according to the preamble of

Claim 1.

Tube emptiers, also known as tube presses, tube squeegees or tube release devices, facilitate the expression of tubes and at the same time reduce waste.

For example, US Pat. No. 3,586,213 describes a tube emptying device which consists essentially of two folding stirrups and two rollers. The two rollers are arranged one above the other and form a gap between them. For easy insertion of the tube between the two rollers, the tube emptier has a folding mechanism. By rotating the upper rollers, the tube is forced through the gap and the material in the tube is squeezed out of the tube.

Although in the US-document the two axes of rotation of the rolls are aligned one above the other during the emptying process, the axis of rotation of the folding mechanism is horizontally spaced from the two axes of rotation of the rolls.

This has the disadvantage that during the emptying of the tube, due to the horizontal spacing of the axis of rotation of the folding mechanism and the resultant torque force, the two rollers are pressed again. The user of the tube emptier must therefore next to the

Rotary movement of the rollers, still exert a holding force on the brackets of the rollers, so that the rollers do not move apart again.

Object of the present invention is now, a tube emptying

provide with which the user with simple means and less Holding force can empty a tube and at the same time a clean

Squeezing process of the tube is achieved.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

An essential feature of the invention is that in the working position of the tube emptying the axis of rotation and the two axes of the rollers are approximately aligned on a common arrangement axis.

Under the approximate arrangement, the present invention understands that the axes are in the region of the array axis. It is therefore

Deviations possible.

In particular, the forces are neutralized by the approximately aligned arrangement on a common axis, since no moment is generated by any of the axis. During the emptying of the tube therefore no longer the upper and lower part must be compressed, as was necessary in the prior art. It rather creates a

Self-locking force which presses the upper part on the lower part.

Furthermore, the embodiment of the invention avoids additional

Devices which are necessary during the emptying process to compress the two shells. For example, the prior art provides a locking mechanism which holds the two parts together (upper and lower part). This is just avoided in the embodiment according to the invention.

In a first preferred embodiment, a first roller is rotatably arranged about a first axis on the upper part and a further roller rotatable about a second axis on the lower part. Both parts (upper and

Lower part) are connected to each other via a rotatable hinge connection. The upper roller is connected to a rotary handle, which allows easy rotation of the upper roller relative to the lower roller.

The shape of the upper and lower part is chosen so that it can be easily held by the two hands of the user. The two parts can either have a closed surface or be partially broken.

The tube emptying device according to the invention can be present in numerous widths, the insertion opening and the width of the rollers being decisive for the respective tube width.

In the folded state of Tubenentleerers there is a nearly closed housing shape, wherein in the roll near area a

Insertion and in the area of the dividing ends an export opening exists.

By foldable (upper and lower) parts of the invention

Tube emptier designed as a kind of pliers, wherein between the rollers, the tube is passed and is crushed by the reduced distance between the two rollers, located in the interior of the tube means from the tube.

A significant advantage of the present embodiment is now that the Tubententleerer is easy to handle, since the user introduces the tube through a designated insertion between two rollers and performs a lateral handle a rotary movement in a clockwise direction. The insertion of the tube takes place in the tube emptying device according to the invention in the longitudinal direction.

In the closed state of the tube emptying are then the common axis of rotation of the upper and lower parts, and the axes of the upper and lower rollers in alignment. By inserting the tube in the front insertion slot, the force of the rollers is evenly distributed to the tube. In addition, the user must hold the housing without permanent handshake.

In a further preferred embodiment, the tube emptier according to the invention has a slotted guide, which consists of at least one

Guide surface and at least one guide groove is made. By the

Slotted guide, the two axes of the rollers are brought in the closed state of the Tubaentleerers in alignment.

With the slotted guide is also achieved that the gap between the two rollers in the open state of the tube emptying significantly increased. Furthermore, with the slotted guide a

Biasing force can be applied via the rollers to the clamped tube.

This was not known from the prior art, since here the axis of rotation of the upper and lower parts was always arranged outside the two roll axes. Due to the horizontal distance of the axis of rotation it came to a

Moment load on the upper or lower parts, which the user had to counteract during the Auspressvorgang the tube.

In a first preferred embodiment, the entire

Tube emptier made of a plastic. However, other materials, e.g. Fiber-reinforced plastics, steel or aluminum possible.

Individual components of the tube emptier, such as the rollers or the rotary handle, can also be made of a different material. For example, the roller may be made of aluminum or steel or a glass fiber reinforced material.

It is crucial in the invention that the upper parts and lower parts are designed in such a way that they already have a function or a design How it works For example, the consumer immediately recognizes that the tube can only be inserted into the frontal insertion opening.

In a further preferred embodiment, the tube emptier in addition to the slotted guide on a projection, a detent on or a similar holding means, whereby the tube emptier remains open in the open state. This means that the upper part and the lower part are held apart from each other.

What matters is that the three axes, i. the common axis of rotation of the upper and lower parts, and the upper axis of the upper roller, and the lower axis of the lower roller are arranged approximately in alignment. The common axis is also referred to below as the arrangement axis.

In a preferred embodiment, the arrangement axis is slightly inclined with respect to the vertical axis. For example, the arrangement axis is inclined forwards in the direction of the insertion opening.

Due to the slightly forwardly inclined arrangement, there is the advantage that the upper and lower parts of the tube emptying be intentionally compressed during the rotational movement of the rotary handle, as is drawn together by the feed operation of the two rotating rollers of the tube emptier due to the angular position of the axes. Find one now

Rotary movement of the rotary handle against the feed direction instead, so there is a force that can jump up the top, since the arrangement axis is arranged eccentrically.

In addition and in addition helps at least one slotted guide, which is arranged in the region of the inner surfaces between the upper and the lower part. The link guide preferably consists of a guide surface and a guide groove and causes the three axes in the closed state continue to be in the alignment axis and prevents that during the emptying of the tube, the top and / or bottom part pops up.

In addition, the semi-circular slide guide allows protection for the axis of rotation of the upper and lower parts, since the slide guide absorbs the resulting forces due to their guide surface over the entire surface. The decisive factor here is that the guide surface bears against a lower surface of the guide groove and thus over the entire surface there is a force transmission to the respective upper and lower parts.

In a further preferred embodiment, the upper part and lower part is made of a non-transparent plastic. Of course, the invention claimed all surfaces, it being possible, for example, that either the upper part and / or the lower part is made of a transparent plastic, so that the user can always see where the tube is and what during the tube emptying process in

Interior of the upper and lower part takes place.

In a further preferred embodiment, the rollers in the closed state of the tube emptying not a distance equal to zero, but a distance of minus 3/10, so that a bias voltage between the rollers. As a result, an effective tube squeezing operation is achieved in particular.

The biasing effect is further enhanced by the use of (plasticized) plastic rollers, which bulge out convexly as the tube passes through, effectively treating the material of the tube.

The subject of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with each other. All information and features disclosed in the documents, including the abstract, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are novel individually or in combination with respect to the prior art.

FIG. 1 shows a perspective view of the tube emptying machine 1 according to the invention. The tube emptying device 1 essentially consists of an upper part 2 and a lower part 3.

The upper part 2 and the lower part 3 are preferably via a rotatable

Connected together. The connection may for example consist of a round projection and a round recess. For example, the round projection on the inner surface of the upper part 2 and the round recess on the outer surface of the lower part 3 may be arranged. But there are also other rotatable connections between the upper and lower parts possible.

On a side surface of the tube emptying 1 is a rotary handle 4 which is rotatably supported in both directions. The rotary handle 4 is preferably connected to the upper roller 6.

According to FIG. 1, the front-side insertion opening 8 is also shown, which serves to insert a tube to be squeezed out. In the region of the insertion opening 8, the upper roller 6, and the lower roller 5 is arranged. The insertion of the tube to be squeezed takes place in the direction of arrow 7 in the insertion opening eighth

FIG. 2 shows a plan view of the tube emptying machine 1 according to the invention, wherein the rotary handle 4 is located on a side surface. Further, Figure 2 shows that the upper part 2 is slightly shorter than the lower part 3 is formed, which allows easy intervention and thus easy opening of the upper part 2. 3 is located on the lower part 3, a slot 13, in which the axis 21, or the drive shaft 11 of the

Turning handle 4 moves.

Furthermore, it is apparent from FIG. 3 that the lower roller 5 has a recess 16 and the upper roller 6 has a recess 15. In the recess 5 of the rotary handle 4 can be inserted. The recess 16 is used for rotational support against two (bearing) pins 9 a, 9 b in the region of the inside of the lower part of the third

Preferably, the rotary handle 4 has a drive axle 11 with a profiling 12, which cooperates positively with the recess 15 of the upper axis 6. By means of the profiling 12 and the profiled recess 15 is achieved that during a rotational movement of the rotary handle 4 is a

Power transmission takes place on the axis 6.

With reference to FIG. 3 it can also be seen that the upper part 2 at a

Side surface has a recess 10. The lateral recess 10 on the upper part 2 serves primarily to ensure that the rotary handle its drive axle 11 is first inserted through the slot 13 and then through the recess 10 therethrough. As a result, in particular a storage of the upper roller 6 is achieved.

The upper roller 6 is shown in FIG. 3 on the opposite side with a bearing pin 14 in connection. The bearing pin 14 is designed such that a rotation relative to the upper part 2 is possible. Thus, the recess 15 of the upper roller 2 preferably has a profiling only in the region close to the rotary handle, which profile cooperates with the profiling 12 of the drive axle. In the region of the journal 14, no profiling is arranged, so that a free rotation relative to the upper part 2 can take place here. With the Fig. 4, 5, 6 and 7, the individual components of the tube emptying system 1 according to the invention are shown once again in an exploded view

With the Fig. 4 it is shown that the lower part 3 has an insertion opening 8, in which the tube to be emptied is inserted. The insertion opening 8 preferably has an oval shape and is bounded by a peripheral edge. It is crucial that the insertion opening 8 is present as a whole in the region of the lower part 3. Due to the undivided shape, the insertion opening 8 is formed very stable and provides the tube during insertion between the two rollers 5, 6 sufficient support.

In addition, the user can immediately because of the size of the

Insertion opening 8 determine which tube size with the

Tube emptier 1 according to the invention can be processed.

5, it is shown that the lower roller 5 has a recess 16 which cooperates in the lower part with a pin 9a. The lower roller 5 is made rotatable and is connected to both the pin 9a, as well as with the pin 9b on the opposite side.

The lower part 3 has a guide surface 17, which preferably

is executed semicircular. The guide surface 17 protrudes beyond the inside of the lower part 3 and preferably cooperates with a guide groove 18 of the upper part 2.

The upper part 2 has in the lateral region on a projection 22 which holds the upper part 2 relative to the lower part 3 in the open position in the open state of the tube emptying 1. The projection 22 can be any

have geometric shape, but it is preferably formed according to the figure 5 as a round knob. With the figure 6, the lower part 3 and the lower roller 5 is shown again. The underside of the lower part 3 is in this case formed so that it is easily accessible by the hand of the user.

From the figure 7 shows that on the opposite side of the pin 9a, a further pin 9b is arranged for rotatably supporting the lower roller 5 with the recess 16.

With the figure 8 is a schematic front view and various

Sections of the tube emptying 1 according to the invention shown. The various sections are explained in more detail in the following figures 9-11.

FIG. 9 shows the section AA in detail. The upper roller 6 is arranged in the region of the upper part 2 and the lower roller 5 in the region of the lower part 3. Both rollers 5, 6 engage in the closed state of the tube emptying device 1. As a result, an effective emptying of the tube is achieved when passing the tube between the two rollers 5, 6.

During a rotational movement of the upper roller 6, a power transmission to the lower roller 5 takes place due to the toothed engagement of the two rollers 5, 6. As a result of the freely rotating mounting of the lower roller 5, the tube is thus guided through the toothed engagement of the two rollers 5, 6.

Due to the strong diameter reduction in the area of the rollers 5, 6 and the elastic deformability of the tube body, it comes to a

Squeezing the tube, causing the contents (for example toothpaste, mustard, cream, mayo etc). is pressed in the direction of the tube opening. As a result, a nearly empty or almost residue-free tube body is achieved.

From the figure 9 also shows that the lower part 3 also has a rotatable mounting 9, which with the recess 16 of the roller fifth

interacts. In the closed state of the tube emptying machine 1, the upper part 2 rests on the lower part 3, wherein an aligned alignment of the rollers 5 and 6 is present.

With the figure 10, the arrangement of the section B-B is shown, which is explained in more detail with the figure 11. It can be seen from FIG. 11 that, in the closed state, the axes of rotation 19 of the upper and lower parts 2, 3, the axis 21 of the upper roller 6 and the axis 20 of the lower roller 5 are arranged parallel to one another.

Furthermore, it can be seen from FIG. 11 that the guide surface 17 is in the

closed state of the tube emptying 1 is located within the guide groove 18. As a result, a good power transmission between the upper and lower parts 2, 3 is achieved.

FIG. 12 shows that both the axis 19 and the axes 20 and 21 are in alignment.

13 shows an enlarged view of the section CC according to the figure 8. In the closed state of the tube emptying 1 are the axis 20 of the lower roller 5, and the axis 21 of the upper roller 6, and the axis of rotation 19 on a common axis 23, which is referred to as arrangement axis 23. The arrangement axis 23 has an angle 25 with respect to the actual vertical axis 24.

The arrangement axis 23 can be arranged parallel to the vertical axis 24 or also at an inclined angle 25 to the vertical axis 24.

In a preferred embodiment, the angle 25 between the axis 24 and 23 is inclined by about 10 degrees. This means that the axis 23 has inclined in the direction of the insertion opening 8 with the angle 25.

The alignment of the three axes 19, 21 and 20 has the advantage that the occurring (moment) forces, which during the Emptying the tube arise, greatly reduced. In addition, the forces occurring are counteracted by the inclined arrangement axis 23, so that the upper part 2 remains on the lower part 2. On top of the upper part 2 is avoided.

Furthermore, the inclination of the arrangement axis 23 with an angle 25 has the advantage that during a rotary movement of the handle 4 a retraction movement of the tube in the direction of the rollers 5, 6 is achieved.

FIG. 3 further shows that the arrangement axis 23 is inclined in such a way that the upper roller 6 is arranged horizontally closer to the insertion opening 8 than the lower roller 5. The smallest horizontal distance to the insertion opening 8, however, has the axis of rotation 19.

Thus, the angle 25, which is preferably inclined by 10 degrees to the front, that in a rotational movement of the (rotary) handle 4 an additional

Contraction of the two rollers 5, 6 is achieved.

In an opposite rotation of the rotary handle 4, that means counterclockwise, immediately jumps to the upper part 2.

According to FIG. 13, the axes 19, 20 and 21 have a spacing 26 and 27. The distance 26 results between the midpoints of the axis 20 (lower roller 5) and the center of the axis 21 (upper roller 6).

The distance 27 results between the center of the axis 21 (upper roller 6) and the center of the axis 19 (axis of rotation of 2 and 3).

Thus, in a preferred embodiment, the axle spacing 26 has an undersize, ie, less than 0, whereby the axles 20 and 21 are compressed more than intended. Furthermore, it can be seen from the figure 13 that in an opening operation of the upper part 2 relative to the lower part 3 of the pivot point of the axis 19 is guided in the direction of the vertical axis 24.

FIG. 14 shows the positions of the sections A-A and C-C with respect to the tube emptying device 1 according to the invention.

With the figure 15, the tube emptier 1 in sections A-A in his

Open position shown. The upper part 2 is folded in the direction of arrow 28 upwards.

The upper roller 6, which is connected to the upper part 2, is spaced from the lower roller 5. Between the rollers 5, 6 there is an enlarged distance 29, so that a tube is easy to insert. In the open state of the tube emptying device 1 so that the distance 29 is greater than the distance 26th

According to the figure 16 the section C-C is shown. The upper part 2 has the guide groove 18, in which the guide surface 17 of the lower part 3 is arranged displaceably.

The axis 20 of the lower roller 5 and the axis of rotation 19 of the upper and

Bottom parts 2, 3 are in the open state of the tube emptying 1 as before aligned on the arrangement axis 23. The arrangement axis 23 is inclined relative to the vertical axis 24 at an angle 25.

FIGS. 17 to 19 show the tube emptier 1 in the closed state. From the figure 18 it follows that in the closed state, the two

Rollers 5, 6 are in toothed engagement.

According to the figure 19, which shows the section C-C, it follows that the
