Description

The invention relates to dispensing containers, especially on containers with an improved shape so that they can be used by adults and children.

Most dispensing containers currently in use serve use by adults. Small children have a lot smaller hand sizes and it is therefore difficult for them to find one Treat product from containers and effectively dispense that are designed for use by adults. Vice versa it would be difficult for an adult to have a dispenser to use, which is specific for use by small children was designed.

Another related problem with common ones Containers are used for dispensing products be designed by adults, d. that is, the size of the for Squeezing the product out of the container required force is adapted to the strength of the adult's hand. Children and older people are weaker than most adults and have lower forces to dispense products. Therefore, it is desirable to have a container that requires a low dispensing force so that the container of is preferred to those who have great strength her hands are lacking.

With a normal packaging for toiletries The products are often stored in an upright position packed, d. i.e., in the closed end of the container is under its open end, just like that Container is positioned when it is filled with the product that he should include in it. While such products often The product will be stored in an upright position often abge from the container in an inverted position give. Containers in particular have a certain delay on, d. that is, an amount of product due to contact with the Container walls are not delivered appropriately. The The size of the delay is increased for containers where the product is stored in one position and in the opposite set alignment is used. This problem continues  reinforced in the case of viscous products such as B. shampooing average.

Another problem with conventional containers is in that they can slip out of your hands, especially when the hands are wet. This poses a particular problem for Containers containing toiletries, typically used in the bathroom by young children, such as B. Shampoos and body cleaning products.

It is therefore an object of the invention to To create a dispenser that is designed so that it comfortably in the hands of both toddlers and adults it fits.

It is another task of the present inventor to provide a container that requires little force, to dispense products from it so that it prefers from those who do not have great strength of their hands.

Another object of the invention is containers with design features that create the container on it prevent users from slipping, especially when their hands are wet.

It is another object of the invention to provide one To create containers that are stable in the reverse position can be stored in this way to retain the To minimize the content of the container, in particular especially when it comes to the storage of viscous liquid products ten is used.

Yet another object of the invention is there rin to create a container for use by Kin which is ergonomically effective for both adults and adults, while it surfaces has, which facilitate the labeling of the container.

The invention solves these problems by Features contained claim 1.

The term "upright" used herein Position "means the closed end of the container is under the open end of the container, just like the container positioned when it is filled with a product that should be included in it. Conversely, the term means "Inverted position" that the closed end of the container is positioned over the open end. In a similar way the designation "lateral position" means that the Container has an alignment between the upright and reverse position. This position description will used only for convenience by the Alignment of the container is described and it is not intends the position of the container during storage and delivery of products contained therein to involve. As described below, the various embodiments of the containers of the invention either in an upright or an upside down Position described.

The basic form of the invention is shown by a container in an upright position in FIGS. 1A, 1B and 1C, generally designated 6 . The container 6 has an open end 1 and a closed end 2 . The closed end 2 of the container 6 preferably has a side 21 which enables the container 6 to stand when it is set down on a flat surface in an upright position. The open end 1 of the container 6 has a neck 3 which forms an opening 20 in the container. The neck 3 is provided with a neck finish 4 , which serves to cooperate with a closure, not shown, for the container. The neck finish in Figures 1A and 1B is threaded, although any other equipment known in the art can be used for the containers of the invention. For example, suitable equipment includes, but is not limited to, a latching end, a snap-in and rotating equipment, or an aligned threaded end, such as, e.g. B. in "The Wiley Encyclopedia of Packaging Technology, 172-85 (1986) (hereinafter referred to as" Wiley ").

The open end 1 of the container 6 further comprises a shoulder 5 which connects the neck 3 to a main part 22 of the container. The main part 22 of the container contains an upper main part 7 in the vicinity of the open end 1 , which is preferably cylindrical in cross section. The upper main portion 7 of the container 6 preferably has a circumference that, measured perpendicular to the longitudinal axis 23 of the container, is from about 119.38 mm to 152.4 mm (4.7 inches to about 6.0 inches), more preferably from about 127.0 mm to 144.78 mm (5.0 inches to about 5.7 inches), and most preferably from about 132.08 mm to about 144.78 mm (5.2 inches to about 5.7 inches). The upper body 7 preferably has a substantially constant circumference for a length of at least about 5.08 mm (0.2 inches) along a longitudinal axis 23 of the container 6 .

As shown in FIG. 1A, the upper main part 7 merges into a central main part 8 , which is arranged below and near the upper main part 7 along the longitudinal axis 23 . In the transition region from the upper main part 7 to the central main part 8 , the circumference of the container 6 increases continuously and begins to take on a generally oval or elliptical cross-sectional shape. Further down along the longitudinal axis of the container 6 , the circumference of the container increases up to a region 9 of maximum circumference, after which the circumference of the container 6 preferably decreases continuously. The area 9 of maximum circumference marks the transition from the central main part 8 to a lower main part 10 of the container 6 in the vicinity of its closed end 2 .

While the longitudinal length of the upper body 7 , middle body 8 and lower body 10 may vary depending on the desired use of the container 6 , the ratio of the lengths of the middle body to the upper body is preferably about 1.2: 1 to about 6: 1, and more preferably ranges between about 1.75: 1 and about 5: 1. The ratio of the lower body to the upper body preferably ranges from about 1: 1 to about 3: 1, and more preferably from about 1.2: 1 to about 2.5: 1.

The change in the cross-sectional shape and the circumference of the container 6 along the longitudinally extending length is shown in FIGS. 2A to 2F. Each of these figures shows the approximate cross-sectional shapes along the section lines AA to FF in FIG. 1C. It has been unexpectedly found that changing the circumference of the container along the longitudinal axis of the upper main part 7 offers the possibility that the same container, which is ergonomically advantageous for use by small children, can be held comfortably and can also be used by larger children and adults .

As shown in Fig 1A and 1B show., The main part 22 of the container 6 includes a front 11, a back 12, a first side 13 and a second page 14. The front 11 of the container has a first recess 15 and the rear 12 of the container has a second recess 16 . The recesses are located in the vicinity of the closed end 2 , the first side 13 and the second side 14 of the container 6 . The first recess 15 and the second recess 16 form a first wall 17 and a second wall 18 on the front and rear of the container, respectively. Each of the recesses has a depth 19 , as shown in FIG. 1B. The depth of the recess 15 is, for example, the distance perpendicular to the longitudinal axis from a projection line 21 ', projected from the closed end 2 of the container 6 onto the first wall 17 of the container. As FIG. 13 shows, the recesses 15 , 16 have a depth 19 which is sufficient for the container 6 to be separated from a first holder 71 , which is positioned tangentially into the recess 15 on the front side 11 of the container 6 , and through a second holder 72 , which is positioned in the recess 16 on the rear side 12 of the container 6 , can be held when the container is arranged in an inverted position; the holders 71 , 72 actually do not touch the walls 17 , 18 of the container. It has surprisingly been found that the depth 19 of these recesses 15 , 16 is effective in creating an anti-slip property of the container when the container is held in either an inverted or lateral orientation, particularly when the container is wet, such as this the case could be if it is used to receive and dispense cleaning toiletries, such as. B. Body cleansers and shampoos that are used in the shower or bathroom.

The depth of the recess can be of any desired thickness and can e.g. B. depend on the desired final use of the container and the content therein. The depth of the recess is preferably different at different locations on the container and it is more preferred to provide the greatest depth in the vicinity of the closed end 2 of the container and the depth gradually in the longitudinal direction to the open end 2 and in the vicinity of the first side 13 and the second side 14 to decrease. The depth of the recesses 15 , 16 preferably ranges from approximately 2.0 mm to approximately 3.4 mm and more preferably from approximately 2.5 mm to approximately 2.9 mm. While such depths are preferred because they provide a container with effective anti-slip properties, it will be appreciated that other depths of the recesses 15 , 16 can be created to meet a particular requirement and which still falls within the scope of the present invention.

In a preferred embodiment, the recesses 15 , 16 are not near the open end of the container and therefore form a U-shaped outer frame for the walls. The lack of a recess near the open end 1 allows the users of the container to be free with their hands over the substantially entire length of the first and second walls 17 , 18 from the lower end of the walls in the immediate vicinity of the closed end 2 of the container can slide to the open end 1 of the container to find that part of the container that has a circumference that best matches the hand size of the user.

It is believed that the above dimensions solutions and design features of the container of the invention allow the containers of the invention to be easily gripped and both adults and toddlers in one ergonomically preferred way can be handled. How will be explained below, these dimensions and Merk bear paint the understandable preference of consumers regarding the manageability of the containers of the invention known containers bill.

As shown in FIGS. 1A and 1B, the walls 17 and 18 are recessed relative to the sides 13 , 14 and the closed end 2 of the container. Although the size, shape and geometry of the walls may vary depending on the desired end use of the container, it is preferred that the first wall 17 and the second wall 18 be identical in size, shape and geometry. The walls have a major dimension in the direction from the open end 1 to the closed end 2 of the container, ie in a direction generally parallel to the longitudinal axis 23 of the container, and a smaller dimension in the direction from the first side 13 to that second side 14 of the container, ie generally normal to the longitudinal axis 23 . The length of the wall is defined as the distance between the point of the first recess 15 which is closest to the bottom of the container 24 , ie a point 30 , to an upper end 29 of the upper main part 7 of the container.

The walls 17 , 18 have surfaces 27 and 28 which are either substantially flat or curved. If the wall surfaces are curved, it is preferred that the curvature extends in only one dimension and is substantially straight in the other dimension. For example, the container of the invention shown in FIGS. 1A and 1B has walls 17 , 18 which are curved in their smaller dimension, but run in a straight line ver in their main dimension. It is more preferred if the walls are substantially straight in their major dimension over a distance that is at least about 50% of their longitudinal length on the longitudinal length of the wall, and, even more preferably, at least about a length 65% of their longitudinal length is based. It has been found that this wall geometry is particularly advantageous for labeling or decorating the container on its wall sections either by printing or by adhering a label provided with adhesive on the back to the container. In the case of printing, the absence of a curvature in two dimensions over a substantial part of the wall enables a pressure roller to make firm contact with this part of the wall. Similarly, in the case of a two-dimensional curvature over a substantial portion of the wall, an adhesive label can be adhered to the wall without curling or wrinkling the label.

Fig. 3A and 3B show alternative embodiments of the container of the invention, said container optionally erha bene, lateral projections 25 or recesses 26 have, at their sides to means for improving the feel of the fingers to enable a user to the container. Optionally, the containers of the invention can have a combination of both protrusions and depressions. Although FIGS. 3A and 3B only lateral projections and arc-shaped recesses show it is understandable Lich skilled in the art that the container of the present invention, before cracks, pits and / or other grip-improving means such. B. rubber or polymeric sections can have, which are molded or glued to the container and can have any shape, size and quantity to improve the grip of the user of the container.

FIG. 4 shows an alternative embodiment of the container in FIGS. 1A and 1B, the volume content of the container in FIG. 4 being approximately half the volume content of the container in FIGS. 1A and 1B.

In a further embodiment of the present invention in FIGS. 5A and 5B, a closure 39 is placed on the container 6 of the present invention to enclose and dispense the products contained therein. One skilled in the art will immediately recognize that this type of closure is suitable for use in the present invention and depends on various factors such as: B. the shape of the product in the container, the desired shape in which the product is to be dispensed, and the degree of ease of handling to be offered to the consumer.

Any closures known in the art can be used with the containers of the present invention including, but not limited to, which are described in Wiley.

For containers for storing and dispensing rivers liquid would be the simplest form of closure a common one-piece construction cap that is made by The container must be removed to get the product out of it deliver; however, the use of a closure preferred, which does not have to be removed from the container in order to to deliver the product out of this.

An example of a container 6 provided with a closure 39 for dispensing liquid products is illustrated in Figures 5A, 5B and 5C, in which the container of Figures 1A and 1B is provided with a commercially available hinge closure. Other suitable closures include those known in the art that include, but are not limited to, the following features: 1) those that include a lid and body, the lid being completely removable from the body of the buckle; 2) those with a lid slidably connected to the main part of the closure; 3) those that do not have a lid, such as B. the push-pull type and the tilt lock type of clos sen, as z. B. are described by Wiley.

The closure 39 comprises a main part 31 and a lid 32 which is connected to the main part by a hinge 33 in a kidney-like manner. The main part 31 contains an opening, not shown, through which the product can be dispensed. The lid 32 has a pin, not shown, on its underside which is dimensioned such that it can engage tightly in the opening of the main part 31 . When the lid 32 is in its closed position, the pin contacts the main part 31 so that the container is sealed and the contents are thus prevented from being dispensed. The main part 31 can optionally have a recess 34 so that the closure can be easily opened by positioning a finger in the recess 34 under a part 35 of the cover 32 and then exerting a force on the underside of the cover 32 .

The closure 39 has a base 36 in the vicinity of the upper main part of the container and an upper side 37 on the side remote from the base 36 . The closure 39 has a substantially uniform, circular circumference from its base 36 to its upper end 37 which is substantially equal to the circumference of the upper body of the container.

Another new feature of the present invention is shown in FIGS . 5A to 5C. The closure 39 preferably has a head surface 38 which enables the container to be stored in an inverted position. When the contents of the container are exhausted, storing the container in the inverted position allows the remaining contents of the container to accumulate at the open end of the container instead of its closed end, so that delivery of substantially all of the contents of the container is possible, and that Problem of retaining more viscous content is effectively eliminated. Preferably, both the closed end of the container and the upper end of the closure have surfaces which enable storage of the container in either an upright or inverted position.

Another embodiment of the container of the prior invention is shown in an upright and inverted position in FIGS. 6A and 6B, respectively. The closure 40 has a base 41 in the vicinity of the upper main part of the container and an upper side 42 on the side facing away from the base. The base 41 has a substantially circular circumference which is substantially equal to the circumference of the upper main part 7 of the container. The closure 40 is tapered such that the circumference of the closure increases from the base 41 to the top 42 of the closure. The extent of the taper can vary depending on the desired end use of the container and the desired aesthetic effect. The closure 40 has a head surface 43 which allows the container to be stored in an inverted position. The larger circumference at the top of the tapered closure gives the container additional stability when stored in an inverted position.

In a further preferred embodiment, the closure used in the containers of the invention may have a valve as shown in Fig. 15A. Examples of suitable valves for use with the containers of the invention are found, without limitation, in U.S. Patents 5,439,143, 4,749,108 and 4,846,810, all of which are incorporated by reference. Such valves are generally designed to open at pressures above a certain threshold pressure, thereby releasing the product from the container, and to close at pressures below the threshold pressure, thereby interrupting the dispensing of the product from the container. The minimum value of the threshold pressure of the valve is determined by the requirement that the valve retain the contents of the container when the container contents exert the highest pressure, ie when the container is filled. The maximum pressure of the container contents in turn depends on the density of the contents and the geometry of the container. In practice, the lowest threshold pressure is slightly higher than the maximum pressure to allow for adaptation to the small pressure changes that can occur in the container when it is subjected to handling without the desire to dispense the contents. The maximum value of the threshold pressure is determined by the requirement that the valve open when the container is squeezed or compressed by the user. In containers of the invention, the valves must be activated not only by adults, but also by children and / or older people who have relatively lower forces in their hands.

For containers made from elastic materials are applied, the application of a squeezing force on the Outside of the container a pressure inside the container that exceeds the threshold pressure, causing the Product can be released from the container. A sub refraction or a sufficient reduction in the squeezing force reduces the pressure inside the tank under the smolder oil pressure, causing the release of the product from the container ter can be interrupted. This property is special important in applications where the container is often in the reverse position is used.

FIG. 15A and 15B show a container of the invention with a closure 85, having a lid 84 and a valve 80. The cover 84 is connected to an extension part 86 by a hinge 83 . The cover 84 contains a stopper 82 on its underside, which interacts with a projecting opening collar 81 of the closure 85 . In use and in a position ready for product delivery, the lid 84 is in the retracted position shown in FIG. 15A. During storage and during transportation, the lid 84 is in the closed position shown in FIG. 15B. In the closed position, the plug 82 engages on the underside of the cover 84 in the projecting opening collar 81 , thereby preventing the valve 80 from switching over and releasing the product. The closure 85 has a circumference on its underside 88 near the upper body of the container which is substantially equal to the circumference of the upper body of the container. The closure 85 is tapered, the circumference on its top 87 being larger than on its bottom 88 . The larger circumference at the top 87 of the closure 85 provides an additional stability of the container when stored in the reverse position.

There can be valves in the closures by means of known methods, including, but not limited to, the mounting of the valve in the Closure by mechanical means, such as. B. by the Use a retaining ring that is in its position in the Container engages with snap action. Such one Closure is described in US Pat. No. 5,377,877 to which here in full reference is made. Optionally, the valve and the closure be uniformly shaped, such as. B. by Multiple injection molding or simultaneous injection molding of different materials for the closure and that Valve. Methods for simultaneous injection molding are e.g. B. in U.S. Patent 5,523,045 and in Modern Plastics Encyclopedia, McGraw- Hill, New York, 1990, described in full here Scope is referred to.

Figure 6B shows the container of Figure 6A in an inverted position. It is clear that the container is generally in the form of an exclamation mark in the reverse position. The container dimensions are such that toddlers can conveniently and conveniently grip the container near its upper body 7 , while larger children and adults can comfortably grip the container in its central body 8 or on its lower body 10 . The container 6 is preferably of a size and shape which allows an adult with average size hands to hold the container at its widest point 9 by holding the back of the container in the palm of the hand such that thumb and fingers touch the sides of the container and can at least partially grasp the front of the container.

In an alternative embodiment, the containers of the present invention may include a closure which is used to dispense liquid in the form of a spray or aerosol. An example of an aerosol dispensing container of the invention is shown in Figure 7, in which the container of Figures 1A and 1B is provided with a commercially available closure 50 which contains an aerosol pump. The closure has a knurled collar 51 , which facilitates attachment to the container and gripping the container at least in the area of the knurled collar. The product contained therein is discharged from the container through an opening 53 by pressing down the pump piston 52 .

Other spray devices known in the art can be used with the containers of the invention including but not limited to squeeze spray container by squeezing the container be operated or by a spray piston as in The Wiley Encyclopedia of Packaging Technology, John Wiley and Sons, New York, 1986.

In an alternative embodiment, pro products such. B. liquid, surface-active products from the containers 6 , such as. B. foams, by appropriate supply of air to the liquid when it is dispensed, who dispensed the. For example, U.S. Patents 5,271,530; 5,570,819; 4,022,351; 5,037,006; 5,364,031 and 5,462,208 foam dispensing nozzles and pumps, all of which are incorporated herein by reference. The foam is released in particular from containers containing such nozzles and pumps either by squeezing the container or by actuating a pump.

Another embodiment is directed to a container with a neck end design, which is used to dispense powdery solids such. B. talcum powder is used, as shown in FIGS. 8, 9, 10A, 10B and 10C. The final neck 60 of the container includes grooves 61 which communicate with the empty volume of the container and flat sides 62 . A closure 63 interacts with the neck finish 60 with a snap action. Closure 63 includes one or more holes 64, preferably in a pattern that matches the pattern of channels 61 in neck finish 60 . The closure can rotate freely at least part of a turn when it is in cooperative contact with the neck finish. The open position that enables dispensing from the container is shown in FIG. 10B, with the holes 64 in the closure 63 aligned with the channels 61 in the neck finish 60 . Similarly, FIG. 10C shows the closed position of the closure, in which the closure is rotated by 30 ° with respect to the position shown in FIG. 10B.

The containers of the invention can be any mate rial included, which can be brought into the desired shape can and the inert to the materials contained therein is. Preferred materials include any elastic polymeric materials commonly used in manufacturing of containers can be used, including, but not limited to, polyethylene, polypropylene, polyvinyl chloride-based resins, polyethylene terephthalate or copoly merisate or mixtures thereof. "Copolymers" means herein any polymer with two or more monomeric compos nenten. There can be different types of polyethylene including low density polyethylene, polyethylene medium compression, high density polyethylene, or it are copolymers or mixtures thereof in many cases Toiletries compatible and preferred materia lien for the container of the invention. Low density Polyethylene gives a bottle that is relatively easy to handle is squeezing while high density polyethylene bottles results that are relatively stiff. With liquid produc ten, which are released by squeezing the container a 50:50 mixture of low and high compression tetem preferred polyethylene. For powders where the desired  Dispensing is done by shaking the container stiffer container made of high density polyethylene preferred. The thickness of the outer walls, i.e. H. the walls, the first page, the second side and the like can be any one desired te thickness, different for the same container and can be of the desired end use of the container and the content stored in it. Preferential the thickness of the walls is from about 0.254 mm to about 1.27 mm (10 mils to about 50 mils), and preferably from about 0.762 mm to about 1.016 mm (30 mils to about 40 mils). While such thicknesses are preferred because they are easily too lead an elastic container, it is understandable that Other wall thicknesses can be made to be special Requirement to be met, but in the scope of the existing ing invention fall.

1) Dispensing Force Test: The one for dispensing the content force or "dispensing force" of a container using a "Uniforce Experimenters Kit" (version with parallel entry / exit openings), manufactured by Force Imaging Technologies, which measured a thin (0.003 mm), flexible sensor strips on different surfaces placed on the test sample with little or no effect and software (Uniform Sensor System, version 5) as well as hardware that provides an interface for the Sensor with a personal computer for data acquisition, having.

A sensor strip with the appropriate force range (usually 0-4.54 kg (0-10 lbs.)) Is placed on one of the walls of the sample container with the sensor attached to the location where a user's thumb will typically hold the container during a normal one Dispensing the product from the container would touch, as Fig. 14 shows. In an adult's hand, the thumb would normally touch the wall at a location between about 70% to about 80% of the length of the wall, closest to the closed end 2 of the container. The software is set to acquire data for a period of between 1.25-1.75 seconds. The container is held in one hand by a user with the thumb on one side of the container and the other finger on the opposite side of the container. With the thumb on the sensor, the container is held in a vertical position, with the dispensing opening held down over a cup standing on an electronic scale of the model. The containers are then squeezed by hand with sufficient force to open the valve and dispense a standard amount (3-6 g) of the product contained therein. The maximum force required to open the valve and dispense any amount of product is an output signal from the computer program. The magnitude of the force together with the weight of the product delivered is manually tabulated by the person performing the test.

After resetting the scale to zero, the Repeat the above test sequence until the container of all product is completely empty. The one from the testing Person-collected data is then used to make a slide Record grams showing the force required is to the valve as a function of that of the container to open the total amount of product dispensed.

EXAMPLE 1 DELIVERY FORCE MEASUREMENT

To dispense the product from the containers of the present the force required by the invention was as much as the various commercially available containers listed in table 1 shown below, according to that described above Delivery force test measured. Each of the containers in Table 1 was provided with a closure, the one made of silicone existing delivery valve of Seaquist Closures, Mukwonago, Wisconsin.  

Table 1

Container types

In order to eliminate any inconsistencies resulting from products of different viscosities to be dispensed, water was substituted for the packaged and sold contents of all containers. The results of these force measurements are shown in Fig. 11.

It can be seen from Figure 11 that the containers of the present invention require the least force to deliver a product over other containers tested. Accordingly, the containers of the invention are expected to be best suited for dispensing a product by persons who have little hand strength, such as toddlers and older adults.

CONSUMER TESTS

In-house consumer tests were performed on the containers of the invention in Figures 5A, 5B and 5C. Consumers were asked to compare the container of the invention of the invention with a known container shown in Figs. 12A and 12B which is currently used commercially as a container for children's toiletries. The containers were rated in a hundred households by mothers and children aged 6 to 10 years. The containers were rated for ease of handling by asking participants how they judge the container in the following categories:

• 1. very easy to handle for a child
• 2. easy to handle for a child
• 3. neither easy nor difficult to use
• 4. difficult for a child to handle
• 5. very difficult for a child to handle.

The results of this "manageability" assessment are listed in Table 2 below:

Table 2

Manageability of containers

Percentage that the container found to be very light or easy to use

Thus, the information in Table 2 shows that both mothers and children found that the container of the invention is significantly easier to handle than the known container in Figs. 12A and 12B. The dimensions and the structural features of the above-mentioned containers of the invention are believed to enable the containers of the invention to be easily grasped and handled by both adults and young children in an ergonomically preferred manner. These dimensions and properties are believed to reflect the perceived preference of consumers for the manageability of the containers of the invention over known containers.

UNIQUENESS OF THE CONTAINERS OF THE INVENTION

Children were asked to compare the uniqueness of the shape of the container of the invention with the known container in Figures 12A and 12B. Respondents were asked to rate the containers according to the following criteria:

• 1. Extremely new and different
• 2. Very new and different
• 3. Somehow new and different
• 4. Something new and different
• 5. Not at all new and different

The results of this uniqueness assessment are shown below:

Table 3

Uniqueness of the containers

Percentage of children who found the container to be extremely new and different or very new and different

Thus, the children became Erfin containers Noticeably more unique than known containers.

The above description goes without further ado shows that modifications of the invention without departing from the concepts described therein are possible. Such Modifications are included in the following claims unless the wording of the claims expressly something contains other.
