Description

Short description: Drinking device and stack of drinking devices Description
The present invention relates to a drinking device, in particular to a drinking device suitable for drinking hot tea.
Many drinking devices are known for drinking hot drinks, such as hot tea. The present invention relates in particular to single-use cups in which tea can be taken from, for example, a point of sale such as a kiosk to be drunk shortly thereafter. In practice, hot water is supplied to a consumer with a separate tea bag in the cup, and the user can draw tea of the desired strength at a suitable moment by immersing the tea bag in the water at a chosen moment. The user determines the strength of the tea by keeping the tea bag submerged in the water for a shorter or longer period.
Known are transparent or opaque plastic cups, which have the disadvantage that the heat from the tea is simply transferred to a user holding the cup. This is experienced as very annoying, at least if the water is hot enough for brewing tea. It is known thereby to taper the cups so that they can be stacked into each other. It is also known to provide a tapered sleeve in which the plastic cup is placed on sale by the seller, and in which the cup hangs, as it were, when the drinking device thus assembled is held by the sleeve. However, this is cumbersome for the seller. Cups of expanded polystyrene (EPS) foam are also known, wherein the EPS has a heat-insulating function, but which have the disadvantage that the cups are not recyclable. There are also cardboard cups that are laminated with a liquid-tight inner layer. The cardboard is somewhat heat insulating. The cardboard laminate with a liquid-tight inner layer is also difficult or impossible to recycle. Moreover, many materials such as the laminated cardboard and the EPS have an adverse effect on the taste of beverage contained in the cup, which is relatively noticeable particularly in the case of tea because of the fine taste of tea.
The present invention therefore has for its object to provide a drinking device according to the introduction, which solves the abovementioned disadvantages or at least substantially reduces them. This object is achieved according to the invention with a drinking device particularly suitable for drinking tea, comprising a transparent cup made of plastic with a side wall extending over a height h with a circular cross-section, which is provided with a bottom at the bottom and at the top of an at least substantially circular top surface extending at right angles to the side wall, and further comprising a holder in which the cup, at least at least in the assembled state of the drinking device, is received and comprising an over a height h ', which side wall is provided with a bottom and at the top with a top edge, wherein at least for a part of the side wall of the holder it applies that h <h' and of which holder the shape and dimensions, insofar as the holder and the cup overlap each other, at least substantially correspond to that of the cup and wherein the overlap pin g of the cup and the container has a heat insulating effect. The side wall of the holder is a substantially continuous wall which provides a user with an at least at least substantially continuous gripping surface, this to distinguish plastic frames with an ear with which the holder can be held. The container preferably has no protruding parts that would impede the nesting of a number of such drinking devices. The colorless transparent cup, in combination with a holder which extends, at least in part, only over a smaller height than the cup, provides a user with the possibility of visually assessing the strength of the tea while the tea is being brewed and remove a tea bag from the cup at a desired moment (at a desired strength). The holder has the function of obstructing the heat transfer from the contents of the cup to the hand of a user. This is possible, for example, because the holder itself has sufficient heat-insulating properties when the holder connects closely to the cup, or because space is provided between the holder and the cup for providing an insulating effect. The bottom of the container, like its side wall, provides rigidity to the plastic cup, so that the cup can be of thin-walled design and so that the cup can possibly be carried by a consumer at the bottom, or the cup can be carried by the consumer with one or a few fingers. are supported. Where in this document an orientation is stated, this is in relation to a cup with the bottom facing down. Due to the added properties of the holder, fewer or less high demands have to be made on the material of the cup.
This frees up space for other properties and, for example, it is easier to select a material that has no or a minimal taste release from the cup to the consumer during the drinking device.
The bottom of the container is preferably flat in order to form a flat supporting surface or a flat supporting edge. The bottom of the cup is preferably flat, so that its shape matches that of the container. In the assembled state of the drinking device, the bottom of the cup and the holder preferably extend parallel to each other, so that the contents of the holder can be optimally utilized for receiving a beverage contained in the cup. In a preferred embodiment, the bottoms of the cup and the holder are in contact with each other in the assembled state of the drinking device, or they extend at a minimum distance from each other. That is, the mutual distance at the point where the bottoms are closest to each other is a maximum of 3 mm or a maximum of 2 mm.
In a preferred embodiment of the present invention, the cup and the holder are attached to each other. This ensures that the person who takes a drinking device according to the present invention, for example from a stack of such drinking devices, automatically takes the holder with him when gripping a cup. This is particularly important if the side wall of the container nowhere extends to, or at least near, the top edge of the cup. It is thus prevented that the person issuing such containers with drink has to perform additional operations to slide the container and the cup into each other.
It is preferred here that the cup and the holder are attached to each other by means of point bonding. Point bonding provides a sufficient fastening and, on the other hand, limits the amount of glue required for fastening.
In a preferred embodiment of the present invention, the bottom of the cup is directly attached to the bottom of the container. Herewith the adhesive fixation is, at least for the most part, kept out of sight of a user. Moreover, the space between the bottoms of the container on the one hand and the cup on the other is suitable for applying the glue connection. The glue connection can also serve as a spacer between the (bottoms of) the cup and the holder.
Alternatively, or additionally, the holder and the cup are connected to each other by means of a clamp connection. When applying a clamp connection, an adhesive connection can be avoided or supported.
The clamping connection must here be so strong that when a cup is taken from a stack of drinking devices, or when a holder is packed from a stack of inverted drinking devices, the holder or the cup is automatically carried along.
In a preferred embodiment according to the present invention, the top edge of the holder is provided with recesses. That is, the sidewall of the container extends at or in one or more particular locations or regions less far toward the upper edge of the cup than at any other location. The relatively high side wall part of the holder thus provides a good gripping surface for the user, while the relatively low part of the side wall, or the recess, allows a user to increase the strength of the liquid contained in the drinking device, for example tea. see. It is preferred here that two recesses are provided diametrically opposite each other, so that it is possible to look through the cup at the location of the recess. The upper edge can take various forms, for example, have a tilt-like character or have a corrugated character.
It is preferred here that, in the assembled state of the drinking device, the side wall of the container extends partly to or near the upper edge of the cup, and partly extends along the side wall of the cup over a distance of <0.75 h. A good combination of grip and transparency is thus provided.
In an alternative embodiment according to the present invention, it is preferred that the top edge of the container extends in one plane, the height h 'of the side wall of the container being in the range of 0.3 h to 0.8 h . In such an embodiment, a trade-off is always made between a relatively large height h for providing a sufficiently large gripping surface, and a relatively small height for providing a view of a beverage present in the drinking device. The height h 'of the side wall of the container is further preferably at least 0.4 h and / or at most 0.7 h.
To provide a good heat barrier between a hot liquid in the cup and the hand of a user holding the drinking device, it is preferable that between the outside of the side wall of the cup and the inside of the side wall of the container in assembled condition there is minimal play of the drinking device, so that air present between the cup and the holder acts as a heat-insulating layer. The clearance is preferably less than 2 mm, further preferably at least 1 mm or even 0.5 mm.
In order to provide the possibility of stacking a number of drinking devices, it is preferable that the side walls of the cup and the container tap out from top to bottom.
When the container is made of paper or cardboard, the container provides some insulating effect and the paper or cardboard can be printed with a text and / or a design.
If the container is alternatively made of foamed plastic, such as for example EPS or expanded polylactic acid, the container can have a good heat barrier between a hot liquid present in the cup and the hand of a user without the need for an insulating layer of air between the container and the cup. provide.
The upper edge of the cup is turned back or otherwise bent outwards, thus providing a relatively thick and thus pleasant drinking edge for the user.
At least at least if the holder tightly encloses the cup, it is preferred that the holder is made of a material with a thermal conductivity of at most 0.1 W / mK, further preferably at most 0.060 W / mK. Thus, without the effect of an insulating layer of air, the container provides sufficient insulating action to cause the drinking device filled with hot liquid to be grasped by a user without the risk of it burning his hand.
If the holder encloses the cup in such a way that air is carried between the holder and the cup as an insulating layer, it is preferred that the holder is made of a material with a heat conductivity coefficient of at most 0.3 W / mK, further preferably at least maximum 0.2 W / mK. The air with a relatively low heat conductivity coefficient provides, as it were, a second heat insulating layer and thus supports the insulating effect of the container. In other words, the air between the cup and the holder together with the holder provides a sufficient degree of heat insulation to be able to hold the drinking device filled with warm liquid without risk of burning.
A further property with which the insulating effect of the container can be expressed is the heat resistance. The heat resistance of the material of the container is preferably at least 0.5 m2 / KW for drinking devices with a container tightly enclosing the cup and at least 0.25 m2 / KW for drinking devices with a container "broadly" enclosing the cup with an insulating air layer .
The softening temperature of the material of the cup is preferably higher than 80 ° C. Otherwise the cup would melt, or at least become too weak for safe use, if hot water is poured into it. The softening temperature is further preferably at least 100 ° C, so that the cup is also resistant to almost boiling water. Tea is preferably brewed at a temperature of 92 ° C, in order to obtain a good-tasting tea.
When the cup is made from PLA or CDA, it is advantageous that the cup is compostable. The cup is further preferably made from a material from renewable natural sources.
Further properties of the container are dimensional stability and shatterability. Although these are relative concepts, it will be clear that a holder preferably does not deform or hardly deform when gripping the drinking device. Although some elastic compressibility is not desirable, it is acceptable to prevent the rigidity of the drinking device from having to be over-dimensioned. In the assembled condition of the cup, the holder must not deform in such a way that the user is able to grasp it in such a way that there is a reasonable chance that liquid will flow over the rim of the cup. With splinterability it is expressed that when the container is compressed after use, the container preferably does not present a risk of injury to the user, for example as a result of the "breaking" of the container, or if it is broken due to sharp break edges. This last characteristic also applies to the cup.
The cup is preferably made from a material from the group of thermoplastic polymers (food grade), for example polypropylene (PP), polyethylene terephthalate (PET), polylactic acid (polylactic acid, PLA) or cellulose diacetate (CDA). Of the preferred materials mentioned, PP is particularly suitable because of the processing properties and for cost reasons. The said materials, however, all contain a combination of properties suitable for the cup.
In a preferred embodiment according to the present invention, the outside of the side wall of the cup, in the assembled state of the drinking device, is close to the inside of the side wall of the container. Thus, the resistance to the tearing apart of the holder and the cup is increased. Furthermore, in such an embodiment, the holder offers the cup a better support, in particular when a very hot liquid is present in the cup.
In a preferred embodiment according to the present invention, a lid is provided with which the cup can be closed at the top edge. The lid is separate from the cup prior to use, that is, before filling the cup with liquid. After filling the cup, the lid can be placed on the top edge. This prevents hot liquid from flowing out of the cup, for example when a user walks with a filled drinking device. Moreover, the lid provides a greater rigidity for the drinking device.
According to a second aspect, the present invention relates to a stack of drinking devices according to the previous aspect of the present invention, wherein the drinking devices are preferably provided with a tapered edge and in which a cup and a holder alternate each other. Thus, for example, a catering employee who issues drinks, for example hot drinks and in particular tea, can always take a combination of a holder and a cup from or from the stack. This is facilitated according to the present invention if a holder and cup from the stack are always attached to each other or are otherwise held together, such as for instance clampingly.
The present invention will now be further elucidated with reference to exemplary embodiments of drinking devices according to the present invention and with reference to the following figures, in which:
Figure 1 shows a perspective side view of a first embodiment of a drinking device according to the present invention;
Figure 2 shows a perspective bottom view of the drinking device of Figure 1;
Figure 3 shows a vertical sectional view of the drinking device of Figure 1; and
Figure 4 shows a perspective side view of an alternative embodiment of a drinking device according to the present invention;
Figure 5 is a vertical sectional view of the drinking device according to Figure 4; and
Figure 6 is a perspective side view of yet another drinking device according to the present invention.
Now looking at figures 1, a perspective view is shown of a tea cup 1 as a drinking device according to the present invention. Figures 2 and 3 show the tea cup in bottom perspective view and in vertical sectional view, respectively. Tea cup 1 comprises a transparent polypropylene (PP) cup 2 and a cardboard holder 3 partially surrounding the cup. PP is a material that does not give off a taste or odor when a user drinks hot drink from it and is therefore excellent for keeping tea . Cup 2 has a flat bottom 4 at the peripheral edge, a side wall 5 of which extends obliquely upwards at an angle α to an upper edge 6 which is formed with a skirt 7 which is folded back outwards. Holder 3 has a flat bottom 8 which extends slightly beyond. the peripheral edge of the bottom 4 of the cup protrudes. A side wall 9 also extends upwards at an angle α with respect to bottom 8. However, the bottom wall 9 protrudes a little beyond the bottom 8 on the underside and thus forms a collar 10. Side wall 9 does not extend equally far up everywhere and thus has a tilt-shaped upper edge 11. The bottom 4 of the cup 2 and the bottom 8 of the holder 3 are glued together by means of glue 12.
As can be seen in particular from Figure 1, the holder 3 has two opposite higher parts which are separated by two opposite lower parts. The higher parts provide a part where a user can grasp the holder 3, and therefore the tea cup 1, well. The lower parts provide "see-through" through the holder 3 and the transparent cup 2. A user can thus properly judge the color of beverage contained in the tea cup 1. With tea, the color is a measure of the strength of the tea. The glue spot 12 not only functions as a fixing means for fixing the holder 3 and the cup 2 together, but also as a spacer. Due to the mutual distance thus achieved between the bottoms 4, 8 of the cup 2 and the holder 3, an insulating layer of air is present between the bottoms 4, 8. There is also an insulating layer between the side walls 5, 9 of the cup 2 and the holder 3. air layer is present, which is the result of the dimensioning of the cup 2 and the holder 3, and possibly the glue spot 12. Due to the insulating action of the cardboard of the side wall 9 of the holder 3 in combination with the air layer, the tea cup 1 can a user can be grasped without the heat from the beverage contained in the cup 2, such as hot tea, being transferred to the user's hand in an annoying way. In practice, users often support a tea-cup of the "take away" type with the little finger or with one or more fingers at the bottom. The collar 10 in that case forms an additional spacer between the bottom 4 of the cup 2 and the little finger or finger (s).
Figures 4 and 5 show a perspective side view and vertical sectional view, respectively, of an alternative tea cup 21 according to the present invention. Tea cup 21 has a cup 2 as in figures 1 to 3 and a holder 23 of EPS foam. The same or comparable elements with respect to the previous embodiment of drinking device 1 are denoted in Figures 4 and 5 by the same reference numerals and by 20 incremented reference numerals as in Figures 1, 2 and 3. The side wall 29 of container 23 encloses the side wall 5 of cup 2 closely. EPS foam has a relatively low heat conductivity coefficient, so that an insulating air layer is not necessary. Supported by the friction between the tightly enclosing EPS of container 23 and the PP of cup 2, a clamp connection is provided, as it were, whereby cup 2 is difficult to detach from container 23. Holder 23 has a side wall 29 with a higher part which extends further with respect to holder 3, namely up to a skirt 7 of cup 2. In this embodiment a collar is missing on the underside of the holder 23. Because the EPS has a higher has an insulation value than cardboard, it is easier to provide a sufficiently large insulation on the bottom 28 of the holder 23.
Figure 6 shows a perspective view of yet another embodiment of a tea cup 41 according to the present invention. The same or comparable elements with respect to the previous embodiment of drinking device 1 are indicated in Figure 6 by the same reference numerals and by 24 incremented reference numerals as in Figures 1, 2 and 3. Tea cup 41 has a cup 2 and a holder 43 of corrugated cardboard with in contrast to holder 3, an upper edge 51 of side wall 49 situated in one plane and extending from the bottom 48 to about 1/3 of the side wall 5 of cup 2. Corrugated cardboard, just like the cardboard of holder 3 of figures 1, 2 and 3, provides a well-printable surface on which information or advertisements can be printed. Holder 43 fits closely with the inside of its side wall 49 against the outside of the side wall 5 of cup 2. The bottoms 4 and 48 of the cup 2 and the holder 43, respectively, are glued together. In comparison with drinking devices 1 and 21, drinking device 41 with relatively short side wall 49 provides a relatively small holding part, but a relatively large see-through part.
The present invention is illustrated in the accompanying figures and the foregoing description with reference to only a few exemplary embodiments of drinking devices. It will be clear, however, that many variants, whether or not obvious to those skilled in the art, are conceivable within the scope of the present invention, which is defined by the following claims. For example, other materials may be used for the cup and the container which have properties specified in claim 1 and therefore fall within the scope of the materials defined as such indirectly in claim 1. The shapes of the cup and the holder can differ from the examples shown. A lid can also be provided which after filling of the cup can be attached to the cup in a manner known per se, engaging the upper edge of the cup. The lid can be provided to prevent spillage, it can also provide the cup with more rigidity. Although the drinking device is always referred to in the description as a tea cup, the drinking device can also be used excellently for holding and drinking other hot or cold drinks, such as coffee, soup, chocolate milk or soft drinks.
