Description

Plastic bottle with recess for holding a

drinking straw

The present invention relates to a plastic bottle, which is designed so that therein a drinking straw in a specially provided recess

Accordingly, the plastic bottle, together with the attached drinking straw, can be offered to the end user as a singular product. This type of plastic bottles with integrated

Drinking straw makes therefore the additional procurement of a separate drinking straw by the end user superfluous. The recess is in the

Plastic bottle generally designed so that the drinking straw is easily removable and protected from contamination.

Plastic bottles whose design is suitable for receiving drinking straws are known in various embodiments. For most of these plastic bottles, however, the drinking straw is difficult to remove for use and / or not stowable again. Often the drinking straw is also lost during transport and leads to annoyance at the customer. EP001552, for example, discloses a bottle with a drinking straw-like pouring spout as a refilling aid which can be stowed in a groove-shaped depression of the bottle wall. In use, the pipe should be placed on the extended nipple of a standard screw cap. As can be seen from the patent, the trough-shaped depression is designed so that the Trinkalm must be bendable. This makes it difficult or impossible for the end user to repeatedly stow the drinking straw.

US 4036392 discloses a disposable bottle cap having on its outer surface a recess configured to receive a folded drinking straw therein. The drinking straw must have two corrugated zones to allow for folding and stowing of the drinking straw in the recess. DE 2422419 discloses a combination container for a liquid, which has in its substantially horizontal top wall a groove for receiving a drinking straw. The groove is designed with a removable cap so that the straw can be removed by hand from the groove. As can be seen from the drawing, the drinking straw must be foldable in order to be able to find accommodation in the curved configuration of the groove.

The plastic bottles listed below reveal a drinking straw that, when stowed, is in direct contact with the inside of the plastic bottle contained liquid. In these embodiments, the plastic bottle for distribution to the end user can only be closed after the drinking straw has found together with the drink in the bottle recording.

KR1020010064538 discloses a square beverage package having a drinking straw positioned in a corner within the beverage package. When not in use, the drinking milk is completely stowed within the beverage package in a folded or compressed state and in constant contact with the beverage contained therein. In order to be able to drink over the drinking straw, this must be unfolded by the end user, and the beverage pack due to the corner position of the drinking straw constantly be held by the end user in a correspondingly inclined condition. DE 102007050000 discloses a drinking straw which has two predetermined bending points, so that it is divided into three parts and completely accommodated in a closed drinking bottle. The bottle can be closed during their production only after the insertion of the drinking straw. In addition, it is not guaranteed that the upper part of the drinking straw protrudes in sufficient length, so as to allow a suction.

JP 2005067658 also discloses a drinking bottle with a drinking straw integrated therein. In view of the above-mentioned bottles, the present invention provides an object to provide a plastic bottle, in which the depression is configured so _'that a simplified removal of the well and recovery of the straw is ensured in the recess.

This object is achieved by a plastic bottle with the features of claim 1. Further advantageous embodiments will become apparent from the dependent claims, and the meaning thereof is explained in the following description. In the figures, preferred embodiments of the subject invention are illustrated and explained in detail below.

Plastic bottle and its tear line, according to an embodiment of the invention; and FIG. 4 shows schematically a top view of the plastic bottle provided with a depression and the drinking straw positioned in the depression, according to an embodiment of the invention. Reference numeral 100 denotes a plastic bottle which has a recess 120. As schematically illustrated in FIGS. 1A and 1B, in one embodiment of the invention, the jacket wall 110 of the plastic flap 100 is designed such that it has a lower conical region 112 that extends from the base 111 towards the bottleneck 114 having. Instead of the conical region 112, a cylindrical region could also be provided. The lower conical region 112 of the jacket wall 110 opens into a gripping region 125 or into an upper conical region 113, which in turn tapers conically into a bottleneck 114, ie the lower conical region 112 is followed, directly or indirectly, by an upper tapered region 113. In one embodiment of the invention, the lower conical region 112 is higher than the upper conical region 113. In another embodiment of the invention, the lower conical region 112 is at least approximately equal to the upper conical region 113. In a further alternative embodiment of the invention the lower conical region 112 is less high than the upper conical region 113. In corresponding embodiments of the invention, the angle between the longitudinal axis Z of the plastic bottle 100 and the lower conical region 112 is greater than or equal to the angle between the longitudinal axis Z and the upper konis area 113.

The jacket wall 110 has a recess 120 which extends at least approximately in a straight line from above the standing surface 111 both through the lower conical region 112 and partly through a gripping zone 125 or partially into the upper conical region 113. In the upper conical region 113 or in the gripping zone 125, the depression 120 opens into a drinking straw barrel zone 126 arranged between the two conical regions 112 and 113. The Trinkhalmfasszone 126 is designed so that taken from the front and / or from above a drinking straw 130 with fingers so can be that with a simultaneous upward movement of the fingers in accordance with the rectilinear course of the recess 120, the straw 130 can be removed from the recess 120. As schematically illustrated in FIG. 1B, in one embodiment of the invention the recess 120 has a semi-cylindrical cross-section and optionally has at least one clamping bead 128 arranged laterally therein. This clamping bead 128 may, for example, extend over the entire length of the depression or be arranged only at least below the drinking straw barrel zone 126. Optionally, this clamping bead 128 can also be arranged on both sides over the entire length in the recess 120, so that the drinking straw 130 is held in a form-fitting manner in the recess 120.

The plastic bottle 100 is wrapped with a shrink-film tube 140, so that the entirety of the depression 120 is covered with the shrink-film tube 140. The drinking straw 130 is not damaged by the shrinking of the shrink-film tube 140. Shown schematically in FIG. 2A, support elements 127 are arranged laterally of the drinking straw cask zone 126. These support members 127 protrude integrally formed from the shell wall 110 radially so far forward that they support the straw 130. That is, the support members 127 form radially outwardly directed shell wall elements. Accordingly, the shrink film tube 140 is pressed against the support members 127 during shrinkage and thus comes not or only slightly with the drinking straw 130 into contact. In one embodiment of the invention, the support members 127 run in the direction of bottleneck 114 apart to the drinking straw cask 126 to expand. As shown schematically in FIG. 2B, the bottom 121 of the drinking straw cask zone 126 may have a change of direction 122 toward the bottleneck 114 so that the upper part 131 of the drinking straw 130 protrudes somewhat from the bottom 121 of the drinking straw cask zone 126 and thus can be grasped more easily by the end user , However, this is not necessary and thus the bottom 1212 can also extend over the entire length, as shown in FIG. 1A. Returning to Figure 2A, in one embodiment of the invention, the shell wall 110 has gripping aids 115 to provide increased grip of the plastic bottle 100 during pouring. In corresponding embodiments of the invention, the gripping aids 115 are formed by an at least partially or completely knurled surface 118 of the jacket wall 110. Although the grip is also increased by vertically extending bulges 116 of the shell wall 110, which form corresponding vertical gutters 117, the bulges 116 have the main task of increasing the turbulence in the product during the shaking process and thus maximizing foaming, the shake time shorten and foam the foam as fine as possible and homogeneous.

The inventive plastic bottle 100 is designed overall as a shaker. Such a shaker can be effective as a shaker only when the shaker is not completely filled and thus a sufficient space remains around the To fulfill shaker function. The present plastic bottle 100 is intended in particular to shake milk mixed drinks or slightly alcoholic mixed drinks foamy. As already mentioned, this requires a sufficient space. Such a standing on a shelf container which is usually made of PET and correspondingly transparent would irritate the buyer by the corresponding void. For this reason, it is advisable to attach in front of a printed shrink-film tube 144. This printed shrink-film tube 144 is accordingly hardly transparent. Such a standing in the frame plastic bottle 100 thus does not visually filled incomplete.

The consumer will recognize the plastic bottle 100 as a shaker and shake it accordingly. By appropriate instructions on the printed plastic film tube, he is then encouraged to remove the plastic tube in the upper area corresponding to the intended tear lines, so that now the original space is visible. Due to the corresponding vigorous shaking activity, however, this room is now filled with foam.

As shown schematically in FIG. 3B and briefly mentioned in connection with the description of FIG. 2A, a shrink-film tube 140 is wound around the plastic bottle 100, which covers the jacket wall 110 to such an extent that the drinking straw 130 inserted in the depression 120 is completely covered and thus protected against contamination. The shrink-film tube 140 has a desired tear line 145, which allows the separation of an upper part 142 from a lower part 141 of the shrink-film tube 140. The desired tear line 145 can be formed according to corresponding embodiments of the invention by a perforation and / or by a material weakening or thinning.

The desired tear line 145 is designed so that at least a part of the drinking straw cask zone 126 can be exposed. For example, a horizontal part 146 of the desired tear line 145 can be mounted below the gripping zone 125 or at least below the support elements 127. The tear line 145 has, from the upper edge 143 of the shrink-film tube 140, a limited direction in the direction of the base 111, i. downwardly extending portion 147A and / or 147B. These partial tear lines 147A, 147B open into the at least approximately horizontal circumferential and self-contained horizontal portion 146 of the desired tear line 145. The downwardly extending portion 147A is approximately perpendicular to the horizontal portion 146 and the downward portion 147B extends at an angle and / or curved toward the horizontal portion 146 of the desired tear line 145. The upper portion 142 of the shrink film tube 140 is opaque. This leaves the free space within the plastic bottle 100 before it is shaken, i. before foaming of the liquid contained in the plastic bottle 100, invisible, as previously described.

In one embodiment of the invention, the upper part 142 of the shrink-film tube 140 is provided with a tab 144 which is a Force introduction into the down-facing tear line 147A and 147B easier.

These predetermined tear lines can in principle be designed as double, parallel perforations. In particular, at the area of the parts 147 A and 147 B of the tear lines 145 that run downwards, a tab 144 can also be formed (not shown in the drawing), which enables an improved force introduction. Drawn is a variant in which the tab 144 laterally aligned with one of the two rope ripcords.

Shown in the drawing is merely a version with a single recess 120. However, it is quite conceivable to arrange two parallel recesses 120 relatively adjacent to one another. This allows a straw to insert, which has approximately in the middle of a harmonica-like bending range. In this case, insert the drinking straw into the two parallel depressions so that the harmonica-like bending area has a hairpin-shaped bend of approx. 180 °. The bend now comes in the Trinkhalmfasszone 126 and the drinking straw can thus easily pull out. In the version with only one recess 120, it makes sense to use a telescopically designed drinking straw. This is useful because the length of the recess is less than the height of the plastic bag. However, in the telescopically extended state, the drinking straw is longer than the height of the plastic bottle and thus can not fall into the bottle.

- π - An essential feature of the invention is also that the shrink film tube 140 extends beyond the lower end of the recess 120 away and sealingly abuts against the jacket wall 110. Preferably, the shrink-film tube 140 is even partially formed up to footing 111 extending. Thus, even after the removal of the upper part 142 of the shrink-film tube, a dense pocket is formed from the lower part 141 of the shrink-film tube and the depression 120. This ensures that liquid from the drinking straw remains trapped in the pocket so that the consumer does not get through leaking fluid spills.
