Abstract

The spray insert is connected to the bottle neck by a screw connection, resilient connection with draw tab or shrink foil connection with separator such as a radial perforation. After removing the insert the residual contents (5) therein can be emptied onto the hand. ADVANTAGE/USE - For shampoo bottles etc. There is less waste for better economy and less strain on the environment during disposal.

Description

The invention relates to a bottle according to the preamble of Claim 1.

Such bottles come in a variety of different types Known designs that serve a metered Partial liquid quantity by pressing on the bottle wall to be able to selectively remove.

The disadvantage of this is a slightly viscous Product - like shampoo - a non-removable amount of the Product in the area of the inner wall of the injection insert see.

It is therefore an object of the invention to avoid a additional environmental impact, the above-mentioned residual amount to make simple measures removable for the purpose of further Use.

This task is solved according to the characteristic part of the Claim 1. Further advantageous embodiments of the invention emerge from the subclaims.

The fact that the spray insert with a device for manual release of the syringe insert connection is provided the remaining amount can now be removed, that the syringe insert is removed from the bottle neck or is opened, causing the remaining amount from the large opening of the syringe insert can flow off, for example with one Shampoo on a palm, taking a rinse with something Water even the last rest is usable.  

Various devices for manual disconnection emerge from the subclaims.

The invention is based on several exemplary embodiments the figures and the description of the figures.

It shows:

Fig. 1 and 2 a first embodiment;

Fig. 3 shows a second embodiment;

Fig. 4 to 8, a third embodiment;

Fig. 9 shows a fourth embodiment;

FIG. 10 is a fifth embodiment;

FIGS. 11 and 12, a sixth embodiment.

In Fig. 1 a first embodiment of a crushable disposable bottle 1 is shown with a part connected to a bottle neck 2 spray applications 3 A. In the area of the inner wall 4 of the spray insert 3 A, a residual quantity 5 of a product that can no longer be removed via a spray opening 4.1 is shown. Because the syringe insert 3 A is provided with a device 6 A for manually releasing the connection 7 A, the remaining quantity 5 can be removed from the syringe insert 3 A - for example by draining off. The connection 7 A of the syringe insert 3 A with the bottle 1 consists essentially of sealing rings 8 which press against an inner wall 9 of the bottle neck 2 . This connection 7 A can be supported by a snap connection 10 .

In order to remove the injection insert 3 , a tear-open tab 11 , which is connected to the spray insert 3 A by connecting webs 12 , is drawn in a circle, whereby the connecting webs 12 tear open and the injection insert 3 A is thereby detached from the bottle neck 2 . However, it can also be provided that the spray insert 3 A is only designed to be opened. For this purpose, for example, the area A and B of the tab 11 can be firmly connected to the injection insert 3 A, this area A, B then acting as a folding hinge ( FIG. 2).

. In the second embodiment of FIG 3 is a device 6 B - In addition, as to the Fig. 2 - the portion B integral with the spray insert 3 B, whereby the spray insert 3 is pulled B from the bottle neck 2 in pulling the tear tab 11.

A third exemplary embodiment of a spray insert 3 C is shown in FIGS. 4 to 8, a screw connection 13 being provided here as device 6 C for releasing the connection 7 C, for example by means of four threads 14 at the end of the bottle neck 2 and with four of them corresponding thread cams 15 which are arranged on the inside of the injection insert 7 C. For closing the injection opening a screw-cap 4.1 is provided with a spray orifice 4.1 occlusive closure pin 17 is provided 16th Further details emerge from FIGS. 5 to 8, with FIG. 6 representing a top view of FIG. 5 and FIG. 8 showing a view from below of the injection insert 3 C according to FIG. 7. For a better turning off of the injection insert 3 C from the threads 14 , this is provided with a knurling 18 .

Fig. 9 shows a fourth embodiment, in which a shrink film connection 19 or shrink tube connection 20 is provided as device 6 D for releasing the connection 7 D, which has a separating perforation 21 for manually separating the connection 19 , 20 . The perforation 21 can be provided all the way round, the injection insert 3 D then being removable, or the perforation 21 being interrupted at one point, as a result of which the injection insert 3 D can be folded at this point. For this purpose, a corresponding marking can be provided on the connection 19 , 20 . For the connection 19, 20 on the bottle neck 2 an annular projection 22 is provided which communicates with a further annular projection 23 on the spray insert 3 D, both projections 22 are provided with an axial distance 23rd

After the perforation 21 has been separated , for example by means of a fingernail, for the purpose of removing residual quantities, the injection insert 3 D is pressed out manually on the annular projection 23 . The projection 23 thus serves as a connection seat and for pressing out. The sealing ring 8 serves only as a liquid-tight connection.

In Fig. 10 a fifth embodiment is illustrated. Here, as a device 6 E for releasing a connection 7 E, an annular actuation projection 21 is provided, on which the injection insert 3 E can be pushed out of the bottle neck 2 manually, the connection 7 E - formed from sealing rings abutting the inner wall 9 of the bottle neck 2 8 - is solved.

A sixth embodiment is shown in FIGS. 11 and 12. The difference to the exemplary embodiment according to FIG. 10 is that instead of a projection 24 a pull tab 25 is provided which is provided with a corrugation 26 for better grip. However, it can also be provided that the injection insert 3 F is articulated at one point to the bottle neck 2 .
