Description

CLOSURE COMPRISING A HINGED LID < RTI ID = 0.0 >

The present invention relates to a stopper for a container, the stopper comprising a base portion and a hinged lid. The stopper can be fastened to the container opening of the container and has an exit opening. The hinged lid can pivot about the pivot axis toward the base portion.

This type of plug is known, for example, from WO 2005/090185 A1. The stopper may be placed in a bottle filled with a liquid cleanser. When in the closed position, the hinged lid closes the exit opening of the base portion. In this case, the cleaning agent can not escape through the container opening or the cap. When the hinged lid swings out to the open position, it is possible to open the exit opening, so that the detergent can be removed from the bottle.

In addition to the detergent sector, existing means of trading products are being supplemented by new distribution channels through e-commerce platforms. In this case, the product of the primary packaging (e.g., a cleaning agent or cleaning agent in the bottle) is placed in the shipping packaging (shipping box) and transported to the customer via the parcel service.

The load on the primary packaging or product can not be precisely defined when shipped to the customer. First, customers can not specify conditions during shipment. Shipping packaging can be exposed to different temperatures, vibrations and impacts. The shipping packaging may drop at different heights during transport.

Moreover, different padding may be used within the shipping packaging. The amount of padding used is also varied. Products are also sometimes shipped without any padding. The different sizes of the shipping packaging and the location or orientation of the primary packaging within the shipping packaging affect the loading of the primary packaging as it is shipped to the customer. Also, it is not uncommon for different products with correspondingly different primary packaging to be packed together in a single shipping package. The interaction between these different products can not be measured in advance.

Due to the above uncertainties associated with deployment via an e-commerce platform, there is a stringent requirement for mechanical stability of the primary packaging of the product. Tests relating to the shipment of liquid products (e. G. Detergents or cleaning agents) via electronic commerce channels have proven that the liquid product often escapes accidentally, especially from a cap which may be deformed or even destroyed during shipping. However, not only the illnesses that have leaked but also the corresponding results are considered unacceptable and very uncomfortable to customers.

The problem to be solved by the present invention is thus to develop a cap comprising a base portion and a pivotable hinged lid so that the container provided with this kind of cap is better suited for being distributed through an electronic commerce channel.

The problem addressed by the present invention is solved by a combination of features according to claim 1. Embodiments of the invention may be found in the dependent claims.

According to the invention, the base portion has two opposing shoulders, the hinged lid is between the two shoulders in the closed position, and the two shoulders project beyond the hinged lid in the vertical direction. Therefore, the shoulders protect the hinged lid from shocks or loads coming from the sides or from above. This reduces the risk of the hinged lid being broken and open or damaged when receiving this type of rod. This greatly reduces the risk of accidental product leaking from the container.

In one embodiment, each of the opposing shoulders has an upper shoulder edge that extends parallel to each other. In this case, the two upper shoulder edges form a substantially rectangular protective space in which the hinged lid is located when in the closed position. The laterally arranged shoulders absorb the impact from the side and from above.

The terms "vertical direction" and "vertical impact" respectively assume that the stopper according to the present invention is located in the container opening and that the container is standing at the bottom of the container and the container opening upward. In the closed position, the hinged lid is in a generally horizontal plane. The hinged lid swinging upward from the horizontal plane allows the hinged lid to be moved to the open position. In this process, the hinged lid leaves the protective space formed by the shoulders. When the container opening is oriented so as to be tilted with respect to the vertical rather than upward, the term "vertical direction" etc. should be construed accordingly.

In one embodiment of the invention, the upper shoulder edge extends in the longitudinal direction extending transversely to the pivot axis. In this case, the protective space defined by the shoulder edges or shoulders can be adapted exactly to the shape of the hinged lid. The distance between the shoulder edges can be kept to a minimum, thus providing enhanced protection to the hinged lid. The distance between the shoulders is preferably 0.01 to 5 mm wider than the width of the hinged lid. The width of the hinged lid can be 4 to 45 mm.

The upper shoulder edge can protrude beyond the hinged lid over substantially its entire length. If the hinged lid has a first region facing the pivot axis, a second central region and a third region facing away from the pivot axis, the upper edge projects over the hinged lid in all regions, And provides good mechanical protection. However, the present invention also includes embodiments wherein, for example, only the upper shoulder edge projects beyond the second central region and the third region. In this case, the shoulder edge does not protrude beyond the first area, in which case the shoulder does not provide any directional protection from impact from above. Preferably, with respect to the entire longitudinal extension of the hinged lid from the pivot axis to the outer end, the shoulders project beyond 70, 80 or even 90% of the hinged lid. The overall longitudinal extension may take a value of 20 to 80 mm.

The base portion has a receiving portion for the hinged lid and from the receiving portion it is possible for the inner shoulder wall of each shoulder to extend vertically (90 占 10 占 from the upper shoulder edge). In this case, the height of the inner shoulder wall is higher than the vertical height of the hinged lid. The excess height (the offset between the shoulder and the hinged lid or the difference between the vertical height of the hinged lid and the height of the inner shoulder wall) may be between 0 and 5 mm, preferably between 0.1 and 4 mm.

The offset can vary consistently or narrowly over the lengthwise extension of the hinged lid. If the hinged lid has, for example, a curved shape in its longitudinal extension, the individual shoulder edges may follow this shape and be curved with the same or similar curvature. The base portion of the base portion can also be bent or curved.

In one embodiment, the hinged lid has a U-shaped cross-section with two legs and a base interconnecting the legs. In this case, when the hinged lid is in the closed position, the open ends of the legs can be supported against the base portion of the base portion. The legs preferably extend parallel to the inner shoulder wall of the shoulder.

The stopper may be integrally formed, and conveniently the base portion is connected to the hinged lid by a film hinge. Thus, the stopper can be easily manufactured as an injection-molded part. Preferred materials are plastic materials, in particular polyethylene or polypropylene.

In order to make it easier to open the hinged lid, suitable means such as grip grooves or handles can be used to increase the degree of grip. It may also be considered to make it easier to open and close the hinged lid by providing a grip area made of a soft material (e.g., a thermoplastic elastomer).

The base portion may have a latching projection on an end opposite the pivot axis, the latching projection forming a latching undercut for a latching lug of the hinged lid on the lower face. In this case, the upper surface of the latching projection may be provided with an inclined or rounded portion for the latching lug to facilitate closure of the hinged lid. The interaction between the latching projection and the latching lug secures the hinged lid in the closed position, even if the plug is deformed by the outer rod.

The present invention will be described in more detail with reference to the embodiments shown in the drawings.

1 is a sectional view of a cap according to the present invention.
2 is a sectional view taken along line II-II in Fig.

Figures 1 and 2 show a closure 1 comprising a base portion 10 and a hinged lid 30. The base portion 10 is rigidly connected to the container 2 (only partially shown) with the upwardly facing container opening 3. The stopper 1 can be fastened to the container 2 or to the container opening in a different manner, for example by being inserted into the interior and fixed by catch and threaded inside. The container may be a plastic bottle having a container volume of 75 ml to 5000 ml. Plastic bottles may store liquid products such as liquid cleaners or detergents (e.g., automatic dishwasher detergents).

The base portion 10 includes a skirt 11 which abuts the lower peripheral rim 12 of the container 2. The skirt 11 transitions to the first shoulder 13 and the second shoulder 14. Since the base portion 10 is symmetrical about the central axis 4, each of the shoulders 13 and 14 has the same structure. Thus, the description of the first shoulder 13 applies similarly to the second shoulder 14. [

The first shoulder (13) has an upper shoulder edge (15). The inner shoulder wall 16 extends from the receiving portion 17 of the base portion 10 for the hinged lid 10 to the upper shoulder edge 15. In the illustrated embodiment, the angle between the receiving portion 17 and the inner shoulder wall is about 90 degrees, which means that the angle can vary from 85 degrees to 125 degrees as defined by the present invention.

1, the hinged lid 30 is connected to the base portion 10 by a film hinge 31. In this case, the film hinge 31 defines a pivot axis for the hinged lid 30, which extends perpendicular to the plane of drawing in Fig. Figures 1 and 2 show the hinged lid 30 in the closed position.

The receiving portion 17 extends slightly from the film hinge 31 and the receiving portion may have an area where the hinged lid 30 is not supported. A circular exit opening 18 is formed in the center of the receiving portion 17 and a cylindrical stopper 32 of the hinged lid 30 is located in the opening. The stopper 32 closes the outlet opening 18 so that the liquid product located in the container can not escape through the container opening 3 to the outside. As can be seen, the downwardly directed connection piece 19 of the base portion 10 protrudes into the container opening 3.

The hinged lid 30 has the shape of a folded strip having a U-shaped cross-section. The cross section includes two parallel legs (33) and a base (34) perpendicular thereto. In this case, the length of the legs 33 is smaller than the height of the inner shoulder wall 16. Thus, there is an offset R between the upper shoulder edge 15 and the base 34. Thus, the first shoulder 13 protrudes over the hinged lid 30 in the vertical direction. Naturally, this also applies to the second shoulder 14, by mutatis mutandis. 2, the entire hinged lid 32 is below a virtual connection line (not shown) between the upper edge 15 of the first shoulder 13 and the upper edge of the second shoulder 14. That is, the two opposing shoulders 13, 14 form a protective space for the hinged lid 30. This protection space prevents impacts on the stopper from lateral or upward having a direct effect on the hinged lid 30. This reduces the risk that the hinged lid 30 is released from the illustrated closed position and the liquid product can escape the container.

Figure 1 shows that the shoulders 13,14 or their upper edges 15 extend from the film hinge 31 up to the opposite end 35 and extend beyond the hinged lid 30 over its entire longitudinal extension, . However, in accordance with the present invention, it is preferred that the shoulder (13, 14) is of the plug type, which protrudes vertically beyond the main part of the hinged lid (30) with respect to the longitudinal extension. In the vicinity of the film hinge, the offset R, i.e. the excess height of the upper shoulder edge 15 relative to the hinged lid 30, may be moved away from zero at a point marked S or a value less than zero. However, the hinged lid 30 is protected primarily from external shocks by the excess height of the shoulders 13,14.

At the opposite end 35, the hinged lid 30 has a latching lug 36 that engages the latching projection 20. On the lower surface, that is to say on the side facing the container 2, the latching projection 20 forms a latching undercut, on which a latching lug engages when the hinged lid is in the closed position. The latching projection 35 is rounded at the top surface. The rounded protrusions help push the hinged lid 30 into the closed position shown here.

In order to open the hinged lid 30, a finger grip 37 is provided at the end 35. By placing a finger on the finger grip 37 and pushing the end 35 upwardly or deforming the end it is possible to release the latching connection between the latching lug 36 and the latching projection 20, 1, the hinged lid 30 can be turned upward counterclockwise. In this process, the stopper 32 comes off the outlet opening 18 to open the opening. The film hinge 31 may be designed to push the hinged lid 32 to a predetermined open position by an elastic restoring force (e.g., offset by 180 degrees relative to the illustrated closed position). To close the hinged lid, the hinged lid rotates clockwise until the latching lug 36 abuts the upper surface of the latching projection 20. The compressive force from above pushes the latching lug 36 outwardly as a result of the rounded portion, thereby allowing it to pass over the latching projection 18. It is therefore locked in the position shown.
