Description

LOCK LID FOR BOTTLES

[001] This invention patent is about a new lid with lock for bottles, belonging to the area of packaging in general, more particularly it is a lid equipped with a horizontal tear close to the edge, which allows the locking of the same on the annular protrusions or crimp valves of bottles in general, preventing access by children and also allowing easy handling, through which very advantageous practical, safe and functional results are obtained.

[002] Various types of bottles for packaging different products are known in the state of the art, and in particular in the pharmaceutical and personal hygiene area, the big challenge is to find a lid that can be used on different bottles, which at the same time It is easy to use and has a safety lock to prevent children from accessing it.

[003] According to the CETEA Packaging Technology and Development Bulletin, vol. 25 - n° 1, January/February 2013, we have that: “According to the National Toxic-Pharmacological Information System (SINITOX), based at Fiocruz in Brazil, approximately 30.7% of poisoning cases are due to medicines and 11 .4% for household cleaning products. Seeking to minimize these accidents, packaging has been developed to act as a physical barrier between children and products that are dangerous to their health. ”

[004] In this sense, we have in the state of the art some screw caps and a safety device using internal projections that, combined with projections on the neck of the bottle, function as a lock, providing two types of closures. In fact, a locking device in addition to the closing thread provides greater security, but entails A major inconvenience is the difficulty of opening the packaging. Furthermore, another inconvenience is perceived in the great difficulty of its manufacture, requiring different molds, which results in a high production cost, making the packaging more expensive without adding value to the packaged product.

[005] As part of the state of the art, we highlight document US5551582 filed on 09/29/1995 referring to “TORSION RESISTANT CLOSURE AND CONTAINER FOR CHILDREN”, where according to its summary we have: “t/ closure container package child-resistant, snap-in and twist-lock, which is opened by squeezing and deflecting the diametrically opposed side portions of the closure to engage the cam followers, which cam into the container so that subsequent rotation causes axial displacement and opening movement of the container closure. Guide members prevent distortion of the lid to keep the sealing surfaces and adjacent surfaces of the lid and container aligned with each other and prevent distortion to expose surfaces that can be grasped by fingers or teeth in an effort to open the lid and container in a manner other than the intended method of tightening and twisting the lid relative to the container.”

[006] As stated above, this document presents, in addition to the threads, projections that work as a second lock, requiring a twisting and turning effort to open the package when opening. Therefore, in addition to making it difficult to open the bottle, the lid has a complex construction requiring high mold costs and loss of productivity.

[007] Presenting the same problems mentioned above, we also highlight document FR2414005 deposited on 01/06/1978 regarding “CHILD PROOF LID LOCK - REQUIRING A COMBINED CLING AND SCREWING ACTION FOR RELEASE”, where according to its summary we have: “A child safety closure for a screw cap container comprises a combination of a screw on the bottle which has ramps along a path of external thread and a (plastic) cap with an internally threaded skirt with internal ribs that may interfere with the ramps in the bottle neck. The ramps and ribs are placed back to back to facilitate closing, but they lock during unscrewing. Interference can be overcome by distorting the profile of the lid skirt, applying radial pressure at suitable points identified by marks or tears on the outside of the lid.”

[008] Taking into account these problems of the prior art, the locking lid for bottles was developed, the object of the present invention patent, which provides a child safety locking device together with an opening facilitated through a single vertical movement. . Furthermore, it provides a simple construction with low production cost, thus solving the aforementioned drawbacks, in addition to providing other advantages arising from its design.

[009] The present invention patent will be better understood through the attached drawings, which schematically represent:

[010] According to the figures presented, the new locking lid for bottles comprises a cap (1) which is coupled to the bottle (2), more particularly to the annular protrusion (21) of the neck, which may originate from the bottle itself. bottle body (2) or equipped with a crimp valve.

[011] Said lid (1) is formed in a single tubular body, equipped on the front and back faces, close to the edge, with slots (11) proportional to the height of the annular protrusion (21), and on the sides with clamping regions (12 ) to unlock.

[012] Optionally in a constructive variant, the lid (1) will be equipped with flat walls (13) on the front and back faces, forming at the lower ends of the openings (11), the bases (14) and on the edge a ring reinforcement ( 15).

[013] According to figures 9 to 12, in a second constructive variant, the lid (1) will be equipped with an elliptical body (30), following the shape of the bottle (2) and will be equipped on the front and back faces with flat walls (31) recessed to allow the annular protrusion (21) of the vial aerosol device to partially fit into the slots (11).

[014] According to figures 13 and 14, in a third constructive variant, particularly for bottles equipped with a screw cap (40), this will be provided on the edge with an annular protrusion (41) for coupling to the slots (11) of the cap (1), which will be used as an overcover and will be equipped with volumetric markers (50).

[015] According to figures 15 and 16, in a fourth constructive variant, particularly for bottles without aerosol valves, equipped with a neck (22) and annular protrusion (21), the lid (1) will be internally equipped with a projection (60 ) which is fitted internally into the respective neck (22) of the bottle (2).

[016] According to figures 17 to 19, the new lid with lock for bottles, thus designed, can be applied to different bottles, made of plastic, aluminum or glass, as long as they are equipped with a circular or elliptical protrusion on the respective neck. .

[017] To do this, simply move the lid (1) vertically until part of the protrusion (21), located on the neck (22) of the bottle (2), fits, with a little pressure, into the slots (11) of the lid. . Once this is done, a child will not be able to remove the lid, since to unlock the lid (1) of the bottle (2), the region (12) must be pressed and simultaneously the lid (1) must be moved vertically.

[018] The locking lid for bottles, object of the present invention, has several advantages compared to its counterparts, including:

- Ease of handling;

- Provides a safety device for children;

- Provides a simple construction;

- Low production cost;

- Allows inclined parallels to be applied to the sides of the lid, to form slots, where construction costs can be minimized with injection molds by not requiring drawers and providing a larger area for increasing the number of cavities in the same area and closing; It is

- Adds ease of handling with a safety lock without compromising the cost of packaging.

[019] The scope of the present invention should not be limited to the construction details and application, but rather only to the terms defined in the claims and their equivalents.
