Abstract

PROBLEM TO BE SOLVED: To ensure an extreme safety against unscrewing of a closure by children and to provide a sealing property against any kind of tampering from outside by a method wherein screwing at a neck part of a container is made unloosable unless a considerably great pressure is applied downward in the axial direction to an elastic means interposed between a cap and a hood. SOLUTION: An elastic means 10 is constituted of two elastic inner teeth 11 engaged with an inclined surface at the upper end of a hood 4. A number of first wings facing outward are provided on the periphery of the hood 4, and a cap 3 has a number of second inner wings provided at positions corresponding to the first wings of the hood 4. When the cap 3 is pressed downward in the axial direction, the teeth 11 of the cap 3 easily deform elastically, and the first and second wings release screwing of the cap 3 to the hood 4.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container with a safety closure, and more particularly to a container with a safety closure for medicines and the like.

[0002]

BACKGROUND OF THE INVENTION Drop bottles are known which contain pharmaceutical substances, cosmetics and dietary products in liquid form or in powder or granule form and are fitted with safety closures which are forbidden for removal by children. These closures usually consist of a closure member screwed onto the neck of the container and a safety cap rotatably coupled to the closure member. The cap is not removable, but is not pressed down to engage a set of teeth or bumps formed on the periphery of the closure member head and a set of teeth inside the top of the cap. Simply rotates.

[0003] The connection between the two sets of teeth is to loosen the screwing of the closure member by applying a loosening operation by turning the cap in combination with the axially downward pressure, with the cap firmly connected to the closure member. Can be. When the above-mentioned pressurizing action is lost, the elastic member interposed between the flat closing surface of the cap and the flat closing surface of the closing member and compressed during the operation of turning and loosening the cap is used to form two sets of teeth. A spacing force is exerted between the cap and the closure member which tends to loosen the engagement and return the cap to a freely rotating safe position.

[0004] Conventional containers also include a "tamper evident collar" mounted on the inside of the closure member and formed to fit snugly into the neck of the container at the bottom and act as a seal. -evident collar
], A safety closure comprising a third member with In this way, the closure is screwed into the neck of the container and sealed by means of a collar that is easily recognized as being operated, while the cover or cap only needs to be pressed down firmly as described above. Can be removed.

[0005]

These drop bottles are free of drawbacks, including the fact that most of them do not have a safety closure, as well as a collar that is easily operated. I can't say. If the aforementioned collar is present, it is an added part, and thus, with increasing material used, is accompanied by increased production, adjustment and assembly costs. Further, in many cases, the outer sealing collar needs to be completely removed and peeled from the neck of the container, thereby causing environmental pollution.

The present invention has been made in view of the above problems, and is extremely safe for removal by a child, and at the same time has a sealing property against any external mischief. It is an object of the present invention to provide a container with a safety closure, particularly a container for medicines and the like, which does not require the use of a general member and can reduce not only the amount of material used but also production and assembly costs.

The hood 4 has a sealing ring 6 at the bottom and an inner surface that fits tightly to the outer surface of the neck 7 of the container 1. The inner surface of the hood 4 has a thread 8 which is located close to the mouth 5 and which engages with the external thread 9 of the neck 7. The cap 3 has two resilient inner teeth which engage the inclined surface of the upper end of the hood 4 to prevent its screwing from loosening from the neck 7 without applying considerable pressure axially downwards. An elastic means 10 constituted by 11 is provided on the upper part.

A plurality of first wings 12 directed outward are provided around the hood 4, and the cap 3 is provided with a number of inner second wings disposed at positions corresponding to the first wings 12 of the hood 4. It has a wing 13. The wings 12 and 13 are inclined with respect to the radial plane and prohibit rotation of the cap 3 with respect to the hood 4 to loosen the screw. The sealing ring 6 is connected to the hood 4 by a previously weakened bridge 14 and fits snugly on the surface of the neck 7 of the container 1.

When the hood 4 is pressed downward on the cap 3 in the axial direction, the hood 4 engages with a complementary projection 16 formed on the inside of the cap 3, and loosens the screwing of the hood 4 from the neck 7. A series of radial grooves 15 are provided on the periphery, which are directed towards the cap 3 which produces a rigid connection that can be made. The neck 7 has a positioning and supporting collar 17 having a number of outer notches 18 that couple to the sealing ring 6.
At the bottom.

Inside the ring 6 are formed a plurality of longitudinal teeth 19 which cooperate with corresponding notches 18 formed on the surface of the support collar 17. More advantageously, the hood 4 has at its lower part a protruding peripheral rim 20 which locks with the rim 21 at the bottom of the cap 3. As shown in some figures, the container 1 has a conventional, axially-centered tubular member 22 for dispensing a medicament into its mouth 5 in a drop-wise manner.

The hood 4 has flow control means inside and at the top formed by a plug member 23 for sealing the tubular drip member 22 of the mouth 5. Even more advantageously, the cap 3 has a plurality of vertically upstanding portions 24 on the outside to facilitate gripping by the operator when unscrewing and simultaneously applying downward pressure. Have.

An important characteristic of the hood 4 is that the teeth 11 of the cap 3 are formed in a bell shape so that the cap 11 is easily elastically deformed when the cap 3 is pressed downward in the axial direction. , Other embodiments of the hood 4 are possible. The invention has a safety closure with its intent and purpose, i.e. a safety closure with a sealing mechanism, and consists of only two cooperable members, ensuring a safe closure against external tampering or child removal. In particular, it is possible to provide a container for medicines and the like.
