DD225115A1 - CLOSING DEVICE FOR CONTAINERS - Google Patents

Abstract

The invention relates to a self-contained, form-locking and detachable connection for container parts. THE TASK OF PROVIDING FOR THE SEALING OF THE CONTAINER AND THE OPENING OF THE CONTAINER IN A MOVEMENT PROCESS IS ESTABLISHED BY COMMUNICATING THE MAJOR CONSTRUCTION ELEMENTS OF THE CONTAINER TO THE CONTAINER PART OF THE OPENING MOVEMENT. THIS CONCERNS AN OUTSTANDING SHOOTING BOX WITH A UPPER SUPPORT AND BREAKFAST FOR THE ARRANGEMENT OF A LOCK TRAP AND A SHUTTER PLATE. ALTHOUGH THE CLASP HOLDER HAS A LOWER HOOK THREAD FOR INTERMEDIATE WITH THE EDGES OF THE CONTAINING HOLDER, THE LOCK PLATE HAS AN OPENING HOOK AND IS DESIGNED ON AN END AS A HANDLEBAR FOR LIFTING. THE INVENTION IS PARTICULARLY SUITED TO THE APPLICATION TO SAME MULTIPURPOSE PLASTIC BOXES MANUFACTURED BY INJECTION MOLDING METHOD.

Description

embodiment

The invention will be explained below using the example of a closure for a multipurpose suitcase, the parts of which are produced by injection molding

 In the drawings show

Fig. 1 shows a section through a complete closure

Fig. 2 is a view of the back of the closure plate with the opening hook Fig. 3 is a view of the front of the closure latch Fig.4 a section through the receiving shaft.

The front surface of the container upper part 1 has a receiving shaft 3 protruding from its wall. The receiving shaft 3 is delimited in its length by two trough-shaped supports 2. In between, a vertical opening 4 is formed, while the vertical shaft wall contains a horizontally extending central opening 5. In the region of the closure device, the opening edge of the upper part 1 is formed blunt and the opening edge of the container base 15 ends as a projecting locking lip 16 with bevelled edge. The closure latch 6 is an additional flat completion part with a lower latching hook 8 for cooperation with the locking lip 16 and an upper web-shaped collar 7 as an abutment. The locking in the shank takes place by means of frontally formed latching lugs 11. The central region of the planar part is with a horizontally extending aperture 10 and provided with an integrally molded pressure spring 9 in each case. They support the closure latch 6 against the inner contour of the outer wall of the receiving shaft 3 and cause the latching action after completion of the closing movement of the container upper part. With the closure plate 12, the cover of the functional closure elements on the container front and the release of the closure latch 6 together with the handling of the container top part 1 when opening purposes. For this purpose, the upper end of the closure plate is bent and forms with the support 2, the pivot point for the lever movement. On the inner contour of the closure plate a two-sided undercut resilient opening hook 13 is formed. With his help done after completion of the closure device through the apertures 5 and 10, the transmission of the tensile force from the handle 14 on the latch hook 13 to the opening of the multi-purpose suitcase. The Verschiußeinrichtung can thus be opened without the aid of a second hand. It also offers the advantage that the completion of work in the production limited to the top and obstruct the entrance no disturbing details access. The functional parts are arranged concealed and inadvertent compressive stress on the closure plate 12 during use does not lead to release of the latching closure.

Claims (3)

Invention claims: 1. closure device for containers, which is arranged at the opening edge of the container parts to be closed, characterized in that the opening movement exporting container part (1) has an outer receiving shaft (3) with at least one upper support (2) and a horizontal opening (5) a closure plate (12) and a vertical opening (4) for a closure latch (6) and that the opposite container part (15) has a locking lip (16) with beveled edge. 2. Closing device for containers after Pkt.!, Characterized by a completed as a completion part of the closure trap (6) with an upper collar (7) and frontal locking lugs (11) and by at least one lower latching hook (8) parallel to the slope of the locking lip (16) extending edge and also at least two pressure springs (9) for support on the wall of the receiving shaft (3). 3. Closing device for containers according to item 1 and 2, characterized in that the closure plate (12) has a container contour adapted vertical course and with an upper bend, which with the support (2) forms its fulcrum, and at the opposite end as a handle (14) has been formed and that on its inner contour a resilient opening hook (13) is formed, which projects through the openings (5) and (10) and allows the release of the closure latch (6). For this 1 page drawing field of use The invention relates to a device for self-closing, positive and releasable connection of container or housing parts to each other. It is particularly suitable for the closure of multipurpose suitcases made of plastic material. Known solutions The applicant already manufactures a multipurpose plastic case with snap closure. This consists of a cover arranged on the resilient tongue whose undercut engages under a horizontal web on the lower part and must be released to open by pressure on the tongue. The opening process requires the use of both hands for the release of the tongue and the lid operation. According to an older proposal (DD 47336), the closure of the container parts by a tab-like closure member, which is positively connected to a container part and engages in the closed position under a corresponding recess. The opening of the closure takes place by pressure on the tab-like closure member, wherein an unintentional operation can not be avoided. When opening, the leading edge of the recess proves to be a hindrance to handling. The structural elements of the closure, including its attachment, protrude beyond the container dimensions and can cause damage and injury. In another known solution of a closure for molded containers (DE 3235879), an upstanding latch incl. Horizontal rib on the locking surface with an opening into engagement. By pressing the latch, the shutter is opened. Due to its constructive design, this design is material intensive and space consuming. Common to the known solutions is the arrangement of the closure device on the outer opening frame of the container parts to be closed and the opposition of the movements when releasing the closure ice (pressure) and the opening of the container top or lid (pull). crfindungsziel With the invention, the usefulness of closure devices of the type mentioned influencing properties to be improved. An unintentional opening of the container is to be excluded and its handling when opening is to ensure one-handed. Essence of the invention The problem consists in the formation of structural elements on the contours of the container parts to be joined together and of completion parts, which allow the release of the closure and the opening of the container in a movement. When closing the Behälterteiie automatically form a positive connection caused by locking. An injection-molded design as well as the plastic completion with low expenses are to be secured. The inventive solution is that the opening movement exporting container part is provided with an outer receiving shaft with at least one upper support and a horizontal opening for a closure plate and with a vertical opening for the arrangement of a closure trap. The opposite container part has at its opening edge only a locking lip with bevelled edge. As a closure trap enters a flat completion part with an upper collar and front locking lugs in the vertical opening of the receiving shaft to the arrangement. At least one lower latching hook of the closure latch is provided with a parallel to the locking lip of the other Behäiterteils oblique edge. A central, horizontally arranged aperture for receiving the closure plate and at least two molded-on pressure springs for supporting the closure latch on the wall of the receiving shaft are further features of the closure trap. The closure plate is a flat component with a contour adapted to the container contour vertical course and an upper bend, which acts as a fulcrum at its end with the support on the receiving shaft and is formed at the opposite end to engage behind grip. The inner contour of the Verschlüßplatte has a resilient opening hook which protrudes through the horizontal openings of the receiving shaft and the closure trap and allows the operation of the closure trap when opening. This is done by train at the handle end due to leverage and leads to the release of the latching hook of the locking lip in subsequent opening movement of the container part without grasping. The closing movement causes a sliding of the closure latch with the slope of the latching hook on the chamfered locking lip and the engagement in the closed position.
