Abstract

Disclosed is a combined package container with screw pulling rod, solving the defects that the casing of the existing paste package deforms easily when using, the extrusion capacity is difficult to be controlled and the content in the package can not be extruded cleanly. The utility model utilizes a screw pulling rod to change the rotary motion into the linear motion; the screw pulling rod drives a piston to move under the guide of a nut; therefore, the content can fully be extruded when the piston moves in the container. When using, a pawl and ratchet mechanism can only rotate in a single direction; the pulling rod drives the piston to move upward along the screw track; the moving clearance and noise caused by the ratchet tip of the ratchet dropping on the ratchet root of the ratchet during the rotation of the pawl can prompt and control the extrusion capacity of the content in the container. The casing of the package does not deform in the using process; the using and the decorating functions of the package can be considered well. The utility model provides the manufacturers of the high added value paste products with a selection scheme of the package for small dose.

Background technology

Known paste (the comprising partially liq) packing of product has much adopted metal or plastic material to make flexible containers, as the packing of spongaion, toothpaste and cosmetics.This type of packing has functions of use and two kinds of requirements of binding and layout expressive function concurrently.The user exerts pressure by the outer wall to packing container, and it is outer for people to use to make that the packing container inner package is extruded to container.

For the producer, paid attention to the binding and layout expressive function of packing, utilize the elasticity of packing container material that the outward appearance of packing is remained unchanged substantially.Such packing, along with extruding of packing container inner package, the container internal pore can be increasing, and the user is the extrusion capacity of controlling packet packaging container inner package well, causes the shortcoming on the functions of use.If the producer has paid attention to the functions of use of packing, owing to constantly extrude along with packing inner package in the use, the binding and layout expressive function of packing is also in constantly distortion forfeiture.These two kinds of results do not meet the requirement of people to packing of product functions of use and binding and layout expressive function.

For consumers, the size of packing container is not only relevant with customer's consuming capacity, and is also relevant with customer's actual needs consumption.The customer is all the more so to the approval process of new product hansel.Packing container select the too little attention that both had been difficult for causing the customer, can not satisfy packing binding and layout designing requirement again; Packing container is selected to such an extent that make consumer group's scope narrow down too greatly again, is unfavorable for the popularization of product.For the treasure of high added value, people need find the solution of interests between a kind of producer of taking into account and the customer.

Summary of the invention

The utility model packing is made up of casing assembly and spiral extrusion type container assemblies: Package casing is expressed the binding and layout form content of packing, and the binding and layout designer can become cylinder with enclosure designs, cylindroid, square column, the geometric cross section of different shapes such as polygon post.The size of shell can design on demand, can design various character patterns and allow the customer further be familiar with the interior product of packing container.Shell also is the component part of whole device, behind ratchet, nut and the detail assemblys such as piston, spiral handspike on ratchet on the shell, resistance transduction bar and the container, the user grips the shell folk prescription to rotating packing container, the cavity volume of packing container is diminished along with the variation of rotational angle, force the packing material in the packing container to be extruded from the path aperture of extruding of container.As long as constantly the rotation packing container just can all be extruded the packing material of packing container inner chamber.

The utility model device is after the volume of packing itself is determined, the can amount of container intracavity can also be adjusted variation within the specific limits, to satisfy the divided dose forms may needs of high added value treasure.

The utility model device is owing to adopted function to separate the structure design of reorganization, make the packing material of packing container inner chamber push the metamorphosis that can not cause Package casing in the process of extruding, can satisfy the requirement of this two aspect of functions of use of packing container binding and layout design-calculated expressive function and packing container fully in rotation.

The specific embodiment

The utility model device can select for use materials such as rigid medical plastic or metal to make except that piston (5), and piston is selected medical grade rubber for use.Gag (0) enters container intracavity (10) back in the packing material can and plays sealing process, and the central authorities of gag have an aperture, are the paths of extruding of packing material, also can only stay the sealing blind hole, are opened by the user and extrude path.Over cap (1) is used for cutting off the influence of air to the container inner package, prevents the dry and hard inefficacy of packing material.Over cap (1) selects to adopt screw thread or connect-disconnect structure with cooperating by the producer of shell (12).Anti-slop serrations (2) is designed to one with container (11), and it is non-slip that anti-slop serrations can allow finger grip when rotating, and the bossing of anti-slop serrations itself becomes the installation site qualification that container (11) inserts shell (12) again.Ratchet (3) is designed to one with shell (12), guarantees that packing container can only rotate to a direction.Ratchet (4) is designed to one with packing container (11), and the inclined-plane can guide ratchet to insert shell (12) smoothly, and ratchet draws in when inserting shell, and ratchet leans on the resilient support of self to be stuck in the ratchet after inserting shell.Piston (5) is made for rubber, and by the elasticity of self and the inwall closed contact of packing container, the packing material of piston upward movement squeeze receptacle inner chamber (10) can only flow out from the path of regulation.(6) one of piston holders are inserted in the cross blind hole of piston (5) below, prevent that piston from following container (11) and rotating, simultaneously the rigidity of Reinforced Rubber piston; In the cross chamber that is inserted on the spiral handspike (8), make the piston holder follow spiral handspike and rotate, spiral handspike provides thrust upwards simultaneously.Piston holder (6) and spiral handspike (8) can be designed to one under the situation of packing device production technology permission.Nut (7) can be made the inwall that separate part is stuck in packing container (11) lower end, also can be designed to one with packing container, and nut only allows to rotate with packing container, can not slide.Resistance transduction bar (9) design is on base, and rear base is finished in assembling and shell (12) becomes one.Resistance transduction bar (9) is inserted in the cross-hole of spiral handspike (8), anti-slop serrations (2) on the unidirectional rotation container (11), spiral handspike (8) is because the obstruction of resistance transduction bar (9), can not follow container rotates together, can only promote piston (5) upward movement along resistance transduction bar (9), open slot on spiral handspike (8) screw thread can reduce the resistance of upward movement, finishes the container inner package neatly by extruding the outer process of container that is routed to.

The pitch of the utility model device spiral handspike is according to the consumption of extruding commonly used, selection standard pitch or the non-standard pitch of all kinds of packing materials.In pitch one regularly, the distance of the angle of rotation decision piston upward movement, the angle of rotation has determined ratchet to cross the number of ratchet again simultaneously.Ratchet can send the sound because elastic force acts in the rotation when dropping on the ratchet tooth root by the ratchet crown, and the prompting user controls the extrusion capacity of container inner package.
