Description

A kind of pump head directive texture

Technical field

The utility model relates to liquids packaging product field, more specifically, relates to a kind of pump head directive texture for packing container.

Background technology

Packing container is the requisite containers of most of daily necessities, such as liquid detergent Packaging Bottle, shower cream Packaging Bottle, hand cleanser Packaging Bottle etc.In general, in order to allow user take out liquid in Packaging Bottle easily, the lid of Packaging Bottle generally can install a pump head structure, as long as user's pressing pump head, the liquid in Packaging Bottle just can be drawn out of the external world by pump head, uses for user.

The pump mouth of general pump head and facing are revocable, and facing can rotate arbitrarily, when Packaging Bottle has direction to require, in process of production, be fixed by the direction of clamp fixture by corresponding for pump mouth bottle, then lock facing, or directly lock pump head facing, pump mouth direction is free position.Be fixed pump head for facing and pump mouth, because assembling the difference of moment of torsion, pump mouth is just different with the angle of Packaging Bottle, causes harmful effect, even affect function to the conformability of product appearance.

Utility model content

The utility model, for overcoming the defect described in above-mentioned prior art, provides a kind of pump head directive texture for packing container.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is:

A kind of pump head directive texture, comprise pump head and bottle, described bottle comprises bottleneck, the shell that described pump head comprises pump mouth, the facing be connected with described bottleneck thread and is connected with facing, bottle is divided into front portion and back portion by one shaft section of described bottle, the edge of described facing is provided with at least one piece of block, described bottleneck is provided with the projection for blocking described block, described block is corresponding with the position relationship of described projection, makes the plane of symmetry of described pump mouth and the plane of symmetry of described front portion form the angle of 0 ° ~ 45 °.

Because pump mouth and facing fix, pump mouth rotates along with the rotation of facing, by arranging block and projection respectively on the edge of described facing and the bottleneck of bottle, described block is corresponding with the position relationship of projection, when described facing is connected with neck thread, when facing is tightened onto to a certain degree on bottleneck, the projection on described bottleneck and the block of facing offset, projection can not continue to screw in, and at this moment pump mouth just reaches predetermined fit angle with bottle.

Described facing edge can arrange one piece or multiple pieces of blocks, preferably, arranges the block that two pieces of positions are relative.

Further, described facing is provided with anticreep stop block, described anticreep stop block is positioned at the side of described block, described anticreep stop block is positioned at the contrary side of hand of rotation when described projection screws in, make described projection can be fastened between described anticreep stop block and block, the position of pump head can be fixed further, make pump head be less likely to occur to rotate, thus reach anti-loose function.

Further, described anticreep stop block is provided with importing circular arc, so that described projection screws between described anticreep stop block and block, reduces the resistance that projection screws in.

The convex surface of described importing circular arc is relative with the outside of described bottleneck.Further, the hand of rotation when radian of described importing circular arc screws in along described projection diminishes, and the spacing between making to import outside circular arc and neck part diminishes gradually, the screw-in of projection is played to the effect of guiding.

Further, the side that described projection contacts with described anticreep stop block is provided with fillet, to ensure that described projection is convenient to screw out, but has enough resistances.

Further, described shell is provided with the U-lag of restriction described pump mouth activity, and described U-lag extends along the direction of axis line of described shell, makes described pump mouth can be up and down along U-lag.

Further, the length that described block and anticreep stop block contact with bottleneck projection is less than 50% of described facing lead of screw thread.

Compared with prior art, the beneficial effects of the utility model are:

Pump head directive texture described in the utility model, by arranging block and projection respectively on described facing and bottleneck, described block is corresponding with the position of projection, when described facing is threaded with bottle, when facing is tightened onto to a certain degree on bottleneck, the projection of described bottleneck and the block of facing offset, pump head can not continue to screw in, now pump mouth just reaches predetermined fit angle with bottle, effectively solves the orientation problem of pump mouth, increases unitarity and the aesthetic property of Packaging Bottle.

Detailed description of the invention

Below in conjunction with detailed description of the invention, the utility model is further described.Wherein, accompanying drawing only for exemplary illustration, expression be only schematic diagram, but not pictorial diagram, can not be interpreted as the restriction to this patent; In order to embodiment of the present utility model is described better, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual object; For a person skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.

embodiment 1

As shown in Fig. 1 ~ 3, a kind of pump head directive texture, comprise pump head 1 and bottle 2, bottle comprises bottleneck 21 and shoulder, the shell 13 that pump head 1 comprises pump mouth 11, the facing 12 be connected with bottleneck thread and is connected with facing 12, pump mouth 11 and facing 12 fix, bottle is divided into front portion and back portion by one shaft section B of bottle 2, facing 12 edge is provided with the relative block 121 in two pieces of positions and anticreep stop block 122, and the length that block and stop block contact with bottleneck projection is less than 50% of facing lead of screw thread.The outside of the bottleneck 21 of bottle 2 is provided with projection 211, and the distance X between projection 211 and shoulder is greater than 3mm, and the height H of projection 211 is greater than 1mm, and length B is 1 ~ 3.5mm, and projection 211 is corresponding with the position of block 121.When facing 12 is threaded with bottle 2, when facing 12 is tightened onto to a certain degree on bottleneck 21, projection 211 and the block 121 of bottleneck 21 offset, now pump mouth 11 and bottle 2 reach predetermined fit angle, specifically, the plane of symmetry C of pump mouth 11 and the plane of symmetry of bottle 2 front portion form the angle of 0 ° ~ 45 °, and be preferably 0 °, namely the plane of symmetry C of pump mouth 11 and the plane of symmetry of bottle 2 front portion coincide.

As shown in Figure 4, anticreep stop block 122 is positioned at the contrary side of the hand of rotation of block 121 when described projection 211 screws in, make projection 211 can be fastened between anticreep stop block 122 and block 121, further the position of fixing pump head 1, make pump head 1 be less likely to occur to rotate.Anticreep stop block 122 is provided with and imports circular arc 1221, and the convex surface importing circular arc 1221 is relative with the outside of bottleneck 21, and the setting importing circular arc 1221 can reduce the resistance of projection 211 screw-in, so that projection 211 screws between anticreep stop block 122 and block 121.The hand of rotation when radian of importing circular arc 1221 screws in along projection 211 diminishes, and the spacing between importing outside circular arc 1221 and bottleneck 21 diminishes gradually, the screw-in of projection 21 is played to the effect of guiding.

The side that projection 211 contacts with anticreep stop block 122 is provided with fillet, to ensure that projection 211 is convenient to screw out, but has enough resistances.
