Description

Connect the method for label to tea-bag

The present invention relates to a kind of method that connects label to tea-bag, be particularly useful for connecting a label to the filter bag that comprises tealeaves, bluish yellow chrysanthemum and similar products, use single line one end to be fixed in bag, the other end is fixed in label and is formed on brew process or takes the mode easily of bag own afterwards.

In present description, quote diphyllous tea-bag as a reference but therefore do not limit application to other kinds tea-bag.

Diphyllous tea-bag is the tea-bag of prevailing single dose, and it folds with longitudinal sealing a slice filter paper and form a pipe by continuous rolling; When pipe formed, cargo-carring product was placed on the filter paper at the well-regulated gap location of longitudinal direction; Then with the name part of pipe at the center, be folded into a W shape between two continuous fillings be called a bag drop ear so that form, each has comprised the product of amount.At last, two drop ears press mutually, they to open end sealed, simultaneously wire joint to sealed end directly in their label.

The tea-bag of making in this way can be picked up and dispose with line, and after it had been placed in the boiling water, the other end was fixed in label because an end of line is fixed in bag especially, and label can be held easily between finger.

The sealing of bag and subsidiary line can work by different way.

US Patent 2307998 discloses a kind of tea-bag and has made its method, and the static line of this method imagination is summed up as prior art in the knot of bag and label; In the accompanying drawings with describe in one of example, line on shackle, tie a knot by a shackle be fixed in label and bag, in another embodiment, only pass through knot.

According to described patent, knot can not make itself high-speed production; The industry of today has adopted shackle as the fastest and effective and efficient manner is fixed in tea-bag with label.

Yet, the shortcoming of this method, especially for the fixed labels line on bag, be that shackle by the metal manufacturing can pollute and makes tea, produce a kind of disagreeable taste, even health problem.

The other method of fastening line is in US Patent 4,415, and 597 describe, and it discloses a kind of filter bag that is made of the filter paper that applies the thermoplastic material heat sealing layer, and it has a label is fixed by a line, and this line one end remains between two heat seal edge of bag; Beat the heat seal of taking apart around the bag winding and at several somes place, bag outside.Therefore, bag or at least its part make by paper and thermoplastic material.

Such material has and is similar to above-mentioned shortcoming, because thermoplastic material and infusion material contacting to pollute by the material in the thermoplastic material and make tea at high temperature.

Other shortcomings of the bag of this patent disclosure are expenses of thermoplastic material, and it is high than common filter paper.

The objective of the invention is to eliminate shortcoming above-mentioned.

The present invention as the feature of claim, fixes a line and reaches this purpose in a tea bag and a label by providing one, this line fixing only by a knot and do not use any metal shackle or heat-seal process.

Feature of the present invention is arranged in the following claim and the details description below of disclosed advantage is expressed, and retouches the accompanying drawing that reaches with reference to following, and the present invention represents preferred embodiment by example, wherein:

Fig. 1,2,3,4,5 and 6 is schematic side elevations that some parts cuts, and has represented the continuous series of steps of the process of method disclosed herein;

Fig. 7 is the top of tea-bag constructed in accordance, block diagram;

8,9,10,11 and 12 is schematic side elevations that some parts cuts, and has represented the details of presumable parts and step among the embodiment that aforesaid figures represents;

Figure 13,14,15,16,17 and 18 is scheme drawings that some parts cuts, and has represented to be embodied in the continuous series of steps of another process of this disclosed method;

Figure 19,20,21,22 and 23 is scheme drawings that some parts cuts, the continuous series of steps of expression another embodiment of the present invention.

Described referring now to the accompanying drawing of last table by method disclosed by the invention, they are not same size entirely, in order that represent details of the present invention preferably.Make a label, the method that is connected to tea-bag 2 is to use one section one end to be fixed in the line 3 that the tea-bag other end is fixed in label 1.

Tea-bag 2 and label 1 have at least an edge 5 that reduces thickness that line 3 can be fixed on this edge.

According to employed equipment, line 3 is connected in bag can be connected in label 2 the time, or two operate in different phase and implement.

Shown in Fig. 1-6 and 8-12, the present invention can comprise following step especially.

The first step (being N/R in some cases) comprises and line 3 is cut into required separation distance adds and makes at least two described length of knot between label and the bag, the length of last line 3 is arranged by this way, makes its at least a portion be opposite to (being parallel to stretching) and fixes its edge 5.

In connecing down step,, line is the first step if need not cutting, the eye 41 of first end of line 3 or go between 3 ' by pin 4 is hooked.

Pinprick is opening, as shown in Figure 8.

Pin runs through a value L4 to the relative edge with first direction R insertion edge 5 then, is enough to make form an annular 30 on the line 3, just forms a part, is bent at this line 3, as shown in Figure 2.Then, have only pin 4 to be extracted out by edge 5 and around its axis X and reverse at least 180 ℃, make remaining two-wire part longer so that over-width ring 30 forms an eye 32 than the part that spicula goes out along direction F by part.In Fig. 3, dotted line represents that pin moves position afterwards, D at first ₄The position that the expression pin is partly extracted out.

Pin 4 at least 180 rotatablely moves down loop section is torqued on himself, and it is a knot that its profile is suitable for.

31 insertions that go between then are drawn out with release wire 3 by eye 32 and the pins 4 that ring 30 limits, and the latter is subjected to stretching action to fasten last knot 33, shown in Fig. 4,11 and 12.

In fact, when line 3 is stretched, almost completely arrived a side that produces stretching action by 3 edges 5, when the part of lead-in wire 31 and line 3 is retained in opposite side, the part of line at the edge 5 below by and knotting.

In case knot 33 has been fastened, two further steps shown in Fig. 5 and 6 can carry out to obtain to be similar to the final products of Fig. 7.

At these two final steps (Fig. 5 and 6), line 3 parts between label 1 and bag 2 become a coil 35 by curling to flock together.

With tea bag 2 and label 1 force together, the coil 35 of line 3 is between them then.

Label 1 can be made and by only being connected to bag 2 at 2: 11 heat seals, be that is to say, in two very limited zones by the paper that scribbles the agent of low temperature hot adhesion.

The patterned heat sealing of label 1 and bag 2 forms label 1, and adhesive agent 11 is retained on the label 1 so that label 1 can easily be left behind at this moment from bag 2 in removable connection between coil 35 and the bag 2.

In brew process, therefore, adhesive agent does not contact with the boiling water that is used to make tea.

Shown in Figure 13 to 18 (for the convenient attachment of only having represented label 1), line can be similar to the logical crochet hook of the back of the body in many aspects by crochet hook operation, in this case, and the description above this step that embodies disclosed method is different from aspect following.

At first, eye 41 lines that hook 3 parts by crochet hook 4 are on label 1 opposed edge, as Figure 14 finding.

Pin 4 was inserted the edge then, hooked line 3 and retracted it by described edge along first direction R, and this mode is similar to above-described first embodiment imagination, and is shown in Figure 15,16 and 17.At Figure 18, pin 4 is along-5 first direction R ¹Opposite direction R partly retracts; Reverse at least 180 ° around its X then, longer so that over-width ring 30 forms hole 32 in the two-way part of other end remainder than the part that spicula goes out.

Go between then and 31 pass hole 32, subsequent steps is for example fastened node 33, is identical with the imagination of above-mentioned first embodiment.Another embodiment of the disclosure method is illustrated in Figure 19 to 23 and on the pattern of determining eye 32 different principles is arranged.

In the above-described embodiments, eyelet 32 is extracted pin 4 formation out by part.Yet in the embodiment of Figure 19-23, ring 30 is broadened.

In fact, the pin 4 that is used for this embodiment has first 41 of close needle point 40 and along its second 42 (accompanying drawing is in the left side).

Once pin 4 inserts edge 5, what describe in accompanying drawing is bag 2, and the profile that pin and line adopted is illustrated in Figure 19 and 20 with lateral plan and top view respectively.Having inserted edge 5 numerical value is L ₄Pin 4 be enough to be used in making

eye

41 and 42 at opposite side and determine annular 30.

This embodiment has imagined the device 7 that is used to hook line 3, and described device is represented with Y-piece in the accompanying drawings.Device 7 moves at direction N (vertical direction in the accompanying drawings), and this direction is basically perpendicular to the direction that pin 4 passes edge 5.Describe in detail as Figure 21, device can be made up of the Y-piece that has hook end 70, when hook spare 7 movable or when hooking the position, hook end 70 passes through second.

Basically, ring 30 is broadened by the mutual action with hook spare 7, hook spare 7 be pulled through more line to the edge 5 sides (ring 30 is there), form hole 32 by this way, this has also described at another embodiment, goes between 31 to pass by this ring.Contemplated the same of the step that continues and Fig. 1-18 promptly goes between and 31 passes hole 32, fastens knot at last.

The present invention can be changed and change and not break away from the scope of notion of the present invention.In addition, details of the present invention can be replaced by technical equal part in addition.
