CN202242500U - Projecting elastic pen cap - Google Patents

Abstract

The utility model discloses a projecting elastic pen cap, which is characterized by being made of a soft material, wherein one end of the projecting elastic pen cap is provided with a hole into which a pen holder can be sleeved; and the other end of the projecting elastic pen cap has an expansible structure, and is an extension end at which a plurality of normally-closed incisions are formed. The projecting elastic pen cap disclosed by the utility model can be sleeved on the pen holder in normal times for protecting a pen point; when writing is required, the projecting elastic pen cap can be continually sleeved inwards, and the pen point breaks through the expansible structure of the projecting elastic pen cap to open the incisions, and extends out of the incisions, so that writing can be performed; and after writing, the projecting elastic pen cap can be pushed outwards, so that the pen point is covered.

Description

Can lean out the formula separable type elastic cap

Technical field:

The utility model relates to a kind of cap for brush, particularly relates to a kind of formula separable type elastic cap that leans out, and belongs to the technical field of stationery.

Background technology:

Pen is indispensable articles for use in people's learning life, and from ancient times to the present, pen has writing brush, the quill-pen that Europe is early stage; The pen that occurred modern age, pencil, gel ink pen had appearred again in kinds such as ball pen in recent years; Adorn a kind of organic solvent in the pen, its stickiness is lower, thicker than water-based pen and ink than oiliness pen and ink, when writing; Ink just can change into liquid ink by semisolid through nib, and gel ink pen ink biggest advantage is that each melted ink all is to use on nib; Can not volatilize, leak, thereby can provide like soyeux cunning along writing sense, mobile smooth and easy the stablizing of ink.Also have ballpoint pen, ballpoint pen can be divided into oiliness and neutrality: the characteristic of oiliness atom pen and ink is that the ink stickiness is high, water-based is strong, but oil stain is more; The ink viscosity of neutral atom pen is moderate, oil stain is few, write smoothly, and is water-fast and light resistance is all good than oiliness ballpoint pen ink.These pens are applicable to different occasions respectively, have use advantage separately, receive people's popular welcome.

The core component of pen is nib, and nib is directly to be used to the parts write, in case the nib protection is improper, is damaged, and tends to directly cause scrapping of whole pen.For example the nib of pen can be bumped askewly, and the nib of pencil can fracture, and the nib of ball pen is a ball; Damage can cause it fuel-displaced not smooth, even can't write, in order to protect nib; People work out a lot of devices, and ancient times, plastic process was undeveloped, and people usually use bamboo or wooden pen container to store pen; Pen is poured in the pen container, nib up, thereby the protection nib be not destroyed.In the pen or goose quill and some ball pens or gel ink pen in modern age, often use the metal or the plastic cap for brush to be enclosed within on the nib, nib is broken when dropping to prevent pen.Even also having some ball pens or gel ink pen, the pen core in it is provided with spring and telescoping mechanism, can nib stretched out or is withdrawn within the penholder through Push switch.

The utility model content:

The technical problem that the utility model will solve is: pen of the prior art much is a structure of taking overlapping on the penholder cap for brush, is not destroyed with the protection nib.But the problem of bringing thus is: the cap for brush since all be can with the penholder separated structures, causing a major issue is exactly that the cap for brush is lost easily, the almost all people once met such problem, was exactly that the cap for brush is lost in use for some time.

For solving the problems of the technologies described above, but the utility model discloses a kind of Pop-up separable type elastic cap, concrete technical scheme is following.

A kind of formula separable type elastic cap that leans out is characterized in that: the said formula separable type elastic cap that leans out is processed by soft material, and the one of which end is for being inserted in the hole of penholder, and the other end is the expansible structure, and it is formed with a plurality of external parts of closed otch at ordinary times above being.

Preferably, the said formula separable type elastic cap that leans out is processed by rubber.

Preferably, the said formula separable type elastic cap that leans out is processed by flexible plastic.

Preferably, said otch is two.

The beneficial effect of the utility model is: utilize the leant out formula separable type elastic cap of the utility model, can be enclosed within ordinary times and protect nib on the penholder, when needs write; Can the said formula separable type elastic cap that leans out continued to be inserted in inwards, then nib will be broken through the said expansible structure that leans out the formula separable type elastic cap, and otch is strutted; And stretch out from said otch; Thereby just can write, and can be with the said formula separable type elastic cap that leans out to extrapolation after writing, thereby hide nib.

Description of drawings:

Fig. 1 is meant that the described formula separable type elastic cap that leans out of the utility model is at the outside sketch map that hides under the nib state;

Fig. 2 is meant that the described formula separable type elastic cap that leans out of the utility model is in the schematic internal view that hides under the nib state;

Fig. 3 is meant that the described formula separable type elastic cap that leans out of the utility model is at the outside sketch map of writing under the word state;

Fig. 4 is meant that the described formula separable type elastic cap that leans out of the utility model is in the schematic internal view of writing under the word state;

Wherein, Reference numeral 1-can lean out the formula separable type elastic cap, 2-otch, 3-expansible structure, 4-penholder.

The specific embodiment:

Combine accompanying drawing that the utility model is done further explanation at present.

Shown in Fig. 1-4; A kind of formula separable type elastic cap that leans out; It is characterized in that: the said formula separable type elastic cap 1 of leaning out is processed by soft material, and the one of which end is for being inserted in the hole of penholder 4, and the other end is an expansible structure 3; It is formed with a plurality of external parts of closed otch 2 at ordinary times above being, said otch 2 is two.

Claims (4)

1. one kind can lean out the formula separable type elastic cap, it is characterized in that: the said formula separable type elastic cap that leans out is processed by soft material, and the one of which end is for being inserted in the hole of penholder, and the other end is the expansible structure, and it is formed with a plurality of external parts of closed otch at ordinary times above being.

2. the formula separable type elastic cap that leans out as claimed in claim 1 is characterized in that: the said formula separable type elastic cap that leans out is processed by rubber.

3. the formula separable type elastic cap that leans out as claimed in claim 1 is characterized in that: the said formula separable type elastic cap that leans out is processed by flexible plastic.
